Description

Technical Field

[0001] The utility model relates to a line contact device used for carton processing. Background Art

[0002] The line-touching device for carton processing is a processing technology that places the cardboard between the convex and concave cutters to collide with each other, thereby creating a crease on the cardboard. It has the advantages of good molding quality and high folding resistance at the crease. The existing line-touching device for carton processing usually uses an electric telescopic rod or a hydraulic device to control the periodic collision of the convex and concave cutters. However, in actual processing, even if there is no cardboard between the convex and concave cutters, the two will collide with each other, resulting in the convex and concave cutters being gradually worn out due to direct collision during long-term processing. Therefore, it is necessary to develop a line-touching device for carton processing to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0016] See also Figures 1 to 3The wire-touching device for carton processing shown in the figure comprises a U-shaped frame 11, a crossbeam 13 is slidably arranged between the two side walls of the U-shaped frame 11, an electric-controlled telescopic rod 12 is connected between the crossbeam 13 and the top wall of the electric-controlled telescopic rod 12, an infrared detector 14 is arranged on the front side of the crossbeam 13, a convex knife 15 is arranged on the lower side of the crossbeam 13, locking components 17 are arranged between the two sides of the convex knife 15 and the crossbeam 13, and a concave knife component 16 is arranged on the lower side of the crossbeam 13; the crossbeam 13 is controlled by the electric-controlled telescopic rod 12 to extend and retract. 3 is lifted and lowered, thereby controlling the convex blade 15 and the concave blade assembly 16 to collide with each other; the infrared detector 14 emits infrared rays to detect whether there is cardboard between the convex blade 15 and the concave blade assembly 16. When there is cardboard between the convex blade 15 and the concave blade assembly 16, the electric-controlled telescopic rod 12 is normally extended and retracted to complete the collision. When there is no cardboard between the convex blade 15 and the concave blade assembly 16, the electric-controlled telescopic rod 12 is powered off, thereby avoiding the convex blade 15 and the concave blade assembly 16 from directly colliding with each other, thereby protecting the convex blade 15 and the concave blade assembly 16 and extending their service life.

[0017] Furthermore, the concave knife assembly 16 includes a concave knife box 18, which is fixed between the two side walls of the U-shaped frame 11. A concave knife plate 19 is provided on the top of the concave knife box 18, and a groove 20 is provided on the concave knife plate 19; the groove 20 is located directly below the convex knife 15, and when the convex knife 15 collides with the concave knife assembly 16, the convex knife 15 and the groove 20 can be used to create a crease on the cardboard.

[0018] Further, the locking assembly 17 includes a locking sleeve rod 24, a locking inner rod 28 and a mounting plate 29, wherein the mounting plate 29 is fixed on the cross beam 13, one end of the locking inner rod 28 is fixed to the mounting plate 29, the locking sleeve rod 24 is arranged on one side of the locking inner rod 28, a telescopic groove 26 is arranged in the locking sleeve rod 24, the locking inner rod 28 is slidably connected to the telescopic groove 26, a spring 27 is connected between the locking inner rod 28 and the inner wall of the telescopic groove 26, a slot 23 is arranged at the end of the convex knife 15, the locking sleeve rod 24 is plugged into the slot 23, and a rubber ring 25 is arranged on the locking sleeve rod 24; the locking sleeve rod 24 is inserted into the slot 23 under the action of the spring 27, thereby locking the convex knife 15, and when replacing the convex knife 15, the rubber ring 25 is held to pull the locking sleeve rod 24 outward to separate the locking sleeve rod 24 from the slot 23.

[0019] Furthermore, a magnet plate 22 is provided on the top of the convex knife 15, and the magnet plate 22 is in contact with the bottom of the cross beam 13; the magnet plate 22 is adsorbed on the cross beam 13 by magnetic force, so as to further enhance the stability of the installation of the convex knife 15.

[0020] Furthermore, the concave blade plate 19 is made of aluminosilicate glass, and a light-absorbing coating 21 is provided at the bottom of the concave blade box 18; the concave blade plate 19 made of aluminosilicate glass can allow infrared rays to pass through while having good strength to cope with collisions; when there is cardboard between the convex blade 15 and the concave blade assembly 16, the infrared rays emitted by the infrared detector 14 are reflected by the cardboard, and the infrared detector 14 detects the reflected infrared rays, indicating that the cardboard is detected; when there is no cardboard between the convex blade 15 and the concave blade assembly 16, the infrared rays emitted by the infrared detector 14 pass through the concave blade plate 19 and are then absorbed by the light-absorbing coating 21, and the infrared detector 14 cannot detect the reflected infrared rays, indicating that no cardboard is detected.

[0021] The working principle of the utility model is that when the cardboard is touched, the infrared detector 14 is started, and when there is cardboard between the convex knife 15 and the concave knife assembly 16, the infrared detector 14 detects the infrared rays reflected by the cardboard, thereby controlling the electric control telescopic rod 12 to start extending, so that the crossbeam 13 is lowered, so that the convex knife 15 and the concave knife assembly 16 collide with each other, so that the convex knife 15 and the concave groove 20 collide with each other to form a crease on the cardboard; when there is no cardboard between the convex knife 15 and the concave knife assembly 16, the infrared detector 14 cannot detect the reflected infrared rays, thereby controlling the electric control telescopic rod 12 to be powered off, and the convex knife 15 and the concave knife assembly 16 do not collide with each other.

[0022] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
