Description

Technical Field

[0001] The present application relates to the technical field of packaging bag production equipment, and in particular to a multifunctional conveying system for packaging bag production. Background Art

[0002] At present, food packaging bags refer to bags used to package various supplies, which make it easy to transport and store goods during production and circulation. They are widely used in daily life and industrial production. Food packaging bags are divided into plastic packaging bags, paper packaging bags, vacuum packaging bags, etc. according to the material; according to the shape of the packaging bags, they can be divided into M-shaped folding packaging bags, flat packaging bags, and single-side sealed packaging bags.

[0003] Different packaging bags have different corresponding production processes. For example, an M-shaped folded edge packaging bag is often a single-layer raw material film that is unrolled and then folded from both ends to the middle by a folding component. The overlapping parts of the folded parts are then sealed by a sealing device. The sealed packaging bag is then folded and flattened by a folding device to form an M-shaped crease on both sides of the packaging bag. Finally, the packaging bag is sealed and cut by a sealing device and a shearing component to form an M-shaped folded edge packaging bag.

[0004] Ordinary flat-mouth packaging bags require first unrolling the single-layer raw material film, cutting the single-layer raw material film in the middle and aligning it, then using a sealing device to seal the two sides of the aligned packaging bag, and finally using a sealing device and a cutting device to seal and cut the other side of the packaging bag to form a flat-mouth packaging bag.

[0005] The production processes for different packaging bags are different, and the required production equipment is also inconsistent. The production of the entire packaging bag involves an entire production line. Different production lines need to be set up for production in response to different production needs. The adaptability of the entire production line is relatively single, so it is not easy to meet production needs when the production demand is large. Summary of the invention

[0006] In order to improve the adaptability of the production line, facilitate the production line to produce different types of packaging bags, and adjust the production line according to different production needs to meet production needs, the present application provides a multifunctional conveying system for packaging bag production.

[0007] The present application provides a multifunctional conveying system for packaging bag production using the following technical solutions:

[0008] A multifunctional conveying system for packaging bag production, comprising a conveyor belt and an unwinding device arranged at one end of the conveyor belt, a cutting device is arranged at the other end of the conveyor belt, a mounting frame is arranged between the unwinding device and the cutting device, a heat sealing device is arranged on the mounting frame, a folding assembly, a shearing assembly and an adjusting assembly are arranged at one end of the mounting frame close to the unwinding device, the folding assembly and the shearing assembly are movably corresponding to the raw material, and a folding assembly is arranged at one end of the mounting frame close to the cutting device; the folding assembly comprises a clamping rod slidably arranged on the mounting frame and a movable part for slidingly adjusting the clamping rod, the clamping rod is provided with two groups, and the two groups of the clamping rods are arranged relatively, the clamping rods clamp and turn the sides of the packaging bag, and the movable part is used to adjust the spacing between the two groups of clamping rods; the shearing assembly comprises a shearing blade slidably arranged on the mounting frame, and the shearing blade is movably corresponding to the center of the raw material belt; the adjusting assembly is arranged on the mounting frame to make the folding assembly and the shearing assembly correspond to the raw material belt.

[0009] By adopting the above technical solution, when it is necessary to produce folded edge bags, the two sides of the raw material belt need to be pressed and folded. The technician adjusts the components to make the folding components correspond to the raw material belt. At this time, the two sets of pressing rods press and turn the two sides of the raw material belt respectively, so as to facilitate the subsequent folding of the raw material belt. At the same time, the spacing between the two sets of pressing rods is adjusted by the provided movable parts, so as to realize the folding operation of folded edge bags of different specifications, thereby improving the adaptability of the conveying system.

[0010] When it is necessary to produce flat bags, the technician adjusts the components to make the shearing components correspond to the raw material belt. At this time, the shearing blade corresponds to the center of the raw material belt. The raw material belt is cut during the conveying process, so that the two cut raw material belts can be heat-sealed to form flat bags.

