Description

Technical Field

[0001] This invention relates to the field of plastic product processing technology, specifically to a suspended conveying device and its conveying method for plastic product processing. Background Technology

[0002] In the continuous processing of plastic products, such as injection molding, cooling and curing, surface coating, drying and shaping, and quality inspection and sorting, overhead conveyor systems are commonly used to achieve assembly line-style transfer operations. Overhead conveyors effectively prevent damage to product surfaces from stacking and squeezing, and avoid scratches from table contact. They are suitable for conveying and processing precision plastic parts with thin walls, irregular shapes, and high appearance requirements. The stability and protective properties of the overhead clamping directly determine the yield and appearance quality of the finished plastic products.

[0003] Most existing plastic product suspension conveyor devices adopt a fixed open hook structure, which is simple in structure and single in function. They rely solely on the hook to support the plastic products. Under conditions such as high-speed movement, start-stop braking, turning and deviating on the assembly line, the suspended plastic products are prone to large-scale shaking. When the shaking amplitude is large, the products are very likely to slip off from the hook opening and fall off, causing product damage. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a suspended conveying device and conveying method for processing plastic products, thus solving the problems mentioned in the background section.

[0007] According to the above technical solution, the long gear and the long rack mesh, the front pressure plate is used to prevent the plastic product from falling off the hook, and the side plate is used to clamp the plastic product from both sides.

[0008] According to the above technical solution, a stabilizing device is provided on the rear side of the connecting box, which is used to reduce the swaying of the hook; a supporting device is provided at the bottom of the connecting box, which is used to prevent indentations from occurring at the contact point between the plastic product and the hook.

[0009] According to the above technical solution, the stabilizing device includes: a limiting groove, which is opened inside the connecting box; a small spring is fixed at the bottom of the limiting groove; a vertical plate is fixed above the small spring; the vertical plate is slidably connected to the inner wall of the limiting groove; a lower roller is rotatably connected above the vertical plate; an L-shaped pressure rod is fixed to the side wall of the vertical plate away from the chain; the lower end of the L-shaped pressure rod is inclined; a slide rail is fixed to the side wall of the connecting box away from the chain; a counterweight is slidably connected to the inner wall of the slide rail; a horizontal spring is fixed to the inner wall of the slide rail; and the horizontal spring is fixedly connected to the counterweight.

[0010] According to the above technical solution, a moving magnet is fixed to the side wall of the counterweight, and a fixed magnet is fixed to the side wall of the slide rail. The counterweight is used to stabilize the connecting box when it shakes. The fixed magnet and the moving magnet repel each other magnetically and are used to stabilize the counterweight quickly.

[0011] According to the above technical solution, the supporting device includes: a long rod, which is fixed below the connecting box, and a supporting plate is rotatably connected to the lower end of the long rod; a pressing rod is fixed to the side of the horizontal plate near the long rod; a large torsion spring is fixed to the side wall of the supporting plate, and the large torsion spring is fixedly connected to the side wall of the long rod; the lower end of the pressing rod is arc-shaped and used to rotate the supporting plate.

[0012] According to the above technical solution, a rectangular groove is provided on the upper end face of the support plate, a trigger plate is slidably connected to the inner wall of the rectangular groove, a large spring is fixed below the trigger plate, the large spring is fixedly connected to the bottom of the rectangular groove, a stop plate is rotatably connected to the inner side wall of the rectangular groove, a small torsion spring is fixed to the side wall of the stop plate, the small torsion spring is fixedly connected to the inner side wall of the rectangular groove, and the stop plate is used to clamp the front and rear sides of the plastic product.

