Description

Technical Field

[0001] This invention belongs to the field of other metal processing machinery manufacturing technology, specifically a burr removal device for stainless steel hose clamps. Background Technology

[0002] Stainless steel hose clamps are key accessories used to fasten flexible and rigid pipes. Made from high-quality stainless steel, they possess excellent corrosion resistance, high-temperature resistance, and aging resistance. They can quickly and effectively secure pipes and are widely used in pipe connection scenarios in the automotive, shipbuilding, machinery, and construction industries. Stainless steel hose clamps typically have several holes punched into their surface to enhance their structural flexibility and adaptability. They are then deburred from their surface and cut surfaces using a hose clamp deburring device.

[0003] A patent with publication number CN213004309U discloses a deburring device for stainless steel hose clamps, including a support plate and support legs. The support plate is a rectangular plate structure with support legs vertically positioned at its four bottom corners. A support frame is provided on the top of the support plate, and the support frame has an arch-shaped structure. An mounting component is installed at the center of the bottom surface of the top of the support frame. A third rotating motor is vertically installed inside the mounting component. A second connecting component is installed at the bottom of each of the two second sliders. A second grinding block is horizontally installed on the shaft at the output end of the second rotating motor. The second grinding block is located on one side of the support arc plate. A connecting rod is horizontally provided at the output end of the drive motor, and the free end of the connecting rod is installed on the side wall of the second rotating motor. When using the device, the stainless steel hose clamp to be processed is first fixed with a fixing clamp. Then, the user starts the third rotating motor, causing the first grinding block to grind the inner wall of the stainless steel hose clamp. The position can be adjusted during grinding. Then, the stainless steel hose clamp is fixed on the support arc plate, and the second rotating motor is started to grind the outer surface of the stainless steel hose clamp through the second grinding block.

[0004] The above-mentioned solution still has some problems in practical application. The existing stainless steel hose clamp burr removal device has obvious limitations in actual use. First, it only relies on the second grinding block to grind the two cut end faces of the stainless steel hose clamp. However, this single grinding method cannot effectively remove the burrs on the surface of the hose clamp. In the production process of stainless steel hose clamp, in order to enhance its structural flexibility, several holes are formed on the surface through the stamping process. However, during the punching process, the stainless steel strip undergoes plastic flow under the strong pressure of the mold. When the punch penetrates the stainless steel strip, the metal near the fracture surface will uncontrollably turn outward or tear towards the edge of the hole due to the tensile stress, thus forming burrs. These burrs are not only distributed on the cut end faces of the hose clamp, but also widely present in the edges of the holes. Therefore, grinding only the end faces of the stainless steel hose clamp can only deal with some burrs. It is powerless to deal with burrs in the edges of the holes and other parts, and cannot achieve a thorough deburring effect, which affects the quality of the hose clamp and its subsequent use.

[0005] Therefore, the present invention provides a burr removal device for stainless steel hose clamps. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a stainless steel hose clamp burr removal device, comprising a machine body, a fixed platform fixedly connected to one side of the machine body, a plurality of telescopic columns fixedly connected to the upper surface of the fixed platform, a compression spring sleeved on the circumferential surface of each telescopic column, a common pressing plate fixedly connected to the top of the plurality of compression springs, a fixed plate fixedly connected to the upper surface of the fixed platform, a first hydraulic cylinder fixedly connected to the top of the machine body, a hydraulic plate fixedly connected to the output end of the first hydraulic cylinder, and a grinding assembly provided on the upper surface of the fixed platform, the grinding assembly comprising a plurality of abrasive columns slidably disposed above the fixed platform, the plurality of abrasive columns being used for grinding the edges of the holes on the surface of the hose clamp plate;

[0008] The fixed plate is provided with a push assembly inside. The push assembly includes several push blocks that are elastically connected to the upper surface of the fixed plate. The push blocks are used to push out the stamped protrusions. The protrusions are the waste material generated after stamping the hose clamp plate.

[0009] An inclined plate is fixed to one side of the fixed plate, and the inclined plate guides the hose clamp plate to complete the grinding work.

[0010] Preferably, the polishing assembly further includes a first guide rail fixed to the upper surface of the fixed platform. The upper surface of the first guide rail is provided with a sliding groove. A lead screw is rotatably connected in the sliding groove. A slide plate is slidably connected to the circumferential surface of the lead screw. The slide plate is an electric push rod. A connecting plate is fixed to the top of the slide plate. An electric push rod is fixed to one side of the connecting plate. Two auxiliary rods are fixed to one side of the connecting plate. Several sliding blocks are slidably connected to the surfaces of the two auxiliary rods. A crossbar is fixed between every two sliding blocks. A sanding column is rotatably connected to the lower surface of the sliding block. The output end of the electric push rod is fixed to one of the sliding blocks.

