Description

Technical Field

[0001] This utility model belongs to the field of plastic running track production technology, and in particular to a device for mixing plastic powder and calcium carbonate. Background Technology

[0002] In the production process of plastic running tracks, a mixing device is required to stir and mix the rubber powder and calcium carbonate powder. At the same time, curing agents, catalysts and diluents need to be added. Existing mixing devices often directly introduce the rubber powder and calcium carbonate powder into the mixing tank, which makes it difficult to control the position of the rubber powder and calcium carbonate powder introduced into the mixing tank. This results in uneven distribution of the rubber powder and calcium carbonate powder in the mixing tank, reducing the mixing efficiency of the device.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN222606159U) describing a calcium carbonate powder mixing and stirring device. This device includes a first mixing chamber, with a second mixing chamber fixedly mounted at the bottom of the first mixing chamber via a fixed pipe. The interiors of both the first and second mixing chambers are equipped with mixing and stirring mechanisms via a dual-shaft motor. A first stirring paddle drives a rotating plate to rotate. Through the cooperation of the rotating plate and the fixed pipe, calcium carbonate powder and additives intermittently fall onto a movable cover. This allows the movable cover to fully disperse the calcium carbonate and additives under the action of a spring and a sliding rod. By repeatedly mixing and stirring the calcium carbonate powder and additives through the first mixing chamber and the first stirring paddle, and the second mixing chamber and the second stirring paddle, the mixing efficiency of calcium carbonate and additives can be improved, ensuring uniformity of mixing and high practicality. However, this device is not convenient for controlling the position of the adhesive powder and calcium carbonate powder introduced into the mixing tank, resulting in uneven distribution of the adhesive powder and calcium carbonate powder within the mixing tank, reducing the mixing efficiency of the device for the adhesive powder and calcium carbonate powder. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for calcium carbonate and adhesive powder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for colloid powder and calcium carbonate, comprising:

[0006] A mixing tank for mixing calcium carbonate powder has a hollow bottom. The inner cavity of the mixing tank is equipped with a hollow connecting shell. A stirring rod is welded to the bottom surface of the connecting shell. Several stirring plates for mixing calcium carbonate powder are connected to the side of the stirring rod.

[0007] Two fixed plates are provided, with feed hoppers welded to their top surfaces. An L-shaped feed pipe is rotatably connected to the bottom surface of the feed hoppers via bearings. A mounting plate is welded to the side of the mixing tank, and a rotary motor is mounted on the top surface of the mounting plate. The output shaft of the rotary motor is connected to a pulley two via a coupling. A belt is provided on the side of the pulley two, and a pulley one is provided on the inner wall of the belt. The top surface of the pulley one is embedded and fixedly connected to the feed pipe.

[0008] Preferably, the bottom surfaces of the two fixed plates are welded to the mixing tank, and the top surface of the mixing tank is rotatably connected to the feed pipe via a bearing.

[0009] Preferably, the top and side surfaces of the connecting shell are both embedded and fixedly connected to the feed pipe, and the bottom surface of the mixing tank is welded with a discharge hopper.

[0010] Preferably, a discharge pipe with a solenoid valve is installed on the bottom surface of the discharge hopper, and four support rods arranged at equal angles on the side of the discharge pipe are provided to support the discharge hopper.

[0011] Preferably, a mixing component is provided on the top surface of the discharge hopper, the mixing component including a telescopic inner rod and a telescopic outer rod with a hollow interior.

[0012] Preferably, the top surface of the telescopic outer rod is connected to the stirring rod, and a square-shaped limiting plate is slidably connected to the inner cavity of the telescopic outer rod.

[0013] Preferably, a spring is provided on the top surface of the limiting plate, and the bottom surface of the limiting plate is fixedly connected to the telescopic inner rod.

