Description

Technical Field

[0001] This invention relates to the field of rain boot production equipment technology, and in particular to a high-efficiency, wear-resistant, fully automatic injection molding machine for rain boot production. Background Technology

[0002] Rain boots, also known as rain boots, come in many styles. Low-top rain boots resemble sneakers in appearance, mid-top rain boots have a shaft height of about 10 centimeters above the ankle, and high-top rain boots reach the knee. Ordinary people commonly wear mid- or low-top rain boots, while some workers in specialized professions require high-top rain boots as protective gear. Rain boots are very common in our lives, and most are currently made of rubber. During production, rain boots are injection molded using an injection molding machine.

[0003] Because the plastic granules used in rain boot injection molding inevitably experience friction during transportation or storage, static electricity is easily generated during friction, attracting a lot of dust. Even if antistatic agents are added to the plastic granules, the antistatic agents cannot cover the entire surface of the plastic granules, and static electricity is still generated during friction with other plastic granules. Furthermore, this dust is fed into the rain boot injection molding machine along with the plastic granules. This not only affects the appearance of the finished rain boots, but also makes it easy for dust to accumulate on the surface of the rain boots. During use, the dust falls off the surface of the rain boots, forming small pits, which increases the probability of the rain boots cracking and reduces the wear resistance of the rain boots themselves. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency, wear-resistant, fully automatic injection molding machine for rain boot production in order to solve the above-mentioned problems, thereby improving the problem that rain boots produced by existing fully automatic injection molding machines for rain boot production are prone to dust adhesion, which reduces the quality of finished rain boots.

[0005] The present invention achieves the above-mentioned objectives through the following technical solution: a high-efficiency, wear-resistant, fully automatic injection molding machine for rain boot production, comprising a frame, an injection molding system mounted on the upper end of the frame, a control system mounted on the surface of the frame, and a feeding device fixedly connected to the upper end of the injection molding system; wherein, the feeding device includes a guide tank fixedly connected to the upper end of the injection molding system, a screening mechanism mounted inside the guide tank, one end of the screening mechanism penetrating to the outside of the guide tank, a cleaning mechanism mounted at the lower end of the screening mechanism, one end of the cleaning mechanism penetrating to the outside of the guide tank, and an intermittent feeding mechanism mounted on the surface of the guide tank, one end of the intermittent feeding mechanism penetrating to the inside of the guide tank.

[0006] Preferably, the material guide tank has a cleaning chamber inside and a material discharge chamber at its lower end. The cleaning mechanism includes evenly distributed conductive rollers, a servo motor, an air pump, and a dust filter. The conductive rollers are rotatably connected to the inner wall of the cleaning chamber, and the angle between the conductive rollers and the horizontal plane is 15 degrees. The servo motor is fixedly connected to the surface of the material guide tank, and a worm gear is fixedly connected to the output shaft of the servo motor. The end of the worm gear away from the servo motor passes through the material guide tank and extends into the interior of the cleaning chamber. A meshing connection is fixedly connected to the surface of the conductive rollers. The worm gear is connected to the conductive roller, and the surface of the conductive roller has ash guiding holes distributed in a ring around the center line of the conductive roller. The air pump is fixedly connected to the end of the material guide tank away from the servo motor. The air inlet end of the air pump is fixedly connected to a first gas distributor communicating with the air pump. The end of the first gas distributor away from the air pump passes through the material guide tank and the cleaning chamber in sequence and is fixedly connected to the inner top wall of the cleaning chamber. The air outlet end of the first gas distributor is fixedly connected to a second gas distributor that is evenly distributed and communicates with the first gas distributor. The output end of the second gas distributor is fixedly connected to a... High-pressure nozzles, evenly distributed and connected to the second gas distributor, have their outlets positioned directly above the conductive roller. A dust filter cartridge is inserted into the inner bottom wall of the cleaning chamber, with its end away from the air pump penetrating the cleaning chamber and extending to the outside of the material guide tank. A material drop pipe, fixedly connected to the cleaning chamber, is driven to the downward-opening inner wall of the conductive roller. The lower end of the material drop pipe penetrates the cleaning chamber and extends into its interior. By incorporating this cleaning mechanism, the conductive roller can conduct away static electricity from the surface of the plastic granules it contacts. Simultaneously, a servo motor can be activated via a worm gear and... The worm gear drives the conductive roller to rotate and tumble the plastic granules, accelerating the separation rate of dust and plastic granules. At the same time, the air pump blows away the dust that permeates the conductive roller through the first gas distributor, the second gas distributor, and the high-pressure nozzle. This allows for a more thorough separation of plastic granules from dust, keeping the plastic granules entering the injection molding system clean. This not only reduces the injection pressure of dust on the injection molding system and reduces the maintenance frequency of the injection molding system, thereby improving the production efficiency of the fully automatic injection molding machine for rain boots, but also improves the appearance and quality of the finished rain boots produced by the injection molding system.

