Description

Technical Field

[0001] The invention relates to automatic bag packaging equipment, in particular to a pillow packaging machine which uses a film to wrap articles to form a pillow-shaped packaging bag. Background Art

[0002] Pillow packaging machines are used in the food, medicine, tableware and other industries to pack candies, medicine plates, small devices and disposable tableware in outer bags. With the development of society, various industries have continuously improved their requirements for production efficiency and environment, thus putting forward strong requirements for the improvement of existing pillow packaging machines. It is well known that traditional pillow packaging machines use chains to convey materials into the film bin, and a group of heat-sealing and cutting mechanisms (key components of the machine) are driven by gears and eccentric wheels to move up and down and offset to instantly seal and cut. It has the disadvantages of complex structure, high noise, short heat sealing time, poor bag sealing, low production efficiency, etc., which can no longer meet the various requirements of high-end users. Summary of the invention

[0003] The purpose of the present invention is to solve the above technical deficiencies of the existing pillow packaging machine and provide a high-speed intelligent pillow packaging machine, simplify the structure, reduce working noise, increase the heat sealing time, make the bag opening (i.e. the upper and lower films) of the packaging bag fit firmly, and improve production capacity.

[0004] The purpose of the present invention is achieved through the following technical solutions: a high-speed intelligent pillow packaging machine, comprising a main engine arch, on which a material conveying mechanism, a film pulling mechanism, a film pulling longitudinal sealing mechanism, a material guiding mechanism, and a finished product discharging mechanism are sequentially installed, a transverse driving power source is installed on the main engine arch and between the material guiding mechanism and the discharging mechanism, a transverse slide is installed on the transverse driving power source, and upper and lower longitudinal driving power sources are installed on the transverse slide, and an upper longitudinal slide is installed on the upper part of the upper and lower longitudinal driving power sources, and a lower longitudinal slide is installed on the lower part, and an upper heat sealing knife is installed on the upper longitudinal slide through an upper bracket, and a lower heat sealing knife is installed on the lower longitudinal slide through a lower bracket. A cutting knife is installed on the upper bracket and in the upper heat sealing knife, and the cutting edge of the cutting knife is above the upper heat sealing knife.

[0005] The transverse driving power source, the transverse slide, the upper and lower longitudinal driving power sources, the upper longitudinal slide, the upper bracket, the upper heat sealing knife, the cutting knife, the lower longitudinal slide, the lower bracket, and the lower heat sealing knife constitute a heat sealing and cutting mechanism. The main machine archway includes a main machine archway placed in the front position and a rear position. The heat sealing and cutting mechanism consists of two sets, which are respectively installed on the inner sides of the main machine archways placed in the front position and the rear position. The two sets of heat sealing and cutting mechanisms are used alternately.

[0006] The overall operation process of the present invention is as follows: first, the spacer synchronous belt assembly of the material conveying mechanism is driven by the material conveying rotary power source, and the material is fed into the bag former at a linear speed according to the plate length requirement; second, the traction roller of the film traction mechanism is driven by the traction roller rotary power source, and the film is pulled forward synchronously into the bag former; third, the traction wheel of the film traction longitudinal sealing mechanism is directly driven by the traction wheel rotary power source to synchronously pull the film into the longitudinal sealing knife for heat sealing, and the longitudinal sealing embossing wheel is directly driven by the embossing wheel rotary power source to synchronously heat-press the longitudinal sealing pattern and deliver the prefabricated bag into the material feeding mechanism; fourth, the material feeding friction belt assembly of the material feeding mechanism is driven by the material feeding rotary power source The heat sealing and cutting mechanism is driven by a power source to pull the packaging bag containing the material into the heat sealing and cutting mechanism; fifthly, the transverse driving power source, transverse slide and upper and lower longitudinal driving power sources, upper and lower longitudinal slides (double slide mode) of the heat sealing and cutting mechanism respectively drive the upper and lower heat sealing knives and cutting knives to close, clamp the bag mouth to seal and cut, move forward horizontally, separate and return up and down, and then close again in a cycle, clamp the packaging bag horizontally, move forward, seal and cut, and send the finished product to the finished product discharging mechanism at the same time; finally, the discharging conveyor belt assembly of the finished product discharging mechanism is driven by the discharging rotating power source to transport the finished packaging bag to the required location at a speed slightly faster than the line speed of the whole machine.

