[0037] Reference Figure 1 、 Figure 5 and Figure 6 According to the embodiment of the utility model, the reversing equipment for coating,

[0038] Support 100;

[0039] First traction roller 110, both ends of first traction roller 110 can be rotatably connected on support 100;

[0040] Second traction roller 120, second traction roller 120 is arranged above first traction roller 110, both ends of second traction roller 120 can be rotatably connected on support 100;

[0041] Support 200 and reversing roller 210, the length direction of reversing roller 210 is perpendicular to up-down direction, the length of reversing roller 210 is greater than the length of first traction roller 110 and second traction roller 120, both ends of reversing roller 210 can be rotatably connected on support 200, and the included angle is formed between reversing roller 210 and first traction roller 110, first traction roller 110, second traction roller 120 and reversing roller 210 are used to sequentially provide film winding, the middle part of support 200 can be rotatably connected on support 100, so that reversing roller 210 can rotate around its middle part, to change the angle of the included angle between reversing roller 210 and first traction roller 110.

[0042] It can be understood that first traction roller 110 and second traction roller 120 are parallel to each other, reversing roller 210 is perpendicular to up-down direction, and film is sequentially wound on first traction roller 110, second traction roller 120 and reversing roller 210. Since there is an included angle between reversing roller 210 and first traction roller 110, the film wound on reversing roller 210 will be diverted, thereby realizing the change of the moving direction of the film. The middle part of support 200 can be rotatably connected on support 100, and both ends of reversing roller 210 can be rotatably connected on support 200. When it is necessary to adjust the moving direction of the film, the operator only needs to move support 200, so that support 200 drives reversing roller 210 to rotate around its middle part, thereby changing the included angle between reversing roller 210 and first traction roller 110, to achieve the purpose of changing the moving direction of the film. The reversing equipment for coating can adjust the moving direction of the film, so that the coating production line can flexibly adjust the moving direction of the film according to different products, different process requirements or different production spaces, so that the coating production line can adapt to different production spaces, thereby facilitating the flexibility of the coating production line.

[0043] Reference Figure 1 、 Figure 6 and Figure 7In the embodiment of the utility model, first traction roller 110 and second traction roller 120 are parallel to left and right direction, and the film wound on first traction roller 110 and second traction roller 120 moves from back to front. Since the middle part of support 200 is rotatably connected to support frame 100, by rotating support 200, not only the size of the included angle between reversing roller 210 and first traction roller 110 can be changed, but also the orientation of the included angle between reversing roller 210 and first reversing roller 210 can be changed. When the included angle between reversing roller 210 and first reversing roller 210 is to the left, the moving direction of the film wound on first traction roller 110, second traction roller 120 and reversing roller 210 in turn changes from moving from front to back to moving from right to left. When the included angle between reversing roller 210 and first reversing roller 210 is to the right, the moving direction of the film wound on first traction roller 110, second traction roller 120 and reversing roller 210 in turn changes from moving from front to back to moving from left to right.

[0044] In the embodiment of the utility model, the angle-adjustable reversing roller 210 can adapt to different film materials, and by adjusting the angle, the turning effect can be optimized to ensure that the film is not affected by problems such as stretching deformation and wrinkling during turning, and the tension distribution during turning can be optimized to reduce film deformation and quality problems, which is conducive to improving the coating quality of the coating production line.

[0045] It should be explained that the included angle between reversing roller 210 and first traction roller 110 refers to the included angle between the axis of reversing roller 210 and the axis of first traction roller 110. Referring to Figure 7 , the included angle between the axis of reversing roller 210 and the axis of first traction roller 110 is defined as α. It is not difficult to understand that by changing the size of α, the moving direction of the film wound on reversing roller 210 can be changed.

[0046] Referring to Figure 1 and Figure 2The reversing device for coating further comprises a fastener 220, the support 100 is provided with a stud 130, the middle portion of the support base 200 is provided with an arc hole 230, the stud 130 is arranged in the arc hole 230, the fastener 220 is threadedly connected with the stud 130 and can abut against the support base 200, so that the support base 200 can be fixed on the support 100. As an embodiment of the utility model, the fastener 220 can be a nut. It can be understood that when the angle between the reversing roller 210 and the first traction roller 110 needs to be adjusted, the operator can unscrew the nut, so that the nut is separated from the abutment with the support base 200, at this time, the operator can rotate the support base 200 to rotate the reversing roller 210. After the angle between the reversing roller 210 and the first traction roller 110 is adjusted, the operator can screw the nut, so that the nut abuts against the support base 200, that is, the support base 200 is fixed on the support 100, so as to ensure that the reversing roller 210 does not shake in the coating process. The arc hole 230 is centered on the rotation axis of the support base 200.

[0047] Specifically, the support base 200 is provided with a plurality of arc holes 230, the support 100 is provided with a plurality of nuts, and the number of the fasteners 220 is plural. The plurality of nuts are respectively arranged in the plurality of arc holes 230, and the plurality of fasteners 220 are respectively threadedly connected with the plurality of studs 130. The plurality of arc holes 230 are distributed from outside to inside.

