DETAILED DESCRIPTION

[0023] The following is a combination of the appended examples of the present invention Figure 1-6 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] As shown in the figure, a new type of packaging bag includes a bag body 1, and a marking component 2 is provided at the side end of the bag body 1. The marking component 2 includes a shell 21, a paper roll 22, a marking paper roll 23 and a cover plate 24. The shell 21 is made of transparent plastic material and a paper roll cavity 211 and a display cavity 212 with open side ends and interconnected are formed in the shell 21. The lower end of the display cavity 212 is open, the paper roll 22 is rotatably arranged in the paper roll cavity 211, the marking paper roll 23 is sleeved on the paper roll 22 and located in the paper roll cavity 211, and the marking paper led out from the marking paper roll 23 is inserted into the display cavity 212, and a positioning hole 241 matching the end of the paper roll 22 is opened on the cover plate 24. The cover plate 24 is fixedly connected to the side end of the shell 21 to close the openings of the side ends of the paper roll cavity 211 and the display cavity 212 and allow the end of the paper roll 22 to pass through the positioning hole 241.

[0025] Specifically, the shell 21 is fixedly connected to the structure of the bag body 1: a first clamping plate 216 is formed on the side end of the shell 21 facing the bag body 1, and a support plate 217 is formed at each end of the first clamping plate 216. The two support plates 217 are rotatably connected by an eccentric shaft with a tensioning shaft 26 that is kept in contact with the first clamping plate 216, so that the tensioning shaft 26 will expand with the first clamping plate 216 during the rotation process and press against the first clamping plate 216 to generate a large friction force. The friction force keeps the tensioning shaft 26 and the first clamping plate 216 relatively stable. A second clamping plate 261 is formed on the tensioning shaft 26. When the tensioning shaft 26 is tightened by the second clamping plate, the first clamping plate 216 and the second clamping plate 261 cooperate to clamp the side end of the bag body 1 to achieve a fixed connection between the shell 21 and the bag body 1.

[0026] In the above structure, the marking component 2 is fixedly connected to the bag body 1 through the shell 21 and the side end of the bag bottom, and is located at the side end of the bag body 1. When an item is put into the bag body 1 and the content needs to be marked, the paper roll 22 is rotated to pass through the end of the positioning hole 241. The paper roll 22 drives the marking paper roll 23 mounted thereon to rotate, so that the marking paper on the marking paper roll 23 passes through the display cavity 212 and passes through the lower end opening of the display cavity 212. At this time, the marking paper is pulled out of the display cavity 212 to the length required for writing the marking content. After writing the marking content on the marking paper, the paper roll 22 is rotated to drive the marking paper roll 23 to rotate in the direction, and the marking paper that has passed through the display cavity 212 is retracted and kept in the display cavity 212. The marking content on the marking paper in the display cavity 212 can be observed through the transparent plastic shell 21, so that the content of the bag body 1 can be easily distinguished, meeting the use requirements of multiple bags 1 carrying different contents and stacking them. After the content in the bag body 1 is replaced, the marking paper with the marking content written on it can be passed out of the display cavity 212 in the same way as above. The cavity 212 is opened and torn off, and the marking paper is pulled out to the required length, and the marking content of the replaced contents can be written on the marking paper, thereby realizing the marking of the replaced contents, which is convenient for the reuse of the packaging bag when transferring different contents. The marking component 2 is fixedly connected to the side end of the bag body 1. When the bag bodies 1 are stacked, the adjacent bag bodies 1 are not easy to block the marking component 2, and it is convenient to observe the marking content on the marking component 2 to distinguish the contents in the bag body 1. In addition, by moving the second clamping plate 261 away from the first clamping plate 216 The expansion shaft 26 is driven to rotate away from the position tightened with the first clamp 216 by swinging, so that the first clamp 216 and the second clamp 261 can release the clamping of the side end of the bag body 1, so that the shell 21 and the bag body 1 can be easily connected or separated, thereby conveniently adjusting the position of the marking component 2 on the side end of the bag body 1. When multiple bag bodies 1 are stacked, the marking components 2 on adjacent bag bodies 1 are staggered to avoid obstruction of the marking content on the marking component 2, making it convenient to observe the marking content to distinguish the contents of the bag body 1.

[0027] In addition, a spring cavity 242 is formed on the cover plate 24, and the positioning hole 241 is opened on the bottom wall of the spring cavity 242. A brake spring 25 is provided in the spring cavity 242 to press against the paper reel 22. The friction force generated by the brake spring 25 pressing against the paper reel 22 has a damping effect on the rotation of the paper reel 22, ensuring that the paper reel 22 remains stable when not subject to external force, thereby ensuring that the marking paper with the marking content is stably maintained in the display cavity 212, which is convenient for observation to distinguish the contents of the bag body 1.

[0028] In addition, a knob is inserted into the end of the paper roll 22 passing through the positioning hole 241, and the knob facilitates the operation of rotating the paper roll 22.

[0029] In addition, a connection portion 243 is formed on the edge of the cover 24 surrounding the outer wall of the shell 21, and a plurality of snapping protrusions 244 are formed on the inner wall of the connection portion 243. The shell 21 is provided with a plurality of snapping grooves 213 that match and correspond one to one with the snapping protrusions 244. The snapping protrusions 244 are snapped into the snapping grooves 213 to achieve a fixed connection between the cover 24 and the shell 21. The cover 24 is fixedly connected to the shell 21 through the cooperation of the snapping protrusions 244 and the snapping grooves 213, so that the cover 24 and the shell 21 can be disassembled. When the marking paper roll 23 is consumed and needs to be replaced, the cover 24 can be removed and the marking paper roll 23 can be replaced, so that the durability of the bag body 1 is improved when it is reused.

[0030] In addition, a paper picking slot 214 communicating with the display cavity 212 is provided at the lower end of the shell 21 , and the marking paper held in the display cavity 212 can be pulled more conveniently through the paper picking slot 214 to change the written marking content.

[0031] The lower end of the shell 21 is formed with a plurality of paper cutting teeth 215 located on one side of the lower opening of the display cavity 212. When changing the written marking content, the marking paper can be pulled out of the display cavity 212 and the marking paper can be easily cut by making it rest against the paper cutting teeth 215, which facilitates the operation of tearing the marking paper and makes the cut more neat.

[0032] In addition, a limiting protrusion 218 is formed on the support plate 217, and a limiting groove 262 matching the limiting protrusion 218 is formed on the second clamping plate 261. When the first clamping plate 216 and the second clamping plate 261 cooperate to clamp the side end of the bag body 1, the limiting protrusion 218 is inserted into the limiting groove 262. The cooperation between the limiting protrusion 218 and the limiting groove 262 limits the swing of the second clamping plate 261 relative to the support plate 217, so that the second clamping plate 261 is more stably maintained in the position of cooperating with the second clamping plate 261 to clamp the side end of the bag body 1, thereby enhancing the stability of the shell 21 fixedly connected to the bag body 1.

[0033] In addition, a plurality of first clamping teeth 219 and a plurality of second clamping teeth 263 are respectively formed on the opposite surfaces of the first clamping plate 216 and the second clamping plate 261, and the plurality of first clamping teeth 219 and the plurality of second clamping teeth 263 are staggered. When the first clamping plate 216 and the second clamping plate 261 cooperate to clamp the side end of the bag body 1, the first clamping teeth 219 and the second clamping teeth 263 are stuck in the side end of the bag body 1, thereby increasing the friction between the first clamping plate 216 and the second clamping plate 261 and the bag body 1, thereby enhancing the stability of the shell 21 fixedly connected to the bag body 1.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
