[0002] The catering industry often needs to use slicing tools to cut steaks, ribs, and fresh meat into the slices required by users. Traditional methods require thawing first and then manually cutting with a bone knife, which is time-consuming and labor-intensive. For the catering industry with a large supply volume, there are now slicing machines on the market. They refer to equipment that uses the transmission system and the movement of the knife group to cut steaks, ribs, fresh meat, and other medium and large-sized ingredients into slices, segments, and dices. Slicing machines are widely used in meat processing plants, the production of family steaks, meat processing in fresh supermarkets, and production and processing in central kitchens of all sizes.

[0003] For example, the utility model patents with announcement numbers CN215968970U and CN210960176U both disclose relevant content about the chopping machine. In the cutting mechanism of the existing chopping machine, the counterweight block is often directly connected to the blade shaft of the chopping knife by welding. The welding is firm and the operation is relatively stable after the dynamic balance is calibrated. However, the chopping knife is installed at the end of the blade shaft with bolts. When the chopping knife is replaced after wear, it is necessary to remove the bolts and reinstall the chopping knife. Due to individual differences in the chopping knife and deviations in the threaded hole positions, it is often necessary to readjust the dynamic balance after installing the new knife. The welded counterweight is often not convenient for on-site debugging, so the counterweight assembly needs to be redesigned to facilitate on-site debugging.

[0004] Therefore, it is necessary to develop a steak chopping machine for the above-mentioned defects. Utility Model Content

[0025] The core of the utility model is to provide a meat steak chopping machine, which is convenient for on-site debugging after reinstalling the chopping knife, and improves the quality and efficiency of knife changing operation.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0029] Example 1

[0030] like Figures 1 to 3As shown, a meat chopping machine includes a frame body 1, a cutting mechanism, a feeding mechanism and an electric control system. Like the existing chopping machine, the left and right ends of the top of the frame body 1 are respectively connected horizontally with a feed trough 101 and a discharge trough 102. The feeding clamp of the feeding mechanism is arranged in the feed trough 101. The cutting mechanism includes a knife shaft 2, a chopping knife 3 and a counterweight assembly. The two ends of the knife shaft 2 are horizontally mounted on the frame body 1 through a bearing seat. The chopping knife 3 is installed on the end of the knife shaft 2 by bolts. The chopping knife 3 rotates and passes through a cutting port 104 that continuously outputs materials. The cutting port 104 is located between the feed trough 101 and the discharge trough 102. A debris box 103 for collecting meat and bone particles is arranged at the bottom of the cutting port 104. The important difference between the present utility model and the existing row chopping machine is that the counterweight assembly includes a counterweight tube 4, and a collar 401 is fixedly connected to the same side of both ends of the counterweight tube 4. The collar 401 can be rotatably sleeved on the cutter shaft 2, that is, there is a clearance fit between the collar 401 and the cutter shaft 2. The counterweight tube 4 is sealed at both ends, and one section can be opened. The inner cavity of the counterweight tube 4 is provided with counterweight particles and fillers, and the counterweight particles can be lead particles. The collar 401 is radially provided with a threaded hole and is threadedly connected with a top screw 402. The inner end of the top screw 402 is pressed tightly against the outer wall of the cutter shaft 2. A lock nut 403 is threadedly connected to the top screw 402. The lock nut 403 locks the top screw 402 on the outer wall of the collar 401 to prevent the top screw 402 from loosening.

[0031] By using the counterweight tube 4 as the main component of the counterweight, the mass adjustment of the counterweight can be achieved by changing the content of the counterweight particles in the tube cavity, which is very convenient to operate. By setting the collar 401 to be rotatably sleeved on the knife shaft 2, when the chopping knife 3 needs to be replaced, the angle of the counterweight tube 4 needs to be adjusted, the top screw 402 can be loosened, the counterweight tube 4 is slightly rotated to adjust the angle, and the top screw 402 is locked again to detect whether the dynamic balance is controlled within a reasonable range. If it is not appropriate, continue to adjust the angle of the counterweight tube 4. The utility model of the meat chopping machine is convenient for on-site debugging after reinstalling the chopping knife, which improves the quality and efficiency of the knife replacement operation.

