Description

Technical Field

[0001] The present application relates to the technical field of kneading machines, and in particular to a material cutting device at a material outlet of a silicone rubber kneading machine. Background Art

[0002] Kneading machine is an ideal equipment for kneading, mixing, vulcanizing and polymerizing high viscosity, elastic-plastic materials. It can be used to produce silicone rubber, sealant, hot melt adhesive, food glue base, pharmaceutical preparations, etc. Kneading machine often uses two M-shaped paddles, arranged in a side-by-side tangential differential speed type, that is, one stirring paddle has a fast speed and the other has a slow speed, so as to generate shear force. Different paddle speeds enable the mixed materials to be sheared quickly, so that the materials can be mixed evenly. Traditional kneading machines often use ball valve discharging or screw extrusion to discharge materials, so that the materials can be discharged more thoroughly.

[0003] After searching, the patent document with the authorization announcement number CN107471473A discloses a kneading machine discharging and cutting device, which mainly includes a kneading machine bottom, a kneading machine track, a rope fixing mechanism and a rope. There are two rows of kneading machine tracks, which are respectively installed on the upper surface of the kneading machine bottom. An inverted T-shaped groove is opened at the upper end of the kneading machine track. A scale is set on the upper surface of the kneading machine track. A rope fixing mechanism is connected to the upper end of the kneading machine track; there are four rope fixing mechanisms, each two of which are installed on two rows of kneading machine tracks in a group. A rotating shaft and a fixed seat are set at the upper end of the rope fixing mechanism. There are two fixed seats, which are symmetrically arranged at the upper end of the rope fixing mechanism. The rotating shaft is movably connected to the fixed seat respectively; there are four ropes, one end of the rope is fixed to the rotating shaft, and the other end is provided with a handle, and the four ropes are in a tic-tac-toe shape as a whole. The advantage is that it is very convenient to cut large pieces of rubber using four ropes arranged in a tic-tac-toe shape.

[0004] In actual use, it is found that the existing kneading machine cannot automatically transport the rubber material after cutting it, resulting in the accumulation of the cut rubber material at the discharge port. The rubber material needs to be collected manually, which increases labor costs and affects work efficiency. Therefore, we propose a silicone rubber kneading machine discharge port cutting device to solve the above problem. Utility Model Content
