Description

Technical Field

[0001] The utility model belongs to the technical field of printing ink mixing, and particularly relates to a mixing device for printing ink raw materials. Background Art

[0002] In the production of printing ink, various raw materials need to be proportioned and mixed evenly before entering the next process for inkjet use. However, in the subsequent inkjet process, the nozzle is often blocked. The reason is that, in all probability, during the mixing of raw materials, the stirring is not uniform enough, resulting in the existence of raw materials with larger particles. In the subsequent inkjet process, the larger particles cannot be ejected from the nozzle, causing blockage. The blocked nozzle will greatly reduce the subsequent inkjet effect, and will also cause damage to the nozzle under long-term blockage, affecting the production progress. In addition, it will cause accessory loss and increase the production cost. Therefore, the first problem to be solved is whether the raw materials can be mixed well during the mixing process, and the second problem is how to break up the large particles. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a mixing device for printing ink raw materials. While driving the transmission shaft in the feed cylinder by a motor, the upper mixing blade and the lower mixing blade connected to the lower end are driven, so that the raw materials at the bottom of the mixing tank surge upward. At the same time, the spiral blade on the transmission shaft extrudes the raw materials in the feed channel and drops them into the raw materials for mixing, improving the mixing efficiency and being able to break up large particles.

[0004] To achieve the above object, the technical solution adopted by the utility model is:

[0005] A mixing device for printing ink raw materials, comprising a mixing tank, a tank cover and a stirring assembly. The tank cover covers the upper opening of the mixing tank. The tank cover is provided with a first feed inlet and a second feed inlet. The stirring assembly includes a motor, a feeding member and a mixing member. The motor is arranged on the tank cover, and the output end of the motor penetrates through the tank cover and extends into the inner cavity of the mixing tank. The feeding member includes a feeding cylinder, a transmission shaft and a mixing plate. The feeding cylinder is connected to the inner side wall of the mixing tank in a matching manner. The outer side wall of the feeding cylinder is provided with a feeding channel and a discharging channel. The opening of the feeding channel is matched with the first feed inlet, and the opening of the discharging channel faces downward. The discharging channel includes several groups, and several groups of the discharging channels are circumferentially distributed on the outer side wall of the feeding cylinder with the feeding cylinder as the rotation center, and several groups of the discharging channels are axially distributed on the outer side wall of the feeding cylinder in rows of three groups; the transmission shaft is arranged in the feeding cylinder and penetrates downward through the feeding cylinder. The upper end of the transmission shaft is connected to the output end of the motor, and the lower end of the transmission shaft is connected to the mixing member. The outer side wall of the transmission shaft is provided with a spiral blade, and the outer end edge of the spiral blade is matched with the inner side wall of the feeding cylinder; the mixing plate is fixedly connected to the outer side wall of the feeding cylinder, and the inner side wall of the mixing tank is provided with a plug-in groove, and the mixing plate is matched with the plug-in groove.

[0006] The mixing member includes a rotating shaft, an upper stirring blade and a lower stirring blade. The upper stirring blade and the lower stirring blade are connected to the rotating shaft from top to bottom. The lower end of the transmission shaft is connected to the upper end of the rotating shaft. The rotation radius of the upper stirring blade is greater than that of the lower stirring blade, and the rotation directions of the upper stirring blade and the lower stirring blade are opposite to the rotation direction of the spiral blade.

[0007] For the mixing device of printing ink raw materials adopting this structure, the function of the mixing tank is to receive different raw materials for mixing. The tank cover that covers and is locked in the form of bolts at its upper opening. The first feed inlet and the second feed inlet on the tank cover are used to separately throw different raw materials into the mixing tank for mixing. And the bottom of the mixing tank is provided with a flange connection port for externally transporting the mixed raw materials. The bottom of the mixing tank is in a closed state before the mixing is completed.

