Description

Technical Field

[0001] This invention relates to the field of meat processing equipment, and more specifically to a cutting machine for meat containing tendons. Background Technology

[0002] Currently, the double-roller disc cutter cutting device is widely used in meat slicing. It cuts food by meshing two sets of relatively rotating disc cutter rollers. It has the characteristics of simple structure and high efficiency of continuous operation, and is widely used in ordinary meat slicing.

[0003] However, in actual production, this structure has obvious technical defects: when cutting chicken gizzards, chicken livers, and meats containing tough fascia, it is difficult to completely cut the fascia. Because the roller disc cutter uses an interlocking extrusion cutting method, there are gaps between the blades. The tough fascia is easily squeezed and pulled into the gaps, causing it to be stretched and avoidance, making it impossible to form effective shearing. This leads to problems such as blade sticking and adhesion, which not only affects the output qualification rate but also easily causes discharge blockage, failing to meet the stable processing requirements of high-toughness ingredients. Summary of the Invention

[0004] The present invention aims to provide a cutting machine for meat containing fascia, so as to solve the problem that it is difficult to completely cut the fascia when cutting meat containing fascia in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cutting machine for meat containing tendons and fascia includes a machine body with two rotating cutter rollers arranged in parallel inside the machine body. Several disc cutters are evenly installed on the cutter rollers along their axial direction. The disc cutters on the two cutter rollers mesh with each other. The area above the meshing area of ​​the two cutter rollers is a feeding area and the area below is a dropping area. Fixed blade combs are provided on both sides of the dropping area, and the blades of the fixed blade combs are inserted into the gaps between the disc cutters one by one.

[0006] Preferably, as an improvement, a combing mechanism is slidably provided on the outer side of the fixed comb.

[0007] Preferably, as an improvement, the combing mechanism includes a combing plate, on which a plurality of combing teeth are evenly arranged, each combing tooth being inserted into the gap between the teeth of the fixed comb, and the combing plate is connected to a drive mechanism for driving its reciprocating motion.

[0008] Preferably, as an improvement, the drive mechanism includes an arc-shaped guide rail concentrically arranged with the cutter roller, a slider slidably connected to the guide rail, a spring connecting the slider and the guide rail, an arc-shaped guide plate on one side of the guide rail, a drive wheel and a driven wheel rotatably arranged at both ends of the guide plate, a synchronous belt tensioned between the drive wheel and the driven wheel, the guide plate supporting the synchronous belt, the synchronous belt being fixedly connected to the slider, and a drive component connected to the drive wheel for driving its forward and reverse rotation.

[0009] Preferably, as an improvement, the drive component includes an incomplete gear coaxially connected to one of the cutter rollers, the incomplete gear meshing with a complete gear, and the complete gear coaxially connected to the drive wheel.

[0010] Preferably, as an improvement, the diameter of the incomplete gear is smaller than the diameter of the complete gear.

[0011] The principles and beneficial effects of this solution are as follows: 1. Meat is fed into the feeding area and initially sheared by the disc blades on two cutting rollers in the meshing area. For any tough fascia that is not completely cut, a secondary cut is achieved by the rotational force of the cutting rollers and the fixed blade combs on both sides of the feeding area as the meat falls. This solution, through two-stage cutting, can effectively and stably cut meat containing fascia, fundamentally solving the technical problem of traditional dual-roller disc blades being unable to cut fascia. At the same time, the fixed blade combs on both sides of the feeding area only make supplementary cuts on the uncut fascia without changing the overall shape of the meat, maximizing the integrity and regularity of the meat slices and avoiding problems such as fragmentation and deformation caused by multiple cuts. In addition, this solution does not require modification to the original double-cutter roller main structure; the technology can be upgraded simply by adding fixed blade combs, which has the advantages of simple structure, convenient modification, and strong practicality.

[0012] 2. This design incorporates a sliding combing mechanism on the outside of the fixed-blade comb, which effectively unblocks food within the comb, preventing it from getting stuck. In practical application, the drive unit intermittently rotates the active wheel in one direction, causing the synchronous belt to rotate in the same direction. The synchronous belt pulls the slider upwards along the arc-shaped guide rail, stretching the spring. This causes the combing teeth to pull a portion of the food outwards from the blades of the fixed-blade comb. When the drive unit stops rotating the active wheel, the spring pulls the slider back to its original position quickly. This rapid return of the combing teeth pushes the food out of the gaps between the blades, effectively unblocking the food and preventing it from getting stuck.

[0013] 3. When the blade roller rotates, it drives the incomplete gear to rotate. The incomplete gear intermittently drives the complete gear to rotate, which in turn drives the drive wheel to rotate intermittently in one direction. When the drive wheel rotates, it pulls the slider upward. After the drive wheel separates from the incomplete gear, the spring pulls the slider downward quickly to reset, clearing the food blockage. This method utilizes the power of the blade roller's rotation to drive the drive wheel, eliminating the need for an additional power source and saving energy resources.

[0014] 4. The diameter of the incomplete gear is smaller than that of the complete gear. This gear set structure can reduce the speed of the drive wheel, making it rotate relatively slowly. This, in turn, makes the slider move relatively slowly. It does not need to rotate synchronously with the cutter roller. The slider can be released only after the cutter roller has rotated for several revolutions. During the rotation of the cutter roller, it can slowly accumulate power. Compared with the method of rotating quickly and synchronously with the cutter roller, it can effectively reduce the wear of components such as the slider and timing belt, and extend their service life.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the embodiments.

