[0002] Fresh meat slicer is a kind of full-automatic food processing machinery to slice fresh meat, its working principle is that main motor drives lifting platform to lift, in this process, the driving gear on lifting platform is reciprocating rubbed by fixed rack, and the driving gear provides reciprocating rotary power for main shaft, then main shaft provides power for cutter head, knife grinder and meat conveying belt etc., this transmission mode can make cutter execute the following when passing fresh meat: 1, reciprocating sawing action of pulling driven by cutter head;2, lifting cutting action driven by lifting platform, by the cooperation of the above two actions, simulate manual fresh meat slicing action, ensure the "fish scale line" effect after fresh meat slicing, ensure that slice thickness, length and width are consistent.

[0003] Applicant has developed multiple generations of fresh meat slicing device, and has realized technology transformation and market promotion, including:

[0005] Second generation product: Chinese patent CN207070804U discloses a fresh meat slicing machine, which comprises a driving box body, a lifting cutting table, a cutting device, a feeding device, a discharging device and a driving device. The lifting cutting table is slidably installed on one side of the driving box body. The feeding device is arranged on the top of the driving box body. The driving device is arranged at the sliding connection between the lifting cutting table and the driving box body. The cutting device transversely penetrates the lifting cutting table. The discharging device is arranged inside the lifting cutting table. A driving motor is arranged in the driving box body. The driving motor drives the driving device to provide power for the lifting cutting table, the cutting device and the discharging device. A feeding motor is arranged in the driving box body. The feeding motor provides power for the feeding device. A clutch is further arranged on the feeding motor.

The driving of the feeding device is separated from the driving device of the slicing machine, thereby improving the service life of the machine.

[0006] After years of market use, the applicant found that the existing power system has the following problems:

[0007] 1. In the first and second generations of products, the diameter of the cutter disc changes when the cutter belt is wound. In order to keep the cutter belt in tension during reciprocating cutting, the transmission structure of the cutter disc has a variable shaft distance elastic self-adaptive function. However, this function has the problems of difficult cleaning and poor mechanical transmission connection stability in market use, including:

[0008] In the first generation product, the sliding bevel gear 17 and the capstan rotating rod 11 provide rotary power for the cutter disc. However, with the self-adaptive adjustment of the cutter disc shaft distance, the gear meshing connection position of the above two components is prone to damage, causing gear tooth damage. If the structure is further equipped with water spray cleaning function, it will greatly reduce the service life of the equipment.

[0009] In the second generation product, the main shaft and the cutter disc transmission shaft are connected by the moving cutter disc chain 15. However, the cutter discs on both sides are still connected by a shaft distance self-adaptive tensioning mechanism. The elongation of the chain is not uniform after long-term use, the synchronization of the cutter discs on both sides is poor, and the cutter belt is prone to loosen. In addition, under the condition of power connection of chain lubrication, the elastic self-adaptive tensioning mechanism of the cutter disc is difficult to realize water spray cleaning.

[0010] 2. Multiple sets of gears and chains are arranged in the overall power system. In actual operation, there is a deviation between gear transmission and chain transmission, which causes the error release position to be extremely dispersed. If the error is released to the gear, the gear teeth will be damaged. If the error is released to the chain, the chain will be elongated, and an additional chain tensioning mechanism needs to be provided.

[0011] In summary, how to design a multi-stage acceleration power system of fresh meat slicing machine, while ensuring the fixed axle distance driving the cutter rotating, with fixed point release error, becomes a technical problem to be solved in the field, and through comparative analysis, the technical scheme of the utility model is optimized and improved on the basis of the original technical scheme, which can prove its novelty.
