Description

Technical Field

[0001] This application relates to the field of hygiene protection product manufacturing technology, and in particular to a waste collection device. Background Technology

[0002] Currently, waste edges are frequently generated in some production processes. This is especially true in mask production, where waste edges are generated after the mask body is cut from the raw material; these waste edges are continuous strip-shaped structures. Directly collecting these waste edges through boxes is messy and takes up a lot of space, so winding mechanisms are often used to collect them.

[0003] Existing Chinese patent CN115924631A discloses a waste edge collection device for a bag-making machine, including a mounting frame. The mounting frame is equipped with a winding mechanism and a traction component. The traction component is arranged parallel to the winding mechanism and is used to pull the waste edge to be evenly wound around the winding mechanism. The traction component includes a reciprocating screw and guide posts. Both ends of the reciprocating screw are rotatably connected to the mounting frame. There are two guide posts, located on both sides of the reciprocating screw, and both guide posts are arranged parallel to the reciprocating screw. A movable seat is sleeved on the reciprocating screw and is threadedly connected to the reciprocating screw. The movable seat passes through the guide posts and is slidably connected to the guide posts. A traction rod is provided at the top of the movable seat, and the bottom of the traction rod intersects with the movable seat. A traction ring for the waste edge to pass through is provided at the top of the traction rod.

[0004] Regarding the aforementioned technologies, in order for the waste edge to be evenly wound onto the take-up roller, it is generally necessary to use a traction component to drive the waste edge to move back and forth along the length of the take-up roller. However, most traction components are achieved by the forward and reverse rotation of a lead screw, so the reciprocating motion is affected by the length of the lead screw. When taking up rollers of different lengths are required, lead screws of different lengths need to be replaced, which is inconvenient and therefore needs to be improved. Summary of the Invention

[0005] To facilitate winding with take-up rollers of different lengths, this application provides a waste edge collection device.

[0006] The waste edge collection device provided in this application adopts the following technical solution:

[0007] A waste edge collection device includes: a take-up roller, which is rotatably disposed; and a traction assembly, which is disposed on one side of the take-up roller along its length direction. The traction assembly includes a swing arm, a traction ring, and a driving member. The swing arm is rotatably disposed on one side of the take-up roller at intervals, and the driving member is used to drive the swing arm to swing back and forth. The traction ring is disposed on the swing arm. The pivot of the swing arm is located on one side close to the vertical centerline of the take-up roller, and the plane of rotation of the swing arm is located on one side of the take-up roller. The swing range of the swing arm is adjustable, and the traction assembly is adjustable along the length direction of the take-up roller.

[0008] By adopting the above technical solution, the take-up roller can wind the waste edge when it rotates. Before the waste edge is wound onto the take-up roller, it passes through the traction ring. Then, the drive unit drives the swing arm to swing back and forth on one side of the take-up roller. By controlling the range of the swing arm's reciprocating swing, it is ensured that the swing arm can drive the traction ring to move back and forth on one side of the take-up roller along its length, thereby driving the waste edge to be evenly wound around the outside of the take-up roller. When the length of the take-up roller changes, the position of the traction component and the swing range of the swing arm can be adjusted so that the traction ring can move from one end of the take-up roller to the other when the swing arm swings, adapting to take-up rollers of different lengths and facilitating winding with take-up rollers of different lengths. Moreover, when it is necessary to adjust the length of the wound waste edge, the swing range of the swing arm can be directly adjusted.

[0009] Preferably, the traction ring is slidably disposed on the swing arm, the traction ring slides freely along the length direction of the swing arm, and the traction ring is located at the end of the swing arm away from the axis of rotation.

[0010] By adopting the above technical solution, when the swing arm swings back and forth, the winding roller is winding at a constant speed. Therefore, the traction ring will be subjected to the external force of the waste edge, which allows the traction ring to slide back and forth in the length direction of the swing arm, reducing the distance fluctuation between the traction ring and the outer side of the winding roller, and ensuring that the winding roller can wind the waste edge stably.

