Description

A kind of tape cutter

The utility model relates to a kind of tape cutter, and is specifically a kind of during with the hot-melt pressure sensitive adhesive tape joint sealing, can heat adhesive tape bonding before, can compress and cut off the cutter of adhesive tape after joint sealing is bonding.

Most light industrial goods all be with packed in cases as the product of aspects such as toy, clothes, electronics, and the case lid of carton normally seal with tape.In the joint sealing process, the operator will cut off tape continually thereby use a kind of instrument of tape cutter to finish the task of compressing and cutting off adhesive tape.

Hot-fusible pressure-sensitive adhesive is a glue a kind of commonly used of making tape.When using the produced tape of glue of this character, be subjected to the restriction of the glass temperature and the inharmonious temperature of its glue: if the glass temperature of glue is too high, when then under low temperature environment, carrying out joint sealing, glue often causes its melt viscosity low inadequately because of ambient temperature is low, what cause " fail to stick " adherend (for example fail to stick carton case lid) or the joint sealing operation occurs has clung case lid at that time, but because of the melt viscosity of the glue of glue-line low inadequately, glue-line can not fully soak into bonding and the due bind strength of out of reach with the sticking mutually face of adherend, " coming unstuck " will take place after a period of time, " collapse case ", i.e. the phenomenon that has been flicked by stick box lid.

At present, the tape cutter of being on sale throughout on the market is powerless to elimination " fail to stick ", " collapsing case " phenomenon.The orthodox method that the case problem is collapsed in solution is the prescription that changes hot-fusible pressure-sensitive adhesive, and research is applicable to the low form hot-melt pressure sensitive adhesive tape of the low Tg under the low temperature environment.Reduce the melt viscosity of glue under low temperature environment of glue-line, improve the adhesive property of adhesive tape under low temperature environment, its cost is the serviceability temperature higher limit that the inharmonious temperature that reduced glue has promptly reduced adhesive tape, and the warm territory of the serviceability temperature of adhesive tape does not enlarge.The reduction of the inharmonious temperature of glue, its direct adverse consequences are that the bind strength of adhesive tape under hot environment declines to a great extent, and the resistance to effect of heat of glue will degenerate.The place to use of adhesive tape, environment for use temperature usually can't be determined.For example, the Packaging Box of goods has glued with low form tape envelope in colder area, be transported to the high area of southern temperature with goods, " hot melt " phenomenon promptly takes place in the hot-fusible pressure-sensitive adhesive on the low form tape, its melt viscosity reduces, it is thinning to be commonly called as glue, and " collapsing case " phenomenon also can take place the corresponding reduction of its bind strength.

When above-mentioned statement of facts uses the normal temperature type hot-melt pressure sensitive adhesive tape, be subjected to the restriction of the inharmonious temperature of its glue.In the torrid zone, when use in temperature higher area in subtropics, often higher because of ambient temperature, the glue of glue-line will " gummosis " phenomenon occur because of its hot melt, especially some adherend itself is exactly an exothermic body, adhesive tape uses a period of time in high any the environment of such temperature after, glue is because of the hot melt melt viscosity reduces, and causes its bind strength to descend and glue accelerated weathering and lose adhesion properties in hot environment, so actual requirement improves the inharmonious temperature of glue, improve adhesive tape serviceability temperature section.

Improve the inharmonious temperature of glue, the benefit that improves adhesive tape serviceability temperature section is that the glue of adhesive tape has good resistance to heat and ageing resistance under height, warm environment, has strong binding force and bind strength etc.The problem of bringing thus is that the also corresponding glass temperature that improves glue has improved the melt viscosity of glue under low temperature environment, the phenomenon of " fail to stick " will occur, even make adhesive tape lose Practical significance in the inharmonious temperature that improves glue.

The glass temperature of hot pressure sensitive adhesive and inharmonious temperature have been determined the use temperature territory of glue and have been constituted a very important contradiction.If require glue to have wide use temperature territory, all have gratifying adhesive property when using in the temperature range from the torrid zone to the frigid zone wide geographic area, the prescription that then will drop into human, financial, and material resources power adjustment glue enlarges the use temperature territory of glue.

The purpose of this utility model is to provide a kind of tape cutter, the prescription that it can not change glue can make normal temperature type, even megathermal hot-melt pressure sensitive adhesive tape is under the cold district low temperature environment, reduce the melting viscosity of adhesive tape gluing at short notice effectively, solve adhesive tape " fail to stick " under low temperature environment, the problem that " collapses case ", also can be able to normal utilization and can fully realize due bind strength of adhesive tape and the inharmonious temperature that helps to improve the new-type heat-melting pressure sensitive adhesive at the low temperature environment high temperature modification hot-melt pressure sensitive adhesive tape of ordering, enlarge the use temperature territory of adhesive tape, can solve aforementioned contradiction effectively.
