[0030] Example
[0031] like Figure 1 and Figure 2As shown, this utility model proposes an automatic feeding and metering mechanism for plastic granules, comprising: a storage bin 1 for storing plastic granules, the storage bin 1 being made of a high-strength and corrosion-resistant material, effectively resisting the erosion that may occur from long-term storage of plastic granules; a partition 2 fixedly installed inside the storage bin 1, the partition 2 being ingeniously designed to precisely divide the interior of the storage bin 1 into two storage chambers, facilitating the classification and storage of plastic granules of different specifications or colors, greatly improving the flexibility and convenience of production; a feeding hopper 3 and a first discharge pipe 4 respectively connected to the upper and lower ends of the storage bin 1; the feeding hopper 3 having a large opening, facilitating the use of large feeding equipment or manual direct pouring of plastic granules by operators, and corresponding to the two storage chambers, ensuring that the material accurately enters the corresponding compartment; and a metering component 5 installed at the bottom of the storage bin 1 for metering plastic granules, and the metering component 5 being movable. The first discharge pipe 4 is fitted with a solenoid valve to control the discharge of plastic granules. This design makes the metering process more accurate and convenient, and can monitor the discharge of plastic granules in real time, providing reliable data support for subsequent production processes. The fixed collar 6 is fitted with a fixed collar on the outer wall of the storage tank 1. The fixed collar 6 plays a role in stabilizing the overall structure of the storage tank 1. Multiple support legs 7 are fixedly installed on its bottom surface to support the storage tank 1, providing good support stability and preventing shaking or tipping during equipment operation. The presence of the mixing component 8 allows plastic granules from different batches or those that have slightly separated during storage to be fully mixed evenly, ensuring the consistency of the quality of subsequent processed products. The outer wall of the mixing component 8 is fixedly equipped with a support rod 9, one end of which is fixedly connected to the support leg 7, further enhancing the installation stability of the mixing component 8.
[0032] like Figures 3 to 5 As shown, the metering component 5 includes a metering storage tank 51 movably sleeved on the outer wall of the first discharge pipe 4. The inner wall of the metering storage tank 51 is specially smoothed to effectively reduce the residue of plastic particles during the discharge process. A spring 52 is sleeved on the outer wall of the first discharge pipe 4. One end of the spring 52 is fixedly connected to the metering storage tank 51, and the other end of the spring 52 is fixedly connected to a pressure ring 53. The pressure ring 53 is movably sleeved on the first discharge pipe 4. An annular pressure sensor 54 is provided on the bottom surface of the pressure ring 53. The annular pressure sensor 54 uses a high-precision sensing element, which can sensitively capture the pressure difference caused by the change in material weight, thereby accurately measuring the discharge amount. The annular pressure sensor 54 is connected to the solenoid valve on the first discharge pipe 4 through the control system. The control system is existing technology and will not be described in detail here. It is fixedly sleeved on the first discharge pipe 4 to facilitate the control of the opening and closing of the first discharge pipe 4. A discharge port 55 is opened on one side of the metering storage tank 51 to facilitate the discharge of plastic particles in the metering storage tank 51.
[0033] Further, the metering component 5 further includes a set of guide rails 56 fixedly arranged at the discharge port 55. The surface of the guide rails 56 is smooth and wear-resistant, ensuring that the baffle 57 slides smoothly thereon. A baffle 57 is slidably arranged on the guide rails 56. The baffle 57 has good sealing performance to prevent material leakage. A second discharge pipe 58 is connected thereto. The diameter of the second discharge pipe 58 is reasonably designed according to the actual discharge requirement. An electric push rod 59 is arranged at the upper end of the baffle 57. The electric push rod 59 is fixedly installed on the outer wall of the storage barrel 1. The electric push rod 59 is connected to the annular sensor through the control system, and can accurately control the switch of the electric push rod 59, and can flexibly open or close the discharge port 55 to achieve the purpose of quantitative discharge.
[0034] As Figure 1 and Figure 2 shown, the mixing component 8 includes a material receiving barrel 81. A motor 82 is fixedly installed at the bottom of the material receiving barrel 81. The output end of the motor 82 penetrates through the material receiving barrel 81 and extends to the inside to be connected with a stirring blade 83 for stirring plastic particles, facilitating the uniform stirring of the plastic particles inside the material receiving barrel 81. A third discharge pipe 84 is connected to the bottom surface of the material receiving barrel 81, and a solenoid valve is arranged on the third discharge pipe 84, facilitating the control of the discharge of plastic particles and facilitating the discharge of the plastic particles inside the material receiving barrel 81.
[0035] Secondly, a set of guide plates 10 are fixedly arranged on the bottom surface of the storage barrel 1. Guide grooves 11 are formed on the outer wall of the metering storage barrel 51. The guide grooves 11 are slidably connected with the guide plates 10, which can stably guide the metering storage barrel 51 and make the metering storage barrel 51 move vertically and stably up and down.
[0036] Furthermore, the inner bottom surface of the metering storage barrel 51 is inclined, facilitating the discharge of the plastic particles inside the metering storage barrel 51.
[0037] In addition, the guide plates 10 and the guide grooves 11 are arranged in a "convex" shape structure, which can make the metering storage barrel 51 move stably under guidance. [[ID= 17]]
[0038] The working principle of this embodiment is as follows: First, different types of plastic particles are poured into the storage barrel 1 through the feeding hopper 3, and the added plastic particles are separated into two storage chambers by the partition plate 2. At the bottom of the storage barrel 1, when discharging, the plastic particles enter the metering storage barrel 51 through the first discharge pipe 4. The metering storage barrel 51 starts to move downward under the gravity of the plastic particles. At this time, the spring 52 sleeved on the outer wall of the first discharge pipe 4 is pressed down, and the pressure ring 53 moves down accordingly. The annular pressure sensor 54 on the bottom surface of the pressure ring 53 can sense the pressure change in real time, thereby measuring the weight of the plastic particles flowing out of the first discharge pipe 4 and falling into the metering storage barrel 51. When the preset weight is reached, the control system receives the signal to pause the discharge of the first discharge pipe 4.
[0039] Subsequently, the control system activates the electric push rod 59 to drive the baffle 57 to slide vertically downward on a set of guide rails 56. The baffle 57 drives the second discharge pipe 58 to move vertically downward, so that the second discharge pipe is connected to the discharge port 55, thereby discharging the particles in the metering storage tank 51 into the receiving tank 81.
[0040] Afterwards, the motor 82 drives the stirring blade 83 to stir the plastic granules falling into the receiving bucket 81, preventing the granules from clumping and ensuring smooth feeding. The stirred granules flow out through the third discharge pipe 84. Precise control of the discharge timing and quantity avoids material waste or processing problems caused by inaccurate estimation during manual feeding, greatly improving production accuracy, significantly shortening feeding time, meeting the rhythm of large-scale, high-efficiency industrial production, effectively solving the problem of production delays, and improving overall production efficiency.
[0041] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