[0013] The present invention also provides a suspended conveying method for processing plastic products, the steps of which are as follows: Step 1: After the motor is turned on, the drive sprocket rotates, driving the chain to move, which in turn drives the driven sprocket to rotate. The chain drives the upper roller, connecting rod and fixed clamp to move, which in turn moves the connecting box and hook. Step 2: After hanging the plastic product on the hook, the hook will move the L-shaped rack downwards. The L-shaped rack will then drive the short gear, short rotating rod, and front pressure plate to flip downwards, thereby sealing the opening of the hook and preventing the plastic product from shaking out. Step 3: After hanging the plastic product on the hook, the hook will move the horizontal plate and the long toothed rack downwards. The long toothed rack will then rotate the long rotating rod and the side plate downwards to clamp the two sides of the plastic product, making the plastic product stable. Step 4: When the connecting box wobbles left and right, the vertical plate in the tilt direction moves downward. The downward movement of the vertical plate causes the counterweight to move in the opposite direction, thereby changing the position of the center of gravity and reducing the amplitude of the wobbling of the connecting box. Step 5: After the counterweight moves, the moving magnet and the stationary magnet repel each other, making the counterweight stabilize quickly; Step Six: After the horizontal plate moves downward, it drives the lower pressure rod to press down on the support plate. The support plate flips upward, so that the support plate supports the lower end of the plastic product and prevents indentations from forming at the contact point between the plastic product and the hook. Step 7: When the trigger plate is pressed down by the plastic product, the abutments on both sides flip upward, thereby clamping the front and back sides of the plastic product to prevent it from shaking.

[0014] This invention provides a suspended conveyor device for processing plastic products. It has the following advantages: 1. This invention, by setting up a connecting box, cavity, return spring, thick rod, horizontal plate, long gear, long rack, long rotating rod, side plate, short rotating rod, L-shaped rack, short gear and front pressure plate, allows the plastic product to be hung on the hook. After the hook moves the horizontal plate downward, the hook causes the front pressure plate to flip downward, sealing the opening of the hook and preventing the plastic product from falling off the hook due to shaking. After the horizontal plate moves downward, the side plates on both sides flip downward, clamping the plastic product from both sides and preventing the plastic product from shaking and causing indentations at the contact point with the hook.

[0015] 2. This invention, by setting a limiting groove, a small spring, a vertical plate, a lower roller, an L-shaped pressure bar, a slide rail, a counterweight, and a horizontal spring, ensures that during chain transport, when the connecting box shakes, the vertical plate and lower roller in the tilting direction of the connecting box move downwards, thereby causing the counterweight to move in the opposite direction of tilting. This changes the center of gravity of the connecting box, thereby reducing the amplitude of the shaking and preventing damage to adjacent plastic products caused by large shaking of the connecting box.

[0016] 3. By setting a fixed magnet and a moving magnet, the counterweight moves towards the fixed magnet along with the moving magnet during the movement of the counterweight. The moving magnet and the fixed magnet repel each other, so the counterweight moves stably and will not shake with the shaking of the connecting box. Thus, under the action of the counterweight, the connecting box is quickly stabilized, preventing the connecting box from shaking and falling off the chain.

[0017] 4. This invention, by setting up a long rod, a lowering rod, a large torsion spring, and a support plate, allows the plastic product to be placed on the hook. The horizontal plate moves downward, causing the lowering rod to press down on the support plate, which in turn flips the support plate upward. This slightly lifts the plastic product from below, reducing the pressure on the contact point between the plastic product and the hook due to gravity, and thus preventing indentations from forming on the contact point due to gravity.

[0018] 5. This invention, by setting up a rectangular groove, a trigger plate, a large spring, a small torsion spring, and a stop plate, allows the plastic product to squeeze the trigger plate after the support plate is flipped, causing the stop plates on both sides to flip upwards, thereby clamping the plastic product from the front and rear sides of the hook, preventing the plastic product from shaking back and forth after being lifted, and colliding with the hook and causing damage.

