Description

Technical Field

[0001] This utility model belongs to the field of strip cutting machine technology, specifically relating to a strip cutting mechanism for production and processing. Background Technology

[0002] In current processing and production, strip cutting is required to cut materials into multiple independent strips. This is generally done by a strip cutting machine, which uses multiple rotating blades to cut the material being transported through the blades into multiple strip structures.

[0003] Existing slitting mechanisms lack a buffer retraction structure for the blades, which may cause the blades to make hard contact with the material during instantaneous contact. This could affect the lifespan of the blades over time. Furthermore, in order to completely cut the material and form independent strip structures, the high-speed rotating blades must adhere to the conveyor belt, which may result in the blades hitting the conveyor belt and causing damage to it. Utility Model Content

[0004] The purpose of this invention is to provide a production and processing strip-cutting mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a production and processing strip cutting mechanism, comprising a pair of support seats symmetrically mounted on a conveyor frame, each pair of support seats having mutually aligned mounting slots, each mounting slot having a mounting slider longitudinally slidably mounted therein via a pair of guide posts, and a detachable rotating cutter shaft assembly being disposed between the pair of mounting sliders, each pair of guide posts having a buffer return spring sleeved on its upper end for pressing down and resetting the mounting slider, and a drive motor assembly for driving the rotating cutter shaft assembly being fixedly mounted on the outer side of one of the mounting sliders.

[0006] Preferably, the rotating cutter shaft assembly includes connecting shafts rotatably mounted on a pair of mounting sliders, and a cutter shaft located between the pair of connecting shafts. Each connecting shaft is provided with a threaded sleeve at one end corresponding to the cutter shaft, and the ends of the connecting shaft and the cutter shaft are screwed together by the threaded sleeve. Multiple blades that rotate synchronously with the cutter shaft are evenly distributed on the cutter shaft.

[0007] Preferably, the drive motor assembly includes a drive motor and a reduction gearbox respectively fixed on the mounting slider. The output shaft of the drive motor is connected to the input end of the reduction gearbox, and the output end of the reduction gearbox is synchronously rotatably connected to the connecting shaft on the corresponding side.

[0008] Preferably, the end of the connecting shaft is provided with a misaligned splicing protrusion A, and the end of the cutter shaft corresponding to it is provided with a misaligned splicing protrusion B that is complementary to the misaligned splicing protrusion A.

[0009] Preferably, the conveyor frame is provided with a conveyor belt with multiple grooves, and the grooves are aligned with the blades one by one. In the natural state, the bottom end of the blade extends into the groove; the conveyor belt is driven by a transmission conveying assembly.

[0010] Preferably, the transmission and conveying assembly includes a drive shaft and a driven shaft rotatably disposed at both ends of the conveyor frame, a conveyor belt drive sleeved on the drive shaft and the driven shaft, and a conveyor motor assembly fixedly installed on the outside of the conveyor frame. The conveyor motor assembly consists of a conveyor motor and a reduction gearbox B. The output end of the conveyor motor is drivenly connected to the input end of the reduction gearbox B, and the output end of the reduction gearbox B is drivenly connected to the drive shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The present invention features buffer components with buffering function at both ends of the cutter shaft. This allows the blade to retract and buffer when the material comes into contact with the blade during the cutting process. This avoids the hard contact between the blade and the material caused by the traditional fixed blade position, thus buffering and protecting the blade and ensuring its service life.

[0013] In addition, a strip-shaped groove aligned with the blade is designed on the conveyor belt, so that the bottom edge of the blade can extend into the groove and be below the level of the conveyor belt. This ensures that the material can be completely cut when cutting strips, and the groove design can prevent the blade from touching the conveyor belt, thus protecting the conveyor belt.
