Description
Technical Field
The utility model relates to the technical field of film blowing, in particular to a plastic film bag making device.
Background
When manufacturing large-scale plastic square bags, hot-press edge sealing is needed to be carried out on two sides, so that the overall strength of the plastic bags is reinforced. In general, the edge sealing work is carried out by adopting a hot-melting welding device with a slidable bagging plate. For example, I disclose a plastic product hot-melt welding bagging device in China patent No. 202120015806.3.
The technical scheme has the following defects: the bagging plate is a plate matched with the shape of a plastic bag, the plastic bag is sleeved on the bagging plate, the inside of the plastic bag is divided into an upper part and a lower part, and although the two parts are not completely separated (two sides are still communicated), the air in the upper part of the plastic bag is rapidly extruded to the two sides due to the fact that the pressing speed of the pressing hot-pressing plate is high (the production efficiency is affected when the pressing speed is low), and the part to be hot-melted by the hot-pressing plate is just two sides of the plastic bag, so that the edge sealing effect is poor, and blank welding or bubbling often occurs at the edge sealing part. In addition, due to the adoption of the whole hot pressing plate corresponding to the bagging plate, although the heating pipes in the bag are arranged at two sides corresponding to the plastic bags, the whole hot pressing plate can rise to a higher temperature after a certain period of use, and the non-target positions of the plastic bags are easy to scald when the plastic bags are covered again.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a plastic film bag making device which can reduce the occurrence of empty welding and bubbling.
The technical scheme of the utility model is as follows:
the utility model provides a plastic film system bagging apparatus, it includes side bearer, slide rail, slider, bagging plate, portal frame, cylinder and bar hot pressing board, and the side bearer is established two and is welded down the mounting bracket between the two, is provided with a pair of slide rail on the mounting bracket down, installs the slider on the slide rail movably, and a connecting plate is installed jointly to two sliders, and a stand is installed vertically to connecting plate central authorities department, and stand top rigid coupling has a bagging plate, be provided with a plurality of bleeder vents on the bagging plate, the welding of side bearer top has last mounting bracket, and the backing plate is installed towards one side of bagging plate to last mounting bracket, and the portal frame is installed to one side of keeping away from the bagging plate, installs two cylinders on the portal frame, and the push rod of these two cylinders sets up down, and the push rod is connected with a movable frame jointly, and the movable frame below corresponds two backing plates and is provided with bar hot pressing board respectively, installs the heating pipe in the bar hot pressing board.
Further, the front end and the rear end of the sliding rail are provided with limiting mechanisms for preventing the sliding block from being separated from the sliding rail.
Further, the top surface of the bagging plate is flush with the top surface of the base plate, and the upper part of the plastic bag is positioned on a plane as much as possible during hot pressing, so that the formed edge sealing is smoother.
Further, the bagging plate is made of one of a fireproof wood plate (for example, a novel fireproof flame-retardant wood plate disclosed in China patent publication No. 202121245441. X), a high-temperature-resistant resin plate or a high-temperature-resistant rubber plate, and although the bagging plate is not in direct contact with a heating component, the possibility of accidental combustion can be obviously reduced by adopting the high-temperature-resistant material, and in addition, the problems of rust and the like of the materials are solved, and even if wet cloth is directly adopted for wiping, the cleaning is facilitated.
The beneficial effects of the utility model are as follows: the strip-shaped hot pressing plate does not press the bagging plate any more but acts on the backing plate, the strip-shaped hot pressing plate is divided into two sides corresponding to the plastic bags respectively, a large amount of air in the plastic bags is not easy to extrude towards the two sides when the strip-shaped hot pressing plate is pressed down, and the air on the upper side and the lower side of the bagging plate is communicated through the air holes in the bagging plate, so that the possibility that the air in the bags extrudes towards the two sides due to the fact that the movable frame is pressed down is further reduced, and the plastic bags are prevented from being hot-pressed and sealed to form blank welding or bubbling.

2) Pushing in the bagging plate, and arranging two sides of the plastic bag to be paved on the backing plate;
3) The cylinder pushes down, and bar hot pressing board presss from both sides on the plastic bag side on the backing plate, accomplishes the banding, because the movable frame is higher than the hot pressing board, so can not oppress the plastic bag generally, even has contacted the plastic bag, owing to be equipped with the bleeder vent on the bagging plate, the air of plastic bag top half also can not be in a large amount to gush out both sides, so can not cause empty welding or bubbling.
