Description

Technical Field

[0001] The invention relates to the technical field of air jet looms, and in particular to a novel cloth winding tension control device for a glass fiber loom. Background Art

[0002] During the winding process, existing fiberglass looms typically utilize four rollers: an upper cloth-holding roller, a lower cloth-holding roller, a tension roller, and a winding roller to control the overall fabric tension. This tension control structure is used on fiberglass fabrics with a relatively low weft density. Because the tension roller is located above the lower cloth-holding roller, the fabric passing through the tension roller will pass again along the outer surface of the lower cloth-holding roller. This can easily cause the fabric to slip between the tension roller and the tension roller, resulting in wrinkles and poor fabric quality. Summary of the Invention

[0029] like Figure 1As shown, a novel cloth winding tension control device for a glass fiber loom comprises a frame, an upper cloth pressing roller 104 and its supporting components, a winding roller 103 and its mounting components, a tension roller 105 and its control components. The frame comprises a left wall panel 101 and a right wall panel 102. The upper cloth pressing roller 104, the winding roller 103 and the tension roller 105 are rotatably mounted between the left wall panel 101 and the right wall panel 102, and are arranged parallel to each other. The upper cloth pressing roller 104 is located above the winding roller 103, and the tension roller 105 is located in front of and below the winding roller 103. A left fixed plate 107 and a right fixed plate 108 are also provided at the front upper position of the inner side walls of the left wall panel 101 and the right wall panel 102, respectively. On the inner side walls of each fixed plate, an upper support rod 109, an upper cloth pressing roller pin 110, a tension roller pin 111 and a first mounting hole are provided at specific positions according to production requirements. A pillar 123 is installed in the first mounting hole. The pillar 123 is in the shape of a boss, and a second mounting hole is provided at the center position of its bottom. The top of the boss of the pillar 123 is inserted into the first mounting hole; the upper support rod 109, the upper cloth pressing roller pin 110 and the tension roller pin 111 are all perpendicular to the plate plane where the fixed plate is located.

[0030] Combine Figures 2 to 5 The winding roller 103 is rotatably mounted on the left and right wall panels through its mounting components. The mounting components include seat-fixed bearings 131 located at the left and right ends of the winding roller 103. The seat-fixed bearings 131 are fixedly mounted on the corresponding left wall panel 101 and right wall panel 102 by bolts respectively. The winding roller 103 can rotate around the seat-fixed bearings 131.

[0031] The supporting components of the above-mentioned upper cloth pressing roller 104 include an upper left cloth pressing roller arm 112 and an upper right cloth pressing roller arm 113. The middle parts of the upper left cloth pressing roller arm 112 and the upper right cloth pressing roller arm 113 are each provided with a first support shaft hole. A No. 1 bearing is fixedly installed on the inner side of the first support shaft hole, which is respectively sleeved on the left and right ends of the upper cloth pressing roller 104; the front ends of the upper left cloth pressing roller arm 112 and the upper right cloth pressing roller arm 113 are respectively hinged to the upper cloth pressing roller pin 110 provided on the corresponding fixed plate, so that the upper cloth pressing roller 104 can rotate around the upper cloth pressing roller pin 110; vertical bearings are provided at the rear ends of the upper left cloth pressing roller arm 112 and the upper right cloth pressing roller arm 113 The threaded slot and the vertical threaded slot are open to the rear, and a first spring pull rod 125 is installed in the vertical threaded slot. The upper end of the first spring pull rod 125 is fixedly installed with a tension handle 129, which can be adjusted by rotation to adjust the fixed position of the first spring pull rod 125 in the vertical threaded slot. The lower end of the first spring pull rod 125 is hung with a first tension spring 126, and the other end of the first tension spring 126 is hung on the upper end of the spring hanging plate 130 arranged on the frame; through the joint tensioning action of the above-mentioned first spring pull rod 125 and the first tension spring 126, the upper cloth pressing roller 104 is pressed against the top of the winding roller 103.

