[0002] Pasting FRP lined PTFE sheet is a delicate and complicated process, which requires the operator to have certain technical knowledge and practical experience. Generally, the surface of the sheet is cleaned first, and the excess material between the sheets is trimmed and cleaned with special tools to keep the bonding surface clean and tidy. Then the surface of the PTFE sheet is activated for easy pasting. Then a suitable adhesive is selected and applied to the sheet. Then the FRP lining is attached to the pasting surface of the PTFE sheet, and then the two are pressed to bond them together. In the prior art, when pasting and fixing the FRP lined PTFE sheet, a heavy object is generally pressed on the upper surface of the sheet to perform pressurized curing. However, this pressurizing operation has certain disadvantages. During the pressurizing process, the pressure at all parts of the sheet cannot be uniform, and there may still be certain bubbles between the sheets of the two materials, which affects the quality of the final product.

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0026] like Figure 1As shown, it is a structural schematic diagram of the pasting and fixing device of the utility model. The glass fiber reinforced plastic lined polytetrafluoroethylene board pasting and fixing device of the utility model is provided with an operating platform 10. The operating platform 10 is provided with two positioning plates 20 which are parallel to each other and vertically arranged on the upper surface of the operating platform 10. A slide groove 11 is provided on the operating platform 10 and below the two ends of the positioning plate 20. Slide blocks (not marked in the figure) are provided at the bottom of the two ends of the positioning plate 20. The slide blocks are located in the slide grooves 11. A threaded rod (not marked in the figure because it is hidden) is also provided in the slide groove 11. One end of the threaded rod is connected to the slider, and the other end passes through the slide groove 11 and is located on the side of the operating platform 10. At the same time, a rotating shaft 12 is provided at this end. A fixer 30 is provided on the inner side of the positioning plate 20. The fixer 30 is used to fix the glass fiber reinforced plastic lined polytetrafluoroethylene board. Preferably, the number of the fixers 30 is four, which are evenly distributed on the two positioning plates 20, that is, each positioning plate 20 is respectively provided with two fixers 30. A support frame 40 is provided at the bottom of the operating platform 10. There are four support frames 40. The support frames 40 are respectively located at four corners of the operating platform 10 to support the operating platform 10 to a certain height.

[0027] See also Figure 2 As shown, it is a schematic diagram of the structure of the fixer 30, and also Figure 1 The enlarged structural view of the middle A part shows that the fixture 30 of the utility model is provided with a mounting plate 31, a support rod 32 and a clamping plate 33. The mounting plate 31 is fixed to the positioning plate 20 by bolts. A threaded shaft 34 is provided in the vertical direction in the middle position of the mounting plate 31. The support rod 32 is sleeved and fixed on the lower end of the threaded shaft 34. The clamping plate 33 is movably sleeved on the upper end of the threaded shaft 34. A groove 35 is provided on the mounting plate 31 and at the top end of the threaded shaft 34. The groove 35 is used to rotate the threaded shaft 34 with the help of a torque wrench to adjust the distance between the clamping plate 33 and the support rod 32.

[0028] In other embodiments, the pasting and fixing device of the utility model is also provided with a separate pressing plate (not shown in the figure). The pressing plate is an independent structure, which is a flat plate structure. During use, the pressing plate can be placed directly above the upper surface of the glass fiber reinforced plastic lined PTFE plate, that is, placed below the clamping plate 33. The pressing plate can make the pressure on various places on the glass fiber reinforced plastic lined PTFE plate more uniform, so that the two materials of the plate are more firmly pasted.

[0029] The working principle of the glass fiber reinforced plastic lined PTFE plate pasting and fixing device of the utility model is as follows: during use, the glass fiber reinforced plastic lined PTFE plate coated with adhesive is placed above the operating platform 10, and the distance between the two positioning plates 20 is adjusted to adapt to the width of the PTFE plate to fix it. The specific operation is to rotate the rotating shaft 1212 on the side of the operating platform 10 to rotate the threaded shaft 34, thereby driving the movement of the slider, thereby adjusting the distance between the positioning plates 20, so that the two positioning plates 20 press the PTFE plate in the horizontal direction; in addition, the glass fiber reinforced plastic lined PTFE plate coated with adhesive is directly placed between the support rod 32 and the pressing plate 33 of the fixer 30, and then with the help of an external tool, such as a wrench or a torque wrench, the tool is tightened. It is placed in the groove 35, and then the threaded shaft 34 is rotated, so that the height of the clamping plate 33 sleeved on the threaded shaft 34 can be adjusted. The height of the clamping plate 33 is adjusted to finally make the PTFE plate tightly fixed between the clamping plate 33 and the support rod 32. In a preferred embodiment, an independent pressing plate is also used, and the pressing plate is placed above the PTFE plate. During use, from top to bottom are the clamping plate 33, the pressing plate, the PTFE plate and the support rod 32. As the threaded shaft 34 rotates, the clamping plate 33 is gradually pressed down, and finally the same pressure is applied to the four corners of the PTFE plate, so that the entire PTFE plate is subjected to a more uniform external pressure, thereby making the pasting and fixing process of the PTFE plate lined with FRP more standardized, and further improving the product quality.

[0030] Through the above technical scheme, the adhesive fixing device of the utility model can adjust the fixing width during use, which is suitable for fixing PTFE plates of different sizes. In addition, the fixing device 30 can fix the glass fiber reinforced plastic lined PTFE plate stably and evenly, thereby improving the quality of the processed products.

[0031] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
