Description

Technical Field

[0001] This invention relates to the field of material handling, specifically to a safe and automatic feeding mechanism for barrel-shaped chemical raw materials. Background Technology

[0002] Some chemical raw materials are loaded in plastic chemical drums. When adding chemical raw materials to the processing equipment in a chemical plant, the drums are lifted and poured into the feed inlet of the processing equipment.

[0003] A Chinese public document (CN117566457B) describes an automatic feeding mechanism for barrel-shaped chemical raw materials. By employing a structure of a first guide frame and a second guide frame, the mechanism guides and conveys the moving platform and the barrel, thereby lifting and conveying the barrel to the vicinity of the filling port at the top of the processing equipment. Combined with the guiding effect of the spiral part on the moving platform, the barrel is tilted to dump the raw materials, thus realizing an automatic feeding method for raw materials. This method is not only simple to operate, eliminating the need for manual pushing of the barrel to dump the raw materials, greatly simplifying the operation and improving work efficiency, but also effectively improving safety and reducing the difficulty of operation. In publicly available literature, the moving platform and the material bucket are moved upward by winding the plate chain. Then, the moving platform is guided by the first and second guide frames, and the material is poured out by the lifting mechanism that flips the moving platform and the material bucket. However, the lifting mechanism is connected to the moving platform and the material bucket by the plate chain. The plate chain is a flexible transmission component. In particular, when the moving platform and the material bucket are moved laterally by the plate chain, lateral errors of the plate chain cannot be avoided. Moreover, the moving platform and the material bucket filled with material are heavy. Frequent lateral displacement of the moving platform and the material bucket by the plate chain can easily cause the pin in the middle of the plate chain to loosen, affecting the actual service life of the plate chain. This results in a great safety hazard when the plate chain moves the material bucket. Summary of the Invention

The two ends of the arc-shaped through groove are at different distances from the center of the sleeve frame, that is, when the turntable rotates, it can push the column at the bottom of the positioning pin seat, thereby allowing multiple push rods to clamp the material barrel inside the sleeve frame.

[0011] Preferably, the limiting component includes a limiting cylinder fixedly mounted on the outer wall of the sleeve, and a sliding plate is slidably assembled inside the limiting cylinder. A pull rod and a positioning post are respectively fixedly arranged on the upper and lower end faces of the sliding plate, and the pull rod and the positioning post slide through the limiting cylinder.

The threaded rod is threadedly assembled with the sealing cylinder. The suction cup can be pressed against the surface of the material barrel, and then the piston disc can be pulled out to create negative pressure in the space between the suction cup and the material barrel, thereby performing negative pressure suction and positioning of the material barrel.

[0013] Preferably, the connection point between the through pipe and the sealing cylinder is located below the piston disc, so as to ensure that the piston disc can move upward and suck up the suction cup.

[0014] Preferably, the material pouring auxiliary unit includes an extended arc plate fixedly disposed on the outer wall of the sleeve frame, and the extended arc plate and the lever are oppositely distributed. An edge sealing plate is fixedly disposed between the two sides of the extended arc plate and the sleeve frame. The bottom of the extended arc plate is closed. An annular groove is formed on the outer wall of the sleeve frame, and the annular groove is located between the extended arc plate and the two edge sealing plates. A storage box is fixedly disposed at the bottom of the sleeve frame. A plurality of through holes are formed at the bottom of the annular groove, and the through holes communicate with the storage box. The extended arc plate and the two edge sealing plates form a closed frame, which covers the outer wall of the sleeve frame.

[0015] Preferably, the extended arc plate bends toward the side away from the center of the frame. When the frame tilts with the bucket, the extended arc plate can guide or collect the chemical raw materials that spill out when the bucket tilts into the closed frame.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-7 The diagram shows a barrel-shaped automatic chemical raw material safety feeding mechanism, including: a base plate 1, and two symmetrically distributed corner brackets 2 mounted on the upper end of the base plate 1. The corner brackets 2 are obtuse-angled, and their upper surfaces are parallel to the base plate 1. A first guide wheel 6 is mounted at the corner of the corner bracket 2, and a second guide wheel 7 is mounted at the end of the corner bracket 2 away from the base plate 1. A motor 4 is fixedly mounted on the upper surface of the base plate 1, and two winding wheels 5 are fixedly mounted on the outer surface of the output end of the motor 4. Each winding wheel 5 is located directly below the two corner brackets 2. A support plate 3 for carrying the barrel is also fixedly mounted on the upper surface of the base plate 1, and the support plate 3 is located between the two corner brackets 2. The motor 4 is a geared motor with high torque, which makes the winding and unwinding of the cable 11 more stable. It also includes: a feeding unit, which is used to lift the material bucket, and the feeding unit is located between the two corner brackets 2; The fixing unit is used to fix material buckets of different sizes inside the feeding unit. The fixing unit is located on the outside of the feeding unit. The material discharge auxiliary unit is used to prevent the raw materials in the bucket from spilling along the bucket wall. The material discharge auxiliary unit is located on one side of the feeding unit.