[0008] In order to achieve complete mixing of the raw materials placed in the mixing tank, a driving force is required to stir in the mixing tank for raw material mixing. Therefore, a motor is installed on the tank cover. The output end of the motor extends into the mixing tank and is connected to the transmission shaft. The rotating shaft connected to the lower end of the transmission shaft is provided with upper mixing blades and lower mixing blades respectively. The upper mixing blades and the lower mixing blades are arranged in a structure with a larger upper part and a smaller lower part, and their rotation directions are the same. When the motor is started, the upper mixing blades and the lower mixing blades stir the raw materials at the bottom of the mixing tank and convey them upward, achieving a preliminary tumbling effect from bottom to top. The outside of the transmission shaft is covered with a feed cylinder. The outer edge of the spiral blade on the outer side wall of the transmission shaft cooperates with the inner side wall of the feed cylinder, and the rotation direction of the spiral blade is opposite to that of the upper mixing blades and the lower mixing blades. Therefore, when driving the rotation of the upper mixing blades and the lower mixing blades to make the raw materials surge from bottom to top, the spiral blade is in a state of pressing and conveying downward. The feed channel on the feed cylinder cooperates with the first feed port, and several groups of discharge channels are distributed in a circular pattern and an axial arrangement. The openings of the discharge channels all point downward. Therefore, when adding viscous raw materials for mixing, feeding needs to be carried out from the first feed port. The continuously rotating motor not only drives the upper mixing blades and the lower mixing blades to surge the raw materials, but also drives the spiral blade to press the raw materials in the feed channel downward onto several groups of discharge channels. The discharge ports of several groups of discharge channels are not in the same position and can be dispersed and added to the surging raw materials for mixing, avoiding large lumps of raw materials being directly put into the mixing tank for mixing, which may result in poor dispersion of large raw material blocks. Other liquid raw materials can be directly put in from the second feed port, and the surging raw materials can complete the operation of being stirred evenly.

[0009] In order to further disperse and mix the surging raw materials evenly, mixing plates are provided on the outer side wall of the feed cylinder. The mixing plates are inserted into the insertion slots on the inner side wall of the mixing tank. Preferably, the mixing plates are composed of at least three groups. The three groups of mixing plates are distributed in a circular pattern on the outer side wall of the feed cylinder and are clamped in the insertion slots in the mixing tank in a tripod state, which can achieve a more stable connection effect and keep the feed cylinder in a stable state in the mixing tank. The mixing plates can be set in a plate shape, a spiral shape, or an inwardly convex column shape, so that the raw materials during the surging process can continuously flow through the area where the mixing plates are located for continuous mixing. After mixing, the raw materials are exported from the bottom of the mixing tank and enter the next process.

[0010] Furthermore, a support rod is provided at the lower opening of the mixing tank, and the rotating column on the support rod abuts against the lower end surface of the rotating shaft.

[0011] Compared with the prior art, the advantages of the present utility model are as follows: The motor drives the transmission shaft to drive the upper stirring blade and the lower stirring blade to stir in the mixing tank, causing the raw materials to surge from bottom to top, achieving a preliminary raw material flow mixing effect. Moreover, through the spiral blades on the rotating transmission shaft, the viscous raw materials in the first feed inlet are pressed towards the discharge channel. The discharge ports of several groups of discharge channels are not in the same position and can be dispersed and added to the surging raw materials for mixing, avoiding the situation where large lumps of raw materials are directly put into the mixing tank for mixing, resulting in poor dispersion of large raw material lumps. And the surging raw materials will strike on the mixing plate, achieving the second-step mixing and dispersing effect, enabling the raw materials to be well dispersed.

Several groups of the discharge channels 324 are circumferentially distributed on the outer side wall of the feeding cylinder 321 with the feeding cylinder 321 as the rotation center. Several groups of the discharge channels 324 are axially distributed on the outer side wall of the feeding cylinder 321 in rows of three groups; the transmission shaft 322 is arranged in the feeding cylinder 321 and penetrates downward through the feeding cylinder 321.

[0023] Furthermore, a support rod 12 is provided at the lower opening of the mixing tank 1, and the rotating column 121 on the support rod 12 abuts against the lower end surface of the rotating shaft 331.

[0024] Description of the working mode of the present utility model:

[0025] For the mixing device of printing ink raw materials adopting this structure, the function of the mixing tank 1 is to receive different raw materials for mixing. A tank cover 2 is covered and locked in the form of bolts at its upper opening. The first feed port 21 and the second feed port 22 on the tank cover 2 are used to separately throw different raw materials into the mixing tank 1 for mixing. A flange connection port is provided at the bottom of the mixing tank 1 for externally transporting the mixed raw materials. Before the mixing is completed, the bottom of the mixing tank 1 is in a closed state.

