Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a PP material mixing and coloring mixer. Background Technology
[0002] In the processing and production of PP materials, PP granules and colorants (such as color masterbatch and color powder) need to be mixed evenly to ensure the color consistency of the finished product.
[0003] Material residue easily remains on the inner wall of the mixing tank. Disassembly and cleaning are required when changing the coloring type, which is time-consuming and labor-intensive, and can easily cause cross-contamination, increasing the workload of workers. At the same time, PP material is prone to clumping at low temperatures and softening at high temperatures. Existing equipment does not have targeted temperature control, which affects mixing efficiency and material performance. Therefore, a PP material mixing and coloring mixer is proposed to address the above problems. Utility Model Content

Support frames are installed on the left and right sides of the mixing tank, and a feeding hopper is provided on the top of the support frames. The bottom end of the feeding hopper is conductively connected to the left side of the top of the mixing tank. The top of the middle part of the mixing tank is vertically connected to the bottom of the front and rear ends of the top plate. One end of the feeding pipe is connected to an external colorant conveying pipe, and the other end passes through the top plate and connects to the inside of the mixing tank. A discharge pipe is provided at the bottom of the mixing tank, and a control valve is installed in the middle of the discharge pipe. The temperature control mechanism includes a heating chamber disposed inside the lower half side wall of the mixing tank. Heating wires are evenly arranged inside the heating chamber. A temperature sensor is installed on the inner side wall of the mixing tank.

[0006] Preferably, the front view of the mixing base plate is an arc-shaped structure, the arc of the mixing base plate is the same as the arc of the inner side of the bottom of the mixing barrel, and the bottom side of the mixing base plate is in close contact with the inner side of the bottom of the mixing barrel.
[0007] Preferably, the automatic cleaning mechanism includes an annular spray pipe, with its front and rear ends fixed inside mounting holes at the front and rear ends of the top plate. The bottom of the annular spray pipe is equipped with a nozzle, and the front end of the annular spray pipe is connected to the inside of the mixing tank via a connecting water pipe. A filter screen is installed at the connection between the connecting water pipe and the mixing tank.

[0009] Preferably, all electrical components in this invention are electrically connected to an external controller.
[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) The temperature control mechanism can accurately control the mixing temperature of materials by heating the heating wire evenly and feeding back the temperature sensor in real time, avoiding problems such as colorant failure and material clumping caused by temperature fluctuations, and ensuring the performance stability of the mixed materials.
[0011] In the mixing mechanism, multiple mixing plates achieve radial and comprehensive mixing, and the arc-shaped mixing base plate fits and scrapes the bottom of the mixing tank, completely solving the problem of "material sedimentation at the bottom without mixing". At the same time, the reinforcing plate enhances the connection strength between the rotating shaft and the mixing base plate, preventing component deformation during mixing, extending the service life of the mixing mechanism, and reducing material residue waste.
[0012] The automatic cleaning mechanism eliminates the need for manual disassembly of components. It achieves all-around cleaning coverage through a ring-shaped spray pipe and multiple nozzles, and is equipped with a filter screen to prevent clogging.

