Description

Technical Field

[0001] The utility model relates to the field of die cutting machines, in particular to a die cutting waste removal device and a die cutting machine. Background Art

[0002] In some existing die-cutting machines, the cutting mechanism performs pattern cutting on the film. After cutting, the waste sheet and the main body of the film have several point connections, so that the waste sheet and the main body of the film can be transported together to the die-cutting waste removal device, and the die-cutting waste removal device then removes the waste sheet from the main body of the film. An existing die-cutting waste removal device includes a waste removal wheel and a hook arranged on the waste removal wheel, and the waste removal wheel is located on one side of the film. When the waste removal wheel rotates, the hook first approaches and penetrates into the waste sheet to a certain depth. As the waste removal wheel rotates, the hook begins to move away from the main body of the film and drives the waste sheet to separate from the main body of the film. However, the hook and the waste sheet are basically in point contact, and the friction between the two is insufficient. In the process of some hooks gradually moving away from the main body of the film, it is possible that the hook has already separated from the waste sheet before the waste sheet separates from the main body of the film, making it impossible to remove some waste sheets, resulting in the process of removing the waste sheet from the film being not stable enough, affecting the quality stability of the product.

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 invention.

[0034] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] In some existing die-cutting machines, the cutting mechanism 600 performs pattern cutting on the film. After cutting, the waste sheet is connected to the main body of the film at several points, so that the waste sheet and the main body of the film can be transported together to the die-cutting waste removal device, and the die-cutting waste removal device then removes the waste sheet from the main body of the film. An existing die-cutting waste removal device includes a waste removal wheel and a hook disposed on the waste removal wheel, and the waste removal wheel is located on one side of the film. When the waste removal wheel rotates, the hook first approaches and penetrates into the waste sheet to a certain depth. As the waste removal wheel rotates, the hook begins to move away from the main body of the film and drives the waste sheet to separate from the main body of the film. However, the hook hook and the waste sheet are basically in point contact, and the friction between the two is insufficient. In the process of part of the hook hook gradually moving away from the diaphragm body, it is possible that the hook hook has already detached from the waste sheet before the waste sheet detaches from the diaphragm body, making it impossible to remove part of the waste sheet, resulting in an unstable process for removing the waste sheet from the diaphragm, affecting the quality stability of the product; and in the mold cutting and waste removal device with this structure, after the hook hook separates the waste sheet from the diaphragm body, an additional separation device is still required to separate the waste sheet from the hook hook, and the structure is relatively complicated.

[0037] Reference Figures 1 to 4 , is a mold removal waste device of an embodiment of the utility model, comprising a base body 100 and a clamping waste removal mechanism 200. The clamping waste removal mechanism 200 is arranged on the base body 100, and the clamping waste removal mechanism 200 comprises a first waste removal wheel 210, a second waste removal wheel 220, a rotation driver 230 and a clamping driver 240. The first waste removal wheel 210 and the second waste removal wheel 220 are opposite to each other, and the second waste removal wheel 220 is movably arranged on the base body 100 and can approach or move away from the first waste removal wheel 210. The first waste removal wheel 210 and the second waste removal wheel 220 are rotatably arranged, and the rotation axis of the first waste removal wheel 210 and the rotation axis of the second waste removal wheel 220 are arranged parallel and spaced apart. The rotation driver 230 is used to drive the first waste removal wheel 210 to rotate, and the clamping driver 240 is used to drive the first waste removal wheel 210 and the second waste removal wheel 220 to approach or move away from each other, and a diaphragm passing position is formed between the first waste removal wheel 210 and the second waste removal wheel 220.

[0038] The cut diaphragm passes through the die-cutting waste removal device. When the waste piece to be removed enters the diaphragm passing position, the rotating driver 230 can drive the first waste removal wheel 210 to rotate, and the clamping driver 240 can drive the first waste removal wheel 210 and the second waste removal wheel 220 to approach each other to clamp the waste piece between them, so that the waste piece and the first waste removal wheel 210 and the second waste removal wheel 220 generate a large friction force, and the friction force drives the waste piece to separate from the diaphragm; the first waste removal wheel 210 and the second waste removal wheel 220 are in line contact with the waste piece, so that the friction force between the first waste removal wheel 210 and the second waste removal wheel 220 and the waste piece is large, so that the waste piece can be removed from the diaphragm relatively stably, thereby improving the quality stability of the product; and the first waste removal wheel 210 and the second waste removal wheel 220 do not need to be separated from the waste piece in other mechanisms, so that the above structure is relatively simple.

