Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, and in particular to a horizontal sand mill for ink grinding. Background Technology

[0002] In the actual production process, ink needs to undergo preliminary dispersion and mixing, and then be repeatedly ground in a sand mill to ensure that the ink does not contain particulate matter so that the ink can meet the factory standards. The existing ink raw material processing uses a horizontal sand mill, which usually feeds the ink raw material into the sand mill barrel and grinds it by controlling the collision of the sand beads with the ink raw material. Before processing, the number of sand beads inside needs to be adjusted to achieve the expected effect.

[0003] Currently, horizontal sand mills used for ink grinding on the market require the grinding cylinder to be disassembled for cleaning, and cleaning tools must be manually used to clean the inside of the grinding cylinder. This method is time-consuming, labor-intensive, and inconvenient for cleaning. Alternatively, a water spray nozzle can be installed on the grinding cylinder for rinsing. However, during the grinding process of the horizontal sand mill, the grinding beads will continuously hit the rinsing nozzle, which can easily damage the rinsing nozzle and thus shorten the service life of the rinsing structure in the horizontal sand mill. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in existing horizontal sand mills, water spray heads are installed on the grinding cylinder for rinsing, but during the grinding process, the grinding beads constantly hit the rinsing nozzle, which easily leads to damage to the rinsing nozzle and thus shortens the service life of the rinsing structure in the horizontal sand mill. Therefore, a horizontal sand mill for ink grinding is proposed.

[0005] To achieve the above objectives, the present invention employs the following technology: a horizontal sand mill for ink grinding, comprising a base, a controller provided on the upper left side of the base, a grinding tank provided on one side of the controller, a motor fixedly connected to the top of the controller, and a conveying mechanism provided on one side of the base.

[0006] The protective assembly includes a rotating block rotatably connected to one side of the grinding jar, an agitator connected inside the rotating block, a cylinder fixedly connected to one side of the rotating block, one side of the cylinder extending into the grinding jar and connected to an upper push plate, a guide rod fixedly connected to the top of one side of the agitator and a top plate connected to the top of the guide rod, a spring sleeved on the surface of the guide rod between the top plate and the agitator, a cover frame passing through the surface of the guide rod, and water spray heads on both sides of the agitator.

[0007] As a further description of the above technical solution: the conveying mechanism includes a water pump installed on one side of the base, the output end of the water pump is connected to a water outlet pipe, and the other end of the water outlet pipe is connected to a stirring pipe through a connector.

[0008] As a further description of the above technical solution: the output end of the motor is connected to the other end of the stirring tube.

[0009] As a further description of the above technical solution: a reinforcing frame is provided at the bottom of the grinding jar.

[0010] As a further description of the above technical solution: a feed pipe is provided on one side of the top of the grinding tank, and a discharge pipe is provided on the other side of the top of the grinding tank.

[0011] As a further description of the above technical solution: the two sides of the stirring tube are flat and grooves for embedding water spray heads are opened on both sides of the stirring tube.

[0012] As a further description of the above technical solution: both sides of the cover frame are in close contact with both sides of the stirring tube.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] By incorporating protective and conveying components, the water pump delivers water to the mixing tube through the outlet pipe during use, and then sprays it out through the spray nozzle to rinse the inner wall of the grinding tank. When the spray nozzle stops working, the cylinder drives the upper push plate to retract, and then the cover frame, under the action of the spring, descends to cover both sides of the mixing tube, thus preventing the grinding beads from hitting the spray nozzle during grinding, thereby protecting the spray nozzle and extending its service life.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 The horizontal sand mill for ink grinding provided in this embodiment includes a base 1, a controller 2 is provided on the upper left side of the base 1, a grinding tank 3 is provided on one side of the controller 2, a motor 5 is fixedly connected to the top of the controller 2, and a conveying mechanism 7 is provided on one side of the base 1.

[0023] The protective component 6 includes a rotating block 601 rotatably connected to one side of the grinding jar 3. A stirring tube 602 is connected inside the rotating block 601. A cylinder 603 is fixedly connected to one side of the rotating block 601. One side of the cylinder 603 extends to the grinding jar 3 and is connected to an upper push plate 604. A guide rod 605 is fixedly connected to the top of one side of the stirring tube 602, and a top plate is connected to the top of the guide rod 605. A spring 607 is provided between the top plate and the stirring tube 602 and sleeved on the surface of the guide rod 605. A cover frame 606 passes through the surface of the guide rod 605. Water spray heads 608 are provided on both sides of the stirring tube 602.

[0024] The cylinder 603 pushes or retracts the upper push plate 604. Since the upper surface of the upper push plate 604 is trapezoidal on both sides and the inner top wall of the cover frame 606 is in contact with it, when the upper push plate 604 is pushed or retracted, the cover frame 606 is driven to rise or fall under the action of the spring 607 to open or block the two sides of the stirring tube 602. This prevents the grinding beads from hitting the water spray head 608 during grinding, thereby protecting the water spray head 608 and extending its service life.

[0025] Specifically, such as Figure 1 and Figure 4 As shown, the conveying mechanism 7 includes a water pump 701 installed on one side of the base 1. The output end of the water pump 701 is connected to a water outlet pipe 702, and the other end of the water outlet pipe 702 is connected to the stirring pipe 602 through a connector.

[0026] The water pump 701 delivers water to the stirring tube 602 through the outlet pipe 702, and then sprays it out through the spray head 608 to rinse the inner wall of the grinding tank 3.

[0027] Specifically, such as Figure 1 and Figure 2As shown, the output end of the motor 5 is connected to the other end of the stirring tube 602.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, a reinforcing frame 4 is provided at the bottom of the grinding jar 3.

[0029] The reinforcing frame 4 supports the grinding jar 3, making the device operate more stably.

[0030] Specifically, such as Figure 1 As shown, a feed pipe 8 is provided on one side of the top of the grinding tank 3, and a discharge pipe 9 is provided on the other side of the top of the grinding tank 3.

[0031] Specifically, such as Figure 3 As shown, the two sides of the stirring tube 602 are flat, and grooves for embedding the water spray head 608 are provided on both sides of the stirring tube 602.

[0032] The spray head 608 is embedded inside the groove and does not extend beyond the opening of the groove, thus better concealing and protecting the spray head 608.

[0033] Specifically, such as Figure 4 As shown, both sides of the cover 606 are tightly fitted to both sides of the stirring tube 602.

[0034] The cover 606 fits tightly against the stirring tube 602 to enhance protection of the water spray head 608 inside the groove.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