[0021] The feeding unit includes a sleeve frame 8 located between two corner brackets 2. Each corner bracket 2 has a hollow groove inside, and a polygonal sliding block 10 is installed inside the hollow groove. Two sides of the sliding block 10 slide against the upper and lower walls of the hollow groove. A cable 11 is fixedly bolted between the sliding block 10 on the same side and the winding wheel 5. The cable 11 is also wound around the surfaces of the second guide wheel 7 and the first guide wheel 6 respectively. A rotating shaft 9 is rotatably installed inside each sliding block 10, and the two sleeve frames are fixedly connected. A frame 8 is provided, and the inside of the frame 8 is used to place the material bucket. The horizontal part of the corner bracket 2 is also provided with a deflection component and an auxiliary retraction component. The sliding block 10 is pentagonal. As shown in the figure, the top edge of the sliding block 10 is, in clockwise order, the first horizontal edge, the first inclined edge, the second inclined edge, the second horizontal edge, and the third inclined edge. The distance between the first horizontal edge and the second horizontal edge is A, and the distance between the second inclined edge and the third inclined edge is B, and A=B. The width of the hollow slide groove is C, and C is 1-2mm larger than A and B.

[0022] The first inclined edge is fixed to the cable 11, and the cable 11 is kept in a state of pulling the sliding block 10 at an inclined upward.

[0023] The deflection component includes a rack 33 fixedly installed inside the hollow slide groove, and the rack 33 is fixed to the corner bracket 2. A gear 32 is also fixedly fitted on the outer surface of each rotating shaft 9, and the gear 32 is movably meshed with the rack 33. When the sliding block 10 moves to the point where the gear 32 meshes with the rack 33, the continuous movement of the sliding block 10 can cause the rotating shaft 9 to deflect with the sleeve 8.

[0024] The auxiliary retraction component includes a straight groove 29 formed inside the horizontal portion of the corner bracket 2, and the straight groove 29 communicates with the hollow slide groove. A push block 30 is slidably mounted inside the straight groove 29, and a second spring 34 is fixedly disposed between the end of the push block 30 near the second guide wheel 7 and the straight groove 29. A blocking block 31 is also fixedly disposed outside the push block 30, and the blocking block 31 extends into the interior of the hollow slide groove. When the sliding block 10 slides to the horizontal portion of the corner bracket 2, the push block 30 can be pushed by the blocking block 31, thereby compressing the second spring 34.

[0025] The fixing unit includes several push rods 12 that are radially slidably inserted into the sleeve frame 8. Each push rod 12 has a positioning pin seat 17 fixedly fitted on one end face away from the center of the sleeve frame 8. A third spring 40 is also movably fitted on the outer surface of each push rod 12. The two ends of the third spring 40 are fixed to the positioning pin seat 17 and the sleeve frame 8, respectively. A turntable 15 is rotatably fitted on the outer surface of the sleeve frame 8. Several arc-shaped through grooves 16 are opened inside the turntable 15. The column at the bottom of each positioning pin seat 17 is slidably embedded in the arc-shaped through groove 16. A lever 18 is also fixedly installed on the outer wall of the turntable 15. A limit component is also provided between the turntable 15 and the sleeve frame 8. The two ends of the arc-shaped through groove 16 are not at the same distance from the center of the sleeve frame 8. That is, when the turntable 15 rotates, it can push the column at the bottom of the positioning pin seat 17, thereby allowing the multiple push rods 12 to clamp the material barrel inside the sleeve frame 8.

[0026] The limiting component includes a limiting cylinder 23 fixedly mounted on the outer wall of the sleeve frame 8, and a sliding plate 24 is slidably assembled inside the limiting cylinder 23. A pull rod 26 and a positioning post 27 are respectively fixedly installed on the upper and lower end faces of the sliding plate 24, and the pull rod 26 and the positioning post 27 slide through the limiting cylinder 23. A first spring 25 is also provided between the upper end of the sliding plate 24 and the limiting cylinder 23. A number of right-angled trapezoidal grooves 28 are opened on the upper end face of the turntable 15, and the positioning post 27 slides into the inside of the right-angled trapezoidal groove 28. The inclined surface of the right-angled trapezoidal groove 28 allows the positioning post 27 to slide out, while the vertical surface on the opposite side can block the positioning post 27.

[0027] Working principle: In the initial state, the sleeve frame 8 is located directly above the support plate 3. When the material bucket is placed inside the sleeve frame 8, it can be placed on the support plate 3. At this time, the operator deflects the turntable 15 by using the lever 18 and pushes the positioning pin seat 17 through the arc-shaped through groove 16, which allows multiple push rods 12 to clamp the material bucket and fix it inside the sleeve frame 8. At this time, the motor 4 drives the winding wheel 5 to wind up the cable 11, so that the two sliding blocks 10 move the sleeve frame 8 upward through the rotating shaft 9. Since the cable 11 keeps pulling the sliding blocks 10 in an inclined upward state, it can pull the sliding blocks 10 to the horizontal position of the corner bracket 2. It should be noted that the push block 30 is located at the corner of the corner bracket 2 under the elastic pressure of the second spring 34. That is, as soon as the sliding block 10 is about to enter the horizontal part of the corner bracket 2, it will trigger the blocking block 31 and compress the second spring 34 through the push block 30. At this time, the sleeve frame 8 moves horizontally with the material barrel. During the horizontal movement, through the meshing of the gear 32 and the rack 33, the rotating shaft 9 can rotate the sleeve frame 8 and the internal material barrel, thereby realizing the pouring of the chemical raw materials in the material barrel to the feed port of the processing equipment.

