Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic hose production equipment, and in particular, it is a water cloth winding and unwinding device. Background Technology

[0002] In the production of hydraulic hoses, the winding and unwinding of the waterproof cloth is a crucial step. When processing debris, oil, dust, or other impurities remain on the surface, these impurities will be trapped between the waterproof cloth and the hose after it is wrapped around the hose. This results in poor cleaning ability for hydraulic hoses, requiring frequent replacement of the waterproof cloth. This not only increases material costs but also leads to production interruptions and affects the production schedule.

[0003] A search revealed a Chinese patent document (authorization announcement number CN214930860U), which discloses a disassembly device for a water-removing cloth machine. The disassembly device is used to disassemble and package a rubber hose wound with water-removing cloth. The device includes a frame, a main shaft rotatably connected to the frame, and a water-removing cloth assembly and a packaging assembly connected to the main shaft. The water-removing cloth assembly and the packaging assembly are arranged back-to-back on the frame, and the packaging assembly is equipped with a packaging strap. The water-removing cloth assembly rotates relative to the main shaft and winds the water-removing cloth around it. The packaging assembly rotates relative to the main shaft and wraps the packaging strap around the tube body, which is a rubber hose for removing the water-removing cloth. The water-removing cloth assembly rotates relative to the main shaft to disassemble the water-removing cloth wound around the rubber hose. The packaging component is positioned opposite the dewatering cloth component to wrap the packaging tape around the outer wall of the tube body. This allows the hose to be wrapped with the pre-made packaging tape in a timely manner after the dewatering cloth is removed, improving the packaging efficiency of the hose body. The packaging efficiency is high, and the device can meet basic usage requirements. However, the hydraulic hose cleaning ability is weak, requiring frequent replacement of the dewatering cloth. This not only increases material costs but also leads to production interruptions and affects the production schedule. Utility Model Content

[0004] The purpose of this invention is to provide a water-based cloth unwinding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-based cloth unwinding device, comprising a fixed base, wherein a conversion box is provided on the top of the fixed base;

[0006] The conversion box has a fixed frame welded to its side. Inside the fixed frame, four hollow columns for adjustment are symmetrically welded. The surfaces of the four hollow columns are symmetrically provided with U-shaped grooves for guidance. A spring is connected inside the hollow column. One end of the spring is connected to the inner wall of the fixed frame, and the other end of the spring is connected to a movable frame. The end of the movable frame is slidably disposed inside the hollow column. Two guide columns are symmetrically connected to the outer periphery of the movable frame. The guide columns are slidably disposed inside the U-shaped grooves. An arc-shaped cleaning plate for cleaning hydraulic hoses is installed at the end of the movable frame away from the spring.

[0007] Preferably, the top of the fixed base is equipped with a winding seat and a guide seat, the side of the winding seat is equipped with a power unit for providing power, and the output of the power unit is connected to a transmission mechanism.

[0008] Preferably, the movable part of the transmission mechanism is connected to a hollow rotating shaft via a conversion box, and a rotating disk is connected to the end of the hollow rotating shaft.

[0009] Preferably, an angle adjustment frame is welded to the side of the rotating disk, and a second drive motor is mounted on the side of the angle adjustment frame. The output shaft of the second drive motor is connected to a water cloth storage tray via a coupling.

[0010] Preferably, a height adjustment frame is welded to the top of the guide seat, and two vertical guide rollers for conveying hydraulic hoses are rotatably mounted inside the height adjustment frame.

[0011] Preferably, one of the vertical guide rollers is connected to an adjusting plate, and a first drive motor is mounted on the side of the height adjusting frame.

[0012] Preferably, the first drive motor is connected to the vertical guide roller via a coupling, and four horizontal guide rollers are rotatably mounted on the top of the guide seat.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This water-cloth unwinding device, thanks to the structure of the arc-shaped cleaning plate, utilizes a spring-loaded moving frame during hydraulic hose transport. The moving frame then drives the arc-shaped cleaning plate to press against the surface of the hydraulic hose, cleaning it. The arc-shaped cleaning plate adapts to the contact pressure with the hydraulic hose, thus protecting both the hose and the cleaning plate from damage. Compared to traditional water-cloth unwinding devices, which have weak cleaning capabilities for hydraulic hoses, this structure significantly improves cleaning efficiency. It eliminates the need for frequent water-cloth replacements, reducing material costs, preventing production interruptions, and ensuring production progress.

