Description

Technical Field

[0001] This application relates to the field of paper, and in particular to a calibration line cutting identification mechanism for longitudinal cutting of cardboard. Background Technology

[0002] A cardboard slitting machine is a specialized piece of equipment used to cut large rolls of cardboard longitudinally. It is mainly used in the production of cartons, boxes, and packaging materials, as well as in the printing and papermaking industries. It is suitable for the precise cutting of materials such as corrugated cardboard, cardboard, and kraft paper.

[0003] Common cardboard slitting machines install marking recognition cameras or sensors in the cutting area. This requires manual movement of the camera and manual confirmation that the camera is aligned with a specific cutting point on the cardboard to monitor the cutting point position. When it is necessary to change orders for cutting, the cardboard cut to different sizes will be different. After each order is completed, the worker needs to readjust the camera position. When there are different cardboard sizes in multiple orders and the quantity of each size is small, the camera position needs to be frequently stopped and adjusted, which reduces the efficiency of order changeover and results in low production efficiency and high production costs for small batches of fragmented orders. Utility Model Content

[0004] To reduce the production cost of small-batch orders, this application provides a calibration line cutting identification mechanism for cardboard longitudinal cutting.

[0005] This application provides a calibration line cutting and identification mechanism for longitudinal cutting of cardboard, which adopts the following technical solution:

[0006] A marking line cutting and identification mechanism for longitudinal slitting of order cardboard includes a marking line recognition camera and a mounting base. The marking line recognition camera is slidably mounted on the mounting base, and the sliding direction of the marking line recognition camera is perpendicular to the paper running direction of the cardboard. It also includes a sliding drive mechanism that drives the marking line recognition camera to slide. The sliding drive mechanism is connected to a production management system. When the cardboard runs, there are pre-set marking lines on the paper surface. The sliding drive mechanism drives the marking line recognition camera to follow the marking lines. The marking line recognition camera transmits signals to the production management system, and the production management system drives the cutting blade to cut the paper according to the marking line position.

[0007] By adopting the above technical solution, the mounting base is set on the paper feeding table. When the paperboard is feeding, there are pre-set markings on the paper surface. When the paperboard is on the paper feeding table, the sliding drive mechanism drives the marking recognition camera to slide on the mounting base. When the marking recognition camera recognizes the marking, it stops sliding. The marking recognition camera recognizes the marking and transmits it to the production management system. At the same time, the two sides of the paperboard are cut. The production management system drives the cutting blade to cut the paper according to the marking position. The marking recognition camera recognizes the marking and causes the cutting blade to cut the paper according to the marking position. The control system uses the sliding drive mechanism to make the marking recognition camera follow the marking. The markings are different for different sizes of orders. When changing orders, the control system uses the sliding drive mechanism to drive the marking recognition camera to slide and follow the marking again. There is no need for manual adjustment of the marking recognition camera, which reduces the production cost of small batch orders.

[0008] Optionally, the mounting base is provided with a guide rail, and a sliding seat is slidably connected to the guide rail, with the marking recognition camera mounted on the sliding seat.

[0009] By adopting the above technical solution, the guide rail ensures stable connection of the sliding seat, and the marking recognition camera is installed on the sliding seat, making installation convenient.

[0010] Optionally, the sliding drive mechanism includes a motor and two pulleys. The two pulleys are rotatably disposed on both sides of the mounting base along its length. The motor is disposed on one side of the mounting base. The output end of the motor is coaxially fixed to the pulleys. A belt is connected between the two pulleys. The sliding base is connected to the side wall of the belt. The motor drives the pulleys to rotate, and the rotation of the belt causes the sliding base to slide along the length of the guide rail.

[0011] By adopting the above technical solution, the motor drives the pulley to rotate, and the belt rotation causes the sliding seat to slide, which is convenient for installation and allows the sliding seat to slide back and forth along the mounting base.

[0012] Optionally, the sliding seat is provided with a connecting assembly, which includes a first connecting rod and a second connecting rod, as well as a connecting bolt and an adjusting bolt. The first connecting rod is mounted on the sliding seat by the connecting bolt, and the second connecting rod is mounted at the end of the first connecting rod away from the sliding seat by the adjusting bolt. The marking recognition camera is mounted at the end of the second connecting rod away from the first connecting rod.

[0013] By adopting the above technical solution, the connecting components make it easy to raise the height of the road marking recognition camera. The first connecting rod and the second connecting rod are adjustable by connecting bolts and adjusting bolts, and the height of the road marking recognition camera can be adjusted as needed.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. The control system uses a sliding drive mechanism to make the road marking recognition camera always follow the road marking. When changing orders, the control system uses the sliding drive mechanism to make the road marking recognition camera slide and follow the road marking again. There is no need to manually adjust the road marking recognition camera, which reduces the production cost of small batch orders.

