[0024] When the extrusion speed of the rubber strip extrusion equipment is faster than the winding speed of the rubber strip winding equipment, the rubber strip at the pulley is slack and disengages from the pulley. The pulley seat moves in the direction of the slack rubber strip under the action of the air pressure. After the displacement sensor detects the movement of the pulley seat, it transmits a signal to the rubber strip winding equipment. When the moving distance of the pulley seat exceeds the allowable displacement value of the pulley seat, the winding disc accelerates until the position of the pulley seat returns to the set position. When the extrusion speed of the rubber strip extrusion equipment is slower than the winding speed of the rubber strip winding equipment, the rubber strip at the pulley is tightened and pushes the pulley seat in the opposite direction.

[0040] Embodiment 1

[0041] As Figure 2 shown, Figure 2 This is a schematic structural diagram of the speed detection station of an automatic rubber strip winding detection device according to Embodiment 1 of the present invention. In this embodiment, the pulley mounting mechanism includes a rod 3, a fixed bracket 4 and a slider 5. The fixed bracket 4 is fixedly arranged between the rubber strip extrusion device and the rubber strip winding device. The middle part of the rod 3 is hinged to the fixed bracket 4. One end of the rod 3 is connected with a pulley 2, and the other end of the rod 3 is movably mounted with a slider 5. The slider 5 and the pulley 2 are on both sides of the hinge point; the pulley position change detection device is an angle sensor for detecting the rotation angle of the rod 3 around the hinge point.

[0042] Adaptive adjustment method for the winding speed of rubber strips: The pulley mounting mechanism includes a rod 3, a fixed bracket 4, and a slider 5. The fixed bracket 4 is fixedly arranged between the rubber strip extrusion device and the rubber strip winding device. The middle part of the rod 3 is hinged to the fixed bracket 4. At one end of the rod 3, a pulley 2 is connected. At the other end of the rod 3, a slider 5 is adjustably mounted. The slider 5 and the pulley 2 are on both sides of the hinge point. The pulley position change detection device is an angle sensor for detecting the rotation angle of the rod 3 around the hinge point.

[0043] The rubber strip 1 extruded by the rubber strip extrusion device enters the rubber strip winding device after passing through the speed detection station. Set the set angle of the rod 3. At the set angle, the pulley 2 contacts the rubber strip 1 under the action of gravity. Those of ordinary skill in the art should understand that in this state, the pulley 2 should press the rubber strip 1 tightly to a certain degree of tension. The specific tension value should be obtained through experiments in combination with the parameters of the rubber strip 1 itself. Since this value is not the core innovation point of the present invention, it will not be introduced separately herein. When the pulley 2 is at the set angle position of the rod 3, the extrusion speed of the rubber strip extrusion device is the same as the winding speed of the rubber strip winding device. When the extrusion speed of the rubber strip extrusion device is faster than the winding speed of the rubber strip winding device, the rubber strip 1 at the pulley 2 becomes loose and detaches from the pulley 2. The rod 3 rotates under the action of the gravity of the pulley 2. After the angle sensor detects the rotation of the rod 3, it transmits a signal to the rubber strip winding device. When the rotation angle of the rod 3 exceeds the allowable value of the rod angle, the winding disc accelerates until the rotation of the rod 3 resumes to the set angle. When the extrusion speed of the rubber strip extrusion device is slower than the winding speed of the rubber strip winding device, the rubber strip at the pulley is tightened and the rod 3 is rotated in the opposite direction. After the angle sensor detects the rotation of the rod 3, it transmits a signal to the rubber strip winding device. When the rotation angle of the rod 3 exceeds the allowable value of the rod angle, the winding disc decelerates until the rotation of the rod 3 resumes to the set angle.

[0044] By adjusting the position of the slider 5 on the rod 3, the force for the pulley 2 to rotate under the action of gravity is adjusted.

[0045] Example 2

[0046] In Example 1, since the movement mode of the rod 3 is rotation, its stability is relatively poor. The self-vibration of the rubber strip 1 during the winding process may affect the state of the rod 3. Therefore, on the basis of Example 1, its structure is improved, and the pulley 2 is arranged on a relatively stable pulley seat 6.

[0047] As Figure 3 shown, Figure 3This is a schematic structural diagram of the speed detection station of an automatic tape winding detection device according to Embodiment 2 of the present invention. The pulley mounting mechanism includes a pulley seat 6, a guide rod 7, a spring 8, and a mounting seat 10. The mounting seat 10 is fixedly arranged between the tape extrusion device and the tape winding device. The guide rod 7 is installed on the mounting seat 10 so as to be linearly movable up and down. The lower end of the guide rod 7 is connected to the pulley seat 6, and a pulley 2 is installed at the lower end of the pulley seat 6. A spring 8 that always provides an elastic force in the downward direction to the guide rod 7 is arranged between the guide rod 7 and the mounting seat 10; the pulley position change detection device is a displacement sensor 9 arranged on the mounting seat 10, and the displacement sensor 9 detects the up and down position change of the guide rod 7.

