Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea grinding and feeding technology, specifically a tea grinding device for processing tea powder that facilitates feeding. Background Technology
[0002] In the tea powder processing industry, tea grinding equipment is a key device for converting tea leaves into tea powder. Before entering the grinding equipment for processing, the tea leaves need to be transported to the grinding area through a feeding process. However, existing tea grinding equipment generally has some shortcomings in the feeding process.
[0003] Tea leaves have a certain degree of adsorption and flexibility, and they are prone to tangling and piling up in the feed hopper, forming bridging and blockage structures. This prevents the tea leaves from sliding down smoothly, resulting in interrupted or uneven feeding, which seriously affects the working efficiency of the grinding device and the continuity of tea powder processing. Although some grinding devices use a single gravity feeding or simple mechanical conveying method, these methods cannot effectively solve the problem of tea leaves accumulating and blocking at the feed inlet, resulting in poor feeding effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tea grinding device for tea powder processing that facilitates feeding.

When the motor drives the rotating shaft to rotate, the pulley assembly fixedly connected to the rotating shaft also rotates. Since the outer wall of the rotating rod is fixedly connected to the inner wall of the pulley assembly on the side away from the rotating shaft, the pulley assembly will drive the rotating rod to rotate along the support block.
[0012] Preferably, a discharge pipe is fixedly connected to the inner wall of the bottom of the grinder, and the ground tea powder is discharged through the discharge pipe fixedly connected to the inner wall of the bottom of the grinder.

[0024] 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.
[0025] Please see Figure 1-5 This utility model provides a technical solution: a tea grinding device for processing tea powder that facilitates feeding, comprising: a grinder 1, a feeding pipe 2 fixedly connected to the outer wall of the top of the grinder 1, a conveying device 3 fixedly connected to the inner wall of the feeding pipe 2, and a feeding structure 4, the outer wall of the feeding structure 4 being fixedly connected to the inner wall of the conveying device 3; the feeding structure 4 includes a feeding hopper 41, a support base 411 fixedly connected to the outer wall of the bottom of the feeding hopper 41, a sliding rod 42 symmetrically fixedly connected to the outer wall of the side of the feeding hopper 41, a sliding plate 43 slidably connected to the outer wall of the sliding rod 42, a striking block 44 fixedly connected to the outer wall of the sliding plate 43, a compression spring 45 symmetrically fixedly connected to the outer wall of the sliding plate 43 away from the striking block 44, a baffle 47 fixedly connected to the outer wall of the sliding rod 42, a rotating rod 48 rotatably connected to the inner wall of the side of the feeding hopper 41, and a cam 49 symmetrically fixedly connected to the outer wall of the rotating rod 48.
[0026] The outer wall of cam 49 contacts the outer wall of slide plate 43. The outer wall of compression spring 45 on the side away from slide plate 43 is fixedly connected to the outer wall of baffle 47. The outer wall of striking block 44 contacts the outer wall of side of feed hopper 41. When rotating rod 48 rotates, it will drive cam 49 to rotate. Its outer wall contacts the outer wall of slide plate 43 and pushes slide plate 43 to slide on slide rod 42. When slide plate 43 slides, it will move closer to baffle 47 and compress compression spring 45. When cam 49 rotates to a certain position and no longer contacts slide plate 43, compression spring 45 restores elastic deformation and pushes slide plate 43 to slide in the opposite direction, so that striking block 44 on slide plate 43 strikes the outer wall of side of feed hopper 41. The tea leaves in feed hopper 41 are loosened by striking vibration to prevent tea leaves from accumulating.
[0027] The conveying device 3 includes a conveying cylinder 31, an inlet 32 on the outer wall of the conveying cylinder 31, a conveying screw 33 rotatably connected to the inner wall of the conveying cylinder 31, a rotating shaft 34 fixedly connected to the outer wall of the conveying screw 33, a pulley set 35 fixedly connected to the outer wall of the rotating shaft 34, a support block 36 fixedly connected to the outer wall of the conveying cylinder 31, and a motor 37 rotatably connected to the outer wall of the rotating shaft 34.
