Description

Technical Field

[0001] This invention relates to the field of shell sorting technology, and more specifically, to a reversing and sorting device for thin-walled shells of a freezer. Background Technology

[0002] In the manufacturing process of refrigeration equipment, thin-walled shells are key components. Their processing and assembly have strict requirements on the sorting and orientation of the shells. Automatic sorting of thin-walled shells mainly refers to sorting the scattered and disordered shells through a device to obtain a series of shells with the same opening direction, which facilitates the use of subsequent work stations.

[0003] Traditional thin-walled shell sorting devices for refrigeration units often rely on complex power systems to move and sort the shells. Common methods include motor-driven conveyor belts or hydraulic drives, which move the shells along tracks to complete the sorting. However, the continuous operation of these devices consumes a large amount of electricity or hydraulic oil, resulting in high energy costs. The overall cost of purchasing, installing, and maintaining the equipment is also significantly increased due to the complexity of the power system. In terms of sorting efficiency, when relying solely on conveyor belts, if there are many shells, uneven speeds often lead to collisions and stacking. This can not only cause scratches and structural damage to the shells but also seriously affect subsequent conveying, processing, and assembly processes, greatly hindering the improvement of production efficiency. At the same time, most existing sorting devices are single-function, only able to sort the shells and unable to effectively adjust their posture. To meet the specific requirements of subsequent production processes for shell posture, companies have to add a dedicated posture adjustment process and purchase corresponding supporting equipment, which undoubtedly further increases production costs, extends the production cycle, and reduces product production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a reversing and sorting device for thin-walled shells of a freezer, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a refrigerant thin-walled shell flipping and sorting device is provided, including a conveying assembly, a first support frame, and a second support frame. The first support frame is disposed above the conveying assembly, and the second support frame is disposed on one side of the first support frame. A cylindrical tube is fixedly connected to the upper side of the first support frame, and a feeding cylinder is fixedly connected to one side of the cylindrical tube. A support plate is fixedly connected to the upper side of the second support frame, and an arc-shaped placement plate is fixedly connected to the upper side of the support plate. The arc-shaped placement plate is used to place the shell, and a control device and a feeding device are provided on one side of the arc-shaped placement plate. A flipping device is provided inside the cylindrical tube. The shell is placed arbitrarily on the arc-shaped placement plate. The shell moves downwards with the inclination of the arc-shaped placement plate. Under its own gravity, the shell pushes the control device to rotate. The rotation of the control device does not obstruct the shell, allowing it to continue moving downwards into the cylindrical tube. The rotation of the control device drives the feeding device to rotate. The rotation of the feeding device controls the downward speed of the shell, causing the shells to be intermittently sorted. When the shell moves into the cylindrical tube, it pushes the flipping device to rotate. The rotation of the flipping device causes the shell to flip, so that the open end of the shell always faces upwards and the closed end faces downwards.

[0006] As a further improvement to this technical solution, the control device includes a first side plate fixedly connected to one side of the support plate, a fixed rod rotatably connected to the upper side of the first side plate, a swing rod fixedly connected to the upper end of the fixed rod, and the end of the swing rod away from the fixed rod passing through the side wall of the arc-shaped placement plate.

[0007] As a further improvement to this technical solution, the feeding device includes a second side plate fixedly connected to one side of the support plate, a rotating rod fixedly connected to the upper side of the second side plate, a cylindrical block fixedly connected to the upper end of the rotating rod, and multiple control rods arranged in a circular array on the outer circumference of the cylindrical block.

[0008] As a further improvement to this technical solution, the flipping device includes a connecting rod fixedly connected to the inner wall of the cylindrical tube, a movable rod rotatably connected to the connecting rod, and a spring damper fixedly connected to one side of the connecting rod and one side of the movable rod.

[0009] As a further improvement to this technical solution, two notches are provided on one side of the arc-shaped placement plate, and the control rod and swing rod are respectively located at the two notches.

[0010] As a further improvement to this technical solution, a limiting plate is rotatably connected to the upper side of the second side plate, and a snap-fit ​​block is fixedly connected to the other end of the limiting plate. A fixing plate is fixedly connected to the lower end of the rotating rod, and the fixing plate is located below the rotating rod. Multiple snap-fit ​​grooves that are adapted to the snap-fit ​​block are opened on the outside of the fixing plate.

[0011] As a further improvement to this technical solution, a cylindrical rod is fixedly connected to the lower end of the swing arm, and a pull rope is fixedly connected to the lower end of the cylindrical rod. The other end of the pull rope is fixedly connected to the limiting plate and the side away from the locking block.

