[0029] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] A LED lamp group support device for a printing machine, the structure of which can be Figure 1-Figure 5 In this embodiment, the LED light group support device for a printing press includes a fixed frame and two lifting assemblies. The fixed frame is used to accommodate the LED light group 6, making it convenient for workers to install the LED light group 6 on the printing press. The lifting assemblies are used to achieve the assembly between the device and the printing press and drive the fixed frame to move up and down according to actual work needs.

[0032] Specifically, such as Figure 1 and Figure 2As shown, the two lifting assemblies in this device should be installed on both sides of the material conveyor belt of the printing press, and a material channel is formed between the two lifting assemblies. The fixed frame is adjustable and is set on the top of the lifting assembly. The fixed frame is also provided with an installation channel for accommodating the LED light group 6, and the installation channel is connected to the material channel. After the device is assembled with the printing press, the light emitted by the LED light group 6 can be directed along the installation channel and the material channel toward the material conveyor belt of the printing press. When the product with the printed pattern passes under the LED light group 6 as the material conveyor belt moves, the light emitted by the LED light group 6 can quickly solidify the UV ink in the printed pattern, thereby preventing the pattern from being damaged in subsequent processes and improving the quality of the printed pattern.

[0033] In order to prevent the LED light group 6 and the fixing frame from obstructing the removal and replacement of the ribs transported across the bridge, the lifting assembly in this embodiment includes a connecting seat and a supporting bar 2, and the supporting bar 2 is arranged above the connecting seat in a liftable manner. Accordingly, in order to facilitate the restriction of the relative position of the fixing frame and the lifting assembly, a detachable positioning column is provided at the bottom of the fixing frame, a sliding cutout 21 for accommodating the positioning column is provided on the supporting bar 2, and a positioning hole group is provided on the connecting seat, and the positioning hole group is arranged directly below the sliding cutout 21. Figure 3 and Figure 5 As shown, the length direction of the sliding cutout 21 is parallel to the length direction of the supporting bar 2 , the positioning hole group includes a plurality of positioning holes 111 for accommodating positioning posts, and the plurality of positioning holes 111 are arranged along the length direction of the sliding cutout 21 .

[0034] When the printing press is in normal working condition, the structure of this device can be Figure 1 At this time, the bottom end of the positioning column will be inserted into the positioning hole 111 due to the descent of the supporting bar 2, thereby preventing the fixing frame from moving abnormally during normal operation and ensuring that the light generated by the LED light group 6 accurately illuminates the material conveyor belt of the printing press. When the bridge conveyor ribs of the printing press need to be disassembled and replaced due to product specification adjustment, the staff can drive the supporting bar 2 to move upward so that the device enters the position as shown in the figure. Figure 2 The state shown. At this point, the bottom of the fixing frame will be significantly spaced from the material conveyor belt of the printing press due to the rise of the support bar 2, and the bottom end of the positioning post will be disengaged from the positioning hole 111. The operator can then drive the fixing frame to slide along the length of the sliding notch 21, thereby providing ample operating space for replacing the ribs conveying bridge and facilitating the disassembly and assembly of the ribs conveying bridge.

[0035] Correspondingly, since the positioning hole group includes multiple positioning holes 111, the staff can also adjust the position of the fixing frame according to actual needs, so that the positioning column at the bottom of the fixing frame is inserted into different positioning holes 111 after the supporting bar 2 is lowered, thereby reducing the difficulty of adjusting the position of the LED lamp group 6 and facilitating meeting different work requirements.

[0036] To realize the assembly between the lifting component and the printing press, such as Figure 5 As shown, the connecting base may include a carrier plate 11 and a connecting plate 12, wherein the carrier plate 11 is arranged on top of the connecting plate 12 and is perpendicular to the connecting plate 12. The connecting plate 12 is provided with an assembly hole 121, and a positioning hole group is provided on the carrier plate 11. When assembling the device with the printing press, the staff can first insert the connecting bolt into the assembly hole 121, and then screw the connecting bolt into the preset screw hole on the printing press, thereby reliably fixing the connecting base to the printing press.

[0037] Accordingly, to achieve the lifting and lowering of the support bar 2, the lifting assembly in this embodiment may further include a drive cylinder 5. During assembly, the drive cylinder 5 should be mounted on the connecting seat, and the telescopic rod of the drive cylinder 5 should be connected to the support bar 2. Thus, the extension and contraction of the telescopic rod of the drive cylinder 5 drive the support bar 2 to move up and down.

[0038] In addition, the device may also be provided with a guide rod 22 on the bottom surface of the support bar 2, and a guide hole 112 is provided on the connecting seat for accommodating the guide rod 22. When the support bar 2 is raised or lowered, the guide rod 22 slides within the guide hole 112. At this time, the cooperation between the guide rod 22 and the guide hole 112 can improve the movement stability of the support bar 2 and prevent abnormal shaking of the support bar 2 during the raising or lowering process.

