Description

Technical Field

[0001] This utility model relates to the field of printing press wall panel production technology, specifically to a printing press wall panel hanging suction cup. Background Technology

[0002] The overall structure of the printing press is based on two wall panels as supporting components. A large number of shaft and roller parts are installed between the two wall panels, allowing the continuous printing substrates to pass through the orderly arranged shafts, rollers and cylinders. Under the premise of tension control, paper feeding, alignment, water supply, ink supply, printing, cutting, paper feeding, paper handover, coding, drying, cooling, varnishing and various other processes to ensure the automatic completion of printing, the assembly quality and precision of the wall panels remain stable.

[0003] When printing press wall panels are processed, they are lifted onto the machine tool using a permanent magnet lifter. Before processing, the wall panels are generally regular cuboids. When the permanent magnet lifter places the wall panels, the operator usually determines the center point of the wall panel. During lifting, the center of gravity may shift or tilt, requiring manual support to maintain balance. Therefore, this application designs a printing press wall panel lifting suction cup for center positioning and lifting when facing regular cuboid wall panels, thus solving this technical defect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a suction cup for hanging wall panels of printing machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suction cup for hanging wall panels of a printing machine, including a central positioning seat, with hinged seats at the four corners of the bottom of the central positioning seat, and connecting rods hinged on the hinged seats. Hollow rods are hinged between the connecting rods on the left and between the connecting rods on the right. Rectangular moving rods slide inside both ends of the hollow rods, and a permanent magnet lifter is vertically provided at the lower end of the other end of the rectangular moving rod.

[0006] The hollow rod is equipped with an adjustment component for adjusting the movement of the rectangular moving rod.

[0007] Using the above technical solution, the adjusting component is adjusted according to the length of the cuboid wall panel, driving the rectangular moving rod to move inside the hollow rod, so that the permanent magnet lifters move outward synchronously, making the distance between the two permanent magnet lifters equal to the distance between the cuboid wall panels. After adjustment, according to the width of the cuboid wall panel, the adjusting connecting rod rotates on the hinge seat on the central positioning seat, changing the angle between the two adjusting connecting rods and the central positioning seat. This angle change ensures that the width of the two permanent magnet lifters is equal to the width of the cuboid wall panel, thus facilitating the attachment and fixing of the four permanent magnet lifters to the four corners of the cuboid wall panel surface, ensuring that the edges are aligned. This ensures that the central positioning seat is centered on the cuboid wall panel, guaranteeing overall stability and preventing deviation during hoisting when the central positioning seat is connected.

[0008] As a preferred embodiment of this utility model, a lifting ring is provided at the upper center of the central positioning seat.

[0009] By adopting the above technical solution, the lifting ring is designed to facilitate the connection of the lifting rope lock of the lifting equipment.

[0010] In a preferred embodiment of this invention, the connecting rod rotates left and right on both the hinge seat and the hollow rod.

[0011] As a preferred technical solution of this utility model, the adjustment component is mounted on the mounting base at the front and rear ends of the hollow rod. The surface of the front mounting base is provided with a rotating shaft seat, and a bidirectional threaded rod that passes through the rear mounting base is rotatably mounted on the rotating shaft seat.

[0012] The bidirectional threaded rod has a forward threaded groove and a reverse threaded groove on both sides based on central symmetry. Both the forward and reverse threaded grooves are threaded with threaded seats. The threaded seats are located outside the bidirectional threaded rod. Each of the two threaded seats is connected to the permanent magnet lifter on both sides by a connecting rod.

[0013] As a preferred embodiment of this utility model, the other end of the bidirectional threaded rod is provided with a handheld rotating head.

[0014] By adopting the above technical solution, the bidirectional threaded rod is rotated on the rotating shaft seat on the mounting base by rotating the hand-held rotating head. At the same time, the forward and reverse threaded grooves on the bidirectional threaded rod are threaded to the threaded seat, and the hollow rod limits the linear movement of the rectangular moving rod. This ensures that when the bidirectional threaded rod rotates, it drives the rectangular moving rod connected to the threaded seat and the connecting rod to move, thereby driving the permanent magnet lifter to move synchronously and changing the distance between the permanent magnet lifters on the same side.

