[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0057] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly or indirectly attached to that other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to that other component. The terms "upper," "lower," "left," "right," etc., indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, and are for ease of description only, not to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0058] It should be noted that during the actual winding process of material 500, a predetermined linear speed needs to be maintained. It is understood that material 500 has a certain degree of elasticity. If the actual winding speed is too fast, it will cause material 500 to be stretched and deformed. When the actual winding speed is too slow, it cannot provide sufficient traction, resulting in material 500 being wound loosely.

[0059] Please see Figure 1 and Figure 5 In a first aspect, embodiments of the present invention provide an aerogel speed-measuring winding device for winding material 500.

[0060] The aerogel speed measuring and winding device includes: a support component 100, a winding component 200, a speed measuring component 300, and a control component 400.

[0061] The support assembly 100 serves as a mounting carrier for other components. For example, the support assembly 100 can be a support frame or a support cabinet. The support assembly 100 can be made of stainless steel, providing high structural strength.

[0062] The winding assembly 200 includes a drive member 210 and a winding shaft 220 connected to the drive member 210. The winding shaft 220 is rotatably disposed on the support assembly 100. The drive member 210 can drive the winding shaft 220 to rotate relative to the support assembly 100, thereby winding the material 500 onto the winding shaft 220. Finally, the winding shaft 220 is removed from the support assembly 100 to obtain the wound material 500.

[0063] It should be noted that the output shaft of the drive component 210 and the winding shaft 220 can be directly connected using a coupling, or the drive component 210 and the winding shaft 220 can be connected using a reducer. The specific configuration can be made according to the specific circumstances, and the present invention does not impose any restrictions.

[0064] The speed measuring component 300 abuts against the material 500 wound on the winding shaft 220 and is used to obtain the actual winding linear speed of the material 500. The speed measuring component 300 can be set on the side of the winding shaft 220 and abut against the material 500 on the winding shaft. Taking the point of contact between the speed measuring component 300 and the winding shaft 220 before winding the material 500 as the origin and the point of contact between the speed measuring component 300 and the material 500 after winding as the end point, and taking the winding shaft as the reference axis, perpendicular lines are drawn from the origin on the winding shaft and from the end point on the winding shaft, respectively. The lengths of the two perpendicular lines are measured, and the absolute value of the difference between the two perpendicular lines is taken to obtain the change in the winding diameter, thereby obtaining the winding diameter of the material 500.

[0065] The control component 400 is electrically connected to the speed measuring device and the winding component 200, and is used to control the rotational speed of the drive component 210.

[0066] It is understandable that a suitable predetermined linear speed can be established by actually measuring the tensile strength of the material 500. The predetermined linear speed will adapt to different materials 500. When the actual winding linear speed measured by the speed measuring component 300 is less than the predetermined linear speed, the control component 400 controls the drive component 210 to increase the rotational speed, thereby achieving the predetermined linear speed. When the actual winding linear speed measured by the speed measuring component 300 is greater than the predetermined linear speed, the control component 400 controls the drive component 210 to decrease the rotational speed, thereby achieving the predetermined linear speed.

[0067] The aerogel speed measuring and winding device of the present invention can realize automatic adjustment of the actual winding line speed, has high reliability, and the winding diameter can be measured, thereby ensuring deviation, saving materials and time, while ensuring that the winding force of the material 500 is moderate, the wound material 500 is not easily deformed, and the yield of the wound product is high.

[0068] Please see Figure 1-2 In one embodiment, the speed measuring component 300 includes a speed measuring rod 310 and a sensor 320. One end of the speed measuring rod 310 is hinged to the support component 100, and the other end of the speed measuring rod 310 abuts against the material 500 on the winding shaft 220. The sensor 320 is used to measure the winding diameter of the material 500 and obtain the actual winding linear speed based on the winding diameter.

[0069] When the winding shaft 220 winds the material 500, the speed measuring rod 310 abuts against the side of the material 500 on the winding shaft 220. As the winding diameter of the material 500 gradually changes, the speed measuring rod 310 rotates around the hinge point with the support assembly 100 (rotating away from the winding shaft 220). At this time, the position change of the speed measuring rod 310 can be measured by the sensor 320, and the current winding diameter can be obtained from the position change, improving the convenience of obtaining the winding diameter.

