Technical Field

[0001] The utility model relates to the technical field of bag making machines, in particular to a glue coating device for a bag making machine. Background Technique

[0002] A bag making machine is an automated mechanical device used for producing various plastic bags, paper bags or packaging bags made of other materials. Through a series of complex technological steps such as material feeding, forming, sealing, cutting, etc., this machine can quickly and efficiently produce packaging bags that meet specific specifications and requirements. Bag making machines are widely used in multiple industries such as food, medicine, chemical industry, daily necessities, etc., and are one of the key devices on the packaging production line.

[0003] Currently, most packaging bags are made of plastic films, and the bag making machine seals the plastic films through heat melting. However, plastic packaging bags have poor environmental protection. Currently, paper bags are generally used to replace plastic packaging bags. However, since paper bags cannot be formed by heat sealing during the production process, glue needs to be applied to the paper bags so that the paper bags can be pasted together to form. However, the current bag making machines have low glue coating efficiency for paper bags. Summary of the Invention

[0024] The embodiments of the present utility model disclose a glue - applying device for a bag - making machine, as Figures 1-5As shown in the figure, it includes a machine body 1. Two mutually parallel rolls of paper material 11 are placed vertically on the machine body 1. After the paper material 11 is released, it enters the machine body 1.

The two ends of the pressing frame 4 are slidably connected in the vertical direction with a bearing seat 42. A pressing roller 43 is arranged between the two bearing seats 42 along the axial length direction parallel to the rotating roller 41. The two ends of the pressing roller 43 are respectively rotatably carried on the side walls of the two bearing seats 42. Pressing cylinders 44 are fixedly installed at the two ends of the pressing frame 4 in the vertical direction. The piston rods of the pressing cylinders 44 are fixedly connected to the bearing seat 42.

A feeding synchronous belt is wrapped and connected between the driving synchronous pulley and the driven synchronous pulley 45. After the two rolls of paper material 11 are released, they respectively pass through the two pressing frames 4. When the pressing cylinder 44 drives the pressing roller 43 to move downward, the pressing roller 43 and the rotating roller 41 press the paper material 11. Then the feeding motor works to drive the rotating roller 41 to rotate, and the rotating roller 41 and the pressing roller 43 drive the paper material 11 to move forward, so as to perform feeding.

[0025] A longitudinal gluing frame 3 is arranged on the machine body 1. The longitudinal gluing frame 3 is arranged along the axial length direction parallel to the rotating roller 41. A longitudinal gluing head 31 is arranged on the longitudinal gluing frame 3. When the paper material 11 passes through the longitudinal gluing frame 3, the longitudinal gluing head 31 continuously applies glue to one side edge of the upper surface of the paper material 11. In addition, guide columns 32 are fixedly arranged along the axial length direction parallel to the rotating roller 41 on the longitudinal gluing frame 3. A mounting seat 33 is slidably connected to the guide columns 32. The longitudinal gluing head 31 is fixedly installed on the mounting seat 33.

When it is necessary to adjust the position of the longitudinal gluing head 31, the operator rotates the lead screw 34 to drive the mounting seat 33 to move along the width direction of the paper material 11, so as to conveniently adjust the position of the longitudinal gluing head 31, so as to better match the width of the paper material 11. In addition, in order to facilitate the operator to rotate the lead screw 34, an adjusting handwheel 35 is fixedly arranged at one end of the lead screw 34.

A horizontal glue application seat 23 is fixedly connected to the driving synchronous belt, and the horizontal glue applicator head 21 is provided on the horizontal glue application seat 23. When the driving motor 22 works to drive the driving synchronous pulley to rotate, the driving synchronous belt is driven to move, thereby driving the horizontal glue application seat 23 to move, driving the horizontal glue applicator head 21 to move along the width direction of the paper material 11, and thus applying glue on the paper material 11. In addition, two horizontal glue applicators 2 are provided. In this way, two layers of glue can be applied on the paper material 11 simultaneously, and the glue application efficiency is higher.

[0027] In addition, a lifting member for driving the horizontal glue applicator head 21 to lift is provided on the horizontal glue applicator 2. Specifically, the lifting member includes a lifting cylinder 24 fixedly installed on the horizontal glue application seat 23 in the vertical direction. The piston rod of the lifting cylinder 24 is fixedly connected to the horizontal glue applicator head 21. When the piston rod of the lifting cylinder 24 extends, the horizontal glue applicator head 21 is driven to lower, so as to contact the paper material 11 and apply glue on the paper material 11. In addition, a plurality of supporting rollers 25 are arranged on the horizontal glue applicator 2 along the axial length direction parallel to the rotating roller 41. Both ends of the supporting roller 25 are rotatably carried on the side walls of the horizontal glue applicator 2.

[0028] In addition, a blowing frame is provided on the machine body 1. An air pipe is fixedly installed on the blowing frame. A plurality of blowing holes are opened on the air pipe.

In addition, a protective net is fixedly installed on the blowing frame, and the air pipe is located inside the protective net. In addition, a plurality of parallel guide rollers 12 are arranged on the top of the machine body 1 along the axial length direction parallel to the rotating roller 41. One roll of paper material 11 passes through the horizontal glue application mechanism, the longitudinal glue application mechanism and the blowing frame, and the other roll of paper material 11 passes through the plurality of guide rollers 12. Through such a setting, one roll of paper material 11 is coated with glue, while the other roll of paper material 11 is not coated, and then the two paper materials 11 are bonded together.

[0029] The implementation principle of a glue - applying device for a bag - making machine in an embodiment of the present utility model is as follows: When the feeding motor operates, it drives the movement of the paper material 11 for feeding. During glue - applying, the paper material 11 passes below the longitudinal glue - applying head 31, and then the longitudinal glue - applying head 31 continuously applies glue to one side edge of the upper surface of the paper material 11. When the paper material 11 passes through the transverse glue - applying head 21, the driving motor 22 operates to drive the transverse glue - applying head 21 to move along the width direction of the paper material 11. The two transverse glue - applying heads 21 simultaneously apply two layers of glue on the width direction of the upper surface of the paper material 11, with high glue - applying efficiency. Moreover, the other side edge of the paper material 11 is not coated with glue. Thus, after the paper material 11 is made into a packaging bag, three sides are sealed and one side is open.
