Description

A rubber pipe forming cooling device

Technical Field

The utility model relates to the technical field of rubber tube molding, and in particular to a rubber tube molding cooling device.

Background Art

The production of rubber tubes usually uses latex styrene-butadiene rubber, nitrile rubber, chloroprene rubber, etc. as the main raw materials. In the production process, rubber tubes need to go through: rubber mixing, mixing rubber and various auxiliary materials to make them fully dispersed and uniform, so as to achieve the purpose of improving strength and durability; extrusion molding, the mixed rubber material is extruded through a mold to form it into the required shape and size; vulcanization treatment, putting the rubber product into a vulcanization tank for heating treatment, so that it is vulcanized and cross-linked, thereby improving strength and durability.

After the rubber is extruded by the extruder, it needs to be surface treated. Usually, it is coated with rubber and the outer wall of the rubber tube is branded with a suitable tool. These processes are all carried out under high temperature. After the surface treatment, the surface temperature of the rubber is very high and needs to be cooled. The existing technology usually adopts the direct cooling method, which causes the temperature of the rubber tube to drop suddenly. Due to thermal expansion and contraction, the rubber tube will deform.

In this embodiment, when a worker wants to cool down the rubber tube after surface treatment, he uses an appropriate tool to place the rubber tube into the precooling box 3. The high-temperature rubber tube is precooled in the precooling box and then enters the cooling box 2 for cooling. It can be understood that the precooling temperature in the precooling box 3 is higher than the cooling temperature in the cooling box 2. The cooling method in the precooling box 3 and the cooling box 2 can be: cold air is introduced into the precooling box 3 and the cooling box 2 respectively, wherein the temperature of the cold air introduced into the precooling box 3 is higher than the temperature of the cold air introduced into the cooling box 2; or water is introduced into the precooling box 3 and the cooling box 2 respectively, wherein the temperature of the water introduced into the precooling box 3 is higher than the temperature of the water introduced into the cooling box 2. Direct low-temperature cooling of the rubber tube is avoided, and the precooling box 3 allows the rubber tube to adapt to the low-temperature environment to prevent the rubber tube from deforming after suddenly entering the low-temperature environment.

In this embodiment, the second water pump 601 pumps the water in the water tank 4 directly into the pre-cooling box 3, ensuring that the water temperature entering the pre-cooling box 3 is different from the water temperature entering the cooling box 2, ensuring that the cooling temperatures of the pre-cooling box 3 and the cooling box 2 are different, so that the high-temperature rubber tube is pre-cooled before being cooled, preventing the high-temperature rubber tube from being directly cooled and causing deformation.

In this embodiment, the inner bottom of the cooling box 2 is provided with a plurality of water outlet holes 7 for discharging the water inside the cooling box 2; the overflow pipe 8 prevents the water inside the cooling box 2 from overflowing; when the water level inside the cooling box 2 is higher than the third water inlet 801, the water will flow from the overflow pipe 8 into the water tank 4; when the water level inside the cooling box 2 is located below the third water inlet 801, the water in the cooling box 2 will only flow from the water outlet holes 7 into the water tank 4. The water inside the cooling box 2 is recycled to avoid wasting water resources.

Furthermore, it also includes: a track wheel set 9, which is arranged at the bottom of the cooling box 2; the tooling table 1 is a chain drive table, which drives the tooling table 1, and the track wheel set 9 moves on the tooling table 1.

In this embodiment, the clamping block 112 is arc-shaped, ensuring that the outer wall of the rubber tube is not damaged when the clamping block 112 contacts the rubber tube; the working process of the positioning device 11 is as follows: when the high-temperature rubber tube passes through the first feed port 301 and penetrates into the precooling box 3, the rubber tube may deviate toward the inner bottom or top of the precooling box 3. At this time, the worker drives the two screw rods 111 at the same time to move the two clamping blocks 112 upward or downward along the height direction of the pre-cooling box 3. When the two clamping blocks 112 are respectively located on both sides of the rubber tube, the worker stops driving the screw rod 111, and then the worker drives the centering device 10 to clamp the rubber tube; then the two screw rods 111 are driven at the same time again to move the two clamping blocks 112 upward or downward. When the rubber tube is concentric with the first feed port 301 and the second feed port 201, the forward and reverse screws 101 are driven again to separate the two clamping blocks 112 but not completely separate. At this time, the rubber tube is concentric with the first feed port 301 and the first discharge port 302. The screw rod 111 can be driven to rotate by a hand wheel or a motor to prevent the rubber tube from deviating when entering, exiting the pre-cooling box 3 and entering the cooling box 2, thereby saving time and improving work efficiency.
