Description

Technical Field

[0001] This application belongs to the technical field of fiberglass production, and particularly relates to a multi-filament drawing machine head with a new modular structure. Background Art

[0002] In fiberglass drawing production, there are usually two types of drawing machines, namely direct yarn drawing machines and cake yarn drawing machines. Their speeds vary, and the high-speed centrifugal force is very large. The head diameter of the direct yarn drawing machine is relatively small, and the expansion and contraction of the expanding piece are mainly driven by the cone sleeves at both ends. Due to insufficient space, the thrust of the middle cone sleeve is small and can only be used as an auxiliary expansion and contraction. The middle cone sleeves must also be symmetrically arranged, occupying a large space. On the contrary, the head diameter of the cake yarn 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 fit with the main shaft. The extension of the head length is completed by the aluminum rotating cylinder to be the same length as the expanding piece. However, the processing of the long aluminum rotating cylinder and the expanding piece is difficult. Especially for the aluminum rotating cylinder, complex processes such as drilling deep holes, turning tapers, milling T-shaped grooves, and processing stress relief are involved, which are prone to damage and require a large amount of work. Moreover, it is difficult to guarantee the quality, especially causing troubles to users in terms of maintenance. The ultra-long and overweight aluminum rotating cylinder is very difficult to install and disassemble, with high requirements. At the same time, if the length of the expanding piece is large, the stiffness of the middle part will inevitably be affected. The existing expanding piece expansion and contraction mechanism is prone to soft waist due to insufficient jacking force. Summary of the Utility Model

[0037] Direction convention: Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2The completed headstock is assembled by splicing along the omitted arc. In this application, the front direction refers to the end of the headstock away from the motor base, and the direction opposite to the front is the rear direction. Correspondingly, the front end of a component or assembly refers to the end farther from the motor base, and the rear end of a component or assembly refers to the end closer to the motor base.

[0038] Please refer to Figures 1-6 , the multi-strand drawing machine headstock with a novel modular structure disclosed in this application includes a headstock spindle 10, an upper wire ring 20, a pull rod seat 30, a broken-bridge expanding piece 40, and several segmented aluminum rotating cylinders 50. The number of segments of the segmented aluminum rotating cylinder 50 is flexibly configured according to the actual required number of strands for drawing. In this embodiment, it includes three segmented aluminum rotating cylinders 50.

[0039] All three segmented aluminum rotating cylinders 50 are fixedly assembled on the headstock spindle 10. The upper wire ring 20 is fixedly assembled at the front end of the headstock spindle 10. The pull rod seat 30 is fixedly assembled on the headstock spindle 10 and is located behind the segmented aluminum rotating cylinder 50. The broken-bridge expanding piece 40 is snap-fitted on the segmented aluminum rotating cylinder 50.

[0040] Between the upper wire ring 20 and the segmented aluminum rotating cylinder 50, between the segmented aluminum rotating cylinder 50 and the pull rod seat 30, and between every two adjacent segmented aluminum rotating cylinders 50, there is a telescopic mechanism assembly position 60, and a expanding piece telescopic mechanism 70 is arranged in the telescopic mechanism assembly position 60.

[0041] Please refer to Figure 4 , the segmented aluminum rotating cylinder 50 is provided with a snap-fitting position, and the connecting part of the broken-bridge expanding piece 40 has a structure that coincides with the snap-fitting position. When the broken-bridge expanding piece 40 is movably snap-fitted in the snap-fitting position, this movable snap-fitting connection can prevent the broken-bridge expanding piece 40 from falling off radially. For the movable snap-fitting connection between the rotating cylinder and the expanding piece, please refer to the Chinese patent: A Headstock Expanding Piece Intermediate Cone Sleeve Support Device (publication number: CN213803526U).

