Description

Technical Field

[0001] The invention relates to the technical field of parts processing, in particular to a multifunctional material guiding device for parts processing. Background Art

[0002] The stamping shop's riveting process for water-jacketed threaded plugs and aluminum washers previously relied on manual loading (the material frame was a plastic frame, but the load inside was heavy). Because the workpieces were heavy, workers had to lift and pour them into the material box on a vibrating plate. This was laborious and posed safety risks and the risk of product collisions.

[0003] In the packaging workshop, products were previously hoisted directly into the material bucket (which was a large and heavy iron frame) and poured onto one end of the inspection and packaging table. This was extremely inefficient, time-consuming, and labor-intensive, and there were certain risks if the operation was not careful.

[0004] To sum up the above two problems, there is the inconvenience of loading raw materials and the inconvenience of unloading materials before product packaging. Summary of the Invention

[0013] As a further solution of the present invention: the length of some of the loading boxes is smaller than the width of the conveyor belt, and compared with the center-centered design of the conveyor belt, the length of some limiting slides is consistent with the groove length of the corresponding limiting slide groove, and both are smaller than the length of the loading box.

[0014] As a further solution of the present invention: the material unloading mechanism includes two fixed seats, both of which are vertically fixedly installed on the top of the machine base, and the two ends of the rotating roller are rotatably installed with the corresponding fixed seats respectively.

[0015] As a further solution of the present invention: four limit grooves are provided on the upper side surface of the arc-shaped material discharge ramp, and the four limit grooves are symmetrically arranged on both sides of the width direction of the arc-shaped material discharge ramp.

[0018] Beneficial effects of the present invention:

[0019] First, based on the actual feeding height, we independently designed and manufactured an automatic feeding machine, which greatly reduced the labor intensity of employees and improved the feeding reliability. The effects or benefits produced are: effectively reduced the labor intensity of workers in feeding. This automatic feeding machine can realize the automatic recovery of the plastic frame after unloading, as well as the rapid replacement of the plastic frame. The most critical thing is that an adjustment motor is installed on the side panel of the frame. The adjustment motor drives the corresponding active roller to rotate, and then drives the synchronous roller to rotate through the support rod. The synchronous roller itself is a lining sleeve on the inner ring wall of the conveyor belt. Therefore, the conveying angle of the top of the conveyor belt can be adjusted while the conveyor belt is running normally, thereby realizing the adjustment of the feeding height, which is more convenient to use.

The arc-shaped material discharge ramp and the top of the arc-shaped material discharge ramp are provided with two bottom clamps that are arranged opposite to each other and can adjust the spacing relatively. Silicone pads are installed on the opposite sides of the two bottom clamps. In the process of clamping the discharge barrel by the bottom clamps, the silicone pads can buffer the deformation, increase the clamping area, and change the clamping shape. It has a good clamping effect on square or round discharge barrels, and what is more important is that the spacing adjustment between the two bottom clamps on the arc-shaped material discharge ramp in the present invention is automatic, and it only needs to be driven by the rotating roller to rotate clockwise, thereby driving the arc-shaped material discharge barrel to rotate clockwise. The material discharge ramp rotates upward and to the right synchronously, and after the discharge barrel clamped by the two bottom splints is lifted, the material inside is poured out to the right along the arc-shaped material discharge ramp. After the material discharge is completed, the rotating roller rotates counterclockwise, thereby driving the arc-shaped material discharge ramp to rotate downward and to the left synchronously until the arc-shaped material discharge ramp conflicts with the top of the machine base, thereby prompting the square base to slide in the square groove, and then pulling the corresponding tension spring to be forced to stretch, and finally achieving an increased spacing between the two bottom splints, making it convenient to place the square or round material discharge barrel on the top of the arc-shaped material discharge ramp, and after the arc-shaped material discharge ramp rotates, the square or round material discharge barrel is automatically clamped and fixed, which is convenient and quick to use.

