Description

Technical Field

[0001] The present application relates to the technical field of material transportation, and in particular to a high-efficiency bagged powder elevator. Background Art

[0002] During the product processing, powdered raw materials need to be transported from a low place to a high place. At present, when completing the above work, the powder or granular material in a flexible bag is generally poured into a container, and then the material is lifted by a hoist. In this way, when the powder is poured out of the flexible bag, smoke and dust will be generated, affecting the surrounding working environment; or the existing elevator transports the powder to a high place by moving the hopper, which will also be affected by the external environment and have a poor user experience.

[0003] A Chinese utility model with authorization publication number CN212558440U discloses a flexible lifting machine, which includes a frame, a lifting mechanism arranged on the frame, a suction nozzle arranged on the lifting mechanism, a suction fan connected to the suction nozzle and a feeding pipe connected to the air outlet port of the suction fan. The powder contained in the flexible bag is sucked by the suction nozzle and transported to a high place, thereby reducing smoke and dust formed by the collision of the powder; the lifting mechanism can lower the horizontal height of the suction nozzle so that the suction nozzle continues to be located in the powder pile until the powder is completely sucked; after the powder in the flexible bag is completely extracted, the staff is reminded to add or replace the powder bag in time, thereby facilitating the suction of the bagged powder.

[0004] The flexible elevator has the following shortcomings: after a bag of raw materials is lifted, a worker or a robot arm needs to remove the bag before hanging another bag. During this process, the flexible elevator is in a stopped state, which takes a lot of time and makes the flexible elevator less efficient. Utility Model Content

[0005] In order to improve the working efficiency of the flexible elevator, the present application provides a high-efficiency bagged powder elevator.

[0006] This application provides a high-efficiency bagged powder elevator, which adopts the following technical solution:

[0007] A high-efficiency bagged powder lifting machine comprises a mounting frame, a suction mechanism arranged on the mounting frame and used to suck out and lift the dust in the flexible bag in the suction area, and a feeding mechanism arranged on the mounting frame and used to drive the flexible bag to move, wherein the feeding mechanism comprises:

[0008] The first slider is vertically slidably arranged on the mounting frame;

[0009] A first driving member, which is disposed on the mounting frame and is used to drive the first sliding block to slide;

[0010] A hanging rack, the hanging rack is rotatably arranged on the first sliding block, and the hanging rack is provided with a plurality of hanging components for hanging the flexible bag;

[0011] A rotating member is arranged on the first sliding block and is used to drive the hanger to rotate. The rotating member is used to move the hanging components to the suction area in sequence and lift the flexible bag in the suction area.

[0012] By adopting the above technical solution, the powder in the flexible bag is sucked and lifted by the suction mechanism, and at the same time, the worker hangs the flexible bag on the fixed hook in the non-suction area. When a bag of powder is lifted, the rotating part drives the hanger to rotate, so that a new flexible bag is transferred to the suction area and the powder is sucked through the suction nozzle, thereby shortening the time for replacing the flexible bag and improving the working efficiency of the flexible lifting machine.

[0013] Furthermore, the rotating member is composed of a fixed plate and a rotating cylinder, wherein the fixed plate is arranged on the first slider, and the rotating cylinder is arranged on the fixed plate and is used to drive the hanger to rotate and facilitate workers to lift the flexible bag on the lifting assembly in the non-suction area.

[0014] By adopting the above technical solution, the fixed plate makes the rotating cylinder away from the first driving member, so as to facilitate the rotation of the hanging rack. After a bag of powder is lifted, the rotating member drives the hanging rack to rotate, so that a new flexible bag is transferred to the suction area and the powder is sucked through the suction nozzle, so as to shorten the time of replacing the flexible bag.

[0015] Further, the hanging assembly comprises:

[0016] A fixing ring, wherein the fixing ring is arranged on the hanging bracket;

[0017] A plurality of fixing hooks are arranged at intervals on the fixing ring and are used to hang the top of the flexible bag.

[0018] By adopting the above technical solution, multiple groups of fixed hooks open the flexible bag and hang it on the fixed ring, and the suction mechanism extends into the flexible bag through the fixed ring to suck and lift the powder in the flexible bag between the multiple groups of fixed hooks.

