[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] like Figure 1-5 As shown, a plastic powder fine sieving and grinding device includes a sieve plate 1, a discharge port 2, a limiting component 3, and an anti-clogging component 4. The sieve plate 1 is connected to the discharge port of a plastic coarse abrasive transfer and conveying device, wherein the sieve plate 1 is as follows: Figure 1 As shown in the circular shell, it is used to hold plastic powder transferred by the plastic coarse abrasive transfer and conveying device. The upright sieve plate 1 is used to prevent the plastic powder from falling off when shaking and sieving. The discharge port 2 is connected to one side of the sieve plate 1, and the discharge port 2 and the sieve plate 1 are connected to each other. It is used to re-enter the plastic coarse abrasive transfer and conveying device to transport unqualified plastic powder to the plastic granule coarse grinding device for grinding again.
[0029] To prevent splashing during discharge from outlet 2, a limiting component 3 is detachably inserted into outlet 2 using bolts, threaded grooves, or similar means. The limiting component 3 is as follows: Figure 3 The device is designed in a U-shape and is inserted into the outlet 2 to seal the outlet 2, preventing plastic powder from splashing from the outlet 2 at the position of the insertion limiting member 3. An anti-blocking member 4 is slidably inserted into the limiting member 3. The anti-blocking member 4 works back and forth in the limiting member 3 to clear the outlet 2. The anti-blocking member 4 moves within the limiting member 3 to clear the outlet 2.
[0030] In order to ensure that the anti-blocking component 4 can slide back and forth within the limiting component 3 to clear the discharge port 2, two insertion slots 31 are provided in the limiting component 3, and the insertion slots 31 are partially inserted into the anti-blocking component 4.
[0031] The anti-blocking component 4 includes a connecting rod 42 that can be slidably inserted into the insertion slot 31, wherein the connecting rod 42 is as follows: Figure 3 and Figure 5 The design shown is cylindrical, and the insertion slot 31 is circular. The diameter of the insertion slot 31 is slightly larger than the diameter of the connecting rod 42. The insertion slot 31 provides space for the connecting rod 42 to slide back and forth. Both ends of the connecting rod 42 pass through the side of the insertion slot 31.
[0032] The end of the connecting rod 42 located outside the discharge port 2 is connected to a push plate 41, and the four sides of the push plate 41 are all longer than the four sides of the limiting member 3.
[0033] The end of the connecting rod 42 located inside the discharge port 2 is rotatably connected to a rotating plate 43. The farthest distance of the end of the rotating plate 43 is less than the length inside the discharge port 2. While the rotating plate 43 moves with the connecting rod 42 inside the discharge port 2, it will rotate around the axis of the connecting rod 42.
[0034] Specifically, when material is discharged from the discharge port 2, the rotating blade 43 abuts against the side of the limiting member 3. At this time, the push plate 41 is located at the position furthest away from the limiting member 3. When a blockage occurs in the discharge port 2, the push plate 41 is pushed. At this time, the push plate 41 is like... Figure 2 As shown, it fits into the limiting part 3. At the same time, the connecting rod 42 will drive the rotating plate 43 to move in the discharge port 2. At this time, since the rotating plate 43 is rotatably connected, it will be rotated under force when it is inside the insertion side cavity 21, which will increase the unblocking effect in the discharge port 2.
[0035] The overall effect achieved by embodiment one is that the sieve plate 1, as shown in the figure, is as follows: Figure 1 As shown in the circular shell, it is used to hold plastic powder transferred by the plastic coarse abrasive conveyor. The upright sieve plate 1 is used to prevent the plastic powder from falling off during shaking and sieving. The discharge port 2 is connected to the sieve plate 1, and is used to re-enter the plastic coarse abrasive conveyor to transport unqualified plastic powder to the plastic granule coarse grinding device for further grinding. When discharging in the discharge port 2, the rotating blade 43 will abut against the side of the limiting member 3. At this time, the push plate 41 is located at the position furthest away from the limiting member 3. When the discharge port 2 is blocked, the push plate 41 is pushed. At this time, the push plate 41 is like... Figure 2 As shown, it fits into the limiting part 3. At the same time, the connecting rod 42 will drive the rotating plate 43 to move in the discharge port 2. At this time, since the rotating plate 43 is rotatably connected, it will be rotated under force when it is inside the insertion side cavity 21, which will increase the unblocking effect in the discharge port 2.
