Abstract
Description
Technical Field
[0001] This utility model relates to the field of inkjet printer technology, and specifically to a laser positioning device for an inkjet printer. Background Technology
[0002] A coding machine is a software-controlled device that marks products using a non-contact method. It generally refers to continuous inkjet technology, and laser coding machines are one type. Laser coding machines have inductive positioning coding devices, and some inductive positioning coding devices are directly installed on the conveyor belt.
[0003] In the process of developing this application, the following problems were found with the technology: In the process of using the existing laser positioning device for inkjet printers, the conveying equipment continuously transports the inkjet-printed items, which causes some inkjet-printed items to be missed when transported too fast, thus reducing the practicality of the device.
[0004] Therefore, a laser positioning device for inkjet printers is proposed. Utility Model Content
[0005] The purpose of this invention is to solve the problem that existing laser positioning devices for inkjet printers, which continuously transport items for coding during use, may result in missed coding of some items when the transport is too fast. This invention provides a laser positioning device for inkjet printers.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A laser positioning device for an inkjet printer includes a conveying device and an inkjet printer. The conveying device includes two sets of side plates, each with a clamping mechanism on an opposite side. The upper surfaces of the two sets of side plates are provided with an adjustment mechanism that adjusts the movement according to the height of the conveyed item. The adjustment mechanism is electrically connected to the control terminal of the conveying device. The inkjet printer is mounted on the upper surface of the clamping mechanism.
[0008] Furthermore, the adjustment mechanism includes two sets of U-shaped fixing plates, which are respectively installed on the upper surfaces of the two sets of side plates. A motor is installed on the upper surface of each set of U-shaped fixing plates. A through hole is opened at the top of the inner wall of each set of U-shaped fixing plates. A screw is rotatably connected to the through hole in each set of U-shaped fixing plates. A slider is connected to the external thread of each set of screws. The sliders are slidably connected inside the two sets of U-shaped fixing plates. A fixing block is installed on the adjacent side of each set of sliders. An infrared detector is installed on the upper surface of each set of fixing blocks. The infrared detectors are electrically connected to the control terminals of the conveying device and the clamping mechanism.
[0009] Furthermore, the clamping mechanism includes two sets of L-shaped fixing plates, which are respectively installed on opposite sides of the two sets of side plates. Electric telescopic rods are provided on the inner walls of both sets of L-shaped fixing plates, and positioning plates are installed at the output ends of both sets of electric telescopic rods. Grooves are formed on adjacent sides of both sets of positioning plates, and pressure sensors are installed inside the grooves of both sets of positioning plates. The pressure sensors are electrically connected to the control ends of the adjacent set of electric telescopic rods. The inkjet printer is installed on the upper surface of the right-side set of L-shaped fixing plates.
[0010] Furthermore, a limiting plate is installed on the upper surface of both sets of side plates, and the positions of the adjacent sides of the two sets of limiting plates are parallel to the adjacent sides of the two sets of side plates, respectively.
[0011] Furthermore, the positions on opposite sides of the two sets of limiting plates are parallel to the adjacent positions of the two sets of infrared detectors.
[0012] Furthermore, the positions of the back sides of the two sets of limiting plates are located outside the movement paths of the two sets of positioning plates.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model activates two sets of motors to drive two sets of screws, triggering two sets of sliders to slide inside two sets of U-shaped fixed plates. During the sliding process, the two sets of sliders drive the two sets of fixed blocks and infrared detectors to move up and down. This allows the height of the two sets of infrared detectors to be quickly adjusted. When the two sets of infrared detectors detect the conveyed item, they trigger the shutdown of the conveying equipment, causing the subsequent conveying equipment to stop conveying the item. This minimizes the accumulation of items at the top of the conveying equipment, which could lead to the missed items when the subsequent conveying equipment is moving too fast. Therefore, the practicality of this device is improved.
