Description

Technical Field

[0001] This utility model belongs to the field of environmentally friendly coating production technology, specifically an environmentally friendly water-based coating mixing equipment. Background Technology

[0002] Environmentally friendly water-based coatings are green coating products that use water as the main dispersion medium and are characterized by low VOCs, benzene-free, and formaldehyde-free. They are widely used in construction and home decoration, wood coating, and industrial anti-corrosion. Their production process requires the fine dispersion and mixing of raw materials such as resins, pigments, fillers, and environmentally friendly additives using efficient blending equipment to ensure film performance and environmental standards. As a core piece of equipment in coating production, the high-speed disperser, with its efficient shearing and mixing capabilities, has become the mainstream equipment in the blending process of environmentally friendly water-based coatings. It mainly uses a high-speed rotating dispersing disc to impact, crush, and homogenize materials.

[0003] However, traditional high-speed dispersers still have significant shortcomings when applied to the production of environmentally friendly water-based coatings, making it difficult to meet the current demands for efficient, safe, and automated production. Specifically: First, the mixing area is mostly an open structure, lacking a sealing cover that adapts to the material container opening. During high-speed mixing, this easily leads to material splashing, dust generation, and the release of volatile organic compounds, causing not only raw material waste and environmental pollution but also threatening the safety of the operating environment. Second, the material container fixing method is relatively primitive; the clamping mechanism is not linked to the equipment's lifting action, resulting in low automation, cumbersome operation, and poor clamping reliability. This easily leads to problems such as material container displacement and shaking during mixing, seriously affecting the uniformity of dispersion and the safety of equipment operation.

[0004] Therefore, an environmentally friendly water-based coating mixing equipment is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides an environmentally friendly water-based coating mixing device, which has the advantages of being environmentally friendly and safe, self-adaptive sealing, linkage clamping, and highly automated.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly water-based coating mixing device, comprising a base, a hydraulic cylinder installed at the rear of the top of the base, a top seat connected to the piston rod of the hydraulic cylinder, a rotary drive mechanism installed at the front of the top seat, a central shaft connected to the rotary drive mechanism, a dispersing disc connected to the bottom end of the central shaft, a cover plate provided on the outer side of the central shaft, a plurality of circumferentially evenly distributed spring telescopic rods connected to the top of the cover plate, a top seat connected to the top end of the spring telescopic rods, a placement groove provided below the dispersing disc, the placement groove being located on the base, a clamping assembly provided on the outer side of the placement groove, a linkage assembly connected to the clamping assembly, and the linkage assembly connected to the top seat;

[0007] The clamping assembly includes a bidirectional lead screw disposed in the base, the bidirectional lead screw being threadedly connected to two symmetrical threaded sliders with opposite directions of movement, the threaded sliders being connected to a U-shaped rod, and the end of the U-shaped rod being fixedly connected to a clamping plate;

[0008] The linkage assembly includes a first sprocket fixed in the middle of a bidirectional lead screw, a second sprocket connected to the first sprocket via a first chain, a third sprocket fixedly connected to the second sprocket via a coaxial connecting rod, a fourth sprocket connected to the third sprocket via a second chain, a gear fixedly connected to the fourth sprocket via a coaxial connecting rod, a rack meshing with the gear, and a top seat fixedly connected to the top of the rack.

[0009] Preferably, a fixing ring is provided on the outer side of the cylinder barrel near the top of the cylinder. A lug is fixedly connected to the front side of the fixing ring. A guide hole is provided on the lug, and a guide rod is provided in the guide hole. The top end of the guide rod is fixedly connected to a top seat.

[0010] Preferably, the spring telescopic rod includes a fixed shell with a top seat fixedly connected to the top, a movable plate is provided inside the fixed shell, a spring is connected to the top of the movable plate, a movable rod is fixedly connected to the bottom of the movable plate, and the bottom end of the movable rod passes through the fixed shell and is fixedly connected to a cover plate.

[0011] Preferably, the clamping plates are symmetrically arranged above the base, and the inner wall of the clamping plates is provided with anti-slip pads.

[0012] Preferably, the side of the fourth sprocket away from the gear is rotatably connected to a vertical plate via a bearing, and the bottom end of the vertical plate is fixedly connected to a base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a follow-up cover plate and spring telescopic rod structure, allows the cover plate to be pressed down and fitted to the opening of the mixing container when the central shaft moves down for dispersion operations. The elastic pressure provided by the spring telescopic rod ensures a tight seal between the cover plate and the container opening, which effectively avoids the problems of material splashing, dust and volatile organic compound emission during high-speed mixing. It can also adapt to mixing containers of different heights, reduce the volatilization of moisture and additives, improve the safety and raw material utilization rate of environmentally friendly water-based coating production, reduce mixing noise and prevent foreign objects from falling into the material.

