Description

Technical Field

[0001] The invention relates to the technical field of plate processing, and in particular to a high-efficiency and energy-saving plate composite cold-pressing forming machine and a cold-pressing forming method. Background Art

[0002] In the current field of plywood production technology, the traditional plywood cold pressing process has always occupied an important position. However, with the continuous improvement of product quality requirements, this traditional process has gradually exposed some problems that cannot be ignored.

[0003] The traditional cold pressing process of plywood usually involves stacking the paved and formed board blanks together and then placing them in a cold press for cold pressing. In this process, the veneers at the bottom of the stack not only have to bear the pressure applied by the cold press, but also the double influence of the gravity of the veneers located on the top. This situation makes the forces on the upper and lower veneers in the stack extremely uneven. The veneers at the top are mainly subjected to the relatively single pressure applied by the cold press, while the veneers at the bottom, while bearing the pressure of the cold press, also have to bear the gravity from the many veneers above. If the number of veneers is reduced, the processing efficiency will be affected. If the number of veneers is large, the quality of the board will be affected.

[0004] When there are a large number of veneers, the uneven force is very likely to have a serious adverse effect on the cold pressing effect. On the one hand, it may cause the board surface to shift, making it impossible for the layers of veneers of the plywood to fit tightly, affecting the overall structural stability of the product. On the other hand, it may also cause cracking problems. Under the action of uneven pressure, the internal structure of the veneer is easily damaged, resulting in cracks, which greatly reduces the strength and service life of the plywood. At the same time, bubble board situations may also occur. Uneven pressure will cause uneven distribution of adhesives, thereby forming bubbles, affecting the appearance quality and performance of the plywood. In addition, deformation is also one of the common quality problems. Due to uneven force, the veneer may be twisted, warped and other deformations, making the plywood unable to meet the specified size and shape requirements. Moreover, due to uneven pressure, it may also cause direct damage to the board, especially for some veneers with relatively fragile materials, which are more likely to be damaged under such adverse pressure environments, further increasing production costs and reducing production efficiency.

[0005] In summary, a series of quality problems caused by uneven force on the upper and lower veneers in the traditional plywood cold pressing process have become an important issue that needs to be urgently solved in the current plywood production field. Summary of the invention

[0011] Optionally, the bottom plate has a placement position and a plurality of mounting grooves, the plurality of mounting grooves are arranged along the periphery of the placement position and are located on the end surface of the bottom plate close to the pressure plate; and further includes: A plurality of baffles are swingably arranged in the installation groove. After the baffles are swung, they are at a certain angle with the bottom plate or enter the installation groove. After the baffles are swung into the installation groove, the upper end surface of the baffles is flush with the upper end surface of the bottom plate.

[0012] Optionally, it also includes: A rod, the rod is rotatably arranged on the bottom plate, and one end of the baffle is arranged on the rod; Gears are arranged at both ends of the rod, two of the gears and one of the rods form a transmission rod group, and the transmission rod group has multiple groups, and the gears of the multiple transmission rod groups are meshed end to end.

[0014] Optionally, the base plate is a split structure with an installation space inside, and the transmission rod groups are all arranged in the installation space.

[0015] Optionally, it also includes: A sound insulation pad is arranged on a side wall of the installation space.

[0016] The invention discloses a high-efficiency and energy-saving composite cold-pressing forming method for plates, which utilizes the composite cold-pressing forming machine to perform cold-pressing processing on multi-layer single plates.

[0017] The working principle and beneficial effects of the present invention are: In the present invention, the disc-shaped frame can be rotatably arranged on the machine tool, and its rotation axis is kept parallel to the ground. The bottom plate is arranged on the disc-shaped frame and is used to place the multi-layer veneer to be cold pressed. The pressing plate and the bottom plate are parallel to each other and parallel to the ground. The moving direction of the pressing plate is perpendicular to the rotation axis of the disc-shaped frame. During the processing, the operator places the multi-layer veneer to be cold pressed on the bottom plate, and then starts the pressing plate through the driving device to move it toward the bottom plate. The bottom plate and the pressing plate cooperate to perform cold pressing processing on the multi-layer veneer.

