Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, and in particular to flow dividers. Background Technology

[0002] In the plastic recycling and injection molding process, crushers are typically used to break down waste plastics into granular materials, which are then transported to injection molding machines for further processing. In traditional processes, crushers and injection molding machines are usually connected in a one-to-one direct feeding method, meaning the crusher directly feeds material into the hopper of one injection molding machine through a single pipe. However, the production efficiency of injection molding machines is limited by factors such as molding cycles and mold changes, and their material consumption rate is often lower than the crusher's feeding capacity, resulting in a natural mismatch in their production rhythms.

[0003] The existing one-to-one feeding mode between crushers and injection molding machines has significant drawbacks. Because the feeding speed of the crusher is generally higher than the actual production speed of the injection molding machine, excess plastic particles easily accumulate in the injection molding machine hopper, even causing overflow and blockages, affecting production continuity. In some scenarios, intermediate storage silos are added to buffer feeding discrepancies, but these silos occupy a large space and increase management costs, failing to fundamentally optimize feeding efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a flow divider, which can effectively solve the technical problem that the feeding speed of the crusher and the production efficiency of the injection molding machine are mismatched when the existing crusher and injection molding machine are connected in a one-to-one manner.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The diverter includes a diverter housing with a separation chamber inside. The surface of the diverter housing has three interfaces: a feed inlet, a first diverter port, and a second diverter port. These three ports are interconnected through the separation chamber. A rotatable diverter plate is housed within the separation chamber. One end of the diverter plate has a rotating shaft located at the end of the separation chamber furthest from the feed inlet, between the first and second diverter ports. The diverter plate rotates relative to the diverter housing within the separation chamber around the rotating shaft. One end of the rotating shaft passes through the diverter housing and has an adjusting component. The surface of the adjusting component has a limiting groove that follows the same rotation trajectory as the diverter plate. The surface of the diverter housing has a tightening nut and a limiting stud. The limiting stud passes through the limiting groove, and the tightening nut is screwed onto the limiting stud. When the tightening nut and limiting stud are tightened, the tightening nut presses the adjusting component against the surface of the diverter housing.

[0007] Furthermore, the surface of the diversion housing is provided with two opposing positioning holes, and the two ends of the rotating shaft are respectively inserted into the two positioning holes. The end of the rotating shaft near the adjusting component is provided with a connecting hole, and the adjusting component is fixedly connected to the rotating shaft by bolts.

[0008] Furthermore, the edge of the adjusting member is provided with a control wrench for moving the diverter plate, and the edge of the limiting slot is provided with an indicator scale.

[0009] Furthermore, the feed inlet, the first diversion port, and the second diversion port are all equipped with connecting pipe heads.

[0010] Furthermore, a transition section is provided between the feed inlet, the first diversion port, the second diversion port and the connecting pipe head, and the cross-sections of the two ends of the transition section are consistent with the cross-sections of the connecting pipe head and the interface, respectively.

[0011] Furthermore, the side wall of the diversion housing is provided with an observation window, and a transparent PC board is provided on the outside of the observation window. The transparent PC board is installed with the diversion housing through a fixing frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the first and second diversion ports of the diverter can be connected to two injection molding machines respectively. By adjusting the flip angle of the diverter plate, materials can be flexibly distributed to different injection molding machines. The diverter plate can be flipped and adjusted in the separation chamber via a rotating shaft, and its angle is controlled by an adjusting component. By rotating the adjusting component, the diverter plate can precisely adjust the ratio of material flow to the first and second diversion ports, thereby dynamically allocating the material supply according to the actual production needs of the injection molding machines. This ensures that the feeding speed of the crusher matches the production speed of multiple injection molding machines, avoiding material accumulation or blockage due to excessive material supply to a single injection molding machine, while improving the utilization rate of the crusher. After the diverter plate is adjusted to the target angle, tightening the loosening nut locks the position of the adjusting component, ensuring that the diverter plate remains stable during high-speed material flow and preventing the diversion ratio from shifting due to vibration or pressure changes, thus ensuring the uniformity of diversion and the continuity of material supply.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The following is combined Figures 1-4 The shunt of this utility model is described in detail as follows:

[0020] The diverter includes a diverting housing 1, within which a separation chamber 2 is disposed. The surface of the diverting housing 1 has three interfaces: an inlet 3, a first diverting port 4, and a second diverting port 5. The inlet 3, first diverting port 4, and second diverting port 5 are interconnected through the separation chamber 2. A rotatable diverting plate 6 is disposed within the separation chamber 2. One end of the diverting plate 6 has a rotating shaft 7 located at the end of the separation chamber 2 furthest from the inlet interface and between the first diverting port 4 and the second diverting port 5. The diverting plate 6 rotates relative to the diverting housing 1 within the separation chamber 2 about the rotating shaft 7. The surface of the diverting housing 1 has two opposing positioning holes 8, into which two positioning holes are inserted at the ends of the rotating shaft 7. In the positioning hole 8, one end of the rotating shaft 7 passes through the diversion housing 1 and is provided with an adjusting component 10. A connecting hole 9 is provided at the end of the rotating shaft 7 near the adjusting component 10. The adjusting component 10 is fixedly connected to the rotating shaft 7 by bolts. The surface of the adjusting component 10 is provided with a limiting groove 11 that matches the flipping trajectory of the diversion plate 6. The surface of the diversion housing 1 is provided with a tightening nut 13 and a limiting stud 12. The limiting stud 12 passes through the limiting groove 11, and the tightening nut 13 is screwed onto the limiting stud 12. When the tightening nut 13 and the limiting stud 12 are tightened, the tightening nut 13 presses the adjusting component 10 against the surface of the diversion housing 1. Adjusting the diversion plate 6 only requires loosening the tightening nut 13, rotating the adjusting component 10, and then re-tightening it, without the need for complex tools or machine downtime. This simple adjustment method significantly reduces the technical threshold and time cost of maintaining the feeding system, making it suitable for fast-response production environments.

[0021] The first and second diversion ports 4 and 5 of the distributor can be connected to two injection molding machines respectively. By adjusting the flip angle of the distributor plate 6, materials can be flexibly distributed to different injection molding machines. The distributor plate 6 can be flipped and adjusted in the separation chamber 2 via the rotating shaft 7, and its angle is controlled by the adjusting component 10. By rotating the adjusting component 10, the diverter plate 6 can precisely adjust the ratio of material flow to the first diverter port 4 and the second diverter port 5, thereby dynamically allocating the material supply according to the actual production needs of the injection molding machine. This ensures that the feeding speed of the crusher matches the production speed of multiple injection molding machines, preventing material accumulation or blockage due to excessive material supply to a single injection molding machine, and improving the utilization rate of the crusher. After the diverter plate 6 is adjusted to the target angle, tightening the loosening nut 13 locks the position of the adjusting component 10, ensuring that the diverter plate 6 remains stable during high-speed material flow and preventing the diversion ratio from shifting due to vibration or pressure changes. This ensures uniform diversion and continuous material supply. The diverter is directly integrated into the feeding pipeline. The real-time adjustment of the diverter plate 6 balances the material supply differences, eliminating the need for an intermediate storage silo, saving equipment space and storage management costs, and reducing the risk of material contamination during storage and transportation.

[0022] The edge of the adjusting component 10 is equipped with a control wrench 14 for adjusting the flow divider 6, and the edge of the limiting slot 11 is equipped with an indicator scale 15. Operators can intuitively adjust the angle of the flow divider 6 by operating the control wrench 14, and precisely control the ratio of material flow to the first flow divider 4 and the second flow divider 5 by combining the scale indication. This design makes the flow ratio adjustment more intuitive and convenient, ensuring uniform material distribution and smooth flow, and avoiding local accumulation or flow interruption caused by adjustment errors.

[0023] The feed inlet 3, the first diversion port 4, and the second diversion port 5 are all equipped with connecting pipe heads 16. A transition section 17 is provided between the feed inlet 3, the first diversion port 4, the second diversion port 5 and the connecting pipe head 16. The cross-sections of the two ends of the transition section 17 are consistent with the cross-sections of the connecting pipe head 16 and the interface, respectively. The gradual cross-section design of the transition section 17 effectively reduces the sudden resistance when the material flows through the interface, avoids eddies or material accumulation caused by sudden changes in cross-section, further optimizes the fluid dynamics characteristics of the diversion channel, and ensures smooth and unobstructed material diversion.

[0024] The side wall of the diversion housing 1 is provided with an observation window 18. A transparent PC plate 20 is provided on the outside of the observation window 18. The transparent PC plate 20 is installed with the diversion housing 1 through the fixing frame 19. The operator can monitor the flow status of the material in the separation chamber 2 and the working position of the diversion plate 6 in real time through the observation window 18, promptly detect uneven diversion or blockage risks, and quickly correct them through the adjusting component 10 to ensure that the diversion process is always in a controllable and smooth state.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
