Description

Technical Field

[0001] This utility model belongs to the field of cutting machinery and equipment manufacturing, and in particular relates to a sheet material cutting length positioning device. Background Technology

[0002] With the improvement of people's living standards and increasingly fierce commercial competition, various types of product packaging have emerged. Different packaging requires sheets of different sizes. However, existing sheet cutting methods are cumbersome, requiring the photoelectric detection head to be disassembled, adjusted, and then reinstalled. This process is complex, time-consuming, and labor-intensive, impacting production speed. Furthermore, once deviations are discovered after installation, fine-tuning is difficult, often resulting in large cutting tolerances. Therefore, there is a desire for a device that offers more convenient material cutting length positioning and better control over adjustment precision. Utility Model Content

[0003] The purpose of this invention is to provide a sheet cutting length positioning device that is easy to adjust, flexible, highly accurate, and adaptable to cutting sheets of different widths.

[0004] This utility model is achieved through the following technical solution:

[0005] A sheet material cutting length positioning device includes a frame 1 and a cutting unit 2 and a feeding unit 3 arranged sequentially on the frame 1. The cutting unit 2 is equipped with a cutter for cutting the sheet material. The feeding unit 3 is used to feed the cutting unit 2. The feeding unit 3 includes several rows of conveying rollers 4 located in the middle and two guide rails 5 located on both sides parallel to the feeding direction. An adjusting beam 6 that can move back and forth along the two guide rails 5 is slidably mounted between the two guide rails 5. A sliding seat 7 that can move back and forth along the adjusting beam 6 is slidably mounted on the adjusting beam 6. A linear drive device 8 is provided above the sliding seat 7. The moving direction of the movable end of the linear drive device 8 is perpendicular to the adjusting beam 6. An L-shaped mounting bracket 9 is also provided on the movable end of the linear drive device 8. One end of the L-shaped mounting bracket 9 is also connected to a hanger 10 whose height is adjustable relative to the L-shaped mounting bracket 9. A photoelectric detection head 11 is also provided at the bottom of the hanger 10.

[0006] Preferably, the linear drive device 8 is a first lead screw nut sleeve drive mechanism driven by a servo motor 12, and the nut sleeve on the first lead screw nut sleeve drive mechanism is the movable end of the linear drive device 8, and the L-shaped mounting bracket 9 is mounted on the nut sleeve.

[0007] Preferably, an adjustable stop block 13 is provided between the conveying rollers 4. The stop block 13 is driven to move by a linear drive mechanism, and the direction of movement is perpendicular to the feeding direction of the feeding unit, so as to stop the sheet material and prevent it from deviating during transportation. More preferably, the linear drive mechanism is a second lead screw and nut sleeve drive mechanism. The lead screw on the second lead screw and nut sleeve drive mechanism is driven to rotate by a handwheel 14. The stop block 13 is fixedly connected to the nut sleeve on the second lead screw and nut sleeve drive mechanism. When the lead screw rotates, the nut sleeve can move back and forth along the lead screw, thereby realizing the movement of the stop block to the required position to meet the transportation direction control of sheets of different widths.

[0008] Preferably, a locking buckle 15 is provided below the adjusting beam 6. When the adjusting beam 6 is manually adjusted to the correct position, it is locked onto the guide rail 5 by the locking buckle 15.

[0009] Preferably, the hanger 10 is provided with a vertical slide groove 16. The hanger 10 and the L-shaped mounting bracket 9 are locked together by locking bolts passing through the slide groove 16. When it is necessary to adjust the height of the hanger 10, loosen the locking bolts, then pull the hanger 10 up or down to the required position, and then tighten the locking bolts again.

[0010] The beneficial effects of this utility model are:

[0011] This utility model discloses a sheet cutting length positioning device with an ingenious structure. By moving the adjusting beam back and forth along the guide rail, the coarse adjustment of the photoelectric detection head relative to the cutter can be achieved. Then, by driving the linear drive device, the fine adjustment of the photoelectric detection head relative to the cutter can be achieved. By moving the slide back and forth along the adjusting beam, the photoelectric detection head can adapt to the detection of sheets of different widths. The photoelectric detection head can be moved up and down relative to the L-shaped support frame by the hanger. This facilitates the initial feeding of materials and adapts to the detection of sheets of different thicknesses. It is flexible in use, easy to adjust, and has high adjustment accuracy. The adjustment accuracy is easier to control, making it highly practical and worthy of promotion. Attached Figure Description

