Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing equipment technology, specifically to a printing device that is easy to use for color matching. Background Technology
[0002] Color matching in printing equipment refers to the process of precisely matching the color of printed materials to the target color by adjusting the proportions of pigments, binders, and additives in the ink, or by controlling printing process parameters. The main purpose is not only to ensure that the ΔE value (color difference unit) between the printed material and the target color is less than the industry standard, thus avoiding defective products or rework due to color deviation, but also to prevent uneven color of printed materials caused by pigment sedimentation or layering through uniform ink mixing, which may result in white spots or white streaks during printing.
[0003] Traditional printing equipment often uses single-axis agitators during the color mixing and easing process to save costs. The agitator's movement trajectory is a fixed circle, which results in "dead zones" in ink mixing. For example, in high-viscosity inks (such as thick inks for screen printing), pigment particles tend to deposit at the bottom or edges of the container. Single-axis agitation requires a long time to achieve a uniform state. When color mixing, it is also necessary to move the color mixing container or agitator shaft to mix the "dead zones", which is quite inconvenient.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this invention is to provide a printing device that is easy to use for color matching, so as to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a printing device that is easy to use for color matching, including a box body, a horizontally arranged fixing plate one, and a horizontally arranged fixing plate two. The fixing plate one divides the interior of the box body into an installation cavity and a stirring cavity. The fixing plate two is fixed to the inner wall of the top of the box body. A driving mechanism is provided in the installation cavity inside the box body. The driving mechanism includes:
[0007] Two fixed columns are symmetrically arranged about the axis of the box and fixed to the second fixed plate. A driven gear is sleeved on the outer arc wall of the fixed column near the second fixed plate. The two driven gears mesh with each other and the meshing part is coaxial with the box. A vertical through-hole storage channel is opened on the side wall of the first fixed plate near the second fixed plate. The two fixed columns are located in the storage channel and the inner arc wall of the storage channel and the outer arc wall of the fixed column form an "8" shaped sliding path.
[0008] A limiting groove is provided on the outer edge of the side wall of the driven gear away from the second fixed plate. A limiting post is inserted in the groove. A horizontal guide block is fixed at the end of the limiting post away from the second fixed plate. A horizontal chuck is fixed at the end of the guide block away from the second fixed plate. A vertical stirring shaft is provided at the end of the chuck away from the guide block. The stirring shaft passes through the placement channel into the stirring chamber. The guide block and the chuck slide within the sliding path.
[0009] Furthermore, the guide block has a leaf-shaped horizontal cross-section. Slide grooves are provided on the inner arc wall of the storage channel and the outer arc wall of the fixed column, respectively, corresponding to the position of the chuck. The width of the slide groove is greater than the distance from the inner arc wall of the storage channel to the outer arc wall of the fixed column. The chuck slides in the slide groove. One of the driven gears meshes with a horizontal driving gear on one side along the horizontal direction. A fixed shaft is fixed to the top of the driving gear. The fixed shaft passes through the second fixed plate and the housing in sequence and is fixed to a motor. The motor is fixed to the outside of the housing. A fixed gear is coaxially fixed on the side wall of the fixed column away from the second fixed plate. The side of the outer arc wall of the two fixed gears that is close to each other is a smooth side, and the rest are provided with meshing teeth. A planetary gear is coaxially rotatably connected to the end of the chuck away from the guide block. A stirring shaft is fixed to the end of the planetary gear away from the chuck. The planetary gear is located outside the sliding path.
[0010] Furthermore, the planetary gear meshes with the fixed gear. The outer edge of the side wall of the driven gear away from the fixed plate has multiple limiting grooves arranged in a circular array about the axis of the driven gear, and the number of limiting grooves on the two driven gears is equal. When one of the limiting grooves on the two driven gears moves to the position where the two driven gears mesh with each other, the two limiting grooves can be spliced together to form a complete cylindrical groove. The cross-sectional radius of the chuck is larger than the cross-sectional radius of the planetary gear, and the cross-sectional radius of the planetary gear is larger than the cross-sectional radius of the stirring shaft. The outer arc wall of the stirring shaft away from the planetary gear has multiple stirring blades arranged in a circular array about the axis of the stirring shaft. The length of the stirring blades is less than the horizontal line segment distance between the axis of the fixed column and the axis of the stirring shaft.
