Description

Technical Field

[0001] This invention relates to the field of casting processing equipment technology, specifically to an automated inner wall processing device for container casting. Background Technology

[0002] Shot blasting is the core process for surface treatment of the inner wall of metal containers. It is widely used in the removal of rust, oxide scale, welding slag and impurities from the inner walls of pressure vessels, chemical storage tanks, pipeline containers, and irregularly shaped metal silos. The inner wall of the container after shot blasting can significantly improve the surface roughness and enhance the adhesion of subsequent coatings and anti-corrosion layers. It is a key process to ensure the service life and safety of the container. Current traditional shot blasting equipment and processes for cleaning the inner walls of containers have many technical defects, such as: poor equipment adaptability and insufficient versatility. The clamping mechanism, shot blasting nozzle, and protective structure of traditional shot blasting devices are mostly designed with fixed specifications, which can only be adapted to containers of a single diameter or width. The degree of automation is low and the dependence on manual labor is high. Container loading, positioning, and unloading rely heavily on manual assistance. After shot blasting, the residual sand and shot in the container need to be manually dumped and recycled, which is labor-intensive and has low operating efficiency.

[0014] The present invention provides an automated inner wall treatment device for container casting, which has the following advantages: 1. The conveying structure drives the opening and closing of the first clamping arm via the first electric slide rail, enabling centered and limited conveying of containers of different diameters; the protective unit can be replaced with buckles of different diameters, and the end of the guide pipe can be replaced with nozzles of different lengths; the second clamping arm and crossbar of the recovery structure can adjust their width according to the container size, allowing it to adapt to various diameters and lengths of container workpieces without the need for additional custom-made special tooling, effectively reducing the changeover cost for multi-specification production and expanding the applicable scenarios of the equipment.

[0015] 2. The equipment can autonomously complete the entire process of orderly container release, station positioning, shot blasting cleaning of the inner wall, and residual shot recovery: The baffle mechanism at the conveying end can release individual containers in accordance with the processing rhythm, eliminating the need for manual arrangement and positioning; the recovery end automatically pours out the residual shot in the container through the flipping unit, replacing manual pouring operations, reducing manual intervention in the operation process, and reducing the labor intensity of operators to a certain extent.

[0016] 3. The processing structure adopts an operation mode that links axial lifting and circumferential rotation.

This can effectively prevent shot from flying out during shot blasting operations and reduce the risk of shot accidentally injuring operators. At the same time, it can reduce shot splash loss and help maintain the cleanliness of the work site.

[0018] In summary, this invention arranges three functional units—conveying, processing, and recycling—along the container conveying direction.

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-8 As shown, the present invention provides a technical solution: an automated inner wall processing device for container casting, comprising a base 1, a conveying structure 2, a recovery structure 3, a processing structure 4, and a protective unit 5; the conveying structure 2 is fixedly disposed on the upper left wall of the base 1, the recovery structure 3 is fixedly disposed on the right side of the conveying structure 2, the processing structure 4 is disposed on the front side of the base 1, and the processing structure 4 corresponds to the conveying structure 2; the protective unit 5 is detachably mounted on the processing structure 4; wherein the conveying structure 2 is used for the linear conveying of containers of different diameters or widths, and can cooperate with processing to release a single container; the recovery structure 3 is used for the recovery of sand or shot after the inner wall of the container is processed; the processing structure 4 is used for the rotation processing of the inner wall of the container; and the protective unit 5 is used to cooperate with the processing structure 4 to fit containers of different diameters and prevent shot from flying out during shot blasting.

