Problems solved by technology

A rotary screen printing machine is usually composed of five parts: a cloth feeding device, a printing head, a drying device, a cloth falling device, and a weft adjusting device. There are many paths and a large space, and of course the price is also very expensive; in addition, there will be a certain degree of weft bending or weft skew before the fabric is set, so the weft skew must be corrected and sorted before the fabric is needled, so as to ensure The fabric achieves the best setting effect after high-temperature setting. The existing weft adjustment device usually adopts screw drive or chain drive. The transmission stability is poor and certain impact and noise will be generated during work. Therefore, it is necessary to provide a Weft adjustment device of rotary screen printing machine with simple structure, reliable operation and convenient maintenance

Embodiment 1

[0021] Such as figure 1 As shown, a weft adjusting device of a rotary screen printing machine comprises a weft adjusting roller 18 and a central shaft 17, the weft adjusting roller 18 is mounted on the central axis 17 through a ball bearing 16, and the weft adjusting roller 18 can be wound around the central axis 17 Rotate, a set of planetary gear transmission mechanism connected with the two ends of the central shaft 17 is installed on the cloth feeding box of the weft adjustment device of the rotary screen printing machine. The planetary gear transmission structure includes a gear stator 1, and the gear stator The inner ring of 1 is meshed with at least two planetary gears 4, and a planetary rod 6 is arranged between the planetary gears 4, and the planetary rod 6 and the planetary gears 4 are connected by a planetary gear shaft 7, and the planetary gear shaft 7 is connected to the planetary gear Planetary gear built-in bearings 8 are arranged between the gears 4, and the pla...

Embodiment 2

[0026] Such as figure 2 The cloth feeding box of the weft adjusting device shown is equipped with a gear transmission mechanism connected to the two ends of the central shaft 17, including an upper turntable 114 and a lower turntable 107, which are characterized in that: the upper turntable 114 and the lower turntable 107 There is a locking gear sleeve 106 on the outside. After the device is adjusted, the locking gear sleeve 106 will lock the upper turntable 114 and the lower turntable 107 tightly to prevent relative movement between the upper turntable 114 and the lower turntable 107, thereby preventing dangerous situations. , an oil cavity 110 is formed between the upper turntable 114 and the lower turntable 107, and the oil cavity 110 is filled with lubricating oil, which greatly reduces the friction force generated when the upper turntable 114 and the lower turntable 107 move relative to each other, so that the control More conveniently, the upper turntable 114 and the lo...

Abstract

The invention discloses a weft straightener of a circular screen printer. The weft straightener comprises a weft straightening roller and a center shaft, the weft straightening roller is mounted on the center shaft through a ball bearing, and the weft straightening roller can rotate around the center shaft. A cloth feeding box of the weft straightener of the circular screen printer is provided with a planetary gear drive mechanism in transmission connection with the two ends of the center shaft. The planetary gear drive mechanism comprises a gear stator, an inner ring of the gear stator is meshed with two or more planetary gears, planetary rods are arranged among the multiple planetary gears, the planetary rods and the planetary gears are connected through planetary gear shafts, planetary gear built-in bearings are arranged between the planetary gear shafts and the planetary gears, the planetary gear can conduct autoroatation around the planetary gear shafts, the other end of the center shaft is provided with a base, the center shaft penetrates through the base to be connected with a gear motor, and a center bearing is arranged between the base and the center shaft.

Description

Technical field: [0001] The invention relates to the technical field of textile machinery, in particular to a weft adjusting device of a rotary screen printing machine. Background technique: [0002] The rotary screen printing machine used in textile mills is a screen printing machine that uses a continuously rotating seamless cylindrical screen for printing. A rotary screen printing machine is usually composed of five parts: a cloth feeding device, a printing head, a drying device, a cloth falling device, and a weft adjusting device. There are many paths and a large space, of course, the price is also very expensive; in addition, there will be a certain degree of weft bending or weft skew before the fabric is set, so the weft skew must be corrected and sorted before the fabric is needled, so as to ensure The fabric achieves the best setting effect after high-temperature setting. The existing weft adjustment device usually adopts screw drive or chain drive. The transmission...
