Description

Technical Field

[0001] This utility model belongs to the technical field of tea grinding machines, and in particular relates to a feeding auxiliary device for a tea grinding machine. Background Technology

[0002] Traditional tea grinders often suffer from uneven feeding during the tea grinding process, leading to material accumulation or idling within the grinding chamber, which affects grinding efficiency and the consistency of the finished product particle size. Current technologies mostly employ gravity-fed inlets, making it difficult to achieve uniform material dispersion and continuous conveying. Furthermore, the blade gap adjustment mechanism largely relies on manual operation, resulting in low precision and poor adjustment efficiency, failing to adapt to the grinding needs of different tea varieties.

[0003] Therefore, there is an urgent need for a feeding auxiliary device for tea grinders that can achieve uniform feeding, material distribution, and dynamic adjustment of the blade gap. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding auxiliary device for tea grinders to solve the problems of common tea grinders, such as difficulty in achieving uniform dispersion and continuous conveying of materials, easy clumping of tea leaves blocking the conveying, and low precision and poor adjustment efficiency of the blade gap.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a feed inlet, a grinding chamber, and a brushless motor. A discharge pipe is installed on one side of the grinding chamber. An upper cutter disc and a lower cutter disc are provided inside the grinding chamber to form a cutter disc assembly. An upper cutter holder and a lower cutter holder are installed at the top and bottom of the cutter disc assembly. The lower cutter holder is connected to the brushless motor. The upper cutter holder is embedded in the top cover of the grinding chamber and slidably connected. A feeding rod is vertically provided in the middle of the feed inlet. A spiral guide blade is fixed on the outer surface of the feeding rod. A material distribution blade is provided at the top of the feeding rod and fixed with screws. A cutter disc adjustment mechanism is provided on the outside of the grinding chamber.

[0006] Furthermore, the bottom of the feeding rod is connected to the top of the output end of the brushless motor, the outer diameter of the guide blade does not exceed half of the inner diameter at the minimum point of the feed inlet, and the outer diameter of the distributing blade does not exceed the inner diameter at the maximum point of the feed inlet.

[0007] Furthermore, the outer diameter of the guide vane is limited to less than 50% of the minimum inner diameter of the feed inlet to ensure that there is a gap between the material and the inner wall of the feed pipe, reduce frictional resistance, and form a laminar flow distribution that is "dense in the center and loose in the periphery".

[0008] Furthermore, the blade adjustment mechanism includes a servo motor and a transmission screw. The servo motor and the transmission screw are driven by gears. The transmission screw is connected to the grinding chamber through a bracket and a rotating shaft. The servo motor is connected to the grinding chamber through a bracket and screws.

[0009] Furthermore, a pressure ring block is movably provided on the top of the upper cutter disc, and the pressure ring block is connected to the outer wall of the feed port. A gear disc is provided above the grinding chamber, and the gear disc is connected to the outer wall of the feed port. The gear disc and the transmission screw are connected by external teeth and threads.

[0010] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0011] In this invention, the spiral guide blades allow the material to fall evenly under the action of gravity and rotational force, avoiding blockage of the feed inlet. The design of the separating blades can break up the tea leaves that have formed bridges in the tea storage, allowing the tea leaves to fall normally into the feed inlet instead of being squeezed and fixed in the tea storage, thereby achieving efficient feeding and preventing blockage.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Combination Figures 1 to 3 The shown is a feeding auxiliary device for a tea grinder, including a feeding inlet 1, a grinding chamber 2, and a brushless motor 3. A discharge pipe is installed on one side of the grinding chamber 2. An upper cutter disc and a lower cutter disc are provided inside the grinding chamber 2 to form a cutter disc assembly. An upper cutter holder and a lower cutter holder are installed at the top and bottom of the cutter disc assembly. The lower cutter holder is connected to the brushless motor 3. The upper cutter holder is embedded in the top cover of the grinding chamber 2 and is slidably connected. A feeding rod 4 is vertically provided in the middle of the feeding inlet 1. A spiral guide blade 41 is fixed on the outer surface of the feeding rod 4. A distributing blade 42 is provided on the top of the feeding rod 4 and is fixed by screws. A cutter disc adjustment mechanism 5 is provided on the outside of the grinding chamber 2.

[0019] Among them, the bottom of the feeding rod 4 is connected to the top of the output end of the brushless motor 3, the outer diameter of the guide blade 41 does not exceed half of the inner diameter of the smallest point of the feed inlet 1, and the outer diameter of the distributing blade 42 does not exceed the inner diameter of the largest point of the feed inlet 1.

[0020] The tool head adjustment mechanism 5 includes a servo motor 51 and a transmission screw 52. The servo motor 51 and the transmission screw 52 are driven by gears. The transmission screw 52 is connected to the grinding chamber 2 through a bracket and a rotating shaft.

[0021] A pressure ring block 53 is movably provided on the top of the upper cutter head. The pressure ring block 53 is connected to the outer tube wall of the feed port 1. A gear disk 54 is provided above the grinding chamber 2. The gear disk 54 is connected to the outer tube wall of the feed port 1. The gear disk 54 and the transmission screw 52 are connected by external teeth and thread meshing.

[0022] Working Principle: In use, tea leaves enter through the feed inlet 1 and reach the distributing blades 42 at the top of the feeding rod 4. The distributing blades, driven by the radial dispersion force generated by the rotation of the feeding rod 4, actively break up any clumps of tea leaves. The spiral guide blades 41 on the outer surface of the feeding rod 4 rotate with the brushless motor 3, generating a downward spiral thrust. Under the combined action of gravity and centrifugal force, the material moves evenly downward along the spiral trajectory of the guide blades 41, avoiding local accumulation. The tea powder, after being pulverized by the cutter head assembly, is thrown towards the inner wall of the grinding chamber 2 under centrifugal force and discharged through the side discharge pipe. The cutter head adjustment mechanism 5 drives the transmission screw 52 to rotate via the servo motor 51. The gear disc 54 engages with the threaded drive screw, converting the rotational motion into the axial displacement of the pressure ring block 53. The pressure ring block 53 compresses the upper cutter head to move axially along the grinding chamber, thereby dynamically adjusting the gap between the upper and lower cutter heads.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
