Description

Technical Field

[0001] The utility model relates to the technical field of separators, in particular to a plastic particle metal separator. Background Art

[0002] When the equipment used for injection molding is in use, the plastic granule raw materials will first be poured into the lower hopper, the plastic granule raw materials will then enter the injection molding component to be heated and melted, and injected into the corresponding mold cavity, and finally injection molded into a plastic product.

[0003] Since the quality of plastic pellets varies greatly in the early stage, and the shape of plastic pellets is roughly similar to that of rice grains, if there are impurities, especially metal impurities, on the outer wall of plastic pellets, during the heating and melting process, the melting point of metal impurities is much higher than that of plastic pellets, which will cause impurity spots on the final injection molded plastic products, affecting the final molding quality of the injection molded products. Therefore, it is urgent to use a plastic pellet metal separator to separate them.

[0004] However, the separation effect of the plastic particle metal separators currently on the market is still not ideal, and they are unable to separate non-magnetic metal particles, resulting in the final product still containing metal particles, which still affects subsequent products and urgently needs to be improved.

Since the metal particles are heavier, they will remain inside the conical groove. The plastic particles will be blown to the outside of the fixed block and fall from the discharge funnel, completing the separation of plastic particles and non-magnetic metal particles, and further improving the separation effect.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0035] See also Figure 1-Figure 10A plastic particle metal separator comprises an outer shell 1, a rotating shaft 2 penetrating into the inner part of the outer shell 1 is arranged at the top center of the outer shell 1, and a first rotating drum 3 is connected to the bottom of the rotating shaft 2, a guide plate 4 is fixed to the bottom of the first rotating drum 3, and a second rotating drum 5 is fixed to the bottom of the guide plate 4, and a bearing plate 6 is rotatably connected to the outside of the second rotating drum 5 through a bearing, and the outer side of the bearing plate 6 is fixed to the inner side wall of the outer shell 1, and the bearing plate 6 can be used to support the second rotating drum 5 as a whole, so that the entire second rotating drum 5, the guide plate 4 and the first rotating drum 3 are more stable and convenient for subsequent use; a first screening component 11 is arranged on the outside of the first rotating drum 3, and a second screening component 12 is arranged on the outside of the second rotating drum 5;

[0036] A first gear 7 located at the top of the outer shell 1 is sleeved on the rotating shaft 2, a motor 9 is installed on the top of the outer shell 1, and the output end of the motor 9 is connected to a second gear 8 meshing with the first gear 7;

[0037] A feeding opening 10 is provided at the top of the outer shell 1;

[0038] The first screening assembly 11 and the second screening assembly 12 both include an inclined sector plate 21, and the inclined sector plate 21 both have a first screening area 211 and a second screening area 212, and the first screening area 211 is provided with an electromagnet 22; the end of the inclined sector plate 21 in the first screening assembly 11 is fixed to the outer wall of the first rotating drum 3, and the end of the inclined sector plate 21 in the second screening assembly 12 is fixed to the outer wall of the second rotating drum 5;

[0039] When in use, after starting the motor 9, the motor 9 can drive the second gear 8 to rotate. Since the second gear 8 is meshed with the first gear 7, the first gear 7 can drive the rotating shaft 2 and the first drum 3, the guide plate 4 and the second drum 5 to rotate. When the first drum 3 and the second drum 5 rotate, the first screening component 11 and the second screening component 12 both rotate. Since the first screening component 11 and the second screening component 12 both include an inclined sector plate 21, each of which is provided with an electromagnet 22, therefore, according to Figure 6 It can be seen that when the first rotating drum 3 drives the inclined sector plate 21 to rotate, due to the inclined setting of the inclined sector plate 21, after the material enters the outer shell 1 from the discharge hole 25, it will be received by the second screening area 212 on the inclined sector plate 21. As the inclined sector plate 21 continues to rotate, the material generates centrifugal force. Since the heavier the object, the greater the centrifugal force, the weight of the metal particles is greater than the weight of the plastic particles, making it easier for the metal particles to move toward the first screening area 211. At this time, the electromagnet 22 on the first screening area 211 will adsorb the metal particles to facilitate the separation of the metal particles from the plastic particles. Similarly, the second screening component 12 can be used for further screening and separation, so that plastic and metal can be more easily separated, and the use effect is better.

