Description

Technical Field

[0001] This utility model belongs to the field of barcode labeling machine technology, specifically relating to the barcode positioning mechanism of an automatic barcode labeling machine. Background Technology

[0002] An automatic labeling machine is a device that affixes rolls of paper or foil labels to specified packaging containers or products. The labels have adhesive backing and are arranged regularly on a glossy backing paper; the labeling machine's peeling mechanism automatically removes them. Labeling can perform various operations, including flat labeling, single-sided or multi-sided labeling of packaging, cylindrical labeling, partial or full coverage of cylindrical surfaces, and labeling of recessed and corner areas.

[0003] Existing automatic barcode labeling machines still have some shortcomings. Most of them lack accuracy in positioning barcodes. Typically, after the barcode is drawn out, it passes through a barcode sensor, which can detect the position of the barcode to achieve the purpose of barcode positioning. After positioning, the barcode is peeled off by a peeling plate under the transport roller and pressure roller. When the peeling plate peels off the barcode, the barcode may tilt, resulting in inaccurate labeling and posing a safety hazard. To address this, we propose a barcode positioning mechanism for automatic barcode labeling machines. Utility Model Content

[0004] The purpose of this invention is to provide a barcode positioning mechanism for an automatic barcode labeling machine, so as to solve the problem of insufficient accuracy in barcode positioning mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a barcode positioning mechanism for an automatic barcode labeling machine, comprising a base and a conveyor belt. The conveyor belt is mounted on the top of the base, and a limit plate is fixed to one end of the conveyor belt. Four guide rods are fixed to one side of the base, and a sliding block is slidably connected to the middle of each guide rod. A mounting frame is fixed to one side of the sliding block, and a peeling plate is fixed to one end of the mounting frame. A fixing frame is fixed to one side of the base, and a telescopic rod is mounted at the bottom of the fixing frame. A spring is sleeved on the surface of the telescopic rod, and a connecting frame is fixed to one end of the telescopic rod. A pressure roller is rotatably connected to the inner side of the connecting frame. A support frame is fixed to one side of the base, and a camera is mounted at the bottom of the support frame. An alarm is mounted at the top of the support frame.

[0006] Preferably, the sliding block is threaded with a threaded rod at its middle, and a turntable is fixed to one end of the threaded rod.

[0007] Preferably, a roll barcode is rotatably connected to one end of the mounting frame, a first transport roller is rotatably connected to the inner side of the mounting frame, and a second transport roller is rotatably connected to the middle of the mounting frame.

[0008] Preferably, a first support roller is rotatably connected inside the mounting frame, and a pressure roller is also provided on the inner side of the mounting frame, with the pressure roller and the mounting frame rotatably connected.

[0009] Preferably, a barcode positioning sensor is installed inside the mounting frame, a second support roller is rotatably connected to the bottom of the mounting frame, and two guide rollers are rotatably connected to the bottom of the mounting frame.

[0010] Preferably, a storage rod is rotatably connected to the bottom inner side of the mounting bracket, a motor is installed on one side of the mounting bracket, and a control center is fixed on one side of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The system utilizes guide rods, sliding blocks, mounting frames, peeling plates, fixing frames, and support frames to achieve barcode positioning. After the barcode is peeled off, it moves to the bottom of the pressure roller as the product is transported. When the product moves to the barcode's position, the pressure roller squeezes the barcode, ensuring it adheres stably to the product surface and preventing tilting. The telescopic rod and spring cushion the pressure roller, preventing damage to the product. After barcode application, the product moves to the bottom of the camera, which takes a picture to check if the barcode is accurately positioned. If a deviation occurs, the control center activates an alarm to alert staff and improve safety.

[0012] 2. The height of the mounting frame can be adjusted by the threaded rod and turntable, and the labeling height can be adjusted according to different products, making it more convenient to use. The barcode positioning sensor can perform preliminary detection of the position of the barcode as soon as it is pulled out. The second support roller can support the barcode waste paper, making it easy to collect the waste paper. The guide roller can press the waste paper. Attached Figure Description

