Description

Technical Field

[0001] This application relates to the field of ink proofing machine technology, and more particularly to a gravure printing proofing machine. Background Technology

[0002] Gravure printing proofing machines are essential equipment in the printing industry, used to print samples before formal printing to verify patterns, colors, and print quality. Traditional gravure printing proofing machines typically consist of a frame and printing rollers mounted on it. The printing rollers are installed in fixed slots or mounting positions on the frame via bearings and bearing seats. In practical applications, because the printing rollers need frequent replacement or maintenance to adapt to different printing plates or cleaning requirements, the existing mounting structures for the printing rollers often suffer from inconvenient disassembly and cumbersome operation. Utility Model Content

[0003] To solve the above problems, this technical solution provides a gravure printing proofing machine.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A gravure printing proofing machine, including

[0006] A frame with mounting slots;

[0007] A printing roller is disposed on the mounting groove; the printing roller includes a roller body and a rotating shaft.

[0008] A disassembly mechanism is provided on the frame and allows the printing roller to be detachably connected to the frame;

[0009] The disassembly mechanism includes an adjusting seat that slides into the mounting groove and a support seat for supporting both ends of the printing roller. The adjusting seat is inserted into the mounting groove from the outside of the frame, and the support seat corresponds to and is connected to the adjusting seat from the inside of the frame.

[0010] As described above, a gravure printing proofing machine has a lower shaft seat on the support base and an upper shaft seat that cooperates with the lower shaft seat. Bearings are provided at both ends of the rotating shaft. The lower shaft seat and the upper shaft seat together clamp the bearings so that the printing roller can rotate.

[0011] As described above, in a gravure printing proofing machine, the adjusting seat includes a sliding part embedded in the mounting groove and a limiting part provided on the sliding part. After the adjusting seat is connected to the support seat, the limiting part and the support seat are respectively on both sides of the frame to restrict the sliding part in the mounting groove.

[0012] As described above, in a gravure printing proofing machine, one end of the adjusting seat is provided with an adjusting bolt that is threadedly engaged with it, and an adjusting nut that engages with the adjusting bolt. The adjusting nut is tightened toward the adjusting seat to restrict the rotation of the adjusting bolt. The adjusting bolt presses against one end of the mounting groove to adjust the position of the support seat in the mounting groove.

[0013] As described above, in a gravure printing proofing machine, the other end of the adjusting seat is provided with an insertion hole, and the disassembly mechanism further includes a fixed seat provided on the frame, a rotating seat hinged to the fixed seat, and a pin provided on the rotating seat. The adjusting bolt adjusts the position of the supporting seat so that the insertion hole is disengaged from or inserted into the pin.

[0014] In the gravure printing proofing machine described above, a spring is fitted onto the pin.

[0015] As described above, a gravure printing proofing machine has a rotating head on its frame, which is pivotally connected to the rotating shaft so that the two rotate synchronously.

[0016] The beneficial effects of this application are:

[0017] This utility model provides a gravure printing proofing machine. By setting up an independent disassembly mechanism and assembling the adjustment seat and support seat from the outside and inside of the frame respectively, the installation and disassembly of the printing roller does not require complicated tools or disassembly of a large number of other parts. This significantly improves the efficiency of replacing, cleaning or maintaining the printing roller and reduces equipment downtime. Attached Figure Description

[0020] Figure 2 for Figure 1 Internal structural cross-sectional view. Detailed Implementation

[0021] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] A gravure printing proofing machine, including

[0023] The frame 1 has a mounting slot 11 on it;

[0024] A printing roller 2 is disposed on the mounting groove 11; the printing roller 2 includes a roller body 21 and a rotating shaft 22.

[0025] A disassembly mechanism 3 is provided on the frame 1 and allows the printing roller 2 to be detachably connected to the frame 1;

[0026] The disassembly mechanism 3 includes an adjustment seat 31 that slides with the mounting groove 11 and a support seat 32 at both ends of the printing roller 2. The adjustment seat 31 is inserted into the mounting groove 11 from the outside of the frame 1, and the support seat 32 corresponds to and is connected to the adjustment seat 31 from the inside of the frame 1.

[0027] This utility model provides a gravure printing proofing machine. By setting up an independent disassembly mechanism and assembling the adjustment seat and support seat from the outside and inside of the frame respectively, the installation and disassembly of the printing roller does not require complicated tools or disassembly of a large number of other parts. This significantly improves the efficiency of replacing, cleaning or maintaining the printing roller and reduces equipment downtime.

