Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and in particular relates to a device capable of adjusting the tension of yarns of a textile warp knitting machine. Background Art

[0002] Existing textile machines are used in the process of transporting yarns. Due to the different types of yarns, the tension of the yarns is different. The tension adjustment device cannot freely adjust the tension of the yarns to adapt to different types of yarns. Among them, the "yarn tensioning device for textile machines" disclosed in the application number "CN201820778298.2" is also an increasingly mature technology. The position of the tensioning slide can be changed through the sliding rod on the tensioning slide groove, thereby adjusting the tension of the tensioning device. It also has a hydraulic cylinder that can change the height of the yarn tube to change the relative height between the yarn tubes, thereby adjusting the surface tension of the yarn. However, the device also has the following defects: during the yarn transportation process, when the tension at one end of the yarn is tightened, the yarn that has been transported at the rear end will become loose. When the tension between the straightening end and the transportation end needs to be adjusted, a separate device is required to straighten the subsequent loose yarn in transportation, and the tension of the yarn at different stages cannot be completed synchronously. Utility Model Content

[0003] The utility model aims to provide a device with adjustable yarn tension for a textile warp knitting machine, aiming to solve the problem in the prior art that, during the yarn transportation process, after the tension at one end of the yarn is tightened, the yarn that has been transported at the rear end will become loose, and when the tension between the straightening end and the transport end needs to be adjusted, a separate device is required to straighten the subsequent loose yarn in transportation, and the tension of the yarn at different stages cannot be completed synchronously.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: it includes a wire transmission frame, tension adjustment frames are arranged on both sides of the wire transmission frame, one side of the top of the tension adjustment frame is rotatably connected to a driven gear, one end of the driven gear is fixedly connected to a tension adjustment disk, the middle of the tension adjustment disk is fixedly connected to a tension eccentric rod, one end of the tension eccentric rod is rotatably connected to a lower pressure shaft, an upper sliding groove is opened on the top of one side of the tension adjustment frame, an upper adjusting rack is slidably connected in the upper sliding groove, the upper adjusting rack is meshingly connected to the driven gear, a synchronous motor is embedded in the middle of the outer side of the tension adjustment frame, a driving gear is fixedly installed on the output end of the synchronous motor, and the driving gear is meshingly connected to the upper adjusting rack.

[0005] In an implementation scheme of a device for adjusting the yarn tension of a textile warp knitting machine of the utility model, a sliding groove is opened at the bottom of one side of the tension adjustment frame, a lower adjustment rack is slidably connected in the sliding groove, the lower adjustment rack is meshed with a driving gear, one end of the lower adjustment rack is hinged with an adjustment folding rod, one end of the adjustment folding rod is hinged to the bottom of the other side of the tension adjustment frame, and the middle part of the adjustment folding rod is rotatably connected to an upper adjustment top rod.

[0006] In this solution, when the synchronous motor rotates the driving gear, the lower adjusting rack moves in the lower sliding groove. At this time, the lower adjusting rack pushes the adjusting folding rod to hinge. At this time, the hinge of the adjusting folding rod moves upward, and the upper adjusting top rod moves upward to straighten the cotton thread in transportation, so as to avoid the yarn in the front section being in a relaxed state during transportation due to the transportation speed after the yarn is tightened at one end. The yarn in different transportation sections is adaptively straightened to adjust the tension of the yarn during transportation.

[0007] In an implementation scheme of the utility model of a device for adjusting the yarn tension of a textile warp knitting machine, an upper thread pressing guide wheel is distributed on the surface of the upper adjusting push rod.

[0008] In this solution, the yarn is guided during transportation by the upper pressing wire guide wheel to avoid positional deviation of the yarn during transportation.

[0009] In an implementation scheme of a device for adjusting yarn tension of a textile warp knitting machine of the utility model, a plurality of yarn outlet sleeves are distributed on the top of the wire feeding frame, and mesh holes are opened in the middle of the yarn outlet sleeves.

[0010] In this solution, the yarn is pulled from the yarn outlet sleeve and wound under the lower wire pressing guide wheel, and the transport mesh size of the yarn can be adjusted by replacing the yarn outlet sleeve.

[0011] In an implementation scheme of the utility model of a device for adjusting yarn tension of a textile warp knitting machine, a lower pressing thread guide wheel is distributed on the surface of the lower pressing shaft, and the position of the lower pressing thread guide wheel matches that of the upper pressing thread guide wheel.

[0012] In this solution, during the transportation process, the lower thread pressing guide wheel cooperates with the upper thread pressing guide wheel to adjust the transportation direction of the yarn, so as to avoid position deviation of the yarn during transportation.

[0013] In an implementation scheme of the utility model of a device for adjusting the yarn tension of a textile warp knitting machine, the other side of the tension adjustment frame is rotatably connected with a yarn transport wheel.

[0014] In this scheme, the cotton thread after the tension is adjusted is transported by the yarn transport wheel, so that the yarn is in a uniform speed transport state, thereby improving the stability of yarn transportation.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1) When the driving gear is rotated by the synchronous motor, the driving gear drives the upper adjusting rack and the lower adjusting rack respectively, and the upper adjusting rack and the lower adjusting rack move in the upper slide groove and the lower slide groove respectively, and the upper adjusting rack mobilizes the driven gear meshing with it to rotate the tension adjusting disk, and the tension eccentric rod moves downward and swings, and the lower pressure shaft presses down on the yarn in transportation to adjust the yarn in the yarn transportation stage. At this time, the lower adjusting rack pushes the adjusting folding rod to hinge. At this time, the hinge of the adjusting folding rod moves upward, and the upper adjusting top rod moves upward to straighten the cotton thread in transportation, so as to avoid the yarn being tightened at one end and the front section of the yarn being relaxed during transportation due to the transportation speed. The yarn in different transportation sections is adaptively straightened to synchronously adjust the tension of the yarn during transportation. BRIEF DESCRIPTION OF THE DRAWINGS
