The driving chain 12 is wound between the driving sprocket 10 and the driven sprocket 11. When the sprocket drive motor 9 is started, the driving sprocket 10 can be driven to rotate. The driving sprocket 10 drives the driven sprocket 11 to rotate through the driving chain 12. The driven sprocket 11 can drive the corresponding rotating shaft 6 to rotate, thereby driving the two feeding chains 5 to rotate, thereby achieving the effect of driving multiple material boxes 2 to reciprocate and transport them to the cutting mechanism.

[0029] Among them, refer to Figure 4 , Figure 5Two parallel cutting shafts 14 are rotatably arranged below the mounting frame 13. The two cutting shafts 14 are both horizontally arranged, and the length directions of the two cutting shafts 14 are perpendicular to the feeding direction of the feeding mechanism. A plurality of blades 3 are sleeved at intervals on each cutting shaft 14. The blades 3 are circular as a whole, and the cutting surface of each blade 3 is perpendicular to the length direction of the cutting shaft 14.

The ends of the two cutting shafts 14 away from the driven pulley 17 are coaxially connected with a transmission sprocket 19, a transmission chain 20 is wound between the two transmission sprockets 19, and a driving belt 18 is wound between the driving pulley 16 and the driven pulley 17; start the cutting drive motor 15, the cutting drive motor 15 will drive the driving pulley 16 to rotate, the driving pulley 16 drives the driven pulley 17 and the corresponding cutting shaft 14 to rotate through the driving belt 18, and the cutting shaft 14 drives the other cutting shaft 14 to rotate through the transmission chain 20, so that the multiple blades 3 on the two cutting shafts 14 can rotate at high speed to achieve cutting.

[0030] In addition, the two feeding chains 5 each include an upper chain segment and a lower chain segment, and a support plate is provided on the upper chain segment of each feeding chain 5 and the frame 1 below the lower chain segment (the support plate is not shown enlarged in the accompanying drawings), and the length direction of the support plate is consistent with the feeding direction of the feeding mechanism, and a support groove is provided on each support plate, and the corresponding chain segment of each feeding chain 5 is located in the support groove of the corresponding support plate, so that when the blade 3 squeezes and cuts the bones and flesh in the lower material box 2, the support plate can support the upper feeding chain 5 and the material box 2, and can prevent the bones and flesh from shifting downward due to the downward bending of the corresponding part of the chain to a certain extent.

[0031] In other embodiments, the feeding mechanism may also adopt a feeding chain 5, and placement plates are provided on the frame 1 on both sides of the feeding chain 5 along the feeding direction of the feeding mechanism. The placement plates extend along the feeding direction of the feeding mechanism, and the feeding chain 5 is set in the middle position of the multiple material boxes 2, and then the two ends of the multiple material boxes 2 are placed on the placement plates on the corresponding sides, so as to maintain stable support for the multiple material boxes 2 through the two placement plates.

[0032] In other embodiments, reference Figure 4 , Figure 5 A material limiting mechanism is provided on the frame 1, and the material limiting mechanism includes a grate structure. The grate structure is located on the frame 1 above the material box 2. A gap is opened on the grate structure for the blade 3 to pass downward. The grate structure is used to block the upper opening of the material box 2 passing under the grate structure.

[0033] Specifically, refer to Figure 4 , Figure 5 The grate structure includes two mounting bars 21 and a plurality of limiting bars 22. The two mounting bars 21 are arranged on the mounting frame 13 in parallel and at intervals by bolts. The length directions of the two mounting bars 21 are perpendicular to the feeding direction of the feeding mechanism. One mounting bar 21 is located at one end of the plurality of blades 3 close to the discharge end of the feeding mechanism, and the other mounting bar 21 is located at one end of the plurality of blades 3 away from the discharge end of the feeding mechanism. The plurality of limiting bars 22 are arranged between the two mounting bars 21 by bolts. The plurality of limiting bars 22 are parallel to each other, and the length directions of the plurality of limiting bars 22 are consistent with the feeding direction of the feeding mechanism. A space for the corresponding blades is left between two adjacent limiting bars 22. 3 passes downward, and this spacing 23 is the gap mentioned above. Only one blade 3 passes through each spacing 23; when the material box 2 carrying bones and flesh passes under the multiple limiting bars 22, the multiple limiting bars 22 can limit the bones and flesh in the material box 2, which can prevent the bones and flesh from escaping from the material box 2 during the cutting process to a certain extent, and when the bones and flesh are stuck on the blade 3, the grate structure can separate the bones and flesh from the blade 3 to prevent the blade 3 from carrying the bones and flesh and rotating with the blade 3. The bones and flesh are easily damaged by the blade 3 on the other set of cutting shafts 14 when rotating at a high speed with the blade 3, and the bones and flesh may be thrown over the body during the high-speed rotation and cause harm to the surrounding personnel.

