Description

Technical Field

[0001] This utility model relates to the field of material conveying elbow technology, specifically an anti-clogging universal elbow for the discharge of a color sorter for plastic recycling. Background Technology

[0002] Plastics are polymer materials made from synthetic resins with various additives. They are lightweight, insulating, corrosion-resistant, and easy to process and mold, and are widely used in packaging, daily necessities, industrial manufacturing, and many other fields, bringing great convenience to people's lives and production. However, plastics are extremely difficult to degrade in the natural environment, and a large amount of waste plastics causes serious "white pollution," which harms the ecological environment. It is necessary to recycle plastics. During recycling, plastics are sent to crushing equipment for crushing to facilitate subsequent processing. These scraps can be reused after certain crushing, cleaning, drying, and color sorting to make new plastic products and achieve resource recycling. Color sorters are mainly used to sort plastic scraps by color to distinguish plastic particles of different colors.

[0003] After the color sorter separates different plastic scraps, an elbow is used to convey them onto the conveyor belt. Traditional elbows bend directly downwards towards the conveyor belt surface. In actual use, the plastic scraps are conveyed at varying speeds while the conveyor belt rotates at a fixed speed. When a large amount of plastic is discharged onto the conveyor belt surface in a short period, plastic scraps can accumulate, potentially clogging the elbow. Therefore, we propose an anti-clogging universal elbow for the discharge of a color sorter used in plastic recycling. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging universal elbow for the discharge of a color sorter for plastic recycling. By setting a bend that can be rotatably connected to the end of a straight pipe, it can be driven by a stepper motor to swing back and forth, so that the plastic fragments are dispersed and fall onto the conveyor belt. This avoids the accumulation of plastic fragments at the bottom of the bend and blockage caused by excessive plastic discharge in a short period of time. In addition, the rotating rod drives the lever to rotate, which also moves the fragments, further preventing plastic fragments from blocking the straight pipe. This solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a universal elbow for the discharge of a color sorter for plastic recycling, comprising a straight pipe and a bent pipe, wherein the bent pipe is rotatably fitted around the outer ring of the straight pipe, and the end of the bent pipe is bent downward; the end of the bent pipe is provided with a ring sleeve that is rotatably fitted around the outer ring of the straight pipe, and a rotating groove is provided on the inner side of the ring sleeve, and a rotating ring is provided around the outer ring of the straight pipe at the position of the rotating groove and is rotatably placed in the rotating groove, and a drive groove communicating with the outside is provided in the ring sleeve on the side of the rotating groove, and a toothed ring is fixed in the inner ring of the drive groove, and a stepper motor is installed on the surface of the straight pipe on the side of the ring sleeve, and a drive tooth that meshes with the toothed ring is installed on the drive shaft of the stepper motor.

[0006] By adopting the above technical solution, after the straight pipe is installed at the outlet of the color sorter through the flange, the plastic scraps fall onto the conveyor belt through the straight pipe and the curved pipe. The curved pipe is driven by the stepper motor to be in a swinging state, which can disperse the plastic scraps onto the surface of the conveyor belt and prevent the bottom of the curved pipe from being blocked. The set lever moves the inside of the straight pipe to avoid the problem of blockage inside the straight pipe.

[0007] Optionally, a drive motor is installed on the side surface of the straight tube, and the drive motor is connected to a rotatable rotating rod inside the straight tube. A lever is fixed on the outer ring of the rotating rod.

[0008] By adopting the above technical solution, when conveying plastic scraps, the rotation of the lever has a pushing effect on the inside of the straight pipe, preventing the plastic scraps from getting stuck in the straight pipe.

[0009] Optionally, multiple levers are provided, and the multiple levers are evenly distributed on the outer ring of the rotating rod.

[0010] By adopting the above technical solution, the setting of multiple levers has a better effect on moving the plastic fragments inside the straight tube.

[0011] Optionally, the outer ring surface of the rotating ring and the inner wall surface of the rotating groove are provided with rolling grooves at the aligned positions, and multiple rolling balls are rotatably filled between the rolling grooves of the rotating ring and the rolling grooves of the rotating groove.

[0012] By adopting the above technical solution, the bend can rotate more smoothly around the outer ring of the straight pipe.

[0013] Optionally, both the inner ring of the groove and the outer ring of the swivel have two grooves, and two rings of rolling balls are respectively filled between the two grooves.

[0014] By adopting the above technical solution, the setting of two-ring grooves and rolling balls makes the rotation of the structure connecting the straight pipe and the bent pipe more stable.

[0015] Optionally, a flange is provided at the end of the straight pipe, and the inner ring of the flange is connected to the inside of the straight pipe.

[0016] By adopting the above technical solution, the branch pipe can be connected to the discharge port of the color sorter through a flange.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: 1. The technical solution of this application sets up a bend that can be rotatably connected to the end of the straight pipe. It can be driven by a stepper motor to swing back and forth, so that the plastic fragments are dispersed and fall onto the conveyor belt. This avoids the excessive amount of plastic discharged in a short period of time, which would accumulate at the bottom of the bend and cause blockage. In addition, the rotating rod drives the lever to rotate, which also moves the fragments, further preventing the plastic fragments from blocking the straight pipe.