[0007] The material conveying, film traction, film traction longitudinal sealing, material guiding, and finished product discharging mechanisms of the present invention all adopt modern advanced transmission devices such as rotary power source (all disc servo motors), lateral drive power source in heat sealing and cutting mechanism, upper and lower longitudinal drive power source, and discharging lateral adjustment drive power source of finished product discharging mechanism (all linear servo motors), and replace a batch of traditional mechanical parts such as sprockets, chains, tension wheels, gears, eccentric wheels, etc. with direct drive method of each part. Compared with the existing pillow packaging machines of various models, the transmission mechanism of the equipment is effectively and thoroughly simplified, the working noise is reduced, the sealing effect of the bag mouth of the packaging bag is improved, and the operating speed and accuracy are improved. In particular, two sets of heat sealing and cutting mechanisms are designed to double the working efficiency of the equipment, and the existing pillow packaging machine is completely transformed and improved, achieving a leap in quality and quantity. The programmable controller is used for program control, so that the running time, rotation speed, stroke and line speed of the above-mentioned mechanisms can be set arbitrarily, which is suitable for packaging products of different length specifications, and the performance is far better than the existing pillow packaging machine. It can meet the urgent requirements of users for high-speed production, cost reduction and optimization of working environment, and can realize the flexible and diversified packaging needs of users for different products. It is an unprecedented innovative product in the known pillow packaging machines. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific implementation methods.

[0013] Reference Figures 1 to 4 It can be seen that the high-speed intelligent pillow packaging machine of the present invention comprises a main frame 1, on which are arranged in sequence (from left to right) a material conveying mechanism (including a spacer synchronous belt assembly 2, a material conveying rotating power source 3), a film traction mechanism (including a traction roller 4, a traction roller rotating power source 5), a film traction longitudinal sealing mechanism (including a traction wheel rotating power source 6, a traction wheel 7 and a longitudinal sealing knife, an embossing wheel rotating power source 8, and a longitudinal sealing embossing wheel 9), a material guiding mechanism (including a material guiding friction belt assembly 10, a material guiding rotating power source 13, a material guiding upper regulator 12, and a material guiding lower regulator 11), a finished product discharging mechanism (including a discharging level regulator 27, a discharging lower regulator 11, and a discharging level regulator 28). A regulator 26, a discharging conveyor belt assembly 24), a transverse driving power source 14 (a transverse driving linear servo motor) is installed on the main engine arch 1 (the inner side thereof) and between the feeding mechanism and the discharging mechanism, a transverse driving power source 14 is installed with a transverse slide 15, and an upper and lower longitudinal driving power source 16 (an upper and lower longitudinal driving linear servo motor) is installed on the transverse slide 15, an upper longitudinal slide 17 is installed on the upper part of the upper and lower longitudinal driving power source 16, and a lower longitudinal slide 21 is installed on the lower part thereof, the upper longitudinal slide 17 is installed with an upper heat sealing knife 20 through an upper bracket 18, and the lower longitudinal slide 21 is installed with a lower heat sealing knife 23 through a lower bracket 22. A cutter 19 is mounted on the upper bracket 18 and inside the upper heat sealing knife 20 (the inner wall of the upper heat sealing knife cooperates with the cutter and is suspended under the upper bracket through a spring), and the blade (tip) of the cutter 19 is above the upper heat sealing knife 20 (its lower heat sealing surface) (when not in operation).

