Abstract
Description
Technical Field
[0001] The utility model relates to a reversing shaft tension control device for a trial weaving warping machine, belonging to the technical field of textile machinery. Background Art
[0002] In the textile field, the brake device used in the warping machine is generally an electromagnetic brake device, which mostly includes an electric control cabinet, a brake pad installed in the warping machine, and an electromagnetic brake body. The electromagnetic brake body is connected to the electric control cabinet and the brake pad respectively. The electric control cabinet is used to control the operation of the electromagnetic brake body. The electromagnetic brake body acts on the brake pad to indirectly control whether the warping machine is braked or not. However, there is no tension control device for the defective shaft in the test warping machine reversing device.
[0003] When the trial warping machine finds broken ends, missing ends, untwisted yarns and other problems, it is necessary to reverse the shaft to deal with the defective shaft. When dealing with the defective shaft, it is necessary to manually use wood or paper cores to increase the friction on the weaving shaft to tension the yarn. It is difficult to control the tension. If the tension is too small, the yarn is easy to touch the ground and cause contamination. If the tension is too large, it is easy to break, which affects product quality and work efficiency. Utility Model Content
[0004] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a tension control device for a trial weaving warping machine, thereby eliminating the inconvenience and potential safety hazards caused by manually increasing the tension, avoiding the occurrence of loose warps, and improving product quality and work efficiency.
[0005] The utility model describes a reverse shaft tension control device for a trial weaving warping machine, comprising a cylinder, an air pump, a solenoid valve, an adjusting rod, a first fixed bracket, a brake belt and a control device. The cylinder, the solenoid valve and the air pump are connected in sequence through pipelines, the solenoid valve is electrically connected to the control device, one end of the adjusting rod is hinged to the piston rod in the cylinder, and the other end is hinged to the first fixed bracket. An adjusting hole is arranged on the adjusting rod, one end of the brake belt is fixedly connected to the first fixed bracket, and the other end bypasses the weaving shaft chuck and passes through the adjusting hole to be fixedly connected to the adjusting rod.
[0006] Pressurized gas is input into the cylinder through the air pump and the solenoid valve to push the piston rod outward, thereby driving the adjusting rod to rotate around the first fixed bracket, increasing the encirclement angle of the brake belt to the weaving shaft chuck, and increasing the friction between the brake belt and the weaving shaft chuck. The weaving shaft chuck connects the control device to the weaving shaft, and applies appropriate pressure to make the yarn tension on the weaving shaft meet the production requirements. The shaft can be repeatedly reversed to deal with defective shafts, which can more effectively deal with defective shafts, meet production needs, and improve product quality.
[0007] The number of the adjusting holes is at least two, and the adjusting holes are arranged along the length direction of the adjusting rod. Different adjusting holes can achieve different tensioning degrees, thereby expanding the adjustment range.
[0008] A cylinder ring seat is arranged on one end of the cylinder away from the piston rod, and a second fixing bracket is arranged on the wall plate corresponding to the cylinder ring seat. By arranging the cylinder ring seat and the second fixing bracket, the cylinder is fastened to ensure safety.
[0009] The first fixing bracket and the second fixing bracket are both provided with pins to prevent the cylinder ring seat or the adjusting rod from falling off from the fixing bracket.
[0010] The control device comprises a box body, and an air pressure display window and an air pressure switch are arranged on the box body. By arranging the air pressure switch, the start and stop of the air cylinder can be controlled remotely, and by arranging the air pressure display window, the pressure value can be displayed in real time, so as to better control the tension state of the yarn on the weaving shaft.
[0011] The pipeline is provided with an air pressure regulating valve, and the box body is also provided with an air pressure regulating valve button corresponding to the air pressure regulating valve. By adjusting the air pressure regulating valve button, the tension of the yarn on the weaving shaft can be further controlled.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] (1) The utility model realizes tension control of the defective shaft by arranging an air cylinder, an air pump, an electromagnetic valve, an adjusting rod, a first fixed bracket, a brake belt and a control device, thereby eliminating the inconvenience and safety hazards caused by manually increasing the tension, avoiding the occurrence of loose warp, and improving product quality and work efficiency.
[0014] (2) There are at least two adjustment holes, which are arranged along the length of the adjustment rod. Different adjustment holes can achieve different tensioning degrees, thereby expanding the adjustment range.
[0015] (3) An air pressure regulating valve is arranged on the pipeline, and an air pressure regulating valve button is arranged on the box body corresponding to the air pressure regulating valve. By adjusting the air pressure regulating valve button, the tension of the yarn on the weaving shaft can be further controlled. BRIEF DESCRIPTION OF THE DRAWINGS

The brake band 6 uses a glue with a thickness of 5 mm and a width of 40 mm as a friction member to act as a brake. The cylinder 8, the solenoid valve and the air pump are connected in sequence through pipelines. The stroke of the piston rod 2 of the cylinder 8 is 50 mm. The stroke of the piston rod 2 directly determines the tension of the brake band 6. The solenoid valve is electrically connected to the control device. One end of the adjusting rod 4 is hinged to the piston rod 2 in the cylinder 8, and the other end is hinged to the first fixed bracket 5. An adjusting hole 3 is arranged on the adjusting rod 4. One end of the brake band 6 is fixedly connected to the first fixed bracket 5, and the other end bypasses the weaving shaft clamp 7 and passes through the adjusting hole 3 to be fixedly connected to the adjusting rod 4.
[0022] There are three adjustment holes 3 , which are arranged along the length direction of the adjustment rod 4 .
[0023] A cylinder ring seat 9 is arranged on the end of the cylinder 8 away from the piston rod 2, and a second fixing bracket 1 is arranged on the wall panel corresponding to the cylinder ring seat 9.
[0024] Pins are disposed on both the first fixing bracket 5 and the second fixing bracket 1 .

The first fixed bracket 5 and the second fixed bracket 1 are both provided with pins. The cylinder ring seat 9 is mounted on the second fixed bracket 1, and then the pin is installed to lock it to prevent the cylinder 8 ring from slipping out, thereby tightening the entire cylinder 8 as a whole. Pressurized gas is input into the cylinder 8 through the air pump and the solenoid valve to push the piston rod 2 to move outward, thereby driving the adjusting rod 4 to rotate around the first fixed bracket 5, and the encirclement angle of the brake belt 6 to the weaving shaft chuck 7 is increased, and the friction between the brake belt 6 and the weaving shaft chuck 7 is increased, thereby increasing the yarn tension on the weaving shaft.
