Description

TECHNICAL FIELD

[0001] The utility model relates to food processing machinery technical field, concretely is a fresh meat slicing machine's fixed axle distance self tension cutting device. BACKGROUND

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

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

[0004] First generation product: Chinese patent CN105291154A discloses a fresh meat slicing device, including drive box, lifting cutting table, cutting device, feeding device and discharge device, lifting cutting table is slidably installed on one side of drive box, feeding device is arranged on the top of drive box, cutting device is transversely through lifting cutting table, and is rotatably connected with the dynamic knife winch arranged at the left and right ends of lifting cutting table;Discharge device is arranged at the corresponding position of cutting device and feeding device, motor is arranged in drive box, lifting cutting table is driven to move up and down by lifting drive device on the output end of motor, and simultaneously drives the rotation of dynamic knife winch.The invention overcomes the technical problem that traditional slicing machine cannot slice fresh meat, by adopting high-speed transverse cutting of strip-shaped dynamic knife and cutting mode of vertical displacement of lifting cutting table, simulating the cutting action of human hand on fresh meat, improving the slicing effect, saving manpower and improving the degree of automation.

[0005] Second-generation product: Chinese patent CN207070804U discloses a fresh meat slicer, including a driving box, a lifting cutting table, a cutting device, a feeding device, a discharging device and a driving device. A lifting cutting table is slidably installed on one side of the driving box, and a feeding device is provided on the top of the driving box. The driving device is arranged at the sliding connection between the lifting cutting table and the driving box, the cutting device passes through the lifting cutting table horizontally, and the discharging device is arranged inside the lifting cutting table; a driving motor is provided in the driving box, and 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 provided in the driving box, and the feeding motor provides power for the feeding device, and a clutch is also provided on the feeding motor; a speed regulator that can adjust the speed of the feeding motor is provided in the driving box. The machine overcomes the problems of high driving requirements for the feeding device and the risk of knife collapse. The feeding device drive is separated from the driving device of the slicer, which improves the service life of the machine.

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

[0007] 1. As a food processing machine, the transmission mechanism and food contact parts are not effectively isolated. Frequent cleaning can easily damage the lubrication of the transmission mechanism. Reducing the cleaning frequency can easily cause rotten meat to remain on the knife belt and knife disc due to the high temperature working environment in summer, which has an adverse impact on food safety.

[0008] 2. In the first and second generation products, the cutter disc diameter changes when the blade belt is wound. To keep the blade belt in a tensioned state during the reciprocating cutting process, the drive structure of the cutter disc has a variable wheelbase elastic adaptive function. However, this function has been verified in market use to be difficult to clean and has poor mechanical transmission connection stability. Among them:

[0009] In the first generation of products, the sliding bevel gear 17 and the capstan rotating rod 11 rotate to provide rotational power for the cutterhead. However, as the cutterhead wheelbase is adaptively adjusted, the gear meshing connection between the above two components is prone to collision damage, resulting in gear tooth damage. If a water spray cleaning function is added to this structure, the service life of the equipment will be greatly reduced.

[0010] In the second-generation product, the power connection between the main shaft and the cutter disc drive shaft is achieved through the movable cutter disc chain 15, but the cutter discs on both sides are still connected by a tensioning mechanism with adaptive wheelbase adjustment. After long-term use, the chain elongation range is different, the cutter discs on both sides have poor synchronization, and are prone to loss of rotation, which in turn causes the knife belt to loosen. Moreover, under the power connection condition of chain lubrication, the elastic adaptive tensioning mechanism of the cutter disc is difficult to achieve water spray cleaning.

[0011] In summary, how to design a fresh meat slicing machine fixed axle distance self-tension cutting device, in the cutting device has the waterproof spray cleaning function on the basis of ensuring its self-tension function, become the technical problem to be solved in the field personnel, and through the 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.