[0011] Furthermore, a single fixing bolt is fixed through the side wall of the fixing plate 1, fixing plate 2, fixing column, and fixing gear that are close to each other. The fixing bolt is detachably connected to the inner wall of the top of the box. Fixing bolts are provided at the four corners of the side wall of the box, fixing plate 1, and fixing plate 2 that are close to each other. At least two fixing bolts are provided in a ring array about the fixing column about the axial direction of the fixing column on the side wall of the box, fixing plate 2, fixing column, and fixing gear. A feed inlet is provided at the top of the outer arc wall of the box, and a sealing cover is provided at the feed inlet. A discharge outlet is provided at the center of the bottom of the box, and a solenoid valve is installed at the discharge outlet.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The fixed column is driven by two meshing driven gears, which make the stirring shaft move in a figure-eight sliding path. This trajectory combines circular motion and axial oscillation, avoiding edge aggregation and covering most of the area in the stirring chamber. This greatly reduces the "dead zone" of traditional single-shaft stirring. At the same time, the meshing of the planetary gear and the fixed gear makes the stirring shaft move in the figure-eight path while intermittently reversing forward and reverse, thus forming turbulence. This helps to better break up pigment agglomerates, ensuring the uniformity of pigment mixing while improving efficiency.
[0014] 2. The drive mechanism adopts a modular design, which is convenient for disassembly and maintenance, and has a simple structure with easy-to-replace internal parts. Attached Figure Description

[0022] 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.
[0023] Please see the appendix Figure 1 To be continued Figure 4This utility model provides a printing device that facilitates color matching: it includes a housing 10, a horizontally arranged fixing plate 11, and a horizontally arranged fixing plate 12. The fixing plate 11 divides the interior of the housing 10 into an installation cavity and a stirring cavity. The fixing plate 12 is fixed to the inner wall of the top of the housing 10. A driving mechanism is provided in the installation cavity inside the housing 10. The driving mechanism includes:
[0024] Two fixed columns 13 are symmetrically arranged about the axis of the box 10 and fixed to the second fixed plate 12. A driven gear 20 is sleeved on the outer arc wall of the fixed column 13 near the second fixed plate 12. The two driven gears 20 mesh with each other and the meshing part is coaxial with the box 10. A vertical through-hole storage channel is opened on the side wall of the first fixed plate 11 near the second fixed plate 12. The two fixed columns 13 are located in the storage channel and the inner arc wall of the storage channel and the outer arc wall of the fixed column 13 form an "8" shaped sliding path.
[0025] A limiting groove 201 is provided on the outer edge of the side wall of the driven gear 20 away from the fixed plate 2 12. A limiting post 22 is inserted in the groove. A horizontal guide block 23 is fixed to one end of the limiting post 22 away from the fixed plate 2 12. A horizontal chuck 24 is fixed to one end of the guide block 23 away from the fixed plate 2 12. A vertical stirring shaft 26 is provided at one end of the chuck 24 away from the guide block 23. The stirring shaft 26 passes through the placement channel into the stirring chamber. The guide block 23 and the chuck 24 slide within the sliding path.
[0026] The guide block 23 has a leaf-shaped horizontal cross section. Slide grooves are provided on the inner arc wall of the storage channel and the outer arc wall of the fixing column 13, respectively, at the positions corresponding to the chuck 24. The width of the slide groove is greater than the distance from the inner arc wall of the storage channel to the outer arc wall of the fixing column 13. The chuck 24 slides in the slide groove.
[0027] One of the driven gears 20 is meshed with a horizontal driving gear 21 on one side along the horizontal direction. A fixed shaft is fixed to the top of the driving gear 21. The fixed shaft passes through the fixed plate 2 12 and the housing 10 in sequence and is fixed to a motor. The motor is fixed to the outside of the housing 10.
[0028] A fixed gear 14 is coaxially fixed on the side wall of the fixed column 13 away from the fixed plate 12. The side of the outer arc wall of the two fixed gears 14 that is close to each other is a smooth side, and the rest are provided with meshing teeth. A planetary gear 25 is coaxially rotatably connected to the end of the chuck 24 away from the guide block 23. A stirring shaft 26 is fixed to the end of the planetary gear 25 away from the chuck 24. The planetary gear 25 is located outside the sliding path.
[0029] It should be noted that: the driving gear 21 meshes horizontally with one of the driven gears 20, transmitting rotational power to the driven gear 20. The two driven gears 20 mesh with each other and the meshing point is coaxial with the housing 10, providing power drive for the figure-eight transmission. When the driving gear 21 drives one driven gear 20 to rotate clockwise, the other driven gear 20 rotates counterclockwise. When the limiting groove 201 on one of the driven gears 20 moves clockwise to the meshing point of the two driven gears 20, since the limiting grooves 201 on the two driven gears 20 are spliced together to form a circle, the limiting post 22 has the adjustment function of switching the limiting groove 201.
