Description
Technical field
The present invention relates to packaging bag manufacturing equipment field, particularly a kind of double-bending sealing mechanism for heat-sealed bag.
Background technology
At present, hot-seal paper bag is extensively employed because it uses the convenience of operation, but at some higher-end businesses, time such as packing the material needing lucifuge, the deficiency on hot-seal paper bag sealing device and sealing mode just comes out.As shown in Figure 1, traditional hot-seal paper bag structure is as follows: one or more layers paper is rolled into tubular to form a bag body 1.In one end of bag body, back side paper 2 grows about three centimetres than front paper, is coated with the first hot melt glue 3 in the region that this grows.Symmetrical contrary, at the other end of bag body, front paper grows about three centimetres than back side paper, equally also smears the second hot melt glue 6 growing part, material from front paper and back side paper point staggered positions 5 points stagger laggard enter the inside of bag body 1.As shown in Figure 2, in one end of bag body 1, back side paper 2 grows about three centimetres than front paper, grow part be coated with the first hot melt glue 3, material staggers from front paper and back side paper point staggered positions 5 points, material is the inside entering bag body 1 from this position, hot-seal is in the position of hot-seal line position 4, as shown in Figure 3, on hot-seal angle bender, position folding back facial tissue along hot-seal line position 4 is opened and is grown part than front paper, after heating, first hot melt glue 3 just bonds back side paper 2 and front paper two parts to have got up, can clearly find out, the inside that bag body 1 is led in space can be left at front paper and back side paper point staggered positions 5, when filling be the material needing lucifuge time, light will likely from then on space enter, cause packing unsuccessfully.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of double-bending sealing mechanism for heat-sealed bag, and heat-sealed bag sack can doublely fold by it in bag making process, utilizes the characteristic that can not turn of light, thus reaches the object of the rear lucifuge completely of packaging.
For solveing the technical problem, the invention provides a kind of double-bending sealing mechanism for heat-sealed bag, it is characterized in that, it comprises framework, gear, synchronous pulley, upper axle, lower shaft, send a bag frame, electric appliance control box, hot melt glue gumming mechanism, first bending plate, second bending plate, Timing Belt, closing bag frame, in one end of framework, axle is installed, just below lower shaft is installed at upper axle, in one end of upper axle and lower shaft, gear is installed, upper axle and lower shaft are parallel-laid into and over the ground synchronous pulley are installed, synchronous pulley is provided with four Timing Belts, be separately installed with at the two ends of framework and send bag frame and closing bag frame, at framework and send the side of bag frame to be also provided with electric appliance control box, hot melt glue gumming mechanism, first bending plate and the second bending plate are fixed on the side of framework.
Preferably, described first bending plate and the second bending plate all comprise U-shaped outside plate and central layer, and central layer is arranged in U-shaped outside plate.
Positive progressive effect of the present invention is: heat-sealed bag sack can doublely fold by double-bending sealing mechanism for heat-sealed bag of the present invention in bag making process, utilizes the characteristic that can not turn of light, thus reaches the object of the rear lucifuge completely of packaging.

Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the present invention to be described.
As shown in Figure 4, double-bending sealing mechanism for heat-sealed bag of the present invention comprises framework 11, gear 12, synchronous pulley 13, upper axle 14, lower shaft 15, send bag frame 17, electric appliance control box 18, hot melt glue gumming mechanism 20, first bending plate 21, second bending plate 22, Timing Belt 23, closing bag frame 24, in one end of framework 11, axle 14 is installed, at upper axle 14, lower shaft 15 is installed just below, the gear 12 of a pair drive shaft turns is installed in one end of upper axle 14 and lower shaft 15, upper axle 14 and lower shaft 15 are parallel-laid into synchronous pulley 13 is installed over the ground, synchronous pulley 13 is provided with four Timing Belts 23, after bag cylinder 16 is pushed into this double-bending sealing mechanism for heat-sealed bag, the Timing Belt 23 of paired work tightly will clamp the two ends of bag cylinder 16, but expose the position being coated with hot melt glue and the position needing bending.Be separately installed with at the two ends of framework 11 and send bag frame 17 and closing bag frame 24, at framework 11 with send the side of bag frame 17 to be also provided with electric appliance control box 18, hot melt glue gumming mechanism 20, first bending plate 21 and the second bending plate 22 are fixed on the side of framework 11.As shown in Figure 5, first bending plate 21 and the second bending plate 22 all comprise U-shaped outside plate 27 and central layer 29, the central layer 29 of winding type is installed in U-shaped outside plate 27, central layer 29 and U-shaped outside plate 27 between have gap to hold bag cylinder 16 oral area pass through, second bending plate 21 is identical with the structure of the first bending plate 22, gap just between the central layer 29 of the second bending plate and U-shaped outside plate 27 wants large, and the oral area that can hold bending bag cylinder 16 once passes through.
After bag cylinder 16 is pushed into this double-bending sealing mechanism for heat-sealed bag, paired Timing Belt 23 tightly embraces the two ends of clamping bag cylinder 16, but exposes the position being coated with hot melt glue and the position needing bending.Electric appliance control box 18 controls motor driven gear 12 and rotates, gear 12 drives upper axle 14 and lower shaft 15 to rotate, upper axle 14 and lower shaft 15 rotate and drive synchronous pulley 13 mounted thereto to rotate, the rotation of synchronous pulley 13 has just driven the cycle rotation of Timing Belt 23, bag cylinder 16 is embraced to clip successively and is undertaken smearing hot melt glue action by hot melt glue gumming mechanism 20, afterwards, enter the first bending plate 21 again, when entering the first bending plate 21, as shown in Figure 5, the oral area of bag cylinder 16 enters U-shaped outside plate 27 and within it installs at import 26 place of U-shaped outside plate 27 gap of the central layer 29 of winding type along bag nozzle portion sense of motion 30 (direction of arrow), U-shaped outside plate 27 turns up the oral area of bag cylinder 16 from bottom, central layer 29 pushes down bending line 31 from top, the part in the bag nozzle portion be not held down just is bent 180 degree gradually, walk out from the outlet 28 of U-shaped outside plate 27, again enter the second bending plate 22, carry out second time bending, by continuous action above, the two ends of heat-sealed bag have been bent twice continuously, obtain finished product 25.Bending action process is shown in Fig. 6, double-bending sealing mechanism for heat-sealed bag of the present invention grows part along hot-seal line position 4 upwards bending back side paper 2 than the paper in front, complete first time bending, then the secondary bending mechanism of double-bending sealing mechanism for heat-sealed bag can upwards bag folding mouth again, complete twice bending, at this moment, first hot melt glue 3 grows part by the back side paper 2 bent, be bonded together with front paper, as can be seen from Figure 6, at this moment, centre is involved in towards the front paper of bag body 1 inside and back side paper point staggered positions 5, so just close sack completely, reach the object of the material that keeps in Dark Place completely, there is this double-bending sealing mechanism for heat-sealed bag, expand the range of use of hot-seal paper bag further.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that these are only casehistorys, under the prerequisite not deviating from principle of the present invention and essence, various changes or modifications can be made to these embodiments.Therefore, protection scope of the present invention is defined by the appended claims.