[0039] In the embodiment, a bearing wheel 300 is further included, and the clamping and waste removal mechanism 200 further includes a transmission shaft 250, which is rotatably connected to the base body 100, the first waste removal wheel 210 is connected to the transmission shaft 250 and rotates synchronously with the transmission shaft 250, the second waste removal wheel 220 is located above the first waste removal wheel 210, the rotation driver 230 is used to drive the transmission shaft 250 to rotate, the bearing wheel 300 is rotatably connected to the transmission shaft 250, and the rotation axis is coaxially arranged with the transmission shaft 250. When the diaphragm passes through the mold removal and waste removal device, the bearing wheel 300 can support and guide the diaphragm, so that the diaphragm is relatively straightened and tensioned. Since the bearing wheel 300 is rotatably arranged on the transmission shaft 250, when the diaphragm moves at the first speed, the peripheral line speed of the first waste removal wheel 210 can rotate at the second speed, and the friction drives the waste sheet to move relative to the diaphragm body, so that the waste sheet is separated from the diaphragm body. The bearing wheel 300 can keep the diaphragm body in a stable state, and the peripheral line speed of the bearing wheel 300 is different from that of the first waste removal wheel 210. It can be understood that the first speed can be equal to zero, that is, the diaphragm body is in a stationary state, or it can be greater than zero, that is, during the normal movement of the diaphragm, the first waste removal wheel 210 runs at the second speed of the peripheral line speed to peel off the waste sheet, and the first speed and the second speed are different at this time. Usually the second speed is greater than the first speed, which is convenient for the discharge of the waste sheet.

[0040] Specifically, in some embodiments, after the film is stationary, the waste sheet stays between the first waste removal wheel 210 and the second waste removal wheel 220. At this time, the clamping driver 240 drives the second waste removal wheel 220 to approach the first waste removal wheel 210 to clamp the waste sheet, and the rotation driver 230 drives the first waste removal wheel 210 to rotate, so as to peel the waste sheet off the main body of the film and discharge it; during this period, the bearing wheel 300 is stationary relative to the base body 100, and the main body of the film also remains stationary. After peeling off the waste sheet, the second waste removal wheel 220 is reset, and there is basically no friction between the film and the first waste removal wheel 210, and the film can move normally.

[0041] Specifically, in other embodiments, when the diaphragm moves, the rotation driver 230 may also drive the first waste removal wheel 210 to move the diaphragm by friction at the same first speed. When the waste sheet enters between the first waste removal wheel 210 and the second waste removal wheel 220, the clamping driver 240 drives the second waste removal wheel 220 and the first waste removal wheel 210 to clamp the waste sheet, and the rotation driver 230 drives the first waste removal wheel 210 to rotate at the second speed for a short time, and friction drives the waste sheet to move relative to the diaphragm body, thereby peeling the waste sheet off the diaphragm body, and finally discharging the waste sheet.

[0042] Specifically, the rotation driver 230 is a speed-adjustable reduction motor. It is conceivable that the rotation driver 230 can also be other structures that output rotational power, such as a common motor or an internal combustion engine, etc. Those skilled in the art can configure it specifically according to actual needs.

[0043] It can be understood that the rotation driver 230 can drive the first waste removal wheel 210 to rotate alone, or can drive the second waste removal wheel 220 to rotate alone, or can synchronously drive the first waste removal wheel 210 and the second waste removal wheel 220 to rotate through a belt drive structure, a gear drive structure, etc., and both can peel off waste sheets through friction.

[0044] It is understandable that, in some embodiments, the first waste removal wheel 210 and the load-bearing wheel 300 may also be arranged on different axes.

[0045] Specifically, the outer diameters of the first waste removal wheel 210 and the second waste removal wheel 220 can be of the same specification, thereby simplifying the material types of the mold removal waste removal device; it is understandable that the outer diameters of the first waste removal wheel 210 and the second waste removal wheel 220 can also be different, and technicians in this field can make specific configurations according to actual needs.

[0046] Specifically, the outer diameters of the first waste removal wheel 210 and the load-bearing wheel 300 are of the same specification.