[0024] like Figure 1-9 As shown, the sheet cutting length positioning device includes a frame 1 and a cutting unit 2 and a feeding unit 3 arranged sequentially on the frame 1. The cutting unit 2 is equipped with a cutter for cutting the sheet. The feeding unit 3 is used to feed the cutting unit 2. The feeding unit 3 includes several rows of conveying rollers 4 located in the middle and two guide rails 5 located on both sides parallel to the feeding direction. An adjusting beam 6 that can move back and forth along the two guide rails 5 is slidably mounted between the two guide rails 5. A sliding seat 7 that can move back and forth along the adjusting beam 6 is slidably mounted on the adjusting beam 6. A linear drive device 8 is provided above the sliding seat 7. The moving direction of the movable end of the linear drive device 8 is perpendicular to the adjusting beam 6. An L-shaped mounting bracket 9 is also provided on the movable end of the linear drive device 8. One end of the L-shaped mounting bracket 9 is also connected to a hanger 10 whose height is adjustable relative to the L-shaped mounting bracket 9. A photoelectric detection head 11 is also provided at the bottom of the hanger 10.

[0025] The linear drive device 8 is a first lead screw nut sleeve drive mechanism driven by a servo motor 12. The nut sleeve on the first lead screw nut sleeve drive mechanism is the movable end of the linear drive device 8, and the L-shaped mounting bracket 9 is mounted on the nut sleeve.

[0026] Between the conveying rollers 4, an adjustable stop block 13 is also provided. The stop block 13 is driven to move by a linear drive mechanism, and the direction of movement is perpendicular to the feeding direction of the feeding unit, so as to stop the sheet material and prevent it from deviating during transportation. More preferably, the linear drive mechanism is a second lead screw and nut sleeve drive mechanism. The lead screw on the second lead screw and nut sleeve drive mechanism is driven to rotate by a handwheel 14. The stop block 13 is fixedly connected to the nut sleeve on the second lead screw and nut sleeve drive mechanism. When the lead screw rotates, the nut sleeve can move back and forth along the lead screw, thereby realizing the movement of the stop block to the required position to meet the transportation direction control of sheets of different widths.

[0027] The lead screw and nut sleeve drive mechanism used in this invention is a commonly used linear drive structure, which includes a lead screw and a nut sleeve threaded onto the lead screw. Guide rods are also provided on both sides of the nut sleeve to guide its translation. In use, the lead screw can be driven to rotate manually or by a motor.

[0028] Below the adjusting beam 6, there is also a locking buckle 15. When the adjusting beam 6 is manually adjusted to the correct position, it is locked onto the guide rail 5 by the locking buckle 15.

[0029] The hanger 10 is provided with a vertical slide groove 16. The hanger 10 and the L-shaped mounting bracket 9 are locked together by locking bolts passing through the slide groove 16. When it is necessary to adjust the height of the hanger 10, loosen the locking bolts, then pull the hanger 10 up or down to the required position, and then tighten the locking bolts again.

[0030] The positioning principle of this utility model:

[0031] Once the cutting length and the thickness and width of the material to be cut are determined, they can be adjusted flexibly according to the following methods as needed:

[0032] By manually moving the adjusting beam 6 back and forth along the guide rail 5, the coarse adjustment of the photoelectric detection head 11 relative to the cutter can be achieved. Then, by driving the linear drive device 8 driven by the servo motor 12, the fine adjustment of the photoelectric detection head 11 relative to the cutter can be achieved. Through the combination of coarse and fine adjustment, the cutting length can be determined well and conveniently with good accuracy.

[0033] By manually moving the slide 7 back and forth along the adjusting beam 6, the photoelectric detection head 11 can be adapted to detect sheets of different widths. The photoelectric detection head 11 can be moved up and down relative to the L-shaped support frame 9 by the hanger 10, which facilitates the initial sheet feeding and enables it to be adapted to the detection of sheets of different thicknesses.

[0034] By adjusting the position of the stop block 13 with the handwheel, the sheet material of different widths can be limited to meet the transportation direction control of the sheet material of different widths and prevent it from deviating.

[0035] The sheet cutting length positioning device of this utility model has an ingenious structure, is flexible in use, convenient in adjustment, and has high adjustment accuracy. The adjustment accuracy is easier to control, and it is highly practical and worth promoting.

[0036] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