[0015] As a preferred embodiment of this utility model, a hinge joint is provided between the connecting rod and the hollow rod to allow the connecting rod to rotate.

[0016] By adopting the above technical solution, the hinge joint ensures the smooth rotation of the connecting rod and the hollow rod.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] The printing press wall panel lifting suction cup adjusts the components according to the length of the cuboid wall panel, causing the rectangular moving rod to move inside the hollow rod. This causes the permanent magnet lifters to move outward synchronously, ensuring that the distance between the two permanent magnet lifters equals the distance between the cuboid wall panels. After adjustment, the angle between the two adjusting rods and the central positioning seat is changed by rotating the adjusting connecting rod on the hinge seat of the central positioning seat, based on the width of the cuboid wall panel. This ensures that the width of the permanent magnet lifters on both sides is equal to the width of the cuboid wall panel, facilitating the attachment and fixation of the four permanent magnet lifters to the four corners of the cuboid wall panel surface, ensuring that the edges are aligned. This guarantees that the central positioning seat is centered on the cuboid wall panel, ensuring overall stability and preventing deviation during lifting when the central positioning seat is connected.

[0023] 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.

[0024] Please see Figures 1 to 3The printing press wall panel hoisting suction cup in this embodiment is mainly composed of a central positioning seat 1, a hinge seat 2, a connecting rod 3, a hollow rod 4, a rectangular moving rod 5, a permanent magnet lifter 6, an adjustment component, and a lifting ring 13. The overall structure achieves the central positioning and hoisting of the cuboid wall panel through the coordinated cooperation of each component, ensuring that the center of gravity remains stable during the hoisting process and avoiding any deviation or tilting.

[0025] The central positioning seat 1, as the core support component of the entire lifting suction cup, is located at the top center of the device. A lifting ring 13 is welded to the center of its upper end. The lifting ring 13 is made of high-strength metal material, such as alloy steel, and has sufficient load-bearing capacity. It is convenient to connect to the lifting rope lock of the lifting equipment to achieve connection with the lifting equipment.

[0026] There are four hinge seats 2, which are respectively set at the four corners of the bottom of the center positioning seat 1. The hinge seats 2 are fixed to the center positioning seat 1 by welding or bolt connection, providing hinge points for the connecting rod 3 and ensuring that the connecting rod 3 can rotate around it.

[0027] There are four connecting rods 3, which are respectively hinged to four hinge seats 2. The connecting rods 3 are made of high-strength metal rods, such as stainless steel rods, which have a certain strength and rigidity. The connecting rods 3 can rotate left and right on both the hinge seats 2 and the hollow rods 4. A hinge joint is provided between the connecting rods 3 and the hollow rods 4. The hinge joint is fixedly connected to the hollow rods 4 and rotates with the connecting rods 3. The hinge joint is made of high-quality alloy material and the surface is smoothed to ensure the smooth rotation of the connecting rods 3 and the hollow rods 4 and reduce the friction during the rotation process.

[0028] There are two hollow rods 4, which are hinged between the left and right connecting rods 3 respectively. The hollow rods 4 are rectangular hollow structures made of aluminum alloy, which are lightweight and high-strength. The hollow rods 4 have rectangular sliding grooves inside at both ends to provide space for the sliding of the rectangular moving rods 5. The sliding grooves are the same length and width as the rectangular moving rods 5.

[0029] There are four rectangular moving rods 5, which are slidably installed in the sliding grooves at both ends of the two hollow rods 4. The rectangular moving rods 5 are made of aluminum alloy material of the same material as the hollow rods 4, and their cross-sectional shape matches the sliding grooves inside the hollow rods 4 to ensure that the rectangular moving rods 5 can slide smoothly inside the hollow rods 4. A permanent magnet lifter 6 is vertically installed at the lower end of the other end of the rectangular moving rods 5. The permanent magnet lifter 6 is fixed to the rectangular moving rods 5 by bolt connection. The permanent magnet lifter 6 is made of high-performance permanent magnet material and has a strong adsorption force, which can firmly adhere to the surface of the cuboid wall panel.

