Description
Technical Field
[0001] This invention relates to the field of bag processing equipment, and more specifically to a high-speed processing equipment for multifunctional woven bags. Background Technology
[0002] Current multi-functional woven bags include market bags, chemical bags, and feed bags. The processing of these bags all uses the same method: first, the bag body is cut into multiple sections, then flattened by a flattening mechanism. Next, a conveying mechanism transports the bag body to a sewing mechanism for sewing at one end. After sewing, a plastic bag is manually placed inside the bag body. Then, workers sew the plastic bag to the top of the bag body, connecting the bag body and the plastic bag together. This process relies heavily on manual labor, resulting in low efficiency and high labor costs, which does not meet the demands of modern automated processing. Summary of the Invention

[0021] The invention will now be further described with reference to the accompanying drawings.
[0022] like Figure 1-10As shown, a high-speed processing device for multifunctional woven bags includes a bag unwinding mechanism 1, a bag cutting mechanism 2, a bag conveying mechanism 17, an inner bag nesting mechanism 32, and a bag sewing mechanism 51. The bag cutting mechanism 2 is located to the right of the bag unwinding mechanism 1. Uncut rolls of bag material are unwound through the bag unwinding mechanism 1. Tensioning rollers 3 are located on both sides of the bag cutting mechanism 2. When the unwound bag material reaches the bag cutting mechanism 2, the tensioning rollers 3 tighten the bag material for easy cutting. A bag conveying mechanism 17 is located to the right of the bag cutting mechanism 2, which transports the cut bags backwards. The bag conveying mechanism 17 is conveyed backward. A bag opening mechanism 27 is provided above the bag conveying mechanism 17, and an inner bag nesting mechanism 32 is provided on the left side of the bag opening mechanism 27. When the bag is conveyed to the bag opening mechanism 27, the bag is opened by the bag opening mechanism 27, and the inner bag is embedded into the bag by the inner bag nesting mechanism 32. The bag opening mechanism 27 presses the bag closed, and the bag continues to be conveyed backward. A bag sewing mechanism 51 is provided on both sides of the end of the bag conveying mechanism 17. The bag sewing mechanism 51 realizes the sewing of both ends of the bag, including the rolled edge of the left end of the bag and the sealing of the right end of the bag.
[0023] The bag unwinding mechanism 1 includes a roller and multiple round rollers. Supports are provided at both ends of the roller, and arc-shaped grooves are opened at the top of the supports for the roller to be inserted. Two supports are bolted to the frame. The bag roll is sleeved on the roller, and the roller rotates by placing its two ends on the supports. Multiple round rollers are mounted on the frame via bearings, and these rollers are staggered vertically. The bag unwound from the roller is wound around the round rollers. A horizontal platform is fixed to the top right side of the frame by welding. A feeding roller driven by a motor is mounted on the top of the platform via bearings and bearing seats. The feeding roller presses the bag onto the platform. A bag cutting mechanism 2 is located above and to the right of the feeding roller, thus achieving bag unwinding.
[0024] The bag cutting mechanism 2 includes a lifting cutting blade 4, a lifting seat 5, and a first crank rocker mechanism 6. A conveyor plate 7 is located at the bottom of the lifting cutting blade 4, and the conveyor plate 7 is in contact with the table surface with both top surfaces on the same plane. Mounting columns 8 are fixed to the front and rear edges of the conveyor plate 7 by bolts (the bottom of the rear mounting column 8 has a notch to allow for the rearward conveying of the cut bag, meaning that after the bag is cut, it can be directly conveyed backward without needing to move to the right and misalign with the mounting column 8 before being conveyed backward). A first crank rocker mechanism 6, driven by a motor, is located on the top surface of the two mounting columns 8 (the first crank rocker mechanism 6 includes a rotating rod, an eccentric wheel, a ring, and a pressure...). Rod 16, the two ends of the rotating rod are mounted on two mounting columns via bearings. One end of the rotating rod is fixed to the