[0023] As a further embodiment of the present invention, the conveying structure 2 includes a conveyor belt assembly 21, a first electric slide rail 22, a pair of first clamping arms 23, a pair of baffles 24, a stop arm 25, and an electric push rod 26; the conveyor belt assembly 21 is fixedly disposed in the middle of the upper left wall of the base 1, the first electric slide rail 22 is fixedly disposed in the upper wall of the base 1 and located below the conveyor belt assembly 21, the first electric slide rail 22 is located on the left side of the middle of the conveyor belt assembly 21, and the first electric slide rail 22 is symmetrically provided with relatively movable first sliding blocks, a pair of first... All clamping arms 23 are L-shaped. One end of each pair of first clamping arms 23 is symmetrically mounted on the first slide block of the first electric slide rail 22, and the first clamping arms 23 are movable relative to each other. The other end of each pair of first clamping arms 23 can be positioned above the conveyor belt assembly 21. A pair of baffles 24 are symmetrically mounted on the other end of each first clamping arm 23. The stop arm 25 is a V-shaped rod, and its middle part is movably mounted on the other end of one of the first clamping arms 23 via a pin. One end of the stop arm 25 passes through the top of one of the baffles 24. An electric push rod is also present. One end of the electric push rod 26 is movably mounted on the upper wall of one of the first clamping arms 23, and the telescopic end of the electric push rod 26 is movably connected to the other end of the stop arm 25. The electric push rod 26 is inclined. The container is conveyed horizontally in a straight line through the conveyor belt assembly 21. The first electric slide rail 22 drives the symmetrical first slide blocks on it to move relative to each other, which drives a pair of L-shaped first clamping arms 23 to move synchronously towards or away from each other, so that a pair of baffles 24 fixed at the ends of the first clamping arms 23 fit against the outer wall of the container. Through symmetrical clamping, cylindrical containers of different diameters are automatically centered on the conveyor belt. The telescopic movement of the electric push rod 26 drives the V-shaped stop arm 25, which is hinged to the first clamping arm 23 in the middle by a pin, to rotate around the pin. The end of the stop arm 25 that passes through the baffle 24 rotates accordingly, which can block or release the block, so as to release a single container to the processing station. When falling, it blocks the subsequent containers, and the single container is released in an orderly manner in coordination with the processing rhythm. The first electric slide rail 22 can flexibly adjust the spacing of the first clamping arms 23 according to the container diameter to adapt to the limited conveying of containers of different specifications.

[0024] More specifically, such as Figure 2 and Figure 6 As shown, the conveying structure 2 realizes the horizontal linear conveying of containers through the conveyor belt assembly 21. With the help of the first electric slide rail 22, a pair of L-shaped first clamping arms 23 are driven to open and close synchronously, causing the baffle 24 to fit against the outer wall of the container. It can adapt to cylindrical containers of different diameters and complete automatic centering and limiting. At the same time, the electric push rod 26 drives the V-shaped stop arm 25 to rotate around the pin shaft. It can accurately release a single container to the processing station in accordance with the processing rhythm and simultaneously block subsequent workpieces. While ensuring the stability of the conveying and limiting, it realizes the orderly and spaced feeding of containers of various specifications, providing a stable station positioning basis for the subsequent inner wall shot blasting process.

[0025] As a further embodiment of the present invention, the recycling structure 3 includes a second electric slide rail 31, a pair of second clamping arms 32, a pair of limiting arms 33, a crossbar 34, a recycling box 35, and a pair of flipping units 36. The second electric slide rail 31 is fixedly mounted on the upper wall of the base 1 and located on the right side of the conveyor belt assembly 21. Relatively movable second sliding blocks are symmetrically arranged on the second electric slide rail 31. Both of the second clamping arms 32 are L-shaped, with one end of each pair symmetrically mounted on the second sliding block of the second electric slide rail 31. One end of each pair of limiting arms 33 is symmetrically mounted on the second clamping arms 32, and the limiting arms 33 are located above the baffle 24. The other end of each pair of limiting arms 33 has a telescopic opening. Both ends of the crossbar 34 movably pass through the telescopic openings of the limiting arms 33, and one end of the crossbar 34 can be fixed to one of the limiting arms 33 by bolts. The other end of the crossbar 34 can extend and retract within the other limiting arm 33. The recycling box 35 is placed on the upper right wall of the base 1, and both the front and rear side walls of the recycling box 35 are provided with... Equipped with handrails, a pair of flipping units 36 are symmetrically arranged on the other end of the second clamping arm 32. After the shot-blasting container is transported to the recycling station, it is blocked and limited by the crossbar 34. Then, the second electric slide rail 31 drives the second slide block symmetrically arranged on it to move relative to each other, driving the pair of L-shaped second clamping arms 32 to move synchronously towards or away from each other to adapt to the diameter of the container to be recycled, so as to achieve stable clamping of the container. A pair of limiting arms 33 move synchronously with the second clamping arm 32. The two ends of the crossbar 34 adaptively extend and retract within the extension port of the limiting arm 33. After adjusting to match the width of the container, a lateral limit is formed on the upper part of the container to prevent the container from falling to the right end of the conveyor belt assembly 21. The pair of flipping units 36 move synchronously, driving the clamped and limited container to flip as a whole. The shot material remaining in the container falls into the recycling box 35 under the action of gravity, completing the unified collection of shot material. Handrails are provided on the front and rear side walls of the recycling box 35 to facilitate the operator to move, replace and transfer shot material.

