Description

Technical Field

[0001] This utility model relates to the field of jasmine tea screening technology, specifically a jasmine tea leaf grading and screening device. Background Technology

[0002] Jasmine tea base is the core base tea in the jasmine tea scenting process. It refers to raw tea or refined tea that has been processed through specific primary and secondary processing techniques and has excellent aroma absorption capabilities. Currently, most jasmine tea bases need to be screened during production.

[0003] Most current screening equipment is an integrated design, which makes it difficult to quickly unload the jasmine tea leaves after the screening operation, affecting production efficiency. Therefore, we propose a jasmine tea leaf grading and screening device. Utility Model Content

A limiting rod is fixedly connected to one side, with one side of the limiting rod abutting against the surfaces of the first and second trays. Four symmetrically arranged rubber support legs are fixedly connected to the lower surface of the machine body, and a vibration motor is installed on the lower surface of the machine body. Two symmetrically arranged pads are fixedly connected to the bottom of the machine body. The coarse screen of the first tray and the fine screen of the second tray form a clear particle size classification. With the help of the vibration motor, the tea leaves are dispersed and tumbled, ensuring accurate separation of tea leaves of different particle sizes. Through the partition design of the first and second partitions, the hopper and the tray are divided into two independent areas, which can process two different specifications of tea leaves at the same time without batch screening, effectively improving the screening equipment. After screening, the material can be discharged quickly, which is suitable for the batch screening needs of large-scale jasmine tea production.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] refer to Figures 1-5 The jasmine tea blank grading and screening device shown includes a body 1, a hopper 2 fixedly connected to the upper surface of the body 1, and a screening component 3 inside the body 1. The screening component 3 includes two sets of placement slots 31, both sets of which are located on the inner wall of the body 1. Limiting slots 32 are formed on the inner wall of each placement slot 31. A first tray 33 and a second tray 34 are respectively inserted into the two placement slots 31. Limiting strips 35 are fixedly connected to both sides of the first tray 33 and the second tray 34, and the limiting strips 35 are adapted to the limiting slots 32. The sieve holes at the bottom of the first tray 33 are larger than those at the bottom of the second tray 34. A guide frame 39 is fixedly connected to the surface of the hopper 2, and a collar 37 is slidably connected to the guide frame 39. A limiting rod 310 is fixedly connected to one side of the collar 37. One side of the positioning rod 310 abuts against the surface of the first tray 33 and the second tray 34. Four symmetrically arranged rubber support legs 314 are fixedly connected to the lower surface of the machine body 1. A vibration motor 316 is installed on the lower surface of the machine body 1. Two symmetrically arranged pads 315 are fixedly connected to the bottom of the machine body 1. The coarse screen of the first tray 33 and the fine screen of the second tray 34 form a clear particle size classification. With the help of the vibration motor 316, the tea leaves are dispersed and tumbled to ensure accurate separation of tea leaves of different particle sizes. Through the partition design of the first partition 41 and the second partition 46, the hopper 2 and the tray are divided into two independent areas, which can process two different specifications of tea leaves at the same time without batch screening, effectively improving the screening equipment. After screening, the material can be discharged quickly, which is suitable for the batch screening needs of large-scale jasmine tea production.

[0019] The inner wall of the collar 37 is threaded with a bolt 38. One end of the bolt 38 abuts against the surface of the guide frame 39. Tightening the bolt 38 can complete the positioning of the limit rod 310.

[0020] The limiting rod 310 is bent, and a pull block 317 is fixedly connected to the surface of the limiting rod 310. A slide bar 312 is slidably connected to the lower end of the limiting rod 310. A baffle 311 is fixedly connected to one side of the slide bar 312 and is inserted into the bottom of the machine body 1.

[0021] The inner wall of the hopper 2 is fixedly connected with a net 313, and the surfaces of the first tray 33 and the second tray 34 are both fixedly connected with handles 36. Pulling the handles 36 can effectively remove the first tray 33 and the second tray 34.

[0022] The first tray 33 is equipped with a separator component 4 for separating the screened materials.