[0007] Preferably, the surface of the conductive roller is rotatably connected to two ring frames, both of which are fixedly connected to the cleaning chamber. The worm wheel is disposed inside the lower ring frame, and the end of the worm away from the servo motor extends to the outside of the lower ring frame. This can prevent dust from falling onto the meshing point of the worm and the worm wheel, and reduce the transmission resistance between the worm and the worm wheel.

[0008] Preferably, a connecting shaft is rotatably connected between two adjacent upper and lower ring frames. A guide block is fixedly connected to the surface of the connecting shaft in a ring shape around the center line of the connecting shaft. The end of the guide block closest to the center line of the conductive roller that is away from the connecting shaft extends into the interior of the adjacent ash guide hole. The distance between two adjacent guide blocks and two adjacent ash guide holes is the same, which can keep the ash guide holes unobstructed to ensure normal gas flow.

[0009] Preferably, the inside of the material guide tank is provided with an air guide slope that communicates with the bottom wall of the cleaning chamber. An air guide pipe is fixedly connected to the bottom wall of the air guide slope. The lower end of the air guide pipe extends to the outside of the material guide tank. The air guide pipe is spiral in shape. As the gas is discharged to the outside through the air guide pipe, the gas also carries the heat of the air guide pipe and the surrounding material guide tank to avoid the temperature inside the material discharge chamber becoming too high, which could cause the plastic particles to melt and adhere to the inside of the material discharge chamber.

[0010] Preferably, the upper end of the feed tank has a processing chamber. The screening mechanism includes a ring belt and a hopper. The ring belt is disposed inside the processing chamber, and its surface has ring-shaped screening holes. Two drive shafts, both rotatably connected to the processing chamber, are connected to the inner side of the ring belt. One end of one drive shaft is fixedly connected to a drive motor. The end of the drive motor away from the drive shaft passes through the processing chamber and the feed tank and is fixedly connected to the feed tank. The hopper is fixedly connected to the inner bottom wall of the processing chamber. Two crushing wheels are rotatably connected to the inner wall of the hopper. The ends of the two crushing wheels near the drive motor extend to the outside of the hopper. The inner side of the ring belt has evenly distributed screening holes, all fixedly connected to the processing chamber. The first guide hopper is connected to the first guide hopper, and two adjacent first guide hoppers are fixedly connected to each other. The lower end of the discharge hopper is fixedly connected to a second guide hopper that communicates with the discharge hopper. The lower ends of the first guide hopper and the second guide hopper pass through the processing chamber and the cleaning chamber in sequence and are connected to the inner wall of the upward opening of the adjacent conductive roller. By setting a screening mechanism, the screening mechanism can screen out excessively large plastic particles and crush them into qualified diameters. This not only reduces the cleaning burden of the cleaning mechanism, but also reduces the melting burden of the injection molding system, so that the plastic particles can be melted more easily. In addition, in conjunction with the intermittent guiding mechanism, the plastic particles can be guided into the conductive roller, reducing the turning burden of a certain conductive roller, thereby improving the overall cleaning effect of the cleaning mechanism.

[0011] Preferably, both ends of the ring belt are fixedly connected to toothed belts, and the inner side of the toothed belts is connected to pulleys that are connected to the drive shaft. One end of the pulley away from the drive shaft is fixedly connected to the drive motor. This enables the drive motor to drive the ring belt more stably and reduces the probability of the ring belt slipping.

