AI Technical Summary

Technical Problem

When the existing material conveying mechanism transports materials, due to the height difference in the material transfer point, the material falls into the feed frame and causes impact, resulting in a large amount of suspended dust, which spreads to the working environment, causing serious dust pollution and endangering the health of the staff.

Method used

A dust-repressing material conveying mechanism for injection molding machines is designed. Through the combination of feed frame, port, dual-axis motor and fan blades, the inside of the collection box is in a negative pressure state. Dust enters the collection box through the port, and air is filtered through the filter to prevent the dust from diffusing. At the same time, by combining the fixed seat, rotating rod, buffer plate and torsion spring, the material is buffered to reduce impact force and block dust.

Benefits of technology

It effectively prevents dust from spreading from the opening at the top of the feed frame to the working environment, prevents serious dust pollution in the working environment, protects staff's health, and improves the practicality of the material conveying mechanism.

[0030] Through the coordinated use of the feed frame 2, the through port 4, the dual-axis motor 7 and the fan blades 8, the interior of the collecting box 3 is in a negative pressure state, so that the dust generated during the material transportation process enters the collecting box 3 through the through port 4, effectively preventing the dust from diffusing from the opening at the top of the feed frame 2 to the working environment, preventing serious dust pollution in the working environment, and ensuring the health of the staff.

[0031] The outside of the feed pipe 1 is fixedly connected to a discharge pipe 9 , and the conveying assembly includes a conveying shaft 10 rotatably connected to one side of the inner wall of the feed pipe 1 , and the discharge pipe 9 is located below the feed pipe 1 .

[0032] A conveying dragon 11 is arranged outside the conveying shaft 10 and inside the conveying pipe 1 , and one end of the conveying shaft 10 is fixedly connected to a pulley 12 which penetrates the outside of the conveying pipe 1 and is sleeved thereon.

[0033] An outlet 13 is provided at the bottom of the inner wall of the mounting frame 5, and a pulley 2 14 is provided on the other output end of the dual-axis motor 7. The positions of the pulley 12, the pulley 2 14 and the outlet 13 correspond to each other, and the diameter of the outlet 13 is larger than the diameter of the pulley 1 12, the pulley 2 14, and the pulley 1 12 and the pulley 2 14 are connected by belt transmission.

[0034] Two fixing seats 15 are fixedly connected to both sides of the inner wall of the feed frame 2, and two rotating rods 16 are fixedly connected to the outside of the fixing seats 15. The outsides of the two rotating rods 16 are rotatably connected to buffer plates 17. The outsides of the two rotating rods 16 are sleeved with torsion springs 18, which are installed between the fixing seats 15 and the opposite side of the buffer plates 17. The buffer plates 17 are used to buffer the granular materials. The buffer plates 17 are all inclined angle structures, and the buffer plates 17 on both sides of the inner wall of the feed frame 2 are cross-type;

[0035] Through the coordinated use of the fixed seat 15, the rotating rod 16, the buffer plate 17 and the torsion spring 18, the material entering the feed frame 2 can be continuously buffered, reducing the impact force generated by the material falling into the feed frame 2, avoiding the raising of a large amount of dust, and the setting of the buffer plate 17 can effectively block the dust, further avoiding the phenomenon of dust spreading from the opening at the top of the feed frame 2 to the working environment, thereby improving the practicability of the feeding mechanism.

[0036] Working principle: When the feeding mechanism is needed, first feed the material into the feeding pipe 1 through the feeding frame 2. The material will fall downward rapidly under the action of gravity. During the falling process, the material will continuously contact and impact the buffer plate 17. At this time, every two torsion springs 18 will buffer the corresponding buffer plate 17, so that the buffer plate 17 that is overturned by the impact will rotate and reset. After the material is buffered by the buffer plate 17 and the torsion spring 18, it finally enters the feeding pipe 1. Dust will be generated after the material falls downward and touches the bottom. The dust can be blocked by the setting of the buffer plate 17.

[0037] At the same time, the motor is started to drive the two conveying shafts 10 to rotate, and one of the output shafts drives the fan blades 8 to rotate. The rotation of the fan blades 8 sucks the gas inside the collection box 3 outward, so that the inside of the collection box 3 is in a negative pressure state, and the dust generated during the material transportation process enters the collection box 3 through the opening 4, and through the filter screen 6 fixedly connected to the installation frame 5, the gas discharged outward from the collection box 3 can be filtered to prevent the dust in the collection box 3 from being discharged from the installation frame 5, and the other output shaft drives the pulley 2 14 and drives the pulley 1 12 and the conveying shaft 10 to rotate synchronously through the belt, thereby driving the conveying dragon 11 to rotate, and the raw materials in the feed pipe 1 are transported from right to left, and then discharged through the discharge pipe 9.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
