Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire stranding device technology, specifically a wire and cable stranding device. Background Technology
[0002] Electric wires and cables are commonly used devices for transmitting electrical energy or signals, typically consisting of a single wire or several wires. Twisting is a crucial step in their production, and twisting devices are widely used as common twisting equipment.
[0003] The wire stranding device includes structures such as a wire feeder, a wire distributor, and a wire take-up device. The wire distributor is used to arrange the wires fed out by the wire feeder and rotates together with the wire feeder to wind the wires onto the main wire. However, most current wire distributors use wire holes for threading. Because these are closed wire holes, the wires can only be threaded one by one, resulting in low threading efficiency and inconvenience for wire arrangement. Therefore, a wire and cable stranding device is needed to solve the above problems. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model discloses a wire and cable stranding device. The technical solution adopted is as follows: A base is provided, and a mounting hole is provided at the lower end of the base; a bearing plate is provided at the upper rear end of the base, and a rotating ring is rotatably arranged inside the bearing plate. Limiting half-holes are evenly arranged around the inner side of the rotating ring; a hollow rotating shaft with front and rear openings is provided at the axis of the rotating ring, and the rear end of the rotating shaft is connected to the rear side of the rotating ring through a mounting bracket. A connecting screw hole is provided on the mounting bracket, and a connecting lug is provided at the rear end of the rotating shaft; a wire splitting unit is provided on the rotating shaft, and the wire splitting unit includes a connecting bushing, a primary wire splitting wheel, a wire splitting half-hole, and a secondary wire splitting wheel. The connecting bushing is movably sleeved on the rotating shaft, and the primary and secondary wire splitting wheels are fixedly sleeved on the connecting bushing. The thread spool is located behind the secondary thread spool, and the diameter of the secondary thread spool is smaller than that of the primary thread spool. The primary thread spool can be fixedly connected to the mounting bracket. The thread splitting half-hole is opened around the outer perimeter of the primary and secondary thread spools and corresponds to the limiting half-hole. The thread splitting half-hole of the primary thread spool can be combined with the limiting half-hole to form a circular hole, which is supported by the base. The mounting hole facilitates the installation of the base into the external space. The main wire to be wound passes through the inside of the rotating shaft. The connecting ear facilitates the connection to the rotating shaft of the wire feeder, thereby driving the rotating shaft to rotate synchronously. The wire to be wound is guided through the circular hole formed by the combination of the thread splitting half-hole and the limiting half-hole. Its detachable design facilitates the placement of the wire into the corresponding circular hole. The thread splitting half-hole of the secondary thread spool reduces the distance between each wire, thereby facilitating winding on the main wire.
[0005] As a preferred technical solution of the wire and cable stranding device of this utility model, a limiting protrusion is provided on the outer side of the rotating shaft from front to back, and a limiting groove is provided on the connecting shaft sleeve to cooperate with the limiting protrusion. The limiting protrusion and the limiting groove can increase the degree of cooperation between the rotating shaft and the connecting shaft sleeve, and at the same time restrict the movement direction of the connecting shaft sleeve, so as to facilitate the corresponding connection between the primary wire separating wheel and the mounting frame.
[0006] As a preferred technical solution of the wire and cable stranding device of this utility model, there are several secondary wire-distributing wheels, and the diameter of the several secondary wire-distributing wheels decreases from back to front. By using several secondary wire-distributing wheels with successively decreasing diameters, the distance between the wires can be reduced smoothly, preventing them from tangling.
[0007] As a preferred technical solution of the wire and cable stranding device of this utility model, a chamfer is provided on the inner side of the branching half hole. By setting the chamfer of the branching half hole, the wear of the wire can be reduced.
[0008] As a preferred technical solution of the wire and cable stranding device of this utility model, the primary wire separating wheel is provided with a connecting bolt, and the connecting bolt is connected to the connecting screw hole.
[0009] As a preferred technical solution of the wire and cable stranding device of this utility model, a guide post is provided at the upper front end of the base, and a guide ring is provided at the upper end of the guide post. The guide ring and the rotating shaft are coaxial, and there is a space between the guide ring and the rotating shaft. The main wire and the wire are wound through the space between the guide ring and the rotating shaft, and the wound cable is discharged through the guide ring.
