Description

Technical Field

[0001] This utility model relates to the field of cardboard box color printing technology, and in particular to a fixed module for cardboard box color printing. Background Technology

[0002] In the corrugated box packaging industry, color printing is a key step in enhancing product added value and market competitiveness. It involves printing patterns, text, trademarks, and other information on the surface of the corrugated box to achieve product identification, promotion, and brand building. To ensure the stability of the corrugated box during the color printing process and avoid problems such as misalignment or blurring of printed patterns due to displacement, a fixing device for color printing has become an indispensable piece of equipment.

[0003] With the increasing market demand for diverse carton sizes, single-size fixing devices can no longer meet production needs, leading to the development of adjustable carton color printing fixing devices. In existing technologies, these adjustable devices typically use screw-driven linkages or similar structures to adjust the fixed size, adapting to the fixing requirements of different carton sizes. Specifically, they usually utilize the rotational motion of the screw to convert it into the linear motion of the linkage, driving the clamping or supporting components to extend, retract, or move, thereby changing the size of the fixing space.

[0004] However, the aforementioned screw-driven linkage structure has significant drawbacks: Firstly, the overall structure involves multiple precision-fitting components such as the screw, nut, linkage, and bearings, resulting in a complex structure that increases manufacturing difficulty and cost, and makes assembly and maintenance more cumbersome. Secondly, the environment in carton printing workshops often contains dust and ink volatiles, making the screw prone to corrosion and jamming after prolonged use, especially in high-humidity environments. When the screw corrodes or jams, operators cannot easily adjust it manually, affecting production efficiency and potentially causing damage such as screw breakage or linkage deformation due to forced rotation, leading to inconvenience and additional maintenance costs. Therefore, existing adjustable carton printing fixing devices still require further improvement in terms of structural simplification and operational reliability. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a fixing module for color printing on cardboard boxes.

[0006] A fixed module for color printing on cardboard boxes designed for this purpose includes a base and a first movable plate and a second movable plate spaced apart front and back. A first clamping plate is provided on the right side of the first movable plate and a second clamping plate is provided on the left side of the second movable plate.

[0007] The first and second movable plates are positioned to move left and right relative to the base.

[0008] The first movable plate and the second movable plate are connected by a transmission module; the transmission module includes a first rack fixedly mounted on the first movable plate, a second rack fixedly mounted on the second movable plate, and a transmission gear that meshes with the first rack and the second rack.

[0009] The transmission gear is rotatably configured relative to the base;

[0010] The base is provided with a locking module for restricting the left and right movement of the first and second movable plates relative to the base.

[0011] Preferably, the locking module includes a locking rod that can move back and forth relative to the base, and the locking rod is provided with locking teeth;

[0012] The transmission gear is connected to a locking gear;

[0013] The locking lever can move relative to the base between a locked position and an unlocked position;

[0014] When the locking lever is in the locked position, the locking tooth is inserted into any one of the slots of the locking gear.

[0015] When the locking lever is in the unlocked position, the locking teeth separate from the grooves of the locking gear.

[0016] Preferably, the locking rod has two pin holes arranged along its moving direction, and the base is provided with a locking pin that can move up and down relative to the base and can be movably inserted into either pin hole.

[0017] Preferably, the base is provided with mounting ears, and the locking pin is movably inserted into the mounting hole of the mounting ears and is movable up and down relative to the mounting ears;

[0018] A connecting element is provided on the locking pin below the mounting ear, and a spring is sleeved on the locking pin between the connecting element and the mounting ear;

[0019] When the spring releases its stored force, it can push the locking pin to move from top to bottom.

[0020] Preferably, the transmission gear is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the base;

[0021] The locking gear is fixedly mounted on the rotating shaft.

[0022] Preferably, the locking rod is provided with a through groove running vertically through it, and both the rotating shaft and the locking gear are disposed within the through groove;

[0023] The locking teeth are disposed on the front or rear side wall of the through groove.

[0024] Preferably, the base is provided with several guide rails extending in the left and right directions, and the lower surfaces of the first and second movable plates are provided with sliders, which are slidably connected to the guide rails.

