Description

Technical Field

[0001] This application relates to the field of glitter powder processing technology, and in particular to a glitter powder feeding and collection device. Background Technology

[0002] Glitter powder is a glittery decorative material made from PET, PVC, OPP, or aluminum film through electroplating, coating, and cutting. During the production and processing of glitter powder, it is usually necessary to collect it using collection containers.

[0003] In existing technologies, when collecting glitter powder, a collection container is often placed below a feeding tank, with its opening aligned with the discharge pipe of the feeding tank. The glitter powder enters the collection container through the discharge pipe. However, if the discharge pipe and the collection container remain relatively stationary during the feeding process, the falling glitter powder tends to accumulate in a localized area of ​​the container, forming a cone-shaped area inside. This results in empty spaces within the container, wasting storage space and affecting collection efficiency. Therefore, to avoid this situation, existing technologies employ methods such as rotating the discharge pipe and vibrating the collection container to ensure the glitter powder is evenly distributed within the collection container.

[0004] However, even with continuous rotation of the discharge pipe, it is difficult to ensure that the discharge range of glitter powder evenly covers the collection container. When the discharge pipe rotates, the glitter powder still mainly falls along a ring-shaped area, and blind spots are easily formed in the center and edge areas of the container. The distribution of glitter powder in these areas is significantly less, and the uniformity is still poor. Moreover, vibration will cause the movement trajectory of glitter powder to be irregular, which can easily lead to local accumulation of glitter powder in the container or even splashing outside the container, making it difficult to achieve the expected uniform spreading effect. Summary of the Invention

[0005] Therefore, it is necessary to provide a glitter powder feeding and collection device to address the aforementioned technical problems.

[0006] A glitter powder feeding and collecting device includes a base, a bracket fixedly connected to the base, a feeding tank for holding glitter powder fixedly mounted on the bracket, a discharge pipe at the bottom of the feeding tank, and a diameter-adaptive spreading component on the base. The diameter-adaptive spreading assembly includes multiple scrapers arranged linearly in the transverse direction. The inner cavity of each scraper is equipped with a take-up and release roller, and a filling cloth is wound on the take-up and release roller. The filling cloth passes through the side wall of the scraper, and the end of the filling cloth is fixedly connected to another adjacent scraper. The multiple scrapers and multiple filling cloths cooperate with each other to form a scraping structure that matches the inner diameter of the collection container. The base is also equipped with a rotary lifting drive mechanism for driving the scraping structure to rise and rotate; the scraping structure extends into the inner cavity of the collection container and rotates under the drive of the rotary lifting drive mechanism, spreading the glitter powder in the collection container evenly.

[0007] Preferably, the base is provided with a clamping structure for fixing the collection container; The clamping structure includes two cylinders symmetrically arranged on both sides of the base, and a positioning block is fixedly connected to the piston end of each cylinder.

The middle slider is fixedly mounted on the rotating frame, and the remaining sliders are slidably mounted on the rotating frame in the transverse direction. An adjusting rod is fixedly connected to the bottom of each slider, and the bottom of the adjusting rod is fixedly connected to a scraper. Two cylinders are fixedly mounted at both ends of the rotating frame, and the piston ends of the two cylinders are fixedly connected to the sliders on both sides respectively. The multiple sliders are connected by a connecting rod assembly.

[0010] Preferably, a spring is sleeved on one end of the take-up and release roller, one end of which is fixedly connected to the end of the take-up and release roller, and the other end is fixedly connected to the inner wall of the scraper cavity.

[0011] Preferably, the rotating frame is provided with a uniformly distributed flipping structure; The uniformly distributed flipping structure includes multiple sliding cylinders, each of which is fixedly mounted on an adjusting rod. A lifting rod slides through the inner cavity of the sliding cylinder. Multiple toothed plates are fixedly connected to the bottom of the lifting rod along the circumferential direction. The sliding cylinder is provided with a spiral sliding groove. A guide post is fixedly connected to the lifting rod, and the guide post slides through the spiral sliding groove.

[0012] Preferably, the upper end of the lifting rod is provided with a sliding sleeve, the rotating frame is provided with a guide rod that slides vertically through it, the bottom of the guide rod is fixedly connected to a synchronizing rod, multiple sliding sleeves are jointly provided on the synchronizing rod that slides horizontally, and a cylinder is fixedly provided on the rotating frame, the piston end of the cylinder is fixedly connected to one end of the synchronizing rod.

