Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology, and in particular to a uniform adhesive tape coating device. Background Technology

[0002] Adhesive tape is an item composed of a substrate and an adhesive, which uses its unique adhesive properties to connect two or more unconnected objects together. The substrate of adhesive tape can be paper, plastic, cloth, metal foil, or composite materials, while the adhesive is usually a layer of binder coated on the substrate. The earliest adhesives came from animals and plants, but modern adhesives widely use various polymers. Adhesive tape has a wide range of applications, including packaging, sealing, fixing, insulation, and marking. The manufacturing process of adhesive tape involves the application of adhesive.

[0003] In existing adhesive coating processes, some small factories cannot control the amount of adhesive flowing out, which may result in uneven coating of the substrate, affecting the bonding between the substrate and the adhesive, and consequently impacting the quality of the tape. Furthermore, existing adhesives generally rely on natural air drying without a drying mechanism, which may fail to remove residual solvents and moisture from the tape, potentially affecting the tape's bonding strength and stability. Additionally, if the residual moisture and solvent on the tape are not dried, it cannot be processed immediately, indirectly affecting production efficiency. Therefore, a uniform tape adhesive coating device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a uniform adhesive tape coating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform adhesive tape coating device, comprising a worktable, a conveying assembly inside the worktable, an adhesive box fixedly installed on the top of the worktable, an extrusion mechanism on the adhesive box, a rotating rod rotatably installed inside the worktable, an adhesive roller fixedly installed on the rotating rod, a drying hood fixedly installed on the top of the worktable, a rotating shaft rotatably installed inside the drying hood, fan blades fixedly installed on the rotating shaft, and a heating block fixedly installed inside the drying hood.

[0006] Preferably, a connecting plate is fixedly installed on the outer side of the workbench, and an unwinding roller is rotatably installed inside the connecting plate. One end of the substrate is fixedly installed on the unwinding roller.

[0007] Preferably, a first motor is fixedly installed on the other side of the workbench, the rotating rod is fixedly installed on the output end of the first motor, a second motor is fixedly installed on the upper surface of the drying hood, and the rotating shaft is fixedly installed on the output end of the second motor.

[0008] Preferably, the upper surface of the drying hood is provided with an air inlet, and the bottom of the drying hood is provided with an air outlet.

[0009] Preferably, the extrusion mechanism includes a bracket fixedly mounted on the glue box, an electric telescopic rod fixedly mounted on the upper surface of the bracket, an extrusion plate slidably mounted inside the glue box, and the extrusion plate fixedly mounted on the output end of the electric telescopic rod.

[0010] Preferably, the glue box has a glue outlet at the bottom, and a guide block is fixedly installed inside the glue box.

[0011] Preferably, the glue box has a groove, and a slider is fixedly installed on one side of the extrusion plate, the slider being slidably installed in the groove.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, by setting up an extrusion mechanism, the electric telescopic rod is activated, which drives the extrusion plate to move inside the glue box. The extrusion plate moves and extrudes the glue in the glue box, so that the glue in the glue box can be extruded from the glue outlet onto the glue coating roller at a uniform speed.

[0014] In this invention, by setting up a structure including a rotating shaft, fan blades, heating block, second motor, and air inlet, the heating block and the second motor are activated. The heating block generates heat, and the second motor drives the fan blades to rotate, blowing the heat generated by the heating block onto the substrate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] like Figure 1-4 As shown, this embodiment provides a uniform tape adhesive coating device, including a workbench 1, a conveying assembly 2 inside the workbench 1, an adhesive box 3 fixedly installed on the top of the workbench 1, an extrusion mechanism 4 on the adhesive box 3, a rotating rod 5 rotatably installed inside the workbench 1, an adhesive roller 6 fixedly installed on the rotating rod 5, a drying hood 7 fixedly installed on the top of the workbench 1, a rotating shaft 8 rotatably installed inside the drying hood 7, a fan blade 9 fixedly installed on the rotating shaft 8, a heating block 10 fixedly installed inside the drying hood 7, a connecting plate 11 fixedly installed on the outside of the workbench 1, an unwinding roller 12 rotatably installed inside the connecting plate 11, one end of a substrate 13 fixedly installed on the unwinding roller 12, a first motor 14 fixedly installed on the other side of the workbench 1, the rotating rod 5 fixedly installed at the output end of the first motor 14, a second motor 15 fixedly installed on the upper surface of the drying hood 7, the rotating shaft 8 fixedly installed at the output end of the second motor 15, an air inlet 16 opened on the upper surface of the drying hood 7, and an air outlet 17 opened at the bottom of the drying hood 7.

