[0036] The utility model provides a punching waste discharge device for pearl cotton production. Figures 1 to 3 The utility model provides an embodiment of a punching waste discharge device for pearl cotton production.

[0037] Please also read Figures 1 to 3The punching waste discharge device for pearl cotton production includes a workbench 1, a punching device 2, an ejector assembly 3 and a cleaning assembly 4. The workbench 1 is used to place a workpiece, the punching device 2 is arranged on the workbench 1, the punching device 2 is used to punch holes, the ejector assembly 3 is arranged on the punching device 2, and the ejector assembly 3 moves toward or away from the blade of the punching device 2 tool to push out the waste stuck in the punching device 2 tool. The cleaning assembly 4 is arranged on the outside of the punching device 2 tool. The cleaning assembly 4 is telescopically arranged to clean the debris on the punching device 2 tool when the cleaning assembly 4 shrinks toward the blade of the punching device 2 tool.

[0038] When the punching device 2 punches the pearl cotton board, it is necessary to fix the pearl cotton board first. Therefore, a fixing device for fixing the pearl cotton board can be set on the workbench 1. Because the punching device 2 is used to open holes in the pearl cotton board, a blanking hole can be opened at a position corresponding to the hole on the pearl cotton board on the workbench 1, so that the waste generated by opening the hole when the pearl cotton board completes the punching work can fall off through the hole and away from the pearl cotton board, and a collection box is set at a position corresponding to the blanking hole, so that the waste falling through the blanking hole enters the collection box for centralized treatment. At the same time, by setting the blanking hole, it is also possible to avoid the collision between the tool of the punching device and the workbench, thereby avoiding the problem of damage to the tool in the collision.

[0039] When punching holes, the punching device 2 mostly uses an annular tool to complete the punching and cutting work. The blade of the annular tool is mostly designed to be cylindrical. Because the inside of the blade is hollow, the waste generated during punching may enter the blade and get stuck inside the blade. Therefore, an ejector assembly 3 is provided. The ejector assembly 3 can move inside the blade. By starting the ejector assembly 3, the waste stuck in the blade after each punching of the tool is cleaned up, avoiding the waste from accumulating in the tool until the blade is flush, making it difficult for the punching device 2 to complete the punching work in one go.

[0040] In the process of punching holes through the tool by the punching device 2, some debris will also adhere to the blade of the tool. The debris retained on the blade will affect the punching effect of the punching device 2. Therefore, a cleaning component 4 is set on the outside of the tool, and the cleaning component 4 can move on the outer side of the tool and clean the debris retained on the blade during the movement.

[0041] Therefore, in the technical solution provided by the utility model, the ejection component 3 is arranged on the punching device 2, and the ejection component 3 moves toward or away from the cutting edge of the tool of the punching device 2 to push out the waste stuck in the tool of the punching device 2, and the cleaning component 4 is arranged on the outside of the tool of the punching device 2, and the cleaning component 4 is telescopically arranged to clean the debris on the tool of the punching device 2 when the cleaning component 4 contracts toward the cutting edge of the tool of the punching device 2. The waste stuck in the tool of the punching device 2 is ejected by the ejection component 3, and the debris on the tool is cleaned by the cleaning component 4 to prevent the waste and debris from affecting the processing effect of the punching device 2.

[0042] In order to allow the waste pushed out of the tool to fall directly into the collection box instead of falling on the punched pearl cotton board, it is necessary to start the drive assembly when the punching device 2 completes the punching work and the tool has not yet returned. Manually pushing the drive assembly is more dangerous and may collide with the punching device 2. At the same time, manual starting may have a slow response, resulting in no time to push the ejection assembly 3. Therefore, it is most appropriate to set the drive assembly to automatic start.

