Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate processing, in particular, to an efficient and energy-saving plate composite cold pressing forming machine and a cold pressing forming method. BACKGROUND

[0002] In the current plywood production technology field, 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 plywood cold pressing process usually stacks the formed plate blanks together and then places them in a cold pressing machine for cold pressing. In this process, the single board at the bottom of the stack not only bears the pressure applied by the cold pressing machine, but also bears the gravity of the single boards above it. This situation makes the single boards at the top and bottom of the stack extremely unevenly stressed. The single boards at the top mainly bear the relatively single pressure applied by the cold pressing machine, while the single boards at the bottom not only bear the pressure of the cold pressing machine, but also bear the gravity of the single boards above them. If the number of single boards is reduced, it will affect the processing efficiency, and if the number of single boards is large, it will affect the quality of the plate.

[0004] When the number of single boards is large, the uneven stress condition is likely to have a serious adverse effect on the cold pressing effect. On the one hand, it may cause the plate surface to shift, making the single boards of the plywood unable to fit closely, affecting the overall structural stability of the product. On the other hand, it may also cause cracking. Under the action of uneven pressure, the internal structure of the single board is easily damaged, resulting in cracks, greatly reducing the strength and service life of the plywood. At the same time, blistering may also occur. Uneven pressure can cause uneven distribution of adhesive, resulting in bubbles, affecting the appearance quality and use performance of the plywood. In addition, deformation is also one of the common quality problems. Due to uneven stress, the single board may be twisted, warped, and deformed, making the plywood unable to meet the specified size and shape requirements. Moreover, uneven pressure may also cause direct damage to the plate, especially for single boards with relatively weak material, which are more likely to be damaged in this adverse pressure environment, further increasing production costs and reducing production efficiency.

[0005] In summary, the series of quality problems caused by uneven stress on the upper and lower single boards in the traditional plywood cold pressing process have become an important issue that needs to be addressed in the current plywood production field. SUMMARY

[0021] Optionally, the bottom plate is a split structure, and has an installation space inside, and the transmission rod group is arranged in the installation space.

[0022] Optionally, further comprising:

[0023] Sound insulation pad, the sound insulation pad is arranged on the side wall of the installation space.

[0024] The high-efficiency energy-saving type plate composite cold pressing forming method utilizes the composite cold pressing forming machine to carry out cold pressing processing on the multi-layer single board.

[0025] The working principle and beneficial effects of the present application are as follows:

[0026] In the present application, the disc-shaped frame is rotatably arranged on the machine tool, and the rotation axis is parallel to the ground. The bottom plate is arranged on the disc-shaped frame and used for placing the multi-layer single board to be cold pressed. The pressing plate is parallel to the bottom plate 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 single board to be cold pressed on the bottom plate, and then starts the pressing plate by the driving device to move it close to the bottom plate. The bottom plate and the pressing plate cooperate to cold press the multi-layer single board.

[0027] When the pressure gradually reaches the target pressure (usually 13 atmospheres, but can be adjusted flexibly according to different materials or the number of single boards in actual application), the driving device drives the disc-shaped 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 single board in the pressing space is also perpendicular to the ground and always maintains the vertical cold pressing process. In the traditional process, the bottom single board not only bears the pressure of the pressing plate, but also bears the gravity of the upper single board, which makes the pressure of single boards of different heights significantly affected by gravity, and further causes the unbalanced force of single boards.

[0028] When the single boards are under uneven stress, the board surface may appear to be displaced, which will make the layers of the plywood unable to closely adhere to each other, 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 single board is easily damaged, producing fine cracks. These cracks will continue to expand over time, reducing the strength and service life of the plywood. At the same time, the blistering of the board may also occur. Uneven pressure will cause uneven distribution of the adhesive, forming bubbles inside the board. These bubbles not only affect the appearance quality of the plywood, but also reduce its use performance. Deformation is also one of the common quality problems. Due to uneven stress, the single board may be twisted, warped, and deformed, making the plywood unable to meet the specified size and shape requirements. Moreover, due to uneven pressure, the board may also be directly damaged, especially for some single boards with relatively fragile material, which are more likely to be damaged in this unfavorable pressure environment. This further increases the production cost and reduces the production efficiency. By vertically arranging the single boards and innovatively cold-pressing both sides, the gravitational influence between the single boards is effectively avoided, greatly improving the uniformity of the pressure, and providing a strong guarantee for producing high-quality plywood.

