Description

Technical Field

[0001] This invention relates to the field of cotton cleaning equipment technology in the cotton spinning industry, specifically a fully sealed pipe joint device for a cotton grabber. Background Technology

[0002] In existing technology, on the A002 type cotton grabbing machine in the cotton cleaning process of the textile industry, one end of the cotton grabbing trolley rotates cyclically around a central column, while the other end rotates along a circular track. The rotating trolley grabs raw cotton from a circular cotton bin. The grabbed raw cotton is then conveyed through a cotton conveying pipe into a galvanized iron suction pipe placed on the central column, and then drawn into the next process by a front-end exhaust fan. In production practice, the galvanized iron suction pipe fixed to the cotton grabbing trolley rotates with the trolley, while the galvanized iron conveying pipe above the central column pipe remains stationary. The suction pipe is vertically inserted into the conveying pipe (its diameter is slightly smaller than the conveying pipe's diameter), rotating without contact with the conveying pipe. As the wheels of the trolley wear down during production, the position of the wheels on the cotton-grabbing trolley decreases, causing the trolley to tilt and the suction pipe to tilt as well. The suction pipe inserted into the conveying pipe is no longer vertical, and the suction pipe and conveying pipe are not concentric. The two galvanized iron pipes rub against each other, causing damage. At the same time, the intermittent collisions between the galvanized iron suction pipe and the conveying pipe generate sparks, creating a fire hazard. After repeated friction, the diameter difference between the suction pipe and the conveying pipe gradually increases, resulting in large gaps between the pipes and a lack of sealing. Airflow enters through these gaps, leading to low airflow pressure inside the trolley, poor raw material suction, and the friction between the raw cotton and the pipes, producing a large number of cotton knots, which seriously affects product quality. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, the purpose of this invention is to provide a fully sealed pipe joint device for a cotton grabber, so as to solve the problems of misalignment between the cotton conveying pipe and the cotton suction pipe caused by wear of the trolley wheels, mutual friction and damage of the pipes, enlarged gaps and air leakage, and poor cotton suction, thereby ensuring production safety and improving product quality.

[0004] To achieve the above-mentioned objectives, the present invention includes a cotton-grabbing trolley, a cotton-suction pipe, a cotton-transporting pipe, a telescopic pipe, and a central column; the outlet end of the cotton-grabbing trolley is connected to the telescopic pipe via the cotton-suction pipe, and the telescopic pipe is connected to the cotton-transporting pipe via a fully sealed pipe joint. The fully sealed pipe joint includes a fixed plate interface, a sealing ring, a supporting circular plate, a movable joint, and a fixed pipe; the fixed plate interface is connected to the fixed pipe of the cotton conveying pipe, the movable joint is connected to the telescopic pipe via the movable joint pipe, the movable joint pipe passes through the central circular hole of the supporting circular plate and is connected to the movable joint, and a sealing ring is provided between the fixed plate interface and the supporting circular plate; the fixed bolts sequentially connect the fixed plate interface, the sealing ring, the movable joint, and the supporting circular plate together; The outer diameter of the movable joint is smaller than the inner diameter of the sealing ring but larger than the inner diameter of the supporting circular plate. The thickness of the movable joint is smaller than the thickness of the sealing ring. The cotton suction pipe drives the movable joint to rotate inside the sealing ring through the telescopic pipe and the movable joint pipe in sequence. The cotton-grabbing trolley moves in a circular motion along the central column.

[0005] Furthermore, the fixed tube has a central hole for the fixed plate, and the fixed tube has connecting holes for the fixed plate around its circumference; the sealing ring has a central hole for the sealing ring, and the sealing ring has connecting holes for the sealing ring around its circumference; the supporting circular plate has a central hole for the supporting circular plate, and the supporting circular plate has connecting holes for the supporting circular plate around its circumference; the movable joint has a central hole for the movable joint; the fixing bolts pass through the connecting holes for the fixed plate, the connecting holes for the sealing ring, and the connecting holes for the supporting circular plate in sequence to connect the fixed plate interface, the sealing ring, the movable joint, and the supporting circular plate together.

[0006] Furthermore, the inner diameters of the center holes of the fixed plate, the support circular plate, and the movable joint are the same.

