Description

Novel processing technology for book backs of adhesive binding machine

Technical Field

The invention relates to the technical field of book binding products, in particular to a novel book back processing technology of a binding machine.

Background

Books are important carriers for the development of human social culture. The paper can become a exquisite finished book after printing, binding and cutting. Book binding forms are many, and perfect binding is one of the most popular forms of modern applicability. Book binding generally needs to be folded into a book, assembled into a book, then enters a binding and covering machine, and then is subjected to processes of book block aligning, back milling, groove drawing, book brushing, gluing, cover and indentation feeding, compaction and clamping forming and the like.

The procedures of back milling, groove drawing, book brushing and the like before gluing the book block are the processing technology of the glued and bound book back. The processing quality of the book back directly determines the finishing quality of subsequent processes of gluing, clamping and forming and the like.

The basic form of the processing technology of the existing glue binding book covering machine is shown in figure 5, a book clamping device clamps the middle upper part of a whole book block, and the book back extends out of the lower part of the book clamp so as to facilitate the processing of the book back. And as the book end moves along the slide rail, the book back enters a rough milling functional area, and then the rough milling cutter disc can mill a part of the book block lower than the milling cutter to form a new book block consisting of single sheets of paper. Then the book block enters a finish milling part, and the milling plane left after rough milling is further finely milled, so that the requirement of gluing can be met. The book block after the finish milling can enter into the drawing groove process, the process can utilize the drawing groove cutter on the back of the book that has been finish milled smoothly, process out and have spaced horizontal slot, and the brush structure of later drawing groove part can clear up the wastepaper that produces after the drawing groove.

As mentioned above, the book back processing technology in this way still has the following disadvantages:

1. through a series of book back processing processes, the book back which is originally clamped and tightly attached by the book clamp becomes loose, paper scraps generated by the slot-drawing knife can be clamped by the gap of the book block, so that the brush can not clean up, and finally the glue on the book back is not full and uniform, so that the forming quality of the book back is affected.

2. The back is bulky, which causes the compacted boundary dimension of the upper cover to change, such as dimension a in fig. 6, resulting in an unattractive finished back and unstable quality.

3. The book back is bulky, and the residual air between the inner pages can not be discharged when being clamped and formed after gluing, so that glue holes and bubbles are easily formed in the glue layer of the book back, and the gluing is not firm directly.

4. The bulking of the book back directly affects the subsequent gluing quality. Glue is easy to permeate into gaps of inner pages of the book block during gluing, uneven glue permeating layers can be seen in a finished book in the process of turning and using, which is not allowed by book gluing and binding process standards, and meanwhile, glue permeating can thicken a book back, so that the cutting precision of a downstream three-side book trimmer is directly influenced.

In view of this, we propose a new spine processing technique for a glue stapler.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example (b): as shown in fig. 1 and 2, the novel processing technology for the book back of the adhesive binding machine comprises the following steps:

the method comprises the following steps: clamping the middle-upper part of the whole book block through the book clamp, and enabling the book back of the whole book block to leak out of the bottom of the book clamp; the book clamping device clamps and fixes the whole book core and is driven by the traction device to move.

Step two: the book clamping device moves along the direction of the slide rail, the book back of the whole book block enters the rough milling area A, the book block of which the bottom is lower than the milling cutter is milled by a rough milling cutter disc in the rough milling area A, and the book back of the whole book block is tidily changed from irregularity; the driving device drives the rough milling cutter disc to rotate to roughly mill the book back of the book block coming to the top of the rough milling cutter disc so as to remove the irregular part of the book back;

step four: after passing through the slot drawing area B, the whole book block enters a finish milling area C, and a finish milling cutter disc of the finish milling area C mills a plurality of transverse grooves at the book back of the whole book block to form fibers with thick and long paper; the adhesive can be better adhered with the adhesive solution in the subsequent steps, the adhesive firmness is further improved, and the specification stability of the subsequent cut book is further improved.

Step five: the whole book block finally enters a book back compaction area D, and air in the page space is squeezed and removed by a pressurizing device of the book back compaction area D; therefore, the pages in the whole book back are tightly attached and tidy, the problem that the book back is fluffy is thoroughly solved, and the problems that the finished book back is not attractive in forming and unstable in quality and the like due to the fact that the size specification of the compacted boundary of the upper cover is changed due to the fluffy book back, such as the size a in figure 6.

And step three, the maximum milling amount after the slot drawing station carries out the finish milling is 0.2 mm, and the finish milling process after the slot drawing can mill the book back with the change in the slot drawing again into a book back plane which meets the requirements of the subsequent process.

