Description

Technical Field

[0001] This utility model relates to a correction mechanism, and more particularly to a correction mechanism for a label inkjet printer. Background Technology

[0002] The correction mechanism of an inkjet printer is a device used to automatically correct the lateral deviation of roll material or labels during the printing process. Its core function is to ensure the accuracy of the printing position and avoid printing quality problems caused by material deviation.

[0003] For example, a carton production inkjet printer with corrective properties, disclosed in Chinese Patent Publication No. CN220662051U, includes a conveyor and an inkjet printer mounted on one side of the conveyor. A first guide plate is fixedly connected to one side of the inkjet printer, and a correction component is mounted on the other side of the conveyor. The correction component includes a connecting plate fixed to the side of the conveyor, an adjustment hole on the connecting plate, an adjustment plate on the inner side of the connecting plate, and an adjustment rod fixedly connected to the outer end of the adjustment plate, matching the adjustment hole. A fixing button is threaded onto the adjustment rod located on the outer side of the connecting plate. A correction hole is provided on the adjustment plate, and a correction element is movably mounted in the correction hole. The correction element is matched with the first guide plate. By setting the correction component, the lateral limiting width of the carton's path can be adjusted according to the size of the carton. By restricting the carton, it can be kept relatively parallel to the inkjet printer during inkjet printing, preventing the carton from shifting or tipping over during operation. Some problems were found when using the existing carton production inkjet printer with corrective deviation. First, the first guide plate is used to guide the carton in the off-position to deflect. At this time, the corners of the carton will disengage from the guide plate and rub against it, which causes the corners of the carton to be worn during the initial guidance and correction process. Utility Model Content

[0004] The purpose of this invention is to provide a correction mechanism for a label inkjet printer to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a correction mechanism for a label inkjet printer, including a support, and further comprising: Mounting frame, on which a rotating guide belt is rotatably mounted; A limiting plate, one end of which is provided with an arc-shaped connecting groove, which cooperates with the rotating guide belt; A connecting bracket, used to connect a fixed mounting bracket and a limiting plate; An adjusting mechanism is provided, comprising an internal threaded sleeve and a threaded adjusting rod. The threaded adjusting rod is rotatably mounted in a bracket via a bearing. One end of the internal threaded sleeve is fixedly connected to a connecting bracket, and the threaded adjusting rod is threadedly mounted in the internal threaded sleeve.

[0006] Preferably, a telescopic support rod is fixedly connected to one side of the bracket, and the other end of the telescopic support rod is fixedly connected to the connecting bracket.

[0007] Preferably, one end of the threaded adjusting rod passes through the bracket and is fixedly connected to a knob.

[0008] Preferably, the mounting frame has bearing seats symmetrically fixed to one side, and a roller is rotatably mounted between the two bearing seats, with the rotating guide belt sleeved on the roller.

[0009] Preferably, one side of the limiting plate is polished.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. When the corners of the carton come into contact with the rotating guide belt, the carton moves forward and the friction will drive the rotating guide belt to rotate. The rotation of the rotating guide belt will guide and correct the position of the carton, thereby minimizing the friction between the carton and the device during the correction process, which would cause wear on the corners of the carton.

[0011] 2. Rotating the threaded adjusting rod can move the internal threaded sleeve, which in turn moves the connecting bracket, which in turn moves the mounting frame and the limiting plate. This allows for adjustment of the position of the correction mechanism composed of the mounting frame and the limiting plate, thus adapting to the correction of cartons of different widths.

[0014] 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.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a correction mechanism for a label inkjet printer, including a bracket 1, and further comprising: Mounting bracket 2, on which a rotating guide belt 203 is rotatably mounted; The limiting plate 3 has an arc-shaped connecting groove 301 at one end, which cooperates with the rotating guide belt 203. Connecting bracket 4 is used to connect and fix the mounting bracket 2 and the limiting plate 3; The adjustment mechanism includes an internal threaded sleeve 102 and a threaded adjustment rod 103. The threaded adjustment rod 103 is rotatably mounted in the bracket 1 via a bearing. One end of the internal threaded sleeve 102 is fixedly connected to the connecting bracket 4. The threaded adjustment rod 103 is threadedly mounted in the internal threaded sleeve 102.

