[0034] In a meat cutting machine of the present invention, in order to solve the problem that meat blocks are easily stuck in the knife group when cutting, the direction of rotation of the blades of the two knife groups during operation is limited; Figure 2 Looking from the direction A, the rotation direction of the blades of the strip cutting knife group is clockwise. When the meat piece enters from the left end, the part that first contacts the blades is subjected to the upward force of the blades due to the rotation direction of the blades. In addition, the entire strip cutting knife group will give the meat piece an overall rightward force during the cutting process, which is easier to cut than the counterclockwise rotation.

[0036] like Figure 2 As shown in FIG, the small reduction pulley 12 and the secondary large pulley 21 are on the same plane, and the two pulleys are connected by a belt, which can transmit power to the secondary transmission mechanism 2. Figure 2 Looking from the direction A, the secondary large pulley 21 turns clockwise.

The display part is located at Figure 2 The dotted area shown has a viewing angle direction opposite to direction B; Figure 4 for Figure 3 A cross-sectional view of the three-dimensional figure shown.

[0038] As mentioned above, after the belt transmission, the rotation direction of the secondary large pulley 21 is clockwise when viewed from the direction A.

The bearing seat is installed on the machine body and is responsible for positioning the entire shaft system. Figure 2 When viewed from the direction of A, the secondary transmission shaft 23 and all movable parts on the shaft rotate clockwise. Figure 3 From the perspective of , the secondary transmission shaft 23 and all movable parts on the shaft also rotate clockwise.

[0039] like Figure 3 , Figure 4 As shown, the secondary gear A22 is meshed with the slicing spur gear 31. After the gears are meshed, the rotation directions of the two gears are opposite. Therefore, when viewed from the direction A, the rotation direction of the slicing spur gear 31 is counterclockwise. Figure 3In the perspective shown, the slicing spur gear 31 also rotates counterclockwise; the slicing spur gear 31 is installed on the slicing driving shaft 32, and there is a bearing seat on each side of the slicing spur gear 31, which is sleeved on the slicing driving shaft 32, and the bearing seat is installed on the machine body to achieve its positioning.

[0043] When the clutch transmission mechanism 3 of the slicing knife group is in operation, Figure 3 , 4 5. As mentioned above, the direction of rotation of the slicing spur gear 31 is counterclockwise when viewed from the direction A, so the direction of rotation of the slicing driving shaft 32 and all movable parts on the shaft is counterclockwise; the slicing fixed end clutch 331 serves as the driving end, and naturally drives the driven section to rotate during operation, so the tooth helix of the fixed end clutch 331 and the slicing sliding end clutch 332 is a right helix.

[0045] The slicing end stopper 335 has two limiting gears, the gear close to the machine body is called the inner side, and the gear far from the machine body is called the outer side.

[0046] One end of the slice clutch lever 333 is Y-shaped and is stuck in the annular groove of the slice sliding end clutch 332. Figure 5 There is a clearer presentation in Fig.11 As shown in (a), one end of the slice axial retainer 53 is sleeved on the cylindrical shaft of the slice clutch lever 333, and the square column of the slice clutch lever 333 is placed on the slice retainer 54. Both retainers are fixed to the machine body. When the slice clutch lever 333 moves, it can only move in a single degree of freedom along the direction of the arrow; in other detailed display diagrams including the slice clutch lever 333, such as Figure 3 , 4 In FIG. 5 , in order to demonstrate the working principle as concisely as possible, the slice axial retainer 53 and the strip retainer 54 are not shown.

[0047] The circular ring at the end of the slicing clutch handle 334 at the other end is sleeved on the smooth rod of the slicing clutch lever 333. There is a through groove in the middle of the slicing clutch handle 334, which is limited on the base A336 by a metal straight stick, and the end is stuck in the slicing end limiter 335. The base A336 and the slicing end limiter 335 are both fixedly installed on the machine body; when working, the slicing clutch handle 334 can be stuck in one of the two grooves of the limiter by bending it according to the user's needs. During the bending process, the slicing clutch handle 334 will move along the axis of the round rod of the slicing clutch lever 333. The base A 336 has a wide groove, and will not be restricted by the position of the base A 336 when the handle is bent to change gears.

[0048] When the slicing clutch 33 is working, that is, when the slicing fixed end clutch 331 drives the slicing sliding end clutch 332 to rotate, the spring A 337 is in the maximum extension state, and the corresponding slicing clutch handle 334 should be stuck in the outer gear position, such as Figure 6 As shown, that is, in the outer groove A 3351; because in this working state, the spherical stopper A 3331 drives the ring to generate an inward pulling force on the end of the slicing clutch handle 334, so a groove is provided on the upper surface of the outer side of the slicing end stopper 335, that is, the outer groove A 3351 is formed, and the groove can generate an inward force on the slicing clutch handle 334, and the base A 336 is used as a fulcrum therein, so as to achieve force balance, so the outer groove A 3351 is provided on the upper surface of the outer side of the slicing end stopper 335; as shown Figure 3 , 5 It can more intuitively demonstrate its working principle.

