Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, and in particular provides a twisted core wire laminating machine. Background Art

[0002] Communications cables are widely used. However, when connecting electrical connections in specialized environments, such as between outdoor devices, underwater devices, outdoor and indoor devices, or underwater and surface devices, gaps can form between the multi-stranded wires within the otherwise surface-sealed cable. During use, water vapor or rainwater can seep through these gaps into devices (such as cameras), causing fogging of the camera, which directly affects the camera's quality and lifespan.

[0003] In order to solve the problem of gaps in the twisted core wire, the industry has adopted methods such as segmented hot melt glue injection or segmented hot melt tin injection to achieve blocking and waterproofing.

[0004] However, this method of filling the gaps by segmented hot-melt glue injection or segmented hot-melt tin injection can neither fill the gaps of the entire stranded core wire nor is it convenient to operate. Therefore, the business has developed a method to solve the problem of filling the gaps of the entire stranded core wire, for example: a glue injection device is set at the wire inlet of the stranding machine nozzle to achieve the purpose of filling the gaps of the entire stranded core wire.

[0005] However, although the method of setting up a glue injection device at the wire inlet of the stranding machine nozzle to inject glue can achieve the purpose of filling the gaps in the stranded core wires, this method is difficult to control the temperature of the glue liquid. It can neither ensure that the glue liquid of the entire stranded core wire is completely injected and filled, thereby affecting product quality, nor can it effectively increase the speed of the stranding machine nozzle, thereby affecting production capacity.

[0040] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0041] In this embodiment, if Figures 1 to 11The figure shows a stranded wire laminating machine, which belongs to the automatic machine series and includes a frame 10, a hot glue unit 20, a laminating unit 30 and a wire pressing unit 40, wherein:

[0042] The frame 10 is formed by connecting angle steel or strip profiles and is a double-sided support structure. One side of the frame includes three long, equal-length horizontal steel bars and two equal-length vertical columns 11. The three long, equal-length horizontal steel bars are arranged in parallel and their ends are perpendicularly connected to the vertical columns 11, forming a single-sided frame. The single-sided frame is vertically connected to another single-sided frame of the same structure via crossbeams (not marked) to form the frame (i.e., a "double-sided support structure") 10. In the frame, the ends of a pair of horizontally parallel horizontal steel bars 11 are connected perpendicularly to the lower ends of the vertical columns to form lower horizontal flat steel bars 12; the ends of another pair of horizontally parallel horizontal steel bars 11 are connected perpendicularly to the upper ends of the vertical columns to form upper horizontal flat steel bars 14; and a middle horizontal flat steel bar 13 is located between the upper horizontal flat steel bars 14 and the lower horizontal flat steel bars 12.

[0043] The hot glue part 20 includes a bracket 21, a hot melt chamber 22, a liquid flow pipe 23 and a cavity cover 24 covering the opening of the hot melt chamber 22, wherein: the hot glue part 20 is positioned on the horizontal flat steel 14 on the frame 10 through the bracket 21, and the bracket 21 is arranged on the upper horizontal flat steel 14 near one side of the cross arm. The hot melt chamber 22 includes a square hot plate 211 and a melting chamber body 221. The square hot plate 211 is supported on the frame 10 by the bracket 21 and connected to the distribution box (not marked) through wires. Since the distribution box does not belong to the design points of the present invention, it is not specifically described here; the liquid flow pipe 23 passes through the hot melt chamber 22 and is arranged on the side of the hot melt chamber 22 away from the cross arm, so that the outlet 231 of the liquid flow pipe 23 is above the glue passing part 30;

[0044] The gluing part 30 includes a groove part 31 and a cover part 32, wherein: the groove part 31 includes an elongated hot plate 311 and an elongated groove 312 arranged close to the elongated hot plate 311. The elongated hot plate 311 is arranged on the upper horizontal flat steel 14 so as to be displaceable forward and backward, and one end passes through the bracket 21 (below the hot melt cavity 22) and makes the end (not marked) flush with the outer side of the cross arm, while the other end of the elongated hot plate 311 is located on the upper horizontal flat steel 14 close to (corresponding to) the other cross arm. In this example, the elongated hot plate 311 is connected to the distribution box (not marked) via wires. Since the distribution box is not a key design feature of the present invention, it will not be specifically described here. The elongated slot 312 includes a slot cavity 3121 and a funnel 3122 connected to one end of the slot cavity 3121, and a filter screen 3123 disposed between the slot cavity 3121 and the funnel 3122. The slot cavity 3121 has a protrusion (not marked) with a limiting hole (not marked) across the two walls of the slot cavity and close to both ends of the slot cavity. The cover 32 includes a side plate 321 and a cover plate 322. The lower side surface (not marked) of the side plate 321 is fixed to the upper horizontal flat steel 14 on one side of the frame 10 (i.e., the manual operation side). The cover plate 322 covers the elongated slot 312 and is connected to the upper side surface (not marked) of the side plate 321 by rotation via a hinge 323, so that the cover plate 322 can be opened / closed on the elongated slot 312. In this example, the hinge 323 includes a hinge 3231 on one side of the side panel 321 and a hinge (not marked) on the other side of the cover panel 322 that is compatible with the hinge 3231 on one side of the side panel 321 . The side panel hinge 3231 and the cover panel hinge 3231 are connected via a hinge shaft 3232 .

