Description
Technical Field
The utility model particularly relates to a plastics express delivery bag seals with limit sealing mechanism.
Background
The packaging film mainly suitable for the existing edge sealing equipment in the market is mainly a shrink film made of POF and PE materials, and the two materials are good in flexibility and easy to heat seal and seal, so that the packaging film is a mainstream material for packaging the film at present, but the cost is high. The express packaging is non-shrink packaging with low cost, and the main requirements are 'low cost, firm sealing and packaging mode which can meet the packaging requirement'. The plastic packaging bag material used conventionally is mainly a recycled blend of PE and PO, which is cheap. But the phenomenon that the edge sealing line is not firm can occur when the existing edge sealing equipment is adopted. The express package using the materials is mainly packaged in the following three ways in the market: the first one is to customize the plastic bag of this kind of material, there is adhesive sticker seal in the mouth of the plastic bag, the article is packed into the bag manually, then seal by the adhesive sticker;
secondly, customizing the plastic bag made of the material, manually filling articles into the plastic bag, and sealing the plastic bag in a winding manner by using sealing box adhesive paper;
and thirdly, the sealing and cutting machine is used for packaging in a parallel sealing and cutting mode, the sealing and cutting mode is reflected well in the current market, but the size of the product applicable to the sealing and cutting machine is limited, for example, when the length of the product in express packaging exceeds 500mm, the existing edge sealing equipment cannot be used for packaging.
In summary, the first two packaging methods have low production efficiency and high labor cost, and are the most undesirable packaging methods for enterprises. The third packaging mode is limited by the size of the film coated by the equipment, the sealing and cutting equipment has the problem of non-universality, and the problem of limited size of the packaged product, particularly the sealing and cutting length, exists no matter how the equipment is increased. The PE and PO mixed film sealing is firmest by adopting instant heating sealing of a heating wire, and the sealing line is not wide, but the function of instant heating (commonly called cold knife sealing) sealing of the heating wire cannot be realized on an L-sealing and cutting machine and an edge sealing machine. At present, edge sealing machine express packaging equipment is also arranged on the market, but a small section of opening or infirm phenomenon exists on an edge sealing line periodically. The use requirement of the client cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to above-mentioned prior art not enough, provide a plastics express delivery bag seals with edge sealing mechanism, accomplish and seal the line and widen and firmly seal, and solve in the express packaging product length size when exceeding 500mm, the problem that current equipment for packing can not pack.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a plastics express delivery bag seals with limit mechanism, includes the frame, its characterized in that, install the limit on the frame and seal the sword, limit seal the sword axis with give the bag linear direction parallel, limit seal sword tip is equipped with the banding blade, the limit is sealed sword and is located banding blade one side and is equipped with the supplementary banding piece of installing in the frame and can carry out the banding work with the cooperation of banding blade.
By adopting the technical scheme, the operation mode of the plastic express bag (film) after being thermally cut by the edge sealing knife is thoroughly changed, the plastic express bag (film) can be pressed down by the edge sealing knife to form an included angle with the side surface of the knife when being operated along the direction of a bag to be cut, the contact width of the edge of the plastic express bag (film) and the side surface of the edge sealing knife is widened under the action of the auxiliary edge sealing block, so that the aim of widening and fixing the sealing line is fulfilled, the problem that the existing packaging equipment cannot package when the length size of a product exceeds 500mm in express packaging is solved, the technical scheme is ingenious in conception, the parts are simple in structure, the manufacturing cost is low, and the plastic express bag edge sealing device is suitable for being used in plastic bag edge sealing equipment with various specifications.
Foretell a plastics express delivery bag seals with edge sealing mechanism can further set up as: the auxiliary edge sealing block is provided with a lower runner distributed along the linear direction of the bag towards one side of the edge sealing edge, and the edge sealing edge is in clearance fit with the lower runner and extends into the lower runner for a plane with a width value.
Adopt above-mentioned technical scheme, be the plane with the setting of banding blade, compare the banding sword among the prior art, the line of sealing is widened, it is further, plastics express delivery bag (membrane) is after being opened by the banding sword heat, when effectively giving a bag direction operation, the plane of the banding blade department of banding sword is pushed down by the limit, form the contained angle with the side of limit banding sword, under the runner effect down, plastics express delivery bag (membrane) limit and limit banding sword side contact width have further been widened, thereby accomplish the line of sealing and further widen and firm purpose, it is firm to seal plastics express delivery bag (membrane) after this mechanism banding, it is difficult damaged.
Foretell a plastics express delivery bag seals with edge sealing mechanism can further set up as: the lower runner is provided with extension cambered surfaces corresponding to two sides of the edge sealing edge respectively.
Adopt above-mentioned technical scheme, the extension cambered surface mainly plays two aspects effects, and one is the cooperation banding blade widens the line width of sealing, makes to seal firmly, and its second has the cambered surface of certain camber, can not be with plastics express delivery bag (membrane) scratch.
Foretell a plastics express delivery bag seals with edge sealing mechanism can further set up as: the auxiliary edge sealing block is provided with milling grooves distributed at two ends of the lower runner along the linear direction of the effective feeding bag.
By adopting the technical scheme, the milling groove is arranged, so that garbage deposition is not easy to generate, the edge sealing is not damaged, and the appearance of the edge sealing is ensured.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
