[0002] The clutch pressure structure refers to the structure for controlling the clutching between the printing head and the rubber roller and for completing the ink transfer to the printing medium. The existing printing machines mostly adopt the eccentric sleeve and gear cooperation to perform the printing clutching. This structure has high processing requirements for the inner diameter of the wallboard roller hole and the outer diameter of the eccentric sleeve. In order to ensure the gap, even the processing needs to be matched, and the process requirement is complex.

[0003] Moreover, the eccentric distance of the eccentric sleeve is usually small due to the structural problem, and the space is small during the paper feeding and carbon tape feeding process, and the operation is very inconvenient. UTILITY MODEL CONTENTS

[0005] The technical scheme for solving the above technical problem is as follows: a printing machine clutch pressure structure comprises a cylinder and a rubber roller support block, the telescopic end of the cylinder is hingedly connected to one side of the rubber roller support block, a printing head rubber roller is arranged on the side of the rubber roller support block away from the cylinder, at least one connecting rod is hingedly connected to the other side of the rubber roller support block, the end of the connecting rod away from the rubber roller support block is rotationally connected to a first rotating shaft, and the connecting rod rotates around the first rotating shaft.

[0006] When the cylinder is pushed out to the working position, the axis of the cylinder output shaft intersects and is perpendicular to the axis of the printing head rubber roller.

[0007] The utility model has the beneficial effects that: the printing head rubber roller is pushed by the cylinder to perform the printing work, and the cylinder is perpendicular to the printing head rubber roller when being pushed out, so that the force bearing is good, and no part bears the torque; moreover, the cylinder has a large retraction space, which is convenient for the replacement of paper and carbon tape and the cleaning work of the printing head and the printing head rubber roller.

[0008] On the basis of the above technical scheme, the utility model can also be improved as follows.

[0009] Further, a waiting position support is arranged on the side of the rubber roller support block close to the cylinder, the waiting position support is rotationally connected to a second rotating shaft, the waiting position support rotates around the second rotating shaft, and the waiting position support comprises a limiting part and a supporting part.

[0010] When the cylinder is retracted to the waiting position, the limiting part abuts against the rubber roller support block.

[0011] When the cylinder continues to retract to the operating position, the supporting part abuts against the rubber roller supporting block.

[0012] The waiting position support can limit and support the rubber roller supporting block, and prevent the rubber roller supporting block from exceeding the working position.

[0013] Further, the waiting position support further comprises a driving part.

[0014] The driving part can drive the waiting position support.

[0015] Further, a driving cylinder is arranged on one side of the waiting position support, and an extension end of the driving cylinder is connected with the driving part in power connection for driving the waiting position support to rotate.

[0017] Further, a driving support is arranged below the waiting position support, the driving support is hinged with the driving part, and the extension end of the driving cylinder is hinged with the driving support.

[0018] The driving support can be provided with a plurality of waiting position supports, and the power utilization rate of the driving cylinder is maximized.

[0019] Further, an end surface of the limiting part is arc-shaped.

[0020] The arc-shaped end surface can facilitate the rotation of the waiting position support and prevent the waiting position support from being stuck.

[0021] Further, the number of the connecting rods is two and the connecting rods are parallel to each other.

[0022] The two connecting rods form a parallelogram, and the stress structure and stability are better.

[0023] Further, a hinge seat is rotatably connected to one end of the cylinder away from the rubber roller supporting block, and the cylinder rotates around the hinge seat.

[0024] The mounting seat of the cylinder is hinged, and the cylinder is prevented from being stuck with the connecting rod during extension and retraction.

[0025] Further, a printing head of the printing machine is arranged on one side of the printing head rubber roller.

[0026] When the cylinder is ejected to the working position, the printing head abuts against the printing head rubber roller.

[0027] The beneficial effect of the further scheme is that the printing head contacts the printing head rubber roller to perform printing work, and the printing head rubber roller is located directly below the printing head when being ejected, thereby ensuring good force.

[0028] The utility model also provides a printing machine, including the printing machine clutch pressure structure of above.

[0029] The beneficial effect of the further scheme is that the clutch pressure structure has a larger operation space, facilitates replacement of materials and cleaning, and is convenient to use. BRIEF DESCRIPTION OF DRAWINGS
