[0029] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0030] The existing stage light shaft structure is usually a split type. During the installation process, a separate aluminum alloy shaft needs to be assembled onto the sheet metal base bracket of the stage light and then fixed with screws. This structure has some drawbacks in practical applications: (1) The assembly process is cumbersome, which increases the assembly cost; (2) The split shaft and sheet metal base bracket make the parts processing more difficult, resulting in high processing costs and long cycles; (3) The large number of parts and the variety of materials increase the procurement and management costs. Example

[0031] As shown in Figures 1-4, this embodiment provides a stone paint preparation device with automatic cleaning function, comprising:

[0032] A frame is provided, on which a mixing tank 1 is provided, and a feed inlet 11 is provided at the top of the mixing tank 1; a mixing structure 8 is provided inside the mixing tank, the mixing structure 8 includes a mixing main shaft 81, and multiple main mixing blades 82 are provided on the mixing main shaft 81; a water cavity 813 is provided in the mixing main shaft 81, and the water cavity 813 is arranged along the axial direction of the mixing main shaft 81;

[0033] The stirring spindle 81 is provided with a plurality of high-pressure nozzles 815, the high-pressure nozzles 815 are connected to the water chamber 813, and the high-pressure nozzles 815 are provided with a detachable protective cover 814.

[0034] The frame is also equipped with a drive device 6, which drives the stirring spindle 81 to rotate.

[0035] Specifically, the stirring structure 8 is installed inside the mixing tank 1. The stirring main shaft 81 is installed parallel to the horizontal plane at the center of the mixing tank 1, and its two ends are rotatably connected to the mixing tank 1 through bearings to ensure that the stirring main shaft 81 can rotate stably and smoothly. The stirring main shaft 81 is equipped with multiple main stirring blades 82, which can fully stir the stone paint raw materials when the stirring main shaft 81 rotates, thereby improving stirring efficiency and uniformity.

[0036] The mixing shaft 81 has a hollow structure, forming a water cavity 813 that extends through the entire mixing shaft 81 along its axial direction. Six high-pressure nozzles 815 are evenly arranged on the side wall of the mixing shaft 81. Each high-pressure nozzle 815 is connected to the water cavity 813 via a pipe, and the nozzles are detachably threaded to the pipes for easy disassembly and maintenance. Each high-pressure nozzle 815 is equipped with a detachable protective cover 814. In one embodiment, the protective cover 814 is connected to the high-pressure nozzle 815 via a snap-fit ​​mechanism. When the equipment is preparing stone paint, the protective cover 814 prevents stone paint raw materials from entering the high-pressure nozzle 815, thus avoiding blockage. The drive unit 6 is installed on one side of the frame and includes a motor, a reducer, and a transmission belt 7. The output shaft of the motor is connected to the input shaft of the reducer via the transmission belt 7, and the output shaft of the reducer is connected to the top of the mixing shaft 81. The motor is a variable frequency motor, which can adjust the speed of the stirring shaft 81 according to different stages of the preparation of the stone paint.

[0037] After the stone paint is prepared, when cleaning the equipment, first open the protective cover 814, then connect the external water source to the water chamber 813 and inject high-pressure water into the water chamber 813. Start the motor to drive the stirring shaft 81 to rotate, and the high-pressure water is sprayed out through the high-pressure nozzles 815 to thoroughly rinse the inner wall of the mixing tank 1, the main stirring blades 82, and other components inside the mixing tank 1. Since the high-pressure nozzles 815 are evenly distributed on the stirring shaft 81, and the stirring shaft 81 is rotating, it can be ensured that every corner inside the mixing tank 1 can be cleaned, realizing the function of automatic cleaning.