[0026] More specifically, such as Figure 2 and Figure 7 As shown, the recycling structure 3 drives a pair of second clamping arms 32 to open and close synchronously via the second electric slide rail 31, which can adapt to containers of different diameters and achieve stable clamping. With the help of the crossbar 34, which can adaptively extend and retract with the distance between the clamping arms, a lateral limit is formed on the upper part of the container to prevent the container from falling when it is transported to the end of the conveyor belt. With the help of the symmetrically arranged flipping unit 36, the clamped container can be flipped as a whole, so that the residual pellets inside the container fall into the recycling box 35 under the action of gravity and are collected, replacing the manual dumping of pellets. At the same time, the recycling box 35 with a handrail makes it convenient for operators to transfer pellets and perform daily maintenance, effectively improving the automation level and operation convenience of pellet recycling.

[0027] As a further embodiment of the present invention, the flipping unit 36 ​​includes an axle 361, a gear 362, a flipping arm 363, a hydraulic cylinder body 364, and a rack 365. The axle 361 movably passes through the other end of the second clamping arm 32. The gear 362 is fixedly mounted on one end of the axle 361. The other end of the flipping arm 363 is fixedly mounted on the other end of the axle 361, and the flipping arm 363 is parallel to the baffle 24. The flipping arm 363 is located above the crossbar 34. One end of the hydraulic cylinder body 364 is fixedly mounted on the second clamping arm 32 and located below the gear 362. One end of the rack 365 is fixedly connected to the telescopic end of the hydraulic cylinder body 364, and the other end of the rack 365 movably passes through the side wall of the other end of the second clamping arm 32. The rack 365 is provided with a plurality of teeth. 365 meshes with gear 362; the hydraulic cylinder body 364 is activated and performs a telescopic action, the telescopic end of which drives the rack 365 to reciprocate in a straight line; the teeth on the rack 365 mesh with the gear 362 fixedly mounted on the axle 361, converting the linear motion of the rack 365 into the rotational motion of the gear 362; the rotation of the gear 362 drives the axle 361 to rotate synchronously, thereby driving the tilting arm 363 fixedly mounted on the end of the axle 361 to rotate and tilt around the axis of the axle 361; the tilting arm 363 drives the container to tilt synchronously above the crossbar 34, causing the shot inside the container to pour out under the action of gravity. By controlling the telescopic stroke of the hydraulic cylinder body 364, the tilting angle of the tilting arm 363 can be precisely adjusted to meet the unloading requirements.

[0028] More specifically, such as Figure 2 and Figure 7 As shown, the tilting unit 36 ​​uses a hydraulic cylinder body 364 to drive the rack 365 to perform linear reciprocating motion. The linear motion is converted into rotational motion through the meshing transmission of the rack 365 and the gear 362. The rotational motion is then driven by the wheel axle 361 to rotate the tilting arm 363 around the axis smoothly. The overall transmission structure has stable torque and reliable operation. The tilting angle of the tilting arm 363 can be precisely adjusted by controlling the extension and retraction stroke of the hydraulic cylinder body 364. This can stably drive the clamped container to complete the tilting action, ensuring that the residual pellets inside the container are fully unloaded, and providing stable tilting power support for the automatic pellet recycling process.

[0029] As a further embodiment of the present invention, the processing structure 4 includes a mounting base 41, a pair of first limiting rods 42, a spiral rod 43, a drive assembly 44, and a shot blasting machine body 45.

