Description

Technical Field

[0001] The utility model relates to a thermal paper provided with a surface thermal color developer layer and a coating doctor blade thereof, belonging to the technical field of thermal paper. Background Art

[0002] Thermal paper is also known as thermal fax paper, thermal recording paper, thermal copying paper, and is also called heat-sensitive copying paper. Thermal paper is a processed paper, and its manufacturing principle is to coat a layer of "thermal coating" (thermal color-changing layer) on high-quality base paper. Although there are more than a dozen chemical drugs used in this color-changing layer, there are at least the following compounds: colorless dyes, and there are a wide variety of these dyes, and the most commonly used are fluorescent compounds; color developers account for less than 20%, and commonly used ones include bisphenol and p-hydroxybenzoic acid; sensitizers account for less than 10%, among which there are compounds such as benzenesulfonamide; fillers account for less than 50%, and commonly used ones include calcium carbonate (fine particles); adhesives account for less than 10%, such as polyvinyl acetate; stabilizers, such as dibenzoyl terephthalate; lubricants, etc. Therefore, the process is difficult and the technical requirements are high.

[0003] The existing waterproof measure for thermal paper is to brush a layer of varnish on the thermal paper, and the varnish plays a certain waterproof role. However, during the process of printing information on the thermal paper, the varnish layer will be melted and damaged due to the heat generated during printing, resulting in a significant reduction in the waterproof effect. At the same time, after the coating doctor blade is used for a long time, the edge position will become dull or damaged due to wear. And most of the existing coating doctor blades are integrally formed, so when the edge position becomes dull or damaged, it is often necessary to scrap the entire coating doctor blade. The blade body of the coating doctor blade often has a relatively complete structure, resulting in waste of a lot of materials and economic costs when the edge position is damaged and the entire coating doctor blade needs to be scrapped, which is not convenient for operators to use.

[0004] Therefore, a thermal paper provided with a surface thermal color developer layer and a coating doctor blade thereof is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides a thermal paper provided with a surface thermal color developer layer and a coating doctor blade thereof to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

Plug holes are formed on the surface of the cutting edge, and a clamping groove is formed at the top of the cutting edge. The bottom of the blade body is clamped inside the clamping groove. An installation mechanism is provided on the inner surface of the blade body. The installation mechanism includes a cavity, which is formed on the inner surface of the blade body. A knob is movably connected to the right side of the blade body. A lead screw is fixedly connected to the left side of the knob.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In the following text, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the accompanying drawings and the description are considered to be exemplary in nature rather than restrictive.

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1

[0029] As Figure 1-2 shown, an embodiment of the present invention provides a thermal paper provided with a surface thermosensitive color developer layer, including a thermal paper body 6. The thermal paper body 6 includes a paper base bottom layer 61. An adhesive layer 7 is coated on the outer side of the paper base bottom layer 61. A thermosensitive color developer layer 8 is coated on the outer side of the adhesive layer 7. A waterproof layer 9 is arranged on the outer side of the thermosensitive color developer layer 8. The waterproof layer 9 includes a first waterproof layer 901, a second waterproof layer 902, and a third waterproof layer 903.

[0030] The first waterproof layer 901 is coated on the outer side of the thermosensitive color developer layer 8. The second waterproof layer 902 is coated on the outer side of the first waterproof layer 901. The third waterproof layer 903 is coated on the outer side of the second waterproof layer 902.

[0031] The material of the first waterproof layer 901 is nano waterproof coating. The material of the second waterproof layer 902 is polyurethane waterproof coating. The material of the third waterproof layer 903 is acrylamide waterproof coating.

[0032] Specifically, as Figure 1 、 Figure 2 shown, by arranging the first waterproof layer 901, the second waterproof layer 902, and the third waterproof layer 903, the waterproof effect can be achieved on the thermal paper body 6, thereby improving the strength of the thermal paper body 6. By arranging the first waterproof layer 901, the second waterproof layer 902, and the third waterproof layer 903, due to the characteristics of their materials, the thermal paper body 6 can have waterproof characteristics, thereby avoiding the situation that the service life of the thermal paper body 6 is reduced due to the interference of water sources.