[0045] The wire pressing part 40 is positioned on one side of the frame and extends upward to form a lifting part (not marked). The lifting part is connected to a cross arm 41, and the cross arm 41 forms a support arm 42 downward. A wire pressing wheel (or "wire dividing wheel") 43 is vertically positioned at the end of the support arm 42 by an outwardly extending axis so that the wire pressing wheel 43 is in the middle of the width of the elongated slot 312, and the depth of the position of the wire pressing wheel 43 in the elongated slot 312 is driven by (control) the lifting part. In this example, the lifting part includes a cylinder 44, and the other end of the cross arm 41 relative to the support arm is vertically connected to the telescopic shaft of the cylinder 44. So that the wire pressing wheel 43 is suspended in the elongated slot 312 and controlled by the cylinder 44 to achieve up and down displacement.

[0046] In this embodiment, if Figures 4 to 9 and Figure 11 , the picture shows the stranded wire laminating machine:

[0047] The frame 10 also includes a front support (

[0048] not labeled), middle pillar (not labeled), and rear pillar (not labeled);

[0049] The groove portion 31 further includes a strip toothed member 313 and a hand crank member 314, wherein: the strip toothed member 313 is centrally located in the middle of the width of the back of the elongated hot plate 311, so that the strip toothed member 313 and the elongated hot plate 311 are integrated; the hand crank member 314 includes a rotating shaft 3141 and a gear 3142, a handle 3143 and a bearing 3144 provided on the rotating shaft 3141, the gear 3142 is adapted to the strip toothed member 313 and can be driven to shift forward and backward by shaking; the bearing 3144 is on the rotating shaft 3141 141 is equidistantly located on both sides of the gear 3142, and the two bearings 3144 are respectively fixed to the inner sides of the opposite middle pillars on both sides of the frame 10 close to the upper horizontal steel 14. The handle 3143 is a disc handle fixed to one end of the rotating shaft 3141. When the handle is manually operated, the rotating shaft 3141 drives the gear 3142 and shifts the bar-shaped toothed member 313 through the gear 3142, so that the bar-shaped toothed member 313 formed as one piece with the elongated hot plate 311 drives the elongated hot plate 311 to achieve adjustment (forward and backward) displacement on the frame;

[0050] In order to ensure that the elongated hot plate 311 can be smoothly displaced as required and reduce the friction between the elongated hot plate 311 and the frame, the groove portion 31 also includes a rail wheel component 315, and the rail wheel component 315 includes a rail wheel shaft 3151 and track wheels 3152 respectively provided at both ends of the rail wheel shaft 3151. The corresponding outer sides of the two track wheels 3152 are respectively formed with convex edges (not marked) protruding from the track wheels 3152 along the outer periphery of the track wheels 3152. The rail wheel component 315 is divided into front and rear rail wheel components 315, which are respectively positioned on the front and rear pillars close to the upper horizontal steel 14 through the rail wheel shaft 3151. When the elongated hot plate 311 falls on the track wheel 3152, it is limited by the convex edge of the rail wheel shaft 3151, so that the elongated hot plate 311 can only be displaced forward and backward on the track wheel 3152 and will not automatically fall off from both sides.

[0051] In this embodiment, the hot glue unit 20 has a liquid flow valve (not shown) in the liquid flow tube 23. The valve can control the flow of glue in the hot melt chamber 22 and also control the flow of glue through the liquid flow tube 23 into the groove cavity 3121. The elongated groove 312 is closely attached to the elongated hot plate 311 and moves with the displacement of the elongated hot plate 311, so as to adjust the elongated groove funnel 3122 to abut the wire nozzle (not shown) of an external device (such as a "twisting machine").

[0052] In this embodiment, if Figure 11The core wire (such as metal wire) shown in the figure is a multi-strand core wire 100. The multi-strand core wire 100 is collected in the wire limiting hole of the groove cavity 3121 on the wire rack (not shown) and passes through the wire limiting hole at the front end of the groove cavity to the bottom of the wire pressure wheel 43 in the groove cavity 3121, and then passes through the wire limiting hole at the rear end of the groove cavity to the wire mouth of the stranding machine. During the production process, when the multi-strand core wire 100 passes through the groove cavity 3121 filled with glue, the surface of the multi-strand core wire 100 will be adhered to the glue. When the multi-strand core wire 100 with glue is twisted through the wire mouth of the stranding machine, the glue will overflow from the wire mouth. The glue overflowing from the wire mouth will be received by the funnel 3122. Since the glue received by the funnel 3122 is separated from the heat source and has a lower temperature than the heated glue in the groove cavity 3121, it will gradually solidify. In order to avoid the glue with temperature difference from directly mixing and affecting the "glue-wrapped wire" effect, the funnel 3122 will intercept the gradually solidified glue through the filter 3123 to the groove cavity.

[0053] The glue heated in the cavity 3121 gradually transfers heat, causing the gradually solidified glue in the funnel 3122 to melt and flow into the cavity 3121 through the filter screen 3123 to be mixed and reused.

[0054] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0055] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
