Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4This utility model provides a technical solution: a printing device, comprising: a main support 1; an inner support box 15 bolted to the inner side of the main support 1, with sliding supports 16 symmetrically slidably disposed on the top of the inner support box 15; a bidirectional adjustment unit disposed inside the inner support box 15, the sliding supports 16 being connected to the bidirectional adjustment unit; a first belt conveyor 17 bolted to the inner side of the sliding supports 16, a second belt conveyor 18 mounted on the top of the sliding supports 16; and a fixed bracket 6 disposed outside the main support 1, one side of the fixed bracket 6 bolted to the inner side of the main support 1. A linear module 7 is installed, and a coding machine 8 is installed on the movable slide of the linear module 7. The printing section is set on the fixed bracket 6. The conveying section is located inside the main bracket 1. The conveying section includes an inner support frame 2, a rotating roller 3, and a first conveyor belt 4. Two inner support frames 2 are set inside the main bracket 1. A rotating roller 3 is rotatably set inside the two inner support frames 2. The rotating roller 3 is rotatably connected to the main bracket 1. A first conveyor belt 4 is symmetrically set outside the two rotating rollers 3. The two rotating rollers 3 are connected by the first conveyor belt 4.

[0025] It should be noted that in this embodiment, the conveying system mainly consists of a main support 1, inner support frames 2, rotating rollers 3, a first conveyor belt 4, and a first servo motor 5. The main support 1 serves as the supporting frame for the entire equipment, providing the installation foundation for other components. Two inner support frames 2 are symmetrically arranged inside the main support 1 to support the rotating rollers 3. The rotating rollers 3 are rotatably connected to the main support 1. The first conveyor belt 4 is symmetrically arranged outside the two rotating rollers 3, and the transmission connection is achieved through the first conveyor belt 4. The first servo motor 5 is installed on one side of the main support 1, and its output end is fixedly connected to one end of one of the rotating rollers 3. When the first servo motor 5 starts, its output shaft drives the rotating roller 3 connected to it to rotate. The rotating roller 3 transmits power to the other rotating roller 3 through the first conveyor belt 4, thereby causing the first conveyor belt 4 to start circulating. Items placed on the first conveyor belt 4 are conveyed and transported by the movement of the first conveyor belt 4. The conveyor belt 4 is transported to the printing area. Servo motor 5, characterized by high control precision, smooth operation, and stable torque output, can precisely adjust the conveying speed of conveyor belt 4 according to actual production needs, meeting the requirements of different production rhythms and printing processes for conveying speed, ensuring the stability and accuracy of the conveyed items. The adjustment system mainly revolves around the bidirectional adjustment section within the inner support box 15, used to adjust the positions of conveyor belt 17 and conveyor belt 18 to accommodate the conveying needs of items of different sizes. When it is necessary to adjust the positions of conveyor belt 17 and conveyor belt 18 according to the size of the item, servo motor 21 is activated. Servo motor 21 drives bidirectional lead screw 20 to rotate. Due to the bidirectional thread of lead screw 20, two moving blocks 22 symmetrically installed on the outside of lead screw 20 move simultaneously in opposite directions. During the movement, the moving blocks 22 drive the sliding support 16 fixed to them to move, thereby achieving bidirectional adjustment of the positions of conveyor belt 17 and conveyor belt 18. The setting of the limit rod 23 further ensures the linearity and stability of the movement of the moving block 22 and prevents it from deviating.The first gusseted cloth 24, installed between the two sides of the movable block 22 and the inner support box 15, prevents dust and debris from entering the inner support box 15, protects the components of the bidirectional adjustment unit from damage, extends the service life of the equipment, and ensures the long-term stable operation of the bidirectional adjustment function. The printing system is set on the fixed bracket 6, including the combination of the first linear module 7 and the first inkjet printer 8, the second linear module 9 and the second inkjet printer 10, the third linear module 11 and the third inkjet printer 12, and the fourth inkjet printer 14 installed on the mounting bracket 13. The fixed bracket 6 is located outside the main bracket 1, providing stable support for the printing system. The first linear module 7 is installed on one side of the fixed bracket 6, and the first inkjet printer 8 is installed on its movable slide. The second linear module 9 and the third linear module 11 are respectively installed inside the fixed bracket 6. The second linear module 9 is installed with the second inkjet printer 10 via the movable slide, and the third linear module 11 is installed with the third inkjet printer 12 via the movable slide. Mounting bracket 13 is bolted to the inside of fixed bracket 6. A fourth inkjet printer 14 is mounted on one side of the mounting bracket. During printing operations, based on the printing requirements of the item, the servo motors of each linear module are controlled to move the corresponding inkjet printer horizontally to the designated position. The installation height of each inkjet printer can be adjusted through installation and removal operations to accommodate printing operations on items of different sizes, shapes, and positions. This combination design of multiple inkjet printers and multiple linear modules allows the equipment to perform multiple printing operations with different content and requirements simultaneously, greatly improving the flexibility and accuracy of printing, expanding the equipment's applicability, and increasing production efficiency and printing quality. To ensure the stability of the sliding support 16's movement, limiting slide rods 19 are symmetrically fixed to the outside of the sliding support 16. The limiting slide rods 19 are slidably connected to the main support 1. When the bidirectional adjustment unit drives the sliding support 16 to move, the limiting slide rods 19 slide along the main support 1, providing additional guidance and support for the movement of the sliding support 16. This design can effectively prevent the sliding support 16 from shaking, shifting, or tilting during movement, ensuring the straightness and stability of the sliding support 16's movement. This, in turn, ensures the positional accuracy of the first belt conveyor 17 and the second belt conveyor 18 installed on the sliding support 16, which is beneficial to improving the overall operational stability and printing accuracy of the equipment.

