[0018] Compared with the prior art, this application has the following beneficial effects:

[0019] The present application includes a frame, a drying box and a heating box are provided on the frame, a feed port is provided at one end of the drying box and a discharge port is provided at the other end thereof along the length direction of the drying box, and a recovery assembly for recovering the dried silicone tube is further provided on the frame; the inlet end of the heating box is connected to the drying box through a return pipe, and the outlet end of the heating box is connected to the drying box through a circulation pipe; a heating assembly is further provided in the heating box; a dehydration module is provided on the return pipe, and a circulation fan is provided on the circulation pipe; a wiping assembly is further provided in the drying box, and a controller is further provided on the frame, and the controller is electrically connected to the recovery assembly, the heating assembly and the circulation fan respectively;

[0020] When in use, the silicone tube cooled by the water cooling device enters the drying box from the feed port, extends from the discharge port after passing through the wiping component, and is finally connected to the recovery component.

At the same time, the heating box continuously generates hot air while establishing a hot air circulation between the heating box and the drying box to ensure the temperature inside the drying box.

[0021] Compared with the prior art, in the present application, before the silicone tube is dried, the silicone tube with a large number of water droplets attached to the surface will first contact the wiping component, and the water droplets attached to the surface of the silicone tube will be wiped and absorbed by the wiping component, thereby reducing the amount of water on the surface of the silicone tube as much as possible, and during the wiping process, the attached water gathered in the form of water droplets will diffuse into the surface, thereby increasing the contact area between the attached water and the hot air as much as possible; that is, the present application can not only reduce the amount of water attached to the surface of the silicone tube, but also increase the contact area between water and hot air, thereby optimizing the drying conditions from two aspects and improving the drying efficiency.

[0022] Secondly, since the technical solution described in the present application can diffuse the attached water into a planar shape, it not only increases the contact area with the hot air, but also effectively reduces the thickness of the water layer. Therefore, the heat can be transferred to all the water more quickly, which is conducive to lowering the temperature in the drying box. That is, while ensuring the drying effect, lowering the temperature in the drying box not only helps to reduce the energy consumption of the equipment, but also avoids the adverse effects of high temperature on the silicone tube, thereby ensuring the quality of the silicone tube.

[0023] Finally, since the wiping component is located as a whole in the drying box, the moisture adsorbed on the wiping component can be evaporated in time through the high temperature in the drying box, and discharged through the circulation of hot air and separated by the dehydration module, thereby ensuring that the accumulated water on the wiping component is within a controllable range, ensuring the continuous and stable operation of the equipment, and improving the operating efficiency of the equipment.

[0041] When in use, each silicone tube is respectively inserted into each clamping groove 24. Since the sponge has good adsorption and deformation ability, the sponge can wrap and fit the entire outer surface of the silicone tube, thereby comprehensively wiping the surface of the silicone tube;

[0042] Secondly, the wiping device has a simple structure, which reduces the hardware cost of the equipment and can achieve grooving operation on the surface of the silicone tube without additional operation, thus simplifying the operation process of the equipment;

After installation, the wiping sponge 23 and the auxiliary sponge 28 are in contact with each other.

[0044] The auxiliary sponge 28 can further wipe the top of the silicone tube to avoid water droplets remaining on the top of the silicone tube; at the same time, the limiting plate 26 can confine the silicone tube in the clamping groove 24 to avoid separation of the silicone tube from the clamping groove 24.

[0045] Furthermore, along the length direction of the limiting plate 26, one end of the limiting plate 26 is provided with a mounting hole, and the other end is provided with a U-shaped groove 27, and the open end of the U-shaped groove 27 faces either end of the limiting plate 26 in the width direction;

[0051] The PLC and the circulating fan 8 can also be electrically connected via a frequency converter to more accurately control the rotation speed of the circulating fan 8, thereby controlling the air supply volume;

[0052] Furthermore, a dehydration module is provided on the return pipe 6. The dehydration module includes a dehydration box 11. The dehydration box 11 is in the shape of a cuboid or a cube. An air inlet 12 is provided on one outer side of the dehydration box 11, and an air outlet 13 is provided on the other outer side.

[0057] Compared with the prior art, in the present application, before the silicone tube is dried, the silicone tube with a large number of water droplets attached to the surface will first contact the wiping component, and the water droplets attached to the surface of the silicone tube will be wiped and absorbed by the wiping component, thereby reducing the amount of water on the surface of the silicone tube as much as possible, and during the wiping process, the attached water gathered in the form of water droplets will diffuse into the surface, thereby increasing the contact area between the attached water and the hot air as much as possible; that is, the present application can not only reduce the amount of water attached to the surface of the silicone tube, but also increase the contact area between water and hot air, thereby optimizing the drying conditions from two aspects and improving the drying efficiency.

[0058] Secondly, since the technical solution described in the present application can diffuse the attached water into a planar shape, it not only increases the contact area with the hot air, but also effectively reduces the thickness of the water layer. Therefore, the heat can be transferred to all the water more quickly, which is conducive to lowering the temperature in the drying box. That is, while ensuring the drying effect, lowering the temperature in the drying box not only helps to reduce the energy consumption of the equipment, but also avoids the adverse effects of high temperature on the silicone tube, thereby ensuring the quality of the silicone tube.

[0059] Finally, since the wiping component is located as a whole in the drying box, the moisture adsorbed on the wiping component can be evaporated in time through the high temperature in the drying box, and discharged through the circulation of hot air and separated by the dehydration module, thereby ensuring that the accumulated water on the wiping component is within a controllable range, ensuring the continuous and stable operation of the equipment, and improving the operating efficiency of the equipment.
