Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and more specifically to a device for separating tea leaves from tea dust. Background Technology

[0002] During the storage and transportation of tea products, tea leaves may break into dust. The presence of tea dust reduces the appearance and quality of the tea. Therefore, before selling the tea, it is necessary to use a separation device to separate the tea leaves from the tea dust.

[0003] A search revealed an existing patent (publication number: CN217094387U) that discloses a tea leaf and tea dust separation device. In use, by setting up a separation mechanism, when tea leaves fall onto the separation plate, a motor drives a rotating column, which in turn drives a centrifugal wheel. Under the action of the centrifugal wheel and a spring, the separation plate vibrates, thus separating the tea leaves from the tea dust, improving the separation efficiency. The tea dust can be cleaned using a drawer. However, the inventors discovered the following problem with the existing technology during the development of this invention: the separation device cannot easily replace the separation plate when separating tea leaves and tea dust. This results in a fixed mesh size on the separation plate surface. In actual use, tea leaves vary in size and shape depending on the type, thus requiring the use of separation plates with different mesh sizes depending on the type of tea. The aforementioned separation device makes it difficult to easily replace separation plates with different mesh sizes.

[0004] In view of this, the present invention proposes a conveniently adjustable tea leaf and tea dust separation device to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tea leaf and tea dust separation device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a tea leaf and tea dust separation device, including a chassis, a separation chamber inside the chassis, a feed hopper embedded in the top of the chassis, a discharge plate on the bottom side of the front of the chassis, a connecting frame between the feed hopper and the discharge plate inside the chassis, the center of the connecting frame being vertically through, a separation box on the surface of the connecting frame, a filter screen plate on the bottom side of the separation box, the connecting frame being movably connected to the chassis, the number of separation boxes on the surface of the connecting frame being three, the filter screen plate inside each separation box having a different mesh diameter, a window for the connecting frame and the separation box to move on the side wall of the chassis, and an adjustment component between the chassis and the separation box;

[0007] The adjustment assembly includes built-in slots on the front and rear sides of the connecting frame. A limit slide rod is fixedly installed on the inner wall of the built-in slot. A fixed seat is fixedly installed on the inner wall of the chassis. The limit slide rod is slidably connected to the fixed seat. A straight rack is fixedly installed at the bottom of the connecting frame. A drive motor is fixedly installed on the right side of the chassis. A gear plate is fixedly installed on the output shaft surface of the drive motor. The gear plate and the straight rack mesh with each other.

[0008] Furthermore, a control panel is fixedly installed on the front of the chassis, and the control panel is electrically connected to an external power supply via wires.

[0009] As a further description of the above technical solution: by setting up a control panel, it is convenient to control the working status of the drive motor, thereby realizing the adjustment and control of the position of the separation box, which improves the ease of use.

[0010] Furthermore, a support spring is fixedly installed on the inner bottom wall of the separation box, the top end of the support spring is fixed to the bottom end of the filter screen plate, the filter screen plate is flexibly connected to the separation box through the support spring, and a vibration component is provided between the chassis and the filter screen plate.

[0011] As a further description of the above technical solution: by setting a support spring, when using the filter screen to separate tea leaves, the elastic deformation of the support spring can be used to make the filter screen vibrate to a certain extent, thereby improving the separation efficiency of tea leaves and tea dust and preventing tea dust from remaining on the filter screen.

[0012] Furthermore, the vibration assembly includes a geared motor fixedly mounted on the back of the chassis, a cam rotatably connected to the inner wall of the chassis, the output shaft of the geared motor being coaxially fixed with the cam, and the cam corresponding to the bottom side of the filter screen.

[0013] As a further description of the above technical solution: by setting up a vibration component and using a geared motor to drive the cam to rotate, based on the correspondence between the cam and the bottom side of the filter screen, the filter screen can be pushed to vibrate up and down during the rotation of the cam, thereby further improving the separation effect of tea leaves and tea dust.

[0014] Furthermore, the separation box and the connecting frame are detachably connected, and a locking assembly is provided between the separation box and the connecting frame. The locking assembly includes four insertion slots opened on the bottom side of the separation box. The four insertion slots are distributed in a rectangular array at the four corners of the bottom side of the separation box. An insertion rod is fixedly installed on the upper surface of the connecting frame. The insertion rod is inserted into the insertion slot, and a positioning hole is opened on the surface of the insertion rod. Positioning screws are threaded to both the front and rear sides of the separation box, and the positioning screws are inserted into the positioning holes.

[0015] As a further description of the above technical solution: by detachably connecting the separation box and the connecting frame, and by setting a locking component, the positioning screw is locked and positioned by being inserted into the positioning hole, which facilitates the disassembly and replacement of the separation box, thereby realizing the purpose of quickly replacing filter screens of different mesh sizes and removing them to pour out tea leaves, thus improving the flexibility and practicality of the device.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with existing technologies, this tea and tea dust separation device introduces tea leaves into the machine casing through a feed hopper. Under gravity, the tea leaves fall into the separation box. Due to the separation effect of the filter screen, the tea leaves remain inside the separation box, while the tea dust is discharged to the outside of the machine casing along the discharge plate. During the separation process, by setting an adjustment component, under the support and limiting effect of the limiting slide rod on the connecting frame, the drive motor drives the gear plate to rotate. Based on the meshing of the gear plate and the straight rack, the connecting frame can be moved left and right, realizing the purpose of switching and adjusting the separation box and the filter screen. This achieves the effect of quickly switching and adjusting the filter screen with different mesh sizes, meeting the needs of separating different varieties of tea and tea dust.

