Description

Technical Field

[0001] The utility model relates to a feeding and conveying device, in particular to a feeding and conveying device for recycled plastic particles. Background Art

[0002] Recycled plastic particles refer to plastic particles made through processes such as cleaning, crushing, and melting after recycling waste plastic products. These particles can be used again in the production of new plastic products to achieve the recycling of resources. The last two processes of recycled plastic particles are granulation and screening and packaging. In these two processes, a feeding and conveying device is required to convey the plastic particles discharged from the granulator to the screening machine.

[0003] For the existing feeding and conveying device for recycled plastic particles, although it can achieve the conveying of plastic particles, there are still deficiencies in actual use. For example, when the conveyor belt conveys plastic particles, the plastic particles may accumulate at the edge of the conveyor belt. The accumulated particles may generate additional friction between the conveyor belt and the support structure, resulting in increased wear of the conveyor belt and the support structure and shortening the service life. In addition, the accumulated particles may get stuck between the conveyor belt and the support mechanism, hindering the normal operation of the conveyor belt and reducing the conveying efficiency.

[0004] Therefore, there is a particular need for a feeding and conveying device for recycled plastic particles to solve the above problems. Summary of the Utility Model

[0005] In order to overcome the shortcomings of the existing feeding and conveying device for recycled plastic particles, during the process of conveying plastic particles, the plastic particles may accumulate at the edge of the conveyor belt, causing additional friction and wear, and may also get stuck between the conveyor belt and the support mechanism, hindering the normal operation of the conveyor belt and reducing the conveying efficiency, the technical problem to be solved is: to provide a feeding and conveying device for recycled plastic particles.

The right side of the mounting frame is fixedly connected with a material box, and the material box is located above the rotating frame. The right side of the material box is fixedly connected with a feeding port. The front left side of the mounting frame is provided with a mounting plate, and a motor is installed at the lower part of the mounting plate. Two conveying rollers are rotatably connected to the mounting frame. A conveyor belt is rotatably connected between the two conveying rollers, and pulley assemblies are arranged between the front and rear ends. The output shaft of the motor passes through the left side of the pulley assembly and is fixedly connected with the left conveying roller. It further comprises a scraping mechanism, and the scraping mechanism is arranged on the mounting frame.

The pulley assembly is fixedly connected with a top block. The mounting frame is fixedly connected with guide rods distributed front and back. The outside of the guide rod is slidably connected with a sliding plate, and a first spring for assisting in resetting is sleeved. The two ends of the first spring are respectively connected with the sliding plate and the guide rod. The lower part of the sliding plate contacts the upper part of the top block, so that the top block can squeeze the sliding plate. The scraping block in contact with the surface of the conveyor belt is slidably connected inside the sliding plate, and symmetrically distributed second springs are connected between the scraping block and the sliding plate.

[0008] In one embodiment, it further comprises a stirring mechanism. A stirring mechanism for stirring plastic pellets is arranged inside the material box. The stirring mechanism comprises an electric push rod, a stirring plate, a limiting rod and a connecting plate.

[0021] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0022] Embodiment: A feeding and conveying device for recycled plastic particles, as shown in Figures 1-6 the figure, which includes a cylinder 1, a support rod 2, a rotating frame 201, a blanking plate 3, a conveyor belt 4, a mounting plate 401, a motor 402, a conveying roller 403, a partition 404, a pulley assembly 5, a material box 10, a feeding port 1001, and a mounting frame 11. The left side of the mounting frame 11 is connected to the support rod 2 by welding, and the right side is rotatably connected to the rotating frame 201. The left side of the rotating frame 201 is connected to the cylinders 1 distributed front and back by bolts. The telescopic rods of the two cylinders 1 are respectively fixedly connected to the front and back ends of the support rod 2, and the bottom surface of the cylinder 1 and the bottom surface of the rotating frame 201 are on the same horizontal plane, and anti-slip blocks for increasing friction are provided to ensure stable contact of the cylinder 1 and the rotating frame 201 with the ground. The left side of the mounting frame 11 is connected to the blanking plate 3 by welding, and the blanking plate 3 is located to the left of the support rod 2 and is inclined, which can achieve a good material guiding effect. The right side of the mounting frame 11 is connected to the material box 10 by welding, and the material box 10 is located above the rotating frame 201. The right side of the material box 10 is connected to the feeding port 1001 by welding. The left front side of the mounting frame 11 is connected to the mounting plate 401 by bolts. The lower part of the mounting plate 401 is connected to the motor 402 by bolts. Two conveying rollers 403 are rotatably connected to the mounting frame 11. A conveyor belt 4 is rotatably connected between the two conveying rollers 403, and pulley assemblies 5 are provided between the front and back ends. The output shaft of the motor 402 passes through the left side of the pulley assembly 5 and is fixedly connected to the left conveying roller 403. A plurality of partitions 404 evenly spaced are connected to the surface of the conveyor belt 4 by adhesion for separating plastic particles. A scraping mechanism is also included. A scraping mechanism is provided on the mounting frame 11 for scraping off the plastic particles at the edge of the conveyor belt 4.

