Description

Technical Field

[0001] This utility model relates to the field of forming roller technology, specifically to a forming roller for asphalt waterproof membrane. Background Technology

[0002] Asphalt waterproof membrane is a type of waterproof membrane made by impregnating a base material with asphalt and then sprinkling powdered or sheet-like separating material on the surface. In the production process of asphalt waterproof membrane, the forming roller is a key component, mainly used to extrude and shape the membrane to ensure that the membrane meets the specified requirements for thickness, width and surface flatness.

[0003] In existing technologies, two circular forming rollers are typically used, with a gap between them. The asphalt waterproof membrane raw material is extruded and formed in the gap. The forming rollers are usually equipped with electric heating rods, and some are also equipped with a metal heat-conducting layer and a temperature controller to precisely control the temperature of the forming rollers and ensure the forming effect of the asphalt waterproof membrane. The production process is roughly as follows: the mixed asphalt waterproof membrane raw material is conveyed to the gap between the two forming rollers. As the forming rollers rotate, the raw material is extruded and filled into the mold or the set shape, initially forming a waterproof membrane with a certain thickness and shape. For example, in the self-adhesive rubber asphalt waterproof membrane non-woven forming equipment, the forming rollers are driven by an electric motor to rotate, so that the rubber asphalt material is precisely formed under the action of the forming rollers. However, after the raw material is formed, asphalt residue and impurities will be adsorbed on the two forming rollers. Usually, the forming rollers are cleaned manually using special cleaning agents and tools (such as brushes) periodically. However, manual cleaning inevitably has cleaning dead corners and is inconvenient to operate. Utility Model Content

[0004] This utility model proposes a forming roller for asphalt waterproof membrane, which solves the problem that manual cleaning in the prior art inevitably has blind spots and is inconvenient to operate.

[0005] The technical solution of this utility model is as follows: A forming roller for asphalt waterproof membrane is applied to a workbench. A first forming roller is rotatably embedded in the workbench, and a mounting frame is fixedly connected to the workbench. A second forming roller is rotatably arranged inside the mounting frame. Both the first and second forming rollers are rotated by a drive mechanism. The system also includes a moving frame, a cleaning mechanism, and a collection frame. The moving frame is movably arranged inside the mounting frame via the moving mechanism. The cleaning mechanism is rotatably arranged inside the moving frame via a rotating component and is used to cooperate with the drive mechanism to scrape off the residue on the surface of the second forming roller and perform cleaning. The collection frame is fixedly connected to the bottom end of the moving frame and is used to collect the residue scraped off the forming roller.

[0006] Preferably, the moving mechanism includes a connecting plate, a limiting plate, and an electric cylinder. The mounting frame has a moving groove, the connecting plate slides in conjunction with the inner wall of the moving groove, one end of the connecting plate is fixedly connected to one end of the moving frame, both ends of the connecting plate are provided with the limiting plate, the mounting frame has a limiting groove that cooperates with the limiting plate, the electric cylinder is mounted on the mounting frame, and the output end of the electric cylinder is fixedly connected to the other end of the connecting plate.

[0007] Furthermore, the cleaning mechanism includes a cleaning roller, a scraper, a brush, and a quick-release mechanism. The cleaning roller is rotatably mounted on the movable frame, the scraper is detachably mounted on the cleaning roller, and the brush is detachably mounted on the cleaning roller. Both the scraper and the brush are detachably connected to the cleaning roller via quick-release mechanisms.

[0008] Furthermore, the quick-release component includes a fixing plate, an insert plate, and a bolt. One end of the fixing plate is fixedly connected to the cleaning roller. A slot is provided on the fixing plate. One end of both the scraper and the brush is fixedly connected to the insert plate. The other end of the insert plate slides against the inner wall of the slot. Both the fixing plate and the insert plate are threadedly engaged with the bolt.

[0009] As a further embodiment of this application, the rotating assembly includes a rotating shaft and a drive motor. The rotating shaft is rotatably disposed within the movable frame. The cleaning roller is fitted onto the rotating shaft and is coaxially and fixedly connected to the rotating shaft. The drive motor is mounted on the movable frame, and the output end of the drive motor is coaxially and fixedly connected to one end of the rotating shaft.