[0070] The sensor 320 includes a drawstring 322 and a sensing element 321. One end of the drawstring 322 is connected to a speed measuring rod 310, and the other end is retractably connected to the sensing element 321. The speed measuring rod 310 can cause the drawstring 322 to extend or retract relative to the sensing element 321. The sensing element 321 is used to measure the change in length of the drawstring 322, thereby calculating the winding diameter. Preferably, the drawstring 322 is connected to the end of the speed measuring rod 310 near the winding shaft, which allows for more accurate measurement of the position change of the speed measuring rod 310. As an example, the sensor 320 can be a drawstring 322 sensor, with the drawstring 322 fixed to the speed measuring rod 310. As material 500 gradually accumulates on the winding shaft 220, the speed measuring rod 310 rotates around the support assembly 100, causing a change in the length of the drawstring 322 of the drawstring 322 sensor. The winding diameter can be obtained by measuring the change in the length of the drawstring 322 of the drawstring 322 sensor.

[0071] In some other embodiments, the speed measuring component 300 can be a transmissive projector, infrared sensor, laser sensor, etc., mounted on the support component 100, which measures the winding diameter of the winding shaft 220 in real time.

[0072] In some instances, control component 400 may include a control panel 210 electrically connected to the drive and sensor 320, and the control panel may display changes in the current winding diameter and the actual winding linear speed.

[0073] Please see Figure 2 The speed measuring component 300 also includes a telescopic rod 330, one end of which is hinged to the support component 100, and the other end of which is hinged to the speed measuring rod 310. Exemplarily, the telescopic rod 330 includes a main rod 331 and a sub-rod 332. The sub-rod 332 is telescopically connected to the main rod 331 and can move relative to the main rod 331 under external force. The end of the main rod 331 away from the sub-rod 332 is hinged to the support component 100, and the end of the sub-rod 332 away from the main rod 331 is hinged to the speed measuring rod 310. In this embodiment, the sub-rod 332 is partially housed within the main rod 331. An elastic element that abuts against the sub-rod 332 is provided within the main rod 331. When the sub-rod 332 is subjected to external force, it retracts into the main rod 331, thereby compressing the elastic element. After the external force is removed, the elastic element recovers its deformation, causing the sub-rod 332 to extend outward from the main rod 331 and return to its original position. The telescopic rod 330, the speed measuring rod 310, and part of the support assembly 100 together form a triangle. The telescopic rod 330 supports the speed measuring rod 310, reduces the vibration of the speed measuring rod 310, and thus improves the accuracy of the winding diameter measurement.

[0074] In some examples, the main rod 331 has a certain damping, and the sub-rod 332 needs to be subjected to a certain force to slide relative to the main rod 331, thereby reducing the vibration amplitude of the speed measuring rod 310 and further improving the accuracy of the winding diameter measurement.

[0075] Please see Figure 2 In one embodiment, a caster wheel 340 is rotatably connected to one end of the speed measuring rod 310 near the winding shaft 220, and the caster wheel 340 abuts against the material 500 on the winding shaft 220. It can be understood that when the material 500 is wound up, the caster wheel 340 rolls on the surface of the material 500, thereby reducing the damage to the material 500 during winding.

[0076] Please see Figure 2 The support assembly 100 is provided with a pad 110, a first hinge seat 120, and a second hinge seat 130. The pad 110 is disposed on the support assembly 100, and the first hinge seat 120 and the second hinge seat 130 are respectively disposed on the pad 110. The pad 110 has a predetermined thickness and is used to elevate the first hinge seat 120 and the second hinge seat 130. The first hinge seat 120 and the second hinge seat 130 are spaced apart, and the first hinge seat 120 is disposed on the side of the second hinge seat 130 away from the winding assembly 200. The speed measuring rod 310 is hinged to the first hinge seat 120, and the telescopic rod 330 is hinged to the second hinge seat 130. It is understood that in some other embodiments, the pad 110 may be omitted, and the first hinge seat 120 and the second hinge seat 130 may be directly disposed on the support assembly 100.

[0077] Please see Figure 1 In one embodiment, in order to maintain the neatness of the end face of the wound material 500, baffles 230 are provided at both ends of the winding shaft 220. The distance between the two baffles 230 is greater than or equal to the width of the material 500. During the winding process of the material 500, the material 500 is always between the baffles 230.

[0078] Please see Figure 1 and Figure 3 In one embodiment, in order to fix the sensor 320, the support assembly 100 is further provided with a mounting base 140, on which the sensor 320 is mounted.

[0079] Mounting base 140 includes a first substrate 150 and a second substrate 160, which are staggered. The first substrate 150 is used to connect to the sensor 320, and the second substrate 160 is used to connect to the support assembly 100. By adjusting the mounting position of the second substrate 160 on the support assembly 100, the relative position between the sensor 320 and the support assembly 200 can be adjusted.

[0080] Please see Figure 3In one embodiment, a position adjustment groove 170 is provided on the first substrate 150, and the position adjustment groove 170 is provided along the width direction of the first substrate 160. The sensor 320 is disposed in the position adjustment groove 170, and the sensor 320 can slide within the position adjustment groove 170 along the width direction, thereby adjusting the position of the sensor 320. The width direction is the same as the axial direction of the winding shaft 210.

