All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] The first embodiment of this utility model: like Figures 1-4As shown in this embodiment, a conveyor belt type quantitative automatic unloading and weighing device for diaphragm particle processing mainly includes a frame 1, a hopper 2, a screw conveyor 3, a servo motor 4, a weighing bag assembly 7, a conveyor belt 6, and a guardrail 8. The hopper 2 is fixedly installed on the top of the frame 1 by a bracket 11. A feed inlet 9 is provided on one side of the top of the hopper 2 for feeding diaphragm particles, and a discharge outlet 12 is provided on one side of the bottom of the hopper 2. This discharge outlet 12 is sealed to the feed inlet on the top of the first side of the screw conveyor 3 to ensure smooth material transport. A transparent viewing window 10 is also provided on the hopper 2 to facilitate real-time observation of the liquid level in the hopper and prevent blockage or emptying. The screw conveyor 3 is horizontally installed on the frame 1, and a discharge outlet 5 is provided on its second side bottom for discharging materials. The servo motor 4 is fixed on one side of the frame 1 of the screw conveyor 3 and drives the screw conveyor 3 through a coupling or transmission mechanism to achieve controllable material transport.

[0028] A weighing bag assembly 7 is installed below the discharge port 5 of the screw conveyor 3. This assembly includes a weighing outer frame 13, a weighing base 14, a bag 15, a weighing device 16, and a bag clamping assembly 17. The weighing outer frame 13 is a rigid structure, fixed to the frame 1, providing stable support. The weighing base 14 is located at the bottom of the weighing outer frame 13, on which the bag 15 is placed to receive the material. The weighing device 16 is integrated inside or below the weighing base 14, using a high-precision sensor to detect the weight of the material in the bag 15 in real time, and transmits the data to the controller for processing. The bag clamping assembly 17 is installed on the top of the weighing outer frame 13 and includes multiple support rods and a clamping structure. The support rods are connected to the weighing outer frame 13 via a slide rail or threaded adjustment mechanism, so that the distance between them and the inner bag 15 is adjustable to accommodate bags of different sizes. The clamping structure is a buckle or a claw, used to clamp the top opening of the bag 15 to prevent the bag from shaking or falling off during the weighing process and to ensure weighing accuracy.

[0029] A conveyor belt 6 is installed on one side of the bottom of the frame 1. This conveyor belt 6 can be a powered or unpowered conveyor belt mechanism, used to transport the weighed bag assembly 7 to the next process. A guardrail 8 is installed along the outer side of the conveyor belt 6, with adjustable height, serving as a guide and protector to prevent the bags from shifting or falling during transport. In addition, the device includes a control system. The controller receives the weight signal from the weighing device 16, compares the set value with the actual value, and adjusts the speed of the servo motor 4 to achieve closed-loop control, ensuring quantitative unloading accuracy. The entire device has a compact structure, is suitable for continuous processing of diaphragm granules, and its automated design improves efficiency and reliability.

[0030] The working process of this embodiment is as follows: The diaphragm particles enter the hopper 2 through the inlet 9 and fall into the screw conveyor 3 through the outlet 12. The servo motor 4 drives the screw conveyor 3 to transport the material to the discharge port 5, where it falls into the material bag 15. The weighing device 16 monitors the weight of the material in real time. When the set value is reached, the controller controls the servo motor 4 to stop running. Then, the material bag clamping assembly 17 is released, and the material bag 15 filled with material is moved onto the conveyor belt 6. Guided by the guardrail 8, it is transported to the next station, completing the entire process of automatic quantitative unloading and conveying.

[0031] The second embodiment of this utility model: like Figures 1-4 As shown in this embodiment, a conveyor belt type quantitative automatic unloading and weighing device for diaphragm particle processing mainly includes: Frame 1: It adopts a steel structure frame to provide stable support, and the surface is treated with rust prevention to adapt to the industrial environment.

[0032] The hopper 2 is fixed to the top of the frame 1 by a bracket 11. It is made of stainless steel and has a smooth interior to reduce material adhesion. The inlet 9 is located on the top side and is used to receive diaphragm particles. The outlet 12 is located on the bottom side and is sealed to the inlet of the screw conveyor 3 to prevent leakage. The viewing window 10 is made of high-strength transparent glass or plastic and is embedded in the side of the hopper for easy real-time observation of the material level.