[0025] Preferably, the first and second movable plates are hollow and have air channels, and the surfaces of the first and second movable plates are provided with air inlets that communicate with the air channels.

[0026] The wall surface of the first movable plate facing the second movable plate and the wall surface of the second movable plate facing the first movable plate are both provided with air outlets that communicate with the air flow channel.

[0027] Compared with the prior art, this utility model has a fixed module for printing on cartons. Through the meshing of the transmission gear with the first rack and the second rack, the first moving plate and the second moving plate can move synchronously in opposite directions. Only the transmission gear needs to be driven to adjust the distance between the first clamping plate and the second clamping plate. This effectively simplifies the complex structure of the traditional adjustable fixing device that relies on the screw to drive the connecting rod, reduces the number of precision-fitting parts, and lowers the production and maintenance costs.

[0028] Meanwhile, the use of rack and pinion transmission instead of screw structure avoids the problems of screw corrosion and jamming in dust, ink volatiles and humid environments, ensuring smooth adjustment operation during long-term use. There is no need to worry about the inability to manually drive due to corrosion, thus improving the reliability and stability of the device operation.

[0029] In addition, the locking module can quickly constrain the positions of the first and second moving plates, ensuring that cartons of different sizes are stably clamped during the color printing process, reducing problems such as printing misalignment and blurring caused by unstable fixing, and further improving the efficiency and quality of carton color printing.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] See Figures 1-6 A fixing module for color printing on cardboard boxes includes a base 10 and a first movable plate 20 and a second movable plate 30 spaced apart front to back. A first clamping plate 210 is provided on the right side of the first movable plate 20, and a second clamping plate 310 is provided on the left side of the second movable plate 30. The first movable plate 20 and the second movable plate 30 are movable left and right relative to the base 10. The first movable plate 20 and the second movable plate 30 are drivenly connected to a transmission module 50. The transmission module 50 includes a first rack 510 fixedly mounted on the first movable plate 20, a second rack 520 fixedly mounted on the second movable plate 30, and a transmission gear 530 meshing with the first rack 510 and the second rack 520. The transmission gear 530 is rotatable relative to the base 10. The base 10 is provided with a locking module 60 for constraining the left and right movement of the first movable plate 20 and the second movable plate 30 relative to the base 10.

[0038] When using this fixed module for color printing on cartons, no additional drive gear is required. Simply pull the first moving plate 20 or the second moving plate 30 directly. When the first moving plate 20 is pulled left or right, the first rack 510 at its bottom will drive the drive gear 530 meshing with it to rotate. The drive gear 530, in turn, will drive the second moving plate 30 to move synchronously in the opposite direction to the first moving plate 20 through meshing with the second rack 520. Similarly, if the second moving plate 30 is pulled left or right, the first moving plate 20 will also move synchronously in the opposite direction under the meshing transmission of the first rack 510, the second rack 520 and the drive gear 530. This allows for flexible adjustment of the distance between the first clamping plate 210 and the second clamping plate 310 to accommodate cartons of different widths. After the spacing is adjusted to the correct position, the first moving plate 20 and the second moving plate 30 are constrained by the locking module 60. The first clamping plate 210 and the second clamping plate 310 can then stably clamp the carton from both sides, ensuring the stability of the carton's position during the color printing process and ensuring printing accuracy.

[0039] In this utility model, handles can be provided on the first movable plate 20 or the second movable plate 30 according to different usage requirements, so that workers can pull the first movable plate 20 or the second movable plate 30.

[0040] See Figures 3 to 6The locking module 60 includes a locking rod 610 that can move back and forth relative to the base 10, and the locking rod 610 is provided with locking teeth 630; the transmission gear 530 is connected to the locking gear 550; the locking rod 610 can move relative to the base 10 between a locked position and an unlocked position.

[0041] like Figure 4 As shown, when the locking lever 610 is in the locked position, the locking tooth 630 is inserted into any one of the tooth slots of the locking gear 550;

[0042] like Figure 6 As shown. When the locking lever 610 is in the unlocked position, the locking tooth 630 separates from the tooth groove of the locking gear 550.

