Description
Technical Field
[0001] This utility model relates to the field of feeding mechanisms, and in particular to a quantitative feeding, weighing, and calibration mechanism for plastic granules. Background Technology
[0002] In the modern plastics manufacturing industry, plastic granules are the core raw material, and the accuracy of their quantitative feeding plays a decisive role in product quality and production stability. With the popularization of automated production lines, the requirements for the metering accuracy and feeding efficiency of plastic granules are constantly increasing.
[0003] Traditional quantitative feeding and weighing systems for plastic granules have several shortcomings: Firstly, during prolonged use, the weighing sensors are susceptible to interference from environmental factors such as temperature and humidity, and mechanical vibration, leading to a gradual accumulation of measurement errors and making it difficult to guarantee continuous accuracy. Secondly, existing mechanisms lack real-time calibration capabilities, failing to dynamically correct measurement deviations caused by changes in material characteristics (such as fluctuations in particle density and differences in moisture content), resulting in inconsistent product quality across batches and impacting production efficiency and economic benefits. Furthermore, the calibration process for traditional mechanisms is complex, requires manual intervention, is time-consuming and labor-intensive, and is susceptible to human error.
[0004] The inability to automatically feed materials not only leads to a significant reduction in production efficiency, requiring frequent pipe clearing and material adjustment, increasing labor costs, but also causes product quality fluctuations due to unstable material feeding, resulting in raw material waste and equipment wear. There is an urgent need to improve existing technologies and overcome the technical bottleneck of the inability of plastic granule quantitative feeding and weighing calibration mechanisms to automatically feed materials in order to meet the needs of high-quality development in the industry. To this end, a plastic granule quantitative feeding and weighing calibration mechanism is proposed to solve the above problems. Utility Model Content

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.
[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a plastic granule quantitative feeding and weighing calibration mechanism, including a supporting shell 1, which serves as the basic frame of the entire mechanism, providing mounting support for the rotating rod opening and closing mechanism 2 and the stirring and discharging mechanism 3, and protecting the internal components from external environmental interference. The rotating rod opening and closing mechanism 2 is fixedly connected to the outside of the supporting shell 1, and the stirring and discharging mechanism 3 is rotatably connected to the inside of the supporting shell 1. The rotating rod opening and closing mechanism 2 includes a driving assembly 21 for driving, and a fixed connecting block 22 is fixedly connected to the top of the driving assembly 21 as a fixed fulcrum for the driving assembly 21 to improve system stability. A rotating gear 23 is fixedly connected to the outside of the driving assembly 21. A sliding rack 24 is slidably connected to the outside of the supporting shell 1, and a sliding support plate 25 is fixedly connected to the outside of the sliding rack 24. The external teeth of the sliding rack 24 and the external teeth of the rotating gear 23 are meshed with each other. A second sliding rack 27 is slidably connected to the outside of the supporting shell 1, and a second sliding support plate 26 is fixedly connected to the outside of the sliding rack 27. The external teeth of the second sliding rack 27... The outer teeth of the toothed and sliding rack 24 are meshed with each other. The outer part of the rotating gear 23 is rotatably connected to the outside of the supporting housing 1. The outer part of the sliding support plate 25 is slidably connected to the outside of the supporting housing 1. The outer part of the sliding support plate 26 is slidably connected to the outside of the supporting housing 1, forming the opening and closing gate of the feeding port. The feeding amount is controlled by the opposite or opposite movement. The outer part of the fixed connecting block 22 is fixedly connected to the outside of the supporting housing 1. The drive assembly 21 includes a rotating motor 211, which provides the power source and realizes forward and reverse rotation control. The opening and closing action of the feed port is achieved by a rotating connecting column 212 fixedly connected to the drive end of the rotating motor 211, which transmits the output torque of the motor to the rotating gear 23. At the same time, the rotating motor 211 is fixedly connected to the outside of the fixed connecting block 22, and the rotating connecting column 212 is rotatably connected to the outside of the support shell 1. The rotating gear 23 is fixedly connected to the outside of the rotating connecting column 212, which converts the rotational motion into linear motion and drives the sliding support plate 25 and the sliding support plate 26 to open and close synchronously.
[0033] Reference Figures 1 to 3The mixing and feeding mechanism 3 includes a second rotating motor 31 that drives the mixing assembly to rotate, ensuring smooth feeding. The driving end of the second rotating motor 31 is fixedly connected to a connecting rotating column 32, which serves as the main rotating shaft of the mixing assembly and transmits the motor torque to each mixing blade. A second connecting fixing column 35 is fixedly connected to the outside of the connecting rotating column 32. A rotating mixing blade 36 is fixedly connected to the outside of the connecting fixing column 35. A third connecting fixing column 37 is fixedly connected to the outside of the rotating mixing blade 36, i.e., the end away from the second connecting fixing column 35. A first connecting fixing column 33 is fixedly connected to the outside of the connecting rotating column 32. A connecting mixing blade 34 is fixedly connected to both ends of the first connecting fixing column 33 to mix the bottom area of the feeding storage bin 38 and break up particle agglomeration. The feeding storage bin 38 is rotatably connected to the outside of the connecting mixing blade 34 to store the plastic particles to be fed and provide a buffer space. The outside of the first connecting fixing column 33 and the second connecting fixing column 35 is rotatably connected to the inside of the feeding storage bin 38.
[0034] Working principle: When material needs to be unloaded, the operation of the gravity sensor transmits electricity to the rotating motor 211, which drives the rotating connecting column 212 to rotate. This drives the rotating gear 23 to rotate, and at the same time drives the sliding rack 24 and the sliding support plate 25 to move inward. Meanwhile, the rotating gear 23 drives the sliding rack 27 and the sliding support plate 26 to move inward, thereby achieving the opening and closing mechanism. At the same time, the fixed connecting block 22 provides support for the operation of the drive component 21, thus achieving the effect of automatic opening and closing.
[0035] When the system triggers the feeding command, the rotating motor 31 starts, driving the connecting rotating column 32 to rotate. The connecting rotating column 32 acts as the main shaft, synchronously driving the radially distributed connecting fixed column 33 and connecting fixed column 35 to rotate. The connecting stirring paddles 34 at both ends of the connecting fixed column 33 perform spiral stirring in the feeding storage bin 38 area, breaking up particle agglomerates and promoting downward flow. The rotating stirring paddle 36 on the outside of the connecting fixed column 35 rotates, enhancing the shearing and dispersing effect on the particles, avoiding large particles from getting stuck, and ensuring that the particles in the storage bin are in a uniform flow state, ensuring a smooth feeding process. The inverted conical design of the feeding storage bin 38 further reduces material residue and achieves efficient and residue-free feeding.
