Once the rotating roller finishes winding the film, it is often necessary to pre-close the motor, then disassemble the wound film on the rotating roller, and replace it with a new reel before proceeding with subsequent winding. In this process, closing the motor, disassembling the wound reel, and replacing the new core will all take a lot of time, resulting in a reduction in winding efficiency. Summary of the Utility Model

[0023] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0024] Referring to Figures 1-4 as shown, a metallized film winding device includes a C-shaped mounting seat 1 and a multi-station winding mechanism arranged on the innermost inner wall of the mounting seat 1. One side of the mounting seat 1 is fixed with a mounting plate 6, and a power mechanism cooperating with the multi-station winding mechanism is arranged on the mounting plate 6;

[0025] The multi-station winding mechanism includes a movable seat 4 with an open end. The open end of the movable seat 4 is rotatably arranged on the inner side wall of the movable seat 4. Two rotating rollers 2 are symmetrically and vertically rotatably arranged at the closed end of the movable seat 4, and a reel 3 is detachably arranged on the rod body of the rotating roller 2;

[0026] The power mechanism includes a second motor 7 installed on one side of the mounting plate 6. A driving gear 8 is tightly sleeved on the output shaft of the second motor 7, and a driven gear 9 meshing with one of the driving gears 8 is tightly sleeved on the rod body of the rotating roller 2;

[0027] Through the setting of the multi-station winding mechanism, when the second motor 7 is started, the output shaft of the second motor 7 acts on the driving gear 8 to continuously rotate and meshes with the driven gear 9 on the rod body of one of the rotating rollers 2, thereby continuously rotating the rotating roller 2 so that the reel 3 on the rod body of the rotating roller 2 continuously winds the film;

[0028] When the winding drum 3 finishes winding the film and the second motor 7 is stopped, the movable seat 4 is rotated by 180 degrees to change the positions of the two rollers 2, so that the wound winding drum 3 can be replaced, and a new winding drum 3 can be replaced at the position of the second motor 7. Thus, it is convenient for the operator to restart the second motor 7 in a short time and continue winding the film on the new winding drum 3. For the originally wound winding drum 3, another person can disassemble it separately while the winding work is in progress. Therefore, while not affecting the continuous winding operation of the film, the new winding drum 3 can be replaced, improving the work efficiency.

[0029] Furthermore, referring to Figure 3 As shown, it is worth noting that a first motor 5 is installed on the back of the mounting seat 1, and the output shaft of the first motor 5 rotates through the mounting seat 1 and is fixedly connected to the inner wall of the movable seat 4;

[0030] When the first motor 5 is started, the output shaft of the first motor 5 drives the rotation of the movable seat 4, so that the movable seat 4 drives the two rollers 2 to rotate by 180 degrees.

[0031] Furthermore, referring to Figure 2 As shown, it is worth noting that a positioning groove 10 is formed in the rod body of the roller 2, and a slider adapted to the positioning groove 10 is fixedly installed on the inner wall of the winding drum 3;

[0032] Through the arrangement of the slider and the positioning groove 10, the winding drum 3 is slidably connected to the rod body of the roller 2, so that the winding drum 3 can rotate together when the roller 2 rotates.

[0033] Furthermore, referring to Figures 2-4 As shown, it is worth noting that a contraction groove 11 is horizontally penetrated in the inner wall at the end of the roller 2, a positioning member is slidably arranged in the contraction groove 11, a penetration and contraction channel 14 communicating with the contraction groove 11 is arranged in the inner wall of the roller 2, an extrusion member cooperating with the positioning member is arranged in the penetration and contraction channel 14, and a transmission member cooperating with the extrusion member is arranged in the movable seat 4;

[0034] The positioning member includes a limiting block 12 slidably arranged inside the contraction groove 11, and a pressure receiving groove 13 with a right trapezoidal cross section is formed in the inner wall of the limiting block 12;

[0035] The extrusion member includes an extrusion screw 15 slidably arranged in the penetration and contraction channel 14. One end of the extrusion screw 15 penetrates into the pressure receiving groove 13 and is fixed with a semi-sphere, and the semi-sphere contacts the inclined inner wall of the pressure receiving groove 13;

[0036] The transmission member includes an arc-shaped internal toothed plate 17 disposed on one side inside the movable seat 4 and an arc-shaped external toothed plate 18 disposed on the other side inside the movable seat 4. Both the arc-shaped internal toothed plate 17 and the arc-shaped external toothed plate 18 are fixedly connected to the inner wall of the mounting seat 1. The other end of the extrusion screw 15 is threadedly inserted into the inner side of the movable seat 4 and is fixed with a movable gear 16. When the movable gear 16 rotates circumferentially, it can sequentially engage with the inner tooth surface of the arc-shaped internal toothed plate 17 and the outer tooth surface of the arc-shaped external toothed plate 18;

[0037] An activity slot adapted to the contraction slot 11 is formed on the surface at the end of the roller 2. A pull tab 21 fixedly connected to the limiting block 12 is slidably disposed in the activity slot. A fixing piece 19 is vertically fixed at the end of the roller 2. A return spring 20 is fixed between the fixing piece 19 and the arc-shaped external toothed plate 18;

[0038] Through the arrangement of the positioning member, the extrusion member and the transmission member, when the movable seat 4 rotates 180 degrees and the acting roller 2 rotates to the side away from the second motor 7, the movable gear 16 in the transmission member can pass through the arc-shaped internal toothed plate 17 and engage with it during this process, so that the extrusion screw 15 contracts into the internal threading channel 14 when it is forced to rotate, and thus no longer extrudes the inclined inner wall of the pressure receiving groove 13, so that the pull tab 21, under the elastic force of the return spring 20, carries the limiting block 12 to reset and contract inside the contraction slot 11, automatically releasing the positioning effect on the reel 3, so as to facilitate the rapid replacement of the reel 3 by the operator;

[0039] Conversely, after the replacement of the reel 3 is completed and the movable seat 4 is continuously rotated 180 degrees until the acting roller 2 rotates to a position close to the second motor 7, the movable gear 16 in the transmission member can pass through the arc-shaped external toothed plate 18 and engage with it during this process, so that the extrusion screw 15 contracts into the pressure receiving groove 13 when it is forced to rotate, and thus extrudes the inclined inner wall of the pressure receiving groove 13, so that the limiting block 12 is extruded to slide out of the inside of the contraction slot 11 and compress the return spring 20 to deform, so that the limiting block 12 abuts against the end face of the reel 3 to achieve the automatic locking effect of the reel 3.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
