1. Equipment connection and installation
Check compatibility: First, make sure that the pre-opening automatic bag is compatible with the packaging equipment. Different packaging equipment may have specific requirements for bag size, material and opening method. For example, some automatic packaging machines are suitable for pre-opening automatic bags with a width of 10-30 cm and made of polyethylene. You need to check the manual of the equipment to find out the bag specifications it supports.
Install the bag: Correctly install the pre-opening automatic bag on the packaging equipment. This may involve installing the bag reel (if it is a roll bag) on the specific axis of the equipment and ensuring that the bag can be unrolled smoothly from the reel. For some equipment with opening guide devices, the pre-opening part of the bag must be accurately inserted into the guide groove so that the equipment can smoothly grab and open the bag. For example, on some high-speed food packaging machines, the pre-opening of the bag needs to be aligned with the suction device of the equipment so that the equipment can open the bag by suction and prepare to fill the items.
2. Equipment parameter setting
Bag size parameters: Set the corresponding parameters on the packaging equipment according to the actual size of the pre-opening automatic bag. This includes the length, width and thickness of the bag. Accurate size settings ensure that the machine can accurately control the bag when grabbing, stretching and sealing. For example, if the length of the bag is set incorrectly, the machine may not seal properly after filling the items, or it may waste too much bag material.
Sealing parameters: If the packaging machine is responsible for the sealing operation, the appropriate sealing parameters need to be set. This depends on the material of the bag. For example, plastic film bags may need to set appropriate heat sealing temperature, pressure and time according to their thickness. For thinner bags, the heat sealing temperature may be around 100-130 degrees Celsius, moderate pressure, and sealing time may be 2-4 seconds; while for thicker composite bags, the heat sealing temperature may need to reach 150-200 degrees Celsius, higher pressure and 4-8 seconds of sealing time. The correct setting of these parameters can ensure the firmness and tightness of the seal.
Filling speed and accuracy: According to the characteristics of the product and the capacity of the bag, adjust the filling speed and accuracy of the packaging equipment. If the product is a small and fragile item, the filling speed may need to be slowed down 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, each tablet needs to fall accurately into the bottom of the bag, and the filling accuracy of the equipment may need to be controlled at the millimeter level.
3. Operation and monitoring
Start the equipment: After completing the installation and parameter setting, start the packaging equipment. In the early stage of equipment operation, closely observe the operation of the pre-opening automatic bag. Check whether the bag can be opened, filled with items and sealed smoothly according to the set procedures. For example, observe whether the equipment causes the bag to tear when it stretches the bag, or whether the seal is not firm during the sealing process.
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 packaging equipment has a fault alarm system that can display the operating status of the equipment 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, whether the items in the bag are filled correctly, etc. If problems are found, stop the equipment in time, adjust the parameters or troubleshoot.
4. Maintenance and adjustment
Regularly check the equipment and bag interface: In order to ensure the good cooperation between the pre-opening automatic bag and the packaging equipment, it is necessary to regularly check the connection between the equipment and the bag. For example, check whether the reel of the bag 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 the pre-opening automatic bag of different specifications or materials is replaced, the parameters of the packaging equipment need to be readjusted. This includes adjustments in bag size, sealing parameters, etc. At the same time, after the equipment has been used for a long time, due to the wear of components and other reasons, the equipment may also need to be calibrated to ensure its good cooperation with the bag.
