Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bag printing, in particular to a packaging bag printing and drying device. Background Art

[0002] During the printing process of packaging bags, a drying device is required to dry the surface of the packaging bags. Existing drying devices usually use hot air for direct drying. When the surface of the packaging bags is relatively moist, the drying efficiency of the drying device on the packaging bags is low.

[0003] A search revealed a solution for a packaging bag printing and drying device (Announcement No. CN221161872U), which includes a drying box with a position sensor installed on the inner top wall. Two fixed plates are fixedly connected to the inner wall of the drying box. The upper surface of each fixed plate has two sliding holes, each of which has a sliding column inside. The outer surface of each sliding column is covered with a spring. The top of each set of sliding columns is fixedly connected to a connecting plate. The connecting plate is pushed by an electric push rod, and the lower pressure plate compresses and fixes the packaging bag, replacing manual operation and ensuring the drying efficiency of the packaging bag. However, the device does not consider vibrating the printed packaging bags to shake off large water droplets on the packaging bag surface for auxiliary drying, resulting in low drying efficiency of the drying device for printed packaging bags. Utility Model Content

[0004] The purpose of the utility model is to provide a packaging bag printing and drying device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a packaging bag printing and drying device, comprising:

[0006] A drying box for drying printed packaging bags, with connection boxes connected to both sides of the drying box, an electric heating plate for drying packaging bags fixedly connected to the inner wall of the connection box, and a fan installed on the side of the connection box;

[0007] The toggle assembly is used to assist in drying the packaging bags during the printing process. The toggle assembly includes a linear motor and a connecting plate. The moving part of the linear motor is welded to the connecting plate. C-shaped moving plates are welded at both ends of the bottom of the connecting plate. The top wall and the bottom wall of the moving plate are both embedded with fixed bearings. The inner ring of the fixed bearing is interference fit with a rotating block. Rotating rollers for vibrating the packaging bags are welded on the adjacent sides of the two rotating blocks.

[0008] Preferably, a through slot 1 is provided on the top wall of the drying box body, and the fixed end of the linear motor is mounted on the inner wall of the through slot 1 of the drying box body.

[0009] Preferably, both end surfaces of the rotating drum are rotatably connected to the movable plate, and support frames are embedded and fixedly connected to the two inner side walls of the drying box.

[0010] Preferably, the inner wall of the support frame is rotatably connected to two fixed rollers for clamping the packaging bags, and gears are welded to the bottom surfaces of the two fixed rollers, and the two gears are meshed with each other.

[0011] Preferably, a rotating motor is installed on the top surface of the right support frame, and the output shaft of the rotating motor is connected to the fixed roller through a coupling.

[0012] Preferably, four support rods arranged in an array are welded to the bottom surface of the drying box.

[0013] Preferably, a second through groove is provided on the top surface of the drying box body, and a filter is fixedly connected to the inner wall of the second through groove of the drying box body.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] The packaging bag printing and drying device draws external air into the connection box through a fan, and at the same time electrically connects the electric heating plate inside the connection box to an external power supply device, so that the electric heating plate generates heat, and the heated air is introduced into the drying box to dry the packaging bags in the printing process. Since the large water droplets on the surface of the packaging bags have low drying efficiency when directly drying them, the linear motor is provided with power, so that the moving part of the linear motor drives the connection plate to move its position during movement. During the transmission process, the two rotating rollers knock and vibrate the packaging bags to shake off the large water droplets on the surface of the packaging bags, thereby improving the drying efficiency of the drying device for the packaging bags. The fixed bearings and rotating blocks are provided to achieve rolling contact between the rotating rollers and the packaging bags to prevent scratches on the packaging bags.

[0016] The packaging bag printing and drying device allows water vapor inside the drying box to be discharged through a filter screen. A support rod is provided to support the drying box, so that the packaging bags to be dried are clamped and fixed by two pairs of fixed rollers. A rotating motor is provided to provide power, so that the output shaft of the rotating motor drives the fixed rollers to rotate during rotation. Under the meshing action of the gears, the two fixed rollers rotate synchronously in opposite directions, providing a conveying effect for the packaging bags, and at the same time facilitating the tightening of the packaging bags. The clamped packaging bags are in a vertical state, which facilitates the falling of large water droplets on the surface of the packaging bags, providing auxiliary drying effect for the packaging bags, and enhancing the drying processing efficiency of the drying device for the packaging bags.

[0027] In order to solve the problem that the packaging bag printing and drying device does not vibrate the packaging bag to shake off the large water droplets on the surface of the packaging bag, thereby reducing the drying efficiency of the drying device for the packaging bag, please refer to Figures 1 to 4 The structure of the device body includes:

[0028] A drying box 1 for drying printed packaging bags, with connection boxes 10 connected to both sides of the drying box 1, an electric heating plate 11 for drying packaging bags fixedly connected to the inner wall of the connection box 10, a fan 9 installed on the side of the connection box 10, the fixed end of the fan 9 is detachably connected to the connection box 10 by a bolt, and the output end of the fan 9 is connected to the connection box 10, the outside air is drawn by the fan 9 into the interior of the connection box 10, and the heat is provided by the electric heating plate 11 inside the connection box 10 to heat the introduced air, thereby introducing the hot air into the drying box 1, and drying the packaging bags in the printing process inside the drying box 1;

