Description

Technical Field

[0001] The present application relates to the technical field of die-cutting machines, and in particular to a waste clearing device for die-cutting machines. Background Art

[0002] The die-cutting machine generally applies a certain amount of pressure through the embossing plate to cut the printed product or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding.

[0003] At present, during the die-cutting process of the die-cutting machine, there is a certain intermittent connection between the waste generated by die-cutting and the product. Therefore, it is necessary to push the waste away from the product completely through the waste cleaning needle to realize the waste cleaning process.

[0004] However, since the waste cleaning needle generally adopts a vertical movement method to clean the waste on the product, when cleaning structures such as die-cut holes, it is easy for the waste to still be partially connected to the product after the waste cleaning needle passes through the die-cut hole, affecting the waste cleaning effect.

[0005] In the above-mentioned related technologies, there is a defect that the waste cleaning effect of the die-cutting machine is not good. Summary of the invention

[0006] In order to improve the waste cleaning effect of a die-cutting machine, the present application provides a waste cleaning device for a die-cutting machine.

[0007] The die-cutting machine waste removal device provided in this application adopts the following technical solution: A waste removal device for a die-cutting machine comprises: a supporting mechanism, comprising a supporting frame and a supporting shell, the supporting shell being mounted on the supporting frame so that the supporting shell is spaced apart from the ground; a lifting mechanism being arranged on the supporting shell; a waste removal mechanism connected to the lifting mechanism, the lifting mechanism driving the waste removal mechanism to move vertically, the waste removal mechanism comprising an upper moving member, a lower bearing member and a plurality of waste removal members, the upper moving member being transmission-connected to the lifting mechanism so that the lifting mechanism drives the upper moving member to move vertically, a plurality of waste removal members being arranged on the lower side of the upper moving member, the lower bearing member being arranged on the supporting shell, and the lower bearing member being arranged on the upper moving member The upper movable member is provided with a plurality of cleaning holes, the cleaning holes being arranged corresponding to the cleaning members so that the cleaning members can pass through the cleaning holes; a scraping mechanism comprising a connecting assembly and a scraping plate, the connecting assembly being transmission-connected to the upper movable member and the scraping plate, the scraping plate being connected to the lower side of the lower movable member, the upper surface of the scraping plate sliding relative to the lower surface of the lower movable member, the scraping plate being able to move to the lower side of the lower movable member or to one side of the lower movable member, so that the upper movable member moves upward to drive the scraping plate to move downward to drive the scraping plate to move toward one side of the lower movable member.

[0008] By adopting the above technical solution, the support frame provides support for the support shell, so that the support shell can be spaced apart from the ground, so that waste can be collected under the support shell; the lifting mechanism is used to connect the support shell and the upper moving member, so that the upper moving member can move vertically, and a lower bearing member is arranged below the upper moving member, and the lower bearing member is arranged on the support shell, and is used to carry the die-cut products. The vertical movement of the upper moving member drives the waste cleaning member on the lower side to pass through the waste cleaning hole on the lower bearing member, so that the waste at the corresponding position on the product can be pushed downward to the lower side of the lower bearing member to achieve waste cleaning; due to the risk of waste adhesion to the product, the upper moving member and the scraping plate are connected by a connecting assembly, and when the upper moving member moves up, the scraping plate is driven to scrape the lower side of the lower bearing member at the same time, so as to cut off the adhesion between the waste and the product and optimize the cleaning effect of the waste; when the upper moving member moves down to clean the waste, the scraping plate is moved to one side of the lower bearing member to avoid the waste cleaning member and avoid collision with the waste cleaning member to affect the reliability of waste cleaning.

[0009] Optionally, the lifting mechanism includes a telescopic part, a connecting frame and a sleeve part, the fixed end of the telescopic part is connected to the top of the support shell, the movable end of the telescopic part is vertically telescopic, the movable end of the telescopic part is connected to the connecting frame, the upper movable part is connected to the connecting frame, the outer periphery of the sleeve part is connected to the connecting frame, a support column is provided in the support shell, and the sleeve part is slidably sleeved on the support column.

