Description

Front cover clamping device of cementing machine

Technical Field

The invention relates to the technical field of cover indentation processing of a cementing machine, in particular to a clamping device for a cover of the cementing machine.

Background

The existing glue binding machines are generally divided into two types, one is a glue binding machine without an indentation mechanism, and the other is a glue binding machine with an indentation mechanism.

For the glue binding machine without the indentation mechanism, if only a single glue binding machine is adopted and the glue binding machine is not matched with other equipment, two conditions exist in glue binding of books and periodicals, firstly, the books and periodicals have no page turning marks, the appearance can be seen at a glance, the appearance of the books and periodicals is one element less than that of products in a large factory, and the books and periodicals are not products bound by a regular printing factory; products that are less profound and textured than indented; secondly, books and periodicals are not processed by indentation, the front cover of the books and periodicals is opened, and no page turning boundary line exists between the second cover and the flyleaf, so that the following multiple secondary feelings can be caused: A. for a new book, the second cover is opened without applying pressure by external force, and can be automatically closed, so that a reader can embody poor results; B. if the first page turning is performed by pressing the palm of a reader, the pressing position is quite random, finally, the books and periodicals generate palm indentations and bring secondary quality feeling; C. if the inner page of the book and periodical is 80 g thick paper, the flyleaf can be taken up by turning over the cover, the adhesive joint of the first inner page and the second inner page can be seen, the same problem exists between the last page and the third cover, and the reader has secondary taste.

For a glue binding machine without an indentation mechanism, if books and periodicals with indentations are to be produced, production equipment of the glue binding machine is matched with the indentation machine at the same time, and the production operation is as follows: the manual cooperation is the front cover indentation earlier, binds with the cementing machine cooperation again, and the machine purchase cost of two equipment is high, and the study cost is high, and the cost of labor is high, and the time cost is high, and the rejection rate is also high simultaneously.

For the glue binding machine with the indentation mechanism, the operation is usually that the indentation is firstly carried out and then the glue is applied. But has the following disadvantages: A. the alignment has errors, and the defective rate exists when the two mechanisms are in butt joint with errors; B. the indentation mechanism is an independent system, so that the production cost is high; C. the hob impression is not straight sometimes, and the cover is possibly deviated when being sent to the cover clamp by the transmission mechanism, so that the impression position is not the book turning position, and the rejection rate is high.

In the embodiment, when the four electric push rods are all contracted to the shortest, the first shaping block 3 and the second shaping block 4 connected with the electric push rods are all horizontally placed on the first base plate 1, and at the moment, the clamping action of the two shaping blocks can be realized by operating the clamping motor 5, so that the clamping function of books and periodicals is completed; when controlling electric putter control switch for four electric putter extend the same distance simultaneously, electric putter's top drives the outside of mobilizable two shaping pieces and lifts up, through pressing from both sides tight motor operation clamping action once more, realizes front cover indentation function. The electric push rod on one side can be controlled to realize indentation operation of one of the front cover and the back cover of the books and periodicals.

In the first to fourth specific embodiments, the lifting of the outer end portion of the two or one of the two shaping blocks is realized through a cam structure, a liftable X-shaped supporting structure and a telescopic electric push rod structure, so as to realize the making of book and periodical impressions. In practical operation, the structure for lifting the outer end of one or both of the two shaping blocks includes but is not limited to the above structure, and lifting can be realized by a hydraulic device, and any lifting structure capable of realizing the above effects is within the protection scope of the present invention. The invention is not limited to the above embodiments, and any person can derive various products such as other lifting structures and the like according to the teaching of the invention. All equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
