Description

Technical Field

[0001] The invention belongs to the technical field of food processing, in particular to a slicing device for processing prefabricated dishes. Background Art

[0002] In the process of preparing meals, some frozen meat is used as the core ingredient, which is usually cut into blocks before processing. Operators usually place the frozen meat on a conveyor plate and use a reciprocating mechanism to drive a specially shaped cutting knife to cut it into blocks.

[0003] Since meat is usually frozen during transportation, and the height of each part of it is uneven when placed on the conveyor chain, operators usually increase the reciprocating stroke of the reciprocating mechanism to adapt to this change. At this time, the originally compact and efficient cutting process becomes tedious and lengthy due to the increased stroke, which reduces the number of back and forth movements of the cutting knife per unit time, thereby increasing the time required to cut each piece of frozen meat.

[0004] If the reciprocating frequency is increased, the impact force between the cutting knife and the frozen meat will increase dramatically. Since the frozen meat is hard, the cutting knife is very likely to be damaged by chipping and curling under high-frequency impact, which will shorten the service life of the tool and reduce the overall production efficiency. Therefore, in order to solve the above problems, a cutting device for pre-prepared dish processing is proposed. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a slicing device for processing pre-made dishes, which solves the problems of low cutting efficiency of frozen meat slicing or excessively fast tool wear.

A convex shaft two that can slide in the guiding groove is fixedly connected to the inner ring of the worm gear. A worm that meshes with the worm gear is movably connected to the support. A gear member that meshes with the bottom of the transmission component is fixedly sleeved on the worm. A limiting block one that can slide in the limiting groove is fixedly connected to the support. A limiting block two for axially limiting the worm gear is also fixedly connected to the support. A tension spring is also sleeved outside the transmission shaft, and the two ends of the tension spring are fixedly connected to the adjusting cylinder and the support respectively;

[0009] The inner wall of one end of the adjusting cylinder is funnel-shaped, and one end of the round shaft rod abuts against the inclined surface of the funnel-shaped inner wall of the adjusting cylinder.

[0010] Preferably, the cutting block component includes a spring combination rod one elastically connected to both sides of the bracket. A top plate is fixedly connected to the top of the spring combination rod one. A plurality of spring combination rods two are fixedly connected to the top plate. The bottom end of the spring combination rod two extends below the top plate and is movably sleeved with a connecting plate. The spring part of the connecting plate is used to support the separation of the connecting plate and the top plate. A cutting knife is fixedly connected to the bottom of the connecting plate.

[0011] Preferably, the bottom of one of the spring combination rods one is hinged to the top end of the connecting rod.

[0012] Preferably, a horizontal shaft is fixedly connected to the bracket;

[0013] The fixing component includes a rod one hinged to the horizontal shaft. A sleeve rod is movably sleeved at one end of the rod one. A pressing block is hinged to one end of the sleeve rod. A crawler is arranged at the bottom of the pressing block. A spring combination rod four is also fixedly connected to the pressing block. The rod part of the spring combination rod four penetrates through the bracket upwards and extends above it. The spring part of the spring combination rod four is fixedly connected to the bracket to support the pressing block to maintain a downward trend.

[0014] Preferably, a gap is left between the crawler and the cutting knife.

[0015] Preferably, a slider is movably sleeved on the first rod; the transmission assembly includes a fifth spring combined rod elastically sleeved on the bracket, and the fifth spring combined rod has a downward trend under its own elastic force. The top end of the fifth spring combined rod is fixedly connected with a first cross bar that can slide in the slider. The bottom end of the fifth spring combined rod is fixedly connected with a second cross bar, and the bottom end of the second cross bar is fixedly connected with a toothed plate that meshes with the gear part.

[0016] Preferably, the cutting knife is also equidistantly provided with an anti-blocking assembly for cleaning the accumulated meat blocks on the cutting knife.

