Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to an automatic feeding device for producing modified recycled plastic particles. Background Art

[0002] Modified plastics are intermediate products in the petrochemical industry chain. They are mainly made of five general-purpose plastics and five engineering plastics as plastic matrices. They have the characteristics of flame retardancy, impact resistance, high toughness, and easy processing. Modified plastics need to be loaded using a feeding device during the production process.

[0003] According to a disclosed feeding device for preparing plastic particles (publication number: CN214027103U), in the above application, the first motor is started to drive the first bevel gear to rotate, which in turn drives the second bevel gear and the rotating rod to rotate, and drives the spiral surface to rotate, so that the material in the containing frame can be transported to the cylinder through the channel, and then transported to the discharge frame through the spiral surface and the discharge pipe, and then the plastic particles are delivered to the production equipment through the discharge frame.

[0004] The device uses a feeding frame to drop plastic particles into the interior of the equipment. However, after the modified plastic is crushed into plastic particles, they are basically irregular in shape. The friction between the irregularly shaped plastic particles is relatively large, and they are easily stuck inside the feeding frame, resulting in the plastic particles being unable to be discharged downward normally, causing feeding interruptions and affecting subsequent equipment production. Summary of the Invention

[0005] The purpose of the utility model is to provide an automatic feeding device for the production of modified recycled plastic particles to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic feeding device for the production of modified recycled plastic particles, comprising a top plate, a conveying cylinder fixedly mounted on the bottom of the top plate, a feed hopper fixedly mounted on the outer wall of the conveying cylinder, a discharge pipe fixedly mounted on the outer wall of the top plate, a motor fixedly mounted on the bottom of the top plate, a rotating shaft fixedly mounted on the output end of the motor, an end of the rotating shaft away from the motor passing through the top plate, an auger shaft rotatably connected to the inner wall of the conveying cylinder, the top of the auger shaft passing through the top plate and passing through a transmission belt. The belt is connected to the rotating shaft in a transmission manner. A discharge hopper is fixedly installed at the bottom of the discharge pipe. A discharge port is opened at the bottom of the discharge hopper. A dredging mechanism for dredging the discharge port is provided on the discharge hopper. The discharge port can be dredged by setting the dredging mechanism to prevent plastic particles from getting stuck inside the discharge port. A knocking mechanism is provided on the outer wall of the conveying cylinder. The knocking mechanism can be provided to shake the plastic particles inside the discharge pipe downward and accelerate them to be discharged downward into the interior of the discharge hopper to prevent plastic particles from getting stuck inside the discharge pipe.

The slide plate is provided in conjunction with the push rod to dredge the lower hopper;

[0008] The sliding frame is slidably connected to the side wall of the top plate. An L-rod is fixedly installed at the bottom of the sliding frame. The end of the L-rod away from the sliding frame is attached to the inner wall of the chute. By arranging the L-rod in conjunction with the chute, the slide plate can be driven to slide back and forth on the outer wall of the lower hopper.

[0009] The eccentric wheel is fixedly mounted on the outer wall of the rotating shaft, and the outer wall of the eccentric wheel is fitted on the inner wall of the sliding frame. The sliding frame can be squeezed back and forth by arranging the eccentric wheel.

[0010] Preferably, the knocking mechanism includes a rotating drum, which is rotatably connected to the outer wall of the conveying drum, and a spiral groove is provided on the rotating drum.

[0014] Preferably, the interior of the feed hopper is communicated with the interior of the conveying cylinder, and the interior of the discharge pipe is communicated with the interior of the conveying cylinder.

[0015] Compared with the prior art, the present invention provides an automatic feeding device for the production of modified recycled plastic particles, which has the following beneficial effects:

[0016] 1. The automatic feeding device for the production of modified recycled plastic particles can drive the ejector rod to move back and forth synchronously inside the discharge port through the rotation of the rotating shaft in conjunction with the eccentric wheel, slide frame, L-rod, chute, and slide plate.

