Description

Technical Field

[0001] The present invention relates to the field of material suction and dry material in the injection molding technology of rubber and plastic materials, and particularly to a pulsating switching exhaust mechanism for a material suction and dry material integrated machine. Background Art

[0002] During the injection molding process of rubber and plastic injection products, the main raw materials, rubber and plastic particles, need to go through processes such as drying and feeding. In the prior art, only a feeding machine and a drying machine are used separately, and there is no device that integrates functions such as material suction, drying, and cleaning. To a certain extent, this reduces the practicality of the feeding machine and the drying machine. Users need to purchase a feeding machine and a drying machine separately to solve the problem of automatic feeding of rubber and plastic particles, resulting in high investment costs, large floor space, and significantly reduced production efficiency. Moreover, during the production process, dust impurities in the rubber and plastic particles are extremely likely to block the filter element of the feeding machine and cannot work properly, requiring manual cleaning at regular intervals. In addition, fine dust is discharged into the air in the workshop through the exhaust port of the material suction machine, seriously affecting the environment and the physical and mental health of the staff. Summary of the Invention

[0003] The purpose of the present invention is to provide a pulsating switching exhaust mechanism to solve the above problems, enabling the functions of drying rubber and plastic particles, feeding, and fully automatic cleaning of the filter screen to be carried out fully automatically on one device, improving production efficiency, saving floor space for equipment use, and significantly reducing the user's usage cost.

One end of the main body housing is installed with a first cylinder, the axis of the first cylinder is parallel to the axis of the main body housing, the first piston and the second piston of the first cylinder are sequentially distributed on the axis of the main body housing. There is a first ventilation opening between the first main body housing side plate and the sealing baffle of the main body housing, and the first ventilation opening is communicated with the secondary housing.

The inner wall of the main body housing between the first piston and the second piston is designed with a first sealing opening, and an electromagnetic switch is installed on the outer wall of the main body housing.

[0006] As a further description of the above technical solution:

[0024] Specifically, as Figure 2 shown, an air duct baffle 14 is installed between the inner wall of the auxiliary housing 13 near the first ventilation opening 7 and the outer wall of the main body housing 6. The air duct baffle 14 plays a role in isolating the ventilation opening to prevent the device from failing due to air duct cross-talk.

[0027] Specifically, as Figure 2 shown, a filter pressure regulating device 2 is installed at one end of the outer wall of the main body housing 6 close to the first cylinder 1 through a mounting bracket 3, so as to filter and regulate the compressed air flowing into the device, ensuring that the cleanliness and air pressure of the inflowing air meet the requirements.

[0028] Specifically, as Figure 2 shown, a second cylinder 5 is installed on one side of the main body housing 6 corresponding to the third sealing opening 21. The axis line of the second cylinder 5 is perpendicular to the axis line of the first cylinder 1, facilitating the realization of the functions of pulsating switching exhaust and fully automatic cleaning of the filter screen.

[0029] Working principle: During use, the third ventilation opening 9 and the fourth ventilation opening 10 are respectively connected to the two ventilation openings of the fan, the first ventilation opening 7 and the second ventilation opening 8 are respectively connected to other air ducts, and the electrical control system controls the operation of the first cylinder 1 and the second cylinder 5 through the electromagnetic switch 4, so that the first piston 11 and the second piston 12 are in different position states in the main body housing 6, realizing different connection or closing states between the first ventilation opening 7 and the third ventilation opening 9, the second ventilation opening 8 and the fourth ventilation opening 10, as well as the sealing and opening states of the second cylinder 5, thereby realizing functions such as material suction, drying, and cleaning of the equipment. The frequent and repeated actions of the first cylinder 1 and the second cylinder 5 thus realize the functions of pulsating switching exhaust and fully automatic cleaning of the filter screen.
