[0035] Wherein, the saw blade 102 is provided with a circular opening for the output shaft of the motor 201a to pass through, two limiting rings are further arranged on the output shaft of the motor 201a, the limiting ring at the outer end is threadedly connected with the output shaft of the motor 201a, so that the saw blade 102 can be limited between the two limiting rings, and the saw blade 102 is convenient to replace, which is prior art and will not be described herein, and the first wedge-shaped block 203j is arranged to avoid the phenomenon that the third ring 203d is stuck when abutting against the first wedge-shaped block 203j.

[0036] Preferably, the gear assembly 204 comprises a transmission shaft 204a rotatably connected to the support base 101, the transmission shaft 204a is fixedly connected with a gear 204b, the support base 101 is provided with a T-shaped port 204c, the T-shaped port 204c is slidably connected with a toothed plate 204d engaged with the gear 204b, the toothed plate 204d is fixedly connected with an adapter plate 204e, the adapter plate 204e is elastically connected with the support base 101 through a third spring 204f, the adapter plate 204e is fixedly connected with the U-shaped frame 104, the fourth circular ring 203e is provided with a gear ring 204g matched with the gear 204b, the motor 201a is fixedly connected with a stop ring 204h, the fourth circular ring 203e is fixedly connected with a connecting rod 204i, the connecting rod 204i is fixedly connected with an anti-off block 204j, the stop ring 204h is provided with an anti-off groove 204k matched with the anti-off block 204j.

[0037] It should be explained that the T-shaped port 204c is arranged to ensure the smooth sliding of the toothed plate 204d, in the embodiment, the number of the gear ring 204g is one, and the gear ring 204g is fixedly connected with the gear ring 204g, and the gear ring 204g is provided with only one tooth, the inclined surface of the second wedge-shaped block 206c faces the right end, so that the toothed plate 204d is not blocked when moving to the right, and the width of the second transverse groove 205d is greater than the width of the first transverse groove 205b, so as to ensure that there is enough space to accommodate the cylinder 205h and the second wedge-shaped block 206c.

[0038] In use, first, the profile is placed in the U-shaped clamp 105, then the position to be cut is aligned with the reference line, then the profile is fixed by rotating the screw rod 106, the handle is arranged on the screw rod 106 to facilitate the rotation of the screw rod 106, and the lower end of the screw rod 106 can also be fixed with a pad to avoid scratching the profile when the screw rod 106 is tightened for cutting, then the motor 201a is turned on, the output shaft of the motor 201a rotates to drive the saw blade 102 to rotate, when the output shaft of the motor 201a rotates, the rigid rope 202g can rotate around the output shaft (the output shaft of the motor 201a, the same below, the output shaft of the motor 201a is prior art and will not be described here), so that the steel ball 202h rotates around the output shaft of the motor 201a, and then the speed of the output shaft of the motor 201a becomes faster and faster, and then reaches a stable value, under the action of centrifugal force, the rigid rope 202g slowly changes from an inclined state to a vertical state, in this process, the steel ball also moves with the rigid rope 202g, so that the arc-shaped plate 202c moves towards the second circular ring 203a, the arc-shaped block 202e moves towards the second circular ring 203a, and the connecting sleeve 203c moves towards the second circular ring 203a, so that the third circular ring 203d is clamped into the annular groove 203b of the second circular ring 203a; When the third ring 203d has not entered the annular groove 203b of the second ring 203a, the fourth ring 203e is in a separated state with the second ring 203a, and the ball 203g rotates between the outer circle of the second ring 203a and the inner circle of the fourth ring 203e. At this time, the rotation of the second ring 203a does not drive the rotation of the fourth ring 203e. As the rotation speed of the motor 201a gradually increases to be stable, the third ring 203d is slowly moved to the annular groove 203b through transmission. When the third ring 203d is clamped into the annular groove 203b of the second ring 203a, the first wedge block 203j is pushed to move in the direction of the square bar 203i, so that the ball 203g has a tendency to move outward. At this time, if the ball 203g is not directly opposite the semicircular groove 203f on the inner wall of the fourth ring 203e, the ball 203g contacts the inner wall of the fourth ring 203e. At this time, the second spring 203k is compressed to avoid the phenomenon of being stuck. At the same time, the damping between the anti-extraction block 204j and the anti-extraction groove 204k is provided, and the ball 203g is rotationally connected with the square block. Even if the ball 203g abuts against the inner wall of the fourth ring 203e, the fourth ring 203e cannot be driven to rotate. With the rotation of the second ring 203a, when the ball 203g is directly opposite the semicircular groove 203f, the ball 203g enters the semicircular groove 203f under the action of the second spring 203k. At this time, the rotation of the second ring 203a drives the rotation of the fourth ring 203e, so that the gear ring 204g rotates to drive the gear 204b to rotate, so that the toothed plate 204d moves to drive the U-shaped frame 104 to move, so that the profile moves to the saw blade 102 to realize automatic cutting. Since only when the rotation speed of the motor 201a reaches a certain speed, the third ring 203d can be clamped into the annular groove 203b of the second ring 203a, so that the saw blade 102 only starts cutting when it reaches a certain speed, avoiding the problem that the insufficient rotation speed of the saw blade 102 affects cutting.

