Description

Technical Field

[0001] This utility model relates to the field of plastic film preparation technology, specifically to a cooling mechanism for a blown film machine used in plastic film preparation. Background Technology

[0002] Plastic film refers to plastic products made primarily from polymer synthetic materials, mixed with other auxiliary materials in a certain proportion, and then formed on plastic molding machinery. These films have a certain thickness, width, and unlimited length, with a smooth, soft surface. Plastic film is widely used in the packaging industry, serving as both packaging material and a laminating layer. The market share of plastic packaging and plastic packaging products is increasing, especially composite plastic flexible packaging, which is widely used in the food, pharmaceutical, and chemical industries. Food packaging accounts for the largest proportion, including beverage packaging, frozen food packaging, retortable food packaging, and fast food packaging. These products have brought great convenience to people's lives. To improve the efficiency of plastic film production, a cooling mechanism is needed; however, existing cooling mechanisms still have the following shortcomings:

[0003] For example, the utility model with publication number CN217597802U discloses a cooling mechanism for a blown film machine used in the preparation of plastic film. This utility model solves the problems of poor cooling effect and inconvenience in cleaning dust from the surface of the cooled plastic film due to the single cooling method in the prior art. However, similar to the prior art of the above application, when the existing cooling mechanism is used, since most cooling mechanisms do not have a structure for limiting and conveying plastic film, the plastic film is prone to positional displacement during cooling processes such as air cooling, which affects the subsequent winding of the plastic film, resulting in a decrease in the practicality and efficiency of the cooling mechanism.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a cooling mechanism for blown film preparation of plastic film. Utility Model Content

[0005] The purpose of this invention is to provide a cooling mechanism for a blown film extrusion machine used in plastic film preparation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling mechanism for a blown film extrusion machine for plastic film preparation, comprising a receiving base and a feeding assembly. The receiving base has supporting columns installed at its bottom, and a take-up roller is provided on the upper right side of the receiving base. Feeding assemblies are provided on both sides of the upper end of the receiving base, and each feeding assembly includes a mounting plate, a pneumatic rod, a mounting frame, a spring damping rod, a receiving frame, a feeding roller, a limiting slider, a limiting through hole, and a limiting crossbar. A pneumatic rod is installed on the upper inner side of the mounting plate, and a mounting frame is installed at the front end of the pneumatic rod. A spring damping rod is provided at the upper inner end of the mounting frame, and a receiving frame is installed at the front end of the spring damping rod. A feeding roller is connected inside the receiving frame. A limiting slider is installed in the middle of the lower end of the mounting frame, and a limiting through hole is opened in the middle of the limiting slider. A limiting crossbar is connected inside the limiting through hole. A cooling assembly is provided in the middle of the upper end of the receiving base.

[0007] Furthermore, the pneumatic rod is perpendicular to the mounting frame, and the pneumatic rod is fixedly connected to the mounting frame by bolts.

[0008] Furthermore, the spring damping rods are distributed perpendicularly to the support frame, and the support frame is elastically connected to the mounting frame through the spring damping rods.

[0009] Furthermore, the internal dimensions of the limiting through hole are adapted to the external dimensions of the limiting crossbar, and the limiting crossbar is embeddedly connected to the limiting slider through the limiting through hole.

[0010] Furthermore, the cooling assembly includes a mounting bracket, a receiving frame, a filter box, and a fan. The receiving frame is mounted on the upper end of the mounting bracket, and a filter box is provided on the upper right side of the receiving frame, with a fan connected to the left side of the filter box.

[0011] Furthermore, the cooling assembly also includes an air supply pipe, an air collection chamber, and an air outlet. The air supply pipe is connected to the left side of the fan, the front end of the air supply pipe is connected to the air collection chamber, and an air outlet is provided outside the air collection chamber.

[0012] Furthermore, there are two air collection chambers, and the two air collection chambers are symmetrically arranged on both sides of the receiving frame with respect to the side center axis of the receiving frame.

[0013] Furthermore, the air outlets are equidistantly distributed outside the air collection chamber, and the air outlets are fixedly connected to the air collection chamber by bolts.

[0014] This utility model provides a cooling mechanism for a blown film extrusion machine for plastic film preparation, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of the material conveying component, enables the installation frame to be adjusted in use by the pneumatic rod when the cooling mechanism of the blown film machine for plastic film preparation is used. The spring damping rod makes the material conveying roller elastically connected to the installation frame, so that the material conveying roller can limit the conveying of plastic films of different thicknesses. The limiting slider is fixedly installed in the middle of the lower end of the installation frame. The limiting through hole and the limiting crossbar increase the stability of the limiting slider during the movement of the limiting slider, thereby avoiding the position deviation of the installation frame during the movement, improving the stability of the cooling mechanism in conveying plastic film, and improving the overall winding effect of plastic film.