[0018] 2. The technical solution of this application provides grooves on the outer ring of the rotating ring and the inner ring of the rotating groove aligned with it, so that the grooves are evenly filled with rolling balls, which reduces the rotational resistance of the rotating ring in the rotating groove and is conducive to labor-saving rotation when bending the pipe.

[0021] Please see Figure 1-3 This utility model provides a technical solution: an anti-clogging universal elbow for the discharge of a color sorter for plastic recycling, including a straight pipe 1 and a bent pipe 2. The end of the straight pipe 1 is provided with a flange 12, and the inner ring of the flange 12 is connected to the inside of the straight pipe 1. In use, the straight pipe 1 is connected to the discharge port of the color sorter through the flange 12 at its end, and the plastic scraps after color sorting by the color sorter can enter the straight pipe 1.

[0022] The bend 2 is rotatably fitted around the outer ring of the straight pipe 1, and the end of the bend 2 is bent downward. Specifically, the end of the bend 2 connected to the straight pipe 1 is provided with a ring 3 that can be rotatably fitted around the outer ring of the straight pipe 1, and a rotating groove 31 is provided on the inner side of the ring 3. A rotating ring 11 is arranged around the outer ring of the straight pipe 1 at the position of the rotating groove 31 and can be rotatably placed in the rotating groove 31. When in use, when the bend 2 rotates around the outer ring of the straight pipe 1, the rotating ring 11 rotates in the rotating groove 31 and changes the orientation of the discharge port at the bottom of the bend 2.

[0023] In addition, the outer ring surface of the rotating ring 11 and the inner wall surface of the rotating groove 31 are both provided with grooves 6. Multiple rolling balls 61 are rolled between the grooves 6 of the rotating ring 11 and the grooves 6 of the rotating groove 31. The inner ring of the groove 6 and the outer ring of the rotating ring 11 are both provided with two rings of grooves 6, and two rings of rolling balls 61 are respectively filled between the two rings of grooves 6. When rotating, the rotating ring 11 and the rotating groove 31 are in contact through the rolling of the rollers, which can greatly reduce the frictional resistance during rotation and ensure the stability during rotation.

[0024] To drive the rotation of the bent tube 2, a drive groove 32 is provided inside the ring 3 on the side of the rotating groove 31. The side of the drive groove 32 is connected to the outside, and a gear ring 321 is fixed inside the drive groove 32. A stepper motor 4 is installed on the surface of the straight tube 1 on the side of the ring 3, and a drive tooth 41 that meshes with the inner ring of the gear ring 321 is installed on the drive shaft of the stepper motor 4. In actual use, the stepper motor 4 is connected to the industrial control computer, and the bent tube 2 can be driven to rotate through the drive tooth 41 and the gear ring 321, so that its bottom outlet swings back and forth above the conveyor belt, dispersing the plastic scraps onto the conveyor belt, avoiding excessive discharge of plastic scraps in a short time and accumulation on the conveyor belt to block the bottom of the bent tube 2.

[0025] Finally, a drive motor 5 is installed on the side surface of the straight tube 1. The drive motor 5 is connected to a rotating rod 51 inside the straight tube 1. A lever 511 is fixed on the outer ring of the rotating rod 51. Multiple levers 511 are evenly distributed on the outer ring of the rotating rod 51. Due to the horizontal arrangement of the straight tube 1, plastic scraps are easy to get stuck in the straight tube 1. When conveying plastic scraps, the drive motor 5 can drive the rotating rod 51 and the lever 511 to rotate, which has a dispersing effect on the plastic scraps passing through the straight tube 1, thus preventing plastic scraps from getting stuck in the straight tube 1.

[0026] In use, the end of the straight pipe 1 is connected to the discharge port of the color sorter through flange 12, so that the bottom of the bent pipe 2 is above the conveyor belt. The stepper motor 4 and drive motor 5 are both connected to the industrial control computer and powered on. During use, the plastic scraps after color sorting fall onto the surface of the conveyor belt through the straight pipe 1 and the bent pipe 2 and are transported away. In order to avoid a large amount of plastic scraps falling onto the surface of the conveyor belt at a fixed speed in a short period of time and accumulating and blocking the discharge at the bottom of the bent pipe 2, the stepper motor 4 rotates periodically in both directions. The drive gear 41 and the gear ring 321 work together to drive the bent pipe 2 to swing back and forth. During the swing, the discharge port at the bottom of the bent pipe is always kept above the conveyor belt, which can disperse the plastic scraps onto the surface of the conveyor belt. If there is any accumulation on the surface, it will block the bottom of the bent pipe 2 and affect its discharge. In addition, the drive motor 5 is also started to drive the rotating rod 51 and the lever 511 to rotate, which plays a prying role on the plastic scraps in the straight pipe 1, and avoids the accumulation of plastic scraps in the straight pipe 1 and causing blockage.
