Description

Technical Field

[0001] This utility model relates to the field of printing color matching technology, specifically to a color matching device for printing publications. Background Technology

[0002] Before printing begins, color mixing of pre-added pigments is a crucial step in ensuring accurate color reproduction in publications such as books, magazines, and posters. In traditional printing, this task has always relied on manual operation. Operators mix different inks or pigments one by one according to predetermined ratios, then stir them manually to complete the color mixing process. However, this purely manual operation mode is extremely time-consuming, labor-intensive, and inefficient.

[0003] With the continuous advancement of technology, color mixing devices have gradually replaced manual mixing. However, most color mixing devices currently on the market rely on stirring components to mix the ink or pigment in the container. Since inks and pigments are mostly viscous gels, relying solely on this stirring method not only requires a lot of time to achieve thorough mixing, but also makes it difficult for the ink or pigment in the upper and lower layers of the container to mix evenly. This easily leads to color differences after color mixing, seriously affecting the color quality of printed materials. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a color mixing device for publication printing, so as to solve the problem of low stirring efficiency of existing color mixing devices.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a color mixing device for printing publications, comprising: a color mixing barrel with a lid, wherein a stirring part is provided inside the color mixing barrel; a fixed frame rotatably mounted on a support, wherein the color mixing barrel is mounted on the fixed frame, and the fixed frame is driven to rotate by a synchronization mechanism; wherein the synchronization mechanism comprises a bevel gear set and a transmission set connected by a third rotating shaft, the bevel gear set being driven by a motor, so that the transmission set drives the stirring part to rotate synchronously with the rotation of the fixed frame.

[0006] Optionally, a first rotating shaft and a second rotating shaft are fixedly connected to both sides of the fixing frame, and both the first rotating shaft and the second rotating shaft are bearing connected to the bracket. The output shaft of the motor is fixedly connected to the first rotating shaft.

[0007] Optionally, the bevel gear set includes a first bevel gear and a second bevel gear that mesh with each other. A sleeve is fixed on the second bevel gear. The sleeve is fixed on the bracket and the first rotating shaft passes through the sleeve. The first bevel gear is fixed to one end of the third rotating shaft. The third rotating shaft is rotatably mounted on the fixed frame through a fixing block.

[0008] Optionally, the transmission assembly includes a first pulley and a second pulley connected by a transmission belt. The first pulley is fixed to the end of the third rotating shaft away from the bevel gear set, and the second pulley is rotatably mounted on the fixed frame and connected to the stirring part through a transmission rod.

[0009] Optionally, the second pulley has a notch, and several locking strips are fixed in the notch. The transmission rod is engaged in the locking strips through several grooves on it. The stirring part has a hexagonal groove, and the end of the transmission rod near the stirring part has a hexagonal part. The transmission rod passes through the bucket lid and is engaged in the hexagonal groove through the hexagonal part.

[0010] Optionally, the fixing frame is further provided with a fixing plate, which is located on the side of the fixing frame near the lid of the container. The fixing plate can abut against the color mixing container to fix the color mixing container inside the fixing frame.

[0011] Optionally, a threaded rod is rotatably connected to the fixed plate, the threaded rod passes through the fixed frame and is threadedly connected to it, and a crank is fixed to the end of the threaded rod away from the fixed plate.

[0012] Optionally, the fixed plate and the transmission rod are connected by bearings.

[0013] Optionally, the bucket lid and the color mixing bucket are connected by a bearing, and the bucket lid has a material inlet for feeding and discharging materials, and the material inlet is covered with a door.

[0014] Optionally, the motor is fixed to the base.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention uses a motor to drive a fixed frame to rotate on a support, so that the color mixing tank fixed on the fixed frame can be loaded with pigments or inks and rotate, so that the pigments or inks are evenly mixed together under the action of gravity, making the pigments or inks more uniformly mixed.

