Description

Technical Field

[0001] This utility model relates to the field of injection molding machine processing technology, and in particular to an injection molding machine waste recycling device. Background Technology

[0002] Washing machines require many injection-molded components for assembly during the manufacturing process. These components are typically produced by injection molding machines, which generate a certain amount of waste during the injection molding process.

[0003] Chinese Patent No. CN220808269U discloses a waste recycling device for injection molding machines, comprising: a base, a housing, and a screen. The housing is located on the upper surface of the base, with an impurity outlet at the lower front of the housing and a waste outlet below the impurity outlet. By setting up a screen, baffle one, baffle two, and baffle three, the rotation of the motor drives the screen to rotate via a rotating shaft, thereby allowing the incoming material to be screened through the screen holes on the upper surface of the screen. The injection molding machine waste enters the waste channel between baffle one and baffle two and is discharged through the waste outlet. Fine impurities fall through the screen holes into the impurity channel between baffle two and baffle three and are finally discharged through the impurity outlet, thus completing the screening of the incoming material.

[0004] However, in the current injection molding process, the ejector cylinder usually drives the ejector rod to push the product out of the mold. After long-term use, this method can easily cause friction between the ejector rod and the mold plate, resulting in ejection marks. This affects the surface finish of the product and increases the scrap rate. At the same time, because the ejector rod has a small diameter, it is easy to break or bend due to insufficient compressive strength, and the ejector rod needs to be replaced regularly. Utility Model Content

[0005] Based on the aforementioned technical problems, this utility model proposes a waste recycling device for injection molding machines.

[0006] This utility model proposes an injection molding machine waste recycling device, including an injection molding machine body, an outlet is provided inside the injection molding machine body, a waste bin is placed inside the injection molding machine body and located below the outlet, and a telescopic transport mechanism is provided inside the injection molding machine body.

[0007] The telescopic transport mechanism includes a conveyor, one end of which extends to the outer surface of the injection molding machine body. Concave support plates are provided on opposite sides of the side plates of the conveyor. A drive motor is fixedly installed on one side of one of the concave support plates. Drive rollers are symmetrically installed between the two concave support plates via bearings. A conveyor belt is connected to the surface of the drive rollers via a pulley drive. One end of the output shaft of the drive motor is fixedly sleeved to one end of one of the drive rollers via a coupling.

[0008] Preferably, a bracket is fixedly installed on the upper surface of the injection molding machine body, a first self-driving slide rail is fixedly installed on the upper surface of the bracket, a support plate is fixedly connected to the upper surface of the slider of the first self-driving slide rail, a second self-driving slide rail is provided on the upper surface of the support plate, a telescopic cylinder is fixedly installed on the upper surface of the second self-driving slide rail, a connecting rod is fixedly connected to one end of the piston rod of the telescopic cylinder, and a flexible gripper plate is provided at one end of the connecting rod.

[0009] Through the above technical solution, multiple flexible grippers are arranged in a rectangular array on the surface of the flexible gripper disc, which makes it easy for the flexible grippers to contact and grip the injection molding auxiliary parts and waste materials on the moving template inside the injection molding machine. The cooperation of the second self-driven slide rail and the telescopic cylinder makes it easy to remove the injection molding auxiliary parts and waste materials from the moving template inside the injection molding machine. At the same time, when the flexible grippers need to be maintained, the cooperation of the first self-driven slide rail, the second self-driven slide rail and the telescopic cylinder drives the flexible gripper disc to leave the injection molding machine.

[0010] Preferably, the telescopic transport mechanism includes a chute extending through the surface of the conveyor side plate, the surface of the drive roller is slidably connected to the inner wall of the chute, and a push cylinder is fixedly installed on the opposite side surface of the conveyor side plate, with one end of the piston rod of each of the two push cylinders fixedly connected to one side surface of each of the two concave support plates.

[0011] The above technical solution drives the cylinder piston rod to extend and retract, which in turn moves the concave support plate connected to it. The movement of the concave support plate causes the drive roller connected to it to move along the inner wall of the slide groove, thereby driving the conveyor belt to move.

[0012] Preferably, guide rails are fixedly installed on opposite sides of the conveyor side plate, and two moving blocks are slidably engaged on the surfaces of the two guide rails, with the surfaces of the moving blocks being fixedly connected to the surfaces of the concave support plate.

[0013] The above technical solution drives the cylinder piston rod to extend and retract, which in turn moves the concave support plate connected to it. The movement of the concave support plate causes the moving block to move along the guide rail surface, thereby making the concave support plate move smoothly.

