Description

Technical Field

[0001] The invention relates to the technical field of surface treatment devices, and in particular to a surface treatment device for producing cable protection tubes. Background Art

[0002] Cable protection tubes are mainly used in power, communication and other projects. Their surface treatment process directly affects the corrosion resistance and service life of the tubes. At present, the industry generally uses mechanical grinding, sandblasting or chemical treatment to remove burrs and rust on the surface of the protection tubes. However, since most protection tubes are long tubular structures, how to achieve efficient positioning and ensure the cleanliness of the surface after treatment in the actual processing process has always been a technical difficulty in production.

[0003] Chinese patent announcement number CN112008512A discloses a surface treatment machine and method for glass fiber reinforced plastic cable protection pipe fittings, including a workbench, a transport device, a rotating device, a grinding device and a collecting device. The workbench is placed on the ground, a transmission device is placed on the left side of the upper end surface of the workbench, a rotating device is arranged on the upper end surface of the workbench and on the right side of the transmission device, a grinding device is arranged inside the rotating device, and a collecting device is arranged on the right side of the upper end surface of the workbench.

[0004] However, the grinding methods and equipment used in the prior art still have the following problems:

[0005] First, it relies on manual positioning operations. During production, workers need to manually adjust the position of the protective tube to align it with the processing equipment. This is not only inefficient, but also prone to uneven grinding due to positioning deviation, and even causes the tube to be partially too thin or damaged, affecting the quality of the finished product;

[0006] Second, there is a lack of real-time cleaning function during the processing. For example, during grinding or sandblasting, the debris and dust generated are likely to remain on the surface or in the gaps of the pipe, and additional cleaning steps are required later. This not only prolongs the process flow, but may also increase the scrap rate due to secondary pollution, especially for protective pipes with high anti-corrosion requirements, as residual impurities will directly reduce their performance.

DETAILED DESCRIPTION

[0035] 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.

[0036] Embodiment 1, as Figure 1 and Figure 2 As shown, a surface treatment device for cable protection tube production includes a base 1, a shielding cover 2 is fixedly connected to the upper end of the base 1, a control console 3 is fixedly connected to the right end of the base 1, a grinding and cleaning structure 5 is arranged in the middle of the upper end of the base 1, a supporting structure 6 is arranged on the left and right sides of the upper end of the base 1 and the inner surface of the adjacent shielding cover 2, a rotating drive structure 4 is fixedly connected to the rear end of the upper end of the base 1, a vacuum cleaner 7 is fixedly connected to the rear end of the vacuum cleaner 7, and a connecting pipe 71 connected to the grinding and cleaning structure 5 is fixedly connected to the input end of the vacuum cleaner 7.

[0037] It should be noted that the shielding cover 2 is a conventional control device, which has been widely used in the prior art. In the present invention, it is only used to realize the function of driving the electrical equipment to start and stop, and its internal structure, operating principle, wiring, and control method are not described in detail.

[0038] At the same time, the above-mentioned vacuum cleaner 7 is a vacuum product with a built-in fan and filter, which can extract dust in the rotating drive structure 4 through the connecting pipe 71 and make it enter the vacuum cleaner 7 for temporary storage. It is a conventional product in the prior art, and its specific internal structure and operating principle will no longer be displayed and elaborated in the present invention.

[0039] During the operation of this embodiment, the cable protection tube is first clamped and limited by the supporting structures 6 on both sides, and further fitted with the lower part of the cable protection tube through the action of the grinding and cleaning structure 5, and the upper side of the cable protection tube is simultaneously pressed and limited by the rotating drive structure 4. The cooperation of the rotating drive structure 4, the grinding and cleaning structure 5, and the supporting structure 6 can adapt to the processing work of different pipe diameters within a certain range, thereby improving the scope of application; during the processing process, the rotating drive structure 4 drives the cable protection tube to rotate under the limitation of the supporting structure 6, and the surface of the pipe is polished by the grinding and cleaning structure 5, and the polished dust is sucked into the vacuum cleaner 7, thereby reducing the accumulation of dirt and dust inside the base 1 and reducing the cost of subsequent maintenance.

[0040] Embodiment 2. Based on embodiment 1, this embodiment cooperates with the center tube 643, the plug 644, the center rod 645 and the connecting rod three 646 rotating on their outer surfaces. The pressure of the end face of the tube on the base plate 641 drives the angle of the connecting rod three 646 to change, thereby pushing the contact blocks 642 away from each other, so that the contact blocks 642 are tightly attached to the inner surface of the tube, and the pipeline is limited by the form of an inner lining. The end face of the tube is simultaneously limited by the action of the compression spring 61, the limiting plate 62 and the base plate 641, thereby reducing the center deviation of the tube caused by force during the grinding process, and improving the accuracy and quality of surface treatment.

