How To Use Pre-Opened Bags With Auto Bag Equipment ？

(1) Equipment connection and installation

1. Check compatibility: Confirm that the pre-opened bag is compatible with the auto bag equipment. Different equipment has specific requirements for bag size, material and opening method. You need to check the equipment manual to understand the bag specifications it supports. For example, some equipment is suitable for pre-opened bags with a specific width range (such as 10-30 cm) and material (such as polyethylene).

2. Install the bag: If it is a roll-loaded pre-opened bag, install the bag roll on the specific axis of the equipment to ensure that the bag can be smoothly unrolled from the roll. For equipment with an opening guide device, the pre-opening part must be accurately inserted into the guide groove. For example, some high-speed packaging machines need to align the pre-opening of the bag with the suction device of the equipment so that the equipment can open the bag through suction and prepare for loading.

(2). Equipment parameter setting

1. Bag size parameters: According to the actual size of the pre-opened bag, set the corresponding parameters on the equipment, including length, width and thickness. Accurately setting the size allows the equipment to accurately control the bag when grabbing, stretching and sealing. For example, incorrect bag length setting may result in improper sealing after filling or waste of bag material.
2. Sealing parameters: If the equipment is responsible for the sealing operation, the appropriate sealing parameters need to be set according to the bag material. For example, for plastic film bags, the heat sealing temperature, pressure and time need to be set according to its thickness. For thinner bags, the heat sealing temperature may be 100-130 degrees Celsius, the pressure is moderate, and the sealing time is 2-4 seconds; for thicker composite bags, the heat sealing temperature may need to reach 150-200 degrees Celsius, the pressure is higher, and the sealing time is 4-8 seconds. Correctly setting these parameters can ensure a firm and tight seal.
3. Filling speed and accuracy: Adjust the filling speed and accuracy of the equipment according to the product characteristics and bag capacity. If the product is small and fragile, slow down the filling speed to avoid damaging the product; at the same time, ensure that the equipment can accurately fill the product into the appropriate position of the bag. For example, when packaging medicines, the filling accuracy needs to be controlled at the millimeter level so that each tablet falls accurately into the bottom of the bag.
(3) Operation and monitoring
1. Start the equipment: After completing the installation and parameter setting, start the auto bag equipment. In the early stage of equipment operation, closely observe the operation of the pre-opened bag and check whether the bag can be opened, loaded and sealed smoothly according to the set program. For example, observe whether the equipment causes tearing when stretching the bag and whether the seal is firm during the sealing process.
2. Real-time monitoring: During the operation of the equipment, continuously monitor the various indicators of the equipment and the packaging quality of the bag. Some advanced equipment has a fault alarm system that can display the equipment operation status in real time, such as abnormal temperature, insufficient pressure, etc. At the same time, check whether the packaged bags meet the quality standards, such as whether the seal is flat and whether the items in the bag are filled correctly. If problems are found, stop the equipment in time, adjust the parameters or troubleshoot.

(4) Maintenance and adjustment

Regularly check the interface between the equipment and the bag: To ensure that the pre-opened bag and the equipment work well together, it is necessary to regularly check the connection between the equipment and the bag. For example, check whether the bag roll can rotate smoothly and whether the opening guide device is blocked or worn. If it is found that the bag does not run smoothly on the equipment, it may be necessary to clean or replace the relevant parts.
Adjust the equipment according to bag changes: If you change the pre-opened bag of different specifications or materials, you need to readjust the equipment parameters, including bag size, sealing parameters, etc. In addition, after long-term use, the equipment may also need to be calibrated due to component wear and other reasons to ensure a good fit with the bag.
