Description

Box moves about opening

Technical Field

The utility model relates to the technical field of textile machinery, in particular to a box with an opening capable of moving left and right.

Background

The cross twisting and weaving of the weaving machine are realized by driving the shedding heald frame to move left and right through the driving part, in the prior art, the return of the shedding heald frame during the left and right movement is mainly realized by a spring, but the return of the spring has the defect of poor stability, so that the control precision of the weaving machine on the heald frame is difficult to improve.

Based on this, the present disclosure is thus directed.

SUMMERY OF THE UTILITY MODEL

Furthermore, the stop block is provided with a mounting groove opposite to the cam, and a roller is arranged in the mounting groove.

Furthermore, the input assembly comprises a driving shaft and a driven shaft which are rotatably connected to the box body, a driving gear is fixed on the driving shaft, a first driven gear and a second driven gear meshed with the driving gear are fixed on the driven shaft, and a transmission gear meshed with the first driven gear is arranged on the first transmission shaft.

The utility model has the advantages that:

1. the rotation of the cam drives the front and rear moving rods to move back and forth, and the front and rear moving rods are converted into left and right moving through the matching of the bevel gears and the sector gears, so that the device has the advantages of good stability and high precision;

2. the left and right moving rods and the front and rear moving rods are connected to the box body through linear bearings, so that the movement stability of the moving rods is further improved;

3. the input assembly adopts a plurality of gears to carry out power input, and the change of the translation frequency of the movable rod can be realized by setting different transmission ratios.

description of the reference symbols

The device comprises a box body 1, a first transmission shaft 2, a second transmission shaft 3, a third transmission shaft 4, a cam 5, a front and rear moving rod 6, a left and right moving rod 7, a stop block 8, a first rack 9, a second rack 10, a first bevel gear 11, a second bevel gear 12, a first sector gear 13, a second sector gear 14, a roller 15, a driving gear 16, a first driven gear 17, a second driven gear 18 and a transmission gear 19.

Detailed Description

The present invention will be described in further detail with reference to examples.

The present embodiment provides a box with a left-right opening, as shown in fig. 1 to 3, which includes a box body 1, and a driving shaft, a driven shaft, a first transmission shaft 2, a second transmission shaft 3, and a third transmission shaft 4 are rotatably connected to the box body 1. The driving shaft is fixed with a driving gear 16, the driven shaft is fixed with a driven gear 17 and a driven gear 18 engaged with the driving gear 16, and the driving shaft 2 is provided with a cam 5 and a transmission gear 19 engaged with the driven gear 17.

The box body 1 is provided with a front and rear moving rod 6 and a left and right moving rod 7 through linear bearings, the front and rear moving rod 6 is positioned at two sides of the cam 5 and is fixed with a stop block 8, and when the box body operates, the far end of the cam 5 can push the stop block 8 to realize the front and rear movement of the front and rear moving rod 6. One end of the front and rear moving rod 6 is provided with a first rack 9, the second transmission shaft 3 is provided with a first bevel gear 11 and a first sector gear 13 meshed with the first rack 9, the third transmission shaft 4 is provided with a second sector gear 14 and a second bevel gear 12 meshed with the first bevel gear 11, and the left and right moving rods 7 are provided with a second rack 10 meshed with the second sector gear 14.

Wherein, the dog 8 is provided with a mounting groove opposite to the cam 5, and the mounting groove is internally provided with a roller 15. Through setting up gyro wheel 15 for the contact between cam 5 and the dog 8 can be converted into rolling friction by sliding friction, has reduced the frictional force between cam 5 and the dog 8, has improved the smoothness nature of front and back travel bar 6 motion.

The transmission route of the device of the embodiment is as follows: the external driving equipment inputs power through a driving shaft, the power is transmitted to the transmission shaft I2 after passing through the driving gear 16, the driven gear II 18, the driven shaft, the driven gear I17 and the transmission gear 19 in sequence, the transmission shaft I2 drives the cam 5 to rotate, and the front and rear moving rods 6 move back and forth through the cooperation of the cam 5 and the two stop blocks 8. The movement of the front and rear moving rod 6 drives the first gear to move forward and backward, so that power is transmitted to the first sector gear 13, the first sector gear 13 drives the second transmission shaft 3 to rotate back and forth, then the power is transmitted to the second sector gear 14 after passing through the second transmission shaft 3, the first bevel gear 11, the second bevel gear 12 and the third transmission shaft 4 in sequence, and the left and right swinging of the second sector gear 14 drives the second rack 10 matched with the second sector gear to move left and right, so that the left and right moving rod 7 moves left and right.

The above embodiments are only used for explaining the concept of the utility model, and not for limiting the protection of the utility model, and any insubstantial modifications of the utility model using this concept shall fall within the scope of the utility model.