[0029] The toggle assembly 2 is used to assist in drying the packaging bags during the printing process, so that the toggle assembly 2 can knock and vibrate the printed packaging bags to shake off the larger water droplets on the surface of the packaging bags, thereby achieving auxiliary drying of the packaging bags and improving the drying efficiency of the drying device for the packaging bags. The toggle assembly 2 includes a linear motor 3 and a connecting plate 4. The linear motor 3 is provided to provide power. The moving part of the linear motor 3 is welded to the connecting plate 4. During the movement of the moving part of the linear motor 3, the connecting plate 4 is driven to move in a lateral position. C-shaped moving plates 5 are welded at both ends of the bottom of the connecting plate 4, so that the two moving plates 5 are welded to the bottom surface of the connecting plate 4. Under the connection provided by the connecting plate 4, the moving part of the linear motor 3 drives the two moving plates 5 to move during the movement. At the same time, the inner side walls of the two moving plates 5 are arranged centripetally, and the inner top wall and the inner bottom wall of the moving plate 5 are both embedded and fixedly connected with a fixed bearing 6;

[0030] The inner ring of the fixed bearing 6 is interference-fitted with a rotating block 7. The fixed bearing 6 fixes the rotation position of the rotating block 7 and realizes the relative rotation of the rotating block 7 and the movable plate 5. The adjacent sides of the two rotating blocks 7 are welded with rotating rollers 8 for vibrating the packaging bag. The rotation position of the rotating rollers 8 is fixed during the transmission process, so that the moving part of the linear motor 3 moves. During the transmission process, the two rotating rollers 8 knock and vibrate the packaging bag to shake off large water droplets on the surface of the packaging bag. At the same time, the rotating rollers 8 roll on the side of the packaging bag to prevent the packaging bag from being scratched.

[0031] A through slot is provided on the top wall of the drying box 1. The fixed end of the linear motor 3 is mounted on the inner wall of the through slot of the drying box 1. The inner wall of the through slot of the drying box 1 is detachably connected to the fixed end of the linear motor 3 by bolts, thereby fixing the position of the linear motor 3 and improving the structural stability of the device components. The two end surfaces of the rotating drum 8 are rotatably connected to the movable plate 5, further enhancing the rotational stability of the rotating drum 8. Support frames 14 are embedded and fixedly connected to the two inner side walls of the drying box 1, so that the two support frames 14 are connected to the drying box 1. At the same time, the two support frames 14 are symmetrically arranged with the drying box 1 as the symmetry axis.

[0032] The inner wall of the support frame 14 is rotatably connected to two fixed rollers 15 for clamping the packaging bags, so that the top surface and the bottom surface of the two fixed rollers 15 are rotatably connected to the inner top wall and the inner bottom wall of a support frame 14 respectively, thereby fixing the two fixed rollers 15. At the same time, the four fixed rollers 15 are arranged vertically, so that the packaging bags clamped by the two pairs of fixed rollers 15 are arranged vertically, so that large water droplets on the surface of the packaging bags fall off, further assisting in drying the packaging bags, and improving the drying efficiency of the drying device for the packaging bags. Gears are welded on the bottom surfaces of the two fixed rollers 15, and the two gears mesh with each other. Under the meshing action of the gears, the two fixed rollers 15 move synchronously in opposite directions. A rotating motor 16 is installed on the top surface of the right support frame 14, and the fixed end of the rotating motor 16 is detachably connected to the top surface of the right support frame 14 by bolts;

[0033] The position of the rotating motor 16 is fixed, and the output shaft of the rotating motor 16 is connected to the fixed roller 15 through a coupling, so that the fixed roller 15 is driven to rotate during the rotation of the output shaft of the rotating motor 16, so that the two fixed rollers 15 convey the packaging bags during the rotation, and at the same time tighten the packaging bags, so that when the packaging bags are located inside the drying box 1, they are arranged vertically, which facilitates the falling of larger water droplets adhering to the surface of the packaging bags under the action of gravity, enhances the auxiliary drying effect of the packaging bags, and improves the drying efficiency of the drying device for the packaging bags. Four support rods 13 arranged in an array are welded to the bottom surface of the drying box 1, and a through groove 2 is opened on the top surface of the drying box 1. The inner wall of the through groove 2 of the drying box 1 is fixedly connected to a filter screen 12, so that the water vapor inside the drying box 1 is discharged through the filter screen 12.

[0034] The linear motor 3, the fan 9, the electric heating plate 11, and the rotary motor 16 are all prior arts. Their working principles, sizes, and models are irrelevant to the functions of the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0035] How it works

[0036] When using the packaging bag printing and drying device, the user clamps the printed packaging bags between two pairs of fixed rollers 15 and starts the rotating motor 16. The output shaft of the rotating motor 16 drives the fixed rollers 15 to rotate during rotation. Under the meshing action of the gears, the two fixed rollers 15 convey the packaging bags during rotation, so that the packaging bags are in a vertical arrangement state. Under the action of gravity, water droplets are separated from the surface of the packaging bags. The fan 9 and the electric heating plate 11 are energized to introduce hot air into the drying box 1 to dry the packaging bags.

[0037] Start the linear motor 3. The moving part of the linear motor 3 drives the connecting plate 4 to move in position during the movement. Under the connection provided by the moving plate 5, the two rotating rollers 8 alternately hit the packaging bag to shake off the larger water droplets on the surface of the packaging bag. The fixed bearing 6 fixes the rotation position of the rotating block 7, so that the rotating rollers 8 are in rolling contact with the packaging bag.