[0013] Preferably, the base is provided with a container edge protection component; The container edge protection assembly includes two sleeves symmetrically distributed on both sides of the base. The sleeves are equipped with cloth rollers that rotate within their inner cavities, and the two cloth rollers are wound together with spill-proof cloth.

[0014] Preferably, the base is provided with two sets of displacement structures symmetrically. The displacement structure includes a second upright frame fixedly connected to a base, a third linear screw module on the second upright frame, a lifting frame fixedly mounted on the moving end of the third linear screw module, a second linear screw module on the lifting frame, a moving seat fixedly mounted on the moving end of the second linear screw module, a rack slidably mounted on the moving seat, two sleeves fixedly connected to the ends of the two racks respectively, a gear rotatably mounted on the moving seat, the gear meshing with the rack, and a third motor fixedly mounted on the moving seat for driving the gear to rotate.

[0015] Preferably, a second motor for driving the cloth roller to rotate is fixedly installed on the sleeve, a scraper is slidably inserted into the side wall of the sleeve, one end of the scraper is fixedly connected to a spring, the other end of the spring is fixedly connected to the side wall of the sleeve, and the scraper is in contact with the surface of the anti-overflow cloth.

[0016] The beneficial effects of this invention are as follows: 1. The glitter powder feeding and collecting device of the present invention utilizes a diameter-adaptive spreading component. When the glitter powder enters the container through the feeding tank, the scraping structure rotates inside the container to scrape and spread the glitter powder falling into the container. At the same time, as the amount of glitter powder in the container gradually increases, the scraping structure rises accordingly to adapt to the accumulation height of the glitter powder in the container, thereby forming a uniform spreading effect in the inner cavity of the container and avoiding excessive accumulation of glitter powder in local areas to form cone-shaped bodies, effectively improving the space utilization rate of the collecting container.

[0017] Furthermore, because the scraping structure exerts a stable and controllable leveling effect on the glitter powder during rotation, and its working range is adapted to the inner diameter of the container, it can achieve scraping of the container's internal area without dead angles. This replaces the existing technology that relies on the rotation of the discharge pipe and the vibration of the container for material uniformity. This eliminates the blind spots caused by the rotation of the discharge pipe and avoids the problems of irregular movement trajectory, splashing, or re-accumulation of glitter powder caused by vibration, significantly improving the collection efficiency and quality of glitter powder.

[0018] Furthermore, compared to using extendable plates to adapt to the inner diameter of containers, this method uses multiple variable-pitch scrapers combined with retractable filling cloth to form a scraping structure. Since the scrapers can achieve large-stroke extension and retraction adjustment through variable pitch, and the filling cloth can be retracted and expanded synchronously with the change of scraper spacing to fill the gaps between adjacent scrapers, the adjustable span of the scraping structure is larger and the retraction and expansion are more flexible. This allows it to adapt to more collection containers with different inner diameters, improving the versatility of the equipment.

[0019] 2. The glitter powder feeding and collecting device of the present invention utilizes a uniformly distributed turning structure. During the rotation of the rotating frame, the lifting rod can perform a compound motion of revolution, rotation, and lifting, and the toothed plates can be inserted into the glitter powder. The stirring of the toothed plates breaks up the arching or agglomeration of the glitter powder. Furthermore, the distance between adjacent toothed plates depends on the distance between adjacent scrapers, so the stirring range of multiple toothed plates will be consistent with the scraping range of the scraping structure.

[0020] Specifically, since the spacing between adjacent toothed plates changes synchronously with the spacing between adjacent scrapers, after the scrapers adjust their spacing according to the container's inner diameter and adhere to the container's inner wall, multiple toothed plates also form a distribution in the container's radial direction that adapts to the scraping range. In this way, as the toothed plates revolve with the scraping structure, they can maximize the agitation range covering the entire radial area acted upon by the scraping structure, ensuring that the glitter powder in each area of ​​the container is effectively agitated. This breaks down arching and agglomeration, causing the glitter powder to redisperse and become denser, further improving the utilization rate and actual effective capacity of the container's internal space.