[0023] As shown in Figures 1-4As shown in the figure, the scraping mechanism includes a first spring 6, a top block 7, a sliding plate 8, a second spring 801, a scraping block 802 and a guide rod 9. The top block 7 is connected to the pulley assembly 5 by adhesion. The guide rod 9 distributed front and back is connected to the mounting frame 11 by welding. The outer part of the guide rod 9 is slidably connected with the sliding plate 8, and a first spring 6 for assisting in resetting is sleeved thereon. The two ends of the first spring 6 are respectively connected to the sliding plate 8 and the guide rod 9. The lower part of the sliding plate 8 contacts the upper part of the top block 7, so that the top block 7 can squeeze the sliding plate 8. A scraping block 802 in contact with the surface of the conveyor belt 4 is slidably connected inside the sliding plate 8. Symmetrically distributed second springs 801 are connected between the scraping block 802 and the sliding plate 8. A protective pad is provided on the contact surface between the scraping block 802 and the conveyor belt 4 to prevent the scraping block 802 from scraping the surface of the conveyor belt 4. The partition plate 404 is made of a relatively soft material, such as silicone. While separating the materials, it can be squeezed by the scraping block 802 moving leftward to ensure that the scraping block 802 can move leftward normally. Moreover, an inclined surface is provided on the right side of the scraping block 802, so that when the scraping block 802 moves rightward, it can be squeezed by the partition plate 404 and move upward, reducing the moving resistance.

[0024] Read Figures 5-6 As shown in the figure, it further includes a stirring mechanism. A stirring mechanism for stirring plastic particles is arranged inside the material frame 10. The stirring mechanism includes an electric push rod 12, a stirring plate 13, a limiting rod 14 and a connecting plate 15. The upper electric push rod 12 is connected to the rear side of the material frame 10 by bolts, and two stirring plates 13 are slidably connected inside. The bottom surface of the stirring plate 13 contacts the inner bottom surface of the material frame 10 to facilitate fully stirring the plastic particles inside the material frame 10. Moreover, a plurality of square grooves distributed in a straight line are provided on the stirring plate 13 for accommodating the discharged plastic particles after dispersion. The right stirring plate 13 is fixedly connected to the telescopic rod of the electric push rod 12. The limiting rod 14 is connected to the front side of the material frame 10 by welding. A connecting plate 15 is rotatably connected between the two stirring plates 13 and the limiting rod 14, and the connecting plate 15 is made of steel with high strength to ensure stable pulling and pushing of the left stirring plate 13.

[0025] When the device needs to be used, first turn on the cylinder 1, control the telescopic rod of the cylinder 1 to extend or retract to an appropriate length, drive the support rod 2 to drive the mounting frame 11, rotate clockwise or counterclockwise to an appropriate angle, adjust the heights of the blanking plate 3 and the material box 10. After the adjustment is completed, turn off the cylinder 1, place the device between the granulator and the screening machine, make the blanking plate 3 face directly above the feed bin of the screening machine, then connect the discharge port of the granulator to the feed port 1001, operate the granulator and the screening machine to run, and turn on the motor 402 and the electric push rod 12. Control the rotation speed of the output shaft of the motor 402, and control the telescopic rod of the electric push rod 12 to retract and extend back and forth. The granulator conveys the manufactured plastic particles from the feed port 1001 into the material box 10. When the telescopic rod of the electric push rod 12 continuously retracts and extends, it drives the right stirring plate 13 to continuously move backward and forward, causing it to pull the connecting plate 15 to rotate and push the connecting plate 15 to reverse. The connecting plate 15 then pulls the left stirring plate 13 to move forward and pushes the left stirring plate 13 to move backward. In this way, the two stirring plates 13 move alternately, fully stirring the plastic particles in the material box 10. The plastic particles after being stirred and dispersed are discharged from the square groove of the stirring plate 13 and fall to the right side of the conveyor belt 4. The partition plate 404 plays a role in separating the plastic particles, preventing the plastic particles from being mixed with each other or arranged in a disorderly manner during the conveying process. At this time, the output shaft of the motor 402 drives the left conveying roller 403 to rotate, causing it to drive the right conveying roller 403 to rotate through the pulley assembly 5, and then driving the conveyor belt 4 to rotate to convey the plastic particles to the left, so that the plastic particles fall onto the blanking plate 3 and then fall into the feed bin of the screening machine along the inclined surface of the blanking plate 3. During the conveying process, the pulley assembly 5 drives the top block 7 to rotate, intermittently squeezing the slide plate 8 to move leftward, and the first spring 6 is compressed accordingly. The slide plate 8 drives the scraping block 802 to move leftward together, scraping off the plastic particles on the edge of the conveyor belt 4. When the top block 7 intermittently stops squeezing the slide plate 8, the slide plate 8 just moves leftward to the limit position, completing one scraping operation. At the same time, the first spring 6 returns to its original state, prompting the slide plate 8 to drive the scraping block 802 to move rightward to reset. During the reset process, the inclined surface on the right side of the scraping block 802 contacts the partition plate 404 and is squeezed by the partition plate 404 to move upward, and the second spring 801 is compressed accordingly, so as to reduce the resistance when the scraping block 802 moves rightward. In this way, the scraping block 802 intermittently scrapes off the plastic particles on the edge of the conveyor belt 4, avoiding the accumulation of plastic particles on the edge of the conveyor belt 4. When all the plastic particles discharged from the granulator are conveyed, turn off the motor 402 and the electric push rod 12.

Therefore, the scope of the present invention should be limited only by the appended claims.
