Huixian Xinda Textile Machinery Accessories Co., Ltd. provides 1515/1511 dobby loom parts T49 heald spring legs, textile dobby loom heald lifting parts, textile t50-1 heald spring legs, and 1511/1515 looms adopt vertical heald tension spring device. The installation and adjustment requirements of the heald device need to pay attention to that the front and rear sequence of hanging tension spring should be consistent with the heald frame sequence, and the number of springs used should be determined by the process requirements, The elastic force is adjusted by the expansion and contraction of the bottom bolt. The left and right heald spring hangers (T49) shall be symmetrically installed and parallel to each other according to different reed widths, taking the heald frame center line as the center, so that the heald frame can be lifted and lowered at the same time to avoid unclear opening.
The total length of the heald spring hanger T49 is 317.8mm, and the material is gray pig iron HT15-33. It is used in connection with the T48 heald frame, regardless of the left hand and the right hand. The two are fixed on the front and rear supports of 4312, 4313 or P7 after connection.
One end of the heald tension spring is connected with an adjusting ring. The tension of the tension spring shall be adjusted according to the number of warp threads and the tension. The length of each tension spring and accessories of the same machine shall be basically the same. Explanation on the unclear opening of dobby loom:
1. The specification of the parts of the dobby heald lifting mechanism is not neat, or the degree of abrasion is different, resulting in different lifting heights of heald frames on each page, which affects the clarity of the shed.
2. The heald frame is not leveled, the heald clip is lost, and the warp is loose and sagging; The heald spring t50-1 is loose or has insufficient elasticity, and the lower warp floats up, affecting the clarity of the shed.
3. The moving range of the up and down knives is different, which affects the clarity of the shed.
4. The lifting height of the heald frame of each page changes with the abrasion degree of the tread plate, which affects the clarity of the shed.
5. The lifting heald is too low or loose, the shed height does not meet the requirements, and the warp yarn is loose; The drawdown position of the heald frame is pulled too tight, so that the lower warp clings to the shuttle plate Q2 or 3310 for friction, and the warp loosens during lifting.
6. The tread plate is loose or the opening time is disordered, and the shed opening is not clear.