[0049] When the slicing clutch 33 is not working, that is, the slicing fixed end clutch 331 is disengaged from the slicing sliding end clutch 332, it is necessary to clamp the handle in the inner groove A3352 of the slicing end stopper 335 by bending it. Figure 6 As shown, the inner groove A3352 is provided on the upper surface of the inner side of the slicing end stopper 335; under the support of the base A, the end ring of the slicing clutch handle 334 will pull the slicing clutch lever 333 outward under the action of the spherical stopper A3331, thereby driving the slicing sliding end clutch 332 to compress the spring A337, and the compression force of the spring A337 causes the slicing clutch handle 334 to be stuck in the inner groove A3351 of the slicing end stopper 335; Figure 3 , 5 It can more intuitively demonstrate its working principle.

[0050] The above force analysis can effectively prevent the handle from being out of gear due to factors such as vibration when the equipment is running.

[0051] When the slice clutch 33 is working, that is, the slice fixed end clutch 331 is engaged with the slice sliding end clutch 332, the slice driven shaft 34 and the movable parts on the shaft will rotate counterclockwise when viewed from the direction A. Figure 4 In the case of bevel gear A35 rotating from right to left, bevel gear A35 meshes with bevel gear B36. Figure 4 The middle bevel gear B36 rotates counterclockwise, and the bevel gear B36 will eventually drive the slicing knife group to rotate; Figure 4 The viewing direction and Figure 2 The A direction is opposite, so in Figure 4 Looking from the A direction, the bevel gear B36 will eventually drive the slicing knife group to rotate clockwise. This completes the description of the slicing transmission part.

[0052] like Figure 3 , Figure 4 As shown above, Figure 3 The secondary transmission shaft 23 and all movable parts on the shaft are clockwise. The secondary gear B24 is meshed with the spur gear A41. After the gears are meshed, the two gears rotate in opposite directions. Therefore, from the direction A, the spur gear A41 rotates counterclockwise. Figure 3 In the perspective shown, the direction of the slit spur gear A41 is also counterclockwise; the slit spur gear A41 is installed on the slit driving shaft 42, and there is a bearing seat on each side of the slit spur gear A41, which is sleeved on the slit driving shaft 42, and the bearing seat is installed on the machine body to achieve its positioning.

[0053] A strip cutting fixed end clutch 431 is installed at the end of the strip cutting driving shaft 42. This part is connected to the strip cutting driving shaft 42 through a key connection to achieve circumferential positioning, and an axial end baffle is screwed into the strip cutting driving shaft 42 through a screw to axially fix the two.

[0054] When the clutch transmission mechanism 4 of the slitting knife group is in operation, Figure 3 , 4 , 5. The above mentioned Figure 2 A direction and Figure 3 From the perspective of , the direction of rotation of the strip cutting spur gear A41 is counterclockwise, so the direction of rotation of the strip cutting driving shaft 42 and all movable parts on the shaft is counterclockwise; the strip cutting fixed end clutch 431 serves as the driving end, and naturally drives the driven section to rotate during operation, so the tooth helix of the strip cutting fixed end clutch 431 and the strip cutting sliding end clutch 432 is a left helix. After engagement, the circumferential force generated by the radial surface contact drives the driven section to rotate.

[0055] The strip cutting driven shaft 44 has a strip cutting sliding end clutch 432, a spring B 437, a bearing seat, a strip cutting spur gear B45, and a bearing seat installed thereon in sequence, wherein the strip cutting sliding end clutch 432 is connected to the strip cutting driven shaft 44 for circumferential positioning by a key connection, and is not fixed axially, and the strip cutting sliding end clutch 432 can slide within a range on the end shaft section of the strip cutting driven shaft 44.

[0056] The strip end stopper 435 has two limiting gear positions, the gear position close to the machine body is called the inner side, and the gear position far from the machine body is called the outer side.

[0057] One end of the strip cutting clutch lever 433 is in a Y shape (a lever), which is stuck in the annular groove of the strip cutting sliding end clutch 432. Figure 8 There is a more intuitive display in Fig.11 As shown in (b), one end of the slitting axial retainer 51 is sleeved on the cylindrical shaft of the slitting clutch lever 433, and the square column of the slitting clutch lever 433 is placed on the slitting retainer 52. Both retainers are fixed to the machine body. When the slitting clutch lever 433 moves, it can only move with a single degree of freedom along the direction of the arrow; in other detailed display diagrams including the slitting clutch lever 433, such as Figure 3 , 4 In FIG. 8 , in order to demonstrate the working principle as concisely as possible, the slit axial retainer 51 and the slit retainer 52 are not shown.

