Abstract
The utility model relates to a hot knife, the hot knife of side cut usefulness during in particular to crosslinked polyolefin foaming production. Including blade and blade holder, the blade passes through fastener and the locking of blade holder, the upper portion of blade holder is equipped with the blade heater, the blade heater contacts with the blade, the blade heater outside is equipped with adiabatic handle, the blade heater passes through the electric wire and links to each other with the heating control ware. The utility model discloses having reduced the wearing and tearing of blade, having improved the life of blade, prior art need change the blade in per 12 hours, the utility model discloses the life that can make the blade brings up to 15 days, easy operation, when putting into production, with the replacement cycle of blade location 14 days, the unedged production of avoiding of side cut improved product quality.
Description
Technical field
The utility model relates to a kind of hot knife, the hot knife of trimming when particularly a kind of crosslinking polyolefin foaming is produced.
Background technology
TPO plastic applications is extensive, and toughness, flexing and shock-absorbing capacity well, and have electric insulation, every thermal property, obtain apply comparatively widely in fields such as packaging, chemical industry and buildings.Cross-linked polyolefin is when producing, and need through foaming furnace foaming, product expands on thickness and width, and more than 1mm is without the online trimming of product needed of aft-loaded airfoil.The mode of current trimming is straight toolholder clip blade and rotating blade.The trimming mode of straight toolholder is simple to operate, but blade easily weares and teares, poor stability, often cuts out burr, affects product quality; The problem of rotating knife is that fixture is complicated, and operation, adjustment difficulty, when adjusting not in place, often cutting out arc-shaped side or toothed edge, affecting product quality equally.
Utility model content
In order to overcome the shortcoming of prior art, the utility model provides crosslinking polyolefin foaming hot knife, solves the product quality problem that Yin Qiebian brings, and improves the service life of straight knife blade.
Technical solutions of the utility model are as follows:
Crosslinking polyolefin foaming hot knife, comprise blade and blade drive rotaining device, described blade is locked by securing member and blade drive rotaining device, the top of described blade drive rotaining device is provided with blade heater, described blade heater contacts with blade, be provided with heat insulation bat-handle outside described blade heater, described blade heater is connected with heating controller by electric wire.
As preferably, described blade heater is heating rod, and the power of described heating rod is 50W.
As preferably, described heating controller is radiator valve, during use, keeps the temperature of blade at 60 DEG C.
The utility model beneficial effect is: the wearing and tearing 1) decreasing blade, improves the service life of blade, and prior art needs more allowing blade replacement in every 12 hours, and the utility model can make bring up to 15 days the service life of blade; 2) simple to operate, when producing, the replacement cycle of blade is located 14 days, and the generation of the trimming burr avoided, improves product quality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural representation.
Wherein: 1, blade; 2, blade drive rotaining device; 3, blade heater; 4, heat insulation bat-handle; 5, electric wire; 6, heating controller; 7, securing member.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult Fig. 1.
Crosslinking polyolefin foaming hot knife, comprise blade 1 and blade drive rotaining device 2, described blade 1 is locked by securing member 7 and blade drive rotaining device 2, the top of described blade drive rotaining device 2 is provided with blade heater 3, described blade heater 3 contacts with blade 1, be provided with heat insulation bat-handle 4 outside described blade heater 3, described blade heater 3 is connected with heating controller 6 by electric wire 5.
Described blade heater 3 is heating rod, and the power of described heating rod is 50W.
Described heating controller 6 is radiator valve, during use, keeps the temperature of blade 1 at 60 DEG C.
Utility model works principle is: the heating rod installing a 50W in the position that blade drive rotaining device 2 is close to blade 1, preheating 5 minutes before lower cutter, after lower cutter starts trimming, keep blade temperature at about 60 DEG C, the wearing and tearing of blade can be reduced, improve the service life of blade, during production, within every 14 days, change a blade, simple to operate, avoid trimming burr to produce, improve product quality.
Above-mentioned drawings and Examples are only for illustration of the utility model, and any art those of ordinary skill to its suitable change done or modification, or is used other flower pattern instead and made this technical change, all should be considered as not departing from the utility model patent category.
