Description

Technical Field

[0001] This invention relates to the field of plastic product conveying technology, and more particularly to a conveying device for plastic products. Background Technology

[0002] Plastic products are a general term for daily necessities and industrial products made primarily from plastics. They include products manufactured using all processes such as injection molding and vacuum forming. Plastics are a type of synthetic polymer material with plasticity.

[0003] A conveying device and method for plastic products, with announcement number CN119821999B, includes a first storage box, a second storage box, a sorting and transporting component, and a bolt sorting system. Both the first and second storage boxes are movably mounted on a linear transport platform, staggered between them. The sorting and transporting component is mounted on a circular transport platform. The bolt sorting system is mounted on a machine tool and located on one side of the sorting and transporting component, used to separately discharge bolts of varying lengths from the sorting and transporting component into the first and second storage boxes. The entire device has a high degree of automation. Compared to traditional manual conveying methods for sorting and transporting, this device reduces labor input and shortens the separation process during the simultaneous transport of plastic product shells and bolt accessories.

[0004] The above technical solution is designed for conveying small plastic products. However, for larger plastic products, they need to be flipped during transportation for comprehensive inspection and labeling. Conventional conveying equipment does not have this function, and existing equipment cannot adaptively adjust to the specifications of plastic products. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a conveying device for plastic products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A conveying device for plastic products includes a main conveying assembly, comprising: The tilting conveyor assembly is used to receive plastic products from the main conveyor assembly and can accommodate plastic products of various sizes. The flipping component, installed inside the flipping conveyor assembly, can flip plastic products that enter the flipping conveyor assembly; The telescopic conveyor assembly continues to transport plastic products and can extend and retract synchronously with the tilting conveyor assembly; The power unit provides power for the operation of the main conveyor assembly, the tilting conveyor assembly, and the telescopic conveyor assembly, and can also adapt to the extension and retraction of the tilting conveyor assembly and the telescopic conveyor assembly. The power assembly includes a power output mechanism, an intermittent power mechanism, and an adaptive linkage mechanism; the power output mechanism is connected to the main conveying assembly, the tilting conveying assembly, and the telescopic conveying assembly; the intermittent power mechanism is connected to the main conveying assembly; and the adaptive linkage mechanism is connected to the tilting conveying assembly. The flipping conveyor assembly includes a push-pull power mechanism and a plug-in telescopic mechanism, wherein the plug-in telescopic mechanism is connected to the flipping assembly; The telescopic conveying assembly includes a lever telescopic mechanism and a telescopic conveying mechanism. The lever telescopic mechanism is connected to a push-pull power mechanism; the telescopic conveying mechanism is connected to the lever telescopic mechanism.

[0007] Compared with existing technologies, this invention can simultaneously transport plastic products using both intermittent and stable conveying methods, providing a time window for flipping plastic products and avoiding disruption to the normal operation of the device. Furthermore, it allows for the flipping of plastic products of various specifications without adjusting the overall length, ensuring the stability of plastic product conveying.

[0008] Preferably, the flipping assembly includes a hydraulic cylinder assembly rotatably connected to the plug-in telescopic mechanism, a slide rod is fixed inside the plug-in telescopic mechanism, a slide sleeve is slidably installed on the slide rod, a fixed frame is rotatably connected to the slide sleeve, and two L-shaped flipping plates are fixed on the fixed frame, with the two L-shaped flipping plates passing through the plug-in telescopic mechanism; A hydraulic cylinder assembly is rotatably connected to one side of the plug-in telescopic mechanism, and the piston rod end of the hydraulic cylinder assembly is rotatably connected to one side of one of the L-shaped flip plates.

[0009] Furthermore, the slide bar is fixed to the structure connected to the central roller shaft and can move synchronously with the roller shaft. At the same time, the lower end of the hydraulic cylinder assembly is also rotatably connected to the structure connected to the central roller shaft. Two L-shaped flip plates are respectively set on both sides of the central roller shaft and can be driven by the hydraulic cylinder assembly to perform reciprocating flipping operations. During operation, the plastic product is transported onto the roller. The L-shaped flipping plate is controlled to flip, so that the bottom of the L-shaped flipping plate comes into contact with the bottom of the plastic product. At the same time, the L-shaped flipping plate moves vertically, so that the bottom of the plastic product comes into contact with the vertical plate inside the L-shaped flipping plate. As the hydraulic cylinder assembly moves, the plate that was originally vertical will move to a horizontal position, thus realizing the function of flipping the bottom of the plastic product to expose it.

