Packing machine packing mechanism mainly consists of folding rollers, folding fences and retaining regulatory components. When the agency will lose the carton sheet sent packing mechanism, folding roller speed given away the sheet fence, the completion of folding in cooperation with block gauges and folding rollers. The tilt angle of a folding fence is generally around 300, so that can ensure a smooth sheet into the fence, but also to reduce the size and height of the packing machine. Folding fence feed slot guides must remain parallel with the folding rollers and an appropriate distance, or not conducive to the sheet into the fence, the impact of folding work properly.
Folding fence, also known as the fence, which consists of two pieces of the fence panels and the lower fence panels. On, should ensure that the gap between the lower fence panels must be greater than 6,8 thickest carton folding machine specified thickness, so as not to hinder the carton into the fence, six general for 1. 5 mm or so. Fences should be greater than the width of the widest specified sheet size, thus ensuring the sheet on both sides of the fence and into the side of the fence there is a certain gap, and can move freely in order to avoid the sheet deflection or deflection phenomenon occurs in the fence, the impact of folding quality.
Block gauge mounted on the two fences in the middle, is used to control the folding width. According to need folding, the stopper can be regulated height adjustment and parallelism, to ensure accurate folding accuracy. Simple structure. Regulations set in the slider block by thumbscrew I fixed gear regulations claw inserted in the upper and lower fence panels are open long slot. When the sheet into the fence, retaining pawl block carton regulation, forcing the discounts were folding cartons, folding if you need to adjust the width, you must first loosen the thumbscrews, the slider is moved along the block gauge adjusted to the appropriate location and then tighten the thumbscrew complete stop regulation coarse. By rotating spinner nut 7, move the slider drive gear regulations claw movement, can be precisely regulated claw trimming gear position. Regulation on the block with a block regulation also skew adjustment mechanism to adjust the parallelism of the sheet edges blocked regulations to ensure folding accuracy.
With the application of new technologies and advanced packing machine folding fence blocking regulatory move and resize using photovoltaic technology servo motors and positioning of the grating, thereby greatly reducing the workload of the fence block adjustment regulations, improve production efficiency. Shows a schematic block regulation of electric motion control.
The principle is blocked Regulation 2 together with the toothed belt 9, 9 12 toothed belt driven by a toothed pulley movement. Toothed pulley is rotated by driving the servo motor. The backgauge; movement position and distance from the light source 10 and the grating 11 to be measured and controlled. When carrying out the actual set and mobile gear regulations, first set up by the electronic control device input block regulatory requirements set position and value, the servo motor moves the distance driven sprocket rotation settings based on the input value of the rotational movement, the tooth shaped pulley driven by a toothed belt moving, moving back and forth toothed belt drive gear regulations, determined by the accuracy of the light source and the grating position blocking movement regulation, regulation of electric moving block has the following advantages: operation, set up and easy to adjust; blanks regulatory position positioning accuracy, high precision, intuitive and strong; when the whole block regulatory adjustment saves time and effort, high efficiency; be blocked without stopping regulatory adjustments.
Folding roller is one of the important parts of the packing machine, packing machine in each group there were three folding rollers. Rollers a, b, c is a group, the roller b, c, d as a group. Since the occurrence of the folded sheet or carton thickness change frequently, which requires each pair of gaps between the folding roller is floating, and therefore, each pair of folding rollers of the folding roller has a sleeve fixed to the bearing housing while the two ends of the sleeve are the other folding roller is movable. Fixed folding rollers mounted on the frame, only a week to rotate, roll b, d is the fixed folding roller. Floating folding rollers mounted on a carriage along the chute up and down (or left and right) to move, roll a, c, spring loaded slide, due to the action of the spring, so that the folding roller between fixed and floating folding rollers remain certain very small gap (the gap should be less than the thickness of the thinnest 8 carton folding machine prescribed), and at work are folded cartons produce squeeze pressure. When the sheet is folded into the folding rollers, due to the friction of the sheet folding rollers so as to drive the sheet with the folding roller sports, and because of the role of squeezing pressure to complete folding. Floating folding roller at both ends of the spring pressure must be of moderate size, and consistent with each other, otherwise it will directly affect the accuracy of folding.
Structure of the conventional folding rollers is the use of structural steel roll steel roll, (a), the pressing force of such a structure, resistance to abrasion, but when the machine is working on the folding roller rolling noise generated by the large and less friction between the rollers and the roller of the sheet produced is not conducive to tissue folding, therefore, can not fully meet the requirements of the folding. To reduce noise, a lot of packing machine used for structural steel roller rubber roller, (b) shows, this structure greatly reduces machine noise, increasing the folding friction, but when folded tissue, sometimes crumpled paper phenomenon. In order to improve the precision folding, folding machine adopts advanced steel and plastic folding roller staggered structure, and steel, plastic parts of each pair of folding rollers relative, this structure well adapted to the folding carton thinner page. In order to obtain the appropriate friction and wear resistance, to ensure the accuracy of the folding, the folding roller for the rubber composition and hardness have certain requirements, the general use of vulcanized rubber, synthetic rubber or synthetic resin.
