[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) Two primary distance meters are provided, and their output ends are both directed toward the woven fabric wound on the winding roller, and the two edges of the winding roller are measured. At this time, the diameter of the wound woven fabric can be measured in real time. When the diameter of the rolled fabric changes during the winding process, it means that the distance between the rolled fabric and the primary distance meter changes. The data can be sent to the controller in real time. The two primary distance meters are distributed at both ends of the winding roller and are synchronized. The controller can analyze and judge through a number of data, compare multiple places, and accurately analyze the diameter of the rolled fabric based on the data from multiple places, so as to avoid the change of the constant tension controlled by the machine due to the inaccurate calculated diameter data and the deviation from the actual value during the winding process, and avoid the uneven tension of the finished product during the winding process, thereby improving the winding effect of the machine and further reducing the limitations of the machine during use;

[0018] (2) When the limit block moves, it drives the limit arc block to move under the action of the limit slide and the limit spring, so that the limit arc blocks at the upper and lower parts of the winding roller move toward the direction of the coil. As the diameter of the coil wound on the winding roller continues to increase, the limit arc block continues to approach and contact it, thereby applying pressure and friction to the coil, clamping the winding roller, so as to limit the wound coil, avoid excessive pressure on the machine and damage caused by excessive winding diameter, thereby improving the service life of the machine and further improving the use effect of the machine. After the limit arc block contacts the coil, the limit block continues to move, causing it to move within the limit limit of the limit slide, so that the limit spring and the buffer rubber pad are in a buffering state, thereby increasing the contact strength between the limit arc block and the coil, further improving the above effect, and avoiding the phenomenon of excessive pressure on the coil caused by the buffer rubber pad, thereby reducing the limitation of the machine during use and improving the production effect of the machine.

[0019] (3) The buffering force brought by the linkage spring can reduce the impact force caused by the shaking of the winding roller during winding, thereby improving the stability of the winding roller during winding. The impact force caused by the movement of the product when the winding roller rotates acts on the machine, causing damage to the machine, reducing the limitations of the machine during use. At the same time, the diameter of the roll can be known by observing the moving distance of the linkage square column. The linkage square column moves once every time the diameter of the roll increases during winding. Therefore, the moving distance of the linkage square column can be accurately known through the controller, so that the diameter of the roll at this time can be calculated. At the same time, due to the linkage spring One end of is set on pressure sensor No. 1. When the linkage spring is squeezed and is in a buffer state, the moving distance of the linkage square column can be further known through the pressure value. It is transmitted to the controller together with the above value to further determine the winding diameter of the roll, thereby improving the accuracy of the measurement result, avoiding the deviation between the calculated winding diameter data and the actual situation, resulting in changes in the constant tension controlled by the machine, and controlling the output torque of the winding roller in real time, thereby improving the use and winding effect of the machine, and further reducing the limitations of the machine during use. At the same time, the collected multi-party data can be used by the controller to further accurately calculate the winding diameter data of the roll. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 10 As shown, the constant tension winding machine of the braiding machine of the present invention comprises a braiding machine 1; a winding roller 2 is provided on the side of the braiding machine 1, and the winding roller 2 is used to wind the braided product; winding disks 3 are installed at both ends of the winding roller 2, and a fixing base plate 4 is also installed on the side of the winding disk 3 away from the winding roller 2, and a rotating and fixed diameter measuring mechanism is provided on the fixing base plate 4, and the rotating and fixed diameter measuring mechanism is used to measure the diameter of the braided product wound by the winding roller 2; the fixing base plate 4 is arranged on the braiding machine 1; an L-shaped bracket 5 is also provided on the bottom surface of the braiding machine 1, and the end point of the L-shaped bracket 5 faces the winding roller 2 and is installed with a linkage horizontal plate 6, and a multi-dimensional evaluation component is provided on the linkage horizontal plate 6, and the multi-dimensional evaluation component is used to verify the authenticity of the data obtained by the rotating and fixed diameter measuring mechanism.

