Description

[0002] After the heat insulation strip is extruded by the screw extruder, in order to reduce deformation, ensure product quality, prevent distortion and maintain precision, accelerate production process, and reduce the waste rate, cooling treatment is usually required. At present, the commonly used cooling method is to use a cooling water tank. Specifically, after the heat insulation strip is formed, it is sent into the cooling water tank for cooling treatment. The water in the cooling water tank can quickly take away the heat on the heat insulation strip, so that the heat insulation strip is quickly cooled and solidified.

By using the nozzle, first guide groove, second guide groove and third guide groove, the heat insulation strip is prevented from deviating from the transmission route and accumulating. The heat insulation strip is supported by the support plate to avoid up and down fluctuations after being washed. The filtered cartridge filters the wastewater after spraying, thereby saving water resources.

[0004] However, the above cooling device has a complex structure, requires multiple components such as nozzles, guide grooves, support plates, and filter barrels, resulting in increased costs. Furthermore, the above cooling device mainly relies on the rotation of the conveying roller to move the heat insulation strip. When the heat insulation strip passes through the cooling box, it is subjected to the buoyancy of the cooling liquid in the cooling box, which limits the friction between the conveying roller and the heat insulation strip, making it difficult to achieve stable transmission of the heat insulation strip. In addition, the movement path of the heat insulation strip in the cooling box is mainly horizontal and linear, which limits the contact area and contact time of the heat insulation strip with the cooling liquid, reducing the heat exchange and cooling effect of the heat insulation strip. After long-term use, the temperature of the cooling liquid in the cooling box increases, reducing the temperature difference between the cooling liquid and the heat insulation strip, thereby affecting the cooling effect of the heat insulation strip.

[0037] In this utility model, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0038] First Embodiment

[0039] like Figures 1-10 As shown, the cooling device for the rubber heat insulation strip in the first embodiment of this utility model includes:

[0040] Cooling pool 1, with its top open;

[0041] Positioning component 2, there are two positioning components in the cooling pool 1, namely the lower bearing component 3 and the upper limit component 4 which is located directly above the lower bearing component 3. A transmission gap is provided between the lower bearing component 3 and the upper limit component 4 for the rubber heat insulation strip to pass through.

[0042] Transmission component 5 is used to drive the rubber heat insulation strip through the transmission gap along the length direction of the transmission gap.

[0043] The cooling tank 1 in this device is mainly used to store coolant, which is usually cooling water. The cooling tank 1 is a horizontal cuboid. The two positioning components 2 in the cooling tank 1 are located at the lower bearing component 3 and the upper limit component 4, respectively, forming a transmission gap between them for the rubber heat insulation strip extruded by the screw extruder to pass through. When the rubber heat insulation strip passes through the transmission gap, the bottom surface of the rubber heat insulation strip contacts the lower bearing component 3, while the top surface contacts the upper limit component 4. That is, the transmission trajectory of the rubber heat insulation strip through the cooling tank 1 is limited by the lower bearing component 3 and the upper limit component 4, and the transmission component 5 provides the power for the rubber heat insulation strip to move. In this way, the stable transmission of the rubber heat insulation strip in the cooling tank 1 is achieved.

[0044] When the rubber heat insulation strip passes through the cooling pool 1, it comes into contact with the coolant in the cooling pool 1. The coolant absorbs the heat from the rubber heat insulation strip, thereby achieving the cooling and temperature reduction treatment of the rubber heat insulation strip.

[0045] In this device, the transmission trajectory of the rubber heat insulation strip can be limited by the lower bearing component 3 and the upper limit component 4, and the transmission component 5 provides the transmission power for the rubber heat insulation strip, which makes the device structure simple and reduces the cooling process cost.

[0046] Further improvement is that the extension trajectory of the transmission gap is a broken line. By limiting the trajectory of the transmission gap as a broken line, the transmission trajectory length of the rubber heat insulation strip in the cooling pool 1 is extended, the contact area of the rubber heat insulation strip and the cooling liquid in the cooling pool 1 is increased, the contact time of the rubber heat insulation strip and the cooling liquid in the cooling pool 1 is increased under the same transmission speed, and the cooling liquid absorbs the heat of the rubber heat insulation strip. Compared with the horizontal transmission trajectory of the rubber heat insulation strip, the cooling and cooling effect of the rubber heat insulation strip can be further improved.

