A thermal paper processing equipment and processing technology

Abstract

This invention discloses a thermal paper processing equipment and process, including a cylinder with a feed inlet fixedly connected to its side wall. The raw material crushing equipment allows adjustment of the angle between the bottom plate and the feed inlet by rotating a threaded bolt, thereby controlling the descent speed of the raw material on the bottom plate surface and thus controlling the length of the cut material for subsequent papermaking. During processing, the raw material is placed into the feed inlet, and then a servo motor is activated. The servo motor drives a rotating shaft to rotate, which in turn drives a first rotating column on its side wall to rotate. The first rotating column then collides with a semi-circular block, causing the semi-circular block to move a connecting rod towards the inner cavity of the feed inlet. A first spring between the semi-circular block and the cylinder is compressed, generating a rebound force that drives the blade towards the bottom plate surface, cutting the raw material on the bottom plate surface. When the first rotating column moves away from the semi-circular block, the connecting rod, semi-circular block, and blade all return to their original positions under the rebound force of the first spring.

Description

Technical Field

[0001] This invention relates to the field of thermal paper processing technology, specifically to thermal paper processing equipment and processing technology. Background Technology

[0002] Thermosensitive materials are generally made by coating a substrate with a thermosensitive functional coating. The most common substrate used is paper, which has the widest range of applications. There are also some special applications, such as situations where paper substrates are not suitable for use in water or humid environments, or labels for some high-end products, which usually use film-based thermosensitive materials such as BOPP and PET.

[0003] Currently, most thermal materials on the market have a matte or semi-matte finish. This is partly because end-users don't have specific requirements for surface gloss, but more importantly, it's due to the unique properties of thermal coatings and the low solids content of the coatings used in the coating process, which affects the gloss of the finished product. Generally, thermal materials consist of three or more layers: a base insulating layer, a thermal color-developing layer, and a top protective layer. Some materials, to achieve high printing or protective performance, separate the base layer and protective layer into two or more layers. The base coat typically uses calcined kaolin or a mixture with hollow spheres. Due to the high proportion of calcined kaolin and the low amount of adhesive, the base coat is not smooth enough, which is detrimental to improving the final gloss. The color-developing layer generally uses organic components such as colorants, developers, and sensitizers, as well as fillers with certain absorption capacity and relatively low abrasion values, such as light calcium carbonate, silica, and washed kaolin. The adhesive typically uses latex and PVA, and the total amount of adhesive generally does not exceed 10% of the total dry weight. In addition, the solid content of most coatings is... The content of the colorant layer is generally below 30%, so its contribution to gloss is limited. The top coat protective layer coverage is typically no more than 2 g / m², as excessive coverage will affect the clarity of thermal printing, and a thin coating thickness is detrimental to gloss improvement. Regarding the top coat protective layer coating process, to adapt to the ink absorption and drying of the printing process, a large amount of inorganic fillers such as light calcium carbonate is generally used, or a certain amount of silica is added. Silica produces a matting effect, and the large amount of filler used makes it difficult to achieve a sufficient amount of adhesive, thus hindering the achievement of high gloss performance. In summary, the low solids content, low coating amount, low adhesive content, and the use of some matting fillers in the coating all contribute to the difficulty of achieving high gloss performance in traditional thermal coatings.

[0004] The main raw materials for producing thermal paper are crystal violet lactone (CVL) of the triphenylmethane phthalide system, fluorane system, colorless benzoylmethylene blue (BLMB) or spiropyran system. In the initial stage of production, the above raw materials need to be shredded to an appropriate size before papermaking. However, in the current papermaking process, the raw materials are not shredded, which leads to low papermaking efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a thermal paper processing equipment and process to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A thermal paper processing device and processing technology includes a cylinder, a feed inlet fixedly connected to the side wall of the cylinder, a servo motor fixedly connected to the top of the cylinder, a rotating shaft fixedly connected to the bottom of the servo motor, and a cutting assembly installed inside the feed inlet. The device also includes:

[0008] The cutting assembly includes a base plate, a threaded bolt, a blade, a connecting rod, a first spring, a semicircular block, and a first rotating column. The base plate is rotatably mounted on the inner wall of the feed inlet. A threaded bolt is rotatably connected to the bottom end of the base plate. Multiple connecting rods are slidably connected to the side wall of the feed inlet, and the connecting rods penetrate the side wall of the cylinder. A semicircular block is fixedly connected to the end of the connecting rod inside the cylinder. A blade is fixedly connected to the bottom end of the connecting rod inside the feed inlet. A first spring is fixedly connected to the inner wall of the cylinder, and a first rotating column is fixedly connected to the side wall of the rotating shaft.

