Description

Technical Field

[0001] The utility model relates to the field of conveying equipment, in particular to a round rod-shaped raw material cutting production line. Background Art

[0002] At present, during the processing of quartz glass rods, the raw material rods need to go through the feeding, cutting and discharging processes. When feeding, manual feeding is mostly used to carry the raw material rods one by one to the cutting machine for cutting. The manual loading of workers has a high labor intensity, and loading takes up a lot of time in the project, making the overall project efficiency low. There is a lack of a conveying device that automatically transports the raw materials to the cutting station. In the cutting process, the traditional processing method is manual cutting. Workers use cutting machines for cutting. However, since the cutting machine does not have good safety protection measures, it is easy for workers to be in danger during the cutting process, which poses a safety hazard. In addition, the cutting surface of manual cutting is uneven, the cutting speed is slow, and the production efficiency is low. There is a lack of a device for automatically cutting the raw material rods. The cut raw material rods need to be output through a conveying device. The existing conveying devices mostly use a funnel to receive the material and then output it through a conveyor. A lot of raw material powder will be generated during the cutting process. The powder will generate dust during the falling process to pollute the factory environment. There is a lack of a conveying device that can reduce dust and has a fast discharging speed.

[0050] The discharge conveyor 53 is a belt conveyor; a pair of side baffles are symmetrically arranged on the frame of the discharge conveyor 53; a telescopic hose is arranged at the discharge port of the dust collecting funnel 52, and the telescopic hose is inserted into the feed port of the dust collecting bag 55.

[0051] Embodiment 1: The raw material bar is input through the feed end of the feed conveyor 1, and enters between the fixed baffle 4 and the adjustable baffle 5. During feeding, it is guided by the arc-shaped feed guide plate 12, so that the feeding of the raw material bar is smoother. When the feed conveyor 1 delivers the raw material bar to the discharge end, one end of the raw material bar abuts against the first end baffle 7, and the piston rod of the push rod cylinder 2 extends, and the raw material bar is pushed into the discharge chute 3 through the L-shaped push plate 6. The raw material bar is transported downward along the discharge chute 3 to the cutting station. When it is necessary to adjust the spacing between the fixed baffle 4 and the adjustable baffle 5, grasp the nut of the locking screw, turn the locking screw, release the lock, and move the adjusting rod 11 forward and backward along the adjusting hole in the middle of the positioning block 10 to adjust the spacing. After the adjustment is completed, the adjusting rod 11 is pressed and fixed from above by the locking screw. When the material is stuck, the piston rod of the lifting cylinder 13 is retracted, driving the first end baffle 7 to lift up, and the raw material rod can be quickly discharged along the discharge end of the feed conveyor 1. After the material blockage is removed, the lifting cylinder 13 is reset. The L-shaped push plate 6 can prevent the subsequent raw material rods from moving forward when the push cylinder 2 pushes the material, so that the feeding can be carried out in an orderly manner.

[0052] The raw material rods conveyed by the feed conveyor fall into the round rod conveying trough. When the raw material rods fall, they are blocked by the side blocking plate 32 to prevent them from falling. The piston rod of the feeding cylinder 22 extends out and pushes the raw material rod above the discharge port 25 through the pushing block 27. One end of the raw material rod is against the second end baffle 29. The upper pressure cylinder 23 drives the upper pressure block 28 to move downward to press the raw material rod from above to complete the positioning of the raw material rod. The transverse slide 33 drives the cutting machine 24 to move horizontally to cut the raw material rod. The cut raw material rods fall into the discharge port 25. The transverse slide 33 and the upper pressure cylinder 23 are reset. The feeding cylinder 22 drives the remaining raw material rods to press against the second end baffle 29. The above cutting process is repeated to continuously cut the raw material rods until the entire raw material rod is cut. The feeding cylinder 22 is reset and the next raw material rod is conveyed by the feeding conveyor for cutting. Since the cross section of the round bar conveying groove on the conveying platform 26 is V-shaped, it can adapt to raw material bars of different thicknesses, and the pusher block 27 is a quadrangular prism to match the round bar conveying groove. By adjusting the position of the adjustment rod 30 on the U-shaped adjustment frame 31, the distance between the second end baffle 29 and the end surface of the conveying platform 26 can be increased or decreased to adjust the length of the cut raw material bar.

[0053] The cutting machine is located above the discharge hopper 51. The cut round rod-shaped raw materials fall into the discharge hopper 51. The round rod-shaped raw materials are caught by the filter 54. Then the round rod-shaped raw materials slide down along the inclined filter 54 to the discharge conveyor 53 for output. When the round rod-shaped raw materials fall, the dust generated by cutting also falls together, falls into the dust collecting hopper 52 along the pores of the filter 54, and is concentrated and output to the dust collecting bag 55. When the round rod-shaped raw materials fall onto the discharge conveyor 53, fine dust is extracted through the dust extraction pipe 58, and most of the dust is blocked from overflowing through the door curtain 59, which significantly reduces the dust at the feed port of the discharge conveyor 53. A group of filter support rods 56 support the filter 54, so that the service life of the filter 54 is longer.
