DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to the attached Figure 1 To the attached Figure 2 The present embodiment provides a composite device with a solvent-free coating function for mica tape, comprising a frame body 1, a coating mechanism 2 and a composite mechanism 3 provided on the frame body 1; a material roll 11 is rotatably provided on the frame body 1 for outputting the material to be coated; the coating mechanism 2 comprises a rotatably arranged coating roller 21 and a spray head 22 radially facing the coating roller 21, the spray head 22 being used to spray an adhesive onto the surface of the coating roller 21, the coating roller 21 rotating and pressing the material so that the adhesive is transferred and applied to the material the surface of the composite mechanism 3 includes a corresponding active pressing wheel 31 and a driven pressing wheel 32, a pressing area 33 is formed between the active pressing wheel 31 and the driven pressing wheel 32, the coated material is input to the lower side of the pressing area 33, and the coated surface of the coated material faces upward, and the corresponding bonding material is input to the upper side of the pressing area 33, the active pressing wheel 31 and the driven pressing wheel 32 simultaneously press the two materials in opposite directions, and the active pressing wheel 31 and the driven pressing wheel 32 rotate in opposite directions to each other, so that the two materials are compounded with each other and output to the pressing area 33. The composite device of this embodiment is provided with a coating mechanism 2 and a composite mechanism 3 on the frame body 1. Under the premise of using a solvent-free adhesive, the coating mechanism 2 adopts the cooperation of the coating roller 21 and the spray head 22 to achieve uniform coating of the adhesive on the material. The composite mechanism 3 adopts the cooperation of the active pressure wheel 31 and the driven pressure wheel 32 to directly composite the material output after the adhesive coating is completed, thereby improving the utilization rate of the adhesive, making the composite effect of the material more excellent, and improving the production efficiency of the composite device on the basis of simplifying the device structure.

[0024] The spray head 22 is arranged in a strip parallel to the coating roller 21 and has multiple spray holes 221 along its length. The multiple spray holes 221 can be connected to a channel connected to a single spray pump to simultaneously spray the adhesive onto the surface of the coating roller 21, ensuring uniform adhesion of the adhesive to the coating roller 21.

[0025] The two ends of the spray head 22 are respectively hinged on the frame body 1, so that the spray head 22 can be swung closer to or away from the coating roller 21. When the machine is stopped, if the coating roller 21 or the spray head 22 needs to be maintained, the spray head 22 can be swung away from the coating roller 21 to facilitate maintenance of the coating roller 21 or the spray head 22.

[0026] The spray head 22 is provided with an arc-shaped abutment block 222 on the side close to the coating roller 21. When the spray head 22 swings close to the coating roller 21 until the abutment block 222 abuts against the coating roller 21, the spray hole 221 is directly opposite the coating roller 21. The setting of the abutment block 222 limits the spraying distance between the spray head 22 and the coating roller 21. Setting a suitable spraying distance allows the spray head 22 to have an optimal spraying effect on the coating roller 21.

[0027] The coating mechanism 2 also includes an upper tensioning roller 23 and a lower tensioning roller 24 for simultaneously abutting the material and rotating in the same direction. A coating area 25 is formed between the upper tensioning roller 23 and the lower tensioning roller 24. The coating roller 21 extends into the coating area 25 to press and transport the material passing through the coating area 25. In this manner, the adhesive attached to the coating roller 21 can be more completely and evenly applied to the surface of the material.

[0028] The coating mechanism 2 also includes a coating driver 26 provided on the frame body 1. The coating driver 26 is used to drive the rotation of the coating roller 21. By driving the rotation of the coating roller 21, the coating roller 21 is driven to actively perform coating action on the surface of the material, making the coating effect of the coating mechanism 2 more stable and reliable.

[0029] The active pressure roller 31 is located below the lamination zone 33, while the passive pressure roller 32 is located above the lamination zone 33. The upper tension roller 23 is parallel to and beside the active pressure roller 31, allowing the coating material to be fed into the upper side of the active pressure roller 31 with the coated surface facing upward, thereby conforming to the material fed into the lower side of the passive pressure roller 32. The lamination of the upper and lower pressure rollers can reduce the spillage of adhesive during the lamination process.

[0030] The laminating mechanism 3 also includes a laminating driver 34 and an adjusting driver 35, which are mounted on the main frame 1. The laminating driver 34 is used to drive the rotation of the active pressing roller 31 to drive the laminating of the materials. The adjusting driver 35 is used to adjust the height of the driven pressing roller 32 to adjust the height of the laminating area 33. Adjusting the height of the laminating area 33 facilitates the installation of the materials on the laminating mechanism 3 before the device is started, and also allows for flexible adjustment of the laminating thickness of the materials.

[0031] The composite device also includes a reinforcement mechanism 4 provided on the frame body 1. The reinforcement mechanism 4 includes at least a first reinforcement roller 41 and a second reinforcement roller 42. When the composite material is output from the pressing area 33, the first reinforcement roller 41 and the second reinforcement roller 42 are respectively tensioned and pressed on the opposite sides of the composite material. In this manner of cooperation, after the composite material is output from the composite mechanism 3, while being air-dried and transported, the composite effect can be further enhanced by tensioning both sides of the composite material.

[0032] The composite device also includes a fine-tuning mechanism 5 provided on the frame body 1. The fine-tuning mechanism 5 includes at least a swinging fine-tuning roller 51. The fine-tuning roller 51 abuts against the composite material output from the reinforcement mechanism 4 to swing to tighten or relax the composite material, thereby flexibly adjusting the tension of the composite material to avoid the composite material being too tight or too loose in the device, thereby ensuring the composite effect of the device.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