[0018] When the pressure is gradually applied to the target pressure (usually 13 atmospheres, but in actual applications it can be flexibly adjusted according to different materials or the number of single-layer boards), the driving device drives the plate frame to rotate, driving the bottom plate and the pressing plate to rotate synchronously. The rotating pressing plate and the bottom plate are perpendicular to the ground, and the multi-layer veneers in the pressing space are also perpendicular to the ground, and the cold pressing process is always vertical. In the traditional process, the veneer at the bottom not only has to bear the pressure of the pressing plate, but also the gravity of the upper veneer. This makes the pressure on the veneers at different heights significantly affected by gravity, which leads to uneven force on the veneer.

[0019] When the veneer is subjected to uneven force, the board surface may shift, which will prevent the layers of veneer from fitting tightly together, affecting the overall structural stability of the product. On the other hand, it may also cause cracking problems. Under uneven pressure, the internal structure of the veneer is easily damaged, resulting in fine cracks. These cracks will continue to expand over time, reducing the strength and service life of the plywood. At the same time, bubble board situations may also occur. Uneven pressure will cause uneven distribution of adhesives, resulting in bubbles inside the board. These bubbles not only affect the appearance quality of the plywood, but also reduce its performance. Deformation is also one of the common quality problems. Due to uneven force, the veneer may be deformed by twisting, warping, etc., making the plywood unable to meet the specified size and shape requirements. Moreover, due to uneven pressure, it may also cause direct damage to the board, especially for some veneers with more fragile materials, which are more likely to be damaged under such adverse pressure conditions. This further increases production costs and reduces production efficiency. The innovative method of arranging the veneers vertically and cold pressing them on both sides effectively avoids the influence of gravity between the veneers, greatly improves the uniformity of pressure, and provides a strong guarantee for the production of high-quality plywood.

[0020] It should be noted that during use, the maximum number of veneers that can be placed in the pressing space can be preliminarily calculated based on the pressure formula and the gravity of the veneers, and actual operation can be performed to verify. The standard is to ensure that the veneers will not be affected by gravity during the vertical cold pressing process, resulting in relative displacement or falling of some veneers. If it is necessary to increase the number of veneers in a single cold pressing, the edge fixing mechanism can be installed according to the actual situation, or the contact surface of the pressing plate and the bottom plate with the veneer can be designed to have a certain friction material, while ensuring that the surface of the veneer will not be affected by friction, so as to increase the friction coefficient with the veneer and prevent the veneer from sliding under pressure.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] Reference Figure 1~Figure 5 A high-efficiency and energy-saving plate composite cold pressing forming machine is proposed, which is used for cold pressing single board, including: a disc frame 1, which is rotatably arranged, and the rotation axis is parallel to the ground; a bottom plate 2, which is arranged on the disc frame 1; a pressing plate 3, which is movably arranged on the disc frame 1 relative to the disc frame 1, and the moving direction of the pressing plate 3 is perpendicular to the rotation axis of the disc frame 1. The pressing plate 3 is located on one side of the bottom plate 2 and is parallel to the bottom plate 2. After the pressing plate 3 moves, it approaches or moves away from the bottom plate 2. There is a pressing space between the pressing plate 3 and the bottom plate 2 for placing single board.

[0029] In this embodiment, the disc frame can be rotatably arranged on the machine tool, and its rotation axis is kept parallel to the ground. The bottom plate 2 is arranged on the disc frame 1, and is used to place the multi-layer veneer to be cold pressed. The pressing plate 3 is parallel to the bottom plate 2 and parallel to the ground. The moving direction of the pressing plate 3 is perpendicular to the rotation axis of the disc frame 1. During the processing, the operator places the multi-layer veneer to be cold pressed on the bottom plate 2, and then starts the pressing plate 3 through the driving device to move it toward the bottom plate 2. The bottom plate 2 and the pressing plate 3 cooperate to perform cold pressing processing on the multi-layer veneer.

