[0002] At present, high-temperature resistant rubber tubes are widely used in the petroleum and chemical industries due to their good heat resistance. The manufacturing process of high-temperature resistant rubber tubes has relatively high requirements. After vulcanization, the rubber tubes need to go through processes such as cooling, winding, and cutting. The cooling time is long, the production process is not continuous, and there are bubbles after vulcanization. The air-expansion shaft for winding needs to make a full circle before it can continue, resulting in low efficiency and wasting a large amount of labor. Summary of the Invention

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A high-temperature resistant rubber tube cooling and winding device includes a winding frame, a limiting frame, a cutting machine, a positioning column one, a positioning column two, a fan one, a fan two, and a conveyor belt. The positioning column one and the positioning column two are vertically arranged. There is a support frame above the positioning column one. A fixed roller and a pressing roller are arranged inside the support frame. The fixed roller is connected to a motor one. Above the pressing roller, a V-shaped pressing block and a screw handle are connected. There is a square block on the side of the support frame. A limiting plate is arranged outside the square block. There is a right-angle channel between the square block and the limiting plate. A pressing roller is arranged between the positioning column one and the positioning column two. The conveyor belt is arranged on the right side of the positioning column one. The fan one is arranged at both ends above the conveyor belt. There is a pressing block above the positioning column two. There is an arc groove in the middle of the lower plane of the pressing block. There is a bearing on the upper plane of the positioning column. The bearing is arranged below the pressing block. There are two positioning pins below the pressing block. Two groups of positioning grooves are arranged on the positioning pins. There are two blind holes on the upper plane of the positioning column two. Two groups of spring beads are arranged on the side of the blind holes. The pressing block is inserted into the blind holes through the positioning pins. There is a slide rail on the left side of the positioning column two. The cutting machine is installed on the slide rail. The handle of the cutting machine extends out of the side of the positioning column two. A power switch is arranged on the handle of the cutting machine. The winding frame is located at the left rear end of the positioning column two. There is a track below the winding frame. There is a connecting block on the right side of the winding frame. The right side of the connecting block is connected to the side of the positioning column two through a spring. There is a hollow steel pipe in the middle of the winding frame. The rear end of the hollow steel pipe is connected to a motor two. There is a long slot on the side of the hollow steel pipe. The limiting frame includes a round pipe and a handle in a vertical structure. The round pipe is inserted into the hollow steel pipe. The fan two is arranged on the left side of the winding frame.

[0006] As an improvement of the present invention, the length of the hollow steel pipe is greater than the width of the rubber tube.

[0007] As an improvement of the present invention, a limiting block is provided on the conveyor belt to prevent the rubber tube from shifting.

[0008] As an improvement of the present invention, a length meter is provided on the right side of the second positioning post.

[0009] As an improvement of the present invention, the first motor and the second motor are servo motors.

[0010] As an improvement of the present invention, the first fan is provided in 1 - 4 groups.

[0011] The winding method of the high - temperature resistant rubber tube cooling and winding device of the present invention includes the following steps:

[0012] (1) After the vulcanization of the high - temperature resistant rubber tube is completed, it is placed on the conveyor belt, and a first fan blows against the high - temperature resistant rubber tube above to cool it quickly;

[0013] (2) The high - temperature resistant rubber tube passes through the right - angle channel. When passing through the right - angle turning, the high - temperature resistant rubber tube is pressed, and the internal air bubbles are squeezed out;

[0014] (3) The high - temperature resistant rubber tube passes between the fixed roller and the pressing roller, and then passes through the bearing. At this time, the second set of positioning grooves below the positioning pin are stuck on the first set of spring beads, and there is a gap between the arc groove and the bearing;

[0015] (4) The head of the high - temperature resistant rubber tube is inserted into the hollow steel pipe from the long slot, and the round tube is inserted into the hollow steel pipe to clamp the head of the high - temperature resistant rubber tube;

[0016] (5) Start the first motor and the second motor. The first motor starts to feed forward, and the second motor starts to wind. The handle plays a limiting role to prevent the high - temperature resistant rubber tube from deviating. The length meter starts to count, and the second fan blows against the wound high - temperature resistant rubber tube to cool it again;

[0017] (6) When the winding reaches the predetermined length, the second motor stops, the pressing block presses down, and the first set of positioning grooves below the positioning pin are stuck on the second set of spring beads below, so that the high - temperature resistant rubber tube is clamped between the arc groove and the bearing;

[0018] (7) Start the cutting machine to move upward on the slide rail to cut the high - temperature resistant rubber tube. At this time, the first motor is still working, and the high - temperature resistant rubber tube between the first positioning post and the second positioning post sinks downward under the gravity of the pressing roller;

[0019] (8) Pull out the limit frame, take out the wound rubber tube, and then pull the pressing block up a little so that the second set of positioning grooves below the positioning pin are stuck on the first set of spring beads, and there is a gap between the arc groove and the bearing. Insert the head of the high-temperature resistant rubber tube into the hollow steel pipe through the long slot, and repeat steps (4)-(7), where the rotational speed of motor two is higher than that of motor one, and accelerate the winding of the sunken high-temperature resistant rubber tube between positioning post one and positioning post two. The tightness of the high-temperature resistant rubber tube during the winding process is determined by the moving distance of the winding frame on the track.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) The present invention integrates defoaming, cooling, and winding, with a scientific and practical structure and high working efficiency;

