[0021] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0022] An embodiment of the present application provides an active cloth-releasing device for laminated non-woven fabrics, which is used to actively unwind non-woven fabrics downstream and is particularly suitable for the production of TPE laminated non-woven fabrics.

[0023] like Figure 1As shown, the active cloth-releasing device includes: a frame 10, and a cloth-releasing mechanism 20, a traction mechanism 30, and a tension detection mechanism 40 mounted on the frame 10. In the product unwinding path, the cloth-releasing mechanism 20, the traction mechanism 30, and the tension detection mechanism 40 are arranged in sequence from upstream to downstream. The cloth-releasing mechanism 20 is mounted on the top of the frame 10 and is used to carry the rolled product and actively release the carried product downstream. The traction mechanism 30 and the tension detection mechanism 40 are mounted on the frame 10 and are located below the cloth-releasing mechanism 20. The traction mechanism 30 is used to pull the product actively released by the cloth-releasing mechanism 20, guiding the product transportation. The tension detection mechanism 40 is used to detect the tension of the unwound product, so that the cloth-releasing mechanism 20 can adjust the tension of the product during unwinding.

[0024] like Figure 2 As shown, the frame 10 includes a base frame 1, a pair of wall panels 2 and a plurality of cross beams 3 connected between the pair of wall panels 2. The pair of wall panels 2 are mounted on the base frame 1 opposite to each other on the left and right sides, and each cross beam 3 extends in the left and right direction.

[0025] like Figure 1 、 2 As shown, in the embodiment of the present application, the cloth unwinding mechanism 20 includes two unwinding stations 50. The two unwinding stations 50 alternately unwind the cloth, achieving uninterrupted cloth unwinding, greatly improving production efficiency. Each unwinding station 50 is equipped with an unwinding device 4 and a correction device 5. The unwinding device 4 is mounted on the top of the frame 10 so that it can move in the left-right direction. The correction device 5 is arranged on one side of the unwinding device 4 to drive the unwinding device 4 to move in the left-right direction.

[0026] Each unwinding station 50 is further provided with a pair of guide rail support seats 6 arranged opposite to each other on the left and right sides. Each guide rail support seat 6 is fixedly mounted on the top of a wall panel 2 , and the unwinding device 4 is slidably mounted on the pair of guide rail support seats 6 .

[0027] The unwinding device 4 includes an inflatable shaft 41 extending in the left-right direction, an unwinding motor 42 connected to the inflatable shaft 41, a first bearing support seat 43 and a second bearing support seat 44 for supporting the inflatable shaft 41, a motor mounting seat 45 for supporting the unwinding motor 42, and a first sliding assembly 46 and a second sliding assembly 47 respectively installed on a pair of guide rail support seats 6.

[0028] The first bearing support seat 43 and the second bearing support seat 44 are respectively supported on the left end and the right end of the inflatable shaft 41, so that the inflatable shaft 41 can rotate around its own axis relative to the frame 10 through the first bearing support seat 43 and the second bearing support seat 44.

[0029] The first bearing support 43 is mounted on the motor mounting seat 45, and the motor mounting seat 45 is slidably mounted on one guide rail support seat 6 in the left-right direction via a first sliding assembly 46. The second bearing support 44 is slidably mounted on the other guide rail support seat 6 in the left-right direction via a second sliding assembly 47.

[0030] A transmission assembly 48 is connected between the unwinding motor 42 and the inflatable shaft 41. The transmission assembly 48 includes a passive gear 481 coaxially mounted on the inflatable shaft 41 and a driving gear 482 coaxially mounted on the transmission shaft of the unwinding motor 42. The driving gear 482 meshes with the passive gear 481. The motor mounting base 45 allows the unwinding motor 42 and the inflatable shaft 41 to move synchronously left and right, preventing the driving gear 482 and the passive gear 481 from disengaging, thereby ensuring transmission between the unwinding motor 42 and the inflatable shaft 41.

[0031] The structures of the first sliding assembly 46 and the second sliding assembly 47 are consistent. Each sliding assembly includes a guide rail extending in the left and right directions and a slider slidingly engaged with the guide rail. The guide rail is installed on the top of the corresponding guide rail support seat 6. The slider of the first sliding assembly 46 is installed on the bottom of the motor mounting seat 45, and the slider of the second sliding assembly 47 is installed on the bottom of the second bearing support seat 44.

