Abstract

This invention discloses an edge cleaning device for paper product processing, relating to the field of paper product processing. It includes a support frame with a vertically oriented groove in the middle, within which a fixed arm and an electric waste cleaner are slidably mounted. This invention utilizes a right-angle geared motor to drive a screw and a sliding rod, enabling the fixed arm and the electric waste cleaner to move downwards and separate synchronously.

Description

Technical Field

[0001] This invention relates to the field of paper product processing, and more specifically to an edge cleaning device for paper product processing. Background Technology

[0002] Paper products are widely used in various fields such as food packaging, pharmaceutical packaging, cosmetic packaging, and logistics transportation cartons due to their advantages of being lightweight, environmentally friendly, and low-cost. Common processed products include corrugated boxes, color-printed packaging boxes, shopping bags, hang tags, and cards. In the paper product processing flow, die-cutting is one of the key processes. After the paper is cut into the preset product shape by the die-cutting machine, a large amount of waste material such as outer edges and inner hole waste will remain. Cleaning these waste materials directly affects the product forming quality, subsequent processing efficiency, and workshop production environment.

[0003] Currently, in the paper product processing industry, the cleaning of edge materials after die-cutting mainly relies on waste removal equipment. Existing waste removal equipment includes fully automatic waste removal machines, tabletop pneumatic waste removal machines, and handheld pneumatic waste removal machines. Among them, fully automatic waste removal machines can realize integrated operation of feeding, waste removal, and palletizing, with high efficiency and low dependence on manual labor, and are suitable for large-scale standardized production. Tabletop pneumatic waste removal machines reduce the intensity of hand operation through a fixed working platform and pneumatic drive, and are suitable for small and medium batch production. Handheld waste removal machines have become commonly used equipment in small processing plants, temporary cleaning operations, and irregular part processing due to their advantages such as compact structure, flexible movement, and low procurement cost. They use a motor to drive a toothed chain to achieve the hooking and separation of edge materials.

[0004] However, existing handheld waste cleaning machines require operators to hold the device and align it with the edge material throughout the entire process, while also manually pressing down the stacked paper products to prevent displacement. During operation, operators need to constantly bend over and raise their hands, which can easily lead to occupational injuries such as lumbar muscle strain and neck and shoulder pain over a long period of time. Therefore, an edge material cleaning device for paper product processing is proposed. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an edge cleaning device for paper product processing to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a paper product processing edge cleaning device, comprising a support frame, wherein a vertical groove is provided in the middle of the support frame, and a fixed arm and an electric waste cleaner are slidably installed in the groove, wherein sliders are fixedly installed at the ends of the fixed arm and the electric waste cleaner, and slide rods and screws are fixedly installed on both sides of the groove, wherein one side of the fixed arm is slidably installed on the slide rod via the slider, and both sides of the electric waste cleaner are slidably installed on the screw and the slide rod via the slider, for driving the electric waste cleaner and the fixed arm to move up and down, and magnetic blocks are correspondingly installed at the bottom of the fixed arm and the top of the electric waste cleaner for magnetic connection between the fixed arm and the electric waste cleaner;

[0007] A rotating arm is rotatably mounted on the end of the fixed arm away from the electric waste cleaner, and a pressure block is fixedly mounted on the end of the rotating arm for pressing and fixing the stacked paper products. A connecting plate is fixedly connected to the top of the support frame, and the rotating arm cooperates with the connecting plate for storing the pressure block. A pulling mechanism is provided between the fixed arm and the electric waste cleaner to ensure the pressure of the pressure block on the paper products.

[0008] By adopting the above technical solution, the precise switching between the electric waste removal machine and the fixed arm can be achieved, which not only ensures the stability of the waste removal process, but also eliminates the need for manual hand-holding or pressing. Combined with the traction mechanism, the pressure of the block is continuously maintained, effectively solving the pain points of manual bending operation and multi-person collaboration, and reducing labor intensity and occupational injury risks.