[0018] 2. Compared with existing technologies, this tea and tea dust separation device, through the addition of a control panel, facilitates the control of the drive motor's operating status, thereby enabling adjustment and control of the separation box position and improving ease of use. By incorporating a support spring, the elastic deformation of the spring causes the filter plate to vibrate during tea leaf separation, improving the separation efficiency and preventing tea dust residue from remaining on the filter plate. Furthermore, by using a vibration component and a geared motor to drive a cam, the cam's position relative to the bottom of the filter plate causes it to vibrate up and down during rotation, further enhancing the tea and tea dust separation effect.

[0019] 3. Compared with the prior art, this tea and tea dust separation device, through the detachable connection of the separation box and the connecting frame, and the setting of the locking component, uses the positioning screw to lock and position inside the positioning hole, which can facilitate the disassembly and replacement of the separation box, thereby realizing the purpose of quickly replacing the filter screen with different mesh sizes and removing the tea leaves to pour out, thus improving the flexibility and practicality of the device.

[0030] By setting up the control panel 12, it is convenient to control the overall working status of the device.

[0031] The machine casing 1 has a separation chamber inside. The top of the machine casing 1 is fitted with a feed hopper 2. The bottom of the front of the machine casing 1 is provided with a discharge plate 3. The inside of the machine casing 1 is provided with a connecting frame 4 between the feed hopper 2 and the discharge plate 3. The center of the connecting frame 4 is open from top to bottom. The surface of the connecting frame 4 is provided with a separation box 5. The bottom of the separation box 5 is provided with a filter screen plate 6.

[0032] The tea leaf and tea dust separation device feeds tea leaves into the machine housing 1 through the feed hopper 2. The tea leaves fall into the separation box 5 under the action of gravity. Under the separation effect of the filter screen 6, the tea leaves remain inside the separation box 5, while the tea dust is discharged to the outside of the machine housing 1 along the discharge plate 3.

[0033] A support spring 13 is fixedly installed on the inner bottom wall of the separation box 5. The top end of the support spring 13 is fixed to the bottom end of the filter screen plate 6. The filter screen plate 6 is flexibly connected to the separation box 5 through the support spring 13.

[0034] By setting the support spring 13, when using the filter screen 6 to separate tea leaves, the elastic deformation of the support spring 13 can be used to make the filter screen 6 vibrate to a certain extent, thereby improving the separation efficiency of tea leaves and tea dust and preventing tea dust from remaining on the filter screen 6.

[0035] A vibration assembly is installed between the casing 1 and the filter screen 6.

[0036] The vibration assembly includes a geared motor 14 fixedly mounted on the back of the housing 1. A cam 15 is rotatably connected to the inner wall of the housing 1. The output shaft of the geared motor 14 is coaxially fixed with the cam 15. The cam 15 corresponds to the bottom side of the filter screen 6.

[0037] By setting up a vibration component, the cam 15 is driven to rotate by the geared motor 14. Based on the correspondence between the cam 15 and the bottom side of the filter screen 6, the filter screen 6 can be pushed to vibrate up and down during the rotation of the cam 15, thereby further improving the separation effect of tea leaves and tea dust.

[0038] The separation box 5 and the connecting frame 4 are detachably connected, and a locking component is provided between the separation box 5 and the connecting frame 4.

[0039] The locking assembly includes four insertion slots 16 on the bottom side of the separation box 5. The four insertion slots 16 are arranged in a rectangular array at the four corners of the bottom side of the separation box 5. An insertion rod 17 is fixedly installed on the upper surface of the connecting frame 4. The insertion rod 17 is inserted into the insertion slot 16, and a positioning hole 18 is opened on the surface of the insertion rod 17. Positioning screws 19 are threadedly connected to both the front and rear sides of the separation box 5. The positioning screws 19 are inserted into the positioning holes 18.

[0040] The separation box 5 and the connecting frame 4 are detachably connected, and a locking component is provided. The positioning screw 19 is locked and positioned by being inserted into the positioning hole 18. This makes it easy to disassemble and replace the separation box 5, thereby enabling the quick replacement of filter screens 6 with different mesh sizes and the purpose of removing the separation box 5 to pour out the tea leaves, thus improving the flexibility and practicality of the device.

[0041] The connecting frame 4 is movably connected to the chassis 1. There are three separation boxes 5 on the surface of the connecting frame 4. The mesh size of the filter plate 6 inside each separation box 5 is different. The side wall of the chassis 1 has a window for the connecting frame 4 and the separation box 5 to move. An adjustment component is provided between the chassis 1 and the separation box 5.

[0042] The adjustment assembly includes built-in slots on the front and rear sides of the connecting frame 4. A limiting slide rod 7 is fixedly installed on the inner wall of the built-in slot. A fixed seat 8 is fixedly installed on the inner wall of the housing 1. The limiting slide rod 7 is slidably connected to the fixed seat 8. A straight rack 9 is fixedly installed at the bottom of the connecting frame 4. A drive motor 10 is fixedly installed on the right side of the housing 1. A gear plate 11 is fixedly installed on the surface of the output shaft of the drive motor 10. The gear plate 11 and the straight rack 9 mesh with each other.

[0043] It is worth noting that during the separation of tea leaves and tea dust, by setting an adjustment component, under the support and limiting effect of the limiting slide rod 7 on the connecting frame 4, the drive motor 10 drives the gear plate 11 to rotate. Based on the meshing of the gear plate 11 with the straight rack 9, the connecting frame 4 can be moved left and right, so as to achieve the purpose of switching and adjusting the separation box 5 together with the filter screen 6. This achieves the effect of quickly switching and adjusting the filter screen 6 with different mesh sizes, meeting the needs of separating different varieties of tea leaves and tea dust.