[0012] As a further improvement to this technical solution, a rectangular block is provided between the cylindrical block and the fixed plate, and the rectangular block is sleeved on the rotating rod. One side of the rectangular block is fixedly connected to the support plate, and a tension spring is fixedly connected to the upper side of the limiting plate on one side of the rectangular block.

[0013] As a further improvement to this technical solution, the lower end of the movable rod is provided with a barb, and the barb is located at the center of the feed cylinder. When the closed end of the housing contacts the barb, the closed end of the housing pushes the barb to rotate. When the open end of the housing contacts the barb, the barb extends into the open end of the housing and pushes the barb to rotate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this thin-walled shell flipping and sorting device for a freezer, the shells are placed arbitrarily on an arc-shaped placement plate. Driven by the weight of the shells themselves, a series of smooth and continuous movements are achieved. The weight of the shells drives the swing arm to rotate, smoothly entering the feeding cylinder. No additional power equipment is required throughout the process, which greatly saves energy consumption. At the same time, the rotation of the swing arm triggers the linkage of a series of components such as the cylindrical rod, the pull rope, and the limit plate, so that the control rod can sequentially control the movement of shells at different positions, ensuring that each shell maintains a proper interval and orderly arrangement. This provides a good material preparation foundation for subsequent production processes such as conveying, processing, and assembly, and greatly improves the smoothness and reliability of the overall production process.

[0015] 2. In this thin-walled shell flipping and sorting device for the refrigeration unit, when the shell enters the cylindrical tube, regardless of whether the shell initially enters with its closed end facing down or its open end facing down, the shell's posture can be precisely adjusted to always have its closed end facing down and its open end facing up through the coordinated action of structures such as barbs, movable rods, and spring dampers and gravity. This reduces the additional adjustments and positioning operations caused by the shell's chaotic orientation during the production process, helps continuous production lines receive shells in the same posture, and significantly improves the overall production rhythm and efficiency.

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.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] Please see Figures 1-10As shown, the purpose of this embodiment is to provide a refrigerant thin-walled shell flipping and sorting device, including a conveying assembly 1, a first support frame 11, and a second support frame 12. The first support frame 11 is disposed above the conveying assembly 1, and the second support frame 12 is disposed on one side of the first support frame 11. A cylindrical tube 1101 is fixedly connected to the upper side of the first support frame 11, and a feed cylinder 1102 is fixedly connected to one side of the cylindrical tube 1101. A support plate 1201 is fixedly connected to the upper side of the second support frame 12. An arc-shaped placement plate 1202 is fixedly connected to the upper side of the support plate 1201. The arc-shaped placement plate 1202 is used to place the shell. The shell is hollow inside. One end of the shell is an open end and the other end is a closed end. The arc-shaped placement plate 1202 and the feed cylinder 1102 are both inclined. The arc-shaped placement plate 1202 and the feed cylinder 1102 are connected. A control device 2 and a feeding device 3 are provided on one side of the arc-shaped placement plate 1202. A flipping device 4 is provided inside the cylindrical cylinder 1101. The shell is placed arbitrarily on the arc-shaped placement plate 1202. The shell moves downward with the inclination of the arc-shaped placement plate 1202. Under its own gravity, the shell pushes and contacts the control device 2, which in turn drives the control device 2 to rotate. The rotation of the control device 2 does not obstruct the shell, allowing it to continue moving downward into the cylindrical tube 1101. No additional power equipment is required throughout the process, greatly saving energy consumption. The rotation of the control device 2 drives the feeding device 3 to rotate. The rotation of the feeding device 3 controls the downward speed of the shell, allowing the shells to be sorted intermittently. This ensures that each shell maintains a suitable interval and orderly arrangement, providing a good material preparation foundation for subsequent production processes such as conveying, processing, and assembly, and greatly improving the smoothness and reliability of the overall production process. When the shell moves into the cylindrical tube 1101, the shell pushes the flipping device 4 to rotate. The rotation of the flipping device 4 causes the shell to flip, so that the open end of the shell is always facing upward. The shell with the open end facing upward falls from the cylindrical tube 1101 onto the conveying assembly 1 and is conveyed away.

