Description

Technical Field

[0001] The utility model relates to the technical field of open mills, and more specifically, to an automatic rubber turning mechanism for an open mill. Background Art

[0002] An open mill is mainly used for further dispersing and mixing and plasticizing the components of the prepared ingredients and kneaded materials, thereby making plastic semi-finished products (such as tablets) or feeding a calender.

[0003] In the related art, in order to solve the problem that the mixed raw materials may sometimes be heavy and it is easy to cause imbalance of human balance in the case of manual throwing, the patent with the publication number CN220700119U in the prior art provides a rubber turning device for an open mill, which relates to the technical field of open mill turning equipment. The utility model includes an open mill body, and a turning equipment body is fixedly connected to the top of the open mill body. The turning equipment body includes a traction moving device and a roller extrusion device, and a mounting block is fixedly connected to one side surface of the open mill body.

[0004] Although the above-mentioned prior art solution finally achieves the purpose of turning the rubber without manually throwing the mixed raw materials into the turning equipment body through the cooperation of setting a small motor and a rotating shaft, however, the existing open mills with automatic rubber turning function can only perform one-way rubber turning, with a long rubber turning time and poor plasticizing effect, and also require manual cutting and traction. The too-high rubber turning structure needs to be manually lifted, which poses a safety hazard. During the initial feeding, some particles will fall off, and the large-area collecting tray is not convenient for subsequent centralized recovery.

[0005] In view of this, we propose an automatic rubber turning mechanism for an open mill. Content of the Utility Model

The rubber turning assembly 200 includes a concave plate bracket 210, the bottom end of the concave plate bracket 210 is fixedly arranged on the top wall of the two regulation boxes 112, a first motor 213 and a second motor 219 are arranged at the top of the concave plate bracket 210, the placement positions of the first motor 213 and the second motor 219 are opposite, and driving gears 214 are arranged at the output ends of the first motor 213 and the second motor 219. A rack plate 212 is meshed below the driving gears 214. When the first motor 213 is started, it drives the driving gear 214 to rotate, so that the rack plate 212 horizontally slides inside the first slide rail 211, drives the lower vertical rod 215 to horizontally act on the driving roller 114, and turns the rubber on the driving roller 114. After the vertical rod 215 turns once, it resets. When the second motor 219 is started, it drives the bending rod 218 to turn the rubber, so that the bending rod 218 and the vertical rod 215 turn the rubber alternately, avoiding the rubber surface from breaking due to turning inward simultaneously.

[0025] Further, first slide rails 211 are provided on both sides of the top end of the concave plate bracket 210, and one side of the two rack plates 212 slides inside the first slide rails 211 through sliding blocks. The first slide rails 211 drive the rack plates 212 to slide horizontally and stably. A support slide rod 216 is transversely arranged in the middle of the concave plate bracket 210. The bottom ends of the two rack plates 212 are respectively connected with a bent rod 218 and a vertical rod 215.

After the vertical rod 215 turns once, it resets. The second motor 219 is started to drive the turning of the bending rod 218, so that the bending rod 218 and the vertical rod 215 turn the rubber alternately, avoiding the fracture of the rubber surface caused by turning inwards at the same time. The dropped particles will enter the inside of the conical flow hopper 312. The holes below the conical flow hopper 312 are connected to the recovery box 311, and the particles are concentrated in the recovery box 311.
