Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box printing production technology, and in particular to an automatic feeding device for corrugated cardboard box printing. Background Technology

[0002] In the corrugated cardboard box printing industry, traditional feeding methods have long constrained production efficiency and product quality improvement. In the past, it relied heavily on manual handling of cardboard boxes to the printing press inlet. This not only consumed a lot of manpower and caused great labor intensity for workers, but was also inefficient, with a limited feeding capacity per hour. At the same time, manual operation made it difficult to ensure that the cardboard boxes were placed in a precise and consistent position each time, which easily caused printing deviations and a high defect rate. Furthermore, as the market demand for personalized and diversified cardboard box printing has gradually increased, the traditional feeding method requires a long adjustment period when frequently changing cardboard box specifications, which cannot adapt to the fast production pace. Against this background, automatic feeding equipment for corrugated cardboard box printing has emerged to solve these problems.

[0003] A search revealed Chinese Patent Publication No. CN219544162U, which discloses an automatic feeding device for corrugated cardboard box printing, belonging to the field of corrugated cardboard box printing technology. The device includes a base plate, with four first hydraulic rods fixedly connected to the upper center of the base plate. The telescopic ends of the four first hydraulic rods are fixedly connected to the same placement plate. L-shaped support frames are fixedly connected to the front and rear ends of the placement plate. This invention uses a conveyor belt in a first conveying assembly to transport the corrugated paper body to the upper front side of the placement plate, where it slides onto the upper part of the placement plate via an inclined guide plate, avoiding the need for timely replenishment of the corrugated paper body on the placement plate by workers. By activating an electric telescopic rod, the extension of the electric telescopic rod moves a leveling plate, leveling both sides of the corrugated paper body. After leveling, the electric telescopic rod retracts, moving away from the corrugated paper body, making the front and rear ends of the stacked corrugated paper align. This device facilitates automatic feeding of printed corrugated paper and is highly efficient. However, in actual use, for corrugated paper of different sizes, tilting can easily occur during feeding, ultimately leading to non-conforming printed products. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic feeding device for corrugated cardboard box printing, which aims to improve the problem in the prior art where corrugated paper of different sizes is easily tilted during printing when being fed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding device for corrugated cardboard box printing, comprising a printing machine and a concave plate, wherein a conveyor belt is fixedly connected to the inner wall of the printing machine, a movable plate is slidably connected to the inner wall of the concave plate, limiting grooves are provided on the left and right sides of the top of the movable plate, limiting plates are slidably connected to the front and rear sides of the two limiting grooves, rotating disks are slidably connected to the front and rear sides of the inner wall of the concave plate, and support columns are fixedly connected to adjacent sides of the two rotating disks, and multiple sliding strips are fixedly connected to the front and rear sides of the movable plate, and the multiple sliding strips are slidably connected to the inner wall of the concave plate, a servo motor is fixedly connected to the front left side of the outer wall of the concave plate, a pulley one is fixedly connected to the output end of the servo motor, a pulley two is fixedly connected to the front side of the front rotating disk, belts are provided on the outer walls of the pulley one and the pulley two, and a pulling mechanism is provided on the top of the conveyor belt.

[0006] The above technical solution involves placing corrugated paper on top of a moving plate, then pushing the limiting plates on both sides to compress the corrugated paper stack, ensuring it is neatly stacked on top of the moving plate and centered. At this point, a servo motor is activated to rotate pulley one, which in turn rotates pulley two via a belt, causing the rotating disk to rotate. The support column then rotates accordingly, moving the moving plate upwards, thus ensuring the corrugated paper stack is slowly moved upwards.

[0007] As a further description of the above technical solution:

[0008] The pulling mechanism includes a U-shaped support frame, which is fixedly connected to the top right side of the conveyor belt. A sliding plate is provided at the bottom of the U-shaped support frame, and a trapezoidal strip is fixedly connected to the top left side of the sliding plate. The outer wall of the trapezoidal strip is slidably connected to the U-shaped support frame. An electric telescopic rod is fixedly connected to the top of the U-shaped support frame, and one end of the electric telescopic rod is fixedly connected to the sliding plate. An air pump is fixedly connected to the rear left side of the outer wall of the concave plate. One end of the air pump is connected to a hose, and the right side of the outer wall of the hose passes through the sliding plate and is connected to a suction cup.

