Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a grinding machine. Background Technology

[0002] Grinding mills are suitable for manufacturing pastes such as paints, inks, pigments, and plastics. For example, titanium dioxide, as a matting agent for polyester fibers, directly affects the quality of polyester and its subsequent spinning and processing. Therefore, titanium dioxide usually needs to be finely ground before being added to the reaction system. The matting agent is mainly prepared by mixing bagged titanium dioxide powder with ethylene glycol solution in a certain proportion in a preparation tank for a period of time. The suspension is then fed into the grinding mill at a certain speed for the first grinding. The ground material enters the matting agent circulation tank. The grinding mill is started for the second time, and the ground suspension enters the dilution tank.

[0003] Existing grinding machines generally consist of a power module, a grinding barrel, and a grinding section. The power module drives the grinding section to rotate inside the grinding barrel, thereby performing grinding. For example, Chinese Patent Publication No. CN220027202U discloses "a horizontal grinding machine," which, by setting up a grinding component, can more effectively grind the coating. The grinding component, through a vibration motor, a drive motor, a stirring plate, and a spring, can improve the grinding effect and also increase the filtration speed. By setting up a connecting plate, which is fixedly installed with a support frame, and the support frame is fixedly installed with the grinding box, the vibration motor is started, causing the connecting plate to vibrate, thereby causing the grinding box to vibrate. By setting up a rotating column, which is fixedly installed with one end of the drive motor's rotating shaft, the coating is transported into the interior of the grinding box. After the drive motor is started, the stirring plate grinds the coating. By starting the vibration motor, the grinding box vibrates, thereby improving the grinding effect and enhancing the filtration of the coating.

[0004] However, in actual use, after grinding, the mixture inside the grinding barrel is not easy to collect when it is discharged. Most of them rely on natural gravity to flow out, which requires a lot of time to wait for the mixture to be discharged before it can be mixed and processed again, thus affecting the processing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need to spend a lot of time waiting for the mixture to be discharged before it can be mixed again, which affects processing efficiency, and to propose a grinding machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a grinding machine, including a base and a drive structure. A grinding barrel is fixedly mounted on the base. Both ends of the grinding barrel have openings and sealing caps. A grinding tube, which is poweredly connected to the drive structure, is rotatably mounted inside the grinding barrel. Multiple grinding units are mounted on the grinding tube. The grinding barrel has an inlet pipe and an outlet pipe, both of which are equipped with control valves. A one-way valve is installed inside the inlet pipe. A receiving hopper is located on one side of the base.

[0007] Furthermore, a pressure pipe for an external pressure device is fixedly installed on the grinding barrel, and an end cap that cooperates with the pressure pipe is fixedly installed on the sealing cover.

[0008] Furthermore, the end cap has a through hole corresponding to the pressure tube, the through hole is connected to the grinding tube, and the grinding tube is provided with multiple through grooves.

[0009] Furthermore, the grinding unit includes a grinding block disposed on the grinding tube, the grinding block having a threaded hole for mounting a scraper, the scraper being in contact with the inner wall of the grinding barrel.

[0010] Furthermore, the base is provided with two support tubes, the receiving hopper is disposed between the two support tubes, and the two support tubes are provided with positioning structures that cooperate with the receiving hopper.

[0011] Furthermore, the positioning structure includes a baffle, and each of the support tubes is provided with a sliding groove. Both sides of the baffle are provided with sliding plates that cooperate with the sliding groove.

[0012] Furthermore, a motor is fixedly installed inside the support tube, and the output shaft of the motor is fixedly connected to a screw. The screw is rotatably connected to the support tube and threadedly connected to the slide plate.

