Technical Field

[0001] This utility model relates to the technical field of high-efficiency devices for composite three-layer film packaging bags, and in particular to a high-efficiency device for composite three-layer film packaging bags. Background Technology

[0002] Bags are flexible or semi-rigid containers used to contain, protect, and transport goods. They are widely used in daily life and industrial production. Their core functions include protecting goods from physical damage, chemical changes, or biological harm, while facilitating storage, transportation, and sales. There are two main types of efficient devices for composite three-layer film packaging bags: three-layer co-extrusion blown film machines and three-layer composite packaging bag laminating machines.

[0003] An existing high-efficiency device for composite three-layer film packaging bags requires drying the composite film using an oven. Due to the large temperature difference inside the oven, the temperature is higher closer to the film, which can easily cause localized high temperatures in the film, thus affecting the lamination effect. Therefore, a high-efficiency device for composite three-layer film packaging bags is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient device for composite three-layer film packaging bags.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency device for composite three-layer film packaging bags, comprising a mounting frame, wherein a first discharge roller, a second discharge roller and a third discharge roller are installed inside the mounting frame, an adhesive coating roller assembly is installed inside the mounting frame, a fixing frame is fixedly connected to the inner bottom of the mounting frame, and a composite pressure roller is installed inside the fixing frame, a drying assembly is provided at the side end of the composite pressure roller, and a winding roller is provided at the side end of the drying assembly, and the winding roller is rotatably connected to the interior of the mounting frame;

[0006] The drying assembly includes a drying chamber, with grooves provided at the top and bottom of the chamber. A first reciprocating screw and a second reciprocating screw are rotatably connected inside the two grooves, respectively. Connecting blocks are threaded onto the outside of both the first and second reciprocating screws. Circulating fans are fixedly connected to the ends of both connecting blocks, and the two circulating fans are symmetrically distributed.

[0007] Furthermore: a first synchronous pulley is fixedly connected to the end of the first reciprocating lead screw, a second synchronous pulley is fixedly connected to the end of the second reciprocating lead screw, and synchronous belts are movably connected to the outside of both the first and second synchronous pulleys.

[0008] Furthermore: the end of the second reciprocating screw is fixedly connected to the output end of the second motor, the front end face of the drying box is fixedly connected to a support plate, and the second motor is located on top of the support plate.

[0009] Furthermore, the coating roller assembly includes a first roller shaft and a second roller shaft. A first gear is fixedly connected to the circumferential surface of the first roller shaft, and a second gear is fixedly connected to the circumferential surface of the second roller shaft. The first gear and the second gear are externally meshed. A first motor is fixedly connected to the end of the first roller shaft.

[0010] Furthermore: the end of the take-up roller is fixedly connected to the output end of a third motor, the rear end face of the mounting frame is fixedly connected to a mounting plate, and the third motor is located on top of the mounting plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. Compared with the prior art, this high-efficiency device for composite three-layer film packaging bags, by setting up a first reciprocating screw, a second reciprocating screw, a connecting block, and a circulating fan, allows the first and second reciprocating screws to rotate synchronously during use. This causes the circulating fans on both sides to move from the sides towards the middle and then from the middle back to the sides, thereby adjusting the position of the circulating fans. The circulating fans disperse the high-temperature airflow inside the drying chamber, making the temperature distribution inside the drying chamber more uniform. This facilitates the drying of the composite three-layer film, improves the uniformity of film drying, and thus enhances the efficiency of film packaging bag lamination.

[0014] 2. Compared with the prior art, this high-efficiency device for composite three-layer film packaging bags, by setting a first gear and a second gear, when the device is in use, the first motor is started to drive the first roller shaft to rotate, thereby driving the second gear to rotate, and then driving the second roller shaft to rotate synchronously. Then, the glue coating roller is used to coat the two sides of the outer film of the second discharge roller, thereby cooperating with the upper and lower films to composite the three-layer film. This is beneficial to improve the convenience of film glue coating and facilitates the stability of the three-layer film connection. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-6 The present invention provides a high-efficiency device for composite three-layer film packaging bags: including a mounting frame 1, a first discharge roller 2, a second discharge roller 3 and a third discharge roller 4 installed inside the mounting frame 1, an adhesive coating roller assembly 8 installed inside the mounting frame 1, a fixing frame 9 fixedly connected to the inner bottom of the mounting frame 1, and a composite pressure roller 10 installed inside the fixing frame 9. A drying assembly 11 is provided on the side end of the composite pressure roller 10, and a winding roller 12 is provided on the side end of the drying assembly 11. The winding roller 12 is rotatably connected to the inside of the mounting frame 1.

