Abstract

A bag breaker for garbage bags features that a cylinder with more than 10 knives on its cirumference is obliquely arranged on a support platform to which the internal toothed rings are installed. A small gear is engaged with the said internal toothed ring. When the said cylinder is driven by a motor to rotate, the small gear and its axle are forced to rotate, so driving the knife installed to the said gear axle to rotate for cutting the garbage bag in the cylinder. Its advantages are high efficiency and small occupied ground area.

Description

Bag-crusher

Technical field

The present invention relates to a kind of sack that rubbish will be housed, by a cylinder that rotates, the cutter that rotate in the cylinder outside partly inserts in the cylinder, the device of rubbish sack in the cutting cylinder body.

Background technology

The application of bag-crusher is very wide, and particularly the bagging of house refuse is handled, and at present, the house refuse bagging is very universal, and need such as domestic garbage resource, minimizing tear plastic bag, are beneficial to the carrying out of subsequent technique; In existing bag-crusher equipment, it mainly is cutter by installing and fixing in the cylinder, or the cutter on two rollers carries out broken bag, refuse bag and cutter relative motion are less, the projectile motion of refuse bag in cylinder, destruction to cutter is serious, because cutter is fixed in the cylinder, has increased the difficulty of maintenance cutter.

Summary of the invention

The present invention includes platform, cylinder, electrical motor and speed reduction gearing on support and the support, cylinder places on the rack platform by supporting system, and cylinder has a leaning angle along horizon, and electrical motor is by drop-gear box and transmission gear, the drive cylinder rotates, around the cylindrical of cylinder, more than ten cutter is housed, cutter has part to stretch in the cylinder, the cylinder outside is set with internal gear, internal gear is rack-mount, and cutter is by cutter driving system driven rotary, refuse bag in the cutting cylinder;

At the support two ends, one group of supporting system respectively is housed, every group of supporting system has two wheel holding mechanisms, and cylinder is installed on this wheel holding mechanism, in the left side of two wheel holding mechanisms, idler mechanism is housed, and idle pulley contacts with the axial vertical scrolling of backing ring;

Described cutter driving system, be to place between internal gear and the cylinder, and be fixed on outside the cylinder, this driving system has a miniature gears and internal gear engagement, and cylinder rotates, and makes miniature gears and internal gear relative motion, force pinion rotation, and the axle rotation on the drive miniature gears, make the cutter on the tooth axle rotate the refuse bag in the cutting cylinder;

Described wheel holding mechanism, each support roller have a bearing, and support roller is fixed on the rack platform through bearing and bearing seat, and cylinder is installed on the support roller through backing ring, and support roller and backing ring are rolling touch;

Described idler mechanism comprises a backing ring, and backing ring is fixed on the cylinder outside, and idle pulley is fixed on the interior stepped shaft, and interior stepped shaft is fixed on the bearing seat, and bearing seat is fixed on the support;

This bag-crusher has increased the relative motion of cutter and rubbish, has improved the efficient of bag-crusher, has reduced the floor area of device, particularly since tool setting in the outside of cylinder, the maintenance cutter is than prior art convenient more.

drawing

1,2,3, on rack platform 2, cylinder 1 is housed, and cylinder 1 has a leaning angle, about 3-5 degree with horizon, a left side is low right high, right side charging, left side discharging is on cylinder 1, the rotating shaft 5 of cutter driving system 4 and driving system is housed, in the left side of supporting system, idle pulley 13 is housed, idle pulley 13 is to stop cylinder 1 to left side lower slippage, electrical motor 6 is through drop-gear box 7 and transmission gear 8 and drive cylinders 1 through gear 16 and rotate, cylinder 1 is installed on the supporting system, at the support two ends, one group of supporting system is housed respectively, every group of supporting system has two wheel holding mechanisms, cylinder is installed on this wheel holding mechanism, wheel holding mechanism by support roller 10 through bearing, bearing seat 9 is fixed on the rack platform 2, in the left side of two wheel holding mechanisms, idler mechanism is housed, and idle pulley 13 contacts with backing ring 15 axial vertical scrollings on the cylinder; Cutter driving system 4, be to place between internal gear 3 and the cylinder 11, and be fixed on cylinder 1 outside, this driving system 4 has a miniature gears 19 and internal gear 3 engagements, and cylinder 1 rotates, and makes miniature gears 19 and internal gear relative motion, force miniature gears 19 to rotate, and 5 rotations of the axle on the drive miniature gears 19, make the cutter 21 on the tooth axle 5 rotate the refuse bag in the cutting cylinder 1; See also accompanying drawing 5,, the rotation direction that becomes cutter 21 is cut from vertical direction, become the horizontal direction cutting by bevel gear 20 conversions.
