Description

Technical Field

[0001] This invention relates to the field of steel-edged rubber waterstop technology, specifically to an extrusion device for steel-edged rubber waterstops. Background Technology

[0002] Steel-edged rubber waterstops are materials used for watertight treatment of buildings, effectively preventing leaks and seepage. They are mainly composed of rubber and steel sheets, offering flexibility and good waterproofing. The steel edges ensure the integrity of the rubber during installation. The production of steel-edged rubber waterstops requires extrusion equipment, but existing extrusion equipment has some shortcomings.

[0003] For example, CN115122546A discloses an extrusion device for steel-edged rubber waterstops. When producing waterstops, the operator pulls the rubber and steel strips from the rubber conveyor rollers and steel conveyor rollers through the feed trough on the clamp. Simultaneously, activating the hydraulic telescopic rod moves the moving heating plate downwards, utilizing the combined heating effect of the moving and fixed heating plates to heat and bond the steel strip and rubber strip. The produced waterstop is then wound onto the waterstop take-up roller. Starting the motor rotates the take-up roller, achieving simultaneous production and winding of the waterstop. This device boasts a high degree of automation and reduces the workload of the operators. However, while the above device can achieve automatic winding, in actual use, it cannot automatically perform heat fusion bonding of the rubber and steel sheets and rapidly cool the bonding area. Existing extrusion equipment cannot automatically drill holes in the surface of the steel sheet using the conveying structure before hot-melt bonding to ensure a secure connection. Furthermore, it cannot guide the steel sheet during production, impacting processing efficiency. When conveying rubber waterstops, existing extrusion equipment cannot adaptively adjust the position of the conveyor rollers according to the undulating and smooth areas of the rubber waterstop surface. Summary of the Invention

[0007] As a preferred embodiment of the present invention, the support base, the outer shell, the connecting shell, and the guide plate are integral, and the outer shell, the connecting shell, and the guide plate are interconnected.

[0008] As a preferred embodiment of the present invention, there is a gap between two adjacent filler plates, and the height of the gap between two adjacent filler plates is equal to the thickness of the steel sheet.

[0009] As a preferred embodiment of the present invention, the guide assembly includes side plates fixedly installed on the left and right sides of the support base, and fixed plates are fixedly connected to the front and rear sides of the side plates. A first rotating rod is installed above the fixed plate, and a second rotating rod is provided below the first rotating rod. The first rotating rod and the second rotating rod are rotatably connected to the fixed plate, and the first rotating rod and the second rotating rod are symmetrically distributed on the upper and lower sides of the steel sheet.

[0010] As a preferred embodiment of the present invention, the conveying assembly includes a first fixed plate fixedly installed on the left side of the connecting shaft, a second fixed plate fixedly connected to the left side of the first fixed plate, threaded holes being provided around the perimeter of both the first and second fixed plates, and a punching cutter head being installed in the internal threads of the threaded holes, a first connecting rod fixedly connected to the left side of the second fixed plate, a first conveying wheel fixedly connected to the left side of the first connecting rod, a second conveying wheel being disposed below the first conveying wheel, a second connecting rod fixedly installed in the middle of the second conveying wheel, and the second connecting rod being rotatably connected to both the first and second fixed frames.

[0011] As a preferred embodiment of the present invention, the diameter of the second fixing plate is smaller than the diameter of the first fixing plate, and the diameter difference between the first fixing plate and the second fixing plate is equal to the height difference between the rubber waterstop body and the upper surface of the steel sheet.

[0012] As a preferred embodiment of the present invention, a keyway is provided inside the first conveying wheel, a key block is fixedly connected to the surface of the first connecting rod, and a damping block is fixedly connected to the surface of the key block.

[0013] As a preferred embodiment of the present invention, the connection method between the second conveying wheel and the second connecting rod is the same as the connection method between the first conveying wheel and the first connecting rod, and the position of the first conveying wheel corresponds to the position of the first connecting rod.

[0014] As a preferred embodiment of the present invention, the cooling assembly includes a connecting rod fixedly installed between the first fixing frame and the second fixing frame. A fixing tube is fixedly connected to the outer side of both ends of the connecting rod. A limiting slider is slidably installed at the bottom of the fixing tube. A connecting tube is fixedly connected to the bottom of the limiting slider. A protruding plate is fixedly connected to the surface of the fixing tube. A stop bar is slidably installed inside the protruding plate.

[0015] As a preferred embodiment of the present invention, the connecting tube forms an engaging structure with the fixing tube through the stop bar, and the lower surface of the connecting tube is in contact with the second fixing plate.