The drive assembly 44 is movably fitted onto the spiral rod 43 and the first limiting rods 42. The shot blasting machine body 45 is located on the right side of the mounting base 41 and is connected to the drive assembly 44 through a pipe. The convex mounting base 41 serves as an integral support for the base 1 to improve stability and is fixedly arranged on the base. 1. The front side, located between the first electric slide rail 22 and the second electric slide rail 31, provides a stable mounting base for each component; a pair of first limiting rods 42 are symmetrically fixed on the mounting base 41 to form a vertical guide structure; a spiral rod 43 is fixedly installed between the two first limiting rods 42 as a lifting transmission rod of the drive assembly 44; the drive assembly 44 is movably mounted on the first limiting rods 42 and the spiral rod 43, and can make vertical linear movements along the first limiting rods 42, with the spiral rod 43 providing transmission support to achieve stable lifting; the shot blasting machine body 45 is placed on the right side of the mounting base 41 and is connected to the drive assembly 44 through a pipe, continuously feeding the shot used for shot blasting to the drive assembly 44, and cooperating with the lifting and rotating actions of the drive assembly 44 to carry out all-round shot blasting cleaning operations on the inner wall of the container.

[0030] More specifically, such as Figure 3 , Figure 5 As shown, the processing structure 4 uses a convex mounting base 41 as the overall support foundation, which is set on the side of the conveying station to provide a stable mounting carrier for each functional component; the first limiting rod 42 arranged symmetrically forms a vertical guide structure, which, together with the central spiral rod 43, realizes the smooth lifting and lowering transmission of the drive component 44. With the shot blasting machine body 45 on the side continuously supplying shot, it can drive the working end to move smoothly along the container axis, providing stable lifting power and material conveying guarantee for all-round shot blasting cleaning of the inner wall of the container.

[0031] As a further embodiment of the present invention, the drive assembly 44 includes a drive frame 441, a pair of bearings 442, a spiral sleeve 443, a guide tube 444, a rotating interface 445, a frame 446, a motor 447, three pulleys 448, and a transmission belt 449. The drive frame 441 has an I-shaped structure, and both ends of the drive frame 441 are symmetrically provided with a first lifting hole 6 and a second lifting hole 7. One end of the drive frame 441 is movably fitted onto the first limiting rod 42 through the first lifting hole 6, and the drive frame 441 is movably fitted onto the spiral rod 43. A pair of bearings 442 are respectively embedded in the middle of both ends of the drive frame 441. The spiral sleeve 446... A screw rod 443 is fixedly connected to the middle of a bearing 442 at one end of a drive frame 441, and a spiral sleeve 443 is screwed onto the screw rod 43. One end of a guide tube 444 is fixedly connected to the middle of another bearing 442. One end of a rotating interface 445 is fixedly connected to one end of the guide tube 444, and the two ends of the rotating interface 445 can rotate relative to each other. One end of a frame 446 is fixedly located in the middle of the drive frame 441, and the other end of the frame 446 is located on the right side of the drive frame 441. A motor 447 is fixedly located on the lower wall of the other end of the frame 446, and the drive end of the motor 447 moves through the frame 446. Three pulleys 448 are respectively fixedly mounted on the drive of the motor 447. Three pulleys 448 are arranged in a triangle on one end of the spiral sleeve 443 and one end of the guide tube 444. A transmission belt 449 is movably mounted on each of the three pulleys 448. When the motor 447 is energized and started, its drive end drives the fixedly mounted pulley 448 to rotate. This pulley 448, through the transmission belt 449, drives the other two pulleys 448 arranged in the triangle to rotate synchronously. The three pulleys 448 respectively drive the drive end of the motor 447, the top end of the spiral sleeve 443, and one end of the guide tube 444 to rotate synchronously. The spiral sleeve 443 rotates within a bearing 442 at one end of the drive frame 441. Because the spiral sleeve 443 and... The spiral rod 43 is screw-fitted, and the drive frame 441 is fitted onto the first limiting rod 42 through the first lifting hole 6 to form a vertical guide. The rotational motion of the spiral sleeve 443 is converted into the vertical linear lifting motion of the drive frame 441 along the first limiting rod 42. At the same time, the guide pipe 444 rotates 360 degrees synchronously with the pulley 448 in the bearing 442 at the other end of the drive frame 441. The two ends of the rotating interface 445 can rotate relative to each other. During the continuous rotation of the guide pipe 444, it maintains pipe connection with the shot blasting machine body 45 and stably conveys shot, ultimately realizing the synchronous linkage between the lifting of the drive frame 441 and the rotation of the guide pipe 444.

