Description

Technical Field

[0001] This utility model belongs to the field of printing press technology, and in particular relates to a printing press with a guiding structure. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms such as plate mounting, inking, printing, and paper feeding. Its working principle is as follows: First, the text and images to be printed are made into a printing plate and mounted on the printing press. Then, ink is applied to the areas on the printing plate with text and images by hand or by the printing press. The ink is then transferred directly or indirectly to paper or other printing substrates, thereby reproducing printed materials identical to the printing plate.

[0003] Existing printing presses are prone to roll misalignment during operation, resulting in poor printing quality. Therefore, we propose a printing press with a guiding structure. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a printing press with a guiding structure to enable guiding operations on printing rolls.

[0005] In view of this, the present invention provides a printing machine with a guiding structure, including a printing machine body, a feeding frame fixedly connected to the outer wall of the printing machine body, a connecting roller provided on the inner wall of the feeding frame, a guide roller provided on one side of the connecting roller, an adjusting frame fixedly connected to the bottom end of the feeding frame, a screw bearing connected to the inner wall of the adjusting frame, a handwheel fixedly connected to one end of the screw, a threaded slider threadedly connected to the outer wall of the screw, a limit block fixedly connected to the top end of the threaded slider, a limit rod fixedly connected to the inner wall of the limit block and the inner wall of the limit block, a pointer fixedly connected to the outer wall of the limit block, a scale fixedly connected to the lower part of the pointer on the outer wall of the adjusting frame, a connecting ring fixedly connected to the top end of the limit block, a connecting seat sleeved on the outer wall of the guide roller through the inner wall of the connecting ring, and a guide plate fixedly connected to the outer wall of the connecting seat.

[0006] Based on the above structure, the sliding of the threaded slider drives the limiting block to slide along the outer wall of the limiting rod, and slides the pointer on the outer wall of the limiting block to the predetermined position of the scale. At the same time, the sliding of the limiting block drives the connecting ring to slide synchronously, the sliding of the connecting ring drives the connecting seat to slide along the outer wall of the guide roller, and the sliding of the connecting seat drives the guide plate to guide the printing roll, so as to avoid the printing roll from deviating and resulting in poor printing effect.

[0007] Preferably, two sets of connecting rollers are provided, and the two sets of connecting rollers are symmetrical about the central axis of the guide roller. In this embodiment, it is convenient for the active roller inside the printing press to work to pass the printing roll through the two sets of connecting rollers and guide rollers to realize the feeding operation of the printing roll.

[0008] Preferably, the guide roller and the two sets of connecting rollers are arranged in an inverted "V" shape. In this embodiment, by setting the guide roller and the two sets of connecting rollers in an inverted "V" shape, it is beneficial for the printing roll to fit tightly with the guide roller, and to avoid wrinkles in the printing roll during the guiding process.

[0009] Preferably, the limiting block forms a sliding structure with the limiting rod through a screw and a threaded slider. In this embodiment, the rotation of the handwheel drives the threaded slider to slide through the screw, and the sliding of the threaded slider drives the limiting block to slide along the outer wall of the limiting rod, so as to slide the pointer on the outer wall of the limiting block to the predetermined position of the scale.

[0010] Preferably, the guide roller and the limiting rod are parallel. In this embodiment, it is convenient for the limiting block to slide and drive the connecting ring to slide synchronously, and the sliding of the connecting ring to drive the connecting seat to slide along the outer wall of the guide roller.

[0011] Preferably, the connecting seat and the guide plate are arranged in a stepped manner. In this embodiment, the connecting seat slides to drive the guide plate to guide the printing roll.

[0012] Preferably, the guide discs are provided in two sets. In this embodiment, by providing two sets of guide discs, it is convenient to guide both sides of the printing roll material together, and avoid the guide discs sliding too far, which would cause wrinkles in the printing roll material.

[0013] The beneficial effects of this utility model are:

[0014] 1. This printing press with a guiding structure, by setting up guide rollers distributed in an inverted "V" shape and two sets of connecting rollers, facilitates a tight fit between the printing roll and the guide rollers, avoiding wrinkles in the printing roll during guidance. By setting up two sets of guide discs, it is convenient to jointly guide both sides of the printing roll, avoiding excessive sliding distance of the guide discs, which would cause wrinkles in the printing roll.

[0015] 2. This printing press with a guide structure, by setting a connecting ring, allows the threaded slider to slide along the outer wall of the limiting block, moving the pointer on the outer wall of the limiting block to a predetermined position on the scale. At the same time, the sliding of the limiting block causes the connecting ring to slide synchronously, which in turn causes the connecting seat to slide along the outer wall of the guide roller. The sliding of the connecting seat then causes the guide disc to guide the printing roll, preventing the printing roll from shifting and resulting in poor printing quality.

A connecting seat 14, which is sleeved on the outer wall of the guide roller 4, passes through the inner wall of the connecting ring 13. A guide plate 15 is fixedly connected to the outer wall of the connecting seat 14.

[0025] Based on the above structure, the threaded slider 8 slides and drives the limiting block 9 to slide along the outer wall of the limiting rod 10, sliding the pointer 11 on the outer wall of the limiting block 9 to the predetermined position of the scale 12. At the same time, the limiting block 9 slides and drives the connecting ring 13 to slide synchronously. The connecting ring 13 slides and drives the connecting seat 14 to slide along the outer wall of the guide roller 4. The connecting seat 14 slides and drives the guide disk 15 to guide the printing roll, avoiding the printing roll from shifting and resulting in poor printing effect.

[0026] In one embodiment, two sets of connecting rollers 3 are provided, and the two sets of connecting rollers 3 are symmetrical about the central axis of the guide roller 4.

[0027] In this embodiment, the active roller inside the printing press body 1 facilitates the operation of feeding the printing roll through two sets of connecting rollers 3 and guide rollers 4.

[0029] In this embodiment, by setting the guide rollers 4 and two sets of connecting rollers 3 in an inverted "V" shape, it is beneficial for the printing roll to fit tightly with the guide rollers 4, thus avoiding wrinkles in the printing roll during the guiding process.

[0030] In one embodiment, the limiting block 9 forms a sliding structure with the limiting rod 10 through the screw 6 and the threaded slider 8.

[0031] In this embodiment, the rotation of the handwheel 7 drives the threaded slider 8 to slide via the screw 6. The sliding of the threaded slider 8 causes the limiting block 9 to slide along the outer wall of the limiting rod 10, so that the pointer 11 on the outer wall of the limiting block 9 can be slid to the predetermined position of the scale 12.

[0032] In one embodiment, the guide roller 4 and the limiting rod 10 are parallel.

[0033] In this embodiment, the limiting block 9 slides to drive the connecting ring 13 to slide synchronously, and the sliding of the connecting ring 13 drives the connecting seat 14 to slide along the outer wall of the guide roller 4.
