Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a defective product recycling device for toy production. Background Technology

[0002] Injection molding machines are the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. In the toy manufacturing process, the plastic parts molded by the injection molding machine need to undergo quality inspection. The injection molding machine is used to detect the amount of plastic injected and compare it with the set injection amount. Products exceeding the range are judged as defective products. Defective products fall out of the mold and slide into a defective product recycling device for recycling, while qualified products are picked up by a robotic arm.

[0003] However, most of the existing defective product recycling devices for toy production on the market require staff to judge whether the collection box is full of defective products. This requires staff to keep a close eye on the situation in the collection box, which increases the labor intensity and mental burden on workers. Moreover, if staff are negligent or fail to notice in time, the overflowing defective products are very likely to scatter on the ground, causing chaos on site, which is quite inconvenient.

[0004] Therefore, those skilled in the art have provided a defective product recycling device for toy production to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a defective product recycling device for toy production. This device detects overflow by using an infrared emitting and receiving component in the action mechanism, triggering an alarm. A servo motor drives the rotating base plate to change the collection frame, achieving automatic switching and alarm without stopping the machine, reducing labor intensity and ensuring continuous production.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A defective product recycling device for toy production includes an injection molding machine body, a robotic arm assembly mounted on the upper end of the injection molding machine body, and a base frame fixedly connected to the lower end of the injection molding machine body. The robotic arm assembly is used to remove good products from the mold of the injection molding machine body and place them in a designated position. An actuation mechanism is provided on the upper end of the base frame. The actuation mechanism includes a rotating base plate, two collection frames, an infrared emitting component, and an infrared receiving component. A servo motor is installed in the cavity at the front end of the base frame. The output shaft of the servo motor passes through the base frame and is fixedly connected to the rotating base plate. A partition is fixedly connected to the middle of the upper end of the rotating base plate. Connecting blocks are fixedly connected to the front and rear ends of both sides of the upper end of the rotating base plate. The collection frames are all located on the rotating base plate and are separated by the partition. Connecting grooves are provided on both sides of the lower end of the collection frames. The connecting blocks are slidably connected to the connecting grooves. An alarm bell is provided at the lower end of the outer wall of the front end of the injection molding machine body.

[0008] The above technical solution detects the overflow of the collection box using infrared transmitting and receiving components, and triggers an alarm when it overflows. A servo motor drives the rotating base plate to switch the positions of the two collection boxes, achieving automatic switching and alarm without stopping the machine, reducing labor intensity and ensuring production continuity.

[0009] Furthermore, the infrared emitting component and the infrared receiving component are respectively fixed to the inner wall of the base frame opposite to the outer wall of the rotating base plate by bolts;

[0010] The above technical solution allows for easy installation and fixation of the infrared emitting and receiving components to the base frame using bolts, ensuring that the infrared emitting and receiving components can accurately align.

[0011] Furthermore, a discharge hopper is fixedly connected to the discharge channel at the lower end of the injection molding machine body, and the discharge direction of the discharge hopper corresponds to the collection frame at the rear end;

[0012] The above technical solution uses a fixedly connected discharge hopper to guide the defective products, ensuring they fall accurately into the corresponding collection box below and preventing them from scattering outside the collection box.

[0013] Furthermore, elastic sheets are fixedly connected to the openings at the front and rear ends of the rotating base plate, and a stop block is fixedly connected to the upper end of each elastic sheet. The stop block is snapped into the collection frame.

[0014] Through the above technical solution, the elastic sheet fixedly connected to the rotating base plate can use its elasticity to block the collection frame, ensuring the stability of the collection frame during the rotation of the rotating base plate, preventing the collection frame from slipping due to centrifugal force, and at the same time facilitating manual pressing of the block to unlock and remove the collection frame.

[0015] Furthermore, sliding grooves are provided on both sides of the front end of the upper middle part of the base frame. A return spring is fixedly connected to the bottom surface inside the sliding groove. A positioning block is fixedly connected to the upper end of the return spring. The upper end of the positioning block passes through the base frame and is engaged with the rotating base plate.

[0016] Through the above technical solution, the return spring inside the chute utilizes its elasticity to ensure that when the rotating base plate rotates to the position where the collection frame is aligned with the discharge hopper, the positioning block pops out under the action of the return spring and engages with the rotating base plate, thus playing a positioning role and ensuring the accuracy of material reception in the collection frame.

[0017] Furthermore, all the positioning blocks slide inside the slide groove, and the part of the positioning block that engages with the rotating base plate is spherical;

[0018] By designing the upper end of the positioning block into a spherical shape, the frictional resistance between the positioning block and the rotating base plate can be reduced, allowing the rotating base plate to smoothly push the positioning block open when rotating, and also to smoothly engage when rotating to the corresponding position.

[0019] Furthermore, a PLC control panel is provided on the upper end of the outer wall of the front end of the injection molding machine body. The PLC control panel is electrically connected to the robotic arm assembly, servo motor, infrared emitting assembly, infrared receiving assembly, and alarm bell.

[0020] Through the above technical solution, the PLC control panel set on the injection molding machine body serves as the core control unit. It can receive detection signals from the infrared emitting and receiving components, and automatically control the coordinated actions of the servo motor and alarm bell. It also allows the operator to control the operating status of the robotic arm components, thereby realizing the automated operation of the device.

[0021] This utility model has the following beneficial effects:

[0022] 1. The present invention proposes a defective product recycling device for toy production. The device uses an infrared emitting component and an infrared receiving component in the action mechanism to detect the extent of defective products inside. When the device is full, an alarm is triggered to notify the staff. This eliminates the need for staff to constantly pay attention to the status of the collection box, reducing the labor intensity and mental burden on workers and preventing the accumulation or scattering of defective products due to negligence.

