[0001] The utility model belongs to the technical field of tea processing, and particularly relates to a magnetic separation mechanism for tea processing. BACKGROUND

[0002] With the continuous improvement of the quality of life, people's requirements for tea are also continuously improved, which requires that tea processing is more strict. In tea processing, in order to prevent metal substances from being mixed in tea, a magnetic separation device is usually used to screen tea to remove metal substances in tea. However, the magnetic separation roller in the prior art needs to be cleaned manually after being used once to maintain the magnetic separation effect of the magnetic separation roller. Although the cleaning effect is good, it takes a long time, thereby affecting the magnetic separation efficiency of tea.

[0003] In view of this, to solve the above problems, the utility model provides a magnetic separation machine which has good magnetic separation effect and does not need to be cleaned manually, and the mechanism has reasonable structure design, low cost and convenient operation. SUMMARY

[0004] The utility model provides a magnetic separation mechanism for tea processing, which has reasonable structure design, low cost, convenient operation, good magnetic separation effect and does not need to be cleaned manually, and the specific scheme is as follows:

[0005] A magnetic separation mechanism for tea processing includes a support frame and baffles arranged at the top of the support frame on both sides, a conveying belt is arranged between the two baffles, the conveying belt is driven to run by a driving mechanism, a feeding hopper is arranged on the upper side of the baffle at one end of the conveying belt, and a discharge chute is arranged on the lower side of the baffle at the other end of the conveying belt, a layer of magnetic sheets is arranged on the outer side of the conveying belt, a stirring assembly is arranged between the two baffles on the upper side of the magnetic sheets, and a scraping assembly is arranged between the two baffles on the side of the conveying belt away from the stirring assembly.

[0006] Further, the scraping assembly includes a U-shaped mounting plate arranged horizontally between the two baffles, and a scraper is obliquely connected to one end of the mounting plate, and the end of the scraper is tightly attached to the conveying belt.

[0007] Further, a brush roller is arranged horizontally between the two side walls of the mounting plate, a first motor is arranged on the outer side of the mounting plate, and the output shaft of the first motor is connected in transmission to the brush roller.

[0008] Further, an auxiliary plate is arranged horizontally between the two baffles on the upper and lower sides of the conveying belt, and the bottom end surface of the auxiliary plate is attached to the side surface of the conveying belt.

[0009] Further, the stirring assembly includes a rotating shaft arranged horizontally between the two baffles on the upper side of the conveying belt, a plurality of L-shaped stirring rods are arranged at intervals along the length direction of the rotating shaft, a second motor is arranged on the outer side of the baffles, and the second motor is connected in transmission to the rotating shaft.

[0010] Furthermore, multiple material feeding components are spaced apart between the two baffles on the upper side of the conveyor belt. These multiple material feeding components are connected by a belt and driven by a second motor.

[0011] The beneficial effects of this utility model are:

[0012] This utility model discloses a magnetic separation mechanism for tea processing. By incorporating a scraping component, a material-dispersing component, and magnetic sheets mounted on the outer surface of the conveyor belt, the tea leaves are dispersed by L-shaped dispersing rods on multiple dispersing components after entering the conveyor belt from the feed hopper. This prevents the tea leaves from clumping together, allowing all metal substances in the tea leaves to be dispersed and adsorbed by the magnetic sheets, resulting in more thorough magnetic separation. Consequently, the tea leaves are cleanly discharged from the discharge trough. When the mechanism reaches the scraper, the scraper removes any metal substances adhering to the magnetic sheets, and the brush rollers sweep them away, eliminating the need for manual cleaning. This mechanism features a reasonable structural design, low cost, and ease of use. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] See Figures 1-5A magnetic separation mechanism for tea processing includes a support frame 1 and baffles 2 spaced apart on both sides of the top of the support frame 1. A conveyor belt 3 is provided between the two baffles 2. The conveyor belt 3 is driven by a drive mechanism 4, which is a motor. A feed hopper 9 is provided on the baffle 2 on the upper side of one end of the conveyor belt 3, and a discharge chute 5 is provided on the baffle 2 on the lower side of the other end. A layer of magnetic sheet 6 is provided on the outer surface of the conveyor belt 3. A material-pulling component 7 is provided between the two baffles 2 on the upper side of the magnetic sheet 6. A scraping component 8 is provided between the two baffles 2 on the side of the conveyor belt 3 away from the material-pulling component 7.

[0021] The preferred scraping assembly 8 includes a U-shaped mounting plate 81 horizontally disposed between two baffles 2. The upper part of the two side walls of the U-shaped mounting plate 81 is detachably connected to the two baffles 2 by bolts. A scraper 82 is obliquely connected to one end of the mounting plate 81, and the end of the scraper 82 is tightly fitted with the conveyor belt 3.

[0022] A brush roller 83 is horizontally arranged between the two side walls of the preferred mounting plate 81. The brush roller 83 is located behind the scraper 82. A first motor 84 is provided on the outer side of the mounting plate 81. The output shaft of the first motor 84 is connected to the brush roller 83 for transmission.

[0023] An auxiliary plate 10 is horizontally provided between the two baffles 2 on the upper and lower sides of the preferred conveyor belt 3. The auxiliary plate 10 has a U-shaped structure and its two sides are detachably connected to the two baffles 2 by bolts. The bottom surface of the auxiliary plate 10 is in contact with the side of the conveyor belt 3. The setting of the auxiliary plate 10 makes it more stable when the scraper 82 scrapes the metal material on the magnetic sheet 6.

[0024] The preferred material feeding assembly 7 includes a rotating shaft 71 horizontally disposed between two baffles 2 on the upper side of the conveyor belt 3. The rotating shaft 71 is provided with a plurality of L-shaped material feeding rods 72 spaced apart along its length. A second motor 73 is provided on the outer side of the baffles 2. The second motor 73 is connected to the rotating shaft 71 for transmission.

[0025] The preferred conveyor belt has multiple material feeding components 7 spaced apart between the two baffles 2 on the upper side. The multiple material feeding components 7 are connected by a belt 74 and driven by a second motor 73. The two baffles 2 are equipped with three sets of material feeding components 7, and the two rotating shafts 71 are connected by a belt 74.

[0026] The working principle of the magnetic separator for tea processing of this utility model is as follows: First, the drive motor 4, the first motor 84 and the second motor 73 are started simultaneously to make the conveyor belt 3, the rotating shaft 71 and the brush roller 83 run at the same time. Then, the tea is poured into the feed hopper 9. When the tea passes through several L-shaped feed bars 72, the continuous rotation of the bars allows the tea to pass through evenly and also peels off the metal substances contained in the tea, which are then adsorbed by the magnetic sheet 6. When the tea reaches the end of the conveyor belt 3, it is discharged through the discharge chute 5. When the adsorbed metal substances reach the scraper 82, the auxiliary plate 10 and the scraper 82 make the conveyor belt 3 and the magnetic sheet 6 fit tightly together. As the metal substances on the magnetic sheet 6 gradually accumulate, the scraper 82 can gradually scrape off the metal substances adsorbed on the magnetic sheet. When the tea reaches the brush roller 83, the small particles or powdery metal substances adsorbed on the magnetic sheet 6 can be swept away by the brush roller 83.
