Description

Technical Field

[0001] This invention relates to die-cutting equipment, and more particularly to a waste removal mechanism for a die-cutting machine. Background Technology

[0002] Chinese utility patent with publication number CN205148449U discloses a waste removal die-cutting machine. When the waste removal needle rotates with the waste removal roller to the waste removal comb, the waste removal needle passes through the comb opening on the waste removal comb, while the waste material is stuck on the waste removal comb and then falls off. When the movement is unstable, the waste removal needle will collide with the waste removal comb, which poses a risk of needle breakage. Summary of the Invention

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a waste removal mechanism for a die-cutting machine, which is equipped with a cam lifting waste removal component to separate waste material from the waste removal needle, actively remove waste, and eliminate the risk of needle breakage.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the waste removal mechanism of the die-cutting machine includes a cooperating roller and a waste removal roller that cooperate with each other. The waste removal roller is provided with a waste removal needle. The waste removal roller is rotatably arranged. The waste removal needle is equipped with a waste removal component. The waste removal component is arranged to move radially along the waste removal roller. The waste removal component is equipped with a cam. The cam is arranged inside the waste removal roller. The cam has a lifting section.

[0005] In this scheme, after the waste removal needle pushes out the waste material, the cam lifting section lifts the waste removal part to separate the waste removal needle from the waste material.

[0006] Preferably, the mating roller is a rubber roller, and the rubber layer of the mating roller has pinholes for the waste removal needle and the waste removal part to pass through, and the cam is fixedly set.

[0007] In this scheme, the waste removal needles on the waste removal roller form pinholes on the rubber roller, eliminating the need for pre-drilling and alignment. The cam is fixedly set, eliminating the need for differential rotation design, resulting in a simple structure.

[0008] Preferably, the waste removal needles are arranged along the axial direction of the waste removal roller.

[0009] In this scheme, the waste removal needles are arranged along the axial direction to remove waste from multiple groups of materials continuously.

[0010] Preferably, the scrapped part is fitted over the waste removal needle.

[0011] In this scheme, the scrap part is set outside the scrap removal needle, and the scrap part is fully lifted along the circumference of the scrap removal needle, so that the scrap part is reliably separated from the scrap removal needle.

[0012] Preferably, the scrap removal part is provided with an mounting sleeve, the mounting sleeve is threadedly connected to the waste cleaning roller, a connecting shaft is provided between the mounting sleeve and the waste cleaning needle, and the scrap removal part is provided with an elongated hole for the connecting shaft to pass through and move.

[0013] In this design, the connecting shaft provides support for the waste removal needle, and the movement of the connecting shaft along the elongated hole allows the scrap part to move relative to the waste removal needle.

[0014] Preferably, the waste removal roller has a feeding assembly on its feeding side and a discharge assembly arranged along the axial direction of the waste removal roller on its discharge side. A paper guide strip connects the feeding assembly and the discharge assembly, and the paper guide strip corresponds one-to-one with the discharge assembly.

[0015] In this solution, the discharge assembly and guide strip can support the finished part of the material, while the waste part falls off due to lack of support.

[0016] Preferably, the cooperating roller is positioned above the waste removal roller, the cooperating roller is vertically adjustable, and a waste collection bin is provided below the waste removal roller.

[0017] In this scheme, the waste collection bin collects the fallen waste materials.

[0018] Preferably, the discharge assembly includes an upper conveyor belt and a lower conveyor belt. The upper conveyor belt is wound around an upper roller assembly, and the lower conveyor belt is wound around a lower roller assembly. The paper guide strip has a notch for the lower conveyor belt to pass through. The upper conveyor belt has an inclined section, and the inclined section, together with the paper guide strip and the lower conveyor belt, forms a gradually narrowing inlet.

[0019] In this scheme, the upper and lower conveyor belts work together to transport finished materials. The feed inlet ensures that the finished materials first come into contact with the lower conveyor belt, and then the upper conveyor belt comes into contact with the finished materials, resulting in smooth feeding.