[0012] Preferably, gears are fixedly connected to the surfaces of both crushing wheels, and the two gears mesh with each other. A sprocket is fixedly connected to the surface of one of the crushing wheels and the output shaft of the drive motor. A chain meshes with the surface of one of the sprockets and is connected to the other sprocket. The drive motor can synchronously drive the two crushing wheels to rotate, eliminating the need for a separate power source for the two crushing wheels and reducing the cost of the screening mechanism.

[0013] Preferably, the intermittent feeding mechanism includes a hydraulic cylinder fixedly connected to the end of the feeding tank away from the servo motor. The output shaft of the hydraulic cylinder is fixedly connected to an adjusting frame. Both ends of the adjusting frame penetrate the feeding tank and respectively extend into the processing chamber and the discharge chamber. The upward-facing end of the adjusting frame is fixedly connected to a feed hopper slidably connected to the processing chamber. The feed hopper is positioned above the belt. The downward-facing end of the adjusting frame is fixedly connected to a guide plate slidably connected to the discharge chamber. The upper end of the guide plate has a guide port communicating with the adjacent discharge pipe. By setting up an intermittent feeding mechanism, the hydraulic cylinder can simultaneously drive the feed hopper and the guide plate to move back and forth through the adjusting frame. The feed hopper guides the plastic particles along the way to different positions on the belt to avoid the plastic particles from concentrating in one of the first feed hoppers, thus reducing the cleaning burden on the subsequent cleaning mechanism. At the same time, the guide plate drives the guide port to move back and forth. When the guide port is connected to a certain discharge pipe, the plastic particles in the discharge pipe can fall normally into the discharge chamber. This can avoid the probability of the discharge chamber being blocked due to excessive plastic particle discharge.

[0014] Preferably, the feed tank has a guide groove inside that communicates with the processing chamber, the surface of the feed hopper is fixedly connected to a slide plate that is slidably connected to the guide groove, and the guide plate is fixedly connected to two sides parallel to the servo motor with slide bars. The surface of the slide bars is slidably connected to a slide frame that is fixedly connected to the discharge chamber. This makes the reciprocating movement of the feed hopper and the guide plate more stable and reduces the running resistance of the hydraulic cylinder.

[0015] The beneficial effects of this invention are:

[0016] By incorporating a cleaning mechanism, the conductive roller can conduct away static electricity from the surface of the plastic granules it contacts. Simultaneously, the servo motor drives the conductive roller to rotate and tumble the plastic granules via a worm gear and worm wheel, accelerating the separation rate of dust and plastic granules. At the same time, the air pump blows away the dust diffused in the conductive roller through the first gas distributor, the second gas distributor, and the high-pressure nozzle. This ensures a more thorough separation of plastic granules from dust, keeping the plastic granules entering the injection molding system clean. This not only reduces the injection pressure of the injection molding system due to dust and lowers the maintenance frequency of the injection molding system, thereby improving the production efficiency of the fully automatic injection molding machine for rain boots, but also enhances the aesthetics and quality of the finished rain boots produced by the injection molding system.

[0017] By setting up a screening mechanism, the screening mechanism can screen out excessively large plastic particles and crush them into qualified diameters. This not only reduces the cleaning burden of the cleaning mechanism, but also reduces the melting burden of the injection molding system, making it easier for the plastic particles to be melted. In addition, in conjunction with the intermittent feeding mechanism, the plastic particles can be guided into the conductive roller, reducing the turning burden of a certain conductive roller, thereby improving the overall cleaning effect of the cleaning mechanism.

