Description

Technical Field

[0001] This invention relates to the field of packaging bag production technology, and in particular to a synchronous unwinding and correction device. Background Technology

[0002] Packaging bags are bags used to package various goods, facilitating transportation and storage during production and distribution. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags end up in landfills like regular waste, with only 7% being recycled. Based on manufacturing processes, they are often categorized into plastic packaging bags and composite packaging bags.

[0003] The packaging process in a packaging production line includes major steps such as filling, wrapping, and sealing. Therefore, packaging machines are also divided into: filling machines, sealing machines, wrapping machines, multi-functional packaging machines, etc.; packaging production lines are also divided into: forming-filling-sealing packaging production lines, cartoning and boxing packaging production lines, liquid filling machines and their assembly lines, etc.

[0004] Existing packaging bag production lines use one or two or more materials to fold the bags, followed by bottom folding, heat pressing, and other processes to produce the bags. However, when using two or more materials, the materials are prone to displacement during the feeding process. When correcting the materials, the correction components cannot effectively correct the multiple materials simultaneously, resulting in poor correction performance and consequently, poor quality of the finished packaging bags. Summary of the Invention

[0005] This invention discloses a synchronous unwinding and correction device, which aims to solve the technical problem in existing packaging bag production lines in the background art. During production, one or more materials are used to fold the bags in half, and then the bags are produced through processes such as bottom folding and hot pressing. However, when two or more materials are used for production and processing, the materials are prone to displacement during the feeding process. However, when correcting the materials, the correction components are difficult to effectively correct the multiple materials simultaneously, resulting in poor correction effect and thus causing poor quality of finished packaging bags during production.

[0007] Equipped with an unwinding frame, support base, synchronous correction module, mounting base, stagnant feeding module, mounting plate, guide roller, transmission rod, transmission belt, linkage wheel, conveyor guide roller, overlapping roller, gear one, gear two, and drive motor, the synchronous correction module allows multiple materials to move simultaneously for correction, enabling rapid overlapping and correction of materials during packaging bag production. This ensures packaging bag quality, improves the device's efficiency, and meets the unwinding correction requirements. The stagnant feeding module facilitates material feeding by operators and, during unwinding, causes the air roller to stop, tightening the material and preventing over-feeding, thus meeting the device's feeding requirements. The drive motor, transmission belt, linkage wheel, gear one, gear two, conveyor guide roller, and overlapping roller provide initial overlapping conveying of the unwound packaging roll.

[0008] In a preferred embodiment, the synchronous correction module includes a correction frame, which is fixedly connected to the top of the support base.

A fixed support plate is fixedly connected to one side of the correction frame, and three electric rods are fixedly connected to the fixed support plate. The output ends of the three electric rods are respectively fixedly connected to the outer walls of the three movable blocks.

[0009] By incorporating a synchronous correction module, the device can simultaneously correct the deviation of multiple materials, thereby enhancing its effectiveness. During synchronous correction of multiple materials, the module can individually correct the position of each material, allowing them to quickly overlap and complete the correction process, thus increasing the device's correction efficiency. After correction, the synchronous correction module can clamp and convey the overlapping areas to prevent further deviation of the materials, ensuring the correction effect and ultimately improving the quality of the finished packaging bags.

[0010] In a preferred embodiment, the stagnant feeding module includes a power motor, which is fixedly connected to the inner wall of one side of the mounting base. The output shaft of the power motor is connected to a mounting rod via a coupling. One end of the mounting rod is movably connected to the inner wall of the other side of the mounting base. Three material bases are movably connected to the outer wall of the mounting rod. The outer walls of the three material bases are respectively provided with three interconnected locking slots on the outer wall of the mounting rod. Each of the three material bases is fixedly connected to an electric push rod. The output ends of the three electric push rods are fixedly connected to adjusting locking plates. The outer walls of the three adjusting locking plates are respectively in contact with the inner walls of the three locking slots. Each of the three material bases is fixedly connected to a motor, and the output shafts of the three motors are connected to transmission gears via couplings.

