Therefore following embodiment provides a quick replacement device of gravure press ink scraping sword, utilizes the handle to drive the pivot rotation that the cross-section is the D type, and it is used for the ink scraping sword to take out and put into to appear the clearance between two splint of centre gripping ink scraping sword, replaces original fastening screw fixed ink scraping sword to promote the efficiency that the ink scraping sword was changed. The tool changer in the following examples requires the following operating steps: 1, lifting a control handle (handle) of the two movable screws; 2. putting the scraper into the tool holder according to the conventional requirement; and 3, pressing down the handle (handle) and fixing the doctor blade by the two buckle screws. The total conditioning time was around 1 minute depending on the test.
The first embodiment is as follows:
as shown in fig. 1-5, the object of this embodiment is to provide a quick replacement device for a doctor blade of an intaglio printing press, which includes a blade holder 4, wherein a lower pressing plate 3 is disposed on an upper surface of the blade holder 4, the upper surface of the lower pressing plate 3 contacts with an upper pressing plate 1 through a backing plate 2, a rotating shaft 5 disposed on one side of the lower pressing plate 3 is disposed on the blade holder 4, a cross section of the rotating shaft 5 is D-shaped, and the rotating shaft 5 rotates to enable a protruding side of the D-shaped to face the lower pressing plate 3, so that a gap for accommodating the doctor blade is formed between the upper pressing plate 1 and the lower pressing plate 3.
The section of the rotating shaft 5 has a flat side and a convex side.
The rotation of the shaft 5 causes the plane side of the D-shape to face the lower platen 3 to close the gap between the upper platen 1 and the lower platen 3 for holding the doctor blade.
The lower surface of the lower pressing plate 3 is provided with a spring leaf 6, and the spring leaf 6 is used for providing clamping force.
The rotating shaft 5 is provided with a handle 7 along the axial direction, and the handle 7 drives the rotating shaft 5 to rotate, so that the side, facing the lower pressing plate 3, of the rotating shaft 5 is switched between the plane side and the bulge side.
As shown in fig. 2(b), the upper platen 1 has an L-shaped cross section.
Overlook under the visual angle, the structure of holding down plate 3 is shown as fig. 3(a), and 3 edges of holding down plate are equipped with locking hole 31, and locking hole 31 is including the bar hole 311 and the circular port 312 that link together, and the diameter of circular port 312 is not less than the width of bar hole 311, and the hasp passes bar hole 311 and makes holding down plate 3 connect on blade holder 4, and the diameter of hasp is not more than the diameter of circular port 312 and is not less than the width of bar hole 311.
In this embodiment, the lock catch is a bolt, and the bolt passes through the strip-shaped hole 311 to connect the lower press plate 3 to the tool apron 4; the diameter of bolt is not more than the diameter of circular port 312 and is not less than the width of bar hole 311, be for when the bolt is rotatory with blade holder 4 separation, can slide to circular port 312 along bar hole 311 and can not drop from circular port 312, and just also realized the unblock between blade holder 4 and the lower pressure plate 3 when bolt and blade holder 4 separation, when making the protruding one side of D type pivot 5 towards lower pressure plate 3, can make the clearance that holds the doctor blade with lever principle's mode between upper pressure plate 1 and the lower pressure plate 3.
After the doctor blade is installed between top board 1 and the holding down plate 3 and is adjusted length and finish, utilize handle 7 to drive 5 antiport of pivot for 5 plane one side of D type pivot is towards holding down plate 3, realizes that top board 1 and holding down plate 3 press from both sides tight doctor blade, slides the hasp back bar downthehole the wrong income blade holder 4 simultaneously, thereby locks holding down plate 3 and blade holder 4, accomplishes the change of doctor blade.
The structure of the underlay sheet 2 is shown in figure 4 from a top view.
The quick-mounting ink scraping knife device for intaglio press includes main operation portion including upper pressure plate, lower pressure plate, handle and lock catch. When the D-shaped shaft rotates, when one side of the protrusion rotates to the lower pressing plate, one side of the lower pressing plate is ejected out for a certain distance, the other side of the lower pressing plate is separated from the upper pressing plate to form a gap, the spring piece 6 is compressed to store elastic potential energy during separation, the gap formed between the upper pressing plate and the lower pressing plate is used for inserting the knife lining plate and the ink scraping knife by utilizing a 'lever principle', and then the locking and loosening effects of the lock catch are matched (locking and unlocking between the lower pressing plate and the knife holder are realized, the gap can be formed only after the lower pressing plate is unlocked, the plane of the D-shaped shaft faces the lower pressing plate during locking, the D-shaped shaft cannot rotate at the moment), and the ink scraping knife is detached and installed.
Make the punch blade that the punch blade is pressed from both sides tightly to punch blade or mention the handle and make the punch blade form the space and be convenient for extract the punch blade through pushing down the handle, replace original device make a round trip to rotate the screw and press from both sides tightly or extract the punch blade, can not only save time, can also improve the efficiency of changing the punch blade.
The device adopts aviation aluminium material, and three-dimensional angle is adjustable, pneumatic control, and the scraping plate is clean. The tool holder can be quickly replaced, and the parallelism is 100 percent. According to the test, the range of the scraper moving is less than or equal to +/-5 mm. Each group with the reciprocating movement amount of +/-5 mm of the scraper is driven by an independent motor, so that the use requirement of the ink scraping knife is met.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