[0029] It should be noted that during use, the maximum number of single boards that can be placed in the pressing space can be preliminarily calculated according to the pressure formula and the gravity of the single boards, and actual operation can be performed for verification. The standard is to ensure that the single boards will not be affected by gravity and will not be displaced or fall during vertical cold pressing. If it is necessary to increase the number of single boards for cold pressing at a time, an edge fixing mechanism can be installed according to the actual situation, or the contact surface between the pressing plate, the bottom plate, and the single board can be designed to be a material with a certain friction force to increase the friction coefficient between the single board and the pressing plate and the bottom plate, preventing the single board from sliding under pressure.

DETAILED DESCRIPTION

[0037] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description only represent some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0038] In order to make the drawing simple, only the parts related to the invention are shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0039] In this paper, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting" and "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0041] Reference Figures 1-5 , an efficient energy-saving type plate composite cold pressing forming machine is proposed for cold pressing single board, which comprises: a disc type frame 1, the disc type frame 1 is rotationally arranged, and the rotation axis is parallel to the ground; a bottom plate 2, the bottom plate 2 is arranged on the disc type frame 1; a pressing plate 3, the pressing plate 3 is movably arranged on the disc type frame 1 relative to the disc type frame 1, the moving direction of the pressing plate 3 is perpendicular to the rotation axis of the disc type frame 1, the pressing plate 3 is located on one side of the bottom plate 2 and parallel to the bottom plate 2, the pressing plate 3 moves to approach or away from the bottom plate 2, and the pressing plate 3 and the bottom plate 2 form a pressing space for placing single board.

[0042] In this embodiment, the disc-shaped frame is rotatably arranged on the machine tool, and the rotation axis is parallel to the ground. The bottom plate 2 is arranged on the disc-shaped frame 1 for placing the multi-layer single boards 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-shaped frame 1. During the processing, the operator places the multi-layer single boards to be cold pressed on the bottom plate 2, and then starts the pressing plate 3 by the driving device to move close to the bottom plate 2. The bottom plate 2 and the pressing plate 3 cooperate to cold press the multi-layer single boards.

[0043] When the pressure gradually reaches the target pressure (usually 13 atmospheres, but in actual application, it can be flexibly adjusted according to different materials or the number of single boards), the driving device drives the disc-shaped 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 single boards in the pressing space are also perpendicular to the ground, and always maintain the vertical cold pressing process. In the traditional process, the bottom single board not only bears the pressure of the pressing plate 3, but also bears the gravity of the upper single board, which makes the pressure borne by single boards of different heights significantly affected by gravity, and further causes the imbalance of the force borne by the single boards.

[0044] When the single boards are not balanced, the board surface may be displaced, which will make the layers of the plywood cannot be closely attached, affecting the overall structural stability of the product. On the other hand, it may also cause cracking. Under the action of uneven pressure, the internal structure of the single board is easy to be damaged, producing fine cracks. These cracks will continue to expand over time, reducing the strength and service life of the plywood. At the same time, the blistering may also occur. Uneven pressure will cause uneven distribution of adhesive, forming bubbles inside the board. These bubbles not only affect the appearance quality of the plywood, but also reduce its use performance. Deformation is also one of the common quality problems. Due to uneven force, the single board may be twisted, warped and deformed, so that the plywood cannot meet the specified size and shape requirements. Moreover, due to uneven pressure, it may also cause direct damage to the board, especially for some single boards with relatively weak material, which are more likely to be damaged in this unfavorable pressure environment. This further increases the production cost and reduces the production efficiency. By vertically arranging the single boards and innovatively cold pressing from both sides, the influence of gravity between the single boards is effectively avoided, greatly improving the uniformity of the pressure, and providing a strong guarantee for producing high-quality plywood.

[0045] It should be noted that in use, the maximum number of single boards that can be placed in the pressing space can be calculated preliminarily according to the pressure formula and the gravity of the single board, and actual operation can be performed for verification, and the standard is to ensure that the single board does not be affected by gravity and cause partial displacement or falling of the single board during vertical cold pressing, if the number of single boards for single cold pressing needs to be increased, the edge fixing mechanism can be installed according to the actual situation or the contact surface between the pressing plate 3 and the bottom plate 2 and the single board can be designed to be a material with a certain friction to increase the friction coefficient between the single board and the pressing plate 3 and the bottom plate 2, so as to prevent the single board from sliding under the action of pressure.

[0046] Further, the carrier frame 4 is of a telescopic structure and is arranged on the disc-shaped frame 1, the pressing plate 3 is arranged on the disc-shaped frame 1 through the carrier frame 4, the carrier frame 4 is rotationally arranged on the disc-shaped frame 1, and the rotation axis is perpendicular to the rotation axis of the disc-shaped frame 1, the bottom plate 2 is rotationally arranged on the disc-shaped frame 1 and the rotation axis is parallel to the moving direction of the pressing plate 3, and further comprising: a connecting frame 5, the connecting frame 5 is sleeved on the telescopic joint of the carrier frame 4 close to the pressing plate 3; and a linear driving member 6, the linear driving member 6 is used to drive the connecting frame 5 to move.

