Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically to an extrusion mechanism for a two-color co-extrusion equipment for cable insulation layers. Background Technology

[0002] Double-layer co-extruded cable is a type of wire and cable with a double-layer insulation structure. The cable insulation layer two-color co-extrusion equipment is a type of equipment used to produce cable insulation layers with two different colors. This equipment uses a special processing method to simultaneously extrude two different colored materials to form insulation layers with two colors.

[0003] In the production of wires and cables, especially in situations where special color markings are required or the aesthetics of the product are enhanced, such as charging piles for new energy vehicles and photovoltaic lines, this technology is needed to ensure safety and aesthetics. Therefore, dual-color co-extrusion equipment for cable insulation is used, and the extrusion mechanism is used in conjunction with this equipment. When the extrusion mechanism is in use, it usually uses pressure to complete the extrusion of materials. Since two colors of materials are required, uneven distribution of the two colors is likely to occur, affecting the extrusion effect. Utility Model Content

[0004] The purpose of this utility model is to provide an extrusion mechanism for a two-color co-extrusion equipment for cable insulation layers, in order to solve the problem mentioned in the background art that a two-color co-extrusion equipment for cable insulation layers is used, and the extrusion mechanism is used in conjunction with the equipment. When the extrusion mechanism is in use, it usually uses pressure to complete the extrusion of materials. Since two colors of materials are required, there is a tendency for uneven distribution of the two colors, which affects the extrusion effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion mechanism for a two-color co-extrusion equipment for cable insulation, comprising a first support frame, an insulation box, and a second support frame. A feed inlet is mounted on the upper side of the insulation box. A connecting pipe is connected to the bottom of the insulation box, and an extrusion cylinder is connected to the tail end of the connecting pipe. A partition plate is mounted at the middle position of the top of the extrusion cylinder, and an extrusion port is connected to the bottom of the extrusion cylinder. A cylinder is mounted at the top of the second support frame, and a hydraulic telescopic rod is connected to the output end of the cylinder.

[0006] Preferably, the connecting pipes are symmetrically distributed about the central axis of the extrusion cylinder, and the tail end of the connecting pipes is connected to the interior of the extrusion cylinder.

[0007] Preferably, the end of the feed inlet is connected to the inside of the insulation box, and a solenoid valve is installed inside the extrusion port.

[0008] Preferably, the front end of the insulated box is equipped with an observation window, and the tail end of the hydraulic telescopic rod is connected to a compression plate.

[0009] Preferably, a protective pad is fixed to the bottom of the extrusion plate, and grooves are formed on both sides of the extrusion plate, with ball bearings embedded in the grooves.

[0010] Preferably, the grooves are evenly distributed on both sides of the extrusion plate, and the inner diameter of the grooves is larger than the outer diameter of the ball.

[0011] Preferably, an arc-shaped mounting plate is fixed at both the upper and lower positions of the inner wall of the feed inlet, a filter plate is connected to the side of the arc-shaped mounting plate, a mounting bolt is connected between the arc-shaped mounting plate and the filter plate, and the arc-shaped mounting plates are symmetrically distributed about the central axis of the feed inlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the extrusion mechanism of this cable insulation layer dual-color co-extrusion equipment not only improves the extrusion effect, but also improves the raw material feeding filtration capacity and pressure application capacity of the extrusion mechanism.

[0013] (1) By installing and fixing the partition plate in the middle position of the upper part of the extrusion cylinder, the two heat preservation boxes work separately, and then the two cylinders work at the same time to drive the hydraulic telescopic rod to extend and retract. After the extrusion plate is connected to the end of the hydraulic telescopic rod, the extrusion plate works to form the extrusion work. The extrusion effect can be observed at the observation window. After extrusion, the material flows through the connecting pipe to the extrusion cylinder. After the two connecting pipes are connected, both materials reach the extrusion cylinder. After being separated by the partition plate, they finally converge at the end of the extrusion cylinder and are finally discharged at the extrusion port. In this way, the overall extrusion effect is improved in the working process.

[0014] (2) By assembling the feed inlet on the side of the insulation box, the feed inlet can be used for feeding raw materials. Arc-shaped mounting plates are fixed at the upper and lower positions of the inner wall of the feed inlet. The connection between the arc-shaped mounting plates and the filter plates is completed by using mounting bolts. Therefore, during the feeding process, the filter plates can be used to form a filtration process, which improves the overall raw material feeding filtration capacity.

