Description

Technical Field

[0001] This utility model belongs to the field of paper product processing technology, and in particular relates to a scrap collection device for paper product processing. Background Technology

[0002] The processing of paper products generates a large amount of scrap material. If this scrap material is not removed from the processing machinery, it will affect the continuous operation of the equipment and may even damage the equipment.

[0003] In the paper processing industry, scrap collection is a crucial production step. With the continuous expansion of paper production scale and the increasing complexity of processing techniques, the problem of scrap collection and disposal has become increasingly prominent. Paper products are typically thin and lightweight, and highly volatile, especially during cutting, trimming, and prototyping processes, which generate a large number of small scraps. If these scraps are not collected promptly and effectively, they often scatter throughout the workplace, even exceeding the designated collection points, causing environmental pollution and increasing the difficulty of workshop cleanup.

[0004] Furthermore, due to the high surface absorbency of paper products, the scattered scraps are easily affected by dust, oil, or other pollutants in the air. Once these scraps are contaminated, they cannot be reused as raw materials, resulting in resource waste. Traditional scrap collection devices often fail to effectively address the problems caused by the lightweight and easily dispersed nature of paper products, leading to incomplete collection of scraps within the collection box. Some scraps may even be blown away by the wind or fall to other parts of the workshop due to poor equipment design.

[0005] Currently, most paper product processing enterprises still rely on manual cleaning or basic collection devices to handle these scraps. Although this can reduce the loss of scraps to some extent, the overall efficiency is low and it is easily affected by environmental factors, failing to achieve the ideal collection effect. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a paper product processing scrap collection device that offers a more efficient and stable collection method to address the lightweight and volatile characteristics of paper products.

[0007] In view of this, the present invention provides a scrap collection device for paper product processing, comprising:

[0008] The frame is equipped with a conveying mechanism for conveying scrap materials;

[0009] The bottom frame is located at the front of the rack;

[0010] The collection box is located at the top of the bottom frame, below the front side of the conveying mechanism;

[0011] A pushing mechanism, located on the left and right sides of the collection box, is used to push the fallen scraps into the collection box.

[0012] The toggle mechanism includes:

[0013] The grooves are located on the left and right sides of the collection box;

[0014] Support plates are installed at the front and rear ends of the left and right sides of the collection frame;

[0015] The pivot is rotatably positioned between two support plates on the same side.

[0016] Elastic paddles are set on the rotating shaft. There are multiple elastic paddles, which are evenly spaced along the circumferential direction of the rotating shaft. The elastic paddles are located in the groove.

[0017] The two elastic levers rotate in opposite directions to generate wind, which blows the scraps into the collection box. When the scraps fall out of the collection box, the elastic levers push the scraps back into the collection box. The elastic levers have a certain elasticity, which makes the scraps less likely to be damaged.

[0018] In the above technical solution, the elastic paddle is further bent.

[0019] In any of the above technical solutions, the conveying mechanism further includes:

[0020] The drive shaft is rotatably mounted on the left and right sides of the frame;

[0021] The roller is mounted on the drive shaft;

[0022] The conveyor belt is positioned between two rollers;

[0023] Motor 2 is mounted on the frame, and its output shaft is connected to the drive shaft.

[0024] A pulley is mounted on the drive shaft;

[0025] A flat belt is wound between two pulleys;

[0026] The rotating rod is rotatably mounted on the upper front side of the frame.

[0027] The extrusion roller is mounted on the rotating rod and is located above the conveyor belt.

[0028] In any of the above technical solutions, a further step is to provide an ejection mechanism on the bottom frame for ejecting scrap materials from the collection box;

[0029] The issuing organizations include:

[0030] The cylinder is located inside the bottom frame;

[0031] The push plate is mounted on the cylinder piston rod and is located on the bottom frame.

[0032] Guide grooves are formed around the inside of the collection box;

[0033] The slide plate is slidably positioned within the guide groove;

[0034] The connecting plate is located between the bottom of the four skateboards, inside the collection box, and above the push plate.