output shaft of the motor by welding, thus realizing the rotation of the rotating rod. Two sets of eccentric wheels are fixed to the rotating rod by welding, and a ring is fitted on the outer circumference of each set of eccentric wheels. A rocker arm is hinged to the outer wall of the ring. A vertical guide rail 9 is fixed to the inner side of the mounting column 8 by welding. A lifting seat 5 is set between the two mounting columns 8. The two sides of the lifting seat 5 are engaged with the guide rail 9 of the mounting column 8 and slide up and down. The bottom of the pressure rod 16 of the first crank rocker mechanism 6 is hinged to the top of the lifting seat 5. A lifting cutter 4 is installed at the bottom of the lifting seat 5 by bolts. Tensioning wheels 3 are installed on both sides of the cutting blade 4. Two extension plates extending to the left and right sides are welded to both sides of the lifting base 5, with each extension plate close to the front and rear ends of the lifting base 5. Each extension plate has a vertically arranged oblong hole 11. A lifting block 12 is inserted into each oblong hole 11, and the lifting block 12 moves up and down within the oblong hole 11. A spring is installed in the lifting block 12 and the oblong hole 11. The bottom of the spring is welded to the top of the lifting block 12, and the top of the spring rests against the top of the oblong hole 11. The two ends of the tensioning wheels 3 are mounted on the lifting blocks 12 via bearings. A tensioning cylinder 13 is installed on the top of the lifting blocks 12 by bolts. An eccentric block 14 extending outward is installed on the circumferential edge by welding. A pull rod 15 is hinged between the eccentric block 14 and the tensioning cylinder 13. The top of the pull rod 15 is hinged to the piston rod of the tensioning cylinder 13, and the other end of the pull rod 15 is hinged to the eccentric block 14. The forward and reverse rotation of the tensioning wheel 3 is achieved by the lifting and retraction of the tensioning cylinder 13. The outer circumference of the tensioning wheel 3 is glued with a rubber ring. During operation, the lifting seat 5 descends, the tensioning wheel 3 presses against the top surface of the bag, the tensioning cylinder 13 rises, and the tensioning wheel 3 rotates outward, thus tensioning the bag between the two tensioning wheels 3. The lifting seat 5 continues to descend, and the lifting cutter 4 cuts the bag. The lifting seat 5 then rises.
[0025] The bag conveying mechanism 17 includes a conveying plate 18, a reciprocating conveying assembly 19, a clamping assembly 23, and a woven bag conveyor belt 26. The conveying plate 18 is connected to the right end of the conveying plate 7, and the two sets of top surfaces are flush. The reciprocating conveying assembly 19 is provided at the bottom of the conveying plate 18, and the reciprocating conveying assembly 19 is located at the front and middle sections of the conveying plate 18. Multiple clamping assemblies 23 are installed on the reciprocating conveying assembly 19. Long strip-shaped grooves (multiple long strip-shaped grooves are arranged side by side, and the multiple long strip-shaped grooves are arranged longitudinally, and the clamping assemblies 23 move reciprocally longitudinally in the long strip-shaped grooves) are provided on the upper part of the rear section of the conveying plate 18. The woven bag conveyor belt (two woven bag conveyor belts are mounted on two round rollers on the conveyor plate 18, the round rollers are driven by a motor, and the two round rollers are mounted on a gantry frame via bearings and bearing seats. The bottom of the gantry frame is bolted to the left and right sides of the conveyor plate 18, and the woven bag conveyor belts press the bags onto the conveyor plate 18 for conveying); the reciprocating conveying assembly 19 includes a linkage rod 20, a translation plate 21, and a second crank rocker mechanism 22. The translation plate 21 is located below the conveyor plate 18, and multiple translation plates 21 are slidably connected to the bottom of the conveyor plate 18 (each translation plate 21 has a fixed top by welding). A sliding rail is provided, and a groove is opened at the bottom of the conveyor plate 18 for the sliding rail to engage, thus achieving a sliding fit between the translation plate 21 and the conveyor plate 18. Multiple translation plates 21 are arranged longitudinally side by side, and