Description

Technical Field

[0001] This invention relates to the field of casting processing technology, and in particular to a fully automatic casting gating and riser cleaning device. Background Technology

[0002] A riser is an additional part attached to the top or side of a casting to prevent defects. When the casting is completed, the riser and the remaining excess part need to be separated. This requires a riser separation device. The riser separation device uses an ultra-high pressure hydraulic system, with a working pressure of up to 70 MPa, to drive the piston rod of the hydraulic cylinder to move smoothly. The piston rod drives the pointed iron to move relative to the wedge iron in the groove. Based on the force-increasing characteristics of the inclined iron structure of the mating surface of the pointed iron and the wedge iron, a huge supporting force is generated, thereby separating the casting from the riser.

[0003] For example, Chinese patent CN212121634U discloses an improved casting gating and riser separation clamp, which is hydraulically driven and uses an expanding nozzle to separate the gating and riser.

[0004] However, the aforementioned separating clamps are prone to loosening due to reaction force when separating from the casting, which can lead to separation failure. Repeated separation is required, which is time-consuming and reduces work efficiency. Furthermore, the contact area remains in the same area for a long time during separation, which can cause wear on that area, resulting in the peeling and detachment of surface material, reducing service life. In addition, impurities such as casting debris or molding sand can easily adhere to and become embedded, reducing contact friction and affecting the separation effect in subsequent use. Summary of the Invention

[0005] Therefore, it is necessary to provide a fully automatic casting gating and riser cleaning device to address the problem that the contact area between the current separation clamp and the casting is in the same area for a long time, which leads to wear and reduced service life of the part.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A fully automatic casting riser and gating system cleaning device includes:

[0008] A support frame, on which a hydraulic cylinder is vertically mounted, and a push block is coaxially and fixedly connected to the telescopic end of the hydraulic cylinder. The two sides of the push block are inclined surfaces, and the lower end of the push block is a pointed tip.

[0009] Two push plates are elastically slidably disposed on the support frame along a preset direction, and the two push plates are respectively in contact with the inclined surface of the push block;

[0010] Chain plates, which are respectively wound around the outer periphery of the two push plates;

[0011] An adjustment component is located on the inclined surface of the two push plates. The adjustment component is configured to drive the chain plate to rotate around the two push plates respectively when the push block pushes the two push plates away from each other, and to maintain the chain plate at the outer periphery of the two push plates when the two push plates are close to each other.

[0012] Furthermore, the adjustment assembly includes multiple limiting plates and multiple first elastic elements. The number of limiting plates is the same as the number of first elastic elements. The multiple limiting plates are all hinged to the inclined surfaces of the two push plates and are evenly distributed along the length direction of the inclined surfaces. The hinge axes of the multiple limiting plates are parallel to each other. The multiple first elastic elements are respectively disposed between the limiting plates and the inclined surfaces of the two push plates, and the first elastic elements are located below the hinge axes of the limiting plates.

[0013] The chain plate includes multiple chain plate units, which are hinged end to end. Each chain plate unit is provided with a wedge-shaped protrusion. The upper end of the wedge-shaped protrusion is flat, and the side of the wedge-shaped protrusion that contacts the limiting plate is inclined. The upper end of the wedge-shaped protrusion can abut against the end of the limiting plate that is pushed up by the first elastic member.

[0014] Furthermore, a second elastic element is provided between the two push plates, and the second elastic element is configured to pull the two push plates to adhere to the two inclined surfaces of the push block.

[0015] Furthermore, rollers are rotatably provided at both ends of the push plate, and the rollers are in rolling contact with the inner circumference of the chain plate.

[0016] Furthermore, two sliding plates are slidably disposed on the support frame. The two sliding plates are parallel to the two push plates and are respectively connected to the two push plates. The two sliding plates are configured to drive the two push plates to move along the length direction. The push block is configured to be retractable and adaptable to the movement of the two push plates.

[0017] Furthermore, the support frame is provided with two telescopic rods, one end of which is hinged to the support frame, and the other end of which is hinged to the two sliding plates respectively.

[0018] Furthermore, the push block includes a first connecting block, a second connecting block, and a third connecting block. One end of the first connecting block is fixedly connected to the telescopic end of the hydraulic cylinder. The second connecting block is slidably connected to the other end of the first connecting block. The third connecting block is slidably connected to the second connecting block. The third connecting block has a pointed tip.