[0011] When producing different types of packaging bags (folded edge bags and flat bags), technicians adjust the adjustment components according to production needs, so that either the folding component or the shearing component corresponds to the raw material belt, thereby realizing the production of folded edge bags and flat bags, improving the adaptability of the entire conveying system, reducing efficiency problems caused by the mismatch between the conveying system and production needs, improving production efficiency, and at the same time reducing cost problems caused by increasing the conveying system lines due to production needs, saving costs, and improving production efficiency.

[0012] Optionally, the adjustment assembly includes a mounting block rotatably disposed on the mounting frame and a positioning member for positioning the rotational position of the mounting block, the rotational axis of the mounting block is perpendicular to the length direction of the conveyor belt, and the clamping rod and the shearing blade are both disposed on the mounting block.

[0013] By adopting the above technical solution, the clamping rod and the shearing blade are both arranged on the mounting block. When different types of packaging bags need to be produced, the technician only needs to rotate the mounting block to make the clamping rod / shearing blade correspond to the raw material belt to achieve folding or shearing operations. The adjustment operation is simple. The position of the shearing blade and the clamping rod can be fixed by corresponding the position of the mounting block with the positioning parts, thereby achieving stable folding and stable shearing.

[0014] Optionally, the positioning member includes a positioning block slidably arranged on the mounting frame, the mounting block is provided with a positioning groove, the positioning block is plug-fitted into the positioning groove, and the outer peripheral wall of the positioning block is tightly abutted against the inner side wall of the positioning groove, the positioning block is polygonal in shape, and the positioning block is snap-fitted into the positioning groove.

[0015] By adopting the above technical solution, when adjusting the position of the mounting block according to different production needs, the technician first pulls out the positioning block to separate the positioning block from the positioning groove, and then rotates the mounting block so that the abutment rod / shear blade corresponds to the raw material belt. The technician then inserts the positioning block, and the positioning block is engaged with the positioning groove, thereby fixing the position of the abutment rod and the shear blade, thereby achieving stable folding on both sides of the folding bag and stable shearing of the raw material belt by the shear blade.

[0016] Optionally, the folding assembly also includes a clamping plate arranged on the positioning block, the clamping plate is movably arranged to fit the surface of the raw material belt, and the clamping plate is located on the side of the clamping rod away from the shearing blade, two groups of the clamping rods are symmetrically arranged on both sides of the clamping plate, and the clamping plate is consistent with the width of the finished packaging bag.

[0017] In the process of folding, it is easy to produce excessive or insufficient folding, which affects the forming quality of the folded bag. The clamping plate is set on the side of the clamping rod close to the input end of the raw material belt. Before folding, the clamping plate is fitted with the raw material belt. After the clamping plate and the raw material belt are tightly pressed, the side of the raw material belt is pressed and folded by the clamping rod, thereby reducing the occurrence of excessive or insufficient folding and improving the quality of the finished packaging bag.

[0018] The abutment plate is set to be consistent with the width of the finished product packaging bag, thereby improving the size and precision of the finished product.

[0019] Optionally, a sliding groove is provided on the mounting frame, and the sliding member includes a sliding block arranged on the side of the clamping rod away from the conveyor belt, the sliding block is slidably arranged in the sliding groove, a rotating screw is rotatably arranged in the sliding groove, and the rotating screw is provided with an external thread with the same pitch and opposite thread, and the sliding blocks corresponding to the two clamping rods are symmetrically threaded at both ends of the rotating screw.

[0020] By adopting the above technical scheme, when producing folding bags of different sizes, the abutment plate needs to be replaced and the abutment rod needs to be adjusted to achieve folding of different widths. When adjusting the abutment rod, the technician only needs to rotate the rotating screw to drive the sliding block to slide along the rotating screw. Under the limitation of the sliding groove, since the rotating screw is provided with an external thread with opposite thread pitch and the same thread pitch, when the rotating screw rotates, the sliding blocks corresponding to the two abutment rods move in opposite or relative directions, thereby adjusting the distance between the two abutment rods, thereby realizing the folding operation of folding bags of different widths, further improving the adaptability of the device; and realizing synchronous adjustment of the two abutment rods through a rotating screw, realizing that the two abutment rods are always centered, saving the power problem and error problem caused by adjusting the two abutment rods separately, thereby improving the accuracy of folding bags during production.

