Description

Technical Field

[0001] The invention relates to the technical field of nonwoven fabrics, and more particularly to an anti-slip device for winding and unwinding equipment. Background Art

[0002] In the material processing industry, winding and unwinding equipment is widely used in the conveying, winding and storage processes of coiled materials. The original cloth roll is formed into a new cloth roll through the winding and unwinding equipment. For example, the prior art with announcement number CN221295610U discloses a dual-mode non-woven fabric slitting machine system, including a frame and an unwinding device and a winding device installed on the frame, and also includes a tension roller installed on the frame. However, the original coil is rotatably set on a roller. In order to prevent it from pulling out too much coiled material during rotation, it is necessary to fit a belt on the original cloth roll for anti-skid. However, the existing anti-skid device cannot be adjusted and cannot adapt to the radius change after the original coiled material is released, resulting in a poor anti-skid effect.

[0003] Therefore, how to better make the original coiled material anti-slip is exactly the technical problem to be solved by this application. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention proposes an anti-skid device for a reeling and unreeling device, which controls the tension of the anti-skid component by calculating the anti-skid force of the original cloth roll.

[0005] The present invention provides an anti-skid device for a winding and unwinding device, and the technical solution is as follows:

[0006] An anti-skid device for a reeling and unreeling device, comprising a placing roller, an upper guide roller, a lower guide roller, an anti-skid member and a belt, wherein the placing roller is used for rotating the original cloth roll;

[0007] The upper guide roller, the placing roller and the lower guide roller extend in the same direction, and the placing roller is located between the upper guide roller and the lower guide roller;

[0008] The belt is connected end to end and wrapped around the upper guide roller, the lower guide roller and the anti-skid member, so as to form an anti-skid surface between the upper guide roller and the lower guide roller. The anti-skid surface is used to resist the original cloth roll on the placement roller, so as to prevent the original cloth roll from slipping.

[0009] The anti-slip part changes the tension of the belt on the original cloth roll by changing the path of the belt.

[0010] In summary, the above technical scheme has the following beneficial effects: in the present application, the upper guide roller, the placement roller and the lower guide roller are located on the same plane, and the belt will fit the original cloth roll after being tensioned, thereby preventing the original cloth roll from slipping, and when the original cloth roll rotates to pull out the cloth roll, the belt cooperates with the original cloth roll to maintain the same linear speed of rotation. When the original cloth roll is pulled out, the radius of the original cloth roll will change. The present application changes the path of the belt through the anti-slip part, thereby adjusting the tension of the belt, so that the belt can adapt to the changed radius of the original cloth roll, and can have an anti-slip effect on original cloth rolls with different radii.

DETAILED DESCRIPTION

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1As shown, an anti-skid device of a winding and unwinding device 80 includes a placing roller 10, an upper guide roller 20, a lower guide roller 30, an anti-skid member 40 and a belt 50. The placing roller 10 is used for rotating the original cloth roll 1; the upper guide roller 20, the placing roller 10 and the lower guide roller 30 extend in the same direction, and the placing roller 10 is located between the upper guide roller 20 and the lower guide roller 30; the belt 50 is connected end to end and surrounds the upper guide roller 20, the lower guide roller 30 and the anti-skid member 40, so as to form an anti-skid surface 51 between the upper guide roller 20 and the lower guide roller 30, and the anti-skid surface 51 is used to resist the original cloth roll 1 on the placing roller 10, so as to prevent the original cloth roll 1 from slipping; the anti-skid member 40 changes the tension of the belt 50 on the original cloth roll 1 by changing the path of the belt 50.

[0018] In the present application, the upper guide roller 20, the placement roller 10 and the lower guide roller 30 are located on the same plane. After the belt 50 is tensioned, it will fit the original cloth roll 1, thereby preventing the original cloth roll 1 from slipping. When the original cloth roll 1 rotates to pull out the cloth roll, the belt 50 cooperates with the original cloth roll 1 to maintain the same linear speed of rotation. When the original cloth roll 1 is pulled out, the radius of the original cloth roll 1 will change. The present application changes the path of the belt 50 through the anti-slip part 40, thereby adjusting the tension of the belt 50, so that the belt 50 can adapt to the changed radius of the original cloth roll 1, and can have an anti-slip effect on the original cloth rolls 1 with different radii.

