Description

Technical Field

[0001] This invention relates to the field of printing technology, and in particular to a method for printing transparent rotating bodies. Background Technology

[0002] In digital printing equipment for round can workpieces, the digital printhead is extremely expensive. Structurally, the printhead is usually placed above the workpiece, and the curing LED is installed below or on the side of the workpiece. Generally, a process of printing and curing at the same time is adopted.

[0003] When printing transparent rotating bodies, the ultraviolet rays emitted by the curing LED lamp can be reflected through the printing medium onto the printhead surface. The printhead will be directly irradiated by the curing lamp, causing damage to the printhead due to ink curing. This damage is irreparable and results in significant losses. In view of this, this solution proposes a transparent rotating body printing method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a transparent rotating body printing method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for printing a transparent rotating body, comprising the following steps:

[0006] S1, First, install the transparent printable body to be printed on the rotating device;

[0007] S2, Adjust the rotating device to clamp the transparent print body to be printed. At this time, the rotating device detects the transparent print body and sends a signal to the PLC controller.

[0008] S3, the PLC controller reduces the power of the curing LED to the minimum output state and starts the printing carriage to print on the surface of the transparent print body along the printing direction. During the printing process, the rotating device drives the transparent print body to rotate.

[0009] S4. After the printing carriage completes one printing route, it resets and triggers the protection switch. The protection switch sends the received trigger signal to the PLC controller. The PLC controller increases the power of the curing LED to the curing state. At this time, the rotating device drives the printed transparent print to continue rotating until the printed material on the surface of the transparent print is cured.

[0010] Preferably, the rotating device includes:

[0011] A supporting base plate is provided with a supporting tailstock at one end of the top of the supporting base plate. The curing LED light is located at the top of the supporting base plate and below the transparent printed body. A pushing mechanism is provided on one side of the supporting tailstock.

[0012] A rotary drive mechanism is disposed on the top of the support base plate and is symmetrical to the horizontal center of the support tailstock.

[0013] A rotating support mechanism is disposed on the top of the support tailstock. The rotating support mechanism is driven by opposing clamping with the rotating drive mechanism to drive the transparent printed body to rotate.

[0014] Preferably, a sliding guide rail is fixedly installed at the top of the support base plate, and the bottom of the support tail is slidably sleeved on the top of the sliding guide rail.

[0015] Preferably, the actuating mechanism includes:

[0016] A lead screw unit, wherein the lead screw unit is inserted and connected to one end of the support base plate;

[0017] An adjusting plate is slidably connected to the top of the supporting base plate. The bottom of the adjusting plate is threadedly connected to the output end of the lead screw unit. The adjusting plate is used to adjust the horizontal distance to the supporting tail seat through the threaded engagement with the lead screw unit. A top support cylinder is provided at the top of the adjusting plate. The output end of the top support cylinder is fixedly connected to one side of the supporting tail seat. The top support cylinder is used to push the supporting tail seat to move horizontally away from the adjusting plate.

[0018] Preferably, the support tailstock moves toward the rotary drive mechanism after being pushed by the top support cylinder, and drives the rotary support mechanism to move synchronously, thereby clamping and supporting the transparent printed body during the rotation process.

[0019] Preferably, the rotating support mechanism includes:

[0020] A detection switch is disposed on the top of the support tailstock and located on the side near the top support cylinder;

[0021] A central shaft, one end of which is inserted and connected to the top of the support tailstock;

[0022] A support member is fitted onto the other end of the central shaft, and the support member is pressed against one end of the transparent printed body.

[0023] Preferably, a linear bearing is sleeved on the top of the support tailstock, and the middle part of the linear bearing is sleeved with the central shaft at the insertion end of the support tailstock. A sensing plate is provided on the side of the linear bearing away from the central shaft. The sensing plate is pushed by the linear bearing to detect switch triggering. A reset spring is sleeved on the outer wall of the central shaft.

[0024] Preferably, the support member includes:

[0025] A rotating bearing is sleeved on the end of the central shaft away from the support tailstock, and a bearing sleeve is sleeved on the outer wall of the rotating bearing;

[0026] A tailstock clamp is fitted onto the outer wall of the bearing sleeve, and the side of the tailstock clamp away from the central axis is used for fitting the transparent printing body.

[0027] Preferably, the rotary drive mechanism includes:

[0028] The spindle box is fixedly installed on the top of the support base plate;

[0029] A workpiece head support fixture is drivenly connected to the output end of the spindle box, and the end of the workpiece head support fixture away from the spindle box is used for clamping the end of the transparent print body.

[0030] Preferably, the method for mounting the transparent printed body using the rotating device includes the following steps:

[0031] The first step is to clamp one end of the transparent printable body to be printed onto the workpiece head support fixture.