[0081] Please see Figure 4 Secondly, the present invention also proposes a speed-measuring winding method, comprising the following steps:

[0082] S1. The material 500 is wound up by the winding assembly 200;

[0083] S2. Obtain the actual winding speed of material 500 through the speed measuring component 300;

[0084] S3, Control component 400 adjusts the actual winding speed according to the predetermined linear speed.

[0085] Since this speed measurement and winding method adopts all the technical solutions of all embodiments of the above-mentioned aerogel speed measurement and winding device, it also has all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0086] The steps for obtaining the actual winding speed of material 500 using the speed measuring component 300 include:

[0087] S21, Speed ​​measuring component 300 measures the winding diameter of material 500;

[0088] S22, The control component 400 obtains the actual winding speed of the winding component 200;

[0089] S23. The actual winding linear speed of material 500 is calculated by using the winding diameter of material 500 and the actual winding speed of winding assembly 200.

[0090] The speed measuring component 300 includes a speed measuring rod 310 and a sensor 320. The step of the speed measuring component 300 measuring the winding diameter of the material 500 includes:

[0091] The speed measuring component 300 includes a speed measuring rod 310 and a sensor 320. The steps of the speed measuring component 300 in measuring the winding diameter of the material 500 include:

[0092] S211, the contact point between the speed measuring rod 310 and the winding shaft is the initial contact point C, and the diameter of the winding shaft is the initial diameter;

[0093] S212, the speed measuring rod 310 abuts against the material 500 on the winding shaft of the winding assembly 200, and the contact point between the speed measuring rod 310 and the material 500 on the winding shaft is the actual contact point C1;

[0094] S213, sensor 320 measures the change in distance between the initial contact point C and the actual contact point C1, and calculates the winding diameter using the initial diameter and displacement distance.

[0095] Specifically, when the winding assembly 200 is not winding the material 500, the speed measuring rod of the speed measuring assembly 300 abuts against the winding shaft 220. Taking the winding shaft 220 as the reference axis, the abutment point between the speed measuring rod 310 and the winding shaft 220 is the initial abutment point C. After the winding assembly 200 winds up the material 500, the speed measuring rod of the speed measuring assembly 300 abuts against the material 500 on the winding shaft 220. The abutment point between the speed measuring rod and the material 500 on the winding shaft 220 is the actual abutment point C1. The sensor 320 can measure the lengths of the two perpendicular lines and take the absolute value of the difference between the two perpendicular lines to obtain the change distance between the initial abutment point C and the actual abutment point C1. This change distance is the change in the winding diameter of the material 500. Then, the winding diameter of the material 500 can be obtained by using this change and the initial diameter.

[0096] In an embodiment of the present invention that utilizes a wire 322 sensor to obtain the winding diameter, such as Figure 5 As shown, as an example of obtaining the actual winding speed of material 500 through speed measuring component 300, one end of the pull wire 322 of sensor 320 is connected to the end of speed measuring rod 310 that abuts against the winding component 200. In actual setup, the contact point (initial contact point C or actual contact point C1) between speed measuring rod 310 and winding component 200 and the end of pull wire 322 away from sensing element 321 may not coincide. For ease of calculation, the distance between the contact point between speed measuring rod 310 and winding component 200 and the end of pull wire 322 away from sensing element 321 can be ignored, that is, it is assumed that the initial contact point C or actual contact point C1 is also the end of pull wire 322 away from sensing element 321.

[0097] Specifically, point O is the hinge point between the speed measuring rod 310 and the support assembly 100, point A is the mounting point of the sensing element 321 of the sensor 320 on the support assembly 100, point C is the initial contact point between the speed measuring rod 310 and the winding shaft 220, point B is the perpendicular foot of point C on the support assembly 100, point C1 is the actual contact point between the speed measuring rod 310 and the material 500 on the winding shaft 220, and point B1 is the perpendicular foot of point C1 on the support assembly 100; the distance between points A and C, and the distance between points A and C1, can be measured by the length of the pull wire 322 of the sensor 320, the distance between points A and O can be measured, and the distance between points O and C, and the distance between points O and C1, are all the rod length of the speed measuring rod 310.