[0010] By adopting the above technical solution, the telescopic part provides a power source, the connecting frame realizes the connecting function, and the cooperation between the sleeve part and the support column can optimize the guiding effect, so that the telescopic part drives the upper moving part to realize vertical movement through the connecting frame and the sleeve part, thereby reducing the risk of horizontal deflection of the upper moving part, which causes inaccurate alignment of the waste cleaning part and the waste cleaning hole, thereby affecting the waste cleaning effect.

[0011] Optionally, the telescopic member is connected to the center of the connecting frame, and a plurality of the support columns and the sleeve members are provided, the support columns correspond to the sleeve members, and the sleeve members are evenly distributed around the circumference of the connecting frame.

[0012] By adopting the above technical solution, the cooperation of multiple sleeve parts and multiple support columns can improve the positioning and guiding accuracy. At the same time, it can improve the reliability of support, help achieve force balance, and make the upper moving part move vertically while maintaining the horizontality, so that several waste cleaning parts on the lower side of the upper moving part can be accurately inserted into the corresponding waste cleaning holes, avoiding the waste cleaning effect being affected by the deflection of the upper moving part in the vertical and horizontal directions.

[0013] Optionally, a detection mechanism is further included, the waste cleaning part includes a first waste cleaning needle and a second waste cleaning needle, the length of the first waste cleaning needle is greater than the length of the second waste cleaning needle, the first waste cleaning needle is distributed at the peripheral positions of a plurality of the second waste cleaning needles, the detection mechanism is arranged between the upper moving part and the first waste cleaning needle, and the detection mechanism is used to detect the abutment force of the first waste cleaning needle.

[0014] By adopting the above technical solution, the lower end of the first waste cleaning needle can first cooperate with the lower supporting member to pre-judge the alignment of the second waste cleaning needle and the waste cleaning hole. If the detection mechanism detects that the abutment force of the first waste cleaning needle is greater than the preset value, it means that the waste cleaning part has insufficient alignment and needs to be adjusted; if the detection mechanism detects that the abutment force of the first waste cleaning needle is less than the preset value, the alignment of the waste cleaning part is good, and the waste can be cleaned by continuing to move the waste cleaning part downward; because the first waste cleaning needle is arranged on the periphery of the second waste cleaning needle, it can be easily replaced after the first waste cleaning needle collides with the lower supporting member and is damaged, thereby reducing the difficulty of disassembly and assembly.

[0015] Optionally, the waste cleaning mechanism further includes a pressing piece and an elastic piece, one end of the elastic piece is connected to the upper moving piece, and the other end of the elastic piece is connected to the pressing piece, so that the pressing piece is arranged below the upper moving piece, and a plurality of through holes are provided on the pressing piece, and the through holes correspond to the waste cleaning piece, and a plurality of blocking parts are provided on the inner circumferential wall of the through hole, and the blocking part extends from the inner circumferential wall of the through hole toward the center of the through hole, and is used to reduce the area of ​​the through hole, and the blocking part is used to block the waste from passing through the waste cleaning hole and moving upward, and the blocking part is flexible so that the waste cleaning piece can push open the blocking part and pass through the through hole.

[0016] By adopting the above technical solution, when the upper moving part moves downward, the pressing part connected by the elastic part can contact the product before the waste cleaning part, thereby pressing the product to fix the product, so that the waste cleaning part can pass through the through hole to push the waste to the lower side of the waste cleaning hole, thereby optimizing the waste cleaning effect; when the upper moving part moves upward, since the inner peripheral wall of the through hole is provided with a blocking part, the waste cleaning part can push the flexible blocking part to move upward, but since the blocking part reduces the area of ​​the through hole, and the area of ​​the through hole is the same as the area of ​​the waste, the waste can be blocked under the pressing part, thereby reducing the risk of the waste affecting the cleaning effect as the waste cleaning part moves upward.

[0017] Optionally, the connecting assembly includes a first rack, a first gear, a connecting shaft and a second gear, the first rack is connected to the upper moving member, the first rack extends vertically, the first gear meshes with the first rack, the connecting shaft connects the first gear and the second gear, the second gear is arranged below the scraping plate, and a second rack is provided on the lower side of the scraping plate, the second rack meshes with the second gear, so that the vertical movement of the upper moving member drives the scraping plate to move horizontally.