[0011] Preferably, a positioning rod is fixedly connected to one side of the sliding block, a positioning frame is fixedly connected to one end of the positioning rod, a connecting strip is fixedly connected between every two positioning frames, a rotating rod is rotatably connected inside the sliding block, a rotating plate is fixedly connected to the top of the rotating rod, a positioning post is fixedly connected to the upper surface of the rotating rod, the positioning post is located inside the positioning frame, a base plate is fixedly connected to the bottom end of the rotating rod, and a frosted post is rotatably connected to one end of the base plate.

[0012] Preferably, during the stamping process, the stainless steel hose clamp plate is moved to the upper surface of the fixed plate by a conveyor. Then, the first hydraulic cylinder is activated, which drives the hydraulic plate at its bottom end. The hydraulic plate presses the pressing plate downward, and the pressing plate presses the telescopic column and the compression spring downward. Several punches are set on the lower surface of the pressing plate, so that the punches punch holes in the hose clamp plate. After the punching work is completed, the push assembly is automatically activated, which pushes the stamping waste to pop out, thereby assisting the punching.

[0013] Preferably, the pushing assembly further includes a plurality of first grooves formed inside the fixed plate, wherein a telescopic rod is fixedly connected to the first groove, a spring is sleeved on the circumferential surface of the telescopic rod, and a top block is fixedly connected to the top of the spring.

[0014] Preferably, after the punching operation is completed and the hydraulic plate is retracted, the pressing plate is reset under the action of the compression spring, and the punch also retracts. At this time, the top block is pushed out by the reset action of the spring, pushing out the waste material that was squeezed into the first groove during the punching process.

[0015] Preferably, after punching is completed, the lead screw in the first guide rail is started to rotate. The lead screw drives the slide plate to slide along the first guide rail. The slide plate drives the connecting plate to slide directly above the fixed plate. During the movement, the auxiliary component pushes the waste generated by punching away from the surface of the hose clamp plate. Then the slide plate moves directly above the punch, and the electric push rod is started to drive the connecting plate to move downward, so that the abrasive column is inserted into the punch for grinding.

[0016] Preferably, after the frosted column is inserted into the punch hole, the electric push rod is activated to perform reciprocating sliding work, pushing one of the sliding blocks, and then driving each sliding block to slide through the crossbar. The sliding block drives the rotating rod to move, and the rotating rod rotates with the assistance of the positioning post at its top. Specifically, the sliding of the sliding block causes the positioning post to slide back and forth under the limit of the positioning frame, thereby causing the rotating rod to rotate. The rotation of the rotating rod drives the base plate to rotate, and the rotation of the base plate drives the frosted column at the bottom to be ground along the edge of the punch hole.

[0017] Preferably, the auxiliary component includes an auxiliary plate fixed to one side of the slide plate, a push plate fixed to one side of the auxiliary plate, the push plate being a thin metal plate, an auxiliary groove formed on the lower surface of the auxiliary plate, an auxiliary roller rotatably connected within the auxiliary groove, a ring of sponge covering the surface of the auxiliary roller, a storage box fixed to the upper surface of the machine body, a connecting hose fixed to one side of the storage box, and one end of the connecting hose fixed to the auxiliary plate.

[0018] Preferably, during the process of the pusher plate of the auxiliary component pushing the waste, the pusher plate first scoops up the waste. Then, when the auxiliary plate moves out of the fixed plate, because the pusher plate is a thin metal plate, the waste will bend the pusher plate. Then the waste will slide down along the guide plate fixed to the upper surface of the machine body. A side plate is fixed to one side of the guide plate. In addition, during the movement of the auxiliary plate, the auxiliary roller on its lower surface will coat the surface of the hose clamp plate with alcohol. The alcohol is pressurized by the pressure pump in the storage tank and flows into the auxiliary plate along the connecting hose. A fixing strip is fixed to the middle of the guide plate. Fixing holes are opened on both sides of the fixing strip. Lubricating oil flows out of the fixing holes to lubricate the guide plate and guide the waste to slide down.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The stainless steel hose clamp burr removal equipment of the present invention achieves automation and high efficiency in the processing of stainless steel hose clamp plates by orderly combining punching, waste pushing and grinding processes. Its beneficial effects are significant. It not only improves production efficiency and reduces manual operation links and processing time, but also ensures the consistency and stability of product quality, effectively improves the finished product qualification rate of stainless steel hose clamp plates, and reduces the product defect rate caused by burrs and other problems. Finally, the hose clamp plates that have completed the grinding work smoothly enter the next processing flow or collection area under the guidance of the inclined plate.

