DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0021] See also Figures 1-4 The figure shows an automatic threading machine for blinds, comprising a machine console 101, a workbench 102 provided on one side of the machine console 101, a first threading station 104 and a plurality of second threading stations 105 connected to the workbench 102 via a slide rail 103, the first threading station 104 being disposed near the machine console 101, and an adjustment assembly provided on the workbench 102 for adjusting each of the second threading stations 105;

[0022] The adjustment assembly includes two fixed plates 201 fixedly connected to the side of the workbench 102 away from the operating button of the machine body console 101, a threaded rod 202 is rotatably connected between the two fixed plates 201, and a plurality of threaded sleeves 203 are threadedly connected to the side walls of the threaded rod 202. A first L-shaped plate 204 is fixedly connected to the side of the second belt threading station 105 close to the threaded rod 202, and the side of the first L-shaped plate 204 away from the second belt threading station 105 is connected to the threaded sleeve 203 via a connecting assembly. The first L-shaped plate 204 is provided with a driving assembly for driving the threaded sleeve 203;

[0023] It should be noted here that: through the setting of the adjustment component, under the action of the driving component, while realizing the position adjustment of the second threading station 105, the accuracy of the adjustment of the second threading station 105 is improved, and the self-locking property between the threaded sleeve 203 and the threaded rod 202, after the adjustment of the second threading station 105 is completed, the second threading station 105 is automatically locked, and there is no need to manually limit the second threading station 105, thereby reducing the cumbersomeness of the adjustment operation and further improving the efficiency of the adjustment of the threading station.

[0024] It should be emphasized that the self-locking condition of the threaded sleeve 203 and the threaded rod 202 mainly depends on the relationship between the thread lead angle and the equivalent friction angle. Specifically, the thread lead angle needs to be smaller than the equivalent friction angle. This is because when the thread lead angle is smaller than the equivalent friction angle, the friction torque between the threads is large enough to resist the loosening torque caused by vibration or impact, thereby maintaining the tight state of the threaded connection and achieving self-locking.

[0025] It is worth noting that the automatic blade threading machine for Venetian blinds is only briefly drawn here. For the specific mechanism, please refer to the authorization announcement number CN220782874U, a processing equipment for Venetian blinds blades.

[0026] See also Figure 3 and Figure 4 The connecting assembly shown in the figure includes an annular connecting groove 301 formed on the side wall of the threaded sleeve 203, an annular ring 302 is rotatably connected to the annular connecting groove 301, and the side of the first L-shaped plate 204 away from the second threading station 105 is connected to the annular ring 302;

[0027] It should be noted here that: by setting the connection assembly, the first L-shaped plate 204 and the threaded sleeve 203 are rotationally connected.

[0028] See also Figure 1 The workbench 102 shown in the figure has a plurality of scale lines (not shown in the figure) on one side close to the first L-shaped plate 204, and an indicator plate (not shown in the figure) is fixedly connected to the side of the first L-shaped plate 204 close to the scale lines;

[0029] It should be noted here that the setting of the scale lines provides precise guidance for the adjustment of the second threading station 105, thereby achieving position adjustment of the second threading station 105 while improving the accuracy of adjustment of the second threading station.

[0030] Working principle: When threading the blades of the Venetian blinds, first the cut blades are fed into the threading device. The traction mechanism of the threading device tightens the ladder rope and makes its weft parallel to the incision, preparing for the insertion of the blades. Then the lifting mechanism is used to lift the aluminum blinds blades from the lower supporting plane to the upper supporting plane, while ensuring that the blades are accurately inserted into the sections of the ladder rope, thereby achieving the threading of the blades. It should be noted that the threading of the blades of the Venetian blinds by the automatic threading machine is only briefly described here. The specific operation method and working principle are existing technologies and will not be elaborated on in detail.

[0031] When threading the blades of different types of Venetian blinds, it is necessary to adjust the position of each second threading station 105 according to the length of the blade and the perforation position. When adjusting the position of each second threading station 105, the driving component is first used to drive the threaded sleeve 203 to rotate. Under the threaded engagement transmission action of the threaded sleeve 203 and the threaded rod 202, the first L-shaped plate 204 is driven to move, thereby further driving the second threading station 105 to move, and under the reference action of the scale line, the second threading station 105 is moved. The adjustment of the belting station 105 provides precise guidance, thereby improving the accuracy of the adjustment of the second belting station 105 while achieving the position adjustment of the second belting station 105, and the self-locking property between the threaded sleeve 203 and the threaded rod 202 enables the second belting station 105 to be automatically locked after the adjustment is completed, without the need to manually limit the second belting station 105, thereby reducing the tediousness of the adjustment operation and further improving the efficiency of the adjustment of the belting station.

The driving assembly shown in the figure includes a second L-shaped plate 401 fixedly connected to one side of the first L-shaped plate 204. The second L-shaped plate 401 is rotatably connected to a driving rod 402. The driving rod 402 is located between the first L-shaped plate 204 and the second L-shaped plate 401. A gear 403 is fixedly connected to the side wall of the driving rod 402. A gear ring 404 is fixedly connected to the side wall of the threaded sleeve 203. The gear ring 404 and the gear 403 are meshed with each other.

[0033] It should be noted here that: through the setting of the drive component, when the rotating ball 405 rotates, the gear 403 on the drive rod 402 will be driven to rotate. When the gear 403 rotates, the threaded sleeve 203 is driven to rotate under the threaded engagement transmission action of the gear 403 and the ring gear 404.

[0034] See also Figure 3 and Figure 4 , the end of the driving rod 402 away from the first L-shaped plate 204 is fixedly connected to the rotating ball 405;
