DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Embodiment 1

[0027] Reference Figures 1-4 A tool, the structure mainly includes two support frames 1, and the opposite side inner wall of the two support frames 1 is provided with moving holes. The top of the two support frames 1 is fixedly installed with a support plate 7 through bolts or other fastening modes. In addition, it also includes cloth roller 2 and coating roller 3, and the two ends of the cloth roller 2 and the two ends of the coating roller 3 are installed on the two support frames 1 through bearings or other rotating connection modes.

[0028] The optimization tool further comprises a power mechanism installed on the top of the support plate 7. Specifically, the power mechanism comprises a driving motor 8 fixedly installed on one side of the top of the support plate 7, and a rotating shaft 9 fixedly installed on the output shaft of the driving motor 8, one end of the rotating shaft 9 being installed on the top of the support plate 7 through a bearing or other rotating connection. Two swing arms 10 are fixedly sleeved on the rotating shaft 9, and the two swing arms 10 are symmetrically distributed on the rotating shaft 9. The same connecting rod 11 is rotatably connected through the two swing arms 10, and the two ends of the connecting rod 11 are fixedly installed with connecting arms 12, and the two connecting arms 12 are connected with the back roller mechanism. When the driving motor 8 is started, the output shaft of the driving motor 8 drives the rotating shaft 9 to rotate, and in turn drives the two swing arms 10 to swing downward. In the process of swinging downward of the swing arms 10, the connecting rod 11 is driven to move in an arc shape downward. At this time, under the transmission action of the two connecting arms 12, the back roller mechanism can be driven to move downward, so as to realize the pressing of the base film, so that the base film can be in close contact with the coating film roller 3.

[0029] In order to increase the stability of the connecting rod 11 in the swinging process, two torsion springs 13 are symmetrically sleeved on the connecting rod 11. The two ends of the two torsion springs 13 are fixedly connected with the connecting rod 11 and the corresponding swing arm 10 respectively. When the swing arm 10 swings upward, there is relative rotation between the swing arm 10 and the connecting rod 11 at this time, so as to apply a torsion to the torsion spring 13, so that the torsion spring 13 has elastic potential energy. Therefore, when the swing arm 10 rotates downward, the elastic potential energy of the torsion spring 13 can be used to drive the connecting rod 11 to rotate reversely, so as to drive the two connecting arms 12 to rotate in the vertical direction.

[0030] The back roller mechanism comprises two limiting rods 4, and the two limiting rods 4 are fixedly installed in the corresponding support frame 1 through welding or other fastening. The moving plate 5 is slidably sleeved on the limiting rod 4, and the moving plate 5 is connected with the limiting mechanism. And the two moving plates 5 are rotatably connected with the same back roller 6 on the side close to each other, and the back roller 6 is used for pressing the base film. The two connecting arms 12 are rotatably connected with the back roller 6, so as to drive the back roller 6. The two limiting rods 4 are slidably connected with the corresponding moving plate 5, so as to limit the longitudinal sliding of the back roller 6, so that the back roller 6 can only move vertically. And under the transmission action of the two connecting arms 12, the back roller 6 can move longitudinally, so as to compact the base film.

[0031] The limiting mechanism comprises a supporting plate 14 slidingly sleeved on the limiting rod 4, and the supporting plate 14 is slidingly connected with the inner wall of the support frame 1. The top of the supporting plate 14 is symmetrically fixedly provided with two first electromagnets 15, and the bottom of the moving plate 5 is symmetrically fixedly provided with two limiting covers 16, and the limiting covers 16 are fixedly provided with second electromagnets 17. The side of the first electromagnet 15 and the second electromagnet 17 close to each other is provided with N-pole and S-pole respectively, so that the first electromagnet 15 and the second electromagnet 17 can be attracted after being powered on. One side of the supporting plate 14 is provided with an adjusting assembly which penetrates through the moving hole and extends to the outside of the support frame 1, and the adjusting assembly is connected with one side of the support frame 1. The height of the two first electromagnets 15 can be adjusted by operating the adjusting assembly to drive the supporting plate 14 to move longitudally.

[0032] The present application can be used in the field of film coating machine, and can also be used in other fields applicable to the present application.

[0033] Embodiment 2

[0034] Reference Figure 1 On the basis of embodiment one, a film coating machine back roller jumping precision optimization tool is improved: the adjusting assembly comprises a transmission plate 18 fixedly installed on one side of the supporting plate 14, and one side of the transmission plate 18 penetrates through the corresponding moving hole and extends to the outside of the support frame 1. The top of the transmission plate 18 is fixedly provided with a threaded ring 19, and a screw rod 20 is threadedly connected in the threaded ring 19. The bottom end of the screw rod 20 penetrates through the transmission plate 18 and extends below the transmission plate 18, and the bottom end of the screw rod 20 is installed on one side of the support frame 1 through a bearing or other rotating connection mode. Therefore, by rotating the screw rod 20, the transmission plate 18 can be driven to move longitudinally under the threaded transmission action of the threaded ring 19, and then the supporting plate 14 can be driven to move longitudinally. In this way, the height of the two first electromagnets 15 can be adjusted. By adjusting the height of the two first electromagnets 15, the descending height of the back roller 6 can be limited.

[0035] In use, first, according to the thickness of the base film, the height of the two first electromagnets 15 is adjusted by rotating the screw rod 20. Then, the driving motor 8 is started to drive the back roller 6 to move downward to press the base film. When the back roller 6 drives the moving plate 5 to move downward to the position corresponding to the first electromagnet 15 and the second electromagnet 17, the first electromagnet 15 and the second electromagnet 17 are powered on to be attracted, so as to stably brake the back roller 6, avoid the problem of jumping of the back roller 6, and realize stable clamping of the base film.

[0036] However, as known to those skilled in the art, the working principle and wiring method of the driving motor 8, the first electromagnet 15 and the second electromagnet 17 are common, which all belong to conventional means or common general knowledge, and will not be described here again, and those skilled in the art can make any selection according to their needs or convenience.
