Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling, and in particular to a device for recycling waste from production of plastic products. Background Art

[0002] In the production process of PC board, the raw materials are first prepared, dried and dehumidified, melted and plasticized by the extruder, extruded and formed, cooled and shaped, and then pulled and cut, which will produce a lot of scraps and plastic waste. If the scraps and plastic waste of plastic products are directly discarded, it will cause a waste of resources and increase the processing cost of plastic products. Therefore, it is necessary to process and recycle them. Because the shapes of plastic waste are different, the plastic waste on the loading port of the feeding equipment is placed in a messy way. As the loading port slides to the feeding port of the crushing module, some long strips of plastic waste are easy to get stuck in the feeding port of the crushing module, which causes the feeding of the crushing module to be blocked, affecting the efficiency of plastic waste recycling.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0037] like Figures 1 to 14 As shown, a plastic product production waste recycling device of the present invention includes: a mounting frame 1; the mounting frame 1 includes: a bracket 11, a crushing module 2 installed on the bracket 11, and a feed hopper 12 installed on the top of the crushing module 2; the bracket 11 is composed of a square frame and an inclined frame installed on one side of the square frame.

[0038] The crushing module 2 includes: a first motor 21 installed on the inclined frame of the bracket 11, a driving wheel 22 connected to the output end of the first motor 21, a driven wheel 23 connected to the driving wheel 22 through a belt 24, and a crushing piece 25 connected to the driven wheel 23. The crushing piece 25 is installed on the square frame, and a screen 26 is arranged on the unloading side of the crushing piece 25; when the plastic scraps need to be recycled, the plastic scraps are put into the hopper 12, and the plastic scraps slide from the hopper 12 to the crushing piece 25, so that the plastic scraps are crushed in the process of the first motor 21 driving the crushing piece 25 to rotate, and the crushed plastic particles fall through the screen 26.

[0039] A fan 5 is provided at the unloading end of the crushing module 2 for blowing the crushed plastic particles into a collecting box (not shown). The collecting box is a conventional container placed on the side of the mounting frame 1 for receiving materials.

[0040] An anti-blocking cutting module 3 is also provided inside the bracket 11. Since plastic waste comes from a wide range of sources and has a variety of shapes, the plastic waste transported to the feeding port by feeding equipment or manually is often placed in a disorderly manner; especially when longer plastic waste appears, it is easy to get stuck at the feeding port of the crushing module 2. This blockage will cause the crushing module 2 to feed poorly, thereby affecting the overall efficiency of plastic waste recycling.

[0041] The anti-blocking and cutting module 3 includes: a second motor 301 installed on the top of the feed hopper 12, and a housing 302; a through hole is provided on the side of the housing 302 facing the second motor 301, so that the output shaft of the second motor 301 can pass through the housing 302 and connect with the parts arranged inside the housing 302. A driving gear 303 is installed at the output end of the second motor 301, and the driving gear 303 is located inside the housing 302; the driving gear 303 is connected to the first driven gear 304 through the first transmission belt 306, and the first driven gear 304 is meshed and connected with a rack 312, and the bottom of the rack 312 is connected to a connecting rod 313, and the bottom of the connecting rod 313 is connected to a hinge shaft 316, and the two sides of the hinge shaft 316 are symmetrically hinged with a pressing plate 315, and a torsion spring is arranged between the hinge shaft 316 and the pressing plate 315, so that the pressing plate 315 is in a horizontal posture in a natural state.

[0042] A limit block 317 or other limit structures may be provided above the pressing plate 315 so that the pressing plate 315 cannot further deflect upward after being in a horizontal position.

[0043] The connecting rod 313 is also slidably connected to an extrusion block 314, which consists of a sliding portion slidably connected to the connecting rod 313, a pressing portion arranged on the sliding portion and bent outward and then downward, and a connecting portion installed on the sliding portion, and the connecting portion is connected to the inner wall of the feed hopper 12; when the pressing plate 315 slides upward, it contacts the pressing portion, and since the connecting portion of the extrusion block 314 is fixed on the inner wall of the feed hopper 12, the pressing plate 315 is deflected downward, so that the plastic waste on the pressing plate 315 falls onto the crushing piece 25, so that it can be crushed; when the pressing plate 315 moves downward and separates from the extrusion block 314, the torsion spring drives the pressing plate 315 to return to a horizontal posture.

[0044] Optionally, the top surface of the pressing plate 315 can be configured as an arc-shaped surface to reduce the possibility of accumulation of plastic waste and facilitate the falling of plastic waste.