[0009] Furthermore, the pulling mechanism includes an automatic reel, a steel wire rope, and a fixing block. The two ends of the steel wire rope are fixedly connected to the automatic reel and the fixing block, respectively. The automatic reel is rotatably mounted on the inner wall of the rotating arm, and a coil spring is provided inside the automatic reel for winding the steel wire rope. The fixing block is fixedly mounted on the top of the electric waste cleaner, and when the fixing arm and the electric waste cleaner are in a magnetically connected state, the fixing block is fitted into the bottom of the fixing arm.

[0010] By adopting the above technical solution, continuous traction can be achieved without an additional power source. The structure is simple and highly stable. The pre-tension characteristics of the coil spring can automatically adapt to the relative movement of the components, always generating tension on the rotating arm, ensuring that the pressure block provides stable pressure to the paper products.

[0011] Furthermore, the bottom of the fixed arm and the rotating arm are respectively provided with wire-threading grooves for the wire rope to be hidden and installed at the bottom of the fixed arm and the rotating arm. Two sets of guide wheels are rotatably installed on the inner wall of the wire-threading groove, and are respectively located at the bottom of the fixed arm and the rotating arm and installed corresponding to the wire rope, so as to ensure smooth winding of the wire rope.

[0012] By adopting the above technical solution, the two sets of guide wheels are precisely matched to the movement trajectory of the wire rope. The rolling friction greatly reduces resistance and wear, extends the service life of the wire rope, and ensures that the wire rope winding and releasing process is smooth and without jamming.

[0013] Furthermore, a right-angle geared motor is provided on one side of the lower end of the support frame to drive the screw, and a control box is fixedly installed on the other side to supply power and control the right-angle geared motor. A base is fixedly installed at the bottom of the support frame, and a handle is fixedly installed in the middle of the support frame to push the support frame. Multiple sets of universal wheels are fixedly installed at the bottom of the base to move the support frame, and the universal wheels are equipped with a braking system.

[0014] By adopting the above technical solutions, the overall structure is compact and the functions of each component work together, which not only reduces the difficulty of equipment operation, but also improves the ease of movement and operational safety, meeting the actual production needs of small and medium-sized processing plants.

[0015] Furthermore, a rotating shaft is fixedly installed at the end of the rotating arm adjacent to the fixed arm, and a gear is fixedly installed at the end of the rotating shaft near the connecting plate. A rack is fixedly installed on the side of the connecting plate near the rotating arm, and the rack and gear work together to rotate and store the rotating arm as the fixed arm rises.

[0016] By adopting the above technical solution, the automatic unfolding and retraction of the rotating arm can be achieved without an additional power source, completely replacing manual folding operations, reducing labor intensity, and ensuring the durability and low maintenance cost of mechanical parts, thus greatly improving the continuity of operations.

[0017] Furthermore, a connecting block is fixedly connected to the top of the support frame, and the top of the connecting block is designed with an inclined surface to provide support for the rotating arm when the rotating arm is in the retracted state.

[0018] By adopting the above technical solution, reliable positioning of the rotating arm can be achieved without additional locking devices. The structure is simple and compact, with no additional maintenance costs. The supporting force is transmitted along the direction of force, which not only protects the core transmission components but also improves the overall stability and durability of the equipment, perfectly matching the function of automatic retraction of the rotating arm.

[0019] Furthermore, a telescopic column is fixedly installed on the top of the pressure block, and a spring is fixedly installed inside the telescopic column, which generates elastic pressure on the pressure block when the rotating arm presses down with the fixed arm.

[0020] By adopting the above technical solution, elastic pressure output can be achieved without an additional power source. The structure is simple and highly reliable, ensuring the stability of paper products during the waste removal process. At the same time, the operation process is simplified, eliminating the need for manual pressing of paper products and reducing labor intensity.

