Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, in particular to a cleaning device for a steel wire mesh skeleton used in the production of composite pipes. Background Art

[0002] The steel wire mesh skeleton plastic composite pipe is made of high-strength plasticized steel wire mesh skeleton and thermoplastic polyethylene as raw materials, with steel wire winding mesh as the skeleton reinforcement of polyethylene plastic pipe, high-density polyethylene (HDPE) as the matrix, and high-performance HDPE modified adhesive resin is used to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, so that it has excellent composite effect. The high-strength steel wire reinforcement is coated in continuous thermoplastic plastic, so this composite pipe overcomes the shortcomings of steel pipe and plastic pipe respectively, while maintaining the advantages of steel pipe and plastic pipe respectively.

[0003] When the wire mesh skeleton is being made, the winding machine winds multiple steel wires into a barrel-shaped mesh, but there may be some dust or impurity particles on the surface of the steel wire, and the steel wire will also rub against other metal or non-metallic guide structures during the weaving process. Over time, it is easy to produce fine debris, dust or impurity particles, and debris generated by rubbing, all of which protrude from the surface of the wire mesh skeleton. Therefore, when using adhesive resin to connect the inner and outer layers of high-density polyethylene with the steel mesh skeleton, the wall thickness of the composite pipe is limited. If the particle impurities are large, the composite pipe may not be tightly attached to the high-density polyethylene after production, thereby affecting the quality of the composite pipe; at the same time, the adhesion of impurities to the steel wire is poor. If there are too many impurities on the steel wire, it will affect the quality of the composite pipe and cause the high-density polyethylene to be not tightly attached to the steel wire. However, it is more troublesome to clean the entire wire mesh skeleton after production, and if a separate cleaning device is required to clean it, the processing efficiency will be reduced.

[0004] Therefore, the present invention provides a wire mesh skeleton cleaning device that can be used on a composite pipe production line. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Example

[0022] like Figure 1-Figure 9 As shown, a wire mesh skeleton cleaning device for composite pipe production described in the present invention includes support columns 1 arranged on both sides of a winding machine, and also includes a transmission mechanism 4 located at the top of the support column 1, which includes a worm 42 and a connecting shaft 421 fixedly connected to both ends of the worm 42, which is assembled to drive a transmission wheel 43 fixedly connected to the connecting shaft 421 to rotate through the movement of the wire mesh skeleton, so that the worm 42 rotates, thereby rotating a worm wheel 45 meshing with the worm 42, which is used to provide power support for the cleaning mechanism 5; the transmission wheel 43, which A special-shaped tooth 431 is fixedly provided on the outside, and is assembled so that the end of the special-shaped tooth 431 cooperates with the mesh of the wire mesh skeleton, so that the transmission wheel 43 is driven to rotate when the wire mesh skeleton moves; the cleaning mechanism 5 located on one side of the transmission mechanism 4 is assembled to drive the movable ring 56 to rotate through the bevel gear 46 fixed to the bottom of the worm gear 45, so that the brush 58 on the inner wall of the movable ring 56 cleans the wire mesh skeleton; the collecting box 55 is arranged to be located at the bottom of the movable ring 56, and is used to collect the cleaned foreign particles.

[0023] In this embodiment, after the winding machine makes the wire mesh into a wire mesh skeleton, the finished wire mesh skeleton moves forward, and the brush 58 on the inner wall of the movable collar 56 cleans the wire mesh skeleton. At the same time, the mesh drives the special-shaped teeth 431 on the transmission wheel 43 to rotate, so that the transmission wheel 43 drives the worm 42 to rotate, and the worm wheel 45 meshing with the worm 42 rotates accordingly, thereby driving the bevel gear ring 57 meshing with the bevel gear 46 at the bottom of the worm wheel 45 to rotate. When the movable collar 56 rotates, the brush 58 on its inner wall is moved again. The surface of the movable wire mesh skeleton is rotated for cleaning, and the adhered particle impurities are swept away and separated from the wire mesh skeleton for subsequent further cleaning. The cleaned particle impurities fall below the movable collar 56 and fall into the collection box 55 through the through groove 59 located below. The particle impurities are collected to a certain extent to avoid the removed particle impurities being retained in the movable collar 56 and affecting subsequent use. The dust particle impurities are cleaned by utilizing the manufacturing process of the wire mesh skeleton, without the need to use a separate motor, thereby reducing costs.

