Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

referring to fig. 1 and 2, for the utility model discloses a telescopic reed, including base 1, base 1's bottom is equipped with the elevating gear 14 that drives base 1 and reciprocate, is equipped with telescopic machanism 13 on base 1, and telescopic machanism 13 sets up on base 1, is equipped with on the expansion bracket 11 and supplies reed 100 fixed mounting's sley 12, is equipped with the adjusting nut 33 of adjusting the reed 100 elasticity on the sley 12. The lifting device 14 comprises a support frame 16 fixedly connected with the base 1 and a lifting component 17 driving the support frame 16 to move up and down.

Referring to fig. 2 and 3, the lifting assembly 17 includes a fixing base 15, a lifting motor 18 fixed on the fixing base 15, and a linkage screw 19 rotatably connected to a rotating shaft of the lifting motor 18, a support 2 for the linkage screw 19 to rotate is provided on the fixing base 15, a worm wheel 21 engaged with the teeth of the linkage screw 19 is provided on the support 2, a threaded rod 22 is provided on the inner diameter of the worm wheel 21, and the top of the threaded rod 22 is fixedly connected to the support frame 16. When the lifting motor 18 drives the linkage screw 19 to rotate, the worm wheel 21 is engaged by the linkage screw 19 to rotate, and the worm wheel 21 is rotatably arranged between the two rotating shafts, so that when the worm wheel 21 rotates along with the linkage screw 19, the threaded rod 22 in the worm wheel 21 moves up and down in the length direction of the threaded rod 22. The top of the threaded rod 22 is fixed on the support frame 16, and the base 1 moves up and down.

Referring to fig. 3 and 4, the base 1 includes an upper sliding seat 23 and a lower rotating seat 24, a rotating lead screw 28 is disposed in the lower rotating seat 24, a telescopic motor 29 rotatably connected to the rotating lead screw 28 is disposed outside the base 1, and a rotating shaft of the telescopic motor 29 is connected to the rotating lead screw 28. The rotary screw 28 is provided with a slide block 27, and after the telescopic motor 29 rotates, the rotary screw 28 linearly moves back and forth in the lower rotary seat 24. Be equipped with fixed first telescopic shaft 25 on the expansion bracket 11, first telescopic shaft 25 rotates with the slider 27 of bottom to be connected, therefore slider 27 will drive first telescopic shaft 25 and remove at the in-process that removes, accomplishes the flexible function of expansion bracket 11. A second telescopic shaft 26 (refer to fig. 2) is disposed on one side of the telescopic frame 11 away from the first telescopic shaft 25, and the slider 27 drives the telescopic frame 11 to move between the first telescopic shaft 25 and the second telescopic shaft 26.

Referring to fig. 3 and 4, a plurality of telescopic shafts 3 are arranged on the telescopic frame 11 between the first telescopic shaft 25 and the second telescopic shaft 26, a sliding chute 36 for the telescopic shafts 3 to move is arranged at the top of the upper sliding seat 23, and a sliding shaft 31 is arranged at the bottom of the telescopic shafts 3 in the upper sliding seat 23; during the process of moving the telescopic frame 11 by the slide block 27, the slide shaft 31 rotates in the upper slide seat 23. Thereby increasing the slidability of the entire telescopic frame 11. Secondly, the sliding shaft 31 can increase the toughness of the whole telescopic frame 11 in the length direction, and reduce the phenomenon that the telescopic frame 11 shakes because the bottoms of the telescopic shafts 3 are not fixed when the telescopic frame 11 works.

Referring to fig. 5, the side wall of the base 1 is provided with a scale 32, the scale 32 is used for measuring the moving distance of the telescopic frame 11, when the telescopic frame 11 slides in the sliding groove 36, the reed 100 on the sley 12 will deviate by a certain angle, and then the density of the needles on the whole reed 100 is changed, so that the density of the threads between the needles is changed. Therefore, the contraction distance of the whole telescopic frame 11 has a great relation, and the density of the silk threads can be better controlled by using the graduated scale 32. The bottom of base 1 is equipped with the spirit level 37 of fixing in base 1 bottom, and spirit level 37 is used for detecting whether base 1 is horizontal, because base 1 can be in the different removal of direction of height, if base 1 is not in the position that the level is parallel, causes the drop of silk thread very easily. The bottom of the supporting frame 16 is provided with a fixing nut 34 for adjusting the horizontal height of the base 1. The fixed seat 15 is provided with a controller 35 for controlling the lifting speed of the lifting motor 18.

The implementation principle of the embodiment is as follows: according to the needs of the density of the silk threads, the length of the telescopic frame 11 on the base 1 is adjusted by the telescopic motor 29, so that the angle of the sley 12 is deviated, and the density of the stitches on the row in the whole reed 100 is further changed. After the silk threads are sequentially installed on the reed 100, the lifting motor 18 is started, the lifting motor 18 drives the linkage screw rod 19 to rotate, the linkage screw rod 19 drives the worm wheel 21 to rotate, the two ends of the worm wheel 21 are connected with the rotating shaft, so that the threaded rod 22 in the worm wheel 21 moves upwards or downwards when the worm wheel 21 rotates, and the threaded rod 22 moves up and down to drive the base 1 to move up and down due to the fact that the top of the threaded rod 22 is fixedly connected with the supporting seat. In the process that the silk thread base 1 moves up and down, the silk thread moves up and down on the pin header of the reed 100, and then the silk thread is reduced and transmitted at the same position on the pin header, so that the pin header is abraded.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