[0021] In summary, the present invention has the following main beneficial effects:

[0022] This invention utilizes a right-angle geared motor to drive a screw and a slide bar, enabling the fixed arm and the electric waste removal machine to move down and separate synchronously. The pressure block is provided with elastic pressure by the spring inside the telescopic column, and with the continuous traction of the pulling mechanism, stacked paper products can be flexibly fixed without manual intervention, avoiding product damage and displacement. When the electric waste removal machine moves down independently to remove waste, the pressure block is kept in a pressed state by the pulling mechanism between the rotating arm and the electric waste removal machine, ensuring waste removal accuracy. The entire edge cleaning process does not require hand-held equipment, significantly reducing the risk of occupational injuries such as lumbar muscle strain and shoulder and neck pain for operators. At the same time, the equipment can move flexibly through casters and handles, the rotating arm automatically unfolds and retracts with the help of a gear and rack mechanism, and the wire groove and guide wheel ensure smooth operation of the pulling mechanism. A single person can complete the equipment positioning, operation start-up and material unloading process, reducing labor costs and internal friction in collaboration. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of the present invention will now be described.

[0035] A paper product processing edge cleaning device, such as Figure 1-9 As shown, the device includes a support frame 1, with a vertically formed groove 16 in the middle. A fixed arm 21 and an electric waste cleaner 3 are slidably mounted in the groove 16. Slider blocks 32 are fixedly mounted at the ends of both the fixed arm 21 and the electric waste cleaner 3. Slider rods 19 and screws 18 are fixedly mounted on both sides of the groove 16. One side of the fixed arm 21 is slidably mounted on the slide rod 19 via the slider 32, and both sides of the electric waste cleaner 3 are slidably mounted on the screws 18 and slide rods 19 via the sliders 32, for driving the electric waste cleaner 3 and the fixed arm 21. 1. When the right-angle reduction motor 17 drives the screw 18 to rotate, the electric waste cleaner 3 moves vertically along the screw 18 and slide bar 19 via the sliders 32 on both sides. Magnetic blocks 33 are installed at the bottom of the fixed arm 21 and the top of the electric waste cleaner 3 respectively, for magnetic connection between the fixed arm 21 and the electric waste cleaner 3. The magnetic blocks 33 can realize the linkage or separation between the fixed arm 21 and the electric waste cleaner 3. When linked, they move down synchronously to complete the pressing and positioning. After separation, the fixed arm 21 remains stationary and the electric waste cleaner 3 can move down independently to perform the waste cleaning action.

[0036] A rotating arm 22 is rotatably mounted on the end of the fixed arm 21 away from the electric waste cleaner 3, and a pressure block 2 is fixedly mounted on the end of the rotating arm 22 for pressing and fixing the stacked paper products. During the downward movement of the fixed arm 21, the rotating arm 22 can rotate outward to unfold, so that the pressure block 2 is accurately aligned with the top of the stacked paper products and applies pressure. When the fixed arm 21 moves upward, the rotating arm 22 can rotate inward to retract. A connecting plate 14 is fixedly connected to the top of the support frame 1, and the rotating arm 22 cooperates with the connecting plate 14 to store the pressure block 2. The rotating arm 22 and the connecting plate 14 are connected by gear 231 and rack 141 to realize the automatic storage of the fixed arm 21 by moving upward, without the need for manual folding. A traction mechanism is set between the fixed arm 21 and the electric waste cleaner 3 to ensure the pressure of the pressure block 2 on the paper products. When the electric waste cleaner 3 is separated from the fixed arm 21, the traction mechanism pulls the rotating arm 22 with continuous tension to prevent the pressure block 2 from loosening and to ensure that the paper products do not shift during the waste removal process.