[0015] This water-based fabric winding and unwinding device benefits from the structure of the water-based fabric storage tray. The power unit drives the hollow rotating shaft to rotate through the transmission mechanism and conversion box. The hollow rotating shaft drives the rotating disk and angle adjustment frame to rotate. Adjusting the angle of the angle adjustment frame activates the second drive motor, which drives the water-based fabric storage tray to rotate. The water-based fabric storage tray makes a circular motion around the hydraulic hose, and the water-based fabric storage tray winds the surface of the hydraulic hose. This structure can improve the winding capacity and increase work efficiency. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5 The water-based cloth unwinding device shown includes a fixed base 1, and a conversion box 2 is provided on the top of the fixed base 1;

[0027] A fixed frame 3 is welded to the side of the conversion box 2. Four hollow columns 301 for adjustment are symmetrically welded inside the fixed frame 3. U-shaped grooves 305 for guidance are symmetrically arranged on the surfaces of the four hollow columns 301. A spring 302 is connected inside the hollow column 301, and damping is provided between the spring 302 and the hollow column 301. One end of the spring 302 is connected to the inner wall of the fixed frame 3, and the other end of the spring 302 is connected to a movable frame 303. The end of the movable frame 303 is slidably disposed inside the hollow column 301. Two guide columns 304 are symmetrically connected to the outer periphery of the movable frame 303, and the guide columns 304 are slidably disposed inside the U-shaped grooves 305. An arc-shaped cleaning plate 306 for cleaning hydraulic hoses is installed at the end of the movable frame 303 away from the spring 302. During the hydraulic hose conveying process, the spring 302 compresses the movable frame 303, which in turn drives the arc-shaped cleaning plate 306 to press against the surface of the hydraulic hose, cleaning the surface. The arc-shaped cleaning plate 306 can adapt to the contact pressure with the hydraulic hose, thus protecting the hydraulic hose and the arc-shaped cleaning plate 306 from damage. When the hydraulic hose enters the cleaning area, the pre-compression force of the spring 302 pushes the movable frame 303 to move along the linear guide towards the hydraulic hose, causing the arc-shaped cleaning plate 306 to gradually approach the surface of the hydraulic hose. After the arc-shaped cleaning plate 306 contacts the surface of the hydraulic hose, as the movable frame 303 continues to move forward, the spring 302 is further compressed, generating greater extrusion force, causing the arc-shaped cleaning plate 306 to fit tightly against the surface of the hydraulic hose, cleaning surface impurities.

[0028] During the cleaning process, if there are raised or uneven areas on the surface of the hydraulic hose, the pressure on the arc-shaped cleaning plate 306 will increase. At this time, the elastic buffer installed between the arc-shaped cleaning plate 306 and the moving frame 303 will undergo elastic deformation to absorb part of the pressure, so that the arc-shaped cleaning plate 306 can adaptively adjust the contact pressure with the hydraulic hose, avoiding excessive pressure from scratching or damaging the surface of the hydraulic hose, and also preventing the arc-shaped cleaning plate 306 from being damaged due to excessive force.