[0035] In any of the above technical solutions, the push plate and the connecting plate are further connected by a movable connecting mechanism. The movable connecting mechanism includes a socket and a rod. The socket is located around the top of the push plate, and the rod is located around the bottom of the connecting plate. The rod is positioned opposite to the socket and is inserted into the socket.

[0036] In any of the above technical solutions, a further provision includes a capping mechanism, which includes:

[0037] Fixed blocks are installed at the top front left and right ends of the collection box;

[0038] The door hinge is rotatably mounted on a fixed block.

[0039] Rotating plates are installed at both ends of the door hinge;

[0040] A cover plate is placed between the rotating plates, and the cover plate covers the feed inlet of the collection frame;

[0041] A handle is located on the cover plate;

[0042] A latch, located between the cover plate and the collection frame, is used to lock the cover plate in place.

[0043] The beneficial effects of this utility model are:

[0044] 1. The scrap material is conveyed to the collection box by the conveying mechanism. The elastic lever generates wind force and works in conjunction with the lever mechanism to effectively push the falling scrap material back to the collection box. The elastic lever makes the wind force not only able to carry the scrap material into the collection box, but also to collect it effectively without damaging the scrap material. This solves the problem that traditional collection devices cannot effectively deal with the lightness and scattering of paper product scrap material. It can better improve production efficiency, reduce resource waste, and maintain the cleanliness of the production environment.

[0045] 2. The motor drives the pulley and drive shaft to rotate, which in turn drives the rollers and conveyor belt to start running, transporting the scraps from the processing area to the collection area. The scraps on the conveyor belt are pressed by the extrusion rollers to prevent them from being loose or stuck on the conveyor belt. In this way, the scraps generated during the processing are effectively transported from the processing area to the designated location, effectively reducing the scraps left in the paper product processing, improving production efficiency and reducing the burden of manual collection.

[0046] 3. Through the operation of the cylinder, the push plate is pushed horizontally along the inside of the collection frame. The push plate drives the connecting plate to move upward along the collection frame. The connecting plate pushes the scraps in the collection frame out from the top. The scraps are smoothly pushed out of the collection frame, avoiding accumulation and piling up, and will not cause blockage due to excessive scraps.

[0047] 4. The design of the insertion hole and the insertion rod allows the push plate and the connecting plate to be connected and disconnected by insertion and removal. This simple disassembly method reduces downtime and improves the maintenance efficiency of the equipment. It provides a flexible and stable connection between the push plate and the connecting plate, which can ensure that the push plate works stably and effectively when pushing scrap materials.

[0048] 5. Secure the cover plate to the collection frame using the latches. At this point, start the cylinder. The cylinder drives the push plate to move upward, which in turn moves the connecting plate upward. The connecting plate pushes the scraps collected in the collection frame, compressing the scraps inside the collection frame. The compressed scraps are less likely to drift, saving space.

[0057] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0058] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0059] Example 1:

[0060] like Figures 1-3 As shown, this embodiment provides a scrap collection device for paper product processing, including:

[0061] The frame 1 is equipped with a conveying mechanism 5 for conveying scrap materials;

[0062] Base frame 2 is located on the front side of frame 1;

[0063] The collection box 3 is located at the top of the bottom frame 2, below the front side of the conveying mechanism 5;

[0064] The agitating mechanism 4 is located on the left and right sides of the collection box 3 and is used to agitate the fallen scraps into the collection box 3.

[0065] The toggle mechanism 4 includes:

[0066] Grooves 41 are located on the left and right sides of the collection frame 3;

[0067] Support plates 42 are set at the front and rear ends of the left and right sides of the collection frame 3;

[0068] A rotating shaft 43 is rotatably positioned between two support plates 42 on the same side.

[0069] Elastic paddle 44 is disposed on the rotating shaft 43. There are multiple elastic paddles 44, which are evenly spaced along the circumferential direction of the rotating shaft 43. The elastic paddles 44 are located in the groove 41.

