Technical Field

[0001] The utility model belongs to the technical field of plastic material processing, and in particular relates to a plastic material cutting and sawing processing device. Background Art

[0002] Plastic sheets are widely used. When processing and using plastic sheets, a cutting machine is needed to cut the plastic sheets. At present, most plastic sheets are placed on a simple bracket or sawing machine, and the plastic sheets are manually pushed for sawing. It is very easy for the operator's hand to be injured by the saw blade due to manual operation errors. The safety and cutting efficiency are low, which is not conducive to safe production. Another sawing method is to fix the plastic sheet on a simple bracket and cut it manually with a handheld saw. During the cutting process, the operator needs to control the sawing trajectory based on experience, which is prone to uneven cutting surfaces, and even requires secondary cutting, resulting in low cutting efficiency.

[0017] The clamping and positioning mechanism includes a clamping guide rail 13, a clamping slider group 14, a lifting mechanism, and a clamp 19. Two clamping guide rails 13 are axially symmetrically arranged on the upper surface of the workbench 2 on both sides of the saw groove 3. A clamping slider group 14 matching the clamping guide rail 13 is arranged.

[0018] Each of the clamping slider groups 14 includes two clamping sliders 15 , and the two clamping sliders 15 of the clamping slider group 14 are sequentially arranged on the same clamping guide rail 13 .

[0019] The lifting mechanism includes a rocker 16, a support beam 17, and a folding tripod 18. The support beam 17 is arranged between the two clamping guide rails 13 and is perpendicular to the clamping guide rails 13. The two ends of the support beam 17 are respectively connected to the clamping slider 15 on the same side. Specifically, the support beam 17 is arranged between any two opposite clamping sliders 15 on the two clamping guide rails 13 on the same side of the saw groove 3, and the support beam 17 is not arranged between the other two opposite clamping sliders 15. The rocker 16 is axially arranged between the two clamping guide rails 13, and one end thereof extends to the side of the saw groove 3. It is connected with a support, and the other end passes through the support beam 17 in turn, and a rocker is extended out of the workbench 2 to set the rocker. The rocker 16 is threadedly connected to the support beam 17. The clamping slider 15 is reciprocated on the two clamping guide rails 13 by rotating the rocker 16. The folding tripod 18 is arranged on the two clamping sliders 15 of the clamping slider group 14, and the two clamping sliders 15 are connected as a whole. The lower end of the folding tripod 18 is movably hinged to each clamping slider 15. The movable hinge setting can avoid motion interference and improve the flexibility of use and adjustment.

[0020] The clamp 19 includes a main plate 20, a secondary plate 21, a limiting rod 22, and a spring 23. The main plate 20 is movably hinged at the top of the two folding tripods 18, the secondary plate 21 is arranged on the main plate 20 through the limiting rod 22, the spring 23 is arranged on the limiting rod 22 between the main plate 20 and the secondary plate 21, and the limiting rod 22 is threadedly connected to the main plate 20 and the secondary plate 21.

[0021] An adjustment scale 24 is provided on the outer side wall of the clamping guide rail 13 .

[0022] The folding tripod 18 is arranged in a herringbone structure, and the two legs at the lower end thereof are respectively movably hinged to the clamping slider 15. The two folding tripods 18 on the same side share a hinge axis. When the height of the clamp 19 needs to be raised or lowered, the clamping slider 15 without the support beam 17 is pushed to move, so that the two legs of the folding tripod 18 can be folded or opened, thereby realizing the height adjustment of the folding tripod 18.

[0023] The dust collecting mechanism includes a collecting trough 25, a collecting box 26, an exhaust fan 27 and a filter plate 28. The collecting trough 25 is configured to be a trough box structure with an open top and a V-shaped bottom. The collecting trough 25 is upwardly covered on the saw groove 3 and is fixedly connected to the frame 1 or the table by a bracket. The width and length of the collecting trough 25 are matched with the size of the saw groove 3. A through hole for the rotating shaft to pass through is provided on the collecting trough 25 corresponding to the saw machine 6. A collecting box 26 is provided on one side of the bottom of the collecting trough 25, and an exhaust fan 27 is provided on one side of the collecting box 26. The collecting trough 25, the collecting box 26 and the exhaust fan 27 are connected by a pipeline, and the filter plate 28 is provided between the collecting box 26 and the exhaust fan 27.

[0024] The working method of the utility model is as follows: 1. Determine the length and sawing position of the plastic profile such as the plate, bar, etc. to be sawed, rotate the two rockers 16 respectively, or rotate only one of the rockers 16 to adjust the distance between the clamps 19 on both sides of the saw groove 3, and then place the plastic profile on the two clamps 19 for clamping and fixing;

[0025] 2. Start the sawing machine 6. During the rotation of the sawing machine 6, the transmission gear 11 on its rotating shaft will drive the intermediate gear 12 to rotate, and then drive the transmission shaft 8 to rotate. The speed of the transmission shaft 8 is regulated by the transmission 10 to drive the driving gear 9 to rotate, so that the driving gear 9 moves on the driving rack 7, and finally drives the feed slider 5 to move on the feed guide rail 4, so that the sawing machine 6 can automatically move the feed cutting depth or distance while cutting the plastic profile, thereby solving the problem of manually moving the sawing machine 6 or the plastic profile for cutting, and realizing automatic moving cutting operation.

[0026] 3. During the sawing process, the exhaust fan 27 is started to suck the collection slot 25, and the debris and dust generated by the saw blade 29 during the sawing process are sucked into the collection box 26 for temporary storage to prevent splashing into the air. The filtration realizes gas-matter separation to avoid the debris being sucked into the exhaust fan 27.

[0027] 4. During sawing, when it is necessary to adjust the height of the plastic profile, that is, to only cut a saw groove 3 on the plastic profile without cutting it off, manually push the clamping slide block 15 without the support beam 17 installed to move, so that the two legs of the folding tripod 18 can be folded or opened, thereby adjusting the height of the folding tripod 18, and finally adjusting the height between the plastic profile and the saw blade 29. After adjustment, since the two legs of the folding tripod 18 are hinged through a hinge shaft, nuts are set at both ends of the hinge shaft to limit the position and prevent it from falling off. Therefore, the friction between the two can be used to limit the position, or the nuts on the hinge shafts of the two legs can be rotated to tighten them to prevent the two legs from being opened and lowered due to force. In this way, the height of the lifting mechanism on both sides of the saw groove 3 can be adjusted respectively.

[0028] 5. When it is necessary to cut a bevel groove or bevel edge on the plastic profile, according to the adjustment operation method of step 4, only the height of the lifting mechanism on either side of the saw groove 3 is adjusted to make a height difference between the two lifting mechanisms, so that the plastic profile can be tilted to facilitate cutting of the bevel groove or bevel edge.
