Description

Technical Field

[0001] The utility model relates to the technical field of stretching equipment, in particular to a stretching equipment for non-woven flat bag materials. Background Art

[0002] Non-woven fabric is one of the raw materials for making flat bags. Before using non-woven fabric to make flat bags, it is necessary to ensure that the fabric itself has strong elasticity. Therefore, during the production of non-woven fabric, the non-woven fabric needs to be stretched to increase its own elasticity; non-woven fabric has no warp and weft, is very easy to cut and sew, is light and easy to shape, so it is deeply loved by handicraft enthusiasts; non-woven fabric is a fabric that does not require spinning and weaving. It simply randomly orients or arranges textile fibers or filaments to form a fiber network structure, and then reinforces it by mechanical, thermal or chemical methods; it is not woven from yarns one by one, but the fibers are directly combined together by physical methods.

[0003] In specific non-woven fabric application fields, in traditional non-woven fabric stretching equipment, the two sides of the non-woven fabric are generally fixed, and then biaxial stretching is performed. During the biaxial rapid stretching process, if the non-woven fabric is not clamped tightly enough, the fabric will loosen and fall off during the stretching process, ultimately affecting the overall quality of the non-woven fabric.

[0032] Non-woven fabric is one of the raw materials for making flat bags. Before using non-woven fabric to make flat bags, it is necessary to ensure that the fabric itself has strong elasticity. Therefore, during the production of non-woven fabric, the non-woven fabric needs to be stretched to increase its own elasticity; non-woven fabric has no warp and weft, is very easy to cut and sew, is light and easy to shape, so it is deeply loved by handicraft enthusiasts; non-woven fabric is a fabric that does not require spinning and weaving. It simply randomly orients or arranges textile fibers or filaments to form a fiber network structure, and then reinforces it by mechanical, thermal or chemical methods; it is not woven from yarns one by one, but the fibers are directly combined together by physical methods.

[0033] In specific non-woven fabric application fields, in traditional non-woven fabric stretching equipment, the two sides of the non-woven fabric are generally fixed, and then biaxial stretching is performed. During the biaxial rapid stretching process, if the non-woven fabric is not clamped tightly enough, the fabric will fall off during the stretching process, ultimately affecting the overall quality of the non-woven fabric.

[0034] Based on this, the technical problem in the related art that non-woven fabrics are prone to falling off during the stretching process can be improved, and the embodiments of the present application provide the following solution.

[0035] Please also read Figures 1 to 4 The embodiment of the present application provides a non-woven flat bag material stretching device, including a frame 10, a plurality of pressing assemblies 20, a plurality of clamping assemblies 30 and a pressing assembly 40, wherein the first rotating roller 11, the second rotating roller 12 and the first bracket 13 are installed on both sides of the top of the frame 10, and a transmission gap is arranged between the first rotating roller 11 and the second rotating roller 12 on one side of the frame 10; the pressing assembly 20 includes a first driving member 21 and a pressing plate 22, the first driving member 21 is arranged on the first bracket 13, the pressing plate 22 is arranged at the driving end of the first driving member 21, and a recess 221 matching the first rotating roller 11 is opened on the pressing plate 22; the clamping assembly 30 is used to clamp and fix the first rotating roller 11; the pressing assembly 40 is used to press down and stretch the non-woven fabric.

[0036] As can be seen from the above, the embodiment of the present application provides a non-woven flat bag material stretching device. When the fabric needs to be stretched, the non-woven fabric to be stretched passes through the transmission gap between the first rotating roller 11 and the second rotating roller 12 on one side of the frame 10, and passes out from the transmission gap between the first rotating roller 11 and the second rotating roller 12 on the other side of the frame 10. The first rotating roller 11 on one side of the frame 10 is rotated to allow the non-woven fabric to be transported smoothly. At this time, the first driving member 21 is started to move the pressing plate 22 in the direction close to the first rotating roller 11 until the pressing plate 22 presses the non-woven fabric on the first rotating roller 11 through the recess 221, the first rotating roller 11 is clamped and fixed by the clamping assembly 30, and the non-woven fabric is pressed down and stretched by the pressing assembly 40. Therefore, the first driving member 21, the pressing plate 22 and the recess 221 are arranged to press the non-woven fabric arranged on the two first rotating rollers 11, so that the non-woven fabric is firmly fixed on the first rotating roller 11, so that the fabric is difficult to fall off during the stretching process.

