Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a material unloading device for the production and processing of Pu'er tea cakes. Background Technology

[0002] As a typical representative of traditional compressed tea, Pu'er tea cakes are undergoing a critical transformation from manual workshops to industrialization and intelligentization in their production process. The unloading process, as the hub connecting pressing and subsequent processes, directly affects the efficiency and cost of the entire production line due to the level of intelligence of its equipment. Currently, manual sorting or simple mechanical devices are mostly used to complete the unloading process of tea cakes.

[0003] However, existing unloading devices still have many shortcomings. Traditional unloading devices are too simple in function, only having the function of conveying. They cannot screen and grade tea cakes, and it is difficult to effectively remove tea leaves that are not compressed on the surface of the tea cakes, which affects the appearance quality of the tea cakes and the efficiency of subsequent packaging. Loose tea leaves are easy to absorb moisture from the air, which can also cause the tea cakes to become damp and moldy in some areas, affecting the shelf life.

[0004] Therefore, those skilled in the art have provided a material unloading device for the production and processing of Pu'er tea cakes to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problem that traditional unloading devices cannot remove loose tea leaves from the surface of tea cakes and thus cannot grade them, this invention provides a solution based on an unloading device for Pu'er tea cake production and processing, employing the following technical solution:

[0006] A material unloading device for processing Pu'er tea cakes includes a receiving platform, a feeding platform fixedly connected to one side of the receiving platform, a shaking sieve mechanism fixedly connected to one side of the feeding platform, a material distributing mechanism movably connected to the inner cavity of the feeding platform, and a housing including a box body. One side of the box body is fixedly connected to the feeding platform, and a shell is fixedly connected to the top of the box body. A first motor is fixedly connected to one side of the inner cavity of the shell, a worm gear is fixedly connected to the output end of the first motor, a worm wheel meshes with the bottom of the worm gear, a rotating rod is fixedly connected to the inner cavity of the worm wheel, and cams are fixedly connected to both sides of the rotating rod, penetrating the inner cavity of the shell. A sieve plate is movably connected to the inner cavity of the box, and both sides of the sieve plate penetrate the inner cavity of the box and are fixed. The device is equipped with a cam that works in conjunction with the cam. Springs are installed on both sides of the bottom of the sieve plate, and the bottom of the springs is fixedly connected to the housing. A control board is installed on one side of the receiving platform to control the start and stop of the entire device, making the operation of the device simpler and easier for the staff to learn. A conveyor belt is installed on the top of the receiving platform to transport the tea cake to the feeding platform. A maintenance door is hinged on the top of the housing to facilitate the maintenance or replacement of the first motor. Both sides of the rotating rod are movably connected to the housing through bearings. A connecting rod is connected to the top of the cam through bolts and threads. The top of the connecting rod is fixedly connected to the rotating rod, allowing the staff to adjust the vibration amplitude of the shaking sieve mechanism according to their needs to adapt to different types of tea cakes.

[0007] Optionally, the material separating mechanism includes a second motor, one side of which is fixedly connected to the feeding table. A lead screw is fixedly connected to the output end of the second motor, and a threaded sleeve is threaded onto the surface of the lead screw. A toothed plate is fixedly connected to one side of the threaded sleeve. The top of the toothed plate is movably connected to the feeding table. Gears mesh on both sides of the toothed plate. A movable rod is fixedly connected to the inner cavity of the gear. The bottom of the movable rod passes through the inner cavity of the gear and is movably connected to the feeding table through a bearing. The top of the movable rod passes through the inner cavity of the feeding table and is fixedly connected to a separating plate. There are two gears and two separating plates, which enables the material separating mechanism to distinguish products of different sizes. A rubber pad is provided on one side of the separating plate, which can effectively reduce the impact force on the tea cake caused by collision and prevent the tea leaves on the tea cake from falling onto the feeding table, thus increasing the difficulty of cleaning the feeding table later.

