Description

Technical Field

[0001] The utility model relates to the technical field of dyes, in particular to a dye mixing device. Background Art

[0002] When printing and dyeing, different primary color dyes and water need to be mixed and stirred to prepare dye solution; then the prepared dye solution is injected into the dye vat, and the cloth is placed in the dye vat for printing and dyeing.

[0003] The stirring and mixing of dyes mainly relies on the dye mixing device, which introduces dyes of different colors into the mixing box and mixes and stirs the dyes through the stirring element. Chinese patent (patent number CN220496198U) A dye mixing device includes a mixing box, a solid mixing chamber and a liquid mixing chamber are provided on the top of the mixing box, the solid mixing chamber is used to crush and mix solid dyes, and the liquid mixing chamber is used to mix liquid dyes; a first stirring mechanism is provided in the mixing box, and a lifting mechanism is provided on the first stirring mechanism. During the mixing process of the utility model, the lifting mechanism drives the first stirring element to move up and down to fully stir the entire dye in the mixing box, so that the dye is stirred more evenly and the stirring efficiency is higher.

[0004] However, the dye in the mixing box only rotates in one direction as the stirring element rotates, and the mixing efficiency is low; and some solid dye particles with larger mass sink to the bottom. Although the stirring element moves up and down, it cannot drive a large amount of lower liquid dye to flow upward, so that the liquid mixing concentration of the solid dye in the lower layer is much higher than the liquid mixing concentration of the solid dye in the upper layer, resulting in uneven dye mixing. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide a dye mixing device, which is conducive to the exchange of upper liquid dye and lower liquid dye and improves the mixing uniformity.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dye mixing device, comprising a support frame, a mixing box is rotatably mounted on the support frame, a stirring member for driving the dye to flow upward is installed in the mixing box, a first driving member for driving the stirring member to rotate is installed on the support frame, a second driving member for driving the mixing box to rotate is installed on the support frame, the rotation direction of the mixing box is opposite to the rotation direction of the stirring member, a spiral guide plate for guiding the dye to flow downward is fixedly mounted on the inner wall of the mixing box, the stirring member comprises a connecting rod, a stirring knife is fixedly mounted on the side surface of the connecting rod, and the side surface of the stirring knife forms an acute angle with the horizontal plane.

[0007] Furthermore, the first driving member includes a first driving motor fixedly mounted on the supporting frame, and an output shaft of the first driving motor is fixedly connected to the connecting rod.

[0008] Furthermore, the second driving member includes a gear ring fixedly mounted on the peripheral side of the mixing box, a gear meshing with the gear ring is mounted on the support frame, and a second driving motor driving the gear to rotate is mounted on the support frame.

[0009] Furthermore, there are multiple spiral guide plates, which are evenly distributed along the circumference of the mixing box.

[0010] Furthermore, a flow guide pipe is fixedly installed on the lower side of the mixing box.

[0011] Furthermore, an upper cover is rotatably disposed on the upper side of the mixing box, and the upper cover is provided with a through hole for the connecting rod to pass through.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when the first driving member drives the connecting rod to rotate, the second driving member also drives the mixing box to rotate. Because the rotation direction of the mixing box is opposite to the rotation direction of the stirring member, that is, opposite to the rotation direction of the stirring knife, the stirring knife rotates counterclockwise, driving the liquid dye near the stirring knife to rotate counterclockwise, and at the same time driving the liquid dye to flow upward. The liquid dye near the inner wall of the mixing box, because the mixing box drives the spiral guide plate to rotate, on the one hand, drives the liquid dye near the inner wall of the mixing box to rotate clockwise around the axis of the mixing box, and on the other hand, drives the liquid dye near the inner wall of the mixing box to flow downward, thereby accelerating the exchange rate between the upper liquid dye and the lower liquid dye in the mixing box, and further improving the mixing uniformity.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 and Figure 2 The present embodiment provides a dye mixing device, including a support frame 1, a mixing box 2 is rotatably mounted on the support frame 1, a stirring member 3 is mounted in the mixing box 2, a first driving member 41 for driving the stirring member 3 to rotate is mounted on the support frame 1, and a guide pipe 7 is fixedly mounted on the lower side of the mixing box 2. The dye (liquid or solid particles) to be mixed is poured into the mixing box 2, and then the stirring member 3 is driven to rotate by the first driving member 41 to stir and mix the dye in the mixing box 2. After the mixing is completed, the mixed dye is guided to the outside through the guide pipe 7 at the bottom of the mixing box 2.

[0019] However, during the mixing process, the dye that is solid particles will settle to the bottom of the mixing box 2 under the action of gravity. Although the dye in the mixing box 2 can be stirred by the stirring element 3, the stirring work of the general stirring element 3 only drives the liquid dye to rotate, and cannot achieve a large amount of exchange between the upper and lower layers of the liquid dye. As a result, the solid granular dye settled at the bottom of the mixing box 2 is difficult to mix with the upper liquid dye, resulting in uneven dye mixing.

