[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-9 An integrated multi-color automatic inkjet printing device for stainless steel thermos cups includes a support frame 3, on which a thermos cup feeding device and a conveyor 8 are mounted. The thermos cup feeding device includes a hopper 2 and a rotating mechanism 5 mounted on the support frame 3, which transfers materials between the hopper 2 and the conveyor 8. The support frame 3 also includes an inkjet printing and curing device, which includes an inkjet printing mechanism 4 and a curing structure. Both the inkjet printing mechanism 4 and the curing structure are mounted on the support frame 3 and located on the rotating conveyor track of the rotating mechanism 5. The inkjet printing mechanism 4 is used to print on the stainless steel thermos cups, and the curing structure is used to cure the printed materials. The support frame 3 also includes a device located between the inkjet printing mechanism 4 and the curing structure. The stainless steel thermos cup to be processed is placed in the material hopper 2 and conveyed to the clamping and rotating structure 7 by the rotating mechanism 5. The clamping and rotating structure 7 clamps and drives the stainless steel thermos cup to rotate. During the rotation, the inkjet printing mechanism 4 performs inkjet printing, and the curing structure performs photocuring. Finally, the rotating mechanism 5 conveys it to the conveyor 8, and the conveyor 8 delivers it out. The stainless steel thermos cup feeding, inkjet printing, curing, and unloading processes are integrated on the support frame 3. The rotating mechanism 5 realizes the automatic transfer of materials between each process, reduces manual intervention or additional transfer equipment, shortens the processing flow, reduces the waiting time between processes, improves the efficiency of batch production, ensures the smooth connection between inkjet printing and curing processes, and improves the product processing quality and yield.

[0020] The support frame 3 is equipped with a protective device, which includes a cabinet 1 bolted to the bottom of the support frame 3, a protective box 101 bolted to the top of the cabinet 1, a discharge port 102 on the protective box 101, and one end of the conveyor 8 extending from the discharge port 102 to the outside of the protective box 101. The cabinet 1 provides support for the support frame 3 and the conveyor 8, and the protective box 101 is used to provide protection to improve the safety of the equipment during operation.

[0021] Two light gratings are bolted to the inner wall of the protective box 101. The two light gratings are located on both sides of the discharge port 102, which provides the necessary channel for the stainless steel thermos cup to be discharged outward after processing.

[0022] The bottom of the cabinet 1 is threaded with several feet 106, which are used for leveling the bottom of the cabinet 1.

[0023] The top of the hopper 2 is the feeding port, which is located outside the protective box 101. The bottom of the hopper 2 is provided with a discharge port 201, and the bottom wall of the hopper 2 is inclined towards the discharge port 201. This arrangement allows the stainless steel thermos cup to roll out from the discharge port 201 under the action of gravity. The width of the hopper 2 is set according to the length of the stainless steel thermos cup.

[0024] The protective box 101 has an operating port on the front, and a cabinet door 103 is hinged to the operating port. A lock is installed between the cabinet door 103 and the protective box 101, and a transparent window is installed on the cabinet door 103. The operating port is used to provide an operating channel for maintenance.

[0025] The protective box 101 is also equipped with a light grid at the operation port. This setting allows an alarm to be triggered if someone accidentally opens the cabinet door 103 and enters the operation port during equipment operation.

[0026] An audible and visual alarm 104 is bolted to the top of the protective box 101. The audible and visual alarm 104 works in conjunction with the light grating to trigger an alarm.

[0027] In actual production applications, existing inkjet printers have insufficient safety protection design, which leads to many safety hazards for operators and also affects the operational stability of the equipment itself. Currently, most existing inkjet printers adopt an open or semi-closed casing design. If human error occurs and the processing area is accidentally entered during operation, there may be safety hazards. This application sets up a grating in areas where human intrusion may occur. The grating's transmitter and receiver form an infrared protective light curtain, enabling accurate detection and identifying intrusions by small limb parts such as fingers. Once an operator's limb is detected to have entered a dangerous area of ​​the equipment, a safety signal is immediately triggered, causing the equipment to stop operating and triggering an alarm, thereby reducing safety hazards.