[0022] Please see Figures 1-8 One embodiment of the present invention is: a suspended conveying device for processing plastic products, comprising a bracket 1, a top frame 2, a motor 3, a drive sprocket 4, a driven sprocket 5, a connecting plate 6, a chain 7, a guide groove 8, an upper roller 9, a connecting rod 10, a fixing clamp 11, a hook 12, a connecting box 13, a cavity 14, a return spring 15, a thick rod 16, a horizontal plate 17, a long gear 18, a long rack 19, a long rotating rod 20, a side plate 21, a short rotating rod 22, an L-shaped rack 23, a short gear 24, and a front pressure plate 25; the top frame 2 is fixed above the bracket 1, the motor 3 is fixed to the inner wall of the top frame 2, the drive sprocket 4 is fixed to the output end of the motor 3, the connecting plate 6 is fixed to the inner wall of the top frame 2, the driven sprocket 5 is rotatably connected to the bottom of the connecting plate 6, the drive sprocket 4 is engaged with the chain 7, and the chain 7 is engaged with the driven sprocket 5; The guide groove 8 is located on the side wall of the top frame 2. An upper roller 9 is fitted to the inner wall of the guide groove 8. A connecting rod 10 is rotatably connected to the side wall of the upper roller 9. A fixing plate 11 is fixed below the connecting rod 10 and is fixedly connected to the chain 7. A connecting box 13 is fixed below the fixing plate 11. A cavity 14 is formed inside the connecting box 13. A return spring 15 is fixed to the top of the cavity 14. A thick rod 16 passes through the lower part of the connecting box 13 and is slidably connected at the point of penetration. The thick rod 16 is slidably connected to the inner wall of the cavity 14, and the upper part of the thick rod 16 is fixedly connected to the return spring 15. A horizontal plate 17 is fixed to the outer wall of the thick rod 16. A hook 12 is fixed to the bottom of the horizontal plate 17. An L-shaped rack 23 is fixed to the front side of the horizontal plate 17. A short rotating rod 22 is rotatably connected to the side wall of the connecting box 13. A short gear 24 is fixed to the outer wall of the short rotating rod 22. A front pressure plate 25 is fixed to the outer wall of the short rotating rod 22. The L-shaped rack 23 meshes with the short gear 24. A long rack 19 is fixed to the top of the horizontal plate 17. A long rotating rod 20 is rotatably connected to the side wall of the connecting box 13. A long gear 18 is fixed to the outer wall of the long rotating rod 20. A side plate 21 is fixed to the outer wall of the long rotating rod 20.

[0023] It is worth noting that the long gear 18 and the long rack 19 mesh, the front pressure plate 25 is used to prevent the plastic product from falling off the hook 12, and the side plate 21 is used to clamp the plastic product from both sides. By setting up the connecting box 13, cavity 14, return spring 15, thick rod 16, horizontal plate 17, long gear 18, long rack 19, long rotating rod 20, side plate 21, short rotating rod 22, L-shaped rack 23, short gear 24 and front pressure plate 25, after the plastic product is hung on the hook 12, the hook 12 drives the horizontal plate 17 to move downward, which in turn causes the front pressure plate 25 to flip downward, sealing the opening of the hook 12 and preventing the plastic product from falling off the hook 12 due to shaking. After the horizontal plate 17 moves downward, the side plates 21 on both sides flip downward, clamping the plastic product from both sides and preventing the plastic product from shaking and causing indentations at the contact point with the hook 12.