[0041] Specifically, to achieve support for the cable protection tube, refer to Figure 3 The supporting structure 6 includes a compression spring 61 fixedly connected to the inner surface of the adjacent shielding cover 2, and the compression spring 61 is fixedly connected to a limiting plate 62 on one side away from the inner wall of the shielding cover 2. The upper end of the base 1 is symmetrically provided with limiting grooves 66 slidably connected to the lower end of the limiting plate 62. Four limiting rods 63 are slidably connected in an annular manner on the inner surface of the limiting plate 62. The four limiting rods 63 and the end of the limiting plate 62 away from the compression spring 61 are fixedly connected to an inner support assembly 64.

[0042] Further, in order to prevent the protective tube from deflecting and shaking during the grinding process, the inner support assembly 64 is used to limit its position, see Figure 4The inner support assembly 64 includes a base plate 641 fixedly connected to four limit rods 63, one end of the base plate 641 away from the limit rod 63 is slidably connected to four contact blocks 642 in an annular distribution, and the inner arc surfaces of the four contact blocks 642 are linearly distributed and rotatably connected to three connecting rods 646, and one end of the base plate 641 away from the limit rod 63 is fixedly connected to a center tube 643, and the inner surface of the center tube 643 is slidably connected to a center rod 645 fixedly connected to the limit plate 62, One end of the rod 645 away from the limit plate 62 is fixedly connected to a plug 644, and one end of the eight connecting rods 3 646 located on the side close to the base plate 641 close to the center tube 643 is rotatably connected to the outer surface of the center tube 643, and one end of the four connecting rods 3 646 located on the side away from the base plate 641 close to the plug 644 is rotatably connected to the outer surface of the plug 644, and one end of the base plate 641 close to the limit plate 62 is fixedly connected to a buffer spring 647 mounted on the outer surface of the center rod 645.

[0043] One end of the pipe is placed on the base plate 641, and the base plate 641 and the buffer spring 647 push the limit plate 62 to move in the direction of the compression spring 61, so that the pipe can be sleeved on the outside of the contact block 642 on the other side. At this time, the pipe is released, and the base plates 641 on both sides will compress the buffer spring 647 and move closer to the compression spring 61 under the pressure of the pipe. However, the center rod 645 is fixed together with the compression spring 61. When the center tube 643 moves with the base plate 641, the center rod 645 is stationary relative to the compression spring 61. At this time, the center rod 645 pushes the plug 644 away from the center tube 643. The connecting rod 3 646 will gradually push the contact block 642 to move away from the center tube 643 during the process, so that the contact block 642 is in close contact with the inner wall of the pipe.

[0044] The outer arc surface of the contact block 642 is rotatably connected with a ball bearing, which can support the pipe without affecting the normal rotation of the pipe.

[0045] Embodiment 3: Based on the embodiment 2, this embodiment further utilizes the function of the electric telescopic rod 5651 to drive the connecting plate 5652 and the T-shaped block 5614 to rise, and synchronously drives the lever 562 to swing through the cooperation of the second connecting rod 5613 and the driving rod 5612, thereby driving the installation shaft 563 and the tensioning wheel 564 to lift the sanding belt 542. Through the function of the tensioning wheel 564 and the pipe, the sanding belt 542 is closely attached to the lower surface of the pipe, and then when the motor 4 55 drives the winding wheel 541 to run, the lower surface of the pipe is processed;

[0046] Furthermore, the surface of the pipe is cleaned by the connecting groove 5653 and the cleaning brush 5654 provided on the upper part of the cleaning plate 565, and the cleaned debris and dust are sucked into the cleaning plate 565 by utilizing the connecting pipe 71, and finally enter the vacuum cleaner 7 through the connecting pipe 71, thereby reducing the dust residue inside the base 1 and further reducing the difficulty and cost of maintenance.

[0047] Specifically, in order to achieve the grinding of burrs and particles on the outer wall of the cable protection tube, refer to Figure 5 and Figure 6 The grinding and cleaning structure 5 includes a slide groove 53 opened at the upper end of the base 1, and the inner surface of the slide groove 53 is rotatably connected with a threaded rod 52, one end of the base 1 is fixedly installed with a motor three 51 that is transmission-connected to the threaded rod 52, the outer surface of the slide groove 53 is threadedly connected with a tray 54 that is slidably connected to the inner surface of the threaded rod 52 and the upper end of the base 1, the inner surface of the tray 54 is provided with a tensioning cleaning component 56 that is connected to the connecting pipe 71, the inner surface of the tray 54 is rectangularly distributed and rotatably connected with four winding wheels 541, the inner surfaces of the two winding wheels 541 on the same side are commonly wound with a sanding belt 542, one end of the tray 54 is fixedly installed with a motor four 55, and the output end of the motor four 55 is transmission-connected to the two opposite winding wheels 541 through an output shaft.