[0035] Among them, the rotating and fixed diameter measuring mechanism includes a fixing ring 7 fixedly set on the outer side walls of the two winding discs 3, the fixing ring 7 is divided into two rings, the inner diameter of the outer ring is larger than the outer diameter of the inner ring, and the outer side of the inner ring is fixed on the inner side wall of the outer ring; a controller 8 is fixedly installed on the opposite surfaces of the two fixing substrates 4; a plurality of rotating blocks 9 are slidably set on the fixing ring 7, a plurality of rotating blocks 9 are each installed with a rotating L rod 10, a plurality of rotating L rods 10 are commonly connected with a rotating block 11, and the rotating block 11 is set on the fixing substrate 4; a primary rangefinder 12 is also installed on the side of the rotating block 9 close to the winding roller 2, and the output ends of the plurality of primary rangefinders 12 are all facing the woven product wound on the winding roller 2.

[0036] After weaving, the braiding machine will wind the finished product through the winding roller 2, so that the winding roller 2 rotates, so that the winding roller 2 can wind the product. At this time, since the diameter of the product wound on the winding roller 2 (hereinafter referred to as the roll product) will gradually increase, it is necessary to operate the tension controller to adjust the tension in the winding process. At this time, it is necessary to know the diameter of the roll product. From the perspective of tension, when the roll diameter increases, if the tension control adjustment is not properly performed, the tension will change. When the roll diameter is small at the beginning of winding, the tension of the finished product is relatively large under the same winding torque. As the roll diameter increases, if the same torque is maintained, the tension of the material will decrease due to the lengthening of the force arm. At this time, it is necessary to control the machine to ensure that the torque of the winding roller 2 and the tension of the wound finished product remain constant. If the measured roll diameter deviates from the actual situation, it will cause the constant tension controlled by the machine to change. Through the two primary distance meters 12, whose output ends are both facing the braided product wound on the winding roller 2, and the two edges of the winding roller 2 are measured, the braided product wound on the winding roller 2 can be measured in real time. The diameter of the fabric is measured. When the roll diameter of the roll changes during the winding process, it means that the distance between the roll and the primary distance meter 12 changes. The data can be sent to the controller 8 in real time, and the two primary distance meters 12 are distributed at both ends of the winding roller 2 and are synchronized. The controller 8 can analyze and judge through a number of data, compare multiple places, and accurately analyze the roll diameter of the roll based on the data at multiple places, so as to avoid the change of the constant tension controlled by the machine due to the inaccurate calculated roll diameter data and the deviation from the actual during the winding process, and avoid the uneven tension of the finished product during winding, thereby improving the winding effect of the machine and further reducing the limitations of the machine when in use; it is worth mentioning that when the winding disc 3 on the winding roller 2 rotates on a number of rotating blocks 9 through the fixed swivel 7, the rotation of the winding roller 2 is limited to avoid shaking or dislocation during rotation, which causes problems in the winding operation, improves the winding effect of the machine, and further improves the stability of the winding roller 2 when in use; thereby reducing the limitations of the machine when in use.

[0037] In some embodiments, the multi-dimensional evaluation component includes a linkage square column 13 symmetrically and slidably arranged on the linkage horizontal plate 6, and the two linkage square columns 13 are connected to a linkage U-shaped frame 14 at the end points close to the winding roller 2. The opening direction of the linkage U-shaped frame 14 faces the winding roller 2 and is also installed with a test semi-ring 15. A lubrication pad 16 is also installed on the inner side wall of the test semi-ring 15. The inner side wall of the lubrication pad 16 is located on the moving path of the woven product wound on the winding roller 2; a plurality of secondary rangefinders 17 are fixedly installed on the inner side wall of the lubrication pad 16, and a sensor is also provided in the secondary rangefinder 17;

[0038] A number of secondary rangefinders 17 are distributed laterally and evenly arranged; linkage square plates 18 are installed at the end points of the two linkage square columns 13 away from the inspection semi-ring 15, and the two linkage square plates 18 are provided with a trigger triangular inclined block 19 on the side away from the linkage U-shaped frame 14, and a driving circular wheel 20 is provided on the moving path of the two inclined surfaces on the trigger triangular inclined block 19, and a limited stop control distance unit is provided on the driving circular wheel 20; a linkage spring 21 is sleeved on the linkage square column 13, one end of the linkage spring 21 is fixedly connected to the linkage horizontal plate 6, and the other end is connected to a No. 1 pressure sensor 22, and the No. 1 pressure sensor 22 is arranged on the side of the linkage U-shaped frame 14 away from the winding roller 2.

