Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, specifically relating to a dust collection cover for textiles. Background Technology

[0002] During textile production and processing, pollutants such as lint, fiber debris, and dust can easily spread in the air, polluting the working environment and potentially causing occupational health problems and equipment malfunctions (such as yarn entanglement and sensor blockage). Existing textile workshops generally use dust collection hood systems to collect pollutants in a targeted manner, but traditional dust collection hood designs have significant functional defects and are difficult to meet the needs of refined production.

[0003] Traditional textile dust collection hoods typically employ a fixed, rigid structure for their suction heads, which are rigidly connected to the ductwork via a metal bracket or achieve limited angle adjustment via a simple universal joint. This design suffers from poor adjustment flexibility, resulting in lengthy adjustments during multi-station switching or process adjustments, leading to increased production downtime. Furthermore, its stability is weak; the universal joint adjustment mechanism relies on friction or a single bolt for locking, making the suction head prone to angular displacement under equipment vibration or airflow impact. This causes the suction port to deviate from the center of the pollution source, increasing the escape rate of lint and thus reducing suction efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a textile dust cover to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A dust hood for textiles includes a vertical tube, a connector rotatably connected to the lower side of the vertical tube, a support mechanism installed on the right side of the connector, a dust hood head connected to the right side of the support mechanism, a dust suction pipe installed on the upper side of the support mechanism, and the left and right ends of the dust suction pipe being connected to the connector and the dust hood head pipe respectively.

[0007] The support mechanism includes a bracket, with two sets of support rods symmetrically hinged at its left and right ends. Each set of support rods consists of two rods arranged parallel to each other vertically. The left end of the left support rod is hinged to the connector, and the right end of the right support rod is hinged to the dust extraction hood. Two hydraulic cylinders are symmetrically hinged to the lower side of the bracket. Each hydraulic cylinder has an oil inlet and an oil return port connected to its upper side. A piston rod is mounted inside the hydraulic cylinder, and the upper end of the piston rod is connected to the corresponding support rod. An oil reservoir is fixed to the outside of the vertical pipe, and four oil pipes are connected to the lower side of the oil reservoir. The four oil pipes are respectively connected to two oil inlets and two oil return ports. A valve assembly for controlling the on / off state is connected to the middle of each oil pipe.

[0008] The valve assembly includes a valve body fixed to the bracket. A circular cavity is formed inside the valve body. Four sets of connecting pipes are symmetrically connected to the upper and lower sides of the valve body, spaced apart from each other. The upper connecting pipes are connected to the four oil pipes respectively, and the lower connecting pipes are connected to the two oil inlets and the oil return pipes respectively. Four plugs matching the connecting pipes and the circular cavity are installed at intervals on the inner side of the circular cavity. A pull rod fixedly connected to the plugs is slidably installed on the inner side of the valve body. A return spring connected to the right side of the plug on the right side is connected to the right side of the valve body. A control component for controlling the movement of the pull rod is installed on the upper side of the support mechanism.

[0009] A handle is fixed to the upper side of the vacuum cleaner head, and a control handle is hinged to the lower side of the handle. A first fixing block is fixed to the side of the handle, and a second fixing block is installed on the right side of the valve body, spaced apart from the pull rod. A conduit is connected between the first fixing block and the second fixing block, and a pull wire is slidably connected to the inside of the conduit. One end of the pull wire is driven to the control handle, and the other end is driven to the pull rod.

[0010] A support spring is sleeved on the outside of the piston rod, and the upper and lower ends of the support spring are respectively connected to the oil cylinder and the support rod.

[0011] A friction disc is fixed to the lower side of the vertical pipe, and an elastic telescopic rod is fixed to the outside of the connector. The output end of the elastic telescopic rod is connected to a friction block that abuts against the friction disc.

[0012] The bracket has a perforated hole on its upper side.

[0013] The coordinated operation of the valve assembly, hydraulic cylinder, piston rod, and support rod allows operators to flexibly adjust the direction and position of the dust collection head, enabling it to more effectively capture dust, improve dust collection efficiency, reduce dust concentration in the workshop, and improve the working environment. Simultaneously, the cooperation between the valve assembly, hydraulic cylinder, and piston rod allows for quick adjustment and fixation of the dust collection head, while minimizing angular displacement during fixation, ensuring production continuity and stability. The design of the left-right moving block and cavity makes the valve easy to control overall, while also making the valve assembly structure simple and reliable, helping to reduce its use and maintenance costs. A handle provides convenient gripping for operators when moving the dust collection head. The combination of the tube, pull cable, and control handle allows operators to easily control the valve assembly by pinching the control handle, improving the ease of use of the dust hood. The support spring provides auxiliary support to the support rod when adjusting the dust hood head, making it easier for operators to adjust the position of the dust hood head and improving its usability. The friction disc, friction block, and elastic support rod work together to increase the rotational friction between the connector and the vertical tube, which helps increase the lateral stability of the dust hood head without affecting its lateral movement. The perforated holes reduce the weight of the support mechanism, thereby reducing the load on the support rod and further extending the service life of the equipment. Attached Figure Description

[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-5 As shown, a textile dust hood includes a vertical tube 1, a connector 2 rotatably connected to the lower side of the vertical tube 1, a support mechanism installed on the right side of the connector 2, a dust hood head 3 connected to the right side of the support mechanism, a dust suction pipe 4 installed on the upper side of the support mechanism, and the left and right ends of the dust suction pipe 4 connected to the connector 2 and the dust hood head 3 respectively.

