Utility Model Content

[0004] The purpose of this invention is to provide a small-capacity refrigerant metering device to solve the technical problem of low filling efficiency in the existing automated filling process on conveyor belts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A small-capacity refrigerant metering filling device includes a base, a workbench on the top of the base, a fixing mechanism for industrial refrigerant filling, a conveyor belt device, a controller and a U-shaped frame respectively installed on the top of the workbench, an electric cylinder installed on the top of the U-shaped frame, a metering device installed at the end of the telescopic rod of the electric cylinder, and a filling head installed at the bottom of the metering device.

[0006] The above solution, by installing a fixed mechanism, conveyor belt device, and electric cylinder on the top of the workbench, and under the control of the controller, fixes the industrial refrigerant filling bottles placed on the conveyor belt device, thereby aligning the filling head at the end of the electric cylinder telescopic rod with the industrial refrigerant filling bottle, thus accurately filling it, greatly improving the stability of the equipment during filling and significantly increasing work efficiency.

[0007] As a further embodiment of this utility model, the fixing mechanism includes a base box, which is installed below the conveyor belt device. A bidirectional screw is rotatably connected inside the base box, and clamps are symmetrically screwed onto the surface of the bidirectional screw. The clamps extend to the top of the conveyor belt device, and one end of the bidirectional screw passes through the base box and is equipped with a motor.

[0008] By adopting the above technical solution: by setting up a fixing mechanism, the motor drives the bidirectional screw to rotate, which in turn drives the grippers to move relative to each other, thereby fixing the industrial refrigerant filling bottle and enabling the filling head to accurately align with it, thus greatly improving the stability of the equipment and making the filling process more stable.

[0009] As a further embodiment of this utility model, the grippers are symmetrically provided with diamond-shaped clamping openings to clamp and fix filling bottles of different sizes, so that the filling bottles of industrial refrigerant are kept in the same state as the filling head for subsequent filling.

[0010] As a further embodiment of this utility model, guide blocks are symmetrically installed on one side of the gripper to guide the industrial refrigerant filling bottle placed on the conveyor belt device and gather it towards the center, so that the gripper can fix it later.

[0011] As a preferred embodiment of this utility model, the fixing mechanism is vertically arranged below the conveyor belt device to reduce the space occupied by the equipment and effectively control the cost while ensuring high performance.

[0012] As a further preferred embodiment of this utility model, the controller is electrically connected to the motor, electric cylinder and conveyor belt device through wires to achieve synchronization, thereby enabling safe and stable filling of industrial refrigerant.

[0013] Compared with the prior art, the advantages of this utility model's small-capacity refrigerant metering filling device are as follows: A fixed mechanism, conveyor belt device, and electric cylinder are installed on the top of the workbench. Under the control of the controller, the industrial refrigerant filling bottles placed on the conveyor belt device are fixed, so that the filling head at the end of the electric cylinder telescopic rod is aligned with the industrial refrigerant filling bottle, thereby accurately filling it, greatly improving the stability of the equipment during filling and significantly increasing work efficiency.

[0021] The fixing mechanism 6 includes a base box 601, which is installed below the conveyor belt device 5. A bidirectional screw 602 is rotatably connected inside the base box 601. Clamping jaws 603 are symmetrically screwed onto the surface of the bidirectional screw 602, extending above the conveyor belt device 5. One end of the bidirectional screw 602 passes through the base box 601 and is fitted with a motor 604. By setting up the fixing mechanism 6, the motor 604 drives the bidirectional screw 602 to rotate, which in turn drives the clamping jaws 603 to move relative to each other, thereby fixing the industrial refrigerant filling bottle and ensuring precise alignment of the filling head 403. This significantly improves the stability of the equipment and makes filling more stable.

[0022] The gripper 603 has symmetrically arranged diamond-shaped clamping openings 605 to clamp and fix filling bottles of different sizes, so that the filling bottle of industrial refrigerant is in the same state as the filling head 403 for subsequent filling.

[0023] Guide blocks 606 are symmetrically installed on one side of the gripper 603 to guide the industrial refrigerant filling bottles placed on the conveyor belt device 5 and gather them towards the center, so that the gripper 603 can fix them later.

[0025] The controller 3 is electrically connected to the motor 604, the electric cylinder 401, and the conveyor belt device 5 via wires. The controller 3 controls the operation, thereby ensuring safe and stable filling of industrial refrigerants. The controller 3 can be a Siemens S7-300 series PLC controller. The metering device 402 uses a high-precision flow controller, model ACU20FD-L. The conveyor belt device 5 is a mature existing technology and will not be described in detail here.

[0026] In this embodiment of the invention, the controller 3 controls the conveyor belt device 5, the electric cylinder 401, the motor 604, and the metering device 402 to operate synchronously. At the same time, the industrial refrigerant storage tank is placed on the conveyor belt device 5. The gripper 603 on the fixing mechanism 6 is fixed to the refrigerant storage tank under the drive of the motor 604, so that the filling head 403 docks with the refrigerant storage tank under the drive of the electric cylinder 401, thereby performing the filling operation. This greatly improves the stability of the equipment during filling and significantly increases work efficiency.

[0027] In summary, this utility model embodiment, by installing a fixing mechanism 6, a conveyor belt device 5, and an electric cylinder 401 on the top of the workbench 2, and under the control of the controller 3, fixes the industrial refrigerant filling bottle placed on the conveyor belt device 5, thereby aligning the filling head 403 at the end of the telescopic rod of the electric cylinder 401 with the industrial refrigerant filling bottle, thus accurately filling it, greatly improving the stability of the equipment during filling and significantly increasing work efficiency.
