Description

Technical Field

[0001] The utility model relates to the technical field of plate-making machines, in particular to a vertical plate-making machine. Background Technique

[0002] In the printing industry, as a key device in the traditional plate-making field, the plate-making machine plays a crucial role. The plate-making machine transfers images or texts from the original manuscript to the printing plate through exposure technology, and its working principle involves multiple fields such as optics and electronics. However, most of the plate-making machines widely used in the current market adopt the design of single-sided light source plate-making. To a certain extent, this design limits its application scope and efficiency. During the exposure process of the single-sided light source plate-making machine, the light source can only irradiate the photosensitive plate material from a single direction, resulting in relatively low exposure efficiency and it is difficult to ensure the exposure uniformity of the entire plate surface. Especially when processing printing plates with large areas or high-precision requirements, this limitation is particularly obvious.

[0003] In view of the limitations of the single-sided light source plate-making machine, double-sided light source plate-making machines have emerged. In order to achieve uniform irradiation of the double-sided light source, the plate-making machine needs to design a more complex internal structure. Since the double-sided light source plate-making machine needs to accommodate more light sources and optical components, its overall volume is often larger than that of the single-sided light source plate-making machine. This not only occupies more production space but also increases the difficulty of transportation and installation.

[0004] Therefore, in order to solve the defects of the existing technology, there is an urgent need for a new type of double-sided light source plate-making machine with a more compact structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a vertical plate-making machine to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A vertical plate-making machine includes a machine table. Above the machine table, there is a plate-making box. A power switch is installed on the right side wall of the machine table. A control box is installed on the right side wall of the plate-making box. The front end of the plate-making box is open, and a front box cover is hinged at the bottom of the opening. On both side walls of the plate-making box, there is a box cover driving telescopic rod hinged. The end of the box cover driving telescopic rod is hinged on the front box cover. On the surface of the front box cover facing the plate-making box, there is a front ultraviolet lamp group installed. On the rear inner wall of the plate-making box, there is a rear ultraviolet lamp group installed. On the front box cover, there is also a plate loading rack installed. The plate loading rack is located above the front ultraviolet lamp group. The plate loading rack includes an upper frame and a lower frame. The lower frame is fixedly installed on the front box cover, and the upper frame is detachably installed above the lower frame.

[0008] Further, a pair of hinge seats are fixedly connected to the front cover, and a pair of parallel frame driving telescopic rods are hinged to each hinge seat, and the ends of the frame driving telescopic rods are hinged to the outer side wall of the upper frame.

[0009] Further, a touch switch is fixedly installed at the top of the port of the printing plate exposure box, a touch head is installed on the front cover, and the front ultraviolet lamp group and the rear ultraviolet lamp group remain powered on when the touch head contacts the touch switch.

[0010] Further, a pressing foot is installed at each of the four corners of the upper frame and the lower frame, and the pressing foot includes a mounting base and a contact rubber pad.

[0011] Further, universal wheels with brakes are installed at the bottom of the machine table.

[0012] Further, the frames of the machine table, the printing plate exposure box and the plate loading rack are all made of standard industrial aluminum profiles.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the double-sided light source design, the present utility model realizes uniform exposure of the photosensitive plate material from both the front and the back directions, significantly improving the exposure efficiency and uniformity; compared with the traditional double-sided light source printing plate exposure machine, the vertical structure is more compact, reducing the floor area and facilitating flexible deployment in a limited production space.

[0015] 2. In the present utility model, the upper frame is controlled to open and close by two pairs of parallel frame driving telescopic rods. During the opening and closing process, the upper frame remains parallel, and the damage to the photosensitive plate is small when the upper frame is fully closed. The contact rubber pad of the pressing foot ensures that the plate material does not move during the exposure process and at the same time protects the surface of the plate material from damage.

