[0023] The following will describe in detail a kind of A provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative ways for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0024] As Figure 1 - Figure 4 shown, an embodiment of the present utility model provides a drying machine for finished sheathing materials, including a heat insulation cover 1. Hot air blowers 2 are fixedly installed on both sides of the heat insulation cover 1. The output end of the hot air blower 2 is fixedly connected to an air inlet pipe 3. A blowing pipe 4 is fixedly installed on the air inlet pipe 3. A moving block 5 is arranged on one side of the blowing pipe 4. A turning rod 6 is fixedly connected to the lower side of the moving block 5. A material box 7 is arranged under the turning rod 6. A heat preservation cover 8 is installed outside the material box 7.

[0025] Connect the feeding pipe 12 to the output end of the granulator so that the material falls into the material box 7. By starting the hot air blower 2, the hot air blown out by the hot air blower 2 enters the air inlet pipe 3, and then the hot air is blown out through the blowing pipes 4 arranged in a linear array on the air inlet pipe 3, so as to blow the hot air into the material box 7, thereby drying the material. A plurality of blowing pipes 4 are provided, which increases the drying area and improves the drying effect. Then, the movement of the moving block 5 drives the turning rod 6 to move in the material box 7, thereby turning the material. While avoiding material caking, it also improves the contact rate between the hot air and the sheathing material, and improves the drying efficiency.

[0026] As Figure 1 - Figure 3As shown in the figure, a vent pipe 9 is fixedly sleeved on the top of the heat insulation cover 1. A filter plate 10 is fixedly installed inside the vent pipe 9. A desiccant box 11 is fixedly installed on the inner wall of the top of the heat insulation cover 1. The top of the heat insulation cover 1 is communicated with the vent pipe 9, so that the excessive pressure in the inner cavities of the heat insulation cover 1 and the heat preservation cover 8 can be avoided through the vent pipe 9. The lower surface of the heat insulation cover 1 is fixedly connected with the heat preservation cover 8. The material box 7 is fixedly installed in the heat preservation cover 8. The feeding pipe 12 is fixedly sleeved on one side of the heat preservation cover 8 and the material box 7, which is convenient for adding materials. The air inlet pipe 3 is fixedly sleeved inside the heat insulation cover 1. The electric heating pipe 13 is fixedly connected to the inner wall of the heat preservation cover 8. A sealing cover 14 is sleeved at the bottom of the material box 7. The sealing cover 14 is fixedly connected with the heat preservation cover 8 through bolts. The electric heating pipe 13 is fixedly connected to the inner wall of the heat preservation cover 8. By means of the electric heating pipe 13, it is beneficial to increase the temperature inside the material box 7, thereby improving the drying efficiency. Air holes with a diameter smaller than the sheath material are formed on the side of the material box 7, which is convenient for the hot air to enter, while the material will not leak out.

[0027] Dock the feeding pipe 12 with the output end of the granulator, so that the sheath material directly enters the material box 7 from the feeding pipe 12. After the material addition is completed, cover the feeding pipe 12 with a cover plate. At this time, start the hot air blower 2, so that the hot air blown out by the hot air blower 2 enters the air inlet pipe 3 and is blown out from several air blowing pipes 4 installed on the air inlet pipe 3, so that the hot air blows towards the material box 7, thereby drying the sheath material. At the same time, by heating the electric heating pipe 13, the hot air enters the material box 7 through the round holes formed on the surface of the material box 7, thereby further drying the sheath material, thus improving the drying efficiency and drying effect. The heat insulation cover 1 can prevent the hot air blower 2 and the motor 16 from being damaged. The vent pipe 9 communicated with the top of the heat insulation cover 1 can prevent the excessive pressure inside the heat insulation cover 1 and the heat preservation cover 8, ensuring safety. A desiccant is stored in the desiccant box 11 fixedly installed on the inner top of the heat insulation cover 1. The desiccant can effectively absorb water vapor, keep the overall equipment dry and prevent the sheath material from being affected by moisture again.

[0028] As Figure 3 - Figure 4 As shown in the figure, a threaded rod 15 is threadedly sleeved inside the moving block 5. One end of the threaded rod 15 is rotatably sleeved inside the heat insulation cover 1, and the other end of the threaded rod 15 penetrates through the heat insulation cover 1 and is fixedly connected to the output end of the motor 16. The motor 16 is fixedly installed on one side of the heat insulation cover 1. The motor 16 drives the threaded rod 15 to rotate inside the heat insulation cover 1, so that the threaded rod 15 drives the moving block 5 to move on the threaded rod 15. Limiting grooves 17 are formed on both sides of the inner wall of the heat insulation cover 1. One end of the limiting rod 18 is slidably connected with the limiting groove 17, and the other end of the limiting rod 18 is fixedly connected with the moving block 5. The turning rod 6 is slidably connected with the material box 7. The limiting grooves 17 formed on both sides of the inner wall of the heat insulation cover 1 limit the limiting rod 18, thereby improving the stability of the movement of the moving block 5.

[0029] By starting the motor 16, the motor 16 drives the threaded rod 15 to rotate. Under the rotation of the threaded rod 15, the threaded rod 15 drives the moving block 5 to move. The moving block 5 drives the turning rod 6 to move through the sliding fit between the limiting rod 18 and the limiting groove 17. By controlling the forward and reverse rotation of the motor 16, the moving block 5 is enabled to drive the turning rod 6 to reciprocate horizontally in the material box 7, thereby increasing the contact rate between the hot air and the sheath material, and further improving the drying efficiency and drying effect.

[0030] In the actual use of the technical solution provided by the present utility model, the hot air blower 2, the electric heating pipe 13, and the motor 16 are all electrically connected to an external terminal control device. The feed pipe 12 is docked with the output end of the granulator, so that the sheath material directly enters the material box 7 from the feed pipe 12. After the material addition is completed, a cover plate is placed on the feed pipe 12. At this time, by starting the hot air blower 2, the hot air blown out by the hot air blower 2 enters the air inlet pipe 3 and is blown out from a plurality of air blowing pipes 4 installed on the air inlet pipe 3, so that the hot air blows towards the material box 7 to dry the sheath material. At the same time, by heating the electric heating pipe 13, the hot air enters the material box 7 through the circular holes opened on the surface of the material box 7, so as to further dry the sheath material, thereby improving the drying efficiency and drying effect. Then, by starting the motor 16, the motor 16 drives the threaded rod 15 to rotate. Under the rotation of the threaded rod 15, the threaded rod 15 drives the moving block 5 to move. The moving block 5 drives the turning rod 6 to move through the sliding fit between the limiting rod 18 and the limiting groove 17. By controlling the forward and reverse rotation of the motor 16, the moving block 5 is enabled to drive the turning rod 6 to reciprocate horizontally in the material box 7, thereby increasing the contact rate between the hot air and the sheath material, and further improving the drying efficiency and drying effect. After the sheath material is dried, the material is taken out by removing the sealing cover 14.
