Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a raw material mixing equipment for plastic production and processing. Background Technology

[0002] Plastic raw materials are polymers, commonly known as plastics or resins. Plastic raw material mixing devices are common industrial equipment used to mix different types, colors, or shapes of plastic particles together to obtain the desired plastic raw material mixture. According to a search, Chinese patent publication number CN220373649U discloses a plastic raw material mixing device, which relates to the field of raw material mixing. It includes a processing box, a support frame fixedly connected to the outer wall of the processing box, a drying cylinder fixedly installed on the inner wall of the processing box, a conveying cylinder fixedly installed on the inner wall of the drying cylinder, an oil pump fixedly connected to the outer wall of the processing box, an oil inlet pipe fixedly connected to the oil inlet end of the oil pump, and the end of the oil inlet pipe away from the oil pump located inside the processing box.

[0003] While the above technical solution can dry the mixed plastic raw materials inside the drying cylinder simultaneously from the inside and outside, effectively improving the drying efficiency of the mixed plastic raw materials, the second stirring rod used for stirring the raw materials is fixed in position during use, which makes it impossible to stir the raw materials in different places, thus affecting the stirring effect. Furthermore, heating the raw materials from the inside by heating oil not only increases the cost of use, but also the heat is transferred gradually and cannot be heated quickly.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Example 1:

[0021] like Figures 1 to 4 As shown, a raw material mixing device for plastic production and processing includes a shell 1, an inner liner 2 for mixing plastic raw materials fixedly connected inside the shell 1, a top cover 3 fixedly connected to the top of the shell 1, and a stirring mechanism 4 installed on the top cover 3. The stirring mechanism 4 includes a first hollow tube 41 rotatably connected through the top cover 3. A hollow frame 42 and a turntable 43 are sequentially fixedly fitted on the outer surface of the first hollow tube 41. The interior of the hollow frame 42 is connected to the interior of the first hollow tube 41. Two second hollow tubes 44 are symmetrically rotatably connected through the hollow frame 42 and the turntable 43. The top end of the second hollow tube 44 is connected to the interior of the hollow frame 42. Spiral stirring blades 45 are fixedly connected to the outer surfaces of both the first hollow tube 41 and the second hollow tube 44. A motor 46 is fixedly installed on the top of the top cover 3. A first gear 47 is fixedly connected to the output shaft of the motor 46 and the top end of the first hollow tube 41. The two first gears 47 mesh with each other. An internal gear ring 48 is fixedly connected to the lower surface of the top cover 3, and a second gear 49 that meshes with the internal gear ring 48 is fixedly sleeved on the outer surface of the second hollow tube 44.

[0022] In use, the rotation of motor 46 drives the rotation of the first hollow tube 41 through two first gears 47. The rotation of the first hollow tube 41 drives the rotation of the hollow frame 42 and the turntable 43, which in turn drives the second hollow tube 44 to revolve, thus performing transverse stirring of the plastic raw material. While the second hollow tube 44 revolves, the cooperation of the second gear 49 and the internal gear ring 48 causes the second hollow tube rod 44 to rotate, thereby driving the corresponding spiral stirring blade 45 to rotate, which can lift and tumble the plastic raw material, thereby improving the mixing effect of the plastic raw material.

[0023] Example 2:

[0024] like Figures 1 to 3 As shown, a heating mechanism 5, which cooperates with the stirring mechanism 4, is installed on the top cover 3. The heating mechanism 5 includes a hot air blower 51 fixedly installed on one side of the top of the top cover 3. A connecting pipe 52 is fixedly connected to the air outlet end of the hot air blower 51. One end of the connecting pipe 52 is connected to the top end of the first hollow tube 41 through a rotary joint. Multiple air outlet holes 53 are sequentially opened on the outer surfaces of the first hollow tube 41 and the second hollow tube 44. A first through hole 54 communicating with the inside of the outer shell 1 is opened on one side of the top of the inner liner 2, and a second through hole 55 is opened on the bottom of the outer shell 1.

[0025] When mixing plastic raw materials, the hot air generated by the hot air blower 51 can be delivered to the first hollow tube 41 through the connecting pipe 52. Then, with the cooperation of the hollow frame 42, the hot air can be delivered to the second hollow tube 44 at the same time. Then, it is sprayed out through each air outlet 53, which can heat and dry the plastic raw materials from the inside, which can improve the heat transfer speed and thus improve the drying efficiency of the plastic raw materials. Excess hot air will flow into the gap between the outer shell 1 and the inner liner 2 through the first through hole 54. The outer shell 1 is made of heat insulation material, which can prevent heat loss. At this time, the excess heat can heat and insulate the inner liner 2, improving the energy utilization efficiency.

[0026] In this technical solution, a feed pipe 6 is fixedly connected to one side of the top of the inner liner 2, and a discharge pipe 7 is fixedly connected to the bottom of the inner liner 2. The feed pipe 6 and discharge pipe 7 facilitate the entry and exit of materials. Both the feed pipe 6 and discharge pipe 7 are equipped with control valves to facilitate the control of the material speed. A bracket 8 is fixedly connected to the bottom of the outer shell 1. A controller is installed on the bracket 8 to facilitate the control of the operation of the motor 46 and the hot air blower 51. The controller belongs to the prior art and is not described in detail.

[0027] Working principle: During use, the motor 46 rotates, which drives the first hollow tube 41 to rotate through the two first gears 47. The rotation of the first hollow tube 41 drives the hollow frame 42 and the turntable 43 to rotate, which in turn drives the second hollow tube 44 to revolve, thus horizontally stirring the plastic raw material. While the second hollow tube 44 revolves, the second hollow tube rod 44 rotates on its own axis with the cooperation of the second gear 49 and the internal gear ring 48, which drives the corresponding spiral stirring blade 45 to rotate, thereby lifting and turning the plastic raw material, thus improving the mixing effect of the plastic raw material.

[0028] When mixing plastic raw materials, the hot air generated by the hot air blower 51 can be delivered to the first hollow tube 41 through the connecting pipe 52. Then, with the cooperation of the hollow frame 42, the hot air can be delivered to the second hollow tube 44 at the same time. Then, it is sprayed out through each air outlet 53, which can heat and dry the plastic raw materials from the inside, which can improve the heat transfer speed and thus improve the drying efficiency of the plastic raw materials. Excess hot air will flow into the gap between the outer shell 1 and the inner liner 2 through the first through hole 54. The outer shell 1 is made of heat insulation material, which can prevent heat loss. At this time, the excess heat can heat and insulate the inner liner 2, improving the energy utilization efficiency.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
