[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a hot air circulation oven for the production of Chinese herbal medicine slices, which has the following beneficial effects:

[0018] (1) The utility model adopts a cam. When the hot air circulation oven for the production of Chinese herbal medicine slices is actually used, the hole box door is opened to insert four groups of drying frames with Chinese herbal medicine slices between two groups of support plates. The box door is closed, and the control panel is used to operate the fan, the electric heating wire and the servo motor. The fan drives the air to be heated by the electric heating wire. The heated air enters the interior of the dispersion plate and is evenly blown to the space between the two groups of support plates through the first vent hole. At the same time, the servo motor drives the shaft to rotate, and the shaft drives the two groups of cams to rotate.

This reciprocates to avoid the Chinese herbal medicine slices in the drying frame from contacting other parts for a long time. The cam is set to enable the Chinese herbal medicine slices to fully contact the heated air, thereby reducing the drying time and improving the practicality of the hot air circulation oven for the production of Chinese herbal medicine slices.

[0019] (2) The utility model adopts a crankshaft. According to the above operation, when the fan blows air, negative pressure is formed in the L-shaped tube and the two groups of ventilation pipes. The heated air passes through the four groups of drying frames to reach the bottom of the box body. The air reaching the bottom of the box body is mixed with water vapor. Under the action of the negative pressure in the L-shaped tube and the two groups of ventilation pipes, the air reaching the bottom of the box body enters the dehydration tank along the connecting pipe, passes through the two groups of second sponges installed inside and re-enters the two groups of ventilation pipes. The moisture in the air is sucked into the two groups of sponge blocks. When the two groups of sponge blocks absorb too much water, the reduction motor is started, and the reduction motor drives the crankshaft to rotate. The crankshaft drives the two groups to swing. The two groups of connecting rods respectively drive the two groups of first sliders to alternately squeeze the sponge blocks, so that the moisture in the sponge blocks can be squeezed into the dehydration tank through the second ventilation holes. Through the set crankshaft, the air can be dried without affecting the air circulation, so that the heated air can be recycled, thereby reducing the energy consumption of the hot air circulation oven used for the production of Chinese herbal medicine slices.

[0035] Working principle:

[0036] When the hot air circulation oven for the production of Chinese herbal medicine slices is actually used, the oven door 24 is opened and the four drying frames 3 with the Chinese herbal medicine slices are inserted between the two groups of support plates 2. The oven door 24 is closed, and the fan, the electric heating wire 12 and the servo motor 13 are operated by using the control panel. The fan drives the air to be heated by the electric heating wire 12. The heated air enters the dispersion plate 8 and is evenly blown to the space between the two groups of support plates 2 through the first vent 9. At the same time, the servo motor 13 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the two groups of cams 21 to rotate. The two groups of cams 21 contact with the right group of support plates 2, thereby pushing the left group of support plates 2 to compress the two groups of springs 5. The two groups of cams 21 continue to rotate, and the cams 21 no longer squeeze the right group of support plates 2. The two groups of springs 5 ​​are reset, driving the left group of support plates 2 to reset, and so on. This prevents the Chinese herbal medicine slices in the drying frame 3 from contacting other parts for a long time. The cam 21 is set, so that the Chinese herbal medicine slices can be fully contacted with the heated air, which reduces the drying time and improves the practical use of the hot air circulation oven for the production of Chinese herbal medicine slices. According to the above operation, when the fan blows, negative pressure is formed in the L-shaped tube 14 and the two sets of ventilation pipes 15, and the heated air passes through the four sets of drying frames to reach the bottom of the box body 1. The air reaching the bottom of the box body 1 is mixed with water vapor. Under the action of the negative pressure in the L-shaped tube 14 and the two sets of ventilation pipes 15, the air reaching the bottom of the box body 1 enters the dehydration tank 27 along the connecting pipe 19, passes through the two sets of sponges installed inside the second installation, and re-enters the two sets of ventilation pipes 15. The moisture in the air is sucked into the two sets of sponge blocks 33. The two sets of sponge blocks 33 are When too much water is absorbed, the reduction motor 16 is started, the reduction motor 16 drives the crankshaft 17 to rotate, the crankshaft 17 drives the two groups to swing, and the two groups of connecting rods 31 respectively drive the two groups of first sliders 30 to alternately squeeze the sponge block 33, so that the water in the sponge block 33 can be squeezed into the dewatering tank 27 through the second vent hole 34. Through the crankshaft 17, the air can be dried without affecting the air circulation, so that the heated air can be recycled, thereby reducing the energy consumption of the hot air circulation oven for the production of Chinese herbal medicine slices.
