Description

Technical Field

[0001] This invention relates primarily to the field of food processing equipment technology, specifically a transmission system for a meat slicer. Background Technology

[0002] In specific settings such as restaurants and hotels, to meet the large demand for fresh meat in a short period of time, it is necessary to efficiently and quickly cut large quantities of fresh meat. Machine cutting can significantly improve the uniformity of meat cutting.

[0003] However, most existing meat slicers can only achieve a single meat-cutting method. As one of the existing patented technologies related to this type of meat slicer, the meat slicer for chilled fresh meat quantitative cutting disclosed in the existing patent application number 201980078440.X (hereinafter referred to as the prior art) is a representative example.

[0004] In existing technologies including but not limited to those described above, meat pieces are placed in the slot of a meat slicer, compressed to a specified volume, and then extruded through an outlet to be cut, followed by rotational cutting by a cutting blade.

[0005] It can be observed that existing technologies mostly employ a single cutting method, which fails to meet users' needs when they require other cutting methods, such as cutting large pieces of meat into long strips in certain scenarios. The functionality of existing meat slicers still needs improvement. Summary of the Invention

Furthermore, the entire slicing unit exerts a force to the right on the meat throughout the cutting process, making it easier to cut compared to a counter-clockwise rotation. From... Figure 2 Looking at the B direction, the slicing blades rotate clockwise. This rotation also applies a force to the right to the meat, making it easier to cut compared to a counter-clockwise rotation. Therefore, this transmission system solves the rotation problem of two specific blade groups. Attached Figure Description

[0034] In a meat slicer of this invention, to address the problem of meat pieces easily getting stuck in the blade assembly during cutting, the rotation direction of the blades in the two blade assemblies is limited; from Figure 2 Looking at the center (A) direction, the blades of the slicing unit rotate clockwise. When the meat enters from the left, the part that first contacts the blade experiences an upward force due to the blade's rotation. Furthermore, the entire slicing unit exerts a force to the right on the meat throughout the cutting process, making it easier to cut compared to a counter-clockwise rotation. From... Figure 2 Looking at the center (B) direction, the slicing blades rotate clockwise. This rotation also applies a force to the right on the meat, making it easier to cut compared to a counter-clockwise rotation. A schematic diagram of the two blades is shown below. Figure 12 As shown, the left-hand blade assembly is a strip-cutting blade assembly, and the right-hand blade assembly is a slice-cutting blade assembly. The rotation axes of the two blade assemblies are perpendicular to each other.

[0035] From Figure 2Looking from direction A, the output shaft of the drive motor is set to rotate clockwise. A drive pulley is installed on the output shaft of the drive motor. The drive pulley is connected to the large reduction pulley 11 in the first-stage belt drive reduction mechanism 1 through a belt to transmit power, and the two pulleys are on the same plane. At this time, the rotation direction of the reduction drive shaft 13 is clockwise. The large reduction pulley 11 and the small reduction pulley 12 are respectively installed at both ends of the reduction drive shaft 13. There are also two bearing seats (bearing brackets) installed on the reduction drive shaft 13 between them. The bearing seats are responsible for fixing to the machine body, thereby realizing the positioning of the first-stage belt drive reduction mechanism 1 on the machine body.

[0036] like Figure 2 As shown, the small reduction pulley 12 and the large secondary 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. At this time, from Figure 2 Looking at direction A, the second-stage large pulley 21 rotates clockwise.

[0037] Figure 3 This is a 3D structural diagram of the transmission system, the core component of the meat slicer. The part shown is located at... Figure 2 The area shown by the dashed line has a view angle opposite to direction B. Figure 4 for Figure 3 The cross-sectional view of the 3D diagram shown.

[0038] As mentioned above, after belt drive, viewed from direction A, the rotation direction of the secondary large pulley 21 is clockwise. The secondary large pulley 21 is... Figure 3 , Figure 4 It was also displayed, in Figure 3 , Figure 4 In the view shown, the secondary drive shaft 23 is mounted from top to bottom with the following components: secondary large pulley 21, bearing housing, secondary gear A 22, secondary gear B 24, bearing housing, and secondary small pulley 25. The bearing housing, mounted on the machine body, is responsible for positioning the entire shaft system. Figure 2 Looking from direction A, the rotation of the secondary drive shaft 23 and all movable parts on the shaft is clockwise. This is explained for ease of understanding. Figure 3 From the perspective of the viewer, the rotation of the secondary drive shaft 23 and all movable parts on the shaft is also clockwise.

