Description

Technical Field

[0001] This invention relates to the field of hose manufacturing technology, and in particular to a rapid cooling process and equipment for hoses. Background Technology

[0002] Traditional extruder cooling water tanks are usually installed on the ground or on a bracket. The extruded plastic strips are cooled and shaped in the water tank.

[0003] Chinese patent CN210525801U discloses a high-efficiency cooling and drying water tank for a plastic extruder, including a tank body and a frame. A support roller shaft and a pressure roller shaft are fixed to the side wall of the tank body. A drying nozzle is provided on one side of the tank body, and the drying nozzle is connected to a fan via an air duct. This solution achieves cooling of the plastic strips produced by the extruder. The cooling water tank is equipped with a drying and air-cooling device, which further cools the plastic strips while drying the moisture remaining on them after cooling in the water tank. The support roller shaft and pressure roller shaft are fixed by screwing, eliminating the need for drilling holes in the water tank, allowing for installation at any position on the water tank and stepless adjustment of the installation height.

[0004] The above-mentioned device cools long, hot materials by using a water tank. However, in actual use, the temperature of the cooling water around the hot material is high, while the temperature of the coolant inside and outside the water tank is low. During the cooling water circulation process, the coolant inside the water tank is also discharged, resulting in insufficient utilization of the cooling water. In summary, the above-mentioned device still has room for improvement.

[0005] Therefore, it is necessary to provide a rapid cooling process and equipment for hoses to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a rapid cooling process and equipment for hoses, in order to solve the problem mentioned in the background art that the existing device cools long strip-shaped hot materials by setting up a water tank. However, in actual use, the temperature of the cooling water around the hot material is high, while the temperature of the coolant inside and outside the water tank is low. During the cooling water circulation process, the coolant with a lower temperature inside the water tank is also discharged, resulting in insufficient utilization of the cooling water.

[0007] Based on the above ideas, the present invention provides the following technical solution: including a water tank, with a first guide roller and a second guide roller respectively arranged at both ends inside the water tank, chains arranged on both sides inside the water tank, an outer frame arranged on the outer side of the chains, a support roller arranged between the two chains, a baffle arranged on the inner side of the chains, the baffle being connected to the chains through a fixing block, and an arc surface arranged on the side of the baffle away from the fixing block;

[0008] The top and bottom of the fixed block are both fixedly provided with upright plates, and limit components are slidably provided on the upright plates. The inner side of the outer frame is provided with a guide component that cooperates with the limit component. When the chain drives the baffle to move to the guide component, the limit component can slide relative to the upright plate as it moves along the guide component, thereby driving the baffle to rotate to a state perpendicular to the chain through the limit component.

[0009] As a further embodiment of the present invention: the limiting component includes a slider, the upright plate has a through groove, the slider is slidably disposed in the groove, and a limiting block is fixedly connected to the side of the slider near the baffle. A guide shaft is fixedly connected in the groove, the guide shaft passes through the slider and is slidably connected to it, and a spring is sleeved on the outside of the guide shaft. The spring is disposed above the slider and between the slider and the end face of the groove.

[0010] As a further embodiment of the present invention: two connecting columns are fixedly provided on one side of the baffle near the fixing block, and a spiral first limiting groove is provided on the outer circumferential surface of the two connecting columns. The limiting block is slidably disposed in the first limiting groove. A round shaft is fixedly connected between the two connecting columns. A boss is fixedly provided on one side of the fixing block near the baffle. A through round hole is provided on the boss. The round shaft passes through the round hole and is rotatably connected to the boss.

[0011] As a further aspect of the present invention: the guide assembly includes a limiting rod, the number of the limiting rods is set to multiple, and two adjacent limiting rods are set as a group. The limiting rod is composed of a parallel segment and an inclined segment. A guide groove is formed between the parallel segments of two adjacent limiting rods, and a second limiting groove is formed between the inclined segments of two adjacent limiting rods.

[0012] As a further aspect of the present invention: a protruding strip is fixedly connected to the inner side of the outer frame, and a groove for accommodating the chain is formed between the protruding strip and the outer frame. Both ends of the outer frame are provided with sprockets, the chain is sleeved between the two sprockets, and a horizontal shaft is provided between two adjacent sprockets.

