[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0030] Reference Figure 1 、 2 , 3, 4, and 6, the present invention provides a printing material conveying mechanism, comprising a bracket 1 and a conveying assembly 2 arranged on the bracket 1, the conveying assembly 2 comprising a driving member 21 and a plurality of conveying rollers 22, the plurality of conveying rollers 22 being linked with the driving member 21 and driven to rotate by the driving member 21; a baffle 3 is provided on the bracket 1, the baffle 3 being used for abutting the edge of the material to be conveyed; the conveying roller 22 is used to convey the material to be conveyed and to form a first direction and a second direction displacement of the material to be conveyed until the material to be conveyed abuts the baffle 3, the first direction being the displacement direction of the material to be conveyed toward the baffle 3, and the second direction being the direction in which the material to be conveyed needs to be conveyed (refer to Figure 2 The arrows in the figure indicate the direction to the left, which is the first direction, and the arrows upward, which is the second direction).

[0031] In this scheme, a drive member 21 rotates several conveyor rollers 22. When the material being conveyed contacts the conveyor rollers 22, friction causes it to displace in the second direction. Simultaneously, because the baffle 3 is fixed to one side of the bracket 1, when the material is not in contact with the baffle 3, the conveyor rollers 22 push the material and simultaneously displace it in the first direction. When the edge of the material finally abuts the baffle 3, displacement in the first direction ceases, leaving only the second direction. This achieves automatic alignment of the material in both the horizontal and vertical directions.

[0032] This automatic calibration method does not require human intervention, realizes the coordinated displacement of materials in two directions, and does not require manual adjustment of limit blocks, which solves the problem of traditional calibration relying on experience. The materials to be transported can be placed on the conveying roller 22 with the help of other lifting devices or manual means, and has low requirements for the placement position. This solution can form an efficient and simple structural calibration solution for materials to be transported, which is especially suitable for large-sized materials to be transported.

[0033] The driving member 21 may be a motor, and the first direction and the second direction are combined to form a movement direction that gradually approaches the baffle 3 and gradually approaches the required conveying direction of the material to be conveyed.

[0034] The desired conveying direction of the material to be delivered can be the direction of the printer.

[0035] In this solution, the material being conveyed can be made of a hard material, such as sheet material, acrylic, or glass, which can form a more stable fit with baffle 3. The calibration mechanism is optimized for the rigidity of hard materials, improving positioning accuracy. Of course, flexible materials can also be used to fit with baffle 3, such as wide-format rigid paper (which is still a flexible material in essence).

[0036] In the above-mentioned scheme, as one of the preferred settings, the end of the conveying roller 22 away from the baffle 3 is inclined toward the direction in which the material to be conveyed is required to be conveyed, and an acute angle is formed between the axis of the conveying roller 22 and the baffle 3 to form a displacement of the material to be conveyed in the first direction and the second direction.

[0037] In this solution, the axis of the conveyor roller 22 forms an acute angle with the baffle 3 (e.g., 30° to 90°, excluding the 90° endpoint), so that when the surface of the conveyor roller 22 contacts the material, a force component is generated: the force component along the second direction pushes the material forward, and the force component along the first direction pushes the material toward the baffle 3. This tilted design directly achieves the synthesis of bidirectional displacement through a mechanical structure without the need for additional sensors or control programs. Of course, sensors can also be used to detect whether the current material to be conveyed has been calibrated, but these are not required components. Whether the conveyor roller 22 has completed the calibration of the material to be conveyed can also be set by a fixed conveying time. For example, after 15 seconds of conveying by the conveyor roller, it can be basically determined that the edge of the material to be conveyed has reached the baffle 3. Of course, this time length is only for example, and those skilled in the art can set it to 10 seconds or 20 seconds according to actual conditions.

[0038] The angle formed between the axis of the conveying roller 22 and the baffle 3 can be adjusted according to the actual conveying stroke. For example, if the stroke is short, the angle can be smaller; if the stroke is long, the angle can be larger. When the angle is large, the thrust toward the side of the baffle 3 is relatively small, which will not cause excessive pressure on the baffle 3. At the same time, it also reduces the friction loss between the baffle 3 and the material to be conveyed, avoids positioning deviation caused by violent collisions, etc., but the stroke required for calibrating the material to be conveyed will also be longer. When the angle is small, the stroke for calibrating the material to be conveyed is short, but it is also easy to cause greater pressure on the baffle 3, and it is also easy to generate greater friction and loss between the two. Therefore, those skilled in the art can make a choice according to the needs.

[0039] In order to facilitate the synchronous movement of multiple conveying rollers 22, in an optional embodiment, referring to Figure 2 and 3 As shown, a plurality of conveying rollers 22 are distributed along the second direction, and adjacent conveying rollers 22 in the direction are driven by the transmission member 4 , and at least one of the conveying rollers 22 is driven in cooperation with the driving member 21 through the transmission member 4 .