[0043] Specifically, in an embodiment of the utility model, the ejection assembly 3 includes a driving member 301, a plurality of connecting rods 301 and a plurality of ejection plates 303. The driving member 301 is drivingly connected to a movable plate 304, and the driving member 301 drives the movable plate 304 to move toward or away from the tool of the stamping device 2. The plurality of connecting rods 301 are all arranged on a side of the movable plate 304 facing the tool of the stamping device 2 so that when the movable plate 304 moves toward the cutting edge of the tool of the stamping device 2, the connecting rods 301 are driven to move together. The plurality of ejection plates 303 are respectively arranged at one end of the plurality of connecting rods 301 facing the tool of the stamping device 2, and the ejection plate 303 is slidably connected to the tool of the stamping device 2. The connecting rod 301 drives the ejection plate 303 to move toward the cutting edge of the tool of the stamping device 2 to push out the waste located in the tool of the stamping device 2.

[0044] After the punching device 2 is started, it approaches the pearl cotton board until it contacts the pearl cotton board and starts to punch the pearl cotton board, so that the tool penetrates the pearl cotton board and the blanking port at the same time. At this time, the driving member 301 can be started, so that the driving member 301 drives the movable plate 304 to move in the direction close to the tool, and drives the connecting rod 301 to move together through the movable plate 304, so that the part of the connecting rod 301 located inside the tool gradually increases, so that the ejection plate 303 moves toward the direction of the tool edge with the movement of the connecting rod 301, and gradually pushes the waste inside the tool out of the tool during the movement, so that the waste will not accumulate inside the tool.

[0045] The function of the driving member 301 is to start and drive the movable plate 304 to move linearly in the direction close to the tool under the control of the program. Therefore, the driving member 301 can be set to an electric push rod or a cylinder. After starting, the electric push rod or the cylinder drives the object connected to the output shaft to move linearly through the output shaft. At the same time, the driving member 301 can also be set to a structure composed of a threaded rod and a motor. A relatively simple setting method of this structure is that the threaded rod is threadedly connected in the movable plate 304, and the output shaft of the motor is connected to the threaded rod. When the motor drives the threaded rod to rotate, it can drive the movable plate 304 to move along the extension direction of the thread of the threaded rod, thereby achieving the purpose of driving the movable plate 304 to move linearly.

[0046] Furthermore, the ejection assembly 3 also includes a support box 305, the support box 305 is arranged on the stamping device 2, and the driving member 301 is arranged on the support box 305, and the movable plate 304 is slidably connected in the support box 305, so that the support box 305 limits the movable distance of the movable plate 304.

[0047] The driving member 301 is arranged on the support box 305 so that the driving member 301 will not move after being started, so that after the driving member 301 is started, it will only drive the movable plate 304 to approach the tool, and the driving member 301 itself will not move in the direction away from the movable plate 304, causing the ejection component 3 to fail to complete the purpose of ejecting the waste in the tool. At the same time, the setting of the support box 305 is also to limit the movement of the movable plate 304. After the support box 305 is set, the length of each side of its inner cavity remains unchanged. Therefore, the sliding distance of the movable plate 304 sliding in the support box 305 is also limited. The movement distance of the movable plate 304 is limited by limiting the height of the inner cavity of the support box 305 along the movement direction of the movable plate 304.

[0048] The support box 305 can be installed on the component used to connect the tool and is arranged on the side opposite to the tool, so that the ejection component 3 can easily enter the inside of the tool to clean the waste in the tool.

[0049] When waste materials are retained inside the tool, some debris may be retained. These debris need to be cleaned regularly. However, if the staff cleans them manually, they need to put their hands deep into the tool to clean them. Once an accident causes the equipment to start suddenly, it will cause unpredictable harm to the staff. Therefore, a cleaning structure can be set on the ejector assembly 3 to clean the debris inside the tool while pushing the waste materials.

[0050] Specifically, in an embodiment of the utility model, a first brush is provided on the outer peripheral side of the ejection plate 303, which is in contact with the inner peripheral wall of the tool of the punching device 2, so as to clean the debris on the tool of the punching device 2 when the ejection plate 303 moves toward the cutting edge of the tool of the punching device 2.

