Description

Technical Field

[0001] This utility model relates to the field of stearic acid, specifically to a grinding device for preparing aqueous stearic acid. Background Technology

[0002] Zinc stearate is a white powder, insoluble in water, and is mainly used as a lubricant and release agent for styrene resin, phenolic resin, and amine resin. It also functions as a vulcanizing activator and softener in rubber. Aqueous emulsions of zinc stearate are called waterborne zinc stearate, which have a wide range of applications, including as a release agent, color retention agent, lubricant, and release agent.

[0003] A search revealed a utility model grinding device for processing zinc stearate, publication number CN218689753U. The device includes a storage tank, a grinding tank, and a ventilation box. The grinding tank is bolted to the top of the storage tank. A structural plate is welded to the top of the grinding tank. A protective sleeve is bolted to the top of the structural plate. A geared motor is mounted on the top of the protective sleeve via a mounting bracket. The output shaft of the geared motor is connected to a connecting rod via a connecting sleeve. A conical grinding block for grinding zinc stearate is bolted to the bottom of the connecting rod. The gap between the conical grinding block and the reinforcing metal plate in this utility model is a "V" shape, which allows for thorough grinding of the zinc stearate. Furthermore, by cooling the reinforcing metal plate, a low temperature is maintained, preventing the zinc stearate from overheating and melting during grinding.

[0004] The aforementioned patent merely modifies the grinding block into a "V" shaped structure to grind stearic acid. However, when encountering clumped stearic acid, it is prone to accumulation and blockage, thus hindering proper grinding. Furthermore, the patent does not allow the grinding block to move up and down, preventing the adjustment of the contact force between the grinding ball and the stearic acid, thereby reducing the efficiency of the grinding process.

[0005] Therefore, it is necessary to invent a grinding device for the preparation of aqueous stearic acid to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a grinding device for preparing aqueous stearic acid, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for preparing water-based stearic acid, comprising a support frame, a connecting block fixedly installed on one side of the support frame, a screw threaded through one side of the connecting block, a clamping block movably connected to one end of the screw, a grinding barrel movably connected to one side of the clamping block, a first drive motor disposed above the support frame, a lead screw fixedly installed at the lower end of the first drive motor, a movable frame movably connected to the outside of the lead screw, a sliding rod movably connected inside one side of the movable frame, a second drive motor disposed on one side of the movable frame, and a transmission rod fixedly installed at the lower end of the second drive motor.

[0008] Preferably, the clamping block forms a telescopic structure with the connecting block via a screw, and the clamping block is configured in a "U" shape.

[0009] Preferably, a screen is fixedly installed inside the grinding barrel, and a discharge port is provided on one side of the grinding barrel.

[0010] Preferably, the movable frame is connected to the support frame via a lead screw to form a lifting structure, and the movable frame is movably connected to the lead screw.

[0011] Preferably, the movable frame is connected to the support frame via a slide rod to form a sliding structure, and the slide rod is symmetrically arranged about its central axis.

[0012] Preferably, the lower end of the transmission rod is movably connected to the grinding disc, a threaded groove is provided on one side of the transmission rod, a bolt is movably connected inside the threaded groove, and grinding protrusions are provided on the lower part of the grinding disc.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. Through the setup of a support frame, a first drive motor, a lead screw, a movable frame, a slide bar, a second drive motor, a transmission rod, and a grinding disc, when encountering clumps of water-based stearic acid during the grinding process, the first drive motor drives the lead screw to rotate. The rotation causes the movable frame and the second drive motor on one side to adjust the grinding disc up and down. By lifting up and down, the water-based stearic acid is squeezed to avoid clogging. The lifting up and down also changes the contact force between the grinding disc and the surface of the water-based stearic acid. When the contact force is greater, the water-based stearic acid can be ground into a finer powder. The slide bars on both sides of the movable frame enhance the stability of the movable frame and the second drive motor when lifting up and down.

