Description
Technical Field
[0001] The present invention relates to the technical field of packaging bag related equipment, in particular to a packaging bag printing device with a deviation correction function and a deviation correction method. Background Art
[0002] Packaging bags are bags used to pack various items, making it easy to transport and store goods during production and circulation. They are widely used in daily life and industrial production.
[0003] For example, an automatically adjustable deviation correction device for packaging bag printing with announcement number CN214652435U is fixed by fitting the two ends of the reel with a fixed cone head and a movable cone head, and pushing the card block into the clearance hole through a compression spring, so that the reel rotates synchronously with the assembly block. The installation is convenient, and the assembly block is driven to rotate by a winding motor to allow the reel to rewind the packaging bag. At the same time, a printing device is used to print a pattern, and a photoelectric sensor is used to sense the position of the front and rear ends of the packaging bag relative to the printing device. When the packaging bag deviates and blocks the photoelectric sensor on one side, the photoelectric sensor transmits a signal to the PLC controller, and the PLC controller controls the forward and reverse rotation of the deviation correction motor, so that the nut seat moves longitudinally along the limit groove, and the position of the unwinding rack can be adjusted. The position of the packaging bag returns to normal, achieving a good correction effect, which is beneficial to ensuring printing quality. However, in actual use, when the packaging bag roll is unwinding, the weight of the substrate may be reduced due to the reduction in the roll diameter, which may affect the distribution and stability of the tension, thereby causing the roll to loosen. When the friction coefficient between the inner and outer surfaces of the roll is low or uneven, it will also affect its stability during transportation. A low friction coefficient will cause the roll to slide easily when subjected to external force, and may also cause the roll to loosen. Although the roll can be corrected after it is loose, the number of corrections will increase, the service life of the correction structure is limited, and continuous correction is also likely to affect the printing accuracy of the packaging bag. There are certain usage defects.
[0004] Therefore, we propose a packaging bag printing device with a deviation correction function and a deviation correction method to solve the above-mentioned problems. Summary of the invention

The low friction coefficient will cause the roll to slide easily when subjected to external force, and may also cause the roll to loosen. Although the roll can be corrected after it is loosened, the number of corrections will increase, the service life of the correction structure is limited, and continuous correction will easily affect the printing accuracy of the packaging bag.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the packaging bag printing device and the correction method with the correction function are provided with a correction component on the top side of the base, so that the packaging bag can be corrected during the printing process, and the tensioning wheel can be driven to rise as the correction proceeds during the correction process, so as to tension the conveying of the packaging bag, thereby preventing the roll from becoming loose during the unwinding process, avoiding frequent adjustment of the packaging bag position due to the looseness, and avoiding affecting the printing accuracy of the packaging bag;
[0026] 1. A deviation correction component is set on one side of the top of the base. When printing the packaging bag, the bag reel is sleeved on the outside of the rotating shaft so that one end of the reel fits with the first conical block, and then the second conical block is screwed on to limit the reel. During the unwinding process, the reel is connected to the vertical plate through the damping bearing, and the reel will not loosen easily. One end of the reel is passed around the top of the tension wheel and between the two sets of rotating rollers, and reeled through the reel shaft. The drive motor is started to reel the packaging bag, and the hydraulic push rod is started to drive the movable plate to descend. The movable plate drives the guide rod to move forward while descending. The printing mechanism prints the packaging bag, and the air-drying mechanism air-dries the packaging bag. The position of the packaging bag is detected by two photoelectric sensors, and the deviation of the packaging bag can be monitored. After the deviation occurs, the electric push rod on the vertical plate drives the L-shaped plate to move. While the L-shaped plate moves, it drives the positioning sleeve to slide on the support rod to limit the position, so that the packaging bag can be corrected. When the L-shaped plate moves backward while correcting the packaging bag, if the front movable sleeve moves outside the fixed rod, the two rubber blocks are tightly attached to the fixed rod under the action of the torsion spring, so that the L-shaped plate If the movement drives the front fixed rod to move, the front movable sleeve can be driven to move backward. During the movement of the rear fixed rod, the opening of the two rubber blocks will not drive the rear movable sleeve to move. When the L-shaped plate is placed and moved forward, the rear movable sleeve will be driven to move but the front movable sleeve will not be driven to move. No matter how the L-shaped plate moves, the movable rod can be driven to rotate, so that the moving rod can be pushed to move. During the movement of the moving rod, the limiting sleeve can be driven to slide outside the mounting rod to limit the movement of the moving rod. After the moving rod moves, the push rod can be driven to rotate, so that the push rod The cylinder is rotated to slide inside the sleeve, so that the vertical rod can be lifted, and the conveyed packaging bag can be tensioned by the tensioning wheel, and the vertical rod can slide inside the cylinder to compress the telescopic spring to avoid excessive tension force affecting the conveying of the bag. The packaging bag can be corrected during the printing process through the correction component, and the tensioning wheel can be driven to rise as the correction progresses, so as to tension the conveying of the packaging bag, so as to avoid the roll from becoming loose during the unwinding process, avoid frequent adjustment of the packaging bag position due to looseness, and avoid affecting the printing accuracy of the packaging bag;