[0028] The printing mechanism 4 includes a linear module 401 that is bolted to a support frame 3. A connecting frame 402 is bolted to the moving end of the linear module 401. Several printing heads 403 are bolted to the connecting frame 402. The printing heads 403 are used to spray different colors.

[0029] Most existing inkjet printers use a fixed installation method for the printhead, which is not conducive to adjusting the printing spacing. When different patterns need to be printed, the printhead needs to be disassembled, reinstalled and adjusted, which is complicated and time-consuming. This application uses a linear module 401 to drive the connecting frame 402 and the print head 403 to move, thereby adjusting the horizontal position of the print head 403 according to the print pattern, which is convenient and efficient for adjusting the print spacing and reduces manual operation.

[0030] The curing structure includes a UV curing lamp 601, on which several second support plates 6 are bolted. The second support plates 6 are bolted to a support frame 3. The second support plates 6 are used to provide support for the UV curing lamp 601. The UV curing lamp 601 is used to perform UV curing operation on the printed stainless steel thermos cup.

[0031] The inner side of the second support plate 6 is arc-shaped to avoid the turntable 501.

[0032] The rotating mechanism 5 includes two first support plates 505 bolted to the support frame 3. Each of the two first support plates 505 is bolted to a bearing seat, and the two bearing seats are connected by a drive shaft 507 via a bearing. The drive shaft 507 is provided with a support member, and the support member is provided with several slots 503. The slots 503 are used to provide an entry channel for the stainless steel thermos cup.

[0033] The support includes two turntables 501 that are fixedly connected to the drive shaft 507. The fixed connection can be made by welding or bolting. The slot 503 is formed on the turntable 501.

[0034] Several connecting rods 502 are bolted between the two turntables 501, and the connecting rods 502 can connect the two turntables 501 together.

[0035] The drive shaft 507 is also provided with a drive component, which is used to drive the drive shaft 507 and the turntable 501 to rotate.

[0036] The driving component includes a first motor frame 506 bolted to the support frame 3, a first drive motor 508 bolted to the first motor frame 506, and the output shaft of the first drive motor 508 connected to one end of the transmission shaft 507 via a coupling. The first drive motor 508 is used to drive the turntable 501 to rotate via the transmission shaft 507.

[0037] Traditional feeding methods rely heavily on manual operation. Workers need to manually place the thermos cups one by one onto the printing station of the inkjet printer. This is labor-intensive, has high labor costs, and the manual feeding speed is limited. This application utilizes a hopper 2 and a rotating mechanism 5. The hopper 2 is used to store stainless steel thermos cups. The hopper 2 and the rotating mechanism 5 work together to achieve automated feeding and conveying of stainless steel thermos cups. This allows workers to simply store the stainless steel thermos cups in the hopper 2 in advance, while the rotating mechanism 5 automatically feeds the cups into the processing area. This reduces the labor intensity of workers, minimizes the speed limitations of manual feeding, and matches the feeding rhythm with the continuous printing rhythm of the inkjet printer, thereby improving production efficiency.

[0038] The clamping and rotating structure 7 includes a power component mounted on the support frame 3. The power component is equipped with a first fixed seat 703 and a second fixed seat 706. The power component is used to drive the first fixed seat 703 and the second fixed seat 706 to move, so as to clamp or release the stainless steel thermos cup by the first fixed seat 703 and the second fixed seat 706. Both the first fixed seat 703 and the second fixed seat 706 are provided with inclined surfaces, and the first fixed seat 703 and the second fixed seat 706 are aligned above the center of the stainless steel thermos cup. This arrangement allows the stainless steel thermos cup to be lifted upward when the first fixed seat 703 and the second fixed seat 706 approach each other, so that the stainless steel thermos cup is separated from the inner wall of the slot 503. This arrangement ensures that the inner wall of the slot 503 will not interfere with the pattern printed on the stainless steel thermos cup during the printing and curing process. The power component includes two third support plates 701 that are bolted to the support frame 3. The top of each of the two third support plates 701 is bolted to a slide cylinder 702, and a mounting plate 708 is bolted to one of the slide cylinders 702. A support rod is welded to the side of the mounting plate 708 near the first fixed seat 703. The first fixed seat 703 is sleeved on the support rod. A bearing is provided at the connection between the outer surface of the support rod and the first fixed seat 703. The connection between the bearing, the support rod, and the first fixed seat 703 is an interference fit.