[0010] As a further improvement in this application, the mounting bracket is provided with a slot that matches the movement trajectory of the drive motor.

[0011] The beneficial effects of this utility model are as follows:

[0012] In this invention, through the cooperation of a moving frame, a moving mechanism, a cleaning mechanism, a collection frame, and a driving mechanism, the electric cylinder is activated to drive one end of the scraper and the collection frame to abut against the second forming roller. Then, the driving mechanism drives the second forming roller and the first forming roller to rotate. The edge of the scraper makes slight contact with the roller surface to scrape off the semi-solid asphalt or debris adhering to the surface and collect it in the collection frame. Then, the driving motor is activated to drive the cleaning roller to rotate 180 degrees and then keep it stable. In this way, the positions of the brush and the scraper are switched, and the residual small impurities after the scraper cleaning are cleaned a second time. This can clean the surface of the second forming roller and prevent residue from adhering to the second forming roller, which would affect subsequent use.

[0013] In this invention, the brush, scraper, and quick-release parts work together. By inserting the insert plate into the slot and then using bolts to fix the insert plate and the fixing plate, the brush and scraper can be fixed on the cleaning roller, making it easy to disassemble, clean, and replace.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-6As shown, this embodiment proposes a forming roller for asphalt waterproof membrane, which is applied to a workbench 1. A first forming roller 2 is rotatably embedded in the workbench 1, and a mounting frame 3 is fixedly connected to the workbench 1. A second forming roller 4 is rotatably arranged inside the mounting frame 3. Both the first forming roller 2 and the second forming roller 4 are rotated by a drive mechanism 5. The system also includes a moving frame 6, a cleaning mechanism, and a collection frame 7.

[0024] It should be added that the workbench 1 has a groove that mates with the first forming roller 2. The outer wall of the first forming roller 2 abuts against and slides against the inner wall of the groove. The first forming roller 2 and the second forming roller 4 are both coaxially fixedly connected to a connecting shaft. The drive mechanism 5 includes a first motor and a gear. The first motor is coaxially fixedly connected to one end of a connecting shaft. Gears are fitted on both connecting shafts and are coaxially fixedly connected to the gears. By starting the first motor, the output end of the first motor rotates, driving one connecting shaft to rotate. This connecting shaft drives the gear connected to it to rotate. This gear drives the other gear and the connecting shaft to rotate. The rotation of the two connecting shafts respectively drives the first forming roller 2 and the second forming roller 4 to rotate to perform the forming work of the asphalt waterproof membrane.

[0025] However, when the first forming roller 2 rotates under the drive of the drive mechanism 5, the inner wall of the groove will scrape off the residue on the surface of the first forming roller 2, while the residue will adhere to the second forming roller 4.

[0026] like Figure 2 As shown, the movable frame 6 is movably mounted in the mounting frame 3 via a moving mechanism. The movable frame 6 is U-shaped. The moving mechanism includes a connecting plate 8, a limiting plate 9, and an electric cylinder 10. The mounting frame 3 has a moving groove 11. The connecting plate 8 slides in cooperation with the inner wall of the moving groove 11. One end of the connecting plate 8 is fixedly connected to one end of the movable frame 6. Both ends of the connecting plate 8 are provided with limiting plates 9. The mounting frame 3 has a limiting groove 12 that cooperates with the limiting plates 9. The limiting plates 9 slide in the limiting groove 12 and can support the movable frame 6 and keep the movable frame 6 horizontal. The electric cylinder 10 is mounted on the mounting frame 3. The output end of the electric cylinder 10 is fixedly connected to the other end of the connecting plate 8. By starting the electric cylinder 10, the output end of the electric cylinder 10 drives the connecting plate 8 to move horizontally. The connecting plate 8 drives the two limiting plates 9 to move along the inner wall of the limiting groove 12. The connecting plate 8 drives the movable frame 6 to move horizontally within the mounting frame 3.

