[0002] The fully automatic roll punching production line can realize one-step forming from coils to straight strip products. How to achieve fixed-length cutting of product parts is the key technology in the processing process. For the fully automatic production line, it is necessary to rely on a special detection device to collect the length signal and input it into the PLC control system, and then send a signal to the cutting mechanism for cutting.

DETAILED DESCRIPTION

[0019] The following is a further detailed description of the specific implementation of the utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the utility model.

[0020] like Figures 1 to 5 The utility model comprises a supporting roller 1, a measuring mechanism, a lifting cylinder 6 and an adjusting bracket 7. The measuring mechanism is mounted on the adjusting bracket 7. The measuring mechanism comprises a measuring wheel 2, a mounting seat 5, a measuring plate 10, an encoder 11 and a thickness measuring mechanism. The cylinder barrel of the lifting cylinder 6 is fixedly connected to the adjusting bracket 7, and the cylinder rod of the lifting cylinder 6 is fixedly connected to the mounting seat 5. The axle 3 of the measuring wheel 2 is mounted at the bottom of the mounting seat 5 through a bearing 4. In order to ensure the working position of the bearing 4, an axle stop 14 is provided on the axle 3. The axle 3 is connected to the encoder 11. A transversely arranged measuring plate 10 is fixedly connected to the right side of the mounting seat 5. The thickness measuring mechanism is mounted on the adjusting bracket 7 and is located above the measuring plate 10. The thickness measuring mechanism detects the height of the measuring plate 10. The measuring wheel 2 is located above the supporting roller 1, and the steel strip to be measured passes between the measuring wheel 2 and the supporting roller 1. This device is installed before the cutting equipment. The feeding mechanism of the cutting equipment drives the steel strip to move forward, and the lifting cylinder 6 descends, so that the measuring wheel 2 falls on the steel strip to be measured. Then, the measuring wheel 2 is driven to rotate during the forward movement of the steel strip to be measured. At the same time, the encoder 11 counts and measures the length of the steel strip to be measured. The thickness measuring device detects the thickness of the steel strip by detecting the undulating height of the measuring plate.

[0021] Furthermore, the thickness measuring mechanism comprises a sensor mounting plate 8 and a contact digital sensor 9, wherein the contact digital sensor 9 is mounted on the adjustment bracket 7 via the sensor mounting plate 8, and a probe 9-1 of the contact digital sensor 9 abuts against the top surface of the measuring plate 10. Figure 5 In the process, the different thickness of the steel strip will cause the measuring wheel 2 to be lifted or lowered. When the thicker part of the steel strip passes through the measuring wheel 2, Figure 5 In the middle b state, the measuring wheel 2 is lifted up, and since the cylinder rod of the lifting cylinder 6 is forced to lift up, the mounting seat 5 is also lifted up, and the measuring plate 10 on the mounting seat 5 rises, and the probe is lifted up. Figure 5 In the middle C state, as the cylinder rod of the lifting cylinder 6 descends, the measuring plate 10 descends, and the contact digital sensor 9 detects and records the thickness of the steel strip.

[0022] The adjustment bracket 7 includes a base 15, a transverse adjustment plate 16, a transverse adjustment slot 17, a transverse locking handle 18 and an angle adjustment mechanism. The adjustment bracket 7 is provided with a transverse adjustment slot 17. One end of the transverse adjustment plate 16 matches and passes through the transverse adjustment slot 17. The side wall of the transverse adjustment slot 17 is provided with a transverse locking screw hole. An adjustment bolt is screwed into the transverse locking screw hole. One end of the adjustment bolt presses against the transverse adjustment plate 16, and the other end is connected to the transverse locking handle 18. The other end of the transverse adjustment plate 16 is fixedly connected to the cylinder barrel of the lifting cylinder 6 through the angle adjustment mechanism. The position of the angle adjustment mechanism can be adjusted by pulling the transverse adjustment plate, and the locking function of the transverse position adjustment can be realized by rotating the transverse locking handle 18. In order to prevent the transverse adjustment plate 16 from shaking in the transverse adjustment slot after the adjustment bolt presses against the transverse adjustment plate 16, a pad 19 is also provided. A pad 19 is provided between the transverse adjustment plate 16 and the transverse adjustment slot 17. Inserting the pad 19 into the transverse adjustment groove 17 can fill the gap between the transverse adjustment groove 17 and the transverse adjustment plate 16 .

[0023] In order to ensure that the measuring wheel 2 and the steel belt are in the same direction, an angle adjustment mechanism is also provided, which includes an angle adjustment plate 22, an angle locking handle 23 and a cylinder connecting plate 24. An angle adjustment screw hole is provided at one end of the transverse adjustment plate 16, and a transverse bolt is provided at the bottom end of the angle locking handle 23. The bolt passes through the angle adjustment screw hole and is fixed to the angle adjustment plate 22. The cylinder barrel of the lifting cylinder 6 is installed on the angle adjustment plate 22 through the cylinder connecting plate 24. When the lifting cylinder 6 drives the measuring wheel 2 to press down on the steel belt, the measuring wheel 2 and the steel belt have basically the same direction of travel. In order to ensure that the measuring wheel 2 and the steel belt are in the same direction of travel, the position of the lifting cylinder 6 can be adjusted by adjusting the position of the angle adjustment plate.

[0024] Furthermore, the adjustment bracket 7 further includes a height adjustment block 20 and a height fixing block 21, wherein the height adjustment block 20 is fixedly connected to the transverse adjustment slot 17, the height fixing block 21 is fixed to the base 15, blocks are provided on both sides of the height adjustment block 20, and slots are provided on both sides of the height fixing block 21, the blocks and the slots are slidably matched, a slot hole is provided on the height adjustment block 20, a screw is provided in the slot hole, and the height adjustment block 20 is locked with the height fixing block 21 by the screw. The height adjustment block 20 slides up and down relative to the height fixing block 21 and is locked by the screw, so that the position of the mounting seat 5 can be raised and lowered, thereby adjusting the working position of the measuring wheel 2.

[0025] Specifically, an encoder mounting plate 12, an elastic coupling 13 and an axle stop 14 are provided, the encoder 11 is mounted on the encoder mounting plate 12, the top of the encoder mounting plate 12 is fixed on the mounting seat 5, and the encoder 11 is connected to the axle 3 of the measuring wheel 2 through the elastic coupling 13. The stability of the shaft transmission from the measuring wheel 2 to the encoder 11 is ensured.

[0026] Working principle: This device is installed before the cutting equipment. The feeding mechanism of the cutting equipment drives the steel belt to move forward, and the lifting cylinder 6 descends, and the measuring wheel 2 falls on the steel belt to be measured. Then, the steel belt to be measured drives the measuring wheel 2 to rotate during the forward movement. At the same time, the encoder 11 counts and measures the length of the steel belt to be measured. The measuring wheel will fluctuate with the thickness of the steel belt, thereby driving the measuring plate to fluctuate. The probe detects the fluctuation height of the measuring plate and the thickness of the steel belt, thereby providing a basis for the shearing action of the cutting mechanism.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
