Description

Technical Field

[0001] The present invention relates to the technical field of food machinery, and more particularly to an electric and manual dual-purpose meat food processing machine. Background Art

[0002] Traditional meat slicing and dicing machines are generally categorized as either inclined or upright blade types. The blades are positioned at a 90-degree angle to the meat carrier. Inclined blades are suitable for cutting slightly frozen ingredients, where the material is fed by gravity, sliding down the inclined meat carrier, supplemented by manual effort. Upright blades are suitable for cutting fresh ingredients, where the slicing process relies entirely on manual feeding. In recent years, upright blade manual slicing machines have emerged. Feeding is achieved manually, driven by a ratchet-pawl mechanism and a lead screw nut driven by the interaction of a fixed roller and a swinging block mounted on a reciprocating meat carrier. These machines have the following drawbacks: 1. When the pawl returns to its original position and slides over the ratchet teeth, the spring force creates a rattling noise, making the work environment noisy and affecting the quality of the product. 2. Due to the limited rotational angle within which the roller can push the swinging block, the automatic feed spacing is small, and stepless speed regulation of slice thickness is not possible. At the same time, both the inclined blade and upright blade slicers use electric drive to rotate the main drive shaft to achieve the operation of the relevant systems. Once the power is cut off, the slicer will not be able to work. Summary of the Invention

[0028] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0029] This embodiment is merely a general description and is not intended to be limiting. The accompanying drawings illustrate only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the spirit of the present invention, devises a similar structure or embodiment without inventiveness, such design shall fall within the scope of protection of the present invention. Example 1

[0030] from Figure 1 、 Figure 2 It can be seen that the present invention is an electric and manual dual-purpose slicer, which includes a base 10, a dual power system, a feeding system, a cutting system, and a swing system; the dual power system includes a main transmission shaft 20, a small spiral bevel gear I21, a manual transmission system, and an electric transmission system. The main transmission shaft 20 and the small spiral bevel gear I21 are both located in the base 10, and the main transmission shaft 20 is arranged on the left and right.

[0031] The dual-purpose slicer of the present invention has two transmission systems, a manual transmission system and an electric transmission system.

The machine is very convenient to use. Different transmission system modes can be selected according to the characteristics of slightly frozen and fresh ingredients. The transmission system drives the feeding system, cutting system, swing system, etc. to achieve food cutting, thereby expanding the scope of application of the machine. The two transmission systems of the present invention do not interfere with each other, making it very convenient to use, and also convenient to operate and maintain. Example 2

[0032] from Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8It can be known that the dual-purpose slicing machine: the manual transmission system comprises a large hand wheel 22 and a clutch assembly 26, and the electric transmission system comprises a motor 23, a worm 24, an empty sleeve worm gear 25 and the clutch assembly 26; the left segment of the main transmission shaft 20 is connected with the large hand wheel 22 through the clutch assembly 26 and is connected with the small spiral bevel gear I 21; the worm 24 and the motor 23 are arranged in front of and behind each other, the motor 23 is arranged at the rear exterior of the pedestal 10, the worm 24 and the empty sleeve worm gear 25 are both arranged in the pedestal 10, the main shaft of the motor 23 is connected with the worm 24, the empty sleeve worm gear 25 is located below the worm 24 and is engaged with the worm 24, and the main transmission shaft 20 is connected with the empty sleeve worm gear 25 through the clutch assembly 26.

[0033] When the large hand wheel 22 is rotated, the main transmission shaft 20 is rotated together through the clutch assembly 26, and at this time, the empty sleeve worm gear 25 is stationary; when the motor 23 is rotated, the worm 24 and the empty sleeve worm gear 25 are rotated, the main transmission shaft 20 is rotated together through the clutch assembly 26, and at this time, the large hand wheel 22 is stationary; the manual transmission system and the electric transmission system complement each other and do not interfere with each other. Example 3

[0034] From Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 It can be known that the dual-purpose slicing machine: the clutch assembly 26 comprises a clutch body I 261 and a plurality of transmission units uniformly distributed, each transmission unit comprises a roller I 262 and a clutch spring I 263; a plurality of L-shaped grooves are uniformly arranged on the outer circle of the clutch body I 261 in the circumferential direction, a blind hole is arranged on the vertical surface of the L-shaped groove, the roller I 262 is arranged on the horizontal surface of the L-shaped groove, one end of the clutch spring I 263 is inserted into the blind hole, and the other end is in contact with the outer circle of the roller I 262; the plurality of arc segments of the clutch body I 261 and the plurality of rollers I 262 form a complete outer circle; in the manual transmission system, the inner hole of the clutch body I 261 is connected with the main transmission shaft 20 through a flat key, the outer circle is matched with the large hand wheel 22 and forms a wedge-shaped space, and the large hand wheel 22 and the clutch assembly 26 form a first one-way overrunning clutch; in the electric transmission system, the inner hole of the clutch body I 261 is connected with the main transmission shaft 20 through a flat key, the outer circle is matched with the empty sleeve worm gear 25 and forms a wedge-shaped space, and the empty sleeve worm gear 25 and the clutch assembly 26 form a second one-way overrunning clutch.

