Description

Technical Field

[0001] The utility model relates to the technical field of tea conveying devices, in particular to a thickness regulating mechanism for a black tea withering conveying device. Background Art

[0002] Black tea contains vitamins, caffeine, amino acids, minerals, polysaccharides, tea polyphenols and other nutrients and functional ingredients. Studies have shown that black tea has the effect of assisting in lowering blood sugar, blood pressure and blood lipids. More and more people like to drink black tea. The withering of black tea is an important step in tea processing. The main purpose is to reduce the tension of tea cells by evaporating part of the water, making the leaf stems softer and increasing the toughness of the buds and leaves, which is convenient for rolling into strips. When the black tea is withered, a conveying device is required to transport it to the withering equipment.

[0003] Since black tea is generally introduced into the conveying device through a loading hopper, the tea leaves will be in piles. In order to ensure the uniformity of subsequent withering, the black tea leaves need to be dispersed and made uniform in thickness. For example, patent No. CN212639252U3 discloses a thickness adjustment device in an automatic feeding storage trough for fresh tea leaves. By loosening the limit plate bolt, holding the handle and driving the adjustable support rod and the scraper to rotate, the distance between the scraper and the feeding conveyor is adjusted, and then the conveying thickness of the tea leaves is adjusted. However, this method requires manual operation and adjustment, which is time-consuming and labor-intensive, and has a low degree of automation. Utility Model Content

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.

[0021] See also Figure 1-5 The utility model provides an embodiment: a thickness adjustment mechanism for a black tea withering conveying device, comprising a conveying device body 1, an upper hopper 2, a frame 4 and a material distribution plate 6. The upper hopper 2 is arranged above one side of the conveying device body 1, and a discharge port 5 is arranged at one end of the conveying device body 1 away from the upper hopper 2. The conveying device body 1 is arranged on one side of the withering device, and the discharge port 5 is connected to the feed port of the withering device accordingly.

[0022] Both sides of the upper hopper 2 are rotatably connected with baffles 19 through hinges, and the lower part of the baffles 19 is connected to the inner wall of the upper hopper 2 through a return spring 20;

[0023] The black tea leaves are introduced through the upper hopper 2. When the tea leaves are introduced, they squeeze the baffle 19, causing the baffle 19 to compress the return spring 20. The tea leaves fall through the gap of the baffle 19 and enter the conveying device body 1, which helps to slow down the feeding speed.

[0024] A frame 4 is mounted on the conveying device body 1 on one side of the upper hopper 2, a lifting plate 7 is arranged at the top of the frame 4, and a roller 8 is arranged below the lifting plate 7 through a rotating shaft 18, and material balancing plates 6 are evenly distributed on the outside of the roller 8, and 4 groups of material balancing plates 6 are arranged, and the material balancing plates 6 are distributed in a concentric circle structure around the roller 8;

A driven gear 13 is provided at one end of the rotating shaft 18 close to the driving gear 12, and the driven gear 13 is meshed with the driving gear 12.

[0026] The conveying device body 1 conveys the black tea leaves. When the black tea leaves are conveyed to the bottom of the frame 4, the second rotary drive mechanism 11 drives the driving gear 12 to rotate, so that the driven gear 13, the rotating shaft 18 and the drum 8 rotate, and the tea leaves are scattered by the material distribution plate 6 so that the tea leaves pass through evenly with a certain thickness.

[0027] The outer side of the drum 8 is evenly provided with grooves 15, and the inside of the grooves 15 is provided with pressure pieces 17 through buffer springs 16, and one end of the pressure pieces 17 is connected to the material balancing plate 6;

[0028] Limiting grooves are provided on both sides of the groove 15, and limiting blocks are provided on both sides of one end of the pressure-bearing member 17;

[0029] When the material distribution plate 6 is used to spread the black tea leaves, the material distribution plate 6 is subjected to the force from the tea leaves, which causes the pressure-bearing member 17 to compress the buffer spring 16 in the groove 15. The pressure is dispersed and buffered by the resilience of the buffer spring 16, so that the material distribution plate 6 is in flexible contact with the tea leaves, and the black tea leaves are not easily damaged.

[0030] A screw rod 14 is provided on one side of the frame body 4, and a driving block 10 is sleeved on the screw rod 14, one end of the driving block 10 is connected to the lifting plate 7, and a first rotary drive mechanism 3 is fixed to one end of the top of the frame body 4, and the output end of the first rotary drive mechanism 3 is connected to the screw rod 14;

[0031] The first rotary drive mechanism 3 can drive the screw rod 14 to rotate, so that the driving block 10 and the lifting plate 7 can move up and down along the screw rod 14, so that the distance between the material distribution plate 6 and the tea leaves can be adjusted, and the thickness of the black tea leaves to be transported can be automatically adjusted without manual operation, and the degree of automation is high;

[0032] A guide rod 9 is provided on the side of the frame body 4 away from the screw rod 14, and a side of the lifting plate 7 close to the guide rod 9 is slidably sleeved with the guide rod 9 through a guide sleeve to guide and limit the lifting plate 7;

[0033] The specific model specifications of the first rotary drive mechanism 3 and the second rotary drive mechanism 11 need to be determined by selection calculation based on the specification parameters of the device, and the selection calculation method is a prior art, so it will not be described in detail.

[0034] Working principle: When the embodiment of the present application is in use, the conveying device body 1 is arranged on one side of the withering equipment, the discharge port 5 is connected correspondingly to the feed port of the withering equipment, and the black tea leaves are introduced through the upper hopper 2. When the tea leaves are introduced, the baffle 19 is squeezed, so that the baffle 19 compresses the reset spring 20, and the tea leaves fall through the gap of the baffle 19 and enter the conveying device body 1, which is conducive to slowing down the feeding speed. After that, the conveying device body 1 conveys the black tea leaves. When it is conveyed to the bottom of the frame 4, the second rotary drive mechanism 11 drives the active gear 12 to rotate, so that the driven gear 13 and the rotating shaft 18 and the drum 8 rotate, and the tea leaves are scattered by the material balancing plate 6 to make it in a A certain thickness passes through evenly, and at the same time, the first rotary drive mechanism 3 can drive the screw rod 14 to rotate, so that the driving block 10 and the lifting plate 7 can move up and down along the screw rod 14, so that the distance between the material balancing plate 6 and the tea leaves can be adjusted, and the thickness of the black tea leaves to be conveyed can be automatically adjusted without manual operation, and the degree of automation is relatively high. In addition, when the material balancing plate 6 is breaking up and spreading the black tea leaves, the material balancing plate 6 is subjected to the force from the tea leaves, which prompts the pressure-bearing piece 17 to compress the buffer spring 16 in the groove 15, and the pressure is dispersed and buffered by the rebound performance of the buffer spring 16, so that the material balancing plate 6 is in flexible contact with the tea leaves, and it is not easy to damage the black tea leaves.
