Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of book production, specifically to a book core back paper strip conveying and cutting back mechanism. BACKGROUND

[0002] In the book core processing process, the back paper strip as an important part of the book core, the automation and precision of its conveying and cutting process are crucial to improve the production efficiency and quality of the book core. The traditional book core back paper strip conveying and cutting method mostly relies on manual operation or semi-automatic equipment, which has many drawbacks.

[0003] In terms of conveying, manual conveying of back paper strips not only has high labor intensity and low efficiency, but also is difficult to ensure the stability and continuity of conveying. Due to the instability of manual operation, the back paper strip may have uneven speed and positional deviation during the conveying process, which may affect the precision of the subsequent cutting process and even cause production accidents. Although semi-automatic equipment can reduce the labor intensity to some extent, its conveying system has poor adaptability and is difficult to handle back paper strips of different specifications and materials, and may also have phenomena such as jamming and slipping during the conveying process, affecting the production efficiency and product quality.

[0004] The cutting link also faces challenges. The traditional manual cutting method relies on the experience and skills of the operator, and the precision and consistency of the cutting are difficult to guarantee. Different operators have different cutting methods and intensities, resulting in different lengths and uneven cuts of the back paper strip, which not only affects the appearance of the book core, but also may affect the subsequent binding process. Although semi-automatic cutting equipment can achieve a certain degree of automatic cutting, its cutting mechanism has insufficient flexibility and stability, and is difficult to quickly adjust according to different production needs, and is prone to cutting failures, increasing the maintenance cost and downtime of the equipment.

[0028] The front surface of equipment bearing frame 1 is also fixedly installed with a marker pen 6, also called a big head pen, and the marker pen 6 is located on the conveying path of back paper strip, and the marker pen 6 can leave marks on the surface of back paper strip, and the marker pen 6 is installed on the seat body of the extension end of the air cylinder, and the tip of the marker pen is contacted or away from the back paper strip by the extension of the air cylinder, so that marks can be left on the back paper strip; in this way, the front and back order of the paper can be distinguished.

[0029] The top of equipment bearing frame 1 is provided with a back paper strip outlet 7 and a conveying belt 8, respectively, and the inlet end of the conveying belt 8 is connected with the back paper strip outlet 7, and the back paper strip cut by cutting module 5 is discharged from the back paper strip outlet 7 and conveyed to the subsequent equipment by the conveying belt 8;

[0030] The front surface of equipment bearing frame 1 is also rotatably connected with a material disc 9, and the material disc 9 carries a material roll of back paper strip, and the back paper strip is released by the material disc 9 when being pulled by belt conveying drive module 2 and conveying roller shaft 4.

[0031] The belt conveying drive module 2 comprises a driving roller shaft 21 rotatably connected to the front surface of the equipment bearing frame 1, a plurality of driven roller shafts 22 and a tensioning roller shaft 23, the surfaces of the driving roller shaft 21, the plurality of driven roller shafts 22 and the tensioning roller shaft 23 are collectively sleeved with a belt 24, the shape of the middle section of the belt 24 is adapted to the shape of the bottom distribution of the plurality of conveying roller shafts 4, the conveying of the back paper strip at this place relies on the friction between the belt 24 and the conveying roller shaft 4, and the driving roller shaft 21 is driven by a driving motor 25 installed on the back surface of the equipment bearing frame 1;

[0032] The cutting module 5 comprises a base 51 installed on the front surface of the seat plate 3, a cover plate 52 installed on the upper portion of the base 51, a cutter 53 slidingly connected between the base 51 and the cover plate 52, a cylinder 54 fixedly installed on the upper portion of the base 51, and the extension end of the cylinder 54 is connected with the cutter 53, and the inside of the base 51, the cover plate 52 and the cutter 53 are correspondingly provided with an inlet 55, an outlet 56 and a cutting opening 57, and the conveyed paper strip passes through the inside of the inlet 55, the cutting opening 57 and the outlet 56 in sequence, and when the paper strip is cut, the cylinder 54 drives the cutter 53 to move, so that the cutting opening 57 is dislocated from the inlet 55 and the outlet 56, a transverse cutting force is generated, and the paper strip is cut off;
