Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically a high-precision metal separator for plastic processing. Background Technology

[0002] The raw materials for plastic granules are not pure in the early stages. If there are impurities, especially metallic impurities, on the outer wall of the raw materials, in order to prevent the finished products from containing metallic impurities, it is necessary to separate the metallic impurities from the plastic granules in advance. Therefore, a special plastic granule to metal granule separator is required.

[0003] Most plastic pellet metal separators on the market simply fix a magnetic block inside to separate metal particles from the plastic pellets. However, the magnetic block is not fixed in place, resulting in low separation efficiency, and the metal separated by the magnetic block is difficult to remove quickly from the separator.

[0004] As disclosed in Chinese Patent CN209633527U, a plastic particle metal separator uses a turntable to drive a magnetic rod to rotate. When the plastic particles flow down from the feed inlet, they can make initial contact with the magnetic rod. The rotating magnetic rod can then contact the plastic particles that have fallen onto the filter screen, agitating the accumulated particles and quickly separating the metal particles from the plastic particles. After the magnetic rod has been separating for a period of time, a cylinder can push the magnetic rods one by one into the through holes, thus conveying the metal particles adhering to their outer walls out of the separation chamber and cleaning the separated metal particles.

[0005] After separation by the separation device, the magnetic rod along with the metal particles on its outer side needs to be removed from the separation box for cleaning. However, the metal particles adsorbed onto the magnetic rod are small, making it difficult to quickly remove them from the outer end of the magnetic rod.

[0006] Therefore, we urgently need to provide a high-precision metal separator for plastic processing that facilitates the removal of metal particles. Utility Model Content

[0007] The purpose of this invention is to provide a high-precision metal separator for plastic processing, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-precision metal separator for plastic processing, comprising a separation box and a support column for separating plastic particles for plastic processing, wherein the support column is fixedly connected to the four lower corners of the separation box, and separation mechanisms are connected to the inner and outer ends of the separation box.

[0009] The separation mechanism includes a coil frame fixedly connected to the upper right side and the lower left side of the separation chamber. An electromagnetic coil is wound around the outer end of the coil frame. Power supplies are installed on the left and right sides of the separation chamber. Adsorption plates are fixedly connected to the left and right sides of the separation chamber at the positions of the outer ends of the electromagnetic coils. A connecting frame is fixedly connected to the lower right side of the separation chamber. A receiving box is slidably connected to the lower inner side of the connecting frame. A handle is fixedly connected to the lower right side of the receiving box. A sealing plate is fixedly connected to the upper right side of the receiving box. A connecting frame is fixedly connected to the middle position of the upper right side of the connecting frame. A spring is fixedly connected to the top inner side of the connecting frame. A fixing ring is fixedly connected to the lower end of the spring. A pull rod is fixedly connected to the inner side of the fixing ring. A feeding unit is provided at the upper end of the separation chamber.

[0010] A further improvement is that the feeding unit includes a feeding frame fixedly connected to the middle position of the upper side of the separation box, a circular frame fixedly connected to the upper end of the feeding frame, a feeding hopper fixedly connected to the upper end of the circular frame, a motor installed on the rear side of the circular frame, and a transmission roller fixedly connected to the front end of the output shaft of the motor.

[0011] A further improvement is that the bottom of the separation box is an inclined surface, with the left side higher than the right side. The right end of the separation box is located at the right end of the inclined surface, and the upper left end of the receiving box is located at the right end of the inclined surface. As a result, the plastic particles falling to the bottom of the separation box will slide to the right along the inclined bottom surface until they slide to the discharge port and fall into the receiving box inside the right end connecting frame.

[0012] A further improvement is that a sliding hole is provided at the middle position of the upper part of the connecting bracket and the connecting bracket at the upper part of the connecting frame. The outer side of the pull rod is slidably connected to the inner side of the sliding hole, so that when the spring moves and drives the fixed ring to move, the pull rod will slide along the inner side of the sliding hole.

[0013] A further improvement is that the outer side of the sealing plate is slidably connected to the upper right side of the inner side of the connecting frame. An insertion hole is provided in the middle of the upper part of the sealing plate. The lower outer side of the pull rod is inserted into the inner side of the insertion hole. Thus, when the spring pushes down the fixing ring, the pull rod moves down to the insertion hole at the upper part of the sealing plate, which can fix the receiving box and the handle to the connecting frame.

