Description
Technical Field
The invention relates to an embroidery machine, in particular to a take-up lever locking mechanism.
Background
As shown in figure 1, the tail end of the thread take-up B8 is provided with a roller which is embedded into a cam groove of the thread take-up cam 9, and the thread take-up cam 9 is fixedly connected with the main shaft and rotates along with the main shaft. When the color of the embroidery machine is changed, the main shaft rotates one circle continuously, and the thread take-up cam 9 also rotates one circle continuously so as to drive the thread take-up B8 to swing in a reciprocating manner. In the conventional thread take-up mechanism, the thread take-up A7 and the thread take-up B8 are locked, and the angle between the thread take-up A7 and the thread take-up B8 is a fixed value, so that the motion of the thread take-up B8 drives the motion of the thread take-up A7, and the thread take-up lever 1 can swing back and forth.
Since the main shaft does not cause the needle bar to move during the rotation, the thread take-up lever moves in one idle stroke and has no practical significance.
Disclosure of Invention
The invention aims to solve the technical problem of providing a take-up lever locking mechanism which avoids the idle stroke of the movement of the take-up lever.
In order to solve the technical problem, the invention adopts the following technical scheme: the take-up lever locking mechanism comprises a main shaft, a take-up cam, a take-up A, a take-up B and a take-up lever, wherein the take-up cam is installed on the main shaft and rotates along with the main shaft, the take-up B is driven by the take-up cam, the take-up A is driven by the take-up B and enables the take-up lever to act, the take-up A and the take-up B are rotatably nested on the take-up sleeve, the take-up sleeve is installed on a take-up pin, a torsion spring is installed on the take-up sleeve, the two ends of the torsion spring respectively buckle the take-up A and the take-up B and enable the take-up A and the take-up B to rotate towards the direction with the angle increasing, when the take-up cam drives the take-up B to swing upwards, the take-up B enables the take-up A to rotate upwards through the torsion spring, and the take-up A is provided with a take-up stop pin which enables the take-up A to rotate downwards when the take-up B rotates downwards.
Preferably, the thread take-up catch is tangent to a surface of the thread take-up B in a normal state so that the surface can act on the thread take-up catch and drive the thread take-up A to rotate downward.
Preferably, an electromagnet is further provided to block the upward movement of the take-up thread a when the color of the embroidery machine is changed.
Preferably, the tail end of the thread take-up B is provided with a roller, and the roller is embedded into a cam groove of the thread take-up cam.
The invention also provides an embroidery machine which is provided with the take-up lever locking mechanism.
According to the technical scheme, the take-up thread A and the take-up thread B can rotate with the take-up sleeve, the two ends of the torsion spring respectively buckle the take-up thread A and the take-up thread B, and the torsion force of the torsion spring enables the take-up thread A and the take-up thread B to rotate in the angle increasing direction, so that when the take-up cam drives the take-up thread B to swing upwards, the take-up thread A can rotate upwards through the torsion spring, and when the take-up thread B rotates downwards, the take-up thread B can rotate downwards through the take-up stop pin, and therefore the motion rules of the take-up thread A and the take-up thread B in a normal embroidery state are guaranteed.
When the embroidery machine changes colors, the take-up thread A and the take-up thread B are required to be at the lowest position, at the moment, the electromagnet is opened, and when the take-up thread A moves upwards, the take-up thread A is blocked by the extending end of the electromagnet, so that the take-up thread A is static, the take-up lever is kept static, and the take-up thread B continues to move.
Drawings
The invention is further described with reference to the following figures and detailed description:
FIG. 1 is a schematic structural view of a thread take-up mechanism;
fig. 2 is a schematic structural view of the thread take-up lever locking mechanism.
Detailed Description
Embodiment 1, as shown in fig. 1 and 2, a thread take-up lever locking mechanism includes a main shaft mounted on a handpiece housing, a thread take-up cam 9, a thread take-up A7, a thread take-up B8, and a thread take-up lever 1, wherein the thread take-up cam 9 is mounted on the main shaft and rotates with the main shaft, the thread take-up B8 is driven by the thread take-up cam 9, a roller is arranged at a tail end of the thread take-up B8, the roller is embedded into a cam groove of the thread take-up cam 9, and the thread take-up A7 is driven by the thread take-up B8 and drives the thread take-up lever 1 to operate.
The thread take-up A7 and the thread take-up B8 are not locked, and the thread take-up A7 and the thread take-up B8 are rotatably nested on the thread take-up sleeve 3, so that the thread take-up A7 and the thread take-up B8 can rotate with the thread take-up sleeve 3. The thread take-up sleeve 3 is arranged on the thread take-up pin 2, the torsion spring 4 is arranged on the thread take-up sleeve 3, the two ends of the torsion spring 4 respectively buckle the thread take-up A7 and the thread take-up B8, and the torsion force of the torsion spring 4 enables the thread take-up A7 and the thread take-up B8 to rotate towards the direction of increasing the angle.
Therefore, when the thread take-up cam 9 drives the thread take-up B8 to swing upwards, the thread take-up B8 rotates the thread take-up A7 upwards through the action of the torsion spring 4. The thread take-up stop pin 5 is fastened on the thread take-up A7, and the head end of the thread take-up stop pin 5 is exactly tangent to one surface of the thread take-up B8 in a normal state. Therefore, when the thread take-up B8 is rotated downward, the thread take-up B8 can rotate the thread take-up A7 downward by the thread take-up stopper pin 5, thereby ensuring the movement regularity of the thread take-up A7 and the thread take-up B8 in the normal embroidering state.
In addition, the thread take-up lever locking mechanism is also provided with an electromagnet 6 which blocks the upward movement of the thread take-up B8 when the color of the embroidery machine is changed. When the color of the embroidery machine is changed, the take-up thread A7 and the take-up thread B8 are required to be at the lowest position, at the time, the electromagnet 6 is opened, and when the take-up thread A7 moves upwards, the take-up thread A7 is blocked by the extending end of the electromagnet 6, so that the take-up thread A7 is static, the take-up rod 1 is kept static, and the take-up thread B8 continues to move.
Traditional structure, when trading the look, the needle bar does not lower the needle, and the take-up lever is once idle stroke, and this can cause the empty of upper thread to draw, because the take-up lever this round action upper thread is not consumed, then leads to the tension of next needle upper thread to tighten inadequately to influence high-end embroidery's quality. When a certain needle position is broken and needs to be subjected to embroidery supplementation, the existing machine moves the needle rod of the embroidery needle position, other needle position needle rods are static, but the thread take-up levers of all the needle positions move, so that idle strokes of the thread take-up levers of other needle positions are caused, the quality of next embroidery of all other needle positions is influenced, and especially the influence on high-end embroidery or embroidery with two far needle positions is more obvious. When the color of the embroidery machine is changed, the invention can keep the take-up lever still and the take-up B continues moving, thus solving the problems and having good effect of improving the quality of high-end embroidery.