[0010] Preferably, the power output mechanism includes a motor assembly and three linkage shafts. The motor assembly is installed on one side of the main conveying assembly. One of the linkage shafts of the output shaft of the motor assembly is fixedly connected, and a synchronous belt assembly is installed together among the three linkage shafts. The three linkage shafts are respectively connected to the intermittent power mechanism, the telescopic conveying mechanism, and the plug-in telescopic mechanism.

[0011] Furthermore, the motor assembly can drive the gear assembly to rotate through the first linkage shaft. The gear assembly, notched gear assembly, contact rod assembly, and double meshing linkage gear assembly enable the main conveyor assembly to move intermittently. The synchronous belt assembly consists of three pulleys and a belt fitted on the three pulleys. The belt and pulleys are equipped with toothed meshing. The toothed structure ensures the meshing effect, enabling the synchronous belt assembly to drive the three linkage shafts to rotate synchronously.

[0012] Preferably, the intermittent power mechanism includes a gear component and a notched gear component. A double-meshing linkage gear component is connected to the notched gear component. One gear in the double-meshing linkage gear component is connected to a conveying roller in the main conveying assembly. The gear component and the notched gear component mesh with each other. Abutting rods are fixed on both the gear component and the notched gear component. The abutting rod on the notched gear component is installed at the notch of the notched gear component; The gear component is connected to the power output mechanism.

[0013] Furthermore, the meshing of the gear components and the notched gear components enables the main conveying assembly to rotate. In actual production, the main conveying assembly consists of a mounting frame structure, two shafts rotatably fitted inside the mounting frame, and a conveyor belt fitted on the shafts. At the same time, plates are installed inside the mounting frame, which abut against the top of the conveyor belt, supporting the plastic products for movement. One of the shafts inside is fixedly connected to the notched gear component and can rotate intermittently with the notched gear component, so that the plastic products can be transported intermittently. The transport gaps between the plastic products allow time for subsequent plastic product flipping and corresponding plastic product inspection, labeling, and other processes.

[0014] Preferably, the adaptive linkage mechanism includes a telescopic frame assembly, on which multiple double bevel gear transmission assemblies are mounted. One of the double bevel gear transmission assemblies is connected to a linkage shaft, and the linkage shaft and the other double bevel gear transmission assemblies are connected to the plug-in telescopic mechanism.

[0015] Furthermore, the telescopic frame assembly consists of rods, tubes that slide and adjust on the rods, and rings that slide and fit on the tubes. The front ends of the rods, tubes, and rings are all fixedly connected to one of the bevel gears in the double bevel gear transmission assembly, enabling multiple bevel gears to rotate synchronously. The other bevel gear in the multiple double bevel gear transmission assemblies is fixedly connected to the second linkage shaft and a roller shaft away from the main conveying assembly, so that multiple roller shafts can rotate synchronously and in the same direction, so that the plastic material can move on the roller shaft. The two bevel gears in the double bevel gear transmission assembly are always in a meshing state to ensure stable power transmission; The telescopic frame assembly's structural design allows the double bevel gear transmission assembly to adaptively adjust to changes in the distance between multiple rollers.

[0016] Preferably, the push-pull power mechanism includes two mounting brackets installed on both sides of one end of the main conveying component. A slide plate is slidably installed on the upper end of the mounting bracket, and a push hydraulic cylinder assembly is installed on the upper end of the slide plate. A support rod is installed on the plug-in telescopic mechanism, and a bushing is slidably installed on the support rod. An inclined push rod is rotatably connected to both sides of the bushing, and the two inclined push rods are rotatably connected to the plug-in telescopic mechanism respectively. The bushing is connected to the lever telescopic mechanism; The mounting frame is connected to the telescopic conveyor mechanism.

[0017] Furthermore, the mounting bracket and fixed connection ensure overall stability, while the connection between the mounting bracket and the fixed connection provides sufficient space for movement, or a corresponding groove is opened on it so that the slide can move smoothly. At the same time, the section of the multi-section structure of the sliding bracket assembly that is closest to the main conveying assembly is fixedly connected to the mounting bracket structure inside the main conveying assembly.

[0018] Preferably, the plug-in telescopic mechanism includes two plug-in sliding frame assemblies installed on both sides of the upper end of the main conveying assembly, and multiple rollers are rotatably sleeved between the two plug-in sliding frame assemblies. The flipping assembly is connected to the rollers located in the middle. Multiple rollers are connected to an adaptive linkage mechanism; A diagonal brace is installed on one side of the plug-in sliding frame assembly, and the diagonal brace is connected to the telescopic conveying mechanism.

