Menstruation machine
With the development of shuttleless looms, warping machines have become necessary auxiliary equipment. The warping process includes machine-based warping and machine-down warping. 1. The role of the warping machine In the fabric industry, the automatic warping machine is the main equipment that replaces manual operation with machinery in the warping process, and can be used under the warping machine or on shuttle looms or shuttleless looms. This machine has a wide range of applications and reliable performance. It is suitable for tying various fine, medium and coarse fabrics such as cotton, wool and linen. It is also suitable for tying warp beams with or without separate twists. It can improve work efficiency by 3 to 5 times, and the quality of knotting is reliable. 2. Structural performance and technical requirements of the warp tying machine (1) Yarn measuring mechanism: This mechanism ties knots one by one to ensure that the upper and lower layers of warp yarns are in the correct position so that the yarn picking needle can accurately pick the spinning yarn and advance automatically. The machine head and pull through the yarn layer. (2) Tension mechanism: This mechanism facilitates accurate yarn picking and fixing the yarn position, and gives a certain tension to the spinning yarn. It is necessary when the twist is not divided, but it does not work when the twist is divided and should be removed. (3) The twisting mechanism: This mechanism is set up to prevent twisting, that is, the spinning yarns are arranged in order to form knots. (4) Yarn-picking mechanism: The yarn-picking mechanism picks the spinning yarn to the secondary yarn-picking position of the identification needle through a yarn-picking needle or a brush to ensure the accuracy of the yarn-feeding by the identification needle. (5) Double yarn prevention mechanism: The function of the double yarn prevention mechanism is to control double yarns by preventing double yarn hooks up and down. If the yarn picking needle picks up the double yarn prevention hook, it can prevent the double yarn from being sent to the knot forming area. (6) Double yarn identification mechanism: The function of this mechanism is to further identify whether the warp yarn entered by the yarn picking needle or brush yarn picking is set as a single piece, and is a favorable barrier to prevent double yarns from forming knots. (7) Single yarn knotting mechanism: This mechanism is set up after yarn picking to prevent a certain layer of single yarn from being pulled into the knotting area to form knots. (8) Knotting and hooking mechanism: The main function of this mechanism is to further transport the upper and lower warp yarns to the knotting area, and at the same time fix the yarn position to facilitate the yarn clamping pliers to grasp the spinning yarn. (9) Yarn clamping and yarn cutting mechanism: This mechanism further clamps the spinning yarn firmly, fixes the yarn position and sends it to the knot forming area, and cuts the spinning yarn forward when it is sent to the set position. (10) Knotting and yarn clamping mechanism: This mechanism is set up to facilitate precise knotting. The yarn clamping pliers send the spinning yarn to the knotting yarn clamping area and then automatically fix the spinning yarn in the knotting position to ensure stable knotting. (11) Knotting mechanism: The main function of the knotting mechanism is to rotate the picked upper and lower warp yarns twice through the knotting device to complete the knotting purpose. (12) Knot-taking mechanism: The main function of the knot-taking mechanism is to tighten the knotted loop into a strong knot and pull the knot to the back. (13) Yarn return mechanism: The function of the yarn return mechanism is to remove the yarn ends cut by the scissors and brush them out of the area of the yarn picking mechanism. (14) Overload clutch mechanism: The main function of this mechanism is to automatically disengage the motor worm and transmission worm gear when the transmission load exceeds the design load during the operation of the machine head, thereby ensuring that the transmission components of the machine head are not damaged. (15) The structure and use of the movable frame: The movable frame is the main auxiliary part of the knotting machine head and can be moved in the work area. The yarn clamp adopts a hinged and toothed mechanism. The yarn clamping tightness is adjustable and the clamping It has strong force and reliable yarn clamping. It is equipped with an upper and lower warp skew adjustment mechanism, which is adjustable in height and easy to use. 3. Use of warping machine (1) Fixed use: The whole machine is placed in the reed room for use, and the yarn tail of the machine brown frame and the yarn head of the new warp beam are tied and finished. (2) Mobile use: Push the machine head and front frame into the weaving room, and connect the yarn tail of the machine to the yarn head of the replaced weaving beam at the back of the loom. 4. Maintenance and management of the warping machine (1) When unpacking and starting up, all parts should be lubricated according to regulations. (2) When the machine head is not in use, it should be placed in a special wooden box to prevent dust and collision. It should be cleaned with a soft brush to remove dust and waste yarn ends. (3) The machine should be refueled on time to keep the working parts lubricated, and all sliding parts should be refueled once per shift. The internal parts of the machine head can be refueled once every 3 days, and No. 10 engine oil (HJ-10GB443-64) can be used for the above. It should be noted that the yarn picking needle, identification needle, yarn clamping device, yarn clamping device and knot forming device cannot be refueled to prevent oil contamination of the spinning yarn. The warp tying machine is a sophisticated mechanical equipment and should be carefully maintained. Especially if the warp tying part is slightly bumped or scored, it may damage and break the yarn during warp tying and affect the knot formation. Special personnel should be responsible for the warp tying operation and debugging. . Correct operation and maintenance can ensure the performance of the equipment for a long time and extend the service life of the machine.
