Description

Technical Field

[0001] This utility model relates to the technical field of window frame processing equipment, and more specifically, to an environmentally friendly hot melt device for processing PVC window frames. Background Technology

[0002] PVC profiles refer to PVC profiles used to make doors and windows. Because doors and windows made solely of PVC profiles are not strong enough, steel is usually added inside the cavity to enhance their sturdiness. Therefore, plastic doors and windows made with steel added inside the profile are usually called PVC doors and windows. With the widespread use of PVC doors and windows, the PVC profiles used to make them are commonly referred to as PVC profiles. When using PVC profiles to process window frames, a hot-melt process is generally used.

[0003] In existing technologies, when heat-melting PVC window frames, a heating plate is generally used to heat the corners of the PVC window frame and melt them. The molten part is then piled up to facilitate the connection of the window frame. This process generates harmful gases, which, if not treated, will affect air quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the exhaust gas generated during the hot melting of PVC window frames affects air quality, and to design an environmentally friendly hot melting device for the processing of PVC window frames.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] This utility model provides, for example Figures 1-6 An environmentally friendly hot-melt device for processing PVC window frames is shown, comprising a workbench 1, a telescopic frame 2 that can move the window frame is installed on the workbench 1, support platforms 3 are bolted to the four corners of the upper surface of the workbench 1, a protective box 4 is provided above the support platform 3, a lifting frame 5 is installed on the support platform 3, the lifting frame 5 can move the protective box 4 up and down, the protective box 4 has long openings 6 on the two side surfaces near the telescopic frame 2, a telescopic sealing plate 7 is installed at the long openings 6, the sealing plate 7 has a notch 8 corresponding to the window frame, a liftable heating plate 9 is installed at the upper end of the protective box 4, and a purifier 10 is connected to one side of the protective box 4.

[0021] The process of heat-melting the window frame using this device is as follows: The protective box 4 is lifted by the lifting frame 5, and then the window frame is placed on the telescopic frame 2. The movement of the telescopic frame 2 moves the window frame. Then, the lifting frame 5 moves the protective box 4 downward, covering the window frame through the notch 8. Then, the heating plate 9 is moved to the connection point of the window frame. The telescopic frame 2 moves the window frame, and the connection point of the window frame moves to the heating plate 9. The heating plate 9 heats the window frame, which produces harmful gases. The purifier 10 treats the harmful gases, and then the heating plate 9 returns to its original position. The telescopic frame 2 moves the window frame and the sealing plate 7, making it easier to splice the window frames together. After the window frames cool down, they are joined together. The lifting frame 5 lifts the protective box 4, and then the window frame is removed.

[0022] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Included with instruction manual Figure 5 The protective box 4 has an inlet / outlet 11 at the top, and a square sleeve 12 is installed inside the inlet / outlet 11. A lifting block 13 is installed inside the square sleeve 12. A heating plate 9 is installed on the lower surface of the lifting block 13. A sealing gasket 14 is installed at the lower end of the protective box 4. The protective box 4 is not equipped with a sealing gasket 14 at the position of the long opening 6. The lifting block 13 can move up and down inside the square sleeve 12 to ensure the direction of movement of the lifting block 13. The sealing gasket 14 can block the gap between the protective box 4 and the support platform 3, thereby preventing the leakage of harmful gases.

[0023] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 The lifting frame 5 includes a lifting platform 15 located above the protective box 4. The lifting platform 15 is connected to the support platform 3 via an electric telescopic rod 16. The lifting platform 15 and the lifting block 13 are connected via a connecting rod 17. The upper and lower ends of the square sleeve 12 are equipped with intercepting plates 18. The lifting block 13 and the lower intercepting plate 18 are connected via a telescopic spring 19. The square sleeve 12 is equipped with a limit plate 20.

[0024] The process of the lifting frame 5 moving the protective box 4 up and down is as follows: Under normal conditions, the protective box 4 is located above the support platform 3. The electric telescopic rod 16 is activated to shorten. The electric telescopic rod 16 can drive the lifting block 13 to move downward through the connecting rod 17. The lower intercepting plate 18 can be moved downward through the telescopic spring 19, and the square sleeve 12 and the protective box 4 can be moved downward, so that the protective box 4 can fall on the support platform 3. When the lifting block 13 falls on the limiting plate 20, the heating plate 9 can be limited. After heating is completed, the electric telescopic rod 16 is activated to shorten, which can drive the lifting platform 15, the connecting rod 17, and the lifting block 13 to move upward. Under the elastic force of the telescopic spring 19, the protective box 4 can be prevented from moving upward, which can ensure the sealing effect. After the window frame is connected, the lifting block 13 is moved upward again. When the upper end of the lifting block 13 contacts the upper intercepting plate 18, the protective box 2 can be moved upward.

[0025] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Instruction manual attached Figure 4 Included with instruction manual Figure 6 The sealing plate 7 is located inside the protective box 4. A guide block 21 is installed on the upper end of the sealing plate 7. A guide slide 22 is installed on the inner surface of the protective box 4 above the guide block 21. The upper end of the guide block 21 extends into the guide slide 22. A sealing strip 23 is installed on the side of the sealing plate 7 near the inner surface of the protective box 4. The sealing plate 7 and one side surface of the protective box 4 are connected by a return spring 24. When the window frame extends into the inside of the sealing plate 7 from the notch 8, the sealing plate 7 can be moved when the window frame is moved, and the return spring 24 is stretched. The sealing strip 23 can prevent the leakage of harmful gases. After the protective box 4 is pulled up, the sealing plate 7 can be pulled up. When the sealing plate 7 is separated from the window frame, the sealing plate 7 can return to its original position under the pulling force of the return spring 24.

[0026] Refer to the instruction manual appendix Figure 1 The purifier 10 includes an exhaust fan 25 installed on the protective box 4. An air inlet pipe 26 is installed at the inlet end of the exhaust fan 25, which extends into the protective box 4. An air processor is connected to the outlet end of the exhaust fan 25 through an air outlet pipe 27. When the exhaust fan 25 is started, harmful gases in the protective box 4 can be extracted through the air inlet pipe 26 and then discharged into the air processor through the air outlet pipe 27, thereby treating the harmful gases.