[0048] The motor 3 51 drives the threaded rod 52 to rotate, and the threaded cooperation between the threaded rod 52 and the tray 54 drives the tray 54 to slide left and right on the upper end of the base 1 under the limit of the slide groove 53, thereby cyclically treating the surface of the pipe.

[0049] Further, to drive the abrasive belt 542 to contact the surface of the pipe, refer to Figure 6 The tensioning and cleaning assembly 56 includes a T-shaped driving table 561 fixedly connected to the bottom wall of the inner surface of the tray 54, and the bottom wall of the inner surface of the tray 54 is rotatably connected to four levers 562 distributed along the central rectangular shape of the T-shaped driving table 561. The upper ends of the two levers 562 on the same side are rotatably connected to the mounting shaft 563. The parts of the two mounting shafts 563 located on the inner surfaces of the adjacent sanding belts 542 are rotatably connected to the tensioning wheels 564. A cleaning plate 565 connected to the connecting pipe 71 is arranged on the upper part of the T-shaped driving table 561.

[0050] The winding wheel 541 on the inner wall of the tray 54 is used to wind the sanding belt 542. The sanding belt 542 is in a semi-relaxed state. At this time, the shielding cover 2 will not drive the motor four 55 to run. When the tensioning and cleaning component 56 is actuated to lift the sanding belt 542 and make it fit with the surface of the pipe, the motor four 55 will run to drive the winding wheel 541 to rotate, and then the sanding belt 542 is driven to move rapidly through the action of the winding wheel 541 to process the outer surface of the pipe. The lever 562 drives the installation shaft 563 and the tensioning wheel 564 to move in an arc-shaped trajectory. Corresponding to pipes of different diameters, the fitting angles are different, but the sanding belt 542 can fit on the outer surface of the pipe, so it is suitable for pipes of different diameters and improves the scope of application.

[0051] Further, to achieve the drive of the lever 562 to swing, refer to Figure 7 The left and right ends of the T-shaped driving platform 561 are symmetrically provided with horizontal grooves 5611, and the inner surfaces of the four horizontal grooves 5611 are slidably connected to driving rods 5612 that are slidably connected to the inner surfaces of adjacent levers 562. The side of the driving rod 5612 away from the lever 562 is rotatably connected to a connecting rod 2 5613, and the ends of the two connecting rods 2 5613 on the same side that are close to each other are rotatably connected to a T-shaped block 5614 that is slidably connected to the inner surface of the vertical part of the T-shaped driving platform 561.

[0052] The electric telescopic rod 5651 extends to drive the connecting plate 5652 to move upward, and then drives the T-shaped block 5614 to move upward. During this process, the T-shaped block 5614 will pull the driving rod 5612 to slide in the horizontal groove 5611 through the connecting rod 2 5613, thereby pulling the lever 562 toward the T-shaped driving platform 561, thereby making the installation shaft 563 and the tensioning wheel 564 approach the pipe direction, and finally making the tensioning wheel 564 fit the surface of the pipe.

[0053] The connection between the driving rod 5612 and the lever 562 is a notch, which can provide a margin for the running track of the lever 562 to avoid getting stuck.

[0054] Furthermore, in order to deal with the debris and dust on the surface of the pipe during the grinding process, refer to Figure 7 An electric telescopic rod 5651 is fixedly connected to the middle part of the upper end of the tray 54, and a connecting plate 5652 that is slidably connected to the inner surface of the vertical part of the T-shaped driving platform 561 is fixedly connected to the output end of the electric telescopic rod 5651. The connecting plate 5652 is fixedly connected to two adjacent T-shaped blocks 5614. The upper end of the connecting plate 5652 passes through the inner surface of the vertical part of the T-shaped driving platform 561 and extends to the upper end of the T-shaped driving platform 561 and is fixedly connected to the lower end of the cleaning plate 565. The upper end of the cleaning plate 565 is provided with a plurality of connecting grooves 5653 that are connected to its inner cavity, and the upper end of the cleaning plate 565 is fixedly connected to a plurality of cleaning brushes 5654.

[0055] When the electric telescopic rod 5651 drives the connecting plate 5652 to rise, it will simultaneously drive the cleaning plate 565 to approach the surface of the pipe. When the sanding belt 542 is in contact with the surface of the pipe, the cleaning brush 5654 on the cleaning plate 565 will also be in contact with the pipe. At this time, the distance between the connecting groove 5653 and the surface of the pipe is very small. When the pipe rotates under the action of the rotating drive structure 4 and is polished by the sanding belt 542, the flying debris will be cleaned up by the cleaning brush 5654. At this time, the connecting pipe 71 draws air in the gap through the connecting groove 5653, thereby sucking the debris and granular dust into the cleaning plate 565, and finally sending it to the vacuum cleaner 7 through the connecting pipe 71 for temporary storage, thereby reducing dust accumulation.