[0019] like Figure 2 As shown, the anti-slip member 40 includes a fixed seat 41 and a rotating arm 42, and anti-slip rollers 43 are provided at both ends of the rotating arm 42. The middle of the rotating arm 42 is rotatably connected to the fixed seat 41, and a control member 44 for controlling the rotation of the rotating arm 42 is provided on the fixed seat 41. The belt 50 is located between the anti-slip rollers 43 at both ends of the rotating arm 42.

[0020] Specifically, two rotating arms 42 are provided, and the two ends of the two rotating arms 42 are rotatably connected to an anti-skid roller 43, thereby forming a square-shaped structure. The belt 50 passes through the square-shaped structure, so that the two anti-skid rollers 43 are located on the front and back sides of the belt 50. The control member 44 changes the path of the belt 50 by controlling the rotating arm 42 to rotate. After the path of the belt 50 becomes longer, the tension of the anti-skid surface 51 on the original cloth roll 1 will increase, so that after the original cloth roll 1 is pulled out and becomes smaller, a certain tension can be maintained, thereby achieving an anti-skid effect. Of course, any structure that can change the path of the belt 50 can be used as the anti-skid member 40 of the present application, for example, a commonly used roller with a telescopic rod can also adjust the tension of the belt 50, or one end of the above-mentioned rotating arm 42 is connected to the fixed seat 41, and the other end is rotated to control the change of the path of the belt 50, which can also change the tension of the belt 50. Therefore, the structure of the anti-skid member 40 is not unique, and other structures that can change the path of the belt 50 should be within the scope of protection of the present application.

[0021] like Figure 3 As shown, it also includes a controller 60 and a tension detection module 70. The tension detection module 70 and the anti-slip member 40 are electrically connected to the controller 60 respectively; the tension detection module 70 is connected to the belt 50 to detect the tension applied to the belt 50; the controller 60 controls the tension of the anti-slip member 40 according to the tension change detected by the tension detection module 70.

[0022] The tension detection module 70 is a component for measuring the tension value of the coil, which is widely used in the field of non-woven fabrics. The tension detection module 70 includes a bearing seat and guide rollers located on both sides of the bearing seat. The tension detection sensor is arranged on the bearing seat, which can detect the force applied by the belt 50 on the bearing seat. The guide rollers on both sides are fixed, so the force detected by the tension detection sensor can be decomposed to obtain the tension of the belt 50. The present application accurately determines the tension change of the belt 50 through the tension detection module 70, so that the tension of the belt 50 can be better controlled through the anti-slip member 40. Specifically, the controller 60 is electrically connected to the control member 44, and the control member 44 controls the rotation of the rotating arm 42 to adjust the tension of the belt 50.

[0023] The common section of the upper guide roller 20 and the lower guide roller 30 located on one side of the belt 50 passes through the dot of the placement roller 10. After the original cloth roll 1 on the placement roller 10 hits the belt 50, the anti-slip surface 51 of the belt 50 forms an anti-slip angle. The anti-slip force of the belt 50 on the original cloth roll 1 is calculated according to the anti-slip angle and the tension of the belt 50. The controller 60 controls the tension of the belt 50 through the tensioner so that the anti-slip force of the belt 50 on the original cloth roll 1 remains unchanged.

[0024] The force acting on the original cloth roll 1 is the anti-skid force of the belt 50 on the original cloth roll 1. In order to make the original cloth roll 1 more stable when being pulled out, the anti-skid force should be controlled to remain unchanged. The anti-skid force is related to the tension of the belt 50 and the anti-skid angle formed by the anti-skid surface 51. The present application does not directly use the tension detected by the tension detection module 70 to control the tension of the belt 50, but uses it as a parameter for calculating the anti-skid force. The radius of the original cloth roll 1 will become smaller during the process of being pulled out, and the anti-skid angle and the path of the belt 50 will change, so that the anti-skid force of the belt 50 on the original cloth roll 1 will also change accordingly. Because the anti-skid angle has changed, simply keeping the tension of the belt 50 unchanged cannot keep the anti-skid force unchanged. It is necessary to recalculate the anti-skid force acting on the original cloth roll 1 according to the anti-skid angle, and keep the anti-skid force unchanged by increasing the tension of the belt 50.

[0025] like Figure 4 As shown, the anti-slip angle α is calculated by the distance L from the center of the placing roller 10 to one end of the anti-slip surface 51 and the radius R of the original cloth roll 1 .

