The transmission structure of the loom of the embodiment simplifies the transmission structure of the original loom equipment, reduces transmission parts, lightens the whole weight of the structure, reduces the structural load, reduces the reciprocating impact born by the transmission structure of the whole loom, and is more beneficial to the high-speed operation of the loom equipment.

In the transmission structure of the loom of the present embodiment, the motor 10 is used as the only driving device to drive the operation of the whole transmission structure, and the motor 10 is preferably a switched reluctance motor. The motor 10 outputs power through a motor shaft 1001, and the power is transmitted to the main transmission shaft 100 through the meshing engagement of the first gear shaft 101 and the second gear 112.

In this embodiment, the clutch mechanism at the end of the motor shaft 1001 can make the transmission structure of the loom reach the normal working state quickly, and can brake quickly in case of power failure, so as to avoid the phenomena of disordered opening, broken yarn or defective cloth when the weaving stops. In a conceivable real-time mode, the clutch mechanism is an electromagnetic clutch device, and the working principle is as follows:

when the transmission mechanism of the loom starts to work, the motor 10 is started, the motor 10 needs a period of starting time under a general condition, so that the power gradually climbs to a working condition that the rotating speed and the torque are normal, in the embodiment, when the motor is started, the electromagnetic clutch device is controlled by the control end to be not electrified, the electromagnetic clutch device is not attracted, so that the braking structure is not separated from the motor shaft 1001, the braking on the motor shaft 1001 is kept, the motor shaft 1001 is completely released after the motor 10 is started for a period of time, and at the moment, because the motor 10 passes a period of starting time and the clutch mechanism applies load to the motor shaft 1001, the motor shaft 1001 can reach the normal rotating speed, namely the torque at the moment of releasing the motor shaft 1001, so that when the loom weaves the first weft, the beating-up and weft insertion are in a normal weaving state, and the weaving requirement of fabrics with high weft density and cloth cover quality is met.

When power failure occurs, the electromagnetic clutch device is powered off instantly and is not attracted any more, and the electromagnetic clutch device restores the braking state of the motor shaft 1001, so that braking is realized immediately when power failure occurs, and the phenomena of disordered opening, yarn breakage or defective cloth and the like are avoided.

In the embodiment, the power of the main transmission shaft 100 is continuously transmitted to the first cam shaft 131 and the second cam shaft 132 through the first gear 111, the second gear 112, the first large gear 121 and the second gear 112, and further the rapier head transmission mechanism connected with the first cam shaft 131 and the second cam shaft 132 is driven to move, the rapier head transmission mechanism is a mechanism for weaving weft in the weaving machine, wherein the rapier head is included, and the weft is driven to move by the reciprocating motion of the rapier head, so that the weaving is realized.

Further, the rotation of the first cam shaft 131 and the second cam shaft 132 is used for transmitting power to a mechanism for beating up in the loom apparatus for bringing the beating-up mechanism into reciprocating motion.

In addition, related mechanisms for realizing the opening operation, such as a dobby opening mechanism and a jacquard opening mechanism, exist in the weaving machine, and in the embodiment, the power transmission of the related mechanisms for realizing the opening operation is respectively realized through a gear transmission assembly and a power steering mechanism.

As an alternative embodiment of this embodiment, the clutch mechanism includes a friction disc 205 and a first brake disc 211; the motor shaft 1001 is provided with an encoder rotor 202 and further comprises an encoder 203, and the encoder 203 is matched with the encoder rotor 202; first gear shaft 101 tip is provided with bearing cap 204, friction disc 205 sets up in bearing cap 204 one side, friction disc 205 with first gear shaft 101 fixed connection, friction disc 205 sets up with first brake disc 211 relatively, first brake disc 211 one side is provided with coil base 206, be provided with first brake coil 221 and spring 207 on the coil base 206, first brake coil 221 with first brake disc 211 cooperation of magnetic attraction, spring 207 with first brake disc 211 offsets.

In the present embodiment, which is a preferred mode of the clutch mechanism, when the transmission structure of the loom is powered on, the motor 10 is started, and the motor 10 provides torque to the motor shaft 1001, so that the motor shaft 1001 rotates or has a tendency to rotate, at this time, the first brake coil 221 on the coil base 206 and the first brake disk 211 are in a non-attracted state, and the first brake disk 211 is pushed by the pushing force of the spring 207 to push the first brake disk 211 to press the friction disk 205, and press the friction disk 205 to a state abutting against the bearing cover 204, and keep for a very short period of time. Since the first brake disk 211 is in a braking state at this time, in this period of very short time, the motor 10 is started in a state of being subjected to a large load, the encoder 203 and the encoder rotor 202 detect that the motor shaft 201 rotates by a certain angle, generally, the motor shaft 201 can rotate by 90 degrees optionally, the corresponding time is about 30 milliseconds, and at this time, the first brake coil 221 is powered. After the first brake coil 221 is powered, the first brake coil 221 is magnetically attracted to and engaged with the first brake disc 211, and the friction disc 205 is separated from both the bearing cover 204 and the first brake disc 211, so that the load of the motor shaft 201 is instantaneously eliminated.

In the process, the load is increased when the motor 10 is started, and the load is eliminated in a very short time, so that the rotating speed of the motor shaft 1001 and other parts in the loom transmission structure connected with the motor shaft 1001 reaches the required rotating speed of the normal weaving state of the loom equipment in the very short time when the motor 10 is started, generally 600 revolutions per minute, and the beating-up and weft insertion are in the normal weaving state when the loom equipment weaves a first weft, so that the weaving requirement of weaving a fabric with high weft density and high cloth surface quality is met.

In this embodiment, the magnitude of the braking load can be adjusted by adjusting the elastic force of the spring 207, for example, by replacing the spring 207 to adjust the thrust of the spring 207 on the first brake disc 111, so as to change the pressure of the first brake disc 211 on the friction disc 205, thereby adjusting the braking effect.

Secondly, the clutch mechanism of this embodiment also can play better power-off protection effect when the outage. When the power is cut off, the first brake coil 221 immediately releases the first brake disc 211, and the first brake disc 211 pushes the first brake disc 211 to press the friction disc 205 under the thrust of the spring 207 and press the friction disc 205 against the bearing cover 204, so that the first gear shaft 101 fixedly connected with the friction disc 205 achieves a braking effect. Therefore, the motor shaft 1001, the first gear shaft 101 connected with the motor shaft 101 and other related transmission structures in the transmission structure of the weaving machine can be ensured to realize braking immediately when power is cut off suddenly, and phenomena of disordered opening, yarn breakage or defective cloth and the like are avoided.

And in this embodiment, directly set up encoder rotor 202 on motor shaft 1001 to correspond the encoder 203 that sets up and encoder rotor 202 matching, make motor shaft 1001's turned angle can be by direct detection, do not exist because of the transfer chain is longer, the accumulative clearance is great, produce the condition of great angle error when leading to measuring, greatly promoted the measuring precision, and then promoted the stability when starting mechanism uses.

By combining the above embodiments, the braking effect of the motor 10 can be further improved, and the braking self-locking function before the motor 10 is started is achieved.

Conceivably, when the fan blade base 209 rotates along with the motor shaft 201, the air can be driven to flow, so as to take away heat generated by the motor 10 during operation, thereby achieving the cooling effect.
