Description

Technical Field

[0001] The utility model relates to the technical field of cotton cleaning equipment in the cotton spinning industry, in particular to a fully sealed pipe joint device for a cotton plucker. Background Art

[0002] In the existing A002 plucking machine used in the textile industry's cotton blowroom process, the plucking trolley rotates in a circular track with its inner end centered on a central column and its outer end circulates along a circular track. The plucking trolley then grabs raw cotton from a circular silo. The cotton then flows through the cotton delivery duct into a tin-iron suction duct mounted on the central column, where it is drawn by a front exhaust fan and flows into the next stage of the process. In production, the tin-iron suction duct mounted on the plucking trolley rotates with the plucking trolley, while the tin-iron delivery duct mounted above the central column is stationary. The suction duct is inserted vertically into the delivery duct (the suction duct's diameter is slightly smaller than the delivery duct's), rotating without contact with the delivery duct. As the wheels of the trolleys gradually wear out during production, the position of the wheel ends of the cotton-grabbing trolley is lowered, causing the cotton-grabbing trolley to tilt and the cotton suction pipe to tilt. The cotton suction pipe inserted in the cotton delivery pipe is not vertical, the cotton suction pipe and the cotton delivery pipe are not concentric, and the two tin pipes rub against each other, causing damage; at the same time, the tin-made cotton suction pipe and the cotton delivery pipe constantly collide and contact intermittently, which will produce sparks and cause a fire hazard; and after repeated friction, the difference in diameter between the cotton suction pipe and the cotton delivery pipe gradually becomes larger, the gap between the pipes is large and not sealed, and air flow is filled in from the gap, resulting in low air flow pressure in the trolley, poor raw material suction, and a large number of cotton knots rubbed against the raw cotton and the pipe, which seriously affect product quality. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the purpose of the invention of this utility model is to provide a fully sealed pipe joint device for a cotton plucking machine to solve the problems of the cotton conveying pipe and the cotton suction pipe being out of center due to wear of the trolley wheels, the pipes rubbing against each other and being damaged, the gaps becoming larger and leaking air, and the cotton suction being poor, so as to ensure production safety and improve product quality.

[0004] To achieve the above-mentioned purpose, the utility model includes a cotton picking trolley, a cotton suction pipe, a cotton delivery pipe, a telescopic pipe, and a center column; the outlet end of the cotton picking trolley is connected to the telescopic pipe via the cotton suction pipe, and the telescopic pipe is connected to the cotton delivery pipe via a fully sealed pipe joint;

[0005] 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 fixing bolts sequentially connect the fixed plate interface, the sealing ring, the movable joint, and the supporting circular plate together;

[0006] The outer diameter of the movable joint is smaller than the inner diameter of the sealing ring and 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 in the sealing ring through the telescopic tube and the movable joint tube in sequence.

[0007] The cotton picking trolley moves in a circle along the central column.

[0008] Furthermore, the fixed tube is provided with a center hole of the fixed plate, and the circumference of the fixed tube is provided with a fixed plate connecting hole; the sealing ring is provided with a center hole of the sealing ring, and the circumference of the sealing ring is provided with a sealing ring connecting hole; the supporting circular plate is provided with a center hole of the supporting circular plate, and the circumference of the supporting circular plate is provided with a supporting circular plate connecting hole; the movable joint is provided with a center hole of the movable joint; the fixing bolts pass through the fixed plate connecting hole, the sealing ring connecting hole, and the supporting circular plate connecting hole in sequence to connect the fixed plate interface, the sealing ring, the movable joint, and the supporting circular plate together.

[0009] Furthermore, the inner diameters of the central hole of the fixed plate, the central hole of the supporting circular plate, and the central hole of the movable joint are the same.

[0010] Furthermore, the fixing plate connection holes, the sealing ring connection holes, and the supporting circular plate connection holes are evenly distributed and matched.

[0011] Furthermore, the telescopic tube is a PVC rubber telescopic hose or a PVC steel wire corrugated hose.

[0012] Furthermore, the sealing ring is made of rubber material.

[0013] Furthermore, the cotton conveying pipeline 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 pipeline is perpendicular to the center of the cotton conveying pipeline.

[0014] Compared with the existing technology, the present invention integrates a fixed plate interface, sealing ring, supporting circular plate, and movable joint. The movable joint flexibly rotates between the fixed plate interface and the supporting circular plate, ensuring seamless and airtight connection between the cotton delivery and suction pipes, ensuring smooth material intake. When wheel wear causes the diameter to change, and the suction pipe and the movable joint pipe are not perpendicular, the telescopic tube can automatically expand and contract, ensuring that the pipe through which the raw material passes remains fully enclosed. This application overcomes fire hazards, reduces the generation of neps, and effectively improves the quality of raw material opening. BRIEF DESCRIPTION OF THE DRAWINGS

The thickness of the movable joint 4 is smaller than the thickness of the sealing ring 2. The cotton suction pipe 15 drives the movable joint 4 to rotate flexibly within the sealing ring 2 through the telescopic tube 5 and the movable joint pipe 14 in sequence, ensuring that the pipe is always in a fully enclosed state. The movable joint pipe 14 is concentrically connected to the movable joint center hole 13 as a whole. The movable joint pipe 14 is inserted from 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 sealing ring center hole 9 of the sealing ring 2 between the fixed plate interface 1 and the supporting circular plate 3.
