Description

Technical Field

[0001] The utility model relates to the technical field of blown film machine equipment, in particular to a plastic production blown film machine. Background Technique

[0002] A blown film machine melts plastic particles and then blows them into films. There are many types of blown film machines, such as PE, POF, and PVC, etc. The films blown out with brand-new particles are new materials, with uniform color, clean, and good stretching of the bags. The blown film machine mainly consists of an extruder, a machine head, a die head, a cooling device, a bubble stabilizer, a chevron plate, a traction roller, a winding device, etc. The blown film machine is mainly used for the production of plastic films. However, when the traditional fully automatic blown film machine for plastic film production conveys the film, the pressing effect on the plastic film is poor, which easily causes the plastic film to shift, and then leads to the plastic film falling off the surface of the driving roller. The user needs to re-fix the plastic film, wasting a lot of time of the user and reducing the work efficiency of the user.

[0003] The application number is CN202020227185.0, which discloses a blown film machine for plastic production, including an extruder, a die head, and a film pressing roller. The film pressing roller is arranged above the die head, and also includes a frame and a feeding mechanism and a winding mechanism located on the frame; the feeding mechanism includes a feeding bin, a motor, and a screw; the feeding bin is arranged above the extruder and is communicated with the extruder; a vibration motor is arranged on the outer wall of the feeding bin; the screw is arranged in the extruder and one end is connected to the output shaft of the motor; the motor is arranged outside the extruder; the winding mechanism includes several guide rollers, several telescopic cylinders, and a winding roller; each telescopic cylinder is connected to the frame through a bracket; the guide rollers are arranged between every two telescopic cylinders; the winding roller is arranged below the winding roller. The plastic film produced by the utility model has good quality, and the plastic film is not easy to slacken during winding.

[0004] The blown film machine for fully automatic plastic film production disclosed in the above document has the following defects: during the use of the blown film machine, the blowing component blows the material outwards, and it is necessary to transmit the film forward through structures such as roller shafts when the film is formed, and corresponding limiting structures need to be set to make the film flat and smooth when it is formed. However, this structure cannot adjust the height of the film pressing roller according to the thickness of the plastic film, which has limitations.

[0005] It can be seen from this that the existing blown film machine does not have the function of adjusting the height of the film pressing roller according to the thickness of the film, and it is necessary to improve the existing deficiencies to provide a function that can adjust the height of the film pressing roller according to the thickness of the film. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a plastic production blown film machine to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the present utility model is achieved through the following technical solutions:

The limiting shaft is positioned by the bearing, so that the limiting shaft cooperates with the roller shaft to limit the upper and lower ends of the film. The film is transmitted forward, and the top two sides of the film are limited and fixed by the two pressing rods. When the film thickness is relatively thin, the two positioning rods on both sides are moved downward, and the positioning rods drive the pressing rods to move downward through the sliding rods to fix the top two sides of the film. The two sides of the film are limited by the two fixing plates. When the width of the film is different, the sliding rod slides out of the positioning rod, and the sliding rod drives the pressing rod to adjust left and right, so that the pressing rod can effectively limit films of different widths. The roller shaft is fixed in the fixing plate by the positioning block for rotation. The fixing plate and the connecting rod are fixedly connected by the connecting piece. The mounting block and the sliding block are installed on the connecting rod, strengthening the connection between the two. The transmission structure is supported perpendicular to the ground by the support rod.

The purpose of such a setting is that during the use of the device, the connection block is provided, and the transmission structure can be driven to tilt by adjusting the turning of the connection block.

[0012] Further, the connecting pieces are respectively installed on the outer walls of the bottoms of the two fixing plates, and four mounting blocks are installed on the side where the two fixing plates are close to each other. The purpose of this setting is that during the use of the device, the fixing plates and the connecting rod are fixedly connected through the connecting pieces.

[0013] Further, sliders are installed at the bottoms of the four mounting blocks, and the sliders are slidably connected to the inner wall of the top of the connecting rod. The purpose of this setting is that during the use of the device, the mounting blocks and the sliders are installed on the connecting rod, strengthening the connection between the two.

[0014] The utility model has the following beneficial effects:

[0015] (1) Through the arrangement of the positioning rods, sliding rods and pressing rods in the utility model, the two sides of the top of the film are limited and fixed by the two pressing rods.

On the outer wall of one side of the top of the two fixing plates 201, a bearing 207 is installed. A limiting shaft 208 is rotatably connected to the inner wall of the bearing 207. The purpose of such a setting is that during the use of the device, the blown film machine 101 blows the material forward to form a film, and the film is conveyed forward and dried by the rotation of the roller shaft 202. When the roller shaft 202 rotates, the limiting shaft 208 on one side is driven to rotate by the film moving together at the bottom. The limiting shaft 208 is positioned by the bearing 207, so that the limiting shaft 208 cooperates with the roller shaft 202 to limit the upper and lower ends of the film. The film is conveyed forward, and the top two sides of the film are limited and fixed by the two pressing rods 206. When the film is relatively thin, the two side positioning rods 204 are moved downward. The positioning rods 204 drive the pressing rods 206 to move downward through the sliding rods 205 to fix the two sides of the top of the film. The two sides of the film are limited by the two fixing plates 201. When the width of the film is different, by sliding the sliding rod 205 out of the positioning rod 204, the sliding rod 205 drives the pressing rod 206 to adjust left and right, so that the pressing rod 206 can effectively limit films of different widths. The roller shaft 202 is installed in the fixing plate 201 and rotates through the positioning block 203. The fixing plate 201 and the connecting rod 104 are fixedly connected through the connecting piece 105. The fixing plate 201 and the slider 107 are installed on the connecting rod 104, strengthening the connection between the two. The transmission structure 2 is supported perpendicular to the ground by the support rod 102. The connecting block 103 is provided, and the transmission structure 2 can be driven to tilt by adjusting the turning of the connecting block 103, improving the flexibility of the device.
