Description

Technical Field

[0001] This utility model relates to the field of label printing technology, specifically to a material feeding mechanism for printing ultra-high frequency electronic labels. Background Technology

[0002] UHF RFID tags are widely used in many fields due to their advantages such as long-distance identification, large-capacity data storage, and rapid batch reading. In the logistics industry, UHF RFID tags enable real-time tracking and inventory of goods. In retail, they facilitate rapid settlement and anti-theft management. With the continuous development of the Internet of Things and smart scenarios, the market demand for UHF RFID tags continues to grow, and the requirements for their production efficiency and quality are also increasing. Label printing, as a key link in the production of UHF RFID tags, directly affects the readability, durability, and information accuracy of the tags. The feeding mechanism, as a basic component in the printing process, undertakes the important task of stably conveying the label substrate and ensuring printing accuracy.

[0003] In the existing technology, an unwinding device is used to release the label substrate roll, and a tension control system adjusts the tension to prevent the material from loosening or becoming overly tight. A guide roller group guides the material path. However, the lack of a guiding mechanism makes it easy for the label and roller to curl or tear during feeding due to friction. Furthermore, it is not convenient to adjust the guiding mechanism according to different situations, making it difficult to adapt to the stacking of label paper of different thicknesses, resulting in poor practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a feeding mechanism for printing ultra-high frequency electronic labels. It can effectively solve the problems in the prior art, which does not have a guide mechanism, which easily leads to edge curling or tearing of the label and roller due to friction. Furthermore, it is not convenient to adjust the guide mechanism according to different situations, thus making it difficult to adapt to the stacking of label paper of different thicknesses, resulting in poor practicality.

[0005] The technical solution adopted by this utility model is: a feeding mechanism for printing ultra-high frequency electronic tags, including a housing and a feeding mechanism. A printer body is fixedly installed at one end of the housing near the feeding mechanism, a feeding mechanism is fixedly installed at one end of the printer body, a guiding mechanism is fixedly installed at the end of the printer body away from the feeding mechanism, and a limit mechanism is provided inside the housing.

[0006] The feeding mechanism includes a transmission roller, a fixed frame, and a fixed rod. The fixed rod is fixedly installed to the printer body, and a feeding tray is rotatably installed on the outer edge of the transmission roller.

[0007] The guiding mechanism includes a bracket and a support base, both of which are fixedly installed to the housing. A guide plate is fixedly installed at the end of the bracket away from the support base.

[0008] The limiting mechanism includes a first limiting plate, a second limiting plate, and a base plate. A hinge is provided at the end of the first limiting plate near the housing, and a retainer is fixedly installed at the end of the second limiting plate near the housing.

[0009] Preferably, a limiter and a mounting rod are fixedly installed at the end of the drive roller away from the feed pan, and the end of the drive roller closer to the feed pan is engaged with a limit pan.

[0010] By using the above technical solution, the limiter fixed to the end of the transmission roller can block the axial displacement of the feeding disc, prevent the label paper roll from shifting when rotating, and avoid the label paper from being skewed due to the shaking of the disc.

[0011] Preferably, the guide plate has an arc-shaped design at both ends, and a material conveying channel is provided through one end of the printer body near the feeding mechanism. The height of the guide plate is lower than the height of the material conveying channel.

[0012] Through the above technical solution, the arc-shaped design at both ends of the guide plate can reduce friction damage to the edge of the label paper, avoid curling or tearing during feeding, and its height is lower than that of the feeding channel, so that the label paper forms a natural downward arc when transitioning from the guide plate to the channel, using gravity to assist alignment, avoiding easy jamming during feeding, thereby improving smoothness.

[0013] Preferably, a mounting bracket is fixedly installed along the inner edge of the housing, a mounting column is rotatably installed along the inner edge of the mounting bracket, and a feeding roller is fixedly installed along the outer edge of the mounting column, with the feeding roller located obliquely below the guiding mechanism.

[0014] With the above technical solution, the feeding roller is installed obliquely below the guiding mechanism via the mounting column. It can cooperate with the guiding plate to form an "S" shaped feeding path, which can not only guide the material, but also prevent breakage due to excessive tension, and prevent accumulation due to insufficient tension.

