Description

Technical Field

[0001] This utility model belongs to the technical field of cable production equipment, and relates to a feeding device for a stranding machine. Background Technology

[0002] A stranding machine is a mechanical device that can twist multiple single wires into a single strand to meet the process requirements of cables. Stranding machines are widely used for various soft / hard conductor wires, such as copper wire, enameled wire, tin-plated wire, copper-clad steel, and copper-clad aluminum.

[0003] When leading wires, a stranding machine needs to feed multiple wires together before stranding them. The wires for stranding are typically wound on the unwinding drum and continuously released as the drum rotates. For some special cables, multiple wires need to be twisted into a single strand. However, existing unwinding mechanisms generally only support one or two drums. When multiple wires need to be twisted, multiple unwinding mechanisms are required, which not only takes up a lot of space and is difficult to arrange, but also makes it difficult to set up a matching merging mechanism to guide them into the stranding machine. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a feeding device for a stranding machine that can meet the feeding needs of multiple strands of wire, and has the advantages of small footprint and smooth wire feeding.

[0005] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0006] A feeding device for a stranding machine includes a feeding mechanism and a paralleling mechanism, wherein the paralleling mechanism is located between the feeding mechanism and the stranding machine. The feeding mechanism includes a high-low platform support, on which a low unwinding platform and a high unwinding platform are arranged front to back. A first unwinding unit and a second unwinding unit are arranged left to right on the low unwinding platform, and a third unwinding unit and a fourth unwinding unit are arranged left to right on the high unwinding platform. The paralleling mechanism gathers the wires from each unwinding unit and guides them to the stranding machine. The paralleling mechanism includes a vertical frame, on which a guide platform is arranged. A pair of vertically distributed rollers and a pair of horizontally distributed rollers are arranged on the guide platform. The vertical gap between the vertical rollers and the horizontal gap between the horizontal rollers together form a guide gap for the wires to pass through.

[0007] In the above-mentioned feeding device for a stranding machine, the high and low platform supports can be used individually or in pairs; using a single high and low platform support can meet the feeding requirements of four or fewer wires; using two high and low platform supports can meet the feeding requirements of five to eight wires. The structure is as follows: the feeding mechanism includes two high and low platform supports, which are arranged one after the other, and the high unwinding platforms of the two high and low platform supports are arranged adjacent to each other.

[0008] In the feeding device of the above-mentioned stranding machine, a pair of guide supports are provided on the guide platform, and vertical grooves are provided on the guide supports along the vertical direction. The horizontal roller can slide in the vertical grooves in an adjustable manner. Horizontal grooves are provided on the guide platform and are distributed from left to right. The vertical roller can slide in the horizontal grooves in an adjustable manner.

[0009] In the above-mentioned unwinding device of a stranding machine, the first unwinding unit and the second unwinding unit on the low unwinding platform are lower than the third unwinding unit and the fourth unwinding unit on the high unwinding platform; "lower than" means that the top of the unwinding unit on the low unwinding platform is lower than the bottom of the unwinding unit on the high unwinding platform; the unwinding units arranged on the left and right may have partial overlap in front and behind positions.

[0010] In the above-mentioned unwinding device of a stranding machine, the low unwinding platform and the high unwinding platform respectively include three platforms, left, middle and right, which are distributed at intervals. The two ends of the first unwinding unit and the third unwinding unit are respectively installed on the corresponding left and middle platforms, and the two ends of the second unwinding unit and the fourth unwinding unit are respectively installed on the corresponding middle and right platforms.

[0011] In the above-mentioned unwinding device of a stranding machine, the first unwinding unit, the second unwinding unit, the third unwinding unit and the fourth unwinding unit have the same structure, all including a drum, a movable support assembly and a fixed support assembly arranged coaxially. The end of the movable support assembly is rotatably provided with a movable support head that can move axially, and the end of the fixed support assembly is rotatably provided with a fixed support head. The movable support head and the fixed support head are respectively inserted into the two ends of the drum and form a fixed connection structure with it.

[0012] In the feeding device of the above-mentioned stranding machine, a tapered structure is provided between the fixed support head, the movable support head and the inner wall of the drum to cooperate with each other.

[0013] In the feeding device of the above-mentioned stranding machine, the movable support head is driven to move axially by a handwheel and a screw mechanism.

[0014] In the above-mentioned unloading device of a stranding machine, the outer ends of both the movable support component and the fixed support component are provided with fixed seats, which are fixed to the high unwinding platform and the low unwinding platform by welding.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This utility model provides a feeding device for a stranding machine. It adopts a high-low platform bracket with a low unwinding platform and a high unwinding platform to support the unwinding unit. Each high-low platform bracket can be equipped with four unwinding units, and the four unwinding units do not interfere with each other. Then, by setting a matching paralleling mechanism, the wires of the four unwinding units are gathered and guided to the stranding machine, thereby meeting the feeding requirements of multi-wire stranding.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 :

[0023] Example 1

[0024] A feeding device for a stranding machine includes a feeding mechanism and a paralleling mechanism, wherein the paralleling mechanism is located between the feeding mechanism and the stranding machine. The feeding mechanism includes a high-low platform support 1, on which a low unwinding platform 2 and a high unwinding platform 3 are arranged front to back. A first unwinding unit 4 and a second unwinding unit 5 are arranged left to right on the low unwinding platform 2, and a third unwinding unit 6 and a fourth unwinding unit 7 are arranged left to right on the high unwinding platform 3. The paralleling mechanism gathers the wires from each unwinding unit and guides them to the stranding machine. The paralleling mechanism includes a stand 8, on which a guide platform 9 is arranged. A pair of left-right distributed vertical rollers 10 and a pair of up-down distributed horizontal rollers 11 are arranged on the guide platform 9. The vertical gap between the vertical rollers 10 and the horizontal gap between the horizontal rollers 11 together form a guide gap for the wires to pass through.