[0014] Preferably, the waste bin has a perforation on the side surface near the conveyor, the side plate surface of the conveyor slides in contact with the inner wall of the perforation, and a collection box is provided on one outer surface of the injection molding machine body, the collection box being located below the conveyor extending out of the injection molding machine body.

[0015] The above technical solution allows the perforation to facilitate the conveyor belt entering the waste bin, so that the injection molded parts fall onto the conveyor belt through the discharge port, and are then transported to the collection bin by the conveyor.

[0016] Preferably, a weight sensor is embedded in the lower surface of both the waste bin and the collection bin. The weight sensor is electrically connected to an alarm via a signal processing module. The alarm is installed on the upper surface of the controller of the injection molding machine.

[0017] Through the above technical solution, the waste bin and collection bin collect waste materials and injection molded parts generated during the injection molding process. As the material in the bin increases, the weight sensor detects the change in weight and converts this change into an electrical signal output. The electrical signal is transmitted to the signal processing module, which processes and analyzes the signal. When the weight in the bin reaches or exceeds the preset alarm threshold, the signal processing module sends a signal to the alarm. After receiving the signal, the alarm sounds an alarm to remind the operator that the bin is full or has reached the predetermined weight and needs to be cleaned or processed.

[0018] The beneficial effects of this utility model are as follows:

[0019] By setting up a telescopic transport mechanism, the piston rod of the push cylinder is extended and retracted to drive the conveyor belt to move, which facilitates the entry of injection molded parts and waste into the collection box and waste box respectively, so as to achieve the effect of recycling waste. At the same time, the drive roller and drive motor are installed by using a concave support plate to facilitate the rotation of the conveyor belt, thereby achieving the effect of transporting injection molded parts.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-7 An injection molding machine waste recycling device includes an injection molding machine body 1, an outlet 2 is provided inside the injection molding machine body 1, a waste bin 3 is placed inside the injection molding machine body 1, the waste bin 3 is located below the outlet 2, and a telescopic transport mechanism is provided inside the injection molding machine body 1.

[0030] To remove the injection mold and waste material from the moving template inside the injection molding machine body 1, a bracket 5 is fixedly installed on the upper surface of the injection molding machine body 1. A first self-driven slide rail 6 is fixedly installed on the upper surface of the bracket 5. A support plate 7 is fixedly connected to the upper surface of the slider of the first self-driven slide rail 6. A second self-driven slide rail 8 is provided on the upper surface of the support plate 7. A telescopic cylinder 9 is fixedly installed on the upper surface of the second self-driven slide rail 8. A connecting rod 10 is fixedly connected to one end of the piston rod of the telescopic cylinder 9. A flexible gripper plate is provided at one end of the connecting rod 10. 11. The surface of the flexible gripper disk 11 is arranged in a rectangular array with multiple flexible grippers, which makes it easy for the flexible grippers to contact and grip the injection molded parts and waste materials on the moving template inside the injection molding machine body 1. The interaction between the second self-driven slide rail 8 and the telescopic cylinder 9 makes it easy to remove the injection molded parts and waste materials from the moving template inside the injection molding machine body 1. At the same time, when the flexible grippers need to be maintained, the interaction between the first self-driven slide rail 6, the second self-driven slide rail 8 and the telescopic cylinder 9 drives the flexible gripper disk 11 to leave the injection molding machine body 1.

[0031] To collect injection molding accessories and waste materials separately, the telescopic transport mechanism includes a conveyor 4. One end of the conveyor 4 extends to the outer surface of the injection molding machine body 1. Concave support plates 41 are provided on opposite sides of the side plates of the conveyor 4. A drive motor 42 is fixedly installed on one side of one of the concave support plates 41. Drive rollers 43 are symmetrically installed between the two concave support plates 41 through bearings. A conveyor belt 44 is connected to the surface of the drive rollers 43 through a pulley drive. One end of the output shaft of the drive motor 42 is fixedly sleeved to one end of one of the drive rollers 43 through a coupling. The rotation of the output shaft of the drive motor 42 drives the drive roller 43 connected to it to rotate. The rotation of the drive roller 43 drives the conveyor belt 44 to rotate through the pulley, thereby driving the other drive roller 43 to rotate, thus facilitating the transport of injection molding accessories.