[0058] The details of the strip clutch lever 433 are shown in the figure below. Fig.10 As shown, the spherical stopper B4331, the recess 4332 and the screw head 4333 are its three main characteristic parts; the circular ring at the other end of the strip cutting clutch handle 434 is sleeved on the recess 4332 of the strip cutting clutch lever 433, and there is also a through groove in the middle of the strip cutting clutch handle 434, which is limited on the base B436 by a metal straight stick, and the end is stuck in one of the gears of the strip cutting end limiter 435, and the base B 436 and the strip cutting end limiter 435 are also fixedly installed on the body; when working, the strip cutting clutch handle 434 can be stuck in one of the two gears of the limiter by bending it according to the user's use needs. During the bending process, the strip cutting clutch handle 434 will move along the axis of the round rod of the strip cutting clutch lever 433, and the base B 436 has a wide groove, and will not be restricted by the position of the base B 436 during the process of bending the handle to change the gear.

[0059] When the strip cutting clutch 43 is working, that is, when the strip cutting fixed end clutch 431 drives the strip cutting sliding end clutch 432 to rotate, the spring B 437 is in the maximum extension state, and the corresponding strip cutting clutch handle 434 should be stuck on the inner side of the limiter, such as Fig. 9As shown, that is, in the inner groove B 4352; because in this working state, the spherical stopper B 4331 generates an outward thrust on the end ring of the slicing clutch handle 334, a groove is provided on the inner lower surface of the slicing end stopper 435, that is, the inner groove B 4352, which can generate an outward force on the slicing clutch handle 434, and the base A336 acts as a fulcrum therein, thereby achieving force balance, as shown in FIG. Figure 3 , 8 The working principle can be more intuitively demonstrated; therefore, the inner groove B 4352 is disposed on the inner lower surface of the cut end stopper 435 . When the slitting clutch 43 is not working, that is, the slitting fixed end clutch 431 is disengaged from the slitting sliding end clutch 432, the handle needs to be moved to clamp it in the groove B 3351 outside the slitting end stopper 435, as shown in FIG. Fig. 9 As shown, the outer groove B 4351 is provided on the lower surface of the outer side of the strip cutting end stopper 435; under the support of the base A, the end ring of the strip cutting clutch handle 434 will push the strip cutting clutch lever 433 inward under the action of the spherical stopper B 4331, thereby driving the strip cutting sliding end clutch 432 to compress the spring B 437, and the compression force of the spring B 437 causes the strip cutting clutch handle 434 to be stuck in the outer groove B 4351 of the strip cutting end stopper 435, as shown in FIG. Figure 3 , 8 It can more intuitively demonstrate its working principle.

[0060] The above force analysis can effectively prevent the handle from being out of gear due to factors such as vibration when the equipment is running.

[0061] like Figure 3 , 4 As shown in the above, when the strip cutting clutch 43 is working, the direction of the strip cutting spur gear B 45 is counterclockwise, because the strip cutting spur gear B 45 is engaged with the reversing gear 46, driving the reversing gear 46 to rotate, so Figure 3 The viewing angles and Figure 2 From the direction A, the reversing gear 46 rotates clockwise because the reversing pulley 48 is connected to the strip cutting pulley 49 through a belt transmission. Figure 1 The working principle can be more intuitively demonstrated. According to the above analysis, the reversing pulley 48 turns clockwise, and after the belt transmission, the slitting pulley 49 also turns clockwise; because the slitting pulley 49 is the driving pulley that drives the slitting knife group to rotate, the above analysis proves that the transmission system can realize the clockwise rotation of the slitting knife group. The description of the slitting transmission part is now complete.

[0062] Back to Figure 3 In the above, the rotation direction of the secondary small pulley 25 is clockwise; Figure 2As can be seen in the figure, the secondary small pulley 25 and the conveyor belt pulley A 26 are connected by belt transmission, so from the direction A, the secondary small pulley 25 and the conveyor belt pulley A 26 are both clockwise, so Figure 2 The conveyor belt on the right side of the view also rotates clockwise, so that the cut meat slices or strips can be conveyed out; there is also a pulley at the other end of the shaft where the conveyor belt pulley A 26 is located, that is, Figure 1 The conveyor belt pulley B 27 shown in the figure is connected to the conveyor belt pulley C 28 through a belt drive. Figure 1 In the viewing angle, both pulleys are turning counterclockwise. The conveyor pulley C 28 is Figure 1 The drive wheel of the conveyor belt on the right side, so Figure 1 The conveyor belt on the right side of the view rotates counterclockwise. Users can place meat pieces on it, which will be transported to the middle cutting position via the input track and then output by the output track after cutting.
