Description

Middle mountain drive mechanism in straight-bar machines
Technical field
The invention belongs to technical field of knitting machinery, particularly to the middle mountain drive mechanism in a kind of straight-bar machines.
Background technology
Middle mountain guide block and needle overturning guide block are all the core components in flat machine, and they belong to knitting mechanism, are arranged on motherboard, are in head, for controlling the Cam Track of knitting needle to complete the braid movement of series of complex.Move up and down in needing groove corresponding on motherboard continually due to the demand of braiding, middle mountain guide block and needle overturning guide block to switch between operating position and rest position, and middle mountain guide block and needle overturning guide block same time only one of which need in running order.Existing flat machine all uses the motion being controlled two kinds of guide blocks by the pushing means of solenoid actuated, and controlled two kinds of respective pushing meanss of guide block respectively by flat machine computer and cooperate, to ensure that a kind of guide block the most in need of same time is in operating position, the flat machine structure of this pattern is complicated, big to the computational load of computer, programming difficulty is high, coordinates error-prone, the energy that multiple pushing meanss consume is many, and production cost is higher.
Summary of the invention
The invention aims to solve the problems referred to above, it is provided that a kind of can effectively control in mountain guide block and needle overturning guide block crisscross motion straight-bar machines in middle mountain drive mechanism.
To this end, the middle mountain drive mechanism that the technical scheme is that in straight-bar machines, it is characterised in that: include connecting rod base, motor, middle Rhizoma Atractylodis Macrocephalae bar, guide block installing rack, middle mountain guide block and needle overturning guide block;Described motor is arranged on connecting rod base, and motor shaft is installed a cam;Being arranged in the first rotary shaft in the middle of described middle Rhizoma Atractylodis Macrocephalae bar, the first rotary shaft is fixedly mounted on connecting rod base, and middle Rhizoma Atractylodis Macrocephalae bar can rotate around the first rotary shaft;Described middle Rhizoma Atractylodis Macrocephalae bar one end is against on cam, and the other end is against at the tip of middle mountain guide block;Described middle mountain guide block and needle overturning guide block are installed on guide block installing rack, and at the tip of middle mountain guide block, the installing hole through guide block installing rack is inconsistent with middle Rhizoma Atractylodis Macrocephalae bar;Being provided with spring at the tip of described needle overturning guide block, spring one end is against at the tip of needle overturning guide block, and the other end is against on guide block installing rack;Having a lever between described middle mountain guide block and needle overturning guide block, lever rotation is arranged in the second rotary shaft, and the second rotary shaft is fixed on guide block installing rack;Described middle mountain guide block and needle overturning guide block are equipped with groove towards the side of lever, and lever two ends are respectively placed in the groove of middle mountain guide block and needle overturning guide block.
When the present invention works, driven by motor cam rotation, on projection outline, each point is different to the distance of motor shaft, when the convex place of cam rotation to outline, can be to power upwards of middle Rhizoma Atractylodis Macrocephalae bar right-hand member (one end inconsistent with cam), make middle Rhizoma Atractylodis Macrocephalae bar left end push down on middle mountain guide block so that middle mountain guide block is released downwards, enter duty;Meanwhile, middle mountain guide block drives one end of lever to move down, then the lever other end drives and moves on needle overturning guide block, state of deactivating.When the recess of cam rotation outline, the spring at needle overturning guide block tip is to one downward power of needle overturning guide block so that needle overturning guide block is released downwards, enters duty, moves, state of deactivating simultaneously in lever drives on the guide block of mountain.The present invention utilize cam to control in conjunction with lever principle in the elevating movement of mountain guide block, it is achieved the work switching of middle mountain guide block and needle overturning guide block, Ensure that a kind of guide block the most in need of same time is in operating position, meet braiding demand.
Accompanying drawing explanation
It is described in further detail below in conjunction with accompanying drawing and embodiments of the present invention
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the side sectional view of the present invention.
Figure is labeled as: connecting rod base 1, motor 2, middle Rhizoma Atractylodis Macrocephalae bar 3, pole 31, guide block installing rack 4, middle mountain guide block 5, needle overturning guide block 6, cam the 7, first rotary shaft 8, bearing 9, spring 10, lever the 11, second rotary shaft 12.
Detailed description of the invention
See accompanying drawing.The present embodiment includes connecting rod base 1, motor 2, middle Rhizoma Atractylodis Macrocephalae bar 3, guide block installing rack 4, middle mountain guide block 5 and needle overturning guide block 6;Described motor 2 is arranged on connecting rod base 4, and motor shaft is installed a cam 7;Being arranged in the first rotary shaft 8 in the middle of described middle Rhizoma Atractylodis Macrocephalae bar 3, the first rotary shaft 8 is fixedly mounted on connecting rod base 1, and middle Rhizoma Atractylodis Macrocephalae bar 3 can rotate around the first rotary shaft 8;Installing a bearing 9 at the right-hand member of described middle Rhizoma Atractylodis Macrocephalae bar 3, bearing is against on cam 7, and bearing rotates along the outline of cam, and along with on outline, each point is different to axle center distance, middle Rhizoma Atractylodis Macrocephalae bar 3 rotates around the first rotary shaft 8;Installing a pole 31 at the left end of described middle Rhizoma Atractylodis Macrocephalae bar 3, pole 31 is against at the tip of middle mountain guide block 5;Described middle mountain guide block 5 and needle overturning guide block 6 are installed on guide block installing rack 4, pass the installing hole of guide block installing rack 4 at the tip of middle mountain guide block 5, inconsistent with the pole 31 of middle Rhizoma Atractylodis Macrocephalae bar;Being provided with spring 10 at the tip of described needle overturning guide block 6, spring 10 one end is against at the tip of needle overturning guide block 6, and the other end is against on guide block installing rack 4;Having a lever 11 between described middle mountain guide block 5 and needle overturning guide block 6, lever 11 is rotatably installed in the second rotary shaft 12, and the second rotary shaft 12 is fixed on guide block installing rack 4;Described middle mountain guide block 5 and needle overturning guide block 6 are equipped with groove towards the side of lever 11, lever 11 two ends are respectively placed in the groove of middle mountain guide block 5 and needle overturning guide block 6, lever makes the middle mountain guide block 5 at two ends and needle overturning guide block 6 be that only one of which is in operating position one on the other forever.
During the present embodiment work, motor 2 band moving cam 7 rotates, when cam 7 turns to the convex place of outline, can be to power upwards of right-hand member (one end inconsistent with cam) of middle Rhizoma Atractylodis Macrocephalae bar 3, the pole 31 making middle Rhizoma Atractylodis Macrocephalae bar 3 left end pushes down on middle mountain guide block 5, middle mountain guide block 5 is released downwards, enters duty;Meanwhile, middle mountain guide block 5 drives one end of lever 11 to move down, then lever 11 other end drives and moves on needle overturning guide block 6, state of deactivating, and now the convex place of cam 7 makes the spring 10 at needle overturning guide block tip be in compressive state to the power with middle Rhizoma Atractylodis Macrocephalae bar 3.When cam 7 rotates the recess of outline, 6 one downward power of needle overturning guide block given by the spring 10 of compression at needle overturning guide block tip so that needle overturning guide block 6 is released downwards, enter duty, move, state of deactivating simultaneously on lever 11 band disorder of internal organs mountain guide block 5.
