Description

Technical Field

[0001] The utility model relates to a die-cutting machine, in particular to a bag body base material gluing mechanism of a bag-making machine. Background Art

[0002] The bag making machine is a kind of equipment specially used for the automated production of packaging bags. In the production process of packaging bags, the bag base material needs to be glued for the subsequent bonding and molding operations. The traditional bag making machine uses a dispensing mechanism to glue the base material. This gluing method uses ordinary liquid glue commonly found on the market. This glue needs a certain amount of time to wait until the glue dries after gluing and bonding, resulting in low overall production efficiency of the equipment; in addition, the position of the base material may shift during the unwinding process, resulting in the inability of the gluing mechanism to accurately perform the gluing operation, affecting the subsequent bonding operation. Utility Model Content

[0006] Limit sensors that can sense the movable seat are arranged at both ends close to the first adjusting screw, and the limit sensors can control the driving motor to stop.

[0009] The movable seat comprises seat bodies arranged at two ends, and the two seat bodies are connected by a support shaft, and the support shaft rotatably supports the adjusting roller.

[0010] The above technical solution is a bag base material gluing mechanism of a bag making machine, which uses hot melt adhesive to gluing the base material.

[0015] As shown in the figure, the present utility model discloses a bag body substrate gluing mechanism of a bag making machine, comprising a feed winding roller 2, an adjusting roller 3 is arranged on one side corresponding to the feed winding roller 2, and the adjusting roller 3 is rotatably arranged on a movable seat, specifically, the movable seat comprises a seat body 8 arranged at both ends, the two seat bodies 8 are connected by a support shaft 6, and the support shaft 6 rotatably supports the adjusting roller 3. One end of the movable seat is screwed to the first adjusting screw 9, and the other end is screwed to the second adjusting screw 13, and the first and second adjusting screws are connected to the driving motor 10 in a transmission connection, specifically, a worm is connected to the output shaft of the driving motor 10, the worm is meshed with the worm wheel, the worm wheel is connected to the transmission shaft 12, the transmission shaft 12 is connected with a first helical gear and a second helical gear, the first helical gear is meshed with the third helical gear, the third helical gear is connected to the first adjusting screw 9, the second helical gear is meshed with the fourth helical gear, and the fourth helical gear is connected to the second adjusting screw 13. In addition, one end of the transmission shaft 12 is connected to a code disc assembly 11, which can transmit the rotation angle data of the transmission shaft 12 to the controller, thereby realizing accurate feedback of the number of screw rotations, so that the controller can more finely control the number of rotations required for the drive motor to drive the screw. A winding roller group 4 is arranged on one side of the discharge end of the adjusting roller 3, and a hot melt adhesive spray head 5 is arranged corresponding to the winding roller group 4. A color mark sensor is arranged on the frame, and the sensor can sense the color mark on the bag substrate 1. The color mark sensor can be set at any position on the frame, as long as it can be aligned with the color mark on the bag substrate 1 after passing through the adjusting roller 3. The color mark sensor can feedback information to the controller, and the controller can control the drive motor 10 to move. Furthermore, both ends of the first adjusting screw 9 are provided with limit sensors 7 that can sense the movable seat. The limit sensor 7 can control the drive motor 10 to stop, thereby limiting the moving stroke of the movable seat to ensure that it will not collide with other parts.

[0016] The working principle of the utility model is as follows: the substrate is first pulled to the feed winding roller 2, then passes through the adjusting roller 3, and then is sent to the hot melt adhesive spraying head 5 through the winding roller group 4 to glue the bag body substrate. When pulled to the gluing position, if the color mark sensor senses the color mark on the substrate, it means that the substrate has been accurately pulled into place and can be glued. If the color mark sensor senses that the color mark is pulled too far or does not sense the color mark, it means that the position of the substrate has shifted. At this time, the color mark sensor feeds back information to the controller, and the controller controls the drive motor 10 to drive the adjusting screw to rotate, and then drives the moving seat and the adjusting roller 3 to move a certain distance, driving the position of the substrate 1 to be fine-tuned until the color mark sensor can sense the color mark on the substrate, indicating that the position of the substrate has been adjusted into place, and the hot melt adhesive spraying head 5 can be controlled to glue the substrate.

[0017] The structure of the utility model adopts hot melt adhesive to glue the substrate, and the characteristics of hot melt adhesive can be used to achieve quick drying of the substrate after bonding, effectively reducing waiting time and thus improving the overall processing efficiency of the equipment; in addition, a color mark sensor is provided to sense the color mark on the substrate, and according to the detection situation, the moving seat is controlled to drive the adjustment roller to move to automatically fine-tune the position of the substrate, thereby ensuring the accuracy of the gluing position.
