DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, instead of all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] Reference Figures 1-4The application relates to a roller rubber lining device capable of adjusting the inner diameter of a pipeline, which comprises a fixed block 1, a rubber storage groove 2, a guide assembly 3, a rubber scraping roller 4 and an adjusting assembly. The fixed block 1 is the supporting base of the whole device and provides a stable mounting platform. The fixed block 1 can be made of high-strength metal material. The rubber storage groove 2 is arranged on the top of the fixed block 1 and can store resin to provide an impregnation environment for glass fiber bundles. The groove wall of the rubber storage groove 2 can be made of corrosion-resistant material to prevent the resin glue from corroding the groove body. The bottom of the rubber storage groove 2 is provided with a glue discharge port for conveniently cleaning and replacing the glue liquid when needed. The guide assembly 3 is arranged in the rubber storage groove 2 and can guide the movement of the glass fiber bundles in the rubber storage groove 2, thereby ensuring that the glass fiber bundles can be uniformly impregnated with resin. The rubber scraping roller 4 is rotatably arranged in the rubber storage groove 2 and rolls in contact with the glass fiber bundles, thereby scraping off the excess resin on the surface of the glass fiber bundles and adjusting the resin content. The rubber scraping roller 4 can be made of rubber or silicone material and has a certain elasticity, which can effectively scrape off the excess glue liquid without damaging the glass fiber bundles. The diameter and length of the rubber scraping roller 4 can be selected according to the width of the glass fiber bundles and production requirements, so that the width of the glass fiber bundles can be fully covered and uniform scraping of the glue can be realized. The adjusting assembly 5 is arranged on the top of the fixed block 1 and is provided with the rubber scraping roller 4 at the bottom. The height of the rubber scraping roller 4 can be adjusted according to the different inner diameters of the pipelines, so that the adjustment of the resin content can be realized to adapt to different rubber lining requirements.

[0036] In some embodiments, the adjusting assembly 5 comprises two support plates 51, two sliding grooves 56, a sliding plate 52, a fixed plate 53, a driving motor 54 and a lead screw 55. The two support plates 51 are symmetrically arranged on the fixed block 1. The support plates 51 can be made of metal materials such as aluminum alloy and can be welded and fixed on the fixed block 1. The support plates 51 have sufficient strength and rigidity and can bear various acting forces generated during the operation of the adjusting assembly 5. The sliding grooves 56 are vertically arranged at the ends of the two support plates 51 close to each other. The sliding plate 52 is slidably arranged between the two sliding grooves 56. The rubber scraping roller 4 is arranged at the bottom of the sliding plate 52. The sliding of the sliding plate 52 can drive the rubber scraping roller 4 to move up and down, thereby realizing the adjustment of the height of the rubber scraping roller 4. The fixed plate 53 is arranged on the top of the two support plates 51 and can be connected with the support plates 51 through bolts or welding, so that the connection is firm. The driving motor 54 is fixedly arranged on the fixed plate 53 and can be fixed through a bolt assembly. The driving motor 54 can provide power for adjusting the position of the rubber scraping roller 4. The driving motor 54 can be a servo motor or a stepping motor. The output shaft of the driving motor 54 penetrates through the fixed plate 53 and is connected with the lead screw 55. The lead screw 55 is screw-connected with the sliding plate 52.

[0037] When the driving motor 54 rotates, the lead screw 55 is driven to rotate. Due to the screwing relationship between the lead screw 55 and the sliding plate 52, the sliding plate 52 will rotate with the lead screw 55. Since the sliding plate 52 is constrained at both ends, the rotation of the sliding plate 52 will be converted into up and down movement along the sliding groove 56, thereby adjusting the height of the glue scraping roller 4. By controlling the rotation angle and speed of the driving motor 54, the position of the sliding plate 52 and the glue scraping roller 4 can be accurately adjusted.

[0038] In some embodiments, the sliding plate 52 includes a plate body 521, two sliding blocks 522 are symmetrically arranged at both ends of the plate body 521, and a threaded hole is arranged at the top of the plate body 521 and screwed with the lead screw 55. The depth of the threaded hole can be set according to actual production needs, and the sliding block 522 and the plate body 521 are fixed by welding or bolt connection. The shape and size of the sliding block 522 are matched with the sliding groove 56, and the sliding block 522 can be tightly embedded in the sliding groove 56 and freely slide therein. Through the cooperation of the sliding block 522 and the sliding groove 56, the sliding plate 52 can stably move up and down between the support plates 51, thereby driving the glue scraping roller 4 to adjust the position.

[0039] In some embodiments, the sliding plate 52 further includes a rotating groove 523 and a fixed shaft 524. The rotating groove 523 is arranged at the bottom of the plate body 521, the fixed shaft 524 is arranged in the rotating groove 523, the glue scraping roller 4 is coaxially installed on the fixed shaft 524 and can freely rotate around the fixed shaft 524. Therefore, the glue scraping roller 4 can flexibly rotate when contacting the glass fiber bundle, thereby achieving uniform glue scraping.

