[0023] When the bellows moves to the bottom of the guide rail 22, the cylinder 52 is started, and the cylinder 52 drives the support rod 31 to move toward the direction close to the bellows through the push plate 53, so that the support rod 31 enters the bellows, provides support for the bellows, and keeps the bellows in a horizontal state.

[0024] Reference Figure 3 and Figure 4 The side of the fixed plate 51 is rotatably mounted with a gear 1 54 and a gear 2 55 meshing with each other, and a motor 2 56 is mounted on the fixed plate 51, and the output end of the motor 2 56 is coaxially fixedly connected with the gear 1 54. The gear 2 55 is sleeved on the outer periphery of the support rod 31, and a synchronization bar 551 is fixed on the inner peripheral surface of the gear 2 55. The outer peripheral surface of the support rod 31 is provided with a synchronization groove 36, and the synchronization bar 551 is slidably matched with the support rod 31 along the length direction of the support rod 31 through the synchronization groove 36.

A circular ring 1 611 is fixed to the side of the channel 1 61 close to the channel 2 62, and a circular ring 2 621 is fixed to the side of the channel 2 62 close to the channel 1 61.

[0027] Reference Figure 6 and Figure 7 , a cylinder 2 7 is fixed between the two cutting lines 1, and a bearing plate 71 is fixed to the top of the piston rod of the cylinder 2 7. A semicircular reversing channel 72 is fixed to the top surface of the bearing plate 71, and two connecting channels 73 are fixed above the reversing channel 72. A circular ring 3 721 is fixed to both ends of the reversing channel 72, and the circular ring 1 611 corresponds to the circular ring 3 721 one by one, and the circular ring 1 611 can be coaxially fitted with the corresponding circular ring 3 721. A circular ring 4 731 and a circular ring 5 732 are fixed to both ends of the connecting channel 73, and the circular ring 4 731 can be coaxially fitted with the adjacent circular ring 1 611, and the circular ring 5 732 can be coaxially fitted with the adjacent circular ring 2 621.

The connecting channel 73 includes four mutually parallel straight rods 733, and the outer circumference of the straight rods 733 can fit the outer circumference of the corrugated tube.

[0029] When the connecting channel 73 is located between channel one 61 and channel two 62, the bellows passes through channel two 62, the connecting channel 73, channel one 61 in sequence and reaches the guide rail 22; when both ends of the bellows need to be cut, the cylinder two 7 is started, and the cylinder two 7 drives the reversing channel 72 to move upward, so that the ring one 611 fits with the corresponding ring three 721, so that the bellows with one end cut can be directly moved to the cutting line 1 on the other side through the reversing channel 72, so that the laser cutting machine body 23 can cut the other end thereof.

[0030] Reference Figure 8 and Fig. 9 The pusher 8 includes a support frame 81 fixed on the bottom surface, and a horizontally arranged top plate 82 is fixed on the support frame 81. A plurality of push boxes 83 with openings arranged downward are installed between the top plate 82 and the moving channel 6. Two connecting rods 84 are hinged between the top surface of the push box 83 and the top plate 82, and the two connecting rods 84 are arranged parallel to each other. A cylinder 52 is hinged on the bottom surface of the top plate 82, and the end of the piston rod of the cylinder 52 is hinged to the side of one of the connecting rods 84. Two rollers 86 are rotatably installed in the push box 83, and a motor 3 87 is installed in the push box 83, and the output end of the motor 3 87 is coaxially fixedly connected to one of the rollers 86. The outer periphery of the two rollers 86 is provided with a belt 88, and the outer side surface of the belt 88 is provided with a belt tooth 89 that can mesh with the corrugation of the outer peripheral surface of the corrugated tube.

[0031] Place the bellows between the four horizontal rods 64, and then start cylinder three 85. Cylinder three 85 drives the connecting rod 84 to rotate, and then drives the push box 83 to move downward, so that the belt 88 abuts against the top of the bellows, and the belt teeth 89 on the belt 88 mesh with the corrugations on the outer peripheral surface of the bellows, and then start motor three 87. Motor three 87 drives the belt 88 to rotate through roller 86, thereby pushing the bellows to move in the horizontal direction.

[0033] After the laser cutting machine body 23 cuts the corrugated tube, the support rod 31 detaches from the corrugated tube, and the cut part moves downward to the horizontal plate 1 911 through the inclined plate 912 under the action of its own gravity. The corrugated tube after cutting continues to move toward the direction close to the support rod 31, and bends upward under the abutment of the inclined plate 912 and enters between the horizontal plate 2 913 and the connecting rod 2 1212, and then enters the channel 3 121, so as to output the corrugated tube after cutting.

[0034] The implementation principle of a double-station laser cutting machine for cutting corrugated tubes in an embodiment of the present application is as follows: a first corrugated tube is conveyed to the position of a laser cutting machine body 23 through one of the feeding assemblies 11, and then the support rod 31 is extended into the corrugated tube, and the pushing assembly 5 is used to make the support plate 34 tightly abut against the inner wall of the corrugated tube, so that the support rod 31 and the corrugated tube remain relatively fixed, and the support rod 31 is driven to rotate by the rotating assembly 4, and the support rod 31 drives the corrugated tube to rotate synchronously, so that the laser cutting machine body 23 can cut the corrugated tube. When cutting the first corrugated tube, another set of feeding assemblies 11 conveys the second corrugated tube to the guide rail 22. After the laser cutting machine body 23 completes cutting of the first corrugated tube, it moves to the position of the second corrugated tube through the guide rail 22 and cuts it, thereby realizing double-station cutting with high cutting efficiency.

[0035] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