[0025] Comparison Appendix Figure 1In this embodiment, the first unwinding unit 4, the second unwinding unit 5, the third unwinding unit 6, and the fourth unwinding unit 7 can each provide a single wire. Alternatively, only some of the unwinding units can be used. The wires in the first unwinding unit 4, the second unwinding unit 5, the third unwinding unit 6, and the fourth unwinding unit 7 are guided to the winding mechanism from the lower left, lower right, upper left, and upper right positions, respectively, without interfering with each other. (Refer to the attached diagram.) Figure 2 The wire-splitting mechanism guides the wires to the stranding machine after they are wired together. The wire-splitting is accomplished by a pair of vertical rollers 10 distributed left and right and a pair of horizontal rollers 11 distributed up and down. The vertical rollers 10 limit the left and right position of the wires, and the horizontal rollers 11 limit the up and down position of the wires, thereby merging the wires together.

[0026] To meet diverse lane-merging requirements, the lane-merging position defined by the lane-merging mechanism in this embodiment can be slightly adjusted. Specifically, the guide platform 9 is provided with a pair of guide supports 12, each with vertically distributed vertical grooves 13. The horizontal roller 11 can adjustably slide within the vertical grooves 13. The guide platform 9 is also provided with horizontally distributed horizontal grooves 14, where the vertical roller 10 can adjustably slide within the horizontal grooves 14. The vertical grooves allow for adjustment of the vertical and horizontal positions of the lane-merging mechanism, while the horizontal grooves 14 allow for adjustment of the horizontal and vertical positions. This adjustment is achieved through a screw and a locking nut.

[0027] To further avoid interference between the unwinding units, the first unwinding unit 4 and the second unwinding unit 5 on the low unwinding platform 2 are lower than the third unwinding unit 6 and the fourth unwinding unit 7 on the high unwinding platform 3. "Lower than" means that the top of the unwinding unit on the low unwinding platform 2 is lower than the bottom of the unwinding unit on the high unwinding platform 3. The unwinding units arranged on the left and right can have some overlap in front and behind.

[0028] Furthermore, in order to make the structure more compact, the low unwinding platform 2 and the high unwinding platform 3 each include three platforms that are spaced apart: left, middle and right. The two ends of the first unwinding unit 4 and the third unwinding unit 6 are respectively installed on the corresponding left and middle platforms, and the two ends of the second unwinding unit 5 and the fourth unwinding unit 7 are respectively installed on the corresponding middle and right platforms.

[0029] Comparison Appendix Figure 3The first unwinding unit 4, the second unwinding unit 5, the third unwinding unit 6, and the fourth unwinding unit 7 have the same structure, each including a drum 15, a movable support assembly 16, and a fixed support assembly 17 arranged coaxially. The end of the movable support assembly 16 is rotatably provided with a movable support head that can move axially, and the end of the fixed support assembly 17 is rotatably provided with a fixed support head. The movable support head and the fixed support head are respectively inserted into both ends of the drum 15 and form a fixed connection structure with it.

[0030] In this embodiment, the drum 15 is clamped by a movable support head and a fixed support head, while the drum 15 can also rotate freely. The clamping method is as follows: first, one end of the drum 15 is put into the fixed support head, and then the movable support head is moved and inserted into the other end of the drum 15 until the drum 15 is clamped.

[0031] The aforementioned fixed support head, movable support head and inner wall of the drum 15 are provided with a matching conical structure. The diameter of the conical structure on the inner wall of the drum 15 gradually increases from the inside to the outside. The conical structure forms an axial positioning structure between the fixed support head, movable support head and drum 15, so that the fixed support head and movable support head can easily clamp the drum 15.

[0032] The outer ends of the aforementioned movable support component 16 and fixed support component 17 are each provided with a fixing seat, which is fixed to the high unwinding platform 3 and the low unwinding platform 2 by welding.

[0033] The aforementioned movable support head is driven to move axially by a handwheel and a lead screw mechanism. The lead screw mechanism is screwed into the fixed base, and the movable support head is rotatably mounted at the end of the lead screw mechanism. By rotating the lead screw with the handwheel, the lead screw moves axially relative to the fixed base, thereby driving the movable support head to move axially.

[0034] Example 2

[0035] In this embodiment, the structure of the high and low platform support 1 is the same as that in embodiment 1, but two high and low platform supports 1 are used. Using two high and low platform supports 1 can meet the feeding requirements of five to eight wires. The specific structure is as follows: the feeding mechanism includes two high and low platform supports 1, which are arranged one after the other, and the high unwinding platform 3 of the two high and low platform supports 1 are arranged adjacent to each other.

[0036] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
