Description

Technical Field

[0001] The present invention relates to the technical field of turning processing, and particularly to a turning device for thin film burr removal and recycling. Background Art

[0002] Teflon thin film has extremely wide applications in many fields due to its excellent properties such as high and low temperature resistance, corrosion resistance, and non-stickiness.

[0003] In the production and manufacturing process of Teflon thin film, turning technology is one of the important means to process the Teflon thin film blank into a thin film product that meets specific requirements. The existing turning technology usually fixes the Teflon thin film blank on a specific turning device, and uses a high-precision turning tool to machine the blank to achieve the required dimensional accuracy requirements such as the thickness and width of the thin film. However, in the actual turning process, there are still some key problems to be solved urgently.

[0004] In the processing flow of the thin film, the position deviation of the thin film is a common and seriously affecting situation. At present, industry-wide, opposed photoelectric sensors are generally used to monitor whether the thin film has a position deviation. However, the existing opposed photoelectric sensors have obvious limitations. They lack an effective fault detection and maintenance mechanism. When the opposed photoelectric sensor accidentally fails, it cannot be detected and discovered in time. This leads to the inability to issue corresponding warning signals in time when the thin film actually deviates, which has an extremely adverse impact on the stability and reliability of the thin film processing process, and reduces the processing quality and production efficiency of the thin film product. Summary of the Invention

[0005] The present invention relates to a turning device for thin film burr removal and recycling, which solves the problem that although an opposed photoelectric sensor is used to monitor whether the Teflon thin film has a deviation during turning processing, due to the lack of an effective fault detection and maintenance mechanism, it is difficult to detect when the sensor fails, resulting in difficulty in warning when there is a deviation, and affecting the processing stability and reliability.

[0006] The present invention provides a turning device for thin film burr removal and recycling, specifically including: a machine body. On the left front of the top surface of the machine body, a mounting block a is fixedly installed. On the front surface of the mounting block a, a motor a is fixedly installed. The rotating shaft end of the motor a penetrates the rear surface of the mounting block a and is fixedly connected to a screw a. On the top surface of the machine body, two sets of slide rail assemblies a are fixedly installed symmetrically in the front and rear at a position adjacent to the right side of the screw a. On the tops of the sliders in the two sets of slide rail assemblies a, a supporting block is fixedly installed together. On the top surface of the supporting block, a turning tool is installed. A set of slide rail assembly b is fixedly installed in the area on the right side of the center of the top surface of the machine body. A mating plate a is fixedly installed on the top of the slider in the slide rail assembly b. A through-beam photoelectric sensor is fixedly installed on the rear end surface of the mating plate a. The transmitting end of the through-beam photoelectric sensor is installed in the upper area, while the receiving end of the through-beam photoelectric sensor is installed in the lower area. A set of slide rail assembly c is fixedly installed in the area adjacent to the right side of the slide rail assembly b on the top surface of the machine body. A mating plate b is fixedly installed on the top of the slider in the slide rail assembly c. A set of electric push rods is fixedly installed on the right end surface of the mating plate b. The push rod end of the electric push rod penetrates through the left end surface of the mating plate b and is fixedly installed with an interference plate. The bottom end surface of the interference plate is higher than the receiving end of the through-beam photoelectric sensor.

[0007] Further, a set of slide rail assembly d is fixedly installed on the top surface of the machine body in the area on the right side of the slide rail assembly c. A slitting tool is fixedly installed on the top of each of the two sliders in the slide rail assembly d.

[0008] Further, a side mounting plate is fixedly installed on the top surface of the machine body. The side mounting plate is located at the rear side of the middle area between the two sets of slide rail assemblies a. A set of electric cylinders is fixedly installed on the right end surface of the side mounting plate. The push rod end of the electric cylinder penetrates through the left end surface of the side mounting plate and is fixedly connected to the right end surface of a supporting block.

[0009] Further, two mounting blocks b are fixedly installed on the top surface of the machine body in a front-back symmetric manner. The mounting blocks b are located in the middle area between the electric cylinder and the slide rail assembly b. Three conveying rollers are rotatably installed among the two mounting blocks b in a uniformly distributed manner.

[0010] Further, two nuts a are threadedly installed on the screw a. Two annular clamping plates a are inserted on the screw a in the middle area between the two nuts a.

[0011] Further, a mounting block c is fixedly installed on the front right side of the top surface of the machine body. A motor b is fixedly installed on the front end surface of the mounting block c. The rotating shaft end of the motor b penetrates through the rear end surface of the mounting block c and is fixedly connected to a screw b. Two nuts b are threadedly installed on the screw b. Two annular clamps b are inserted on the screw b in the middle area between the two nuts b. A winding sleeve is inserted on the screw b in the middle area between the two annular clamps b.

[0012] Further, a control box is installed on the front end surface of the machine body. The control box is electrically connected to the motor a, the electric cylinder, the through-beam photoelectric sensor, the electric push rod and the motor b. A warning light strip is installed around the outer end surface of the machine body. The warning light strip is electrically connected to the control box.

