TECHNICAL FIELD

[0001] The utility model relates to a cutting counting equipment technical field, concretely to automatic cutting counting device of ultrathin silicon steel strip. BACKGROUND

[0002] As a kind of key electronic material, ultrathin silicon steel strip is widely used in transformer, motor, sensor and many other electronic equipment and power system, and it can significantly improve the performance and efficiency of electronic equipment due to its high magnetic permeability, low iron loss and other excellent characteristics. In actual production and application process, it is often necessary to cut the coiled ultrathin silicon steel strip according to specific specifications to meet the production needs of different products.

[0003] Traditional ultrathin silicon steel strip cutting work mainly relies on manual operation or semi-automatic equipment. In manual cutting mode, workers need to manually measure the length of the strip and position the cutting location. The operation process is not only inefficient, but also difficult to ensure the consistency and accuracy of the cutting size due to human factors such as fatigue and lack of concentration, resulting in uneven product quality. In addition, when manually counting the number of cut strips, it is easy to miss or miscount, which brings great difficulty to production management and inventory statistics. SUMMARY

[0004] The purpose of the utility model is to provide an automatic cutting counting device for ultrathin silicon steel strip to solve the problem of manual counting mentioned in the background technology, which is prone to miss or miscount, and brings great difficulty to production management and inventory statistics.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an automatic cutting counting device for ultrathin silicon steel strip, comprising a cutting table, a support seat fixedly connected to the surface of the cutting table, a rotating shaft rotatably connected to the surface of the support seat, a cutter fixedly connected to the surface of the rotating shaft, a gear fixedly connected to the surface of the rotating shaft, a servo motor fixedly connected to one side of the cutting table, a rotary encoder fixedly connected to the output shaft of the servo motor through a shaft coupling, a PLC controller fixedly connected to the working end of the rotary encoder, a photoelectric sensor fixedly installed on the surface of the cutting table, a rechecking mechanism provided on the surface of the support seat, the rechecking mechanism comprising a guide block, a guide rod slidably connected to the surface of the guide block, a pressing plate fixedly connected to the surface of the guide rod, a spring fixedly connected to the surface of the pressing plate, a guide block fixedly connected to the end of the spring away from the pressing plate, a cam fixedly connected to the surface of the rotating shaft, a support box fixedly connected to the surface of the support seat, and a press-type counter inserted into the surface of the support box.

[0006] Preferably, the photoelectric sensor signal line is connected to the input port of the PLC controller, and the output line of the rotary encoder is connected to the counting input port of the PLC controller.

[0007] Preferably, the output port of the photoelectric sensor is input to the control circuit of the servo motor through an intermediate relay, and the PLC controller receives the detection signal from the photoelectric sensor and the rotation signal from the rotary encoder.

[0008] Preferably, the servo motor drives the rotating shaft to rotate on the servo motor through the output shaft, and the rotating shaft drives the cutter to rotate synchronously. The rotating shaft and gears are provided in two sets, and the two sets of gears mesh with each other. The two sets of rotating shafts rotate synchronously on the support base through the two sets of gears, and the rotation directions are opposite.

[0009] Preferably, a guide hole is formed on the surface of the guide block, the guide rod slides on the guide hole of the guide block, and the elastic force of the spring acts directly on the pressing plate.

[0010] Preferably, the cam is provided in two sets and is located on two sets of rotating shafts respectively. The cam is elliptical in shape and the rotating shaft is located at the eccentric position of the cam. The cam slides on one side of the servo motor by rotating and pressing the pressing plate.

