Description

Wrapping device of inner shield longitudinal wrapping machine

technical field

The invention relates to a wrapping device of an inner shielding longitudinal wrapping machine, which is used for wrapping a polyester film wrapping tape outside a longitudinally wrapped copper strip of a four-wire group to form a wire group shield, and belongs to the technical field of cable processing equipment.

Background technique

In the wire and cable processing industry, for example, four insulated core wires (usually made of copper) are first twisted into a four-wire group, and then the copper tape is longitudinally wrapped around the four-wire group, and then the polyester tape is wrapped around the longitudinally wrapped copper tape. The film tape (also known as polyester wrapping tape) is used to form the shield, that is, the inner shield, but enters the cable. Cabling is to twist a plurality of four-wire groups that have formed the inner shield to form a cable core, and then process the cable core according to different purposes, such as the structure shown in Chinese patent ZL200410014668.8 outside the cable core Set the inner lining layer, aluminum sheath, inner sheath, armor layer, outer sheath, etc. in sequence.

At present, the outer wrapping polyester film wrapping tape of the copper strip that constitutes the four-wire group is completed through the wrapping device of the inner shielding longitudinal wrapping machine. The specific structure is shown in Figure 3, including frame 1, installed on the machine The motor 2 on the frame 1, the groove shaft 3 with the belt winding groove 34, the hollow shaft 3 that is connected by the small pulley 21 through the belt 211 and the pulley 32 that is pivotally placed on the frame 1 by the bearing 331 on the bearing seat 33 The grooved disk 4 with the first and second tape guide rollers 41, 42 and a balance weight 43 sleeved on the grooved shaft 3, and the tape supply reel 9 set on the grooved shaft 3 through the sleeve 51 are seated The wrapping tape reel seat 5, the quick positioning collet 6 of the tool stop bar 61 that is located on the grooved shaft 3, when in use, first temporarily unload the quick positioning chuck 6, so that the wrapping tape reel 9 can be self-slotted. One end of the shaft 3 is moved to the wrapping tape reel seat 5, and one side of the wrapping tape reel 9 is leaned against the wrapping tape reel seat 5, then the quick positioning chuck 6 is fixed on the groove shaft 3, and the The other side of the tape reel 9 is limited by the supporting force of the spring 36 that is distributed around the tape reel seat 5, and the four-wire group 10 is introduced from one end of the hollow groove shaft 3 and pulled out from the other end. The wrapping tape drawn from the wrapping tape reel 9 is guided and limited by the first and second tape guide rollers 41, 42 and the limit rod 61, and then leads to the tape groove 34 of the groove shaft 3 and reaches the fourth line. Group 10. Along with the work of motor 2, the grooved shaft 3 is driven to rotate by the belt 211 through the pulley 32 fixed on the grooved shaft 3, and the grooved shaft disc 4 rotates with it. The wrapping tape is longitudinally wrapped on the quad 10 so that the quad 10 constitutes an inner shield.

Since the structure and working principle of the wrapping device of the above-mentioned inner shielding longitudinal wrapping machine are relatively simple, it is widely used in the cable processing industry. But also there is following deficiency: the one, because the position-limiting to wrapping reel 9 is to take on by spring 36, so after using for a period of time, the action effect of spring 36 weakens very quickly, can't play a role in winding wrapping. The limit of the tape reel 9 makes the wrapping tape reel 9 free from the wrapping tape reel seat 5 and causes the phenomenon of flying discs. The four-wire group 10 cannot obtain the longitudinal wrapping according to the process requirements, even if the motor 2 is stopped working and the power that pulls the four-wire group 10 to advance is stopped in time, and the wrapping tape reel 9 is reinstalled, but objectively in the four-wire group 10 The unpacked part has been left on the line group 10, and tedious rework must be carried out; second, in order to detect the flying disc early and dispose of the flying disc very quickly, the workers must always pay attention to the working dynamics of the vertical charter machine, so that the workers are always under high mental tension The third is that once there is a flying disc, the wrapping tape that is unwound on the wrapping tape reel 9 will be formed into a messy tape and cause waste, because the chaotic tape that has to be unwound must be cut off, and if in order to avoid waste, it will be deliberately It will take considerable energy and time to straighten out the chaotic bands that are unwound, which will affect the production schedule; the fourth is that due to the long length of the four-wire group 10, it is impossible to use a four-wire group 10 from the starting point to the end point. To complete the longitudinal wrapping of the wrapping tape on the wrapping tape reel 9, it is often necessary to complete the longitudinal wrapping of a four-wire group 10 from the starting point to the end point by wrapping tapes on a plurality of wrapping tape reels 9. In the prior art, it is Pre-set several wrapping tape reels directly on the slotted shaft 3 as a backup, thus occupying the limited space of the slotted shaft 3 unreasonably, especially when the slotted shaft 3 rotates, the wrapped tape reels attached to the slotted shaft 3 9 There will be chattering, mutual friction and collision, which will damage the wrapping tape.

