Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, the uniform feeding device for the high-density polyethylene sheath material comprises a feeding motor 1, a feeding screw 4 is arranged on an output shaft of the feeding motor 1, the feeding screw 4 is arranged in a feeding pipe 3, a blending mechanism connected with the feeding pipe 3 is arranged above the feeding motor 1, and the blending mechanism comprises a uniform feeding unit and a mixing unit 7.

The feeding motor 1 works to drive the feeding screw rod 4 to rotate, so that the materials in the connecting pipe 9 are uniformly conveyed to a subsequent device.

The uniform feeding unit comprises a blending motor 5 arranged above the feeding motor 1, a blending screw 8 is arranged on an output shaft of the blending motor 5, the blending screw 8 is arranged in a blending pipe 6, a connecting pipe 9 is arranged at one end of the blending pipe 6 opposite to the blending motor 5, and the connecting pipe 9 is communicated with the blending pipe 6 and the feeding pipe 3.

The blending motor 5 is operated to rotate the blending screw 8 so that the material in the homogenizing tank 71 is uniformly transported to the connecting pipe 9.

And frequency conversion boxes 2 are arranged between the blending motor 5 and the blending screw 8 and between the feeding motor 1 and the feeding screw 4. The frequency conversion box 2 is mainly used for adjusting the feeding speed of materials.

A rubber buffer cushion is arranged between the blending motor 5 and the feeding motor 1. The rubber buffer cushion can weaken the influence of the vibration of the blending motor 5 and the feeding motor 1 on the mixing unit 7 and avoid the unevenness of the materials in the homogenizing tank 71.

The connecting pipe 9 is arranged obliquely. The included angle between the connecting pipe 9 and the feeding pipe 3 is 30-45 degrees. The connecting pipe 9 arranged at 30-45 degrees does not influence the normal falling of the materials, and prevents the granular materials from falling too much along the gaps of other materials, thereby ensuring the uniformity of the raw materials.

As shown in FIG. 2, the mixing unit 7 comprises a homogenizing tank 71 communicated with the blending pipe 6, a cover plate 73 is arranged at the top of the homogenizing tank 71, a feed inlet and a homogenizing motor 74 are arranged on the cover plate 73, and a stirring blade 75 is arranged on an output shaft of the homogenizing motor 74. The bottom of the homogenizing tank 71 is provided with a material level indicator 72. The stirring blade 75 is provided with a through hole 76.

The working principle of the uniform feeding device for the high-density polyethylene sheath material is as follows: the material level device 72 detects the materials in the homogenizing tank 71 to ensure that the homogenizing tank 71 is not short of materials and is not rich of materials, and the homogenizing motor 74 drives the stirring blades 75 to rotate, so that the materials in the homogenizing tank 71 are mixed, and the uniformity of the materials is kept; the blending motor 5 works to enable the blending screw 8 to rotate, so that the materials in the homogenizing tank 71 are uniformly conveyed to the connecting pipe 9; the feeding motor 1 works to drive the feeding screw rod 4 to rotate, so that the materials in the connecting pipe 9 are uniformly conveyed to a subsequent device.

This an even feeding device for high density polyethylene sheath material's advantage and beneficial effect lie in:

1. through the matching of the blending unit and the connecting pipe 9, the raw materials of the semi-finished product enter the feeding screw 4 in a uniformly blended state, and the product quality is improved.

2. The mixing unit 7 can keep the materials uniform in the homogenizing tank 71, and the problem that the materials are uneven due to the fact that the granular materials fall to the bottom of the homogenizing tank 71 along the gap is avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
