Description
Technical Field
[0001] This utility model relates to the field of nonwoven packaging bag technology, specifically a packaging slitting machine with calibration function. Background Technology
[0002] Non-woven bags, also known as non-woven fabric bags, are a green product that is tough, durable, aesthetically pleasing, breathable, reusable, washable, and can be screen-printed with advertisements and labels. They have a long service life. Before producing non-woven packaging bags, the non-woven raw materials need to be cut to obtain non-woven raw materials of specified specifications.
[0003] A packaging bag slitting machine disclosed in CN202321506094.0 includes a frame, an unwinding roller, a slitting mechanism, and a winding mechanism. The unwinding roller is rotatably mounted on the frame. The winding mechanism includes two sets of winding assemblies and a drive mechanism for driving the two sets of winding assemblies to rotate synchronously in opposite directions. Each winding assembly includes a winding roller, a rotating shaft, and a driven gear. The winding roller and the driven gear are coaxially mounted on the rotating shaft, which is mounted on the frame. Two driven gears in the two sets of winding assemblies are meshed together. The slitting mechanism is mounted on the frame and is located between the unwinding roller and the winding mechanism.
[0004] The above-mentioned packaging bag slitting machine has some problems in actual operation. For example, the slitting blade is directly fixed on the blade holder. When different specifications need to be cut, the slitting blade needs to be manually removed from the blade holder and then its position changed. This method of manually changing the position of the slitting blade has low accuracy. The calibration work mostly relies on manual measurement, which has poor accuracy and is not suitable for cutting packaging bags of different specifications separately. Therefore, we propose a packaging slitting machine with calibration function. Utility Model Content

[0023] Please see Figure 1-3 This embodiment provides a technical solution: a packaging slitting machine with calibration function, including a workbench 1 and a calibration slitting mechanism 3;
[0024] Workbench 1: An upper mounting bracket 2 is fixedly connected between the upper sides of its left and right inner walls. It also includes a microcontroller 8, which is located on the right side of the workbench 1. The input end of the microcontroller 8 is electrically connected to an external power source.

It also includes an unwinding roller 10, which is rotatably connected to the front side of the upper surface of the workbench 1 through a bearing seat. When the slitting machine is needed, the nonwoven fabric conveying cylinder can be fixed on the unwinding roller 10. Then, the nonwoven fabric conveying line on the nonwoven fabric conveying cylinder can be manually guided to pass through the first guide roller 9 in sequence, and then guided by the three second guide rollers 11 to tighten the entire nonwoven fabric conveying line. Then, the nonwoven fabric conveying line can be connected to an external winding machine.
[0025] The calibration and slitting mechanism 3 includes an upper sliding groove 31, a first lead screw 32, a limiting rod 33, a calibration block 34, and a cold cutting blade 35. The upper sliding grooves 31 are symmetrically arranged on the front side of the upper mounting bracket 2. The interiors of the two upper sliding grooves 31 are rotatably connected to the first lead screw 32, with adjacent ends of the two first lead screws 32 fixedly connected. The thread directions of the two first lead screws 32 are opposite. Calibration blocks 34 are slidably connected inside both upper sliding grooves 31. Evenly distributed limiting rods 33 are fixedly connected between the left and right inner walls of the worktable 1. Both calibration blocks 34 are slidably connected to the two limiting rods 33. Cold cutting blades 35 are provided on the front side of both calibration blocks 34. A cold cutting blade 35 is also provided in the middle of the front side of the upper mounting bracket 2. The calibration and slitting mechanism 3 also includes a lower sliding groove. The mounting frame 36 comprises a second lead screw 37, a roller mounting base 38, and a slitting roller 39. The lower mounting frame 36 is located on the lower side between the left and right inner walls of the worktable 1. The upper surface of the lower mounting frame 36 has symmetrically arranged lower sliding grooves. A second lead screw 37 is rotatably connected inside each of the two lower sliding grooves, with adjacent ends of the two second lead screws 37 fixedly connected. The threads of the two second lead screws 37 are in opposite directions. A roller mounting base 38 is slidably connected inside each of the two lower sliding grooves. The middle portion of the roller mounting base 38 is threadedly connected to the external thread surface of the second lead screw 37 located in the same lower sliding groove. A roller mounting base 38 is also fixedly connected to the middle of the upper surface of the lower mounting frame 36. A slitting roller 39 is rotatably connected inside each of the three roller mounting bases 38. The three slitting rollers... Each roller 39 has a slitting groove in the middle of its outer arc surface. The slitting roller 39 and the cold cutting blade 35 are positioned vertically to each other. The system also includes a drive mechanism 4, which consists of a first sprocket 41, a second sprocket 42, a chain 43, and a motor 44. The first sprocket 41 is fixedly connected to the right end of the second lead screw 37 on the right side. The right end of the first lead screw 32 on the right side is fixedly connected to the second sprocket 42. The first sprocket 41 and the second sprocket 42 are connected by the chain 43. The motor 44 is located on the upper side of the left side of the worktable 1. The output shaft of the motor 44 is fixedly connected to the left end of the first lead screw 32 on the left side. The input end of the motor 44 is electrically connected to the output end of the microcontroller 8. The system also includes a position sensor 5, which is located on the right side of the cold cutting blade 35 in the middle. A signal receiving board is provided on the left side of the cutter 35, and a scale line 6 is provided on the upper surface of the front surface of the upper mounting bracket 2. Each of the three cold-cutting