[0019] Furthermore, the first connecting block is internally provided with a multi-stage telescopic cylinder, which has a first-stage telescopic end and a second-stage telescopic end. The first-stage telescopic end and the second-stage telescopic end are coaxially arranged. The first-stage telescopic end is connected to the second connecting block, and the second-stage telescopic end is connected to the third connecting block.

[0020] Furthermore, each of the two sliding plates is equipped with a cleaning roller brush, which is in contact with the surface of the chain plate.

[0021] Furthermore, it also includes a conveyor frame for conveying castings, and a robotic arm is provided on one side of the conveyor frame, which is fixedly connected to the support frame.

[0022] The beneficial effects of this invention are:

[0023] This invention utilizes a chain plate encircling the outer periphery of two push plates. When the push block pushes the two push plates away from each other, the chain plate rotates around the outer periphery of the push plates. This rotation generates a force that moves the push plates towards the pre-set groove at the connection between the casting and the riser / gutter. This reduces the probability of the push plates detaching from the groove and minimizes instantaneous loosening caused by reaction forces. Consequently, it avoids separation failures and repeated separations, saving time and improving work efficiency. Furthermore, because the chain plate rotates when the push block pushes the two push plates away from each other, different parts of the chain plate contact the casting each time the riser / gutter is separated. This prevents wear caused by prolonged contact in the same area, reduces surface material peeling and detachment, lowers the risk of decreased fitting accuracy, significantly extends the equipment's service life, and reduces maintenance costs and downtime.

[0024] This invention, by setting a sliding plate to drive the push plate to move along the length direction, and the telescopic structure of the push block, can adapt to the removal needs of the gating risers of castings of different sizes, increasing the scope of application of the equipment and improving its versatility.

[0025] This invention provides a cleaning roller brush on the sliding plate. The cleaning roller brush contacts the surface of the chain plate and can clean the surface of the chain plate in all directions when the chain plate rotates. This effectively removes attached debris, dust, oil and other impurities, and avoids these impurities from causing additional wear due to squeezing and friction during the movement of the chain plate. This effectively reduces the contact loss between the chain plate and related components and further extends the overall service life of the equipment.

[0026] This invention uses a conveyor frame and a robotic arm. The conveyor frame enables continuous feeding of castings, while the robotic arm, combined with a vision positioning system, completes positioning, gripping, and separation operations. The entire process requires no human intervention, enabling batch processing and reducing the processing time of a single piece to one-third of the traditional manual mode. It can also operate 24 hours a day, significantly improving production efficiency. Attached Figure Description

[0046] The following reference Figures 1-9 This invention describes a fully automatic casting riser and gating cleaning device.

[0047] A fully automatic casting gate and riser cleaning device, adapted for cleaning the gate and riser of casting 500, includes a support frame 100, on which a hydraulic cylinder 110 is vertically connected. The fixed end of the hydraulic cylinder 110 is fixedly connected to the support frame 100, and a push block 200 is coaxially and fixedly connected to the telescopic end of the hydraulic cylinder 110. The push block 200 has two corresponding beveled sides and a pointed lower end. The support frame 100 also has push plates 300. In the prior art, two push plates 300 are connected to the support frame 100. Two push plates 300 are respectively attached to the two inclined surfaces of push block 200, forming triangular tips. When it is necessary to separate the gating and riser of casting 500, the triangular tips formed by the two push plates 300 are inserted into the preset groove at the connection between casting 500 and gating and riser. Then, the telescopic end of hydraulic cylinder 110 extends, driving push block 200 to move. Push block 200 pushes the two push plates 300, causing the triangular tips formed by the two push plates 300 to expand, thereby separating casting 500 from its gating and riser. Figures 8-9 The existing casting gating and riser cleaning equipment shown includes a wedge 600, a pointed iron 610, a hydraulic cylinder 620, and a piston rod 630. Both the wedge 600 and the pointed iron 610 have triangular tips. The triangular tip of the pointed iron 610 slides in contact with the interior of the triangular tip of the wedge 600. The end of the pointed iron 610 furthest from its triangular tip is fixedly connected to the piston rod 630 of the hydraulic cylinder 620. When the piston rod 630 of the hydraulic cylinder 620 extends or retracts, it drives the pointed iron 610 to push the wedge 600, thereby... The triangular tips of the wedge 600 are far apart to separate the risers and gating gates. However, in the prior art, the triangular tips of the wedge 600 are prone to reaction force when expanding. This reaction force can easily cause the pusher plate 300 to loosen momentarily, resulting in separation failure. Repeated separation is required, which is time-consuming and reduces work efficiency. Furthermore, the contact parts are in the same area for a long time, which will cause wear on the parts, resulting in the peeling and detachment of surface material, which will reduce the fitting accuracy, significantly shorten the service life of the equipment, and increase maintenance costs and downtime.

