[0028] In the prior art, the metering and feeding device of the plasticizer is mostly operated manually, that is, the operator first calculates the required weight of the plasticizer according to the production needs, and then adds the plasticizer to the feeding device for standby use. Although this method is simple, the manual calculation operation is prone to errors; in actual production, the amount of plasticizer material calculated is often different from the actual amount required for production. During the production process, if it is found that the plasticizer is insufficient, it is necessary to stop the machine and add it again, resulting in production interruption and reducing production efficiency; due to the lack of automated metering and adjustment mechanisms, the excess plasticizer in the production process cannot be effectively recycled, further increasing production costs.
[0029] In view of this, the present invention provides a metering feeding device, referring to Figure 1, including a support platform 1, a support frame 2 is mounted on the support platform 1, and a hopper 3 is fixed on the support frame 2; the top of the hopper 3 is airtightly connected to a dust collecting bin 4, and the lowest point of the filter bag of the dust collecting bin 4 is located in the hopper 3; the top of the dust collecting bin 4 is airtightly connected to an exhaust pipe 401, and an exhaust pump is installed at the other end of the exhaust pipe 401; a collecting bin 303 with an opening at the top is mounted in the hopper 3, and a first gravity sensor is fixed at the bottom of the collecting bin 303. When the material enters the collecting bin 303, the first gravity sensor The sensor is used to detect the weight of the material in the collecting bin 303; a second gravity sensor 304 is installed on the outer wall of the hopper 3, and when the material enters the hopper 3, the second gravity sensor 304 is used to detect the weight of the material in the hopper 3; the discharge port at the bottom of the hopper 3 is located below the bottom of the support frame 2, and a discharge valve is installed at the discharge port of the hopper 3; a feed pipe 5 is airtightly connected to the outer wall of the hopper 3, and the discharge port of the feed pipe 5 is located below the filter bag of the dust collecting bin 4 and above the collecting bin 303.
[0030] In some embodiments, a vibration pump 301 is also installed on the outer wall of the hopper 3. The function of the vibration pump 301 is to work during the discharge, maintain continuous vibration, so that the material in the hopper 3 is vibrated and separated, and discharged smoothly through the discharge port.
[0031] In some embodiments, an air hole 302 is further provided on the outer wall of the hopper 3, and a one-way valve is installed on the air hole 302 to allow gas to enter the hopper 3 in one direction. The air hole 302 is provided, and the air hole 302 can be connected to a compressor, and the compressor is used to allow clean gas to enter the hopper 3 through the one-way valve. The material inside the hopper 3 cannot flow out of the hopper 3 under the control of the one-way valve. The clean gas flows in the hopper 3 to assist the vibration pump 301 to remove the material, and then it is smoothly discharged from the discharge port.
[0032] In some embodiments, there are three air holes 302, one of which is located on the outer wall of the hopper 3 below the vibration pump 301, and the other two air holes 302 are located above the discharge valve, and the central axes of the two air holes 302 located above the discharge valve are collinear. One air hole 302 is set on the outer wall of the hopper 3 at a height below the vibration pump 301, and the gas entering from the air hole 302 is used to blow the material inside the hopper 3 to make it fall off. Because the central axes of the two air holes 302 located above the discharge valve are collinear, when the compressor discharges the gas into the hopper 3, the gas forms a counter-attack, and the rebound force of the counter-attack circulates at the discharge port, blowing the material at the discharge port off.
[0033] In some embodiments, the volume of the collecting bin 303 does not exceed 10% of the maximum volume of the material contained in the hopper 3. The smaller the volume of the collecting bin 303, the easier it is to control the weight of the remaining material in the hopper 3.
[0034] In some embodiments, there is at least one feed pipe 5, and when the number of feed pipes 5 is greater than 1, the number of feed ports of the feed pipe 5 is equal to the number of feed pipes 5, and the number of discharge ports of the feed pipe 5 is 1. The more the number of feed pipes 5 is, the more uniform the feed is during feeding, and at this time, the diameter of the discharge port needs to be designed according to the power of the vacuum pump, and the diameter of the discharge port is positively correlated with the power of the vacuum pump.