[0037] Please see Figure 1-9 The pulling mechanism includes an automatic reel 28, a steel wire rope 25, and a fixing block 31. The two ends of the steel wire rope 25 are fixedly connected to the automatic reel 28 and the fixing block 31, respectively. The steel wire rope 25 is made of a highly wear-resistant material to ensure it is not easily broken during long-term pulling, and its length is adapted to the maximum relative displacement between the rotating arm 22 and the electric waste removal machine 3. The automatic reel 28 is rotatably mounted on the inner wall of the rotating arm 22, and a coil spring is installed inside the automatic reel 28 to wind up the steel wire rope 25. The coil spring is always in a pre-tensioned state, providing continuous tension to the steel wire rope 25. When the rotating arm 22 unfolds or the electric waste cleaner 3 moves, the wire rope 25 can be released or wound synchronously with the movement of the components to avoid jamming. The fixing block 31 is fixedly installed on the top of the electric waste cleaner 3. When the fixing arm 21 and the electric waste cleaner 3 are in a magnetic connection state, the fixing block 31 is fitted into the bottom of the fixing arm 21. The fitting design of the fixing block 31 enables the fixing arm 21 and the electric waste cleaner 3 to be magnetically connected and prevents the wire rope 25 from shifting or getting tangled during the movement of the equipment, ensuring that the tension acts vertically on the rotating arm 22.

[0038] Please see Figure 1-9The bottom of the fixed arm 21 and the rotating arm 22 are respectively provided with a wire-threading groove 26 for the wire rope 25 to be hidden and installed at the bottom of the fixed arm 21 and the rotating arm 22. The width of the groove 26 matches the diameter of the wire rope 25, and the edge of the groove is rounded to prevent the wire rope 25 from being scratched by sharp edges during winding or unwinding. At the same time, it ensures that the wire rope 25 is hidden inside and does not interfere with the push of the electric waste removal machine 3. Two sets of guide wheels 27 are rotatably installed on the inner wall of the wire-threading groove 26, and are respectively located at the bottom of the fixed arm 21 and the rotating arm 22 and are installed corresponding to the wire rope 25. This is to ensure that the wire rope 25 is wound smoothly. The two sets of guide wheels 27 are arranged along the movement trajectory of the wire rope 25. The rolling friction of the guide wheels 27 replaces the sliding friction, which greatly reduces the movement resistance and further reduces the wear and tear of the wire rope 25.

[0039] Please see Figure 1-9 A right-angle geared motor 17 is installed on one side of the lower end of the support frame 1 to drive the screw 18. The right-angle geared motor 17 can smoothly transmit rotational power to the screw 18, realizing precise forward and reverse rotation of the screw 18, thereby driving the electric waste cleaner 3 to move up and down. A control box 11 is fixedly installed on the other side for powering and controlling the right-angle geared motor 17. The control box 11 has a built-in frequency converter, stroke control module and power supply, etc. The speed of the right-angle geared motor 17 can be adjusted and the upper and lower limit strokes can be preset through buttons. At the same time, the operating status of the right-angle geared motor 17 can be monitored in real time. To ensure safe and controllable operation, a base 12 is fixedly installed at the bottom of the support frame 1, and a handle 15 is fixedly installed in the middle of the support frame 1 for pushing the support frame 1. The handle 15 is wrapped with non-slip rubber material and conforms to ergonomic design, allowing easy pushing of the equipment with one hand. It is suitable for quick switching between different work positions in the workshop. Multiple sets of casters 13 are fixedly installed at the bottom of the base 12 for moving the support frame 1. The casters 13 are equipped with a braking system to keep the equipment stable during operation and prevent displacement. It is suitable for various workshop floors such as cement and epoxy.

