Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulating tube drying technology, specifically a drying device for insulating tube production. Background Technology
[0002] Insulating tubes are electrical insulating tubes made by coating alkali-free glass fiber tubes with modified polyvinyl chloride resin and then plasticizing them. They have excellent flexibility and elasticity, as well as good dielectric properties and chemical resistance, and are suitable for wiring insulation and mechanical protection of motors, electrical appliances, instruments, radio and other devices.
[0003] During the processing of insulating tubes, modified polyvinyl chloride resin is sprayed onto the surface of the insulating tubes. Therefore, the insulating tubes need to be dried after spraying. In the existing technology, the insulating tubes are generally placed directly inside the drying device. However, since the insulating tubes are placed statically in the drying device, the coating material on the surface of the insulating tubes will flow under the action of gravity, resulting in uneven distribution of the coating material on the surface of the insulating tubes and affecting the drying quality of the insulating tubes. At the same time, since the insulating tubes are stationary, there will be uneven drying between the insulating tubes near the drying hot air blower and the insulating tubes far away from the hot air blower.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a drying device for producing insulating tubes includes a drying chamber 1. Heating fans 2 are fixedly installed on both sides of the drying chamber 1, and the air outlets of the heating fans 2 are connected to the interior of the drying chamber 1. A turntable 3 is rotatably installed inside the bottom of the drying chamber 1. Mounting plates 4 are symmetrically fixedly installed on both sides of the turntable 3. A rotating shaft 5 is rotatably installed in the middle of the mounting plate 4 via bearings at equal intervals. A movable locking rod 6 is elastically installed at one end of the rotating shaft 5 on one of the mounting plates 4. An insulating tube is installed between the movable locking rod 6 and the rotating shaft 5 on the other mounting plate 4. The two ends of the insulating tube are moved and inserted outside one end of the movable locking rod 6. Between the outer side of one end of the rotating shaft 5 on another mounting plate 4, the door of the drying chamber 1 is closed, and the heating fan 2 is controlled to operate, so that hot air is introduced into the drying chamber 1 to dry the insulating tube. During the drying process, the rotating disc 3 is controlled to rotate, which can drive the insulating tube between the two mounting plates 4 to rotate. The air outlet position of the insulating tube and the heating fan 2 can be adjusted at any time to control the uniform heating of the entire insulating tube. At the same time, during the rotation of the rotating disc 3, several rotating shafts 5 can be driven to rotate simultaneously, which can drive the insulating tube to rotate along its own central axis at all times. This can control the coating on the outside of the insulating tube to be evenly applied to the surface of the insulating tube, thereby improving the drying quality of the insulating tube.
[0022] like Figures 1 to 4 As shown, a base 7 is fixedly installed on the inner wall of the bottom end of the drying oven 1, and a rotating motor 8 is fixedly installed in the middle of the bottom end of the base 7. The output end of the rotating motor 8 passes through the base 7 and is fixedly connected to the middle of the turntable 3.
[0023] By rotating the motor 8 to drive the turntable 3 to rotate, the insulating tube located between the two mounting plates 4 can be rotated.
[0024] like Figures 1 to 4 As shown, a limiting rod 9 is symmetrically fixedly installed at one end of the movable locking rod 6, and a limiting hole 10 is symmetrically opened at one end of the rotating shaft 5 on which the movable locking rod 6 is installed. The limiting hole 10 is slidably connected to the limiting rod 9. A spring 11 is sleeved on the outer side of the end of the limiting rod 9 near the movable locking rod 6. One end of the spring 11 is fixedly connected to the movable locking rod 6, and the other end of the spring 11 is fixedly connected to the rotating shaft 5.
[0025] Push the movable lever 6 on the rotating shaft 5 closer to the rotating shaft 5, and control the limiting rod 9 to slide inside the limiting hole 10. At this time, the spring 11 is in a compressed state, and moves both ends of the insulating tube to be inserted on the outside of one end of the movable lever 6 and the outside of one end of the rotating shaft 5 on the other mounting plate 4. The spring 11 pushes the movable lever 6 to control the insulating tube to be fixed between the movable lever 6 and one end of the rotating shaft 5 on the other mounting plate 4, which facilitates the fixing of the position of the insulating tube.
