Description

Technical Field

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

[0002] Scented tea, also known as scented tea, is tea made from the flowers, leaves or fruits of plants. It is a type of reprocessed tea unique to China. It takes advantage of the fact that tea is good at absorbing odors. Fresh flowers with fragrance are stewed together with new tea. After the tea absorbs the fragrance, the dried flowers are sieved out. The scented tea made is rich in fragrance and has a dark tea soup. Scented tea is mainly made of green tea, black tea or oolong tea as the tea base, and fresh flowers that can emit fragrance as raw materials. It is made by scenting technology. In the process of scented tea production, screening devices are often used. For example, screening devices are used to sieve out some broken tea and tea scraps to avoid affecting the quality of the finished product after the scented tea is packaged.

[0003] In the prior art, the screening effect of the scented tea screening device is not ideal. Before screening, the scented tea clumps often need to be manually broken up and then spread flat on the screening device for screening. The operation is complicated, labor is wasted, and the production efficiency of the scented tea is reduced. Utility Model Content

[0004] In view of the above problems, the utility model provides a screening device for scented tea production to solve the problem in the prior art that the production efficiency of scented tea is reduced due to cumbersome operation.

[0005] The utility model is realized by using the following technical scheme: a screening device for scented tea production, comprising a frame and a sieve plate, a bulk bin is fixedly mounted on the frame, a roller penetrating the bulk bin is rotatably mounted in the bulk bin, the roller is located in the bulk bin, and a plurality of bulk teeth for breaking up materials are mounted on the roller; a feed port and a discharge port are also provided on the bulk bin, and the discharge port of the bulk bin is located above the sieve plate; a motor is also fixedly mounted on the frame, and the output shaft of the motor is drivingly connected to the roller.

[0006] By setting up the bulk bin, the scented tea will be broken up before entering the screen plate for screening, thereby increasing the quality and efficiency of scented tea screening; at the same time, compared with manual breaking up, mechanical breaking up saves labor and increases the breaking up efficiency, further improving the efficiency of scented tea production.

[0007] Preferably, an inclined buffer plate is fixedly mounted on the left side of the sieve plate, and the discharge port is located directly above the buffer plate. The buffer plate is used to buffer the scattered scented tea, preventing the scented tea from rushing vertically toward the sieve plate directly after being scattered, and preventing the scented tea from being damaged by the sieve plate.

[0008] Preferably, a mounting plate is fixedly mounted on the frame, a fixing block is fixedly mounted on the mounting plate, the left side of the fixing block is fixedly connected to the right end of a spring, the left end of the spring is fixedly connected to a push block, the top of the push block is fixedly connected to the bottom of the buffer plate, and the push block is slidably matched with the mounting plate; the motor is connected to a rotating shaft, the rotating shaft is rotatably arranged on the frame, a cam is fixedly mounted on the rotating shaft, and the cam abuts against the push block. Through the arrangement of the cam and the spring, the sieve plate can move left and right under the drive of the motor, thereby realizing the screening function. In addition, the design of the mounting plate and the push block can also support the buffer plate and the sieve plate, making them more stable during movement.

[0009] Preferably, an active single-groove pulley is fixedly connected to the output shaft of the motor, a double-groove pulley is fixedly installed at one end of the rotating shaft close to the motor, and the active single-groove pulley and the double-groove pulley are connected through a second belt transmission.

[0010] Preferably, a driven single-groove pulley is fixedly mounted on one end of the roller close to the motor, and the driven single-groove pulley is connected to the double-groove pulley through a first belt transmission. The driven single-groove pulley is connected to the double-groove pulley so that the roller will rotate synchronously when the shaft rotates, thereby increasing the synchronization of the mechanical operation of the device and eliminating the need to add a separate motor control, thereby saving space and the number of motors.

[0011] Preferably, a residual material bin is installed below the sieve plate, and the front and rear sides of the residual material bin extend upward to form a limit plate, and the sieve plate is located between the two limit plates and slidably cooperates with the limit plates. By setting the residual material bin, the screened broken tea can be stored to protect the environment or facilitate the secondary use of the broken tea.

[0012] Preferably, the inner sides of the two limiting plates are provided with limiting grooves, and the front and rear sides of the sieve plate are provided with limiting blocks adapted to the limiting grooves, and the limiting grooves and the limiting blocks are slidably matched.

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0024] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0025] like Figure 1 , Figure 4 As shown, the utility model provides a screening device for scented tea production, including a frame 6 for installing the device and a sieve plate 22 for screening. A bulk bin 4 for breaking up the scented tea is installed on the top of the frame 6, and a feed port 5 is provided on the bulk bin 4. A discharge port 1 is provided below the bulk bin 4, and the discharge port 1 is located on the top of the sieve plate 22. A roller 26 that penetrates the bulk bin 4 horizontally is rotatably installed inside the bulk bin 4, and a plurality of bulk teeth 25 for breaking up the scented tea are fixedly installed on the roller 26. A motor 14 is also fixedly installed at the bottom of the frame 6, and the output shaft of the motor 14 is connected to the roller 26 through a first transmission mechanism, thereby driving the rotation of the roller 26.

