[0030] Moreover, the guide opening system in the present application has the following guide opening tool automatic switching device. Preferably, as shown in Figure 1 and Figure 2 The guide opening system has two guide opening tool automatic switching devices, and the two guide opening tool automatic switching devices are symmetrically arranged.

[0031] As shown in Figures 1 to 4 The guide opening tool automatic switching device in the present application includes a mounting frame 20, a switching swing arm 30, a driving assembly 40 and a clamping assembly 50. The mounting frame 20 has a cord winding position 21 and a cushion winding position 22; the switching swing arm 30 is rotatably arranged on the mounting frame 20; the driving assembly 40 is arranged on the mounting frame 20, and the driving assembly 40 is drivingly connected with the switching swing arm 30, so that the switching swing arm 30 can swing between the cord winding position 21 and the cushion winding position 22; the clamping assembly 50 is arranged on the switching swing arm 30, and at least a part of the clamping assembly 50 can move along the switching swing arm 30 and form a clamping space with one end of the switching swing arm 30.

[0032] When the automatic switching device for the lead-out tooling in the present application is used, since the driving assembly 40 and the switching swing arm 30 are driven and connected, when the lead-out tooling 10 needs to be moved from the cord fabric winding position 21 to the cushion fabric winding position 22, the switching swing arm 30 can be swung by the driving assembly 40, and the switching swing arm 30 can be moved to the position corresponding to the cord fabric winding position 21. After the switching swing arm 30 moves and hits the position corresponding to the cord fabric winding position 21, the clamping space size can be adjusted by the movement of the clamping assembly 50 relative to the switching swing arm 30, so that the lead-out tooling 10 of the cord fabric winding position 21 can be clamped.

Therefore, compared with the prior art, the automatic switching device for the lead-out tooling in the present application can automatically switch the position of the lead-out tooling 10, thereby replacing the manual operation mode. Therefore, the automatic switching device for the lead-out tooling in the present application effectively solves the problems of low switching efficiency and certain danger in the prior art.

[0033] Moreover, when the two automatic switching devices for the lead-out tooling are symmetrically arranged, the specific size of the mounting frame 20 can be adaptively adjusted, so that the two automatic switching devices for the lead-out tooling can share one mounting frame 20.

[0034] Optionally, the switching swing arm 30 is at least two, and the two switching swing arms 30 are arranged at the two ends of the cord fabric winding position 21 and the cushion fabric winding position 22 respectively, and the number of the switching swing arms 30 is equal to and corresponds to the number of the driving assembly 40 and the clamping assembly 50. Therefore, in the present application, when the number of the switching swing arms 30 is more than one, all the switching swing arms 30 can move synchronously, so as to ensure that the switching swing arms 30 can more stably drive the lead-out tooling 10 to switch the position. Moreover, in one specific embodiment of the present application, the corresponding switching swing arm 30, driving assembly 40 and clamping assembly 50 are two groups, and the two groups of switching swing arms 30, driving assemblies 40 and clamping assemblies 50 are symmetrically arranged on the mounting frame.

[0035] It should be noted that in the present application, the cord winding station 21 and the cushion winding station 22 are respectively used for placing the guide opening tool 10, the guide opening tool 10 generally has a cylindrical structure, and the two ends of the axis of the cylindrical structure respectively extend out of the mounting shafts, at this time, the two mounting shafts can be matched with the two ends of the cord winding station 21 and the two ends of the cushion winding station 22 respectively, so that the guide opening tool 10 can be placed on the cord winding station 21 or the cushion winding station 22. And in the present application, when the switching swing arm 30 is two, the two switching swing arms 30 are actually corresponding to the two mounting shafts extending out of the two ends of the cylindrical structure, and can realize clamping and loosening of the mounting shaft by cooperating with the clamping assembly 50.

[0036] Therefore, in the present application, the two ends of the cord winding station 21 and the two ends of the cushion winding station 22 are one-to-one corresponding, and one set of one-to-one corresponding end of the cord winding station 21 and end of the cushion winding station 22 is located in the movement path of one of the switching swing arms 30, and the other set of one-to-one corresponding end of the cord winding station 21 and end of the cushion winding station 22 is located in the movement path of the other switching swing arm 30, so as to realize the switching of the guide opening tool 10 between the cord winding station 21 and the cushion winding station 22. And in the present application, the guide opening revolution automatic switching device generally transports the guide opening tool 10 from the cord winding station 21 to the cushion winding station 22. And in a specific embodiment of the present application, in the height direction of the mounting frame 20, the cord winding station 21 is located above the cushion winding station 22. And in the horizontal direction, the cord winding station 21 and the cushion winding station 22 have a certain distance.