[0030] An adjustment assembly is mounted on the hollow rod 4 to adjust the movement of the rectangular moving rod 5. The adjustment assembly includes mounting seats 7 on the front and rear end surfaces of the hollow rod 4. The mounting seats 7 are fixed to the hollow rod 4 by welding. A rotating shaft seat 8 is fixed to the surface of the front mounting seat 7. The rotating shaft seat 8 is made of high-precision bearings to ensure that the bidirectional threaded rod 9 can rotate smoothly on it. The bidirectional threaded rod 9, which rotates concentrically on the rotating shaft seat 8 and passes through the rear mounting seat 7, is made of high-strength alloy steel and has sufficient strength and wear resistance. The bidirectional threaded rod 9 is based on central symmetry on both sides. The rod has a forward-rotating threaded groove and a reverse-rotating threaded groove. Both the forward-rotating threaded groove and the reverse-rotating threaded groove are threaded with threaded seats 10. The threaded seats 10 are located outside the bidirectional threaded rod 9. Each of the two threaded seats 10 is connected to the permanent magnet lifters 6 on both sides by a connecting rod 12. The connecting rod 12 is made of metal and is connected to the threaded seats 10 and the permanent magnet lifters 6 by welding or bolting. The other end of the bidirectional threaded rod 9 is fixed with a hand-held rotating head 11. The hand-held rotating head 11 is made of plastic or rubber material and has anti-slip texture on the surface to facilitate the operator to rotate the bidirectional threaded rod 9.

[0031] Structural design principles and usage steps

[0032] Length adjustment: Based on the length of the cuboid wall panel, the operator rotates the hand-held rotating head 11, causing the bidirectional threaded rod 9 to rotate on the rotating shaft seat 8 on the mounting base 7. Since the forward and reverse threaded grooves on the bidirectional threaded rod 9 are threadedly connected to the threaded seat 10 respectively, and the hollow rod 4 plays a linear limiting role for the rectangular moving rod 5, when the bidirectional threaded rod 9 rotates, the threaded seat 10 will move in the opposite direction along the bidirectional threaded rod 9, thereby driving the connecting rod 12 and the rectangular moving rod 5 to move, and thus causing the permanent magnet lifter 6 to move outward or inward synchronously, changing the distance between the two permanent magnet lifters 6 on the same side to be equal to the length of the cuboid wall panel.

[0033] Width adjustment: After length adjustment is completed, according to the width of the cuboid wall panel, the operator rotates the adjusting rod 3 on the hinge seat 2 on the center positioning seat 1 to change the angle between the two adjusting rods 3 and the center positioning seat 1. As the angle of the rod 3 changes, the width of the permanent magnet lifters 6 on both sides will also change accordingly to make it equal to the width of the cuboid wall panel.

[0034] Adsorption and fixing: The four permanent magnet lifters 6, with their length and width adjusted, are adsorbed and fixed on the four corners of the surface of the cuboid wall panel, ensuring that the edges are aligned. At this time, the center positioning seat 1 is located in the center of the cuboid wall panel.

[0035] Lifting operation: The lifting equipment is connected to the lifting ring 13 on the center positioning seat 1 by the lifting rope of the lifting equipment. The lifting equipment is started to lift the rectangular wall panel to the designated position for processing. Since the center positioning seat 1 is located in the center of the wall panel, the overall lifting center of gravity can be kept in the center and stable during the lifting process, avoiding the phenomenon of lifting deviation.

[0036] In addition to the main materials of the components mentioned above, in actual production, in order to further improve the performance and service life of the device, the materials of some structures can be optimized. For example, wear-resistant coatings can be used for surface treatment at the connection parts of components such as hinge seat 2, connecting rod 3, and hollow rod 4 to reduce wear between components and extend service life. For permanent magnet lifter 6, permanent magnet materials with better magnetic properties can be selected to improve its adsorption force and stability.

[0037] In summary, the printing press wall panel lifting suction cup of this utility model, through its reasonable structural design and detailed implementation method, can effectively solve the problem of center of gravity shift and tilting that easily occurs when lifting rectangular wall panels in the prior art, and has high practical value and promotion significance.

[0038] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