[0028] The inner wall of the support base 411 is fixedly connected to the outer wall of the conveying cylinder 31 and the motor 37. The outer wall of the bottom of the feed hopper 41 is fixedly connected to the inner wall of the feed inlet 32. The outer wall of the rotating rod 48 is rotatably connected to the inner wall of the support block 36. The outer wall of the rotating rod 48 is fixedly connected to the inner wall of the pulley assembly 35 on the side away from the rotating shaft 34. When the motor 37 drives the rotating shaft 34 to rotate, the pulley assembly 35 fixedly connected to the rotating shaft 34 also rotates. Since the outer wall of the rotating rod 48 is fixedly connected to the inner wall of the pulley assembly 35 on the side away from the rotating shaft 34, the pulley assembly 35 will drive the rotating rod 48 to rotate along the support block 36.
[0029] A discharge pipe 11 is fixedly connected to the inner wall of the bottom of the grinder 1. The ground tea powder is discharged through the discharge pipe 11 fixedly connected to the inner wall of the bottom of the grinder 1. A support plate 12 is fixedly connected to the outer wall of the side of the grinder 1.
[0030] The inner wall of the feed pipe 2 is fixedly connected to the outer wall of the conveying cylinder 31. The rotating conveying screw 33 conveys the tea leaves that enter the conveying cylinder 31 along the conveying cylinder 31 towards the feed pipe 2. Finally, the tea leaves enter the grinder 1 through the feed pipe 2 for grinding. The inner wall of the support plate 12 is fixedly connected to the outer wall of the conveying cylinder 31 to support the conveying cylinder 31 on the conveying device 3 and ensure the stability of the conveying.
[0031] When in use, the tea leaves to be ground are placed into the feeding structure 4, and then the tea leaves are sent into the grinder 1 from the feeding pipe 2 through the conveying device 3. The support plate 12 supports the conveying cylinder 31 on the conveying device 3 to ensure the stability of the conveying. The tea leaves entering the grinder 1 are ground into tea powder by the grinding components inside the grinder 1. The ground tea powder is discharged through the discharge pipe 11 fixedly connected to the bottom inner wall of the grinder 1.
[0032] First, the tea leaves to be ground are placed into the feed hopper 41. The support base 411 provides stable support for the feed hopper 41. Then, the motor 37 is started. The rotation of the motor 37 drives the rotating shaft 34 to rotate. The rotation of the rotating shaft 34 will drive the conveying screw 33, which is fixedly connected to it, to rotate inside the conveying cylinder 31. The outer wall of the bottom of the feed hopper 41 is fixedly connected to the inner wall of the feed port 32 on the conveying cylinder 31. The tea leaves falling from the feed hopper 41 enter the conveying cylinder 31 through the feed port 32. The rotating conveying screw 33 conveys the tea leaves that have entered the conveying cylinder 31 along the conveying cylinder 31 towards the feed pipe 2. Finally, the tea leaves enter the grinder 1 through the feed pipe 2 for grinding.
[0033] Tea leaves in the feed hopper 41 may experience bridging or blockage due to accumulation, hindering feeding. As the motor 37 drives the rotating shaft 34 to rotate, the pulley assembly 35 fixedly connected to the shaft 34 also rotates. Since the outer wall of the rotating rod 48 is fixedly connected to the inner wall of the pulley assembly 35 on the side away from the shaft 34, the pulley assembly 35 drives the rotating rod 48 to rotate along the support block 36. The cams 49 symmetrically fixedly connected to the rotating rod 48 rotate together with the rotating rod 48. During rotation, the outer... The wall contacts the outer wall of the slide plate 43 and pushes the slide plate 43 to slide on the slide rod 42. When the slide plate 43 slides, it will move closer to the baffle 47 and compress the compression spring 45. When the cam 49 rotates to a certain position and no longer contacts the slide plate 43, the compression spring 45 restores its elastic deformation and pushes the slide plate 43 to slide in the opposite direction, so that the striking block 44 on the slide plate 43 strikes the outer wall of the side of the feed hopper 41. The tea leaves in the feed hopper 41 are loosened by the striking vibration, preventing the tea leaves from accumulating and promoting the smooth feeding of the tea leaves.
