Description

Technical Field

[0001] This invention relates to the field of plastic processing technology, specifically to a plastic granule impurity removal device for plastic processing. Background Technology

[0002] Plastics are mainly composed of carbon, oxygen, hydrogen, nitrogen, and other organic or inorganic elements. The finished product is a solid, but during the manufacturing process, it is a molten liquid. Therefore, it can be melted by heating, made to flow by applying pressure, and made to solidify by cooling, thus forming various shapes. This vast and diverse group of materials is called plastics.

[0003] In existing technologies, plastic granules are often used as raw materials during plastic processing. After screening and impurity removal, the granules are processed using equipment. However, plastic granules often contain numerous small and magnetic impurities. Magnetic impurities are separated by placing an electromagnetic plate near the granules or on an electromagnetic plate, allowing the plate to adsorb the magnetic impurities. Smaller impurities are then separated by a sieve. This separation method is cumbersome and cannot provide continuous adsorption. When there are many magnetic impurities on the electromagnetic plate, the adsorption force on the magnetic impurities within the plastic granules weakens, necessitating stopping the separation to clean the magnetic impurities from the electromagnetic plate, thus affecting the impurity removal efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a plastic particle impurity removal device for plastic processing, so as to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A plastic granule impurity removal device for plastic processing includes an impurity removal box and a support frame. The impurity removal box is mounted on the support frame. A dividing plate is provided inside the impurity removal box, dividing it into a discharge chamber and a separation chamber. A cleaning component is provided inside the discharge chamber, and a lower screen plate is provided at the bottom port of the separation chamber. A central hole is provided in the middle of the dividing plate, and a supporting rotating shaft is installed in the central hole for rotatable engagement. The lower end of the supporting rotating shaft is connected to the output end of a rotary motor mounted on the support frame. A fixing sleeve is fixed to the top of the supporting rotating shaft, and at least two magnetic adsorption mechanisms are provided on the outer wall of the fixing sleeve. Each magnetic adsorption mechanism includes a crossbar, a mounting shaft, and multiple electromagnetic adsorption components. One end of the crossbar... Fixed to the side wall of the fixed sleeve, the mounting rod shaft is elastically rotated on the crossbar by a spring. Multiple electromagnetic adsorption components are evenly distributed along the axis of the mounting rod shaft, and the top of the electromagnetic adsorption components is connected to the mounting rod shaft. The electromagnetic adsorption components are in a vertical state in their original state. The end of the mounting rod shaft away from the fixed sleeve has a protrusion with a swing gear on it. The inner wall of the separation chamber has multiple rack modules that can mesh with the swing gears. When the swing gear passes the rack modules, it can rotate alternately in both directions. Both ends of the dividing plate are provided with clearance racks. When the swing gear passes the clearance racks, it can mesh with the clearance racks. The clearance racks drive the mounting rod shaft to rotate and make the electromagnetic adsorption components rotate to a horizontal state.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0008] In one alternative embodiment: the gear module includes an arc-shaped front rack and an arc-shaped rear rack, which are arranged opposite to and staggered. When the swing gear rotates around the axis of the supporting rotating rod as the crossbar rotates, it passes between the arc-shaped front rack and the arc-shaped rear rack. When the swing gear disengages from the arc-shaped front rack, it engages with the arc-shaped rear rack.

[0009] In one alternative: the side portion of the avoidance rack is further provided with an arc-shaped limiting strip, and the end of the protrusion has a locking slot. When the swing gear disengages from the avoidance rack, the locking slot slides onto the arc-shaped limiting strip.

[0010] In one alternative embodiment: the electromagnetic adsorption component includes an upper connecting rod, a cylindrical electromagnetic housing, and a fixing seat. The fixing seat is fixedly sleeved on the mounting rod shaft. The top of the upper connecting rod is located on the fixing seat. The cylindrical electromagnetic housing is located outside the upper connecting rod and has an electromagnetic rod inside that can switch on and off the power. The diameter of the cylindrical electromagnetic housing gradually decreases from top to bottom.