[0048] Tape winding speed adaptive adjustment method: The pulley mounting mechanism includes a pulley seat 6, a guide rod 7, a spring 8, and a mounting seat 10. The mounting seat 10 is fixedly arranged between the tape extrusion device and the tape winding device. The guide rod 7 is installed on the mounting seat 10 so as to be linearly movable up and down. The lower end of the guide rod 7 is connected to the pulley seat 6, and a pulley 2 is installed at the lower end of the pulley seat 6. A spring 8 that always provides an elastic force in the downward direction to the guide rod 7 is arranged between the guide rod 7 and the mounting seat 10; the pulley position change detection device is a displacement sensor 9 arranged on the mounting seat 10, and the displacement sensor 9 detects the up and down position change of the guide rod 7;

[0049] The tape extruded by the tape extrusion device enters the tape winding device after passing through the speed detection station. Set the set position of the pulley seat 6. At the set position, the pulley 2 contacts the tape 1. When the extrusion speed of the tape extrusion device is faster than the winding speed of the tape winding device, the tape 1 at the pulley 2 becomes loose and detaches from the pulley. The pulley seat 6 moves in the direction of tape relaxation under the action of the spring 8. The displacement sensor 9 transmits the movement signal of the pulley seat 6 to the tape winding device. When the moving distance of the pulley seat 6 exceeds the allowable pulley seat displacement value, the winding disc accelerates until the position of the pulley seat 6 returns to the set position. When the extrusion speed of the tape extrusion device is slower than the winding speed of the tape winding device, the tape at the pulley tightens and pushes the pulley seat in the opposite direction. The displacement sensor 9 transmits the movement signal of the pulley seat 6 to the tape winding device. When the moving distance of the pulley seat 6 exceeds the allowable pulley seat displacement value, the winding disc decelerates until the position of the pulley seat 6 returns to the set position.

[0050] This embodiment solves the stability problem of the pulley 2. However, since the elastic force of the spring 8 is variable, the force exerted on the tape 1 at different positions of the pulley seat 6 is different, which to some extent limits the application range of the device.

[0051] Embodiment 3

[0052] This embodiment is improved on the basis of Embodiment 2, as Figure 4 shown, Figure 4Schematic diagram of the speed detection station of an automatic tape winding detection device according to Embodiment 3 of the present invention. In this embodiment, the pulley mounting mechanism includes a mounting base 10, a piston rod 11, and a cylinder 12. The mounting base 10 is fixedly arranged between the tape extrusion device and the tape winding device. The cylinder 12 is fixed on the mounting base 10. The piston of the piston rod 11 is installed in the cylinder 12. The lower end of the piston rod 11 is connected with a pulley seat 6. The lower end of the pulley seat 6 is installed with a pulley 2. Three parallel pipelines are connected to the upper and lower bottoms of the inner cavity of the cylinder 12. The first pipeline is communicated with the compressed air source. A pressure reducing valve 13 is arranged on the first pipeline. The second pipeline is connected with a silencer 14. A solenoid valve 15 is arranged on the second pipeline. The third pipeline is connected with a pressure sensor 16. The pulley position change detection device is a displacement sensor 9 arranged on the mounting base 10. The displacement sensor 9 detects the up and down position change of the piston rod 11. The pressure reducing valve 13 is used to set the air pressure entering the cylinder 12 in the first pipeline. The solenoid valve 15 is an electromagnetic control on-off valve. The pressure sensor 16 is used to detect the air pressure in the inner cavity of the cylinder 12. When the air pressure in the inner cavity of the cylinder 12 exceeds the set value of the pressure reducing valve 13, the solenoid valve 15 is controlled to connect the pipeline, and the pressure is relieved through the silencer 14 until the air pressure drops to the set value.

[0053] A method for adaptively adjusting the tape winding speed: The pulley mounting mechanism includes a mounting base 10, a piston rod 11, and a cylinder 12. The mounting base 10 is fixedly arranged between the tape extrusion device and the tape winding device. The cylinder 12 is fixed on the mounting base 10. The piston of the piston rod 11 is installed in the cylinder 12. The lower end of the piston rod 11 is connected with a pulley seat 6. The lower end of the pulley seat 6 is installed with a pulley 2. Three parallel pipelines are connected to the upper and lower bottoms of the inner cavity of the cylinder 12. The first pipeline is communicated with the compressed air source. A pressure reducing valve 13 is arranged on the first pipeline. The second pipeline is connected with a silencer 14. A solenoid valve 15 is arranged on the second pipeline. The third pipeline is connected with a pressure sensor 16. The pulley position change detection device is a displacement sensor 9 arranged on the mounting base 10. The displacement sensor 9 detects the up and down position change of the piston rod 11.

