Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coil cutting equipment, in particular to an automatic coil cutting machine coil fixing component and an automatic coil cutting machine Background Art
[0002] The automatic roll cutter is an automated device used for precision slitting of products such as adhesive tapes, protective films and paper. It can cut conventional long roll materials into short roll materials of specified width. When cutting long roll materials, the current automatic roll cutter requires the operator to first sleeve the conventional long roll materials on the rotating mandrel of the automatic roll cutter, and then the cutter of the automatic cutting table moves equidistantly along the axial direction to cut the long roll materials. Since the long roll materials are directly sleeved on the rotating mandrel, and the inner cylinder sizes of long roll materials of different specifications and models may be different, during the rotation of the rotating mandrel, when there is a large gap between the inner cylinder and the rotating mandrel, the long roll materials will shake and move during the processing, thereby affecting the slitting accuracy and quality of the long roll materials by the cutter.

[0007] In the above technical solution, an annular positioning groove matching the elastic ring is provided on the outer wall of the coupling cylinder; and a connecting groove matching the elastic ring is provided on the outer side of the rear end of the clamping jaw.
[0008] In the above technical solution, a piston pull rod is fixedly connected to the piston.

[0018] The coil fixing assembly of the automatic coil cutting machine provided by the utility model can be applied to the automatic coil cutting machine, and the coil fixing assembly includes a mating cylinder 1 and a clamping member 2; one end of the rotating core shaft 4 of the automatic coil cutting machine is a docking end, which is docked with the mating cylinder 1, and the other end is a movable supporting end, which is connected to the tail swing assembly 3 on the automatic coil cutting machine. When one end of the rotating core shaft 4 is docked with the mating cylinder 1, the tail swing assembly 3 can support the other end of the rotating core shaft 4, and can also release the support of the rotating core shaft 4. The tail swing assembly 3 in this embodiment is the same as the structure of the existing automatic coil cutting machine, so it is not described in detail; after the operator puts the conventional long coil material on the rotating core shaft 4, the long coil material can be fixed by the clamping member 2 to avoid shaking and movement during the processing.
[0019] like Figures 1 to 4 As shown, in one embodiment of the utility model, the coil fixing assembly of the automatic coil cutting machine includes a matching cylinder 1 and a clamping member 2.
[0020] The matching cylinder 1 is connected to the rotating drive assembly of the automatic rolling machine. The matching cylinder 1 is in the shape of a circular groove and its open end is for docking with the rotating core shaft 4 of the automatic rolling machine. The rotating drive assembly is used to drive the matching cylinder 1 and the rotating core shaft 4 to rotate. The rotating drive assembly in this embodiment has the same structure as the existing automatic rolling machine, so it will not be described in detail.
[0021] The clamping member 2 includes a piston 21, an elastic ring 22 and a plurality of jaws 23; the piston 21 is arranged in the inner cavity of the mating cylinder 1, and an annular groove 211 is arranged on the side wall of the piston 21; a plurality of jaws 23 are arranged at intervals along the circumference of the mating cylinder 1 on the side wall of the opening end of the mating cylinder 1, the middle part of the jaw 23 is rotatably connected to the side wall of the mating cylinder 1, an inclined surface 231 is arranged at the front end of the jaw 23, a clamping bayonet 232 for fixing the coil is arranged between the front end and the middle part of the jaw 23, a roller 233 is rotatably connected to the inner side of the rear end of the jaw 23, the roller 233 extends into the inner cavity of the mating cylinder 1 and is arranged in the annular groove 211; the elastic ring 22 is sleeved on the outer wall of the mating cylinder 1 and fixedly connected to the outer side of the rear end of the jaw 23.
[0022] Specifically, a rotating support shaft 5 fixedly connected to the side wall of the matching cylinder 1 is provided in the middle of the clamping jaw 23, and the rotating support shaft 5 is perpendicular to the axis of the matching cylinder 1; a roller rotating shaft 6 is rotatably connected to the inner side of the rear end of the clamping jaw 23, and the roller rotating shaft 6 is perpendicular to the axis of the matching cylinder 1. An annular positioning groove 7 matching the elastic ring 22 is provided on the outer wall of the matching cylinder 1; a connecting groove 8 matching the elastic ring 22 is provided on the outer side of the rear end of the clamping jaw 23.
[0023] When the coil fixing assembly of the automatic coil cutting machine is used, a conventional long roll material is sleeved on the rotating core shaft 4. Since the front end of the clamping jaw 23 is provided with an inclined surface 231, the long roll material is pushed toward the clamping member 2, so that the long roll material can be easily pushed to the clamping bayonet 232 of the clamping jaw 23; when the long roll material approaches the clamping jaw 23, since the roller 233 is arranged in the annular groove 211 and the middle part of the clamping jaw 23 is provided with a rotating support shaft 5, the clamping jaw 23 can rotate around the rotating support shaft 5, firstly, the outer wall of the long roll material presses the inclined surface 231 of the front end of the clamping jaw 23, and the front end of the clamping jaw 23 is away from the matching cylinder 1 The rear end of the clamp 23 rotates outward, and the piston 21 rotates inward. The piston 21 is used to block the roller 233, which can limit the inward rotation angle of the roller 233. Since the elastic ring 22 is fixedly connected to the outer side of the rear end of the clamp 23, when the rear end of the clamp 23 rotates inward, it pulls the elastic ring 22 inward. However, due to the elastic force of the elastic ring 22, the clamping force of the clamp 23 on the long roll material can always be maintained. When the end of the long roll material enters the clamping bayonet 232, the long roll material can be positioned and clamped to avoid shaking and movement of the long roll material during processing.
[0024] Preferably, a piston pull rod 212 is provided on the piston 21, and the piston 21 can be pulled out for replacement. Different pistons 21 can be provided with annular grooves 211 of different depths. The annular grooves 211 of different depths are used to limit the roller 233 at the rear end of the clamping jaw 23 to control the maximum opening angle of the clamping jaw 23 to meet the needs of clamping long roll materials of different diameters. Due to the elastic force of the elastic ring 22, the clamping force of the clamping jaw on the long roll material can be maintained.
[0025] like Figure 4 As shown, the utility model also provides an automatic coil cutting machine, which includes the coil fixing assembly of the automatic coil cutting machine as described above. A stop shoulder 41 is provided at one end of the rotating mandrel 4 of the automatic coil cutting machine close to the aligning cylinder 1 .
[0026] It should be understood that all the above embodiments are illustrative rather than restrictive, and any modifications, equivalent changes and modifications made by those skilled in the art to the specific embodiments described above under the conception of the present invention are still within the scope of the technical solution of the present invention.