[0035] The first one-way overrunning clutch and the second one-way overrunning clutch both transmit torque in one direction: when the parts (large handwheel 22, idler worm gear 25) that match the outer circle of the clutch body I261 drive the clutch body I261 to rotate along the wedge direction, that is, when the spring I263 is compressed by the wedging action of the roller I262, it drives the main transmission shaft 20 to rotate, otherwise it is idling.

[0036] In order to ensure the normal transmission of the main transmission shaft 20, the direction of the inclined wedge surface of the clutch body Ⅰ261 in the first one-way overrunning clutch and the clutch body Ⅰ261 in the second one-way overrunning clutch is consistent. When any one-way overrunning clutch as the active component rotates clockwise, the other one-way overrunning clutch is in a slipping state: Figure 6 、 Figure 7 As shown, when the large handwheel 22 rotates (clockwise rotation), the main transmission shaft 20 is driven to rotate together through the clutch body Ⅰ261 in the first one-way overrunning clutch. At this time, the idler worm gear 25 is a passive component, and the idler worm gear 25 and the roller Ⅰ262 slip and remain stationary; when the motor 23 drives the worm 24 and the idler worm gear 25 to rotate (clockwise rotation), the main transmission shaft 20 is driven to rotate together through the clutch body Ⅰ261 in the second one-way overrunning clutch. At this time, the large handwheel 22 is a passive component, and the large handwheel 22 and the roller Ⅰ262 slip and remain stationary.

[0037] Therefore, in the present invention, when power is transmitted through the manual transmission system, the electric transmission system does not work; when power is transmitted through the electric transmission system, the manual transmission system does not work, thereby achieving that the manual transmission system and the electric transmission system both complement each other and do not interfere with each other. Example 4

[0038] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 It can be seen that the dual-purpose slicer of the present invention: the swing system includes a large gear shaft 30, a large spiral bevel gear 31, a crank 32, a connecting rod 33, a slider 34, a slider bracket 35, and a meat loading platform assembly 36. The large gear shaft 30 is arranged vertically and perpendicular to the main transmission shaft 20. The large spiral bevel gear 31 is sleeved on the large gear shaft 30 and meshes with the small spiral bevel gear Ⅰ21. The handle end of the crank 32 is sleeved on the large gear shaft 30. One end of the connecting rod 33 is connected to the slider 34 and the other end is connected to the rod end of the crank 32. The slider bracket 35 is connected to the part where the slider 34 extends out of the base 10; the meat loading platform assembly 36 is arranged above the slider bracket 35.

[0039] In the swinging system: the crank 32, the connecting rod 33, and the slider 34 form a crank-connecting rod slider mechanism: when the main shaft 20 drives the small spiral bevel gear I 21 to rotate, the large spiral bevel gear 31 rotates accordingly. Under the action of the crank-connecting rod slider mechanism, the slider 34 drives the slider bracket 35 to swing left and right, causing the meat loading platform assembly 36 to perform a reciprocating meat cutting (left and right) motion.

[0040] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 It can be seen that the dual-purpose slicer of the present invention: the cutting system includes a knife seat 40, a blade 41, a knife shaft assembly 42, a small spiral bevel gear II 43, a rear transmission shaft 44, a large transmission wheel 45, a transmission belt 46, and a small transmission wheel 47. The rear transmission shaft 44 is arranged front and rear and is perpendicular to the main transmission shaft 20 and the large gear shaft 30. The small spiral bevel gear II 43 is sleeved on one end of the rear transmission shaft 44 and meshes with the large spiral bevel gear 31. The large transmission wheel 45 is sleeved on the other end of the rear transmission shaft 44. The knife seat 40 is fixed to the right rear part of the base 10. The knife shaft assembly 42 is arranged in the knife seat 40. The blade 41 is located outside the knife seat 40 and is connected to the knife shaft assembly 42. The transmission belt 46 connects the large transmission wheel 45 and the small transmission wheel 47.

