Description

Technical Field

[0001] This utility model relates to the field of plywood shaping, and in particular to a rapid shaping and pressurizing device for plywood semi-finished products. Background Technology

[0002] Plywood semi-finished products refer to the intermediate products of plywood that have completed the processes of veneer gluing and preliminary splicing during the production process, but have not yet been fully cured and formed. At this time, the structural stability of the board is relatively poor and further processing is required to meet the requirements of the finished product. Therefore, it is often necessary to use a pressure device to apply pressure to the plywood semi-finished products to ensure that the veneers are tightly bonded, promote the curing of the adhesive, eliminate interlayer gaps, and improve the flatness and strength of the board.

[0003] When using the relevant pressure device, the plywood semi-finished product is usually placed on the processing table, and then pressure is applied to the top of the plywood semi-finished product by a hydraulic device. This pressure is applied for a long time to make the veneers tightly bonded together. The veneers are shaped by the combined action of pressure and adhesive to make the desired plywood.

[0004] However, when using the above method, the adhesive is not fully cured when the veneers are bonded together. This often causes the two veneers to shift and misalign under pressure during the pressure application process, which affects the subsequent normal shaping and reduces the product qualification rate.

[0005] Therefore, it is necessary to provide a rapid shaping and pressurizing device for plywood semi-finished products to solve the above problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4 A rapid shaping and pressurizing device for plywood semi-finished products includes: a processing base 1, with a pressurizing mechanism 2 disposed on the top of the processing base 1; and a heating mechanism 3 located at the bottom of the pressurizing mechanism 2 for heating the plywood semi-finished products.

[0022] The limiting and fixing mechanism 4 includes a support plate 401, several fixing clamps 402, several size adjustment components 5 and several thickness adjustment components 6. The bottom of the support plate 401 is fixedly connected to the top of the processing base 1. The bottom of the several fixing clamps 402 is installed on the top of the support plate 401 through several size adjustment components 5. The several thickness adjustment components 6 are respectively installed on the side walls of the several fixing clamps 402.

[0023] The size adjustment assembly 5 includes a first adjustment groove 501, a threaded rod 502, an adjustment knob 503, and an adjustment slider 504. The first adjustment groove 501 is opened on the top of the support plate 401. The two ends of the threaded rod 502 are rotatably connected to the two ends of the first adjustment groove 501, and one end of the threaded rod 502 is fixedly connected to the adjustment knob 503 by rotating through one end of the first adjustment groove 501. The middle part of the adjustment slider 504 is rotatably connected to the side wall of the threaded rod 502 through the first threaded hole 505. The bottom of the fixed clamping plate 402 is fixedly connected to the top of the adjustment slider 504.

[0024] The thickness adjustment assembly 6 includes a second adjustment slide 601, several springs 602, a telescopic clamp 603, and a locking unit 7. The second adjustment slide 601 is formed on the side wall of the fixed clamp 402. One end of several springs 602 is symmetrically fixedly connected to the bottom of the second adjustment slide 601. The telescopic clamp 603 is slidably connected to the side wall of the second adjustment slide 601 by fitting with the second adjustment slide 601, and the bottom of the telescopic clamp 603 is fixedly connected to the other end of several springs 602. The locking unit 7 is installed on the other side of the fixed clamp 402.

[0025] The locking unit 7 includes a second threaded hole 701 and a locking screw 702. The second threaded hole 701 is opened on the other side of the fixed clamping plate 402 and is connected to the second adjusting slide groove 601. The locking screw 702 is rotatably connected to the other side of the fixed clamping plate 402 by engaging with the second threaded hole 701.

[0026] In the specific implementation process, firstly, according to the size of the plywood semi-finished product, the adjusting knob 503 is manually rotated to cause the connected threaded rod 502 to rotate within the first adjusting groove 501. The rotation of the threaded rod 502 within the first adjusting groove 501 causes the adjusting slider 504, connected through the first threaded hole 505, to slide on the threaded rod 502 under the constraint of the first adjusting groove 501. The sliding movement of the adjusting slider 504 on the threaded rod 502 causes the connected fixing clamp 402 to move and open at the top of the support plate 401. At this point, the plywood semi-finished product is placed on the support plate 401. Similarly, by rotating the adjusting knob 503 in the opposite direction, the fixing clamp 402 moves and closes at the top of the support plate 401. The closing of the fixing clamp 402 clamps and fixes the placed plywood semi-finished product. Based on the dimensions and thickness of the plywood semi-finished product, the telescopic clamp 603 is manually pulled upwards, causing it to slide upwards through the second adjusting groove 601 on the side wall of the fixed clamp 402 and stretch the spring 602. Then, the locking screw 702 is manually rotated, allowing it to rotate inwards through the second threaded hole 701 on the side wall of the fixed clamp 402. The locking screw 702 then abuts against the side wall of the telescopic clamp 603, thus limiting and fixing the extended telescopic clamp 603 after adjustment. At this time, the fixed clamp 402 and the telescopic clamp 603 can clamp and limit the plywood semi-finished product. This allows for the clamping and limiting of plywood semi-finished products of different sizes and thicknesses according to usage needs, thereby preventing the plywood semi-finished product from shifting or misaligning under force, effectively facilitating subsequent normal pressure shaping, and improving the product qualification rate.

