Description
Technical Field
[0001] This utility model relates to the field of cardboard box printing technology, specifically a cardboard box printing pattern registration device. Background Technology
[0002] Currently, most cardboard box printing uses rotary overprinting, which requires precise alignment between the center of the cardboard box and the center of the printing template to ensure accurate pattern registration. With the diversification of e-commerce packaging and the increasing complexity of cardboard box sizes, the cardboard box limiting structure needs to be frequently adjusted during printing to accommodate different sizes.
[0003] However, existing carton printing registration devices lack a synchronous adjustment structure. The limiting components are mostly manually adjusted on one side, making it difficult to ensure the synchronization of bidirectional adjustment. This leads to misalignment between the center of the carton and the center of the printing template, resulting in poor registration. At the same time, the limiting components lack a buffer design, making it easy for the carton to get stuck between the limiting contact plates. Furthermore, the limiting force is uneven, making it difficult to push the carton to move in a centered and parallel manner. In addition, the buffer force adjustment structure is unreasonable, and the parallelism between the contact plate and the rotating column is easily damaged during adjustment, which in turn affects the registration effect. Therefore, there is an urgent need for a carton printing pattern registration device to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a cardboard box printing pattern registration device to solve the problems mentioned in the background art, such as the lack of synchronous adjustment structure, the lack of buffer design of the limiting component, and the difficulty in adjusting the buffer force.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cardboard box printing pattern registration device, comprising a printing press body, wherein both sides of the printing press body are provided with clearance grooves, and further comprising: A synchronous adjustment component is disposed on the bottom surface of the printing press body and is used for bidirectional synchronous adjustment of the limiting components of the carton. A buffer limiting component is disposed on the surface of the printing press body and is used to buffer and limit the carton. A buffer adjustment component is disposed between the synchronization adjustment component and the buffer limit component, and is used to adjust the buffering force of the buffer limit component.
[0006] Preferably, the synchronous adjustment component includes a rotating column, which is rotatably connected to the bottom surface of the printing press body. A spur gear is fixedly connected to the surface of the rotating column. A limit frame is slidably connected to the inner wall of the clearance groove. Two racks are provided on the surface of the spur gear. A fixing groove is opened on the surface of the limit frame. The racks are fixedly connected to the inner wall of the fixing groove. Both racks are meshed with the surface of the spur gear.
[0007] Preferably, the buffer limiting assembly includes two contact plates, both of which are disposed on the side wall of the limiting frame. The side wall of the limiting frame has two movable holes, and a sliding column is slidably connected to the surface of the movable hole. A compression spring is sleeved on the surface of the sliding column.
[0008] Preferably, the buffer adjustment assembly includes multiple adjustment shims, all of which are disposed on the side wall of the limiting frame. One end of the sliding column is provided with a threaded groove, and the inner wall of the threaded groove is threaded with a threaded post. The side wall of the threaded post abuts against one end of the threaded post, and one end of the threaded post is provided with a hexagonal groove. The side wall of the limiting frame is fixedly connected with the hexagonal groove.
[0009] Preferably, a fixed frame is rotatably connected to the surface of the rotating column, the top surface of the fixed frame is fixedly connected to the bottom surface of the printing machine body, a limit wheel is fixedly connected to the surface of the rotating column, a positioning column is slidably connected to the inner wall of the rotating column, a limit tooth block is fixedly connected to the upper end of the positioning column, and a return spring is sleeved on the surface of the positioning column.
[0010] Preferably, the side wall of the limiting frame has a limiting hole, and a square column is slidably connected to the inner wall of the limiting hole. The square column is fixedly connected to the inner wall of the clearance groove.
[0011] Compared with the prior art, the beneficial effects of this utility model are: The synchronous adjustment component facilitates bidirectional synchronous adjustment of the carton's limiting components, ensuring that the center position of the carton always coincides with the center position of the printing template. This facilitates accurate positioning of the carton and the printing template, improving the registration effect between the carton and the printed pattern. Simultaneously, the buffer limiting component cushions the carton during positioning, preventing it from getting stuck between the two contact plates. As the carton moves, the interaction of multiple compression springs pushes both sides of the carton with uniform force, ensuring it moves forward parallel and centered. Furthermore, the buffer adjustment component allows for adjustment of the buffering force of the buffer limiting component. The use of adjustable shims of the same size and flexible addition prevents the parallelism between the contact plates and the rotating column from being affected when adjusting the buffering force.

[0014] 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.
