Description

Technical Field

[0001] The present invention relates to the technical field of packaging bag processing, and particularly relates to a film bag making machine. Background Art

[0002] In the prior art, a film bag making machine includes a feeding mechanism, a hemming mechanism, a transmission mechanism, a heat sealing mechanism and a shearing mechanism. The feeding mechanism is used for feeding. The hemming mechanism turns over the film transmitted by the feeding mechanism. Then, the film is transmitted to each mechanism through the transmission mechanism for processing, making the film more stable during transmission and having a better effect. The heat sealing mechanism is used to heat seal the film into a packaging bag unit, and the shearing mechanism is used to cut the packaging bag unit on the film to form a packaging bag monomer. However, there are at least the following defects: 1. When the film is transmitted to the shearing mechanism, the film is relatively thin and prone to static electricity reaction, causing the film to warp during shearing, resulting in a not-so-good shearing effect; 2. The position of the heat sealing mechanism cannot be adjusted, resulting in a relatively large limitation in use; 3. The tension of the film cannot be adjusted during use. Summary of the Invention

[0003] The object of the present invention: In order to overcome the defects of the prior art, the present invention provides a film bag making machine, which can eliminate static electricity when the film is transmitted to the cutting knife mechanism, the heat sealing mechanism can be adjusted according to requirements, and the tension of the film during transmission can also be adjusted through the tensioning mechanism.

[0004] This invention discloses a film bag making machine, including a base. A cutting mechanism and a sealing mechanism are sequentially arranged along the X-axis on the base. The cutting mechanism includes a cutter, a material placement table, and a first driving member that drives the cutter to slide. The cutter is slidably mounted on the material placement table along the Z-axis. The sealing mechanism includes a first heat-sealing head, a pressure plate, and a second driving member that drives the first heat-sealing head to slide along the Z-axis. The pressure plate is positioned along the sliding trajectory of the first heat-sealing head. A transmission mechanism is provided between the sealing mechanism and the cutting mechanism. The transmission mechanism includes at least two transmission rollers and a third driving member that drives the transmission rollers to rotate. The transmission rollers are arranged along the Y-axis, and a discharge channel is provided between adjacent transmission rollers. At least one transmission roller is linked to the output end of the third driving member. The machine also includes a folding mechanism and a feeding mechanism. The folding mechanism includes a folding bracket, which is inclined, with the upper end being the film inlet and the lower end being the film outlet. The two sides of the folding bracket gradually intersect from top to bottom. The feeding mechanism includes a feeding roller and a support frame. The feeding roller is rotatably mounted on the support frame. The characteristic feature is that the conveying roller has an annular groove arranged along its circumference, with several annular grooves spaced apart along the length of the conveying roller. A metal spring sleeve is provided on the conveying roller, and the metal spring is sleeved on the annular groove and protrudes from the annular groove. The machine base also has a tensioning mechanism, which includes several tensioning rollers arranged along the Y-axis and a fourth driving member for driving the tensioning rollers to slide. The fourth driving member can drive at least one tensioning roller to slide along the Z-axis. The machine base also has a first mounting base and an adjusting mechanism. A first heat-sealing head, a pressure plate, and a second driving member are all mounted on the first mounting base. The adjusting mechanism includes a rack mounted on the machine base and a first rotating shaft passing through the first mounting base. The rack is arranged along the X-axis on the machine base. A first gear adapted to the rack is sleeved on the first rotating shaft. The first rotating shaft is rotatably mounted on the first mounting base, and the first gear rotates synchronously with the first rotating shaft and meshes with the rack.

[0005] Using the above technical solution, when the film is conveyed to the discharge channel, the metal spring sleeve can eliminate static electricity on the film, resulting in better cutting performance when it is conveyed to the cutting mechanism. This reduces the occurrence of film lifting. The annular groove facilitates the installation of the metal spring sleeve and prevents it from slipping along the Y-axis during use. During film conveying, the fourth drive component can drive the tension roller to slide along the Z-axis. The sliding of the tension roller can tension the film during conveying, resulting in better processing performance. The cooperation between the first gear and the rack allows the first gear to move along the rack when it rotates, thereby driving the first rotating shaft to move. The first rotating shaft passes through the first mounting base, so it can also move the first mounting base. The first heat sealing head, the pressure plate, and the second drive component are installed as a whole through the first mounting base. When the first rotating shaft drives the first gear to rotate, it can drive the entire sealing mechanism to move along the X-axis. This allows the sealing mechanism to be adjusted along the X-axis as needed during use, making it more practical and meeting the needs of more customers.