[0017] Meanwhile, this invention also uses a bevel gear set to transmit the motor driving force to the stirring part inside the color mixing tank through the transmission component. This allows the device to drive the stirring part to rotate synchronously while the color mixing tank is rotating. The combination of the two further improves the efficiency and uniformity of color mixing. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] As mentioned earlier, most color mixing devices on the market currently rely on stirring components to mix the ink or pigment in the container. Since inks and pigments are mostly viscous, gel-like substances, this stirring method alone not only requires a significant amount of time to achieve thorough mixing, but also makes it difficult for the upper and lower layers of ink or pigment to mix evenly, easily leading to color differences after mixing and severely affecting the color quality of printed materials. To address this, this invention provides a color mixing device for the publication printing field, solving the aforementioned problems. This invention solves the problem in the following way.

[0029] Example 1:

[0030] Please refer to the instruction manual appendix. Figures 1 to 6 As shown in the figure, this embodiment provides a color mixing device for publication printing. The device includes a color mixing tank 1, a fixing frame 2, a support 3, and a synchronization mechanism 6. The color mixing tank 1 has a lid 11, which is rotatably connected to the tank 1 in a non-detachable manner (e.g., by bearing connection). The lid 11 has a material inlet for feeding and discharging, and a door is fitted over the inlet. Through this door, the material inlet can be opened or closed to add or remove color ink or pigment.

[0031] A stirring section 12 is rotatably connected (e.g., via a bearing connection) inside the mixing tank 1. A hexagonal groove 121 is formed on the top of the stirring section 12 (the end facing the lid 11). A small opening is formed in the center of the lid 11, and the stirring section 12 is bearing-connected to this small opening, leaving the hexagonal groove 121 exposed outside. In use, a shaft conforming to the opening of the hexagonal groove 121 is inserted into it and rotated, which drives the stirring section 12 to rotate and stir within the mixing tank 1.

[0032] In this first embodiment, as Figure 1 or Figure 3As shown, the mounting bracket 2 has a top plate, a bottom plate, and two side plates, which are joined together to form a frame structure. A fixing plate 23 is located in the middle area between the top and bottom plates. Two threaded rods 25 are bearing-connected to the top surface of the fixing plate 23 (the surface closest to the top plate of the mounting bracket 2). A crank handle 24 is fixed to each threaded rod 25, and the threaded rod 25 passes through and is threaded onto the top plate of the mounting bracket 2. In use, the operator places the palette 1 on the bottom plate of the mounting bracket 2, then screws on the threaded rods 25, pushing the fixing plate 23 relative to the top plate of the mounting bracket 2 until the fixing plate 23 is firmly against the palette 1, thus fixing the palette 1 relative to the mounting bracket 2. To disassemble, the operation is reversed.

[0033] It should be noted that, in order to avoid unnecessary displacement of the paint bucket 1 during the rotation of the fixing frame 2, the lid 11 of the paint bucket 1 is designed to be lowered to a certain distance from the body of the paint bucket 1. That is to say, the plane on which the top surface of the lid 11 is located should be equal to or lower than the plane on which the edge of the paint bucket 1 is located. In this way, when the fixing plate 23 on the fixing frame 2 moves, the fixing plate 23 will abut against the edge of the paint bucket 1, and the relative rotation of the lid 11 will not affect the fixation of the paint bucket 1.

[0034] In this first embodiment, as Figure 1 As shown, a first rotating shaft 21 and a second rotating shaft 22 are respectively provided on both sides of the fixing frame 2. Both the first rotating shaft 21 and the second rotating shaft 22 are rotatably connected (e.g., by bearings) to the bracket 3. The output shaft of the motor 4 is fixedly connected to the first rotating shaft 21, and the motor 4 is fixed to the base 5. Therefore, when the motor 4 is powered on, its output shaft drives the first rotating shaft 21 to rotate, thereby causing the fixing frame 2 to rotate the color mixing tank 1 relative to the bracket 3. This allows the ink or pigment in the color mixing tank 1 to mix evenly under the action of gravity, avoiding color breaks or color differences caused by difficulty in mixing different layers.

[0035] In this first embodiment, as Figure 1 As shown, a synchronization mechanism 6 is also provided. The synchronization mechanism 6 includes a bevel gear set and a transmission set connected by a third rotating shaft 66. The transmission set connects the stirring section 12 and the third rotating shaft 66, and the bevel gear set is connected to the motor 4, used to transmit the power output from the motor 4 to the third rotating shaft 66, and then to the stirring section 12 via the transmission set. This allows the synchronization mechanism 6 to synchronously drive the stirring section 12 inside the mixing tank 1 to rotate simultaneously with the rotation of the aforementioned fixed frame 2 via the drive of the motor 4. This ensures that the ink or pigment is mixed evenly under the action of gravity while also being stirred by the stirring section 12, resulting in more thorough and efficient mixing.