[0015] 2. This utility model uses two sets of pressure sensors positioned between the two sets of positioning plates and the contact surfaces on both sides of the conveyed item. When the adjacent sides of the two sets of positioning plates abut against the left and right sides of the conveyed item, the two sets of pressure sensors are triggered to shut down the two sets of electric telescopic rods. This minimizes the risk of excessive compression of the conveyed item during the clamping and positioning process by the two sets of positioning plates, which could lead to damage to the conveyed item.

[0025] like Figures 1 to 4As shown, a laser positioning device for an inkjet printer includes a conveying device 1 and an inkjet printer 7. The conveying device 1 includes two sets of side plates 2, each with a clamping mechanism 3 on opposite sides. An adjustment mechanism 5, which adjusts the movement according to the height of the conveyed item, is provided on the upper surface of the two sets of side plates 2. The adjustment mechanism 5 is electrically connected to the control terminal of the conveying device 1. The inkjet printer 7 is mounted on the upper surface of the clamping mechanism 3. Specifically, by activating the adjustment mechanism 5, the detection height of the adjustment mechanism 5 is adjusted. When the adjustment mechanism 5 detects a conveyed item, it triggers the shutdown of the conveying device 1, causing subsequent conveying devices 1 to stop conveying items. This minimizes the possibility of subsequent conveyed items accumulating at the top of the conveying device 1, preventing uncoded items from being missed when the subsequent conveying device 1 moves too fast. Therefore, the practicality of the device is improved.
[0026] like Figures 1 to 4 As shown, the adjustment mechanism 5 includes two sets of U-shaped fixing plates 501. The two sets of U-shaped fixing plates 501 are respectively installed on the upper surface of the two sets of side plates 2. A motor 502 is provided on the upper surface of each set of U-shaped fixing plates 501. A through hole is opened on the top of the inner wall of each set of U-shaped fixing plates 501. A screw 506 is rotatably connected to the through hole of each set of U-shaped fixing plates 501. A slider 503 is connected to the external thread of each set of screws 506. The two sets of sliders 503 are slidably connected inside the two sets of U-shaped fixing plates 501. A fixing block 504 is installed on the adjacent side of each set of sliders 503. An infrared detector 505 is provided on the upper surface of each set of fixing blocks 504. The two sets of infrared detectors 505 are electrically connected to the control end of the conveying device 1 and the clamping mechanism 3.
[0027] Specifically, by activating two sets of motors 502, two sets of screws 506 are driven to trigger two sets of sliders 503 to slide inside two sets of U-shaped fixing plates 501. This causes the two sets of sliders 503 to move up and down, along with the two sets of fixing blocks 504 and infrared detectors 505. This allows for rapid height adjustment of the two sets of infrared detectors 505. When the two sets of infrared detectors 505 detect a transported item, they trigger the shutdown of the conveyor device 1, stopping the transport of items. This minimizes the risk of items piling up at the top of the conveyor device 1 and being missed when the conveyor device 1 is moving too fast. The device is designed to handle uncoded items, thus improving its practicality. Since the conveyor 1 does not immediately stop operating during shutdown, subsequent items are conveyed to the clamping mechanism 3 by the inertia of the conveyor 1. Electrical connections are then established between the two sets of infrared detectors 505 and the control terminal of the clamping mechanism 3, allowing the clamping mechanism 3 to clamp and position the items upon arrival. This minimizes the risk of errors in coding caused by the clamping mechanism 3's inability to adjust the positioning of items conveyed on the upper part of the conveyor 1, thereby enhancing the device's practicality.