[0051] A first brush is provided on the outer peripheral side of the ejection plate 303, and the first brush moves inside the tool together with the ejection plate 303. When the first brush moves toward the cutting edge of the tool together with the ejection plate 303, the debris attached to the inner peripheral wall of the tool can be gradually swept toward the cutting edge of the tool, and the debris can be swept out of the cutting edge, thereby completing the cleaning work inside the tool. The ejection plate 303 is started each time the stamping device 2 performs a stamping work, so that the first brush can clean the inside of the tool each time the stamping device 2 performs a stamping work, thereby improving the cleaning effect. At the same time, the staff does not need to put their hands into the inside of the tool for cleaning, thereby ensuring the safety of the staff.

[0052] The first brush can be tilted toward the cutting edge of the tool so that the first brush can more effectively clean the debris from the tool during the cleaning process. At the same time, the first brush will not completely collide with the cutting edge of the tool when it moves to the outside of the tool and then moves into the tool. Instead, the first brush will avoid the cutting edge of the tool to a certain extent through the tilt of the first brush, thereby reducing the probability of the first brush being cut by the tool.

[0053] When ejecting the waste in the tool, if the ejector plate 303 only moves to the cutting edge, the waste may be stuck at the cutting edge and no longer move. Therefore, the ejector plate 303 needs to be completely moved to the outside of the tool, and the moving distance of the ejector plate 303 is related to the moving distance of the movable plate 304 and the length of the connecting rod 301. The moving distance of the movable plate 304 can be adjusted by changing the height of the support box 305. The connecting rod 301 needs to extend into the tool to drive the ejector plate 303 to move, so the length of the connecting rod 301 needs to be limited. The length of the connecting rod 301 along the moving direction is greater than the height of the tool of the stamping device 2, so that the connecting rod 301 penetrates the tool of the stamping device 2. The connecting rod 301 can penetrate the tool as the movable plate 304 moves, which can drive the ejector plate 303 to move to the outside of the tool, so that the ejector plate 303 can completely push the waste in the tool out of the tool, avoiding the problem of waste being stuck at the cutting edge of the tool.

[0054] The ejector plate 303 needs to be located inside the tool and move linearly toward the cutting edge, so the moving direction of the connecting rod 301 needs to be restricted. A connecting hole for the connecting rod 301 to pass through is provided at one end of the tool of the punching device 2 close to the movable plate 304, and the connecting hole extends toward the cutting edge of the tool of the punching device 2 to limit the moving direction of the connecting rod 301. After the moving direction of the connecting rod 301 is restricted by the connecting hole, the ejector plate 303 can only move linearly toward the cutting edge of the tool under the push of the connecting rod 301, and will not move obliquely and collide with the inner wall of the tool cavity.

[0055] The function of the cleaning component 4 is to clean the debris on the outside of the tool and the debris on the blade by moving outside the tool. There are various structures that can achieve this function. Specifically, in the embodiment of the utility model, the cleaning component 4 includes a connecting member 401, a cleaning plate 403 and an elastic member 404. The connecting member 401 is arranged on the outer peripheral side of the tool of the punching device 2. A linkage rod 402 is slidably connected in the connecting member 401. The linkage rod 402 moves toward or away from the workbench 1. The cleaning plate 403 is arranged at one end of the linkage rod 402 facing the workbench 1. A through hole is provided on the plate 403 for the tool of the punching device 2 to pass through. The cleaning plate 403 moves toward or away from the cutting edge of the tool of the punching device 2. A second brush for cleaning the tool of the punching device 2 is provided on the inner wall of the through hole. The elastic member 404 is provided on the connecting member 401. The elastic member 404 extends toward the moving direction of the linkage rod 402. A limiting plate 405 fixed to the linkage rod 402 is provided at one end of the elastic member 404 away from the connecting member 401. The limiting plate 405 is used to limit the moving distance of the linkage rod 402.

