[0027] The utility model provides the following technical solutions:

[0028] Example 1

[0029] Combine Figures 1 to 7 A double-station coil unwinding device includes a base 1, a support platform 2 is rotatably connected to the top of the base 1, a double-axis unwinding motor 5 is fixedly connected to the top of the support platform 2, a switching mechanism 3 is provided on both sides of the double-axis unwinding motor 5, and a positioning mechanism 4 is provided on the outside of the base 1;

[0030] The switching mechanism 3 includes a support base 31, which is fixedly connected to the top of the support platform 2. A double-axis cylinder 32 is fixedly connected inside the support base 31. Both ends of the double-axis cylinder 32 are fixedly connected to movable blocks 33. The movable block 33 is movably connected to a movable arm 34 on the side away from the double-axis cylinder 32. A pushing shaft 36 is fixedly connected inside the movable arm 34. A positioning shaft 35 is fixedly connected to the top of the support platform 2. A connecting base 37 is fixedly connected to the top of the support platform 2. A support shaft 38 is rotatably connected inside the connecting base 37. One end of the support shaft 38 is fixedly connected to the unwinding material rack 39. The outer wall of the support shaft 38 is slidably connected to a gear sleeve 1 302. A long block 301 is provided inside the gear sleeve 1 302. Gear sleeve 2 303 is provided on both sides of the unwinding double-axis motor 5.

[0031] Furthermore, the output end of the unwinding dual-axis motor 5 is fixedly connected to an output shaft, and the second gear sleeve 303 is fixedly connected to the outer wall of the output shaft, so that the unwinding dual-axis motor 5 can drive the second gear sleeve 303 to rotate through the output shaft.

[0032] Furthermore, an annular notch is provided on the outer side of the gear sleeve 1 302 , and the driving shaft 36 is movably connected to the inner wall of the annular notch, so that the driving shaft 36 can push the gear sleeve 2 303 to move through the annular notch.

[0033] Furthermore, a long opening is provided on the inner wall of the gear sleeve 1 302 , and the long block 301 is inserted into the inner wall of the long opening, so that the support shaft 38 can drive the gear sleeve 1 302 to rotate.

[0034] Furthermore, a rotating hole is provided inside the movable arm 34 , and the positioning shaft 35 is rotatably connected to the inner wall of the rotating hole, so that the movable arm 34 can change its angle under the action of the rotating hole.

[0035] Example 2

[0036] See Figures 1 to 7 , and on the basis of Example 1, the positioning mechanism 4 is further obtained to include a support plate 41, the support plate 41 is fixedly connected to the outside of the base 1, the side of the support plate 41 away from the base 1 is fixedly connected to a connecting frame 42, the bottom of the support platform 2 is fixedly connected to a positioning seat 1 44, the bottom of the connecting frame 42 is fixedly connected to a positioning cylinder 43, the top of the positioning cylinder 43 is fixedly connected to a V-shaped guide block 45, and the bottom of the support platform 2 is fixedly connected to a positioning seat 2 46, which can realize the positioning of the support platform 2 while realizing the rotation of the support platform 2.

[0037] Furthermore, the outer shape of the V-shaped guide block 45 matches the inner wall shape of the positioning seat 2 46 and the positioning seat 1 44, and the positioning seat 1 44 is movably connected to the inner wall of the positioning seat 2 46, so that the V-shaped guide block 45 can position the positioning seat 2 46, so that the support platform 2 will not rotate easily.

[0038] In actual operation, when this device is used, the dual-axis cylinder 32 is started to work, and the output end of the dual-axis cylinder 32 can push the movable block 33 to move, and the movable block 33 drives the movable arm 34 to move along the axis point of the positioning shaft 35, and the movable arm 34 can push the gear sleeve 1 302 to move through the driving shaft 36, and the gear sleeve 1 302 can slide on the outside of the support shaft 38, and the long block 301 can move with the limiting groove inside the support shaft 38, and when the gear sleeve 1 302 and the gear sleeve 2 303 are in meshing state, the unwinding dual-axis motor 5 can work to drive its output shaft to rotate, and the output shaft drives the gear sleeve 2 303 to rotate, and the gear sleeve 2 The unwinding rack 39 can be driven to rotate by the sequential cooperation of the gear sleeve 1 302, the long block 301 and the support shaft 38. Similarly, when the gear sleeve 1 302 is not engaged with the gear sleeve 2 303, the gear sleeve 2 303 cannot drive the gear sleeve 1 302 to rotate. Therefore, by starting the double-axis cylinder 32, the unwinding rack 39 on the right can be controlled to rotate. At this time, the coiled material on the outside of the unwinding rack 39 rotates to achieve the purpose of unwinding, and the unwinding rack 39 on the left does not rotate, so that it is convenient for the staff to load the unwinding rack 39 on the left and insert the coiled material to the outside of the unwinding rack 39 on the left for loading.

[0039] When the unwinding of the unwinding material rack 39 on the right is completed, the positioning cylinder 43 can be started to work, and the positioning cylinder 43 can drive the V-shaped guide block 45 to descend, so that the V-shaped guide block 45 no longer gets stuck in the internal limit of the positioning seat 2 46. At this time, the support platform 2 can be rotated along the axis point of the base 1 and the base can be rotated 180 degrees, so that the positioning cylinder 43 can be started again to drive the V-shaped guide block 45 to rise, so that the V-shaped guide block 45 can be stuck in the interior of the positioning seat 1 44, thereby achieving the purpose of loading and unloading different unwinding material racks 39, and under the mutual cooperation of the positioning seat 1 44, the V-shaped guide block 45 and the positioning seat 2 46 can ensure stability during the unwinding process, and ensure that the unwinding work can be carried out stably.

[0040] Two front and back roll material unwinding racks 39 are used. When the front roll material unwinding rack 39 is in use, the back roll material unwinding rack 39 can store the roll material to be used.

[0041] When the front roll is used up, the bottom plate is rotated 180 degrees and the rear roll is moved to the front for use. At this time, when the equipment is operating normally, the new roll is loaded at the back.

[0042] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
