Description

Technical Field

[0001] This utility model relates to the technical field of fire hose extrusion molding equipment, specifically to a fire hose extrusion molding linkage device. Background Technology

[0002] TPV high-temperature resistant fire hoses are a new type of fire hose that uses TPV, a novel material blended from ultra-lightweight PP and ultra-fine EPDM powder, as the inner tube material. This technology significantly improves upon the shortcomings of traditional PVC fire hoses, such as easy breakage at low temperatures, poor elasticity, and insufficient high-temperature resistance. It also addresses the environmental pollution, complex processing, high material density, and heavy weight of traditional rubber hoses. Patent CN201920777175.1 discloses a one-time extrusion molding device for TPV high-temperature resistant fire hoses. By setting a first cooling device on the outside of the extrusion die, the extruded fire hose can be cooled and shaped in time. A second cooling device further cools the hose, and a limiting roller flattens the hose for easy subsequent winding and packaging. However, during the winding process using a roller to rewind the extruded fire hose, and especially when it reaches a certain length, workers need to use a blade to cut it, which is inconvenient. Therefore, we propose a fire hose extrusion molding linkage device. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a fire hose extrusion molding linkage device.

[0004] The technical solution adopted by this utility model to solve its technical problem is a fire hose extrusion molding linkage device, including a base, an extruder body and a support are assembled on the top surface of the base, and straight arms for support are bolted to the outer wall surface of the support. There are two sets of straight arms, and a meter counter is assembled on the outer wall surface of the straight arms. A rotating roller connected to the power output end of the meter counter is rotatably installed between the two sets of straight arms.

[0005] A U-shaped frame for support is assembled between the two sets of straight arms, and a pressure plate for limiting is slidably installed inside the U-shaped frame. An electric push rod for pushing the pressure plate is assembled on the top surface of the U-shaped frame, and there are two sets of electric push rods. A rail seat corresponding to the pressure plate is assembled between the two sets of straight arms, and an adjustable slide is slidably installed inside the rail seat. A cutting blade is assembled on the outer wall surface of the slide by screws.

[0006] By adopting the above technical solution, during the use of the fire hose extrusion molding equipment, the fire hose can pass through the top of the rotating roller after being extruded and cooled by the main body of the extruder. When passing through, it is convenient to drive the rotating roller to rotate. The meter counter on the outer periphery of the straight arm can count according to the number of rotations of the rotating roller, which is convenient for measuring the length of the roll, so that the personnel can clearly understand the specific length of the roll.

[0007] When the winding length reaches the set length, the electric push rod at the top of the U-shaped frame can be operated under the control of the controller to push the pressure plate down. The pressure plate and the rail seats between the two sets of straight arms cooperate to press and fix the fire hose. Then, the slide inside the rail seat slides along the rail seat, and the slide seat can easily drive the blade to cut the fire hose. This makes it easy for personnel to take out the fire hose after winding and replace the empty roller to continue winding the fire hose. The automatic cutting method is more convenient. At the same time, it can be linked with the metering structure so that the extrusion molding equipment can not only measure the winding length, but also cut it when the winding length reaches the standard, which is convenient for storage.

[0008] Specifically, a lead screw that is screwed into the slide is rotatably installed inside the rail base, and a reducer that is driven by the lead screw is mounted on the outer wall surface of the rail base. A servo motor is mounted on the power input end of the reducer.

[0009] By adopting the above technical solution, the servo motor can easily rotate the lead screw in the rail seat under the operation of the reducer, so that the lead screw can be screwed into the sliding carriage in the rail seat. Under the screwing force, the carriage slides and moves along the rail seat, and then the carriage can drive the blade to cut the fire hose.

[0010] Specifically, a roller for winding fire hose is rotatably installed on the inner side of the bracket, and a drive motor for driving the roller to rotate is mounted on the outer wall surface of the bracket.

[0011] By adopting the above technical solution, the drive motor on the outside of the bracket can easily drive the roller to rotate, so that the roller can rewind the fire hose after it has been extruded and cooled.

[0012] Specifically, the top surface of the base is fitted with a groove located between the support and the extruder body.

[0013] By adopting the above technical solution, the ice water filled in the tank can effectively cool the extruded fire hose, making it easier to rewind it later.

[0014] Specifically, the outer wall surface of the straight arm is equipped with a controller that is electrically connected to the meter counter, the electric push rod, and the servo motor.

[0015] By adopting the above technical solution, the controller can easily control the operation of the meter counter, electric push rod and servo motor, so that the three can work together under the operation of the PLC system inside the controller, which facilitates the measurement, clamping and cutting of fire hoses.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of the extruder body, support, straight arm, meter counter and rotating roller, allows the fire hose to pass through the top of the rotating roller after being extruded and cooled by the extruder body during the use of the fire hose extrusion molding equipment. This facilitates the rotation of the rotating roller during the passage. The meter counter on the outer periphery of the straight arm can count the number of rotations of the rotating roller, making it convenient to measure the winding length and allowing personnel to clearly understand the specific winding length.

