Abstract
Description
Technical Field
[0001] The present invention relates to an automatic material suction structure for ton bags and its working method. Background Art
[0002] In plastic production, it is often necessary to send the raw materials in ton bags to production equipment. Since the fully loaded ton bags are heavy, if the raw materials are poured out after being lifted by a lifting device, the requirements for the equipment are high, and the operation difficulty and danger are high. If a material suction device is used for suction, since the ton bag is formed by a flexible bag, the inside of the ton bag is likely to be folded during suction, affecting the suction and resulting in incomplete suction. Summary of the Invention
[0003] The present invention provides an automatic material suction structure for ton bags, including a bracket, a material suction device, and a lifting device. The lifting device is provided with a driving mechanism and a lifting ring. A flexible connecting rope is arranged between the driving mechanism and the lifting ring. The driving mechanism drives the lifting ring to move up and down. The material suction device is connected to a weight reduction device and can approach or leave the ton bag. Its working method is as follows:
[0004] S1. The driving mechanism drives the lifting ring to descend to a height where the ton bag can be hooked, and the ton bag is installed on the lifting ring and stabilized.
[0005] S2. The driving mechanism drives the lifting ring to rise and makes the lifting ring tighten the ton bag, and at this time the ton bag does not rise.
[0006] S3. By means of weight reduction of the weight reduction device, the material suction device descends into the ton bag, and the material suction device starts to suck materials.
[0007] S4. As the suction progresses, the weight of the ton bag will gradually decrease until the weight of the ton bag is less than the driving force of the driving mechanism, and the ton bag is lifted. As the ton bag is lifted, the material suction device gradually extends into the bottom of the ton bag and sucks the materials at the bottom of the ton bag empty.
[0008] In one or more embodiments, the weight reduction device is provided with a plurality of weights, and the plurality of weights can be reduced one by one or simultaneously.
[0009] In one or more embodiments, a steel cable is arranged between the weight reduction device and the material suction device, and a steel wire hose is arranged on the material suction device to connect to a negative pressure mechanism.
[0010] In one or more embodiments, a first idler wheel is arranged between the weight reduction device and the material suction device, and the steel cable is hung on the first idler wheel.
[0011] In one or more embodiments, the driving mechanism is a driving cylinder.
[0012] In one or more embodiments, the driving cylinder is provided with a lifting stroke, and the lifting stroke is equal to or slightly greater than the depth of the ton bag.
[0013] In one or more embodiments, in S2, when the sling ring tightens the ton bag, the moving path distance of the sling ring is less than the lifting stroke of the driving mechanism.
[0014] In one or more embodiments, a steel cable is arranged between the driving mechanism and the sling ring, and the steel cable is hung on the second idler wheel.
[0015] In one or more embodiments, an induction switch is further provided, and after the induction switch senses that the driving mechanism resets, it drives the alarm device to alarm and the material suction ends.
[0016] Advantages of the present invention: After the sling ring is lowered to the ton bag by the driving mechanism, the driving mechanism lifts the sling ring to tighten the ton bag and lowers the material suction device into the ton bag for material suction. As the material suction device sucks the material, the weight inside the ton bag decreases. With the driving force of the driving mechanism remaining unchanged, the ton bag is lifted, causing the material suction device to continuously extend into the ton bag and suck all the raw materials inside the ton bag. The concept is ingenious, the structure is simple, the requirements for the strength and power of the equipment are low, production is easy, operation is simple, and the risk is low.
