[0023] The following combination Figures 1-11 The present invention describes the production equipment and process of the energy-saving sliding window profile.

[0024] like Figures 1-8 As shown, in one embodiment, a production device and process for an energy-saving sliding window profile includes: A workbench 100, a transmission mechanism 110 is provided on the top of the workbench 100, and a tooth opening mechanism 300 is provided on the top of the workbench 100; The slotting structure 200 includes a slotting component 210 and an auxiliary component 220. The slotting component 210 is disposed on the top of the workbench 100, and the auxiliary component 220 is disposed on the surface of the slotting component 210; Among them, the slotting assembly 210 includes two mounting brackets 2102 fixedly connected to the top of the workbench 100 and symmetrically distributed, and mounting plates 2104 are provided on opposite sides of the two mounting brackets 2102. A driving motor is provided on the top of the mounting plate 2104, and the output shaft of the driving motor passes through the mounting plate 2104 and is fixedly connected to the slotting tool 2101.

[0025] The toothing mechanism 300 and the transmission mechanism 110 are both relatively mature components in the existing technical field and will not be described in detail here. The toothing mechanism 300 can perform toothing on the profile body 400 to strengthen the connection strength between the insulation strip 420 and the profile body 400.

[0026] like Figure 1 、 Figure 2 and Figure 7As shown, a screw rod 2103 is provided inside one of the mounting frames 2102, and one end of the mounting plate 2104 is threadedly connected to the surface of the screw rod 2103; a guide rod 2105 is fixedly connected to the inner wall of the other mounting frame 2102, and the other end of the mounting plate 2104 is slidably connected to the surface of the guide rod 2105.

[0027] A fixed box 2107 is provided on one side of the workbench 100, and a filter plate 2108 is fixedly connected to the inner wall of the fixed box 2107. A first fan 2109 is provided below the filter plate 2108. The top of the fixed box 2107 is connected to a conduit 2106, and the other end of the conduit 2106 passes through the mounting plate 2104 and is connected to a suction nozzle.

[0028] By adjusting the screw rod 2103, the height of the mounting plate 2104 can be adjusted under the limit of the guide rod 2105, so as to facilitate the grooving of profiles of different heights and improve the applicability of the device.

[0029] By starting the first fan 2109, the suction nozzle can generate suction under the action of the first fan 2109 to suck the debris generated during the processing into the inside of the conduit 2106, and introduce it into the internal storage of the fixed box 2107 through the conduit 2106 to facilitate unified cleaning by the staff.

[0030] like Figures 1-8 As shown, the auxiliary component 220 includes two connecting plates 2201, a connecting shell 2205 and a collecting box 2206. The two connecting plates 2201 are fixedly connected to the surface of the mounting plate 2104 and are symmetrically distributed. The connecting shell 2205 is arranged at the bottom of the connecting plate 2201. The collecting box 2206 is detachably arranged inside the connecting shell 2205. The interior of the connecting shell 2205 is provided with a second fan 2204 located above the collecting box 2206.

[0031] A filter is embedded in the top of the collection box 2206, two inlet ports are opened at the bottom of the collection box 2206, and two blocking blocks 2217 are hinged on the inner wall of the collection box 2206 to block the inlet ports.

[0032] The setting of the blocking block 2217 can block the inlet under the action of its own gravity when there is no airflow to prevent the debris inside the collection box 2206 from being discharged through the inlet.

[0033] The bottom of the connecting shell 2205 is fixedly connected to two symmetrically distributed connecting seats 2207, a cavity 2210 is provided inside the connecting seat 2207, and the bottom of the connecting seat 2207 is provided with a dust collection port 2211 that is evenly distributed and connected to the cavity 2210. The upper end of the connecting seat 2207 is connected to a connecting pipe 2208 connected to the connecting shell 2205, and the other end of the connecting pipe 2208 is connected to the cavity 2210.

[0034] Pressure wheels 2209 are provided on opposite sides of the two connecting seats 2207. Both ends of the pressure wheels 2209 are fixedly connected to rotating blocks 2212 that are rotatably connected to the inner wall of the connecting seat 2207. The surface of the rotating block 2212 is provided with evenly distributed limiting grooves 2215, and a side wall of the limiting groove 2215 forms a guiding slope 2216.

