Description

Technical Field

[0001] This utility model relates to the field of thermal paper technology, specifically a laminated thermal label paper. Background Technology

[0002] Thermal label paper is a special type of paper treated with a highly heat-sensitive coating. It develops text or images through a thermochemical reaction and is widely used in logistics, supermarkets, medical fields, and other areas. The core structure of thermal label paper usually consists of three layers: paper base (bottom support), thermal coating (containing colorless dyes and developers), and protective layer (delaying coating degradation). Its development principle is that when the print head is heated, the chemical substances in the coating react to generate color, without the need for ink or toner.

[0003] The aforementioned technologies have certain shortcomings in their use: thermal label paper is greatly affected by the external environment after printing, such as being susceptible to scratches and friction, which may cause the content on the surface to be lost. Current thermal label paper offers relatively low surface protection during use.

[0004] Therefore, this utility model provides a laminated thermal label paper to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a laminated thermal label paper that solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a laminated thermal label paper, including a base, a feeding component for winding and conveying the thermal label paper body is installed on the top wall of the base, an L-shaped frame is fixedly installed on the top wall of the base, a coating component for laminating the surface of the thermal label paper body is installed on the top wall of the L-shaped frame, a leveling component for leveling the surface of the thermal label paper body is installed on the side wall of the coating component, and a drying component for drying the surface of the laminated thermal label paper body is fixedly installed at the rear of the top wall of the L-shaped frame.

[0007] The coating assembly includes a lifting push rod fixedly installed on the top wall of an L-shaped frame. The movable end of the lifting push rod slides through the L-shaped frame and is fixedly installed on a mounting base. A coating nozzle for coating the surface of the thermal label paper is installed on the bottom wall of the mounting base. A scraper is installed on the bottom wall of the mounting base and on one side of the coating nozzle. A U-shaped seat is fixedly installed on the bottom wall of the mounting base and on one side of the scraper. A rotating roller is installed on the inner wall of the U-shaped seat to perform roll pressing treatment on the surface of the thermal label paper after coating with polyester film. A processing table is fixedly installed on the top wall of the base.

[0008] The above technical solution enables the coating component to uniformly coat the surface of the thermal label paper with a polyester film of a certain thickness, thereby improving the protection of the contents of the thermal label paper and extending the service life of the entire label paper.

[0009] Furthermore, the bottom wall of the mounting base is fixedly connected to the drying component, and a positioning rod is fixedly installed on the rear part of the top wall of the mounting base. The top of the positioning rod slides through the L-shaped frame and extends to the outside. The left side wall of the mounting base is fixedly connected to the leveling component.

[0010] The positioning rod, as described above, is mainly used to limit the movement trajectory of the mounting base and prevent path deviation.

[0011] Furthermore, the drying assembly includes a fan fixedly installed on the rear of the top wall of the L-shaped frame. The air inlet of the fan is connected to the outside through an air inlet pipe, and the air outlet of the fan is connected to a movable pipe. An exhaust ring pipe is installed on the bottom wall of the mounting base through several connecting seats. The air inlet end of the exhaust ring pipe is connected to the movable pipe, and several air outlets are evenly installed on the bottom wall of the exhaust ring pipe.

[0012] The above technical solution involves using a fan to deliver airflow into the active pipe and exhaust ring pipe, and then discharging it from the outlet end to dry the coated thermal label paper.

[0013] Furthermore, the leveling component includes a support platform fixedly installed on both sides of the processing table. A limit frame is fixedly installed on the left side wall of the mounting base via a U-shaped frame. Limit grooves are opened on both the front and rear walls of the limit frame. Several abutment springs are evenly fixedly installed on the top wall inside the limit frame. The bottom of the several abutment springs are all fixedly installed with the same slide.

[0014] The limiting frame, as described above, is mainly used to accommodate the abutment spring and the slide block.

[0015] Furthermore, limit blocks are fixedly installed on the front and rear walls of the slide and at the corresponding limit groove positions. The outer walls of the limit blocks are slidably connected to the inner walls of the corresponding limit grooves. A U-shaped platform is fixedly installed on the bottom wall of the slide, and a flattening roller is rotatably installed on the inner wall of the U-shaped platform.

[0016] The above technical solution uses a leveling roller to level the surface of the thermal label paper, preventing wrinkles from affecting the coating effect. When the leveling roller applies force to the thermal label paper, it will drive the U-shaped stage and slide into the limiting frame to compress the abutment spring, and under its elastic action, push the leveling roller to apply force to the thermal label paper.

[0017] Furthermore, the feeding assembly includes support frames fixedly installed on the left and right sides of the top wall of the base. A feeding roller is rotatably installed on the inner wall of the support frame on the left side, and a take-up roller is rotatably installed on the inner wall of the support frame on the right side. A drive motor is fixedly installed on the front wall of the support frame on the right side, and the power shaft of the drive motor passes through the corresponding support frame and is fixedly connected to the take-up roller shaft through a bearing.

[0018] The above technical solution provides a support frame that is mainly used to accommodate the feeding roller and the winding roller, and drives the winding roller to wind up the thermal label paper via a drive motor.

[0019] Furthermore, two side plates are fixedly installed on the inner walls of both support frames, and the same guide roller is rotatably installed on the inner walls of the two side plates on the same side.

