Description

Technical Field

[0001] This invention relates to the field of large-panel molding technology, specifically a horizontal large-panel molding machine for plastic foam molding. Background Technology

[0002] Plastic foam is made by adding foaming agents to plastic raw materials, causing them to expand through physical or chemical methods, forming numerous tiny pores. Plastic foam boards are sheet-like products processed from this material, widely used in building insulation, cushioning packaging, and other fields. In the production of plastic foam boards, a large-scale board machine is used to first fill pre-foamed raw material granules into a huge rectangular mold cavity. Then, high-temperature steam is introduced, causing the granules to expand a second time within the mold cavity, fusing together to form a compact and uniform giant foam block. For subsequent cutting, packaging, and storage, the formed foam boards need to be stacked. However, existing large-scale board machines have the following shortcomings: In existing technologies, when the large board machine pushes the foam board out of the molding box, the operator needs to manually support the foam board and lift it to the designated position or the conveyor rack. This not only increases the workload of the operator but also increases the operating cost of the large board machine. The conveyor rack, as an independent stacking platform, cannot be linked with the large board machine, resulting in insufficient resource utilization. During the process of pushing the foam board, there is sliding friction between the pusher block and the foam board, with a large coefficient of friction and high pushing resistance. This can easily cause scratches, and the pusher block can easily stick to debris on the foam board, which is not conducive to the conveying of the foam board.

[0003] Therefore, we propose a horizontal large-panel molding machine for plastic foam to solve the problems mentioned above. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves a lower-cost automatic stacking function through the linkage lifting mechanism. First, the first hydraulic cylinder drives the box door to rotate, which in turn drives the fixed rod and rotating wheel to rotate. This drives another set of rotating wheels and wire rope to wind up, causing the extension rod, slider, and hook to move upward, which in turn moves the support rod and rotates the support block. After the box door is fully opened, the support block is stored in the groove and the first return spring is compressed. The material plate is supported by the wire rope. When the box door is closed, the rotating shaft reverses to extend the wire rope, and the material plate moves down to the next layer of support blocks. The next layer of support blocks is prevented from tipping by the limit block. This layer of support blocks is reset under the action of the first return spring. When the hook moves down, it is blocked from rotating by the support rod. The torsion spring provides a reverse force to reset it and hook the support rod. The repeated opening and closing of the box door drives the material plate to move down layer by layer. The buffer pad cushions the material plate that moves to the bottom layer. No additional driving device is needed, realizing automatic stacking of foam boards, reducing workload and usage costs.

[0015] 2. This invention features an installation mechanism that enables faster assembly and disassembly. First, the connecting block is moved, which in turn moves the protrusion. The protrusion then compresses the second return spring, allowing the wire rope to be removed from the annular groove. The wire rope is then removed from the rotating wheel of the support frame, allowing it to be pushed away and replaced with a new material conveyor. The wire rope is then looped onto the rotating wheel, and the protrusion is pressed to compress the second return spring, allowing the wire rope to be inserted into the annular groove. The second return spring then resets the protrusion, locking it inside the annular groove, thus quickly completing the assembly and disassembly of the wire rope. This allows the material conveyor to be linked with the large-plate machine, improving the work efficiency of the operators.

