Referring to fig. 1 to 4, a plastic pellet feeding apparatus according to an embodiment includes a frame 1, and a hopper 2 and a driving device 3 are disposed on the frame 1, and are capable of intermittently feeding a conveying pipe to reduce a risk of blockage of the conveying pipe.
Referring to fig. 1 to 3, in particular, a feeding cylinder 21 is disposed at the bottom of the hopper 2. The top of the feed cylinder 21 communicates with the bottom of the hopper 2. A connection port 211 for connecting a delivery pipe is provided on the side wall of the supply cylinder 21. The frame 1 is used to support and mount the remaining components. The hopper 2 is arranged on the frame 1. The bottom of the hopper 2 is communicated with the feeding cylinder 21, so that the hopper 2 is connected with the inner cavity of the feeding cylinder 21 into a whole. In one embodiment, the feeding cylinder 21 is a vertically arranged cylinder structure, and the bottom of the feeding cylinder 21 is closed. The top of the feeding cylinder 21 is connected with the hopper 2. The connection port 211 is provided on the side wall of the cylindrical structure, and the connection port 211 is provided according to the structure of the delivery pipe.
The supply cylinder 21 is provided with a partition plate 22 and a rotatable supply wheel 23. The material feeding wheel 23 is provided with a material storage groove 231. The mouth of the hopper 231 faces upwardly towards the hopper 2. The sidewall of the storage tank 231 is provided with a discharge port 232. The feed wheel 23 rotates to intermittently communicate the connection port 211 with the discharge port 232 corresponding to any one of the hoppers 231. Specifically, the rotation axis of the material feeding wheel 23 is vertically arranged. The storage tank 231 is disposed along the radial direction of the supply wheel 23. The notch of the storage tank 231 is arranged on the top surface of the feeding wheel 23, and the discharge hole 232 is arranged at one end of the storage tank 231, which is far away from the rotating axis of the feeding wheel 23. In one embodiment, the number of reservoirs 231 is multiple. The material storage tanks 231 are arranged at intervals around the central line of the material supply wheel 23, and the side walls of the material storage tanks 231 are respectively provided with a material outlet 232. Specifically, the outer diameter of the feed wheel 23 is set to match the inner diameter of the feed cylinder 21. The gap between the side wall of the feed wheel 23 and the inner wall of the feed cylinder 21 is smaller than the size of the plastic particles. The material storage grooves 231 are uniformly distributed at intervals along the central line of the feeding wheel 23. Notches corresponding to the storage troughs 231 are arranged on the side wall of the feeding wheel 23 to be used as discharge holes 232. The feed wheel 23 rotates to sequentially circulate each discharge port 232 to align with the connection port 211, so that the connection port 211 is sequentially communicated with the corresponding stock tank 231.
Referring also to fig. 4, the partition 22 is disposed above the feeding wheel 23 near the connection port 211 for closing the notch of the corresponding storage tank 231 communicated with the connection port 211 through the discharge port 232. The driving device 3 is in transmission connection with the feeding wheel 23, and the driving device 3 can drive the feeding wheel 23 to rotate. Specifically, the partition 22 is fixedly disposed on the inner wall of the supply cylinder 21. The partition plate 22 isolates the corresponding storage groove 231 communicated with the connection port 211 from the hopper 2, and prevents plastic granules from falling into the corresponding storage groove 231. When the storage trough 231 deviates from the partition 22 along with the rotation of the feeding wheel 23, the plastic particles in the hopper 2 enter the storage trough 231 from the notch of the storage trough 231. The material storage groove 231 is communicated with the connecting port 211 through the material outlet 232 to be communicated with the conveying pipe, and the conveying pipe sucks the plastic particles in the corresponding material storage groove 231 each time, so that the conveying pipe is prevented from being blocked due to the fact that the conveying pipe sucks too many plastic particles once; the risk of blockage of the conveying pipe is reduced. In one embodiment, the partition 22 is in a fan shape, the large end of the partition 22 is connected to the inner wall of the supply cylinder 21, and the small end of the partition 22 extends to the center of the supply cylinder 21. In one embodiment, the partition 22 is further provided with a vent hole 221. The vent hole 221 allows air in the hopper 2 to enter the stock tank 231 communicating with the connection port 211. Specifically, the vent hole 221 is disposed above an end of the corresponding storage tank 231 away from the discharge port 232. It can be understood that the supply wheel 23 is rotatably disposed, and due to the manufacturing and assembling errors, a certain gap exists between the supply wheel 23 and the inner wall of the supply cylinder 21 and the partition plate 22 for air circulation, so that the conveying pipe can suck the plastic granules in the storage tank 231 by negative pressure, but the air flowing direction is different. The vent hole 221 is disposed away from the discharge port 232, so that air can enter the storage tank 231 to push plastic particles into the conveying pipe.
In one embodiment, the drive means 3 comprises a rotary drive 31 and a geneva gear 32. The rotary drive 31 is arranged on the machine frame 1. The dial 321 of the geneva gear 32 is provided on the output shaft of the rotary drive 31, and the geneva gear 322 of the geneva gear 32 is provided coaxially with the feed wheel 23. Each positioning arc structure of the grooved wheel 322 is arranged corresponding to each storage tank 231 one by one, and when the grooved wheel 322 is in rotation intermittence, the corresponding discharge port 232 is opposite to and communicated with the connecting port 211. The rotary drive 31 drives the applicator wheel 23 via the geneva gear 32. It will be appreciated that the Geneva gear 32 is an intermittent rotary mechanism. The rotary driver 31 drives the feed wheel 23 to rotate through the geneva gear 32, so that the feed wheel 23 rotates intermittently. The positioning arc structure of the grooved wheel 322 is arranged corresponding to the storage tank 231, so that when the storage tank 231 is communicated with the connecting port 211, the grooved wheel 322 is in a rotating gap, the communication keeping time of the storage tank 231 and the connecting port 211 is prolonged, the interval of plastic particles sucked by the conveying pipe is increased, and the plastic particles can be conveniently and fully sucked into the conveying pipe. In one embodiment, the rotary actuator 31 is an electric motor. It will be appreciated that the rotary drive 31 may also be implemented as a hydraulic motor, a pneumatic motor, a stepper motor, or the like.
According to the plastic particle feeding device in the above technical solution, when the storage tank 231 rotates along with the feeding wheel 23 and deviates from the partition 22, the plastic particles in the hopper 2 enter the storage tank 231 from the notch of the storage tank 231. When the feeding wheel 23 rotates to enable the storage tank 231 to be communicated with the conveying pipe through the discharge port 232 and the connecting port 211, the conveying pipe absorbs the plastic particles in the corresponding storage tank 231 every time, the blockage caused by the fact that the conveying pipe sucks too many plastic particles once is prevented, and the risk of blockage of the conveying pipe is reduced. The continuity and the stability of plastic particle feeding are improved.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
