Description

Technical Field

[0001] This utility model relates to the technical field of membrane composite equipment, specifically to a membrane composite equipment that can block vibration. Background Technology

[0002] Membrane lamination equipment is an automated device that bonds membrane materials to sheet materials. It mainly includes an unwinding roller, a coating roller, a first pressure roller, a second pressure roller, and a traction mechanism. A gap is formed between the first and second pressure rollers to allow the sheet material to pass through. To ensure that the sheet material can pass through the gap smoothly, the first pressure roller is usually designed to float slightly up and down relative to the second pressure roller. During production, the membrane material output from the unwinding roller passes through the coating roller, guide roller, first pressure roller, gap, and traction mechanism in sequence. The coating roller is used to apply adhesive to one side of the first membrane material. The first pressure roller bonds the adhesive-coated side of the first membrane material to the upper surface of the sheet material to complete the lamination operation.

[0003] However, due to the drop caused by the first pressure roller floating up and down during each plate entry and exit gap, the film material is frequently tensioned or loosened, causing the film material to shake and the shaking is transmitted to the coating roller, ultimately resulting in transverse adhesive marks on the film material during coating. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a film lamination device that blocks vibration, preventing the vibration of the film from being transmitted to the coating roller, thereby avoiding lateral adhesive marks on the film during coating.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A membrane composite device with vibration damping function includes a first unwinding roller, a coating roller, a guide roller, a first pressure roller, a second pressure roller, and a traction mechanism.

[0007] The first pressure roller is positioned above the second pressure roller, and a gap is formed between the first pressure roller and the second pressure roller for the sheet material to pass through. The first pressure roller can float up and down relative to the second pressure roller.

[0008] The first film material output from the first unwinding roller passes sequentially through the coating roller, guide roller, first pressure roller, gap, and traction mechanism. The coating roller is used to coat the adhesive onto one side surface of the first film material, and the first pressure roller adheres the adhesive-coated side of the first film material to the upper surface of the board.

[0009] The guide roller is provided with a negative pressure cavity, and the outer peripheral surface of the guide roller is provided with a number of adsorption holes that communicate with the negative pressure cavity. The adsorption holes can adsorb the other side of the first film material.

[0010] By setting up a first unwinding roller, a coating roller, a guide roller, a first pressure roller, a second pressure roller, and a traction mechanism, the guide roller is provided with a negative pressure chamber, and the outer surface of the guide roller is provided with adsorption holes. During production, the sheet passes through the gap between the first pressure roller and the second pressure roller. The first film material output from the first unwinding roller passes through the coating roller, the guide roller, the first pressure roller, the gap, and the traction mechanism in sequence. The coating roller applies adhesive to one side of the first film material, and the adsorption holes adsorb the other side of the first film material. The first pressure roller attaches the adhesive-coated side of the first film material to the upper surface of the sheet. By using the adsorption holes to adsorb the first film material, the vibration of the first film material between the guide roller and the first pressure roller is prevented from being transmitted to the coating roller. Thus, when the coating roller applies the coating, the transverse adhesive marks on the first film material are avoided.

[0011] As a preferred embodiment, the guide roller is an active guide roller, which is connected to a rotating device, and the rotational speed of the active guide roller is less than the traveling speed of the first film material.

[0012] As a preferred embodiment, the guide roller is a driven guide roller.

[0013] As a preferred embodiment, the wrapping angle β of the first film material wrapped around the guide roller is 60 degrees to 90 degrees.

[0014] As a preferred embodiment, the wrapping angle β of the first film material wrapped around the guide roller is 65 degrees to 75 degrees.

[0015] As a preferred embodiment, the traction mechanism has two traction rollers arranged vertically.

[0016] As a preferred embodiment, an automatic feeding mechanism is also included, which is located on the side of the gap away from the traction mechanism, and is used to transport the sheet metal into the gap.

[0017] As a preferred embodiment, the system also includes a second unwinding roller, through which the second film material output from the second unwinding roller passes sequentially through a second pressure roller, a gap, and a traction mechanism, with the second pressure roller attaching the second film material to the lower surface of the board.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, by setting up a first unwinding roller, a coating roller, a guide roller, a first pressure roller, a second pressure roller, and a traction mechanism, the guide roller is provided with a negative pressure chamber and an adsorption hole is provided on the outer peripheral surface of the guide roller. During production, the sheet passes through the gap between the first pressure roller and the second pressure roller. The first film material output from the first unwinding roller passes through the coating roller, the guide roller, the first pressure roller, the gap, and the traction mechanism in sequence. The coating roller applies adhesive to one side of the first film material, and the adsorption hole adsorbs the other side of the first film material. The first pressure roller adheres the adhesive-coated side of the first film material to the upper surface of the sheet. By using the adsorption hole to adsorb the first film material, the vibration of the first film material between the guide roller and the first pressure roller is prevented from being transmitted to the coating roller, thereby avoiding the formation of lateral adhesive marks on the first film material during coating by the coating roller.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the position 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 this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figure 1 As shown, this utility model discloses a membrane composite equipment with vibration blocking function, including a first unwinding roller 10, a coating roller 11, a guide roller 12, a first pressure roller 13, a second pressure roller 14, and a traction mechanism 16.

