Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to an automatic bag-making and feeding system for a digital printing machine. Background Technology

[0002] The automatic bag-forming and feeding system for digital printing machines is an automated device used to improve the production efficiency of digital printing. After external equipment folds, cuts, and glues printed paper or materials into bags, the automatic bag-forming and feeding system automatically transports these bags to subsequent packaging or processing stages. During bag transport, the system can dry the formed bags, allowing the adhesive to fully cure in a short time, thereby increasing the bag's strength. (Price: Authorization Publication No. CN 222006802) U's patent discloses a printed product conveying device, including a crossbeam and a printed product drying channel. Support legs are fixedly installed at the bottom of the crossbeam, a conveyor belt is installed between the two crossbeams, a controller is installed on the front side of the crossbeam, and connecting seats and reinforcing fork seats are provided on both sides of the printed product drying channel. Two first fans are installed on the upper side inside the printed product drying channel. During the use of this equipment, although multiple sets of fans can be set to dry the printed products, thereby increasing the contact time between the hot air and the printed products, each fan requires a certain amount of electricity. The simultaneous operation of multiple sets of fans will significantly increase the energy consumption of the equipment, and the cost of setting up multiple sets of fans is also relatively high. Therefore, we propose an automatic bag feeding system for digital printing machines. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an automatic bag feeding system for digital printing machines. By driving two sets of air boxes to perform lateral reciprocating motion, it ensures that the printed bags can be dried evenly.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: an automatic bag feeding system for a digital printing machine, including a conveyor frame 1, a heat insulation cover 3 is provided in the middle of the upper end of the conveyor frame 1, an installation cover 4 is provided on the left side inside the heat insulation cover 3, and a drying mechanism 5 is also included.

[0021] Drying mechanism 5: It includes a crossbar 51, a fixed base 52, an air supply box 53, a connecting seat 57, and a drive assembly 59. The crossbars 51 are slidably connected to the sliding grooves opened on the front and rear sides of the right wall of the mounting cover 4. The right ends of both crossbars 51 are fixedly connected to the left ends of the fixed base 52. The left side of the fixed base 52 is provided with a connecting seat 57. The middle of the lower end of both the fixed base 52 and the connecting seat 57 is provided with an air supply box 53. The drive assembly 59 is located inside the mounting cover 4. The crossbars 51 are driven by the drive assembly 59. The drying mechanism 5 also includes guide slides 56 and springs 58. The guide slides 56 are slidably connected to the guide slide holes opened in the middle of the right wall of the mounting cover 4. The right ends of both guide slides 56 are fixedly connected to the connecting seat 57 on the left side. Springs 58 are respectively installed between the left end and the right end of the mounting cover 4. The springs 58 are all sleeved on the outside of the right side of the guide slide column 56. The guide slide column 56 is installed in conjunction with the drive assembly 59. The drying mechanism 5 also includes a fan 54 and an electric heating wire 55. The fan 54 is respectively installed on the upper side inside the air supply box 53. The electric heating wire 55 is installed on the lower side inside the air supply box 53. Ventilation openings are provided on the upper side of the left and right walls of the air supply box 53. Air supply outlets are provided at the lower end of the air supply box 53. The two fans 54 are respectively located below the vertically adjacent ventilation openings. The input ends of the fans 54 and the electric heating wire 55 are electrically connected to the output ends of the control switch group 2. The drive assembly 59 includes a fixing plate 591, a connecting plate 592, a mounting rod 593, and a transmission plate 594. The system includes an adjusting seat 595, a drive plate 596, a motor 597, a half-gear 598, and a gear 599. A mounting rod 593 is rotatably connected to the middle of the bottom wall of the mounting cover 4. A transmission plate 594 is located on the lower side of the outer arc surface of the mounting rod 593. The left ends of the two crossbars 51 are fixedly connected to the right ends of the fixed plate 591. The left ends of the two guide pins 56 are fixedly connected to the right ends of the connecting plate 592. Adjusting seats 595 are located in the middle of the right end of the fixed plate 591 and the middle of the left end of the connecting plate 592. Drive plates 596 are rotatably connected inside both adjusting seats 595. The upper ends of both drive plates 596 are rotatably connected to the lower ends of the transmission plate 594. A motor 597 is located on the left side of the upper end of the heat insulation cover 3. The lower end of the output shaft of the motor 597 is... A half-gear 598 is provided, and a gear 599 is provided on the upper side of the outer arc surface of the mounting rod 593. The half-gear 598 and gear 599 are installed together. The input end of the motor 597 is electrically connected to the output end of the control switch group 2. By controlling the control switch group 2, the motor 597 starts to run. During the rotation of the motor 597, it drives the half-gear 598 to rotate through the output shaft. When the half-gear 598 and gear 599 are engaged, gear 599 drives the transmission plate 594 to rotate through the mounting rod 593. During the rotation of the transmission plate 594, it provides a thrust to the adjusting seat 595 through the drive plate 596, thereby causing the left adjusting seat 595 to drive the crossbar 51 to move to the left through the fixing plate 591.The crossbar 51 moves the right-side air box 53 to the left via the fixed seat 52. Simultaneously, the right-side adjusting seat 595 moves the guide slide column 56 to the right via the connecting plate 592. This lateral reciprocating motion of the two air boxes 53 ensures that the printed bags are evenly dried, reducing the number of fans 54 required and lowering costs. It also increases the contact time between the hot air and the bag, ensuring the adhesive cures completely in a short time, thereby enhancing the bag's strength.