[0025] The drying assembly 11 includes a drying chamber 1101. The top and bottom of the drying chamber 1101 are provided with sliding grooves 1102. The interior of the two sliding grooves 1102 is rotatably connected to a first reciprocating screw 1103 and a second reciprocating screw 1106, respectively. The exterior of the first reciprocating screw 1103 and the second reciprocating screw 1106 are threadedly connected to connecting blocks 1104. The ends of the two connecting blocks 1104 are fixedly connected to circulating fans 1105, and the two circulating fans 1105 are symmetrically distributed. When the device is in use, the first reciprocating screw 1103 and the second reciprocating screw 1106 rotate synchronously, causing the circulating fans 1105 on both sides to move from the sides to the middle, and then from the middle to the sides, thereby adjusting the position of the circulating fans 1105. The circulating fans 1105 disperse the high-temperature airflow inside the drying chamber 1101 into the interior of the drying chamber 1101, making the temperature inside the drying chamber 1101 more uniform. This facilitates the drying of the composite three-layer film, improves the uniformity of the composite film drying, and thus improves the efficiency of film packaging bag lamination.

[0026] A first synchronous pulley 1107 is fixedly connected to the end of the first reciprocating lead screw 1103, and a second synchronous pulley 1108 is fixedly connected to the end of the second reciprocating lead screw 1106. Both the first synchronous pulley 1107 and the second synchronous pulley 1108 are movably connected to a synchronous belt 1109. The first synchronous pulley 1107 and the second synchronous pulley 1108, in conjunction with the synchronous belt 1109, facilitate the synchronous rotation of the first reciprocating lead screw 1103 and the second reciprocating lead screw 1106.

[0027] The output end of the second motor 1110 is fixedly connected to the end of the second reciprocating lead screw 1106. A support plate is fixedly connected to the front end face of the drying chamber 1101, and the second motor 1110 is located on top of the support plate. The support plate is used to limit the installation of the second motor 1110, thereby providing a power source for the second reciprocating lead screw 1106 through the second motor 1110.

[0028] The coating roller assembly 8 includes a first roller shaft 801 and a second roller shaft 802. A first gear 803 is fixedly connected to the circumferential surface of the first roller shaft 801, and a second gear 804 is fixedly connected to the circumferential surface of the second roller shaft 802. The first gear 803 and the second gear 804 are externally meshed. A first motor 805 is fixedly connected to the end of the first roller shaft 801. The coating roller assembly 8 facilitates double-sided coating of the film output from the second discharge roller 3 in the middle section, thereby improving the three-layer film lamination.

[0029] The output end of a third motor 13 is fixedly connected to the end of the take-up roller 12, and a mounting plate is fixedly connected to the rear end face of the mounting frame 1, with the third motor 13 located at the top of the mounting plate. The mounting plate is used to install and limit the third motor 13, thereby driving the take-up roller 12 to wind up the composite three-layer film.

[0030] The inner wall of the mounting frame 1 is rotatably connected to a first guide roller 5, a second guide roller 6, and a third guide roller 7, with the third guide roller 7 located between the first guide roller 5 and the second guide roller 6. The first guide roller 5 guides the upper film and moves it towards the composite pressure roller 10. The second guide roller 6 guides the lower film and moves it towards the composite pressure roller 10. The third guide roller 7 guides the middle film. The middle film is coated with adhesive by the adhesive roller assembly 8 and moves towards the composite pressure roller 10. After being pressed by the composite pressure roller 10, a three-layer film is formed. The composite pressure roller 10 has two sets of synchronous pulleys and a synchronous belt on the outside of the roller shaft on the back of the mounting frame 1. Two meshing gears are installed on the outside of the roller shaft. A servo motor drives one of the roller shafts to rotate, which in turn drives the upper pressure roller to rotate counterclockwise and the lower pressure roller to rotate clockwise, thereby pressing and transporting the film.

[0031] Working principle: When the device is in use, the first guide roller 5 guides the upper film and moves it to the composite pressure roller 10. The second guide roller 6 guides the lower film and moves it to the composite pressure roller 10. The third guide roller 7 guides the middle film. The middle film is coated with glue by the glue coating roller assembly 8 and moves to the composite pressure roller 10. After being pressed by the composite pressure roller 10, a three-layer film is formed. After being dried by the drying assembly 11, it is wound up by the winding roller 12.