[0033] As Figures 3-6As shown in the figure, it includes a blade body 1. A cutting edge 3 is provided at the bottom of the blade body 1. Insertion holes 5 are formed on the surface of the cutting edge 3, and a clamping groove 4 is formed at the top of the cutting edge 3. The bottom of the blade body 1 is clamped inside the clamping groove 4. An installation mechanism 2 is formed on the inner surface of the blade body 1. The installation mechanism 2 includes a cavity 201 which is formed on the inner surface of the blade body 1. A knob 202 is movably connected to the right side of the blade body 1. A lead screw 203 is fixedly connected to the left side of the knob 202. Threaded blocks 204 are threadedly connected to both the left and right sides of the surface of the lead screw 203. Connecting rods 205 are movably connected to the front and back sides of the two threaded blocks 204 through rotating shafts. Mounting plates 206 are movably connected to the outer sides of the four connecting rods 205. Bolts 207 are fixedly installed on the outer sides of the two mounting plates 206.

[0034] Insertion slots 209 are formed on both the front and back sides of the blade body 1. The bolts 207 penetrate through the inner cavities of the insertion holes 5 and the insertion slots 209 and extend to the outside of the cutting edge 3.

[0035] A limiting rod 210 is fixedly installed in the inner cavity of the cavity 201. The inner surfaces of the two threaded blocks 204 are slidably connected to the surface of the limiting rod 210.

[0036] The insertion holes 5 and the insertion slots 209 are in the same horizontal direction, and the inner cavities of the insertion holes 5 and the insertion slots 209 are interconnected in the middle.

[0037] Fourteen nuts 208 are threadedly connected to the surfaces of the fourteen bolts 207. The inner sides of the fourteen nuts 208 are in contact with the surface of the clamping groove 4.

[0038] Specifically, as shown in Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 By providing the insertion slots 209, the movement of the bolts 207 can be limited to prevent the bolts 207 from shifting during movement, thus affecting the replacement work of the cutting edge 3. By providing the limiting rod 210, the movement of the threaded blocks 204 can be limited to prevent the threaded blocks 204 from shifting during movement, thereby affecting the installation or disassembly work of the cutting edge 3. By providing the insertion slots 209 and the insertion holes 5, since they are in the same horizontal direction and interconnected, it is convenient for the bolts 207 to freely enter and exit, thereby improving the stability during the mutual installation of the blade body 1 and the cutting edge 3. By providing the nuts 208, the length of the bolts 207 extending out of the inner cavity of the cavity 201 can be limited to prevent the bolts 207 from retracting, thus affecting the installation work of the cutting edge 3.

[0039] When the utility model is working: when the cutting edge 3 is damaged after long-term use, the limit on the bolt 207 is released by rotating the nut 208, and then the knob 202 is rotated. When the knob 202 rotates, the lead screw 203 rotates synchronously, and the screw block 204 moves inward along the lead screw 203. When the screw block 204 moves, the connecting rod 205 flips outward and pulls the mounting plate 206 to move inward. As the mounting plate 206 moves, the bolt 207 moves along the inner cavity of the slot 209 into the inner cavity of the cavity 201, so that the limit between the blade 1 and the cutting edge 3 is released. Then, the cutting edge 3 is grasped and pulled downward, so that the blade 1 is removed from the inner side of the card slot 4, thus completing the disassembly of the card slot 4. Then, a new cutting edge 3 is replaced, and the bottom of the blade 1 is clamped on the inner side of the card slot 4. Then, the knob 202 is rotated in the reverse direction, and the lead screw 203 rotates in the reverse direction. At this time, the screw block 204 moves outward, and the connecting rod 205 flips inward due to the movement of the screw block 204 and pushes the mounting plate 206 to move outward. The bolt 207 moves outward along the inner cavities of the slot 209 and the jack 5, and the bolt 207 moves to the outside of the cutting edge 3. Then, the nut 208 is rotated to the surface of the bolt 207, thus completing the connection between the blade 1 and the cutting edge 3.

[0040] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