[0037] Optionally, in some embodiments, please read Figure 1 to Figure 2 The clamping assembly 30 includes a first slider 31 and a second slider 32. The first slider 31 is arranged on the pressure plate 22. Both sides of the first rotating roller 11 are movably mounted on the frame 10 through the side plates 14. The second slider 32 is elastically arranged on the side plates 14 through the fixing assembly 50. The side of the first slider 31 away from the first rotating roller 11 and the side close to the pressure plate 22 form a first guide surface 311. The second slider 32 is obliquely provided with a second guide surface 321 that matches the first guide surface 311.

[0038] With such arrangement, when it is necessary to clamp and fix the first rotating roller 11, the first driving member 21 is started to move the pressing plate 22 in the direction close to the first rotating roller 11, and the first guide surface 311 contacts the second guide surface 321 until the first slider 31 abuts against the second slider 32, and the pressing plate 22 continues to move in the direction close to the first rotating roller 11, and the two second sliders 32 move in the direction close to the first rotating roller 11 through the first guide surface 311 and the second guide surface 321 until the first rotating roller 11 is clamped and fixed. At this time, the pressing plate 22 presses and fixes the non-woven fabric on the first rotating roller 11 through the recess 221, and the non-woven fabric is pressed and stretched by the pressing assembly 40. Therefore, the arrangement of the first slider 31 and the second slider 32 is used to clamp and fix the two ends of the first rotating roller 11, so that when the pressing assembly 40 presses and stretches the non-woven fabric, the first rotating roller 11 is difficult to rotate, and the non-woven fabric is difficult to loosen, thereby improving the stretching effect of the pressing assembly 40.

[0039] Optionally, in some embodiments, see Figures 2 to 3The pressing assembly 40 includes a second bracket 41, a second driving member 42 and a pressure roller 43. The second bracket 41 is arranged on the frame 10, the second driving member 42 is arranged on the second bracket 41, and the driving end of the second driving member 42 is rotatably connected to the pressure roller 43 through a rotating shaft.

[0040] With such arrangement, when it is necessary to stretch the fixed nonwoven fabric, the second driving member 42 is started, the pressure roller 43 is moved downward until it contacts the nonwoven fabric, and the pressure roller 43 is continued to be moved downward to press down and stretch the nonwoven fabric. The user can adjust the stretching length by changing the pressing length. Therefore, the second bracket 41, the second driving member 42 and the pressure roller 43 make it convenient for the staff to stretch the nonwoven fabric.

[0041] Optionally, in some embodiments, see Figure 4 The fixing assembly 50 includes a fixing frame 51 and a spring 52 . The fixing frame 51 is disposed on the side plate 14 . One end of the spring 52 is connected to the fixing frame 51 , and the other end is connected to the second slider 32 .

[0042] With such an arrangement, after the nonwoven fabric is stretched, when it is necessary to convey the stretched nonwoven fabric, the first driving member 21 is started to move the pressure plate 22 away from the first rotating roller 11, and the first slider 31 moves away from the first rotating roller 11 and disengages from the second slider 32. The second slider 32 disengages from the first rotating roller 11 under the pulling force of the spring 52. Therefore, the arrangement of the fixing frame 51 and the spring 52 is used to support the second slider 32 while enabling the second slider 32 to disengage from the first rotating roller 11 when the device conveys the stretched nonwoven fabric, so that it is difficult for the second slider 32 to affect the conveying efficiency of the first rotating roller 11.

[0043] Optionally, in some embodiments, see Figures 2 to 4 The fixing assembly 50 also includes a spring sleeve 53 and a sliding sleeve 54, both of which are sleeved on the spring 52, one end of the spring sleeve 53 is set on the second slider 32, and the other end is slidably connected to the sliding sleeve 54, and the sliding sleeve 54 is set on the fixing frame 51.

[0044] With such arrangement, when the second slider 32 moves, the sliding sleeve 54 slides under the limit of the spring sleeve 53, and the second slider 32 is unlikely to shake during the movement. Therefore, the arrangement of the spring sleeve 53 and the sliding sleeve 54 is used to protect the spring 52 while making it difficult for the second slider 32 to shake during the sliding process.

[0045] Optionally, in some embodiments, see Figure 1 to Figure 2 A motor 15 is installed on the side plate 14 on one side of the frame 10 , and an output end of the motor 15 is connected to the first rotating roller 11 .

[0046] With such arrangement, after the nonwoven fabric is stretched, when it is necessary to convey the stretched nonwoven fabric, the motor 15 is started, the first rotating roller 11 located in the nonwoven fabric output section rotates, and the stretched nonwoven fabric is conveyed. Therefore, the arrangement of the motor 15 facilitates the staff to convey the nonwoven fabric.

[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
