Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, and in particular to a high-strength tape coating machine. Background Technology

[0002] High-strength tape is a type of tape with excellent physical and adhesive properties, typically used in applications requiring high strength and durability for fixing, protection, or bonding. High-strength tape coating machines are key pieces of equipment specifically designed for producing high-strength tape, featuring efficient coating, precise control, automated unwinding and rewinding, and wide applicability. However, existing tape coating machines often leave small dust and impurity particles adhering to the uncoated tape, which cannot be effectively removed by a scraper.

[0003] Existing technology, patent number CN222000569U, discloses a tape coating machine. By installing a shaking component, the uncoated tape is shaken within a certain amplitude. Smaller dust particles on the tape are stirred up by inertia during the shaking, and then removed by a dust removal component, ensuring the cleanliness of the tape and product quality. However, in actual use, this existing technology uses fixed hot air ducts to dry the tape. The fixed position and direction of the hot air duct outlet can easily lead to uneven heating of the coating surface. Areas near the air outlet may experience excessively high temperatures or wind speeds, causing the coating surface to harden too quickly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a high-strength tape coating machine.

[0005] This utility model is achieved through the following technical solution:

[0006] A high-strength adhesive tape coating machine includes a base, with an unwinding roller and a take-up roller mounted on the top of the base. A support frame is provided between the unwinding roller and the take-up roller, and the support frame is fixedly connected to the top of the base. A drying component and a spraying mechanism are installed inside the support frame, with the drying component installed on one side of the spraying mechanism. The drying component includes a blower, which is fixedly connected to the top of the support frame. The output end of the blower is connected to an air distribution pipe, which is fixedly connected to the top of the support frame. The bottom end of the air distribution pipe is connected to two air delivery hoses, which penetrate the support frame and extend to the inside of the support frame. The bottom end of the air delivery hoses is connected to a heating box, which heats the inside of the support frame. The heating box is described as follows: multiple electric heating tubes are fixedly connected inside; a partition is fixedly connected inside; a wind collector is fixedly connected to the bottom of the heating box; connecting rods are fixedly connected to both sides of the heating box; a fixed frame is rotatably connected to the outer side of one of the connecting rods 12, and the fixed frame is fixedly connected to the inner side of the support frame; a housing is rotatably connected to the outer side of the other connecting rod, and the housing is fixedly connected to the inner side of the support frame; a gear is fixedly connected to the outer side of the other connecting rod; an electric push rod is fixedly connected to one side of the support frame; a rack is fixedly connected to the output end of the electric push rod; the rack is slidably connected to the inside of the housing; and the top of the rack meshes with two gears.

[0007] As can be seen, the above technical solution enables hot air to act more evenly on the coating, thereby facilitating uniform heating of the adhesive surface.

[0008] Optionally, in one possible implementation, the spraying mechanism includes a gear pump fixedly connected to the top of a support frame. Both the output and input ends of the gear pump are connected to a connecting pipe. One end of one connecting pipe is connected to an adhesive storage tank, which is fixedly connected to the top of the support frame. The bottom end of the other connecting pipe is connected to a spray pipe. A protective cover is fixedly connected to the outside of the spray pipe and to the inside of the support frame. The connecting pipe passes through the protective cover and communicates with the spray pipe. Multiple first and second spray heads are connected to the outside of the spray pipe. The second spray heads are mounted on one side of the first spray heads. An applicator roller is rotatably connected inside the protective cover.

[0009] It can be seen that the above technical solution can further smooth the glue after spraying, which is beneficial to improving the quality of glue spraying.

[0010] The beneficial effects of this utility model are:

[0011] This invention, by setting up a drying component, differs from existing technologies. Through the meshing connection between a rack and two gears, the rack, in its reciprocating motion, drives two heating chambers to alternately swing and dry the adhesive on the high-strength tape. This creates an alternating hot air coverage area, which uniformly sweeps and dries the surface of the high-strength tape, resulting in even heating and reducing localized over-drying or under-drying.

[0012] Meanwhile, by setting up a spraying mechanism, compared with the existing technology, after multiple first nozzles spray the surface of the high-strength tape, the coating roller rolls and coats the surface of the high-strength tape again. The adhesive is squeezed and coated evenly on the surface of the high-strength tape by pressure, making the adhesive distribution more uniform. Attached Figure Description

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0024] Example 1: The embodiments disclosed in this application are as follows Figure 1-7 The high-strength tape coating machine shown includes a base 1, with an unwinding roller 2 and a take-up roller 3 mounted on the top of the base 1. A support frame 4 is provided between the unwinding roller 2 and the take-up roller 3. The support frame 4 is fixedly connected to the top of the base 1. A drying component and a spraying mechanism are installed inside the support frame 4. The drying component is installed on one side of the spraying mechanism.