[0021] 3. The glitter powder collection device of this invention utilizes a container edge protection component. During the collection process, an anti-overflow cloth surrounds the container opening and is tightly fitted to the outer wall of the container under the winding of the cloth roller. This creates a barrier higher than the container opening, ensuring that even if the toothed plate stirs the glitter powder, the powder is blocked by the barrier and falls back into the container, effectively preventing glitter powder from overflowing from the container opening edge, reducing material waste, and ensuring the continuity of the collection process and the accuracy of the collected amount. Furthermore, because the anti-overflow cloth can be adjusted according to the container height and is tightly fitted to the outer wall of the container through the winding and unwinding of the cloth roller, it can be adapted to collection containers of different heights and diameters, further improving the versatility and reliability of the equipment.

[0022] 4. The glitter powder feeding and collecting device of the present invention, after the feeding operation is completed and before the container is removed from the feeding tank, unrolls the anti-overflow cloth on one side and rewinds it on the other side, causing the anti-overflow cloth to move along the outer wall of the container. During the movement of the anti-overflow cloth, the glitter powder accumulated in the angled area between the anti-overflow cloth and the inner wall of the container will move along with it due to the friction of the anti-overflow cloth, thereby dispersing the accumulated glitter powder and making it easier to fall back into the container. This prevents the glitter powder accumulated at the edge of the container opening from scattering outside the container due to the loss of the support of the anti-overflow cloth when the container is removed, further avoiding material loss and environmental pollution.

[0023] 5. In the glitter powder feeding and collecting device of the present invention, the scraper is pressed against the contact surface between the anti-overflow cloth and the glitter powder under the action of the spring. Therefore, before the anti-overflow cloth is put into the sleeve, the scraper will scrape the surface of the anti-overflow cloth, causing the glitter powder attached to the surface of the anti-overflow cloth to fall off, so that the glitter powder can fall back into the container when the anti-overflow cloth enters the sleeve, thereby further recycling materials, reducing waste, and also avoiding the smoothness of subsequent feeding and receiving due to the glitter powder attached to the surface of the anti-overflow cloth.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] Example 1: like Figure 1 , Figure 3 , Figure 7 As shown, a glitter powder feeding and collecting device includes a base 1, a bracket 3 fixedly connected to the base 1, a feeding tank 2 for holding glitter powder fixedly mounted on the bracket 3, a discharge pipe at the bottom of the feeding tank 2, and a diameter-adaptive spreading component on the base 1. The diameter-adaptive material spreading assembly includes multiple scrapers 15 arranged linearly in the transverse direction. The inner cavity of the scraper 15 is provided with a take-up and release roller 25. A filling cloth 26 is wound on the take-up and release roller 25. The filling cloth 26 passes through the side wall of the scraper 15, and the end of the filling cloth 26 is fixedly connected to another adjacent scraper 15. The multiple scrapers 15 and multiple filling cloths 26 cooperate with each other to form a scraping structure that matches the inner diameter of the collection container. The base 1 is also equipped with a rotary lifting drive mechanism for driving the scraping structure to lift and rotate; the scraping structure extends into the inner cavity of the collection container and rotates under the drive of the rotary lifting drive mechanism, spreading the glitter powder in the collection container.

[0028] like Figure 2 and Figure 3 As shown, the base 1 is equipped with a clamping structure for fixing the collection container; The clamping structure includes two cylinders 6 symmetrically arranged on both sides of the base 1, and a positioning block 8 is fixedly connected to the piston end of the cylinder 6.

[0029] like Figure 3 and Figure 4As shown, the rotary lifting drive mechanism includes a stand 4 fixedly mounted on the base 1, a lead screw linear module 7 mounted on the stand 4, a lifting plate 11 fixedly mounted on the moving end of the lead screw linear module 7, a rotating frame 12 rotatably mounted on one end of the lifting plate 11, and a motor 16 mounted on the lifting plate 11 for driving the rotating frame 12 to rotate.

[0030] like Figure 4 and Figure 6 As shown, the rotating frame 12 is equipped with a variable pitch structure; The variable pitch structure includes multiple sliders 17 arranged equidistantly in the transverse direction, and the multiple sliders 17 are symmetrically distributed with the slider 17 located in the middle position as the center of symmetry. The slider 17 located in the middle position is fixedly mounted on the rotating frame 12, and the remaining sliders 17 are slidably mounted on the rotating frame 12 in the transverse direction. An adjusting rod 22 is fixedly connected to the bottom of the slider 17, and the bottom of the adjusting rod 22 is fixedly connected to the scraper 15. Two cylinders 13 are fixedly mounted at both ends of the rotating frame 12, and the piston ends of the two cylinders 13 are fixedly connected to the sliders 17 on both sides respectively. The multiple sliders 17 are connected by a connecting rod group 18.