[0011] In one alternative: the inner wall of the descrambling chamber has a wavy protrusion and the upper connecting rod is rotatably engaged with the fixed seat. The top of the upper connecting rod has a driven gear. The magnetic adsorption mechanism also includes a horizontal rack and a top roller. The horizontal rack is located on the horizontal rod and can slide along the length of the horizontal rack on the supporting rotating rod shaft. When the electromagnetic adsorption component is in a vertical state, each driven gear meshes with the horizontal rack. One end of the horizontal rack is connected to the fixed sleeve through a return spring. The top roller is located at the end of the horizontal rack away from the fixed sleeve. The top roller is opposite to the protrusion and can abut against the protrusion when it is inside the separation chamber.

[0012] In one alternative: the top roller includes a top frame and a roller body, the top frame is fixedly connected to the end of the transverse rack, the roller body is rotatably mounted on the top frame and the roller body contacts the protrusion in a rolling friction manner.

[0013] In one alternative: the cleaning component includes a bracket and a plurality of cleaning rods, the bracket is located inside the cleaning chamber and the end of the bracket is connected to the inner wall of the cleaning chamber, and the cleaning rods are arranged in an arc shape inside the cleaning chamber and are provided with bristles.

[0014] In one alternative: the lower screen plate has a connecting part at one edge, and the connecting part is rotatably connected to the side frame on the outer wall of the impurity removal box via a flipping rod shaft. The side wall of the impurity removal box also has a flipping assembly, which includes a flipping screw, a flipping motor, and a flipping rack. The flipping screw is rotatably mounted on the side frame, and the output end of the flipping motor is connected to the flipping screw. The flipping screw has a spiral seat that slides longitudinally on the side wall of the impurity removal box. The top of the flipping rack is fixedly connected to the spiral seat. The flipping rod shaft has a flipping gear, and the flipping gear meshes with the flipping rack.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this invention, the electromagnetic adsorption component can be inserted vertically into the plastic granules, thereby better adsorbing magnetic impurities. Furthermore, the rotation and movement of the electromagnetic adsorption component inside the plastic granules can effectively agitate the plastic granules, making it easier for smaller impurities to pass through the lower screen plate.

[0017] 2. In this invention, the electromagnetic adsorption component can pass through the dividing plate in a horizontal state by using the oscillating gear and the avoidance rack, thus avoiding interference. The electromagnetic adsorption component is in a vertical state in the descrambling chamber and the magnetic impurities on it are completely cleaned by the cleaning component and the power-off method.

[0018] 3. When separating magnetic impurities, the present invention can agitate the plastic particles to avoid clogging of the lower screen plate, which facilitates the separation of smaller impurities. Moreover, the magnetic impurities are completely separated, making it highly practical. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0027] In one embodiment, such as Figures 1-4 As shown, a plastic granule impurity removal device for plastic processing includes an impurity removal box 100 and a support frame 200. The impurity removal box 100 is mounted on the support frame 200. A dividing plate 110 is provided inside the impurity removal box 100, dividing it into a discharge chamber 120 and a separation chamber 130. The discharge chamber 120 has a cleaning component inside, and the bottom port of the separation chamber 130 has a lower screen plate 400. The dividing plate 110 has a central hole in its middle. A supporting rotating rod shaft 310 is installed in the central hole 111 and rotates therewith. The lower end of the supporting rotating rod shaft 310 is connected to the output end of a rotary motor 300 mounted on the support frame 200. A fixing sleeve 700 is fixed to the top of the supporting rotating rod shaft 310, and at least two magnetic adsorption mechanisms 600 are provided on the outer wall of the fixing sleeve 700. The magnetic adsorption mechanism 600 includes a crossbar 610, a mounting rod shaft 620, and multiple electromagnetic adsorption components 640. One end of component 610 is fixed to the side wall of the fixing sleeve 700. The mounting rod shaft 620 is elastically rotatable on the crossbar component 610 via a spring. Multiple electromagnetic adsorption components 640 are evenly distributed along the axis of the mounting rod shaft 620, and the top of each electromagnetic adsorption component 640 is connected to the mounting rod shaft 620. The electromagnetic adsorption components 640 are in a vertical position in their original state. The end of the mounting rod shaft 620 away from the fixing sleeve 700 has a protrusion 621, and the protrusion 621 has a swing gear 622. The inner wall of the separation chamber 130 has multiple rack modules, which can mesh with the swing gear 622. When the swing gear 622 passes through the rack module, the swing gear 622 can rotate alternately in both directions. Both ends of the dividing plate 110 are provided with clearance racks 800. When the swing gear 622 passes through the clearance racks 800, it can mesh with the clearance racks 800. The clearance racks 800 drive the mounting rod shaft 620 to rotate and cause the electromagnetic adsorption component 640 to rotate to a horizontal state.

