Description

Technical Field

[0001] This utility model relates to the field of enamel glaze processing technology, and in particular to an enamel glaze grinding mill. Background Technology

[0002] Enamelware is widely used in many industries such as construction and home appliances, and its quality depends on the glaze. The particle size of the glaze is related to the performance of enamelware products; both excessively coarse and excessively fine glazes will have adverse effects. An enamel glaze grinding mill is a device specifically designed to crush and grind enamel glazes to achieve the required particle size and fineness.

[0003] However, traditional grinding mills have some problems when in use:

[0004] Relying on fixed annular screens, raw materials are often screened in one fixed place, resulting in incomplete screening, dead zones, and low efficiency.

[0005] Glaze raw materials that fail to pass through the sieve cannot be effectively carried up for further crushing and grinding, thus failing to form an efficient recycling process. This easily leads to material residue, making it difficult to improve grinding efficiency and resulting in uneven particle size in the final product. Utility Model Content

[0006] The purpose of this invention is to provide a grinding mill for enamel glaze, which solves the above-mentioned problems when used in operation.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grinding mill for enamel glaze, comprising a grinding mill housing, an end cover, and a hopper. The end cover is provided at the front end of the grinding mill housing, and the front end of the end cover is connected to a hopper for feeding. A discharge trough for discharging material is opened at the bottom of the inside of the grinding mill housing, and the discharge trough is connected to the grinding chamber inside the grinding mill housing. A rotating toothed disc is rotatably provided at the rear end of the inside of the grinding mill housing. Moving grinding steel teeth are fixed at the front end of the rotating toothed disc, and stationary grinding steel teeth are fixed at the rear end of the end cover. The stationary grinding steel teeth are placed inside the grinding mill housing and between the moving grinding steel teeth. An annular screen is rotatably provided on the inner side wall of the grinding mill housing for screening the ground glaze. A drive assembly is provided on one side of the bottom of the inside of the grinding mill housing for driving the annular screen to rotate. Vibration assemblies are provided on both sides of the bottom of the grinding mill housing.

[0008] Preferably, guide grooves are provided on the front and rear inner walls of the mill housing. An external toothed ring is rotatably installed inside the guide groove and is fixed to the front and rear outer walls of the annular screen. An internal cavity is provided on one side of the bottom of the mill housing. The internal cavity is connected to the inside of the guide groove. A dual-shaft motor is installed inside the internal cavity. Drive gears are fixed on the front and rear shafts of the dual-shaft motor. The two drive gears are located on one side of the two guide grooves and mesh with them.

[0009] Preferably, upper connecting blocks are fixed on both sides of the bottom of the grinding mill housing, springs are provided at the bottom of the upper connecting blocks, and lower connecting seats are connected to the bottom of the springs. Vibration motors are installed on both sides of the rear end of the grinding mill housing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model provides a grinding mill for enamel glaze. Through gears driving an external gear ring, a ring-shaped screen rotates within the mill housing, significantly improving screening efficiency. In traditional screening methods, raw materials are often fixed in one place or rely on a fixed ring-shaped screen, resulting in incomplete screening and low efficiency. However, the continuously rotating ring-shaped screen in this device allows each surface to contact the glaze raw material sequentially, ensuring that every screen participates in the process and eliminating screening dead zones. Simultaneously, glaze raw materials that fail to pass through the screen are carried upwards by the rotating screen and precisely fall back between the moving and stationary grinding teeth for further crushing and grinding. In this way, the glaze raw material forms an efficient circulating processing flow within the equipment, continuously undergoing fine processing, effectively avoiding material residue, significantly improving grinding efficiency, and ensuring uniform particle size of the final product.