[0016] 2. The guide rail ensures stable connection of the sliding seat;

[0017] 3. The sliding seat is moved by the pulley and belt, which makes installation convenient. The sliding seat can slide back and forth along the mounting base. Attached Figure Description

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] This application discloses a calibration line cutting identification mechanism for longitudinal cutting of cardboard. (Refer to...) Figure 1 , Figure 2 , Figure 3A cardboard longitudinal cutting and identification mechanism includes a marking recognition camera 1 and a mounting base 2. A guide rail 41 is fixed on the mounting base 2, and a sliding seat 42 is slidably connected to the guide rail 41. The marking recognition camera 1 is fixed on the sliding seat 42, and the sliding direction of the sliding seat 42 is perpendicular to the paper running direction of the cardboard. The cardboard longitudinal cutting and identification mechanism also includes a sliding drive mechanism 3 that drives the sliding seat 42 to slide. When the cardboard is running, there are pre-set markings on the paper surface. The marking recognition camera (1) recognizes the markings and positions the markings at the center of the marking recognition camera (1). If the marking recognition camera (1) does not recognize the markings, the marking recognition camera (1) transmits a signal to the production management system. The production management system drives the sliding drive mechanism (3) to move the marking recognition camera (1) until it recognizes the markings. The marking recognition camera (1) recognizes the markings and transmits the signal to the production management system. The production management system drives a cutting blade (not shown in the figure) to cut the paper according to the marking position.

[0025] Reference Figure 3 , Figure 4 The sliding drive mechanism 3 includes a motor 31 and two pulleys 32, both of which are rotatably connected to opposite sides of the mounting base 2 along its length. The motor 31 is fixed to one side of the mounting base 2, and its output end is coaxially fixed to the pulleys 32. A belt 43 connects the two pulleys 32, and the sliding base 42 is fixed to the side wall of the belt 43. The motor 31 drives the pulleys 32 to rotate, and the rotation of the belt 43 causes the sliding base 42 to slide along the length of the guide rail 41.

[0026] Reference Figure 1 , Figure 2 , Figure 4 A connecting assembly 5 is provided on the sliding seat 42, including a first connecting rod 51 and a second connecting rod 52. A cardboard longitudinal cutting and marking line identification mechanism further includes a connecting bolt 6 and an adjusting bolt 7. The first connecting rod 51 is fixed to the sliding seat 42 by the connecting bolt 6. Damping pads (not shown in the figure) are fixed on both sides of the first connecting rod 51. When the first connecting rod 51 is fixed to the sliding seat 42, the damping pads abut against the inner wall of the sliding seat 42. The second connecting rod 52 is fixed to the end of the first connecting rod 51 away from the sliding seat 42 by the adjusting bolt 7. A fastening nut 8 is bolted to the end of the adjusting bolt 7 near the second connecting rod 52. The marking line identification camera 1 is fixed to the end of the second connecting rod 52 away from the first connecting rod 51. When the height of the marking line identification camera 1 needs to be adjusted, the height of the marking line identification camera 1 is finely adjusted by the connecting bolt 6. After adjustment, the connecting bolt 6 is retightened.

[0027] The implementation principle of the cardboard longitudinal cutting and identification mechanism according to this application embodiment is as follows: The mounting base 2 is fixed on the paper feeding table. The height of the marking recognition camera 1 is finely adjusted by connecting bolts 6. Markings are pre-set on the paper surface during paper feeding. When the cardboard is on the paper feeding table, the motor 31 drives the pulley 32 to rotate, causing the sliding seat 42 to slide on the mounting base 2. When the marking recognition camera 1 identifies the marking, the sliding seat 42 stops sliding, and the marking recognition camera 1 stops at the marking and takes a picture. The production management system drives the cutting blade to cut the paper according to the marking position based on the captured image. The marking recognition camera 1 achieves paper cutting by recognizing the markings. The cutting blades are symmetrically positioned, and their positions remain unchanged as they move simultaneously along the marking line. The production management system can pre-set the distance between the cutting blades and the marking line, or it can make the cutting blades cut along the marking line, depending on the situation. The production management system uses the sliding drive mechanism 3 to keep the marking line recognition camera 1 aligned with the marking line. Different sizes of orders have different marking lines. When changing orders, the production management system issues a command to drive the motor 31, and the marking line recognition camera 1 re-recognizes the marking line. There is no need for manual adjustment of the marking line recognition camera 1. The cutter cuts along the cardboard marking line, which increases the speed of order changeover and reduces the production cost of small batch orders.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