[0016] 3. This invention features a pushing mechanism, achieving a more efficient pushing function. First, the foam board is pushed out by the second electric push rod. Then, the third electric push rod moves the moving plate to a suitable position. The second hydraulic cylinder drives the long plate and push block to move behind the foam board, and the third electric push rod pushes the foam board over. Subsequently, the push block, in cooperation with the second hydraulic cylinder and the third electric push rod, pushes the foam board onto the placement plate. During the pushing process, the ceramic balls directly contact the foam board to reduce resistance and scratches. The rolling motion carries debris from the foam board surface into the push block, and the ceramic balls are cleaned by a cleaning brush to keep the contact surface clean. The debris is discharged into the chip collection box through the discharge hole. The chip collection box is limited by magnetic adsorption and can be pulled out of the moving slot for removal, providing convenience for the conveying of the foam board and realizing the self-cleaning function of the ceramic balls.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A hook 210 is fixedly installed on the outer surface of the rotating rod 209. A fixing block 212 and a limiting block 215 are fixedly installed on the inner side of the column 202. A first return spring 213 is fixedly installed on one side of the outer surface of the fixing block 212. A support block 214 is fixedly installed on one end of the outer surface of the first return spring 213. A steam pipe 106 is installed at the output end of the steam generator 105. Both sides of the outer surface of the box door 104 and one side of the outer surface of the molding box 101 are connected to the output end of the steam pipe 106. A first hydraulic cylinder 109 is installed at the bottom end of the molding box 101. The output end of a hydraulic cylinder 109 is connected to the bottom end of the box door 104. A rotating shaft is fixedly installed at the rotating part of the box door 104. A fixing rod 203 is fixedly installed at both ends of the outer surface of the rotating shaft. Both the molding box 101 and the box door 104 have exhaust holes 113 on their inner sides. A second electric push rod 114 is installed on the inner side of the molding box 101. A stop block 111 is fixedly installed on the outer surface of the first electric push rod 110. A locking block 112 is fixedly installed on the top of the box door 104. The stop block 111 is locked into the inner side of the locking block 112. A rotating wheel 205 is installed on one side of the outer surface of the support frame 204 and the fixing rod 203. One set of rotating wheels 205 is fixedly installed on the outer surface of the fixing rod 203, and the other set of rotating wheels 205 is rotatably connected to the support frame 204. On the outer surface of the rotating wheel 205, a steel wire rope 206 is slidably connected. One end of the outer surface of the steel wire rope 206 is installed on the outer surface of the extension rod 207. The slider 208 is fixedly installed on both sides of the outer surface of the material plate 103. Torsion springs 211 are fixedly installed on both sides of the outer surface of the hook 210. The torsion springs 211 are sleeved on the outer surface of the rotating rod 209. The support block 214 is rotatably connected to the inner side of the column 202. Grooves are opened on both sides of the outer surface of the material plate 103 and one side of the outer surface of the column 202. The support block 214 rotatably contacts the inner side of the groove. A support rod 216 is fixedly installed on the outer surface of the support block 214. The support rod 216 is slidably connected to the inner side of the column 202 and contacts the inner side of the hook 210.

[0022] The overall effect of Embodiment 1 is as follows: it achieves a lower-cost automatic material stacking function. First, the first hydraulic cylinder 109 drives the box door 104 to rotate. The box door 104 drives the fixed rod 203 to rotate via the rotating shaft, which in turn drives the rotating wheel 205 on it to rotate. Then, the rotating wheel 205 drives another set of rotating wheels 205 and the wire rope 206 to rotate, so that the wire rope 206 is wound up. When the wire rope 206 is wound up, it drives the extension rod 207 to move upward. The extension rod 207 then drives the slider 208 and the hook 210 to move upward. The hook 210 drives the support rod 216 to move upward. The movement of the support rod 216 causes the support block 214 to rotate. When the box door 104 is fully open, the support block 214 will retract into the groove and cause the first return spring 213 to compress. At this time, the material plate 103 loses the support of the support block 214 and is supported by the wire rope 206. The four corners of the conveying rack 102 rigidly limit the material plate 103, with the gap only allowing it to slide up and down, preventing the material plate 103 from shaking or tilting. When the box door 104 is closed, the rotation... The shaft drives the fixed rod 203 and the rotating wheel 205 to rotate, thereby extending the wire rope 206. The material plate 103 loses its support and moves to the next layer of support block 214. When the material plate 103 moves, it drives the slider 208 and the hook 210 to move down. The next layer of support block 214 is prevented from tilting down by the limit block 215. Under the action of the first return spring 213, the support block 214 returns to its original position. During the movement of the hook 210, it will be blocked and rotated by the support rod 216. The torsion spring 211 will give the hook A force in the opposite direction is applied until the hook 210 passes the support rod 216. Then, the torsion spring 211 will drive the hook 210 back to its original position and hook the support rod 216. Similarly, when the box door 104 is opened again, it will drive the material plate 103 to continue to move down. The buffer pad 201 can buffer the material plate 103 that has moved to the last layer, so that the workers can complete the automatic stacking of foam boards without the need for an additional drive device. This reduces the workload of the workers and lowers the operating cost of the large board machine.

[0023] Example 2, according to Figure 1 , Figure 5 and Figure 7 As shown, the installation mechanism 3 includes an annular groove 301, which is formed on the outer surface of the extension rod 207. A storage groove 302 is formed on the outer surface of the wire rope 206. A second return spring 303 is fixedly installed at one end of the inner surface of the storage groove 302. A protrusion 304 is fixedly installed at one end of the outer surface of the second return spring 303. A connecting block 305 is fixedly installed at the top of the protrusion 304. The wire rope 206 is inserted into the inner side of the annular groove 301. The protrusion 304 is slidably connected to the inner side of the storage groove 302 and simultaneously engaged with the inner side of the annular groove 301.

