Description

Technical Field

[0001] The invention relates to the technical field of waterproof coiled material recovery devices, in particular to a device for recovering scraps used in processing waterproof coiled materials. Background Art

[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. When waterproof membrane is used, a large amount of scraps will be discarded, and manufacturers will recycle and reuse the membrane through recycling equipment. Polypropylene is a common waterproof membrane.

[0003] However, when the existing waterproof polypropylene is recycled, the polypropylene scraps are directly discharged through the discharge hopper, and multiple waterproof polypropylene scraps will be entangled together, which is easy to block the feed port and lead to low feeding efficiency of the recycling process; in order to reduce environmental pollution during the recycling of polypropylene, some polypropylene will be cold granulated by directly extruding the polypropylene material, and the extruded polypropylene material rods are cut into granules to complete the recycling of the polypropylene material. Since the polypropylene strips are directly extruded, the gaps between the multiple polypropylene strips are large, which will lead to poor extrusion effect and affect the granulation effect; an observation window is fixedly connected to the casing of the waterproof polypropylene recycling machine by bolts. When the cutter needs to be inspected and maintained, the observation window and the cutter need to be disassembled. The installation and replacement efficiency of the observation window and the cutter is low. At the same time, when the collecting cylinder for collecting polypropylene particles is full, it is necessary to stop the machine and replace the collecting cylinder, resulting in reduced processing efficiency.

[0042] The guide structure 4 includes a rotating shaft 401 and two connecting plates 402 rotatably connected to the two ends of the rotating shaft 401. The rotating shaft 401 is fixedly connected to the feed shell 202, and a guide roller 406 is rotatably connected between the two connecting plates 402. A plurality of limiting grooves 403 are arranged in a circumferential array at the bottom end of the connecting plate 402. A limiting rod 404 with a J-shaped cross-section is slidably connected to the feed shell 202. The limiting rod 404 is engaged with the limiting groove 403. A first spring 405 is fixedly connected between the limiting rod 404 and the feed shell 202; a sliding bar 407 is slidably connected inside the connecting plate 402, and a pressing roller 408 is rotatably connected between the two sliding bars 407.

During recycling, the pressure roller 408 is pulled, and the pressure roller 408 drives the slide bar 407 to slide, and the slide bar 407 drives the mounting block 410 to slide, thereby driving the guide rod 411 to slide, and the second spring 412 is compressed, and then a plurality of polypropylene scraps are passed through the gap between the guide roller 406 and the pressure roller 408. The guide roller 406 is provided with a plurality of grooves for conveniently limiting the polypropylene strips. Then the pressure roller 408 is released, and the second spring 412 is reset, thereby driving the guide rod 411 and the mounting block 410 to reset, driving the pressure roller 408 and the guide roller 406 to guide and limit the polypropylene strips. The end of the polypropylene strip is passed through the feed port 314 of the feed housing 202. During granulation, the third motor 307 is started. The third motor 307 drives the first pulley 304 at its end to rotate. The first pulley 304 drives another first pulley 304 on the drive shaft 301 to rotate, thereby driving the drive shaft 301 to rotate. The rotation of the drive shaft 301 drives the drive gear 303 at the end to rotate. The two drive gears 303 are meshed. When one of the drive gears 303 rotates, it drives the other drive gear 303 to rotate in the opposite direction. The other drive gear 303 rotates in the opposite direction and drives the other drive shaft 301 to rotate in the opposite direction. The two drive shafts 301 rotate in opposite directions, so that the two drawing rollers 302 rotate in opposite directions.The pulling roller 302 then pulls the polypropylene strip to be discharged. The pulling roller 302 is provided with a plurality of strip grooves in a circumferential array, which improves the discharge effect of the polypropylene. At the same time, the rotation of the driving shaft 301 will drive the second pulley 305 to rotate. The rotation of the second pulley 305 drives the second pulley 305 on the transmission shaft 308 to rotate through the belt, thereby driving the transmission shaft 308 to rotate. The rotation of the transmission shaft 308 drives the first bevel gear 310 to rotate. The rotation of the first bevel gear 310 drives the second bevel gear 311 to rotate. The rotation of the second bevel gear 311 drives the connecting shaft 312 to rotate. The connecting shaft 312 drives the chopping knife 313 to rotate to cut the polypropylene strip. The polypropylene strip is initially cut off, which improves the subsequent polypropylene extrusion. The effect is to reduce the gap during polypropylene extrusion, thereby improving the granulation effect. The cut polypropylene segments enter the interior of the screw extruder housing 203 from the discharge pipe 206. The first motor 205 drives the spiral blade 204 to rotate. The spiral blade 204 rotates continuously to feed. Since the end of the screw extruder housing 203 is a trapezoidal structure, the spiral blade 204 gradually loads and pressurizes, and finally squeezes the polypropylene segments into blocks, and continues to squeeze and discharge from the discharge hole 207. The extruded polypropylene rod-shaped material is discharged. At the same time, the second motor 208 drives the connecting structure 6 and the cutter 209 to rotate. The cutter 209 cuts multiple polypropylene rod-shaped materials into particles, and discharges them from the lower hopper 210 and enters the collection structure 7.

