Abstract
The utility model relates to a plastic packaging machine, in particular to an improved cooling device of a bag making machine, belonging to the field of the packaging machine. The improved cooling device comprises a cooling cutter and a cushion plate, wherein the cooling cutter and the cushion plate correspond to each other from the upper part to the lower part; the cooling cutter is hollow; two sides of the cutter body are provided with a water inlet pipe and a water outlet pipe; and after improvement, the bottom part of the cutter body is provided with a plurality of parallel through grooves. The cooling device of the bag making machine utilizes the characteristics of thermostable shrinkage and restorable elastic deformation of plastics, is added with a plurality of parallel through grooves with intervals on the basis of the original cooling cutter, carries out prestretching to material films of the packaging bag in the cooling procedure, solves the corrugation phenomenon of the front pattern position corresponding to middle sealing of the packaging bag product after the middle sealing made bag is formed, stabilizes the product quality and improves production efficiency.
Description
Technical field
The utility model relates to a kind of plastics package machinery, is specially a kind of improved bag-making machine cooler, belongs to packing machinery technology.
Background technology
Plastic bag making machine is a kind of machinery commonly used in the plastics package machinery, and it walks to expect that by batch (-type) mechanism drives the material film and finishes the bag operation by scalding cutter, cooling knife, cutting knife respectively; Walk to expect mechanism's intermitten, can realize automated production.In material film heat seal operation, it is higher to scald the cutter temperature, expects that then film cools off via cooling knife, after the cutting knife cutting, and a plurality of finished bags packaging and warehousing that overlaps.
In the practical application, middle envelope bag product quantity in flexible packing products is very big, be representative products with composite plastic films such as BOPP/PE, NY/PE, BOPP/CPP again wherein, in the production process, after the middle envelope heat seal bag to the packaging bag back, the front pattern of middle envelope position correspondence is because the influence of envelope position high temperature in being subjected to, shrinkage can take place after the cooling in composite membrane naturally, produce gauffer, influenced the outward appearance of product, severe patient may be rejected by the client.In order to change above-mentioned defective, thermoplasticity principle according to composite membrane (is that the forfeiture of composite membrane temperature is slow, the product ST is long, the shrinkage factor height, otherwise shrinkage factor is low), in the actual production, in order to reduce the product shrinkage factor, usually by reducing speed of production, reducing cooling water temperature, increase cooling rate to reach, shorten ST, reduce the product shrinkage factor.Adopt and reduce cooling water temperature, DeGrain and very difficult the realization; And the reduction speed of production has directly influenced output, has increased cost; Take the product that will process, per 20~50 1 fully hang after the cooling packing again spreading out, not only take and hang the space in a large number, and packaging bag is contaminated easily in the process of hanging.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of good cooling results, bag-making machine cooler that production efficiency is high is provided.
The alleged problem of the utility model solves with following technical proposals:
A kind of bag-making machine cooler comprises cooling knife, backing plate, and described cooling knife and backing plate are corresponding up and down, cooling knife hollow, and the cutter hub both sides are provided with water inlet pipe and outlet pipe, after the improvement, in the cutter hub bottom a plurality of parallel conduction through concave trough are set.
Above-mentioned bag-making machine cooler is provided with the cushion block corresponding with groove on the described backing plate.
Above-mentioned bag-making machine cooler, described depth of groove 3~50mm, width 10~100mm, spacing 5~100mm.
Above-mentioned bag-making machine cooler, the high 0~25mm of described cushion block, wide 5~100mm.
Above-mentioned bag-making machine cooler, the groove quantity of described cutter hub bottom is set to 3~7.
The utility model utilizes the thermally-stabilised contraction and the recoverable elastic deformation character of plastics, on original cooling knife basis, increased the conduction through concave trough that a plurality of parallel interval are provided with, in refrigerating work procedure, packing Bag Material film is carried out prestretched, solved the gauffer phenomenon at pattern place, the corresponding front of the middle envelope of packaging bag product after the moulding of middle envelope bag, stablize product quality, improved production efficiency.
The utility model is provided with corresponding cushion block on the backing plate corresponding with the cooling knife groove, under the support of cushion block, packing Bag Material film can obtain better prestretched.
The utility model is mainly used in thermoplastic property and seals the bag product in the composite plastic films such as BOPP/PE, NY/PE, BOPP/CPP preferably, has optimized operating procedure, has stablized product quality, and production efficiency is greatly improved.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 right view.
Each label is expressed as follows among the figure: 1. cooling knife; 2. backing plate; 3. water inlet pipe; 4. outlet pipe; 5. groove; 6. cushion block; 7. composite membrane.
The specific embodiment
As shown in Figure 1, a kind of bag-making machine cooler, comprise corresponding up and down cooling knife 1 and backing plate 2, cooling knife hollow, cutter hub both sides are provided with water inlet pipe 3 and outlet pipe 4, after the improvement, parallel interval is provided with a plurality of straight-through grooves 5 in the cutter hub bottom, depth of groove 3~50mm, width 10~100mm, spacing 5~100mm.The cushion block 6 corresponding with groove, the high 0~25mm of cushion block, wide 5~100mm are set on backing plate.In the production process, cooling water flows into from the left side water inlet pipe, flows out from the right side outlet pipe; Composite membrane 7 is walking to expect that mechanism moves under driving from left to right, and is consistent with the cooling water water (flow) direction, improved cooling effectiveness.The groove quantity of cutter hub bottom is set to 3~7, and groove location is arranged on right side, cutter hub bottom, and is better to the prestretched effect of composite membrane, better stabilized product quality.
After the utility model uses, but stabilized product quality guarantees the whole corrugationless of packaging bag, and product roll off the production line the back directly vanning seal up for safekeeping, saved the airing operation, saved the time, order of classes or grades at school production efficiency obtains raising in various degree.Actual test performance sees Table 1.
