Description

Technical Field

[0002] At present, some textiles are stored and transported in roll form, so some textile workshops are equipped with some rolling mechanisms to carry out fabric winding operations. In textile production, the rolling mechanism is one of the indispensable production equipment. Its main function is to divide the textiles into rolls. Each roll of textile is generally formed by a drum driving the rolling mechanism to roll the textile on it.

[0003] At present, there is a relatively special product in the field of high-strength industrial silk textiles, which is a double-layer space cloth used to make inflatable products. The conventional winding mechanism used to roll up the mesh cloth uses a simple closed-loop control to achieve the winding of double-layer heavy fabrics, and the maximum single roll weight is greater than 1.5 tons; when winding different meters, the large roll system can provide a specific tension for winding, and the tension at this time is constant. The tension of the mesh cloth from zero to the maximum number of meters can be pre-set with a tension gradient (tight inside and loose outside), and the large roll control system can control the real-time cloth winding tension to be consistent with the set gradient value; constant tension winding will have a fatal problem. As the mesh cloth is rolled up, the tension meter relationship achieved cannot achieve a completely fitting effect, resulting in unstable tension and left and right movement during the subsequent further coating processing of the space cloth.

[0004] Therefore, it is necessary to provide a control device for the winding torque that can be controlled according to the spatial cloth winding diameter to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0031] First embodiment

[0032] Please refer to Figure 1-6 ,in, Figure 1 A schematic structural diagram of a first embodiment of a control device for controlling the winding torque according to the spatial cloth winding diameter provided by the utility model; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 A schematic side view of the right side base of the roll stand shown; Figure 4 for Figure 1 The structural schematic diagram of the cloth passing roller bracket shown; Figure 5 The mesh cloth passing path of the control device for controlling the winding torque according to the spatial cloth winding diameter provided by the utility model; Figure 6 The control flow chart of the control device of the winding torque controllable according to the space cloth rolling diameter provided by the utility model. The control device of the winding torque controllable according to the space cloth rolling diameter comprises: a base 1 on the left side of the rolling frame and a base 2 on the right side of the rolling frame;

[0033] A chassis is left on both the left base 1 and the right base 2 of the roll frame, a clamp 3 is fixedly connected to the top of the right base 2 of the roll frame, an inflatable shaft 4 is installed inside the clamp 3, the other end of the inflatable shaft 4 is a movable end, a first bearing 5 is sleeved and placed in a groove at the top of the left base 1 of the roll frame, one end of the inflatable shaft 4 is fixedly connected to a first sprocket 6, a servo motor 7 and a reduction box 8 are installed on the right base 2 of the roll frame, the servo motor 7 and the reduction box 8 are connected through a coupling, a second sprocket 9 is installed on the reduction box 8, a chain 10 is transmission-connected between the first sprocket 6 and the second sprocket 9, and a first Hall proximity switch 24 is arranged on the top of the right base 2 of the roll frame;

[0034] A mounting base 11 is installed on the left side of the right base 2 of the roll stand, a large roller 13 is installed between the mounting base 11 and the left base 1 of the roll stand through a second bearing 12, a vertically fixed magnetic strip 14 is installed on one end of the large roller 13 close to the mounting base 11, a second Hall proximity switch 15 is installed on the mounting base 11, a connecting plate 16 is fixedly connected to the left side of the mounting base 11, two spring rollers 17 are installed between the connecting plate 16 and the left base 1 of the roll stand, an angle potentiometer 18 is installed on the right base 2 of the roll stand, one end of the angle potentiometer 18 is connected to one of the spring rollers 17 by a gear 19, and the other end is fixed to the bracket of the chassis of the right base 2 of the roll stand by a spring 20;

[0035] The package support is supported by the package base on both sides, and a chassis is reserved in the base for installing other components; the spring roller 17 is composed of two rollers, one large and one small, which are fixed as a whole and are connected to the gear 19 to mesh with the angle potentiometer 18 to feed back the current angle (actual tension) information to the control system; the actual number of meters of the large package is measured by the surface of the large roller 13 (with a known diameter) on the package contacting and rolling with the mesh surface. The number of meters of the mesh is the number of rotations of the large roller 13 multiplied by the roller circumference. A second Hall proximity switch 15 is installed at the end of the large roller 13. At the same time, a group of first Hall proximity switches 24 are installed on the air shaft 4 clamp 3 and the first sprocket 6 to calculate the roll diameter of the mesh, and the data of the two are transmitted back to the main control system for data processing. The other end of the angle potentiometer 18 is connected to the spring 20, and the winding zero point, that is, the starting angle of the spring roller 17, can be set; the large roller 13 plays the role of delivering the mesh cloth, so that the bending angle of the mesh cloth will not be too large when it is rolled up to the air shaft 4; the servo motor 7 and the reduction box 8 together constitute the power system of the package, and the first sprocket 6 and the second sprocket 9 are connected by a chain 10, so that the power system can drive the air shaft 4 to roll up the mesh cloth; the air shaft 4 is composed of an inner liner and an axis body. Before the mesh cloth is rolled up, an iron pipe must be put on the outer periphery of the air shaft 4, and then air is added to the inner liner. The air shaft 4 is filled with air to lift the outer iron pipe for rolling; when the mesh cloth is rolled up for a certain number of meters, we need to remove it. At this time, we only need to release the gas from the air shaft 4, and then unscrew the clamp 3 on the right side of the base of the roll frame to use the crane to remove it (the air shaft is on the right side of the package base as the active end)