[0022] Among them, the front end of the conveyor frame 1 is equipped with a control switch group 2. The input end of the control switch group 2 is electrically connected to an external power supply, which can regulate the electrical components inside the equipment.

[0023] The conveyor frame 1 has conveyor rollers 7 rotatably connected to both the left and right sides. The two conveyor rollers 7 are connected by a conveyor belt. A conveyor motor 8 is set on the left side of the front end of the conveyor frame 1. The rear end of the output shaft of the conveyor motor 8 is fixedly connected to the front end of the left conveyor roller 7. The input end of the conveyor motor 8 is electrically connected to the output end of the control switch group 2. The external conveying equipment places the printed bag on the left side of the upper end of the conveyor belt. Then, through the control of the control switch group 2, the conveyor motor 8 starts to run. The output shaft of the conveyor motor 8 drives the left conveyor roller 7 to rotate. The left conveyor roller 7 drives the right conveyor roller 7 to rotate through the conveyor belt, thereby moving the printed bag to the right.

[0024] Among them, the air inlet on the right side of the upper end of the heat insulation cover 3 is equipped with a filter screen 6. When the fan 57 is running, it will generate suction, and the outside air will enter the interior of the heat insulation cover 3 after being filtered by the filter screen 6.

[0025] The working principle of the automatic bag-making and feeding system for a digital printing machine provided by this utility model is as follows: During the use of the automatic bag-making and feeding system for a digital printing machine, the external conveying equipment places the printed bags on the left side of the upper end of the conveyor belt. Then, through the control switch group 2, the conveyor motor 8 starts running. The output shaft of the conveyor motor 8 drives the left conveyor roller 7 to rotate. The left conveyor roller 7 drives the right conveyor roller 7 to rotate through the conveyor belt, thereby moving the printed bags to the right. When the printed bags move into the installation cover 3, through the control switch group 2, the fan 57 and the electric heating wire 55 start running. During the operation of the fan 57, suction is generated, and external air passes through the filter screen. After filtration, the air from the filter 6 enters the interior of the heat insulation cover 3. The filtered air then enters the air supply box 53 through the vent, where it is heated by an electric heating wire 10 (made of tungsten metal, which has high resistivity and effectively converts electrical energy into heat). The heated air is then exhausted through the air supply vent, blowing hot air onto the printed bags to dry them. Since the printed bags are made of multiple folded sheets of paper or materials bonded together, drying them ensures the adhesive cures completely in a short time, thus enhancing the bag's strength. During the operation of the fan 54, the electric... When motor 597 starts running, its rotation drives the half-gear 598 to rotate via its output shaft. When the half-gear 598 meshes with gear 599, gear 599 drives the transmission plate 594 to rotate via mounting rod 593. During rotation, the transmission plate 594 provides a thrust to the adjusting seat 595 via drive plate 596, causing the left adjusting seat 595 to move the crossbar 51 to the left via fixing plate 591. The crossbar 51 then drives the right air box 53 to the left via fixing seat 52. Simultaneously, the right adjusting seat 595 drives the guide slide column 56 to the right via connecting plate 592. Spring 58 extends, and the guide slide column 56 moves to the right via connecting seat 57. The left air supply box 53 is moved to the right. When the half-gear 598 separates from the gear 599, the tension generated by the contraction of the spring 58 can move the left air supply box 53 to the left to reset. The left air supply box 53 will drive the connecting plate 592 to the left to reset via the guide slide 56. The connecting plate 592 will drive the right adjusting seat 595 to the left to reset. During the movement of the adjusting seat 595, the adjusting seat 595 will push the transmission plate 594 through the right drive plate 596, thereby causing the transmission plate 594 to rotate around the mounting rod 593. During the rotation of the transmission plate 594, the transmission plate 594 will pull the left adjusting seat 595 to the right through the left drive plate 596.This causes the left-side adjusting seat 595, along with the fixing plate 591, to move to the right and reset. The fixing plate 591, via the crossbar 51, drives the fixing seat 52 to move to the right and reset. The fixing seat 52 then drives the right-side air supply box 53 to move to the right and reset, thereby causing the two sets of air supply boxes 53 to perform a lateral reciprocating motion. During the bag drying process, the conveyor belt continuously carries the printed bags to the right, finally causing the dried bags to leave the heat insulation cover 3. Then, the conveyor belt automatically transports the dried bags to subsequent packaging or processing stages.

[0026] It is worth noting that the motor 597 disclosed in the above embodiments can be 5IK200A-AF, the fan 54 can be ME92252V1-000C-A99, the conveyor motor 8 can be ECMA-C20604RS, and the control switch group 2 is equipped with control buttons corresponding to the fan 54, the electric heating wire 55, the motor 597 and the conveyor motor 8 for controlling their switching.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