[0030] When the pressure is gradually applied to the target pressure (usually 13 atmospheres, but in actual applications it can be flexibly adjusted according to different materials or the number of single-layer boards), the driving device drives the disc frame 1 to rotate, driving the bottom plate 2 and the pressing plate 3 to rotate synchronously. The rotating pressing plate 3 and the bottom plate 2 are perpendicular to the ground, and the multi-layer veneers in the pressing space are also perpendicular to the ground, and the vertical cold pressing process is always maintained. In the traditional process, the veneer at the bottom not only has to bear the pressure of the pressing plate 3, but also the gravity of the upper veneer. This makes the pressure on the veneers at different heights significantly affected by gravity, which leads to uneven force on the veneer.

[0031] When the veneer is subjected to uneven force, the board surface may shift, which will prevent the layers of veneer from fitting tightly together, affecting the overall structural stability of the product. On the other hand, it may also cause cracking problems. Under uneven pressure, the internal structure of the veneer is easily damaged, resulting in fine cracks. These cracks will continue to expand over time, reducing the strength and service life of the plywood. At the same time, bubble board situations may also occur. Uneven pressure will cause uneven distribution of adhesives, resulting in bubbles inside the board. These bubbles not only affect the appearance quality of the plywood, but also reduce its performance. Deformation is also one of the common quality problems. Due to uneven force, the veneer may be deformed by twisting, warping, etc., making the plywood unable to meet the specified size and shape requirements. Moreover, due to uneven pressure, it may also cause direct damage to the board, especially for some veneers with more fragile materials, which are more likely to be damaged under such adverse pressure conditions. This further increases production costs and reduces production efficiency. The innovative method of arranging the veneers vertically and cold pressing them on both sides effectively avoids the influence of gravity between the veneers, greatly improves the uniformity of pressure, and provides a strong guarantee for the production of high-quality plywood.

[0032] It should be noted that during use, the maximum number of veneers that can be placed in the pressing space can be preliminarily calculated based on the pressure formula and the gravity of the veneers, and actual operation can be performed to verify. The standard is to ensure that the veneers will not be affected by gravity during the vertical cold pressing process, resulting in relative displacement or falling of some veneers. If the number of veneers in a single cold pressing needs to be increased, an edge fixing mechanism can be installed according to actual conditions, or the contact surface of the pressing plate 3 and the bottom plate 2 with the veneer can be designed to have a certain friction material, while ensuring that the surface of the veneer is not affected by friction, so as to increase the friction coefficient with the veneer and prevent the veneer from sliding under pressure.

[0033] Furthermore, the support frame 4 is a telescopic structure and is arranged on the disc frame 1. The pressure plate 3 is arranged on the disc frame 1 through the support frame 4. The support frame 4 is rotatably arranged on the disc frame 1, and the rotation axis is perpendicular to the rotation axis of the disc frame 1. The base plate 2 is rotatably arranged on the disc frame 1 and the rotation axis is parallel to the moving direction of the pressure plate 3. It also includes: a connecting frame 5, the connecting frame 5 is sleeved on the telescopic joint of the support frame 4 close to the pressure plate 3; a linear drive 6, and the linear drive 6 is used to drive the connecting frame 5 to move.

[0034] In this embodiment, the carrier frame 4 is a telescopic structure for supporting the pressing plate 3 and can be rotatably arranged on the disc frame 1, and its rotation axis is perpendicular to the rotation axis of the disc frame 1. A linear drive device is set to drive the pressing plate 3 to move. At the same time, the carrier frame 4 is rotatably arranged on the disc frame 1, and its rotation axis is perpendicular to the rotation axis of the disc frame 1. The carrier frame 4 is driven to rotate by a special motor or other driving methods, and the bottom plate 2 is driven to rotate synchronously through pressure transmission. According to the actual veneer material produced, if the rotation effect of the bottom plate 2 driven by pressure transmission is weak, it can be driven synchronously by setting motors on both sides. The purpose is to make the pressing plate 3 and the bottom plate 2 rotate synchronously and drive the multi-layer veneer in the pressing space to follow the rotation while maintaining pressure, so that the glue can fully penetrate into the wood. In the traditional stacking form, the flow direction of the glue is relatively single from top to bottom. When the local glue smearing of the veneer is uneven, stacking cold pressing will only further strengthen this unevenness. In this solution, by driving the multi-layer veneer to rotate, the glue can be synchronously affected by gravity while maintaining the standard pressure, so that it can be spread more evenly between the veneers, improving the quality and stability of the product. The rotation speed of the pressing plate 3 and the bottom plate 2 needs to take into account the stability of the entire equipment. It is recommended to adjust it to a speed range of one rotation every 30-60 minutes. The specific speed can be adjusted according to the actual situation and should not be too fast to avoid damage to the veneer or equipment instability.