[0042] Both ends of the broken-bridge expanding piece 40 are provided with expanding piece spring grooves 420, and several expanding piece broken-bridge grooves 410 are arranged in the length direction of the broken-bridge expanding piece 40. The expanding piece broken-bridge grooves 410 are evenly distributed in the length direction of the broken-bridge expanding piece 40, and each expanding piece broken-bridge groove 410 corresponds to a telescopic mechanism assembly position 60 and an expanding piece telescopic mechanism 70.

[0043] The expanding piece telescopic mechanism 70 includes a piston ring 710, a ramp slider ring 720, a connecting rod slider 730, a connecting rod 740, a slider ring top spring 750, a slider spring 760, and an expanding piece spring 770.

[0044] The segmented aluminum rotary cylinder 50 and the pull rod seat 30 are both provided with piston ring assembly grooves 5030. The piston ring 710 is fixedly assembled on the main shaft 10 of the machine head through its assembly shaft hole. The piston ring assembly groove 5030 and the main shaft 10 of the machine head define a piston ring driving cavity, and the piston ring 710 is assembled in the piston ring driving cavity.

[0045] The ramp slider ring 720 is fixedly assembled on the main shaft 10 of the machine head through its assembly shaft hole and is in contact and cooperation with the piston ring 710.

[0046] A number of ramp slider grooves 7210 are provided on the ramp slider ring 720, and a ramp mating portion 7310 is provided on the link slider 730. The link slider 730 is assembled in the ramp slider groove 7210, and the ramp mating portion 7310 and the ramp slider groove 7210 are mutually cooperated through ramps with matching structures.

The spherical connecting rod heads 7420 at both ends of the connecting rod 740 are respectively movably connected to the block upper rod head accommodation position 7330 and the rod head mating accommodation position 5031.

[0050] The size of the connecting rod head 7420 is larger than the sizes of the block upper rod head movable opening 7340 and the rod head mating movable opening 5032. When the link slider 730 moves upward or downward along the ramp slider groove 7210, the connecting rod head 7420 can move within the block upper rod head accommodation position 7330 and the rod head mating accommodation position 5031, but cannot be disengaged from the block upper rod head accommodation position 7330 and the rod head mating accommodation position 5031.

[0051] Both the segmented aluminum rotary cylinder 50 and the wire feeding ring 20 are provided with top spring seat holes 5020. A top spring insertion hole 7220 is provided on the ramp slider ring 720. Both ends of the slider ring top spring 750 are respectively arranged in the top spring seat hole 5020 and the top spring insertion hole 7220. When the piston ring 710 pushes the ramp slider ring 720 to compress the slider ring top spring 750, the slider ring top spring 750 can apply a force to the side of the ramp slider ring 720 opposite to the piston ring 710 through the elastic restoring force.

[0052] The connecting rod slider 730 is provided with a tension spring groove 7320, and the slider tension spring 760 is arranged in the tension spring groove 7320. The slider tension spring 760 surrounds the connecting rod slider 730 to provide a radial contraction force for the connecting rod slider 730.

[0053] The expansion piece tension spring 770 is arranged in the expansion piece tension spring grooves 420 at both ends of the broken bridge type expansion piece 40. The expansion piece tension spring 770 surrounds in a plurality of expansion piece tension spring grooves 420 to provide a radial contraction force for the broken bridge type expansion piece 40.

[0054] The main shaft of the machine head 10 is provided with a main shaft air circuit 110, and the main shaft air circuit 110 communicates with the piston ring drive chamber.

[0055] The number of the connecting rod sliders 730, the connecting rods 740, the slider ring top springs 750 and the number of the ramp slider grooves 7210 can be flexibly configured according to the diameter of the segmented aluminum rotary drum 50. In this embodiment, the number of the connecting rod sliders 730, the connecting rods 740 and the slider ring top springs 750 is 12, and the number of the ramp slider grooves 7210 is also 12.

[0056] Principle and effect description:

[0057] When compressed air is turned on, the piston ring 710 pushes the ramp slider ring 720 to move forward, compressing the slider ring top spring 750; at the same time, after the connecting rod slider 730 loses the supporting effect of the ramp slider ring 720, it slides down along the ramp slider groove 7210 under the action of the slider tension spring 760, and the broken bridge type expansion piece 40 radially contracts under the action of the expansion piece tension spring 770 after losing the supporting effect of the connecting rod slider 730.