[0023] The separating component 4 includes two symmetrical first guide rods 42 fixedly connected to the inner walls of the first tray 33 and the second tray 34. A first partition 41 is slidably connected to the first guide rod 42. Two symmetrically arranged second guide rods 45 are fixedly connected to the hopper 2. A second partition 46 is slidably connected to the second guide rod 45. The rubber support leg 314 ensures the stability of the machine body 1 and buffers the vibration impact, preventing the tea leaves from falling due to shaking of the equipment during screening. The first tray 33 and the second tray 34 are precisely matched with the placement groove 31 through the limiting strip 35, so there is no deviation or jamming during vibration. The screen 313 intercepts large impurities to prevent the screen holes from being blocked. At the same time, all structures in contact with the tea leaves are free from rigid scraping, preserving the integrity of the tea leaves to the greatest extent.

[0024] Among them, two symmetrically arranged first locking blocks 43 are fixedly connected to one side of the limiting rod 310. The two first locking blocks 43 are respectively sleeved on the two first partitions 41. The upper end of the limiting rod 310 is fixedly connected to a second locking block 44, which is sleeved on the second partition 46. The positions of the first partition 41 and the second partition 46 can be freely adjusted by the limiting rod 310 and the collar 37. The partition size and screening standards can be flexibly adjusted according to different tea blank specifications or screening requirements. The tray and the baffle 311 can be quickly pulled out, making material collection and non-conforming product cleaning convenient without complicated disassembly, thus reducing the operating threshold.

[0025] The working principle of this utility model is as follows: Four rubber support legs 314 provide stable support for the machine body 1 and buffer the impact force of the vibration motor 316 during operation. Before the equipment is put into operation, the first tray 33 and the second tray 34 are inserted into the placement groove 31 on the inner wall of the machine body 1 through the limit strips 35 on both sides. The screen holes of the first tray 33 are larger than those of the second tray 34, forming a two-stage screening structure. Then, the first partition 41 and the second partition 46 are pulled to one side, and the first locking block 43 on the limit rod 310 is fastened to the first partition 41 and the second locking block 44 is fitted onto the second partition 46. The pull block 317 is pushed to drive the limit rod 310 to slide along the guide frame 39. The position of the first partition 41 in the first tray 33 and the second partition 46 in the hopper 2 are adjusted so that the two separate the tray and the hopper 2 into two independent areas. The bolts 38 on the collar 37 are tightened to press against the guide frame 39 to complete the partition fixation and realize the dual-specification screening structure. At the same time, the baffle 311 is inserted into the bottom of the machine body 1 to temporarily store unqualified materials.

[0026] The jasmine tea blanks to be screened are put into the hopper 2. The mesh 313 on the inner wall of the hopper 2 first filters the tea blanks to intercept large impurities or clumps of tea blanks, so as to avoid clogging the subsequent sieve holes. The second partition 46 in the hopper 2 divides the tea blanks after preliminary screening into two parts and guides them to the two partition areas of the first tray 33 respectively, so as to realize the synchronous feeding of two specifications of materials. Start the vibration motor 316 on the lower surface of the machine body 1. The vibration is transmitted through the machine body 1 to the first tray 33 and the second tray 34. The vibration force causes the tea leaves to disperse and tumble in the trays. In the first tray 33, tea leaves with a particle size larger than the sieve hole are retained as the first-level qualified material. Tea leaves with a particle size smaller than the sieve hole and some fine material pass through the sieve hole and fall into the second tray 34 below. Tea leaves that meet the preset particle size are retained as the second-level qualified material. Tea leaves or fragments with an excessively small particle size pass through the sieve hole and fall into the bottom of the machine body 1 as unqualified material, thus completing the screening operation. After screening, turn off the vibration motor 316, loosen the bolt 38 and pull the pull block 317 to move the limit rod 310, the first locking block 43 and the second locking block 44, and release the fixation of the first partition 41 and the second partition 46. The first tray 33 and the second tray 34 can be pulled out by the handle 36 respectively to collect qualified tea leaves of different specifications in the two trays. Pull out the baffle 311 to clean the unqualified materials at the bottom of the machine body 1 and complete one screening cycle.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.
