Description

Technical Field

[0001] This utility model relates to the field of vacuum printing maintenance technology, and more specifically, to a maintenance door for vacuum printing. Background Technology

[0002] Existing automatic vacuum plugging machines have an integrated design for the top cover of both the infeed and discharge vacuum chambers. When maintenance is required, the top cover must be completely disassembled, moved to one side, or one end lifted to expose the interior for easy access. Disassembling the entire top cover requires forklifts or cranes, which is inconvenient in a workshop. Moving the top cover to one side requires sufficient space for movement, resulting in a large overall layout requirement. Lifting one end of the top cover limits the opening and closing space, hindering maintenance. Therefore, we propose an improved access door for vacuum printing. Utility Model Content

The sealing cavity plate is also provided with two inspection door structures, which are arranged in opposite directions. The two inspection door structures are used to block the two inspection ports respectively. Each inspection door structure includes a driving part provided on the sealing cavity plate, and the driving part is connected to a sealing cover plate. The driving part is used to drive the sealing cover plate to move horizontally and lift vertically to realize the opening and closing of the sealing cover plate. When the sealing cover plate is open, it is located on the side of the inspection port.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-4 A maintenance door for vacuum printing includes a sealing cavity plate 1, with two maintenance ports 101 in the middle area of ​​the sealing cavity plate 1. The sealing cavity plate 1 also has two maintenance door structures 2, which are designed to open in opposite directions. Each maintenance door structure 2 is used to block one of the two maintenance ports 101. Each maintenance door structure 2 includes a drive unit mounted on the sealing cavity plate 1, and the drive unit is connected to a sealing cover plate 206. The drive unit drives the sealing cover plate 206 to move horizontally and vertically, thereby opening and closing the sealing cover plate 206. When open, the sealing cover plate 206 is located on the side of the maintenance port 101. The two maintenance door structures 2 are designed to open in opposite directions. When opened, the two sealing cover plates 206 move to opposite sides and separate, occupying space on both sides of the maintenance port 101 without additional space outside the machine, facilitating maintenance. Furthermore, the drive unit can drive the sealing cover plate 206 to open and close without the need for external forklifts or cranes.

[0020] Furthermore, the drive unit includes a horizontal drive member disposed on the sealing cavity plate 1, a lifting member connected to the horizontal drive member, and the lifting member being connected to the sealing cover plate 206.

[0021] Furthermore, the horizontal drive component includes two mounting brackets 207 mounted on the top of the sealing chamber plate 1. A horizontal cylinder 208 is connected between the two mounting brackets 207. The piston rod of the horizontal cylinder 208 is connected to a connecting plate 209, and the connecting plate 209 is connected to the lifting component. The mounting brackets 207, the horizontal cylinder 208, and the sealing chamber plate 1 are connected by bolts. A through hole is installed on the connecting plate 209. The front end of the piston rod of the horizontal cylinder 208 passes through the through hole and is fixed by a nut to realize the connection between the piston rod of the horizontal cylinder 208 and the connecting plate 209.

[0022] Furthermore, the horizontal drive component also includes a support frame 204, with support plates 203 connected to both sides of the bottom of the support frame 204. The support plate 203 near the horizontal cylinder 208 is connected to the connecting plate 209, and the support plate 203, the connecting plate 209, and the support frame 204 are all connected by bolts.

[0023] Furthermore, the lifting component includes several lifting cylinders 205 mounted on the support frame 204. The lifting cylinders 205 are used to drive the sealing cover plate 206 to rise and fall. The lifting cylinders 205 are mounted on the support frame 204 by bolts. The piston rod of the lifting cylinder 205 is threadedly connected to an I-shaped rod 212. A connecting seat 211 is installed on the top of the sealing cover plate 206. The connecting seat 211 is provided with a slot for inserting into the I-shaped rod 212. The connecting seat 211 and the sealing cover plate 206 are connected by bolts. The connection between the lifting cylinder 205 and the sealing cover plate 206 can be realized by engaging the I-shaped rod 212 with the slot on the connecting seat 211.

[0024] Furthermore, a limiting rod 210 is installed on the top of the sealing cover 206. The top end of the limiting rod 210 passes through the support frame 204. The limiting rod 210 is installed on the top of the sealing cover 206 by bolts. A linear bearing is provided at the connection between the limiting rod 210 and the support frame 204. The limiting rod 210 can cooperate with the support frame 204 to limit the sealing cover 206, making the sealing cover 206 more stable when it is raised and lowered.

[0025] Furthermore, a limiting component is provided between the support plate 203 and the sealing cavity plate 1; the limiting component includes a slide rail 201 installed on the sealing cavity plate 1, a slide seat 202 connected to the slide rail 201, and the slide seat 202 connected to the support plate 203. The slide rail 201 is installed on the sealing cavity plate 1 by bolts, and the slide seat 202 is connected to the support plate 203 by bolts. The slide seat 202 and the slide rail 201 cooperate with each other to limit the support plate 203, making the support plate 203 more stable when it moves.

[0026] Furthermore, a sealing element is provided on the side of the sealing cover plate 206 near the sealing cavity plate 1. The sealing element can be a rubber sealing gasket or a sealing ring. The sealing element is fixed by adhesive. The setting of the sealing element can improve the sealing effect of the sealing cover plate 206 on the inspection port 101 when it is closed.

[0027] The usage process of the inspection door for vacuum printing provided by this utility model is as follows: When the door is closed, the horizontal cylinder 208 drives the connecting plate 209 to move towards the access port 101. The connecting plate 209, through the support plate 203, drives the support frame 204 to move towards the access port 101, causing the sealing cover 206 to move to the access port 101. Then, the lifting cylinder 205, through the connecting seat 211 and the I-shaped rod 212, drives the sealing cover 206 to move towards the sealing cavity plate 1, so that the sealing cover 206 covers the access port 101, i.e. Figure 4 As shown; When the door is opened, the lifting cylinder 205 first drives the sealing cover 206 away from the access port 101, and then the horizontal cylinder 208 drives the connecting plate 209 to move away from the access port 101. The connecting plate 209 drives the support frame 204 to move through the support plate 203, so that the sealing cover 206 moves away from the access port 101, i.e. Figure 1 As shown.
