Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1-3 As shown, this application discloses a creasing fixture for explosion-proof paperboard, including a creasing assembly 2. The creasing assembly 2 is installed on a creasing machine 1. The creasing assembly 2 includes a support tube 201 and an installation tube 202. Two installation pieces 204 are installed at the bottom end of the installation tube 202. A creasing piece 217 is installed between the two installation pieces 204. A first tube body 205 is installed between the front ends of the two installation pieces 204. A steam pipe 206 is installed at the top end of the first tube body 205. A second tube body 207 is installed through the bottom end of the steam pipe 206. A humidifying shell 210 is installed at the bottom end of the second tube body 207. A side-penetrating component is installed in the center of the bottom end of the humidifying shell 210.

[0022] Driven by a motor, the front roller of the creasing machine 1 moves the cardboard toward the rear end. The lower crossbar at the rear of the creasing machine 1 rotates the support tube 201 under the drive of the motor. The support tube 201 supports the cardboard. The creasing plate 217 contacts the cardboard and presses out creases. Steam humidifies the cardboard through the steam pipe 206, the first pipe 205, the second pipe 207 and the humidifying shell 210 to prevent the crease from bursting during the creasing process.

[0023] like Figure 3 As shown, a limiting block 208 is installed at the connection between the second tube 207 and the first tube 205. A first spring 209 is installed between the top of the second tube 207 and the first tube 205. A vertical surface is provided on the side wall of the second tube 207. By providing the first spring 209, the second tube 207 can be prevented from falling out of the first tube 205. The first spring 209 can squeeze the second tube 207 downward, so that the humidifying shell 210 is close to the upper end of the cardboard. By providing a vertical surface on the side wall of the second tube 207, the second tube 207 can be prevented from rotating inside the first tube 205.

[0024] like Figure 2 As shown, the support tube 201 and the mounting tube 202 are mounted on the crossbar of the indentation machine 1 by bolts 203. The end of the bolt 203 is provided with a plane at the position of contacting the crossbar of the indentation machine 1. The positions of the support tube 201 and the mounting tube 202 can be adjusted on the crossbar of the indentation machine 1. The contact area of ​​the end of the bolt 203 with the plane of the crossbar of the indentation machine 1 can be increased, thereby improving the fixing effect.

[0025] like Figure 3 As shown, a first rotating roller 211 is installed at the front end of the humidifying shell 210. By setting the first rotating roller 211, the sliding friction between the humidifying shell 210 and the cardboard can be changed into rolling friction, thereby improving the smoothness of the cardboard movement.

[0026] like Figure 4As shown, the piercing assembly includes a second rotating roller 212. Several piercing needles 213 arranged in a ring are provided on the outer side of the second rotating roller 212 near the center. Mounting blocks 214 are movably connected to both ends of the second rotating roller 212. Mounting shells 215 are movably connected to the outer side of the mounting blocks 214. A second spring 216 is installed between the top of the mounting blocks 214 and the mounting shells 215. The mounting shells 215 are fixedly connected to the humidifying shells 210. The second spring 216 presses down on the mounting blocks 214, causing the second rotating roller 212 to contact the cardboard. The piercing needles 213 pierce the cardboard, making it easier for the cardboard to be wetted by water mist.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The implementation principle of the explosion-proof cardboard crease fixture in this application embodiment is as follows:

[0030] In use, the cardboard is placed on the support plate of the creasing machine 1. Driven by the rotating roller at the front of the creasing machine 1, the cardboard moves towards the rear end. The cardboard contacts the support tube 201 on the lower crossbar at the rear of the creasing machine 1. The lower crossbar at the rear of the creasing machine 1 drives the support tube 201 to rotate synchronously with the rotating roller at the front of the creasing machine 1. The cardboard passes under the humidifying shell 210. Steam acts on the upper end of the cardboard through the steam pipe 206, the first pipe body 205, the second pipe body 207 and the humidifying shell 210. The second spring 216 presses down the mounting block 214, which drives the second rotating roller 212 and the piercing needle 213 to contact the upper end of the cardboard and pierce the cardboard, making it easier for the cardboard to be wetted by water mist and further accelerating the humidification process. The first rotating roller 211 changes the sliding friction between the humidifying shell 210 and the cardboard into rolling friction, reducing the resistance when the cardboard moves. The creasing plate 217 contacts the cardboard and presses creases into the cardboard.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
