Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a cooling device for asphalt roll extrusion. Background Technology

[0002] In the production process of asphalt rolls, the surface temperature of the asphalt rolls is usually high after extrusion molding. If effective cooling treatment is not carried out in time, it will not only affect subsequent processing steps, such as cutting and winding, but may also cause unstable performance of the rolls due to excessive temperature, or even deformation and damage. Therefore, cooling the extruded asphalt rolls is one of the most important steps in the production process.

[0003] CN220808460U discloses a cooling device for extruded waterproof asphalt rolls. The extruded asphalt rolls are fed into a cooling box, and after cooling, they enter a cleaning box. A servo motor drives two bevel gears on a rotating rod to rotate, two extrusion rollers clean the residual moisture on the surface, and two water-absorbing rollers perform a secondary cleaning. However, in actual production applications, this method of relying on water-absorbing rollers to remove residual moisture from the roll surface has significant drawbacks. As production continues, the water-absorbing rollers continuously absorb moisture from the roll surface. When the absorbed moisture reaches a certain amount, their absorption capacity significantly decreases or even disappears completely. At this point, not only can they no longer effectively remove residual moisture from the asphalt roll surface, but because the water-absorbing rollers themselves carry a large amount of moisture, they will re-adhere moisture to the roll surface during contact. Therefore, this utility model proposes an extruded asphalt roll cooling device. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that the water absorption capacity of the existing asphalt roll extrusion cooling device decreases or is even lost after the water absorption roller absorbs a certain amount of water, and the water will re-adhere to the surface of the roll. The invention proposes an asphalt roll extrusion cooling device.

[0005] The technical solution of this utility model is as follows: an asphalt roll extrusion cooling device, comprising a cooling box containing cold water; multiple sets of guide rollers rotatably connected to the cooling box, with the roll body wound on the guide rollers; a support frame disposed on one side of the cooling box, with two sets of mounting boxes disposed above the support frame, the two sets of mounting boxes being symmetrically disposed on both sides of the roll body, multiple sets of connecting plates fixedly connected between the two sets of mounting boxes, and the lower set of mounting boxes being fixedly connected to the support frame; a wiping mechanism installed in the mounting box, the wiping mechanism comprising two sets of sleeves, with a wiping cloth layer disposed on the outer ring of the sleeves, the wiping cloth layer contacting the surface of the roll body; and two sets of heating modules disposed in the mounting box, the heating modules being used to dry the wiping cloth layer.

[0006] Optionally, the wiping mechanism includes two sets of mounting plates disposed in the mounting box, two sets of rotating rods rotatably connected between the two sets of mounting plates, and two sets of sleeves respectively fixedly sleeved on the outer rings of the two sets of rotating rods, with the sleeves located between the two sets of mounting plates.

[0007] Optionally, the wiping mechanism further includes a servo motor mounted on the side of the mounting box. The output end of the servo motor passes through one side of the mounting plate and is fixedly connected to a first gear. A second gear is provided on both sides of the first gear to mesh with it. The ends of the two sets of rotating rods near the servo motor are fixedly connected to the two sets of second gears.

[0008] Optionally, a positioning rod is fixedly connected between the two sets of mounting plates. The positioning rod is coaxially arranged with the output end of the servo motor. The end of the positioning rod away from the servo motor passes through the mounting box and is fixedly connected to a third gear. A rack that meshes with the third gear is provided on one side.

[0009] Optionally, a fixing block is installed on the side of the mounting box away from the servo motor, and a limit groove is formed on the fixing block, and the rack is slidably connected in the limit groove.

[0010] Optionally, a sliding groove is provided on the side of the limiting groove near the mounting box, and a slider is slidably connected in the sliding groove. The slider has a T-shaped structure and is fixedly connected to the rack.

[0011] Optionally, cold water circulates in the cooling box.

[0012] Optionally, the two sets of heating modules are symmetrically arranged on both sides of the sleeve, and a temperature sensor for monitoring the ambient temperature is installed in the mounting box.

