The invention discloses a partition comber board for jacquard weaving and a mounting method, and belongs to the technical field of jacquard weaving machinery. The partition comber board is characterized in that a partition comber board body (5) is divided into a comber board front region (501) and a comber board rear region (502) by a lateral center line; meshes in the partition comber board body (5) are numbered according to natural numbers from the left part to the right part in sequence; meshes numbered according to odd numbers are odd number meshes (3); meshes numbered according to even numbers are even number meshes (4); the odd number meshes (3) are formed in the comber board rear region (502); the even number meshes (4) are formed in the comber board front region (501); earth beam warp yarns (1) are drafted in the comber board rear region (502); warp beam warp yarns (2) are drafted in the comber board front region (501). The partition comber board can ensure that the earth beam warp yarns and the warp beam warp yarns are arranged according to a 1:1 sequence, and meanwhile can keep uniform and stable tension of the earth beam warp yarns and the warp beam warp yarns.

The invention discloses an orthopedic surgery aid in the technical field of medical auxiliary devices. The orthopedic surgery aid comprises a sliding rod, a slideway is arranged on the inner wall of the sliding rod, trench teeth are arranged at the bottom of the sliding rod, a supporting block is slidably arranged in the middle of the sliding rod, a sliding plate is arranged at the bottom of the supporting block and slidably connected with an adjusting rod, an annular connection block is fixedly connected at the end of the adjusting rod, an oval ring is fixedly connected in the middle of the annular connection block, four rubber blocks are uniformly connected on the outer wall of the connection block slidably, the top of each rubber block is slidably connected with a pulling hook handle, the side wall of each pulling hook handle is fixedly connected with a linear limiting plate, a pulling hook plate is fixedly connected at the end of each pulling hook handle, and a thread is connectedin the middle of each pulling hook plate in a threaded manner. The orthopedic surgery aid can quickly adjust and position pull hooks and is balanced and stable in tension, manpower-saving, free of blocking doctor's operation and sight and capable of cooperating with multiple groups of pull hooks to realize good effect.

The present application relates to a fabric and a device for producing the fabric, comprising a plurality of loop-shaped yarns distributed along the weft direction of the fabric, the loop-shaped yarns are interlocked with each other, a part of the yarns are made of real silk, and the yarns are made of real silk. The remainder of the thread is made of less expensive materials, with yarns made from silk and yarns made from less expensive materials staggered along the weft of the fabric. The present application has the advantages of blending silk and lower-priced materials into fabrics, so that the woven fabrics are less expensive than pure silk fabrics, and have a similar touch and appearance to silk fabrics, making the fabrics easier to sell , thereby increasing the proportion of fabrics in the market.

The invention discloses an air-jet loom. The air-jet loom comprises a frame, a let-off mechanism, a shedding mechanism, a weft insertion mechanism, a beating-up mechanism, a winding mechanism, a warp loosening mechanism and a pneumatic tuck-in mechanism. The frame comprises wall plates, a supporting retainer and a middle support. By reasonable allocation of the wall plates, integrality of the air-jet loom can be improved beneficially; by reasonable allocation of the beating-up mechanism, balancing performance of the beating-up mechanism can be beneficially improved so as to increase beating-up speed of the beating-up mechanism; by reasonable allocation of the winding mechanism, an upper winding pressure roller and a lower winding pressure roller can be lift up at the same time; by reasonable allocation of the warp loosening mechanism, an eccentric adjusting block can slide along a horizontal side groove in an eccentric adjusting seat so as to change eccentricity, and warp loosening quantity can be adjusted according to different fabric requirements; by reasonable allocation of the pneumatic tuck-in mechanism, wefts can be smoothly guided into a stretch nozzle and accurately and stably fed into a cutter opening of the air-jet loom, and excellent tuck-in effects are achieved.

The invention relates to an automatic T-shaped framework small motor rotor winding device. A winding feeding mechanism and a winding driving mechanism are arranged on a working bed plate; the winding feeding mechanism has a secondary feeding structure and comprises a feeding motor and a flying fork head driven by the secondary feeding structure, and the feeding motor drives the flying fork head towards the right to realize primary feeding by a first compression spring and continuously drives the flying fork head towards the right to realize secondary feeding by a second compression spring; a winding end air cylinder is arranged on an outer frame of the working bed plate, a piston of the winding end air cylinder is connected to a tooling fixing plate, a winding end guide pin is arranged on the tooling fixing plate, and the winding end guide pin is adaptive to a metal reversing sheet of a small motor rotor. In the invention, the winding end guide pin is utilized to wrap the front end of the metal reversing sheet and is combined with the secondary feeding of the flying fork head to realize the full-automatic winding of a T-shaped framework of the small motor rotor, and artificial winding is not needed, so that the labor intensity of workers is reduced, the production efficiency is greatly improved, and the pulling force of a tensioner in the winding process is uniform and stable, therefore, the winding quality is stable and unified.
