Description

Technical Field

[0001] The utility model belongs to the technical field of water-filled bag production, and more specifically relates to a waste edge winding device. Background Art

[0002] Water-filled bags are generally made by hot pressing multiple layers of film. The outline of the water-filled bag is pressed out on the film using a hot pressing die, and then the waste edges on both sides of the water-filled bag are removed to obtain the water-filled bag.

[0003] The waste edges are generally collected by a waste edge collector. Patent CN201320220478.6 discloses a waste edge collection device for plastic film, which is a waste edge collection machine, including a main machine, a rope pull rod, a rotating shaft, a worm and a spring. The waste edges of the plastic film pass through the rope loop on the rope pull rod and are wound around the rotating shaft. The rotating shaft rotates to pull the waste edges around the rotating shaft. When the rotating shaft pulls the waste edges, a downward force is generated, causing the rope loop on the rope pull rod to swing downward with the movement of the waste edges, thereby driving the rope pull rod and linkage components such as connecting parts to move, so that the force of the waste edges moving downward can be unloaded by the rope pull rod and other linkage components, and then the linkage components and the rope pull rod are reset by the spring, and the cycle repeats.

[0004] The above-mentioned waste edge collection device uses linkage components to unload force to prevent the waste edge from breaking due to excessive friction between the waste edge and the rope loop; in practice, it is found that due to the small contact area between the waste edge and the rope loop, if the film is thin, concentrated force will still occur, causing the waste edge to break.

[0021] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. 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 understood as limiting the present invention.

[0022] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0023] Reference Figures 1 to 2 As shown, a scrap edge winding device includes a base 1, the base 1 is provided with a winding roller 2, a bracket 3, a first drive module 4 and a second drive module 5. The winding roller 2 rotates under the drive of the first drive module 4, and the bracket 3 moves along the axial direction of the winding roller 2 under the drive of the second drive module 5. A pulley 6 is rotatably provided on the bracket 3, and the axial direction of the pulley 6 is parallel to the axial direction of the winding roller 2.

[0024] The outer diameter of the pulley 6 gradually increases from the middle to both ends along its axial direction. The outer diameter of the pulley 6 is not less than 50 mm, and the outer diameter of the ends of the pulley 6 along its axial direction is not less than 100 mm.

[0025] A pulley 6 is used instead of a rope loop. The waste edge first passes around the pulley 6 and then is wound onto the winding roller 2. The outer diameter of the pulley 6 gradually increases from the middle to both ends along its axial direction, so that the waste edge will be restricted in the middle when moving, and the minimum outer diameter of the pulley 6 is 50 mm. When the waste edge is wrapped around the pulley 6, the contact area with the pulley 6 is large enough, and the waste edge will not break. At the same time, the outer diameter of the end of the pulley 6 can be limited, making the outer diameter of the end of the pulley 6 larger, and the end of the pulley 6 can prevent the waste edge from running out of the pulley 6.

[0026] In this embodiment, the minimum outer diameter of the pulley 6 is 60 mm, and the outer diameter of the end portion of the pulley 6 along the axial direction is 110 mm.

[0027] In this embodiment, a blocking frame 7 is fixed on the bracket 3. The blocking frame 7 includes a U-shaped bottom plate 71 and two side plates 72. The bottom plate 71 is located below the pulley 6, and the pulley 6 is located between the two side plates 72. The bottom plate 71 mainly plays an intercepting role. The bottom plate 71 intercepts below the pulley 6, which can prevent the part of the waste connected to the winding roller 2 from below the pulley 6 from running out of the pulley 6.

[0028] In this embodiment, the winding roller 2 includes a rotating shaft (not shown in the figure) rotatably arranged on the base 1 and a sleeve 21 sleeved on the rotating shaft. The sleeve 21 is used to reel in the waste edge. One end of the rotating shaft is connected to the first driving module 4, and the other end of the rotating shaft is suspended in the air. The sleeve 21 is detachably fixed to the rotating shaft. If the sleeve 21 sleeved on the rotating shaft is full, a new sleeve 21 can be replaced.

[0029] Specifically, the sleeve 21 is fastened to the rotating shaft by bolts, so that the sleeve 21 can rotate along with the rotating shaft.

[0030] In this embodiment, the sleeve 21 includes two discs 211 spaced apart along the axial direction of the rotating shaft and a hollow shaft 212 connecting the two discs 211. The hollow shaft 212 is sleeved on the rotating shaft. The base 1 is provided with a roller 8 for supporting the rotation of the disc 211 near the suspended end of the rotating shaft.

[0031] Since one end of the rotating shaft is suspended, after the sleeve 21 is installed, the suspended end of the rotating shaft is prone to tilt downward due to the offset of the center of gravity, affecting the rotation. Therefore, a roller 8 is provided to support the rotation of the disc body 211, thereby supporting the rotating shaft.

[0032] Moreover, in order not to affect the replacement of the sleeve 21, the position of the roller 8 can be adjusted. A slider 81 is provided on the base 1. The slider 81 can be adjusted in a horizontal direction perpendicular to the axial direction of the rotating shaft. The roller 8 is set on the slider 81.

[0033] When the sleeve 21 needs to be replaced, the slider 81 is moved away from the bottom of the disc 211 so that the sleeve 21 can be pulled out without being blocked by the roller 8; after replacing the sleeve 21, the slider 81 is moved to the bottom of the disc 211 so that the disc 211 contacts the roller 8 so that the roller 8 can support the rotation of the disc 211.

[0034] Specifically, a guide rail is provided on the base 1, and the slider 81 slides with the guide rail. The slider 81 can be self-locking. When the slider 81 moves to a preset position, the slider 81 is locked and fixed on the guide rail.

[0035] In this embodiment, the first drive module 4 includes a first motor and a belt drive assembly, which transmits the connection between the rotating shaft and the first motor; the second drive module 5 includes a second motor and a screw assembly, and the bracket 3 is connected to the screw nut of the screw assembly. The second motor drives the screw to rotate, thereby moving the screw nut, and the screw nut then drives the bracket 3 to move.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
