Technical Field

[0001] This utility model relates to the field of drying technology in packaging bag production, specifically a drying device for a packaging bag printing machine. Background Technology

[0002] In packaging bag printing production, the printed ink needs to dry quickly to avoid smudging and ensure the integrity of the pattern. Drying equipment is an indispensable accessory for printing presses. Currently, most drying equipment used in the industry employs a single-sided hot air jet structure, which can only dry one side of the packaging bag.

[0003] Since packaging bags are mostly double-sided printed or have composite layers, single-sided drying can easily lead to insufficient drying of the ink on the unheated side, requiring manual or mechanical turning for secondary drying, which prolongs the drying cycle, reduces the throughput per unit time, and affects the drying efficiency of the printed packaging bags. Therefore, we need to propose a drying device for packaging bag printing machines. Utility Model Content

[0004] The purpose of this utility model is to provide a drying device for a packaging bag printing machine, so as to solve the problem mentioned in the background art that when drying ink on double-sided printed packaging bags, only one side of the packaging bag can be dried at a time, and the packaging bag needs to be turned over and dried a second time, which prolongs the drying cycle of the packaging bag and reduces the processing volume per unit time, thus affecting the drying efficiency of the printed packaging bag.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drying device for a packaging bag printing machine includes: a housing having a conveying channel inside for conveying packaging bags, wherein the conveying channel is provided with a plurality of first conveying rollers for guiding the packaging bags; a fixed frame and a winding mechanism mounted on the fixed frame for winding the packaging bags; and a drying mechanism for drying the packaging bags entering the housing with hot air, which is mounted at the end of the housing.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A drying device for a packaging bag printing machine includes: a housing 1, which has a conveying channel 2 for conveying packaging bags inside, and a plurality of first conveying rollers 3 for guiding packaging bags inside the conveying channel 2; a fixed frame 12, and a winding mechanism installed on the fixed frame 12 for winding the packaging bags; and a drying mechanism 9 for drying the packaging bags entering the housing 1 with hot air, which is installed at the end of the housing 1.

[0025] In an optional embodiment: such as Figure 4 As shown, the winding mechanism includes a drive motor 14, a take-up roller 15, and a pressing seat 10. The drive motor 14 is fixedly installed at the bottom of the fixed frame 12. The output shaft of the drive motor 14 is fixedly connected to the lower end of the take-up roller 15 through a coupling. The pressing seat 10 is threaded onto the take-up roller 15.

[0026] It should be noted that a receiving tray can be installed on the receiving roller 15. By threading the clamping seat 10 onto the receiving roller 15, the receiving tray can be fixed. After the receiving tray is fixed, one end of the packaging bag can be fixed on the receiving tray. The receiving roller 15 is driven to rotate by the drive motor 14, so that the packaging bag can be rolled up on the receiving tray.

[0027] In an optional embodiment: such as Figures 1 to 2As shown, the box 1 is U-shaped, and the top and both sides of the box 1 are open.

[0028] It should be noted that the opening at the top of the box 1 allows the packaging bag to be installed inside the box 1. One opening on the side of the box 1 is used as the inlet, and the other opening is used as the outlet. When the winding mechanism winds the packaging bag, the packaging bag can enter through the inlet and exit through the outlet. At the same time, the hot air discharged by the drying mechanism 9 can exit through the outlet along the conveying channel 2. This enables continuous drying of the packaging bag, reduces the manpower and equipment investment in intermediate links, lowers production costs, and eliminates the need for manual or mechanical turning for secondary processing. This significantly shortens the drying cycle, increases the throughput per unit time, and improves the drying efficiency of the packaging bag.

[0029] In an optional embodiment: such as Figure 1 As shown, it also includes a base plate, and the box body 1 and the fixing frame 12 are both fixedly installed on the top of the box body 1.