[0021] Optionally, the folding assembly includes an adsorption member arranged on the mounting frame and a folding roller rotatably arranged on the mounting frame, the adsorption member includes a first adsorption nozzle and a second adsorption nozzle symmetrically arranged along the upper and lower sides of the raw material belt, and the first adsorption nozzle and the second adsorption nozzle are symmetrically arranged along the surface of the conveyor belt, the folding roller is in contact with the middle part of the side of the raw material belt, and the mounting frame is also provided with a linkage member for synchronously adjusting the folding assembly and the folding assembly.

[0022] By adopting the above technical scheme, after the folding component folds the raw material belt, the folded raw material belt has formed a double-layer form. In order to increase the packaging capacity of the folded bag, it is still necessary to fold the raw material belt that has formed a double-layer form so that the side of the raw material belt is in an "M" shape. When it is conveyed to the side close to the cutting device, the raw material belt is adsorbed by the first adsorption nozzle and the second adsorption nozzle, so that the side of the raw material belt is easy to fold inward, and then the side of the raw material belt is folded inward under the pressure of the folding roller. Because the first adsorption nozzle and the second adsorption nozzle are symmetrical along the surface of the conveyor belt, the middle part of the "raised" side of the raw material belt is aligned with the folding roller, so that the side of the raw material belt is folded.

[0023] The linkage parts arranged at the same time can synchronously adjust the folding assembly and the folding assembly. When it is necessary to produce folded bags, the folding assembly and the folding assembly can be simultaneously rotated to the working position through the linkage parts. When it is necessary to produce flat bags, the linkage parts can make the folding assembly and the folding assembly rotate away from the working position, thereby realizing the switching of the device into different states according to production needs.

[0024] Optionally, the linkage part includes a sliding rack slidably arranged in the mounting frame, a sliding gear is provided at the rotating shaft of the mounting block, the sliding gear is meshed with the sliding rack, a driven gear is provided in the mounting frame, the driven gear is also meshed with the sliding rack, the folding roller is rotatably connected with a connecting rod between the mounting frames, the rotating shaft of the connecting rod is provided with a driving gear, the driven gear is transmission-connected with the driving gear, and a limiting member for positioning the position of the folding roller is also provided on the mounting frame; when the mounting block is rotated to make the folding assembly correspond to the raw material belt, the folding roller rotates to correspond to the middle part of the side edge of the raw material belt.

[0025] By adopting the above technical solution, when it is necessary to produce hemmed bags, the mounting block needs to be rotated to make the abutment rod and the abutment plate correspond to the raw material belt. When the mounting block rotates, it drives the sliding gear to rotate, and the sliding gear drives the sliding rack to slide, and the sliding rack drives the driven gear to rotate, thereby driving the driving gear to rotate, so as to realize the synchronous rotation of the two connecting rods and the synchronous adjustment of the folding assembly and the side assembly. That is, when it is necessary to produce hemmed bags, the hemming assembly and the folding assembly can be synchronously moved to the working position by rotating the mounting block, and when it is necessary to produce flat bags, the hemming assembly and the folding assembly can be synchronously moved to a position away from the working state by rotating the mounting block.

[0026] At the same time, the position of the connecting rod is limited by the set limit piece, so that the position of the mounting block is fixed by the set positioning block, and the set limit piece limits the position of the connecting rod, further improving the stability of the folding bag production.

[0027] Optionally, the limiting member includes a limiting block elastically arranged on the mounting frame, and the limiting block is movably pressed against two side walls of the connecting rod along the rotation direction of the connecting rod.

