Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion, in particular to a scraper for producing glass fiber reinforced plastic lining. Background Art

[0002] FRP lining, also known as fiberglass reinforced plastic lining, uses glass fiber and its products (such as glass cloth, glass tape, and glass mat) as reinforcements, with a synthetic resin matrix. It exhibits excellent corrosion resistance, wear resistance, temperature resistance, and mechanical strength. FRP lining is generally manufactured by applying pre-mixed resin and glass cloth layer by layer to the substrate surface, which cures to form a solid anti-corrosion layer.

[0003] FRP lining is generally made of multiple layers of glass cloth pasted on the surface of the substrate. Each layer of glass cloth requires a different resin content, so different forces are needed to scrape the glass cloth flat. When the operator uses a scraper to scrape the glass cloth flat, the scraping force is difficult to maintain constant. Too much or too little scraping force will cause the resin content of the glass cloth to deviate, which is not conducive to bonding with other glass cloths. This requires relying on the operator's experience to make it, otherwise quality problems will occur. Summary of the Invention

[0004] The utility model solves the problem that it is difficult for an operator to maintain a constant scraping force when scraping glass cloth, and provides a scraper for making glass fiber reinforced plastic linings, which can conveniently adjust and maintain the scraping force on the glass cloth, thereby improving the production quality of the glass fiber reinforced plastic linings.

[0005] In order to solve the above problems, the technical solution of the present utility model is:

[0006] The left and right sides of the box body are symmetrically provided with a limit plate, and the left limit plate is sleeved on the outside of the rotating rod in the left part of the box body through a waist-shaped hole, and the limit plate is connected to the left plate of the box body through an elastic rope. A driving rod is provided between the two limit plates, and the lower end of the driving rod is rotatably connected to the bottom plate of the box body and the upper end movably penetrates the top plate of the box body. The opposite surfaces of the two limit plates are connected to the driving rod through a pull rope, and a worm gear is outerly arranged on the driving rod on the upper side of the box body, and the worm gear is driven to rotate by the worm.

[0007] Furthermore, the rotating rods extending out of the box body are all covered with torsion springs, and one end of each torsion spring is connected to the box body and the other end is connected to the peripheral wall of the rotating rod.

[0008] Furthermore, the scraper is a rectangular plate with the thickness of the lower end gradually decreasing from top to bottom. When the torsion spring on the left support is in a natural state, the upper ends of the two connecting plates tilt to the right, and the lower end of the scraper is higher than the lower end of the roller on the support.

[0009] Furthermore, when the elastic rope connected to the left-side limiting plate is in a natural state, there is a distance between the left and right ends of the waist-shaped hole on the limiting plate and the rotating rod.

[0010] Furthermore, a first friction pattern is provided on the inner side surface of the waist-shaped hole, and a second friction pattern is provided on the peripheral wall of the rotating rod.

[0011] Furthermore, vertical plates are fixed to the front and rear parts of the outer top of the box body, the rear end of the worm is rotatably connected to the rear vertical plate, and the front end moves through the front vertical plate, and the worm engages with the worm wheel; the outer top surface of the box body is connected to a handle.

[0012] Through the above technical solution, the beneficial effects of the utility model are:

[0013] The utility model enables the rollers on the two supporting members to move in opposite directions when the box body drives the scraper to move downward, so that the downward movement distance of the scraper can be controlled, and thus the top pressure of the scraper on the glass cloth can be controlled. After the downward movement distance of the scraper is adjusted, the rotation of the rotating rods on the two supporting members is limited by the limiter, so that the pressure of the scraper on the glass cloth can be kept constant. When the rollers of the utility model roll on the glass cloth, the glass cloth can be scraped flat and the resin content in the glass cloth can be controlled. The utility model is easy to use and has little reliance on personnel experience. BRIEF DESCRIPTION OF THE DRAWINGS

