Description

Technical Field

[0001] This utility model relates to the field of microwave drying of paper tubes, and in particular to a microwave drying machine for paper tubes with good drying integrity. Background Technology

[0002] A microwave paper tube dryer is a device that uses microwave technology to dry paper tubes. It is widely used in the paper processing industry. The microwave dryer utilizes the penetrating power of microwaves to raise the temperature of the material, causing the moisture in the material to vaporize and evaporate. The evaporated water vapor is then removed by a dehumidification system, achieving the purpose of drying the material. This drying method does not require preheating or heat transfer; it directly heats the paper tubes from the inside out simultaneously, resulting in good heating uniformity, even drying, flatness, and minimal deformation. It also has a strong sterilization function, improving the paper tubes' resistance to mold and extending their shelf life. The adhesive bond is strong, significantly improving water resistance and compressive strength. Furthermore, it is energy-saving and environmentally friendly. Currently, in microwave paper tube dryers, most paper tubes are in contact with each other during drying, creating gaps that prevent the escape of humid air. Additionally, residual glue on the paper tube surface may cause the tubes to stick together during the drying process, affecting their integrity. Therefore, it is necessary to propose a microwave paper tube dryer with better drying integrity to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a microwave drying machine for paper tubes with good drying integrity, in order to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a microwave drying machine for paper tubes with good drying integrity, comprising a drying equipment body, the drying equipment body including a conveyor belt, the conveyor belt being disposed within the drying equipment body, the conveyor belt being used to transport paper tubes, conveyor belt baffles being fixed on both sides of the conveyor belt, the conveyor belt baffles being used to prevent paper tubes from falling off from both sides during transport, the conveyor belt including a conveyor belt input end and a conveyor belt output end, and a paper tube feeding mechanism being provided on one side of the conveyor belt input end.

[0005] Furthermore, the reciprocating propulsion assembly includes a motor, a limiting block, a first rotating disk, a threaded rod, a second rotating disk, and a propulsion rod, wherein: The motor is fixed to the limiting block. The motor includes a motor output shaft that passes through the limiting block. The bottom center of the first rotating disk is fixed to the motor output shaft. A slide rail is fixedly connected above the first rotating disk. The slide rail has a U-shaped structure and includes a circular through hole. The circular through hole is located at the axisymmetric center of the slide rail. A boss is fixed at the lower end of the second rotating disk. A threaded hole is provided on the side of the boss. The threaded hole passes through the boss and engages with the slide rail. The boss slides at the U-shaped opening of the slide rail. The threaded hole and the circular through hole are coaxially engaged. A threaded rod passes through the circular through hole and is threadedly connected to the threaded hole. An annular groove is provided above the second rotating disk and is slidably connected to the push rod.

[0006] Furthermore, a support block is fixed to the side of the limiting block facing the main body of the drying equipment. The support block supports the push rod. A cylinder is fixed below the push rod and slides in the annular groove. A rack is fixed below the push rod, and the rack and the cylinder are respectively fixed in different directions of the push rod.

[0007] Furthermore, the paper tube limiting assembly includes a limiting disc, a limiting plate, a second support plate, a first support plate, a feeding channel, a feeding channel, and a roller, wherein: The first support plate is fixedly installed above the conveyor belt baffle. The feeding channel is fixed to the inner side of the first support plate. The feeding channel is inclined relative to the conveyor belt baffle towards the reciprocating propulsion assembly. Two second support plates are respectively fixed to the sides of the two conveyor belt baffles. The inner sides of the two support plates are fixed to the limiting plate. Bearing holes are opened on the two support plates. Bearings are fixed inside the bearing holes. The roller is clearance-fitted between the two bearings. A gear is fixed on the roller. The gear meshes with the rack.

[0008] Furthermore, a disc is fixed on the roller, the roller passes through the center of the disc, and the disc is located below the limiting plate.

[0009] Furthermore, the limiting disc has a V-shaped opening for receiving the paper tube. The disc is tangent to the contact point with the feeding channel. One end of the feeding channel is fixed to the two support plates, and the other end of the feeding channel is fixed to the two conveyor belt baffles.

[0010] Furthermore, the feeding channel is located below the unloading channel and above the conveyor belt, and the feeding channel is inclined toward the main body of the drying equipment relative to the conveyor belt baffle.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model, (1) The paper tube will roll towards the limiting plate through the feeding channel. Under the combined action of the limiting plate and the limiting disc, the paper tube will be stuck and kept stable. When the V-shaped opening on the limiting disc rotates to the position where its opening faces the paper tube, the paper tube will enter the V-shaped opening. As the limiting disc 10 continues to rotate, the paper tube will be sent to the feeding channel. Finally, the paper tube will roll from the feeding channel onto the conveyor belt, completing the entire feeding process.

[0012] (2) By controlling the motor, the first rotating disk drives the second rotating disk to rotate around the axis of the first rotating disk. Since the push rod is restricted by one end of the limit block, it can only perform transverse reciprocating motion. When the second rotating disk rotates, the inner wall of its annular groove will push the push rod to reciprocate. In addition, by adjusting the position of the threaded rod, the axial distance between the first rotating disk and the second rotating disk can be controlled, thereby achieving precise control of the sliding length of the push rod.

[0014] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] like Figure 1 As shown, this utility model provides a technical solution: a microwave drying machine for paper tubes with good drying integrity, including a drying equipment body 1, the drying equipment body 1 including a conveyor belt 2, the conveyor belt 2 being disposed inside the drying equipment body 1, the conveyor belt 2 being used to transport paper tubes, and conveyor belt baffles 3 being fixed on both sides of the conveyor belt 2, the conveyor belt baffles 3 being used to prevent paper tubes from falling off from both sides during transport, the conveyor belt 2 including a conveyor belt input end 201 and a conveyor belt output end 202, and a paper tube feeding mechanism 19 being disposed on one side of the conveyor belt input end 201.

