Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea processing screening device. Background Art

[0002] Tea leaves are the leaves and buds of the tea tree, which can be processed into various types of tea beverages, such as green tea, black tea, etc. Tea leaves contain a variety of chemical components that are beneficial to the human body, including catechins, caffeine, inositol, etc. These components have a positive impact on health. Among them, tea leaves are usually screened using screening devices during processing. The current screening devices are generally based on shaking screening and suction filtration. Among them, shaking screening uses a machine to shake the wire mesh, which causes huge losses to the tea leaves. Suction filtration easily allows dust in the air to adhere to the tea leaves, affecting the quality of the tea leaves.

[0003] In order to address the above problems, a Chinese patent with an existing announcement number of CN215940632U proposes a screening device for tea processing, which drives the fan blades to rotate through a fan and allows the wind to blow toward the tea leaves falling along the electric conveyor belt, thereby filtering the dust and fine hair of the fallen tea leaves through a tea filter and a dust and fine hair filter, reducing the loss of tea leaves and ensuring the screening quality of the tea leaves.

[0004] However, although the above-mentioned screening device for tea processing can blow the tea leaves to the tea filter and the dust and fine hair filter for filtering through the fan, thereby reducing the loss of tea leaves and ensuring the screening quality of tea leaves, after long-term use, the tea filter and the dust and fine hair filter of the screening device for tea processing are prone to clogging, resulting in a problem of reduced tea screening effect. Therefore, the utility model provides a tea processing screening device to meet the needs. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0028] like Figures 1 to 5 As shown, an embodiment of the utility model provides a tea processing and screening device, including a screening bin 1, whose top and bottom are relatively connected to a feed hopper 3 and a discharge port 7, a fan 10 and a screen 8 are relatively arranged along the discharge port 7 in the screening bin 1, the fan 10 is driven by a motor 11, a cleaning component 6 for cleaning the screen 8 is provided on the screening bin 1, the cleaning component 6 includes a cleaning brush 62, which is slidably connected to the screening bin 1 through two sliders 63, a slide groove 15 for sliding the slider 63 is provided in the screening bin 1, a cleaning end of the cleaning brush 62 is fitted with the screen 8, two reciprocating screw rods 61, which respectively penetrate and are threadedly connected to the slider 63, the two reciprocating screw rods 61 are connected by a belt transmission mechanism 64, and the reciprocating screw rods 61 are driven by a motor 2 65.

[0029] Specifically, after the tea leaves enter from the feed hopper 3, the fan 10 is driven to rotate by the motor 11, and the fan 10 blows the impurities in the tea leaves toward the filter, so that smaller dust is filtered by the filter, and the tea leaves fall to the discharge port 7 for discharge. When the filter needs to be cleaned, one of the reciprocating screws 61 is driven to rotate by the motor 2 65, and the two reciprocating screws 61 are rotated under the transmission of the belt transmission mechanism 64, so that the two sliders 63 drive the cleaning brush 62 to move up and down and clean the surface of the filter, thereby ensuring the normal use of the filter. The overall structure is simple, which avoids the phenomenon of the filter being blocked after long-term use, ensures the screening quality of the tea leaves, and solves the problem that the tea filter and the dust and fine hair filter of the existing tea processing and screening device are easily blocked after long-term use, thereby causing the tea screening effect to decrease.

[0030] like Figure 1 and Figure 4 As shown, in this embodiment, a quantitative bin 5 is connected between the screening bin 1 and the feed hopper 3, a rotating shaft 12 is rotatably connected in the quantitative bin 5, a plurality of fixed plates 13 are arranged along the circumference direction of the rotating shaft 12, a magnet 2 which is attracted to the fixed plate 13 is fixedly connected to the side of the quantitative bin 5, the fixed plate 13 is made of iron, and a counterweight 14 is fixedly connected to the bottom of the plurality of fixed plates 13. Specifically, after the tea leaves enter the quantitative bin 5 along the feed hopper 3, the tea leaves will fall onto the fixed plate 13. When the weight of the tea leaves on the fixed plate 13 opposite to the feed port reaches When it reaches the specified value, the magnet 2 can no longer attract the fixed block, so that the fixed plate 13 rotates, causing the tea leaves to fall into the screening bin 1. At the same time, the other fixed plate 13 continues to be adsorbed by the magnet 2 to continue the quantitative screening of the tea leaves. The setting of the counterweight block 14 can speed up the rotation between the multiple fixed plates 13 and improve the efficiency of the quantitative screening of the tea leaves. It should be noted that the counterweight block 14 does not affect the connection between the adjacent fixed plates 13 and the magnet 2. At the same time, in this embodiment, there are four fixed plates 13.

[0031] like Figure 3 As shown, in this embodiment, the screening bin 1 is provided with a controller 9 for controlling motor 1 11 and motor 2 65 .

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the feed hopper 3 is a funnel-shaped structure.

[0033] like Figure 4As shown, in the present embodiment, a plurality of exhaust holes 4 are provided on the side of the screening bin 1 facing the fan 10, and a collecting groove 16 is formed between the exhaust holes 4 and the filter. Specifically, the exhaust holes 4 can ensure that the wind flow of the fan 10 can be discharged onto the screen 8 and discharged along the exhaust holes 4, thereby ensuring the stability of the wind flow direction of the fan 10 and improving the screening efficiency and effect of the tea leaves. At the same time, the collecting groove 16 can collect the impurities after screening.

[0034] Working principle:

[0035] After the tea leaves enter the quantitative bin 5 along the feed hopper 3, the tea leaves will fall onto the fixed plate 13. When the mass of the tea leaves on the fixed plate 13 opposite to the feed port reaches a specified value, the magnet 2 cannot attract the fixed block, so that the fixed plate 13 rotates, causing the tea leaves to fall into the screening bin 1. At the same time, the other fixed plate 13 continues to be attracted by the magnet 2, so as to continue the quantitative screening of the tea leaves. At this time, the controller 9 controls the motor 11 to drive the fan 10 to rotate, and the fan 10 blows the impurities in the tea leaves to the filter screen, so that the smaller dust is filtered by the filter screen, and the tea leaves fall to the discharge port 7 for discharge. When the filter needs to be filtered, the fan 10 is turned on and the fan 10 is turned on. When the net is to be cleaned, the controller 9 controls the motor 2 65 to drive one of the reciprocating screws 61 to rotate, and the two reciprocating screws 61 are rotated under the transmission of the belt transmission mechanism 64, so that the two sliders 63 drive the cleaning brush 62 to move up and down and clean the surface of the filter, thereby ensuring the normal use of the filter. The overall structure is simple, which avoids the clogging of the filter after long-term use, ensures the screening quality of tea leaves, and solves the problem that the tea filter and the dust and fine hair filter of the existing tea processing and screening device are prone to clogging after long-term use, thereby causing the tea screening effect to decrease.
