Description

Technical Field

[0001] This utility model belongs to the field of gas cylinder detection technology and relates to an automatic weighing and detection device for gas cylinders. Background Technology

[0002] Gas cylinders are used in a wide range of fields, and the required specifications and weights of gas cylinders vary for different fields. Currently, gas cylinders need to be weighed and inspected manually one by one after production, which is inefficient and wastes manpower.

[0003] A Chinese utility model patent with publication number CN210881502U discloses an automatic weighing and marking system for steel cylinders. The system includes a conveyor support, a bracket for lifting the steel cylinder below the conveyor support, a lifting mechanism for moving the bracket up and down fixed at its lower end, a position sensor for sensing the conveying position of the steel cylinder fixed on one side of the bracket, a suction cup and a positioning post respectively arranged opposite each other on the upper left and upper right sides of the bracket, a telescopic mechanism for moving the suction cup left and right fixedly connected to the left side of the suction cup, a scale body with a weighing sensor fixed between the bracket and the lifting mechanism, and an inverted downward-pressing electric cylinder and a marking device fixed to the piston rod top of the downward-pressing electric cylinder arranged sequentially above the positioning post. The position sensor, weighing sensor, lifting mechanism, telescopic mechanism, suction cup, downward-pressing electric cylinder, and marking device are all electrically connected to a programmable PLC controller. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an automatic weighing and detection device for steel cylinders.

[0005] The automatic weighing and detection device for steel cylinders described in this utility model includes a control system, a base, and a detection frame. The detection frame is equipped with a lifting motor and a corresponding lifting groove. A lifting plate is slidably connected in the lifting groove. A hanging scale device is provided at the bottom of the lifting plate. A matching weighing plate is slidably connected to both sides of the hanging scale device. Both weighing plates are equipped with clamping components. A leakage detection device is provided on the lifting plate. The leakage detection device, clamping components, and lifting motor are all connected to the control system.

[0006] Working process or working principle:

[0007] In use, the cylinder is automatically gripped and placed on the base. Then, the lifting motor drives the lifting plate to descend, allowing the leak detection device to work with the cylinder. After the leak is detected, the cylinder is clamped by the clamping assembly. Then, the lifting motor drives the lifting plate to rise. The weight of the cylinder pulls the weighing plate to move within the hanging scale device, thus weighing the cylinder.

[0008] The clamping assembly includes a clamping electric cylinder fixed to the weighing plate. The cylinder rod of the clamping electric cylinder is connected to a moving plate. The weighing plate is provided with a moving groove adapted to the moving plate. A clamping block is slidably connected to the weighing plate and fixedly connected to the moving plate. The clamping electric cylinder is connected to the control system. The control system controls the operation of the clamping electric cylinder. The moving plate drives the clamping block to move within the weighing plate, and the two clamping blocks clamp the gas cylinder.

[0009] The aforementioned air leakage detection device includes an air pump fixed to the top of the lifting plate and a pressure plate fixed to the bottom of the hanging scale device. The pressure plate is provided with an air outlet pipe connected to the air pump. The air pump is connected to the control system. By inserting the air outlet pipe into the steel cylinder and pressing it with the pressure plate, the air pump is used to pump air into the steel cylinder for testing.

[0010] A support plate connects the two weighing plates, and a pressure plate is set on the support plate. When performing a gas leak detection, a certain force needs to be applied to the gas cylinder. The support plate applies the force directly instead of the hanging scale device, thus avoiding damage to the hanging scale device.

[0011] The pressure plate is equipped with a sealing gasket.

[0012] The base is equipped with a cylinder slot for easy positioning.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention can automatically pick up and place gas cylinders using an automatic gripping device, and automatically weigh and detect them through a control system. It can also perform multiple functions such as weighing and leak detection, thereby improving the detection efficiency of gas cylinders. Attached Figure Description

[0019] Example 1

[0020] like Figures 1-3As shown, the automatic cylinder weighing and detection device of this utility model includes a control system, a base 9, and a detection frame 1. The detection frame 1 is equipped with a lifting motor 2 and a lifting groove 16 corresponding to the lifting motor 2. A lifting plate 4 is slidably connected in the lifting groove 16. A hanging scale device 5 is provided at the bottom of the lifting plate 4. A matching weighing plate 8 is slidably connected to both sides of the hanging scale device 5. A clamping assembly is provided on both weighing plates 8. A leakage detection device is provided on the lifting plate 4. The leakage detection device, the clamping assembly, and the lifting motor 2 are all connected to the control system. The clamping assembly includes a clamping electric cylinder 7 fixed on the weighing plate 8. The electric cylinder rod of the clamping electric cylinder 7 is connected to a moving plate 13. A moving groove 14 matching the moving plate 13 is provided on the weighing plate 8. A clamping block 15 fixedly connected to the moving plate 13 is slidably connected in the weighing plate 8. The clamping electric cylinder 7 is connected to the control system and is controlled by the system. The system controls the operation of the clamping electric cylinder 7, which moves the clamping block 15 within the weighing plate 8 via the moving plate 13, clamping the gas cylinder using two clamping blocks 15. The gas leakage detection device includes an air pump 3 fixed to the top of the lifting plate 4 and a pressure plate 11 fixed to the bottom of the hanging scale device 5. The pressure plate 11 is equipped with an air outlet pipe 12 connected to the air pump 3. The air pump 3 is connected to the control system. By inserting the air outlet pipe 12 into the gas cylinder and pressing it with the pressure plate 11, the air pump 3 pumps air into the gas cylinder for testing. A support plate 6 connects the two weighing plates 8, and the pressure plate 11 is set on the support plate 6. When performing gas leakage detection, a certain force needs to be applied to the gas cylinder. The support plate 6 replaces the hanging scale device 5 in applying force directly, avoiding damage to the hanging scale device 5. A sealing gasket is provided on the pressure plate 11. A gas cylinder slot 10 is provided on the base 9 for easy positioning.

[0021] Working process or working principle:

[0022] In use, the cylinder is automatically gripped and placed on the base 9. Then, the lifting motor 2 drives the lifting plate 4 to descend, inserting the gas outlet pipe 12 into the cylinder and pressing it with the pressure plate 11. The air pump 3 then pumps air into the cylinder for testing. After the leak is detected, the clamping cylinder 7 moves the clamping block 15 within the weighing plate 8 via the moving plate 13. The two clamping blocks 15 clamp the cylinder. Then, the lifting motor 2 drives the lifting plate 4 to rise. The weight of the cylinder pulls the weighing plate 8 within the hanging weighing device 5, and the weight of the cylinder is weighed using the hanging weighing device 5.

[0023] This invention can automatically pick up and place gas cylinders using an automatic gripping device, and automatically weigh and detect them through a control system. It can also perform multiple functions such as weighing and leak detection, thereby improving the detection efficiency of gas cylinders.
