DETAILED DESCRIPTION

[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Example 1:

[0030] A QR code marking machine that allows for easy replacement of the take-up reel, such as Figures 1-4 As shown, the device includes a marking machine 1, with a rewinder 2 fixedly connected to one side. The rewinder 2 is equipped with a winding mechanism 3, which includes a main winding shaft 301. One end of the main winding shaft 301 is rotatably connected to a rotating rod 304, and one end of the rotating rod 304 is rotatably connected to a secondary winding shaft 305. A scraper 306 is slidably connected to one side of the secondary winding shaft 305, and a pressure spring 310 is provided on the top of the scraper 306. The rotatable connection between the main winding shaft 301, the rotating rod 304, and the secondary winding shaft 305 allows the user to easily replace the winding shaft without complicated operations or tools. Under the action of the pressure spring 310, the scraper 306 on one side of the secondary winding shaft 305 is tightly attached to the surface of the secondary winding shaft 305. The user only needs to manually rotate the secondary winding shaft 305, and the scraper 306 will gently scrape across the surface of the paper roll to effectively remove the label for easy use.

[0031] See Figure 1 , Figure 2 and Figure 3 The scraper 306 has a triangular cross-section. The narrow end of the scraper 306 abuts against the surface of the sub-roller 305. This abuts against the surface of the sub-roller 305, ensuring the stability and accuracy of the scraper 306 during the scraping process. It also allows the scraper 306 to fit tightly against the surface of the sub-roller 305, avoiding problems such as uneven scraping or difficulty in label removal caused by the scraper loosening or shifting.

[0032] See Figure 1 , Figure 2 and Figure 3 The rewinder 2 has a socket 202 on its shaft 201 and a first slot 307 on its main rewind 301. The use of the socket 202 and the first slot 307 makes it easier and more convenient to replace the main rewind 301. When the user needs to replace the rewind shaft, he / she only needs to pull the fixing rod 4 out of the socket 202 and the first slot 307, and then the rewind mechanism 3 can be easily removed from the rewinder 2 and replaced with a new rewind mechanism 3.

[0033] See Figure 1 , Figure 2 and Figure 3 A fixing rod 4 is inserted into the socket 202 and the first slot 307. The fixing rod 4 is U-shaped. The U-shaped fixing rod 4 makes the insertion process simpler and more convenient. The user only needs to align the two arms of the fixing rod 4 with the socket 202 and the first slot 307 respectively, and then push gently to complete the fixing, which improves the ease of operation of the device.

[0034] Referring to Figure 1 , Figure 2 and Figure 3 , the second slot 308 is fixedly connected with the pressing rod 309 inside, and the cooperation of the second slot 308 and the pressing rod 309 makes the scraping process of the scraper 306 more smooth and uniform. Since the pressing rod 309 fixes the paper roll on the auxiliary spool 305, the scraper 306 can scrape the label more easily when scraping.

[0035] Referring to Figure 1 , Figure 2 and Figure 3 , one end of the speed regulation crank 203 of the rewinder 2 is fixedly connected with the cross rod 204, and the cross rod 204 abuts against the rotating rod 304. The abutment of the cross rod 204 and the rotating rod 304 further enhances the structural stability and transmission efficiency of the equipment. Since the cross rod 204 abuts against the rotating rod 304 tightly, when the speed regulation crank 203 is rotated, power can be transmitted to the rotating rod 304 and the auxiliary spool 305 more stably and efficiently, thereby ensuring the stability and reliability of the equipment during high-speed operation.

[0036] The implementation principle of the utility model is as follows: first, the marking machine 1 is responsible for printing a two-dimensional code label, and the printed label is automatically wound onto the main spool 301 by the rewinder 2 to form a tight paper roll;

[0037] The fixed rod 4 is inserted and fixed through the jack 202 and the first slot 307, so that the position of the main spool 301 can be fixed to ensure its normal working process. The second slot 308 and the pressing rod 309 on the auxiliary spool 305 are used to preliminarily fix the paper roll and ensure that one end of the scraper 306 can scrape the label. The speed regulation crank 203 and the cross rod 204 can drive the rewinder 2 to rotate under the drive of the rotating rod 304, thereby automatically adjusting the rotating speed of the rewinder 2.

[0038] When it is necessary to take the label from the paper roll, the user can manually rotate the auxiliary spool 305. The scraper 306 on one side of the auxiliary spool 305 tightly abuts against the surface of the auxiliary spool 305 under the action of the pressure spring 310. With the rotation of the auxiliary spool 305, the scraper 306 will gently scrape the surface of the paper roll to effectively scrape the label from the paper roll, which is convenient for taking.

[0039] Example two:

[0040] Referring to Figure 1 Figure 2 Figure 3 Figure 4 , the rewinder 2 is provided with a speed regulation knob 5, and the speed regulation knob 5 is provided with an identification 6 around. The identification 6 around the speed regulation knob 5 provides a clear speed reference for the user. The identification 6 usually represents different speed gears in the form of numbers, scales or colors, so that the user can intuitively understand the current rotating speed setting of the rewinder 2.

[0041] The implementation principle of the utility model is: first, rotate the speed knob 5 to make the speed can be set initially, the speed knob 5 and the mark 6 are used to adjust the working speed of the rewinder 2 conveniently.