[0019] Furthermore, the plug-in sliding frame assembly is a multi-section structure arranged in this manner. In two adjacent sections, one end of the previous section is slidably sleeved in the next section. The two ends of the roller shaft are respectively rotatably sleeved between the corresponding two sections. The roller shaft near the main conveying assembly is connected to the second linkage shaft so that the linkage shaft can drive the roller shaft to rotate. At the same time, the adaptive linkage mechanism can drive other roller shafts to rotate synchronously.

[0020] Preferably, the lever telescopic mechanism includes a lever member, one side of which is rotatably connected to the telescopic conveying mechanism, the upper end of which is rotatably connected to a sliding frame, a support block is slidably installed in the sliding frame, the support block is connected to the push-pull power mechanism, and the lower end of which is rotatably connected to a swing rod member, which is connected to the telescopic conveying mechanism.

[0021] Furthermore, when the piston rod of the hydraulic cylinder assembly is pushed up and down, it can drive the bushing fixed to it to rise and fall. The bushing is fixedly connected to the support block, that is, the support block can follow the piston rod of the hydraulic cylinder assembly to rise and fall. When the support block descends, it can press down the sliding frame. The sliding frame can drive the lever to rotate. In actual production and manufacturing, one side of the lever is connected to the rotation of the same side. When the lever deflects, the support block and the sliding frame will rise and fall. At the same time, the sliding frame will move relative to the support block to adapt to the rotation of the lever. When the lever rotates, the rocker arm will rotate along with one end of the lever, causing the rocker arm to move horizontally. The movement of the rocker arm causes the push block to move the conveyor axis that is close to the flip conveyor assembly away from the flip conveyor assembly, so that the elastic telescopic assembly can operate synchronously, ensuring that the conveyor belt is always in a taut state and that the plastic products on the conveyor belt can move smoothly.

[0022] Preferably, the telescopic conveying mechanism includes two parts, each fixed on a push-pull power mechanism, and two conveying shafts are provided between the two parts. One of the conveying shafts is rotatably connected to the other two parts, and a conveyor belt is provided on both conveying shafts. Two push blocks are slidably mounted on opposite sides of the two push blocks, and the two ends of another conveyor shaft are rotatably connected to opposite sides of the two push blocks respectively; The bottom of the conveyor belt is in contact with a pressure roller. Both ends of the pressure roller are rotatably sleeved with fixed blocks. Both the fixed blocks and the push block are fixed with elastic telescopic components. The elastic telescopic components are connected to the same side of them.

[0023] Furthermore, two are fixed to one side of the two mounting brackets respectively to ensure that the relative position between the mounting bracket and the same side thereon is fixed. At the same time, the lower end of the diagonal brace is slidably mounted on the upper end of the same side thereon to ensure the stability of the movement of the plug-in sliding bracket assembly. When one of the conveyor shafts rotates, the other conveyor shaft also rotates by passing through the conveyor belt so that the conveyor belt can transport plastic products. In actual preparation, a movable bracket can be installed at the lower end, and corresponding movable brackets are also installed on the mounting frame and the main conveying assembly to facilitate the transfer of equipment by the staff.

[0024] Preferably, the upper ends of the telescopic conveyor assembly, the main conveyor assembly, and the flipping conveyor assembly are flush.

[0025] Furthermore, the upper ends of the conveyor belt and rollers in the main conveyor assembly are flush with the upper ends of the conveyor belt, which ensures the stability of conveying plastic products. In actual production, the upper ends of the conveyor belt and rollers in the main conveyor assembly can be provided with corresponding textures. A rubber layer is wrapped around the rollers, and the rubber layer is also provided with textures. The textures can improve the stability during transportation, and the rubber layer on the rollers can help protect the plastic products.