[0028] By adopting the above technical solution, when the installation block rotates until the hemming roller is in the working state, the limit block presses against the side of the connecting rod under the action of the elastic restoring force, so that the connecting rod is not easy to rotate, thereby achieving stable hemming;

[0029] When the mounting block rotates until the folding roller is away from the working state, the limit block presses the opposite sides of the connecting rod under the action of the elastic restoring force, making it difficult for the connecting rod to rotate close to the working state, thereby reducing the interference of the folding roller on the flat bag production process.

[0030] Optionally, an electrostatic roller is rotatably connected to the clamping plate, the electrostatic roller is in contact with the surface of the raw material belt, and the electrostatic roller is hollow. A steam component for passing hot steam into the electrostatic roller is provided on the mounting frame, and a plurality of electrostatic holes are densely distributed on the outer peripheral wall of the electrostatic roller.

[0031] By adopting the above technical solution, when producing folding bags, the raw material belt needs to be adsorbed to the bulge through the first adsorption nozzle and the second adsorption nozzle, so as to facilitate M-shaped folding. During the conveying process, static electricity is likely to exist between the interlayers of the raw material belt, which causes the first adsorption nozzle and the second adsorption nozzle to easily generate side wrinkles when adsorbing the raw material belt. Therefore, when the electrostatic roller arranged on the pressing plate is conveyed and rotated in conjunction with the raw material belt, the steam part conveys hot steam to the electrostatic roller, and the hot steam overflows from the electrostatic hole, thereby removing the static electricity generated on the inner side of the raw material belt, facilitating the subsequent adsorption of the raw material belt by the first adsorption nozzle and the second adsorption nozzle, and facilitating the subsequent folding operation.

[0032] At the same time, when producing folded bags, it is necessary to overcome the static electricity between the inner walls of the raw material belt, and when producing flat bags, it is necessary to use the static electricity between the inner walls of the raw material belt to keep the upper and lower sides of the raw material belt aligned. Therefore, the electrostatic roller is set on the clamping plate. When producing folded bags, while the electrostatic roller clamps the raw material belt, the electrostatic roller automatically removes the static electricity on the inner wall of the raw material belt, which is convenient for subsequent folding operations; when producing flat bags, it is necessary to rotate the mounting block to store and fold the clamping plate, and the electrostatic roller is stored and folded accordingly, so as to facilitate the use of static electricity when making flat bags, and then facilitate the production of flat bags.

[0033] Optionally, a pleating roller is rotatably arranged on the mounting frame, and the pleating roller is arranged between the clamping rod and the folding roller. The pleating roller is arranged to fit the surface of the raw material strip, and there are two groups of pleating rollers, and the two groups of pleating rollers are relatively symmetrically arranged. An operating member for synchronously adjusting the two groups of pleating rollers is provided on the mounting frame.

[0034] By adopting the above technical solution, no matter whether it is producing folded bags or flat bags, it is necessary to perform pleating operation on the folded parts, so as to achieve stable quality of the finished packaging bags; the set pleating roller pleats the folded edges, so as to achieve stable folding operation and reduce subsequent insufficient folding caused by insufficient folding. At the same time, when producing flat bags, the set pleating roller flattens the cut raw material strips sufficiently to keep the upper and lower sides of the raw material strips stably fitted.

