Abstract
Description
Technical Field
[0001] This utility model relates to the field of wide-format paper inkjet printing technology, and in particular to a conveying mechanism for wide-format paper inkjet printing. Background Technology
[0002] Wide-format inkjet printing is a technology that uses a wide-format inkjet printer to print images on wide-format paper. This technology can handle paper that is usually more than 1 meter wide and is suitable for large-size printing needs such as advertising, posters, exhibition boards, and decorative paintings. Wide-format inkjet printers are usually equipped with high-resolution printheads and advanced printing technology, which can achieve high-quality and high-precision image output.
[0003] Wide-format inkjet printers are mainly used for printing on wide-format paper. When using existing wide-format inkjet printers, the printing material needs to be loaded into the paper feeding system of the printer. The paper feeding system mainly consists of a roll. When in use, the roll is inserted into the surface of the roll, one end of the roll is pulled out and passed through the inside of the printer, and then the drive component on the other side of the printer drives the roll to be conveyed. At the same time, the internal printhead sprays back and forth, thereby realizing the printing process on wide-format paper.
[0004] When using existing inkjet printers, the material roll needs to be inserted into the spool. However, the existing spool structure makes the loading process cumbersome, making it difficult to easily remove the spool for loading, which affects loading efficiency and makes the printer inconvenient to use.

[0016] (III) Beneficial Effects
[0017] This utility model provides a conveying mechanism for wide-format paper inkjet printing. It has the following beneficial effects:

Detailed Implementation
[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0029] Example 1
[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This is the first embodiment of the present invention. This embodiment provides a conveying mechanism for wide-format paper inkjet printing, including a machine housing 1. Two fixed seats 2 are provided on one side of the machine housing 1. A feeding assembly 3 is provided between the two fixed seats 2. A pressing assembly 4 is provided between the two fixed seats 2. The feeding assembly 3 includes a rotating plate 303 hinged to the outer surface of the fixed seat 2. A roller 306 is movably connected to the inside of the rotating plate 303 through a bearing. A rotating rod 405 is hinged to the outer surface of the rotating plate 303. A sliding block 304 is hinged to the bottom end of the rotating rod 405. A locking block 301 is slidably provided on the upper surface of the fixed seat 2. A spring 302 is fixedly connected between the locking block 301 and the fixed seat 2.
[0031] Specifically, the outer surface of the sliding block 304 is provided with a limiting protrusion, and the outer surface of the fixed base 2 is provided with a groove that cooperates with the limiting protrusion. Through the setting of the groove and the limiting protrusion, the sliding block 304 can be restricted inside the groove. When the rotating plate 303 rotates outward, the sliding block 304 can press against the support rod 305 at the bottom of the groove, thereby preventing the rotating plate 303 from tilting outward.
[0032] Specifically, the upper surface of the fixed base 2 is provided with a limiting groove, the locking block 301 slides in the limiting groove, one end of the spring 302 is fixedly connected to the inner wall of the limiting groove, and the top of the rotating plate 303 is provided with a groove that cooperates with the locking block 301. The locking block 301 is restricted inside the limiting groove, thereby preventing the locking block 301 from protruding outward and disengaging from the limiting groove under the action of the spring 302. Through the cooperation of the spring 302 and the locking block 301, the groove on the top of the rotating plate 303 can be engaged to lock the rotating plate 303 and prevent the rotating plate 303 from rotating outward.
[0033] Specifically, the outer surface of the fixed base 2 is provided with an arc-shaped limiting groove that cooperates with the roller 306. When the roller 306 passes through the two rotating plates 303, both ends of the roller 306 can be inserted into the arc-shaped limiting groove as the rotating plates 303 rotate in, so that both ends of the roller 306 abut against the inner wall of the arc-shaped limiting groove inside the fixed base 2, thus preventing the roller 306 from shifting during subsequent rotation and feeding.