[0015] 2. By using a support frame, connecting block, screw, clamping block, transmission rod, grinding disc, threaded groove, bolts, and grinding protrusions, the grinding disc is rotated by turning the screw, which drives the clamping block to hold and fix the grinding barrel, enhancing stability during the grinding process. It also makes it easy for workers to remove and clean it. When the grinding disc is used for grinding for a long time, some wear will appear on the surface. The grinding disc and grinding protrusions can be easily disassembled and replaced by workers through bolt disassembly. This design improves the practicality of the grinding work.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5The grinding equipment for preparing water-based stearic acid shown includes a support frame 1. Connecting blocks 2 are fixedly installed on one side of the support frame 1. A screw 3 passes through one side of each connecting block 2. A clamping block 4 is movably connected to one end of the screw 3. The clamping block 4 forms a telescopic structure with the connecting blocks 2 via the screw 3. The clamping block 4 has a "U"-shaped structure. Rotating the screw 3 causes the clamping block 4 to clamp and fix the grinding barrel 5, enhancing stability during the grinding process and facilitating removal for cleaning. The grinding barrel 5 is movably connected to one side of the clamping block 4. A first drive motor 8 is installed above the support frame 1. A lead screw 9 is fixedly installed at the lower end of the first drive motor 8. The external movable connection is a movable frame 10. A sliding rod 11 is movably connected inside one side of the movable frame 10. A second drive motor 12 is provided on one side of the movable frame 10. A transmission rod 13 is fixedly installed at the lower end of the second drive motor 12. By driving the first drive motor 8, the lead screw 9 is rotated. The rotation causes the movable frame 10, the second drive motor 12 on one side, and the grinding disc 14 to be adjusted up and down. The water-based stearic acid is squeezed by the up and down movement, thereby avoiding clogging. Moreover, the up and down movement can also change the contact force between the grinding disc 14 and the surface of the water-based stearic acid. When the contact force is greater, the water-based stearic acid can be ground more finely.

[0026] like Figure 1 and Figure 3 As shown, a screen 6 is fixedly installed inside the grinding barrel 5, and a discharge port 7 is provided on one side of the grinding barrel 5. The water-based stearic acid is screened by the screen 6, and the ground water-based stearic acid is discharged through the discharge port 7.

[0027] like Figure 1 and Figure 4 As shown, the movable frame 10 forms a lifting structure with the support frame 1 via the lead screw 9. The movable frame 10 is movably connected to the lead screw 9. The first drive motor 8 is driven to rotate, thereby driving the movable frame 10 to lift and adjust. This can meet the user's height adjustment of the grinding disc 14, and also increase the contact area between the grinding disc 14 and the water-based stearic acid, making the water-based stearic acid grind finer.

[0028] like Figure 1 and Figure 4 As shown, the movable frame 10 forms a sliding structure with the support frame 1 through the slide rod 11. The slide rod 11 is symmetrically arranged around the central axis of the slide rod 11. The slide rod 11 arranged on both sides of the movable frame 10 can enhance the stability of the movable frame 10 and the second drive motor 12 when they are raised and lowered.

[0029] like Figure 5As shown, the lower end of the transmission rod 13 is movably connected to the grinding disc 14. A threaded groove 15 is provided on one side of the transmission rod 13. A bolt 16 is movably connected inside the threaded groove 15. Grinding protrusions 17 are provided on the lower part of the grinding disc 14. The grinding disc 14 and the grinding protrusions 17 can be disassembled and replaced by the workers by means of the bolt 16.

[0030] The working principle of this utility model is as follows: First, connect the external power supply. Then, lift the grinding barrel 5 onto the support frame 1. Next, the operator rotates the screw 3 to drive the clamping block 4 to fix and limit the grinding barrel 5, thereby improving the stability of the grinding barrel 5 during subsequent grinding. Then, pour water-based stearic acid into the grinding barrel 5. After pouring, turn on the switch of the grinding barrel 5. When the current passes through the motor coil, a magnetic field is generated, causing the motor rotor to generate magnetic force, which in turn generates rotational force to drive the transmission rod 13 and the grinding disc 14 to rotate. Then, turn on the switch of the first drive motor 8 above the support frame 1. When the current passes through the motor coil, a magnetic field is generated, causing the motor rotor to generate magnetic force, which in turn generates rotational force to drive the lead screw 9 to rotate. During rotation, the external actuator... The moving frame 10 is raised and lowered, driving the second drive motor 12 and the grinding disc 14 to rise and fall, so that the lowering grinding disc 14 contacts the surface of the water-based stearic acid for extrusion and grinding. When the contact force is greater, the water-based stearic acid can be ground into a finer powder. When the grinding disc 14 descends to the bottom and is about to contact the top of the screen 6, the switch of the first drive motor 8 is turned off. Next, the ground water-based stearic acid passes through the screen 6 and enters the bottom of the screen 6. Finally, the valve outside the discharge port 7 is opened to discharge the ground water-based stearic acid. After the grinding and discharge are completed, the switch of the second drive motor 12 is turned off to stop the rotation of the grinding disc 14. Then the external power supply is cut off. This completes the use of the grinding equipment for preparing water-based stearic acid.

[0031] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