[0058] When the compressed air is turned off, the ramp slider ring 720 pushes the piston ring 710 into the piston ring drive chamber under the action of the slider ring top spring 750; at the same time, the connecting rod slider 730 slides up along the ramp slider groove 7210, and the broken bridge type expansion piece 40 expands under the supporting action of the connecting rod slider 730.

[0059] When the connecting rod slider 730 slides up or down along the ramp slider groove 7210, the connecting rod 740 and the ramp slider groove 7210 limit the up and down sliding range of the connecting rod slider 730 within a fixed range, so that when the upward sliding driving force or the downward sliding driving force is received, the connecting rod slider 730 can quickly make an effective response, reduce the ineffective upward sliding or ineffective downward sliding stroke, reduce the system response time, and improve the control accuracy and efficiency.

[0060] Meanwhile, when the expanding piece is lifted, the connecting rod 740 can also provide a normal limiting force (parallel to the main shaft 10 of the machine head) to the connecting rod slider 730, preventing the connecting rod slider 730 from displacing on the expanding piece in the direction parallel to the main shaft 10 of the machine head when being pushed by the ramp slider groove 7210, and further ensuring the efficiency of the expansion of the expanding piece. Moreover, during the process of lifting the expanding piece, the connecting rod 740 can also provide a radial supporting force to the connecting rod slider 730, and a part of the reaction force from the expanding piece is borne by the connecting rod 740, thereby being able to balance the force on the ramp slider ring 720 and improving the stability of the telescopic movement of the expanding piece.

[0061] As the length of the expanding piece increases, it is inevitable that 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 restricting the development of the length of the machine head. The present application adopts a newly developed expanding piece telescopic mechanism to cooperate with the operation of the long machine head, which not only solves the soft waist problem that is prone to occur in longer expanding pieces, but also can reduce the system response time, improve the control accuracy and control efficiency, and increase the stability of the telescopic movement of the expanding piece.

[0062] Meanwhile, since a plurality of expanding piece breaking bridges 410 are arranged on the broken bridge type expanding piece 40, the bending deformation points of the longer expanding piece during operation will be concentrated on the positions of the expanding piece breaking bridges 410, and a corresponding expanding piece telescopic mechanism 70 is arranged at each position of the expanding piece breaking bridge 410. Therefore, even for an extremely long and lightweight and easily deformable expanding piece, no soft waist phenomenon will occur during operation. Thus, the multi-strand wire drawing machine head with the newly disclosed novel modular structure also allows for the lightweight development of the expanding piece, so as to reduce the installation difficulty of the expanding piece and the centrifugal force during operation, reduce the power consumption of the wire drawing machine, and improve the control accuracy of the telescopic movement of the expanding piece.

[0063] In a variant embodiment of the present application, the multi-strand wire drawing machine head with the novel modular structure further includes a machine head front end cover 80, a machine head rear end cover 90, a dust-proof labyrinth 100, and a protective cover 200; the machine head front end cover 80 is fixedly assembled on the wire feeding ring 20, and the machine head rear end cover 90, the dust-proof labyrinth 100, and the protective cover 200 are fixedly connected to the pull rod seat 30.

[0064] In a variant embodiment of the present application, the multi-strand wire drawing machine head with the novel modular structure further includes a bearing seat 300, a coupling 400, a driving motor 500, and a motor seat 600; the main shaft 10 of the machine head is fixedly connected to the power output shaft of the driving motor 500 through the coupling 400, the coupling 400 is assembled in the motor seat 600, and the bearing seat 300 is fixedly assembled between the machine head rear end cover 90 and the motor seat 600.

[0065] The technical solutions and technical effects of the present application have been elaborated in detail in combination with the accompanying drawings of the specification 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 the present application are covered by the present application and belong to the protection scope of this patent.