[0023] like Figures 1-4The hopper 3 is fixedly mounted on the bottom of the top plate 1, and a feed hopper 3 is fixedly mounted on the outer wall of the feed hopper 3. The interior of the feed hopper 3 is communicated with the interior of the feed hopper 3, and the plastic particles are poured into the feed hopper 3. At this time, the plastic particles will fall into the interior of the feed hopper 3, and the outer wall of the top plate 1 is fixedly mounted on the outer wall of the top plate 1. The interior of the feed hopper 3 is communicated with the interior of the conveying cylinder 2. When the plastic particles are lifted to the feed hopper 4, they will fall into the interior of the feed hopper 4 and fall into the interior of the lower hopper 9 through the feed hopper 4. A motor 5 is fixedly mounted on the bottom of the top plate 1, and a rotating shaft 6 is fixedly mounted on the output end of the motor 5. The end of the rotating shaft 6 away from the motor 5 passes through the top plate 1, and the rotating shaft 6 is rotatably connected to the penetration point of the top plate 1. When the motor 5 is started, the rotating shaft 6 is driven to rotate, and the inner wall of the conveying cylinder 2 is rotatably connected to the auger shaft 7. The rotation of the auger shaft 7 can push the plastic particles in the feed hopper 3 to the top of the conveying cylinder 2 The top of the auger shaft 7 passes through the top plate 1 and is connected to the rotating shaft 6 through a transmission belt 8. The auger shaft 7 is rotatably connected to the penetration of the top plate 1. When the rotating shaft 6 rotates, the transmission belt 8 can drive the auger shaft 7 to rotate. A hopper 9 is fixedly installed at the bottom of the discharge pipe 4. A discharge port 10 is provided at the bottom of the discharge pipe 9. The plastic particles inside the discharge hopper 9 can be discharged downward through the discharge port 10, so that the plastic particles can be fed into the interior of the production equipment. A dredging mechanism 11 for dredging the discharge port 10 can be dredged by setting the dredging mechanism 11 to dredge the discharge port 10, so as to avoid the plastic particles getting stuck inside the discharge port 10, so that the discharge hopper 9 can be fed stably. The outer wall of the conveying cylinder 2 is provided with a knocking mechanism 12, which can vibrate the plastic particles inside the discharge pipe 4 downward and accelerate the downward discharge into the interior of the discharge hopper 9, so as to avoid the plastic particles getting stuck inside the discharge pipe 4, so that the plastic particles can fall stably into the interior of the discharge hopper 9.

[0024] The above-mentioned dredging mechanism 11 includes a slide plate 111, a sliding frame 112, an eccentric wheel 113, a push rod 114, a chute 115, and an L rod 116; the slide plate 111 is slidably connected to the outer wall of the lower hopper 9, and the bottom of the slide plate 111 is fixedly installed with a push rod 114. When the slide plate 111 slides back and forth on the outer wall of the lower hopper 9, it will drive the push rod 114 to move back and forth synchronously inside the lower feeding port 10. At this time, the push rod 114 will squeeze the plastic particles inside the lower feeding port 10 into the lower feeding port 10. The push rod 114 can dredge the lower feeding port 10 to prevent the plastic particles from getting stuck inside the lower feeding port 10. The side wall of the slide plate 111 is provided with a chute 115, and the slide frame 11 2 is slidably connected to the side wall of the top plate 1. An L-rod 116 is fixedly installed at the bottom of the sliding frame 112. The end of the L-rod 116 away from the sliding frame 112 is in contact with the inner wall of the chute 115. When the sliding frame 112 slides back and forth on the side wall of the top plate 1, it drives the L-rod 116 to be in contact with the inner wall of the chute 115 and to move back and forth synchronously. At this time, the L-rod 116 reciprocates and squeezes the chute 115, causing the slide plate 111 to slide up and down on the outer wall of the lower hopper 9. The eccentric wheel 113 is fixedly installed on the outer wall of the rotating shaft 6. The outer wall of the eccentric wheel 113 is in contact with the inner wall of the sliding frame 112. When the eccentric wheel 113 rotates, it pushes and pulls the sliding frame 112 back and forth, causing the sliding frame 112 to slide back and forth on the side wall of the top plate 1.

