Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive cloth-based tape coating mechanisms, in particular to a hot melt adhesive cloth-based tape coating mechanism. Background Art

[0002] Hot melt adhesive cloth-based tape coating machine is a kind of equipment that does not require solvents, does not contain water, and is 100% solid and fusible polymer. It is solid at room temperature and is heated and melted to a certain degree to become a liquid adhesive that can flow and has a certain viscosity. It is coated on the substrate and usually includes a composite part. It can composite another substrate and the coated substrate together. It has the advantages of not requiring drying equipment, low energy consumption, no solvents (hot melt adhesive is 100% solid component) and no pollution. Operators will not be exposed to a large amount of formaldehyde due to cleaning residual adhesive. Compared with traditional solvent-based and water-soluble adhesives, the coating process of professionally manufactured hot melt adhesive cloth-based tape coating machines has enviable advantages, effectively solves the inherent drawbacks of traditional processes, and is an ideal production tool for the renewal of the coating and composite industry.

[0003] A hot melt adhesive cloth-based tape coating mechanism disclosed in the Chinese utility model patent application disclosure CN220590573U solves the problem of uneven adhesive discharge during coating, but the hot melt adhesive cloth-based tape coating mechanism still has the following disadvantages: First, after coating is completed, a winding roller is required to roll up the coated tape, and since the hot melt adhesive needs to maintain a sufficient temperature before coating to prevent the hot melt adhesive from solidifying, the hot melt adhesive has not been completely air-dried after coating, which will cause the hot melt adhesive to become plastic when rolling up, making the hot melt adhesive on the surface of the cloth-based tape uneven; Second, after the collecting roller rolls up the cloth-based tape, the cloth-based tape needs to be manually removed from the collecting roller, and since the collecting roller needs to be fixed, the collecting roller is not easy to disassemble, and the rolled cloth-based tape is also not easy to remove.

The blocking plate 12 is located at the outer end of the first driven rod 11 and is fixedly connected to the first driven rod 11. The blocking plate 12 is located between the conveyor belt 13 and the synchronous belt 10. The inner wall of the conveyor belt 13 is rotatably connected with a condenser tube 15. There are two condenser tubes 15. The outer end of the condenser tube 15 is fixedly connected to the inner wall of the body 1. An electric heating wire is provided inside the glue storage box 3. A glue storage box door 4 is provided on the top of the glue storage box 3. The top of the glue storage box door 4 is fixedly connected to the glue storage box door A handle 5 is provided at the bottom left of the glue storage box 3, a glue feeding plate 7 is provided on the left side wall of the top plate 2, the glue feeding plate 7 is inclined with the left side lower and the right side higher, the glue feeding plate 7 is located below the glue feeding plate 6, the conveyor belt 13 is located directly below the glue feeding plate 7, a first motor 9 is fixedly installed on the back of the body 1, the first motor 9 is connected to the rotating rod 8 in a transmission manner, both ends of the first driven rod 11 and the second driven rod 14 are connected to the inner wall of the body 1 in a rotation manner, the blocking plate 12 is annular, the major diameter of the blocking plate 12 is greater than the major diameter of the conveyor belt 13 and the synchronous belt 10, the condenser 15 Both ends of the machine body 1 are fixedly connected with condensation boxes 16, and the two condensation boxes 16 are respectively located on the front and back of the machine body 1. The top of the condensation box 16 on the back is fixedly connected with a liquid injection pipe 17, and the bottom of the condensation box 16 on the front is fixedly connected with a liquid discharge pipe 18.

[0027] During use, after coating is completed, a take-up roller is required to roll up the coated tape. Since the hot melt adhesive needs to maintain a sufficient temperature before coating to prevent the hot melt adhesive from solidifying, the hot melt adhesive has not been completely air-dried after coating, which will cause the hot melt adhesive to become plastic when rolling up the adhesive, making the hot melt adhesive on the surface of the cloth-based adhesive tape uneven. Therefore, there is a hot melt adhesive cloth-based adhesive tape coating mechanism. When the adhesive tape needs to be coated, the adhesive tape is wound around the outer end of the rotating rod 8. At this time, the first motor 9 is started, and the rotating rod 8 starts to rotate. Through the cooperation of the first driven rod 11 and the synchronous belt 10, the first driven rod 11 can drive the second driven rod 14 As the conveyor belt 13 starts to rotate, the adhesive tape flows under the adhesive plate 7 through the conveyor belt 13, and the adhesive storage box 3 starts to discharge adhesive. The hot melt adhesive flows from the adhesive outlet 6 through the adhesive plate 7 to the adhesive tape. At this time, the bellows 20 is opened, and air begins to flow from both ends to the middle, so that the surface of the hot melt adhesive can be quickly dried. The condenser 15 is provided at the bottom of the conveyor belt 13, so that the temperature of the hot melt adhesive can be reduced and the solidification speed can be accelerated, so that the applied hot melt adhesive can be quickly cooled and solidified, and the hot melt adhesive can be prevented from being deformed when being rolled, resulting in uneven hot melt adhesive. Subsequently, the adhesive tape after the hot melt adhesive is solidified is wound up through the winding rod 24 in cooperation with the third motor 25.

[0028] Embodiment 2:

[0029] See also Figures 1 to 5The utility model provides a technical solution: a hot melt adhesive tape coating mechanism, the inner wall of the body 1 is rotatably connected with a threaded rod 22 and a winding rod 24, the threaded rod 22 is located directly above the winding rod 24, and the threaded rod 22 is located on the left side of the conveyor belt 13, and a second motor 23 and a third motor 25 are fixedly installed on the back of the body 1, the second motor 23 is transmission-connected with the threaded rod 22, and the third motor 25 is transmission-connected with the winding rod 24, the outer end of the threaded rod 22 is threadedly connected with a slider 30, and the bottom of the slider 30 is fixedly connected with a connecting plate 29, the connecting plate 29 is square, and the bottom of the connecting plate 29 is fixedly connected with a push plate 26, the push plate 26 is annular, and the push plate 26 is slidably connected with the winding rod 24, and the outer end of the push plate 26 is fixedly connected with a first electric telescopic rod 27, and the first electric telescopic rod 27 has three, and the telescopic end of the first electric telescopic rod 27 is fixedly connected with a card plate 28, and the first electric telescopic rod 27 is circular on the push plate 26 The front of the machine body 1 is provided with a discharge port 31, which is circular, has a diameter greater than the major diameter of the push plate 26, and has the same center as the coiling rod 24. The inner side wall of the front of the machine body 1 is fixedly connected with a connecting block 32, and there are two connecting blocks 32, which are symmetrically distributed with respect to the coiling rod 24. The inner side wall of the connecting block 32 is fixedly installed with a second electric telescopic rod 33, and the telescopic end of the second electric telescopic rod 33 is fixedly connected to the inner side wall of the connecting block 32. There is a fixed block 34, which is in a semicircular shape. The inner wall of the fixed block 34 is tightly attached to the outer wall of the coiling rod 24. The fixed block 34 is rotatably connected to the coiling rod 24. The bottom of the body 1 is fixedly connected to a connecting rod 35.

By setting the diameter of the discharge port 31 larger than the large diameter of the push plate 26, the hot melt adhesive cloth-based tape coating mechanism has the effect of quickly removing the rolled tape, saving time, and facilitating use.
