Description

Technical Field

[0001] This utility model relates to the field of printer tooling technology, and in particular to a cylindrical rotary printing tooling for a UV printer. Background Technology

[0002] When printing cylindrical products, UV printers require specialized tooling fixtures. These fixtures not only ensure printing accuracy but also guarantee the stable rotation of the cylinder during the printing process, thus achieving high-quality 360° rotation printing. The accuracy of the tooling fixtures directly affects the quality of the printed products; even slight errors can lead to defects in the printed products.

[0003] However, existing tooling fixtures have the following problems: when clamping cylindrical objects, it is inconvenient to align the objects with the center of the fixture, which makes it easy for the printed patterns on the surface of the objects to have defects during the rotary printing process, and may also collide with the printing equipment, reducing the service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where cylindrical objects are difficult to align with the center of the clamp, resulting in defects in the printed pattern on the surface of the object during rotary printing, and the object may also collide with the printing equipment, reducing its lifespan. Therefore, this invention proposes a cylindrical rotary printing fixture for a UV printer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cylindrical rotary printing fixture for a UV printer includes a frame, a connecting plate, and a base plate. The bottom of the frame is fixedly connected to the top of the connecting plate, and the top rear side of the base plate is fixedly connected to the bottom of the connecting plate. The frame is U-shaped, and a front groove is provided on the front side of the frame.

[0007] The moving mechanism is mounted on the frame to facilitate the clamping of items;

[0008] A clamping mechanism is installed on the moving mechanism to facilitate the precise clamping of items.

[0009] In one possible design, the moving mechanism includes a first motor, a bidirectional lead screw, and two moving plates. The two ends of the bidirectional lead screw are rotatably connected to the inner walls of the two sides of the same front groove, respectively. One side of the first motor is fixedly connected to one side of the frame by bolts. The output shaft of the first motor rotatably passes through one side of the frame and is fixedly connected to one end of the bidirectional lead screw. Both moving plates are threaded onto the same bidirectional lead screw.

[0010] In one possible design, the clamping mechanism includes two rotating blocks, two No. 3 motors, two clamping plates, multiple clamping frames, multiple sliding frames, and multiple sliding holes. A No. 1 ring and a No. 2 ring are fixedly connected to the front sides of the two moving plates, respectively. The two rotating blocks are slidably disposed on the inner walls of the No. 1 and No. 2 rings, respectively. One side of each of the two No. 3 motors is fixedly connected to the side of the two rotating blocks away from each other by bolts. The output shafts of the two No. 3 motors rotatably pass through the two rotating blocks and are fixedly connected to the side of the two clamping plates away from each other. Multiple sliding holes are respectively disposed on the two clamping plates. Multiple sliding frames are respectively fixedly disposed on the side of the two clamping plates away from each other. Multiple clamping frames are slidably connected to multiple sliding frames. One end of each clamping frame is fixedly connected to a sliding rod, and one end of each sliding rod is inserted into the interior of multiple sliding holes and slidably connected to the sliding holes.

[0011] In one possible design, a first connecting frame is fixedly connected to one side of the first ring, and a second motor is fixedly connected to one side of the first connecting frame by bolts. The output shaft of the second motor rotates through the first connecting frame and is fixedly connected to the second connecting frame. The second connecting frame is fixedly set on one side of the rotating block.

[0012] In one possible design, each of the multiple clamping frames has a movable slider fixedly connected to one side, and each of the two rotating blocks has multiple grooves adapted to the sliders on the side where they are close to each other. The multiple sliders are slidably connected to the multiple grooves respectively.

[0013] In one possible design, the base plate has multiple mounting holes for easy assembly and disassembly, and a controller is fixedly installed on the top of the frame.

[0014] In one possible design, each of the multiple clamping frames has a second soft pad on one side for clamping the item, and a first soft pad is fixedly provided on the side of the two clamping plates that are close to each other.

[0015] In one possible design, the same positioning rod is fixedly connected to the inner walls of both sides of the frame, and both of the movable plates are slidably sleeved on the same positioning rod.

[0016] In this application, when a cylindrical object needs to be clamped, motor number one is started. The output shaft of motor number one rotates, driving the bidirectional lead screw to rotate. Since both moving plates are threaded onto the same bidirectional lead screw, the rotation of the bidirectional lead screw causes the two moving plates to move in relative or opposite directions along the lead screw. When the two moving plates move to the appropriate position, the cylindrical object can be clamped. After clamping, the position of the cylindrical object needs to be adjusted so that the clamping point is located at the center of the clamping plate. At this time, motor number three can be started by the controller to drive the clamping plate to rotate, thereby pushing the clamping frame. Under the guidance of the sliding frame, the clamping frame finely adjusts the position of the cylindrical object until the position of the cylindrical object is... At the center of the clamping plate, when a cylindrical object needs to be rotated to meet the printing requirements of the UV printer, the second motor is activated. The output shaft of the second motor rotates, causing the second connecting frame to rotate. Since the second connecting frame is fixedly set on one side of the rotating block, the rotating block will also rotate around the central axis of the first ring. The rotation of the rotating block further drives the entire clamping mechanism to rotate, thereby realizing the rotation printing of the cylindrical object. At the same time, in order to ensure that the clamping frame does not rotate with the clamping plate when it rotates, one side of the clamping frame is fixed, and the connected slider is slidably connected to the groove opened on the rotating block. In this way, even if the clamping plate rotates, the clamping frame can remain stable, ensuring that the clamping and adjustment of the cylindrical object are not affected.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this utility model, the tooling achieves precise clamping and adjustment of cylindrical objects through the ingenious design of the moving mechanism and the clamping mechanism, thereby improving the printing accuracy and efficiency. The design of the sliding hole and the sliding frame allows the clamping frame to be finely adjusted under the guidance of the sliding frame, so that the cylindrical object is located at the center of the clamping plate, ensuring printing quality. It can also reduce the collision between the object and the printing equipment when the object rotates, thereby improving the versatility and flexibility of the tooling. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-4 A tooling includes a frame 2, a connecting plate 3, a base plate 4, a moving mechanism, and a clamping mechanism. The bottom of the frame 2 is fixedly connected to the top of the connecting plate 3, and the top rear side of the base plate 4 is fixedly connected to the bottom of the connecting plate 3. The frame 2 is U-shaped and has a front groove 7 on its front side.

