Description

Technical Field

[0001] This invention belongs to the field of paper product processing technology, specifically a drying device for processing printed paper products. Background Art

[0002] Printed paper products refer to various products made from paper as the basic material and through printing processes. These products include, but are not limited to, books, magazines, newspapers, brochures, posters, greeting cards, envelopes, and packaging boxes. After printing, the ink usually adheres quickly to the paper product. However, the ink also contains some volatile substances. When exposed to heat or water molecules during subsequent sale or use, the ink may peel off or remain on the printed paper.

[0003] The drying process of printed paper products is a crucial step in the production process. It ensures that volatile substances in the printing inks detach from the ink, thereby improving the ink's adhesion and allowing it to adhere better to the paper products. In existing technologies, a hot air blower is typically used to raise the temperature of the ink on the paper. However, this single technical method can cause the paper to shrink or deform during the drying process, leading to a decrease in the quality of the paper after drying. Therefore, we propose a drying device for printing paper products. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a drying device for printing paper products, which solves the problem that when paper is blown by a hot air blower, the paper may shrink or deform, which in turn leads to a decrease in paper quality after the drying process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drying device for processing printed paper products, comprising a drying box and printing paper, wherein a fan is fixedly mounted on the side of the drying box, and further comprising... A steel pipe that is connected to the air outlet of the fan and fixed to the outside of the drying box; Two drying components connected to both ends of a steel pipe are symmetrically arranged at the top and bottom of a drying box. The drying components are used to dry the ink on the printing paper. Four clamping components are installed inside the drying box. Each pair of clamping components arranged vertically forms a group. One group of clamping components is used to guide two drying components. The printing paper is clamped by the two clamping components.

The rolling assembly includes two bidirectional spring telescopic plates. The opposite surfaces of the two bidirectional spring telescopic plates are connected to two rollers via bearings. A gear is fitted at both ends of the two rollers. The opposite surfaces of the two bidirectional spring telescopic plates are connected by two arc-shaped plates. Two double-layer toothed plates are symmetrically arranged inside the drying box. Each roller is connected to two guides at both ends by spring plates arranged at equal angles around the circumference. A spring telescopic plate is hinged to the bottom of the guide, and a pressing plate is movably arranged on the outer periphery of the spring telescopic plate. A limit plate is provided on the top of the spring telescopic plate.

[0006] Preferably, the guide consists of a metal ring and a telescopic plate. The metal ring is fixedly connected to the telescopic plate, and the inner wall of the metal ring has a groove that matches the spring plate. The bottom of the telescopic plate is hinged to the spring telescopic plate.

[0007] Preferably, one of the bidirectional spring telescopic plates is connected to the side of the limiting block, each of the gears meshes with a double-layer toothed plate, and the printing paper is clamped between the two rollers and the extrusion plate.

[0008] Preferably, the limiting component includes a movable plate movably disposed on the inner wall of the drying box, the top of the movable plate being elastically connected to the inner wall of the drying box via a spring, a trigger plate being hinged to the bottom of the movable plate, and a spring telescopic plate being hinged to the side of the movable plate.

[0009] Preferably, the trigger plate two is fixedly mounted on the side of the extrusion plate, the bottom of the spring telescopic plate is hinged to the extrusion plate, the side of the trigger plate two is arc-shaped, the spring telescopic plate is at its maximum extension length, and the number of the limiting components is the same as that of the extrusion plate.

[0010] Preferably, the drying box is provided with a hydraulic cylinder and a triangular block connected to the movable end of the hydraulic cylinder. There are four hydraulic cylinders and four triangular blocks, which are distributed at the four corners inside the drying box. The triangular blocks are located between the arc surfaces of every two trigger plates.

[0011] Preferably, one of the drying components includes an air storage box fixed to the bottom of the drying box, a heating wire is provided inside the air storage box, a plurality of corrugated tubes are equidistantly arranged inside the drying box, an air cylinder is fixedly installed at the top of each corrugated tube, each air cylinder is connected to each other through a linkage plate, a pusher plate is hinged to one side of the linkage plate, and a limit plate is movably connected to the other side of the linkage plate.