[0054] The tape extruded by the tape extrusion device enters the tape winding device after passing through the speed detection station. Set the set position of the pulley seat 6. At the set position, the pulley 2 contacts the tape 1. Set the air pressure in the upper part of the inner cavity of the cylinder 12 to be greater than the air pressure in the lower part, and the upper and lower air pressure difference is a fixed value.

[0055] When the extrusion speed of the rubber strip extrusion equipment is faster than the winding speed of the rubber strip winding equipment, the rubber strip 1 at the pulley 2 relaxes and detaches from the pulley, and the pulley seat 6 moves in the direction of the rubber strip relaxation under the action of air pressure. The displacement sensor 9 detects the movement of the pulley seat 6 and transmits a signal to the rubber strip winding equipment. When the moving distance of the pulley seat 6 exceeds the allowable displacement value of the pulley seat, the winding disk accelerates until the position of the pulley seat 6 returns to the set position. When the extrusion speed of the rubber strip extrusion equipment is slower than the winding speed of the rubber strip winding equipment, the rubber strip at the pulley is tightened and pushes the pulley seat in the opposite direction. After the displacement sensor 9 detects the movement of the pulley seat 6, it transmits a signal to the rubber strip winding equipment. When the moving distance of the pulley seat 6 exceeds the allowable displacement value of the pulley seat, the winding disk decelerates until the position of the pulley seat returns to the set position.

[0056] Since the pressure difference between the upper and lower chambers of the cylinder 12 is a fixed value, the force with which the pulley 2 presses the rubber strip 1 to tighten it is constant.

[0057] The automatic rubber strip winding detection device can realize the automatic winding, thickness and incoming speed detection of the rubber strip. The thickness detection result can be fed back to the previous process in real time, which is convenient for the previous extrusion process to automatically adjust the process parameters and improve the product yield. The incoming speed detection can realize unattended operation, and the winding effect exceeds manual winding in consistency and orderliness. The device can operate unattended for 3 hours continuously, with a winding length of more than 600 meters at a time. The production efficiency is several times higher than that of the traditional semi-automatic winding method.

When the extrusion speed of the rubber strip extrusion equipment is slower than the winding speed of the rubber strip winding equipment, the rubber strip at the pulley is tightened and pushes the pulley seat in the opposite direction. The displacement sensor transmits the movement signal of the pulley seat to the rubber strip winding equipment. When the moving distance of the pulley seat exceeds the allowable value of the pulley seat displacement, the winding disc decelerates until the position of the pulley seat returns to the set position.

4. A method for adaptively adjusting the winding speed of a rubber strip according to claim 1, characterized in that The pulley installation mechanism includes a mounting seat, a piston rod, and a cylinder. The mounting seat is fixedly arranged between the rubber strip extrusion equipment and the rubber strip winding equipment. The cylinder is fixed on the mounting seat. The piston of the piston rod is installed in the cylinder. The lower end of the piston rod is connected with a pulley seat, and a pulley is installed at the lower end of the pulley seat. Three parallel pipelines are connected to the upper and lower bottoms of the inner cavity of the cylinder. The first pipeline is communicated with the compressed air source, and a pressure reducing valve is arranged on the first pipeline. The second pipeline is connected with a silencer, and a solenoid valve is arranged on the second pipeline. The third pipeline is connected with a pressure sensor; the pulley position change detection device is a displacement sensor arranged on the mounting seat, and the displacement sensor detects the up and down position change of the piston rod; The rubber strip extruded by the rubber strip extrusion equipment enters the rubber strip winding equipment after passing through the speed detection station. Set the set position of the pulley seat. At the set position, the pulley contacts the rubber strip. Set the air pressure in the upper part of the inner cavity of the cylinder to be greater than the air pressure in the lower part, and the upper and lower air pressure difference is a fixed value; When the extrusion speed of the rubber strip extrusion equipment is faster than the winding speed of the rubber strip winding equipment, the rubber strip at the pulley is slack and detached from the pulley. The pulley seat moves in the direction of the slack of the rubber strip under the action of the air pressure. After the displacement sensor detects the movement of the pulley seat, it transmits a signal to the rubber strip winding equipment. When the moving distance of the pulley seat exceeds the allowable value of the pulley seat displacement, the winding disc accelerates until the position of the pulley seat returns to the set position. When the extrusion speed of the rubber strip extrusion equipment is slower than the winding speed of the rubber strip winding equipment, the rubber strip at the pulley is tightened and pushes the pulley seat in the opposite direction. After the displacement sensor detects the movement of the pulley seat, it transmits a signal to the rubber strip winding equipment. When the moving distance of the pulley seat exceeds the allowable value of the pulley seat displacement, the winding disc decelerates until the position of the pulley seat returns to the set position.