[0025] The knocking mechanism 12 includes a rotating drum 121, a spiral groove 122, a rubber rod 123, a steel ball 124, and a guide rod 125; the rotating drum 121 is rotatably connected to the outer wall of the conveying drum 2, and a spiral groove 122 is provided on the rotating drum 121. The outer wall of the rotating drum 121 is fixedly mounted with a rubber rod 123, and the end of the rubber rod 123 away from the rotating drum 121 is fixedly mounted with a steel ball 124. During the rotation of the rotating drum 121, the rubber rod 123 can be used to drive the steel ball 124 to repeatedly knock on the bottom of the discharge pipe 4. The outer wall of the steel ball 124 is attached to the bottom of the discharge pipe 4. The steel ball 124 repeatedly hits the bottom of the discharge pipe 4 to shake the plastic particles inside it downward, so that the plastic particles inside the discharge pipe 4 can be accelerated to discharge downward into the interior of the discharge hopper 9, avoiding the plastic particles from getting stuck inside the discharge pipe 4. A guide rod 125 is fixedly installed at the bottom of the slide frame 112, and the outer wall of the guide rod 125 fits against the inner wall of the spiral groove 122. When the slide frame 112 slides back and forth on the side wall of the top plate 1, it will drive the guide rod 125 to move back and forth synchronously. At this time, the guide rod 125 will reciprocally squeeze the spiral groove 122, causing the rotating drum 121 to rotate back and forth.

[0026] Working principle: Pour the plastic granules into the inside of the feed hopper 3, at this time the plastic granules will fall into the inside of the conveying cylinder 2, and then start the motor 5 to drive the rotating shaft 6 to rotate. While the rotating shaft 6 rotates, the transmission belt 8 can drive the auger shaft 7 to rotate. The rotation of the auger shaft 7 can lift the plastic granules inside the feed hopper 3 to the top of the conveying cylinder 2. When the plastic granules are lifted to the discharge pipe 4, they will fall into the inside of the discharge pipe 4 and fall into the inside of the lower hopper 9 through the discharge pipe 4. Finally, they are discharged downward through the discharge port 10, so that the plastic granules can be fed into the interior of the production equipment. At the same time, the rotating shaft 6 will drive the eccentric wheel 113 to rotate synchronously while rotating, and the eccentric wheel 113 will rotate while rotating. The sliding frame 112 is pushed and pulled repeatedly, so that the sliding frame 112 slides back and forth on the side wall of the top plate 1. At this time, the sliding frame 112 will drive the L rod 116 to fit the inner wall of the inclined groove 115 and move back and forth synchronously. At this time, the L rod 116 will reciprocate and squeeze the inclined groove 115, so that the slide plate 111 slides back and forth on the outer wall of the lower hopper 9. At the same time, the slide plate 111 will drive the ejector rod 114 to move back and forth synchronously inside the lower feeding port 10. At this time, the ejector rod 114 will squeeze the plastic particles inside the lower feeding port 9 into the interior of the lower feeding port 10. The ejector rod 114 can be used to dredge the lower feeding port 10 to prevent the plastic particles from getting stuck inside the lower feeding port 10, so that the lower feeding hopper 9 can be stably fed, which is beneficial to subsequent production.

[0027] When the sliding frame 112 slides back and forth on the side wall of the top plate 1, it will drive the guide rod 125 to move back and forth synchronously. At this time, the guide rod 125 will squeeze the spiral groove 122 back and forth, causing the rotating drum 121 to rotate back and forth. During the rotation of the rotating drum 121, the rubber rod 123 can be used to drive the steel ball 124 to repeatedly knock on the bottom of the discharge pipe 4. The repeated knocking of the bottom of the discharge pipe 4 by the steel ball 124 can shake the plastic particles inside it downward, so that the plastic particles inside the discharge pipe 4 can be accelerated to discharge downward into the interior of the discharge hopper 9, avoiding the plastic particles from getting stuck inside the discharge pipe 4, so that the plastic particles can stably fall into the interior of the discharge hopper 9.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
