Description

Technical Field

[0001] The utility model belongs to the technical field of stone-like paint production equipment, and particularly relates to a tank type mixer for stone-like paint production. Background Technique

[0002] Stone-like paint is an exterior wall decorative paint made of synthetic resin and natural stone powder. Its decorative effect is similar to that of marble and granite. It has the characteristics of non-toxic, odorless, acid and alkali resistant, strong adhesion, not easy to fade, strong decoration, good simulation degree, strong weather resistance, excellent impermeability, etc. Stone-like paint is mainly prepared by mixing natural stone powder with raw materials such as water-based resin, pigment, filler, auxiliary agent, and solvent. It is mostly used to create a stone-like effect on the exterior wall of buildings, which can effectively prevent the erosion of the building by the harsh external environment and extend the life of the building. Therefore, it is also called liquid stone. The tank type mixer is an important production equipment required in the production of stone-like paint, mainly used for fully stirring and mixing various proportioned raw materials. Most of the existing tank type mixers have a fixed tank body. The material is fed through the tank opening at the top of the tank body, and discharged through the discharge port at the bottom of the tank body. To prevent the material from splashing during the stirring process, a top cover that can be lifted is usually provided above the tank opening. However, during discharging, due to the limitation of the caliber of the discharge port, the discharging speed is slow, and there is often a small amount of residual material at the bottom of the tank body, which cannot be discharged completely. It is necessary to extend the rotation time of the stirring shaft to assist in complete discharging, which is time-consuming and affects the production efficiency. In addition, there are also a few tank type mixers with a rotatable tank body structure. During feeding, the material is added through the tank opening at the top of the tank body; during discharging, the tank body is rotated, and the material is poured out through the tank opening at the top of the tank body; but before pouring, the worker needs to first remove the top cover above the tank opening, which is relatively troublesome to operate. Moreover, the existing tank bodies are not equipped with a diversion groove. When pouring the stone-like paint, the worker needs to plug the receiving hopper truck directly under the tank body to receive the material and then transport it to the next process. The distance between the worker and the equipment tank body is relatively close, posing a certain safety hazard. Content of the Utility Model

[0026] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments.

[0027] It should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. indicating the orientation or position relationship are all based on the drawings shown, only for the convenience of description.

[0028] Example

[0029] like Figure 1 As shown, a tank mixer for producing imitation stone paint includes a horizontally arranged base 1, a left support frame 2 and a right support frame 3 vertically fixed above the left and right ends of the base, and a tank body 4 flipably mounted between the left and right support frames.

[0030] The trough body is a U-shaped horizontal trough structure with an open top, and a gear plate 5 for driving the trough body to flip is fixedly connected to the outer side of the right end surface of the trough body; a flip motor 6 is arranged at the bottom inner side of the right support frame, and a driving gear 7 meshing with the gear plate is arranged on the output shaft of the flip motor.

[0031] The flip motor drives the gear plate to rotate through the driving gear, thereby realizing the forward tilt of the trough body, so that the evenly mixed imitation stone paint inside the trough body can be poured out forward; in addition, the drainage and diversion function of the dustpan-shaped guide trough top cover extends the pouring distance of the mixer, thereby increasing the distance between the workers and the mixer equipment, avoiding safety accidents such as collisions and squeezing.

[0032] Specifically, the flipping motor is a reduction motor with a brake to prevent the trough body from accidentally falling over during the flipping process. The driving gear and gear plate are both spur gears, and the tooth ratio of the driving gear to the gear plate is preferably 1:20-50. A larger gear ratio helps to reduce the torque load of the flipping motor and is also conducive to ensuring that the trough body flips and tilts more smoothly.

[0033] A stirring shaft 8 is arranged throughout the inside of the tank body, and a double-screw stirrer 9 is fixedly arranged on the outside of the stirring shaft, so that the stirring and mixing efficiency is higher and more uniform. In addition, inclined paddle scrapers 10 are staggeredly arranged on the side of the double-screw stirrer away from the stirring shaft. The outer end surface of the inclined paddle scraper is made of rubber material. When it rotates to the bottom of the tank body, it can rub against the inner wall of the tank body to scrape and clean the inner wall of the tank body to avoid residual imitation stone paint material.

[0034] The left and right ends of the stirring shaft are rotatably passed through the left and right end surfaces of the tank body and the middle of the gear plate through sealed bearings 11, and the left and right ends of the stirring shaft are rotatably mounted on the left and right support frames respectively through two bearing seats 12; the bearing seats are all vertical spherical bearings with seats.

[0035] A driven wheel 13 for driving the stirring shaft to rotate is coaxially sleeved on the outer side of the left end of the stirring shaft; a stirring motor 14 is arranged at the inner bottom of the left support frame, and a driving wheel 15 drivingly connected to the driven wheel is arranged on the output shaft of the stirring motor.

[0036] Specifically, the stirring motor is a reduction motor, the driving wheel and the driven wheel are both pulleys, and the driving and driven pulleys are connected by a V-belt 21 for driving the stirring shaft and the agitator to rotate and fully stir and mix the materials in the tank.

[0037] like Figure 4 As shown, a top cover 16 that can be opened sideways is arranged above the top opening of the trough body, and a left baffle 17 and a right baffle 18 are fixedly connected to the lower left and right sides of the top cover respectively. The top cover is a rectangular steel plate, and the left baffle and the right baffle are both right-angled triangular steel plates. The left and right baffles are respectively movably close to the left and right outer walls of the trough body, and the right-angled sides of the left and right baffles are respectively fixedly welded to the left and right sides of the top cover, and the three together form a dustpan-shaped guide trough structure with a "凵"-shaped cross-section. When the trough body is turned over and unloaded, the front side of the trough body can be extended to play a role in drainage and diversion.

[0038] Specifically, the front side of the top cover is rotatably connected to the front side wall of the trough body through a hinge structure 22, and the rear side of the top cover is openably and closably connected to the rear side wall of the trough body through a lock structure 23, so as to realize a flip-up side opening method of the slot top cover; the hinge structure and the lock structure are conventional structures in the prior art, and the specific settings will not be repeated here.

[0039] like Figures 2-3 As shown, a retractable and foldable connecting rod support 19 is connected between the left and right side edges of the top cover and the left and right end surfaces of the trough body, which is used to prevent the top cover from collapsing during the material pouring and diversion process. When pouring materials, there is no need to stuff the receiving hopper cart directly under the trough body, but only need to push it to the place where the top cover in front of the trough body can reach. The imitation stone paint material can flow into the receiving hopper cart along the dustpan-shaped top cover, which helps to increase the safe distance between the workers and the trough mixer and improve the work safety factor.

[0040] Specifically, the connecting rod support is composed of multiple connecting rods that are hinged in sequence, and the two ends of the connecting rod support are hingedly connected to the top cover and the tank body through hinge seats 24. When the top cover is closed, the connecting rod support is in a folded and contracted state; when the imitation stone paint is poured, the top cover is opened to the maximum limit, the connecting rod support is stretched straight, and at the same time, the top cover is pulled to prevent the top cover from being crushed.

[0041] An electric control box 20 is arranged on the side of the base, and a control circuit is arranged in the electric control box. The flip motor and the stirring motor are both electrically connected to the electric control box. The electrical control of the tank mixer adopts the existing technology, and the specific settings are not repeated here.

[0042] The technical solution of the present utility model is not limited to the limitations of the above specific embodiments. Without departing from the scope and spirit of the described embodiments, many modifications and changes are obvious to those of ordinary skill in the art. Any technical deformation made within the spirit and principle of the present utility model falls within the protection scope of the present utility model.
