Description

Technical Field

[0001] The present application relates to the field of looms, and in particular to a temple device for a loom. Background Art

[0002] In order to solve the problem of the reduction of the cloth width caused by the tension of the warp and weft yarns, temples are usually provided on both sides of the loom. The temple device currently used in looms adopts a double-row thorn ring type upper-mounted temple, and the front and rear two sets of thorn ring shafts / pressing shafts are assembled on the same temple pressing cover.

[0003] In view of the above related technologies, the two rows of thorn rings can only be adjusted up and down simultaneously and cannot be adjusted independently. When weaving super-fine and dense varieties, the shrinkage force of the cloth surface is large, and the thorn rings of the temple are required to provide a large frictional force. However, the yarn is very thin, and the above temple device is likely to cause the cloth edge to tear. Summary of the Invention

[0004] In order to improve the problem that the two rows of thorn rings cannot be adjusted independently and cause the cloth edge to tear, the present application provides a temple device for a loom.

A vertical second guide rail is fixedly connected to the first pressing cover, and a second pressing cover is slidably connected to the second guide rail, and the second pressing cover slides vertically along the second guide rail; a first vertical positioning bolt and a second vertical positioning bolt are arranged through the first pressing cover for locking the first pressing cover and the second pressing cover; both the first pressing cover and the second pressing cover are provided with pressing shafts, and a plurality of thorn rings are sleeved on each pressing shaft, and each pressing shaft can slide along the cloth width direction.

[0007] By adopting the above solution, the first pressing cover realizes lifting through the first guide rail and the first vertical positioning bolt, and further realizes the lifting of the pressing shaft connected to itself; the second pressing cover realizes lifting through the second guide rail and the second vertical positioning bolt, and further realizes the lifting of the pressing shaft connected to itself. The pressing shaft close to the cloth fell is defined as the front-row pressing shaft, and the pressing shaft far from the cloth fell is defined as the rear-row pressing shaft. By independently adjusting the front and rear two pressing shafts and the thorn rings, the force on the cloth edge is improved, and the purpose of solving the cloth edge tearing is achieved. Adjust the front and rear two pressing shafts respectively. Adjust the front-row pressing shaft to increase the cloth wrapping angle, prevent the cloth surface from shrinking back, stabilize the cloth fell, and reduce the rebound amount of the heddle yarn. Adjust the rear-row pressing shaft to reduce the tension change between the front and rear two pressing shafts and avoid the cloth edge from breaking, so as to ensure the stable and efficient operation of the machine.

[0008] Preferably, a first positioning hole is provided at the position of the first vertical positioning bolt corresponding to the first gland, and a second positioning hole is provided at the position of the second vertical positioning bolt corresponding to the first gland. Both the first positioning hole and the second positioning hole are vertically provided.

[0009] By adopting the above scheme, the first vertical positioning bolt cooperates with the first positioning hole, and the second vertical positioning bolt cooperates with the second positioning hole, realizing the lifting of the first gland and the lifting of the second gland respectively.

[0010] Preferably, transverse positioning holes are provided at the positions of the respective pressing shafts corresponding to the first gland and the second gland. The transverse positioning holes are all arranged along the width direction of the fabric width. Transverse positioning bolts are respectively inserted through the first gland and the second gland at the positions corresponding to the transverse positioning holes, and the transverse positioning bolts are threadedly connected to the pressing shafts.

[0011] By adopting the above scheme, the pressing shaft realizes adjustment in the width direction of the fabric width through the transverse positioning bolts.

[0012] Preferably, a locknut bolt is threadedly connected to the first gland, and the locknut bolt abuts against the first vertical positioning bolt.

[0013] By adopting the above scheme, the locknut bolt abuts against the side wall of the first vertical positioning bolt, and the locknut bolt prevents the first vertical positioning bolt from loosening, improving the stability of the first gland.

[0014] Preferably, a locknut is threadedly connected to the locknut bolt, and the lower end of the locknut abuts against the temple seat.

[0015] By adopting the above scheme, the locknut further improves the stability of the locknut bolt, reduces the probability of the locknut bolt loosening, and improves the position stability of the first gland.

[0016] Preferably, a clamping block is bolted to the cloth support plate.

[0017] By adopting the above scheme, the cloth support plate is fixed to the loom frame through the clamping block, facilitating the installation and debugging of the temple device.

[0018] In summary, the present application has the following beneficial effects:
