Smashing nail removing machine for building plastic formwork

Abstract

The invention provides a smashing nail removing machine for a building plastic formwork. The smashing nail removing machine comprises a support, a feeding platform, an upper cutter roller and a lower cutter roller. Multiple cutter discs are arranged on each of an upper cutter roller frame and a lower cutter roller frame at intervals, and each cutter disc is provided with multiple cutters. The cutter discs on the upper cutter roller frame and the cutter discs on the lower cutter roller frame are arranged at intervals and in a staggered mode. The axis of the upper cutter roller frame is higher than the feeding platform, and the axis of the lower cutter roller frame is lower than the feeding platform. Two ends of each of the upper and lower cutter roller frames are arranged on the support through bearing blocks. According to the smashing nail removing machine for the building plastic formwork, the building plastic formwork is pulled into the position between the upper cutter roller frame and the lower cutter roller frame through the feeding platform through different rotation speeds of the upper and lower cutter roller frames, the cutter rollers rotate to drive the cutter discs to rotate when the building formwork enters the position between the upper cutter roller and the lower cutter roller, and the cutters on the cutter discs cut and smash the formwork at different moments. Meanwhile, the cutter discs on the upper cutter roller frame and the cutter discs on the lower cutter roller frame are arranged at intervals and in the staggered mode so that nails in the building plastic formwork can be separated.

Description

technical field [0001] The invention relates to a building plastic formwork crushing and nail removal machine, which belongs to the technical field of building formwork crushing. Background technique [0002] With the rapid development of the construction industry, the status of formwork engineering has become increasingly prominent. Formwork technology directly affects the quality, cost and efficiency of engineering construction. At the same time, concepts such as green, low-carbon, and sustainable have gradually become hot spots in various engineering applications. In recent years, with the continuous development of the plastic industry, architectural plastic formwork has emerged as the times require, which combines the advantages of wood and plastic, such as weather resistance, reliability, environmental protection, convenience, and more importantly, recyclable reuse.

AI Technical Summary

Problems solved by technology

[0003] The existing separation and crushing equipment for plastic templates for construction has low efficiency and large dust, which is difficult to meet the needs of large-scale crushing. Most pulverizers install the moving knife blade on the cutter head and rotate with the cutter head, but the moving knife blade needs to be used. Cooperate with the cutting action of the fixed knife, and the impact and collision of the blade on the broken object to realize the crushing function

There are also some pulverizers that use the feeding mechanism to feed materials, and use multiple sets of electric saws to cut the boards. The saw blades are circularly cut and fed, which affects the efficiency of milling, and the power is high and the energy consumption is high.

In addition, many waste boards inevitably contain connectors such as iron nails, which are easy to damage the milling machine. The existing pulverizers and cutting machines cannot saw wood-plastic boards and profiles with nails.

At present, before cutting and crushing, the nails are manually pulled out, which is inefficient and labor-intensive

Iron nails are not easy to be screened and removed during milling and crushing, and will be mixed into wood flour products, affecting the subsequent milling process

[0004] The Chinese patent "Wood-plastic formwork powder making machine" (CN203916823U) discloses a powder making machine for building formwork. This patent drags the building plastic formwork into the pressure roller through the upper pressure roller and the lower pressure roller, and sends it to the crushing roller. The plastic formwork is crushed by the moving knife (column rod) on the crushing roller. This patent can crush the plastic formwork better, but the cost is high because the front end is equipped with a pressure roller. In addition, through the moving knife (cylindrical rod) Broken plastic formwork, loud noise

[0005] The Chinese patent "wood-plastic composite profile cutting machine" (CN203765681U) discloses a cutting machine for wood-plastic composite material profiles. This patent uses the upper and lower pressure rollers to drag the building plastic formwork into the pressure rollers. The plastic template is crushed by the saw blade. This patent uses a cutting saw, which is noisy