[0047] In the embodiment, four first waste removal wheels 210 are provided, and five bearing wheels 300 are provided, and the first waste removal wheels 210 and the bearing wheels 300 are alternately arranged along the central axis direction of the transmission shaft 250. The first waste removal wheels 210 and the bearing wheels 300 are alternately arranged, which can reduce the impact on the membrane body between the two waste sheets when the first waste removal wheel 210 and the second waste removal wheel 220 clamp and peel the waste sheet, so that the membrane body can better maintain structural stability.

[0048] It is conceivable that the number of the first waste removal wheel 210 and the load-bearing wheel 300 can also be other numbers, for example, two or more first waste removal wheels 210 are provided, and two or more load-bearing wheels 300 are provided, and those skilled in the art can make specific configurations according to actual needs. The first waste removal wheel 210 and the load-bearing wheel 300 can also be arranged in other ways, which are not limited here.

[0049] In an embodiment, the position of the first waste removal wheel 210 can be adjusted along the axial direction of the transmission shaft 250, and the position of the second waste removal wheel 220 can be adjusted along the rotation axis direction of the second waste removal wheel 220, so as to adapt to the position of waste sheets that need to be removed in membrane products of different specifications, thereby improving the versatility of the equipment.

[0050] Specifically, the first waste removal wheel 210 is key-connected and sleeved on the outer periphery of the transmission shaft 250, and the position of the first waste removal wheel 210 can be adjusted along the transmission shaft 250 by applying a large force. It is conceivable that the first waste removal wheel 210 can also be screwed to the outer periphery of the transmission shaft 250, and the outer periphery of the transmission shaft 250 can be arranged with a plurality of threaded holes along the central axis direction, and screws are threadedly connected to different threaded holes, so as to adjust the position of the first waste removal wheel 210 relative to the transmission shaft 250.

[0051] Specifically, the second waste removal wheel 220 is arranged on the clamping driver 240, the base body 100 is provided with a clearance slot along the rotation axis direction of the second waste removal wheel 220, and the base body 100 is provided with a handle bolt, which is passed through the clearance slot and threadedly connected to the clamping driver 240 to lock the clamping driver 240 and the second waste removal wheel 220 to the base body 100. When the handle bolt is loosened, the position of the clamping driver 240 and the second waste removal wheel 220 can be adjusted along the clearance slot. It is conceivable that the second waste removal wheel 220 can also be rotatably connected to the connecting seat, and the connecting seat is slidably connected to the base body 100 through a slide rail slider structure along the rotation axis direction of the second waste removal wheel 220, and the connecting seat is provided with a threaded hole, and a screw is threadedly connected to the threaded hole. When the screw is tightened, it can press against the base body 100 to limit the position of the second waste removal wheel 220 relative to the base body 100; when the screw is loosened, the position of the second waste removal wheel 220 relative to the base body 100 can be adjusted; or a lead screw is provided on the base body 100, and a lead screw nut is provided on the clamping driver 240, and the lead screw and the lead screw nut are threadedly matched, and the position of the clamping driver 240 and the second waste removal wheel 220 is adjusted by rotating the lead screw.

[0052] In the embodiment, the clamping driver 240 includes a fixed part and an action part, the action part is movably arranged on the fixed part in a direction toward or away from the first waste removal wheel 210, and the second waste removal wheel 220 is rotatably connected to the action part. The above structure drives the second waste removal wheel 220 to approach or move away from the first waste removal wheel 210 through the movable part, so that the first waste removal wheel 210 and the second waste removal wheel 220 are moved closer to or away from each other, and the structure is simple and easy to implement.

[0053] Specifically, the clamping driver 240 is a cylinder, the fixed part is a cylinder seat, and the action part is a cylinder rod. The second waste removal wheel 220 is directly rotatably connected to the cylinder rod of the cylinder. It is conceivable that the second waste removal wheel 220 can also be rotatably connected to a connecting frame, and the connecting frame is slidably connected to the base body 100 through a slide rail slider structure, and the connecting frame and the second waste removal wheel 220 are driven by the clamping driver 240 to move close to or away from the first waste removal wheel 210.