[0007] Furthermore, the connecting holes of the fixing plate, the connecting holes of the sealing ring, and the connecting holes of the supporting circular plate are evenly distributed and matched.

[0008] Furthermore, the telescopic tube is a PVC rubber telescopic hose or a PVC steel wire corrugated hose.

[0009] Furthermore, the sealing ring is made of rubber material.

[0010] Furthermore, the cotton conveying pipe is located above the central column, the wheels of the cotton grabbing trolley move in a circular motion along the central column on a circular track, and the center of the cotton suction pipe is perpendicular to the center of the cotton conveying pipe.

[0011] Compared with existing technologies, the fixed plate interface, sealing ring, supporting circular plate, and movable joint of this invention are integrated into one unit. The movable joint rotates flexibly between the fixed plate interface and the supporting circular plate, ensuring a seamless and airtight connection between the cotton conveying pipe and the cotton suction pipe, guaranteeing smooth raw material intake. When wheel wear causes a change in diameter and the cotton suction pipe is not perpendicular to the movable joint pipe, the telescopic pipe can automatically expand and contract, ensuring that the pipe through which the raw material passes is always in a fully sealed state. This application overcomes fire hazards, reduces cotton knot formation, and effectively improves the quality of raw material opening. Attached Figure Description

The thickness of the movable joint 4 is smaller than the thickness of the sealing ring 2. The cotton suction pipe 15, via the telescopic pipe 5 and the movable joint pipe 14, drives the movable joint 4 to rotate flexibly within the sealing ring 2, ensuring that the pipe is always in a fully sealed state. The movable joint pipe 14 is concentrically connected to the movable joint center hole 13. The movable joint pipe 14 is inserted below the center hole 11 of the supporting circular plate and connected to the movable joint 4. The movable joint 4 is clamped in the center hole 9 of the sealing ring 2 between the fixed plate interface 1 and the supporting circular plate 3. In this embodiment, the outer diameter of the movable joint 4 is 360 mm and the thickness is 4 mm. The inner diameter of the sealing ring 2 is 400 mm and the thickness is 6 mm.

[0019] The cotton-grabbing trolley 17 moves in a circular motion along the central column 16.

[0020] Preferably, the fixing tube 6 has a fixing plate center hole 7 and a fixing plate connecting hole 8 around its circumference; the sealing ring 2 has a sealing ring center hole 9 and a sealing ring connecting hole 10 around its circumference; the supporting circular plate 3 has a supporting circular plate center hole 11 and a supporting circular plate connecting hole 12 around its circumference; the movable joint 4 has a movable joint center hole 13; the fixing bolt passes through the fixing plate connecting hole 8, the sealing ring connecting hole 10, and the supporting circular plate connecting hole 12 in sequence to connect the fixing plate interface 1, the sealing ring 2, the movable joint 4, and the supporting circular plate 3 together. The inner diameters of the fixing plate center hole 7, the supporting circular plate center hole 11, and the movable joint center hole 13 are the same. The fixed plate connection hole 8, the sealing ring connection hole 10, and the support round plate connection hole 12 are evenly distributed and matched. In this embodiment, the fixed plate connection hole 8, the sealing ring connection hole 10, and the support round plate connection hole 12 are all arranged in four sets. The four sets of fixing bolts pass through the fixed plate connection hole 8, the sealing ring connection hole 10, and the support round plate connection hole 12 in sequence to connect the fixed plate interface 1, the sealing ring 2, the movable joint 4, and the support round plate 3 together. Before connection, the movable joint 4 is placed between the sealing ring 2 and the support round plate 3.

The cotton suction pipe 15 rotates with the cotton-grabbing trolley 17, driving the telescopic pipe 5 to rotate. The telescopic pipe 5 drives the movable joint 4 to rotate flexibly within the sealing ring 2. The fixed plate interface 1, the sealing ring 2, and the supporting circular plate 3 seal the movable joint 4, ensuring a leak-proof seal between the rotating cotton suction pipe 15 and the cotton conveying pipe 19. When the wheel 18 wears down due to long-term operation, causing the cotton suction pipe 15 to tilt, the telescopic pipe 5 automatically deforms. The raw material sequentially passes through the always-sealed cotton suction pipe 15, telescopic pipe 5, movable joint pipe 14, and cotton conveying pipe 19 into the next stage of equipment, effectively eliminating fire and quality hazards.