[0018] By setting up an intermittent feeding mechanism, the hydraulic cylinder can simultaneously drive the feed hopper and the guide plate to move back and forth through the adjusting frame. The feed hopper guides the plastic particles along the way to different positions on the belt to avoid the plastic particles from concentrating in one of the first feed hoppers, thus reducing the cleaning burden on the subsequent cleaning mechanism. At the same time, the guide plate drives the guide port to move back and forth. When the guide port is connected to a certain discharge pipe, the plastic particles in the discharge pipe can fall normally into the discharge chamber. This can avoid the probability of the discharge chamber being blocked due to excessive plastic particle discharge. Attached Figure Description

Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] In practical implementation: such as Figure 1-12 As shown, a high-efficiency, wear-resistant, fully automatic injection molding machine for rain boot production includes a frame 1, an injection molding system 2 mounted on the upper end of the frame 1, a control system 3 mounted on the surface of the frame 1, and a feeding device 4 fixedly connected to the upper end of the injection molding system 2. The feeding device 4 includes a guide tank 5 fixedly connected to the upper end of the injection molding system 2, a screening mechanism 6 installed inside the guide tank 5, one end of the screening mechanism 6 extending to the outside of the guide tank 5, a cleaning mechanism 7 installed at the lower end of the screening mechanism 6, one end of the cleaning mechanism 7 extending to the outside of the guide tank 5, and an intermittent feeding mechanism 8 mounted on the surface of the guide tank 5, one end of the intermittent feeding mechanism 8 extending to the inside of the guide tank 5.

[0034] like Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 11As shown, the material guide tank 5 has a cleaning chamber 501 inside, and a material discharge chamber 502 at the lower end of the material guide tank 5. The cleaning mechanism 7 includes evenly distributed conductive rollers 701, a servo motor 702, an air pump 706, and a dust filter cartridge 710. The conductive rollers 701 are all rotatably connected to the inner wall of the cleaning chamber 501. The angle between the conductive rollers 701 and the horizontal plane is 15 degrees. The servo motor 702 is fixedly connected to the surface of the material guide tank 5. The output shaft of the servo motor 702 is fixedly connected to a worm gear 703. The end of the worm gear 703 away from the servo motor 702 is... A conductive roller 701 extends through the material guide tank 5 and into the cleaning chamber 501. A worm gear 704, meshing with a worm 703, is fixedly connected to the surface of the conductive roller 701. Dust guide holes 705 are arranged in a ring around the center line of the conductive roller 701. An air pump 706 is fixedly connected to the end of the material guide tank 5 furthest from the servo motor 702. A first gas distributor 707, communicating with the air pump 706, is fixedly connected to the air inlet end of the air pump 706. The end of the first gas distributor 707 furthest from the air pump 706 passes through the material guide tank 5. A cleaning chamber 501 is fixedly connected to its inner top wall. A second gas splitter 708, evenly distributed and communicating with the first gas splitter 707, is fixedly connected to the outlet end of the first gas splitter 707. High-pressure nozzles 709, evenly distributed and communicating with the second gas splitter 708, are fixedly connected to the output end of the second gas splitter 708. The outlet end of the high-pressure nozzles 709 is positioned directly above the conductive roller 701. A dust filter cartridge 710 is inserted into the inner bottom wall of the cleaning chamber 501, and is located away from the air pump 701. One end of 6 passes through the cleaning chamber 501 and extends to the outside of the guide tank 5. The inner wall of the downward opening of the conductive roller 701 is connected to a discharge pipe 711 that is fixedly connected to the cleaning chamber 501. The lower end of the discharge pipe 711 passes through the cleaning chamber 501 and extends to the inside of the discharge chamber 502. Two ring frames 712, both of which are fixedly connected to the cleaning chamber 501, are rotatably connected to the surface of the conductive roller 701. The worm gear 704 is located inside the lower ring frame 712. The end of the worm 703 away from the servo motor 702 passes through to the outside of the lower ring frame 712.A connecting shaft 713 is rotatably connected between two adjacent upper and lower ring frames 712. Guide blocks 714, arranged in a ring around the center line of the connecting shaft 713, are fixedly connected to the surface of the connecting shaft 713. The end of the guide block 714 closest to the center line of the conductive roller 701, away from the connecting shaft 713, extends into the interior of an adjacent dust guide hole 705. The distance between two adjacent guide blocks 714 and two adjacent dust guide holes 705 is the same. {During the operation of the conductive roller 701, the conductive roller 701 drives the guide blocks 714 to rotate through the dust guide holes 705.} The connecting shaft 713 rotates, which in turn rotates all the guide blocks 714. As the guide blocks 714 penetrate the dust guide hole 705, they can push any plastic particles stuck inside the dust guide hole 705 back into the conductive roller 701, ensuring the dust guide hole 705 remains unobstructed. The guide tank 5 has an internal air guide slope that communicates with the bottom wall of the cleaning chamber 501. An air guide pipe 503 is fixedly connected to the inner bottom wall of the air guide slope. The lower end of the air guide pipe 503 extends to the outside of the guide tank 5, and the air guide pipe 503 is spiral-shaped.

