Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machines, in particular to a film blowing machine with a hole punching function. Background Technique

[0002] A film blowing machine melts plastic particles and then blows them into films. There are many types of film blowing machines, such as PE, POF, PVC, etc. The films blown from brand-new particles are new materials, with uniform color, cleanliness, and good stretching properties for the bags. Dry polyethylene particles are added to the feeding hopper and enter the screw by the weight of the particles themselves. When the granular material contacts the helical edge of the thread, the rotating helical edge generates a thrust perpendicular to the helical edge surface on the plastic, pushing the plastic particles forward. During the pushing process, due to the friction between the plastic and the screw, the plastic and the barrel, as well as the collision friction between the particles, and also due to the external heating of the barrel, the plastic gradually melts. The molten plastic passes through the head for impurity filtration and comes out from the die orifice of the die head, is cooled by the air ring, blown and inflated, passes through the chevron plate, the haul-off roll, and the finished film is wound into a roll.

[0003] Currently, when the film blowing machines on the market are in use, especially when producing film packaging materials, a punching mechanism needs to be used later to punch holes in the film packaging materials. In actual use, when the punching mechanism punches holes in the film packaging materials, effects such as exhaust, drainage, and air permeability can be achieved, and it is commonly used for making export bags, garbage bags, etc. Most punching mechanisms use tapered pins arranged on the outer wall of the rotating shaft. When the rotating shaft drives the tapered pins to move, the tapered pins punch holes in the film packaging materials at the top of the rotating shaft. However, in most of these methods, the tapered pins are welded to the outside of the rotating shaft, making it impossible to change the spacing and type of the tapered pins themselves according to production requirements later.

The bottom end of the fixing plate 301 is fixedly connected to the top of the bottom plate 1. An adjusting disc 303 is fixedly connected to the outer wall of the rotating shaft 302. An adjusting plate 304 is provided on one side of the adjusting disc 303. A sliding groove 305 is formed on the outer wall of the adjusting plate 304. A moving block 306 is slidably connected inside the sliding groove 305. A groove 307 is formed inside the moving block 306. An arc-shaped plate 308 is provided inside the groove 307. A positioning rod 309 is fixedly connected to the outer wall of the arc-shaped plate 308. One end of the positioning rod 309 penetrates through the outer wall of the moving block 306 and the positioning rod 309 is slidably connected to the moving block 306.

[0026] In a preferred embodiment, a positioning groove 310 is formed inside the sliding groove 305 and one end of the positioning rod 309 is slidably connected to the positioning groove 310. A rotating rod 311 is provided inside the groove 307. A rotating plate 312 is fixedly connected to the outer wall of the rotating rod 311. A limiting block 313 is fixedly connected to the outer wall of the rotating plate 312. When the rotating rod 311 moves, the rotating rod 311 will drive the rotating plate 312 to move, so that the rotating plate 312 moves inside the groove 307.

[0027] In a preferred embodiment, a limiting groove 314 is formed on the outer wall of the arc-shaped plate 308 and the limiting block 313 is slidably connected to the limiting groove 314. A spring 315 is provided between the outer wall of the rotating plate 312 and the groove 307. Both ends of the spring 315 are fixedly connected to the inside of the groove 307 and the outer wall of the rotating plate 312 respectively. When the limiting block 313 moves, the limiting block 313 will move inside the groove 307, and at the same time, the limiting block 313 can move inside the limiting groove 314.

[0028] In a preferred embodiment, an adjusting groove 4 is formed on the outer wall of the adjusting disc 303. An adjusting rod 5 is slidably connected inside the adjusting groove 4.

When the adjusting rod 5 moves, the adjusting rod 5 will move inside the adjusting groove 4, and at the same time, the adjusting rod 5 can drive the moving plate to move.

[0029] Working principle of the utility model: When it is necessary to adjust the left - right spacing and quantity of the taper pins 8, at this time, rotate the rotating rod 311. The rotating rod 311 rotates inside the groove 307. The rotating rod 311 drives the rotating plate 312 to make a small - amplitude circular motion inside the groove 307. The rotating plate 312 drives the spring 315 to move at the same time, so that the spring 315 can be twisted. At the same time, the rotating plate 312 drives the limiting block 313 to move, so that the limiting block 313 moves inside the groove 307. At the same time, the limiting block 313 slides inside the limiting groove 314. Because the cross - sectional shape of the limiting groove 314 is arc - shaped, the rotating plate 312 can drive the arc - shaped plate 308 to move through the limiting block 313 and the limiting groove 314, so that the arc - shaped plate 308 slides inside the groove 307. The arc - shaped plate 308 drives the positioning rod 309 to move, so that the positioning rod 309 moves towards the direction of the rotating rod 311. One end of the positioning rod 309 is separated from the positioning groove 310 at the same time. When one end of the positioning rod 309 is completely separated from the positioning groove 310, at this time, pull the moving block 306, so that the taper pin 8 can be easily disassembled from the rotating shaft 302, or pull the moving block 306, so that the moving block 306 slides inside the sliding groove 305, resulting in the left - right adjustment between the taper pins 8 on the top of the subsequent moving block 306 being convenient. At the same time, the moving block 306 can be disassembled and new moving blocks 306 can be added according to the usage needs, so that the quantity of the taper pins 8 in each row can be adjusted adaptively according to the requirements. When the quantity and left - right spacing of the taper pins 8 are adjusted, the film blowing machine body 2 blows the film, so that the film body is stretched through the top of the rotating shaft 302 after passing through multiple rollers. At this time, start the motor on one side of the rotating shaft 302, so that the motor output shaft drives the taper pins 8 through the rotating shaft 302, and the taper pins 8 perforate the film body on the top.

[0030] Please refer to Figure 1 and Figure 2 As shown in, the technical solution provided by the utility model is: A clamping groove 6 is opened on the outer wall of the adjusting disc 303. A stabilizing plate 9 is fixedly connected to the outer wall of the adjusting rod 5. A threaded rod 7 penetrates through the stabilizing plate 9 and the threaded rod 7 is thread - connected to the stabilizing plate 9. When the rotating rod 311 moves, the rotating rod 311 drives the rotating plate 312 to move, so that the rotating plate 312 can drive the spring 315 to be twisted subsequently.

[0031] In a preferred embodiment, one end of the threaded rod 7 is thread - connected to the inside of the clamping groove 6. The outer wall of the moving block 306 is fixedly connected with a taper pin 8. When the threaded rod 7 moves, the threaded rod 7 moves with the stabilizing plate 9 through the thread, and at the same time, one end of the threaded rod 7 moves with the clamping groove 6 through the thread.

[0032] Working principle of the utility model: When it is necessary to adaptively adjust the distance between the upper and lower tapered holes of the membrane body, at this time, rotate the threaded rods 7 on both sides of the adjusting plate 304, so that the threaded rods 7 move through the threads with the stabilizing plate 9. At the same time, one end of the threaded rod 7 moves through the threads with the engaging groove 6, causing one end of the threaded rod 7 to be separated from the engaging groove 6. At this time, the adjusting plate 304 can be pulled, so that the adjusting plate 304 drives the adjusting rod 5 to move. The adjusting rod 5 makes an arc-shaped movement inside the adjusting groove 4. When the adjusting plate 304 reaches the appropriate position, at this time, reverse the threaded rod 7, so that one end of the threaded rod 7 enters the inside of the engaging groove 6, thereby facilitating the adaptive adjustment of the distance between the upper and lower tapered holes of the subsequent membrane body.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
