[0021] Please refer to Figs. 1-2 , Figs. 1-2This utility model discloses a wire marking machine conveying module, comprising a base plate 1, a conveying assembly 2, and a drive unit 3. The conveying assembly 2 includes a conveying roller 21, a switching end 22, and a floating roller 23. One end of the conveying roller 21 is rotatably connected to the base plate 1. The switching end 22 is disposed on the base plate 1. One end of the floating roller 23 is connected to the switching end 22 and can rotate relative to the switching end 22. A pushing gap is formed between the conveying roller 21 and the floating roller 23. One end of the conveying roller 21 is provided with a driving gear 211, and one end of the floating roller 23 is provided with a driven gear 231. The switching end 22 is used to drive the floating roller 23 to a first position or a second position. When the floating roller 23 is in the first position, the floating roller 23 and the conveyor roller 21 are used to clamp the wire tube in the advance gap, and the driving gear 211 and the driven gear 231 are engaged. When the floating roller 23 is in the second position, the floating roller 23 and the conveyor roller 21 are separated, and the driving gear 211 and the driven gear 231 are disengaged. The driving unit 3 is connected to the conveyor roller 21 for transmission, and the driving unit 3 is used to drive the conveyor roller 21 to rotate around its own axis.

[0022] It should be noted that when the floating roller 23 is in the second position, the driving gear 211 and the driven gear 231 are separated, and the pushing gap between the conveying roller 21 and the floating roller 23 is relatively large, which makes it convenient to pass the wire tube through the pushing gap; when the floating roller 23 is in the first position, the driving gear 211 and the driven gear 231 are engaged, and the pushing gap between the conveying roller 21 and the floating roller 23 is relatively small. The rotation of the conveying roller 21 can drive the floating roller 23 to rotate synchronously, so as to realize the forward conveying of the wire tube.

[0023] It should be noted that the floating roller 23 is movable between the first position and the second position, wherein the axis of the floating roller 23 is parallel to the axis of the conveying roller 21, and when the floating roller 23 is in the first position, the distance between the floating roller 23 and the conveying roller 21 is less than or equal to 1 mm.

[0024] Based on the above scheme, in order to improve the friction between the conveying roller 21 and the floating roller 23, specifically, the surfaces of the floating roller 23 and the conveying roller 21 are rubber layers. In addition, anti-slip textures are provided on the rubber layers, which can further reduce the friction between the floating roller 23 and the conveying roller 21 on the wire tube and make the anti-slip ability stronger.

[0025] In this specific embodiment, a position holding mechanism 4 is also included. The position holding mechanism 4 is connected between the base plate 1 and the switching end 22. The position holding mechanism 4 is used to keep the floating roller 23 between the movement paths of the first position and the second position, and normally drives the floating roller 23 to move towards the conveying roller.

[0026] It should be noted that the position holding mechanism 4 is not limited to a specific structure. As long as it can be linked with the cover, when the cover is open, the position holding mechanism 4 drives the switching end 22 to move so that the floating roller 23 is in the second position, and when the cover is closed, the position holding mechanism 4 drives the switching end 22 to move so that the floating roller 23 is in the first position. No other limitations are made here.

[0027] In this specific embodiment, the position holding mechanism 4 includes a transmission member 41 and two elastic members 42. The transmission member 41 is rotatably connected to the base plate 1 and is linked to the cover. One elastic member 42 is connected between the transmission member 41 and the switching end 22, and the other elastic member 42 is connected between the switching end 22 and the base plate 1. Both elastic members are return springs.

[0028] It should be noted that the switching end is not limited to a specific structure. In this specific embodiment, the switching end 22 includes a support plate 221 and a pin 222. The pin 222 is fixedly connected to the base plate 1, the support plate 221 is rotatably connected to the pin 222, the floating roller 23 is rotatably connected to the support plate 221, one elastic element 42 is connected between the transmission element 41 and the support plate 221, and another elastic element 42 is connected between the support plate 221 and the base plate 1.

[0029] Specifically, when the transmission component 41 includes a rotating shaft 411, a mounting block 412, and a protrusion 413, the rotating shaft 411 is rotatably connected to the base plate 1, the mounting block 412 and the protrusion 413 are both fixedly connected to the rotating shaft 411, an elastic element 42 is connected between the mounting block 412 and the support plate 221, and the protrusion 413 is linkedly connected to the cover.

[0030] In actual use, a cover is hinged to the base plate 1, and a pusher is provided on the cover. When the cover is closed, under the action of an elastic element, the floating roller 23 is in the first position, the driving gear 211 and the driven gear 231 mesh, and the wire tube is clamped in the pushing gap between the floating roller 23 and the conveying roller 21. When the cover is opened, the pusher abuts against the protrusion 413, thereby pushing the rotating shaft 411 to rotate. At this time, another elastic element can pull the support plate 221 to rotate around the pin shaft 222, so that the driving gear 211 and the driven gear 231 are separated, and the width of the pushing gap between the floating roller 23 and the conveying roller 21 becomes larger, making it convenient for the operator to pass the wire tube through the pushing gap.

[0031] Based on the above scheme, in order to limit the rotation angle of the support plate 221 around the pin 222 and improve the stability of the support plate during rotation, specifically, the support plate 221 is provided with a guide hole 221a, and the base plate 1 is fixed with a slide rod 11. The slide rod 11 is slidably engaged with the guide hole 221a. When the support plate 221 rotates around the pin 222 and the slide rod 11 is located at one end of the guide hole 221a, the floating roller 23 is in a first position. When the slide rod 11 is located at the other end of the guide hole 221a, the floating roller 23 is in a second position.

[0032] In this specific embodiment, the drive unit 3 includes a reduction motor 311, a first gear 312, and a second gear 313. The reduction motor 311 is fixedly connected to the base plate 1, and the output end of the reduction motor 311 is fixedly connected to the first gear 312. The second gear 313 is fixedly disposed at one end of the conveyor roller 21, and the first gear 312 and the second gear 313 mesh with each other. It should be noted that a gear transmission unit is also included, which includes at least one third transmission gear 5. The third transmission gear 5 is rotatably disposed on the base plate 1 and is disposed between the first gear 312 and the second gear 313. The third transmission gear 5 meshes with the first gear 312 and the second gear 313. It should be noted that by setting the third transmission gear 5, the gear ratio can be changed, and the rotational speed of the second gear 313 relative to the first gear 312 can be adjusted.

[0033] To better understand this utility model, the following is combined with... Figs. 1-2 The technical solution of this utility model is described in detail below:

[0034] When the cover is open, the floating roller 23 is in the second position, the driving gear 211 and the driven gear 231 are separated, and the pushing gap between the floating roller 23 and the conveying roller 21 is large, which makes it convenient to pass the wire tube through the pushing gap. When the cover is closed, the transmission component 41 can drive the switching end 22 to put the floating roller 23 in the first position, and the driving gear 211 and the driven gear 231 mesh, so that the wire tube can be clamped in the pushing gap. The driving part 3 drives the conveying roller 21 to rotate, thereby driving the floating roller 23 to rotate synchronously, realizing the dual-power conveying of the wire tube.
