Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag production, in particular to a composite device for packaging bag films. Background Art

[0002] With the rapid development of industries such as food, medicine, and daily chemicals, the requirements for packaging materials are becoming increasingly higher. Composite packaging bag films, as a packaging material that integrates multiple excellent properties such as barrier properties, drop resistance, and aesthetics, are gradually favored by the market. The composite device of packaging bag films continues to grow and develop under the impetus of market demand, technological progress, and environmental protection requirements. In the future, with further technological innovation and continuous improvement of environmental awareness, the performance and efficiency of the composite device will be further improved, and its application areas will continue to expand.

[0003] For example, a Chinese patent (publication number: CN208630003U) discloses a composite packaging bag making device. The composite packaging bag making device provided in an embodiment of the utility model includes a first film supply device, a coding device, a gluing device, a drying device, a second film supply device, a compounding device, and a bag-making device. The bag-making device is used to form the composite film into packaging bags. The composite packaging bag making device provided in an embodiment of the utility model is provided with a coding device, which sets an identification code on the inner layer of the first film. After the first film provided by the first film supply device is compounded with the second film provided by the second film supply device, the identification code on the inner layer of the first film is covered by the second film, making the code difficult to clean, thereby effectively reducing the possibility of the code or other markings being removed.

[0004] However, the composite effect of the device on the packaging bag film is not good enough. The device only realizes the composite of the film by the cooperation of the composite roller and the preheating roller. The same composite effect cannot be guaranteed for different films. Therefore, a composite device for packaging bag film is proposed to solve the above problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a composite device for packaging bag films, which has the advantage of good composite effect and solves the problem that the composite effect cannot be guaranteed when facing different films.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a composite device for packaging bag film, comprising a box body, the left side of the box body is rotatably connected to a discharge roller, the bottom of the box body is fixed with a base, and a tensioning wheel is rotatably connected between the front and rear side walls of the box body and on the side close to the discharge roller, and the inner cavity of the box body is provided with two film laminating assemblies for realizing film lamination, the film laminating assembly is located on the right side of the tensioning wheel, and two reversing wheels are rotatably connected to the bottom of the film laminating assembly through bearings between the front and rear side walls of the inner cavity of the box body and on the right side of the film laminating assembly. A hot pressing mechanism for improving the film laminating effect is provided at the bottom of the film laminating assembly, and two fixed rollers located on the left side of the hot pressing mechanism are rotatably connected through bearings on the left side of the hot pressing mechanism and located between the front and rear side walls of the inner cavity of the box body. A tightening mechanism for providing power is provided at the discharge port of the box body and on the outside of the box;

[0007] The hot pressing mechanism includes a fixed plate, a platform, a servo motor, an active rod, a driven rod and two hot pressing blocks. The fixed plate and the platform are fixed to the front and rear side walls of the box body. The fixed plate and the platform are respectively located on both sides of the packaging bag film. The top of the fixed plate is fixed to the servo motor, and the output shaft of the servo motor is fixed to the active rod. The bottom of the fixed plate is rotatably connected to the driven rod through a bearing, and the outer surfaces of the active rod and the driven rod are threadedly connected to the two hot pressing blocks.

[0008] By adopting this technical solution, the hot pressing mechanism can freely adjust the pressure, and can still ensure the composite effect when facing films of different thicknesses, further improving the composite effect of the device.

[0009] Furthermore, the platform includes a fixing seat, a driving gear and a driven gear. The driving rod and the driven rod both pass through the bottom of the fixing seat. The outer surfaces of the driving rod and the driven rod are fixed to the driving gear and the driven gear respectively.

[0010] By adopting this technical solution, the provision of a driving gear and a driven gear can ensure that the movement of the driving rod and the driven rod are performed simultaneously, thereby further improving the operating efficiency of the device.

[0011] Furthermore, threaded connection blocks are fixed at both ends of the two hot pressing blocks, and a threaded hole is provided in each of the threaded connection blocks.

[0012] By adopting this technical solution, the two threaded connection blocks can simultaneously limit the hot pressing block, preventing the hot pressing block from rotating and ensuring that the hot pressing block can move up and down smoothly.

[0013] Furthermore, two external threads with opposite rotation directions are fixed on the outer surfaces of the active rod and the driven rod, and the external threads at the same horizontal position of the active rod and the driven rod have opposite rotation directions.

