Description

Technical Field

[0001] This utility model relates to the field of powder batching system technology, and more specifically, to a batching hopper with shock-absorbing components. Background Technology

[0002] The existing batching hopper consists of: a hopper cover, a hopper, a weighing sensor, a vibrating motor, a pneumatic butterfly valve, and a discharge port. Generally, the hopper cover has two or more feed ports, each corresponding to a different material. Material is automatically fed using either a screw feeder or a vacuum feeder. When a material begins to be fed, the weighing sensor activates. When the weighing sensor detects that the material has reached the predetermined weight, it sends a signal to the control center. The control center then shuts off the screw feeder or vacuum feeder, stopping the feeding. This process is repeated for each feed port. Before batching, the specific gravity of each material is pre-input into the program. At this point, the material mixing stage is complete. Next, the pneumatic butterfly valve at the discharge port opens, discharging the mixed material into the reactor.

[0003] Due to differences in industry and production formulas, the type, proportion, and weight of materials entering the batching hopper vary significantly. If too much powder or material with high viscosity enters the batching hopper, it can easily lead to the following situations:

[0004] 1. Highly viscous materials can cause bridging in the feeding hopper, preventing them from entering the extruder below and causing the production line to stop.

[0005] 2. The powder adheres to the wall inside the feeding hopper, causing uneven material entry into the extruder below. This leads to increased load fluctuations and unstable current in the extruder motor, and in severe cases, motor overload and tripping.

[0006] 3. Under high-volume conditions, the materials entering the batching process often mix with air, resulting in a decrease in the overall bulk density of the materials. This reduces the feed rate of the extruder and affects the output of the entire production line. Utility Model Content

[0007] The purpose of this invention is to provide a batching hopper with a shock-absorbing component. The hopper is divided into an upper hopper and a lower hopper, which are then connected by bolts, shock-absorbing springs, and a flexible polyester straight-through cloth bag. The lower hopper is suspended in the air by bolts, ensuring that the weight of the upper hopper and the material is evenly distributed on the weighing sensor. This guarantees that the lower hopper vibrates as a whole under the action of the vibration motor, thus solving the problems of material bridging and sticking to the walls inside the lower hopper. Through vibration, the lower hopper compacts the material inside, expels internal air, increases material density, and thus increases output.

[0008] The technical solution adopted by this utility model is: a batching hopper with shock absorption components, including a batching hopper support and a batching hopper, characterized in that: the batching hopper includes an upper hopper part and a lower hopper part, three sets of pads are fixed at equal intervals on the outer wall of the upper part of the upper hopper part, and a weighing sensor is connected to the bottom end of each of the three sets of pads, and the three sets of weighing sensors are fixed to the top of the batching hopper support.

[0009] An upper bucket flange is fixed to the outer wall of the middle part of the upper bucket section, and a straight cylindrical section of the upper bucket section is fixedly connected below the upper bucket flange.

[0010] The upper part of the lower bucket is a straight section, and the lower part is a conical section. A lower bucket flange is fixed to the outer wall of the bottom of the straight section. There is a gap between the upper bucket and the lower bucket. Flexible connecting polyester straight-through cloth bags are provided around the outer sides of the upper and lower bucket straight sections. The outer surface of the flexible connecting polyester straight-through cloth bag surrounding the outer wall of the upper bucket is provided with an upper bucket straight-through section clamp. The outer surface of the flexible connecting polyester straight-through cloth bag surrounding the outer wall of the lower bucket is provided with a lower bucket straight-through section clamp.

[0011] The lower bucket flange is connected to the upper bucket flange by several evenly distributed shock-absorbing springs and bolts. The bottom end of the lower bucket flange is fixedly connected to an upper spring seat. The bottom of the bolt is fitted with a lower spring seat. The shock-absorbing spring is fitted on the lower spring seat. The bolt passes through the hole in the upper spring seat and the hole in the upper bucket flange. The top end of the bolt is fixedly connected to the upper bucket flange by a fixing nut and a locking nut in sequence.

[0012] Several vibrating motors are fixed to the outer wall of the conical section of the lower bucket. The vibrating motors are arranged at different heights. A pneumatic butterfly valve is installed at the bottom of the conical section of the lower bucket, and the outlet of the pneumatic butterfly valve is connected to the discharge port.

[0013] Furthermore, the top of the upper bucket is provided with several bucket covers.

[0014] The beneficial effects of this utility model are:

[0015] 1. The batching hopper is divided into an upper hopper and a lower hopper. The two hoppers are then connected using bolts, shock-absorbing springs, and flexible polyester straight-through cloth bags. The lower hopper is lowered into the air by bolts, ensuring that the weight of the upper hopper and the material is evenly distributed on the weighing sensor. This guarantees that the lower hopper vibrates as a whole under the action of the vibrating motor, thus solving the problems of material bridging and sticking to the walls inside the lower hopper. The vibration of the lower hopper compacts the material inside, expels internal air, increases material density, and thus increases output.