[0017] Preferably, the anti-blocking assembly includes an inclined plate fixedly connected to the cutting knife. A top rod is hinged on the connecting plate, and the bottom end of the top rod extends into the inclined plate. A straight groove is formed at the top of the top rod;

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] When the height of the frozen meat placed on the chain conveyor is reduced in the above solution, at this time, the height of the slider will also decrease and lose the upward support for the first cross bar. Under the action of its own elastic force, the fifth spring combined rod will drive the second cross bar and the toothed plate to move downward, so that the gear part rotates and drives the worm to rotate. The worm will drive the second convex shaft to slide in the guiding groove, and cooperate with the circumferential limit of the adjusting cylinder by the first limiting block being inserted into the limiting groove and the horizontal limit of the worm by the second limiting block, so that the funnel-shaped inner wall of the adjusting cylinder will squeeze the round shaft rod, and through the limit of the third spring combined rod, the round shaft rod will drive the connecting rod closer to the axis of the transmission shaft, and at the same time, the overall reciprocating stroke of the cutting assembly is also reduced, thus solving the problem that the cutting efficiency of frozen meat is low or the tool wears out too fast due to the too large reciprocating stroke of the tool;

[0021] When the cutting assembly moves downward as a whole in the above solution, the cutting knife first contacts the frozen meat and keeps the relative height unchanged. Subsequently, the first spring combined rod will drive the second spring combined rod to drive the connecting plate to move downward, and the spring part of the second spring combined rod will be compressed. At this time, the top plate will drive the fixing blocks and the first convex shafts to move downward, so that the first convex shafts slide in the straight grooves, and the top rods retract into the inclined plates. Subsequently, the cutting assembly can continue to move downward to cut the frozen meat. When the cutting assembly moves upward and resets, the first spring combined rod will drive the top plate and the second spring combined rod to move upward, and the upward movement of the top plate will cause the fixing blocks to drive the first convex shafts to move upward in the straight grooves, so that the top rods bounce open and eject the frozen meat in the groove part of the cutting knife to avoid accumulation.

A bracket 11 and a cutting assembly 2 are installed on the chain conveyor 1. A driving assembly 3 for driving the cutting assembly 2 to reciprocate up and down is installed at the bottom of the chain conveyor 1. It further includes: an adjusting assembly 4, which is arranged on the driving assembly 3 and is used to adjust the distance of the driving assembly 3 driving the cutting assembly 2 in the vertical direction; a fixing assembly 5, which is installed on the bracket 11 and is used to press and fix the frozen meat conveyed on the chain conveyor 1; a transmission assembly 6, which is arranged on the bracket 11 and adjusts the adjusting assembly 4 following the movement of the fixing assembly 5;

[0035] The driving assembly 3 includes a motor 31, a gearbox 32 and a support 33 fixedly installed at the bottom of the bracket 11. A transmission shaft 34 is connected to the support 33 through a bearing. One end of the transmission shaft 34 is fixedly connected with a transmission disc 35. The transmission shaft 34 is in transmission connection with the output shaft of the motor 31 through the gearbox 32. A spring combination rod three 351 is fixedly connected inside the transmission disc 35. A round shaft rod 37 is sleeved outside the spring combination rod three 351. The round shaft rod 37 is pushed outwards by the elastic force of the spring part of the spring combination rod three 351. A connecting rod 36 is connected to the outside of the round shaft rod 37 through a bearing. The top end of the connecting rod 36 is in transmission connection with the cutting assembly 2;

[0036] The adjusting assembly 4 includes an adjusting cylinder 41 movably sleeved outside the transmission shaft 34. A guiding groove 42 and a limiting groove 412 are formed on the outer periphery of the adjusting cylinder 41. A worm gear 43 is movably sleeved on the outer periphery of the adjusting cylinder 41. A convex shaft two 431 that can slide in the guiding groove 42 is fixedly connected to the inner ring of the worm gear 43. A worm 44 meshing with the worm gear 43 is movably connected to the support 33. A gear member 45 meshing with the bottom of the transmission assembly 6 is fixedly sleeved on the worm 44. A limiting block one 331 that can slide in the limiting groove 412 is fixedly connected to the support 33. A limiting block two 332 for axially limiting the worm gear 43 is also fixedly connected to the support 33. A tension spring 411 is also sleeved outside the transmission shaft 34. Two ends of the tension spring 411 are respectively fixedly connected with the adjusting cylinder 41 and the support 33;