[0032] The second step is to drive the adjustment plate through the screw unit to move the support tailstock until the support tailstock moves the tailstock clamp to wrap around and fit the other end of the transparent printed body.

[0033] The third step is to activate the top support cylinder to push the support tailstock to move. Driven by the support tailstock, the tailstock clamp further clamps the transparent printed body. At the same time, the feedback force is transmitted to the central shaft, which causes the linear bearing to move the sensor plate and trigger the detection switch.

[0034] The fourth step is to start the spindle box, which drives the transparent printing body to rotate through the workpiece head support fixture.

[0035] The technical effects and advantages of this invention are as follows:

[0036] The printing carriage 18 of this invention automatically performs the printing task. At the same time, a PLC controller is used to adjust the power of the curing LED lamp during the printing process. When the workpiece triggers the printing stage, the PLC controller reduces the power of the curing LED lamp. After printing is completed, the printing carriage 18 returns to the safe position and triggers the protection switch. Then, the PLC controller automatically increases the power of the curing LED lamp and rotates the printed object until curing is complete. This cycle is repeated. In this way, through intelligent control, when printing transparent objects, the curing LED lamp will not penetrate to the print head of the printing carriage at high power, thus protecting the print head during the printing process.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0042] This invention provides, for example Figure 1-3 This illustrates a method for printing transparent rotating bodies;

[0043] Example 1: The printing method includes the following steps:

[0044] S1, First, the transparent print body 13 to be printed is installed at the rotating device. The rotating device is adjusted to clamp the transparent print body 13 to be printed and move the transparent print body 13 to the printing station.

[0045] S2, Adjust the rotating device so that the transparent printable body 13 to be printed is clamped. At this time, the rotating device detects the presence of the transparent printable body 13 and sends a signal to the PLC controller 17. After the rotating device completes clamping of the transparent printable body 13 to be printed, it will detect that the transparent printable body 13 is in place. At this time, the rotating device sends a printing start signal to the PLC controller 17. After receiving the start signal, the PLC controller 17 starts printing.

[0046] S3, PLC controller 17 reduces the power of the curing LED lamp 14 to the minimum output state and starts the printing carriage 18 to print on the surface of the transparent print body 13 along the printing direction. During the printing process, the rotating device drives the transparent print body 13 to rotate. The rotating device drives the rotation of the transparent print body 13 and the movement of the printing carriage 18 to uniformly print the printing medium on the surface of the transparent print body 13.

[0047] S4, after the printing carriage 18 completes one printing route, it resets and triggers the protection switch 19. The protection switch 19 sends the received trigger signal to the PLC controller 17. The PLC controller 17 increases the power of the curing LED lamp 14 to the curing state. At this time, the rotating device drives the printed transparent print body 13 to rotate continuously until the printed material on the surface of the transparent print body 13 is cured. When the curing LED lamp 14 is running at high power, it works in conjunction with the rotating device to rotate the printed transparent print body 13. Under the ultraviolet light of the curing LED lamp 14, the printing medium on the surface of the transparent print body 13 is cured.

[0048] It should be noted that after the transparent printable body 13 is loaded, the printing carriage 18 will automatically execute the printing task. At this time, the PLC controller 17 will automatically reduce the power of the curing LED 14. After printing is completed, the printing carriage 18 returns to the safe position and triggers the protection switch 19. Then, the PLC controller 17 will automatically increase the power of the curing LED 14 and rotate the transparent printable body 13 until curing is complete, and the cycle will repeat.

[0049] Example 2: The rotating device includes:

[0050] A support base plate 1 is provided with a support tail 4 at one end of the top of the support base plate 1. A curing LED light 14 is provided at the top of the support base plate 1 and below the transparent printed body 13. A pushing mechanism is provided on one side of the support tail 4.

[0051] Specifically, a sliding guide rail 101 is fixedly installed on the top of the support base plate 1, and the bottom of the support tail 4 is slidably sleeved on the top of the sliding guide rail 101. Through the restriction of the sliding guide rail 101, the support tail 4 can make stable horizontal linear movement at the top of the support base plate 1.

[0052] Specifically, the promoting organizations include:

[0053] Screw unit 2 is inserted and connected to one end of the support base plate 1;

[0054] Adjusting plate 3 is slidably connected to the top of the support base plate 1. The bottom of adjusting plate 3 is threadedly connected to the output end of the lead screw unit 2. Adjusting plate 3 is used to adjust the horizontal distance to the support tail seat 4 through the threaded engagement with lead screw unit 2. A top support cylinder 301 is provided at the top of adjusting plate 3. The output end of top support cylinder 301 is fixedly connected to one side of support tail seat 4. Top support cylinder 301 is used to push support tail seat 4 to move horizontally away from adjusting plate 3.