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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a barcode positioning mechanism for an automatic barcode labeling machine, including a base 1 and a conveyor belt 2. The conveyor belt 2 is installed on the top of the base 1, and a limit plate 3 is fixed to one end of the conveyor belt 2. Four guide rods 4 are fixed to one side of the base 1. A sliding block 5 is slidably connected to the middle of the guide rods 4. A mounting frame 6 is fixed to one side of the sliding block 5. A peeling plate 7 is fixed to one end of the mounting frame 6. A fixing frame 8 is fixed to one side of the base 1. A telescopic rod 9 is installed at the bottom of the fixing frame 8. A spring 10 is sleeved on the surface of the telescopic rod 9. A connecting frame 11 is fixed to one end of the telescopic rod 9. A pressure roller 12 is rotatably connected to the inner side of the connecting frame 11. A support frame 13 is fixed to one side of the base 1. A camera 14 is installed at the bottom of the support frame 13. An alarm 15 is installed at the top of the support frame 13. The guide rod 4, sliding block 5, mounting bracket 6, peeling plate 7, fixing bracket 8, and support bracket 13 enable the positioning function of the barcode. After the barcode is peeled off, it moves to the bottom of the pressure roller 12 as the barcode is transported. When the product moves to the position of the barcode, the pressure roller 12 will squeeze the barcode to make it stably adhere to the product surface, preventing the barcode from tilting. The telescopic rod 9 and spring 10 can buffer the pressure roller 12 to avoid damage to the product. After the barcode is affixed, the product moves to the bottom of the camera 14, which will take a picture to check whether the barcode is accurately affixed to the required position on the product. If a deviation occurs, the control center 29 will activate the alarm 15 to remind the staff to deal with it in time, effectively improving safety.

[0017] Specifically, the sliding block 5 is threadedly connected to a threaded rod 16 in the middle, and a turntable 17 is fixed to one end of the threaded rod 16. The height of the mounting bracket 6 can be adjusted by the threaded rod 16 and the turntable 17. The labeling height can be adjusted according to the different products, making it more convenient to use.

[0018] Specifically, a roll barcode 18 is rotatably connected to one end of the mounting frame 6, a first transport roller 19 is rotatably connected to the inner side of the mounting frame 6, and a second transport roller 20 is rotatably connected to the middle of the mounting frame 6. The transport of the barcode is achieved through the first transport roller 19 and the second transport roller 20.

[0019] Specifically, the mounting frame 6 is rotatably connected to a first support roller 21, and the inner side of the mounting frame 6 is also provided with a pressure roller 22. The pressure roller 22 and the mounting frame 6 are rotatably connected. The barcode can be pressed by the first support roller 21 and the pressure roller 22, thereby cooperating with the peeling plate 7 to complete the peeling of the barcode.

[0020] Specifically, a barcode positioning sensor 23 is installed inside the mounting frame 6. A second support roller 25 is rotatably connected to the bottom of the mounting frame 6, and a guide roller 26 is rotatably connected to the bottom of the mounting frame 6. There are two guide rollers 26. With the barcode positioning sensor 23, the position of the barcode can be initially detected when it is first pulled out. The second support roller 25 can support the barcode waste paper, making it easy to collect the waste paper. The guide roller 26 can press the waste paper.

[0021] Specifically, a storage rod 27 is rotatably connected to the bottom inner side of the mounting frame 6, a motor 28 is installed on one side of the mounting frame 6, and a control center 29 is fixed on one side of the base 1. When the motor 28 is started, the storage rod 27 is rotated, thus realizing the function of automatic labeling.

[0022] In this embodiment, when using the device, the motor 28 is started, driving the collecting roller 27 to rotate, thereby collecting the barcode waste paper and simultaneously drawing the barcode from the roll barcode 18. The barcode passes over the surface of the first transport roller 19, then around the inside of the second transport roller 20, so that the barcode passes over the surface of the first support roller 21 and passes through the bottom of the pressure roller 22. The barcode is peeled off by the peeling plate 7 as it moves past. As the barcode is transported, the peeled barcode moves to the bottom of the pressure roller 12. When the product moves to the position of the barcode, the pressure roller 12 squeezes the barcode. This ensures the barcode adheres stably to the product surface, preventing it from tilting. The telescopic rod 9 and spring 10 cushion the pressure roller 12, preventing damage to the product. After barcode application, the product moves to the bottom of the camera 14, where it takes a picture to check if the barcode is accurately placed in the desired position. If a deviation occurs, the control center 29 activates the alarm 15 to alert staff and improve safety. The waste paper from which the barcode is peeled off passes through the second support roller 25 and guide roller 26, and is eventually collected on the surface of the collection roller 27.
