Description

Technical Field

[0001] The invention relates to the technical field of sticky plastic particle production, in particular to a sticky plastic particle conveying and feeding device. Background Art

[0002] In the current production of plastic particles, negative pressure is used for transportation. Negative pressure is used to form a negative pressure airflow in the pipeline, and the particles in the hopper are sucked in for transportation and separated through the separation bucket. The suction fan needs to be stopped during separation, and then a swinging valve plate is set at the discharge port at the bottom of the separation bucket. When the suction is stopped, the valve plate will swing open due to its own weight, and the material will be discharged due to its own weight. However, the sticky plastic particles are relatively soft and have a certain viscosity on their surface. Therefore, when the separation bucket is full and the material is discharged, during the discharge process, the conveying pipe with a relatively small cross-section is always filled with accumulated materials. These accumulated materials may be squeezed into a ball in the conveying pipe due to their own viscosity. This will result in the inability to smoothly suck the plastic particles into the separation bucket when it is restarted later, and blockage may occur. In addition, the suction fan needs to be frequently started or stopped during material transportation, which affects efficiency. Summary of the invention

[0009] As a preferred solution, the partition rod is a round rod.

[0010] As a preferred solution, the dividing rod is a dividing rod with a triangular cross-section, and the tip of the dividing rod is arranged upward.

[0012] After adopting the above technical scheme, the effect of the present invention is as follows: since the sticky plastic particle conveying and feeding device includes a separation bucket, a separation net is arranged inside the separation bucket, and the separation net divides the separation bucket into an upper chamber and a lower chamber, a feeding pipe connected with the lower chamber is arranged on the side wall of the separation bucket, an exhaust pipe connected with the upper chamber is arranged at the upper end of the separation bucket, and the exhaust pipe is connected with a suction fan, and a blanking port is arranged at the lower end of the separation bucket, and a discharge barrel is also fixedly installed horizontally at the lower end of the separation bucket, one end of the discharge barrel is fixedly connected with the discharge port and is interconnected, and the other end of the discharge barrel is a discharge end and is provided with a discharge port, and a pushing screw is rotatably installed in the discharge barrel. Rod, the outer contour of the blade of the pushing screw matches the inner wall gap of the discharge barrel, and a driving motor for driving the pushing screw to rotate is arranged at the end of the discharge barrel; first, the suction fan sucks the separation bucket through the exhaust pipe. Since the blade of the pushing screw matches the inner wall gap in the discharge barrel, the airflow passing through is small, so air is sucked from the feed pipe to feed the material, and then the sticky plastic particles will enter the discharge barrel from the drop port, and then the driving motor drives the pushing screw to rotate, thereby driving the blade to rotate, and the pushing screw will continuously transport the sticky plastic particles and finally discharge them from the discharge port; the conveying and feeding device can continuously transport the material to avoid the suction fan stopping and causing the feed pipe to be blocked.

[0013] Furthermore, since the separation net is a conical separation net, the upper end of the separation net is fixed inside the top end of the separation bucket, and the tip of the separation net is arranged downward and points to the drop port; the conical separation net can make the sticky plastic particles fed by the feed pipe fall effectively, avoid sticking to the separation net, and prevent them from being sucked into the exhaust pipe.

[0014] Since the separation net is a conical separation net, a connecting flange is provided at the upper end of the separation net for convenient fixation with the top of the separation bucket, and the lower end of the separation net points to the center of the drop outlet; the connecting flange facilitates the installation of the separation net and improves the use effect.

[0015] Furthermore, since the separation bucket includes a first cylindrical barrel section, a first closing cone section is provided at the lower end of the first cylindrical barrel section, a second cylindrical barrel section is provided at the lower end of the first closing cone section, a second closing cone section is provided at the lower end of the second cylindrical barrel section, the drop port is provided at the lower end of the second closing cone section, the feed pipe is connected to the first cylindrical barrel section, and the first closing cone section is supported on the outside by a support frame; the connection between the first cylindrical barrel section and the first closing cone section can ensure that the sticky plastic particles can be effectively guided to fall after entering the separation bucket, and the second cylindrical barrel section can ensure that there is a certain storage space for the sticky plastic particles after falling, and then the second closing cone section further guides the sticky plastic particles in the second cylindrical barrel section to fall, so as to prevent the material from falling too fast and ensure the stability of the material falling.

[0016] Furthermore, since a plurality of partition rods are arranged at the discharge port on the second closing cone section, the gaps between the partition rods constitute a discharge gap that is convenient for the discharge of plastic ions; blocking is performed at the discharge port so that the sticky plastic particles slowly fall into the discharge barrel at the discharge port, which can reduce the airflow of the discharge barrel entering the separation bucket and ensure the extraction efficiency.

[0017] Furthermore, since the partition rod is a round rod, it blocks the falling material and prevents the sticky plastic particles from adhering to the partition rod, thereby ensuring the stability of the falling material.

[0018] Furthermore, since the dividing rod has a triangular cross section and the tip of the dividing rod is arranged upward, it can also effectively block the falling of materials and also avoid the adhesion of sticky plastic particles.

[0019] Since the dividing rod is arranged on a dividing ring, a lower connecting flange is arranged on the discharging barrel, and an upper connecting flange is arranged at the lower end of the second closing cone section, the upper connecting flange and the lower connecting flange can be detachably fixed and the dividing ring is pressed and fixed, ensuring the stable installation of the dividing rod.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below through specific examples.

