Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and more specifically, to a winding and knotting mechanism. Background Technology

[0002] In the production and processing of wires, cables, and optical fibers, winding equipment is a key piece of equipment for orderly winding cables onto spools (also known as bobbins). Its technological level directly impacts the quality of cable products, production efficiency, and subsequent application experience. From an industry process perspective, cable production encompasses upstream processes such as conductor drawing, insulation extrusion, cabling, and sheathing. The winding process is the core step in the standardized winding of the formed cable—by precisely controlling the cable's tension, arrangement accuracy, and winding density, it ensures the cable is wound into a regular shape onto the spool, laying the foundation for subsequent warehousing, transportation, and terminal installation.

[0003] However, the winding and knotting mechanism in traditional winding equipment has the following defects or shortcomings when in use:

[0004] 1) The winding assembly mostly adopts single-stage transmission or direct drive. During the power transmission process, speed fluctuations or insufficient torque are prone to occur, resulting in poor winding uniformity and insufficient rotational stability of the I-beam wheel.

[0005] 2) The cable cutting process often uses fixed cutters or manual operation, resulting in insufficient cutting position accuracy, severe burrs on the cut surface, and a high waste rate;

[0006] 3) The transmission system of the winding and knotting mechanism lacks coordinated control. The independent operation of each functional module is prone to interference, making equipment debugging and maintenance difficult and unable to meet the needs of large-scale production.

[0007] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0008] In view of the problems in the related technologies, this utility model proposes a winding and knotting mechanism to overcome the above-mentioned technical problems existing in the existing related technologies.

[0009] Therefore, the specific technical solution adopted by this utility model is as follows:

[0010] A winding and knotting mechanism includes: a winding assembly, mounted on an I-beam wheel mounting base, for winding cables;

[0011] A knotting assembly, located on one side of the winding assembly, is used to knot the cable.

[0012] The winding assembly includes a drive motor mounted on the top of the I-beam wheel fixing base. One end of the drive motor is provided with a drive wheel. A drive shaft is inserted inside the I-beam wheel fixing base. One end of the drive shaft is provided with a driven wheel. The driven wheel and the drive wheel are connected by a belt to drive the movable chuck to rotate and realize the winding of the I-beam wheel.

[0013] The knotting assembly includes a bushing installed on the end of the drive shaft away from the driven wheel, a knotting rotating seat is sleeved on the outer side of the bushing, and a knotting seat is sleeved on the outer side of the knotting rotating seat; a power device for driving the knotting rotating seat is provided on the I-beam wheel fixing seat.

[0014] The other end of the knotting rotating seat is provided with a turntable. The surface of the turntable is provided with a first wire clamping post and a second wire clamping and cutting post. On the surface of the turntable, a knotting post is provided on the side of the second wire clamping and cutting post away from the first wire clamping post. The end of the knotting post is movably provided with a cylinder-driven push plate to push out the cable wound around the front end of the knotting post. A third wire clamping post is provided on the surface of the turntable at the lower part of the knotting post.

[0015] As a preferred embodiment, a positioning plate is fitted on the outer side of the bushing, and a plurality of spring posts are provided on the surface of the positioning plate facing the turntable, with springs fitted on the outer side of the spring posts.

[0016] As a preferred embodiment, the first wire clamping post and the second wire clamping and cutting post are each connected to the turntable via a fixing plate, and the knotting post and the third wire clamping post are connected to the turntable via the same fixing plate.

[0017] As a preferred embodiment, a notch is provided on one side of the second wire clamping and cutting post, and a cylinder-driven shearing rod that cooperates with the notch is provided inside the second wire clamping and cutting post to cut the cable.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1) The knotting assembly of this utility model achieves precise rotation control of the turntable through the hierarchical transmission of the bushing, the knotting rotating seat and the turntable, combined with the meshing transmission of the driving gear and the driven gear of the knotting motor. With the ring layout of the first to the third wire clamping posts, a closed loop winding trajectory is formed. At the same time, the cylinder-driven straight push plate and shearing rod respectively achieve the precise push of the cable on the knotting post and the synchronous cutting at the notch, ensuring the high efficiency and reliability of knotting.

[0021] 2) The spring buffer structure between the positioning plate and the turntable of this utility model can adaptively adjust the tension during the clamping process, avoiding damage to the cable caused by rigid contact. Attached Figure Description

[0030] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0031] According to an embodiment of the present invention, a winding and knotting mechanism is provided.

[0032] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, the winding and knotting mechanism according to an embodiment of the present utility model includes a winding assembly 1, which is disposed on an I-beam wheel fixing seat and is used for winding a cable; and a knotting assembly 2, which is disposed on one side of the winding assembly 1 and is used for knotting the cable.

