Description

Technical Field

[0001] This invention relates to the field of cable production technology, and in particular to a cable core coating and forming device for cable production. Background Technology

[0002] In the current technology, cables often need to be wrapped with a layer of rubber during processing to achieve insulation, which requires a wrapping molding device.

[0003] The existing overcoating equipment still has the following problems during use: In the process of overcoating the cable core, the overcoating equipment usually needs to cool the overcoated cable core and the overcoating rubber. However, traditional natural cooling or air cooling is not effective due to the long time or the fact that the cold air does not contact the surface of the overcoating rubber evenly when blowing air. This affects the cooling effect on the overcoated cable core and the overcoating rubber. Summary of the Invention

[0004] The purpose of this invention is to provide a cable core coating molding device for cable production, which is beneficial to improving the cooling effect on the coated cable core and the coating rubber.

[0005] To achieve the above objectives, the present invention provides a cable core coating and forming apparatus for cable production; including a base plate on which a coating machine is mounted, and a cooling assembly; The cooling assembly includes a cooling tank, guide roller assembly, limiting brackets, hangers, limiting rollers, and side limiting components. The cooling tank is filled with cooling water, and the guide roller assembly is arranged on both sides. Multiple limiting brackets are installed inside the cooling tank, and the hanger is installed at the bottom. The limiting rollers are rotatably mounted on the hangers. The multiple limiting rollers work in pairs and are below the cooling water surface. The side limiting components are arranged on both sides of the limiting rollers.

[0006] The cooling box has notches on the top of both sides to facilitate cable passage, a drain valve at the bottom of the rear side, and a water temperature detection mechanism installed on the side wall.

[0007] The side limiting component includes a horizontal plate and a mating component. The horizontal plate is detachably connected to the limiting bracket and is symmetrically arranged on the top side of the hanger. The mating component is located at the bottom of the horizontal plate and close to the limiting roller.

[0008] The mating components include bearing seats and vertical rollers. Multiple bearing seats are installed at the bottom of the horizontal plate and arranged in a line with intervals. The vertical rollers are rotatably mounted on the bearing seats and are symmetrically arranged on both sides of the limiting roller.

[0009] The coating machine is equipped with support roller sets on both the feed side and the discharge side for cable guidance and support.

[0010] The cable core coating and forming device for cable production also includes a lifting assembly, which includes a fixed frame and a power component. The fixed frame is detachably connected to the cooling box and is located on the rear side of the cooling box; the power component is located on the side of the fixed frame near the limiting bracket.

[0011] The power component includes a drive unit and a connecting frame. The drive unit is mounted on the top of the fixed frame, and its output end is connected to the connecting frame. The connecting frame is detachably connected to the plurality of limiting brackets.

[0012] The present invention discloses a cable core coating molding device for cable production. The device uses a coating machine to coat the cable with a rubber layer. The coated cable enters a cooling box. At this time, multiple limiting rollers and side limiting components work together to stably limit the cable below the cooling water, so that the surface of the cable can be evenly contacted with the cooling water to achieve cooling. Finally, the cooled cable is discharged from the cooling box and wound by a winding device, which helps to improve the cooling effect on the coated cable core and the rubber coating.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] First embodiment: like Figure 1 and Figure 2 As shown, where Figure 1 This is a front view of a cable core coating and molding device used in cable production. Figure 2 This is a schematic diagram of a hanger structure. The present invention provides a cable core coating and forming device for cable production: it includes a base plate 101, a coating machine 102, and a cooling assembly. The cooling assembly includes a cooling box 103, a guide roller group 104, a limiting bracket 105, a hanger 106, a limiting roller 107, and a side limiting component. The side limiting component includes a horizontal plate 108 and a mating component, which includes a bearing seat 109 and a vertical roller 110. The aforementioned solution improves the cooling effect on the coated cable core and the coated rubber. It is understood that the aforementioned solution can improve the cooling effect on the coated cable core and the coated rubber.

[0023] In this embodiment, a coating machine 102 is mounted on the base plate 101. The coating machine 102 can be a mature device already available in the prior art. Furthermore, all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The control method is automatic control via a controller. The controller's control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is primarily for protecting mechanical devices, the control method and circuit connections will not be explained in detail here.

[0024] Preferably, the cooling tank 103 is filled with cooling water, and guide roller groups 104 are arranged on both sides. Multiple limiting brackets 105 are installed inside the cooling tank 103, and a hanger 106 is installed at the bottom. Limiting rollers 107 are rotatably mounted on the hanger 106. The multiple limiting rollers 107 work in pairs and are below the cooling water surface. Side limiting components are arranged on both sides of the limiting rollers 107. The guide roller groups 104 are used for cable guidance. The L-shaped ends of the limiting brackets 105 are connected to the inner wall of the cooling tank 103 via positioning pins and bolts. The installation arrangement of the limiting brackets 105 can be set to create a U-shaped or S-shaped guiding structure for the cable inside the cooling tank 103 (extending the contact time between the cable and the cooling water). The limiting rollers 107 are used to limit the cable in the vertical direction. The side limiting components help ensure that the cable is stably positioned on the limiting rollers 107, preventing the cable from falling off the sides of the limiting rollers 107. The hanger 106 is a U-shaped structure composed of two detachable brackets, and the fixing part of the bracket is installed at the bottom of the limiting bracket 105 by positioning pins and bolts.