[0010] The beneficial effects of this utility model are as follows: This utility model is supported by a base, and the mounting holes facilitate the installation of the base into an external space. The main wire to be wound passes through the interior of the rotating shaft, and the connecting ear facilitates the connection to the rotating shaft of the wire feeder, thereby driving the rotating shaft to rotate synchronously. The wire to be wound is guided through a circular hole formed by the combination of the wire dividing half hole and the limiting half hole. Its detachable design facilitates the placement of the wire into the corresponding circular hole. The wire dividing half hole of the secondary wire dividing wheel reduces the distance between each wire, thus facilitating winding on the main wire. The limiting protrusion and limiting groove increase the fit between the rotating shaft and the connecting bushing, while limiting the movement direction of the connecting bushing, facilitating the corresponding connection between the primary wire dividing wheel and the mounting frame. Several secondary wire dividing wheels with successively decreasing diameters can smoothly reduce the distance between the wires, preventing them from tangling. The chamfered setting of the wire dividing half hole reduces wire wear. The main wire and wire are wound through the space between the guide ring and the rotating shaft, and the wound cable is discharged through the guide ring. Attached Figure Description

Detailed Implementation
[0016] Example 1
[0017] like Figures 1 to 4As shown, this utility model discloses a wire and cable stranding device. The technical solution adopted is as follows: it includes a base 1, with a mounting hole 101 at the lower end of the base 1; a support plate 2 is provided at the upper rear end of the base 1, and a rotating ring 201 is rotatably provided inside the support plate 2. Limiting half holes 202 are evenly provided around the inner side of the rotating ring 201; a rotating shaft 3 with a hollow interior and front and rear openings is provided at the axis of the rotating ring 201, and the rear end of the rotating shaft 3 is connected to the rear side of the rotating ring 201 through a mounting bracket 301. A connecting screw hole 302 is provided on the mounting bracket 301, and a connecting lug 303 is provided at the rear end of the rotating shaft 3.A branching unit 4 is provided on the rotating shaft 3. The branching unit 4 includes a connecting sleeve 41, a primary branching wheel 42, a branching half-hole 43, and a secondary branching wheel 44. The connecting sleeve 41 is movably sleeved on the rotating shaft 3. The primary branching wheel 42 and the secondary branching wheel 44 are fixedly sleeved on the connecting sleeve 41, with the primary branching wheel 42 located behind the secondary branching wheel 44. The diameter of the secondary branching wheel 44 is smaller than the diameter of the primary branching wheel 42. The primary branching wheel 42 can be fixedly connected to the mounting bracket 301. The branching half-hole 43 is opened around the outer perimeter of the primary branching wheel 42 and the secondary branching wheel 44, and corresponds to the limiting half-hole 202. The branching half-hole 43 of the primary branching wheel 42 can be combined with the limiting half-hole 202 to form a circular hole. A limiting protrusion 304 running from front to back is provided on the outer surface of the rotating shaft 3. A limiting groove 402 that mates with the limiting protrusion 304 is provided on the connecting bushing 41. The limiting protrusion 304 and the limiting groove 402 increase the fit between the rotating shaft 3 and the connecting bushing 41, while also restricting the movement direction of the connecting bushing 41, facilitating the corresponding connection between the primary branching wheel 42 and the mounting bracket 301. There are several secondary branching wheels 44, and the diameter of these secondary branching wheels decreases sequentially from back to front. The primary branching wheel 42 is connected to the mounting bracket 301 through these sequentially decreasing diameter secondary branching wheels. The wire separating wheel 44 smoothly reduces the distance between wires, preventing them from tangling. The inner side of the wire separating half-hole 43 is chamfered to reduce wire wear. A connecting bolt 401 is installed on the primary wire separating wheel 42, connecting to the connecting screw hole 302. A guide post 5 is located at the upper front end of the base 1, with a guide ring 501 at its upper end. The guide ring 501 is coaxial with the rotating shaft 3, and there is a space between them. The main wire and other wires are wound around this space. The wound cable is guided out through the guide ring 501 and supported by the base 1. The mounting hole 101 facilitates the installation of the base 1 onto an external space. The main cable to be wound passes through the inside of the rotating shaft 3. The connecting ear 303 facilitates the connection to the rotating shaft of the cable feeder, thereby driving the rotating shaft 3 to rotate synchronously. The wire to be wound is guided through the circular hole formed by the combination of the splitting half hole 43 and the limiting half hole 202. Its detachable design facilitates the placement of the wire into the corresponding circular hole. The splitting half hole 43 of the secondary splitting wheel 44 reduces the distance between each wire, thereby facilitating winding on the main cable.
[0018] The working principle of this utility model is as follows: An external bolt is passed through the mounting hole 101 to fix the base 1 in a suitable position. The rotating shaft 3 is connected to the rotating shaft of the cable feeder via the connecting ear 303 and the external bolt. The main cable passes through the front end of the rotating shaft 3. The connecting bolt 401 is unscrewed, and the primary cable feeder 42 is pulled. The limiting groove 402 slides along the limiting protrusion 304, separating the cable feeder half-hole 43 from the limiting half-hole 202. The cable from the cable feeder is passed through the mounting bracket 301 as needed and placed into the corresponding limiting half-hole 202. Then, the primary cable feeder 42 is pushed to engage the cable feeder half-hole 43 with the limiting half-hole 202, fixing the position of the cable. The connecting bolt 401 is tightened to fix the primary cable feeder 42. The passed cable is then passed through the cable feeder half-hole 43 of the secondary cable feeder 44 in sequence, and finally wound onto the main cable in the space between the rotating shaft 3 and the guide ring 501. The wound cable is then output from the guide ring 501.