[0008] Optionally, a detection door is fixedly connected to one side of the receiving platform, and a vision sensor is fixedly connected to the top of the detection door. The detection door is located between the receiving platform and the feeding platform, and the other side of the detection door is fixedly connected to the feeding platform. When the tea cake passes through the detection door, the top vision sensor will transmit information to the dispensing mechanism.

[0009] Optionally, a hinged door is provided on one side of the box, and a handle is fixedly connected to the surface of the hinged door. There are two hinged doors and two handles to facilitate the collection of tea cakes from the box by staff.

[0010] Optionally, a partition is fixedly connected to the inner cavity of the box, and one side of the partition is movably connected to a sieve plate. The partition divides the space inside the box to separate tea cakes of different sizes.

[0011] Optionally, a limiting block is fixedly connected to the top of the inner cavity of the feeding platform, a limiting groove is opened on the top of the toothed plate, and the bottom of the limiting block is slidably connected to the limiting groove. The setting of the limiting block and the limiting groove can restrict the movement mode of the toothed plate and prevent it from disengaging from the meshing point with the gear.

[0012] Optionally, a slider is fixedly connected to one side of the bottom of the material distribution plate, and a groove is provided on the surface of the feeding table. The bottom of the slider is slidably connected to the groove. The slider and the groove can limit the range of motion of the material distribution plate and prevent excessive movement from causing the tea cake to be unable to be transported into the box.

[0013] Optionally, a collection box is provided at the bottom of the sieve plate. The collection box is movably connected to the box body on both sides. There are two collection boxes, which are used to recycle the tea leaves that fall onto the sieve plate.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. This utility model, through a shaking and sieving mechanism, can efficiently remove loose tea leaves from tea cakes, preventing debris from adhering and making the surface of the tea cake smoother and the texture clearer, thus improving visual quality. It also avoids the problem that if uncompressed tea leaves are not shaken off in time, they may continue to fall off due to friction during packaging and transportation, polluting the packaging environment or causing defects on the surface of the tea cake. Furthermore, the accumulation of loose tea leaves is prone to mold growth or dust pollution. The shaking mechanism can reduce hygiene hazards on the production line, prevent debris from entering the transmission parts of the device, reduce the mechanical failure rate, and extend the service life of the device. The collection box allows the shaken tea leaves to be recycled and reused for blending or making tea bags and other by-products, reducing the loss of raw materials caused by direct waste.

[0016] 2. This utility model, through a sorting mechanism, can quickly classify tea cakes of different sizes, reducing the time and cost of manual sorting. It is especially suitable for large-scale production scenarios, solving the problem that if tea cakes of different sizes are mixed together during unloading, they are prone to edge damage due to collision or squeezing. It can ensure that the specifications of tea cakes in the same batch are uniform, improving the consistency of taste and aging potential. Large-sized tea cakes usually occupy a lot of space and need to be individually packaged or in special containers, while small-sized tea cakes are more portable. The sorting mechanism can classify and store tea cakes according to their specifications, which is convenient for subsequent packaging and logistics planning, and avoids low storage efficiency or transportation losses caused by size confusion.

[0031] The implementation principle of this utility model is as follows: In use, the external device transports the tea cake to the conveyor belt at the top of the receiving platform 1.

The toothed plate 404 drives the gear 405 to rotate. The gear 405 drives the distribution plate 407 to rotate. The two distribution plates 407 rotate simultaneously to block the other feeding port on the feeding platform 2. The system guides the tea cake into the corresponding feeding port, allowing it to enter the housing 301. Simultaneously, the first motor 303 starts, driving the worm gear 304 to rotate. The worm gear 304 then drives the worm wheel 305 to rotate, which in turn drives the rotating rod 306 to rotate. The rotating rod 306 then drives the cam 307 to rotate. When the cam 307 reaches the bottom, it presses down on the protrusion 309. The movement of the protrusion 309 moves the sieve plate 308. The sieve plate 308 automatically rebounds when the cam 307 disengages from the protrusion 309, relying on the force of the spring 310, completing the vibration screening. After screening, the staff opens the movable door 7 through the handle 8 to remove the tea cake and pulls out the collection box 14 to collect the tea leaves inside.