[0043] The working principle of the locking module 60 is based on the cooperation between the locking rod 610 and the locking gear 550 to brake and release the transmission gear 530: the locking gear 550 is connected to the transmission gear 530 and rotates synchronously with the transmission gear 530. When it is necessary to fix the position of the first moving plate 20 and the second moving plate 30, push the locking lever 610 forward relative to the base 10 to the locking position. At this time, the locking teeth 630 on the locking lever 610 are precisely inserted into any one of the tooth slots of the locking gear 550. The meshing between the teeth restricts the rotation of the locking gear 550, thereby preventing the rotation of the transmission gear 530 connected to it, so that the first rack 510 and the second rack 520 cannot move, and the position of the first moving plate 20 and the second moving plate 30 is fixed. When it is necessary to adjust the clamping plate spacing, pull the locking lever 610 backward relative to the base 10 to the unlocking position. The locking teeth 630 separate from the tooth slots of the locking gear 550, releasing the constraint on the locking gear 550 and the transmission gear 530. At this time, the transmission gear 530 can rotate freely, ensuring that the first moving plate 20 and the second moving plate 30 can be flexibly adjusted in position.

[0044] See Figure 4 The locking rod 610 has two pin holes 640 arranged along its moving direction. The base 10 is provided with a locking pin 650 that can move up and down relative to the base 10 and can be movably inserted into either pin hole 640. The locking pin 650 can move up and down and be movably inserted into the two pin holes 640 of the locking rod 610, fixing the locking rod 610 in the locked and unlocked positions respectively, preventing the locking rod 610 from moving accidentally and changing the locked state, and ensuring that the locking and unlocking functions are stable and reliable.

[0045] See Figure 4The base 10 is provided with a mounting ear 110. The locking pin 650 is movably inserted into the mounting hole of the mounting ear 110 and is movable up and down relative to the mounting ear 110. A connecting element 660 is provided on the locking pin 650 below the mounting ear 110. A spring 670 is sleeved on the locking pin 650 between the connecting element 660 and the mounting ear 110. Under the stored force release of the spring 670, the locking pin 650 can move downward along the mounting hole of the mounting ear 110 to limit and fix the locking rod 610, ensuring the stability of the locking module in the locked position. Pulling the locking pin 650 upward to compress the stored force of the spring can release the constraint on the locking rod 610, making it easy to switch to the unlocked position.

[0046] See Figure 4 The transmission gear 530 is fixedly connected to the rotating shaft 540, and the rotating shaft 540 is rotatably connected to the base 10; the locking gear 550 is fixedly mounted on the rotating shaft 540.

[0047] See Figure 4 The locking rod 610 is provided with a through groove 620 that runs vertically through the shaft, and the rotating shaft 540 and the locking gear 550 are both provided in the through groove 620; the locking tooth 630 is provided on the front or rear side wall of the through groove 620.

[0048] See Figure 4 The base 10 is provided with a plurality of guide rails 410 extending in the left and right directions. The lower surfaces of the first moving plate 20 and the second moving plate 30 are provided with sliders 420, which are slidably connected to the guide rails 410.

[0049] See Figure 1 The first movable plate 20 and the second movable plate 30 are hollow inside and have air channels. Air inlets 710 communicating with the air channels are provided on the surfaces of the first movable plate 20 and the second movable plate 30. Air outlets 720 communicating with the air channels are provided on the wall surfaces of the first movable plate 20 facing the second movable plate 30 and the second movable plate 30 facing the first movable plate 20. The hollow interiors of the first and second movable plates form air channels, and the air inlets on their surfaces are connected to an external air supply device via flexible hoses to introduce a stable airflow. After being conducted through the air channels, the airflow is blown out from the air outlets on the opposing walls of the two plates. When the carton is clamped, this not only removes dust and other impurities adhering to the carton surface, preventing impurities from interfering with the color printing effect, but also helps to keep the carton surface dry, reducing printing defects caused by moisture and further ensuring the quality of color printing.
