Technical Field

[0001] The utility model relates to the technical field of white tea withering, in particular to a drying angle adjustment device for a white tea withering machine. Background Art

[0002] The withering technology is very important in the production process of white tea. It is a process in which the fresh leaves entering the factory lose water over a period of time, causing the hard and brittle leaves to wilt and die. The withering methods include sunlight withering, hot air withering, indoor natural withering and double withering.

[0003] The general withering method is to set up multiple trays for holding white tea on the withering stand, and spread the white tea flat on the trays to wither the white tea; when withering in sunlight, in order to improve the withering efficiency of the white tea, it is necessary to adjust the inclination angle of the tray according to the offset of the sun to extend the time that the sun directly shines on the white tea.

[0004] However, currently, the tray is generally tilted by directly driving the tray to rotate with a servo motor. At least the number of servo motors equal to the number of trays needs to be installed on each stand, which is not only complicated to install, but also costly. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] An automatic white tea withering machine, comprising:

[0028] Tray 1, height adjustment mechanism and front and rear adjustment mechanism;

[0029] The tray 1 is used to hold white tea, and a plurality of trays are detachably mounted on the height adjustment mechanism;

[0030] The height adjustment mechanism is used to adjust the height of the tray 1 mounted thereon;

[0031] The front-to-back adjustment mechanism can drive the height adjustment mechanism to move forward and backward to adjust the front-to-back position of the tray 1 .

[0032] When in use, the height position and front-to-back position of the tray 1 can be adjusted by the height adjustment mechanism and the front-to-back adjustment mechanism according to the specific withering method and withering environment, so that the white tea in the tray 1 is in the best withering position.

[0033] For example, when withering indoors, there are environmental and fan restrictions. The front and rear positions of multiple trays 1 can be adjusted through the front and rear adjustment mechanism to save space. After the front and rear positions are fixed, the height position of the tray 1 is adjusted according to the position of the fan to make full use of the fan's air volume.

[0034] There are fewer restrictions on sunlight withering. The number of trays 1 installed on the height adjustment mechanism can be adjusted according to the amount of green leaves of the withered white tea. When the amount of green leaves is small, some trays 1 can be removed from the height adjustment mechanism. When the amount of green leaves is large, trays 1 can be installed on the height adjustment mechanism. The front and rear adjustment mechanisms can be used to adjust the distance between the front and rear withering machines according to the angle of sunlight, so that the white tea can get sufficient light without wasting space.

[0035] Furthermore, the height adjustment mechanism includes two height adjustment components 2 arranged opposite to each other, and both ends of the tray 1 are detachably connected to the two height adjustment components 2 respectively;

[0036] The lower end of the height adjustment component 2 is slidably connected to the slide 3 , and the front-rear adjustment mechanism can drive the height adjustment component 2 to move forward and backward on the slide 3 .

[0037] Furthermore, considering that when withering in the sun outdoors, if you want to improve the withering efficiency, you need to keep it in direct sunlight for a long time. For this reason, the height adjustment component 2 is designed as follows in the utility model:

[0038] The height adjustment assembly 2 includes a vertically arranged bracket 4, the lower end of which is slidably mounted on a slide 3;

[0039] A lifting structure is installed on each of the two brackets 4, each lifting structure is connected to each tray 1 through a connecting piece, and each lifting structure can adjust the height of the connecting piece on the same side as it;

[0040] When the connecting pieces on both sides of the tray 1 are at different heights, the tray 1 is in a tilted state;

[0041] When the connecting pieces on both sides of the tray 1 are at the same height, the tray 1 is in a horizontal state;

[0042] The tilt angle of the tray 1 can be controlled by adjusting the height difference of the connecting parts on both sides of the tray 1 through the two lifting structures;

[0043] According to the rising and setting of the sun, from morning to noon, the tilt angle of the tray 1 is controlled to change from large to small, and from noon to evening, the tilt angle of the tray 1 is controlled to change from small to large, so as to extend the time when the white tea in the tray 1 is directly exposed to sunlight and improve the withering efficiency of the white tea;

[0044] When increasing or decreasing the tilt angle of the tray 1, the lifting structure on one side can be used to control the lifting or lowering of one side of the tray 1, so that the tilt angle of the tray 1 is increased or decreased;

[0045] The lifting structures on both sides may also be operated synchronously, so that one side of the tray 1 is lifted and the other side is lowered, thereby accelerating the speed of increasing or decreasing the tilt angle of the tray 1.

