Description

Technical Field

[0001] This application relates to the field of pipeline cleaning technology, and in particular to a cleaning device for the inner wall of a wire-spinning pipe. Background Technology

[0002] The wire coil is a core component in a high-speed wire rod rolling production line. It is mainly used to wind red-hot wire into regular coils. Its structure is usually a spiral or arc-shaped tubular channel.

[0003] During the wire rolling process, iron oxide scale is generated when the high-temperature wire passes through the inside of the spinning tube. At the same time, fine metal particles on the surface of the wire fall off due to friction and gradually adhere to the inner wall of the spinning tube to form a layer. This layer will damage the smoothness of the inner wall of the spinning tube, causing the wire to deviate from its running trajectory and resulting in defects such as excessive ellipticity and loose coiling. Therefore, it is necessary to clean the inner wall of the spinning tube regularly.

[0004] Currently, industrial pipeline cleaning equipment is mainly divided into two categories: dry (mechanical brushing, high-pressure gas purging) and wet (high-pressure water cleaning). Among them, existing dry pipeline cleaning equipment mostly adopts a straight rod brush structure. This type of equipment has poor bending adaptability. Since the spinneret is usually a spiral or arc-shaped tubular channel with a small radius of curvature, the straight rod brush has difficulty passing through its curved structure and cannot effectively clean the inner wall, leading to difficulties in the cleaning work.

[0005] To address this issue, we propose a cleaning device for the inner wall of a wire-spinning tube, which solves the problem that existing dry pipe cleaning equipment has difficulty cleaning the inner wall of spiral or arc-shaped wire-spinning tubes. Utility Model Content

[0006] In order to solve the problems mentioned in the background art, this application provides a cleaning device for the inner wall of a wire feeding tube.

[0007] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0008] In order to solve the problems mentioned in the background art, this application provides a cleaning device for the inner wall of a wire feeding tube.

[0009] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0010] A cleaning device for the inner wall of a spinning tube includes a first end cap and a second end cap, which are respectively press-fitted to both ends of the spinning tube. A drive shaft is rotatably connected to the center of the first end cap. One end of the drive shaft is connected to the output end of a motor. The other end of the drive shaft is provided with a plurality of optical shafts, and universal joints are connected between the optical shafts. Four sets of base plates are elastically connected to the outer side of each optical shaft. Brushes are installed on the side of each base plate. One of the outermost optical shafts is coaxially connected to the other end of the drive shaft. The end face of another outermost optical shaft is coaxially connected to a connecting rod. Four sets of connecting blocks are elastically connected to the outer side of the connecting rod. Rollers are coaxially connected to the inside of each connecting block via pins. A pipe is passed through the second end cap, and the free end of the pipe is connected to the input end of a vacuum pump.

[0011] By adopting the above technical solution, several optical axes are connected by universal joints, making the cleaning device adaptable to the curved structure of spiral or arc-shaped spinnerets, solving the problem that traditional straight-bar brushes cannot penetrate deeply; the elastically connected base plate allows the brush to fit tightly against the inner wall of the spinneret, cleaning iron oxide scale and metal particles; the air pump adsorbs the cleaned impurities through the pipeline, avoiding secondary pollution.

[0012] Furthermore, four pairs of first through holes are provided on the side of the optical axis, and the two first through holes in a pair of first through holes are arranged vertically. A first slide rod slides in the first through hole, and a first spring is connected between the first slide rod and the first through hole. The free end of the first slide rod is connected to the base plate.

[0013] By adopting the above technical solution, the first spring pushes the first slide rod to make the brush fit tightly against the inner wall of the spinneret tube, adapting to spinnerets of different diameters and ensuring cleaning effect; the vertically arranged first through hole allows the base plate to move elastically in the radial direction, enhancing the device's adaptability to curved pipes.

[0014] Furthermore, the connecting rod has four sets of second through holes on its side, a second slide rod slides in the second through hole, a second spring connects the second slide rod and the second through hole, and the free end of the second slide rod is connected to the connecting block.

[0015] By adopting the above technical solution, the second spring pushes the second slide rod to make the roller fit tightly against the inner wall of the wire-spinning tube, providing support and reducing the resistance of the device's movement, while adapting to the bending of the pipe and ensuring that the cleaning device moves along the pipe axis.

