Abstract
Description
Technical Field
[0001] This invention belongs to the field of tobacco machinery, specifically relating to an improved device and method for feeding a thin sheet into shreds in a rotary cutter. Background Technology
[0002] Thin sheet shredding is a processing requirement in the cigarette industry based on the unique flavor of new chilled thin sheets, utilizing existing rotary shredding equipment. The preceding process in existing thin sheet shredding technology is a thin sheet blending process, which involves adding blended tobacco sheets. Due to the influence of the thin sheets' own composition and structure, their hygroscopicity and processing characteristics differ from ordinary tobacco leaves, especially the degree of compaction, affecting whether existing rotary shredding machines can successfully shred the thin sheets. Existing rotary shredding machine thin sheet shredding feeding systems, such as... Figure 1 As shown in the diagram, the arrow points in the direction of the feed, meaning the feed direction is between the upper copper busbar chain (A) and the lower copper busbar chain (B). After being compacted by the upper and lower copper busbar chains, the material enters the rotary cutter for shredding. Existing rotary cutter shredding feeding systems have the following problems: the distance between the upper copper busbar chain (A) and the lower copper busbar chain (B) is fixed. Due to the different compositions and structures of different shredded materials, the feed thickness cannot be adjusted for different materials, resulting in varying degrees of compaction. This leads to different cutting loads on the cutter rollers of the rotary cutter, resulting in different shredding effects. Consequently, this leads to poor leaf pack formulation integrity and low effective utilization, thus affecting the quality of the finished cigarettes.
[0003] Improving existing rotary shredder equipment to adjust the feed thickness for different materials, thereby adjusting the compaction degree and turning different thin sheets into individual shreds to meet subsequent processing and technological requirements has become a major challenge. This invention addresses this issue. Summary of the Invention

The device of this invention, without changing the length and angle of the original upper and lower copper busbar chains, adds an adjustable-angle compaction device to change the material feed thickness, thereby adjusting the degree of material compaction. Using this device, the material is finally delivered to the cutting gate, and the gate height can be controlled, thus reducing the cutting load on the cutter rollers and laying the foundation for the successful filament formation of existing rotary cutter machines.

[0010] Preferably, the fixing device 3 is a mounting plate 31 with a waist hole 32; the mounting plate 31 opposite to the nylon block 131 has bolts 132 on its outer side.

[0029] The right side plate 11 and the left side plate 12 each have two toothed support rods 13 at their uppermost ends.