[0013] As a further aspect of the present invention, an inlet pipe and an outlet pipe are respectively provided at both ends of the water tank.

[0014] As a further embodiment of the present invention: a pressure plate is provided at the end of the baffle away from the fixed block, and a telescopic cover is fixedly provided between the pressure plate and the end face of the baffle. An arc-shaped groove is provided on the arc surface of the baffle, and an airbag is provided in the arc-shaped groove. The airbag is bonded to the inner bottom surface of the arc-shaped groove. A flow guiding channel is provided at the end of the baffle. One end of the flow guiding channel is connected to the telescopic cover, and the other end of the flow guiding channel is connected to the airbag.

[0015] As a further aspect of the present invention: the side of the upright plate closest to the baffle is arc-shaped.

[0016] As a further aspect of the present invention: the two sets of limiting rods on the inner side of the outer frame are fixedly connected to the outer frame and the protrusion strip through the bracket.

[0017] A process for rapid cooling using the hose rapid cooling equipment described above includes the following steps:

[0018] S1. The baffle moves by the chain. When the vertical plate on the fixed block gradually moves to the limit rod, the baffle rotates to the vertical position. Then, as the chain continues to move, the slider is limited by the second limit groove, so that the slider can move upward relative to the vertical plate during the process of the vertical plate moving the slider along the horizontal plane, thereby driving the connecting column and the baffle to rotate inward, so that the two baffles are attached and wrapped around the outside of the rubber tube.

[0019] S2. When the baffle moves with the chain to the vicinity of the right end of the water tank, the slider moves out from between the two adjacent limit rods. The spring can drive the slider to move downward relative to the vertical plate and reset. During this process, the limit block will move downward along the first limit groove and drive the baffle to rotate outward.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: This device, through the cooperation of the limiting component and the guiding component, allows the baffle to rotate inward and be in a collinear state when it moves with the chain to the limiting rod. When the two baffles are in contact, a hole is formed between the two baffles that matches the hose, so that the baffle can better wrap around the outside of the hose. Subsequently, as the baffle continues to move with the chain, it can accelerate the flow rate of the cooling water around the hose, thereby allowing the cooler cooling water from the outside to flow to the hose, which is beneficial to improving the cooling effect on the hose and making full use of the cooling water.

[0033] like Figure 1-4 As shown, a hose rapid cooling process and rapid cooling equipment includes a water tank 1. The two ends of the water tank 1 are respectively connected to an inlet pipe and an outlet pipe. The two ends inside the water tank 1 are respectively provided with a first guide roller 5 and a second guide roller 2. The first guide roller 5 and the second guide roller 2 are rotatably connected to the water tank 1.

[0034] To support the hose and ensure its stable movement within the water tank 1, chains 11 are arranged on both sides inside the water tank 1. An outer frame 4 is provided on the outer side of each chain 11, and a support roller 9 is provided between the two chains 11. In actual use, the hose passes under the first guide roller 5 and the second guide roller 2 and falls onto the support roller 9 between the two chains 11. Cooling water is injected into the water tank 1 through the water inlet pipe. As the chains 11 move, the support roller 9 assists in moving the hose, thereby cooling it down. The water outlet pipe facilitates the discharge of the cooling water from the water tank 1, thus achieving water circulation.

[0035] A baffle 7 is provided on the inner side of the chain 11. The baffle 7 is connected to the chain 11 through a fixing block 8, and the side of the baffle 7 away from the fixing block 8 is provided with an arc surface. When the two baffles 7 rotate to a collinear state, they can wrap around the outside of the rubber tube. The top and bottom of the fixing block 8 are fixedly provided with upright plates 12. A limit component is slidably provided on the upright plate 12. A guide component that cooperates with the limit component is provided on the inner side of the outer frame 4. In actual use, when the chain 11 drives the baffle 7 to move to the guide component, the limit component can slide vertically relative to the upright plate 12 during the movement along the guide component. During this process, the limit component drives the baffle 7 to rotate to a state perpendicular to the chain 11, so that the two baffles 7 can stick to each other and wrap around the outside of the rubber tube. At this time, when the chain 11 moves, the two baffles 7 can move along the outside of the rubber tube, thereby accelerating the flow rate of the cooling water around the rubber tube, so that the outer cooling water can flow to the outside of the rubber tube to cool it down.