[0039] Optional, such as Figure 4 As shown, in this embodiment, the positioning column may include a threaded section 41, a connecting section 42, and a positioning section 43 connected in sequence from top to bottom. In order to achieve a detachable connection between the positioning column and the fixing frame, a threaded hole for accommodating the threaded section 41 is provided on the bottom surface of the fixing frame. At the same time, in order to prevent the positioning column from separating from the support bar 2 during use, the outer diameter of the connecting section 42 should be equal to the inner diameter of the sliding cutout 21, the outer diameter of the positioning section 43 should be larger than the outer diameter of the connecting section 42, and the inner diameter of the positioning hole 111 should be equal to the outer diameter of the positioning section 43. During assembly, the staff can pass the positioning column from bottom to top through the sliding cutout 21 to facilitate the insertion of the threaded section 41 into the threaded hole. Since the outer diameter of the positioning section 43 is larger than the outer diameter of the connecting section 42, after the assembly between the positioning column and the fixing frame is completed, the top surface of the positioning section 43 will contact the bottom surface of the support bar 2 to prevent the fixing frame from separating from the support bar 2.

[0040] Furthermore, to reduce the difficulty of inserting the positioning section 43 into the positioning hole 111, a guide cone surface can be provided at the bottom end of the positioning section 43. When there is a slight misalignment between the positioning section 43 and the positioning hole 111, the guide cone surface can guide the positioning section 43, so that the positioning section 43 can be smoothly inserted into the positioning hole 111 during the lowering process of the support bar 2.

[0041] Since the LED light group 6 in the prior art is generally installed on the printing press by bolt connection, it is difficult to disassemble and assemble the LED light group 6 when it is necessary to repair or replace the LED light group 6. To solve this problem, the fixing frame in this embodiment may include two fixing bars 31 arranged parallel to each other, and the two fixing bars 31 are connected by two connecting rods 32, so that the fixing bars 31 and the connecting rods 32 form the installation channel. In addition, a fixing groove 311 for accommodating the frame of the LED light group 6 is provided on the top surface of each fixing bar 31. When in use, the staff can install the LED light group 6 into the installation channel and place the frame of the LED light group 6 into the fixing groove 311, thereby completing the rapid assembly between the LED light group 6 and the fixing frame.

[0042] Accordingly, in order to prevent the LED lamp group 6 from being separated from the fixing frame, the fixing frame may further include a limit block 33. Figure 4 As shown, the stop block 33 is slidably disposed in the fixing groove 311, and a blocking piece 331 is provided on the top surface of the stop block 33. After the frame of the LED light assembly 6 is placed in the fixing groove 311, the operator can drive the stop block 33 to slide toward the LED light assembly 6, thereby clamping and securing the LED light assembly 6 with the help of the stop block 33 and the inner wall of the fixing groove 311. Since the blocking piece 331 is provided on the top surface of the stop block 33, after the LED light assembly 6 is clamped, the blocking piece 331 can also block the top surface of the LED light assembly 6, thereby further improving the installation reliability of the LED light assembly 6.

[0043] Optionally, to facilitate the sliding of the limit block 33, an adjustment screw hole 313 may be provided on the end surface of the fixing bar 31, and an adjustment screw 34 may be provided inside the adjustment screw hole 313. One end of the adjustment screw 34 should be rotatably connected to the limit block 33, and the other end is provided with an operating handwheel 341. When it is necessary to drive the limit block 33 to slide, the staff can apply a rotational torque to the adjustment screw hole 313 by operating the handwheel 341, thereby flexibly adjusting the position of the limit block 33 inside the fixing groove 311 with the help of the cooperation between the adjustment screw 34 and the adjustment screw hole 313, so as to quickly complete the installation and removal of the LED lamp group 6.

[0044] In addition, in order to improve the movement accuracy of the limit block 33 inside the fixed groove 311, a guide bar 332 can be provided on the bottom surface of the limit block 33, and a guide groove 312 for accommodating the guide bar 332 is provided on the bottom surface of the fixed groove 311, so that the movement of the limit block 33 can be guided by the cooperation of the guide bar 332 and the guide groove 312, and the limit block 33 can be prevented from rotating inside the fixed groove 311.

[0045] The following describes the effects of the above scheme:

[0046] This embodiment provides an LED light group support device for a printing machine, which can drive the fixed frame to move up and down through the support bar, and can drive the fixed frame to slide along the length direction of the sliding cutout, thereby providing sufficient operating space for the replacement of the ribs transported across the bridge, and improving the replacement efficiency of the ribs transported across the bridge. Secondly, this device can adjust the position of the fixed frame according to actual needs, and insert the bottom end of the positioning column into the corresponding positioning hole, thereby reducing the difficulty of adjusting the position of the LED light group. In addition, this device is provided with a sliding limit block on the fixed frame, and the staff can quickly disassemble and assemble the LED light group by sliding the limit block, thereby improving the operational convenience of the staff.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