[0024] In this embodiment, during operation: After starting motor 3, motor 3 drives the drive sprocket 4 to rotate, the drive sprocket 4 drives the chain 7 to move, and the driven sprocket 5 rotates synchronously. The chain 7 drives the upper roller 9, connecting rod 10, and fixed clamping plate 11 to move. The fixed clamping plate 11 drives the connecting box 13 and hook 12 to move. After the plastic product is placed on the hook 12, the hook 12 drives the thick rod 16 to move downward, accompanied by the stretching of the return spring 15. The downward movement of the thick rod 16 drives the horizontal plate 17 to move downward, and then the horizontal plate 17 drives the L-shaped rack 23 to move downward. The L-shaped rack 23 drives the short gear 24 to rotate counterclockwise, thereby causing the short rotating rod 22 and the front pressure plate to... When the front pressure plate 25 flips downwards, the lower end of the front pressure plate 25 contacts the tip of the hook 12, and the opening of the hook 12 is closed, so that the plastic product will not fall off due to shaking. When the plastic product is lifted upwards, the return spring 15 returns to its original position, the thick rod 16 moves upwards, and the front pressure plate 25 flips upwards to open. When the horizontal plate 17 moves downwards, the horizontal plate 17 drives the long rack 19 to move downwards, so that the long gear 18 rotates clockwise, which in turn causes the long rotating rod 20 to drive the side plate 21 to flip downwards, so that the side plate 21 clamps the plastic product from both sides of the hook 12. When the plastic product is removed from the hook 12, the side plates 21 on both sides flip upwards to reset.

[0025] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, a stabilizing device is provided on the rear side of the connecting box 13. The stabilizing device is used to reduce the swaying of the hook 12. The stabilizing device includes: a limiting groove 261, a small spring 262, a vertical plate 263, a lower roller 264, an L-shaped pressure rod 265, a slide rail 266, a counterweight 267, a horizontal spring 268, a fixed magnet 269, and a movable magnet 2610. The limiting groove 261 is opened inside the connecting box 13, and a small spring 262 is fixed at the bottom of the limiting groove 261. A vertical plate 263 is fixed above the spring 262. The vertical plate 263 is slidably connected to the inner wall of the limiting groove 261. A lower roller 264 is rotatably connected above the vertical plate 263. An L-shaped pressure rod 265 is fixed to the side wall of the vertical plate 263 away from the chain 7. The lower end of the L-shaped pressure rod 265 is a slope. A slide rail 266 is fixed to the side wall of the connecting box 13 away from the chain 7. A counterweight 267 is slidably connected to the inner wall of the slide rail 266. A horizontal spring 268 is fixed to the inner wall of the slide rail 266. The horizontal spring 268 is fixedly connected to the counterweight 267.

[0026] A movable magnet 2610 is fixed to the side wall of the counterweight 267, and a fixed magnet 269 is fixed to the side wall of the slide rail 266. The counterweight 267 is used to stabilize the connecting box 13 when it shakes. The fixed magnet 269 and the movable magnet 2610 repel each other magnetically and are used to stabilize the counterweight 267 quickly. By setting a limiting groove 261, a small spring 262, a vertical plate 263, a lower roller 264, an L-shaped pressure bar 265, a slide rail 266, a counterweight 267, and a horizontal spring 268, when the connecting box 13 shakes during the transport of the chain 7, the vertical plate 263 and the lower roller 264 in the tilting direction of the connecting box 13 move downwards, thereby causing the counterweight 267 to move in the opposite direction of tilting, thus changing the center of gravity of the connecting box 13, thereby reducing the amplitude of the shaking of the connecting box 13, and preventing damage caused by collisions between adjacent plastic products due to large shaking of the connecting box 13.

[0027] By setting a fixed magnet 269 and a movable magnet 2610, during the movement of the counterweight 267, the counterweight 267 moves towards the fixed magnet 269 along with the movable magnet 2610. The movable magnet 2610 and the fixed magnet 269 repel each other, so that the counterweight 267 moves stably and will not shake with the shaking of the connecting box 13. Thus, under the action of the counterweight 267, the connecting box 13 is quickly stabilized, preventing the connecting box 13 from shaking continuously and falling off the chain 7.

