Description

Technical Field

[0001] The invention relates to the field of drying equipment, in particular to an air energy heat pump drying machine. Background Art

[0002] Air energy heat pump dryer is a new type of drying device. Air energy heat pump dryer is often used in the field of drying clothes, food, and Chinese medicinal materials. The air energy heat pump transports dry hot air into the drying box. The dry hot air circulates in the drying box, which can dry the materials inside it. When using an air energy heat pump dryer to bake products such as dried meat, the meat slices are usually placed on a mesh disk, and then the mesh disk is placed in the drying box of the air energy heat pump dryer. Because the meat slices are soft before drying, they can adhere closely to the grid lines in the mesh disk. During the drying process, the meat slices gradually lose moisture, become dry and hard, and become sticky to the grid lines. As a result, when the dried meat needs to be taken out after each baking, it cannot be directly poured off the mesh disk, and it is necessary to move the dried meat one by one to separate it from the mesh disk. If the products being baked are dried fruits, Chinese medicinal materials, etc. with a high sugar content, the sugar in these products will stick to the grid lines in the mesh disk when it is baked out, which will also affect the collection of the baked products, resulting in the product not being able to be directly poured off the mesh disk, affecting the overall collection efficiency.

[0019] The facing end surfaces of the two rack support plates 3 in the same group are fixedly provided with limit blocks 4, and the limit blocks 4 are distributed on the side of the rack support plate 3 away from the box door 2. The end of the limit blocks 4 facing the box door 2 is tilted, and the skirt 6 is slidably inserted between the limit blocks 4 and the rack support plates 3. The tilted limit blocks 4 can guide the skirt 6, so that the skirt 6 can be more smoothly inserted between the limit blocks 4 and the rack support plates 3.

[0020] The scraping unit includes two transverse grooves 7 opened on the left and right side walls of each mesh plate 5, the transverse grooves 7 are located on the upper end surface of the inner bottom surface of the mesh plate 5, and a toggle rod 8 is slidably inserted between the two transverse grooves 7. The bottom sliding sleeve of the mesh plate 5 is provided with a limit frame 9, and both ends of the limit frame 9 are rotatably sleeved on the outer surface of the toggle rod 8. The two ends of the toggle rod 8 are also fixedly sleeved with a first gear 10, and the limit frame 9 is located between the two first gears 10. A rack 11 is placed horizontally above each first gear 10, and a matching component is provided between the several racks 11 located on the same side and the drying box 1. When the rack 11 descends and contacts the first gear 10, the two can engage with each other.

[0021] The mating parts include connecting blocks 12 fixedly arranged at both ends of each rack 11, and each connecting block 12 is fixedly inserted with a column 13 at one end away from the mesh plate 5, and the left and right side walls inside the drying box 1 are slidably equipped with a lifting plate 17, and each column 13 on the same side is fixed on the same lifting plate 17 at one end away from the connecting block 12, and a connecting rod 18 is fixedly inserted inside each lifting plate 17, and the upper end of the connecting rod 18 slides through the drying box 1, and a toggle plate 20 is fixedly arranged at the exposed ends of the two connecting rods 18, and a tension spring 19 is slidably sleeved on the outer surfaces of the two connecting rods 18, and the two ends of the tension spring 19 are respectively fixed between the top of the drying box 1 and the bottom of the toggle plate 20, and the tension spring 19 can apply downward elastic pressure to the two lifting plates 17 through the toggle plate 20 and the connecting rod 18, so that the first gear 10 and the rack 11 can be tightly meshed.

[0022] The driving unit includes an optical axis 15 fixedly mounted on the upper and lower ends of each lifting plate 17. The optical axis 15 is parallel to the rack 11 and is located between the rack 11 and the lifting plate 17. The outer surfaces of the two optical axes 15 on the same side are slidably sleeved with a slide plate 14. A plurality of right-angle blocks 16 equidistantly distributed in a straight line are fixedly provided on one end surface of the slide plate 14 close to the box door 2, and the number of the right-angle blocks 16 is consistent with the toggle rod 8. The end of each toggle rod 8 is correspondingly slidably mounted between the right-angle block 16 and the slide plate 14. A transmission component is also provided between the slide plate 14 and the drying box 1. The notch formed by the right-angle block 16 and the slide plate 14 is downward, that is, when the slide plate 14 moves downward, the two ends of the toggle rod 8 can be restricted.

[0023] The transmission component includes a straight groove 34 opened inside each slide plate 14, and a sliding block 35 is slidably installed inside the straight groove 34, and the internal thread of each sliding block 35 is equipped with a threaded rod 36, and the two ends of the threaded rod 36 are rotatably embedded in the interior of the drying box 1, and each threaded rod 36 extends out of the drying box 1 at one end away from the box door 2, and the exposed ends of the two threaded rods 36 are driven by a synchronous gear belt group. An electric motor is fixedly mounted on the end face of the drying box 1 away from the box door 2, and the output end of the motor is fixed to the end of one of the threaded rods 36. The sliding block 35 and the straight groove 34 are axially sliding, that is, when the position of the threaded rod 36 is fixed, the upper and lower positions of the slide plate 14 will not affect the relationship between the sliding block 35 and the threaded rod 36.

