Description

Technical Field

[0001] This utility model relates to the field of ink printing technology, and in particular to an ink mixing and stirring device. Background Technology

[0002] Ink mixing is a key process in printing and coating production, and its uniformity directly affects the quality of the final product. Traditional ink mixing devices mostly use a single mixing structure, such as a straight arm or propeller mixer, which has problems such as many dead zones and low mixing efficiency. In addition, conventional equipment is difficult to clean and maintain, which affects production efficiency.

[0003] In existing technologies, some improvements attempt to enhance mixing by increasing the number of stirring stages or adjusting the rotation speed. However, when driven by multiple motors, the stirring trajectories tend to interfere with each other, thus reducing efficiency. Therefore, there is an urgent need for a stirring device that combines high-efficiency mixing capabilities, excellent sealing performance, and modular design to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an ink mixing and stirring device to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This application discloses an ink mixing and stirring device, including a stirring mechanism and a stirring support ring. The stirring mechanism is disposed on the stirring support ring. A wrapping plate is sealed and connected to both sides of the stirring support ring. The wrapping plate and the stirring support ring are combined to form a sealed stirring chamber. Each wrapping plate is provided with a plurality of support feet, and the support feet are detachably connected to the wrapping plate.

[0007] Preferably, the stirring mechanism includes a drive motor mounted on the stirring support ring, and the output end of the drive motor is poweredly connected to a first stirring rocker arm. The first stirring rocker arm is S-shaped and performs uniform mixing and stirring of the materials during rotation.

[0008] Preferably, the stirring mechanism further includes a second drive motor mounted on the stirring support ring. The output of the second drive motor is connected to a second stirring rocker arm, and the second stirring rocker arm cooperates with the first stirring rocker arm to perform mixing.

[0009] Preferably, the second stirring arm is C-shaped and is located around the first stirring arm. The movement trajectories of the two do not interfere with each other. The stirring direction of the second stirring arm can be either in the same direction as the first stirring arm or in the opposite direction.

[0010] Preferably, the second stirring arm is S-shaped and is located on one side of the first stirring arm, parallel to the first stirring arm. The side of the two arms that are close to each other guides the flow during the stirring process to increase the stirring effect.

[0011] Preferably, the distance between the first stirring arm and the second stirring arm is 0~3cm.

[0012] Preferably, the packaging plate has an opening, and a material cover is detachably connected to the opening, which seals the opening when connected to the opening.

[0013] Preferably, a sealing gasket is provided between the wrapping plate and the stirring support ring.

[0014] The beneficial effects of this utility model are:

Detailed Implementation

[0024] 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. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0025] See Figures 1-4 This utility model provides an ink mixing and stirring device, including a stirring support ring 2, a wrapping plate 3 and a stirring mechanism 1. The stirring support ring 2 is circular, and two drive motors (drive motor 104 and drive motor 207) are symmetrically installed on it. The wrapping plate 3 is fixedly connected to both sides by bolts.

[0026] The wrapping plate 3 is made of corrosion-resistant metal and includes two semi-circular plates. The edges are sealed to the stirring support ring 2. A silicone sealing gasket 201 is provided at the connection. Several support feet 301 are evenly distributed on the outside of the wrapping plate 3, including 4 to 8 feet. The support feet 301 are detachably connected to the wrapping plate 3 by bolts, and the height of the support feet 301 is adjustable within a range of ±5cm.

[0027] The stirring mechanism 1 includes a first stirring rocker arm 102 and a second stirring rocker arm 103. The first stirring rocker arm 102 is an S-shaped rocker arm and is driven by a drive motor 104.

[0028] The second stirring rocker arm 103 includes a C-shaped rocker arm, which is 1.2 times the length of the first stirring rocker arm 102. It is driven by a second drive motor 107. The distance between the two rocker arms is 0~5cm. The rotation can be controlled by the motor to achieve rotation in the same or opposite directions.

[0029] In one feasible embodiment, the second stirring arm 103 is an S-shaped rocker arm and is in close contact with the first stirring arm 102, and the two work together to stir and mix.

[0030] The output end of the drive motor 104 is connected to the output shaft 105, the first stirring rocker arm 102 is fixedly connected to the output shaft 105, and the bearing 108 is also connected to the output shaft, the bearing 108 is connected to the second stirring rocker arm 103.

[0031] The output end of the second drive motor 107 is connected to the second output shaft 106. The second stirring rocker arm 103 is fixedly connected to the second output shaft 106. The second bearing 109 is also connected to the output shaft. The second bearing 109 is connected to the first stirring rocker arm 102.

[0032] When one of the drive motors starts, it drives the corresponding stirring arm to rotate, thus initiating mixing. Subsequently, through the rotational connection of the bearings, it only supports the other stirring arm without generating power.

[0033] The top of the wrapping plate 3 has a circular opening, and the edge of the opening is fitted with a sealing gasket 201. It is sealed by a snap-on material cover 302. A transparent observation window is set in the center of the material cover 302 to facilitate monitoring of the stirring status.

[0034] Example 1:

[0035] The stirring chamber 101 has a diameter of 60cm. The first stirring arm 102 is S-shaped and 45cm long. The second stirring arm 103 is also S-shaped and 50cm long. The two arms are installed in parallel with a distance of 2cm between them. The drive motors 104 and 105 are both set to rotate in the same direction with a speed of 150r / min.

[0036] The parallel flow guiding effect of the double S-shaped rocker arms creates a mixing mode that combines laminar and turbulent flow.

[0037] Example 2:

[0038] The stirring chamber 101 has a diameter of 60cm. The first stirring rocker arm 102 is S-shaped and 40cm long. The second stirring rocker arm 103 is C-shaped and 55cm long. The C-shaped rocker arm is installed around the S-shaped rocker arm. The two rotate in opposite directions. The first drive motor is 104 at 150r / min and the second drive motor is 107 at 100r / min.

[0039] The C-shaped rocker arm expands the mixing range, and the reverse rotation enhances the shearing force, preventing materials from sticking together.

[0040] Example 3:

[0041] The stirring chamber 101 has a diameter of 60cm. The first stirring arm 102 is S-shaped and 45cm long. The second stirring arm 103 is also S-shaped and 50cm long. The two arms are installed in parallel with a distance of 2cm between them. The drive motors 104 and 105 rotate in opposite directions and have a rotation speed of 150r / min.

[0042] The double S-shaped rocker arms rotating in opposite directions enhance the shearing force, enabling high-intensity crushing and mixing of materials at the center.

[0043] III. Specific Usage Process

[0044] This utility model relates to an ink mixing and stirring device.

[0045] Open the material cover 302 and add ink raw materials, such as resin, pigment, and solvent, through the opening. The amount of material added should not exceed 80% of the volume of the mixing chamber 101. Then close the material cover 302 and tighten the buckle to ensure that the sealing ring is completely in place.

[0046] After stirring begins, the speed and direction of the two motors are set according to the viscosity of the ink; the power is turned on, and motor one and motor two drive the first stirring rocker arm 102 and the second stirring rocker arm 103 to start rotating, thereby stirring the material inside the stirring chamber 101, and the uniformity of mixing is monitored through the observation window.

[0047] The wear of the sealing gasket 201 needs to be checked regularly and replaced periodically to ensure a tight seal.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