[0012] Preferably, the bottom of the pusher plate is hinged to the drying box, the drying box and the pusher plate are supported by a spring sheet, and the limiting plate is fixed inside the drying box.

[0013] Preferably, the clamping assembly further includes a pressure block fixed to the semi-circular plate, the position of which coincides with the position of the push plate.

[0014] Preferably, the drying box has a discharge port and a feed port on both sides, and the side of the drying box with the discharge port is provided with an arc-shaped baffle and a receiving plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a combination of a crushing assembly and a clamping assembly. A roller, driven by a spring plate, rotates a guide. A telescopic rod within one of the guides rotates, causing a telescopic plate in a relatively opposite position to tilt the extrusion plate via the spring-loaded telescopic plate. The extrusion plate no longer adheres to the printing paper. As the curved plate moves, it gradually contacts and forces the semi-circular plate and the telescopic plate to move upwards. This causes the extrusion plate and the telescopic plate to no longer clamp the edges of the printing paper. At this point, hot air contacts and dries the four edges of the printing paper. This avoids the situation in normal drying where the edges of the printing paper are dried first, leading to over-drying and deformation when the paper is fully dried. This also reduces shrinkage and deformation of the printing paper during the drying process, further improving the quality of the dried printing paper.

[0016] This invention utilizes a combination of a rolling assembly and a limiting block. The limiting block moves laterally along the inner wall of the drying box. When the motor rotates its output shaft, which has a reciprocating threaded groove, the limiting block drives a bidirectional spring telescopic plate to move horizontally. At this time, the bidirectional spring telescopic plate drives the gear and roller to move. The gear drives the roller to rotate through a double-layer toothed plate. During this process, the roller reciprocates and rolls the printing paper. Furthermore, the continuous rolling of the roller also prevents it from scraping the ink on the printing paper during the rolling and flattening process, thus avoiding unclear fonts.

[0017] This invention, through the coordinated arrangement of structures such as the crushing component and the drying component, allows the gap between two extrusion plates to widen and no longer clamp the printing paper. The extrusion plates then push the telescopic plate via a trigger plate. The movable end of the telescopic plate moves the semi-circular plate and the pressure block, pressing the guide plate. The guide plate, through a linkage plate, tilts the air cylinder. The corrugated pipe allows communication between the air cylinder and the drying box, and the air inside the air storage box can still enter the drying box through the corrugated pipe and the air cylinder. At this point, the printing paper is blown out of the drying box by the tilted airflow and falls onto the receiving plate, further reducing the labor and cost of manual operation.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 10As shown, the present invention provides a drying apparatus for processing printed paper products, including a drying box 1 and printing paper 11. A fan 3 is fixedly mounted on the side of the drying box 1, and the apparatus also includes... A steel pipe 4 that is connected to the air outlet of the fan 3 and fixed to the outside of the drying box 1; Two drying components 7 are connected to both ends of the steel pipe 4. The two drying components 7 are symmetrically arranged at the top and bottom of the drying box 1. The drying components 7 are used to dry the ink on the printing paper 11. Four clamping components 2 are set inside the drying box 1. Each pair of clamping components 2 arranged vertically forms a group. One group of clamping components 2 is used to guide the two drying components 7 to work. The printing paper 11 is clamped by the two clamping components 2. The clamping assembly 2 includes two spring telescopic rods 21 fixed inside the drying box 1. The movable ends of the two spring telescopic rods 21 are connected to telescopic plates 22, and semi-circular plates 23 are fixed to the sides of the telescopic plates 22. The motor 5 is fixed inside the drying box 1, and the output shaft of the motor 5 is threadedly connected to the limit block 6; The crushing component 9 is installed inside the drying box 1, and the two sides of the crushing component 9 are hinged to the inner wall of the drying box 1 through the limiting component 8. The rolling assembly 9 includes two bidirectional spring telescopic plates 91. The opposite surfaces of the two bidirectional spring telescopic plates 91 are connected to two rollers 94 through bearings. A gear 93 is fitted at both ends of the two rollers 94. The opposite surfaces of the two bidirectional spring telescopic plates 91 are connected by two arc-shaped plates 92. Two double-layer toothed plates 95 are symmetrically arranged inside the drying box 1. Each roller 94 has two guides 96 connected to its two ends by spring plates 97 arranged at equal angles around the circumference. A spring telescopic plate 98 is hinged to the bottom of the guide 96. A pressing plate 90 is movably arranged on the outer periphery of the spring telescopic plate 98. A limit plate 99 is provided on the top of the spring telescopic plate 98.

