Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting equipment production, in particular to a forming device for a fire-fighting hose. Background Art

[0002] Fire hoses are hoses used to transport fire-retardant liquids such as high-pressure water or foam. Traditional fire hoses are lined with rubber and covered with flax woven fabric on the outside. Advanced fire hoses are made of polymer materials such as polyurethane. There are metal joints at both ends of the fire hose, which can be connected to another hose to extend the distance or connected to a nozzle to increase the liquid injection pressure. When processing the fire hose, a device is required to shape the fire hose.

[0003] The patent document with publication number CN218876228U discloses a fire hose forming device, including a base, an extrusion mechanism for extruding the cooled and formed fire hose to facilitate subsequent collection, and a supporting and collecting mechanism for supporting the fire hose to prevent the fire hose from spreading during collection. A cylinder is arranged above the base, and an extrusion device is connected to the lower end of the cylinder. A cooling water tank is arranged on one side of the extrusion device, and the extrusion mechanism is arranged on the side of the cooling water tank away from the extrusion device.

[0004] In the above technical solution, when the fire hose lining is extruded and cooled, it can only be cooled on the outside, so that the hose lining cannot be fully and evenly cooled, which may easily cause it to stick. Different cooling rates will form uneven residual stress inside the material, which may reduce the impact resistance of the material. Due to the uneven structure, the hose lining may have weaknesses when subjected to internal pressure, reducing the overall pressure resistance. In addition, the above design cannot adaptively adjust the cooling intensity according to actual conditions, and it is difficult to ensure the cooling molding effect. Therefore, we propose a fire hose molding device to solve this problem. Summary of the invention

[0031] 1. In the present invention, a fire hose forming device is described, by adding molten raw materials into a feed hopper, and starting a stirring motor and a heating ring, the stirring motor drives the stirring paddle to rotate to stir the raw materials, and the heating ring heats and keeps the raw materials warm to prevent the raw materials from solidifying, the raw materials flow into the extrusion barrel from the feed hopper, and the extrusion screw is driven to rotate by starting the extrusion motor, so that the raw materials are transported to the right and squeezed into between the inner barrel and the outer barrel, by starting two water pumps and driving the impeller to rotate by the motor, cooling water is introduced into the inner cooling pipe and the outer cooling pipe respectively, the heat in the inner barrel is taken away by the cooling water flowing in the inner cooling pipe, and the heat in the outer barrel is taken away by the cooling water in the outer cooling pipe, so that the inner barrel and the outer barrel are cooled to achieve synchronous cooling of the inner and outer walls of the forming material, the formed raw materials enter between the two extrusion wheels and are extruded into a flat shape, and then connected to the outer side of the winding drum, and the winding drum is driven to rotate by starting the servo motor to realize the winding of the formed fire hose lining;

[0032] 2. In the present invention, the fire hose forming device monitors the temperature of the cooling waste water flowing in through thermistors arranged in the two round shells. When the temperature of the cooling waste water rises, it means that the cooling effect on the forming material is insufficient, and when the temperature rises, the resistance of the thermistor decreases, thereby reducing the voltage value shared by it, thereby increasing the voltage value shared by the corresponding water pump, thereby increasing the power of the water pump, thereby increasing the output shaft speed of the motor, thereby increasing the rotation speed of the pump shaft and the impeller, thereby increasing the water delivery volume to improve the cooling effect;

When the power difference between the two water pumps is large enough, the pressing plate contacts the corresponding control button and controls the corresponding refrigerator to start, thereby cooling the cooling water entering the corresponding water pump to improve its cooling effect, thereby keeping the cooling rate of the inner and outer walls of the molding material consistent, thereby improving the molding quality;

[0034] 4. In the present invention, in the fire hose forming device, the connecting plate moves upward and drives the square plate to move upward through the vertical rod, thereby squeezing the push plate, the compression spring and the varistor, so that the compression spring undergoes elastic deformation and the resistance value of the corresponding varistor decreases.

A plurality of mounting rods are fixedly mounted on the bottom of the feed hopper 104, and the bottom ends of the mounting rods are fixedly mounted on the top of the extrusion barrel 201.

[0067] A plurality of fixing rods are fixedly installed at the bottom of the mounting plate 403, and the bottom of the fixing rods is fixedly installed at the top of the outer cylinder 301, and the outer cylinder 301 is fixedly installed at one end of the extrusion cylinder 201, and the outer sides of the outer cylinder 301 and the extrusion cylinder 201 are fixedly installed with the same frame 25, and the outer side of the extrusion cylinder 201 is fixedly installed with a reinforcement ring 203, and the reinforcement ring 203 is fixedly sleeved on the outer side of the outer cylinder 301;

[0068] An extrusion motor 202 is fixedly mounted on the other end of the extrusion barrel 201 , and an output end of the extrusion motor 202 is fixedly connected to an extrusion screw 204 .