[0019] Furthermore, the mounting frame is provided with a supporting assembly for supporting the bottom of the flexible bag, and the supporting assembly includes:

[0020] A support seat, which is slidably disposed on the mounting frame in a direction close to or away from the plurality of suspension components and supports the bottom of the flexible bag;

[0021] A gas pressure rod, which is arranged on the mounting frame and is used to drive the support seat to slide;

[0022] The regulating switch is arranged on the supporting seat and is used to control the connection or closing of the upper and lower chambers of the gas pressure rod.

[0023] By adopting the above technical solution, when the adjustment switch is turned on, the upper and lower chambers of the gas pressure rod are connected, thereby facilitating the adjustment of the height of the support seat; when the adjustment switch is turned off, the upper and lower chambers of the gas pressure rod are closed, so that the height of the support seat is fixed.

[0024] Furthermore, a receiving plate is rotatably provided on the support seat to abut against the bottom of the flexible bag, the rotation axis of the receiving plate coincides with the rotation axis of the hanging bracket, and the hanging bracket drives the receiving plate to rotate through the suspended flexible bag.

[0025] By adopting the above technical solution, the receiving tray rotates along with the hanging rack, so that the receiving tray always supports the bottom of the flexible bag, thereby reducing the probability of damage to the flexible bag.

[0026] Furthermore, a plurality of hemispherical grooves are provided on the receiving plate, and the hemispherical grooves correspond to the hanging components and abut against and fix the bottom of the flexible bag.

[0027] By adopting the above technical solution, the hemispherical groove abuts and fixes the bottom of the flexible bag, which makes it easy for the flexible bag to drive the receiving plate to rotate. At the same time, the hemispherical groove makes the powder in the flexible bag more concentrated, which is convenient for sucking and lifting the powder.

[0028] Further, the material suction mechanism comprises:

[0029] a second slider, the second slider being slidably disposed on the mounting frame in a direction approaching or moving away from the flexible bag;

[0030] A second driving member, the second driving member is disposed on the mounting frame and is used to drive the second slider to slide;

[0031] A suction nozzle, which is arranged on the second sliding block and is used to extend into the flexible bag;

[0032] A suction fan, which is arranged on the second sliding block and is connected to the suction nozzle, and is used to generate suction force so that the suction nozzle can suck out the powder in the flexible bag;

[0033] A feeding pipe is arranged on the second sliding block and is used to discharge the powder discharged by the suction fan into a designated position.

[0034] By adopting the above technical solution, the second driving member causes the second slider to move downward and extend the suction nozzle into the flexible bag, and the powder is sucked by the suction fan and sent to the designated position through the feeding pipe, so as to facilitate the suction and lifting of the powder in the flexible bag.

[0035] Furthermore, the suction nozzle is composed of a flexible hose, a hard tube and a pull rope. The flexible hose is arranged on the suction fan, and the hard tube is arranged on the end of the flexible hose away from the suction fan. Two groups of pull ropes are slidably arranged on the second slider and are located on opposite sides of the flexible hose and connected to the hard tube. The two groups of pull ropes are used to adjust the extension and retraction amount of the flexible hose.

[0036] By adopting the above technical solution, the flexible hose allows the hard tube to extend into the powder pile, reducing the probability of damage to the hard tube or the hard tube damaging the flexible bag. At the same time, by adjusting the length of the two sets of draw ropes, it is easy to adjust the extension and contraction amount of the flexible hose, thereby adjusting the angle of the hard tube.

[0037] In summary, the present application includes at least one of the following beneficial technical effects:

[0038] The suction nozzle is driven by the second driving member to extend into the flexible bag in the suction area, and the suction fan sucks and lifts the powder in the flexible bag. At the same time, the worker hangs the flexible bag on the fixed hook in the non-suction area. When a bag of powder is lifted, the rotating member drives the hanger to rotate, so that a new flexible bag is transferred to the suction area and the powder is sucked through the suction nozzle, thereby shortening the time for replacing the flexible bag and improving the working efficiency of the flexible lifting machine.