[0027] The moving mechanism includes a primary motor 6, a bidirectional lead screw 8, and two moving plates 9. The two ends of the bidirectional lead screw 8 are rotatably connected to the inner walls of the two sides of the same front groove 7. One side of the primary motor 6 is fixedly connected to one side of the frame 2 by bolts. Its output shaft rotates through one side of the frame 2 and is fixedly connected to one end of the bidirectional lead screw 8. The two moving plates 9 are threaded onto the same bidirectional lead screw 8. Therefore, when the primary motor 6 is started, it can drive the bidirectional lead screw 8 to rotate, thereby driving the two moving plates 9 to move in relative or opposite directions along the bidirectional lead screw 8, so as to clamp the cylindrical object.

[0028] The clamping mechanism includes two rotating blocks 18, two No. 3 motors 17, two clamping plates 20, multiple clamping frames 19, multiple sliding frames 22, and multiple sliding holes 21. A No. 1 ring 10 and a No. 2 ring 11 are fixedly connected to the front sides of the two moving plates 9, respectively. The two rotating blocks 18 are slidably mounted on the inner walls of the No. 1 ring 10 and the No. 2 ring 11, respectively. One side of each of the two No. 3 motors 17 is fixedly connected to the side of the two rotating blocks 18 away from their respective sides by bolts. Their output shafts rotatably pass through the two rotating blocks 18 and are fixedly connected to the side of the two clamping plates 20 away from their respective sides. Therefore, starting the No. 3 motor 17 can drive the clamping plates 20 to rotate. Multiple sliding holes 21 are respectively set on two clamping plates 20, and multiple sliding frames 22 are respectively fixedly set on the opposite sides of the two clamping plates 20. Multiple clamping frames 19 are slidably connected to multiple sliding frames 22, and a sliding rod is fixedly connected to one end of each clamping frame 19. One end of these sliding rods is inserted into the interior of multiple sliding holes 21 and slidably connected to the sliding holes 21. In this way, the clamping frame 19 can be finely adjusted along the direction of the sliding hole 21 under the guidance of the sliding frame 22, so as to adjust the position of the cylindrical object, so that the clamping point of the cylindrical object is located at the center of the clamping plate 20, which is convenient for printing.

[0029] This application can be used in the field of printer tooling, or in other fields applicable to this application.

[0030] Example 2

[0031] refer to Figures 1-4 Based on Embodiment 1, an improved cylindrical rotary printing fixture for a UV printer includes:

[0032] A first connecting frame 14 is fixedly connected to one side of the first ring 10. A second motor 13 is fixedly connected to one side of the first connecting frame 14 by bolts. The output shaft of the second motor 13 rotates through the first connecting frame 14 and is fixedly connected to the second connecting frame 16. The second connecting frame 16 is fixedly set on one side of the rotating block 18. In this way, the start of the second motor 13 can drive the rotating block 18 to rotate around the central axis of the first ring 10, thereby driving the entire clamping mechanism to rotate to meet the printing needs of the UV printer.

[0033] Each of the multiple clamping frames 19 has a movable slider 23 fixedly connected to one side. Each of the two rotating blocks 18 has multiple grooves 24 that are adapted to the sliders 23 on the side that are close to each other. The multiple sliders 23 are slidably connected to the multiple grooves 24 respectively. This not only ensures the stability of the clamping frame 19 during the sliding process, but also prevents the clamping frame 19 from rotating with the clamping plate 20 when it rotates, thus ensuring the adjustment of the items by the clamping frame 19.

[0034] The base plate 4 has multiple mounting holes 5 for easy disassembly and assembly, so that the tooling can be fixed in a suitable position according to actual needs. The top of the frame 2 is fixedly equipped with a controller 1, which is used to control the start and stop of motor 6, motor 13 and motor 17, as well as adjust their speed and direction.

[0035] Each of the multiple clamping frames 19 has a second soft pad 25 on one side for clamping the item, and a first soft pad 15 is fixedly installed on the side of the two clamping plates 20 that are close to each other. The installation of these soft pads can not only increase the friction between the clamping mechanism and the item, preventing the item from sliding or rotating during the printing process, but also protect the surface of the item from damage.

[0036] The same positioning rod 12 is fixedly connected to the inner walls of both sides of the frame 2. Both moving plates 9 are slidably sleeved on the same positioning rod 12. This not only ensures the stability of the moving plates 9 during movement, but also prevents the moving plates 9 from rotating or shifting under the rotation of the bidirectional screw 8.

[0037] However, as is well known to those skilled in the art, the working principles and wiring methods of controller 1, motor 6, motor 13 and motor 17 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience. Motor 6, motor 13 and motor 17 are all connected to controller 1 through lines and are powered by an external power source.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