The outer walls of the three stabilizing plates contact the outer walls of the three stabilizing rings respectively.

[0011] By incorporating a pause-feeding module, the angle of the air rollers can be adjusted during operation, facilitating material feeding and increasing the ease of use. Furthermore, the device can adjust the number of air rollers based on the material quantity, enhancing its versatility. During material unwinding, the device can pause the rotating air rollers as needed, preventing over-unwinding and dragging, thus avoiding dust and other impurities adhering to the material and affecting finished product quality. The pause also allows the material to be taut to adjust tension, further enhancing the device's versatility.

[0012] In a preferred embodiment, the feeding and positioning module includes two electric telescopic rods, each fixedly connected to the top of one of the material bases. The output ends of the two electric telescopic rods are fixedly connected to the same adjusting assembly. One outer wall of the adjusting assembly has an opening, and the inner wall of the opening is fixedly connected to a magnetic suction element. Guide rings are fixedly connected to both outer walls of the adjusting assembly. Limiting rods are movably connected to the other two material bases. Positioning assemblies are fixedly connected to the tops of the two limiting rods. Gear rods are movably connected inside the two positioning assemblies.

One outer wall of each connecting iron block contacts the outer walls of both magnetic suction elements, and the outer walls of the two gear rods contact the inner walls of the two guide rings.

[0013] By incorporating a feeding and positioning module, the module can initially position the upper roller of the packaging roll during use, ensuring that multiple materials are initially in the same position when being fed, facilitating unwinding. Furthermore, when adjusting the feeding position, the feeding and positioning module can be connected to the adjustment kit via a gear lever, allowing the adjustment kits on multiple air rollers to be adjusted synchronously with the positioning kit, further improving the consistency of the upper roller position of the packaging roll and enhancing the effectiveness of the device.

[0014] As can be seen from the above, the synchronous unwinding and correction device provided by the present invention has the effect of improving the unwinding and correction effect. When performing correction operation, it can perform correction operation on multiple materials at the same time, which improves the use effect of the device. Moreover, the correction efficiency of the device can be increased through synchronous correction operation. When in use, it can quickly make multiple materials overlap and align to ensure the quality of the finished packaging bag. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] The synchronous unwinding and correction device disclosed in this invention is mainly used in situations where materials are prone to displacement during the production feeding process. However, when correcting the materials, the correction components are difficult to effectively correct multiple materials simultaneously, resulting in poor correction effect and thus causing poor quality of finished packaging bags during production.

[0028] Reference Figures 1-10The synchronous unwinding and correction device includes a base plate 1, an unwinding frame 2 fixedly connected to the top of the base plate 1, a mounting plate 10 fixedly connected to the inner walls of both sides of the unwinding frame 2, a support base 11 fixedly connected to the top of the mounting plate 10, a synchronous correction module 3 mounted on the top of the support base 11, a mounting base 9 fixedly connected to the unwinding frame 2, a stopping feeding module 8 mounted on the mounting base 9, three guide rollers 5 mounted on the top of the mounting plate 10, and four transmission rods 13 mounted on the top of the mounting plate 10.

The outer walls of each of the three transmission rods 13 are fixedly connected to linkage wheels 16. The outer walls of the three linkage wheels 16 are provided with the same transmission belt 15. The outer walls of two of the transmission rods 13 are fixedly connected to gear one 17 and gear two 18, respectively. Gear one 17 and gear two 18 mesh with each other. The bottom of the mounting plate base 10 is fixedly connected to a drive motor 14, and the output shaft of the drive motor 14 is connected to the bottom end of one of the transmission rods 13 through a coupling.

[0029] Specifically, during use, the synchronous correction module 3 can simultaneously correct the movement of multiple materials, thereby quickly overlapping and correcting the materials during the packaging bag production process to ensure the production quality of the packaging bags, improve the effectiveness of the device, and meet the unwinding correction requirements of the device; the stagnant feeding module 8 facilitates the feeding operation of materials by the staff, and at the same time, during unwinding, the stagnant feeding module 8 can cause the air roller 6 to stop, thereby tightening the material during use and avoiding over-feeding of the material during unwinding, thus meeting the material feeding requirements of the device; during use, the unwound packaging roll 7 can be initially overlapped and conveyed through the drive motor 14, transmission belt 15, linkage wheel 16, gear one 17, gear two 18, conveying guide roller 12 and overlapping roller 4.