[0018] By adopting the above technical solution, the vertical movement of the upper movable member drives the first rack to move vertically, thereby causing the first gear to rotate, and the second gear to rotate through the connection of the connecting shaft. The second rack meshes with the second gear, and then the second rack moves horizontally, so that the scraping plate can move horizontally under the lower supporting member, so as to cut off the waste materials that are adhered to the product and optimize the waste cleaning effect.

[0019] Optionally, the connecting assembly further comprises an extension member, the extension member extends in a width direction perpendicular to the conveying direction in a horizontal plane, and the upper end of the first rack is connected to the extension member, so that the first rack is arranged on one side of the upper moving member.

[0020] By adopting the above technical solution, the extension member enables the first rack and the first gear to be arranged on one side of the upper moving member and the lower bearing member, thereby reducing the risk of interference.

[0021] Optionally, the connecting shaft is rotatably connected to the supporting shell, and the first gear and the second gear are horizontally spaced and connected to the connecting shaft.

[0022] By adopting the above technical solution, the connecting shaft can rotate relative to the supporting shell, so that the rotation of the first gear can drive the connecting shaft to rotate, and then drive the second gear to rotate, thereby realizing transmission from the first rack to the second rack; and through the connection of the connecting shaft, the second gear can be arranged below the second rack to achieve meshing.

[0023] Optionally, two scraping mechanisms are provided, and the two scraping mechanisms are symmetrically arranged on both sides of the axis of the lower carrier, and the two first racks are arranged opposite to each other.

[0024] By adopting the above technical solution, two symmetrically arranged scraping mechanisms can reduce the length of the scraping plate along the conveying direction, avoid the scraping plate extending too long horizontally when the scraping plate moves to one side of the lower carrier and affecting the reliability, and can also reduce the risk of interference with other structures.

[0025] Optionally, a slide groove is provided on the lower side of the lower bearing member, and a sliding block is provided on the upper side of the scraping plate, and the sliding block is slidably connected to the slide groove.

[0026] By adopting the above technical solution, the scraping plate can be slidably connected to the lower side of the lower supporting member, so as to support the scraping plate and enable the upper surface of the scraping plate to fit with the lower surface of the lower supporting member to facilitate the cutting of waste materials.

The support frame provides support for the support shell, so that the support shell can be spaced apart from the ground so as to collect waste under the support shell; the lifting mechanism is used to connect the support shell and the upper moving member, so that the upper moving member can move vertically, and a lower bearing member is arranged below the upper moving member, and the lower bearing member is arranged on the support shell for carrying the die-cut products, and the vertical movement of the upper moving member drives the waste cleaning member on the lower side to pass through the waste cleaning hole on the lower bearing member, so that the waste at the corresponding position on the product can be pushed downward to the lower side of the lower bearing member to achieve waste cleaning; due to the risk of adhesion between the waste and the product, the upper moving member and the scraping plate are connected by a connecting assembly, and when the upper moving member moves up, the scraping plate is driven to scrape the lower side of the lower bearing member at the same time, so as to cut off the adhesion between the waste and the product and optimize the cleaning effect of the waste; when the upper moving member moves down to clean the waste, the scraping plate is moved to one side of the lower bearing member to avoid the waste cleaning member and avoid collision with the waste cleaning member to affect the reliability of waste cleaning; 2. The lower end of the first waste cleaning needle can be matched with the lower carrier first, and the alignment of the second waste cleaning needle and the waste cleaning hole can be judged in advance. If the detection mechanism detects that the abutment force of the first waste cleaning needle is greater than the preset value, it means that the waste cleaning part has insufficient alignment and needs to be adjusted; if the detection mechanism detects that the abutment force of the first waste cleaning needle is less than the preset value, the alignment of the waste cleaning part is good, and the waste can be cleaned by continuing to move the waste cleaning part downward; because the first waste cleaning needle is arranged on the periphery of the second waste cleaning needle, it can be easily replaced after the first waste cleaning needle collides with the lower carrier and is damaged, reducing the difficulty of disassembly and assembly; 3. When the upper moving part moves downward, the pressing part connected by the elastic part can contact the product before the waste cleaning part, thereby pressing the product to fix the product, so that the waste cleaning part can pass through the through hole to push the waste to the lower side of the waste cleaning hole, thereby optimizing the waste cleaning effect; when the upper moving part moves upward, since the inner circumferential wall of the through hole is provided with a blocking part, the waste cleaning part can push the flexible blocking part to move upward, but since the blocking part reduces the area of ​​the through hole, and the area of ​​the through hole is the same as the area of ​​the waste, the waste can be blocked under the pressing part, thereby reducing the risk of the waste affecting the cleaning effect as the waste cleaning part moves upward.

