Description

Technical Field

[0001] This utility model relates to the technical field of printing press color units, and in particular to an ink cartridge structure that is easy to disassemble and position. Background Technology

[0002] In various printing machines such as offset printing and gravure printing, the ink supply system is one of the core components that ensures print quality. As a key component of the ink supply system, the ink fountain holder's main function is to accurately and stably support the ink fountain (or ink trough) and ensure a relatively accurate positional relationship between the ink fountain and the inking roller or anilox roller below (hereinafter referred to as "ink roller"), thereby controlling the transfer of ink volume.

[0003] In existing technical solutions, the connection between the ink reservoir and the printing press wall plate mainly takes the following two mainstream forms:

[0004] 1. Fixed Connection: The ink reservoir is rigidly fixed to the printing press wall panel directly with multiple bolts. While this structure is sturdy and reliable, the disassembly and installation process is extremely cumbersome when replacing the ink reservoir, cleaning the inside of the ink reservoir, or performing maintenance. Operators must use tools to loosen and tighten multiple bolts one by one, consuming a significant amount of time and manpower, severely impacting the printing press's efficiency and production continuity. Especially in printing jobs that require frequent ink color changes, the downtime costs caused by this fixed structure are unacceptable.

[0005] 2. Simple Detachable Connection: To address the inconvenience of disassembling fixed connections, some quick-release ink reservoir designs have emerged. These include simple pins, hooks, or single locking handles. While these designs simplify disassembly to some extent, they often suffer from the following inherent drawbacks: Lack of an effective pre-positioning mechanism: Each time the ink reservoir is disassembled and reinstalled, its relative position (such as gap and parallelism) with the ink roller changes slightly due to installation errors. Operators must spend considerable time fine-tuning to calibrate the gap between the ink reservoir lip and the ink roller surface to ensure consistent ink coverage across the entire print width. This adjustment process is highly dependent on the operator's experience and skill level, resulting in low efficiency and difficulty in guaranteeing consistent positioning after each installation, directly impacting print quality stability.

[0006] Existing quick-release structures may sacrifice the rigidity and stability of the connection. Under the vibration environment generated by the long-term high-speed operation of the printing press, such connections are prone to loosening or slight displacement, which can cause changes in the relative position of the ink reservoir and the ink roller, resulting in uneven ink supply, ink splatter, and other problems, seriously affecting print quality.

[0007] Therefore, existing ink reservoir structures cannot simultaneously meet the requirements of quick and convenient assembly / disassembly and precise and reliable positioning after installation. This has become a technical bottleneck restricting further improvements in printing press operating efficiency and print quality. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide an ink cartridge structure that is easy to disassemble and position.

[0009] To achieve the above objectives, this utility model discloses an ink cartridge structure that is easy to disassemble and position, including a frame, an ink roller, an ink trough seat, and a movable locking module. The ink trough seat is detachably mounted on the frame, and the ink roller is rotatably mounted on the frame and located at the ink outlet of the ink trough seat. The ink trough seat is used to supply ink to the surface of the ink roller.

[0010] The frame is provided with a first positioning block, the bottom of the ink tank is provided with a positioning groove and a locking position, the movable locking module includes a locking block, the locking block is circumferentially rotatably disposed on the frame, and the locking position is provided with a first locking arc surface.

[0011] The ink reservoir seat is nested on the first positioning block through the positioning groove, thereby positioning the ink reservoir seat in its original position on the frame. At the same time, the locking block is embedded in the locking position. Rotating the locking block so that its outer side abuts against the first locking arc surface locks the ink reservoir seat on the frame.

[0012] Furthermore, the first positioning block is adjacent to the ink roller, and the two sides of the first positioning block are respectively set as a first inclined surface and a second inclined surface. The shape of the positioning groove corresponds to the first positioning block. The positioning groove is nested on the first positioning block at a downward inclination. At the same time, the first inclined surface and the second inclined surface play a guiding role.

[0013] Furthermore, a pair of second positioning blocks are provided on the top of the frame, and the pair of second positioning blocks are symmetrically fixed on the top of the frame. A pair of lateral positioning slots are provided on the bottom of the ink trough seat. The second positioning blocks are used to support the lateral positioning slots, thereby limiting the ink trough seat between the pair of second positioning blocks and further restricting the swing amplitude of the ink trough seat.

[0014] Furthermore, the movable locking module also includes a locking handle and a compression spring. The locking handle is rotatably mounted on the frame, and its end is eccentrically fixedly connected to the locking block. The compression spring is mounted on the locking handle and abuts against the bottom of the frame.

[0015] Furthermore, the locking block is provided with a second locking arc surface, and the locking block is rotated so that the second locking arc surface is tangent to the first locking arc surface.