[0013] Further, a fault determination timing module a and a fault determination timing module b which are electrically connected to the control box are arranged inside the control box; the timing value of the fault determination timing module a is five minutes; the timing value of the fault determination timing module b is five seconds; when the timing value of the fault determination timing module a is reached, the fault determination timing module a feeds back a signal to the control box, and the control box controls the push rod end of the electric push rod to extend and controls the start of timing of the fault determination timing module b; when the push rod end of the electric push rod is fully extended, at this time, the interference plate is in the optical path position between the emitting end and the receiving end of the opposed photoelectric sensor, interfering with the light beam emitted by the emitting end, so that the intensity of the optical signal received by the opposed photoelectric sensor decreases, thereby triggering the threshold value set by the opposed photoelectric sensor; when the optical signal received by the opposed photoelectric sensor reaches its specified threshold value, it feeds back a signal to the control box, and the control box controls the warning light belt to start; when the timing value of the fault determination timing module b is reached, the fault determination timing module b feeds back a signal to the control box, and the control box controls the push rod end of the electric push rod to retract and controls the start of timing of the fault determination timing module a; when the push rod end of the electric push rod is in the retracted state, the interference plate is in the position area away from the opposed photoelectric sensor.

[0014] The present invention provides a turning device for thin film edge trimming and recycling, which has the following beneficial effects: By firmly clamping the Teflon film blank between two annular clamping plates a and firmly clamping the winding sleeve between two annular clamping b, the present invention ensures the stability during the film turning and winding processes. At the same time, the motor a drives the Teflon film blank to rotate at a high speed, and the electric cylinder pushes the turning tool to cooperate for turning. Combined with the auxiliary conveying of the film by three conveying rollers, the efficient turning and smooth conveying of the film are realized, ensuring the quality and efficiency of the turning processing.

[0015] The slitting tool of the present invention is fixedly installed on the slider of the slide rail assembly d. It can flexibly adjust the position of the slider on the slide rail assembly d according to the actual situation such as the width of the film, and then accurately adjust the position of the slitting tool, so as to accurately cut off the edges of both sides of the film, improving the quality of the film product.

[0016] The opposed photoelectric sensor of the present invention is cooperatively installed on the slide rail assembly b, and its position can be adjusted according to the width of the film to ensure that it can be moved to the edge position of the film to monitor this position. When the position deviation of the film causes the change in the intensity of the optical signal to reach the set threshold value, the control box controls the warning light belt to start immediately, timely reminding the staff to make adjustments, effectively avoiding the processing problems caused by the film deviation, and ensuring the normal progress of the film processing.

[0017] The fault determination timing modules a and b inside the control box of the present invention cooperate with the electric push rod and the interference plate to achieve the fault detection of the transmissive photoelectric sensor. When the timing value of the fault determination timing module a is reached, the electric push rod extends to make the interference plate interfere with the optical path. If the optical signal received by the transmissive photoelectric sensor reaches the specified threshold, the warning light strip is activated to indicate that there may be a fault. This not only reminds the staff to actually go to observe the situation of the film to check for potential problems, but also can detect and judge whether the transmissive photoelectric sensor fails to ensure that the transmissive photoelectric sensor is in a normal operating state, guaranteeing that when the film is offset, a warning can be given in the first time. When the timing value of the fault determination timing module b is reached, the electric push rod is retracted to make the sensor return to the normal detection state, and at the same time, the fault determination timing module a is controlled to re-time, realizing a cyclic detection and determination operation, ensuring the reliability and stability of the equipment detection system, and providing a strong guarantee for the continuous and stable operation of film processing.

The side mounting plate 202 is located at the rear side of the middle region between the two sets of slide rail assemblies a204. On the right end face of the side mounting plate 202, a set of electric cylinders 203 is fixedly installed.

On the top surface of the body 1, two mounting blocks b3 are fixedly installed in a front-back symmetric manner. The mounting blocks b3 are located in the middle region between the electric cylinder 203 and the slide rail assemblies b4.

[0023] In an embodiment of the present invention, a control box 101 is installed on the front end face of the machine body 1. The control box 101 is electrically connected to a motor a 104, an electric cylinder 203, an opposed photoelectric sensor 402, an electric push rod 501, and a motor b 701. A warning light strip 102 is installed around the outer end face of the machine body 1, and the warning light strip 102 is electrically connected to the control box 101. Inside the control box 101, there are a fault determination timing module a 108 and a fault determination timing module b 109 that are electrically connected to it. The timing value of the fault determination timing module a 108 is five minutes, and the timing value of the fault determination timing module b 109 is five seconds. When the timing value of the fault determination timing module a 108 is reached, the fault determination timing module a 108 feeds back a signal to the control box 101, and the control box 101 controls the push rod end of the electric push rod 501 to extend and controls the start of timing of the fault determination timing module b 109. When the push rod end of the electric push rod 501 is fully extended, at this time, the interference plate 503 is in the optical path position between the transmitting end and the receiving end of the opposed photoelectric sensor 402, interfering with the light beam emitted by the transmitting end, so that the intensity of the optical signal received by the opposed photoelectric sensor 402 decreases, thereby triggering the threshold value set by the opposed photoelectric sensor 402. When the optical signal received by the opposed photoelectric sensor 402 reaches its specified threshold value, it feeds back a signal to the control box 101, and the control box 101 controls the warning light strip 102 to start. When the timing value of the fault determination timing module b 109 is reached, the fault determination timing module b 109 feeds back a signal to the control box 101, and the control box 101 controls the push rod end of the electric push rod 501 to retract and controls the start of timing of the fault determination timing module a 108. When the push rod end of the electric push rod 501 is in the retracted state, the interference plate 503 is in the position area away from the opposed photoelectric sensor 402.

