Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing equipment, in particular to a rubber supply conveyor belt cutting machine for a mixing mill. Background Art

[0002] The open mill is a kind of mixing plastic equipment that was used earlier by plastic product manufacturers. On the calender production line, the open mill is before the calender and after the mixer. Its function is to mix and plasticize the uniformly mixed raw materials, and provide a relatively uniformly mixed and plasticized molten material for the calender to calender and mold plastic products. When producing cable materials, the open mill can directly refine and plasticize the powdered materials mixed according to the formula into molten materials, and then press them into sheet strips, so that the pelletizer can cut them into granules. On the floor leather production line, it can directly provide a uniformly mixed and plasticized base coating for the cloth leather. The recycled waste plastic film (sheet) can also be re-refined and plasticized on the open mill.

[0003] When the mixing mill processes rubber, it needs to cut the rubber into blocks to facilitate subsequent processing. However, due to the characteristics of rubber materials, the actual cutting may not be thorough and multiple cutting is required, which seriously affects the cutting efficiency.