[0021] 2. The stainless steel hose clamp burr removal device of the present invention uses a starting screw to drive a sliding plate, which moves a connecting plate above a fixed plate. During the movement, auxiliary components promptly push away waste material, ensuring a clean processing environment and preventing waste material from interfering with subsequent processes. Then, an electric push rod drives a grinding column to insert into the punch hole. The electric push rod pushes a sliding block, which, through a crossbar linkage, causes each rotating rod to rotate. This, in turn, drives the base plate and the grinding column to grind along the edge of the punch hole. In addition, the punch hole is elliptical, and the movement trajectory of the rotating rod is also elliptical. Therefore, the grinding action can fit the edge of the elliptical hole, effectively removing burrs, improving grinding quality, ensuring the precision and smoothness of the punched area of ​​the stainless steel hose clamp plate, and improving the overall product quality.

[0022] 3. The stainless steel hose clamp burr removal device of the present invention first scoops up the waste material with a push plate, and then pushes the waste material towards the guide plate. When the push plate moves above the guide plate, because the push plate is a thin metal sheet, it bends under the gravity of the waste material, and the waste material slides onto the guide plate. That is, it utilizes its own bendability to allow the waste material to slide along the guide plate. The guide plate also prevents the waste material from scattering. The auxiliary roller is coated with alcohol when the auxiliary plate moves, which can clean the surface of the hose clamp plate. The guide plate is equipped with a fixing strip to discharge lubricating oil, which not only reduces the resistance of the waste material sliding and avoids jamming, but also maintains the guide plate itself, extends its service life, improves the overall processing efficiency and quality, and ensures a smooth production process.

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] Example 1: As Figures 1 to 8 As shown in the embodiment of the present invention, a stainless steel hose clamp burr removal device includes a body 1, a fixed platform 2 fixedly connected to one side of the body 1, a plurality of telescopic columns 22 fixedly connected to the upper surface of the fixed platform 2, a compression spring 23 sleeved on the circumferential surface of each telescopic column 22, a single pressing plate 24 fixedly connected to the top of the plurality of compression springs 23, a fixed plate 21 fixedly connected to the upper surface of the fixed platform 2, a first hydraulic cylinder 3 fixedly connected to the top of the body 1, a hydraulic plate 31 fixedly connected to the output end of the first hydraulic cylinder 3, and a grinding assembly provided on the upper surface of the fixed platform 2. The grinding assembly includes a plurality of abrasive columns 225 slidably disposed above the fixed platform 2, and the plurality of abrasive columns 225 are used to grind the edges of the holes on the surface of the hose clamp plate 41.

[0039] The fixed plate 21 is provided with a push assembly, which includes a number of push blocks 230 elastically connected to the upper surface of the fixed plate 21. The push blocks 230 are used to push out the stamped protrusion 4. The protrusion 4 is the waste material generated after stamping the hose clamp plate 41.

[0040] An inclined plate 27 is fixed to one side of the fixed plate 21, and the inclined plate 27 guides the hose clamp plate 41 to complete the grinding work.

[0041] Specifically, existing stainless steel hose clamp burr removal devices have significant limitations in practical use. Firstly, they rely solely on the second grinding block to grind the two cut ends of the stainless steel hose clamp. However, this single grinding method cannot effectively remove burrs from the hose clamp surface. During the production of stainless steel hose clamps, several holes are formed on the surface through a stamping process to enhance their structural flexibility. However, during the punching process, the stainless steel strip undergoes plastic flow under the strong pressure of the die. When the punch penetrates the stainless steel strip, the metal near the fracture surface, due to tensile stress, will uncontrollably turn outward or tear towards the edge of the hole, thus forming burrs. These burrs are not only distributed on the cut ends of the hose clamp but also widely present at the edges of the holes. Therefore, grinding only the ends of the stainless steel hose clamp can only handle some burrs, and is powerless against burrs at the edges of the holes, failing to achieve a thorough deburring effect, thus affecting the quality and subsequent use of the hose clamp.