[0011] Preferably, a groove is formed on the surface of the support box, the push-to-react counter is inserted into the groove of the support box, and the pressing plate presses the counting switch of the push-to-react counter during the sliding process.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This slitting and counting device uses photoelectric sensors to detect the slitting position of the strip and transmits the signal to the PLC controller, avoiding errors caused by manual measurement and positioning, ensuring accurate cutting position, and improving the consistency of slitting dimensions. A rotary encoder is connected to the shaft at one end of the cutter to record the number of rotations of the cutter, and its signal is also transmitted to the PLC controller to provide a basis for accurate counting. Based on the received signals from the photoelectric sensor and rotary encoder, the PLC controller controls the motor to run through an intermediate relay to achieve automatic slitting without manual operation, thus improving slitting efficiency. At the same time, the PLC controller accurately calculates the quantity of strip after slitting and transmits it to the display screen for real-time display, avoiding omissions and miscounts that occur with manual counting, and facilitating production management and inventory statistics.

[0014] This slitting and counting device works by rotating a shaft to drive a cam to rotate on one side of the support base during slitting. The cam, during rotation, presses a pressure plate to one side and returns to its original position under the spring force, thus achieving reciprocating motion of the pressure plate on one side of the support base. A push-button counter is inserted into the groove of the support box. As the pressure plate moves, it continuously presses the counting switch of the push-button counter, thus achieving push-button counting of the slitting. This inspection mechanism, using the principle of push-button technology, can verify the original count. When a large deviation occurs in the count data, it indicates a malfunction in the counting device, reminding operators to inspect and repair it, thus reducing the production impact caused by equipment failure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 One embodiment provided by this utility model:

[0023] An automatic slitting and counting device for ultra-thin silicon steel strip includes a slitting table 1, a support base 11 fixedly connected to the surface of the slitting table 1, a rotating shaft 12 rotatably connected to the surface of the support base 11, a cutter 13 fixedly connected to the surface of the rotating shaft 12, a gear 14 fixedly connected to the surface of the rotating shaft 12, a servo motor 2 fixedly connected to one side of the slitting table 1, a rotary encoder 21 fixedly connected to the output shaft of the servo motor 2 via a coupling, a PLC controller 22 fixedly connected to the working end of the rotary encoder 21, and a photoelectric sensor 23 fixedly mounted on the surface of the slitting table 1. The rotary encoder 21 can detect the number of rotations of a rotating object, while the photoelectric sensor 23 can locate the slitting position of the strip. A re-inspection mechanism is provided on the surface of the support base 11, the re-inspection mechanism including a guide block 3, a guide rod 31 slidably connected to the surface of the guide block 3, and the guide rod 31... A pressing plate 32 is fixedly connected to the surface of the device. A spring 33 is fixedly connected to the surface of the pressing plate 32. A guide block 3 is fixedly connected to the end of the spring 33 away from the pressing plate 32. A cam 34 is fixedly connected to the surface of the rotating shaft 12. A support box 35 is fixedly connected to the surface of the support base 11. A pressing counter 36 is inserted into the surface of the support box 35. This device can determine the cutting position of the strip material through the photoelectric sensor 23, thereby ensuring cutting quality and improving cutting efficiency. The rotary encoder 21 records the number of cuts by the cutter 13, and the PLC controller 22 calculates the number of cut strip materials, avoiding omissions and miscounts, and ensuring the rigor of production management and inventory statistics. In addition, the re-inspection mechanism adopts the principle of pressing technology, which can check the original count. When the count data has a large deviation, it indicates that the counting device has malfunctioned, reminding the operator to check and repair, reducing the production impact caused by equipment failure.

[0024] Furthermore, the signal line of the photoelectric sensor 23 is connected to the input port of the PLC controller 22, and the output line of the rotary encoder 21 is connected to the counting input port of the PLC controller 22 for synchronously recording the number of rotations of the slitting blade 13 and transmitting the rotation signal to the PLC controller 22. The photoelectric sensor 23 is located near the strip slitting position, and the power line of the photoelectric sensor 23 is connected to the positive terminal of the DC power supply provided by the PLC controller 22. The ground line of the photoelectric sensor 23 is connected to the negative terminal of the DC power supply.

