Description

Technical Field

[0001] The present application relates to the field of PVC pipe processing, and in particular to an automatic material discharge device. Background Art

[0002] At present, when PVC pipes are processed, the feeding end usually uses a crane to lift the whole bag of powder onto the unloading rack, and then uses a negative pressure suction device to transport it through a pipeline to the machine head for melting and forming.

[0003] When loading, each bag of powder weighs thousands of pounds. However, the current unloading rack usually includes a unloading rack body and a funnel-shaped unloading bin opened on the unloading rack body. After the powder bag is hoisted onto the unloading rack, the opening of the powder bag faces downward, allowing the powder to fall under the action of its own gravity. However, it is found during use that the powder bag has a slow unloading speed when the amount of powder is large or small, and workers need to manually sort it out. The reason is that when the amount of powder is large, the gravity of the upper powder is completely pressed on the discharge port of the powder bag, causing blockage. When the amount of powder is small, the upper gravity is insufficient, but the lower powder bag accumulates in the unloading bin after unloading, blocking the subsequent unloading of powder.

[0004] In view of this, those skilled in the art need to improve the existing material unloading rack to overcome the above-mentioned defects. Utility Model Content

[0005] The main purpose of the present application is to provide an automatic material discharge device, which does not require manual combing during the discharge process and will not cause blockage.

[0006] In order to achieve the above-mentioned objectives, in the first aspect, the present application provides an automatic unloading device, comprising a unloading rack, a funnel-shaped unloading bin arranged in the unloading rack, a unloading port arranged at the bottom of the unloading bin, the unloading port is connected with a vacuum suction pipe, a cover plate is arranged on the top of the unloading rack, a through hole is opened on the cover plate, the size of the through hole is smaller than the upper opening size of the unloading bin, and an elastic support member is arranged between the cover plate and the unloading rack.

[0007] A further improvement is that the cover plate is rectangular, and there are four elastic support members, which are arranged at four corners of the cover plate.

[0008] A further improvement is that the elastic support members include a guide column vertically fixed on the upper end surface of the material discharging rack, a guide hole opened on the cover plate for the guide column to pass through, an elastic member sleeved on the guide column, and a limiting member is also provided on the upper end of the guide column.

[0009] A further improvement is that the cross section of the limiting member is circular, and its diameter is larger than the diameter of the guide hole.

[0010] A further improvement is that the lower end of the guide column is welded and fixed to the material placing rack.

[0011] A further improvement is that the elastic member is a spring.

[0012] A further improvement is that a support blocking member is also provided in the discharge bin to prevent the bag opening of the packaging bag from entering the discharge opening.

[0013] A further improvement is that the supporting and blocking member comprises a plurality of equidistantly arranged supporting rods, and both ends of the supporting rods are respectively welded and fixed to two sides of the unloading bin.

[0014] The utility model provides an automatic unloading device, which has the beneficial effect compared with the prior art, that is, by arranging elastic support members and cover plates, when the powder bag is hoisted onto the unloading rack, most of the weight of the powder bag is pressed on the cover plate, so that when the amount of powder is large, it will not cause blockage at the discharge port of the powder bag, and when the amount of powder is small after unloading, the gravity on the elastic support members is reduced, and the cover plate is lifted upward under the elastic force of the elastic support members, so that the powder bag after unloading can be straightened to a certain extent, and will not be entangled in the unloading bin, thereby avoiding the subsequent powder falling. The above-mentioned unloading rack only needs to be hoisted to the unloading rack by a crane, and the powder bag can be manually opened and placed in the unloading rack, without the need for manual combing during the unloading process, which greatly reduces the labor intensity.
