Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and in particular to a conveying device for stacking and arranging plastic products. Background Technology

[0002] Plastic products are a general term for daily and industrial products made from plastic as the main raw material through processes such as injection molding and vacuum forming. Among them, plastic lunch boxes are one of the commonly used plastic products in daily life, with many advantages such as low cost, good sealing, and easy portability. Stacking and conveying plastic lunch boxes is a common material handling process in the catering, food processing, and takeaway industries.

[0003] For example, Chinese patent CN221499832U discloses a plastic lunch box stacking device. When the device is working, it moves the device to the vicinity of the conveyor belt, thereby enabling the automatic picking and stacking of plastic lunch boxes, improving the production efficiency of plastic lunch boxes and meeting people's needs. At the same time, the overall height of the device can be manually adjusted, making the device suitable for picking and stacking plastic lunch boxes on conveyor belts of different heights, thus expanding the applicability of the device. Existing lunchbox stacking and conveying equipment uses negative gas pressure to extract plastic lunchboxes one by one for stacking. However, in actual operation, the equipment requires frequent stops to ensure extraction accuracy. This frequent start-stop operation negatively impacts the transport efficiency of the tableware. Furthermore, because the extraction device is fixed in position, it requires a high spacing between plastic tableware. Inconsistent spacing between lunchboxes can prevent accurate extraction, affecting the stacking and conveying accuracy. Additionally, the stacked lunchboxes may tip over due to inertia at the moment the conveyor belt starts, negatively impacting the transport stability. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1.

[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.

[0020] Please see Figures 1 to 9 The present invention provides a technical solution: A plastic product stacking and conveying device includes a first conveyor 11 and a second conveyor 13 for conveying lunch boxes 15. The first conveyor 11 has a side plate 12 on its outer side and an adjustment component on its inner side. The adjustment component includes a movable shaft 36 fixedly connected to the inner surface of the side plate 12. A material support plate 35 is rotatably connected to the outer surface of the movable shaft 36. A displacement groove 40 is embedded in the inner side of the material support plate 35. A displacement plate 39 is slidably connected to the inner side of the displacement groove 40. The material support plate 35 and the displacement plate 39 are used to guide the conveying of the lunch box 15. A support part is provided between the two sets of the first side plates 12. The first side plate 12 supports an electric push rod 34 through the support part. A hinge part is provided on the upper side of the electric push rod 34. The upper end of the electric push rod 34 is hinged to the lower side of the material support plate 35 through the hinge part.

[0021] The support includes a support shaft 32 fixedly connected to the inner surface of the side plate 12. A hinge seat 33 is rotatably connected to the outer surface of the support shaft 32. The upper side of the hinge seat 33 is fixedly connected to an electric push rod 34. A traction belt 42 is fixedly connected to the inner surface of the displacement groove 40. The side of the traction belt 42 away from the displacement groove 40 is fixedly connected to a displacement plate 39. The traction belt 42 is made of an elastic material.

[0022] The hinged part includes a guide groove 41 embedded in the lower outer surface of the material support plate 35. A guide block 44 is slidably connected to the inner side of the guide groove 41. A universal joint 43 is hinged to the lower outer surface of the guide block 44. The lower end of the universal joint 43 is threadedly connected to the electric push rod 34. A guide plate 16 is fixedly connected to the upper outer surface of the material support plate 35. There are two sets of guide plates 16, which are symmetrically distributed. The outer surface of the guide plate 16 is arc-shaped.