[0011] Preferably, it further includes a mounting frame, with both ends of the take-up roller rotatably connected to the mounting frame, and a mounting part slidably connected to the mounting frame. The sliding direction of the mounting part is parallel to the length direction of the take-up roller, and the traction assembly is disposed on the mounting part.

[0012] By adopting the above technical solution, the installation part can facilitate the support and installation of the traction component. By adjusting the sliding of the installation part, the entire traction component can be adjusted synchronously.

[0013] Preferably, the pivot height of the swing arm is lower than the lowest position of the take-up roller.

[0014] By adopting the above technical solution, the pivot of the swing arm is lower than the lowest position of the take-up roller. Therefore, the swing arm has a smaller rotation angle and a shorter length, which ensures that the rotation range of the swing arm covers the length of the take-up roller.

[0015] Preferably, it further includes a chip collection cover disposed on the other side of the winding roller along its length, the opening of the chip collection cover facing the winding roller, and a chip extraction assembly disposed on the chip collection cover.

[0016] By adopting the above technical solution, since the waste edges are left after cutting, and most of the waste edges from mask production are non-woven fabric, there will be some debris generated; the debris collection cover can cover one side of the waste edge wound by the take-up roller, and the debris can be absorbed by the debris extraction component, reducing the impact of debris on the workshop environment.

[0017] Preferably, the chip collection hood and the swing arm are located on the horizontal sides of the take-up roller, and the side of the swing arm facing the take-up roller is provided with a fan plate.

[0018] By adopting the above technical solution, when the swing arm rotates, it synchronously drives the fan plate to swing, thereby generating a certain blowing force to better blow the debris into the debris collection hood for collection.

[0019] Preferably, the fan plate is provided with a plurality of flexible scrapers at intervals on the side near the take-up roller.

[0020] By adopting the above technical solution, the flexible scraper has a certain elastic deformation capability. When the fan plate is rotating and the outer diameter of the waste edge roll gradually increases, the flexible scraper can scrape the waste edge wound on the take-up roller to sweep off the debris on the waste edge. The debris is finally sucked into the debris collection hood to collect the debris on the waste edge more comprehensively.

[0021] Preferably, the fan plate is rotatably connected to the swing arm, and the rotation axis of the fan plate is set along the length direction of the swing arm; when the swing arm rotates, the fan plate and the swing arm reciprocate.

[0022] By adopting the above technical solution, when the swing arm swings back and forth, the fan plate is subjected to a certain amount of swinging, so the fan plate can rotate, increasing the blowing force of the fan plate towards the opening of the chip collection hood, so as to better blow the debris into the opening of the chip collection hood.

[0023] Preferably, an elastic reset member is provided on one side of the fan plate, and the other end of the elastic reset member is connected to the swing rod. The elastic reset member is used to drive the fan plate to rotate to a position on the same plane as the swing rod. When the swing rod rotates to the vertical position, the fan plate and the swing rod are on the same plane, and the elastic reset member is in its natural state.

[0024] By adopting the above technical solution, the free rotation of the fan plate can be restricted by the elastic reset component, so that the fan plate always tends to rotate in the same direction as the swing arm, reducing the impact and noise that the fan plate is subjected to when it rotates freely.

[0025] Preferably, a baffle is provided at intervals on the side of the swing arm away from the take-up roller, and the baffle blocks one side of the take-up roller in the length direction.

[0026] By adopting the above technical solution, when the take-up roller rotates and winds the waste edge, a certain amount of airflow is generated, which causes some of the debris remaining on the waste edge to be blown away to the surrounding area and cannot be sucked into the chip collection hood for collection; however, the baffle can block one side of the take-up roller, thereby reducing the outward dispersion of debris from the opening of the chip collection hood and improving the chip collection effect of the chip collection hood.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] (1) By setting the cooperation between the take-up roller, the swing arm, the traction ring and the drive component, the traction ring moves back and forth between the two ends of the take-up roller by swinging. When the length of the take-up roller changes, only the position of the traction component and the rotation angle range of the swing arm need to be adjusted to make it suitable for take-up rollers of different lengths, so as to make it easy to use take-up rollers of different lengths for winding. Moreover, when the length of the waste edge roll to be wound changes, only the swing range of the swing arm needs to be changed.

