[0002] Food packaging bags are necessities in daily life. With the development of society, the concept of environmental protection has been deeply rooted in people's hearts. Paper food packaging bags have gradually replaced traditional plastic food packaging bags. However, paper packaging bags also have disadvantages, that is, they are not wear-resistant and are prone to wear and tear after long-term use. In order to improve this phenomenon and improve the wear resistance of paper food packaging bags, most food packaging bags are now made of wear-resistant materials such as kraft paper.
[0003] In daily life, paper food packaging bags made of wear-resistant materials are mostly sold as food packaging bags. When using, the food packaging bags need to be torn off the food packaging bag roll. However, food packaging bags made of wear-resistant materials such as kraft paper have greater toughness and require greater force. They are easy to tear and deviate when tearing, causing the food packaging bags to be damaged and affecting their use. In view of this, we propose a wear-resistant food packaging bag.

[0022] like Figures 1 to 4 As shown, the utility model relates to a wear-resistant food packaging bag, comprising a food packaging bag roll 1 and a cutting mechanism 2 sleeved on the surface of the food packaging bag roll 1. It is worth noting that the food packaging bag roll 1 is made of wear-resistant material.
[0023] Specifically, Figure 1 , Figure 2 As shown, the cutting mechanism 2 includes a sleeve 201 with an open end, a rotating shaft 202 and a cutter 203; the sleeve 201 is sleeved on the surface of the food packaging bag roll 1, the rotating shaft 202 is arranged on the inner wall of the sleeve 201, and one end of the rotating shaft 202 is fixedly connected to the inner wall of the closed end of the sleeve 201, the food packaging bag roll 1 is sleeved on the surface of the rotating shaft 202, a through groove 2011 is opened on one side of the sleeve 201, the cutter 203 is in an arc shape, and the cutter 203 is movably connected to the top outer wall of one side of the sleeve 201, and the cutter 203 is connected to the sleeve 2 01 is provided with an upwardly curved toggle plate 209; the food packaging bag on the food packaging bag roll 1 is pulled out from the through slot 2011 on one side of the sleeve 201, and the food packaging bag roll 1 rotates on the rotating shaft 202 at this time, and the cutter 203 is pushed downward by the toggle plate 209 so that the blade of the cutter 203 contacts the end of the food packaging bag on the food packaging bag roll 1, and the toggle plate 209 is pressed with a finger to tear the food packaging bag upward along the blade of the cutter 203, so that the food packaging bag on the food packaging bag roll 1 can be torn off.
[0024] Further, such as Figure 3 As shown, T-shaped sliders 2031 are provided at both ends of the opposite side of the cutter 203 and the sleeve 201, and a slide groove 2012 is opened on the sleeve 201 relative to the position of the T-shaped slider 2031. The T-shaped slider 2031 is inserted into the slide groove 2012, and the two side surfaces of the top of the T-shaped slider 2031 are connected to the inner walls of the two sides of the slide groove 2012, and the two end surfaces of the bottom of the T-shaped slider 2031 are connected to the inner wall of the sleeve 201. The cutter 203 and the sleeve 201 are limited by the T-shaped slider 2031 and the slide groove 2012 to prevent the cutter 203 from falling off or shaking left and right.
[0025] In further, Figure 1 , Figure 2As shown, a mounting cylinder 204 is provided on the top of the sleeve 201, and the inner cavity of the mounting cylinder 204 is communicated with the inner cavity of the sleeve 201. A rectangular guide rod 205 is passed through the sleeve 201, and the bottom end of the guide rod 205 extends to the inner cavity of the sleeve 201 and is fixedly connected with a pressing block 206. The lower surface of the pressing block 206 is connected to the surface of the food packaging bag roll 1, and a spring 207 is sleeved on the bottom surface of the guide rod 205. One end of the spring 207 is fixedly connected to the top surface of the pressing block 206, and the other end of the spring 207 is fixed to the mounting cylinder 20 The top of the guide rod 205 extends to the outside of the installation cylinder 204 and is fixedly connected with a pull rod 208. When installing the food packaging bag roll 1, the pull rod 208 is pulled upward, and the pull rod 208 drives the guide rod 205 and the pressing block 206 to move upward, and compresses the spring 207 at the same time, and then the food packaging bag roll 1 is sleeved on the rotating shaft 202, and the pull rod 208 is released. The spring 207 is reset and drives the pressing block 206 to press on the food packaging bag roll 1 to prevent the food packaging bag roll 1 from falling off the rotating shaft 202.
[0026] Furthermore, if Figure 1 , Figure 2 As shown, the pressing block 206 is in an arc shape, and smooth arc surfaces 2061 are provided at both ends of the pressing block 206.

At this time, the arc surfaces 2061 at both ends of the pressing block 206 are in contact with the surface of the food packaging bag roll 1. When the food packaging bag on the food packaging bag roll 1 is pulled outward, the arc surfaces 2061 at both ends of the pressing block 206 can prevent the surface of the food packaging bag from being scratched.
[0027] It is worth noting that if Figure 2 As shown, a rectangular sliding hole 2041 is opened at the top of the installation cylinder 204, the top of the guide rod 205 is penetrated through the sliding hole 2041, and the side surface of the guide rod 205 is connected to the inner wall of the sliding hole 2041 to prevent the guide rod 205 from rotating in the sliding hole 2041.
[0028] Working principle: This embodiment provides a wear-resistant food packaging bag. When in use, the cutter 203 is pushed downward by the toggle plate 209 to drive the T-shaped slider 2031 to slide in the slide groove 2012, so that the blade of the cutter 203 is in contact with the end of the food packaging bag on the food packaging bag roll 1. The toggle plate 209 is pressed with a finger to tear the food packaging bag upward along the blade of the cutter 203, so that the food packaging bag on the food packaging bag roll 1 can be torn off; when installing the food packaging bag roll 1, the pull rod 208 is pulled upward, and the pull rod 208 drives the guide rod 205 to move upward along the slide hole 2041, drives the pressing block 206 to move upward, and compresses the spring 207 at the same time, and then the food packaging bag roll 1 is put on the rotating shaft 202, and the pull rod 208 is released. The spring 207 is reset to drive the arc surfaces 2061 at both ends of the pressing block 206 to press on the food packaging bag roll 1 to prevent the food packaging bag roll 1 from falling off the rotating shaft 202.