[0026] The beneficial effects of this invention are: 1. The power unit provides power to other corresponding components, enabling the main conveyor to move intermittently, while the tilting and telescopic conveyors operate stably. This allows plastic products on the main conveyor to intermittently enter the tilting conveyor, where they are tilted to expose the contact surface between the plastic product and the main conveyor, facilitating inspection. Simultaneously, the plastic products can enter the telescopic conveyor for further processing, allowing other corresponding procedures to be performed. The tilting conveyor can also extend to accommodate various sizes of plastic products, not just a single type. When the tilting conveyor extends, the telescopic conveyor retracts to ensure overall length stability without adjustment. 2. The power output mechanism can continuously output power to ensure the stable rotation of the tilting conveyor and the telescopic conveyor, thereby enabling the plastic products to move in a stable direction. Simultaneously, the intermittent power mechanism can connect to the main conveyor assembly, allowing the conveyor belt on the main conveyor assembly to move intermittently, causing the plastic products on it to move intermittently. When a plastic product moves onto the tilting conveyor assembly, it moves smoothly, allowing the tilting assembly to perform a sequential tilting operation on the plastic products. An adaptive linkage mechanism can transmit power from the power output mechanism to the telescopic conveyor assembly and the tilting conveyor assembly. 3. The slide bar is fixed on the structure connected to the middle roller shaft and can move synchronously with the roller shaft. At the same time, the lower end of the hydraulic cylinder assembly is also rotatably connected to the structure connected to the middle roller shaft. Two L-shaped flip plates are respectively set on both sides of the middle roller shaft and can be driven by the hydraulic cylinder assembly to perform reciprocating flipping operations. During operation, the plastic product is transported onto the roller. The L-shaped flipping plate is controlled to flip, so that the bottom of the L-shaped flipping plate comes into contact with the bottom of the plastic product. At the same time, the L-shaped flipping plate moves vertically, so that the bottom of the plastic product comes into contact with the vertical plate inside the L-shaped flipping plate. As the hydraulic cylinder assembly moves, the plate that was originally vertical will move to a horizontal position, thus realizing the function of flipping the bottom of the plastic product to expose it.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figures 1-6 A conveying device for plastic products includes a main conveying assembly 1. The flipping conveyor assembly 4 is used to receive plastic products from the main conveyor assembly 1 and can accommodate plastic products of various specifications; the flipping assembly 3 is installed inside the flipping conveyor assembly 4 and can flip the plastic products entering the flipping conveyor assembly 4. The telescopic conveyor assembly 5 continues to convey plastic products and can extend and retract synchronously with the telescopic conveyor assembly 4; Power component 2 provides power for the operation of main conveyor component 1, tilting conveyor component 4, and telescopic conveyor component 5, and can also accommodate the extension and retraction of tilting conveyor component 4 and telescopic conveyor component 5. Power component 2 can provide power for the operation of other corresponding components, enabling the main conveyor component 1 to move intermittently, while the tilting component 3 and telescopic conveyor component 5 operate stably. This allows plastic products on the main conveyor component 1 to intermittently enter the tilting conveyor component 4. While being transported on the tilting conveyor component 4, the plastic products are tilted to expose the contact surface between the plastic products and the main conveyor component 1, facilitating inspection by workers. At the same time, the plastic products can also enter the telescopic conveyor component 5 for further processing, allowing other corresponding processes to be performed. Meanwhile, the tilting conveyor component 4 can extend and retract to accommodate various specifications of plastic products, and not just a single type of plastic product. When the tilting conveyor component 4 extends, the telescopic conveyor component 5 can retract to ensure the stability of the overall length without adjustment.

[0030] The automated components in this invention all employ technical equipment, and their operation methods, operating principles, installation, and control components are all common knowledge in the field and do not need to be disclosed again. In addition, the size and specifications of the components in this application can be adaptively adjusted by the staff according to the actual situation. The moving direction in this application is that the main conveying component 1 transports the components towards the flipping conveying component 4 and the telescopic conveying component 5.

[0031] In this embodiment, the power assembly 2 includes a power output mechanism, an intermittent power mechanism, and an adaptive linkage mechanism. The power output mechanism is connected to the main conveying assembly 1, the tilting conveying assembly 4, and the telescopic conveying assembly 5. The intermittent power mechanism is connected to the main conveying assembly 1, and the adaptive linkage mechanism is connected to the tilting conveying assembly 4. The power output mechanism can continuously output power to enable the tilting conveying assembly 4 and the telescopic conveying assembly 5 to rotate stably and move in a stable direction so that the plastic products can move stably. At the same time, the intermittent power mechanism can be connected to the main conveying assembly 1 so that the conveyor belt on the main conveying assembly 1 can move intermittently, so that the plastic products on it can move intermittently. When the plastic products move onto the tilting conveying assembly 4, they can move smoothly so that the tilting assembly 3 can perform a tilting operation on the plastic products in sequence. The adaptive linkage mechanism can transmit the power of the power output mechanism to the telescopic conveying assembly 5 and the tilting conveying assembly 4.

