A multi-angle intelligent mixer for real stone paint

Abstract

This invention relates to a multi-angle intelligent mixer for stone paint. The technical solution involves a mixing head that rotates on its own axis and revolves around the material barrel's axis while simultaneously achieving non-linear vertical movement. This means the mixing head's position is not simply a linear displacement, but rather an adaptive tilt adjustment based on hydraulic input. Compared to traditional linear lifting, this method provides the mixing head with more comprehensive and variable angles and positions, allowing its tilt angle and position to continuously change as it moves up and down within the paint barrel. This ensures the mixing head never contacts the barrel wall, achieving comprehensive, multi-angle, and multi-level mixing of the paint, significantly improving mixing efficiency. The device is designed to simulate the process of manually mixing stone paint using a small hand-held mixer within the barrel, replacing manual hand-held rotation and reducing worker fatigue.

Description

Technical Field

[0001] This invention relates to the field of colored sand mixing equipment, and in particular to a deep, multi-angle intelligent mixer for real stone paint. Background Technology

[0002] Stone paint is made by mixing natural or artificial stone powder of various colors. Finished stone paint is usually packaged in a container. The original stone paint has relatively few color options. In actual use, secondary color matching is often required according to customer needs. This color matching process can be done by adding natural stone powder, dye stone powder, or directly adding raw lacquer dye. Different methods result in different stone paint effects, and the cost and quality also vary.

[0003] In the secondary mixing process, materials are often directly added to the barrel of real stone paint, and the mixing head of a small mixer is inserted into the barrel for mixing. In order to ensure the uniformity and efficiency of the mixing, workers often need to constantly adjust the position of the mixer head in the barrel. During this process, workers not only need to hold the mixer, but also need to move and constantly adjust the mixing angle and depth. The labor intensity is high and labor is arduous. There is a patent with application number 201921199210.2 and patent name: A new type of anti-corrosion coating mixer. It discloses that by installing the mixing rod at an angle, the mixing rod can revolve around the main drive shaft at an angle under the drive of the main drive shaft, and the main drive shaft can simultaneously drive the mixing rod to rotate by itself through gear transmission. Thus, a single motor drives the mixing head on the mixing rod to rotate by itself and revolve, resulting in better mixing effect and improved mixing efficiency.

[0004] However, although such equipment has the cooperation of self-adhesion and revolution of the stirring rod, and can provide lifting and stirring functions inside the cylinder through the lifting device, the stirring head has a single stirring position inside the cylinder. Although there is revolution and lifting inside the cylinder, the actual stirring track formed is a cylindrical structure, which still has stirring blind spots and cannot truly achieve all-round and multi-angle stirring. Therefore, in the process of stirring paint, there are still problems of incomplete stirring range and unsatisfactory effect. Therefore, there is a need for a small stirring device that can effectively help workers to operate with less effort, improve workers' work efficiency, reduce workers' labor intensity, and improve stirring efficiency. Summary of the Invention

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 6 As can be seen, the present invention includes a bracket 1, on which a vertical reciprocating screw 2 is mounted. A nut 3 is fitted onto the reciprocating screw 2, and rotation of the reciprocating screw 2 causes the nut 3 to move up and down reciprocally. A hydraulic cylinder 4 is mounted at an angle at the lower end of the reciprocating screw 2. The extended end of the hydraulic cylinder 4 faces downward and is fixed with a stirring head 5. A first sleeve 6 is fitted onto the cylinder body of the hydraulic cylinder 4, and the hydraulic cylinder 4 rotates within the first sleeve 6 but cannot move. A diagonal rod 7 with its lower end inclined outward is fixed to the lower end of the reciprocating screw 2, and the free end of the diagonal rod 7 is hinged to the first sleeve 6. A second sleeve 8 is fitted onto the tail of the hydraulic cylinder 4, and the hydraulic cylinder 4 rotates within the sleeve but cannot slide. A first annular groove 9 is provided on the lower end face of the nut 3. A slider 10 is provided in the first annular groove 9. A connecting rod is hinged to the first slider 10. The free end of the connecting rod is hinged to the second sleeve 8. A first cylinder 11 is coaxially provided above the nut 3. A second cylinder 12 is fitted on the outer side of the first cylinder 11 at intervals. The first cylinder 11 and the second cylinder 12 form an annular cavity with the opening facing downward. The annular cavity is rotatably mounted on the bracket 1. An annular piston 13 is slidably mounted against the wall inside the annular cavity. A pull rod 14 is mounted on the annular piston 13. A second annular groove 15 is provided on the upper end face of the nut 3. The lower end of the pull rod 14 is placed in the second annular groove 15. The annular cavity is connected to the hydraulic cylinder 4 through a hydraulic hose 16. The hydraulic hose 16 is rotatably mounted on the bottom of the hydraulic cylinder 4.

[0020] To facilitate the installation of various components, the bracket 1 includes a mounting plate, through which a reciprocating screw 2 passes. A first motor that drives the reciprocating screw 2 to rotate is installed at the upper end of the mounting plate. The bracket 1 has three legs on the left, right, and rear sides. The three legs are fixed into a whole by connecting rods. Each of the left and right legs has a telescopic rod 17 with its extended end facing each other. A spring 18 that can be reset and extended is fitted on the telescopic rod 17. Each end of the telescopic rod 17 is fixed with an arc-shaped plate 19. The openings of the two arc-shaped plates 19 face each other. The position of each telescopic rod 17 is fixedly connected to the mounting plate by an L-shaped rod. The L-shaped rod does not interfere with the hydraulic cylinder 4.

