Description

Technical Field

[0001] This utility model relates to the field of production and conveying technology for injection molding machines, specifically to a central collection system for plastic parts used in injection molding machines. Background Technology

[0002] In the injection molding process, the collection and conveying of plastic parts is a crucial step. However, existing central collection systems for plastic parts often face a significant problem: material tends to accumulate on the conveyor belt. Specifically, after injection molding, the machine produces a large number of plastic parts that need to be collected and conveyed via a conveyor belt for subsequent processing and packaging. However, in actual production, due to the fast operating pace of injection molding machines and the large number of plastic parts produced, the conveyor belt often struggles to handle such a large volume of material, leading to material accumulation on the conveyor belt.

[0003] Accumulated material not only affects the normal operation of the conveyor belt and reduces production efficiency, but can also cause damage and deformation of plastic parts, thus affecting product quality. Furthermore, accumulated material can pose safety hazards, such as blocking conveyor channels and causing equipment malfunctions. Therefore, effectively solving the problem of material accumulation on the conveyor belt and improving the efficiency and stability of the central collection system for plastic parts in injection molding machines has become a pressing technical challenge in the current injection molding machine manufacturing industry.

[0004] Chinese Patent Publication No. CN220906331U discloses an automatic conveying device for a plastic parts production line. When a distance sensor detects a placement plate, an electric telescopic plate is in a retracted state. When a plastic part passes through a photoelectric switch, a drive motor starts, cooperating with a telescopic cylinder and a pusher plate to push the plastic part onto a lower conveyor, completing the transfer of the plastic part from the upper conveyor to the lower conveyor. This device can automatically transfer plastic parts from the upper conveyor to the lower conveyor and is compatible with plastic parts of various sizes, making it highly practical.

[0005] However, in actual use, when there is too much material on the conveyor belt, the material will accumulate on the conveyor belt. The accumulation of material will not only increase the operating load of the conveyor belt, causing the conveying speed to slow down or even stop, but may also cause quality problems such as deformation and scratches of plastic parts due to mutual squeezing. Utility Model Content

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figure 1-Figure 3 As shown, a central collection system for plastic parts for an injection molding machine includes a housing 1 and a conveyor belt 2 mounted on the housing 1. The central collection system also includes an anti-stacking mechanism 3 mounted on the housing 1 for pushing stacked materials. The anti-stacking mechanism 3 includes a mounting frame 31 and stacking blocks 32 mounted on the mounting frame 31 for stacking materials, as well as an ejection mechanism 4 mounted on the mounting frame 31 for continuing to push the materials on the stacking blocks 32. The central collection system for plastic parts for an injection molding machine also includes a lifting drive mechanism 5 mounted on the mounting frame 31 for driving the stacking blocks 32 to move up or down.

[0028] Several stacking blocks 32 are equidistantly arranged on the conveyor belt 2. When materials pass through the conveyor belt 2 and accumulate on it, they are guided to the stacking blocks 32. At this time, the materials can be piled up on the stacking blocks 32, which can prevent the materials from falling directly onto the conveyor belt 2 when they accumulate. When it is necessary to process the materials piled on the stacking blocks 32, the materials piled on the stacking blocks 32 can be pushed out by the pushing mechanism 4, which facilitates centralized processing of the materials piled on the stacking blocks 32. The materials on the conveyor belt 2 can be stored on the stacking blocks 32 and pushed out by the pushing mechanism 4 when needed, thus avoiding excessive material falling.

[0029] See Figure 3 and Figure 4 As shown, the anti-stacking mechanism 3 also includes a mating groove 33, an extension groove 34, a connecting block 35, and a guide rod 36; the mating groove 33 is formed on the mounting frame 31, and the stacking block 32 slides with the mating groove 33; the extension groove 34 is formed on the stacking block 32; the connecting block 35 is set on the stacking block 32; and the guide rod 36 is set on the connecting block 35.

[0030] The groove 33 allows the stacking block 32 to slide vertically on the mounting frame 31, thereby adjusting the distance between the stacking block 32 and the material on the conveyor belt 2. The extension groove 34 restricts the sliding of the ejection mechanism 4 within the extension groove 34, thereby ejecting the material accumulated on the stacking block 32. The connecting block 35 slides with the mounting frame 31, making the sliding of the stacking block 32 on the groove 33 more stable.

[0031] See Figure 4-Figure 6 As shown, the ejection mechanism 4 includes a sliding block 41 and a tension spring 42; the sliding block 41 is disposed on the guide rod 36, and the sliding block 41 and the guide rod 36 are in clearance fit; the tension spring 42 is disposed on the connecting block 35, and the two ends of the tension spring 42 are fixedly connected to the connecting block 35 and the sliding block 41 respectively.