[0056] Embodiment 4. Based on embodiment 3, this embodiment drives the slide 413 to slide in the bidirectional screw 412 through the cooperation of the motor 2 43, the transmission shaft 42 and the bidirectional screw 412, thereby driving the driving component 415 to move downward through the cooperation of the connecting rod 1 416, the driving component 415 and the limit seat 414 until the L-shaped connecting rod 4154 and the arc-shaped support platform 4155 contact the surface of the pipe, and utilizes the action of the motor 1 4156 and the L-shaped connecting rod 4154 to drive the pipe to rotate in the direction opposite to the movement direction of the sanding belt 542, and then cooperates with the action of the sanding belt 542 to process the surface of the pipe, and can synchronously adapt to the use of pipes of different sizes, thereby improving the scope of application.

[0057] Specifically, in order to drive the pipe to rotate and cooperate with the supporting structure 6 to press and limit it, refer to Figure 8 The rotary drive structure 4 includes a rotary drive assembly 41 which is symmetrically distributed on the left and right and fixedly connected to the rear portion of the upper end of the base 1. The ends of the rotary drive assemblies 41 on both sides that are close to each other are rotatably connected to a transmission shaft 42. A second motor 43 drives the transmission shaft 42 to rotate, and drives the components in the rotary drive assembly 41 to operate through the transmission shaft 42. One end of the rotary drive assembly 41 that is away from the transmission shaft 42 is fixedly connected to a second motor 43 that is transmission-connected to the transmission shaft 42.

[0058] Further, in order to drive the driving member 415 to move downward until it contacts the surface of the pipe, refer to Fig. 9 The rotating drive assembly 41 includes an L-shaped support rod 411 fixedly connected to the upper end of the base 1, the inner surface of the horizontal part of the L-shaped support rod 411 is rotatably connected to a bidirectional screw 412 connected to the transmission shaft 42 through a bevel gear transmission, the outer surface of the bidirectional screw 412 is symmetrically threadedly connected to a slide 413 slidably connected to the inner surface of the horizontal part of the L-shaped support rod 411, the lower ends of the two slides 413 are rotatably connected to a connecting rod 416, the lower end of the horizontal part of the L-shaped support rod 411 is fixedly connected to a limiting seat 414, and the inner surface of the limiting seat 414 and the connecting rods 416 on both sides are jointly provided with a driving component 415.

[0059] The transmission shaft 42 drives the bidirectional screw 412 to rotate through the bevel gear. During the rotation of the bidirectional screw 412, it can drive the slide 413 threadedly connected to it to slide in the L-shaped support rod 411, thereby driving the slide 413 to move closer to or away from each other, and then utilizing the action of the connecting rod 416 to drive the driving component 415 to move up and down in the limit seat 414.

[0060] Further, in order to achieve the compression of the pipe and drive the pipe to rotate, refer to Fig.10 The driving component 415 includes a cross slider 4151 which is slidably connected to the inner surface of the limit seat 414, the lower end of the cross slider 4151 is fixedly connected to a sliding rod 4152 which is rotatably connected to the connecting rods 416 on both sides, the inner surface of the sliding rod 4152 is rotatably connected to a roller 4153, the left and right ends of the cross slider 4151 are fixedly connected to L-shaped connecting rods 4154, the lower ends of the vertical parts of the two L-shaped connecting rods 4154 are fixedly connected to arc-shaped support platforms 4155 through a clamping seat, the inner surfaces of the two arc-shaped support platforms 4155 are connected by rubber belts 4157 wrapped around them through pulleys, the pulleys in the arc-shaped support platforms 4155 on both sides are connected by transmission rollers, and a motor 4156 which is transmission-connected to the transmission roller is fixedly installed at one end of one of the arc-shaped support platforms 4155 away from the transmission roller.

[0061] When the connecting rod 416 pushes the sliding rod 4152 to move downward, the L-shaped connecting rods 4154 on both sides will be pulled downward through the cross slider 4151. When the roller 4153 contacts the surface of the pipe, the rubber belt 4157 wrapped in the arc support platform 4155 under the L-shaped connecting rod 4154 will also contact the surface of the pipe. At this time, the rubber belt 4157 will fit on the surface of the pipe within a certain angle range. The rubber belt 4157 has high friction and can drive the pipe to rotate while following the drive of the motor 4156, thereby cooperating with the action of the sanding belt 542 to grind the pipe. Synchronously, under the action of the roller 4153, it can ensure that the lower part of the pipe is always between the mounting shaft 563 and the tensioning wheel 564, and fits on the upper part of the cleaning plate 565, thereby ensuring the stability of the processing process.
