Supply machine for automatic disk change and splicing of tobacco sheets

Abstract

The invention provides a supply machine for automatic disk change and splicing of tobacco sheets. The supply machine comprises a rack; tobacco sheet disk clamping mechanisms which are respectively used for fixing and transmitting new and old tobacco sheets, a splicing mechanism which is used for splicing the new and old tobacco sheets, support wheel groups which are respectively used for supporting the new and old tobacco sheets and cutting mechanisms which are respectively used for cutting the head ends of the new tobacco sheets and the tail ends of the old tobacco sheets are arranged on therack. The supply machine is characterized in that guiding limiting mechanisms which are respectively used for limiting positions of the new and old tobacco sheets are arranged on the rack and in frontof the splicing mechanism; each guiding limiting mechanism comprises a seat body, on which a longitudinal through groove is formed; and the new and old tobacco sheets respectively pass through the longitudinal through grooves. The supply machine is capable of solving the problems that the tobacco filling amount is insufficient and the product quality is reduced as dislocation is caused during thesplicing in the prior art, and is proper in splicing thickness, high in strength, timely in tobacco sheet end separation, simple in structure, reliable in work and high in automation degree.

Description

technical field [0001] The invention relates to an automatic disc-changing and splicing supply machine, in particular to an automatic disc-changing and splicing supply machine for online tobacco sheets, belonging to the technical field of tobacco processing equipment. Background technique [0002] In the production process of the new strip-shaped tobacco sheet produced by the papermaking method, the strip-shaped tobacco sheet needs to be pretreated before being sent into the bong to be rolled into a tobacco stick. The pretreatment includes cutting, creasing, or cutting and creasing the ribbon-shaped tobacco sheet. Among them: 1) Slitting refers to: cutting a wide strip-shaped tobacco sheet into several narrow filaments with equal width along its running direction; 2) Indentation refers to: cutting a wide strip-shaped tobacco sheet 3) Slitting and indentation refers to alternately performing slitting and indentation on the same ribbon-shaped tobacco sheet. Since the tobacco...

AI Technical Summary

Problems solved by technology

However, based on the above-mentioned special properties of the tobacco sheet, when the existing automatic sheet changer is used to complete the splicing of new and old tobacco sheets, there will be the following relatively serious defects or deficiencies: 1) The width of the head end of the new tobacco sheet is the same as The width of the tail end of the old tobacco sheet is dislocated after splicing, and once it is dislocated, the misplaced part will be cut off in the subsequent cutting process, thereby reducing the filling amount of the final product and reducing the quality of the tobacco product; 2 ) in the splicing parts of new and old tobacco sheets is easy to thicken and cannot enter the post-order setting, but to eliminate the thickening must be extruded, and a little carelessness will cause the strength of the extruded part to decrease, so that it can be processed in the post-order Tobacco rods break during the process, which not only increases the amount of manual splicing, but also affects the quality of the final product; 3) After the splicing of new and old tobacco sheets is completed, it is difficult to immediately separate the head end of the new tobacco sheet and the tail end of the old tobacco sheet, thereby affecting normal production
