Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper product processing technology, specifically to an automatic collection device for paper product scraps. Background Technology
[0002] Paper product processing refers to the process of transforming paper or paperboard as raw materials into paper products with specific functions, uses and forms through a series of physical, chemical or mechanical processing techniques.
[0003] In the paper product processing and production process, the automatic collection and handling of scrap materials is crucial for ensuring production efficiency and reducing labor costs. Traditional scrap material collection devices typically use open hoppers with simple gravity-feed structures, which have several technical bottlenecks. On the one hand, the existing devices lack precise size design for the discharge holes, making it difficult to effectively separate paper products from scrap materials. This results in normal-sized paper products falling out or scrap materials remaining, requiring frequent manual cleaning. On the other hand, the collection devices have poor sealing, allowing dust to easily spill out and pollute the workshop environment. Furthermore, the collection boxes are mostly fixed installations, requiring machine shutdown and disassembly for replacement, which is cumbersome and inefficient. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automatic collection device for paper product scraps, which solves the problems mentioned in the background art.
[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:
[0006] An automatic collection device for paper product scraps includes a hopper, the bottom of which is provided with a support base;
[0007] The support base has an internal cavity containing a collection box. A support net is installed on the hopper, and the support net is welded and fixed to the hopper by four L-shaped stainless steel brackets. The support net is a paper product processing platform. A fixing plate is installed on the support net, and a motor is installed on the fixing plate. A scraper is installed at the output end of the motor and fits against the inner surface of the hopper. A collection hopper is provided at the bottom of the hopper.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, multiple collection boxes are rotatably installed inside the receiving cavity, and each collection box is provided with a wall panel. Multiple collection boxes are placed in close contact with each other through the wall panels, and adjacent collection boxes are sealed with rubber sealing strips to prevent leakage of scrap materials.
[0010] The beneficial effects of adopting the above-mentioned further solutions are:
[0011] The rotating collection box facilitates quick disassembly and replacement. Workers can easily remove a fully loaded collection box by simply rotating it around the pivot axis out of the receiving cavity opening, without the need for complicated tools or cumbersome operations, significantly improving maintenance efficiency. The wall panel fit and rubber sealing strip design form a tight sealing structure, preventing scraps from spilling out of the collection box gaps. In addition, the combination of multiple collection boxes maximizes the use of the receiving cavity space, increases the single collection capacity, and reduces the replacement frequency, making it suitable for high-volume paper product processing scenarios.
[0012] Furthermore, the motor is located on the back of the bottom end of the fixed plate, and the motor is connected to the scraper drive through a reducer.
[0013] The beneficial effects of adopting the above-mentioned further solutions are:
[0014] The rear-mounted motor design separates it from the paper processing platform, effectively preventing operators from accidentally touching the rotating parts of the motor during operation and reducing safety risks. Simultaneously, it reduces contamination of the motor by paper dust and debris during processing, extending its service life. The application of the speed reducer allows for adjustment of the scraper speed according to actual needs. This ensures the scraper cleans scraps at an appropriate speed, preventing material splashing due to excessive speed, while also increasing torque to ensure stable operation when cleaning highly adhesive scraps, improving cleaning efficiency and reliability. Furthermore, the speed reducer buffers the impact force during motor startup and operation, reducing mechanical vibration and lowering operating noise.
[0015] Furthermore, the fixing plate is provided with a protective cover on the outside of the motor.
[0016] The beneficial effects of adopting the above-mentioned further solutions are:
[0017] The protective cover provides a physical barrier for the motor, preventing dust, debris and other foreign objects generated during processing from entering the motor and preventing short circuits, jamming and other malfunctions caused by foreign objects, thus effectively improving the safety and stability of motor operation.
[0018] Furthermore, the opening width of the receiving cavity is greater than the width of the collection box, and a dustproof curtain is installed at the opening to prevent dust from entering the receiving cavity.
[0019] The beneficial effects of adopting the above-mentioned further solutions are:
[0020] The opening width is greater than the width of the collection box, providing ample space for the disassembly and installation of the collection box, enabling staff to quickly and smoothly replace the collection box and improving operational convenience; the dust curtain effectively blocks external dust and debris from entering the receiving cavity, facilitating subsequent recycling and processing.
[0021] Furthermore, the surface of the support mesh is provided with a plurality of evenly distributed dropping holes, the diameter of which is smaller than the size of normal paper products but larger than the size of paper product scraps.
[0022] The beneficial effects of adopting the above-mentioned further solutions are:
[0023] The precise aperture design enables automatic material separation. Normal-sized paper products can be stably placed on the surface of the support mesh for processing, while the scraps generated, being smaller than the aperture of the support mesh, naturally fall into the hopper under gravity, eliminating the need for manual sorting and greatly improving production efficiency.
[0024] This utility model provides an automatic collection device for paper product scraps. It has the following beneficial effects:
[0025] The discharge holes on the support mesh surface are designed to be smaller than the size of normal paper products but larger than the size of scraps, enabling automatic separation of paper products and scraps. Normal paper products remain on the support mesh surface during processing, while scraps fall directly into the lower hopper through the discharge holes, avoiding manual sorting and improving production efficiency.
