[0030] The pressing plate 206 is located above the air bag 207, the extension end of the pressing plate 206 penetrates through the T-shaped opening 205, the air bag 207 is compressed by pressing the pressing plate 206, then the extension end of the pressing plate 206 is deflected into the horizontal end of the T-shaped opening 205, so that the air bag 207 cannot extrude the pressing plate 206 upward, most of the air in the air bag 207 is discharged through the gas conveying pipe 203, then the square box paper pulp product is inverted and placed on the mold 202, the size of the mold 202 is consistent with the size of the paper pulp product, the upper end of the gas conveying pipe 203 is flush with the top of the mold 202, then the extension end of the pressing plate 206 is deflected into the vertical end of the T-shaped opening 205, at this time the air bag 207 is pushed upward by the natural elasticity of the pressing plate 206, and a certain negative pressure is formed in the air bag 207 and the gas conveying pipe 203, so that the paper pulp product is adsorbed on the mold 202;

[0031] Subsequently, cutting is performed, the cross electric slide rail 104 is lowered by the electric telescopic cylinder 103, the cross electric slide rail 104 can drive the servo motor 105 to move in the X and Y planes, the servo motor 105 drives the cutting blade 106 to cut the four sides of the paper pulp product, and the paper pulp product is cut in the middle, the top of the paper pulp product is tightly attached to the mold 202 by the air bag 207 and the air conveying pipe 203, so as to prevent tearing caused by the interference of the cutting blade 106, after cutting is completed, the cross electric slide rail 104 is raised by the electric telescopic cylinder 103, then the pressing plate 206 is pressed to the limit, the remaining air in the air bag 207 is discharged through the air conveying pipe 203, so that the air conveying pipe 203 no longer adsorbs the paper pulp product and blows it upward, so as to facilitate the worker to take out the cut paper pulp product from the mold 202, after taking out, the air bag 207 inhales air through the air conveying pipe 203 and expands to recover, and the pressing plate 206 is automatically raised and reset by the expansion of the air bag 207.

[0032] In addition, the inner wall of the T-shaped opening 205 is provided with a rounded corner, one side of the inner wall of the T-shaped opening 205 is fixedly connected with a rubber block 208, the side wall of the cylinder 204 is fixedly connected with a limiting block 209, and the top of the pressing plate 206 is slidably provided with a sliding block 210.

[0033] The rounded corner is located at the connection between the horizontal end and the vertical end of the top of the T-shaped opening 205, in the process of pressing down, the extending end of the pressing plate 206 is quickly moved into the horizontal end of the T-shaped opening 205 by applying force to the horizontal end of the T-shaped opening 205, so as to facilitate the extending end of the pressing plate 206 to be quickly moved into the horizontal end of the T-shaped opening 205, the position of the rubber block 208 corresponds to the horizontal end of the T-shaped opening 205, in the process of pressing down the pressing plate 206, the rubber block 208 can provide resistance to the pressing plate 206 to remind the user to deflect it into the horizontal end of the T-shaped opening 205. When the extending end of the pressing plate 206 is deflected into the horizontal end of the T-shaped opening 205, the thumb pushes the sliding block 210 to move towards the limiting block 209, so that the limiting block 209 limits the sliding block 210, at this time the pressing plate 206 cannot be deflected horizontally to avoid accidental contact with the pressing plate 206 causing the pressing plate 206 to be deflected into the vertical end of the T-shaped opening 205, when the pressing plate 206 needs to be reset, pull the sliding block 210 away from the limiting block 209, then the pressing plate 206 can be deflected horizontally.

[0034] Further, the edge of the top of the mold 202 is provided with an inverted bevel, the side wall of the mold 202 is provided with a square groove 211, the top of the fixed plate 201 is provided with a limiting groove 212, the inner part of the limiting groove 212 is slidably provided with a rectangular frame 213 and a pull plate 214 respectively, the rectangular frame 213 and the pull plate 214 are fixedly connected, and the size of the rectangular frame 213 is matched with the mold 202.

[0035] When the pulp product is in close contact with the size of the mold 202, the square groove 211 is located on the transverse cutting line of the pulp product, so that the edge of the cutting piece 106 can move into the square groove 211 during cutting, so that the pulp product can be completely divided into two, and the local area can be completely cut. The rectangular frame 213 is completely located in the limiting groove 212, and the rectangular frame 213 is located at the bottom of the pulp product. After the pulp product is cut, a square frame-shaped pulp product is left on the mold 202. By lifting the pull plate 214, the rectangular frame 213 can be slid upward along the outer wall of the mold 202, and the square frame-shaped pulp product can be quickly taken out of the mold 202 by using the rectangular frame 213. After taking out, the rectangular frame 213 is lowered into the limiting groove 212.

[0036] Further, the bottom of the limiting groove 212 is fixedly connected with a T-shaped plate 215 penetrating the pull plate 214, and the top end of the T-shaped plate 215 is higher than the top of the mold 202.

[0037] The height of the rectangular frame 213 is limited by the T-shaped plate 215. When the rectangular frame 213 rises to the top of the mold 202, the cut pulp product can be quickly removed, and then the rectangular frame 213 can be quickly lowered into the limiting groove 212 by using the T-shaped plate 215 to complete the reset.

[0038] During use, the air bag 207 is compressed by pressing the pressing plate 206, and then the extension end of the pressing plate 206 is deflected into the horizontal end of the T-shaped port 205. Then push the sliding block 210, and the limiting block 209 limits the sliding block 210. At this time, the pressing plate 206 cannot be deflected horizontally. Then, the square box pulp product is inverted on the mold 202, then pull the sliding block 210 away from the limiting block 209, then deflect the extension end of the pressing plate 206 into the vertical end of the T-shaped port 205. At this time, the air bag 207 is pushed upward by natural elasticity to push the pressing plate 206 upward, and a certain negative pressure is formed inside the air bag 207 and the gas pipe 203, so that the pulp product is adsorbed on the mold 202. Then, the cross-shaped electric sliding rail 104 is lowered by the electric telescopic cylinder 103, which can drive the servo motor 105 to move, and the servo motor 105 drives the cutting piece 106 to cut the four sides of the pulp product, and the square groove 211 cuts the pulp product at the waist;

[0039] After cutting, the electric telescopic cylinder 103 drives the cross electric sliding rail 104 to rise, then the pressing plate 206 is pressed to the limit, the remaining air in the air bag 207 is discharged through the air pipe 203, so that the air pipe 203 no longer adsorbs the paper pulp product and blows it upward, so that the worker takes out the cut paper pulp product from the mold 202, then the rectangular frame 213 is lifted to take out the paper pulp product left on the mold 202, and then the rectangular frame 213 is lowered to the limiting groove 212.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