[0035] like Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the upper end of the feed tank 5 has a processing chamber 504. The screening mechanism 6 includes a ring belt 601 and a discharge hopper 605. The ring belt 601 is disposed inside the processing chamber 504. The surface of the ring belt 601 has screen holes 602 distributed in a ring. The inner side of the ring belt 601 is connected to two drive shafts 603, both of which are rotatably connected to the processing chamber 504. One end of one of the drive shafts 603 is fixedly connected to a drive motor 604. The end of the drive motor 604 away from the drive shaft 603 passes through the processing chamber 504 and the feed tank 5 in sequence. The material discharge hopper 605 is fixedly connected to the inner bottom wall of the processing chamber 504 and is fixedly connected to the guide tank 5. Two crushing wheels 606 are rotatably connected to the inner wall of the material discharge hopper 605. The ends of the two crushing wheels 606 near the drive motor 604 extend to the outside of the material discharge hopper 605. The inner side of the ring belt 601 is provided with evenly distributed first guide hoppers 607, all of which are fixedly connected to the processing chamber 504. Two adjacent first guide hoppers 607 are fixedly connected to each other. The lower end of the material discharge hopper 605 is fixedly connected to a second guide hopper 608 that communicates with the material discharge hopper 605. The lower ends of the first guide hopper 607 and the second guide hopper 608 sequentially penetrate the processing chamber 504 and the cleaning chamber 501, and are connected to the inner wall of the upward-facing opening of the adjacent conductive roller 701. A series of unblocking blocks are fixedly connected to the surface of the drive shaft 603, arranged in a ring around the center line of the drive shaft 603. One end of each unblocking block penetrates into the interior of the adjacent screen hole 602, which dislodges any plastic particles stuck inside the screen hole 602, ensuring that the screen hole 602 remains unobstructed. Toothed belts 60 are fixedly connected to both ends of the ring belt 601. 9. The inner side of the toothed belt 609 is connected to a pulley 610 that is connected to the drive shaft 603. One end of the pulley 610 away from the drive shaft 603 is fixedly connected to the drive motor 604. Gears 611 are fixedly connected to the surfaces of the two crushing wheels 606. The two gears 611 are meshed together. A sprocket 612 is fixedly connected to the surface of one crushing wheel 606 and the output shaft of the drive motor 604. A chain 613 is meshed with the other sprocket 612 on the surface of one sprocket 612.

[0036] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12The intermittent feeding mechanism 8 shown includes a hydraulic cylinder 801 fixedly connected to the end of the feeding tank 5 away from the servo motor 702. An adjusting frame 802 is fixedly connected to the output shaft of the hydraulic cylinder 801. Both ends of the adjusting frame 802 penetrate the feeding tank 5 and respectively extend into the processing chamber 504 and the discharge chamber 502. A feeding hopper 803, slidably connected to the processing chamber 504, is fixedly connected to the upward-facing end of the adjusting frame 802. The feeding hopper 803 is positioned above the ring belt 601. A guide plate 804, slidably connected to the discharge chamber 502, is fixedly connected to the downward-facing end of the adjusting frame 802. The upper end of the guide plate 804 has a guide opening 805 communicating with the adjacent discharge pipe 711. {During normal production of the rain boots, the hydraulic cylinder 801 reciprocates according to a preset program. The hydraulic cylinder 801 drives the adjusting frame 802 to reciprocate, and the adjusting frame 802 simultaneously drives the feeding hopper 803 and the guide plate 804 to reciprocate.} 803 guides the plastic granules along the way to different positions on the ring belt 601 to prevent the plastic granules from concentrating in one of the first guide hoppers 607, reducing the cleaning burden on the subsequent cleaning mechanism 7. At the same time, the guide plate 804 drives the guide port 805 to move back and forth. When the guide port 805 is connected to a certain discharge pipe 711, the plastic granules in the discharge pipe 711 can fall normally into the discharge chamber 502. This can avoid the probability of the discharge chamber 502 being blocked due to excessive discharge of plastic granules. The inside of the guide tank 5 is provided with a guide groove 505 that communicates with the processing chamber 504. The surface of the feed hopper 803 is fixedly connected to a slide plate 806 that is slidably connected to the guide groove 505. The guide plate 804 is fixedly connected to two sides parallel to the servo motor 702 with slide bars 807. The surface of the slide bars 807 is slidably connected to a slide frame 808 that is fixedly connected to the discharge chamber 502.