[0015] (3) After the cylinder works, it can drive the hydraulic telescopic rod to form a telescopic operation. After the extrusion plate is connected to the end of the hydraulic telescopic rod, the extrusion plate works to form an extrusion operation. The bottom of the extrusion plate is fixed with a protective pad, and grooves are opened on both sides of the extrusion plate. Balls are embedded in the grooves. Therefore, when the extrusion plate moves to apply pressure, the ball and the groove can cooperate to complete the rolling protection, thereby improving the overall pressure application capacity in the working process.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 An embodiment of this utility model provides an extrusion mechanism for a two-color co-extrusion equipment for cable insulation, comprising a first support frame 1, an insulation box 6, and a second support frame 8. A feed inlet 7 is installed on the upper side of the insulation box 6. A connecting pipe 5 is connected to the bottom of the insulation box 6. An extrusion cylinder 2 is connected to the tail end of the connecting pipe 5. A partition plate 3 is installed at the middle position of the top of the extrusion cylinder 2. An extrusion port 4 is connected to the bottom of the extrusion cylinder 2. A cylinder 9 is installed at the top of the second support frame 8. A hydraulic telescopic rod 10 is connected to the output end of the cylinder 9.

[0023] The connecting pipe 5 is symmetrically distributed about the central axis of the extrusion cylinder 2, and the tail end of the connecting pipe 5 is connected to the interior of the extrusion cylinder 2.

[0024] The end of the feed inlet 7 is connected to the inside of the insulation box 6, and a solenoid valve is installed inside the extrusion port 4.

[0025] The front end of the insulated box 6 is equipped with an observation window 12, and the tail end of the hydraulic telescopic rod 10 is connected to a compression plate 11.

[0026] A protective pad 13 is fixed to the bottom of the extrusion plate 11, and grooves 15 are opened on both sides of the extrusion plate 11, with ball bearings 14 embedded in the grooves 15.

[0027] The grooves 15 are evenly distributed on both sides of the extrusion plate 11, and the inner diameter of the grooves 15 is larger than the outer diameter of the balls 14.

[0028] Arc-shaped mounting plates 16 are fixed at the upper and lower positions of the inner wall of the feed inlet 7. Filter plates 17 are connected to the sides of the arc-shaped mounting plates 16. Mounting bolts 18 are connected between the arc-shaped mounting plates 16 and the filter plates 17. The arc-shaped mounting plates 16 are symmetrically distributed about the central axis of the feed inlet 7.

[0029] The two insulation boxes 6 work separately. After the two cylinders 9 work simultaneously, they drive the hydraulic telescopic rod 10 to extend and retract. After the extrusion plate 11 is connected to the tail end of the hydraulic telescopic rod 10, the extrusion plate 11 works to form an extrusion operation. Therefore, the raw material can be extruded at the same time and then flow through the connecting pipe 5 to the extrusion cylinder 2.

[0030] Furthermore, mounting bolts 18 are used to complete the connection and assembly between the arc-shaped mounting plate 16 and the filter plate 17, thus the mounting bolts 18 serve the purpose of being able to be assembled and disassembled.

[0031] After being further separated by the partition plate 3, they finally converge at the tail end of the extrusion cylinder 2. Therefore, the upper part of the partition plate 3 is fixed to the upper part of the inner wall of the extrusion cylinder 2, while the lower part of the partition plate 3 is suspended.

[0032] Working principle: First, the partition plate 3 is installed and fixed in the upper middle position inside the extrusion cylinder 2. The two heat preservation boxes 6 work separately. Then, the two cylinders 9 work simultaneously to drive the hydraulic telescopic rod 10 to extend and retract. After the extrusion plate 11 is connected to the tail end of the hydraulic telescopic rod 10, the extrusion plate 11 works to form the extrusion work. The extrusion effect can be observed at the observation window 12. After extrusion, the material flows through the connecting pipe 5 to the extrusion cylinder 2. After the two connecting pipes 5 are connected, both materials reach the extrusion cylinder 2. After being separated by the partition plate 3, they finally converge at the tail end of the extrusion cylinder 2 and are finally discharged at the extrusion port 4.