[0016] Furthermore, the four sets of base plates, the four pairs of first through holes, the four sets of connecting blocks, and the four sets of second through holes are all axially and evenly distributed on the outside of the optical axis and the connecting rod.

[0017] By adopting the above technical solution, the uniformly distributed structure makes the device balanced in terms of force inside the pipeline, avoiding vibration and wear caused by eccentric rotation, and improving cleaning stability and device life.

[0018] Furthermore, a threaded rod is installed at the top of the connecting rod, and a threaded hole is opened on the end face of the other outermost optical axis, and the threaded rod and the threaded hole are threadedly engaged.

[0019] By adopting the above technical solution, the threaded connection facilitates the assembly and disassembly of the connecting rod. After the connecting rod slides to the other end of the wire-spinning tube, the user can remove the connecting rod to avoid affecting subsequent cleaning.

[0020] Furthermore, both the first end cap and the second end cap are fitted with sealing plugs on their adjacent sides, and the diameter of the sealing plugs matches the inner diameter of the spinning tube.

[0021] By adopting the above technical solution, the sealing plug and the inner wall of the spinneret are press-fitted to form a sealed space, preventing impurities from leaking out during the cleaning process, while ensuring that the air pump can effectively adsorb impurities.

[0022] Furthermore, an air hood is installed on the top of the second end cap, and the air hood is connected to the pipeline.

[0023] By adopting the above technical solutions, the gas hood expands the extraction range, improves the impurity adsorption efficiency, and ensures that the accumulated layers are removed in a timely manner to avoid accumulation.

[0024] Furthermore, a spline is provided on the outer side of the drive shaft.

[0025] By adopting the above technical solution, the spline enhances the transmission stability between the drive shaft and the motor output end, avoids slippage, and ensures that power is efficiently transmitted to the optical shaft.

[0026] Furthermore, the diameter of the optical axis is smaller than the inner diameter of the spinning tube, and the diameters of the first end cap and the second end cap are larger than the outer diameter of the spinning tube.

[0027] By adopting the above technical solution, the diameter of the optical axis is smaller than the inner diameter of the pipe, ensuring that the device can be smoothly inserted into the spinneret tube; the diameter of the end cap is larger than the outer diameter of the pipe, which facilitates the fixing of the device and provides sealing support.

[0028] In summary, this application has the following technical effects:

[0029] By connecting several optical axes with universal joints, the cleaning device can adapt to the curved structure of spiral or arc-shaped spinnerets, solving the problem that traditional straight-bar brushes cannot penetrate deeply; the flexible base plate allows the brush to fit tightly against the inner wall of the spinneret, cleaning iron oxide scale and metal particles; the air pump adsorbs the cleaned impurities through the pipeline, avoiding secondary pollution.

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] This utility model provides a cleaning device for the inner wall of a wire-spinning tube, referring to... Figure 1 To be continued Figure 5The device includes a first end cap 1 and a second end cap 8, which are respectively press-fitted to both ends of the spinning tube. A drive shaft 6 is rotatably connected to the center of the first end cap 1. One end of the drive shaft 6 is connected to the output end of the motor. The other end of the drive shaft 6 is provided with several optical shafts 2, and universal joints 5 are connected between the optical shafts 2. Four sets of base plates 3 are elastically connected to the outer side of the optical shafts 2. Brushes 4 are installed on the side of the base plates 3. One of the outermost optical shafts 2 is coaxially connected to the other end of the drive shaft 6. The end face of another outermost optical shaft 2 is coaxially connected to a connecting rod 12. Four sets of connecting blocks 16 are elastically connected to the outer side of the connecting rod 12. Inside 16, a roller 17 is coaxially connected via a pin. A pipe 11 is connected through the second end cap 8. The free end of the pipe 11 is connected to the input end of the air pump. The roller 17 at the end of the connecting rod 12 supports the device and guides the direction of travel of the optical shaft 2. When it reaches the other end of the spinning tube, it can be disassembled. Then, the interference fit between the first end cap 1 and the second end cap 8 and the two ends of the spinning tube creates a sealed space inside the spinning tube. The motor drives the drive shaft 6 to rotate, which in turn drives the optical shaft 2 to rotate through the universal joint 5. The base plate 3 and brush 4 on the outside of the optical shaft 2 rub the inner wall to remove the accumulated layer. The air pump sucks in the impurities through the pipe 11 and the air cover 10 to complete the cleaning.