[0030] In an optional embodiment: such as Figure 3 As shown, the drying mechanism 9 includes a heating box 901, a blower 902, an electric heating wire 903, a conveying pipe 904, and a baffle shell 905. The heating box 901 and the blower 902 are both fixedly installed on the top of the base plate. The air outlet of the blower 902 is connected to the heating box 901. The electric heating wire 903 is installed inside the heating box 901. There are two sets of conveying pipes 904 and two sets of baffle shells 905. The two sets of baffle shells 905 are fixedly installed on one side of the box body 1. A clearance passage is left between the two sets of baffle shells 905. The two sets of conveying pipes 904 are symmetrically connected to the side of the heating box 901. The two sets of conveying pipes 904 are respectively located in the two sets of baffle shells 905. A protective mesh plate 906 is installed inside the baffle shell 905.

[0031] It should be noted that the heating box 901, blower 902, electric heating wire 903, conveying pipe 904 and baffle shell 905 work together to deliver hot air into the conveying channel 2, so that the hot air can be conveyed along the conveying channel 2. The mesh plate 906 provides good protection, preventing foreign objects from entering the conveying channel, and does not affect the flow of hot air.

[0032] In an optional embodiment: such as Figure 5 As shown, a support block 11 is fixedly connected to the first conveying roller 3.

[0033] It should be noted that the support block 11 is made of elastic material, which not only prevents it from falling but also avoids causing hard compression to the packaging bag.

[0034] In an optional embodiment: such as Figure 4 As shown, it also includes two sets of second conveying rollers 13, both of which are movably rotated on the fixed frame 12.

[0035] It should be noted that the two sets of second conveyor rollers 13 serve to limit the movement of the packaging bags during transport, thereby improving the stability of the packaging bags during transport and preventing the packaging bags from contacting the windshield shell 905.

[0036] In an optional embodiment: such as Figure 1 As shown, it also includes a bracket 4 fixedly installed at the bottom top. A cylinder 5 is fixedly installed at the top of the bracket 4. A lifting plate 6 is fixedly installed at the telescopic end of the cylinder 5. A sealing top plate 7 adapted to the shape of the box body 1 is fixedly installed at the bottom of the lifting plate 6. A sealing gasket 8 for sealing the top opening of the box body 1 is provided at the bottom of the sealing top plate 7.

[0037] It should be noted that the cylinder 5, the lifting plate 6 and the sealing top plate 7 work together to seal the opening at the top of the box 1, preventing hot air from leaking out and ensuring that hot air can only be transported through the conveying channel 2.

[0038] The usage process of this utility model is as follows: First, a receiving tray can be installed on the receiving roller 15, and the pressing seat 10 can be installed on the receiving roller 15 to fix the receiving tray. After the packaging bag passes through the clearance channel left between the two sets of second conveying rollers 13 and between the two sets of windproof shells 905, the packaging bag passes through the conveying channel 2 so that the packaging bag can be attached to multiple sets of first conveying rollers 3 and guided by multiple sets of first conveying rollers 3.

[0039] After the packaging bag passes through the conveyor channel 2, one end of the packaging bag is fixed on the receiving tray. The cylinder 5 is started, and the telescopic end pushes the lifting plate 6, so that the lifting plate 6 moves the sealing top plate 7 close to the opening at the top of the box 1 to seal the top of the box 1.

[0040] The drive motor 14 is started, and the output shaft of the drive motor 14 rotates to drive the receiving roller 15 to rotate. As the receiving roller 15 rotates, it rolls up the packaging bag. At the same time, the blower 902 and the electric heating wire 903 are started. The blower 902 delivers the extracted air to the heating box 901. After the extracted air is heated by the electric heating wire 903, it is delivered to the windproof shell 905 through the conveying pipe 904. The hot air delivered to the windproof shell 905 enters the conveying channel 2 through the mesh plate 906. The hot air can flow along the conveying channel 2. When the hot air is conveyed along the conveying channel 2, the conveyed packaging bag can be dried on both sides at the same time. The dried packaging bag can be rolled up to form a continuous drying process, reducing the manpower and equipment input in the intermediate links, reducing production costs, and eliminating the need for manual or mechanical turning for secondary processing. This greatly shortens the drying cycle, increases the throughput per unit time, and improves the drying efficiency of the packaging bag.

[0041] The control method in this application is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so the control method and circuit connection will not be explained in detail in this application. The device is powered by an external power supply.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