[0054] It is conceivable that the clamping driver 240 can also be other structures, such as a structure that outputs linear power, such as an electric cylinder or an oil cylinder, or the clamping driver 240 includes a servo motor and a connecting frame, one end of the connecting frame is connected to the servo motor, and the other end of the connecting frame is pivotally connected to the second waste removal wheel 220. The servo motor can drive the connecting frame to rotate, and rotate the second waste removal wheel 220 closer to or away from the first waste removal wheel 210.

[0055] It is conceivable that the clamping drive 240 can also be a cylinder and connecting rod structure, and the first waste removal wheel 210 and the second waste removal wheel 220 are both slidably connected to the base body 100, and the first waste removal wheel 210 and the second waste removal wheel 220 can be driven to move closer or farther synchronously through the cylinder and connecting rod structure; or the clamping drive 240 can independently drive the first waste removal wheel 210 to move closer to the second waste removal wheel 220.

[0056] In the embodiment, four first waste removal wheels 210 and four second waste removal wheels 220 are provided, and the first waste removal wheels 210 and the second waste removal wheels 220 are opposite to each other. There are several waste pieces on the membrane, and four first waste removal wheels 210 and four second waste removal wheels 220 are provided, so that waste pieces at different positions can be removed conveniently.

[0057] In the embodiment, four clamping drivers 240 are provided and are connected to the second waste removal wheels 220 in a one-to-one correspondence, so as to facilitate the removal of waste pieces at designated positions separately, and the use effect is better.

[0058] It is conceivable that two or more second waste removal wheels 220 can be provided, and those skilled in the art can make specific configurations according to actual needs. Usually, the number of first waste removal wheels 210 and second waste removal wheels 220 is the same; two or more clamping drives 240 can also be provided, and usually, the number of second waste removal wheels 220 and clamping drives 240 is the same.

[0059] Specifically, the load-bearing wheel 300 can be rotatably connected to the transmission shaft 250 via a bearing. It is understandable that the load-bearing wheel 300 can also directly use a bearing; or the load-bearing wheel 300 can be rotatably sleeved on the transmission shaft 250 in a sliding fit manner.

[0060] Specifically, the first waste removal wheel 210 and the second waste removal wheel 220 can have a relatively rough surface, such as a wheel body made of polyurethane, to increase the friction of the first waste removal wheel 210 and the second waste removal wheel 220 on the waste sheet. The load-bearing wheel 300 can have a relatively smooth surface to reduce the friction on the membrane.

[0061] Reference Figure 3 The utility model also discloses a die-cutting machine, including a machine base 400, a detection camera 500, a cutting mechanism 600 and the above-mentioned die-cutting waste removal device. The detection camera 500 is arranged on the machine base 400; the cutting mechanism 600 is arranged on the machine base 400; the die-cutting waste removal device is arranged on the machine base 400, and the detection camera 500, the cutting mechanism 600 and the die-cutting waste removal device are arranged in sequence along the conveying direction of the film. Due to the adoption of the above-mentioned die-cutting waste removal device, the stability of the products produced by the die-cutting machine can be improved; the detection camera 500 is set to align and correct the position of the passing film, thereby improving the accuracy of the die-cutting position.

[0062] Specifically, the position of the cutting mechanism 600 relative to the machine base 400 can be adjusted to facilitate the alignment and deviation correction of the die-cutting position.

[0063] Specifically, the film may first pass through the detection camera 500 and then pass through the cutting mechanism 600, that is, the detection camera 500 is located on the same side of the cutting mechanism 600 and the mold cutting waste removal device. Alternatively, the film may first pass through the cutting mechanism 600 and then pass through the detection camera 500, that is, the detection camera 500 may be located between the mold cutting waste removal device and the cutting mechanism 600. Those skilled in the art may make specific configurations according to actual needs.

[0064] Specifically, there are many cutting mechanisms 600 for die-cutting machines on the market, which are not limited here, and those skilled in the art can configure them specifically according to actual needs.

[0065] In the embodiment, two film tensioning and conveying mechanisms 700 are further included. The film tensioning and conveying mechanisms 700 are disposed on the machine base 400. The two film tensioning and conveying mechanisms 700 are located on opposite sides of the cutting mechanism 600 to facilitate tensioning and conveying of the film.

[0066] Specifically, the film tensioning and conveying mechanism 700 can be position-adjustable, so as to facilitate the alignment and deviation correction of the die-cutting position. The film tensioning and conveying mechanism 700 includes two clamping rollers and a clamping roller driver, and the clamping roller driver drives the clamping rollers to rotate, clamp and convey the film.