[0009] The above technical solution works as follows: when the top corrugated paper in the corrugated paper stack comes into contact with the suction cup, the air pump is activated simultaneously. Through the hose and suction cup, a negative pressure is generated in the space where the corrugated paper is in contact, thereby adsorbing the corrugated paper. Then, the electric telescopic rod is activated to drive the sliding plate to retract. Subsequently, under the restriction of the trapezoidal strip, the sliding plate can move on the U-shaped support frame, thereby pulling the adsorbed corrugated paper upwards on the conveyor belt. After the corrugated paper is moved above the conveyor belt, the air pump is activated again to release the negative pressure between the hose and the suction cup, thereby putting down the corrugated paper and completing the corrugated paper loading step.

[0010] As a further description of the above technical solution:

[0011] An observation window is provided on the front side of the outer wall of the printing press, and an outer frame is fixedly connected to the outer wall of the observation window.

[0012] The above technical solution allows for observation of the printing process through a viewing window, and the outer frame enhances the strength of the viewing window.

[0013] As a further description of the above technical solution:

[0014] A nameplate is fixedly connected to the bottom front side of the outer wall of the concave plate, and a warning sign block is fixedly connected to the top front side of the outer wall of the concave plate.

[0015] The above technical solution allows for easy recording of equipment models via nameplates, and warning labels can easily remind operators of precautions during use.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the limiting plate is provided with anti-slip grooves, which are equidistantly formed on the outer wall of the limiting plate.

[0018] The above technical solution improves the anti-slip capability of the limiting plate by using anti-slip grooves, and the equidistant grooves enhance the uniformity of force distribution.

[0019] As a further description of the above technical solution:

[0020] An alarm light is fixedly connected to the top front side of the sliding plate, and an adjustment valve is fixedly connected to the outer wall of the hose.

[0021] The above technical solution allows for the use of an alarm light to alert operators in case of malfunction, and the adjustment valve allows for easy control of the suction force of the suction cup.

[0022] As a further description of the above technical solution:

[0023] The concave plate has sliding grooves on both the front and rear sides of its inner wall, and the sliding grooves are slidably connected to the corresponding sliding strips.

[0024] The above technical solution facilitates the sliding of the slider by using a sliding groove.

[0025] As a further description of the above technical solution:

[0026] A positioning block is slidably connected to the right side of the outer wall of the limiting plate, and multiple positioning holes are opened on the top right side of the outer wall of the moving plate, with the positioning block engaging with the positioning holes.

[0027] The above technical solution allows for the fixed adjustment of the rear limit plate position by engaging the positioning block with the positioning hole.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by placing corrugated paper on a moving plate, pushing the limiting plate to squeeze the paper stack to keep it neat and place it in the center, starting the servo motor, and the rotation of pulley one drives the belt and pulley two to rotate the rotating disk and support column, thereby moving the moving plate upward, thus slowly lifting the corrugated paper stack, so that corrugated paper of different sizes can be neatly placed on the conveying device.

[0030] 2. In this invention, when the corrugated paper comes into contact with the suction cup, an air pump is activated to generate negative pressure to adsorb the corrugated paper. Then, an electric telescopic rod drives the sliding plate to retract, and a trapezoidal strip restricts its movement on the U-shaped frame, pulling the corrugated paper upwards onto the conveyor belt. Finally, the negative pressure is released, and the corrugated paper is lowered, completing the loading process. Attached Figure Description