cutters 35 has a calibration head on its upper surface, with the three calibration heads corresponding to the scale line 6. The position sensor 5 is bidirectionally electrically connected to the microcontroller 8. An air inlet pipe 7 is fixedly connected to the upper side between the left and right inner walls of the worktable 1. The air inlets of the three cold-cutting cutters 35 are connected to an air inlet pipe 7 via air connecting pipes. The right end of the air inlet pipe 7 is connected to an external air pump. The non-woven fabric conveyor then passes between the non-woven fabric conveyor lines, with the lower surface of the non-woven fabric conveyor line resting on the outer surface of the three slitting rollers 39. When the non-woven fabric needs to be slit into processing materials of different widths according to the packaging bag processing requirements, the microcontroller 8 and position sensor 5 can be controlled to operate.The distance between the middle cold-cutting blade 35 and the right-side cold-cutting blade 35 is measured. Since the positions of the right-side cold-cutting blade 35 and the left-side cold-cutting blade 35 are symmetrical, the distance between the middle cold-cutting blade 35 and the right-side cold-cutting blade 35 is also the distance between the middle cold-cutting blade 35 and the left-side cold-cutting blade 35. When the specified distance between the three cold-cutting blades 35 needs to be adjusted, the microcontroller 8 can be controlled to operate the motor 44. The output shaft of the motor 44 rotates in both directions, thereby driving the two first lead screws 32 to rotate synchronously in both directions. This, in turn, drives the first sprocket 41 to rotate synchronously in both directions through the second sprocket 42 and the chain 43, which in turn drives the two lower second lead screws 37 to rotate synchronously in both directions. This, in turn, causes the two calibration blocks 34 to move closer and closer to each other. The three cold-cutting blades 35 move away from each other, causing the left and right cold-cutting blades 35 to move closer and further apart. Simultaneously, the left and right roller mounting bases 38 move closer and further apart in sync. During this process, the position sensor 5 measures the distance between the three cold-cutting blades 35 in real time and sends this information back to the microcontroller 8 as electrical signals, enabling precise calibration. Once the three cold-cutting blades 35 are adjusted to the specified angle, the microcontroller 8 is activated, causing the three blades 35 to rotate at high speed. This activates the external air pump, causing the rotating blades of the three cold-cutting blades 35 to extend and insert into the corresponding slitting grooves, continuously performing the slitting operation.
[0026] The working principle of the packaging slitting machine with calibration function provided by this utility model is as follows: When the slitting machine is needed, the non-woven fabric conveying cylinder is fixed on the unwinding roller 10, and then the non-woven fabric conveying line on the non-woven fabric conveying cylinder is manually guided to pass through the first guide roller 9 in sequence. The non-woven fabric conveying line then passes between the non-woven fabric conveying lines, and the lower surface of the non-woven fabric conveying line rests on the outer surface of the three slitting rollers 39. Then, it is guided by the three second guide rollers 11 for a second time, tightening the entire non-woven fabric conveying line. Finally, the non-woven fabric conveying line is connected to the outside. On the winding machine, when the non-woven fabric needs to be cut into processing materials of different widths according to the packaging bag processing requirements, the microcontroller 8 and position sensor 5 can be adjusted to operate and measure the distance between the middle cold-cutting blade 35 and the right cold-cutting blade 35. Because the positions of the right cold-cutting blade 35 and the left cold-cutting blade 35 are symmetrical, the distance between the middle cold-cutting blade 35 and the right cold-cutting blade 35 is also the distance between the middle cold-cutting blade 35 and the left cold-cutting blade 35. When the specified distance between the three cold-cutting blades 35 needs to be adjusted, the microcontroller 8 and motor 44 can be adjusted to operate. The output shaft of motor 44 rotates in both directions, thereby driving the two first lead screws 32 to rotate synchronously in both directions. This, in turn, drives the first sprocket 41 to rotate synchronously in both directions via the second sprocket 42 and chain 43. This, in turn, drives the two lower second lead screws 37 to rotate synchronously in both directions, causing the two alignment blocks 34 to move closer and further apart. This, in turn, causes the left and right cold cutting blades 35 to move closer and further apart. Simultaneously, the left and right roller mounting bases 38 rotate synchronously. During the relatively close and relatively far operations, the position sensor 5 measures the distance between the three cold cutting blades 35 in real time and returns this information to the microcontroller 8 in real time as an electrical signal, thus completing the precise calibration operation. When the three cold cutting blades 35 are adjusted to the specified angle, the microcontroller 8 can be controlled to operate the three cold cutting blades 35. The blades of the three cold cutting blades 35 rotate at high speed, which can control the external air pump. The blades of the three cold cutting blades 35 that are operating extend and enter the slitting grooves at the corresponding positions to continuously perform slitting operations.
[0027] It is worth noting that the microcontroller 8 disclosed in the above embodiments is specifically model S7-200. The cold cutting blade 35, motor 44 and position sensor 5 can be freely configured according to the actual application scenario. It is recommended that the cold cutting blade 35 be a ZK-005 model pneumatic shearing slitting blade, the motor 44 be an SGM7G type servo motor, and the position sensor 5 be a GP2Y0A02YK0F infrared ranging sensor. The microcontroller 8 controls the operation of the cold cutting blade 35, motor 44 and position sensor 5 using methods commonly used in the prior art.
[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. 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.
