[0002] Film crushing refers to the process of breaking film materials (such as plastic films, metal films, etc.) into small particles or powders through mechanical, chemical or other processing methods. The purpose of film crushing is usually to recycle waste film materials, treat waste, process materials or increase surface area. In this process, the film can be more easily handled, transported, stored or processed into other forms of products after being crushed.

[0003] A Chinese utility model patent with publication number CN219667160U discloses a film crushing device, in which a crushing rod and a crushing knife arranged in a first crushing barrel crush the film in the first crushing barrel. After being crushed to a certain extent, the crushed film falls into the second crushing barrel through the connecting pipe and the mesh holes on the first filter net, forming a secondary crushing effect on the film, thereby realizing effective crushing processing of the film.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] See also Figure 1-4 The utility model provides a film crushing device, including a mounting frame 1, a top side of the mounting frame 1 is rotatably connected with a mounting shaft 2 in a left-right axial direction through a bearing, and a columnar shell 3 is fixedly connected to the side of the mounting shaft 2 away from the mounting frame 1, and a feed port and a discharge port are respectively provided on the upper and lower sides of the shell 3, and are closed by a cover plate, and a rotatable blade 4 for cutting and crushing the film is provided in the shell 3, and a rotating mechanism for rotating the mounting shaft 2 is provided on the mounting frame 1. Through such a design, the cover plate of the top discharge port can be opened to pour the film to be crushed into the shell 3, and the film in the shell 3 can be shredded by the rotating blade 4, and at the same time, the mounting shaft 2 can be rotated under the action of the rotating mechanism, so that the shell 3 can rotate synchronously with the mounting shaft 2, so that the film in the shell 3 can be continuously flipped and rolled so that it can contact with the rotating blade 4 more evenly, so as to be continuously cut into pieces, so that the film can be efficiently shredded to form qualified particles.

[0023] In order to enable the mounting shaft 2 to rotate, the rotating mechanism includes a synchronous wheel 5 rotatably arranged on one side of the mounting frame 1 and located directly below the mounting shaft 2, a synchronous wheel 2 6 is fixedly sleeved on the mounting shaft 2, a synchronous belt 7 is wound between the synchronous wheel 5 and the synchronous wheel 2 6 through the tooth grooves, and a driving mechanism for driving the synchronous wheel 5 to rotate is arranged on the mounting frame 1. When the synchronous wheel 5 rotates, it can drive the synchronous wheel 2 6 to rotate synchronously through the synchronous belt 7, thereby driving the mounting shaft 2 to rotate, allowing the shell 3 to start rotating and flipping the film inside it.

[0024] Specifically, the driving mechanism includes a mounting shaft 28 and a servo motor 19. The mounting shaft 28 is rotatably plugged into the mounting frame 1 through a bearing, and the synchronous wheel 15 is fixedly sleeved on one side of the mounting shaft 28. The servo motor 19 is fixedly mounted on one side of the mounting frame 1, and the output shaft end of the servo motor 19 is fixed to one end of the mounting shaft 28. When the output shaft of the servo motor 19 rotates, it can drive the mounting shaft 28 to rotate synchronously, and achieve the purpose of driving the synchronous wheel 15 to rotate.

[0025] See also Figure 3 Two vertically symmetrical mounting rods 10 are fixedly connected in the shell 3, and a rotating rod 11 is rotatably inserted between the two mounting rods 10 through a bearing. The number of blades 4 is multiple groups, and each group of blades 4 is fixedly installed on the rotating rod 11 with linear and equal spacing, so that multiple groups of blades 4 can be installed in the shell 3, which is more reasonable.

[0026] In order to enable multiple sets of blades 4 to rotate to shred the film, it is proposed that a rotating shaft 12 axially perpendicular to the rotating rod 11 is rotatably connected to one side of the shell 3 through a bearing, one end of the rotating shaft 12 is fixedly connected to a bevel gear 13, an annular plate 14 is fixedly sleeved on the rotating rod 11, and the top of the annular plate 14 is fixedly connected to an end face gear 15 meshing with the bevel gear 13, and a driving member for driving the rotating shaft 12 to rotate is provided on the shell 3. When the rotating shaft 12 rotates, the bevel gear 13 can drive the end face gear 15 to rotate through tooth matching. At this time, the annular plate 14 can drive the rotating rod 11 to rotate, so that the multiple sets of blades 4 on the rotating rod 11 can rotate at high speed in the shell 3 and achieve the effect of shredding the film.

[0027] Furthermore, the driving member includes a servo motor 16 fixedly mounted on the surface of the shell 3, one end of the rotating shaft 12 passes through the shell 3 and is fixedly connected to the end of the output shaft of the servo motor 16, so that when the output shaft of the servo motor 16 rotates, the purpose of driving the rotating shaft 12 to rotate can be achieved.

[0028] It should be noted that a fixing rod 18 is fixedly connected to one side of the inner wall of the shell 3, and a protective cover 17 is fixedly connected to the fixing rod 18. The rotating rod 11 and the rotating shaft 12 are both passed through the protective cover 17 through bearings, and the bevel gear 13 and the end face gear 15 are both located inside the protective cover 17, so that the protective cover 17 wraps and covers the bevel gear 13 and the end face gear 15 to prevent the shredded film powder in the shell 3 from falling into the teeth of the bevel gear 13 / end face gear 15, causing the bevel gear 13 / end face gear 15 to be unable to engage and rotate normally.

[0029] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
