Description

Technical Field

[0001] The present invention belongs to the technical field of textile machinery, relates to a component mechanism of a rapier loom, and particularly relates to a transmission mechanism of a rapier loom. Background Art

[0002] The rapier loom is currently the most widely used shuttleless loom. In addition to the characteristics of high speed, high degree of automation, and high-efficiency production of shuttleless looms, its positive weft insertion method has strong variety adaptability and can adapt to the weft insertion of various yarns. Moreover, the rapier loom also has obvious advantages in multi-color weft weaving and can produce figured woven products with up to 16 color wefts. With the replacement of shuttle looms by shuttleless looms, the efficiency of looms has been greatly improved, and shuttleless looms have become the development direction of the world textile machinery industry.

[0003] The transmission mechanism of the rapier loom is an essential component of the rapier loom. When yarn breakage occurs during the weaving process of the loom, the warp line needs to be aligned and the broken yarn needs to be processed through the weft finding process, and the weft finding process requires the loom to run at a slow speed. The traditional transmission mechanism has a complex structure, frequent failures under high-speed heavy loads, serious damage to the transmission mechanism, and troublesome maintenance. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a rapier loom transmission mechanism with a simple structure, high transmission efficiency, and convenient for users to disassemble and repair, aiming at the above-mentioned defects of the prior art.

[0005] The object of the present invention is achieved by the following technical solutions. A rapier loom transmission mechanism includes a frame, a motor arranged on the frame, and a transmission mechanism driven by the motor. The transmission mechanism mainly includes a high-speed shaft, a first high-speed gear shaft and a second high-speed gear shaft fixedly arranged on both sides of the high-speed shaft. The input end of the first high-speed gear shaft is connected to the motor. The gear on the first high-speed shaft is meshed and connected with a first beating-up transmission gear. The first beating-up transmission gear is meshed and connected with a first weft insertion transmission gear. The gear on the second high-speed gear shaft is meshed and connected with a second beating-up transmission gear. The second beating-up transmission gear is meshed and connected with a second weft insertion transmission gear. The first beating-up transmission gear and the second beating-up transmission gear are connected to the beating-up mechanism through a transmission shaft and form a rotating pair with the frame. The sides of the first weft insertion transmission gear and the second weft insertion transmission gear facing away from each other are respectively connected to the weft insertion mechanisms on the left and right sides through a transmission shaft and form a rotating pair with the frame. The side of the second beating-up transmission gear away from the beating-up mechanism drives an opening mechanism and a scissors shaft through an open shaft, and a brake is arranged on the open shaft.

[0006] Further, a first pulley and a second pulley are sequentially arranged on the opening shaft from inside to outside. The first pulley is connected to a first driven wheel through a first synchronous belt, and the opening mechanism is connected to the first driven wheel through a transmission shaft. The second pulley is connected to a second driven wheel through a second synchronous belt, and the second driven wheel of the scissor shaft is fixedly connected.

[0007] Further, on the side of the first beating-up transmission gear away from the beating-up mechanism, a resolver for sensing the angular position of the loom main shaft is arranged through a transmission shaft.

[0008] Further, the motor is a switched reluctance motor, which consists of a motor housing, a motor stator and a motor rotor arranged inside the motor housing. The motor rotor is fixedly connected to the input end of the first high-speed gear shaft, and the motor housing is fixedly connected to the side cover on the wallboard.

[0009] The beneficial technical effects of the present invention are as follows: Compared with the prior art, the rapier loom transmission mechanism of the present invention has the characteristics of compact structure, high transmission efficiency and few transmission links, effectively overcoming the disadvantages of the existing rapier loom transmission mechanism, such as complex structure, being not conducive to the high-speed operation of the loom and the transmission structure being easily damaged and not easy to repair. Description of the Drawings

[0010] Figure 1 It is a schematic diagram of the overall structure of the present invention. Detailed Embodiments

[0011] To make those of ordinary skill in the art understand the purpose, technical solution and advantages of the present invention more clearly, the present invention will be further described below with reference to the drawings and embodiments.

