Description

Technical Field

[0001] The present application relates to the technical field of feeding of plastic film blowing machines, and in particular to a plastic film blowing machine. Background Art

[0002] Film blowing is a plastic processing method, which refers to the molten material plasticized by the extruder barrel, extruded through a forming mold into a cylindrical film blank, and then blowing air with a certain pressure into the barrel to inflate the cylindrical film blank plastic to achieve the film barrel diameter and thickness required by production, and then cooled and shaped into a film product. This kind of blown film is generally produced with polyethylene, polypropylene and polyvinyl chloride resins. The film formed by film blowing has uniform color, is clean, and has good stretchability. The film blowing machine is the equipment for implementing film blowing.

[0003] Generally, the raw material of film blowing is plastic particles, which are generally manually lifted and poured into a storage barrel by lifting a packaging bag. However, since the packaging bag filled with plastic particles is a flexible structure, during the process of feeding the plastic particles, the staff needs to hold the packaging bag all the time and continuously pull the packaging bag upward to make the opening of the packaging bag face downward, so that the plastic particles in the packaging bag can flow smoothly into the feed hopper through gravity. However, the packaging bag filled with rapeseed is relatively large in size and weight, so the staff will cause physical fatigue if they hold and continuously pull the packaging bag for a long time, which will consume a lot of manpower, thus affecting the staff's work efficiency and being very inconvenient. Therefore, those skilled in the art provide a plastic film blowing machine to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-5 This application is described in further detail.

[0025] The present application embodiment discloses a plastic film blowing machine. Figure 1-5 A plastic film blowing machine comprises a film blowing machine body 1, a support plate 4, a baffle plate 42 and a support assembly 6. A feed pipe 2 is arranged above the film blowing machine body 1, a material storage channel 3 is arranged above the feed pipe 2, a notch 31 is opened on one side of the material storage channel 3, a support plate 4 is rotatably arranged on one side of the outer wall of the material storage channel 3, one end of the support plate 4 extends to the inside of the notch 31, and a handrail 5 is fixedly connected to the other side of the support plate 4. Two groups of baffle plates 42 are arranged, and the two groups of baffle plates 42 are located on both sides of the support plate 4. The support assembly 6 is arranged on the material storage channel 3 and is located below the support plate 4;

[0026] In this way, during the implementation process, when it is necessary to feed the film blowing machine body 1, the staff can rotate the support assembly 6, and support the support plate 4 through the support assembly 6 to keep the support plate 4 horizontal. Then the staff will place the packaging bag filled with plastic particles on the top of the support plate 4, and point the opening of the packaging bag toward the storage channel 3, so that the plastic particles flow into the inside through the notch 31 of the storage channel 3. The plastic particles inside the storage channel 3 will flow into the inside of the film blowing machine body 1 through the feeding pipe 2, so that the film blowing machine body 1 blows the plastic film.

[0027] When a part of the plastic inside the packaging bag can flow out, the staff grasps the handrail 5 to lift the support plate 4. During the lifting of the support plate 4, the packaging belt will be in an inclined state. In the inclined state, the particles inside the packaging bag will continue to flow into the interior of the storage channel 3 through the notch 31. The discharge bag is made of flexible material. The baffles 42 on both sides of the support plate 4 will guide the packaging bag to avoid the packaging bag from tipping over to the sides of the support plate 4 as much as possible, thereby increasing the safety of the packaging bag placement. With the support of the support plate 4, during the process of tipping over the plastic particles, the staff does not need to hold the packaging bag all the time, nor does they need to pull the packaging bag up all the time. This can reduce the workload of the staff, thereby saving a lot of manpower, ensuring the work efficiency of the staff, and has strong practicality.

[0028] Among them, a boss 41 is arranged above the support plate 4, and the boss 41 is arranged in multiple groups. Both sides of the multiple groups of bosses 41 are fitted with the baffle 42. Since the packaging bag is made of elastic material, when the plastic particles in the packaging bag are reduced, the bottom of the packaging bag will be sunken between the multiple bosses 41, so that the packaging bag will not slide on the surface of the support plate 4, thereby increasing the stability of the packaging bag placed on the surface of the support plate 4.

[0029] Preferably, the surface of the handrail 5 is provided with anti-skid patterns 51, and the anti-skid patterns 51 are arranged crosswise. When the staff lifts the handrail 5, they need to grasp the surface of the handrail 5, and the handrail 5 increases the friction with the palm of the staff through the anti-skid patterns 51 arranged crosswise on the surface, which is not easy to slip and is convenient for the staff to exert force.