[0036] A cloth passing roller bracket 21 is fixedly connected to the left base 1 of the left roll rack, a cloth passing roller base 22 is installed on the cloth passing roller bracket 21, and a plurality of cloth passing rollers 23 are arranged inside the cloth passing roller bracket 21.

[0037] After the mesh is woven from the loom, it first enters the cloth roller 23 area, adopts the method of "pressing one and lifting two", passes through the cloth roller 23 area, enters the spring roller 17, winds around the thicker roller above the spring roller 17, and then winds from under the large roller 13 to the air shaft 4. Thus, our mesh winding path is formed.

[0038] The spring 20 and the angle positioner 18 are connected to the external spring roller 17 to form an angle collection system, and the large roller 13, the magnetic strip 14, and the second Hall proximity switch 15 together form a metering system for the package.

[0039] There are six cloth-passing rollers 23, which are placed horizontally. The length of the cloth-passing rollers 23 is the same as the length of the inflatable shaft 4. The distance between two cloth-passing rollers 23 is fixed. From the left, the distance between the third and fourth rollers is twice the distance between the first and second rollers, and the distance between the fourth and fifth rollers is also twice the distance.

[0040] The two sides are fixed with two iron plates, and the cloth-passing roller 23 is required to be a distance from the ground to avoid the mesh touching the ground when passing through, causing dirt. The overall height of the cloth-passing roller 23 should not be too high, and it is roughly the same as the thicker roller height of the spring roller 17.

[0041] The servo motor 7 adopts a torque control mode, and the control pulse is directly issued by the control system of the loom. The servo motor 7 is installed on the base 1 on the left side of the winding frame, and is connected to the reduction box 8 to drive the air shaft 4 to rotate, serving as the power system of the winding package.

[0042] The surface of the large roller 13 is relatively rough, so that during the process of mesh cloth winding, the large roller 13 will rotate along with the traction of the mesh cloth.

[0043] A magnetic strip is also installed at the fixed position of the clamp 3 of the air shaft 4, and a first Hall proximity switch 24 is installed on the first sprocket 6. When the mesh cloth is rolled up, the magnetic strip is fixed, and the first sprocket 6 rotates. As the roll diameter increases, the time for one rotation will become longer, and the increase in the roll diameter of the mesh cloth per turn is a constant value (arithmetic progression);

[0044] The surface of the large roller 13 is relatively rough, and both ends are connected to the second bearing 12, which is relatively flexible as a whole, so that during the process of mesh cloth winding, the large roller 13 will rotate with the mesh cloth traction; the Hall proximity switch 15 is installed on the mounting base 11, and when the magnetic strip 14 approaches, a signal is collected;

[0045] Therefore, we can use these two Hall proximity switches to monitor and calculate the mesh roll diameter in real time.

[0046] The working principle of the meter calculation system of the package is that when the large roller 13 rotates one circle following the mesh cloth, the second Hall proximity switch 15 will sense the magnetic strip 14 once, that is, the number of meters of winding is equal to the circumference of the large roller 13 multiplied by the number of sensing times of the second Hall proximity switch 15.

[0047] The torque output closed-loop system can autonomously adjust the torque output of the servo motor 7 and output the corresponding torque according to the real-time winding diameter. The closed-loop control process is as follows: Figure 6As shown, the main control system outputs a torque pulse signal to drive the servo motor 7 power system, and the power system drives the air shaft 4 to rotate, guiding the mesh cloth to move toward the package. The package passes through the spring roller 17 according to the mesh cloth passing path we use. At this time, the spring roller 17 will be pulled to cause the angle potentiometer 18 gear 19 to rotate. The angle potentiometer 18 reads the current angle value, inputs the analog-to-digital conversion module for conversion, and then inputs the main control system after conversion. At the same time, the large roller 13 will also rotate with the pulling of the mesh cloth, and the second Hall proximity switch 15 is sensed and input into the counting module. The main control system then multiplies the preset circumference of the large roller 13 by the number of inductions to obtain the current number of meters displayed on the display screen; the first Hall proximity switch 24 at the clamp 3-first sprocket 6 of the air shaft 4 starts counting at the same time, and transmits the data of the two Hall proximity switches back to the main control system at the same time. The system will process the current corresponding roll diameter value and output the corresponding torque according to the roll diameter value to control the mesh cloth to be rolled up.

