Description

Technical Field

[0001] This utility model relates to the field of paper product bending technology, and in particular to a positioning device for bending paper products. Background Technology

[0002] A search revealed a Chinese patent with authorization number CN222116261U, which discloses a positioning device for bending paper products. The device includes a worktable and a positioning mechanism located inside the worktable. The positioning mechanism comprises a working component and a positioning component. By setting a limiting block, the paper product passes through the limiting block and is then inserted into a groove at one end of the positioning block. Then, according to the required bending length, the pressing blocks at both ends of the adjusting block are pressed. The pressing blocks cause the springs to compress, and the locking block slides out of its slot as the pressing blocks move. The adjusting block is then adjusted to a suitable position, the pressing blocks are released, the springs extend, the pressing blocks pop out, and the locking block re-engages into a new slot, aligning the limiting block with the bending point of the paper product and positioning the bending point.

[0003] The bending positioning device in the above patent has the following shortcomings: during the bending process of paper products, no limit is set for the surface of the paper products, which leads to the surface of the paper products bending due to the large force during the bending process, thus affecting the production quality of the paper products. Moreover, the paper products will also be displaced during the bending process, which will affect the bending accuracy. Therefore, the above problems need to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning device for bending paper products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning device for bending paper products includes a base with a receiving groove at one top end. A first conveying roller and a second conveying roller are rotatably connected inside the base, both horizontally positioned. The base contains a rotating mechanism for rotating the first and second conveying rollers, and a sliding mechanism for sliding the second conveying roller. A connecting box is fixedly connected to the top of the base, with inlets and outlets at both ends. A bending mechanism is located inside the connecting box. The sliding block allows for easy up-and-down sliding of a pressing plate during use, pressing the surface of the paper product. Further downward sliding of the sliding block rotates the bending plate via two support rods, facilitating bending of the paper product and improving the stability of the device during use.

[0007] Preferably, the rotating mechanism includes a synchronous belt, and a rotating shaft is sleeved inside both the first and second conveying rollers. The two rotating shafts are respectively inserted into both ends of the base. The synchronous belt is rotatably connected to one side of the base surface. The synchronous belt is provided with two synchronous pulleys inside. The two synchronous pulleys are respectively fixedly connected to one end of the two rotating shafts. A motor is installed on the other side of the base surface. The motor is fixedly connected to the rotating shaft at one end of the first conveying roller to limit the simultaneous rotation of the first and second conveying rollers, thereby facilitating the conveying of paper products. The sliding distance of the paper products can be controlled by the motor.

[0008] Furthermore, the sliding mechanism includes a second slider. An arc-shaped groove is formed through the interior of the base. The second conveying roller is slidably connected to the interior of the arc-shaped groove. There are two second sliders, each slidably connected to one end of the arc-shaped groove. The ends of the two second sliders are respectively in contact with the arc surface inside the arc-shaped groove. Both arc-shaped grooves are coaxially arranged with the first conveying roller. The ends of the second conveying roller are rotatably connected to the opposite sides of the two second sliders. A first spring is fixedly connected to the bottom of each of the two arc-shaped grooves. The top ends of the two first springs are fixedly connected to the bottom of the two second sliders. Connecting blocks are slidably connected to both sides of the symmetrical surface of the base. The two connecting blocks are fixedly connected to the surfaces of the two second sliders to restrict the sliding of the second conveying roller inside the base, thereby facilitating the sliding of the second conveying roller into the base during bending.

[0009] Preferably, two circular rollers are rotatably connected inside the connecting box. The two circular rollers cooperate with the first conveying roller and the second conveying roller respectively to adhere to the surfaces of the first conveying roller and the second conveying roller, thereby facilitating the conveying of paper products.