[0070] Motor 45, the output shaft of which is connected to rotating shaft 43;

[0071] The elastic paddles 44 on both sides rotate in opposite directions to generate wind, which blows the scraps into the collection frame 3. When the scraps fall out of the collection frame 3, the elastic paddles 44 push the scraps back into the collection frame 3. The elastic paddles 44 have a certain elasticity, which makes the scraps less likely to be damaged.

[0072] In this technical solution, during the paper product processing, the scraps generated are conveyed to the front end of the collection device via the conveying mechanism 5. Due to the lightweight nature of paper products, the scraps may scatter during the conveying process. During this scattering, they are easily contaminated by dust and dirt in the environment, affecting their reuse.

[0073] The scrap material is conveyed to the collection frame 3 area by the conveying mechanism 5. At this time, some scrap material may fall from outside the collection frame 3 due to airflow or inertia. The motor 45 drives the rotating shaft 43 to rotate, causing the rotating shaft 43 to rotate in opposite directions, generating a certain amount of wind force. These elastic levers 44 drive the airflow, thus guiding the scattered scrap material back into the collection frame 3. The elastic levers 44 are distributed on the rotating shaft 43 and have a certain degree of elasticity. When the scrap material approaches, the elastic levers 44 will contact the scrap material at an appropriate angle, ensuring that the scrap material will not be subjected to excessive impact force when it is moved, thereby avoiding damage. Under the interaction of the elastic levers 44 on both sides, the scrap material is effectively returned to the collection frame 3.

[0074] The elastic lever 44 generates wind force through its elasticity and also pushes the scrap material through mechanical rotation. When the scrap material drifts outside the collection frame 3, the elastic lever 44 pushes it into the collection frame 3 through the generated wind force and physical force, ensuring effective collection. Guided by the wind, the scrap material is effectively concentrated in the collection frame 3, preventing it from scattering in the workshop. Simultaneously, due to the flexible design of the elastic lever 44, the scrap material is not damaged when moved, maintaining a good shape suitable for subsequent reprocessing or reuse. This solves the problem of traditional collection devices being unable to effectively handle the lightness and scattering of paper product scraps, improving production efficiency, reducing resource waste, and maintaining a clean production environment.

[0075] like Figures 1-3 As shown, in this embodiment, the optimized elastic paddle 44 is bent.

[0076] In this technical solution, the airflow effect generated by the bent elastic lever 44 during rotation is more advantageous than that of a straight lever. The bent design can more effectively generate directional airflow, guiding the falling scraps more accurately towards the collection frame 3, thereby improving the collection efficiency of scraps. When the bent elastic lever 44 comes into contact with the scraps, it can act on the scraps at a more suitable angle, enhancing the agitation effect. Because the bent shape matches the movement trajectory of the scraps, it can more effectively push the scraps into the collection frame 3, and is less likely to cause the scraps to scatter or deviate from the collection frame 3. The bent elastic lever 44 can provide a gentler contact force in terms of elasticity and shape, reducing the impact force generated when colliding with the scraps, thereby preventing damage to the paper scraps when agitated. Paper scraps are usually fragile, and the bent design helps to reduce the contact force, ensuring the integrity and reusability of the scraps during the collection process. Due to its unique shape, the bent elastic lever 44 increases the contact area between the side wall of the collection frame 3 and the rotating shaft 43, thereby increasing stability and ensuring the accuracy and reliability of the lever during rotation, and preventing deformation or loosening from affecting the normal operation of the equipment.

[0077] Example 2:

[0078] This embodiment provides a scrap collection device for paper product processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0079] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the optimized conveying mechanism 5 includes:

[0080] The drive shaft 51 is rotatably mounted on the left and right sides of the frame 1;

[0081] Roller 52 is mounted on drive shaft 51;

[0082] Conveyor belt 53 is positioned between two rollers 52;

[0083] Motor 2 54 is mounted on frame 1, and the output shaft of motor 2 54 is connected to transmission shaft 51;

[0084] Pulley 55 is mounted on drive shaft 51;

[0085] A flat belt 56 is wound between two pulleys 55;

[0086] Rotary rod 57 is rotatably mounted on the upper front side of frame 1;

[0087] An extrusion roller 58 is mounted on a rotating rod 57 and is positioned above the conveyor belt 53.