[0036] like Figure 2-6 As shown in Figures 8 and 9, the limiting component includes a slider 15. A through groove is provided on the upright plate 12. The slider 15 is slidably disposed in the groove, and a limiting block 14 is fixedly connected to the side of the slider 15 near the baffle 7.

[0037] A guide shaft 27 is fixedly connected inside the groove. The guide shaft 27 passes through the slider 15 and is slidably connected to it. A spring 26 is sleeved on the outside of the guide shaft 27. The spring 26 is located above the slider 15 and between the slider 15 and the end face of the groove.

[0038] To cooperate with the limiting block 14, two connecting posts 16 are fixedly installed on the side of the baffle 7 near the fixing block 8. A spiral first limiting groove 17 is opened on the outer circumferential surface of the two connecting posts 16. The limiting block 14 is slidably installed in the first limiting groove 17. A round shaft 18 is fixedly connected between the two connecting posts 16. A boss 13 is fixedly installed on the side of the fixing block 8 near the baffle 7. A through round hole is opened on the boss 13. The round shaft 18 passes through the round hole and is rotatably connected to the boss 13. The boss 13 is placed between the upper and lower connecting posts 16.

[0039] The guiding assembly includes limiting rods 3, and the number of limiting rods 3 is set to multiple, with adjacent limiting rods 3 forming a group. Each limiting rod 3 consists of a parallel section and an inclined section. A guide groove 24 is formed between the parallel sections of adjacent limiting rods 3, and a second limiting groove 22 is formed between the inclined sections of adjacent limiting rods 3. In addition, an opening 23 is formed at the end of adjacent limiting rods 3 away from the guide groove 24, so that the limiting block 14 can enter between the two limiting rods 3 through this opening 23. In actual use, one end of the slider 15 passes through the sliding groove and can extend to the space between adjacent limiting rods 3. When the two upright plates 12 rotate to a vertical state with the chain 11, the limiting block 14 on the upright plate 12 can enter between the two limiting rods 3 along the opening 23. Two sets of limiting rods 3 are provided on the inner side of the outer frame 4, corresponding to the upper and lower upright plates 12 of the fixing block 8, respectively.

[0040] In actual use, the chain 11 can synchronously drive the baffle 7 to move. When the baffle 7 moves to the left end with the chain 11, the two baffles 7 can pass through the outside of the rubber tube without interfering with it. When the vertical plate 12 on the fixed block 8 gradually moves to the limiting rod 3, the baffle 7 rotates to a vertical state. Then, as the chain 11 continues to move, one end of the slider 15 on the vertical plate 12 moves to the opening 23, thus entering the second limiting groove 22 between the two adjacent limiting rods 3 through the opening 23. The second limiting groove 22 limits the slider 15, so that as the vertical plate 12 drives the slider 15 to move along the horizontal plane, the slider 15 can move upward relative to the vertical plate 12. The limiting block 14 at the end slides into the first limiting groove 17. Therefore, when the slider 15 moves upward, the limiting block 14 will move upward along the first limiting groove 17, thereby driving the connecting column 16 and the baffle 7 to rotate inward. When the slider 15 moves from the second limiting groove 22 to the guide groove 24, the two baffles 7 rotate to a collinear state and fit together. Since the side of the baffle 7 away from the fixed block 8 is provided with an arc surface, when the two baffles 7 fit together, they can wrap around the outside of the rubber tube. At this time, when the chain 11 continues to drive the baffle 7 to move outside the rubber tube, it can accelerate the flow of cooling water around the rubber tube, thereby allowing the cooler cooling water in the outer periphery to flow around the rubber tube, which is beneficial to improving the cooling effect of the rubber tube.

[0041] When the baffle 7 moves with the chain 11 to near the right end of the water tank 1, the slider 15 moves out from between the two adjacent limiting rods 3. At this time, the spring 26 can drive the slider 15 to move downward relative to the vertical plate 12 and reset. During this process, the limiting block 14 will move downward along the first limiting groove 17 and drive the baffle 7 to rotate outward. When the two baffles 7 rotate outward and open, they can pass through the outside of the rubber tube without interfering with the rubber tube, which is conducive to the baffle 7 moving with the chain 11 to the bottom of the water tank 1. Repeating the above operation can drive the baffle 7 to periodically wrap around the outside of the rubber tube and move relative to the rubber tube, which is conducive to accelerating the flow of cooling water around the rubber tube.