[0014] A further improvement is that the adsorption plate is made of iron, so that when the electromagnetic coil at the outer end of the coil frame is energized and generates magnetism, the conductive adsorption plate will also generate a certain amount of magnetism.

[0015] A further improvement is that the outer end of the conveyor roller has a feeding trough with an equal arc. The outer side of the conveyor roller is slidably connected to the inner side of the circular frame. The upper end of the circular frame has a receiving port located below the feeding hopper, and the lower end of the circular frame has a dropping port located above the discharging frame. The upper end of the separation box has a feeding port located below the discharging frame. Thus, after the plastic granules to be separated are poured into the feeding hopper, when the output shaft of the motor is started and the conveyor roller is rotated, the plastic granules in the feeding hopper will enter the feeding trough at the upper end of the conveyor roller from the receiving port at the bottom of the feeding hopper. Then, as the conveyor roller rotates, the feeding trough containing the plastic granules will also rotate downwards until it rotates to the dropping port at the lower end. The plastic granules in the feeding trough fall into the discharging frame and then fall into the interior of the separation box from the feeding port.

[0016] In summary, this application discloses a high-precision metal separator for plastic processing.

[0017] In this technical solution, when the metal separator separates metal particles, the separated metal particles are adsorbed onto the outside of the adsorption plate at the outer end of the electromagnetic coil. When it is necessary to clean the metal particles, simply empty the collection box and turn off the power to the outer end of the electromagnetic coil, so that the electromagnetic coil no longer generates magnetism. The metal particles at the outer end of the adsorption plate will no longer be adsorbed and will all fall to the bottom and slide to the right into the collection box for collection. Then, the collection box can be pulled out to complete the cleaning of the metal particles, thus making the cleaning of metal particles in the metal separator very convenient.

[0018] Furthermore, after the plastic granules to be separated are poured into the feed hopper, the output shaft of the motor is started to rotate, causing the transmission roller to rotate. The plastic granules in the feed hopper will enter the feeding trough at the upper end of the transmission roller from the receiving port at the bottom of the feed hopper. Then, as the transmission roller rotates, the feeding trough containing plastic granules will also rotate downwards until it reaches the discharge port at the bottom. The plastic granules in the feeding trough will fall into the discharge frame and then fall into the interior of the separation box from the feed port. This allows the plastic granules in the feed hopper to be quantitatively and continuously conveyed into the separation box, avoiding a large number of plastic granules directly entering the separation box, which would prevent the metal particles in the box from being attracted to the outer end of the adsorption plate by the electromagnetic coil in time.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a high-precision metal separator for plastic processing, including a separation box 1 for separating plastic particles for plastic processing and a support column 2. The support column 2 is fixedly connected to the four lower corners of the separation box 1, and the inner and outer ends of the separation box 1 are connected to a separation mechanism.

[0027] The separation mechanism includes a coil frame 301 fixedly connected to the upper right end of the inner side of the separation box 1 and the lower left end of the inner side of the separation box 1. An electromagnetic coil 302 is wound around the outer end of the coil frame 301. Power supplies 303 are installed on the left and right sides of the separation box 1. Adsorption plates 304 are fixedly connected to the left and right ends of the inner side of the separation box 1 at the position of the outer end of the electromagnetic coil 302. The adsorption plates 304 are iron plates. When the electromagnetic coil 302 at the outer end of the coil frame 301 is energized and generates magnetism, the conductive adsorption plates 304 will also generate a certain magnetism, making it easier to adsorb metal particles in plastic particles.

[0028] A connecting frame 305 is fixedly connected to the lower right side of the separating box 1. A receiving box 306 is slidably connected to the lower inner side of the connecting frame 305. The bottom of the interior of the separating box 1 is an inclined surface, with the left side higher than the right side. A discharge port is opened at the right end of the right side of the inclined surface. The upper left end of the receiving box 306 is located at the right end of the inclined surface. Thus, the plastic particles falling to the bottom of the interior of the separating box 1 will slide to the right along the inclined bottom surface until they slide to the discharge port and fall into the receiving box 306 inside the connecting frame 305 on the right side.

