The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1 to 5, the present invention provides an upper stop feeding mechanism 100 for feeding upper stops in a zipper manufacturing process. The upper stop feeding mechanism 100 includes a support plate 1, a first feeding device 3, and a second feeding device 5.
The supporting plate 1 is fixedly connected with a frame of the zipper manufacturing machine and is used for supporting the first feeding device 3 and the second feeding device 5. The first feeding device 3 and the second feeding device 5 are spaced from each other and symmetrically arranged at two opposite ends of the supporting plate 1.
Specifically, the support plate 1 includes a first support plate 11 disposed along a horizontal direction and a second support plate 13 disposed along a vertical direction, where the horizontal direction is a direction shown by an X axis in fig. 1, and the vertical direction is a direction shown by a Z axis in fig. 1. The first support plate 11 and the second support plate 13 are fixedly connected and perpendicular to each other.
The first feeding device 3 and the second feeding device 5 have the same structure, and specifically, the first feeding device 3 includes a driving device 31, a slide bar 33, a feeding unit 35, and an upper stop block 37.
The driving device 31 is disposed at one end of the first support plate 11. Preferably, the driving device 31 is a cylinder, and the type of the cylinder is one or more selected from QGB, QGS, and JB.
Further, the driving device 31 includes a piston rod 311, and air expands in the driving device 31 to convert thermal energy into mechanical energy, thereby driving the piston rod 311 to reciprocate in a vertical direction.
The slide bar 33 is disposed below the driving device 31 and fixed to the second support plate 13. Specifically, the slide actuating rod 33 includes a transmission block 331, a straight rod 333, a curved rod 335, and a rotation shaft 337. The transmission block 331, the straight rod 333 and the curved rod 335 are sequentially connected, the curved rod 335 is fixed on the second support plate 13 by the rotating shaft 337, and the curved rod 335 can freely rotate around the rotating shaft 337.
The driving block 331 is disposed opposite to the piston rod 311, preferably, an accommodating groove 3311 is formed at a recessed end of the driving block 331 close to the piston rod 311, an opening of the accommodating groove 3311 matches a cross-sectional size of the piston rod 311, and when the driving device 31 drives the piston rod 311 to move vertically and downwardly, the piston rod 311 is correspondingly accommodated in the accommodating groove 3311, and a driving force of the driving device 31 is transmitted to the slide bar 33.
One end of the straight rod 333 is hinged to the transmission block 331, and the other end is hinged to the curved rod 335, so as to further transmit the driving force of the driving device 331 to the curved rod 335. It will be appreciated that the straight rod 333 and the curved rod 335 cooperate to form a linkage mechanism that converts linear motion of the piston rod 311 into rotational motion of the curved rod 335.
The bell crank 335 includes a first end 3351 and a second end 3353 disposed opposite one another. The second end 3353 is formed with a track-shaped through hole 3355, and the through hole 3355 completely penetrates through two sides of the curved bar 335.
The feeding unit 35 is arranged obliquely relative to the vertical direction, so that the upper stop can conveniently slide downwards along the feeding unit 35 under the action of gravity, no additional power is needed, and energy is saved. Preferably, the inclination angle of the feeding unit 35 is 50 to 70 °.
The feeding unit 35 includes a first feeding unit 351, a second feeding unit 353 coupled to the first feeding unit 351, and a fixing block 355 connecting the first feeding unit 351 and the second feeding unit. The first feeding unit 351 and the second feeding unit 353 are spaced from each other, and the number of the fixing blocks 355 is multiple, so that on one hand, a good fixing effect can be achieved, on the other hand, the distance between the first feeding unit 351 and the second feeding unit 353 can be kept consistent, and the phenomenon that the first feeding unit 351 or the second feeding unit 353 deviates and the upper stop is blocked in the operation process is avoided. Preferably, the fixing block 355 is connected with the first feeding unit 351 and the second feeding unit 353 through screws or bolts, so that the first feeding unit 351 and the second feeding unit 353 can be conveniently replaced, maintenance is convenient, and the use requirements of different models of top stops can be met.