[0021] Please see Figures 3-6 As shown, the control device 2 includes a first side plate 21 fixedly connected to one side of the support plate 1201. A fixed rod 22 is rotatably connected to the upper side of the first side plate 21. A swing rod 23 is fixedly connected to the upper end of the fixed rod 22. The end of the swing rod 23 away from the fixed rod 22 passes through the side wall of the arc-shaped placement plate 1202. Please refer to [link / reference]. Figures 1-2 As shown, two notches 1203 are provided on one side of the arc-shaped placement plate 1202, and the control rod 35 and the swing rod 23 are respectively set at the positions of the two notches 1203; First, multiple housings are arbitrarily placed on the arc-shaped placement plate 1202, with the housings positioned sequentially on one side of the control rod 35, between two control rods 35, and between the control rod 35 and the swing rod 23. The control rod 35 blocks the housings on the arc-shaped placement plate 1202. The housings located between the control rod 35 and the swing rod 23 move downwards with the inclined surface of the arc-shaped placement plate 1202. In the initial state, the swing rod 23 acts as a blocker for the housings. When the housings move downwards, they come into contact with the swing rod 23, and the swing rod 23 rotates downwards under its own weight. The rotating swing rod 23 no longer blocks the housings, allowing the housings to continue moving downwards into the feed cylinder 1102 and into the cylindrical cylinder 1101. The rotation of the swing rod 23 is driven by the weight of the housings themselves, eliminating the need for an additional power device to move the housings, saving energy and equipment costs, making the feeding process more natural and smooth, and improving work efficiency.

[0022] Please see Figure 6 As shown, a cylindrical rod 24 is fixedly connected to the lower end of the swing rod 23, and a pull rope 25 is fixedly connected to the lower end of the cylindrical rod 24. The other end of the pull rope 25 is fixedly connected to the limiting plate 32 on the side away from the locking block 33. When the swing rod 23 rotates downward, it drives the cylindrical rod 24 to rotate. The rotation of the cylindrical rod 24 pulls the pull rope 25 to rotate.

[0023] Please see Figures 3-7 As shown, the feeding device 3 includes a second side plate 31 fixedly connected to one side of the support plate 1201. A rotating rod 34 is fixedly connected to the upper side of the second side plate 31. A cylindrical block is fixedly connected to the upper end of the rotating rod 34. Multiple control rods 35 are arranged in a circular array around the outer side of the cylindrical block. A limiting plate 32 is rotatably connected to the upper side of the second side plate 31. A snap-fit ​​block 33 is fixedly connected to the other end of the limiting plate 32. A fixing plate 36 is fixedly connected to the lower end of the rotating rod 34. The fixing plate 36 is located below the rotating rod 34. Multiple snap-fit ​​grooves 37 that are adapted to the snap-fit ​​blocks 33 are opened on the outer side of the fixing plate 36. A rectangular block 38 is provided between the cylindrical block and the fixing plate 36. The rectangular block 38 is sleeved on the rotating rod 34. One side of the rectangular block 38 is fixedly connected to the support plate 1201. A tension spring 39 is fixedly connected to the upper side of the limiting plate 32 on one side of the rectangular block 38. Pull rope 25 drives limit plate 32 to rotate and stretches tension spring 39. The rotation of limit plate 32 drives locking block 33 to rotate. Locking block 33 rotates and does not contact locking groove 37, disengaging from locking groove 37. This means locking block 33 does not limit the position of fixed plate 36. At this time, the housing between the two control rods 35 pushes control rod 35 to rotate under its own weight. The rotation of control rod 35 causes the housing between the two control rods 35 to move downward toward swing rod 23, while the housing on one side of control rod 35 moves between the two control rods 35. When control rod 35 rotates, it drives fixed plate 36 to rotate through rotating rod 34. When the lower swing rod 23 disengages from the housing... The reaction force of the tension spring 39 drives the limiting plate 32 to rotate and reset. The rotation of the limiting plate 32 drives the swing rod 23 to reset via the pull rope 25. The reset of the swing rod 23 prepares for the next shell to be unloaded. At the same time as resetting, the limiting plate 32 moves into the snap-fit ​​groove 37, so that the snap-fit ​​block 33 snaps into the snap-fit ​​groove 37 and limits the fixed plate 36. The downward speed of the shell is controlled by the control rod 35, so that the shells can be intermittently sorted. This can ensure that each shell maintains a certain interval and order, avoid mutual collision, accumulation or chaos between shells, facilitate the automation control of the entire production process, reduce manual intervention, and improve production efficiency and consistency.