[0024] like Figure 1-Figure 4 As shown, a connecting pipe 3 is installed at one end of the winding machine, and a support seat 2 is fixedly installed on the top of the support column 1, and the support seat 2 cooperates with the winding machine; the transmission mechanism 4 also includes a support frame 41 fixedly connected to the top of the support column 1, and the connecting shaft 421 is rotatably connected to the side walls on both sides of the upper end of the support frame 41. A fixed shaft 44 is fixedly connected to the top of the support frame 41, and the fixed shaft 44 is rotatably connected to the worm gear 45; the transmission wheels 43 are symmetrically arranged and are respectively located on both sides of the worm 42, and the special-shaped teeth 431 are all matched with the wire mesh skeleton; a movable ring 56 is fixedly provided with a bevel gear ring 57 on one side close to the transmission mechanism 4, and the bevel gear ring 57 is meshed with the bevel gear 46. A through groove 59 is opened on the side wall of the movable ring 56, and annular baffles 510 are respectively arranged on both sides of the brush 58.

[0025] In this embodiment, the winding machine weaves multiple steel wires into shape, and the connecting tube 3 provides internal support for the wire mesh skeleton to prevent the wire mesh skeleton from deformation. The woven wire mesh skeleton continues to move forward and rub on the connecting tube 3. The connecting tube 3 can also play a certain cleaning role on the inner wall of the wire mesh skeleton. The granular impurities are separated from the wire mesh skeleton during friction. The special-shaped teeth 431 on the transmission wheel 43 are in contact with the wire mesh skeleton. The tip of the special-shaped teeth 431 can be set to extend into the mesh holes of the wire mesh skeleton of different sizes. In cooperation with them, when the wire mesh skeleton moves, the mesh holes on the wire mesh skeleton drive the special-shaped teeth 431 on the transmission wheel 43 to rotate together with the transmission wheel 43. When the wire mesh skeleton moves, the transmission wheels 43 on both sides of the worm 42 always cooperate with the wire mesh skeleton. When the transmission wheel 43 rotates, it drives the connecting shaft 421 to rotate on the support frame 41. When the worm 42 rotates, it drives the worm wheel 45 meshing with the worm 42 to rotate. The bevel gear ring 57 set on one side of the movable ring 56 is meshed with the bevel gear 46 fixedly connected to the bottom of the worm wheel 45. Therefore, when the wire mesh skeleton moves, the worm wheel 45 can be rotated through the transmission wheel 43 to provide power for the cleaning mechanism 5. The moving speed of the wire mesh skeleton is slow after weaving, so the rotation speed of the transmission wheel 43 is also relatively slow. Similarly, the rotation speed of the movable ring 56 is also slow, which will not cause dust particles to fly quickly.

[0026] like Figure 4-Figure 9 As shown, the cleaning mechanism 5 also includes a connecting seat 51 installed on the top of the support column 1, and the connecting seat 51 includes a fixed base 511 fixedly connected to the top of the support column 1, and a connecting ring 512 is fixedly connected to the top of the fixed base 511. A connecting groove 52 is provided on the top of the fixed base 511, and a placement bin 53 is also provided in the fixed base 511. The placement bin 53 is communicated with the connecting groove 52, and the placement bin 53 is slidably connected to the collection box 55; a bevel gear ring 57 is fixedly provided on the side of the movable ring 56 close to the transmission mechanism 4, and the bevel gear ring 57 is meshed with the bevel gear 46. A through groove 59 is provided on the side wall of the movable ring 56, and annular baffles 510 are respectively provided on both sides of the brush 58; the annular baffle 510 is fixedly connected to the inner wall of the movable ring 56, and the side of the annular baffle 510 away from the movable ring 56 is inclined to the brush 58.

[0027] In the present embodiment, the bevel gear ring 57 provided on one side of the movable collar 56 meshes with the bevel gear 46 fixedly connected to the bottom of the worm gear 45. Therefore, when the wire mesh skeleton moves, the bevel gear 46 can be rotated through the transmission wheel 43, and the movable collar 56 rotates accordingly. The movable collar 56 is rotatably connected with the connecting seat 51, and the connecting seat 51 supports the movable collar 56. When the movable collar 56 rotates, the movable collar 56 rotates inside the connecting seat 51. The multiple groups of brushes 58 provided on the inner wall of the movable collar 56 clean the surface of the wire mesh skeleton when following the rotation of the movable collar 56. While the brushes 58 rotate and sweep the wire mesh skeleton, the wire mesh skeleton itself is also moving, which can strengthen the cleaning force of the brushes 58 on the wire mesh skeleton and sweep away the dust particles adhered to its surface. After the dust particles are separated from the wire mesh skeleton, they fall to the bottom of the movable collar 56. At this time, the brushes 58 located at the movable collar 56 can be used to clean the wire mesh skeleton. The through groove 59 at the bottom falls into the collecting box 55, and some dust particles that have not fallen under the movable ring 56 may enter the through groove 59 under the rotation of the movable ring 56. As the movable ring 56 continues to rotate, the through groove 59 rotates to the bottom and communicates with the connecting groove 52 opened on the fixed base 511. The dust particles inside it therefore fall into the collecting box 55, and the dust particles generated by cleaning are collected to avoid accumulation in the movable ring 56. The inclined annular baffles 510 arranged on both sides of the brush 58 can, to a certain extent, block the flying of dust particles when the brush 58 is sweeping, and make the cleaned dust particles be collected in the collecting box 55 as much as possible. The collecting box 55 is slidably connected to the fixed base 511 and is placed in the placing bin 53 during operation. When cleaning is needed, the collecting box 55 can be pulled out to remove the dust particles collected inside it.