[0048] Based on this, to improve work efficiency and increase the service life of the equipment, the present invention elastically slides two push plates 300 on the support frame 100 in a preset direction, which is horizontal, and the two push plates 300 tend to move closer to each other. A chain plate is arranged around the outer periphery of the two push plates 300, and the chain plate can rotate around the outer periphery of the push plates 300. The chain plate includes multiple chain plate units 320, which are hinged end-to-end. Each chain plate unit 320 is provided with a wedge-shaped protrusion 321. Simultaneously, an adjustment component is provided on the inclined surface of the push block 200. The adjustment component is configured such that when the push block 200 pushes the two push plates 300 away from each other, the inclined surfaces on both sides of the push block 200 can push the chain plate units 321. The wedge-shaped protrusion 321 of the 20 causes the chain plate to rotate as a whole. When the chain plate rotates, it exerts a force to move the two push plates 300 into the preset groove of the connection between the casting 500 and the riser, thereby reducing the probability of the push plates 300 dislodging from the groove, thus saving time and improving work efficiency. Furthermore, when the adjusting component keeps the chain plate on the outer periphery of the push plates 300 when the two push plates 300 approach and reset, the outer periphery of the chain plate will rotate each time the riser on the casting 500 is separated, thereby changing the force position of the chain plate. This avoids the wear caused by the same position on the two push plates 300 being used for a long time in the prior art, and thus improves the service life of the equipment to a certain extent.

[0049] Specifically, the adjustment assembly in this embodiment includes multiple limiting plates 240 and multiple first elastic elements 250. The number of limiting plates 240 and the number of first elastic elements 250 are the same. All limiting plates 240 are hinged to the inclined surface of the push block 200, and the multiple limiting plates 240 are evenly distributed along the length direction of the inclined surface of the push block 200. Figure 4 and Figure 5 As shown, the hinge axes 241 of multiple limiting plates 240 are parallel to each other. Multiple first elastic elements 250 are respectively disposed between the multiple hinge limiting plates 240 and the inclined surfaces of the push block 200. Each first elastic element 250 is located below the hinge axis 241 of each limiting plate 240. The first elastic element 250 pushes up one end of the limiting plate 240 so that the limiting plate 240 abuts against the wedge-shaped protrusion 321 on the chain plate unit 320. When the push block 200 moves downward, the end of the push block 200 pushed up by the first elastic element 250 drives the wedge-shaped protrusion 321 to move together. The pusher moves step by step, allowing the chain plate to rotate around the outer periphery of the pusher plate 300. When the pusher block 200 moves upward, the two pusher plates 300 tend to move closer to each other. Therefore, the pusher plate 300 pushes the limiting plate 240 on the pusher block 200 to rotate around the hinge axis 241, thereby compressing the first elastic element 250. This causes the limiting plate 240 to slide relative to the wedge-shaped protrusion 321, thus ensuring that the chain plate does not rotate when the pusher block 200 moves upward as a whole. Only when the pusher block 200 moves upward as a whole can the chain plate rotate around the pusher plate 300.

[0050] It should be noted that, as Figure 5 As shown, in this embodiment, the upper end of the wedge-shaped protrusion 321 is a plane, and the side of the wedge-shaped protrusion 321 is an inclined surface. When the first elastic member 250 pushes one end of the limiting plate 240, one end of the limiting plate 240 abuts against the upper end of the wedge-shaped protrusion 321, and the side of the limiting plate 240 is close to the side of the wedge-shaped protrusion 321. Therefore, when the push block 200 moves upward, the limiting plate 240 will rotate around the hinge axis 241 under the action of the inclined side of the wedge-shaped protrusion 321 and compress the first elastic member 250, and cause the limiting plate 240 to slide with the inclined side of the wedge-shaped protrusion 321.

