Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a metal roll plate printing device that is easy to replace. Background Technology

[0002] Metal roll sheets are typically made of thin metal materials, such as galvanized steel, tinplate, or aluminum. Metal roll sheet printing is primarily used to apply patterns, markings, or protective coatings to metal surfaces. These coatings enhance the metal surface's corrosion resistance, abrasion resistance, and weather resistance. The printing rollers are one of the core components of metal roll sheet printing equipment, transferring ink to the metal roll sheet surface. Under the roller drive of modern printing equipment, the metal roll sheet is printed, and then temporarily stored after printing for subsequent transportation and processing.

[0003] However, in common metal roll-to-roll printing equipment, multiple roller groups need to be disassembled together with the transmission structure during disassembly, which increases the difficulty of disassembly and subsequent installation, reduces operating efficiency, and also affects subsequent printing operations. In view of this, we propose a metal roll-to-roll printing equipment that is easy to replace. Utility Model Content

[0004] The purpose of this invention is to provide a metal roll plate printing device that is easy to replace, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a frame, within which are arranged a motor, motor base, ink fountain, hot air blower, storage roller, preheating roller, auxiliary roller, printing roller, and roll-up roller. Positioning components are symmetrically installed on the side walls of the storage roller, preheating roller, auxiliary roller, printing roller, and roll-up roller. A motor base and ink fountain are installed on the front wall of the frame, and a motor is installed on the top wall of the motor base. Rotating components are provided at each of the positioning components. Each rotating component includes a rotating seat with an N-shaped groove. An operating cavity is formed within the protruding structure inside the N-shaped groove. A positioning component is installed within the operating cavity. Each positioning component includes a moving block with a trapezoidal structure. Sockets are symmetrically arranged on the inclined surfaces of both sides of the moving block. Springs are connected to the back walls of both sockets. A threaded hole is formed within the moving block, and a screw passes through the threaded hole.

[0006] Preferably, an auxiliary plate is installed on the top wall of the frame, and a nozzle is connected to the bottom wall of the auxiliary plate, with the air outlet of the hot air blower communicating with the inside of the nozzle.

[0007] By adopting the above technical solution, the printed area can be dried by blowing air through a hot air blower in conjunction with the nozzle connected to it.

[0008] Preferably, a sealing plate is arranged at the top opening of the ink fountain, and hinges are symmetrically arranged on the sealing plate and the side wall of the ink fountain. The bottom opening of the ink fountain is arc-shaped, and the printing roller is adapted to the bottom opening of the ink fountain.

[0009] By adopting the above technical solution, ink can be applied to the printing roller through the feeding action of the ink fountain, so that the metal roll plate passing through the printing roller can complete the printing process.

[0010] Preferably, the positioning member is N-shaped and is inserted into the N-shaped groove corresponding to the position. Positioning holes are symmetrically opened on the vertical structural walls on both sides of the positioning member, and sliding holes are symmetrically opened on the two side walls of the rotating seat protruding structure. The sliding holes correspond to the positions of the positioning holes.

[0011] By adopting the above technical solution, the N-shaped setting of the positioning component can be used in conjunction with the N-shaped groove to perform preliminary installation and positioning of the roller group corresponding to the position. Furthermore, with the corresponding setting of the sliding hole and the positioning hole, it is beneficial to fix the positioning component installed on the rotating groove in the subsequent process.

[0012] Preferably, rotating holes are symmetrically opened on both sides of the frame, a rotating shaft is connected to the back wall of the rotating seat, the rotating shaft passes through the rotating hole corresponding to the position, a bearing is sleeved on the outer surface wall of multiple rotating shafts, and the end of one rotating shaft is connected to the output end of the motor.

[0013] By adopting the above technical solution, the shaft after passing through the rotating hole can rotate with the assistance of the bearing, which is beneficial for the subsequent conveying of the metal roll plate and provides convenience for printing operations.

[0014] Preferably, a limiting rotating ring is welded to the back wall of the rotating seat, and limiting rotating grooves are symmetrically opened on the inner walls of both sides of the frame, with multiple limiting rotating rings respectively embedded in the corresponding limiting rotating grooves;

[0015] By adopting the above technical solution, the stability of the rotating seat during subsequent rotation can be improved through the combined action of the limiting rotating groove and the limiting rotating ring.

