Description

Technical Field

[0001] This invention relates to the field of synchronous belt processing technology, and in particular to a chamfering machine for processing highly elastic synchronous belts. Background Technology

[0002] During the production of synchronous belts, chamfering is required. The chamfering structure of synchronous belts can be referred to as a V-shaped transmission belt core chamfering device disclosed in Chinese Patent No. CN106239950B. It generally includes a core chamfering unit, which is used to chamfer the core of the transmission belt; a chamfering feed unit, which can make the core chamfering unit move closer to or further away from the core; and a core driving unit, which includes a core rotating wheel, a core driving motor, and a core tensioning wheel.

[0003] After the belt core is fitted onto the belt core rotating wheel, the belt core tensioning wheel tensions the belt core. Driven by the belt core drive motor, the belt core moves. As the belt core moves, the belt core chamfering unit chamfers the belt core.

[0004] The current method of loading and unloading cores is generally done manually, which is not only inefficient but also poses safety risks to personnel. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies that involve manual loading and unloading of strip workpieces, which are characterized by low efficiency and safety risks. It provides a chamfering machine for processing highly elastic synchronous belts and capable of automatically loading and unloading synchronous belts.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A chamfering machine for processing high-elasticity synchronous belts includes a frame, a product drive unit and a product chamfering unit located on the frame, the product drive unit including a drive wheel for driving the synchronous belt and a tension wheel that can be approached or moved away from the drive wheel, characterized in that it further includes:

[0008] The product loading unit is located directly in front of the product drive unit and can deliver one product at a time to the drive wheel.

[0009] The product receiving unit includes a string of rods, which are rotatably positioned between the product driving unit and the product feeding unit. The string of rods can be rotated to abut against the front of the drive wheel or rotated in the opposite direction to avoid interfering with the feeding of the product.

[0010] The product anti-detachment and unloading dual-effect mechanism includes a blocking component that extends and retracts on the outer ring wall of the drive wheel and prevents the product from falling off the drive wheel when extended, a pushing component that moves along the axial direction of the drive wheel and leaves a feeding gap with the blocking component that is greater than or equal to the product width to push the product out of the drive wheel, and a linkage drive component.

[0011] The linkage drive assembly includes a drive block elastically telescopically disposed at the center of the front side of the drive wheel and a first elastic member disposed inside the drive wheel to drive the drive block in a partially extended state. A first mating component is disposed between the drive block and the blocking component, which retracts synchronously with the retraction of the drive block and extends synchronously with the extension of the drive block. A second mating component is disposed between the drive block and the pushing component, which moves towards the front of the drive wheel with the retraction of the drive block and towards the rear of the drive wheel with the extension of the drive block. The pushing distance of the pushing component is much greater than the retraction distance of the drive block and the blocking component. The extension and retraction of the drive block is caused by the pressing or disengagement of the feeding rod. When the feeding rod rotates to abut against the front side of the drive wheel, the drive block is pressed and retracts into the drive wheel.

[0012] The above solution adds a product feeding unit, a product receiving unit, and a dual-effect product anti-detachment and unloading mechanism to the existing product drive unit and product chamfering unit. The product feeding unit can automatically and sequentially deliver products to the drive wheel. The product receiving unit can automatically receive the chamfered products and rotate to a position that does not interfere with the feeding of subsequent products. The dual-effect product anti-detachment and unloading mechanism works in conjunction with the product receiving unit without the need for an additional drive mechanism. When the feeding rod in the product receiving unit rotates to abut against the drive block, it can drive the blocking component to retract into the drive wheel and drive the pushing component to move forward to push the product out of the drive wheel and onto the feeding rod. When the feeding rod rotates to disengage from the drive block, the blocking component automatically extends partially outside the drive wheel and the pushing component retracts to reset. A feeding gap greater than or equal to the product width is reserved between the pushing component and the blocking component. The blocking component can prevent products from slipping off the drive wheel after subsequent products are fed. Therefore, the new chamfering machine can automatically achieve sequential feeding and automatic unloading, and the feeding and unloading structures do not interfere with each other.

[0013] Preferably, the blocking assembly includes baffles spaced circumferentially on the outer ring wall of the drive wheel, a first through groove on the drive wheel that can drive the baffles to reciprocate radially along the drive wheel, and a second elastic member inside the drive wheel that drives the baffles to partially extend out of the drive wheel.