[0028] In traditional structures, there is a trade-off between the installation stability and adjustment flexibility of printing rollers: to ensure printing accuracy, the printing rollers must be firmly mounted on the frame, but this limits their ability to be quickly disassembled and finely adjusted. The technical solution of this application achieves rapid, simple, and stable modular assembly and disassembly of the printing rollers. The sliding fit between the adjusting seat and the mounting groove provides precise guidance and initial support; the connection between the adjusting seat and the support seat from both sides of the frame forms a stable structure that "clamps" the frame, ensuring both overall rigidity and stability after installation, while allowing for easy disassembly from the outside, greatly improving maintenance efficiency and operability.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the support base 32 is provided with a lower shaft seat 321 and an upper shaft seat 322 that cooperates with the lower shaft seat 321. Bearings 23 are provided at both ends of the rotating shaft 22. The lower shaft seat 321 and the upper shaft seat 322 together clamp the bearings 23 for the printing roller 2 to rotate. By clamping the bearing-bearing rotating shaft with the cooperation of the upper and lower shaft seats, smooth and stable rotation of the printing roller is ensured, effectively reducing friction and vibration, thereby improving printing quality. At the same time, this split shaft seat design makes bearing replacement or lubrication more convenient, eliminating the need to remove the entire support base from the frame, further reducing maintenance costs and time.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the adjusting seat 31 includes a sliding part 311 embedded in the mounting groove 11 and a limiting part 312 provided on the sliding part 311. After the adjusting seat 31 is connected to the support seat 32, the limiting part 312 and the support seat 32 are respectively on both sides of the frame 1 to restrict the sliding part 311 in the mounting groove 11. This effectively prevents the adjusting seat from unexpectedly loosening or detaching in the mounting groove. The limiting part and the support seat form a "clamping" effect on both sides of the frame, firmly locking the adjusting seat in the mounting groove, ensuring that the entire disassembly mechanism will not shift due to vibration during the operation of the printing roller, greatly enhancing the reliability and operational stability of the equipment.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, one end of the adjusting seat 31 is provided with an adjusting bolt 33 that is threadedly engaged with it, and an adjusting nut 34 that engages with the adjusting bolt 33. The adjusting nut 34 is tightened toward the adjusting seat 31 to restrict the rotation of the adjusting bolt 33. The adjusting bolt 33 presses against one end of the mounting groove 11 to adjust the position of the support seat 32 in the mounting groove 11. This achieves precise and linear fine-tuning of the axial position of the printing roller. By tightening the adjusting bolt, the position of the entire adjusting seat (along with the printing roller on it) in the mounting groove can be precisely controlled, thereby enabling precise control of printing pressure or registration accuracy. After the adjusting nut is locked, it effectively prevents the bolt from loosening, ensuring that the adjusted position will not shift under high-speed printing conditions, thus guaranteeing the stability of printing quality.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the other end of the adjusting seat 31 is provided with a socket 35. The disassembly mechanism 3 also includes a fixed seat 36 mounted on the frame 1, a rotating seat 37 hinged to the fixed seat 36, and a pin 38 mounted on the rotating seat 37. The adjusting bolt 33 adjusts the position of the support seat 32 so that the socket 35 is disengaged from or engaged with the pin 38. After precise position adjustment is completed by adjusting the bolt, a simple flipping action allows the pin to be inserted into the socket, achieving quick and reliable locking of one end of the adjusting seat. Combined with the bolt pressing method at the other end, a dual fixing mechanism of one end tightening and the other end pin locking is formed, further enhancing the vibration resistance and stability of the equipment during operation. At the same time, the unlocking process is also simple, providing conditions for rapid disassembly.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, a spring 39 is fitted onto the pin 38. The spring force can automatically compensate for gaps caused by manufacturing tolerances or wear, ensuring that the pin always maintains tight contact with the socket and preventing shaking and abnormal noise. At the same time, it also provides a certain degree of cushioning, making the insertion and removal of the pin smoother and improving the reliability of locking.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the frame 1 is provided with a rotating head 12, which is pivotally connected to the rotating shaft 22 so that the two rotate synchronously. This allows adjustment of the rotational position of the roller body without contacting it, facilitating printing.

[0035] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