[0024] The working principle of this embodiment: First, insert the polytetrafluoroethylene film embryo to be turned on the screw a 105 so that it is between the two annular clamping plates a 107, and then rotate the two nuts a 106 along the screw a 105 thread to press against the two annular clamping plates a 107, thereby firmly clamping the polytetrafluoroethylene film embryo between the two annular clamping plates a 107. The push rod end of the electric cylinder 203 pushes the supporting block 2 to move on the two sets of slide rail assemblies a 204, thereby adjusting the position of the turning tool 201 to align it with the polytetrafluoroethylene film embryo to prepare for turning. The winding sleeve 705 for film winding is inserted on the screw b 702 so that it is between the two annular clamps b 704, and then rotate the two nuts b 703 along the screw b 702 thread to press against the two annular clamps b 704, thereby firmly clamping the winding sleeve 705 between the two annular clamps b 704. The starting motor a104 drives the screw a105 to rotate, so as to synchronously drive the Teflon film embryo to rotate at a high speed. At the same time, the electric cylinder 203 pushes the supporting block 2, so that the turning tool 201 turns the Teflon film embryo to cut out the required film. The cut film is assisted in conveying by three conveying rollers 301. The conveying rollers 301 play a role in supporting and guiding the film, enabling the film to be conveyed forward smoothly. When the film reaches the winding sleeve 705, the motor b701 drives the screw b702 to rotate, thereby synchronously driving the winding sleeve 705 to rotate to realize the winding of the film; During the conveying process of the film, when it reaches the position of the slitting knife 601 located on the slide rail assembly d6, the slitting knife 601 will cut off the burrs on both sides of the film. The slitting knife 601 is fixedly installed on the slider of the slide rail assembly d6. According to the actual situation such as the width of the film, the position of the slitting knife 601 can be adjusted by adjusting the position of the slider on the slide rail assembly d6 to achieve accurate burr cutting; According to the actual situation such as the width of the film, the position of the transmissive photoelectric sensor 402 is adjusted by adjusting the position of the slider on the slide rail assembly b4, so that the edge part of the film is in the optical path position between the transmitting end and the receiving end of the transmissive photoelectric sensor 402, and a threshold value is set according to the intensity of the optical signal received at this position; when the film is displaced, the intensity of the optical signal received will increase or decrease, reaching the set threshold value, and its feedback signal is given to the control box 101. The control box 101 controls the warning light strip 102 to start, so as to remind the staff through the warning light of the warning light strip 102 that the film is displaced at present and needs to be readjusted in time; The timing value of the fault determination timing module a108 inside the control box 101 is five minutes. When the timing value of the fault determination timing module a108 is reached, the fault determination timing module a108 gives a feedback signal to the control box 101. The control box 101 controls the push rod end of the electric push rod 501 to extend and controls the start of the timing of the fault determination timing module b109; When the push rod end of the electric push rod 501 is fully extended, the interference plate 503 is in the optical path position between the transmitting end and the receiving end of the opposed photoelectric sensor 402, interfering with the light beam emitted by the transmitting end and causing the intensity of the optical signal received by the opposed photoelectric sensor 402 to decrease. After the interference, the optical signal received by the opposed photoelectric sensor 402 reaches its specified threshold value. At this time, it gives a feedback signal to the control box 101, and the control box 101 controls the warning light strip 102 to start, indicating that there may be a fault. Through this design, on the one hand, it can remind the staff to approach and actually observe the specific situation of the film to discover potential problems that may exist. On the other hand, the opposed photoelectric sensor 402 is detected and judged to check whether it has a malfunction, ensuring that the opposed photoelectric sensor 402 is in a normal operating state. In this way, it can be ensured that when the film is displaced, through the monitoring of the opposed photoelectric sensor 402, the warning light strip 102 can give a warning reminder in the first time, greatly improving the reliability of the system and the fault warning ability, and ensuring the stable operation of the entire device; When the timing value (five seconds) of the fault determination timing module b109 is reached, the fault determination timing module b109 gives a feedback signal to the control box 101. The control box 101 controls the push rod end of the electric push rod 501 to retract and controls the start of timing of the fault determination timing module a108. When the push rod end of the electric push rod 501 is in the retracted state, the interference plate 503 is in the position area far from the opposed photoelectric sensor 402, and the opposed photoelectric sensor 402 resumes the normal detection state, preparing for the next fault detection and realizing the cyclic detection and determination operation.