[0038] The aforementioned stone paint preparation equipment with automatic cleaning function, by setting a water chamber 813 and high-pressure nozzles 815 on the mixing spindle 81, can quickly start the automatic cleaning program after the equipment completes the stone paint preparation. Compared with the traditional manual cleaning method, there is no need for operators to enter the mixing tank 1 for manual scrubbing, which greatly saves cleaning time. Moreover, the high-pressure nozzles 815 are evenly distributed and rotate with the mixing spindle 81, which can perform all-round and thorough cleaning of the inside of the mixing tank 1, ensuring that the stone paint residue in the mixing tank 1 is completely removed. This avoids the problem of cross-contamination of stone paint raw materials caused by incomplete manual cleaning, and ensures the quality stability of each batch of stone paint products. Furthermore, the surface of the mixing spindle 81 is provided with a mounting groove, and multiple high-pressure nozzles 815 are installed in the mounting groove.

[0039] Furthermore, in one embodiment, the protective cover 814 is disposed at the opening of the mounting groove, and the protective cover 814 is slidably disposed on the stirring spindle 81.

[0040] Specifically, one side of the mounting groove is provided with a receiving cavity for a protective cover 814. The protective cover 814 is slidably installed in the receiving cavity. When the high-pressure nozzle 815 is needed, the protective cover 814 is retracted to expose the high-pressure nozzle 815, allowing the high-pressure nozzle 815 to spray high-pressure water without obstruction, thus cleaning the mixing tank 1 in all directions. There will be no dead corners in the cleaning due to the obstruction of the protective cover 814, ensuring a more thorough cleaning, improving the cleanliness of the equipment, reducing the residue of the stone paint, and ensuring the quality of the stone paint products produced subsequently.

[0041] When the high-pressure nozzle 815 is not in use, pull out the protective cover 814 to cover the high-pressure nozzle 815 to prevent the stone paint from clogging the nozzle.

[0042] Furthermore, the stirring structure 8 also includes an auxiliary shaft 83, which is fixed on the multiple main stirring blades 82, and the axis of the auxiliary shaft 83 is parallel to the axis of the stirring main shaft 81;

[0043] The auxiliary shaft 83 is provided with multiple auxiliary stirring blades 831.

[0044] Furthermore, two auxiliary shafts 83 are provided, the two auxiliary shafts 83 are parallel to each other, and each of the two auxiliary shafts 83 is provided with multiple auxiliary stirring blades 831.

[0045] Specifically, during the mixing process, the auxiliary stirring blade 831 forms a different mixing path and area from the main stirring blade 82. The main stirring blade 82 mainly stirs and mixes the raw materials of the stone paint over a large area, while the auxiliary stirring blade 831 can penetrate into local areas of the raw materials to supplement the mixing of parts that the main stirring blade 82 has not fully stirred. This achieves three-dimensional mixing of the raw materials of the stone paint, effectively avoiding the formation of dead zones in the mixing of the raw materials, making the components of the stone paint more uniformly mixed, and significantly improving the formulation quality of the stone paint.

[0046] Furthermore, both ends of the stirring shaft 81 penetrate the stirring tank 1 and are exposed outside the stirring tank 1, and a first pulley 811 and a second pulley 812 are respectively provided at both ends of the stirring shaft 81; the driving device 6 includes a drive motor 61 and a transmission wheel 62, the output end of the drive motor 61 is fixedly connected to the transmission wheel 62, and a transmission belt 7 is provided between the transmission wheel 62 and the first pulley 811.

[0047] The mixing shaft 81 has a first pulley 811 and a second pulley 812 at both ends. The drive motor 61 is connected to the first pulley 811 via a transmission wheel 62 and a transmission belt 7, forming a belt drive structure. This transmission method can effectively buffer the impact force during the start-up and operation of the drive motor 61, avoiding damage to the mixing shaft 81 due to excessive instantaneous torque. At the same time, the belt has a certain degree of elasticity, which can compensate for the installation error between the mixing shaft 81 and the drive motor 61 to a certain extent, ensuring stable and continuous power transmission to the mixing shaft 81, making the mixing process more stable, and ensuring that the stone paint raw materials can be uniformly and efficiently mixed in the mixing box 1, thereby improving product quality.