[0026] like Figure 1 , Figure 2 As shown, a buffer plate 7 is fixedly installed on the left side of the sieve plate 22 in the present device, and the discharge port 1 of the bulk bin 4 is located directly above the buffer plate 7, and the buffer plate 7 is tilted downward from left to right. The buffer plate 7 is mainly used to buffer the scattered scented tea to prevent the scented tea from directly rushing toward the sieve plate 22 in the vertical direction after being scattered, and thus being damaged by the sieve plate 22. By adding a buffer plate 7, and the position of the buffer plate 7 close to the discharge port 1 is higher than the position close to the sieve plate 22, the force on the scattered scented tea falling on the buffer plate 7 is smaller than the force on the sieve plate 22 directly; after being scattered, the scented tea first falls on the buffer plate 7, and then slides downward under the shaking of the buffer plate 7, so that the scented tea moves smoothly to the sieve plate 22.

[0027] like Figure 1 , Figure 2 As shown, a mounting plate 15 is fixedly installed in the middle of the frame 6, and a fixed block 17 is also installed on the mounting plate 15. The left side of the fixed block 17 is fixedly connected to the right end of the spring 16, and the left end of the spring 16 is fixedly connected to the push block 8. The top of the push block 8 is fixedly connected to the bottom of the buffer plate 7, and the bottom of the push block 8 is slidably matched with the upper surface of the mounting plate 15. Specifically, a slider is provided at the bottom of the push block 8, and a slide groove adapted to the slider is provided on the upper surface of the mounting plate 15. The slider and the slide groove are matched. The sliding match here belongs to the prior art and will not be described in detail here. A rotating shaft 9 is also rotatably provided in the middle of the left side of the frame 6. The end of the rotating shaft 9 close to the motor 14 is connected to the output shaft of the motor 14 through a second transmission mechanism. A cam 10 is also fixedly installed in the middle of the rotating shaft 9, and the cam 10 abuts against the push block 8. The motor 14 drives the cam 10 to rotate, and the rotation of the cam 10 cooperates with the spring 16 to enable the push block 8 to slide left and right, thereby driving the screen plate 22 to move left and right, thereby realizing the screening function.

[0028] The first transmission mechanism mentioned above mainly includes a driven single-groove pulley 2, which is connected to the double-groove pulley 11 through a first belt 3. By connecting the double-groove pulley 11 to the driven single-groove pulley 2, the operation of the bulk bin 4 no longer requires an additional motor 14, which saves space and ensures the coordination of mechanical operation. The second transmission mechanism mainly includes an active single-groove pulley 13 coaxially fixedly connected to the output shaft of the motor 14, and a double-groove pulley 11 is coaxially fixedly connected to one end of the rotating shaft 9 close to the active single-groove pulley 13. The active single-groove pulley 13 and the double-groove pulley 11 are connected through a second belt 12. The transmission connection of the pulley makes the installation position of the motor 14 more flexible, so that the motor 14 can be installed in a more convenient and safe position.

[0029] like Figure 1 , Figure 2 As shown, baffles 21 are fixedly installed on the front and rear sides of the sieve plate 19, the front and rear sides of the buffer plate 7, and the left side of the buffer plate 7. The setting of the baffle 21 can prevent the scented tea from being shaken out during the movement of the sieve plate 22 and the baffle 21, thereby causing waste and environmental impact.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, a residual material bin 19 for storing the sieved broken tea, tea scraps and other debris is also installed below the sieve plate 22, and a material taking door 18 for taking out the broken tea in the residual material bin 19 is also provided on one side of the residual material bin 19. The front and rear sides of the residual material bin 19 extend upward to form a limit plate 20, and the sieve plate 22 is located between the two limit plates 20 and slides with the limit plates 20; specifically, a limit groove 24 is provided on one side of the two limit plates 20 close to each other, and a limit block 23 adapted to the limit groove 24 is provided on the front and rear sides of the sieve plate 22, and the limit groove 24 slides with the limit block 23. Through the design of the limit block 23 and the limit groove 24, the bulk material bin 4 can play a supporting role on the sieve plate 22, and the bulk material bin 4 and the push block 8 jointly support and guide the sieve plate 22, so that the device can be more stable during operation, further increasing the service life of the device.

[0031] In addition, the size of the opening at the top of the residual material bin 19 can ensure that when the screen plate 22 moves, all the broken tea leaves that have been screened can fall into the residual material bin 19, and a discharge plate 27 that is inclined downward from left to right is provided at the end of the screen plate 22 away from the buffer plate 7. The discharge plate 27 is integrally formed with the screen plate 22, and the discharge plate 27 will not fall within the range of the residual material bin 19, that is, the screened scented tea will not fall into the residual material bin 19. After the scented tea is screened, it will follow the inclined surface on the screen plate 22 to enter the next process or enter a storage device for storage, such as directly above the conveyor belt, or a storage tank is installed below it.

[0032] The operating principle of the device is as follows: when it is necessary to screen the scented tea, first turn on the motor 14 and pour the scented tea from the feed port 5 of the bulk bin 4. Some sticky scented tea will be broken up when entering the bulk bin 4, and then fall onto the buffer plate 7 through the discharge port 1. When falling onto the buffer plate 7, the scented tea will move toward the sieve plate 22 due to the inclination and movement of the buffer plate 7, and will be further dispersed during the movement due to the shaking of the buffer plate 7. The broken tea in the scented tea that reaches the sieve plate 22 will pass through the sieve holes on the sieve plate 22 and fall into the residual bin 19. The scented tea that has been screened will go along the sieve plate 22 to the next process or be stored.

[0033] In summary, the screening device for scented tea production provided by the utility model has a bulk bin 4 for breaking up the scented tea installed on the top of the sieve plate 22, thereby preventing insufficient screening and poor screening quality caused by part of the scented tea sticking together during the screening process, and also saves labor time through direct mechanical breaking up, further improving the efficiency of scented tea production.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
