DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Refer to Figures 1-4, A material feeding device for a bag making machine, comprising a workbench 1. A placing plate 2 is fixedly installed on the top of the workbench 1. A placing groove 3 is formed on the top of the placing plate 2. A material feeding roller 4 is lapped inside the placing groove 3. An anti - detachment component is arranged on the top of the placing plate 2. The anti - detachment component includes a mounting plate 5 arranged on the top of the placing plate 2. The mounting plate 5 is in an L - shaped structure and is made of metal material, which is convenient for the mounting plate 5 to have higher structural strength, so that the mounting plate 5 is more durable. An electric push rod 6 is fixedly installed on the top of the mounting plate 5. A pressing plate 7 is fixedly installed at the output end of the electric push rod 6. After the material feeding roller 4 is placed, the electric push rod 6 can be used to make the pressing plate 7 move downward, so that the pressing plate 7 fits with the placing plate 2, which is convenient for limiting the material feeding roller 4 and avoiding the phenomenon that the material feeding roller 4 falls off from the placing groove 3 during use. A first limiting component is arranged on the top of the workbench 1, and a second limiting component is arranged on the top of the workbench 1. Fixed frames 12 are fixedly installed on the front side and the rear side of the workbench 1. A screw rod 13 is rotatably connected inside the fixed frame 12. A moving block 14 is threadedly connected to the surface of the screw rod 13, and the moving block 14 is slidably connected to the fixed frame 12. A guiding roller 15 is rotatably connected inside the moving block 14. A driving motor 16 is fixedly installed at the bottom of the workbench 1. A rotating shaft 17 is fixedly installed at the output end of the driving motor 16. A first sprocket 18 is fixedly installed on the surface of the rotating shaft 17. A chain 19 is meshed on the surface of the first sprocket 18. A second sprocket 20 is meshed on the inner wall of the chain 19, and the second sprocket 20 is fixedly connected to the screw rod 13. The first limiting component includes a first fixing plate 8 arranged on the top of the workbench 1. A first limiting roller 9 is rotatably connected inside the first fixing plate 8. The number of the first fixing plates 8 is multiple, and the multiple first fixing plates 8 are symmetrically distributed, which is convenient for more stably supporting the first limiting roller 9. The second limiting component includes a second fixing plate 10 arranged on the top of the workbench 1. A second limiting roller 11 is rotatably connected inside the second fixing plate 10. By using the first limiting component and the second limiting component in cooperation, it is convenient to limit the material tape, so that the guiding roller 15 can better adjust the tightness of the material tape. Support legs 21 are fixedly installed at the bottom of the workbench 1. Anti - slip pads are arranged at the bottoms of the support legs 21, which is convenient for supporting the workbench 1 and avoiding the phenomenon that the device is prone to sliding during use. For this material feeding device of the bag making machine, when the running material tape becomes loose, the driving motor 16 is used to make the rotating shaft 17 and the first sprocket 18 rotate, so that the chain 19 rotates, and the second sprocket 20 and the screw rod 13 rotate simultaneously, so that the moving block 14 and the guiding roller 15 move upward until the guiding roller 15 moves upward to a suitable height to straighten the running material tape, which is convenient for adjusting the position of the guiding roller 15, achieving the goal of adjusting the tightness of the running material tape and avoiding the problem that the running material tape has wrinkles due to looseness.

[0021] The material feeding device of this bag making machine is connected to the 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0022] During use: Place the unwinding roller 4 with the material tape roll on it into the placement groove 3, start the electric push rod 6, so that the pressing plate 7 moves downward until the pressing plate 7 fits against the placement plate 2. Pass one end of the material tape roll through the first limiting roller 9, the guiding roller 15 and the second limiting roller 11 in sequence, and finally place one end of the material tape roll into the bag making machine. When the bag making machine is working, the material tape is fed through the coordinated use of the first limiting roller 9, the guiding roller 15 and the second limiting roller 11. When the fed material tape becomes slack, start the driving motor 16, so that the rotating shaft 17 rotates, so that the first sprocket 18 rotates, so that the chain 19 rotates, so that the second sprocket 20 rotates, so that the screw rod 13 rotates simultaneously, so that the moving block 14 moves upward along the fixed frame 12, driving the guiding roller 15 to move upward until the guiding roller 15 moves upward to an appropriate height, and the fed material tape can be made straight.

[0023] To sum up, for the material feeding device of this bag making machine, when the fed material tape becomes slack, the driving motor 16 is used to rotate the rotating shaft 17 and the first sprocket 18, so that the chain 19 rotates, so that the second sprocket 20 and the screw rod 13 rotate simultaneously, so that the moving block 14 and the guiding roller 15 move upward until the guiding roller 15 moves upward to an appropriate height, making the fed material tape straight, facilitating the adjustment of the position of the guiding roller 15, achieving the goal of being able to adjust the tightness of the fed material tape, avoiding the problem that the fed material tape wrinkles due to slack, and solving the problems raised in the above background technology.
