Abstract
The utility model discloses an anti -reverse -rotation device for spinning machine, it includes frame, main shaft, ratchet, antifriction bearing, cam, ejector pin and spring, the main shaft alternates through the frame, and both connect through a pair of antifriction bearing, the main shaft alternates through outwardly directed one section frame, installs the cam in the extension section here, the cam cooperation has the ejector pin, the ejector pin passes through the mounting hole and installs in the frame, ejector pin one side sets up and articulates with a spring, the spring other end is installed in the frame, ratchet's ratchet is fixed on the main shaft, and the matched with pawl is fixed in the frame, the utility model has the advantages of, main shaft rotational stabilization can reverse by quick effectual prevention main shaft to avoid broken needle, broken string phenomenon, improved work efficiency.
Description
Technical field:
The utility model relates to technical field of textile machine, specifically relates to a kind of anti-reverse-rotation device for textile machine.
Background technology:
The suturing mechanism of textile machine utilize the rotation of cam make with it near push rod carry out the action that presets, to complete the demand of sewing, because the rising amount of cam is comparatively large, in order to ensure the close contact of push rod and cam, push rod needs hitch spring, and spring must have enough elastic force.But; elastic force increases; the reaction force of push rod to cam is also increased; because main shaft is can Double-directional rotary; when cam rotates close to peak, if just shut down, the reaction force of push rod likely makes cam and main shaft reversion; cause the impact of broken needle, broken string, this can bring inconvenience to user.
At main shaft extension stationary cam and unilateral bearing in existing technology, wherein reached the effect stoping main shaft to reverse by unilateral bearing, this design has following problem:
1, because cam and unilateral bearing are all in main shaft extension, main shaft can be caused axially to have certain distortion, cause operating accuracy to reduce.
2, unilateral bearing is just unsettled is alone arranged on main shaft extension, and unilateral bearing does not play the effect preventing main shaft from reversing in fact, and the reaction of unilateral bearing anti-reverse is relatively slow, can not main shaft be avoided completely to reverse.
Utility model content:
The purpose of this utility model is not enough for prior art, provides a kind of anti-reverse-rotation device for textile machine that can main shaft be stoped fast and effectively to reverse.
For achieving the above object, the utility model provides a kind of anti-reverse-rotation device for textile machine, and it comprises frame, main shaft, ratchet mechanism, rolling bearing, cam, push rod and spring; Main shaft is inserted through frame, and both are connected by a pair rolling bearing; Main shaft is inserted through frame and protruding one section, and this extension is provided with cam; Described cam engagement has push rod, and described push rod is arranged in frame by installing hole; Described push rod side arranges and mounts with a spring, and the described spring other end is arranged in frame; The ratchet of ratchet mechanism is fixed on main shaft, and the ratchet matched is fixed in frame;
Preferred as technique scheme, described ratchet mechanism has two.
The beneficial effects of the utility model are: due to the existence of a pair rolling bearing, and main axis is stablized; And in main shaft extension, only having cam, cam near frame, decreases the axial deformation of main shaft as far as possible; Due to the existence of a pair ratchet mechanism, can main shaft be stoped fast and effectively to reverse, thus avoid broken needle, broken string phenomenon, increase work efficiency.
Accompanying drawing illustrates:
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:

Fig. 3 is the part sectioned view of frame of the present utility model, rolling bearing, ratchet mechanism installation site;
Fig. 4 is the installation site schematic diagram of frame of the present utility model and ratchet mechanism.
In figure, 10, frame; 20, main shaft; 30, ratchet mechanism; 31, ratchet; 32, ratchet; 40, cam; 50, push rod; 60, spring; 70, rolling bearing.
Detailed description of the invention:
Below in conjunction with accompanying drawing, following describing in detail is done to the utility model.For sake of convenience, following " on ", D score, "left", "right" be consistent with the direction, upper and lower, left and right of accompanying drawing itself.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of anti-reverse-rotation device for textile machine, it comprises frame 10, main shaft 20, ratchet mechanism 30, rolling bearing 70, cam 40, push rod 50 and spring 60; Main shaft 20 is inserted through frame 10, and both are connected by a pair rolling bearing 70; Main shaft 20 is inserted through frame 10 and protruding one section, and this extension is provided with cam 40; Described cam 40 is combined with push rod 50, and described push rod 50 is arranged in frame 10 by installing hole; Described push rod 50 side arranges and mounts with a spring 60, and described spring 60 other end is arranged in frame 10; The ratchet 31 of ratchet mechanism 30 is fixed on main shaft 20, and the ratchet 32 matched is fixed in frame 10.
Described ratchet mechanism 30 has two.
When the utility model is used for the anti-reverse-rotation device work of textile machine, main shaft 20 is with moving cam 40 to do continuous movement at the uniform velocity, cam 40 drive with it near push rod 50 carry out the action that presets, to complete the demand of sewing.Just shut down when the peak of cam 40 side contacts with push rod 50; because spring 60 can make cam 40 reverse; when main shaft 20 has reverse trend; ratchet mechanism 30 works; locked main shaft 20; stop and reverse the broken needle caused, impact of breaking by main shaft 20, make the performance of machinery more reliable and more stable.Due to the existence of a pair rolling bearing 70, make main shaft 20 slow-roll stabilization; And in main shaft 20 extension, only having cam 40, cam 40 near frame 10, decreases the axial deformation of main shaft 20 as far as possible; Due to the existence of a pair ratchet mechanism 30, main shaft 20 can be stoped fast and effectively to reverse, thus avoid broken needle, broken string phenomenon, increase work efficiency.
The foregoing is only preferred embodiment of the present utility model, therefore do not limit protection domain of the present utility model, every equalization change done according to the utility model all belongs in protection domain that the utility model contains with modifying.
