Description

Technical Field

[0001] The utility model belongs to the technical field of ink production equipment, and particularly relates to a sand mill for ink production. Background Art

[0002] An ink production sand mill is a type of grinding equipment used in the ink, coating, and pigment industries. It places a large amount of grinding media, such as carbide rods or zirconium oxide beads, within a barrel. These grinding media, stirred by a high-speed disperser assembly, create a strong collision and shearing effect on the material, effectively refining the material particles in a short period of time.

[0003] During the grinding and stirring process, the grinding media and ink material generate high-speed friction against the cylinder, generating a large amount of heat. To avoid damage to the ink material and reduce the high temperature and pressure inside the cylinder, existing sand mills are equipped with a cooling system on the cylinder to cool it. For example, patent publication number CN214439625U discloses a sand mill suitable for producing high-viscosity inks. This uses an inner and outer cylinder and a circulating coolant to cool the cylinder.

[0004] However, the above-mentioned cooling method has the following defects when used: since the coolant needs to circulate in the inner and outer cylinders, the sealing and structural strength of the cylinders are required to be high, and leakage is likely to occur after long-term use. Once the liquid penetrates into the cylinder, it will not only damage the ink material, but also create certain production risks, which is not conducive to safe production. Utility Model Content

[0005] The purpose of the utility model is to provide an ink production sand mill, which can cool the cylinder by air cooling, while ensuring cooling, improving the production safety of the equipment, and can collect the dust generated by processing during air cooling to avoid it being dispersed into the work area and causing environmental pollution.

[0006] The technical solutions adopted by this utility model are as follows:

[0007] A sand mill for producing ink comprises a machine body and a cylinder mounted on the machine body, the outer surface of the cylinder being integrally formed with fins, a cooling channel being formed between adjacent fins, an air supply hood being mounted in a ring sleeve on one end of the cylinder, an air outlet being integrally formed on the air supply hood to match the cooling channel, and the air outlet being extended into the cooling channel, an air inlet being integrally formed on the air supply hood for connecting to a cooling fan to blow the cold air flow into the cooling channel through the air outlet.

[0008] As a preferred solution, an air guide plate is integrally formed at the bottom of the air outlet, and the air guide plate is attached to the outer surface of the cylinder to guide the cold air flow into the cooling channel.

[0009] As a preferred solution, one end of the cylinder is provided with a connection port connected to the machine body, and the other end is provided with a discharge port for discharging materials, and a sealing cover is detachably installed in the discharge port.

[0010] As a preferred solution, a fixing ring is detachably mounted on the outer periphery of the discharge port, and a collecting mesh cover connected to the cooling channel is fixedly mounted around the fixing ring for filtering and collecting dust generated during processing.

[0011] As a preferred solution, a diverter cover is provided between the air inlet pipe opening and the air supply cover. The diverter cover is trapezoidal in shape and is used to divert the cold air flow into the air supply cover.

[0012] As a preferred solution, a diversion plate for diversion is fixedly welded inside the diversion hood, the diversion plate is parallel to the side wall of the diversion hood, the side wall of the diversion hood is tangent to the side wall of the air supply hood, and at least one group of diversion plates is symmetrically arranged.

[0013] As a preferred solution, the fins are corrugated, and the height of the fins raised compared to the surface of the cylinder gradually increases from one end to the other.

[0014] The technical effects achieved by this utility model are:

[0015] The utility model arranges an air supply hood in conjunction with the fins, and the air supply hood can be used to connect a cooling fan, and the cold air flow is discharged through the air outlet and then guided into the cooling channel by the deflection of the air guide plate, taking away the heat from the cylinder and the surface of the fins, thereby cooling the cylinder and alleviating the high temperature and high pressure in the cylinder during grinding. Compared with the water-cooling structure in the prior art, the overall safety is higher, and there will be no leakage that affects safe production. In addition, the structural strength requirements of the cylinder are not high, and it is convenient for production.

[0016] The utility model cooperates with the air supply cover, fins and collecting mesh cover, and can send the dust generated in the production process into the collecting mesh cover along the cooling channel for collection during the cooling of the cylinder, so that the dust can be collected and then processed centrally to prevent it from spreading into the air and causing pollution.

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0027] Example 1:

[0028] like Figure 1-Figure 3 As shown, a sand mill for ink production includes a machine body (not shown in the figure) and a barrel 1 installed on the machine body. A connecting port 12 connected to the machine body is provided at one end of the barrel 1, and the sanding spindle on the machine body also extends from this end into the barrel 1. At the same time, a discharge port 13 for discharging materials is provided at the other end, and a sealing cover 14 is detachably installed in the discharge port 13, through which various pipelines required for production are connected.