[0006] A further embodiment of the present invention includes: the sealing mechanism further includes a second rotating shaft and a first mounting plate. The second rotating shaft is rotatably mounted on the first mounting base. A driven pulley and a first turntable are sleeved on the second rotating shaft. The driven pulley and the first turntable rotate synchronously with the second rotating shaft. A driving pulley is sleeved on the second driving member. The driving pulley and the driven pulley are linked by a belt. A first column is provided on the first turntable. The first column is arranged parallel to the second rotating shaft. The first heat sealing head is detachably connected to the first mounting plate. A second column is provided on the first mounting plate. A first connecting rod is provided between the first column and the second column. One end of the first connecting rod is hinged to the first column, and the other end is hinged to the second column.

[0007] With the above-described further configuration, the second drive component can drive the second rotating shaft to rotate through the cooperation of the driving and driven pulleys. When the second rotating shaft rotates, it drives the first turntable to rotate, thereby driving the first column to rotate. Since the first column and the second rotating shaft are parallel, the first turntable acts as an eccentric wheel when it rotates, thereby driving the first connecting rod to reciprocate along the Z-axis, which in turn drives the first heat sealing head to reciprocate along the Z-axis. This also transfers the weight of the first mounting plate and the first heat sealing head to the first column, which in turn transfers the weight to the second rotating shaft and the first mounting base. This prevents the weight from directly acting on the output end of the second drive component, thereby increasing the service life of the second drive component and reducing maintenance costs.

[0008] A further feature of the present invention is as follows: a second turntable is sleeved on the output end of the first driving member, the second turntable rotates synchronously with the output end of the first driving member, a third column is provided on the second turntable, the third column is arranged parallel to the output end of the first driving member, a fourth column is provided at one end of the cutter, a second connecting rod is provided between the third column and the fourth column, one end of the second connecting rod is hinged to the third column, and the other end is hinged to the fourth column. The rotation of the second turntable can drive the second connecting rod to slide along the Z-axis direction, thereby driving the cutter to slide along the Z-axis direction.

[0009] With the above further configuration, the first driving component can drive the second turntable to rotate. Since the third column and the output end of the first driving component are set in parallel, the second turntable will act as an eccentric wheel when it rotates. One end of the second connecting rod is hinged to the third column, so when the second turntable rotates, it will drive the second connecting rod to reciprocate along the Z-axis. Since the other end of the second connecting rod is hinged to the fourth column, the cutter can reciprocate along the Z-axis to cut.

[0010] A further feature of the present invention is as follows: a guide surface is provided on the material placement platform, a guide plate is provided on the cutter, the guide plate extends to the guide surface and fits closely therewith, and an adjustment component is also provided on the machine base to keep the side wall of the guide plate in contact with the guide surface. The adjustment component includes a connecting plate, a rocker arm and a tension spring. One end of the connecting plate is fixedly connected to the cutter. A first hinge shaft is also provided on the machine base. The middle part of the rocker arm is rotatably mounted on the machine base via the first hinge shaft. A first shaft and a second shaft are provided at both ends of the rocker arm in sequence. A sliding groove is provided on the connecting plate. The first shaft is inserted into the sliding groove and slides therewith, and the first shaft is rotatably mounted in the sliding groove. One end of the tension spring is fixedly connected to the second shaft, and the other end is fixedly connected to the machine base.

[0011] With the above-mentioned further configuration, when the cutter reciprocates along the Z-axis, the side wall of the guide plate is in contact with the guide surface. When the cutter slides and rotates relative to the guide surface, the connecting plate will drive the rocker arm to rotate circumferentially along the first hinge axis. As a result, the end of the rocker arm connected to the tension spring will swing. When swinging, the rocker arm can be reset according to the reset force of the tension spring, thereby driving the cutter to reset. This ensures that the side wall of the guide plate and the guide surface remain in close contact, making the cutter more stable during use and thus improving work efficiency.

