Description

Technical Field

[0001] A coiling machine belongs to the field of textile equipment. Background Art

[0002] A coiling machine is a machine in the prior art for circular packaging of various fabrics, non-woven fabrics and other materials and repeated coiling before various fabrics are cut into strips. Since there is a certain tension in the fabric itself during the coiling process through the coiling machine. Due to the relatively soft characteristics of textile fabrics, if the tension in the coiling machine is abnormal, the fabric is prone to wrinkles, thus affecting the quality of the product.

[0003] Therefore, in the prior art, in the textile field and related fields, when conveying flexible and long materials such as similar fabrics, a tension detection scheme needs to be set up and the tension is adjusted. In the prior art, for tension detection, various sensors are generally used to achieve it: the technical scheme of indirectly reflecting the tension according to the swing angle of the pendulum rod collected by the encoder adopted in the Chinese utility model patent with the application number 201820010811.3, the application date of January 4, 2018, and the patent name of "A Fiber Winding Unwinding Tension Control System"; the technical scheme of indirectly reflecting the tension by collecting the swing angle of the gear by the encoder and further calculating the lifting distance of the tension roller adopted in the Chinese utility model patent with the application number 201710647342.6, the application date of August 1, 2017, and the patent name of "A Tension Control Device for a Rewinding Machine"; the technical scheme of directly detecting the tension according to the output current of the tension ammeter adopted in the Chinese utility model patent with the application number 201821039225.8, the application date of July 2, 2018, and the patent name of "A Detection System for a Copper Clad Laminate Machine"; the technical scheme of directly detecting the tension according to the output current of the tension ammeter adopted in the Chinese utility model patent with the application number 201821039225.8, the application date of July 2, 2018, and the patent name of "A Detection System for a Copper Clad Laminate Machine"; the technical scheme of indirectly reflecting the tension by using the elastic force of the spring adopted in the Chinese utility model patent with the application number 202021635681.6, the application date of August 9, 2020, and the patent name of "A Tension Adjusting Component for a Rewinding Machine"; the technical scheme of indirectly reflecting the tension by using the pressure borne by the adjusting cylinder adopted in the Chinese utility model patent with the application number 201520959137.X, the application date of November 27, 2015, and the patent name of "A Fabric Pneumatic Edge Suction System with a Tension Control System"; and the technical scheme of indirectly reflecting the tension by controlling the winding motor by obtaining the real-time torque through the initial parameters set by the PLC controller and the real-time coil diameter and performing fuzzy operation by introducing the taper adopted in the Chinese utility model patent with the application number 202121475617.0, the application date of July 1, 2021, and the patent name of "A Non-indentation Variable Tension Rewinding Mechanism".

[0004] In the prior art, whether in the textile field or in other adjacent fields, when it comes to tension adjustment, the technical solutions all have a similar design idea for materials: that is, a set value of tension is preset, then the tension value is collected in real time, and then by comparing the real-time value of the tension with the set value, the tension value is further increased or decreased. However, the applicant found that in the actual implementation of the existing tension adjustment scheme in the textile field, there will still be cases of fabric wrinkles. After experiments, it was found that the reason is that: during the process of winding the fabric, the quantity of the fabric on the cloth roller at the starting point and the quantity of the fabric on the cloth roller at the ending point in the winding machine are changing in real time. This conversion of the fabric quantity (length) will affect the tension of the fabric during the transmission process. That is, there is a common misconception in the textile field, that is: during the transmission process of the fabric, the tension should be a fixed value.

[0005] Therefore, although the prior art including the above technical solutions can also largely avoid defects such as fabric wrinkles to a great extent, it still cannot be completely avoided. Therefore, designing a technical solution that gradually adjusts the tension of the fabric itself during the operation of the fabric to avoid fabric wrinkles has become an urgent problem to be solved in this field. Summary of the Utility Model

[0006] The technical problem to be solved by the present utility model is: to overcome the deficiencies of the prior art and provide a winding machine that calculates the moving length of the fabric through a counter, gradually changes the tension applied to the fabric, realizes the segmented adjustment of the tension, and effectively avoids the problem of fabric wrinkles that still occurs when setting a fixed tension threshold in the prior art.

[0018] Figure 1 It is the best embodiment of the present utility model, and the present utility model will be further described below in conjunction with the attached Figure 1 to further illustrate the present utility model.

