Description

Technical Field

[0001] This utility model belongs to the technical field of cradle rollers, and in particular, relates to a double-twisting cradle device. Background Technology

[0002] Cradle reels are a key piece of equipment used in the production of wires such as cables and wire ropes. Their core function is to achieve efficient winding and unwinding of wires, and their unique structural design ensures uniform tension and operational safety.

[0003] Chinese utility model patent CN222182904U discloses a quick locking device for the I-beam wheel of a steel cord twisting machine, including a rotating shaft. One end of the rotating shaft is coaxially provided with a locking shaft. The diameter of the locking shaft is smaller than the diameter of the rotating shaft, and an inner abutment is provided on it. The maximum diameter of the inner abutment is the same as the diameter of the rotating shaft, and both are supported from inside the wheel cylinder of the I-beam wheel. The end of the inner abutment away from the rotating shaft is provided with a first ring. The first ring is provided with a connector. One end of the connector is inserted into a pin hole on the wheel disc of the I-beam wheel. The end of the inner abutment away from the rotating shaft is provided with a limiting mechanism to restrict its axial movement on the locking shaft.

[0004] The aforementioned quick-locking device for the steel cord twisting machine's I-beam reel requires the operator to adjust the I-beam reel when it is installed on the rotating shaft. This adjustment ensures that the inner wall of the I-beam reel is flush with the outer wall of the rotating shaft before it moves axially along the shaft. During this process, the operator must repeatedly adjust the installation angle of the I-beam reel to ensure that its direction of movement during installation is consistent with the rotation axis of the rotating shaft. However, repeatedly adjusting the installation angle of the I-beam reel can easily cause impact damage to the I-beam reel and the rotating shaft, thus affecting their service life and increasing maintenance costs. Furthermore, the repeated adjustments also reduce the installation efficiency of the I-beam reel. Utility Model Content

[0005] Based on the aforementioned problems in the prior art, one of the objectives of this utility model embodiment is to provide a double twisting machine cradle device to solve the problems in the prior art where repeated angle adjustments during the installation of the I-beam wheel cause damage to the I-beam wheel, increasing maintenance costs and reducing installation efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A double-twisting machine cradle device is provided, comprising a frame and an installation mechanism located on the frame. The installation mechanism includes a support shaft, a brake disc rotatably sleeved on the support shaft, a guide nut, and a positioning component. One end of the support shaft is fixed to the frame, and the other end of the support shaft has an external thread. The brake disc is connected to an I-beam wheel and is used to make the I-beam wheel rotate with the brake disc. The guide nut is rotatably sleeved on the external thread on the support shaft. The positioning component is located at the end of the support shaft, and is connected to the guide nut and is used to position the guide nut. A guide surface is provided on the side of the guide nut away from the support shaft. The outer contour of the guide surface gradually decreases along the axial direction away from the support shaft. The guide surface is used for sliding connection with the inner wall of the I-beam wheel.

[0007] Furthermore, operating surfaces are provided on both side walls of the guide surface.

[0008] Furthermore, the guide nut has a fixed groove coaxially formed at one end away from the support shaft. The positioning element includes a screw and a washer. The screw is threaded through the fixed groove and then threadedly connected to the end of the support shaft. The washer is located in the fixed groove. One side of the washer is fitted onto the screw and abuts against the screw, while the other side of the washer is used to abut against the bottom of the fixed groove.

[0009] Furthermore, the positioning component also includes an abutment nut located on the side of the guide nut near the support shaft, wherein the inner sidewall of the abutment nut is threaded onto the external thread on the support shaft.

[0010] Furthermore, a plurality of bearings are provided on the outer side wall of the support shaft, the inner side wall of each bearing is connected to the outer side wall of the support shaft, and the outer side wall of each bearing is connected to the inner wall of the brake disc.

[0011] Furthermore, a first spacer and a second spacer are fitted on the outer side wall of the support shaft. The first spacer is located between several bearings. The two ends of the first spacer are used to abut against the bearings. There is a gap between the first spacer and the inner wall of the brake disc. One end of the second spacer abuts against the bearing, and the other end of the second spacer abuts against the side wall of the abutment nut. There is a gap between the second spacer and the inner wall of the brake disc.

[0012] Furthermore, the brake disc is provided with a pin for engaging with a pin hole on the side wall of the I-beam wheel.

[0013] Furthermore, a retaining circlip is provided on the side of the brake disc near the guide nut. The retaining circlip slides through the brake disc and is used to abut against the I-beam wheel.

[0014] Furthermore, a spring ring is provided on the outer wall of the brake disc, the spring ring is located on the side of the fixed snap ring, and the outer wall of the spring ring is used to abut against the inner wall of the H-beam wheel.

[0015] Compared with the prior art, one or more technical solutions in the embodiments of this utility model have at least one of the following beneficial effects: In this embodiment of the utility model, a cradle device for a double twisting machine has a positioning component that positions a guide nut on a support shaft, improving the stability of the guide nut. When the I-beam is installed on the frame, the operator first moves the I-beam to a set height via an installation mechanism on the frame, and then moves it to the guide nut. The guide surface on the guide nut contacts the inner wall of the I-beam, guiding it so that the I-beam moves along the rotation axis of the support shaft until it is transferred to a set position on the brake disc. This eliminates the need for the operator to repeatedly adjust the installation angle of the I-beam, reducing the risk of collision damage between the I-beam and the support shaft during transmission, extending the service life of the I-beam and the support shaft, and reducing maintenance costs. Furthermore, the elimination of the need for repeated adjustments to the installation angle of the I-beam facilitates installation and improves installation efficiency. Attached Figure Description

[0025] Please refer to the following: Figures 1 to 6 The present invention provides a cradle device for a double twisting machine. The cradle device for a double twisting machine includes a frame 2 and a mounting mechanism located on the frame 2. The mounting mechanism includes a support shaft 31, a brake disc 32, a guide nut 4, and a positioning element 5. One end of the horizontally arranged support shaft 31 is fixed to the frame 2, and the other end of the support shaft 31 has an external thread.