[0026] The pressure roller is selected based on the actual items being conveyed during operation. The core principle of the pressure roller is to maintain the stability of the processed or conveyed object by applying pressure. The installation point of the pressure roller is determined according to the equipment structure to ensure that its direction of action is perpendicular to the direction of object movement and acts directly on the surface of the item. Pressure adjustment: The pressure roller pressure is adjusted by devices such as springs, hydraulics, or mechanical screws. During initial debugging, the pressure should be gradually increased, and the changes in the state of the object should be observed to avoid excessive pressure that could damage the equipment or deform the object. Gap control: In scenarios where the thickness of the object needs to be controlled, the gap between the pressure roller and the worktable must be precisely adjusted. This can be done by measuring with a feeler gauge or by calibrating with the scale provided with the equipment.

[0027] The specific architecture and operation logic of the belt conveyor, servo motor and linear module in this application to achieve coordinated control through an external controller are consistent with the existing technology in this field. The servo motors used are all equipped with encoders, which can provide real-time feedback on the speed, position and other information of the servo motor. This control method has been maturely applied in many similar industrial scenarios, so it will not be discussed in detail here.

[0028] Linear module components are divided into screw-driven and cylinder-driven types. The screw-driven type includes a mounting guide bracket, a moving slide, a screw system, a servo motor, a nut connected to the slide, and a protective device. The cylinder-driven type consists of a cylinder, a guide rail, a moving slide, and a mounting bracket. In terms of working principle, the screw-driven type uses a servo motor to rotate the screw nut linearly to drive the slide. The cylinder-driven type uses compressed air to push a piston to drive the slide. The intake and exhaust can be controlled to adjust the speed and stroke. Both types have protective devices to prevent dust and impurities, extend service life, and ensure stable accuracy.

[0029] In one embodiment, such as Figures 1 to 4 As shown, the printing unit includes a second linear module 9, a second inkjet printer 10, a third linear module 11, and a third inkjet printer 12. The second linear module 9 is bolted to the inside of the fixed bracket 6. The second inkjet printer 10 is mounted on the second linear module 9 via a movable slide. The third linear module 11 is bolted to the inside of the fixed bracket 6. The third inkjet printer 12 is mounted on the third linear module 11 via a movable slide.