[0015] Preferably, a second hinge is provided at one end of the base plate near the housing, and a baffle is fixedly installed at the end of the base plate away from the first limiting plate. The end of the second hinge away from the base plate is fixedly installed to the housing.

[0016] Through the above technical solution, the base plate can be flipped by hinge two to the machine housing, thereby selecting either limit plate one or limit plate two for guidance, adapting to the stacking of label paper of different thicknesses. At the same time, the baffle is fixed to the end of the base plate, which can limit the lateral movement range of the label paper.

[0017] Preferably, the first limiting plate is fixedly installed to the housing via a first hinge, and the second limiting plate is fixedly installed to the housing via a fastener.

[0018] Through the above technical solution, the limiting plate one can be rotated and adjusted by the hinge one, forming an adjustable clamping structure with the limiting plate two, which can adapt to label paper of different widths, and the fixing device can use bolts to fix the limiting plate two to the machine housing.

[0019] Preferably, there are multiple identical hinges and fasteners, and the multiple hinges and fasteners are distributed at equal intervals.

[0020] Through the above technical solution, multiple sets of equally spaced hinges and fasteners can enhance the installation rigidity of the limiting plate, avoid plate deformation caused by single-point force, and make the pressure distribution of the limiting plate on the label paper uniform.

[0021] Compared with the prior art, this utility model provides a feeding mechanism for printing ultra-high frequency electronic tags, which has the following advantages:

[0022] 1. The feeding mechanism for UHF electronic label printing has an arc-shaped design at both ends of the guide plate, which can reduce friction damage to the edge of the label paper and avoid curling or tearing during feeding. In addition, its height is lower than the feeding channel, so that the label paper forms a natural downward arc when transitioning from the guide plate to the channel. Gravity assists in alignment and avoids jamming during feeding, thereby improving smoothness.

[0023] 2. The feeding mechanism for UHF electronic tag printing is adjustable by means of a first limiting plate and a second limiting plate, forming an adjustable clamping structure. It can accommodate label paper of different widths and can be guided by either the first or the second limiting plate to accommodate the stacking of label paper of different thicknesses. The fixing device can use bolts to fix the second limiting plate to the machine housing for quick installation and improve the versatility of use. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1: As Figure 1-10 As shown, the present invention provides a material feeding mechanism for printing ultra-high frequency electronic tags, including a housing 1 and a feeding mechanism 2. A printer body 3 is fixedly installed at one end of the housing 1 near the feeding mechanism 2, the feeding mechanism 2 is fixedly installed at one end of the printer body 3, and a guide mechanism 5 is fixedly installed at the other end of the printer body 3 away from the feeding mechanism 2. A limit mechanism 9 is provided inside the housing 1.

[0037] The feeding mechanism 2 includes a transmission roller 201, a fixed frame 202 and a fixed rod 203. The fixed rod 203 is fixedly installed with the printer body 3. A feeding tray 206 is rotatably installed on the outer edge of the transmission roller 201.

[0038] The guiding mechanism 5 includes a bracket 501 and a support base 502. Both the bracket 501 and the support base 502 are fixedly installed to the housing 1. A guide plate 503 is fixedly installed at the end of the bracket 501 away from the support base 502.

[0039] The limiting mechanism 9 includes a first limiting plate 901, a second limiting plate 903 and a base plate 905. The first limiting plate 901 is provided with a first hinge 902 at one end near the housing 1, and the second limiting plate 903 is fixedly installed with a retainer 904 at one end near the housing 1.

[0040] Specifically, a limiter 204 and a mounting rod 205 are fixedly installed at the end of the drive roller 201 away from the feed tray 206, and a limiter 207 is engaged at the end of the drive roller 201 closer to it. The advantage is that by fixing the limiter 204 to the end of the drive roller 201, the axial displacement of the feed tray 206 can be blocked, preventing the label paper roll from shifting when rotating, and avoiding the label paper from being skewed due to the shaking of the tray.