[0014] Preferably, the first mating component includes a through groove provided in the drive wheel on the baffle plate along the direction parallel to the movement of the drive block, a mating inclined surface provided at the bottom of the through groove, and a drive rod that is inserted into the through groove. The lower end of the drive rod is recessed with a groove into which the mating inclined surface can be inserted. A pressing inclined surface that mates with the mating inclined surface is provided on the side of the groove near the front side of the drive wheel. The drive rod is connected to the drive block through a connecting ring and is arranged parallel to the extension and retraction direction of the drive block. When the baffle plate extends or retracts, the drive rod is always in the inserted state with the through groove.

[0015] With the above scheme, during the movement of the drive rod connected to the drive block, the pressing inclined surface on it cooperates with the mating inclined surface on the baffle plate to drive the baffle plate to extend and retract. During the extension and retraction of the baffle plate, the drive rod is always in the insertion state with the through groove, which can ensure that the drive rod is always driven and controlled by the baffle plate.

[0016] Preferably, a guide assembly is provided inside the drive wheel to allow the baffle plate to extend and retract radially along the drive wheel. The guide assembly includes a mounting ring protruding from the inner wall of the front side of the drive wheel with the drive block as the center, and a guide ring with an outward opening protruding from the outer ring wall of the mounting ring. The second elastic element is located inside the guide ring. As the baffle plate extends and retracts, the bottom of the baffle plate is always engaged with the guide ring.

[0017] Using the above scheme, the guide assembly is used to drive the baffle plate to always move radially along the drive wheel.

[0018] Preferably, the pushing assembly includes a pushing ring sleeved on the outer ring wall of the drive wheel and movable along the axial direction of the drive wheel, and a moving rod connected to the pushing ring and inserted into the rear side of the drive wheel along an axial direction parallel to the drive wheel. At least two moving rods are evenly spaced around the circumference of the drive wheel.

[0019] With the above scheme, the pusher ring is connected to the moving rod, and its moving direction is the same as that of the moving rod. The movement of the moving rod can drive the pusher ring to move.

[0020] Preferably, the second mating component includes a mounting rod protruding from the rear inner wall of the drive wheel and a lever hinged to the mounting rod. The two ends of the lever abut against the drive block and the moving rod, respectively. A mating groove is provided through the moving rod along its moving direction, through which the lever can pass and be pulled. One end of the lever has a hook, and in normal condition, the end with the hook is inclined upward and abuts against the end of the mating groove near the front side of the drive wheel. The downward inclined end of the lever abuts against the drive block. The distance from the hinge of the lever to the hook is much greater than the distance from the hinge of the lever to the end near the drive block. A third elastic element is provided on the moving rod, over the drive wheel, to drive the pusher ring to retract and reset in normal condition.

[0021] Using the above scheme, lever principle is utilized. When the drive block retracts, one end of the lever flips downwards, and the hooked end flips upwards. The hooked end passes through the mating groove and pulls the moving rod to move towards the front of the drive wheel. Since the distance from the hinged end of the lever to the hooked end is much greater than the distance from the hinged end to the end near the drive block, the forward distance of the moving rod is much greater than the moving distance of the baffle plate. Therefore, when the baffle plate retracts into the drive wheel, the ejector ring can push the product out of the drive wheel. When the drive block resets, the ejector ring retracts and resets under the action of the third elastic element.

[0022] Preferably, a first adjusting component is provided between the moving rod and the pusher ring to adjust the distance between the pusher ring and the baffle plate. The first adjusting component includes an adjusting rod protruding on the side of the pusher ring away from the front of the drive wheel. The moving rod is connected to the pusher ring through an "L"-shaped rod. The end of the "L"-shaped rod parallel to the moving rod has a recessed slot for the adjusting rod to be inserted. A waist-shaped groove extending along the moving direction of the pusher ring on the "L"-shaped rod communicates with the slot. A locking screw is fitted on the "L"-shaped rod and passes through the waist-shaped groove to be screwed to the adjusting rod.

[0023] Using the above solution, when the width of the synchronous belt products is different, the feeding distance between the pusher ring and the baffle plate can be adjusted by adjusting the distance between the pusher ring and the "L"-shaped rod.