[0045] The driving gear 303 is also transmission-connected with a second transmission belt 307, and the second transmission belt 307 is transmission-connected with a second driven gear 305. The second driven gear 305 is coaxially connected with a swing rod 308, and the other end of the swing rod 308 is hinged with a slider 309, and the slider 309 is slidably mounted on a cutting rod 310. The top end of the cutting rod 310 is rotationally mounted on the lower side of the shell 302, and the bottom end of the cutting rod 310 is rotationally connected with a cutting head 311; the driving gear 303 and the first driven gear 304 can be selected as double gears or transmission pulleys; the first transmission belt 306 and the second transmission belt 307 can be chains or transmission belts; the cutting rod 310 can be selected as a cutting rod 310 whose bottom can rotate toward the crushing module 2, so that it is divided into two ends hinged to each other, and a torsion spring is set in the middle to reset it, so as to prevent the plastic waste from being pushed to the outside when the cutting rod 310 rotates outward.

[0046] When the second motor 301 is started, the second motor 301 drives the driving gear 303 to rotate, thereby driving the first driven gear 304 and the second driven gear 305 to rotate respectively. When the second driven gear 305 rotates, it drives the swing rod 308 to swing back and forth, thereby driving the slider 309 to slide up and down along the cutting rod 310, thereby driving the cutting rod 310 to swing back and forth between the entrance of the feed hopper 12 and the inside of the feed hopper 12, thereby cutting or breaking off the plastic waste accumulated at the entrance of the feed hopper 12 during the swinging process, so that the plastic waste can easily enter the crushing module 2 from the feed hopper 12 for crushing; at the same time, the driving gear 303 drives the first driven gear 304 to rotate, thereby driving the pressing plate 315 upward or downward. Slide downward. When the pressure plate 315 slides downward, the plastic waste is pressed onto the crushing piece 25, thereby reducing the possibility that the plastic waste that is still large after partial cutting is difficult to enter the crushing piece 25 for crushing; when the pressure plate 315 slides upward, the extrusion block 314 causes the pressure plate 315 to deflect downward during the sliding process, thereby allowing the plastic waste that falls on the pressure plate 315 to slide off; as a supplement, in this embodiment, the pressure plate 315 can be driven to rise and fall by the forward and reverse rotation of the second motor 301; secondly, the gear sizes of the driving gear 303, the first driven gear 304, and the second driven gear 305 can be designed so that the pressure plate 315 moves up and down once when the cutting rod 310 swings back and forth once or multiple times.

[0047] The cutting rod 310 cooperates with the swing rod 308 and the slider 309 to cut off the long plastic waste or irregularly shaped plastic waste accumulated at the entrance of the hopper 12 by swinging back and forth. The cutting action makes the length of the plastic waste suitable for entering the crushing module 2, avoiding the plastic waste from being stuck at the feed inlet due to being too long. Since plastic waste comes from a wide range of sources and has different shapes, the cutting rod 310 can cut or break off the plastic waste according to the different shapes of the plastic waste, thereby enhancing the adaptability of the equipment to different forms of plastic waste. The extrusion block 314 is fixed to the connection part of the inner wall of the feed hopper 12. When the extrusion block 314 presses the plastic waste, the pressing part forcibly presses the plastic waste onto the crushing piece 25, thereby preventing the plastic waste from accumulating or staying above the crushing piece 25, so that the plastic waste can enter the crushing module 2 faster for subsequent crushing processing. Some plastic waste may be stuck in the feed hopper 12 due to inappropriate size or complex shape, especially longer plastic waste. The pressing action of the extrusion block 314 can effectively push these plastic wastes toward the crushing piece 25, reducing the jamming of plastic waste due to irregular shape, thereby reducing the probability of equipment blockage. It can be seen from the above description that when the plastic waste is accumulated at the entrance of the feed hopper 12 due to being too long or having an irregular shape, the cutting rod 310 divides the plastic waste into appropriate lengths by swinging back and forth, so that it can smoothly pass through the feed port into the crushing module 2; when the plastic waste is cut or set aside, the extrusion block 314 will push the plastic waste to slide down in the direction of the crushing piece 25, accelerating the crushing process of the plastic waste. The synergistic effect of the two can ensure that the waste forms an orderly flow before entering the crushing module 2, avoiding the accumulation or jamming of the waste at the feed port.

[0048] Optional, such as Figures 7 and 8 As shown, the first driven gear 304 is also coaxially connected to the first half gear 318, the first driven gear 304 is transmission-connected to the third driven gear 319, and the third driven gear 319 is coaxially connected to the second half gear 320, wherein the first driven gear 304, the third driven gear 319 and the rack 312 are staggered and not meshed with the rack 312; the first half gear 318 and the second half gear 320 are alternately meshed with the rack 312, and since the first driven gear 304 is transmission-connected to the third driven gear 319, the first driven gear 304 and the third driven gear 319 are The third driven gear 319 rotates in the opposite direction, so when the first half gear 318 and the second half gear 320 are alternately engaged with the rack 312, the rack 312 is driven to move upward or downward intermittently, thereby driving the pressing plate 315 to reciprocate up and down. The advantage of such a design is that there is no need to switch the rotation direction of the output end of the second motor 301. Only the second motor 301 needs to be started to drive the cutting head 311 to intermittently cut the plastic waste while driving the pressing plate 315 to intermittently press down the plastic waste and make the plastic waste slide off the pressing plate 315.

