Detailed Implementation
[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0037] Example 1
[0038] Specific implementation examples Figure 1 , 2 As shown, the continuous foil roll connection structure is located between the foil tail 11 of the front foil roll 1 and the foil head 21 of the rear foil roll 2. The foil tail 11 and the foil head 21 overlap in the length direction, and a riveting structure 3 is provided in the overlapping area 12. The overlap length of the foil tail 11 and the foil head 21 includes 5-10cm. A reinforcing foil sheet 4 is provided between the inner ends of the foil tail 11 and the foil head 21, and / or between the inner ends of the foil head 21 and the foil tail 11.
[0039] Specifically, this connection structure is used to connect the foil head 21 and foil tail 11 of two foil rolls. The foil head 21 and foil tail 11 overlap and are riveted together by a riveting structure 3 for initial connection. Then, a reinforcing foil 4 is provided to cover it. The width of the reinforcing foil 4 is greater than the width of the overlapping area 12. The two sides of the reinforcing foil 4 are connected to the ends of the two foil rolls respectively to improve tensile strength. Moreover, the reinforcing foil 4 covers the front edge of the foil roll, effectively preventing cracking of the edge. The reinforcing foil 4 can be provided on only one side to control processing and material costs while ensuring good connection strength. Of course, it can also be provided on both sides to further improve the connection strength.
[0040] like Figure 2 As shown, the riveting structure 3 includes rivets 31 that pass through the foil head 21 and foil tail 11 simultaneously and are hammer-riveted together. The rivets 31 are evenly distributed in a matrix, and the distribution area is adapted to the shape of the reinforcing foil 4. The reinforcing foil 4 at least covers the distribution area.
[0041] Specifically, the riveting structure 3 is achieved using rivets 31 of the same material. These rivets 31 pass through both the foil head 21 and the foil tail 11, and are hammered into place, resulting in a good fixing effect. The even distribution of the rivets 31 ensures uniform stress distribution. The reinforcing foil sheet 4 covers the distribution area of the rivets 31, effectively mitigating cracking caused by the foil roll being pierced by the rivets 31 and hammered, and also preventing the rivets 31 from falling off due to insecure installation.
[0042] like Figure 1As shown, the reinforcing foil 4 includes a strip-shaped connecting section 41 extending along its width direction, which is simultaneously riveted to the foil head 21 or foil tail 11. Extension sections 42 are provided on both sides of the strip-shaped connecting section 41, and the extension sections 42 are riveted to the inner end of the foil head 21 or the inner end of the foil tail 11. The extension sections 42 are arc-shaped and evenly distributed along the length direction of the strip-shaped connecting section 41, with blank areas 43 formed between adjacent extension sections 42.
[0043] Specifically, the strip connecting section 41 partially covers the front end of the foil roll and partially covers the unoverlapping area behind the front end of another foil roll, thereby increasing tensile strength. The extension section 42 is integrally formed with the strip connecting section 41 and is connected to the corresponding foil head 21 and foil tail 11, further increasing tensile strength in the length direction. Simultaneously, the adjacent extension sections 42 are not completely connected, ensuring flexural strength. The extension section 42 is arc-shaped, forming a gourd-shaped reinforcing foil sheet 4. The blank area 43 alleviates the torsional tension on the foil head 21 and foil tail 11 after connection, improving flexural strength.
[0044] As an optimization of this embodiment, the reinforcing foil 4 is ring-shaped, surrounding the foil tail 11 and foil head 21 along the width direction. This arrangement on both the front and back sides improves connection convenience and connection strength.
[0045] In this embodiment, the reinforcing foil 4 and the rivets 31 of the riveting structure 3 are both adapted to the materials of the front roll foil 1 and the rear roll foil 2. This ensures conductivity and prevents the introduction of impurities.
[0046] The specific working principle is as follows: When connecting, the foil head 21 of the rear-rolled foil strip 2 is overlapped on the foil tail 11 of the front-rolled foil strip 1. Rivets 31 are applied at the overlapping position and the foil is hammered and riveted. Then, the reinforcing foil 4 is covered around the perimeter and hammered and riveted again to complete the connection and fixation of the foil head 21 and the foil tail 11.
[0047] Example 2
[0048] The working principle of this embodiment is basically the same as that of embodiment 1, except that a strip foil is also provided on the reinforcing foil 4.
[0049] like Figure 3 As shown, a strip of foil 5 is provided between the extension sections 42. The middle section of the strip of foil 5 vertically covers the strip connecting section 41 and is hammer-riveted together. The two ends are located in the blank area 43 and are hammer-riveted together with the foil head 21 or foil tail 11.
[0050] Specifically, a strip of foil 5 is vertically arranged on the reinforcing foil 4, and the strip of foil 5 is located in the blank area 43 to improve the tensile strength of the blank area 43.
[0051] Example 3
[0052] The specific working principle of the embodiment is basically the same as that of embodiment 1, and the difference lies in the shape of the extension section 42.
[0053] The specific implementation is as follows Figure 4 As shown in the figure, the shape of the extension section 42 is T-shaped, and the heights of adjacent extension sections 42 are different, that is, the horizontal sections 44 of adjacent T-shaped extension sections 42 are staggered and give way to each other, which ensures the connection strength of the extension section 42 and the foil roll, and the blank area 43 is located between the horizontal section 44 and the vertical section 45 of the extension section 42.
[0054] The specific embodiments described herein are merely illustrative of the spirit of the utility model. Those skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the utility model or exceed the range defined by the appended claims.