[0023] 2. The present invention proposes a defective product recycling device for toy production. The device uses a one-in-one standby working mode with two collection boxes in the action mechanism. When the box is full, the servo motor drives the rotating base plate to rotate, and the standby collection box is swapped with the full collection box. This eliminates the need to stop the machine and wait for manual replacement of the collection boxes, thus avoiding equipment downtime and maintaining the continuity of production.

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

[0033] Reference Figure 1-6 This utility model provides a specific implementation method:

[0034] A defective product recycling device for toy production includes an injection molding machine body 1, a robotic arm assembly 2, a PLC control panel 3, a base frame 4, and an action mechanism 5 mounted on the upper end of the base frame 4.

[0035] Under the control of the PLC control panel 3, the robotic arm assembly 2 continuously removes the molded good products from the mold and transfers them to a designated location. Simultaneously, defective products are judged to be substandard and fall naturally through the discharge channel at the lower end of the injection molding machine body 1. To prevent defective products from scattering, a discharge hopper 510 is fixedly connected to the discharge channel. Defective products follow the guide of the discharge hopper 510 and fall into the collection frame 505 located directly below it, which is in operation. It is worth noting that the PLC control panel is the controller.

[0036] To facilitate the convenient installation and secure fixation of the collection frame 505, two sets of connecting blocks 504 are fixed to the upper end of the rotating base plate 502. When installing the collection frame 505, align the connecting groove 506 at its bottom with the connecting block 504 and push it inward. During the pushing process, the elastic piece 6 fixed at the opening of the rotating base plate 502 deforms under force. After the collection frame 505 is fully pushed into place, the elastic piece 6 returns to its original shape and drives the stop block 7 at its upper end to automatically lock the collection frame 505, thereby restricting it on the rotating base plate 502 and preventing slippage during subsequent movement.

[0037] As defective products continuously fall into the collection box 505, its internal accumulation height gradually increases. Infrared emitting component 507 and infrared receiving component 508, fixed to the base frame 4 and positioned opposite each other, perform real-time beam detection. When the defective products in the collection box 505 accumulate to a level that blocks the infrared light, the infrared receiving component 508 transmits the blocking signal to the PLC control panel 3. Upon receiving this signal, the PLC control panel 3 controls the alarm bell 509 on the injection molding machine body 1 to sound an alarm, alerting on-site personnel. This eliminates the need for constant manual monitoring, reducing the workload of staff. The PLC control panel 3 can be programmed with a "delay confirmation" function. Only when the infrared light is continuously blocked for a set time will the machine be considered full and the alarm triggered. Instantaneous material passing through will be filtered as invalid signals by the system, avoiding misjudgments.

[0038] At the same moment the alarm is issued, the PLC control panel 3 outputs an action command to the servo motor 501 inside the base frame 4. The servo motor 501 starts and drives the rotating base plate 502 to rotate. During the rotation of the rotating base plate 502, its bottom surface presses against the positioning blocks 10 on both sides of the base frame 4. Since the end of the positioning block 10 that contacts the rotating base plate 502 is spherical, the rotating base plate 502 can smoothly press the positioning block 10 into the slide groove 8 and compress the return spring 9, thereby avoiding jamming. When the rotating base plate 502 rotates precisely 180 degrees, the collection box 505, which was originally full of defective products, is moved away from directly below the discharge hopper 510, while another empty collection box 505, which was in a "standby state", is switched to the receiving position. At this point, the compressed return spring 9 releases its elastic force, pushing the positioning block 10 upwards and re-engaging it into the rotating base plate 502, thus rigidly positioning the rotating base plate 502 and ensuring that the empty collection frame 505 is aligned with the discharge hopper 510, improving the accuracy of subsequent material receiving. The entire switching process is rapid, and the injection molding machine does not need to stop and wait, ensuring the continuity of production.

[0039] While the equipment continues to feed defective products into the new empty collection box 505 without stopping, the operator can calmly approach the fully loaded collection box 505 that has been transferred out. The operator manually moves the stop block 7 downwards to deform the elastic piece 6 and release its locking mechanism. Then, the operator pulls the collection box 505 outwards, allowing it to disengage from the connecting block 504 through the connecting groove 506. The fully loaded collection box 505 can then be easily removed for emptying and cleaning. After cleaning, the empty box is pushed back into its locking position in the same way, putting it back into standby mode for the next automatic switching cycle. The elastic piece 6 can be made of spring steel.

[0040] Working principle: When using this defective product recycling device for toy production, the robotic arm assembly 2, under the control of the PLC control panel 3, removes the good products from the injection mold, while the defective products fall through the discharge channel inside the injection molding machine body 1 and are guided by the discharge hopper 510 into the collection frame 505 located directly below it in working condition. The infrared emitting assembly 507 and the infrared receiving assembly 508 maintain real-time beam detection of the fullness of the collection frame 505 and transmit the detection signal to the PLC control panel 3. After the PLC control panel 3 receives the signal obstruction signal, it controls the alarm bell 509 to issue an audible and visual alarm, reminding the on-site staff that the collection frame 505 is full. At the same time, the PLC control panel 3 starts the servo motor 501 to drive the rotating base plate 502 to rotate, switching the empty collection frame 505 to the receiving position. The staff can manually press the stop block 7 to release the jamming restriction on the full collection frame 505 and remove it. After emptying the defective products inside, it is fixed back to the rotating base plate 502, putting it into standby state, waiting for the next replacement cycle.
