It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance and is widely used in medical, food and other industries.

[0003] In the production process of thermoplastic polyurethane elastomer film, the raw material particles need to be heat-melted, and a feeding device is required to evenly place the raw material particles. However, the existing feeding device cannot filter the raw material particles with larger volume, which leads to uneven heat melting or difficulty in heat melting, bringing adverse effects.

[0023] In order to achieve the purpose of stably supporting the housing 1, refer to Figure 2 The support component 2 includes a support seat 21. A guide groove 22 communicating with the outside is provided on the front of the outer surface of the support seat 21, which can realize the guiding effect when the auxiliary storage barrel 71 slides out from the bottom wall of the inner cavity of the shell 1. A plurality of support columns 23 are fixedly connected to the lower end of the outer surface of the support seat 21 in a circular array, and a lower pad 24 is fixedly connected to the lower ends of the plurality of support columns 23.

[0024] In order to achieve the purpose of more convenient feeding of raw materials, refer to Figure 2The feeding mechanism 3 includes a conical funnel 31, a collecting cover shell 32 is fixedly connected to the lower end of the outer surface of the conical funnel 31, and the lower part of the outer surface of the conical funnel 31 is fixedly connected to the upper end of the outer surface of the shell 1.

[0025] Under the action of the conical funnel 31, the raw material particles poured into the inner cavity of the conical funnel 31 can slowly slide into the inner cavity of the supporting shell 2 41 along the inner surface of the conical funnel 31, and a certain buffering force can prevent direct vertical falling from causing damage to the raw material particles.

[0026] In order to achieve the purpose of conveying raw materials of specified volume, refer to Figure 2 The feeding mechanism 4 includes a supporting shell 41, a feeding disc 42 is fixedly connected to the bottom wall of the inner cavity of the supporting shell 41, a plurality of feeding holes 43 communicating with the outside are arranged in a circular array on the upper end of the outer surface of the feeding disc 42, and the upper end of the outer surface of the supporting shell 41 is fixedly connected to the lower end of the outer surface of the collecting cover shell 32.

[0027] Particles of the raw materials falling into the inner cavity of the supporting shell 2 41 that meet the diameter size will directly continue to fall into the inner cavity of the storage barrel 71 through the plurality of feeding holes 1 43 .

[0028] In order to absorb the dust dropped during the raw material transportation process, refer to Figure 2 The dust collection mechanism 5 includes two exhaust pipes 51, and a fan 52 is fixedly connected to one side of the lower outer surface of the two exhaust pipes 51 close to each other. An air inlet pipe 53 is installed on the front of the outer surface of the fan 52, and the lower end of the outer surface of the fan 52 is fixedly connected to the middle part of the upper end of the outer surface of the lower pad 24.

[0029] When the raw material particles slide down from the inner cavity of the conical funnel 31 and scatter to the bottom wall of the inner cavity of the support shell 2 41, the dust carried on their outer surface will be scattered in the inner cavity of the support shell 2 41. At this time, the power of the fan 52 is turned on, so that the two exhaust pipes 51 can exhaust the inner cavity of the support shell 2 41, thereby extracting the dust in the inner cavity of the support shell 2 41.

[0030] In order to achieve the purpose of filtering larger raw material particles, refer to Figure 3 The filtering mechanism 6 includes a filter plate 61, and a plurality of filter holes 62 communicating with the outside are formed in a circular array on the bottom wall of the inner cavity of the filter plate 61, and the diameters of the plurality of filter holes 62 are the same as the diameters of the plurality of feed holes 43, and the lower end of the outer surface of the filter plate 61 is slidably connected to the upper end of the outer surface of the feed disc 42.

[0031] When there are particles with larger diameters in the raw materials scattered into the inner cavity of the supporting shell 41, they will be stuck on the upper part of the filter holes 62. At this time, the filter plate 61 can be taken out from the inner cavity of the chute 11 and dumped.

[0032] In order to store the raw materials in batches and facilitate the counting of quantities, refer to Figure 4 The storage mechanism 7 includes a material storage barrel 71, a material dividing plate 72 is fixedly connected to the bottom wall of the inner cavity of the material storage barrel 71, and the lower end of the outer surface of the material storage barrel 71 is slidably connected to the bottom wall of the inner cavity of the shell 1.

[0033] When raw material particles of specified sizes are scattered into the storage barrel 71 through a plurality of feed holes 43, they will be stored in batches in four inner cavities separated by the dividing plate 72, so as to make it easier to estimate the number of raw material particles collected and whether it has reached the number required for processing.

[0034] It should be noted that the specific installation method, circuit connection method and control method of the blower 52 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0035] The working principle of the utility model is as follows: first, raw material particles are thrown into the inner surface of the conical funnel 31, so that they are slowly scattered to the inner cavity of the supporting shell 41 along the inner surface of the conical funnel 31, and the particles of the raw materials falling into the inner cavity of the supporting shell 41 that meet the diameter size will directly continue to fall to the inner cavity of the storage barrel 71 through a plurality of feeding holes 43, and at the same time, the raw material particles sliding down from the inner cavity of the conical funnel 31 will carry dust on their outer surfaces during the scattering process, which will be scattered in the inner cavity of the supporting shell 41. At this time, the power of the fan 52 is turned on, so that the two exhaust pipes 51 can extract the dust from the inner cavity of the supporting shell 41, and the particles with larger diameters in the raw materials scattered into the inner cavity of the supporting shell 41 will be stuck on the upper part of a plurality of filter holes 62, at this time, the filter disc 61 can be taken out from the inner cavity of the chute 11 and dumped, during which the raw material particles that meet the specified size will be scattered to the storage barrel 71 through a plurality of feeding holes 43, and will be stored in batches in the four inner cavities isolated by the dividing plate 72.
