Description

Technical Field

[0001] This utility model relates to the field of inkjet printing technology, specifically a green inkjet printing device for cigarette packs. Background Technology

[0002] When people buy cigarettes, the coding on the cigarette box and the spray code on the carton are the basis for distinguishing the authenticity of cigarettes. With the improvement of consumers' awareness of consumer rights protection, the coding of cigarettes, especially the spray code on the carton, has become the basic basis for consumers to protect their rights.

[0003] Currently, inkjet printers are commonly used for coding cigarette packs. For example, Chinese patent application CN202121094978.0 describes a cigarette pack coding device, which includes a base, a support rod, and a conveyor belt. The conveyor belt is located at the top center of the base. This cigarette pack coding device uses a fixed frame and a support rod. The fixed frame has a through hole tangent to the outer side of the support rod on the left side away from the base. When one side of the cigarette pack contacts the fixed block, and the cigarette pack is tilted, the fixed block on one side of the connecting rod contacts the cigarette pack, while the fixed block on the other side of the connecting rod moves away from the cigarette pack. The other side of the cigarette pack is subjected to a pushing force, and the forces on both sides of the fixed block reach a balanced state, causing the two fixed blocks to contact the outer side of the cigarette pack. The cigarette pack is then in a vertical position, thus fixing its position.

[0004] However, in actual use, when workers place cigarette packs of different sizes on the conveyor belt and the inkjet printer is in a fixed position, the cigarette packs are not initially placed flat or directly below the inkjet printer. This can easily cause the inkjet printer to shift during the printing process, reducing the printing effect, making it easy to print errors and requiring rework, thus failing to achieve the goal of green inkjet printing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a green inkjet printing device for cigarette packs. By limiting the position of cigarette packs of different sizes, it avoids inkjet printing deviation caused by the initial position of the cigarette packs not being placed flat or not being placed directly below the inkjet printer, thus ensuring the inkjet printing effect and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a green inkjet printing device for cigarette packs, comprising a U-shaped base and a top plate fixedly disposed on the top of the U-shaped base, wherein an inkjet printer is fixedly disposed on the top of the top plate, and a conveyor is fixedly disposed inside the U-shaped base;

[0007] A limiting component is fixedly provided on one side of the U-shaped base to limit the position of the cigarette pack and ensure the coding effect;

[0008] The limiting component includes two fixing plates, which are respectively fixed at the front and rear ends of one side of the U-shaped base. The top of the fixed plate has a slot, and the top and bottom of the slot are connected by a bearing to the same rotating rod. The rotating rod is fixed with a limiting plate, and the limiting plate is located at the top of the conveyor, so that the two limiting plates can move closer or further apart to limit the position of the cigarette pack.

[0009] Preferably, two vertically distributed fixed boxes are fixedly provided on both the front and rear sides of the U-shaped base. A bevel gear set is provided inside the fixed box. A hinge seat is fixedly provided on the side of the limiting plate near the U-shaped base. A threaded cylinder is rotatably provided on the hinge seat. A threaded rod is rotatably provided inside the threaded cylinder, which facilitates the threaded rod to drive the threaded cylinder to move back and forth.

[0010] Preferably, the end of the threaded rod away from the threaded cylinder passes through one side of the U-shaped base and is fixedly connected to one of the bevel gears in the top bevel gear set, and the threaded rod is connected to the U-shaped base by a bearing, which facilitates the bottom bevel gear set to rotate relative to each other and drive the threaded rod to rotate.

[0011] Preferably, a dual-axis motor is fixedly installed at the bottom of one side of the U-shaped base. Both output shafts of the dual-axis motor are fixedly equipped with rotating shafts. The end of the rotating shaft away from the dual-axis motor passes through one side of the U-shaped base and is fixedly connected to one of the bevel gears in the bottom bevel gear set. The rotating shaft is connected to the U-shaped base through a bearing, which facilitates the rotating shaft to drive the bottom bevel gear set to rotate.

[0012] Preferably, the bevel gears in the two bevel gear sets on the same side are fixedly connected by a connecting rod, and the connecting rod passes through the fixed box and is connected to the fixed box by a bearing, so that the two bevel gear sets on the same side can rotate relative to each other through the connecting rod.

[0013] Preferably, a through-beam photoelectric switch is fixedly installed on the center of the rear side inside the U-shaped base, and a control panel is fixedly installed on the front side of the U-shaped base for controlling the operation of the conveyor, through-beam photoelectric switch, inkjet printer and dual-axis motor, so as to facilitate the operation of the control panel to control the conveyor, through-beam photoelectric switch, inkjet printer and dual-axis motor.

[0014] Preferably, the top of the conveyor is fixed with several evenly distributed anti-slip pads, and the four corners of the bottom of the U-shaped base are fixed with casters to facilitate the movement of this utility model.

[0015] Compared with the prior art, this utility model provides a green inkjet coding device for cigarette packs, which has the following beneficial effects:

[0016] This invention uses a dual-axis motor to drive the rotating shaft, which in turn drives each set of bevel gears to rotate. Simultaneously, the rotation of the bevel gears in the top set of bevel gears drives the threaded rod to move the threaded cylinder back and forth, and pushes the limiting plate to tilt. This facilitates the movement of the two limiting plates closer or further apart to limit the size of cigarette packs, preventing the initial position of the cigarette packs from being uneven or not placed directly below the inkjet printer, which could cause inkjet offset. This ensures the effectiveness of the inkjet printing and achieves green inkjet printing. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, this utility model provides a green inkjet printing device for cigarette packs, including a U-shaped base 1 and a top plate 2 fixedly installed on the top of the U-shaped base 1. An inkjet printer 3 is fixedly installed on the top of the top plate 2. A conveyor 4 is fixedly installed inside the U-shaped base 1. Several evenly distributed anti-slip pads 5 are fixedly installed on the top of the conveyor 4. The four corners of the bottom of the U-shaped base 1 are all fixedly equipped with casters 10 to facilitate the movement of this utility model.