[0036] Example 2:

[0037] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 1 or Figure 2 As shown, in this second embodiment, the bevel gear set includes a first bevel gear 67 and a second bevel gear 68 that mesh with each other. A sleeve 69 is fixed on the second bevel gear 68, and the sleeve 69 is fixed on the bracket 3, with the first rotating shaft 21 passing through the sleeve 69. The first bevel gear 67 is fixed to one end of a third rotating shaft 66, which is rotatably connected to a fixing block 65, which is fixed to the fixing frame 2. Therefore, when the first rotating shaft 21 drives the fixing frame 2 to rotate, the sleeve 69 and the second bevel gear 68 remain stationary. The third rotating shaft 66 rotates along with the fixing frame 2. During the rotation of the third rotating shaft 66, the position of the first bevel gear 67 changes. Since it meshes with the second bevel gear 68, the first bevel gear 67 rotates about the third rotating shaft 66 as its axis of rotation.

[0038] In this second embodiment, as Figure 1 As shown, the transmission assembly includes a first pulley 61 and a second pulley 62 connected by a transmission belt 64. The first pulley 61 is fixed on a third rotating shaft 66 and rotates along with the first bevel gear 67. The second pulley 62 is rotatably mounted on the fixed frame 2 and connected to the stirring unit 12 via a transmission rod 63. Therefore, when the first pulley 61 rotates, the second pulley 62 rotates along with it under the action of the transmission belt 64, thereby driving the transmission rod 63 and the stirring unit 12 to rotate. This allows the mixing tank 1 to rotate simultaneously with the stirring unit 12 inside the tank. This ensures that the ink or pigment is mixed evenly under the action of gravity while also being stirred by the stirring unit 12, resulting in more thorough and efficient mixing.

[0039] Example 3

[0040] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Three. For example... Figures 3 to 6 As shown, in this third embodiment, the second pulley 62 has a notch 621, and several retaining strips 622 are fixed inside the notch 621. The transmission rod 63 has a groove 631 corresponding to the retaining strips 622. The retaining strips 622 are engaged in the grooves 631, and the transmission rod 63 slides up and down within the notch 621. This allows the transmission rod 63 to rotate along with the second pulley 62. A hexagonal portion 632 is also fixed to the bottom end of the transmission rod 63 (i.e., the end near the stirring section 12). The hexagonal portion 632 of the transmission rod 63 passes through the lid 11 and engages with the hexagonal groove 121. This allows the stirring section 12 to rotate synchronously when the transmission rod 63 rotates. The transmission rod 63 is connected to the fixed plate 23 by a bearing.

[0041] Therefore, in this embodiment, the operator places the color mixing tank 1 on the fixed frame 2 as described in the previous embodiment. At this time, the transmission rod 63 and its hexagonal portion 632 are suspended above the hexagonal slot 121. Then, by turning the crank 24, the fixed plate 23 is driven to tightly abut against the color mixing tank 1. At this time, the transmission rod 63 moves with the movement of the fixed plate 23, and the hexagonal portion 632 is inserted into the hexagonal slot 121. Figure 5 or Figure 6 As shown, in Figure 6 In this state, part of the transmission rod 63 with grooves 631 is still located within the notch 621 of the second pulley 62. At this time, the second pulley 62 is rotated by the synchronization mechanism 6 in the manner described above, so that the transmission rod 63 rotates synchronously under the engaging action of the locking strip 622 and the grooves 631, ultimately driving the stirring part 12 to rotate. When it is necessary to remove the color mixing tank 1, the fixing plate 23 is operated in the opposite direction away from the color mixing tank 1. At this time, the hexagonal part 632 begins to gradually disengage from the hexagonal groove 121 until it is completely disengaged. After that, the operator can remove the color mixing tank 1 from the fixing frame 2.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