[0022] (2) Before and during winding, fan one and fan two are used to cool the rubber tube in different places, and the cooling effect is obvious;

[0023] (3) Before winding, corner compression defoaming is performed on the rubber tube to improve the quality of the rubber tube;

[0024] (4) The rubber tube that moves forward is measured and cut, and the winding length is accurate;

[0025] (5) The side of the hollow steel pipe is provided with a long slot. The head of the high-temperature resistant rubber tube is inserted into the hollow steel pipe through the long slot. The round tube is inserted into the hollow steel pipe to hold the head of the high-temperature resistant rubber tube and start winding. The material used at the joint is less and the operation is convenient;

[0026] (6) During cutting, it does not affect the continuous forward movement of the rubber tube at the rear end. The high-temperature resistant rubber tube between positioning post one and positioning post two is pressed down by the gravity of the pressing roller. After the next winding starts, make the rotational speed of motor two higher than that of motor one, and accelerate the winding of the sunken high-temperature resistant rubber tube between positioning post one and positioning post two to improve the working efficiency;

[0027] (7) When the rotational speeds of motor two and motor one are different, in order to prevent the wound rubber tube from being too tight, the winding frame can move on the track, and the elastic force of the spring is used to control the moving distance of the winding frame to ensure the tightness of the rubber tube after winding;

[0028] (8) The movement of the rubber tube is controlled by the height of the pressing block. The pressing block has two positions. The first is the working position. At this time, the second set of positioning grooves below the positioning pin are stuck on the first set of spring beads, and there is a gap between the arc groove and the bearing. The high-temperature resistant rubber tube passes through the bearing. The second is the locking position. Press the pressing block down, and the first set of positioning grooves below the positioning pin are stuck on the second set of spring beads below, so that the high-temperature resistant rubber tube is stuck between the arc groove and the bearing, which is convenient for cutting the rubber tube; these two positions are operated conveniently through the cooperation of the positioning grooves and the spring beads;

[0029] (9) The cutting machine is installed on the slide rail, and the handle of the cutting machine extends out of the side of the second positioning post, which is convenient to use;

[0030] (10) The handle plays a limiting role to prevent the high-temperature resistant rubber hose from deviating outwards. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Its working principle is:

[0041] (1) After the high-temperature resistant rubber tube 38 is vulcanized, it is placed on the conveyor belt 8. There are limiting blocks 36 on the conveyor belt to prevent the rubber tube from shifting. Above, there is a fan 1 6 (two groups of four fans) blowing against the high-temperature resistant rubber tube 38 to make it cool down quickly.

[0042] (2) The high-temperature resistant rubber tube 38 passes through the right-angle channel 16. When passing through the right-angle bend, the high-temperature resistant rubber tube 38 is pressed, and the air bubbles inside are squeezed out, as Figure 5 shown.

[0043] (3) The high-temperature resistant rubber tube 38 passes through between the fixed roller 10 and the pressing roller 11, and then passes through the bearing 20. At this time, the second set of positioning grooves below the positioning pin 21 are stuck on the first set of spring beads, and there is a gap between the arc groove 19 and the bearing 20, as shown in Figure 4 as shown in b;

[0044] (4) The head of the high-temperature resistant rubber tube 38 is inserted into the hollow steel tube from the long slot (the length of the hollow steel tube 31 is greater than the width of the rubber tube 38), as shown in Figure 3 shown in the figure, and the round tube 34 is inserted into the hollow steel tube 31 to clamp the head of the high-temperature resistant rubber tube;

[0045] (5) Start the first motor 39 and the second motor 32. The first motor 39 starts to feed forward, and the second motor 32 starts to wind. The handle plays a limiting role to prevent the high-temperature resistant rubber tube 38 from deviating. The meter counter starts to count, and the second fan 7 blows on the wound high-temperature resistant rubber tube 38 to cool it down again;

[0046] (6) When the winding reaches the predetermined length, the second motor 32 stops, and the pressing block 18 presses down. The first set of positioning grooves below the positioning pin 21 are stuck on the second set of spring beads below, so that the high-temperature resistant rubber tube is stuck between the arc groove 19 and the bearing 20, as shown in Figure 4 as shown in c;

[0047] (7) Start the cutting machine 3 to move upward on the slide rail 25 to cut the high-temperature resistant rubber tube. At this time, the first motor is still working, and the high-temperature resistant rubber tube 38 between the first positioning column and the second positioning column sinks downward under the gravity of the pressing roller 17;

[0048] (8) Pull out the limit frame, take out the wound rubber tube, and then pull the pressing block 18 up a little so that the second set of positioning grooves below the positioning pin 21 are stuck on the first set of spring beads, as shown in Figure 4 as shown in b, there is a gap between the arc groove 19 and the bearing 20. Insert the head of the high-temperature resistant rubber tube into the hollow steel tube from the long slot, and repeat steps (4)-(7). The rotation speed of the second motor is higher than that of the first motor (the first motor 39 and the second motor 32 are servo motors), and the sunken high-temperature resistant rubber tube 38 between the first positioning column and the second positioning column is accelerated and wound. The tightness of the high-temperature resistant rubber tube 38 during the winding process is determined by the distance that the winding frame 1 moves on the track 28.
