Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment, specifically a positioning mechanism for inkjet printing equipment. Background Technology

[0002] Inkjet printers are industrial devices that use specific technologies to quickly and accurately print identification information on the surface of products, packaging, or other carriers. This identification information typically includes production date, shelf life, batch number, serial number, QR code, barcode, brand logo, etc. They are widely used in many industries such as food, beverage, pharmaceutical, cosmetic, electronics, and building materials, and are an important tool for product traceability, quality control, and brand identification.

[0003] Patent CN218986145U discloses a coding device. Specifically, the patent discloses a support frame that supports a conveyor belt, positioning it at a suitable height for operator use. The conveyor belt holds and transports packaging bags requiring coding. An I-beam frame allows a sliding block to move as needed. A connector restricts the installation and movement of the support frame. The support frame, along with a sliding ring and a telescopic rod, mounts the coding pad above the conveyor belt. The sliding ring, via the telescopic rod, moves the coding pad on the support frame, adjusting its position. The telescopic rod adjusts the height of the coding pad, making the device more user-friendly. The coding device consists of a coding pad, a telescopic rod, a sliding ring, a support frame, a connector, and a sliding block. The coding device is movably mounted on the I-beam frame on the support frame. The combination of the coding device and the conveyor device forms the coding equipment, making it more stable during use.

[0004] To address the aforementioned issues, existing technologies utilize components such as I-beams for precise coding. However, when using this coding method, slight undulations on the conveyor belt surface can cause materials to tilt, overturn, or shift position during transport. In such cases, the printhead cannot maintain a consistently perpendicular distance from the material, leading to coding position deviations and even complete omissions in coding.

[0025] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0026] Please see Figures 1 to 3 A positioning mechanism for a coding device includes a mounting frame 1, with a belt conveyor 2 embedded inside the mounting frame 1. A support frame 3 is fixedly mounted on one side of the outer wall of the mounting frame 1, and a support plate 4 is fixedly mounted on the top of the support frame 3. A sliding plate 5 is slidably connected to the front end of the support plate 4, and the top of the sliding plate 5 is fitted with the main body of the coding device 6. An adjustment mechanism 7 is provided on one side of the support frame 3. The adjustment mechanism 7 includes a motor 701, which is embedded on the other side of the outer wall of the mounting frame 1. A threaded rod 70 is fixedly mounted on the power output end of the motor 701. 2. A sliding block 703 is slidably connected to the outer wall of the threaded rod 702. A connecting plate 704 is fixedly installed at the top of the sliding block 703. Abutting blocks 705 are fixedly installed at both ends of the upper part of the connecting plate 704. A storage groove 706 is opened inside the support frame 3. A pull-out shell 707 extends out of the storage groove 706. A connecting rod 708 is fixedly installed on both sides inside the storage groove 706. A sleeve 709 is rotatably connected to the outside of the connecting rod 708. An electric cylinder 8 is embedded at the rear end of the support plate 4. A push block 9 is fixedly installed at the power output end of the electric cylinder 8.

[0027] By adopting the above technical solution, when an object arrives between the two belt conveyors 2, it is first detected by infrared sensing and a signal is sent to the PLC control terminal to stop the belt conveyor 2 and start the motor 701. The threaded rod 702 drives the sliding block 703, which in turn allows the connecting plate 704 to drive the contact block 705 to contact the object. Under the rotational contact of the sleeve 709, the object reaches the top of the support frame 3 and is then printed by the main body 6 of the inkjet printer. This avoids the influence of uneven thickness of the conveyor belt on the belt conveyor 2, which could cause the object to tilt and affect the printing effect. In addition, the rotational contact of the connecting rod 708 and the sleeve 709 leaves a gap so that the ink or debris generated by the main body 6 of the inkjet printer can fall into the pull-out shell 707 of the collection tank 706 for unified collection and cleaning, avoiding cleaning trouble caused by the conveyor belt. After the object is positioned by the motor 701 and corresponds to the main body 6 of the inkjet printer, it can be positioned and clamped from the other side with the help of the electric cylinder 8 and the push block 9, maintaining the stability of the printing process.