[0049] A grading and screening module 4 is also provided below the crushing module 2, and the grading and screening module 4 is installed on the bracket 11; a motor mounting plate is installed on the outer side of the bracket 11, and a third motor 41 is installed on the motor mounting plate, and the output end of the third motor 41 passes through the outer wall of the bracket 11 and extends into the interior of the bracket 11; a wave member 42 is installed at the output end of the third motor 41, and the wave member 42 is respectively connected to a coarse screen plate 43 and a fine screen plate 44, and the fine screen plate 44 is slidably installed on the inner side of the bracket 11; when the third motor 41 rotates, the coarse screen plate 43 and the fine screen plate 44 are driven to swing back and forth through the wave member 42.

[0050] The wave member 42 includes: an eccentric wheel 421 transmission-connected to the output end of the third motor 41, a wave member 422 installed on the side of the eccentric wheel 421 away from the third motor 41, a sliding block 423 slidably connected to the outer side of the eccentric wheel 421, and hinged rods 424 are connected to the upper and lower sides of the sliding block 423. The hinged rod 424 is slidably connected to a guide block 425, and the guide block 425 is fixedly installed on the bracket 11, and is used to limit the sliding block 423 through the guide block 425 so that the sliding block 423 can only slide up and down; the upper hinged rod 424 is hinged to one end of the coarse screen plate 43, and optionally, the upper hinged rod 424 can be set as a retractable hinged rod 424, and a spring can be set inside it.

[0051] The wave-shaped member 422 is an inclined annular structure, and a first annular groove 4221 is provided in the middle of the annular structure, and a sliding rod 4222 is slidably connected to the first annular groove 4221, and a telescopic rod 4225 is provided on the side of the sliding rod 4222 close to the first annular groove 4221, and a rolling ball or a roller is installed on the end of the telescopic rod 4225 to reduce friction, and a non-retractable straight rod is provided on the side away from the first annular groove 4221; an annular block 4223 is installed on the sliding rod 4222, and the annular block 4223 A second annular groove 42231 is provided on the top, and a telescopic rod 4225 is installed inside the second annular groove 42231. A ball 4224 is rollingly installed on one end of the telescopic rod 4225 located in the second annular groove 42231; the other end of the sliding rod 4222 is connected to the fine screen plate 44; through the design of the sliding rod 4222, the sliding rod 4222 can always slide along the path of the first annular groove 4221. During the sliding process, due to the shape of the wave-shaped member 422, the annular block 4223 It intermittently approaches or moves away from the eccentric wheel 421, so that the sliding rod 4222 swings back and forth in the horizontal direction, thereby driving the fine screen plate 44 to swing back and forth in the horizontal direction; optionally, the corrugated member 422 and the eccentric wheel 421 can be set with different axes, so that the corrugated member 422 can not only drive the fine screen plate 44 to swing back and forth in the horizontal direction, but also shake up and down, thereby improving the screening effect; through the cooperation of the screen 26, the coarse filter and the fine filter, the crushed plastic particles can be better screened, and particles of different particle sizes can be separated, the particle size of the waste material can be efficiently separated, and particles of different particle sizes will be sent to different recycling systems; for example, the waste particles filtered by the coarse filter enter the return box from the discharge port of the mounting frame 1, and then are poured back into the hopper 12 from the return box, and are crushed for the second time by the crushing module 2, and the waste particles filtered by the fine filter can be further processed or recycled, thereby ensuring the purity and quality of waste recycling, improving the reuse value and improving the effect of subsequent reuse.

[0052] First springs 45 are installed at both ends of the coarse screen plate 43 close to the wave member 42, and second springs 46 are installed at both ends of the coarse screen plate 43 away from the wave member 42. The length of the first spring 45 is greater than that of the second spring 46, so that the coarse screen plate 43 is inclined; through the arrangement of the first spring 45 and the second spring 46, not only can a buffering effect be played and the swinging can be enhanced, but also the impact force of the buffer screen plate during vibration can be reduced, so that the swinging of the screen plate is more stable, avoiding excessive vibration to cause damage to the screen 26 or uneven screening, and can also make the plastic waste move to one side of the second spring 46 during the swinging process, so as to facilitate the discharge of large-particle waste screened from one side of the second spring 46.

[0053] Optionally, a weighing device is installed at the inner bottom of the hopper 12. When the weight measured by the weighing device exceeds a threshold value, the second motor 301 is started to avoid energy waste caused by continuous operation.
