[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] like Figures 1 to 3 As shown, a welding ribbon unwinding mechanism includes a motor 1 and a shaft 2. The shaft 2 includes a shaft body 21. One end of the shaft body 21 is coaxially provided with a shaft edge protrusion 22 for positioning the welding ribbon roll 10. The end of the shaft edge protrusion 22, remote from the shaft body 21, is provided with a connecting portion 23. The connecting portion 23 is coaxially connected to the output end of the motor 1. A connecting member 3 is connected to the outer side of the connecting portion 23. The side of the connecting member 3, remote from the motor 1, is provided with a limit assembly 4 for positioning the welding ribbon roll 10. In addition, a quick-release optical axis lock 5 can be detachably connected to the shaft body 21. The quick-release optical axis lock 5 can cooperate with the limit assembly 4 and the shaft edge protrusion 22 to clamp, position, and secure the welding ribbon roll 10.

[0025] Specifically, in this embodiment, the limiting assembly 4 includes an adjustment block 41, a plug connector 42, an elastic member 43, and a limiting bolt 44. The adjustment block 41 is connected to the connector 3, and one end of the plug connector 42 is axially movable within the adjustment block 41 and connected to the adjustment block 41 via the limiting bolt 44. The elastic member 43 is located within the adjustment block 41 and abuts against one end surface of the plug connector 42. The central axis of the plug connector 42 is parallel to the central axis of the shaft body 21.

[0026] In this embodiment, the elastic member 43 is preferably a spring sleeved on the limiting bolt 44 .

[0027] Furthermore, the installation position of the adjustment block 41 on the connecting member 3 is adjustable along the radial direction of the shaft body 21 to be suitable for welding ribbon rolls 10 of different specifications and models.

[0028] In this embodiment, two groups of adjustment holes 33 are provided on the connecting member 3, and the adjustment holes 33 in each group are arranged at radial intervals along the shaft body 21; two long waist-shaped holes 411 are provided on the adjustment block 41, and one waist-shaped hole 411 corresponds to a group of adjustment holes 31, and is locked by bolts.

[0029] Preferably, the outer diameter of the plug end of the plug connector 42 decreases axially away from the adjustment block 41, and the maximum outer diameter of the plug end of the plug connector 42 is larger than the inner diameter of the positioning hole of the welding ribbon roll 10. During use, the plug end of the plug connector 42 extends into the positioning hole of the welding ribbon roll 10 and is positioned against the welding ribbon roll 10 under the elastic force of the elastic member 43.

[0030] In this embodiment, the connecting member 3 includes a connecting plate portion 31 and a clamping portion 32 provided at one end of the connecting plate portion 31 . The clamping portion 32 is sleeved on the outside of the connecting portion 23 and is locked by a locking screw.

[0031] In this embodiment, a socket is coaxially defined on the end face of the connecting portion 23. A plurality of openings are circumferentially spaced apart on the outer periphery of the connecting portion 23. These openings communicate with the socket and extend through the end face of the connecting portion 23, facilitating plugging and unplugging of the output terminal of the motor 1. The connecting portion 23 is provided with a positioning shoulder for positioning the clamping portion 32, thereby enabling the positioning and installation of the connector 3.

[0032] In this embodiment, the shaft edge protrusion 22 is preferably in the shape of a frustum, and the maximum outer diameter of the shaft edge protrusion 22 is larger than the inner diameter of the center hole of the welding ribbon roll 10. During use, the shaft edge protrusion 22 is snapped into the center hole of the welding ribbon roll 10 placed on the shaft body 21, thereby achieving precise positioning of the welding ribbon roll 10.

[0033] In this embodiment, a positioning portion 51 for positioning the center hole of the welding ribbon roll 10 is provided at one end of the optical axis quick lock 5, so as to position and lock the positioned welding ribbon roll 10.

[0034] The present invention provides a welding ribbon unwinding mechanism. When installing a welding ribbon roll 10, the welding ribbon roll 10 is first placed on the shaft body 1. One end of the welding ribbon roll is accurately positioned using the shaft edge protrusion 22 and the limit assembly 4. Then, the other end of the welding ribbon roll 10 can be positioned and locked using the optical axis quick lock 5 as needed to fix the welding ribbon roll 10 on the shaft 2. When in use, the motor 1 drives the shaft 2 to rotate, driving the welding ribbon roll 10 to rotate synchronously to achieve the unwinding operation.

[0035] Compared with the prior art, the welding tape roll unloading mechanism of the present invention omits components such as a reducer and a coupling, and adopts a direct connection method of the motor 1 to install the shaft 2, which greatly simplifies the installation of the welding tape roll 10, occupies less space, and is more convenient to operate and replace.

[0036] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
