Description

Technical Field

[0001] The utility model relates to the field of cutting devices, in particular to a cutting device for backing strips and lining paper of book cover films. Background Art

[0002] In the field of book binding and protection, book film is a common book protection material with increasingly wide applications. Book film is glued to the cover of the book to protect the book and reduce the damage of the book such as wear or folding. In order to ensure that the book film can be accurately and flatly attached to the book cover, especially the spine of the book, a special cutting device is required to accurately cut the book film. Therefore, China has authorized a utility model patent (Announcement No.: CN215551709U) to disclose a tear-off seam cutting device for the backing paper of the book film. The device first cuts an easy-tear seam on the backing paper, and then presses the backing paper and the film body together, which can avoid scratching the film body during cutting, improve the yield rate, and make processing more convenient.

[0003] In the above device, the spacing between a pair of scribers can also be adjusted according to the size requirements of the easy-tear seam, but there are still some shortcomings in the process of adjusting the spacing between scribers by the device: when adjusting the spacing between two scribers, the existing device requires the operator to first unscrew the bolts and completely remove the scribers and the pressure plate from the connecting frame, and then the operator needs to use a block gauge to accurately set the distance between the scribers, which requires the screw holes of the block gauge to be accurately aligned with the screw holes on the scribers and the connecting frame before they can be fixed by bolts. The entire adjustment process is relatively cumbersome and time-consuming, affecting work efficiency. Therefore, in view of the above situation, a device for cutting book cover backing paper is proposed. Utility Model Content

Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A cutting device for book cover backing paper comprises a connecting plate 1, two pairs of screw rods 2 and two pairs of support plates 4, wherein the two pairs of screw rods 2 are respectively arranged on the outer walls on both sides of the connecting plate 1, an adjusting plate 3 is arranged on one pair of the screw rods 2, one side of the adjusting plate 3 abuts against the outer wall of the connecting plate 1, a first pressing plate 5 is sleeved on one side of the pair of screw rods 2 close to the adjusting plate 3, and four limit blocks 501 are arranged on one side of the first pressing plate 5.

[0029] The adjusting plate 3 is provided with an assembly groove 301, and the assembly groove 301 cooperates with a pair of screw rods 2. Four limiting grooves 302 are provided on the corresponding two sides of the adjusting plate 3, and the limiting grooves 302 cooperate with the limiting blocks 501. A positioning plate 303 is integrally formed at the bottom of the adjusting plate 3, and a positioning block 304 is set at the bottom of the pair of positioning plates 303.

[0030] The two pairs of support plates 4 are respectively arranged at the bottom of the outer walls on both sides of the connecting plate 1 . A plurality of positioning grooves 401 are equidistantly formed on the top of the support plates 4 . The positioning grooves 401 cooperate with the positioning blocks 304 .

A pair of the screw rods 2 are both threadedly fitted with a nut 8, and the nut 8 is in conflict with one side of the second press plate 7.

[0032] By threading the nut 8 with the screw rod 2, the nut 8 can be rotated clockwise to move toward the side close to the connecting plate 1, thereby pushing the second pressure plate 7, the scriber 6 and the first pressure plate 5 to move, and causing the second pressure plate 7, the scriber 6 and the first pressure plate 5 to conflict with each other to ensure stability.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6A pair of circular holes are formed through the first pressing plate 5 , the scriber 6 and the second pressing plate 7 , and the first pressing plate 5 , the scriber 6 and the second pressing plate 7 are matched with the screw rod 2 through the pair of circular holes.

[0034] A pair of circular holes are provided on the first pressing plate 5 , the scriber 6 and the second pressing plate 7 so as to respectively sleeve the first pressing plate 5 , the scriber 6 and the second pressing plate 7 onto a stack of screw rods 2 .

[0035] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6 The adjustment plate 3 is a plate structure in the shape of a "J" character, and the assembly groove 301 is in the shape of an inverted "U".

[0036] The positioning plate 303 and the adjusting plate 3 are integrally formed to form a "J"-shaped structure. After the adjusting plate 3 is installed, its bottom contacts the top of the supporting plate 4.

[0037] Reference Figure 3 and Figure 4 The limiting block 501 is a rectangular block, and the shape and size of the limiting groove 302 are adapted to the limiting block 501.

[0038] By providing the limiting block 501 , after tightening the nut 8 , the first pressing plate 5 can be horizontally moved so that the limiting block 501 can be inserted into the limiting groove 302 , thereby further ensuring the stability of the adjusting plate 3 .

[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A movable groove is formed between the connecting plate 1 and the pair of supporting plates 4, and the first pressing plate 5, the scriber 6 and the second pressing plate 7 can all be horizontally moved in the movable groove.

[0040] By forming the movable groove, after reducing the number of installed adjustment plates 3, it can be ensured that the first pressure plate 5, the scriber 6 and the second pressure plate 7 can move smoothly and contact the adjustment plate 3 close to the connecting plate 1, and the movable groove can serve as a moving channel for the first pressure plate 5, the scriber 6 and the second pressure plate 7.
