Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a multi-head mixing machine. Background Art

[0002] Plastic pellets are made from old or waste plastics that are melted at high temperature in a material making machine and then cooled. After the plastic pellets are formed, they are transported to another factory, where the plastic pellets are melted again and placed in a gear pump, and then processed by the gear pump to form plastic wires or plastic plates. Since the plastic needs to be heated and melted first, then cooled to form plastic pellets, and then melted and placed in a gear pump, this process wastes a lot of energy, is uneconomical, environmentally friendly, and costly. At the same time, the plastic is melted twice, which reduces its performance. In the process of forming plastic pellets from old or waste plastics, the pressure and flow of the molten plastic in the conveying pipe are unstable. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a multi-head mixing machine in view of the deficiencies in the prior art.

[0004] In order to solve the above technical problems, the present utility model adopts the following technical solutions.

[0005] A multi-head mixer includes at least one conveying pipeline, a material mixing device, a material diversion pipeline, and several gear pumps; the material mixing device is used to convey materials into the conveying pipeline, the conveying pipeline is provided with a twin-screw that drives the material to move from the feed end to the discharge end, the discharge end of the conveying pipeline is connected to the material diversion pipeline, the material diversion pipeline is provided with several discharge ports, and each discharge port is connected to a gear pump.

[0006] A preferred solution is to provide a first valve between the discharge end of the conveying pipeline and the material diversion pipeline.

[0007] A preferred solution is to provide a second valve between the discharge port and the gear pump.

[0008] A preferred solution is that a heating wire is provided in the gear pump.

[0009] A preferred solution is that the material diversion pipeline is provided with several sections, adjacent sections are detachably connected, and each section is provided with a discharge port.

[0010] A preferred solution is that a motor is provided at one end of the conveying pipeline, and the motor drives the twin screws to rotate.

[0011] A preferred solution is that the gear pump includes: a pump housing, a first gear and a second gear; the first gear and the second gear are rotatably arranged in the pump housing.

[0012] The multi-head mixer provided by the present invention has at least the following beneficial effects: plastic particles are placed in a material mixing device, enter a conveying pipe, and melt within the conveying pipe. The molten plastic moves along a twin screw from the feed end to the discharge end of the conveying pipe, enters a material diversion pipe, and remains molten. The molten plastic enters a gear pump through a plurality of discharge ports, and the gear pump discharges plastic strands or sheets of predetermined shapes. Because the plastic remains molten before forming the plastic strands or sheets, the molten plastic does not need to be cooled and transported to the next factory to form the plastic strands or sheets, thereby reducing costs, being economical and environmentally friendly. Because the twin screws uniformly convey the molten plastic into the material diversion pipe, the pressure and flow rate of the plastic within the material diversion pipe are relatively stable. When the molten plastic flows to the gear pump, the plastic strands or sheets formed by the gear pump are more uniform. The plurality of discharge ports are independent of each other, and when one discharge port is shut down, it does not affect the other discharge ports, thus enabling automated production.

[0013] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In addition, in order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 6 As shown, plastic pellets are placed in a material mixing device 2, which then enters a conveying pipe 1 where they melt. The molten plastic moves along a twin-screw 5 from the feed end of the conveying pipe 1 to the discharge end. The molten plastic then enters a material diversion pipe 3 where it remains molten. The molten plastic then enters a gear pump 4 from a plurality of discharge ports 6, which discharge the plastic strands or sheets in predetermined shapes. Because the plastic remains molten until it is formed into strands or sheets, the molten plastic does not need to be cooled and can be transported to the next factory to be formed into strands or sheets, reducing costs and being economical and environmentally friendly.

[0025] like Figures 1 to 6 As shown, since the twin screws 5 evenly transport the molten plastic into the material diversion pipe 3, the pressure and flow of the plastic in the material diversion pipe are relatively stable. When the molten plastic flows to the gear pump 4, the plastic line or plastic plate formed by the gear pump 4 is more uniform.

[0026] like Figures 1 to 6As shown, the plurality of discharge ports 6 are independent of each other. When one of the discharge ports 6 stops production, it does not affect the other discharge ports 6 and the automated production can be completed.

[0028] like Figures 1 to 6 As shown, a second valve 8 is provided between the discharge port 6 and the gear pump 4. The second valve 8 can control the flow of the material diversion pipe to the gear pump 4. The gear pumps 4 are independent of each other. A second valve 8 is provided between each discharge port 6 and each gear pump 4. Some gear pumps 4 can be closed and some gear pumps 4 can be opened.

[0029] like Figures 1 to 6 As shown, a heating wire is provided in the gear pump 4. The heating wire can be heated so that the gear pump 4 is in a high temperature state, and the melted plastic in the gear pump 4 remains in a molten state.

[0030] like Figures 1 to 6 As shown, the material diversion pipeline 3 is provided with several sections, adjacent sections are detachably connected, and each section is provided with a discharge port 6. The material diversion pipeline 3 can be provided with different sections as needed. When multiple gear pumps 4 are required to work, the material diversion pipeline 3 can be lengthened. When a small number of gear pumps 4 are required to work, the material diversion pipeline 3 can be shortened, which is flexible in use.

[0031] like Figures 1 to 6 As shown, a motor 9 is provided at one end of the conveying pipe 1 , and the motor 9 drives the twin screws 5 to rotate.

[0032] like Figures 1 to 6 As shown, the gear pump 4 includes: a pump housing 10 , a first gear 11 and a second gear 12 ; the first gear 11 and the second gear 12 are rotatably disposed in the pump housing 10 .

[0033] The above is a specific implementation of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
