Description

Technical Field

[0001] This utility model relates to the field of ink preparation structure, specifically a printing ink preparation device. Background Technology

[0002] During the processing of printing inks or coatings, different materials need to be added for formulation due to variations in color and performance. Currently, the commonly used formulation equipment is a disperser. A disperser includes at least a lifting frame, a motor, a stirring shaft, and dispersing plates. The lifting frame is equipped with a material cylinder clamp. In use, the material is fed into the material cylinder, which is then fixed to the bottom of the disperser by the material cylinder clamp. The stirring shaft is adjusted by changing the lifting frame, and the motor controller drives the stirring shaft. The dispersing plates then uniformly mix the material. However, it has been found that long-shaft stirring shafts tend to wobble during rotation (short-shaft shafts, referring to those no longer than 0.5m, generally do not experience this). For structures requiring a cap, the gap between the cap and the stirring shaft is small, and the shaking can cause the cap to be thrown off or rotate with the shaft, potentially causing injury to workers and posing a safety risk. Furthermore, some materials require specific temperatures for formulation, which current single-equipment systems cannot meet. There is currently no standardized equipment on the market, making it difficult to guarantee the consistency of the formulated materials. Utility Model Content

[0003] The purpose of this invention is to provide a printing ink preparation device to solve the problem of low safety caused by the shaking of the stirring shaft during rotation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a printing ink preparation device, comprising a disperser and a preparation cylinder, wherein the disperser comprises a support frame, a stirring mechanism, a clamping mechanism, and a lifting mechanism, the stirring mechanism is mounted on the support frame via the lifting mechanism, the clamping mechanism is disposed on the support frame, and the preparation cylinder is clamped by the clamping mechanism, the stirring mechanism comprises a driving component, a driving shaft, and a stirring blade, the stirring blade is mounted on the driving shaft, the driving shaft is connected to the driving component, a retainer is disposed on the support frame, the retainer comprises a mounting base, a first support rod, a second support rod, and a retaining disc, a bearing is disposed inside the retaining disc, the retaining disc is mounted on the stirring mechanism via the bearing, the first support rod and the second support rod are slidably hinged, and the second support rod and the retaining disc are rotatably connected.

[0005] As a further improvement to the above technical solution: The disperser is equipped with a heater at the bottom, and the feed cylinder is connected to the heater.

[0006] The drive unit includes a motor and a frequency converter, and the output end of the motor is connected to the drive shaft.

[0007] The clamping mechanism includes a guide rail frame, an adjusting shaft rotatably mounted on the guide rail frame, and a clamping arm hinged to the guide rail frame. A sleeve is hinged to the clamping arm, and an adjusting rod is threaded into the sleeve. The adjusting rod is connected to the adjusting shaft via a universal joint, and an operating handle is provided at one end of the adjusting rod.

[0008] The guide rail frame is equipped with a central support arm.

[0009] The lifting mechanism includes a guide column, a guide plate, and a drive belt. The motor is slidably mounted on the guide column via a sliding block, and one end of the sliding block is slidably engaged with the guide plate.

[0010] The sliding block is equipped with a suspension rope, and a counterweight is suspended at the other end of the suspension rope.

[0011] The disperser consists of multiple sets, each with different stirring blades.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The cage structure is connected to the drive shaft via bearings, limiting the radial wobble of the drive shaft and ensuring the stability of the stirring blades even at high speeds. This guarantees uniform mixing, avoids problems of incomplete mixing in certain areas, and also reduces vibration and noise during equipment operation.

[0013] The ink barrel is equipped with an induction cooker heater with temperature control at the bottom. For materials that require heating for reaction or dissolution, the barrel temperature can be precisely controlled to promote chemical reactions between materials, ensure the stability and consistency of the ink formulation, and thus improve the quality of the final product.

[0014] The lifting mechanism achieves smooth lifting of the mixing mechanism through guide columns, guide plates, and a drive belt. Combined with the suspension rope and counterweight on the sliding block, the weight of the mixing mechanism is balanced, making lifting operations more effortless and smoother. This facilitates the installation and disassembly of the material cylinder, as well as the adjustment of the mixing blade position according to the cylinder height and material quantity.

[0015] The clamping mechanism drives the clamping arms to open and close via an adjusting shaft and adjusting rod, enabling it to firmly clamp material cylinders of different specifications. The addition of a central support arm creates a three-point positioning system, further enhancing the stability of the material cylinder during the mixing process and preventing it from shifting or tipping over.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] 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.

[0022] like Figures 1 to 3 As shown, the printing ink preparation device of this embodiment includes a disperser and a preparation cylinder 5. The disperser includes a support frame 1, a stirring mechanism 2, a clamping mechanism 3, and a lifting mechanism 4. The stirring mechanism 2 is mounted on the support frame 1 via the lifting mechanism 4. The clamping mechanism 3 is disposed on the support frame 1, and the preparation cylinder 5 is clamped by the clamping mechanism 3. The stirring mechanism 2 includes a driving component 21, a driving shaft 22, and a stirring blade 23. The stirring blade 23 is mounted on the driving shaft 22, and the driving shaft 22 is connected to the driving component 21. A retainer 6 is provided on the support frame 1, and its connection method is bolt connection or welding.

