Description

Technical Field

[0001] The utility model relates to the technical field of rubber runway manufacturing, in particular to a die head of a rubber runway coil extruder. Background Art

[0002] Existing prefabricated rubber coil runways generally adopt calendering or extrusion process, but the temperature of the rubber coil coming out of the extruder is relatively high, and it has not yet been vulcanized, so the rubber has no strength. If there is a slight unbalanced external force, the rubber will deform and break. Due to cost control and physical property considerations, a large amount of rubber powder is added to the formula of rubber runway coils, which leads to poor fluidity of the unvulcanized rubber material. Using traditional square dies will lead to uneven discharge, uneven edges after the upper and lower layers are bonded, insufficient rubber on the surface, and leakage of rubber on the bottom layer. In addition, when the runway is extruded, it is generally transported directly through the conveyor belt used to transport the runway. There will be a certain distance between the conveyor belt and the square die, so sometimes the runway will break at the connection between the conveyor belt and the square die. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing extruder die head causes uneven material discharge, easily leaks rubber material to the bottom, and easily causes the extruded runway to break due to a certain distance between the conveyor belt and the square die.

Two support plates are hinged on both sides of the die head body, and two conveyor belt structures are provided between the two support plates. Connecting rods are fixed on both sides of the two conveyor belt structures close to one end, and a telescopic rod is rotatably provided on the outer side of the connecting rod. An arc-shaped notch is opened on the side of the support plate at the connecting rod, and a connecting frame is fixed on the side of the telescopic rod, and one side of the connecting frame is rotatably set on one side of the support plate.

[0005] As a further solution of the present invention: a connecting rod 1 is fixed near the bottom between the two support plates, a connecting rod 2 is fixed below one side of the die body, and several hydraulic rods are provided between the connecting rod 1 and the connecting rod 2. The two ends of the hydraulic rods are respectively rotatably connected to the connecting rod 1 and the connecting rod 2. The hydraulic rods are used to control the swing angle of the support plates.

[0006] As a further solution of the present invention: a square die outlet is opened on one side of the die body, and the conveyor belt structure is located below the square die outlet to facilitate direct reception of the extruded rubber runway.

[0007] As a further solution of the present invention, the connecting rod slides in the arc-shaped notch to limit the swing range of the conveyor belt structure.

[0008] As a further solution of the present invention: the telescopic rod, the conveyor belt structure, and the induction solenoid valve are electrically connected to an external power supply respectively, and the hydraulic rod is interconnected with an external hydraulic control device.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides a technical solution for solving the existing problems raised in the background technology.

[0020] Combined with attachment Figure 1-3 It can be learned that it includes a die body 1, which is divided into an upper rubber material channel 1.1 and a lower rubber material channel 1.2. Several induction solenoid valves 2 are fixed at the upper rubber material channel 1.1 and the lower rubber material channel 1.2. Two support plates 3 are hinged on both sides of the die body 1, and two conveyor belt structures 4 are provided between the two support plates 3. A connecting rod 1 8 is fixed between the two support plates 3 near the bottom, and a connecting rod 2 9 is fixed at the bottom of one side of the die body 1. Several hydraulic rods 10 are provided between the connecting rod 1 8 and the connecting rod 2 9. The two ends of the hydraulic rod 10 are respectively rotatably connected to the connecting rod 1 8 and the connecting rod 2 9. The hydraulic rod 10 is used to control the swing angle of the support plate 3; a square die outlet 1.3 is opened on one side of the die body 1, and the conveyor belt structure 4 is located below the square die outlet 1.3, which is convenient for directly receiving the extruded rubber runway; the telescopic rod 6, the conveyor belt structure 4, and the induction solenoid valve 2 are electrically connected to the external power supply respectively, and the hydraulic rod 10 is connected to the external hydraulic control device.

[0021] Combined with attachment Figure 4 、 5 It can be seen that connecting rods 5 are fixed on both sides of the two conveyor belt structures 4 close to one end, and a telescopic rod 6 is rotatably provided on the outer side of the connecting rod 5. An arc-shaped slot 3.1 is opened on the side of the support plate 3 at the connecting rod 5, and a connecting frame 7 is fixed on the side of the telescopic rod 6. One side of the connecting frame 7 is rotatably set on the side of the support plate 3; the connecting rod 5 slides in a limited position in the arc-shaped slot 3.1, which can limit the swing range of the conveyor belt structure 4.

[0022] The working principle of the present application is as follows: when manufacturing a rubber runway, the rubber material is first passed into the die body 1, wherein the upper rubber material channel 1.1 and the lower rubber material channel 1.2 respectively use rubber materials of different colors. During the extrusion process, the flow rate of the extruded rubber material can be controlled by a plurality of induction solenoid valves 2, so that the rubber material extrusion is more stable;

[0023] The extruded runway will first fall onto the conveyor belt structure 4 located below the square die outlet 1.3. The telescopic rod 6 and the hydraulic rod 10 are used to control the swing of the conveyor belt structure 4 and the support plate 3 respectively, so as to make the output of the rubber runway more stable, so that it can be completely transported to the runway conveyor belt to facilitate the next embossing process.