[0035] Furthermore, it also includes: a base 7, which is movably set on the disc frame 1 and the moving direction is parallel to the moving direction of the pressure plate 3, and the bottom plate 2 is rotatably set on the base 7 and is set on the disc frame 1 through the base 7.

[0036] In this embodiment, the base 7 provides stable support for the bottom plate 2 to ensure that the bottom plate 2 can carry multiple layers of veneers. The base 7 can move on the disc frame 1, and the moving direction is parallel to the moving direction of the pressing plate 3. In this way, when a small number of veneers need to be cold pressed, the distance that the pressing plate 3 needs to move can be reduced by moving the base 7, thereby speeding up the processing speed. In traditional cold pressing processes, the bottom plate 2 is usually fixed, which means that each time a different number of veneers are cold pressed, the pressing plate 3 needs to be moved to a predetermined position. When the number of cold pressed veneers is small, the pressing plate 3 needs to move a long distance, which will seriously affect the processing efficiency. By providing a movable base 7, the distance between the bottom plate 2 and the pressing plate 3 can be quickly adjusted according to actual needs, thereby reducing waiting time and improving work efficiency.

[0037] Furthermore, the bottom plate 2 has a placement position 201 and a plurality of mounting grooves 202, the plurality of mounting grooves 202 are arranged along the circumference of the placement position 201, and are located on the end surface of the bottom plate 2 close to the pressure plate 3; it also includes: a plurality of baffles 8, the baffles 8 are swingably arranged in the mounting grooves 202, the baffles 8 are at a certain angle with the bottom plate 2 or enter the mounting grooves 202 after swinging, and the upper end surface of the baffles 8 is flush with the upper end surface of the bottom plate 2 after the baffles 8 swing into the mounting grooves 202. Rod 9, the rod 9 is rotatably arranged on the bottom plate 2, and one end of the baffle 8 is arranged on the rod 9; gear 10, the gear 10 is arranged at both ends of the rod 9, two gears 10 and one rod 9 constitute a transmission rod group, the transmission rod group has multiple groups, and the gears 10 of the multiple transmission rod groups are meshed and connected end to end, the rod 9 is a telescopic structure, and it also includes: a connecting member 11, the two ends of the connecting member 11 are rotatably arranged at one end of two adjacent rods 9 relative to the rod 9.

[0038] In this embodiment, the bottom plate 2 has a plurality of mounting grooves 202 for placing the baffle 8. The baffle 8 is swingably arranged in the mounting groove 202. The swinging forms of the baffle 8 are as follows: 1. After the baffle 8 swings, the baffle 8 is away from the placement position 201. The baffle 8 is arranged obliquely relative to the mounting groove 202, which is used for the operator to place the multi-layer single board in the placement position 201. During the placement process, the obliquely arranged baffle 8 can play a certain guiding role, helping the operator to place the single board more conveniently. 2. After the baffle 8 swings, the baffle 8 is close to the placement position 201 and is perpendicular to the bottom plate 2, which is used to push the single board that has been placed for further position adjustment, and can push the single board that has been partially offset to the inside to ensure the accuracy of the single board position. 3. After the baffle 8 swings, it enters the mounting groove 202, and the upper end surface of the baffle 8 is flush with the upper end surface of the bottom plate 2. Its function is to fill the mounting groove 202 to avoid the vacancy of the notch of the mounting groove 202 affecting the quality of the single board surface during the cold pressing process. In order to minimize the degree of vacancy on the upper end surface of the base plate 2 after the baffle 8 swings into the installation groove 202, this solution adopts a solution in which a receiving groove 203 matching the end of the baffle 8 is set inside the base plate 2. After the baffle 8 moves, the arc-shaped portion can enter the receiving groove 203, thereby effectively avoiding the end surface gap that may be caused by the arc-shaped portion.