[0020] Preferably, the feeding assembly includes a guide plate, which is fastened to a mounting plate, and a gap is provided between the guide plate and the mounting plate for the guide strip to pass through.

[0021] In this design, the guide plate and the mounting plate clamp the guide strip, providing reliable support for the guide strip.

[0022] Preferably, a set of slide rails is provided below the waste removal roller, the slide rails extend along the axial direction of the waste removal roller, a slider is slidably arranged on the slide rails, the slider has an inclined inward supporting surface, the waste removal roller is rotatably arranged between the two machine frames, one of the machine frames is provided with a through hole for the slide rails and the waste removal roller to pass through, and a supporting wheel is provided at the through hole.

[0023] In this scheme, when disassembling the waste cleaning roller, the waste cleaning roller is supported by a slider, and the waste cleaning roller is pulled out along the slide rail through the through hole. The waste cleaning roller can be moved away by means of crane or other means.

[0024] The beneficial effects of this invention are as follows: after the waste removal needle ejects the waste material, the cam lifting section lifts the waste removal component, separating the waste removal needle from the waste portion of the material, thus actively removing waste and eliminating the risk of needle breakage; the discharge assembly and guide strip can support the finished product portion of the material, while the waste portion falls off due to lack of support. Therefore, this invention has substantial features and progress compared with the prior art. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the implementation of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0038] See appendix Figure 1-6 In one embodiment of this invention, a waste removal mechanism for a die-cutting machine includes a cooperating roller 1 and a waste removal roller 2 that cooperate with each other. The waste removal roller 2 is provided with waste removal needles 3 and is rotatably arranged.

[0039] The waste removal needle 3 is equipped with a waste removal component 4, which is radially movable along the waste removal roller 2. The waste removal component 4 is sleeved on the waste removal needle 3, and an mounting sleeve 8 is sleeved on the waste removal component 4. The mounting sleeve 8 is threadedly connected to the waste removal roller 2. A connecting shaft is provided between the mounting sleeve 8 and the waste removal needle 3. The waste removal component 4 has an elongated hole 21 for the connecting shaft to pass through and move. The waste removal component 4 is equipped with a cam, which is fixedly installed inside the waste removal roller 2. The cam has a lifting section. The waste removal needle 3 is arranged axially along the waste removal roller 2. The cooperating roller 1 is a rubber roller, and the rubber layer of the cooperating roller 1 has needle holes for the waste removal needle 3 and the waste removal component 4 to pass through.

[0040] In this embodiment, the waste removal roller 2, in conjunction with the cooperating roller 1, drives the material to be conveyed backward. The waste removal roller 2 drives the waste removal needle 3 to rotate into position. During the conveying process, the waste removal needle 3 comes into contact with the waste portion of the material, causing it to be subjected to force and separated from the finished product portion. Then, the cam lifting section lifts the waste removal component 4 to separate the waste removal needle 3 from the waste portion. The cooperating roller 1 is either rotatable or fixed. The rotating shaft of the waste removal roller 2 is sleeved on the central shaft for cam mounting. A rolling bearing can be installed between the two. The rotating shaft is connected to the power source via gear transmission. The rotating shaft and the roller body of the waste removal roller 2 are connected. The connection via keyway is not limited to this; the outer contour design of the cam is a mature technology, and the lifting section achieves lifting by abutting against the scrap removal part 4; the scrap removal part 4 can also be adjacent to the scrap cleaning needle 3, and the scrap part can be separated from the scrap cleaning needle 3 when the lifting height is sufficient; the scrap cleaning roller 2 can be an aluminum roller or a steel roller, and the mating roller 1 can also be an aluminum roller or a steel roller. The needle holes on the mating roller 1 are pre-drilled and matched with the scrap cleaning needle 3 on the scrap cleaning roller 2; when the scrap cleaning roller 2 is located above the mating roller 1, an elastic element is also required to keep the scrap removal part 4 in a retracted state.