[0020] See also Figure 2 and Figure 3 , in order to solve the above technical problems. The stirring member 3 includes a connecting rod 31, and a stirring blade 32 is fixedly installed on the side of the connecting rod 31. The side of the stirring blade 32 forms an acute angle with the horizontal plane. When the first driving member 41 drives the stirring member 3 to rotate, that is, drives the connecting rod 31 to rotate, the connecting rod 31 drives the stirring blade 32 to rotate, such as Figure 3 As shown, the stirring blade 32 is inclined, so that when the stirring blade 32 rotates counterclockwise around the axis of the connecting rod 31, the side of the stirring blade 32 will have an upward thrust on the liquid dye, thereby pushing the liquid dye in the lower layer to flow upward and mix with the upper liquid dye, making the liquid dye mixed more evenly.

[0021] However, during the flow of liquid dye, the stirring blade 32 is generally placed in the middle of the mixing box 2. The liquid dye stirring blade 32 rotates, so that under the action of centrifugal force, the particles with larger mass will move to the inner wall of the mixing box 2, so that the number of particles that sink to the bottom edge of the mixing box 2 will gradually increase, and the closer to the bottom edge of the mixing box 2, the more solid particles will settle.

[0022] See also Figure 2 and Figure 3 In order to solve the above technical problems, a second driving member 5 is installed on the support frame 1 to drive the mixing box 2 to rotate. The mixing box 2 rotates in the opposite direction to the stirring member 3. A spiral guide plate 6 is fixedly installed on the inner wall of the mixing box 2 to guide the dye to flow downward.

[0023] When the first driving member 41 drives the connecting rod 31 to rotate, the second driving member 5 also drives the mixing box 2 to rotate. Since the mixing box 2 rotates in the opposite direction to the stirring member 3, that is, in the opposite direction to the stirring blade 32, Figure 3 As shown, the stirring blade 32 rotates counterclockwise, driving the liquid dye near the stirring blade 32 to rotate counterclockwise, and at the same time driving the liquid dye to flow upward, while the liquid dye near the inner wall of the mixing box 2, because the mixing box 2 drives the spiral guide plate 6 to rotate (clockwise), thereby driving the liquid dye near the inner wall of the mixing box 2 to rotate clockwise around the axis of the mixing box 2 on the one hand, and driving the liquid dye near the inner wall of the mixing box 2 to flow downward on the other hand;

[0024] As a result, the liquid dye in the middle of the mixing box 2 rotates counterclockwise upward, and the liquid dye on the inner wall of the mixing box 2 rotates clockwise downward. The two liquids rotate in different directions in the horizontal direction, and the liquids collide, which intensifies the mixing rate. In the vertical direction, the liquid dye in the middle of the mixing box 2 flows upward, and the liquid dye on the inner wall of the mixing box flows downward, which accelerates the exchange rate between the upper liquid dye and the lower liquid dye in the mixing box 2, thereby further improving the mixing uniformity.

[0025] At the same time, under the guidance of the spiral guide plate 6, the liquid dye at the inner wall of the mixing box 2 flows downward along the inner wall of the mixing box 2, flushes the precipitated solid particles at the bottom edge of the mixing box 2, and drives the flow to the middle of the mixing box 2, thereby reducing the accumulation of sediment at the bottom edge of the mixing box 2.

[0026] See also Figure 1 and Figure 2 The first driving member 41 includes a first driving motor fixedly mounted on the support frame 1, and the output shaft of the first driving motor is fixedly connected to the connecting rod 31. The first driving motor rotates to drive the connecting rod 31 to rotate.

[0027] See also Figure 1 and Figure 2 The second driving member 5 includes a gear ring 51 fixedly mounted on the side of the mixing box 2, a gear 52 meshing with the gear ring 51 is mounted on the support frame 1, and a second driving motor 53 driving the gear 52 to rotate is mounted on the support frame 1. The second driving motor 53 rotates, driving the gear 52 to rotate, and the gear 52 rotates, driving the gear ring 51 to rotate. Since the gear ring 51 is fixedly connected to the mixing box 2, the mixing box 2 rotates along with the gear ring 51.

[0028] See also Figure 3 There are multiple spiral guide plates 6, which are evenly distributed along the circumference of the mixing box 2. This increases the influence of the spiral guide plates 6 on the liquid dye at the inner wall of the mixing box 2 and improves the mixing efficiency.

[0029] See also Figure 2 An upper cover 8 is rotatably arranged on the upper side of the mixing box 2, and a through hole 9 is provided on the upper cover 8 for the connecting rod 31 to pass through. The upper cover 8 is used to reduce the situation that the liquid dye splashes to the outside during the mixing process.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
