Description

Technical Field

[0001] This utility model relates to a plastic door and window cutting platform, belonging to the field of door and window cutting technology. Background Technology

[0002] Plastic doors and windows are made from plastic profiles. They possess excellent properties such as waterproofing, wind resistance, and heat insulation. During the production of plastic doors and windows, the main profiles, after extrusion and shaping, need to be cut. Current cutting devices use a vertically lifting cutting machine to cut the plastic door and window profiles conveyed by a transport mechanism. However, the current transport mechanism lacks a positioning and guiding structure, causing the main profiles to easily become skewed during transport, resulting in beveled cut surfaces and affecting cutting accuracy.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1, as Figures 1 to 3As shown, this utility model is a plastic door and window cutting platform, including a base plate 2. A cutting saw blade 10 is provided above the middle of the base plate 2. The cutting saw blade 10 is connected to a cutting motor 15. A cutting frame 12 is fixed on the base plate 2. A lifting mechanism is installed on the cutting frame 12. The lifting mechanism is connected to the cutting motor 15. At least one set of positioning and guiding mechanisms are provided on both the left and right sides of the cutting motor 15. Each set of positioning and guiding mechanisms includes an upper pressure roller 5 and a lower support roller 20. The upper pressure roller 5 is connected to a height adjustment mechanism one, and the lower support roller 20 is connected to a height adjustment mechanism two. A positioning ring platform 22 is provided on the outer side wall of the lower support roller 20, which is coaxial with it and cooperates with the bottom opening of the main profile of the plastic door and window. A conical clearance platform is provided on the outer side wall of the positioning ring platform 22.

[0020] During operation, the cutting motor 15 starts, driving the cutting saw blade 10 to rotate. The plastic door and window main profile extruded by the extrusion molding machine is conveyed between the upper pressure roller 5 and the lower support roller 20 of the leftmost set of positioning and guiding mechanisms. At this time, the positioning ring platform 22 on the leftmost lower support roller 20 extends into the bottom opening of the plastic door and window main profile for positioning and guidance. Then the plastic door and window main profile is conveyed to the cutting position. When the cutting length is reached, the conveying of the plastic door and window main profile stops. The lifting mechanism drives the rotating cutting saw blade 10 to move downward and then cuts the plastic door and window main profile. After cutting, the lifting mechanism drives the rotating cutting saw blade 10 to rise, and then the plastic door and window main profile continues to be conveyed.

[0021] Example 2, based on Example 1, includes an adjustment bracket 3. A vertical adjustment slide rail 25 is fixed to the adjustment bracket 3. An adjustment slider is mounted on the adjustment slide rail 25. A vertical adjustment nut 19 is fixed to the adjustment slider. The adjustment nut 19 is connected to an adjustment screw 4, which is rotatably mounted on the adjustment bracket 3. A horizontal support shaft 1 is fixed to the inner side of the adjustment nut 19. An upper pressure roller 5 is rotatably mounted on the support shaft 1. Before operation, the adjustment screw 4 can be rotated to move the adjustment nut 19 up and down, which in turn moves the adjustment slider up and down along the adjustment slide rail 25, thus moving the upper pressure roller 5 up and down to adjust its height.

[0022] The height adjustment mechanism includes an adjustment bracket 6, on which a vertical adjustment slide rail 23 is fixed. An adjustment slider 2 is mounted on the adjustment slide rail 23, and a vertical adjustment nut 2 is fixed on the adjustment slider 2. The adjustment nut 2 is connected to an adjustment screw 21, which is rotatably mounted on the adjustment bracket 6. A horizontal support shaft 2 is fixed to the inner side of the adjustment nut 2, and the lower roller 20 is rotatably mounted on the support shaft 2. Before operation, the adjustment screw 21 can be rotated to move the adjustment nut 2 up and down, which in turn moves the adjustment slider 2 up and down along the adjustment slide rail 23, thus moving the lower roller 20 up and down to adjust its height.

[0023] Both the first adjusting bracket 3 and the second adjusting bracket 6 are equipped with a front-to-back adjusting mechanism at their bottoms. This mechanism includes an adjusting slide plate 16 fixed to the bottom of each bracket. A movable slider is fixed to the bottom of the adjusting slide plate 16, and the movable slider is connected to a movable slide rail 17. A mounting plate 9 is fixed to the bottom of the movable slide rail 17 and is mounted on the base plate 2. A movable screw 18, parallel to the movable slide rail 17, is rotatably mounted on the mounting plate 9. The movable screw 18 is connected to a movable nut, which is fixed to the adjusting slide plate 16. Before operation, the movable screw 18 can be rotated to move the movable nut back and forth, thereby moving the movable slider along the movable slide rail 17. This adjusts the front-to-back position of the upper pressure roller 5 and the lower support roller 20, aligning the positioning ring 22 on the lower support roller 20 with the bottom opening of the main profile of the plastic door and window.

[0024] A support plate 8 is fixed to the inner side of the adjusting bracket 3. The bottom of the support plate 8 is fixed to the adjusting slide plate 16. The support plate 8 is provided with a strip hole through which the support shaft 1 passes and moves up and down. A rotating handwheel is fixed to the outer end of the moving screw 18.

[0025] T-shaped sliders 24 are fixed to the front and rear sides of the bottom of the mounting plate 9. The top of the front and rear sides of the base plate 2 is provided with T-shaped grooves along the left and right direction. Locking bolts are threaded onto the mounting plate 9. Before operation, the locking bolts can be loosened as needed, and then the left and right positions of the mounting plate 9 can be adjusted to adjust the left and right positions of the positioning guide mechanism. After adjustment, the locking bolts are tightened.

[0026] The lifting mechanism includes a cutting cylinder 11 fixed on the cutting frame 12. The bottom piston rod of the cutting cylinder 11 is fixed with a mounting frame 14. The cutting motor 15 is fixed on the mounting frame 14. The cutting cylinder 11 has symmetrical guide rods 13 on both sides.

[0027] A vertical limiting cylinder is fixed to the middle of the right side of the mounting plate 9 on the far right, and a limiting baffle 7 is fixed to the top of the limiting cylinder. When the main plastic door and window profile is conveyed to the right, the limiting cylinder extends, the limiting baffle 7 extends, and the end of the main plastic door and window profile is positioned for fixed-length cutting. After the cutting is completed, the limiting cylinder retracts, the limiting baffle 7 descends, and the cut main plastic door and window profile is conveyed out.
