Description

Technical Field

[0001] The utility model relates to the technical field of paperboard deviation correction, in particular to a paperboard deviation correction device. Background Art

[0002] As an environmentally friendly and durable cardboard, when it is produced on an assembly line, whether it is cutting the cardboard or gluing multiple layers of cardboard, it is necessary to correct the cardboard first, so as to ensure the accuracy of the cardboard after processing and improve the quality of the cardboard. The existing cardboard correcting device has a variety of design structures, but there is a common problem that the edge of the cardboard may be damaged after correction.

[0003] For example, a Chinese utility model patent with announcement number CN214827524U discloses a correction conveying device for cardboard production. Although the scheme uses a second motor to push the movable block to move, indirectly driving the correction plate to move, so that the correction plate fits with both sides of the cardboard to achieve the purpose of correction, but when the cardboard and the correction plate fit together, if the correction plate actively approaches inward or the cardboard approaches the correction plate, when the cardboard moves too fast or the correction plate approaches too fast, it is possible to produce a violent impact effect on the edge of the cardboard. In fact, in the cardboard production workshop in the real scene, the cardboard transportation speed on the conveyor belt is generally high, so this correction method through positioning and collision may cause the cardboard edge to be twisted, deformed and damaged. Based on this, a correction device based on machine vision calculation is proposed, which mechanically imitates human fingers to apply friction to the upper surface of the cardboard to smooth the offset angle of the cardboard and finally achieve the purpose of correction.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1-Figure 2A cardboard correction device of the present embodiment comprises two positioning plates 1 and a fixed platform 6 above the two positioning plates 1, spring telescopic rods 11 are fixedly connected to the two sides of the fixed platform 6, a balance plate 14 is fixedly connected to the lower ends of the two spring telescopic rods 11, and rubber erasers 12 are fixedly connected to the two sides of the balance plate 14, respectively. A balance plate counterweight mechanism for tilting the balance plate 14 to one side is arranged on the lower side of the fixed platform 6, and a span adjustment mechanism for adjusting the span of cardboards of different widths is arranged on both sides of the fixed platform 6. A pulley translation mechanism is arranged on one side of the two positioning plates 1 to facilitate the correction device to correct the cardboards at different positions in the conveyor belt direction. The balance plate counterweight mechanism comprises a fixed plate 15 fixedly connected to the lower side of the fixed platform 6, and a first rocker 4 and a second rocker 8 are rotatably connected to one side of the fixed plate 15, and one end of the first rocker 4 is rotatably connected to a connecting plate 5 rotatably connected to one end of the second rocker 8. A lower push rod 13 cooperating with the upper side of the balance plate 14 is fixedly connected to the lower side of the connecting plate 5, and the span adjustment mechanism includes a plurality of telescopic rods 7 respectively fixedly connected to the two sides of the fixed platform 6, and one end of the plurality of telescopic rods 7 on both sides is respectively fixedly connected to the support plate 2, and a camera shooting mechanism for machine vision analysis of the offset of the conveyor belt cardboard is arranged on the lower side of the support plate 2, and a control mechanism for setting the descending height, time and left and right swinging speed of the lower push rod 13 is arranged on the side of the support plate 2 away from the fixed platform 6, the camera shooting mechanism includes a high-definition camera 3 fixedly connected to the lower side of the support plate 2, and the control mechanism includes an industrial control panel 9 arranged on one side of the support plate 2, and the lower sides of the two support plates 2 are fixedly connected with a positioning plate 1 cooperating with the upper side of the conveyor belt, and the lower sides of the two positioning plates 1 are provided with rollers 10, and a servo motor 16 fixedly connected to one side of the first rocker 4 is arranged on one side of the fixed plate 15.

[0025] Please combine Figure 3 As shown, when the bonded cardboard 17 needs to be sent to the cardboard bonding center for processing via the conveyor belt 18, the bonded cardboard 17 must be corrected first. At this time, the rubber eraser 12 is made of industrial composite rubber, which has good wear resistance and can increase the friction between the rubber eraser 12 and the upper side of the bonded cardboard 17, making the correction more sensitive. The contact surface of the rubber eraser 12 is rounded to avoid the problem of unstable contact with the bonded cardboard 17 when the rubber eraser 12 is tilted. The length of the spring telescopic rod 11 should meet the critical state that the balance board 14 and the two rubber erasers 12 are just suspended on the upper side of the cardboard, but not in contact in the natural state.

[0026] The implementation principle of a correction device for cardboard in the embodiment of the present application is as follows: the span of the correction device is first adjusted by the telescopic rod 7 to adapt to the width of the corresponding cardboard, the positioning plate 1 is docked with the edge of the conveyor belt, and the correction device is moved to a certain position of the conveyor belt by the roller 10 for correction. The servo motor 16 is started to push the first rocker 4 to swing, drive the connecting plate 5 and the lower push rod 13 to swing, so that the lower push rod 13 applies pressure to one side of the balance plate 14, the spring telescopic rod 11 is stretched and deformed, and the balance plate 14 is tilted. The rubber wiper 12 on the tilted side contacts the cardboard below, generating a backward friction force, which slows down the travel speed of the cardboard on the offset side, thereby achieving the correction effect.

[0027] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