[0014] The horizontal transverse driving power source 14, the transverse slide 15, the upper and lower longitudinal driving power sources 16, the upper longitudinal slide 17, the upper bracket 18, the cutting knife 19, the upper heat sealing knife 20, the lower longitudinal slide 21, the lower bracket 22, and the lower heat sealing knife 23 constitute a heat sealing cutting mechanism (a key component of the whole machine, located between the material feeding mechanism and the finished product discharging mechanism). In order to improve the efficiency of heat sealing and cutting to achieve high-speed production, the main machine archway 1 includes a main machine archway placed in the front position and the rear position. The heat sealing and cutting mechanism is composed of two sets (front and rear sets) and is respectively installed on the inner side of the main machine archway placed in the front position and the rear position. The two sets of heat sealing and cutting mechanisms are used alternately, achieving twice the output of the original similar equipment.

[0015] in:

[0016] 1. The spacer synchronous belt assembly 2 (PE engineering plastic material) of the material conveying mechanism is driven by the material conveying rotating power source 3 (material conveying disc servo motor) to feed the material into the bag former at the required linear speed according to the plate length;

[0017] Second, the traction roller 4 of the film traction mechanism is driven by the traction roller rotation power source 5 (a traction roller disc servo motor) to traction the film synchronously forward into the above-mentioned bag former (to form a pre-packaged bag with materials), and then sent to the film traction longitudinal sealing mechanism;

[0018] 3. The traction wheels 7 (two pieces) of the film traction longitudinal sealing mechanism are directly driven by the traction wheel rotation power source 6 (traction wheel disc servo motor) to synchronously pull the longitudinal seal of the pre-packaged bag into between the two longitudinal sealing knives to be heat-sealed, and the longitudinal sealing embossing wheels 9 (two pieces) are directly driven by the embossing wheel rotation power source 8 (embossing wheel disc servo motor) to synchronously heat-press the pattern at the longitudinal seal of the pre-packaged bag and deliver it to the feeding mechanism;

[0019] Fourth, the material feeding mechanism comprises an interconnected material feeding friction belt assembly 10 and a material feeding rotary power source 13 (a material feeding disc servo motor), which are in two sets, and are installed on the material feeding upper regulator 12 and the material feeding lower regulator 11 respectively. The material feeding lower regulator 11 (controlled by a hand wheel) and the material feeding upper regulator 12 (controlled by the material feeding upper regulating rotary power source, i.e., the material feeding upper regulating disc servo motor) are adjusted to a spacing suitable for clamping bag thickness, and the packaging bag clamping the inner material is driven by the material feeding rotary power source 13, and the pre-packaged bag is sent to the heat-sealing cutting mechanism at the required line speed;

[0020] 5. The upper and lower longitudinal driving power sources 16 of the heat-sealing and cutting mechanism drive the upper and lower longitudinal slides 17, 21 (i.e., double slides) and the upper and lower brackets 18, 22, upper and lower heat-sealing knives 20, 23, and cutting knife 19 mounted thereon to make vertical longitudinal separation and reciprocating motions through the left-handed and right-handed transmission screws on them. The transverse driving power source 14 and the transverse slide 15 drive the upper and lower longitudinal driving power sources 16 mounted thereon to make transverse (horizontal) reciprocating motions. The upper and lower heat-sealing knives and cutting knives, etc., are first closed and clamped by the upper and lower longitudinal driving power sources 16 and the above-mentioned transverse driving power source 14 to seal and cut the bag mouth of the packaging bag, then move forward horizontally (all during heat sealing), then separate and return while moving up and down, and then close again. The cyclic motion successively moves the finished products horizontally forward to the finished product discharging mechanism. As described above, the present invention is designed with two sets of heat-sealing and cutting mechanisms, which are used alternately with each other, achieving twice the output of the original similar equipment;

[0021] 6. The finished product discharging mechanism includes an interconnected discharging conveyor belt assembly 24, a discharging rotating power source 27 (a discharging disc servo motor), and corresponding discharging lower regulators 26 and discharging horizontal regulators 27. The discharging conveyor belt assembly 24 is adjusted to the optimal position of up and down and left and right through the discharging lower regulator 26 (controlled by a hand wheel) and the discharging horizontal regulator 27 (controlled by the discharging lateral adjustment driving power source, i.e., the discharging lateral adjustment linear servo motor), and is driven by the discharging rotating power source 25 (a discharging disc servo motor) to convey the finished packaging bags to the desired destination at a speed slightly faster than the line speed of the whole machine.

