Description

Technical Field

[0001] This utility model relates to the field of injection molding machine material discharge protection technology, specifically to an injection molding machine material discharge protection device. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] Publication number CN222792609U discloses a material discharge protection device for injection molding machines. This device, through the design of a baffle cloth, can prevent material from falling off the conveyor belt, and the height of the baffle cloth can be adjusted to improve the protective effect. However, during use, this device cannot effectively slow down the falling speed of the injection-molded product. When the injection-molded product falls onto the conveyor belt surface, it will bear the force of its own weight and the force applied by the conveyor belt, easily leading to surface cracking or even damage. Therefore, we propose a material discharge protection device for injection molding machines. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a material discharge protection device for injection molding machines.

[0005] The technical solution adopted by this utility model to solve its technical problem is a material discharge protection device for injection molding machines, including a material discharge frame. The top center of the material discharge frame has an integrated material inlet. The inside of the material inlet is provided with a guide slide. A plurality of first adjustment brackets are assembled on one side of the inside of the material discharge frame. An adjustment roller is assembled on the end of each first adjustment bracket away from the material discharge frame. A stepper motor is assembled on the side wall of the adjustment roller and the outer wall of the first adjustment bracket. A buffer plate is provided on the side of the adjustment roller away from the first adjustment bracket.

[0006] The unloading rack is fixedly connected to the top of one side of the fixed base. An adjusting motor is mounted on the side wall of the fixed base away from the unloading rack. A coupling is mounted on the power output end of the adjusting motor. A transmission rod is mounted on the end of the coupling away from the adjusting motor. A transmission gear is integrally constructed on the outer periphery of the transmission rod. A synchronous half gear meshes with the side wall of the transmission gear. The synchronous half gear is integrally constructed on the side wall of the synchronous roller. A guide plate is fixedly connected to the end of the connecting shaft away from the synchronous half gear.

[0007] By adopting the above technical solution, when the injection molded product is first conveyed to the surface of the conveyor belt through the inlet, the injection molded product falls into the interior of the unloading rack through the guide slide, and passes through the buffer of multiple first and second adjusting brackets in sequence. It first falls onto the surface of the buffer plate. The buffer plates on the side walls of the first and second adjusting brackets are rotated by stepper motors at a certain angle, and then the adjusting rollers are adjusted by a certain angle as the stepper motors rotate to adapt to injection molded products of different volumes and prevent the injection molded products from getting stuck inside.

[0008] When the injection-molded finished product is conveyed through the conveyor belt to the guide plate, the transmission rod connected to the coupling is driven to rotate by adjusting the motor operation. The transmission gear set on the outer periphery of the transmission rod drives the meshing synchronous half gear to rotate. The synchronous roller rotates with the transmission of the synchronous half gear and rotates around the connecting shaft in the unloading frame on both sides as the axis, deflecting at a certain angle, thereby driving the guide plate to complete the angle adjustment to control the material output.

[0009] Specifically, the fixed base is equipped with a conveyor belt driven by a motor.

[0010] By adopting the above technical solution, the injection-molded finished product is transported to the placement area via a conveyor belt.

[0011] Specifically, the surface of the fixed base is integrally constructed with a baffle on one side of the unloading rack.

[0012] By adopting the above technical solution, baffles are used to prevent injection-molded products from popping out when they fall onto the conveyor belt surface.

[0013] Specifically, the inner end of the unloading rack away from the first adjusting bracket is equipped with a second adjusting bracket that matches its structure, and the buffer plate surface installed on the side wall of the first and second adjusting brackets is provided with a buffer pad.

[0014] By adopting the above technical solution, the falling speed of the injection molded product is reduced by the buffer plates and buffer pads installed on the side walls of multiple first and second supports, thereby avoiding cracks or even damage to the injection molded product due to direct falling on the conveyor belt surface.

[0015] Specifically, the two ends of the synchronous roller are respectively equipped with connecting shafts, and the connecting shafts are rotatably connected to the inner wall of the fixed base.

[0016] By adopting the above technical solution, the synchronous roller can rotate around the connecting shaft as the angle is adjusted when the adjustment motor is running, thus adjusting the angle.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The technical solution of this application firstly involves conveying the injection-molded finished product to the surface of the conveyor belt through the inlet. The injection-molded finished product falls into the interior of the unloading rack through the guide slide, and then passes through the buffer of multiple first and second adjusting brackets in sequence. It first falls onto the surface of the buffer plate. The buffer plates on the side walls of the first and second adjusting brackets are rotated by stepper motors at a certain angle. Then, the adjusting rollers are adjusted by a certain angle as the stepper motors rotate to adapt to injection-molded finished products of different volumes and prevent the injection-molded finished products from getting stuck inside.

[0019] When the injection-molded finished product is conveyed through the conveyor belt to the guide plate, the transmission rod connected to the coupling is driven to rotate by adjusting the motor operation. The transmission gear set on the outer periphery of the transmission rod drives the meshing synchronous half gear to rotate. The synchronous roller rotates with the transmission of the synchronous half gear and rotates around the connecting shaft in the unloading frame on both sides as the axis, deflecting at a certain angle, thereby driving the guide plate to complete the angle adjustment to control the material output.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-3This utility model provides a technical solution: a material feeding protection device for an injection molding machine, including a feeding frame 1. The feeding frame 1 has an integrated feeding port 2 at the top center. A guide slide 3 is provided through the inside of the feeding port 2. A plurality of first adjusting brackets 4 are assembled on one side of the inside of the feeding frame 1. An adjusting roller 5 is assembled on the end of each first adjusting bracket 4 away from the feeding frame 1. A stepper motor 6 is assembled on the side wall of the adjusting roller 5 and the outer wall of the first adjusting bracket 4. A buffer plate 7 is provided on the side of the adjusting roller 5 away from the first adjusting bracket 4.