[0022] The guide 96 is composed of a metal ring 961 and a telescopic plate 962. The metal ring 961 is fixedly connected to the telescopic plate 982. The inner wall of the metal ring 961 has a groove that matches the spring plate 97. The bottom of the telescopic plate 962 is hinged to the spring telescopic plate 98.

[0023] One of the bidirectional spring telescopic plates 91 is connected to the side of the limiting block 6, each gear 93 meshes with the double-layer toothed plate 95, and the printing paper 11 is clamped between the two rollers 94 and the pressing plate 90.

[0024] Using the above scheme: heat is dissipated from the inside of the drying component 7, and the fan 3 blows the heat from the drying component 7 into the drying box 1 through the steel pipe 4 and uses it to dry the printing paper 11; The limiting block 6 moves laterally within the inner wall of the drying box 1. When the motor 5 rotates its output shaft with reciprocating threaded grooves, the limiting block 6 will drive the bidirectional spring telescopic plate 91 to move reciprocally in the horizontal direction. At this time, the bidirectional spring telescopic plate 91 drives the gear 93 and the roller 94 to move. The gear 93 drives the roller 94 to rotate through the double-layer toothed plate 95. During this process, the roller 94 will reciprocate and crush the printing paper 11. Since there are two rollers 94, the printing paper 11 can be crushed better, thereby reducing the drying time of the printing paper 11. Before drying, the ink on the printing paper 11 is in a dry state due to shrinkage and deformation. Drying is to evaporate and remove volatile substances in the ink and improve the curing effect of the ink. The roller 94 in the rolling state will intermittently contact the ink, so that it can come into contact with the volatile substances that are separated from the ink, thereby accelerating the evaporation of volatile substances. Furthermore, the continuous rolling state of the roller 94 can also prevent it from scratching the ink on the printing paper 11 during the rolling process, thus making the font unclear. like Figure 6 as well as Figure 7 The roller 94 and guide 96 in the roller 94 will rotate through the spring plate 2 97 during the rolling process. The telescopic rod in one of the guides 96 will rotate and be limited to a vertical state by the limiting plate 2 99. At this time, the spring plate 2 97 will disengage from the groove on the metal ring. The roller 94 can continue to rotate and perform the crushing work. The telescopic plate in the opposite position will drive the extrusion plate 90 to tilt through the spring telescopic plate 2 98. The extrusion plate 90 will no longer be in contact with the printing paper 11. During the movement of the arc plate 92, it will gradually contact and force the semi-circular plate 23 and the telescopic plate 22 to move upward. As a result, the telescopic plate 22 will no longer clamp the corners of the printing paper 11. At this time, the hot air will contact and dry the four sides of the printing paper 11. This avoids the situation where the edges of the printing paper 11 will be dried first under normal drying conditions. When the printing paper 11 is completely dried, its edges will bend and deform due to over-drying. This further improves the quality of the printing paper 11 after drying.

[0025] like Figure 2 , Figure 3 , Figure 8 As shown, the limiting component 8 includes a flap 81 that is movably disposed on the inner wall of the drying box 1. The top of the flap 81 is elastically connected to the inner wall of the drying box 1 by a spring 82. A trigger plate 84 is hinged to the bottom of the flap 81, and a spring telescopic plate 83 is hinged to the side of the flap 81.