Moreover, in the description of the present embodiment, the terms "above", "below", "right", etc., the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. Unless otherwise specified, the orientation words used in the present application, such as "inside" and "outside", refer to the contours of the corresponding parts themselves.

[0034] like Figure 1 and Figure 2As shown, an embodiment of the present application discloses a waste removal device for a die-cutting machine (hereinafter referred to as the "device"). The front end of the device is connected to the die-cutting structure through a conveying structure, so that the product with waste after die-cutting by the die-cutting structure can be moved to the device by the conveying structure. The die-cutting structure and the conveying structure can use existing structures, as long as the die-cut products can be transported into the device. The device includes a supporting mechanism 1, a lifting mechanism 2, a waste removal mechanism 3 and a scraping mechanism 4, which are used to remove waste from the product. In this embodiment, the product can be a cardboard, and the waste thereon is a plurality of circular plates, and the circular plates are connected to the cardboard by discontinuous connection points after die-cutting.

[0035] The support mechanism 1 includes a support frame 11 and a support shell 12. The support shell 12 is mounted on the support frame 11. The support frame 11 provides support for the support shell 12 so that the support shell 12 is spaced from the ground so that waste can be collected under the support shell 12. The support shell 12 is provided with an input port, an output port and a waste removal port. The input port and the output port are arranged on two sides of the support shell 12 opposite to each other. The waste removal port is arranged on the bottom surface of the support shell 12 so that waste can fall out of the support shell 12.

[0036] like Figure 1 and Figure 2 As shown, the lifting mechanism 2 is arranged on the lower side of the top surface of the supporting shell 12. The waste cleaning mechanism 3 is connected to the lifting mechanism 2, and the lifting mechanism 2 drives the waste cleaning mechanism 3 to move vertically. The waste cleaning mechanism 3 includes an upper moving member 31, a lower bearing member 32 and a plurality of waste cleaning members. The upper moving member 31 is connected to the lifting mechanism 2 by transmission, so that the lifting mechanism 2 drives the upper moving member 31 to move vertically. A plurality of waste cleaning members are evenly distributed on the lower side of the upper moving member 31, the lower bearing member 32 is arranged on the supporting shell 12, and the lower bearing member 32 is arranged below the upper moving member 31. A plurality of waste cleaning holes 321 are provided on the lower bearing member 32, and the waste cleaning holes 321 are arranged one by one with the waste cleaning members, so that the waste cleaning members can pass through the waste cleaning holes 321 accordingly. The lifting mechanism 2 is used to connect the supporting shell 12 and the upper moving member 31, so that the upper moving member 31 can move vertically. A lower supporting member 32 is arranged below the upper movable member 31. The lower supporting member 32 is arranged on the supporting shell 12 and is used to carry the die-cut product. The vertical movement of the upper movable member 31 drives the waste cleaning member on the lower side to pass through the waste cleaning hole 321 on the lower supporting member 32, so that the waste at the corresponding position on the product can be pushed downward to the lower side of the lower supporting member 32, thereby realizing the waste cleaning operation.