[0067] Furthermore, in some embodiments, a film storage adjustment mechanism 800 is further included. The film storage adjustment mechanism 800 is located between the two film tensioning and conveying mechanisms 700. The film storage adjustment mechanism 800 can adjust the film length between the two film tensioning and conveying mechanisms 700. Since the conveying speeds of the two film tensioning and conveying mechanisms 700 may not be synchronized enough, the film between the two may be torn, cracked or deformed. Therefore, the film storage adjustment mechanism 800 is provided to adjust the film length between the two film tensioning and conveying mechanisms 700, thereby reducing the risk of the film between the two film tensioning and conveying mechanisms 700 being torn, cracked or deformed.

[0068] Specifically, two diaphragm tensioning and conveying mechanisms 700 are arranged on a first plane and arranged at intervals, and the film storage regulating mechanism 800 is arranged on one side of the first plane. The film storage regulating mechanism 800 includes an regulating frame 810 and an regulating driver 820. The regulating driver 820 can drive the regulating frame 810 to approach or move away from the first plane. The regulating frame 810 is provided with a rotating roller, and the diaphragm between the two diaphragm tensioning and conveying mechanisms 700 bypasses the rotating roller. When the length of the diaphragm between the two diaphragm tensioning and conveying mechanisms 700 is shortened, the regulating frame 810 drives the rotating roller to approach the first plane to keep the diaphragm tensioned; when the length of the diaphragm between the two diaphragm tensioning and conveying mechanisms 700 is lengthened, the regulating frame 810 drives the rotating roller away from the first plane to keep the diaphragm tensioned. The regulating driver 820 can be a cylinder or a spring, etc., so that the diaphragm is automatically kept tensioned.

[0069] Specifically, a rotating roller is also provided on the first plane, so that the film sheet in the area outside the film storage adjustment mechanism 800 is kept on the first plane for transportation.

[0070] In the embodiment, the seat body 100 includes a lower frame 110 and an upper frame 120, a first waste removal wheel 210 is arranged on the lower frame 110, a second waste removal wheel 220 is arranged on the upper frame 120, and the upper frame 120 is rotatably arranged on the lower frame 110 and can rotate relative to the lower frame 110 in a direction away from the cutting mechanism 600. When the upper frame 120 rotates away from the cutting mechanism 600, it can give way to the cutting mechanism 600 for maintenance work such as replacing the cutting blade, and the equipment does not need to disassemble the die cutting and waste removal device as a whole to perform maintenance on the cutting mechanism 600. Specifically, the upper frame 120 is vertically provided with a rotating shaft, and the lower frame 110 is provided with a rotating shaft hole, and the rotating shaft is penetrated through the rotating shaft hole, so that the two are rotatably connected, and a thrust ball bearing is provided between the upper frame 120 and the lower frame 110 to support the position of the upper frame 120.

[0071] In the embodiment, the base 100 further includes a locking mechanism 130, which can lock or unlock the position of the upper frame 120 relative to the lower frame 110. The locking mechanism 130 is provided, and when the locking mechanism 130 locks the positions of the upper frame 120 and the lower frame 110, the upper frame 120 is prevented from accidentally rotating relative to the lower frame 110, thereby affecting the operation of the first waste removal wheel 210 and the second waste removal wheel 220; when the locking mechanism 130 unlocks the positions of the upper frame 120 and the lower frame 110, the upper frame 120 can be allowed to rotate away from the cutting mechanism 600.

[0072] Specifically, the locking mechanism 130 is a quick clamp, which is relatively easy to purchase and use. It is conceivable that the locking mechanism 130 can also use screws, and a through hole is set in the upper frame 120, and a threaded hole is set in the lower frame 110. When the screw is inserted into the through hole and threadedly connected to the threaded hole, the position of the upper frame 120 relative to the lower frame 110 can be locked, and when the screw is loosened, the upper frame 120 can be rotated relative to the lower frame 110; or the locking mechanism 130 uses a latch, and a latch hole is set in the upper frame 120 and the lower frame 110. When the latch is inserted into the latch hole, the position of the upper frame 120 relative to the lower frame 110 can be locked, and when the latch is pulled out, the upper frame 120 can be rotated relative to the lower frame 110.