[0026] The first pressure roller 13 is located above the second pressure roller 14, and a gap 15 is formed between the first pressure roller 13 and the second pressure roller 14 for the plate 20 to pass through. The first pressure roller 13 can float up and down relative to the second pressure roller 14.

[0027] The first film material 17 output from the first unwinding roller 10 passes sequentially through the coating roller 11, the guide roller 12, the first pressure roller 13, the gap 15, and the traction mechanism 16. The coating roller 11 is used to coat the adhesive onto one side surface of the first film material 17, and the first pressure roller 13 adheres the adhesive-coated side of the first film material 17 to the upper surface of the plate 20.

[0028] The guide roller 12 is provided with a negative pressure chamber 121, which is connected to an external negative pressure device (not shown). The outer peripheral surface of the guide roller 12 is provided with a plurality of adsorption holes that are connected to the negative pressure chamber 121. The adsorption holes can adsorb the other side of the first film material 17.

[0029] The guide roller 12 is an active guide roller 12, which is connected to a rotating device (not shown). The rotating device drives the active guide roller 12 to rotate, and the rotational speed of the active guide roller 12 is less than the traveling speed of the first film material 17. By using the active guide roller 12, the rotational speed of the active guide roller 12 is less than the traveling speed of the first film material 17. Combined with the adsorption holes to adsorb the first film material 17, it can generate resistance to the travel of the first film material 17, further isolating the vibration of the first film material 17 between the first pressure roller 13 and the guide roller 12. In addition, the rotational speed of the rotating device can be adjusted to regulate the rotational speed of the active guide roller 12, so that the traveling speed of the first film material 17 and the isolation of the vibration of the first film material 17 are optimal.

[0030] It should be noted that the guide roller 12 of this utility model can also be a driven guide roller 12, with the first film material 17 driving the driven guide roller 12 to rotate.

[0031] The coating angle β of the first film material 17 wrapped around the guide roller 12 is 60 degrees to 90 degrees. By setting the coating angle β of the first film material 17 wrapped around the guide roller 12 to 60 degrees to 90 degrees, the contact surface between the first film material 17 and the guide roller 12 is large enough, the adsorption effect of the guide roller 12 on the first film material 17 is better, and the blocking effect on the vibration of the first film material 17 is improved.

[0032] The coating angle β of the first film material 17 wrapped around the guide roller 12 is 65 degrees to 75 degrees, preferably 70 degrees.

[0033] The traction mechanism 16 has two traction rollers 161 arranged vertically, and the composite plate 20 and the first film 17 pass through the two traction rollers.

[0034] A first guide roller 18 is provided between the coating roller 11 and the first unwinding roller 10, and a second guide roller 19 is provided between the coating roller 11 and the guide roller 12. The first guide roller 18 and the second guide roller 19 are provided to facilitate the guidance of the first film material 17.

[0035] The present invention also includes an automatic feeding mechanism 21, which is located on the side of the gap 15 away from the traction mechanism 16. The feeding mechanism is used to transport the plate 20 to the gap 15.

[0036] The present invention also includes a second unwinding roller 30. The second film material 31 output from the second unwinding roller 30 passes sequentially through a second pressure roller 14, a gap 15, and a traction mechanism 16. The second pressure roller 14 adheres the second film material 31 to the lower surface of the plate 20. The second film material 31 can be a release film.

[0037] The working principle of this utility model (guide roller 12 is a driven guide roller 12):

[0038] The automatic feeding mechanism 21 inputs the sheet material 20 from one side of the gap 15 and outputs the sheet material 20 from the other side of the gap 15. Under the traction of the traction mechanism 16, the first film material 17 output from the first unwinding roller 10 passes through the coating roller 11, guide roller 12, first pressure roller 13, gap 15, and traction mechanism 16 in sequence. The coating roller 11 applies glue to one side of the first film material 17, and the adsorption holes on the guide roller 12 adsorb the other side of the first film material 17. The first pressure roller 13 attaches the glue-coated side of the first film material 17 to the upper surface of the sheet material 20. At the same time, the second film material 31 output from the second unwinding roller 30 passes through the second pressure roller 14, gap 15, and traction mechanism 16 in sequence. The second pressure roller 14 attaches the second film material 31 to the lower surface of the sheet material 20, thus completing the composite operation of the sheet material 20 with the first film material 17 and the second film material 31.

[0039] In summary, this utility model, by setting up a first unwinding roller 10, a coating roller 11, a guide roller 12, a first pressure roller 13, a second pressure roller 14, and a traction mechanism 16, provides a negative pressure chamber 121 within the guide roller 12 and adsorption holes on its peripheral outer surface. During production, the sheet material 20 passes through the gap 15 between the first pressure roller 13 and the second pressure roller 14, and the first film material 17 output from the first unwinding roller 10 sequentially passes through the coating roller 11, the guide roller 12, the first pressure roller 13, and the gap 15. 15. The traction mechanism 16, the coating roller 11 applies glue to one side of the surface of the first film material 17, the adsorption hole adsorbs the other side of the first film material 17, the first pressure roller 13 attaches the glue-coated side of the first film material 17 to the upper surface of the plate 20, and uses the adsorption hole to adsorb the first film material 17, thereby preventing the vibration of the first film material 17 between the guide roller 12 and the first pressure roller 13 from being transmitted to the coating roller 11, and thus preventing the first film material 17 from having transverse adhesive marks when the coating roller 11 applies the coating.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