[0016] The working principle and beneficial effects of this invention are as follows:

[0017] 1. The moving groove and filling plate on the device keep the steel sheet suspended during the conveying process, so that the device can perform heat fusion connection between the rubber waterstop body and the steel sheet, and keep the rubber covering the upper and lower sides of the steel sheet, thereby improving the firmness of the installation of the rubber waterstop and the steel sheet, and solving the defect of existing extrusion equipment that cannot automatically heat fusion connect rubber and steel sheet.

[0018] 2. By using a cooling assembly, the coolant in the fixed pipe and connecting pipe can be temporarily stored through the screw holes on the surfaces of the first and second fixed plates during the rotation of the connecting shaft and the conveying assembly. This enables rapid cooling of the area where the steel sheet and rubber waterstop are heat-fused together. Furthermore, since the lower surface of the connecting pipe is in contact with the top of the first and second fixed plates, the device can cool the area where the rubber waterstop and steel strip are connected through the screw holes, while also cooling the connecting plate. This improves the cooling effect of the device and solves the problem that existing extrusion devices cannot quickly cool the connection area after automatically heat-fused connection of rubber and steel sheets.

[0019] 3. By using threaded cutting heads mounted on the first and second fixed discs, the device can pre-open the surface of the steel sheet by conveying it before use. This improves the strength of the connection when it is subsequently heat-fused with the rubber waterstop, enhancing the device's functionality and solving the problem of existing extrusion devices that cannot automatically open the surface of the steel sheet using the conveying structure before heat-fusion to ensure a secure connection. The guide assembly ensures the steel sheet remains straight during forward conveying, further improving the strength of the connection between the rubber waterstop and the steel sheet during extrusion.

[0020] 4. By setting the first and second conveyor wheels, the device can support the flat area of ​​the waterstop when conveying the rubber waterstop. Moreover, through the key block, keyway and damping block, the device can adjust the support position of the waterstop, which improves the performance of the device and solves the defect of the existing extrusion device that cannot adaptively adjust the position of the conveyor wheel according to the undulating area and smooth area of ​​the rubber waterstop surface. This device has the advantage of higher adjustability. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] like Figures 1-11As shown, an extrusion device for steel-edged rubber waterstops includes a support base 1, a housing 2 fixedly connected to the top of the support base 1, a first motor 3 fixedly connected to the rear side of the housing 2, a spiral blade 4 fixedly connected to the output shaft of the first motor 3, a feed box 5 fixedly installed on the top of the housing 2, and an electric heating tube 6 fixedly installed in the middle of the spiral blade 4. Rubber raw material is fed into the feed box 5, and the first motor 3 on the housing 2 drives the spiral blade 4 to rotate. As the spiral blade 4 rotates, it conveys the raw material forward. When the electric heating tube 6 is energized, the raw material is molten. A connecting shell 7 is fixedly installed at the front end of the support base 1, and a guide plate 8 is fixedly installed at the front end of the connecting shell 7. Both the connecting shell 7 and the guide plate 8 have internal moving grooves 9. Filling plates 10 are fixedly connected to the left and right sides of the guide plate 8. A rubber waterstop body 11 is installed inside the moving groove 9. Molten rubber material passes through the moving grooves 9 in the connecting shell 7 and the guide plate 8 to form the rubber waterstop body 11. Steel sheets 12 are connected to the left and right sides of the rubber waterstop body 11, and the left and right sides of the rubber waterstop body 11 can cover the upper and lower sides of the steel sheets 12 (in combination). Figures 5-8 As can be seen, the rubber waterstop body 11 inside the device can be firmly connected to the steel sheet 12 during extrusion. Guide components 13 are installed on the left and right sides of the support base 1. The guide components 13 can guide the steel sheet 12, allowing it to move straight back and forth, thus ensuring the production quality of the steel-edged rubber waterstop. A support plate 14 is provided at the front end of the guide plate 8. A first fixing frame 15 is fixedly connected to the left side of the support plate 14, and a second fixing frame 16 is fixedly connected to the right side of the support plate 14. A second motor 17 is fixedly connected to the surface of the second fixing frame 16. A connecting shaft 18 is fixedly connected to the output shaft of the second motor 17. A conveying component 19 is connected to the left side of the connecting shaft 18. A cooling assembly 20 is installed above, and a support plate 14, a first fixed frame 15, and a second fixed frame 16 are used to support the conveying assembly 19 and the cooling assembly 20. The conveying assembly 19 can quickly cool the hot-melt connection area of ​​the rubber waterstop body 11 and the steel sheet 12 through the cooling assembly 20 during the conveying of the steel-edged waterstop. The conveying assembly 19 can also open holes on the surface of the steel sheet 12 by installing a cutter head, so that the rubber waterstop body 11 and the steel sheet 12 can be connected more firmly during subsequent hot-melt connection. The device can adaptively adjust the position of the conveying wheel in the conveying assembly 19 according to the position of the flat section of the steel-edged waterstop surface, thereby improving the applicability of the device.

