Description

Technical Field

[0001] This utility model relates to the technical field of carton board printing equipment, specifically to a carton board printing feeding component, used to realize automatic support, gripping, correction and limiting and traction conveying of carton boards during the carton board printing process. Background Technology

[0002] In corrugated board printing production, the feeding assembly is one of the key pieces of equipment, and its performance directly affects printing efficiency and quality. Existing corrugated board feeding assemblies typically include a frame, a material support mechanism, and a gripping mechanism, but in practical applications, the following problems exist: Inaccurate control of cardboard height leads to material handling failures: Existing feeding components often use fixed height or simple lifting methods for their material support mechanisms, lacking an effective travel limitation mechanism. During the stacking of cardboard boxes, the height of the top cardboard box may exceed the effective adsorption range of the gripping mechanism (such as a suction cup), causing the suction cup to be unable to reliably adsorb the cardboard box, resulting in material handling interruption or failure, and affecting the continuity of material supply. Utility Model Content

[0003] In order to overcome the problem that the suction cup cannot reliably pick up materials due to the inaccurate control of the stacking height of the cardboard in the existing cardboard board feeding assembly, which affects the continuity of material supply, this utility model provides a cardboard board printing feeding assembly. By setting a pressure plate to limit the maximum stroke of the cardboard board, and coordinating with the material support, suction feeding, limiting and traction components, reliable material picking and continuous and stable material supply can be achieved.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a carton board printing feeding assembly, including a frame, a material support assembly provided on the upper part of the frame for supporting and vertically lifting the carton board; a feeding assembly provided on the upper part of the frame opposite to the material support assembly for gripping and conveying the carton board by suction; a limiting assembly provided on the upper part of the frame for adjusting the lateral spacing to laterally correct and limit the carton board on the material support assembly; a traction assembly for traction and conveying the carton board conveyed by the feeding assembly; and a pressure plate fixedly provided on the upper part of the frame, the lower surface of which is lower than the lower surface of the suction cup of the feeding assembly for limiting the maximum stroke of the carton board.

[0005] The aforementioned cardboard board printing feeding assembly includes a support plate, a first screw, a first screw sleeve, and a first motor. The support plate is horizontally arranged to support the cardboard board. The first screw is vertically arranged and rotatably connected to the frame. The first screw sleeve meshes with the first screw and is connected to the support plate. The first motor drives the first screw to rotate via gears and a chain.

[0006] In the aforementioned cardboard printing feeding assembly, the first screw sleeve is fixedly connected to the frame plate by bolts.

[0007] The aforementioned cardboard printing feeding assembly includes a first cylinder, a first strip, a second cylinder, and a second strip; the first cylinder is vertically fixed on the frame, and its cylinder rod is connected to the first strip; the second cylinder is horizontally installed below the first strip, and its cylinder rod is connected to the second strip equipped with the suction cup.

[0008] In the aforementioned cardboard printing feeding assembly, the first strip forms a vertical sliding pair with the machine frame via a first slider and a first slide rail.

[0009] In the aforementioned cardboard printing feeding assembly, the second strip forms a horizontal sliding pair with the first strip via a second slider and a second slide rail.

[0010] The aforementioned cardboard printing feeding assembly includes a limiting component comprising a third strip, a second screw, and a second screw sleeve; the third strip is symmetrically arranged on both sides of the material support assembly; the second screw is arranged laterally and has reverse threads at both ends; the second screw sleeve meshes with the second screw and is connected to the third strip.

[0011] In the aforementioned cardboard printing feeding assembly, the second screw is connected as a whole through a coupling to achieve synchronous rotation.

[0012] In the aforementioned cardboard printing feeding assembly, the two second screws on the same side rotate synchronously via belt drive.

[0013] The aforementioned cardboard printing feeding assembly includes a traction component comprising a cross brace, a pressure roller, a support roller, and a second motor; the cross brace is fixed to the frame; the pressure roller is disposed below the cross brace; and the support roller is disposed below the pressure roller and is connected to the second motor for transmission.