A conveyor belt 3 is fixedly connected to the inner wall of the printing machine 1, and a movable plate 5 is slidably connected to the inner wall of the concave plate 4. The top left and right sides of the movable plate 5 are provided with limiting grooves 7, and the front and rear sides of the two limiting grooves 7 are slidably connected with limiting plates 6. Corrugated paper is placed above the movable plate 5, and then the limiting plates 6 on both sides are pushed to compress the stack of corrugated paper, thereby ensuring that it is neatly stacked above the movable plate 5 and that the stack of corrugated paper is centered. Rotary disks 10 are slidably connected to the front and rear sides of the inner wall of the concave plate 4, and support columns 11 are fixedly connected to adjacent sides of the two rotating disks 10. The servo motor 13 is started to drive pulley 14 to rotate, which in turn drives pulley 16 to rotate via belt 15, thereby causing the rotating disk 10 to rotate. At this time, the support column 11 will rotate accordingly, thereby driving the moving plate 5 to move to the top. Multiple sliding bars 12 are fixedly connected to the front and rear sides of the moving plate 5. Multiple sliding bars 12 are slidably connected to the inner wall of the concave plate 4. The servo motor 13 is fixedly connected to the front left side of the outer wall of the concave plate 4. The output end of the servo motor 13 is fixedly connected to pulley 14.

Pulling mechanism 2 is provided on the top of the conveyor belt 3.

[0040] Specifically, the corrugated paper is placed on top of the moving plate 5, and then the limiting plates 6 on both sides are pushed to squeeze the corrugated paper stack, thereby ensuring that it is neatly stacked on top of the moving plate 5 and that the corrugated paper stack is in the center. At this time, the servo motor 13 is started to drive the pulley 14 to rotate, which in turn drives the pulley 16 to rotate through the belt 15, thereby causing the rotating disk 10 to rotate. At this time, the support column 11 will rotate accordingly, thereby driving the moving plate 5 to move to the top, thus ensuring that the corrugated paper stack can be slowly moved upward.

One end of the air pump 205 is connected to a hose 206. The right side of the outer wall of the hose 206 passes through the sliding plate 202 and is connected to a suction cup 207. When the air pump 205 is started, a negative pressure is generated in the space in contact with the corrugated paper through the hose 206 and the suction cup 207, thereby adsorbing the corrugated paper.

[0042] Specifically, when the top corrugated paper in the corrugated paper stack comes into contact with the suction cup 207, the air pump 205 is activated. Through the hose 206 and the suction cup 207, a negative pressure is generated in the space where the corrugated paper is in contact, thereby adsorbing the corrugated paper. Then, the electric telescopic rod 204 is activated to drive the sliding plate 202 to retract. Then, under the restriction of the trapezoidal bar 203, the sliding plate 202 can move on the U-shaped support frame 201, thereby pulling the adsorbed corrugated paper upwards on the conveyor belt 3. After the corrugated paper is moved above the conveyor belt 3, the air pump 205 is activated to release the negative pressure between the hose 206 and the suction cup 207, thereby putting down the corrugated paper and completing the corrugated paper loading step.

[0047] Working principle: Before using the device, firstly, place the corrugated paper on the moving plate 5. Then, push the limiting plates 6 on both sides to apply pressure to the corrugated paper stack, ensuring that it is neatly stacked on the moving plate 5 and centered. At this time, start the servo motor 13, which drives pulley 14 to rotate. Through the belt 15, pulley 16 rotates synchronously, thereby causing the rotating disk 10 to rotate. The support column 11 rotates accordingly, driving the moving plate 5 to move upward, thus ensuring that the corrugated paper stack can move slowly upward. And through the pulling mechanism 2, when the top corrugated paper of the stack is in contact with the suction cup 20... When contact occurs, the air pump 205 is activated, and a negative pressure is generated in the space where the corrugated paper is in contact with the suction cup 207 through the hose 206, thereby adsorbing the corrugated paper. Subsequently, the electric telescopic rod 204 is activated, which drives the sliding plate 202 to retract. Under the restriction of the trapezoidal bar 203, the sliding plate 202 can move within the U-shaped support frame 201, thereby pulling the adsorbed corrugated paper upwards onto the conveyor belt 3.