[0069] In this embodiment, the outer side of the thermistor 405 is wrapped with a thermally conductive silicone sheet 406, and the thermally conductive silicone sheet 406 is fixedly connected in the corresponding round shell 404. The thermally conductive silicone sheet 406 has good thermal conductivity and good insulation performance, thereby preventing the thermistor 405 from being short-circuited by the cooling water flowing through it, and the top and bottom ends of the thermistor 405 are fixedly connected with a conductive wire 407, and the outer side of the conductive wire 407 is wrapped with an insulating tube, thereby preventing the conductive wire 407 from leaking electricity, and the conductive wire 407 is used to connect the circuit with the refrigerator 10;

[0070] The inner cooling pipe 402 and the outer cooling pipe 401 are both configured in a spiral shape, and the inner cooling pipe 402 is fixedly connected to the inside of the inner cylinder 302 , and the outer cooling pipe 401 is fixedly installed on the outside of the outer cylinder 301 .

[0071] In this embodiment, when in use, the molten raw materials are added into the feed hopper 104, and the stirring motor 101 and the heating ring 105 are started. The stirring motor 101 drives the stirring paddle 103 to rotate to stir the raw materials. At the same time, the heating ring 105 heats and keeps the raw materials warm to prevent the raw materials from solidifying. The raw materials flow from the feed hopper 104 into the extrusion barrel 201, and the extrusion motor 202 is started to drive the extrusion screw 204 to rotate, so that the raw materials are transported to the right and squeezed into the space between the inner barrel 302 and the outer barrel 301. The two water pumps 7 and the motor 705 are started to drive the impeller 703 to rotate. The cooling water is introduced into the inner cooling pipe 402 and the outer cooling pipe 401 respectively. The cooling water flowing in the inner cooling pipe 402 takes away the heat in the inner cylinder 302, and the cooling water in the outer cooling pipe 401 takes away the heat in the outer cylinder 301, thereby cooling the inner cylinder 302 and the outer cylinder 301, so as to achieve the synchronous cooling of the inner and outer walls of the molding material.

[0072] The temperature of the cooling wastewater flowing in is monitored by the thermistors 405 arranged in the two round shells 404. When the temperature of the cooling wastewater rises, it indicates that the cooling effect on the molding material is insufficient. When the temperature rises, the resistance of the thermistor 405 decreases, thereby reducing the voltage value shared by it, thereby increasing the voltage value shared by the corresponding water pump 7, thereby increasing the power of the water pump 7, thereby increasing the output shaft speed of the motor 705, thereby increasing the rotation speed of the pump shaft 704 and the impeller 703, thereby increasing the water delivery amount to improve the cooling effect.

[0073] The pump shaft 704 drives the linkage shaft 8 and the rotating plate 801 to rotate, and the rotating plate 801 drives the two counterweight plates 902 to perform circular motion around the axis of the linkage shaft 8, so that it moves to the side away from the linkage shaft 8 under the action of centrifugal force, and drives the cross plate 9 to rotate and move upward at the same time through the corresponding bending rod 901. The cross plate 9 drives the connecting plate 13 to move upward synchronously through the cooperation with the connecting column 11 and the limiting shaft sleeve 12, and the upward movement distance of the two connecting plates 13 is positively correlated with the power of the corresponding water pump 7. When the power of one of the water pumps 7 increases, The upward movement distance of the corresponding connecting plate 13 is increased, so that the two connecting plates 13 move up and down relatively, and the corresponding sliding frame 1503 and the pressing plate 15 are driven to move horizontally through the contact between the triangular plate 16 and the corresponding rotating wheel 1504. When the power difference between the two water pumps 7 is large enough, the pressing plate 15 contacts the corresponding control button 14 and controls the corresponding refrigerator 10 to start, thereby cooling the cooling water entering the corresponding water pump 7 to improve its cooling effect, thereby keeping the cooling rate of the inner and outer walls of the molding material consistent, thereby improving the molding quality;

[0074] When the connecting plate 13 moves upward, the square plate 22 is driven upward through the vertical rod 17, squeezing the push plate 20, the compression spring 23 and the varistor 19, causing the compression spring 23 to undergo elastic deformation and reducing the resistance of the corresponding varistor 19. Since the varistor 19 is connected in series with the refrigerator 10, the power of the corresponding refrigerator 10 can be increased when the resistance is reduced, thereby improving the cooling effect, thereby further ensuring uniform cooling of the inner cylinder 302 and the outer cylinder 301.