[0026] like Figures 1 to 4 As shown, a bevel gear 12 is fixedly installed at one end of the topmost rotating shaft 5 on one of the mounting plates 4. A bevel gear ring 13 is fixedly installed on the inner wall of the top of the drying box 1. The bevel gear ring 13 meshes with the bevel gear 12. A first gear 14 is fixedly installed at one end of several rotating shafts 5 on the mounting plate 4 on which the bevel gear 12 is installed. A second gear 15 is rotatably installed on one side of the mounting plate 4 on which the bevel gear 12 is installed via a shaft pin. The first gear 14 meshes with the second gear 15.
[0027] During the rotation of the turntable 3, the bevel gear 12 on the topmost rotating shaft 5 of one of the mounting plates 4 is constantly engaged with the bevel gear ring 13 on the inner wall of the top of the drying box 1, which will drive the rotating shaft 5 with the bevel gear 12 to rotate constantly. The first gear 14 and the second gear 15 at one end of several rotating shafts 5 are engaged at intervals to drive several rotating shafts 5 to rotate simultaneously.
[0028] like Figures 1 to 4 As shown, inside the drying chamber 1, guide vanes 16 are equidistantly mounted at the air outlet position of the heating fan 2 via shaft pins. A connecting rope 17 is fixedly installed between the middle of one end of several guide vanes 16. A winding motor 18 is fixedly installed on both sides of the drying chamber 1. A winding wheel 19 is fixedly installed through the drying chamber 1 at the output end of the winding motor 18. The winding wheel 19 is used to wind up the connecting rope 17. A lead weight 20 is fixedly installed at the bottom end of the connecting rope 17.
[0029] During the drying operation, the connecting rope 17 is intermittently wound up by the winding motor 18, and the weight of the connecting rope 17 is increased by the plumb bob 20. This intermittently drives the air guide vane 16 to rotate. The rotation of the air guide vane 16 can intermittently change the air outlet direction of the heating fan 2, further improving the uniform heating effect on the entire insulating tube.
[0030] This utility model provides a drying device for the production of insulating tubes, the specific working principle of which is as follows:
[0031] When using the device, push the movable locking rod 6 on the rotating shaft 5 closer to the rotating shaft 5, and control the limiting rod 9 to slide inside the limiting hole 10. At this time, the spring 11 is in a compressed state, moving both ends of the insulating tube to be inserted into the outer side of one end of the movable locking rod 6 and the outer side of one end of the rotating shaft 5 on the other mounting plate 4. The spring 11 pushes the movable locking rod 6 to control the insulating tube to be fixed between the movable locking rod 6 and one end of the rotating shaft 5 on the other mounting plate 4, which is used to fix the position of the insulating tube. Then close the door of the drying chamber 1, control the heating fan 2 to operate, and introduce hot air into the drying chamber 1 to dry the insulating tube. During the drying process, the rotating motor 8 drives the turntable 3 to rotate, which can drive the two fixed rods to be inserted into the turntable 10. The rotating insulating tube between the mounting plates 4 allows for constant adjustment of the air outlet position of the insulating tube and the heating fan 2, controlling the uniform heating of the entire insulating tube. Simultaneously, during the rotation of the turntable 3, the bevel gear 12 on the topmost rotating shaft 5 of one of the mounting plates 4 meshes with the bevel gear ring 13 on the inner wall of the top of the drying chamber 1, driving the rotating shaft 5 equipped with the bevel gear 12 to rotate continuously. Furthermore, the meshing of the first gear 14 and the second gear 15 at one end of several rotating shafts 5 drives several rotating shafts 5 to rotate simultaneously, thereby causing the insulating tube to rotate continuously along its central axis. This allows for control of the coating on the outer side of the insulating tube to be evenly applied to the surface of the insulating tube, improving the drying quality of the insulating tube.