[0024] Please see Figures 8-10 As shown, the flipping device 4 includes a connecting rod 41 fixedly connected to the inner wall of the cylindrical tube 1101, a movable rod 42 rotatably connected to the connecting rod 41, a spring damper 43 fixedly connected to the side wall of the connecting rod 41 and one side of the movable rod 42, a barb 44 provided at the lower end of the movable rod 42, and the barb 44 is located at the center of the feed tube 1102. When the closed end of the shell contacts the barb 44, the closed end of the shell pushes the barb 44 to rotate. When the open end of the shell contacts the barb 44, the barb 44 extends into the open end of the shell and pushes the barb 44 to rotate. When the shell moves into the cylindrical tube 1101 through the feed cylinder 1102, since the shell is placed arbitrarily, there are two situations during the unloading process. The first situation is that the closed end of the shell faces downwards. Because the closed end of the shell is a solid end, when the shell continues to fall under gravity, the closed end will directly exert a downward thrust on the barb 44, causing the barb 44 to rotate around its pivot point. The barb 44 is connected to the movable rod 42, and the rotation of the barb 44 will drive the movable rod 42 to rotate. Simultaneously, the movable rod 42 is connected to the spring damper 43. During the rotation of the movable rod 42, the spring damper 43 is stretched. When the spring damper 43 is stretched, it stores elastic potential energy on one hand, and on the other hand... Its damping characteristics will buffer and hinder the rotation of the movable rod 42, so that the entire rotation process will not be too violent. Since the shell is placed at an angle inside the feed cylinder 1102, the center of gravity of the shell is not on the vertical center line. When the closed end pushes the hook 44 to rotate, as the shell continues to fall, gravity will generate a torque that causes it to rotate on the inclined shell. At the same time, the closed end and the hook 44 have interacted. The position of the hook 44 and the movable rod 42 has a certain constraint on the movement of the shell. Under the combined action of gravity, rotational inertia and constraint conditions, the shell will gradually adjust its posture during the fall, so that the closed end of the shell always faces downward and the open end faces upward. In the second scenario, the shell opening is facing downwards. When the shell enters the cylindrical tube 1101 with the opening facing downwards, the barb 44 will extend into the interior of the shell from the opening. Since the interior of the opening is empty, the barb 44 can directly enter the interior of the shell. As the shell continues to fall, the movable rod 42 contacts the edge of the shell opening. The shell continues to fall under the action of gravity, and the edge of the shell opening will exert an upward thrust on the movable rod 42, causing the movable rod 42 to rotate upwards around its connection point. Similarly, the rotation of the movable rod 42 will stretch the spring damper 43, causing it to store elastic potential energy and generate a damping effect. Furthermore, since the closed end of the shell is a solid structure, its mass is relatively larger than that of the open end, meaning its center of gravity is closer to the closed end. During the fall, under the influence of gravity, the larger closed end is more likely to tend downwards. At the same time, the interaction between the spring damper 43 and the movable rod 42 will give the shell an adjustment torque, causing the shell to flip. This ensures that the closed end of the shell always faces downwards and the open end faces upwards during the fall, ensuring that each shell maintains a consistent orientation during the fall. This improves the accuracy of the entire sorting process and is beneficial for subsequent processing steps.

[0025] In practical use, the thin-walled shell flipping and sorting device for the freezer of the present invention first places the shell arbitrarily on the arc-shaped placement plate 1202. The control rod 35 blocks the shell. The shell located between the control rod 35 and the swing rod 23 moves downward with the inclined surface of the arc-shaped placement plate 1202. The shell pushes the swing rod 23 downward by its own gravity and enters the feed cylinder 1102. This process requires no additional power and is natural and smooth. The rotation of the swing rod 23 drives the cylindrical rod 24, which in turn pulls the pull rope 25, causing the limiting plate 32 to rotate and stretch the tension spring 39. The locking block 33 disengages from the locking groove 3. 7. The housing located between the two control rods 35 pushes the control rod 35 to rotate and move downward. The housing located on one side of the control rod 35 moves between the two control rods 35. The rotation of the control rod 35 drives the fixed plate 36 to rotate. After the swing rod 23 disengages from the housing, the tension spring 39 drives the limit plate 32 to reset, thereby resetting the swing rod 23. At the same time, the locking block 33 re-locks the locking groove 37 to limit the fixed plate 36, ensuring that each housing maintains a certain interval and order, avoiding mutual collision, accumulation or chaos between housings, which is conducive to the smooth progress of subsequent production processes. There are two scenarios when the shell enters the cylindrical tube 1101. If the closed end of the shell faces downwards, it pushes the hook 44 to rotate, causing the movable rod 42 to pull the spring damper 43. Because the shell is tilted within the feed cylinder 1102, gravity generates a torque that causes it to rotate. Combined with the constraints of the hook 44 and the movable rod 42 on its movement, the closed end of the shell always faces downwards and the open end upwards when it falls. If the open end of the shell faces downwards, the hook 44 enters from the open end, and the movable rod 42 is pushed upwards by the edge of the opening, pulling the spring damper 43. Because the closed end has a large mass and its center of gravity is close to it, the torque generated by gravity and the interaction of the spring damper 43 and the movable rod 42 causes the shell to flip. Ultimately, the closed end always faces downwards and the open end upwards when it falls, ensuring that each shell maintains a consistent orientation during its descent. This makes the production process smoother, reduces the need for adjustments and positioning due to misalignment of the shells, and allows each shell to enter subsequent equipment in the same posture on a continuous production line, helping to improve the overall production rhythm and thus increase production efficiency.
