[0033] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0034] Reference Figure 1-2 As shown, a conveying mechanism for calibrating materials in this embodiment includes a conveying platform 1 and a transfer device 2. The conveying platform 1 includes a bracket 11 and a conveying assembly 12 provided on the bracket 11. The conveying assembly 12 includes a driving member 121 and a plurality of conveying rollers 122. The plurality of conveying rollers 122 are linked with the driving member 121 and driven to rotate by the driving member 121. A baffle 3 is provided on the bracket 11, and the baffle 3 is used for abutting the edge of the material to be conveyed. The conveying roller 122 is used to convey the material to be conveyed and to form a displacement in the first direction and the second direction of the material to be conveyed until the material to be conveyed abuts the baffle 3 (refer to FIG. 1 ). Figure 2 As shown in the direction of the arrow, Figure 2 The left-pointing arrow in the figure is the first direction, and the right-pointing arrow is the second direction). The first direction is the displacement direction of the material to be delivered toward the baffle 3, and the second direction is the direction in which the material to be delivered needs to be delivered. The transfer device 2 is used to obtain the material to be delivered and transfer it to the transfer roller 122. The material to be delivered is a hard material.

[0035] In this embodiment, a drive element 121 drives a conveyor roller 122 to rotate synchronously. After a hard material (such as sheet material, acrylic, or glass) is placed onto the conveyor roller 122 by the transfer device 2, the rotation of the conveyor roller 122 displaces the material in a second direction (the conveying direction). Simultaneously, the rotation of the conveyor roller 122 displaces the material in a first direction, gradually moving it toward the baffle 3. Position calibration is completed when the edge of the material abuts the baffle 3. Through the bidirectional displacement of the conveyor roller 122 and the position limiting function of the baffle 3, the material is automatically calibrated during the conveying process, eliminating the need for manual intervention. This significantly improves calibration efficiency and is suitable for the stable conveying of hard materials. With the help of the transfer device 2, the material can be transferred to the conveyor roller 122, completing the entire process of material acquisition, material transfer, material calibration, and material transfer. This mechanism is particularly suitable for printing equipment, capable of transferring and calibrating hard materials to be printed, facilitating high-precision printing.

[0036] 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, solving the problem of traditional calibration relying on experience. The materials to be delivered can be placed on the conveying roller 122 with the help of the transfer device 2, and the requirements for the placement position are low. This solution can form an efficient and simple structural calibration solution for materials to be delivered, which is especially suitable for large-sized materials to be delivered.

[0037] 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).

[0038] The driving member 121 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 desired conveying direction of the material to be conveyed.

[0039] For further settings, refer to Figure 3 、 4 As shown in Figures 8 and 9, the transfer device 2 includes two swing arms 21, a driver 22 for driving the two swing arms 21 to swing back and forth, and a negative pressure suction device 23 installed on the swing arms 21. The driver 22 drives the swing arms 21 to swing and moves the negative pressure suction device 23 back and forth between the first position and the second position; the two swing arms 21 rotate through a fulcrum 24 at a fixed position.

[0040] In this solution, the driver 22 drives the swing arm 21 to swing about fulcrum 1 24, driving the negative pressure suction device 23 to reciprocate between two fixed positions (a first position and a second position). When the swing arm 21 swings to the first position, the negative pressure suction device 23 absorbs the print medium; when the swing arm 21 swings to the second position, the negative pressure suction device 23 releases the print medium to the conveyor assembly 12. The single-degree-of-freedom swing of the swing arm 21 simplifies the mechanical design of the transfer path and reduces the reliance on drive accuracy. This is particularly suitable for the transfer of rigid, plate-like materials.

[0041] The swing arm 21 can be rotatably connected to the fulcrum 1 24, allowing the swing arm 21 to rotate with the fulcrum as a hinge point, so that the trajectory of each swing is stable and controllable. The driver 22 can be driven by a motor or a power push rod, and the power push rod can be a pneumatic push rod, a gas pressure push rod, an electric push rod, etc. The negative pressure suction device 23 can be composed of a negative pressure suction cup 233 and an air pump. The air pump can be used to drive the negative pressure suction cup 233 to generate negative pressure, thereby adsorbing the hard plate-shaped printing medium.

[0042] As an implementation scheme that can make the printing medium transfer process more stable, the negative pressure suction device 23 includes a connecting shaft 231 for connecting the swing arm 21, a frame 232 installed on the connecting shaft 231, and a number of negative pressure suction cups 233 installed on the frame 232; the frame 232 is rotatably installed on the connecting shaft 231.

[0043] The frame 232 is hinged to the swing arm 21 via a connecting shaft 231, allowing the frame 232 to rotate about the connecting shaft 231. As the swing arm 21 swings, the frame 232's rotational freedom can be used to adjust the print medium's position. For example, in the first position, the print medium is flat. Rotation of the frame 232 allows the print medium to be conveyed in a flat position as much as possible, and then released onto the conveyor assembly 12 in a flat position. The distributed layout of the multiple negative pressure suction cups 233 further enhances the uniformity of suction force and avoids localized stress concentration that can cause material deformation.