[0027] like Figure 3 and Figure 4As shown, the cleaning mechanism is rotatably mounted within the movable frame 6 via a rotating assembly. It works in conjunction with the drive mechanism 5 to scrape away residue from the surface of the second forming roller 4 and perform cleaning. The cleaning mechanism includes a cleaning roller 13, a scraper 14, a brush 15, and quick-release components. The cleaning roller 13 is rotatably mounted on the movable frame 6. The scraper 14 is detachably mounted on the cleaning roller 13, and the brush 15 is detachably mounted on the cleaning roller 13. The brush 15 is made of nylon with moderate hardness. Both the scraper 14 and the brush 15 are detachably connected to the cleaning roller 13 via quick-release components. The scraper 14 and the brush 15 are symmetrically arranged along the axis of the cleaning roller 13. The quick-release components include a fixing plate 1. 6. Insert plate 17 and bolt 18: One end of the fixing plate 16 is fixedly connected to the cleaning roller 13. The fixing plate 16 has a slot 19. One end of the scraper 14 and the brush 15 are fixedly connected to the insert plate 17. The other end of the insert plate 17 slides with the inner wall of the slot 19. The fixing plate 16 and the insert plate 17 are threaded with the bolt 18. Taking the scraper 14 as an example, by inserting the insert plate 17 into the slot 19, and then using the bolt 18 to fix the insert plate 17 and the fixing plate 16, the scraper 14 can be fixed on the cleaning roller 13. The same applies to the brush 15. This facilitates the subsequent cleaning and replacement of the scraper 14 and the brush 15.

[0028] like Figure 5 As shown, the rotating assembly includes a rotating shaft 20 and a drive motor 21. The rotating shaft 20 is rotatably mounted inside the movable frame 6. The cleaning roller 13 is mounted on the rotating shaft 20 and is coaxially fixedly connected to the rotating shaft 20. The drive motor 21 is mounted on the movable frame 6. The output end of the drive motor 21 is coaxially fixedly connected to one end of the rotating shaft 20. The drive motor 21 is a power-off braking motor, which can keep the rotating shaft 20 stable when the power is off. The mounting frame 3 has a slot 22 that matches the movement trajectory of the drive motor 21. By starting the drive motor 21, the output end of the drive motor 21 rotates 180 degrees and then remains stable, thus swapping the positions of the brush 15 and the scraper 14.

[0029] The collection frame 7 is fixedly connected to the bottom of the movable frame 6 and is used to collect the residue scraped off the forming roller. One end of the collection frame 7 is arc-shaped and matches the outer side wall of the second forming roller 4. After the production of the asphalt waterproof membrane is completed, the movable frame 6 drives the scraper 14 to abut against the second forming roller 4 under the drive of the moving mechanism. The second forming roller 4 is rotated by the drive mechanism 5, so that the residue on the second forming roller 4 is scraped off and falls into the collection frame 7.

[0030] Working principle: After the production of the asphalt waterproof membrane is completed, the forming roller of this asphalt waterproof membrane pre-inserts the insert plate 17 into the slot 19, and then uses bolts 18 to fix the insert plate 17 and the fixing plate 16. This fixes the brush 15 and scraper 14 onto the cleaning roller 13. By activating the electric cylinder 10, the output end of the electric cylinder 10 drives the connecting plate 8 to move horizontally. The connecting plate 8 drives the two limit plates 9 to move along the inner wall of the limit groove 12. The connecting plate 8 drives the moving frame 6 to move horizontally towards the second forming roller 4 within the mounting frame 3. When one end of the scraper 14 and the collection frame 7 both abut against the second forming roller 4, the electric cylinder 10 stops working and drives the second forming roller 4 and the first forming roller 2 to rotate through the drive mechanism 5. The edge of the scraper makes slight contact with the roller surface and scrapes off the semi-solid asphalt or debris adhering to the surface as the second forming roller 4 rotates, and collects it in the collection frame 7. Then, by starting the drive motor 21, the output end of the drive motor 21 rotates 180 degrees and then remains stable, thus exchanging the positions of the brush 15 and the scraper 14 to perform a secondary cleaning of the residual small impurities after the scraper cleaning.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