The support member on the left side comprises a rotating rod 4 and a connecting plate 5, the rotating rod 4 is a round rod, the rotating rod 4 is located in the left part of the box body 1, the front and rear ends of the rotating rod 4 respectively pass through and are rotatably connected to the front and rear side plates of the box body 1 through a bearing 10, both ends of the rotating rod 4 are connected to a connecting plate 5, the connecting plate 5 is a rectangular plate, and the two connecting plates 5. A roller 3 is rotatably connected between the lower parts of the opposite surfaces. The limiting member includes a limiting plate 6 and a driving rod 7. The left and right parts of the box body 1 are symmetrically slidably provided with a limiting plate 6. The left limiting plate 6 is sleeved on the outside of the rotating rod 4 in the left part of the box body 1 through a waist-shaped hole 8. The left end of the limiting plate 6 is connected to the left plate of the box body 1 through an elastic rope 9. A driving rod 7 is provided between the two limiting plates 6. The lower end of the driving rod 7 is rotatably connected to the bottom plate of the box body 1 through a second bearing 11, and the upper end is movable through the top plate of the box body 1. The opposite surfaces of the two limiting plates 6 are connected to the driving rod 7 through a pull rope 12. The driving rod 7 on the upper side of the box body 1 is covered with a worm gear 13, and the worm gear 13 is driven to rotate by the worm 14.

[0022] The rotating rods 4 extending out of the box body 1 are all covered with torsion springs 15 . One end of each torsion spring 15 is connected to the box body 1 , and the other end is connected to the peripheral wall of the rotating rod 4 .

[0023] The scraper 2 is a rectangular plate with a thickness at the lower end gradually decreasing from top to bottom. When the torsion spring 15 on the left support is in a natural state, the upper ends of the two connecting plates 5 are tilted to the right, and the lower end of the scraper 2 is higher than the lower end of the roller 3 on the support.

[0024] The limiting plate 6 is a rectangular plate that slides sideways in contact with the inner wall of the box body 1 . When the elastic rope 9 connected to the limiting plate 6 on the left side is in a natural state, there is a gap between the left and right ends of the waist-shaped hole 8 on the limiting plate 6 and the rotating rod 4 .

[0025] A friction pattern 16 is provided on the inner side surface of the waist-shaped hole 8 , and a friction pattern 2 17 is provided on the peripheral wall of the rotating rod 4 .

[0026] The front and rear parts of the outer top of the box body 1 are fixed with vertical plates 18, the rear end of the worm 14 is rotatably connected to the rear vertical plate 18, and the front end is movable through the front vertical plate 18 and is connected to a rotating plate 19, and the worm 14 engages with the worm wheel 13; the outer top surface of the box body 1 is connected to a handle 20.

[0027] In the initial state, there is a gap between the ends of the waist-shaped hole 8 on the left limit plate 6 and the left rotating rod 4, and there is a gap between the ends of the waist-shaped hole 8 on the right limit plate 6 and the right rotating rod 4, and the lower end of the scraper 2 is higher than the lower ends of the rollers 3 on the left and right support members;

[0028] When in use, the utility model is placed on the glass cloth that needs to be scraped flat, and the handle is gripped to make the box body 1 drive the scraper 2 to move downward. During the downward movement of the box body 1, the rotating rod 4 on the left support rotates clockwise, and the rotating rod 4 on the right support rotates counterclockwise, the torsion spring 15 is twisted, and the rollers 3 on the left and right support members move in opposite directions until the lower end of the scraper 2 moves downward to press the glass cloth and the pressure on the glass cloth is appropriate. Then, the box body 1 stops moving downward. At this time, the worm 14 is rotated, the worm 14 engages the worm gear 13 to rotate, and the worm gear 13 drives the driving rod 7 to rotate. When the driving rod 7 rotates The left and right side limiting plates 6 are pulled relative to each other by the pull rope 12 until the friction line 16 at the left end of the waist-shaped hole 8 on the left limiting plate 6 presses against the friction line 2 17 on the left rotating rod 4, and the friction line 16 at the right end of the waist-shaped hole 8 on the right limiting plate 6 presses against the friction line 2 17 on the right rotating rod 4. Moreover, since the meshing of the worm wheel and the worm 14 is a self-locking structure, the worm wheel 13 can only be driven to rotate by the worm 14, and the driving rod 7 will not rotate due to the rotation of the rotating rod 4. Therefore, the rotating rods 4 on the two supporting members are limited and will not rotate, which can ensure that the pressure of the scraper 2 on the glass cloth is constant;

[0029] According to the different resin contents required by different glass cloths, the downward movement distance of the scraper 2 is adjusted, so that different glass cloths are subjected to different constant pressures. When the roller 3 of the utility model rolls on the glass cloth, it can scrape the glass cloth flat and control the resin content in the glass cloth.

However, the present invention is not limited to the above embodiments. Without violating the spirit of the present invention, that is, within the scope of disclosure, any equivalent or equivalent deformation or replacement of the technical solution of the utility model shall fall within the scope of protection of the present invention.