[0016] 3. In the present utility model, when the touch head contacts the touch switch at the top of the port of the printing plate exposure box, the trigger circuit is closed, avoiding the abnormal opening of the ultraviolet lamp when the control box fails and causing harm to others.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1: Please refer to Figures 1 to 5 , a vertical plate exposure machine, including a machine platform 1, a plate exposure box 3 is arranged above the machine platform 1, a power switch 2 is installed on the right side wall of the machine platform 1, a control box 4 is installed on the right side wall of the plate exposure box 3, the front end of the plate exposure box 3 is open, and a front box cover 5 is hinged at the bottom of the opening. A box cover driving telescopic rod 6 is hinged on both side walls of the plate exposure box 3, and the end of the box cover driving telescopic rod 6 is hinged on the front box cover 5. A front ultraviolet lamp group 8 is installed on the surface of the front box cover 5 facing the plate exposure box 3, a rear ultraviolet lamp group 7 is installed on the rear inner wall of the plate exposure box 3, and a plate mounting rack 11 is also installed on the front box cover 5. The plate mounting rack 11 is located above the front ultraviolet lamp group 8. The plate mounting rack 11 includes an upper frame 12 and a lower frame 13. The lower frame 13 is fixedly installed on the front box cover 5, and the upper frame 12 is openably installed above the lower frame 13.

[0025] A pair of hinge seats 14 are fixedly connected to the front box cover 5, and a pair of parallel frame closing driving telescopic rods 15 are hinged on each hinge seat 14. The end of the frame closing driving telescopic rod 15 is hinged on the outer side wall of the upper frame 12.

[0026] A touch switch 10 is fixedly installed at the top of the port of the plate exposure box 3, a touch head 9 is installed on the front box cover 5, and when the touch head 9 contacts the touch switch 10, the front ultraviolet lamp group 8 and the rear ultraviolet lamp group 7 remain powered on.

[0027] A pressing foot 16 is installed at each of the four corners of the upper frame 12 and the lower frame 13. The pressing foot 16 includes an installation base 18 and a contact rubber pad 17.

[0028] Universal wheels 19 with brakes are installed at the bottom of the machine platform 1.

[0029] The frames of the machine table 1, the printing plate exposing box 3, and the plate mounting rack 11 are all made of standard industrial aluminum profiles.

[0030] The working principle of this embodiment:

[0031] During operation, first place the photosensitive plate to be exposed on the plate mounting rack 11, and firmly clamp the plate through the cooperation of the upper frame 12 and the lower frame 13. The contact rubber pad 17 of the pressure foot 16 ensures that the plate does not move during the exposure process, and at the same time protects the surface of the plate from damage. After the plate is loaded, the telescopic rod 6 driven by the box cover will assist the front box cover 5 to close smoothly. As the front box cover 5 closes, the front ultraviolet lamp group 8 and the rear ultraviolet lamp group 7 are simultaneously powered on to start the exposure process. The double-sided light works simultaneously, uniformly exposing the photosensitive plate from the front and back directions, effectively solving the problems of uneven exposure and low efficiency of traditional single-sided light source printing plate exposing machines, and is particularly suitable for the production of printing plates with large areas or high precision requirements. After the exposure time reaches the preset value, the ultraviolet lamp group automatically cuts off the power. The operator can open the front box cover 5 and take out the exposed plate for subsequent processing. The power switch 2 controls the main power switch, and the control box 4 controls the exposure intensity and exposure duration.

[0032] The upper frame 12 is controlled to open and close by two pairs of telescopic rods 15 for frame driving arranged in parallel. During the opening and closing process, the upper frame 12 remains parallel, and when the upper frame 12 is fully closed, the damage to the photosensitive plate is small.

[0033] The touch head 9 contacts the touch switch 10 at the top of the port of the printing plate exposing box 3, triggering the circuit to close, and avoiding the abnormal opening of the ultraviolet lamp when the control box 4 fails, which may cause harm to others.

[0034] The contact rubber pad 17 of the pressure foot 16 ensures that the plate does not move during the exposure process, and at the same time protects the surface of the plate from damage.

[0035] The frames of the machine table 1, the printing plate exposing box 3, and the plate mounting rack 11 are all made of standard industrial aluminum profiles, which are not only structurally strong, but also corrosion-resistant and easy to clean, reducing the maintenance cost.

[0036] The universal wheels 19 with brakes installed at the bottom of the machine table 1 enable the equipment to be easily moved to the required position and stably fixed, facilitating rapid deployment and use in different working environments.

[0037] Through the double-sided light source design in this embodiment, uniform exposure of the photosensitive plate from the front and back directions is achieved, significantly improving the exposure efficiency and uniformity; compared with traditional double-sided light source printing plate exposing machines, the vertical structure is more compact, reducing the floor area and facilitating flexible deployment in limited production spaces.
