Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to an energy-saving spiral stirring plastic wire drawing machine. Background Art

[0002] Plastic wire drawing machine is a special set of equipment used in the plastic products industry. Its main function is to heat, melt and stretch plastic raw materials into filaments. Through the rotation of the spiral, the plastic particles are driven to move along the spiral path to achieve comprehensive mixing. This mixing method ensures that in the subsequent processing, the composition and color of the plastic raw materials are more uniform, thereby improving the consistency of product quality and reducing the scrap rate.

[0003] After searching, a Chinese patent with application number CN201821818620.6 discloses a plastic wire drawing machine. Long-term use will cause the filter box to be filled with impurities, affecting the normal filtering function. In severe cases, the filter box will even be blocked, resulting in production interruption and reduced work efficiency. Therefore, it is necessary to clean the inside of the filter box regularly. The filter box is generally fixedly connected below the feed port, and it is difficult to disassemble and clean it, which is time-consuming and laborious, causing inconvenience to the workers in the cleaning work. Therefore, the problem of the filter box being inconvenient to clean and reducing production efficiency is solved.

Too many motors running at the same time may easily lead to excessive burden on the equipment, resulting in malfunctions, and easily increase energy consumption of the equipment, which is not conducive to energy saving and increases the economic cost of the production process.

[0037] Working principle: When in use, the plastic raw material is put into the plastic heating barrel 1 through the feed pipe 27, and then the motor 3 is turned on, so that the output end of the motor 3 drives the synchronous wheel 4 and the eccentric wheel 5 to rotate at the same time. When the eccentric wheel 5 rotates, it drives the two push rods 7 outside the mounting column 6 to move left and right with the rotation of the eccentric wheel 5. When moving to the left, the push rod 7 pushes the connecting rod 8 to move left, so that the connecting rod 8 pulls the sieve plate 2 to move left, and then when the mounting column 6 in the eccentric wheel 5 rotates to the right, it indirectly drives The sieve plate 2 moves to the right, so that the sieve plate 2 is easy to shake and screen, which is beneficial to screening the plastic raw materials put in.

Then the exhaust gas will pass through the activated carbon plate 22, and the adsorption filtration of the activated carbon plate 22 will facilitate the filtered gas to be discharged to the exhaust pipe 18.