[0026] The brake disc 32 is T-shaped and rotatably mounted on the support shaft 31. A spring ring 33, a detent pin 8, and a retaining circlip 9 are provided on the outer wall of the brake disc 32. The spring ring 33 abuts against the inner wall of the I-beam wheel 1, allowing the I-beam wheel 1 to move onto the spring ring 33 on the brake disc 32, preventing it from moving arbitrarily along the axial direction of the support shaft 31. One end of the detent pin 8 is connected to the brake disc 32, and the other end is inserted into the side wall of the detent pin hole 11 on the I-beam wheel 1. The end of the retaining circlip 9 passes through the side of the brake disc 32 away from the support shaft 31 and is connected to the brake disc 32. The retaining circlip 9 supports the I-beam wheel 1 and abuts against the side wall of the I-beam wheel 1. The brake disc 32 houses several bearings 71, a first spacer 72, and a second spacer 73. Specifically, there are three bearings 71, divided into two groups: one group with two bearings 71 and the other with one bearing 71. The two bearings 71 are located at the end of the support shaft 31 near the mounting bracket, and the one bearing 71 is located at the end of the support shaft 31 away from the mounting bracket. The inner wall of each bearing 71 is fixed to the outer wall of the support shaft 31, and the outer wall of each bearing 71 is fixed to the inner wall of the brake disc 32, thereby allowing the brake disc 32 to rotate relative to the support shaft 31. The first spacer 72 is located in the gap between the two bearings 71 and the one bearing 71. The inner wall of the first spacer 72 is fixed to the outer wall of the support shaft 31, and there is a gap between the outer wall of the first spacer 72 and the inner wall of the brake disc 32. Both ends of the first spacer 72 abut against the bearings 71. The second spacer 73 is located between a bearing 71 and an abutment nut 53. The inner wall of the second spacer 73 is fixed to the outer wall of the support shaft 31. There is a gap between the outer wall of the second spacer 73 and the brake disc 32. One end of the second spacer 73 abuts against the bearing 71, and the other end of the second spacer 73 abuts against the abutment nut 53.

[0027] The guide nut 4 is located at the end of the support shaft 31 away from the frame 2, and the guide nut 4 is rotatably sleeved on the external thread on the support shaft 31. The outer side wall of the guide nut 4 is provided with a guide surface 41 for sliding connection with the inner wall of the I-beam wheel 1. The outer contour of the guide surface 41 gradually decreases along the axial direction away from the support shaft 31. Specifically, the guide surface 41 makes the guide nut 4 chamfered at a 50° acute angle, so that when the worker installs the I-beam wheel 1, the side wall of the guide nut 4 slides in contact with the inner side wall of the I-beam wheel 1, guiding the I-beam wheel 1, so that the I-beam wheel 1 moves along the rotation axis of the support shaft 31. This eliminates the need for the worker to adjust the installation angle of the I-beam wheel 1 multiple times, which would cause collision damage between the I-beam wheel 1 and the support shaft 31, reducing maintenance costs, facilitating installation, and improving installation efficiency. An operating surface 42 is provided on the side wall of the guide surface 41, which is convenient for workers to hold and install. A fixing groove 61 is coaxially provided on the side of the guide nut 4 away from the support shaft 31. The positioning component 5 includes a screw 51, a washer 52 and an abutment nut 53. The horizontally arranged screw 51 is coaxially arranged with the support shaft 31. One end of the screw 51 is located in the fixing groove 61, and the other end of the screw 51 passes through the fixing groove 61 and extends into the support shaft 31 and is threadedly connected to the end of the support shaft 31. The vertically arranged washer 52 is sleeved on the screw 51. One side of the washer 52 abuts against the screw 51, and the other side of the washer 52 abuts against the bottom of the fixing groove 61. The abutment nut 53 is located on the side of the guide nut 4 near the support shaft 31. The inner side wall of the abutment nut 53 is threaded onto the external thread on the support shaft 31, and the end of the abutment nut 53 abuts against the end of the guide nut 4.

[0028] The working principle of this utility model is as follows: When the worker installs the I-beam wheel 1 on the support shaft 31, the inner wall of the I-beam wheel 1 contacts the guide surface 41 on the guide nut 4, thereby guiding the I-beam wheel 1. This eliminates the need for the worker to repeatedly adjust the installation angle of the I-beam wheel 1, making it less likely for the I-beam wheel 1 to collide and be damaged with the support shaft 31, reducing maintenance costs, facilitating installation, saving working time, and improving installation efficiency.

[0029] Furthermore, when the I-beam 1 moves onto the brake disc 32, the retaining spring 9 abuts against the inner wall of the I-beam 1, thereby supporting the I-beam 1. At the same time, the spring ring 33 prevents the I-beam 1 from moving freely on the brake disc 32. When the I-beam 1 moves to the set position, the operator adjusts the detent 8 so that the detent 8 is inserted into the detent hole 11 on the side wall of the I-beam 1, thereby locking the I-beam 1 and making the I-beam 1 rotate with the brake disc 32, which facilitates the operation of the I-beam 1.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