[0033] The winding assembly 1 includes a drive motor 101 mounted on the top of the I-beam reel fixing base. One end of the drive motor 101 has a drive wheel 102. A drive shaft 103 is inserted inside the I-beam reel fixing base. One end of the drive shaft 103 has a driven wheel 104, and the driven wheel 104 is connected to the drive wheel 102 via a belt 105 to drive the movable chuck to rotate, thus winding the I-beam reel. The diameter of the driven wheel 104 is larger than the diameter of the drive wheel 102.

[0034] The working principle of the winding assembly is as follows: the drive motor 101 drives the drive wheel 102, belt 105 and driven wheel 104 to rotate clockwise, which causes the driven wheel 104 to drive the drive shaft 103 to rotate clockwise, thereby causing the movable chuck to drive the I-beam wheel to rotate clockwise, and the winding operation of the cable can be completed by the rotation of the I-beam wheel.

[0035] In one embodiment, the knotting assembly 2 includes a bushing 201 mounted on the end of the drive shaft 103 away from the driven wheel 104. A knotting rotating seat 202 is fitted on the outer side of the bushing 201, and a knotting seat 203 is fitted on the outer side of the knotting rotating seat 202. One end of the knotting rotating seat 202 is connected to the driven gear 204, and the bottom of the driven gear 204 is provided with a drive gear 205 that meshes with it. A knotting motor 206 that cooperates with the drive gear 205 is provided on one side of the bottom of the I-beam wheel fixing seat. A turntable 207 is provided at the other end of the knotting rotating seat 202. A first wire clamping post 208 is provided on the top surface of the turntable 207. A second wire clamping and cutting post 209 is provided on one side of the first wire clamping post 208. A knotting post 210 is provided on the side of the second wire clamping and cutting post 209 away from the first wire clamping post 208. A third wire clamping post 211 that cooperates with the bottom of the knotting post 210 is provided. A positioning plate 212 is fitted on the outer side of the bushing 201. Several spring posts 213 are provided on the surface of the positioning plate 212 facing the turntable 207, and springs 214 are fitted on the outer side of each spring post 213. The first wire clamping post 208, the second wire clamping and cutting post 209, the knotting post 210, and the third wire clamping post 211 are all connected to the turntable 207 via a fixing plate 215. The knotting post 210 and the third wire clamping post 211 are connected to the turntable 207 via the same fixing plate 215. A notch 216 is provided on one side of the second wire clamping and cutting post 209, and a cylinder-driven shearing rod 217 that cooperates with the notch 216 is provided inside the second wire clamping and cutting post 209 to cut the cable. A cylinder-driven straight push plate 218 is movably provided at the end of the knotting post 210 to push out the cable wound around the knotting post 210.

[0036] The working principle of the knotting assembly is as follows: Before the knotting operation begins, the cable feeding section wound on the I-beam reel is located at the position corresponding to the gap between the knotting post 210 and the second wire clamping and cutting post 209.

[0037] After the winding is complete, turn off the drive motor 101 to stop the H-beam wheel from rotating. Then start the knotting motor 206, causing the drive gear 205 to drive the driven gear 204 to rotate counterclockwise, thereby causing the knotting rotating seat 202 and the wire threading wheel to rotate counterclockwise toward the turntable 207 (as in the following sequence). Figures 5-6 (as shown)

[0038] At this time, the straight push plate 218 in the knotting post 210 retracts first through the cylinder drive. After the front end of the knotting post 210 drives the cable to rotate counterclockwise once, the cabling device at the front of the equipment moves and places the cable it delivers on the side of the knotting post 210 away from the second wire clamping and cutting post 209. At the same time, the third wire clamping post 211 clamps the part of the cable wrapped around it (as in...). Figures 7-8 (as shown)

[0039] Then, the knotting motor 206 drives the wiring wheel to move clockwise toward the turntable 207, causing the cable to wrap sequentially around the notch 216 of the second clamping and cutting post 209 and the first clamping post 208. The first clamping post 208 then clamps the cable, and subsequently, the cylinder drives the shearing rod 217 to retract, completing the cable cutting process (as in the sequence). Figures 8-9 - Figure 10 (as shown)

[0040] The straight push plate 218 pushes the cable wound on the knotting post 210 out, and at the same time, the drive motor 101 is started again to drive the I-beam wheel to rotate clockwise. Since the third clamping post 211 clamps the tail of the cut cable, the cable tail is pressed into the winding on the I-beam wheel (i.e., knotting operation). Finally, the knotting motor 206 controls the wiring wheel to turn to the turntable 207 to reset the knotting post 210, the first clamping post 208, the second clamping and cutting post 209, and the third clamping post 211.
