Description

Technical Field

[0001] This utility model belongs to the technical field of water-based paint production equipment, specifically relating to a water-based paint dispersion device for steel templates. Background Technology

[0002] Water-based paint is a coating that uses water as a solvent or a dispersion medium. Compared with oil paint, water-based paint is safer and more environmentally friendly. It is water-resistant, wear-resistant, aging-resistant, dries quickly, and is easy to use. Moreover, the production cost of water-based paint is relatively low. Therefore, water-based paint is often used as an anti-corrosion coating for steel formwork.

[0003] A crucial step in the production process of water-based paints is the dispersion process, which involves using a dispersion device to mix water-based resins, film-forming aids, defoamers, pigments, and other raw materials with water. However, existing water-based paint dispersers have relatively simple structures and functional designs, and some inconveniences still exist in actual production, requiring urgent improvement and refinement. For example:

[0004] 1. Some existing dispersers lack a material barrel fixing device. Because the water-based paint solution in the barrel has a certain viscosity, when the disperser rotates and stirs at high speed, there is a tendency for the material barrel to shift. Once the material barrel shifts, the inner wall of the barrel may come into contact with the high-speed rotating dispersing head, which may cause a safety risk. Some dispersers are equipped with simple material barrel fixing devices, usually hand-cranked screw clamps or strap tensioners, which are very inconvenient to tighten and affect work efficiency.

[0005] 2. Existing dispersers have poor compatibility with material tanks. Material tanks can be cylindrical with a completely open top or constricted at the top and bottom. The dispersing head of a disperser is typically a horizontal, toothed disc. Its mixing range is a vortex that gradually expands from the center outwards. For larger diameter open tanks, the mixing speed decreases further away from the center, requiring longer mixing times and thus affecting dispersing efficiency. Furthermore, the mixing process can easily cause material to splash out. On the other hand, if the diameter of the dispersing head is increased, it may not be able to fit into smaller diameter constricted tanks, creating a contradictory problem. Utility Model Content

[0006] In response to the above situation, this utility model provides a steel template water-based paint dispersion device, which improves the adaptability of the disperser to the shape of the material bucket, and makes the tight fixing and positioning of the material bucket simpler and more convenient.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A water-based paint dispersion device for steel formwork, comprising a horizontally arranged base, a lifting column vertically fixed above the base, and a power head that can be lifted and horizontally suspended at the top of the lifting column. A dispersion motor is arranged at the front end of the power head, and a dispersion head that can lift in and out of the feed barrel is connected by a rotating shaft below the dispersion motor. The base is a "C"-shaped structure with an open front, and the lifting column is a hydraulic cylinder. A hydraulic station is arranged on the base in cooperation.

[0009] On the lower front side of the outer wall of the hydraulic cylinder, a horizontally arranged linear module is fixedly connected. A left-right threaded screw is rotatably arranged in the middle of the linear module. A telescopic slide is arranged on the front side of each of the left and right ends of the left-right threaded screw. A guiding slide rod for guiding the telescopic slide is fixedly arranged on each of the upper and lower sides of the left-right threaded screw. On the front side of the two telescopic slides, a left clamping arm and a right clamping arm for clamping the feed barrel are symmetrically arranged in a "C" shape. A clamping motor for driving the left-right threaded screw to rotate is arranged at one end of the linear module.

[0010] The dispersion head consists of a dispersion disk fixedly connected to the lower end of the rotating shaft and a shear disk coaxially fixedly connected above the dispersion disk. Both the dispersion disk and the shear disk are disk-shaped structures. Upward-bent upper teeth and downward-bent lower teeth are respectively arranged at intervals around the upper and lower sides of the outer edge of the dispersion disk. A circle of eagle-beak-shaped shear knives is radially arranged at intervals around the outer edge of the shear disk. A plurality of stirring paddles are evenly hung on the outside of the rotating shaft above the shear disk. One end of each stirring paddle close to the rotating shaft is rotatably hinged to the outer wall of the rotating shaft through a hinge seat.

[0011] A circular feed barrel cover is surrounded and arranged around the upper outer periphery of the rotating shaft, which is used to cover above the barrel mouth of the feed barrel to prevent the material liquid from splashing. The upper surface of the feed barrel cover is suspended below the power head through a telescopic spring coaxially sleeved around the rotating shaft.

[0012] Further, universal wheels with brakes are respectively arranged below the four corners of the base, which is convenient for the movement and positioning of the entire dispersion device.

[0013] Further, a triangular reinforcing rib plate is arranged in cooperation around the connection between the bottom of the hydraulic cylinder and the base, which is used to reinforce the stability of the vertical column of the hydraulic cylinder. The hydraulic cylinder is a hydraulic cylinder with a guide.

[0014] Further, V-shaped rubber clamping claws are fixedly arranged on the inner sides of the fronts of the left clamping arm and the right clamping arm, which improves the clamping friction force for the feed barrel.

