Automatic Plywood Woodworking Core Veneer Composer Machine

Plywood Woodworking Core Veneer Composer Machine

What is the working principle of veneer composer machine?

The veneer composer machine is one of the main equipments for the production of blockboards (large core boards). It is mainly used to make standard laths made of raw materials such as small-diameter logs, rotary-cut wood cores, and lumber skins, and then through the processes of arranging boards, gluing, extrusion, and heating to make solid-core boards of the entire width. The veneer composer is mainly composed of five parts: the main unit of the veneer composer machine, the hydraulic station, the feeder, the discharge table and the control system. The splicing machine is controlled by PLC. It has the characteristics of high degree of automation, convenient operation, low labor intensity, short splicing cycle, and labor saving.

What is the scope of work of the veneer splicing machine?

The veneer splicing machine is mainly used for the production of plywood, multi-layer board, LVL, floor substrate, craft furniture board, building laminate, container board, melamine ecological board, blockboard and other rotary cut 1.0-4.0mm thickness. Horizontal splicing of panels (also called sandwich skin). Change the traditional manual laying process and realize the full process and automation of plywood. Scattered and irregularly cut middle plates are spliced into whole plates of any size through the machine's complete program operations such as width detection, thickness sorting, cavity detection, edge trimming, glue splicing, fixed-length cutting, stacking and palletizing.

The core board splicing machine is suitable for the splicing of core materials in the plywood production line. It can connect core veneers of different lengths and sizes with high-strength threads and hot-melt adhesives, which facilitates the production in the subsequent stages of the plywood production line. The whole process can be operated by one worker, saving time and high efficiency.

What are the parts of the veneer splicing machine?

1. Body of  veneer splicing machine: The whole body is an engineering steel structure, which is stable and reliable.

2. Side pressure and loading frame of the  veneer splicing machine: The side pressure is composed of a pressure plate and an oil cylinder, which ensures that the side of the workpiece is aligned during work. After the workpiece is placed, it can be conveniently put into the pressing position by the loading rack, and it can be unloaded smoothly when unloading.

3. The main pressing part of the  veneer splicing machine: it is composed of a push plate and an oil cylinder. When the workpiece is placed in the pressing position, the manual reversing valve is switched to the pressing position for pressing.

4. The locking part of the loading rack: it is composed of a cylinder, a connecting rod and a lock sleeve. When the loading rack is closed, pull the manual reversing valve so that the lock sleeve buckles the loading rack to perform pressing operation. When unloading, the lock sleeve must be opened first.

5. Hydraulic system of the  veneer splicing machine: Due to the special requirements for the lamination of the wooden house components, the hydraulic system of this machine tool is specially designed to meet the special needs.

6. Electrical control system: Since the machine tool is composed of 4 groups of units, its control part is composed of 4 independent control units, which can be operated separately or jointly.

7. Reversing valve: the main operating part of the machine tool, the reversing valve on each component controls the opening and closing of the loading rack, side pressure advance and retreat, and main pressure advance and retreat respectively. There is a throttle valve behind the reversing valve that controls the opening and closing of the loading rack to control the opening and closing speed of the loading rack, thereby ensuring the synchronization with other unit loading racks.

8. Pneumatic system: Control the locking of the loading rack, and the manual reversing valve controls the opening and closing of the lock.

How to operate the veneer composer machine correctly?

The correct operation of the veneer composer machine is very important to the quality of the plate processing and the safety of the staff, so when working on the woodworking composer machine machine, it is mainly operated according to the following sequence.

1. The boards to be spliced need to be coated with glue first. For gluing, it is best to apply glue on both sides.

2. Transport the veneers that need to be spliced to the automatic feeding table. The splicing size of the splicing machine is generally 1300*2500mm, and the thickness can be spliced below 60mm or 150mm depending on the model. Special requirements can also be customized configuration design.

3. Using high-frequency heating, the glue can be quickly cured in a short time. The whole working process takes about 3-5 minutes.

4. The spliced veneers can be automatically stacked through the conveyor line for the next process.

What are the common faults of veneer composer machine?

1 Plate ignition is the plate discharge caused by short circuit or overcurrent. The solution is to first find out the cause of the ignition. Generally, several common situations are that too much glue causes the glue to overflow to the upper and lower plates, or the wood has serious scars. According to the specific reason, it can be smoothed at the place where the fire is fired. Another situation is that there may be metal objects in the wood that may cause a short circuit between the upper and lower plates, and the ignition will be more serious. The plate may be penetrated. The penetration part is repaired with a stainless steel electrode and then polished to make it smooth.

2 Overcurrent, basically due to improper adjustment by the customer and current mismatch. The manufacturer requires the operator to be a skilled electrician to receive professional training from the high-frequency manufacturer. After changing the thickness of the panel, the high frequency must be readjusted. In addition, if the operator is changed frequently, various troubles will occur because the new operator is not familiar with it.

3. Some small accessories manufacturers will give some for free when they deliver the goods, or discuss with the manufacturers to prepare some vulnerable accessories to avoid delaying the production cycle due to equipment waiting due to remote roads.

How to maintain the veneer composer machine?

The veneer composer machine also has its own service life. After a few years of use, its performance is different from that of a new one. After a long time, some parts will be worn out and damaged. Our daily maintenance is to prolong its service life. Under what conditions will its application time be longer?

Reasonable use of the veneer composer machine can prolong its service life. The temperature and humidity mean the influence of the use environment on it. The operating humidity of the veneer composer machine should be in the range of 30%~90%; the ambient temperature should be 0-45°C, and the principle of temperature change should not cause condensation. Dust will inevitably appear during work, and the dust concentration should not exceed 10mg/m3;

Usually, the veneer composer machine is installed indoors, because it is necessary to avoid direct sunlight for a long time, and to avoid affecting its use due to changes in ambient temperature.

Daily maintenance work is naturally indispensable. On the one hand, the problems of the veneer composer machine can be found in time and corrected in time, and the failure rate can also be reduced.