[0032] To move the conveyor belt 44 below the discharge port 2, the telescopic transport mechanism includes a chute 45 extending through the surface of the side plate of the conveyor 4. The surface of the drive roller 43 is slidably connected to the inner wall of the chute 45. Simultaneously, a push cylinder 46 is fixedly installed on the opposite side surface of the conveyor 4. One end of the piston rod of each of the two push cylinders 46 is fixedly connected to one side surface of each of the two concave support plates 41. Guide rails 47 are fixedly installed on the opposite side surface of the conveyor 4. Two moving blocks 48 are slidably engaged with the surfaces of the two guide rails 47. The surfaces of the moving blocks 48 are fixedly connected to the surfaces of the concave support plates 41. A perforation 49 is provided on the side surface of the waste bin 3 closest to the conveyor 4. The surface of the side plate of the conveyor 4 is connected to the... The inner wall of the perforation 49 slides in contact. A collection box 410 is provided on one outer surface of the injection molding machine body 1. The collection box 410 is located below the conveyor 4 extending outside the injection molding machine body 1. By pushing the piston rod of the cylinder 46 to extend, it drives the concave support plate 41 connected to it to move. The movement of the concave support plate 41 drives the moving block 48 to move along the surface of the guide rail 47, so that the concave support plate 41 moves smoothly. At the same time, the movement of the concave support plate 41 drives the drive roller 43 connected to it to move along the inner wall of the slide groove 45, thereby driving the conveyor belt 44 to enter the waste box 3 through the perforation 49, so that the injection molding auxiliary parts can fall onto the conveyor belt 44 through the discharge port 2, and be transported to the collection box 410 by the conveyor belt 44 and the conveyor 4.

[0033] To clean the collection bin 410 and waste bin 3, weight sensors 411 are embedded on the lower surface of both the waste bin 3 and the collection bin 410. The weight sensors 411 are electrically connected to an alarm 412 via a signal processing module. The alarm 412 is installed on the upper surface of the controller of the injection molding machine body 1. The waste bin 3 and the collection bin 410 collect waste materials and injection molding accessories generated during the injection molding process. As the material in the waste bin 3 and the collection bin 410 increases, the weight sensors 411 sense the change in weight and convert this change into an electrical signal output. The electrical signal is transmitted to the signal processing module, which processes and analyzes the signal. When the weight in the waste bin 3 and the collection bin 410 exceeds a preset alarm threshold, the signal processing module sends a signal to the alarm 412. After receiving the signal, the alarm 412 sounds an alarm to remind the operator that the waste bin 3 and the collection bin 410 have reached the predetermined weight and need to be processed.

[0034] By setting up a telescopic transport mechanism, the piston rod of the push cylinder 46 is extended and retracted to drive the conveyor belt 44 to move, so that the injection molded parts and waste materials can be put into the collection box 410 and the waste box 3 respectively, thus achieving the effect of recycling waste materials. At the same time, the drive roller 43 and the drive motor 42 are installed on the concave support plate 41, which facilitates the rotation of the conveyor belt 44, thereby achieving the effect of transporting the injection molded parts.

[0035] Working principle: During use, after the auxiliary parts in the injection molding machine body 1 are injection molded, the injection auxiliary parts and waste materials on the moving template in the injection molding machine body 1 are removed in sequence through the cooperation of the second self-driven slide rail 8 and the telescopic cylinder 9.

[0036] At the same time, the extension of the piston rod of the cylinder 46 drives the concave support plate 41 connected to it to move. The movement of the concave support plate 41 drives the moving block 48 to move along the surface of the guide rail 47, so that the concave support plate 41 moves smoothly. At the same time, the movement of the concave support plate 41 drives the drive roller 43 connected to it to move along the inner wall of the slide groove 45, thereby driving the conveyor belt 44 to enter the waste bin 3 through the perforation 49, so that the conveyor belt 44 is located below the discharge port 2, so that the multiple grippers on the flexible gripper disc 11 first remove the injection molding auxiliary parts, so that the injection molding auxiliary parts fall onto the conveyor belt 44 through the discharge port 2. At the same time, the rotation of the output shaft of the drive motor 42 drives the drive roller 43 connected to it to rotate. The rotation of the drive roller 43 drives the conveyor belt 44 to rotate through the pulley, thereby driving another drive roller 43 to rotate. The rotation of the conveyor belt 44 causes the injection molding auxiliary parts to fall onto the conveyor 4, which facilitates the injection molding auxiliary parts to fall into the collection box 410.

[0037] Then, the piston rod of the cylinder 46 is pushed to retract, which drives the conveyor belt 44 to reset, so that the discharge port 2 is connected to the waste box 3, and the multiple grippers on the flexible gripper disc 11 remove the waste and make it fall into the waste box.

[0038] When the weight sensor 411 on the waste bin 3 or collection bin 410 detects a weight exceeding a preset alarm threshold, the signal processing module sends a signal to the alarm 412. Upon receiving the signal, the alarm 412 issues an alarm to remind the operator that the waste bin 3 or collection bin 410 has reached the predetermined weight and needs to be processed.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