[0025] Preferably, the cooling box 103 has notches on both sides of the top to facilitate cable passage, and a drain valve is provided at the bottom of the rear side. A water temperature detection mechanism is also installed on the side wall. The notches facilitate cable passage, and the drain valves allow water to drain from the cooling box 103. The water temperature detection mechanism uses a temperature sensor to detect the water temperature and feeds the temperature data back to the control system (PLC). Simultaneously, the rear side of the cooling box 103 is equipped with automatic water pumping and replenishment pipes. When the internal water temperature is high, the automatic water pumping pipe automatically removes the hot water from the cooling box 103 (at this time, the coating machine 102 and the external winding equipment stop working). Then, the replenishment pipe pumps low-temperature cooling water into the cooling box 103. The temperature sensor detects the temperature, and the water level sensor on the side wall of the cooling box 103 detects the water level, ensuring the water level is adequate and facilitating automatic water replenishment and stop control.

[0026] Preferably, the horizontal plate 108 is detachably connected to the limiting bracket 105 and is symmetrically arranged on the top side of the hanger 106; the mating component is located at the bottom of the horizontal plate 108 and close to the limiting roller 107. The horizontal plate 108 is fixed by positioning pins and bolts, and the mating component is used to prevent the cable from falling off from both sides of the limiting roller 107.

[0027] Preferably, multiple bearing seats 109 are installed at the bottom of the horizontal plate 108 and arranged in a straight line; the vertical rollers 110 are rotatably mounted on the bearing seats 109 and symmetrically arranged on both sides of the limiting rollers 107. The bearing seats 109 have a T-shaped structure and are fixed by positioning pins and bolts. The top mounting end of the vertical roller 110 is mounted on the bearing seat 109 by a rotating bearing. A through hole is provided at the top of the horizontal plate 108 to avoid the stepped shaft end of the top mounting shaft of the vertical roller 110.

[0028] Preferably, the coating machine 102 is provided with support roller groups 111 on both the feed side and the discharge side for cable guidance and support. This structure will help improve the stability of cable input and output of the coating machine 102. The support structure of the guide roller group 104 (not shown in the figure) is set with reference to the support roller group 111 support structure to ensure stable rotation.

[0029] When using this invention to improve the cooling effect on the coated cable core and the rubber coating, the rubber layer is coated by the coating machine 102. The coated cable enters the cooling box 103. At this time, multiple limiting rollers 107 and vertical rollers 110 cooperate to stably limit the cable below the cooling water, so that the cable surface can be evenly contacted with the cooling water to achieve cooling. Finally, the cooled cable is discharged from the cooling box 103 and wound by a winding device. In practice, a warm air blowing device can also be set between the cable outlet of the cooling box 103 and the winding device to blow warm air onto the cable surface to achieve surface drying. When the cable passes through the gap between the two limiting rollers 107, no cooling water is added to the cooling box 103 to prevent water from entering the interior from the cable end. Cooling water is added after the cable is threaded through, which helps to improve the cooling effect on the coated cable core and the rubber coating.

[0030] Second embodiment: like Figure 3 and Figure 4 As shown, where Figure 3 This is a front view of a cable core coating and molding device used in cable production. Figure 4 This is a schematic diagram of the connecting frame. Based on the first embodiment, the present invention provides a cable core coating and forming device for cable production. The cable core coating and forming device for cable production further includes a lifting assembly, which includes a fixed frame 201 and a power component. The power component includes a drive component 202 and a connecting frame 203.

[0031] The fixing frame 201 is detachably connected to the cooling box 103 and is located on the rear side of the cooling box 103; the power component is located on the side of the fixing frame 201 near the limiting bracket 105. The fixing frame 201 is fixed by positioning pins and bolts, and the power component is used to move the limiting bracket 105 and the hanger 106 out of the cooling box 103.

[0032] The driving component 202 is mounted on the top of the fixed frame 201, and its output end is connected to the connecting frame 203. The connecting frame 203 is detachably connected to the multiple limiting brackets 105. The driving component 202 is fixed by bolts and can be a power component such as a cylinder, hydraulic cylinder, electric telescopic rod, or servo cylinder. The output end of the driving component 202 is mounted on a disc by countersunk bolts, and the disc is connected to the connecting frame 203 by bolts. The connecting frame 203 is connected to the multiple limiting brackets 105 by bolts, and the integrated circular guide rods on both sides of the connecting frame 203 are slidably engaged with the T-shaped linear sliding bearings on the fixed frame 201.

[0033] In this embodiment, when performing maintenance on components such as the limiting roller 107 and the vertical roller 110, the driving component 202 can be controlled to move, thereby driving the connecting frame 203 upward and removing components such as the limiting roller 107 and the vertical roller 110 from the cooling box 103, facilitating maintenance operations.

[0034] Third embodiment: like Figure 5 and Figure 6 As shown, where Figure 5 This is a front view of a cable core coating and molding device used in cable production. Figure 6 This is a schematic diagram of the structure of a T-shaped tube. Based on the first embodiment, the present invention provides a cable core coating and forming device for cable production. The cable core coating and forming device for cable production also includes a guiding component, which includes a mating frame 301, an installation tube 302, and a T-shaped tube 303.

[0035] The mating frame 301 is detachably connected to the base plate 101, and the mounting tube 302 is welded to the top of the mating frame 301; the T-shaped tube 303 is detachably connected to the mounting tube 302 and is sleeved on the outside of the cable, and multiple rolling balls are arranged in a ring.

[0036] In this embodiment, the bottom end of the mating frame 301 is fixed by a positioning pin and bolts. The left end face of the mounting tube 302 is provided with a threaded hole and a pin hole to facilitate the fixing of the disc of the T-shaped tube 303 by the positioning pin and bolts. Multiple rolling balls (the multiple rolling balls have the same diameter and are spaced apart to ensure that the cable does not get stuck in the gap between two rolling balls, and the rolling balls slide in contact with the inner wall of the mounting tube 302) are provided on the annular surface of the T-shaped tube 303 for assistance. When the cable is subsequently transported to the winding equipment through the T-shaped tube 303, a limiting structure can be further formed to facilitate cable guidance.

[0037] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