[0037] like Figure 1 and Figure 2As shown, the scraping mechanism 4 includes a connecting assembly and a scraping plate 42, and the connecting assembly is drivingly connected to the upper moving member 31 and the scraping plate 42. The scraping plate 42 is slidably connected to the lower side of the lower bearing member 32, so that the upper surface of the scraping plate 42 and the lower surface of the lower bearing member 32 can contact each other and slide relative to each other. The scraping plate 42 can move to the bottom of the lower bearing member 32 or to one side of the lower bearing member 32, so that when the upper moving member 31 moves up, the scraping plate 42 is driven to move directly below the lower bearing member 32; when the upper moving member 31 moves down, the scraping plate 42 is driven to move to one side of the lower bearing member 32. Since there is a risk of waste materials sticking to products, the upper movable member 31 and the scraping plate 42 are connected by a connecting assembly, so that when the upper movable member 31 moves upward, the scraping plate 42 can be driven to scrape the lower side of the lower supporting member 32 at the same time, so as to cut off the adhesion between the waste materials and the products and optimize the waste cleaning effect; when the upper movable member 31 moves downward to clear the waste, the scraping plate 42 is moved to one side of the lower supporting member 32 to avoid the waste clearing parts and avoid collision with the waste clearing parts to affect the reliability of the waste clearing operation.

[0038] Optionally, a slide groove is provided on the lower side of the lower bearing member 32, and a slider 422 is provided on the upper side of the scraper plate 42, and the slider 422 is slidably connected to the slide groove. The scraper plate 42 can be slidably connected to the lower side of the lower bearing member 32, so as to support the scraper plate 42 and make the upper surface of the scraper plate 42 fit with the lower surface of the lower bearing member 32, so as to cut off the waste and optimize the cleaning effect.

[0039] like Figure 1 and Figure 2 As shown, optionally, the lifting mechanism 2 includes a telescopic member 21, a connecting frame 22 and a sleeve member 23. The telescopic member 21 provides a power source, the fixed end of the telescopic member 21 is connected to the top of the support shell 12, the movable end of the telescopic member 21 is vertically telescopic, and the movable end of the telescopic member 21 is connected to the connecting frame 22. The connecting frame 22 realizes the connection function, and the upper moving member 31 is connected to the connecting frame 22. The outer periphery of the sleeve member 23 is connected to the connecting frame 22, and a support column 121 with a circular cross section is provided in the support shell 12, and the sleeve member 23 is slidably sleeved on the outer periphery of the support column 121. The cooperation of the sleeve member 23 and the support column 121 can optimize the guiding effect, so that the telescopic member 21 drives the upper moving member 31 to realize vertical movement through the connecting frame 22 and the sleeve member 23, reducing the risk of the upper moving member 31 being horizontally deflected and causing the waste removal member and the waste removal hole 321 to be inaccurately aligned, affecting the waste removal effect. The telescopic member 21 can be a structure that can achieve telescopicity, such as a cylinder, a hydraulic cylinder or an electric telescopic rod.

[0040] Optionally, the telescopic member 21 is connected to the center of the connecting frame 22, and a plurality of support columns 121 and sleeve members 23 are provided, and the support columns 121 correspond to the sleeve members 23 one by one, and the sleeve members 23 are evenly distributed in the circumference of the connecting frame 22. The cooperation of multiple sleeve members 23 and multiple support columns 121 can improve the positioning and guiding accuracy. At the same time, the cooperation of multiple sleeve members 23 and multiple support columns 121 also improves the reliability of support, helps to achieve force balance, and enables the upper moving member 31 to move vertically while maintaining horizontality, so that several waste removal members on the lower side of the upper moving member 31 can be accurately inserted into the corresponding waste removal holes 321, avoiding the deflection of the upper moving member 31 in the vertical and horizontal directions and affecting the waste removal effect.