[0032] In this embodiment, the flipping conveyor assembly 4 includes a push-pull power mechanism and a plug-in telescopic mechanism, which is connected to the flipping assembly 3. The plug-in telescopic mechanism can drive the flipping assembly 3 to move so that the middle position of the plastic product entering the flipping conveyor assembly 4 can be moved onto the flipping assembly 3, allowing the plastic product to flip. The telescopic conveyor assembly 5 includes a lever telescopic mechanism and a telescopic conveying mechanism, which is connected to the push-pull power mechanism. The push-pull power mechanism and the lever telescopic mechanism can make the extension and contraction of the flipping conveyor assembly 4 and the contraction and extension of the telescopic conveyor assembly 5 linked, which helps to maintain the stability of the overall length. The telescopic conveying mechanism is connected to the lever telescopic mechanism to ensure that the length of the telescopic conveyor assembly 5 can extend and retract synchronously with the extension and retraction of the flipping conveyor assembly 4.

[0033] In this embodiment, the flipping assembly 3 includes a hydraulic cylinder assembly 35 rotatably connected to the plug-in telescopic mechanism. A slide rod 33 is fixed inside the plug-in telescopic mechanism. A sliding sleeve 34 is slidably mounted on the slide rod 33. A fixed frame 32 is rotatably connected to the sliding sleeve 34. Two L-shaped flipping plates 31 are fixed on the fixed frame 32. The two L-shaped flipping plates 31 are disposed through the plug-in telescopic mechanism. The slide rod 33 is fixed to a structure connected to the central roller 49 and can move synchronously with the roller 49. At the same time, the lower end of the hydraulic cylinder assembly 35 is also rotatably connected to a structure connected to the central roller 49. The two L-shaped flipping plates 31 are respectively disposed on both sides of the central roller 49 and can be driven by the hydraulic cylinder assembly 35 to perform reciprocating flipping operations. During operation, the plastic product is transported onto the roller 49, and the L-shaped flip plate 31 is flipped so that the bottom of the L-shaped flip plate 31 comes into contact with the bottom of the plastic product. At the same time, the L-shaped flip plate 31 moves vertically, so that the bottom of the plastic product comes into contact with the plate that is in a vertical position inside the L-shaped flip plate 31. As the hydraulic cylinder assembly 35 moves, the plate that was originally in a vertical position will move to a horizontal position, thus realizing the function of flipping the bottom of the plastic product to expose it. A hydraulic cylinder assembly 35 is rotatably connected to one side of the plug-in telescopic mechanism. The piston rod end of the hydraulic cylinder assembly 35 is rotatably connected to one side of one of the L-shaped flip plates 31. The piston rod inside the hydraulic cylinder assembly 35 can extend and retract. The extension and retraction of the piston rod of the hydraulic cylinder assembly 35 can move one end of the L-shaped flip plate 31 so that the L-shaped flip plate 31 can be driven to flip. During the flipping process, the fixed frame 32 connected to it will rotate relative to the sliding sleeve 34 and at the same time give the sliding sleeve 34 a moving force, so that the sliding sleeve 34 moves on the sliding rod 33 to adapt to the flipping of the L-shaped flip plate 31.

[0034] In this embodiment, the power output mechanism includes a motor assembly 21 and three linkage shafts 28. The motor assembly 21 is installed on one side of the main conveying assembly 1. One of the linkage shafts 28 is fixedly connected to the output shaft of the motor assembly 21. A synchronous belt assembly 24 is installed between the three linkage shafts 28. The motor assembly 21 can drive the gear component 22 to rotate through the first linkage shaft 28. The main conveying assembly 1 can move intermittently through the gear component 22, the notched gear component 23, the abutting rod component 25, and the double-meshing linkage gear component 29. The synchronous belt assembly 24 consists of three pulleys and a belt sleeved on the three pulleys. The belt and pulleys are provided with toothed meshing. The toothed structure can ensure the meshing effect, so that the synchronous belt assembly 24 can drive the three linkage shafts 28 to rotate synchronously. The three linkage shafts 28 are respectively connected to the intermittent power mechanism, the telescopic conveying mechanism and the plug-in telescopic mechanism; the three linkage shafts 28 are respectively fixedly connected to the gear component 22, the roller shaft 49 near the main conveying component 1 and the conveying shaft 51 away from the flipping conveying component 4, which can realize the stable transmission of power.