[0014] By adopting this technical solution, the two threaded strips with opposite rotation directions can ensure that under the same rotation direction, the two hot pressing blocks can still be prompted to move relative to or away from each other.

[0015] Furthermore, an internal thread strip is fixed in each of the threaded holes, and the internal thread strip is adapted to the external thread strip.

[0016] By adopting this technical solution, the use of the inner thread strip and the outer thread strip in coordination with each other can greatly improve the operating precision of the device, further improve the precise control of the pressure, thereby ensuring high efficiency and high quality of the composite.

[0017] Furthermore, the driving gear and the driven gear are meshed with each other, and both the driving gear and the driven gear are located on the lower side of the fixing seat.

[0018] By adopting this technical solution, the mutual engagement of the driving gear and the driven gear can enable power to be transmitted to the active rod and the driven rod at the same time, thereby ensuring the smooth operation of the two hot pressing blocks.

[0019] Furthermore, each of the laminating components includes a film rolling wheel and a laminating wheel. The two laminating components are respectively located on the upper and lower sides of the packaging bag film. Each of the film rolling wheel and the laminating wheel is rotatably connected to the front and rear side walls of the inner cavity of the box body through bearings, and each of the laminating wheels is tightly attached to the packaging bag film.

[0020] By adopting this technical solution, the two laminating wheels can laminarize both sides of the packaging bag at the same time, which can effectively improve the laminating efficiency and further improve the overall efficiency of the packaging bag film composite.

[0021] Furthermore, the tightening mechanism includes a rear partition, a front partition, a drive motor and a winding roller. The rear partition and the front partition are both fixed to the right side wall of the box. The output shaft of the drive motor passes through the rear partition and is fixed to the winding roller. The side of the winding roller away from the drive motor is rotatably connected to the front partition through a bearing.

[0022] By adopting this technical solution, the drive motor can continuously output power, prompting the winding roller to continuously rotate, further ensuring the continuous movement of the packaging bag.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The packaging bag film composite device starts the tightening mechanism and the hot pressing mechanism. The continuous operation of the tightening mechanism will drive the packaging bag to move continuously. During the continuous movement of the packaging bag, it will drive the two film covering components to operate, so that the inner film and the outer mold are simultaneously pasted to both sides of the packaging bag. At the same time, the hot pressing mechanism is adjusted to achieve pressure adjustment during film composite, so as to ensure that the same composite effect can be achieved when facing different films, and continuous heating is carried out. When the film composite is completed, the tightening mechanism will continue to roll up the composited packaging bag to facilitate the staff to take it. The device can freely adjust the composite pressure, and under the simultaneous action of pressure and heat, further improve the composite effect of the packaging bag film.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] It can be known that each laminating component 5 includes a film rolling wheel 501 and a laminating wheel 502. The two laminating components 5 are respectively located on the upper and lower sides of the packaging bag film. Each film rolling wheel 501 and laminating wheel 502 are rotatably connected to the front and rear side walls of the inner cavity of the box body 1 through bearings. Each laminating wheel 502 is tightly attached to the packaging bag film. The two laminating wheels 502 can laminarize the packaging bag at the same time. The packaging bag will pull the laminating wheel 502 during movement, prompting the laminating wheel 502 to rotate. The rotation of the laminating wheel 502 will further pull the film, prompting the film rolling wheel 501 to rotate. Through the mutual cooperation of the film rolling wheel 501 and the laminating wheel 502, the operating efficiency of the device can be effectively improved.

[0033] It should be noted that by laminating the packaging bag with two laminating assemblies 5 at the same time and then performing hot pressing with two hot pressing blocks 806 at the same time, the laminating efficiency of the packaging bag film can be further improved and the laminating quality of the packaging bag film can be ensured.

[0034] Please refer again Figure 1 and Figures 2 to 4 In order to improve the composite effect, the hot pressing mechanism 8 in this embodiment includes a fixed plate 801, a platform 802, a servo motor 803, an active rod 804, a driven rod 805 and two hot pressing blocks 806. The fixed plate 801 and the platform 802 are fixed to the front and rear side walls of the box body 1. The fixed plate 801 and the platform 802 are respectively located on both sides of the packaging bag film. The top of the fixed plate 801 is fixed to the servo motor 803, and the output shaft of the servo motor 803 is fixed to the active rod 804. The bottom of the fixed plate 801 is rotatably connected to the driven rod 805 through a bearing. The outer surfaces of the active rod 804 and the driven rod 805 are both threadedly connected to the two hot pressing blocks 806.

