Description

Technical Field

[0001] The utility model relates to, but is not limited to, the field of papermaking technology, and particularly relates to a device for placing RFID on a paper roll. Background Art

[0002] RFID (Radio Frequency Identification), also known as "electronic tag" or "radio frequency tag" or "RFID tag", is a non-contact automatic identification technology. Each RFID has a unique identification code. As a data information carrier and feedback terminal, it is placed inside various products or attached to their surfaces. Driven by an external reading and writing device, through important information such as the RFID identification code, data can be sent, read, and written at any time, enabling various products to be identified and distinguished, thereby enabling real-time monitoring of the status of products during storage, transportation, production, and use, improving production and management efficiency, and saving a large amount of manpower and material resources.

[0003] Chinese Patent Publication No. CN208766704U, published on April 19, 2019, discloses a paper roll RFID placement device, which includes a cylinder for accommodating RFID electronic tags, a cylinder cover matched with the cylinder, and a gasket fixed inside the cylinder cover to prevent the RFID electronic tag from falling off. The cylinder is a hollow cylinder with both ends open, and there is a support unit on the outer wall. The support unit includes four support feet, and the support feet are arc-shaped. The cylinder is firmly clamped in the paper tube through the elasticity of the support feet.

[0004] For example, the existing device for placing RFID on a paper roll combines the RFID label paper with the cylinder, and then combines the cylinder with the paper tube through the support assembly. In the specific implementation process, it is necessary to first screw the cylinder cover off the cylinder, then combine the RFID label paper inside the cylinder cover, and finally position it through the gasket. The overall operation is relatively inconvenient, so it is urgent to propose a corresponding device for placing RFID on a paper roll to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to propose a device for placing RFID on a paper roll in order to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A device for placing RFID on a paper roll includes a cylinder and RFID label paper. A fixed seat is fixedly installed on the outer surface of the vertical end of the cylinder. A support assembly for fixing the cylinder and the paper tube is arranged between the fixed seat and the horizontal end of the cylinder. The RFID label paper is combined in the inner wall of the vertical end of the cylinder through a combination groove. A transparent pressure plate is lapped on the outside of the RFID label paper. An elastic assembly for positioning the pressure plate is arranged between the pressure plate and the vertical end of the cylinder.

[0008] Preferably, the support assembly includes a positioning block, the outer wall of the positioning block is slidably connected to the inner wall of the horizontal end of the cylinder, and a first spring is fixedly installed between the outer wall of the positioning block and the outer wall of the fixed seat.

[0009] Preferably, the elastic assembly includes a connecting piece, the connecting piece is integrally formed with the pressing disc, and a second spring is fixedly installed between the connecting piece and the inner wall of the vertical end of the cylinder. A telescopic part for limiting the offset of the second spring is arranged between the connecting piece and the inner wall of the vertical end of the cylinder.

[0010] Preferably, the telescopic part includes a telescopic rod, both ends of the telescopic rod are fixedly connected to the connecting piece and the inner wall of the cylinder respectively, and the outer wall of the telescopic rod is attached to the inner wall of the second spring.

[0011] Preferably, a limiting ring is integrally formed on the outer wall of the cylinder, and a rough texture is provided on one side of the limiting ring close to the positioning block.

[0012] Preferably, a convex frame is fixedly installed on the front end face of the connecting piece, and the cross section of the convex frame is in an L-shaped structure.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, after the RFID label paper is placed into the combination groove, release the convex frame, and the connecting piece will drive the pressing disc to reset under the action of the second spring. The pressing disc presses on the outside of the RFID label paper to fix the RFID label paper. Then insert the cylinder into the paper tube until the limiting ring is lapped on the outside of the paper tube to realize the RFID placement of the paper roll. Through the design of the limiting ring, it can be avoided that the cylinder is overly combined into the paper tube. And through the design of the pressing disc, connecting piece and spring, while ensuring the flatness of the RFID label paper, the RFID label paper can be directly taken and placed from the outside of the cylinder, thus ensuring the convenience of use of the device for placing RFID into the paper roll.

[0015] 2. In this application, the support assembly is composed of a first spring and a positioning block. When pushing the cylinder to be combined into the paper tube, the positioning block is gradually combined into the cylinder and compresses the first spring. The first spring makes the positioning block closely adhere to the inside of the paper tube through its own elastic force, so as to realize the positioning of the device and the paper tube through friction, thus replacing the design of the traditional elastic support feet. It ensures the stable connection between the device and the paper tube, and compared with the support feet, the spring has greater fatigue resistance, effectively improving the service life of the device for placing RFID into the paper roll.

