Description

Technical Field

[0001] The utility model relates to the technical field of rubber material production equipment, in particular to a rubber mixing mill with a rapidly adjustable cutting device. Background Art

[0002] The mixing mill is mainly composed of rollers, a frame, a spacing device and a transmission device. The material is pulled into the gap between the two rollers rotating in opposite directions at different linear speeds under the action of friction. The material in the frame is subjected to strong shearing and extrusion through the gap between the rollers, which increases the temperature of the material and the plasticity, thereby achieving the purpose of rubber refining. It is used for operations such as plastic refining, mixing, sheeting and hot refining.

[0003] In order to optimize the process flow during the refining of some materials, it is necessary to directly cut the materials into preset sizes through a cutting device when discharging. The existing cutting device needs to use additional tools to set the cutting size during adjustment, and after setting, the cutting knife needs to be pressed down and kept in the pressed state before being fixed. This makes it more troublesome for one person to operate, and it is difficult to take into account both the accuracy of the size and the fixation of the cutting knife at the same time, which urgently needs to be improved.

[0004] In order to solve the deficiencies of the above-mentioned technology, the utility model provides a rubber mixing mill with a quickly adjustable cutting device, comprising a mixing mill body, a pair of pressure rollers, a pair of width plates, a discharging platform and a cutting device for discharging, wherein the pair of pressure rollers and the pair of width plates are both arranged on the mixing mill body, the discharging sleeve is arranged on the mixing mill body at a position below the pair of pressure rollers, the cutting device is arranged on the discharging platform, the cutting device comprises a pair of rotating cutting blades, a pair of mounting frames, a mounting rod and a rotating motor, the mounting rod is arranged on the mixing mill body and rotates with the mixing mill body, one end of the mounting rod is connected to the rotating motor, the pair of mounting frames are provided with mounting holes matching the mounting rods, the pair of mounting frames are both arranged on the mounting rods through the mounting holes and slideably match with the mounting rods, the pair of rotating cutting blades are respectively arranged on a pair of mounting frames, the pair of mounting frames are both provided with limiting screw holes connected with the mounting holes and limiting screws are arranged in the limiting screw holes, and the mounting rods are provided with limiting slide grooves matching the limiting screws.

[0005] By adopting the above technical scheme, a cutting device including a pair of rotating cutting blades, a pair of mounting frames, a mounting rod and a rotating motor is set, and a limiting slide groove is set on the mounting rod, so that after adjusting the spacing between the pair of cutting knives, the mounting frame as a whole can be limited between the mounting rod by the limiting screw. After the limitation of the pair of mounting frames is completed, the mounting rod is driven to rotate by the rotating motor to achieve the purpose of pressing down the cutting blade. During the entire adjustment process, every time the positioning of a cutting knife is completed, the mounting frame can be directly fixed without taking into account the specific positioning and pressing down at the same time, making the adjustment more convenient and easy.

[0006] The utility model is further configured as follows: the pair of mounting frames each include a main body block, a movable rod, a fixed plate and a tension spring; the fixed plate is fixedly connected to the main body block; one end of the movable rod is connected to the main body block and rotatably cooperates with the other end of the movable rod and is connected to the rotating cutting blade; the movable rod and the fixed plate are connected by a tension spring.

[0007] By adopting the above technical solution, since the pair of mounting frames include a main body block, a movable rod, a fixed plate and a tension spring, the fixed plate is fixedly connected to the main body block, one end of the movable rod is connected to the main body block and rotatably cooperates with it, and the other end is connected to the rotating cutting blade.

[0008] The utility model is further configured as follows: a distance sensor and a digital display screen are respectively arranged on the main body blocks of the pair of mounting frames.

[0009] By adopting the above technical solution, since the main blocks of the pair of mounting frames are respectively provided with distance sensors and digital display screens, the spacing between the pair of mounting frames can be quickly adjusted according to the discharge size, further improving the adjustment efficiency.

[0010] The utility model is further configured as follows: a cutting groove for facilitating cutting is provided at a position on the discharge platform corresponding to the pair of rotating cutting knives.

[0011] By adopting the above technical solution, since cutting grooves for facilitating cutting are provided at positions on the discharge platform corresponding to the pair of rotary cutters, the cutting depth of the rotary cutters is increased, further ensuring that the material can be completely cut during discharge.

[0017] By setting up a cutting device including a pair of rotating cutting blades, a pair of mounting frames, a mounting rod and a rotating motor, a limiting slide groove is set on the mounting rod, so that after adjusting the spacing between the pair of cutting blades, the mounting frame as a whole can be limited between the mounting rod by the limiting screw. After the limitation of the pair of mounting frames is completed, the mounting rod is driven to rotate by the rotating motor to achieve the purpose of pressing down the cutting blade. During the entire adjustment process, every time the positioning of a cutting blade is completed, the mounting frame can be directly fixed without taking into account the specific positioning and pressing down at the same time, making the adjustment more convenient and easy.
