[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the present invention, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0025] The following is a detailed description of the implementation of the present invention in conjunction with the specific drawings:

[0026] Figure 1 A first structural schematic diagram of a diaphragm reverse installation device provided by an embodiment of the utility model is shown in FIG. Figure 2 for Figure 1 A second structural schematic diagram of a diaphragm reverse installation device provided by an embodiment of the utility model is shown as follows: Figure 1 and Figure 2 As shown, a diaphragm reverse installation device includes a transmission component 1, a feeding component 2, a bracket 3, a fixing block 4 and a servo motor 5. The transmission component 1 includes three sets of transmission wheels 11 and a transmission belt 12. The feeding component 2 includes a loading roller 21, a feeding roller 22, a guide shaft 23 and a diaphragm sleeve 24. The transmission component 1 and the feeding component 2 are both detachably connected to the bracket 3.

[0027] The bracket 3 is provided with a fixing block 4 which is detachably connected to the bracket 3, the servo motor 5 is detachably connected to the fixing block 4, a cavity is provided on the side of the fixing block 4 close to the bracket 3, three groups of transmission wheels 11 and a transmission belt 12 are accommodated in the cavity, the motor shaft of the servo motor 5 passes through an opening on the fixing block 4 and is connected to a group of transmission wheels 11, the fixing block 4 includes two groups of symmetrical side walls, two groups of bolt structures are respectively arranged on each group of side walls, the fixing block 4 is detachably connected to the bracket 3 by bolts, so as to facilitate the rapid installation of the diaphragm reverse mounting device.

[0028] Each set of transmission wheels 11 is connected by a transmission belt 12, and the servo motor 5 drives the transmission wheels 11 to rotate. The three sets of transmission wheels 11 form a stable triangle, and all the transmission wheels 11 rotate synchronously in the same direction, wherein the servo motor 5 can adjust the speed and direction of rotation as needed.

[0029] The loading roller 21 and the feeding roller 22 are respectively fixedly connected to a group of transmission wheels 11. When the transmission wheel 11 rotates, the loading roller 21 and the feeding roller 22 are driven to rotate clockwise in the same direction. If the diaphragm is installed correctly, the diaphragm is transported to the buffer area. If the diaphragm is reversed and cannot be discharged, the loading roller 21 stops rotating, driving the transmission wheel 11 and the servo motor 5 to stop rotating. When the servo motor 5 stops rotating, an alarm signal is sent to the system to remind the winding device that the diaphragm is reversed.

[0030] The diaphragm reverse loading device includes a loading roller 21 and a feeding roller 22, and a guide shaft 23 is provided on the side close to the feeding roller 22. The guide shaft 23 is rotatably connected to the bracket 3. The guide shaft 23 and the feeding roller 22 tighten the diaphragm, wherein the feeding roller 22 provides rotational power, and the guide shaft 23 is an unpowered rotating shaft, which cooperates with the feeding roller 22 to transport the diaphragm to the buffer area of ​​the winder.

[0031] A diaphragm sleeve 24 is provided on the loading roller 21, on which a wound diaphragm is mounted. The diaphragm sleeve 24 is detachably connected to the loading roller 21. When the loading roller 21 rotates clockwise, the diaphragm is discharged in a clockwise direction. At this time, the installation position of the sleeve is correct. When the diaphragm sleeve 24 is reversely installed, the material cannot be discharged, causing the loading roller 21 to stop rotating.

[0032] The diaphragm reverse installation device includes three groups of transmission wheels 11, including a driving wheel and a driven wheel. The driving wheel is movably connected to the motor shaft of the servo motor 5. The loading roller shaft 21 and the feeding roller shaft 22 are respectively connected to a group of driven wheels. The driving wheel and the driven wheel are connected through a transmission belt 12. When the diaphragm device is working normally, the driving wheel drives the driven wheel to rotate. When the diaphragm sleeve 24 is reversed, the driven wheel stops rotating, and the conveyor belt 16 and the driving wheel stop rotating due to friction resistance. The servo motor 4 detects that the resistance encountered when the motor shaft rotates increases, and sends an alarm signal to remind the diaphragm sleeve 24 to be reversed.

[0033] The membrane reverse installation device further includes a bracket 3, which is a partition in this embodiment, and a loading roller 21, a feeding roller 22 and a guide shaft 23 are arranged on a side away from the servo motor 5, and a transmission wheel 11 and a transmission belt 12 are arranged on a side close to the servo motor 5. The servo motor 5 and the membrane feeding device are arranged on different sides, which can effectively prevent the membrane from being rolled into the servo motor 5.

[0034] The bracket 3 is also provided with two groups of mounting holes, through which the loading roller shaft 21 and the feeding roller shaft 22 are fixedly connected to the driving wheel 11 , and the loading roller shaft 11 and the feeding roller shaft 22 rotate synchronously with the driving wheel 11 .

[0035] The transmission wheel 11 is a pulley or a gear, and the transmission belt 12 is a belt or a chain. This structure can ensure that the transmission device does not slide. When the driven wheel stops rotating, the friction resistance to the driving wheel rotation process is increased, so that the servo motor 4 stops rotating due to the resistance. Compared with the direction and speed roller, the servo motor can provide greater force, and can adjust the position according to the actual width of the diaphragm, change the gap size, and has higher applicability.
