Description

Coaxial type edge inserting film conveying device

Technical Field

The utility model relates to a coaxial formula is inserted limit membrane conveyor.

Background

The utility model relates to a conveyor for to insert the limit membrane and carry to the plastic bag and dash mouthful the operating position of machine or the folding strapper of plastic bag, make to be by the conveying insert the limit membrane and dash and cut into the portable shopping bag that has the handle state, perhaps further fold and tie up the shopping bag. The plastic shopping bag is formed by sealing and cutting a section of cylindrical plastic film, in order to increase the volume of a loaded object, the cylindrical plastic film is generally inserted and folded into an edge inserting film during film blowing, and the edge inserting film is characterized in that: the two sides (edge inserting areas) are 4 layers, the middle part is 2 layers, namely (two layers of areas), and a larger outer diameter can be obtained after the unfolding, so that the volume for holding articles is increased. The production of the shopping bags is completed by a bag making machine, a notching machine and a folding machine, wherein the bag making machine discharges dozens of strips of inserting edge films which are cut into sections onto a supporting plate in an intermittent mode after heating and sealing the two ends of the inserting edge films, the strips of inserting edge films are conveyed to the working position of the notching machine or the folding machine by an inserting edge film conveying device, the inserting edge films are cut off a notch similar to W to form the portable shopping bags with two handles, and then the portable shopping bags are conveyed to the working position of folding and bundling for folding and bundling. The prior art edge-inserting film conveying device comprises: the plastic bag punching and clamping device comprises a support and a rail, wherein the support is arranged on the rail in a sliding mode, the rail is arranged on a rack of a punching machine or a folding machine, a driving mechanism for driving the support to move back and forth along the rail is connected onto the support, a plurality of groups of clamping and clamping mechanisms for clamping plastic bags are further arranged on the support, each clamping mechanism comprises a clamping seat, a clamping arm, a clamping head, an air cylinder and the like, and the clamping seats and the clamping arms are made of aluminum alloy materials. Because the types of the plastic bags are more, the width, the thickness and the number of the plastic bags in each pile are different, some plastic bags are in a pile of 30, some plastic bags are in a pile of 80 or 100, and the types and the specifications are changed frequently. Therefore, the thickness difference between the two sides of the plastic bag and the middle two layers is difficult to estimate, and no rule can be followed. Therefore, the prior art inserting plate film conveying device is generally composed of at least 4 clamping mechanisms, the clamping mechanisms are arranged on the support at left and right intervals, the clamping mechanisms on two sides respectively clamp the inserting edge areas on two sides of the plastic bag, the clamping mechanism in the middle clamps the 2 layer area, and each clamping mechanism is respectively driven by a respective air cylinder, so that the rear end of the inserting edge film can be firmly clamped by the clamping pincers no matter the thickness difference of the inserting edge area (4 layers) or the two layer areas (2 layers).

The problems existing in the prior art are as follows: when the conveying device clamps the edge inserting film and conveys the edge inserting film to a preset position, the plurality of air cylinders are released to loosen the clamping plates, then the conveying device walks for a small distance (clamping the length of the rear side of the edge inserting film), the edge inserting film can be stopped after being put down, and then the conveying device returns. Because the clamping arms of each clamping mechanism are respectively driven by one cylinder, the cylinders are influenced by various factors such as air pressure, length of an air passage, friction force between a cylinder piston and a cylinder body and the like when being released, so that actual opening time of the cylinders is inconsistent, opening time of the clamping arms is inconsistent, when the clamping pliers clamp the edge inserting film to move, the edge inserting film inclines to one side, the placing position is inaccurate, and the subsequent work of a punching machine or a folding machine is seriously influenced.

Theoretically, the bracket and the clamping mechanism stay for a period of time, and the clamping arm continues to move backwards for a certain distance when the clamping arm is opened, but the stopping and restarting of the clamping mechanism needs a certain time, so that the production efficiency is influenced to a great extent; more importantly, when the clamping mechanism clamps the edge inserting film and stops, the front part of the edge inserting film moves forwards under the action of inertia force, the amplitude of the inertia movement is uncontrollable and irregular, the situation can even increase the error of the placement position, and therefore the edge inserting film conveying device in the prior art is driven by a plurality of clamping arms to be opened by respective cylinders in the walking process. The prior art has the following problems: the number of the cylinders is too large, so that the number of air pipes is too large, the structure is complex, and the manufacturing cost is increased.

As a further improvement, one or more U-shaped notches are arranged on the elastic steel plate, and two or more elastic clamping plates are formed on the whole elastic steel plate. For example: can form two elastic splint when setting up a U style of calligraphy breach on an elastic steel plate, can form 3 elastic splint when setting up two U style of calligraphy breachs, can form 4 elastic splint after setting up 3U style of calligraphy breachs. According to the design, the rear ends of the elastic clamping plates can be connected together, some elastic clamping plates correspond to the inserting edge area where the inserting edge touches, and some elastic clamping plates correspond to the two layers of areas, so that the connecting part of the elastic steel plate on the rear side can be twisted when the clamping inserting edge touches, elasticity is increased, the flexibility of the elastic clamping plates is also improved, and the installation and the fixation are convenient.