[0030] When the driven gear 20 rotates, the limiting groove 201 pushes the limiting post 22 to move circumferentially, which in turn drives the guide block 23 to move synchronously. The inner arc wall of the storage channel of the fixed plate 11 and the outer arc wall of the fixed post 13 form an "8" shaped sliding path. Due to the leaf-shaped structure of the guide block 23, when it slides on one side of the sliding path, the length direction of the guide block 23 is always flush with the circumferential tangent direction of the fixed post 13. And because it always slides against the inner wall of the sliding path, its orientation changes continuously. When the guide block 23 moves to the meshing point of the two driven gears 20, since there is no constraint in the middle of the sliding path, the guide block 23 is facing the sliding channel on the other side and can be easily guided to the other side. At this time, it is easy to be carried away by the limiting groove 201 on the other side and move to the other side, forming an "8" shaped movement trajectory.
[0031] The chuck 24 slides within the sliding path to prevent it from coming out.
[0032] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a technical solution: the planetary gear 25 meshes with the fixed gear 14, and the driven gear 20 is provided with a plurality of limiting grooves 201 arranged in a ring array about the axial direction of the driven gear 20 on the outer edge of the side wall away from the fixed plate 22, and the number of limiting grooves 201 on the two driven gears 20 is equal. When one of the limiting grooves 201 on the two driven gears 20 moves to the position where the two driven gears 20 mesh with each other, the two limiting grooves 201 can be spliced together to form a complete cylindrical groove.
[0033] The cross-sectional radius of the chuck 24 is greater than that of the planetary gear 25, and the cross-sectional radius of the planetary gear 25 is greater than that of the stirring shaft 26. The outer arc wall of the stirring shaft 26, away from the planetary gear 25, is provided with a plurality of stirring blades arranged in a ring array about the axial direction of the stirring shaft 26. The length of the stirring blades is less than the horizontal line segment distance between the axial direction of the fixed column 13 and the axis of the stirring shaft 26.
[0034] The same fixing bolt 101 is fixed through the side wall of the fixing plate 11, fixing plate 2, fixing column 13 and fixing gear 14 that are close to each other. The fixing bolt 101 is detachably connected to the inner wall of the top of the box 10. Fixing bolts 101 are provided at the four corners of the side wall of the box 10, fixing plate 11 and fixing plate 2 12 that are close to each other. At least two fixing bolts 101 are arranged in a ring array about the fixing column 13 about the axial direction of the fixing column 13 on the side wall of the box 10, fixing plate 2 12, fixing column 13 and fixing gear 14 that are close to each other.
[0035] The top of the outer arc wall of the box 10 is provided with a feed inlet, and a sealing cover is provided at the feed inlet. The bottom center of the box 10 is provided with a discharge outlet, and a solenoid valve is installed at the discharge outlet.
[0036] It should be noted that when the planetary gear 25 rotates around the fixed column 13, the planetary gear 25 will mesh with the fixed gear 14. Since the fixed column 13 and the fixed gear 14 are fixed on the fixed plate 12, the planetary gear 25 will rotate, which will drive the stirring shaft 26 to rotate. Similarly, when the planetary gear 25 moves to the meshing point of the two driven gears 20, the planetary gear 25 will no longer mesh with either of the fixed gears 14. Only when the limiting column 22 switches the position of the limiting groove 201 will the planetary gear 25 re-enter the motion track and mesh with the fixed gear 14 on the other side. It can be understood that at this time the planetary gear 25 rotates in the opposite direction, thereby realizing the intermittent forward and reverse stirring of the stirring shaft 26, further strengthening the shearing force, and making it easier to drive the pigment blocks at the edge to be added to the stirring of the central area.
[0037] The discharge port at the bottom of the housing 10 directly supplies ink to the printing equipment or is used to test the mixing effect. The fixing bolt 101 facilitates the disassembly and installation of the drive mechanism and the disassembly of various components.
[0038] Working principle:
[0039] The motor drives the active gear 21 to rotate, which in turn drives the driven gear 20 that meshes with it to rotate. Since the two driven gears 20 mesh with each other, reverse transmission is achieved. The limiting groove 201 on the driven gear 20 pushes the limiting post 22, which in turn drives the guide block 23 and the chuck 24 to move along the figure-eight sliding path of the fixed plate 11.
[0040] The planetary gear 25 intermittently meshes with the fixed gear 14 on the fixed column 13 during its movement, causing the planetary gear 25 to rotate and drive the stirring shaft 26 to intermittently rotate in both directions. The stirring blades on the stirring shaft 26 enhance the shearing and mixing of the ink under the combined motion of revolution (along a figure-eight path) and rotation (forward and reverse rotation), breaking up pigment agglomerates. The mixed ink is discharged from the discharge port at the bottom of the housing 10 to supply ink to the printing equipment or for testing. The fixing bolt 101 facilitates the disassembly and maintenance of various parts of the equipment.
