Every group respectively is equipped with horizontal side to side movement parts and upper and lower vertical opening and shutting movement parts and implements, now with one set and two sets of horizontal seal cutting mechanism's operation step respectively describe as follows:
when the horizontal sealing and cutting mechanism is one set: when the machine is started, the upper and lower heat- sealing knives 30, 32 and the cutter 31 are controlled by the transverse driving power source 23 and the longitudinal driving power source 25, the bag opening of the packaging bag is clamped, heat sealing and cutting are carried out while the horizontal transverse advancing of the long stroke of the packaging bag is carried out at the same line speed with the whole machine (each stroke is used for sealing and cutting the packaging bag, the upper and lower heat- sealing knives 30, 32 in each stroke of the invention are used for clamping the bag opening of the packaging film for heat sealing, the sealing time is more than five times of the sealing time of the traditional known technology, and the problem of poor sealing of the originally designed packaging bag opening is thoroughly solved). When the finished product is at the end point, the finished product is sent to a finished product discharging mechanism and then returns, and the return has various operation modes as shown in figure 4. The first method is as follows: the upper and lower heat sealing knives and the cutter knife are separated in a way of being in which being in a way of being in which being in a way of being in which being in a way of being in which; the second method comprises the following steps: the upper and lower heat sealing knives and the cutter are separated in an upper and lower oblique line shape along the backward return path, the horizontal return is changed when the upper and lower heat sealing knives and the cutter return for a certain stroke, the lower and upper oblique line shape is folded while continuing the backward return path when the upper and lower heat sealing knives and the cutter return for a certain stroke, the subsequent bag mouth is clamped for sealing and cutting, the bag is horizontally moved to the terminal point, and the upper and lower two motion tracks B in a trapezoid shape are circularly and circularly carried out; the third method comprises the following steps: the upper and lower heat sealing knives and the cutter are separated in an upper and lower oblique lines along the backward return path, and are continuously folded in a lower and upper oblique lines along the backward return path when the upper and lower heat sealing knives and the cutter return to a half stroke, then the bag mouth is clamped for sealing, cut and horizontally move to the terminal point, and the upper and lower triangular movement tracks C are repeatedly and circularly made. The three operation modes can be selected according to the shape of the object to be packed, and the object of the invention is realized by circularly and circularly moving, continuously clamping the bag mouth for sealing, cutting and transversely forwarding the finished product to a finished product discharging mechanism.
When the transverse sealing and cutting mechanisms are two sets: the upper and lower heat sealing knives and the cutting knife of the former set of transverse sealing and cutting mechanism are controlled by a longitudinal driving power source to drive the upper and lower longitudinal sliding tables, the upper and lower heat sealing knives and the cutting knife, the bag mouth of the packaging bag is sealed and cut while the transverse driving power source controls the transverse sliding table to drive the transverse sliding table to move forwards at a constant speed in the right and transverse directions; meanwhile, the upper and lower heat sealing knives and the cut-off knife of the latter set of transverse sealing cutting mechanism are controlled by a longitudinal driving power source, the upper and lower longitudinal sliding tables drive the edge to be separated, the transverse sliding table is controlled by a transverse driving power source to drive the left to return, when the return is half (the distance separating the upper and lower heat sealing knives of the set is just the right transverse forward passing of the upper and lower heat sealing knives, the cut-off knife and the upper and lower brackets of the latter set in a closed state), then the left end edge is closed while the return is continued, and finally the subsequent packaging bags with materials are clamped and pulled to move forwards transversely at a uniform speed right. The two sets of transverse sealing and cutting mechanisms can adopt three operation modes (the former operation is the starting point) as shown in figure 4 according to the condition of the packaged object. The first method is as follows: the upper and lower heat sealing knives and the cutting knife are folded to clamp the bag mouth of the packaging bag for sealing, cutting and horizontally moving forward, then the upper and lower parabolas are separated (the first half section) and the lower and upper parabolas are folded (the second half section) in sequence in a backward stroke, and the subsequent bag mouth of the packaging bag is clamped to horizontally move forward, and the upper and lower parabolas form a parabola-shaped movement track A; the second method comprises the following steps: the upper and lower heat-sealing knives and the cutting knife are firstly folded to clamp the bag mouth for sealing, cutting and horizontally moving forward, then the back return path is sequentially separated in an upper oblique line shape and a lower oblique line shape (about the return path 1/3), then the horizontal return path (about the return path 1/3) is carried out, then the lower oblique line shape and the upper oblique line shape are folded (about the return path 1/3), and the upper and lower two of the subsequent bag mouth are clamped to horizontally move forward to form a trapezoidal motion track B; the third method comprises the following steps: the upper and lower heat sealing knives and the cutting knife are firstly folded to clamp the bag opening for sealing, cutting and horizontally moving forward, then the bag opening is separated in an upward and downward oblique line shape and folded in a downward and upward oblique line shape in a backward return process, and the subsequent bag opening is clamped to horizontally move forward, so that the upper and lower bag openings form a triangular movement track C. The three operation modes can be selected according to the shape of the packaged object, the optimal mode is adopted, the continuous alternate and cyclic motion is carried out, and the packaged and cut products are sent to a finished product discharging mechanism in sequence, so that the production efficiency of the invention is twice of that of the original equipment.
