Description

Technical Field

[0001] This utility model belongs to the field of cable production equipment, and in particular relates to an adjustable core-setting device for cable armoring. Background Technology

[0002] Armored cables are special cables designed to enhance mechanical protection and resistance to external environmental damage. Their core feature is the addition of a metal protective layer to the outer layer of the cable. Armored cables increase the mechanical strength of the cable and improve its corrosion resistance through the metal protective layer. They are mainly designed for wires and cables in areas that are susceptible to mechanical damage and corrosion.

[0003] In the existing armoring process of armored cables, since the cable is basically formed and usually wound on a cable reel, it needs to be straightened before armoring can proceed. The existing armored cable straightening and core-setting device mainly uses upper and lower concave wheels to straighten and core the cable to be armored. Although the above structure can meet the straightening and core-setting of the cable to be armored, since the groove size of the concave wheels is the same, different concave wheels need to be replaced and the distance between the two upper and lower concave wheels needs to be adjusted for different specifications of the cable to be armored.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1, such as Figure 1 , Figure 2 As shown, this embodiment aims to address the technical problems existing in the current fixed straightening and core-setting devices by providing an adjustable core-setting device capable of accommodating different specifications. Therefore, the cable armored adjustable core-setting device provided in this embodiment includes a frame 1. In this embodiment, the frame 1 includes a fixing plate for fixing to the ground or platform and a vertical plate set on the fixing plate. For straightening and core-setting, a straightening wheel 11 is an essential accessory. Therefore, a straightening wheel 11 is provided on the frame 1. The straightening wheel 11 is rotatably mounted on the frame 1. It should be noted in this embodiment that "rotatable" refers to the fact that a rotating shaft is fitted at the center of the accessory. The accessory and the rotating shaft are connected by a bearing, or the rotating shaft and the frame 1 are connected by a bearing, enabling the accessory to rotate. The power required for its rotation mainly comes from the friction between the cable and the accessory during traction; that is, it is stationary when there is no cable traction.

[0017] Of course, in this embodiment, the straightening wheel 11 is also a concave wheel. To cooperate with the use of the straightening wheel 11 and to achieve straightening and core setting for cables of different specifications, an auxiliary straightening wheel 12 is also provided on the frame 1. The auxiliary straightening wheel 12 can extend into the groove of the straightening wheel 11. That is, the auxiliary straightening wheel 12 is a common disc structure without grooves on its side wall. In this way, the straightening of cables of different specifications can be achieved by changing the depth of its insertion into the groove of the straightening wheel 11. Since it is necessary to control the insertion depth of the auxiliary straightening wheel 12, the auxiliary straightening wheel 12 can be raised and lowered on the frame 1. Of course, the auxiliary straightening wheel 12 can also be rotatably mounted on the frame 1.

[0018] Considering that the straightening and centering method of the straightening wheel 11 and the auxiliary straightening wheel 12 is achieved by reducing the distance between the straightening wheel 11 and the auxiliary straightening wheel 12, but it cannot reduce the width of the groove of the straightening wheel 11, this may cause the cable to deviate during the traction process, thus affecting the straightening effect. Therefore, an auxiliary straightening mechanism 2 is also provided on the frame 1. Specifically, the auxiliary straightening mechanism 2 includes a straightening plate 21 set at the feeding end of the straightening wheel 11. The straightening plate 21 includes an upper straightening plate 21 and a lower straightening plate 21 set vertically, both of which are rectangular in shape. Arc-shaped grooves are provided on the opposite surfaces of the upper and lower straightening plates 21. Simultaneously, the ends of the upper and lower straightening plates 21 near the straightening wheel 11 are axially connected to the frame 1. Thus, the upper and lower straightening plates 21 can... The device can be flipped by one end of the shaft connection. At the same time, a connecting rod 22 is ball-jointed on the top surface of the upper straight plate 21 and the lower straight plate 21 at the end away from the straightening wheel 11. An eccentric turntable 23 is shaft-connected to the end of the connecting rod 22 away from the upper straight plate 21 and the lower straight plate 21. A drive motor 24 for driving the eccentric turntable 23 to rotate is provided on the frame 1. The eccentric turntable 23 referred to in this embodiment is generally arranged in a disc shape. The output end of the drive motor 24 is connected at the center of the eccentric turntable 23, while the shaft connection of the connecting rod 22 is not at the center.

[0019] In this way, under the action of the drive motor 24, the ends of the upper straightening plate 21 and the lower straightening plate 21 away from the straightening wheel 11 repeatedly close and open, forming a preliminary straightening and limiting of the cable, ensuring that the cable does not deviate.

[0020] In order to achieve the lifting and lowering of the auxiliary straightening wheel 12, a gantry-shaped adjustment seat 3 is provided on the frame 1, and a lifting cylinder 4 is provided on the top of the gantry-shaped adjustment seat 3. The power end of the lifting cylinder 4 is set downward, and the power end of the lifting cylinder 4 is connected to an adjustment block 5. The auxiliary straightening wheel 12 is rotatably mounted on the adjustment block 5. In this way, the adjustment block 5 is slidably mounted on the gantry-shaped adjustment seat 3 by the action of the lifting cylinder 4.

[0021] To further prevent cable deviation, guide rollers are provided on both sides of the straightening wheel 11. The guide rollers include an upper guide roller 6 and a lower guide roller 7, which are rotatably mounted on the frame 1. The top surface of the lower guide roller 7 is flush with the bottom surface of the groove of the straightening wheel 11, while the bottom surface of the upper guide roller 6 contacts the maximum diameter of the cable allowed by the groove of the straightening wheel 11. This arrangement mainly uses the lower guide roller 7 to maintain the horizontal input and output of the straightening wheel 11 and prevent deviation. At the same time, the upper guide roller 6 provides a certain degree of limitation to solve the problem that the auxiliary straightening wheel 12, being a flat wheel, lacks the restraint for large-diameter cables.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
