Description

Technical Field

[0001] This utility model belongs to the field of cardboard box processing technology, and in particular relates to a surface cleaning device for cardboard box printing. Background Technology

[0002] In the cardboard printing production process, the surface of the cardboard is often covered with impurities such as dust and paper scraps. In order to avoid the impurities affecting the printing quality, the cardboard needs to be cleaned before printing. However, the existing cleaning devices still have some problems.

[0003] For example, the utility model patent with publication number CN220700684U includes: a transport frame, one end of which is provided with an active roller, a driven roller is provided on one side of the active roller, a conveyor belt is provided outside the active roller and the driven roller, and a corrugated cardboard box is provided at the upper end of the conveyor belt.

[0004] This invention uses an air pump to blow clean the surface of cardboard. The cleaning method is relatively simple and has limited effectiveness in cleaning firmly attached particles or electrostatically adsorbed debris. Furthermore, the dust blown out may cause secondary pollution. Utility Model Content

[0005] The purpose of this invention is to provide a surface cleaning device for cardboard printing. By setting up cleaning components, specifically by starting a fan, airflow enters the air knife through an air pipe, and the air knife blows out a high-speed airflow downwards to initially blow away floating dust and loose debris from the cardboard surface. Then, as the cardboard continues to move forward, a drive mechanism drives two cleaning rollers to rotate and brush the cardboard surface, brushing off more firmly attached stains. When the cardboard continues to move under a vacuum cleaner, the suction port at the bottom of the vacuum cleaner sucks in and collects the brushed dust and impurities, thus solving the problem of limited cleaning effect of existing cleaning devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0036] Please see Figures 1-5 As shown, this utility model has the following two specific embodiments.

[0037] Example 1

[0038] This utility model relates to a surface cleaning device for cardboard printing, comprising a conveying component 1 and a cleaning component 2. The conveying component 1 is used to convey cardboard to the area below the cleaning component 2. The conveying component 1 includes a support frame 11. The cleaning component 2 is mounted on top of the support frame 11 and is used for cardboard cleaning. The cleaning component 2 includes:

[0039] Support frame 21 is fixedly connected to the top left side of support frame 11, and air knife 211 is fixedly connected inside support frame 21.

[0040] Air tube 212 is fixedly connected to the front of air knife 211. A fan 213 is fixedly connected to the front of the support frame 11. The air outlet on the back of the fan 213 is fixedly connected to the front of the air tube 212.

[0041] Two support frames 22 are fixedly connected to the top center of the support frame 11, and a cleaning roller 221 is rotatably connected inside the support frame 22.

[0042] The drive mechanism is used to drive the two cleaning rollers 221 to rotate synchronously;

[0043] Vacuum cleaner 23 is fixedly connected to the top right side of the support frame 11, and a suction port 231 is fixedly connected to the bottom of vacuum cleaner 23.

[0044] The drive mechanism includes:

[0045] Two synchronous pulleys 222 are rotatably connected to the front of two support frames 22 respectively, and the back of the synchronous pulleys 222 is fixedly connected to the front of the cleaning roller 221. The two synchronous pulleys 222 are connected by synchronous belt drive.

[0046] Motor 223 is fixedly connected to the back of support frame 22 on the left side via a support frame. The front output end of motor 223 is fixedly connected to the back of cleaning roller 221 on the left side.

[0047] like Figures 1-4 As shown, by setting up the cleaning component 2, specifically by starting the fan 213, the airflow enters the air knife 211 through the air pipe 212. The air knife 211 blows out a high-speed airflow downwards, initially blowing away the floating dust and loose debris on the surface of the cardboard. Then, the cardboard continues to move forward, and the two cleaning rollers 221 are driven by the drive mechanism to rotate, brushing the surface of the cardboard and brushing off the more firmly attached stains. When the cardboard continues to move under the vacuum cleaner 23, the suction port 231 at the bottom of the vacuum cleaner 23 will suck in and collect the brushed dust and impurities, completing the entire cleaning process and improving the cleaning effect.

[0048] The outer surface of the cleaning roller 221 is provided with a soft brush.

[0049] The soft bristles of the cleaning roller 221 prevent scratching the cardboard surface, making it suitable for cartons made of various sensitive materials and improving cleaning safety.

[0050] Example 2

[0051] The difference from Embodiment 1 is that this embodiment discloses how the conveying assembly 1 specifically conveys the cardboard:

[0052] Conveying assembly 1 also includes:

[0053] Several conveying rollers 111 are rotatably connected inside the support frame 11;

[0054] Several gears 112 are rotatably connected to the back of the support frame 11. The front of the gears 112 is fixedly connected to the back of the conveyor roller 111. A gear 2 113 is rotatably connected to the back of the support frame 11 near the two gears 112. The outer surface of the gear 2 113 meshes with the outer surface of the gears 112.

[0055] Motor 114 is fixedly connected to the front of support frame 11 via a support bracket, and the output end of the back of motor 114 is fixedly connected to the front of conveyor roller 111 located on the left side.

[0056] The gear transmission system ensures that the conveyor rollers 111 rotate synchronously, achieving smooth paperboard conveying. The motor 114 provides stable power, improving conveying efficiency and the continuity of the cleaning process.

[0057] Several limiting plates 12 are provided on the top front and back of the support frame 11.

[0058] A support block 121 is fixedly connected to the top of the support frame 11 near the limiting plate 12. A threaded rod 122 is rotatably connected to the top of the limiting plate 12. The outer surface of the threaded rod 122 is threadedly connected to the top of the support block 121. A knob 123 is fixedly connected to the top of the threaded rod 122.

[0059] like Figure 5 As shown, by setting a limiting plate 12, specifically the limiting plate 12 restricts the cardboard to prevent the cardboard from accidentally flying out during the cleaning process. By rotating the knob 123, the threaded rod 122 is driven to rotate in the support block 121, thereby driving the limiting plate 12 to move to a suitable position to adapt to cardboard of different thicknesses and improve the adaptability of the device.

[0060] A specific application of this embodiment is as follows: First, the cardboard box to be cleaned is placed on several conveyor rollers 111. The position of the limiting plate 12 is adjusted according to the thickness of the cardboard. By rotating the knob 123, the threaded rod 122 is driven to rotate in the support block 121, thereby driving the limiting plate 12 to move to a suitable position to restrict the cardboard and prevent the cardboard from accidentally flying out during the cleaning process. The motor 114 is started, and the motor 114 drives the connected conveyor roller 111 to rotate. The gear 112 on the back of the conveyor roller 111 rotates accordingly, and transmits power to other gears 112 through meshing with the gear 2 113, thereby driving all the conveyor rollers 111 to rotate synchronously and smoothly conveying the cardboard to the right. When the cardboard enters the cleaning assembly... In Zone 2, the blower 213 is activated, and the airflow enters the air knife 211 through the air pipe 212. The air knife 211 blows out a high-speed airflow downwards, initially blowing away the floating dust and loose debris on the surface of the cardboard. Then, the cardboard continues to move forward, and the motor 223 is activated. The motor 223 drives the cleaning roller 221 located on the left to rotate. Through the synchronous pulley 222 and the synchronous belt, the cleaning roller 221 on the right rotates synchronously. The cleaning roller 221 then brushes the cardboard, brushing up the more firmly attached stains. When the cardboard continues to move under the vacuum cleaner 23, the suction port 231 at the bottom of the vacuum cleaner 23 sucks in and collects the brushed dust and impurities, completing the entire cleaning process. The soft-bristled cleaning roller 221 avoids scratching the surface of the cardboard box.
