[0044] The top of the sliding plate 4707 is fixedly connected with a second spring 4705, the upper end of the second spring 4705 is fixedly connected with the bottom of the mounting shell 4701, the surface of the sliding plate 4707 is fixedly connected with a trigger rod 4708, the other end of the trigger rod 4708 penetrates out of the connecting shell 4706, and the trigger rod 4708 can be contacted by the rotating process of the rotating lever 460.

[0045] The adsorption plate 4703 is an iron metal material member, and can also be formed of other materials capable of being adsorbed after the electromagnet 4702 generates a magnetic force, which is not specifically limited here.

[0046] Under normal circumstances, the bottom of the sliding plate 4707 can be brought into close contact with the bottom of the connecting shell 4706 under the action of the second spring 4705, as shown in the accompanying Figure 4 At this time, the trigger rod 4708 can be pushed to rotate by the rotating lever 460 under the rotating action of the rotating disc 450, thereby driving the connecting shell 4706 and the mounting shell 4701 to rotate the placing table 470, so as to drive the tin paste tank placed above the placing table 470 to rotate, so that the tin paste can be uniformly warmed up when the heated air flow passes through.

[0047] The adsorption plate 4703 can be adsorbed by starting the electromagnet 4702, that is, the adjusting column 4704 can be driven to move up synchronously, which can drive the sliding plate 4707 to press the second spring 4705 and drive the trigger rod 4708 to move up synchronously in the process, so that the rotating lever 460 cannot contact the trigger rod 4708 in the rotating process in this state, so as not to drive the placing table 470 to rotate, thereby facilitating the staff to take the tin paste tank.

[0048] As shown in Figures 1-5As shown, the driving assembly 400 further comprises a connecting block 490 fixedly connected to the top of the body 100, the surface of the connecting block 490 is provided with a clamping groove 4902, the inside of the connecting block 490 is provided with an adjusting cavity 4901, the inner wall of the adjusting cavity 4901 is slidably connected with a sliding plate 4904, and the sliding plate 4904 is fixedly connected with a third spring 4905 on one side and the inner wall of the adjusting cavity 4901.

[0052] As shown in the accompanying drawings, Figure 6 and Figure 7As shown, the auxiliary assembly 300 includes a connecting hole 310 opened on the surface of the body 100 and communicated with the adjacent placing groove 120, the inner wall of the connecting hole 310 is provided with a mounting cavity 320, and the inside of the body 100 is provided with two collecting cavities 330 located below the two heat dissipation cavities 130 respectively.

[0053] The inside of the mounting cavity 320 is provided with a mounting plate 3201, the surface of the mounting plate 3201 is fixedly connected with a mounting block 3202 fixedly connected with the inner wall of the mounting cavity 320, one side of the mounting plate 3201 close to the placing groove 120 is fixedly connected with a mounting column 3204, the surface of the mounting column 3204 is slidably connected with a sealing ring 3207, the outer side of the sealing ring 3207 is in contact with the inner wall of the mounting cavity 320, and the surface of the mounting column 3204 is provided with a through groove 3205, and the surface of the sealing ring 3207 and the inner wall of the mounting plate 3201 are fixedly connected with a first spring 3206.

[0054] The inner wall of the through groove 3205 is fixedly connected with uniformly distributed partition plates 3203, the inner wall of the through groove 3205 is fixedly connected with four groups of pipes 3208 distributed alternately, the included angle between the pipe 3208 and the partition plate 3203 is ninety degrees, the pipe 3208 penetrates through a plurality of partition plates 3203 in sequence and is fixedly connected with the inner wall of the through groove 3205, and the upper surface of the pipe 3208 is provided with uniformly distributed collecting holes 3209.

[0055] The two adjacent pipes 3208 are communicated with uniformly distributed mounting pipes, the bottom of one of the pipes 3208 is communicated with uniformly distributed discharge pipes 3210, and the other end of the discharge pipe 3210 penetrates through the body 100 and the heat dissipation cavity 130 in sequence and is communicated with the collecting cavity 330.

[0056] The tin paste tank is usually stored in the refrigerator for refrigeration, and water mist or frost is easily formed on the surface of the tin paste tank during the refrigeration process. During the warming process, the water will slowly drip as the temperature increases, because the temperature is not very high during the warming process, and the water cannot form water vapor. As the number of tin paste tanks increases, more water will accumulate in the placing groove 120. Although part of the water can be discharged through the exhaust pipe in the traditional warm air warming method, part of the water will drip back into the placing groove 120 after stopping heating, or stay in the pipe for a long time, which will cause damage to the device.

[0057] The water formed during the heating process of the device can be gradually brought into the inside of the connecting hole 310 under the action of the airflow, and as the heating progresses, the gas inside the placement groove 120 gradually increases, which can increase the air pressure inside the placement groove 120 to overcome the elastic force of the first spring 3206 to drive the sealing ring 3207 to slide along the surface of the mounting column 3204, until the position of the through slot 3205 is moved to the middle, at this time the airflow and moisture can enter between the baffles 3203 and enter the inside of the conduit 3208 through the collection hole 3209, and then be discharged through the collection hole 3209 on the other side of the sealing ring 3207. In this process, the water adheres to the inner wall of the conduit 3208 in a large area and is finally discharged through the discharge pipe 3210, and because the discharge pipe 3210 is partially located inside the heat dissipation cavity 130, it can be fully cooled. Because the temperature of the discharged airflow is higher than that of the discharge pipe 3210 and the conduit 3208, a temperature difference is formed, which can better collect moisture and guide it into the collection cavity 330 to facilitate unified cleaning.

[0058] Working principle: the tin paste that needs to be rewarmed is placed on the placement platform 470 inside the placement groove 120, then the cover plate 110 is closed, and the fan 140 and the electric heating pipe 160 are started to form a heated airflow into the inside of the placement groove 120 to reheat the tin paste. By starting the motor 410, the first sprocket, the first chain 420 and the second sprocket can be driven to rotate under the action of the first chain 420, which can drive the remaining rotating wheels 440 to rotate synchronously under the joint action of the second chain 430 and the third sprocket, thereby reducing the use cost. Under the rotating action of the rotating wheel 440, the rotating disc 450 and the lever 460 connected thereto can be driven to rotate synchronously, and under the rotating action of the rotating disc 450, the trigger rod 4708 can be pushed to rotate through the lever 460, thereby driving the connecting shell 4706 and the mounting shell 4701 to rotate the placement platform 470 to rotate the tin paste tank placed above the placement platform 470. The heated airflow can uniformly reheat it, until the preset reheat time is reached, the electromagnet 4702 is energized to adsorb the adsorption plate 4703, which can drive the adjustment column 4704 to move up synchronously, which can drive the sliding plate 4707 to extrude the second spring 4705 and drive the trigger rod 4708 to move up synchronously. In this state, the lever 460 cannot contact the trigger rod 4708 during rotation, so the placement platform 470 will not rotate, which facilitates the staff to take the tin paste tank and remove the limit of the protrusion to open the cover plate 110.

[0059] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as there is no conflict, any combination of the technical features should be considered within the scope of the present disclosure.