[0028] In this embodiment of the invention, plastic particles and impurities are placed inside the separation chamber 130; smaller impurities can fall through the lower screen plate 400 and be removed; the rotary motor 300 drives the supporting rotating rod shaft 310 to rotate around the center of the impurity removal box 100, thereby causing the magnetic adsorption mechanism 600 to alternately rotate into the discharge chamber 120 and the separation chamber 130; when the magnetic adsorption mechanism 600 is about to rotate into the discharge chamber 120 or the separation chamber 130, the oscillating gear 622 begins to mesh with the avoidance rack 800, and with the magnetic adsorption... The movement of mechanism 600 causes the oscillating gear 622 and mounting rod shaft 620 to rotate, driving the electromagnetic adsorption component 640 to rotate to a horizontal position. This allows the electromagnetic adsorption component 640 to pass horizontally over the dividing plate 110 without interference. When the magnetic adsorption mechanism 600 is above the separation chamber 130, the electromagnetic adsorption component 640 is in its original vertical position, allowing its lower end to insert into the plastic granules. As the electromagnetic adsorption component 640 rotates around the supporting rotating rod shaft 310, it can... The system agitates the plastic granules and allows smaller impurities to pass quickly through the 400-mesh screen of the lower screen plate, preventing blockage. When the electromagnetic adsorption component 640 is inserted into the plastic granules, it becomes magnetic due to energization, attracting magnetic impurities (such as iron particles) within the granules. This effectively cleans the plastic granules of magnetic and smaller impurities. When the oscillating gear 622 rotates with the crossbar 610 to the rack module, the rack module uses the rotation of the crossbar 610 as power to oscillate in coordination with the gear. The meshing of gear 622 causes the mounting rod shaft 620 to rotate alternately in both directions. The mounting rod shaft 620 drives the electromagnetic adsorption component 640 to swing, thereby enabling the electromagnetic adsorption component 640 to better adsorb magnetic impurities and agitate plastic particles. When the magnetic adsorption mechanism 600 rotates to the upper side of the discharge chamber 120, the electromagnetic adsorption component 640 is de-energized, and the magnetic impurities adsorbed on its side wall fall off. Furthermore, when the electromagnetic adsorption component 640 passes through the cleaning component, the cleaning component can sweep away the magnetic impurities adsorbed on the outer wall of the electromagnetic adsorption component 640, thus facilitating the subsequent adsorption of magnetic impurities.

[0029] In one embodiment, such as Figure 3 and Figure 4As shown, the gear module includes an arc-shaped front rack 820 and an arc-shaped rear rack 830. The arc-shaped front rack 820 and the arc-shaped rear rack 830 are arranged opposite to each other and offset. When the swing gear 622 rotates with the crossbar 610 around the supporting rotating rod shaft 310, it passes between the arc-shaped front rack 820 and the arc-shaped rear rack 830. When the swing gear 622 disengages from the arc-shaped front rack 820, it engages with the arc-shaped rear rack 830. In this embodiment of the invention, when the magnetic adsorption mechanism 600 rotates to the gear module, the swing gear 622 begins to engage with the arc-shaped front rack 820, causing the mounting rod shaft 620 to rotate in one direction. When the swing gear 622 disengages from the arc-shaped front rack 820, it engages with the arc-shaped rear rack 830, thus causing the mounting rod shaft 620 to rotate in the opposite direction, thereby realizing the swing of the electromagnetic adsorption component 640.