[0040] Please see Figure 1-9A rotating shaft 23 is fixedly installed at the end of the rotating arm 22 adjacent to the fixed arm 21 to ensure that the rotating arm 22 opens and closes flexibly without jamming around the end of the fixed arm 21. A gear 231 is fixedly installed at the end of the rotating shaft 23 near the connecting plate 14. The gear 231 and the rotating shaft 23 are fixedly connected by a key to prevent the gear 231 from slipping or shifting during transmission. A rack 141 is fixedly installed on the side of the connecting plate 14 near the rotating arm 22. The rack 141 works in conjunction with the gear 231 to rotate and retract the rotating arm 22 as the fixed arm 21 rises. When the slide bar 19 moves upward, the gear 231 rises synchronously with the fixed arm 21 and meshes with the rack 141. The fixed tooth surface of the rack 141 pushes the gear 231 to rotate, thereby driving the rotating arm 22 to retract towards the support frame 1. When the fixed arm 21 moves downward, the gear 231 descends synchronously with the fixed arm 21 and meshes with the rack 141 in the opposite direction. The gear 231 rotates in the opposite direction to push the rotating arm 22 to unfold outward. The length of the rack 141 is adapted to the travel of the fixed arm 21, ensuring that the rotating arm 22 can be fully unfolded to the working state or fully retracted to the top of the support frame 1.

[0041] Please see Figure 1-9 A connecting block 101 is fixedly connected to the top of the support frame 1, and the top of the connecting block 101 is designed with a slope. The angle of the slope is precisely matched with the bottom contour of the rotating arm 22 in the storage state. At the same time, the surface of the slope is covered with an anti-slip rubber pad to increase the friction coefficient with the rotating arm 22. This is used to support the rotating arm 22 when it is in the storage state. When the rotating arm 22 is fully retracted through the transmission of gear 231 and rack 141, its bottom is tightly fitted with the slope of the connecting block 101. The supporting force of the slope is distributed and transmitted along the force direction of the rotating arm 22, which not only avoids the concentrated force on the gear 231 and rack 141 caused by the rotating arm 22 being suspended, but also prevents the rotating arm 22 from shaking or displacing when the equipment is moved.

[0042] Please see Figure 1-9 A telescopic column 24 is fixedly installed on the top of the pressure block 2, and a spring 241 is fixedly installed inside the telescopic column 24. The spring 241 is initially in a pre-tightened state. The telescopic stroke of the telescopic column 24 is adapted to the elastic deformation range of the spring 241 to ensure that the pressure block 2 can form a stable elastic pressure range after contacting the paper product. When the rotating arm 22 presses down with the fixed arm 21, it generates elastic pressure on the pressure block 2. When the pressure block 2 is attached to the top of the stacked paper product, the fixed arm 21 continues to move down and pushes the telescopic column 24 to compress. The spring 241 deforms synchronously and generates a reverse elastic force. This force is evenly transmitted to the surface of the paper product through the pressure block 2, and always maintains sufficient fixing force to prevent the paper product from shifting.

[0043] The working principle of this application is as follows: the operator pushes the equipment through the handle 15 in the middle of the support frame 1, and the universal wheels 13 at the bottom of the base 12 move flexibly. After the electric waste cleaning machine 3 is aligned with the working position of stacked paper products, the braking system of the universal wheels 13 is locked to ensure that the equipment does not move during operation. In the initial state, the fixed arm 21 is fitted with the slide rod 19 on only one side through the slider 32. The sliders 32 on both sides of the electric waste cleaning machine 3 are fitted with the slide rod 19 and the screw 18 respectively. The fixed arm 21 and the electric waste cleaning machine 3 are magnetically attached through the magnetic block 33 and are in a state of up and down linkage. The rotating arm 22 is turned upward and is in a storage state.

[0044] The right-angle reduction motor 17 is started by the control box 11. The right-angle reduction motor 17 drives the screw 18 to rotate. Because the slider 32 on one side of the electric waste cleaner 3 meshes with the screw 18, the rotational motion of the screw 18 is converted into the vertical downward motion of the electric waste cleaner 3. At the same time, the top of the electric waste cleaner 3 and the bottom of the fixed arm 21 are attracted and fixed by the magnetic block 33, which in turn drives the fixed arm 21 to move down synchronously along the slide 16. As the fixed arm 21 moves down, the gear 231 at the end of the rotating shaft 23 meshes with the rack 141 of the connecting plate 14. The rotation of the gear 231 drives the rotating arm 22 to rotate downward around the end of the fixed arm 21 until the pressure block 2 is directly facing the center area of ​​the stacked paper products.