[0037] The inner wall of one end of the adjusting cylinder 41 is in a funnel shape. One end of the round shaft rod 37 abuts against the inclined surface of the funnel-shaped inner wall of the adjusting cylinder 41;

[0038] The cutting block assembly 2 includes a first combined spring rod 21 elastically connected to both sides of the bracket 11. A top plate 22 is fixedly connected to the top of the first combined spring rod 21. A plurality of second combined spring rods 24 are fixedly connected to the top plate 22. The bottom end of the second combined spring rod 24 extends below the top plate 22 and is movably sleeved with a connecting plate 23. The spring part of the connecting plate 23 is used to support the separation of the connecting plate 23 and the top plate 22. A cutting knife 25 is fixedly connected to the bottom of the connecting plate 23;

[0039] The bottom of one of the first combined spring rods 21 is hinged to the top end of the connecting rod 36;

[0040] With the above solution, when the height of the frozen meat placed on the chain conveyor 1 is reduced, the height of the part of the fixing component 5 in contact with the frozen meat will also change. Synchronously, the height of the transmission component 6 will also change with the fixing component 5, so that the gear part 45 rotates and drives the worm wheel 43 to rotate. The worm wheel 43 drives the second convex shaft 431 to slide in the guiding groove 42, and cooperates with the circumferential limit of the adjusting cylinder 41 by the first limiting block 331 being inserted into the limiting groove 412 and the horizontal limit of the worm wheel 43 by the second limiting block 332. Thus, the funnel-shaped inner wall of the adjusting cylinder 41 presses against the round shaft rod 37, and through the limit of the third combined spring rod 351, the round shaft rod 37 drives the connecting rod 36 closer to the axis of the transmission shaft 34. At the same time, the overall reciprocating stroke of the cutting block assembly 2 is also reduced, thus solving the problem of low cutting efficiency of frozen meat or excessive tool wear caused by too large a reciprocating stroke of the tool.

[0041] As Figure 1 、 Figure 2 、 Figures 7 - 9 As shown in the figure, a horizontal shaft 111 is fixedly connected to the bracket 11. The fixing component 5 includes a first rod 51 hinged to the horizontal shaft 111. One end of the first rod 51 is movably sleeved with a sleeve rod 52. One end of the sleeve rod 52 is hinged to a pressing block 53. A crawler 54 is arranged at the bottom of the pressing block 53. A fourth combined spring rod 55 is also fixedly connected to the pressing block 53. The rod part of the fourth combined spring rod 55 penetrates through the bracket 11 upward and extends above it. The spring part of the fourth combined spring rod 55 is fixedly connected to the bracket 11 to support the pressing block 53 to maintain a downward trend. A gap is left between the crawler 54 and the cutting knife 25;

[0042] A slider 511 is movably sleeved on the first rod 51. The transmission component 6 includes a fifth combined spring rod 61 elastically sleeved on the bracket 11, and the fifth combined spring rod 61 has a downward trend under its own elastic force. A first cross bar 62 that can slide in the slider 511 is fixedly connected to the top end of the fifth combined spring rod 61. A second cross bar 63 is fixedly connected to the bottom of the fifth combined spring rod 61. A tooth plate 64 meshing with the gear part 45 is fixedly connected to the bottom of the second cross bar 63;

[0043] With the above solution, when the frozen meat is conveyed on the chain conveyor 1, it will first come into contact with the crawler 54. At this time, the change in the contact height between the crawler 54 and the frozen meat will cause the pressing block 53 to move up or down. When the height of the frozen meat decreases, the pressing block 53 and the crawler 54 will move down under the limitation of the spring combination rod four 55 and the support of the spring part to maintain contact with the frozen meat.