[0037] Example 2

[0038] like Figures 1-11 As shown, based on the same concept as in Embodiment 1 above, this embodiment also proposes an extrusion device for steel-edged rubber waterstops.

[0039] In this example, the support base 1, the outer shell 2, the connecting shell 7, and the guide plate 8 are integrated into a single unit to ensure the overall stability of the device. The outer shell 2, the connecting shell 7, and the guide plate 8 are interconnected, allowing the rubber raw material to be heated inside the outer shell 2 and then extruded from the connecting shell 7 and the guide plate 8, thereby producing a rubber waterstop.

[0040] In this example, there is a gap between two adjacent filler plates 10. The height of the gap between two adjacent filler plates 10 is equal to the thickness of the steel sheet 12. This ensures that after the steel sheet 12 passes through two adjacent filler plates 10, the part of the steel sheet 12 near the rubber waterstop is in a suspended state, so that the rubber can wrap around the upper and lower sides of the steel sheet 12, thereby improving the firmness of the hot melt connection.

[0041] In this example, the guide assembly 13 includes side plates 1301 fixedly installed on the left and right sides of the support base 1. Fixed plates 1302 are fixedly connected to the front and rear sides of the side plates 1301. A first rotating rod 1303 is installed above the fixed plate 1302, and a second rotating rod 1304 is provided below the first rotating rod 1303. The first rotating rod 1303 and the second rotating rod 1304 are rotatably connected to the fixed plate 1302. The first rotating rod 1303 and the second rotating rod 1304 are symmetrically distributed on the upper and lower sides of the steel strip 12. The first rotating rod 1303 and the second rotating rod 1304 can provide stable support for the upper and lower sides of the steel strip. The side plates 1301 can support the steel strip 12, so that the steel strip 12 can be conveyed straight forward to ensure the production quality of the steel-edged rubber waterstop.

[0042] In this example, the conveying assembly 19 includes a first fixed plate 1901 fixedly installed on the left side of the connecting shaft 18. A second fixed plate 1902 is fixedly connected to the left side of the first fixed plate 1901. Screw holes 1903 are provided around both the first and second fixed plates 1901 and 1902. These screw holes 1903 facilitate subsequent liquid storage, thereby rapidly cooling the heat-melted connection area of ​​the steel-edged rubber waterstop. A punching cutter 1904 is installed inside the screw holes 1903. The punching cutter 1904 can be pre-drilled before heat-melting connection, thus... This ensures a firm connection during heat fusion, improving the stability of the device during operation. A first connecting rod 1905 is fixedly connected to the left side of the second fixed plate 1902, and a first conveying wheel 1906 is fixedly connected to the left side of the first connecting rod 1905. A second conveying wheel 1911 is located below the first conveying wheel 1906, and a second connecting rod 1910 is fixedly installed in the middle of the second conveying wheel 1911. The second connecting rod 1910 is rotatably connected to both the first fixed frame 15 and the second fixed frame 16. The rubber waterstop can be stably conveyed forward through the first conveying wheel 1906 and the second conveying wheel 1911 on the device.

[0043] In this example, the diameter of the second fixing plate 1902 is smaller than the diameter of the first fixing plate 1901. The diameter difference between the first fixing plate 1901 and the second fixing plate 1902 is equal to the height difference between the upper surfaces of the rubber waterstop body 11 and the steel sheet 12. This ensures that the first fixing plate 1901 and the second fixing plate 1902 can fit precisely with the connection area of ​​the rubber waterstop body 11 and the steel sheet 12, thereby achieving the function of pressing after hot melting. This improves the firmness of the device during installation and also facilitates rapid cooling in the future.

[0044] In this example, a keyway 1907 is provided inside the first conveying wheel 1906, a key block 1908 is fixedly connected to the surface of the first connecting rod 1905, and a damping block 1909 is fixedly connected to the surface of the key block 1908. The device can adapt to the flat section of the rubber waterstop for conveying work by adjusting the position of the first conveying wheel 1906, thereby improving the adjustability of the device.

[0045] In this example, the connection between the second conveying wheel 1911 and the second connecting rod 1910 is the same as the connection between the first conveying wheel 1906 and the first connecting rod 1905. The position of the first conveying wheel 1906 corresponds to the position of the first connecting rod 1905. The position of the second conveying wheel 1911 can be adjusted in the same way as adjusting the position of the first conveying wheel 1906, so that the device will not press the protruding part of the rubber waterstop when conveying the rubber waterstop.