[0023] The support mechanism includes a bracket 5. Two sets of support rods 6 are symmetrically hinged at the left and right ends of the bracket 5. Each set of support rods 6 consists of two rods that are distributed parallel to each other vertically. The left end of the left support rod 6 is hinged to the connector 2, and the right end of the right support rod 6 is hinged to the dust collection head 3. Two hydraulic cylinders 7 are symmetrically hinged at the lower side of the bracket 5. Each hydraulic cylinder 7 has an oil inlet 8 and an oil return port 9 connected to its upper side. A piston rod 10 is mounted inside the hydraulic cylinder 7. The upper end of the piston rod 10 is connected to the corresponding support rod 6. An oil can 11 is fixed to the outside of the vertical pipe 1. Four oil pipes 12 are connected to the lower side of the oil can 11. The four oil pipes 12 are respectively connected to the two oil inlets 8 and the two oil return ports 9. A valve assembly for controlling the on / off state is connected to the middle of the oil pipes 12.

[0024] In this invention, the vertical pipe 1 is connected to an external vacuuming device. Dust from the vacuum hood 3 is sucked in through the vacuum pipe 4 and collected inside the vacuuming device via the connector 2 and the vertical pipe 1, thus achieving the vacuuming function during the textile process. An oil reservoir 11 is fixed to the outside of the vertical pipe 1. The oil reservoir 11 contains oil, and four oil pipes 12 are connected to the lower side of the oil reservoir 11, respectively connecting to two oil inlets 8 and two oil return ports 9, providing hydraulic oil to the cylinder 7. The cylinder 7 is filled with oil. The connector 2 allows the support mechanism and the vacuum hood 3 to rotate as a whole. When the position of the vacuum hood 3 needs to be moved, simply open the valve assembly. When the oil can flow, the angle between the support rod 6 and the bracket 5 can be adjusted, allowing the vacuum hood 3 to move vertically and horizontally. When the vacuum hood 3 needs to be fixed, simply close the valve, preventing the oil from flowing. At this time, the piston rod 10 and the support rod 6 cannot move, thus fixing the vacuum hood 3.

[0025] The cooperation of the valve assembly, hydraulic cylinder 7, piston rod 10, and support rod 6 allows the operator to flexibly adjust the direction and position of the dust collection head 3, enabling it to capture dust more effectively, improve dust collection efficiency, reduce dust concentration in the workshop, and improve the working environment. At the same time, the cooperation of the valve assembly, hydraulic cylinder 7, and piston rod 10 allows the dust collection head 3 to be quickly adjusted and fixed, and it is not easy for the angle to shift when fixed, ensuring the continuity and stability of production.

[0026] The valve assembly includes a valve body 13 fixed to the bracket 5. A circular cavity 14 is opened inside the valve body 13. Four sets of connecting pipes 15 are symmetrically connected to the upper and lower sides of the valve body 13, with left and right intervals. The upper connecting pipes 15 are connected to four oil pipes 12 respectively, and the lower connecting pipes 15 are connected to two oil inlets 8 and oil return ports 9 respectively. Four plugs 16 that match the connecting pipes 15 and the circular cavity 14 are installed on the left and right sides of the circular cavity 14. A pull rod 17 that is fixedly connected to the plugs 16 is slidably installed on the left and right sides of the valve body 13. A return spring 18 connected to the right side of the plug 16 on the right side is connected to the right side of the valve body 13. A control component for controlling the movement of the pull rod 17 is installed on the upper side of the support mechanism.

[0027] When the lever 17 is not subjected to external force, the return spring 18 causes the block 16 to block all connecting pipes 15, at which point the oil cannot flow, and the position of the support rod 6 is fixed. When it is necessary to adjust the position of the dust hood 3, simply move the lever 17 to the right. At this time, the connecting pipe 15 on the lower side of the valve body 13 can be connected to the connecting pipe 15 on the upper side, and the oil inside the pipe can flow. The design of the left and right moving block 16 and cavity makes the valve easy to control as a whole, and also makes the valve assembly structure simple and reliable, which helps to reduce its use and maintenance costs.

[0028] A handle 19 is fixed to the upper side of the vacuum hood 3, and a control handle 20 is hinged to the lower side of the handle 19. A first fixing block 21 is fixed to the side of the handle 19. A second fixing block 22, spaced apart from the pull rod 17, is installed on the right side of the valve body 13. A conduit 23 is connected between the first fixing block 21 and the second fixing block 22. A pull wire 24 is slidably connected to the inside of the conduit 23. One end of the pull wire 24 is connected to the control handle 20, and the other end is connected to the pull rod 17.

[0029] When the vacuum hood head 3 is moved, the handle 19 makes it easy for the staff to hold it. The cooperation of the conduit 23, pull cord 24 and control handle 20 makes it easy for the staff to control the valve assembly by squeezing the control handle 20, thus improving the ease of use of the vacuum hood.

[0030] A support spring 25 is sleeved on the outside of the piston rod 10. The upper and lower ends of the support spring 25 are respectively connected to the oil cylinder 7 and the support rod 6.

[0031] The support spring 25 can provide auxiliary support to the support rod 6 when adjusting the vacuum hood head 3, making it easier for the operator to adjust the position of the vacuum hood head 3 and improving the ease of use of the vacuum hood.

[0032] A friction disc 26 is fixed to the lower side of the vertical pipe, and an elastic telescopic rod 27 is fixed to the outside of the connector 2. The output end of the elastic telescopic rod 27 is connected to a friction block 28 that abuts against the friction disc 26.

[0033] The friction disc 26, friction block 28 and elastic support rod 6 work together to increase the rotational friction between the connector 2 and the vertical tube 1, which helps to increase the lateral stability of the vacuum hood 3 without affecting its lateral movement.

[0034] The upper side of the bracket 5 has a hollow hole 29.

[0035] The perforated hole 29 reduces the weight of the support mechanism, thereby helping to reduce the load on the support rod 6 and further extend the service life of the equipment.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