[0026] Trigger plate 2 84 is fixed to the side of extrusion plate 90, the bottom of spring telescopic plate 83 is hinged to extrusion plate 90, the side of trigger plate 2 84 is arc-shaped, spring telescopic plate 83 is at its maximum extension length, and the number of limiting components 8 is the same as that of extrusion plate 90.

[0027] like Figure 3 and Figure 8 As shown, the interior of the drying box 1 is equipped with a hydraulic cylinder 10 and a triangular block 12 connected to the movable end of the hydraulic cylinder 10. There are four hydraulic cylinders 10 and four triangular blocks 12, which are distributed in the four corners of the interior of the drying box 1. The triangular blocks 12 are located between the arc surfaces of every two trigger plates 84.

[0028] The above scheme is adopted: one side of the extrusion plate 90 is hinged to the spring telescopic plate 83 via the trigger plate 2 84. When the extrusion plate 90 moves, due to the elastic compression of the spring 82, the extrusion plate 90 can only be tilted, so that the edge of the printing paper 11 is dried. After the drying work is completed, the hydraulic cylinders 10 at the four corners inside the drying box 1 can be activated, which forces the triangular blocks 12 to be inserted between the arc surfaces of each two trigger plates 2 84. It should be noted that the hinge point between the movable plate 81 and the trigger plate 2 84 is located at the top of the triangular blocks 12 and the hydraulic cylinder 10. The triangular blocks 12 are continuously inserted, which can increase the gap between each two extrusion plates 90 through the trigger plate 2 84. While the gap is increasing, since the spring telescopic plate 83 has reached its maximum extension length, it pulls the trigger plate 2 84 to always be in a horizontal state, so that the printing paper 11 is no longer clamped by the extrusion plate 90. The operator can then start the next drying work, thereby reducing the cost of manual labor.

[0029] like Figure 1 , Figure 2 , Figure 9 As shown in Figures 1 and 10, one of the drying components 7 includes an air storage box 71 fixed to the bottom of the drying box 1. A heating wire 72 is provided inside the air storage box 71. Several corrugated tubes 73 are equidistantly arranged inside the drying box 1. An air cylinder 74 is fixedly installed on the top of each corrugated tube 73. Each air cylinder 74 is connected to each other through a linkage plate 75. A pusher plate 76 is hinged to one side of the linkage plate 75, and a limit plate 77 is movably connected to the other side of the linkage plate 75.

[0030] The bottom of the pusher plate 76 is hinged to the drying box 1. The drying box 1 and the pusher plate 76 are supported by a spring plate 78. The limiting plate 77 is fixed inside the drying box 1.

[0031] The clamping assembly 2 also includes a pressure block 24 fixed on the semi-circular plate 23, the position of which coincides with the position of the pusher plate 76.

[0032] Using the above scheme: start the heating wire 72 and make it generate heat. After the preheating is completed, start the fan 3. It delivers the external air into the air storage box 71 through the steel pipe 4. Finally, it enters the interior of the drying box 1 through the corrugated pipe 73 and the air cylinder 74. The heat generated by the heating wire 72 will also be brought in and the printing paper 11 will be dried. like Figure 10When the gap between the trigger plate 25 and the extrusion plate 90 widens and no longer clamps the printing paper 11, the extrusion plate 90 will also push the telescopic plate 22 through the trigger plate 25. At this time, the telescopic plate 22 is compressed, and its movable end drives the semi-circular plate 23 and the pressure block 24 to move and press the push plate 76. At this time, the push plate 76 will also push the air cylinder 74 to an inclined position through the linkage plate 75. It should be noted that the corrugated pipe 73 can connect the air cylinder 74 with the drying box 1, and the air inside the air storage box 71 can still enter the drying box 1 through the corrugated pipe 73 and the air cylinder 74. The maximum temperature that the corrugated pipe 73 can withstand is greater than the maximum temperature released by the heating wire 72. When the pressure plate 90 stops clamping the printing paper 11, the air cylinder 74 will also change the air direction from vertical to inclined. At this time, the printing paper 11 can be blown out of the interior of the drying box 1 by the inclined air direction, which further reduces the labor and cost of manual operation.

