Description

Technical Field

[0001] This utility model relates to the technical field of blown film machines, specifically a blown film machine for producing plastic products that prevents material blockage. Background Technology

[0002] With the widespread application of plastic products in packaging, agriculture, daily life and many other fields, the importance of blown film machines as key equipment for producing plastic films is becoming increasingly prominent. Plastic films, with their characteristics of being lightweight, inexpensive, having good barrier properties and flexibility, have become an indispensable material for many product packaging and related applications. However, blown film machines need to heat plastic granules before blowing them into film. During the feeding process, plastic granules tend to accumulate, causing feed blockage and affecting processing efficiency. Furthermore, plastic granules contain some solid impurities that, if not filtered, enter the blown film machine and can easily damage internal components. The presence of impurities may also affect the quality of the plastic film. To solve these problems, a blown film machine for producing plastic products that prevents material blockage is needed.

[0003] An existing blown film machine for plastic product manufacturing cannot prevent material blockage and filter raw materials during operation. Therefore, there is an urgent need for a blown film machine for plastic product manufacturing that can prevent material blockage. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a blown film machine for producing plastic products with anti-clogging properties, so as to solve the problem that existing blown film machines for producing plastic products with anti-clogging properties cannot prevent material blockage and cannot filter raw materials during use.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figure 1-4 A blown film machine for producing plastic products with anti-clogging properties includes a conveying pipe 1, a drive motor 2 installed on the outer wall of the conveying pipe 1, a heating chamber 3 installed on the top of the conveying pipe 1, a feeding chamber 4 installed on the top of the heating chamber 3, a power motor 5 installed on the side wall of the feeding chamber 4, a feeding roller 6 installed on the outer wall of the power motor 5, and a storage bin 7 opened on the outer wall of the feeding roller 6. The feeding bin 4 is movably connected to the feeding roller 6, and the outer wall of the feeding roller 6 is tightly fitted with the inner wall of the feeding bin 4. The feeding roller 6 and the feeding bin 4 form a rotating structure through the power motor 5. The storage bins 7 are arranged in a circular array with the central axis of the feeding roller 6 as the center. Through the arrangement of the feeding bin 4, the power motor 5, the feeding roller 6, and the storage bins 7, when plastic granules are put into the feeding bin 4, the power motor 5 is started to drive the feeding roller 6 to rotate, and the plastic granules will enter the storage bins 7. With the rotation of the feeding roller 6, the plastic granules are quantitatively conveyed, effectively preventing the plastic granules from accumulating and clogging at the bottom of the feeding bin 4.

[0022] Please see Figure 1-4 A blown film machine for producing plastic products with anti-clogging properties is disclosed. A filter sleeve 8 is installed on the top of the feed hopper 4. A positioning rod 9 is installed on the inner wall of the filter sleeve 8. A limit spring 10 is installed on the outer wall of the positioning rod 9. A limit sleeve 11 is installed on the outer wall of the positioning rod 9. A die head 12 is installed on the outer wall of the conveying pipe 1. A limit frame 13 is installed on the top of the die head 12. A fixing frame 14 is installed on the outer wall of the limit frame 13. A limit extrusion plate 15 is installed on the inner wall of the fixing frame 14. An embossing roller 16 is installed on the top of the fixing frame 14. A guide roller 17 is installed on the outer wall of the fixing frame 14. The filter sleeve 8 is conical in shape and is connected to the feed hopper 4 by the limit spring 10. The filter sleeve 8 is telescopically connected to the positioning rod 9, and the positioning rod 9 is threadedly connected to the limiting sleeve 11. The limiting spring 10 is sleeved with the positioning rod 9, and the positioning rod 9 is arranged in a rectangular array with the central axis of the filter sleeve 8 as the center. Through the filter sleeve 8, positioning rod 9, limiting spring 10 and limiting sleeve 11, when plastic particles are put into the filter sleeve 8, the filter sleeve 8 will intercept and filter larger plastic particles or impurities, preventing them from entering the equipment and damaging the parts. At the same time, by pressing the filter sleeve 8, the filter sleeve 8 will vibrate vertically through the elastic force of the limiting spring 10, which will accelerate the feeding efficiency.

[0023] Working Principle: In use, first move the device to the desired position, then feed the plastic granules into the filter sleeve 8. The filter sleeve 8 will intercept and filter larger diameter plastic granules or impurities, preventing them from entering the equipment and damaging components. Simultaneously, pressing the filter sleeve 8 causes it to vibrate vertically via the spring force of the limit spring 10, accelerating the feeding efficiency. When the plastic granules are fed into the feeding hopper 4, the power motor 5 drives the feeding roller 6 to rotate, and the plastic granules enter the storage hopper 7. With the rotation of the feeding roller 6, they are quantitatively conveyed, effectively preventing accumulation and blockage at the bottom of the feeding hopper 4. The plastic granules then enter the heating chamber 3 for heating and melting, and enter the die head 12 through the conveying pipe 1. They are blown up by a blower to form a bubble film, which continues to rise under the support of the limit frame 13 and is then extruded and plasticized by the limit extrusion plate 15. After embossing by the embossing roller 16, they are wound up by the guide roller 17. This completes the device's operation.