[0032] When it is necessary to push the material on the stack block 32, pushing the sliding block 41 will cause the tension spring 42 to be stretched, and the guide rod 36 can make the sliding block 41 slide stably. When the tension spring 42 is stretched, the sliding block 41 is in a stretched state. When the sliding block 41 is not pushed, the tension spring 42 can pull the sliding block 41 to reset.

[0033] See Figure 6 and Figure 7 As shown, the ejection mechanism 4 includes a fixed block 43, a fixed plate 44, and an ejection plate 45; the fixed block 43 is disposed on the sliding block 41; the fixed plate 44 is disposed on the fixed block 43; the ejection plate 45 is disposed on the stacking block 32 and slides within the extension groove 34, and the ejection plate 45 is fixedly connected to the fixed plate 44, the fixed plate 44, and the sliding block 41 respectively.

[0034] When the sliding block 41 moves, the ejector plate 45 can be pushed by the fixed block 43 and the fixed plate 44. During this process, the fixed plate 44 can drive several ejector plates 45 to be pushed synchronously. When the ejector plate 45 moves, it can slide along the extension groove 34, so that several ejector plates 45 can push the material piled on the stacking block 32 synchronously. There is no need to process the material on one stacking block 32 separately, saving working time.

[0035] See Figure 6 and Figure 7 As shown, the ejection mechanism 4 also includes a docking limiting plate 46 and a docking block 47; the docking limiting plate 46 is disposed on the connecting block 35 and is fixedly connected to the connecting block 35; the docking block 47 is disposed on the docking limiting plate 46 and is clearance-fitted with the sliding block 41.

[0036] The docking limiting plate 46 is fixedly installed on the connecting block 35, so that when the connecting block 35 moves up or down in the mating groove 33 via the stacking block 32, it drives the docking limiting plate 46 and the docking block 47 to move synchronously, so that the sliding block 41, the guide rod 36 and the stacking block 32 can move up or down synchronously. The docking block 47 is set so that the sliding block 41 can slide stably through the docking block 47 when sliding, and prevents the sliding block 41 from tilting when sliding.

[0037] See Figure 8As shown, the lifting drive mechanism 5 includes a mounting frame 51, a linear drive 52, a threaded rod 53, a connecting limiting block 54, and a positioning plate 55. The mounting frame 51 is mounted on the mounting frame 31 and located above the mounting frame 31. The linear drive 52 is mounted on the mounting frame 51 and located above the conveyor belt 2. The threaded rod 53 is mounted on the output end of the linear drive 52 via a coupling. The connecting limiting block 54 is mounted on the stacking block 32 and is threadedly connected to the threaded rod 53. The positioning plate 55 is mounted on the stacking block 32.

[0038] The positioning plate 55 is used to fix two stacked blocks 32 together for synchronous lifting and lowering. When it is necessary to adjust the vertical lifting and lowering of the stacked blocks 32, the linear driver 52 is activated, which drives the threaded rod 53 to rotate. When the threaded rod 53 rotates, it drives the meshing connecting restricting block 54. Since the connecting restricting block 54 is fixedly connected to one of the stacked blocks 32, when the connecting restricting block 54 rises, it can drive several stacked blocks 32 to rise or fall synchronously, thereby realizing the position adjustment of the stacked blocks 32 to rise or fall, which can adapt to materials of different heights.

[0039] Working principle: Stacking blocks 32 are equidistantly arranged on conveyor belt 2 to support accumulated materials and prevent them from falling directly off conveyor belt 2. When materials accumulate, they fall onto stacking blocks 32. When handling accumulated materials, pushing sliding blocks 41 causes tension springs 42 to be stretched, and the springs slide stably through guide rods 36. When stretched, tension springs 42 keep sliding blocks 41 in a stretched state, and return to their original position when not pushed. When sliding blocks 41 move, multiple push-out plates 45 are pushed to move synchronously through fixing blocks 43 and fixing plates 44. The push-out plates 45 slide along the extension grooves 34, pushing the materials on stacking blocks 32 out synchronously. The docking limiting plate 46 is fixed to the connecting block 35 to ensure that when stacking blocks 32 rise and fall within the mating groove 33, the docking limiting plate 46 and docking block 47 move synchronously, allowing sliding blocks 41, guide rods 36, and stacking blocks 32 to rise and fall synchronously. The docking block 47 ensures that sliding blocks 41 slide stably and do not tilt. Positioning plate 55 connects two stacking blocks 32 for synchronous rising and falling. When adjusting the height of the stacking block 32, the linear driver 52 is activated, which drives the threaded rod 53 to rotate, causing the connecting limiting block 54 and the stacking block 32 to rise and fall synchronously, adapting to materials of different heights.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