[0016] In this embodiment, the device is symmetrically fixed on the conveyor belt of the label inkjet printer. The mounting frame 2 and the limiting plate 3 are connected together using the connecting bracket 4. The mounting frames 2 on both sides of the conveyor belt form an inverted V-shape, gathering the conveyed cartons and centering them in the middle. Simultaneously, the rotating guide belt 203 is rotatably mounted on one side of the mounting frame 2. The rotating guide belt 203 directly contacts the cartons. When the corners of the cartons contact the rotating guide belt 203, the forward movement of the cartons, through friction, drives the rotating guide belt 203 to rotate. The transfer guides and corrects the position of the carton, thereby minimizing friction between the carton and the device during the correction process, which could lead to wear on the edges and corners of the carton. The threaded adjusting rod 103 is threadedly engaged with the internal threaded sleeve 102. Rotating the threaded adjusting rod 103 can move the internal threaded sleeve 102, which in turn can move the connecting bracket 4. The moving of the connecting bracket 4 can then move the mounting frame 2 and the limiting plate 3, thereby adjusting the position of the correction mechanism composed of the mounting frame 2 and the limiting plate 3 to adapt to the correction of cartons of different widths.

[0017] In order to achieve the purpose of connecting bracket 1 and connecting bracket 4, the device adopts the following technical solution: a telescopic support rod 101 is fixedly connected to one side of bracket 1, the other end of the telescopic support rod 101 is fixedly connected to connecting bracket 4, and a knob 104 is fixedly connected to one end of the threaded adjustment rod 103 through bracket 1.

[0018] The connecting bracket 4 is connected by the telescopic support rod 101, which provides sufficient vertical support and restricts the connecting bracket 4 to move only left and right. The threaded adjustment rod 103 can be rotated by the knob 104.

[0019] In order to achieve the purpose of rotating the guide belt 203 to be rotatably installed on one side of the mounting frame 2, the device adopts the following technical solution: bearing seats 201 are symmetrically fixed on one side of the mounting frame 2, and a roller shaft 202 is rotatably installed between the two bearing seats 201. The rotating guide belt 203 is sleeved on the roller shaft 202, and the limit plate 3 is polished on one side.

[0020] Several rollers 202 are rotatably supported by bearing housing 201. The rollers 202 provide support for the rotating guide belt 203, thereby allowing the rotating guide belt 203 to be rotatably mounted on one side of the mounting frame 2. At the same time, the side seat of the limiting plate 3 is polished to minimize excessive friction between the limiting plate 3 and the carton.

[0021] The working principle and usage process of this utility model are as follows: The bracket 1 is fixed on the conveyor belt of the label inkjet printer. Two sets of devices need to be set symmetrically. The knob 104 drives the threaded adjustment rod 103 to rotate. The rotation of the threaded adjustment rod 103 can drive the internal threaded sleeve 102 to move. The movement of the internal threaded sleeve 102 can drive the connecting bracket 4 to move. The connecting bracket 4 drives the limiting plate 3 and the mounting bracket 2 to move. The distance between the two symmetrically set limiting plates 3 is adjusted to the width of the carton. During the carton's transmission, the corners of the carton contact the rotating guide belt 203. The forward movement of the carton will drive the rotating guide belt 203 to rotate through friction. The rotation of the rotating guide belt 203 will guide and correct the position of the carton, thereby minimizing friction between the carton and the device during the correction process. The mounting bracket 2 and the limiting plate 3 are used to limit and correct the position of the carton, which facilitates the subsequent operation of the label inkjet printer.

[0022] 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.
