Description

Technical Field

[0001] This utility model relates to the technical field of doctor blade holders, specifically a doctor blade holder for printing presses. Background Technology

[0002] In a printing press, ink adheres to the ink roller for printing. At this time, a doctor blade is needed to scrape off the excess ink on the ink roller. Since there are many doctor blades, they need to be placed on corresponding racks.

[0003] To facilitate the placement of doctor blades, existing technologies have made numerous improvements to doctor blade placement racks for printing presses. For example, patent publication number CN214984184U discloses a doctor blade placement rack for printing presses, including a frame standing on the ground. Inside the frame, there is a flexible clamp for placing and fixing the doctor blade. Inside the flexible clamp, there are two symmetrically distributed top blocks that abut against the flexible clamp from the inside. In this invention, a cleaning assembly consisting of a mounting frame and a cleaning block is installed on one side of each of the two top blocks inside the flexible clamp. After the doctor blade is placed inside the flexible clamp, it pushes open the two cleaning blocks and enters the two cleaning blocks. The cleaning blocks can clean the surface of the downward-moving doctor blade, absorbing residual liquid on the surface of the doctor blade. This increases the contact effect and contact time between the cleaning block and the doctor blade surface, effectively reducing the amount of residual liquid on the surface of the doctor blade after placement, and improving the dryness and cleanliness of the doctor blade and the frame after placement.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents show that several doctor blades are arranged vertically within flexible clamps for storage. However, in reality, printing plants require a large number of doctor blades, necessitating a corresponding number of flexible clamps. If a large number of doctor blades need to be stored, the height or width of the frame needs to be increased, or more storage racks are required. Since doctor blades themselves have a certain weight, taller or wider frames make it difficult to load and unload them. Increasing the number of storage racks also increases the cost of storing doctor blades. Therefore, there is an urgent need in this field to improve the doctor blade storage rack for printing presses to overcome the shortcomings of the existing technology. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a printing press doctor blade holder that not only increases the number of doctor blades that can be placed, but also facilitates the handling of doctor blades and reduces the cost of placing doctor blades.

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1-7 A printing press scraper holder includes a circular support base 1. A first rotating shaft 2 is rotatably connected to the center of the upper surface of the support base 1. A lower support plate 3 is fixedly connected to the lower side of the first rotating shaft 2. An upper support plate 4 is fixedly connected to the upper side of the first rotating shaft 2. Several second rotating shafts 5 penetrating the upper support plate 4 are rotatably connected to the upper surface of the lower support plate 3. Two support plates 7 are fixedly connected to the side of each second rotating shaft 5. Several elastic clips 6 located between two support plates 7 are fixedly connected to the side of each second rotating shaft 5. The elastic clips 6 are elastic, and the opposite sides of adjacent elastic clips 6 are provided with arc-shaped protrusions 14.

[0031] In this embodiment, when several printing press blades need to be placed, the blades are inserted between two elastic clips 6. The elastic clips 6 are elastic and hold the blades. The side of the elastic clips 6 is provided with an arc-shaped protrusion 14, which limits the blade. When the blades need to be placed again, the corresponding elastic clips 6 are rotated to the front side by rotating the second rotating shaft 5, and the blades are inserted between the two elastic clips 6 again. When all the blades are placed between the elastic clips 6 on the side of one second rotating shaft 5, the first rotating shaft 2 rotates on the support base 1 by rotating the lower support plate 3 and the upper support plate 4, and the other second rotating shaft 5 is rotated to the front side, and the blades are placed again. The placed blades can be removed by rotating the first rotating shaft 2 or the second rotating shaft 5, which increases the number of blades that can be placed, facilitates the removal and placement of blades, and reduces the cost of placing blades.

[0032] Example 2

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 This embodiment includes the above embodiment, and further includes: a barrier 8 adapted to the support plate 7 is fixedly connected between the lower support plate 3 and the upper support plate 4, and a clearance opening 10 adapted to the spacing between the two elastic clips 6 is opened on the side of the barrier 8; a rotating block 9 is fixedly connected to the upper end of the second rotating shaft 5; a label part 11 is fixedly connected to the upper end of the second rotating shaft 5; and the label part 11 is adapted to the position and number of the elastic clips 6.

[0034] In this embodiment, the enclosure 8 is used to protect the scraper that has been placed for a long time. When the scraper is to be picked up or put down, the corresponding elastic clip 6 is rotated to the direction that matches the position of the relief opening 10 by rotating the rotating block 9. The label part 11 is used to stick a label that matches the size of the scraper placed in the elastic clip 6, so that the scraper that needs to be used can be found later.

[0035] Example 3

[0036] Please see Figure 1 , Figure 2 and Figure 7 This embodiment includes all the above embodiments, and further includes: annular arc grooves 12 are provided on the upper surface of the bearing base 1 and the lower surface of the lower bearing plate 3, and a number of balls 13 are provided in the arc grooves 12; a number of handles 15 are fixedly connected to the side of the upper bearing plate 4, and the number of handles 15 is adapted to the number of the second rotating shafts 5; and a number of casters 16 are fixedly installed on the lower surface of the bearing base 1.

[0037] In this embodiment, when the lower support plate 3 and the upper support plate 4 need to be rotated, the ball bearing 13 rolls in the arc groove 12 to reduce the coefficient of friction when the first rotating shaft 2 is rotated. When rotating, the handle 15 is held to facilitate the rotation of the lower support plate 3 and the upper support plate 4. At the same time, the position of the support base 1 can be moved by the universal wheel 16, which has a locking effect.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
