As shown in fig. 1-8, when the apparatus of the present invention is in the initial state, the output shaft 25 is located on the upper side of the driving wheel disk shaft 30, the upper end surface of the cutter limiting slider 38 abuts against the upper end wall of the cutter limiting cavity 39, the trigger rod 41 is located in the cutting trigger cavity 42, the rotating rod return spring 44 and the cutter trigger spring 36 are in the natural state, and the cutter output spring 34 is in the compressed state.
Sequence of mechanical actions of the whole device: when the PVC pipe works, one end of a PVC pipe penetrates through the feeding cavity 12 to a certain length in the working cavity 11, so that the transmission friction wheel 20, the driven friction wheel 13 and the pipe limiting wheel 27 are abutted against the outer wall of the PVC pipe, the motor 23 is started, the motor 23 runs to drive the transmission shaft 19 to rotate clockwise, the transmission shaft 19 rotates to drive the fixed shaft sleeve 47 and the threaded rod 16 to rotate, the threaded rod 16 rotates to drive the angle adjusting rod 60 to rotate, the auxiliary angle adjusting rod 59 drives the slide block transmission shaft 58 to rotate synchronously, the slide block transmission shaft 58 is influenced by the limiting effect of the hinge shaft 56, the slide block transmission shaft 58 rotates to drive the slide block transmission rod 57 to move upwards and swing leftwards simultaneously, and further drives the hinge shaft 56 to move upwards, the hinge shaft 56 moves to drive the slide block connecting rod 55 to move upwards and further drive the slide block, the limiting shaft 53 rotates clockwise to drive the transmission wheel disc 29 to rotate in the same direction so as to drive the output shaft connecting plate 50 to rotate clockwise, the output shaft connecting plate 50 rotates to drive the output shaft 25 to rotate so as to drive the bent pipe sliding rail wheel 26 to rotate in the same direction until the bent pipe sliding rail wheel 26 abuts against the outer wall of the PVC pipe, meanwhile, the transmission shaft 19 rotates to drive the half gear 18 to rotate clockwise, and in the process, the half gear 18 is not meshed with the driven straight gear 22; when the return bend slide rail wheel 26 lasts clockwise shifting, receive the spacing effect influence of the spacing wheel 27 of tubular product, the one end that PVC and return bend slide rail wheel 26 offset is extruded by return bend slide rail wheel 26 and is bent around the spacing wheel 27 outer wall of downside tubular product, owing to receive the spacing round 27 outer wall restriction effect influence of tubular product, PVC bends the department deformation and is restricted by the spacing wheel 27 outer wall of tubular product and makes it can only do standard deformation in the circular passageway that two spacing wheels 27 outer walls of tubular product are constituteed, and be unlikely to excessive deformation or cause phenomenons such as tearing by excessive deformation.
When the sliding block transmission shaft 58 rotates to the position right above the fixed shaft sleeve 47, the bending work of the PVC pipe is already done, and since it continues to rotate, the sliding block transmission shaft 58 starts to drive the sliding block transmission rod 57 to move downwards and swing right at the same time, further drives the sliding block 54 to slide downwards along the sliding rod 48, and finally drives the elbow sliding rail wheel 26 to make counterclockwise return motion, at this time, the transmission shaft 19 rotates to drive the half gear 18 to rotate until the half gear 18 is meshed with the driven spur gear 22, the half gear 18 rotates to drive the driven spur gear 22 to rotate counterclockwise, further drives the transmission friction wheel 20 to rotate counterclockwise through the transmission friction wheel shaft 21, influenced by the friction effect of the driven friction wheel 13 and the transmission friction wheel 20 on the PVC pipe, the transmission friction wheel 20 rotates counterclockwise to drive the PVC pipe to move forward, when the right end of the PVC pipe abuts against the rotating rod 45, influenced by the thrust effect of the PVC pipe, the rotating rod return spring 44 is compressed downwards under the influence of the pressure of the rotating rod 45, the rotating rod 45 swings to drive the trigger rod 41 to rotate anticlockwise so as to further pull the cutter trigger pull rope 37, the cutter trigger pull rope 37 pulls to influence, the cutter limiting slide block 38 slides rightwards to separate from the cutter limiting cavity 39, the cutting knife 40 moves downwards rapidly under the action of the downward elasticity of the cutter output spring 34 and cuts off the bent PVC pipe, and the cut PVC bent pipe falls to the outside through the discharging cavity 15.
When the PVC elbow is cut off, the half gear 18 is disengaged from the driven straight gear 22 again, meanwhile, the elbow sliding rail wheel 26 rotates clockwise again and bends the PVC pipe, the rotating rod 45 is reset in the clockwise direction under the influence of the upward thrust of the rotating rod reset spring 44, the cutter limiting slide block 38 moves leftwards under the influence of the leftward thrust of the cutter trigger spring 36 to abut against the right end face of the cutter 40, the output shaft 25 drives the cutter reset pull rope 49 in the clockwise rotation process of the elbow sliding rail wheel 26, the cutter 40 is driven to move upwards until the cutter limiting cavity 39 is matched and fixed with the cutter limiting slide block 38, so that the reset operation of the cutter 40 is realized, and the reciprocating motion realizes the continuous operation of bending the PVC pipe and cutting off the bent PVC elbow part; when the bending angle of the PVC pipe needs to be adjusted, the device is stopped, the positioning nut 17 is controlled to point to the angle adjusting cavity 46, the distance between the transmission shaft 19 and the sliding block transmission shaft 58 is adjusted by rotating the positioning nut 17, so that the up-and-down reciprocating stroke of the sliding block 54 is changed, and finally, the stroke length of the circular reciprocating motion of the bent pipe sliding rail wheel 26 is changed, and the controllable bending angle of the PVC pipe is realized.
The invention has the beneficial effects that: the restriction through the circular outer wall of the spacing round of tubular product can prevent that the PVC pipe from excessively warping at the in-process of buckling, can adjust the PVC pipe angle of buckling as required through rotatory positioning nut, cooperation through between semi-gear and the output shaft can make the PVC pipe carry out in turn in the work of conveying with bending, cooperation through between return bend slide rail wheel and the cutting knife can make the PVC pipe carry out in turn in the work of buckling with cutting off, with this realization application current PVC tubular product carries out the work of making the PVC elbow fitting of special demand many times and fast.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