[0015] 2. This utility model utilizes the linkage design of the clamping component and the linkage component. By using the power of the top seat descending, through the meshing transmission of rack and pinion and gear, and the synchronous transmission of multiple sets of sprockets and chains, the bidirectional lead screw drives the clamping plates on both sides to automatically approach and clamp the mixing container. This achieves integrated linkage between equipment lifting and material barrel clamping, eliminating the need for additional power sources and manual operation. It simplifies the production process, improves the degree of automation, and ensures the stable fixation of the material barrel during the mixing process, preventing displacement or shaking. This significantly improves the dispersion uniformity and production safety of environmentally friendly water-based coatings. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 5 As shown, this utility model provides an environmentally friendly water-based coating mixing device, including a base 1, which provides a stable installation support foundation for the entire device. A hydraulic cylinder 2 is installed on the rear side of the top of the base 1, providing linear drive power for lifting and lowering the device. The piston rod of the hydraulic cylinder 2 is connected to a top seat 3. The hydraulic cylinder 2 drives the top seat 3 to complete the up-and-down lifting action through the extension and retraction of the piston rod. A rotary drive mechanism 4 is installed on the front side of the top seat 3, providing core rotary drive force for material dispersion. The rotary drive mechanism 4 is connected to a central shaft 5, which transmits rotational torque to a dispersion disc 6. The bottom end of the central shaft 5 is connected to the dispersion disc 6, which rotates at high speed to achieve shearing, dispersion, and mixing of coating raw materials. A cover plate 7 is provided on the outside of the central shaft 5. The cover plate 7 is used to cover the mouth of the mixing container to prevent material splashing and volatile matter from escaping. The top of the cover plate 7 is connected to several spring telescopic rods 8 that are evenly distributed in a circumferential direction. The spring telescopic rods 8 provide continuous elastic downward pressure for the cover plate 7. The top of the spring telescopic rods 8 is connected to the top seat 3, so that the cover plate 7 rises and falls synchronously with the top seat 3 and adapts to fit the mouth of the container. The lower part of the dispersion plate 6 is provided with a placement groove 9. The placement groove 9 is used to initially position the mixing container to avoid displacement. The placement groove 9 is set on the base 1. The outside of the placement groove 9 is provided with a clamping component 10. The clamping component 10 is used to clamp and fix the mixing container to improve the mixing stability. The clamping component 10 is connected to a linkage component 11. The linkage component 11 is used to convert the linear motion of the top seat 3 into the driving power of the clamping component 10. The linkage component 11 is connected to the top seat 3.

[0029] The clamping assembly 10 includes a bidirectional lead screw 101 disposed in the base 1. The rotation of the bidirectional lead screw 101 can drive the threaded sliders 102 on both sides to move synchronously in opposite directions. The bidirectional lead screw 101 is threadedly connected to two symmetrical threaded sliders 102 with opposite directions of movement. The threaded sliders 102 are used to drive the U-shaped rod 103 to achieve synchronous clamping action. The threaded sliders 102 are connected to the U-shaped rod 103. The U-shaped rod 103 is used to connect to the clamping plate 104 and transmit lateral movement power. The end of the U-shaped rod 103 is fixedly connected to the clamping plate 104.

[0030] The linkage assembly 11 includes a first sprocket 111 fixed in the middle of the bidirectional lead screw 101. The first sprocket 111 drives the bidirectional lead screw 101 to rotate synchronously. The first sprocket 111 is connected to a second sprocket 113 via a first chain 112, which transmits torque between the first sprocket 111 and the second sprocket 113. The second sprocket 113 is fixedly connected to a third sprocket 114 via a coaxial connecting rod, which enables the second sprocket 113 and the third sprocket 114 to rotate coaxially and synchronously. A fourth sprocket 116 is connected via a second chain 115. The second chain 115 transmits torque between the third sprocket 114 and the fourth sprocket 116. A gear 117 is fixedly connected to the fourth sprocket 116 via a coaxial connecting rod. The connecting rod enables the fourth sprocket 116 and the gear 117 to rotate synchronously on the same axis. A rack 118 is meshed with the gear 117. The rack 118 moves linearly with the top seat 3 and drives the gear 117 to rotate, completing the conversion from linear motion to rotational motion. The top of the rack 118 is fixedly connected to the top seat 3.