[0024] Working principle: When the product in the mesh plate 5 is baked and cooled, the door 2 needs to be opened. When the product in the mesh plate 5 is taken out, before the staff opens the door 2, the two threaded rods 36 can be driven by the motor to rotate synchronously in the same direction, driving the two slide plates 14 to move in the same direction. Figure 6The position and state in the middle moves toward the door 2, and during the movement of the slide plate 14, since each first gear 10 is in meshing contact with the rack 11 above it, the toggle rod 8 can also rotate counterclockwise when it moves toward the door 2, that is, while the toggle rod 8 pushes the products stuck in the mesh plate 5, the toggle rod 8 can also rotate counterclockwise to lift up the contacted products, thereby separating the products stuck in the mesh plate 5, and due to the upward lifting action of the toggle rod 8, the breakage rate of the products baked and dried in the mesh plate 5 can be reduced.

[0025] In this solution, the surface of the toggle rod 8 may be provided with friction patterns, which can increase the friction between the toggle rod 8 and the product being baked, thus achieving a more obvious lifting effect on the product.

[0026] It is worth noting that the toggle rod 8 is made of carbon alloy, and a magnet is embedded in the rear end face of the bottom of each mesh plate 5. The magnet acts on the toggle rod 8 through its magnetic attraction, which can serve as an initial limit for the toggle rod 8, thereby preventing the mesh plate 5 from shaking and deviating when placed in the drying box 1, causing the toggle rod 8 to be unable to be stuck between the slide plate 14 and the right-angle block 16. Example 2: Please refer to Figure 1 , Figure 2 , Figure 7-Figure 9 This embodiment is a further description of the first embodiment. The fastening unit includes a gear box 21 fixedly arranged on the top of the drying box 1. The input end and the output end of the gear box 21 have the same speed ratio and rotate synchronously in the same direction. The input end of the gear box 21 is fixedly sleeved with a second cam 24. The interior of the box door 2 is provided with a vertical cavity 27. The interior of the cavity 27 is rotatably provided with a plurality of rotating columns 29 distributed in a straight line and at equal distances. The outer surface of each rotating column 29 is fixedly sleeved with a second gear 30 and a push rod 31. The interior of the cavity 27 is also axially sliding. A toothed plate 28 is inserted, and the toothed plate 28 is movably engaged with the second gear 30. Springs 32 are fixedly provided on the upper and lower end surfaces of the toothed plate 28. The bottom of the spring 32 located at the bottom is fixed to the cavity 27, and a touch rod 33 is also fixedly provided on the top of the spring 32 located at the top, and the top of the touch rod 33 slides through the drying box 1. The outer surface of the second cam 24 is in sliding contact with the end of the touch rod 33. The essence of the gear box 21 is a gear transmission box commonly used in the prior art, that is, through the assembly of internal gears, the output end and the input end can be transmitted in a certain relationship.

[0027] The output end of the gear box 21 is fixedly sleeved with a first cam 22 , and the first cam 22 is located between the drying box 1 and the toggle plate 20 . When the first cam 22 rotates, it can push the toggle plate 20 upward.

[0028] A plane portion 23 is provided at the distal end of the first cam 22 . When the plane portion 23 contacts the lower end surface of the toggle plate 20 , the reaction elastic force generated by the two tension springs 19 can temporarily limit the first cam 22 .

[0029] A lever 26 is also fixedly provided on the outer surface of the input end of the gear box 21, and a brake plate 25 is fixedly provided on the end face of the second cam 24 away from the gear box 21. The distance between the brake plate 25 and the front end face of the drying box 1 is consistent with the thickness of the box door 2. One end of the brake plate 25 coincides with the proximal end of the second cam 24, and the other end extends toward the distal end of the second cam 24. The lever 26 facilitates the rotation of the input end of the gear box 21.

[0030] In this embodiment: In this scheme, when the box door 2 is closed, the staff can rotate the input end of the gear box 21 clockwise by 90 degrees through the lever 26. During the rotation of the input end of the gear box 21, the second cam 24 can press the touch rod 33 downward, and the brake plate 25 can also limit the box door 2, thereby realizing the locking process of the box door 2 and the pressing process of the touch rod 33. When the touch rod 33 moves downward, the gear plate 28 is pressed downward by the spring 32, prompting the gear plate 28 to engage the second gear 30 and rotate, so that the push rod 31 is deflected, and the push rod 31 can be against the front end surface of the mesh plate 5, thereby cooperating with the limit block 4 and the support plate 3 to limit and stabilize the mesh plate 5, so as to ensure that the mesh plate 5 will not deviate inside the drying box 1; During the rotation of the input end of the gear box 21, its output end will also rotate synchronously with the first cam 22 in the same direction. The rotation of the first cam 22 releases the toggle plate 20, allowing the toggle plate 20 to move downward under the action of the two tension springs 19, thereby allowing the lifting plate 17 to move downward with the rack 11, and allowing the rack 11 to engage with the first gear 10.
