Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a stranding frame for a cantilever single twister used in cable production. Background Technology

[0002] Cable production utilizes a single-strand twister to twist multiple strands of cable together. The twisting frame is equipped with twisting wheels, and the appropriate size of the twisting wheel needs to be changed depending on the winding material. The counterweight on the twisting machine must be aligned with the twisting wheel. However, in existing technology, the counterweight and twisting wheel are fixed to the cantilever with bolts. When the bolts loosen, the high-speed rotating twisting wheel and counterweight will vibrate, affecting performance.

[0003] To this end, Chinese Patent Application No. 202010208299.5 discloses a stranding frame for a cantilever single twister, which involves threading a mounting base to the wall of a mounting groove. During the threaded connection, the movable seat contacts the contact plate. As the mounting base rotates continuously, the first elastic element gradually becomes contracted. With the movement of the mounting base, the movable seat pushes the contact plate and the first piston toward the first oil chamber. The hydraulic oil in the first oil chamber is squeezed into the second oil chamber through the oil pipe. When the mounting base contacts the first cantilever, the hydraulic oil squeezes out the second piston in the second oil chamber, and the push rod extends out of the second oil chamber. At the same time, the second elastic element remains in a stretched state. The push rod and the limiting ring outside the movable seat form a limiting structure, and the mounting base is stably installed.

[0004] Although this structure can help with quick positioning and installation between the mounting base and the cantilever, the limiting structure will automatically loosen when the mounting base rotates in the opposite direction relative to the cantilever because the mounting base is screwed onto the cantilever by rotation. During the high-speed rotation of the stranding frame, the mounting base is prone to reverse rotation relative to the cantilever under the action of centrifugal force, which will cause the connection between the mounting base and the cantilever to loosen. Therefore, the entire connection structure has insufficient safety and stability.

[0005] To address this issue, we propose a stranding frame for a cantilever single-strand cable production machine. Utility Model Content

[0006] In order to solve the above-mentioned problems, this utility model designs a stranding frame for a cantilever single twister used in cable production.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A stranding frame for a cantilever single stranding machine used in cable production includes a stranding frame, a fixing plate on the right end wall of the stranding frame, a connecting seat on the right side wall of the fixing plate, and elongated holes through the upper and lower end faces of the outer wall of the connecting seat.

[0009] It also includes a reel, a mounting base is provided on the left end wall of the reel, a baffle is provided on the left end wall of the mounting base, a socket is provided on the left end wall of the baffle, sliders are provided at both the upper and lower ends of the outer wall of the socket, and a fixed seat is movably sleeved on the outer wall of the mounting base.

[0010] Furthermore, the outer wall of the connector is provided with external threads.

[0011] Furthermore, the inner wall of the fixing seat is provided with an internal thread, which is threadedly matched with the connecting seat.

[0012] Furthermore, the outer circumference of the fixing base is provided with multiple protrusions at equal intervals.

[0013] The beneficial effects of this utility model are:

[0014] This utility model adopts a completely new connection method, abandoning the method in the prior art that relies solely on threaded connections and is prone to loosening due to reverse rotation. By welding the fixing plate to the stranding frame and the mounting base to the spool, and then utilizing the limiting fit between the slider and the elongated hole, as well as the fastening of the fixing base, the connection between the spool and the stranding frame is made more stable. During the high-speed rotation of the stranding frame, it can effectively prevent the connection from loosening due to the centrifugal force causing the mounting base to reverse relative to the cantilever. This greatly improves the safety and stability of the entire connection structure and reduces the risk of safety accidents that may be caused by loose connections. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-3 As shown, a stranding frame for a cantilever single stranding machine for cable production includes a stranding frame 1, a fixing plate 2 is provided on the right end wall of the stranding frame 1, a connecting seat 3 is provided on the right side wall of the fixing plate 2, and elongated holes 4 are provided through the upper and lower end faces of the outer wall of the connecting seat 3.

[0023] It also includes a reel 5, a mounting base 6 on the left end wall of the reel 5, a baffle 7 on the left end wall of the mounting base 6, a socket 8 on the left end wall of the baffle 7, sliders 9 on both the upper and lower ends of the outer wall of the socket 8, and a fixed base 10 movably sleeved on the outer wall of the mounting base 6.