[0015] Further, the rotating shaft rotatably passes through the center of the inner circle of the feed barrel cover. An elastic rubber sheet is arranged in a ring between the inner circle edge of the feed barrel cover and the outer wall of the rotating shaft, which is used to flexibly seal the inner circle of the feed barrel cover. A flexible rubber ring is arranged in a ring around the outer circle edge of the feed barrel cover, which is used to flexibly seal the outer edge of the feed barrel cover.

[0016] Furthermore, the material bucket cover is also provided with an observation port, and an openable upper cover is provided on the observation port. One side of the upper cover is rotatably connected to one side of the observation port via a hinge, and a lifting handle is provided on the other side of the upper cover.

[0017] Furthermore, the hydraulic station includes a hydraulic oil tank, and a hydraulic oil pump and hydraulic valve assembly fixedly mounted on the hydraulic oil tank. A control box is located outside the hydraulic cylinder, and the hydraulic oil pump, hydraulic valve assembly, dispersing motor, and clamping motor are all electrically connected to the control box. The lifting and lowering of the hydraulic cylinder is achieved by controlling the hydraulic oil pressure of the hydraulic oil pump and the hydraulic valve assembly.

[0018] This utility model also includes other components that enable its normal use, all of which are conventional means in the field. In addition, devices or components not limited in this utility model, such as hydraulic cylinders, hydraulic stations, power heads, and dispersing heads, all adopt existing technologies in the field.

[0019] The beneficial effects of this utility model are as follows:

[0020] The steel template water-based paint dispersing device provided by this utility model uses expandable left and right clamping arm structures to clamp and fix the material barrel, effectively avoiding safety hazards caused by barrel displacement. Based on the traditional dispersing head, it further adds a shearing blade, a hanging stirring paddle that can be gravity-driven and centrifugally opened, and a liftable elastic barrel cover, which can better improve the stirring and dispersing capacity and efficiency. On the one hand, when the stirring paddle is open, it can better adapt to the large-scale rapid stirring and dispersion of materials in the large-diameter barrel; on the other hand, when the stirring paddle is lowered, it will not affect the smooth entry and exit of the small-diameter barrel opening of the constricted barrel. This achieves two goals at once and effectively solves the contradictory compatibility and applicability problems of existing dispersers. Attached Figure Description

[0029] Embodiment

[0030] As Figure 1-5 shown, a water-based paint dispersion device for steel templates includes a horizontally arranged base 1, a lifting column 2 vertically fixed above the base, and a power head 3 that can be lifted and horizontally suspended at the top of the lifting column. A dispersion motor 4 is provided at the front end of the power head. A dispersion head that can lift in and out of the material barrel 33 is connected by a rotating shaft 5 under the dispersion motor. The base is a "U" - shaped structure with an open front. The lifting column is a hydraulic cylinder, and a hydraulic station is arranged in cooperation with the base.

[0031] A horizontally arranged linear module 6 is fixedly connected to the lower front side of the outer wall of the hydraulic cylinder. A left - right thread screw rod 7 is rotatably arranged in the middle of the linear module through a bearing. A telescopic slide 8 is provided on the front side of each of the left and right ends of the left - right thread screw rod. A guiding slide rod 9 for guiding the telescopic slide is fixedly arranged on the upper and lower sides of the left - right thread screw rod respectively. A left clamping arm 10 and a right clamping arm 11 for clamping the material barrel are symmetrically arranged in a "U" - shaped manner on the front side of the two telescopic slides. A clamping motor 12 for driving the left - right thread screw rod to rotate is arranged at one end of the linear module.

[0032] The dispersing head consists of a dispersing disc 13 fixed to the lower end of the rotating shaft and a shearing disc 14 coaxially fixed above the dispersing disc by connecting bolts. Both the dispersing disc and the shearing disc are disc-shaped structures. The upper and lower sides of the circumference of the dispersing disc are respectively provided with upward-bent upward teeth 15 and downward-bent downward teeth 16 at intervals. The dispersing disc and its upward and downward teeth are conventional designs of existing dispersing heads and will not be described in detail here. The outer side of the circumference of the shearing disc is provided with a ring of beak-shaped shearing blades 17 at radial intervals. This is an additional configuration of the dispersing head to improve the high-speed dispersing and shearing capability of the dispersing head. Multiple shearing blades are also evenly suspended on the outer side of the rotating shaft above the shearing disc. When the rotating shaft is not rotating and lifting, the agitator 18 hangs down under its own weight to avoid affecting the position of the rotating shaft entering and exiting the small-diameter opening of the narrow-mouthed material tank. The end of each agitator near the rotating shaft is rotatably connected to the outer wall of the rotating shaft via a hinge seat 19. When the rotating shaft rotates at high speed, the agitator opens under the action of centrifugal force to expand the mixing coverage area, accelerate the stirring of the liquid near the tank wall of the large-diameter material tank, and improve the mixing and dispersion efficiency of the rotating shaft. Similarly, if the height of the rotating shaft and the material tank allows, more agitator assemblies can be set on the rotating shaft to further improve the mixing and dispersion efficiency.