[0035] The pleating roller is arranged between the pressing rod and the folding roller, and the pleating roller is not easily offset due to the rotation of the mounting block, thereby achieving stability in the production process of the folding bag and the flat bag.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. By setting the shearing assembly, folding assembly and adjusting assembly, the positions of the folding assembly and the shearing assembly are adjusted by the adjusting assembly, so that when producing gusseted bags, the technicians can rotate the folding assembly to the corresponding position by adjusting the assembly to realize the production of gusseted bags. When producing flat bags, the shearing assembly is adjusted to correspond to the raw material belt by adjusting the assembly to realize the production of flat bags;

[0038] 2. By rotating the mounting block and the abutting rod and shear blade arranged on the mounting block, when the production requirements are different, the technicians can rotate the mounting block to make the abutting rod correspond to the raw material belt or the shear blade correspond to the raw material belt, so as to meet different production requirements;

[0039] 3. Through the folding components and linkage parts, when the technicians rotate the mounting blocks to meet different production needs, the linkage parts can automatically realize the folding of the raw material belt after it enters the conveyor belt and the M-shaped folding operation on the side of the raw material bag after folding. There is no need to set up an additional power source, and the adjustment is simple, and production can be automatically realized. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-5 This application is described in further detail.

[0047] The present application embodiment discloses a multifunctional conveying system for packaging bag production. Figure 2 and Figure 3 A multifunctional conveying system for packaging bag production includes an unwinding device 11, a conveyor belt 1 and a cutting device 12 arranged in sequence. The unwinding device 11 is used to unwind the raw material belt, the conveyor belt 1 is used to convey the unwinded raw material belt, and the cutting device 12 is used to cut and process the processed raw material belt. A mounting frame 13 is provided between the unwinding device 11 and the cutting device 12, and a heat sealing device 14 is provided on the mounting frame 13. A folding assembly 2, a shearing assembly 3 and an adjusting assembly 4 are provided at one end of the mounting frame 13 close to the unwinding device 11. The folding assembly 2 and the shearing assembly 3 correspond to the raw material. A folding assembly 5 is provided at one end of the mounting frame 13 close to the cutting device 12. The folding assembly 2 includes a clamping rod 22 slidably provided on the mounting frame 13 and a movable part 23 for slidingly adjusting the clamping rod 22. The clamping rod 22 is provided with two groups, and the two groups of clamping rods 22 are arranged oppositely. The clamping rod 22 clamps and turns the side of the packaging bag, and the movable part 23 is used to adjust the distance between the two groups of clamping rods 22. The shearing assembly 3 includes a shearing blade 31 rotatably provided on the mounting frame 13, and the shearing blade 31 corresponds to the center of the raw material strip. The adjusting assembly 4 is provided on the mounting frame 13 to make the folding assembly 2 and the shearing assembly 3 correspond to the raw material strip.

[0048] When it is necessary to produce folded edge bags, it is necessary to press and fold the two sides of the raw material belt. The technician adjusts the component 4 to make the folding component 2 correspond to the raw material belt. At this time, the two sets of pressing rods 22 press and turn the two sides of the raw material belt respectively, so as to facilitate the subsequent folding of the raw material belt. At the same time, the spacing between the two sets of pressing rods 22 is adjusted by the movable parts 23, so as to realize the folding operation of folded edge bags of different specifications, thereby improving the adaptability of the conveying system.

[0049] When it is necessary to produce a flat bag, the technician adjusts the assembly 4 so that the shearing assembly 3 corresponds to the raw material tape. At this time, the shearing blade 31 corresponds to the center of the raw material tape, and the raw material tape is cut during the conveying process of the raw material tape, so that the two cut raw material tapes can be heat-sealed to form a flat bag later.

[0050] When producing different types of packaging bags (folded edge bags and flat bags), technicians adjust the adjustment component 4 according to production needs, so that either the folding component 2 or the shearing component 3 corresponds to the raw material belt, thereby realizing the production of folded edge bags and flat bags, improving the adaptability of the entire conveying system, reducing efficiency problems caused by the mismatch between the conveying system and production needs, improving production efficiency, and at the same time reducing cost problems caused by increasing the conveying system lines due to production needs, saving costs, and improving production efficiency.