[0016] 2. By separating the weighing sensor and the vibrating motor into two parts, the vibrating motor can be used to vibrate the outer wall of the hopper to smoothly shake off the materials adhering to the wall, improving the accuracy of each batching in the material mixing process. By isolating the vibration force of the vibrating motor in the transmission path, the weighing sensor is not subjected to the vibration force of the vibrating motor, which does not affect the weighing accuracy. This ensures the smooth discharge of each batch of mixed materials and also prevents the weighing sensor from being damaged by vibration, greatly reducing the company's operating costs.

[0017] 3. The upper and lower buckets of the batching hopper are damped by shock-absorbing springs, which reduces the impact of the batching hopper on the weighing sensor and platform above during operation. Attached Figure Description

[0028] like Figures 1-6 As shown: This utility model is a batching hopper with shock absorption components, including a batching hopper support 21 and a batching hopper 1. The batching hopper 1 includes an upper hopper part 2 and a lower hopper part 3. Three sets of pads 22 are fixed at equal intervals on the outer wall of the upper part of the upper hopper part 2. The bottom end of each of the three sets of pads 22 is connected to a weighing sensor 23. The three sets of weighing sensors 23 are fixed to the top of the batching hopper support 21.

[0029] The outer wall of the middle part of the upper bucket 2 is fixed with an upper bucket flange 16, and the lower part of the upper bucket flange 16 is fixedly connected with an upper bucket straight section 17.

[0030] The upper part of the lower bucket section 3 is a straight section 19, and the lower part of the lower bucket section 3 is a conical section. The outer wall of the bottom of the straight section 19 is fixed with a lower bucket flange 18. There is a gap between the upper bucket section 17 and the lower bucket section 19. The outer sides of the upper bucket section 17 and the lower bucket section 19 are surrounded by a flexible connecting polyester straight-through cloth bag 4. The outer surface of the flexible connecting polyester straight-through cloth bag 4 surrounding the outer wall of the upper bucket section 17 is provided with an upper bucket section straight-through clamp 5. The outer surface of the flexible connecting polyester straight-through cloth bag 4 surrounding the outer wall of the lower bucket section 19 is provided with a lower bucket section straight-through clamp 6.

[0031] The lower bucket flange 18 is connected to the upper bucket flange 16 by a number of evenly distributed shock-absorbing springs 7 and bolts 8. The bottom end of the lower bucket flange 18 is fixedly connected to the upper spring seat 9. The bottom of the bolt 8 is fitted with the lower spring seat 10. The shock-absorbing spring 7 is fitted on the lower spring seat 10. The bolt 8 passes through the hole of the upper spring seat 9 and the hole of the upper bucket flange 16. The top end of the bolt 8 is fixedly connected to the upper bucket flange 16 by a fixing nut 11 and a locking nut 12 in sequence.

[0032] Several vibrating motors 13 are fixed on the outer wall of the conical section of the lower bucket 3. The vibrating motors 13 are arranged at different heights. A pneumatic butterfly valve 14 is installed at the bottom of the conical section of the lower bucket 3. The outlet of the pneumatic butterfly valve 14 is connected to the discharge port 15.

[0033] The top of the upper bucket 2 is provided with several bucket covers 20.

[0034] The working process of this practical model:

[0035] When the equipment is working, various materials enter the feeding hopper 1 through the upper cover 20. Under the vibration of the vibrating motor 13, the materials can fall smoothly into the feed port of the main machine and then enter the extruder.

[0036] The feeding hopper 1 is divided into two parts: an upper hopper 2 and a lower hopper 3. The two parts are then connected by bolts 8, shock-absorbing springs 7, and a flexible polyester straight-through cloth bag 4. The lower hopper 3 of the feeding hopper 1 is lowered into the air by bolts 8, so that the weight of the upper hopper 2 and the material in the feeding hopper 1 is evenly distributed on the weighing sensor 23. This ensures that the lower hopper 3 vibrates as a whole under the action of the vibration motor 13, thereby solving the problems of material bridging and hanging on the wall inside the lower hopper 3. Through vibration, the lower hopper 3 compacts the material inside, expels the internal air, increases the material density, and thus increases the output.

[0037] By separating the weighing sensor 23 from the vibration motor 13, the vibrating motor 13 can be used to vibrate the material adhering to the wall of the lower hopper 3 to be smoothly shaken down, improving the accuracy of each batching in the material mixing process. By isolating the vibration force of the vibration motor 13 in the transmission path, the weighing sensor 23 is not subjected to the vibration force of the vibration motor 13, which does not affect the weighing accuracy, ensures the smooth discharge of each batch of mixed materials, and also ensures that the weighing sensor 23 is not damaged by vibration, greatly reducing the company's operating costs.

[0038] The upper bucket 2 and lower bucket 3 of the batching hopper 1 are damped by shock-absorbing springs 7, which reduces the impact of the batching hopper 1 on the weighing sensor 23 above and the platform when it is working.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
