Description

Technical Field

[0001] This utility model relates to the field of meat slicer technology, and in particular to a fresh meat slicer. Background Technology

[0002] In the fresh meat processing stage of the catering industry and food processing enterprises, slicing is a basic and high-frequency process, and its efficiency and quality directly affect the subsequent production process.

[0003] Currently, the industry mainly relies on two methods for slicing fresh meat: one is traditional manual meat cutting, where operators use knives or simple meat cutting tools to complete the slicing. This method not only requires a lot of manpower, but the thickness of the slices also depends entirely on human experience, which can easily lead to uneven thickness and uneven cut surfaces. At the same time, operators need to be in close contact with the blade for a long time, which poses a safety hazard of hand cuts. Especially in batch processing scenarios, the work efficiency is extremely low and it is difficult to meet production needs.

[0004] Another type is simple mechanical meat cutting equipment. Although such equipment can cut meat by rotating the blades with a motor, it generally has structural design defects: most of the equipment requires manual continuous pushing of meat pieces, and the pushing force and speed are not stable, so the slicing accuracy cannot be guaranteed.

[0011] In a preferred embodiment of this utility model, the disc cutting mechanism includes a cutting blade movably mounted on a cutting blade mounting plate, a driven wheel for the cutting blade shaft tail, a transmission protective cover on the back of the cutting blade mounting plate, a cutting disc drive motor inside the transmission protective cover, a driving wheel for the cutting disc at the drive end of the driving wheel, and a driving wheel for the cutting disc and the driven wheel for the cutting disc connected by a cutting disc synchronous belt.

The top of the main frame 1 is provided with a feeding bin 13, which contains a pushing mechanism 5 and a storage chamber 15. The top of the storage chamber 15 is provided with a protective cover 14. A human-machine interface 12 is provided on the side of the feeding bin 13. The pushing mechanism 5 includes a ball nut 50, and a hollow drive shaft 51 is provided on the back of the ball nut 50. The hollow drive shaft 51 is movably mounted in the feeding bin 13 through a bearing mounting seat 52. The ball nut 50 is located in the storage chamber 15. A driven synchronous pulley is provided on the back of the hollow drive shaft 51. 53. A feeding servo motor 58 is installed on the crossbar inside the main frame 1. The feeding servo motor 58 is located below the feeding hopper 13. An active synchronous wheel 59 is provided on the transmission end of the feeding servo motor 58. The active synchronous wheel 59 and the driven synchronous wheel 53 are connected by a feeding synchronous belt 510. A ball screw 54 is provided on the internal thread of the ball nut 50. A pusher connecting plate 55 is provided on the top of one end of the ball screw 54 located in the storage cavity 15. The pusher connecting plate 55 is connected to the pusher plate 57 by several screws 56.

[0019] When using the equipment, first open the protective cover 14 on the top of the storage chamber 15, and place the chunks of fresh meat to be cut flat in the storage chamber 15, ensuring that there are no foreign objects in the meat and that the position is aligned with the pusher plate 57; then close the protective cover 14 and check its locking status to prevent the meat from shifting or the fragments from flying during operation; finally, through the human-machine interface 12 on the side of the feed hopper, set parameters such as slicing thickness and conveying speed as required, and after completing the parameter settings, click the start button to put the equipment into the operation ready state. After startup, each mechanism operates in coordination according to the preset program. The reciprocating drive motor 25 at the bottom of the main frame is powered on and runs, driving the eccentric handle 26 at its transmission end to make circular motion. The eccentric handle 26 converts the circular motion into the linear motion of the vertical linear guide rail 20 through the hinged drive linkage 27, so that the two vertical linear guide rails 20 slide up and down along the linear guide rail slider 10, providing the up and down motion power required for cutting the disc cutting mechanism 4. When the disc cutting mechanism is started, the cutter head drive motor 43 on the back of the cutting disc mounting plate starts synchronously. The cutter head drive wheel 44 at its transmission end drives the cutter head driven wheel 41 to rotate at high speed through the cutter head synchronous belt 45. The cutting disc 40, which is coaxially connected to the cutter head driven wheel 41, rotates accordingly, forming a continuous cutting blade movement trajectory. The feeding servo motor 58 below the feeding hopper operates, driving the active synchronous wheel 59 to rotate. The active synchronous wheel 59 drives the driven synchronous wheel 53 to rotate through the feeding synchronous belt 510. The hollow transmission shaft 51, which is fixed to the driven synchronous wheel 53, rotates accordingly, thereby driving the ball nut 50 at its front end to rotate. The ball nut 50 and the ball screw 54 are threaded together. When the ball nut 50 rotates, it drives the ball screw 54 to move forward smoothly along the storage cavity 15. The front end of the ball screw 54 is connected to the push plate 57 through the push head connecting plate, which synchronously pushes the meat block in the storage cavity 15 to move forward slowly. The moving distance is precisely matched with the preset slice thickness. The overall slicing process adopts an intermittent feeding and synchronous cutting mode. The pushing and pushing mechanism 5 pushes the meat block forward precisely once according to the set thickness and then pauses. At this time, the cutting drive module 2 drives the disc cutting mechanism 4 to move downward. The high-speed rotating cutting disc 40 contacts the forward-moving meat block and completes one slicing operation instantly. After slicing, the cutting drive module 2 drives the disc cutting mechanism 4 to reset upward, and the pushing and pushing mechanism 5 feeds again. This cycle is repeated to achieve continuous slicing. The cut fresh meat slices slide from the discharge plate 315 on the back of the conveyor belt mounting plate 33 to the conveyor belt 35 below under the action of gravity. Meanwhile, the conveying motor 38 of the material conveying mechanism 3 continues to operate, and the driving pulley 39 at its transmission end drives the driven pulley 36 to rotate through the conveying synchronous belt 310. The conveyor belt 35, which is linked with the driven pulley 36, maintains a constant speed. The fresh meat slices that slide onto the conveyor belt 35 move with the conveyor belt 35 and are eventually conveyed to the pre-set loading basin below the equipment, realizing the automatic collection of slices without manual intervention. After a batch of fresh meat is cut, first turn off the power to the equipment via the human-machine interface 12. If it is necessary to clean the disc cutting mechanism 4, first remove the two set screws 314 on the conveyor mounting plate to disengage the clamping block from the guide baffle. Then, manually pull the adjusting screw 312. The adjusting screw 312 drives the conveyor belt mounting plate 33 to move backward through the locking block. The linear slider 32 at the bottom of the conveyor belt mounting plate 33 slides smoothly along the longitudinal linear guide rail 31 until the disc cutting mechanism 4 is fully exposed. At this time, the cutting blade 40, the cutting blade mounting plate, and other components can be cleaned. After cleaning, push the conveyor belt mounting plate 33 back to reset, reinstall the set screws 314 to fix the clamping block, and the equipment returns to the ready-to-operate state.
