Because two sets of transverse sealing and cutting mechanisms are used alternately and repeatedly, the double-yield of the original similar equipment is realized;

5. the semi-finished product supporting mechanism comprises a supporting rod 36, a supporting connecting rod 37, a supporting eccentric wheel 38 and a supporting rotary power source 39. Because the machine is designed with two sets of transverse sealing and cutting mechanisms for improving the yield, when one group of clamping packaging bag openings are sealed and cut, and the packaging bag horizontally moves to an upper part and a lower part for separation, the material is stored and a semi-finished product (also called a finished product) after the heat sealing and cutting sinks without a support, so that the machine is designed, and when the upper heat sealing knife and the lower heat sealing knife are separated (a prefabricated bag of the material stored in the later group is a semi-finished product, and the machine is designed without a support and sinks), the upper end of a supporting rod 36 of the semi-finished product supporting mechanism is rotatably supported by a supporting rotary power source 39 to rotatably support an eccentric wheel 38 and is acted by a supporting connecting rod 37 to support the semi-finished product; when the next group of upper and lower heat sealing knives and the like are folded and perform heat sealing movement to 2/3 of the stroke, 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 to allow the group of upper and lower heat sealing knives and the like to pass through, and the expected effect is realized by the repeated alternating continuous operation;

6. the finished product discharging mechanism comprises a discharging rotary power source 40, a discharging conveying belt assembly 41, a discharging horizontal regulator 42 and a discharging up-down regulator 43. The discharging conveyor belt assembly 41 is adjusted to the optimal position of the upper, lower, left and right (the material bearing plane on the discharging conveyor belt assembly can be finely adjusted within 20mm, and the left and right can be adjusted within 60-150 mm) through a discharging up-down adjuster 43 and a discharging level adjuster 42, and is driven by a discharging rotary power source 40 to convey the finished packaging bag to the required place at a speed slightly higher than the linear speed of the whole machine (the speed can be adjusted and controlled arbitrarily).

The installation, connection and operation functions of the relevant parts of each process are as follows:

step one, a blanking conveying mechanism: as shown in fig. 1 and 2, the blanking device 3 is arranged on a left platform of a plane where the materials of the whole machine run, the power source 2 of the blanking device is arranged on the left side of the blanking device 3, the blanking device 3 is driven by the power source 2 of the blanking device to put down the materials according to the required number of versions and put into one of the spacer-attached synchronous belt assemblies 6 (PE engineering plastic material synchronous belts replace chains, so that the noise of the parts is effectively avoided), the blanking rotary power source 7 is arranged under the platform at the inner end of the spacer-attached synchronous belt assemblies 6, and the spacer-attached synchronous belt assemblies 6 directly drive the materials to the bag former through a synchronous wheel (a batch of mechanical parts for long-distance transfer transmission are omitted) at the linear speed required by the version length. The distance between the spacers of the synchronous belt component 6 with the spacers is the longest product of a user, when a packaged object is changed along with the change of the bag length or the distance, the linear speed can be adjusted and controlled at will by adjusting the rotating speed of the power source 4 of the material supplementing device, and the difference of the long bag and the short bag is delayed or tracked (the synchronous belt components with different spacer distances do not need to be replaced). Particularly, the synchronous belt component 6 with the spacer is made of PE engineering plastics, replaces a chain in the original equipment, and can effectively avoid the noise of the component;

step two, a film traction longitudinal sealing mechanism: as shown in fig. 1, the drawing roller rotating power source 10 is arranged on the upper wall of the main machine housing 1, the drawing roller 9 with the outer circumference provided with the reticulate pattern is directly connected with the drawing roller rotating power source 10, the drawing roller 9 and the press roller are directly driven by the drawing roller rotating power source 10 to send the film to the bag former, the material (forming the pre-packaging bag with the material) sent into the bag former in the same process is directly driven by the drawing wheel 12 (two pieces) by the drawing wheel rotating power source 11 to be sent into the longitudinal sealing heater 13 for heating, and synchronously moves forward to the position between the longitudinal sealing embossing wheels 15 (two pieces), the longitudinal sealing embossing wheels 15 are directly driven by the longitudinal sealing embossing wheel rotating power source 14 to synchronously thermally extrude the patterns at the longitudinal sealing position of the pre-packaging bag and send the patterns into the pre-packaging bag clamping and sending mechanism;

