Abstract

The utility model discloses a small automatic plastic bag making machine, which changes the number and the angle of a heat sealing piece on a heat sealing wheel to make more than five kinds of cylindrical single seal plastic bags via one machine. High productivity is realized by a rolling heat seal method. The automatic plastic bag-making machine having the advantages of simple structure, low cost and high productivity can be matched with a blow molding machine and can satisfy the manufacture of the cylindrical plastic bags having small sizes.

Description

The automatic plastic Bag Making Machine

The utility model is a kind ofly to relate to specially in blow moulding machine is supporting or independent the use, and to 90 millimeters to 350 millimeters of length, single automatically miniature high-speed plastic bag making machine tool of cutting that seals is carried out in the thin desert of the tubular plastics of width in 50 millimeters to 250 millimeters.

The polybag of above scope is used comparatively extensive on the inside and outside packing of food, manufactured goods, electronic product etc., and this class polybag of domestic production mainly leans on manual manufacture at present.It is reported, the automatic bag making machine of producing the small plastic bag specially but seldom, and the Bag Making Machine of domestic introduction is mainly produced large-size polybag and plastic bag.The introduction speculative investment is big, the expense height, and particularly some medium-sized and small enterprises are difficult to bear.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provide a kind of simple in structure, production efficiency is high, cost is low, can be with blow moulding machine supporting or independent the use, can produce the tubular list envelope polybag of different length, width more than five kinds on a machine, be a kind of small-sized automatic plastic Bag Making Machine.

The purpose of this utility model reaches by following measure.At first be that the tubular film band that will blow width is contained on the charging support, by the traction wheel that tilts to install tubular film band is sent into the heat seal wheel, heat-sealing sheet more than two to six is installed on the heat seal wheel as required, and [the heat-sealing sheet is to use nickel filament, heat-resistant insulation material is made] that is to say the quantity and the angle that on the outer garden of the heat seal of diameter wheel, change its heat-sealing sheet, just can be divided into halves to the heat-sealing sheet, three equal parts, quarter, five equal portions, the umber that waits that six equal portions are above is installed on the heat seal wheel, just can obtain the arc length more than five kinds, just can be made into different equidistant tubular list envelope polybags more than five kinds.When tubular film band enters between heat seal wheel and the rubber cushion wheel, heat-sealing sheet and rubber cushion take turns mutually to the motion synergy under, make the horizontal quilt of tubular film band equidistantly seal the heat-sealing line of 1-2 mm wide, enter water cooling again under the traction by traction wheel and make its heat-sealing back cooling and shaping.Enter at the tubular band that is heat-sealed under the traction of traction wheel and to cut between wheel takes turns with edge bearing, cut the blade, the edge bearing that are equipped with on the wheel and seal sheet equivalent amount and angle, two-wheeled is stained with foam and the soft rubber greater than this two tangent line simultaneously, the blade tangent line should with the heat-sealing line 2-5 millimeter that staggers, this two-wheeled mutually to the motion effect under, the polybag that is equidistantly cut into single one by one front cover limit by the tubular membrane band after the transversal heat seal, so just reach the purpose of automatic plastic bag.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structural front view of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the perspective view of heat seal wheel in the vertical plane;

Fig. 4 cuts the perspective view of wheel in the vertical plane.

The utility model will be described in further detail below in conjunction with implementing: this automatic plastic Bag Making Machine is by a stepless speed changer (1); Film traction wheel (2); Heat seal wheel (3); Heat-sealing sheet (5); Rubber cushion wheel (4); Water cooling (6); Cut wheel (11); Blade (10); Foam and soft rubber (9); Cut pad wheel (8); Edge bearing (7) constitutes the automatic plastic Bag Making Machine.Wherein on the parallel outer garden of heat seal wheel (3) axis, equally distributed heat-sealing sheet (5) is installed, (the heat-sealing sheet is to make with spring chromium silk and heat-resistant insulation material) tubular film is being sent under the effect of traction wheel (2) between heat seal wheel (3) and rubber cushion wheel (4) two-wheeled, seal into to the tubular film band horizontal equity of under the synergy of two-wheeled, it being sent into the heat-sealing line of 1-2 mm wide, wait umber and the angle that are evenly distributed on the heat-sealing sheet (5) on the outer garden parallel with heat seal wheel (3) axis like this have 5 kinds, just plastic sheeting tubular band can be made 5 kinds of heat-sealing lines that difference is equidistant.Film band after heat-sealing under the effect of traction wheel (2) passes through water cooling (6) with its cooling.Cut be equipped with on the outer garden of wheel (11) and heat seal wheel (3) on heat-sealing sheet (5) equivalent amount and the blade (10) of angle cut and be equipped with equally on the pad wheel (8) and the edge bearing (7) of blade (10) equivalent amount and angle and play a traction after the tubular plastic tape slitting and discrete being stained with between two flywheel knives and the cutter and between edge bearing and the edge bearing greater than the foam of two-wheeled line and soft rubber (9).Tangent line and the hot thread 2-5 millimeter that should stagger.

This automatic plastic system machine is like this work, and the tubular film zone circle that at first will blow width is contained on the support goes into the heat seal wheel by traction ShiShimonoseki of several groups of traction wheels, at this two-wheeled mutually under the effect to motion.Tube is closed the hot thread that a 1-2 millimeter is got up in the laterally equidistant heat seal of film band, pass through water cooling again, cooling and shaping, closing by traction wheel into cutting wheel, cut wheel, cut the blade on the pad wheel, heat-sealing sheet on edge bearing and the heat seal wheel is equivalent amount and angle, tangent line and hot thread should stagger the 2-5 millimeter under two-wheeled is stained with greater than the traction of the foam of two-wheeled tangent line and soft rubber by equidistant branch incision, so just cut into the polybag on tubular list front cover limit one by one.

The utility model is compared existing small-sized bag technology and is had following advantage: structure Simply, cost is low, and the production efficiency height can be raised labour productivity seven to ten times, can with Blow moulding machine supports the use, and the automaticity height is extensively practical.
