Description
Technical Field
[0001] The utility model relates to the field of food processing devices, in particular to a meat product cutting and fixing structure. Background Art
[0002] Meat cutting helps to ensure the quality of meat products. During the cutting process, unsafe parts such as diseased tissues, lymph nodes, and congestion can be removed to ensure the hygiene and safety of food. At the same time, professional cutting technology can also reduce meat damage, maintain the quality characteristics of meat such as texture, color and taste, and enhance consumers' product experience.
[0003] Meat products need to be fixed during the cutting process. At present, most of the fixed structures often only fix the meat products, but do not have the functions of angle adjustment and water washing of meat products. Without the angle adjustment function, the cutting equipment can only cut at a fixed angle, which will greatly limit its scope of application and flexibility. Meat products will produce some contaminants such as minced meat, blood and bacteria during the cutting process. Without the water washing function, these contaminants are easy to remain on the surface of the meat or on the equipment, increasing the risk of food safety.
[0004] Therefore, in view of the fact that the above-mentioned meat product cutting and fixing structure does not have the function of angle adjustment and water washing of meat products, a meat product cutting and fixing structure can be designed. Through rotation adjustment and flushing structure, the meat product can be fixed while facilitating the adjustment of the fixed angle during cutting and removing dirt on the surface of the meat product, thereby improving the cutting quality and hygiene standards.

[0027] See also Figure 5-6In this embodiment, the fixing assembly includes an L-shaped steel plate 901 and a threaded rod 902; a threaded hole is provided in the L-shaped steel plate 901 and is installed on the upper end of the turntable 808, and the threaded rod 902 is threadedly connected to the threaded hole.

The anti-skid pad is usually made of a material with a high friction coefficient, which can effectively increase the friction between the pressing plate 904 and the meat product to prevent the meat product from sliding during the cutting process. The flushing assembly includes an installation bin 1001, a nozzle 1002, a water hole 1003, and a water pipe 1004; the installation bin 1001 is installed on the outer walls of the left and right sides of the bracket 4, and the nozzle 1002 is installed on the installation bin 1001. In the loading bin 1001, a water hole 1003 is opened at the upper end of the workbench 2, and a water pipe 1004 is installed at the rear end of the bracket 4 and extends forward into the bracket 4. The loading bin 1001 is used to accommodate and protect the nozzle 1002. The nozzle 1002 is responsible for spraying clean water onto the meat product, which helps to remove dirt on the surface of the meat product and improve the cutting quality and hygiene standards. The water hole 1003 allows the waste water after cleaning to pass through the workbench 2 and then be discharged out of the equipment through the drain pipe 6. The water pipe 1004 is a pipeline connecting the external water source and the nozzle 1002, and is responsible for transporting the cleaning water to the nozzle 1002.
[0028] When working, the operator first places the meat product on the turntable 808, and then, by rotating the knob 903, the depth of the threaded rod 902 in the threaded hole of the L-shaped steel plate 901 can be easily adjusted, so that meat products of different thicknesses can be flexibly fixed. After the fixing is completed, the operator starts the cutter 703, and the cylinder 701 starts to work, driving the cutter 703 to move up and down accurately. In this process, the blade 704 accurately contacts the meat product and cuts it. Through the control console 3, the operator can easily adjust the thrust of the cylinder 701 and the rotation speed of the cutter 703 to adapt to meat products of different materials and thicknesses, thereby achieving accurate cutting;
[0029] During the cutting process, the nozzle 1002 will start to spray clean water onto the surface of the meat product, effectively removing dirt and impurities on the surface, which not only improves the quality of cutting, but also meets strict hygiene standards. The waste water after flushing flows smoothly into the workbench 2 through the water hole 1003, ensuring that the workbench 2 remains clean. When the entire cutting operation is completed, the operator only needs to open the drain pipe 6, and the waste water can be quickly discharged from the equipment;
[0030] If the operator needs to adjust the cutting angle, he only needs to operate the control console 3 simply to control the rotating motor 801 to start working. After receiving the command, the rotating motor 801 will quickly drive the No. 1 hollow shaft 802 to rotate. The movement of the No. 1 hollow shaft 802 further drives the No. 1 gear 803 fixed on its outer wall to rotate together. Through the meshing action between the gears, the power is effectively transmitted to the No. 2 gear 807 and the No. 2 hollow shaft 806, so that the turntable 808 can rotate smoothly. In this way, the fixed components and meat products can adjust the angles as the turntable 808 rotates to meet different cutting needs.
[0031] Through the above steps, through the coordinated operation of the cutting component, the rotating component, the fixing component and the flushing component, not only can the precise operation ensure the smooth cut of the meat product, significantly improve the overall quality of the product, and enhance its appearance, but also the meat product can be cut at multiple angles, which greatly meets different cutting needs and improves the flexibility of operation and work efficiency. In addition, it can also effectively remove dirt and residues on the surface of the meat product, improve the hygiene standards after cutting, and solve the problem that the meat product cutting fixing structure does not have the function of angle adjustment and water washing of meat products.
[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