Support frames 2 are installed on the left and right sides of the mixing tank 1, and a feeding hopper 21 is provided on the top of the support frame 2. The bottom end of the feeding hopper 21 is conductively connected to the left side of the top of the mixing tank 1. The top of the middle end of the mixing tank 1 is vertically connected to the bottom of the front and rear ends of the top plate 11. One end of the feeding pipe 12 is connected to an external colorant conveying pipe, and the other end passes through the top plate 11 and connects to the inside of the mixing tank 1. A discharge pipe 13 is provided at the bottom of the mixing tank 1, and a control valve 14 is installed in the middle of the discharge pipe 13. The temperature control mechanism includes a heating chamber 51 disposed inside the lower half side wall of the mixing tank 1. Heating wires 52 are evenly arranged inside the heating chamber 51. A temperature sensor 53 is installed on the inner side of the side wall of the mixing tank 1.
[0019] The stirring mechanism includes a motor 41 installed at the top of the middle of the top plate 11. The output end of the motor 41 is connected to the top of the rotating shaft 42 via a coupling. Multiple stirring plates 43 are evenly arranged on the outer side of the middle of the rotating shaft 42. One end of the reinforcing plate 44 is connected to the outer side of the bottom of the rotating shaft 42, and the other end is connected to the inner side of the stirring base plate 45. The front view cross section of the stirring base plate 45 is an arc-shaped structure. The arc of the stirring base plate 45 is the same as the arc of the inner side of the bottom of the stirring tank 1, and the bottom side of the stirring base plate 45 is in close contact with the inner side of the bottom of the stirring tank 1.
[0020] The automatic cleaning mechanism includes an annular spray pipe 31. The front and rear ends of the annular spray pipe 31 are fixed inside the mounting holes at the front and rear ends of the top plate 11. The bottom of the annular spray pipe 31 is provided with a nozzle 32. The front end of the annular spray pipe 31 is connected to the inside of the mixing tank 35 through a connecting water pipe 34. A filter screen 36 is installed at the connection between the connecting water pipe 34 and the mixing tank 35. The front end of the mixing tank 35 is connected to the output end of the cleaning liquid pump 37. The right end of the mixing tank 35 is connected to the output end of the clean water pump 38. The number of nozzles 32 is multiple, and they are evenly arranged at the bottom of the annular spray pipe 31 with the same interval. Spray holes 33 are evenly provided at the bottom of the nozzles 32.
[0021] Confirm that the mixing tank 1 is stably placed on the support frame 2, the control valve 14 on the discharge pipe 13 is in the closed state, the cleaning liquid pump 37, the clean water pump 38 and the filter screen 36 of the automatic cleaning mechanism are not blocked or damaged, and the heating wire 52 and the temperature sensor 53 of the temperature control mechanism are properly wired.
[0022] The basic materials to be mixed are added into the mixing tank 1 through the feed hopper 21 at the top of the support frame 2. At the same time, the external colorant conveying pipe is connected to the feed pipe 12, and the colorant conveying system is started so that the colorant passes through the feed pipe 12, passes through the top plate 11 and enters the mixing tank 1 to complete the material proportioning.
[0023] When the temperature control mechanism is activated, the heating wire 52 in the heating chamber 51 is energized and heats up. The heat is transferred to the material inside the mixing tank 1 through the side wall. The temperature sensor 53 monitors the temperature of the material inside the mixing tank 1 in real time. When the temperature reaches the process requirements, the power of the heating wire 52 is automatically adjusted to maintain the material temperature stability, such as preventing the colorant from condensing due to low temperature and the material properties from being damaged by high temperature.
[0024] When the stirring mechanism is started, the motor 41 at the middle of the top plate 11 outputs power, which drives the rotating shaft 42 to rotate through the coupling. Multiple stirring plates 43 on the outer side of the rotating shaft 42 perform radial stirring of the material. At the same time, the reinforcing plate 44 at the bottom of the rotating shaft 42 drives the stirring base plate 45 to rotate. Because the front view section of the stirring base plate 45 is arc-shaped and the arc is consistent with and closely connected to the inner arc of the bottom of the stirring tank 1, it can scrape and stir the residual material at the bottom of the stirring tank 1 to avoid material sedimentation.
[0025] Once the materials are mixed evenly, open the control valve 14 at the middle end of the discharge pipe 13. The mixed materials are then discharged through the discharge pipe 13, completing the production process. After the discharge is finished, close the control valve 14.
[0026] The automatic cleaning mechanism is started, and the clean water pump 38 and the cleaning liquid pump 37 are turned on at the same time. The clean water and the cleaning liquid enter the mixing tank 35 to mix. The mixed cleaning liquid is transported to the annular spray pipe 31 through the connecting water pipe 34. Along the way, impurities are filtered by the filter screen 36 to prevent the nozzles from clogging. The multiple nozzles 32 evenly arranged at the bottom of the annular spray pipe 31 spray the cleaning liquid onto the inner wall of the mixing tank 1, the mixing plate 43, the mixing bottom plate 45 and other components through the spray holes 33 to achieve all-round automatic cleaning. After cleaning is completed, the pump body is turned off and the control valve 14 is opened to discharge the cleaning wastewater.