[0051] In a further embodiment, to enable the two push plates 300 to adapt to the slots of the riser and gating joints of castings 500 of various sizes, two sliding plates 330 are slidably disposed on the support frame 100 of the present invention. The two sliding plates 330 are parallel to the two push plates 300, and the two sliding plates 330 can slide along the length direction of the two push plates 300 to adjust the position of the two push plates 300. To enable the sliding plates 330 to move along the length direction of the push plates 300, each of the two sliding plates 330 in this embodiment is provided with a slide rail 331, which moves along the length direction of the sliding plates 330. Extending along the length direction, two first limiting slide rods 101 are provided on the support frame 100. The line connecting the two first limiting slide rods 101 is parallel to the push plate 300. The two first limiting slide rods 101 pass through the slide rail 331, thereby guiding the sliding plate 330 to slide. When the two sliding plates 330 drive the two push plates 300 to move obliquely upward, the distance between the lower ends of the two push plates 300 will increase. At this time, the push block 200 is configured as a telescopic structure, and the push block 200 shortens when the two push plates 300 move obliquely upward, thereby adapting to the distance between the lower ends of the two push plates 300.

[0052] It is understandable that when the distance between the lower ends of the two push plates 300 increases, it can accommodate larger slots, thereby increasing the range of applications of the equipment and enabling the equipment to remove risers and gatings of various sizes from the casting 500.

[0053] Specifically, to facilitate the connection between the two sliding plates 330 and the two push plates 300, two second limiting slide rods 332 are respectively provided on the two sliding plates 330. The line connecting the two second limiting slide rods 332 is parallel to the sliding plate 330. Two parallel limiting slide grooves 301 are respectively opened on the two push plates 300. The two limiting slide grooves 301 extend horizontally. The two second limiting slide rods 332 on the two sliding plates 330 are respectively located in the two limiting slide grooves 301 on the two push plates 300. At the same time, a second elastic element 350 is provided between the two push plates 300. The second elastic element 350 is a tension spring. The second elastic element 350 is used to pull the two push plates 300 closer together so that they can contact the inclined surface of the push block 200. When the push block 200 moves downward, the inclined surface of the push block 200 pushes the two push plates 300 away from each other, so that the two push plates 300 move along the limiting slide grooves 301.

[0054] It should be noted that, in order to realize the sliding function of the sliding plate 330, two telescopic rods 120 are provided on the support frame 100. One end of the two telescopic rods 120 is hinged to the support frame 100, and the other end of the two telescopic rods 120 is hinged to the upper end of the sliding plate 330. The two telescopic rods 120 extend and retract simultaneously, thereby driving the two sliding plates 330 to move simultaneously along the extension direction of the slide rail 331, and in turn driving the two push plates 300 to move synchronously to adjust the distance between the lower ends of the two push plates 300.

[0055] It should be noted that, in this embodiment, rollers 310 are rotatably provided at both ends of the two push plates 300. The rollers 310 are used to support the chain plates. The rollers 310 make rolling contact with the inner circumference of the chain plates, thereby replacing some of the sliding friction with rolling friction, thereby further reducing the friction force on the chain plates.

[0056] In a further embodiment, the push block 200 of the present invention includes a first connecting block 210, a second connecting block 220, and a third connecting block 230. One end of the first connecting block 210 is fixedly connected to the telescopic end of the hydraulic cylinder 110, and the other end of the first connecting block 210 is slidably connected to the second connecting block 220. The second connecting block 220 is slidably connected to the third connecting block 230. The third connecting block 230 has a pointed tip, and the pointed tip faces downward. In order to enable the push block 200 to extend and retract and adjust its overall length, a multi-stage telescopic cylinder 130 is provided inside the first connecting block 210. The fixed end of the multi-stage telescopic cylinder 130 is fixed inside the first connecting block 210. The multi-stage telescopic cylinder 130 has a first-stage telescopic end 131 and a second-stage telescopic end 132. The first-stage telescopic end 131 and the second-stage telescopic end 132 are coaxially arranged. 31 is axially slidably connected to the fixed end. The second-stage telescopic end 132 is axially slidably connected to the first-stage telescopic end 131. The first-stage telescopic end 131 is connected to the second connecting block 220, and the second-stage telescopic end 132 is connected to the third connecting block 230. When the multi-stage telescopic cylinder 130 shortens, it will first pull the second-stage telescopic end 132 to shorten, causing the third connecting block 230 to slide first. When the second-stage telescopic end 132 shortens to its limit, the third connecting block 230 stops sliding. Then the first-stage telescopic end 131 begins to shorten, and the first-stage telescopic end 131 drives the second connecting block 220 to slide. When the first-stage telescopic end 131 shortens to its limit, the second connecting block 220 stops sliding. When the multi-stage telescopic cylinder 130 extends, it will first push the second-stage telescopic end 132 to extend, and then push the first-stage telescopic end 131 to extend after extending to its limit.

