DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] Referring to Figures 1 to 4 The utility model provides the following technical scheme: An automatic film feeding device suitable for automatic film feeding.

[0023] Specifically, as Figure 1 shown, an automatic film feeding device includes a frame body 1, an air inflation shaft 2, a first clamp roller 3, and a second clamp roller. The air inflation shaft 2 is arranged at the bottom of the frame body 1. The first clamp roller 3 and the second clamp roller are oppositely arranged at the top of the frame body 1. The first clamp roller 3 and the second clamp roller are both sleeved with an anti-skid assembly 4.

[0024] In this embodiment, first, the lifting cylinder 9 is used to compress air to generate sufficient air pressure. Then, the compressed air is transmitted to the air nozzle of the air inflation shaft 2 through the pipeline inside the cylinder. When the compressed air enters the air inflation shaft 2, it will push the piston or air bag inside the shaft to expand. As the expansion proceeds, the surface of the air inflation shaft 2 will gradually lift up and automatically feed the film. Further, after the film material is pushed by the air inflation shaft 2, it further passes between the first clamp roller 3 and the second clamp roller. Since the first clamp roller 3 and the second clamp roller are both provided with the anti-skid assembly 4, they can be suitable for vertical film feeding production, ensuring that the film material can be uniformly and stably automatically fed out.

[0025] In this embodiment, the first clamp roller 3 is driven by a servo motor, and the second clamp roller is driven by a cylinder to approach the first clamp roller 3, thereby clamping the passing film material and further ensuring the stability of the film feeding.

[0026] Specifically, as Figure 3 and Figure 4 shown, the anti-skid assembly 4 includes multiple steel cylinders 41 and multiple anti-skid sleeves 42. The anti-skid sleeves 42 are sleeved on the outside of the steel cylinders 41. The steel cylinders 41 are connected to the outside of the first clamp roller 3 at intervals.

[0027] In this embodiment, the multiple steel cylinders 41 are arranged at intervals on the outside of the first clamp roller 3, so as to further sleeve the multiple anti-skid sleeves 42. Thus, when local wear occurs, only the corresponding steel cylinder 41 needs to be disassembled and replaced, thereby reducing production costs and saving resources. In addition, the second clamp roller has the same structure as the first clamp roller 3.

[0028] In this embodiment, the anti-skid sleeve 42 can be made of polyurethane plastic material, which can increase the friction during film feeding and ensure that the first clamp roller 3 can carry away the film material.

[0029] Specifically, as Figure 3 and Figure 4 shown, the steel cylinder 41 is provided with multiple clamping grooves. The outer sidewall of the first clamp roller 3 is provided with multiple positioning beads 5 embedded in the clamping grooves at intervals.

[0030] In the embodiment, the flexible connection of the steel cylinder 41 and the first clamp roller 3 is realized by positioning the elastic ball 5 in the clamping groove, which is convenient for quick installation and quick disassembly and replacement.

[0031] Specifically, as shown in Figure 1 and Figure 2 The first clamp roller 3 and the inflatable shaft 2 are provided with a film tension assembly 6 and a floating assembly 7. The film tension assembly 6 includes a first roller 61 and a second roller 62, and the first roller 61 and the second roller 62 are arranged between the first clamp roller 3 and the inflatable shaft 2. The floating assembly 7 is arranged between the first roller 61 and the second roller 62. The floating assembly 7 includes a floating rod 71, a pair of sliding seats 72 and a pair of sliding rails 73. The pair of sliding rails 73 are oppositely arranged at the two side ends of the frame body 1, and the sliding rails 73 are vertically arranged between the first roller 61 and the second roller 62. The two ends of the floating rod 71 are connected with the sliding rails 73 through the sliding seats 72. The top end of the sliding rail 73 and the bottom end of the sliding rail 73 are provided with limiting stoppers 8.

[0032] In the embodiment, the film material is S-shaped and crossed and sequentially wound on the inflatable shaft 2, the first roller 61, the floating rod 2 and the second roller 62, and finally stably sent out from between the first clamp roller 3 and the second clamp roller. The film material transmission tension can be further ensured by the first roller 61 and the second roller 62, and the film is further smoothed by the floating rod 71 arranged between the first roller 61 and the second roller 62, so that the film material is in a uniform plane state during the transmission process, and the wrinkling condition is avoided.

[0033] In the embodiment, when the film material is S-shaped and crossed and sequentially wound between the first roller 61, the floating rod 2 and the second roller 62, the floating rod 2 can slide up and down according to the action force of the film material during transmission and its own gravity, so as to smooth the film material.

[0034] The above is only a preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