[0016] Furthermore, both the first locking arc surface and the second locking arc surface are inclined.

[0017] Furthermore, the top of the ink reservoir is provided with an ink supply recess facing downwards, and an ink guide plate is provided in the ink supply recess. The ink guide plate is inclined in the ink supply recess and the inclination direction of the ink guide plate is towards the ink roller. The higher end of the ink guide plate is fixedly connected to the ink reservoir by bolts, and the lower end of the ink guide plate serves as the ink outlet of the ink reservoir.

[0018] Furthermore, the ink reservoir is provided with a plurality of ink volume adjustment rods, which are respectively arranged at intervals along the width of the ink reservoir. The ink volume adjustment rods are threaded onto the ink reservoir, and their ends abut against the back of the lower end of the ink guide plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. Enables quick and easy disassembly of the ink reservoir. Through optimized mechanical structure design, operators can lock and release the ink without tools, greatly improving maintenance and ink replacement efficiency.

[0021] 2. It integrates a high-precision pre-positioning function to ensure that the ink reservoir can automatically return to the preset state of precise relative position with the ink roller after each installation, eliminating repeated adjustment steps and ensuring the consistency and stability of printing quality.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will be combined with... Figures 1-6 The accompanying drawings provide a further detailed description of this utility model.

[0029] Reference Figure 1 and Figure 2 As shown, an ink cartridge structure for easy disassembly and positioning includes a frame 1, an ink roller 2, an ink trough seat 3, and a movable locking module 4. The ink roller 2 is rotatably mounted on the frame 1. The connection structure between the ink roller 2 and the frame 1 in this embodiment is well-known in the art and will not be described further here. The ink trough seat 3 is detachably mounted on the top of the frame 1, and the ink roller 2 is located at the ink outlet of the ink trough seat 3. The ink trough seat 3 is used to supply ink to the outer periphery of the ink roller 2. The movable locking module 4 is mounted on the frame 1 to restrict the movable position of the ink trough seat 3 on the frame 1.

[0030] Combined Figure 3 As shown, a pair of first positioning blocks 11 and a pair of second positioning blocks 12 are provided on the top of the frame 1.

[0031] A pair of first positioning blocks 11 are symmetrically fixed on the top of the frame 1 and are adjacent to the ink roller 2.

[0032] Furthermore, a first inclined surface 111 is provided between the top of the first positioning block 11 and its right side, and a second inclined surface 112 is provided between the bottom of the first positioning block 11 and its left side. In this embodiment, the first inclined surface 111 and the second inclined surface 112 are parallel.

[0033] The bottom of the ink reservoir 3 is provided with a positioning groove 32 that mates with the first positioning block 11. In this embodiment, the shape of the positioning groove 32 corresponds to the outer contour of the first positioning block 11. When the positioning groove 32 is disassembled from the first positioning block 11, it is guided by the first inclined surface 111 and the second inclined surface 112.

[0034] Reference Figure 4 As shown, a pair of second positioning blocks 12 are symmetrically fixed on the top of the frame 1 along the width direction of the frame 1. A pair of lateral positioning slots 31 are provided at the bottom of the ink reservoir 3. In this embodiment, the shape of the lateral positioning slots 31 is a right angle that matches the second positioning blocks 12 in the vertical section.

[0035] In this embodiment, the second positioning block 12 and the first positioning block 11 work together to achieve the pre-positioning function when installing the ink trough seat 3 (ensuring that the relative position and distance between the ink trough seat 3 and the ink roller 2 are unique). When the ink trough seat 3 is installed each time, there is no need to perform repeated positioning, which greatly improves work efficiency.

[0036] Reference Figure 4As shown, the movable locking module 4 includes a locking block 41, a locking handle 42, and a compression spring 43. A locking position 33 is provided inwardly on the side of the ink trough seat 3 that is not adjacent to the ink roller 2, and the locking position 33 is connected to the bottom of the ink trough seat 3. A connecting through hole 13 is provided on the surface of the frame 1, and the connecting through hole 13 is vertically opposite to the locking position 33.

[0037] The locking block 41 is rotatably mounted above the frame 1, and is vertically aligned with the connecting through hole 13. Specifically, the end of the locking handle 42 passes through the connecting through hole 13 and is eccentrically fixedly connected to the bottom of the locking block 41. A compression spring 43 is sleeved on the outer periphery of the locking handle 42.

[0038] Furthermore, a first locking arc-shaped surface 331 is provided within the locking position 33, and the first locking arc-shaped surface 331 is opposite to the opening of the locking position 33. In this embodiment, the first locking arc-shaped surface 331 is inclined, and the inclination direction of the first locking arc-shaped surface 331 is towards the opening of the locking position 33;

[0039] The locking block 41 is provided with a second locking arc surface 411, which is inclined. Specifically, the second locking arc surface 411 is inclined downward from the top of the locking block 41.