[0034] More specifically, refer to Figure 4 , Figure 5, a height adjustment member is provided between each limit bar 22 and the corresponding mounting bar 21, and the height adjustment member is used to adjust the distance between the corresponding limit bar 22 and the two mounting bars 21 in the vertical direction, and the height adjustment member includes two adjusting bolts 24 and two locking nuts 25; both ends of the plurality of limit bars 22 are provided with through holes 26, and the two mounting bars 21 are provided with a plurality of through threaded holes 27; firstly, the rod of the adjusting bolt 24 is passed through the through hole 26 of the limit bar 22, and then a locking nut 25 is sleeved on the adjusting bolt 24, so that the limit bar 22 is located between the locking nut 25 and the head of the adjusting bolt 24, and it is noted that the locking nut 25 should not be locked on the limit bar 22 at the beginning, and then the rods of the two adjusting bolts 24 are inserted from the corresponding threaded holes 27 on the two mounting bars 21 below, And the two adjusting bolts 24 are threadedly connected with the threaded holes 27 on the corresponding mounting strips 21, so that the initial fixation of the adjusting bolts 24 bodies can be achieved; then the two locking nuts 25 are screwed so that the two locking nuts 25 and the heads of the corresponding adjusting bolts 24 clamp the corresponding ends of the limit strips 22, so that the fixation of the limit strips 22 can be achieved; the thickness of bones is different, so it is necessary to adjust the distances between multiple limit strips 22 and the material box 2 according to the thickness of the bones and flesh. When the height of the limit strip 22 needs to be adjusted, first loosen the locking nut 25, and then rotate the adjusting bolt 24 so that the adjusting bolt 24 moves upward or downward on the mounting strip 21. The upward or downward movement of the adjusting bolt 24 will drive the limit strip 22 to move upward or downward synchronously, and then tighten the locking nut 25 again to lock the limit strip 22 again.

[0035] In addition, refer to Figure 4 , Figure 5 After the rod of the adjusting bolt 24 passes upward through the mounting strip 21 , a washer 28 and a safety nut 29 are sleeved thereon. The safety nut 29 presses the washer 28 against the corresponding mounting strip 21 , thereby achieving secondary fixation of the adjusting bolt 24 .

[0036] In addition, refer to Figure 4 , Figure 5 , multiple limit bars 22 include a horizontal section 30, two inclined sections 31 and two mounting sections 32. An upwardly inclined inclined section 31 is provided at both ends of the horizontal section 30, and a horizontally arranged mounting section 32 is provided at one end of the two inclined sections 31 away from the horizontal section 30. The above-mentioned horizontal and inclined refer to the relative to the horizontal ground after the grate structure is installed on the mounting frame 13; a through hole 26 is provided on the two mounting sections 32. The purpose of the upward structure at both ends of the limit bar 22 is to reduce the obstruction of the adjusting bolts 24 at both ends of the limit bar 22 on the bones and flesh passing below.

[0037] In other embodiments, reference Figure 3 , Figure 4 , Figure 5 The blade 3 is close to the discharge end of the chain feeding mechanism, and a chain limiting mechanism is arranged at the position of the frame 1 close to the discharge end of the chain feeding mechanism. The chain limiting mechanism includes a chain pressing plate 33, and the chain pressing plate 33 is located above the feeding chain 5. The chain pressing plate 33 is used to limit the feeding chain 5 on the sprocket. The two feeding chains 5 are each provided with a chain pressure plate 33 near the discharge end of the feeding mechanism. The upper part of the chain pressure plate 33 is detachably arranged on the mounting frame 13 above the frame 1 by a plurality of bolts, and the lower part confines the corresponding feeding chain 5 on the corresponding support plate, and further confines the two feeding chains 5 on the corresponding feeding sprocket 7. In fact, in the process of the blade 3 squeezing and cutting the bones and flesh in the material box 2, the stress conditions of the bones and flesh will keep changing as the material box 2 moves, resulting in uneven stress on the material box 2. For example, when the rear side of the material box 2 is stressed, the front side of the material box 2 is prone to tilt up, thereby driving the feeding chain 5 below to tilt up. The chain limiting mechanism can conveniently prevent the feeding chain 5 from tilting up, thereby preventing the equipment and the blade 3 from contacting the chain and being damaged.

[0038] Example 2

[0039] Based on Example 1, in this example, reference Figure 2 , Figure 3 , a partition 34 is provided in each of the plurality of material boxes 2, and the partition 34 divides the material box 2 into a splitting box 35 and a dicing box 36; a passage slot 4 is provided on the side wall of the splitting box 35, and a plurality of passage slots 4 are provided on the side wall of the dicing box 36; the cutting mechanism comprises a plurality of blades 3, and the total number of the passage slots 4 on the splitting box 35 and the dicing box 36 is the same as the number of the blades 3, and all the passage slots 4 on each material box 2 correspond to the plurality of blades 3 one by one; the inner bottom walls of the splitting box 35 and the dicing box 36 are provided with cutting slots 37 for cooperating with the blades 3 to cut bones and meat. Placing smaller bones and meat such as chicken legs in the splitting box 35 can conveniently cut the chicken legs in half directly, while placing larger bones and longer bones in the dicing box 36 can facilitate cutting the bones into multiple pieces by the plurality of blades 3.