[0028] After the unloading is completed, the motor 4 drives the take-up reel 5 to slowly reset and rotate. At this time, the cable 11 is slowly released, and the compressed second spring 34 pushes the sliding block 10 through the push block 30 and the blocking block 31. The sliding block 10, along with the rotating shaft 9, the sleeve frame 8, and the material bucket, retracts. When the sliding block 10 is elastically retracted to the corner of the corner bracket 2, the sliding block 10, the rotating shaft 9, the sleeve frame 8, and the material bucket will automatically slide down under the action of gravity, thus completing the reset after unloading.

[0029] Compared to the existing solution of feeding materials by moving the material bucket laterally along the plate chain, this solution offers greater stability and higher safety in its feeding method. Example 2: Please refer to Figures 3-5 This embodiment is a further explanation of Embodiment 1. The push rod 12 is hollow. A suction cup 13 is fixedly connected to one end face of the push rod 12 near the center of the sleeve frame 8. A hose 14 is fixedly connected to one end face of several push rods 12 away from the suction cup 13. A sealing cylinder 19 is fixedly connected to the upper end of the turntable 15. A through pipe 22 is fixedly connected between the sealing cylinder 19 and the hose 14. A piston disc 20 is slidably assembled inside the sealing cylinder 19. A threaded rod 21 is rotatably assembled on the top of the piston disc 20. The threaded rod 21 is threadedly assembled with the sealing cylinder 19. The suction cup 13 can be pressed against the surface of the material barrel. Then, the piston disc 20 can be pulled out to create negative pressure in the space between the suction cup 13 and the material barrel, thereby performing negative pressure suction and positioning of the material barrel.

[0030] The connection point between the through pipe 22 and the sealing cylinder 19 is located below the piston disc 20 to ensure that the piston disc 20 can move upward and suck up the suction cup 13.

[0031] In this embodiment: considering that the material barrel may be made of plastic, when the top rod 12 clamps the material barrel, it will cause the material barrel to deform, or during the lifting process, the chemical raw materials in the material barrel may be too heavy, causing the material barrel to detach between the top rods 12; In this solution, when the top rod 12 clamps the material barrel, the suction cup 13 can be tightly attached to the outer wall of the material barrel. Then, by rotating the threaded rod 21, the piston disc 20 moves upward, which can suck the air between the suction cup 13 and the material barrel, thereby achieving the effect of negative pressure adsorption. Through the negative pressure adsorption of multiple suction cups 13, the material barrel is clamped and sucked, which can further ensure the stability of the material barrel within the sleeve 8. Example 3: Please refer to Figure 8 and Figure 9This embodiment is a further explanation of Embodiment 1. The material pouring auxiliary unit includes an extended arc plate 35 fixedly disposed on the outer wall of the sleeve frame 8, and the extended arc plate 35 and the lever 18 are oppositely distributed. The two sides of the extended arc plate 35 are fixedly disposed between the sleeve frame 8 and the two side sealing plates 36. The bottom of the extended arc plate 35 is closed. The outer wall of the sleeve frame 8 is provided with an annular groove 37, and the annular groove 37 is located between the extended arc plate 35 and the two side sealing plates 36. The bottom of the sleeve frame 8 is fixedly disposed with a storage box 39. The bottom of the annular groove 37 is provided with a plurality of through holes 38, and the through holes 38 communicate with the storage box 39. The extended arc plate 35 and the two side sealing plates 36 form a closed frame, which covers the outer wall of the sleeve frame 8.

[0032] The extended arc plate 35 bends toward the side away from the center of the sleeve frame 8. When the sleeve frame 8 tilts with the material bucket, the extended arc plate 35 can guide or collect the chemical raw materials that spill out when the material bucket is tilted into the closed frame.

[0033] In this embodiment: when the chemical raw material is liquid, the initial slight tilt of the bucket will cause the liquid inside to flow down the outer wall of the bucket opening, rather than directly towards the feed inlet of the processing equipment. If the chemical liquid drips down the outer wall of the bucket, it can easily cause injury to the equipment or nearby personnel. Therefore, in this solution, the enclosed frame composed of the extended arc plate 35 and the sealing plate 36 can collect the chemical raw material that initially flows along the bucket wall and collect it into the storage tank 39 through the through hole 38, thus preventing the chemical raw material from spilling onto the equipment surface or nearby personnel. When the bucket is tilted at a larger angle, the liquid raw material inside the bucket can be poured directly into the feed inlet of the processing equipment, and the liquid raw material temporarily collected in the storage tank 39 can also be poured out again and guided by the extended arc plate 35 into the feed inlet of the processing equipment, thereby improving the safety of pouring.
