Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a mixer for plastic processing. Background Technology

[0002] In the plastics processing industry, mixers are key equipment. When adding raw materials to mixers, manual operation is mostly relied upon. Workers need to frequently pour different types of raw materials into the mixer manually. However, due to the weight of the raw materials and the height of the mixer's feed port, the labor intensity and operation time of the workers are increased, affecting the efficiency of raw material mixing. At the same time, the direct pouring method is prone to spillage of raw materials and makes it inconvenient for workers to control the proportion of added raw materials. Whether the proportion of different raw materials is reasonable plays a crucial role in the performance of processed plastics. If the proportion is not properly controlled, it will directly affect the quality of the final product, which may lead to unstable product performance or even unqualified products, increase production costs and production cycle, and reduce the comfort of using the mixer. Utility Model Content

[0004] This utility model also provides a plastic processing mixer, comprising: a base plate; a mixing tank and a stirring mechanism are fixedly connected to the left end of the upper surface of the base plate; a feeding channel is fixedly connected to the upper surface of the mixing tank; a mounting base is rotatably connected to the right end of the upper surface of the base plate; a hydraulic lifting mechanism is fixedly connected to the upper surface of the mounting base; a mounting block is fixedly connected to the output end of the hydraulic lifting mechanism; a placement frame is provided on the right surface of the mounting block; a partition and a baffle are provided inside the placement frame; the partition is fixedly connected to the placement frame; torsion springs are fixedly connected between the baffle and the placement frame, and between the placement frame and the mounting block; an electromagnet and a magnetic suction plate are fixedly connected to the upper surface of the mounting block and the left surface of the placement frame, respectively; the right surface of the electromagnet is in contact with the left surface of the magnetic suction plate. This reduces the difficulty of adding raw materials from a height and improves the convenience of controlling the proportion of raw materials added.

[0005] According to the present invention, a mixer for plastic processing has an infeed channel without an upper wall, and the right half of the infeed channel is inclined downwards to the left. The height of the rear wall of the right half of the infeed channel is less than the height of the front wall. This improves the effectiveness of the infeed channel.

[0006] According to the present invention, a plastic processing mixer has a pad fixedly connected to the upper surface of the base plate, and the upper surface of the pad contacts the lower surface of the placement frame. This improves the stability of the placement frame in supporting raw materials.

[0007] According to the present invention, a plastic processing mixer has a rubber sheet fixedly connected to the left surface of the baffle, and the end of the rubber sheet away from the baffle is fixedly connected to the lower inner wall of the placement frame. This improves the flatness of the baffle after it is flipped over.

[0008] According to the present invention, a mixer for plastic processing has a battery fixedly connected to the upper surface of the output end of the hydraulic lifting mechanism, and a power line is provided between the battery and the electromagnet. This prevents the effect of the electromagnet from being affected.

[0009] According to the present invention, a mixer for plastic processing has an opening on the surface of the mounting block, and the power cable between the battery and the electromagnet is located inside the opening. This improves the convenience of pulling the power cable.

[0010] According to the present invention, in a plastic processing mixer, the electromagnet is embedded in the upper surface of a mounting block, and the right surface of the electromagnet protrudes from the right surface of the mounting block. This improves the stability of the electromagnet.

[0011] According to the present invention, a mixer for plastic processing has a mixing mechanism located below a mixing tank, with the mixing end of the mixing mechanism located inside the mixing tank. This design facilitates the maintenance of the mixing mechanism.

[0012] Beneficial effects:

[0013] The plastic processing mixer in this technical solution uses a mounting base, hydraulic lifting mechanism, and feeding channel to conveniently transfer plastic granules to a high position through a lifting and rotating structure, improving the convenience of adding plastic granules. The mounting block, electromagnet, magnetic plate, placement frame, torsion spring, partition, and baffle use magnetic attraction to fix the temporary storage part of the plastic granules, and the temporary storage part of the plastic granules is automatically flipped by contact with the magnetic attraction, improving the convenience of adding plastic granules. The baffle and partition connected to the placement frame by the torsion spring are used to separate the plastic granules to be added, improving the convenience for the operator to judge the total amount of different types of plastic granules to be added.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model discloses a plastic processing mixer, which includes: a base plate 1, a mixing tank 2 and a stirring mechanism 16 fixedly connected to the left end of the upper surface of the base plate 1, the stirring mechanism 16 being located below the mixing tank 2, the stirring end of the stirring mechanism 16 being located inside the mixing tank 2, a feeding channel 3 fixedly connected to the upper surface of the mixing tank 2, the stirring mechanism 16 being a common stirring device consisting of a servo motor and a stirring rod, used to stir the plastic particles inside the mixing tank 2, the feeding channel 3 having no upper wall, and the right half of the feeding channel 3 being inclined to the lower left, the height of the rear wall of the right half of the feeding channel 3 being less than the height of the front wall, the feeding channel 3 being used to accurately transfer the raw materials to be added into the interior of the mixing tank 2.