[0045] During the unfolding of the rotating arm 22, the automatic reel 28 on its inner wall winds up the wire rope 25 by the elastic force of the internal coil spring. The wire rope 25 is laid along the wire groove 26 at the bottom of the fixed arm 21 and the rotating arm 22, and the direction of force is changed by the guide wheel 27 in the wire groove 26 to ensure that the wire rope 25 winds up smoothly without jamming. At this time, the two ends of the wire rope 25 are fixed to the automatic reel 28 and the fixed block 31 at the top of the electric waste cleaning machine 3, respectively, so that the pulling mechanism is always in a pre-tight state.

[0046] After the pressure block 2 contacts the top of the paper product, the fixing arm 21 continues to move down with the electric waste removal machine 3. The telescopic column 24 at the top of the pressure block 2 is compressed, and the internal spring 241 deforms to generate elastic pressure. This pressure is evenly applied to the surface of the paper product through the pressure block 2 to achieve flexible fixation of the stacked paper products. At the same time, the elastic pressure can adapt to the slight tilt or uneven thickness of the stacked paper products and always maintain a stable fixation effect without manual intervention.

[0047] When the elastic pressure of the pressure block 2 reaches its maximum value, the right-angle reduction motor 17 continues to drive the screw 18. At this time, the downward pulling force on the magnetic block 33 of the electric waste cleaner 3 and the fixed arm 21 is greater than the magnetic attraction force, and the magnetic block 33 separates. The fixed arm 21 remains fixed due to the reaction force of the paper product and the guiding constraint of the slide rod 19, maintaining the pressing state of the pressure block 2. Driven by the screw 18, the electric waste cleaner 3 continues to move downward along the slide rod 19 and the screw 18. The toothed chain at its bottom is activated, moving from top to bottom to clean the edge waste of the paper product. During the cleaning process, the coil spring of the automatic roller 28 keeps the wire rope 25 taut. The wire rope 25 generates a continuous pulling force on the rotating arm 22, which indirectly ensures that the pressure of the pressure block 2 on the paper product does not decrease and avoids displacement of the paper product during the waste removal process. The electric waste removal machine 3 moves down along the preset stroke to fully cover the edge material area of ​​the paper product and complete the edge material cleaning. The hidden design of the wire groove 26 avoids the wire rope 25 from interfering with the waste removal action, and the guide wheel 27 reduces the friction between the wire rope 25 and the groove wall to ensure a smooth waste removal process.

[0048] After the electric waste removal machine 3 completes the waste removal stroke, the right-angle reduction motor 17 is reversed by the control box 11. The screw 18 drives the electric waste removal machine 3 to move upward until the magnetic block 33 at the top is aligned with the bottom of the fixed arm 21 again. The magnetic block 33 is attracted again, and the linkage between the two is restored. The electric waste removal machine 3 continues to move upward, driving the fixed arm 21 to move upward synchronously along the slide bar 19. The pressure block 2 is separated from the paper product along with the fixed arm 21. The spring 241 in the telescopic column 24 is reset, and the elastic pressure is lost. At this time, the support frame 1 can be pushed to clean the edge material of other parts of the paper product.

[0049] When the passage space is small, or when the waste removal machine is not needed, the right-angle reduction motor 17 can be turned on to drive the electric waste removal machine 3 to move upward, thereby driving the rotating arm 22 to move upward for storage. During the upward movement of the fixed arm 21, the gear 231 at the end of the rotating shaft 23 meshes with the rack 141 of the connecting plate 14 again. The gear 231 rotates in the opposite direction, driving the rotating arm 22 to rotate upward, causing the rotating arm 22 to turn again. When the rotating arm 22 is fully stored, its bottom is in contact with the inclined surface of the connecting block 101. The connecting block 101 provides support force to prevent the rotating arm 22 from shaking. At this time, the whole equipment is easier to store.
