Description

Technical Field

[0001] This utility model relates to the field of edge material recycling technology, specifically to an edge material recycling device for packaging and printing production. Background Technology

[0002] Packaging printing is printing on various packaging bag materials. Currently, during the trimming process of packaging bag printing production, a large amount of scrap material is generated. This scrap material is usually piled up directly next to the equipment, causing inconvenience to production and processing, and also affecting the workshop environment.

[0003] Patent document CN222647283U discloses a device for recycling edge materials in packaging printing production. This device, through the coordinated arrangement of a drive motor, transmission rod, sleeve, take-up roller, movable frame, threaded hole, fastening bolt, movable plate, spring, limit switch, alarm, electric push rod, connecting plate, and cutter, works by passing the edge material through the guide wheel and cutter and wrapping it around the take-up roller. The drive motor then rotates the transmission rod, simultaneously winding the take-up roller. When the edge material on the take-up roller reaches a certain thickness, the movable plate moves downwards due to the thickness, triggering the limit switch. This transmits information to the control panel, which then stops the drive motor and activates the electric push rod to cut the edge material, facilitating recycling. However, in this solution, replacing the take-up roller is cumbersome, requiring the removal of the existing roller and installation of a new one, and it cannot quickly rewind subsequent edge material.

[0004] Patent document CN216940991U discloses an edge material recycling device for packaging and printing production. A motor output drives a circular shaft on a material take-up drum to rotate inside a bearing. During this process, the rotation of the circular shaft on the edge material take-up drum within the bearing is achieved through the cooperation of two pulleys and a transmission belt, thus simultaneously recycling and processing both finished products and edge materials. However, this technical solution also suffers from the aforementioned problems: replacing the take-up roller is cumbersome, requiring the removal of the take-up roller wrapped with edge material and the installation of a new one, and it cannot achieve rapid winding of subsequent edge materials. Utility Model Content

[0005] The main purpose of this invention is to provide an edge material recycling device that allows for easy replacement of the take-up roller and rapid collection of subsequent edge materials.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A scrap recycling device for packaging printing production includes a support frame, a rotating shaft rotatably connected to the support frame, a motor fixed on the support frame, the output shaft of the motor being concentrically fixed to the rotating shaft, a flat key fixed to the outside of the rotating shaft, multiple take-up rollers sleeved on the rotating shaft, keyways that mate with the flat key being opened on the inner wall of the take-up rollers, the flat key being located in the keyways, and a sliding groove being opened on the outer edge of the rotating shaft, the length direction of the sliding groove being parallel to the axial direction of the rotating shaft, and blocking members being slidably engaged in the sliding grooves on both sides of the multiple take-up rollers, with locking handles threadedly connected to the blocking members, the locking handles being tightly pressed against the bottom of the sliding groove.

[0007] Specifically, the bracket includes a vertical part and a horizontal part, a rotating shaft is rotatably connected to the vertical part, a motor is fixed to the vertical part, and multiple mounting holes are provided on the horizontal part.

[0008] Specifically, the vertical and horizontal parts of the bracket are fixedly connected by inclined struts.

[0009] Specifically, the slide is a dovetail groove, and there are two slides, which are symmetrically arranged according to the axis of rotation.

[0010] Specifically, the blocking component includes a slide rod with a dovetail-shaped cross-section. A locking handle is threaded onto the slide rod. A stop bar is fixed to the side of the slide rod away from the bottom of the chute. The stop bar is perpendicular to the slide rod, and the end of the stop bar away from the slide rod is located outside the chute. The stop bar abuts against the side of the take-up roller on one side.

[0011] Specifically, there are two flat keys, which are symmetrically arranged according to the axis of the rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the cooperative design of the chute and the blocking component, the axial position adjustment, clamping and disassembly process of the winding roller is simple and quick, which greatly reduces the time of manual intervention, supports continuous operation of edge material winding, and effectively improves production efficiency.

[0013] 2. The fit between the flat key and the keyway ensures that the rotating shaft and the take-up roller rotate synchronously, avoiding slippage; the symmetrical distribution of the slide and the flat key optimizes the mechanical balance, significantly suppresses vibration and eccentricity during rotation, and enhances the stability and reliability of the equipment operation.

[0014] 3. The dovetail groove and locking handle mechanism provide reliable clamping and fixing, preventing loosening during the winding process; at the same time, the detachable design of the blocking parts facilitates quick replacement and maintenance of the winding roller. The winding roller station can be switched by adjusting the position of the blocking parts, realizing continuous recycling of edge material, improving production efficiency, reducing downtime frequency, and extending equipment service life.

