Description

Technical Field

[0001] This utility model relates to the field of thermal paper production technology, specifically a flattening device for thermal paper production. Background Technology

[0002] A thermal paper flattening device is a piece of equipment used to flatten and level thermal paper during the production process. Its main function is to flatten the thermal paper through a specific mechanical structure to ensure that its surface is smooth and flat, so as to meet the needs of subsequent processing.

[0003] Patent CN222855856U discloses a surface treatment device for thermal label paper production. This utility model aims to provide a surface treatment device for thermal label paper production that can flatten thermal label paper, ensure the coating effect of the thermal coating, and improve the production quality of thermal label paper. A surface treatment device for thermal label paper production includes a mounting frame, a transmission belt, and a surface treatment frame. The transmission belt is wound around the upper side of the mounting frame, and the surface treatment frame is connected to the upper part of the mounting frame. This utility model achieves the effect of flattening the thermal label paper by retracting the telescopic end of the telescopic rod, causing the connecting block to move downwards, and causing the flattening frame to move downwards. This ensures the coating effect of the thermal coating and improves the production quality of the thermal label paper.

[0004] The above-mentioned device has certain shortcomings in use: thermal paper is different from ordinary paper. Its surface is covered with a thin film containing a special dye, which is the thermochromic layer. Since the bottom of the flattening frame is in contact with the surface of the thermal paper, when the thermal label paper passes through the bottom of the flattening frame, the friction generates heat, which may cause the thermochromic layer to change color.

[0005] To address these issues, this invention provides a flattening device for thermal paper production. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a flattening device for thermal paper production, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a flattening device for thermal paper production, including a worktable, a feeding roller installed on the left side of the top wall of the worktable, a receiving roller installed on the right side of the top wall of the worktable, a cleaning component installed on the top wall of the worktable, and a flattening component fixedly installed in the middle of the top wall of the worktable.

[0008] The flattening assembly includes a U-shaped frame fixedly installed on the top wall of the workbench. A lifting push rod is installed on the top wall of the U-shaped frame. The movable end of the lifting push rod slides through the U-shaped frame and is fixedly installed with a lifting frame. A lifting block is fixedly installed at the bottom of the lifting frame. A dynamic flattening roller is rotatably installed between the lifting blocks. Limit grooves are opened on both the front and rear walls of the U-shaped frame. Limit blocks are slidably installed on the inner walls of the two limit grooves. The two limit blocks are fixedly connected to the corresponding lifting blocks. Distance sensors are installed on the bottom walls of the two limit blocks. Sensors are fixedly installed on the inner walls of the two limit grooves. A constant pressure flattening roller is rotatably installed on the inner wall of the U-shaped frame and at the bottom of the dynamic flattening roller.

[0009] Through the above technical solution, the setting of the flattening component can adjust the distance between the dynamic flattening roller and the fixed flattening roller according to the thermal paper of different thicknesses, and the distance can be monitored in real time by the distance measuring sensor and the sensor.

[0010] Furthermore, the outer walls of both sensors are electrically connected to the corresponding ranging sensors. Connecting rods are fixedly installed on the front and rear parts of the top wall of the lifting frame. Lifting frames are fixedly installed on both sides of the bottom end of the two connecting rods. Positioning grooves are opened on the front and rear walls of the two lifting frames. Several abutting springs are evenly fixedly installed on the top walls of the two lifting frames. The bottom ends of the several abutting springs on the same side are fixedly installed with the same slide block. The outer walls of the two slide blocks are slidably connected to the inner walls of the corresponding lifting frames.

[0011] Through the above technical solution, when the lifting frame moves up and down, it will drive the connecting rod and the lifting frame to move up and down, thereby driving the slide to move synchronously.

[0012] Furthermore, positioning blocks are fixedly installed on the outer walls of both slides at the positions corresponding to the positioning grooves, and the outer walls of several positioning blocks are slidably connected to the inner walls of the corresponding positioning grooves. Processing rollers are installed on the bottom walls of both slides.

[0013] With the above technical solution, when the slide block slides in the inner wall of the lifting frame, it will drive the positioning block to slide in the inner wall of the positioning groove to prevent positional deviation. At the same time, the processing roller performs roll pressing pretreatment on the thermal paper.

[0014] Furthermore, pressure plates are fixedly installed on the outer walls of the U-shaped frame, and guide rollers are rotatably installed on the side walls of both pressure plates.

[0015] Through the above technical solution, the main function of the guide roller is to guide the thermal paper smoothly through the upper part of the pressure plate and prevent friction with the pressure plate.