[0042] In summary, this device, through the cooperation of the limiting component and the guiding component, allows the baffle 7 to rotate inward and become collinear when it moves with the chain 11 to the limiting rod 3. When the two baffles 7 are in contact, a hole is formed between them that matches the hose, allowing the baffle 7 to better wrap around the outside of the hose. Subsequently, as the baffle 7 continues to move with the chain 11, it can accelerate the flow rate of the cooling water around the hose, thereby allowing the cooler cooling water to flow to the hose, which is beneficial to improving the cooling effect on the hose and making full use of the cooling water.

[0043] In practical use, the chain 11 is composed of a sleeve, a pin, and a chain plate, while the support roller 9 rotates with the pin on the chain 11. In actual applications, a clamp can also be installed on the pin so that the support roller 9 is connected to the clamp. The fixing block 8 can be fixedly connected to the two pins on the chain plate. Of course, installing a rigid component on the chain 11 is a mature technical means in the mechanical field, which will not be elaborated here.

[0044] like Figure 7 , 9 As shown in Figure -10, a pressure plate 20 is provided at the end of the baffle 7 away from the fixed block 8. A telescopic cover 19 is fixedly provided between the pressure plate 20 and the end face of the baffle 7. An arc-shaped groove is provided on the arc surface of the baffle 7, and an airbag 25 is provided in the arc-shaped groove. The airbag 25 is bonded to the inner bottom surface of the arc-shaped groove. A flow guide channel 21 is provided at the end of the baffle 7. One end of the flow guide channel 21 is connected to the telescopic cover 19. A flow guide tube is installed on the airbag 25. The end of the flow guide tube away from the airbag 25 extends to the other end of the flow guide channel 21 and is fixedly connected to the baffle 7.

[0045] In actual use, when the two baffles 7 rotate inward and gradually come together, the pressure plates 20 on the two baffles 7 will gradually come together and squeeze, thereby squeezing the telescopic shield 19. This helps to squeeze the gas in the telescopic shield 19 into the airbag 25 through the guide channel 21, thus increasing the volume of the airbag 25. At this time, the airbag 25 will expand outward through the arc groove and contact the outer wall of the hose. This allows the baffles 7 to remove the water film on the outer wall of the hose as it moves with the chain 11. Furthermore, the close contact between the airbag 25 and the hose helps to further squeeze the cool water with a higher temperature on the outside of the hose to the surrounding area.

[0046] like Figure 1-4 As shown, in order to drive the chain 11 to move, a protruding strip 10 is fixedly connected to the inner side of the outer frame 4. A groove for accommodating the chain 11 is formed between the protruding strip 10 and the outer frame 4. Sprockets are provided at both ends of the outer frame 4, so that the chain 11 is sleeved between the two sprockets. A horizontal shaft is provided between two adjacent sprockets, which passes through the sprockets and is fixedly connected to them. The horizontal shaft passes through the outer frame 4 and is rotatably connected to it. The bottom of the outer frame 4 is fixedly connected to the water tank 1 through the base.

[0047] A motor 6 is fixedly installed on the outside of the water tank 1. The output shaft of the motor 6 is connected to a rotating shaft. The rotating shaft passes through the water tank 1 and is fixedly connected to the horizontal shaft. The rotating shaft is rotatably connected to the water tank 1. This structure enables the motor 6 to drive the sprocket to rotate, which in turn drives the chain 11 to rotate.

[0048] like Figure 1-5 As shown in Figures 7 and 8, the side of the upright plate 12 closest to the baffle 7 is arc-shaped, which allows the upright plate 12 and the connecting column 16 to fit stably together.

[0049] The two sets of limiting rods 3 on the inner side of the outer frame 4 are fixedly connected to the outer frame 4 and the protrusion 10 through the bracket, so as to facilitate the installation of the limiting rods 3.

[0050] In actual use, a support spring 26 can be fixed between the pressure plate 20 and the end of the baffle 7. This will help support the pressure plate 20 and also help the pressure plate 20 to reset.