[0028] Specifically, such as Figure 1 and Figure 4As shown, a mounting shell 10 is fixedly installed on one side of the storage groove 706 at the top of the support frame 3. A limiting mechanism 11 is provided inside the mounting shell 10. The limiting mechanism 11 includes a spring 1101. The spring 1101 is embedded in the outer wall of the mounting shell 10. A positioning plate 1102 is fixedly installed at one end of the spring 1101. A fixing cylinder 1103 is fixedly installed on one side of the spring 1101 on the outer wall of the positioning plate 1102. A connecting rod 1104 extends out of the inside of the fixing cylinder 1103. A permanent magnet plate 1105 is sleeved on the outer wall of one end of the connecting rod 1104 that enters the mounting shell 10. A limiting plate 1106 is fixedly installed at one end of the connecting rod 1104 that exits the permanent magnet plate 1105. An electromagnet 1107 is embedded in one side of the inside of the mounting shell 10.

[0029] By adopting the above technical solution, when the object moves towards the carrier 3 driven by the contact block 705, the two ends are attached to the positioning plate 1102 and the spring 1101 is compressed, leaving space for the object. Under the fixation of the mounting shell 10, the spring 1101 pushes the positioning plate 1102 to clamp the object. Then, the electromagnet 1107 pushes the permanent magnet plate 1105, and the rotating and engaging limit plate 1106 drives the connecting rod 1104 and the fixing cylinder 1103 to make the positioning plate 1102 attach and press the object. The fixing cylinder 1103 and the connecting rod 1104 are adjusted according to the size of the object to maintain the same size and clamp and position the object from both sides, avoiding the displacement. This allows the object to be positioned in four directions, maintaining the stability of the coding process.

[0030] Working principle: The mounting frame 1, by setting up two sets of belt conveyors 2, can reserve space for the sliding block 703. The mounting frame 1 is equipped with an infrared sensor. When the sensed object is located between the two belt conveyors 2, the mounting frame 1 stops and starts the motor 701, which drives the threaded rod 702. This pushes the sliding block 703 to move the connecting plate 704, allowing the contact block 705 to contact the object onto the support frame 3 on one side. The support frame 3 is equipped with a drive assembly consisting of the motor 701 and the threaded rod 702, which allows the sliding plate 5 to move along the support plate 4, and drives the main body 6 of the inkjet printer to approach the object. In the inkjet printing operation, the main body 6 of the inkjet printing equipment can be installed and fixed as needed, such as ink-based, resin-based, or laser-engraved types. The support frame 3, through the pull-out shell 707 inserted into the storage groove 706, can collect ink leaking from the main body 6 of the ink-based inkjet printing equipment or debris from the laser-engraved type. It is also equipped with an infrared sensor to detect objects, thereby allowing the PLC control terminal to close the motor 701 to prevent object misalignment. The connecting rod 708 rotates the engaging sleeve 709 to support the object for displacement, while leaving a pre-drilled hole to allow ink or debris to enter the storage groove 706. When the object is positioned, the electric cylinder 8 drives the push... The moving block 9 abuts against the object on the abutting block 705, thus achieving a positioning effect. Simultaneously, when the object enters the range of the support frame 3, it abuts against the positioning plate 1102, compressing the spring 1101. This causes the positioning plate 1102 to shift according to the object's size. Simultaneously, the electromagnet 1107 embedded in the mounting housing 10, when energized, pushes the permanent magnet plate 1105 with the same magnetic pole, causing the fixed cylinder 1103 and connecting rod 1104 to abut against the positioning plate 1102 and clamp the object. This, combined with the permanent magnet plate 1105, prevents errors in the through-hole dimensions that could lead to inability to center the object and positioning deviation. The connecting rod 1104... By rotating and engaging the limiting plate 1106 with the permanent magnet plate 1105, the length between the connecting rod 1104 and the fixed cylinder 1103 can be adjusted according to the size of the object. This allows for object contact and positioning from both sides, improving versatility. After coding is completed, the motor 701 rotates in the reverse direction, causing the contact block 705 to reset the object. Then, the belt conveyor 2 continues to be started for conveying. The entire equipment is equipped with a PLC control terminal, which can control the automatic components such as the belt conveyor 2 and the coding equipment body 6, and pre-programs are used to maintain automated operation.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