the bottom of the multiple translation plates 21 are fixedly connected to the same linkage rod 20 by welding. The multiple translation plates 21 move synchronously. A second crank rocker mechanism 22 driven by a motor is installed at the bottom of the front end of the conveyor plate 18. The rocker arm of the second crank rocker mechanism 22 is hinged to the linkage rod 20. The longitudinal reciprocating sliding of the linkage rod 20 is achieved through the second crank rocker mechanism 22, thus realizing the reciprocating movement of the translation plate 21. A mounting plate is installed on the top surface of the rear end of each translation plate 21. There is a clamping assembly 23, which includes a swing clamping block 24 and a support plate 25. The support plate 25 is installed on the top surface of the translation plate 21 by bolt fastening. The support plate 25 is flush with the top surface of the conveying plate 18. A swing clamping block 24 (the swing clamping block 24 is an L-shaped block) is installed on the rear end of the translation plate 21. Multiple swing clamping blocks 24 on a translation plate 21 are installed on the same rotating shaft by welding. The rotating shaft is installed on the translation plate 21 by bearings. The rotating shaft is driven by a motor. The rotation of the rotating shaft causes the swing clamping block to swing. When the swing clamping block 24 presses on the support plate 25, the swing clamping block 24 and the support plate 25 clamp the rear end of the bag.During operation, the translation plate 21 moves forward under the action of the second crank-rocker mechanism 22. The support plate 25 is located below the rear end of the bag body. The swing clamp 24 swings counterclockwise and presses against the support plate 25. The translation plate 21 moves backward under the action of the second crank-rocker mechanism 22, thus driving the bag body to move backward. When it moves into position, the swing clamp 24 swings clockwise into the elongated groove. The top of the swing clamp 24 is lower than the top surface of the conveying plate 18, thus achieving equal-volume conveying of the bag body. The bag opening mechanism 27 is located above the reciprocating conveying assembly 19, and the bag sewing mechanism 51 is located on the left and right sides of the woven bag conveyor belt 26. The woven bag conveyor belt 26 achieves uniform-speed conveying of the bag body.
[0026] The bag opening mechanism 27 includes a lifting plate 28, a negative pressure component 29, and a pressure plate 30. An mounting plate 31 is positioned above the conveying mechanism. Columns are bolted between the mounting plate 31 and the left and right edges of the conveying plate 18. Lifting plates 28 are positioned below both ends of the mounting plate 31. A cylinder for raising and lowering the lifting plates 28 is positioned between the lifting plates 28 and the mounting plate 31. The cylinder body is bolted to the mounting plate 31, and the piston rod is bolted to the lifting plates 28. The lifting plates 28 are raised and lowered by the extension and retraction of the cylinders. A negative pressure component 29 is positioned at the bottom of each lifting plate 28 and on the conveying plate 18 at the bottom of the lifting plate 28. (The negative pressure component 29 is a negative pressure head connected to a negative pressure pump, which generates...) The negative pressure adsorption bag surface has countersunk holes for the negative pressure head to be inserted on the top surface of the conveying plate 18 and the bottom of the lifting plate 28 (the countersunk holes on the top surface of the conveying plate and the bottom of the lifting plate are arranged vertically opposite each other). The lifting plate 28 presses on both ends of the bag, and the negative pressure component 29 adsorbs the top and bottom surfaces of both ends of the bag. A pressure plate 30 is installed on the lifting plate 28 and presses on the bag. When working, the bag moves below the lifting plate 28, so the lifting plate 28 descends and presses on the bag. The negative pressure component 29 adsorbs the outer wall of the bag, and the lifting plate 28 rises, thus opening the bag. The inner bag nesting mechanism 32 on the left side places the plastic inner bag into the bag. Then the lifting plate 28 descends, the negative pressure component 29 releases the negative pressure, and the lifting plate 28 rises, conveying the bag backward.