[0044] As a solution to make the state control during the transfer of auxiliary printing media more stable, this solution can also add a balance bar 25, which is rotatably connected to the frame 232 and is also rotatably connected to a fulcrum 26 at a fixed position; when the swing arm 21 swings, the balance bar 25 swings synchronously and keeps the frame 232 in a horizontal state.

[0045] One end of the balance bar 25 is hinged to the frame 232, and the other end swings about pivot point 26. When the swing arm 21 drives the frame 232 to move, the balance bar 25 suppresses tilt of the frame 232 by swinging synchronously, ensuring that the frame 232 remains horizontal (for example, to ensure the smooth release of hard sheet materials during transport). The distance between pivot point 26 and pivot point 1 24 is equal to the distance between the connection point between the balance bar 25 and the frame 232 and the connection point between the connecting shaft 231 and the swing arm 21. This further ensures the synchronization and stability of the balance bar 25 and the swing arm 21, and better controls the state of the frame 232. Of course, a certain deviation in this distance will cause the frame 232 to tilt to a certain extent, which will also affect the state of the printing medium. However, if it meets the requirements, a certain deviation in this distance is acceptable.

[0046] Preferably, when the swing arm 21 swings, the position angular velocity of the connection between the swing arm 21 and the connecting shaft 231 is the same as the position angular velocity of the connection between the balance bar 25 and the frame 232 .

[0047] By matching the angular velocities of the swing arm 21 and the balance bar 25, the motion trajectory of the frame 232 is ensured to be purely translational (i.e., without rotational components). This design avoids the problem of suction cup tilt caused by angular velocity differences in traditional swing mechanisms, improving the positioning accuracy of rigid sheet materials. Furthermore, it offers a simple structure and stable transport. The translational motion of the frame 232 can be achieved solely through mechanical design.

[0048] In order to facilitate installation and precision control, fulcrum 1 24 and fulcrum 2 26 are both located on a connecting member 27, and the connecting member 27 has a connecting portion for connecting the swing arm 21 and the balance bar 25, and the swing arm 21 and the balance bar 25 are rotatably connected to the connecting portion; the connecting member 27 is used to be fixedly connected to the external bracket 11.

[0049] Connector 27 serves as a common mounting base for pivot point 1 24 and pivot point 2 26 and is secured to the printer frame via external bracket 11. The direct mounting of the swing arm 21 and balance bar 25 on connector 27 ensures proper pivot spacing and prevents deflection of the frame 232 due to assembly errors. The modular design of connector 27 simplifies disassembly and maintenance of the entire mechanism. Manufacturing connector 27 simply requires setting pivot points at fixed locations. For example, drilling holes in connector 27 and bolting the swing arm 21 and balance bar 25 together to form pivot point 1 24 and pivot point 2 26.

[0050] As an optional implementation scheme of the driver 22, the driver 22 includes an actuator 221, a rotating shaft 222, and two gears 223 arranged on the rotating shaft 222. The actuator 221 is linked to the rotating shaft 222, and the rotating shaft 222 is driven to rotate by the actuator 221. The positions of the corresponding gears 223 on the two swing arms 21 are provided with external teeth 211 arranged along a circular arc trajectory. The gears 223 engage with the external teeth 211 and drive the swing arms 21 to swing through the rotation of the rotating shaft 222.

[0051] Actuator 221 (e.g., a servo motor or stepper motor) drives shaft 222 to rotate (this can be accomplished using a worm gear or bevel gear 223), which in turn engages gear 223 with external teeth 211 of swing arm 21, converting the rotational motion into reciprocating swing of swing arm 21. The meshing path between gear 223 and external teeth 211 is designed to be circular, aligning with the swing path of swing arm 21 around pivot point 24, thereby reducing positioning errors caused by transmission backlash.

[0052] In a further configuration, a connecting hole 271 for passing the rotating shaft 222 is further provided on the connecting member 27 . The rotating shaft 222 is installed in the connecting hole 271 through a bearing, and the displacement of the rotating shaft 222 is limited by the connecting hole 271 .

[0053] The connection hole 271 of the rotating shaft 222 is limited, which can improve the meshing stability between the gear 223 and the external tooth 211, ensure the transmission cooperation between the two, and suppress axial movement and radial runout (such as vibration transmission when the gear 223 is engaged).

[0054] The connecting hole 271 can also be located on the connecting member 27, which is convenient for the one-time production of the connecting member 27. After the connecting member 27 is fixedly connected to the external bracket 11 by bolts, the positions of the connecting hole 271, fulcrum 1 24, and fulcrum 2 26 on the connecting member 27 can be determined, thereby ensuring the accuracy of each installation.

[0055] The above mainly describes the optional solutions of the transfer device 2. The following also describes the conveying component 12:

[0056] Among them, as a preferred solution: Figure 1 、 2 As shown in Figures 7 and 8, the end of the conveying roller 122 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 122 and the baffle 3 to form a displacement of the material to be conveyed in the first direction and the second direction.

[0057] The axis of the conveyor roller 122 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 122 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 this is not a required component; whether the conveyor roller 122 has conveyed the material to be tested and whether it has been calibrated 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.