[0026] like Figure 1-5As shown, a limiting component 7 is fixedly provided on one side of the U-shaped base 1 to limit the position of the cigarette pack and ensure the coding effect. The limiting component 7 includes two fixing plates 71, which are respectively fixed at the front and rear ends of one side of the U-shaped base 1. The top of the fixing plate 71 has a slot. The top and bottom of the slot are connected by a bearing to the same rotating rod 72. A limiting plate 73 is fixedly provided on the rotating rod 72 and is located on the top of the conveyor 4, so that the two limiting plates 73 can move closer or further away from each other to limit the position of the cigarette pack.

[0027] Two fixed boxes 8 are fixedly installed on the front and rear sides of the U-shaped base 1, arranged vertically. The fixed boxes 8 are equipped with bevel gear sets 77. A hinge seat 76 is fixedly installed on the side of the limiting plate 73 near the U-shaped base 1. A threaded cylinder 75 is rotatably installed on the hinge seat 76. A threaded rod 74 is rotatably installed inside the threaded cylinder 75, which facilitates the threaded rod 74 to drive the threaded cylinder 75 to move back and forth. The end of the threaded rod 74 away from the threaded cylinder 75 passes through one side of the U-shaped base 1 and is fixedly connected to one of the bevel gears in the top bevel gear set 77. The threaded rod 74 is connected to the U-shaped base 1 through a bearing, which facilitates the bottom bevel gear set 77 to rotate and drive the threaded rod 74 to rotate. A dual-axis motor 710 is fixedly installed at the bottom of one side of the U-shaped base 1. The output shafts of the dual-axis motor 710 are fixedly equipped with rotating shafts 79 at both ends.

[0028] The end of the rotating shaft 79 away from the dual-axis motor 710 passes through one side of the U-shaped base 1 and is fixedly connected to one of the bevel gears in the bottom bevel gear set 77. The rotating shaft 79 and the U-shaped base 1 are connected by a bearing, which facilitates the rotating shaft 79 to drive the bottom bevel gear set 77 to rotate. The bevel gears in the two bevel gear sets 77 on the same side are fixedly connected by a connecting rod 78. The connecting rod 78 passes through the fixed box 8 and is connected to the fixed box 8 by a bearing, which facilitates the two bevel gear sets 77 on the same side to rotate relative to each other by the connecting rod 78. The front side of the U-shaped base 1 is fixedly provided with a control panel 9 for controlling the operation of the conveyor 4, the through-beam photoelectric switch 6, the inkjet printer 3 and the dual-axis motor 710. This facilitates the operation of the control panel 9 to control the conveyor 4, the through-beam photoelectric switch 6, the inkjet printer 3 and the dual-axis motor 710.

[0029] By setting the limiting component 7, the control panel 9 controls the dual-axis motor 710 to work according to the size of the cigarette pack to be printed. The dual-axis motor 710 drives the rotating shaft 79 to rotate, and at the same time drives the two sets of bevel gears 77 to rotate around the connecting rod 78 respectively. Meanwhile, the rotation of one bevel gear in the top set of bevel gears 77 drives the threaded rod 74 to rotate. The rotation of the threaded rod 74 drives the threaded cylinder 75 to move back and forth, and pushes the limiting plate 73 to tilt, so that one end of the limiting plate 73 rotates around the rotating rod 72 and the other end rotates around the hinge seat 76. This makes it easy to drive the two limiting plates 73 to move closer or further apart to limit the size of cigarette packs of different sizes, and avoid the printing offset caused by the initial position of the cigarette pack not being placed flat or not being placed directly under the inkjet printer, thus ensuring the printing effect.

[0030] like Figure 1 , 4 As shown, a through-beam photoelectric switch 6 is fixedly installed on the center of the rear side inside the U-shaped base 1. The through-beam photoelectric switch 6 is composed of a photoelectric transmitter and a photoelectric receiver, and is fixedly installed on the front side and the rear side inside the U-shaped base 1, respectively.

[0031] After adjusting the position between the two limit plates 73, place the cigarette pack between them. Operate the control panel 9 to control the conveyor 4 to transport the cigarette pack. The position of the cigarette pack is detected by the through-beam photoelectric switch 6 (when the cigarette pack enters the optical path between the photoelectric receiver and the photoelectric transmitter, it will block the light beam, causing the photoelectric receiver to be unable to receive the light signal, which indicates that the cigarette pack has been detected. Conversely, when the cigarette pack leaves the optical path, the light beam is received again by the photoelectric transmitter, which indicates that the cigarette pack has not been detected). When the through-beam photoelectric switch 6 detects the cigarette pack, it will send a signal to the control panel 9, causing the control panel 9 to control the inkjet printer 3 to print the cigarette pack (the working principle of the inkjet printer 3 is to use the deflection of the charged ink to deflect the ink droplets off the normal flight path and shoot them onto the surface of the cigarette pack, using the charge of the ink droplets to control the position of each ink droplet), thereby realizing the cigarette pack printing process, ensuring the printing effect, and achieving green printing.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