[0035] In addition, the platform 802 includes a fixed seat 8021, a driving gear 8022 and a driven gear 8023. The active rod 804 and the driven rod 805 both extend to the bottom of the fixed seat 8021. The outer surfaces of the active rod 804 and the driven rod 805 are fixed to the driving gear 8022 and the driven gear 8023 respectively. The fixed seat 8021 and the fixed plate 801 can ensure that the hot pressing mechanism 8 as a whole has sufficient supporting force, and at the same time ensure that the supporting force is continuous and reliable.

[0036] In addition, the driving gear 8022 and the driven gear 8023 are engaged with each other, and the driving gear 8022 and the driven gear 8023 are both located on the lower side of the fixed seat 8021. Setting both the driving gear 8022 and the driven gear 8023 below the fixed seat 8021 can reserve enough space for the hot pressing block 806, thereby improving the versatility of the hot pressing mechanism 8.

[0037] It can be known that two external threads with opposite rotation directions are fixed on the outer surface of the active rod 804 and the driven rod 805. The external threads at the same horizontal position of the active rod 804 and the driven rod 805 have opposite rotation directions. Threaded connection blocks are fixed at both ends of the two hot pressing blocks 806. A threaded hole is provided in each threaded connection block. An internal threaded strip is fixed in each threaded hole. The internal threaded strip is adapted to the external threaded strip. Since the active gear 8022 and the driven gear 8023 are externally meshed once, the rotation directions after meshing are opposite. In order to ensure the smooth operation of the two hot pressing blocks 806, it is necessary to set the external threads of the active rod 804 and the driven rod 805 to have opposite rotation directions.

[0038] It should be further explained that the tightening mechanism 9 includes a rear partition 901, a front partition 902, a drive motor 903 and a winding roller 904. The rear partition 901 and the front partition 902 are both fixed to the right side wall of the box body 1. The output shaft of the drive motor 903 passes through the rear partition 901 and is fixed to the winding roller 904. The side of the winding roller 904 away from the drive motor 903 is rotatably connected to the front partition 902 through a bearing. The power of the drive motor 903 will prompt the winding roller 904 to tighten synchronously. During the rotation of the winding roller 904, the packaging bag will be continuously pulled, prompting the packaging bag to continue to move, thereby ensuring the smooth operation of the composite device.

[0039] In this embodiment, the control servo motor 803 can control the relative positions of the two hot pressing blocks 806. When encountering films of different thicknesses, the relative positions of the two hot pressing blocks 806 can be adjusted to ensure that each film has the same composite effect.

[0040] It can be understood that through the mutual cooperation between the discharge roller 2 and the winding roller 904, the packaging bags can be continuously transported into the device and the packaging bags can be provided with moving power. Through the mutual cooperation between the laminating component 5 and the hot pressing mechanism 8, the composite efficiency and composite quality of the packaging bag film can be effectively improved.

[0041] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The power supply provided by the battery is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0042] The working principle of the above embodiment is:

[0043] Before use, start the servo motor 803, which will cause the active rod 804 to rotate. The power is transmitted through the active gear 8022 and the driven gear 8023, further driving the driven rod 805 to rotate, thereby adjusting the relative distance between the two hot pressing blocks 806. During the operation of the device, the driving motor 903 will drive the winding roller 904 to rotate continuously, thereby continuously winding the packaging bag and causing the packaging bag to move smoothly. The cooperation between the unwinding roller 2 and the winding roller 904 can ensure the continuous and efficient operation of the device. When the packaging bag passes through the two laminating wheels 502, the friction force will cause the two laminating wheels 502 to rotate. 02 rotates and sticks the film on the laminating wheel 502 to the packaging bag. At the same time, the rotation of the laminating wheel 502 will pull the film, further prompting the film rolling wheel 501 to rotate, ensuring the continuous lamination. Then the packaging bag with the initial lamination will pass through two hot pressing blocks 806. The two hot pressing blocks 806 continue to squeeze and heat the packaging bag film, prompting the packaging bag film to complete the compounding. After the compounding is completed, it is collected by the winding roller 904 for the convenience of staff to take. The device can freely adjust the pressure during compounding, and can ensure the same compounding effect when facing films of different thicknesses, and further improve the compounding effect with its own heating.