[0058] The angle formed between the axis of the conveying roller 122 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.

[0059] In order to facilitate the synchronous movement of multiple conveying rollers 122, in an optional embodiment, referring to Figure 1 、 2As shown in FIG7 , a plurality of conveying rollers 122 are distributed along the second direction, and adjacent conveying rollers 122 in the direction are driven by the transmission member 123 , and at least one of the conveying rollers 122 is driven in cooperation with the driving member 121 through the transmission member 123 .

[0060] Adjacent conveyor rollers 122 are linked by transmission elements 123, which are also linked to the drive element 121. This allows the drive element 121 to simultaneously drive these conveyor rollers 122, facilitating more synchronized movement. This tandem transmission ensures consistent rotational speed across the entire row of conveyor rollers 122, preventing material shifting due to local speed differences. The linked design of transmission elements 123 simplifies power distribution and reduces manufacturing costs.

[0061] The specific transmission member 123 can be a belt or a chain. Correspondingly, a gear is provided on the conveying roller 122 to cooperate with the belt or the chain.

[0062] In a further configuration, the conveying rollers 122 distributed along the second direction are arranged as a column, and a plurality of columns are arranged in the first direction, and at least one conveying roller 122 in each column cooperates with the driving member 121 for transmission through the transmission member 123 .

[0063] A plurality of rows of conveying rollers 122 are provided in the first direction, and each row is connected to the driving member 121 via a transmission member 123. When the material enters, the plurality of rows of conveying rollers 122 simultaneously push the material to move in the first direction and the second direction.

[0064] As a solution to further simplify the driving structure, the output end of the driving member 121 is connected to a rotating shaft, and each conveying roller 122 that cooperates with the driving member 121 through the transmission member 123 is transmitted through the transmission member 123 and the rotating shaft to cooperate with the driving member 121.

[0065] The rotating shaft can be equipped with multiple gears to connect the transmission members 123 of each column of conveyor rollers 122 to the driver 121. The driver 121 drives the rotating shaft, synchronously driving each transmission member 123 on the rotating shaft. These transmission members 123 then rotate together with each column of conveyor rollers 122. The rotating shaft and the driver 121 can be connected by a coupling, or they can be driven by a gear set, chain, or belt. A single driver 121 distributes power across multiple columns through the rotating shaft, simplifying the transmission system and reducing costs.

[0066] 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 、 2As shown in Figures 6 and 7, the conveying assembly 12 also includes a plurality of conveyor belts 124 and a lifting assembly 125 for lifting the conveyor belts 124; the lifting assembly 125 is used to lift the conveyor belts 124 after the material to be conveyed abuts against the baffle 3, and the conveyor belt 124 is lifted up and passes over the conveying roller 122 and conveys the material to be conveyed.

[0067] When the material to be fed has been calibrated against the baffle 3, the lifting assembly 125 raises the conveyor belt 124 to a position higher than the conveyor roller 122. At this point, the conveyor belt 124 directly contacts the bottom surface of the material, replacing the conveyor roller 122 to continue conveying the material in the second direction. This operation can reduce the squeezing time between the baffle 3 and the edge of the material to be fed, while also concentrating the conveying effect in a single direction, resulting in higher conveying efficiency. The lifting assembly 125 starts to raise the conveyor belt 124 based on the fact that the conveyor roller 122 has been running for a fixed time of 10 seconds, 15 seconds, or 20 seconds, and 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. The sensor's trigger signal activates the lifting action of the lifting assembly 125, and after feeding is completed, it descends again to a position below the conveyor roller 122.

[0068] In the specific distribution of the conveyor belts 124, a plurality of conveyor belts 124 are respectively located between two adjacent rows of conveyor rollers 122 and / or between the conveyor rollers 122 and the baffle 3, referring to Figure 1 and 2 This setting can support and convey the material to be conveyed more evenly.

[0069] In order to facilitate the synchronous movement between multiple transmission belts, refer to Figure 6 As shown, the conveying assembly 12 further includes a connecting frame 126 , a plurality of conveyor belts 124 are mounted on the connecting frame 126 , and the lifting assembly 125 is connected to the connecting frame 126 , and the conveyor belts 124 are synchronously raised or lowered by lifting the connecting frame 126 .

[0070] Multiple conveyor belts 124 are connected to a connecting frame 126 to form a single module. Lifting assemblies 125 (e.g., multiple sets of synchronized cylinders) are connected to the connecting frame 126 at multiple locations. When the conveyor belts 124 need to be raised, the lifting assemblies 125 simultaneously lift the connecting frame 126, allowing all conveyor belts 124 to reach the preset height simultaneously. This design ensures a smooth raising and lowering of the conveyor belts 124, preventing material shifting due to unilateral tilting.

[0071] The above introduction is about a conveying mechanism for calibrable materials, which can be used in scenarios where hard materials need to be conveyed and calibrated. This solution is also particularly suitable for printing equipment, including a printing component, and a conveying mechanism for calibrable materials such as any of the above-mentioned preferred solutions for conveying materials to the printing component.

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.
