Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings 1-2.

A novel section automatic feeding cutting machine comprises a supporting platform 1, a machine frame 2 arranged at the top of one end of the supporting platform 1 and a cutting mechanism 3 arranged at the inner top of the machine frame 2, wherein the supporting platform 1 is provided with feeding mechanisms 4 positioned at two sides of the upstream of the machine frame 2, a section 5 right opposite to the cutting mechanism 3 is clamped between two groups of feeding mechanisms 4, as shown in figure 1, the section 5 is supported by the supporting platform 1 to be in a horizontal state, and the section 5 is clamped and fixed by the two groups of feeding mechanisms 4 and moves leftwards, so that the section 5 and the cutting mechanism 3 are always in a vertical state, the section 5 cut by the cutting mechanism 3 can not be cut obliquely, the secondary cutting and trimming of the cut is not needed, meanwhile, the section 5 is clamped by the two groups of feeding mechanisms 4 and moves leftwards, so that a worker does not need to manually move and load materials, thereby reducing the labor intensity of workers.

Wherein feed mechanism 4 includes vertical two sets of cylinders 41 that set up side by side, and be provided with rubber belt 42 on two sets of cylinders 41, and supporting platform 1 is run through and motor I44 is connected to the axis of rotation 43 bottom of cylinder 41, as shown in fig. 1, motor I44 that is arranged in feed mechanism 4 of rear side drives cylinder 41 through axis of rotation 43 and carries out clockwise rotation, so that drive this rubber belt 42 and carry out clockwise rotation, and motor I44 that is arranged in feed mechanism 4 of front side drives cylinder 41 through axis of rotation 43 and carries out anticlockwise rotation, so that drive this rubber belt 42 and carry out anticlockwise rotation, so with section bar 5 from the right-hand member fill in between two sets of rubber belt 42, pivoted rubber belt 42 can be fixed section bar 4 centre gripping and drive its left movement this moment, with this purpose of realizing automatic feeding and fixed section bar 5.

In order to enhance the friction between the rubber belt 42 and the outer surface of the section bar 5 and prevent the rubber belt from slipping between the two, anti-slip patterns 9 integrally arranged with the rubber belt 42 are vertically arranged on the outer side wall of the rubber belt 42, the friction between the two is enhanced through the anti-slip patterns 9, so that the rubber belt 42 can drive the section bar 5 to move leftwards, a rolling shaft 45 tightly attached to the inner side wall of the rubber belt 42 is vertically arranged between the two groups of rollers 41, and a rotating shaft 43 in the rolling shaft 45 penetrates through the supporting platform 1, so that when the rubber belt 42 rotates, the rolling shaft 45 can abut against the suspended part of the rubber belt 42 to prevent the rubber belt 42 from sinking inwards and can not well clamp and fix the section bar 5, thereby limiting the size of a gap between the two groups of rubber belts 42, enabling the rubber belt 42 to well clamp and fix the section bar 5, and simultaneously, the rolling shaft 45 and the rotating shaft 43 at the bottom end, the resistance of the rolling shaft 45 against the rotating rubber belt 42 is reduced.

As shown in fig. 2, the cutting mechanism 3 in this embodiment includes a fixed frame 31 located in the frame 2 and a cutting wheel 32 located in the fixed frame 31, wherein the top of the frame 2 is provided with an air cylinder 6, and an air cylinder guide post 7 of the air cylinder 6 is fixedly connected with the top end of the fixed frame 31, when the feeding mechanism 4 conveys the profile to a position right below the cutting mechanism 3, the air cylinder 6 drives the fixed frame 31 and the cutting wheel 32 to move downward through the air cylinder guide post 7 so as to gradually reduce the height of the cutting wheel 32, so that the cutting wheel 32 can press on the profile 5 to perform cutting work, and at the same time, in order to enable the cutting wheel 32 to cut off the profile 5, a cutting opening 8 in a quadrangular frustum structure is opened on the supporting platform 1 located right below the cutting wheel 32, as a preferable solution, the minimum opening width of the cutting opening 8 is greater than the thickness of the cutting wheel 32, wherein the minimum opening length of the cutting opening 8 is greater than the diameter of the cutting wheel 32, when the cylinder 6 drives the fixing frame 31 and the cutting wheel 32 to move downwards, the bottom end of the cutting wheel 32 can be inserted into the cutting opening 8, so that the supporting platform 1 cannot abut against the cutting wheel 32 to move downwards, and then after the bottom end of the cutting wheel 32 is inserted into the cutting opening 8, the cutting wheel 32 cuts off the section bar 5.

The reason why the cutting opening 8 is small at the top and large at the bottom in this embodiment is that the cutting chips are not easy to block the cutting opening 8 after falling from the cutting opening 8, but are easy to fall out of the cutting opening 8, and even if a small amount of chips are deposited in the cutting opening 8, the chips inside the cutting opening can be poked out in the process of inserting the cutting wheel 32 into the cutting opening 8.

Preferably, a driving shaft 33 penetrating through the side wall of the fixed frame 31 and connected with a motor II34 is arranged at the center of the circle of the cutting wheel 32, wherein the motor II34 is fixed on the fixed frame 31, and when the profile 5 needs to be cut, the motor II34 drives the cutting wheel 32 to rotate through the driving shaft 33, so as to cut off the profile 5.

As shown in fig. 2, a baffle 10 is arranged at the bottom of the support platform 1, wherein the baffle 10 is positioned at the bottom of the support platform 1 between the motor I44 and the cutting opening 8, so that the safety of the motor I44 is prevented from being affected by the fact that the scraps falling from the cutting opening 8 are easily scattered on the motor I44.

The working principle of the invention is as follows: the motor I44 in the feeding mechanism 4 at the rear side drives the roller 41 to rotate clockwise through the rotating shaft 43, so as to drive the rubber belt 42 to rotate clockwise, and the motor I44 in the feeding mechanism 4 at the front side drives the roller 41 to rotate counterclockwise through the rotating shaft 43, so as to drive the rubber belt 42 to rotate counterclockwise, so that the section 5 is inserted between the two groups of rubber belts 42 from the right end, and at this time, the rotating rubber belt 42 can clamp and fix the section 4 and drive the section 4 to move leftward, so as to achieve the purposes of automatically feeding and fixing the section 5;

when the feeding mechanism 4 conveys the profile to a position right below the cutting mechanism 3, the feeding mechanism 4 stops, the air cylinder 6 drives the fixed frame 31 and the cutting wheel 32 to move downwards through the air cylinder guide post 7 so as to gradually reduce the height of the cutting wheel 32, meanwhile, the motor II34 drives the cutting wheel 32 to rotate through the driving shaft 33, so that the cutting wheel 32 can press on the profile 5 to cut the profile, when the air cylinder 6 drives the fixed frame 31 and the cutting wheel 32 to move downwards, the bottom end of the cutting wheel 32 can be inserted into the cutting opening 8, so that the supporting platform 1 cannot abut against the cutting wheel 32 to move downwards, and then after the bottom end of the cutting wheel 32 is inserted into the cutting opening 8, the cutting wheel 32 cuts off the profile 5;

when the section 5 is cut off, the cutting mechanism 3 resets, and the feeding mechanism 4 drives the section 5 to continuously move leftwards so as to repeat the steps to carry out cutting work.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