[0023] Specifically, when adding plastic granules, the raw material is directly added to the inside of the placement frame 7. After the placement frame 7 is raised and rotated to move above the feeding channel 3, since the feeding channel 3 lacks an upper wall, the placement frame 7 can smoothly tilt downwards. At this time, the raw material is poured into the inside of the feeding channel 3. The raw material enters the inside of the mixing tank 2 through the feeding channel 3. After the servo motor is turned on, it drives the stirring rod to rotate, thereby mixing the plastic granules that have entered the mixing tank 2.

[0024] A mounting base 4 is rotatably connected to the right end of the upper surface of the base plate 1. The mounting base 4 provides conditions for the rotation of the hydraulic lifting mechanism 5. The hydraulic lifting mechanism 5 is fixedly connected to the upper surface of the mounting base 4. The hydraulic lifting mechanism 5 is a common hydraulic lifting mechanism used to change the height of the placement frame 7. A mounting block 15 is fixedly connected to the output end of the hydraulic lifting mechanism 5. The right surface of the mounting block 15 is provided with a placement frame 7, which is used to temporarily store the plastic granules to be added. A pad block 17 is fixedly connected to the upper surface of the base plate 1. The upper surface of the pad block 17 contacts the lower surface of the placement frame 7. The pad block 17 is used to increase the height of the placement frame. To ensure stability, the placement frame 7 is equipped with a partition 10 and a baffle 11. The partition 10 is fixedly connected to the placement frame 7, and the baffle 11 cooperates with the partition 10 to separate the plastic particles to be added. Torsion springs 13 are fixedly connected between the baffle 11 and the placement frame 7, and between the placement frame 7 and the mounting block 15. The torsion springs 13 provide the baffle 11 and the placement frame 7 with automatic reset conditions. A rubber sheet 12 is fixedly connected to the left surface of the baffle 11. The end of the rubber sheet 12 away from the baffle 11 is fixedly connected to the lower inner wall of the placement frame 7. The rubber sheet 12 is used to cover the gap generated after the baffle 11 is flipped.

[0025] Specifically, when adding plastic granules, the placement frame 7 is lowered directly to contact the pad 17. At this time, the plastic granules are poured directly into the interior of the placement frame 7. The stress on the vertical baffle 11 is less than the elastic stress of the torsion spring 13, so the baffle 11 will not tilt. When the placement frame 7 is moved above the feeding channel 3 and tilted to the lower left, the plastic granules roll to the lower left. At this time, the pressure exerted by the plastic granules on the baffle 11 is greater than the elastic stress of the torsion spring 13, so the baffle 11 also tilts to the lower left. After the baffle 11 tilts, the rubber sheet 12 is stretched, blocking the gap between the baffle 11 and the placement frame 7, thereby preventing the plastic granules from getting stuck in the gap when the baffle 11 is reset. During the plastic pouring process, after the plastic granules inside are poured out, the baffle 11 is directly driven to reset by the torsion spring 13, thereby preventing the baffle 11 inside from affecting the pouring effect of the plastic granules.

[0026] Electromagnets 8 and magnetic plates 9 are fixedly connected to the upper surface of mounting block 15 and the left surface of placement frame 7. The right surface of electromagnet 8 is in contact with the left surface of magnetic plate 9. Electromagnet 8 is embedded in the upper surface of mounting block 15, and the right surface of electromagnet 8 protrudes from the right surface of mounting block 15. Electromagnet 8 and magnetic plate 9 cooperate to limit the range of motion of placement frame 7. Battery 6 is fixedly connected to the upper surface of the output end of hydraulic lifting mechanism 5. A power line is provided between battery 6 and electromagnet 8. An opening 14 is provided on the surface of mounting block 15. The power line between battery 6 and electromagnet 8 is located inside the opening 14. Battery 6 provides power to electromagnet 8.

[0027] Specifically, the magnetic attraction between the electromagnet 8 and the magnetic plate 9 keeps the placement frame 7 stable, thus preventing the placement frame 7 from tipping over during the rising process. After the hydraulic lifting mechanism 5 lifts the placement frame 7, the hydraulic lifting mechanism 5 is manually rotated backward, so that the placement frame 7 collides with the front wall of the feeding channel 3. At this time, the electromagnet 8 is turned off. Without the restraint of the electromagnet 8, the placement frame 7 tilts to the lower left under the influence of gravity, thus transferring the raw materials into the interior of the mixing tank 2.

[0028] Working principle: After the raw materials are poured into the placement frame 7, the hydraulic lifting mechanism 5 and the mounting base 4 move the placement frame 7 into the inside of the feeding channel 3. Then, the electromagnet 8 restricts the placement frame 7, causing it to tilt to the lower left, thus pouring the plastic granules inside the placement frame 7 into the mixing tank 2. The stirring mechanism 16 then mixes the plastic granules. However, due to the presence of the torsion spring 13, the raw materials inside the placement frame 7 cannot be completely poured out. Therefore, when adding different types of raw materials, it is necessary to manually collect any remaining raw materials. The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model.