[0046] The inclination angles of multiple trays 1 can be adjusted synchronously through the two lifting structures, which reduces the cost, facilitates installation, and also has the function of adjusting the height of the trays at intervals.

[0047] After the tray 1 is level, the two lifting structures can be operated synchronously to make both sides of the tray 1 rise or fall synchronously, so as to adjust the height of the tray 1 and the withering height of the white tea.

[0048] Furthermore, the lifting structure includes a screw rod 5, a screw motor 6 and a slider 7. The screw rod 5 is vertically rotatably installed in the bracket 4. A plurality of sliders 7 are slidably arranged at equal intervals in the bracket 4. The slider 7 is threadedly connected to the screw rod 5. The screw motor 6 is used to drive the screw rod 5 to rotate.

[0049] The working principle of the lifting structure is: the screw motor 6 drives the screw 5 to rotate. Since the slider 7 is threadedly connected to the screw 5 and is also slidably connected to the bracket 4, the rotation of the screw 5 will drive the slider 7 to move upward or downward to adjust the height of the side of the tray 1 corresponding to the side slider 7.

[0050] When the tilt angle of the tray 1 needs to be increased or decreased, the screw motor 6 on one side can be used to drive the screw 5 to rotate, so that the slider 7 on that side rises or falls, so that the tilt angle of the tray 1 increases or decreases;

[0051] The two screws 5 can also be driven to rotate by the screw motors 6 on both sides, so that the slider 7 on one side rises and the slider 7 on the other side falls, thereby accelerating the speed of increasing or decreasing the tilt angle of the tray 1.

[0052] After the tray 1 is level, the two screw motors 6 can be operated synchronously to make the sliders 7 on both sides rise or fall synchronously, so as to adjust the height of the tray 1 and the withering height of the white tea.

[0053] When it is necessary to increase the tray 1 , the tray 1 can be installed on the vacant slider 7 ; when it is necessary to reduce the tray 1 , the tray 1 can be removed from the slider 7 .

[0054] The specific transmission structure between the screw 5 and the screw motor 6 is:

[0055] A bearing seat 17 is fixedly provided at the upper end of the bracket 4, and a pulley 18 is rotatably mounted on the bearing seat 17. The upper end of the screw 5 is connected to the pulley shaft through a coupling 19, and the pulley on the end of the screw motor 6 is connected to the pulley 18 on the bearing seat 17 through a belt or chain.

[0056] The bearing seat 17, the pulley 18, the coupling 19 and the screw rod 5 are coaxially arranged.

[0057] The screw motor 6 is installed on a vertically arranged mounting frame, and the bottom of the mounting frame is also slidably connected to the slide. The mounting frame is fixed together with the bracket and can slide synchronously on the slide.

[0058] Furthermore, when the tilt angle of the tray 1 changes, the connection position between the tray 1 and the slider 7 changes. In order to smoothly adjust the angle, the present invention provides two embodiments of the connector:

[0059] First Implementation Method

[0060] The connecting member is set as a rotating shaft 20, and the rotating shafts 20 on both sides are respectively rotatably connected to the corresponding sliders 7;

[0061] The rotating shaft 20 on one side is rotatably connected to the corresponding tray 1 , and the rotating shaft 20 on the other side is slidably connected to the corresponding tray 1 .

