Description

Technical Field

[0001] The present invention relates to the technical field of fiberglass loom weaving, and particularly relates to a cloth rolling and pressing device for a fiberglass loom. Background Art

[0002] In existing fiberglass looms, the cloth rolling structure generally uses a simple smooth roller to press the cloth. This structure is prone to longitudinal wrinkles when weaving some fiberglass fabrics. To solve this problem, in the existing operation method, only the setting position of the cloth pressing smooth shaft and the walking path of the woven cloth are adjusted, so that the cloth pressing smooth shaft always fits the cloth roll with the swing arm rotation center as the center to prevent wrinkles, as shown in the accompanying drawings of the specification Figure 4 However, this setting method cannot well avoid the appearance of wrinkles in the fabric cloth roll. Instead, when wrinkles appear, the area of their appearance will gradually extend and increase, resulting in an irreparable situation, thus increasing the labor intensity of workers and posing a certain danger.

A limiting bolt passes through the limiting hole 29 and is fixedly connected to the upper support arm 11, capable of adjusting the installation angle of the limiting plate 16 to limit the height of the downward swing of the connecting arm 12.

[0025] The cloth winding assembly includes a cloth winding air shaft 8 and left and right support bearing seats 21 and 22 installed at both ends thereof. The left support bearing seat 21 is vertically and fixedly installed inside the left bearing seat 3 and forms a certain interval therewith; the right support bearing seat 22 is vertically and fixedly installed inside the right bearing seat 4, and there is also a certain interval distance between it and the right bearing seat 4, which is convenient for disassembly and installation. The left and right ends of the cloth winding air shaft 8 are respectively rotatably installed in the left and right support bearing seats. At the left and right ends of the cloth winding air shaft 8, corresponding left end sleeves 23 and right end sleeves 24 are fixedly installed respectively to form installation and fixation for the cloth winding air shaft 8. The cloth winding air shaft 8 is parallel and closely attached to the cloth pressing and polishing shaft 7 and is located on the front side of the cloth pressing and polishing shaft 7.

[0026] The driving assembly is installed at the front part of the outer side wall of the right frame 2 and includes a driving motor 9 and a speed reducer 10, both of which are fixed to the right frame 2 through mounting seats. The output end of the driving motor 9 is fixedly connected to the input end of the speed reducer 10 for mutual transmission; a driving sliding shaft 25 is fixedly sleeved at the end of the output shaft of the speed reducer 10. At the same time, a spring 26 is sleeved outside the output shaft of the speed reducer 10.

The movable end of the above-mentioned driving sliding shaft 25 passes through a ball bearing 27 installed on the right bearing seat 4 and is detachably and fixedly connected to the right end sleeve 24 at the right end of the cloth winding air shaft 8 through a key to drive the cloth winding air shaft 8 to rotate to realize cloth winding.

[0027] The specific working principle is as follows: When the device is in use, first, adjust the position of the adjusting bolt 20 in the adjusting notch 19 on the connecting plate 13, so as to rotate the connecting plate 13, and adjust the bending direction of the rubber bending roller 6 to ensure that the bending arc direction in the rubber bending roller 6 is downward. The woven fiberglass cloth 30 is led out from the upper cloth roller, and when passing through the cloth pressing assembly, it needs to enter from the inner side of the bending arc surface of the rubber bending roller 6 and exit from the bending convex surface. The fiberglass cloth 30 is expanded outward through the convex surface of the rubber bending roller 6, and the tiny wrinkles on the fiberglass cloth 30 are stretched out; then it passes under the cloth pressing light shaft 7 and enters the cloth winding air expanding shaft 8 in a flat state; the cloth winding air expanding shaft 8 realizes active cloth winding under the drive of the drive motor 9 and the speed reducer 10. The cloth pressing light shaft 7 is located between the cloth winding air expanding shaft 8 and the rubber bending roller 6, rotates along with the rotation of the cloth roll, and plays a role in pressing the entire cloth roll under the action of the rubber bending roller 6, the left and right connecting arms 12, the cloth pressing light shaft 7, its own gravity and the cloth winding tension; as the cloth roll increases, the connecting arm 12 drives the cloth pressing light shaft 7 and the rubber bending roller 6 to swing upward flexibly, and the cloth pressing light shaft 7 always clings to the cloth roll, and its rotation direction is the same as the moving direction of the fiberglass cloth 30. Through the cloth pressing light shaft 7, a large wrap angle between the rubber bending roller 6 and the fiberglass cloth 30 is ensured. When the completed cloth roll needs to be disassembled and replaced, the driving slide shaft 25 is pulled out from the right end sleeve 24 at the right end of the cloth winding air expanding shaft 8, and the cloth roll together with the cloth winding air expanding shaft 8 and the support bearing seat is disassembled and replaced; after replacing the new cloth winding air expanding shaft 8, the driving slide shaft 25 is reset by docking under the action of the spring 26 and fixed to the right end sleeve 24 again, so as to continue to drive the new cloth winding air expanding shaft 8 to wind the cloth. During the above replacement process, after the cloth roll is disassembled, the cloth pressing light shaft 7 and the rubber bending roller 6 will drive the connecting arm 12 to swing downward under the action of their own gravity. At this time, the connecting arm 12 will be blocked by the limiting post 17 on the limiting plate 16, restricting its lower swing position to facilitate the replacement and installation of the new cloth winding air expanding shaft 8.

[0028] Finally, it should be noted that the description of the above embodiments is only used to illustrate the technical solutions of the present invention, and is not a limitation to the present invention. The present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also belong to the protection scope of the present invention.