An adjusting motor 22 is fixedly installed on the outer wall of one of the machine frame side plates 2, and a driving roller 28 is rotatably installed between the two machine frame side plates 2. The output end of the adjusting motor 22 extends between the two machine frame side plates 2 and is fixedly connected to the driving roller 28. The outer roller wall of the driving roller 28 is vertically fixedly connected to a support rod 29. Synchronous rollers 25 are rotatably installed on the opposite sides of the two machine frame side plates 2. The ends of the support rods 29 are rotatably installed with the two synchronous rollers 25. The synchronous rollers 25 can rotate with the rotation of the driving rollers 28, and the conveyor The outer ring wall of the belt 26 is installed with several feeding mechanisms 3, and the several feeding mechanisms 3 all include mounting seats 33. Several mounting seats 33 are vertically fixedly installed on the outer ring wall of the conveyor belt 26 at equal intervals. Several mounting seats 33 are detachably installed with feeding boxes 31 on the side away from the conveyor belt 26. The specifications of the feeding boxes 31 are consistent. During the transportation and feeding process, it can always ensure that the opening is facing upward to avoid leakage of raw materials. The top of the machine base 1 is also vertically fixedly installed with a pouring mechanism 4, which includes a rotating roller 42. The outer roller wall of the rotating roller 42 is fixedly installed with an arc-shaped pouring ramp 5. Two bottom splints 51 are slidably provided on the arc-shaped pouring ramp 5. The two bottom splints 51 are installed on the opposite sides of the two bottom splints 51. Silicone pads are installed, and the silicone pads have a good clamping, limiting and fixing effect on square or round discharge barrels.

[0037] like Figure 2-3 As shown, it is particularly special that a driving motor 21 is fixedly installed on the outer side wall of one of the frame side plates 2, and an active roller 24 is rotatably installed between the two frame side plates 2. The output end of the driving motor 21 extends through and extends between the two frame side plates 2 and is fixedly connected to the active roller 24. A limiting cylinder 23 is rotatably installed on the opposite side of the two frame side plates 2, and a plurality of driven rollers 27 are rotatably installed between the two frame side plates 2. The plurality of limiting cylinders 23, the two synchronous rollers 25 and the plurality of driven rollers 27 are connected by a conveyor belt 26. The driven rollers 27 and the plurality of limiting cylinders 23 are all located in the middle of the transmission path of the conveyor belt 26, which play a role in adjusting the surrounding operation path of the conveyor belt 26.

[0038] like Figure 1-7The cam 32 is fixedly mounted on the side of the loading box 31 close to the corresponding mounting seat 33, and the cam 32 is slidably mounted on the corresponding cam 34. The cam 32 has handles 35 fixedly mounted on both ends of the loading box 31 for easy disassembly and replacement. The length of the loading box 31 is less than the width of the conveyor belt 26, and compared with the central design of the conveyor belt 26, it will not touch the limiting cylinders 23. The length of the limiting slides 32 is consistent with the groove length of the corresponding limiting slide 34, and is less than the length of the loading box 31, so that the loading box 31 can only be disassembled from one side, which improves the safety of the transportation process while retaining the convenience of disassembly.

[0039] like Figure 4 As shown, what is particularly special is that the unloading mechanism 4 includes two fixed seats 41, both of which are vertically fixedly installed on the top of the machine base 1, and the two ends of the rotating roller 42 are rotatably installed with the corresponding fixed seats 41. A rotating motor 43 is fixedly installed on the outer wall of one of the fixed seats 41. The output end of the rotating motor 43 passes through the corresponding fixed seat 41 and is fixedly connected to the rotating roller 42. The rotating roller 42 is designed to be away from the conveyor belt 26, so that the arc-shaped unloading ramp 5 has sufficient rotation and lifting space;

[0040] like Figure 5-7As shown, what is particularly special is that four limiting grooves (52) are provided on the upper side of the arc-shaped material discharge ramp (5), and the four limiting grooves (52) are symmetrically arranged on both sides of the width direction of the arc-shaped material discharge ramp (5). The four limiting grooves (52) are all adapted to slide and install limiting members (53). The upper end of the limiting member (53) extends out of the limiting groove (52) and is fixedly connected to the bottom clamping plate (51). Tension springs (53) are installed between the limiting members (53) and the inner groove wall of the corresponding limiting groove (52). 54), through the elastic restoring force provided by the tension spring 54, the corresponding limit member 53 is pulled closer to the corresponding bottom clamping plate 51, and a square groove 55 is provided on the lower side of the arc-shaped material discharge ramp 5. A square base 56 is installed in the square groove 55 for lifting and sliding. A limit frame 561 is fixedly installed on the top of the square base 56. The limit frame 561 is set in the arc-shaped material discharge ramp 5 so that the square base 56 will not fall from the square groove 55. Two lifting columns 57 are vertically fixed on the top of the square base 56. The two opposite outer walls of each lifting column 57 are connected with a pull rope 58. Four guide wheels 59 are rotatably installed in the arc-shaped material discharge ramp 5. The four guide wheels 59 are respectively set at the ends of the corresponding limit grooves 52. The ends of the four pull ropes 58 pass around the corresponding guide wheels 59 and finally penetrate into the corresponding limit grooves 52 and are fixedly connected to the corresponding limit members 53. The rising square base 56 will push the lifting column 57, and then pull the pull rope 58 to overcome the elastic restoring force of the tension spring 54, so that the two bottom clamps 51 The spacing is temporarily increased to facilitate the placement of the discharge barrel between the two bottom clamps 51. Two arc-shaped baffles 510 are fixedly installed on the arc-shaped material discharge ramp 5 to prevent the product from falling from the arc-shaped material discharge ramp 5, thereby improving the safety of product transportation. The two arc-shaped baffles 510 are both arranged on both sides of the arc-shaped material discharge ramp 5. A mounting groove 511 is provided at the top of the arc-shaped material discharge ramp 5. A number of rotating rollers 512 are rotatably installed between the two opposite inner groove walls of the mounting groove 511. The number of rotating rollers 512 are collectively surrounded by a transmission belt 513.