[0062] Specifically, the rotating shaft 20 is connected to two inclined sides of the tray 1 (the inclined sides refer to the two sides whose angles with the horizontal plane will change when the angle of the tray 1 is adjusted);

[0063] A connecting hole 22 is provided on one of the inclined sides for rotationally connecting with the rotating shaft 20; a connecting groove 21 is provided on the other inclined side, and the rotating shaft 20 on this side is inserted into the connecting groove 21 and is slidingly connected with the connecting groove 21. The end of the connecting groove 21 close to the connecting hole 22 on the opposite side is the inner end, and the end away from it is the outer end.

[0064] When the tilt angle of the tray 1 increases, the shaft 20 slides toward the outer end of the connecting groove 21 relative to the connecting groove 21 ; when the tilt angle of the tray 1 decreases, the shaft 20 slides toward the inner end of the connecting groove 21 relative to the connecting groove 21 .

[0065] Second embodiment (not shown)

[0066] The connecting member is configured as a telescopic rod, and both ends of the telescopic rod are hinged to the corresponding tray 1 and the slider 7 respectively.

[0067] Specifically, the ends of the telescopic rods on both sides are respectively hinged to the two horizontal sides of the tray 1 (the inclined sides refer to the two sides that are always horizontal to the horizontal plane when the angle of the tray 1 is adjusted), and the other ends of the telescopic rods are hinged to the corresponding sliders 7;

[0068] When the tilt angle of the tray 1 increases, the telescopic rod is lengthened; when the tilt angle of the tray 1 decreases, the telescopic rod is shortened.

[0069] Furthermore, the two brackets 4 are staggered, that is, the two height adjustment components 2 are staggered, so that the sliders 7 on both sides of the tray 1 are staggered with the connection points of the tray 1, which facilitates the adjustment of the tilt angle of the tray 1.

[0070] Furthermore, considering that when the tray 1 is tilted, the white tea originally spread out in the tray 1 may gather on the lower side of the tray 1 and affect the withering effect, the utility model provides a raised grid in the tray 1 to prevent the white tea from gathering on one side of the tray 1.

[0071] Furthermore, the slide 3 includes two slide rods 8 arranged in parallel and a slide block 9 slidably sleeved outside the slide rods 8 , and the lower end of the bracket 4 is fixedly mounted on the slide block 9 .

[0072] Furthermore, the front-to-back adjustment mechanism includes two symmetrically arranged front-to-back adjustment components 10, and each front-to-back adjustment component 10 drives a corresponding height adjustment component 2;

[0073] The front-rear adjustment assembly 10 is installed on a power frame 11 at the front side of the slide 3 .

[0074] It should be noted that when adjusting the front and rear position of the tray 1 , the two front and rear adjustment components 10 need to operate synchronously.

[0075] Further, the front and rear adjustment assembly 10 includes a power motor 12, a power wheel 13 and a power rod 14;

[0076] The power wheel 13 is rotatably connected to the power frame 11, one end of the power rod 14 is rotatably connected to the wheel disc 15 of the power wheel 13, and the other end of the power rod 14 is hinged to the slider 7;

[0077] The output end of the power motor 12 is transmission-connected to the power wheel 13 via a belt or a chain.

[0078] The specific working principle is:

[0079] The power motor 12 drives the power wheel 13 to rotate through a belt. When the power wheel 13 rotates, one end of the power rod 14 is driven to move circumferentially with the power wheel 13, so that the other end of the power rod 14 pushes the slider 7 forward or backward to adjust the front and rear position of the tray 1.

[0080] Compared with general linear drive mechanisms such as cylinders, the front-rear adjustment assembly 10 has more components, but is relatively convenient in later repair and maintenance. The distance of the front-rear movement can be adjusted by increasing the length of the connecting rod and the wheel.

[0081] Furthermore, the two power motors 12 are controlled by a pedal switch 16, which can not only synchronously control the two power motors 12, but also control the switch in the form of a foot pedal, so that people can stand upright, and the staff can more intuitively feel the forward and backward movement position of the tray 1, and can control the moving distance more accurately.
