[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figures 1-6 As shown, a carbon ribbon coating device includes a coating frame 1, a winding frame 4 is fixedly installed on the right side of the coating frame 1, a coating structure is provided inside the coating frame 1, a limit adjustment component 2 is fixedly installed on the left part of the inner wall of the coating frame 1, and a flip winding component 3 is movably connected to the inner wall of the winding frame 4;

[0031] The limit adjustment assembly 2 includes a positioning roller 21. The front and rear ends of the positioning roller 21 are fixedly installed on the left part of the inner wall of the coating frame 1. The front and rear parts of the outer wall of the positioning roller 21 are movably connected to the limit ring 22. A movable groove 23 is opened on the top of the outer wall of the positioning roller 21. The front and rear parts of the inner wall of the movable groove 23 are slidably connected to the slides 24. The tops of the two slides 24 are fixedly connected to the tops of the inner walls of the two limit rings 22.

[0032] The flipping and winding assembly 3 includes two turntables 31, and the middle parts of the two turntables 31 on the side away from each other are rotatably connected to the rotating shaft 32, and the rear part of the outer wall of the rear rotating shaft 32 is fixedly connected to a rotating structure. The left and right parts of the two turntables 31 on the side away from each other are penetrated and rotatably connected to the rotating seat 33, and the four front and rear adjacent rotating seats 33 on the side away from each other are fixedly installed with cylinders 34, and the output ends of the four cylinders 34 penetrate the corresponding rotating seats 33 and are fixedly installed with conical heads 35, and the outer walls of the four front and rear adjacent conical heads 35 are in contact with the winding roller 36, and the outer walls of the two front rotating seats 33 are fixedly connected to the driving mechanism.

[0033] The limit adjustment component 2 can be used to mechanically limit the carbon ribbon to remain centered during transmission, thereby improving coating uniformity and winding regularity. In addition, the gear transmission structure can achieve synchronous adjustment of the limit rings 22 on both sides, eliminating the need for manual adjustment one by one, saving operation time. By flipping the winding component 3, the cylinder 34 can be used to drive the conical head 35 to fix the winding roller 36. In conjunction with the flipping of the turntable 31, it can automatically switch to another winding roller after a roll of carbon ribbon is full, achieving continuous winding. The overall degree of automation is high, and there is no need to manually replace the winding roller, which reduces downtime and improves production efficiency.

[0034] like Figure 3 and Figure 5 As shown, the front and rear parts of the inner wall of the movable groove 23 are rotatably connected with a bidirectional screw 25, the inner walls of the two slides 24 are threadedly connected to the front and rear parts of the outer wall of the bidirectional screw 25, the rear part of the outer wall of the bidirectional screw 25 is fixedly sleeved with a bevel gear 1 26, the rear position of the left part of the inner wall of the coating frame 1 is fixedly connected with a support frame 27, the inner wall of the support frame 27 is rotatably connected with an adjusting shaft 28, the bottom of the outer wall of the adjusting shaft 28 is fixedly sleeved with a bevel gear 2 29, and the outer surface of the bevel gear 1 26 is meshed with the outer surface of the bevel gear 2 29.

[0035] Rotate the adjusting shaft 28, which can drive the bevel gear 2 29 to rotate. The bevel gear 1 26 drives the bidirectional screw 25 to rotate by engaging with the bevel gear 29. The two slides 24 drive the two limiting rings 22 to move closer to or away from each other by being threadedly connected to the bidirectional screw 25, thereby limiting the carbon ribbons of different sizes.

[0036] like Figure 3 As shown, retaining rings 210 are fixedly mounted on the front and rear portions of the outer wall of the positioning roller 21 , and two limiting rings 22 are located between the two retaining rings 210 .

[0037] The retaining ring 210 can determine the maximum stroke of the two limiting rings 22 .

[0038] like Figure 3 As shown, the left and right positions of the top of the outer wall of the positioning roller 21 on both sides of the movable groove 23 are engraved with scale lines.

[0039] The scale lines facilitate workers to accurately adjust the limit ring 22.

[0040] like Figure 6 As shown, the driving mechanism includes gear 1 37 and gear 2 38. A servo motor 39 is fixedly connected to the front bottom of the front turntable 31. The output end of the servo motor 39 is fixedly connected to the inner wall of gear 1 37. The inner wall of gear 2 38 is fixedly connected to the outer wall of the front rotating base 33. The outer surface of gear 1 37 is meshed with the outer surface of gear 2 38.

