Automatic blank cutter for rigid plastic

Abstract

The invention provides an automatic blank cutter for rigid plastic, which mainly consists of a plurality of parts of a rack, a blank cutting steel wire rack track frame, a main transmission device, a blank transporting platform, a blank cutting steel wire rack and a blank cutting steel wire rack traction device. A pneumatic clutch which can be frequently started and braked is adopted as a speed reducer of the main transmission device; after the blank cutting steel wire rack with a double-steel wire blank cutting station is adopted, the blank cutting steel wire rack blank cutting stations can be automatically changed when a blank cutting steel wire is broken; the blank transporting platform adopts a stroke-adjustable air cylinder, so that the lifting height of a roller support can be conveniently controlled; the rack of the blank cutter is wholly welded by hollow square steel, so that the blank cutter is very good in stability and rigidity, and the cutting requirement of a rigid plastic extrusion molding blank body can be met; and due to the use of a linear guide rail pair, the moving precision and the moving stability of the blank body can be improved. The automatic blank cutter for the for rigid plastic is simple in structure, stable to run, reliable in performance, high in automaticity, and suitable for cutting the large-batch rigid plastic extrusion molding mud stripes.

Description

technical field [0001] The invention relates to a building material production machine, in particular to a device for automatically cutting brick adobes in the brick production process. Background technique [0002] At present, the blank cutting machines commonly used by domestic and foreign brick-making enterprises mainly have the following deficiencies: one is that the main drive has defects. The main drive of the existing billet cutting machine usually adopts three kinds of transmission modes, that is, the main drive adopts a jaw clutch, which frequently engages and separates during use, causing the clutch to wear out, and the maintenance is inconvenient, time-consuming and labor-intensive; the main drive adopts an electromagnetic brake or The brake belt driven by the cylinder performs forced braking. Under frequent braking conditions, the life of the electromagnetic brake and the brake belt is short, and the impact on the equipment is large, which increases the maintenan...

AI Technical Summary

Problems solved by technology

The main drive of the existing billet cutting machine usually adopts three kinds of transmission modes, that is, the main drive adopts a jaw clutch, which frequently engages and separates during use, causing the clutch to wear out, and the maintenance is inconvenient, time-consuming and labor-intensive; the main drive adopts an electromagnetic brake or The brake belt driven by the cylinder performs forced braking. Under frequent braking conditions, the life of the electromagnetic brake and the brake belt is short, and the impact on the equipment is large, which increases the maintenance cost of the equipment. The main drive uses a brake motor for forced braking. Under dynamic conditions, the motor is prone to heat and burnt

The above transmission methods cannot solve the technical problems of high cutting frequency and short cycle of large-volume billet cutting machine

Second, it is not easy to replace the broken cutting wire, which affects the continuous operation of the production line

The blank cutting wire frame usually equipped with the existing blank cutting machine has only one steel wire blank cutting station. After the cutting steel wire is broken, it needs to be stopped to replace the cutting steel wire, which affects the continuous operation of the production line.

Although some blank cutting machines are equipped with two steel wire blank cutting stations, when the cutting steel wire breaks, the operator needs to find out in time and manually push the blank cutting wire frame to replace the steel wire blank cutting station. Heavy, usually requires more than two people to push together, neither timely nor convenient

The third is that when the elevation of the equipment changes due to the production of brick products of different specifications, the elevation of the equipment is not easy to adjust

When producing brick products with different specifications, the elevation of the equipment often changes. Usually, a series of equipment needs to be adjusted to meet the needs of production. It is inconvenient to implement, time-consuming and labor-intensive. As an important equipment in the production line, the blank cutting machine should Optimize the design of the structure and reduce the equipment that needs to be adjusted to improve work efficiency

Fourth, the rigidity of the blank cutting machine frame is insufficient, which cannot meet the cutting requirements of hard plastic extrusion molding blanks

When using coal gangue and other hard raw materials for hard plastic extrusion molding, due to the high extrusion pressure and high strength of the green body, the rigidity of the blank cutting machine frame is generally insufficient, and the deformation is serious during the cutting process, which seriously affects the cutting of the green body. Quality, which brings hidden dangers to the safe operation of equipment

After consulting the relevant literature, there is no domestic technology and equipment similar to the present invention for publicity