[0039] In summary, by setting the conveying component 200, the profile is only fixed on the U-shaped clamp 105, and then the motor 201a is started to automatically feed and cut, without the need for manual feeding by workers, protecting the safety of workers. The feeding process is started after the stable rotation of the saw blade 102, avoiding the problem that the insufficient rotation speed of the saw blade 102 affects cutting.

[0040] Embodiment 2, refer to Figures 1-5For the second embodiment of the present application, unlike the previous embodiment, the embodiment provides a resetting assembly 205 of the profiled material lower exit saw cutting device, solves the problem of how to reset the profiled material, and comprises the resetting assembly 205, the guide plate 205a fixedly connected to the lower end face of the table top 103, the first horizontal slot 205b arranged on the guide plate 205a, the arc-shaped slot 205c arranged in communication on the first horizontal slot 205b, the second horizontal slot 205d arranged on the arc-shaped slot 205c, the resetting slot 205e arranged in communication on the second horizontal slot 205d and in communication with the first horizontal slot 205b, the support slot 205f arranged on the adapter plate 204e, the support block 205g fixedly connected to the toothed plate 204d and matched with the support slot 205f, and the cylinder 205h arranged in the first horizontal slot 205b. The one-way assembly 206 comprises the positioning slot 206a arranged in the first horizontal slot 205b, the inner recess 206b arranged on the cylinder 205h, the second wedge-shaped block 206c slidably connected in the inner recess 206b and matched with the positioning slot 206a, and the resetting spring 206d elastically connected between the second wedge-shaped block 206c and the inner wall of the inner recess 206b.

[0041] Specifically, the width of the resetting slot 205e is greater than the width of the first horizontal slot 205b, so that when the cylinder 205h moves into the second horizontal slot 205d, the phenomenon of being stuck does not occur due to insufficient width, and the second wedge-shaped block 206c is arranged to avoid the phenomenon of being stuck between the wedge-shaped block and the inner recess 206b.