[0039] When the roll diameter of the finished product wound on the winding roller 2 becomes larger and larger, it will contact the inspection semi-ring 15 arranged on the side and exert force on it. Under the above-mentioned force, the linkage U-shaped frame 14 on the inspection semi-ring 15 will move to the upper limit position of the linkage cross plate 6 through the two linkage square columns 13, and the linkage spring 21 will be in a buffering state at the same time. The buffering force can reduce the impact force caused by the shaking of the winding roller 2 during winding, thereby improving the stability of the winding roller 2 during winding. The impact force generated by the movement of the product caused by the winding of the winding roller 2 during rotation acts on the machine, causing damage to the machine, thereby reducing the limitations of the machine during use. At the same time, it can be known by observing the moving distance of the linkage square column 13 The size of the roll diameter of the roll product. When the diameter of the roll product increases during winding, the linkage square column 13 moves once. Therefore, the moving distance of the linkage square column 13 can be accurately known through the controller 8, so that the roll diameter size of the roll product at this time can be calculated. At the same time, since one end of the linkage spring 21 is arranged on the No. 1 pressure sensor 22, when the linkage spring 21 is squeezed and is in a buffer state, the moving distance of the linkage square column 13 can be further known through the pressure value. It is transmitted to the controller 8 together with the above value, and the roll diameter of the roll product can be further determined, thereby improving the accuracy of the measurement result, avoiding the deviation between the calculated roll diameter data and the actual situation, resulting in a change in the constant tension controlled by the machine, and real-time control of the output torque of the winding roller 2;

[0040] The multiple data collected at the same time can be used by the controller 8 to further accurately calculate the roll diameter data of the roll product; at the same time, by providing a lubricating pad 16 on the inner wall of the inspection semi-ring 15, the friction between the rotating roll product and the inspection semi-ring 15 can be reduced, thereby avoiding damage to the roll product. At the same time, a number of secondary rangefinders 17 are fixedly installed on the inner wall of the lubricating pad 16, which can monitor the distance between the inspection semi-ring 15 and the roll product in real time, avoiding large errors that lead to large errors in the calculated roll diameter results, thereby further improving the use effect of the machine and the accuracy of the measurement results.

[0041] In some embodiments, the distance limiting unit includes a U-shaped base 23 arranged on the driving circular wheel 20, and a limited movement square column 24 is also installed on the side of the U-shaped base 23 away from the trigger triangular inclined block 19, and a limited movement base 25 is slidably arranged on the limited movement square column 24, and the limited movement base 25 is fixedly arranged on the L-shaped bracket 5; a limited movement spring 26 is sleeved on the limited movement square column 24, one end of the limited movement spring 26 is fixedly connected to the limited movement base 25, and the other end is connected to the limited movement square plate 27, and the limited movement square plate 27 is fixedly arranged on the end of the limited movement square column 24 away from the U-shaped base 23; a bent square rod 28 is installed on the limited square plate 27, and a plurality of bent square rods 28 are provided on the limited square plate 27. The end points of the bent square rod 28 are all facing the winding roller 2 and are installed with a limit cross block 29. The limit slide column 30 is symmetrically and slidably arranged on the limit cross block 29. One end of the limit slide column 30 is connected to the limit circular plate 31, and the other end is connected to the limit arc block 32. The woven product wound on the winding roller 2 is located on the moving path of the limit arc block 32; a limit spring 33 is sleeved on the limit slide column 30, one end of the limit spring 33 is fixedly connected to the limit cross block 29, and the other end is fixedly connected to the limit arc block 32; a buffer rubber pad 34 is also installed on the inner side wall of the limit arc block 32; a pressure alarm module is also arranged on the limit arc block 32.