[0026] The distance L from the center of the placement roller 10 to one end of the anti-skid surface 51 is a fixed value, which can be measured after preliminary settings. The common tangent plane of the upper guide roller 20 and the lower guide roller 30 on one side of the belt 50 passes through the point of the placement roller 10, so the radius of the original cloth roll 1 is perpendicular to the common tangent plane of the upper guide roller 20 and the lower guide roller 30 on one side of the belt 50. The two component forces of the anti-skid surface 51 are equal. The magnitude of the anti-skid force acting on the original cloth roll 1 can be calculated by a mathematical formula. This is only controlled by mathematical formula calculation, without adding other accessories, and can be achieved by only inputting the corresponding control program into the controller 60 of the original winding and unwinding device 80, saving a lot of cost.

[0027] The controller 60 is connected to a reeling and unreeling device 80, which is used to extract the original cloth roll 1 and form a new cloth roll. The controller 60 obtains the extracted length of the original cloth roll 1 through the reeling and unreeling device 80. , the remaining length of the original cloth roll 1 The following relationship is satisfied:

[0028]

[0029] in, is the remaining length of the original cloth roll 1, is the radius of the placing roller 10, is the thickness of one layer of the original cloth roll, is the number of layers of the original cloth roll 1, the initial length of the original cloth roll 1 Minus the extraction length The remaining length of the original cloth roll 1 , the radius R of the original cloth roll 1 is calculated by the following formula:

[0030]

[0031] in, is the radius of the placing roller 10, is the thickness of one layer of the original cloth roll, is the number of layers of original fabric roll 1;

[0032] The anti-slip angle α satisfies the following relationship:

[0033]

[0034] in, It is the distance from the center of the placing roller 10 to one end of the anti-slip surface 51.

[0035] The winding and unwinding device 80 is a prior art. The structure of the "automatic tensioning winding and unwinding device" declared by the applicant can be referred to. The motor drives the roller to control the coil withdrawal. The controller 60 can calculate the length of the coil withdrawal by combining the motor speed with the roller linear speed. . The initial length of the original cloth roll 1 , radius of the roller , the thickness of one layer of original cloth roll Given the condition, the thickness of the original cloth roll 1 layer is It can be approximately equal to the thickness of one layer of the original cloth roll 1, because there may be gaps between each layer of the original cloth roll 1 if it is not pressed tightly, and the thickness of one layer of the original cloth roll 1 is obtained by adding the thickness of the gap. The relationship can be used to calculate how many layers of the original cloth roll 1 are left, and thus calculate the radius of the original cloth roll 1 Because the midpoint of the placing roller 10 is on the common tangent line of the upper guide roller 20 and the lower guide roller 30 on one side of the belt 50, the anti-slip angle α can be calculated by trigonometric function. The anti-slip angle α changes in real time as the original cloth roll 1 is drawn out, so the controller 60 needs to calculate in real time.

[0036] Anti-slip and belt tension 50 The following relationship is satisfied:

[0037]

[0038] in, is the anti-slip angle.

[0039] Tension of belt 50 The tension detection module 70 detects and transmits it to the controller 60 in real time, and calculates the real-time anti-slip force according to the real-time anti-slip angle α. , so that the controller 60 controls the anti-skid force Keep it as a fixed value. In this way, the anti-skid force acting on the original cloth roll 1 remains unchanged, which can make the process of pulling out the coil of the original cloth roll 1 more stable, and will not cause unstable situations such as slipping due to pressure changes.

[0040] The storage seat 90 is also included, and the storage roller 10 is rotatably arranged on the storage seat 90, and the storage seat 90 is used to adjust the position of the storage roller 10. Because the anti-slip force calculation of the present application has certain requirements on the position of the storage roller 10, the storage seat 90 is provided to adjust the position of the storage roller 10.

[0041] The storage seat 90 includes a base 91 and a telescopic portion 92, the telescopic portion 92 and the base 91 are slidably connected, and the storage roller 10 is rotatably arranged at one end of the telescopic portion 92 away from the base 91. The telescopic portion 92 can adjust the height of the storage roller 10, and after adjustment, the telescopic portion 92 and the base 91 are fixed by bolts. The horizontal position of the storage roller 10 is achieved by directly moving the base 91.

[0042] The device also includes a fixing plate, which is fixedly connected to the unwinding and reeling device 80, and a base 91 is detachably fixed to the fixing plate. The unwinding and reeling device 80 is large in size and heavy in weight. After the adjusting seat adjusts the position of the placing roller 10, it will be subjected to the anti-slip force of the belt 50. In order to keep the position of the placing roller 10 stable, a fixing plate is provided, and the base 91 is detachably fixed to the fixing plate, for example, by bolts, so that the placing roller 10 can be prevented from displacement or shaking.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