[0042] In use, in the process of automatic cutting when the gear 204b rotates to drive the toothed plate 204d to move rightward, the cylinder 205h first slides in the first horizontal groove 205b, in this process, the oblique edge of the wedge-shaped block cooperates with the inner wall of the positioning groove 206a, and then cooperates with the return spring 206d, so that when the wedge-shaped block moves rightward, it will not be blocked, and when it moves leftward, since the non-oblique surface of the wedge-shaped block abuts against the inner wall of the positioning groove 206a, the cylinder 205h will not move leftward when moving in the first horizontal groove 205b, thereby avoiding the automatic resetting of the profiled bar when the teeth of the gear ring 204g are not engaged with the teeth of the gear 204b. In the process of movement of the toothed plate 204d, the third spring 204f is elongated to obtain elasticity, and when the profiled bar moves to the right side of the saw blade 102, the cylinder 205h moves to the connection between the first horizontal groove 205b and the arc-shaped groove 205c, at this time, the toothed plate 204d does not disengage from the gear 204b, and the toothed plate 204d continues to move rightward to drive the cylinder 205h to move rightward, so that the cylinder 205h moves into the arc-shaped groove 205c, and when the cylinder 205h moves to the connection between the arc-shaped groove 205c and the second horizontal groove 205d, the toothed plate 204d disengages from the gear 204b, at this time, under the action of the third spring 204f, the cylinder 205h enters the second horizontal groove 205d and resets through the second horizontal groove 205d to drive the toothed plate 204d to reset, drive the adapter plate 204e to reset, so that the U-shaped frame 104 resets to drive the profiled bar to reset, at this time, since the resetting is driven by the third spring 204f, the resetting speed is relatively fast, so as to save the cutting time. In the process of lifting of the toothed plate 204d, the supporting groove 205f cooperates with the supporting block 205g to avoid the phenomenon that the toothed plate 204d cannot move upward, when the third spring 204f is about to completely reset, the cylinder 205h enters the reset groove 205e, which is also arc-shaped and communicates with the first horizontal groove 205b, finally, the cylinder 205h enters the first horizontal groove 205b and makes the toothed plate 204d engage with the gear 204b, the teeth of the toothed plate 204d and the gear 204b are relatively dense, and the outer end of the teeth of the gear 204b is open, thereby avoiding the phenomenon of tooth collision between the toothed plate 204d and the gear 204b, and ensuring the stable work of the whole device.

[0043] In summary, by arranging the reset assembly 205, after the profiled bar moves to the right side of the saw blade 102, i.e. after being cut by the saw blade 102, the profiled bar can be automatically reset, and since the resetting is driven by the third spring 204f, the resetting speed is relatively fast, thereby saving the overall cutting time.

[0044] Embodiment 3, refer to Figures 3-10For the third embodiment of the present application, unlike the previous embodiment, the embodiment provides a feeding control component 300 of the profile lower saw cutting device, solves the problem of how to control the profile feeding speed, and comprises an adjusting assembly 301, an outer plate 301a fixedly connected to the connecting rod 204i, an electric telescopic rod 301b fixedly connected to the outer plate 301a, and a sliding sleeve 301c fixedly connected to the telescopic end of the electric telescopic rod 301b; the replacement component comprises a plurality of sliding strips 302a fixedly connected to the inner side wall of the sliding sleeve 301c, a plurality of sliding grooves 302b matched with the sliding strips 302a provided on the fourth circular ring 203e, and a plurality of gear rings 204g provided on the side wall of the sliding sleeve 301c, wherein the plurality of gear rings 204g are equidistantly fixed to the outer side wall of the sliding sleeve 301c, and the number of teeth on the plurality of gear rings 204g is different.

[0045] Specifically, in this embodiment, unlike the first embodiment, the gear ring 204g is not directly fixed to the fourth circular ring 203e, and the number of teeth on the plurality of gear rings 204g is different, so that the angle of rotation of the gear ring 204g driving the gear 204b to rotate is different, thereby changing the distance of the movement of the toothed plate 204d in one rotation of the gear ring 204g, and controlling the feeding speed.

[0046] In use, first, the feeding speed is determined according to the profile, and then the extension and retraction of the electric telescopic rod 301b is controlled, so that the sliding sleeve 301c moves, thereby enabling different gear rings 204g to cooperate with the gear 204b. The number of teeth on the plurality of gear rings 204g is different, so that the angle of rotation of the gear ring 204g driving the gear 204b to rotate is different. Since the gear 204b is engaged with the toothed plate 204d, the distance of the movement of the toothed plate 204d in one rotation of the gear ring 204g is different, thereby changing the feeding speed. The electric telescopic rod 301b is powered by a battery, so that the phenomenon of wire winding does not occur during use. The electric telescopic rod 301b can be remotely controlled, which is prior art and will not be described here.

[0047] In summary, by providing the feeding control component 300, utilizing the engagement of different gear rings 204g with the gear 204b, and the number of teeth on the gear ring 204g being different, the angle of rotation of the gear ring 204g driving the gear 204b to rotate is changed, thereby changing the speed of the movement of the toothed plate 204d, changing the feeding speed, making the feeding speed reasonable, and making the cutting effect better.