The first feeding unit 351 is provided with a first protrusion 3511 towards the direction close to the second feeding unit 353, the second feeding unit 353 is provided with a sliding groove 3531 towards the direction far away from the first feeding unit 351 in a concave mode, the upper stop is U-shaped, the cross section of the first protrusion 3511 is matched with the shape of the upper stop, and the peripheral area of the first protrusion 3511 and the sliding groove 3531 are matched to form a U-shaped feeding slideway. During feeding, the upper stop enters from the upper end of the feeding unit 35 and is sleeved on the first protrusion 3511, and after feeding, the upper stop slides downwards to the upper stop block 37 along the feeding slide way under the action of gravity. It can be understood that the second feeding unit 353 also limits the deviation of the upper stop, and prevents the upper stop from falling off during falling. Preferably, the outer surface of the first protrusion 3511 is a smooth surface, so that the resistance of the upper and lower slides can be reduced.
The upper push-up block 37 is disposed at the bottom end of the feeding unit 35, and specifically, the upper push-up block 37 includes a bearing table 371 and a connecting rod 373 connected to the bearing table 371. The upper surface of the susceptor 371 abuts against the lower surface of the feeding unit 35.
Further, the carrier 371 includes an upper portion 3711 and a lower portion 3713, a second protrusion 3715 matching with the first protrusion 3511 is formed at one end of the upper portion 3711 close to the second feeding device 5, a projection of the second protrusion 3715 to the lower portion 3713 completely falls within the range of the lower portion 3713, and the second protrusion 3715 and the lower portion cooperate to form a step-like structure. It is understood that, before the upper stop feeds, the second protrusion 3715 coincides with the first protrusion 3511, and when the upper stop feeds, the upper stop slides down along the feeding unit 35 to the upper stop block 37, and at this time, the upper stop is sleeved on the second protrusion 3715 and is carried on the lower portion 3713.
Furthermore, the upper portion 3711 and the lower portion 3713 are detachably connected through screws or other methods, so that the upper portion 3711 can be replaced conveniently to meet the use requirements of different models of upper stoppers.
The connection rod 373 penetrates the through hole 3355, and preferably, an end of the connection rod 373 connected to the through hole 3355 is cylindrical. The resistance of the connecting rod 373 to the curved rod 335 during relative movement can be reduced, and a roller structure can be further added to the end of the connecting rod 373 connected to the through hole 3355, so as to further reduce the friction resistance.
The operation process of the upper stop feeding mechanism is as follows:
the upper stopper is placed on the top end of the feeding unit 35 and sleeved on the first protrusion 3511, and it is understood that the process can be manually operated or a corresponding mechanical structure is adopted; the upper stop slides down to the upper stop block 37 along the feeding slideway under the action of gravity and is correspondingly sleeved on the second bulge 3715; the driving device 31 drives the piston rod 311 to move vertically downward and penetrate into the accommodating slot 3311, so as to drive the transmission block 331 to move vertically downward, and transmit the motion state to the curved bar 335 through the straight bar 333, the first end 3351 of the curved bar 335 rotates around the rotation axis 353 along the counterclockwise direction, and simultaneously, the second end 3353 rotates around the rotation axis 353 along the counterclockwise direction, at this time, the curved bar 351 rotates around the connection rod 373 as a whole, so as to apply a pushing force to the connection rod 373, so that the connection rod 373 and the bearing table 371 move to the loading position along the preset direction to complete the loading operation.
Correspondingly, the second feeding device 5 comprises a driving device 51, a slide bar 53, a feeding unit 55 and an upper push block 57, the mechanism of which is consistent with the corresponding structure of the first feeding device 3, and the first feeding device 3 and the second feeding device 5 are symmetrically arranged. Specifically, the driving device 31 of the first feeding device 3 and the driving device 51 of the second feeding device 5 are symmetrically arranged at two opposite ends of the first supporting plate 11; the slide bar 33 of the first feeding device 3 and the slide bar 53 of the second feeding device 5 are symmetrically arranged on two opposite sides of the second supporting plate 13.
It can be understood that the driving device of the first feeding device 3 and the driving device of the second feeding device 5 work independently without affecting the working state of each other, so that the first feeding device 3 and the second feeding device 5 can complete the feeding operation independently. For example: the first feeding device 3 and the second feeding device 5 can select different types of top stops to feed respectively; when the first feeding device 3 is in fault maintenance, the second feeding device 5 can still complete feeding without stopping, so that the working efficiency is ensured to a certain extent; when the first feeding device 3 feeds materials independently, the second feeding device 5 does not need to be cleaned, so that the operation time is saved.
