Description

Combustion gas heat shrink films equipment

Technical field

The present invention relates to a kind of combustion gas heat shrink films equipment, belong to field of product packaging.

Background technology

At present; Existing thermal shrinking film packager mainly is made up of conveyer mechanism, the baking oven that is arranged at connecting gear belt conveyor top, the electrical bar that is arranged in the baking oven; Electrical bar is arranged on the below that reaches belt conveyor in the baking oven in the same way along the direction of transfer of connecting gear; The baking oven inner top also is provided with fortune wind blower fan, and in order to safeguard electrical bar, the baking oven of low profile thermal shrink packaging machine is turnover.Through baking oven, the thermal contraction at high temperature of the heat shrink films on the product packs tightly product to the product that conveyer is enclosed with oneself heat shrink films during use through load-transfer device.Therefore this kind heat shrink films machine, exists following shortcoming because electrical bar is a direction of transfer along connecting gear is arranged in the baking oven in the same way and the below of belt conveyor:

1, heat element generally adopts metal electric heat pipe or quartz glass tubular electric heating element; Usually cause straight tube; Two ends are for connecing electric screw rod, and the power supply link in hot case (comprising screw rod, nut, connecting ear, electric wire etc.) easy ageing, corrosion under hot environment cause the firmness of link impaired, break off or bad contact etc.; Cause heater temperature unstable, shrinker can't normal operation.

2, tubular electric heating element and link thereof leaky occurs easily and between body, and the shrinker fault is many, uses dangerous.3, because of the bad contact of tubular electric heating element link produces electro spark, the article of packing are produced bad infringement, even set off an explosion.

4, difficult in maintenance, need crawl in the baking oven (large-scale thermal shrinking film packager) when safeguarding or open baking oven, when safeguarding the tubular electric heating element below the load-transfer device, need take load-transfer device apart.

5,, and, cause product to receive heat shrinkable package inhomogeneous because of arrangement at regular intervals because tubular electric heating element and connecting gear transmit the direction of product shrink wrapping operation is installed in the same way under the interior and load-transfer device of baking oven.

6, when any certain tubular electric heating element bad contact or burn out when not working, influenced by it, this interval product asystole that is heated obviously appears, and product receives the obvious variation of heat shrinkable package effect, and shrink film shrinks rough.

7, shrinker need increase or be cumbersome when reducing heat-generating pipe, need reinstall equiblibrium mass distribution tubular electric heating element and fixed support thereof.

8, the load-transfer device of connecting gear is by axle branch and stainless (steel) wire band forms; Be arranged on the restriction that the row of one on chain metal shaft branch receives chain structure; The metal shaft branch is very thin, and in the time will handling heavy and large piece article (like a bale aluminium alloy extrusions), the metal shaft branch is pressed vault easily; Even drop, contact-impact damages the tubular electric heating element and the link of driving band below.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art, provide a kind of simple in structure, can improve heat shrinkable package effect, the article uniform combustion gas heat shrink films equipment that is heated.

The technical scheme that realizes the object of the invention is: a kind of combustion gas heat shrink films equipment; It comprises foot guide frame, S. A., driving device, lifting frame and heating up-down frame, and the foot guide frame comprises pedestal and the guide beam that lays respectively at the pedestal both sides, and actuating device is installed on the pedestal; Actuating device and S. A. flexibly connect; S. A. can be rotated to support on the guide beam, and S. A. is connected with lifting frame through driving device, and lifting frame is captiveed joint with heating up-down frame; On the heating up-down frame sets of burners that is centered around the heat shrink films periphery is installed, the Gas controller that is used for controlling sets of burners also is installed on the pedestal.

Further, described driving device is made up of chain and the sprocket wheel that is sleeved on the S. A., and chain and sprocket wheel are meshed, and captives joint with lifting frame in the two ends of chain.

Further, have guide groove on the described guide beam, the track adjusting wheel that can in guide groove, roll is installed on the described lifting frame.

Further, be provided with between described lifting frame and the described heating up-down frame and tiltedly draw reinforcement.

Further, described driving device has two, and the sprocket wheel of driving device is set in the two ends of S. A., and the chain of driving device is fixedly connected on the two ends of lifting frame respectively.

After having adopted technique scheme, the present invention adopts blue gas or natural fuels, under the accuracy control of Gas controller to the sets of burners ignition; In use compare safety; And sets of burners is to be centered around the outer article periphery that is surrounded by heat shrink films, makes that the shrink film of a circle can both obtain same heat energy around the sets of burners, and the shrink film that sets of burners makes on the article when moving up and down and wrapped up evenly shrinks from top to down; Make the shrink wrapping effect even more ideal, perfect; Compare with existing thermal shrinking film packager in addition, removed relatively heavier connecting gear, baking oven etc., make relatively simple for structure; And can realize again the packing effect of heat shrink films having reduced cost; Driving device of the present invention adopts the structural pattern of sprocket wheel and chain engages, makes lifting frame in the process that moves up and down, and velocity ratio is more steady, has further improved the thermal contraction effect; The cooperation of track adjusting wheel and guide groove makes lifting frame in the process that moves up and down, and shift variance can not occur, makes shrink film be heated evenly, has further improved the thermal contraction effect; Tiltedly draw being provided with of reinforcement to strengthen the power that is connected between lifting frame and the heating up-down frame, be unlikely to permanent use, heating up-down frame is because the gravity of self, and downward-sloping tendency occurs; Driving device respectively adopts one in both sides, also reached make lifting frame in the process of moving up and down than the pulsation-free effect, thereby further improve the thermal contraction effect.
