Description

Technical Field

[0001] The invention relates to the technical field of food engineering, in particular to a grinding roller assembly and a grinding machine. Background Art

[0002] In recent years, with the increasing diversification of consumer demand, food processing companies need to continuously launch new products to meet market changes. The role of mills in new product development is becoming increasingly important, especially in grinding different types of raw materials and creating novel food forms and tastes. Researchers can use mills to prepare powder samples of different particle sizes and qualities for the development of innovative products such as functional foods and special dietary foods. For example, through ultrafine grinding technology, functional foods rich in dietary fiber can be developed, or through low-temperature grinding technology, organic foods that retain more nutrients can be developed.

[0003] Some grinding mills in the prior art usually integrate the driving mechanism and the grinding roller assembly in the material container, making these key components difficult to access, causing great inconvenience in daily maintenance and cleaning. In addition, in the process of squeezing materials into powder, some grinding mills usually have the defect that the material powder is thrown to the inner wall of the top cover by the centrifugal force when the material powder is rotated and squeezed from the container. The powder attached to the inner wall of the top cover may fall off irregularly during subsequent operations and may be mixed into the subsequently ground material, resulting in uneven particle size distribution of the finished product, and even large particles or agglomerations. The powder may also fall off when the top cover is opened, resulting in material waste. Although some grinding mills in the prior art are equipped with devices that can clean the inside of the top cover, these cleaning devices usually require the addition of additional driving sources, which not only increases the complexity and cost of the equipment, but may also affect the overall performance and reliability of the equipment.

[0043] It should be noted that the conduction component 203 includes a fixed frame 203a fixedly connected to the top of the top cover 102, a threaded rod 203b fixedly installed on the inner wall of the fixed frame 203a through a bearing, an internal thread block 203c threadedly connected to the outer surface of the threaded rod 203b, a connecting plate 203d fixedly connected to the outer surface of the internal thread block 203c and used in conjunction with the servo motor 201a, and a handwheel 203e fixedly installed on the through end of the threaded rod 203b.

[0044] Among them, the internal thread block 203c is limited by the fixed frame 203a, so that the internal thread block 203c can drive the connecting plate 203d to move linearly through the rotation of the threaded rod 203b, and then the servo motor 201a, the connecting column 201b, the first pulley 201c, the belt 201d, the second pulley 201e, the support column 201f, the first gear disc 201g and the second gear disc 201h are driven to move synchronously through the connecting plate 203d.

[0049] Example 2

[0050] Reference Figure 2 , Figure 5 and Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: this embodiment provides a grinding mill, and the grinding mill includes: a supporting mechanism 100; a grinding roller assembly 200, and a cleaning mechanism 300.

[0051] The cleaning mechanism 300 includes a second fixed block 301 fixedly connected to the top of the top cover 102, a second connecting rod 302 fixedly installed on the inner surface of the second fixed block 301 through a bearing sleeve, a second spur gear 303 fixedly installed on the outer end of the second connecting rod 302, a third bevel gear 304 fixedly installed on the other end of the second connecting rod 302, a fourth bevel gear 305 meshing with the outer surface of the third bevel gear 304, and a fixed rod 306 fixedly connected to the inner surface of the fourth bevel gear 305.

[0052] Furthermore, the cleaning mechanism 300 also includes a reciprocating roller 307 fixedly connected to the through end of the fixed rod 306, a sleeve 308 slidably mounted on the outer surface of the reciprocating roller 307, a scraper 309 fixedly connected to the outer surface of the sleeve 308 and used in conjunction with the top cover 102, a limit block 310 fixedly connected to the inner surface of the other side of the scraper 309, and a limit rod 311 fixedly installed on the inner wall of the top cover 102 and used in conjunction with the limit block 310. A bearing sleeve for cooperation and rotation is installed at the connection between the fixed rod 306 and the top cover 102, the outer surface of the sleeve 308 is in sliding contact with the inner wall of the top cover 102, and the inner surface of the limit block 310 is in sliding contact with the outer surface of the limit rod 311.

[0053] It should be explained that the limiting block 310 is limited by the limiting rod 311 so that the limiting block 310 limits the scraper 309 and the sleeve 308 , so that the sleeve 308 can drive the sleeve 308 and the limiting block 310 to move back and forth in a straight line through the rotation of the reciprocating roller 307 .

[0054] During use, after the material is squeezed into powder, the servo motor 201a is turned off, and the hand wheel 203e is turned counterclockwise to drive the threaded rod 203b to rotate synchronously, so that the internal thread block 203c drives the connecting plate 203d to move linearly through the rotation of the threaded rod 203b, and the servo motor 201a, the connecting column 201b, the first pulley 201c, the belt 201d, the second pulley 201e, the supporting column 201f, the first toothed disc 201g and the second toothed disc 201h move synchronously, so that the second toothed disc 201h moves to a position meshing with the second spur gear 303, and the servo motor 201a is turned on again to drive the connecting column 201b and the first pulley 201c to rotate synchronously, and the first pulley 201c and the belt 201d are rotated. The second pulley 201e, the support column 201f and the second toothed disc 201h are driven to rotate, and then the second connecting rod 302 and the third bevel gear 304 are driven to rotate synchronously through the cooperation of the second toothed disc 201h and the spur gear second spur gear 303. The third bevel gear 304 and the fourth bevel gear 305 are driven to rotate the fixed rod 306 and the reciprocating roller. The limiting block 310 is limited by the limiting rod 311, so that the limiting block 310 limits the scraper 309 and the sleeve 308, so that the sleeve 308 drives the sleeve 308 and the limiting block 310 to move back and forth in a straight line through the rotation of the reciprocating roller 307, so that the scraper 309 scrapes the material powder attached to the inner wall of the top cover 102 into the material container 101.

[0055] In summary, through the coordination between the various components in the conduction component 203, the power of the driving mechanism 201 can be flexibly transmitted to the grinding roller mechanism 202 or the cleaning mechanism 300, so that the driving mechanism 201 can not only drive the grinding roller mechanism 202 to squeeze the material into powder, but also drive the cleaning mechanism 300 to scrape the material powder attached to the inner wall of the top cover 102 into the material container 101 to prevent the powder from mixing into the subsequent ground material, so as to prevent the material from having large particles or agglomeration while avoiding material waste.