[0016] Precise feeding of paper tubes is achieved through the paper tube feeding mechanism 19 located on one side of the conveyor belt input end. This mechanism can smoothly place paper tubes one by one onto the conveyor belt 2 at certain time intervals. After being conveyed onto the conveyor belt 2, the paper tubes will move along the conveyor belt at a preset speed. Due to the precise control of the paper tube feeding mechanism 19, a certain distance is maintained between each paper tube. In this way, the paper tubes will not come into contact with each other during the drying process, thereby avoiding the sticking caused by poor moisture removal and glue overflow. As the conveyor belt 2 continues to operate, the paper tubes will enter the microwave drying area one by one for drying treatment. During the drying process, microwave energy will act evenly on the surface and inside of the paper tube, thereby quickly removing the moisture in the paper tube and achieving the drying purpose. After drying treatment, the paper tubes will leave the equipment from the conveyor belt output end 202. At this time, the paper tubes have maintained good integrity and can be directly carried out for subsequent collection and processing.

[0017] like Figure 2-3 As shown, in some embodiments, the paper tube feeding mechanism 19 consists of a reciprocating push assembly 20 and a paper tube limiting assembly 15. The reciprocating push assembly 20 is responsible for pushing the paper tubes one by one onto the conveyor belt, while the paper tube limiting assembly 15 is used to ensure that the paper tubes maintain the correct position and posture during the pushing process.

[0018] like Figure 2 and 4 As shown in Figure 6, in some embodiments, the reciprocating propulsion assembly 20 includes a motor 4, a limiting block 5, a first rotating disk 6, a threaded rod 7, a second rotating disk 8, and a propulsion rod 9, wherein: The motor 4 is fixed to the limiting block 5. The motor 4 includes a motor output shaft that passes through the limiting block 5. The bottom center of the first rotating disk 6 is fixed to the motor output shaft. A slide rail 601 is fixedly connected above the first rotating disk 6. The slide rail 601 has a U-shaped structure and includes a circular through hole 602. The circular through hole 602 is opened at the axisymmetric center of the slide rail 601. The second rotating disk 8 has a boss 802 fixed at its lower end. The boss 802 has a threaded hole 803 on its side, which passes through the boss 802. The boss 802 is engaged with the slide rail 601 and slides at the U-shaped opening of the slide rail 601. The threaded hole 803 is coaxially engaged with the circular through hole 602. The threaded rod 7 is threadedly connected to the threaded hole 803 through the circular through hole 602. The second rotating disk has an annular groove 801 on its upper side, which is slidably connected to the push rod 9.

[0019] The limiting block 5 is fixed with a support block 903 on the side facing the main body 1 of the drying equipment. The support block 903 supports the push rod 9. A cylinder 901 is fixed below the push rod 9. The cylinder 901 slides in the annular groove 801. A rack 902 is fixed below the push rod 9. The rack 902 and the cylinder 901 are respectively fixed in different directions of the push rod 9.

[0020] By controlling motor 4, the first rotating disk 6 drives the second rotating disk 8 to rotate around the axis of the first rotating disk 6. Since the push rod 9 is restricted at one end by the limiting block 5, it can only perform lateral reciprocating motion. When the second rotating disk 8 rotates, the inner wall of its annular groove 801 pushes the push rod 9 to reciprocate. Furthermore, by adjusting the position of the threaded rod 7, the axial distance between the first rotating disk 6 and the second rotating disk 8 can be controlled, thereby achieving precise control of the sliding length of the push rod 9.

[0021] like Figure 3As shown, in some embodiments, the paper tube limiting assembly 15 includes a limiting disc 10, a limiting plate 11, a second support plate 12, a first support plate 13, a feeding channel 14, a feeding channel 16, and a roller 17, wherein: The first support plate 13 is fixedly installed above the conveyor belt baffle 3. The feeding channel 14 is fixed to the inner side of the first support plate 13. The feeding channel 14 is inclined relative to the conveyor belt baffle 3 towards the reciprocating propulsion assembly 20. Two second support plates 12 are respectively fixed to the sides of the two conveyor belt baffles 3. The inner sides of the two support plates 12 are fixed to the limiting plate 11. Bearing holes are opened on the two support plates 12. Bearings are fixed inside the bearing holes. The roller 17 is clearance-fitted between the two bearings. A gear 18 is fixed on the roller 17. The gear 18 meshes with the rack 902. A disc 10 is fixed on the shaft 17, and the roller 17 passes through the center of the disc 10. The disc 10 is located below the limiting plate 11. The limiting disc 10 has a V-shaped opening 1001 for receiving paper tubes. The disc 10 is tangent to the contact point with the feeding channel 14. One end of the feeding channel 16 is fixed to the two support plates 12, and the other end of the feeding channel is fixed to the two conveyor belt baffles 3. The feeding channel 16 is located below the feeding channel 14 and above the conveyor belt 2. The feeding channel 16 is inclined towards the drying equipment body 1 relative to the conveyor belt baffles 3.

[0022] The paper tube rolls towards the limiting plate 11 via the feeding channel 14. Under the combined action of the limiting plate 11 and the limiting disc 10, the paper tube is held in place and stabilized. When the V-shaped opening 1001 on the limiting disc 10 rotates to face the paper tube, the paper tube smoothly enters the V-shaped opening 1001. As the limiting disc 10 continues to rotate, the paper tube is conveyed to the feeding channel 16. Finally, the paper tube rolls from the feeding channel 16 onto the conveyor belt 2, completing the entire feeding process.