[0031] like Figure 7 As shown, a spring 24 is sleeved on one end of the take-up and release roller 25. One end of the spring 24 is fixedly connected to the end of the take-up and release roller 25, and the other end is fixedly connected to the inner wall of the scraper 15.

[0032] Specifically, this embodiment is applied to a cylindrical collection container. First, the container is placed between two positioning blocks 8. The cylinder 6 drives the two positioning blocks 8 to move synchronously and approach the outer wall of the container, thus clamping and fixing the container in place. The axis of the fixed container coincides with the axis of rotation of the rotating frame 12. Then, the linear screw module 7 drives the lifting plate 11 to descend, allowing the scraping structure formed by multiple scrapers 15 and multiple filling cloths 26 to extend into the bottom of the container cavity.

[0033] Subsequently, based on the inner diameter of the container, the cylinders 13 on both sides are activated simultaneously. The cylinders 13 drive the sliders 17 on both sides to move laterally on the rotating frame 12. Furthermore, under the transmission of the connecting rod assembly 18, multiple sliders 17 other than the middle one can also move synchronously, thus changing the distance between adjacent sliders 17. In addition, the connecting rod assembly 18 and the cylinder 13 are common transmission structures in existing variable pitch technology, which will not be elaborated further here.

[0034] When the slider 17 moves, the corresponding scraper 15 also moves accordingly. Furthermore, since the end of the take-up and release roller 25 is equipped with a spring 24, when the distance between adjacent scrapers 15 changes, the take-up and release roller 25 will overcome the torque of the spring 24 and rotate, keeping the filling cloth 26 taut until the scrapers 15 on both sides are in contact with the inner wall of the container. At this point, the length of the scraping structure is adapted to the inner diameter of the container.

[0035] At this time, the valve on the discharge pipe at the bottom of the feeding tank 2 is opened, and the glitter powder in the feeding tank 2 will flow into the container through the discharge pipe. At the same time, the rotating frame 12 is driven by the motor 16 to rotate, and the scraping structure rotates inside the container to scrape and spread the glitter powder falling into the container. Meanwhile, as the amount of glitter powder in the container gradually increases, the scraping structure rises under the drive of the lead screw linear module 7 to adapt to the accumulation height of the glitter powder in the container, thereby forming a uniform distribution effect in the inner cavity of the container and avoiding excessive accumulation of glitter powder in local areas to form cone-shaped bodies, effectively improving the space utilization rate of the collection container.

[0036] Furthermore, because the scraping structure exerts a stable and controllable leveling effect on the glitter powder during rotation, and its working range is adapted to the inner diameter of the container, it can achieve scraping of the container's internal area without dead angles. This replaces the existing technology that relies on the rotation of the discharge pipe and the vibration of the container for material uniformity. This eliminates the blind spots caused by the rotation of the discharge pipe and avoids the problems of irregular movement trajectory, splashing, or re-accumulation of glitter powder caused by vibration, significantly improving the collection efficiency and quality of glitter powder.

[0037] Furthermore, compared to using extendable plates to adapt to the inner diameter of containers, this solution uses multiple variable-pitch scrapers 15 in conjunction with retractable filling cloth 26 to form a scraping structure. Since the scrapers 15 can achieve large-stroke extension and retraction adjustment through variable pitch, and the filling cloth 26 can be retracted and extended synchronously with the change of the spacing between the scrapers 15, the adjustable span of the scraping structure is larger and the retraction and extension are more flexible. This allows it to adapt to more collection containers with different inner diameters, improving the versatility of the equipment.

[0038] Example 2: like Figure 4 and Figure 5 As shown, the rotating frame 12 is equipped with a uniformly distributed flipping structure; The uniformly distributed flipping structure includes multiple sliding cylinders 27, each of which is fixedly mounted on an adjusting rod 22. A lifting rod 21 is slidably inserted through the inner cavity of the sliding cylinder 27. Multiple toothed plates 29 are fixedly connected to the bottom of the lifting rod 21 along the circumferential direction. The sliding cylinder 27 is provided with a spiral sliding groove. A guide post 28 is fixedly connected to the lifting rod 21 and slides through the spiral sliding groove.