[0040] In order to allow the plastic particles in the first screening component 11 to fall onto the second screening component 12 for further screening and separation, a plurality of holes 13 are provided at equal intervals on the outer side walls of the first drum 3 and the second drum 5. At the same time, in order to prevent the holes 13 from opening during the screening process, a blocking component 14 for blocking the holes 13 is provided inside the first drum 3 and the second drum 5. A discharge hole 25 is provided at the bottom of the first drum 3. When in use, the blocking component 14 is used to open the hole 13, so that the plastic particles on the first screening component 11 will enter the first drum 3 through the hole 13 on the first drum 3, and then fall onto the second screening component 12 through the discharge hole 25 at the bottom of the first drum 3, so that the second screening component 12 can further screen and separate the plastic particles. The metal particles originally adsorbed by the electromagnet 22 on the first screening component 11 will always be adsorbed by the electromagnet 22 and will not fall again, thereby completing the separation of metal particles from plastic particles.

[0041] Furthermore, the blocking assembly 14 includes a blocking plate 141 corresponding to the hole 13 one by one and a driving member 142 for driving the blocking plate 141 to move laterally.

[0042] Furthermore, the driving member 142 includes a connecting rod 1421 fixed between the blocking plate 141, and the end of the connecting rod 1421 is connected to a trapezoidal block 1422, a T-shaped slide groove 1423 is provided on the inclined surface of the trapezoidal block 1422, and a T-shaped slider 1424 is slidably connected inside the T-shaped slide groove 1423, a connecting block 1425 is fixed to the end of the T-shaped slider 1424, and a plug rod 1426 is fixed to the top of the connecting block 1425; the top of the plug rod 1426 located inside the second rotating cylinder 5 is fixed to the bottom of the connecting block 1425 inside the first rotating cylinder 3, and the top of the plug rod 1426 located inside the first rotating cylinder 3 passes through the first rotating cylinder 3 and the rotating shaft 2, and is connected to a handle 1427 located outside the rotating shaft 2;

[0043] When in use, the handle 1427 is used to move the insertion rod 1426 up and down, so that the connecting blocks 1425 inside the first rotating drum 3 and the second rotating drum 5 can be synchronously raised or lowered. When the connecting block 1425 rises, the T-shaped slider 1424 will rise. Since the T-shaped slider 1424 slides inside the T-shaped slide groove 1423, and the T-shaped slide groove 1423 is provided on the inclined surface of the trapezoidal block 1422, when the connecting block 1425 drives the T-shaped slider 1424 to rise, the trapezoidal block 1422 will move toward the connecting block 1425, and then the connecting rod 1421 drives the sealing plate 141 to move toward the connecting block 1425, and the sealing plate 141 will be separated from the hole 13, so that the hole 13 is opened to facilitate material unloading.

[0044] In order to facilitate the insertion rod 1426 to rise or fall more stably, a vertical slide groove 15 is provided inside the rotating shaft 2, and a vertical slider 16 is slidably provided inside the vertical slide groove 15, the vertical slider 16 is fixed to the insertion rod 1426, and a groove 17 is provided on the side of the vertical slider 16, a spring 18 is provided inside the groove 17, and a ball 19 extending to the outside of the groove 17 is connected to the end of the spring 18, and a groove 20 adapted to the ball 19 is provided inside the vertical slide groove 15; Figure 8 and Fig. 9 It can be seen that when the insertion rod 1426 moves up and down to a certain position, the card ball 19 will adapt to the card slot 20 so that the insertion rod 1426 can be positioned, and then the blocking plate 141 can better maintain a certain position, thereby facilitating subsequent material unloading and blocking, and achieving a better use effect.

[0045] Furthermore, a receiving plate 26 is fixed on the inner wall of the outer shell 1, a fixing box 23 is fixed on the inclined sector plate 21, and the bottom of the fixing box 23 is in contact with the top of the receiving plate 26. A battery 24 for powering the electromagnet 22 is arranged inside the fixing box 23. The fixing box 23 rotates along with the inclined sector plate 21, so that the battery 24 inside it can continuously energize the electromagnet 22 to facilitate the adsorption of metal particles. When all the plastic particles are discharged, the electromagnet is powered off, and the metal particles will be discharged at this time, so as to facilitate more efficient recycling and better practicality.

[0046] Furthermore, a discharge funnel 28 is provided at the bottom of the outer shell 1, and a fixed block 27 is fixed to the inner bottom end of the outer shell 1, a conical groove 29 is provided on the top of the fixed block 27, and a clearance hole 30 is provided on the inner side wall of the conical groove 29, and a blower 31 is installed inside the clearance hole 30; when in use, due to the presence of non-magnetic metal in the metal particles, it will fall with the plastic particles, and since the plastic particles will fall into the conical groove 29 in a unified and concentrated manner, the blower 31 can be used to blow up the plastic particles in the conical groove 29 at this time, because the metal particles are heavier, they will remain inside the conical groove 29, and the plastic particles will be blown to the outside of the fixed block 27 and fall from the discharge funnel 28, completing the separation of the plastic particles and the non-magnetic metal particles, and further improving the separation effect.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
