Description

Technical Field

[0001] The utility model relates to a meat grinder, in particular to a meat grinder with low calorific value, belonging to the field of meat processing equipment. Background Art

[0002] Meat grinder is a machine used by meat processing enterprises to process raw meat into granular meat fillings of varying specifications according to different process requirements during the production process. It is widely used in various sausages, ham, luncheon meat, meatballs, salty flavors, pet food and other meat products industries.

[0003] In the existing meat grinder, the operation mode between the propeller and the bushing is sliding friction. In this way, during the meat grinding process, the friction between the propeller and the bushing will quickly generate a large amount of heat, which will cause the temperature of the propeller and the head module to rise rapidly. When reaching a certain temperature, it is easy to cause the meat to deteriorate. At present, the ice box cooling method is usually used to reduce the temperature of the propeller and the head module, but it has many shortcomings. For example, the ice box is preheated during the cooling process to form water droplets, which drip onto the workbench and form water on the desktop, increasing the difficulty of cleaning; the ice box is external, the operation process is manually controlled, and the operation is inconvenient; it increases the cost of using the meat grinder, etc. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a meat grinder with low heat generation and no need for external cooling.

[0005] In order to solve the above technical problems, the meat grinder provided by the utility model includes a head guide tube, a step bushing and a bearing, the bearing is arranged in the head guide tube, the step bushing is provided with a limiting step, the step bushing passes through the bearing, and the limiting step falls on the bearing.

[0006] In the utility model, a limiting groove is arranged in the machine head guide tube, and the bearing is embedded in the limiting groove.

[0007] In the utility model, the propeller in the meat grinder is in close contact with the front end surface of the step bushing.

[0008] The beneficial effects of the present invention are as follows: (1) through the cooperation of the step bushing and the bearing, the sliding friction between the propeller and the bushing in the meat grinder is eliminated, no heat is generated between the propeller and the bushing, and only the rolling friction of the bearing itself occurs during the operation of the propeller, thereby reducing the heat generation, thereby achieving the goal of not heating up the propeller and other components, and ultimately achieving the purpose of cooling the meat grinder, avoiding the many shortcomings caused by the use of external cooling measures such as ice boxes; (2) a limiting groove is processed at the tail of the head guide tube, the bearing is embedded in the limiting groove, and the step bushing is passed through the inner hole of the bearing, thereby ensuring the stable operation of the propeller, the step bushing and the bearing, and improving the reliability of the meat grinder; (3) the present invention has a simple structure, low manufacturing cost, and is easy to disassemble and repair.

[0015] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0018] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.

[0021] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0022] like Figure 1As shown, the meat grinder of this embodiment includes a head guide tube 1, a bearing 2, a step bushing 3, a propeller 4, a meat grinder 5, a knife disc 6, a hand wheel 7 and a meat grinder body 8. One end of the head guide tube 1 is connected to the meat grinder body 8, and the top of the head guide tube 1 is connected to the feed tray 11 on the meat grinder body 8.

[0023] The front end of the propeller 4 is equipped with a meat grinder 5 and a knife disc 6 in sequence, and the rear end of the propeller 4 passes through the end step bushing 3 and the bearing 2 in sequence to be connected with the driving mechanism in the meat grinder body 8.

[0024] like Figures 1 to 3 As shown, the top of the die guide tube 1 is provided with a feed port, and the interior is a cavity adapted to the structure of the step bushing 3, the propeller 4, the cross knife, and the knife disc 6. The front of the die guide tube 1 is provided with a limit groove 9, which is used to embed and position the bearing 2.

[0025] like Figure 4 As shown, a limiting step 10 is provided on the step bushing 3 . When the step bushing 3 passes through the inner hole of the bearing 2 , the bushing limiting step 10 falls on the outside of the inner hole of the bearing 2 .

[0026] During assembly, first insert the step bushing 3 into the bearing 2, and then assemble the bearing 2 to the limit groove 9 in the head guide tube 1; the rear end of the propeller 4 is passed through the step bushing 3 and the bearing 2 in turn and connected to the driving mechanism in the meat grinder body 8; then the meat grinder 5, the knife disc 6 and the hand wheel 7 are assembled in turn at the front end of the propeller 4, and the hand wheel 7 is locked.

[0027] After the assembly is completed, the rear part of the propeller 4 is kept in close contact with the front end surface of the step bushing 3. In this way, when the meat grinder is working, there is no direct friction between the propeller 4 and the step bushing 3, and only the rolling friction of the bearing 2 itself occurs during the operation of the propeller 4, thereby avoiding the propeller 4 from generating a large amount of heat when working, and simply achieving the technical effect of not heating up the meat grinder when working.

[0028] In this embodiment, the meat grinder body 8, the meat grinder 5, the knife disc 6 and the hand wheel 7 are all existing structures, so they are not described in detail here.

[0029] Many specific details are elaborated in the above description to facilitate a full understanding of the present invention, but the above examples are merely preferred implementation methods of the present invention and cannot be used to limit the scope of rights of the present invention. Simple modifications and equivalent changes made to the above examples based on the essence of the present invention still fall within the scope of the present invention.