[0056] When the punching device 2 is punching, the tool drives the cleaning component 4 to gradually approach the pearl cotton board on the workbench 1. When the tool and the pearl cotton board are close, the cleaning plate 403 of the cleaning component 4 first fits with the pearl cotton board. At this time, the tool continues to approach the pearl cotton board, and the cleaning plate 403 no longer moves. The connecting piece 401 moves with the tool and gradually approaches the cleaning plate 403, while stretching the spring. At this time, the cleaning plate 403 gradually moves to the outer peripheral side of the tool, and cleans the debris on the outside of the tool through the second brush in the through hole during the movement. When the tool completes the stamping and cutting process and starts to move toward the initial position, it drives the connecting plate to move and gradually separates from the pearl cotton board, so that the spring gradually returns to its original state, and makes the cleaning plate 403 move toward the blade of the tool until it moves to the side of the blade facing the workbench 1. During the movement, the debris on the outside of the tool is cleaned again, and the debris on the blade of the tool is cleaned.

[0057] The automatic start of the drive component can be set by a program or by a trigger structure. For example, a pressure sensor is set on the outer peripheral side of the tool, and the pressure sensor is aligned with the limit plate 405. The limit plate 405 can contact the pressure sensor and apply pressure to the pressure sensor when the linkage rod 402 moves. That is, after the cleaning plate 403 moves toward the tool and moves to the outer peripheral side, the linkage rod 402 drives the limit plate 405 to move with the cleaning plate 403. When the cleaning plate 403 is no longer moving, the stamping device 2 completes the stamping work. At the same time, the limit plate 405 contacts the pressure sensor and applies pressure to the pressure sensor. After receiving the set pressure, the pressure sensor sends a sensor signal to the drive member 301 to start the drive component, and the drive component begins to clean the waste in the tool.

[0058] Furthermore, the second brush is arranged at an angle, and the second brush is inclined toward a side away from the tool of the punching device 2, so that the second brush avoids the blade of the tool of the punching device 2.

[0059] The second brush is more likely to contact the blade of the tool when it moves on the outside of the tool, making it easier for the second brush to be cut off by the tool. Therefore, it is necessary to change the setting method of the second brush so that the second brush is tilted and set in a direction away from the blade of the tool, so that when the second brush contacts the blade of the tool, the blade of the tool can push the second brush away along the inclined surface of the second brush, avoiding the problem of the blade and the second brush directly colliding and causing the second brush to be cut off. At the same time, the second brush is completely located in the through hole of the cleaning plate 403, avoiding the pearl cotton board pushing one end of the second brush upward when the cleaning plate 403 is fitted with the pearl cotton board, making the tilt angle of the second brush smaller, thereby causing the second brush to become easy to collide with the blade and break.

[0060] When the spring rebounds, the linkage rod 402 will drive the cleaning plate 403 to move together, and when the cleaning plate 403 approaches the connecting piece 401, the movement direction of the linkage rod 402 will also affect the movement direction of the cleaning plate 403. In order to prevent the cleaning plate 403 from colliding with the tool during the movement, it is necessary to limit the movement direction of the linkage rod 402. The connecting piece 401 is provided with a limiting hole for the sliding connection of the linkage rod 402, and the limiting hole extends toward the movement direction of the tool of the stamping device 2 to limit the movement direction of the linkage rod 402. The movement direction of the linkage rod 402 is limited by providing the limiting hole, so that the linkage rod 402 can only move toward or away from the workbench 1. At the same time, in order to prevent the linkage rod from shaking too much during the movement, the aperture of the limiting hole can also be limited, so that the aperture of the limiting hole is slightly larger than the diameter of the linkage rod 402, so that the linkage rod 402 is difficult to shake in the limiting hole, thereby making the cleaning plate 403 stable.

[0061] The tool of the punching device 2 moves toward the workbench 1 and needs to complete the punching work. A corresponding structure is required to drive the tool to move, and the corresponding structure needs to give the tool enough thrust to enable the tool to complete the punching and cutting work. Therefore, the punching device 2 includes a driving component, and the tool drive of the punching device 2 is connected to the driving component so that the driving component drives the tool of the punching device 2 to move closer to or away from the workbench 1 for work.

[0062] The driving component with sufficient push-off commonly used in the stamping device 2 is usually a hydraulic cylinder, which drives the lifting plate toward the workbench 1. The tool is set on the lifting plate and moves toward the workbench 1 together with the lifting plate, and completes the punching process under the push of the hydraulic cylinder.

[0063] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
