Description

Technical Field

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

[0002] Ink is an essential material used in printing, which transfers patterns and text onto a substrate through printing or inkjet printing. The manufacturing process of ink requires the uniform mixing of ink raw materials and auxiliary materials, a process that utilizes ink mixing equipment.

[0003] In existing ink mixing devices, ink raw materials and auxiliary materials far from the stirring plate cannot be reached by the stirring plate. When the ink raw materials and auxiliary materials near the stirring plate are mixed evenly, the ink raw materials and auxiliary materials far from the stirring plate will have problems such as undispersed color blocks and ink clumping. This prevents the ink raw materials and auxiliary materials from being mixed evenly and ultimately affects the use of the ink. Utility Model Content

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0027] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0028] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0029] refer to Figures 1 to 7 The ink mixing device according to a preferred embodiment of the present invention will be described in detail below, wherein the ink mixing device includes a device body 10, a lifting component 20, a driving component 30 and a stirring component 40.

[0030] The lifting assembly 20 includes a lifting drive component 21 and a lifting mounting frame 22. The lifting mounting frame 22 includes a mounting frame body 221 and at least one support arm 222. The lifting drive component 21 is disposed on the device body 10. The mounting frame body 221 is disposed at the output end of the lifting drive component 21. The support arm 222 is disposed on the mounting frame body 221.

[0031] The drive assembly 30 includes a drive mounting member 31, a stirring drive member 32, and a drive shaft 33. The drive mounting member 31 is connected to the support arm 222. The stirring drive member 32 is disposed on the drive mounting member 31. The drive shaft 33 is coaxially connected to the output end of the stirring drive member 32. The extension direction of the drive shaft 33 faces into a liquid storage container 91.

[0032] The stirring assembly 40 includes a stirring mounting member 41 and at least two stirring members 42. The stirring mounting member 41 is coaxially mounted to the end of the drive shaft 33 away from the stirring drive member 32. At least two of the stirring members 42 are evenly arranged on the stirring mounting member 41.

[0033] Preferably, the lifting drive component 21 is implemented as a telescopic cylinder.

[0034] It is worth mentioning that during the process of raising and lowering the lifting mounting frame 22 via the lifting drive component 21, the stirring mounting component 41 disposed on the frame arm 222 will drive the stirring component 42 to move out of and into the liquid storage container 91. That is to say, the output direction of the lifting drive component 21 is the direction that allows the stirring component 42 to move out of and into the liquid storage container 91.

[0035] Those skilled in the art will understand that during the rotation of the drive shaft 33 and the rotation of the stirring mounting component 41, the stirring mounting component 41 will drive the stirring component 42 to move, so as to mix the ink raw materials and auxiliary materials located in the liquid storage component 91 through the stirring component 42.

[0036] The stirring assembly 40 further includes a flow-limiting guide 43. The flow-limiting guide 43 is coaxially disposed on the stirring mounting component 41. The stirring component 42 is located inside the flow-limiting guide 43. The flow-limiting guide 43 is provided with a plurality of evenly spaced flow-guiding holes 4301.

[0037] It is worth mentioning that the stirring action of the stirring element 42 on the ink raw materials and auxiliary materials in the liquid storage element 91 will press the mixed ink raw materials and auxiliary materials towards and through the guide hole 4301, and then flow away from the stirring element 42 after passing through the guide hole 4301, so as to disperse the ink raw materials and auxiliary materials away from the stirring element 42, and finally achieve uniform mixing of the ink raw materials and auxiliary materials away from the stirring element 42.

[0038] In other words, the uniform mixing speed of ink raw materials and auxiliary materials away from the stirring element 42 is proportional to the speed of ink raw materials and auxiliary materials flowing out from the guide hole 4301.

[0039] Preferably, at least two of the stirring elements 42 are eccentrically disposed on the stirring mounting member 41, so that the stirring elements 42 impact the ink raw materials and auxiliary materials in an irregular manner, thereby making the ink raw materials and auxiliary materials more uniformly mixed.

[0040] Because the ink raw materials and auxiliary materials are impacted by the stirring member 42 in different ways, the ink raw materials and auxiliary materials move intensely in the space between the stirring member 42 and the flow-limiting guide member 43, which increases the speed of the ink raw materials and auxiliary materials flowing out of the guide hole 4301, thereby increasing the speed at which the ink raw materials and auxiliary materials away from the stirring member 42 achieve uniform mixing.

[0041] The stirring element 42 has a flow-guiding surface 4201, which is located near the axis of the stirring mounting element 41. The flow-guiding surface 4201 guides ink raw materials and auxiliary materials into the space between the stirring element 42 and the flow-limiting guide element 43 for mixing. Due to the guiding effect of the flow-guiding surface 4201, the flow rate of ink raw materials and auxiliary materials entering the space between the stirring element 42 and the flow-limiting guide element 43 is increased. Since the size of the guide hole 4301 remains unchanged, the velocity of ink raw materials and auxiliary materials flowing out of the guide hole 4301 is increased, thereby increasing the uniform mixing speed of ink raw materials and auxiliary materials away from the stirring element 42.

[0042] It should be noted that the longer the drive shaft 33 is, the lower the stability of the drive shaft 33 when the stirring drive 32 drives it to rotate. In other words, the longer the drive shaft 33 is, the more easily it will produce radial displacement when rotating.