[0012] 2. The enamel glaze grinding mill provided by this utility model, by starting a vibrating motor, uses the vibration force generated by the motor and the elastic force of the spring to make the grinding mill shell vibrate continuously, and the internal annular screen vibrates synchronously when rotating, to shake and screen the crushed and ground glaze raw materials, which significantly improves the screening effect and ensures the uniformity of the finished product particle size.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figures 1 to 6 As shown, this utility model discloses a grinding mill for enamel glaze, comprising a grinding mill housing 1, an end cover 2, and a hopper 3. The end cover 2 is provided at the front end of the grinding mill housing 1, and the hopper 3 for feeding is connected to the front end of the end cover 2. A discharge trough 4 for discharging material is provided at the bottom of the interior of the grinding mill housing 1, and the discharge trough 4 is connected to the grinding chamber inside the grinding mill housing 1. A rotating toothed disc 5 is rotatably provided at the rear end of the interior of the grinding mill housing 1, and a moving grinding steel tooth 7 is fixed at the front end of the rotating toothed disc 5. A stationary grinding steel tooth 6 is fixed at the rear end of the end cover 2. The stationary grinding steel tooth 6 is placed inside the grinding mill housing 1 and between the moving grinding steel teeth 7. An annular screen 51 is rotatably provided on the inner side wall of the grinding mill housing 1 for screening the ground glaze. A drive assembly is provided on one side of the bottom of the interior of the grinding mill housing 1 for driving the annular screen 51 to rotate. Vibration assemblies are provided on both sides of the bottom of the grinding mill housing 1.

[0023] Guide grooves 54 are provided on the front and rear inner walls of the mill housing 1. An external toothed ring 52 is rotatably installed inside the guide groove 54. The external toothed ring 52 is fixed on the front and rear outer walls of the annular screen 51. An internal cavity 55 is provided on one side of the bottom of the mill housing 1. The internal cavity 55 is connected to the inside of the guide groove 54. A dual-shaft motor 56 is installed inside the internal cavity 55. Drive gears 53 are fixed on the front and rear shafts of the dual-shaft motor 56. The two drive gears 53 are located on one side of the two guide grooves 54 and mesh with them.

[0024] Upper connecting blocks 11 are fixed on both sides of the bottom of the mill housing 1. A spring 12 is provided at the bottom of the upper connecting block 11. A lower connecting seat 13 is connected to the bottom of the spring 12. Vibration motors 14 are installed on both sides of the rear end of the mill housing 1.

[0025] Specifically, a drive motor is connected to the rear end of the rotating gear disk 5 to drive the rotating gear disk 5 to rotate the grinding steel teeth 7.

[0026] Figure 1 This is the state when end cap 2 is closed. Figure 2 and Figure 3 This is the state when the end cover 2 is open. When the end cover 2 is closed, the stationary grinding steel teeth 6 on the end cover 2 will be inserted between the moving grinding steel teeth 7.

[0027] The glaze raw material to be crushed and ground is fed into the grinding mill housing 1 through the hopper 3. The rotating moving grinding steel teeth 7 and the stationary stationary grinding steel teeth 6 can crush and grind the fed glaze raw material.

[0028] When the grinding mill is working, the dual-shaft motor 56 is started, which drives the drive gear 53 to rotate. The drive gear 53 drives the outer gear ring 52 to rotate, causing the annular screen 51 to roll inside the grinding mill housing 1. When the glaze raw material, after being crushed and ground by the moving grinding steel teeth 7 and the stationary grinding steel teeth 6, falls onto the annular screen 51, the rotating annular screen 51 will cause the crushed and ground glaze raw material to roll inside the annular screen 51, thus performing a rolling screening process on the crushed and ground glaze raw material. The finer glaze material is screened out and discharged through the discharge chute 4. The glaze raw material that is not screened by the annular screen 51 is carried upward and falls back between the moving grinding steel teeth 7 and the stationary grinding steel teeth 6, so as to crush and grind the glaze raw material again. This process is repeated, so that the glaze raw material can be fully crushed and ground, thereby improving the grinding efficiency.

[0029] It should be noted that, in order to ensure that the annular screen 51 can better lift the glaze material and bring it up between the moving grinding steel teeth 7 and the stationary grinding steel teeth 6, a vertical plate can be installed on the inner wall of the annular screen 51 to lift the glaze material.

[0030] At the same time, the vibration motor 14 is started, and the vibration force generated by the vibration motor 14, together with the elastic force of the spring 12, makes the mill housing 1 vibrate continuously. When the mill housing 1 vibrates, the annular screen 51 inside it vibrates while rotating, so that the annular screen 51 can shake and screen the crushed and ground glaze raw materials, thereby improving the screening effect.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