[0030] Reference Figures 1-6In a preferred embodiment, the synchronous correction module 3 includes a correction frame 301, which is fixedly connected to the top of the support base 11. Three through correction openings 304 are provided on one outer wall of the correction frame 301. Correction guide frames 309 are fixedly connected to the inner walls of each of the three correction openings 304. Two guide rollers 302 are connected to each of the three correction guide frames 309 via bearings. The multiple guide rollers 302 are located on the outer sides of the correction frame 301. Two mounting frames 303 are fixedly connected to the inner walls of both sides of the correction frame 301. Two fixing rods 307 are fixedly connected to the outer walls of opposite sides of the two mounting frames 303. Two mounting support plates 308 are provided on the outer walls of the two fixing rods 307. Each of the three mounting ports 308 has three openings at its top, and an air pump 318 is slidably connected inside each of the mounting ports. Three motors 314 are fixedly connected to each of the two mounting frames 303. The output shafts of each motor 314 are connected to adjusting rollers 311 via couplings. Each adjusting roller 311 has a connecting cable 315, and one end of each connecting cable 315 is fixedly connected to a connector 317. The inner walls of each connector 317 are fixedly connected to the outer walls of each air pump 318. Three guide sleeves 316 are fixedly connected to each of the two mounting frames 303, and the connecting cables 315 are located inside each guide sleeve 316. Connecting pipes 320 are fixedly connected to the input ends of each air pump 318. Each input terminal of the 0 is fixedly connected to a negative pressure chamber 312. Multiple negative pressure chambers 312 are located inside three correction ports 304. The outer walls of each negative pressure chamber 312 are fixedly connected to an outer fitting plate 310. One side of the outer wall of each outer fitting plate 310 has a circular opening. Multiple fixed suction cups 313 are provided on the outer walls of each negative pressure chamber 312. The outer walls of the multiple fixed suction cups 313 contact the inner walls of the multiple circular openings. Three limiting guides 319 are fixedly connected to the bottom of each of the two mounting plates 308. The outer walls of multiple connecting pipes 320 contact the inner walls of the multiple limiting guides 319. Telescopic springs 321 are fixedly connected to the bottom of each negative pressure chamber 312. The bottom ends of the multiple telescopic springs 321 contact the bottoms of the three correction ports 304. Fixed connection; a fixed opening is provided on one side of the outer wall of the correction frame 301, and three movable openings are provided at the top of the fixed opening. Movable blocks 326 are slidably connected to the inner walls of the three movable opening rods. Movable rods 324 are connected to the top of the three movable blocks 326 through bearings. Three motors 325 are fixedly connected to the bottom of the fixed opening. The output shafts of the three motors 325 are connected to drive rods 323 through couplings. Conveying clamp rollers 322 are fixedly connected to the outer walls of the three drive rods 323 and the three movable rods 324. A fixed support plate 305 is fixedly connected to one side of the outer wall of the correction frame 301. Three electric rods 306 are fixedly connected to the fixed support plate 305. The output ends of the three electric rods 306 are fixedly connected to the outer walls of the three movable blocks 326 respectively.