[0031] Specifically, a fixing ring 12 is provided on the outer side of the cylinder barrel of the hydraulic cylinder 2 near the top. The fixing ring 12 is used to securely install the ear plate 13. The ear plate 13 is fixedly connected to the front side of the fixing ring 12. The ear plate 13 is used to open the guide hole 14 and limit the guide rod 15. The ear plate 13 has a guide hole 14, which provides a precise sliding channel for the guide rod 15. The guide rod 15 is installed in the guide hole 14. The guide rod 15, together with the guide hole 14, ensures that the top seat 3 does not shake or deflect during the lifting process. The top end of the guide rod 15 is fixedly connected to the top seat 3.

[0032] Furthermore, the spring telescopic rod 8 includes a fixed housing 81 that is fixedly connected to the top seat 3 at the top. The fixed housing 81 provides a closed installation and accommodating space for the internal components. A movable plate 82 is provided inside the fixed housing 81. The movable plate 82 is used to limit the spring 83 and smoothly transmit the elastic force. The top of the movable plate 82 is connected to the spring 83, which provides elastic telescopic force to allow the cover plate 7 to adaptively press against the container opening of different heights. A movable rod 84 is fixedly connected to the bottom of the movable plate 82. The movable rod 84 is used to connect the cover plate 7 and transmit the telescopic action. The bottom end of the movable rod 84 passes through the fixed housing 81 and is fixedly connected to the cover plate 7.

[0033] Furthermore, the clamping plates 104 are symmetrically arranged above the base 1. The symmetrical structure ensures that the mixing container is clamped with uniform force. The inner wall of the clamping plates 104 is provided with anti-slip pads 105, which increase the contact friction and prevent the container from slipping and shifting.

[0034] It is worth noting that the side of the fourth sprocket 116 that is far away from the gear 117 is rotatably connected to the vertical plate 119 through the bearing. The vertical plate 119 provides stable rotation support for the sprocket and the gear, ensuring smooth operation of the transmission structure. The bottom end of the vertical plate 119 is fixedly connected to the base 1.

[0035] Hydraulic cylinder 2 and rotary drive mechanism 4 are existing technologies and will not be described in detail here; conventional electrical control components are provided with this utility model and are existing conventional technologies, which will not be described in detail here.

[0036] Working principle and process: The mixing container is placed in the placement groove 9 of the base 1 for initial positioning. The hydraulic cylinder 2 is activated, and its piston rod drives the top seat 3 to move downward. The guide rod 15 slides synchronously along the guide hole 14 on the ear plate 13 to ensure that the lifting and lowering process of the top seat 3 is smooth and without deflection. When the top seat 3 moves downward, the spring telescopic rod 8 first pushes the cover plate 7 to fit against the upper opening of the mixing container. The spring 83 in the fixed shell 81 is compressed and continuously applies elastic downward pressure, so that the cover plate 7 fits tightly with the container opening to form a sealing structure. At the same time, the top seat 3 drives the rack 118 to move downward synchronously. The rack 118 drives the meshing gear 117 to rotate. The gear 117 drives the fourth sprocket 116 to rotate through the connecting rod. Through the chain transmission of the second chain 115, the third sprocket 114, the second sprocket 113, the first chain 112 and the first sprocket 111, the clamping mechanism is driven. The bidirectional lead screw 101 in component 10 rotates, driving two threaded sliders 102 to move synchronously in opposite directions. The threaded sliders 102 drive the clamping plate 104 and the anti-slip pad 105 to move towards each other and clamp and fix the mixing container through the U-shaped rod 103. After the container is fixed, the rotary drive mechanism 4 on the top seat 3 is started. The rotary drive mechanism 4 drives the central shaft 5 and the dispersion disk 6 to rotate at high speed, shearing, dispersing and mixing the environmentally friendly water-based coating raw materials in the container. The cover plate 7 can effectively prevent material splashing and volatile substances from escaping. After the mixing operation is completed, the hydraulic cylinder 2 drives the top seat 3 to reset upwards. The rack 118 moves upwards and drives the linkage component 11 to reverse the transmission. The clamping plate 104 releases the mixing container synchronously. The spring telescopic rod 8 resets and drives the cover plate 7 to lift, so that the mixing container can be taken out from the placement groove 9.