[0012] A further feature of the present invention is that the tensioning mechanism includes a slide rail, which is disposed on the machine base along the Z-axis direction. A slider is provided on the slide rail, which is slidably disposed on the slide rail along the Z-axis direction. A fourth driving member is disposed on the slider, wherein at least one tensioning roller is fixedly disposed on the slider.

[0013] With the above further configuration, the slide rail can guide the slider when it slides, and the fourth driving component can drive the slider to slide along the Z-axis. When the slider slides, it can drive the tensioning roller installed on the slider to slide, thereby realizing the tensioning function.

[0014] A further provision of the present invention: the first mounting base is further provided with a second mounting plate, a first screw and a first guide rod, the first screw and the first guide rod being arranged along the Y-axis direction, the second mounting plate being provided with a first guide hole, the first guide rod passing through the first guide hole, the driven pulley, the first turntable, the second rotating shaft and the second driving component being all arranged on the second mounting plate, the second mounting plate being provided with a first threaded sleeve similar to the first screw, the first screw passing through the first threaded sleeve and threadedly engaging with the first threaded sleeve, the rotation of the first screw driving the second mounting plate to slide along the Y-axis direction, thereby realizing the driving of the first mounting plate to slide along the Y-axis direction.

[0015] With the above-mentioned further configuration, the cooperation between the first guide rod and the first guide hole can guide the second mounting plate when it slides. The cooperation between the first screw and the first screw sleeve can drive the second mounting plate to move along the Y-axis, thereby enabling the first heat sealing head to be adjusted along the X-axis and Y-axis, so as to better meet the needs of customers. Moreover, the use of threaded cooperation can ensure thread engagement when not adjusting, preventing the second mounting plate from sliding on its own, making it more stable during use.

[0016] A further provision of the present invention includes: a second mounting base located between the sealing mechanism and the tensioning mechanism; a second heat sealing head, a third rotating shaft, a second guide rod, a second screw, a third mounting plate, and a fifth driving member for driving the second heat sealing head to slide; the fifth driving member and the second heat sealing head mounted on the third mounting plate; the fifth driving member driving the second heat sealing head along the Z-axis; the second screw and the third rotating shaft rotatably mounted on the second mounting base; a second gear adapted to a rack mounted on the third rotating shaft; the second gear rotating synchronously with the third rotating shaft and meshing with the rack; a second guide hole in the third mounting plate; the second guide rod inserted into the second guide hole; and the third mounting plate slidingly mounted on the second guide rod along the Y-axis; and a second threaded sleeve in the third mounting plate; the second screw inserted into the second threaded sleeve and threadedly engaged with the second threaded sleeve.

[0017] With the above-mentioned further configuration, the second heat sealing head can perform the first heat sealing of the film, and then the first heat sealing head can perform the second heat sealing. The first heat sealing can be done by hot-point sealing, and the second heat sealing can be done by edge sealing, which makes the processing more efficient. The fifth driving component can drive the second heat sealing head to slide along the Z-axis. The second gear and rack can drive the third rotating shaft to move along the X-axis. Since the third rotating shaft passes through the second mounting base, when the third rotating shaft moves, it will drive the second mounting base to move along the X-axis, thereby driving the displacement adjustment of the second heat sealing head along the X-axis. The second guide rod and the second guide hole can guide the sliding of the third mounting plate. The second screw and the second screw sleeve can drive the third mounting plate to slide along the Y-axis, thereby driving the displacement adjustment of the second heat sealing head in the Y-axis direction. This allows the second heat sealing head to be adjusted according to needs, making it more practical and able to meet more customer needs. Attached Figure Description

[0029] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0030] In this article, the X-axis, Y-axis, and Z-axis directions refer to the X-axis, Y-axis, and Z-axis directions of a Cartesian coordinate system. The driving components mentioned in this article can all be motors, electric cylinders, and pneumatic cylinders, which can be purchased directly from the market and will not be described in detail here.