[0031] Specifically, during the unwinding process, various materials enter the interiors of the three correction ports 304 via the guide rollers 302. At this time, the outer wall of the material contacts the correction guide frame 309 and the outer wall of the bonding outer plate 310. Then, the offset is detected by the detection equipment. When offset occurs, the air pump 318 is started. The air pump 318 draws air through the connecting pipe 320, thereby creating a negative pressure state inside the negative pressure chamber 312. This causes the fixing suction cup 313 to adsorb and fix the material. Then, the motor 314 is started, which drives the adjusting roller 311 to rotate. This causes the adjusting roller 311 to wind or unwind the connecting cable 315. During winding, the connecting cable 315 pulls the connecting piece 31. 7. This causes the air pump 318 to drive the connecting pipe 320 and the negative pressure chamber 312 to rise, thereby adjusting the material position for correction. When released, the telescopic spring 321 pulls the negative pressure chamber 312 down to adjust the material position for correction. After correction is completed, the second motor 325 and the electric rod 306 are started. The electric rod 306 drives multiple movable blocks 326 to move, which in turn drives the movable rod 324 to move. This causes multiple conveying clamping rollers 322 to clamp multiple materials respectively. At this time, the air pump 318 is turned off, the fixed suction cup 313 is separated from the material, and the second motor 325 drives multiple drive rods 323 to rotate and clamp and convey the material, preventing the material from shifting again after correction.

[0032] In specific application scenarios, the synchronous correction module 3 is suitable for the material unwinding and correction process. That is, when the synchronous correction module 3 is in use, it can simultaneously correct the deviation of multiple materials, thereby increasing the effectiveness of the device. When performing synchronous correction of multiple materials, the synchronous correction module 3 can correct the position of each material separately, so that the multiple materials can quickly overlap to complete the correction, thereby increasing the correction efficiency of the device. After correction, the synchronous correction module 3 can clamp and convey the overlapping parts to prevent the multiple materials from shifting again after correction, so as to ensure the correction effect and thus improve the quality of the finished product of the packaging bag production.

[0033] Reference Figure 1 , Figure 8 and Figure 9In a preferred embodiment, the stagnant feeding module 8 includes a power motor 816, which is fixedly connected to the inner wall of one side of the mounting base 9. The output shaft of the power motor 816 is connected to a mounting rod 815 via a coupling. One end of the mounting rod 815 is connected to the inner wall of the other side of the mounting base 9 via a bearing. Three material bases 807 are rotatably connected to the outer wall of the mounting rod 815. The outer walls of the three material bases 807 are respectively provided with three interconnected openings with the outer wall of the mounting rod 815. Each of the three material bases 807 has a locking slot 814, and each of the three material bases 807 is fixedly connected to an electric push rod 805. The output ends of each of the three electric push rods 805 are fixedly connected to an adjusting locking plate 806. The outer walls of the three adjusting locking plates 806 are in contact with the inner walls of the three locking slots 814. Each of the three material bases 807 is fixedly connected to a motor 810. The output shafts of each of the three motors 810 are connected to a transmission gear 811 via a coupling. The tops of each of the three material bases 807 are connected to a shaft seat 81 via bearings. 3. Driven gears 812 are fixedly connected to the outer walls of each of the three shaft seats 813. Each driven gear 812 meshes with a transmission gear 811. A retaining ring 804 is fixedly connected to the inner wall of each of the three shaft seats 813. A mounting base 801 is connected to each of the three shaft seats 813 via bearings. An elastic retaining ring 803 is fixedly connected to the outer wall of each of the three mounting bases 801. Each elastic retaining ring 803 engages with a retaining ring 804. A [missing information - likely a type of retaining ring] is fixedly connected to the top of each of the three mounting bases 801. Air-expanding rollers 6, with feeding and positioning modules 19 on the outer walls of the three air-expanding rollers 6, and packaging rolls 7 on the outer walls of the three air-expanding rollers 6; two hydraulic rods 808 are fixedly connected to each of the three material bases 807, and the output ends of the two hydraulic rods 808 on the same material base 807 are fixedly connected to the same stagnation plate 809, and stagnation rings 802 are fixedly connected to the outer walls of the three mounting bases 801, with the outer walls of the three stagnation plates 809 in contact with the outer walls of the three stagnation rings 802 respectively.

