[0025] like Figure 1-5As shown, the utility model provides a tensioning mechanism for a material supply roll of a labeling machine, comprising a bottom plate 1, a mounting plate 2 is fixedly mounted on the bottom plate 1, a material tray mounting shaft 3 is rotatably mounted on the mounting plate 2, a friction wheel 4 is fixedly mounted on the material tray mounting shaft 3, a clamping belt 5 is sleeved on the friction wheel 4, and a material supply disk member 6 connected to the material tray mounting shaft 3 is fixedly mounted on one side of the friction wheel 4, a belt fixing assembly 100 rotatably connected to the mounting plate 2 and a support plate 7 are provided on one side of the clamping belt 5, the support plate 7 is arranged on one side of the belt fixing assembly 100, and the belt fixing assembly 100 A first hook spring 8 is hooked at one end, and the other end of the first hook spring 8 is hooked on the mounting plate 2. A resistance wheel 9 is fixedly installed at the other end of the belt fixing assembly 100. A top block 10 for moving the resistance wheel 9 is provided on one side of the resistance wheel 9. The top block 10 is fixedly connected to one end of the support plate 7. A label tensioning roller 11 is rotatably installed at the end of the support plate 7 away from the top block 10, and a second hook spring 12 is hooked on the support plate 7 near the top block 10. The other end of the second hook spring 12 is hooked on the mounting plate 2, and a paper guide roller 13 for guiding the label paper path is fixedly installed on the bottom plate 1.

[0026] In this embodiment, the belt fixing assembly 100 includes a positioning shaft 101 fixedly mounted on the mounting plate 2, a lever plate 102 rotatably mounted on the positioning shaft 101, and a belt fixing block 103 fixedly mounted on the lever plate 102, one end of the first hook spring 8 is hooked on one end of the lever plate 102, the resistance wheel 9 is connected to the other end of the lever plate 102, and both ends of the clamping belt 5 are fixedly arranged in the belt fixing block 103.

[0027] Specifically, the lever plate 102 is shaped like a boomerang, and its positioning shaft 101 is set in the middle section of the lever plate 102, so that after the resistance wheel 9 at one end of the lever plate 102 is turned, the belt fixing block 103 can move upward, causing the clamping belt 5 to loosen on the friction wheel 4, so that the feed disk 6 can rotate freely without resistance, which is beneficial to the forward movement of the label paper path; similarly, the other end of the lever plate 102 is subjected to the pulling force of the first hook spring 8, which can make the belt fixing block 103 move downward, causing the clamping belt 5 to clamp on the friction wheel 4, so that the feed disk 6 stops rotating freely due to resistance.

[0028] In this embodiment, a positioning groove 104 is provided on the belt fixing block 103 , a pressing block 105 fixedly connected to the belt fixing block 103 is provided in the positioning groove 104 , and both ends of the clamping belt 5 are pressed in the positioning groove 104 by the pressing block 105 .

[0029] Specifically, a clamping plate is also provided in the positioning groove 104, and the two ends of the clamping belt 5 are arranged between the clamping plate and the clamping block 105, and the belt fixing block 103 is penetrated by a first positioning hole and a second positioning hole which are connected to the positioning groove 104. The first positioning hole is used for installing bolts to tighten the clamping plate, and the second positioning hole is used for installing bolts to fix the clamping block 105, so that the two ends of the clamping belt 5 are tightly arranged between the clamping plate and the clamping block 105.

[0030] In this embodiment, a guide shaft 106 is fixedly mounted on one end of the lever plate 102, the inner ring side of the abutment wheel 9 is connected to the outer wall of the guide shaft 106, a guide groove 14 is opened on the surface of the mounting plate 2, and one end of the guide shaft 106 is arranged in the guide groove 14.

[0031] Specifically, one end of the guide shaft 106 passes through the abutment wheel 9 and extends into the guide groove 14 , so that when the abutment wheel 9 changes position, the guide shaft 106 can move in the guide groove 14 , thereby playing a role in guiding and stabilizing the rotation of the lever plate 102 .

[0032] In this embodiment, a support plate shaft 15 is fixedly installed on the mounting plate 2, one end of the support plate 7 is rotatably installed on the support plate shaft 15, an adjustment opening 16 is penetrated through the end of the support plate 7 close to the support plate shaft 15, a fastening bolt 17 is arranged in the adjustment opening 16, and the top block 10 is fixedly connected to the support plate 7 via the fastening bolt 17.

[0033] Specifically, the adjustment opening 16 is conducive to the position adjustment of the fastening bolt 17, and after adjustment, one end of the fastening bolt 17 passes through the adjustment opening 16 and is threadedly connected to the top block 10, thereby ensuring that the top block 10 can fit tightly on the support plate 7 and rotate together with the support plate 7 to ensure that the top block 10 can move the resistance wheel 9.

[0034] In this embodiment, two through-hole rods 18 are fixedly installed on the mounting plate 2, and the first hook spring 8 and the second hook spring 12 are respectively hooked on the corresponding through-hole rods 18. The through-hole rods 18 are used to ensure the stability of the first hook spring 8 and the second hook spring 12, thereby enabling the first hook spring 8 and the second hook spring 12 to perform elastic work normally.

[0035] The working principle and use process of the utility model are as follows: when in use, first remove the outer stopper on the feed tray 6, and then sleeve the label paper ring on the feed tray 6, and then fix the outer stopper after sleeve installation. During this period, the paper path on the label paper ring needs to be distributed on the paper guide roller 13 and the label tensioning roller 11 in a tensioned state, so that the label paper path is adjusted to a tensioned state through the label tensioning roller 11; after the labeling machine starts to run, when the label paper path moves on the label tensioning roller 11, the support plate 7 is subjected to the force of the second hook spring 12, which will cause a certain tension in the movement of the label paper path, and when the label paper path moves and drives the label tensioning roller 11 and the support plate 7 to move downward to a certain angle with the support plate shaft 15 as the center, the fixedly connected top block 10 will contact the contact wheel 9, causing the contact wheel 9 to be lifted and then drive the lever plate 102 and the belt fixing block 103 is lifted synchronously, so after the belt fixing block 103 is lifted, the holding belt 5 can loosen on the friction wheel 4, so that the feeding disk 6 can rotate freely without resistance at this time, and the rotation of the label paper circle is realized, which prompts the label paper path to make a conveying movement, and when the label paper path stops after conveying forward a certain distance, the support plate 7 is reset by the force of the second hook spring 12, and the lever plate 102 is reset by the force of the first hook spring 8 synchronously, so that after the holding belt 5 holds the friction wheel 4, the feeding disk 6 stops rotating freely with resistance, and the label paper path is reset by the label tensioning roller 11 and is in a tensioned state again. Therefore, when the labeling machine is working continuously, the reciprocating motion of the above-mentioned process ensures the stable transmission of the label paper path, avoids the easy wear of the existing friction block structure, and causes the tension control of the entire paper path to be poor, which affects the label feeding work.