[0034] Furthermore, by moving the locking block 301, the compression spring 302 of the locking block 301 retracts into the limiting groove on the upper surface of the fixed base 2, thereby releasing the top of the rotating plate 303 from its limiting position. This causes the rotating plate 303 to rotate outward, driving the support rod 305 to rotate. The sliding block 304 at the bottom of the support rod 305 slides to the bottom of the groove on the outer surface of the fixed base 2, thus supporting the rotating plate 303 through the support rod 305. After the rotating plate 303 rotates outward, the internal... The spool 306 allows the material to be pulled out from either end, placing the roll between the two rotating plates 303. Then, the spool 306 is inserted back into the rotating plates 303, allowing it to pass through the roll and load the material. When the rotating plates 303 are rotated back to the fixed base 2, both ends of the spool 306 are inserted into the arc-shaped limiting groove inside the fixed base 2, causing the two ends of the spool 306 to abut against the inside of the arc-shaped limiting groove, thereby preventing the spool 306 from shifting as the material is fed.
[0035] Example 2
[0036] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The pressing component 4 includes a bidirectional lead screw 401 that is inserted inside the fixed base 2. The outer surface of the bidirectional lead screw 401 is engaged with two threaded sleeves 403. The outer surface of each of the two threaded sleeves 403 is hinged with a rotating rod 405. The bottom end of the rotating rod 405 is hinged with a pressing shaft 402.
[0037] Specifically, both ends of the clamping shaft 402 are fixedly connected to limit blocks 404 via connecting rods. The outer surface of the fixed seat 2 is provided with a limit groove that matches the limit block 404. One end of the bidirectional screw 401 passes through the fixed seat 2 and is fixedly connected to a rotating handle. By setting the limit block 404, the threaded sleeve 403 is prevented from rotating as the bidirectional screw 401 rotates, thus playing a limiting role.
[0038] Furthermore, by rotating the handle, the bidirectional lead screw 401 is rotated. The rotation of the bidirectional lead screw 401 causes the threaded sleeve 403 to move on the outer surface of the bidirectional lead screw 401, thereby causing the rotating rod 405 to rotate and drive the pressing shaft 402 to press the wide paper downward, thus preventing wrinkles from occurring when the wide paper is fed.
[0039] Working principle: When printing on wide-format paper, the locking block 301 is activated, causing the compression spring 302 to retract into the limiting groove on the upper surface of the fixed base 2. This releases the top of the rotating plate 303 from its limiting position, causing it to rotate outward. Simultaneously, the rotating plate 303 rotates, driving the support rod 305 to rotate as well. The sliding block 304 at the bottom of the support rod 305 slides to the bottom of the groove on the outer surface of the fixed base 2, thus supporting the rotating plate 303. After the rotating plate 303 rotates outward, the internal roller 306 is exposed, allowing it to be pulled out from either end. The roll of paper is placed between the two rotating plates 303, and then the roller 306 is reinserted into the rotating plate 303, allowing it to pass through the roll of paper and reach the position of the other rotating plate 303, thus completing the roll printing. The material is loaded, and then the rotating plate 303 is rotated back into the fixed base 2. When the rotating plate 303 is reset, it drives the two ends of the roll 306 to insert into the arc-shaped limiting groove inside the fixed base 2, so that the two ends of the roll 306 abut against the inside of the arc-shaped limiting groove, so that it will not deviate with the rotation of the feeding. The locking block 301 is inserted into the groove at the top of the rotating plate 303 under the action of the spring 302, thereby locking the rotating plate 303 and preventing the rotating plate 303 from accidentally opening by rotating outward. After pulling one end of the roll through the machine box 1, the double-acting screw 401 is rotated by rotating the handle. The rotation of the double-acting screw 401 drives the threaded sleeve 403 to move on the outer surface of the double-acting screw 401, thereby causing the rotating rod 405 to rotate, driving the pressing shaft 402 to press the wide paper downward, preventing wrinkles from occurring when the roll is fed, and finally completing the feeding of the wide paper inkjet.