[0024] Preferably, the product feeding unit includes a discharge rod spaced at the front of the drive wheel for products to be fitted onto it, a jacking component at the end of the discharge rod away from the drive wheel that can push the arranged products forward by one product width, and a loading and unloading cylinder at the lower end of the discharge rod near the drive wheel. When the piston rod of the loading and unloading cylinder extends, it can suspend a fallen product. The cylinder body of the loading and unloading cylinder is fixed to a conveying drive unit.

[0025] Using the above scheme, the discharge rod is used to discharge several products. After the operator suspends a row of products, the products can be gradually pushed forward by the width of one product under the drive of the jacking component. When a product falls, it will fall onto the extended loading and unloading cylinder. Under the drive of the conveying drive unit, the loading and unloading cylinder carries the product and moves. When the loading and unloading cylinder moves to the drive wheel until the cylinder body abuts against the baffle plate, the loading and unloading cylinder retracts, and the product can fall directly and be suspended on the product spacing of the drive wheel.

[0026] Preferably, the frame is equipped with a guide component that guides the product to facilitate the alignment of the product's chamfering unit. The guide component is a guide cylinder, and the piston rod end of the guide cylinder is connected to an assembly rod. A baffle is connected to the assembly rod, and the distance between the baffle and the guide cylinder body is equal to the width of the product. An adjustment mechanism is provided between the guide cylinder and the baffle to adjust the distance between them and always maintain the product's stable tension.

[0027] Using the above solution, when the piston rod of the guide cylinder extends, the distance between the baffle and the cylinder body is large. The falling product will be between the cylinder body and the baffle before tensioning. As the tensioning wheel descends, the product is in a tensioned state. After the guide cylinder retracts, the distance between the baffle and the cylinder body is exactly the width of the product. As the drive wheel rotates, the product moves along the guide of the guide cylinder. Therefore, the chamfering unit only needs to be aligned with the guide cylinder to ensure the accuracy of the chamfering.

[0028] Preferably, the adjusting mechanism includes a tensioning shaft protruding from the cylinder body of the guide cylinder and perpendicularly inserted into the baffle, the mounting rod being a stud, a through hole provided on the baffle for the stud to pass through, and locking nuts provided on the stud on both sides of the baffle.

[0029] Using the above solution, when the width of the product changes, the distance between the baffle and the cylinder body of the guide cylinder needs to be adjusted accordingly. The engagement of the stud and the locking nut can lock the baffle after adjustment. The tensioning shaft and the baffle guide engagement ensure that the product is tensioned on the tensioning shaft with the same diameter, so as to ensure the accuracy of product movement and chamfering.

[0030] This invention, by adopting the above technical solutions, has significant technical effects: Based on the existing product driving unit and product chamfering unit, a product feeding unit, a product receiving unit, and a dual-effect product anti-detachment and unloading mechanism are added. The product feeding unit can automatically and sequentially deliver products to the driving wheel. The product receiving unit can automatically receive the chamfered products and rotate it so as not to interfere with the feeding of subsequent products. The dual-effect product anti-detachment and unloading mechanism works in conjunction with the product receiving unit, achieving the desired effect without the need for an additional driving mechanism. When the feeding rod in the product receiving unit rotates... When the machine rotates to the drive block, it can drive the blocking component to retract into the drive wheel and drive the pushing component to move forward to push the product out of the drive wheel and set it precisely on the feeding rod. When the feeding rod rotates to disengage from the drive block, the blocking component automatically extends partially out of the drive wheel and the pushing component retracts to reset. A feeding gap greater than or equal to the product width is reserved between the pushing component and the blocking component. The blocking component can prevent the product from slipping off the drive wheel after subsequent products are fed. Therefore, the new chamfering machine can automatically achieve feeding and unloading one by one without interference between the feeding and unloading operations. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0043] Example

[0044] A chamfering machine for processing high-elasticity synchronous belts, as described in the reference. Figures 1-10 As shown, it includes a frame 1, a product driving unit, a product chamfering unit, a product feeding unit, and a product receiving unit located on the frame 1.

[0045] Reference Figures 1-4As shown, the product drive unit includes a drive wheel 2 for driving the synchronous belt product to move and a tension wheel 3 that can approach or move away from the drive wheel 2. The drive wheel 2 is rotatably mounted on the frame 1. A first drive motor 5 for driving the drive wheel 2 to rotate is mounted on the frame 1. The tension wheel 3 is rotatably mounted on a lifting plate. The lifting plate is longitudinally guided to rise and fall on the frame 1. A lifting cylinder (not shown) for driving the tension wheel 3 to rise and fall is mounted inside the frame 1.

