Description

TECHNICAL FIELD

[0001] The utility model belongs to non-standard equipment technical field, especially point to a kind of sleeve device of automatic processing equipment of electric wire. BACKGROUND

[0002] In industrial production, the connection between the electric wire and the terminal is a crucial link. In the processing process, the insulating layer of the electric wire must be removed first to facilitate effective connection with the terminal and realize electrical splicing. In addition, in order to facilitate the differentiation of phase sequence and other information, the end of the electric wire usually needs to be sleeved with a sleeve of a specific color, and sometimes a heat-shrinkable sleeve is used.

[0003] In the existing technical practice, when the sleeve is flat, it is difficult to expand the sleeve using mechanical clamps, clamps and other devices, so it cannot be accurately sleeved on the electric wire, which seriously affects the efficiency and quality of the sleeve. The current solution is to first deform the sleeve by manual extrusion to form a crease, and then input the sleeve into the machine. Although this can solve the problem to some extent, it consumes a large amount of labor cost and time cost, and the efficiency and quality are low. SUMMARY

[0004] The main purpose of the utility model is to provide a sleeve device for automatic processing equipment of electric wire, which solves the problems in the prior art and is suitable for the sleeving operation of flat sleeves on the end of the electric wire.

[0005] To achieve the above purpose, the solution of the utility model is as follows:

[0006] A sleeve device for automatic processing equipment of electric wire, comprising a sleeve conveying mechanism, a sleeve expanding mechanism and a mounting bracket, and at least one tray rotatingly fitted on the mounting bracket, the tray being wound with flat sleeves; the sleeve conveying mechanism conveys the sleeves to the sleeve expanding mechanism and cuts off the sleeves according to the set length; the sleeve expanding mechanism expands the sleeves cut off by the sleeve conveying mechanism and sleeves the periphery of the electric wire; the sleeve conveying mechanism comprises guide rollers, extrusion shafts, guide blocks, pipe feeding shaft assemblies and pipe cutting knives arranged in sequence along the sleeve conveying direction; the guide rollers are arranged horizontally and have two upper and lower guide rollers, and a gap is reserved between the two guide rollers for the sleeves to pass through; the extrusion shafts are arranged vertically and at least one pair of extrusion shafts are arranged on both sides of the sleeves, and the diameter of the extrusion shafts gradually increases from the middle position to the upper and lower ends; the distance between the middle positions of the extrusion shafts adjacent to each other is less than the width of the sleeve; the guide block is provided with a channel matched with the flat sleeve; the pipe feeding shaft assembly is used to provide power to forwardly convey the sleeve; and the pipe cutting knife is used to cut off the sleeve.

[0007] The pipe feeding shaft assembly comprises at least one pair of upper and lower parallel pipe feeding rubber rollers, and the driving roller in the pipe feeding rubber roller is driven by a pipe feeding motor.

[0008] Preferably, the sleeve conveying mechanism further comprises a guide roller support for mounting the guide roller, a pipe extruding shaft support for mounting the pipe extruding shaft, a pipe cutting support for mounting the guide block and the pipe cutting knife; the pipe extruding shaft support is provided with an adjusting sliding groove, the bottom of the pipe extruding shaft is provided with a pipe extruding shaft mounting plate which is adjustably mounted in the adjusting sliding groove, and a bearing is further arranged between the pipe extruding shaft and the pipe extruding shaft mounting plate; the channel is a groove arranged at the bottom of the guide block, and the guide block is fixed on the pipe cutting support by a pressing block.

[0009] Preferably, the pipe cutting support is provided with a cutting knife guide rail, and a pipe cutting cylinder for driving the pipe cutting knife is arranged above the cutting knife guide rail.

[0010] Preferably, the driving roller in the pipe conveying rubber roller is arranged at the lower position, the driven roller is arranged at the upper position and is mounted on a moving support, the moving support is provided with a lifting cylinder for driving the lifting support, and the driven roller is mounted on the lifting plate.

[0011] Preferably, the driven roller is shorter than the driving roller, the moving support is driven by a horizontal moving cylinder mounted on the pipe cutting support, and the pipe extruding shaft, the guide block and the tray are provided with two groups of left and right groups, and the driven roller is adjusted to be opposite to one guide block under the driving of the horizontal moving cylinder.

[0012] The sleeve expanding mechanism comprises a bottom plate, a moving plate slidingly fitted on the bottom plate, an expanding support mounted on the moving plate, left and right gas claws arranged at the input direction of the expanding support, a guide plate arranged at the output direction of the expanding support, a pair of guide plates arranged in parallel at the upper and lower positions of the guide plate and capable of being opened and closed, and a guide slope arranged at the opening of the guide plate.

[0013] Preferably, the moving plate is driven by an expanding motor arranged on the bottom plate.

[0014] Preferably, the guide plate is driven by a guide opening and closing cylinder.

[0015] Preferably, the expanding support is slidingly fitted on the moving plate along a direction perpendicular to the pipe conveying direction and is driven by an expanding horizontal moving cylinder.

[0016] After the above technical scheme is adopted, the sleeve expanding mechanism has the following technical effects:

[0017] This invention features at least one pair of extrusion shafts on both sides of the sleeve. The upper and lower sections of each extrusion shaft are conical, with the middle section being the narrowest and the ends the widest. This creates an approximately rhomboid sleeve channel between adjacent extrusion shafts. Because the distance between the middle positions of adjacent extrusion shafts is less than the width of the sleeve, when the flat sleeve passes between the shafts, it is compressed by the force of the shafts into an open shape. This results in creases on both the top and bottom surfaces of the sleeve, making it easier to expand the sleeve after entering the sleeve expansion mechanism for attaching it to the wire. This is particularly suitable for conveying sleeves wound in a flat shape on a tray. Simultaneously, guide rollers and guide blocks in the front and rear directions of the extrusion shafts provide guidance, ensuring the sleeve's forward direction is not skewed. Furthermore, the channels in the guide blocks allow the sleeve to return to a flat shape after being compressed by the extrusion shafts, facilitating subsequent cutting by the tube cutter.

[0090] In addition, the terminal crimping mechanism 62 can completely adopt the existing terminal crimping machine to perform the terminal crimping process, and the structure thereof will not be expanded here.