[0031] This invention discloses a film bag making machine, including a base 1. A cutting mechanism 2 and a sealing mechanism 3 are sequentially arranged along the X-axis on the base 1. The cutting mechanism 2 includes a cutter 211, a material feeding table 212, and a first driving member 213 that drives the cutter 211 to slide. The cutter 211 is slidably disposed on the material feeding table 212 along the Z-axis. The sealing mechanism 3 includes a first heat sealing head 311, a pressure plate 312, and a second driving member 313 that drives the first heat sealing head 311 to slide along the Z-axis. The pressure plate 312 is disposed along the sliding trajectory of the first heat sealing head 311. A transmission mechanism 4 is provided between the sealing mechanism 3 and the cutting mechanism 2. The transmission mechanism 4 includes at least two transmission rods. The system includes a roller 411 and a third driving member 412 that drives the transmission roller 411 to rotate. The transmission roller 411 is arranged along the Y-axis. A discharge channel 413 is provided between two adjacent transmission rollers 411. At least one transmission roller 411 is linked with the output end of the third driving member 412. The transmission roller 411 and the output end of the third driving member 412 can be linked by a belt and a pulley. The system includes a folding mechanism 5 and a feeding mechanism 6. The folding mechanism 5 includes a folding bracket 511, which is inclined. The upper end of the folding bracket 511 is the film inlet end 512, and the lower end is the film outlet end 513. The two sides of the folding bracket 511 gradually intersect from top to bottom. The feeding mechanism 6 includes a feeding roller 611 and a support frame 612. The feeding roller 611 rotates... The conveyor roller 411 is mounted on the support frame 612. In this embodiment, the conveyor roller 411 has an annular groove 414 arranged circumferentially thereon. Several annular grooves 414 are spaced apart along the length of the conveyor roller 411. The conveyor roller 411 is provided with a metal spring sleeve 415, which is located on the annular groove 414 and protrudes from the annular groove 414. The base 1 can also be provided with a tensioning shaft 416 for tightening the metal spring sleeve 415. The tensioning shaft 416 passes through the metal spring sleeve 415 and abuts against the inner wall of the metal spring sleeve 415, making the metal spring sleeve 415 more stable during use. The base 1 is also provided with a tensioning mechanism 7, which includes several tension rollers 71 arranged along the Y-axis. The machine base 1 includes a first mounting base 8 and an adjusting mechanism 9. The first heat sealing head 311, the pressure plate 312, and the second driving member 313 are all mounted on the first mounting base 8. The adjusting mechanism 9 includes a rack 911 mounted on the machine base 1 and a first rotating shaft 912 passing through the first mounting base 8. The rack 911 is mounted on the machine base 1 along the X-axis. A first gear 913, adapted to the rack 911, is sleeved on the first rotating shaft 912. The first rotating shaft 912 is rotatably mounted on the first mounting base 8. The first gear 913 rotates synchronously with the first rotating shaft 912 and meshes with the rack 911.When the film is conveyed to the discharge channel 413, the metal spring sleeve 415 can eliminate static electricity on the film, resulting in better cutting performance when it is conveyed to the cutting mechanism 2, reducing the occurrence of film warping. The annular groove 414 facilitates the installation of the metal spring sleeve 415, and when the metal spring sleeve 415 is fitted onto the annular groove 414, it prevents slippage along the Y-axis during use. During film conveying, the fourth drive component 712 can drive the tension roller 711 to slide along the Z-axis. The sliding of the tension roller 711 can tension the film during conveying, resulting in better processing performance. The first gear 913... The engagement of the first gear 913 with the rack 911 allows the first gear 913 to move along the rack 911 when it rotates, thereby driving the first rotating shaft 912 to move. Since the first rotating shaft 912 passes through the first mounting base 8, it can also drive the first mounting base 8 to move. The first heat sealing head 311, the pressure plate 312, and the second driving component 313 are integrated through the first mounting base 8. This allows the first rotating shaft 912 to drive the first gear 913 to rotate, which in turn drives the entire edge sealing mechanism 3 to move along the X-axis. This means that during use, the edge sealing mechanism 3 can be adjusted and moved along the X-axis as needed, making it more practical and meeting the needs of more customers.