[0014] The beneficial effects of this utility model are: 1. By setting a fixed pressure plate and cooperating with a liftable material support component, the maximum lifting position of the carton board can be automatically limited, ensuring that the top carton board is always within the effective adsorption range of the suction cup, thereby ensuring the reliability of material picking.

[0015] 2. The material support assembly, feeding assembly, limiting assembly, and traction assembly work together to realize an automated process from supporting, gripping, and correcting the deviation of the carton board to traction and conveying. While ensuring stable material picking, it effectively improves the continuity and efficiency of the entire material feeding process.

[0027] This application relates to a cardboard printing feed assembly 3, such as... Figure 1-8As shown, the carton board printing feeding assembly 3 of this embodiment mainly includes a frame 1 that serves as a basic support. Different components are rationally arranged on the upper part of the frame 1 according to functional requirements. The frame 1 serves as the basic support structure for the entire feeding assembly 3. One end of its upper part is equipped with a material support assembly 2 that can be vertically raised and lowered to support the carton board, and the other end is equipped with a feeding assembly 3 that uses suction to grip and feed the carton board. Simultaneously, the upper part of the frame 1 also includes a limiting assembly 4 with adjustable lateral spacing to perform lateral correction and limiting operations on the carton board above the material support assembly 2, and a traction assembly 5 that can pull and convey the carton board delivered by the feeding assembly 3. Furthermore, to prevent the horizontal height of the topmost surface of the carton board on the shelf 21 from exceeding the lower surface of the suction cup 39, thus preventing the suction cup 39 from adsorbing and picking up the carton board, a pressure plate 6 is added to the upper part of the frame 1 to limit the highest travel point of the carton board. The lower surface of the pressure plate 6 is slightly lower than the lower surface 5 of the suction cup 39. 10mm.

[0028] The material support assembly 2 includes a frame plate 21, a first screw 22, a first screw sleeve 23, a gear 24, and a first motor 25. The frame plate 21 is horizontally arranged inside the rear side of the frame 1, providing a support surface for the cardboard. The first screw 22 is vertically arranged around the frame plate 21. A first screw sleeve 23, adapted to the first screw 22, is provided at the bottom of the frame plate 21. The first screw sleeve 23 is connected to the frame plate 21 by bolts to ensure a stable connection. The first screw 22 is connected to the frame 1 by a bearing seat, allowing the first screw 22 to rotate flexibly relative to the frame 1. When the height of the frame plate 21 needs to be adjusted, the first motor 25 is started. 5 is fixed to the upper part of the frame 1 by bolts. The output end of the first motor 25 and the end of the first screw 22 are both keyed to the gear 24. The gear 24 is fitted with a transmission chain. When the first motor 25 runs, it drives the first screw 22 to rotate through the chain. Since the first screw sleeve 23 meshes with the first screw 22, the rotation of the first screw 22 will drive the first screw sleeve 23 to move up and down, thereby driving the frame plate 21 to move back and forth along the vertical direction of the frame 1. During the process of the frame plate 21 lifting the carton board, when the uppermost surface of the carton board abuts against the lower surface of the pressure plate 6, since the position of the pressure plate 6 is fixed and its lower surface is slightly lower than the lower surface of the suction cup 39 by 5-10mm, the frame plate 21 stops lifting the carton board to prevent the carton board from being too high and causing the suction cup 39 to be unable to pick it up. As the carton board is gradually removed by the suction cup 39, the frame plate 21 will lift it up again to ensure the continuity of material supply.

[0029] The feeding assembly 3 includes a first cylinder 31, a first strip 32, a first slider 33, a first slide rail 34, a second cylinder 35, a second strip 36, a second slider 37, a second slide rail 38, and a suction cup 39. The first cylinder 31 is vertically arranged on the top of the frame 1, and its cylinder body is fixedly connected to the frame 1 by bolts to ensure the stability of the first cylinder 31 during operation. When it is necessary to perform a cardboard board gripping operation, the cylinder rod of the first cylinder 31 retracts, driving the first strip 32, which is bolted to the end of the cylinder rod, to move downward. The first slider 33 is vertically arranged at both ends of the length direction of the first strip 32 and is connected to it by bolts. The upper part of the frame 1 is vertically arranged with a first slide rail 34 that matches the first slider 33. Driven by the first cylinder 31, the first strip 32 moves vertically back and forth along the surface of the first slide rail 34 with the help of the first slider 33, ensuring the smoothness of the movement of the first strip 32.