[0048] The two ends of the mixing shaft 81 are exposed outside the mixing tank 1 and are equipped with pulleys. When the equipment malfunctions and needs maintenance, the operator can more easily inspect, replace and adjust the pulleys, transmission belt 7 and drive motor 61 and other components.

[0049] In a preferred embodiment, the bottom of the mixing tank 1 is provided with a discharge port, and a collection box 2 is provided at the discharge port, the collection box 2 being connected to the mixing tank 1;

[0050] A spiral feeding pipe 3 is provided below the mixing tank 1, and the top of the spiral feeding pipe 3 is connected to the collection box 2; a propeller 31 is provided in the spiral feeding pipe 3, one end of the propeller 31 is exposed outside the spiral feeding pipe 3, and a third pulley 311 is provided on the propeller 31 exposed outside the spiral feeding pipe 3, and a transmission belt 7 is provided between the first pulley 811 and the third pulley 311.

[0051] The bottom of the mixing tank 1 has a discharge port that connects to the collection box 2, allowing the prepared stone paint to flow smoothly into the collection box 2 for temporary storage. The spiral feeding pipe 3 is connected to the collection box 2, and together with the internal propeller 31, it can continuously and stably transport the stone paint in the collection box 2, avoiding problems such as blockage and material interruption that may occur with traditional discharge methods.

[0052] The first pulley 811 and the third pulley 311 are connected by a transmission belt 7, so that the stirring shaft 81 can drive the propeller 31 to rotate synchronously when it rotates. This cleverly utilizes the power of the stirring shaft 81 to drive the spiral feeding pipe 3, eliminating the need for an additional independent drive motor 61 and reducing the equipment's energy consumption. At the same time, this power reuse design simplifies the equipment's power system structure, reduces manufacturing and operating costs, and improves energy efficiency.

[0053] Furthermore, a discharge box 5 is also provided on the frame, and the end of the spiral feeding pipe 3 away from the mixing tank 1 is connected to the discharge box 5;

[0054] The discharge box 5 is provided with a discharge stirring paddle 51. One end of the stirring paddle 51 is exposed outside the discharge box 5, and a fourth pulley 52 is provided on the stirring paddle 51 exposed outside the discharge box 5. A transmission belt 7 is provided between the fourth pulley 52 and the second pulley 812.

[0055] The discharge mixing paddle 51 installed inside the discharge box 5 can perform secondary mixing on the stone paint conveyed by the spiral feeding pipe 3. During the conveying process of the stone paint, factors such as pipe friction and gravity may cause some materials to separate or become unevenly mixed. The mixing of the discharge mixing paddle 51 can make the stone paint mix evenly again, ensuring that the proportions of each component in the stone paint output from the discharge box 5 are consistent, effectively improving product quality. The second pulley 812 is connected to the fourth pulley 52 by the transmission belt 7, and the rotational power of the mixing shaft 81 drives the discharge mixing paddle 51 to work, eliminating the need for a separate drive motor 61 for the discharge mixing paddle 51. This design further optimizes the power system of the equipment and reduces the overall energy consumption and manufacturing cost of the equipment.

[0056] More preferably, this structure integrates the mixing shaft 81 in the mixing tank 1, the propeller 31 in the spiral feeding pipe 3, and the discharge mixing paddle 51 in the discharge box 5 into a cohesive whole. The components work collaboratively via belt drives, achieving automated connection throughout the entire process from the preparation and conveying of the stone paint to its discharge, eliminating the need for frequent manual intervention and adjustments, thus improving the automation level and production efficiency of the equipment.

[0057] Furthermore, the bottom of the frame is provided with casters 9, and the casters 9 are provided with locking devices.

[0058] The casters 9 at the bottom of the frame allow the stone paint mixing equipment to move freely within the workshop, whether for initial installation or adjustment. The locking devices on the casters 9 quickly and securely fix the equipment in place once it reaches the designated position, preventing displacement due to mixing vibrations, uneven ground, or external impacts during operation. This effectively ensures the stability and safety of the equipment's operation.