[0024] Furthermore, the outer wall of the connector 3 is provided with external threads. The socket 8 is inserted into the connector 3 along with the slider 9, and the slider 9 is slid into the elongated hole 4. The slider 9 limits the socket 8, preventing it from rotating inside the connector 3. The fixing seat 10 is rotated to the outer wall of the connector 3 and abuts against the outer wall of the fixing plate 2. The socket 8 is installed inside the connector 3, thereby installing the wire wheel 5 on the right side wall of the stranding frame 1.

[0025] Furthermore, the inner wall of the fixing seat 10 is provided with an internal thread, which is threadedly matched with the connecting seat 3. By rotating the fixing seat 10, the fixing seat 10 is unscrewed from the outer wall of the connecting seat 3. The wire wheel 5 is pulled to the right, causing the mounting seat 6 to move the baffle 7, socket 8 and slider 9 to the right in the connecting seat 3 and the elongated hole 4, and then remove them. The wire wheel 5 is then removed from the stranding frame 1.

[0026] Furthermore, multiple protrusions 11 are provided at equal intervals on the outer circumference of the fixing base 10 to facilitate the user to rotate the fixing base 10.

[0027] The detailed connection methods are well-known technologies in the field. All components in this solution are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0028] One specific application of this embodiment is:

[0029] The first step is the fixing and installation of the components. The fixing plate 2 is firmly installed on the right side wall of the strand frame 1 by welding. This welding process ensures that a strong connection is formed between the fixing plate 2 and the strand frame 1, so that it can withstand the corresponding force during subsequent high-speed operation and is not prone to loosening or displacement. Similarly, the mounting base 6 is also installed on the left side wall of the reel 5 by welding. This welding method ensures a tight connection between the mounting base 6 and the reel 5, providing a stable foundation for subsequent installation and use.

[0030] Next is the installation process of the reel 5. During installation, the socket 8 is inserted into the connector 3 with the slider 9. The design of the slider 9 plays a key limiting role. When it slides along the track of the connector 3 and into the inlet hole 4, it restricts the rotation of the socket 8 in the connector 3. This limiting design ensures the positional stability of the socket 8 and avoids inaccurate installation caused by the random rotation of the socket 8 during the installation process. Then, the fixing seat 10 is rotated clockwise so that it gradually approaches the outer wall of the connector 3. During the rotation, the operator needs to pay close attention to the position of the fixing seat 10. When the fixing seat 10 is tightly fitted with the outer wall of the connector 3 and abuts against the outer wall of the fixing plate 2, the socket 8 is then firmly installed in the connector 3, thus successfully installing the reel 5 on the right side wall of the stranding frame 1. This series of operation steps are closely linked to ensure the accuracy and stability of the reel 5 installation.

[0031] When it is necessary to disassemble the spool 5, the operation steps are relatively simple and orderly. First, rotate the fixing seat 10 counterclockwise to gradually unscrew it from the outer wall of the connecting seat 3. During the rotation, pay attention to the control of the force to ensure that the fixing seat 10 can smoothly detach from the outer wall of the connecting seat 3. After the fixing seat 10 is completely unscrewed, slowly pull the spool 5 to the right. Since the mounting seat 6 is welded to the spool 5, the mounting seat 6 will move together with the spool 5, thereby driving the connected baffle 7, socket 8, and slider 9 to move to the right within the connecting seat 3 and the elongated hole 4. As the spool 5 is continuously pulled, the baffle 7, socket 8, and slider 9 gradually move out of the connecting seat 3 and the elongated hole 4, and finally the spool 5 is successfully removed from the stranding frame 1.

[0032] Through the above detailed and standardized installation and disassembly steps, not only is the stable installation and reliable use of the upper winding wheel 5 of the cantilever single twister stranding frame guaranteed, but it also provides convenience for equipment maintenance and component replacement in the cable production process, improving production efficiency and the overall operational stability of the equipment.

[0033] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
