DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0017] As shown in the drawings, the present application discloses an automatic tracking cutting device for stretch net product, which comprises a cutting mechanism and a control system. The cutting mechanism is used for cutting the stretch net, and the control system is used for controlling the cutting mechanism to adjust the cutting position in real time, so as to ensure the cutting quality. Figures 1-4 Specifically, the cutting mechanism comprises a fixed transverse adjustment assembly 10. A longitudinal feed assembly 20 is horizontally slidably arranged on the transverse adjustment assembly 10. A cutting seat 30 is slidably arranged on the longitudinal feed assembly 20. A cutting motor 31 or a cutting tool assembly is arranged on the cutting seat 30. A cutting shaft 32 is connected to the output shaft of the cutting motor 31. Two groups of cutting blades 33 are arranged at intervals on the cutting shaft 32. When arranged, the two groups of cutting blades 33 are slidably arranged on the cutting shaft 32, so that the spacing of the two groups of cutting blades 33 on the cutting shaft 32 is adjustable, thereby controlling the cutting spacing of the two groups of cutting blades 33 and cutting out stretch nets of a specific width.

[0018] The transverse adjustment assembly 10 comprises a fixed groove 11. A transverse screw 12 is rotatably arranged in the fixed groove 11. A transverse motor 14 is arranged at one end of the fixed groove 11. The output shaft of the transverse motor 14 is connected to the transverse screw 12. A transverse nut seat 13 is helically arranged on the transverse screw 12. The transverse nut seat 13 is located in the groove cavity of the fixed groove 11 and has a width consistent with the groove cavity of the fixed groove 11. The transverse motor 14 drives the transverse screw 12 to rotate, thereby driving the transverse nut seat 13 to move along the length direction of the transverse screw 12.

[0019]

[0020] ​The longitudinal feeding assembly 20 is arranged on the transverse nut base 13, and includes a mounting groove 21 fixedly arranged on the transverse nut base 13, and a feeding screw rod 22 rotatably arranged in the mounting groove 21. One end of the mounting groove 21 is provided with a feeding motor 23, and an output shaft of the feeding motor 23 is connected with the feeding screw rod 22. A feeding nut base 24 is spirally arranged on the feeding screw rod 22, and the feeding nut base 24 is located in a groove cavity of the mounting groove 21 and has a width consistent with that of the groove cavity of the mounting groove 21. The feeding motor 23 drives the feeding screw rod 22 to rotate, and drives the feeding nut base 24 to move along the length direction of the feeding screw rod 22.

[0021] The cutting seat 30 is arranged on the feeding nut base 24, and under the action of the transverse adjusting assembly 10 and the longitudinal feeding assembly 20, drives the cutting motor 31 and the cutting blade 33 to move in the transverse direction and the longitudinal direction.

[0022] The cutting seat 30 further upwardly extends a connecting bracket (not shown in the figure), and the connecting bracket is provided with two positioning sensors 40 sliding in the transverse direction. The two positioning sensors 40 are correspondingly arranged above the two groups of cutting blades 33. When the two groups of cutting blades 33 are adjusted in position on the cutting shaft 32, the two positioning sensors 40 are correspondingly and synchronously adjusted, so that the positioning sensors 40 are always corresponded with the cutting blades 33 in position, so as to adapt to the stretching net with different mesh sizes and adapt to different cutting widths. During the cutting process, the positioning sensors 40 are generally arranged at the side of the longitudinal rib of the stretching net, and are used for sensing the position of the longitudinal rib of the stretching net and transmitting to the control system. When the positioning sensors 40 sense that the position of the longitudinal rib of the stretching net changes, the control system controls the transverse adjusting assembly 10 to move to adjust the cutting position of the cutting blade 33.

[0023] Further, the connecting bracket is further provided with a correction sensor 50, and a sensing point of the correction sensor 50 is located at a midpoint of a connecting line of the two positioning sensors 40, and the correction sensor 50 can slide in a direction perpendicular to the connecting line of the two positioning sensors 40, so as to adapt to the stretching net with different mesh sizes. The correction sensor 50 is used for avoiding the state misjudgment of the positioning sensors 40 when encountering the transverse rib. That is, when any one of the positioning sensors 40 or both of the positioning sensors 40 and the correction sensor 50 simultaneously senses, the control system will default to be affected by the transverse rib, and will not consider the signal of the positioning sensor 40 as an exception, so as to avoid the misjudgment. When both of the positioning sensors 40 simultaneously sense and the correction sensor 50 does not sense, the control system will consider that the mesh is too small, and will issue a warning to remind the manual processing.

[0024] The use principle of the automatic tracking cutting device of the stretching net product in the embodiment is as follows: first, the transverse adjusting assembly 10 and the longitudinal feeding assembly 20 are moved to initial positions, then the two positioning sensors 40 are respectively adjusted to the inner side adjacent positions of the longitudinal rib on the two sides of the mesh hole at the cutting position of the stretching net, the correction sensor 50 is adjusted to the middle position of the transverse rib of the mesh hole at the cutting position of the stretching net, and the sensing points of the three sensors form a straight line; then the feeding motor 23 is started to drive the feeding screw 22 to rotate and drive the cutting blade 33 to move to the cutting position, the cutting motor 31 is started, the stretching net moves downward, and the cutting blade 33 cuts the stretching net. During the cutting process, when the longitudinal rib of the stretching net moves to the right, the left positioning sensor 40 senses the position change of the left longitudinal rib and sends the change to the control system in the form of a signal, the control system forms a movement instruction after receiving the signal and sends the movement instruction to the transverse motor 14 to start the transverse motor 14, drives the longitudinal feeding assembly 20 and the cutting blade 33 to move to the right, and compensates for the movement amount of the longitudinal rib of the stretching net to the right; when the longitudinal rib of the stretching net moves to the left, the right positioning sensor 40 senses the position change of the right longitudinal rib and sends the change to the control system in the form of a signal, the control system forms a movement instruction after receiving the signal and sends the movement instruction to the transverse motor 14 to start the transverse motor 14, drives the longitudinal feeding assembly 20 and the cutting blade 33 to move to the left, and compensates for the movement amount of the longitudinal rib of the stretching net to the left, so that the cutting position of the cutting blade 33 on the transverse rib is kept stable, the longitudinal rib is prevented from being damaged, and the quality of the cut product is ensured.