[0018] 2. The technical solution of this application, through the design of the U-shaped frame, pressure plate, electric push rod, rail seat, slide, and blade body, allows the electric push rod at the top of the U-shaped frame to operate and push the pressure plate down under the control of the controller when the winding length reaches the set length. The rail seat between the pressure plate and the two sets of straight arms cooperates to facilitate the clamping and fixing of the fire hose. Then, the slide inside the rail seat slides along the rail seat, and the slide seat easily drives the blade body to cut the fire hose. This makes it convenient for personnel to take out the fire hose after winding and replace the empty roller to continue winding the fire hose. The automatic cutting method is more convenient. At the same time, it can be linked with the metering structure so that the extrusion molding equipment can not only measure the winding length, but also cut it when the winding length reaches the standard, which is convenient for storage.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a fire hose extrusion molding linkage device, including a base 1, an extruder body 2 and a support 4 mounted on the top surface of the base 1, straight arms 5 for support mounted on the outer wall surface of the support 4 by bolts, and there are two sets of straight arms 5, a meter counter 6 mounted on the outer wall surface of the straight arms 5, and a rotating roller 7 connected to the power output end of the meter counter 6 is rotatably installed between the two sets of straight arms 5; a U-shaped frame 9 for support is mounted between the two sets of straight arms 5, and a pressure plate 10 for limiting is slidably installed on the inner side of the U-shaped frame 9; an electric push rod 11 for pushing the pressure plate 10 to move is mounted on the top surface of the U-shaped frame 9, and there are two sets of electric push rods 11; a rail seat 12 corresponding to the pressure plate 10 is mounted between the two sets of straight arms 5, and an adjustable slide 13 is slidably installed in the rail seat 12; a cutting blade 14 is mounted on the outer wall surface of the slide 13 by screws.

[0026] During use, when the fire hose is extruded and cooled by the main body 2 of the extruder, it can pass through the top of the rotating roller 7. When passing through, it is convenient to drive the rotating roller 7 to rotate. The meter counter 6 on the outer periphery of the straight arm 5 can count according to the number of rotations of the rotating roller 7, which is convenient for measuring the length of the roll, so that the personnel can clearly understand the specific length of the roll.

[0027] When the winding length reaches the set length, the electric push rod 11 on the top of the U-shaped frame 9 can be operated under the control of the controller 8 to push the pressure plate 10 down. The pressure plate 10 and the rail seat 12 between the two sets of straight arms 5 cooperate to press and fix the fire hose. Then, the slide 13 inside the rail seat 12 slides along the rail seat 12. The slide 13 then drives the blade body 14 to cut the fire hose, making it easy for personnel to take out the fire hose after winding and replace the empty roller 18 to continue winding the fire hose. The automatic cutting method is more convenient. At the same time, it can be linked with the metering structure so that the extrusion molding equipment can not only measure the winding length, but also cut it when the winding length reaches the standard, which is convenient for storage.

[0028] like Figure 3 As shown, a lead screw 15 is rotatably installed inside the rail base 12 and is screwed to the slide 13. A reducer 16 is mounted on the outer wall surface of the rail base 12 and is driven by the lead screw 15. A servo motor 17 is mounted on the power input end of the reducer 16.

[0029] In use, the servo motor 17 operates conveniently, driving the lead screw 15 in the rail seat 12 to rotate under the operation of the reducer 16, so that the lead screw 15 can be screwed into the sliding carriage 13 in the rail seat 12, so that the carriage 13 slides along the rail seat 12 under the screwing force, and then the carriage 13 can drive the blade body 14 to cut the fire hose.

[0030] like Figure 1 and Figure 2 As shown, a roller 18 for winding fire hose is rotatably installed on the inner side of the bracket 4, and a drive motor 19 for driving the roller 18 to rotate is mounted on the outer wall surface of the bracket 4.

[0031] In use, the drive motor 19 on the outside of the bracket 4 can easily drive the roller 18 to rotate, so that the roller 18 can rewind the fire hose after it has been extruded and cooled.

[0032] like Figure 1 As shown, the top surface of the base 1 is fitted with a groove 3 located between the support 4 and the extruder body 2.

[0033] During use, the ice water filled in tank 3 helps to cool the extruded fire hose, making it easier to rewind later.

[0034] like Figure 1 and Figure 2 As shown, the outer wall surface of the straight arm 5 is equipped with a controller 8 that is electrically connected to the meter counter 6, the electric push rod 11, and the servo motor 17.

[0035] In use, the controller 8 can easily control the operation of the meter counter 6, the electric push rod 11 and the servo motor 17, so that the three can work together under the operation of the PLC system inside the controller 8, which facilitates the measurement, clamping and cutting of fire hoses.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the extrusion molding process of the fire hose, after the fire hose is extruded and cooled by the main body 2 of the extruder, it can pass through the top of the rotating roller 7. This facilitates the rotation of the rotating roller 7, and the meter counter 6 on the outer periphery of the straight arm 5 counts the number of rotations of the rotating roller 7, making it convenient to measure the winding length. This allows personnel to clearly understand the specific winding length. Simultaneously, when the winding length reaches the set length, the electric push rod 11 at the top of the U-shaped frame 9 can be operated under the control of the controller 8 to push the pressure plate 10 down. The pressure plate 10 and the rail seat 12 between the two sets of straight arms 5 cooperate to facilitate the insertion of the fire hose. After the hose is pressed and fixed, the servo motor 17 operates to drive the lead screw 15 in the rail seat 12 to rotate under the operation of the reducer 16. This allows the lead screw 15 to engage with the sliding carriage 13 in the rail seat 12. Under the force of the engagement, the carriage 13 slides along the rail seat 12. Subsequently, the carriage 13 drives the blade body 14 to cut the fire hose, making it convenient for personnel to take out the fire hose after it has been wound up and replace the empty roller 18 to continue winding the fire hose. The automatic cutting method is more convenient. At the same time, it can be linked with the metering structure, so that the extrusion molding equipment can not only measure the length of the winding, but also cut it when the winding length reaches the standard, making it convenient to store the molded fire hose.
