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 , 2 As shown in Figures 4 and 5, this application discloses an explosion-proof edge cardboard cutting device, including a cardboard fixing assembly 1, a workbench 2, and a cutting machine 3. The workbench 2 is located behind the cardboard fixing assembly 1, and the cutting machine 3 is located in front of the cardboard fixing assembly 1. The cardboard fixing assembly 1 includes a first mounting frame 101. A cylinder 102 is mounted on the upper end of the first mounting frame 101. A fixing strip 104 is mounted on the output end of the cylinder 102. Limiting rods 103 are respectively mounted on both ends of the upper end of the fixing strip 104. The limiting rods 103 penetrate the upper end of the first mounting frame 101. The front end of the fixing strip 104 is provided with a rearward direction towards the bottom end. The inclined surface, the front end of the fixing strip 104 is equipped with a push plate assembly, the inner side of the first mounting frame 101 is equipped with a second mounting frame 110 near the bottom, the second mounting frame 110 is U-shaped, the front end of the second mounting frame 110 is equipped with an air jet pipe 111, the side wall of the air jet pipe 111 is equipped with several air jet nozzles 112, the inner side of the second mounting frame 110 is equipped with a square strip 116, the rear end of the square strip 116 and the rear end of the fixing strip 104 are located on the same vertical plane, the square strip 116 and the second mounting frame 110 are equipped with a flipping assembly, and the outer side of the second mounting frame 110 is equipped with a motor 122.

[0022] The cardboard is placed on the cutting machine 3, with the end of the cardboard to be cut located between the fixing strip 104 and the square strip 116. The cylinder 102 drives the fixing strip 104 to descend and fix the end of the cardboard to be cut between the square strip 116 and the fixing strip 104. The worktable 2 is started to cut the end of the cardboard to be cut. The contact groove 114 and the square strip 116 stabilize the end of the cardboard to be cut to prevent edge breakage caused by material movement or vibration during the cutting process.

[0023] like Figures 2-3 As shown, the pusher assembly includes a pusher plate 109. Several equally spaced mounting rods 108 are mounted on the upper end of the pusher plate 109. A movable block 106 is mounted on the top of the mounting rod 108. A mounting shell 105 is mounted on the outer side of the movable block 106. A spring 107 is installed between the top of the movable block 106 and the mounting shell 105. The mounting shell 105 is fixedly connected to the fixing strip 104. When the pusher plate 109 is in the initial state, it is located below the fixing strip 104. When the fixing strip 104 moves away from the cardboard under the drive of the cylinder 102, the spring 107, together with the mounting shell 105, the movable block 106, the mounting rods 108 and the pusher plate 109, limits the downward pressure of the cardboard, so that the upper end of the cardboard is separated from the bottom end of the fixing strip 104, and avoids the two from sticking together.

[0024] like Figure 4 As shown, there are two jet pipes 111. The same end of the two jet pipes 111 is connected to the air supply pipe. The air supply pipe is connected to an air pump at its inlet end. Several jet nozzles 112 are distributed horizontally at equal intervals and are positioned facing the square bar 116. The air pump sends high-pressure gas into the two jet pipes 111 through the air supply pipe. The high-pressure gas is then applied to the square bar 116 through the jet nozzles 112 to clean the paper dust on the square bar 116.

[0025] like Figures 4-5As shown, the flipping assembly includes a drive block 113 and a cylindrical block 117. The cylindrical block 117 is slidably connected to the drive block 113. The drive block 113 is movably connected to the second mounting bracket 110 via a pivot at its center. Four contact grooves 114 are provided at the contact points between the drive block 113 and the cylindrical block 117, facing upwards, downwards, front end, and rear end of the square strip 116, respectively. A groove 115 is provided on the drive block 113 between two adjacent contact grooves 114. A mounting plate 119 is installed at one end of the cylindrical block 117, and a through groove 118 is provided on the cylindrical block 117. A cylindrical pin 120 is installed at the other end of the mounting plate 119 near its edge. In the middle of groove 118, after the cardboard is removed, motor 122 drives mounting plate 119 to rotate one revolution. During this process, mounting plate 119 drives cylindrical pin 120 into groove 115 and drives drive block 113 and contact groove 114 to rotate 90 degrees. Then cylindrical pin 120 disengages from groove 115 and returns to the starting position. Cylindrical block 117 can cooperate with contact groove 114 to limit the square strip 116, which can move the clean side of square strip 116 to face upward, avoiding paper dust generated during the cutting process from being located between square strip 116 and cardboard. Due to the adhesion and small size of the powder particles, they can firmly adhere between cardboard and square strip 116, avoiding the phenomenon of cardboard sticking to square strip 116.

[0026] like Figures 1-3 As shown, there are two sets of flipping components, which are respectively installed at both ends of the square bar 116. The same connecting rod 121 is installed through the center of the two cylindrical blocks 117. The connecting rod 121 is movably connected to the second mounting bracket 110. One end of the connecting rod 121 is fixedly connected to the output end of the motor 122. By setting two sets of flipping components in conjunction with the connecting rod 121 and the motor 122, the two ends of the square bar 116 can be driven, making the flipping process of the square bar 116 smoother. Both ends of the square bar 116 can be limited by contact groove 114 in conjunction with the cylindrical block 117.

[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 edge cardboard cutting device in this application embodiment is as follows:

[0030] The cardboard to be cut is placed on the cutting machine 3, with the end of the cardboard to be cut positioned between the fixing strip 104 and the square strip 116. The machine is started, and the cylinder 102 lowers the fixing strip 104, firmly fixing the end of the cardboard to be cut between the square strip 116 and the fixing strip 104. After the cardboard is fixed, the worktable 2 is started to cut the end of the cardboard. Simultaneously, the cylindrical block 117 contacts the contact groove 114 on the drive block 113 to stabilize the square strip 116 and the end of the cardboard to be cut, preventing edge bursting during the cutting process. After cutting, the motor 122 drives the mounting plate 119 to rotate one revolution, which, through the cylindrical pin 120, enters the groove 115 and drives the drive block 113 to rotate ninety degrees, thereby causing the square strip 116 to flip over. During the flipping process, the cylindrical block 117 contacts the drive... The contact groove 114 on block 113 limits the square strip 116 to ensure stability after flipping. After flipping, the clean side of the square strip 116 faces upward, ready for the next cut. During or after flipping, the air pump starts and sends high-pressure gas into the two jet pipes 111 through the air supply pipe. The high-pressure gas is then applied to the square strip 116 through the jet nozzle 112 to clean the paper dust on the surface of the square strip 116 to be flipped, thus keeping the upper end of the square strip 116 clean. When the fixing bar 104 moves upward to release the cardboard under the drive of the cylinder 102, the spring 107 presses down the movable block 106 to drive the mounting rod 108 and the pusher plate 109 to press down the cardboard to limit it, so that the upper end of the cardboard is separated from the bottom end of the fixing bar 104, avoiding adhesion between the two and ensuring that the cardboard is taken out smoothly.

[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. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