[0040] Adjacent conveyor rollers 22 are linked by transmission element 4, which is also connected to the drive element 21. This allows the drive element 21 to simultaneously drive these conveyor rollers 22, achieving more synchronized movement. This tandem transmission ensures consistent rotational speed across the entire row of conveyor rollers 22, preventing material shifting due to local speed differences. The linked design of transmission element 4 simplifies power distribution and reduces manufacturing costs.

[0041] Concrete transmission member 4 can adopt belt or chain.Correspondingly, gear can be provided on the transmission roller 22, and is used for matching belt or chain.

[0042] In a further configuration, the conveying rollers 22 distributed along the second direction are arranged as a column, and several columns are arranged in the first direction, and at least one conveying roller 22 in each column cooperates with the driving member 21 to convey through the transmission member 4.

[0043] A plurality of rows of conveying rollers 22 are provided in the first direction, and each row is connected to the driving member 21 via a transmission member 4. When the material enters, the plurality of rows of conveying rollers 22 simultaneously push the material to move in the first direction and the second direction.

[0044] As a solution to further simplify the driving structure, the output end of the driving member 21 is connected to the rotating shaft 5, and each conveying roller 22 that is transmitted through the transmission member 4 and the driving member 21 is transmitted through the transmission member 4 and the rotating shaft 5 to form a cooperation with the driving member 21.

[0045] The rotating shaft 5 can be equipped with multiple gears to connect the transmission members 4 of each column of conveyor rollers 22 to the driver 21. The driver 21 drives the rotating shaft 5 to rotate, synchronously driving each transmission member 4 on the rotating shaft 5. These transmission members 4 then rotate together with each column of conveyor rollers 22. The rotating shaft 5 and the driver 21 can be connected via a coupling, or they can be driven by a gear train, chain, or belt. A single driver 21 distributes power across multiple columns through the rotating shaft 5, simplifying the transmission system and reducing costs.

[0046] In addition, in an optional solution to reduce the squeezing time between the material to be sent and the baffle 3, refer to Figure 1 、 2 As shown in Figures 3, 5, and 6, the conveying assembly 2 also includes a plurality of conveyor belts 23 and a lifting assembly 24 for lifting the conveyor belts 23; the lifting assembly 24 is used to lift the conveyor belts 23 after the material to be conveyed abuts against the baffle 3, and the conveyor belt 23 is lifted up to pass over the conveying roller 22 and convey the material to be conveyed.

[0047] When the material to be fed abuts the baffle 3 and completes calibration, the lifting assembly 24 lifts the conveyor belt 23 to a position higher than the conveyor roller 22. At this time, the conveyor belt 23 directly contacts the bottom surface of the material, replacing the conveyor roller 22 to continue conveying the material in the second direction. In this operation, the squeezing time between the baffle 3 and the edge of the material to be fed can be reduced, and the conveying effect can also be more concentrated in a single direction, resulting in higher conveying efficiency. The action of the lifting assembly 24 starting to raise the conveyor belt 23 can be based on the fact that the aforementioned conveyor roller 22 has been running for a fixed time of 10 seconds, 15 seconds, or 20 seconds, and it can be started when it is basically determined that the material to be fed has reached the baffle 3. Of course, a sensor can also be added to trigger when the material to be fed reaches the baffle 3, and the lifting action of the lifting assembly 24 is started by the trigger signal of the sensor, and it descends again to a state below the conveyor roller 22 after the feeding is completed.

[0048] In the specific distribution of the conveyor belts 23, a plurality of conveyor belts 23 are respectively located between two adjacent rows of conveyor rollers 22 and / or between the conveyor rollers 22 and the baffle 3, referring to Figure 2 This setting can support and convey the material to be conveyed more evenly.

[0049] In order to facilitate the synchronous movement between multiple transmission belts, refer to Figure 5 As shown, the conveying assembly 2 further includes a connecting frame 25 , a plurality of conveyor belts 23 are mounted on the connecting frame 25 , and the lifting assembly 24 is connected to the connecting frame 25 , and the conveyor belts 23 are synchronously raised or lowered by lifting the connecting frame 25 .

[0050] Multiple conveyor belts 23 are connected to a connecting frame 25 to form a single module. Lifting assemblies 24 (e.g., multiple sets of synchronized cylinders) are connected to the connecting frame 25 at multiple locations. When the conveyor belts 23 need to be raised, the lifting assemblies 24 simultaneously lift the connecting frame 25, allowing all conveyor belts 23 to reach the preset height simultaneously. This design ensures a smooth raising and lowering of the conveyor belts 23, preventing material shifting due to unilateral tilting.

[0051] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