[0032] The sealing mechanism 3 further includes a second rotating shaft 314 and a first mounting plate 315. The second rotating shaft 314 is rotatably mounted on the first mounting base 8. A driven pulley 316 and a first turntable 317 are sleeved on the second rotating shaft 314. The driven pulley 316 and the first turntable 317 rotate synchronously with the second rotating shaft 314. A driving pulley 318 is sleeved on the second driving member 313. The driving pulley 318 and the driven pulley 316 are linked by a belt. A first column 319 is provided on the first turntable 317. The first column 319 is arranged parallel to the second rotating shaft 314. The first heat sealing head 311 is detachably connected to the first mounting plate 315. A second column 320 is provided on the first mounting plate 315. A first connecting rod 321 is provided between the first column 319 and the second column 320. One end of the first connecting rod 321 is hinged to the first column 319, and the other end is hinged to the second column 320. The cooperation of pulley 318 and driven pulley 316 allows the second drive component 313 to drive the second rotating shaft 314 to rotate. When the second rotating shaft 314 rotates, it drives the first turntable 317 to rotate, which in turn drives the first column 319 to rotate. Since the first column 319 and the second rotating shaft 314 are parallel, the first turntable 317 acts as an eccentric wheel when it rotates, thereby driving the first connecting rod 321 to reciprocate along the Z-axis, which in turn drives the first heat sealing head 311 to reciprocate along the Z-axis. It also transfers the weight of the first mounting plate 315 and the first heat sealing head 311 to the first column 319, which in turn transfers the weight to the second rotating shaft 314, and finally to the first mounting base 8. This prevents the weight from directly acting on the output end of the second drive component 313, thereby increasing the service life of the second drive component 313 and reducing maintenance costs.

[0033] A second turntable 214 is fitted onto the output end of the first driving component 213. The second turntable 214 rotates synchronously with the output end of the first driving component 213. A third column 215 is provided on the second turntable 214, and the third column 215 is arranged parallel to the output end of the first driving component 213. A fourth column 216 is provided at one end of the cutter 211. A second connecting rod 217 is provided between the third column 215 and the fourth column 216. One end of the second connecting rod 217 is hinged to the third column 215, and the other end is hinged to the fourth column 216. Rotation of the second turntable 214 can drive the second connecting rod 217 to slide along the Z-axis. This causes the cutter 211 to slide along the Z-axis. The first drive member 213 can drive the second turntable 214 to rotate. Since the third column 215 and the output end of the first drive member 213 are set in parallel, the second turntable 214 will act as an eccentric wheel when it rotates. One end of the second connecting rod 217 is hinged to the third column 215. So when the second turntable 214 rotates, it will drive the second connecting rod 217 to reciprocate along the Z-axis. Since the other end of the second connecting rod 217 is hinged to the fourth column 216, the cutter 211 can reciprocate along the Z-axis to cut.

[0034] The material placement platform 212 is provided with a guide surface 218, and the cutter 211 is provided with a guide plate 219. The guide plate 219 extends to the guide surface 218 and fits closely with it. The machine base 1 is also provided with an adjusting component 10 for keeping the side wall of the guide plate 219 in contact with the guide surface 218. The adjusting component 10 includes a connecting plate 1011, a swing rod 1012, and a tension spring 1013. One end of the connecting plate 1011 is fixedly connected to the cutter 211. The machine base 1 is also provided with a first hinge shaft 1014. The middle part of the swing rod 1012 is rotatably mounted on the machine base 1 via the first hinge shaft 1014. The two ends of the swing rod 1012 are provided with a first shaft 1015 and a second shaft 1016 in sequence. The connecting plate 1011 is provided with a sliding groove 1017. The first shaft 1015 is inserted into the sliding groove 1017 and slides with it. 5. The spring 1013 is rotatably set in the slide groove 1017. One end of the spring 1013 is fixedly connected to the second shaft 1016, and the other end is fixedly connected to the base 1. When the cutter 211 reciprocates along the Z-axis, the side wall of the guide plate 219 is in contact with the guide surface 218. When the cutter 211 slides and rotates relative to the guide surface, the connecting plate 1011 will drive the swing rod 1012 to rotate circumferentially along the first hinge axis 1014. As a result, the end of the swing rod 1012 connected to the spring 1013 will swing. When swinging, the swing rod 1012 can be reset according to the reset force of the spring 1013, thereby driving the cutter 211 to reset. This makes the side wall of the guide plate 219 and the guide surface 218 close to each other, making the cutter 211 more stable during use, thereby improving work efficiency.