[0029] (2) By setting up the cooperation between the chip collection hood, chip extraction component and fan plate, when the swing arm swings, it drives the fan plate to swing. The fan plate can generate blowing force to better blow the chips generated when the waste edge is rolled towards the chip collection hood, which facilitates the comprehensive collection of chips.

[0030] (3) By setting up a flexible scraper, when the swing arm swings, the flexible scraper can contact the waste edge wound on the outside of the take-up roller, so as to directly sweep off some of the residual debris and suck it into the chip collection hood, thereby reducing the impact of debris generated during subsequent unwinding and transfer of the waste edge on the surrounding environment.

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This application discloses a waste edge collection device. (Refer to...) Figure 1 The waste edge collection device includes a mounting frame 1, a winding roller 2, and a traction assembly 3.

[0038] The take-up roller 2 is horizontally positioned, and both ends of the take-up roller 2 are rotatably connected to the mounting frame 1. A motor 4 for driving the rotation of the take-up roller 2 is mounted on one end of the mounting frame 1. A mounting part 5 is slidably connected to one side of the bottom of the mounting frame 1. The mounting part 5 is flat, and the sliding direction of the mounting part 5 is parallel to the length direction of the take-up roller 2. A traction assembly 3 is disposed on the mounting part 5.

[0039] Reference Figure 1 and Figure 2 A first slide rail 6, parallel to the length direction of the take-up roller 2, is fixed at the bottom of the mounting frame 1. One side of the mounting part 5 is slidably connected to the first slide rail 6. An adjusting bolt 7, vertically threaded and abutting against the first slide rail 6, is attached to the mounting part 5. The end of the adjusting bolt 7 passes through the mounting part 5 and abuts against the outside of the first slide rail 6, thereby adjusting the sliding position of the mounting part 5. Traction components 3 are spaced apart on one side of the length direction of the take-up roller 2 and are located on the mounting part 5, thus enabling adjustment of the traction components 3 along the length direction of the take-up roller 2.

[0040] Reference Figure 2 and Figure 3The traction assembly 3 includes a swing arm 31, a traction ring 32, and a drive component 33. The lower end of the swing arm 31 is rotatably mounted on the mounting part 5, and the traction ring 32 is located at the end of the swing arm 31 away from the mounting part 5. The drive component 33 is located on the mounting part 5 and is used to drive the swing arm 31 to swing back and forth. The drive component 33 is selected as a servo motor 4. By adjusting the electrical control signal of the servo motor 4, the range of back and forth swing of the swing arm 31 can be controlled, thereby adjusting the swing range of the swing arm 31. It also ensures that when the swing arm 31 swings, the traction ring 32 can approach the two end faces of the take-up roller 2 and swing back and forth between the two end faces of the take-up roller 2. The rotation axis of the swing arm 31 is horizontally set and perpendicular to the plane where the take-up roller 2 is located. The rotation axis of the swing arm 31 is located on the side close to the vertical center line of the take-up roller 2, and the height of the rotation axis of the swing arm 31 is lower than the lowest position of the take-up roller 2. The rotation plane of the swing arm 31 is located on one side of the take-up roller 2.

[0041] In this embodiment, when the swing arm 31 is in a vertical position or at its maximum angle to the vertical position, the traction ring 32 is always positioned higher than the upper side of the take-up roller 2; and when the swing arm 31 rotates to its maximum angle with the vertical position, the traction ring 32 is located near the end of the take-up roller 2. Therefore, when collecting waste strips, the waste strips are first passed through the traction ring 32 and then wound around the take-up roller 2. Then, the swing arm 31 is driven to swing back and forth by the drive member 33, thereby driving the traction ring 32 to move back and forth between the two ends of the take-up roller 2, so as to guide the waste strips to be evenly wound around the outside of the take-up roller 2.

