[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0015] like Figures 1 to 4 As shown, an adjustable damping device for testing load of a meat grinder 100 includes: a base 2, a magnetic powder brake 3, a connecting component 4, and a fixing component 5. The magnetic powder brake 3 is fixed on the base 2, and the output shaft of the magnetic powder brake 3 is horizontally set. The magnetic powder brake 3 can adjust the damping. One end of the connecting component 4 is connected to the output shaft of the magnetic powder brake 3, and the other end of the connecting component 4 is used to connect to the square nut head 101 at the front end of the screw on the meat grinder 100. The fixing component 5 is installed on the base 2 and is used to fix the meat grinder 100.

[0016] In this application, during use, the meat grinder 100 to be tested is placed on the base 2 and fixed by the fixing component 5. The screw of the meat grinder 100 is aligned with the magnetic powder brake 3. The connecting component 4 is used to connect the screw of the meat grinder 100 to the magnetic powder brake 3. The magnetic powder brake 3 is adjusted to a low resistance. The meat grinder 100 is started to run at a low speed. After the connection and operation are stable, the meat grinder 100 is switched to the highest speed. Then, the load on the magnetic powder brake 3 is gradually increased according to the standard requirements for testing.

[0017] The magnetic powder brake 3 is existing technology and is available on the market. The magnetic powder brake 3 can be manually controlled in terms of its damping, thereby simulating the operation of the meat grinder 100 after meat products are fed in.

[0018] The magnetic powder brake 3 of this application adjusts the damping magnitude without consuming meat raw materials, significantly reducing testing costs.

[0019] Specifically, the connecting assembly 4 includes a first connecting rod 41 and a second connecting rod 42. The first connecting rod 41 is fixed on the output shaft of the magnetic powder brake 3. The second connecting rod 42 is keyed to the first connecting rod 41. The other end of the second connecting rod 42 is provided with a square tube 4221 corresponding to the square nut head 101. The square tube 4221 is used to connect the square nut head 101.

[0020] The output shaft of the magnetic powder brake 3 drives the first connecting rod 41 fixed thereon to rotate. The first connecting rod 41 transmits torque to the second connecting rod 42 through a key connection. Finally, the square tube 4221 at the end of the second connecting rod 42 transmits the torque to the square nut head 101 of the screw of the meat grinder 100, forming a complete power transmission link.

[0021] The first connecting rod 41 and the second connecting rod 42 are detachable keyed connections, and the square tube 4221 and the square nut head 101 are fitted together. If it is necessary to replace parts or adapt to different specifications of square nuts in the future, they can be quickly disassembled and replaced, reducing costs.

[0022] Specifically, the second connecting rod 42 and the first connecting rod 41 are connected by a spline.

[0023] Specifically, the second connecting rod 42 and the first connecting rod 41 are connected by a round-headed flat key.

[0024] Specifically, the second connecting rod 42 includes a first connecting head 421 and a second connecting head 422. The first connecting head 421 is connected to the first connecting rod 41. The second connecting head 422 is axially limited to the first connecting head 421. The first connecting head 421 and the second connecting head 422 rotate synchronously. The first connecting head 421 and the second connecting head 422 are detachable.

[0025] For meat grinders of different specifications, the square nut on the screw of the 100 can be replaced individually with a second connector 422 with a corresponding square tube 4221, without the need to replace the entire second connecting rod 42, and without the need to customize a complete connecting assembly 4 for each screw, thus reducing spare parts costs and inventory pressure.

[0026] Specifically, the fixing component 5 includes a pressure strip 51, a first connecting rod 52, a second connecting rod 53, a first adjusting nut 54, and a second adjusting nut 55; the upper surface of the base 2 is provided with a plurality of limiting grooves 21; the lower ends of the first connecting rod 52 and the second connecting rod 53 are each provided with a limiting part 56, which is disposed in the limiting groove 21 to restrict the first connecting rod 52 and the second connecting rod 53 from disengaging in a direction away from the base 2; the pressure strip 51 is provided with a first through hole and a second through hole, the first adjusting nut 54 passes through the first through hole and is threadedly connected to the first connecting rod 52; the second adjusting nut 55 passes through the second through hole and is threadedly connected to the second connecting rod 53.

[0027] Place the meat grinder 100 on the base 2, with the meat grinder 100 located below the pressure bar 51. Then tighten the first adjusting nut 54 and the second adjusting nut 55. The height of the pressure bar 51 is controlled by adjusting the nuts, thereby pressing and fixing the meat grinder 100.

[0028] Specifically, a limiter 22 is installed on the base 2. The limiter 22 is used to abut against the meat grinder 100 to limit the movement of the meat grinder 100 away from the magnetic powder brake 3.

[0029] The limiter 22 can pre-position the placement of the meat grinder 100 so that the square nut head 101 at the front end of its screw is aligned with the square cylinder 4221 of the connecting component 4. This eliminates the need to repeatedly adjust the position of the meat grinder 100 to complete the docking, improving clamping efficiency. It also prevents the meat grinder 100 from moving away from the magnetic powder brake 3 during operation.

[0030] Specifically, the limiter 22 has a blocking plane 221, which is used to attach to the meat grinder 100.

[0031] The planar contact maximizes the contact area between the limiter 22 and the meat grinder 100, disperses the force when they collide, and prevents the meat grinder 100 from shifting or tilting due to vibration or reverse torque, thus ensuring that it always maintains a precise connection with the connecting component 4.

[0032] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0033] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
