Abstract
Description

[0002] The asymmetric double-helix conical mixer is a new type of high-efficiency, high-precision mixing equipment. This machine uses a single motor and cycloidal pinwheel reducer to achieve both revolution and rotation. Utilizing the principle of combining the rotary motion of long and short stirring screws with the rotational motion of the two screws, it achieves ideal mixing of materials with significantly different specific gravities, resulting in short mixing time and excellent mixing effect. It is widely applicable to the mixing of various powders in industries such as pharmaceuticals, food, chemicals, pesticides, feed, petroleum, metallurgy and mining, building materials, and coatings.
[0003] During operation, the cycloidal pinwheel reducer of an asymmetric double-helix conical mixer requires regular application of lithium-based grease to ensure its normal operating efficiency and prevent damage to internal components. Currently, the primary lubrication method for asymmetric double-helix conical mixers is manual lubrication, involving the periodic and quantitative application of lithium-based grease. However, manual lubrication is cumbersome, consuming significant manpower and resources, and the precision of grease application is difficult to control, hindering cost reduction. Therefore, an automatic lubrication system for the mixer is urgently needed to solve the internal lubrication problem. Utility Model Content

[0031] Example 1:
[0032] like Figure 1-4 The automatic lubrication component for a mixer according to this invention is described in detail below. The core of this embodiment lies in its three-level support structure: a bottom support layer, a motion transmission layer, and a lubrication execution layer. This structure enables a stable and reliable automatic lubrication function, with each component working in concert to ensure stable system operation even under mixer vibration conditions.
[0033] The bottom support layer provides a rigid foundation and drive function for the automatic lubrication components. The lower limit base plate 1 is horizontally fixed to the bottom of the mixer's inner wall with high-strength bolts, serving as the mounting base for the entire system. A lead screw 4 is embedded inside, with both ends of the lead screw 4 connected to the side wall of the base plate 1 via ball bearings to ensure uniform axial force. The drive motor 3 is fixed to the outside of the base plate 1 via a flange, with its output shaft coaxially connected to the lead screw 4, providing the power source for the system. The base plate 1 is made of 10mm thick Q235 steel plate with a flatness error ≤0.5mm, ensuring the stability of the upper structure's mounting reference and fundamentally preventing displacement deviations caused by mixer vibration.
[0034] The motion transmission layer provides vertical guidance and precise transmission for the automatic lubrication components. The inner support beam 2 is vertically welded to the center of the upper surface of the base plate 1. Its cross-section is I-shaped, with an internal sliding rail 5 featuring a dovetail groove design. The sliding rail 5, made of copper-based alloy, is fitted with the dovetail groove rail and engages with the lead screw 4 via a micro-gearbox. The I-beam structure increases the bending section modulus by 40%, preventing flexural deformation during lubrication component movement. Simultaneously, the dovetail groove rail and copper alloy slider design of the sliding rail 5 and sliding rail 6 ensure load-bearing strength while reducing friction loss through self-lubrication.
[0035] The lubrication execution layer provides modular oiling and dynamic sealing functions for the automatic lubrication components. The lubrication assembly 7 is locked to the slider 6 via a fixed slot 302. The fixed back plate 103 has transverse locking blocks 301 on both sides, which are fastened to the slots 302 with bolts, forming a bidirectional shear-resistant structure. The rear drive block 101 is connected to a pneumatic telescopic rod 102, which pushes the limiting guard plate 104 to lock into the pre-set positioning holes on the inner wall of the mixer, eliminating the effects of working vibration.
[0036] Two symmetrically arranged oil pumps 105 are fixed to the front of the back plate 103, and their outlets are connected to the independent lubrication interface 106 via connecting rings 201. A fluororubber sealing ring 202 is provided between the connecting ring 201 and the miniature pressure pump 203 to prevent high-pressure oil leakage.
[0037] The miniature pressure pump 203 has multiple independent lubrication units 204 radially distributed at its output end. These independent lubrication units 204 are arranged in a ring array, and each unit is equipped with a 0.1mm orifice nozzle to achieve 360° coverage for oil injection. An oil trough 303 is formed along the edge of the fixed slot 302 to recover spilled oil during lubrication.
[0038] The specific working steps of this automatic lubrication component are as follows:
[0039] 1. Positioning and Start-up: The drive motor 3 receives the PLC command and drives the lead screw 4 to rotate. Through the meshing of the micro gearbox, the slider 6 moves along the track 5 to the target lubrication station.
[0040] 2. Locking and oiling: The telescopic rod 102 pushes the limiting guard plate 104 into the positioning hole of the mixer, the oil pump 105 starts to supply oil, and the micro pressure pump 203 sprays the lubricating oil precisely through the independent lubrication unit 204 at the preset pressure;
[0041] 3. Oil spillage recovery: Excess lubricating oil flows into the oil tank 303 along the fixed back plate 103, avoiding contamination of materials;
[0042] 4. Reset cycle: After oil injection is completed, the telescopic rod 102 retracts and the system moves to the next station.
[0043] For any parts not mentioned in this application, existing technologies may be used or referenced.
[0044] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
[0045] The above description is merely an embodiment of this application and is not intended to limit the scope of this application.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