[0041] Specifically, the guide plate 503 has an arc-shaped design at both ends. The printer body 3 has a feeding channel 4 through one end near the feeding mechanism 2. The height of the guide plate 503 is lower than the height of the feeding channel 4. The advantage is that the arc-shaped design at both ends of the guide plate 503 can reduce friction damage to the edge of the label paper, avoid curling or tearing during feeding, and its height is lower than the feeding channel 4, so that the label paper forms a natural downward arc when transitioning from the guide plate 503 to the channel, using gravity to assist alignment, avoiding jamming during feeding, thereby improving smoothness.

[0042] Specifically, a mounting bracket 6 is fixedly installed on the inner edge of the housing 1, and a mounting column 7 is rotatably installed on the inner edge of the mounting bracket 6. A feeding roller 8 is fixedly installed on the outer edge of the mounting column 7. The feeding roller 8 is located obliquely below the guide mechanism 5. The advantage is that by installing the feeding roller 8 on the obliquely below the guide mechanism 5 through the mounting column 7, it can cooperate with the guide plate 503 to form an "S" shaped feeding path, which can not only guide it, but also prevent breakage due to excessive tension, and also prevent accumulation due to insufficient tension.

[0043] Example 2: Figure 2-10 As shown, this is an improvement on the previous embodiment.

[0044] Specifically, a second hinge 906 is provided at one end of the base plate 905 near the housing 1, and a baffle 907 is fixedly installed at the end of the base plate 905 away from the first limiting plate 901. The end of the second hinge 906 away from the base plate 905 is fixedly installed to the housing 1. The advantage is that the base plate 905 can be flipped by hinge 906 to the housing 1, so as to select the first limiting plate 901 or the second limiting plate 903 for guidance, which can adapt to the stacking of label paper of different thicknesses. At the same time, the baffle 907 is fixed at the end of the base plate 905, which can limit the lateral movement range of the label paper.

[0045] Specifically, the first limiting plate 901 is fixedly installed to the housing 1 via the first hinge 902, and the second limiting plate 903 is fixedly installed to the housing 1 via the fixing device 904. The advantage is that the first limiting plate 901 can be rotated and adjusted via the first hinge 902, forming an adjustable clamping structure with the second limiting plate 903, which can adapt to label paper of different widths. Furthermore, the fixing device 904 can use bolts to fix the second limiting plate 903 to the housing 1.

[0046] Specifically, multiple hinges 902 and fasteners 904 are provided, and the multiple hinges 902 and fasteners 904 are distributed at equal intervals. The advantage is that multiple sets of equally spaced hinges 902 and fasteners 904 can enhance the installation rigidity of the limiting plate 901, avoid plate deformation caused by single-point force, and make the pressure of the limiting plate 901 on the label paper evenly distributed.

[0047] Working Principle: During use, the limiter 204 is fixed to the end of the transmission roller 201, which can block the axial displacement of the feeding disc 206 and prevent the label roll from shifting during rotation. This avoids the label paper from being skewed due to disc shaking. The arc-shaped design at both ends of the guide plate 503 can reduce friction damage to the edges of the label paper, preventing curling or tearing during feeding. Furthermore, its height is lower than the feeding channel 4, allowing the label paper to form a natural downward arc when transitioning from the guide plate 503 to the channel. Gravity assists in alignment, preventing jamming during feeding and improving smoothness. The feeding roller 8 is installed diagonally below the guide mechanism 5 via the mounting column 7, and can cooperate with the guide plate 503 to form an "S"-shaped feeding path, which not only guides the paper but also prevents breakage due to excessive tension. To prevent stacking due to insufficient tension, the base plate 905 is hinged to the housing 1 via hinge 2 906 and can be flipped to select either limit plate 1 901 or limit plate 2 903 for guidance, accommodating the stacking of label paper of different thicknesses. At the same time, the baffle 907 is fixed to the end of the base plate 905 to limit the lateral movement range of the label paper. Limit plate 1 901 can be rotated and adjusted via hinge 1 902, forming an adjustable clamping structure with limit plate 2 903 to accommodate label paper of different widths. Furthermore, the retainer 904 can use bolts to fix limit plate 2 903 to the housing 1. Multiple sets of equally spaced hinge 1 902 and retainer 904 can enhance the installation rigidity of limit plate 1 901, avoid plate deformation caused by single-point force, and ensure that the pressure of limit plate 1 901 on the label paper is evenly distributed.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