[0028] like Figure 1 and Figure 2 As shown, the clamping mechanism 3 includes two sets of L-shaped fixing plates 302, which are respectively installed on opposite sides of the two sets of side plates 2. Each set of L-shaped fixing plates 302 has an electric telescopic rod 303 on its inner sidewall. Each set of electric telescopic rods 303 has a positioning plate 301 installed at its output end. Each set of positioning plates 301 has a groove on its adjacent side, and each set of positioning plates 301 has a pressure sensor 4 installed inside its groove. The two pressure sensors 4 respectively communicate electrically with the control end of the adjacent set of electric telescopic rods 303. The inkjet printer 7 is installed on the upper surface of a set of L-shaped fixing plates 302 on the right side. Specifically, by positioning two sets of pressure sensors 4 between the two sets of positioning plates 301 and the contact surfaces on both sides of the conveyed item, when the adjacent sides of the two sets of positioning plates 301 abut against the left and right sides of the conveyed item, the two sets of pressure sensors 4 are triggered to shut down the two sets of electric telescopic rods 303. This avoids excessive squeezing of the conveyed item during the clamping and positioning process of the two sets of positioning plates 301, which could lead to damage to the conveyed item.
[0029] like Figure 1 and Figure 2As shown, limit plates 6 are installed on the upper surfaces of both sets of side plates 2. The adjacent sides of the two sets of limit plates 6 are parallel to the adjacent sides of the two sets of side plates 2. Specifically, by keeping the adjacent sides of the two sets of limit plates 6 parallel to the adjacent sides of the two sets of side plates 2, the two sets of limit plates 6 restrict the movement path of the items conveyed at the top of the conveying device 1, thereby minimizing the risk of collision between the items conveyed at the top of the conveying device 1 and the two sets of infrared detectors 505, which could cause damage to the two sets of infrared detectors 505.
[0030] like Figure 1 and Figure 2 As shown, the positions of the two sets of limiting plates 6 on opposite sides are parallel to the adjacent ends of the two sets of infrared detectors 505. Specifically, by keeping the positions of the two sets of limiting plates 6 on opposite sides parallel to the adjacent ends of the two sets of infrared detectors 505, the positions of the subsequent two sets of limiting plates 6 are located outside the moving path of the two sets of infrared detectors 505, thereby minimizing the risk of the subsequent two sets of infrared detectors 505 colliding with the two sets of limiting plates 6 during their up-and-down movement, which could cause damage to the subsequent two sets of infrared detectors 505.
[0031] like Figure 1 and Figure 2 As shown, the backs of the two sets of limiting plates 6 are located outside the movement paths of the two sets of positioning plates 301, respectively. Specifically, by positioning the backs of the two sets of limiting plates 6 outside the movement paths of the two sets of positioning plates 301, the normal movement of the two sets of positioning plates 301 is minimized during subsequent use.
[0032] In summary: By activating two sets of motors 502, two sets of screws 506 are driven to trigger two sets of sliders 503 to slide inside two sets of U-shaped fixing plates 501. This causes the two sets of sliders 503 to move up and down, along with the two sets of fixing blocks 504 and infrared detectors 505. This allows for rapid height adjustment of the two sets of infrared detectors 505. When the two sets of infrared detectors 505 detect a transported item, they trigger the shutdown of the conveyor device 1, stopping the transport of items. This minimizes the accumulation of items at the top of the conveyor device 1, thus reducing its transport speed. The device improves its practicality by preventing the omission of uncoded items when moving too fast. Since the conveyor 1 does not immediately stop operating during shutdown, subsequent items are conveyed to the clamping mechanism 3 by the inertia of the conveyor 1. Electrical connections are then established between the two sets of infrared detectors 505 and the control terminal of the clamping mechanism 3, allowing the clamping mechanism 3 to clamp and position the items upon arrival. This minimizes the risk of errors in coding caused by the clamping mechanism 3's inability to adjust the positioning of items conveyed at the top of the conveyor 1.
[0033] Simultaneously, by positioning two sets of pressure sensors 4 between the two sets of positioning plates 301 and the contact surfaces on both sides of the conveyed item, when the adjacent sides of the two sets of positioning plates 301 respectively abut against the left and right sides of the conveyed item, the two sets of pressure sensors 4 are triggered to shut down the two sets of electric telescopic rods 303. This minimizes the risk of excessive compression of the conveyed item during the clamping and positioning process by the two sets of positioning plates 301, thus preventing damage to the conveyed item. The above describes and illustrates 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 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.