[0037] In use, when the operator sucks plastic granules into the guide tank 5 using a vacuum feeder, the hydraulic cylinder 801 drives the feed hopper 803 to move back and forth. The feed hopper 803 guides the plastic granules to different positions on the belt 601. The screening holes 602 on the surface of the belt 601 screen the passing plastic granules, filtering out those with a diameter larger than the screening holes 602. The plastic granules that successfully pass through the screening holes 602 are fed into the corresponding first guide hopper 607. The first guide hopper 607 guides these plastic granules into the conductive roller 701 connected to it. At the same time, the drive motor 604 drives the connected transmission shaft 603 to rotate. The transmission shaft 603 drives the belt 601 to move. The belt 601 moves the plastic granules that did not successfully pass through the screening holes 602 through the screening holes 602. When the plastic granules inside the screen hole 602 are flipped downwards by the ring belt 601, they fall into the discharge hopper 605 under the action of gravity. The discharge hopper 605 guides the plastic granules between the two crushing wheels 606. At this time, the drive motor 604 drives the sprocket 612 connected to it to rotate. The sprocket 612 drives the chain 613 to rotate. The chain 613 drives another sprocket 612 to rotate. The other sprocket 612 drives the gear 611 connected to it to rotate. The gear 611 drives another gear 611 to rotate in opposite directions. At this time, the two gears 611 drive the two crushing wheels 606 to rotate in opposite directions, so that the two crushing wheels 606 crush the plastic granules in opposite directions. The crushed plastic granules enter the second guide hopper 608 along the discharge hopper 605. The second guide hopper 608 guides the crushed plastic granules into the connected conductive roller 701.

[0038] When the plastic granules enter the conductive roller 701, the servo motor 702 drives the worm gear 703 to rotate, which in turn drives all the worm wheels 704 to rotate. The worm wheels 704 then drive the conductive roller 701 to rotate, causing the conductive roller 701 to continuously tumble the plastic granules inside. The static electricity on the surface of these plastic granules is quickly conducted away by the conductive roller 701 upon contact. At this point, dust loses its static attraction and quickly separates from the plastic granules. Simultaneously, the air pump 706 rapidly draws gas into the first gas distributor 707, which then rapidly and evenly distributes the gas into all the second gas distributors 708. The second gas distributors 708 then evenly distribute the gas into the connected high-pressure nozzles 709, which then rapidly guide the gas through the conductive roller 701. The gas enters the interior of the conductive roller 701 through the upward-facing dust guide hole 705. As the gas passes through the conductive roller 701, it carries away the surrounding dust and exits the conductive roller 701 through the downward-facing dust guide hole 705. During the downward flow of the gas, the dust filter 710 can filter out the dust carried in the gas, ensuring that the air discharged from the cleaning chamber 501 remains clean. Then, the plastic particles that have detached from the conductive roller 701 are guided into the discharge chamber 502 by the discharge pipe 711. The discharge chamber 502 guides the clean and uniformly sized plastic particles into the injection molding system 2. This not only reduces the difficulty of melting the plastic particles in the injection molding system 2, but also makes the injection molding system 2 perform injection work more easily, reducing the injection resistance of the injection molding system 2 caused by dust, and reducing the burden on the staff to clean the injection molding system 2 afterwards.

[0039] It should be noted that the injection molding system 2, control system 3, drive motor 604, servo motor 702, air pump 706, and hydraulic cylinder 801 mentioned above are all components with relatively mature existing technology.