[0044] As Figure 3 , Figure 4 , Figure 9 and Figure 10 shown, anti-blocking components 7 for cleaning the meat blocks accumulated on the cutting knife 25 are also equidistantly arranged on the cutting knife 25; the anti-blocking components 7 include a sloping plate 71 fixedly connected to the cutting knife 25, a top rod 72 is hinged on the connecting plate 23, the bottom end of the top rod 72 extends into the sloping plate 71, and a straight groove 73 is formed at the top of the top rod 72;

[0045] Fixing blocks 221 are equidistantly and fixedly connected to the bottom of the top plate 22, and a first convex shaft 222 capable of sliding in the straight groove 73 is fixedly provided at the bottom end of the fixing block 221;

[0046] With the above solution, when the cutting component 2 moves downward as a whole, the cutting knife 25 will first come into contact with the frozen meat and maintain a constant relative height. Subsequently, the spring combination rod one 21 will drive the spring combination rod two 24 to drive the connecting plate 23 downward, and the spring part of the spring combination rod two 24 will be compressed. At this time, the top plate 22 will drive the fixing block 221 and the first convex shaft 222 downward, so that the first convex shaft 222 slides in the straight groove 73, and the top rod 72 is retracted into the sloping plate 71. Subsequently, the cutting component 2 can continue to move downward to cut the frozen meat. When the cutting component 2 moves upward and resets, the spring combination rod one 21 will drive the top plate 22 and the spring combination rod two 24 upward, and the upward movement of the top plate 22 will cause the fixing block 221 to drive the first convex shaft 222 to move upward in the straight groove 73, so that the top rod 72 pops open and ejects the frozen meat in the groove part of the cutting knife 25 to avoid accumulation.

[0047] The working principle and usage process of the present invention:

[0048] First, when the frozen meat is conveyed on the chain conveyor 1, it will first come into contact with the crawler 54. At this time, the change in the contact height between the crawler 54 and the frozen meat will cause the pressing block 53 to move up or down. When the height of the frozen meat decreases, the pressing block 53 and the crawler 54 will move down under the limitation of the spring combination rod four 55 and the support of the spring part to maintain contact with the frozen meat. At the same time, the change in the height of the pressing block 53 will also drive the sleeve rod 52 to move outside the rod one 51 and cause the rod one 51 to rotate around the axis;

[0049] The running motor 31 drives the rotating disc 35 to rotate through the gearbox 32 and the transmission shaft 34, and the rotating disc 35 drives the bottom end of the connecting rod 36 to rotate around the shaft through the round shaft rod 37. At this time, the connecting rod 36 drives the cutting block assembly 2 to reciprocate to cut the frozen meat. When the height of the frozen meat placed on the chain conveyor 1 decreases, the height of the slider 511 also decreases and loses the upward support for the first cross bar 62. The fifth spring combination rod 61 drives the second cross bar 63 and the toothed plate 64 to move downward under the action of its own elastic force, so that the gear member 45 rotates and drives the worm wheel 43 to rotate. The worm wheel 43 drives the second convex shaft 431 to slide in the guide groove 42, and cooperates with the circumferential limit of the adjusting cylinder 41 by the first limiting block 331 being stuck into the limiting groove 412 and the horizontal limit of the worm wheel 43 by the second limiting block 332, so that the funnel-shaped inner wall of the adjusting cylinder 41 squeezes the round shaft rod 37, and through the limit of the third spring combination rod 351, the round shaft rod 37 drives the connecting rod 36 to be closer to the axis of the transmission shaft 34, and at the same time, the overall reciprocating stroke of the cutting block assembly 2 is also reduced;

[0050] When the whole cutting block assembly 2 moves downward, first the cutting knife 25 will come into contact with the frozen meat first and keep the relative height unchanged. Then the first spring combination rod 21 drives the second spring combination rod 24 to drive the connecting plate 23 to move downward, and the spring part of the second spring combination rod 24 is compressed. At this time, the top plate 22 drives the fixed block 221 and the first convex shaft 222 to move downward, so that the first convex shaft 222 slides in the straight groove 73, and the ejector rod 72 retracts into the inclined plate 71. Then the whole cutting block assembly 2 can continue to move downward to cut the frozen meat. When the cutting block assembly 2 moves upward and resets, the first spring combination rod 21 drives the top plate 22 and the second spring combination rod 24 to move upward, and the upward movement of the top plate 22 causes the fixed block 221 to drive the first convex shaft 222 to move upward in the straight groove 73, so that the ejector rod 72 pops out and ejects the frozen meat in the groove part of the cutting knife 25 to avoid accumulation.
