Description

Technical Field

[0001] The utility model relates to the technical field of edible salt filling, in particular to a filling device for finished edible salt. Background Art

[0002] The filling device for finished edible salt is a mechanical device designed to efficiently and accurately fill processed edible salt products into packaging containers. The filling device for finished edible salt is mainly composed of an automatic feeding system, a precise metering system, a filling mechanism, a packaging container conveying system and other structures. When the filling device is working, the packaging container is sent to the filling position by the conveying system, and the precise metering system automatically adjusts the conveying volume according to the preset value to fill the edible salt into the packaging container. After the filling is completed, the packaging container continues to move along the conveying system to the next process.

[0003] For example, the Chinese patent "A filling device for convenient filling of bath salts" with announcement number CN210971626U includes a device base, a hopper, a motor, a connecting rod, a first screw and a second screw. The bottom of the hopper is sleeved with a mounting plate and welded and fixed. The hopper is assembled to the top feed port of the device base through the mounting plate and bolts. The top surface of the hopper is provided with a shell, the motor is arranged in the shell, the output end of the motor is connected to the first bevel gear through a key, and the connecting rod is arranged on the top of the hopper through a bearing.

[0004] Although the above-mentioned prior art can realize the filling of salt, in actual use, on the one hand, the fixing mechanism of the filling device is not flexible enough. When using packaging bags of different specifications to fill edible salt, the packaging bag needs to be fixed to the filling device through the fixing mechanism, which results in the need to adjust the position of the fixing mechanism every time the packaging bag is replaced, thereby reducing the efficiency of the filling operation. On the other hand, it is difficult to seal the packaging bag in time after the filling of the edible salt is completed. After the filling of the edible salt is completed, the operator needs to remove the packaging bag from the filling device and then seal the head, which results in the edible salt being easily spilled during the removal of the packaging bag. Therefore, it does not meet the existing needs. In this regard, we propose a filling device for finished edible salt. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. The utility model can enable the fixing mechanism to fix packaging bags of different specifications through the screw rod and the second hydraulic telescopic device. When fixing the packaging bag, the servo motor is first turned on according to the size of the packaging, so that the output shaft of the servo motor drives the screw rod to rotate, and the screw rod drives the moving block to move in the slide groove through the external thread until the L-shaped mounting plate is moved to a suitable position through the moving block. At this time, the second hydraulic telescopic device is turned on again, so that the telescopic end of the second hydraulic telescopic device extends and drives the L-shaped mounting plate to move at the same time until the L-shaped mounting plate moves to a suitable position, and finally the third hydraulic telescopic device is turned on, so that the third hydraulic telescopic device drives the clamping plate to move through the extension of the telescopic end. At this time, the two sides of the package are respectively placed between the clamping plates on the two sides and the L-shaped mounting plate, and the clamping plate is driven by the third hydraulic telescopic device to clamp the packaging bag, thereby improving the adaptability of the fixing mechanism to packaging bags of different specifications.

[0017] 2. The utility model can heat-seal the packaging bag through the electric push rod and the heat-sealing strip. After the filling is completed, the second hydraulic telescopic device is turned on, so that the telescopic end of the second hydraulic telescopic device drives the L-shaped mounting plate to move closer to the middle of the operating table until the clamping plates on the L-shaped mounting plate contact each other and the heat-sealing strip is energized. At this time, the current passes through the resistance wire inside the heat-sealing strip, so that the resistance wire generates heat and transfers it to the surface of the heat-sealing strip. At this time, the electric push rod is turned on again, so that the telescopic end of the electric push rod pushes the heat-sealing strip to move, and the heat-sealing strips on both sides contact the packaging bag and continue to keep the heat-sealing strip moving until the heat-sealing strips contact each other, so that the packaging bag is heat-sealed, and the edible salt is prevented from being spilled during the packaging bag removal process.

[0018] 3. The utility model is provided with a first hydraulic telescopic device, which can change the height of the filling head. Before filling, the packaging bag is fixed on the fixing mechanism and the opening of the packaging bag is stretched open. At this time, the first hydraulic telescopic device is turned on to extend the telescopic end of the first hydraulic telescopic device. The extension of the telescopic end of the first hydraulic telescopic device drives the filling head to move downward until the lower end of the filling head moves to the inside of the packaging bag. At this time, the filling operation is carried out to avoid spilling of edible salt during filling. BRIEF DESCRIPTION OF THE DRAWINGS