[0026] In order to achieve complete mixing of the raw materials placed in the mixing tank 1, a driving force is required to stir the raw materials in the mixing tank 1 for raw material mixing. Therefore, a motor 31 is provided on the tank cover 2. The output end of the motor 31 extends into the mixing tank 1 and is connected to the transmission shaft 322. The rotating shaft 331 connected to the lower end of the transmission shaft 322 is respectively provided with an upper stirring blade 332 and a lower stirring blade 333. The upper stirring blade 332 and the lower stirring blade 333 are arranged in a structure with a larger upper part and a smaller lower part, and their rotation directions are the same. When the motor 31 is started, the upper stirring blade 332 and the lower stirring blade 333 stir the raw materials at the bottom of the mixing tank 1 and convey them upward, realizing a preliminary tumbling effect from bottom to top. The outer part of the transmission shaft 322 is covered with a feed cylinder 321. The outer edge of the spiral blade 3221 on the outer side wall of the transmission shaft 322 cooperates with the inner side wall of the feed cylinder 321, and the rotation direction of the spiral blade 3221 is opposite to the rotation directions of the upper stirring blade 332 and the lower stirring blade 333. Therefore, when driving the rotation of the upper stirring blade 332 and the lower stirring blade 333 to cause the raw materials to surge from bottom to top, the spiral blade 3221 is in a state of pressing and feeding downward. The feed channel 323 on the feed cylinder 321 cooperates with the first feed port 21, and several groups of discharge channels 324 are distributed in a circumferential and axial arrangement. The openings of the discharge channels 324 all point downward. Therefore, when it is necessary to add viscous raw materials for mixing, feeding needs to be carried out from the first feed port 21. The continuously rotating motor 31 not only drives the upper stirring blade 332 and the lower stirring blade 333 to surge the raw materials, but also drives the spiral blade 3221 to press the raw materials in the feed channel 323 downward onto several groups of discharge channels 324. The discharge ports of several groups of discharge channels 324 are not in the same position and can be dispersed and distributed in the surging raw materials for addition and mixing, avoiding large pieces of raw materials being directly put into the mixing tank 1 for mixing, resulting in poor dispersion of large pieces of raw materials. Other liquid raw materials can be directly put in from the second feed port 22, and the raw materials in the surging state can complete the operation of being stirred evenly.

[0027] In order to further disperse and mix the raw materials in the surging process, a mixing plate 325 is provided on the outer side wall of the feeding cylinder 321. The mixing plate 325 is inserted into the insertion groove 11 on the inner side wall of the mixing tank 1. Optimally, the mixing plate 325 is composed of at least three groups. The three groups of mixing plates 325 are circumferentially distributed on the outer side wall of the feeding cylinder 321 and are clamped in the insertion groove 11 in the mixing tank 1 in a tripod state, which can achieve a more stable connection effect, making the feeding cylinder 321 in a stable state in the mixing tank 1. The mixing plate 325 can be set in a plate shape, a spiral shape, or a convex column shape inward, so that the raw materials in the surging process can continuously flow through the area where the mixing plate 325 is located for continuous mixing. After mixing, the raw materials are exported from the bottom of the mixing tank 1 and enter the next process.

[0028] In order to support and limit the rotation shaft 331, a support rod 12 is provided at the lower opening of the mixing tank 1. The rotating column 121 on the support rod 12 abuts against the lower end face of the rotation shaft 331, so that the rotation shaft 331 can always stay on the rotating column 121 during rotation, avoiding the rotation failure of the upper stirring blade 332 and the lower stirring blade 333 caused by the rotation shaft 331 falling off during rotation.

[0029] The beneficial effects of the present utility model are as follows: The motor 31 drives the transmission shaft 322 to drive the upper stirring blade 332 and the lower stirring blade 333 to stir in the mixing tank 1, so that the raw materials surge from bottom to top, achieving a preliminary raw material flow mixing effect. Furthermore, through the spiral blade 3221 on the rotating transmission shaft 322, the viscous raw materials in the first feeding port 21 are pressed towards the discharge channel 324. The discharge ports of several groups of discharge channels 324 are not in the same position and can be dispersedly distributed in the surging raw materials for addition and mixing, avoiding the situation that large pieces of raw materials are directly put into the mixing tank 1 for mixing, resulting in poor dispersion of large pieces of raw materials, and the surging raw materials will hit the mixing plate 325, achieving the second mixing and dispersing effect, so that the raw materials can be well dispersed.

[0030] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