[0021] In order to enable the reciprocating screw 2 to rotate and the nut 3 to move up and down, a vertical guide rod 20 is fixed on the bracket 1. The guide rod 20 passes through the nut 3, and the nut 3 can move up and down along the screw. The guide rod 20 and the reciprocating screw 2 are both placed inside the first cylinder 11.

[0022] In order to achieve the self-rotation drive of the hydraulic cylinder 4, a first gear 21 driven by a second motor is fixed on the outer side of the first sleeve 6, and a second gear 22 that meshes with the first gear 21 is mounted on the cylinder body of the hydraulic cylinder 4.

[0023] In order to achieve the rotatable installation of the hydraulic hose 16 and the tail of the hydraulic cylinder 4, a connector 23 is rotatably installed at the tail of the hydraulic cylinder 4. The connector 23 is fixed on the second sleeve 8, and the hydraulic hose 16 is rotatably connected to the hydraulic cylinder 4 through the connector 23.

[0024] The specific working process of this invention is as follows: When using this device, a bucket containing real stone paint is placed below the support 1. The telescopic rods 17 on both sides of the support 1 are compressed, causing the spring 18 to be compressed. The bucket is then placed between two arc-shaped plates 19. Under the reset action of the spring 18, the bucket is clamped by the arc-shaped plates 19. At this time, the bucket is coaxially fixed with the reciprocating screw 2. The stirring head 5 is placed inside the bucket. The first motor drives the reciprocating screw 2 to rotate, and the second motor drives the hydraulic cylinder 4 to rotate. The output shaft of the second motor, through the meshing of the first gear 21 and the second gear 22, drives the hydraulic cylinder 4 to rotate within the first sleeve 6 and the second sleeve 8. The first sleeve 6 and the second sleeve 8 are respectively hinged by the inclined rod 7 and the connecting rod to achieve the limiting position. The rotation of the hydraulic cylinder 4 causes the stirring head 5 to rotate inside the material bucket. The rotation of the first motor drives the inclined rod 7 through the reciprocating screw 2 to drive the hydraulic cylinder 4 to rotate around the main line of the reciprocating screw 2. During this process, the nut 3 does not rotate but only moves up and down. Thus, when the nut 3 moves upward under the action of the connecting rod, the upper end of the hydraulic cylinder 4 driven by the connecting rod moves closer to the reciprocating screw 2. At the same time, the annular cavity is squeezed by the pull rod 14 and the annular piston 13. During this process, the hydraulic oil in the annular cavity enters the hydraulic cylinder 4, causing the hydraulic cylinder 4 to extend. At the same time, the outward tilt angle of the hydraulic cylinder 4 decreases, presenting a shape as shown in the figure. Figure 1In the state described, when nut 3 moves downward, the outward tilt angle of hydraulic cylinder 4 driven by nut 3 via connecting rod increases. Simultaneously, nut 3 drives annular piston 13 downward via pull rod 14. At this time, hydraulic oil in hydraulic cylinder 4 is drawn into the annular cavity, reducing the hydraulic pressure in hydraulic cylinder 4, causing hydraulic cylinder 4 to retract. To assist the retraction of hydraulic cylinder 4, a tension spring can be installed inside hydraulic cylinder 4. At this time, the device exhibits the following characteristics: Figure 2 The state shown can be repeated to simulate the process of a worker manually mixing materials.

[0025] When the device is running, the rotation of the reciprocating screw 2 drives the hydraulic cylinder 4 to revolve around the reciprocating screw 2. At this time, the hydraulic cylinder 4 drives the connecting rod to slide in the first slide groove via the slider 10. The rotation of the hydraulic cylinder 4 around the reciprocating screw 2 also drives the annular cavity to rotate via the hydraulic hose 16. At the same time, the pull rod 14 slides in the second slide groove to meet its rotation requirements. The stroke of the nut 3 moving up and down and the amount of hydraulic oil in the annular cavity should keep the extension length of the hydraulic cylinder 4 matched so that the stirring head 5 approaches but does not contact the inner wall of the material bucket during the extension and retraction process. The tilt angle of the connecting rod driving the hydraulic cylinder 4 should also meet the motion estimation requirements.

[0026] This device has the following advantages compared to traditional equipment:

[0027] 1. This device is designed to simulate the process of manually mixing stone paint in a bucket using a small hand-held mixer. It enables the mixing head 5 to continuously mix the paint at multiple positions and heights in the bucket, replacing manual hand-held rotation, effectively improving mixing efficiency and reducing the labor intensity of workers.

[0028] 2. The rotation of the reciprocating screw 2 enables the nut 3 to move up and down reciprocally. The up and down movement of the nut 3 causes the tilt angle and length of the hydraulic cylinder 4 to change adaptively. When the nut 3 moves upward, the hydraulic cylinder 4 extends and tilts outward at a small angle. At this time, the stirring head 5 moves towards the bottom of the bucket to stir. When the nut 3 moves downward, the hydraulic cylinder 4 retracts and tilts outward at a large angle. At this time, the stirring head 5 moves towards the top of the bucket to stir. In conjunction with the rotation of the hydraulic cylinder 4 itself, the stirring head 5 fully exerts its stirring effect at various positions in the bucket.

[0029] 3. This device achieves non-linear up-and-down movement by rotating the stirring head 5 and revolving around the axis of the material barrel. That is, the position of the stirring head 5 is not simply a linear displacement, but an adaptive tilt adjustment based on the hydraulic input. Compared with the traditional linear lifting, this method can provide the stirring head 5 with a more comprehensive and variable angle and position. As it moves up and down in the paint barrel, the tilt angle and position of the stirring head constantly change. Under the premise that the stirring head 5 never comes into contact with the wall of the material barrel, it can achieve an all-round, multi-angle, and multi-level stirring effect of the paint, which greatly improves the stirring efficiency.