[0014] Preferably, the bottom surface of the telescopic inner rod is connected to a mixing plate that fits with the inclined surface of the discharge hopper.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] When this rubber powder and calcium carbonate mixing device directly introduces rubber powder and calcium carbonate powder into the mixing tank, the rubber powder and calcium carbonate powder are prone to accumulate in a fixed position in the mixing tank, reducing the uniform distribution of the rubber powder and calcium carbonate powder in the mixing tank. The set of rotary motor provides power, and under the connection of pulley two, belt and pulley one, the feed pipe is rotated. The rubber powder and calcium carbonate powder are introduced into the feed pipe through the feed hopper. The rotating feed pipe introduces rubber powder and calcium carbonate powder into different positions in the mixing tank, which can make the rubber powder and calcium carbonate powder uniformly distributed in the mixing tank and improve the mixing efficiency of the device. The distribution position of rubber powder and calcium carbonate powder can be controlled by controlling the rotation speed of the feed pipe. The transverse inner cavity of the feed pipe is relatively short, which does not affect the introduction of rubber powder and calcium carbonate powder into the bottom of the feed pipe.

[0017] This rubber powder and calcium carbonate mixing device, with the connection between the housing and the stirring rod, allows several stirring plates to rotate around the stirring rod as the axis, mixing the rubber powder and calcium carbonate powder. To facilitate the output of the mixed rubber powder and calcium carbonate powder from the mixing tank, the discharge hopper is designed with an inwardly concave inclination, which facilitates the output of the rubber powder and calcium carbonate powder, but makes it difficult for the stirring plates to mix the rubber powder and calcium carbonate powder in the discharge hopper. The mixing component can mix the rubber powder and calcium carbonate powder in the discharge hopper. The spring provides elastic thrust, causing the limiting plate to move along the inner cavity of the telescopic outer rod. With the connection of the telescopic inner rod, the mixing plate is tightly attached to the discharge hopper, enhancing the mixing effect of the rubber powder and calcium carbonate powder in the discharge hopper.

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] Please see Figures 1 to 4 A mixing device for rubber powder and calcium carbonate, in this embodiment, includes:

[0029] The mixing tank 1 for mixing rubber powder and calcium carbonate has a hollow bottom. The inner cavity of the mixing tank 1 is provided with a hollow connecting shell 4. A stirring rod 10 is welded to the bottom surface of the connecting shell 4. Several stirring plates 11 for mixing rubber powder and calcium carbonate are connected to the side of the stirring rod 10. When the several stirring plates 11 rotate around the stirring rod 10 as the axis, the rubber powder and calcium carbonate powder located in the mixing tank 1 can be stirred and mixed.

[0030] Two fixed plates 12 are provided, with a feed hopper 2 welded to the top surface of each plate. An L-shaped feed pipe 3 is rotatably connected to the bottom surface of the feed hopper 2 via a bearing. A mounting plate 9 is welded to the side of the mixing tank 1, and a rotary motor 8 is mounted on the top surface of the mounting plate 9. The fixed end of the rotary motor 8 is connected to the mounting plate 9 via bolts. The output shaft of the rotary motor 8 is connected to a pulley 7 via a coupling. A belt 6 is provided on the side of the pulley 7, and a pulley 5 is provided on the inner wall of the belt 6. The top surface of the pulley 5 is embedded and fixedly connected to the feed pipe 3. The two ends of the inner wall of the belt 6 are respectively tumblingly connected to the pulley 5 and the pulley 7. When the pulley 7 rotates, the pulley 5 rotates under the connection of the belt 6. During the transmission process, the feed pipe 3 can rotate, which can alternately introduce adhesive powder and calcium carbonate powder into the feed hopper 2. At the same time, during the rotation of the feed pipe 3, the introduced adhesive powder and calcium carbonate powder can be evenly distributed in the mixing tank 1, improving the mixing efficiency of the device for adhesive powder and calcium carbonate powder.

