Description
Technical field
The utility model relates to a kind of mechanical device, relates in particular to the quick effective plastic packaging machine of a kind of plastic packaging.
Background technology
The principle of plastic packaging machine is involutory plastic sheet to be packaged to be carried and through the gap between a pair of hot-rolling, by hot-rolling to its heating and with its encapsulation one.Traditional plastic packaging process is that the plastic packaging sheet is imported by guide-in roller, is heated the dish plastic packaging, is derived by outlet roller then.With glue,, do not need to add in addition again glue on the plastic packaging sheet through plastic packaging voluntarily after heating and the pressurization.This heating disc type plastic packaging method has been used for a long time, but the shortcoming of this plastic packaging method just is when the plastic packaging picture the very difficult bubble of eliminating.In order to address this problem, people have adopted hot-rolling formula plastic packaging machine, and the guide-in roller center is put into heater element and heated guide-in roller in machine, to eliminate bubble.In this plastic packaging machine system, roller carries out plastic packaging with heating and pressing mode to the plastic packaging sheet, and the roller in traditional heating disc type plastic packaging machine has only conduction function.Though but the plastic packaging machine of this structure can be eliminated bubble, in roller, put into the heating components and parts, make structure and install all to become very complicated, preheating time is also long, and is difficult to guarantee that the temperature of shell of compression keeps constant.Someone has applied for the patent of this spline structure: " a kind of hot-rolling heater (CN2552686) that is used for plastic packaging machine ", the electrical heating elements that it comprises a metallic support and is arranged on its back side, it is characterized in that the metallic support cross section roughly is the C font, electrical heating elements adopts the PTC heating component, and is embedded in longitudinally in the corresponding caulking groove of the metallic support back side one side.The plastic packaging machine of this structure has adopted the PTC heating element heater, and it is constant all the time on the PTC operating temperature to be heated temperature, is generally about 135 ℃ its outer additional configuration attemperating unit that need not.But the temperature constant of this structure plastic packaging, adjustable range is little.
Summary of the invention
The utility model mainly provides a kind of homogeneous heating, do not have bubble, greatly reduce preheating time, and the plastic packaging machine of the temperature stabilization of shell of compression, solving bubble appears easily after the heating of existing in prior technology plastic packaging machine, heating is uneven, and preheating time long technical problem.
It is a kind of simple in structure that the utility model provides simultaneously, is convenient to assembling, and cost is low, the plastic packaging machine that thermal loss is smaller; Solve existing plastic packaging machine complex structure in the prior art, be inconvenient to install the technical problem that thermal loss is big.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of plastic packaging machine, comprise the warm-up mill and the heater that are arranged on plastic packaging machine import department, be arranged on the outlet roller in exit, warm-up mill, heater and outlet roller all are provided with in pairs, described heater comprises heating plate and coupled cartridge heater, heating plate and cartridge heater are one, and heater element is arranged in the heating plate, and the bottom surface of heating plate is parallel to the plastic packaging sheet direction of motion; Be provided with the warm-up mill concentric with it in the cartridge heater, the surface of warm-up mill is provided with shell of compression, and the cross section of cartridge heater is " C " shape.Heater is arranged on outside the warm-up mill, is arranged in the heating plate with the cartridge heater integral production, not only can simplified structure, the convenient installation, simultaneously, plastic packaging machine can directly be passed to the warm-up mill surface to heat from hot conducting surface fast.Cartridge heater is " C " shape, better wraps warm-up mill, and better retaining heat shortens preheating time, also can be so that heating is more even.
As preferably, described heating plate is provided with a "T"-shaped groove, is provided with fixing hole at the excircle of cartridge heater."T"-shaped groove is set, can conveniently places heater element, the fixing hole in that its external peripheral surface is provided with can conveniently be fixed on heater on the support body.
As preferably, below warm-up mill and outlet roller, be equipped with regulating spring, spring housing is connected on the bolt, and bolt links to each other with pressure hook.Distance between two warm-up mills of adjustment that regulating spring can be suitable is set, in like manner also can adjusts two distances between the outlet roller.
As preferably, respectively be provided with an axle sleeve concentric at the two ends of warm-up mill with warm-up mill, axle sleeve is wrapped in the outer rim of warm-up mill, is provided with a boss that connects with heating roll shaft core in the axle sleeve, and boss is with annular pressure hook outward.Axle sleeve can prevent that with the end face parcel of warm-up mill heat runs off.Because spring bolt links to each other with pressure hook, pressure hook is socketed on the boss, and when adjusting spring, pressure hook drives axle sleeve because of the effect of spring can make progress or move down with this, thereby has driven the motion of two heating roll shaft cores.
As preferably, respectively be provided with an axle sleeve concentric with outlet roller at the two ends of outlet roller, axle sleeve is provided with a boss that connects with derivation roll shaft core, and boss is with annular pressure hook outward.Because being the plastic sheet that plastic packaging is good, the main purpose of outlet roller derives, so, axle sleeve does not need only to have needed the effect of fixed support just passable its parcel, and the adjustment of distance is identical principle between the adjustment of the distance between two outlet rollers and two warm-up mills.
As preferably, the shell of compression on warm-up mill surface adopts silicon rubber to make.Silicon rubber can keep suitable elasticity in the very big scope of variations in temperature, other rubber relatively, and its tensile strength, prolongation property, mar proofs etc. are all good than other rubber.It can be 300 ℃ or the above-mentioned performance of above maintenance, and serviceability temperature can arrive 250 ℃ continuously, and interrupted serviceability temperature can arrive 350 ℃, in 90 ℃ to 300 ℃ scopes, enough good elasticity is arranged after exerting pressure, and can return to original state.
Therefore, the utlity model has following advantage: 1. adopt the warm-up mill heating, can be very fast reach ideal temperature, preheating time is shorter relatively.2. in the plastic packaging process, by replenishing because the thermal loss that plastic packaging produces is easy to keep the temperature constant on warm-up mill surface to the direct-fired form in warm-up mill surface.Since heater element on heating plate, simple in structure, easy for installation.4. the employing spring is regulated the distance between a pair of warm-up mill, makes plastic packaging tightr; Adopt axle sleeve, not only can play a supporting role, and can well prevent the loss of heat.5. adopt silicon rubber as shell of compression, mar proof is better, and elasticity is also better.