[0013] The grinding machine proposed in this utility model has the following advantages: In this invention, by setting an external pressurizing device to pressurize the grinding barrel during grinding, it helps to promote the uniform dispersion of pigment particles, avoid agglomeration, and make the pigment mixture more delicate and stable. Secondly, in this invention, after grinding is completed, pressure is applied to the grinding barrel through a pressure pipe, thereby quickly discharging the mixture in the grinding barrel, reducing waiting time and improving processing efficiency. A positioning structure is set to position the hopper to prevent misalignment with the discharge pipe. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A grinding machine includes a base 1 and a drive structure 2. The drive structure 2 includes a motor, a controller, and a belt. The output shaft of the motor is poweredly connected to a grinding tube 5 via the belt. A grinding barrel 3 is fixedly mounted on the base 1. Both ends of the grinding barrel 3 have openings, and both ends of the grinding barrel 3 are fixedly mounted with sealing caps 4. A grinding tube 5, poweredly connected to the drive structure 2, is rotatably mounted inside the grinding barrel 3. Multiple grinding units 6 are mounted on the grinding tube 5. The grinding barrel 3 is equipped with a feed pipe 31 and a discharge pipe 32. Both the feed pipe 31 and the discharge pipe 32 are equipped with control valves. A one-way valve is installed inside the feed pipe 31. A receiving hopper 7 is provided on one side of the base 1, and rollers are provided at the bottom of the receiving hopper 7. A pressure pipe 8 of an external pressure device is fixedly mounted on the grinding barrel 3, and an end cap 41 that cooperates with the pressure pipe 8 is fixedly mounted on the sealing cap 4.

[0018] In this invention, by setting an external pressurizing device on the pressurizing pipe 8, pressure can be applied to the grinding barrel 3 during grinding, thereby increasing the internal pressure of the grinding barrel 3. This helps to promote the uniform dispersion of pigment particles, avoid agglomeration, and make the pigment mixture more delicate and stable. After grinding is completed, pressure is applied to the grinding barrel 3 through the pressurizing pipe 8, thereby quickly discharging the mixture in the grinding barrel 3 into the receiving hopper 7 along the discharge pipe 32 for collection, reducing waiting time and improving processing efficiency.

[0019] Furthermore, in this embodiment, the end cap 41 is provided with a through hole corresponding to the pressurizing tube 8. The through hole is connected to the grinding tube 5. The grinding tube 5 is provided with multiple through grooves. When the grinding barrel 3 is pressurized, the high-pressure gas enters the grinding barrel 3 along the through grooves.

[0020] Furthermore, in this embodiment, the grinding unit 6 includes a grinding block 61 disposed on the grinding tube 5. The grinding block 61 has a threaded hole for mounting a scraper. The scraper contacts the inner wall of the grinding barrel 3 and scrapes off the substances attached to the inner wall of the grinding barrel to prevent affecting the proportion of each substance in the processed mixture and avoid producing defective products.

[0021] It should be noted that in this embodiment, the base 1 is provided with two support pipes 11, the receiving hopper 7 is provided between the two support pipes 11, and the two support pipes 11 are provided with positioning structures 9 that cooperate with the receiving hopper 7. The positioning structure 9 restricts the position of the receiving hopper 7 and prevents the receiving hopper 7 from being misaligned with the discharge pipe 32, which would cause the mixture to leak.

[0022] Furthermore, in this embodiment, the positioning structure 9 includes a baffle 91, and the support tube 11 is provided with a sliding groove. Both sides of the baffle 91 are provided with a sliding plate 92 that cooperates with the sliding groove. The sliding groove restricts the position of the sliding plate 92 and the baffle 91, thereby restricting the position of the receiving hopper 7.

[0023] More specifically, in this embodiment, a motor 93 is fixedly installed inside the support tube 11, and a screw 94 is fixedly connected to the output shaft of the motor 93. The screw 94 is rotatably connected to the support tube 11 and threadedly connected to the slide plate 92. The motor 93 drives the screw 94 to rotate, pushing out the receiving hopper after receiving the material, making it convenient for the operator to replace the new receiving hopper.

[0024] Working method: During operation, an external pressurizing device is connected to the pressurizing pipe 8 to pressurize the grinding barrel 3 during grinding, which increases the internal pressure of the grinding barrel 3. This helps to promote the uniform dispersion of pigment particles, avoid agglomeration, and make the pigment mixture more delicate and stable. The material adhering to the inner wall of the grinding barrel is scraped off by a scraper to prevent it from affecting the proportion of each substance in the processed mixture and to avoid producing unqualified products. After grinding is completed, the pressurizing pipe 8 pressurizes the grinding barrel 3, thereby quickly discharging the mixture in the grinding barrel 3 into the receiving hopper 7 through the discharge pipe 32 for collection. The screw 94 driven by the motor 93 rotates to push out the receiving hopper after the material has been collected, making it convenient for the operator to replace it with a new one.

[0025] 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.
