INVENTION CONTENTS

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an easily adjustable creasing device for a paper slitting machine. This solves the problem that in the current traditional paper slitting machine creasing device, the cardboard is placed on the surface of the conveyor belt for creasing. However, since the middle area of ​​the conveyor belt is suspended, the cardboard is prone to downward movement and bending due to uneven force when the creasing roller or pressing roller presses down. In addition, conventional creasing rollers only creasing one side of the cardboard. When there is a need to creasing both sides of the cardboard at the same time, for example, in the production process of corrugated boxes, sometimes it is necessary to creasing both sides of the cardboard to enhance the load-bearing capacity, sealing performance, or aesthetic appearance of the box. Such single-sided creasing rollers cannot meet the technical requirements of the double-sided creasing process.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a pressure device for an easily adjustable paper slitting machine is designed, including a device base plate. A first fixing plate and a second fixing plate are respectively fixed at the front and rear ends of the top of the device base plate. A drive motor is installed at the front end of the first fixing plate. A threaded rod is connected to the rear end of the drive motor. The rear end of the threaded rod passes through two first moving blocks and is rotatably connected to a bearing. The bearing is installed on the surface of the second fixing plate. Opposite threads are provided at the front and rear ends of the surface of the threaded rod. The opposite threads are connected to the threaded holes in the first moving blocks. A pressure assembly is provided on the outside of the first moving blocks.

[0007] Preferably, the pressure assembly includes a support plate, a connecting strip, a second moving block, a first telescopic cylinder, a concave plate, a connecting rod, a bearing, and a pressure roller.

[0008] Preferably, the connecting strip is fixed to one end of the top of the first moving block, and a second moving block is fixed to the top of the connecting strip. A limit rod passes through the interior of the second moving block, and the limit rod is installed at the bottom of the top plate of the device.

[0009] Preferably, both sides of the first and second movable blocks are provided with support plates. A first telescopic cylinder is installed on the top of the support plate. A concave plate is fixed on the top of the first telescopic cylinder. A connecting rod is provided inside the concave plate. A pressure roller passes through the outside of the connecting rod, and the position of the pressure roller and the connecting rod is fixed. The front end of the connecting rod passes through the concave plate and is connected to a synchronous motor. The synchronous motor is installed on the surface of the concave plate.

[0010] Preferably, both sides of the first and second movable blocks are provided with grooves, and a second telescopic cylinder is installed at one end of the groove, with a support plate fixed at one end of the second telescopic cylinder extending out of the groove.

[0011] Preferably, a support rod is fixed at each of the four corners of the top of the device base plate, and a device top plate is fixed at the top of the support rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a first moving block, a second moving block, and a first telescopic cylinder. The first telescopic cylinder mounted on the first and second moving blocks simultaneously drives multiple pressure rollers to perform creasing operations on cardboard. Furthermore, multiple synchronous motors ensure that these pressure rollers rotate synchronously, allowing them to directly move the cardboard while creasing, achieving simultaneous creasing and conveying. This eliminates the need for a separate conveyor belt, integrating creasing and conveying functions into one unit. Moreover, because corresponding pressure rollers are positioned at both the top and bottom of the device, creasing can be performed on both sides of the cardboard simultaneously, making the device more efficient. The addition of double-sided creasing functionality solves the problem of traditional paper slitting machine creasing devices where the cardboard is placed on the conveyor belt surface for creasing. However, because the middle area of ​​the conveyor belt is suspended, the cardboard is prone to shifting and bending due to uneven force when the creasing or pressing rollers press down. In addition, conventional creasing rollers only creasing one side of the cardboard. When there is a need to creasing both sides of the cardboard simultaneously, such as in the production of corrugated boxes, sometimes double-sided creasing is required to enhance the load-bearing capacity, sealing performance, or aesthetic appearance of the boxes. Such single-sided creasing rollers cannot meet the technical requirements of double-sided creasing.