[0027] It should be noted that, in order to avoid the fixed clamping plate 402 and the extended telescopic clamping plate 603 affecting normal pressurization, the height adjustment of the fixed clamping plate 402 and the extended telescopic clamping plate 603 must always be lower than the height of the upper veneer. After pressurization and shaping are completed, the locking screw 702 is rotated to make it rotate outward through the second threaded hole 701 on the side wall of the fixed clamping plate 402. By rotating the locking screw 702 outward, the contact with the telescopic clamping plate 603 can be released. At this time, the spring 602 provides a reaction force to make the telescopic clamping plate 603 spring back and retract into the second adjustment groove 601. Then, it can be adjusted and pressurized according to the size and thickness of the plywood semi-finished product.

[0028] refer to Figure 4As shown, the pressurizing mechanism 2 includes several support rods 201, a fixed plate 202, a hydraulic cylinder 203, and a pressure plate 204. The bottoms of the several support rods 201 are symmetrically fixedly connected to the top of the processing base 1. The fixed plate 202 is fixedly connected to the top of the several support rods 201. The hydraulic cylinder 203 is fixedly connected to the middle of the fixed plate 202. The top of the pressure plate 204 is fixedly connected to the output end of the hydraulic cylinder 203.

[0029] The heating mechanism 3 includes a heat-conducting copper plate 301 and several heating wires 302. The top of the heat-conducting copper plate 301 is fixedly connected to the bottom of the pressure plate 204, and the several heating wires 302 are evenly distributed and fixedly connected inside the heat-conducting copper plate 301.

[0030] Based on the above embodiments, after the plywood semi-finished product is clamped and fixed, the hydraulic cylinder 203, supported and fixed by the support rod 201 and the fixing plate 202, is activated to provide force to drive the pressure plate 204 connected to it to move downward. The downward movement of the pressure plate 204 applies pressure to the clamped and fixed plywood semi-finished product for shaping. Simultaneously, the downward movement of the pressure plate 204 causes the heat-conducting copper plate 301 to move downward and adhere to the surface of the plywood semi-finished product. When the heating wire 302 is energized, heat is generated. The heat generated by the heating wire 302 is then conducted to the plywood semi-finished product that is bonded to it through the heat-conducting copper plate 301, thereby heating the plywood semi-finished product. The heating of the plywood semi-finished product accelerates the curing of the adhesive. This allows for the simultaneous pressing and shaping of the plywood semi-finished product according to the needs of use, while simultaneously heating it, thus effectively accelerating the curing rate of the adhesive and improving the shaping efficiency.

[0031] The working principle of the plywood semi-finished product rapid shaping and pressurizing device provided by this utility model is as follows: In use, firstly, according to the size of the plywood semi-finished product, manually rotate the adjusting knob 503 to cause the connected threaded rod 502 to rotate within the first adjusting groove 501. The rotation of the threaded rod 502 within the first adjusting groove 501 causes the adjusting slider 504, connected through the first threaded hole 505, to slide on the threaded rod 502 under the limit of the first adjusting groove 501. The sliding movement of the adjusting slider 504 on the threaded rod 502 causes the connected fixing clamp 402 to move and open at the top of the support plate 401. At this time, the plywood semi-finished product is placed... Similarly, by rotating the adjusting knob 503 in the opposite direction on the support plate 401, the fixing clamp 402 can be moved and closed at the top of the support plate 401 under force. The movement and closure of the fixing clamp 402 can clamp and limit the placement of the plywood semi-finished product. At the same time, according to the size and thickness of the plywood semi-finished product, by manually pulling up the telescopic clamp 603, it is forced to slide upward through the second adjusting groove 601 on the side wall of the fixing clamp 402 and stretch the spring 602. Then, by manually rotating the locking screw 702, it can be rotated inward through the second threaded hole 701 on the side wall of the fixing clamp 402. The rotation of the locking screw 702 inward can abut against the side wall of the telescopic clamp 603, thereby allowing for adjustment. After the holiday, the telescopic clamp 603 extends and is fixed in place. At this time, the plywood semi-finished product can be clamped and fixed by the fixed clamp 402 in conjunction with the telescopic clamp 603. This effectively allows for the clamping and fixing of plywood semi-finished products of different sizes and thicknesses according to usage needs, thereby preventing the plywood semi-finished product from shifting or misaligning under force. This effectively facilitates subsequent normal pressure shaping and improves the product qualification rate. Secondly, after the plywood semi-finished product is clamped and fixed, the hydraulic cylinder 203, which is supported and fixed by the support rod 201 and the fixed plate 202, is activated. This provides force to drive the pressure plate 204 connected to it to move downward under force. The pressure plate 204 moves downward, allowing pressure to be applied to the plywood semi-finished product that is clamped and fixed, thus shaping it. Simultaneously, the downward movement of the pressure plate 204 causes the heat-conducting copper plate 301 to be forced downward and adhere to the surface of the plywood semi-finished product. At this point, the heating wire 302 is energized, generating heat. This heat is then conducted through the heat-conducting copper plate 301 to the plywood semi-finished product, heating it and accelerating the curing of the adhesive. This method effectively allows for simultaneous pressure shaping and heating of the plywood semi-finished product according to usage needs, thereby accelerating the curing rate of the adhesive and improving shaping efficiency.