[0031] Two fixed plates 12 are welded to the bottom of the mixing tank 1. The top of the mixing tank 1 is rotatably connected to the feed pipe 3 via bearings. The top and sides of the connecting shell 4 are embedded and fixedly connected to the feed pipe 3. The transverse pipe of the feed pipe 3 is relatively short, providing conditions for the introduction of adhesive powder and calcium carbonate powder into the lower part of the feed pipe 3 inside the mixing tank 1. The position of the adhesive powder and calcium carbonate powder in the mixing tank 1 can be controlled by adjusting the rotation speed of the feed pipe 3. A discharge hopper 13 is welded to the bottom of the mixing tank 1. The top surface of the discharge hopper 13 is concave and inclined. A discharge pipe 14 with a solenoid valve is installed on the bottom surface of the discharge hopper 13. Four support rods 15 arranged at equal angles are provided on the side of the discharge pipe 14 to support the discharge hopper 13. The top surfaces of the four support rods 15 are connected to the discharge hopper. 13 Welding: A mixing component 16 is provided on the top surface of the discharge hopper 13. The mixing component 16 includes a telescopic inner rod 19 and a hollow telescopic outer rod 17. The top surface of the telescopic outer rod 17 is connected to the stirring rod 10. A square-shaped limiting plate 20 is slidably connected to the inner cavity of the telescopic outer rod 17. A spring is provided on the top surface of the limiting plate 20. The top surface of the spring is welded to the inner top wall of the telescopic outer rod 17. The spring is a high-strength spring to prevent frequent vibration during use, improve the structural stability of the device's components, and provide buffering for the damper installed in the inner cavity of the spring, further improving the structural stability of the device's components. The bottom surface of the limiting plate 20 is fixedly connected to the telescopic inner rod 19. A mixing plate 18 that fits the inclined surface of the discharge hopper 13 is connected to the bottom surface of the telescopic inner rod 19.

[0032] To improve mixing efficiency, rubber powder and calcium carbonate powder can be alternately introduced into the feed hopper 2. The rotary motor 8 is started, and the output shaft of the rotary motor 8 drives the pulley 7 to rotate. With the connection of the belt 6 and the pulley 5, the feed pipe 3 rotates, so that the feed pipe 3 evenly introduces rubber powder and calcium carbonate powder into the mixing tank 1, thereby improving the mixing efficiency of rubber powder and calcium carbonate powder. At the same time, the feeding position in the mixing tank 1 can be controlled by controlling the rotation speed of the feed pipe 3.

[0033] To facilitate mixing, the stirring rod 10 rotates synchronously and in the same direction as the feed pipe 3, connected to the housing 4. This causes several stirring plates 11 to rotate around the stirring rod 10 as the axis, thus mixing the adhesive powder and calcium carbonate powder. To facilitate the discharge of the adhesive powder and calcium carbonate powder after mixing, the top surface of the discharge hopper 13 is concave and inclined, allowing the material to be discharged through the discharge pipe 14 under gravity. Since the top surface of the discharge hopper 13 is inclined, the stirring plates 11 are not convenient for mixing the adhesive powder and calcium carbonate powder. The spring provides elastic thrust, causing the limiting plate 20 to move down along the inner cavity of the telescopic outer rod 17. With the connection of the telescopic inner rod 19, the mixing plate 18 and the discharge hopper 13 are in close contact, enhancing the mixing effect of the device on the adhesive powder and calcium carbonate powder.

[0034] The rotary motor 8 and the solenoid valve are existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0035] The working principle of this utility model:

[0036] When feeding, the rubber powder and calcium carbonate powder are alternately introduced into the feed hopper 2, and the rubber powder and calcium carbonate powder are introduced into the mixing tank 1 through the feed pipe 3. The rotary motor 8 is started, and the feed pipe 3 is rotated under the connection of pulley 2 7, belt 6 and pulley 1 5, so that the introduced rubber powder and calcium carbonate powder are evenly distributed in the mixing tank 1.

[0037] When stirring, the connection between the housing 4 and the stirring rod 10 causes several stirring plates 11 to rotate around the stirring rod 10 as the axis, stirring and mixing the adhesive powder and calcium carbonate powder. Under the elastic thrust provided by the spring, the limiting plate 20 and the telescopic inner rod 19 move down along the inner cavity of the telescopic outer rod 17, so that the mixing plate 18 and the discharge hopper 13 are in close contact, thereby enhancing the stirring and mixing effect of the adhesive powder and calcium carbonate powder.