[0042] Therefore, the present invention sets up the above structure to solve the above problems. First, during the stamping process, the stainless steel hose clamp plate 41 is moved to the upper surface of the fixed plate 21 by conveying. Then, the first hydraulic cylinder 3 is started, and the first hydraulic cylinder 3 drives the hydraulic plate 31 at its bottom end. The hydraulic plate 31 squeezes the pressing plate 24 and moves it downward. The pressing plate 24 will squeeze the telescopic column 22 and the compression spring 23 downward. Several punches are set on the lower surface of the pressing plate 24, so that the punches punch holes in the hose clamp plate 41. After the punching work is completed, the push assembly is automatically started, which will push the stamping waste to pop out, thereby assisting the punching.

[0043] After the punching work is completed, the push assembly starts automatically. Since the top block 230 is elastically connected to the upper surface of the fixed plate 21, after the pressure generated by punching disappears, the top block 230 pops up with its own elastic potential energy, pushing the protrusion 4 (waste material) left on the hose clamp plate 41 after punching, so that it is removed from the hose clamp plate 41 and popped out, avoiding the waste material residue from affecting subsequent processing and product quality. This greatly assists the punching process and ensures the integrity and accuracy of punching.

[0044] The grinding process then begins. The grinding assembly starts operating, and several abrasive columns 225 slide along the top of the fixed platform 2. The abrasive columns 225 are then inserted into the punched holes. Their rough abrasive surfaces come into close contact with the edges of the holes on the hose clamp plate 41, generating friction. Through this continuous friction, the burrs generated after punching are gradually smoothed and removed, making the edges of the holes on the hose clamp plate 41 smooth and flat.

[0045] By combining punching, scrap pushing, and grinding processes in an orderly manner, the processing of stainless steel hose clamp plate 41 is automated and efficient, with significant benefits. It not only improves production efficiency and reduces manual operation and processing time, but also ensures the consistency and stability of product quality, effectively increases the finished product qualification rate of stainless steel hose clamp plate 41, and reduces the product defect rate caused by burrs and other problems. Finally, the hose clamp plate 41, after completing the grinding work, smoothly enters the next processing flow or collection area under the guidance of inclined plate 27.

[0046] like Figure 4 and Figure 5 As shown, the grinding assembly in this embodiment also includes a first guide rail 210 fixed to the upper surface of the fixed table 2. A groove 211 is formed on the upper surface of the first guide rail 210. A lead screw 212 is rotatably connected within the groove 211. A slide plate 213 is slidably connected to the circumferential surface of the lead screw 212. The slide plate 213 is an electric push rod. A connecting plate 214 is fixed to the top of the slide plate 213. An electric push rod 215 is fixed to one side of the connecting plate 214. Two auxiliary rods 216 are fixed to one side of the connecting plate 214. Several sliding blocks 217 are slidably connected to the surfaces of the two auxiliary rods 216. A crossbar 224 is fixed between every two sliding blocks 217. The lower surface of the slide block 213 is rotatably connected to a frosted column 225. The output end of the electric push rod 215 is fixedly connected to one of the sliding blocks 217. A positioning rod 218 is fixedly connected to one side of the slide block 213. A positioning frame 219 is fixedly connected to one end of the positioning rod 218. A connecting strip 221 is fixedly connected between every two positioning frames 219. A rotating rod 223 is rotatably connected inside the sliding block 217. A rotating plate 222 is fixedly connected to the top of the rotating rod 223. A positioning column 220 is fixedly connected to the upper surface of the rotating block 223. The positioning column 220 is located inside the positioning frame 219. A base plate 226 is fixedly connected to the bottom end of the rotating rod 223. A frosted column 225 is rotatably connected to one end of the base plate 226.

[0047] Specifically, after punching is completed, the lead screw 212 inside the first guide rail 210 is started to rotate. The lead screw 212 drives the slide plate 213 to slide along the first guide rail 210. The slide plate 213 drives the connecting plate 214 to slide directly above the fixed plate 21. During the movement, the auxiliary components push the waste generated by punching away from the surface of the hose clamp plate 41. Then the slide plate 213 moves directly above the punch, and the electric actuator is started to drive the connecting plate 214 to move downward, so that the abrasive column 225 is inserted into the punch for grinding.

