Description

Technical Field

[0001] The utility model belongs to the technical field of open mixing mills, and in particular relates to an automatic material guiding device under a roller of an open mixing mill. Background Art

[0002] A mixing mill is a mechanical equipment used for rubber and plastic processing. It is mainly used for mixing, plasticizing and calendering of materials. Generally, products such as natural rubber, synthetic rubber, ethylene-vinyl acetate copolymer, etc., which are vulcanized by a vulcanizer and injection molded by a new process, must be plasticized or mixed by a mixing mill.

[0003] After mixing the raw materials according to the specific technical requirements in the internal mixer, the raw materials and compound materials that were originally in the form of colloids, particles, and powders are fused and melted into agglomerates. However, the dispersion between the various compound materials and the rubber (plastic) in the raw materials is still very low, so an open mixer is required for further processing.

[0004] Traditional mixing mills are equipped with two relatively rotating rollers to extrude materials, and a collecting platform is set under the rollers to collect the processed materials. During the mixing process, workers are required to manually collect the heated materials after extrusion, which lacks practicality and safety. Utility Model Content

[0005] The utility model discloses an automatic material guiding device under a roller of an open mill, which mainly solves the problem of material accumulation in the mixing process of the current traditional open mill.

[0006] To achieve the above object, the utility model provides an automatic material guiding device under the roller of an open mill, comprising a base, a guide mechanism is arranged on the base, a pounding mechanism is slidably mounted on the base through the guide mechanism, the pounding mechanism comprises at least one pounding roller, and installation limit plates are symmetrically arranged at both ends of the base, and the guide mechanism comprises:

[0007] At least two guide rods arranged in parallel between the two mounting limit plates;

[0008] The two ends of the guide rack are respectively fixedly connected to the mounting limit plates, the bottom of the guide rack is fixedly connected to the base, and at least one side surface of the guide rack is provided with meshing teeth.

[0009] Preferably, the two ends of the base are provided with mounting limit plates, and two guide rods are provided between the two mounting limit plates. By providing at least two guide rods, a stable double-track support structure is formed, which is more resistant to torsional loads than a single-track design. This layout disperses the pressure of the tamping mechanism on a single rod, avoids wear and deformation after long-term use, and improves the overall life of the device.

[0010] Preferably, the pounding mechanism comprises a housing, a guide slider is arranged at the bottom of the housing, and the guide slider is slidably sleeved on the outside of the guide rod. The guide rod can provide a physical track for the reciprocating linear motion of the pounding mechanism, ensuring the accuracy and stability of the moving path.

[0011] Preferably, a moving motor is provided on the top of the shell, the output shaft of the moving motor extends out of the bottom of the shell and is provided with a moving gear, the output shaft is meshed with the guide rack through the moving gear, and the moving gear is driven to rotate and meshed with the guide rack by the moving motor, thereby driving the movement of the pounding mechanism.

[0012] Preferably, a pounding motor is further provided on one side of the shell, and an output shaft for driving a pounding roller to rotate is provided at the output end of the pounding motor, and the output shaft is connected to the pounding roller via a coupling.

[0013] Preferably, a guide rod seat is provided at the bottom of the guide rod.

[0014] Preferably, the mounting limit plate is provided with a mounting hole.

[0015] Preferably, the surface of the pounding roller is provided with an anti-sticking layer to prevent the adhesive from adhering to the surface and causing waste during operation.

[0016] Preferably, the surface of the pounding roller is provided with an anti-sticking layer, and the material of the anti-sticking layer is one of polytetrafluoroethylene or ceramic.

[0017] The technical solution provided by the utility model has at least the following technical effects:

[0018] The utility model provides a guiding mechanism and a pounding mechanism on the base, so that the materials after roller extrusion processing can be guided during the mixing process of the raw materials, thus avoiding manual processing and improving safety and work efficiency.

[0019] The utility model arranges a mobile motor on the pounding mechanism so that the position of the pounding roller can be adjusted according to actual use requirements, thereby enhancing applicability. BRIEF DESCRIPTION OF THE DRAWINGS