[0020] Through the above technical solution, the main function of the guide roller is to guide the direction of the thermal label paper. Beneficial effects

[0021] This invention provides a laminated thermal label paper. Compared with the prior art, it has the following advantages:

[0022] (1) The coated thermal label paper, through the setting of the coating component and the drying component, uniformly coats the surface of the label paper with a certain thickness of polyester film during the production and processing of the thermal label paper, and air-dries the coated label paper, so that the label paper has good scratch resistance and good protection of its surface when used, preventing the problem of content loss, delaying the erosion of the label paper by ultraviolet rays and moisture in the external environment, and extending the service life.

[0023] (2) The thermal label paper, through the setting of the feeding component and the flattening component, can be slowly rolled up in conjunction with the use of the coating component when the thermal label paper is coated, and the flattening component can flatten the roll of label paper before coating to prevent wrinkles from affecting the coating effect.

[0041] Please see Figures 1-7This embodiment provides a technical solution based on embodiment one: the leveling component 7 includes a support platform 79 fixedly installed on both sides of the processing table 68, a limit frame 71 fixedly installed on the left side wall of the mounting base 63 through a U-shaped frame 78, limit grooves 72 are opened on the front and rear walls of the limit frame 71, a plurality of abutment springs 73 are evenly fixedly installed on the inner top wall of the limit frame 71, the same slide block 74 is fixedly installed at the bottom end of the plurality of abutment springs 73, limit blocks 75 are fixedly installed on the front and rear walls of the slide block 74 at positions corresponding to the limit grooves 72, the outer walls of the limit blocks 75 are slidably connected to the inner walls of the corresponding limit grooves 72, a U-shaped platform 76 is fixedly installed on the bottom wall of the slide block 74, and a leveling roller 77 is rotatably installed on the inner wall of the U-shaped platform 76;

[0042] In this embodiment of the utility model, the purpose of this setting is that the flattening component 7 is mainly to flatten the thermal label paper 3 before coating, so as to prevent the roll of thermal label paper 3 from having wrinkles that would affect the full coverage of subsequent coating.

[0043] Example 4:

[0044] Please see Figures 1-7 This embodiment provides a technical solution based on embodiment one: the feeding assembly 2 includes support frames 21 fixedly installed on the left and right sides of the top wall of the base 1. A feeding roller 22 is rotatably installed on the inner wall of the support frame 21 on the left side, and a winding roller 26 is rotatably installed on the inner wall of the support frame 21 on the right side. A drive motor 25 is fixedly installed on the front wall of the support frame 21 on the right side. The power shaft of the drive motor 25 passes through the corresponding support frame 21 through a bearing and is fixedly connected to the roller shaft of the winding roller 26. Two side plates 23 are fixedly installed on the inner side walls of the two support frames 21. The same guide roller 24 is rotatably installed on the inner wall of the two side plates 23 on the same side.

[0045] In this embodiment of the utility model, the purpose of this arrangement is that the feeding component 2 is mainly to continuously feed the thermal label paper 3 through the feeding roller 22 and control the winding roller 26 to perform real-time winding through the drive motor 25, thereby completing the coating of the thermal label paper 3 with polyester film.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0047] The working principle of this device is as follows: Before operation, the drive motor 25, fan 51, and lifting push rod 61 are electrically connected through an external power supply and controller. The thermal label paper 3 to be processed is first guided out from the surface of the feeding roller 22, passes through the bottom of the left guide roller 24, and is then connected to the winding roller 26 through the support platform 79, processing platform 68, and right guide roller 24.

[0048] The lifting push rod 61 is activated to push the mounting base 63 and drive the positioning rod 62 to descend. The positioning rod 62 limits the movement trajectory of the mounting base 63 to prevent path deviation. As the mounting base 63 continues to descend, it will drive the various components installed at the bottom to move downward synchronously.

[0049] Mounting base 63 drives the retractable frame 78 and limiting frame 71 to descend, causing the slide 74, U-shaped platform 76 and leveling roller 77 installed inside the limiting frame 71 to descend and approach the thermal label paper body 3. As the limiting frame 71 continues to descend, the leveling roller 77 applies a certain pressure to the surface of the thermal label paper body 3. The thermal label paper body 3 contacts the top wall of the support platform 79 and pushes the slide 74 to compress the abutment spring 73, causing the limiting block 75 on the slide 74 to slide along the inner wall of the limiting groove 72, preventing the slide 74 and U-shaped platform 76 from deviating from their paths. The leveling roller 77 flattens the surface of the thermal label paper body 3, ensuring comprehensive coverage when coating with polyester film later.

[0050] Mounting base 63 drives coating nozzle 67, scraper 66, U-shaped seat 64 and rotating roller 65 to descend. Polyester film material is discharged from coating nozzle 67 onto the surface of thermal label paper 3. Drive motor 25 drives take-up roller 26 to rotate and synchronously take up thermal label paper 3. Scraper 66 gradually scrapes the polyester film material to evenly cover the surface of thermal label paper 3. At the same time, rotating roller 65 rolls the thermal label paper 3 after the polyester film material is scraped to improve the contact adhesion between polyester film and thermal label paper 3 and improve the coating quality.

[0051] The blower 51 is started to deliver airflow into the movable pipe 52, which is discharged from the outlet end 54 through the exhaust ring pipe 53. The thermal label paper 3, which has been coated on the surface of the processing table 68, is air-dried. After the processing is completed, the thermal label paper 3 is wound up by the winding roller 26.