[0042] When the length of the take-up roller 2 changes, the position of the mounting part 5 can be slidably adjusted so that the mounting part 5 and the traction assembly 3 are close to the middle position of the take-up roller 2. The swing range of the swing arm 31 can be adjusted by regulating the electrical control signal of the servo motor 4, ensuring that the traction ring 32 can reciprocate between the two end faces of the take-up roller 2 when the swing arm 31 rotates, to accommodate take-up rollers 2 of different lengths. Simultaneously, when it is necessary to adjust the length of the wound waste edge roll, this can be achieved directly by adjusting the swing range of the swing arm 31.

[0043] In some embodiments, the drive member 33 can be selected as a cylinder, a gear, and a rack. The rack is fixed to the end of the telescopic rod of the cylinder, the gear is fixed to the rotating shaft of the rocker arm 31, and the gear and the rack mesh with each other. When the cylinder moves in extension and retraction, it can drive the rocker arm 31 to reciprocate. In other embodiments, the cylinder can be selected as a hydraulic cylinder. By controlling the extension and retraction stroke of the cylinder or hydraulic cylinder, the swing range of the rocker arm 31 can be driven.

[0044] In some embodiments, the traction ring 32 is slidably disposed on the swing arm 31, and the traction ring 32 slides freely along the length direction of the swing arm 31. The traction ring 32 can be slidably connected to the swing arm 31 through the cooperation of the slider 8 and the second slide rail 9. The second slide rail 9 is disposed along the length direction of the swing arm 31, the slider 8 slides on the second slide rail 9, and the traction ring 32 is fixed to the slider 8. Since the distance between the traction ring 32 and the outer side of the take-up roller 2 changes significantly when the swing arm 31 reciprocates, the traction ring 32, which slides on one end of the swing arm 31, slides on the swing arm 31 when the swing arm 31 rotates, so that the traction ring 32 can move between the two ends of the take-up roller 2 in a straight line direction that is nearly parallel to the take-up roller 2, ensuring that the waste edge is smoothly wound on the take-up roller 2. When the swing arm 31 swings from one end of the take-up roller 2 to the other end of the take-up roller 2, the traction ring 32 first moves towards the mounting part 5 on the swing arm 31, and then gradually moves away from the mounting part 5.

[0045] In some embodiments, refer to Figure 1 and Figure 3 A chip collection cover 10 is installed at intervals on the other side of the winding roller 2 along its length. The opening of the chip collection cover 10 faces horizontally towards one side of the winding roller 2 along its length. The chip collection cover 10 and the swing rod 31 are located on the horizontal sides of the winding roller 2. A chip extraction assembly 11 is provided on the chip collection cover 10. Because the environmental hygiene requirements are high during mask production, and there are still chips on the waste edges left after cutting, chips will spill into the surrounding environment during the winding process. The chip collection cover 10 can cover one side of the waste edge roll, so that some of the chips can be absorbed and collected by the chip extraction assembly 11, reducing the impact of chips on the environment.

[0046] The chip extraction assembly 11 includes an exhaust pipe 111, an exhaust fan 112, and a collection bucket 113. One end of the exhaust pipe 111 is connected to the back of the chip collection hood 10, and the exhaust fan 112 is installed at the other end of the exhaust pipe 111. The collection bucket 113 is connected to the exhaust outlet of the exhaust pipe 111. The chips inside the chip collection hood 10 can be drawn into the collection bucket 113.

[0047] In some embodiments, a fan plate 12 is provided on the side of the swing arm 31 facing the take-up roller 2. The fan plate 12 is arranged along the length direction of the swing arm 31. When the swing arm 31 swings, the fan plate 12 swings accordingly, which can generate some blowing force to better blow the debris into the opening of the debris collection hood 10, so that the overflowing debris is absorbed more comprehensively.

