Description

Technical Field

[0001] The utility model relates to the technical field of asphalt anti-rutting agent production, in particular to a high-efficiency water-cooled drawing asphalt anti-rutting agent forming device. Background Art

[0002] Asphalt pavements can experience significant permanent deformation and rutting under high temperatures and sustained heavy loads. This damage not only affects the pavement's smoothness and driving safety, but also its performance and service life. To prevent and control rutting and extend the pavement's service life, adding anti-rutting agents to the asphalt mixture is an effective measure. These agents typically appear as black granules. During production, they are often drawn through an extruder, water-cooled, and then peeled into granular form.

[0003] According to the published patent CN208452265U, the cooling water tank of the clip chain extruder includes a water tank body, a roller located at the bottom right side of the water tank body, and a lead-out roller located at the upper left side of the water tank body. The plastic clip chain extruded by the extrusion die of the clip chain extruder is wound around the roller and then led out by the lead-out roller. The characteristic is that the roller is connected to a lifting rocker arm, and the lifting rocker arm is set to swing up and down. After the lifting rocker arm swings upward, the roller can be lifted above the water surface. The utility model can make the threading operation of the plastic clip chain easier when entering the cooling water tank for cooling, avoiding getting the sleeves wet. At the same time, the size of the cooling water tank can be designed to be smaller. When the cooling water tank is small, it can still well ensure that the plastic clip chain has enough time to cool. During use, the traditional extruder cooling water tank is often used to extrude the material in strips by the extruder, pass it through the inside of the cooling water tank, and then cool and shape the material in combination with the cooling water inside the cooling water tank. However, due to the temperature of the processing site environment and the use time of the cooling water inside the cooling water tank, the temperature of the cooling water inside the cooling water tank itself will change and affect the cooling effect, thereby making it easy for the contact time between the strip anti-rutting agent passing through the cooling water tank and the cooling water to be insufficient, thereby reducing the cooling effect of the cooling water on it, affecting the cooling and shaping quality of the anti-rutting agent. For this reason, it is necessary to design a new technical solution to provide a solution. Utility Model Content

[0024] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0025] Example 1: High-efficiency water-cooled drawing asphalt anti-rutting agent forming device, see Figures 1 to 3 , a gear box 11 is fixedly installed on the top surface of the control machine 1, a heating conveying pipe 12 is installed on the top surface of the gear box, and a feed pipe 13 is fixedly connected to the top of the heating conveying pipe 12, and an extrusion pipe 14 is fixedly installed on the side of the gear box 11, and hollow frames 2 are vertically fixedly installed on both end surfaces of the inner side of the box body 16, and the number of hollow frames 2 is four groups, and a bidirectional screw rod 21 is vertically rotatably installed on the inside of each hollow frame 2 through a bearing, and a transmission sleeve 22 is movably sleeved on the outer end surfaces of each bidirectional screw rod 21 through a thread, and the sides of each two groups of transmission sleeves 22 are respectively fixed with a first connecting block 23 and a second connecting block 24, and the second connecting block 24 is located below the first connecting block 23, and a lifting plate 25 is fixedly installed on the outer surface of each of the first connecting block 23 and the second connecting block 24, and the lifting plate 25 slides and fits the outer side of the hollow frame 2, A connecting frame 26 is fixedly installed between the sides of each two groups of the lifting plates 25, and an I-shaped rod 29 is rotatably installed inside each of the connecting frames 26 through a bearing. A rotating roller 27 is fixedly sleeved on the middle end surface of each I-shaped rod 29. By arranging two groups of rotating rollers 27 at the diagonal position outside the hollow frame 2, and combining the rotation transmission action of the transmission sleeve 22 by the bidirectional screw 21, when the temperature of the cooling water inside the box 16 is too high, the distance between the two groups of rotating rollers 27 is increased, so that the strip anti-rutting agent passing through the interior can extend the movement and cooling distance of the strip anti-rutting agent inside the box 16 under the guiding and limiting action of the rotating roller 27, thereby increasing the contact time between the anti-rutting agent and the cooling water inside the box 16, thereby improving the cooling quality of the anti-rutting agent, and avoiding the increase in the cooling water temperature affecting the cooling and shaping quality of the anti-rutting agent.