[0035] In some embodiments, the outlet of the feed pipe 5 is connected with a hose, and the hose is used to absorb the material in all directions when the material enters the hopper 3 from the feed pipe 5. The material placed in the container is sucked in all directions and angles by the hose to prevent material waste or material weight not meeting the required standard weight.
[0036] In some embodiments, the discharge valve is a pneumatic butterfly valve 6 .
[0037] In some embodiments, the bottom of the support frame 2 is bolted to the top of the support platform 1 .
[0038] In some embodiments, a rubber layer is covered on the top of the support platform 1. The rubber layer is designed to cushion the support frame 2, reduce the friction between the support frame 2 and the support platform 1 when the vibration pump 301 is working, prevent the parts from loosening and being damaged, and increase the life of the equipment.
[0039] The working process of a metering feeding device provided by an embodiment of the utility model is as follows: placing the material at the feed port of the feed pipe 5, and burying the feed port in the material, turning on the vacuum pump connected to the exhaust pipe 401 at the top of the metering feeding device to exhaust air, and drawing negative pressure into the hopper 3. Since the hopper 3 is in a negative pressure state, the material will be sucked into the hopper 3 through the feed pipe 5. In some embodiments, a valve is also provided at the feed port of the feed pipe 5 to control the feed amount. During the material conveying process, the dust collecting bin 4 continues to operate, and the filter bag of the dust collecting bin 4 will remove dust from the gas drawn in by the exhaust pipe 401. The material first enters the collection bin 303 in the hopper 3, and the material exceeding the volume of the collection bin 303 is discharged and placed in the hopper 3. The weight of the material in the collection bin 303 is received by the first gravity sensor. The volume of the collecting bin 303 is selected according to actual needs to ensure that the volume of the collecting bin 303 does not exceed 10% of the volume of the material that the hopper 3 can accommodate, that is, 1.1 times the maximum volume of the material required in the hopper 3. The material that enters the hopper 3 and is not in the collecting bin 303 is detected by the second gravity sensor 304. If the volume of the collecting bin 303 is 10% of the volume of the material that the hopper 3 can accommodate, when the weight of the material required for production exceeds the theoretical demand for the material, the value detected by the second gravity sensor 304 needs to exceed 9 times the value detected by the first gravity sensor. When discharging, the vibration pump 301 is turned on to maintain continuous vibration to ensure that the material in the hopper 3 is discharged cleanly. In addition, the air hole 302 is connected to the compressor to inject clean gas into the hopper 3 to assist in the discharge of the material. The pneumatic butterfly valve 6 below the hopper 3 can control the speed of discharging when discharging, adapting to different production needs.
[0040] In summary, the utility model provides a metering feeding device, which designs a collection bin 303, uses the collection bin 303 to store materials, and uses the first gravity sensor to detect the weight of the materials in the collection bin 303. The gravity data can provide the second gravity sensor 304 with the help of material metering, thereby realizing automatic operation, reducing human errors, avoiding errors in manual calculation and operation, and improving the accuracy of the plasticizer when adding the material. The gravity sensor monitors the weight of the materials in the collection bin 303 in real time, and can timely detect the shortage of materials and automatically replenish them, avoiding production interruptions caused by insufficient materials. The replenishment mechanism ensures the continuous supply of plasticizers in the production process without stopping the machine for re-adding, which significantly improves production efficiency. The design adds a certain percentage of materials each time when adding materials, forming material redundancy, ensuring that there will be no shortage of materials even at peak demand. The material redundancy design improves the continuity and reliability of the production process, and reduces product quality problems caused by insufficient materials. Automatically metering and accurately controlling the amount of materials avoids the waste of materials caused by excessive addition, reduces production costs, reduces unnecessary waste, and realizes efficient use of resources. During the production process, when it is found that the material is insufficient, there is no need to stop the machine to add more materials. The materials stored in the collection bin 303 can be directly used for adding, which will not interrupt the production and improve the production efficiency. When there is excess plasticizer in the production process, the collection bin 303 can also recycle the materials. The materials stored in the collection bin 303 can be used for the next production, thereby reducing the production cost.