[0026] The scraper rotates in close contact with the inner surface of the hopper, ensuring close contact with the inner wall of the hopper. This thoroughly sweeps the scrap material attached to the side walls or corners of the hopper into the collection hopper. The mechanical thrust of the scraper can actively guide the scrap material to move towards the collection hopper, significantly shortening the material transfer time, reducing the amount of scrap material accumulating in the hopper, and improving the collection efficiency per unit time.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:
[0037] Example 1
[0038] An automatic collection device for paper product scraps includes a hopper 5, a support base 1 at the bottom of the hopper 5, a receiving cavity 101 inside the support base 1, a collection box 6 installed in the receiving cavity 101, a support net 3 installed on the hopper 5, and the support net 3 is welded and fixed to the hopper 5 by four L-shaped stainless steel brackets. The support net 3 is a paper product processing platform. The surface of the support net 3 has multiple evenly distributed dropping holes. The diameter of the dropping holes is smaller than the size of normal paper products but larger than the size of paper product scraps. The precise hole diameter design realizes the automatic separation of materials. Normal-sized paper products can be stably placed on the surface of the support net 3 for processing, while the scraps generated, because their size is smaller than the hole diameter of the support net 3, fall naturally into the hopper 5 under the action of gravity, eliminating the need for manual sorting and greatly improving production efficiency. A fixing plate 4 is installed on the support net 3, and a motor 401 is installed on the fixing plate 4. A scraper 2 is installed at the output end of the motor 401. The scraper 2 is attached to the inner surface of the hopper 5. A collection hopper 501 is provided at the bottom of the hopper 5.
[0039] Example 2
[0040] To improve the ease of replacing the collection box and enhance its dustproof sealing effect, for example, such as Figures 1 to 4As shown, this utility model also includes: the opening width of the receiving cavity 101 is greater than the width of the collection box 6, and a dust curtain is installed at the opening to prevent dust from entering the receiving cavity 101. The opening width is greater than the width of the collection box 6, providing sufficient space for the disassembly and installation of the collection box 6, enabling workers to quickly and smoothly replace the collection box 6 and improving operational convenience; the dust curtain can effectively block external dust and debris from entering the receiving cavity 101, facilitating subsequent recycling and processing. Multiple collection boxes 6 are rotatably installed in the receiving cavity 101, and each collection box 6 is provided with a wall panel 601. Multiple collection boxes 6 are placed in close contact through the wall panel 601, with adjacent collection boxes... The collection boxes 6 are sealed with rubber sealing strips to prevent leakage of scrap materials. The rotating installation of the collection boxes 6 facilitates quick disassembly and replacement. Workers only need to rotate the collection box 6 around the rotating shaft to exit the opening of the receiving cavity 101 to easily remove the fully loaded collection box 6 without complicated tools or cumbersome operations, which significantly improves maintenance efficiency. The wall panel 601 is designed to fit with the rubber sealing strip to form a tight sealing structure, which can prevent scrap materials from overflowing from the gaps in the collection box 6. In addition, the combination of multiple collection boxes 6 maximizes the use of the space in the receiving cavity 101, increases the single collection capacity, and reduces the replacement frequency, which is suitable for high-volume paper product processing scenarios.
[0041] Example 3
[0042] To optimize motor protection and transmission stability, for example, such as Figures 1 to 4 As shown, this utility model also includes: a motor 401 located on the back of the bottom end of the fixed plate 4, and the motor 401 is connected to the scraper 2 via a reducer. The rear-mounted design of the motor 401 separates it from the paper product processing platform, effectively preventing operators from accidentally touching the rotating parts of the motor 401 during operation and reducing safety risks; at the same time, it reduces the contamination of the motor 401 by paper dust and debris during processing and extends the service life of the motor 401. The application of the speed reducer allows for adjustment of the scraper 2's rotational speed according to actual needs. This ensures that the scraper 2 cleans scraps at a suitable speed, preventing material splashing due to excessive speed. Furthermore, by increasing torque, it ensures stable operation of the scraper 2 when cleaning highly adhesive scraps, improving cleaning efficiency and reliability. In addition, the speed reducer can buffer the impact force during motor 401 startup and operation, reducing mechanical vibration and lowering operating noise. The fixed plate 4, located outside the motor 401, is equipped with a protective cover 402. This cover provides a physical protective barrier for the motor 401, preventing dust, debris, and other foreign matter generated during processing from entering the motor 401. This prevents short circuits, jamming, and other malfunctions caused by foreign object intrusion, effectively improving the safety and stability of motor 401 operation.
[0043] Working principle:
[0044] The support mesh 3 serves as a paper product processing platform. The diameter of the discharge holes distributed on its surface is specially designed to be smaller than the normal size of paper products but larger than the size of paper scraps. During the paper product processing, normal paper products can be placed stably on the surface of the support mesh 3 for further processing, while the generated scraps, because their size conforms to the discharge hole specifications, pass directly through the discharge holes under the action of gravity and fall into the material bin 5 below, thus completing the automatic separation of paper products and scraps.
[0045] After the motor 401, mounted on the fixed plate 4, starts, it drives the scraper 2 to rotate via a reducer. Because the scraper 2 is in close contact with the inner surface of the hopper 5, it actively sweeps away scrap materials adhering to the side walls, corners, and bottom of the hopper 5 during rotation, using mechanical thrust to quickly guide the scrap materials to the collection hopper 501 at the bottom of the hopper 5. This process effectively avoids the accumulation and retention of scrap materials in the hopper 5, achieving efficient cleaning.
[0046] The scrap material swept and pushed to the collection hopper 501 by the scraper 2 slides down the collection hopper 501 under the action of gravity and finally falls into the collection box 6 in the receiving cavity 101 of the support base 1. Multiple collection boxes 6 are placed together by the wall panel 601, and adjacent collection boxes 6 are sealed by rubber sealing strips to prevent the scrap material from leaking out. At the same time, the opening width of the receiving cavity 101 is larger than the width of the collection box 6, and a dust curtain is installed at the opening, which not only prevents dust from entering, but also makes it easy for workers to directly pull out the collection box 6 from the opening for cleaning or replacement after it is full, ensuring the sealing and convenience of the collection process.
