Description

Technical Field

[0001] This utility model relates to plastic blown film equipment, specifically, to a PE plastic blown film machine. Background Technology

[0002] A plastic blown film machine is a device that heats and melts plastic particles and then blows them into a thin film. There are many types of blown film machines, including PE, POF, etc. These films are widely used in many fields according to their different materials and properties. They are suitable for various high-end film packaging, plastic bag films, protective films, etc. Due to their good barrier properties, freshness preservation, moisture protection, frost protection, oxygen barrier, and oil resistance, these films can be widely used for light and heavy packaging, such as various fresh fruits, meat products, pickles, fresh milk, liquid beverages, and pharmaceutical products.

[0003] Because plastic granules vary in size, larger granules are not easily melted during heating, resulting in uneven thickness of the extruded film. Since existing blown film equipment does not have a filtration function, people use filter plates to screen the granules to prevent uneven film thickness. For example, Chinese utility model patent with announcement number CN221937275U discloses a blown film equipment for preparing PE packaging bags.

[0004] However, in actual use, it is found that when plastic granules are screened through the filter plate, larger granules may get stuck on the filter plate. Furthermore, when the screened granules are poured back into the mixing tank for heating, the filter plate needs to be removed, which wastes the time of the blowing process. The cumbersome operation process can easily reduce the processing efficiency. How to invent a blowing device to improve these problems has become an urgent problem for those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a PE plastic blown film machine, which aims to solve the problem that larger particles may get stuck on the filter plate, and that the filter plate needs to be removed when the screened particles are poured back into the mixing tank for heating.

[0022] Example, refer to Figures 1-5 A PE plastic blown film machine includes a blown film chamber 1 and a screening box 5;

[0023] A blown film machine 2 and a mixing tank 3 are connected to the blown film chamber 1. The mixing tank 3 is connected to the blown film machine 2. A heating plate 4 is installed on one side of the mixing tank 3. A screening box 5 is fixed on the mixing tank 3. A collection box 6 and several cylinders 11 are installed on the screening box 5. A rotating shaft 18 is connected inside the screening box 5. An adjusting plate 7 is fixedly connected to the rotating shaft 18. A screen 8 is fixedly connected to the adjusting plate 7. Several ear plates 17 are slidably connected to the side of the adjusting plate 7 near the mixing tank 3. The output end of the cylinder 11 is rotatably connected to the ear plate 17. Several sliding rods 13 are slidably connected inside the adjusting plate 7. A cleaning plate 15 is fixedly connected between the sliding rods 13. The cleaning plate 15 is in contact with the screen 8. An elastic component 14 is connected between one end of the sliding rod 13 and the adjusting plate 7.

[0024] Furthermore, a door panel 9 is provided on one side of the screening box 5, and a bevel is machined on the door panel 9, with the opening of the collection box 6 corresponding to the door panel 9.

[0025] It should be noted that by setting a door panel 9 and an inclined surface on one side of the screening box 5, the efficiency of particles entering the collection box 6 can be improved when the screen 8 is feeding, which provides convenience for people to collect particles.

[0026] Furthermore, a number of screws 10 are rotatably connected to one side of the screening box 5. The screws 10 are symmetrically arranged, and a connector is fixed to one end of the collection box 6. The screws 10 are threadedly connected to the connector.

[0027] It should be noted that by setting a screw 10 on one side of the screening box 5 and connecting it to the collection box 6, the stability of the collection box 6 on the side of the screening box 5 can be improved, making it easier for people to collect the screened particles.

[0028] Furthermore, a feeding hopper 12 is fixedly connected to the side of the screening box 5 near the mixing tank 3. Grooves are opened on both sides of the feeding hopper 12, and the cylinder 11 is fixed in the groove.

[0029] It should be noted that by setting a feeding hopper 12 at one end of the screening barrel, the screened particles can be concentrated and fall into the mixing barrel 3. The groove opened facilitates the engagement connection with the cylinder 11, which improves the stability of the feeding hopper 12.

[0030] Furthermore, the adjusting plate 7 has symmetrically opened grooves 16 inside, and the sliding rods 13 are symmetrically arranged inside the grooves, with connecting rods fixed between the sliding rods 13.

[0031] It should be noted that by setting a groove 16 inside the adjusting plate 7 to guide the sliding direction of the slide rod 13, the stability of the slide rod 13 during the sliding process can be improved, making it easier for the slide rod 13 to drive the cleaning plate 15 to clean the particles on the screen 8.

[0032] Furthermore, the cylinder 11 and the ear plate 17 are symmetrically arranged on both sides of the adjusting plate 7, and the cylinder 11 and the ear plate 17 are arranged longitudinally parallel.

[0033] It should be noted that by setting a cylinder 11 at the bottom of the adjusting plate 7 and rotating it with the ear plate 17, the angle of the adjusting plate 7 inside the screening box 5 can be controlled, making it convenient for people to pour the screened particles into the collection box 6.

[0034] The working principle of this PE plastic blown film machine is as follows: During operation, plastic granules are directly poured into the screening box 5. After being filtered through the screen 8, granules of similar size fall directly into the mixing tank 3 via the hopper 12. After being heated by the heating plate 4 and stirred by the mixing tank 3, the plastic film is extruded through the blown film chamber 1 and the blown film machine 2. After the blown film operation is completed, the door panel 9 is opened, and the cylinder 11 installed inside the screening box 5 is activated. Under the push of the cylinder 11, the ear plate 17 slides on the adjusting plate 7 in the direction of the cylinder 11, causing the rotating shaft 18 at one end of the adjusting plate 7 to rotate inside the screening box 5. This causes the adjusting plate 7 to rotate the screen 8 at a suitable angle. Once the adjusting plate 7 has rotated to the appropriate angle, the particles will pass through the door plate 9 along the angle of the screen 8 and fall into the collection box 6. Under the action of the elastic component 14, the slide rod 13 will be pushed out of the slide groove 16. At this time, the cleaning plate 15, which is fixedly connected to the slide rod 13, will clean the particles stuck on the screen 8, so that the particles will pop out of the screen 8 and slide into the collection box 6 together, thereby cleaning the screen 8. After the collection box 6 is full of particles, the screw 10 on one side of the screen box 5 is rotated to separate the collection box 6 from the screen box 5, so that the particles can be directly poured into the mixing tank 3 for film blowing.

[0035] It should be noted that the specific model and specifications of the cylinder need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
