Technical Field
[0001] This utility model relates to the field of environmentally friendly printing, and more specifically, to a pigment mixing device for environmentally friendly printed products. Background Technology
[0002] In the field of environmentally friendly printing, the performance of pigment mixing equipment directly affects the quality of printed materials and the sustainability of the production process. Since the beginning of the 21st century, with the development of industrial automation technology, the printing industry has begun to introduce automated mixing equipment.
[0003] A search revealed that Chinese Patent Publication No. CN222841972U discloses "a pigment mixing device, including a mixing box, a fixed frame fixedly connected to the top of the mixing box, a motor fixedly connected inside the fixed frame, a vertical rod fixedly connected to the bottom of the motor output shaft, multiple connecting rods fixedly connected to the outer wall of the vertical rod, multiple conical holes evenly opened on the outer wall of the multiple connecting rods, a scraper fixedly connected to the outer wall of two connecting rods, a feeding box fixedly connected to the outer wall of the mixing box, and a feeding pipe fixedly connected to the top of the feeding box. This utility model, by setting up a motor, vertical rod, connecting rods, conical holes, scraper, feeding box, feeding pipe, inclined filter screen and inclined plate, allows materials to enter the mixing box through the inclined filter screen and inclined plate, and the filter screen can be cleaned separately by opening the sealing door. At the same time, the liquid forms a turbulent phenomenon through multiple conical holes to avoid flow stripping phenomenon." However, the following defects still exist: The mixing method is simple, and the pigments mainly flow in one direction of rotation in the mixing box, making it difficult to form a complex multi-directional mixing flow field. Different pigment components cannot fully contact and blend with each other in the mixing box, resulting in uneven mixing. It takes a long time to achieve the ideal mixing effect, and the overall mixing efficiency is not high.
[0004] Therefore, we have made improvements to this and proposed an environmentally friendly pigment mixing device for printed products. Utility Model Content
[0005] The purpose of this invention is to address the problem of the current single stirring method and low mixing efficiency.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: An environmentally friendly pigment mixing device for printed products is proposed to improve the above-mentioned problems.
[0007] The specific details of this utility model are as follows: Includes a mixing tank, the interior of which is fixedly equipped with a stirring component for powerfully stirring pigments to promote mixing; The stirring assembly includes a servo motor fixedly mounted to the top of the mixing tank. A first bevel gear is fitted to the output end of the servo motor. The first bevel gear meshes with a second bevel gear and a third bevel gear. The third bevel gear is located above the second bevel gear. The second bevel gear passes through the mixing tank and extends into the interior of the mixing tank.

Both the stirring frame and the stirring blade are located inside the mixing tank.
[0008] As a preferred technical solution of this utility model, two sets of fixing rings are sleeved on the rotating shaft, and both sets of fixing rings are located inside the mixing barrel.

[0012] As a preferred technical solution of this utility model, the stirring blade is set at a slight inclination, the stirring frame is hexagonal in shape, and the arc-shaped cleaning plate is made of silicone.
[0013] As a preferred technical solution of this utility model, a filter plate is fixedly installed inside the feed pipe, and the filter plate and the feed pipe are fixedly connected by bolts.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the solution of this utility model: 1. With the set stirring components, during use, the servo motor drives the first bevel gear to rotate. The first bevel gear meshes with the second and third bevel gears respectively. When the first bevel gear rotates, it drives the second and third bevel gears to rotate in opposite directions. When the second bevel gear rotates, it drives the stirring frame to make a circular motion in the mixing tank.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0022] like Figure 1 As shown, this embodiment proposes an environmentally friendly printing product pigment mixing device, including a mixing tank 1, and a stirring component 2 for powerfully stirring pigments to promote mixing is fixedly installed inside the mixing tank 1. like Figure 3 , Figure 4 Figure 5As shown, the stirring assembly 2 includes a servo motor 201 fixedly mounted to the top of the mixing tank 1. A first bevel gear 202 is mounted on the output end of the servo motor 201. The first bevel gear 202 meshes with a second bevel gear 203 and a third bevel gear 204. The third bevel gear 204 is located above the second bevel gear 203. The second bevel gear 203 passes through the mixing tank 1 and extends into the interior of the mixing tank 1. A rotating shaft 205 is provided on one side of the second bevel gear 203. The rotating shaft 205 passes through the second bevel gear 203 and the third bevel gear 204 and is fixedly connected to the third bevel gear 204. A stirring frame 206 is provided at one end of the second bevel gear 203. A stirring blade 207 is fixedly connected to the rotating shaft 205. Both the stirring frame 206 and the stirring blade 207 are located inside the mixing tank 1. In use, the servo motor 201 drives the first bevel gear 202 to rotate. The first bevel gear 202 meshes with the second bevel gear 203 and the third bevel gear 204 respectively. When the first bevel gear 202 rotates, it will drive the second bevel gear 203 and the third bevel gear 204 to rotate in opposite directions. When the second bevel gear 203 rotates, it will drive the stirring frame 206 to make a circular motion in the mixing tank 1. When the third bevel gear 204 rotates, it will drive the rotating shaft 205 to rotate. At the same time, the stirring blade 207 rotates accordingly. The stirring frame 206 and the stirring blade 207 stir the pigment in opposite directions at the same time, which can more fully mix various pigment components and achieve the ideal mixing effect in a shorter time, significantly improving the efficiency of pigment mixing.