The relationship between the upper and lower heat sealing knives and the cutting knife in the transverse sealing and cutting mechanism is as follows: as shown in fig. 1, 3 and 4, the upper and lower supports 29, 33 are respectively mounted on the upper and lower longitudinal sliding tables 28, 35, the cutting knife 31 is mounted below the upper support 29, the upper heat seal knife 30 is suspended around the cutting knife 31 at a position about 5mm below the upper support 29 by being pressed by a spring in a non-operating state, a knife edge (tip) of the cutting knife is at a position about 2.5mm of a lower heat seal surface of the upper heat seal knife, and the lower heat seal knife 32 is mounted on the lower support 33. When the upper heat-sealing knife 30 moves downwards under the action of the spring and contacts the packaging bag (film) first to seal the bag opening, the knife edge (knife tip) of the cutter 31 continues to move downwards to the lower heat-sealing surface of the upper heat-sealing knife 30 to start cutting into the packaging bag (film), and when the upper heat-sealing knife 30 and the lower heat-sealing knife 32 are closed and pressed, the knife edge of the cutter 31 naturally cuts into about 2.5mm, so that the effect of stably cutting the packaging bag at the front position and the rear position is achieved, and additional transmission parts and power sources required by the original cutter are reduced.
Step five, a semi-finished product bearing mechanism: as shown in fig. 1 to 3, the semi-finished product supporting mechanism is installed on a bottom plate of the machine, a supporting rotary power source 39 is installed on one side of a box body, a supporting eccentric wheel 38 is directly installed at the shaft end of the supporting rotary power source 39, a supporting rod 36 is installed in a movable sleeve in the upper end of the box body in a floating mode, two ends of a supporting connecting rod 37 are respectively connected with the supporting eccentric wheel 38 and the supporting rod 36, and when the supporting rotary power source 39 directly drives the supporting eccentric wheel 38 to rotate, the supporting connecting rod 37 drives the supporting rod 36 to do up-and-down reciprocating motion (the stroke is about 150mm adjustable). Because the invention has two sets of transverse sealing and cutting mechanisms which operate alternately, when one set of sealing and cutting mechanisms is separated, the prefabricated bag (semi-finished product) can sink, so that the supporting rod 36 of the mechanism can be rotated by the supporting rotary power source 39 and the supporting eccentric wheel 38 and can instantaneously move upwards to support the tail end prefabricated bag (semi-finished product) through the action of the supporting connecting rod 37, so that the tail end prefabricated bag (semi-finished product) can be horizontally moved forwards to the finished product discharging mechanism. When the other set of transverse sealing and cutting mechanisms close and seal to 2/3 strokes, the upper end of the supporting rod 36 is acted by the supporting rotary power source 39, the supporting eccentric wheel 38 and the supporting connecting rod 37 to rapidly move downwards, and then the latter set of transverse sealing and cutting mechanisms pass through, so that the expected effect is realized by alternately and continuously operating in cycles. Because the service is two sets of transverse sealing and cutting mechanisms, the operation speed of the pillow type packaging machine is twice of that of the original pillow type packaging machine;
step six, a finished product discharging mechanism: as shown in fig. 1 to 3, the product discharging mechanism includes an interconnected discharging conveyor belt assembly 41, a discharging rotary power source 40, and a discharging up-down regulator 43 and a discharging level regulator 42. The discharging horizontal regulator 42 (with a hand wheel) is arranged on the inner wall of the main machine housing 1, the discharging upper and lower regulator 43 (with a hand wheel) is arranged on the discharging horizontal regulator 42, and the discharging conveying belt component 41 is arranged on the discharging upper and lower regulator 43. The height of the upper plane of the discharging conveying belt component 41 can be adjusted by a hand wheel of the discharging up-down adjuster 43, the height of the hand wheel of the discharging horizontal adjuster 42 can be correspondingly adjusted by 90mm along with the change of the length stroke of the bag, and the packaging requirements of different bag lengths of 60-150mm can be met. When the device works, the upper plane of the discharging conveying belt assembly 41 is adjusted to a position slightly lower than the bottom of a finished product by the hand wheel of the discharging up-down adjuster 43, the discharging conveying belt assembly is adjusted to the left-right optimal position by the adjusting hand wheel of the discharging level adjuster 42, then the discharging conveying belt assembly is directly driven by the discharging rotating power source 40 to move forward slightly faster than the linear speed of the whole machine, and the cut finished product is smoothly sent to post-process equipment or a container.
The invention relates to a full-servo high-speed pillow type packaging machine, wherein each mechanism part macroscopically adopts up to 14 rotating power sources, namely a servo motor, a PE engineering plastic synchronous conveyor belt component and other modern advanced transmission devices and each part direct-drive method, so that a batch of chain wheels, chains, tension wheels, gears and other traditional mechanical parts for long-distance transfer transmission are omitted, the equipment transmission mechanism is effectively simplified, the working noise is reduced, and the operation speed and precision are improved. All servo motors are uniformly regulated and controlled by a microcomputer control mechanism 44 (adopting a programmable controller program for control), and the running speed of each mechanism and machine parts can be regulated and controlled by any programmable program, so that the running time, the rotating speed, the stroke, the linear speed and the like of each mechanism can be perfectly and randomly set and coordinated, the packaging requirements of diversified products with different lengths, widths and thicknesses can be met, and the performance of the pillow type packaging machine is far superior to that of the existing pillow type packaging machine.