[0039] like Figure 4 As shown, a sliding sleeve 23 is rotatably provided on the upper end of the lifting rod 21, and a guide rod 19 is slidably passed through the rotating frame 12 along the vertical direction. A synchronizing rod 20 is fixedly connected to the bottom of the guide rod 19. Multiple sliding sleeves 23 are slidably provided on the synchronizing rod 20 along the horizontal direction. A cylinder 3 14 is fixedly provided on the rotating frame 12, and the piston end of the cylinder 3 14 is fixedly connected to one end of the synchronizing rod 20.

[0040] Specifically, in the above embodiments, although the glitter powder in the container can be spread out by the scraping structure, when the glitter powder is in the container, some areas of the glitter powder may clump or agglomerate due to moisture or surface adhesion, resulting in larger gaps between the glitter powder particles. Moreover, the scraping effect of the scraping structure alone is not enough to effectively break up the clumping or agglomeration, and it is still difficult to make full use of the internal space of the container, which to some extent limits the actual effective capacity of the collection container.

[0041] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: During the rotation of the rotating frame 12, the synchronizing rod 20 also rotates synchronously. Furthermore, the synchronizing rod 20 is driven to slide up and down repeatedly by the cylinder 3 14, so the lifting rod 21 also slides vertically in the sliding groove cylinder 27. At the same time as the lifting rod 21 slides, the guide column 28 also slides in the spiral groove on the sliding groove cylinder 27, and under the guidance of the spiral groove, the lifting rod 21 rotates, so that the lifting rod 21 performs a compound motion of revolution, rotation, and lifting, and causes the toothed plate 29 to extend into the glitter powder. The agitation of the toothed plate 29 breaks up the arching or agglomeration of the glitter powder. Furthermore, the distance between adjacent toothed plates 29 depends on the distance between adjacent scrapers 15, so the agitation range of multiple toothed plates 29 will be consistent with the scraping range of the scraping structure.

[0042] Specifically, since the spacing between adjacent toothed plates 29 changes synchronously with the spacing between adjacent scrapers 15, after the scrapers 15 adjust their spacing according to the container's inner diameter and adhere to the container's inner wall, the multiple toothed plates 29 also form a distribution in the container's radial direction that adapts to the scraping range. In this way, as the toothed plates 29 revolve with the scraping structure, they can maximize the agitation range covering the entire radial area acted upon by the scraping structure, ensuring that the glitter powder in each area of ​​the container is effectively agitated. This breaks down arching and agglomeration, causing the glitter powder to redisperse and become denser, further improving the utilization rate and actual effective capacity of the container's internal space.

[0043] In addition, cylinder 14 and guide rod 19 are not higher than lifting plate 11, so they do not interfere with the normal rotation of rotating frame 12.

[0044] Example 3: like Figure 8 and Figure 9 As shown, the base 1 is equipped with a container edge protection assembly; The container edge protection assembly includes two sleeves 31 symmetrically distributed on both sides of the base 1. The sleeves 31 have a cloth roller 32 rotatably mounted inside, and the two cloth rollers 32 are wrapped with an anti-overflow cloth 30.

[0045] like Figure 2 , Figure 3 , Figure 8 , Figure 9 As shown, two sets of displacement structures are symmetrically arranged on the base 1; The displacement structure includes a second upright frame 5 fixedly connected to the base 1. The second upright frame 5 is provided with a third linear screw module 36. The moving end of the third linear screw module 36 is fixedly provided with a lifting frame 9. The lifting frame 9 is provided with a second linear screw module 34. The moving end of the second linear screw module 34 is fixedly provided with a moving seat 39. A rack 10 is slidably provided on the moving seat 39. Two sleeves 31 are respectively fixedly connected to the ends of the two racks 10. A gear 38 is rotatably provided on the moving seat 39. The gear 38 meshes with the rack 10. A third motor 37 for driving the gear 38 to rotate is fixedly provided on the moving seat 39.

[0046] like Figure 9 and Figure 10 As shown, a motor 33 for driving the cloth roller 32 to rotate is fixed on the sleeve 31. A scraper 35 is slidably inserted into the side wall of the sleeve 31. A spring 40 is fixedly connected to one end of the scraper 35, and the other end of the spring 40 is fixedly connected to the side wall of the sleeve 31. The scraper 35 is in contact with the surface of the anti-overflow cloth 30.