[0098] When the winding assembly 200 is not winding the material 500, the speed measuring rod of the speed measuring assembly 300 abuts against the winding shaft 220 at the initial contact point C. In the triangle OAC formed by the speed measuring rod 310, the pull wire 322, and the support assembly 100, the lengths of the three sides can be determined by measurement, and the size of the first included angle ∠COA can be calculated according to the law of cosines. After the winding assembly 200 winds the material 500, the speed measuring rod 310 abuts against the material 500 at the actual contact point C1. Similarly, in the triangle OAC1 formed by the speed measuring rod 310, the pull wire 322, and the support assembly 100, the size of the second included angle ∠C1OA can be calculated according to the law of cosines. In triangle 0CB, given the size of the included angle ∠COB (i.e., the first included angle ∠COA) and the side length of line segment OC (the length of the speed measuring rod), the length of line segment BC can be calculated. Similarly, in triangle 0C1B, given the size of the included angle ∠C1OB1 (i.e., the first included angle ∠C1OA) and the side length of line segment B1C1 (the length of the speed measuring rod), during the winding process of the winding assembly 200 winding the material 500, the distance that point B moves to point B1 is very small and can be ignored. The length of BC minus the length of B1C1 is approximately equal to the length of CC1, which is the winding radius of the material 500. Calculation yields the winding diameter of the speed measuring rod 310 at the actual contact point.

[0099] The steps for calculating the actual winding linear speed of material 500 using the winding diameter of material 500 and the actual winding speed of winding assembly 200 include:

[0100] S231, the control component 400 can obtain the actual winding speed of the current winding component 200 (the rotation speed of the winding shaft 220);

[0101] S232. The winding angular velocity of the winding assembly 200 is calculated based on the actual winding speed.

[0102] S233. The current actual winding linear speed is calculated by using the winding angular velocity and winding diameter;

[0103] The calculation formula is as follows:

[0104] w = 2πn;

[0105] v = wd / 2;

[0106] Where n is the actual winding speed of the winding assembly 200, w is the winding angular velocity of the winding assembly 200, v is the actual winding linear velocity, and d is the winding diameter of the material 500.

[0107] The step of the control component 400 adjusting the actual winding speed according to the predetermined linear speed includes:

[0108] S31. Subtract the actual winding speed from the predetermined linear speed to obtain the linear speed difference;

[0109] S32. The first compensated winding speed is calculated based on the linear speed difference and the winding diameter;

[0110] S33. The sum of the actual winding speed and the first compensated winding speed is used to adjust the winding speed;

[0111] S34, Control component 400 controls winding component 200 to adjust winding speed to wind material 500.

[0112] It is understandable that the difference in linear speed can be positive or negative, and its sign represents the magnitude relationship between the actual winding linear speed and the predetermined linear speed.

[0113] Since the actual winding speed is inconvenient to adjust directly, this embodiment converts the actual winding speed into a first compensated winding speed for adjustment.

[0114] In one embodiment, the speed measurement and winding method further includes:

[0115] S41, The control component 400 obtains the actual torque of the drive component 210 of the winding component 200;

[0116] S42. The torque compensation difference is obtained by subtracting the actual torque from the predetermined torque.

[0117] S43. The second compensated winding speed is calculated using the torque compensation difference;

[0118] S44. The actual winding speed is adjusted by the sum of the first compensated winding speed and the second compensated winding speed.

[0119] S45, Control component 400 controls winding component 200 to adjust winding speed to wind material 500.

[0120] Specifically, the predetermined torque of the drive component 210 can be set according to the actual winding scenario, and the control component 400 can calculate the actual torque of the drive component 210. The formula for calculating the actual torque is:

[0121] X = (T + J) * 1.3;

[0122] T = 9550P / n;

[0123] Where X is the actual torque, J is the moment of inertia (constant value) of the drive component 210, P is the power of the drive component 210 (unit: KW), and n is the actual winding speed (unit: rpm).

[0124] The difference between the predetermined torque and the actual torque is the torque compensation difference. The second compensation winding speed of the drive component 210 can be calculated by reversing the above formula.

[0125] In one embodiment, the steps prior to winding up the material 500 by the winding assembly include:

[0126] S0. Determine the predetermined linear velocity based on the tensile strength of the material 500.

[0127] The predetermined linear speed can be established by measuring the tensile strength of the material 500. When the actual winding speed measured by the speed measuring component 300 is less than the predetermined linear speed, the control component 400 controls the drive component 210 to increase the rotational speed, thereby achieving the predetermined linear speed. When the actual winding speed measured by the speed measuring component 300 is greater than the predetermined linear speed, the control component 400 controls the drive component 210 to decrease the rotational speed, thereby achieving the predetermined linear speed.

[0128] As an example, when the drive unit 210 is a servo motor, the controller can control the servo motor to increase or decrease the first compensation winding speed or the second compensation winding speed. As the winding diameter of the material 500 gradually changes, the actual winding linear speed of the drive unit 210 is adaptively adjusted through the above-mentioned speed measurement winding method, ultimately achieving a dynamic balance between the actual winding linear speed and the predetermined linear speed.