[0029] A handle 307 is fixedly connected to the lower right side of the receiving box 306, and a sealing plate 308 is fixedly connected to the upper right side of the receiving box 306. A connecting frame 309 is fixedly connected to the middle position of the upper right side of the connecting frame 305. A spring 310 is fixedly connected to the top inner side of the connecting frame 309, and a fixing ring 311 is fixedly connected to the lower end of the spring 310. A pull rod 312 is fixedly connected to the inner side of the fixing ring 311. A sliding hole is provided at the middle position of the upper inner side of the connecting frame 309 and at the upper inner side of the connecting frame 305. The outer side of the pull rod 312 is slidably connected to the inner side of the sliding hole. When the spring 310 bounces and drives the fixing ring 311 to move, it will drive the pull rod 312 to slide along the inner side of the sliding hole, thereby limiting the movement trajectory of the pull rod 312.

[0030] The outer side of the sealing plate 308 is slidably connected to the upper right side of the inner side of the connecting frame 305. An insertion hole is provided in the middle of the upper part of the inner side of the sealing plate 308. The lower outer side of the pull rod 312 is inserted into the inner side of the insertion hole. Thus, after the receiving box 306 is slid to the inner side of the connecting frame 305, the sealing plate 308 will slide to the upper right side of the connecting frame 305. Then, the spring 310 pushes the fixing ring 311 back, so that the pull rod 312 moves down to its lower end and is inserted into the insertion hole at the upper end of the sealing plate 308. This fixes the receiving box 306 and the handle 307 into the connecting frame 305, keeping the right side of the connecting frame 305 closed.

[0031] A feeding unit is provided at the upper end of the separation box 1. The feeding unit includes a feeding frame 401 fixedly connected to the middle position of the upper side of the separation box 1. A circular frame 402 is fixedly connected to the upper end of the feeding frame 401. A feeding hopper 403 is fixedly connected to the upper end of the circular frame 402. A motor 404 is installed on the rear side of the circular frame 402. A transmission roller 405 is fixedly connected to the front end of the output shaft of the motor 404.

[0032] The outer end of the conveyor roller 405 has a feeding groove with an equal arc. The outer side of the conveyor roller 405 is slidably connected to the inner side of the circular frame 402. The upper end of the circular frame 402 is provided with a receiving port below the feeding hopper 403, and the lower end of the circular frame 402 is provided with a dropping port above the discharging frame 401. The upper end of the separation box 1 is provided with a feeding port below the discharging frame 401. Thus, after the plastic granules to be separated are poured into the feeding hopper 403, when the output shaft of the motor 404 is started and the conveyor roller 405 is rotated, the plastic granules in the feeding hopper 403 will be discharged from the bottom of the feeding hopper 403. The material enters the feeding trough at the upper end of the transmission roller 405 through the receiving port. Then, as the transmission roller 405 rotates, the feeding trough containing plastic particles also rotates downwards until it reaches the discharge port at the lower end. The plastic particles in the feeding trough fall into the discharge frame 401 and then fall from the inlet into the interior of the separation box 1. This allows the plastic particles in the feeding hopper 403 to be quantitatively and continuously conveyed into the separation box 1, avoiding a large number of plastic particles from directly entering the separation box 1, which would prevent the metal particles from being magnetically attracted to the outer end of the adsorption plate 304 in time by the electromagnetic coil 302.

[0033] Working Principle: When separating metal particles mixed in plastic granules used for plastic processing, the plastic granules to be separated are first poured into the feed hopper 403. Then, the power supply 303 is turned on, energizing the electromagnetic coil 302 to generate magnetism. Next, the motor 404 is started, and its output shaft rotates, driving the front-end transmission roller 405, located inside the circular frame 402, to rotate. The plastic granules in the feed hopper 403 are continuously fed into the separation chamber 1 through the rotating feed chute. The plastic granules entering the separation chamber 1 fall onto the adsorption plate 304 and slide down its outer side. Simultaneously, the metal particles are attracted to the surface of the adsorption plate 304 by the magnetic electromagnetic coil 302. The particles fall directly to the bottom of the separation box 1, then slide to the right into the collection box 306 in the connecting frame 305 to be collected. After the plastic particles in the feed hopper 403 are separated, pull up the lever 312 to move its lower end out of the insertion hole at the top of the sealing plate 308. Then pull the handle 307 to the right to pull out the collection box 306 and take out the plastic particles in the collection box 306. Then put the collection box 306 back into the connecting frame 305 and turn off the power 303. At this time, the electromagnetic coil 302 no longer generates magnetism, and the metal particles at the outer end of the adsorption plate 304 are no longer adsorbed. They all fall to the bottom and slide to the right into the collection box 306 to be collected. Then pull out the collection box 306 to clean the metal particles.