[0016] Preferably, guide sliders are symmetrically installed on both sides of the movable block, and the back walls of the two sockets are both protruding, with limit sliders connected to the back walls of the two sockets.

[0017] By adopting the above technical solution, with the assistance of the guide slider and the limit slider, it is beneficial to guide the moving block and the socket, which facilitates the subsequent positioning and release of the two.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] This invention uses a motor to drive a rotating shaft at a corresponding position, causing the rotating seat to rotate. Under the feeding action of the ink fountain, the printing roller is driven by the transmission wheel and transmission belt to rewind and print the metal roll plate that has passed through the ink fountain. The hot air blower and nozzle are used to dry the printed metal roll plate. At the same time, the screw's turning action drives the moving block to descend, causing the elasticity of the two springs to release and push the socket to move, releasing the positioning component. This makes it convenient for workers to disassemble and replace the storage roller, preheating roller, auxiliary roller, printing roller, and roll roller, preventing the influence of the drive and transmission structure and reducing the difficulty of disassembly and assembly.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figures 1 to 4As shown, this utility model proposes a metal roll plate printing equipment with easy replacement, including a frame 1, an ink fountain 17, a hot air blower 11, a storage roller 2, a preheating roller 3, an auxiliary roller 4, a printing roller 5, a controller 18, and a roll roller 6. Multiple positioning components 7 are grouped in pairs, with two N-shaped positioning components 7 in each group symmetrically installed on the side walls of the storage roller 2, preheating roller 3, auxiliary roller 4, printing roller 5, and roll roller 6 for easy installation and positioning. Multiple sets of rotating components 8 are also grouped in pairs, with two rotating components 8 in each group symmetrically installed on the inner wall of the frame 1. Each rotating component 8 includes a rotating base 81 and a rotating shaft. The rotating seat 81 has an N-shaped groove on its side wall, and the positioning member 7 is inserted into the corresponding N-shaped groove, which is supported by the rotating seat 81. One end of the rotating shaft 82 is fixedly connected to the back wall of the rotating seat 81, and also passes through multiple rotating holes on both sides of the frame 1. Each rotating hole contains a bearing, which is sleeved on the outer surface of the rotating shaft 82 to assist the rotating shaft 82 in driving the rotating seat 81 to rotate, which is beneficial for subsequent printing on the metal roll plate. The limiting rotating ring 83 is fixedly installed on the back wall of the rotating seat 81, and is also embedded in the limiting rotating grooves symmetrically opened on both sides of the inner wall of the frame 1 to improve the stability of the rotating seat 81 during rotation.

[0028] Furthermore, the motor 13 is mounted on the motor base 14 for easy support, and the motor base 14 is fixedly mounted on the front-view wall of the frame 1; a set of rotating components 8 includes a rotating shaft 82 whose end is connected to the output end of the motor 13, so that the corresponding roll roller 6 can be rotated under the drive of the motor 13, which facilitates the winding of the printed metal roll plate, and is conducive to its temporary storage, which is convenient for subsequent disassembly and processing of the roll roller 6; two transmission wheels 15 are sleeved on the outer surface wall of the corresponding rotating shaft 82, and the transmission belt 16 is sleeved in the transmission groove of the transmission wheel 15, which plays a transmission role, so that the printing roller 5 can be rotated under the rotation of the roll roller 6, which facilitates printing on the metal roll plate.

[0029] Furthermore, the auxiliary plate 10 is fixedly installed on the top wall of the frame 1. The nozzle is plate-shaped and fixedly installed on the bottom wall of the auxiliary plate 10. The auxiliary plate 10 has a first through hole, and the nozzle has a second through hole. The hot air blower 11 is installed on the top wall of the auxiliary plate 10 and communicates with the inside of the nozzle through the first and second through holes to facilitate the drying of the metal roll plate. This prevents the printed area of ​​the metal roll plate from becoming blurred due to the rewinding effect after it has not been completely dried, thus reducing the quality of the printed product. Part of the top wall of the ink fountain 17 is fixedly connected to the bottom wall of the auxiliary plate 10. The sealing plate 12 is hinged to it in conjunction with the hinges symmetrically installed on the side wall of the ink fountain 17 to facilitate the closure of the top opening of the ink fountain 17. When opened, it is convenient to replenish ink in the ink fountain 17 for subsequent printing. Part of the structure of the printing roller 5 is embedded in the arc-shaped opening at the bottom of the ink fountain 17, which is beneficial for printing the metal roll plate in conjunction with the printing roller 5.

