[0025] 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 in 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.

[0026] The utility model provides Figure 1-3 The winding shaft clamping device shown in the figure includes a winding frame 1, a winding drum 2 is installed on the winding frame 1, and a wire pressing assembly 3 for restraining the external wire of the winding drum 2 is arranged on the winding frame 1. The wire pressing assembly 3 includes a fixed bracket 31, a connecting bracket 32, an extrusion drum 33, a guide shaft 34, an extrusion spring 35 and a locking assembly 36. The fixed bracket 31 is fixedly installed on the top of the winding frame 1, and the extrusion drum 33 is rotatably installed inside the connecting bracket 32. The extrusion drum 33 is located at the top of the winding drum 2, and the guide shaft 34 is fixedly connected to the top of the connecting bracket 32. The extrusion spring 35 is slidably sleeved on the outer wall of the guide shaft 34. The outer wall of the guide shaft 34 is slidably interlaced with the fixed bracket 31, and the extrusion spring 35 is located between the connecting bracket 32 ​​and the fixed bracket 31. Under the action of the guide shaft 34, the connecting bracket 32 ​​can slide up and down relative to the fixed bracket 31. When the winding frame 1 drives the winding drum 2 to rotate the winding wire, the extrusion spring 35 can give an elastic force to the extrusion roller 33 through the connecting bracket 32, so that the extrusion roller 33 squeezes and restrains the wire outside the winding drum 2. The top of the guide shaft 34 is fixedly connected with a connecting plate 37, and a locking assembly 36 is arranged on the fixed bracket 31. The locking assembly 36 is used to lock the guide shaft 34.

[0027] Furthermore, the locking assembly 36 includes a fixed shell 361, a locking block 362 and a locking rod 363. The fixed shell 361 is fixedly connected to the top of the fixed bracket 31. The outer wall of the guide shaft 34 is slidably inserted and sleeved with the fixed shell 361. The end of the locking rod 363 is fixedly connected to the locking block 362. The locking block 362 is slidably arranged inside the fixed shell 361. The outer wall of the guide shaft 34 is provided with a locking hole matching the locking rod 363. When the two guide shafts 34 are driven to rise by the connecting plate 37, the two guide shafts 34 can drive the connecting bracket 32 ​​and the extrusion roller 33 to rise, and the locking rod 363 is engaged with the locking hole outside the guide shaft 34, so that the connecting bracket 32 ​​and the extrusion roller 33 can be locked. The frame 32 drives the extrusion roller 33 to be in a floating state and separated from the winding roller 2, so it is inconvenient to replace the winding roller 2. The interior of the fixed shell 361 is symmetrically fixedly connected with a first fixed plate 366, and one side of the first fixed plate 366 is symmetrically fixedly connected with a first guide rod 367. One end of the first guide rod 367 passes through the locking block 362 and is fixedly connected with a first limit block 368. The outer wall of the first guide rod 367 is slidably sleeved with a first limit spring 365. The first limit spring 365 is located between the first fixed plate 366 and the locking block 362. Under the action of the first limit spring 365, the locking block 362 can drive the locking rod 363 to engage with the locking hole on the outside of the guide shaft 34.

[0028] Furthermore, a connecting rope 364 is fixedly connected to one side of the locking block 362, and a wiring hole matching the connecting rope 364 is opened on one side of the first fixing plate 366. The connecting rope 364 passes through the fixed shell 361 and is fixedly connected to a handle 369. By pulling the handle 369, the locking block 362 can be driven to move away from the guide shaft 34 through the two connecting ropes 364, thereby unlocking the guide shaft 34. The inner wall of the fixed shell 361 is symmetrically fixedly connected with a guide column acting on the connecting rope 364, and the outer wall of the connecting rope 364 is fixedly connected with a second fixing plate 3610. The other side of the first fixing plate 366 is symmetrically fixedly connected with a second guide rod 3611, one end of the second guide rod 3611 passes through the second fixing plate 3610 and is fixedly connected with a second limiting block 3612, and the outer wall of the second guide rod 3611 is slidably sleeved with a second limiting spring 3613, and the second limiting spring 3613 is located between the second fixing plate 3610 and the second limiting block 3612. Figure 3 As shown, the first fixing plate 366 is located between the locking block 362 and the second fixing plate 3610. When the extrusion roller 33 is working, that is, when the locking rod 363 is separated from the locking hole on the outer wall of the guide shaft 34, the connecting rope 364 between the second fixing plate 3610 and the locking block 362 is in a relaxed state, and the connecting rope 364 between the second fixing plate 3610 and the handle 369 is in a taut state, thereby ensuring the stability of the handle 369 on the front side of the fixed shell 361.

[0029] This embodiment provides an enameling machine, which includes the above-mentioned wire take-up shaft clamping device.