[0034] Specifically, in use, the electric push rod 805 is activated, causing it to lift the adjusting locking plate 806. This causes the adjusting locking plate 806 to separate from the mounting base 9 and engage with the locking slot 814, thus fixing the material base 807 and the mounting rod 815 in a relatively fixed position. When no material is being loaded, the adjusting locking plate 806 on the material base 807 separates from the locking slot 814 and engages with one outer wall of the mounting base 9. This fixes the material base 807 when the mounting rod 815 rotates, allowing for individual control of the material base 807. Then, the power motor 816 drives the mounting rod 815 to rotate, adjusting the angle between the material base 807 and the air roller 6 until loading and unwinding are complete. When the motor 810 is started, it drives the transmission gear 811 to rotate. Since the transmission gear 811 meshes with the driven gear 812, the motor 810 drives the shaft seat 813 to rotate. Since the elastic retaining ring 803 is engaged with the fixed retaining ring 804, the shaft seat 813 drives the mounting base 801 and the air roller 6 to rotate and release the material. At this time, the hydraulic rod 808 is activated as needed. The hydraulic rod 808 drives the stop plate 809 to contact the stop ring 802, thereby stopping the rotation of the mounting base 801 and causing the elastic retaining ring 803 to elastically deform. Then the stop plate 809 separates from the stop ring 802, and the elastic retaining ring 803 engages with the fixed retaining ring 804 again to continue unwinding.

[0035] In specific application scenarios, the pause feeding module 8 is suitable for the material loading and unwinding processes. When in use, the pause feeding module 8 can adjust the angle of the air expansion roller 6, making it easier for workers to load materials and increasing the convenience of the device. During loading, the device can adjust the number of air expansion rollers 6 according to the amount of material, increasing the versatility of the device. When unwinding materials, the device can pause the rotating air expansion roller 6 as needed, thereby preventing the material from being over-unwound and dragging, and preventing dust and other impurities from adhering to the material and affecting the quality of the finished product. Furthermore, the pause can tighten the material to adjust the tension, further improving the versatility of the device.

[0036] Reference Figure 8 and Figure 10In a preferred embodiment, the feeding and positioning module 19 includes two electric telescopic rods 1909, both of which are fixedly connected to the top of one of the material bases 807. The output ends of the two electric telescopic rods 1909 are fixedly connected to the same adjusting kit 1904. One outer wall of the adjusting kit 1904 has an opening, and the inner wall of the opening is fixedly connected to a magnetic suction element 1903. Guide collars 1910 are fixedly connected to both outer walls of the adjusting kit 1904. Limiting rods 1905 are slidably connected to the other two material bases 807. The top ends of the two limiting rods 1905 are fixedly connected to positioning kits 1904. 901, gear rods 1908 are slidably connected inside the two positioning kits 1901, and stepper motors 1907 are fixedly connected to the top of the two positioning kits 1901. The output shafts of the two stepper motors 1907 are connected to drive gears 1906 through couplings. The two drive gears 1906 mesh with the two gear rods 1908 respectively, and connecting iron blocks 1902 are fixedly connected to one end of the two gear rods 1908. The outer wall of one side of the two connecting iron blocks 1902 contacts the outer walls of both sides of the magnetic suction component 1903 respectively. The outer walls of the two gear rods 1908 are in contact with the inner walls of the two guide rings 1910 respectively.

[0037] Specifically, before feeding, the electric telescopic rod 1909 is activated, which drives the adjustment kit 1904 to move, thereby adjusting the position of the upper roller of the packaging roll 7. At the same time, during the adjustment, the device can activate the stepper motor 1907 as needed. The stepper motor 1907 drives the drive gear 1906 to rotate. Since the drive gear 1906 meshes with the gear rod 1908, the drive motor 14 can drive the gear rod 1908 to move, which in turn drives the connecting iron block 1902 to move until the gear rod 1908 moves into the guide collar 1910, so that the connecting iron block 1902 is connected to the magnetic suction component 1903. This allows the electric telescopic rod 1909 to drive the adjustment kit 1904 and the positioning kit 1901 to adjust synchronously.