[0048] In some embodiments, a plurality of flexible scraper strips 13 are fixed at intervals on the side of the fan plate 12 near the take-up roller 2. The flexible scraper strips 13 are made of rubber sheet material, which has a certain elastic deformation capability to ensure that the outer diameter of the waste edge roll is not affected as it gradually increases. When the outer diameter of the waste edge roll gradually increases, the flexible scraper strips 13 can elastically abut against the waste edge roll wound on the outside of the take-up roller 2. Since some residual debris on the surface of the wound waste edge roll will fall and spill when it is unwound or transferred, the flexible scraper strips 13 can directly contact part of the waste edge during the winding process, thereby directly knocking off the debris. At the same time, it can better blow away some of the debris remaining on the waste edge. Then the debris is sucked into the debris collection hood 10, reducing the debris remaining on the waste edge, reducing the diffusion of debris during the subsequent transfer of the waste edge roll, and further reducing the impact of debris on the sanitary environment.

[0049] In some embodiments, the fan plate 12 is rotatably connected to the swing arm 31, and the axis of rotation of the fan plate 12 is arranged along the length direction of the swing arm 31. When the swing arm 31 rotates, the fan plate 12 and the swing arm 31 reciprocate within a certain range. During the reciprocating swing of the swing arm 31, the fan plate 12 is subjected to a certain amount of swinging, so the fan plate 12 and the swing arm 31 can rotate relative to each other, thereby increasing the blowing force of the fan plate 12 toward the opening of the chip collection hood 10, so as to better blow the debris into the opening of the chip collection hood 10.

[0050] An elastic reset member 14 is fixed to one side of the fan plate 12. The elastic reset member 14 is selected as a spring or a rubber strip. The other end of the elastic reset member 14 is connected to the swing rod 31. The elastic reset member 14 is used to drive the fan plate 12 to rotate to a position on the same plane as the swing rod 31. When the swing rod 31 rotates to the vertical position, the fan plate 12 and the swing rod 31 are on the same plane, and the elastic reset member 14 is in a natural state. When the fan plate 12 starts to rotate to both sides from the position on the same plane as the swing rod 31, the elastic reset member 14 is compressed or stretched. When the swing rod 31 swings back and forth, the fan plate 12 will be subjected to a certain amount of swinging, so that the fan plate 12 rotates. The elastic reset member 14 can limit the free rotation of the fan plate 12 and limit the rotation range of the fan plate 12, so that the fan plate 12 always has the tendency to rotate in the direction on the same plane as the swing rod 31, reducing the impact and noise generated when the fan plate 12 rotates freely, and ensuring that the fan plate 12 can blow air towards the take-up roller 2.

[0051] In some embodiments, refer to Figure 1 and Figure 4A baffle 15 is fixed at intervals on the side of the swing arm 31 away from the take-up roller 2. The lower end of the baffle 15 is connected to the bottom of the mounting frame 1. The baffle 15 blocks one side of the take-up roller 2 along its length, and the baffle 15 is opposite to the opening of the chip collection hood 10. Because the take-up roller 2 generates a certain airflow when rotating and winding the waste edge, some debris is blown into the surrounding environment and cannot be sucked into the chip collection hood 10 for collection. The baffle 15 can block one side of the take-up roller 2, thereby reducing the outward dispersion of debris from the opening of the chip collection hood 10 and improving the chip collection effect of the chip collection hood 10.

[0052] The implementation principle of the waste edge collection device in this application embodiment is as follows: when winding waste edge, one end of the waste edge is passed through the traction ring 32, and then the waste edge is wound around the outside of the take-up roller 2; then the drive member 33 drives the swing rod 31 to swing back and forth, and the traction ring 32 can slide on the swing rod 31, so that the waste edge is evenly and stably wound around the outside of the take-up roller 2; when the swing rod 31 swings, the fan plate 12 also swings, which can generate a blowing force to blow some debris into the chip collection hood 10, thereby improving the comprehensive collection of debris.

[0053] When the length of the take-up roller 2 changes, the position of the mounting part 5 can be slidably adjusted and fixed by the adjusting bolt 7, so that the mounting part 5 and the traction assembly 3 are close to the middle position of the take-up roller 2. The swing range of the swing arm 31 can be adjusted by adjusting the electrical control signal of the servo motor 4, so that when the swing arm 31 rotates, the traction ring 32 can move back and forth between the two ends close to the take-up roller 2, thus making it suitable for take-up rollers 2 of different lengths, and realizing convenient take-up of take-up rollers 2 of different lengths.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