[0035] In this embodiment, the intermittent power mechanism includes a gear component 22 and a notched gear component 23. A double-meshing linkage gear component 29 is connected to the notched gear component 23. One gear in the double-meshing linkage gear component 29 is connected to a conveying roller in the main conveying assembly 1. The double-meshing linkage gear component 29 consists of two meshing gears, and the other gear is fixedly connected to the notched gear component 23. Through the action of the gear component 22, the notched gear component 23, and the double-meshing linkage gear component 29, the conveying roller in the main conveying assembly 1 and the gear component 22 rotate in the same direction. That is, the gear component 22 and the gear connected to the conveying roller in the double-meshing linkage gear component 29 rotate in the same direction. The gear component 22 and the notched gear component 23 mesh, and the meshing of the gear component 22 and the notched gear component 23 enables the main conveying assembly 1 to rotate. In actual production, the main conveying assembly 1 consists of a mounting frame structure, two shafts rotatably sleeved in the mounting frame, and a conveyor belt sleeved on the shafts. At the same time, a plate is installed in the mounting frame, and the plate abuts against... The contact point is located at the top of the conveyor belt, which can lift and move plastic products. One of its shafts is fixedly connected to the notched gear 23, and can rotate intermittently with the notched gear 23 to allow the intermittent transport of plastic products. The transport gap between plastic products can allow time for subsequent plastic product flipping and corresponding plastic product inspection, labeling and other processes. Both the gear 22 and the notched gear 23 are fixed with abutting rods 25; the abutting rods 25 on the notched gear 23 are installed at the notch of the notched gear 23. When gear 22 and notched gear 23 mesh and rotate to the notch of notched gear 23, they cannot mesh, preventing notched gear 23 from rotating. This stops the main conveying assembly 1. Gear 22, however, continues to rotate under the action of motor assembly 21. This causes the abutment rod 25 on gear 22 to abut against the abutment rod 25 at the notch of notched gear 23, allowing the teeth on gear 22 to mesh again with the teeth on notched gear 23, thus enabling the main conveying assembly 1 to continue operating. The gear component 22 is connected to the power output mechanism; the gear component 22 is fixedly connected to the first linkage shaft 28, and the first linkage shaft 28 is fixedly connected to the output shaft of the motor assembly 21. The power output mechanism enables the gear component 22 to rotate so that the notched gear component 23 can drive the main conveying assembly 1 to perform intermittent transmission, thereby providing time intervals for the transportation, inspection and labeling of plastic products.

[0036] In this embodiment, the adaptive linkage mechanism includes a telescopic frame assembly 27, on which multiple double bevel gear transmission assemblies 26 are mounted. One of the double bevel gear transmission assemblies 26 is connected to a linkage shaft 28. The linkage shaft 28 and the other double bevel gear transmission assemblies 26 are all connected to the plug-in telescopic mechanism. The telescopic frame assembly 27 consists of a rod, a tube that is slidably adjusted on the rod, and a ring that is slidably sleeved on the tube. The front end of the rod, the tube, the front end of the tube, and the ring are all fixedly connected to one of the bevel gears in the double bevel gear transmission assembly 26, enabling the multiple bevel gears to rotate synchronously. Another bevel gear in the multiple double bevel gear transmission assemblies 26 is fixedly connected to the second linkage shaft 28 and a roller shaft 49 away from the main conveying assembly 1, so that the multiple roller shafts 49 can rotate synchronously and in the same direction, so that the plastic material can move on the roller shaft 49. The two bevel gears in the double bevel gear transmission assembly 26 are always in a meshing state to ensure stable power transmission; The structure of the telescopic frame assembly 27 enables the double bevel gear transmission assembly 26 to adapt to changes in the distance between multiple rollers 49. The linkage shaft 28 and other double bevel gear transmission components 26 are rotatably sleeved with the square tube structure inside the plug-in sliding frame assembly 41, and the connection position is located at the connection between the rod and the tube, which helps to maximize the extension and retraction of the plug-in sliding frame assembly 41 without affecting the rotation of the roller shaft 49.