[0009] Preferably, multiple first rotating columns and semicircular blocks are provided, and the first rotating columns can collide with the semicircular blocks.

[0010] Preferably, a stirring tank is fixedly connected to the bottom end of the cylinder, and a stirring rod is fixedly connected to the side wall of the rotating shaft inside the stirring tank.

[0011] Preferably, a liquid storage tank is fixedly connected to the top of the mixing tank, and a liquid outlet is opened at the bottom of the liquid storage tank, with a one-way valve installed inside the liquid outlet.

[0012] Preferably, a sliding plate is slidably connected to the inner wall of the liquid storage tank, and a second spring is fixedly connected between the sliding plate and the inner wall of the liquid storage tank.

[0013] Preferably, the sliding plate sidewall is fixedly connected to an extrusion column, and the rotating shaft sidewall is fixedly connected to a second rotating column, and the second rotating column and the extrusion column can collide.

[0014] This invention also includes a thermal paper processing technology, comprising the following steps:

[0015] S1. Place the raw material into the feed inlet, and then turn on the servo motor. The servo motor will drive the rotating shaft to rotate. When the rotating shaft rotates, it will drive the first rotating column on its side wall to rotate. Then the first rotating column will collide with the semi-circular block.

[0016] S2. At this time, the semicircular block will drive the connecting rod to move into the inner cavity of the feed port. The first spring between the semicircular block and the cylinder is compressed to generate a rebound force, thereby driving the blade to move towards the bottom plate surface and cut the raw material on the bottom plate surface.

[0017] S3. When the first rotating column moves away from the semicircular block, the connecting rod, the semicircular block and the blade all return to their original positions under the rebound force of the first spring.

[0018] S4. The angle between the bottom plate and the feed inlet can be adjusted by rotating the threaded bolt, thereby controlling the speed at which the raw material falls on the surface of the bottom plate, thus controlling the length of the cut raw material, which is convenient for subsequent papermaking. After the raw material is cut, it enters the cylinder from the feed inlet and then enters the inner cavity of the mixing tank.

[0019] S5. The rotating shaft will drive the second rotating column to rotate, thereby causing the second rotating column to collide with the squeezing column. The squeezing column drives the sliding plate to move, causing the second spring between the sliding plate and the liquid storage tank to be stretched and generate a rebound force.

[0020] S6. The movement of the sliding plate will increase the pressure inside the storage tank. The nutrient solution inside the storage tank will flow out from the outlet into the mixing tank. Combined with the rotation of the stirring rod driven by the rotating shaft, the raw materials will be mixed evenly. Beneficial effects

[0021] This invention provides a thermal paper processing equipment and process, which has the following beneficial effects:

[0022] This raw material crushing equipment allows adjustment of the angle between the bottom plate and the feed inlet by rotating the threaded bolt, thereby controlling the descent speed of the raw material on the bottom plate surface and thus controlling the length of the cut raw material for subsequent papermaking. During processing, the raw material is placed into the feed inlet, and then the servo motor is turned on. The servo motor drives the rotating shaft to rotate, which in turn drives the first rotating column on its side wall to rotate. The first rotating column then collides with the semicircular block. At this time, the semicircular block drives the connecting rod to move into the inner cavity of the feed inlet. The first spring between the semicircular block and the cylinder is compressed and generates a rebound force, which drives the blade to move towards the bottom plate surface and cuts the raw material on the bottom plate surface. When the first rotating column moves away from the semicircular block, under the rebound force of the first spring, the connecting rod, semicircular block and blade all return to their original positions.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figure 1-4 A thermal paper processing device includes a cylinder 1, a feed inlet 101 fixedly connected to the side wall of the cylinder 1, a servo motor 102 fixedly connected to the top of the cylinder 1, a rotating shaft 103 fixedly connected to the bottom of the servo motor 102, and a cutting assembly installed inside the feed inlet 101. The device also includes:

[0030] The cutting assembly includes a base plate 2, a threaded bolt 201, a blade 202, a connecting rod 203, a first spring 204, a semicircular block 205, and a first rotating column 206. The base plate 2 is rotatably mounted on the inner wall of the feed inlet 101. The bottom end of the base plate 2 is rotatably connected to the threaded bolt 201. Multiple connecting rods 203 are slidably connected to the side wall of the feed inlet 101, and the connecting rods 203 penetrate the side wall of the cylinder 1. The end of the connecting rod 203 located inside the cylinder 1 is fixedly connected to the semicircular block 205. The bottom end of the connecting rod 203 located inside the feed inlet 101 is fixedly connected to the blade 202. The semicircular block 205 is fixedly connected to the inner wall of the cylinder 1 with the first spring 204. The side wall of the rotating shaft 103 is fixedly connected to the first rotating column 206.

[0031] Multiple first rotating pillars 206 and semicircular blocks 205 are provided, and the first rotating pillars 206 can collide with the semicircular blocks 205.

[0032] It should be noted that: when the raw material is placed into the feed inlet 101, the servo motor 102 is turned on. The servo motor 102 will drive the rotating shaft 103 to rotate. When the rotating shaft 103 rotates, it will drive the first rotating column 206 on its side wall to rotate. Then the first rotating column 206 will collide with the semi-circular block 205. At this time, the semi-circular block 205 will drive the connecting rod 203 to move into the inner cavity of the feed inlet 101. The first spring 204 between the semi-circular block 205 and the cylinder 1 is compressed and generates a rebound force, thereby driving the blade 202 to move towards the surface of the bottom plate 2 and cut the raw material on the surface of the bottom plate 2. When the first rotating column 206 moves away from the semi-circular block 205, under the action of the rebound force of the first spring 204, the connecting rod 203, the semi-circular block 205 and the blade 202 all return to their original positions. In addition, the angle between the bottom plate 2 and the feed inlet 101 can be adjusted by rotating the threaded bolt 201, thereby controlling the descent speed of the raw material on the surface of the bottom plate 2, thereby controlling the length of the cut raw material, which is convenient for subsequent paper making.

[0033] Reference Figure 1-4 A mixing tank 3 is fixedly connected to the bottom end of the cylinder 1, and a stirring rod 301 is fixedly connected to the side wall of the rotating shaft 103 inside the mixing tank 3.

[0034] A liquid storage tank 302 is fixedly connected to the top of the mixing tank 3. A liquid outlet 303 is opened at the bottom of the liquid storage tank 302, and a one-way valve is provided in the inner cavity of the liquid outlet 303.

[0035] A sliding plate 304 is slidably connected to the inner wall of the liquid storage tank 302, and a second spring 305 is fixedly connected between the sliding plate 304 and the inner wall of the liquid storage tank 302.

[0036] A pressing column 306 is fixedly connected to the side wall of the sliding plate 304, and a second rotating column 307 is fixedly connected to the side wall of the rotating shaft 103, and the second rotating column 307 and the pressing column 306 can collide.

[0037] It should be noted that after the raw materials are cut, they enter the cylinder 1 through the feed inlet 101 and then into the inner cavity of the mixing tank 3. At the same time, the rotating shaft 103 drives the second rotating column 307 to rotate, causing the second rotating column 307 to collide with the extrusion column 306. The extrusion column 306 drives the sliding plate 304 to move, causing the second spring 305 between the sliding plate 304 and the storage tank 302 to be stretched and generate a rebound force. At the same time, the movement of the sliding plate 304 will increase the pressure in the inner cavity of the storage tank 302. The nutrient solution in the inner cavity of the storage tank 302 flows out from the outlet 303 into the inner cavity of the mixing tank 3. Combined with the rotation of the stirring rod 301 driven by the rotating shaft 103, the raw materials can be mixed evenly.

