Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing technology, specifically a high-speed mixing device for color masterbatch processing. Background Technology

[0002] Color masterbatch, also known as color concentrate or colorant, is a new type of special colorant for polymer materials. It consists of an extraordinary amount of pigment (organic or inorganic), carrier resin (such as PE, PP, etc.) and additives (such as dispersants). By highly concentrating the pigment in the resin carrier to form aggregates (pigment concentrate), the coloring power is significantly higher than that of the pigment itself.

[0003] In some color masterbatch processing, pigments, color powders, carrier resins, and additives need to be mixed. Among these, the color powders and resins account for the largest proportion. Because resins have mobile viscosity, current mixing equipment often only uses stirring when mixing with color powders. This method has low mixing efficiency and the color powders are prone to clump in the resin during mixing, affecting the mixing effect and the production quality of color masterbatches. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed mixing device for color masterbatch processing, so as 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 chamber and a resin extrusion chamber are mounted on a support base at the top of the support base. A premixing mechanism is connected to one side of the mixing chamber. A discharge pipe is connected to one side of the resin extrusion chamber. An internally threaded frame is connected to the top of the discharge pipe. A color powder feeding mechanism is connected to the top of the internally threaded frame. Multiple sets of compression pipes are connected between the discharge pipe and the premixing mechanism. A mixing motor is connected to the top of the mixing chamber. The output end of the mixing motor extends into the mixing chamber and is connected to a stirring frame. A pushing cylinder is connected to one side of the resin extrusion chamber. The output end of the pushing cylinder extends into the resin extrusion chamber and is connected to a pressure piston. A feed pipe is connected to one side of the resin extrusion chamber.

[0006] Preferably, the premixing mechanism includes a connecting pipe frame fixedly installed on one side of the mixing box, a second drive motor connected to the other side of the connecting pipe frame, a rotating shaft connected to the output end of the second drive motor, the rotating shaft extending into the connecting pipe frame and having mixing blades connected to its surface, and the end of the compression pipe away from the discharge pipe being connected and communicating with the connecting pipe frame.

[0007] Preferably, an electrically controlled valve is connected to one end of the discharge pipe near the resin extrusion chamber.

[0008] Preferably, the color powder feeding mechanism includes a color powder hopper, a connecting frame is connected to the top of the color powder hopper, a drive motor is connected to the top of the connecting frame, a feeding shaft is connected to the output end of the drive motor, and a pushing auger is connected to the bottom end of the feeding shaft.

[0009] Preferably, a connecting pipe is provided at the bottom of the color powder hopper, and the connecting pipe is threadedly connected to the internal threaded frame, with the pusher auger located inside the connecting pipe.

[0010] Preferably, the mixing box is provided with an additive addition pipe at the top and a discharge pipe at the bottom.

[0011] Preferably, one end of both the feed pipe and the discharge pipe is connected to a one-way valve.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By using a cylinder and a pressurizing piston inside the resin extrusion chamber, the resin feeding can be effectively automated. Extrusion increases the feeding speed. The color powder is fed into the high-speed flowing resin through a color powder feeding mechanism, where the resin impacts and disperses the color powder, thus mixing it. The branched compression pipe further mixes the high-speed flowing raw materials in each branch through impact, and the mixture is further mixed by a premixing mechanism. Finally, the mixture enters the mixing chamber for centralized mixing with additives, effectively improving mixing efficiency. Uniform feeding ensures good mixing effect and guarantees mixing quality. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution: including a support base 1, a mixing box 2 and a resin extrusion chamber 3 mounted on the top of the support base 1, a premixing mechanism connected to one side of the mixing box 2, a discharge pipe 5 connected to one side of the resin extrusion chamber 3, an internal threaded frame 6 connected to the top of the discharge pipe 5, a color powder feeding mechanism connected to the top of the internal threaded frame 6, multiple sets of compression pipes 12 connected between the discharge pipe 5 and the premixing mechanism, a mixing motor 16 connected to the top of the mixing box 2, the output end of the mixing motor 16 extending into the mixing box 2 and connected to a stirring frame 17, a pushing cylinder 19 connected to one side of the resin extrusion chamber 3, the output end of the pushing cylinder 19 extending into the resin extrusion chamber 3 and connected to a pressure piston 20, a feeding pipe 21 connected to one side of the resin extrusion chamber 3, and a resin source connected to the other end of the feeding pipe 21;