[0014] 2. This utility model, through the combination of a threaded rod, a second telescopic cylinder, and a support plate, not only allows the threaded rod to rotate using a drive motor, but also uses the opposite threaded walls on the surface of the threaded rod to simultaneously move multiple first and second moving blocks, thereby achieving adjustment of the longitudinal spacing between the pressure rollers. Furthermore, by utilizing the second telescopic cylinder, the support plate and pressure rollers can be moved, enabling adjustment of the lateral spacing between the pressure rollers, thus increasing the adjustability of the device.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A crease clamping device for an easily adjustable paper slitting machine, see [link / reference] Figures 1 to 3The device includes a base plate 1, with a first fixing plate 2 and a second fixing plate 201 fixed at the front and rear ends of the top of the base plate 1, respectively. A drive motor 202 is installed at the front end of the first fixing plate 2, and a threaded rod 205 is connected to the rear end of the drive motor 202. The rear end of the threaded rod 205 passes through two first moving blocks 203 and is rotatably connected to a bearing 208. The bearing 208 is installed on the surface of the second fixing plate 201. The front and rear ends of the threaded rod 205 have opposite threads, which are connected to the screw holes 204 in the first moving blocks 203. A pressure assembly is provided on the outside of the first moving blocks 203. First, the cardboard to be processed is passed between multiple pressure rollers 214 arranged vertically. Then, multiple pressure rollers on the device are activated. When the first telescopic cylinder 210 extends, it pushes the concave plate 211 and the pressure roller 214 toward the cardboard, thereby pressing the upper and lower surfaces of the cardboard. At the same time as the cardboard is pressed, multiple synchronous motors 213 are started. The synchronous motors 213 are permanent magnet synchronous motors (PMSM), which can provide high-precision position control and speed control. When the synchronous motors 213 are started, they drive the connecting rod 212 to rotate synchronously. Since all synchronous motors 213 are coordinated by the controller, the rotation of the connecting rod 212 is synchronous, ensuring that all pressure rollers 214 rotate at the same speed and direction. The rotation of the connecting rod 212 then drives the pressure rollers 214 to rotate. Because the pressure roller 214 is in close contact with the cardboard, the rotation of the pressure roller 214 will cause friction to move the cardboard to one side. During the movement of the cardboard, the pressure rollers 214 in the upper and lower positions simultaneously perform creasing on the front and back sides of the cardboard. This solves the problem in the traditional paper slitting machine creasing device, where the cardboard is placed on the surface of the conveyor belt for creasing. However, since the middle area of ​​the conveyor belt is suspended, when the creasing roller or pressing roller 214 presses down, the cardboard is prone to downward movement and bending due to uneven force. In addition, conventional creasing rollers only perform creasing on one side of the cardboard. When there is a need to creasing both sides of the cardboard at the same time, for example, in the production process of corrugated boxes, sometimes in order to enhance the load-bearing capacity, sealing performance or appearance of the box, it is necessary to creasing both sides of the cardboard. Such single-sided creasing rollers cannot meet the technical requirements of double-sided creasing.

[0021] It is important to note that the synchronization of the synchronous motor 213 is achieved through a controller. The controller typically includes a main controller (such as a PLC or motion controller) and multiple motor drivers. The main controller sends precise control signals to each motor driver, instructing them to drive the synchronous motor 213 at the same speed and direction. The motor drivers adjust the current and voltage of the motor according to the received control signals, thereby achieving precise speed and position control. Through this precise synchronization control mechanism, all pressure rollers 214 can rotate at the same speed and direction, ensuring the stability and consistency of the cardboard during the pressing process.

[0022] For details, see Figure 1 and Figure 2 The pressure assembly includes a support plate 209, a connecting strip 206, a second moving block 207, a first telescopic cylinder 210, a concave plate 211, a connecting rod 212, a bearing 208, and a pressure roller 214.

[0023] Further, see Figure 1 and Figure 2 The connecting strip 206 is fixed to one end of the top of the first moving block 203. The top of the connecting strip 206 is fixed with a second moving block 207. A limit rod 215 passes through the inside of the second moving block 207. The limit rod 215 is installed at the bottom of the top plate 102 of the device.