[0015] Please see Figure 1 - Figure 3 The present invention provides a cardboard box printing pattern registration device, including a printing machine body 1, with clearance grooves 2 on both sides of the printing machine body 1, and further including: A synchronous adjustment component is located on the bottom surface of the printing press body 1 and is used for bidirectional synchronous adjustment of the carton's limiting components. A buffer limiting component is disposed on the surface of the printing press body 1 and is used to buffer and limit the carton. A buffer adjustment component is located between the synchronization adjustment component and the buffer limit component, and is used to adjust the buffering force of the buffer limit component. The synchronous adjustment component facilitates bidirectional synchronous adjustment of the carton's limiting components, ensuring that the center position of the carton always coincides with the center position of the printing template. This facilitates center positioning of the carton and the printing template, thereby improving the registration effect between the carton and the printed pattern. Simultaneously, the buffer limiting component provides cushioning during carton positioning, preventing the carton from getting stuck between the two limiting components. As the carton moves, the interaction of multiple buffer components pushes both sides of the carton with uniform force, allowing the carton to move forward in a centered and parallel manner. Furthermore, the buffer adjustment component allows for easy adjustment of the buffering force of the buffer limiting component.
[0016] Furthermore, the synchronous adjustment assembly includes a rotating column 301, which is rotatably connected to the bottom surface of the printing press body 1. A spur gear 302 is fixedly connected to the surface of the rotating column 301. A limit frame 303 is slidably connected to the inner wall of the clearance groove 2. Two racks 305 are provided on the surface of the spur gear 302. A fixing groove 304 is provided on the surface of the limit frame 303. The racks 305 are fixedly connected to the inner wall of the fixing groove 304. Both racks 305 are meshed with the surface of the spur gear 302. A fixed frame 308 is rotatably connected to the surface of the rotating column 301. The top surface of the fixed frame 308 is fixedly connected to the bottom surface of the printing machine body 1. A limit wheel 309 is fixedly connected to the surface of the rotating column 301. A positioning column 310 is slidably connected to the inner wall of the rotating column 301. A limit tooth block 311 is fixedly connected to the upper end of the positioning column 310. A return spring 312 is sleeved on the surface of the positioning column 310. A limit hole 306 is opened on the side wall of the limit frame 303. A square column 307 is slidably connected to the inner wall of the limit hole 306. The square column 307 is fixedly connected to the inner wall of the clearance groove 2. Through the set synchronous adjustment component, the rotation of the rotating column 301 is driven by the interaction of the spur gear 302 and the two racks 305 to drive the two limit frames 303 to move synchronously in opposite directions. This ensures that when the limit components are adjusted according to different sizes of cartons, the center position of the cartons will not change with the change of the limit components. This makes it easy for the center position of the cartons to always coincide with the center position of the printing template, thus facilitating the positioning of the center of the cartons and the printing template, thereby improving the registration effect between the cartons and the printed patterns. The set limit wheel 309 and the limit tooth block 311 work together to limit the limit wheel 309, thus limiting the rotating column 301 and preventing the rotating column 301 from rotating in the normal state. The set square column 307 and the limit hole 306 work together to limit the limit frame 303, thus facilitating the parallel movement of the limit frame 303.
[0017] Furthermore, the buffer limiting assembly includes two contact plates 401, both of which are disposed on the side wall of the limiting frame 303. The side wall of the limiting frame 303 has two movable holes 402, and a sliding post 403 is slidably connected to the surface of each movable hole 402. A compression spring 404 is sleeved on the surface of each sliding post 403. Through the buffer limiting assembly, the movable holes 402 and the sliding post 403 cooperate to limit the contact plates 401, keeping the compression spring 404 parallel to the limiting frame 303. This ensures that when the side wall of the contact plate 401 contacts the carton, the contact plate 401... The side wall of 01 is squeezed by the cardboard box, causing the compression spring 404 to contract and buffer, thus preventing the cardboard box from getting stuck between the two contact plates 401. At the same time, as the cardboard box moves, the interaction of multiple compression springs 404 pushes the two sides of the cardboard box with uniform force, thereby making the cardboard box move forward in a parallel and centered manner. The fixed groove 304 makes it easy to limit the rack 305 and prevent the rack 305 from shifting to the left or right. The rack 305 and the spur gear 302 work together so that the rotation of the spur gear 302 can drive the two limit frames 303 to move synchronously in opposite directions.
