[0038] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0039] Referring to Figure 2 、 Figure 3 and Figure 4 As shown in, an embodiment provided by the present invention: A pigment drying device includes a heat preservation shell 1. The inner bottom wall of the heat preservation shell 1 is fixedly connected with a heating oven 3. A plurality of heating rods 4 are fixedly connected at equal intervals around the inner wall of the heat preservation shell 1. A plurality of air inlet holes 5 are equidistantly opened on the outer wall of the heating oven 3. A conical plate 6 is fixedly connected to the middle and lower part of the inner wall of the heating oven 3. A fan 7 is fixedly connected to the middle of the conical plate 6. A U-shaped plate 8 is fixedly connected to the middle of the inner wall of the heating oven 3. A plurality of air outlet holes 9 are opened on the top wall of the U-shaped plate 8. A pigment drying tank 10 is slidably connected to the inner wall of the air outlet hole 9. The left side of the top wall of the heat preservation shell 1 is communicated with a conical pipe 11. The top wall of the conical pipe 11 is communicated with an exhaust valve 12. A telescopic stirring mechanism 2 is arranged at the rear side of the inner wall of the heating oven 3;

[0040] Specifically, the heating oven 3 generates heat through the heating rods 4 around the inner wall, heats the air in the heat preservation shell 1, and creates a high-temperature drying environment. The plurality of air inlet holes 5 on the outer wall of the heating oven 3 enable the heated air to be transported to the inside of the heating oven 3 under the action of the fan 7, which can more effectively remove the moisture of the pigment. Since the fan 7 is located in the middle of the conical plate 6, the hot air will be guided outside the air outlet holes 9 opened on the U-shaped plate 8 and evenly blown to the pigment drying tank 10 through the air outlet holes 9. The U-shaped plate 8 makes the flow of the hot air more uniform, avoiding the direct blowing of the hot air on the pigment, resulting in local overheating and uneven drying. During the drying process, the moisture in the pigment is evaporated and discharged through the exhaust valve 12 connected to the conical pipe 11, effectively maintaining the dry environment in the heating oven 3. The pigment drying tank 10 slides in front of the U-shaped plate 8, the heating oven 3 and the heat preservation shell 1, facilitating the replacement of the next wave of undried pigment. Through the efficient and uniform hot air circulation, the rapid drying of the pigment is realized.

[0041] Referring to Figure 1 、 Figure 4 and Figure 5, the telescopic stirring mechanism 2 includes a pressure sensor 201. In the middle of the top wall of the heat preservation shell 1, a low-frequency rotating motor 202 is fixedly connected. The output end of the low-frequency rotating motor 202 is fixedly connected with a driving shaft 203. At the bottom end of the outer wall of the driving shaft 203, a stirring paddle 204 is fixedly connected. On the inner top wall of the heat preservation shell 1, a limiting cylinder 205 is fixedly connected. In the middle and upper part of the outer wall of the driving shaft 203, a limiting turntable 206 is fixedly connected. The limiting turntable 206 is slidably connected to the inner wall of the limiting cylinder 205. On the top wall of the heat preservation shell 1, a telescopic fixed cylinder 207 is fixedly connected. Around the outer wall of the telescopic fixed cylinder 207, moving grooves 208 are equidistantly arranged. At the four corners of the bottom wall of the low-frequency rotating motor 202, moving support rods 209 are fixedly connected. The plurality of moving support rods 209 are all slidably connected in the plurality of moving grooves 208;

[0042] Specifically, the pressure sensor 201 can come into contact with and sense the pressure sensor 201 after the pigment drying tank 10 is completely pushed into the U-shaped plate 8, and at the same time activate the opening function of the low-frequency rotating motor 202. Since the plurality of moving support rods 209 fixed to the bottom wall of the low-frequency rotating motor 202 are slidably connected to the moving grooves 208 opened on the outer wall of the telescopic fixed cylinder 207, the low-frequency rotating motor 202 can be lifted upward, rotated clockwise and then moved downward to the bottommost position for clamping. In this way, the stirring paddle 204 at the bottom end of the low-frequency rotating motor 202 can be moved into the pigment drying tank 10. At the same time, during the rotation of the low-frequency rotating motor 202, the limiting turntable 206 is fixedly connected to the driving shaft 203, and the limiting turntable 206 will rotate in the limiting cylinder 205 along with the driving shaft 203, which can ensure the stability during stirring. The height of the moving groove 208 is less than the movable height in the limiting cylinder 205, so as to avoid the influence of the low-frequency rotating motor 202 on the limiting cylinder 205 during the up and down movement, realizing the full stirring of the pigment and enabling the water to evaporate more evenly during the drying process.

