In this embodiment, the airbag body 608 and the protrusion 609 are integrally formed, so that the integrally formed structure has higher strength, and is stronger and more durable. The balloon body 608 and the inside of the boss 609 are each filled with gas, and the balloon body 608 and the inner cavity of the boss 609 communicate with each other. When the airbag body 608 is in a free state, the side surfaces of the airbag body abut against two side walls of the oil storage cavity 601, meanwhile, the protruding portion 609 is located inside the through hole 605, on one hand, the airbag 604 can be effectively prevented from being displaced in the oil storage cavity 601 along the horizontal direction through the matching installation of the protruding portion 609 and the through hole 605, on the other hand, the protruding portion 609 can effectively plug the through hole 605, and external foreign matters are prevented from entering the oil storage cavity 601 from the through hole 605.
In some embodiments, referring to FIG. 3, the wall thickness of the boss 609 is less than the wall thickness of the balloon body 608. In this embodiment, since the wall thickness of the protruding portion 609 is smaller than the wall thickness of the airbag body 608, the deformation resistance of the protruding portion 609 is smaller than the deformation resistance of the airbag body 608, and the pressing plate 607 only needs to apply a small acting force to the airbag body 608 to elastically deform the protruding portion 609, so that the protruding portion 609 is enlarged in volume and moves to a side close to the oil absorbing piece 5, and finally, the acting force towards the center of the oil applying hole 501 is applied to the oil absorbing piece 5, so that the aperture of the oil outlet 603 and the aperture 605 which are displaced correspondingly is reduced.
In some embodiments, referring to FIG. 5, balloon body 608 is a ring-shaped member and protrusions 609 are uniformly arranged along the circumference of balloon body 608. In this embodiment, the airbag body 608 and the oil suction member 5 are coaxially disposed. The number of the projections 609 is plural, and is uniformly arranged in the circumferential direction of the balloon body 608. The number of through holes 605 is kept the same as the number of bosses 609. The pressing plate 607 applies an acting force to the airbag body 608, and at the same time, the plurality of protrusions 609 elastically deform, so that the acting force is applied to the oil absorbing member 5 along the circumference of the oil absorbing member 5, and the deformation of the oil absorbing member 5 along the circumferential direction is more uniform.
In some embodiments, referring to fig. 3 and 4, the pressure plate 607 is slidably engaged with the inner wall of the oil chamber 601 to divide the oil chamber 601 into an upper chamber 610 and a lower chamber 611. In this embodiment, the pressure plate 607 has the same size as the cross-section of the reservoir 601. The pressing plate 607 is annular and is in sliding fit with two side walls of the oil storage chamber 601, the lifting rod 606 is connected with the pressing plate 607 by welding, and the top end of the lifting rod 606 penetrates through the top of the oil storage box 6 and extends to the outside of the oil storage box 6. The number of the lifting rods 606 is at least two, and the lifting rods are uniformly arranged along the circumferential direction of the pressing plate 607, so that the acting force exerted by the lifting rods 606 on the pressing plate 607 is more balanced. The pressure plate 607 divides the inner cavity of the reservoir 6 into two relatively independent upper and lower chambers 610, 611, thereby separating the cooling oil from the bladder 604. The upper chamber 610 is the reservoir 601. When the sewing needle 2 moves downwards, the driving piece 101 applies a downward acting force to the lifting rod 606, the pressing plate 607 applies a downward acting force to the airbag body 608, the volume of the upper cavity 610 becomes large (due to the increase of the pressure of the upper cavity 610, cooling oil in the oil absorbing piece 5 can be absorbed into the upper cavity 610, so that the content of the cooling oil in the oil absorbing piece 5 is ensured to be at a normal level, and the waste of the cooling oil is reduced), the volume of the lower cavity 611 becomes small, the protruding part 609 applies an acting force towards the center of the oil coating hole 501 to the oil absorbing piece 5 close to the through hole 605, and the aperture of the oil absorbing piece 5 close to the through hole 605 is reduced; when the sewing needle 2 moves upwards, the action of the driving member 101 on the lifting rod 606 disappears, the air bag body 608 exerts an upward acting force on the pressing plate 607 under the action of the self elastic force, the volume of the lower cavity 611 is increased, and the volume of the upper cavity 610 is decreased, so that the cooling oil in the upper cavity 610 is pushed to flow from the oil outlet 603 to the oil absorbing member 5, on one hand, the cooling oil can be supplemented to the oil absorbing member 5, on the other hand, the acting force towards one side of the oil coating hole 501 can be exerted on the oil absorbing member 5, and the aperture of the oil absorbing member 5 near the oil outlet 603 is decreased, that is, the sewing needle 2 can still keep good contact with the side wall of the oil coating hole 501 in the ascending process.
In some embodiments, referring to fig. 1, the frame 1 is provided with a mounting seat 102 for mounting the sewing needle 2, the driving member 101 is fixedly mounted on the mounting seat 102, and the bottom of the driving member 101 abuts against the top of the lifting rod 606 for applying a downward force to the lifting rod 606. In this embodiment, the mounting seat 102 is used for driving the sewing needle 2 and the driving member 101 to reciprocate in the vertical direction. Because the driving member 101 and the sewing needle 2 move synchronously, when the sewing needle 2 moves downwards, the driving member 101 can synchronously drive the lifting rod 606 to move downwards, so that the bulge 609 on the air bag 604 passes through the through hole 605 and exerts force on the oil absorbing member 5, and the aperture of the area of the oil coating hole 501 close to the through hole 605 is ensured to be reduced when the sewing needle 2 passes through the oil coating hole 501 downwards. When the sewing needle 2 moves upwards, the driving member 101 and the sewing needle 2 move upwards synchronously, so that the driving member 101 is automatically separated from the lifting rod 606, the air bag 604 exerts an upward acting force on the pressing plate 607 by virtue of the elasticity of the air bag, the pressing plate 607 is reset, and the boss 609 retracts into the through hole 605.
In some embodiments, referring to fig. 1, a fan 7 is installed on the oil storage box 6, and the fan 7 is located at one side of the sewing needle 2 and faces the sewing needle 2, and increases a cooling effect on the sewing needle 2 by blowing air to the sewing needle 2. A gear 701 is attached to a rotating shaft of the fan 7, and a rack 103 engaged with the gear 701 is fixedly attached to the driver 101. The driving member 101 drives the rack 103 to reciprocate in the vertical direction, thereby driving the fan 7 to rotate around the shaft.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