[0039] like Figure 3 , Figure 4 As shown, the secondary gear A22 meshes with the spur gear 31. After meshing, the two gears rotate in opposite directions. Therefore, viewed from direction A, the spur gear 31 rotates counterclockwise. Figure 3In the view shown, the slicing spur gear 31 rotates counterclockwise; the slicing spur gear 31 is mounted on the slicing drive shaft 32, and there is a bearing seat on each side of the slicing spur gear 31 that is fitted onto the slicing drive shaft 32. The bearing seats are mounted on the machine body to achieve positioning.

[0040] A jaw clutch is installed at the end of multiple shafts, and the jaw clutch is installed in multiple places in the device, and is referred to as a clutch throughout the text.

[0041] A slice fixing end clutch 331 is installed at the end of the slice drive shaft 32. This part is connected to the slice drive shaft 32 by a key connection to achieve circumferential positioning, and the two are axially fixed by a shaft end baffle screwed into the slice drive shaft 32.

[0042] The clutch used in this device has a helical cross section. When a pair of clutches are engaged, the axial surfaces of the two clutches will contact first, and finally the radial surfaces will also contact.

[0043] When the slicing blade assembly clutch transmission mechanism 3 is operating, see Figure 3 , 4 5. As mentioned above, the direction of rotation of the spur gear 31 when viewed from direction A is counterclockwise. Therefore, the direction of rotation of the spur gear 32 and all movable parts on the spur gear 32 is counterclockwise. The fixed end clutch 331 of the spur gear 331 is the driving end, and it naturally drives the driven section to rotate during operation. Therefore, the helix of the teeth of the fixed end clutch 331 and the sliding end clutch 332 of the spur gear 332 is right-hand helix. After engagement, the circumferential force generated by radial surface contact drives the driven section to rotate.

[0044] The slice driven shaft 34 is equipped with a slice sliding end clutch 332, springs A and 337, a bearing seat, bevel gear A and 35, and the bearing seat is mounted on it in sequence. The sliding end clutch 332 is circumferentially positioned to the slice driven shaft 34 by a key connection, and its axial direction is not fixed. The slice sliding end clutch 332 can slide within a range on the end section of the slice driven shaft 34.

[0045] The slice end limiter 335 has two limiting positions. The position closer to the machine body is called the inner side, and the position farther away from the machine body is called the outer side.

[0046] One end of the slicing clutch lever 333 is Y-shaped and engages within the annular groove of the slicing sliding end clutch 332. Figure 5 There is a clearer display in it; such as Figure 11 As shown in (a), one end of the axial retainer 53 is fitted onto the cylindrical shaft of the slicing clutch lever 333, and the square column of the slicing clutch lever 333 rests on the slicing retainer 54. Both retainers are fixed to the machine body. When the slicing clutch lever 333 moves, it can only move in a single degree of freedom along the direction of the arrow. Other detailed views including the slicing clutch lever 333 are shown in the figure below. Figure 3 , 4 In section 5, in order to demonstrate its working principle as concisely as possible, the slice axial holder 53 and slice holder 54 are not shown.

[0047] The ring at the end of the other end of the slice clutch handle 334 is fitted onto the smooth rod of the slice clutch lever 333. The slice clutch handle 334 has a through groove in the middle, which is limited to the base A336 by a straight metal rod. The end is locked in the slice end limiter 335. The base A336 and the slice end limiter 335 are both fixedly installed on the machine body. During operation, according to the user's needs, the slice clutch handle 334 can be moved to lock it in one of the two grooves of the limiter. During the movement, the slice clutch handle 334 will move around the axis of the round rod of the slice clutch lever 333. The base A336 has a wide groove, so the position of the base A336 will not be restricted during the shifting of gears.

[0048] When the slicer clutch 33 is working, that is, when the slicer fixed end clutch 331 drives the slicer sliding end clutch 332 to rotate, the spring A 337 is in its maximum extension state, and the corresponding slicer clutch handle 334 should be engaged in the outer gear position. Figure 6 As shown, the outer groove A 3351 is located within the outer groove. Because in this working state, the spherical stop A 3331 drives the ring to generate an inward pulling force on the end of the slice clutch handle 334, a groove is provided on the upper surface of the outer side of the slice end limiter 335, thus forming the outer groove A 3351. This groove can generate an inward force on the slice clutch handle 334. Furthermore, the base A 336 acts as a fulcrum within it, thereby achieving force balance. Therefore, the outer groove A 3351 is located on the upper surface of the outer side of the slice end limiter 335. Figure 3 , 5 It can more intuitively demonstrate its working principle.