[0024] The overall effect of Embodiment 2 is as follows: it achieves faster disassembly and assembly. First, the connecting block 305 is moved, which drives the protrusion 304 to move. Then, the protrusion 304 drives the second return spring 303 to compress, so that the wire rope 206 is taken out from the annular groove 301. Then, the wire rope 206 is removed from the rotating wheel 205 of the support frame 204, so that it can be pushed away and replaced with a new material conveying frame 102. Then, the wire rope 206 is put on the rotating wheel 205, and the protrusion 304 is pressed to drive the second return spring 303 to compress, so that the wire rope 206 can be inserted into the annular groove 301. Then, the second return spring 303 is used to reset and drive the protrusion 304 to lock in the inner side of the annular groove 301, thereby quickly completing the disassembly and assembly of the wire rope 206, enabling the material conveying frame 102 to be linked with the large plate machine, and improving the work efficiency of the staff.

[0025] Example 3, according to Figure 2 , Figure 8-10 As shown, the feeding mechanism 4 includes a third electric push rod 401, which is mounted on the top of the forming box 101. A movable plate 403 is mounted on the output end of the third electric push rod 401. A placement frame 402 is fixedly mounted on the top of the forming box 101. The movable plate 403 is slidably connected to the outer surface of the placement frame 402. A second hydraulic cylinder 404 is mounted on the top of the movable plate 403. A long plate 405 is mounted on the output end of the second hydraulic cylinder 404. A push block 406 is fixedly mounted on the bottom end of the long plate 405. A shaft 407 is fixedly mounted on the inner side of the push block 406. The cleaning brush 409 and two sets of push blocks 406 are symmetrically distributed on the left and right, each occupying one-quarter of the rear end face area of ​​the foam board. The outer surface of the shaft 407 is rotatably connected to the ceramic ball 408. The surface of the cleaning brush 409 is in contact with the surface of the ceramic ball 408. The surfaces of the push blocks 406 and the cleaning brush 409 are both provided with discharge holes 410. The outer surface of the push block 406 is provided with a moving groove 411. The inner side of the moving groove 411 is slidably connected to the chip collection box 412. The chip collection box 412 and the outer surface of the push block 406 are both equipped with magnetic blocks 413. The two sets of magnetic blocks 413 attract each other.

[0026] The overall effect of embodiment 3 is as follows: it achieves a more efficient pushing function. First, the foam board is pushed out of the molding box 101 by the second electric push rod 114. Then, the moving plate 403 is moved on the placement rack 402 by the third electric push rod 401. After it moves to the appropriate position, the long plate 405 is moved by the second hydraulic cylinder 404. Then, the long plate 405 moves the push block 406 to the back of the foam board. Then, the third electric push rod 401 moves the push block 406 to push the foam board down. At this time, the foam board will be laid flat on the box door 104. It only needs to move a small distance to directly contact the top of the placement plate 103 and the sides of the four corners of the conveying rack 102. The four corners of the conveying rack 102 and the column 202 limit the movement path of the foam board. Then, the second hydraulic cylinder 404 moves the push block 406 to the appropriate position. Then, the third electric push rod 401 moves the push block 406 to push the foam board down. The foam board is pushed onto the material placement plate 103, while the push blocks 406 on the left and right sides apply force to the foam board simultaneously and symmetrically to avoid uneven load caused by unilateral push. During the pushing process, the ceramic ball bearings 408 directly contact the foam board, which can reduce pushing resistance and scratches. Since there will be residual debris on the surface of the foam board, the ceramic ball bearings 408 will carry the debris into the push block 406 when rolling. At the same time, the cleaning brush 409 will clean the surface of the ceramic ball bearings 408, so that the contact surface between the ceramic ball bearings 408 and the foam board is always kept clean. The debris will be discharged into the chip collection box 412 through the discharge hole 410. When it is necessary to remove the chip collection box 412, the chip collection box 412 can be pulled out from the moving groove 411 to separate the two sets of magnetic blocks 413. Conversely, the adsorption between the two sets of magnetic blocks 413 can be used to limit the chip collection box 412, which provides convenience for the conveying of the foam board and realizes the self-cleaning function of the ceramic ball bearings 408.