[0024] It is worth noting that, see Figure 1 and Figure 2 Both sides of the first moving block 203 and the second moving block 207 are provided with support plates 209. The top of the support plate 209 is equipped with a first telescopic cylinder 210. The top of the first telescopic cylinder 210 is fixed with a concave plate 211. A connecting rod 212 is provided inside the concave plate 211. A pressure roller 214 passes through the outside of the connecting rod 212, and the position of the pressure roller 214 and the connecting rod 212 is fixed. The front end of the connecting rod 212 passes through the concave plate 211 and is connected to a synchronous motor 213. The synchronous motor 213 is installed on the surface of the concave plate 211.

[0025] It is worth noting that, see Figure 3Both sides of the first moving block 203 and the second moving block 207 are provided with grooves 3. A second telescopic cylinder 301 is installed at one end of the groove 3. A support plate 209 is fixed at one end of the second telescopic cylinder 301 that extends out of the groove 3. When it is necessary to adjust the longitudinal spacing of the pressure roller 214, the first motor can be started. The first motor drives the threaded rod 205 to rotate. Since the threaded rod 205 has threads in opposite directions, during the rotation, the two first moving blocks 203 will move in opposite directions along the threaded rod 205. When the two first moving blocks 203 move, they will drive the connecting strip 206 to move together. The connecting strip 206 further drives the second moving block 207 to slide along the limiting rod 215. While the first moving block 203 and the second moving block 207 are moving, they work together to move the pressure roller 214, thereby adjusting the longitudinal spacing of the pressure roller 214. When it is necessary to adjust the lateral spacing of the pressure roller 214, the second telescopic cylinder 301 can be activated. When the second telescopic cylinder 301 extends or retracts, it will drive the support plate 209 to move. The support plate 209 fixes the first telescopic cylinder 210, the concave plate 211, and the pressure roller 214. Therefore, as the support plate 209 moves, the first telescopic cylinder 210, the concave plate 211, and the pressure roller 214 will also move together, thereby adjusting the lateral spacing of the pressure roller 214.

[0026] It is worth mentioning that, see Figure 1 The top four corners of the device base plate 1 are all fixed with support rods 101, and the top plate 102 of the device is fixed to the top of the support rods 101.

[0027] When using a crease clamping device of an easily adjustable paper slitting machine, firstly, the cardboard to be processed is passed between multiple pressure rollers 214 arranged vertically. Then, multiple first telescopic cylinders 210 on the device are activated. When the first telescopic cylinders 210 extend, they push the concave plate 211 and the pressure rollers 214 toward the cardboard, thereby pressing the upper and lower surfaces of the cardboard. At the same time as the cardboard is pressed, multiple synchronous motors 213 are activated. The synchronous motors 213 are permanent magnet synchronous motors (PMSM), which can provide high-precision position control and speed control. When the synchronous motors 213 are activated, they drive the connecting rods 212 to rotate synchronously. Since all synchronous motors 213 are coordinated by the controller, the rotation of the connecting rods 212 is synchronous, ensuring that all pressure rollers 214 rotate at the same speed and direction. The rotation of the connecting rods 212 then drives the pressure rollers 214 to rotate. Because the pressure roller 214 is in close contact with the cardboard, the rotation of the pressure roller 214 will cause friction to move the cardboard to one side. During the movement of the cardboard, the pressure rollers 214 at the upper and lower positions simultaneously perform creasing on the front and back sides of the cardboard. Since the threaded rod 205 has threads in opposite directions, during the rotation, it will cause the two first moving blocks 203 to move in opposite directions along the threaded rod 205. When these two first moving blocks 203 move, they will drive the connecting strip 206 to move together. The connecting strip 206 further drives the second moving block 207 to slide along the limiting rod 215. While the first moving block 203 and the second moving block 207 are moving, they work together to move the pressure roller 214, thereby adjusting the longitudinal spacing of the pressure roller 214. When it is necessary to adjust the lateral spacing of the pressure roller 214, the second telescopic cylinder 301 can be activated. When the second telescopic cylinder 301 extends or retracts, it will drive the support plate 209 to move. The support plate 209 fixes the first telescopic cylinder 210, the concave plate 211, and the pressure roller 214. Therefore, as the support plate 209 moves, the first telescopic cylinder 210, the concave plate 211, and the pressure roller 214 will also move together, thereby adjusting the lateral spacing of the pressure roller 214.
