Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, and in particular relates to a powder additive unloading device. Background Art

[0002] ASA high-glue powder is an additive composed of acrylonitrile, styrene, and acrylic rubber. It is an impact-modified resin with excellent weather resistance, mechanical properties, and high temperature resistance. It is widely used in the automotive, electronic and electrical, and construction fields. After the production of ASA high-glue powder is completed, it needs to be unloaded into aggregate barrels and sold in aggregate barrels.

DETAILED DESCRIPTION

[0020] In order to better understand the purpose, structure and function of the present invention, the present invention is described clearly and completely below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 3 A powder additive unloading device shown in the figure includes: a lower hopper 1, a conveyor line 2, a lifting plate 3 and a lifting mechanism. The lower hopper 1 is wide at the top and narrow at the bottom and is funnel-shaped. Its upper part is connected to the production box 16, and a control valve 13 is provided at the lower part for controlling the unloading process of the lower hopper 1. The conveyor line 2 is provided below the lower hopper 1. A plurality of aggregate barrels 4 with openings facing upwards are passed through and detachably connected in the middle of the conveyor line 2.

[0023] The conveyor belt drives the aggregate barrel 4 to transport. When the aggregate barrel 4 is above the lifting plate 3, the conveyor belt stops moving; the lifting mechanism drives the lifting plate 3 to rise and fit the bottom of the aggregate barrel 4, and then continues to rise until the aggregate barrel 4 is separated from the conveyor line 2, until the top of the aggregate barrel 4 is located at the bottom of the lower hopper 1; the rear control valve 13 is opened, the lower bin is unloaded, and the gravity sensor measures the weight of the aggregate box; after the measured weight reaches the preset weight, the control valve 13 is closed, the lifting mechanism drives the lifting plate 3 and the aggregate barrel 4 to fall, the aggregate barrel 4 is connected to the conveyor line 2 through the hook 7, the lifting plate 3 returns to the initial position, and the conveyor line 2 continues to move; until the next aggregate barrel 4 moves to the top of the lifting plate 3, repeat this process to complete the unloading process; the filled aggregate barrel 4 can be removed by loosening the clamp 5. This process has a high degree of automation, and the gravity sensor detects the quality of the powder in the aggregate barrel 4. There is no need for manual handling and the increase or decrease of the powder in the aggregate barrel 4, which saves manpower. Specifically, programming can be performed according to the speed of the conveyor line 2, the material discharge speed, the height between the lifting plate 3 and the lower hopper 1, and the signal detected by the gravity sensor to control the start and stop time of the lifting mechanism, the start and stop time of the conveyor belt, and the opening and closing of the control valve 13 to achieve the above process; of course, monitoring can also be carried out with the aid of sensors, for example, a laser sensor is arranged on the upper part of the lifting plate 3 to detect whether the aggregate barrel 4 is located above the lifting plate 3; a laser sensor is arranged on the lower part of the side wall of the lower hopper 1 to detect the inner wall of the aggregate barrel 4 to determine whether the aggregate barrel 4 is located at the bottom of the lower hopper 1; the implementation means are conventional technical means adopted by electromechanical personnel, which will not be described in detail here.