[0030] Furthermore, the positioning component 9 includes a moving block 91, a socket 92, a spring 93, a limiting slider 94, a screw 95, a bearing seat 96, and a guide slider 97. The moving block 91 is disposed in the operating cavity opened within the protruding structure of the rotating seat 81. An auxiliary hole is opened on the bottom wall of the rotating seat 81. The bearing seat 96 is fixedly installed on the top cavity wall of the operating cavity and corresponds to the position of the auxiliary hole. The end of the screw 95 passes through the auxiliary hole and the threaded hole opened on the moving block 91, and is connected to the rotating end of the bearing seat 96. Since the front wall and back wall of the moving block 91 are in close contact with the inner wall of the operating cavity, it is convenient to adjust the height of the moving block 91 under the rotation of the screw 95. Two guide sliders 97 are symmetrically installed on the two side walls of the moving block 91. Slide openings, slide grooves, and grooves are symmetrically opened on the two side walls of the operating cavity. The two guide sliders 97 are respectively inserted into the corresponding slide grooves to guide the moving block 91 in the lifting state and assist the moving block 91 in moving.

[0031] Two sockets 92 are symmetrically arranged. The ends of springs 93 connected to the back walls of the two sockets 92 are also connected to the groove wall to assist the sockets 92 in resetting. Limiting grooves are opened in the cavity wall of the operating chamber. Two limiting sliders 94 connected to the back walls of the sockets 92 are set in the corresponding limiting grooves to guide the sockets 92 in the moving state and assist the stability of the sockets 92 during the movement. The side wall of the sockets 92 near the moving block 91 is set in an inclined state and is adapted to the inclined surface of the trapezoidal moving block 91 to facilitate the subsequent positioning of the positioning component 7 by the sockets 92. The positioning holes are symmetrically opened on the two side walls of the positioning component 7. The position of the positioning holes corresponds to the position of the sliding holes. The protruding structure of the back wall of the sockets 92 can pass through the sliding holes and be inserted into the positioning holes to fix the position of the positioning component 7. Conversely, it is convenient to release the limit.

[0032] In this embodiment, the rotating shaft 82 corresponding to the starting position is driven by the starting motor 13 to rotate the rotating seat 81. This causes the metal roll plate wound on the storage roller 2 and the winding roller 6 to pass through the preheating roller 3, the auxiliary roller 4, and the printing roller 5 under the action of rotation, thus achieving printing processing on the metal roll plate. Simultaneously, the hot air blower 11 is activated to dry the printed metal roll plate to prevent the printed area from being affected by the winding process and reducing the quality of the finished product. When ink needs to be replenished, the sealing plate 12 can be opened. When the storage roller 2, the preheating roller 3, the auxiliary roller 4, the printing roller 5, and the winding roller 6 need to be replaced, the screw 95 can be turned to drive the moving block 9. The descent of spring 92 causes the two sockets 92 to move in the same direction under the elastic release of spring 93. This causes the protruding structure on the side wall of socket 92 to disengage from the positioning hole, releasing the positioning part 7 corresponding to the position. This allows the staff to disassemble and replace the material storage roller 2, preheating roller 3, auxiliary roller 4, printing roller 5, and winding roller 6 individually according to their usage. It also reduces interference from the transmission structure during disassembly and simplifies the operation. Conversely, when installation is required, the positioning part 7 can be inserted into the corresponding N-shaped groove, and turning 85 will cause the moving block 91 to rise, squeezing the two sockets 92 to move in opposite directions and inserting their protruding structures into the positioning groove to complete the positioning.