[0039] When faced with single boards of different sizes, the position of the baffle 8 can be adjusted through a linear drive 6, such as an electric push rod, combined with a telescopic structure rod 9. Preferably, the square placement position 201 (the single board is usually square) is maintained, with the positions of the rods 9 on both sides fixed. It is only necessary to set linear drives 6 for the rods 9 on both sides of the square that are perpendicular to each other to achieve the adjustment of the position of the overall baffle 8, thereby adapting to single boards of different sizes.

[0040] When the single board is changed from a small size to a large size, the electric push rod first pushes the rod 9 to move to the matching position, and further drives one of the rods 9 to rotate by rotating the driving member, and transmits the rotation to other rods 9 through the gear 10, thereby driving all the baffles 8 to swing synchronously. After the single board is placed, the baffle 8 is driven to swing further, so that the baffle 8 enters the installation groove 202. At this time, there will be a part of the vacancy in the installation groove 202, and the electric push rod is required to pull the rod 9 to move, driving the baffle 8 to fill the vacancy.

[0041] Preferably, considering that veneers are usually transported by forklift during placement, the width of the baffle 8 can be smaller than the width between adjacent fork bars of the forklift, and the interval between two adjacent baffles 8 is larger than the width of the fork bars of the forklift, so that the forklift can smoothly place the veneer on the floor and move it out directly. The function of the connecting member 11 is to keep the two gears 10 in a meshing state during the movement of the rod 9. By providing a swingable baffle 8 and an adjustable rod 9 and gear 10 transmission mechanism, veneers of different sizes can be flexibly adapted while ensuring the accuracy and flatness of the veneer placement. This design not only improves the flexibility and efficiency of the cold pressing process, but also ensures the quality of the final product.

[0042] Furthermore, the invention also includes: the bottom plate 2 is a split structure, and has an installation space inside, and the transmission rod groups are arranged in the installation space. The sound insulation pad is arranged on the side wall of the installation space.

[0043] In this embodiment, the base plate 2 adopts a split design, which is easy to install and maintain. The base plate 2 has an installation space inside for installing components such as a transmission rod group. The transmission rod group is arranged in the internal installation space of the base plate 2, which not only protects the transmission components, but also reduces the demand for external space. The sound insulation pad is arranged on the side wall of the installation space, which can effectively absorb the noise generated by the operation of the transmission rod group, reduce the impact on the surrounding environment, and improve the comfort of the working environment. Arranging components such as the transmission rod group inside the base plate 2 can make full use of the internal space, reduce the overall footprint of the equipment, and improve space utilization. The base plate 2 adopts a split structure, which is easy to disassemble and install, and is convenient for maintenance and replacement of components such as the internal transmission rod group. The transmission rod group is arranged inside the base plate 2, which can prevent the operator from accidentally contacting the moving parts and improve the safety of the equipment. It is worth noting that an additional support structure can be arranged inside the bottom to improve the overall strength and be competent for cold pressing operations in coordination with the pressing plate 3.

[0044] The base plate 2 is designed as a split structure and can be disassembled and assembled as needed. Sufficient space is reserved inside for installing components such as the transmission rod group and the sound insulation pad. The transmission rod group is pre-assembled and then installed as a whole in the internal installation space of the base plate 2. Ensure that all gears 10 and connectors 11 can operate normally without interference. Sound insulation pads are laid on the side walls of the internal installation space of the base plate 2, and suitable sound insulation materials such as rubber, foam plastics, etc. can be selected to ensure good sound insulation. After the installation is completed, the entire system is debugged, the operation of the transmission rod group is checked, and it is ensured that all baffles 8 can be correctly swung into place and no abnormal noise is generated. A safety check is carried out to confirm that the moving parts such as the transmission rod group will not be accidentally contacted to ensure the safety of the operator. Through the above design, not only the working efficiency and safety of the cold pressing equipment are improved, but also noise pollution is reduced and the working environment is improved. This design is particularly suitable for operating scenarios that require high precision and low noise, such as the production of precision electronic parts or small cold pressing equipment in office environments.