[0027] The working principle of the entire equipment is as follows: During the operation of the large-plate machine, raw materials are first fed into the forming box 101 through the feeding hopper 108 and feeding pipe 107. Then, high-temperature steam is discharged into the forming box 101 through the steam generator 105 and steam pipe 106 and exhaust port 113, causing the raw materials to expand secondaryly in the forming box 101 and fuse together to form a compact and uniform foam board. Next, the first electric push rod 110 drives the stop block 111 away from the jamming block 112, and the first hydraulic cylinder 109 drives the box door 104 to rotate. The box door 104 drives the fixed rod 203 to rotate through the rotating shaft, which in turn drives the rotating wheel 205 on it to rotate. Subsequently, the rotating wheel 205 drives another set of rotating wheels 205 and wire rope 206 to rotate. The wire rope 206 is wound up, and the extension rod 207 is moved upward through the wire rope 206. Then, the extension rod 207 moves the slider 208 and hook 210 upward through the extension rod 207. The hook 210 moves the support rod 216 upward through the hook 210. The movement of the support rod 216 causes the support block 214 to rotate. As the box door 104 is fully opened, the support block 214 is retracted into the groove. The support block 214 compresses the first return spring 213, causing the material plate 103 to lose the support of the support block 214. At this time, the material plate 103 is supported by the wire rope 206, while the four corners of the conveying frame 102 rigidly limit the material plate 103. The gap is only enough to allow it to slide up and down, preventing the material plate 103 from shaking or tilting. The foam board is pushed out of the molding box 101 by the second electric push rod 114, and the moving plate 403 is moved on the placement rack 402 by the third electric push rod 401. After it is moved to the appropriate position, the long plate 405 is moved by the second hydraulic cylinder 404. Then, the long plate 405 moves the push block 406 to the back of the foam board, and the push block 406 is pushed down by the third electric push rod 401. At this time, the foam board will be laid flat on the box door 104. It only needs to move a short distance to directly contact the top of the placement plate 103 and the sides of the four corners of the conveying rack 102. The four corners of the conveying rack 102 and the column 202 limit the movement path of the foam board. Then, the push block 406 is moved to the appropriate position by the second hydraulic cylinder 404. The foam board is positioned and pushed onto the placement plate 103 by the push block 406 driven by the third electric push rod 401. The push blocks 406 on the left and right sides apply force to the foam board simultaneously and symmetrically to avoid uneven load caused by unilateral pushing force. During the pushing process, the ceramic balls 408 directly contact the foam board, reducing pushing resistance and scratches. If there are debris residues on the surface of the foam board, the rolling of the ceramic balls 408 can carry the debris into the push block 406. The cleaning brush 409 cleans the surface of the ceramic balls 408, keeping the contact surface between the ceramic balls 408 and the foam board clean. The debris is discharged into the chip collection box 412 through the discharge hole 410. When it is necessary to remove the chip collection box 412, it can be pulled out from the moving groove 411.The two sets of magnetic blocks 413 are separated, and conversely, the adsorption between the two sets of magnetic blocks 413 can limit the chip collection box 412, providing convenience for the conveying of foam boards and realizing the self-cleaning function of ceramic balls 408. When the box door 104 is closed, the rotating shaft will drive the fixed rod 203 and the rotating wheel 205 to rotate, thereby driving the steel wire rope 206 to extend, causing the material plate 103 to lose support and move to the next layer of support block 214. The material plate 103 drives the slider 208 and the hook 210 to move downward. The next layer of support block 214 is prevented from tilting downwards by limiting block 215. This layer of support block 214 is then moved back to its original position by the reset spring 213. During the movement of the hook 210, it is blocked by the support rod 216 and rotates. The torsion spring 211 applies a force in the opposite direction to the hook 210 until it passes the support rod 216. Then, the torsion spring 211 drives the hook 210 to move back to its original position and hook the support rod 216. Similarly, when the box door 104 is opened again, it will drive the material plate 103 to continue to move downwards. The buffer pad 201 cushions the material plate 103 that moves to the last layer, allowing workers to automatically stack the foam boards without the need for an additional drive device. This reduces the workload of workers and lowers the operating cost of the large-board machine. When the material rack 102 is full and needs to be replaced, the connecting block 305 can be moved. The connecting block 305 drives the protrusion 304 to move, and the protrusion 304 compresses the second return spring 303, allowing the wire rope 206 to be removed from the annular groove 301. Rope 206 is removed from the pulley 205 of the support frame 204, allowing the new material conveyor 102 to be pushed away and replaced. Then, the wire rope 206 is looped onto the pulley 205, and the protrusion 304 is pressed to compress the second return spring 303, allowing the wire rope 206 to be inserted into the annular groove 301. The return of the second return spring 303 then causes the protrusion 304 to engage inside the annular groove 301, thus completing the quick assembly and disassembly of the wire rope 206. This enables the material conveyor 102 to be linked with the large conveyor, improving the work efficiency of the operators.