[0043] Specifically, Figure 1 , Figure 6 , Figure 8 , Fig.10 , Fig.11 , Fig.13 and Fig.14 As shown, the observation structure 5 includes an observation window 501 and four "I"-shaped push rods 502 slidably connected to the housing 201. The housing 201 is equipped with an observation window 501, and the top of the push rod 502 abuts against the observation window 501. A tension spring 503 is fixedly connected between the push rod 502 and the housing 201. Three groups of fixed seats 504 are fixedly connected to the housing 201, and each group of the fixed seats 504 is provided with two, wherein two parallel fixed rods 504 are fixedly connected between two groups of the fixed seats 504. 05, two pressing plates 506 are slidably connected to the two fixing rods 505, the pressing plates 506 are in contact with the observation window 501, a third spring 507 is fixedly connected between the pressing plates 506 and the fixing seat 504, and a slot 511 is provided on the fixing seat 504; two clamping rods 508 with a J-shaped cross section are slidably connected to the housing 201, the end cross section of the clamping rod 508 is a trapezoidal structure, a fourth spring 509 is fixedly connected between the clamping rod 508 and the housing 201, and a clamping hole 510 is provided on the pressing plate 506;

[0044] The connection structure 6 includes a connection shaft 601 fixedly connected to the end of the second motor 208 and a connection sleeve 602 inserted on the connection shaft 601, the end section of the connection shaft 601 is a hexagonal structure, the interior of the connection sleeve 602 is slidably connected with a flower shaft 603 with a T-shaped cross section, the end section of the flower shaft 603 is "petal" shaped, a fifth spring 604 is fixedly connected between the flower shaft 603 and the connection sleeve 602, a rotating seat 605 is fixedly connected to the screw extruder housing 203, a cutter 209 is fixedly connected to the flower shaft 603, and the cutter 209 is rotatably connected to the rotating seat 605, the bottom end of the observation window 501 is fixedly connected to a limiting strip 608, and the cross section of the bottom end of the limiting strip 608 is a U-shaped structure; a limiting ring 606 is fixedly connected to the flower shaft 603, and the outer rotation of the limiting ring 606 is connected to a limiting wheel 607, and the limiting wheel 607 is rotatably connected to the limiting strip 608;When the observation window 501 needs to be opened, the two pressure plates 506 can be slid, and the sliding of the pressure plates 506 compresses the third spring 507. When the pressure plates 506 no longer block and interfere with the observation window 501, the tension spring 503 is reset and drives the push rod 502 to rise. The push rod 502 pushes the observation window 501 out, making it convenient to take the observation window 501. At the same time, the sliding of the pressure plate 506 will interfere with the clamping rod 508. The end section of the clamping rod 508 is a trapezoidal structure. After being interfered, the clamping rod 508 will slide downward, compressing the fourth spring 509. When the clamping hole 510 of the pressure plate 506 moves to the top of the clamping rod 508, The fourth spring 509 is reset to drive the clamping rod 508 to reset, and the clamping rod 508 is then engaged with the clamping hole 510, thereby fixing the pressure plate 506, and then the observation window 501 is inserted into the slot 511 of the two adjacent fixing seats 504, and then the observation window 501 is placed during maintenance. When the observation window 501 is picked up, it will drive the limit bar 608 to rise, and the limit bar 608 rises and no longer plugs into the limit wheel 607 on the flower shaft 603. At this time, the flower shaft 603 can be slid, and the flower shaft 603 drives the cutter 209 to separate from the rotating seat 605. The fifth spring 604 is compressed, and then the connecting sleeve 602 is removed from the connecting shaft 601, and then the cutter 209 is quickly disassembled, which improves the installation and disassembly efficiency of the cutter 209. When installing the cutter 209, first plug the connecting sleeve 602 onto the connecting shaft 601, then loosen the flower shaft 603, the fifth spring 604 resets to drive the flower shaft 603 and the cutter 209 to reset, the cutter 209 is plugged into the rotating seat 605, and then the observation window 501 is installed. When installing the observation window 501, the bottom end of the limit strip 608 needs to be inserted into the groove of the limit wheel 607 to prevent the flower shaft 603 from moving back and forth, thereby improving the stability during rotation. When cutting pellets, the second motor 208 drives the engagement sleeve 602 to be connected to the engagement shaft 601, and then the flower shaft 603 is loosened. The connecting shaft 601 rotates, the connecting shaft 601 drives the connecting sleeve 602 to rotate, and the connecting sleeve 602 drives the flower shaft 603 and the cutter 209 to rotate, thereby pelletizing the polypropylene material extruded into a rod. When installing the observation window 501, it is necessary to press the observation window 501 downward so that the top of the observation window 501 and the housing 201 are in the same plane, and then press the clamping rod 508 so that the clamping rod 508 is not engaged with the clamping hole 510. At this time, the third spring 507 is reset to drive the pressing plate 506 to slide on the fixing rod 505, and the pressing plate 506 then slides to the top of the observation window 501 to prevent the observation window 501 from popping out. ;

The baffle plate 703 is touched, and the collection box 706 is continuously pushed, so that the baffle plate 703 slides and no longer blocks the bottom end of the lower hopper 210, so that the cut particles can fall into the interior of the collection box 706, and the collection box 706 will resist the block 710, and the top of the block 710 is a trapezoidal structure, so the block 710 will slide downward in the slot 711, and the seventh spring 712 on the mounting rod 709 is compressed until the collection box 706 passes over the block 710, and the seventh spring 712 is reset to drive the block 710 to reset, and the block 710 cooperates with the baffle plate 703 to clamp the collection box 706. When the collection box 706 needs to be replaced, the block 710 is stepped on downward. The block 710 no longer blocks the collection box 706, and the sixth spring 704 is reset to drive the baffle 703 to reset. The baffle 703 gradually blocks the outlet of the lower hopper 210. At this time, the produced particles will accumulate in the lower hopper 210, and then the collection box 706 is replaced to prevent the particles from falling to the ground when the collection box 706 is replaced. The setting of the block 705 prevents the baffle 703 from sliding forward excessively and separating from the fixed shaft 702. The setting of the fixed shaft 702 improves the sliding stability of the baffle 703 and improves the shielding effect. The setting of the mounting rod 709 improves the sliding stability of the block 710 and prevents the seventh spring 712 from running off.

