Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, specifically a packaging box marking machine with a centering structure. Background Technology

[0002] In industries such as logistics and product packaging, packaging boxes serve as the core carriers for product storage and transportation. Their surfaces must be marked with key information such as product details, logistics codes, and anti-counterfeiting labels. The marking process is a crucial step in packaging box production. With increasing industry demands for standardization and informatization in packaging, the market is placing higher demands on the accuracy, efficiency, and product integrity of packaging box marking. This is especially true in mass production scenarios, where rapid positioning and accurate marking of packaging boxes are essential to ensure smooth subsequent logistics and information traceability.

[0003] Currently, marking on packaging boxes mainly relies on traditional marking machines. Existing traditional marking machines use a single clamping plate or manual positioning, which can only limit the packaging box on one or both sides. They cannot achieve full centering in all four directions, which makes the packaging box prone to shifting or tilting, affecting the accuracy of the marking position.

[0004] Therefore, it is necessary to design a new type of packaging box marking machine with a centering structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a packaging box marking machine with a centering structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging box marking machine with a centering structure, comprising a marking machine body, a processing platform on the body, a centering structure on the processing platform, the centering structure comprising two clamping plates, a bidirectional screw at the bottom of the processing platform, a sliding groove on the processing platform, a slider slidably connected in the sliding groove, the slider being fixedly connected to a side plate, and the bidirectional screw being screwed to the two sliders respectively.

[0007] Preferably, the clamping plate has side plates at both ends, and the side plates have through grooves. A rotating shaft is rotatably connected in the through grooves, and the rotating shaft is fixed to one end of the side plate.

[0008] Preferably, a first gear is fixed in the middle of the rotating shaft, a second gear is provided on one side of the side plate, and racks are slidably connected to both sides of the second gear, with the racks meshing with the first gear.

[0009] Preferably, a protective cover is provided on one side of the side plate, and the gear is rotatably connected to the protective cover.

[0010] Preferably, the clamping plate has an opening in the middle, and a plurality of guide rollers are provided at the opening.

[0011] Preferably, the other end of the side plate is provided with a second guide roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a dual positioning system is formed by setting a primary centering structure of "bidirectional screw + double clamping plate" and a secondary centering structure of "gear-rack transmission + rotatable side plate + guide roller II". The primary centering achieves initial clamping and limiting on both sides of the packaging box. The secondary centering uses the synchronous angle adjustment of the four side plates and the guide roller II to clamp the packaging box in the front, back, left and right directions. The guide roller I in the middle of the clamping plate reduces the sliding resistance of the packaging box, allowing the packaging box to be slightly adjusted between the clamping plates during the secondary centering. This effectively solves the problems of marking position deviation and skewing of characters caused by centering deviation in traditional marking machines. Attached Figure Description

[0020] 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.

[0021] All electronic components in this application are controlled by an external controller, and all electrical appliances in this application are powered by a stable power supply that is compatible with them.

[0022] Example 1 Please refer to Figure 1-6 As shown, this utility model provides a packaging box marking machine with a centering structure, including a marking machine body 1, a processing platform 2 on the body 1, a centering structure on the processing platform 2, the centering structure including two clamping plates 3, a bidirectional screw 4 at the bottom of the processing platform 2, a sliding groove 5 on the processing platform 2, a slider 6 slidably connected in the sliding groove 5, the slider 6 being fixedly connected to a side plate 7, and the bidirectional screw 4 being screwed to the two sliders 6 respectively.

[0023] The main body 1 is a commonly used packaging box marking machine with a centering structure. The processing platform 2 is fixed on the main body 1. The centering structure can fix the packaging box to be marked. The centering structure includes two clamping plates 3 connected by a bidirectional screw 4. The two clamping plates 3 are close to each other to clamp the packaging box. The bidirectional screw 4 is installed at the bottom of the processing platform 2 through a shaft seat. A slide groove 5 is opened on the processing platform 2. A slider 6 is slidably connected to the slide groove 5. The top of the slider 6 is fixed to the clamping plate 3. The middle and lower part of the slider 6 is screwed to the bidirectional screw 4. When the bidirectional screw 4 rotates, the two clamping plates 3 will move closer or further apart to clamp the packaging box to be marked.

[0024] Specifically, the clamping plate 3 has side plates 7 at both ends, and the side plates 7 have through grooves 8. A rotating shaft 9 is rotatably connected in the through grooves 8, and the rotating shaft 9 is fixed to one end of the side plate 7. The other end of the side plate 7 has a guide roller 15. The side plates 7 are located on both sides of the clamping plate 3, the through grooves 8 are opened at the ends of the side plates 7, the rotating shaft 9 is fixed to the side plates 7, and the guide roller 15 is rotatably connected to one end of the side plates 7. The side plates 7 can rotate a certain angle in the through grooves 8 through the rotating shaft 9, which can easily adjust the angle of the side plates 7. When the guide roller 15 contacts the packaging box, multiple guide rollers 15 can push the packaging box and center it, which can facilitate precise adjustment of the marking position.

[0025] The rotating shaft 9 has a gear 10 fixed in the middle, and a gear 11 is provided on one side of the side plate 7. Racks 12 are slidably connected to both sides of the gear 11, and the racks 12 mesh with the gear 10. A protective cover 13 is provided on one side of the side plate 7. The gear 11 is rotatably connected to the protective cover 13. The gear 10 is fixed in the middle of the rotating shaft 9, and the gear 11 is rotatably connected to the outer wall of the side plate 7. The racks 12 are slidably connected to the outer wall of the side plate 7. The two racks 12 on the same side mesh with the gear 11. When the gear 11 rotates, it can push the two racks 12 to move closer or further away synchronously. When the racks 12 move, they can drive the side plate 7 to rotate at a certain angle through the gear 10. The protective cover 13 protects the gear 11 and racks 12, reducing external influences.

[0026] Based on the above embodiment, specifically, the clamping plate 3 has an opening in the middle, and a plurality of guide rollers 14 are provided at the opening. The opening is opened on the clamping plate 3, and the guide rollers 14 are rotatably connected to the inside of the opening. The guide rollers 14 enable the packaging box to slide between the two clamping plates 3, reducing the wear when the packaging box is centered.

[0027] Working principle: In use, the packaging box to be marked is first conveyed between two clamping plates 3. Then, the two clamping plates 3 are driven to move closer to each other by the bidirectional screw 4 until multiple guide rollers 14 on the two clamping plates 3 clamp the two sides of the packaging box. Then, the gear 11 rotates. The rotation of gear 11 drives the two racks 12 to slide synchronously. The racks 12 drive gear 10 to rotate, which drives the side plates 7 on both sides to rotate until the guide rollers 15 at the ends of the four side plates 7 clamp the packaging box. At the same time, due to the presence of guide rollers 14, the packaging box can be finely adjusted between the two clamping plates 3 when the guide rollers 15 clamp the packaging box, which facilitates the centering of the packaging box and improves the accuracy of marking.

[0028] More specifically, a conveyor belt 16 is provided on the processing platform 2 and located between the two clamping plates 3, which facilitates the transport of packaging boxes.