[0041] like Figure 1 and Figure 2 As shown, optionally, the waste stripping part includes a first waste stripping needle 331 and a second waste stripping needle 332, the length of the first waste stripping needle 331 is greater than the length of the second waste stripping needle 332, and the first waste stripping needle 331 is distributed at the peripheral positions of several second waste stripping needles 332. In this embodiment, the first waste stripping needles 331 are distributed at the four corners. The device also includes a detection mechanism, which is arranged between the upper moving member 31 and the first waste stripping needle 331, and the detection mechanism is used to detect the abutment force of the first waste stripping needle 331. By firstly cooperating the lower end of the first waste stripping needle 331 with the longer length with the lower bearing member 32, the alignment of the second waste stripping needle 332 and the waste stripping hole 321 can be judged in advance. If the detection mechanism detects that the abutment force of the first waste cleaning needle 331 is greater than the preset value, it means that the waste cleaning part has insufficient alignment and needs to adjust the product or the waste cleaning part; if the detection mechanism detects that the abutment force of the first waste cleaning needle 331 is less than the preset value, the alignment of the waste cleaning part is good, and the waste can continue to be cleaned by moving the waste cleaning part downward. Since the first waste cleaning needle 331 is arranged on the periphery of the second waste cleaning needle 332, it is easy to replace the first waste cleaning needle 331 after it collides with the lower bearing member 32 and is damaged, thereby reducing the difficulty of disassembly and assembly. The support shell 12 can be provided with a cabinet door so that the first waste cleaning needle 331 can be easily replaced by opening the cabinet door, thereby reducing the difficulty of operation. The waste cleaning part and the upper movable member 31 are detachably connected, including but not limited to connection by screwing, plugging or snapping. The detection mechanism may be a pressure sensor; the device further includes a control mechanism, which is electrically connected to the pressure sensor and the telescopic member 21 and other structures, so that when the pressure sensor detects that the abutment force is greater than a preset value, a signal is sent in time to stop the telescopic member 21 from further extending, thereby reducing the risk of damage to the first waste removal needle 331. It is understandable that the device includes necessary positioning structures to improve the position alignment of the waste removal member, thereby facilitating waste removal.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the waste cleaning mechanism 3 also includes a pressing member 34 and an elastic member 35. One end of the elastic member 35 is connected to the upper movable member 31, and the other end of the elastic member 35 is connected to the pressing member 34, so that the pressing member 34 is arranged below the upper movable member 31. When the upper movable member 31 moves downward, the pressing member 34 connected by the elastic member 35 can contact the product before the waste cleaning member, thereby pressing the product to fix the product, so that the waste cleaning member can pass through the through hole 341 to push the waste to the lower side of the waste cleaning hole 321, thereby optimizing the waste cleaning effect. The pressing member 34 is provided with a plurality of through holes 341, and the through holes 341 correspond to the waste cleaning members one by one. The inner peripheral wall of the through hole 341 is provided with a plurality of blocking portions 342, and the blocking portion 342 extends from the inner peripheral wall of the through hole 341 to the center of the through hole 341, so as to reduce the area of ​​the through hole 341. The blocking portion 342 is used to block the waste from passing through the waste cleaning hole 321 and moving upward. The blocking portion 342 is flexible so that the waste cleaning member can push the blocking portion 342 and pass through the through hole 341. When the upper moving member 31 moves upward, since the inner peripheral wall of the through hole 341 is provided with the blocking portion 342, the waste cleaning member can push the flexible blocking portion 342 upward, but since the blocking portion 342 reduces the area of ​​the through hole 341, and the area of ​​the through hole 341 is the same as the area of ​​the waste, the waste can be blocked under the pressing member 34, reducing the risk of the waste affecting the cleaning effect as the waste cleaning member moves upward.

[0043] In this embodiment, the diameter of the through hole 341 is equal to or slightly larger than the maximum diameter of the waste cleaning member, so that the waste cleaning member can pass through the through hole 341. The blocking portion 342 can be a triangular structure; the blocking portion 342 can be made of a flexible material such as rubber. The waste cleaning member, the through hole 341 and the waste cleaning hole 321 are all arranged correspondingly, so that the waste cleaning member can pass through the through hole 341 and the waste cleaning hole 321, and push the waste on the lower bearing member 32 to the bottom of the lower bearing member 32. The upper moving member 31, the lower bearing member 32 and the pressing member 34 can all be plate-like structures; the elastic member 35 can be a spring.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the connecting assembly includes a first rack 411, a first gear 412, a connecting shaft 413 and a second gear 414. The first rack 411 is connected to the upper moving member 31, the first rack 411 extends vertically, the first gear 412 meshes with the first rack 411, and the connecting shaft 413 connects the first gear 412 and the second gear 414. The second gear 414 is arranged below the scraping plate 42, and a second rack 421 is arranged on the lower side of the scraping plate 42, and the second rack 421 meshes with the second gear 414, so that the vertical movement of the upper moving member 31 drives the scraping plate 42 to move horizontally. During the waste cleaning operation, the vertical movement of the upper moving member 31 drives the first rack 411 to move vertically, thereby rotating the first gear 412, and driving the second gear 414 to rotate through the connection of the connecting shaft 413, and the second rack 421 meshes with the second gear 414, thereby causing the second rack 421 to move horizontally, so that the scraping plate 42 can move horizontally under the lower bearing member 32, so as to cut off the waste materials that are adhered to the product and optimize the waste cleaning effect. A guide groove can be set in the support shell 12, so that the first rack 411 can be slidably set in the guide groove to ensure that the first rack 411 moves in the vertical direction. A clearance opening is set on the bottom surface of the support shell 12, and the clearance opening corresponds to the first rack 411, so that the first rack 411 can pass through the clearance opening to avoid interference between the first rack 411 and the support shell 12.