[0051] The adjustment component 4 includes a mounting block 41 rotatably arranged on the mounting frame 13 and a positioning member 42 for positioning the rotational position of the mounting block 41. The rotational axis of the mounting block 41 is perpendicular to the length direction of the conveyor belt 1. The clamping rod 22 and the shearing blade 31 are both arranged on the mounting block 41. The clamping rod 22 and the shearing blade 31 are both arranged on the mounting block 41. When it is necessary to produce packaging bags of different varieties, the technician only needs to rotate the mounting block 41 to make the clamping rod 22 / the shearing blade 31 correspond to the raw material belt to realize the folding or shearing operation. The adjustment operation is simple. By setting the positioning member 42 to correspond to the position of the mounting block 41, the position of the shearing blade 31 and the clamping rod 22 can be fixed, thereby realizing stable folding and stable shearing.

[0052] The positioning member 42 includes a positioning block 421 which is slidably arranged on the mounting frame 13, and a positioning groove 422 is provided on the mounting block 41. The positioning block 421 is plugged and matched with the positioning groove 422, and the outer peripheral wall of the positioning block 421 is tightly abutted against the inner side wall of the positioning groove 422. The positioning block 421 is polygonal in shape, and the positioning block 421 is snap-fitted and matched with the positioning groove 422; when the position of the mounting block 41 is adjusted according to different production needs, the technician first pulls out the positioning block 421 to separate the positioning block 421 from the positioning groove 422, and then rotates the mounting block 41 to make the abutment rod / shearing blade 31 correspond to the raw material belt at this time, and then the technician inserts the positioning block 421, and the positioning block 421 is snap-fitted with the positioning groove 422 at this time, thereby achieving the fixation of the position of the abutment rod and the shearing blade 31, thereby achieving stable folding of the two sides of the folding bag and stable shearing of the raw material belt by the shearing blade 31.

[0053] The folding assembly 2 also includes a clamping plate 24 arranged on the positioning block 421. The clamping plate 24 is movably arranged to fit the surface of the raw material belt, and the clamping plate 24 is located on the side of the clamping rod 22 away from the shear blade 31. Two groups of clamping rods 22 are symmetrically arranged on both sides of the clamping plate 24, and the width of the clamping plate 24 is consistent with that of the finished packaging bag. In the process of folding, excessive or insufficient folding is prone to occur, which affects the molding quality of the folded bag. The clamping plate 24 is arranged on the side of the clamping rod 22 close to the input end of the raw material belt, and is fitted with the raw material belt through the clamping plate 24 before folding. After the clamping plate 24 and the raw material belt are pressed tightly, the side edge of the raw material belt is pressed and folded by the clamping rod 22, thereby reducing the occurrence of excessive or insufficient folding and improving the finished product quality of the finished packaging bag.

[0054] The mounting frame 13 is provided with a sliding groove 231, and the sliding member includes a sliding block 232 arranged on the side of the clamping rod 22 away from the conveyor belt. The sliding block 232 is slidably arranged in the sliding groove 231, and a rotating screw rod 233 is rotatably arranged in the sliding groove 231. The rotating screw rod 233 is provided with an external thread with the same pitch and opposite threads, and the sliding blocks 232 corresponding to the two clamping rods 22 are symmetrically threaded at both ends of the rotating screw rod 233; at the same time, when producing hemming bags of different sizes, the abutment plate needs to be replaced, and the abutment rod needs to be adjusted to achieve hemming of different widths. When adjusting the abutment rod, the technician only needs to rotate the rotating screw rod 233 to rotate the screw rod 23 The sliding block 232 is driven to slide along the rotating screw 233. Under the limit of the sliding groove 231, since the rotating screw 233 is provided with an external thread with opposite threads and the same pitch, when the rotating screw 233 rotates, the sliding blocks 232 corresponding to the two abutting rods 22 move in opposite or relative directions, so as to adjust the spacing between the two abutting rods, thereby realizing the folding operation of hemming bags of different widths, further improving the adaptability of the device; and the synchronous adjustment between the two abutting rods is realized by a rotating screw 233, so that the two abutting rods are always aligned, saving the power problem and error problem caused by adjusting the two abutting rods separately, thereby improving the precision of the hemming bag production.

