Description

Technical Field

[0001] This utility model relates to an automatic fresh meat slicer with a reciprocating motion, imitating manual operation, and belongs to the field of meat processing machinery technology. Background Technology

[0002] With the continuous advancement of technology and the increasing demands for quality of life, the meat processing industry is gradually growing and expanding, leading to a continuous increase in the demand for meat processing machinery. Among these machines, the fresh meat slicer is a particularly important piece of equipment.

[0003] A fresh meat slicer is a machine that cuts meat into slices of a specified thickness. The most common types of fresh meat slicers are the circular blade type and the slicing type.

[0004] Circular blade meat slicers have inconsistent cutting results, potentially leading to uneven slice thickness and excessive meat fragments, affecting the quality of the finished product. Maintenance costs are also high, as the blades require regular sharpening and replacement, which can put significant financial strain on small businesses. For example, sharpening a blade costs 20 yuan, and replacing a blade costs 3000 yuan. Some models lack flexible slice thickness adjustment, failing to meet diverse slicing needs. Furthermore, the circular blades are very sharp, posing a risk of injury during operation and cleaning. Additionally, the blades of these slicers can easily loosen, affecting cutting results and causing meat to get stuck during slicing. Utility Model Content

[0005] This invention provides a reciprocating automatic fresh meat slicer that mimics manual operation, solving the problems existing in the background art.

[0006] This utility model relates to a reciprocating, manual-style automatic fresh meat slicer, including a cutting table, a meat box, a meat feeding mechanism, a lifting frame, a lifting drive mechanism, an outlet baffle, a cutting blade assembly, a receiving conveyor belt, and two blade winches. The blade winches are connected to a reciprocating drive mechanism that drives their rotation individually. The cutting blade assembly includes an upper clamping plate and a lower clamping plate fixed on the lifting frame. A cutting gap is provided between the upper and lower clamping plates. A cutting blade with both ends connected to the blade winches is provided at the cutting gap. A pair of tensioning plastic rollers are provided at both ends of the cutting blade. A clamping plastic plate is provided on the outside of the cutting gap and is fixed on the upper clamping plate. A pushing arc is provided at the bottom of the clamping plastic plate, and a guiding slope with an inner higher and outer lower shape is provided at the top of the lower clamping plate.

[0007] As a preferred embodiment, the meat box is fixed on the meat cutting table, the meat box is connected to the meat feeding mechanism, the lifting frame is set on the front side of the meat cutting table and can be raised and lowered, the lifting frame is connected to the lifting drive mechanism, the front end of the meat box is fixed with an outlet baffle, the cutting assembly is installed on the lifting frame outside the outlet baffle, and the front side of the cutting assembly is provided with a receiving conveyor belt.

[0008] As a preferred embodiment, the frame of the receiving conveyor belt is detachably fixed to the lifting frame with bolts, facilitating disassembly, cleaning, or replacement later. A receiving motor is fixed to the lifting frame, and a synchronous shaft is rotatably mounted on it. The output shaft of the receiving motor connects the synchronous shaft and the receiving conveyor belt via a synchronous pulley assembly and a synchronous belt. Both ends of the synchronous shaft are connected to a drive shaft via a synchronous pulley assembly and a synchronous belt. The drive shaft is connected to a grinding shaft via a pair of bevel gears. The grinding shaft is rotatably mounted on the lifting frame, and a grinding roller is fixed to the end of the grinding shaft near the cutter assembly. The receiving motor simultaneously drives the receiving conveyor belt and the grinding roller through a synchronous structure, eliminating the need for an additional grinding drive component and simplifying the equipment structure. The grinding roller can synchronously grind the meat cutting blades during the receiving action, avoiding downtime due to dull blades and ensuring continuous processing.

[0009] As a preferred embodiment, two tensioning plastic rollers in the same pair are rotatably mounted with an adjusting frame plate. The adjusting frame plate has strip-shaped adjusting holes along the meat feeding direction, and adjusting bolts are installed in the strip-shaped adjusting holes. The adjusting bolts fix the adjusting frame plate to the lifting frame. The strip-shaped adjusting holes on the adjusting frame plate can adjust the position of the tensioning plastic rollers along the meat feeding direction, thereby flexibly adjusting the tension of the meat cutting blade to adapt to the needs of slicing fresh meat with different hardness and thickness. The adjusting bolt fixing method is simple to operate, and the tension can be adjusted without disassembling other parts, reducing the difficulty of operation.

[0010] As a preferred embodiment, the reciprocating drive mechanism includes driven sprockets fixed to the bottom of the shafts of the blade winches at both ends. The two driven sprockets are connected by a chain, which is connected to a driving sprocket. The driving sprocket is connected to a reciprocating drive motor, which is fixed on the lifting frame. A separate reciprocating drive motor can independently control the blade rotation speed, adapting to different slicing efficiency requirements, offering greater flexibility, and facilitating later maintenance.