[0041] The cylinder 34 extends out, and the conical head 35 is inserted into the holes at both ends of the winding roller 36 and fixed. The servo motor 39 drives the rotating base 33 to rotate through the gear transmission, and drives the winding roller 36 to rewind the carbon ribbon.

[0042] like Figure 4 and Figure 6 As shown, kiss roller structures 310 are movably connected to the middle of the opposite sides of the two turntables 31, and tension rollers 311 are rotatably connected to the left and right positions of the tops of the opposite sides of the two turntables 31.

[0043] The kiss roller structure 310 generates pressure on the winding roller 36 through the cylinder, making the winding surface flush with the end surface. The tension roller 311 can tighten the coil when the turntable 31 rotates, making it easier for the cutter structure to cut the carbon ribbon.

[0044] like Figure 1 、 Figure 2 and Figure 4 As shown, the rear part of the inner wall of the winding frame 4 is movably connected to the linear movable structure 5, and the front and rear positions of the bottom of the inner wall of the winding frame 4 are fixedly installed with door-shaped guide rods 6, and the outer sides of the two guide rods 6 are slidably connected to the moving frame 7, and the rear part of the lower end of the moving frame 7 is movably connected to the outer wall of the linear movable structure 5, and the front and rear positions of the right part of the inner wall of the moving frame 7 are rotatably connected to the adjustment plates 8, and the bottoms of the opposite sides of the two adjustment plates 8 are rotatably connected to the pressure rollers 9, and the tops of the opposite sides of the two adjustment plates 8 are fixedly installed with a cutting structure 10, and the middle position of the rear part of the inner wall of the moving frame 7 is rotatably connected to the electric cylinder 11, and the output end of the electric cylinder 11 is rotatably connected to the middle of the front side of the rear adjustment plate 8.

[0045] The electric cylinder 11 pushes the adjustment plate 8 to rotate, the pressure roller 9 presses down to fix the carbon ribbon, and the cutter structure 10 cuts the carbon ribbon, cooperating with the winding assembly to complete the material change.

[0046] like Figure 3 As shown, the right part of the inner wall of the movable frame 7 is movably connected with a height-adjustable roller 12.

[0047] On both sides of the roller 12, there are installed height adjustment components that can be adapted to the roller 12 in the prior art (for example, the first adjustment component and the second adjustment component described in the announcement number CN220991956U). In this case, the vertical height of the roller 12 can be adjusted during the implementation process. Both height adjustment components are located inside the movable frame 7;

[0048] In addition, the height adjustment component in this case is used to adjust the vertical height of the roller 12 during the implementation process. After the adjustment, the carbon ribbon can be straightened. The higher the inclination of the carbon ribbon, the tighter the carbon ribbon is stretched. During this process, the height of the roller 12 can be adjusted according to the looseness of the carbon ribbon, as long as the carbon ribbon is in a straight state and is not damaged.

[0049] The working principle of this utility model is as follows: After the ribbon is coated in the coating frame 1, it enters the limit adjustment assembly 2. The ribbon is then wound from the bottom of the positioning roller 21 into the winding frame 4, where it is positioned by the limit ring 22. The spacing between the two limit rings 22 can be adjusted in advance according to the ribbon size. Rotating the adjustment shaft 28 drives the second bevel gear 29. The first bevel gear 26 meshes with the second bevel gear 29, driving the bidirectional lead screw 25. The two slides 24, threadedly connected to the bidirectional lead screw 25, move the two limit rings 22 toward or away from each other, thereby securing ribbons of different sizes. To prevent the ribbon from straying during winding, the scale lines assist in achieving precise positioning. The output end of the cylinder 34, through the conical head 35, is inserted into the holes at the ends of the winding roller 36 to secure it. The servo motor 39 drives the rotating base 33 through a gear transmission, which in turn causes the two conical heads 35 to drive the winding roller 36 to wind the ribbon. The kiss roller structure 310 controls the winding pressure to ensure a smooth coil. When a roll of carbon ribbon is full, the rotating structure drives the two turntables 31 to rotate, and the turntable 31 drives the coil to rotate to the left of the cutter structure 10. The linear moving structure 5 drives the movable frame 7 to move left. After reaching the specified position, the electric cylinder 11 pushes the adjustment plate 8 to rotate, the pressure roller 9 presses down to fix the carbon ribbon, and the cutter structure 10 cuts the carbon ribbon, and cooperates with the flipping and winding component 3 to complete the material change.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
