[0002] Gourd film is a new type of inflatable cushioning filling packaging material, mainly made of polyethylene film (PE) or other polymer materials. After being inflated by an inflation device, it forms a protective material composed of multiple bubbles. These bubbles are shaped like a gourd, hence the name gourd film.

[0003] The working principle of the film blowing machine is to heat and melt the plastic particles, and then blow them into a film through a specific mold and a blowing device. In the existing technology, most film blowing machines are not equipped with components for cooling the film when in use, so that the film cannot be cooled quickly during molding, resulting in adhesion of the film during winding, which in turn affects production efficiency and is not practical enough. Therefore, it is necessary to redesign a gourd film high-efficiency film blowing machine to address the above problems. Utility Model Content

The connecting mechanism includes a connecting plate 7 fixedly installed on the upper end surface of the bottom plate 2. The cold air fan 8 is fixedly mounted on the outer wall of the connecting plate 7.

[0027] A blowing pipe 9 is fixedly installed on the outer wall of the outlet pipe of the air cooler 8, and a blowing opening connected to the interior is provided on the inner wall of the blowing pipe 9. A protective cover 10 is fixedly installed on the outer wall of the inlet pipe of the air cooler 8, and a fixing pin 11 is installed by sliding through the outer wall of the protective cover 10. A socket that cooperates with the fixing pin 11 is provided on the outer wall of the inlet pipe of the air cooler 8, and a shift block 12 is fixedly installed on the outer wall of the fixing pin 11. The bottom wall of the shift block 12 is connected to the outer wall of the protective cover 10. The upper end surface of the bottom plate 2 is rotatably installed with a winding shaft through the first support plate 14, and a winding roller 15 is slidably installed on the outer wall of the winding shaft. The outer wall of the first support plate 14 is fixedly installed with a second motor 17 connected to the winding shaft through a first support mechanism. The first support mechanism includes a second support plate 16 fixedly installed on the outer wall of the first support plate 14.

[0028] The second motor 17 is fixedly mounted on the outer wall of the second support plate 16, and a fixed sleeve 18 is rotatably mounted on the outer wall of the winding shaft by a thread, and an extrusion plate 19 is fixedly mounted on the outer wall of the fixed sleeve 18.

The second supporting mechanism includes a third support plate 20 fixedly mounted on the upper end surface of the base plate 2, and the lower extrusion roller 21 is rotatably mounted on the inner wall of the third support plate 20. The outer wall of the rotating shaft of the lower extrusion roller 21 is connected to the second motor 17 through a transmission mechanism.

[0029] When the utility model is used, the material can be poured into the upper hopper 1 during loading, so that the material is concentrated between the two crushing rollers 3 through the two inclined guide plates 6. Then the first motor 5 can drive the crushing rollers 3 to rotate, and one of the crushing rollers 3 drives the other crushing roller 3 to rotate through the two gears 4 that mesh with each other. At this time, the two crushing rollers 3 rotate in opposite directions to crush the material, thereby preventing larger materials from affecting the film blowing effect. After the film is formed, it can be placed in the middle of the blowing pipe 9. At this time, the cooling air blower 8 The cold air can be blown into the inside of the blowing pipe 9, and then blown out from the inside of the blowing pipe 9 through the two blowing ports, thereby improving the cooling efficiency of the film.

[0030] When the film is to be wound up, the winding roller 15 can be first slidably installed on the outer wall of the winding shaft, and then the fixing sleeve 18 can be rotated and installed on the outer wall of the winding shaft through the cooperation of the thread, so that the fixing sleeve 18 can drive the extrusion plate 19 to squeeze and fix the winding roller 15, and then the film can be passed between the lower extrusion roller 21 and the upper extrusion roller 25 and wound around the outer wall of the winding roller 15. At this time, the second motor 17 can drive the winding shaft to rotate, and the winding shaft drives the winding roller 15 to rotate to wind the film. At the same time, the cylinder 23 can drive the upper extrusion roller 25 to descend through the connecting block 24, so that the upper extrusion roller 25 and the lower extrusion roller 21 are close to each other to clamp the film, and in this process, the second motor 17 can drive the upper extrusion roller 25 to rotate through the two pulleys 22 connected by the belt. In the process of the winding roller 15 winding the film, the film can be rolled by the cooperation of the lower extrusion roller 21 and the upper extrusion roller 25, thereby flattening the wrinkles of the film, thereby improving its flatness during winding.
