What Is Veneer Composer Machine?

The veneer composer is one of the main equipment for plywood production. It is mainly made of small-diameter logs, rotary-cut wood cores, lumber skins and other raw materials. After arranging, gluing, splicing, heating and other processes Equipment for making full-width solid core panels. The veneer composer is mainly composed of hydraulic system, pneumatic system and so on. The veneer composer machine is a special splicing equipment in the processing of furniture, handicrafts, solid wood doors, panels, etc. The operation of the veneer composer machine is simple and flexible, and it has a remarkable effect in improving production efficiency, increasing the rate of finished products, and reducing waste of raw materials.

What Veneer Is Suitable For The Veneer Composer?

The veneer composer is suitable for various wood raw materials, such as small diameter logs, rotary cut wood cores, board veneer and other raw materials. Various random sheet sizes can be made into gauge planks. For example, the rotary-cut veneer used for plywood has different specifications, the surrounding is uneven, and the surface has wormholes, etc., all of which can be achieved through the process of detection-cutting-gluing-splicing of the veneer composer to meet the specifications.

What Does The Veneer Composer Consist Of?

This equipment is mainly composed of the main machine of the veneer composer, the cutting part, the automatic gluing and bonding machine, the auxiliary heating system, the automatic feeding machine, the discharging table and the control system. The machine is controlled by PLC (PLC can be selected according to customer preference), which has the characteristics of high degree of automation, simple and convenient operation, short splicing cycle and labor saving. The equipment is all welded and formed with high-quality steel, and the surface is polished and finished, which not only has a beautiful appearance but also has a long life.

How Does The Veneer Composer Work?

The splicing size of the veneer composer machine is generally 4*8 feet, 6*8 feet, 8*4 feet, 5*10 feet, etc. The thickness can be less than 60mm or less than 150mm depending on the model. If there are special requirements on the size, a tailor-made configuration design can be carried out. The equipment adopts high-frequency heating, which can make the glue solidify quickly in a short time. The whole working process takes about 3-5 minutes.

The working process of the automatic veneer composer machine is mainly divided into 8 processes, and these 8 processes cooperate with each other and cooperate with each other to complete the work together. These eight steps are the eight processes of feeding and conveying, sheet correction, front drive, cutting and control, rear drive, butt joint panel, finished panel cutting, and finished panel receiving. First of all, put the material boards to be spliced flat on the conveyor belt for transmission, and the conveyor belt will transport the material boards, and then correct them by the side by the correction device, so that the sides are aligned, so that the finished boards that are spliced are aligned As a benchmark, it is easy to operate the opposite side in the production process of plywood; the corrected sheet is transported to the front drive, and after the sheet enters the front drive to be flattened and conveyed, it is detected by the pressure wheel micro switch and calculated by the rotary encoder Cutting distance, the pulse signal is sent to the PLC, and the cutting program is executed in combination with the set cutting data on the displayed text. Half of the process has been carried out so far. The next part is that the front part of the rear drive in the second half is designed as a device that can move up and down. It will fall flat when it needs to receive and transfer materials, and it will be used for receiving and transferring materials. When the material plate is driven by the rear drive, the adhesive photoelectric switch will control the lifting of the glue claw, and touch the hot melt glue on the glue claw to the cross-section of the moving material plate. The spliced boards are connected together to form an infinitely long whole. The finished boards that have been spliced and cut within the specified size are conveyed into the board receiving rack through the conveyor belt. The function of the board receiving machine is to automatically stack and arrange the finished boards neatly.

What Are The Factors Affecting The Finished Product Of Veneer Splicing?

When doing wood splicing, the quality of the final spliced finished board will be affected by many factors, such as glue quality, board treatment and so on. Among them, every operation step in the splicing process will affect the quality of the final spliced panels. Therefore, the manufacturer needs to ensure the correctness of the veneer composer operation.

Select and process the plates. We need to select quality-qualified plates and quality-guaranteed plates from all the plates in order to ensure the quality of the finished plates. In the selection of boards, a moisture content control is required. Generally speaking, it is best to control the moisture content between 8-12%. The difference in moisture content of a whole board cannot exceed ±2%, while the moisture content of two adjacent boards The difference cannot exceed ±1% (of course, different tree species have different water content standards, which can be adjusted). Generally speaking, controlling the fluctuation of the moisture content of the wood within 2% can reduce the shrinkage of the wood and ensure the toughness and moisture resistance of the board. Then, do planing and cleaning of the bonding surface to ensure flatness and cleanliness.

Workflow After Veneer Composer

Glue The Veneer After Veneer Composer

1. For the glue glued on the surface of the veneer, according to the standard ratio, carry out the weighing of the glue main agent and curing agent to ensure the accuracy of the ratio. Then, mix the well-proportioned main ingredient and curing agent together, and stir fully to ensure the uniformity of mixing. In addition, after the glue is prepared, it needs to be used up within the specified time, that is, to ensure that the prepared glue is used up within the usage time. Glue preparation is usually mixed with glue barrels. The high-speed glue mixing barrel rotates fast, which can evenly mix the main agent and curing agent together and fully stir. Save labor to a great extent.

2. After the glue has been prepared and the splicing boards are ready, we need to apply the glue to the bonding surface of the eucalyptus boards. First of all, according to the standard amount of glue, the glue should be applied to the bonding surface of the board to ensure that the amount of glue on the bonding surface is sufficient; then, the glue on the bonding surface should be brushed to ensure that the painting is even sex. We usually choose glue spreader. There are mostly 4-foot, 5-foot, and 8-foot glue spreader on the market, and other specifications can be customized, which is mainly determined by the size of the board. The glue mixing machine is connected to the glue barrel and spread evenly on the roller of the glue spreader, and the sheet passes through the roller from the feed port to apply the glue to the bonding surface of the sheet. The operation is simple, the brushing is uniform, and the effect of reducing glue waste and improving the quality of the veneer is remarkable.

Plywood Press Line

1. After applying the glue, we will compound the eucalyptus boards together and take them to pressurize. Here, we must pay attention to the timeliness of the operation, which needs to be completed within the specified time. In the process of pressurization, three points need to be paid attention to: first, the pressurization pressure should be sufficient; second, the pressurization pressure should be uniform; third, the pressurization time should be sufficient.

Cold press: The cold press is the normal temperature, and it depends on the time to press the product. The cold press can be completed by keeping it under a certain pressure for several hours.

Cold Press Machine

Hot Press Machine:

The working efficiency of the hot press machine should be fast, because the product is quickly formed by temperature, and the speed is fast. In principle, the heat press machine uses heat conduction oil to heat and then the heat conduction oil enters the press plate. Each layer has heat conduction oil. After the temperature rises to 120°, the product is quickly shaped, and the product is taken out after automatic cooling.

2. Do Health Maintenance After Decompression

After fully pressurized, we can splicing whether it is possible to release the pressure by observing the glue lines or glue droplets extruded by pressure. After the pressure is relieved, it is not possible to do deep processing immediately or use it directly, but to carry out a sufficient time of health preservation to ensure that the splicing adhesive can reach a fully cured state, so as to firmly bond the board.
