[0006] Furthermore, the locking part includes a compression assembly installed within the connecting plate; and a pressure application assembly disposed within the connecting plate, the pressure application assembly being used to provide force for the locking function of the compression assembly.

[0007] Furthermore, the rotating assembly includes two brackets fixedly connected to the bottom of the printing machine body. A bidirectional threaded rod is rotatably connected to the inner wall of each bracket. The bidirectional threaded rod passes through the right-side bracket and two guide blocks. The outer wall of the bidirectional threaded rod is threadedly connected to the two guide blocks. The bidirectional threaded rod passes through a connecting plate and is rotatably connected to the connecting plate. A handle is fixedly connected to the outer wall of the bidirectional threaded rod. A protective component is provided outside the bidirectional threaded rod. The handle is located to the right of the right-side bracket. The protective component includes several telescopic protective sleeves fitted onto the outer wall of the bidirectional threaded rod. The side of each telescopic protective sleeve closest to the two guide blocks is fixedly connected to the two guide blocks. Four telescopic protective sleeves are provided. The two middle telescopic protective sleeves, with their sides close to each other, are fixedly connected to the connecting plate.

[0011] This utility model has the following beneficial effects: 1. By setting an adjustment section, when in use, after the printed cardboard is discharged from the printing machine body, it moves between two guide blocks under the action of several hinge rods one and several hinge rods two. After being guided by the guide blocks, it falls neatly on the top of the carrier plate. When a large number of cardboards accumulate, the printing machine body is closed, the cover door is opened, the carrier plate is pulled to slide in the chute, the cardboard stack is removed, the empty carrier plate is inserted back into the connecting plate, the cover door is closed, and the printing machine body can be started to continue production. It can guide the printed cardboard through the guide plate and multiple hinge rods, so that it is stacked in a relatively neat posture, which facilitates subsequent collection. At the same time, the distance between the two guide blocks can also be adjusted to accommodate cardboard of various sizes. 2. By setting a locking part, after adjustment, when different sizes of cardboard need to be adapted, pull handle two to drive the rotating shaft to rotate inside bracket two. The spiral spring rewinds and generates elastic force, moving handle two away from the extrusion block. The spring force drives the extrusion block away from the extrusion roller. Rotating handle one drives the bidirectional threaded rod to rotate. Under the protection of the telescopic protective sleeve, the bidirectional threaded rod drives the two guide blocks to move closer to each other. Hinged rod one and hinged rod two maintain the guiding effect. After adjustment, handle two resets with the assistance of the spiral spring force. The extrusion block slides along the limit rod and squeezes the spring. The extrusion block tightly presses against the extrusion roller to prevent the bidirectional threaded rod from rotating on its own. This locks the bidirectional threaded rod, preventing it from rotating on its own during device use, thereby maintaining the stability of the component position.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

By setting the locking part 3, the bidirectional threaded rod 222 can be locked to prevent the bidirectional threaded rod 222 from rotating during the use of the device, thereby maintaining the stability of the component position.

[0020] A specific application of this embodiment is as follows: During use, the raw material can be poured into the printing press body 101, and then the printing press body 101 can be started to print on the raw material of the packaging box. After printing, the cardboard will be discharged from the discharge port of the printing press body 101, i.e., moved below the cover door 102. At this time, the cardboard will move between two guide blocks 214 under the action of several hinge rods 215 and several hinge rods 216, and fall relatively neatly on the top of the support plate 213 under the guidance of the two guide blocks 214. After a significant amount of cardboard has accumulated on top of plate 213, the printing press body 101 can be closed. Then, the cover door 102 can be opened, and the support plate 213 can be pulled to slide within the two slide grooves 212. Once the cardboard is exposed along with the support plate 213, it can be removed. The empty support plate 213 can then be inserted back into the connecting plate 211, and the cover door 102 can be closed. The printing press body 101 can then be restarted to continue production. When the size of the cardboard to be printed changes, the distance between the two guide blocks 214 can be adjusted to adapt it. This is done by pulling the handle 324 to move the guide block. The rotating shaft 323 rotates within the two supports 321. At this time, both spiral springs 322 coil and generate elastic force. The side of the handle 324 closest to the extrusion block 312 moves away from the extrusion block 312. Under the elastic force of the spring 314, the unrestrained extrusion block 312 is moved away from the extrusion roller 311. Then, the handle 223 can be rotated to rotate the bidirectional threaded rod 222. When the bidirectional threaded rod 222 rotates, it is protected by several telescopic protective sleeves 224, causing the two guide blocks 214 to move closer to each other. At this time, the sliding connection of several hinge rods 215 and 216 will ensure the guiding effect. After the adjustment is completed, the rotation of the bidirectional threaded rod 222 can be stopped, and the handle 324 can be pushed back to its original position with the help of the spring force of the spiral spring 322. At this time, the handle 324 will squeeze the pressing block 312, making it slide on the limit rod 313, and squeeze the spring 314 to accumulate elastic force. When the handle 324 is fully reset, the pressing block 312 will press tightly against the pressing roller 311 to prevent the bidirectional threaded rod 222 from rotating during use.