[0026] For details, see Figures 1 to 3 The side of the extrusion tube 14 is fixedly connected to an extrusion tube head 15, the bottom of the side of the control machine 1 is fixedly connected to the outside of the box 16, and the extrusion tube head 15 is located above the box 16. By placing the extrusion tube head 15 above the box 16, the strip anti-rutting agent removed from the extrusion tube head 15 can directly fall into the inside of the box 16 for cooling treatment.

[0027] For further information, see Figures 1 to 3A servo motor 28 is fixedly installed on the top surface of each hollow frame 2, and the bottom of the servo motor 28 drive shaft is fixedly connected to the top surface of the bidirectional screw 21 through a coupling. A temperature sensor 3 is fixedly embedded in the middle end of the inner bottom of the box body 16, and a controller 31 is fixedly installed on the outer bottom surface of the box body 16. Through the mutual cooperation of the temperature sensor 3 and the controller 31, the operation automation of the overall cooling adjustment mechanism can be improved to avoid affecting the cooling and shaping quality of the anti-rutting agent due to untimely adjustment.

[0028] It is worth noting that, see Figures 1 to 3 The signal output end of the temperature sensor 3 is electrically connected to the signal input end of the controller 31, and the signal output end of the controller 31 is electrically connected to the signal input end of the servo motor 28. Through the electrical connection between the various components, the rationality of the control transmission of the entire device can be guaranteed.

[0029] It is worth noting that see Figures 1 to 3 A limiting groove 4 is provided at both ends of the side of each hollow frame 2, and the first connecting block 23 and the second connecting block 24 are slidably inserted into the limiting groove 4. Through the guiding and limiting action of the limiting groove 4 on the first connecting block 23 and the second connecting block 24, when the bidirectional screw rod 21 rotates, the transmission sleeve 22 sleeved on its surface will not rotate axially, thereby ensuring the rationality of the transmission adjustment of the entire device.

[0030] It is worth mentioning that see Figures 1 to 3 The outer surface of each rotating drum 27 is fixedly sleeved with a limiting sleeve 5, and the number of the limiting sleeves 5 is several groups. The setting of the limiting sleeves 5 ensures that the strip anti-rutting agent placed on the surface of the rotating drum 27 is limited to avoid arbitrary shaking under the buoyancy of the cooling water and entanglement with each other, affecting the shaping quality.

[0031] During operation, the materials required for the production of the anti-rutting agent are transported to the inside of the heating conveying pipe 12 through the feed pipe 13 and heated. The materials are then mixed by the spiral extrusion of the extrusion pipe 14. The mixed anti-rutting agent materials are then extruded into strips by the extrusion pipe head 15 and transported to the inside of the box 16. The operator then pulls one end of the extruded strip anti-rutting agent to pass between the rotating roller 27 and the connecting frame 26. After placing a single strip anti-rutting agent between the outer sides of the limiting sleeve 5, the controller 31 and the temperature sensor 3 are started. When the temperature sensor 3 detects the internal temperature of the box 16, if the internal temperature of the box 16 is too high, the temperature information is transmitted to the controller 31. The converter inside the controller 31 converts the signal and compares it with the set temperature threshold for judgment. , start the servo motor 28, make it run and drive the bidirectional screw rod 21 to rotate synchronously inside the hollow frame 2, and under the guiding and limiting action of the limit groove 4 on the first connecting block 23 and the second connecting block 24, the transmission sleeve 22 sleeved on both sides of the bidirectional screw rod 21 can be synchronously moved vertically relative to each other, and then, under the transmission connection action of the first connecting block 23 and the second connecting block 24, a corresponding driving force can be provided to the two groups of lifting plates 25 and the rotating roller 27, so that the two groups of corresponding rotating rollers 27 can move vertically relative to each other and increase the distance between them, and then during the vertical movement of the rotating roller 27, the strip anti-rutting agent supported on its surface can be guided to move, so that the strip anti-rutting agent increases its contact area and contact time with the cooling water inside the box body 16, thereby ensuring the cooling and shaping quality of the strip anti-rutting agent.