[0022] The installation, connection and operation functions of the parts related to each process are as follows:

[0023] Process 1: Material conveying mechanism: Figure 1 , Figure 2 As shown, the material conveying rotary power source 3 is installed in the middle of the material running platform, and the synchronous wheel is directly installed on the shaft head of the material conveying rotary power source 3. The attached spacer synchronous belt assembly 2 (the spacing between the spacers is based on the longest product of the user. When the bag is shorter than the existing spacing, the material conveying rotary power source 3 can be adjusted to speed up the linear speed of the attached spacer synchronous belt assembly 2 to catch up with the gap between the long and short bags without replacing the synchronous belt assembly with different spacer spacing) is closely connected to this synchronous wheel and installed in the middle of the left side of the plane where the whole machine material runs. The material conveying rotary power source 3 is directly driven at the required linear speed (a batch of mechanical parts for long-distance transfer transmission are omitted), so that the spacers pushing the material upwards successively send the material into the bag former at the required linear speed of the plate length. The attached spacer synchronous belt assembly 2 (PE engineering plastic material) of the material conveying mechanism is driven by the material conveying rotary power source 3 (a material conveying disc servo motor) to send the material into the bag former at the required linear speed of its plate length;

[0024] Process 2: Film pulling mechanism: Figure 1 , Figure 3 As shown, the traction roller rotation power source 5 is installed on the inner wall above the main machine arch 1 (large), and the traction roller 4 with a mesh pattern on the outer circumference is directly mounted on the inner hole of the traction roller rotation power source 5. The traction roller 4 and the pressure roller are directly driven by the traction roller rotation power source 5 (easier to be controlled by the program, which is conducive to the coordinated operation of various parts) to pull the film into the bag former, receive the material entering the bag former in the previous process (to form a prefabricated bag, i.e., a pre-packaged bag) and send it to the film traction longitudinal sealing mechanism together;

[0025] Process 3: Film pulling and longitudinal sealing mechanism: Figures 1 to 3 As shown, the inner hole of the traction wheel rotation power source 6 is directly mounted on the lower end of the bearing shaft of the traction wheel 7, and the coaxial direct-driven traction wheel 7 (two pieces) synchronously pulls the longitudinal seal of the pre-packaged bag into between the two longitudinal sealing knives for heat sealing. The inner hole of the embossing rotation power source 8 is also directly mounted on the lower end of the bearing shaft of the longitudinal sealing embossing wheel 9, and the coaxial direct-driven longitudinal sealing embossing wheel 9 (two pieces) synchronously heat-presses the pattern at the longitudinal seal of the pre-packaged bag, and delivers the packaging bag (prefabricated bag) with the material into the material introduction mechanism (eliminating a number of complex transmission parts, effectively simplifying the structure);

[0026] Process 4: Material feeding mechanism: Figure 1 , Figure 2 As shown, the upper and lower material guide regulators 12 and 11 are installed on the inner wall of the main machine arch 1, and the upper and lower material guide friction belt assemblies 10 (one set each for the upper and lower positions) are respectively installed on the upper and lower material guide regulators 12 and 11. The spacing between the upper and lower material guide friction belt assemblies 10 is adjusted to the best state suitable for clamping by the automatic control of the upper material guide adjustment rotating power source of the upper material guide regulator 12 (which can be raised and lowered by 70mm) and the manual operation of the hand wheel of the lower material guide regulator 11 (which can be fine-tuned by 10mm) according to the requirements of bag thickness changes, and then the material guide friction belt assembly is driven by the material guide rotating power source 13 to clamp and pull the packaging bag with the material inside to move forward in the required direction and linear speed level and send it to the heat sealing cutting mechanism (which can meet the traction packaging of materials with different bag thicknesses from 5mm to 80mm). It has a simple structure and reliable operation.

