The two sides of the gear 210 are meshed in the tooth grooves of the rack 212. The square grooves 211 are mirrored on both sides of the ladder groove 203. The outer wall of the rack 212 is slidably connected inside the square groove 211. The two sides of the rack 212 are respectively meshed with the gear 210 and the transmission member 213.

[0040] Through the arrangement, the operator manually places the cardboard to be folded on the surface of the fixed plate 201. After placing it, the operator manually slides the push block 215 upward from the concave groove 214 and takes it out. According to the length of the cardboard, the extension length of the push block 215 on the surface of the fixed plate 201 is adjusted. When the cardboard is shorter, the push block 215 is close to the sliding column 204. When the cardboard is longer, the push block 215 is away from the sliding column 204. After adjustment, the push block 215 is clamped in the concave groove 214, and the transmission member 213 is clamped inside the tooth groove 217.

[0041] After adjusting the push block 215, the operator puts his hand on the cardboard on the surface of the sliding column 204 to press the cardboard. At this time, the sliding column 204 begins to slide downward inside the ladder groove 203.

[0042] Reference Figure 1 , 4 , 5, 6, the adsorption mechanism 3 includes a vacuum chamber 301 fixedly arranged inside the support platform 101, two ends of one side of the sliding block 1 302 movably penetrate the side of the support platform 101 and are slidably connected to one side of the inner wall surface of the vacuum chamber 301, two ends of one side of the sliding block 2 303 movably penetrate the other side of the support platform 101 and are slidably connected to the other side of the inner wall surface of the vacuum chamber 301, the offset hole 304 is penetrated and opened on one side of the surface of the sliding block 1 302 and the sliding block 2 303, and the round through hole 2 305 is penetrated and opened on the surface of the sliding block 1 302 and the sliding block 2 On the other side of the surface of the sliding block 2 303, the shell of the vacuum pump 306 is fixedly installed on one side of the surface of the base 1, and the output end and the input end of the vacuum pump 306 are fixedly connected to the outer wall of one side of the support platform 101, and the output hole of the output end and the input hole of the input end of the vacuum pump 306 are interconnected with the inside of the vacuum chamber 301. The active chamber 2 307 is non-through-opened at both ends of one side of the sliding block 2 303, one end of the connecting block 308 is fixedly connected to one side of the sliding block 1 302, and the outer wall of the connecting block 308 is slidably connected and clamped inside the active chamber 2 307.

[0043] Among them, the vacuum pump 306 is an existing device, and the shell of the vacuum pump 306 is fixedly installed on one side of the surface of the base 1. The output end and the input end of the vacuum pump 306 are fixedly connected to the outer wall of one side of the support platform 101. The output hole of the output end and the input hole of the input end of the vacuum pump 306 are interconnected with the inside of the vacuum chamber 301. The vacuum pump 306 is composed of parts such as a rotor and a stator, blades and vanes, bearings, couplings and motors. Because the vacuum pump 306 is an existing device, it will not be described in detail here. The holes opened on the outer wall of the support platform 101 are coated with sealant. After the sealant dries, it can form a sealing layer to effectively prevent the penetration of gas and moisture.

[0044] By setting, the operator adjusts the sliding block 1 302 and the sliding block 2 303 according to the length of the cardboard. When the cardboard is long, there is no need to pull the sliding block 1 302 and the sliding block 2 303. The round through hole 2 305 in the initial state is interconnected with the round through hole 1 202 on both sides of the fixed plate 201, and the offset hole 304 is offset with the round through hole 1 202 in the middle of the fixed plate 201. At this time, the longer cardboard can be adapted. When the cardboard is short, the sliding block 1 302 and the sliding block 2 303 are pulled outward until the sliding block 1 302 and the sliding block 2 303 cannot be pulled outward. At this time, the offset hole 304 is interconnected with the round through hole 1 202 in the middle, and the round through hole 2 305 is offset with the round through hole 1 202 on both sides of the fixed plate 201. At this time, the shorter cardboard can be adapted.

[0045] After adjusting the sliding block 1 302 and the sliding block 2 303, and making the push block 215 complete the correction of the paperboard, the pressing of the paperboard is not stopped at this time, so that the paperboard and the vacuum chamber 301 form a closed space, and the vacuum pump 306 is powered on at this time.

[0046] After being started, the vacuum pump 306 begins to exhaust the air inside the vacuum chamber 301 through the output hole. When the vacuum pump 306 exhausts the air inside the vacuum chamber 301, the cardboard can be adsorbed and fixed.

[0047] After the cardboard is adsorbed and fixed, the operator slides the electric telescopic rod 103 to make the crease block 104 above the position where the folding is required, and then powers on the electric telescopic rod 103. The output end of the electric telescopic rod 103 pushes the crease block 104 to crease the cardboard.

[0048] The implementation principle of a cardboard folding device in the embodiment of the present application is as follows: the operator adjusts the adsorption area of ​​the sliding block 1 302 and the sliding block 2 303 according to the length of the cardboard. After the adjustment, the pushing block 215 in the concave groove 214 is adjusted to extend the length according to the length of the cardboard. Then, the cardboard to be folded is placed on the surface of the sliding column 204, and then the cardboard is pressed downward to make the sliding column 204 slide downward inside the step groove 203. The sliding column 204 slides downward inside the step groove 203 to make the pushing block 215 calibrate the cardboard. After the calibration is completed, the sliding column 204 is continued to be pressed. At the same time, the vacuum pump 306 is powered on to start the vacuum chamber. The air inside the closed space formed between the vacuum chamber 301 and the paperboard is discharged. When the air inside the closed space formed between the vacuum chamber 301 and the paperboard is discharged, the adsorption and fixation are completed. Then, the electric telescopic rod 103 is slid to make the crease block 104 be located above the position where the folding is required. The paperboard is indented by starting the electric telescopic rod 103. After the indentation is completed, the vacuum pump 306 is started to inject air into the closed space formed between the vacuum chamber 301 and the paperboard. Through the injection of air, the adsorption of the paperboard is stopped, and the push block 215 also stops correcting and fixing the paperboard. The sliding column 204 lifts the paperboard on the surface of the fixing plate 201, and the indentation and folding of the paperboard are completed.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