[0039] Another slide cylinder 702 is bolted to a second motor frame 704, and a second drive motor 705 is bolted to the second motor frame 704. A second fixed seat 706 is set on the output shaft of the second drive motor 705. The second fixed seat 706 and the output shaft of the second drive motor 705 are keyed together. The second fixed seat 706 is also provided with a threaded port 707, and a fastening bolt is threaded to the threaded port 707. The end of the fastening bolt abuts against the output shaft of the second drive motor 705. The second drive motor 705 can drive the second fixed seat 706 to rotate, thereby driving the stainless steel thermos cup to rotate.

[0040] The feed port 201, the print head 403, the first fixed seat 703, the second fixed seat 706, the UV curing lamp 601, and the conveyor 8 are all located on the rotation track of the turntable 501.

[0041] In this application, the control of each component relies on the existing PLC control system. The linear module 401, the inkjet head 403, the drive shaft 507, the slide cylinder 702, the second drive motor 705, the conveyor 8, the grating, and the audible and visual alarm 104 are all controlled by the PLC control system. The various sensors, solenoid valves, drivers, and circuit connections required for the operation of the PLC control system are all existing technologies. The specific circuit layout and program writing can be configured according to the actual equipment parameters. This is existing technology and will not be described in detail in this application. It should be noted that the stainless steel thermos cup is a cylindrical cup without a lid, and the end of the cup body away from the rim has an indentation. That is, the stainless steel thermos cup that can be processed in this application has a defined shape. For ease of understanding, this application uses A to represent the stainless steel thermos cup to be processed, and it is marked in the figure. The stainless steel thermos cup to be processed is placed in the hopper 2. When the area of ​​the turntable 501 other than the slot 503 is aligned with the discharge port 201, the turntable 501 will prevent the stainless steel thermos cup in the hopper 2 from being discharged from the discharge port 201. When the slot 503 is aligned with the discharge port 201, the stainless steel thermos cup is discharged from the discharge port 201 and enters the slot 503. The drive shaft 507 and the first drive motor 508 cooperate to drive the turntable 501 according to... Figure 3 The stainless steel thermos cup is rotated clockwise in the indicated direction, causing it to reach the clamping rotating structure 7. At this point, the turntable 501 stops rotating, and the two sliding cylinders 702 drive the first fixing seat 703 and the second fixing seat 706 to move closer together. The first fixing seat 703 is inserted into the recessed groove of the stainless steel thermos cup, while the second fixing seat 706 is inserted into the mouth of the stainless steel thermos cup to clamp and fix it. During this process, the stainless steel thermos cup moves slightly upward to disengage from the inner wall of the slot 503. Then, the second drive motor 705 drives the stainless steel thermos cup to rotate through the second fixing seat 706, while the linear module 4... 01 The printing head 403 is driven to move horizontally by the connecting frame 402. The printing head 403 prints on the stainless steel thermos cup. During the rotation of the stainless steel thermos cup, the UV curing lamp 601 cures the material printed by the printing head 403. After curing, the slide cylinder 702 drives the first fixed seat 703 and the second fixed seat 706 away from the stainless steel thermos cup to release the stainless steel thermos cup. The stainless steel thermos cup falls back into the slot 503. Then the turntable 501 continues to rotate clockwise. Finally, the processed stainless steel thermos cup falls onto the conveyor 8 and is transported to the outside by the conveyor 8.
