Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of net fabric weaving tension adjusting mechanism, belong to textile machinery technical field. BACKGROUND
[0002] At present, the weaving of net fabric or artificial blood vessel is carried out on a special loom, the middle section of the loom is a yarn guide frame, which functions as yarn guiding and gathering; however, there is uneven warp tension during warp feeding, which leads to poor fabric effect and cannot meet the production requirements, increasing production cost. SUMMARY
[0003] The utility model provides a kind of net fabric weaving tension adjusting mechanism for the above prior art, simple structure, ensure that warp tension is uniform during warp feeding, improve fabric effect, save production cost.
[0004] The utility model discloses the technical scheme adopted to solve the above problems is as follows: a kind of net fabric weaving tension adjusting mechanism, including chassis, the chassis front and rear sides symmetrically set side plate, be equipped with the horizontal arrangement import guide roller and export guide roller between two the side plate;The inner wall of side plate is symmetrically set up yarn gathering support, and be equipped with yarn gathering reed between two the yarn gathering support, the yarn gathering reed is equipped with import guide roller import side;The inner wall of side plate is symmetrically set up guide support, and be equipped with guide reed on two the guide support, the guide reed is equipped with export guide roller export side;The guide reed export is equipped with guide rod;Be equipped with floating guide roller between the import guide roller and export guide roller, the floating guide roller is connected with side plate by swing unit, and be equipped with elastic member on the swing unit;Yarn is gathered by the yarn gathering reed, and piece yarn is formed, then is sent into loom weaving by the import guide roller, floating guide roller, export guide roller, guide reed, guide rod;When piece yarn tension is large, swing unit, floating guide roller are driven to swing upwards;When piece yarn tension is small, the elasticity of the elastic member makes swing unit, floating guide roller swing downwards, so that piece yarn tension is uniform.
[0005] The swing unit includes two symmetrically arranged swing rods, one end of the swing rod is hinged to the corresponding side plate, and the other end of the swing rod is connected to the corresponding side plate.
[0006] The chassis is symmetrically provided with wheels at the bottom.
[0007] The elastic member includes two vertically arranged tension springs, one end of the tension spring is fixedly connected to the corresponding swing rod, and the other end of the tension spring is fixed to the inner wall of the corresponding side plate.
[0008] Compared with the existing technology, the advantages of the utility model are: a mesh fabric weaving tension adjustment mechanism with a simple structure, which ensures uniform tension of the warp yarn during the warp feeding process with the cooperation of the floating guide roller and the tension spring, improves the fabric effect and saves production costs.

[0011] In the figure, 1 is the base frame, 2 is the wheel, 3 is the yarn gathering bracket, 4 is the yarn gathering reed, 5 is the inlet guide roller, 6 is the side plate, 7 is the floating guide roller, 8 is the tension spring, 9 is the swing rod, 10 is the yarn guide bracket, 11 is the outlet guide roller, 12 is the yarn guide reed, and 13 is the yarn guide rod. DETAILED DESCRIPTION
[0012] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0013] like Figure 1 、 2 As shown, a mesh fabric weaving tension adjustment mechanism in this embodiment includes a base frame 1 with vertically arranged side panels 6 symmetrically disposed on the front and rear sides of the base frame 1. A horizontally arranged inlet guide roller 5 and outlet guide roller 11 are disposed between the side panels 6 along the yarn conveying direction. The inlet guide roller 5 and the outlet guide roller 11 are respectively mounted between the side panels 6 at their ends. Yarn gathering brackets 3 are symmetrically disposed on the inner walls of the side panels 6. A yarn gathering reed 4 is disposed between the two yarn gathering brackets 3 and is located on the inlet side of the inlet guide roller 5. Yarn guide brackets 10 are symmetrically disposed on the inner walls of the side panels 6. A yarn guide reed 12 is disposed between the two yarn guide brackets 10 and is located on the outlet side of the outlet guide roller 11. A yarn guide rod 13 is provided at the outlet of the yarn guide reed 12. Two symmetrically arranged swinging levers 9 are installed between the two side plates 6. One end of the swinging lever 9 is hinged to the corresponding side plate 6. A floating guide roller 7 is also installed between the inlet guide roller 5 and the outlet guide roller 11. Each end of the floating guide roller 7 is fixedly connected to the other end of the corresponding swinging lever 9. A vertical tension spring 8 is installed at the bottom of each swinging lever 9. One end of the tension spring 8 is fixedly connected to the swinging lever 9, and the other end is fixedly connected to the corresponding side plate 6. During weaving, the yarn is fed from the creel in the direction of the arrow and gathered by the gathering reed to form a yarn sheet (warp). The yarn sheet then passes through the inlet guide roller, floating guide roller, outlet guide roller, yarn guide reed, and yarn guide rod and is fed into the loom for weaving. During the weaving process, changes in yarn sheet tension cause the floating guide roller and tension spring to swing about the hinge point. When the yarn sheet tension is high, the swinging lever and floating guide roller swing upward. When the yarn sheet tension is low, the elasticity of the tension spring causes the swinging lever and floating guide roller to swing downward, thus maintaining a stable yarn sheet tension.
[0014] The chassis is symmetrically provided with four wheels 2, facilitating the movement of the chassis 1.
[0015] The application has simple structure, under cooperation of the floating guide roller and the tension spring, ensures even tension of the warp yarn during the warp yarn feeding process, improves fabric effect and saves production cost.
[0016] In addition to the above-mentioned embodiments, the utility model also includes other implementation manners, and the technical solutions formed by using equivalent transformation or equivalent replacement should fall within the protection scope of the utility model claims.