[0030] In one embodiment, such as Figure 3 and Figure 4 As shown, the side portion of the avoidance rack 800 is also provided with an arc-shaped limiting strip 810, and the end of the protrusion 621 has a latch 623. When the swing gear 622 disengages from the avoidance rack 800, the latch 623 slides onto the arc-shaped limiting strip 810. In this embodiment of the invention, the engagement of the swing gear 622 and the avoidance rack 800 is driven by the rotation of the magnetic adsorption mechanism 600 around the support rotating rod shaft 310. The horizontal rod 610 rotates, causing the electromagnetic adsorption component 640 to be in a horizontal state. When the electromagnetic adsorption component 640 is in a horizontal state, the swing gear 622 disengages from the avoidance rack 800, and the latch 623 just locks onto the arc-shaped limiting strip 810. The arc-shaped limiting strip 810 can restrict the rotation of the protrusion 621 and the mounting rod shaft 620, thereby keeping the electromagnetic adsorption component 640 in a horizontal state as it passes through the dividing plate 110.

[0031] In one embodiment, such as Figures 2-4 As shown, the electromagnetic adsorption component 640 includes an upper connecting rod 641, a cylindrical electromagnetic housing 642, and a fixing base 643. The fixing base 643 is fixedly sleeved on the mounting rod shaft 620. The top of the upper connecting rod 641 is disposed on the fixing base 643. The cylindrical electromagnetic housing 642 is disposed outside the upper connecting rod 641, and the cylindrical electromagnetic housing 642 has an electromagnetic rod that can be energized and de-energized inside. The diameter of the cylindrical electromagnetic housing 642 gradually decreases from top to bottom. In this embodiment of the invention, the electromagnetic rod becomes magnetic when energized and adsorbs magnetic impurities through the outer wall of the cylindrical electromagnetic housing 642. The gradually decreasing diameter of the cylindrical electromagnetic housing 642 from top to bottom increases the adsorption surface of the magnetic impurities.

[0032] In one embodiment, such as Figures 2-4As shown, the inner wall of the unloading chamber 120 has a wavy protrusion 180, and the upper connecting rod 641 is rotatably engaged with the fixed seat 643. The top of the upper connecting rod 641 has a driven gear 650. The magnetic adsorption mechanism 600 also includes a horizontal rack 630 and a top roller. The horizontal rack 630 is disposed on the horizontal rod 610 and can slide along the length of the horizontal rack 630 on the supporting rotating rod shaft 310. When the electromagnetic adsorption component 640 is in a vertical state, each driven gear 650 meshes with the horizontal rack 630. One end of the horizontal rack 630 is connected to the fixed sleeve 700 through a return spring 660. The top roller is disposed on the horizontal rack 630 away from the fixed sleeve 700. At the end, the top roller is opposite to the protrusion 180, and the top roller can abut against the protrusion 180 when it is inside the separation chamber 130. In this embodiment of the invention, when the magnetic adsorption mechanism 600 rotates to the upper side of the descrambling chamber 120, the electromagnetic adsorption member 640 is in a vertical state, and the top roller begins to contact the protrusion 180. Due to the wavy shape of the protrusion 180, the top roller can cooperate with the return spring 660 to drive the horizontal rack 630 to reciprocate on the horizontal bar 610. Due to the meshing of the horizontal rack 630 and the driven gear 650, multiple electromagnetic adsorption members 640 rotate, so that the electromagnetic adsorption members 640 can throw off the magnetic impurities on the outer wall and cooperate with the cleaning member to completely clean the magnetic impurities on the outer wall of the electromagnetic adsorption members 640.

[0033] In one embodiment, such as Figure 2 and Figure 4 As shown, the top roller includes a top frame 680 and a roller body 670. The top frame 680 is fixedly connected to the end of the transverse rack 630. The roller body 670 is rotatably mounted on the top frame 680 and the roller body 670 contacts the protrusion 180 in a rolling friction manner.