[0036] Example 2
[0037] like Figure 1-5 As shown, a plastic powder fine sieve grinding device has a through cavity 22 that extends longitudinally through the bottom of the discharge port 2, and a side cavity 21 that extends laterally through both ends of the discharge port 2. The side cavity 21 and the through cavity 22 are connected and are used to send unqualified plastic powder to a plastic particle coarse grinding device for further grinding. The rotating blade 43 moves within the side cavity 21 to clear the blockage.
[0038] The side cavity 21 and the rotating plate 43 are connected. The side cavity 21, the through cavity 22 and the screen plate 1 are connected to each other, which facilitates material discharge and unblocking operations.
[0039] A conical screen 11 is connected inside the sieve plate 1. The conical screen 11 is designed in a conical shape. During sieving, unqualified materials will be discharged through the side cavity 21 and the through cavity 22. A discharge hopper 5 is set at the bottom of the sieve plate 1. The discharge hopper 5 is used to process qualified plastic powder. Several vibrating components 6 are connected between the discharge hopper 5 and the sieve plate 1. When in use, a vibration motor is installed on the outside of the sieve plate 1. The vibrating components 6 are used to vibrate the sieve plate 1. The vibrating components 6 have dampers inside to assist the sieve plate 1 in cooperating with the vibration motor to perform the vibrating sieving operation.
[0040] The effect achieved by the entire embodiment 2 is that the conical screen 11 is designed in a conical shape. During screening, unqualified materials will be discharged through the side cavity 21 and the through cavity 22. The discharge bucket 5 is used to discharge qualified plastic powder. When in use, a vibration motor is installed on the outside of the screen plate 1. The vibrating component 6 performs the screening operation on the screen plate 1. The vibrating component 6 has a damper to assist the screen plate 1 in cooperating with the vibration motor to perform the screening operation. The side cavity 21 and the through cavity 22 are connected to discharge unqualified plastic powder to the plastic particle coarse grinding device for further grinding. The rotating plate 43 moves in the side cavity 21 to perform the unblocking operation.
[0041] Working principle: When using this plastic powder fine sieve grinding device, an external power supply is connected. First, the powder passes through sieve plate 1 as shown in the diagram. Figure 1 As shown in the circular shell, it is used to hold plastic powder transferred by the plastic coarse abrasive conveyor. The upright sieve plate 1 is used to prevent the plastic powder from falling off during shaking and sieving. The discharge port 2 is connected to the sieve plate 1, and is used to re-enter the plastic coarse abrasive conveyor to transport unqualified plastic powder to the plastic granule coarse grinding device for further grinding. When discharging in the discharge port 2, the rotating blade 43 will abut against the side of the limiting member 3. At this time, the push plate 41 is located at the position furthest away from the limiting member 3. When the discharge port 2 is blocked, the push plate 41 is pushed. At this time, the push plate 41 is like... Figure 2 As shown, it fits into the limiting part 3. At the same time, the connecting rod 42 will drive the rotating plate 43 to move in the discharge port 2. At this time, since the rotating plate 43 is rotatably connected, it will be rotated under force when it is inside the insertion side cavity 21, which will increase the unblocking effect in the discharge port 2.
[0042] Secondly, the conical screen 11 has a conical design. During screening, unqualified materials will be discharged through the side cavity 21 and the through cavity 22. The discharge bucket 5 is used to discharge qualified plastic powder. When in use, a vibration motor is installed on the outside of the screen plate 1. The vibrating component 6 performs the screening operation on the screen plate 1. The vibrating component 6 has a damper to assist the screen plate 1 in coordinating with the vibration motor to perform the screening operation. The side cavity 21 and the through cavity 22 are connected to discharge unqualified plastic powder to the plastic particle coarse grinding device for further grinding. The rotating plate 43 moves in the side cavity 21 to clear the blockage. Finally, the operation of the plastic powder fine screening and grinding device is completed.