[0027] 2. When the push rod pushes the cylinder to move, the positioning groove on one side of the cylinder can lift the positioning rod to move, so that the positioning rod slides on the positioning block to compress the reset spring, so that the positioning rod can be retracted when the cylinder rises. After the cylinder rises, when the other positioning groove is aligned with the positioning rod, the reset spring can restore the deformation, so that the positioning rod can be engaged with the positioning groove to prevent the cylinder from falling, so that the cylinder can be prevented from falling while the packaging bag is being tensioned, and the cylinder reset can be prevented from affecting the tensioning effect of the packaging bag;
[0028] 3. The connecting seat is driven by a driving motor to rotate on the mounting plate, so that the winding shaft can be driven to rotate and the printed packaging bag can be wound up. After the packaging bag is wound up, the two movable plates can be moved to make the movable plates approach each other to compress the compression spring, thereby driving the limit plate to move, so that the limit plate is disengaged from the limit groove, so that the positioning plate loses its limit, and the rubber pad on the positioning plate no longer fits the winding shaft. The positioning plate can be removed, and then the winding shaft can be removed, so that the roll after winding can be removed conveniently, thereby improving the convenience of use.

After the packaging bag is wound up, the two movable plates 308 can be moved so that the movable plates 308 are close to each other to compress the compression spring 310, thereby driving the limit plate 311 to move, so that the limit plate 311 is disengaged from the limit groove 312, so that the positioning plate 306 loses its limit, and the rubber pad on the positioning plate 306 no longer fits the winding shaft 304. The positioning plate 306 can be removed, and then the winding shaft 304 can be removed, so that the roll after winding can be removed conveniently, thereby improving the convenience of use.
[0057] Working principle: When using this packaging bag printing device with deviation correction function, first, according to Figure 1-Figure 10As shown, the bag transfer roll is sleeved on the outside of the rotating shaft 202, so that one end of the roll is in contact with the first conical block 203, and then the second conical block 204 is screwed on to limit the roll, and one end of the roll is passed around the top of the tensioning wheel 225 and between the two sets of rotating rollers 111, and is reeled through the reel shaft 304, and the driving motor 303 is started to reel the packaging bag, and the hydraulic push rod 103 is started to drive the movable plate 102 to descend, and the movable plate 102 drives the guide rod 104 to move and limit the position while descending, so that the printing mechanism 105 prints the packaging bag, and then the printing mechanism 105 prints the packaging bag. The air-drying mechanism 107 is used to air-dry the packaging bag. The position of the packaging bag is detected by two photoelectric sensors 106. The deviation of the packaging bag can be monitored. After the deviation occurs, the electric push rod 206 on the vertical plate 205 drives the L-shaped plate 201 to move. When the L-shaped plate 201 moves, it drives the positioning sleeve 209 to slide on the support rod 208 to limit the position, so that the packaging bag can be corrected. When the L-shaped plate 201 moves backward while correcting the deviation of the packaging bag, if the front movable sleeve 212 moves outside the fixed rod 211, due to the two rubber blocks 2123 on the torsion spring 2 When the L-shaped plate 201 moves forward, the movable sleeve 212 at the rear side will not be moved due to the opening of the two rubber blocks 2123. When the L-shaped plate 201 moves forward, the movable sleeve 212 at the rear side will not be moved, and no matter how the L-shaped plate 201 moves, the movable sleeve 213 can be driven to rotate, so that the movable sleeve 214 can be pushed to move. During the movement, the moving rod 214 can drive the limiting sleeve 217 to slide outside the mounting rod 216 to limit the movement of the moving rod 214. After the moving rod 214 moves, it can push the push rod 222 to rotate, so that the push rod 222 rotates to push the cylinder 219 to slide inside the sleeve 218, so that the vertical rod 223 can be lifted, and the conveyed packaging bag can be tensioned by the tensioning wheel 225. When the push rod 222 pushes the cylinder 219 to move, the positioning groove 226 on one side of the cylinder 219 can push up the positioning rod 228 to move, so that the positioning rod 228 The return spring 229 is slidably compressed on the positioning block 227, so that the positioning rod 228 can be retracted when the cylinder 219 rises. After the cylinder 219 rises, when the other positioning groove 226 is aligned with the positioning rod 228, the return spring 229 can restore its deformation, so that the positioning rod 228 can be engaged with the positioning groove 226 to prevent the cylinder 219 from falling. After the packaging bag is rolled up, the two moving plates 308 can be moved so that the moving plates 308 are close to each other to compress the compression spring 310, thereby driving the limit plate 311 to move, so that the limit plate 311 is separated from the limit groove 312, so that the positioning plate 306 loses its limit, so that the rubber pad on the positioning plate 306 no longer fits the winding shaft 304, and the positioning plate 306 can be removed.Then the reel 304 can be removed.

