Description

Technical Field

[0001] The present invention relates to the technical field of paper product production, and particularly relates to a drying device for paper product production. Background Art

[0002] Since ancient times, paper has been widely used in human production and life. With the development of the times, the popularity of paper products in life is getting higher and higher, and people's dependence on paper products is also increasing. Paper products can be seen everywhere in people's living environment, whether in daily life or in the daily work process, and have become one of the essential supplies in life. Drying is an essential step in the production process of paper products, and the quality of drying directly affects the quality of the produced paper products.

[0003] The patent document with the publication number CN212720751U discloses a drying device for paper product production, including a drying box. A heating mechanism is fixedly connected to the inner wall of the drying box. Two symmetrically distributed rectangular through holes are opened on the outer walls on both sides of the drying box. The upper surface and the lower surface of the drying box are fixedly communicated with a U-shaped pipe. An air extraction pump is fixedly connected to the upper surface of the drying box. The air inlet end of the air extraction pump is fixedly communicated with the pipe wall of the U-shaped pipe. The output end of the air extraction pump is fixedly communicated with a connecting pipe. In the above design, when drying paper products, only one side of the paper products can be dried. When it is necessary to dry the other side, it is necessary to turn the paper products over, making the operation relatively difficult. Therefore, we propose a drying device for paper product production to solve this problem. Summary of the Invention

[0004] The purpose of the present invention is to provide a drying device for paper product production to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A drying device for paper product production, comprising:

[0007] A conveying mechanism for conveying paper products. The conveying mechanism includes two vertical plates and two transmission shafts. A plurality of support columns are fixedly connected between the two vertical plates. Both transmission shafts are rotatably connected between the two vertical plates. Two rotating plates are fixedly sleeved on the outer side of the transmission shafts. The same connecting column is fixedly connected between the two rotating plates on the same side;

[0008] A blowing mechanism for generating hot air. The blowing mechanism is provided in two groups, and the two groups of blowing mechanisms are respectively arranged above and below the conveying mechanism. The blowing mechanism includes a blowing frame, an electric heating net and a plurality of fan blades. The electric heating net is fixedly installed in the fixed frame, and one end of the fan blade is fixedly connected with a rotating shaft. The rotating shaft is rotatably connected to the inner wall of the blowing frame.

[0009] Preferably, one side of the air blowing frame is open, and the other side of the air blowing frame is fixedly connected with two vertical plates. A same driving shaft is rotatably connected between the two vertical plates. The other end of the rotating shaft is fixedly connected with a driven bevel gear. A plurality of driving bevel gears are fixedly installed on the driving shaft, and the driving bevel gears are meshed with the corresponding driven bevel gears.

[0010] Preferably, a rotating motor is fixedly installed on one side of the air blowing frame. A transmission gear is fixedly connected to the output shaft of the rotating motor. Four cross beams are fixedly connected between the two vertical plates. Rack gears are fixedly installed on two of the cross beams, and the transmission gear is meshed with the rack gears.

[0011] Preferably, an L-shaped plate is fixedly installed on one side of the air blowing frame. A driving motor is fixedly installed inside the L-shaped plate, and one end of the driving shaft is fixedly connected to the output end of the driving motor.

[0012] Preferably, a limiting ring is fixedly sleeved on the outer side of the rotating shaft, and the limiting ring is in movable abutment with the corresponding air blowing frame.

[0013] Preferably, sliding seats are fixedly connected to both sides of the air blowing frame, and the sliding seats are slidably sleeved on the outer sides of the corresponding cross beams.

[0014] Preferably, a same support frame is fixedly connected to the bottoms of the two vertical plates. A conveying motor is fixedly installed on the front side of the support frame. A driving pulley is fixedly connected to the output shaft of the conveying motor. A driven pulley is fixedly connected to the front end of the transmission shaft, and a same belt is installed on the driving pulley and the two driven pulleys for transmission.

[0015] Preferably, the support frame includes four columns and four horizontal beams. The two ends of the horizontal beam are respectively fixedly connected to the corresponding columns, and the top ends of the columns are fixedly connected to the bottoms of the corresponding vertical plates.

[0016] Preferably, strip-shaped limiting protrusions are integrally formed on both sides of the cross beam. A sliding groove is formed inside the sliding seat, and limiting grooves adapted to the strip-shaped limiting protrusions are formed on the inner walls of both sides of the sliding groove.