[0023] By adopting the above technical solution, during the processing and conveying of plastic lunch boxes 15, the finished lunch boxes 15 need to be stacked to reduce the volume of subsequent packaging and transportation. When the conveying device is working, conveyor 11 transports the processed lunch boxes 15 one by one. At this time, the conveying device controls conveyor 2 13 to stop moving. At this time, the lunch boxes 15 move to the upper side of the support plate 35 under the drive of conveyor 11. Under the action of inertia, the lunch boxes 15 slide down the surface of the support plate 35 to the upper side of conveyor 2 13. As the number of lunch boxes 15 on the upper side of conveyor 2 13 continues to increase, the stacking height of the lunch boxes 15 will also gradually increase. In order to adjust the falling position of the lunch boxes 15 according to the stacking height, an adjustment component is set. The first plate 12 provides rotatable support for the material support plate 35 via the movable shaft 36, allowing the material support plate 35 to rotate around the movable shaft 36 as a fulcrum. The first side plate 12 provides rotatable support for the hinge seat 33 via the support rod. Under the guidance of the hinge seat 33, the tilt angle of the electric push rod 34 can be flexibly adjusted. The electric push rod 34 provides hinge support for the guide block 44 via the universal joint 43. Under the lifting action of the guide block 44, the position of the material support plate 35 can remain stable, thus providing a stable guiding effect for the lunch box 15. The guide plate 16 on the upper side of the material support plate 35 contacts the outer surface of the lunch box 15, which can position the lunch box 15 and thus keep the discharging position of the lunch box 15 accurate. During the stacking of lunch boxes 15, when the number of lunch boxes 15 on the upper side of conveyor 2 13 is small, the electric push rod 34 is retracted. At this time, the gap between the material support plate 35 and the support rod is the smallest. The material support plate 35 is installed on the displacement plate 39 through the displacement groove 40. When the material support plate 35 is in an inclined state, the displacement plate 39 slides outward of the displacement groove 40 under its own weight. With the material support plate 35 and the displacement plate 39 working together, the lunch boxes 15 can be accurately transported to the upper side of conveyor 2 13. As the number of lunch boxes 15 stacked increases, the stacking height of the lunch boxes 15 will gradually increase, and the falling distance of the lunch boxes 15 will decrease accordingly. At this time, the electric push rod 34 gradually extends outward. The electric push rod 34 is guided by the guide block 44 and the guide... The groove 41 can push the material support plate 35, thereby gradually increasing the distance between the material support plate 35 and the support rod. At this time, the angle between the material support plate 35 and the horizontal direction will gradually decrease. Under the elastic force of the traction belt 42, the displacement plate 39 gradually moves into the displacement groove 40. When the inertia of the lunch box 15 remains constant, the angle of the material support plate 35 will also change accordingly to match the height of the lunch box 15, so that the lunch box 15 can accurately slide to the corresponding position, thereby effectively improving the stacking accuracy of the lunch box 15. At the same time, it can also reduce the impact of inconsistent spacing of the lunch boxes 15 on the stacking accuracy on the upper side of the conveyor 11, thereby effectively improving the stability and reliability of the lunch box 15 during the conveying process.

[0024] Specifically, such as Figure 4 , Figure 7 and Figure 8 As shown, a guide component is provided on the upper side of the material tray 35. The guide component includes an installation groove 37 embedded in the outer surface of the upper end of the material tray 35. A ball bearing 38 is rotatably connected to the inner side of the installation groove 37. The upper side of the outer surface of the ball bearing 38 is in rotatable contact with the lower side of the food container 15. The ball bearing 38 consists of several groups and is distributed in a parallel array.

[0025] The upper outer surface of the displacement plate 39 is embedded with a storage groove 45. A mounting base 46 is slidably connected to the inner side of the storage groove 45. A spring 48 is fixedly connected to the lower outer surface of the mounting base 46. The side of the spring 48 away from the mounting base 46 is fixedly connected to the inner surface of the storage groove 45. A ball bearing 47 is rotatably connected to the upper outer surface of the mounting base 46. The upper surface of the outer surface of the ball bearing 47 contacts the upper surface of the inner surface of the displacement groove 40.

