Description

Technical Field

[0001] This utility model relates to a tooling structure, and more particularly to a tooling structure for anti-corrosion treatment of steel plates after shot blasting, specifically a device for applying anti-corrosion tape after shot blasting of steel plates. Background Technology

[0002] After shot blasting, the edge 50mm of the steel plate is generally not painted with anti-corrosion coating to prevent the paint from being damaged by high temperature during subsequent welding, which could lead to welding defects.

[0003] Currently, in traditional construction processes, the application of tape to the 50mm edge of the steel plate surface is mainly done manually. However, the limited operating space on the underside of the steel plate makes tape application and cutting very difficult, easily leading to problems such as weak adhesion and uneven cutting of the anti-corrosion tape. Furthermore, the amount of steel plate anti-corrosion work on construction sites is enormous. If the entire process is done manually with tape, it will not only be extremely inefficient, severely hindering project progress, but also increase labor and time costs, making it difficult to meet construction requirements.

[0004] Therefore, improvements are urgently needed to better meet construction requirements. Utility Model Content

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 and 2 As shown, a device for applying anti-corrosion tape after shot blasting of steel plates includes: a support frame 1, a slide rail 4, a support rod 2, a pressure roller 6, a tape pulley 16, and a cutting structure, etc.

[0031] The support frame 1 includes a clamp at the bottom and a support plate at the top. The clamp is a horizontally placed U-shaped groove, with fixing bolts 5 on its upper and lower ends, which can be tightened onto the frame of the steel plate shot blasting conveyor belt. The support plate consists of two straight plates, vertically spaced and parallel, with their lower ends connected to the upper ends of the clamp and their upper ends suspended.

[0032] The slide rail 11 is linear and cantilevered laterally to the support plate. That is, one end of the slide rail is connected to the support plate, and the other end is suspended. Furthermore, there are two slide rails 11, each connected to the same support plate, and they are arranged vertically at intervals and parallel to each other.

[0033] The support rod 2 is a cylindrical straight rod that is horizontally cantilevered and connected to the support plate. That is, one end of the support rod 2 is connected to the support plate, and the other end is suspended. Moreover, the support rod 2 and the slide rail 11 are respectively connected to different support plates. At the same time, there are two support rods 2, which are connected to the same support plate and are arranged vertically at intervals and parallel to each other.

[0034] The pressure roller 6 is a horizontally placed cylinder, which is connected to the slide rail 11 through the bracket assembly 3, and can move along the slide rail and be fastened on the slide rail.

[0035] The support assembly 3 includes a vertical rod, a horizontal rod, a horizontal plate, and a tension spring. There are two vertical rods, both telescopic tubular, comprising an outer tube 301 and an inner tube 303, with the inner tube 303 freely movable along the outer tube 301. The horizontal rod is a strip-shaped straight plate, with both ends connected to the ends of the outer tube and movably connected to the slide rail. The horizontal plate 304 is a rectangular flat plate, with its rear end edge connected to the middle of the inner tube and its front end protruding forward beyond the vertical rod. The compression spring 302 is disposed between the horizontal rod and the horizontal plate, with both ends connected to the horizontal rod and the horizontal plate respectively, allowing the distance between the horizontal plate and the horizontal rod to change with the extension and contraction of the compression spring. The two ends of the rotating shaft of the pressure roller 6 are connected to the ends of the inner tube 303, allowing the pressure roller 6 to move up and down with the undulations of the steel plate surface when rolling the steel plate 19, ensuring close contact between the pressure roller and the steel plate surface.

[0036] Furthermore, the pressure roller 6 and the support assembly 3 are both in two sets, each connected to a different slide rail, so that they are opposite each other and the distance between them is adapted to the thickness of the steel plate, so that the pressure roller can simultaneously abut against both sides of the steel plate.

[0037] Furthermore, both the cross-section of the slide rail 11 and the cross-section of the crossbar are dovetail-shaped and fit together, allowing the crossbar to be fitted into the slide rail and move smoothly. Simultaneously, the slide rail 11 has multiple vertically penetrating positioning holes. These positioning holes are screw holes, allowing fastening screws 13 to be screwed into them and pressed against the crossbar to prevent movement, thereby preventing lateral movement of the pressure roller. Preferably, the positioning holes are evenly distributed along the slide rail, with a spacing of approximately 25 mm.

