Description

Technical Field

[0001] The utility model belongs to the technical field of textile fabric production equipment, in particular to a textile fabric drawing equipment. Background Art

[0002] Drawnwork is a type of embroidery, also known as "lace". It is made by knitting fine yarn or linen or cotton cloth and removing the warp or weft of the pattern according to the design, and then connecting them to form a hollow decorative pattern, or using carved embroidery and patchwork to make various tablecloths, curtains, tray mats, handkerchiefs, chair backs, clothing and other daily necessities. Drawnwork requires drawing equipment, which greatly improves the efficiency of drawing by hand.

[0003] After searching, the patent with publication number CN214613036U discloses a textile fabric drawing equipment, including a base, a support plate fixedly connected to the top of the base, a cross bar fixedly connected to the side of the support plate, a blocking block fixedly connected to one end of the cross bar, a sliding sleeve movably sleeved on the cross bar, a fixed block fixed to the bottom of the sliding sleeve, a moving groove provided at the bottom of the fixed block, and a moving block slidably installed in the moving groove. The utility model has a reasonable structure. When the fastening bolt and the control knob are rotated, the front and rear positions and the left and right positions of the drawing roller can be adjusted respectively. When the limit rod is pressed, the connecting sleeve will be loosened, and then the angle of the drawing roller can be adjusted by rotating the connecting sleeve, so that the drawing roller can be adjusted to any position of the fabric, and the staff no longer needs to frequently rotate the fabric or walk back and forth, which saves time and effort and improves the speed of drawing work.

[0004] However, when fixing the fabric on the existing drawing equipment, it is necessary to press the horizontal plate to keep the tension spring in a squeezed state. After the corners of the fabric are fixed to the four horizontal plates, the horizontal plates can be released at the same time. Under the elastic force of the tension springs, the horizontal plates will bounce, straighten the fabric and position it in the center of the placement plate. However, when operated by a single person, it is difficult to press multiple horizontal plates and turn the fixing bolts to fix the fabric at the same time, which is inconvenient to use and the position of the fabric is prone to deviation. In addition, it takes a lot of time to fix the corners of the fabric by turning the fixing bolts to drive the rubber block to move down. Summary of the invention

[0005] The purpose of the utility model is to provide a textile fabric drawing device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a textile fabric drawing equipment, comprising a workbench, a gantry frame is fixedly connected to one side of the workbench, a bearing plate is fixedly connected between four supporting legs of the workbench, a stretching assembly is provided on the top surface of the bearing plate, a fixing assembly is provided on the top surface of the stretching assembly, a drawing assembly is provided in the middle of the gantry frame, and four through slots are opened on the top surface of the workbench;

[0012] Preferably, the drawing assembly comprises a worm rotatably connected to one side of the gantry, one side of the worm is meshed with a worm wheel, and a rotating shaft is fixedly connected to the middle of one side of the worm wheel.

[0013] Preferably, two connecting arms and an electric push rod are respectively provided in the middle of the rotating shaft, and two sliding grooves are provided on the outer side of one end of the rotating shaft away from the worm gear.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] After the fixing component 5 of the utility model fixes the edge corner of the fabric, the first motor is started, the output end of the first motor drives the rotating seat to rotate, the rotating seat drives the movable rod to move in a straight line along the through groove, and the movable rod drives the horizontal plate at the top to move synchronously. Because the rotating seat will drive the four movable rods to move synchronously when rotating, the four horizontal plates will approach or move away from each other at the same time under the drive of the first motor, so that the fabric can be stretched at the same time and the fabric can be automatically located in the middle of the workbench. It is convenient for one person to operate and easy to use.

[0018] When the utility model is used, the edge of the fabric to be fixed is placed under the extrusion block, and then the active arm is moved from a horizontal state to a vertical state. The active arm will drive the driven arm to move through the connecting rod, and the driven arm is rotated from an initial vertical state to a horizontal state. At this time, the driven arm drives the extrusion block to clamp and fix the fabric on the top surface of the horizontal plate. The structure utilizes the dead points of the active arm and the driven arm to clamp and fix the fabric. If the active arm is not rotated, the extrusion block will not loosen the fabric. This fixing method only requires rotating the active arm 90° to quickly fix the fabric, effectively speeding up the fixing speed of the fabric. BRIEF DESCRIPTION OF THE DRAWINGS