[0026] By adopting the above technical solution, a guide component is set up to make the movement of the lunch box 15 more stable and improve the conveying accuracy. The material support plate 35 supports the rotation of the first ball 38 through the mounting groove 37, and the displacement plate 39 supports the sliding support of the mounting seat 46 through the storage groove 45. The spring 48 inside the storage groove 45 applies a certain elastic force to the mounting seat 46. The mounting seat 46 is used to support the rotation of the second ball 47. When the displacement plate 39 is inside the storage groove 45, the second ball 47 is in contact with the inner surface of the displacement groove 40. When the displacement plate 39 moves to the outside of the displacement groove 40, the mounting seat 46 is in the elastic seat of the spring 48. Extending to the outside of the storage slot 45, the mounting base 46 will drive the second ball 47 to move upward, thereby moving part of the surface of the second ball 47 to the upper side of the displacement plate 39. When the lunch box 15 moves to the upper side of the material support plate 35 and the displacement plate 39, the lower surface of the lunch box 15 will contact the outer surface of the first ball 38 and the second ball 47. The rotation of the first ball 38 and the second ball 47 can reduce the friction during the movement of the lunch box 15 to a certain extent, thereby making the movement of the lunch box 15 more stable. While reducing the wear of the plastic lunch box 15, it can also improve the conveying accuracy of the lunch box 15 to a certain extent.

[0027] Specifically, such as Figure 4 and Figure 9 As shown, a side plate 2 14 for supporting and lifting the conveyor 2 13 is provided on the outside of the conveyor 2 13. A support plate 20 is fixedly connected to the upper outer surface of the side plate 2 14. A positioning assembly is provided on the upper side of the conveyor 2 13. The positioning assembly includes a telescopic rod 21 fixedly connected to the left outer surface of the support plate 20. A positioning plate 17 is fixedly connected to the left end of the telescopic rod 21. The positioning plate 17 corresponds to the position of the conveyor 1 11.

[0028] A rotating groove 22 is embedded in the rear side of the outer surface of the positioning plate 17. A rotating shaft 23 is fixedly connected to the inner surface of the rotating groove 22. A movable seat 24 is rotatably connected to the outer surface of the rotating shaft 23. A baffle 18 is fixedly connected to the outer surface of the movable seat 24. The baffle 18 is perpendicular to the positioning plate 17. The outer surfaces of both the baffle 18 and the positioning plate 17 are in contact with the outer side of the lunch box 15.

[0029] By adopting the above technical solution, the second side plate 14 is used to support the support plate 20, and the support plate 20 fixes the telescopic rod 21. The telescopic rod 21 can push the positioning plate 17. When the lunch box 15 moves to the upper side of the second conveyor 13, a part of the outer surface of the lunch box 15 will contact the left side of the positioning plate 17. The positioning plate 17 can buffer the inertia of the lunch box 15 and position the lunch box 15, thereby keeping the position of the lunch box 15 stable. The position of the positioning plate 17 can be adjusted by the telescopic rod 21, so that the position of the positioning plate 17 can be finely adjusted according to the specifications of the lunch box 15, thereby further improving the conveying device. The positioning plate 17 is fixedly installed on the rotating shaft 23 through the rotating groove 22. The movable seat 24 can rotate around the rotating shaft 23 as the fulcrum. The rotating shaft 23 rotates around the baffle 18 through the movable seat 24. The baffle 18 and the positioning plate 17 are kept perpendicular to each other, which can play a positioning role on the rear side of the lunch box 15. When the lunch boxes 15 on the upper side of the second conveyor 13 are stacked to a predetermined number, the operator controls the second conveyor 13 to start moving. At the moment the second conveyor 13 starts, the baffle 18 can play a positioning role on the lunch box 15, thereby reducing the risk of the lunch box 15 tilting backward due to inertia, and further improving the conveying stability of the lunch box 15.

[0030] Specifically, such as Figure 4 , Figure 5 and Figure 9 As shown, a recycling assembly is provided on the outer side of the positioning plate 17. The recycling assembly includes a second fixing plate 26 fixedly connected to the outer surface of the right end of the positioning plate 17. The second fixing plate 26 is fixedly connected to the outer surface of the rear end of the baffle 18. A recycling plate 27 is fixedly connected between the first fixing plate 25 and the second fixing plate 26.

