Description

Technical Field

[0001] This utility model relates to the field of white tea production, and in particular to a withering machine that provides uniform heating. Background Technology

[0002] Withering white tea removes excess moisture, bringing the tea leaves to a certain degree of dryness for easier storage and later consumption. Even heating ensures that the moisture in each leaf evaporates at a uniform rate, preventing some leaves from drying out too quickly while others remain highly moist, which would negatively impact the overall withering process and ultimately result in inconsistent tea quality.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: Existing withering machines generally include structures such as support mechanisms, heating mechanisms, and frames. When evaporating moisture from white tea, they mostly place the white tea raw materials directly on the placement platform and use the heating mechanism to heat and dry them. Since a large amount of white tea is piled together and the position of the heating mechanism remains unchanged, the white tea in the middle layer will evaporate more slowly, ultimately affecting the overall evaporation effect.

[0004] Therefore, those skilled in the art have provided a withering machine that provides uniform heating to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a withering machine that provides uniform heating. The moving mechanism prevents workers from being burned, and the rotating mechanism ensures that the white tea is dried to a consistent degree.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a withering machine with uniform heating, comprising a moving mechanism and a rotating mechanism, wherein the moving mechanism comprises a housing, a screw is rotatably connected to one side of the inner wall of the housing, a slider is threadedly connected to the outer wall of the screw, a fixing block is rotatably connected to the front end of the screw, and the outer wall of the fixing block is fixedly connected to the inner wall of the housing;

[0007] The rotating mechanism includes multiple platforms and a second motor. The multiple platforms are fixedly connected to a second rotating shaft at one end near the slider. The multiple second rotating shafts are rotatably connected to a rotating block at one side near the slider. The multiple rotating blocks are fixedly connected to a turntable at one end away from the multiple platforms.

[0008] Furthermore, each of the multiple trays is fixedly connected to a No. 1 rotating shaft at the end away from the turntable, and the ends of the multiple No. 1 rotating shafts are rotatably embedded and connected to a limit block at the ends away from the turntable.

[0009] Furthermore, a fixed shaft is fixedly connected to one end of each of the limiting blocks away from the multiple first rotating shafts, and a support rod is fixedly connected to the outer wall of each of the fixed shafts.

[0010] Furthermore, a movable block is slidably connected inside the housing on the side away from the turntable, and a rotating column is rotatably connected to the inner wall of the movable block near the turntable. The outer wall of the rotating column is fixedly connected to multiple support rods.

[0011] Furthermore, the output end of the second motor is fixedly connected to the center of the turntable near the slider, and the inner wall of the slider is fixedly connected to the outer wall of the second motor.

[0012] Furthermore, the slider is slidably disposed on the side of the housing near the screw, and multiple electric heating rods are fixedly disposed on the top and bottom of the inner wall of the housing.

[0013] Furthermore, a locking block is fixedly connected to the outer wall of the rear end face of the housing near the slider, and a No. 1 motor is fixedly connected to the inner wall of the locking block. The output end of the No. 1 motor is fixedly connected to the rear end face of the screw.

[0014] Furthermore, a door panel is hinged to the front end of the housing via a hinge, and a handle is fixedly provided on the front end of the door panel away from the screw.

[0015] This utility model has the following beneficial effects:

[0016] 1. The present invention proposes a withering machine with uniform heating. When the white tea is taken out after evaporation, the output end of the No. 1 motor drives the screw to rotate. The screw causes the threaded slider to move forward along the inner wall of the shell. When the slider moves forward, it drives the rotating mechanism to move forward and move out of the shell. At this time, the worker can take out the white tea without having to put his arm into the shell, reducing the probability of the worker being burned. At the same time, it slightly reduces the labor intensity of the worker and increases the humanization of the equipment.

[0017] 2. The withering machine proposed in this utility model provides a uniformly heated system. When evaporating moisture, the output end of motor No. 2 drives the turntable and multiple rotating blocks to rotate backward. The multiple rotating blocks drive the No. 2 rotating shaft on the inner wall to rotate backward. Due to the weight of the white tea in the tray, when the rotating blocks drive the No. 2 rotating shaft to rotate backward, the tray rotates forward slightly to correct it. On the other side of the tray, the No. 1 rotating shaft rotates forward along the limit block to correct it, and at the same time, it drives the limit block to rotate. When the white tea is slightly turned over in the tray, the white tea can be dried more thoroughly. At the same time, as the turntable rotates, the position is constantly changed to ensure that all the white tea is heated evenly. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 The present invention provides an embodiment of a withering machine with uniform heating, comprising a moving mechanism 1 and a rotating mechanism 4. The moving mechanism 1 includes a housing 101, a screw 104 rotatably connected to one side of the inner wall of the housing 101, a slider 106 threadedly connected to the outer wall of the screw 104, and a fixing block 107 rotatably connected to the front end of the screw 104. The outer wall of the fixing block 107 is fixedly connected to the inner wall of the housing 101.