[0047] Further improvement is that each positioning assembly 2 includes a frame body 21 and a rolling unit 22 arranged on the frame body 21, the rolling unit 22 includes rollers 221 arranged in proximity and distributed along the extension direction of the transmission gap, the axis of the roller 221 extends along the horizontal direction perpendicular to the extension direction of the transmission gap, and the roller 221 rotates on the frame body 21 around its axis; The rolling unit 22 is provided with at least two, which are distributed along the axis of the roller 221 and spaced apart, and a partition 23 is arranged between adjacent rolling units 22; In the lower bearing assembly 3, the top surface of the partition 23 is located above the side of the roller 221, and in the upper limiting assembly 4, the bottom surface of the partition 23 is located below the side of the roller 221.

[0048] The frame body 21 in the lower bearing assembly 3 and the frame body 21 in the upper limiting assembly 4 are the same structure, specifically, as shown in Figures 3-6 The frame body 21 includes two end frames 211 distributed side by side along the width direction of the cooling pool 1, the end frame 211 is a long strip, the shape is consistent with the transmission gap, including a horizontal strip and a inclined strip integrally formed at both ends of the horizontal strip segment, the extension direction of the horizontal strip is consistent with the length direction of the cooling pool 1, and the inclined strips at both ends of the horizontal strip are both inclined and arranged upward. The two end frames 211 are fixedly connected through horizontal shafts 212 distributed side by side along the extension direction of the transmission gap, and the horizontal shafts 212 are arranged in proximity; The two end frames 211 are provided with partitions 23 distributed side by side along the width direction of the cooling pool 1, the partition 23 is a partition strip, the shape is the same as the end frame 211, and the horizontal shaft 212 is fixedly penetrated through the partition 23; The end frame 211 and the partition 23 are provided with rollers 221, and the roller 221 is sealingly sleeved on the horizontal shaft 212, so that the roller 221 can rotate on the frame body 21 around the axis of the horizontal shaft 212; The width of the end frame 211 and the partition 23 is greater than the outer diameter of the roller 221, so that the roller 221 is located between the plane where the top surface of the partition 23 is located and the plane where the bottom surface of the partition 23 is located.

[0049] With the above structure, when the rubber heat insulation strip passes through the transmission gap of the lower bearing assembly 3 and the upper limiting assembly 4, the top surface of the rubber heat insulation strip is in contact with the roller 221 in the upper limiting assembly 4, and the bottom surface is in contact with the roller 221 in the lower bearing assembly 3. The rollers 221 on the upper and lower sides rotate around their own axial lines, which reduces the frictional resistance of the rubber heat insulation strip during transmission while ensuring stable transmission of the rubber heat insulation strip. In addition, by arranging the partition 23, the partition 23 can separate the adjacent two transmission gaps to prevent the rubber heat insulation strips from crossing and winding or abutting, thereby facilitating the stable transmission of the rubber heat insulation strips.

[0050] Further improvement is that it also includes a distance adjusting assembly 6 for adjusting the distance between the lower bearing assembly 3 and the upper limiting assembly 4 to adjust the width of the transmission gap.

[0051] The distance between the lower bearing assembly 3 and the upper limiting assembly 4 can be adjusted by the distance adjusting assembly 6, thereby adjusting the width of the transmission gap to adapt to rubber heat insulation strips of different widths or thicknesses. When the transmission gap is too wide, it affects the stable transmission of the rubber heat insulation strip, and when the transmission gap is too narrow, the pressure of the upper limiting assembly 4 and the lower bearing assembly 3 on the rubber heat insulation strip is too large, which increases the friction of the rubber heat insulation strip during transmission.

[0052] Further improvement is that the output end of the distance adjusting assembly 6 is connected with the upper limiting assembly 4, and the frame body 21 of the lower bearing assembly 3 is fixed in the cooling pool 1.

[0053] Specifically, as shown in Figures 3-6 、 Figure 9 and Figure 10 , the end frame 211 of the frame body 21 in the lower bearing assembly 3 is fixed to the pool bottom of the cooling pool 1 by the vertical rod 24, and the top frame 25 is fixed and connected to the upper side of the end frame 211 of the frame body 21 of the upper limiting assembly 4 by the vertical rod 24. The vertical rod 24 in the two positioning assemblies 2 extends in the vertical direction, and six vertical rods 24 are arranged respectively on the horizontal bars and the two inclined bars of the two end frames 211.