[0027] The unloading rack 1 is fixedly connected to the top of one side of the fixed base 10. An adjusting motor 13 is mounted on the side wall of the fixed base 10 away from the unloading rack 1. A coupling 14 is mounted on the power output end of the adjusting motor 13. A transmission rod 15 is mounted on the end of the coupling 14 away from the adjusting motor 13. A transmission gear 16 is integrally constructed on the outer periphery of the transmission rod 15. A synchronous half gear 17 meshes with the side wall of the transmission gear 16. The synchronous half gear 17 is integrally constructed on the side wall of the synchronous roller 18. A guide plate 20 is fixedly connected to the end of the connecting shaft 19 away from the synchronous half gear 17.

[0028] In use, when the injection molded product is first conveyed to the surface of the conveyor belt 11 through the feed port 2, the injection molded product falls into the interior of the unloading rack 1 through the guide slide 3, and passes through multiple first adjusting brackets 4 and second adjusting brackets 8 in sequence. It first falls onto the surface of the buffer plate 7. The buffer plate 7 on the side wall of the first adjusting bracket 4 and the second adjusting bracket 8 is rotated by the stepper motor 6 at a certain angle. Then, the adjusting roller 5 is adjusted by a certain angle as the stepper motor 6 rotates to adapt to injection molded products of different volumes and prevent the injection molded product from getting stuck inside.

[0029] When the injection-molded finished product is conveyed through the conveyor belt 11 to the guide plate 20, the transmission rod 15 connected to the coupling 14 is driven to rotate by the operation of the motor 13. The transmission gear 16 set on the outer periphery of the transmission rod 15 drives the meshing synchronous half gear 17 to rotate. The synchronous roller 18 rotates with the transmission of the synchronous half gear 17, with the connecting shaft 19 rotating on both sides in the unloading frame 1 as the axis, and deflects at a certain angle, thereby driving the guide plate 20 to complete the angle adjustment to control the material output.

[0030] As shown in the figure, the fixed base 10 is equipped with a conveyor belt 11 driven by a motor.

[0031] In use, the injection-molded finished product is transported to the placement area via conveyor belt 11.

[0032] As shown in the figure, the surface of the fixed base 10 is integrally constructed with a baffle 12 on one side of the unloading rack 1.

[0033] During use, the baffle 12 is used to prevent the injection molded product from popping out when it falls onto the surface of the conveyor belt 11.

[0034] As shown in the figure, the end of the unloading rack 1 that is away from the first adjusting bracket 4 is equipped with a second adjusting bracket 8 that fits its structure. The buffer plate 7 installed on the side wall of the first adjusting bracket 4 and the second adjusting bracket 8 is provided with a buffer pad 9.

[0035] During use, the drop speed of the injection molded product is reduced by the buffer plates 7 and buffer pads 9 installed on the side walls of multiple first and second supports, thereby preventing the injection molded product from cracking or even being damaged due to falling directly onto the surface of the conveyor belt 11.

[0036] As shown in the figure, the two ends of the synchronous roller 18 are respectively equipped with connecting shafts 19, and the connecting shafts 19 are rotatably connected to the inner wall of the fixed base 10.

[0037] In use, the synchronous roller 18 can be adjusted in angle by connecting the rotating shaft 19 so that it can rotate around the axis of the adjusting motor 13.

[0038] The working principle and usage process of this utility model are as follows: First, when the injection-molded product is conveyed to the surface of the conveyor belt 11 through the feed inlet 2, the injection-molded product falls into the interior of the unloading rack 1 through the guide slide 3. It then passes through the buffers of multiple first adjusting brackets 4 and second adjusting brackets 8, and first falls onto the surface of the buffer plate 7. The buffer plates 7 and buffer pads 9 installed on the side walls of the multiple first and second brackets reduce the falling speed of the injection-molded product, thereby preventing the injection-molded product from cracking or even being damaged due to directly falling onto the surface of the conveyor belt 11. The buffer plates 7 on the side walls of the first adjusting brackets 4 and the second adjusting brackets 8 are rotated at a certain angle by the stepper motor 6. The angle is adjusted by the adjusting roller 5 as the stepper motor 6 rotates to accommodate injection molded products of different volumes, preventing the injection molded products from getting stuck inside. When the injection molded product passes through the conveyor belt 11 and is transported to the guide plate 20, the adjusting motor 13 drives the transmission rod 15 connected to the coupling 14 to rotate. The transmission gear 16 set on the outer periphery of the transmission rod 15 drives the meshing synchronous half gear 17 to rotate. The synchronous roller 18 rotates with the synchronous half gear 17, with the connecting shaft 19 rotating on both sides in the unloading frame 1 as the axis, deflecting at a certain angle, thereby driving the guide plate 20 to complete the angle adjustment to control the material output.