[0049] When the slicing clutch 33 is not working, that is, when the slicing fixed end clutch 331 is disengaged from the slicing sliding end clutch 332, it is necessary to turn the handle to lock it into the inner groove A3352 of the slicing end limiter 335. Figure 6 As shown, the inner groove A3352 is located on the upper surface inside the slice end limiter 335; supported by the base A, the end ring of the slice clutch handle 334 will pull the slice clutch lever 333 outward under the action of the spherical stop block A3331, thereby driving the slice sliding end clutch 332 to compress the spring A337. The compression force of the spring A337 causes the slice clutch handle 334 to be stuck in the inner groove A3351 of the slice end limiter 335; as Figure 3 , 5 It can more intuitively demonstrate its working principle.

[0050] The above force analysis can effectively prevent the handle from disengaging from the gear position due to vibration and other factors during equipment operation.

[0051] When the slicer clutch 33 is engaged, i.e., the slicer fixed end clutch 331 and the slicer sliding end clutch 332 are engaged, viewed from direction A, it will drive the slicer driven shaft 34 and the movable parts on the shaft to rotate counterclockwise; Figure 4 In the middle, bevel gear A35 rotates from right to left because bevel gear A35 meshes with bevel gear B36, therefore Figure 4 The bevel gear B36 rotates counterclockwise, and ultimately drives the slicing blade assembly to rotate; because Figure 4 View direction and Figure 2 The direction of A is opposite, so in Figure 4 Looking at direction A, bevel gear B36 will eventually drive the slicing blade assembly to rotate clockwise. This concludes the explanation of the slicing transmission mechanism.

[0052] like Figure 3 , Figure 4 As shown above, in Figure 3 From the perspective of the secondary transmission shaft 23, the rotation direction of all movable parts on the shaft is clockwise. The secondary gear B24 meshes with the spur gear A41. After the gears mesh, the rotation directions of the two gears are opposite. Therefore, viewed from direction A, the rotation direction of the spur gear A41 is counterclockwise. Figure 3 In the view shown, the direction of rotation of the spur gear A41 is also counterclockwise; the spur gear A41 is mounted on the spur gear drive shaft 42, and there is a bearing seat on each side of the spur gear A41 on the spur gear drive shaft 42. The bearing seats are mounted on the machine body to achieve positioning.

[0053] A cutting strip fixed end clutch 431 is installed at the end of the cutting strip drive shaft 42. This part is connected to the cutting strip drive shaft 42 by a key connection to achieve circumferential positioning, and the two are axially fixed by a shaft end baffle screwed into the cutting strip drive shaft 42.

[0054] When the clutch transmission mechanism 4 of the slicing knife assembly is operating, see Figure 3 , 4 5. As mentioned above, from Figure 2 direction A and Figure 3 From the perspective of the cutting spur gear A41, the direction of rotation is counterclockwise, so the direction of rotation of the cutting drive shaft 42 and all movable parts on the shaft is counterclockwise; the cutting fixed end clutch 431, as the driving end, naturally drives the driven section to rotate during operation, so the helix of the cutting fixed end clutch 431 and the cutting sliding end clutch 432 is left-handed. After engagement, the radial surface contact generates circumferential force to drive the driven section to rotate.

[0055] The slicing driven shaft 44 is equipped with a slicing sliding end clutch 432, a spring B 437, a bearing seat, a slicing spur gear B45, and a bearing seat mounted on it. The slicing sliding end clutch 432 is circumferentially positioned to the slicing driven shaft 44 via a key connection, but its axial direction is not fixed. The slicing sliding end clutch 432 can slide within a range on the end section of the slicing driven shaft 44.

[0056] The strip-cutting end limiter 435 has two limiting positions: the position closer to the machine body is called the inner side, and the position farther away from the machine body is called the outer side.

[0057] One end of the cutting clutch lever 433 is Y-shaped (paddle), which is engaged in the annular groove of the cutting sliding end clutch 432. Figure 8 There is a more intuitive display; such as Figure 11 As shown in (b), one end of the axial retainer 51 is fitted onto the cylindrical shaft of the cutting clutch lever 433, and the square column of the cutting clutch lever 433 rests on the cutting retainer 52. Both retainers are fixed to the machine body. When the cutting clutch lever 433 moves, it can only move in a single degree of freedom in the direction of the arrow. Other detailed drawings including the cutting clutch lever 433 are shown in the figure. Figure 3 , 4 In section 8, in order to demonstrate its working principle as concisely as possible, the axial retainer 51 and the axial retainer 52 of the cutting strip are not shown.