[0048] Reference Figure 1 and Figure 2 The support 100 is provided with an angle scale 140, and the support base 200 is provided with a first indication arrow 240. The first indication arrow 240 is used to cooperate with the angle scale 140 to indicate the angle between the reversing roller 210 and the first traction roller 110. It can be understood that the first indication arrow 240 can cooperate with the angle scale 140, and the angle scale 140 indicated by the first indication arrow 240 is the current angle between the reversing roller 210 and the first traction roller 110, so that the operator can know the current angle between the reversing roller 210 and the second traction roller 120 in real time, and the convenience of the operator in adjusting the reversing roller 210 is improved.

[0049] Reference Figure 1 and Figure 3The reversing device for coating further comprises two sliding blocks 150, the left and right ends of the reversing roller 210 are rotatably connected to the two sliding blocks 150 respectively, and the two sliding blocks 150 are slidably connected to the support 100 in the up-down direction, so as to change the distance between the first traction roller 110 and the second traction roller 120. It can be understood that, on the one hand, the left and right ends of the first traction roller 110 are slidably connected to the support 100 through the two sliding blocks 150 respectively, so that the distance between the first traction roller 110 and the second traction roller 120 can be adjusted, so that the operator can adjust the tension of the film wound around the first traction roller 110, the second traction roller 120 and the reversing roller 210 according to the production needs. On the other hand, the position of the first traction roller 110 in the up-down direction is adjustable, so that the operator can adjust the position of the first traction roller 110 according to the position of the film inlet, so that the first traction roller 110 can smoothly supply the film.

[0050] As an embodiment of the utility model, the reversing device for coating further comprises two sliding rails, the two sliding rails are parallel to the up-down direction, and the two sliding blocks 150 are slidably connected to the two sliding rails respectively. The reversing device for coating further comprises a connecting assembly 170, and the two sliding blocks 150 are fixed to the two sliding rails respectively through the connecting assembly 170. Specifically, referring to Figure 1 and Figure 3 The connecting assembly 170 comprises two bolts, threaded holes are formed in the two sliding blocks 150 respectively, the two bolts are threadedly connected to the two threaded holes respectively, and the two bolts can abut against the sliding rails respectively, so that the two sliding blocks 150 can be fixed to the two sliding rails. It can be understood that when the position of the first traction roller 110 needs to be adjusted, the operator can loosen the bolts on the sliding blocks 150, so that the two sliding blocks 150 can slide up and down on the two sliding rails respectively, so as to adjust the position of the first traction roller 110 in the up-down direction. After the position of the first traction roller 110 is adjusted, the operator tightens the bolts on the sliding blocks 150, and the bolts can abut against the sliding rails, that is, the friction between the sliding blocks 150 and the sliding rails is increased, so that the sliding rails are fixed on the sliding rails, that is, the position of the first traction roller 110 is fixed.

[0051] Referring to Figure 1 and Figure 4The reversing device for coating further comprises an offset amount detection assembly 300 arranged on the support 100, and the offset amount detection assembly 300 is used for detecting the offset amount of the film. It can be understood that in the present application, a qualified offset amount range is arranged in the offset amount detection assembly 300, and the offset amount detection assembly 300 is electrically connected with the traction mechanism in the coating production line. The offset amount detection assembly is used for detecting the offset amount of the film. When the offset amount detection assembly 300 detects that the offset amount of the film exceeds the qualified offset amount range, the offset amount detection assembly 300 will transmit a signal to the traction mechanism in the coating production line, and the traction mechanism will drive the film to move, so that the film can fall within the qualified offset amount range, which is beneficial to guarantee the coating quality of the coating production line.

[0052] As an embodiment of the present application, the reversing device for coating comprises two offset amount detection assemblies 300, and the two offset amount detection assemblies 300 are arranged on the left and right sides of the support 100 respectively. It can be understood that when the included angle between the reversing roller 210 and the first reversing roller 210 is towards the left, the offset amount detection assembly 300 on the left side can detect the offset amount of the film. When the included angle between the reversing roller 210 and the first reversing roller 210 is towards the right, the offset amount detection assembly 300 on the right side can detect the offset amount of the film.

[0053] Reference Figure 4 The offset amount detection assembly 300 comprises a first connecting piece 310, a second connecting piece 320, a third connecting piece 330 and an offset sensor 340. The upper end of the first connecting piece 310 is connected with the support 100. One end of the second connecting piece 320 is connected to the lower end of the first connecting piece 310 in a slidable manner. The third connecting piece 330 is rotatably connected to the other end of the second connecting piece 320. An avoiding slot is formed in the third connecting piece 330.

In the embodiment of the utility model, the offset sensor 340 is a distance sensor, and the distance sensor is used for detecting the distance from the distance sensor to the film, and the offset amount detection through the sensor is a common setting in the coating field, and will not be further described here.