[0027] Process 5: When the heat sealing and cutting mechanism is a set: Figures 1 to 4As shown, the transverse driving power source 14 is installed on the inner side of the main machine arch 1, which is equipped with a transverse slide 15, and the upper and lower longitudinal driving power sources 16 are installed on the transverse slide 15. The upper and lower longitudinal driving power sources are equipped with upper and lower longitudinal slides 17, 21 and upper and lower brackets 18, 22 and upper and lower heat sealing knives 20, 23, cutting knife 19, etc. The operation mode is: the transverse driving power source 14 controls the transverse slide 15 to drive the upper and lower longitudinal driving power source 16 to make transverse (horizontal) reciprocating motion; the upper and lower longitudinal driving power source 16 controls the upper and lower longitudinal slides 17, 21 (double slide mode) through the left-handed and right-handed transmission screws on them to drive the upper and lower heat sealing knives 20, 23 and the cutting knife 19 installed thereon to make corresponding upper and lower longitudinal reciprocating motions. The operation steps are as follows: when the machine is turned on, the upper and lower heat-sealing knives 20, 23, and the cutting knife 19 are controlled by the horizontal driving power source 14 and the upper and lower longitudinal driving power source 16. First, the bag mouth is closed and clamped, and the bag is sealed and cut while moving horizontally with the same line speed as the whole machine for a long stroke (one bag is sealed and cut in each stroke. In each stroke of the present invention, the upper and lower heat-sealing knives 20, 23 clamp the packaging film and heat-seal the bag mouth. The sealing time is more than five times that of the traditional known technology, which completely solves the problem of poor sealing of the bag mouth of the original design). When the machine reaches the end point, the finished product is sent to the finished product discharging mechanism and then returns. The return journey has the following four operation modes (such as Figure 4 Method 1: The upper and lower heat sealing knives and the cutting knives are separated in an upper and lower parabola shape while returning backwards, and when they return halfway, they change to continue to return backwards while closing in a lower and upper parabola shape, and then clamp the subsequent bag mouth for sealing, cutting and moving forward to the end point, and repeat the cycle to form two upper and lower parabolic motion trajectories A; Method 2: The upper and lower heat sealing knives and the cutting knives are separated in an upper and lower oblique line shape while returning backwards, and when they return a certain distance, they change to return horizontally, and when they return a certain distance, they change to continue to return backwards while closing in a lower and upper oblique line shape, and then clamp the subsequent bag mouth for sealing, cutting and moving forward to the end point, and repeat the cycle The loop makes two trapezoidal motion trajectories B in the upper and lower shapes; Mode 3: The upper and lower heat sealing knives and cutting knives are separated in the shape of upper and lower oblique lines while returning backwards, and when they return halfway, they change to continue to return backwards while closing in the shape of lower and upper oblique lines, then clamp the bag mouth for sealing, cutting and moving forward to the end point, and repeat the cycle to make two triangular motion trajectories C in the upper and lower shapes; Mode 4: The upper and lower heat sealing knives and cutting knives are first separated by the required distance, and then immediately adjusted to a uniform horizontal return, and then immediately closed and clamped the subsequent bag mouth for sealing, cutting and moving forward to the end point, and repeat the cycle to make two rectangular motion trajectories D in the upper and lower shapes. The four operating modes can be selected according to the shape of the packaged object, and the cycle is repeated, and the bag mouth is clamped, sealed, and cut successively, and the finished product is sent horizontally to the finished product discharge mechanism to achieve the purpose of the present invention.