[0035] The tensioning mechanism 7 further includes a slide rail 713, which is mounted on the base 1 along the Z-axis. A slider 714 is mounted on the slide rail 713 and slides along the Z-axis. A fourth driving member 712 is mounted on the slider 714. At least one tensioning roller 711 is fixedly mounted on the slider 714. The slide rail 713 can guide the slider 714 when it slides. The fourth driving member 712 can drive the slider 714 to slide along the Z-axis. When the slider 714 slides, it can drive the tensioning roller 711 mounted on the slider 714 to slide, thereby achieving the tensioning function.

[0036] The first mounting base 8 is also provided with a second mounting plate 811, a first screw 812, and a first guide rod 813. The first screw 812 and the first guide rod 813 are arranged along the Y-axis. The second mounting plate 811 is provided with a first guide hole 814, and the first guide rod 813 passes through the first guide hole 814. The driven pulley 316, the first turntable 317, the second rotating shaft 314, and the second driving member 313 are all arranged on the second mounting plate 811. The second mounting plate 811 is also provided with a first threaded sleeve 815 that is similar to the first screw 812. The first screw 812 passes through the first threaded sleeve 815 and is threadedly engaged with the first threaded sleeve 815. The rotation of the first mounting plate 811 causes it to slide along the Y-axis, thereby driving the first mounting plate 315 to slide along the Y-axis. The cooperation between the first guide rod 813 and the first guide hole 814 guides the second mounting plate 811 during sliding. The cooperation between the first screw 812 and the first screw sleeve 815 moves the second mounting plate 811 along the Y-axis, allowing the first heat sealing head 311 to be adjusted along the Y-axis to better meet customer needs. Furthermore, the threaded engagement prevents the second mounting plate 811 from sliding on its own, making it more stable during use.

[0037] The base 1 is also provided with a second mounting seat 11, which is located between the sealing mechanism 3 and the tensioning mechanism 7. The second mounting seat 11 is provided with a second heat sealing head 1111, a third rotating shaft 1112, a second guide rod 1113, a second screw 1114, a third mounting plate 1115, and a fifth driving member 1116 for driving the second heat sealing head 1111 to slide. The fifth driving member 1116 and the second heat sealing head 1111 are disposed on the third mounting plate 1115. The fifth driving member 1116 can drive the second heat sealing head 1111 along the Z-axis direction. The second screw 1114 and the third rotating shaft 1112 are rotatably disposed on the second mounting plate 1115. On the mounting base 11, a second gear 1117 adapted to the rack 911 is sleeved on the third rotating shaft 1112. The second gear 1117 rotates synchronously with the third rotating shaft 1112 and meshes with the rack 911. The third mounting plate 1115 is also provided with a second guide hole 1118. A second guide rod 1113 is inserted into the second guide hole 1118, and the third mounting plate 1115 is slidably mounted on the second guide rod 1113 along the Y-axis direction. The third mounting plate 1115 is also provided with a second threaded sleeve 1119. A second screw 1114 is inserted into the second threaded sleeve 1119 and engages with the second threaded sleeve 1119. The threaded connection allows the second heat-sealing head 1111 to perform the first heat sealing of the film, followed by the second heat sealing through the first heat-sealing head 311. The first heat sealing can be done by hot-point sealing, and the second heat sealing can be done by edge sealing, resulting in higher processing efficiency. The fifth drive component 1116 can drive the second heat-sealing head 1111 to slide along the Z-axis. The second gear 1117 and rack 911 cooperate to drive the third rotating shaft 1112 to move along the X-axis. Since the third rotating shaft 1112 passes through the second mounting base 11, the movement of the third rotating shaft 1112... When the second heat sealing head 11 is moved along the X-axis, the second mounting base 11 moves along the X-axis, thereby adjusting the displacement of the second heat sealing head 1111 along the X-axis. The second guide rod 1113 and the second guide hole 1118 cooperate to guide the third mounting plate 1115 when it slides. The second screw 1114 and the second screw sleeve 1119 cooperate to drive the third mounting plate 1115 to slide along the Y-axis, thereby adjusting the displacement of the second heat sealing head 1111 in the Y-axis direction. This allows the second heat sealing head 1111 to be adjusted according to requirements, making it more practical and able to meet more customer needs.