[0025] The drying assembly includes a blower 5, which is fixedly connected to the top of a support frame 4. An air distribution duct 6 is connected to the output end of the blower 5, and the air distribution duct 6 is also fixedly connected to the top of the support frame 4. Two flexible air supply hoses 7 are connected to the bottom of the air distribution duct 6, passing through the support frame 4 and extending to its inner side. A heating box 8 is connected to the bottom of the flexible air supply hose 7, and the heating boxes 8 are symmetrically distributed inside the support frame 4. Multiple electric heating tubes 9 are fixedly connected inside the heating box 8, as are partitions 10. An air collecting hopper 11 is fixedly connected to the bottom of the heating box 8. Connecting rods 12 are fixedly connected to both sides of the heating box 8. A fixing frame 14 is rotatably connected to the outer side of one of the connecting rods 12, and the fixing frame 14 is fixedly connected to the inner side of the support frame 4. A housing 15 is rotatably connected to the outer side of the other connecting rod 12, and the housing 15 is fixedly connected to the inner side of the support frame 4. Another connecting rod 12 is fixedly connected to a gear 16 on its outer side, and an electric push rod 17 is fixedly connected to one side of the support frame 4. A rack 18 is fixedly connected to the output end of the electric push rod 17. The rack 18 is slidably connected to the inside of the outer shell 15. The top of the rack 18 is meshed with two gears 16. The electric push rod 17 pushes the rack 18 to reciprocate, so that the rack 18 can mesh and drive the two gears 16 to reciprocate. This allows the gears 16 to drive the two heating boxes 8 to reciprocate through the connecting rod 12. The two heating boxes 8 are symmetrically distributed inside the support frame 4, so that the two heating boxes 8 can alternately drive hot air to dry the glue on the surface of the high-strength tape. The air collecting hopper 11 can concentrate the hot air so that the hot air can better dry the glue, making the surface of the high-strength tape evenly heated and reducing the phenomenon of local over-drying or under-drying.

[0026] Example 2: The spraying mechanism includes a gear pump 19, which is fixedly connected to the top of the support frame 4. Both the output and input ends of the gear pump 19 are connected to a connecting pipe 20. One end of one connecting pipe 20 is connected to an adhesive storage tank 21, which is fixedly connected to the top of the support frame 4. The bottom end of the other connecting pipe 20 is connected to a spray pipe 22. A protective cover 23 is fixedly connected to the outside of the spray pipe 22, and the protective cover 23 is fixedly connected to the inside of the support frame 4. The connecting pipe 20 passes through the protective cover 23 and connects to the spray pipe 22. Multiple connecting pipes are connected to the outside of the spray pipe 22. A first nozzle 24 and a second nozzle 25 are provided. The second nozzle 25 is installed on one side of the first nozzle 24. An applicator roller 26 is rotatably connected inside the protective cover 23. Under the action of the gear pump 19, the glue inside the glue storage tank 21 can be extracted and delivered to the spray pipe 22 so that multiple first nozzles 24 can spray. At the same time, multiple second nozzles 25 can spray the glue onto the applicator roller 26, so that the glue is evenly squeezed and applied on the surface of the high-strength tape by pressure, thereby making the glue more evenly distributed on the surface of the high-strength tape.

[0027] Working principle of this utility model: This utility model designs a high-strength adhesive tape coating machine, the specific structure of which is shown in the attached instruction manual. Figure 1-7 As shown, in this technical solution, through the cooperation of various structures, when it is necessary to spray adhesive onto the high-strength tape, firstly, one end of the high-strength tape on the unwinding roller 2 passes through the support frame 4 and is wound onto the take-up roller 3. Then, the gear pump 19 is started, which can extract the adhesive from the adhesive storage tank 21 and transport the adhesive to the spray nozzle 22 through the connecting pipe 20 on the output end. This allows multiple first nozzles 24 to spray adhesive onto the surface of the high-strength tape, while multiple second nozzles 25 can spray adhesive onto their surfaces. As the high-strength tape moves during take-up, the applicator roller 26 can apply adhesive again onto the surface of the high-strength tape, thus applying adhesive to the surface of the high-strength tape. When it is necessary to dry the adhesive, the blower 5 is started. The blower 5 can... Wind energy is generated and delivered to two heating chambers 8 via air distribution pipe 6. Multiple electric heating tubes 9 inside the heating chambers 8 generate heat, allowing hot air to be blown onto the surface of the high-strength tape through the air collection hopper 11 to dry the adhesive. Simultaneously, the electric push rod 17 is activated, which drives the rack 18 to move. The top of the rack 18 meshes with two gears 16, so that when the rack 18 moves back and forth, it drives the gears 16 to rotate back and forth. The gears 16, through the connecting rod 12, drive the heating chambers 8 to swing back and forth, so that the two heating chambers 8 can swing alternately, driving the hot air to dry the adhesive on the high-strength tape. Finally, the dried high-strength tape is wound up by the winding roller 3.

[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