[0032] like Figure 2 As shown, the deflection correction device 5 is arranged on the same side as the unwinding motor 42. The deflection correction device 5 includes a deflection correction mounting bracket 51 and a deflection correction cylinder 52. The deflection correction mounting bracket 51 is installed on the left wall panel 2. The deflection correction cylinder 52 is connected between the deflection correction mounting bracket 51 and the motor mounting base 45. When the deflection correction cylinder 52 is in operation, the motor mounting base 45 moves in the left and right directions under the push of the deflection correction cylinder 52, driving the entire unwinding device 4 to move in the left and right directions. When the pneumatic shaft 41 is unwinding the fabric, the deflection correction device 5 can promptly adjust the lateral position of the product and correct the deviation. This can prevent the product from stretching, wrinkling, or scratching due to uneven lateral tension caused by the deviation, further improving the fabric unwinding effect.

[0033] Continue to refer to Figure 1 and Figure 2The traction mechanism 30 includes an active pressure roller 7 parallel to the inflatable shaft 41, a passive pressure roller 8 parallel to the active pressure roller 7, and a pressing cylinder 9 connected to the passive pressure roller 8. The active pressure roller 7 and the passive pressure roller 8 are arranged relative to each other in front and back, and are both rotatable around their own axis through bearing seats between a pair of wall panels 2. The pressing cylinder 9 is connected to the bearing seat of the passive pressure roller 8 and is used to drive the passive pressure roller 8 to move closer to and away from the active pressure roller 7. When the cloth-laying mechanism 20 is laying cloth, the pressing cylinder 9 drives the passive pressure roller 8 to press the product onto the active pressure roller 7. The active pressure roller 7 and the passive pressure roller 8 clamp the product. The linear speed of the active pressure roller 7 is consistent with the linear speed of the unwinding of the inflatable shaft 41, so that the friction between the active pressure roller 7 and the passive pressure roller 8 and the product is reduced, ensuring that the product is flattened during transportation, avoiding the product from being pulled, wrinkled or scratched, and improving the unwinding quality and product quality.

[0034] The tension detection mechanism 40 is mounted on the frame 10 and is also located below the fabric unwinding mechanism 20. The tension detection mechanism 40 includes a tension guide roller 11 parallel to the pneumatic shaft 41 and a tension sensor 12 mounted on the tension guide roller 11. The tension guide roller 11 is mounted between a pair of wall panels 2 so that it can rotate about its own axis. The tension sensor 12 is used to detect the tension of the product passing around the tension guide roller 11. The tension sensor 12 transmits the detection result to the control system of the active fabric unwinding mechanism. The control system controls the operation of the unwinding motor 42 and the correction cylinder 52, so that the unwinding device 4 adjusts the tension of the product during unwinding, achieving constant tension unwinding. In addition, when the tension sensor 12 detects that the product has inconsistent lateral tension, the control system adjusts the lateral position of the pneumatic shaft 41 through the correction device 5, so that the product conveying direction is perpendicular to the tension guide roller 11, achieving correction. The flexible operation of the unwinding motor 42 and the correction cylinder 52 can meet the production needs of different speeds and a variety of products.

[0035] A transition aluminum roller 13 is provided upstream and downstream of the tension guide roller 11 respectively. Each transition aluminum roller 13 is parallel to the tension guide roller 11 and is mounted on the frame 10 so as to be rotatable around its own axis. The product passes through a transition aluminum roller 13, the tension guide roller 11 and another transition aluminum roller 13 in an "S" shape from upstream to downstream to ensure smoothness during transportation.

[0036] The active cloth-releasing equipment of the present application realizes uninterrupted unwinding by alternating active cloth-releasing at two workstations, and realizes deviation correction and tension adjustment through a tension detection mechanism and a deviation correction device, thereby avoiding quality problems such as products being pulled, wrinkled, and scratched. The operation is convenient, the production efficiency is high, and the product quality is guaranteed.

[0037] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes.