[0020] Reference Figure 3 As shown, the premixing mechanism includes a connecting pipe frame 4 fixedly installed on one side of the mixing box 2. A second drive motor 13 is connected to the other side of the connecting pipe frame 4. A rotating shaft 14 is connected to the output end of the second drive motor 13. The rotating shaft 14 extends into the connecting pipe frame 4 and a mixing blade 15 is connected to its surface. The end of the compression pipe 12 away from the discharge pipe 5 is connected to the connecting pipe frame 4. Before the resin mixed with the color powder enters the connecting pipe frame 4 through the compression pipe 12, the second drive motor 13 is started. The rotating shaft 14 drives the mixing blade 15 to rotate rapidly, preferentially mixing the material entering the connecting pipe frame 4. The rotation direction of the mixing blade 15 pushes the material towards the inside of the connecting pipe frame 4, further generating extrusion pressure on the material.

[0021] Reference Figure 1 and Figure 2 As shown, an electrically controlled valve 22 is connected to one end of the discharge pipe 5 near the resin extrusion chamber 3. When the electrically controlled valve 22 is closed, the cylinder 19 is pushed to contract, which drives one end of the pressure piston 20 to draw resin into the resin extrusion chamber 3 through the feed pipe 21. After a certain amount is drawn, the cylinder 19 is pushed to extend and push the pressure piston 20 to pressurize the resin. After a certain pressure is reached, the electrically controlled valve 22 is opened, and the resin will be squeezed into each compression pipe 12 at a relatively fast speed. By controlling the opening and closing degree of the electrically controlled valve 22, the flow rate and pressure can also be controlled.

[0022] Reference Figure 2 and Figure 3 As shown, the color powder feeding mechanism includes a color powder hopper 7, a connecting frame 8 connected to the top of the color powder hopper 7, a drive motor 9 connected to the top of the connecting frame 8, a feeding shaft 10 connected to the output end of the drive motor 9, and a pushing auger 11 connected to the bottom end of the feeding shaft 10. When color powder is put into the color powder hopper 7, the drive motor 9 is started, and the feeding shaft 10 drives the pushing auger 11 to rotate, which can push and squeeze the color powder inside into the discharge pipe 5, and enter the compression pipe 12 together with the squeezed resin.

[0023] Reference Figure 3 As shown, a connecting pipe is provided at the bottom of the color powder hopper 7, and the connecting pipe is threadedly connected to the internal threaded frame 6. The pusher auger 11 is located inside the connecting pipe. Through the connection between the connecting pipe and the internal threaded frame 6, it is easy to disassemble the color powder feeding mechanism as a whole for cleaning.

[0024] Reference Figure 1 and Figure 2 As shown, the top of the mixing tank 2 is connected to an additive addition pipe 23, and the bottom is connected to a discharge pipe 18. Other additives with a small proportion can be added through the additive addition pipe 23. After mixing, the mixture is discharged through the discharge pipe 18. One-way valves are connected to one end of the feed pipe 21 and the discharge pipe 18 to ensure the feeding and discharging effect.

[0025] The implementation principle of this application is as follows: When this utility model is in use, the contraction of the cylinder 19 drives the pressurizing piston 20 to move in the resin extrusion chamber 3, and the resin raw material is drawn in through the feed pipe 21. The color powder is put into the color powder hopper 7. After the resin is extracted, the cylinder 19 is extended to push the pressurizing piston 20 to extrude the resin. Then, the one-way valve 22 is opened and the drive motor 9 is started at the same time, which drives the pusher auger 11 to rotate and push the color powder to be discharged. The resin flowing out at high speed will carry the color powder into each compression pipe 12 and converge in the connecting pipe frame 4. As the raw materials flowing at high speed in each compression pipe 12 converge in the connecting pipe frame 4, they are initially mixed. At the same time, the drive motor 13 is started to drive the mixing blade 15 to rotate and stir the raw materials impacting the connecting pipe frame 4. Finally, the premixed material is discharged into the mixing box 2. The mixing motor 16 is started and the final mixing is carried out through the stirring rack 17. At the same time, the additives can be injected into the mixing box 2 through the additive addition pipe 23.