[0033] like Figure 1 As shown, the drying box 1 has a discharge port and a feed port on both sides. The side of the drying box 1 with the discharge port is provided with an arc-shaped baffle 13 and a receiving plate 14. The arc-shaped baffle 13 is used to prevent the printing paper 11 from falling to the ground, and the receiving plate 14 is used to place the dried printing paper 11.

[0034] The above solution is adopted: when the printing paper 11 is blown out of the drying box 1 by the drying component 7, the arc-shaped baffle on its side will block the printing paper 11 and make it fall onto the receiving plate, thus preventing the printing paper 11 from falling to the ground and being absorbed by dust.

[0035] Working principle and usage process of this invention: Start the heating wire 72 to generate heat. After preheating, start the fan 3, which delivers external air into the air storage box 71 through the steel pipe 4. Finally, the air enters the interior of the drying box 1 through the corrugated pipe 73 and the air cylinder 74. The heat generated by the heating wire 72 will also be carried in and the printing paper 11 will be dried. When the motor 5 rotates its output shaft with a reciprocating threaded groove, the limit block 6 will drive the bidirectional spring telescopic plate 91 to move reciprocally in the horizontal direction. At this time, the bidirectional spring telescopic plate 91 drives the gear 93 and the roller 94 to move. The gear 93 drives the roller 94 to rotate through the double-layer toothed plate 95. During this process, the roller 94 will reciprocate to crush the printing paper 11. During the rolling of the roller 94, the guide 96 will be rotated by the spring plate 2 97. The telescopic rod in one of the guides 96 will rotate and be restricted to a vertical state by the limiting plate 2 99. At this time, the spring plate 2 97 will disengage from the groove on the metal ring. The roller 94 can continue to rotate and perform crushing work. The telescopic plate in the opposite position will drive the extrusion plate 90 to move through the spring telescopic plate 2 98. One side of the extrusion plate 90 is hinged to the spring telescopic plate 83 through the trigger plate 2 84. When the extrusion plate 90 moves, due to the elastic compression of the spring 82, the extrusion plate 90 can only be tilted. The extrusion plate 90 will no longer be in contact with the printing paper 11. During the movement of the arc plate 92, it will gradually contact and force the semicircular plate 23 and the telescopic plate 22 to move upward, so that the telescopic plate 22 will no longer clamp the corner of the printing paper 11. The printing paper 11 will also be dried. After the drying process is completed, the hydraulic cylinders 10 at the four corners inside the drying box 1 can be activated, which forces the triangular blocks 12 to be inserted between the arc surfaces of each pair of trigger plates 84. It should be noted that the hinge point between the movable plate 81 and the trigger plate 84 is located at the top of the triangular blocks 12 and the hydraulic cylinder 10. As the triangular blocks 12 are continuously inserted, the gap between each pair of extrusion plates 90 can be increased through the trigger plates 84. While the gap is increasing, the spring telescopic plate 83 can pull the trigger plates 84 to keep them in a horizontal state, so that the printing paper 11 is no longer clamped by the extrusion plates 90. The extrusion plate 90 will also push the telescopic plate 22 through the trigger plate 25. At this time, the telescopic plate 22 is compressed, and its movable end drives the semi-circular plate 23 and the pressure block 24 to move and press the push plate 76. At this time, the push plate 76 will also push the air cylinder 74 to an inclined position through the linkage plate 75. At this time, the printing paper 11 can be blown out of the interior of the drying box 1 by the inclined wind direction. The arc-shaped baffle on the side of the drying box 1 will block the printing paper 11 and make it fall onto the receiving plate.