[0043] Refer to Figure 2 , on the front side of the pigment drying tank 10 and the top end of the low-frequency rotating motor 202, handles 13 are fixedly connected. On the outer walls of the plurality of handles 13, rubber sleeves 14 are fixedly connected; on the front side of the top wall of the heat preservation shell 1, a control console 15 is fixedly connected. On the top wall of the control console 15, a plurality of control buttons 16 are fixedly installed; on the front side top end of the heat preservation shell 1, a thermometer 17 is fixedly connected. The thermometer 17 is electrically connected to the heating rod 4;

[0044] Specifically, the handle 13 at the top of the low-frequency rotating motor 202 on the front side of the pigment drying tank 10 facilitates the operator to lift and move the pigment drying tank 10 and the low-frequency rotating motor 202. The rubber sleeve 14 on its outer wall can provide a good grip and prevent the hand from getting heated. The control console 15 serves as the operation center of the entire device. The multiple control buttons 16 on its top can adjust the low-frequency rotating motor 202, the heating rod 4, and the fan 7. The thermometer 17 on the front side of the heat preservation shell 1 can display the temperature inside the heat preservation shell 1 in real time, helping the operator accurately control the drying conditions and ensuring the quality of pigment drying.

[0045] Refer to Figure 1 , Figure 3 and Figure 4 , both the front and rear sides of the inner wall of the heating oven 3 are fixedly connected with two support crossbars 18. The two support crossbars 18 are at the same height and parallel to each other; at the four corners of the bottom wall of the heat preservation shell 1, there are fixedly connected with columns 19. The bottom ends of the multiple columns 19 are all fixedly connected with anti-slip pads 20; the front width of the pigment drying tank 10 is equal to the front inner wall width of the heat preservation shell 1, and the front height of the pigment drying tank 10 is equal to the front inner wall height of the heat preservation shell 1. The outer wall of the pigment drying tank 10 is slidably connected with the front inner wall of the heat preservation shell 1;

[0046] Specifically, the support crossbars 18 are used to support the whole pigment drying tank 10. The two support crossbars 18 being at the same height and parallel to each other is to ensure that the pigment drying tank 10 will not shake during the heating process, providing a horizontal support surface for the pigment drying tank 10. The columns 19 play a supporting role for the whole device, evenly dispersing the weight of the device to the ground. The anti-slip pads 20 at their bottom ends increase the friction between the device and the ground, ensuring the use safety. The pigment drying tank 10 is slidably connected with the inner wall of the heat preservation shell 1, which is convenient for putting in and taking out the pigment, and at the same time can be closely matched to reduce heat loss and ensure the drying effect of the pigment.

[0047] Working principle: The heating oven 3 generates heat through the heating rods 4 around its inner wall, heating the air inside the heat preservation shell 1 to create a high-temperature drying environment. The multiple air inlet holes 5 on the outer wall of the heating oven 3 enable the heated air to be transported to the inside of the heating oven 3 under the action of the fan 7, which can more effectively remove the moisture of the pigment. Since the fan 7 is located in the middle of the conical plate 6, the hot air will be guided outside the air outlet holes 9 opened on the U-shaped plate 8 and evenly blown onto the pigment drying tank 10 through the air outlet holes 9. The U-shaped plate 8 makes the flow of the hot air more uniform, avoiding the direct blowing of the hot air on the pigment, causing local overheating and uneven drying. During the drying process, the moisture in the pigment is evaporated and discharged through the exhaust valve 12 connected to the conical pipe 11, effectively maintaining the dry environment inside the heating oven 3. The pigment drying tank 10 slides in front of the U-shaped plate 8, the heating oven 3, and the heat preservation shell 1, which is convenient for replacing the next wave of undried pigment;

[0048] Moreover, the pressure sensor 201 can come into contact with and sense the pressure sensor 201 after the pigment drying tank 10 is completely pushed into the U-shaped plate 8, and at the same time activate the opening function of the low-frequency rotation motor 202. Since a plurality of moving support rods 209 fixed to the bottom wall of the low-frequency rotation motor 202 are slidably connected to the moving grooves 208 formed on the outer wall of the telescopic fixed cylinder 207, the low-frequency rotation motor 202 can be lifted upward, rotated clockwise and then moved downward to the bottommost position for engagement, so that the stirring paddle plate 204 at the bottom end of the low-frequency rotation motor 202 can be moved into the pigment drying tank 10. At the same time, during the rotation of the low-frequency rotation motor 202, the limiting turntable 206 is fixedly connected to the drive shaft 203, and the limiting turntable 206 will rotate in the limiting cylinder 205 along with the drive shaft 203, which can ensure the stability during stirring. The height of the moving groove 208 is less than the height that can be moved in the limiting cylinder 205, so as to prevent the low-frequency rotation motor 202 from affecting the limiting cylinder 205 during the up-and-down movement.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