[0028] like Figure 4-Figure 6 As shown, the movable ring 56 is located inside the connecting ring 512, and the movable ring 56 is rotatably connected to the connecting seat 51; the brush 58 and the through groove 59 are arranged as a group, and are staggered, one end of the brush 58 is fixedly connected to the inner wall of the movable ring 56, and the other end is in contact with the wire mesh skeleton; a guide plate 54 is provided at the connection between the fixed base 511 and the connecting ring 512, and the lower end of the guide plate 54 is fixedly connected to the side wall of the connecting groove 52.

[0029] In the present embodiment, there are multiple brushes 58 on the inner wall of the movable collar 56, and anti-static materials can be used to avoid static electricity generated by long-term friction contact with the wire mesh frame and affecting the cleaning effect. A through groove 59 is provided between each two adjacent brushes 58. When the movable collar 56 rotates, the brush 58 cleans and sweeps the surface of the wire mesh frame to sweep away the adhered dust particles. After the particle impurities are separated from the wire mesh frame, they fall to the lower position of the movable collar 56 and fall into the collection box 55 through the through groove 59 located at the lower position of the movable collar 56 and connected to the connecting groove 52. The guide plate 54 can guide the particle impurities into the collection box 55. When the movable collar 56 rotates, there may be some particles due to The obstruction of the brush 58 causes the granular impurities that fail to fall below the movable ring 56 in time to enter the through groove 59. As the movable ring 56 continues to rotate, the through groove 59 moves to the top of the wire mesh frame, and the dust granular impurities inside it fall out from it, some of which fall below the movable ring 56, and some may fall on the wire mesh frame. The through groove 59 originally located in the middle and lower part of the movable ring 56, when the movable ring 56 drives it to rotate toward the connecting groove 52, when the through groove 59 is connected with the connecting groove 52, the impurity particles inside it fall into the collecting box 55. After being cleaned by the cleaning mechanism 5, the dust granular impurities adhered to the surface of the wire mesh frame are separated from it, which provides convenience for subsequent further cleaning.

[0030] Working principle: When in use, the winding machine weaves the steel wire into a steel mesh skeleton, and the connecting tube 3 is used to provide internal support for the steel mesh skeleton. The woven steel mesh skeleton continues to move forward. During the movement, the friction between the steel mesh skeleton and the connecting tube 3 can clean the inside of the steel mesh skeleton to a certain extent, so that the impurities adhering to the inside are separated from the steel mesh skeleton. At the same time, the mesh holes on the steel mesh skeleton drive the special-shaped teeth 431 on the transmission wheel 43 to rotate, thereby causing the worm 42 fixedly connected to the transmission wheel 43 to rotate, and the worm 42 is meshed with the worm wheel 45, thereby driving the worm wheel 45 and the bevel gear 46 to rotate; The bevel gear 46 is meshed with the helical gear ring 57 on the movable collar 56. Therefore, when the wire mesh skeleton moves, the movable collar 56 is rotated. The multiple groups of brushes 58 arranged on the inner wall of the movable collar 56 brush the surface of the wire mesh skeleton to remove the dust particles adhering to the surface. The dust particles fall to the bottom of the movable collar 56 and fall into the collection box 55 through the through groove 59. Some dust particles that fail to fall into the collection box 55 may fall into the through groove 59 under the rotation of the movable collar 56. When the movable collar 56 continues to rotate, the dust particles in the through groove 59 move with the through groove 59. When it rotates to above the guide plate 54, the dust particles in the through groove 59 fall into the collection box 55, and the granular impurities generated during cleaning are collected to avoid accumulation in the movable collar 56 to affect the subsequent cleaning effect. At the same time, the collection box 55 can be pulled out to process the impurities in the collection box 55.
