Description

Technical Field

[0001] The invention relates to coating processing, and more particularly to an environmentally friendly coating and a production process thereof. Background Art

[0002] Traditional stirring equipment usually uses fixed-position stirring blades, or improves its motion trajectory, such as up and down or rotation, which makes it difficult to effectively break the ability of solid raw materials such as rosin, wax or filler. These raw materials are prone to form lumps during the stirring process, resulting in uneven dispersion, affecting the final performance of the coating such as hiding power and leveling. Some equipment of existing solutions improves the dispersion effect by increasing the stirring speed or extending the stirring time, but this method is not only energy-intensive, but may also damage the raw material structure due to excessive stirring. During the stirring process, some raw materials such as resins and waxes tend to adhere to the inner wall of the container, forming a "hanging wall" phenomenon. These hanging wall raw materials cannot participate in the mixing, resulting in an imbalance in the formula ratio, while increasing the difficulty of cleaning and the waste of raw materials. There is also an improved solution of scraping the raw materials on the inner wall, but the long-term contact will wear the container and make a lot of noise. The design of traditional stirring equipment is usually targeted at specific formulas or processes, and it is difficult to adapt to the diverse raw material characteristics in the production of environmentally friendly coatings, such as changes in the ratio of solid and liquid raw materials and viscosity differences. For example, high-viscosity coatings require stronger shear forces, while low-viscosity coatings need to avoid the generation of bubbles. Summary of the invention

[0003] The invention provides an environmentally friendly coating and a production process thereof, aiming at being able to change the stirring strategy as required.

[0004] The above purpose is achieved through the following technical solutions:

[0006] The driving mechanism comprises a first motor fixedly connected to the base, the output shaft of the first motor is vertically arranged, and the output shaft of the first motor and the driving seat are driven by a first pulley belt assembly.

[0007] The lifting mechanism comprises a base frame, on which two lead screws are rotatably connected, and the two lead screws are synchronously driven through a second pulley belt assembly, a second motor is fixedly connected to the bottom of one of the lead screws, and the base is spirally driven on the two lead screws.

[0008] The stirring assembly comprises an arm body, the upper part of the arm body is fixedly connected with a shaft, and the shaft is rotatably connected to the driving seat.

[0009] A guide rail is fixed on the arm body.

[0010] Two stirring assemblies are arranged in mirror symmetry, and the two guide rails are arranged face to face. When the arm body is vertical, the distance between the two guide rails gradually decreases from the upper part to the middle part, and the distance from the middle part to the lower part gradually increases; a telescopic cylinder is fixedly connected to the driving seat, and the telescopic cylinder passes through the base longitudinally. A straight arm is fixedly connected to the bottom of the telescopic cylinder, and two push rods are installed on the straight arm, and the two push rods are respectively in contact with the two guide rails.

[0013] One end of a rotating spring is fixedly connected to each arm body, and the other end of the rotating spring is fixedly connected to the driving seat.

[0014] A process for producing an environmentally friendly coating, using the above-mentioned environmentally friendly coating production equipment, comprises the following steps:

[0015] Step 1: a block of hot-melt solid raw materials, such as a large waxy substance, is dispersed by a stirring assembly to obtain a dispersed material;

[0016] Step 2: the dispersed material is mixed with other raw materials and stirred by a stirring component;

[0017] Among them, the environmentally friendly coating includes the following ingredients in mass percentage: 40% to 50% water-based resin, 5% to 10% rosin, 15% to 20% titanium dioxide, 10% to 15% talc, 1% to 3% polyethylene wax, paraffin or modified wax, 1% to 2% dispersant and 1% to 2% calcium zinc composite stabilizer, and the rest is deionized water.

[0018] The beneficial effects of the environmentally friendly coating and its production process of the present invention are:

[0019] The position of the second stirring member is changed as needed to scrape the raw materials on the inner wall of the container instead of maintaining contact continuously. The ultrasonic transducer is turned on as needed, and can be adjusted to be in the center of the container or away from the center to remove bubbles. An electrical device, such as a battery or a conductive structure, can be set on the top of the drive seat to power the telescopic cylinder and the ultrasonic transducer. The top power supply solution is safer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] An environmentally friendly coating production equipment, such as Figures 1 to 3 And 5, including a lifting mechanism, the lifting mechanism includes a base frame 5, the base frame 5 is rotatably connected to two lead screws 6, the two lead screws 6 have the same thread rotation direction, the lower sides of the two lead screws 6 are synchronously driven by a second pulley belt assembly 7, the bottom of the lead screw 6 on the right is fixedly connected to the output shaft of the second motor 8, the output shaft of the second motor 8 is arranged upward and coaxially with the lead screw 6, the second motor 8 is used to drive the lead screw 6 on the right to rotate around the axis of the output shaft of the second motor 8, so that the two lead screws 6 rotate synchronously, and the base 1 is spirally transmitted to the two lead screws 6, and the height of the base 1 can be adjusted.