[0023] like Figure 3 and Figure 5As shown, two sets of fixing rings 3 are sleeved on the rotating shaft 205. Both sets of fixing rings 3 are located inside the mixing barrel 1. The stirring blade 207 is welded to the fixing rings 3. The stirring frame 206 is bolted to the second bevel gear 203. The inner sidewall of the stirring frame 206 is symmetrically provided with fixing blades 4. The stirring blades 207 and fixing blades 4 are staggered. The inner bottom wall of the mixing barrel 1 is bolted with a support column 5. The support column 5 passes through the bottom of the stirring frame 206 and is connected to the bearing of the stirring frame 206. The outer sidewall of the stirring frame 206 is bolted with an arc-shaped cleaning plate 6. The outer sidewall of the arc-shaped cleaning plate 6 is attached to the inner sidewall of the mixing barrel 1. During use, the stirring blades 207 and the fixed blades 4, which are symmetrically arranged on the inner wall of the stirring frame 206, are staggered. During the stirring process, the stirring blades 207 and the fixed blades 4 agitate the pigment from opposite directions. The stirring blades 207 rotate in a circular motion with the rotating shaft 205 to stir, while the fixed blades 4 move in a circular motion in another direction with the stirring frame 206 to stir, forming a complex multi-directional stirring flow field. This allows the pigment to be fully mixed in the mixing tank 1. The support column 5 bolted to the bottom wall of the mixing tank 1 provides stable support for the stirring frame 206, ensuring the smooth progress of the stirring process. At the same time, when the stirring frame 206 rotates, the arc-shaped cleaning plate 6 moves in a circular motion along the inner wall of the mixing tank 1, continuously scraping the tank wall and scraping off the pigment adhering to the tank wall, allowing it to re-participate in the mixing process.
[0024] like Figure 1 As shown, a feed pipe 7 is fixedly connected to the top of the mixing tank 1, and a discharge pipe 8 is fixedly connected to the side wall of the mixing tank 1. The inlet and outlet of both the feed pipe 7 and the discharge pipe 8 are controlled by valves. The operator can open the valve on the feed pipe 7 to add pigment into the mixing tank 1 through the feed pipe 7, and can open the valve on the discharge pipe 8 to discharge the well-mixed pigment.
[0025] like Figure 4 As shown, a spiral frame 9 is provided on one side of the first bevel gear 202. The spiral frame 9 is bolted to the top of the mixing tank 1 and is located on one side of the servo motor 201 and above the third bevel gear 204. The spiral frame 9 is connected to the first bevel gear 202, the second bevel gear 203, and the rotating shaft 205 through bearings. The spiral frame 9 provides stable support for the first bevel gear 202, the second bevel gear 203, and the rotating shaft 205.
[0026] like Figure 4 As shown, a control board 10 is fixedly installed on the top of the mixing tank 1, and the control board 10 is electrically connected to the servo motor 201. The operator can turn the servo motor 201 on or off through the control board 10, and can also adjust the speed of the servo motor 201 to facilitate the mixing and stirring of the pigments for environmentally friendly printing products.
[0027] like Figure 5As shown, the stirring blade 207 is slightly tilted, the stirring frame 206 is hexagonal, and the arc-shaped cleaning plate 6 is made of silicone. During the rotation of the tilted stirring blade 207 around its axis, the surface in contact with the pigment generates an oblique pushing force, causing the pigment to move in a circular motion in the horizontal direction as the stirring blade 207 rotates. It also produces a certain up-and-down tumbling effect in the vertical direction, promoting better mixing of the pigment. Due to the special hexagonal shape of the stirring frame 206, each side contacts the pigment in a different way and at a different angle during rotation, further enhancing the mixing effect of the pigment.
[0028] like Figure 4 As shown, a filter plate 11 is fixedly installed inside the feed pipe 7, and the filter plate 11 is fixedly connected to the feed pipe 7 by bolts. When the pigment enters the mixing tank 1 through the feed pipe 7, the filter plate 11 can effectively intercept impurities in the pigment, such as dust, fibers, and solid particles, preventing these impurities from entering the mixing tank 1.
[0029] Specifically, when using this environmentally friendly printing pigment mixing device: (e.g.) Figure 3 , Figure 4 Figure 5 As shown, the servo motor 201 drives the first bevel gear 202 to rotate. The first bevel gear 202 meshes with the second bevel gear 203 and the third bevel gear 204 respectively. When the first bevel gear 202 rotates, it drives the second bevel gear 203 and the third bevel gear 204 to rotate in opposite directions. When the second bevel gear 203 rotates, it drives the stirring frame 206 to make a circular motion in the mixing tank 1. When the third bevel gear 204 rotates, it drives the rotating shaft 205 to rotate. At the same time, the stirring blade 207 rotates accordingly. The stirring frame 206 and the stirring blade 207 stir the pigments in opposite directions, which can more thoroughly mix various pigment components and achieve the ideal mixing effect in a shorter time, significantly improving the efficiency of pigment mixing. The stirring blades 207 and the fixed blades 4, which are symmetrically arranged on the inner wall of the stirring frame 206, are staggered. During the stirring process, the stirring blades 207 and the fixed blades 4 agitate the pigment from opposite directions. The stirring blades 207 rotate in a circle with the rotating shaft 205 to stir, while the fixed blades 4 move in a circle in another direction with the stirring frame 206 to stir, forming a complex multi-directional stirring flow field. This allows the pigment to be fully mixed in the mixing tank 1. The support column 5 bolted to the bottom wall of the mixing tank 1 provides stable support for the stirring frame 206, ensuring the smooth progress of the stirring process. At the same time, when the stirring frame 206 rotates, the arc-shaped cleaning plate 6 moves in a circle along the inner wall of the mixing tank 1, constantly scraping the tank wall and scraping off the pigment adhering to the tank wall, allowing it to re-participate in the mixing process.
[0030] All technical features in this embodiment can be freely combined according to actual needs.
[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