[0048] After the frosted column 225 is inserted into the punch hole, the electric push rod 215 is activated and performs reciprocating sliding work, pushing one of the sliding blocks 217. Then, the crossbar 224 drives each sliding block 217 to slide. The sliding block 217 drives the rotating rod 223 to move. The rotating rod 223 rotates with the assistance of the positioning column 220 at its top. Specifically, the sliding of the sliding block 217 causes the positioning column 220 to slide back and forth under the limit of the positioning frame 219, thereby causing the rotating rod 223 to rotate. The rotation of the rotating rod 223 drives the base plate 226 to rotate. The rotation of the base plate 226 drives the rotating frosted column 225 at the bottom to polish along the edge of the punch hole.

[0049] By starting the lead screw 212 to drive the slide plate 213, the connecting plate 214 is moved above the fixed plate 21. During the movement, the auxiliary components promptly push away the waste material, ensuring a clean processing environment and preventing waste material from interfering with subsequent processes. Then, the electric push rod drives the abrasive column 225 to insert into the punch hole. The electric push rod 215 pushes the sliding block 217, which is linked by the crossbar 224 to rotate each rotating rod 223. This, in turn, drives the base plate 226 and the abrasive column 225 to grind along the edge of the punch hole. In addition, the punch hole is elliptical, and the movement trajectory of the rotating rod is also elliptical. Therefore, the grinding action can fit the edge of the elliptical hole, effectively removing burrs, improving grinding quality, ensuring the precision and smoothness of the punch hole of the stainless steel hose clamp plate 41, and improving the overall quality of the product.

[0050] like Figure 8 As shown, the push assembly in this embodiment also includes a plurality of first grooves 227 formed inside the fixed plate 21. A telescopic rod 228 is fixedly connected in the first groove 227. A spring 229 is sleeved on the circumferential surface of the telescopic rod 228. A top block 230 is fixedly connected to the top of the spring 229.

[0051] Specifically, after the punching work is completed, the hydraulic plate 31 is retracted, the pressing plate 24 is reset under the action of the compression spring 23, and the punch is also retracted. At this time, the top block 230 is pushed out by the reset action of the spring 229, pushing out the waste material squeezed into the first groove 227 during the punching process, thus achieving the effect of ensuring the continuity of processing and improving production efficiency and product quality.

[0052] Example 2: Figures 1 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the auxiliary component includes an auxiliary plate 5 fixedly attached to one side of the slide plate 213, a push plate 51 fixedly attached to one side of the auxiliary plate 5, the push plate 51 being a thin metal plate, an auxiliary groove 54 being provided on the lower surface of the auxiliary plate 5, an auxiliary roller 55 being rotatably connected in the auxiliary groove 54, a ring of sponge being sleeved on the surface of the auxiliary roller 55, a storage box 53 fixedly attached to the upper surface of the machine body 1, a connecting hose 52 fixedly attached to one side of the storage box 53, and one end of the connecting hose 52 being fixedly connected to the auxiliary plate 5.

[0053] Specifically, during the process of the pusher plate 51 of the auxiliary component pushing the waste, the pusher plate 51 will first scoop up the waste. Then, when the auxiliary plate 5 moves out of the fixed plate 21, because the pusher plate 51 is a thin metal plate, the waste will bend the pusher plate 51. Then the waste will slide down along the guide plate 25 fixed to the upper surface of the machine body 1. A side plate 26 is fixed to one side of the guide plate 25. In addition, during the movement of the auxiliary plate 5, the auxiliary roller 55 on its lower surface will coat the surface of the hose clamp plate 41 with alcohol. The alcohol is pressurized by the pressure pump in the storage tank 53 and enters the auxiliary plate 5 along the connecting hose 52. A fixing strip 28 is fixed to the middle of the guide plate 25. Fixing holes 29 are opened on both sides of the fixing strip 28. Lubricating oil flows out of the fixing holes 29 to lubricate the guide plate 25 and guide the waste to slide down.

[0054] The waste material is first scooped up by the push plate 51, and then the push plate 51 pushes the waste material toward the guide plate 25. When the push plate 51 moves above the guide plate 25, because the push plate 51 is a thin metal sheet, the push plate 51 bends under the gravity of the waste material, and the waste material slides onto the guide plate. That is, the waste material slides along the guide plate 25 by utilizing its own bendability. The guide plate 26 prevents the waste material from scattering. The auxiliary roller 55 is coated with alcohol when the auxiliary plate 5 moves, which can clean the surface of the hose clamp plate 41. The guide plate 25 is provided with a fixing strip 28 to discharge lubricating oil, which not only reduces the resistance of the waste material sliding and avoids jamming, but also maintains the guide plate 25 itself, extends its service life, improves the overall processing efficiency and quality, and ensures a smooth production process.