[0054] The distance adjusting assembly 6 includes a U-shaped distance adjusting frame 61, a horizontal flange 15 is fixed to the outer side of the top circumferential edge of the cooling pool 1, and the two ends of the distance adjusting frame 61 are fixed above the flange 15. A downward adjusting motor 62 is fixed above the distance adjusting frame 61, the output end of the adjusting motor 62 is coaxially fixed with a screw rod 63, the screw rod 63 is threadedly connected with a screw sleeve 64, the screw sleeve 64 is fixedly connected with the top frame 25 through a connecting frame 66, and the distance adjusting assembly 6 further includes a sliding sleeve 65 fixed to the inner walls of the two sides of the cooling pool 1 and extending in the vertical direction. Two vertical rods 24 are slidably arranged in the inner side of the sliding sleeve 65.

[0055] With the above structure, the motor 62 drives the screw rod 63 to rotate and act on the screw sleeve 64. Under the sliding cooperation of the vertical rod 24 and the sliding sleeve 65, the connecting frame 66 drives the top frame 25 to move in the vertical direction, and the top frame 25 drives the end frame 211 to move in the vertical direction through the vertical rod 24, so as to adjust the position of the frame body 21, and then change the height position adjustment of the upper limiting assembly 4, thereby realizing the width adjustment function of the transmission gap.

[0056] Further improvement is that the transmission assembly 5 is arranged at the feeding end and / or discharging end of the transmission gap, and the transmission assembly 5 includes two compression rollers respectively arranged on the upper and lower sides of the transmission path of the heat insulation strip and having the axis line extending in parallel to the roller 221 in the axial direction. At least one compression roller is connected with the rotating unit 52, and the rotating unit 52 is used to drive the compression roller to rotate around the axis line thereof.

[0057] In order to further ensure the stable transmission of the rubber heat insulation strip, two transmission assemblies 5 are arranged above the two ends of the flange 15 of the cooling pool 1. The transmission assembly 5 at the feeding side delivers the rubber heat insulation strip into the transmission gap of the cooling pool 1, and the transmission assembly 5 at the discharging side draws the rubber heat insulation strip out of the transmission gap. Through the cooperation of the two ends, the stable transmission of the rubber heat insulation strip is realized.

[0058] Further improvement is that the two compression rollers are a lower compression roller 54 and an upper compression roller 53 arranged directly above the lower compression roller 54. The output end of the rotating unit 52 is connected with the lower compression roller 54. The transmission assembly 5 further includes a transmission frame 51 arranged above the cooling pool 1 and a sliding block 55 sliding on the transmission frame 51 in the vertical direction and rotationally connected with the upper compression roller 53.

[0059] The specific structure of the transmission assembly 5 is shown in Figure 7 and Figure 8 The transmission assembly 5 includes two transmission frames 51 distributed along the width direction of the cooling pool 1 and a rotating unit 52. The rotating unit 52 is a rotating motor. The rotating motor and the two transmission frames 51 are both fixed above the flange 15. The upper compression roller 53 and the lower compression roller 54 are both arranged between the two transmission frames 51 and distributed in the vertical direction. The output end of the rotating motor is fixedly connected with the lower compression roller 54 in the coaxial direction. The two ends of the upper compression roller 53 are rotationally connected with the sliding block 55. The transmission frame 51 is provided with a sliding opening 511 extending in the vertical direction, and the sliding block 55 slides in the inner side of the sliding opening 511. The upper compression roller 53 and the lower compression roller 54 are both provided with a convex ring 56 corresponding to the partition piece 23 and distributed equidistantly in the axial direction.

[0060] With the above structure, the upper pressing roller 53 relies on its own gravity to make the sliding block 55 slide downward along the sliding groove 511, thereby reducing the distance between the upper pressing roller 53 and the lower pressing roller 54, and the rubber heat insulation strip passes between the upper pressing roller 53 and the lower pressing roller 54, and the rubber heat insulation strip is separated by the convex ring 56, and after the rotating unit 52 drives the lower pressing roller 54 to rotate, the upper pressing roller 53 and the lower pressing roller 54 respectively contact the top surface and the bottom surface of the rubber heat insulation strip, thereby driving the rubber heat insulation strip to move, and the stable transmission of the rubber heat insulation strip is realized.