[0088] In this technical solution, motor 54 starts working, driving pulley 55 and drive shaft 51 to rotate, which in turn drives roller 52 and conveyor belt 53 to start operating. After roller 52 on drive shaft 51 rotates, it drives the conveyor belt 53 mounted on it to run, transporting the scraps generated during paper product processing from the processing area to the collection area. Above the conveyor belt 53, an extrusion roller 58 is installed on a rotating rod 57. The rotating rod 57 drives the extrusion roller 58 to move, and the extrusion roller 58 compacts the scraps on the conveyor belt 53, preventing the scraps from becoming loose or stuck on the conveyor belt 53. This action ensures that the scraps are efficiently transported and compacted for subsequent processing. Through the linkage of the above-mentioned transmission and extrusion mechanisms, the device can continuously collect and transport scraps, realizing efficient and automated production line operation. Operators can adjust the tension of the flat belt 56 between pulleys 55 or the running speed of motor 2 54 as needed to control the movement speed and conveying efficiency of conveyor belt 53. This enables the scraps generated during processing to be effectively transported from the processing area to the designated location, effectively reducing the scraps left over during paper product processing, improving production efficiency and reducing the burden of manual collection.

[0089] Example 3:

[0090] This embodiment provides a scrap collection device for paper product processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0091] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the bottom frame 2 is optimized to provide an ejection mechanism 6 for ejecting scrap materials from the collection box 3;

[0092] The six launching organizations include:

[0093] Cylinder 61 is located inside the bottom frame 2;

[0094] Push plate 62 is mounted on piston rod of cylinder 61 and is located on bottom frame 2;

[0095] Guide grooves 63 are formed around the inside of the collection frame 3;

[0096] The slide plate 64 is slidably disposed within the guide groove 63;

[0097] A connecting plate 65 is positioned between the bottoms of the four slide plates 64. The connecting plate 65 is located inside the collection box 3 and above the push plate 62.

[0098] In this technical solution, when it is necessary to eject scrap material from the collection frame 3, cylinder 61 starts working. The piston rod of cylinder 61 is connected to push plate 62. Through the operation of cylinder 61, push plate 62 is pushed horizontally along the inside of collection frame 3. Push plate 62 drives connecting plate 65 to move upward along collection frame 3. Connecting plate 65 ejects scrap material from the top of collection frame 3. The movement of connecting plate 65 is guided by slide plate 64 and guide groove 63. The function of slide plate 64 is to ensure that connecting plate 65 can slide smoothly within the fixed track, avoiding uneven pushing or jamming due to deviation. This allows connecting plate 65 to smoothly eject scrap material from collection frame 3. Connecting plate 65 pushes scrap material out through the outlet of collection frame 3. Scrap material is smoothly ejected from outside collection frame 3, avoiding accumulation and buildup. Through periodic or continuous ejection operations, the entire collection system can maintain normal operation and will not be blocked due to excessive scrap material. After each ejection operation, cylinder 61 resets push plate 62 through the reverse movement of piston rod, preparing for the next ejection action.

[0099] like Figure 5 As shown, in this embodiment, the push plate 62 and the connecting plate 65 are connected by a movable connecting mechanism 7. The movable connecting mechanism 7 includes a socket 71 and a rod 72. The socket 71 is disposed around the top of the push plate 62, and the rod 72 is disposed around the bottom of the connecting plate 65. The rod 72 is disposed opposite to the socket 71 and is inserted into the socket 71.