[0038] The pulley 16 is cylindrical, with an inner diameter slightly larger than the outer diameter of the support rod 2 and an outer diameter slightly smaller than the inner diameter of the core of the anti-corrosion tape roll 15. This allows it to be movably fitted onto the support rod and movably embedded in the core of the anti-corrosion tape roll, enabling the pulley to move axially along the support rod and allowing the anti-corrosion tape roll to rotate flexibly on the pulley, thus achieving tape unwinding. Preferably, the pulley 16 is connected to the support assembly 3 via a first connecting plate 14. The first connecting plate 14 is a long, straight plate, with one end connected to an outer tube 301 and the other end connected to the edge of one end of the pulley 16, ensuring that the pulley and the support assembly move laterally in sync.

[0039] Furthermore, it also includes a stop lever 17. The stop lever 17 is a straight rod with a connecting ring at one end. This connecting ring is an open circular ring with an inner diameter smaller than the outer diameter of the support rod 2, and is on the same plane as the stop lever. The connecting ring is detachably snapped onto the support rod and abuts against the end of the belt pulley, so that the stop lever and the first connecting plate are located on opposite sides of the anti-corrosion tape roll, preventing axial movement of the anti-corrosion tape roll to the sides and ensuring that the tape's unfolding direction does not deviate.

[0040] The cutting structure includes a baffle 9 and a blade 8. The baffle 9 is a rectangular flat plate, the length of its rear end edge being approximately equal to the length of the horizontal plate 304, and is hinged to the front end edge of the horizontal plate, allowing it to rotate around the front end edge. A tension spring 10 is also provided between the baffle 9 and the horizontal plate 304. One end of the tension spring 10 is connected to the upper part of the baffle 9, and the other end is connected to the horizontal plate 304 via a second connecting plate 18. The second connecting plate 18 is a short plate, vertically mounted on the horizontal plate for easy connection to the tension spring. Thus, the tension spring can exert a pulling force on the baffle, causing the baffle to move towards the pressure roller.

[0041] The blade 8 is a strip saw blade, which is located at the outer edge of the baffle 9 and can compress and cut the anti-corrosion tape.

[0042] The support wheel 7 is roller-shaped and can rotate around its axis. This axis is mounted on one side of the outer edge of the baffle 9, placing the support wheel 7 outside the side of the baffle 9. Under the action of the tension spring 10, it can roll against the steel plate 19. The diameter of the support wheel 7 is larger than the thickness of the baffle 9, allowing it to lift the outer end of the baffle 9, thus detaching the blade 8 from the anti-corrosion tape. After the anti-corrosion tape is fully applied, the support wheel detaches from the steel plate, causing the baffle to move towards the horizontal plate under the action of the tension spring, thereby causing the blade to press against the anti-corrosion tape and cut it.

[0043] The cutting structure consists of two sets, which are opposite to each other, and can simultaneously complete the cutting operation when applying anti-corrosion tape to both surfaces of the steel plate.

[0044] The method of using this utility model is as follows:

[0045] like Figure 3 As shown, the chuck is attached to the frame of the shot blasting production line, allowing the steel plate on the line to pass between two sets of pressure rollers. Then, according to the anti-corrosion application size, the positions of the support assembly and the belt pulley are adjusted, and the anti-corrosion tape roll is fitted onto the belt pulley, along with the stop bar. Subsequently, the end of the anti-corrosion tape is applied to the end of the steel plate, and the pressure rollers press against the tape, ensuring a tight fit. As the steel plate moves along the production line, the tape automatically applies to it. During this process, the support rollers roll against the surface of the steel plate, raising the stop plate and disengaging the blade from the tape, ensuring continuous application.

[0046] like Figure 4 As shown, after the entire steel plate is applied and detached from the pressure roller, the support roller also detaches from the steel plate, causing the baffle to move closer to the pressure roller. This causes the blade to press the tape and cut it, automatically completing the tape application process.

[0047] When both sides of the steel plate need to be treated with anti-corrosion, this utility model can be installed on both sides of the shot blasting production line simultaneously, such as... Figure 5 As shown, this allows the application of anti-corrosion tape on both sides to be completed simultaneously, effectively improving construction efficiency.

[0048] This invention can be directly installed on a steel plate shot blasting production line and achieve automated operation, effectively solving the problems encountered in manual construction and greatly improving construction efficiency and quality.

[0049] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