[0057] It should be noted that the first connecting block 210, the second connecting block 220 and the third connecting block 230 in this invention all have inclined surfaces on their sides, and the aforementioned limiting plate 240 is only provided on the inclined surface of the side of the first connecting block 210. When the telescopic end of the hydraulic cylinder 110 extends, it pushes the first connecting block 210, the second connecting block 220 and the third connecting block 230 to move downwards synchronously, and the limiting plate 240 on the side of the first connecting block 210 pushes the chain plate to rotate.

[0058] like Figure 6As shown, to facilitate the sliding connection between the first connecting block 210, the second connecting block 220, and the third connecting block 230, a vertically extending first groove 211 is provided at the bottom of the first connecting block 210. One end of the second connecting block 220 is slidably disposed within the first groove 211. Two vertically extending first guide rails 212 are provided on the first connecting block 210, and two first guide rods 222 are provided at the upper end of the second connecting block 220. The two first guide rods 222 are slidably disposed within the two first guide rails 212, thereby... This allows the second connecting block 220 to slide stably along the first sliding groove 211. The bottom of the second connecting block 220 has a vertically extending second sliding groove 221, and the second connecting block 220 is provided with a vertically extending second guide rail 223. The upper end of the third connecting block 230 is provided with a second guide rod 231. When the third connecting block 230 is slidably disposed in the second sliding groove 221, the second guide rod 231 is slidably disposed in the second guide rail 223, thereby enabling the third connecting block 230 to slide stably along the second sliding groove 221.

[0059] In a further embodiment, the present invention provides cleaning roller brushes 340 at corresponding positions of the two sliding plates 330. The cleaning roller brushes 340 are made of wear-resistant material with a certain elasticity, and their outer peripheral surface is in close contact with the surface of the chain plate. When the chain plate rotates around the push plate 300, the surface of the chain plate moves relative to the cleaning roller brushes 340, and the dense bristles on the surface of the cleaning roller brushes 340 clean the surface of the chain plate in all directions.

[0060] Understandably, this structural design can efficiently remove various debris, dust, oil, and other impurities that adhere to the chain plates during operation. In particular, it can effectively remove small particles that tend to accumulate in the meshing parts of the chain plates by using the cleaning roller brush 340 to clean deep into the gaps. At the same time, it fundamentally avoids additional wear caused by these impurities due to compression and friction during the movement of the chain plates, effectively reducing contact wear between the chain plates and related components and extending the overall service life.

[0061] It should be noted that the installation position of the cleaning roller brush 340 can be adaptively adjusted according to the movement trajectory of the chain plate, ensuring that the cleaning operation can be completed in the return section of the chain plate, avoiding the re-adhesion of the cleaned impurities onto the working surface of the chain plate, and further improving the stability of the cleaning effect.

[0062] In a further embodiment, the present invention is also equipped with an automated conveying mechanism, specifically including a horizontally arranged conveyor frame 400. A conveyor belt 410 driven by a drive motor is mounted on the conveyor frame 400. The conveyor belt 410 is made of wear-resistant rubber and has anti-slip textures on its surface, enabling it to continuously and smoothly convey the castings 500 to be processed at a set speed. A six-axis industrial robotic arm 420 is fixedly installed on one side of the conveyor frame 400. Its base is rigidly connected to a pre-embedded part in the ground via high-strength bolts. The end effector of the robotic arm 420 is detachably connected to a support frame 100 via a flange. This connection structure allows for quick replacement of the appropriate support frame 100 according to different specifications of castings 500.