[0042] When the linkage square column 13 moves, it will drive the trigger triangular inclined block 19 to move. Since the two driving round wheels 20 on one side of the winding roller 2 are in contact with the two inclined surfaces of the trigger triangular inclined block 19, the movement of the trigger triangular inclined block 19 is no longer applied to the driving round wheel 20. When there is no force, the limit spring 26 originally in the buffer state is reset. The reset of the limit spring 26 drives the driving round wheel 20 to reset and move. With the transverse center axis of the winding roller 2 as the axis of symmetry, the two driving round wheels 20 at the upper and lower positions move toward each other, so that they pass through the limit square column 24 on the U-shaped base 23 and move within the upper limit position on the limit base 25. Under the action of the bent square rod 28, the limit cross block 29 is driven to move. Under the action of the limit sliding column 30 and the limit spring 33, the limit arc block 32 is driven to move, so that the limit arc blocks 32 at the upper and lower positions of the winding roller 2 are both moved toward the direction of the rolled product.

[0043] The limit arc block 32 is in a buffer state when the limit arc block 32 contacts the roll, thereby increasing the contact strength between the limit arc block 32 and the roll, and further improving the above-mentioned effect. The buffering force brought by the buffer rubber pad 34 avoids the phenomenon of excessive pressure on the roll and causing damage to the machine due to the excessive diameter of the roll, thereby improving the service life of the machine and further improving the use effect of the machine. After the limit arc block 32 contacts the roll, the limit cross block 29 continues to move, causing it to move within the limit range of the limit slide 30, so that the limit spring 33 and the buffer rubber pad 34 are in a buffer state, thereby increasing the contact strength between the limit arc block 32 and the roll, and further improving the above-mentioned effect. The buffering force brought by the buffer rubber pad 34 avoids the phenomenon of excessive pressure on the roll and causing damage, thereby reducing the limitations of the machine during use and improving the production effect of the machine.

[0044] In some other embodiments, the pressure alarm module also includes a pressure box 35, which is arranged on the side of the limiting horizontal block 29 close to the limiting arc block 32; a pressure block 36 is also provided on the moving path of the pressure box 35, and the pressure block 36 is fixedly provided on the limiting arc block 32; a pressure square plate 37 is slidably arranged in the pressure box 35, and a guide column 38 is provided on the inner side wall of the pressure square plate 37, and the guide column 38 is slidably connected to the pressure square plate 37; a No. 2 pressure sensor 39 is installed on the inner bottom surface of the pressure box 35; a pressure spring 40 is provided in the pressure box 35, one end of the pressure spring 40 is connected to the No. 2 pressure sensor 39, and the other end is connected to the pressure square plate 37, and contacts 41 are installed on the facing surfaces of the pressure square plate 37 and the pressure block 36.

[0045] When the limiting arc block 32 contacts the coil, the limiting cross block 29 is continuously applied with pressure to move the limiting slide 30 to the upper limit, so that the pressure box 35 on the limiting cross block 29 moves toward the limiting arc block 32, and the pressure block 36 on the limiting arc block 32 enters the pressure box 35, so that the contact pieces 41 installed on the facing surfaces of the pressure square plate 37 and the pressure block 36 contact, thereby sending a signal to the controller 8, indicating that the limit of the coil has reached the maximum, so as to notify the operator to come here to process the coil and complete the coiling, so as to avoid the excessive quality of the coil caused by continued coiling and affecting the normal use of the machine, thereby improving the service life of the machine.

[0046] At the same time, if the roll shakes after winding, the impact force brought about will act on the pressure block 36 and the pressure box 35, which will cause the pressure block 36 to continue to move in the pressure box 35, so that the pressure plate 37 moves within the pressure box 35, so that the pressure spring 40 is in a buffering state, and the impact force is collected by the No. 2 pressure sensor 39. When the impact force exceeds the preset value, an alarm is issued to remind the operator to avoid production accidents, thereby improving the safety of the machine during use, avoiding dislocation caused by excessive shaking of the roll, and further improving the use effect of the machine.
