Description

Swing arm type impression device of printing machine

Technical Field

The utility model relates to an impression unit on the printing machine, concretely relates to swing arm formula impression device of printing machine.

Background

A printer is a machine that prints text and images. Modern printing presses typically consist of mechanisms for plating, inking, stamping, feeding (including folding), etc. The working principle is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position of the characters and images on the printing plate by manual or printing machine, then it is directly or indirectly transferred on the paper or other printing material (such as textile, metal plate, plastics, leather, wood plate, glass and ceramic) so as to reproduce the same printed matter as the printing plate.

Particularly, in the imprinting process, the press roller and the printing plate are required to be matched, when a printing stock passes through the space between the press roller and the printing plate, enough force pressure is required to print ink on the printing stock, the traditional method is that the press roller and the printing plate are in direct contact, so that the space requirement and the pressure requirement of different printing stocks cannot be met, and meanwhile, a contact point between the press roller and the printing plate cannot obtain stable support to influence the imprinting effect, so that the performance is unstable.

Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide a swing arm type imprinting apparatus for a printing machine with reliable structure and stable performance.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a swing arm formula impression device of printing machine, includes both sides board, compression roller and printing plate, install cylinder and swing arm on the curb plate, the rotatable installation of tail end of cylinder be in the curb plate on, the swing arm be "L" shape, rotatable the installation in its middle part through a pivot on the curb plate, the tailpiece of the piston rod portion of cylinder with the one end of swing arm is articulated, the detachable installation of compression roller the swing arm is close to the one end of cylinder, the compression roller be in under the promotion of cylinder with the printing plate contacts.

The side plate is inserted with a support shaft, the middle position of the support shaft is sleeved with a positioning sleeve, the positioning sleeve is connected with the side plate through a bolt, and the end part of the support shaft is rotatably connected with the tail part of the cylinder.

The swing arm is close to the tip of the piston rod of cylinder is equipped with U type groove be equipped with the screw hole that leads to this U type inslot on the swing arm, this threaded hole disposes positioning bolt.

The swing arm keep away from the deflector roll is installed to the other end of the piston rod of cylinder.

The utility model discloses a this kind of structure for the compression roller passes through the cylinder and realizes the contact action with the printing plate, and simultaneously under the restriction of swing arm, the stability that can make the compression roller push down is better, has guaranteed the quality of stock printing, can satisfy the stock needs of different materials and thickness moreover, just so realizes that the structure is reliable, stable performance's technological effect.

The invention is further described with reference to the accompanying drawings and the detailed description.

FIG. 1 is a block diagram of an embodiment of the present invention;

FIG. 2 is a cut-away view A-A of FIG. 1;

FIG. 3 is a cut-away view of C-C of FIG. 1;

fig. 4 is an enlarged view of D in fig. 1.

Detailed Description

The present invention will be specifically described below by way of examples.

As shown in fig. 1-4, this embodiment discloses a swing arm 5 type impression device of printing machine, including two side plates 1, compression roller 2 and printing plate 3 set up between two side plates, install cylinder 4 and swing arm 5 on side plate 1, the both ends of compression roller rotate respectively and connect on swing arm 5, the tail end of cylinder 4 is rotatable to be installed on side plate 1, swing arm 5 is "L" shape, its middle part is rotatable through a pivot 6 to be installed on side plate 1, the tailpiece of the piston rod portion of cylinder 4 is articulated with the one end of swing arm 5, compression roller 2 is detachable to be installed in the one end that swing arm 5 is close to cylinder 4, compression roller 2 contacts with printing plate 3 under the promotion of cylinder 4.

A supporting shaft 7 is inserted into the side plate 1 in a splicing mode, a positioning sleeve 8 is sleeved in the middle of the supporting shaft 7, the positioning sleeve 8 is connected with the side plate 1 through a bolt, and the end portion of the supporting shaft 7 is rotatably connected with the tail portion of the air cylinder 4. The rotary connection of the cylinder 4 can be more reliable through the structure, and the reliability of the structure can be improved.

The end portion of the swing arm 5 close to the piston rod of the air cylinder 4 is provided with a U-shaped groove 51, the swing arm 5 is provided with a threaded hole 52 leading to the interior of the U-shaped groove 51, a positioning bolt is arranged in the threaded hole 52, and after shaft ends on two sides of the compression roller 2 are clamped into the U-shaped groove 51, the positioning bolt is screwed in, so that the end portion of the positioning bolt enters the U-shaped groove 51, and the shaft ends of the compression roller 2 are limited in the U-shaped groove 51. The press roller 2 is detachably connected on the swing arm 5, so that the installation is more convenient,

the other end of the swing arm 5, which is far away from the piston rod of the cylinder 4, is provided with a guide roller 9. The guide roller 9 can ensure that the displacement angle of the printing stock is more reasonable and reliable, and the impression effect of the printing stock is improved.

Adopt above-mentioned technical scheme for compression roller 2 passes through cylinder 4 and realizes the contact action with printing plate 3, and under the restriction of swing arm 5, the stability that can make compression roller 2 push down is better simultaneously, has guaranteed the quality of stock printing, can satisfy the stock needs of different materials and thickness moreover, just so realizes the technological effect that the structure is reliable, stable performance.