[0100] In this technical solution, the design of the insertion hole 71 and the insertion rod 72 allows the push plate 62 and the connecting plate 65 to be connected and disconnected by insertion and removal. This movable connection method effectively allows for the disassembly of the push plate 62 and the connecting plate 65, while ensuring a tight fit during operation, avoiding the limitations of overly rigid fixing methods. Because the insertion rod 72 is inserted into the insertion hole 71, a stable connection is maintained between the connecting plate 65 and the push plate 62, ensuring that the push plate 62 will not detach or misalign due to vibration or movement when pushing scrap materials. The precise fit between the insertion rod 72 and the insertion hole 71 ensures that the push plate 62 exerts a uniform and stable pushing force when pushing out scrap materials. Through the movable connection mechanism 7, the connection between the push plate 62 and the connecting plate 65 is simpler, allowing for quick disassembly and installation during maintenance or component replacement without the need for complex tools or processes. The structure of the insertion rod 72 and the insertion hole 71 allows operators to easily handle the connection parts, improving the maintainability of the equipment.

[0101] When maintenance is required on the push plate 62, connecting plate 65, or connecting mechanism, the operator can easily pull the insert rod 72 out of the socket 71 to quickly disassemble the connecting part. This simple disassembly method reduces downtime and improves equipment maintenance efficiency. This provides a flexible and robust connection between the push plate 62 and the connecting plate 65, ensuring that the push plate 62 works stably and effectively when pushing scrap materials.

[0102] Example 4:

[0103] This embodiment provides a scrap collection device for paper product processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0104] like Figure 6 and Figure 7 As shown, in this embodiment, the optimization further includes a capping mechanism 8, which includes:

[0105] Fixing block 81 is set at the top front left and right ends of the collection box 3;

[0106] The door hinge 82 is rotatably mounted on the fixed block 81;

[0107] Rotating plates 83 are located at both ends of the door hinge 82;

[0108] Cover plate 84 is disposed between the rotating plates 83, and cover plate 84 covers the feed inlet of collection frame 3;

[0109] Handle 85 is provided on cover plate 84;

[0110] The latch 86 is located between the cover plate 84 and the collection frame 3 and is used to lock the cover plate 84.

[0111] In this technical solution, when workers need to collect scraps from paper products during processing, they pull handle 85, causing cover 84 to open the feed inlet of collection frame 3 via rotation of turntable 83. Since hinge 82 is fixed to fixed block 81, turntable 83 can rotate smoothly with the support of hinge 82, allowing cover 84 to open smoothly from the top of collection frame 3, facilitating the collection of scraps. During paper product processing, conveying mechanism 5 feeds scraps into collection frame 3, ensuring all scraps are effectively collected. Once the scraps are collected, workers can grasp handle 85 again to rotate and close cover 84. Cover 84, driven by turntable 83, closes the feed inlet, effectively sealing the scraps inside collection frame 3. After closing the cover plate 84, the worker needs to fix the cover plate 84 to the collection frame 3 using the latch 86. The latch 86 ensures that the cover plate 84 is firmly attached to the collection frame 3 through physical locking. At this time, the cylinder 61 is activated, which drives the push plate 62 to move upward. The push plate 62 drives the connecting plate 65 to move upward through the cooperation of the insertion hole 71 and the insertion rod 72. The connecting plate 65 drives the slide plate 64 to slide upward in the guide groove 63. The connecting plate 65 pushes the scrap material collected in the collection frame 3, which is locked by the cover plate 84, so that the scrap material in the collection frame 3 is compressed and tightened. The scrap material is less likely to drift and saves space. Once the scrap material is compressed to a suitable state, cylinder 61 is closed, latch 86 is opened, handle 85 is pulled to open cover 84, cylinder 61 is restarted to push out the compressed scrap material. This effectively seals and protects the scrap material collection frame 3 during the paper product processing, preventing the scrap material in the collection frame 3 from being contaminated by the outside. The latch 86 ensures that cover 84 is firmly connected to collection frame 3 by physical locking, so as to compress the scrap material in collection frame 3. The compressed scrap material is less likely to drift and saves space.

[0112] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
