[0032] Example 1

[0033] The present embodiment provides a ventilation-type green printing platemaking device, comprising a box body 1, a feed port and a discharge port arranged at both ends of the box body 1 for conveying a chain a and a substrate b to enter and exit, a fixed plate 2 arranged in the box body 1 and located at the upper end of the conveying chain a, an irradiation lamp 3 arranged on the surface of the fixed plate 2 on one side close to the conveying chain a, an air outlet 4 arranged on the box body 1 and located at the upper end of the fixed plate 2, and an exhaust fan 5 connected to the air outlet 4; the two ends of the fixed plate 2 along the direction perpendicular to the conveying chain a are respectively connected to the inner walls on both sides of the box body 1, and two air ducts c are formed between the two ends of the fixed plate 2 along the direction parallel to the conveying chain a and the inner walls on both sides of the box body 1.

[0034] The working principle of the platemaking equipment provided in this embodiment includes: placing the printing substrate b on the conveyor chain a and entering the box 1 under the operation of the conveyor chain a. When the printing substrate b is located at the lower end of the irradiation lamp 3, the irradiation lamp 3 works to expose the printing substrate b. At this time, the harmful gas will evaporate faster under the heating condition. The suction force generated by the exhaust fan 5 will suck the harmful gas from the space below the irradiation lamp 3 into the air duct c, and finally be discharged through the exhaust fan 5.

[0035] It is worth noting that, in order to improve the guiding effect of harmful gases, an inclined plate is provided on the upper inner wall of the box 1. The chain a and the structure of driving the chain a to drive the substrate b to move are well known in the art, so this embodiment will not be repeated.

[0036] Compared with the prior art, the platemaking equipment provided in this embodiment has the advantages that it can replace manual loading by transmission chain transmission loading, and can continuously process continuously loaded printing materials, which not only ensures the stability of the processing effect, but also has the advantage of high work efficiency.

[0037] Example 2

[0038] This embodiment optimizes the structure based on the embodiment 1, specifically including:

[0039] In this embodiment, the platemaking equipment includes a first blowing structure 6 arranged on the box body 1 near the feed port, and a second blowing structure 7 arranged on the box body 1 near the discharge port; the air outlets of the first blowing structure 6 and the second blowing structure 7 are respectively facing the two air ducts c.

[0040] As a further preference of this embodiment, the first blowing structure 6 and the second blowing structure 7 have the same structure, and the first blowing structure 6 includes an air inlet pipe 601, an air supply pipe 602 connected to the air inlet pipe 601, an air outlet pipe 603 connected to the air supply pipe 602, and a strip air outlet 604 arranged on the air outlet pipe 603; the length of the strip air outlet 604 is greater than or equal to the length of the feed port.

[0041] As a further preference of this embodiment, it also includes an air supply structure, which includes a main pipe 801, two delivery branch pipes 802 arranged on the main pipe 801 and respectively connected to the first blowing structure 6 and the second blowing structure 7, and a fan 803 for delivering gas to the main pipe 801.

[0042] The working principle of this embodiment includes: air is transported to the first blowing structure 6 and the second blowing structure 7 through the air supply structure, and the two blowing structures blow air toward the two air ducts c respectively. Due to the special shape design of the strip air outlet 604, it can be ensured that the output air can cover the feed port and the discharge port, so that the generated harmful gas cannot be discharged out of the box through the feed port and the discharge port, thereby ensuring the safety of the working environment; at the same time, it can also supplement the kinetic energy of blowing the harmful gas to the exhaust fan 5, thereby ensuring the discharge efficiency of the harmful gas.

[0043] Example 3

[0044] This embodiment optimizes the air supply structure based on the embodiment 2, specifically including:

[0045] The air supply structure includes a filter box 804 connected to the air inlet of the fan 803 , a connecting pipe 805 arranged on the filter box 804 and connected to the air outlet of the exhaust fan 5 , and a filter 806 arranged in the filter box 804 .

[0046] As a further preferred embodiment of the present invention, the filter 806 includes a primary filter plate, a secondary filter plate and a tertiary filter plate in sequence along the air delivery direction. The primary filter plate, the secondary filter plate and the tertiary filter plate can be selected from commonly used activated carbon filters, sub-glass fiber membranes, etc.

[0047] The advantage of such arrangement of this embodiment is that the harmful gas extracted by the exhaust fan 5 can be processed in time, and the harmless gas after processing can be directly input into the first blowing structure 6 and the second blowing structure 7 for use, which has the advantage of recycling.

[0048] Example 4

[0049] This embodiment optimizes the structure based on Embodiment 2 and Embodiment 3, as follows:

[0050] The air delivery pipe 602 includes a telescopic pipe body 602a connected to the air pipe 601 and a supporting pipe body 602b connected to the air outlet pipe 603. The telescopic pipe body 602a may be a corrugated pipe, which may be extended as the supporting pipe body 602b is pulled.

[0051] The first blowing structure 6 also includes a fixed sleeve 605 arranged on the supporting tube body 602b, a fixed frame 606 arranged in the box body 1 and rotatably connected to the fixed sleeve 605, an extension rod 607 vertically arranged on the supporting tube body 602b, a vertical rod 608 arranged on the conveying chain a and used to push the extension rod 607, and a protrusion 609 arranged on the end of the extension rod 607 away from the supporting tube body 602b.

[0052] The vertical rod 608 includes a rod body 608a inserted on the conveying chain a, and a limiting plate 608b arranged on the rod body 608a.

[0053] The working principle of this embodiment includes: after placing the printing material on the conveyor chain, vertical rods are placed at the front and rear ends of the printing material respectively, and the vertical rods are inserted into the conveyor chain for fixing. When the conveyor chain drives the vertical rod to move in the box, the vertical rod contacts the extension rod and pushes the extension rod to rotate, and the extension rod drives the support tube body to rotate with the connection point where the fixed sleeve and the fixed frame are rotatably connected as the center of the circle, and the strip air outlet rotates from facing the side wall of the box to facing the air duct, thereby achieving the effect of blocking the feed inlet and the discharge port.

[0054] The advantage of such an arrangement is that it can ensure that the printing substrate will not be blown by the first blowing structure and the second blowing structure all the time when the printing substrate has not reached the preset position, thereby affecting the plate making effect on the printing substrate.

[0055] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
