BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 It is a side sectional view of the glass cloth gluing device provided by the utility model. DETAILED DESCRIPTION

[0013] REFERENCE Figure 1 The utility model provides a kind of glass cloth gluing device, including rack 5, back pressure roller 1, coating wheel 2, glue applying wheel 3, glue tank 4, back pressure roller 1, coating wheel 2 and glue applying wheel 3 three axis parallel and are rotationally installed on rack 5, wherein the outer peripheral wall between coating wheel 2 and back pressure roller 1 outer peripheral wall has the gluing channel for glass cloth interference to pass, the outer peripheral wall of glue applying wheel 3 is attached with the outer peripheral wall of coating wheel 2, glue tank 4 is fixed in the lower of glue applying wheel 3, and the bottom end of glue applying wheel 3 is immersed into the glue filled in glue tank 4.

[0014] It needs to be further explained that rotating motor is also fixed on rack 5, and rotating motor is driven to connect glue applying wheel 3 to drive glue applying wheel 3 rotation.

[0015] In the utility model, glue applying wheel 3 is driving wheel, coating wheel 2 is driven wheel, glass cloth passing through gluing channel is driven coating wheel 2 rotation by friction force, so as to ensure that the speed of coating wheel 2 is consistent with the speed of glass cloth, without additional adjustment, ensure the quality of glass cloth, in addition, the speed of rotating motor is adjustable, when glue applying wheel 3 rotates, glue in glue tank 4 is attached to glue applying wheel 3, when the linear speed of glue applying wheel 3 and coating wheel 2 is not consistent, there is relative speed difference between the two, glue on glue applying wheel 3 will be smeared on coating wheel 2, and glue is transferred to glass cloth by coating wheel 2, thereby completing the gluing process of glass cloth.

[0016] In the above embodiment, the upper glue wheel 3 is immersed in the glue tank 4, and the amount of glue carried by the upper glue wheel 3 rotating one end is certain. In the present application, the rotating speed of the rotating motor can be adjusted. When the rotating speed of the rotating motor driving the upper glue wheel 3 to rotate slows down, the contact length of the coating wheel 2 with the upper glue wheel 3 becomes longer when the upper glue wheel 3 rotates one circle, and the upper glue wheel 3 brings less glue to the coating wheel 2 per unit length. Conversely, when the rotating speed of the rotating motor driving the upper glue wheel 3 to rotate speeds up, the contact length of the coating wheel 2 with the upper glue wheel 3 becomes shorter when the upper glue wheel 3 rotates one circle, and the upper glue wheel 3 brings more glue to the coating wheel 2 per unit length. Thus, the amount of glue applied to the coating wheel 2 by the upper glue wheel 3 can be adjusted, and the amount of glue applied to the glass cloth by the coating wheel 2 can be adjusted.

[0017] It should be further explained that the coating wheel 2 comprises a rotating part rotationally connected with the rack 5 and a rubber part sleeved on the outer periphery of the rotating part. The rubber part improves the friction between the glass cloth and the coating wheel 2.

[0018] In the above embodiment, the width of the glue applying channel can be adjusted to meet the glue applying requirements of glass cloths with different thicknesses.

[0019] Specifically, the rack 5 comprises a first machine body 51 and a second machine body 52. The second machine body 52 is slidingly installed on the first machine body 51 in the second direction. A screw rod 53 is rotationally sleeved on the first machine body 51. The screw rod 53 is screwingly inserted into the second machine body 52 in the second direction. The back pressure roller 1 is rotationally connected with the first machine body 51. The upper glue wheel 3 and the coating wheel 2 are both rotationally connected with the second machine body 52.

[0020] The adjustment process of the width of the glue applying channel is as follows: the screw rod 53 is rotated. A guide groove extending along the length direction of the screw rod 53 is formed in the first machine body 51. The second machine body 52 has a guide part adapted to be inserted into the guide groove. When the screw rod 53 is rotated, the second machine body 52 cannot be rotated due to the restriction of the guide groove and the guide part. Since the screw rod 53 is screwingly inserted into the second machine body 52, the second machine body 52 will move along the length direction of the screw rod 53 when the screw rod 53 is rotated, so that the second machine body 52 drives the coating wheel 2 to move relative to the back pressure roller 1, thereby adjusting the width of the glue applying channel.

[0021] The glue applying device further comprises a backflow plate 6 fixed on the rack 5 and located below the upper glue wheel 3. The backflow plate 6 is arranged at different heights and has a low end smoothly connected with the edge of the glue tank 4, for recovering the glue falling from the coating wheel 2.

[0022] In order to avoid dust and impurities falling into the glue tank, the present application further comprises a dust cover detachably installed on the glue tank 4. The dust cover is made of transparent material (not shown in the figure).

[0023] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