[0031] The outer surface of the recycling plate 27 is provided with a traction groove 28. The inner surface of the side plate 2 14 is fixedly connected with a top rod 30. The top rod 30 passes through the left and right ends of the recycling plate 27 through the traction groove 28. The outer surface of the left end of the top rod 30 is fixedly connected with a top sleeve 21. The outer surface of the top rod 30 is threadedly connected with a top sleeve 1 29. The top sleeve 2 31 and the top sleeve 1 29 are located on the left and right sides of the recycling plate 27, respectively.

[0032] The recycling plate 27 is arc-shaped and made of elastic material. The outer surface of the top rod 30 slides in contact with the inner wall of the traction groove 28. The top sleeve 1 29 and the top sleeve 2 31 are both made of wear-resistant material. The conveyor 1 11 and the conveyor 2 13 are vertically distributed.

[0033] By adopting the above technical solution, when the conveyor 2 13 continuously conveys the lunch box 15, a recycling component is set up to prevent the baffle 18 and positioning plate 17 from obstructing the subsequent lunch box 15. When the recycling component is working, the conveyor 1 11 stops working, and at the same time, the telescopic rod 21 drives the positioning plate 17 to move towards the support plate 20. The side plate 2 14 is used to fix and support the top rod 30. The fixing plate 2 26 applies a certain elastic force to the fixing plate 1 25 through the recycling plate 27, so that the included angle between the baffle 18 and the positioning plate 17 is kept within an appropriate range. When the baffle 18 and the positioning plate 17 move towards the support plate 20, the baffle 18 and the positioning plate 17 will pass through the fixing plate 1 25 and the fixing plate 2 26. The recycling plate 27 moves synchronously. The top sleeve 29 is distributed on both sides of the recycling plate 27. During the movement of the recycling plate 27, the top sleeve 29 will block and limit the recycling plate 27. Under the blocking effect of the top sleeve 29, the recycling plate 27 will undergo elastic deformation, thereby gradually reducing the bending range of the recycling plate 27. At this time, the recycling plate 27 drives the baffle 18 to rotate around the pivot 23 through the fixing plate 25, so that the angle between the baffle 18 and the positioning plate 17 gradually increases. This can drive the baffle 18 to gradually flip in a direction parallel to the support plate 20, thereby effectively reducing the risk of the baffle 18 blocking the lunch box 15 and helping to make the movement of the lunch box 15 more stable.

[0034] Working principle: When the conveying device is working, the plastic lunch box 15 moves to the upper side of the support plate 35 under the drive of the conveyor 11. The side plate 12 supports the hinge seat 33 through the support rod. The electric push rod 34 supports the guide block 44 through the universal joint 43. The position of the support plate 35 can be kept stable under the lifting action of the guide block 44. The stacking height of the lunch boxes 15 will gradually increase. The electric push rod 34 can push the support plate 35 through the guide block 44 and the guide groove 41, so that the distance between the support plate 35 and the support rod gradually increases, allowing the lunch box 15 to slide accurately to the corresponding position. A part of the outer surface of the lunch box 15 will contact the left side of the positioning plate 17. The positioning plate 17 can buffer the inertia of the lunch box 15 and play a positioning role, so that the position of the lunch box 15 remains stable. When the lunch box 15 moves to the upper side of the support plate 35 and the displacement plate 39, the lunch box 15... The lower surface of the 5th ball will contact the outer surfaces of the first ball 38 and the second ball 47. The rotation of the first ball 38 and the second ball 47 can reduce the friction during the movement of the lunch box 15 to a certain extent, thus making the movement of the lunch box 15 more stable. At the moment the second conveyor 13 starts, the baffle 18 can position the lunch box 15, thereby reducing the risk of the lunch box 15 tipping backward due to inertia. The second fixed plate 26 applies a certain elastic force to the first fixed plate 25 through the recovery plate 27, so that the angle between the baffle 18 and the positioning plate 17 is kept within an appropriate range. The recovery plate 27 drives the baffle 18 to rotate around the pivot 23 through the first fixed plate 25, so that the angle between the baffle 18 and the positioning plate 17 gradually increases, thereby driving the baffle 18 to gradually flip in a direction parallel to the support plate 20, thus effectively reducing the risk of the baffle 18 blocking the lunch box 15.