[0034] In one embodiment, such as Figure 2 As shown, the cleaning component includes a bracket 150 and multiple cleaning rods 160. The bracket 150 is located inside the impurity removal box 100 and its end is connected to the inner wall of the impurity removal box 100. The cleaning rods 160 are arranged in an arc shape inside the impurity removal box 100 and are provided with bristles 170. In this embodiment of the invention, when the electromagnetic adsorption component 640 in a vertical state passes between two cleaning rods 160, the bristles 170 can dislodge magnetic impurities on the outer wall of the flipping rack 540. The bottom side wall of the discharge chamber 120 has a slag discharge port 140 for discharging impurities.

[0035] In one embodiment, such as Figure 1 and Figure 6As shown, the lower screen plate 400 has a connecting part 410 at one edge, and the connecting part 410 is rotatably connected to the side frame 520 provided on the outer wall of the impurity removal box 100 via a flipping rod shaft 560. The side wall of the impurity removal box 100 also has a flipping assembly 500, which includes a flipping screw 510, a flipping motor 530, and a flipping rack 540. The flipping screw 510 is rotatably mounted on the side frame 520, and the output end of the flipping motor 530 is connected to the flipping screw 510. The flipping screw 510 has a spiral seat 570 that slides longitudinally on the side wall of the impurity removal box 100, and the flipping rack 540... The top of the screw 570 is fixedly connected to the screw seat 570. The rotating rod shaft 560 has a rotating gear 550 and the rotating gear 550 meshes with the rotating rack 540. In this embodiment of the invention, the rotating motor 530 drives the rotating screw 510 to rotate and causes the screw seat 570 to move axially on the rotating screw 510. The rotating rack 540 moves with the screw seat 570 and rotates the rotating rod shaft 560 through meshing with the rotating gear 550. This causes the connecting part 410 and the lower screen plate 400 to rotate. After the impurity removal is completed, the lower screen plate 400 rotates downward and opens the bottom of the separation chamber 130, which facilitates the discharge of plastic particles.

[0036] In the above embodiment, the rotary motor 300 drives the supporting rotating rod shaft 310 to rotate around the center of the impurity removal box 100, thereby causing the magnetic adsorption mechanism 600 to alternately rotate into the desizing chamber 120 and the separation chamber 130. When the magnetic adsorption mechanism 600 is about to rotate into the desizing chamber 120 or the separation chamber 130, the oscillating gear 622 begins to mesh with the avoidance rack 800. As the magnetic adsorption mechanism 600 moves, the oscillating gear 622 and the mounting rod shaft 620 rotate, driving the electromagnetic adsorption... When component 640 rotates to a horizontal position, the electromagnetic adsorption component 640 passes horizontally through the dividing plate 110 without interfering with it. When the magnetic adsorption mechanism 600 is above the separation chamber 130, the electromagnetic adsorption component 640 is in its original vertical position, allowing its lower end to insert into the plastic granules. As the electromagnetic adsorption component 640 rotates around the supporting rotating rod axis 310, it agitates the plastic granules and allows smaller impurities to quickly pass through the sieve holes of the lower screen plate 400, preventing blockage. When inserted into the plastic granules, the electromagnetic adsorption component 640 is energized and becomes magnetic, adsorbing magnetic impurities (such as iron particles) inside the plastic granules. This effectively cleans magnetic and smaller impurities from the plastic granules. When the swing gear 622 rotates with the crossbar 610 to the rack module, the rack module uses the rotation of the crossbar 610 as power and engages with the swing gear 622 to ensure proper positioning. The mounting shaft 620 rotates alternately in both directions, driving the electromagnetic adsorption component 640 to swing, thus enabling the electromagnetic adsorption component 640 to better adsorb magnetic impurities and agitate plastic particles. When the magnetic adsorption mechanism 600 rotates to the upper side of the discharge chamber 120, the electromagnetic adsorption component 640 is de-energized, and the magnetic impurities adsorbed on its side wall fall off. Furthermore, when the electromagnetic adsorption component 640 passes through the cleaning component, the cleaning component can clean off the magnetic impurities adsorbed on the outer wall of the electromagnetic adsorption component 640, thereby facilitating the subsequent adsorption of magnetic impurities.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