[0028] When there are two sets of heat sealing and cutting mechanisms: Figure 2 , Figure 3 As shown, in order to improve work efficiency and realize high-speed production, the present invention designs two sets of heat sealing and cutting mechanisms (front and rear sets in the left and right directions), and each set of heat sealing and cutting mechanisms is installed on the inner side of the two main machine arches placed in the front and rear positions. When the upper and lower heat sealing knives and cutting knives of one set of heat sealing and cutting mechanisms are driven up and down respectively by the upper and lower longitudinal driving linear servo motors to control the upper and lower longitudinal slides (i.e., the double slide mode), the upper and lower heat sealing knives and cutting knives close the heat sealing and the cutting knives cut the bag opening of the packaging bag while being driven to move horizontally to the right at a uniform speed by the transverse driving linear servo motor to control the transverse slide; at the same time, the upper and lower heat sealing knives and cutting knives of another set of heat sealing and cutting mechanisms are driven to separate while being driven by the upper and lower longitudinal driving linear servo motors to control the upper and lower longitudinal slides while being driven to return to the left by the transverse driving linear servo motor to control the transverse slide. When the return is halfway (the distance separated by the upper and lower heat sealing knives of this set is just passed by the upper and lower heat sealing knives and upper and lower brackets of another set of heat sealing and cutting mechanisms in the closed state moving horizontally to the right), then continue to return to the right end of the material guiding mechanism while closing, and then similarly clamp and seal the subsequent packaging bag with the material inside and move horizontally to the right at a uniform speed. The two sets of heat sealing and cutting mechanisms can be selected according to the conditions of the packaged materials. Figure 4 The four operation modes shown are as follows (the previous operation is taken as the starting point). Mode 1: The upper and lower heat sealing knives and cutting knives are first closed to clamp the bag mouth to seal and cut, and then move forward horizontally. In the return process, they are separated in an upper and lower parabolic shape (the first half) and closed in a lower and upper parabolic shape (the second half), and then clamp the subsequent bag mouth to move forward horizontally in the upper and lower parabolic motion trajectories A; Mode 2: The upper and lower heat sealing knives and cutting knives are first closed to clamp the bag mouth to seal and cut, and then move forward horizontally. In the return process, they are separated in an upper and lower oblique shape (about 1 / 3 of the return), followed by a horizontal return (about 1 / 3 of the return), and then closed in a lower and upper oblique shape (about 1 / 3 of the return), and then in the return process. The upper and lower trapezoidal motion trajectories B of the subsequent bag opening are clamped and moved forward horizontally; the third mode: the upper and lower heat sealing knives and cutting knives are first closed to clamp the bag opening to seal, cut and move forward horizontally, and then return to separate in upper and lower oblique lines and close in lower and upper oblique lines, and then clamp the subsequent bag opening to move forward horizontally in upper and lower triangular motion trajectories C; the fourth mode: the upper and lower heat sealing knives and cutting knives are first closed to clamp the bag opening to seal, cut and move forward horizontally, and then return to separate instantly, then return horizontally, and then close instantly, and then clamp the subsequent bag opening to move forward horizontally in upper and lower rectangular motion trajectories D. The four operation modes can be selected according to the shape of the packaged object, and the best mode can be used to perform continuous alternating and repetitive cyclic motions, and each of them successively sends the sealed and cut products to the finished product discharge mechanism, so as to achieve the production efficiency of the present invention twice that of the original equipment.

