Description

[0002] In fiberglass wire drawing production, there are usually two types of wire drawing machines, namely direct yarn wire drawing machines and cake yarn wire drawing machines. Their speeds are high or low, and the high-speed centrifugal force is very large. The head diameter of the direct yarn wire drawing machine is relatively small, and the flapper telescoping is mainly carried out by the two end tapered sleeves. Due to insufficient space, the thrust of the middle tapered sleeve is small and can only be used as an auxiliary telescoping. The middle tapered sleeves must also be symmetrically arranged, occupying a large space. On the contrary, the head diameter of the cake yarn wire drawing machine is relatively large. Usually, the aluminum rotating cylinder is large and long. The front half part is hollowed out, and the middle part of the rear half part is fixed by taper fitting with the main shaft. The extension of the head length is completed by the aluminum rotating cylinder to be the same length as the flapper. However, for a longer flapper, the stiffness of the middle part will inevitably be affected. The existing flapper telescopic mechanism is prone to soft waist due to insufficient jacking force.

[0028] On the side of the installation position 70 of the telescopic mechanism opposite to the piston cavity 730, several seat holes 710 for the top spring are also arranged; on the side of the ramp slider ring 20 close to the seat holes 710 for the top spring, there are jacks 220 for the top spring, the positions of the jacks 220 for the top spring are opposite to the seat holes 710 for the top spring and their numbers are the same; one end of the top spring 50 of the slider ring is placed in the seat holes 710 for the top spring, and the other end is placed in the jacks 220 for the top spring, and the top spring 50 of the slider ring is in contact with the inner side surfaces of the seat holes 710 for the top spring and the jacks 220 for the top spring respectively.

[0029] On the same side of the telescopic mechanism installation position 70 as the piston chamber 730, a number of connecting rod holes 720 are also provided. At the opening part of the connecting rod holes 720, there is a connecting rod movable opening 740; on the connecting rod slider 30, there is a rod head accommodating position 320, and at the opening part of the rod head accommodating position 320, there is a rod head movable opening 340; the connecting rod 40 includes a connecting rod part 410 and connecting rod heads 420 arranged at both ends of the connecting rod part 410; the connecting rod heads 420 at both ends of the connecting rod part 410 are respectively movably assembled in the rod head accommodating position 320 and the connecting rod holes 720.

[0030] On the connecting rod slider 30, there is a slider tension spring groove 330. The slider tension spring 60 is arranged in the slider tension spring groove 330, and the slider tension spring 60 surrounds the connecting rod slider 30 to provide a radial contraction force for the connecting rod slider 30.

[0031] The connecting rod slider 30, the connecting rod 40, and the slider ring top spring 50 are evenly distributed in a ring shape within the telescopic mechanism installation position 70. The number of the connecting rod slider 30, the connecting rod 40, and the slider ring top spring 50 is equal to that of the ramp slider grooves 210. Among them: the number of the connecting rod slider 30, the connecting rod 40, and the slider ring top spring 50 can be flexibly configured according to actual needs, and the number is at least 4. In this embodiment, the number of the connecting rod slider 30, the connecting rod 40, and the slider ring top spring 50 is 12. Correspondingly, the number of the ramp slider grooves 210 on the ramp slider ring 20 is also 12.

[0032] It further includes a ventilation passage 80, and the ventilation passage 80 is communicated with the piston chamber 730.

[0033] This application provides a flapper telescopic mechanism for a modular multi-point pulling head, adopting a flapper telescopic mechanism composed of a piston ring, a ramp slider ring, a connecting rod slider, a connecting rod, a slider ring top spring, and a slider tension spring. When the connecting rod slider is subjected to a driving force, it can quickly respond, which is beneficial to reducing the system response time and improving the control accuracy and efficiency. At the same time, through the normal force and radial supporting force of the connecting rod, the efficiency of the flapper telescoping can be guaranteed, and the stability of the flapper telescoping action can be improved.

[0034] The specific operation principle is as follows:

[0035] After connecting compressed air and the compressed air enters the piston chamber 730 through the ventilation passage 80, it drives the piston ring 10 and simultaneously pushes the ramp slider ring 20 to move towards the connecting rod slider 30, compressing the slider ring top spring 50; at the same time, after the connecting rod slider 30 loses the supporting effect of the ramp slider ring 20, it slides down along the ramp slider groove 210 under the action of the slider tension spring 60. After the flapper of the head loses the supporting effect of the connecting rod slider 30, it radially contracts under the action of the flapper tension spring.

[0036] Disconnect the compressed air. Under the action of the slide ring top spring 50 of the ramp slide block, the piston ring 10 is pushed into the piston ring cavity 730 by the ramp slide block ring 20. At the same time, the connecting rod slide block 30 slides upward along the ramp slide block groove 210, and the head expanding piece expands under the holding action of the connecting rod slide block 30.

[0037] When the connecting rod slide block 30 slides upward or downward along the ramp slide block groove 210, the connecting rod 40 and the ramp slide block groove 210 limit the up-and-down sliding range of the connecting rod slide block 30 within a fixed range, so that when subjected to the upward or downward driving force, the connecting rod slide block 30 can quickly make an effective response, reduce the ineffective upward or downward sliding stroke, reduce the system response time, and improve the control accuracy and efficiency.

[0038] At the same time, when lifting the head expanding piece, the connecting rod 40 can also provide a normal limiting force (parallel to the head main shaft direction) to the connecting rod slide block 30 to prevent the connecting rod slide block 30 from generating displacement on the head expanding piece along the direction parallel to the head main shaft when being pushed by the ramp slide block groove 210, and further ensure the efficiency of the head expanding piece extension. Moreover, during the process of lifting the head expanding piece, the connecting rod 40 can also provide a radial supporting force to the connecting rod slide block 30, and a part of the reaction force from the head expanding piece is borne by the connecting rod 40, so as to balance the force on the ramp slide block ring 20 and improve the stability of the expanding piece extension action.

[0039] On the wire drawing machine with a multi-strand ultra-long head, as the length of the expanding piece increases, the middle part of the expanding piece is prone to bending (soft waist). The conical sleeve arranged in the middle of the expanding piece on the existing wire drawing machine cannot solve the soft waist problem due to insufficient thrust, thus limiting the development of the head length. This application adopts a self-developed new expanding piece telescopic mechanism to cooperate with the operation of the long head, which not only solves the soft waist problem that is prone to occur in the longer expanding piece, but also can reduce the system response time, improve the control accuracy and control efficiency, and increase the stability of the expanding piece telescopic movement.

[0040] The technical solutions and technical effects of this application have been elaborated in detail above in combination with the specification drawings and specific embodiments. It should be noted that those skilled in the art can also develop other embodiments on this basis; any simple deformation and equivalent replacement that do not depart from the innovative concept of this application are covered by this application and belong to the protection scope of this patent.