[0047] In the embodiment, the carrier frame 4 is of a telescopic structure, is used to support the pressing plate 3, and is rotationally arranged on the disc-shaped frame 1, and the rotation axis is perpendicular to the rotation axis of the disc-shaped frame 1, a linear driving device is arranged to drive the pressing plate 3 to move, at the same time, the carrier frame 4 is rotationally arranged on the disc-shaped frame 1 and rotates synchronously with the disc-shaped frame 1, specifically, as shown in Figure 1 The disc-shaped frame 1 is provided with a rotation driving motor, the driving shaft of the rotation driving motor is in transmission connection with the carrier frame 4, is used to drive the carrier frame 4 to rotate relative to the disc-shaped frame 1, at this time, the rotation axis of the carrier frame 4 is perpendicular to the rotation axis of the disc-shaped frame 1, the carrier frame 4 drives the bottom plate 2 to rotate synchronously through the pressure transmission of the pressing plate 3, according to the material of the single board in actual production, if the rotation effect of the bottom plate 2 driven by the pressure transmission is weak, the two sides can be provided with motors and the like to drive synchronously, the purpose is to make the pressing plate 3 and the bottom plate 2 rotate synchronously and drive the multiple layers of single boards in the pressing space to rotate in the state of keeping pressure, so that the glue is fully penetrated into the wood, in the traditional stacking form, the flow direction of the glue is relatively single from top to bottom, when the single board is locally unevenly coated with glue, the stacking cold pressing only further strengthens the unevenness. In the present scheme, by driving the multiple layers of single boards to rotate, the glue can be simultaneously affected by gravity under the premise of keeping the standard pressure, so that the glue is more evenly diffused between the single boards, and the quality and stability of the product are improved. The rotation speed of the pressing plate 3 and the bottom plate 2 needs to consider the stability of the whole equipment, it is suggested to be adjusted to the speed range of rotating one round per 30-60 minutes, and the specific speed can be adjusted according to the actual situation, and it is not suitable to be too fast, so as to avoid damage to the single board or instability of the equipment.

[0048] Further, the base station 7 is movably arranged on the disc-shaped frame 1 and moves in a direction parallel to the moving direction of the pressing plate 3, and the bottom plate 2 is rotatably arranged on the base station 7 and is arranged on the disc-shaped frame 1 through the base station 7.

[0049] In the embodiment, the base station 7 provides stable support for the bottom plate 2 and ensures that the bottom plate 2 can bear multiple layers of single boards. The base station 7 can move on the disc-shaped frame 1 and moves in a direction parallel to the moving direction of the pressing plate 3. In this way, when a small number of single boards need to be cold-pressed, the base station 7 can be moved to reduce the distance that the pressing plate 3 needs to move, thereby speeding up the processing. In the traditional cold-pressing process, the bottom plate 2 is usually fixed, which means that the pressing plate 3 needs to be moved to a predetermined position every time different numbers of single boards are cold-pressed. When the number of cold-pressed single boards is small, the pressing plate 3 needs to move a long distance, which seriously affects the processing efficiency. By arranging the movable base station 7, the distance between the bottom plate 2 and the pressing plate 3 can be quickly adjusted according to actual needs, thereby reducing the waiting time and improving the work efficiency.

[0050] Further, the bottom plate 2 has a placing position 201 and a plurality of mounting grooves 202, the plurality of mounting grooves 202 are arranged along the side of the placing position 201 and are located at the end face of the bottom plate 2 close to the pressing plate 3; further comprising 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 face of the baffle 8 is flush with the upper end face of the bottom plate 2 after the baffle 8 swings into the mounting groove 202. A rod 9 is rotatably arranged on the bottom plate 2, one end of the baffle 8 is arranged on the rod 9; a gear 10 is arranged at both ends of the rod 9, and the two gears 10 and the rod 9 constitute a transmission rod group, the transmission rod group has a plurality of groups, the gears 10 of the plurality of groups of transmission rod groups are connected in series, the rod 9 is of an extension structure, and further comprising a connecting piece 11, both ends of the connecting piece 11 are rotatably arranged at one end of two adjacent rods 9 relative to the rod 9.