[0040] Example 3

[0041] Based on Example 2, in this example, refer to Figure 2 , Figure 3The split half box 35 is provided with a detachable fixture, which is used to confine the bone and meat in the split half box 35; the fixture includes two fixtures, which have the same structure and shape, and the fixture includes a base 38, a clamping plate 39 and an expansion plate 40 arranged in sequence from bottom to top, a through mounting hole 41 is provided on the base 38, and bolt holes 42 are provided on both sides of the inner bottom wall of the split half box 35 along the feeding direction of the feeding mechanism, and the bolt holes 42 are provided with internal threads, and the bases 38 of the two fixtures are installed on the corresponding sides of the inner bottom wall of the split half box 35 by bolts, and the upper parts of the clamping plates 39 of the two fixtures shrink toward the middle of the split half box 35 and are used to clamp the bone and meat such as chicken legs, and the expansion plates 40 on the tops of the two fixtures extend and expand toward the outside of the split half box 35, so as to facilitate pressing the chicken legs into between the two clamping plates 39 through the two expansion plates 40. The fixture can be made of elastic metal material, such as a thin stainless steel plate. The chicken legs and other bones and meat can be confined in the splitting box 35 by the clamping plate to prevent the chicken legs from being offset when the blade 3 cuts the chicken legs, thereby causing the blade 3 to cut crookedly.

[0042] In other embodiments, reference Figure 4 , Figure 6 A spacing 23 adjusting member is provided on the frame 1 near one end of the chain, and the spacing 23 adjusting member is used to adjust the spacing 23 between the feeding sprockets 7 at both ends of the feeding chain 5. The spacing 23 adjusting member can be used to conveniently adjust the tension of the feeding chain 5. In this embodiment, since two feeding chains 5 are provided, two spacing 23 adjusting members are also provided, and the spacing 23 adjusting members are used to adjust one feeding chain 5 respectively.

[0043] Specifically, refer to Figure 4 , Figure 6A fixing plate 43 is provided on the frame 1 beside each feeding chain 5, and a fixing column 44 is provided on one side of the fixing plate 43 close to the discharge end of the feeding mechanism; the spacing 23 adjustment member includes an adjustment block 45, an adjustment screw 46 and an adjustment nut 47, a through notch 48 is provided on the fixing plate 43 in the horizontal direction, and a slide groove 49 is provided on the upper and lower surfaces of the adjustment block 45, the adjustment block 45 is located in the notch 48 of the fixing plate 43, and the upper wall of the notch 48 of the fixing plate 43 is located in the slide groove 49 above the adjustment block 45, and the lower wall of the notch 48 is located in the slide groove 49 below the adjustment block 45, and the adjustment block 45 and the fixing plate 43 are slidably matched; a fixing groove 50 is provided on the surface of the adjustment block 45, and the fixing groove 50 A through hole 51 is provided on one side wall near the corresponding fixed column 44, and a through hole 5226 is provided on the fixed column 44. One end of the adjusting screw 46 passes through the through hole 5226 and the through hole 51 in sequence and then extends into the fixed groove 50. The inner diameter of the through hole 5226 is larger than the outer diameter of the adjusting screw 46. A fixing nut 53 is fixedly welded on one end of the adjusting screw 46 located inside the fixed groove 50. The adjusting nut 47 is sleeved on the adjusting screw 46. The adjusting nut 47 is located on the rod section of the adjusting screw 46 between the adjusting block 45 and the fixed column 44, and the adjusting nut 47 is tightly pressed against the outer wall of the fixed column 44 away from the feeding direction of the feeding mechanism. The length direction of the adjusting screw 46 is consistent with the feeding direction of the feeding mechanism. Bearing holes are provided on both adjusting blocks 45, and both ends of the rotating shaft 6 are rotatably connected to the adjusting blocks 45 at the corresponding ends through bearings.

[0044] Reference Figure 4 , Figure 6 After the feeding chain 5 has been used for a period of time, it will wear out and make the feeding chain 5 loose. At this time, you can use pliers or other tools to clamp the fixing nut 53 so that it does not rotate, and use a wrench to twist the adjusting nut 47 on the other hand to make the adjusting nut 47 move in the direction away from the adjusting block 45. Since the fixing column 44 prevents the movement of the adjusting nut 47, the adjusting nut 47 has a tendency to move relative to the adjusting screw rod 46 toward the discharging end of the feeding mechanism, that is, the adjusting screw rod 46 has a tendency to move relative to the adjusting nut 47 away from the discharging end of the feeding mechanism. When the adjusting nut 47 is fixed, the adjusting screw rod 46 will drive the adjusting block 45 to move away from the discharging end of the feeding mechanism, thereby driving the rotating shaft 6 and the corresponding ends of the two feeding chains 5 to move toward an end away from the discharging end of the feeding mechanism. When the ends of the two feeding chains 5 close to the discharging end of the feeding mechanism are fixed, the tensioning of the two feeding chains 5 can be achieved.
