Description

Technical Field

[0001] This utility model relates to the field of membrane waste removal technology, specifically to a membrane waste removal device. Background Technology

[0002] Thin film materials are widely used in packaging, electronic devices, medical products and other fields. In their processing, it is often necessary to precisely adhere the film to the surface of the object (such as mold opening, container edge or electronic component substrate) and remove excess material by cutting, stamping and other methods. In traditional processes, the positioning of the film and the removal of excess material are usually completed manually or by semi-automatic equipment: first, the film is conveyed to the target position by a roller, then the operator manually adjusts the pressing device to press the film to the opening of the object, and finally the excess material is removed by a cutter or cutting mechanism.

[0003] A search revealed a device for removing PVC film from KT board scraps, with authorization announcement number CN214353675U. This utility model effectively solves the problems of not being able to promptly package and collect PVC film scraps and manually removing KT board scraps. The inability to promptly package PVC film scraps reduces the space occupied by waste accumulation, while manual removal of KT board scraps reduces production costs and improves production efficiency.

[0004] However, the existing membrane material residue removal devices mentioned above cannot collect and automatically remove the membrane residue. The residue needs to be removed manually or in a semi-automatic manner, which is not conducive to the efficient application of membrane material. Therefore, we propose a membrane material residue removal device. Utility Model Content

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1, as Figures 1-4As shown, this embodiment proposes a film material excess removal device, including a support frame 1, a winding roller 2 rotatably connected to the outer surface of the support frame 1, several sets of guide rollers 3 rotatably connected to the outer surface of the support frame 1, a material removal structure 4 rotatably connected to the outer surface of the support frame 1, and a collection box 5 provided at the lower end of the material removal structure 4; a base 6 is fixedly connected to the outer surface of the support frame 1, and a pressing cylinder 7 is fixedly connected to the upper end of the base 6 corresponding to the outer surface of the support frame 1; an opening for supporting the film coating material is opened on the outer surface of the base 6; a conveying roller 9 is rotatably connected to the outer surface of the support frame 1 for conveying the film material; a conveying motor 10 for driving the conveying roller 9 to rotate is fixedly connected to the back of the support frame 1; the output end of the pressing cylinder 7 corresponds to the opening on the surface of the base 6; several sets of guide rollers 3 are used to guide the conveying direction of the film material; and the pressing cylinder 7 is used to press down to make the film material adhere to the base 6.

[0027] The material removal structure 4 includes a hollow roller 41 rotatably connected to one side surface of the support frame 1. A protrusion 42 is fixedly connected to the outer surface of the hollow roller 41, and a strip-shaped opening 43 is opened on the outer surface of the hollow roller 41. A material removal motor 44 is fixedly connected to the inner surface of the hollow roller 41. A threaded roller 45 is fixedly connected to the output end of the material removal motor 44. A sliding block 46 is movably sleeved on the outer surface of the threaded roller 45, and a protrusion 47 is fixedly connected to the outer surface of the sliding block 46. A servo motor 8 is fixedly connected to the outer surface of the support frame 1 corresponding to the hollow roller 41. The servo motor 8 is used to drive the hollow roller 41 to rotate. The number of protrusions 42 is several groups and they are distributed in a ring array. The number of strip-shaped openings 43 is equal to the number of protrusions 42, and the strip-shaped openings 43 and protrusions 42 are staggered.

[0028] The feeding motor 44 is fixedly connected to the hollow roller 41 by bolts. The threaded roller 45 is driven by the feeding motor 44 to achieve forward and reverse rotation. The sliding block 46 is threadedly connected to the threaded roller 45. The number of protruding plates 47 is equal to the number of strip-shaped openings 43. The protruding plates 47 extend from the openings of the strip-shaped openings 43 to the outside of the hollow roller 41. The maximum outer diameter formed by the rotation of the protruding plates 47 is greater than the maximum outer diameter formed by the rotation of the protruding strips 42. The forward and reverse rotation of the threaded roller 45 enables the sliding block 46 and the protruding plates 47 to move back and forth along the length of the threaded roller 45.

[0029] In this embodiment, during use, the waste material generated during the use of the film material can be wound and collected, and the remaining part of the film material can be automatically removed from the surface of the hollow roller 41 and the convex strip 42. The whole process does not require manual operation and can realize automated removal.

[0030] Example 2, as Figure 5As shown, based on Embodiment 1, it is proposed that the inner chamber 51 is opened inside the shell of the collection box 5, and the inner chamber 51 is connected to the heating tube 52. The heating tube 52 is used to heat the area inside the collection box 5. The number of heating tubes 52 is several groups and the heating tubes 52 are distributed in an array. The upper opening of the collection box 5 corresponds to the lower part of the hollow roller 41 away from the support frame 1.

[0031] In this embodiment, the discarded membrane material residue can be collected uniformly. After collection, the membrane material residue can be heated to form a shrinkable agglomerate structure, thereby reducing its occupied area and facilitating subsequent recycling of the residue.

[0032] In summary, the working principle of this utility model is as follows:

[0033] During use, the user can let the winding roller 2 pass the head of the wound film material through several sets of guide rollers 3 and conveyor rollers 9, and then wrap the film material around the unloading structure 4. During use, the film material is conveyed by the conveyor roller 9, and the excess film material is removed by the winding of the unloading structure 4. During this process, the robot can place the container to be sealed and covered with film at the opening of the base 6, and then press the film material down by the pressing cylinder 7 to achieve sealing and covering. When sealing and covering, the servo motor 8 and the conveyor motor 10 are paused. They are restarted when the film material is conveyed to the servo motor 8 and the conveyor motor 10.

[0034] During use, the servo motor 8 drives the hollow roller 41 to rotate, and the convex strip 42, together with the hollow roller 41, can wrap the excess material wound on it. After the film material on a set of winding rollers 2 is used up, the excess material wrapped on the convex strip 42 and the hollow roller 41 reaches its maximum. At this time, the unloading motor 44 drives the threaded roller 45 to rotate, so that the threaded roller 45, together with the convex plate 47, moves away from the support frame 1. The convex plate 47 can scrape the excess material from the convex strip 42 and the hollow roller 41 into the opening of the collection box 5, thereby automatically completing the removal. The whole process is automated.

[0035] When the leftover material falls into the opening of the collection box 5, it is heated by the heating tube 52 and the temperature is transferred to the inside of the collection box 5. The leftover material will gradually form small clumps from the larger material volume when heated. At this time, the space occupied by the leftover material will be greatly reduced, and the user only needs to clean it periodically.

[0036] In the diagram, A represents the film material being wound and transported.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