The RFID label paper 9 is combined with the inner wall of the vertical end of the cylinder 1 through a combination groove 10. A pressure plate 3 provided transparently is lapped on the outside of the RFID label paper 9. An elastic assembly for positioning the pressure plate 3 is provided between the pressure plate 3 and the vertical end of the cylinder 1;

[0025] After the RFID label paper 9 is placed into the combination groove, release the convex frame 5, and the connecting piece 4 will drive the pressure plate 3 to reset under the action of the second spring 11. The pressure plate 3 is pressed against the outside of the RFID label paper 9, thereby realizing the fixation of the RFID label paper 9. Then, insert the cylinder 1 into the paper tube until the limit ring 6 is lapped on the outside of the paper tube, thereby realizing the RFID placement of the paper roll. Through the design of the limit ring 6, the cylinder 1 can be prevented from being overly combined into the paper tube. And through the design of the pressure plate 3, the connecting piece 4 and the second spring 11, while ensuring the flatness of the RFID label paper 9, the RFID label paper 9 can be directly taken and placed from the outside of the cylinder 1, thus ensuring the convenience of using the device for placing a paper roll into an RFID.

[0026] Specifically, Figure 2 and Figure 4 As shown, the support component includes a positioning block 2, the outer wall of the positioning block 2 is slidably connected to the inner wall of the horizontal end of the cylinder 1, and a spring 8 is fixedly installed between the outer wall of the positioning block 2 and the outer wall of the fixing seat 7, the elastic component includes a connecting piece 4, the connecting piece 4 and the pressure plate 3 are integrally formed, and a spring 11 is fixedly installed between the connecting piece 4 and the inner wall of the vertical end of the cylinder 1, and a telescopic part for limiting the displacement of the spring 11 is arranged between the connecting piece 4 and the inner wall of the vertical end of the cylinder 1, the support component consists of a spring 8 and a positioning block 2, when the cylinder 1 is pushed to be combined with the inside of the paper tube, the positioning block 2 is gradually combined with the inside of the cylinder 1 and compresses the spring 8, and the spring 8 makes the positioning block 2 close to the inside of the paper tube through its own elastic force, so as to realize the positioning of the device and the paper tube through friction, thereby replacing the design of the traditional elastic support foot, ensuring the stability of the connection between the device and the paper tube, and the spring has greater fatigue resistance than the support foot, which effectively improves the service life of the device for placing the paper roll into the RFID.

[0027] Specifically, Figure 2 and Figure 3 As shown, the telescopic part includes a telescopic rod 12, and both ends of the telescopic rod 12 are fixedly connected to the connecting piece 4 and the inner wall of the cylinder 1 respectively, and the outer wall of the telescopic rod 12 is in contact with the inner wall of the spring 11. A common telescopic rod 12 is used, which can follow the spring 11 to expand and contract, thereby limiting the deviation of the spring 11. A limiting ring 6 is integrally formed on the outer wall of the cylinder 1 to prevent the cylinder 1 from being excessively coupled to the paper tube, and a rough texture is provided on the side of the limiting ring 6 close to the positioning block 2, thereby further ensuring the stability of the connection between the device and the paper tube.

Through the design of the limiting ring 6, it can prevent the cylinder 1 from being overly combined into the paper tube. And through the design of the pressing disc 3, the connecting piece 4 and the second spring 11, while ensuring the flatness of the RFID label paper 9, the RFID label paper 9 can be directly taken and placed from the outer side of the cylinder 1, thus ensuring the convenience of use of the device for placing RFID into the paper roll. The supporting component consists of the first spring 8 and the positioning block 2. When pushing the cylinder 1 to be combined into the paper tube, the positioning block 2 is gradually combined into the cylinder 1 and compresses the first spring 8. The first spring 8 makes the positioning block 2 closely adhere to the inner part of the paper tube through its own elastic force, so as to achieve the positioning of the device and the paper tube through friction, thus replacing the design of the supporting feet with the traditional elastic setting, ensuring the stable connection between the device and the paper tube. And compared with the supporting feet, the spring has greater fatigue resistance, effectively improving the service life of the device for placing RFID into the paper roll.
