The main part of the composition of sealing machine sealing machine a wide range of various models of the wrapper, wrapping requirements vary, so the whole shape and structure also tend to have a greater difference, but if the program according to the product packaging and process requirements, the wrapping machine generally consists of the following major components.
(1) Packaging materials supply unit. Function packaged goods supply device is timing, in places, and regularly sent the items to be packaged packaging components. Generally, it serves as part of the packaging member is introduced. Continuously driven conveyor, high efficiency, smooth operation, often in high catch on sealer application. However, to ensure delivery and packaging motor coordination, speed of delivery device, requires synchronization and packaging components. Moreover, for a continuous-drive, the packaging material is typically formed by molding, it is difficult to achieve a multi-layer packaging and twist packaging. John intermittent belt-driven, easy to ensure coordination with the packaging operation, but work less efficient than continuous-driven, not for high-speed models
When using hopper feeding device, the lower is by pusher (with a variety of structural forms) or belt conveyor (continuous or intermittent) will be pushed to the whereabouts of goods packaging components
(2) packaging material supply means. Materials for packaging, can also be used,, roll sheets.
Coil feeding apparatus: Volume Jane-like packaging material supply roll rack mounted only by the guide roller Jane Discovery packet sent packing material position after cutting. Pull sub roll continuous and intermittent pulled pulled out two kinds, pull out the length according to the package size and packaging requirements. When the intermittent feeding, due to the barrel turn. Indignant resistance, roll may occur when moving relaxation phenomena, in order to prevent the relaxation caused due to packaging materials and warping since, generally in the package material supply device has photos tight cylinder and brake position variable tensioning roller Jane and packaging material reel brake linkage, when the cartridge is rotated feeding, tensioning rollers rose by separating the brake linkage mechanism, barrel stop feeding when the tension roller decline by interlocking mechanism, brake combination to overcome the inertia force that it no longer rotate the barrel to ensure packaging material is taut. The outer periphery of the stopper reel tape and packaging material used for start-stop operation of direct bonding, so that the volume of packaging materials change with Jane diameter, braking torque has changed.
Packaging materials can be cut or rotary shear type cutter, the former used for the case of continuous-feed. For plastic film, multi-pulse heating with a heating blade or blown to achieve cutting.
In order to make the logo on the packaging material can be in the correct position in the packaging in order to guarantee that the sulfur on the quality of gold, on a lot of sealing machines are equipped with photoelectric trademark positioning device, so that the package timber cutting position accurate. On a continuous high-speed sealing machine, continuous rotary cutter, sending the film to rely on prayer traction rollers (or feed) to ensure proper cutting speed in bits. At this point, the role of trademarks spot positioning means is this: When packing material due to fluctuations in output speed, positioning it above the mark to produce lead or lag, through a series of mechanical, electrical adjustment means changing the packaging material velocity, so that closure positioning the cut marks on the packaging material moving photoelectric device is mounted in a position to issue Hall, controlled cutting operation, marking not in place, the cutter does not operate. On some machines, pull out the packing material has a limited pot institution, when there trademarks offset, stop pulled out by changing the pattern of limiting the agency to correct the position
Sealing machine also features a lot of empty packing material to prevent the agency "no material is not feeding" or discharge blank packaging materials to ensure product quality.
Sheet material feeding device: generally the cutting of sheet material surplus in silos, pulled out a picture of the supply and delivery of parts from packaging materials.