[0046] In this example, the cooling assembly 20 includes a connecting rod 2002 fixedly installed between the first fixing frame 15 and the second fixing frame 16. Fixing tubes 2001 are fixedly connected to the outer sides of both ends of the connecting rod 2002. A limiting slider 2004 is slidably installed at the bottom of the fixing tube 2001. A connecting tube 2003 is fixedly connected to the bottom of the limiting slider 2004. A protruding plate 2005 is fixedly connected to the surface of the fixing tube 2001. A stop bar 2006 is slidably installed inside the protruding plate 2005. Figure 11 As shown, the operator can remove the stop bar 2006 inside the protruding plate 2005, so that the connecting pipe 2003 can be removed from below the fixed pipe 2001 through the limiting slider 2004, thereby cleaning the connecting pipe 2003. It can also ensure that the device can work normally when the opening function is used without the cooling function.

[0047] In this example, the connecting pipe 2003 forms an engaging structure with the fixed pipe 2001 through the stop bar 2006. The lower surface of the connecting pipe 2003 is in contact with the second fixed plate 1902. Through the contacting pipe 2003 and the second fixed plate 1902 on the device, the device can cover the surface of the second fixed plate 1902 with the coolant in the connecting pipe 2003, thereby improving the cooling efficiency of the rubber waterstop.

[0048] Specifically, this invention relates to an extrusion device for steel-edged rubber waterstops. First, as follows: Figures 1-8 As shown, during the operation of this device, the entire structure is supported by the support base 1, the connecting shell 7, and the guide plate 8. The first motor 3 drives the spiral blades 4 inside the shell 2 to rotate, conveying the rubber raw material forward. The rubber raw material is heated and melted by the electric heating tube 6, ultimately allowing the rubber raw material delivered to the connecting shell 7 and the guide plate 8 to be extruded and molded, thereby producing the rubber waterstop body 11. The steel sheet 12 is placed on the surface of the side plate 1301, and through the gap between the first rotating rod 1303 and the second rotating rod 1304 on the fixing plate 1302, the steel sheet 12 can be stably conveyed forward. The filling plate 10 in the moving groove 9 supports the steel sheet 12, allowing the upper and lower sides of the portion of the steel sheet 12 near the rubber waterstop body 11 to be thermally fused with rubber, thus ensuring the overall firmness. The device can also install a punching head 1904 in the screw holes 1903 of the first fixed plate 1901 and the second fixed plate 1902. Before hot-melt connection, the device first feeds the steel sheet 12, and then drives the connecting shaft 18 to rotate through the second motor 17 on the second fixed frame 16, which in turn drives the first fixed plate 1901, the second fixed plate 1902 and the punching head 1904 to rotate. This allows the punching head 1904 to process holes on the surface of the steel sheet 12. When processing the holes, the stop bar 2006 in the protrusion plate 2005 needs to be removed, and then the connecting tube 2003 is removed from below the fixed tube 2001 by the limiting slider 2004. This ensures that the first fixed plate 1901 and the second fixed plate 1902 will not be blocked when driving the punching head 1904 to rotate, thus realizing the function of opening holes on the surface of the steel sheet 12. This further improves the firmness of the hot-melt connection of the steel sheet 12.

[0049] like Figure 1 , Figure 4 and Figures 9-11As shown, during operation, by removing the punching head 1904, the screw hole 1903 can store the coolant in the fixing pipe 2001 and connecting pipe 2003 during the rotation of the first fixing plate 1901 and the second fixing plate 1902. Subsequently, the coolant can be sprayed onto the heat-fusion connection between the rubber waterstop body 11 and the steel sheet 12, thereby achieving rapid cooling. When in use, the position of the first conveying wheel 1906 on the first connecting rod 1905 can be adjusted, and the damping block 1909 on the key block 1908 can abut against the keyway 1. The inner wall of 907 enables the adjustment and fixing of the position of the first conveyor wheel 1906. The position of the second conveyor wheel 1911 on the second connecting rod 1910 can be adjusted and fixed in the same way. This allows the device to adaptively adjust the positions of the first conveyor wheel 1906 and the second conveyor wheel 1911 according to the position of the flat section of the rubber waterstop body 11 when conveying the steel-edged conveyor belt, thus avoiding the first conveyor wheel 1906 and the second conveyor wheel 1911 pressing on the protruding section of the rubber waterstop body 11 and causing deformation of the rubber waterstop body 11.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
