The prior art includes the following modes for cutting off the aluminum profile: an aluminum profile fixed-length cutting system is disclosed in patent application 201320597067.9, which adopts an automatic fixed-length cutting mode. Specifically, a length measuring wheel encoder connected with the length measuring wheel is used for sending pulses with a certain frequency, counting is carried out through a high-number counter of a PLC, the displacement and the speed of the aluminum profile are calculated in real time, when the displacement reaches a set value, the PLC sends speed signals, the servo motor encoder sends the pulses to control a servo motor to work, a driver starts the servo motor to work, a cutting vehicle and the aluminum profile run synchronously, and the length of single feeding of the aluminum profile is adjusted and the cutting length is adjusted. By starting the hold-down device and the air inlet valve; the position of the aluminum profile is limited by clamping the pressing device, and the saw blade (cutting knife) moves up and down by pushing the air inlet valve so as to cut the aluminum profile.

According to the technical principle, the automatic fixed-length cutting mode in the prior art mainly comprises three motion modules, an automatic feeding module, a pressing module and a cutting module, the three modules are independent from each other, and motion coordination among the three modules is realized through a numerical control center coding program. Because the feeding module, the compressing module and the cutting module in the aluminum profile fixed-length cutting system are mutually independent, the device has poor integration effect, heavy whole device and poor mobility (generally, the device is fixed in a factory and is inconvenient to transfer, disassemble and install); in addition, the mode that adopts the numerical control on the one hand the cost is high, and on the other hand, when the deviation appears in the signal, need readjust the procedure, the later maintenance is troublesome, also does not benefit to the little enterprise that gives first place to with little processing in batches and uses.

Also, as disclosed in patent application 201820969095.1, a cutting machine for cutting aluminum profiles for industrial use, and patent application 201210206625.4, the technology employs a manual cutting method. Specifically, utilize the motor to drive the cutting wheel and rotate, push down through cutting wheel (cutting knife), carry out cutting work to the aluminium alloy, carry out spacing centre gripping to the aluminium alloy through removing stopper cooperation connecting block.

Furthermore, because the side surface of the clamping part is fixedly connected with the contact plate, when the clamping device is used, the telescopic part can be stretched relative to the fixing part by loosening the locking bolt, so that the length of the contact plate can be adjusted. Because the position of the pushing rack in the width direction is fixed, when the width of the aluminum profile changes, the pushing rack may not be in contact with the clamping part in the moving process, and further the feeding movement of the clamping part cannot be realized, a contact plate is fixedly connected to the side surface of the clamping part, the length of the contact plate is adjustable, the requirements of the widths of different aluminum profiles are met, and the pushing rack is guaranteed to be in contact with the clamping part in the moving process.

Further, a rubber ring is arranged between the translation screw rod and the conveying channel, the translation screw rod is sleeved with the rubber ring, the rotation friction of the translation screw rod is increased through the rubber ring, and the external force required by the rotation of the translation screw rod is increased; when a non-tooth section (an outer convex arc, namely an outer locking arc) of the incomplete gear is contacted with an inner concave arc (namely an inner locking arc) of the linkage gear, the function of doubly fastening the linkage gear is achieved by utilizing the mutual matching of the locking arcs of the rims of the incomplete gear and the linkage gear and the friction resistance of the rubber ring, and the position stability of the translation screw rod in the state is ensured; or when the locking arc does not exist between the incomplete gear and the linkage gear for locking, if the incomplete gear is a sector gear and the tooth section of the incomplete gear is not meshed with the linkage gear, a gap exists between the incomplete gear and the linkage gear, the frictional resistance of the rubber ring is utilized to ensure the position stability of the translation screw rod in the state. Of course, the inner concave arc of the linkage gear can also be positioned at the top of the teeth, and after the last tooth of the tooth section of the incomplete gear is separated from the teeth of the linkage gear, the non-tooth section of the incomplete gear is matched with the inner concave arc of the next tooth of the linkage gear to lock the linkage gear.

Further, after the aluminum section is cut off, the rotating arm is driven to rotate through the reset rotation (upward rotation) of the connecting piece, the ejector rod is driven to move upwards through the transmission of the connecting rod, the ejector rod moves upwards to push the cut aluminum section upwards to incline the cut aluminum section, the end plate rotating part rotates, the elastic piece deforms, the cut aluminum section inclines and falls under the action of gravity, automatic blanking is realized, the elastic piece of the end plate rotating part resets, and the end plate rotating part resets.

The support effect of the support plate can prevent the stability of the cutting process from being influenced by the overlong length of the end part of the aluminum profile suspended at the cutting opening; and the normal blanking of the cut aluminum profile can not be influenced due to the existence of the supporting plate. The continuous motion can be realized only by rotating the connecting piece, so that the device has extremely high operability and operation convenience, and the integration and cooperation of the device are further improved.
