DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 5 A high-precision barcode printer wrinkle-proof belt device comprises a base 1, a supporting side plate 2 is fixedly connected to the base 1, a feeding roller 3 and a receiving roller 4 are rotatably connected to the supporting side plate 2, a printing mechanism 5 is fixedly connected to the bottom of the base 1, a rotating mechanism 6 is fixedly connected to both sides of the base 1, a tensioning assembly 7 is fixedly connected to the right side of the receiving roller 4, and a limiting assembly 8 for limiting the tensioning assembly 7 is rotatably connected to the rotating mechanism 6.

[0023] The high-precision anti-wrinkle belt device of the barcode printer in the utility model is similar in structure to the anti-wrinkle belt device of the existing barcode printer, such as the patent with announcement number CN215662533U discloses an anti-wrinkle belt device of a barcode printer. The main improvement of the utility model is that by setting the tensioning component 7, the tensioning component 7 can always support and tighten the back of the carbon ribbon on the side of the receiving roller 4 during the barcode printing process, so that the carbon ribbon is always in a tight state, thereby avoiding the wrinkles of the carbon ribbon, thereby avoiding the unclear barcode printing, wrong code, etc. Figures 1 to 5As shown, the anti-wrinkle belt device for high-precision barcode printers in the utility model, when in use, first pass the front end of the carbon ribbon through the tensioning assembly 7, and sequentially abut against the first rollers 604 on the two rotating mechanisms 6 on both sides of the base 1, and then connect to the receiving roller 4. At this time, release the restriction of the clamping plate 802 by tightening the bolt 801, and turn the clamping plate 802 to the surface of the first fixing block 601, so as to release the restriction on the tensioning assembly 7. Under the action of the first spring 707 and the second spring 708, the tensioning assembly 7 makes the first support plate 702 and the second support plate 704 and the second support plate 706 and the second support plate 707 and the second support plate 708. The plate 703 rotates upward around the first connecting rod 701, so that the second connecting rod 704 also rotates around the first connecting rod 701 until the second roller 709 rotatably connected to the second connecting rod 704 is in contact with the back of the carbon ribbon, and printing can begin normally. During the printing process, the second roller 709 is always subjected to the upward rotation force given by the first spring 707 and the second spring 708, so that after the carbon ribbon is relaxed, the second roller 709 continues to rotate upward, thereby tightening the carbon ribbon, thereby avoiding the occurrence of poor barcode printing effect.

[0024] like Figure 1 , Figure 2 or Figure 3 As shown, a non-slip sleeve 9 is fixedly connected to the surface of the receiving roller 4 .

[0025] Specifically, the anti-slip sleeve 9 increases the friction between the carbon ribbon and the receiving roller 4, making it easier to collect the carbon ribbon.

[0026] like Figure 3 As shown, there are two rotating mechanisms 6 , which are symmetrically arranged on both sides of the base 1 .

[0027] Specifically, a rotating mechanism 6 is provided on both sides, so that the carbon ribbon can pass through the printing mechanism 5 more smoothly, and there will be no friction between the carbon ribbon and the bottom or both sides of the base 1, thereby avoiding wrinkles of the carbon ribbon caused by friction.

[0028] like Figure 2 As shown, the rotating mechanism 6 includes a first fixed block 601 and a second fixed block 602 fixed on both sides of the base 1 , a rotating shaft 603 is rotatably connected between the first fixed block 601 and the second fixed block 602 , and a first roller 604 is fixedly connected to the rotating shaft 603 .

[0029] Specifically, the carbon ribbon is in contact with the surface of the first roller 604. When printing is in progress, the carbon ribbon is gradually collected on the receiving roller 4. During the movement of the carbon ribbon, the first roller 604 rotates along with the rotating shaft 603, and the carbon ribbon moves more smoothly, and it is less likely to generate friction and cause wrinkles in the carbon ribbon.

[0030] like Figure 4As shown, the tensioning assembly 7 includes a first connecting rod 701 fixed to the front end of the inner wall of the first fixed block 601 and the second fixed block 602, the first connecting rod 701 is rotatably connected to the first support plate 702 and the second support plate 703, the output ends of the first support plate 702 and the second support plate 703 are fixedly connected to the second connecting rod 704, the middle position of the first connecting rod 701 is fixedly connected to the first sleeve 705, the outer side of the first sleeve 705 is fixedly connected to the second sleeve 706, the left side of the second sleeve 706 is fixedly connected to the first spring 707, the right side of the second sleeve 706 is fixedly connected to the second spring 708, the output end of the first spring 707 is fixedly connected to the first support plate 702, the output end of the second spring 708 is fixedly connected to the second support plate 703, and the second connecting rod 704 is rotatably connected to the second roller 709.

[0031] Specifically, during the printing process, the second roller 709 is always subjected to the upward rotation force given by the first spring 707 and the second spring 708, so that after the carbon ribbon is relaxed, the second roller 709 continues to rotate upward around the first connecting rod 701 under the action of the first spring 707 and the second spring 708, thereby tightening the carbon ribbon again, thereby preventing the carbon ribbon from loosening and generating wrinkles.

[0032] like Figure 1 or Figure 5 As shown, the limiting assembly 8 includes a tightening bolt 801 threadedly connected to the upper surface of the first fixing block 601, and a clamping plate 802 is sleeved on the threaded rod of the tightening bolt 801.

[0033] Specifically, before installing the carbon ribbon, release the restriction of the clamping plate 802 by the tightening bolt 801, first press the first support plate 702 of the tensioning assembly 7 downward, so that the first support plate 702 is lower than the lower surface of the clamping plate 802, the first spring 707 and the second spring 708 store energy, rotate the clamping plate 802, so that the lower surface of the clamping plate 802 is placed on the surface of the first support plate 702, tighten the tightening bolt 801 again to fix the tensioning assembly 7, and facilitate the installation of the carbon ribbon. After the carbon ribbon is installed, the restriction on the tensioning assembly 7 can be released by performing the opposite operation, the first spring 707 and the second spring 708 release energy, so that the second roller 709 rotates upward until it is in contact with the back of the carbon ribbon, providing a certain support for the carbon ribbon.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
