Description
Technical Field
The utility model relates to a presser foot actuating mechanism for embroidery machine.
Background
The computerized embroidery machine is increasingly wide in daily application due to high speed, intellectualization and diversification of the embroidery process, and the requirement on the embroidery machine is higher and higher.
In the working process of the existing embroidery machine, a motor drives a main shaft, and the main shaft drives a needle rod to move up and down through a transmission mechanism to realize embroidery. In the structure of the traditional embroidery machine, as shown in figure 1, a presser foot 1 is directly sleeved on a needle rod 2, an upper dead point, a lower dead point 3 and a presser foot spring 4 are arranged above the presser foot 1, the presser foot spring 4 is propped against the presser foot 1, when the structure works, the needle rod 2 drives the dead point to move up and down, the dead point compresses the spring 4, the presser foot 1 is indirectly compressed, and the presser foot 1 compresses cloth. The presser foot is used for feeding cloth, and when the needle is pricked downwards, the cloth is not disturbed, so that the needle is pricked downwards smoothly. When the needle rises, the cloth is pressed to enable the needle to rise smoothly and bring out the thread. Without the presser foot, there is no perfect stitch.
As the rotating speed of the embroidery machine is faster and faster, the impact force of the presser foot 1 on the fabric is very large by the presser foot spring 4, and the quality of embroidery is affected. When the needle bar moves upwards and resets in the running state of the machine, the presser foot 1 immediately moves upwards and resets along with the needle bar 2 under the action of the presser foot spring 4, and the presser foot 1 cannot effectively press the fabric when the needle bar 2 resets, so that the fabric can be displaced under the action of the needle bar, and the quality of embroidery is affected.
In addition, since the pressure of the presser foot 1 depends on the pressure of the presser foot spring 4, the pressure of each spring cannot be ensured to be the same, which cannot ensure ideal cloth pressing effect of each presser foot 1. The upper stroke dead point, the lower stroke dead point and the up-and-down moving stroke of the presser foot 1 all depend on the needle bar, can not be independently adjusted, are difficult to adapt to different pressing requirements of fabrics with different thicknesses, and have poor universality; no embroidery machine capable of meeting the requirements is available in the market; therefore, the applicant provides a further improvement on the basis of the above to design a presser foot driving mechanism for an embroidery machine so as to meet the requirements of the existing market.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome current defect, provide a presser foot actuating mechanism for embroidery machine, the effectual surface fabric that compresses tightly to avoid the aversion of surface fabric, guaranteed the embroidery quality.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a presser foot actuating mechanism for embroidery machine which characterized in that: the device comprises a presser foot driver in transmission connection with the presser foot, and the presser foot driver inputs power through a transmission assembly, so that the presser foot driver moves up and down to drive the presser foot to move up and down repeatedly.
The utility model is further optimized, the presser foot driver comprises a presser foot driving block, a driver bracket, a pin rod, a guide rod and a built-in spring;
the driver bracket is fixedly arranged on the driving shaft; the presser foot driving block is movably arranged in the driver bracket through a pin rod, and a built-in spring is arranged between the presser foot driving block and the driver bracket;
the guide rod is fixed on the presser foot driving block through a screw.
It is further preferred to the utility model discloses, the driver support is the trilateral driver support that surrounds of integrated into one piece, and middle part vacuole formation is used for installing between the driver.
To the utility model discloses do further preferred, form the bayonet socket on the presser foot drive block, this bayonet socket is connected with the presser foot transmission through the presser foot transmission piece that the card was gone into.
To the utility model discloses do further preferred, the bayonet socket with there is 0.5 mm's clearance between the presser foot driving block.
The utility model is further optimized, and the compression amplitude of the built-in spring is between 0 and 2 mm.
It is right to do further preferred the utility model discloses, drive assembly includes the presser foot cam, the presser foot cam drives the three-eye connecting rod, the three-eye connecting rod passes through the connecting rod and drives the presser foot driver.
Compared with the prior art, the utility model discloses the beneficial effect who reaches is:
this patent technique provides a presser foot driver, makes the presser foot can be applicable to the surface fabric of different thickness, and the presser foot is within controllable range to the pressure of cloth. In order to achieve the technical purpose, the pressure foot driving mechanism for the embroidery machine provided by the patent technology is different from a conventional driver, and the pressure foot driver consists of a pressure foot driving block, a driver bracket, a pin rod, a guide rod and an internal spring. In order to ensure that the presser foot presses cloth fully, a spring is arranged in a presser foot driver to push a presser foot transmission block to drive the presser foot.
The working principle is as follows: the presser foot cam drives the three-eye connecting rod, the three-eye connecting rod drives the presser foot driver through the connecting rod, the presser foot driver drives the transmission block on the presser foot to drive the presser foot to reciprocate, and the presser foot transmission block is blocked into the presser foot driver and is vertically limited by the presser foot driver, and the presser foot cam is always followed to make reciprocating motion. When the needle rod moves upwards and resets, the presser foot moves upwards and resets along with the needle rod immediately under the action of the presser foot cam, and as the built-in spring is arranged on the presser foot drive, the compression amplitude of the built-in spring is between 0 and 2mm, namely the height amplitude of the presser foot during cloth pressing can be adjusted by 2mm at most, so that the presser foot effectively compresses the fabric when the presser foot cam resets in a small amplitude, thereby avoiding the displacement of the fabric and ensuring the quality of embroidery.
When the needle bar is lifted to a certain time, the compression force of the built-in spring is smaller than the lifting force of the presser foot cam, the presser foot of the belt wheel can be lifted upwards, the cloth pressing effect caused by uneven thickness of the fabric is solved, and the universality is greatly improved. In addition, a gap of 0.5mm is reserved between the presser foot driver and the presser foot transmission block, and the upper surface of the presser foot driver adopts a fillet design, so that the presser foot transmission block can be smoothly clamped into the presser foot driver when color changing is convenient, and the lower plane of the presser foot transmission block is ensured to be tightly attached to the lower plane of the presser foot driver.
According to the above, the utility model discloses can solve the weak point that exists among the prior art, the effectual surface fabric that compresses tightly to avoid the aversion of surface fabric, guaranteed the embroidery quality.