[0028] A support device is provided below the connecting box 13. The support device is used to prevent indentations from forming at the contact point between the plastic product and the hook 12. The support device includes: a long rod 271, a downward pressure rod 272, a large torsion spring 273, a support plate 274, a rectangular groove 275, a trigger plate 276, a large spring 277, a small torsion spring 278, and a stop plate 279. The long rod 271 is fixed below the connecting box 13. The lower end of the long rod 271 is rotatably connected to the support plate 274. The downward pressure rod 272 is fixed to the side of the horizontal plate 17 near the long rod 271. The large torsion spring 273 is fixed to the side wall of the support plate 274. The large torsion spring 273 is fixedly connected to the side wall of the long rod 271. The lower end of the downward pressure rod 272 is arc-shaped and is used to rotate the support plate 274.

[0029] A rectangular groove 275 is provided on the upper end face of the support plate 274. A trigger plate 276 is slidably connected to the inner wall of the rectangular groove 275. A large spring 277 is fixed below the trigger plate 276. The large spring 277 is fixedly connected to the bottom of the rectangular groove 275. A stop plate 279 is rotatably connected to the inner side wall of the rectangular groove 275. A small torsion spring 278 is fixed to the side wall of the stop plate 279. The small torsion spring 278 is fixedly connected to the inner side wall of the rectangular groove 275. The stop plate 279 is used to clamp the front and rear sides of the plastic product. By setting up a long rod 271, a downward pressure rod 272, a large torsion spring 273, and a support plate 274, after the plastic product is placed on the hook 12, the horizontal plate 17 moves downward, causing the downward pressure rod 272 to press down on the support plate 274, causing the support plate 274 to flip upward, thereby slightly lifting the plastic product from below, reducing the pressure generated by gravity at the contact point between the plastic product and the hook 12, and thus preventing indentations from forming at the contact point due to gravity.

[0030] By setting up a rectangular groove 275, a trigger plate 276, a large spring 277, a small torsion spring 278, and a stop plate 279, when the support plate 274 is flipped, the plastic product squeezes the trigger plate 276, causing the stop plates 279 on both sides to flip upwards, thereby clamping the plastic product from the front and rear sides of the hook 12, preventing the plastic product from shaking back and forth after being lifted, and colliding with the hook 12 and causing damage.

[0031] Based on the above embodiment, a suspended conveying method for processing plastic products is proposed, with the following steps: Step 1: After the motor 3 is turned on, the drive sprocket 4 rotates and drives the chain 7 to move, which in turn drives the driven sprocket 5 to rotate. The chain 7 drives the upper roller 9, connecting rod 10 and fixed clamp 11 to move, which in turn drives the connecting box 13 and hook 12 to move. Step 2: After the plastic product is hung on the hook 12, the hook 12 drives the L-shaped rack 23 to move downward. The L-shaped rack 23 drives the short gear 24, the short rotating rod 22 and the front pressure plate 25 to flip downward, sealing the opening of the hook 12 to prevent the plastic product from shaking out. Step 3: After hanging the plastic product on the hook 12, the hook 12 drives the horizontal plate 17 and the long toothed rack 19 to move downwards. The long toothed rack 19 drives the long rotating rod 20 and the side plate 21 to flip downwards and clamp the two sides of the plastic product, making the plastic product stable. Step 4: When the connecting box 13 wobbles left and right, the vertical plate 263 in the tilt direction moves downward. The downward movement of the vertical plate 263 causes the counterweight 267 to move in the opposite direction, thereby changing the position of the center of gravity and reducing the amplitude of the wobbling of the connecting box 13. Step 5: After the counterweight 267 moves, the moving magnet 2610 and the fixed magnet 269 repel each other, making the counterweight 267 quickly stabilize. Step 6: After the horizontal plate 17 moves downward, it drives the pressure rod 272 to press down on the support plate 274. The support plate 274 flips upward, so that the support plate 274 supports the lower end of the plastic product and prevents the plastic product from having indentations at the contact point with the hook 12. Step 7: When the trigger plate 276 is pressed down by the plastic product, the abutment plates 279 on both sides flip upward, thereby clamping the front and rear sides of the plastic product to prevent it from shaking.