[0029] A winding seat 101 and a guide seat 102 are mounted on the top of the fixed base 1. A power unit 201 for providing power is mounted on the side of the winding seat 101. The output of the power unit 201 is connected to a transmission mechanism 202. The transmission mechanism 202 transmits power to a conversion box 2 (such as a gearbox or worm gear mechanism) to realize the conversion of speed or torque. The movable part of the transmission mechanism 202 is connected to a hollow rotating shaft 203 through the conversion box 2. A rotating disk 204 is connected to the end of the hollow rotating shaft 203. An angle adjustment frame 205 is welded to the side of the rotating disk 204. A second drive motor 206 is mounted on the side of the angle adjustment frame 205. A water cloth collection tray 207 is mounted on the output shaft of the second drive motor 206 through a coupling. The power unit 201 drives the hollow rotating shaft 203 to rotate through the transmission mechanism 202 and the conversion box 2. The hollow rotating shaft 203 drives the rotating disk 204 and the angle adjustment frame 204. The frame 205 rotates, the angle of the angle adjustment frame 205 is adjusted, and the second drive motor 206 is turned on. The second drive motor 206 drives the water cloth storage tray 207 to rotate. The water cloth storage tray 207 makes a circular motion around the hydraulic hose, and the water cloth storage tray 207 winds the surface of the hydraulic hose. The power unit 201 drives the hollow rotating shaft 203 through the transmission mechanism 202 and the conversion box 2, which drives the rotating disk 204 and the angle adjustment frame 205 to rotate to the target angle (such as forming an angle α with the axis of the hydraulic hose). The second drive motor 206 is turned on, and the water cloth storage tray 207 rotates to release the water cloth. At the same time, it makes a circular motion around the hydraulic hose with the angle adjustment frame 205 to achieve spiral winding. The speed of the power unit 201 (controlling the linear speed of the circular motion) and the speed of the second drive motor 206 (controlling the release speed of the water cloth) are adjusted synchronously by the control system to ensure that the tension of the water cloth is uniform and the winding pitch is consistent.

[0030] A height adjustment frame 103 is welded to the top of the guide seat 102. Two vertical guide rollers 105 for conveying hydraulic hoses are rotatably mounted inside the height adjustment frame 103. One of the vertical guide rollers 105 is connected to an adjusting plate 104. A first drive motor 107 is mounted on the side of the height adjustment frame 103 and is connected to the vertical guide roller 105 via a coupling. Four horizontal guide rollers 106 are rotatably mounted on the top of the guide seat 102. The hydraulic hose is passed sequentially through two of the vertical guide rollers. Between 105, between the four horizontal guide rollers 106, inside the conversion box 2, and then through between the four horizontal guide rollers 106 and between the two vertical guide rollers 105, the first drive motor 107 is turned on. The first drive motor 107 drives the vertical guide rollers 105 to rotate, and the vertical guide rollers 105 drive the hydraulic hose to move. The horizontal guide rollers 106 guide the hydraulic hose. The adjusting plate 104 adjusts the distance between the two vertical guide rollers 105, thereby adjusting the pressure of the vertical guide rollers 105 on the hydraulic hose.

[0031] Working principle

[0032] In use, the hydraulic hose is first passed sequentially between two vertical guide rollers 105, between four horizontal guide rollers 106, and inside the conversion box 2. Then it passes between the four horizontal guide rollers 106 and between the two vertical guide rollers 105. The first drive motor 107 is activated, causing the vertical guide rollers 105 to rotate. The vertical guide rollers 105 move the hydraulic hose, while the horizontal guide rollers 106 guide the hydraulic hose. The adjusting plate 104 adjusts the distance between the two vertical guide rollers 105, thereby adjusting the pressure of the vertical guide rollers 105 on the hydraulic hose. The power unit 201 drives the hollow rotating shaft 2 through the transmission mechanism 202 and the conversion box 2. 03. Rotation: The hollow rotating shaft 203 drives the rotating disk 204 and the angle adjustment frame 205 to rotate. Adjusting the angle of the angle adjustment frame 205 activates the second drive motor 206. The second drive motor 206 drives the water cloth storage tray 207 to rotate. The water cloth storage tray 207 makes a circular motion around the hydraulic hose, wrapping the surface of the hydraulic hose. During the hydraulic hose conveying process, the spring 302 squeezes the moving frame 303. The moving frame 303 drives the arc-shaped cleaning plate 306 to squeeze the surface of the hydraulic hose, cleaning the surface of the hydraulic hose. The arc-shaped cleaning plate 306 can adapt to the contact pressure with the hydraulic hose, thereby protecting the hydraulic hose and the arc-shaped cleaning plate 306 from damage.