step three, a prefabricated bag clamping and conveying mechanism: as shown in fig. 1 and 2, the upper and lower adjusters 19 and 18 are mounted on the inner wall of the main housing 1, and the upper and lower pinch friction belt assemblies 20 (upper and lower sets) are mounted on the upper and lower adjusters 19 and 18, respectively. The distance between the pinch friction belt components 20 at the upper and lower positions is respectively controlled by an upper adjusting hand wheel of an upper adjuster 19 (which can be lifted by 70 mm) and a hand wheel of a lower adjuster 18 (which can be finely adjusted by 10 mm) to be adjusted to an optimal state suitable for clamping according to the requirement of bag thickness change, then the pinch friction belt components are driven by an upper pinch rotary power source 17 and a lower pinch rotary power source 16 in opposite directions, and a packaging bag with materials in the clamping traction moves forwards horizontally according to the required direction and linear speed and is sent to a transverse sealing cutting mechanism (capable of meeting the requirement of traction packaging of materials with different bag thicknesses of 5-80 mm). The structure is simple and the application is reliable;

step four, a transverse sealing and cutting mechanism (the main key device of the invention): as shown in fig. 1 to 4, two sets of transverse sealing and cutting mechanisms are designed for realizing high-speed production, and are respectively arranged at the inner sides of the front and rear main machine housing windows. 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 are separated in an upper and lower parabolic shape along the backward return side, when the valve returns to a half stroke, the valve is closed in a lower and upper parabolic shape while continuing to return backwards, then clamping the subsequent bag mouth for sealing, cutting and horizontally moving to the end point, and circularly making an upper movement track A and a lower movement track A which are parabolic; 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 from the upper and lower oblique lines along the backward return edge, when the bag returns to a half stroke, the bag is continuously folded in a downward and upward oblique line shape while returning to the back, then the bag opening is clamped, sealed, cut and horizontally moved forward to the terminal point, and an upper triangular movement track C and a lower triangular movement track C are circularly and circularly performed. The three operation modes can be selected according to the shape of the packaged object, and the three operation modes are circularly and circularly moved to clamp the bag mouth for sealing and cutting, and transversely move the finished product forward to send the finished product to the finished product discharging mechanism so as to realize the aim of the invention.

When the transverse sealing and cutting mechanisms are two sets: the upper and lower heat-sealing cutters and the cutting knife of the previous 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 cutters and the cutting knife, the bag mouth of the packaging bag is sealed and cut while being closed, and the transverse sliding table is controlled by a transverse driving power source to drive the packaging bag to transversely move forwards at a constant speed rightward; 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 first 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 upper and lower parabolas of the subsequent bag mouth are clamped to horizontally move forward to form a parabola motion 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 opening for sealing, cutting and horizontally moving forward, then the back return path is sequentially separated from the upper oblique line and the lower oblique line (about 1/3 of the return path), then the horizontal return path (about 1/3 of the return path) is carried out, then the lower oblique line and the upper oblique line are folded (about 1/3 of the return path), and the upper and the lower two of the subsequent bag openings are clamped to horizontally move forward and take the 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 upper and lower oblique lines are separated and the lower and upper oblique lines are folded in the backward return process, and the subsequent bag opening is clamped to horizontally move forward, and the upper and lower bags 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.

Violently seal and cut off relation between upper and lower hot seal sword and the cut-off knife in the mechanism: 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 as to enable the prefabricated bag (semi-finished product) to move horizontally to the finished product discharging mechanism. When the other set of transverse sealing and cutting mechanisms close and seal to move to 2/3 of the stroke, the upper end of the supporting rod 36 is rapidly moved downwards under the action of the supporting rotary power source 39, the supporting eccentric wheel 38 and the supporting connecting rod 37, and 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.

When the automatic discharging device works, the upper plane of the discharging conveying belt component 41 is adjusted to be slightly lower than the bottom of a finished product by the hand wheel of the discharging up-down adjuster 43, the discharging conveying belt component is adjusted to be at the left-right optimal position by the adjusting hand wheel of the discharging level adjuster 42, then the discharging conveying belt component 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 containers.

The invention relates to a full-servo high-speed pillow type packaging machine, wherein each mechanism part macroscopically adopts up to 14 rotary power sources which are modern advanced transmission devices such as a servo motor, a PE engineering plastic synchronous conveyor belt component and the like and each part direct-drive method, so that a batch of traditional mechanical devices such as chain wheels, chains, tension wheels, gears and the like for remote transfer transmission are omitted, the equipment transmission mechanism is effectively simplified, the working noise is reduced, and the operation speed and the operation 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.
