Description

Guide bar shogging resetting device of warp knitting machine

Technical Field

The utility model relates to a textile machinery equipment field especially relates to a tricot machine sley bar sideslip resetting means.

Background

The warp knitting machine mainly comprises a knitting mechanism, a guide bar shogging mechanism, a let-off mechanism, a drawing and coiling mechanism and a transmission mechanism. The guide bar shogging mechanism makes the guide bar shogging according to the requirement of the knitted fabric structure in the knitting process, and pads the warp yarns on the needles so as to knit the knitted fabric with a certain tissue structure.

Conventional tricot machine sideslip mechanism as disclosed in the utility model patent of chinese patent application No. 200820215729.3, it includes sley bar, connecting rod, slider, speed reducer, wire rope, pressure spring seat, pressure spring and pressure spring pole, has the connecting rod to link to each other between sley bar and the slider, and the one end of pressure spring pole is connected on the pressure spring in the pressure spring seat, and the other end passes through wire rope and links to each other with the sley bar. When the cam is rotated from the low position to the high position, the guide bar is pushed to the left side by the cam to move, the lower end of the compression spring rod also moves to the left, and the compression spring is in a compression state at the moment; when the cam is rotated to the low position from the high position, the pressure spring rod pressed by the pressure spring pulls the steel wire rope to move rightwards so as to drive the guide bar to move rightwards, and therefore the left and right transverse movement of the guide bar is realized through the continuous conversion of the high position and the low position of the cam. However, the transverse moving mechanism is only provided with a group of pressure springs, when the guide bar performs large needle moving or high-speed rotation, the conditions that the stroke is limited or the resonance frequency of the springs cannot be followed easily occur, so that the surface of the jacquard weaving cam and the bulb of the guide bar slide block cannot be stably and tightly matched.

Disclosure of Invention

An object of the utility model is to provide a modified tricot machine sley bar sideslip resetting means.

Realize the utility model discloses the technical scheme of purpose is: the utility model provides a modified tricot machine sley bar sideslip resetting means, it includes swing arm and guide bar, swing arm one end is articulated with the haulage rope that is used for the pulling sley bar, and fixed mounting has a spring bracket on the sley bar support of the top of the other end of swing arm, and spring bracket's top fixed mounting has first spring holder, the lower extreme and the swing arm universal connection of guide bar, in the upper end of guide bar penetrates spring bracket by spring bracket's bottom, the second spring holder is installed to the upper end of guide bar, the third spring holder is installed to the lower extreme side of guide bar, and the fourth spring holder is installed to spring bracket's bottom, install the spring between first spring holder and the second spring holder, between third spring holder and the fourth spring holder respectively.

Furthermore, at least one spring seat is installed in the middle of the guide rod, a spring is installed between every two adjacent spring seats, a long spring is decomposed into multiple sections of short springs, the short springs are more convenient to process, and the spring reset action is more stable when the needle is moved greatly.

Further, the guide rod is arranged perpendicular to the horizontal plane to prolong the service life of the spring.

The utility model discloses an add spring bracket, through the spring combination of the spring and guide bar and the spring bracket bottom at guide bar and spring bracket top, select to use different fixed frequency's spring to form reset spring group, utilize reset spring group to prescribe a limit to sley bar motion range, can break through the big needle shifting demand of the upper limit of tricot machine main shaft rotational speed in order to adapt to tricot machine lopping mechanism, improved work efficiency.

Drawings

Fig. 1 is a schematic structural view of a warp knitting machine guide bar shogging resetting device according to an embodiment of the present invention.

Detailed Description

The following description of the preferred embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in figure 1, a warp knitting machine guide bar shogging resetting device comprises a swing arm 1 and a guide rod 2, one end of the swing arm 1 is hinged to a traction rope 20 used for pulling a guide bar 10, a spring support 3 is fixedly mounted on a guide bar support 30 above the other end of the swing arm 1, a first spring seat 41 is fixedly mounted at the top 31 of the spring support 3, the lower end 21 of the guide rod 2 is in universal connection with the swing arm 1, the upper end 22 of the guide rod 2 penetrates into the spring support 3 from the bottom 32 of the spring support 3, a second spring seat 42 is mounted at the upper end 22 of the guide rod, a spring 51 is mounted between the first spring seat 41 and the second spring seat 42, a third spring seat 43 is mounted on one side of the lower end 21 of the guide rod 2, a fourth spring seat 44 is mounted at the bottom 32 of the spring support, a fifth spring seat 45 is mounted in the middle of the guide rod 2, and a third spring seat 43 and the, Springs (52, 53) are mounted between the fifth spring seat 45 and the fourth spring seat 44, respectively.

When the guide bar shogging mechanism is in operation, when the cam 40 of the guide bar shogging mechanism of the warp knitting machine is switched from a low position to a high position, the guide bar 10 is pushed to the left side by the cam 40 to move, the traction rope 20 pulls the swing arm 1 to move to the left so as to drive the lower end of the guide rod 2 to rotate clockwise along the center of the swing arm, and at the moment, the springs (51, 52 and 53) are in a compressed state; when the cam 30 is turned from the high position to the low position, the spring (51, 52, 53) rebounds to pull the guide rod 2 upwards, so as to drive the swing arm 1 to pull the traction rope 20 to move rightwards, and further realize the resetting of the guide bar 10. The utility model discloses constitute reset spring group in the spring that the upper end of guide bar 2 was add and the spring of guide bar pole body, can break through the big needle demand that moves of the upper limit of tricot machine main shaft rotational speed in order to adapt to tricot machine lopping mechanism, improved work efficiency.

The guide rod of the utility model can meet the work requirement only by being arranged longitudinally, but the arrangement vertical to the horizontal plane can prevent the spring from deforming, which is more beneficial to prolonging the service life of the spring; the number of the springs on the guide rod is not limited to that shown in the embodiment, and the springs can be increased or decreased according to actual production needs; the type of the spring is also selected according to actual production requirements.

The above only be the embodiment of the utility model discloses a not consequently restriction the patent scope of the utility model, all utilize the equivalent flow transform that the content of the specification was made, or direct or indirect application is in other relevant technical field, all including on the same reason the utility model discloses a patent protection within range.