[0028] A driving seat 2 is rotatably connected to the base 1, and a stirring assembly is installed on the base 1. The stirring assembly includes a first motor 3 fixed to the base 1, and the output shaft of the first motor 3 is vertically arranged. The output shaft of the first motor 3 and the driving seat 2 are synchronously driven through a first pulley belt assembly 4, so that the first motor 3 is used to drive the driving seat 2 to rotate.

[0029] Further explanation, combined with Figure 4The stirring assembly includes an arm body 9, a shaft 10 is fixedly connected to the upper part of the arm body 9, and the shaft 10 is rotatably connected to the driving seat 2. A guide rail 11 is fixedly connected to the right end of the arm body 9. The right end face of the guide rail 11 gradually extends to the right from top to bottom, passes through the middle of the longitudinal height, and then extends to the left to form a triangular structure with the arm body 9; the stirring assembly is provided with two mirror-symmetrical guide rails 11, and the two guide rails 11 are arranged face to face. When the arm body 9 located on the left rotates clockwise and the arm body 9 located on the right rotates counterclockwise, and the rotation range is both acute angles, the distance between the two arm bodies 9 gradually increases, and vice versa, the distance between the two arm bodies 9 gradually decreases; the rotation range of the two arm bodies 9 is adjusted by the following scheme: a telescopic cylinder 12 is fixedly connected to the driving seat 2, the telescopic end of the telescopic cylinder 12 is arranged downward, the telescopic cylinder 12 passes through the base 1 longitudinally, and a straight arm 13 is fixedly connected to the bottom of the telescopic cylinder 12, and the left and right ends of the straight arm 13 are each rotatably connected to a push rod 14, and the two push rods 14 are respectively in contact with the inner end faces of the two guide rails 11.

[0030] Preferably, one end of a rotating spring 20 is fixed to each arm 9, and the other end of the rotating spring 20 is fixed to the drive seat 2 to increase the force to keep the two arm bodies 9 vertical. The axis of the telescopic cylinder 12 coincides with the rotation axis of the drive seat 2. A first stirring member 15 is fixed to each of the back-to-back surfaces of the two guide rails 11. The first stirring member 15 is a bent pipe member in a C shape to expand the radial range of the arm body 9. At the same time, an ultrasonic transducer 16 is fixed to each of the face-to-face surfaces of the two guide rails 11 to increase the emulsification ability. On the other hand, a second stirring member 17 is fixed to each of the back-to-back surfaces of the two guide rails 11. When the two arm bodies 9 are vertical, the two second stirring members 17 are located in a virtual V shape. The second stirring member 17 protrudes radially from the first stirring member 15, so that after the distance between the two arm bodies 9 is increased and unfolded, the second stirring member 17 can contact the inner wall of the container in a vertical state, while the first stirring member 15 does not contact the inner wall of the container and is located on the inner side of the container. A material-pickup portion 18 is fixedly connected to the bottom of the second stirring member 17, and the free ends of the two material-pickup portions 18 are arranged facing each other. When the two arms 9 are vertical, the two material-pickup portions 18 are horizontal. A third stirring member 19 is fixedly connected to each of the facing surfaces of the two arms 9. The third stirring member 19 is located on the arm 9 at the other side of the guide rail 11, that is, the ultrasonic transducer 16 is located between the third stirring member 19 and the guide rail 11. At the same time, the third stirring member 19 protrudes radially inward from the guide rail 11 and the ultrasonic transducer 16. The third stirring member 19 is C-shaped to extend between the two arms 9, that is, inward.

[0031] When the two push rods 14 are located at the upper part of the two guide rails 11, the two arms 9 are vertical. At this time, when the two arms 9 rotate due to the rotation of the driving seat 2, they are used to stir the center of the container or destroy the wax-like substance to break up and disperse the wax-like substance. The two material-pickup parts 18 are also easier to insert into the center of the solid raw material, and the solid raw material is destroyed from the center of the solid raw material as it rotates. When the two push rods 14 gradually move to the middle of the two guide rails 11, the distance between the two arms 9 increases, and the distance between the two arms 9 gradually decreases as the push rods 14 further descend. Therefore, the telescopic cylinder 12 expands and contracts once, and the two arms 9 expand and contract twice. A third stirring member 19 is added between the two arms 9 to scrape off the outer edge of the solid raw material.