[0035] The inner wall of the connecting seat 2207 is slidably connected to the limiting rod 2214, the lower end of the limiting rod 2214 passes through the connecting seat 2207 and extends to the inside of the adjacent limiting groove 2215, and a second spring 2213 is fixedly connected between the upper end of the limiting rod 2214 and the inner wall of the connecting seat 2207.

[0036] The top of the connecting shell 2205 is fixedly connected to two symmetrically distributed adjusting rods 2202. The upper ends of the adjusting rods 2202 pass through the connecting plate 2201 and are fixedly connected to an expansion piece. A first spring 2203 is fixedly connected between the bottom of the expansion piece and the connecting plate 2201.

[0037] By adjusting the height of the mounting plate 2104, the height of the connecting plate 2201 can be adjusted synchronously. Under the action of the first spring 2203, the connecting shell 2205 can drive the connecting seat 2207 to drive the pressure wheel 2209 to fit closely to the position of the bolt groove 410 that needs to be opened on the surface of the profile body 400 through the expansion piece and the adjusting rod 2202. After the groove is opened, one of the pressure wheels 2209 can be driven to insert into the inside of the bolt groove 410 under the action of the first spring 2203. By starting the second fan 2204, the debris inside the bolt groove 410 can be sucked into the interior of the connecting shell 2205 through the dust collecting port 2211, the cavity 2210 and the connecting pipe 2208. The blocking block 2217 of the collection box 2206 is lifted up under the push of the airflow, so that the debris is collected inside the collection box 2206 for easy cleaning by the staff, avoiding the problem that the inside of the bolt groove 410 is blocked by the groove tool 2101 and is inconvenient to clean.

[0038] During the transportation of the profile body 400, the pressure wheel 2209 can drive the pressure wheel 2209 to rotate through friction. During this process, the pressure wheel 2209 drives the rotating block 2212 to rotate, so that the guiding inclined surface 2216 pushes the lower end of the limit rod 2214 to move it upward and compress the second spring 2213 until the next limit groove 2215 moves to the limit rod 2214, and then it can be driven to reset and insert into the inside of the limit groove 2215 under the action of the second spring 2213. The other side wall of the limit groove 2215 and the limit rod 2214 cooperate with each other to prevent the pressure wheel 2209 from reversing, and the friction with the profile body 400 is increased when the profile body 400 slides in the opposite direction, thereby reducing the possibility of the profile body 400 moving in the opposite direction and improving safety.

[0039] Furthermore, applying pressure to the profile body 400 using the pressure wheel 2209 during operation can make the profile body 400 more stable, thereby improving stability during processing.

[0040] A production process for energy-saving sliding window profiles comprises the following steps: S1. Place the formed profile body 400 on the transmission mechanism 110 and perform a slotting process on it using the slotting mechanism 300. The slotted profile body 400 can improve the connection strength with the thermal insulation strip 420. S2. During the toothing process, the profile body 400 is slotted with the bolt slot 410 through the slotting structure 200. The heat insulation strip 420 can be further limited by reinforcing bolts or screws to increase the connection strength of the thermal insulation aluminum profile. S3. After the slotting is completed, the heat insulation strip 420 made of rigid polyurethane foam composite nylon 66 material is installed in the installation slot after the toothing process according to production requirements. After the installation is completed, the profile body 400 and the heat insulation strip 420 are pressed and fastened using a pressing machine. The heat transfer coefficient of the polyurethane composite nylon 66 thermal insulation core is 0.058 W / ㎡·K, which helps to improve the energy saving coefficient of the composite thermal insulation window. At the same time, the use of polyurethane rigid foam material helps to soundproof the entire window, which effectively meets the needs of green buildings and ultra-low energy consumption buildings for doors, windows and curtain walls. S4. After the press-fitting is completed, the reinforcing bolts or screws are passed through the insulation strip 420 to the inside of the bolt groove 410, and they are tightened before installing the decorative cover plate 430. The arrangement of the reinforcing bolts or screws passing through the insulation strip 420 can be connected to the indoor and outdoor aluminum alloys to strengthen the structural strength of the opening sash and ensure that the window sash supports the glass.