[0030] It should be noted that in this embodiment, by setting up a combination structure of No. 2 linear module 9 and No. 2 inkjet printer 10, and No. 3 linear module 11 and No. 3 inkjet printer 12 inside the fixed bracket 6, the inkjet printers are moved linearly by the moving slide of the linear module. This design allows No. 2 inkjet printer 10 and No. 3 inkjet printer 12 to be precisely adjusted to different positions in the horizontal direction according to the actual printing requirements. The installation height of each inkjet printer can be adjusted by installation and disassembly, thereby meeting the printing requirements of items of different sizes, shapes and positions, greatly improving the flexibility and accuracy of printing, and expanding the applicability of the equipment.

[0031] In one embodiment, such as Figure 4 As shown, a mounting bracket 13 is bolted to the inner side of the fixed bracket 6, and a No. 4 inkjet printer 14 is bolted to one side of the mounting bracket 13.

[0032] It should be noted that in this embodiment, the No. 4 inkjet printer 14 is installed inside the fixed bracket 6 by mounting bracket 13, which adds an additional independent printing station to the printing equipment. This allows the equipment to perform multiple printing operations with different content and requirements at the same time, enriching the functions and diversity of printing, and improving production efficiency and printing effect.

[0033] In one embodiment, such as Figure 3 As shown, the bidirectional adjustment unit includes a bidirectional lead screw 20, a moving block 22, a limit rod 23, and a second servo motor 21. The bidirectional lead screw 20 is rotatably mounted inside the inner support box 15. The moving blocks 22 are symmetrically mounted on the outer side of the bidirectional lead screw 20. The moving blocks 22 are slidably connected to the inner support box 15. The top of the moving blocks 22 is fixedly connected to the sliding support 16. The second servo motor 21 is bolted to one side of the inner support box 15. The output end of the second servo motor 21 is fixedly connected to the bidirectional lead screw 20. A first accordion cloth 24 is provided between both sides of the moving blocks 22 and the inner support box 15.

[0034] It should be noted that in this embodiment, the second servo motor 21 drives the bidirectional lead screw 20 to rotate, which in turn drives the moving blocks 22, which are symmetrically installed on the outside of the bidirectional lead screw 20, to move in opposite directions at the same time. Since the moving blocks 22 are slidably connected to the inner support box 15 and their tops are fixed to the sliding support 16, the bidirectional stable adjustment of the sliding support 16 is realized. The limiting rod 23 further ensures the linearity and stability of the movement of the moving blocks 22 and prevents them from deviating.

[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, a servo motor 5 is installed on one side of the main support 1, and one end of one of the rotating rollers 3 is fixedly connected to the output end of the servo motor 5.

[0036] It should be noted that in this embodiment, the No. 1 servo motor 5 has the characteristics of high control precision, smooth operation, and stable torque output. It can provide stable and reliable power support for the No. 1 conveyor belt 4 of the conveying unit. Through the precise control of the No. 1 servo motor 5, the conveying speed of the No. 1 conveyor belt 4 can be precisely adjusted to meet the requirements of different production rhythms and printing processes for the conveying speed of items, ensuring the stability and accuracy of items during the conveying process, thereby improving the working efficiency and printing quality of the entire printing equipment.

[0037] In one embodiment, such as Figures 1 to 3As shown, a limiting slide rod 19 is symmetrically fixed to the outer side of the sliding support 16, and the limiting slide rod 19 is slidably connected to the main support 1.

[0038] It should be noted that in this embodiment, the limiting slide bar 19 provides additional guidance and support for the movement of the sliding support 16. When the bidirectional adjustment unit drives the sliding support 16 to move, the limiting slide bar 19 slides along the main support 1, which can effectively prevent the sliding support 16 from shaking, shifting or tilting during the movement, ensuring the straightness and stability of the movement of the sliding support 16, thereby ensuring the positional accuracy of the first belt conveyor 17 and the second belt conveyor 18 installed on the sliding support 16, which is conducive to improving the operational stability and printing accuracy of the entire equipment.
