Description

TECHNICAL FIELD

[0002] At present, setting machines are often used in the process of the textile industry, and the setting machine is a machine used for industrial manufacturing setting. The setting machine can be divided into shoe upper setting machine, sock setting machine and fabric setting machine according to types.

[0003] During the heating and setting process of the setting machine on the cloth, the heating air flow will blow part of the lint attached to the cloth away from the cloth surface and mix into the circulating air. The lint will enter the fan heat exchanger and other equipment of the exhaust system, causing pipeline blockage. However, the exhaust pipe will absorb part of the silicon oil on the cloth during the working process, so that the lint in the exhaust pipe will stick to the inner wall of the exhaust pipe, which makes it difficult for the workers to clean it thoroughly. The setting machine air duct lint cleaning assembly disclosed in the authorized announcement No. CN217988689U facilitates the operation of the workers. The lint sucked into the air inlet pipe can be blocked by the filter screen, so that the lint is not easy to stick to the inner wall of the branch pipe. The cleaning frequency of the workers on the branch pipe can be reduced, and the working efficiency is improved.

9. A duct cleaning device for a stenter according to claim 8, characterized in that, The handle assembly (8) includes a limiting block (801) fixedly connected to one end of the push threaded rod (701) extending to the outside of the fixed plate (301), a connecting sleeve (802) sleeved on the outer surface of the limiting block (801), a connecting round block (803) fixedly connected to one end of the connecting sleeve (802), a positioning round groove (805) opened at the other end of the connecting sleeve (802), a sealing ring (806) fixedly connected to the inside of the positioning round groove (805), a connecting round groove (804) opened in the middle of the sealing plate (303), a limiting hole (807) opened at one end of the positioning round groove (805), a limiting groove (808) opened at one end of the limiting hole (807), and a cavity (809) opened at one end of the limiting groove (808). The cross-sectional profile inside the limiting groove (808) is adapted to the cross-sectional profile outside the limiting block (801), and the limiting block (801) is set as a square block.

10. A cleaning method for a stenter air duct cleaning device according to any one of claims 1 to 9, characterized in that, The specific steps of the cleaning method are as follows: Step 1: By inserting the plate assembly (3) into the mounting slot (203) on the frame assembly (2), the connecting block (803) is rotated. The connecting block (803) drives the limiting block (801) and its pushing threaded rod (701) to rotate, which in turn drives the double-headed threaded rod (401) to rotate. The rotating double-headed threaded rod (401) drives the two driving blocks (402) to move closer to each other, thereby causing the end of the opening rod (403) to retract, which in turn drives the two filter components (5) to move away from each other, so that the filter components (5) open inside the air duct body (1). The rotating pushing threaded rod (701) drives the moving block (702) to move closer to each other. 02) Move, the moving block (702) drives the pushing block (703) to move, the pushing block (703) approaches the handle assembly (8), the pushing block (703) squeezes the positive push block (705), so that the locking block (707) and the locking groove (708) are engaged, and the sealing gasket (304) is used to make full contact between the end face of the sealing plate (303) and the frame plate (201) to achieve sealing. Then the connecting round block (803) moves inward, so that the connecting sleeve (802) and the connecting round groove (804) are inserted, thereby squeezing the sealing ring (806) to seal the sealing plate (303); Step 2: Use the filter screen (503) that opens inside the air duct body (1) to intercept lint; Step 3: Move the connecting block (803) outward to separate the connecting sleeve (802) from the connecting groove (804) until the limiting groove (808) engages with the limiting block (801). Then reverse the connecting block (803) so that the connecting block (803) drives the push thread rod (701) and its double-headed thread rod (401) to reverse, so that the filter assembly (5) retracts into the U-shaped frame (302). At the same time, the push block (703) moves away from the handle assembly (8), thereby driving the push block (703) to squeeze the push block (706), so that the pressure block (704) moves in the opposite direction, so that the locking block (707) separates from the locking groove (708). At this time, the plate assembly (3) can be moved outward to remove the plate assembly (3) and its filter assembly (5), so that the filter screen (503) can be cleaned, thereby reducing the number of times the air duct body (1) is cleaned.