[0023] A heater 7 is installed at the bottom of the disperser, and the feed cylinder 5 is connected to the heater 7. For materials that need to be heated, the feed cylinder 5 is heated by the heater 7, which is an induction cooker with temperature control.

[0024] The lifting mechanism 4 includes a guide column 41, a guide plate 42 and a drive belt 43. The motor is slidably mounted on the guide column 41 via a sliding block 44, and one end of the sliding block 44 is slidably engaged with the guide plate 42.

[0025] A suspension rope 45 is provided on the sliding block 44, and a counterweight 46 is suspended at the other end of the suspension rope 45. The weight of the counterweight 46 is slightly greater than the weight of the sliding block 44 and the motor. Without the action of external force, the sliding block 44 tends to move upward.

[0026] like Figure 4 As shown, the retainer 6 includes a mounting base 61, a first support rod 62, a second support rod 63, and a retaining disc 64. A bearing 65 is installed inside the retaining disc 64, which is mounted on the stirring mechanism 2 via the bearing 65. The first support rod 62 and the second support rod 63 are slidably hinged (i.e., the second support rod 64 has a sliding groove; the first support rod 62 is slidably rotated with the sliding groove via a pin, allowing the second support rod 63 to rotate around the pin and the sliding groove to slide). The second support rod 63 and the retaining disc 64 are rotatably connected. It should be noted that... Figure 1 and Figure 3The cage 6 in the diagram is shown as a schematic, illustrating two symmetrically arranged support rod structures for ease of understanding. The inner ring of the bearing 65 is fixedly mounted on the drive shaft 22 and can move up and down with the drive shaft 22. The outer ring of the bearing 65 is fixedly connected to the retaining disc 64. Because the retaining disc 64 is restricted by the support rods, the bearing 65 does not move radially, thus suppressing the wobbling of the drive shaft 22. In some embodiments, a sliding positioning cylinder can be provided on the retaining disc 64. This sliding positioning cylinder slides in conjunction with the retaining disc 64, and the lower part of the sliding positioning cylinder can be connected to the cover of the material cylinder 5. Due to the restriction of the sliding positioning cylinder, the drive shaft 22 will not cause the cover to rotate.

[0027] The drive unit 21 includes a motor and a frequency converter, with the motor's output connected to the drive shaft 22. The frequency converter is used to control the motor's start and stop as well as its speed adjustment (300-7000 rpm).

[0028] like Figure 5 As shown, the clamping mechanism 3 includes a guide rail frame 31, an adjusting shaft 32 rotatably mounted on the guide rail frame 31, and a clamping arm 33 hinged to the guide rail frame 31. A sleeve 34 is hinged to the clamping arm 33. An adjusting rod 35 is internally threaded to the sleeve 34. The adjusting rod 35 is connected to the adjusting shaft 32 via a universal joint. An operating handle 36 is provided at one end of the adjusting rod 35.

[0029] like Figure 6 As shown, a central support arm 37 is provided on the guide rail frame 31. The addition of the central support arm 37, using three-point positioning, makes the positioning more accurate.

[0030] In another embodiment, there are two dispersers, and the stirring blades 23 of the two dispersers are different. The main difference is that the stirring blades 23 are different in size, similar to the coarse mixing and fine mixing design, which can provide overall processing efficiency.

[0031] In use, place the mixing cylinder 5 on the heater 7 and introduce the material to be dispersed into the mixing cylinder 5 (the material should not exceed 2 / 3 of the mixing cylinder 5). Push the mixing cylinder 5 until it contacts the central support arm 37. Then, rotate the operating handle 36 to rotate the adjusting rod 35, causing the position of the sleeve 34 and the adjusting rod 35 to change, which in turn changes the position of the clamping arm 33, clamping the mixing cylinder 5. Next, the sliding block 44 descends through the drive belt 43 (synchronous belt structure or chain drive structure, driven by a lifting motor), stopping when it reaches the appropriate position. Pass the cover (usually a two-piece structure) through the drive shaft 22 and place it on the mixing cylinder 5. Start the motor of the stirring mechanism to drive the stirring blade 23 to rotate, dispersing the material. During this process, the retaining disc 64 rises and falls with the drive shaft 22. During the rising and falling process, the second support rod 63 moves accordingly. The three second support rods 63 are used to ensure the limit of the retaining disc 64, so as to achieve radial limit of the drive shaft 22 and avoid the long shaft stirring shaft from shaking, which could lead to a safety accident.

[0032] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics of the solutions is not described in detail here. For those skilled in the art, this utility model is obviously not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