[0027] The inner bag nesting mechanism 32 includes an inner bag conveying assembly 33, an inner bag sealing assembly 43, and an inner bag clamping assembly 44. A roller 34 is mounted on the left end of the inner bag conveying assembly 33 via a bearing. A rolled inner bag is wound on the roller 34. The inner bag is conveyed through the inner bag conveying assembly 33. The inner bag conveying assembly 33 consists of multiple pairs of closely fitting rollers 35, each pair of rollers 35 positioned vertically. Each pair of rollers 35 is mounted on the top surface of the machine via bearings and bearing seats. The inner bag is conveyed through the rollers 35. A flat plate 36 is welded to the right end of the inner bag conveying assembly 33. The inner bag sealing assembly 43 is positioned above the flat plate 36 near the rollers 35. Located at the left end of the flat plate 36, the inner bag sealing assembly 43 is fitted with a cutter 37 by bolts on the side near the roller 35. The inner bag sealing assembly 43 is a heating strip, the top of which is bolted to the sealing plate. Hydraulic cylinders are bolted between the front and rear ends of the sealing plate and the front and rear ends of the flat plate. The extension and retraction of the hydraulic cylinders presses the heating strip onto the flat plate 36, thus achieving heat sealing. The cutter 37 is fixed to the left side of the sealing plate by welding. When the heat sealing strip is pressed onto the flat plate 36, the cutter cuts the inner bag, thus sealing the left end of the inner bag. On the ground to the right of the flat plate 36, a bearing and bearing seat are installed... The device is equipped with a horizontal rotating wheel 38 driven by a stepper motor. Multiple inner bag clamping assemblies 44 arranged in a circular array are welded onto the outer circumference of the rotating wheel 38. Each inner bag clamping assembly 44 is a U-shaped rod 45 with a notch at one end, forming two L-shaped rods. The notch in the U-shaped rod 45 allows space for the pressure plate 30. Both ends of the U-shaped rod 45 are hollow, and guide rods 46 extend into the hollow sections. The U-shaped rod 45 slides on the guide rods 46 (the guide rods 46 are multi-faceted to prevent relative rotation between the U-shaped rods and the guide rods). The other end of the guide rods 46 is welded onto the rotating wheel 38. An outwardly extending stop 47 is installed at the root of the U-shaped rod 45 by welding. A pusher linear motor 48 is installed on the ground on both sides of the rotating wheel 38 by bolt fastening. Two sets of pusher linear motors 48 are respectively set on the front and rear sides of the rotating wheel 38. The two sets of pusher linear motors 48 on the same side are arranged side by side. The mover of the pusher linear motor 48 pushes the stop 47 to move outward, thus realizing the outward lifting of the U-shaped rod 45. The pusher linear motor 48 pushes the stop 47. A spring is installed on the guide rod 46. The two ends of the spring are fixed to the rotating wheel and the U-shaped rod by welding. The spring realizes the inward movement of the U-shaped rod 45 back to its original position.An inner bag conveyor belt 49 is embedded in the flat plate 36. Multiple negative pressure suction heads are bolted to the outer wall of the inner bag conveyor belt 49. A lifting negative pressure suction head is positioned above the right end of the inner bag conveyor belt 49. A gantry frame is bolted to the right end of the flat plate, and a cylinder is bolted to the bottom of the gantry frame. A negative pressure suction head is bolted to the piston rod of the cylinder. During operation, the roll 34 unwinds to convey the inner bag to the right. The inner bag is sealed by a heating strip. During sealing, a cutter 37 on the left cuts the inner bag, and the right end of the inner bag is sucked up by the negative pressure suction head on the inner bag conveyor belt 49. The right end of the bag is then conveyed to the right end of the flat plate 36 along with the inner bag conveyor belt 49. A U-shaped rod 45 is rotated by a rotating wheel 38 to be positioned opposite the inner bag. The negative pressure suction head located above the right end of the flat plate... The suction head descends to adsorb the right end of the inner bag. After adsorption is complete, the negative pressure suction head located above the right end of the plate quickly rises to open the bag opening. The U-shaped rod located horizontally to the left of the rotating wheel 38 is pushed upward by the pusher linear motor 48, thus extending the U-shaped rod into the inner bag. The negative pressure is released by the negative pressure suction head above the right end of the plate 36 via the inner bag conveyor belt 49. At the same time, the pusher linear motor 48 located on the left moves to the right to return to its original position. The U-shaped rod quickly moves to the right to return to its original position under the action of the spring. After the U-shaped rod 45 returns to its original position, it rotates clockwise, thus moving the actuator of the pusher linear motor 48 located on the right side of the inner bag conveyor belt rotating wheel 38 to the right and pushing the stop block 47 to the right. The inner bag and the U-shaped rod extend into the bag body. The lifting plate 28 descends, and the pressure plate 30 presses down on the bag body and the inner bag. The notch on the U-shaped rod is mainly to allow space for the pressure plate 30, preventing the inner bag from following the U-shaped rod out of the bag body when it exits.
