Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and in particular to a pigment stirring and conveying device for a printing press. Background Technology

[0002] In large pigment manufacturing plants, pigments obtained after a series of processes are stored in large storage tanks. When they need to be exported, they are transported to trucks or loaded into pigment bags by conveying equipment (usually screw conveyors) installed at the opening of the large storage tanks.

[0003] As storage tanks are used for a long time, their sealing performance will gradually decline, causing some of the pigment inside the tank to clump together due to moisture. This clump of pigment will affect the normal use of the product and is also unsightly.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages 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 for explaining the present utility model and are not intended to limit the present utility model.

[0018] See Figure 1 This utility model provides a printing press pigment stirring and conveying device, which includes a housing 1 and a spiral blade 2 rotatably installed inside the housing 1. The spiral blade can be a shafted spiral structure or a shaftless spiral structure. In this embodiment, the spiral blade 2 adopts a shafted spiral blade structure. Specifically, the spiral blade 2 is installed on a main shaft 5, which is driven by a rotary drive motor 6 to rotate. The rotary drive motor 6 is installed on the housing 1. The main shaft 5 and the rotary drive motor 6 can be connected by a coupling or by other structures (such as gear structures, etc.).

[0019] See Figure 2 and Figure 3 The inner end wall of the outer shell 1 near the discharge port 11 is provided with a material clamping structure. Simultaneously, a grinding layer 21 is provided on the helical surface of the spiral blade 2 located on this side. This grinding layer 21 can be installed by means of attachment, such as by welding a grinding disc onto the helical surface of the spiral blade 2, or a textured structure can be provided on the helical surface of the spiral blade 2, such as fine stripes or micro-protrusions to increase the roughness of the working surface. The material clamping structure includes a clamping plate 31 and several sets of supporting springs 32 for supporting the clamping plate 31. The support spring 32 provides a force to press the pressure plate 31 against the helical surface of the spiral blade 2; one end of the support spring 32 is connected to the pressure plate 31, and the other end is installed on the inner end side wall of the outer casing 1 near the discharge port 11; specifically in this example, the pressure plate 31 is an arc-shaped plate. By setting it to this structure, the working area of ​​the pressure plate 31 can be increased. The working surface of the pressure plate 31 is an inclined structure that cooperates with the helical surface of the spiral blade 2. This inclined structure can be a protrusion 32. The protrusion 32 can be integrally formed with the pressure plate 31 or detachably connected.

[0020] Preferably, the end of the support spring 32 is mounted on the inner end side wall of the outer shell 1 near the discharge port 11 via the mounting plate 4. The mounting plate 4 enables the detachable installation of the material pressing structure. The installation position of the pressing plate 31 and the mounting plate 4 is on the side where the material is conveyed inside the outer shell 1 (generally the lower side, because the material will adhere to the lower side of the outer shell 1 for conveying due to its own weight).

[0021] See Figure 4During operation, the rotating spiral blades 2, combined with the frictional resistance between the material (pigment) and the inner wall of the outer casing 1, drive the material from the inlet to the outlet 11. When the material moves close to the outlet 11, it is pressed against the spiral surface of the spiral blades 2 by the clamping plate 31. During the rotation of the spiral blades 2, the spiral surface of the spiral blades 2 and the clamping surface of the clamping plate 31 will undergo a "misalignment movement". This "misalignment movement" in conjunction with the grinding layer 21 of the spiral blades 2 achieves the grinding process of the material (pigment). To further explain, the grinding force of this grinding process is limited and is only suitable for grinding and dispersing material agglomerates.

[0022] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