[0013] Optionally, a control module is also included, wherein the servo motor, heating module, and temperature sensor are all electrically connected to the control module.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention utilizes two sets of switchable wiping cloth layers in the wiping mechanism, along with the linkage of servo motors, first gears, second gears, third gears, and racks, to precisely switch the positions of the two sets of wiping cloth layers before one set of wiping cloth layers reaches saturation with moisture on the surface of the roll material. Simultaneously, the wiping cloth layer switched to the drying position can be quickly dried by the heating module inside the mounting box, ensuring that the wiping cloth layer always maintains good water absorption capacity. This completely solves the problem of traditional water absorption rollers failing due to moisture accumulation and re-adhering moisture to the surface of the roll material, ensuring the smooth progress of subsequent processing of the roll material and improving product quality stability.

[0016] Furthermore, the guide rollers ensure that the roll body moves smoothly in the cooling box, the chute and T-shaped slider work together to ensure that the rack moves smoothly, and the connecting plate fixes the positions of the two sets of mounting boxes. The stable cooperation of multiple sets of components makes the overall equipment highly reliable, reduces the number of downtime maintenance caused by component failure, and reduces the operation and maintenance costs in the production process.

[0017] In summary, this invention achieves continuous and efficient removal of moisture from the surface of roll materials through two sets of switchable and dryable wiping cloth layers, ensuring smooth subsequent processing and improving product quality stability. Attached Figure Description

[0032] Example

[0033] like Figure 1 and Figure 2 As shown, the present invention proposes an asphalt roll extrusion cooling device, which includes a cooling box 1 containing cold water. The cold water in the cooling box 1 is circulated by a water pump to prevent the roll temperature from heating the cold water in the cooling box 1, which would lead to a poor cooling effect of the roll in the future.

[0034] Furthermore, the aforementioned cooling device includes multiple sets of guide rollers 2 rotatably connected to the cooling box 1, with a roll body 3 wound around the multiple sets of guide rollers 2. The movement of the roll body 3 is achieved by existing traction equipment, which is prior art and will not be described in detail here.

[0035] Furthermore, the aforementioned cooling device also includes a support frame 4 located on one side of the cooling box 1. Two sets of mounting boxes 5 are located above the support frame 4. The two sets of mounting boxes 5 are symmetrically arranged on both sides of the roll body 3. Multiple sets of connecting plates 6 are fixedly connected between the two sets of mounting boxes 5. The lower set of mounting boxes 5 is fixedly connected to the support frame 4. The positions of the support frame 4, mounting boxes 5, and connecting plates 6 are fixed.

[0036] For details, please refer to Figures 2 to 5The aforementioned cooling device includes a wiping mechanism 7 installed in the mounting box 5. The wiping mechanism 7 includes two sets of sleeves 73, with a wiping cloth layer 74 disposed on the outer ring of each sleeve 73. The wiping cloth layer 74 contacts the surface of the roll material body 3, and absorbs moisture from its surface after contact. The wiping mechanism 7 includes two sets of mounting plates 71 disposed in the mounting box 5, with two sets of rotating rods 72 rotatably connected between the two sets of mounting plates 71. The two sets of sleeves 73 are respectively fixedly sleeved on the outer ring of the two sets of rotating rods 72, and the sleeves 73 are located between the two sets of mounting plates 71. The wiping mechanism 7 also includes a servo motor 75 mounted on the side of the mounting box 5. The output end of the servo motor 75 passes through one side of the mounting plate 71 and is fixedly connected to a first gear 76. Second gears 77 mesh with the first gear 76 on both sides. Two sets of rotating rods 72 are fixedly connected to the two sets of second gears 77 at their ends near the servo motor 75. After the servo motor 75 starts, it drives the two sets of second gears 77 to rotate via the first gear 76, thereby causing the two sets of rotating rods 72 to rotate synchronously. A positioning rod 78 is fixedly connected between the two sets of mounting plates 71. The positioning rod 78 is coaxially arranged with the output end of the servo motor 75. The end of the positioning rod 78 away from the servo motor 75 passes through the mounting box 5 and is fixedly connected to a third gear 79. The positioning rod 78 allows the two sets of mounting plates 71 to rotate around it. After the servo motor 75 starts, due to the friction between the first gear 76 and the second gears 77, the mounting plate 71 can rotate before the first gear 76 drives the second gears 77 to rotate, thereby causing the positioning rod 78 to rotate synchronously. A rack 710 meshes with the third gear 79 on one side, and the rack 710 rotates synchronously with the third gear 79. A fixing block 711 is installed on the side of the mounting box 5 away from the servo motor 75. A limiting groove 712 is formed on the fixing block 711, and the rack 710 is slidably connected in the limiting groove 712. The limiting groove 712 limits the movement distance of the rack 710, thereby limiting the third gear 79 to rotate only 180°. Thus, after one end of the rack 710 contacts the limiting groove 712, the third gear 79 cannot rotate out, and only then does the first gear 76 drive the second gear 77 to rotate. By controlling the rotation direction of the servo motor 75, the positions of the two sets of wiping cloth layers 74 are switched. At the same time, after the position is switched, the two sets of wiping cloth layers 74 begin to rotate, so that one set of wiping cloth layers 74 can absorb moisture from the surface of the roll body 3, while drying the other set of wiping cloth layers 74. The limiting groove 712 has a sliding groove 713 on the side near the mounting box 5. A slider 714 is slidably connected in the sliding groove 713. The slider 714 has a T-shaped structure and is fixedly connected to the rack 710. The sliding groove 713 and the slider 714 make the movement of the rack 710 smooth.