[0019] As Figure 1 shown, a coiling machine includes a support column 3, and the support column 3 is vertically fixed on the ground. A bracket is provided on one side of the support column 3, and a fabric roller 10 is provided on the bracket, and the fabric 9 is wound around the fabric roller 10. In this coiling machine, the side where the fabric roller 10 is provided is defined as the front side of this coiling machine.

[0020] A rear support arm 2 is horizontally provided at the rear side of the top of the support column 3, and a front support arm 8 is horizontally provided at the front side of the support column 3. The height of the front support arm 8 is lower than the height of the rear support arm 2. Two front support arms 8 and two rear support arms 2 are respectively horizontally arranged along the left-right direction of this coiling machine.

[0021] A rear guiding roller 1 is provided at the end of the rear support arm 2, and the rear guiding roller 1 is installed on the upper surfaces of two rear support arms 2 through brackets at both ends thereof. A front guiding roller 7 is provided at the end of the front support arm 8, and a cloth guiding roller 4 is further provided on the upper surface of the inner end of the front support arm 8. The front guiding roller 7 and the cloth guiding roller 4 are also respectively installed on the upper surfaces of the left and right front support arms 8 through brackets at both ends thereof.

[0022] A tension driving mechanism 5 is provided in the middle of one of the front support arms 8. The tension driving mechanism 5 includes a driving motor and a speed reducer. The motor shaft of the driving motor is connected to the input shaft of the speed reducer, and a tension arm 6 is installed at the output shaft of the speed reducer. There are two tension arms 6, and the other tension arm 6 is rotatably installed on the surface of the other front support arm 8 through a bracket (not shown in the figure).

[0023] Two tension rollers are provided between the two tension arms 6. The two tension rollers are respectively installed at both ends of the two tension arms 6, and the axis of one of the tension rollers is collinear with the axial direction of the output shaft of the speed reducer. When the driving motor rotates, it drives the two tension arms 6 at both ends to swing through the speed reducer, so as to realize the adjustment of the relative position between the two tension rollers, and finally realize the adjustment of the tension.

[0024] Same as the prior art, a control cabinet 11 and a power cabinet 12 are provided on one side of the lower part of the column 3. A controller of this coiling machine is provided in the control cabinet 11, and a power mechanism of this coiling machine is provided in the power cabinet 12. The power mechanism includes a driving motor and a transmission mechanism well known in the art. A driving roller 14 is led out from the power mechanism. The driving roller 14 is located on the upper surface of the base of the column 3, and the power mechanism in the power cabinet 12 drives the driving roller 14 to rotate.

[0025] A counter 13 is provided on the upper surface of the base of the column 3 through a bracket. The rotating part of the counter 13 is in contact with the driving roller 14. When the driving roller 14 rotates, it drives the counter 13 to rotate synchronously. The counter 13 can be realized by a common encoder in the art. The signal output end of the counter 13 is connected into the control cabinet 11 and is connected to the output end of the controller. A touch screen is also provided on the surface of the control cabinet 11, and the touch screen is also connected to the controller.

[0026] The specific working process and working principle are as follows:

[0027] The cloth 9 is led out from the cloth roller 10 and extends upward to the end of the front support arm 8, then bypasses from the upper part of the front cloth guiding roller 7, and then the cloth 9 bypasses the two tension rollers and the cloth guiding roller 4 in sequence and then extends to the top of the rear guiding roller 1, bypasses from the top of the rear guiding roller 1 and then vertically downward, and then extends backward after bypassing from the bottom of the driving roller 14.

[0028] When the driving roller 14 rotates, it drives the fabric 9 to gradually unload from the fabric roller 10, and then sends it to the subsequent structure for coiling operation. During the rotation of the driving roller 14, the counter 13 is driven to rotate at the same time. At this time, the controller measures the length of the fabric 9 according to the data at the output end of the counter 13. Since the lengths of the fabric 9 wound on each fabric roller 10 are basically the same, the total length of the fabric 9 is divided into N segments by the controller. When each segment of the total length of the fabric 9 runs, according to the section of the total length where the moving length of the fabric 9 is located, the controller controls the driving motor to work, and drives the tension arm 6 to swing segment by segment, so that the tension applied by the tension roller on the fabric 9 gradually increases. The total length of the fabric 9 can also be modified according to the touch screen on the surface of the control cabinet 11.

[0029] Therefore, in this coiling machine, by gradually changing the tension applied to the fabric 9 according to the length that the fabric 9 has moved, the segmented adjustment of the tension is realized, effectively avoiding the problem that the fabric 9 still wrinkles when a fixed tension threshold is set in the prior art.

[0030] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
