Description

Technical Field

[0001] This utility model relates to the field of cardboard box cutting, specifically a positioning mechanism for a cardboard box cutting device. Background Technology

[0002] A positioning mechanism for a carton cutting device is a device that fixes the carton during the cutting process to prevent it from moving.

[0003] Patent CN221835036U discloses a carton manufacturing cutting and edge-pressing positioning device, belonging to the field of positioning device technology. It includes a frame with a cutting opening on one side. A blade cutting device is installed inside the cutting opening. A visual recognition positioning and gripping mechanism is installed at the top of the frame. In the modern carton processing industry, efficient and precise cutting is a key link in ensuring product quality and production efficiency. The positioning mechanism in the carton cutting device, as a core component, directly affects the accuracy and stability of carton cutting. Currently, metal pressure plates are a common choice for positioning mechanisms due to their significant advantages such as high strength, good stability, wear resistance, and excellent processing performance. With its high strength, the metal pressure plate can maintain structural stability and avoid deformation when fixing the carton under significant pressure; its good wear resistance allows it to maintain positioning accuracy for a long time under conditions of frequent contact and friction with the carton, ensuring accurate cutting dimensions and greatly meeting the stringent requirements of industrial production for carton consistency and standardization. However, with the increasing complexity of cardboard box manufacturing processes, corrosive chemicals such as inks and adhesives are widely used in the production of cardboard boxes. During the cutting and positioning process, the metal pressure plate frequently comes into contact with the cardboard box, and these corrosive substances easily remain on the pressure plate surface. If not cleaned in time, the residue will continue to corrode the pressure plate, causing the contact surface of the metal pressure plate to gradually become rough. During the positioning process, the rough pressure plate surface will cause scratches, indentations, and other damage to the cardboard box surface, seriously affecting the appearance quality of the cardboard box and leading to a decrease in the product qualification rate.

[0004] What's even more challenging is that cardboard box cutting is usually a large-scale production operation. During the production process, the pressure plate comes into contact with a large number of cardboard boxes, and corrosive substances remain quickly. If manual cleaning is used regularly, it will consume a lot of manpower and time costs, which will not only increase the company's production costs, but also cause a significant reduction in production efficiency due to downtime for cleaning, making it difficult to meet the needs of modern large-scale and high-efficiency production. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning mechanism for a carton cutting device.

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.

[0024] Please see Figures 1-5 The present invention provides a technical solution: a positioning mechanism for a carton cutting device, comprising a base 1, a first support plate 2 disposed above the base 1, a first cylinder 3 fixedly connected to the upper surface of the first support plate 2, a first air rod 4 fixedly connected to the output end of the first air rod 3, a cutting blade 5 fixedly connected to the lower end of the first air rod 4, a pushing mechanism 6 disposed on one side of the base 1, and an elastic mechanism 7 disposed on the outer side of the first air rod 4.

[0025] The pushing mechanism 6 includes a third support plate 601 fixedly connected to one side of the base 1. A second cylinder 602 is fixedly connected to the upper side of the third support plate 601. A second air rod 603 is fixedly connected to the output end of the second cylinder 602. A first slide groove 604 is provided inside one end of the second air rod 603. The width of the first slide groove 604 near the second cylinder 602 is greater than the width of the first slide groove 604 away from the second cylinder 602, and the inner side of the first slide groove 604 fits against the inner side of the first slider 610, so that the first... The slider 610 will not move out of the inner side of the first groove 604. A second support plate 605 is fixedly connected to the other side above the third support plate 601. The second support plate 605 has a first guide groove 606 inside. The first guide groove 606 has a horizontal straight-line shape, and the first guide groove 606 and the guide rod 611 are fitted with a clearance fit, so that the guide rod 611 will not move up and down when it moves inside the first guide groove 606. The end of the first guide groove 606 away from the second cylinder 602 is connected to the second guide groove. 607. The upper and lower ends of the second guide groove 607 are both horizontal straight lines, and the connection between the upper and lower ends of the second guide groove 607 is an inclined straight line. The upper width of the second guide groove 607 is greater than the lower width of the second guide groove 607. A groove 608 is provided connecting the first guide groove 606 and the second guide groove 607. A baffle 609 is vertically slidably connected to the inner side of the groove 608. A first slider 610 is provided inside the first sliding groove 604. A slider 610 is fixedly connected to the first slider 610 inside the first guide groove 606. A cleaning plate 612 is fixedly connected to the side of the guide rod 611 and the first slider 610 away from the second cylinder 602. The first support plate 2 has a hole 613 in the middle for nesting the cleaning plate 612. The first guide groove 606 has a horizontal straight shape and the first guide groove 606 and the guide rod 611 are fitted with a clearance fit. The outer side of the baffle 609 fits against the inner side of the groove 608 and the outer shape of the baffle 609 is a parallelogram. The vertical width of the hole 613 is greater than the vertical width of the cleaning plate 612.