[0033] The upper outer periphery of the rotating shaft is surrounded by an annular material bucket cover 20, which is used to cover the opening of the material bucket to prevent the material liquid from splashing. The upper surface of the material bucket cover is suspended below the power head by a telescopic spring 21 coaxially sleeved around the rotating shaft.

[0034] The base is equipped with four casters 22 with brakes at its lower corners.

[0035] A triangular reinforcing rib plate 23 is provided around the outer periphery of the connection between the bottom of the hydraulic cylinder and the base. The hydraulic cylinder is a guided hydraulic cylinder, and a guide bar 24 is provided to guide its piston rod to extend and retract axially and prevent circumferential rotation of the piston rod during the extension and retraction process.

[0036] The front inner sides of the left and right clamping arms are also fixedly provided with V-shaped rubber claws 25 to increase the clamping friction of the material bucket and ensure the stability of the material bucket clamping.

[0037] The rotating shaft rotatably passes through the center of the inner circle of the bucket lid. A fan-shaped elastic rubber sheet 26 is arranged around the inner edge of the bucket lid and the outer wall of the rotating shaft. The outer wall of the rotating shaft rotates and rubs against the inner edge of the elastic rubber sheet to flexibly seal the inner circle of the bucket lid. A flexible rubber ring 27 is arranged around the outer edge of the bucket lid to flexibly seal the outer edge of the bucket lid. When the bucket is an open bucket, after the power head descends, the bucket lid is elastically pressed onto the bucket opening under the action of the telescopic spring, and the flexible rubber ring flexibly abuts against the upper edge of the bucket opening.

[0038] The material bucket lid is also provided with an observation port, and an openable upper cover 28 is provided on the observation port. One side of the upper cover is rotatably connected to the side of the observation port via a hinge, and a lifting handle is provided on the other side of the upper cover. The observation port can be used to observe the condition inside the material bucket, and can also be used as an addition port for adding auxiliary materials into the material bucket.

[0039] The hydraulic station includes a hydraulic oil tank 29, and a hydraulic oil pump 30 and a hydraulic valve assembly 31 fixedly installed on the hydraulic oil tank. A control box 32 is provided on the outside of the hydraulic cylinder, and the hydraulic oil pump, hydraulic valve assembly, dispersing motor and clamping motor are all electrically connected to the control box.

[0040] The lifting and lowering of the hydraulic cylinder is achieved by controlling the hydraulic pressure through a hydraulic oil pump and a hydraulic valve assembly. A speed regulator (not shown in the figure) is also installed inside the control box, which can appropriately adjust the speed of the dispersing motor and the dispersing head.

[0041] Pressure sensors (not shown in the figure) are also installed between the left and right clamping arms and their corresponding rubber grippers. These sensors transmit the clamping pressure signal of the material barrel to the controller, which then controls the start and stop of the clamping motor, thereby controlling the clamping force of the material barrel.

[0042] The working principle of this utility model is as follows:

[0043] When this steel template water-based paint dispersion device performs dispersion operations, the container holding the water-based paint to be dispersed is first placed in the open space in the middle of the base through the "U"-shaped opening. Then, the clamping motor drives the left and right clamping arms and two rubber grippers to gradually retract and clamp the container. From the moment the inner "V"-shaped sides of the grippers contact the container, the pressure sensors between the grippers and the clamping arms begin transmitting the detected pressure signal to the controller. This continues until the pressure signal reaches the pressure threshold set by the controller, at which point the clamping arms and grippers stop clamping and pressurizing the container. This pressure threshold is determined by on-site personnel based on the actual batch of water-based paint's concentration, viscosity, and other product specifications. The required clamping force is determined based on production experience, taking into account the size of the material bucket and the amount of liquid inside. The goal is to ensure a stable clamping without damaging or deforming the bucket. This is standard practice and selection for those skilled in the art, and will not be elaborated upon here. After the bucket is securely clamped, the hydraulic cylinder lifting column begins to drive the power head to slowly descend until the lower end of the rotating shaft and the middle drooping agitator are fully inside the bucket and reach the set height. Then, the dispersion motor drives the dispersion head and agitator to rotate and agitate the water-based paint liquid inside the bucket until it is evenly dispersed. Finally, the dispersion head is raised and withdrawn, completing the dispersion operation. The coordinated control of the clamping arm's extension and retraction to clamp the bucket and the hydraulic cylinder's driving of the power head's lifting and lowering is performed by on-site personnel based on actual needs and experience. This is also standard practice and selection for those skilled in the art, and will not be elaborated upon here.

[0044] The technical solution of this utility model is not limited to the specific embodiments described above. Without departing from the scope and spirit of the described embodiments, many modifications and changes will be obvious to those skilled in the art. Any technical modifications made within the spirit and principles of this utility model shall fall within the protection scope of this utility model.