[0028] A glue spraying assembly 39 is installed on the ground behind the rotating wheel 38. The glue spraying assembly 39 includes a mounting frame 40, a glue spraying head 41, and a telescopic assembly 42. A groove is cut into the mounting frame 40, forming a U-shape. The outer side of the inner bag opening extends into the groove. The glue spraying head 41 is installed inside the groove of the mounting frame 40 by bolts. The glue spraying head 41 applies glue to the outer side of the inner bag opening. The telescopic assembly 42 is installed on the mounting frame 40 by welding. The telescopic assembly 42 includes a straight rod, a telescopic cylinder, and a cylinder. A column is installed on the ground by bolts. Multiple telescopic cylinders are installed side by side on the column by bolts. The straight rod passes through the telescopic cylinder and slides back and forth along the telescopic cylinder. The rear end of the straight rod is connected to the column by bolts. Equipped with a cylinder (the straight rod slides back and forth through the extension and retraction of the cylinder), the mounting frame 40 extends and retracts via the telescopic component 42, allowing the bag to be inserted into the groove of the mounting frame 40. During operation, when the U-shaped rod with the inner bag is rotated directly above the rotating wheel 38 and the U-shaped rod is vertically positioned, the mounting frame 40 is lifted forward by the cylinder, allowing the bag opening to be inserted into the groove of the mounting frame 40. The glue spray head 41 sprays glue onto the outer wall of the inner bag opening. The glue spray head 41 is connected to a box containing glue via a pipe, and a pump body is installed on the pipe via a threaded connector. When the inner bag is inserted into the bag body, the lifting plate presses down to press the inner bag and the bag body together, thus bonding the outer wall of the inner bag opening to the inner wall of the bag opening with glue, facilitating subsequent hemming.
[0029] A hemming and sewing assembly 52 is installed on the left side of the conveyor plate 18 near the rear end. A woven bag sewing machine for sealing the edge is installed on the right side of the conveyor plate 18 near the rear end by bolts. When the right end of the bag passes through the woven bag sewing machine, the right end of the bag is sewn. The hemming and sewing assembly 52 includes a hemming assembly 53, a wireless overlock assembly 62, and a heating plate 64. The hemming assembly 53 and the wireless overlock assembly 62 are arranged front and rear. The hemming assembly 53 includes a hemming tension assembly 54, a hemming rod 59, and a folding rod 60. The hemming tension assembly 54 consists of two sets of suction rods 55, which are hollow rods and connected to a negative pressure pump. A negative pressure hole 56 is opened on the side of the suction rod 55 facing the bag. The suction rod is located at the top. A cylinder is installed between the suction rod 55 and the top surface of the conveyor plate 18 by bolts. The extension and retraction of the cylinder raises and lowers the suction rod 55. The suction rod 55 at the bottom is embedded in the conveyor plate 18, and the top surface of the suction rod 55 at the bottom is flush with the top surface of the conveyor plate. When the bag is conveyed between the two suction rods 55 by the woven bag conveyor belt, the woven bag conveyor belt stops working, and the suction rod 55 at the top moves upward to open the bag. There is a rightward-extending hemming notch on the left side of the conveyor plate, and a translation seat 57 is installed in the notch. A translation component 58 is provided between the translation seat 57 and the bag conveying mechanism 17 to move the translation seat 57 toward the bag (the translation component 58 includes a hemming side plate, a hemming straight rod, and a hemming cylinder, and the hemming side plate is connected by...). Bolts are installed on the left side of the conveyor plate. A straight edge-rolling rod extends through the edge-rolling side plate into the edge-rolling notch. A translation seat 57 is bolted to one end of the straight edge-rolling rod that extends into the edge-rolling notch. An edge-rolling cylinder is installed between the left side of the translation seat 57 and the edge-rolling side plate, secured by bolts. The translation seat 57 moves left and right by extending and retracting the edge-rolling cylinder. Two edge-rolling rods 59 are installed on the right side of the translation seat 57, arranged front and back. A folding edge rod 60 is hinged to the outside of each edge-rolling rod 59. A torsion spring is welded to the hinge point between the folding edge rod 60 and the edge-rolling rod 59. The torsion spring returns the folding edge rod 60 to its original position. The initial angle between the folding edge rod 60 and the edge-rolling rod 59 is an acute angle. When the edge-rolling rod 59 is lifted, the folding edge rod 60 pushes the sides of the bag... The edges are folded inwards. An opening module 61 is installed on each of the two edge-rolling rods 59. The opening module 