DETAILED DESCRIPTION

[0023] To describe the technical content, structural features, achieved purpose and effect of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0024] The terms “left” and “right” in this application refer to the attached Figure 2 Left and right shown.

[0025] An embodiment of the present application provides a waste edge film winding device, which is arranged on a trimming device and is used to wind up the waste edge film cut by the trimming device.

[0026] like Figure 1 As shown, the scrap film winding device 100 includes at least one guide mechanism 10 and at least one winding mechanism 20. One winding mechanism 20 is configured with one guide mechanism 10. In the conveying direction of the scrap film, the guide mechanism 10 is upstream of the corresponding winding mechanism 20, and is used to guide the trimmed product and the cut scrap film. The scrap film is guided to the corresponding winding mechanism 20. The scrap film winding device 100 arranges the guide mechanism 10 and the winding mechanism 20 according to the type of product currently produced. When producing multi-layer products, the scrap film winding device 100 is configured with multiple groups of guide mechanisms 10 and winding mechanisms 20. One group of guide mechanisms 10 and winding mechanisms 20 winds up the scrap film of one layer of product. Because the materials of each layer of some multi-layer products are inconsistent, the scrap film is recovered separately to save classification time, which is conducive to the recycling of the scrap film.

[0027] like Figure 2 , 3As shown, each guide mechanism 10 includes a guide cross brace 1 extending in the left-right direction, a pair of inner guide rings 2 arranged opposite to each other in the left-right direction, a pair of outer guide rings 3 arranged opposite to each other in the left-right direction, and a plurality of guide mounting plates 4. The guide cross brace 1 is detachably mounted on the frame of the trimming device; each inner guide ring 2 and each outer guide ring 3 are respectively provided with a guide mounting plate 4, and can be movably mounted on the guide cross brace 1 in the left-right direction through the corresponding guide mounting plates 4; a pair of inner guide rings 2 are arranged on the inner side of a pair of outer guide rings 3, and the distance between the pair of inner guide rings 2 is adjusted according to the width of the product after trimming, and a pair of outer guide rings 3 guide the cut waste edge film on the outer side of the pair of inner guide rings 2.

[0028] like Figure 4-6 As shown, each winding mechanism 20 includes a transmission shaft 5 extending in the left-right direction, a driving device 6 connected to the transmission shaft 5, a pair of baffles 7 arranged opposite to each other on the left and right sides, and a plurality of baffles 8 parallel to the transmission shaft 5. The transmission shaft 5 is rotatably arranged on a fixed cross brace 9 around its own axis, and the fixed cross brace 9 extends in the left-right direction and is detachably mounted on the frame of the trimming device. The driving device 6 is arranged in the middle of the transmission shaft 5, so as to drive the transmission shaft 5 to rotate around its own axis. A pair of baffles 7 are coaxially sleeved on the transmission shaft 5 and are configured to rotate with the transmission shaft 5. The pair of baffles 7 are arranged on the left and right sides of the driving device 6, respectively. A plurality of baffles 8 are respectively installed on a pair of baffles 7 in two groups, and the baffles 8 of each group are arranged on the outer side of the corresponding baffles 7, that is, the baffles 7 are away from the side of the driving device 6, and the baffles 8 of each group are arranged at equal angles around the circumference of the transmission shaft 5. The beginning of the waste edge film on each side is attached to any baffle 8 on the baffle 7 on the corresponding side. When the driving device 6 drives the transmission shaft 5 to rotate, the baffle 7 drives the baffle 8 of the corresponding group to rotate around the axis of the transmission shaft 5. The waste edge film is wound on multiple baffles 8 in the group. The baffle 7 is used to align the side of the waste edge film rolled up by the baffle 8. In the conveying direction of the waste edge film, the position of each outer guide ring 3 corresponds to the position of the baffle 7 on the corresponding side.

[0029] Each baffle rod 8 is designed to be conical, and the diameter of the baffle rod 8 gradually increases from the outside to the inside. Therefore, a group of baffle rods 8 on each baffle plate 7 forms an annular surface that gradually converges outward in the circumferential direction of the transmission shaft 5. The annular surface helps to unload the rolled waste edge film from the winding mechanism 20, reducing the difficulty of unloading.

[0030] like Figure 5As shown, an adjustment assembly 11 is provided on the outside of each baffle 7 and a fixing ring 12 is provided on the inside. The adjustment assembly 11 and the fixing ring 12 cooperate to adjust the position of the baffle 7 on the transmission shaft 5. The adjustment assembly 11 includes a nut 111 and a spring 112 coaxially sleeved on the transmission shaft 5. The nut 111 is provided at the end of the transmission shaft 5 and is threadedly connected to the transmission shaft 5. The spring 112 abuts between the nut 111 and the baffle 7; the fixing ring 12 is coaxially sleeved on the transmission shaft 5. After determining the position of the baffle 7 after left and right adjustment, the fixing ring 12 is fixed on the inside of the baffle 7 to prevent the baffle 7 from deflecting inward during the winding process.

[0031] like Figure 4 , 6 As shown, the transmission shaft 5 is rotatably connected to the fixed cross brace 9 through a pair of support plates 13 arranged opposite to each other on the left and right sides. The pair of support plates 13 are arranged between the pair of baffles 7 and are located on the left and right sides of the driving device 6. The transmission shaft 5 is also penetrated by a pair of support plates 13. In order to enable the transmission shaft 5 to rotate around its own axis relative to the pair of support plates 13, each support plate 13 is provided with a bearing (not shown in the figure), and the bearings are coaxially sleeved on the transmission shaft 5. A retaining spring is also provided on each support plate 13 to prevent the transmission shaft 5 from axial movement. The driving device 6 is fixed to the fixed cross brace 9 through a fixed plate (not shown in the figure).

[0032] The waste edge film winding device of the present application has a simple structure and is easy to install. It can wind up waste edge films for different products and can wind up different types of waste edge films separately, thus having a wide range of applications.

[0033] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, and the scope of protection required by the present application is defined by the attached claims, description and their equivalents.