[0038] This invention also includes a thermal paper processing technology, comprising the following steps:

[0039] S1. Place the raw material into the feed port 101, and then turn on the servo motor 102. The servo motor 102 will drive the rotating shaft 103 to rotate. When the rotating shaft 103 rotates, it will drive the first rotating column 206 on its side wall to rotate. Then the first rotating column 206 will collide with the semi-circular block 205.

[0040] S2. At this time, the semicircular block 205 will drive the connecting rod 203 to move towards the inner cavity of the feed port 101. The first spring 204 between the semicircular block 205 and the cylinder 1 will be compressed to generate a rebound force, thereby driving the blade 202 to move towards the surface of the bottom plate 2 and cut the raw material on the surface of the bottom plate 2.

[0041] S3. When the first rotating column 206 moves away from the semicircular block 205, under the rebound force of the first spring 204, the connecting rod 203, the semicircular block 205 and the blade 202 all return to their original positions.

[0042] S4. The angle between the bottom plate 2 and the feed inlet 101 can be adjusted by rotating the threaded bolt 201, thereby controlling the speed at which the raw material falls on the surface of the bottom plate 2, and thus controlling the length of the cut raw material, which is convenient for subsequent papermaking. After the raw material is cut, it enters the cylinder 1 from the feed inlet 101 and then enters the inner cavity of the mixing tank 3.

[0043] S5. The rotating shaft 103 will drive the second rotating column 307 to rotate, thereby causing the second rotating column 307 to collide with the extrusion column 306. The extrusion column 306 drives the sliding plate 304 to move, causing the second spring 305 between the sliding plate 304 and the liquid storage tank 302 to be stretched and generate a rebound force.

[0044] S6. The movement of the sliding plate 304 will increase the pressure inside the storage tank 302. The nutrient solution inside the storage tank 302 flows out from the outlet 303 into the inner cavity of the mixing tank 3. Combined with the rotation of the stirring rod 301 driven by the rotating shaft 103, the raw materials are mixed evenly.

[0045] Working principle: Raw materials are placed into the feed inlet 101, and then the servo motor 102 is turned on. The servo motor 102 drives the rotating shaft 103 to rotate. When the rotating shaft 103 rotates, it drives the first rotating column 206 on its side wall to rotate. Then the first rotating column 206 collides with the semi-circular block 205. At this time, the semi-circular block 205 drives the connecting rod 203 to move into the inner cavity of the feed inlet 101. The first spring 204 between the semi-circular block 205 and the cylinder 1 is compressed and generates a rebound force, thereby driving the blade 202 to move towards the surface of the bottom plate 2 and cut the raw materials on the surface of the bottom plate 2. When the first rotating column 206 moves away from the semi-circular block 205, under the action of the rebound force of the first spring 204, the connecting rod 203, the semi-circular block 205 and the blade 202 all return to their original positions. In addition, the bottom plate can be adjusted by rotating the threaded bolt 201. The angle between the bottom plate 2 and the feed inlet 101 controls the descent speed of the raw material on the surface of the bottom plate 2, thereby controlling the length of the cut raw material for subsequent papermaking. After the raw material is cut, it enters the cylinder 1 from the feed inlet 101 and then enters the inner cavity of the mixing tank 3. At the same time, the rotating shaft 103 drives the second rotating column 307 to rotate, causing the second rotating column 307 to collide with the extrusion column 306. The extrusion column 306 drives the sliding plate 304 to move, causing the second spring 305 between the sliding plate 304 and the liquid storage tank 302 to be stretched and generate a rebound force. At the same time, the movement of the sliding plate 304 will increase the pressure in the inner cavity of the liquid storage tank 302. The nutrient solution in the inner cavity of the liquid storage tank 302 flows out from the outlet 303 into the inner cavity of the mixing tank 3. Combined with the rotation of the stirring rod 301 driven by the rotating shaft 103, the raw material can be mixed evenly.