[0021] Example A cutting machine for meats containing tendons, such as Figure 1 As shown, the device includes a body 1, within which two cutter rollers 2 are rotatably mounted. The two ends of the cutter rollers 2 are rotatably connected to the body 1 via bearings. A motor is mounted on the body 1, and the output of the motor is connected to a reducer. The output of the reducer is fixedly connected to one end of each cutter roller 2 to drive its rotation. Each cutter roller 2 can be equipped with its own motor and reducer, or they can be driven together by the same motor and reducer via a transmission belt, transmission wheel, or other structure. Specific structures, installation methods, and transmission methods are described in existing technology and will not be elaborated upon here.

[0022] Combination Figure 2 As shown, two cutting rollers 2 are arranged in parallel. Several disc blades 3 are evenly fixedly installed on the cutting rollers 2 along their axial direction. Specifically, the disc blades 3 are connected to the cutting rollers 2 via flat keys to transmit torque. Spacers are fitted between adjacent disc blades 3 to control the blade spacing. The disc blades 3 are sequentially fitted onto the cutting rollers 2 and axially locked and fixed by axial nuts or locking structures, thus achieving the installation of the disc blades 3. They can also be disassembled and replaced according to slicing requirements. The disc blades 3 on the two cutting rollers 2 mesh with each other. The meshing area of ​​the two cutting rollers 2 is the meat cutting area. Above the meshing area is the feeding area 4, and below it is the dropping area 5.

[0023] Arc-shaped fixed-blade combs 6 are installed on both sides of the material feeding area 5. The blades 7 of the two fixed-blade combs 6 are inserted one-to-one into the gaps between the disc blades 3 of the two blade rollers 2. A combing mechanism is slidably arranged on the outer side of the fixed-blade combs 6, combined with... Figure 3 As shown, the combing mechanism includes a slidingly arranged arc-shaped combing plate 16. A plurality of combing teeth 15 are evenly fixed on the combing plate 16, and each combing tooth 15 is inserted into the gap of the blade teeth 7 of the fixed-blade comb 6. The combing plate 16 is arranged on the outer side of the fixed-blade comb 6 along its arc direction, allowing it to slide in the arc direction of the fixed-blade comb 6, thus enabling the combing teeth 15 to slide within the gaps of the blade teeth 7 of the fixed-blade comb 6 when the combing plate 16 slides. The combing plate 16 is connected to a drive mechanism for reciprocating its sliding motion. The drive mechanism includes an arc-shaped guide rail 12 concentrically arranged with the blade roller 2. A slider 13 is slidably connected to the guide rail 12, and the slider 13 is fixed to the bottom of the fixed-blade comb 6. A limiting part 11 is integrally formed at the end of the guide rail 12. A spring 10 is connected between the slider 13 and the limiting part 11, with both ends of the spring 10 fixed to the end face of the slider 13 and the limiting part 11, respectively.

[0024] An arc-shaped guide plate is fixed to the outer circumference of the guide rail 12. A driving wheel 14 and a driven wheel 8 are rotatably mounted at both ends of the guide plate. A synchronous belt 9 is tensioned between the driving wheel 14 and the driven wheel 8. The guide plate supports the synchronous belt 9. The synchronous belt 9 is located on the back side of the slider 13 (the back side in the axial direction). Figure 2 On the back side of the synchronous belt 9, the side is fixedly connected to the slider 13 by screws or other fasteners. The drive pulley 14 is connected to a drive mechanism for driving its forward and reverse rotation. Figure 4 As shown, the driving component includes an incomplete gear 17 coaxially connected to one of the cutter rollers 2, the incomplete gear 17 meshing with a complete gear 18, and the complete gear 18 coaxially connected to the drive wheel 14. In this embodiment, the diameter of the incomplete gear 17 is smaller than the diameter of the complete gear 18.

[0025] Working principle: The meat to be cut is placed into the feeding area 4, and the two cutting rollers 2 rotate in opposite directions. The meat is cut by the disc blades 3 on the two cutting rollers 2 in the meshing area, thus achieving the initial cutting.

[0026] If any fascia remains uncut, it falls from the meshing area to the discharge area 5 along with the cut food. As the cutting roller 2 rotates and moves outward from the discharge area 5, the fascia is carried by the rotation of the cutting roller 2 to the teeth 7 of the fixed-blade combs 6 on both sides of the discharge area 5. The fixed-blade combs 6 then perform a secondary cut, severing the fascia. The severed fascia then falls back into the discharge area 5 and mixes with the other food ingredients before being discharged.

[0027] When the cutter roller 2 rotates, it also drives the incomplete gear 17 connected to it on the same axis to rotate. The incomplete gear 17 intermittently meshes with the complete gear 18. When the incomplete gear 17 meshes with the complete gear 18, the complete gear 18 drives the drive wheel 14 connected to it on the same axis to rotate in the forward direction. When the incomplete gear 17 separates from the complete gear 18, the drive wheel 14 can no longer rotate in the forward direction. When the drive wheel 14 rotates in the forward direction, it drives the synchronous belt 9 and the driven wheel 8 to rotate, causing the slider 13, which is fixed to the synchronous belt 9, to slide up along the arc-shaped guide rail 12 (i.e., slide towards the outside of the material drop area 5). At this time, the spring 10 is stretched, and the comb plate 16, which is fixed to the slider 13, slides outward along the arc direction of the fixed blade comb 6. The comb teeth 15 on the comb plate 16 are pulled outward. When the incomplete gear 17 separates from the complete gear 18, the drive wheel 14 cannot continue to rotate in the forward direction without external force. At this time, the spring 10 pulls the slider 13 to slide down and reset quickly, driving the comb plate 16 to slide down and reset quickly, driving the comb teeth 15 to slide down and penetrate into the gap of the blade teeth 7 of the fixed blade comb 6, thereby pushing out the meat (if any) in the gap and preventing the fixed blade comb 6 from being blocked.