[0025] Furthermore, the output port of the photoelectric sensor 23 is input to the control circuit of the servo motor 2 through an intermediate relay. The PLC controller 22 receives the detection signal from the photoelectric sensor 23 and the rotation signal from the rotary encoder 21, and controls the motor to realize the strip cutting operation and accurately calculate the quantity of strip after cutting. When the contacts of the intermediate relay are connected to the control circuit of the servo motor 2, the coil of the intermediate relay is energized and the contacts close when the PLC controller 22 outputs a control signal, thereby connecting the control circuit of the motor. The PLC controller 22 is also connected to a display screen, and the PLC controller 22 transmits the calculated quantity information of the strip after cutting to the display screen for real-time display.

[0026] Furthermore, the servo motor 2 drives the rotating shaft 12 to rotate on the servo motor 2 through the output shaft. The rotating shaft 12 drives the cutter 13 to rotate synchronously. There are two sets of rotating shaft 12 and gears 14, and the two sets of gears 14 mesh with each other. The two sets of rotating shaft 12 rotate synchronously on the support base 11 through the two sets of gears 14, and the rotation directions are opposite. The two sets of cutters 13 cut the strip during the rotation process, and the cutting position of the strip is driven by the photoelectric sensor 23 to ensure the cutting quality.

[0027] Furthermore, a guide hole is provided on the surface of the guide block 3, the guide rod 31 slides on the guide hole of the guide block 3, and the elastic force of the spring 33 acts directly on the pressing plate 32, ensuring the stability of the pressing plate 32 on one side of the support base 11, and the pressing plate 32 will return to its original position after sliding on the support base 11.

[0028] Furthermore, there are two sets of cams 34, which are located on two sets of rotating shafts 12 respectively. The cams 34 are elliptical in shape, and the rotating shafts 12 are located at the eccentric position of the cams 34. The cams 34 slide on one side of the servo motor 2 by rotating and pressing the pressing plate 32. When the pressing plate 32 is not pressing, the pressing plate 32 returns to its original position and waits to be pressed again. At this time, the pressing plate 32 will slide back and forth once on one side of the support seat 11 for each side cut by the cutter 13.

[0029] Furthermore, a groove is provided on the surface of the support box 35, and the push-to-react counter 36 is inserted into the groove of the support box 35. During the sliding process, the pressing plate 32 presses the counting switch of the push-to-react counter 36. The counting switch of the push-to-react counter 36 is located on one side of the pressing plate 32, while the reset switch and display screen of the push-to-react counter 36 are located on the other side. The pressing plate 32 continuously triggers the push-to-react counter 36 to count by reciprocating movement, thereby enabling the verification of the split count.

[0030] Working principle: The photoelectric sensor 23 is set near the strip cutting position to detect the cutting position and transmit the signal to the PLC controller 22, avoiding errors in manual measurement and positioning, ensuring accurate cutting position, and improving the consistency of cutting size. The rotary encoder 21 is connected to the rotating shaft 12 at one end of the cutter 13 and records the number of rotations of the cutter 13. Its signal is also transmitted to the PLC controller 22 to provide a basis for accurate counting. Based on the received signals from the photoelectric sensor 23 and the rotary encoder 21, the PLC controller controls the motor to run through the intermediate relay to achieve automatic cutting without manual operation, improving cutting efficiency. At the same time, the PLC controller 22 accurately calculates the quantity of strip after cutting and transmits it to the display screen for real-time display, avoiding omissions and miscounts when counting manually, and facilitating production management and inventory statistics.

[0031] When the cutter 13 is cutting, the rotating shaft 12 drives the cam 34 to rotate on one side of the support base 11. During the rotation, the cam 34 presses the pressing plate 32 to one side and returns to its original position under the elastic force of the spring 33, thereby realizing the reciprocating motion of the pressing plate 32 on one side of the support base 11. The pressing counter 36 is inserted into the groove of the support box 35. During the movement, the pressing plate 32 will continuously press the counting switch of the pressing counter 36, thereby realizing the pressing counting of the cutting. This inspection mechanism adopts the principle of pressing technology and can check the original count. When the count data has a large deviation, it indicates that the counting device has malfunctioned, reminding the operator to check and repair, thus reducing the production impact caused by equipment failure.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
