Description

Technical Field

[0001] This utility model relates to the field of plastic sheet production, and in particular to a raw material batching device for plastic sheet production. Background Technology

[0002] Plastic sheets are widely used in construction, packaging, electronics and other fields due to their excellent properties such as light weight, corrosion resistance and easy processing. The production of plastic sheets usually requires mixing various types of plastic granules, such as polyethylene, polypropylene and polyvinyl chloride, in a precise formula ratio. Only by ensuring the accuracy and uniformity of the ingredients can the final plastic sheets have stable and standard physical and chemical properties, such as strength, toughness and heat resistance.

[0003] Plastic granules have strong hygroscopic properties. In humid environments, they easily absorb moisture from the air, causing them to stick together and gradually form clumps of varying sizes. However, current mixing equipment cannot properly crush and pre-treat the injected plastic granules. When these clumps enter the mixing equipment, they cannot be evenly mixed with other normal granules, resulting in uneven performance of the plastic sheets during production and affecting product quality. Therefore, we propose a raw material batching device for plastic sheet production to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device, with its feeding hopper and feeding pipe, can guide agglomerated particles into the crushing hood. Simultaneously, a variable frequency motor drives the high-speed rotation of the crushing rod and crushing toothed plate, which impacts and crushes the agglomerated particles. The crushed particles are then screened by a mesh screen and fall into the batching bin, ensuring uniform particle size for subsequent processes. A geared motor drives the rotation of the stirring rod, causing the first and second stirring blades to agitate and mix the plastic particles from multiple directions. This device ensures that the crushed agglomerated particles are thoroughly and evenly mixed with other normal particles, guaranteeing consistent physicochemical properties across the plastic sheet and improving product quality.

Each crushing tooth plate 8 is located above the mesh screen plate 9. A batching and mixing component 4 is provided on one side of the batching box 1. The high-speed rotation of the crushing rod 7 and the crushing tooth plates 8 driven by the variable frequency motor 6 can crush and squeeze agglomerated particles. The crushed particles can fall into the batching box 1 after being screened by the mesh screen plate 9, ensuring that the particle size is uniform when entering the subsequent process.

[0025] In a further embodiment, the mixing component 4 includes a geared motor 401 fixedly mounted on one side of the mixing tank 1. A stirring rod 402 is fixedly mounted on the output end of the geared motor 401. Multiple first stirring blades 403 and multiple second stirring blades 404 are fixedly connected to the outer surface of the stirring rod 402. Both the first stirring blades 403 and the second stirring blades 404 are located inside the mixing tank 1. Two first bearings 405 are fixedly embedded in the inner wall of the mixing tank 1. The inner rings of the two first bearings 405 are connected to both ends of the stirring rod 402. The outer surface is fixedly connected, and the inner top wall of the crushing cover 3 is fixedly embedded with the second bearing 17. The outer surface of the top of the crushing rod 7 is fixedly connected to the inner ring of the second bearing 17.

The setting of the first bearing 405 can ensure the smooth rotation of the stirring rod 402, and the setting of the second bearing 17 can ensure the stable rotation of the crushing rod 7.

[0026] In a further embodiment, the inner bottom wall of the batching box 1 has two discharge holes 12, the bottom ends of which are fixedly connected to discharge pipes 10. The outer surfaces of the two discharge pipes 10 are fixedly connected to electric valves 11, which are electric shut-off ball valves. Two sets of support seats 14 are fixedly connected to the outer surface of the batching box 1. Two guide plates 13 are fixedly connected to the side of the two sets of support seats 14 that are close to each other. The two guide plates 13 are located below the two discharge pipes 10.

The setting of the support base 14 and the guide plate 13 can help guide the material to be discharged and collected smoothly. The transparent observation plate 18 makes it convenient for operators to observe the material in the box. The controller 5 can control the operation of the entire device.

[0027] The working principle of this utility model is as follows: When it is necessary to feed plastic sheet raw materials, plastic particles need to be poured into the crushing hood 3 through the feeding hopper 16 and the feeding pipe 15, and the variable frequency motor 6 is started to drive the crushing rod 7 to rotate. Then, the multiple crushing tooth plates 8 on the surface of the crushing rod 7 rotate at high speed, which can hit and squeeze the agglomerated plastic particles and crush them into smaller particles. The crushed particles fall into the feeding box 1 below through the mesh screen plate 9.

[0028] After the agglomerated plastic granules are crushed and enter the batching box 1, the geared motor 401 is started to drive the stirring rod 402 to rotate. Then, the first stirring blade 403 and the second stirring blade 404 on the surface of the stirring rod 402 stir the plastic granules in the batching box 1. The first stirring blade 403 and the second stirring blade 404 are distributed in position, which can turn and mix the plastic granules from multiple directions. When the plastic granules are evenly mixed, the controller 5 controls the electric valve 11 to open, so that the mixed plastic granules can be discharged through the discharge pipe 10.