[0032] In a specific implementation of this embodiment, Figure 3 As shown, there are two threaded holes on the collar 401, which are symmetrically arranged on both sides of the center line of the counterweight tube 4 and the knife shaft 2 and on the side away from the counterweight tube 4. Correspondingly, there are two sets of top screws 402 and lock nuts 403.

[0033] Obviously, the number of sets of the top screw 402 assembly can be one set or three sets, and a reasonable arrangement can tighten the collar 401 on the knife shaft 2 to prevent the counterweight tube 4 from angularly deflecting relative to the knife shaft 2. Similar simple variations fall within the protection scope of the present utility model.

[0034] In a specific implementation of this embodiment, Figure 3As shown, the knife shaft 2 is provided with a limiting ring groove 201 at the position of the collar 401 . The cross section of the limiting ring groove 201 is rectangular, and the inner end of the top screw 402 abuts against the bottom surface of the limiting ring groove 201 .

[0035] Specifically, if Figure 3 As shown, an axial anti-loosening tooth pattern is arranged on the bottom surface of the limiting ring groove 201, and the inner end diameter of the top screw 402 is more than twice the pitch of the tooth pattern.

[0036] By setting a limiting ring groove 201 on the knife shaft 2, the inner end of the top screw 402 abuts against the bottom surface of the limiting ring groove 201, which can prevent the ring 401 from axially moving relative to the knife shaft 2; by setting an anti-loosening tooth-shaped pattern on the bottom surface of the limiting ring groove 201, the ring 401 can be prevented from circumferential rotational dislocation relative to the knife shaft 2.

[0037] Example 2

[0038] like Figure 4 As shown, if the chopping machine stops, the stop position of the knife shaft 2 makes the chopping knife 3 stop at the cutting opening 104, the feeding mechanism will push the meat material to the chopping knife 3, causing damage to the chopping knife 3. Or the chopping knife 3 stops just above the cutting opening 104, which will cause the initial speed of the chopping knife 3 to be low when it contacts the harder frozen meat, avoiding the situation of cutting obstruction.

[0039] This embodiment is formed by improving the above-mentioned problem on the basis of the above-mentioned embodiment 1. A stop limit component is also provided on the knife shaft 2, and the stop limit component collects the stop position information of the knife shaft 2 and transmits it to the electric control system.

[0040] By setting the stop limit assembly on the cutter shaft 2, the angular position information of the cutter shaft 2 can be collected and the stop can be controlled by the electronic control system to ensure that the cutting knife 3 completely stops running when it is on the opposite side of the cutting opening 104.

[0041] Specifically, if Figure 4 and Figure 5 As shown, the stop limit assembly includes a stop ring 5 and a first proximity switch 6. The stop ring 5 is sleeved on the tail end of the cutter shaft 2. A protrusion 502 is provided on the outer wall of the stop ring 5. The first proximity switch 6 is installed on the frame body 1 through a mounting plate frame 601. The first proximity switch 6 is located directly below the stop ring 5 and can collect the passing signal of the protrusion 502. When the electric control system collects the passing signal of the protrusion 502 of the first proximity switch 6, the cutter shaft 2 is braked, and the cutter shaft 2 stops the cutting row cutter 3 on the opposite side of the cutting opening 104. The brake of the cutter shaft 2 can be achieved by a brake motor.

[0042] Through the setting of the machine sleeve ring 5 and the first proximity switch 6, the first proximity switch 6 collects the signal of the protrusion 502 passing by. The angular position relationship between the protrusion 502 and the chopping knife 3 can ensure that when the first proximity switch 6 collects the signal of the protrusion 502, the chopping knife 3 is located on the opposite side of the cutting opening 104.

[0043] Specifically, if Figure 4 As shown, a screw plug 501 is threadedly connected to the stop ring sleeve 5 , and the screw plug 501 is in the form of a hexagonal countersunk head, and the inner end of the screw plug 501 is tightly pressed against the outer wall of the cutter shaft 2 .