[0016] 2. By setting up a cooling component, this utility model enables the cooling mechanism of a blown film machine for plastic film preparation to draw air into the air supply pipe through the operation of the fan on the left side of the filter box. At the same time, the air is filtered by the filter box and then transported to the air collection chamber through the air supply pipe. The air entering the air collection chamber is then evenly delivered out through the air outlet, thereby uniformly cooling the plastic film and improving the overall practicality and efficiency of the cooling mechanism.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 2As shown, a cooling mechanism for a blown film extrusion machine for plastic film preparation includes a receiving base 1 and a feeding assembly 4. The receiving base 1 has a support column 2 mounted on its bottom, and a take-up roller 3 is located on the upper right side of the receiving base 1. The feeding assembly 4 is located on both sides of the upper end of the receiving base 1. The feeding assembly 4 includes a mounting vertical plate 401, a pneumatic rod 402, a mounting frame 403, a spring damping rod 404, a receiving frame 405, a feeding roller 406, a limiting slider 407, a limiting through hole 408, and a limiting crossbar 409. The pneumatic rod 402 is mounted on the upper inner side of the mounting vertical plate 401, and the mounting frame 403 is mounted on the front end of the pneumatic rod 402. The upper inner side of the mounting frame 403... A spring damping rod 404 is provided, and a receiving frame 405 is installed at the front end of the spring damping rod 404. A conveying roller 406 is connected inside the receiving frame 405. A limit slider 407 is installed at the middle of the lower end of the mounting frame 403, and a limit through hole 408 is opened in the middle of the limit slider 407. A limit crossbar 409 is connected inside the limit through hole 408. The pneumatic rod 402 is perpendicular to the mounting frame 403 and is fixedly connected to the mounting frame 403 by bolts. The spring damping rod 404 is perpendicular to the receiving frame 405, and the receiving frame 405 is elastically connected to the mounting frame 403 through the spring damping rod 404. The limit through hole... The internal dimensions of 408 are compatible with the external dimensions of the limiting crossbar 409, and the limiting crossbar 409 is embeddedly connected to the limiting slider 407 through the limiting through hole 408. The mounting vertical plate 401 is fixedly installed on both sides of the upper end of the receiving base 1 by fastening bolts, and the pneumatic rod 402 is fixedly installed on the upper inner side of the mounting vertical plate 401 with the fastening bolts. The pneumatic rod 402 drives the mounting frame 403 to adjust its position. The spring damping rod 404 is fixedly installed on the upper inner side of the mounting frame 403. The spring damping rod 404 makes the receiving frame 405 elastically connected to the mounting frame 403. At the same time, the conveying roller 406 is installed inside the receiving frame 405. The spring damping rod 404 enables the feeding roller 406 to be elastically connected to the mounting frame 403, thereby allowing the feeding roller 406 to perform limited feeding of plastic films of different thicknesses. The limiting slider 407 is fixedly installed in the middle of the lower end of the mounting frame 403. The internal dimensions of the limiting through hole 408 inside the limiting slider 407 are adapted to the external dimensions of the limiting crossbar 409. Thus, the limiting through hole 408, in conjunction with the limiting crossbar 409, increases the stability of the limiting slider 407 during movement, thereby preventing the mounting frame 403 from shifting position during movement, improving the stability of the cooling mechanism in feeding the plastic film, and enhancing the overall winding effect of the plastic film.

[0023] like Figure 1 and Figure 3As shown, a cooling assembly 5 is provided at the upper center of the base 1. The cooling assembly 5 includes a mounting bracket 501, a receiving frame 502, a filter box 503, and a fan 504. The receiving frame 502 is mounted on the upper end of the mounting bracket 501, and the filter box 503 is provided on the upper right side of the receiving frame 502. The fan 504 is connected to the left side of the filter box 503. The cooling assembly 5 also includes an air supply pipe 505, an air collecting chamber 506, and an air outlet 507. The air supply pipe 505 is connected to the left side of the fan 504, and the front end of the air supply pipe 505 is connected to the air collecting chamber 506. An air outlet 507 is provided on the outside of the air collecting chamber 506. There are two air collecting chambers 506, and the two air collecting chambers 506 are symmetrically arranged on both sides of the receiving frame 502 about the side center axis of the receiving frame 502. The air outlet 507... The air outlets 507 are evenly distributed outside the air collection chamber 506, and are fixedly connected to the air collection chamber 506 by bolts.

The filter box 503 is fixedly installed on the upper right side of the receiving frame 502. The fan 504 on the left side of the filter box 503 operates to draw air into the air supply pipe 505. At the same time, the filter box 503 filters the air and delivers it to the air collection chamber 506 through the air supply pipe 505. The air entering the air collection chamber 506 is evenly delivered out through the air outlets 507, thereby uniformly cooling the plastic film and improving the overall practicality and efficiency of the cooling mechanism.

[0024] In summary, the cooling mechanism of this blown film extrusion machine for plastic film preparation, during use, firstly enhances the stability of the equipment through the support columns 2 installed at the bottom of the base 1, then uses the winding roller 3 installed on the upper right side of the base 1 to wind up the plastic film. The pneumatic rod 402 drives the mounting frame 403 to adjust its position. A spring damping rod 404 is fixedly installed inside the upper part of the mounting frame 403, allowing the feed roller 406 to elastically connect with the mounting frame 403. This enables the feed roller 406 to perform limited conveying of plastic films of different thicknesses. The limiting slider 407 is fixedly installed on the mounting frame. At the lower center of the mounting frame 403, a limiting through hole 408, in conjunction with a limiting crossbar 409, increases the stability of the limiting slider 407 during movement, thereby preventing positional deviation of the mounting frame 403 during movement. Then, the fan 504 on the left side of the filter box 503 draws air into the air supply pipe 505, where the filter box 503 filters the air. The air is then delivered to the air collection chamber 506 via the air supply pipe 505, and the air entering the air collection chamber 506 is evenly delivered through the air outlet 507, thereby uniformly cooling the plastic film and improving the overall practicality and efficiency of the cooling mechanism.
