Description

Technical Field

[0001] The utility model mainly relates to the technical field of raw foil production, and specifically relates to a buffer device for a winding rack of a raw foil machine. Background Art

[0002] The preparation process of electrolytic copper foil is to rotate a conductive cathode roller at a certain speed in an electrolytic cell filled with copper sulfate solution. An anode plate is installed at the bottom of the electrolytic cell. Under the traction of the electric field, copper ions are deposited on the cathode roller. Then the cathode roller rotates out of the electrolytic cell, and the copper foil is peeled off from the cathode roller and wound up. Usually, a winding shaft is used for winding the copper foil.

[0003] When the winding shaft is full of copper foil during winding, it is necessary to push the winding shaft out of the winding rack to wind the copper foil. There is a baffle at the front end of the existing winding rack track to prevent the winding shaft from falling directly due to too fast speed when it is pushed out, which may cause damage to the copper foil and the winding shaft. However, although the baffle restricts, when the winding shaft is pushed out at a relatively fast speed and directly collides with the baffle, the winding shaft and the baffle may be damaged, reducing the service life of the equipment. Summary of the Utility Model

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution significantly different from the existing technology. It mainly provides a buffer device for a winding rack of a raw foil machine to solve the technical problem that when only the baffle is used to restrict the winding shaft during unwinding, due to the lack of buffering, the winding shaft contacts the baffle at too fast a speed, which is likely to cause damage to the baffle and the winding shaft.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0006] A buffer device for a winding rack of a raw foil machine, including a main body of the winding rack. A support block is arranged above the main body of the winding rack. A winding shaft is arranged above the support block. A limiting block group for guiding the winding shaft to be pushed out is arranged above the support block. A buffer block for buffering and reducing the moving speed of the winding shaft pushed out of the main body of the winding rack is arranged on the support block.

[0007] Preferably, the limiting block group includes a first limiting block, a second limiting block, a third limiting block and a fourth limiting block. The first limiting block, the second limiting block, the third limiting block and the fourth limiting block are arranged adjacent to each other above the support block in sequence.

[0008] Preferably, a first winding track is arranged between the first limiting blocks, and second winding tracks are respectively arranged between the second limiting block, the third limiting block and the fourth limiting block.

[0009] Preferably, the first winding track and the plurality of groups of second winding tracks are sequentially connected to each other, and the first winding track is narrower than the second winding track.

[0010] Preferably, a guide block is provided on the winding shaft, and the guide block rolls along the first winding track and the second winding track.

[0011] Preferably, a buffer block is arranged between the fourth limiting blocks, and the upper surface of the buffer block is arc-shaped.

[0012] Preferably, a baffle is arranged above the support block, and the baffle is arranged on one side of the buffer block.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: when the winding shaft is pulled outward, the winding shaft is moved by rotating along the winding track through the guide blocks arranged at both ends. When the winding shaft moves to one end of the winding track and is about to separate from the winding track, the guide block will move to above the buffer block with an arc-shaped surface. The circular arc surface of the guide block forms a gentle slope to reduce the moving speed of the guide block, thereby buffering and slowing down the pulled winding shaft, and the highest point of the buffer block is only slightly lower than the highest point of the baffle. In this way, the guide block guided by the buffer block will roll directly to the top of the baffle at a low speed without colliding with the baffle. This can protect the raw foil machine and the winding shaft, while avoiding high-speed collisions and eliminating the risk of folding the raw foil winding shaft when it is rewound, thereby reducing the waste of copper foil.

[0020] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosed content of the present utility model more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixedly provided on" another element, it can be directly on the other element or there can be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Please refer specifically to the attached Figures 1 - 4 , a buffer device for a winding frame of a copper foil generator, which includes a winding frame main body 1. A support block 2 is arranged above the winding frame main body 1. A winding shaft 3 is arranged above the support block 2. A limiting block group for guiding the winding shaft 3 to be pushed out is arranged above the support block 2. A buffer block 9 for buffering and decelerating the moving speed of the winding shaft 3 pushed out of the winding frame main body 1 is arranged on the support block 2.