[0046] The chamfering unit of the product uses existing technology, and this application does not make any improvements to it. Specifically, it includes a tool holder 7 that can move in three axes (XYZ) and a chamfering tool 8 located in front of the tool holder 7.

[0047] Reference Figure 2 As shown, the product feeding unit includes a discharge rod 9 spaced apart in front of the drive wheel 2, on which products can be fitted. The upper surface of the discharge rod 9 is a raised arc surface to facilitate smooth product movement. At the end of the discharge rod 9 away from the drive wheel 2, there is a pushing component 10 that can push the arranged products forward by one product width. The pushing component 10 is an electric push rod or a through-type linear screw stepper motor. In this embodiment, the latter is used. At the lower end of the discharge rod 9, near the drive wheel 2, there is a loading and unloading cylinder 15. When the piston rod of the loading and unloading cylinder 15 extends, it can suspend a fallen product. The cylinder body of the loading and unloading cylinder 15 is fixed to a conveying drive unit 11. The conveying drive unit 11 is a conveying cylinder. A guide block 13 with a guide hole is protruding on the lower end surface of the discharge rod 9. A guide rod 12 is guided and fitted in the guide hole. The end of the guide rod 12 and the end of the piston rod of the conveying cylinder are synchronously fixed to a mounting block. The loading and unloading cylinder 15 is fixed to the mounting block.

[0048] A guide component is provided on frame 1 to guide the product and facilitate the alignment of the product chamfering unit, as shown in the reference. Figures 5-6 As shown, the guiding component is a guide cylinder 16. An assembly rod is connected to the piston rod end of the guide cylinder 16, and a baffle 17 is connected to the assembly rod. The distance between the baffle 17 and the cylinder body of the guide cylinder 16 is equal to the width of the product. An adjustment mechanism is provided between the guide cylinder 16 and the baffle 17 to adjust the distance between them and maintain stable tension of the product. The adjustment mechanism includes a tensioning shaft 20 protruding from the cylinder body of the guide cylinder 16 and perpendicularly inserted into the baffle 17. The assembly rod is a stud 18, and a... A through hole is provided for the stud 18 to pass through. Locking nuts 19 are provided on both sides of the baffle 17 on the stud 18. When the width of the product changes, the distance between the baffle 17 and the cylinder body of the guide cylinder 16 needs to be adjusted accordingly. The cooperation between the stud 18 and the locking nuts 19 can lock the baffle 17 after adjustment. The tensioning shaft 20 is guided to the baffle 17. Changes in the distance between the baffles 17 can ensure that the product is tensioned on the tensioning shaft 20 with the same diameter, so as to ensure the accuracy of product movement and chamfering.

[0049] The guide cylinder 16 is fixed on an adjusting block 21, and in combination Figure 10 As shown, a slot for the adjustment block 21 to move is provided on the frame 1. An adjustment locking mechanism is provided between the slot and the adjustment block 21. The adjustment locking mechanism includes a rack 42 provided on one side of the adjustment block 21 along its moving direction, a receiving groove provided on the inner wall of the slot, and a toothed block 43 elastically telescopically provided in the receiving groove that meshes with the rack 42 when extended. A pull rod 44 extending out of the frame 1 is provided at the end of the rack 42 away from the rack 42. A pull block 45 is provided at the end of the pull rod 44. A fourth elastic element 46 is sleeved on the pull rod 44, with both ends elastically abutting against the bottom of the receiving groove and the toothed block 43. The fourth elastic element is a spring. By pulling the pull block 45, the toothed block 43 can be driven to disengage from the rack 42. At this time, the adjustment block 21 can be moved to adjust the position of the guide cylinder 16.

[0050] The product receiving unit includes a series of feed rods 4, as shown in the reference. Figures 1-2 As shown, the feeding rod 4 is a straight rod or an arc-shaped rod with an incline. In this embodiment, it is an arc-shaped rod. The upper end of the feeding rod 4 is provided with a guide slope 41, and the lower end of the feeding rod 4 is connected to a vertical rotating shaft. The rotating shaft is connected to a second drive motor 6. Under the drive of the second drive motor 6, the feeding rod 4 can rotate counterclockwise to abut against the front side of the drive wheel 2 or rotate clockwise to not interfere with the feeding of the product feeding unit. In this embodiment, the forward and reverse rotation angle of the feeding rod 4 is 120°.