[0041] In other alternative embodiments, the cam can be rotatably set. Assuming that there are N sets of waste removal needles 3 on the waste removal roller 2, each set of waste removal needles 3 corresponds to a set of materials to be waste removed, the rotation speed of the cam is N times the rotation speed of the waste removal roller 2, so that when each set of waste removal needles 3 rotates to the position, the lifting section of the cam also rotates to the position to lift the waste removal part 4.

[0042] See appendix Figure 1-3 The waste removal roller 2 has a feeding assembly 5 on its feeding side and a discharge assembly 6 arranged axially along its discharge side. A guide strip 7 connects the feeding assembly 5 and the discharge assembly 6, with each guide strip 7 corresponding to one of the discharge assemblies 6. A cooperating roller 1 is positioned above the waste removal roller 2 and is vertically adjustable. A waste collection bin 9 is located below the waste removal roller 2. The discharge assembly 6 includes an upper conveyor belt 10 and a lower conveyor belt 11. The upper conveyor belt 10 is wound around the upper roller assembly 12, and the lower conveyor belt 11 is wound around the lower roller assembly 13. The paper guide strip 7 has a notch 14 for the lower conveyor belt 11 to pass through. The upper conveyor belt 10 has an inclined section 16, which, together with the paper guide strip 7 and the lower conveyor belt 11, forms a gradually narrowing feed inlet 15. The feed assembly 5 includes a guide plate 17, which is fastened to the mounting plate. A gap is provided between the guide plate 17 and the mounting plate for the paper guide strip 7 to pass through.

[0043] In this embodiment, the feeding component 5 conveys material to the waste removal roller 2. The material is received by the discharge component 6 along the guide plate 17 and the guide strip 7. When passing through the waste removal roller 2, the waste removal needle 3 separates the waste part from the finished part. The waste removal part 4 separates the waste part from the waste removal needle 3. The waste part falls into the waste collection bin 9 due to lack of support. The finished part first contacts the lower conveyor belt 11 and then contacts the upper conveyor belt 10, and the conveying is smooth. Among them, strip-shaped holes can be set on the guide strip 7 for the waste removal needle 3 to pass through and for the waste part to fall. The guide strip 7 can support the edge of the finished part to prevent the edge of the finished part from collapsing due to gravity. Alternatively, the waste part can be designed to fall between the guide strips 7.

[0044] See appendix Figure 7-8 Below the waste removal roller 2, there is a set of slide rails 18. The slide rails 18 extend along the axial direction of the waste removal roller 2. A slider 19 is slidably arranged on the slide rails 18. The slider 19 has an inclined inward supporting surface. The waste removal roller 2 is rotatably arranged between the two side frames 22. One side of the frame 22 is provided with a through hole for the slide rails 18 and the waste removal roller 2 to pass through. A supporting wheel 20 is provided at the through hole.

[0045] In this embodiment, the support roller 20 reduces the frictional force on the push-pull waste removal roller 2. The waste removal roller 2 is supported by the slider 19 and moves along the slide rail 18 with the slider 19. There is enough space to transfer the waste removal roller 2 by means of a crane or other means. When placing the waste removal roller 2, the slider 19 and the waste removal roller 2 can be offset axially. The frame 22 on one side is provided with an opening and closing door 23 for installing the waste removal roller 2. When installing the waste removal roller 2, it can be lifted for installation, which is a mature technology. Alternatively, the slider 19, the support roller 20 and the waste removal roller 2 can be made to make point contact to reduce the frictional force, so that the slider 19 and the support roller 20 will not affect the rotation of the waste removal roller 2. A stop block can be set to indicate that the waste removal roller 2 has been pushed into place. Sliders 19 are set on both sides of the support roller 20 to relay the force, so that the slider 19 does not need to cross the support roller 20.

[0046] The above description represents the preferred embodiments of the present invention. It should be noted that the scope of protection of the present invention is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in the present invention, and these can also be considered within the scope of protection of the present invention.