[0029] The relationship between the upper and lower heat sealing knives and the cutting knives in the heat sealing and cutting mechanism: Figure 1 , Figure 3 , Figure 4 As shown, the upper and lower brackets 18, 22 and the upper and lower heat sealing knives 20, 23 and the cutter 19 are respectively mounted on the upper and lower longitudinal slides 17, 21 of the upper and lower longitudinal driving power sources 16. The upper heat sealing knife 20 is pressed down by a spring and hung below the upper bracket 18 (about 5 mm), and the cutter 19 passes through the inner part (middle part) of the upper heat sealing knife 20 and is fixedly mounted on the upper bracket 18. When the upper heat sealing knife 20 moves downward to contact the lower heat sealing surface of the upper heat sealing knife 20 to seal the bag opening, the cutter 19 continues to move downward to the lower heat sealing surface of the upper heat sealing knife and begins to cut into the bag (film). When the upper and lower heat sealing knives 20, 23 are closed and compacted, the cutter 19 naturally cuts in about 3 mm, achieving the effect of stably cutting the front and rear packaging bags, reducing the transmission parts and power sources required for the original cutter.

[0030] Process 6: Finished product discharging mechanism: Figures 1 to 3 As shown, the finished product discharging mechanism includes an interconnected discharging conveyor belt assembly 24, a discharging rotary power source 27 (a discharging disc servo motor), and a discharging lower regulator 26 and a discharging horizontal regulator 27. The discharging horizontal regulator 27 (controlled by the discharging lateral adjustment driving power source, i.e., the discharging lateral adjustment linear servo motor) is installed on the inner wall of the main machine arch 1, the discharging lower regulator 26 (with a hand wheel) is installed on the discharging horizontal regulator 27, and the discharging conveyor belt assembly 24 is installed on the discharging lower regulator 26. The hand wheel of the discharging lower regulator 26 can adjust the height of the upper plane of the discharging conveyor belt assembly 24, and the discharging lateral adjustment driving power source of the discharging horizontal regulator 27 can be adjusted by 135mm accordingly with the change of the bag length stroke, solving the packaging problem of different bag lengths of 60mm-195mm. During operation, the hand wheel of the discharge lower regulator 26 adjusts the upper plane of the discharge conveyor belt assembly 24 to a position slightly lower than the lower bottom of the finished product, and the discharge lateral adjustment driving power source of the discharge horizontal regulator 27 adjusts the discharge conveyor belt assembly to the optimal left and right positions, and then is directly driven by the discharge rotation power source 25 to move forward at a speed slightly faster than the line speed of the whole machine, and the cut finished products are smoothly delivered to the subsequent process equipment or containers.

[0031] The present invention relates to a high-speed intelligent pillow packaging machine. In the macroscopic view, each part adopts a plurality of servo motors (a total of thirteen disc or linear types) and PE engineering plastic synchronous conveyor belt components and other modern advanced transmission devices. The direct drive method of each part eliminates a batch of traditional mechanical parts such as sprockets, chains, tension wheels, gears, eccentric wheels, etc. for long-distance transfer transmission, effectively simplifies the transmission mechanism of the equipment, reduces the working noise, and improves the operating speed and accuracy. The material conveying rotary power source 3 (material conveying disc servo motor), the traction roller rotary power source 5 (traction roller disc servo motor), the traction wheel rotary power source 6 (traction wheel disc servo motor) and the embossing wheel rotary power source 8 (embossing wheel disc servo motor), the material introduction upper adjustment rotary power source (material introduction upper adjustment disc servo motor), the two material introduction rotary power sources 13 (material introduction disc servo motors), the two lateral drive power sources 14 (lateral drive linear servo motors) and the two upper and lower longitudinal drive power sources 16 (upper and lower longitudinal drive linear servo motors) of the heat sealing and cutting mechanism, the material discharging rotary power source 25 (material discharging disc servo motor), the material discharging lateral adjustment drive power source (material discharging lateral adjustment linear servo motor) etc. (a total of thirteen disc or linear servo motors) are respectively electrically connected to the microcomputer control mechanism 28 and are uniformly regulated by it, and are controlled by the programmable control program of the microcomputer control mechanism, so that the running time, rotation speed, stroke and linear speed of each of the above-mentioned mechanisms can be perfectly and arbitrarily set and coordinated, and can meet the diversified product packaging needs of different lengths, widths and thicknesses.