[0055] Reference Figure 3 and Figure 4 The folding assembly 5 includes an adsorption member 51 arranged on the mounting frame 13 and a folding roller 52 rotatably arranged on the mounting frame 13. The adsorption member 51 includes a first adsorption nozzle 511 and a second adsorption nozzle 512 symmetrically arranged along the upper and lower sides of the raw material belt, and the first adsorption nozzle 511 and the second adsorption nozzle 512 are symmetrically arranged along the surface of the conveyor belt 1. The folding roller 52 is in contact with the middle part of the side of the raw material belt, and the mounting frame 13 is also provided with a linkage member 54 for synchronously adjusting the folding assembly 5 and the folding assembly 2.

[0056] After the folding component 2 folds the raw material belt, the folded raw material belt has formed a double-layer form. In order to increase the packaging capacity of the folded bag, it is still necessary to fold the raw material belt that has formed a double-layer form so that the side of the raw material belt is in an "M" shape. When it is conveyed to the side close to the cutting device 12, the raw material belt is adsorbed by the first suction nozzle 511 and the second suction nozzle 512, so that the side of the raw material belt is easy to fold inward, and then under the pressure of the folding roller 52, the side of the raw material belt is folded inward, and because the first suction nozzle 511 and the second suction nozzle 512 are symmetrical along the surface of the conveyor belt 1, the middle part of the "raised" side of the raw material belt is aligned with the folding roller 52, so that the side of the raw material belt is folded.

[0057] The linkage part 54 provided at the same time can synchronously adjust the folding assembly 5 and the folding assembly 2. When it is necessary to produce folded bags, the folding assembly 5 and the folding assembly 2 can be simultaneously rotated to the working position through the linkage part 54. When it is necessary to produce flat bags, the linkage part 54 can make the folding assembly 5 and the folding assembly 2 rotate away from the working position, thereby realizing the switching of the device into different states according to production requirements.

[0058] The linkage member 54 includes a sliding rack 541 slidably arranged in the mounting frame 13, a sliding gear 542 is provided at the rotating shaft of the mounting block 41, the sliding gear 542 is meshed with the sliding rack 541, a driven gear 543 is provided in the mounting frame 13, the driven gear 543 is also meshed with the sliding rack 541, the folding roller 52 is rotatably connected with a connecting rod 544 between the mounting frame 13, the rotating shaft of the connecting rod 544 is provided with a driving gear 545, the driven gear 543 is transmission-connected with the driving gear 545, and a limiting member 55 for positioning the position of the folding roller 52 is also provided on the mounting frame 13; when the mounting block 41 is rotated to make the folding assembly 2 correspond to the raw material belt, the folding roller 52 rotates to correspond to the middle part of the side of the raw material belt.

[0059] When it is necessary to produce hemmed bags, it is necessary to rotate the mounting block 41 so that the abutment rod and the abutment plate correspond to the raw material belt. When the mounting block 41 rotates, it drives the sliding gear 542 to rotate, and the sliding gear 542 drives the sliding rack 541 to slide, and the sliding rack 541 drives the driven gear 543 to rotate, thereby driving the driving gear 545 to rotate, so as to realize the synchronous rotation of the two connecting rods 544, and realize the synchronous adjustment of the folding assembly 2 and the side assembly. That is, when it is necessary to produce hemmed bags, the hemming assembly 5 and the folding assembly 2 can be synchronously moved to the working position by rotating the mounting block 41. When it is necessary to produce flat bags, the hemming assembly 5 and the folding assembly 2 can be synchronously moved to a position away from the working state by rotating the mounting block 41.

[0060] At the same time, the position of the connecting rod 544 is limited by the set limit piece 55, so that the position of the mounting block 41 is fixed by the set positioning block 421, and the set limit piece 55 limits the position of the connecting rod 544, further improving the stability of the hemming bag production.