[0040] In some embodiments, the sliding groove 56 is a dovetail groove, which has good guiding and stability and can effectively prevent the sliding block 522 cooperating therewith from shaking or deviating during sliding.

[0041] In some embodiments, the guide assembly 3 includes an inlet roller 31, an outlet roller 32 and a glue coating roller 33. The inlet roller 31 is arranged at the top of one side of the glue storage groove 2 and can guide the glass fiber bundle into the glue storage groove 2. The outlet roller 32 is arranged at the top of the other side of the glue storage groove 2 and can guide the glass fiber bundle out of the glue storage groove 2. The glue coating roller 33 is arranged at the bottom of the glue storage groove 2 and between the inlet roller 31 and the outlet roller 32. The glass fiber bundle passes through the top of the inlet roller 31, the bottom of the glue coating roller 33 and the top of the outlet roller 32 in sequence, so as to realize sufficient contact between the glass fiber bundle and the resin glue solution in the glue storage groove 2 and uniform coating of the resin on the surface of the glass fiber bundle. The surfaces of the inlet roller 31, the outlet roller 32 and the glue coating roller 33 can be smoothly arranged, which can reduce the friction between the glass fiber bundle and the roller surface and prevent the glass fiber bundle from being damaged.

[0042] In some embodiments, the glue scraping roller 4 is arranged between the outgoing roller 32 and the glue applying roller 33, and can be in contact with the glass fiber bundle leaving the glue solution, so as to scrape the excess glue solution on the surface of the glass fiber bundle, thereby controlling the glue content of the glass fiber bundle and ensuring that the excess glue solution has been scraped before the glass fiber bundle leaves the glue storage tank.

[0043] In some embodiments, the guide assembly 3 further comprises a plurality of guide wheels 34, which are arranged at intervals and rotatably arranged on the incoming roller 31, the outgoing roller 32 and the glue applying roller 33. The glass fiber bundle can be in contact with the guide wheels 34, and the guide wheels 34 can further guide the movement track of the glass fiber bundle, so as to ensure the smooth running of the glass fiber bundle on the guide wheels 34 and avoid the problems such as deviation and winding of the glass fiber bundle.

[0044] In some embodiments, a control system is further included, which is electrically connected with the driving motor 54. By inputting the inner diameter of the pipe to be lined with glue, the angle at which the driving motor 54 needs to rotate can be calculated, so as to adjust the glue scraping roller 4 to the appropriate position, thereby realizing the automatic control of the glue lining device.

[0045] The specific working process and principle are as follows:

[0046] A proper amount of resin glue solution is injected into the glue storage tank 2, and the temperature, viscosity and other parameters of the glue solution are adjusted according to the characteristics of the glue solution and the production requirements. According to the inner diameter of the pipe to be lined with glue, the angle at which the driving motor 54 needs to rotate is calculated, so as to adjust the glue scraping roller 4 to the appropriate position. The driving motor 54 is started, and the driving motor 54 drives the screw rod 55 to rotate, so that the sliding plate 52 moves up and down along the sliding groove 56, and the glue scraping roller 4 is adjusted to the appropriate position. After the adjustment is completed, the driving motor 54 is locked to prevent the position of the glue scraping roller 4 from changing. For small-diameter pipes, the glue scraping roller 4 moves upward to reduce the scraping force, so that the glass fiber bundle retains more glue, so as to meet the demand of small-diameter pipes for high bonding force; for large-diameter pipes, the glue scraping roller 4 moves downward to increase the scraping force, so as to reduce the glue content of the glass fiber bundle and ensure the quality of the inner lining layer.

[0047] The glass fiber bundle is introduced from the top of the incoming roller 31, and the glass fiber bundle enters the glue storage tank 2 under the guidance of the incoming roller 31. In the glue storage tank 2, the glass fiber bundle passes through the bottom of the glue applying roller 33 in sequence, and fully contacts and impregnates the glue solution. In this process, the guide wheels 34 stabilize the movement track of the glass fiber bundle, so as to ensure the smooth running of the glass fiber bundle.

[0048] The glass fiber bundle after impregnation passes through the glue scraping roller 4, the glue scraping roller 4 rolls in contact with the glass fiber bundle, and the excess glue solution on the surface of the glass fiber bundle is scraped, so as to accurately control the glue content of the glass fiber bundle.

[0049] The glass fiber bundle after the glue scraping is led out from the top of the outlet roller 32, and then is wound on the inner wall of the pipe to be rubber lined, and is wound according to a predetermined winding process, so that the production of the glass steel inner lining of the pipe is completed.

[0050] The above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