[0032] More specifically, such as Figure 3 and Figure 5As shown, the drive assembly 44 uses a single motor 447 in conjunction with three triangularly distributed pulleys 448 and a transmission belt 449 to drive the spiral sleeve 443 and the guide tube 444 to rotate synchronously. With the spiral engagement of the spiral sleeve 443 and the spiral rod 43, combined with the vertical guidance formed by the first limit rod 42 through the first lifting hole 6, the rotational motion can be converted into the vertical linear lifting motion of the drive frame 441, while simultaneously driving the guide tube 444 to achieve 360° circumferential rotation. The rotating interface 445 can maintain stable communication with the shot blasting pipeline during the rotation of the guide tube 444. The whole assembly achieves synchronous linkage of lifting and rotation with a single power source. The structure is compact and has good transmission synchronization. It can drive the working end to move along the axial direction of the container while completing the circumferential shot blasting operation, providing a stable transmission guarantee for all-round cleaning of the inner wall.

[0033] As a further embodiment of the present invention, the protective unit 5 includes a pair of second limiting rods 51, several buckle plates 52, a pair of nuts 53, and a spring 54; one end of each pair of second limiting rods 51 movably passes through the second lifting hole 7 at the other end of the drive frame 441, and the second limiting rods 51 are symmetrically arranged; the several buckle plates 52 are all disc structures of different diameters, and each buckle plate 52 has an installation hole in the middle that fits with the guide tube 444; the buckle plate 52 is detachably fitted onto the other end of the guide tube 444, and the buckle plate 52 is movably fitted onto the other end of the second limiting rods 51; the pair of nuts 53 are screwed onto the other end of the second limiting rods 51, and the nuts 53 are located below the buckle plates 52 for fixing; the spring 54 is movably fitted onto the guide tube 444, and the spring 54 is located between the upper wall of the buckle plate 52 and the lower wall of the other end of the drive frame 441; the second limiting rods 51 movably pass through the second lifting hole 7 at the other end of the drive frame 441 to form a vertical guide limit; according to the contents to be processed For the diameter of the device, a disc-shaped buckle plate 52 of corresponding diameter is selected. The buckle plate 52 is detachably fitted onto the other end of the guide tube 444 through the central mounting hole. At the same time, the buckle plate 52 is movably fitted onto the ends of the two second limiting rods 51. Then, the nut 53 is screwed onto the other end of the second limiting rod 51 to form a positioning and fixation below the buckle plate 52, preventing the buckle plate 52 from falling off. The spring 54 is movably fitted onto the guide tube 444, with its two ends respectively abutting against the lower wall of the other end of the drive frame 441 and the upper wall of the buckle plate 52. The spring 54 continuously applies a downward elastic force to the buckle plate 52. When the drive assembly 44 drives the guide tube 444 to move vertically, the second limit rod 51 moves synchronously with the drive frame 441. Under the elastic force of the spring 54, the buckle plate 52 always fits the container opening and moves smoothly with the guide tube 444. The second limit rod 51 restricts the circumferential deflection of the buckle plate 52 and will not obstruct the guide tube 444. Buckles 52 of different diameters can be adapted to containers of different diameters to prevent shot from flying out during shot blasting.

[0034] More specifically, such as Figure 4 , Figure 5 and Figure 8As shown, the protective unit 5 is equipped with multiple detachable buckle plates 52 of different diameters to match containers and workpieces of different diameters. With the elastic force of the spring 54, the buckle plate 52 is continuously pushed downwards. Combined with the vertical guidance and circumferential anti-rotation constraint of the second limit rod 51, the buckle plate can always be in contact with the container mouth and not rotate synchronously with the guide tube during the lifting and lowering operation of the guide tube 444, effectively preventing shot from flying out during the shot blasting process. The buckle plate is fixed at the lower end by the nut 53, and the disassembly and replacement operation is simple. While improving the safety protection performance, it also has good specification adaptability and maintenance convenience.

[0035] As a further embodiment of the present invention, the other end of the guide tube 444 is detachably screwed with nozzles 8 of different lengths to fit containers of different diameters; the nozzles 8 can be driven by the motor 447 and the pulley 448 to rotate 360 ​​degrees with the guide tube 444; the drive frame 441 can drive the spiral sleeve 443 to rotate by the motor 447 and move up and down with the help of the first limit rod 42.