[0027] The rotating mechanism 4 includes multiple trays 403 and a second motor 408. The multiple trays 403 are fixedly connected to a second rotating shaft 411 at one end near the slider 106. The multiple second rotating shafts 411 are embedded and rotatably connected to a rotating block 402 at one side near the slider 106. The multiple rotating blocks 402 are fixedly connected to a turntable 401 at one end away from the multiple trays 403.

[0028] Specifically, when you need to take out the white tea, grip the handle 2 to turn the door panel 3 to the left along the hinge. The motor 103 will work to drive the screw 104 to rotate. The screw 104 will rotate along the inner wall of the fixing block 107, causing the threaded slider 106 to move forward along the inner wall of the housing 101. The forward movement of the slider 106 will drive the rotating mechanism 4 forward. There is no need for the worker to put their arm into the inner wall of the housing 101 to prevent burns.

[0029] Reference Figures 1-5 Multiple trays 403 are fixedly connected to a first rotating shaft 404 at the end away from the turntable 401. The ends of the first rotating shafts 404 away from the turntable 401 are rotatably embedded and connected to limit blocks 405. The ends of the limit blocks 405 away from the first rotating shafts 404 are fixedly connected to fixed shafts 406. Support rods 407 are fixedly connected to the outer walls of the fixed shafts 406. A movable block 409 is slidably connected inside the housing 101 on the side away from the turntable 401. A rotating column 410 is rotatably connected to the inner wall of the movable block 409 near the turntable 401. The outer wall of the rotating column 410 is fixedly connected to the support rods 407. The output end of the second motor 408 is connected to the turntable 401. A fixed connection is made at the center of the side near the slider 106. The inner wall of the slider 106 is fixedly connected to the outer wall of the second motor 408. The slider 106 is slidably disposed on the side of the housing 101 near the screw 104. Multiple electric heating rods 105 are fixedly disposed at the top and bottom of the inner wall of the housing 101. A locking block 102 is fixedly connected to the outer wall of the rear end face of the housing 101 near the slider 106. A first motor 103 is fixedly connected to the inner wall of the locking block 102. The output end of the first motor 103 is fixedly connected to the rear end face of the screw 104. A door panel 3 is hinged to the front end face of the housing 101. A handle 2 is fixedly disposed on the front end face of the door panel 3 away from the screw 104.

[0030] Specifically, the No. 2 motor 408 drives the turntable 401 and multiple rotating blocks 402 to rotate backward. The rotating blocks 402 drive the No. 2 rotating shaft 411 on the inner wall to revolve backward. At the same time, due to the weight of the white tea in the tray 403, the tray 403 rotates forward slightly to correct itself. On the other side of the tray 403, the No. 1 rotating shaft 404 rotates forward along the inner wall of the limit block 405 to correct itself, and at the same time, it drives the limit block 405 to rotate. The multiple limit blocks 405 continue to drive the support rod 407 to rotate. The support rod 407 continues to drive the rotating column 410 to rotate along the inner wall of the moving block 409. This can keep the white tea continuously turning slightly on the inner wall of the tray 403, and at the same time, it constantly changes position with the rotation of the turntable 401 to ensure that the drying quality of all white tea is consistent.

[0031] Working principle: Hold the handle 2 and open the door panel 3 to the left, then start the first motor 103. The output end drives the screw 104 to rotate. The screw 104 rotates along the inner wall of the housing 101 and the inner wall of the fixed block 107, causing the slider 106 to move forward along the inner wall of the housing 101. At the same time, it drives the rotating mechanism 4 to move forward, putting the white tea into multiple trays 403 for moisture evaporation. The trays 403 are fixedly equipped with a mesh screen to prevent the white tea from falling.

[0032] Next, the second motor 408 is started, and the output end drives the turntable 401 to rotate backward. The turntable 401 drives multiple rotating blocks 402 to rotate backward. The rotating blocks 402 drive the second rotating shaft 411 on the inner wall to rotate backward. At the same time, due to the weight of the white tea in the tray 403, the tray 403 makes a small correction rotation forward when the rotating blocks 402 drive the second rotating shaft 411 to rotate backward. On the other side, the tray 403 drives the first rotating shaft 404 to make a correction rotation forward along the inner wall of the limit block 405, and at the same time, it revolves with the limit block 405. Multiple limit blocks 405 drive the support rod 407 to rotate, and the support rod 407 drives the rotating column 410 to rotate along the inner wall of the moving block 409.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
