Description

Technical Field

[0001] This utility model relates to the field of label printing technology, specifically to a label printing correction mechanism. Background Art

[0002] Label printing is a label manufacturing process that uses printing technology to print images, text, barcodes, QR codes, and other information onto label materials. Label printing is widely used in various fields, such as food packaging, pharmaceutical packaging, and electronic products. Label printing can be classified in many ways, such as by material (paper labels and plastic labels) and by printing method (letterpress printing, offset printing, digital printing, etc.). Different types of labels and printing methods have their own applicable scope and characteristics.

[0003] A search revealed Chinese utility model patent CN221051113U, which describes an automatic correction mechanism for a label printing machine. The mechanism includes a mounting frame, a guide rail fixedly connected to the inner side of the mounting frame, and a correction component slidably connected to the lower surface of the guide rail. A drive mechanism for adjusting the correction component is also mounted on the inner side of the mounting frame. In this utility model, a drive mechanism and a correction component are provided. When the label deviates, a second motor rotates, and the threaded sleeve rotates along with the second motor, driving the screw to rotate. The screw pushes a clamping plate, and the clamping plate, under pressure, drives a first slider to slide along the guide rail, changing the distance between the clamping plates and limiting the label's movement to prevent it from deviating.

[0004] The existing device has the following problems when in use: the labels carry dust from the air during transmission, which then adheres to the labels. If not cleaned in time, it reduces the quality of subsequent printing. Secondly, the labels come into contact with the fixed limiting structure during transmission, which affects the transmission of its own conveying force and accelerates the phenomenon of label deviation. Utility Model Content

[0005] The purpose of this invention is to provide a label printing correction mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a label printing correction mechanism, comprising a housing, a dust collection box, and a control chamber. Dust collection boxes are provided on both sides of the housing, a fan is provided on one side of each dust collection box, and a control chamber is provided on one side of the housing. A conveying roller is installed inside the housing, and a conductive film is provided on the outer surface of the conveying roller. A base is connected to the bottom of the housing, a lead screw is provided inside the base, and a slide is threaded onto the surface of the lead screw. A frame is provided on the top of the slide, and a mounting shell is fixedly connected to one side of the frame. A limit roller is installed inside the mounting shell.

[0007] By adopting the above technical solution, the label enters between two sets of conveying rollers, and the groove on the limiting roller inside the mounting shell is aligned with the label, so that the two sides of the label are limited by the limiting roller to prevent deviation. The electrostatic dust on the label is removed by the conductive film. The removed dust floats in the shell, and the fan is started to suck up the dust in the air. When the dust passes through the electrode plate in the dust removal box, it is adsorbed, thereby reducing the electrostatic dust carried on the label and affecting the subsequent printing effect.

[0008] Preferably, a handle is rotatably provided on one side of the base, and a lead screw is fixedly connected to one end of the handle.

[0009] By adopting the above technical solution, the distance of the limit roller can be adjusted by rotating the lead screw through the handle.

[0010] Preferably, a rotating motor is installed on one side of the safety control compartment, and a main gear is fastened to the output end of the rotating motor. The main gear meshes with a secondary gear, and a conveying roller is connected to one side of both the main gear and the secondary gear.

[0011] By adopting the above technical solution, the starting motor drives the main gear, which in turn meshes with and drives the auxiliary gear. In turn, the main gear and auxiliary gear drive the conveyor roller to transport the labels.

[0012] Preferably, U-shaped plates are provided on both sides of the interior of the dust collector box, and electrode plates are snapped into the interior of the U-shaped plates.

[0013] By adopting the above technical solution, it is easy to remove the electrode plate, thereby cleaning the dust on the electrode plate.

[0014] Preferably, an air inlet mesh is provided on one side of the dust collection box, and a scale line is provided on one side of the base.

[0015] By adopting the above technical solution, the distance of the limit roller is adjusted according to the scale lines.

[0016] Preferably, the base has a slot, and a slide is provided inside the slot.

[0017] By adopting the above technical solution, the slide moves within the slot.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. Static dust on the label is removed by a conductive film. The removed dust floats on the housing. The fan is turned on to suck up the dust in the air. The dust is adsorbed as it passes through the electrode plate in the dust removal box, thereby reducing the static dust on the label and affecting the subsequent printing effect.

[0020] 2. Align the groove on the limiting roller inside the mounting housing with the label, so that the two sides of the label are limited by the limiting roller to prevent deviation. When the label is conveyed, the limiting roller rotates to prevent the conveying force from weakening, thus maintaining stable conveying. Attached Figure Description

[0027] This utility model provides a technical solution: a label printing correction mechanism. (Please refer to...) Figure 1 , Figure 2 The bottom of the housing 1 is connected to a base 6. A lead screw 8 is installed inside the base 6. A slide 9 is threaded onto the surface of the lead screw 8. A frame 5 is installed on the top of the slide 9. A mounting shell 4 is fixedly connected to one side of the frame 5. A limiting roller 3 is installed inside the mounting shell 4. A handle 7 is rotatably installed on one side of the base 6. One end of the handle 7 is fixedly connected to the lead screw 8. A slot is opened on the base 6. The slide 9 is installed inside the slot. A scale line is set on one side of the base 6. When the label enters between the two sets of conveying rollers 2, the handle 7 is rotated to drive the lead screw 8 to rotate. The lead screw 8, in conjunction with the slide 9, drives the top frame 5 to move. The mounting shell 4 on one side of the frame 5 moves accordingly, aligning the groove on the limiting roller 3 inside the mounting shell 4 with the label. Thus, the two sides of the label are limited by the limiting roller 3 to prevent deviation and improve the label printing effect.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Dust collection boxes 14 are provided on both sides of the housing 1. A fan 12 is provided on one side of the dust collection box 14. A control chamber 10 is provided on one side of the housing 1. A conveying roller 2 is installed inside the housing 1. A conductive film 15 is provided on the outer surface of the conveying roller 2. U-shaped plates 16 are provided on both sides of the inside of the dust collection box 14. Electrode plates 13 are snapped into the inside of the U-shaped plates 16, so that the electrode plates 13 can be easily removed for dust removal.

The main gear meshes with a secondary gear, and both the main gear and the secondary gear are connected to a conveyor roller 2 on one side. When the motor 11 is started, it drives the main gear to rotate, and the main gear meshes with the secondary gear to rotate, thereby conveying the label by the conveyor roller 2. An air inlet mesh 17 is provided on one side of the dust removal box 14. The electrostatic dust on the label is removed by the conductive film 15. The removed dust floats on the housing 1. The fan 12 is started to suck up the dust in the air. When the dust passes through the electrode plate 13 in the dust removal box 14, it is adsorbed, thereby reducing the electrostatic dust carried on the label and affecting the subsequent printing effect.

[0029] Working principle: The label enters between the two sets of conveying rollers 2. Turning the handle 7 drives the lead screw 8 to rotate. The lead screw 8, in conjunction with the slide block 9, drives the top frame 5 to move. The mounting shell 4 on one side of the frame 5 moves accordingly, aligning the groove on the limiting roller 3 inside the mounting shell 4 with the label. Thus, the two sides of the label are limited by the limiting roller 3 to prevent deviation. The static dust on the label is removed by the conductive film 15. The removed dust floats on the shell 1. The fan 12 is started to suck up the dust in the air. When the dust passes through the electrode plate 13 in the dust removal box 14, it is adsorbed, thereby reducing the static dust carried on the label and affecting the subsequent printing effect.