[0063] It should be noted that the robotic arm 420 integrates a vision positioning system. When the casting 500 on the conveyor belt 410 passes by, the vision sensor can capture the three-dimensional coordinates and posture information of the casting 500 in real time and transmit the data to the control system. After the control system quickly calculates the optimal working path through the algorithm, it drives the robotic arm 420 to move precisely according to the preset trajectory, so that the support frame 100 is precisely aligned with the position of the casting 500 on the conveyor belt 410. This ensures that the two push plates 300 on the support frame 100 can be inserted into the slot of the riser to be removed at a preset angle. In addition, the vision sensor can also obtain the size of the slot of the riser on the casting 500 and transmit the data to the control system. The control system controls the multi-stage telescopic cylinder 130 and the telescopic rod 120 to adjust the length of the two sliding plates 330 and the push block 200, thereby adapting to the slot of each riser of different sizes. Once the push plate 300 is in position, the control system issues a command to slowly extend the telescopic end of the hydraulic cylinder 110 according to the set thrust. The driving force is evenly transmitted to the two push plates 300 through the push block 200, and the two push plates 300 move away from each other. At the same time, the limiting plate 240 on the side of the first connecting block 210 of the push block 200 pushes the chain plate to rotate around the push plate 300, thereby achieving stable pushing and separation of the gating and riser.

[0064] By coordinating the conveyor belt 400 and the robotic arm 420, this invention constructs a complete automated processing line: the conveyor belt 410 continuously feeds the castings 500, while the robotic arm 420 performs positioning, gripping, and separation operations. The entire process allows for batch processing of the castings 500 without human intervention. Compared to the traditional manual operation mode, this automated system not only reduces the processing time per piece to one-third of the original time but also avoids damage to the castings 500 caused by uneven force during manual operation. Furthermore, it can operate 24 hours a day without interruption, significantly improving production efficiency and product qualification rate, making it particularly suitable for large-scale industrial production scenarios.

[0065] The specific working process of the fully automatic casting riser and gating cleaning equipment provided by the present invention will be described in conjunction with the above embodiments:

[0066] Feeding:

[0067] The casting 500 to be processed is continuously and smoothly conveyed by the conveyor belt 410 on the conveyor frame 400. The vision positioning system of the robotic arm 420 captures the three-dimensional coordinates, posture and gating gate size information of the casting 500, and transmits them to the control system. The control system calculates the optimal operation path, drives the robotic arm 420 to move the support frame 100 to the position of the casting 500 precisely, and adjusts the telescopic rod 120 and the multi-stage telescopic cylinder 130 according to the gate size, and adjusts the length of the two sliding plates 330 and the push block 200 so that the push plate 300 adapts to the gate size.

[0068] Separation:

[0069] The robotic arm 420 moves the support frame 100, precisely inserting the triangular tips formed by the two push plates 300 into the preset slots at the connection between the casting 500 and the riser. The control system instructs the extension end of the hydraulic cylinder 110 to slowly extend with a set thrust, pushing the first connecting block 210, the second connecting block 220, and the third connecting block 230 to move downwards synchronously. The inclined surface of the first connecting block 210 can push the two push plates 300 away from each other along the extension direction of the limiting slide groove 301 to expand and separate the connection between the riser and the casting. At the same time, the limiting plate 240 on the inclined surface of the first connecting block 210 will abut against the top of the wedge-shaped protrusion 321 of the chain plate unit 320, thereby driving the entire chain plate to rotate. When the chain plate rotates, it will generate a force that moves the two push plates 300 into the slot, thereby reducing the probability of the two push plates 300 dislodging from the slot.

[0070] During reset, the retraction end of the hydraulic cylinder 110 contracts, causing the first connecting block 210, the second connecting block 220, and the third connecting block 230 to move upward synchronously. The limiting plate 240 on the inclined surface of the first connecting block 210 rotates around the hinge shaft 241 under the action of the side inclined surface of the wedge-shaped protrusion 321 to compress the first elastic element 250. At this time, the limiting plate 240 slides against the side inclined surface of the wedge-shaped protrusion 321, ensuring that the chain plate does not rotate. This allows the two push plates 300 to move closer together and reset under the action of the second elastic element 350. Each time the two push plates 300 are inserted into the slot to separate the riser and gating system, the chain plate rotates, ensuring that different parts of the chain plate can be inserted into the slot, thus preventing wear caused by prolonged use of the same position on the chain plate.

[0071] clean:

[0072] When the chain plate rotates around the push plate 300, the cleaning roller brush 340 on the sliding plate 330 can clean the surface of the chain plate, thereby removing impurities from the surface and avoiding additional wear.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