[0051] A dual-effect product anti-detachment and unloading mechanism is installed on drive wheel 2, as shown in the reference. Figures 6-9 As shown, the drive wheel 2 in this embodiment is hollow inside. The product anti-detachment and unloading dual-effect mechanism includes a blocking component that extends and retracts on the outer ring wall of the drive wheel 2 and can prevent the product from falling off the drive wheel 2 when it extends; a pushing component that moves along the axial direction of the drive wheel 2 and can leave a feeding gap with the blocking component that is greater than or equal to the product width to push the product out of the drive wheel 2; and a linkage drive component.

[0052] The blocking assembly includes four baffle plates 23 circumferentially spaced on the outer ring wall of the drive wheel 2, a first through groove 231 on the drive wheel 2 that can drive the baffle plates 23 to reciprocate radially along the drive wheel 2, and a second elastic member 39 inside the drive wheel 2 that drives the baffle plates 23 to partially extend out of the drive wheel 2.

[0053] The feeding assembly includes a feeding ring 22 sleeved on the outer ring wall of the drive wheel 2 and movable along the axial direction of the drive wheel 2, and a moving rod 28 connected to the feeding ring 22 and inserted into the rear side of the drive wheel 2 along the axial direction parallel to the drive wheel 2. At least two moving rods 28 are evenly spaced around the circumference of the drive wheel 2. In this embodiment, four moving rods 28 are provided.

[0054] The linkage drive assembly includes a drive block 24 elastically telescopically disposed at the center of the front side of the drive wheel 2, and a first elastic member 31 disposed inside the drive wheel 2 to drive the drive block 24 in a partially extended state. A mounting seat 32 protrudes from the center of the rear inner wall of the drive wheel 2. One end of the mounting seat 32 near the front side of the drive wheel 2 has a recessed mating groove 29 for partial insertion of the drive block 24. The first elastic member 31 is a spring with both ends fixedly connected to the bottom of the mating groove 29 and the drive block 24, respectively. A first mating component is disposed between the drive block 24 and the moving rod 28, which retracts synchronously with the retraction of the drive block 24 and extends synchronously with the extension of the drive block 24. The components include a through groove 231 provided on the baffle plate 23 within the drive wheel 2 along the direction parallel to the movement of the drive block 24, a mating inclined surface 232 provided at the bottom of the through groove 231, and a drive rod 40 that is inserted into the through groove 231. The lower end of the drive rod 40 is recessed with a groove 41 into which the mating inclined surface 232 can be inserted. On the side of the groove 41 near the front of the drive wheel 2, there is a pressing inclined surface 411 that mates with the mating inclined surface 232. The drive rod 40 is connected to the drive block 24 through a connecting ring 47 that is vertically sleeved and fixed on the drive block, and the extension and retraction directions of the drive rod 40 and the drive block 24 are parallel. When the baffle plate 23 extends or retracts, the drive rod 40 is always in the inserted state with the through groove 231.

[0055] A guide assembly is provided inside the drive wheel 2, which allows the baffle plate 23 to extend and retract radially along the drive wheel 2. The guide assembly includes a mounting ring 37 protruding from the inner wall of the front side of the drive wheel 2 with the drive block 24 as the center and extending to the rear side of the drive wheel 2, and a guide ring 38 with an outward opening protruding from the outer ring wall of the mounting ring 37. The second elastic member 39 is a spring and is located inside the guide ring 38. The two ends of the second elastic member 39 are fixedly connected to the bottom of the baffle plate 23 and the guide ring 38, respectively. As the baffle plate 23 extends and retracts, the bottom of the baffle plate 23 is always engaged with the guide ring 38.

[0056] A second mating component is provided between the drive block 24 and the pusher assembly. As the drive block 24 retracts, the pusher ring 22 moves towards the front of the drive wheel 2; as the drive block 24 extends, the pusher ring 22 moves towards the rear of the drive wheel 2. (Refer to...) Figures 8-9As shown, the second mating component includes a mounting rod 34 protruding from the rear inner wall of the drive wheel 2 and a lever 35 hinged to the mounting rod 34. The two ends of the lever 35 abut against the drive block 24 and the moving rod 28, respectively. A mating groove 29 is provided through the moving rod 28 along its moving direction, through which the lever 35 can pass and pull it to move. One end of the lever 35 has a hook 36, and in the normal state, the end with the hook 36 is inclined upward and abuts against the end of the mating groove 29 near the front side of the drive wheel 2. The downward inclined end of the lever 35 abuts against the connecting ring 47. The distance from the hinge of the lever 35 to the end of the hook 36 is much greater than the distance from the hinge of the lever 35 to the end of the connecting ring. A third elastic element 33, which is a spring, is provided on the moving rod 28 around the drive wheel 2 to drive the pusher ring 22 to retract and reset in the normal state.