[0051] 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, and the swing form of the baffle 8 has three forms: 1. After the baffle 8 swings, the baffle 8 is away from the placing position 201, and the baffle 8 is arranged obliquely relative to the mounting groove 202, which is used for the operator to place the single board in the placing position 201. During the placing process, the obliquely arranged baffle 8 can play a certain guiding role to help the operator to place the single board more conveniently. 2. After the baffle 8 swings, the baffle 8 is close to the placing position 201 and perpendicular to the bottom plate 2, which is used for pushing the single board which has been placed to further adjust the position, and can push the single board which is partially deviated to the inside to ensure the accuracy of the position of the single board. 3. After the baffle 8 swings into the mounting groove 202, the upper end surface of the baffle 8 is flush with the upper end surface of the bottom plate 2, which is used to fill the mounting groove 202, so as to avoid the gap of the mounting groove 202 to cause quality influence on the surface of the single board during the cold pressing process. In order to minimize the gap of the upper end surface of the bottom plate 2 after the baffle 8 swings into the mounting groove 202, the scheme adopts the matching accommodation groove 203 arranged in the bottom plate 2, and the arc-shaped part of the baffle 8 can enter the accommodation groove 203 after moving, which can effectively avoid the end surface gap which may be generated by the arc-shaped part.

[0052] When facing different sizes of single boards, the position of the baffle 8 can be adjusted through the linear driving element 6, such as an electric push rod, combined with the telescopic rod 9. As an optimization, the positions of the rod 9 on two sides of the square placing position 201 (the single board is usually square) are fixed, and only the rod 9 on the two sides of the square perpendicular to each other needs to be adjusted through the linear driving element 6, so as to adjust the position of the whole baffle 8, thereby adapting to different sizes of single boards.

[0053] When the size of the single board changes from small to large, first of all, the electric push rod pushes the rod 9 to move to the matching position, and then drives one of the rods 9 to rotate through the rotation driving element, and transmits the rotation to the other rods 9 through the gear 10, so as to drive all the baffles 8 to swing synchronously. After the single board is placed, the baffle 8 is further swung, so that the baffle 8 enters the mounting groove 202. At this time, there will be a part of the gap in the mounting groove 202, and the electric push rod needs to pull the rod 9 to move, so as to drive the baffle 8 to fill the gap.

[0054] As a preferred, considering that the single board is usually transported by forklift during placement, the width of the baffle plate 8 can be smaller than the width between adjacent forks of the forklift, and the spacing between two adjacent baffle plates 8 is greater than the width of the forklift fork, so that the forklift can smoothly place the single board on the floor and directly move out. The function of the connecting piece 11 is to keep the two gears 10 in meshing state during the movement of the rod 9. By setting the swingable baffle plate 8 and the adjustable rod 9 and gear 10 transmission mechanism, different sizes of single boards can be flexibly adapted, while ensuring the accuracy and flatness of the single board placement. This design not only improves the flexibility and efficiency of the cold pressing process, but also ensures the quality of the final product.

[0055] Further, the bottom plate 2 is a split structure, has an installation space inside, and the transmission rod group is arranged in the installation space. The sound insulation pad is arranged on the side wall of the installation space.

[0056] In this embodiment, the bottom plate 2 adopts a split design, which is convenient for installation and maintenance. The bottom plate 2 has an installation space inside, which is used to install components such as the transmission rod group. The transmission rod group is arranged in the internal installation space of the bottom 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 bottom plate 2 can make full use of the internal space, reduce the overall floor area of the equipment, and improve the space utilization rate. The bottom plate 2 adopts a split structure, which is convenient for disassembly and installation, and facilitates the maintenance and replacement of internal components such as the transmission rod group. The transmission rod group is arranged inside the bottom 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 additional support structures can be arranged inside the bottom to improve the overall strength and be capable of performing cold pressing operation with the pressing plate 3.

[0057] The bottom plate 2 is designed in a split structure and can be disassembled and assembled as needed. There is enough space inside for the installation of the transmission rod set and sound insulation pads, etc. The transmission rod set is pre-assembled and then installed as a whole into the internal installation space of the bottom plate 2. Ensure that all gears 10 and connecting parts 11 can operate normally without interference. Lay sound insulation pads on the side walls of the internal installation space of the bottom plate 2, and choose appropriate sound insulation materials such as rubber, foam plastic, etc. to ensure good sound insulation effect. After the installation is completed, the entire system is debugged, the operation of the transmission rod set is checked, and it is ensured that all baffles 8 can be correctly swung into place without abnormal noise. Perform a safety check to confirm that the moving parts such as the transmission rod set cannot be accidentally touched, and ensure the safety of the operators. Through the above design, not only the working efficiency and safety of the cold pressing equipment are improved, but also the 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.

[0058] The high-efficiency energy-saving type plate composite cold pressing forming method uses a composite cold pressing forming machine to cold press process multi-layer single boards.