[0029] Among them, fins 11 are integrally formed on the outer surface of the cylinder 1, and the fins 11 are arrayed circumferentially on the outer surface of the cylinder 1, and cooling channels are formed between adjacent fins 11. An air supply hood 2 is installed in a ring sleeve on one end of the cylinder 1. In this embodiment, it is installed at the end close to the connecting port 12, and an air outlet 21 is integrally formed on the air supply hood 2 to match the cooling channel, and the air outlet 21 is extended into the cooling channel, and an air inlet pipe port 23 is integrally formed on the air supply hood 2, which can be connected to the cooling fan installed on the body, and the cold air flow is transported into the air supply hood 2 and transmitted in a ring along its internal channel, and then blown into the cooling channel through the air outlet 21 and flows along the cooling channel to take away the heat from the surface of the cylinder 1 and the fins 11, thereby cooling the inside of the cylinder 1.

[0030] Refer to the attached Figure 3 In order to stably introduce the cold air flow into the cooling channel, an air guide plate 22 is integrally formed at the bottom of the air outlet 21, and the air guide plate 22 is attached to the outer surface of the cylinder 1. In this way, after the cold air flows out of the air outlet 21, it will be guided by the air guide plate 22 to flow into the cooling channel, thereby stably guiding the cold air flow into the cooling channel to ensure the cooling of the cylinder 1.

[0031] Refer to the attached Figure 1-Figure 2 In order to collect the dust generated during production, a fixing ring 15 is detachably mounted on the outer periphery of the discharge port 13. The detachable method may be threaded or clamped, which is not limited here. In this embodiment, a threaded connection method is adopted, and a collecting mesh cover 16 connected to the cooling channel is fixedly mounted around the fixing ring 15. When the cold air flow flows in the cooling channel, the cold air flow can be sent into the collecting mesh cover 16 at the other end along the cooling channel, thereby filtering the grinding dust in the cold air flow through the collecting mesh cover 16, so that the dust can be collected and then processed centrally to prevent it from spreading into the air and causing pollution.

[0032] Example 2:

[0033] like Figure 4-Figure 6 As shown, a sand mill for ink production is provided. This embodiment is basically the same as the first embodiment, with the only difference being that a diverter hood 24 is provided between the air inlet pipe opening 23 and the air supply hood 2. The diverter hood 24 is trapezoidal in shape and is used to divert the cold air flow into the air supply hood 2. By increasing the distance between the air inlet pipe opening 23 and the air supply hood 2, the cold air flow can be better transported to the entire air supply hood 2 space, and will not be concentrated only on a few air outlets 21 opposite thereto, so that all the air outlets 21 on the air supply hood 2 can discharge air evenly, thereby improving the cooling effect.

[0034] Refer to the attached Figure 6In order to further improve the diversion effect, a diversion plate 25 for diversion is fixedly welded inside the diversion cover 24. The diversion plate 25 is parallel to the side wall of the diversion cover 24, and the side wall of the diversion cover 24 is tangent to the side wall of the air supply cover 2, which can further evenly distribute the airflow, so that the air outlet 21 on the side away from the air inlet pipe 23 can also evenly discharge air, further improving the cooling effect.

[0035] Among them, in this embodiment, the diverter plates 25 are symmetrically arranged in two groups, which can divide the cold air flow into three channels, and transmit them to the two sides, the middle and directly below, so as to evenly divide the air flow; of course, in other embodiments, the diverter plates 25 are symmetrically arranged in at least one group, which can be set as needed.

[0036] Example 3:

[0037] like Figure 7 As shown, a sand mill for ink production is shown. This embodiment is basically the same as the first embodiment, with the only difference being that the fins 11 are corrugated and arranged in a circular array on the outer surface of the cylinder 1, which can reduce the flow rate of the cold air flow in the cooling channel formed by the fins 11, while increasing the area and time of contact with the fins, thereby increasing the heat absorption and ensuring the heat dissipation effect. Moreover, the protrusion height of the fins 11 compared to the surface of the cylinder 1 gradually increases from one end to the other end, and in this embodiment gradually increases from one end of the connection port 12 to the other end, which can reduce the dispersion of the air flow during the flow process, so that it can be more concentrated in the cooling channel, ensuring continuous cooling of the cylinder 1.

[0038] The working principle of the present invention is as follows: when in use, the cooling fan on the machine body is connected through the air inlet pipe 23, the cold air flow is filled into the air supply hood 2 through the cold air fan, and after being discharged through the air outlet 21, it is guided into the cooling channel by the deflection of the air guide plate 22, taking away the heat from the surface of the cylinder 1 and the fins 11, and sending the cold air flow into the collecting mesh cover 16 at the other end along the cooling channel, so that the grinding dust in the cold air flow is filtered through the collecting mesh cover 16, so that the dust can be collected and then processed centrally to prevent it from spreading into the air and causing pollution.

[0039] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