[0041] Working principle of the present invention:

[0042] In the first step, the driving motor 21 is started, which in turn drives the active roller 24 to rotate. Through the cooperation of the two synchronous rollers 25, the active roller 24 and the conveyor belt 26 are in rolling contact, which can drive the conveyor belt 26 to rotate in a circular motion. During the circular motion of the conveyor belt 26, the limiting cylinders 23 and the driven rollers 27 adjust the path of the conveyor belt 26. Finally, the conveyor belt 26 rotates in a circular motion along the contour of the frame side plate 2.

[0043] In the second step, several loading boxes 31 are slidably inserted into corresponding mounting seats 33 through the relative cooperation of limiting slide bars 32 and corresponding limiting slide grooves 34. Since several mounting seats 33 are themselves vertically fixedly mounted on the outer ring wall of conveyor belt 26, the loading boxes 31 at the lower position and the raw materials in the loading boxes 31 can be lifted to a higher position together with the circular operation of conveyor belt 26, and rotated through the top end of conveyor belt 26. After the rotation, the opening of the loading box 31 faces downward and the raw materials are discharged downward. After the discharge is completed, the loading box 31 will fall back to the lower position along with the conveyor belt 26, which is convenient for the next loading or replacement.

[0044] In the third step, in order to meet the feeding requirements of different heights, the driving roller 28 can be driven to rotate by starting the adjustment motor 22, and then the two synchronous rollers 25 are driven to rotate through the support rod 29. The synchronous rollers 25 are always rolled in the inner ring of the conveyor belt 26. When the two synchronous rollers 25 are forced to rotate, the height of the end of the conveyor belt 26 also changes accordingly. The above adjustment process can be carried out synchronously with the normal feeding process, so it is easy to use.

[0045] In the fourth step, the rotating motor 43 is started again, thereby driving the rotating roller 42 to rotate, thereby driving the entire arc-shaped material discharge ramp 5 to rotate and descend in height until it conflicts with the top of the machine base 1. At this time, the square base 56 first conflicts with the machine base 1, and then the arc-shaped material discharge ramp 5 will continue to rotate and descend. At this time, the square base 56 and the two lifting columns 57 at the top will rise and slide relative to the arc-shaped material discharge ramp 5, and then they will respectively pull the corresponding limit members 53 through the corresponding guide wheels 59 through the pull ropes 58, thereby overcoming the pulling force of the corresponding tension springs 54, forcing the limit members 53 to slide in the corresponding limit grooves 52, and finally increasing the distance between the two bottom splints 51 arranged opposite to each other, making it convenient to place the square or round material discharge barrel between the two bottom splints 51 on the arc-shaped material discharge ramp 5;

[0046] In the fifth step, the rotating motor 43 is started again, which drives the rotating roller 42 to rotate in the opposite direction, thereby driving the entire arc-shaped material discharge ramp 5 to rotate and rise in height until it no longer conflicts with the top of the machine base 1. At this time, the square base 56 will no longer slide relative to the arc-shaped material discharge ramp 5, and will no longer continue to pull the corresponding pull rope 58. At this time, the four tension springs 54 respectively recover due to elasticity, and respectively pull the corresponding limit members 53, that is, the corresponding bottom splints 51 to move toward each other, and finally conflict with the outer wall of the discharge barrel, and because the bottom splints 51 Silicone pads are installed on both sides facing each other. Through the deformation of the silicone pads, the bottom splint 51 can have a good extrusion, limiting and fixing effect on both square and round discharge barrels. When the discharge barrel rotates with the arc-shaped discharge ramp 5 to open downward, the product will begin to be poured out. The product will interact with the surface of the arc-shaped discharge ramp 5 until it slides to the transmission belt 513. The static friction force generated by the gravity of the product and the surface of the transmission belt 513 prompts the transmission belt 513 to start a circular operation, and finally transports the product away from the arc-shaped discharge ramp 5.
