Description

Technical Field

[0001] The present invention relates to the technical field of powder conveying, and more specifically, to an anti-detachment structure for a powder conveying bag dropping device. Background Art

[0002] In today's technical field, a vane discharge valve is widely used as a discharge and bag dropping device for powder materials. The specific operation method is to sleeved a material bag at the outlet position of the vane discharge valve, and the inlet end of the vane discharge valve is connected to the powder feed port. By precisely controlling the flipping of the vanes inside the vane discharge valve, the bag dropping process of the powder material can be effectively realized, so as to achieve the purpose of preventing powder caking. The design of this device takes into account the fluidity of the material, ensuring the smooth and efficient discharge process. The vane discharge valve has a simple structure, is easy to maintain, and has a long service life, so it has been widely used in industrial production.

[0003] According to the patent document: CN102717904A, a fully automated and environmentally friendly packaging device that can integrate five processes including unmanned bag insertion, packaging, bag dropping, bag cleaning, and bag straightening is disclosed. It is composed of six systems including a discharge system, a packaging system, a metering system, a dust cleaning and collecting system, a packaging bag conveying system, and a microcomputer control system. The above five systems can be concentrated in the packaging device housing. The feed end of the discharge system is connected to the material bin, and the discharge end of the discharge system is connected to the packaging system. The metering system and the dust cleaning and collecting system are located below the packaging system, and the packaging bag conveying system is located at the bottom of the packaging device. The above five systems are centrally controlled by the microcomputer control system to complete each step of packaging. The present invention can fully realize unmanned operation, and the entire packaging process is in a closed space, greatly reducing dust emissions.

[0004] During the conveying process of powder materials, the commonly adopted method is to place the bag body on the bottom tray, with the bag mouth opened and wrapped around the feeding port, so that the powder can smoothly enter the bag body. However, although this setting supports the bag body with the tray, when the bag body starts to be filled with powder, due to the gradual accumulation of the powder, its weight will continuously increase. As the weight increases, relative sliding is likely to occur between the bottom of the bag body and the tray. Especially when the powder conveying speed is fast or the powder fluidity is good, this sliding phenomenon will become more significant. This unstable relative movement between the bag body and the tray may cause the bag body to shift and even fall off in extreme cases. Such a situation not only affects the accuracy of the packaging process but also reduces the efficiency of the packaging operation. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-falling structure for a powder conveying and bagging device. The technical problem to be solved by the present invention is: although the bag body is supported by a tray, when the powder is conveyed inside the bag body, due to the gradual increase in the weight of the accumulated powder, the bottom of the bag body is often prone to relative sliding with the tray, especially when the powder conveying speed is fast or the powder fluidity is good, this sliding phenomenon is more obvious, which may cause the bag body to deviate or even fall off, affecting the accuracy and efficiency of packaging.

The inner wall of the push-pull plate 310 is slidably connected to the top of the outer wall of the discharge tube body 31, and the front and rear sides of the bottom of the push-pull plate 310 are fixedly connected with push-pull vertical rods 311. The bottoms of the two push-pull vertical rods 311 extend to the bottom of the connecting plate 32 through the two through grooves 35 opened in the connecting plate 32. The inner bottom of the two push-pull vertical rods 311 is fixedly connected with an inverted L-shaped connecting rod 312, and the inner walls of the two inverted L-shaped connecting rods 312 are fixedly connected with sleeves 313. The inner wall of the sleeve 313 is slidably connected to the outer wall of one side of the discharge tube body 31 on the inner side of the connecting plate 32 and the bottom clamping plate 36. The bottoms of the two inverted L-shaped connecting rods 312 are fixedly connected with an extrusion outer plate 314, and the bottom of the outer wall of the sleeve 313 is fixedly connected with a top pressure plate 315. Each component 4 includes two expansion rods 41, and the outer walls of the left and right groups of expansion rods 41 are slidably connected to the left and right sides of the inner sides of the two guide rods 34 respectively. The outer sides of the left and right groups of expansion rods 41 are fixedly connected with hinge blocks 42, and the sides of the left and right groups of hinge blocks 42 away from the expansion rods 41 are rotatably connected with rotating rods 43.

The middle parts of the inner sides of the two rotating plates 46 are rotatably connected with bidirectional hinge rods 48. The sides of the left and right groups of third hinge blocks 47 away from the rotating plates 46 are rotatably connected to the outer walls of the left and right groups of transfer blocks 37.On the sides of the outer wall of the sleeve 313 away from the rotating plate 46, both sides of two bidirectional hinged rods 48 are rotatably connected. At the bottoms of the two rotating plates 46, clamping plate connecting plates 49 are fixedly connected respectively. At the bottoms of the two clamping plate connecting plates 49, semi-circular clamping plates 410 are fixedly connected.