[0027] like Figures 1 to 4As shown, a viscous plastic particle conveying and feeding device comprises a separation bucket 1, wherein a separation net 6 is arranged inside the separation bucket 1, and the separation net 6 divides the separation bucket 1 into an upper chamber 7 and a lower chamber 8, and a feeding pipe 9 connected to the lower chamber 8 is arranged on the side wall of the separation bucket 1, and an exhaust pipe 10 connected to the upper chamber 7 is arranged at the upper end of the separation bucket 1, and the exhaust pipe 10 is connected to a suction fan, and a drop port 11 is arranged at the lower end of the separation bucket 1, and the separation A discharge barrel 12 is also fixedly installed horizontally at the lower end of the hopper 1. One end of the discharge barrel 12 is fixedly connected to the drop port 11 and interconnected. The other end of the discharge barrel 12 is the discharge end and is provided with a discharge port 13. A push screw 14 is rotatably installed in the discharge barrel 12. The outer contour of the blade 15 of the push screw 14 is clearance-matched with the inner wall of the discharge barrel 12. A drive motor 16 for driving the push screw 14 to rotate is provided at the end of the discharge hopper.

[0028] In this embodiment, the separation bucket 1 is supported and installed by a support frame 17. When the suction fan sucks the separation bucket 1, a negative pressure state is formed in the separation bucket 1, so the feed pipe 9 can perform suction, and the outer contour of the blade 15 of the pushing screw 14 is matched with the inner wall gap of the discharge barrel 12, the air intake in the discharge port 13 will be reduced to avoid affecting the air extraction of the feed pipe 9. In this way, the separation bucket 1 can continuously feed and discharge materials, and the discharge barrel 12 can continuously discharge materials, thereby ensuring the efficiency of conveying and loading.

[0029] like Figure 2 As shown, the separation net 6 is a conical separation net 6, the upper end of the separation net 6 is fixed inside the top end of the separation bucket 1, and the tip of the separation net 6 is set downward and points to the drop port 11; since the separation net 6 is conical, when the feed pipe 9 feeds, the sticky plastic particles will contact the separation net 6, and the conical surface can effectively guide the sticky plastic particles, so that the sticky plastic particles can fall accurately, while preventing them from being sucked into the exhaust pipe 10.

[0030] Furthermore, the separation net 6 is a conical separation net 6, and the upper end of the separation net 6 is provided with a connecting flange 18 for convenient fixation with the top of the separation bucket 1, and the lower end of the separation net 6 points to the center of the drop port 11; the installation of the separation net 6 is facilitated by the connecting flange 18, and the separation net 6 is conical, and the arc transition of the surface is smoother, so that the drop after feeding is more accurate, thereby improving the use effect.

[0031] like Figure 1 and Figure 2As shown, the separation bucket 1 includes a first cylindrical barrel section 2, a first closing cone section 3 is arranged at the lower end of the first cylindrical barrel section 2, a second cylindrical barrel section 4 is arranged at the lower end of the first closing cone section 3, a second cylindrical barrel section 5 is arranged at the lower end of the second cylindrical barrel section 4, the drop port 11 is arranged at the lower end of the second closing cone section 5, the feed pipe 9 is connected to the first cylindrical barrel section 2, and the first closing cone section 3 is supported on the outside by a support frame 17; the connection between the first cylindrical barrel section 2 and the first closing cone section 3 can ensure that the sticky plastic particles can be effectively guided to fall after entering the separation bucket 1, the second cylindrical barrel section 4 can ensure that there is a certain storage space for the sticky plastic particles after falling, and then the second closing cone section 5 further guides the sticky plastic particles in the second cylindrical barrel section 4 to fall, so as to prevent the material from falling too fast and ensure the stability of the material falling.

[0032] like Figure 2 and Figure 3 As shown, a plurality of partition rods 19 are arranged on the second closing cone section 5 at the outlet 11, and the gaps between the partition rods 19 constitute a material drop gap for facilitating the drop of plastic ions; blocking is performed at the outlet 11, so that the sticky plastic particles slowly fall into the discharge barrel 12 at the outlet 11, which can reduce the airflow of the discharge barrel 12 entering the separation bucket 1, thereby ensuring the extraction efficiency.

[0033] Furthermore, the partition rod 19 is a round rod; the round rod has a smooth surface, which blocks the falling of materials and prevents the sticky plastic particles from adhering to the partition rod, thereby ensuring the stability of the falling of materials.

[0034] Of course, another solution can also be adopted, in which the dividing rod 19 is a dividing rod 19 with a triangular cross-section, and the tip of the dividing rod 19 is set upward; the inclined surfaces on both sides of the triangular dividing rod 19 are also guiding, guiding the sticky plastic particles, while reducing the area of ​​falling materials, effectively blocking the falling materials, and avoiding the adhesion of sticky plastic particles.

[0035] In this embodiment, the dividing rod 19 is arranged on a dividing ring 20, the discharging barrel 12 is provided with a lower connecting flange 21, and the lower end of the second closing cone section 5 is provided with an upper connecting flange 22. The upper connecting flange 22 and the lower connecting flange 21 are detachably fixed and the dividing ring 20 is pressed and fixed; the upper connecting flange 22 and the lower connecting flange 21 are detachably fixed by bolts, so that the distribution hopper and the discharging barrel 12 can be firmly connected, and at the same time, the stable installation of the dividing rod can be ensured.

[0036] The working principle of this embodiment is as follows: first, the suction fan sucks the separation bucket 1 through the exhaust pipe 10, and the feed pipe 9 is fed, and the sticky plastic particles will enter the discharge barrel 12 from the drop port 11, and the partition rod 19 will block the sticky plastic particles from dropping, and then the driving motor 16 drives the pushing screw 14 to rotate, and then drives the blades 15 to rotate, and the pushing screw 14 will continuously transport the sticky plastic particles and finally discharge them from the discharge port 13.

[0037] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the scope of protection defined by the claims of the present invention.