[0024] The specific operation process of the present utility model is as follows: When the winding shaft 3 is wound to a full roll state, the winding shaft 3 is pulled outwards. The winding shaft 3 is restricted to move linearly outwards through the limiting block group. When the winding shaft 3 is about to move out of the limiting block group, the winding shaft 3 moves above the buffer blocks 9 arranged on both sides. The surface of the buffer block 9 is arc-shaped, and the moving winding shaft 3 is buffered and decelerated through the slope of the arc. When the winding shaft 3 moves to the highest end of the buffer block 9, the moving speed of the winding shaft 3 is reduced at this time, and the arc-shaped setting of the buffer block 9 allows the winding shaft 3 to move upwards, avoiding collision with the baffle 10 on one side of the winding frame main body 1, and directly moving out of the winding frame main body 1 to achieve recycling.

[0025] Please refer to Figures 1 - 3, the limiting block group includes a first limiting block 5, a second limiting block 6, a third limiting block 7, and a fourth limiting block 8. The first limiting block 5, the second limiting block 6, the third limiting block 7, and the fourth limiting block 8 are sequentially and adjacently arranged above the support block 2. A first winding track 11 is provided between the first limiting blocks 5, and second winding tracks 12 are respectively provided between the second limiting block 6, the third limiting block 7, and the fourth limiting block 8. The first winding track 11 and the multiple groups of second winding tracks 12 are sequentially interconnected with each other. The first winding track 11 is narrower than the second winding track 12. A guiding block 4 is provided on the winding shaft 3, and the guiding block 4 rolls along the first winding track 11 and the second winding track 12.

[0026] The guiding block 4 is rotatably connected to both ends of the winding shaft 3. The guiding block 4 is located between the first winding track 11 and the second winding track 12. When the winding shaft 3 is winding, the guiding block 4 is inside the first winding track 11. The track of the first winding track 11 is relatively narrow, and the first limiting blocks 5 on both sides are in contact with the guiding block 4 to prevent the winding shaft 3 from shaking during winding. When the winding shaft 3 is fully wound and unrolled, the winding shaft 3 is pulled outwards, and the guiding block 4 will roll along the first winding track 11 and move into the second winding track 12. The second winding track 12 is wider, and the second limiting block 6, the third limiting block 7, and the fourth limiting block 8 provided on both sides will not be in contact with the guiding block 4, so as to prevent the guiding block 4 from colliding with the second limiting block 6, the third limiting block 7, and the fourth limiting block 8 during rolling and causing wear. The first limiting block 5, the second limiting block 6, the third limiting block 7, and the fourth limiting block 8 are all used to limit the movement of the guiding block 4 and prevent the guiding block 4 from derailing during movement.

[0027] Please refer to Figure 4 , a buffer block 9 is provided between the fourth limiting blocks 8. The upper surface of the buffer block 9 is arc-shaped. A baffle 10 is provided above the support block 2, and the baffle 10 is arranged on one side of the buffer block 9.

[0028] When the guiding block 4 rolls into the second winding track 12 between the fourth limiting blocks 8, the fourth limiting block 8 moves above the buffer block 9. The slope of the arc surface on the buffer block 9 is used to buffer and decelerate the rolling guiding block 4, and drive the guiding block 4 to rise along the arc surface. The highest point of the arc surface of the buffer block 9 is only slightly lower than the highest point of the baffle 10. In this way, the guiding block 4 guided by the buffer block 9 to rise will continue to roll above the baffle 10 for unrolling, rather than hitting the baffle 10 to decelerate and then passing over the baffle 10 for blanking, thus reducing the impact between the guiding block 4 and the baffle 10.

[0029] The above exemplary description of the present utility model is made in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
