Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to an automatic pressing and conveying device. Background Technology

[0002] In the conveying and transporting of flexible materials, a combination of conveying rollers and pressure rollers is generally used to achieve the above-mentioned purpose. A drive mechanism typically moves the pressure rollers up and down. When the pressure roller moves upward, it separates from the conveying roller, and flexible materials cannot be conveyed in this state. When the pressure roller moves downward, it approaches the conveying roller, and the flexible material is pressed between them and can be conveyed. However, in this state, the two ends of the pressure roller are subjected to downward force, causing the middle of the pressure roller to arch and deform upward. This prevents the flexible material from adhering well to the surface of the conveying roller, affecting conveying accuracy and causing the flexible material to deviate during transport. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide an automatic pressing and conveying device with a clever structural design. A mechanical limiter is added below the sliding seat, which provides an upward support force to the sliding seat. This prevents the middle of the pressing roller from arching upward and instead causes a slight downward arching deformation. Ultimately, this ensures that the entire pressing roller deforms and presses the material in the direction of the conveying roller, thereby achieving precise conveying of flexible materials and preventing material deviation.

[0004] To solve the above-mentioned technical problems, the present invention provides an automatic pressing and conveying device, including two mounting seats, a conveying roller and a pressing roller located on both sides. The two mounting seats are connected by a mounting plate. The two ends of the conveying roller are rotatably connected to the two mounting seats respectively. The two ends of the pressing roller pass through the openings of the mounting seats and are respectively connected to a sliding seat. The sliding seats are slidably connected to the mounting seats by a Z-axis slider rail structure.

[0005] The mounting plate has a clamping drive cylinder fixedly installed at both ends, and the two ends of the pressure roller are respectively fitted with connecting seats. The end of the push rod of the clamping drive cylinder is fixed to the connecting seat, and the pressure roller is driven to rise and fall by the clamping drive cylinder.

[0006] The mounting base is provided with a top material structure located below the sliding base. The top material structure includes a connecting column and a top material screw. One end of the connecting column is fixed to the mounting base, and the top material screw is installed at the end of the connecting column, with its upper end able to abut against the sliding base and provide support for the sliding base.

[0007] Furthermore, both ends of the pressure roller are connected to the sliding seat via a bearing structure.

[0008] Furthermore, the height of the portion of the top screw extending out of the threaded hole of the connecting post can be adjusted.

[0009] Furthermore, the conveying roller is externally connected to a rotary drive unit capable of driving its rotation.

[0010] The beneficial effects of this utility model are:

[0011] This invention features a clever structural design. A mechanical limiting structure, or top-loading structure, is added below the sliding seat, providing upward support. This prevents the pressure roller from arching upwards; instead, it causes a slight downward deformation, causing the entire pressure roller to deform towards the conveying roller and press the material firmly. This achieves precise conveying of flexible materials and prevents material deviation. Therefore, this device does not require high straightness of the pressure roller, and can still achieve precise material conveying even when the pressure roller is slightly worn, extending its service life and reducing costs.

[0012] Furthermore, the height of the section of the top material screw extending out of the threaded hole of the connecting column can be adjusted. When conveying flexible materials of different thicknesses, the top material screw can be finely adjusted to ensure the most appropriate fit between the pressure roller and the conveying roller, thus guaranteeing the best conveying accuracy.

[0020] Example: An automatic material pressing and conveying device, such as Figure 1 and Figure 2 As shown, it includes two mounting seats 1 located on both sides, a conveying roller 2 and a pressure roller 3. The two mounting seats are connected by a mounting plate 4. The two ends of the conveying roller are rotatably connected to the two mounting seats respectively. The two ends of the pressure roller pass through the openings 11 of the mounting seats and are respectively connected to a sliding seat 5. The sliding seats are slidably connected to the mounting seats by a Z-axis slider rail structure 6.

[0021] The mounting plate has a pressing drive cylinder 7 fixedly installed at both ends. The two ends of the pressing roller are respectively fitted with connecting seats 31. The end of the push rod of the pressing drive cylinder is fixed to the connecting seat. The pressing roller is driven to rise and fall by the pressing drive cylinder.

[0022] The mounting base is provided with a top material structure located below the sliding seat. The top material structure includes a connecting column 8 and a top material screw 9. One end of the connecting column is fixed to the mounting base, and the top material screw is installed at the end of the connecting column, with its upper end able to abut against the sliding seat and provide support for the sliding seat.

[0023] In this embodiment, the two ends of the pressure roller are connected to the sliding seat through the bearing structure 10.

[0024] In this embodiment, the height of the section of the top screw extending out of the threaded hole of the connecting column can be adjusted. When conveying flexible materials of different thicknesses, the top screw can be finely adjusted to ensure the optimal fit between the pressure roller and the conveying roller, guaranteeing the best conveying accuracy.

[0025] In this embodiment, the conveying roller is externally connected to a rotary drive unit that can drive its rotation, such as relying on a motor drive, which is existing technology and will not be described in detail.

[0026] The working principle and process of this utility model:

[0027] Working process: The flexible material passes between the pressure roller and the conveying roller. The pressure drive cylinder drives the pressure roller to press down. At this time, the top screw can generate an upward supporting force on the sliding seat. The pressure roller presses the flexible material onto the surface of the conveying roller, and the rotation of the conveying roller drives the flexible material to be conveyed.

[0028] Working principle: A mechanical limiting structure, or top material structure, is added below the sliding seat, providing an upward supporting force. This prevents the middle of the pressure roller from arching upwards; instead, it causes a slight downward arching deformation. The entire pressure roller deforms towards the conveying roller, pressing the material firmly and achieving precise delivery of flexible materials, preventing material deviation. Therefore, this device does not have high requirements for the straightness of the pressure roller. Even when the pressure roller is slightly worn, it can still achieve precise material delivery, extending the service life of the pressure roller and reducing costs.