[0045] Optionally, the connection assembly further includes an extension piece 415. The extension piece 415 extends in a width direction perpendicular to the conveying direction in a horizontal plane, and the upper end of the first rack 411 is connected to the extension piece 415, so that the first rack 411 is arranged on one side of the upper moving member 31. The extension piece 415 enables both the first rack 411 and the first gear 412 to be arranged on one side of the upper moving member 31 and the lower bearing member 32, thereby reducing the risk of interference.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the connecting shaft 413 is rotatably connected to the supporting housing 12 through the supporting seat, and the first gear 412 and the second gear 414 are horizontally spaced and connected to the connecting shaft 413. The connecting shaft 413 can rotate relative to the supporting housing 12, so that the rotation of the first gear 412 can drive the connecting shaft 413 to rotate, and then drive the second gear 414 to rotate, so as to realize the transmission from the first rack 411 to the second rack 421. In addition, through the connection of the connecting shaft 413, the second gear 414 can be arranged below the second rack 421 to achieve meshing.

[0047] like Figure 1 , Figure 2 and Figure 3As shown, optionally, two scraping mechanisms 4 are provided, and the two scraping mechanisms 4 are symmetrically arranged on both sides of the axis of the lower supporting member 32 perpendicular to the conveying direction, and the two first racks 411 are arranged opposite to each other. The two symmetrically arranged scraping mechanisms 4 can reduce the length of the scraping plate 42 along the conveying direction, avoid the problem that the scraping plate 42 extends too long horizontally when the scraping plate 42 moves to one side of the lower supporting member 32 and affects the reliability, and can also reduce the risk of interference with other structures. The rack surfaces of the two first racks 411 are arranged opposite to each other, which can make the two scraping plates 42 relatively far apart when the upper moving member 31 moves downward; and make the two scraping plates 42 relatively close to each other when the upper moving member 31 moves upward, so as to avoid the scraping plates 42 from interfering with the waste cleaning parts.

[0048] It can be understood that the device also includes necessary structures for functions such as connection, support, driving, limiting, positioning and control so that the device can operate normally; parameters such as the shape, size, material and setting quantity of each part of the device can be determined as needed as long as the corresponding functions can be achieved.

[0049] The implementation principle of a waste cleaning device for a die-cutting machine in the embodiment of the present application is as follows: the lower supporting member 32 carries the die-cut product, and the vertical movement of the upper moving member 31 drives the waste cleaning member on the lower side to pass through the waste cleaning hole 321 on the lower supporting member 32, so that the waste at the corresponding position on the product can be pushed downward to the lower side of the lower supporting member 32 to achieve waste cleaning; when the upper moving member 31 moves downward to clean the waste, the scraping plate 42 is moved to one side of the lower supporting member 32 to avoid the waste cleaning member and avoid collision with the waste cleaning member to affect the reliability of waste cleaning; since there is a risk of waste sticking to the product, when the upper moving member 31 moves upward, it also drives the scraping plate 42 to scrape the lower side of the lower supporting member 32, thereby cutting off the adhesion between the waste and the product and optimizing the waste cleaning effect.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