[0037] Furthermore, the aforementioned cooling device includes two sets of heating modules 8 disposed in the mounting box 5. The heating modules 8 are used to dry the wiping cloth layer 74. The two sets of heating modules 8 are symmetrically disposed on both sides of the sleeve 73. The mounting box 5 is equipped with a temperature sensor to monitor the ambient temperature and prevent the drying temperature from being too high.

[0038] Finally, the cooling device also includes a control module. The servo motor 75, the heating module 8, and the temperature sensor are all electrically connected to the control module and are controlled in a comprehensive manner through the control module.

[0039] In this embodiment, during the cooling stage, the cooling box 1 contains cold water for cooling, and the cold water is circulated by a water pump. This effectively prevents the high temperature of the roll body 3 from heating the cold water in the cooling box 1, thus preventing a decrease in the cooling effect of the roll body 3. Under the traction of the existing traction equipment, the roll body 3 moves along multiple sets of guide rollers 2 that are rotatably connected inside the cooling box 1, making full contact with the cold water in the cooling box 1 during the movement, thereby achieving rapid cooling.

[0040] When the servo motor 75 starts, the first gear 76, which is fixedly connected to the mounting plate 71 through the output end of the servo motor 75, starts to drive the second gear 77 to rotate. The rotating rod 72, which is fixedly connected to the second gear 77, rotates synchronously, thereby driving the wiping cloth layer 74 to rotate and absorb the moisture on the surface of the roll body 3.

[0041] The servo motor 75 on the side of the mounting box 5 is periodically controlled by the control module to rotate in opposite directions. The output end of the servo motor 75 passes through the mounting plate 71 and is fixedly connected to the first gear 76. Due to the friction between the first gear 76 and the second gears 77 meshing on both sides, before driving the second gears 77 to rotate, it will first drive the two sets of mounting plates 71 to rotate around the positioning rod 78. When the mounting plate 71 rotates, it drives the positioning rod 78 to rotate synchronously, which in turn causes the third gear 79 to rotate. The rack 710 meshing with the third gear 79 slides in the limiting groove 712 of the fixed block 711. When one end of the rack 710 contacts the inner wall of the limiting groove 712, the third gear 79 can no longer rotate. At the same time, the position switching of the two sets of wiping cloth layers 74 is completed. The wiping cloth layer 74 switched to the drying position is dried by the heating modules 8 symmetrically arranged on both sides of the sleeve 73 inside the mounting box 5. The temperature sensor installed inside the mounting box 5 monitors the ambient temperature in real time and transmits the data to the control module. The control module adjusts the working state of the heating module 8 according to the temperature data to prevent the drying temperature from being too high and damaging the wiping cloth layer 74.

[0042] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