[0046] When the present invention is in use, first, when recycling the processing scraps of waterproof polypropylene, the limiting rod 404 is pressed first, the first spring 405 is compressed, and the limiting rod 404 is no longer engaged with the limiting groove 403 on the connecting plate 402, the connecting plate 402 can be rotated to turn the connecting plate 402 to a suitable angle, thereby improving the guiding effect on the polypropylene scraps. After rotating to a suitable position, the limiting rod 404 is released, the first spring 405 is reset, and the limiting rod 404 is driven to re-engage with the limiting groove 403, thereby fixing the position of the connecting plate 402. When the recycling of the polypropylene scraps is stopped, the angle of the connecting plate 402 can also be adjusted to make it stored, thereby improving the space utilization rate. When recycling, the pressure roller 408 is pulled, and the pressure roller 408 drives the slide bar 407 to slide, and the slide bar 407 drives the mounting block 410 to slide, thereby driving the guide rod 411 to slide, the second spring 412 is compressed, and then a plurality of polypropylene scraps pass through the gap between the guide roller 406 and the pressure roller 408. The guide roller 406 is provided with a plurality of grooves to facilitate the limiting of the polypropylene strips. Then the pressure roller 408 is released, the second spring 412 is reset, thereby driving the guide rod 411 and the mounting block 410 to reset, driving the pressure roller 408 and the guide roller 406 to guide and limit the polypropylene strips, and passing the end of the polypropylene strip through the feed port 314 of the feed shell 202. During granulation, the third motor 307 is started, and the third motor 307 drives the first pulley 304 at its end to rotate. The first pulley 304 drives another first The pulley 304 rotates, thereby driving the drive shaft 301 to rotate. The rotation of the drive shaft 301 drives the drive gear 303 at the end to rotate. The two drive gears 303 are meshed. When one of the drive gears 303 rotates, it will drive the other drive gear 303 to rotate in the opposite direction. The other drive gear 303 rotates in the opposite direction and then drives the other drive shaft 301 to rotate in the opposite direction. The two drive shafts 301 rotate in opposite directions, causing the two drawing rollers 302 to rotate in opposite directions. The drawing rollers 302 then pull the polypropylene strip to be discharged. The drawing rollers 302 are provided with a plurality of strip grooves in a circumferential array, which improves the discharge effect of the polypropylene. At the same time, the rotation of the drive shaft 301 will drive the second pulley 305 to rotate. The rotation of the second pulley 305 passes through the pulley The belt drives the second pulley 305 on the transmission shaft 308 to rotate, thereby driving the transmission shaft 308 to rotate. The rotation of the transmission shaft 308 drives the first bevel gear 310 to rotate. The rotation of the first bevel gear 310 drives the second bevel gear 311 to rotate. The rotation of the second bevel gear 311 drives the connecting shaft 312 to rotate. The connecting shaft 312 drives the chopping knife 313 to rotate to cut the polypropylene strips. The polypropylene strips are initially cut off, which improves the effect of subsequent polypropylene extrusion and reduces the gap during polypropylene extrusion, thereby improving the granulation effect. The cut polypropylene segments enter the interior of the screw extruder housing 203 from the discharge pipe 206. The first motor 205 drives the spiral blade 204 to rotate. The spiral blade 204 continuously rotates to feed. Since the end of the screw extruder housing 203 is a trapezoidal structure,The spiral blade 204 gradually loads and pressurizes, and finally squeezes the polypropylene segment into blocks, and continues to squeeze and discharge from the discharge hole 207. At the same time, the second motor 208 drives the connecting structure 6 and the cutter 209 to rotate, and the cutter 209 cuts the multiple polypropylene rod-shaped materials into particles, and discharges them from the lower hopper 210 and enters the collection structure 7;