[0037] In this embodiment, the push-pull power mechanism includes two mounting brackets 48 installed on both sides of one end of the main conveying assembly 1. A slide plate 47 is slidably installed on the upper end of the mounting bracket 48, and a push hydraulic cylinder assembly 46 is installed on the upper end of the slide plate 47. A support rod 45 is installed on the plug-in telescopic mechanism, and a bushing 44 is slidably installed on the support rod 45. An inclined push rod 43 is rotatably connected to both sides of the bushing 44. The two inclined push rods 43 are rotatably connected to the plug-in telescopic mechanism. In actual operation, when the push hydraulic cylinder assembly 46 can push the bushing 44 to rise, the two inclined push rods 43 on both sides will operate in a horizontal state. Through the rotation of the inclined push rods 43, the last section in the plug-in sliding frame assembly 41 can move away from the main conveying assembly 1. At the same time, the support rod 45 sleeved on the bushing 44 is fixedly connected to the section located in the middle. The support rod 45 can ensure that the section located in the middle is always in the middle position, so that the multiple rollers 49 are evenly unfolded, which can adapt to various specifications of plastic products. In this embodiment, the plug-in sliding frame assembly 41 adopts a three-section structure, and three corresponding rollers 49 are also provided. The two ends of the rollers 49 are respectively rotatably sleeved on the corresponding positions of the two plug-in sliding frame assemblies 41 on both sides. Each section of the plug-in sliding frame assembly 41 consists of a square tube and a rod fixed to the front end of the square tube. The rod on the single section close to the main conveying assembly 1 is fixedly connected to the mounting frame structure of the main conveying assembly 1. The rod of the next section is slidably installed in the square tube of the previous section. The square tube of the last section is fixedly connected to the diagonal brace 42 on the same side. Through the structural relationship between the diagonal brace 42 and 511, it can help to move with the extension of the plug-in sliding frame assembly 41, while ensuring the stability of the plug-in sliding frame assembly 41 when it moves. The bushing 44 is connected to the lever telescopic mechanism; the bushing 44 is fixedly connected to the support block 510. The lifting and lowering of the bushing 44 can drive the support block 510 to lift and lower, so that the sliding frame 59 follows and lifts and lowers, so as to provide power for the operation of the lever telescopic mechanism. The mounting frame 48 is connected to the telescopic conveyor mechanism; the mounting frame 48 and 511 are fixedly connected to ensure the overall stability. At the same time, the connection between the mounting frame 48 and 511 leaves appropriate space for the movement of 47), or a corresponding groove is opened on 511 so that the slide plate 47 can move smoothly. Meanwhile, the section of the multi-section structure of the insertable sliding frame assembly 41 that is closest to the main conveyor assembly 1 is fixedly connected to the mounting frame structure inside the main conveyor assembly 1.

[0038] In this embodiment, the telescopic mechanism includes two telescopic sliding frame assemblies 41 installed on both sides of the upper end of the main conveying assembly 1. Multiple rollers 49 are rotatably connected between the two telescopic sliding frame assemblies 41. The flipping assembly 3 is connected to the rollers 49 located in the middle. The telescopic telescopic mechanism can extend or retract under the action of the push-pull power mechanism so as to adapt to various specifications of plastic supports and enable them to flip on the flipping conveying assembly 4, which facilitates subsequent inspection or labeling operations by the staff. The flipping assembly 3 moves synchronously with the rollers 49 located in the middle and the structure in the middle of the telescopic sliding frame assembly 41 to ensure that the flipping assembly 3 can operate stably. Multiple rollers 49 are connected to an adaptive linkage mechanism; the plug-in sliding frame assembly 41 has a multi-section structure arranged in this manner, with one end of the previous section slidingly sleeved in the next section in two adjacent sections, and the two ends of the rollers 49 are respectively rotatably sleeved between the corresponding two sections, and the roller 49 near the main conveying assembly 1 is connected to the second linkage shaft 28 so that the linkage shaft 28 can drive the roller 49 to rotate, and at the same time, the adaptive linkage mechanism can drive other rollers 49 to rotate synchronously; A diagonal brace 42 is installed on one side of the plug-in sliding frame assembly 41. The diagonal brace 42 is connected to the telescopic conveying mechanism. The end of the diagonal brace 42 away from the main conveying assembly 1 is slidably installed on 511 on the same side. The diagonal brace 42 ensures the smoothness of the plug-in sliding frame assembly 41 during extension and retraction. By ensuring the smoothness of the movement of the plug-in sliding frame assembly 41, the stability of the horizontal position of the multiple rollers 49 installed on the plug-in sliding frame assembly 41 can be ensured, so as to stably carry the plastic products to move towards the telescopic conveying assembly 5.

