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

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

[0040] By adopting the above scheme, when the height at which the frozen meat is placed on the chain conveyor 1 is lowered, the height of the part of the fixed assembly 5 that contacts the frozen meat will also change. Synchronously, the height of the transmission assembly 6 will also change with the fixed assembly 5, thereby causing the gear member 45 to rotate and drive the worm gear 43 to rotate, and the worm gear 43 will drive the cam shaft 2 431 to slide in the guide groove 42, and cooperate with the circumferential limitation of the adjusting cylinder 41 by the limit block 1 331 being stuck in the limit groove 412 and the horizontal limitation of the worm gear 43 by the limit block 2 332, so that the funnel-shaped inner wall of the adjusting cylinder 41 will squeeze the round shaft rod 37, and through the limitation of the spring combination rod 351, the round shaft rod 37 will drive the connecting rod 36 closer to the axis of the transmission shaft 34, and at the same time, the overall reciprocating stroke of the cutting assembly 2 is reduced, thereby solving the problem of low cutting efficiency of frozen meat cutting or excessive tool wear caused by excessive reciprocating stroke of the tool.

[0043] By adopting the above scheme, when the frozen meat is transported on the chain conveyor 1, it will first 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 is lowered, the pressing block 53 and the crawler 54 will move downward and maintain contact with the frozen meat under the support of the limit of the spring combination rod 4 55 and the spring part.

[0044] like Figure 3 , Figure 4 , Fig. 9 and Fig.10 As shown, the slicing knife 25 is also provided with anti-blocking components 7 for cleaning the accumulated meat blocks on the slicing knife 25 at equal intervals; the anti-blocking component 7 includes an inclined plate 71 fixed to the slicing knife 25, a top rod 72 is hinged on the connecting plate 23, the bottom end of the top rod 72 extends to the inside of the inclined plate 71, and a straight groove 73 is formed on the top of the top rod 72;

[0045] The bottom of the top plate 22 is fixedly connected with fixed blocks 221 at equal distances. The bottom end of the fixed block 221 has a convex shaft 222 that can slide in the straight groove 73.

[0046] By adopting the above scheme, the cutting knife 25 will first contact the frozen meat and keep the relative height unchanged by the downward movement of the cutting assembly 2 as a whole, and then the spring combination rod 1 21 will drive the spring combination rod 24 to drive the connecting plate 23 downward, and make the spring part of the spring combination rod 24 be compressed. At this time, the top plate 22 will drive the fixed block 221 and the convex shaft 1 222 downward, so that the convex shaft 1 222 slides in the straight groove 73 and the push rod 72 is retracted into the inclined plate 71, and then the cutting assembly 2 as a whole can continue to move downward to cut the frozen meat. When the cutting assembly 2 is reset upward, the spring combination rod 1 21 will drive the top plate 22 and the spring combination rod 24 upward, and the upward movement of the top plate 22 will make the fixed block 221 drive the convex shaft 1 222 upward in the straight groove 73, so that the push rod 72 pops open and the frozen meat in the groove part of the cutting knife 25 is ejected to avoid accumulation.

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

[0048] First, when the frozen meat is transported on the chain conveyor 1, it will first 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 is reduced, the pressing block 53 and the crawler 54 will move downward and maintain contact with the frozen meat under the support of the limit of the spring combination rod 4 55 and the spring part. At the same time, the height change of the pressing block 53 will also drive the sleeve rod 52 to move outside the rod 1 51 and cause the rod 1 51 to rotate around the axis;

[0049] The running motor 31 drives the transmission plate 35 to rotate through the gear box 32 and the transmission shaft 34, and the transmission plate 35 drives the bottom end of the connecting rod 36 to rotate around the axis through the round shaft rod 37. At this time, the connecting rod 36 drives the cutting assembly 2 to reciprocate to cut the frozen meat into pieces. When the height of the frozen meat placed on the chain conveyor 1 is reduced, the height of the slider 511 will also be reduced and the upward support for the cross bar 1 62 will be lost. The spring combination rod 5 61 will also drive the cross bar 2 63 and the tooth plate 64 downward under its own elastic force, so that the gear member 45 The worm wheel 43 rotates and drives the worm wheel 43 to rotate, and the worm wheel 43 drives the convex shaft 2 431 to slide in the guide groove 42, and cooperates with the circumferential limitation of the adjusting cylinder 41 by the limiting block 1 331 being stuck in the limiting groove 412 and the horizontal limitation of the worm wheel 43 by the limiting block 2 332, so that the funnel-shaped inner wall of the adjusting cylinder 41 squeezes the round shaft rod 37, and through the limitation of the spring combination rod 351, the round shaft rod 37 drives the connecting rod 36 closer to the axis of the transmission shaft 34, and at the same time reduces the overall reciprocating stroke of the cutting block assembly 2;

[0050] When the cutting assembly 2 as a whole descends, first the cutting knife 25 will contact the frozen meat and keep the relative height unchanged, then the spring combination rod 1 21 will drive the spring combination rod 24 to drive the connecting plate 23 downward, and make the spring part of the spring combination rod 24 compressed, at this time the top plate 22 will drive the fixing block 221 and the convex shaft 1 222 downward, so that the convex shaft 1 222 slides in the straight groove 73, and the push rod 72 is retracted into the inclined plate 71, and then the cutting assembly 2 as a whole can continue to descend to cut the frozen meat, when the cutting assembly 2 is reset upward, the spring combination rod 1 21 will drive the top plate 22 and the spring combination rod 24 upward, and the upward movement of the top plate 22 will make the fixing block 221 drive the convex shaft 1 222 upward in the straight groove 73, so that the push rod 72 pops open and the frozen meat in the groove part of the cutting knife 25 is ejected to avoid accumulation.