[0041] In the cutting system, when the large spiral bevel gear 31 rotates, it drives the small spiral bevel gear II 43, and the drive belt 46 transmits power upward to the cutter shaft assembly 42, thereby driving the blade 41 to rotate and perform the blade cutting function. The large drive wheel 45, drive belt 46, and small drive wheel 47 can be sprockets, chains, pulleys, or synchronous belts.

[0042] As can be seen from the above, a spiral bevel gear set is arranged at the output end of the main transmission shaft, which is divided into two motion outputs: the small spiral bevel gear I21 on the main transmission shaft 20 is meshed with the large spiral bevel gear 31 installed on the vertical surface, and the large spiral bevel gear 31 is meshed with the small spiral bevel gear II43 arranged backward in the horizontal plane; the large spiral bevel gear 31 is connected downward through the large gear shaft to drive the crank-connecting rod mechanism, and drives the meat carrier assembly to reciprocate through the slider; the small spiral bevel gear II43 transmits power horizontally to the rear transmission shaft and transmits power upward through a chain or synchronous belt to the knife shaft assembly to complete the cutting motion. Example 5

[0043] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10It can be seen that the dual-purpose slicer of the present invention: the feeding system includes a distance adjustment component 50, a friction wheel mechanism 51, and a front-back moving mechanism; the front-back moving mechanism includes a front bracket 521, a rear bracket 522, a concave connecting bracket 523, a swing bracket 524, a trapezoidal screw rod 525, an opening and closing nut 526, an opening and closing torsion spring 527, a swing shaft 528, a moving handle 529, and a slide rod 530; the meat loading platform component 36 includes a fixed table 361 and a movable table 362; the fixed table 361 is fixed on the upper part of the slider bracket 35, and the front bracket 521 and the rear bracket 522 are respectively provided on the front and rear sides of the left side below the fixed table 361. The front end of the trapezoidal screw rod 525 is connected to the front bracket 521, and the rear end passes through the rear bracket 522 and is connected to the friction wheel mechanism 51 to form a third one-way overrunning clutch. The right side below the fixed table 361 A sliding rod 530 is provided; the movable table 362 is arranged on the top of the fixed table 361, the concave connecting bracket 523 is fixed to the inner lower part of the lower extension edge of the left side of the movable table 362, the front and rear baffles of the swinging bracket 524 are located on the front and rear sides of the front and rear baffles of the concave connecting bracket 523, the swing shaft 528 connects the concave connecting bracket 523 and the swinging bracket 524, the opening and closing torsion spring 527 is sleeved on the swing shaft 528 and is located on the middle section between the front and rear baffles of the concave connecting bracket 523, the opening and closing nut 526 is connected to the opening and closing torsion spring 527 and is located below the trapezoidal screw rod 525, the moving handle 529 is connected to the left end of the swinging bracket 524, and the lower extension edge of the right side of the movable table 362 is sleeved on the middle part of the sliding rod 530; the distance adjustment component 50 is arranged on the top of the base 10 and is located on the left side of the meat loading platform component 36.

[0044] When the moving handle 529 is downward and the opening and closing nut 526 is opened, the operator holds the moving handle 529 to quickly move the movable table 362 to the desired position; when the moving handle 529 is upward, the opening and closing nut 526 and the trapezoidal screw 525 are closed: when the meat loading platform assembly 36 is located at the rightmost side, the blade 41 starts cutting, and during the cutting process, the meat loading platform assembly 36 moves to the left. When the meat loading platform assembly 36 reciprocates and returns to a certain distance before the left end, the friction wheel assembly 51 contacts the distance adjustment assembly 50 to make the friction wheel roll, driving the trapezoidal screw 525 to rotate, causing the movable table 362 and related components thereon to move backward, completing the feeding movement; when the meat loading platform assembly 36 moves to the left to the extreme position and then moves to the right, due to the presence of the one-way overrunning clutch, although the friction wheel rotates in the opposite direction, the trapezoidal screw 525 does not rotate, and the movable table 362 no longer moves back and forth. Therefore, through the reciprocating motion of the meat carrier assembly 36 and the feeding motion, the blade 41 cuts all the meat slices.