[0061] Reference Figure 5 The limiting member 55 includes a limiting block 551 elastically arranged on the mounting frame 13 , and the limiting block 551 is movably pressed against two side walls of the connecting rod 544 along the rotation direction of the connecting rod 544 .

[0062] When the mounting block 41 rotates until the hemming roller 52 is in the working state, the limit block 551 presses against the side of the connecting rod 544 under the action of the elastic restoring force, so that the connecting rod 544 is not easy to rotate, thereby achieving stable hemming;

[0063] When the mounting block 41 rotates until the folding roller 52 is away from the working state, the limit block 551 presses the opposite sides of the connecting rod 544 under the action of the elastic restoring force, making it difficult for the connecting rod 544 to rotate close to the working state, thereby reducing the interference of the folding roller 52 in the flat bag production process.

[0064] An electrostatic roller 6 is rotatably connected to the clamping plate 24 , which fits the surface of the raw material belt and is hollow. A steam component 62 for passing hot steam into the electrostatic roller 6 is provided on the mounting frame 13 , and a plurality of electrostatic holes 61 are densely distributed on the outer peripheral wall of the electrostatic roller 6 .

[0065] When producing folding bags, the raw material belt needs to be adsorbed to the bulge by the first adsorption nozzle 511 and the second adsorption nozzle 512, so as to facilitate M-shaped folding. In the conveying process, static electricity is likely to exist between the interlayers of the raw material belt, which causes the first adsorption nozzle 511 and the second adsorption nozzle 512 to easily generate side wrinkles when adsorbing the raw material belt. Therefore, when the electrostatic roller 6 arranged on the abutting plate 24 is conveyed and rotated in conjunction with the raw material belt, the steam part 62 conveys hot steam to the electrostatic roller 6, and the hot steam overflows from the electrostatic hole 61, thereby removing the static electricity generated on the inner side of the raw material belt, which is convenient for the subsequent adsorption of the raw material belt by the first adsorption nozzle 511 and the second adsorption nozzle 512, and is convenient for the subsequent folding operation.

[0066] At the same time, when producing folded bags, it is necessary to overcome the static electricity between the inner walls of the raw material belt, and when producing flat bags, it is necessary to use the static electricity between the inner walls of the raw material belt to keep the upper and lower sides of the raw material belt aligned. Therefore, the electrostatic roller 6 is set on the clamping plate 24. When producing folded bags, while the electrostatic roller 6 is clamping the raw material belt, the electrostatic roller 6 automatically removes the static electricity on the inner wall of the raw material belt, which is convenient for subsequent folding operations; when producing flat bags, it is necessary to rotate the mounting block 41 to store and fold the clamping plate 24. At this time, the electrostatic roller 6 is stored and folded accordingly, which facilitates the use of static electricity when making flat bags, and then facilitates the production of flat bags.

[0067] A pleating roller 7 is also rotatably arranged on the mounting frame 13. The pleating roller 7 is arranged between the clamping rod 22 and the folding roller 52. The pleating roller 7 is arranged to fit the surface of the raw material strip. There are two groups of pleating rollers 7. The two groups of pleating rollers 7 are arranged relatively symmetrically. An operating member 71 for synchronously adjusting the two groups of pleating rollers 7 is provided on the mounting frame 13.

[0068] No matter producing folded edge bags or flat bags, it is necessary to perform pleating operation on the folded parts, so as to achieve stable quality of finished packaging bags; the pleating roller 7 is provided to pleat the folded edges, so as to achieve stable folding operation and reduce subsequent insufficient folding caused by insufficient folding. At the same time, when producing flat bags, the pleating roller 7 is provided to fully flatten the cut raw material strip to keep the upper and lower sides of the raw material strip stably fitted.

[0069] The pleating roller 7 is arranged between the pressing rod 22 and the folding roller 52, and the pleating roller 7 is not easily offset due to the rotation of the mounting block 41, thereby achieving stable production of folding bags and flat bags.

[0070] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