[0011] As a preferred embodiment, the upper clamping plate has a clamping pressure plate on its outer side to press the clamping plastic plate. The bottom of the upper clamping plate has a positioning recess, and the lower end of the clamping plastic plate has a positioning boss that mates with the positioning recess. The lower end of the clamping pressure plate has a pressing boss that presses against the outer side of the clamping plastic plate. The positioning recess and positioning boss work together to quickly and accurately position the clamping plastic plate, preventing misalignment during installation and ensuring proper slicing. The pressing boss of the clamping pressure plate can fix the clamping plastic plate from the outside, improving the overall stability of the cutting assembly. Positioning and pressing are achieved through a mechanical structure, eliminating the need for adhesives or other auxiliary components, facilitating future replacement and maintenance of the clamping plastic plate.

[0012] As a preferred design, the upper clamping plate, lower clamping plate, and clamping pressure plate are all equipped with vertically oriented slots, each containing a fastening bolt that secures the device to the lifting frame. These vertical slots allow the upper clamping plate, lower clamping plate, and clamping pressure plate to move up and down, thereby adjusting the cutting distance and accommodating different slicing thicknesses, thus broadening its applicability. After adjustment, simply tightening the bolts locks the position, making operation convenient.

[0013] As a preferred option, the lifting frame corresponding to the inner side of the cutting spacing is provided with an embedded groove, and a wear-resistant pad is fixed in the embedded groove. The wear-resistant pad can isolate the meat cutting blade from the lifting frame, preventing the blade from directly rubbing against the lifting frame during the cyclical movement, thus reducing equipment wear; the embedded groove fixing method can prevent the wear-resistant pad from shifting, ensuring that it always fits against the inner side of the cutting spacing, and the protective effect is more stable; the wear-resistant pad material has high hardness and long service life, which can reduce the maintenance frequency of the lifting frame and blade, and reduce the operating cost.

[0014] As a preferred design, the meat container has an open top with a placement slot on the inner side of the top. A cover plate is placed within the placement slot, and a limiting block is located on the top of the front end of the cover plate on the outlet baffle. A limiting shaft is fixed to the outer wall of the meat container, and a limiting pressure plate is fitted onto the upper end of the limiting shaft to press down on the cover plate. A tightening nut, threaded onto the limiting shaft, is located above the limiting pressure plate. The open-top design of the meat container facilitates quick and easy placement of fresh meat, improving feeding efficiency. The placement slot positions the cover plate, and the limiting block on the outlet baffle prevents the cover plate from shifting vertically. The limiting pressure plate, in conjunction with the tightening nut, firmly presses the cover plate against the top of the fresh meat, preventing the meat from bulging upwards due to vibration during slicing and ensuring stable feeding.

[0015] As a preferred embodiment, the meat feeding mechanism includes a meat pushing plate housed within a meat container. A meat pushing guide rod is fixed to the rear end of the meat pushing plate. A guide sleeve is fitted over the outer end of the meat pushing guide rod, and a connecting frame is fixed to the outer end of the guide rod. A guide slider is fixedly connected to the connecting frame, and the guide slider is connected to a guide rail fixed to the cutting table. The guide slider is connected to a ball screw nut, which is connected to a lead screw. The lead screw is rotatably mounted on a lifting platform and connected to a meat pushing motor fixed to the cutting table. Limit switches connecting the lead screw to the meat pushing motor are located at both ends of the lead screw. The lead screw and ball screw nut provide high transmission precision, enabling the meat pushing plate to push the fresh meat at a uniform speed, ensuring even slice thickness. The double-guided structure, with the guide rod and guide sleeve working together and the guide slider and guide rail working together, restricts the direction of movement of the meat pushing plate, preventing deviation during pushing. The limit switches automatically control the start and stop of the meat pushing motor and can automatically return to their original position for convenient and rapid reloading.

[0016] This utility model has the following beneficial effects: The reciprocating drive mechanism independently drives the blade winch, which is convenient for maintenance. In conjunction with the lifting frame, it drives the cutting blade assembly to move up and down, which can accurately simulate the reciprocating motion of manual slicing and reduce meat breakage. The tensioning plastic roller can adjust the tension of the meat cutting blade in real time to ensure that the blade cuts flat and improves the slicing accuracy. The pushing arc can assist the fresh meat slices to be discharged, and the inner high and outer low guiding slope can guide the cut meat slices to slide out smoothly, preventing the meat slices from breaking at the edges and getting stuck.

[0023] Two tensioning plastic rollers 16 of the same pair are rotatably mounted with adjusting plates. The adjusting plates have strip-shaped adjusting holes along the direction of the meat feeding, and adjusting bolts are installed in the strip-shaped adjusting holes. The adjusting bolts fix the adjusting plates to the lifting frame 11. Before operation, the adjusting bolts can be loosened to move the adjusting plates back and forth, thereby moving the two tensioning plastic rollers 16 back and forth to tension the blades. After adjustment, the adjusting bolts are tightened.