61 is a bidirectional cylinder. A slide rail is welded to the base of each edge-rolling rod 59. A groove is provided on the right side of the translation seat 57 for the slide rail to engage with it, allowing the edge-rolling rod 59 to move left and right along the groove. A bidirectional cylinder is bolted to the right side of the translation seat 57. The piston rod of the bidirectional cylinder is fixed to each of the two edge-rolling rods 59 with bolts. During operation, the bidirectional cylinder retracts, the two edge-rolling rods 59 move inwards, the edge-rolling cylinder rises, the translation seat 57 moves towards the bag opening, the edge-rolling rods extend into the bag opening, the bidirectional cylinder rises again, and the edge-rolling rods 59 expand outwards, so that the edge-rolling rods are inside the bag and the folding rod 60 is outside the bag.Meanwhile, there is a gap between the edge-rolling rod 59 and the inner wall of the bag. The edge-rolling rod 59 continues to rise, and the folding rod presses against the two edges of the bag opening and folds inward. At the same time, the folding rod swings to the left and continues to rise through the vertical cylinder. The edge-rolling rod contacts the inner wall of the bag, and the folding rod and the edge-rolling rod fit together, thus completing the edge-rolling of the bag. After the edge-rolling is completed, the bidirectional cylinder retracts. Through the retraction of the edge-rolling cylinder, the edge-rolling rod exits the bag. At the same time, the suction rod 55 presses down to form a crease on the edge of the bag, preventing it from returning to its original position after edge-rolling. The woven bag conveyor belt then moves the bag to the next processing step. A wireless locking assembly 62 and a heating plate 64 are installed on the conveyor plate behind the edge-rolling assembly 53. A locking notch is opened on the left side of the conveyor plate 18. The wireless locking assembly 62 and the heating plate 64 are installed in place. On the shifting assembly 65, the wireless overlock assembly 62, the heating plate 64, and the shifting assembly 65 are all installed within the overlock notch. The heating plate 64 extends into the bag body via the shifting assembly 65. The shifting assembly 65 includes an overlock slide rail, an overlock shifting seat, and an overlock cylinder. The overlock slide rail is fixed to the inside of the overlock notch by welding. The overlock shifting seat is installed within the overlock notch, with both ends engaging with the overlock slide rail and moving left and right along the overlock slide rail. An overlock plate is installed at the left end of the overlock notch by bolts. An overlock cylinder is installed between the overlock plate and the overlock shifting seat by bolts. The overlock shifting seat is moved horizontally by the lifting / retracting of the overlock cylinder. The heating plate 64 is fixed to the overlock by welding. On the right side of the edge displacement seat, a cavity is provided in the heating plate, and an electrically powered heating wire is inserted into the cavity. Wireless edge-locking components 62 press against the upper and lower sides of the bag body. There are two sets of wireless edge-locking components 62, located on the upper and lower sides of the heating plate 64. Each wireless edge-locking component 62 is a pressing wheel 63 driven by a motor, with serrated edges. The pressing wheel 63 presses against the heating plate 64. A swing component 66 is provided between the two sets of pressing wheels 63, allowing the two sets of pressing wheels 63 to open and close. The swing component 66 includes a swing arm, an edge-locking pull rod, an edge-locking straight rod, and an edge-locking screw. Two swing arms are hinged to the right side of the edge-locking displacement seat, located on the upper and lower sides of the heating plate. A motor driving the pressing wheel 63 is bolted to each swing arm. A locking rod is hinged to the middle of each swing arm, and a locking straight rod is hinged to the other end of each locking rod. The locking straight rod passes through the locking displacement seat and moves left and right. The two locking straight rods are welded to the same locking plate. A locking screw driven by a motor is installed between the left side of the locking displacement seat and the locking plate. The locking screw passes through the locking plate and is threaded, thus achieving the locking edge. During operation, since the bag opening is not locked after folding, and the side of the heating plate 64 facing the bag is inclined, when the locking displacement seat moves to the right, the heating plate extends into the bag opening, the locking screw engages, and the swing arm swings towards the heating plate.The pressing roller presses the bag body against the heating plate while the bag body moves, thus achieving edge locking. The multiple stepper motors, electric motors, cylinders, and hydraulic cylinders in this application are all controlled by a PLC controller, allowing each mechanism to work sequentially to complete the bag body processing.