[0010] Furthermore, the bending mechanism includes a pressing plate, which is vertically slidably connected to the inside of the connecting box near the receiving slot. Vertical grooves are vertically formed on both sides of the surface of the connecting box. First sliders are fixedly connected to both ends of the pressing plate, and two first sliders are slidably connected to the two vertical grooves respectively. A cutting groove is provided at the top of the base, located at the higher end of the receiving slot, and the surface of the cutting groove is inclined. Top rods are vertically slidably connected to both sides of the surface of the connecting box. Two top rods are fixedly connected to the bottom of two first sliders respectively, and the two top rods cooperate with two connecting blocks respectively. A fixing box is fixedly connected to the top of the pressing plate, and a sliding block is vertically slidably connected inside the fixing box. Two opposing sides are located inside the surface of the fixing box. Each side has vertically formed limiting grooves, and each of the two limiting grooves has a slidably connected limiting block. The two limiting blocks are respectively fixedly connected to both ends of the slide surface. A second spring is provided at the bottom of the fixed box, and the tops of the two second springs are fixedly connected to the bottom of the slide. Two hydraulic telescopic cylinders are installed on the top of the slide, and the tops of the two hydraulic telescopic cylinders are fixedly connected to the top of the connecting box. A bending plate is rotatably connected to one side of the pressing plate surface. The bending plate cooperates with the cutting groove. Two support rods are rotatably connected to the top of the bending plate, and the tops of the two support rods are rotatably connected to the slide surface. These support rods are used to limit the up and down sliding of the pressing plate and also drive the bending plate to rotate, thereby facilitating the bending of paper products and controlling the rotation angle of the bending plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. Driving two hydraulic telescopic cylinders causes the slide to slide downwards. Simultaneously, with the setting of two second springs, the fixing box and the pressing plate slide downwards at the same time. Then, the pressing plate first presses the surface of the paper product. At the same time, with the setting of two first sliders and two top rods, it presses the top of the two connecting blocks, causing the two second sliders and the second conveying roller to slide downwards, thereby preventing bending of the paper product surface. After the pressing plate presses the surface of the paper product, it can slide the slide downwards in sequence. At this time, the slide slides into the fixing box. At this time, with the connection of two support rods, the bending plate will rotate, which can bend the surface of the paper product, making the paper product more stable during the bending process.

[0013] 2. During the bending process of stone products, the downward sliding distance of the slide can be controlled, and the angle of rotation of the bending plate can be controlled through the two support rods, thereby controlling the bending angle and improving the effectiveness of the device.

[0027] Working Principle: In actual use, the sliding block 7 allows the pressing plate 3 to slide up and down easily, pressing the surface of the paper product.

Connected by the synchronous belt 6 and two synchronous pulleys 61, the other rotating shaft 52 and the second conveyor roller 51 rotate. With the two circular rollers 23 in place, the paper product is conveyed. The rotation of the first and second conveyor rollers 51 can be controlled to transport the paper product to the cutting groove 12 where bending is required. Then, the two hydraulic telescopic cylinders 73 drive the sliding block 7 downwards, while the two second springs 72... Under the current setting, the fixing box 33 and the pressing plate 3 will slide downwards simultaneously. Then, the pressing plate 3 will press the surface of the paper product first. At the same time, with the setting of the two first sliders 31 and the two top rods 32, the tops of the two connecting blocks 56 will be pressed, causing the two second sliders 54 and the second conveying roller 51 to slide downwards, thereby preventing bending of the paper product surface. After the pressing plate 3 presses the surface of the paper product, it can slide the slide block 7 downwards in sequence. At this time, the slide block 7 will slide into the fixing box 33. At this time, with the connection of the two support rods 74, the bending plate 4 will rotate, which can bend the surface of the paper product. At the same time, the downward sliding distance of the slide block 7 can be controlled, and the rotation angle of the bending plate 4 can be controlled, thereby controlling the bending angle. After completion, the slide block 7 and the pressing plate 3 will slide upwards. Then, with the rotation of the first conveying roller 5 and the second conveying roller 51, the paper product will be conveyed to the receiving groove 11 through another inlet 21 on the surface of the connecting box 2.