[0057] Due to the setting of lever 35, the pushing distance of pusher ring 22 is much greater than the retraction distance of drive block 24 and blocking component. The extension and retraction of drive block 24 is subjected to the pressing or disengagement of feed rod 4. When feed rod 4 rotates to abut against the front side of drive wheel 2, guide slope 41 is located on the side away from drive block 24 and feed rod 4 just presses against drive block 24 and pushes drive block 24 to retract until the end is flush with the front side of drive wheel 2.

[0058] To accommodate products of different widths, a first adjusting component is provided between the moving rod 28 and the pusher ring 22 to adjust the material feeding distance between the pusher ring 22 and the baffle plate 23. The first adjusting component includes an adjusting rod 30 protruding on the side of the pusher ring 22 away from the front of the drive wheel 2. The moving rod 28 is connected to the pusher ring 22 through an "L"-shaped rod 25. One end of the "L"-shaped rod 25 parallel to the moving rod 28 has a recessed slot for the adjusting rod 30 to be inserted. An oblong groove 26 extending along the moving direction of the pusher ring 22 on the "L"-shaped rod 25 communicates with the slot. A locking screw 27 is fitted on the "L"-shaped rod 25 and passes through the oblong groove 26 to be screwed to the adjusting rod 30.

[0059] The first drive motor 5, the second drive motor 6, the lifting cylinder, the control component that controls the chamfering blade 8 to move along the XYZ axis, the jacking component 10, the loading and unloading cylinder 15, the conveying cylinder, the guide cylinder 16, etc., mentioned above are all connected to a PLC, and the opening and closing of each component is realized by the existing logic programming of the PLC.

[0060] The partial steps of using the above-mentioned chamfering machine are as follows:

[0061] 1. Discharge: The operator hangs a number of synchronous belt products one by one on the discharge rod 9 until the frontmost product is flush with the end of the discharge rod 9 near the drive wheel 2, and the products behind are directly attached to the top end of the top feeding component 10.

[0062] 2. Hanging: When the loading and unloading cylinder 15 is in the extended state, the pushing component 10 presses against the distance of one component width, and a product falls and is suspended on the extended piston rod of the loading and unloading cylinder 15.

[0063] 3. Feeding: The guide cylinder 16 is in the extended state, the conveying cylinder extends until the cylinder body of the loading and unloading cylinder 15 abuts against the front side of the baffle plate 23; the loading and unloading cylinder 15 retracts, the product is suspended on the drive wheel 2, the drive wheel 2, the tension wheel 3 and the tension shaft 20 are located inside the product and the product is located at the feeding gap between the baffle plate 23 and the unloading plate.

[0064] 4. Tensioning: Guide cylinder 16 retracts, tensioning wheel 3 descends, and the product is in a tensioned state;

[0065] 5. Chamfering: The first drive motor 5 drives the drive wheel 2 to rotate. The product moves under the guidance of the guide cylinder 16. The chamfering blade 8 approaches and its lower end is in contact with the upper end of the baffle 17. The movement of the product drives the chamfering blade 8 to chamfer the product evenly. In this embodiment, the chamfering blade 8 has a 45° angle. Different chamfering blades 8 can be replaced with different chamfering blades for different chamfering angles.

[0066] 6. Unloading: The chamfering blade 8 retracts first, then the guide cylinder 16 extends, and further, the tensioning wheel 3 rises, the product is in a relaxed state, and finally, the feeding rod 4 rotates counterclockwise to press against the drive block 24 until the drive block 24 retracts to be flush with the front side of the drive wheel 2. At this time, the baffle plate 23 retracts into the drive wheel 2 and the pusher ring 22 presses against the front side of the drive wheel 2. The product slides off the drive wheel 2 and is threaded onto the feeding rod 4 along the guide slope 41. The product slides down the inclined feeding rod 4 to the bottom of the feeding rod 4.