[0016] Furthermore, the cleaning assembly includes two mounting brackets fixedly installed on both sides of the top wall of the workbench. The inner walls of both mounting brackets are equipped with conveying pipes, and the bottom of each conveying pipe is connected to several cleaning pipes.

[0017] The above technical solution allows the airflow received by the conveying pipe to be blown out through the cleaning pipe to clean the surface of the thermal paper.

[0018] Furthermore, the rear ends of the two conveying pipes are connected to the corresponding mounting brackets through leak-proof rubber sleeves, and the bottom ends of the two connecting pipes are connected to the same connecting pipe. A fan is fixedly installed on the rear wall of the workbench, and the air outlet of the fan is connected to an air outlet pipe. The top end of the air outlet pipe is connected to the connecting pipe.

[0019] Through the above technical solution, the fan delivers airflow to the connecting pipe and the connecting pipe through the air outlet pipe, and then enters the cleaning pipe for discharge through the conveying pipe.

[0020] Furthermore, the air inlet of the fan is connected to the outside through an air inlet pipe, and a main controller is installed on the front wall of the workbench.

[0021] Through the above technical solution, the main controller can control the electrical control components of the entire device to operate.

[0038] Example 2:

[0039] Please see Figures 1-5 This embodiment provides a technical solution based on embodiment one: the cleaning component 5 includes two mounting brackets 55 fixedly installed on both sides of the top wall of the workbench 1. The inner walls of the two mounting brackets 55 are equipped with conveying pipes 56. The bottom of the two conveying pipes 56 is connected to several cleaning pipes 57. The rear ends of the two conveying pipes 56 pass through the corresponding mounting brackets 55 through the anti-leakage rubber sleeve and are connected to the connecting pipes 54. The bottom ends of the two connecting pipes 54 are connected to the same connecting pipe 53. A fan 51 is fixedly installed on the rear wall of the workbench 1.

[0040] In this embodiment of the utility model, the purpose of this arrangement is that the cleaning component 5 can improve the cleanliness of the thermal paper surface by blowing airflow when the thermal paper is rolled, so as to prevent impurities and dust attached to the surface from affecting the subsequent printing effect.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] The working principle of this device is as follows: During operation, the fan 51, lifting push rod 61, distance sensor 66, and sensor 67 are electrically connected through an external power supply and a main controller 2. The thermal paper on the feeding roller 3 is extended outward through the mounting frame 55, processing roller 616, guide roller 618, and dynamic pressure flat roller 69 before connecting to the receiving roller 4. The distance between the dynamic pressure flat roller 69 and the constant pressure flat roller 619 is adjusted according to the thickness of the thermal paper. The lifting push rod 61 pushes the lifting frame 63 to move downward within the U-shaped frame 62. When the lifting frame 63 moves downward, the lifting block 68 drives the limiting block 65 to slide downward in the inner wall of the limiting groove 64. The distance sensor 66 senses the distance between itself and the sensor 67, and the distance between the dynamic pressure flat roller 69 and the constant pressure flat roller 619 can be measured to match the thickness of the thermal paper.

[0043] When the lifting frame 63 moves downward, it will drive the connecting rod 610 and the lifting frame 611 to move downward, causing the lifting frame 611 to drive the slide 613 and the processing roller 616 to gradually descend. The processing roller 616 comes into contact with the thermal paper after passing through the surface of the pressure plate 617. As the lifting frame 611 continues to descend, the slide 613 slides in the inner wall of the lifting frame 611 and drives the positioning block 615 to slide in the inner wall of the positioning groove 612. At the same time, the slide 613 compresses the abutment spring 614, and under the elastic action of the abutment spring 614, it pushes the processing roller 616 to apply a certain pressure to the surface of the thermal paper.

[0044] The fan 51 is started to draw air from the outside, which is then conveyed through the air outlet pipe 52 to the connecting pipe 53, and then through the connecting pipe 54 into the conveying pipe 56 and discharged from the cleaning pipe 57 to clean the surface of the thermal paper that passes through the inner wall of the mounting frame 55.

[0045] When the take-up roller 4 rotates, it winds up the thermal paper and blows the thermal paper surface through the bottom of the cleaning pipe 57 to clean any impurities that may be attached to the paper surface, thereby improving the cleanliness of the thermal paper surface and preventing dust and impurities from affecting the finished product during later printing.

[0046] After the thermal paper is guided and conveyed by the guide roller 618, it is gradually processed by the two side processing rollers 616 and the dynamic pressing roller 69. This process flattens the wrinkles on the surface of the thermal paper, thus completing the flattening process during the production of thermal paper. The overall rolling method can reduce the friction with the thermal paper and prevent the thermal color-changing layer from discoloring or leaving marks.