[0017] Preferably, the plurality of support columns are arranged at equal intervals and uniformly. Both the support columns and the connecting columns are cylindrical. The rotating plate is in movable abutment with one side of the corresponding vertical plate, and the plurality of fan blades are arranged at equal intervals and uniformly. The heating wire mesh is made of nickel-chromium alloy. Nickel-chromium alloy can maintain strength under high temperature conditions, and the resistance characteristics of nickel-chromium alloy are very stable, so that the heating performance of the heating wire mesh is consistent after being electrified, which is easy to control and adjust, and improves the accuracy of the heating process.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, for the drying device for paper product production, by placing the paper product on the support column and then starting the electric heating grid and the driving motor, the driving motor drives the driving shaft to rotate. The driving shaft drives the rotating shaft and the fan blade to rotate through the meshing of a plurality of driving bevel gears and corresponding driven bevel gears. During the rotation of the fan blade, wind is generated, and the air is heated by the provided electric heating grid, thereby generating hot air to dry both the top and bottom of the paper product, improving the drying uniformity.

[0020] 2. In the present invention, for the drying device for paper product production, by starting the rotation to drive the transmission gear to rotate, the transmission gear drives the air blowing frame to move back and forth through the meshing with the rack, thereby drying different positions at the front and back of the paper product.

[0021] 3. In the present invention, for the drying device for paper product production, by starting the conveying motor to drive the driving pulley to rotate, the driving pulley drives two driven pulleys to rotate through the belt. The two driven pulleys drive two transmission shafts to rotate. The two transmission shafts respectively drive two connecting columns to perform circular motion through corresponding rotating plates, thereby intermittently horizontally conveying the paper product. During the conveying process, the indicator plate can be pushed upward, thereby preventing the bottom of the paper product from being blocked to ensure thorough drying.

[0022] 4. In the present invention, for the drying device for paper product production, the two sets of air blowing mechanisms provided can generate drying air on both the upper and lower sides of the paper product at the same time, improving the drying uniformity and efficiency. The traditional single-sided drying method can only heat the paper product from one side, while double-sided drying can heat the paper product from both the upper and lower sides at the same time, enabling the heat to penetrate more evenly into the paper product, thereby accelerating the evaporation rate of moisture. Since double-sided drying can provide more uniform and rapid heat energy, the overall drying time of the paper product is shortened, which is of great significance for improving the throughput of the production line. Double-sided drying equipment is usually equipped with a waste heat recovery system, which can recover and reuse some of the heat. This not only improves energy efficiency but also reduces energy consumption, enhances the quality of paper products. The uniform heating method helps to avoid warping and deformation of the paper caused by single-sided heating, maintaining the flatness of the paper. Appropriate drying temperature and uniform heat distribution help to maintain the integrity of the paper fibers, thereby improving the mechanical strength of the paper. Double-sided drying can effectively avoid the hardening or spotting on the paper surface caused by overheating or uneven heating, ensuring the consistency and smoothness of the paper surface. Since double-sided drying can provide more uniform heating, it reduces the generation of waste products due to uneven heating, thereby reducing production costs, and the provided conveying mechanism can avoid blocking the paper product during the conveying process, ensuring thorough drying.

[0039] In this embodiment, sliding seats 302 are fixedly connected to both sides of the air blowing frame 3. The sliding seats 302 are slidably sleeved on the outer sides of the corresponding cross beams 102, so as to guide the forward and backward movement of the air blowing frame 3.

The drive motor 16 drives the drive shaft 14 to rotate. The drive shaft 14 drives the rotating shaft 13 and the fan blades 10 to rotate through the meshing of a plurality of driving bevel gears 12 and the corresponding driven bevel gears 11. Wind is generated during the rotation of the fan blades 10, and the electrothermal net 301 is used to heat the air, so as to generate hot air to dry both the top and bottom of the paper product, improving the drying uniformity.

[0045] By starting the rotation to drive the transmission gear 19 to rotate, the transmission gear 19 drives the air blowing frame 3 to move back and forth through the meshing with the rack 20, so as to dry different positions of the front and back of the paper product.

[0046] By starting the conveying motor 9 to drive the driving pulley 7 to rotate, the driving pulley 7 drives two driven pulleys 6 to rotate through the belt 8. The two driven pulleys 6 drive two transmission shafts 2 to rotate.