[0026] The elastic mechanism 7 includes an elastic telescopic rod 701 fixedly connected to the outside of the first gas rod 4. The lower end of the elastic telescopic rod 701 is fixedly connected to a pressure plate 702. The inner sides of the third support plate 601 are provided with second sliding grooves 703. The inner side of the second sliding groove 703 is provided with a second slider 704 fixedly connected to the pressure plate 702. The central axis of the second sliding groove 703 is perpendicular to the upper surface of the base 1.

[0027] Using an external device, place the cardboard box to be cut in a suitable position on the base 1. Activate the first cylinder 3, which drives the first air rod 4 and the cutting blade 5 downwards. This causes the first air rod 4, the elastic telescopic rod 701, and the pressure plate 702 to move downwards, so that the lower surface of the pressure plate 702 first contacts and presses against the upper surface of the cardboard box. As the pressure plate 702 moves downwards, it drives the second slider 704 downwards. After the lower surface of the second slider 704 contacts the upper surface of the second slide groove 703, the pressure plate 702 stops moving downwards, and cutting begins. The blade 5 can continue to move downwards to complete the cutting action. The first cylinder 3 is activated, driving the first air rod 4 and the cutting blade 5 upwards, causing the pressure plate 702 to reset. At this time, the second cylinder 602 is activated, driving the second air rod 603 to move towards the cutting blade 5. This causes the cleaning plate 612, guide rod 611, and first slider 610 to move towards the cutting blade 5. Because the first guide groove 606 has a horizontal straight-line shape and the first guide groove 606 and guide rod 611 are in a clearance fit, the cutting blade... 5. First, the movement stabilizes at the bottom for a period of time. When it reaches the position of the baffle 609, because both the upper and lower ends of the second guide groove 607 are horizontal straight lines, and the connecting points between the upper and lower ends of the second guide groove 607 are inclined straight lines, and the upper width of the second guide groove 607 is greater than the lower width of the second guide groove 607, the outer side of the baffle 609 fits against the inner side of the groove 608, and the external structure of the baffle 609 is a parallelogram, the guide rod 611 moves along the inclined side of the baffle 609 to the position of the second guide groove 609. The inner side of the second guide groove 607 allows the cleaning plate 612, guide rod 611, and first slider 610 to move upwards, contacting the lower surface of the pressure plate 702, then moving laterally to clean the dirt, and then moving downwards. After cleaning, the second cylinder 602 is activated to drive the cleaning plate 612, guide rod 611, and first slider 610 to move back, causing the guide rod 611 to push the baffle 609 upwards, so that the guide rod 611 returns to the inner side of the first guide groove 606. This automated cleaning method saves manpower.

[0028] Because the cleaning plate 612 contacts the lower surface of the pressure plate 702, it moves laterally for cleaning, then moves downwards, and finally moves back down from below. This avoids the cleaning plate 612 repeatedly cleaning the pressure plate 702, thus preventing secondary pollution. This allows the pressure plate 702 to achieve a unidirectional cleaning effect, thereby improving the cleaning effect.
