Rubber extruding machine

Abstract

The invention relates to a rubber extrusion machine, comprising, a glue stock jar extending along an axis direction for accommodating the rubber material, a screw connection assembly, a compression screw bolt engaging with the screw connection assembly, a position limiting assembly for limiting the rotation of the compression screw bolt, and a driving assembly for driving the screw connection assembly rotate and powered by electric force, which produces the linear direction displacement of the compression screw bolt corresponding to the screw connection assembly, and squeezes the rubber raw material. The invention can be applied to obtain uniform character for the rubber raw material after extrusion and cutting.

Description

(1) Technical field [0001] The invention relates to a rubber extruder, in particular to a rubber extruder capable of controlling extrusion stroke and speed. (2) Background technology [0002] Such as figure 1 As shown, the general rubber extruder 1 (such as U.S. Patent No. 5,679,293, No. 5,486,104, No. 4,850,839, and No. 4,565,512, etc.) mainly has a rubber material cylinder 11 and an oil pressure cylinder for the accommodation of rubber raw materials. 12, and the cutter device 13 installed on one end side of the rubber cylinder 11. The hydraulic cylinder 12 has a piston rod 121 extending into the rubber cylinder 11 . In this way, when the oil pressure in the hydraulic cylinder 12 drives the piston rod 121 to advance, it will squeeze the rubber material in the rubber material cylinder 11, so that the rubber material is continuously squeezed out of the rubber material cylinder 11, and the cutter device 13 The rubber material protruding from the rubber material cylinder 11 ...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the temperature of the oil source in the hydraulic cylinder 12, the piston rod 121 will expand with heat and contract with cold, which will affect the travel speed of the piston rod 121, and when the rubber material 11 in the rubber cylinder 11 is large, the piston rod 121 will The resistance when pressing the rubber material 11 is relatively large, which will also affect the speed of the piston rod 121. Therefore, the speed of the piston rod 121 of the hydraulic cylinder 12 is not easy to control, so that the extrusion rate of the rubber material is different. Therefore, when the cutter device 13 continues to cut the rubber raw materials at the same speed, the thickness and weight of the cut rubber blocks will be uneven due to the different extrusion speeds of the piston rod 121, which requires manpower and time. , often adjust the travel speed of the hydraulic cylinder 12 piston rod 121 or the cutting rate of the cutter device 13

[0004] 2. Using the hydraulic cylinder 12 as a power source, in addition to generating large noise and exhaust gas, which will endanger the health of on-site workers, the waste oil produced by the hydraulic cylinder 12 cannot be recycled, so the industry must Please ask the environmental protection company to clean up and dispose of it, but there are still unscrupulous operators or environmental protection companies dumping or burying it everywhere, causing environmental pollution, which does not meet the needs of environmental protection