[0030] Specifically, the support assembly 6 includes a first support column 61 intersecting with the material storage channel 3, a bracket 65 is arranged below the support plate 4, a second support column 62 is rotatably sleeved on the surface of the bracket 65, a buckle 63 is arranged between one end of the second support column 62 and the first support column 61, and a pull rod 64 is hingedly connected to one side of the first support column 61 close to the material storage channel 3, and one end of the pull rod 64 is hingedly connected to the outer wall of the material storage channel 3;

[0031] The material storage channel 3 supports the bracket 65 through the first support column 61 and the second support column 62, and the bracket 65 supports the bottom of the support plate 4. The first support column 61 and the second support column 62 are rotated through the buckle 63, and the angle between the first support column 61 and the second support column 62 is controlled by the buckle 63 to control the height of the bracket 65. The height of the bracket 65 is different, and the supporting angle of the support plate 4 is different, which is convenient for placing the packaging bag on the surface of the support plate 4. The pull rod 64 is composed of two connecting tubes that are slidably connected, and a tension spring is installed inside one of the connecting tubes, and one side of the tension spring is fixed to one end of the other connecting tube. The pull rod 64 pulls the first support column 61 to move the first support column 61 close to the material storage channel 3, thereby increasing the stability of the first support column 61 and the second support column 62 in supporting the bracket 65.

[0032] More specifically, one end of the first support column 61 is fixedly connected to a swivel 611, one end of the second support column 62 is fixedly connected to a collar 621, the collar 621 is located inside the swivel 611, and the swivel 611 and the collar 621 are on the same axis, and the buckle 63 is located inside the swivel 611 and the collar 621;

[0033] The first support column 61 and the swivel 611 are integrally connected, and the sleeve 621 and the second support column 62 are integrally connected. The swivel 611 and the sleeve 621 rotate along the surface of the buckle 63 to increase the stability of the connection structure between the first support column 61 and the second support column 62.

[0034] Further in the implementation process, the buckle 63 includes a shell 631 fixedly connected to the inner wall of the collar 621, a return spring 634 is arranged at the axis of the shell 631, and toothed rings 632 are attached to both sides of the return spring 634. Two groups of toothed rings 632 are located inside the shell 631 and slide, and a guide rod 633 is fixedly connected to the side of the two groups of toothed rings 632 away from each other. The ends of the two groups of guide rods 633 away from each other pass through the rotating ring 611 and contact the outside, and the outer wall of the toothed ring 632 is slidably engaged with the inner wall of the rotating ring 611;

[0035] When the first support column 61 and the second support column 62 need to rotate, the staff presses the two sets of guide rods 633, and the guide rods 633 squeeze the toothed ring 632 to slide toward the inside of the outer shell 631, so that the toothed ring 632 is separated from the first support column 61. The first support column 61 pulls the pull rod 64 to increase the height of the bracket 65. After determining the height of the bracket 65, the staff releases the guide rod 633, and the reset spring 634 squeezes the toothed rings 632 on both sides. The two sets of toothed rings 632 are inserted into the interior of the ring 621. The interior of the ring 621 is fixedly engaged with the outer surface of the toothed ring 632, so that the rotation angle between the first support column 61 and the second support column 62 is determined, and the height of the bracket 65 is stabilized.

[0036] The implementation principle of a plastic film blowing machine in the embodiment of the present application is as follows: when it is necessary to feed the film blowing machine body 1 during use, the staff can rotate the support assembly 6, and the support assembly 6 supports the support plate 4 to keep the support plate 4 horizontal. Then the staff will place the packaging bag filled with plastic particles on the top of the support plate 4, and point the opening of the packaging bag toward the material storage channel 3, and the plastic particles in the material storage channel 3 will flow into the interior of the film blowing machine body 1 through the feeding pipe 2, so that the film blowing machine body 1 blows the plastic. When a part of the plastic in the packaging bag can flow out, the staff will hold the handrail 5 to support the support plate 4 is lifted up. When the support plate 4 is lifted up, the packaging belt will be in an inclined state. In the inclined state, the particles inside the packaging bag will continue to flow into the interior of the storage channel 3 through the notch 31. The discharge bag is made of flexible material. The baffles 42 on both sides of the support plate 4 will guide the packaging bag to avoid the packaging bag from tipping over to the two sides of the support plate 4 as much as possible, thereby increasing the safety of the packaging bag placement. With the support of the support plate 4, during the process of tipping over the plastic particles, the staff does not need to hold the packaging bag all the time, nor does it need to lift the packaging bag all the time, so that the workload of the staff can be reduced, thereby saving a lot of manpower, ensuring the work efficiency of the staff, and having strong practicality.