[0039] In this embodiment, the lever telescopic mechanism includes a lever 58, one side of which is rotatably connected to the telescopic conveying mechanism. A sliding frame 59 is rotatably connected to the upper end of the lever 58, and a support block 510 is slidably installed inside the sliding frame 59. The support block 510 is connected to the push-pull power mechanism. A swing rod 57 is rotatably connected to the lower end of the lever 58, and the swing rod 57 is connected to the telescopic conveying mechanism. When the piston rod of the hydraulic cylinder assembly 46 is pushed up or down, it can drive the bushing 44 fixed thereto to rise or fall. The bushing 44 and the support... Block 510 is fixedly connected, meaning that support block 510 can move up and down with the piston rod of the hydraulic cylinder assembly 46. When support block 510 descends, it can press down sliding frame 59. Sliding frame 59 can drive lever 58 to rotate. In actual production, one side of lever 58 is rotatably connected to 511 on the same side. When lever 58 deflects, support block 510 and sliding frame 59 will move up and down. At the same time, sliding frame 59 will move relative to support block 510 to adapt to the rotation of lever 58. When the lever 58 rotates, the rocker arm 57 will rotate along with one end of the lever 58, causing the rocker arm 57 to move in a horizontal direction. The movement of the rocker arm 57 will cause the push block 56 to drive the conveyor shaft 51, which is close to the flip conveyor assembly 4, to move away from the flip conveyor assembly 4, so that the elastic telescopic assembly 53 can operate synchronously, ensuring that the conveyor belt 52 is always in a taut state and that the plastic products on the conveyor belt 52 can move smoothly. The dimensions of lever 58, swing rod 57, and the connection positions of levers 58 and 511 are calculated according to actual conditions to ensure that the telescopic conveyor assembly 5 and the tilting conveyor assembly 4 can be synchronized and adjusted according to the specifications of plastic products.

[0040] In this embodiment, the telescopic conveying mechanism includes two 511s, which are respectively fixed on the push-pull power mechanism. Two conveying shafts 51 are provided between the two 511s. One of the conveying shafts 51 is rotatably sleeved on the two 511s. A conveyor belt 52 is sleeved on both conveying shafts 51s. The two 511s are respectively fixed on one side of the two mounting brackets 48 to ensure that the relative position between the mounting bracket 48 and the 511 on the same side is fixed. At the same time, the lower end of the diagonal brace 42 is slidably installed on the upper end of the 511 on the same side, which can ensure the stability of the movement of the plug-in sliding frame assembly 41. When one of the conveying shafts 51 rotates, the other conveying shaft 51 also rotates through the conveyor belt 52 so that the conveyor belt 52 can transport plastic products. In actual preparation, a movable bracket can be installed at the lower end of 511, and corresponding movable brackets are also installed on the mounting frame 48 and the main conveying assembly 1 to facilitate the transfer of equipment by the staff. Two push blocks 56 are slidably installed on opposite sides of the two 511s, and the two ends of another conveying shaft 51 are rotatably connected to opposite sides of the two push blocks 56 respectively; the push blocks 56 enable the other conveying shaft 51 to move smoothly between the two 511s, that is, when the flip conveying assembly 4 extends, the conveying shaft 51 close to the flip conveying assembly 4 will move to adapt to the extension of the flip conveying assembly 4, which can ensure the stability of the overall length and adapt to the installation position; The bottom of the conveyor belt 52 is in contact with a pressure roller 55. Both ends of the pressure roller 55 are rotatably sleeved with fixed blocks 54. Both the fixed blocks 54 and the push block 56 are fixed with elastic telescopic components 53. The elastic telescopic components 53 are connected to 511 on the same side. The elastic telescopic components 53 are composed of a telescopic rod structure and a spring structure. The sleeve end of the telescopic rod is fixedly connected to 511, and the piston rod end of the telescopic rod is fixedly connected to the corresponding fixed block 54 or push block 56. The spring ensures that the conveyor belt 52 is always in a taut state and has corresponding support force, which can ensure that the plastic products at the upper end are fully supported so that they can move stably. When the distance between the two conveyor shafts 51 decreases, the elastic telescopic component 53 connected to the fixed block 54 will extend to ensure the tension of the conveyor belt 52. Meanwhile, one end of the conveyor shaft 51, which is away from the flipping conveyor assembly 4, is connected to the third linkage shaft 28 and can rotate under the action of the third linkage shaft 28 in order to provide power for the rotation of the conveyor belt 52. The rotation direction of the three linkage shafts 28 is always consistent to ensure the consistency of the movement direction of the main conveyor assembly 1, the tilting conveyor assembly 4, and the telescopic conveyor assembly 5.

[0041] In this embodiment, the upper ends of the telescopic conveyor assembly 5, the main conveyor assembly 1, and the flipping conveyor assembly 4 are arranged flush with each other. The upper ends of the conveyor belt, the upper ends of the roller 49, and the upper ends of the conveyor belt 52 in the main conveyor assembly 1 are arranged flush with each other, which can ensure the stability of conveying plastic products. At the same time, in actual production, the upper ends of the conveyor belt and the upper ends of the conveyor belt 52 in the main conveyor assembly 1 can be provided with corresponding textures. The roller 49 is covered with a rubber layer, and the rubber layer is also provided with textures. The textures can improve the stability during transportation, and the rubber layer on the roller 49 can help protect the plastic products.