[0055] Working principle: First, during the stamping process, the stainless steel hose clamp plate 41 is moved to the upper surface of the fixed plate 21 by the conveyor. Then, the first hydraulic cylinder 3 is activated, which drives the hydraulic plate 31 at its bottom end. The hydraulic plate 31 presses the pressing plate 24 downward. The pressing plate 24 will press the telescopic column 22 and the compression spring 23 downward. Several punches are set on the lower surface of the pressing plate 24, so that the punches punch holes in the hose clamp plate 41. After the punching work is completed, the push assembly is automatically activated, which will push the stamping waste to pop out, thereby assisting the punching.

[0056] After punching is completed, the lead screw 212 in the first guide rail 210 is started to rotate. The lead screw 212 drives the slide plate 213 to slide along the first guide rail 210. The slide plate 213 drives the connecting plate 214 to slide directly above the fixed plate 21. During the movement, the auxiliary components push the waste generated by punching away from the surface of the hose clamp plate 41. Then the slide plate 213 moves directly above the punch. Then the electric actuator is started to drive the connecting plate 214 to move downward, so that the abrasive column 225 is inserted into the punch for grinding.

[0057] After the frosted column 225 is inserted into the punch hole, the electric push rod 215 is activated and performs reciprocating sliding work, pushing one of the sliding blocks 217. Then, the crossbar 224 drives each sliding block 217 to slide. The sliding block 217 drives the rotating rod 223 to move. The rotating rod 223 rotates with the assistance of the positioning column 220 at its top. Specifically, the sliding of the sliding block 217 causes the positioning column 220 to slide back and forth under the limit of the positioning frame 219, thereby causing the rotating rod 223 to rotate. The rotation of the rotating rod 223 drives the base plate 226 to rotate. The rotation of the base plate 226 drives the rotating frosted column 225 at the bottom to polish along the edge of the punch hole.

[0058] By starting the lead screw 212 to drive the slide plate 213, the connecting plate 214 is moved above the fixed plate 21. During the movement, the auxiliary components promptly push away the waste material, ensuring a clean processing environment and preventing waste material from interfering with subsequent processes. Then, the electric push rod drives the abrasive column 225 to insert into the punch hole. The electric push rod 215 pushes the sliding block 217, which is linked by the crossbar 224 to rotate each rotating rod 223. This, in turn, drives the base plate 226 and the abrasive column 225 to grind along the edge of the punch hole. In addition, the punch hole is elliptical, and the movement trajectory of the rotating rod is also elliptical. Therefore, the grinding action can fit the edge of the elliptical hole, effectively removing burrs, improving grinding quality, ensuring the precision and smoothness of the punch hole of the stainless steel hose clamp plate 41, and improving the overall quality of the product.

[0059] In addition, during the process of the auxiliary component push plate 51 pushing the waste, specifically, the push plate 51 will first scoop up the waste, and then when the auxiliary plate 5 moves out of the fixed plate 21, because the push plate 51 is a thin metal plate, the waste will bend the push plate 51, and then the waste will slide down along the guide plate 25 fixed to the upper surface of the machine body 1. A guide plate 26 is fixed to one side of the guide plate 25. In addition, during the movement of the auxiliary plate 5, the auxiliary roller 55 on its lower surface will coat the surface of the hose clamp plate 41 with alcohol. The alcohol is pressurized by the pressure pump in the storage tank 53 and enters the auxiliary plate 5 along the connecting hose 52. A fixing strip 28 is fixed to the middle of the guide plate 25. Fixing holes 29 are opened on both sides of the fixing strip 28. Lubricating oil flows out of the fixing holes 29 to lubricate the guide plate 25 and guide the waste to slide down.

[0060] The waste material is first scooped up by the push plate 51, and then the push plate 51 pushes the waste material toward the guide plate 25. When the push plate 51 moves above the guide plate 25, because the push plate 51 is a thin metal sheet, the push plate 51 bends under the action of the gravity of the waste material. That is, it uses its own bendability to let the waste material slide down the guide plate 25. The guide plate 26 prevents the waste material from scattering. The auxiliary roller 55 is coated with alcohol when the auxiliary plate 5 moves, which can clean the surface of the hose clamp plate 41. The guide plate 25 is provided with a fixing strip 28 to flow out lubricating oil, which not only reduces the resistance of the waste material sliding and avoids jamming, but also maintains the guide plate 25 itself, extends its service life, improves the overall processing efficiency and quality, and ensures a smooth production process.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