[0032] In this embodiment, during transportation of the plastic product placed on the hook 12, when the connecting box 13 shakes, the vertical plate 263 in the tilting direction of the connecting box 13 is forced to move downwards, accompanied by the compression of the small spring 262. The downward movement of the vertical plate 263 drives the L-shaped pressure rod 265 to move downwards. The inclined surface at the lower end of the L-shaped pressure rod 265 forces the side of the counterweight 267 to move in the opposite direction of the tilting direction of the connecting box 13, thereby causing the center of gravity of the connecting box 13 to shift in the opposite direction of tilting, thus reducing the shaking amplitude of the connecting box 13. During the movement of the counterweight 267, the counterweight 267 moves the movable magnet 2610 towards the fixed magnet 269. Since the movable magnet 2610 and the fixed magnet 269 have the same magnetism, they generate a repulsive force. Under the influence of the repulsive force, the counterweight 267 moves stably, thereby quickly stabilizing the connecting box 13.

[0033] When the plastic product is placed on the hook 12, the horizontal plate 17 moves the downward pressure rod 272 downward, which in turn moves the support plate 274, causing the support plate 274 to flip upward. Simultaneously, the large torsion spring 273 is compressed, causing the support plate 274 to slightly lift the plastic product, reducing the pressure at the contact point between the plastic product and the hook 12. After the plastic product is removed from the hook 12, the support plate 274 flips downward under the restoring action of the large torsion spring 273. When the support plate 274 flips upward, the bottom of the plastic product contacts the trigger plate 276, causing the trigger plate 276 to... As the large spring 277 is compressed, the trigger plate 276 moves downward and presses the end of the abutment plate 279, causing the abutment plate 279 to flip upward. With the compression of the small torsion spring 278, the abutment plates 279 on both sides clamp the front and rear sides of the plastic product. After the plastic product is removed from the hook 12, the support plate 274 flips downward under the reset action of the large torsion spring 273, and after the trigger plate 276 is separated from the plastic product, it moves upward under the reset action of the large spring 277, so that the abutment plate 279 flips downward under the reset action of the small torsion spring 278.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

9. A method for suspended conveying in plastic product processing, employing the suspended conveying device for plastic product processing as described in claim 8, characterized in that: Includes the following steps: Step 1: After turning on the motor (3), the drive sprocket (4) rotates and drives the chain (7) to move, which in turn drives the driven sprocket (5) to rotate. The chain (7) drives the upper roller (9), connecting rod (10) and fixed clamp (11) to move, which in turn drives the connecting box (13) and hook (12) to move. Step 2: After hanging the plastic product on the hook (12), the hook (12) drives the L-shaped rack (23) to move downward. The L-shaped rack (23) drives the short gear (24), short rotating rod (22) and front pressure plate (25) to flip downward, thereby sealing the opening of the hook (12) to prevent the plastic product from shaking out. Step 3: After hanging the plastic product on the hook (12), the hook (12) drives the horizontal plate (17) and the long toothed rack (19) to move downwards. The long toothed rack (19) drives the long rotating rod (20) and the side plate (21) to flip downwards to clamp the two sides of the plastic product, making the plastic product stable. Step 4: When the connecting box (13) sways left and right, the vertical plate (263) in the tilt direction moves downward. The downward movement of the vertical plate (263) causes the counterweight (267) to move in the opposite direction, changing the position of the center of gravity and reducing the amplitude of the sway of the connecting box (13). Step 5: After the counterweight (267) moves, the moving magnet (2610) and the fixed magnet (269) repel each other, making the counterweight (267) quickly stabilize; Step 6: After the horizontal plate (17) moves downward, it drives the lower pressure rod (272) to press down on the support plate (274). The support plate (274) flips upward, so that the support plate (274) supports the lower end of the plastic product and prevents the plastic product from having indentations at the contact point with the hook (12). Step 7: After the trigger plate (276) is pressed down by the plastic product, the abutments (279) on both sides flip upward, thereby clamping the front and back sides of the plastic product to prevent shaking.