[0033] Screw conveyor 3: horizontally installed on frame 1, with the inlet and outlet 12 connected, and the discharge port (5) located at the bottom of its second side. The screw blades are made of wear-resistant material to ensure uniform conveying of diaphragm particles; the internal channel is designed to be gradually narrowing to promote material flow.

[0034] Servo motor 4: Mounted on the frame 1 on one side of the screw conveyor 3, it drives the shaft of the screw conveyor 3 via a coupling. The servo motor 4 has high torque and speed regulation functions, responding to controller signals to adjust the conveying speed.

[0035] Weighing bag assembly 7: Weighing outer frame 13: It is a rectangular frame structure that provides rigid support.

[0036] Weighing base 14: Installed at the bottom of the weighing outer frame 13, it supports the weight of the material bag 15 and the material.

[0037] Weighing device 16: Integrated in the weighing base 14, it uses a high-precision sensor (such as a strain gauge) to detect the weight of the material in the bag 15 in real time and transmit the data to the controller (not shown).

[0038] Material bag 15: Placed on weighing base 14, used to receive diaphragm particles.

[0039] The bag clamping assembly 17 includes a support rod and a clamping structure. The support rod is mounted on top of the weighing outer frame 13 by screws or slide rails, and its horizontal position is adjustable (by a sliding mechanism or thread) to accommodate bags 15 of different diameters. The clamping structure is a snap-fit ​​or jaw, such as a spring jaw or a magnetic snap-fit, used to clamp the top opening of the bag 15 to prevent it from shaking or falling off during weighing.

[0040] Conveyor belt 6: Located on one side of the bottom of frame 1, it can be a powered conveyor belt (driven by a motor) or a non-powered conveyor belt (relying on manual pushing), with an anti-slip layer on the surface. Guardrail 8 is installed along the outside of conveyor belt 6, with adjustable height, and is used to guide the transport of material bags and prevent deviation.

[0041] Control system (not shown): includes a controller (such as a PLC or microprocessor) that can be connected to the weighing device 16 and the servo motor 4. The controller presets a weight value and adjusts the speed of the servo motor 4 by comparing the actual weight with the set value to achieve quantitative control.

[0042] A brief description of the working process in this embodiment: Initial preparation: The operator adds the diaphragm particles to the hopper 2 through the feed inlet 9 and observes the liquid level through the viewing window 10 to ensure sufficient material. Adjust the position of the support rod of the bag clamping assembly 17 so that the clamping structure (using claws) is aligned with the opening of the bag 15 and clamped in place.

[0043] Start the conveyor: The controller starts the servo motor 4, which drives the screw conveyor 3 to run. The diaphragm particles enter the screw conveyor 3 from the hopper 2 through the discharge port 12 and move along the screw blades towards the discharge port 5.

[0044] Dynamic weighing: Material falls from discharge port 5 into material bag 15. Weighing equipment 16 monitors the weight data in real time and sends it to the controller. The controller calculates the instantaneous flow rate and compares it with the set value (5kg). It then adjusts the speed of servo motor 4 using a PID algorithm to ensure stable conveying. For example, when the actual weight is close to the set value, the controller reduces the speed to achieve precise feeding.

[0045] Quantitative Stop: When the weighing device 16 detects a weight of 5kg, the controller sends a signal to stop the servo motor 4, and the screw conveyor 3 pauses feeding. The bag clamping assembly 17 remains clamped to ensure that the bag 15 does not shake during weighing.

[0046] Unloading and transport: The operator releases the grippers of the bag clamping assembly 17 and pushes the full bag 15 onto the conveyor belt 6. The conveyor belt 6 starts automatically and, guided by the guardrail 8, transports the bag 15 to the next process (such as packaging or storage).

[0047] Cyclic operation: Repeat the above process to achieve continuous quantitative dispensing. Throughout the process, the viewing window 10 facilitates monitoring of the silo status, and the design of the screw conveyor 3 reduces material residue and ensures metering accuracy.