[0047] Specifically, in the above embodiments, although the agitation of multiple toothed plates 29 can be used to break the arching and agglomeration structure of glitter powder, the agitation will also cause the glitter powder to be lifted up. As glitter powder is continuously added, the top glitter powder gets closer and closer to the container opening, and the lifted glitter powder is more likely to overflow through the edge of the container opening, thus affecting the normal collection of glitter powder.

[0048] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: First, based on the height of the container, the height of the lifting frames 9 on both sides is simultaneously adjusted using the linear screw modules 36 on both sides, so that the bottom edge of the spill cover 30 is lower than the top of the container. Initially, the unwound portion of the spill cover 30 is taut, and the spill cover 30 is located on the side closest to the support 3. After the height of the spill cover 30 is adjusted, the movable seats 39 on both sides are simultaneously driven by the linear screw modules 34 on both sides, causing the spill cover 30 to move towards the upright frame 4. During this movement, the central area of ​​the spill cover 30 is intercepted by the container edge. Simultaneously, the motor 33 drives the cloth roller 32 to rotate, unwinding the spill cover 30 and bending the unwound portion to surround the outer wall of the container. When the two sleeves 31 reach the other edge of the container from one side edge, the motor 37 drives the gear 38 to rotate, causing the rack 10 to move laterally on the movable seat 39, bringing the two sleeves 31 closer together until they are in contact.

[0049] At this point, the anti-overflow cloth 30 surrounds the container opening and adheres tightly to the outer wall of the container under the winding of the cloth roller 32. This creates a barrier higher than the container opening formed by the unwound portion of the anti-overflow cloth 30. Even if the toothed plate 29 stirs up the glitter powder, the powder will be blocked by the barrier formed by the anti-overflow cloth 30 and fall back into the container, effectively preventing the glitter powder from overflowing from the container opening edge, reducing material waste, and ensuring the continuity of the collection process and the accuracy of the collection volume. Furthermore, because the anti-overflow cloth 30 can be adjusted in height according to the container height and adheres tightly to the outer wall of the container through the winding and unwinding of the cloth roller 32, it can be adapted to collection containers of different heights and diameters, further improving the versatility and reliability of the equipment.

[0050] Furthermore, although the spill containment cloth 30 can block glitter powder, due to its interception effect, some glitter powder that falls back onto its surface tends to accumulate in the angled area between the spill containment cloth 30 and the inner wall of the container, especially near the bottom edge of the spill containment cloth 30 close to the container opening. As the collection process continues, this glitter powder gradually accumulates, unable to pass over the spill containment cloth 30 or fall back into the container. When the container is subsequently removed, this glitter powder will scatter outside the container due to the loss of support from the spill containment cloth 30, causing material loss and environmental pollution. Therefore, to avoid this problem, after the feeding operation is completed and before the container is removed from the feeding tank 2, the motors 33 on both sides are activated. This causes one side's cloth roller 32 to unwind the spill containment cloth 30, while the other side rewinds it, allowing the spill containment cloth 30 to move along the outer wall of the container. During the movement of the overflow prevention cloth 30, the glitter powder accumulated in the area between the overflow prevention cloth 30 and the inner wall of the container will move along with it due to the friction of the overflow prevention cloth 30, thereby dispersing the accumulated glitter powder and making it easier to fall back into the container. This prevents the glitter powder accumulated at the edge of the container opening from falling outside the container due to the loss of the support of the overflow prevention cloth 30 when the container is moved, further avoiding material loss and environmental pollution.

[0051] Furthermore, since the scraper 35 presses against the contact surface between the anti-overflow cloth 30 and the glitter powder under the action of the spring 40, the scraper 35 will scrape the surface of the anti-overflow cloth 30 before the anti-overflow cloth 30 is put into the sleeve 31, causing the glitter powder attached to the surface of the anti-overflow cloth 30 to fall off, so that the glitter powder can fall back into the container when the anti-overflow cloth 30 enters the sleeve 31, thereby further recycling materials, reducing waste, and also avoiding the smoothness of subsequent opening and closing due to the glitter powder attached to the surface of the anti-overflow cloth 30.