4. A method for correcting a packaging bag printing device with a correcting function, using the packaging bag printing device with a correcting function as claimed in claim 3, and using the following steps: Step 1: When printing the packaging bag, the bag roll is sleeved on the outside of the rotating shaft (202) so that one end of the roll is in contact with the first conical block (203), and then the second conical block (204) is screwed on to limit the roll, and one end of the roll is passed around the top of the tensioning wheel (225) and between the two sets of rotating rollers (111), and is rolled up by the reeling shaft (304), and the driving motor (303) is started to roll up the packaging bag, and the hydraulic push rod (103) is started to drive the movable plate (102) to descend, and the movable plate (102) drives the guide rod (104) to move and limit the position while descending, so that the printing mechanism (105) prints the packaging bag, and the air-drying mechanism (107) is used to air-dry the bag, and the packaging bag is then air-dried. The position of the packaging bag is detected by two photoelectric sensors (106). The deviation of the packaging bag can be monitored. After the deviation occurs, the electric push rod (206) on the vertical plate (205) drives the L-shaped plate (201) to move. When the L-shaped plate (201) moves, it drives the positioning sleeve (209) to slide on the support rod (208) to limit the position, so that the packaging bag is corrected. When the L-shaped plate (201) moves backward while correcting the deviation of the packaging bag, the front movable sleeve (212) moves outside the fixed rod (211). Because the two rubber blocks (2123) are tightly attached to the fixed rod (211) under the action of the torsion spring (2124), the L-shaped plate (201) moves and drives the front fixed rod (211) to move. 1) The movement drives the front movable sleeve (212) to move backward. During the movement of the rear fixed rod (211), the opening of the two rubber blocks (2123) does not drive the rear movable sleeve (212) to move. When the L-shaped plate (201) is placed forward, the rear movable sleeve (212) is driven to move, but the front movable sleeve (212) is not driven to move. Regardless of how the L-shaped plate (201) moves, the movable rod (213) is driven to rotate, so that the moving rod (214) is pushed to move. During the movement of the moving rod (214), the limiting sleeve (217) is driven to slide outside the mounting rod (216) to limit the movement of the moving rod (214). After the moving rod (214) moves, the pushing rod (214) is pushed. The rod (222) rotates, so that the push rod (222) rotates to push the cylinder (219) to slide inside the sleeve (218), lift the vertical rod (223), and tension the transported packaging bag through the tensioning wheel (225), and the vertical rod (223) slides inside the cylinder (219) to compress the telescopic spring (224), so as to avoid excessive tensioning force affecting the transport of the package transfer bag, and the packaging bag is corrected during the printing process through the correction component (2), and during the correction process, the tensioning wheel (225) is driven to rise, thereby tensioning the transport of the packaging bag, so as to avoid the roll being loosened during the unwinding process, avoid frequent adjustment of the packaging bag position due to looseness, and avoid affecting the printing accuracy of the packaging bag; Step 2: When the push rod (222) pushes the cylinder (219) to move, the positioning groove (226) on one side of the cylinder (219) pushes up the positioning rod (228) to move, so that the positioning rod (228) slides on the positioning block (227) to compress the return spring (229), so that when the cylinder (219) rises, the positioning rod (228) retracts. After the cylinder (219) rises, when the other positioning groove (226) is aligned with the positioning rod (228), the return spring (229) recovers its deformation, so that the positioning rod (228) is engaged with the positioning groove (226), so as to prevent the cylinder (219) from descending, so as to prevent the cylinder (219) from descending while the packaging bag is being tensioned, and to prevent the cylinder (219) from resetting and affecting the tensioning effect of the packaging bag; Step 3: The connecting seat (302) is driven to rotate on the mounting plate (301) by a driving motor (303), thereby driving the reeling shaft (304) to rotate and reel in the printed packaging bag. After the packaging bag is reeled in, the two movable plates (308) are moved so that the movable plates (308) are brought close to each other to compress the compression spring (310), thereby driving the limiting plate (311) to move, so that the limiting plate (311) is disengaged from the limiting groove (312), so that the positioning plate (306) loses its limit, so that the rubber pad on the positioning plate (306) no longer fits the reeling shaft (304), and the positioning plate (306) is removed, and then the reeling shaft (304) is removed, so that the reel after reeling is conveniently removed, thereby improving the convenience of use.