[0045] During the forward and backward movement of the movable platform 362 , the slide bar 530 plays a guiding role. Example 6

[0046] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 、 Figure 13 It can be seen that the dual-purpose slicer of the present invention: the friction wheel mechanism 51 includes a friction wheel 511, a clutch body II 512, and a plurality of evenly distributed compression units, each compression unit includes a roller II 513 and a clutch spring II 514; the outer circle of the clutch body II 512 is evenly distributed along the circumferential direction with a plurality of L-shaped grooves, the vertical surface of the L-shaped groove is provided with a blind hole, the roller II 513 is provided on the horizontal surface of the L-shaped groove, one end of the clutch spring II 514 extends into the blind hole, and the other end contacts the outer circle of the roller II 513; the multiple arc surfaces of the clutch body II 512 and the multiple rollers II 513 form a complete outer circle; the inner hole of the clutch body II 512 is connected to the outer circle segment of the trapezoidal screw 525 through a flat key, and its outer circle cooperates with the friction wheel 511, and the friction wheel 511 and the clutch body unit and the trapezoidal screw 525 form a third one-way overrunning clutch.

[0047] The friction wheel assembly 51 and the trapezoidal screw 525 utilize a one-way transmission mechanism. During the meat carrier assembly 36's return stroke, i.e., leftward movement, the friction wheel 511 contacts the adjustable spacing assembly 50, causing it to roll and rotate. This rotation drives the trapezoidal screw 525, causing the movable platen 362 to move back and forth during the second half of the return stroke, completing the feeding process. When the meat carrier assembly 36 completes its return stroke and moves rightward, the friction wheel 511 also contacts the adjustable spacing assembly 50 and rolls, but the trapezoidal screw 525 does not rotate, and the movable platen 362 does not move. Example 7

[0048] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 It can be seen that the dual-purpose slicer of the present invention: the distance adjustment component 50 includes a base 501, a rack plate 502, a distance adjustment gear shaft 503, and a distance adjustment knob 504. The base 501 is fixed on the top of the base 10, the distance adjustment gear shaft 503 is arranged in the base 501 and is connected to the distance adjustment knob 504 outside the base 501, and the front and rear ends of the rack plate 502 are embedded in the groove of the base 501 and the bottom thereof is engaged with the distance adjustment gear shaft 503.

[0049] In the pitch adjustment assembly: the pitch adjustment gear shaft 503 is rotated by rotating the pitch adjustment knob 504 , which drives the rack plate 502 to move left and right to the required position and then locks the pitch adjustment knob 504 .

[0050] When the meat carrier assembly 36 reaches a certain distance before its left end during its reciprocating motion, the friction wheel 511 contacts the surface of the rack plate 502, thereby rotating the trapezoidal lead screw 525. Because the linkage mechanism determines the distance of the meat carrier assembly 36's leftward motion, adjusting the left and right positions of the rack plate 502 controls the contact distance between the friction wheel 511 and the rack plate 502, thereby varying the effective number of rotations of the friction wheel 511 and, in turn, the forward and backward movement of the movable platen 362 to meet varying slice thickness requirements. Furthermore, the friction wheel's rolling feed mechanism eliminates any restrictions on the angle of rotation, expanding the range of slice thickness adjustment and enabling stepless speed regulation. Furthermore, the friction wheel 511 rolls virtually silently on the rack plate 502, eliminating the loud rattling noise associated with the return stroke of the ratchet and pawl mechanism. This provides a quiet working environment and enhances the product's quality. Example 8

[0051] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 It can be seen that the dual-purpose slicer of the present invention: the forward and backward moving mechanism also includes a rolling shaft 531 and a roller 532; a rolling shaft 531 is provided on the upper part of the lower extension edge of the left side of the movable table 362, and the roller 532 is provided on the rolling shaft 531 and contacts the L-shaped side wing of the fixed table 361.

[0052] When the movable platform 362 moves forward and backward, the rollers 532 roll on the L-shaped side wings of the fixed platform 361, further improving the stability of the movement.

[0053] The present invention uses a base 10 and a tool holder 40 as the body for carrying various components, and a dual power system, an internal and external feeding system, a cutting system, a swinging system, etc. are installed inside: the motor 23, the worm 24, and the idler worm gear 25 are used as the input power for the electric drive components; the large handwheel assembly 22 is used as the input power for the human drive components. Both powers can independently drive the main transmission shaft 20 arranged on the left and right. A spiral bevel gear set is arranged at the output end of the main transmission shaft, which is divided into two motion outputs. The power is transmitted laterally and upward in the horizontal plane to form the cutting of the blade, and the crank-connecting rod mechanism is connected and driven in the vertical plane to form the reciprocating motion of the meat carrier assembly 36; the friction wheel assembly, the front and rear moving mechanism, and the distance adjustment assembly are combined to realize the feeding motion of the meat carrier assembly 36.