[0055] It should be noted that a sliding groove is provided at one end of the support base plate 1, and a protruding structure with a threaded through groove is provided at the bottom of the adjusting plate 3. The protruding structure is threaded onto the threaded end of the lead screw unit 2. When the lead screw unit 2 rotates, the threaded engagement occurs, thereby enabling the adjusting plate 3 to move horizontally.

[0056] After being pushed by the top support cylinder 301, the support tail 4 moves toward the direction of the rotary drive mechanism and drives the rotary support mechanism to move synchronously, clamping and supporting the transparent printed body 13 during the rotation process.

[0057] A rotary drive mechanism is located on the top of the support base plate 1 and is symmetrical about the horizontal center of the support tailstock 4.

[0058] A rotating support mechanism is located on top of the support tailstock 4. The rotating support mechanism is driven by opposing clamping with the rotating drive mechanism to rotate the transparent printed body 13.

[0059] Specifically, the rotating support mechanism includes:

[0060] The detection switch 5 is located on the top of the support tailstock 4 and on the side close to the top support cylinder 301.

[0061] The central shaft 9, one end of which is inserted and connected to the top of the support tail 4;

[0062] The support is fitted onto the other end of the central shaft 9, and the support is pressed against one end of the transparent printed body 13.

[0063] Furthermore, a linear bearing 7 is sleeved on the top of the support tailstock 4. The middle part of the linear bearing 7 is sleeved with the central shaft 9 at the insertion end on the top of the support tailstock 4. A sensing plate 6 is provided on the side of the linear bearing 7 away from the central shaft 9. The sensing plate 6 is pushed by the linear bearing 7 to detect the triggering of the switch 5. A reset spring 8 is sleeved on the outer wall of the central shaft 9.

[0064] It should be noted that the return spring 8 is supported between the central shaft 9 and the support tail 4. When the support tail 4 is moved to clamp the transparent print body 13, the central shaft 9 moves closer to the support tail 4 to compress the return spring 8. At the same time, the central shaft 9 passes through and supports the linear bearing 7, which causes the linear bearing 7 to drive the induction plate 6 to pass through and trigger the detection switch 5. At this time, the transparent print body 13 is clamped in place, and the detection switch 5 sends the detection position information to the PLC controller 17 to activate the entire device to start the printing work.

[0065] The support components include:

[0066] A rotating bearing 10 is sleeved on the end of the central shaft 9 away from the support tailstock 4, and a bearing sleeve 11 is sleeved on the outer wall of the rotating bearing 10.

[0067] Tailstock clamp 12 is sleeved on the outer wall of bearing sleeve 11. The side of tailstock clamp 12 away from the central axis 9 is used for sleeve on one side of transparent print body 13. With the support of rotating bearing 10, one end of transparent print body 13 can be rotated and clamped.

[0068] Specifically, the rotary drive mechanism includes:

[0069] The spindle box 16 is fixedly installed on the top of the support base plate 1;

[0070] The workpiece head support fixture 15 is connected to the output end of the spindle box 16. The end of the workpiece head support fixture 15 away from the spindle box 16 is used to clamp the end of the transparent printed body 13.

[0071] It should be noted that a drive structure is provided inside the spindle box 16. The output end of the drive structure drives the workpiece head support fixture 15 to rotate, so that the transparent print body 13 held between the workpiece head support fixture 15 and the tailstock fixture 12 can rotate under the drive of the workpiece head support fixture 15 to perform the rotation printing and curing operation.

[0072] Example 3: The method for installing the transparent printed body 13 using the rotating device includes the following steps:

[0073] The first step is to clamp one end of the transparent printable body 13 to be printed onto the workpiece head support fixture 15.

[0074] The second step is to drive the adjusting plate 3 through the lead screw unit 2 to move the support tailstock 4 until the support tailstock 4 drives the tailstock clamp 12 to wrap around and fit the other end of the transparent print body 13, clamping the transparent print body 13 to be printed between the workpiece head support clamp 15 and the tailstock clamp 12, so that the transparent print body 13 can rotate under the support of the workpiece head support clamp 15 and the tailstock clamp 12.

[0075] The third step is to start the top support cylinder 301 to push the support tail 4 to move. Under the drive of the support tail 4, the tail clamp 12 further clamps the transparent printed body 13. At the same time, the feedback force is transmitted to the central shaft 9, so that the linear bearing 7 drives the sensing plate 6 to move and triggers the detection switch 5.

[0076] Fourth step, the spindle box 16 is started, and the transparent printing body 13 is rotated by the workpiece head support fixture 15.

[0077] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