[0047] Then, when it is necessary to open the observation window 501, the two pressure plates 506 can be slid, and the sliding of the pressure plates 506 compresses the third spring 507. When the pressure plates 506 no longer block and interfere with the observation window 501, the tension spring 503 is reset and drives the push rod 502 to rise. The push rod 502 pushes the observation window 501 out, making it convenient to take the observation window 501. At the same time, the sliding of the pressure plate 506 will interfere with the card rod 508. The end cross-section of the card rod 508 is a trapezoidal structure. After being interfered, the card rod 508 will slide downward, causing the fourth spring 509 to compress. When the card hole 510 of the pressure plate 506 moves to the position above the card rod 508 When the fourth spring 509 is reset, the clamping rod 508 is reset, and the clamping rod 508 is then engaged with the clamping hole 510, thereby fixing the pressure plate 506, and then the observation window 501 is inserted into the slot 511 of the two adjacent fixing seats 504, and then the observation window 501 is placed during maintenance. When the observation window 501 is picked up, it will drive the limit bar 608 to rise, and the limit bar 608 rises and no longer plugs into the limit wheel 607 on the flower shaft 603. At this time, the flower shaft 603 can be slid, and the flower shaft 603 drives the cutter 209 to separate from the rotating seat 605, and the fifth spring 604 is compressed, and then the connecting sleeve 602 is removed from the connecting sleeve The cutter 209 is removed from the shaft 601, and then the cutter 209 is quickly disassembled, which improves the installation and disassembly efficiency of the cutter 209. When installing the cutter 209, first plug the connecting sleeve 602 onto the connecting shaft 601, then loosen the flower shaft 603, the fifth spring 604 resets to drive the flower shaft 603 and the cutter 209 to reset, the cutter 209 is plugged into the rotating seat 605, and then the observation window 501 is installed. When installing the observation window 501, the bottom end of the limit strip 608 needs to be inserted into the groove of the limit wheel 607 to prevent the flower shaft 603 from moving back and forth, thereby improving the stability during rotation. When cutting pellets, the second motor 208 drives the engagement sleeve 602 to engage with the engagement sleeve 603, and then the flower shaft 603 is loosened. The connecting shaft 601 rotates, and the connecting shaft 601 drives the connecting sleeve 602 to rotate, and the connecting sleeve 602 drives the flower shaft 603 and the cutter 209 to rotate, and then the polypropylene material extruded into a rod is pelletized. When installing the observation window 501, it is necessary to press the observation window 501 downward so that the top of the observation window 501 and the housing 201 are in the same plane, and then press the clamping rod 508 so that the clamping rod 508 is not engaged with the clamping hole 510. At this time, the third spring 507 is reset to drive the pressure plate 506 to slide on the fixing rod 505, and the pressure plate 506 then slides to the top of the observation window 501 to prevent the observation window 501 from popping out;

[0048] Finally, during granulation, the collecting box 706 is pushed to the bottom of the lower hopper 210, and the collecting box 706 will resist the baffle 703. The collecting box 706 is continuously pushed so that the baffle 703 slides and no longer blocks the bottom end of the lower hopper 210, so that the cut particles can fall into the collecting box 706. The collecting box 706 will resist the card block 710, and the top of the card block 710 is a trapezoidal structure, so the card block 710 will slide downward in the card slot 711, and the seventh spring 712 on the mounting rod 709 is compressed until the collecting box 706 passes over the card block 710. The seventh spring 712 resets and drives the card block 710 to reset. The card block 710 cooperates with the baffle 703 to clamp the collecting box 706. When it needs to be replaced When collecting box 706 is opened, block 710 is stepped down, and block 710 no longer blocks collecting box 706. The sixth spring 704 is reset to drive baffle 703 to reset, and baffle 703 gradually blocks the outlet of lower hopper 210. At this time, the produced particles will accumulate in lower hopper 210, and then collecting box 706 is replaced, which prevents the particles from falling to the ground when replacing collecting box 706. The setting of block 705 prevents baffle 703 from sliding forward excessively and separating from fixed shaft 702. The setting of fixed shaft 702 improves the sliding stability of baffle 703 and improves the shielding effect. The setting of mounting rod 709 improves the sliding stability of block 710 and prevents the seventh spring 712 from running off.