[0058] Detailed image of the 433 cutting clutch lever is shown below. Figure 10 As shown, the spherical stop block B4331, the recess 4332, and the screw head 4333 are its three main characteristic parts; the ring at the other end of the cutting clutch handle 434 is fitted onto the recess 4332 of the cutting clutch lever 433, and the cutting clutch handle 434 also has a through groove in the middle, which is limited to the base B436 by a straight metal rod, and the end is locked in one of the positions of the cutting end limiter 435. The base B 436 and the cutting end limiter 435 are also fixedly installed on the machine body; during operation, according to the user's needs, the cutting clutch handle 434 can be moved to lock it in one of the two positions of the limiter. During the movement, the cutting clutch handle 434 will move around the axis of the round rod of the cutting clutch lever 433. The base B 436 has a wide groove, so the position of the base B 436 will not be restricted during the shifting of gears.

[0059] When the cutting clutch 43 is working, that is, when the cutting fixed end clutch 431 drives the cutting sliding end clutch 432 to rotate, the spring B 437 is in its maximum extension state, and the corresponding cutting clutch handle 434 should be locked inside the limiter. Figure 9As shown, that is, inside the inner groove B 4352; because the spherical stop block B 4331 generates an outward pushing force on the end ring of the slicing clutch handle 334 in this working state, a groove is provided on the lower inner surface of the slicing end limiter 435, that is, the inner groove B 4352. This groove can generate an outward force on the slicing clutch handle 434. In addition, the base A336 is called the fulcrum in it, thereby achieving force balance, as shown. Figure 3 , 8 This allows for a more intuitive demonstration of its working principle; therefore, the inner groove B 4352 is located on the lower inner surface of the strip end limiter 435.

[0060] When the cutting clutch 43 is not working, that is, when the cutting fixed end clutch 431 is disengaged from the cutting sliding end clutch 432, it is necessary to turn the handle to lock it in the groove B 3351 outside the cutting end limiter 435. Figure 9 As shown, the outer groove B 4351 is located on the lower surface outside the cutter end limiter 435; supported by the base A, the end ring of the cutter clutch handle 434 will push the cutter clutch lever 433 inward under the action of the spherical stop block B 4331, thereby driving the cutter sliding end clutch 432 to compress the spring B 437. The compression force of the spring B 437 causes the cutter clutch handle 434 to be locked in the outer groove B 4351 of the cutter end limiter 435, as shown. Figure 3 , 8 It can more intuitively demonstrate its working principle.

[0061] The above force analysis can effectively prevent the handle from disengaging from the gear position due to vibration and other factors during equipment operation.

[0062] like Figure 3 , 4 As mentioned above, when the cutting clutch 43 is working, the direction of rotation of the cutting spur gear B 45 is counterclockwise because the cutting spur gear B 45 meshes with the reversing gear 46, driving the reversing gear 46 to rotate. Figure 3 The perspective shown and Figure 2 Looking at direction A, the reversing gear 46 rotates clockwise because the reversing pulley 48 and the strip-cutting pulley 49 are connected by a belt drive. Figure 1 This more intuitively demonstrates its working principle. Based on the above analysis, the reversing pulley 48 rotates clockwise, and after belt drive, the cutting pulley 49 also rotates clockwise. Since the cutting pulley 49 is the drive pulley that rotates the cutting blade assembly, the above analysis proves that this transmission system can achieve clockwise rotation of the cutting blade assembly. This concludes the explanation of the cutting transmission section.

[0063] Back to Figure 3 In the above-mentioned text, the rotation direction of the secondary pulley 25 is clockwise; Figure 2As can be seen, the secondary pulley 25 is connected to the conveyor belt pulley A 26 via belt drive. Therefore, when viewed from direction A, both the secondary pulley 25 and the conveyor belt pulley A 26 rotate clockwise. Figure 2 The conveyor belt on the right in the view also rotates clockwise, transporting the cut meat slices or strips; there is also a pulley at the other end of the shaft where conveyor belt pulley A26 is located. Figure 1 The conveyor belt pulley B 27 shown is connected to the conveyor belt pulley C 28 via belt drive. Figure 1 From the viewpoint, both pulleys rotate counterclockwise, and the conveyor belt pulley C28 is... Figure 1 The drive wheel of the right-hand conveyor belt, so Figure 1 The conveyor belt on the right side of the view turns counterclockwise, allowing the user to place meat pieces on it. The meat is then transported to the cutting section in the middle via the input conveyor belt, and finally output via the output conveyor belt.