[0048] The working principle of the control device for controlling the take-up torque with the spatial cloth roll diameter provided by the utility model is as follows:

[0049] When the mesh is rolled up, the spring roller 17 rotates a certain angle due to the traction of the mesh, and the gear 19 meshing with the angle potentiometer 18 will rotate at this time, and the corresponding angle change value can be collected; the servo motor 7 and the reduction box 8 are installed above the base 2 on the right side of the roll frame, and the two are connected to the chain 10 through the first sprocket 6 and the second sprocket 9 to form a power system to drive the air shaft 4 to rotate; the air shaft 4 is composed of an inner liner and a shaft body. When rolling up, the shaft body is covered with an iron pipe, and the inner liner is inflated to serve as a rolling base; one end of the air shaft 4 is a movable end, which is covered with a first bearing 5 and placed in the groove of the base 1 on the left side of the roll frame, and the other end is fixed by a clamp 3 and rotates with the power system. When the mesh is rolled up for a certain number of meters, we need to remove it. At this time, we only need to release the gas from the air shaft 4, and then unscrew the clamp 3 of the base 2 on the right side of the roll frame to use a crane to remove it. When the large roller 13 rotates one circle, it will sense the second Hall proximity switch 15 fixed on the mounting base 11, and the mesh cloth will be rolled up to drive the first sprocket 6 to rotate, and the first Hall proximity switch 24 fixed on the hoop 3 and the first sprocket 6 will start working.

[0050] Compared with the related art, the control device for controlling the winding torque according to the spatial cloth winding diameter provided by the utility model has the following beneficial effects:

[0051] The utility model improves the problem of left and right deviation of the subsequent coating caused by constant tension winding. The cloth passing roller device can effectively adjust the spatial mesh cloth misalignment problem. The torque closed-loop control can achieve autonomous adjustment inside the system. The winding torque changes in real time with the winding diameter. The mechanical part of the entire winding system has a relatively long width and can be suitable for the winding of most mesh cloths. It is widely applicable.

The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0054] Specifically, the control device for the controllable winding torque with the spatial cloth roll diameter provided in the second embodiment of the present application is different in that a mounting block 25 is fixedly connected to the top of the base 2 on the right side of the roll rack, and grooves 26 are provided on the left and right sides of the mounting block 25. A rotating shaft 27 is rotatably connected inside the groove 26, and a torsion spring 28 is provided on the outer surface of the rotating shaft 27. A fixed block 29 is fixedly connected to the rotating shaft 27, and a shift block 30 is fixedly connected to one side of the fixed block 29.

[0055] A through slot 31 is formed inside the mounting block 25 , and the through slot 31 is connected to the two grooves 26 . A sliding block 32 is slidably connected inside the through slot 31 . A positioning slot 33 is formed on the outer surface of the rotating shaft 27 , and a positioning block 34 is fixedly connected to the top of the sliding block 32 .

[0056] By using the positioning block 34 and the positioning groove 33 in coordination, the rotation shaft 27 can be limited and fixed.

[0058] The sliding block 32 is made of metal. Two sides of the sliding block 32 respectively penetrate the two grooves 26 and extend to the outside of the grooves 26 .

[0059] The sliding block 32 is made of a metal that can be attracted to the first magnetic block 35 and the second magnetic block 36 , such as ferromagnetic materials such as iron, cobalt, and nickel. The sliding block 32 passes through the groove 26 to facilitate operation by the operator.

[0060] Compared with the related art, the control device for controlling the winding torque according to the spatial cloth winding diameter provided by the utility model has the following beneficial effects:

[0061] After the inflatable shaft 4 is installed on the mounting block 25, the inflatable shaft 4 can be installed and fixed by the relative swing of the two fixing blocks 29. When disassembling, it is only necessary to move the shifting blocks 30 on both sides with one hand, so that the two shifting blocks 30 swing away from each other, thereby making the two fixing blocks 29 swing away from each other, so that the top port of the mounting block 25 is opened, so that the inflatable shaft 4 can be disassembled and replaced, and the one-handed operation is more convenient, which greatly reduces the difficulty of assembly, and the positioning block 34 is inserted into the inside of the positioning groove 33, which can be further stabilized, and the rotating shaft 27 is locked, thereby improving the fixing effect.