[0040] In this embodiment, the outer contour dimension of the locking block 41 should be smaller than the outer contour dimension of the locking position 33 to prevent interference between the ink reservoir seat 3 and the locking block 41 when the ink reservoir seat 3 is removed from the frame.

[0041] Reference Figure 3 , Figure 5 As shown, when installing ink reservoir 3:

[0042] S1. Align the lateral positioning slot 31 with the second positioning block 12, tilt the ink trough seat 3, and place the lower end of the ink trough seat 3 adjacent to the ink roller 2 so that the longitudinal positioning slot is inserted into the first positioning block 11 in an inclined downward manner. Then, place the ink trough seat 3 flat on the frame 1.

[0043] S2. When the ink trough seat 3 is placed flat on the frame 1, the top and inner side of the second positioning block 12 are used to support the top and inner side of the lateral positioning through groove 31, thereby limiting the range of movement of the ink trough seat 3 in the width direction on the frame 1.

[0044] S3. When the ink reservoir 3 is placed flat on the frame 1, the locking block 41 is located in the locking position 33. At this time, rotate the locking handle 42 to make the second locking arc surface 411 on the locking block 41 abut against the first locking arc surface 331.

[0045] Reference Figure 4As shown, when disassembling the ink trough seat 3: rotate the locking handle 42 to move the second locking arc surface 411 away from the first locking arc surface 331, then lift the ink trough seat 3 upwards at an angle, so that the longitudinal positioning groove falls off the first positioning block 11 and pulls the ink trough seat 3 backwards away from the frame 1.

[0046] Compared with the prior art, the installation structure of the ink reservoir seat 3 in this embodiment has the following advantages: The ink reservoir seat 3 is pre-positioned by the first positioning block 11, ensuring accurate relative positioning between the locking block 41 and the locking position 33. Simultaneously, the mutual abutment of two inclined arc-shaped surfaces enables rapid positioning of the ink reservoir seat 3, creating a detachable connection between the ink reservoir seat 3 and the frame 1. This facilitates cleaning of the ink reservoir seat 3 and the ink roller 2. The overall structure is simple and easy to operate. Furthermore, based on the above advantages, this ink reservoir seat can be replaced between printing equipment with the same color group, greatly improving versatility, achieving equipment modularization, and effectively reducing maintenance and production costs.

[0047] Reference Figure 4 As shown, furthermore, an ink supply recess 34 is provided on the top of the ink trough seat 3, and the ink supply recess 34 is connected to the right side of the ink trough seat 3.

[0048] An ink guide plate 35 is provided within the ink supply recess 34. The ink guide plate 35 is inclined within the ink supply recess 34, with the inclination direction towards the ink roller 2. Specifically, the higher end of the ink guide plate 35 is fixedly connected to the ink reservoir seat 3 by bolts. When the ink reservoir seat 3 is in use, ink is delivered to the ink guide plate 35 via external equipment and flows to its lower end, transferring it to the outer periphery of the ink roller 2.

[0049] Furthermore, the ink reservoir 3 is provided with a plurality of ink volume adjusting rods 36, which are spaced apart along the width of the ink reservoir 3. This embodiment does not limit the number of ink volume adjusting rods 36. Specifically, an adjusting threaded hole 37 is provided on the left side of the ink reservoir 3. One end of the ink volume adjusting rod 36 passes through the adjusting threaded hole 37 and abuts against the back of the lower end of the ink guide plate 35. The outer periphery of the ink volume adjusting rod 36 is threadedly connected to the adjusting threaded hole 37.

[0050] In use, rotate the ink volume adjustment lever 36 to make it extend and retract towards the ink roller 2. During the movement of the ink volume adjustment lever 36, its end drives the lower end of the ink guide plate 35 to tilt upward or return downward (changing the tilt angle of the ink guide plate 35), thereby adjusting the gap between the lower end of the ink guide plate 35 and the outer periphery of the ink roller 2, and achieving the technical effect of ink volume adjustment.

[0051] Reference Figure 1As shown, the ink trough seat 3 has a clearance recess 38 on one side adjacent to the ink roller 2. By being positioned in the clearance recess 38, the outer periphery of one side of the ink roller 2 is positioned within the ink supply recess 34. In this embodiment, the outer contour of the clearance recess 38 corresponds to the outer contour of the ink roller 2. When the ink trough seat 3 is fixedly mounted on the frame 1, the clearance recess 38 abuts against the outer periphery of the ink roller 2.

[0052] Compared with the prior art, the ink volume adjustment structure of this embodiment has the advantages of simple structure and simple and quick adjustment method.

[0053] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They cannot be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit of the main technical solution of this utility model should be covered within the protection scope of this utility model.