[0018] Furthermore, the buffer adjustment assembly includes multiple adjusting shims 501, all of which are disposed on the side wall of the limiting frame 303. One end of the sliding column 403 has a threaded groove 502, and the inner wall of the threaded groove 502 is threadedly connected to a threaded column 503. The side wall of the threaded column 503 abuts against one end of the threaded column 503. One end of the threaded column 503 has a hexagonal groove 504, which is fixedly connected to the side wall of the limiting frame 303. Through the configured buffer adjustment assembly, the thicknesses of the multiple adjusting shims 501 are matched, and the hexagonal groove 504 is threadedly connected to the inner wall of the threaded groove 502, facilitating the removal of the hexagonal groove 504 from the inner wall of the threaded groove 502. The adjusting shims 501 are then fitted onto the surface of the sliding column 403, thereby changing the distance between the threaded column 503 and the limiting frame 303. The larger the distance between the hexagonal groove 504 and the limiting frame 303, the more... The smaller the distance between the limiting frame 303 and the contact plate 401, the easier it is to compress the compression spring 404 between the limiting frame 303 and the contact plate 401, thereby changing the buffering force of the buffer limiting assembly and improving the overall practicality. By adding the same number of adjusting shims 501 to the surfaces of the two sliding columns 403, the distance occupied between the hexagonal groove 504 and the limiting frame 303 is the same, that is, the compression force on the two compression springs 404 is the same, thereby avoiding the impact on the parallelism between the contact plate 401 and the rotating column 301 when adjusting the buffering force of the buffer limiting assembly. Secondly, the multiple adjusting shims 501 make it easy to increase the number of overlaps on the surfaces of the sliding columns 403 as needed, thereby making it easy to adjust the corresponding compression force on the compression spring 404 as needed. The hexagonal groove 504 makes it easy to hang excess spare adjusting shims 501.
[0019] Working Principle: During use, the carton is conveyed forward by the conveyor rollers on the surface of the printing press body 1. Through the synchronous adjustment component, the rotating column 301 rotates, and the spur gear 302 and two racks 305 work together to drive the two limit frames 303 to move synchronously in opposite directions. This ensures that when the limit components are adjusted according to different sizes of cartons, the center position of the carton will not change with the change of the limit components, so that the center position of the carton and the center position of the printing template are always aligned. This facilitates the positioning of the center of the carton and the printing template, thereby improving the registration effect between the carton and the printed pattern. The limit wheel 309 and the limit tooth block 311 work together to limit the limit wheel 309, thereby limiting the rotating column 301 and preventing it from rotating in the normal state. The square column 307 and the limit hole 306 work together to limit the limit frame 303, thereby facilitating the parallel movement of the limit frame 303.
[0020] Meanwhile, the buffer limiting component, through the interaction of the movable hole 402 and the sliding column 403, limits the contact plate 401, keeping the compression spring 404 parallel to the limiting frame 303. When the side wall of the contact plate 401 contacts the carton, the side wall of the contact plate 401 is squeezed by the carton, causing the compression spring 404 to contract and buffer, thus preventing the carton from getting stuck between the two contact plates 401. At the same time, as the carton moves, the interaction of multiple compression springs 404 pushes the two sides of the carton with uniform force, thereby making the carton move forward in a parallel and centered manner. The fixed groove 304 facilitates the limiting of the rack 305, preventing the rack 305 from shifting left or right. The rack 305 and the spur gear 302 work together, so that the rotation of the spur gear 302 drives the two limiting frames 303 to move synchronously in opposite directions.
[0021] Secondly, through the configured buffer adjustment assembly, multiple adjusting shims 501 are matched in thickness, and the hexagonal groove 504 is threadedly connected to the inner wall of the threaded groove 502, making it easy to remove the hexagonal groove 504 from the inner wall of the threaded groove 502. The adjusting shims 501 are then fitted onto the surface of the sliding column 403, thereby changing the distance between the threaded column 503 and the limiting frame 303. The larger the distance between the hexagonal groove 504 and the limiting frame 303 through the adjusted shims 501, the smaller the distance between the limiting frame 303 and the contact plate 401, thus facilitating the compression of the spring 404 between the limiting frame 303 and the contact plate 401, thereby changing the distance between them. The variable buffer limit component improves overall practicality by adding the same number of adjusting shims 501 to the surfaces of the two sliding columns 403. This ensures that the distance between the hexagonal groove 504 and the limit frame 303 is the same, meaning that the compression force on the two compression springs 404 is the same. This prevents the parallelism between the contact plate 401 and the rotating column 301 from being affected when adjusting the buffer limit component. Furthermore, the multiple adjusting shims 501 allow for easy adjustment of the overlap on the surfaces of the sliding columns 403 as needed, thus facilitating the adjustment of the compression force on the compression springs 404 accordingly.