[0044] By using a countersunk screw as the screw plug 501 , it is possible to prevent the bolt head from protruding onto the outer wall of the shutdown ring sleeve 5 , thereby preventing the first proximity switch 6 from erroneously collecting data.

[0045] In a specific implementation of this embodiment, Figure 4 and Figure 5 As shown, the utility model steak chopping machine also includes a deceleration ring sleeve 7 and a second proximity switch 8. The deceleration ring sleeve 7 is also sleeved on the tail end of the knife shaft 2 and has the same structure as the shutdown ring sleeve 5. A bump is also provided on the outer wall of the deceleration ring sleeve 7. The second proximity switch 8 is also installed on the mounting plate frame 601. The second proximity switch 8 is located below the deceleration ring sleeve 7 and can collect information about the bump passing thereon. The bump of the deceleration ring sleeve 7 first passes through the second proximity switch 8, and the bump 502 then passes through the first proximity switch 6, and the two bumps are staggered at a certain angle. The electronic control system collects the signal of the second proximity switch 8 and starts to control the deceleration of the knife shaft 2.

[0046] By adding the deceleration ring 7 and the second proximity switch 8, the electric control system can be notified to start controlling the deceleration of the cutter shaft 2 before the first proximity switch 6 collects the signal of the bump 502 passing by. The specific deceleration method can be achieved by a brake motor or an independently set brake. After deceleration, when the first proximity switch 6 sends a signal, rapid braking can be achieved to avoid inaccurate stopping position of the cutting knife 3 due to inertial rotation.

[0047] In summary, by using the counterweight tube 4 as the main component of the counterweight, the mass adjustment of the counterweight can be achieved by changing the content of the counterweight particles in the tube cavity, which is very convenient to operate. By setting the collar 401 to be rotatably sleeved on the knife shaft 2, when the chopping knife 3 needs to be replaced, the angle of the counterweight tube 4 needs to be adjusted, the top screw 402 can be loosened, the counterweight tube 4 is slightly rotated to adjust the angle, and the top screw 402 is locked again to detect whether the dynamic balance is controlled within a reasonable range. If it is not appropriate, continue to adjust the angle of the counterweight tube 4. The utility model of the meat chopping machine is convenient for on-site debugging after reinstalling the chopping knife, which improves the quality and efficiency of the knife changing operation. In addition, by setting the limiting ring groove 201 on the knife shaft 2, the inner end of the top screw 402 abuts against the bottom surface of the limiting ring groove 201, which can prevent the collar 401 from axially moving relative to the knife shaft 2; by setting the anti-loosening tooth pattern on the bottom surface of the limiting ring groove 201, the collar 401 can be prevented from circumferential rotation dislocation relative to the knife shaft 2. By setting the stop limit assembly on the cutter shaft 2, the angular position information of the cutter shaft 2 can be collected and the stop can be controlled by the electronic control system, ensuring that the chopping cutter 3 stops running completely when it is on the opposite side of the cutting opening 104. By setting the machine sleeve ring 5 and the first proximity switch 6, the first proximity switch 6 collects the signal of the protrusion 502 passing by. The angular position relationship between the protrusion 502 and the chopping cutter 3 can ensure that when the first proximity switch 6 collects the signal of the protrusion 502, the chopping cutter 3 is located on the opposite side of the cutting opening 104. By using the countersunk screw form of the screw plug 501, it can be avoided that the bolt head protrudes onto the outer wall of the stop ring sleeve 5, and the fault of the first proximity switch 6 collecting the wrong information can be avoided. By adding the deceleration ring sleeve 7 and the second proximity switch 8, it can be possible to first notify the electronic control system to start controlling the deceleration of the cutter shaft 2 before the first proximity switch 6 collects the signal of the protrusion 502 passing by. After deceleration, when the first proximity switch 6 sends a signal, rapid braking can be achieved to avoid the inaccurate stop position of the chopping cutter 3 caused by inertial rotation.