[0030] A second cylinder 35 is horizontally arranged at the lower part of the first plate 32. The cylinder body of the second cylinder 35 is fixedly connected to the first plate 32 by bolts. The lower part of the cylinder rod of the second cylinder 35 is bolted to a horizontally arranged second plate 36. Multiple suction cups 39 for adsorbing one end of the cardboard are evenly and spaced along the length of the second plate 36. When the first plate 32 descends to a suitable position, the second cylinder 35 is activated, its cylinder rod extends, and drives the second plate 36 to move downward, so that the suction cups 39 contact the surface of the cardboard and adsorb. To enhance the load-bearing capacity of the second strip 36, the upper part of the second strip 36 has two symmetrically arranged second sliders 37 bolted to it and arranged along its width. The first strip 32 has a symmetrically arranged second slide rail 38 adapted to the second sliders 37. When the second cylinder 35 drives the second strip 36 to move horizontally, the second strip 36 moves horizontally linearly along the surface of the second slide rail 38 with the help of the second sliders 37, ensuring that the second strip 36 can stably drive the adsorbed cardboard to move horizontally.

[0031] The limiting assembly 4 includes a second screw 41, a third strip 42, and a second screw sleeve 43. The third strip 42 is vertically and symmetrically arranged on both sides of the width direction of the frame plate 21, and is used to limit the lateral movement of the carton board. The second screw 41 is symmetrically arranged at the upper and lower ends of the third strip 42. The second screw 41 is composed of two screws with opposite and mirror-symmetrical threads, and the screws are connected to each other for synchronous rotation through a coupling. The second screw sleeve 43, which is adapted to the second screw 41, is arranged on the upper part of the third strip 42. The second screw sleeve 43 is connected to the third strip 42 by bolts. When it is necessary to adjust the spacing between the two third strips 42 to accommodate cardboard boxes of different widths, the second screw 41 is rotated. Since the two screw threads of the second screw 41 are opposite and rotate synchronously through the coupling, the second screws 41 at both ends of the upper length direction of the third strip 42 are synchronously powered by the belt. This causes the second threaded sleeves 43 at both ends of the length direction of the two third strips 42 to be driven by the rotation of the second screw 41, thereby causing the two third strips 42 to move towards or away from each other, thus achieving the width adaptation operation for cardboard boxes of different widths.

[0032] The traction assembly 5 includes a cross brace 51, pressure rollers 52, idler rollers 53, a second motor 54, and a support plate 55. The cross brace 51 is horizontally arranged inside the frame 1, and its two ends are connected to the frame 1 by bolts, providing a mounting base for the pressure rollers 52. Multiple pressure rollers 52 are spaced apart below the cross brace 51 to abut against the upper surface of the cardboard box. The idler rollers 53 are arranged directly below the pressure rollers 52, and their two ends along their length are connected to the frame 1 by bearing seats, ensuring that the idler rollers 53 can rotate flexibly. The upper part of the frame 1 is also equipped with a second motor 54 connected to the idler roller 53 via belt drive. When the feeding component 3 grabs the carton board and sends it to the traction component 5, one end of the carton board is located between the pressure roller 52 and the idler roller 53. The second motor 54 is started, and the second motor 54 drives the idler roller 53 to rotate via belt drive. When the idler roller 53 rotates, the pressure roller 52 abuts against the upper surface of the carton board, clamping the carton board and driving the carton board away from the frame 1, thus realizing a stable feeding operation of the carton board.

[0033] Through the coordinated work of the above components, the carton board printing feeding component 3 of this embodiment can efficiently and stably complete operations such as supporting, gripping, correcting and limiting the carton board and traction conveying, so as to meet the feeding needs of carton board printing production.