Detailed ways

In Fig. 1, the base frame 1 is preferably a box-like structure, the motor 2 is fixed on the bottom of the box, the output shaft of the motor 2 is fixed with a small pulley 21, and an end of a belt 211 is sleeved on the small pulley 21, and the belt The other end of 211 is sleeved on the belt pulley 32 fixed on the right end of the grooved shaft 3 (taking the position shown in the figure as an example). The tail portion of the right end of the grooved shaft 3, that is, the base, is pivoted on the shaft seat 31, and the grooved shaft 3 is pivoted with the box wall of the frame 1 through the bearing 331 arranged on the bearing seat 33 at a position close to the grooved shaft disk 4. place. The grooved shaft disk 4 is fixed on the grooved shaft 3, and the first and second belt guide rollers 41, 42 and a balance weight 43 are fixedly installed on the disk surface of the grooved shaft disk 4 one side. 1. The second belt guide rollers 41, 42 are separated by 180°. The cross-sectional shape of the wrapping tape reel seat 5 is a horizontally placed convex shape, and the convex tube end part is called the base of the wrapping tape reel seat 5, which is used to seat or nest the winding shown by the dotted line in the figure. Tape reel 9, and the expansion part of convex character is called disc surface 52. As can be seen from the figure, an expanded diameter is attached to the disk surface 52 by a fixing screw, that is, a relying disk 521 whose diameter is larger than the disk surface 52, when the wrapping reel 9 is placed on the base of the wrapping reel seat 5 , the side portion of the entire wrapping tape reel 9 can be well attached to the backing plate 521 .

The contribution of the present invention is to process a threaded segment 35 with several turns of thread 351 on the grooved shaft 3 close to the base of the wrapping tape reel seat 5 , and a cotter nut 7 with threads 71 is arranged on the threaded segment 35 . Thus, due to the effect of the split nut 7, the wrapping reel 9 placed on the base of the wrapping reel seat 5 can be clamped and limited, and the wrapping reel 9 will never appear to be out of the wrapping during the working process. The base of the reel seat 5 comes out. The main function of the quick positioning chuck 6 that is arranged on the grooved shaft 3 and is extended with a limit rod 61 is to guide the wrapping tape drawn from the wrapping tape reel 9 . The process of guiding the tape drawn out from the tape reel 9 can be understood by referring to FIG. 2 , which will be described below.

In order to meet the longitudinal wrapping of a quartet 10 of sufficient length (generally hundreds of meters), it is necessary to take on the role of many coils of wrapping reels 9. ) is equipped with a bracket 8, a tube 81 is extended on the bracket 8 in a vertical direction with the bracket, and the seat tube hole 811 of the seat tube 81 is used for the four-wire group after completing the polyester film band after the longitudinal wrapping 10 is passed, and the seat tube 81 is provided with multi-coil wrapping reels 9, five reels are shown in the figure, but they are not unique. The amount of attachment depends on many factors, such as the length and winding The number of meters of the wrapping tape on the tape reel 9 or the like.

In Fig. 2, the applicant has given another situation of the threaded section 35 on the grooved shaft 3, that is, the span of the threaded section 35 is expanded, and the distance of the threaded section 35 is extended, so that the spring 20 and the spring seat are placed 30, the spring 20 acts on the cotter nut 7 to prevent the cotter nut 7 from retreating. The rest are the same as the description of Figure 1.

Of course, if the cotter nut 7 of the structure shown in Fig. 1 is configured with a set screw for being screwed onto the shaft body of the grooved shaft 3, the loosening of the cotter nut 7 can also be prevented, specifically, when the cotter nut After 7 is screwed in place, tighten the screw with a screwdriver, otherwise, unscrew the screw first, and then unscrew the port nut 7.

The applicant briefly describes the working principle of the present invention in conjunction with Fig. 1, firstly separates the quick positioning collet 6 from the grooved shaft 3, and removes the cotter nut 7 from the grooved shaft 3, and then sets the wrapping tape reel 9 on the winding shaft Tape the base of the reel seat 5, and then screw the cotter nut 7 onto the threaded section 35, and the cotter nut 7 will block the tape reel 9, and fix the previously removed quick positioning collet 6 to the grooved shaft 3 . Lead out the end of the wrapping tape whose material is polyester from the wrapping tape reel 9, wrap around the first and second tape guide rollers 41, 42, and the stop bar 61 in sequence, and then align it with the tape take-up groove on the groove shaft 3 34, until the quadruple group 10 leading to the through hole going to the grooved shaft 3. Starter motor 2 works, and slot shaft 3 rotates, and slot shaft disc 4 also rotates with it. In the process, the wrapping tape withdrawn from the wrapping tape reel 9 is longitudinally wrapped on the four wire group 10. The speed at which the quadruple group 10 passes through the shaft hole of the grooved shaft 3 should be consistent with the working speed of the inner shielding longitudinal wrapping machine of the present invention. As the quadruple group 10 continues to advance, the continuous winding of the quadruple group 10 will be completed. longitudinal package. Before the wrapping tape on the wrapping tape reel 9 is almost used up and not exhausted, stop the machine, make the four-wire group 10 stop moving, and make the motor 2 stop working, then change the tape, loosen the split nut 7, and The core of the exhausted wrapping tape reel 9 is knocked off with a tool, the quick positioning chuck 6 is removed, and a coil of wrapping tape reel 9 is removed from the seat tube 81, and the wrapping tape and the four-wire group 10 are put on according to the aforementioned process. The end of the wrapping tape is bonded, tighten the cotter nut 7 and the quick positioning chuck 6 respectively, start the motor 2 and simultaneously start the power to make the four-wire group 10 advance, and carry out longitudinal wrapping. The four-wire group 10 after vertical wrapping enters into cable by the aforementioned cable-forming process.

Since the principle of FIG. 2 is similar to that of FIG. 1, the only difference is that the operation of the spring 30 needs to be added, so the applicant will not repeat the working principle.
