Heat shrink packaging machine market demand has increased significantly
A heat-shrinkable packaging machine that can perform basic functions must include: the bottle-in and bottle-out part, the main drive part, the film-wrapped part, the upper film part, the heat-shrinking furnace part, and the control part. In addition, if the tray is to be added under the package, the tray storage and transport section is also required. In addition, it may include some parts that perform other extended functions. Below, we will introduce the workflow of each part and the precautions for this part when selecting equipment.
Bottle and bottle part
The main function of this section is to deliver the product inside the machine. There are two forms of products that enter a heat-shrinkable packaging machine, namely dispersed products and products that have been packaged into small packages. Decentralized products refer to products that have not been packaged in any secondary way; while the latter are small packages that have already been packaged once by a pre-order packaging machine, and the shrink packaging machines will perform secondary packaging on these small packages.
This part can be divided into three links: into the bottle, comprehensive separation and horizontal forming.
The bottle is delivered to the packaging machine and belongs to the conveyor line. In general, this part is also adjusted and controlled by the packaging machine. The key to the bottle entry part is the adjustment of the speed. A good packaging machine can be delivered without pressure, and its speed can also change with the speed of the dispensing bottle. In order to ensure that the squeeze bottle or the excessive looseness of the bottle does not occur during the entire cycle of finger dispensing, this function is particularly important for the packaging of non-gasified beverages.
The hedging component is a series of products that are fed into the bottle and are divided into multiple directions according to the requirements of the package form. The general situation consists of several suspended stainless steel partitions and positioning devices for these partitions. When using and purchasing machinery, the following two points should be noted in this link: First, if the partition plate is a stainless steel plate, be sure to pay attention to its imported guiding device. If the handling is not good, there may be imported scratched packaging trademarks or Damage to the packaging. Secondly, the positioning devices for these partitions currently have three forms. The earliest is to divide and fix the partition plate by a certain distance from the column block. This form has the advantages of low cost, but the disadvantage is also very obvious. It is the time for converting the production product is too long, the labor intensity is too large to meet the modern production. The need for equipment flexibility. At present, a more practical method is to set a manual adjustment wheel at each positioning device, so that only a small amount of cost can be added to shorten the conversion time, and the conversion can be completed without too complicated operation. Now, the most advanced part of the separation is completely completed by the servo motor, as long as the conversion of the variety conversion program is completed on the operation panel, the equipment will be automatically converted to the spacing of the new production variety, but the cost of the equipment is too high.
The horizontal forming section separates the longitudinally-separated products into rows in accordance with the packaging requirements. The old way was to use pneumatically controlled pneumatic doors to separate them. This way the speed cannot be too fast. However, this method is also applied in the repackaging of small packages into large packages, that is, using a pressure plate controlled by an air cylinder. Most of the machines nowadays use a set of bottle fingers driven by a pair of servo motors. This method controls the movement of two servo motors and adjusts the distance between the components of a bottle to complete the pair. Product separation. The well-designed bottle separation means that it can basically complete the packaging of all products with only one set of bottle points, and it is not necessary to replace the bottle separation index every time it is replaced. Another advantage of the bottle separation is that after separation You can also send a product forward until the next process.