[0031] During the operation of conveying powder into the bag, first, the bag mouth of the bag needs to be inserted through the inner sides of the extrusion outer disc 314 and the pressing disc 315, and ensure that the bag mouth is turned flat and laid on the top of the extrusion outer disc 314. Subsequently, start the pneumatic control box 14. The pneumatic control box 14 pumps gas into and out of the pneumatic push rod 38 through the air pipe 17. Under the action of the gas, the pneumatic push rod 38 will pull the push and pull block 39 downward, thereby driving the push and pull disc 310 and the push and pull vertical rod 311 to move downward synchronously. During this process, the inverted L-shaped connecting rod 312 will also move downward. At the same time, the sleeve 313 slides downward on the outer wall of the main material pipe 31 until the pressing disc 315 and the bag mouth sleeved by the extrusion outer disc 314 abut against the top of the bottom clamping disc 36, thus fixing the bag mouth between the bottom clamping disc 36 and the extrusion outer disc 314. At this time, the bottom of the bag is placed on the inner wall of the support plate 19, ensuring that the bag will not shift or fall off during the process of conveying and dropping the bag, improving the accuracy and efficiency of conveying. While fixing the bag, the sleeve 313 moves downward, and then drives the two rotating plates 46 to rotate through the two bidirectional hinged rods 48. During the rotation of the two rotating plates 46, the left and right groups of expansion and contraction rods 41 respectively slide outward along the inner sides of the two guide rods 34. At this time, the two semi-circular clamping plates 410 move inward until the two semi-circular clamping plates 410 tightly clamp and fix the part sleeved on the outer wall of the main material pipe 31. In this way, further fixation of the connection between the main material pipe 31 and the bag mouth is achieved, preventing loosening or falling off between the main material pipe 31 and the bag mouth during the process of conveying powder, and further improving the stability and reliability of conveying. In addition, this design can not only effectively clamp the bag mouth, but also effectively prevent dust from easily rising between the outlet of the blade discharge valve and the bag mouth of the material bag during powder discharging, and the powder is easily lifted by the air flow, resulting in a poor surrounding environment and being easily inhaled by the staff into the body, causing health impacts.

[0032] In addition, the staff can easily move the entire trolley 1 to any designated position at the work site by operating the push handle 12. Such a design enables the device to adapt to various complex and changeable working environments, significantly improving the flexibility and application range of the device. During this process, the bucket connected to the bucket connection plate 16 is filled with the powder material to be transported. By precisely controlling the air control box 14, the operator can finely adjust the telescopic movement of the pneumatic push rod 38, thereby accurately controlling the tightness between the main body 31 of the feeding pipe and the bag mouth. Such a design ensures that the powder can smoothly and stably flow into the bag body, thus improving the efficiency and reliability of the entire transportation process. While transporting the powder, the support plate 19 on the support connection plate 18 continuously provides stable support for the bottom of the bag body, effectively preventing shaking or tilting caused by the weight of the bag body or the flow of the powder. In addition, the two semi-circular clamping plates 410 tightly clamp the connection between the main body 31 of the feeding pipe and the bag mouth, effectively preventing powder leakage during transportation, ensuring a clean working environment and the health and safety of the staff. The anti-detachment structure of the entire device is designed reasonably and efficiently, and is very easy to operate, thus greatly improving the efficiency and stability of powder transportation and bag dropping, making the entire work process smoother and safer.

[0033] Working principle of the present invention: When it is necessary to transport powder into the bag body, first pass the bag mouth of the bag body through the inside of the extrusion outer disc 314 and the top pressure disc 315, and turn the bag mouth over and lay it flat on the top of the extrusion outer disc 314. Then start the air control box 14. The air control box 14 pumps gas into and out of the pneumatic push rod 38 through the air pipe 17. The pneumatic push rod 38 is pulled downward by the gas to drive the push-pull block 39, and then drives the push-pull disc 310 and the push-pull vertical rod 311 to move downward synchronously. At this time, the inverted L-shaped connecting rod 312 moves downward accordingly, and at the same time, the sleeve 313 slides downward on the outer wall of the main body 31 of the feeding pipe until the top pressure disc 315 and the bag mouth sleeved with the extrusion outer disc 314 abut against the top of the bottom clamping disc 36, thereby fixing the bag mouth between the bottom clamping disc 36 and the extrusion outer disc 314. At this time, the bottom of the bag body is placed on the inner wall of the support plate 19. While fixing the bag body, the sleeve 313 moves downward and then drives two rotating plates 46 to rotate by pulling two double-direction articulated rods 48. During the rotation of the two rotating plates 46, the left and right groups of expansion and contraction rods 41 respectively slide outward along the inner sides of the two guide rods 34. At this time, the two semi-circular clamping plates 410 move inward until the two semi-circular clamping plates 410 tightly clamp and fix the part sleeved on the outer wall of the main body 31 of the feeding pipe, thus realizing further fixation of the connection between the main body 31 of the feeding pipe and the bag mouth.