[0061] Further improvement is that the cooling device further comprises a heat exchange tank 7, the cooling tank 1 is arranged in the heat exchange tank 7, the upper portion of the side wall of the heat exchange tank 7 is provided with an overflow port 11, the bottom of the heat exchange tank 7 is connected with a liquid discharge pipe 12, and the liquid discharge pipe 12 is connected with a liquid discharge valve 13.

[0062] Specifically, the bottom of the cooling tank 1 is fixed above the bottom of the heat exchange tank 7 through the supporting leg 17, the circumferential side wall of the cooling tank 1 is provided with the overflow port 11, the liquid discharge pipe 12 is fixedly and sealingly penetrated through the side wall of the heat exchange tank 7, and the liquid discharge valve 13 is located outside the heat exchange tank 7; the flange 15 is provided with the liquid inlet 16, the liquid inlet 16 is located directly above the heat exchange tank 7, the flange 15 is fixed with the liquid conveying pump 8 directly above, the input end of the liquid conveying pump 8 is used for connecting a water source of the cooling liquid, and the output end is in communication with the liquid inlet 16.

[0063] With the above structure, the cooling liquid is also filled in the heat exchange tank 7, the liquid level of the cooling liquid in the heat exchange tank 7 reaches the height position of the overflow port 11, and the liquid level of the cooling liquid in the cooling tank 1 is lower than the overflow port 11; when the rubber heat insulation strip is cooled, the cooling liquid in the heat exchange tank 7 absorbs the heat of the cooling liquid in the cooling tank 1 through the tank wall of the cooling tank 1, thereby delaying the temperature rising speed of the cooling liquid in the cooling tank 1, so as to ensure that there is enough temperature difference between the cooling liquid in the cooling tank 1 and the rubber heat insulation strip, thereby ensuring the cooling effect.

[0064] After being used for a period of time, the cooling liquid in the cooling tank 1 absorbs the heat of the rubber heat insulation strip and part of impurities, and the cooling effect becomes poor, at this time, the liquid discharge valve 13 is opened, so that the cooling liquid in the cooling tank 1 is discharged through the liquid discharge valve 13; then, the liquid discharge valve 13 is closed, the liquid conveying pump 8 conveys the cooling liquid into the heat exchange tank 7, and when the liquid level of the cooling liquid rises, the cooling liquid flows into the cooling tank 1 from the overflow port 11, until the liquid level of the cooling liquid in the cooling tank 1 reaches a certain height, the liquid conveying pump 8 stops conveying the cooling liquid, and the device can continue to cool the rubber heat insulation strip.

[0065] Second embodiment

[0066] As shown in Figure 11 the second embodiment of the rubber heat insulation strip cooling device of the utility model, based on the first embodiment, the difference lies in that the cooling tank 1 is provided with an ultrasonic transducer 14.

[0067] Specifically, the ultrasonic transducer 14 is fixed to the bottom of the cooling pool 1, and when the rubber heat insulation strip passes through the transmission gap, the ultrasonic transducer 14 is started to generate high-frequency vibration in the cooling liquid to form tiny bubbles. These bubbles undergo the processes of formation, growth and violent collapse under the action of ultrasonic waves, and when collapsing, long high-pressure, shock waves and micro-jet streams and other phenomena can form strong micro-flow effects in the cooling liquid. The micro-flow effect helps to break the static stratification of the cooling liquid in the cooling pool 1, so that the cooling liquid can flow more uniformly and contact each surface of the rubber heat insulation strip, promoting the rubber heat insulation strip to be uniformly cooled in the cooling pool 1 and improving the cooling effect. Moreover, the tiny bubbles generated by the ultrasonic transducer 14 can produce a huge instantaneous pressure when collapsing, which can destroy and peel off the particulate impurities on the surface of the rubber heat insulation strip, and further remove the stubborn stains and impurities formed on the surface of the rubber heat insulation strip during the production process, thereby achieving cleaning while cooling the rubber heat insulation strip.

[0068] Obviously, the above embodiments are only examples for clearly illustrating the present application, and are not intended to limit the embodiments. Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or modifications derived therefrom are still within the protection scope of the present application.