[0038] After the above operations are completed, the first end cap 1 can be removed and the device pulled backward. Then, the motor-driven device can be rotated to clean the areas that were not cleaned in the previous operation. After the inner wall of the spinning tube is completely cleaned, the first end cap 1 can be closed and the impurities can be sucked into the pipe 11 using a vacuum pump. Since the pipe 11 is equipped with a filter screen, it can block the impurities. After all operations are completed, the impurities in the pipe 11 can be removed.

[0039] Reference Figure 4 The optical axis 2 has four pairs of first through holes 18 on its side, and the two first through holes 18 in a pair of first through holes 18 are arranged vertically. A first slide rod 20 slides in the first through hole 18. A first spring 19 is connected between the first slide rod 20 and the first through hole 18. The free end of the first slide rod 20 is connected to the base plate 3. When the optical axis 2 moves in the spinning tube, the elastic force of the first spring 19 causes the base plate 3 to press the inner wall outward. The brush 4 automatically adjusts its position according to the curvature of the tube to maintain the contact pressure with the inner wall and ensure that the accumulated layer is effectively brushed away.

[0040] Reference Figure 3 The connecting rod 12 has four sets of second through holes on its side. A second slide rod 15 slides in the second through hole. A second spring connects the second slide rod 15 and the second through hole. The free end of the second slide rod 15 is connected to the connecting block 16. When the connecting rod 12 moves with the optical axis 2, the elastic force of the second spring keeps the roller 17 in contact with the inner wall. The rolling friction of the roller 17 reduces the resistance of the device and guides the device to move.

[0041] The four sets of base plates 3, the four pairs of first through holes 18, the four sets of connecting blocks 16, and the four sets of second through holes are all axially and evenly distributed on the outside of the optical axis 2 and the connecting rod 12. The four sets of base plates 3 and rollers 17 are evenly distributed, so that the optical axis 2 and the connecting rod 12 are subjected to symmetrical forces when rotating, reducing vibration and ensuring that the brush 4 makes uniform contact with the inner wall, thus improving the uniformity of cleaning.

[0042] Reference Figure 4 The top of the connecting rod 12 is fitted with a threaded rod 13, and the end face of the other outermost optical axis 2 is provided with a threaded hole 14. The threaded rod 13 and the threaded hole 14 are threadedly engaged. The connecting rod 12 can be quickly installed or removed by screwing the threaded rod 13 and the threaded hole 14 together.

[0043] Reference Figure 1 and Figure 2 The first end cap 1 and the second end cap 8 are each equipped with a sealing plug 9 on their respective sides, and the diameter of the sealing plug 9 matches the inner diameter of the spinning tube. The sealing plug 9 is inserted into both ends of the spinning tube and blocks the escape path of impurities through interference fit. When the air pump is working, a negative pressure is formed in the pipeline, and impurities are directionally sucked into the pipeline 11 to avoid contaminating the working environment.

[0044] Reference Figure 5 An air hood 10 is installed on the top of the second end cap 8. The air hood 10 is connected to the pipe 11. The air hood 10 is located on the top of the second end cap 8 and is connected to the pipe 11. When the air pump is working, a strong negative pressure is formed near the air hood 10, which quickly sucks the cleaned impurities into the pipe 11.

[0045] The drive shaft 6 has a spline 7 on its outer side. The tooth structure of the spline 7 meshes with the spline groove at the output end of the motor. There is no relative slippage when transmitting torque, which ensures that the drive shaft 6 rotates stably and drives the optical shaft 2 and the brush 4 to clean efficiently.

[0046] The diameter of the optical axis 2 is smaller than the inner diameter of the spinneret tube, and the diameters of the first end cap 1 and the second end cap 8 are larger than the outer diameter of the spinneret tube. The optical axis 2 can easily pass through the inlet of the spinneret tube. The first end cap 1 and the second end cap 8 are stuck at both ends of the pipe and fixed by the sealing plug 9 and interference fit to form a stable cleaning work platform.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.
