Example one
Referring to fig. 1 and 2, the embodiment provides a thread pressing device of a flat knitting machine, which is mounted on a carriage of the flat knitting machine and comprises a bracket 1, a brush holder 4 and a brush 5, wherein the bracket 1 is fixed on the carriage; the brush 5 is fixed on the brush seat 4 through a brush clamp, and the brush 5 is a replaceable component, so that the cost is reduced; the brush holder 4 can be connected on support 1 relative to what support 1 removed, install the executive component that can drive the brush holder and reciprocate on support 1, when the flat-bed machine hook need collude the line, the executive component drives brush holder 4 and moves down, and brush 5 depresses the yarn this moment, and when the flat-bed machine hook need not collude the line, the executive component drives brush holder 4 and moves up, and brush 5 resets this moment. The utility model controls the brush 5 to move up and down according to the knitting requirements by additionally arranging the thread pressing device on the flat knitting machine triangular seat carriage, and when the needle hook needs to hook the thread, the executing part drives the brush 5 to move down to press the thread down, thereby ensuring that the knitting needle can hook the thread smoothly; when the hook does not need to hook the thread, the executive component resets to drive the hairbrush 5 to withdraw from the working position, so that the thread pressing action is matched to meet the requirement that the knitting needle hooks the yarn, the stability of the thread hooking is improved, and the production efficiency is improved. The embodiment adopts the brush to press down, can prevent to press down or move the in-process and tear yarn apart, also can adopt the lower briquetting structure of other soft materials.
In this embodiment, the actuating member is a cylinder 2, the cylinder 2 is fixed on the bracket 1 through a nut, and a piston rod of the cylinder 2 is fixedly connected with the brush holder 4. The installation positions of the air cylinder 2 and the support 1 are adjustable, and the pressing amount of the yarn can be adjusted by adjusting the installation positions of the air cylinder 2 and the support 1. The type of the cylinder 2 in the embodiment can be selected according to the requirements of customers.
In this embodiment, a guiding mechanism for moving the brush holder 4 up and down is disposed between the brush holder 4 and the bracket 1, and the brush 5 is stabilized by the guiding mechanism to move up and down. Specifically, the guide mechanism comprises a waist hole 11 arranged on the support 1 and a screw 6 penetrating through the waist hole 11 and capable of moving along the waist hole, and the brush seat 4 is movably connected with the support 1 relatively through the matching of the screw 6 and the waist hole 11. The up-and-down movement of the brush base 4 is stabilized by the up-and-down movement of the screw 6 along the waist hole 11, and the reliability of the operation is improved.
The brush holder 4 is a clamping device fixedly assembled by two plates, an opening for clamping and fixing the brush clamp is arranged below the two plates, a connecting block fixed with a piston rod of the cylinder 2 is fixed on one plate, and a through hole through which a screw 6 penetrates is arranged on the other plate.
The utility model discloses a support 1 is established on the reciprocating sliding in the triangular seat balladeur train of flat-bed machine needle bed, moves back and forth along with the triangular seat balladeur train, when the knitting needle gets into weaving the region, according to weaving needs, controls brush 5 and moves from top to bottom, when the hook of a needle needs to collude the line, pushes down brush 5 through cylinder 2 and presses down the yarn, ensures that the knitting needle colludes the yarn smoothly; when the hook does not need to hook the thread, the cylinder 2 is reset to drive the brush 5 to exit from the working position. And the required pressing amount of the yarn can be controlled by adjusting the mounting position of the air cylinder 2 on the bracket 1.
Example two
The difference between the present embodiment and the first embodiment is: the executive component is an electromagnet, the electromagnet is fixed on the support 1, the electromagnet is connected with the brush base 4 in an adsorption mode, when the electromagnet is powered on, the brush base 4 moves upwards under the action of the electromagnet to reset, and when the electromagnet is powered off, the brush base 4 moves downwards under the self weight or an elastic structure. When a knitting needle enters a knitting area, the brush 5 is controlled to move up and down according to knitting requirements, when a hook needs to hook a yarn, the electromagnet is powered off, the brush seat 4 moves down to drive the brush 5 to move down to press the yarn down, and the knitting needle is ensured to hook the yarn smoothly; when the hook does not need to hook the thread, the electromagnet is electrified, the electromagnet absorbs the fluffing brush seat 4, and the electromagnet resets to drive the brush 5 to exit from the working position. And the required pressing amount of the yarn can be controlled by adjusting the installation position of the electromagnet on the bracket 1. Of course, the moving downwards can be driven by the striking force generated by the electromagnet, and the resetting can be carried out under the driving of the elastic structure.
The rest of the structure and the functions can be referred to the first embodiment.