[0032] The control components of the tension roller 105 include a left tension roller arm 114, a right tension roller arm 115, a first tension link, and a second tension link. The left tension roller arm 114 and the right tension roller arm 115 are of an obtuse-angle structure as a whole, and are both provided with a second support shaft hole in the middle. A second bearing is fixedly installed in the second support shaft hole, which is respectively mounted on the left and right ends of the tension roller 105; the upper ends of the left tension roller arm 114 and the right tension roller arm 115 are respectively mounted on the tension roller pin 111 provided on the corresponding fixed plate, and are hinged therewith, so that the tension roller 105 can rotate around the tension roller pin 111; a second threaded groove is provided at the lower end of the left tension roller arm 114 and the right tension roller arm 115, and the second threaded groove is open downward. The second spring pull rod 127 is installed in the second threaded slot, and the front end of the second spring pull rod 127 is installed with a tension handle 129, which can adjust the fixed position of the second spring pull rod 127 in the second threaded slot by rotation. The rear end of the second spring pull rod 127 is installed with a second tension spring 128, and the other end of the second tension spring 128 is fixedly connected to the lower end of the spring hanging plate 130 provided on the frame; through the joint tensioning action of the above-mentioned second spring pull rod 127 and the second tension spring 128, the tension roller 105 is pressed tightly against the front and lower part of the winding roller 103.

[0033] The first tension link is mounted on the left side of the tension roller 105 and includes a first connecting rod 116. The upper end of the first connecting rod 116 is hinged to the upper support rod 109 on the left fixed plate 107 through a first joint bearing 118, and the lower end is hinged to the tension roller pin 111 on the left fixed plate 107 through a second joint bearing 119. The second tension link is mounted on the right side of the tension roller 105 and includes a tension sensor 117. The upper end of the tension sensor 117 is hinged to the upper support rod 109 on the right fixed plate 108 through a third joint bearing 120, and the lower end is hinged to the tension roller pin 111 on the right fixed plate 108 through a fourth joint bearing 121. At the same time, a lower connecting arm 122 is mounted on the outer end of the support 123. The lower connecting arm 122 is in the shape of a plum wrench. One end of the lower connecting arm 122 is pinned to the second mounting hole on the support 123 through a roller arm pin 124, and the other end of the lower connecting arm 122 is sleeved on the corresponding tension roller pin 111. The upper end of the corresponding tension roller arm, one end of the lower connecting arm and the joint bearing at the lower end of the corresponding tension link are hingedly mounted on the above-mentioned corresponding tension roller pin 111 from the inside to the outside (i.e., from the end close to the fixed plate to the end away from the fixed plate) in sequence, and are limited and fixed at the outer end of the tension roller pin 111 by a limiting bolt 133, so that the lower connecting arm 122 and the corresponding tension link form a triangular stable support at the tension roller pin 111.

[0034] In the novel cloth winding tension control device for a fiberglass loom, all structures mounted on the left and right fixed plates 107 and 108, with the exception of the first and second tension links, are bilaterally symmetrical about the front-to-back longitudinal center plane of the entire device to ensure synchronization of the entire device. Furthermore, the winding roller 103, upper cloth pressing roller 104, and tension roller 105 are all cylindrical in shape, with the outer diameter of the winding roller 103 being greater than that of the upper cloth pressing roller 104, and the outer diameter of the upper cloth pressing roller 104 being greater than that of the tension roller 105.

[0035] In addition, the above-mentioned glass fiber loom also includes a cloth winding roller 106, which is detachably rotatably installed at the front lower part of the frame, located between the left wall panel 101 and the right wall panel 102 that constitute the frame, and is parallel to the upper cloth pressing roller 104, the winding roller 103 and the tension roller 105.

[0036] Combine Figure 6 As shown, during use, the woven cloth 134 is passed from above the upper cloth pressing roller 104 around the upper cloth pressing roller 104 and enters the take-up roller 103. After passing around the take-up roller 103, it comes out from the upper cross-section of the tension roller 105, and then passes around the outer surface of the tension roller 105 downward to the cloth winding roller 106 to form a cloth roll 132. The winding speed of the cloth winding roller 106 is synchronized with the speed of the woven cloth 134, which is achieved through cloth winding tension control. As can be seen from the figure, the cloth winding tension acts on the tension roller 105 and is applied to the corresponding lower connecting arm 122 and the tension roller pin 111 hinged to the tension link through the tension roller arm. The tension sensor 117 in the second tension link will sense the specific value of the cloth winding tension. By adjusting and controlling the cloth winding speed of the cloth winding roller 106, the required stable cloth winding tension is achieved. At the same time, the pressure exerted by the corresponding second tension spring 128 on the lower end of the tension roller arm causes the tension roller 105 to be pressed against the winding roller 103. When the winding roller 103 rotates, it drives the tension roller 105 to rotate, and the cloth 134 is sandwiched between the two to achieve synchronous movement without slippage, thus solving the problem of wrinkles on the cloth surface.

[0037] Finally, it should be noted that the description of the above-mentioned implementation mode is only used to illustrate the technical solution of the present invention, and is not a limitation of the present invention. The present invention is not limited to the above-mentioned examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
