Description

Technical Field

[0001] The utility model relates to the technical field of crease devices, in particular to a multi-station crease device for cartons. Background Art

[0002] As the name implies, a cardboard crease device is a device or tool used to create creases on cardboard. It is usually used in packaging, printing and other industries to facilitate folding cardboard into various shapes. Different types of cardboard crease devices are suitable for different production needs and process requirements. When choosing a cardboard crease device, you need to consider factors such as the thickness, size, material, crease style and production batch of the cardboard to ensure that the right equipment is selected to meet specific production requirements.

[0003] During carton production, the cardboard needs to be creased before the cartons are assembled to facilitate subsequent folding into cartons. However, most existing cardboard crease devices use manual pushing for creases, and semi-automatic creases result in low crease efficiency. At the same time, the friction of the cardboard is large. When the upper cardboard is pushed, the friction can easily drive the lower cardboard into the device for creases, resulting in uneven crease depth or even failure to fold into cartons. What's worse, it may cause paper jams in the device and crease failure, affecting production efficiency. Utility Model Content

[0023] The scale groove 23 is arranged on the top surface of the processing table 1, and a slide groove 24 is provided on the top surface of the processing table 1. A contact plate 25 is slidably connected to the top surface of the processing table 1. A bolt 26 is penetrated and threadedly connected to the inner side of the contact plate 25. The contact plate 25 is slid and the bolt 26 is made to slide along the slide groove 24. After the contact plate 25 contacts the edge of the cardboard, the bolt 26 is tightened to fix the contact plate 25. The bolt 26 penetrates the slide groove 24. The inner side of the processing table 1 penetrates and is rotatably connected with a rotating shaft 1 21 and a rotating shaft 2 22. A limiting groove 27 is provided on the inner side of the processing table 1. A lifting rod 28 is penetrated and slidably connected to the inner side of the limiting groove 27. A baffle 29 is fixedly connected to the top surface of the lifting rod 28. After the lifting rod 28 moves downward, it will drive the pressing plate 210 to move downward together through the baffle 29, and the pressing plate 210 will rotate a certain distance after contacting the edge of the cardboard, and the pressing plate 210 will no longer press the cardboard, but will replace the baffle 29 to block the cardboard. The top surface of the baffle 29 is hinged with the pressing plate 210. When crease the cardboard, first loosen the bolt 26 to allow the contact plate 25 to slide, and then place the cardboard or cardboard stack to be creased on the surface of the processing table 1, adjust the position of the cardboard through the scale groove 23 and the position of the crease knife 6, and press the cardboard under the pressing plate 210. A torsion spring 211 is fixedly connected between the pressing plate 210 and the baffle 29. The second rotating shaft 22 is penetrated by a cam 213, and the cam 213 is fixedly connected to the second rotating shaft 22. When the cam 213 contacts the lifting rod 28, the lifting rod 28 is forced to slide downward along the limit groove 27 for a certain distance, and the second spring 212 will be compressed. The rotating shaft 22 penetrates and is fixedly connected with the rotating column 214, and the surface of the rotating column 214 penetrates and is slidably connected with the telescopic rod 215. The end of the telescopic rod 215 away from the rotating column 214 is fixedly connected with a rubber toggle block 216, and a spring 1 217 is fixedly connected between the rubber toggle block 216 and the rotating column 214. The bottom surface of the lifting rod 28 is fixedly connected with the spring 212, and when the rotating shaft 22 rotates, the cam 213 will be driven to rotate, and the cam 213 will hit the lifting rod 28 after one rotation. Since the lifting rod 28 penetrates the limiting groove 27, when the cam 213 hits the lifting rod 28, the lifting rod 28 is forced to slide down a certain distance along the limiting groove 27, and the spring 212 will be compressed. The end of the spring 212 away from the lifting rod 28 is fixedly connected to the inner side of the limiting groove 27. The rotating shaft 21 passes through a conveying roller 218, and the rotating shaft 22 drives the rotating column 214 to rotate. The rotating column 214 drives the rubber toggle block 216 to toggle the cardboard through the telescopic rod 215, so that the cardboard is brought between the conveying roller 218 and the crease knife 6, and is creased by the conveying of the conveying roller 218 and the crease knife 6. The conveying roller 218 is fixedly connected to the rotating shaft 1 21, and the ends of the rotating shaft 1 21 and the rotating shaft 2 22 located on the outer side of the processing table 1 are penetrated and fixedly connected with a transmission wheel 219.The transmission wheel 219 through which the rotating shaft 1 21 and the rotating shaft 2 22 pass is connected via a belt 220, and the output shaft of the motor 4 passes through the rotating shaft 1 21 and is fixedly connected. When the motor 4 is started, the output shaft of the motor 4 will drive the rotating shaft 1 21 to rotate, and when the rotating shaft 1 21 rotates, it will drive the rotating shaft 2 22 and the conveying roller 218 to rotate together through the transmission wheel 219 and the belt 220.

[0024] Based on the above embodiment, when crease the cardboard, first loosen the bolt 26 to allow the contact plate 25 to slide, and then place the cardboard boxes to be creased on the surface of the processing table 1, adjust the position of the cardboard by the position of the scale groove 23 and the crease knife 6, and press the cardboard under the pressing plate 210, and then slide the contact plate 25, and make the bolt 26 slide along the slide groove 24. After the contact plate 25 contacts the edge of the cardboard, tighten the bolt 26 to fix the contact plate 25, and then start the motor 4. The output shaft of the motor 4 will drive the rotating shaft 1 21 to rotate, and the rotating shaft 1 21 will drive the rotating shaft 22 and the conveying roller 218 to rotate together through the transmission wheel 219 and the belt 220 when rotating. When the rotating shaft 22 rotates, it will drive the cam 213 to rotate, and the cam 213 will contact the lifting rod 28 after rotating one circle. Since the lifting rod 28 passes through the limiting groove 27, the lifting rod 28 is forced to move when the cam 213 contacts the lifting rod 28. The lifting rod 28 will slide downward along the limit groove 27 for a certain distance, and the spring 212 will be compressed at the same time. After the lifting rod 28 moves downward, the baffle 29 will drive the pressure plate 210 to move downward together. After the pressure plate 210 hits the edge of the cardboard, it will rotate a certain distance, and the pressure plate 210 will no longer press the cardboard, but replace the baffle 29 to block the cardboard. At the same time, the rotating shaft 22 will drive the rotating column 214 to rotate, and the rotating column 214 drives the rubber toggle block 216 to toggle the cardboard through the telescopic rod 215, so that the cardboard is brought between the conveying roller 218 and the crease knife 6, and the cardboard is creased through the conveying of the conveying roller 218 and the crease knife 6. The cam 213 is used to release the limit of the baffle 29 and the pressure plate 210 on the cardboard, and then the rubber toggle block 216 is used to extract a single cardboard, so that automatic feeding can be realized while preventing the top cardboard from driving the next paper into the conveying roller 218 due to friction during feeding, so as to avoid uneven indentation depth or equipment jam due to cardboard misalignment or offset.

[0025] By setting up multiple workstations and stacking the cardboard on the processing table 1, automatic loading can be achieved, which greatly improves the work efficiency and can effectively enable the crease knife 6 and the conveyor roller 218 to stably crease the cardboard.

[0026] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit and concept of the present utility model are within the protection scope of the present utility model.