[0043] Preferably, the stirring assembly 40 further includes a reinforcing member 44. The reinforcing member 44 includes at least two reinforcing members 441 and a connecting member 442. The connecting member 442 has a rotating through-hole through which the drive shaft 33 passes, and the connecting member 442 is located at the end of the drive shaft 33 away from the stirring drive member 32. One end of each of the at least two reinforcing members 441 is evenly distributed around the periphery of the stirring mounting member 41. The other ends of each of the at least two reinforcing members 441 are evenly connected to the periphery of the connecting member 442. This prevents radial displacement of the drive shaft 33 during rotation via the connecting member 442.

[0044] In this embodiment, the reinforcing member 44 further includes at least one anti-wear component 443. The anti-wear component 443 is disposed in the rotating through hole, and is located between the drive shaft 33 and the inner wall of the rotating through hole. The anti-wear component 443 is used to prevent the drive shaft 33 from rubbing against the inner wall of the rotating through hole during rotation, thereby preventing the ink raw materials and auxiliary materials in the liquid storage component 91 from being contaminated by debris.

[0045] Preferably, the ink mixing device further includes a control element 50. The control element 50 is disposed on the device body 10, and the lifting drive component 21 and the stirring drive component 32 are electrically connected to the control element 50 so as to control the start and stop of the lifting drive component 21 and the stirring drive component 32 through the control element 50.

[0046] In this embodiment, both the arm 222 and the drive mounting member 31 have a shaft hole, and the shaft holes of the arm 222 and the drive mounting member 31 are passed through a rotating shaft, so that the drive mounting member 31 is movably connected to the arm 222 through the rotating shaft.

[0047] It is worth mentioning that when the drive mounting component 31 rotates relative to the frame arm 222 via the rotating shaft, the extension direction of the drive shaft 33 will change, thereby changing the position of the stirring mounting component 41 connected to the drive shaft 33. This changes the position of the stirring component 42 connected to the stirring mounting component 41 in the liquid storage component 91, increasing the stirring range of the stirring component 42, which is beneficial for the uniform mixing of ink raw materials and auxiliary materials in the liquid storage component 91.

[0048] It should be noted that the stirring drive 32 will vibrate during operation. The vibration will be transmitted through the drive mounting 31, the arm 222 and the mounting frame body 221, causing the output end of the lifting drive component 21 to deviate, thereby damaging the lifting drive component 21.

[0049] Preferably, the lifting assembly 20 further includes a limiting member 23. The limiting member 23 includes a limiting rod 231 and a sliding member 232. The limiting rod 231 is disposed on the mounting frame body 221, and the extending direction of the limiting rod 231 is consistent with the output direction of the lifting drive assembly 21. The sliding member 232 is mounted on the lifting drive assembly 21. The sliding member 232 has a limiting through hole that matches the outer diameter of the limiting rod 231, and the limiting rod 231 movably passes through the limiting through hole of the sliding member 232.

[0050] In other words, as the mounting frame body 221 moves in a predetermined direction under the push of the output end of the lifting drive component 21, the limiting rod 231 provided on the mounting frame body 221 will slide in the limiting through hole. By limiting the limiting through hole of the sliding member 232, the output end of the lifting drive component 21 is prevented from shifting due to the vibration of the stirring drive component 32, thereby preventing damage to the lifting drive component 21.

[0051] It should be noted that, since the ink raw materials and auxiliary materials in the liquid storage component 91 are not transparent, the operator cannot determine the depth to which the drive shaft 33 drives the stirring mounting component 41 into the liquid storage component 91. During the stirring process of the ink raw materials and auxiliary materials in the liquid storage component 91, there is a possibility that the stirring component 42 and the flow limiting guide component 43 may abut against the bottom wall of the liquid storage component 91, causing damage to the liquid storage component 91.

[0052] Preferably, the distance between the lower end of the limiting rod 231 and the main body 10 of the device is the same as the distance between the lower end of the drive shaft 33 and the bottom wall of the liquid storage component 91, so as to determine the distance between the lower end of the drive shaft 33 and the bottom wall of the liquid storage component 91 by the height of the lower end of the limiting rod 231, thereby avoiding damage to the bottom wall of the liquid storage component 91 by the stirring component 42 and the flow limiting guide component 43.

[0053] In this embodiment, the limiting rod 231 has a measuring element 2311, which is used to visually display the distance the sliding member 232 moves, so as to control the depth of the stirring mounting member 41, the stirring member 42 and the flow limiting guide member 43 entering the liquid storage member 91, so that the stirring member 42 and the flow limiting guide member 43 stir and mix the ink raw materials and auxiliary materials at the bottom wall of the liquid storage member 91 in a manner close to the bottom wall of the liquid storage member 91.

[0054] In another modified embodiment, the limiting member 23 further includes a ranging member 233. The ranging member 233 is disposed on the lifting drive member 21 and electrically connected to the control member 50. The ranging member 233 determines the distance between the stirring member 42 and the flow-limiting guide member 43 and the bottom wall of the liquid storage member 91 by detecting the height of the lifting drive member 21 above the ground, and controls the stirring member 42 and the flow-limiting guide member 43 to stir and mix the ink raw materials and auxiliary materials at the bottom wall of the liquid storage member 91 in a manner close to the bottom wall of the liquid storage member 91.

[0055] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