Example (b): as shown in figures 3 and 4, the novel processing technology for the book back of the adhesive binding machine comprises a pressurizing device in the fourth step, wherein the pressurizing device comprises a base 1 (which plays a bearing role for the device), a vertical shaft 2 (which plays a bearing role for a front pressure plate), a rear pressure plate and a front pressure plate (which play a role in clamping the book back of a book block so as to remove air in pages of the book), the vertical shaft 2 is rotatably connected to one side of the base 1 through a bearing, the rear pressure plate comprises a rear upper pressure plate 3 and a rear lower pressure plate 4, the front upper pressure plate 5 and the front lower pressure plate 6 are arranged on the other side of the base 1, the rear upper pressure plate 3 and the rear lower pressure plate 4 are movably sleeved outside the top end of the rear pressure plate 7, a first swing arm 11 is fixedly sleeved at the top end of the vertical shaft 2, a front pressure plate shaft 9 penetrates through one end of the first swing arm 11, the front upper pressure plate 5 and the front lower pressure plate 6 are movably sleeved outside the first swing arm 11, the fixed cover in the middle of 2 outsides of vertical scroll is equipped with second swing arm 12, and the one end of second swing arm 12 is connected with aperture adjustment cover 13, and one side of aperture adjustment cover 13 is connected with adjustment swivel nut 14, and adjustment swivel nut 14 internal thread is connected with an adjusting screw 15, and the opposite side of aperture adjustment cover 13 is equipped with dish spring 16 and fills up the cover 17, and one side of filling up the cover 17 is equipped with round nut 18 and a piece 20, and a piece 20 links firmly with base 1 through mounting panel 19.

The support 10 is rotatably connected inside the support block 20 through a bearing, and one end of an adjusting screw 15 sequentially penetrates through the adjusting screw sleeve 14, the opening adjusting sleeve 13, the disc spring 16, the cushion cover 17 and the round nut 18 to be fixedly connected with the support 10; the adjusting shaft sleeve 14, the opening adjusting sleeve 13, the disc spring 16, the positioning cushion cover 17 and the round nut 18 are arranged on the adjusting shaft sleeve 14 in an axial matching mode and synchronously move axially along with the adjustment and rotation of the adjusting screw rod 15. In the process of the adjustment, the elastic structure of the disc spring 16 also forms the function of overload protection; the other end of the adjusting screw 15 is a mechanical structure connected with a wrench for adjustment, so that force transmitted by the adjusting screw 15 can more stably act on the opening adjusting sleeve 13 in the adjusting operation process, and the accuracy and stability of pressure plate adjustment are improved; the specific process is as follows: the adjusting screw 15 is put into rotation, which causes the adjusting screw 14, which is threadedly engaged with the adjusting screw 15, to move in the axial direction on the outside thereof. And because the opening adjusting sleeve 13 and the adjusting screw sleeve 14 are relatively fixed, the axial movement of the adjusting screw sleeve 14 acts on the second swing arm 12 through the opening adjusting sleeve 13, so that the second swing arm swings around the vertical shaft 2 as a central point. The movement of the second swing arm 12 affects the first swing arm 11 and the front platen assembly mounted on the first swing arm 11 through the vertical shaft 2, so that the front platen assembly performs a rotational swing motion around the vertical shaft 2 as a center, i.e., the front platen assembly moves closer to or away from the rear platen assembly.

The rear platen shaft 7 and the front platen shaft 9 are both eccentric shafts, and the bottom of the rear platen shaft 7 and the top of the front platen shaft 9 are both sleeved with eccentric shaft control parts 8; through the adjustment of the eccentric shaft control part 8, the relative displacement of the centers between the rear lower pressing plate 4 and the rear upper pressing plate 3 and between the front upper pressing plate 5 and the front lower pressing plate 6 can be adjusted, so that the thickness of the front and rear pressing plate assemblies can be adapted to the thickness of the book holder.

The operation steps of the pressure regulating device are as follows:

the adjusting screw 14 is rotated to adjust the distance between the front pressure plate and the rear pressure plate to the thickness matched with the book block, at the moment, the front upper pressure plate lightly touches the outer side of the outer clamping plate body of the book clamp, and the book block clamped by the book clamp can pass through the book block in a tangent mode.

The front lower platen 6 is adjusted by rotating the eccentric shaft control 8 so that it lightly compacts the back of the book block.

After the book back compaction device is set, the book block is clamped by the book clamp and is sent from the book back milling station, the book block enters the book back compaction procedure after rough milling, groove drawing and finish milling, and the book back passing the previous procedure is compacted by the station, so that the book back meets the requirements of compactness and orderliness, and immediately enters the subsequent gluing and cover applying procedures. Because the time for gluing after the book back compaction operation is very short and no extra working procedure is needed, the book back can reach the tightest and tidy state during gluing, thereby solving the quality problems of the existing book back processing technology, such as glue holes, substandard line pressing specification, glue solution entering the book block and the like.