[0023] The front-end machine is activated, pulling the substrate 13. The substrate 13 moves on the conveyor assembly 2, simultaneously driving the extrusion mechanism 4. The extrusion mechanism 4 controls the glue in the glue box 3 to be evenly extruded onto the coating roller 6, which in turn drives the first motor 14. The first motor 14 drives the rotating rod 5 to rotate, which in turn drives the coating roller 6 to rotate. The rotation of the coating roller 6 applies the glue to the substrate 13. This setup ensures even application of glue to the substrate 13, preventing uneven glue application that could affect product quality. Then, the heating block 10 and the second motor 15 are activated. The heating block 10 generates heat, which in turn drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the fan blades 9 to rotate, which in turn draws air in through the air inlet 16 and blows the heat generated by the heating block 10 out through the air outlet 17 onto the substrate 13. This dries the residual solvent and moisture on the substrate 13, increasing the bonding strength and stability of the finished substrate 13. At the same time, the finished substrate 13 can be processed immediately, improving production efficiency.

[0024] In this embodiment of the utility model, specifically, the extrusion mechanism 4 includes a bracket 41 fixedly installed on the glue box 3, an electric telescopic rod 42 fixedly installed on the upper surface of the bracket 41, an extrusion plate 43 slidably installed inside the glue box 3, the extrusion plate 43 fixedly installed at the output end of the electric telescopic rod 42, a glue outlet 44 opened at the bottom of the glue box 3, a guide block 45 fixedly installed inside the glue box 3, a sliding groove 46 opened inside the glue box 3, and a slider 47 fixedly installed on one side of the extrusion plate 43, the slider 47 slidably installed in the sliding groove 46;

[0025] To ensure that the glue in the glue box 3 is evenly squeezed onto the glue coating roller 6, the electric telescopic rod 42 is activated. The electric telescopic rod 42 drives the extrusion plate 43 to move inside the glue box 3. The extrusion plate 43 moves and squeezes the glue in the glue box 3, thereby squeezing the glue in the glue box 3 evenly from the glue outlet 44 onto the glue coating roller 6. The guide block 45 is set to facilitate the flow of glue into the glue outlet 44. The chute 46 and the slider 47 are set to restrict the position of the extrusion plate 43, so that the extrusion plate 43 only moves in the vertical direction of the chute 46. When glue needs to be added, the extrusion plate 43 can be moved outside the glue box 3 to add glue.

[0026] Working principle: During use, the front-end machine is started, pulling the substrate 13. The substrate 13 moves on the conveyor assembly 2. Simultaneously, the electric telescopic rod 42 is activated, driving the extrusion plate 43 to move within the glue tank 3. The extrusion plate 43 extrudes the glue in the glue tank 3, uniformly squeezing the glue from the outlet 44 onto the coating roller 6. Then, the first motor 14 is started, driving the rotating rod 5 to rotate. The rotation of the rotating rod 5 drives the coating roller 6 to rotate, thus applying the glue to the substrate 13. This setup allows for even application of adhesive to the substrate 13, preventing uneven application that could affect product quality. Then, the heating block 10 and the second motor 15 are activated. The heating block 10 generates heat, which in turn drives the rotating shaft 8 to rotate. The rotating shaft 8 then drives the fan blades 9 to rotate, blowing the heat generated by the heating block 10 onto the substrate 13. This effectively dries any residual solvent and moisture on the substrate 13, increasing the bonding strength and stability of the finished substrate 13. Simultaneously, the finished substrate 13 can be processed immediately, improving production efficiency.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