[0038] In specific application scenarios, the feeding and positioning module 19 is suitable for the material feeding roller stage. That is, when the feeding and positioning module 19 is in use, it can perform preliminary positioning of the upper roller position of the packaging roll 7, thereby ensuring that it is initially in the same position when feeding multiple materials, which facilitates unwinding. When adjusting the feeding position, the feeding and positioning module 19 can be connected to the positioning kit 1901 and the adjustment kit 1904 through the gear rod 1908, so that the positions of the adjustment kit 1904 and the positioning kit 1901 on multiple air expansion rollers 6 are adjusted synchronously, further improving the consistency of the upper roller position of the packaging roll 7 and increasing the effectiveness of the device.

[0039] Working principle: During use, the electric push rod 805 is activated, causing it to lift the adjusting locking plate 806. This causes the adjusting locking plate 806 to separate from the mounting base 9 and engage with the locking slot 814, thus fixing the material base 807 and the mounting rod 815 in a relatively fixed position. When no material is being loaded, the adjusting locking plate 806 on the material base 807 separates from the locking slot 814 and engages with one outer wall of the mounting base 9. This ensures that the material base 807 is fixed when the mounting rod 815 rotates, allowing for individual control of the material base 807. Then, the power motor 816 drives the mounting rod 815 to rotate, thereby adjusting the angle between the material base 807 and the air roller 6. Before feeding, the electric telescopic rod 1909 is activated, which drives the adjustment kit 1904 to move, thereby adjusting the position of the upper roller of the packaging roll 7. At the same time, during adjustment, the device can activate the stepper motor 1907 as needed. The stepper motor 1907 drives the drive gear 1906 to rotate. Since the drive gear 1906 meshes with the gear rod 1908, the drive motor 14 can drive... The moving gear rod 1908 moves, which in turn drives the connecting iron block 1902 to move until the gear rod 1908 moves into the guide collar 1910, causing the connecting iron block 1902 to connect with the magnetic suction component 1903. This causes the electric telescopic rod 1909 to drive the adjusting kit 1904 and the positioning kit 1901 to adjust synchronously until the feeding is completed. During unwinding, the motor 810 is started, which drives the transmission gear 811 to rotate. Since the transmission gear 811 meshes with the driven gear 812, ... The motor 810 drives the shaft seat 813 to rotate. Because the elastic retaining ring 803 is engaged with the fixed retaining ring 804, the shaft seat 813 drives the mounting base 801 and the air roller 6 to rotate and release material. At this time, the hydraulic rod 808 is activated as needed. The hydraulic rod 808 drives the stop plate 809 to contact the stop ring 802, thereby stopping the rotation of the mounting base 801 and causing the elastic retaining ring 803 to elastically deform. Then the stop plate 809 separates from the stop ring 802, and the elastic retaining ring 803 is engaged with the fixed retaining ring 804 again to continue unwinding.During the unwinding process, various materials enter the interiors of the three correction ports 304 via the guide rollers 302. At this time, the outer wall of the material is in contact with the correction guide frame 309 and the outer wall of the bonding outer plate 310. Then, the deviation is detected by the detection equipment. If deviation occurs, the air pump 318 is started. The air pump 318 draws air through the connecting pipe 320, thereby creating a negative pressure state inside the negative pressure chamber 312. This causes the fixing suction cup 313 to adsorb and fix the material. Then, the motor 314 is started, which drives the adjusting roller 311 to rotate. This causes the adjusting roller 311 to wind or unwind the connecting cable 315. During winding, the connecting cable 315 pulls the connecting piece 317. This causes the air pump 318 to lift the connecting pipe 320 and the negative pressure chamber 312 to adjust the material position for correction. When released, the telescopic spring 321 pulls the negative pressure chamber 312 down to adjust the material position for correction. After correction, the second motor 325 and the electric lever 306 are started. The electric lever 306 drives multiple movable blocks 326 to move, which in turn drives the movable rod 324 to move. This causes multiple conveying rollers 322 to clamp various materials. At this time, the air pump 318 is turned off, the fixed suction cup 313 separates from the material, and the second motor 325 drives multiple drive rods 323 to rotate and clamp and convey the material, preventing the material from shifting again after correction.