[0015] 4. The modular layout of the take-up rollers allows for flexible adjustment of their position to accommodate different edge material specifications; the design of the vertical, horizontal and mounting hole sections of the bracket takes into account both space optimization and external component expansion, improving the versatility and compatibility of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figures 1-4 As shown, a scrap recycling device for packaging printing production includes a support 1, a rotating shaft 4 rotatably connected to the support 1, a motor 10 fixed on the support 1, and the output shaft of the motor 10 being concentrically fixedly connected to the rotating shaft 4.

[0023] The bracket 1 includes a vertical part and a horizontal part, which are fixedly connected by an inclined support rod 2. A rotating shaft 4 is rotatably connected to the vertical part, and a motor 10 is fixed to the vertical part. Multiple mounting holes 3 are provided on the horizontal part.

[0024] A flat key 5 is fixed on the outside of the rotating shaft 4. Multiple take-up rollers 11 are sleeved on the rotating shaft 4. A keyway that mates with the flat key 5 is opened on the inner wall of the take-up roller 11. The flat key 5 is located in the keyway.

[0025] The outer edge of the rotating shaft 4 is provided with a slide groove 6, which is a dovetail groove. The length direction of the slide groove 6 is parallel to the axial direction of the rotating shaft 4. Multiple take-up rollers 11 are slidably engaged with blocking parts in the slide groove 6 on both sides. The blocking parts are threaded with locking handles 9, which are pressed against the bottom of the slide groove 6.

[0026] The blocking component includes a slide rod 7, which has a dovetail-shaped cross-section. A locking handle 9 is threaded onto the slide rod 7. A stop bar 8 is fixed on the side of the slide rod 7 away from the bottom of the groove 6. The stop bar 8 is perpendicular to the slide rod 7. The end of the stop bar 8 away from the slide rod 7 is located outside the groove 6. The stop bar 8 is pressed against the side of the take-up roller 11 on one side.

[0027] Before winding up the edge material, multiple winding rollers 11 are pre-mounted on the rotating shaft 4, with the flat key 5 positioned within the keyway of the winding roller 11. Rotation of the rotating shaft 4 drives the multiple winding rollers 11 to rotate. Then, the axial position of the multiple winding rollers 11 on the rotating shaft 4 is adjusted so that the blocking elements on both sides of the multiple winding rollers 11 move closer together, clamping the multiple winding rollers 11. In specific operation, the locking handle 9 is loosened, causing the stop rod 8 and slide rod 7 to move towards the winding rollers 11. The stop rods 8 on both sides of the slide rod 7 within the slide groove 6 clamp the multiple winding rollers 11. Then, the locking handle 9 is rotated, pressing it firmly against the bottom of the slide groove 6. At this point, the slide rod 7 and stop rod 8 are positioned, and the stop rods 8 on both sides clamp the multiple winding rollers 11.

[0028] When positioning multiple take-up rollers 11, the take-up roller 11 that is furthest from the support 1 is aligned with the edge material, so that the take-up roller 11 that is furthest from the support 1 can continuously take up the edge material when rotating with the shaft 4.

[0029] When winding the edge material, one end of the edge material is fixed on a winding roller 11 that is far away from the support 1. During the winding process of the packaging bag, the motor 10 is started to wind the edge material at the same time.

[0030] After the edge material is wound up, loosen the locking handle 9 on the blocking member away from the support 1 and remove the blocking member away from the support 1. Then the winding roller 11 wrapped with edge material can be removed from the rotating shaft 4.

[0031] Loosen the locking handle 9 on the blocking member near the support 1, and use the blocking member on the right to push the multiple take-up rollers 11 on the rotating shaft 4 away from the support 1 until the take-up roller 11 farthest from the support 1 corresponds to the cut edge material.

[0032] Reinstall the removed blocking parts onto the rotating shaft 4, and use the blocking parts on both sides to clamp the multiple winding rollers 11 on the rotating shaft 4. Locking the locking handles 9 on the blocking parts will allow the subsequent edge material to be wound up.

[0033] Example 2: Based on Example 1, there are two slide grooves 6, which are symmetrically arranged with respect to the axis of the rotating shaft 4. There are also two flat keys 5, which are symmetrically arranged with respect to the axis of the rotating shaft 4.

[0034] To improve the stability of the rotating shaft 4 and multiple take-up rollers 11 during rotation, two slide grooves 6 and two flat keys 5 are set and symmetrically arranged according to the axis of the rotating shaft 4. The two slide grooves 6 and two flat keys 5 achieve mechanical balance through geometric symmetry, optimize load distribution and stress diffusion, and thus significantly suppress vibration and eccentricity during the rotation of the rotating shaft 4 and the take-up rollers 11.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