[0012] Such as Figure 1As shown in the figure, a rapier loom drive mechanism according to the present invention includes a frame, a motor disposed on the frame, and a drive mechanism driven by the motor. The drive mechanism mainly includes a high-speed shaft 109 and a first high-speed gear shaft 104 and a second high-speed gear shaft 107 fixedly disposed on both sides of the high-speed shaft 109. The input end of the first high-speed gear shaft 104 is connected to the motor. The gear on the first high-speed gear shaft 104 is meshed and connected with a first beating-up drive gear 106. The first beating-up drive gear 106 is meshed and connected with a first weft insertion drive gear 115. The gear on the second high-speed gear shaft 107 is meshed and connected with a second beating-up drive gear 108. The second beating-up drive gear 108 is meshed and connected with a second weft insertion drive gear 114. The first beating-up drive gear 106 and the second beating-up drive gear 108 are connected to the beating-up mechanism 2 through a transmission shaft and form a rotating pair with the frame. The sides of the first weft insertion drive gear 115 and the second weft insertion drive gear 114 facing away from each other are respectively connected to the weft insertion mechanisms 1 on the left and right sides through a transmission shaft and form a rotating pair with the frame. The side of the second beating-up drive gear 108 away from the beating-up mechanism 2 drives an opening mechanism and a scissors shaft 119 through an opening shaft 120. A brake 110 is disposed on the opening shaft 120.

[0013] Referring to Figure 1 As shown in the figure, a first pulley 111 and a second pulley 116 are sequentially disposed on the opening shaft 120 from inside to outside. The first pulley 111 is connected to a first driven wheel 112 through a first synchronous belt 113. The opening mechanism 3 is connected to the first driven wheel 112 through a transmission shaft. The second pulley 116 is connected to a second driven wheel 118 through a second synchronous belt 117. The scissors shaft 119 is fixedly connected to the second driven wheel 118. A resolver 105 for sensing the angular position of the loom main shaft is disposed on the side of the first beating-up drive gear 106 away from the beating-up mechanism through a transmission shaft.

[0014] Referring to Figure 1 As shown in the figure, the motor is a switched reluctance motor. The switched reluctance motor is composed of a motor housing 102, a motor stator 103, and a motor rotor 101 disposed inside the motor housing 102. The motor rotor 101 is fixedly connected to the input end of the first high-speed gear shaft 104. The motor housing 102 is fixedly connected to a side cover 100 on the wallboard.

[0015] During normal operation, the switched reluctance motor is energized, the brake 110 disengages, the motor rotor 101 rotates, driving the first high-speed gear shaft 104, the high-speed shaft 109 and the second high-speed gear shaft 107 to rotate. Then, through the first beating-up transmission gear 106 and the second beating-up transmission gear 108, the beating-up mechanism is driven to rotate. At the same time, the resolver 105 is also driven to rotate to sense the angular position of the loom main shaft, and the shedding shaft 120 is driven to rotate; the second weft insertion gear 114 and the first weft insertion gear 115 drive the weft insertion mechanism 1 to move; the shedding shaft 120 drives the shedding mechanism 3 to move through the first pulley 111, the first synchronous belt 113 and the first driven pulley 112; the shedding shaft 120 drives the scissor shaft 119 to move through the second pulley 116, the second synchronous belt 117 and the second driven pulley 118.

[0016] When the loom brakes, the switched reluctance motor is energized in the reverse direction, the motor rotor 101 is quickly braked, and the loom movement stops. After the loom movement completely stops, the brake 110 brakes, the switched reluctance motor is de-energized, and the loom is in the braking state. The transmission route of the loom during slow movement is the same as that during normal movement of the loom, but the speed is slower than that of normal movement. The loom can move slowly forward and backward.