[0036] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0037] The equipment uses base 1 as the overall installation support foundation. Each functional structure and component is positioned and assembled based on base 1. The device operates in a coordinated manner throughout the entire process, including automatic container conveying and positioning, shot blasting cleaning of the inner wall, shot blasting protection, and automatic shot recovery. After the operation starts, the conveyor structure 2 first performs the container conveying and positioning actions: the conveyor belt assembly 21 carries the cylindrical container for horizontal linear conveying, the first electric slide rail 22 drives the first slide block on it to move in opposite directions, and drives a pair of first clamping arms 23 to open and close synchronously, so that the symmetrically installed baffles 24 fit against the outer wall of the container, and automatically center and position containers of different diameters; the electric push rod 26 performs telescopic action, driving the V-shaped baffle arm 25 with the pin hinge in the middle to rotate around the axis. When the end of the baffle arm 25 fits against the side wall of the container, it blocks and limits the movement. When it is detached from the container, it releases a single container to the processing station; After the container arrives at the processing station, the processing structure 4 and the drive assembly 44 work together to perform shot blasting: the mounting base 41 serves as the overall support carrier, and a pair of first limiting rods 42 and a spiral rod 43 form a vertical guide and transmission mechanism; the drive frame 441 is movably mounted on the first limiting rods 42 and the spiral rod 43 through the first lifting hole 6; the motor 447 is powered on and rotates, its drive end drives the pulley 448 to rotate, and synchronously drives the other two pulleys 448, which are triangularly distributed, via the transmission belt 449, thereby driving the spiral sleeve 443 and the guide tube 444 to rotate synchronously on the drive frame 441 with the help of the bearing 442; the spiral sleeve 443 rotates within the bearing 442 and spirally engages with the spiral rod 43, in The drive frame 441, under the limiting action of two first limiting rods 42, converts the rotational motion into the vertical lifting motion of the drive frame 441 along the first limiting rods 42; when the guide pipe 444 rotates, one end of the rotating interface 445 rotates with the guide pipe 444 and keeps the pipe connected, the shot blasting machine body 45 is continuously fed through the pipe, the shot is conveyed to the nozzle 8 through the guide pipe 444, the nozzle 8 rotates 360 degrees with the guide pipe 444, and in conjunction with the lifting action of the drive frame 441, the inner wall of the container is cleaned by shot blasting without dead angles; the frame 446 provides stable installation support for the motor 447, ensuring the smooth operation of the transmission structure and synchronous lifting, and its lifting is controlled by the motor 447 to drive forward or reverse rotation; During shot blasting, the protective unit 5 simultaneously performs safety protection actions: a pair of second limiting rods 51 move through the second lifting hole 7 to form a vertical guide; a buckle plate 52 of the corresponding diameter is selected according to the container opening diameter, which is detachably fitted onto the other end of the guide tube 444 and movably fitted onto the end of the second limiting rod 51; a nut 53 is screwed onto the end of the second limiting rod 51 to fix the buckle plate 52 in place; a spring 54 is fitted onto the guide tube 444, with its two ends abutting against the lower wall of the drive frame 441 and the upper wall of the buckle plate 52 respectively, continuously applying elastic pressure so that the buckle plate 52 always fits against the container opening when the nozzle 8 rises and falls, that is, the rise and fall of the guide tube 444 passes through the buckle plate 52, and the second limiting rod 51 restricts the circumferential deflection of the buckle plate 52, effectively preventing the shot from flying out, and does not hinder the rotation of the guide tube 444; After shot blasting is completed, the recovery structure 3 performs shot recovery: the second electric slide rail 31 drives the second slide block to move a pair of second clamping arms 32 toward each other, and the shot inside the container moves to the right along with the conveyor belt assembly 21, causing the container to be blocked and limited by the crossbar 34; then the relative movement of the second clamping arms 32 causes the corresponding flipping arms 363 to clamp the outer wall of the container; a pair of limiting arms 33 move synchronously with the second clamping arms 32, and the crossbar 34 adaptively extends and retracts within the extension port of the limiting arms 33; Next, the flipping unit 36 ​​is activated, and the hydraulic cylinder body 364 extends and retracts, driving the rack 365 to move linearly. The rack 365 meshes with the gear 362, driving the wheel axle 361 to rotate, which in turn drives the flipping arm 363 to flip around the axis, causing the container to flip from the left side of the second clamping arm 32 to the right side. The maximum flipping angle is 180 degrees, realizing the synchronous dumping of the internal pellets, which fall into the recycling box 35 under the action of gravity to complete the unified collection.
