[0032] Two electric cylinders 601 are symmetrically distributed, the movable seat 602 is externally sleeved with the four supporting columns 4, and the outer surface of the supporting column 4 is smooth; the size of the pressing plate 605 is greater than that of the vacuum chuck 701, and the pressing plate 605 is fixedly installed at the bottom of the connecting seat 604 through a plurality of connecting ears and screws.

[0033] In the specific implementation process, during work, the paper product can be placed at the top of the stainless steel filter screen 705, and the vacuum pump 702 is started, so that the negative pressure suction force is generated in the plurality of adsorption air holes 704 inside the vacuum chuck 701, the paper product is adsorbed and fixed after passing through the stainless steel filter screen 705 through the negative pressure suction force, the stability is improved, then the two air cylinders 802 are started to be elongated, the movable seat 602 is driven to move downward, the connecting seat 604 and the pressing plate 605 are driven to move downward in cooperation with the plurality of damping rods 603 and the springs 606, until the pressing plate 605 abuts against the paper product, the paper product can be flattened, and the spring 606 is compressed and the damping rod 603 is retracted in cooperation, so that the paper product can be effectively prevented from being damaged due to excessive pressure, unnecessary loss is reduced, in the above process, since the paper product is adsorbed and fixed, the position is not easy to deviate due to mechanical vibration of the device, so that the paper product can be effectively prevented from being unevenly flattened (such as the paperboard deviating and being out of position to cause edge warping), thereby the scrap rate and the rework rate are effectively reduced, and the energy consumption and the labor cost are reduced;

[0034] The displacement sensor is arranged in the electric cylinder 601, the pressure sensor is arranged on the lower surface of the pressing plate 605, and the electric cylinder 601, the displacement sensor and the pressure sensor are all externally connected with a display control terminal, data fusion is input into a PID controller, the pressure is adjusted in real time (the precision is ±0.1kN), the display control terminal can adopt a Siemens S7-200 PLC controller, the sampling frequency is 100Hz, the pressure sensor range is 0-50kN, and an RS485 communication interface is supported;

[0035] The power of the vacuum pump 702 can be 0.75kW, and the adsorption force is greater than or equal to 5kN / m²;

[0036] The two electric cylinders 601 are symmetrically distributed, so that the movable seat 602 can be subjected to relatively uniform downward pressure, the movable seat 602 is externally sleeved with the four supporting columns 4, so that the overall stability of the movable seat 602, the connecting seat 604 and the pressing plate 605 is improved, and the outer surface of the supporting column 4 is smooth, so that the friction between the supporting column 4 and the movable seat 602 is reduced, and wear is reduced;

[0037] The pressure plate 605 is larger than the vacuum suction cup 701 to ensure that the pressure plate 605 can completely press down the paper product located on the vacuum suction cup 701. The pressure plate 605 is fixedly installed at the bottom of the connector 604 by multiple connecting ears and screws to facilitate the replacement of the pressure plate 605 (the pressure plate 605 is a consumable part).

[0038] The vacuum suction cup 701 has an internal gas collection chamber, which is connected to each adsorption hole 704. One end of the conduit 706 is connected to the suction end of the vacuum pump 702, and the other end passes through the processing table 2 and the base 3 and is sealed to the gas collection chamber. Rubber sealing rings are fitted at the through holes of the conduit 706 and the processing table 2 and the base 3. The rubber sealing rings are press-fitted with the outer wall of the conduit 706 and the inner wall of the through hole to achieve a seal.

[0039] The adsorption pores 704 are evenly distributed on the bottom surface of the groove 703, with each pore having a diameter of 2mm.

At the same time, a silicone sealing gasket is added to the edge of the groove 703 of the vacuum suction cup 701. The top of the silicone sealing gasket is flush with the top of the stainless steel filter screen 705, which enhances the sealing between the thin paper products and the vacuum suction cup 701 and improves the adsorption effect. Specific Implementation Example 2:

[0041] Reference Figure 4 and Figure 5 In a preferred embodiment, the cleaning mechanism 8 includes a fixed base 801, which is fixedly installed on the top of the processing table 2 and close to one side edge of the processing table 2. A cylinder 802 is fixedly installed through the interior of the fixed base 801. A cleaning plate 803 is fixedly connected to the telescopic end of the cylinder 802. A brush part 804 is provided at the bottom of the cleaning plate 803. The bottom height of the brush part 804 is lower than the top height of the stainless steel filter screen 705. Limiting plates 805 are also fixedly connected to the front and rear sides of the cleaning plate 803. The two limiting plates 805 are designed in an "eight" shape. The bottom height of the limiting plates 805 is higher than the top height of the stainless steel filter screen 705, and the difference between the bottom height of the limiting plates 805 and the top height of the stainless steel filter screen 705 is 2mm-3mm.

[0042] The top of the processing table 2 is fixedly connected to a limiting frame 806. The limiting frame 806 is in the shape of an inverted "U". A collection box 807 is installed inside the limiting frame 806. The collection box 807 is far away from the fixed base 801, and one side of the collection box 807 is close to the base 3. There is a gap between the top of the collection box 807 and the bottom of the vacuum suction cup 701.

[0043] In the specific implementation process, after the flattening of a single paper product is completed, the cylinder 802 can be activated to extend it and drive the cleaning plate 803 to move horizontally. When the cleaning plate 803 moves horizontally over the stainless steel filter screen 705, the brush part 804 at the bottom of the cleaning plate 803 can effectively sweep away the paper debris generated on the stainless steel filter screen 705 due to the flattening of the paper product, so as to avoid it remaining on the stainless steel filter screen 705 and affecting the flattening process of the next paper product. For example, the paper debris remaining on the stainless steel filter screen 705 will cause the bottom of the next paper product to have a pit after flattening, or the paper debris will be tightly pressed and embedded into the bottom of the paper product, reducing the product quality. At the same time, the paper debris remaining on the stainless steel filter screen 705 will also block the stainless steel filter screen 705, hindering air circulation, thereby affecting the vacuum adsorption and fixation effect on the paper product.

[0044] Among them, the two limiting plates 805 can effectively reduce paper scraps falling to the front and rear sides of the vacuum suction cup 701.

[0045] The collection box 807 is used to collect the paper scraps swept off the stainless steel filter screen 705 and vacuum suction cup 701, preventing them from scattering onto the processing table 2 and increasing the difficulty of subsequent cleaning. The limiting frame 806 is used to assist in limiting the collection box 807, preventing it from moving or shifting due to mechanical vibration and affecting its normal material collection. The gap between the top of the collection box 807 and the bottom of the vacuum suction cup 701 is to facilitate the removal of the collection box 807 and the emptying of the collected paper scraps, making it easier to complete the cleaning work.

[0046] Among them, the bristles of the 804 bristle section are made of nylon material, with a single bristle diameter of 0.15mm, a length of 15mm, and a bristle density of 50 bristles / cm².

[0047] The limiting plate 805 has an inclination angle of 15° (relative to the horizontal direction of the cleaning plate 803), which ensures that paper debris is effectively blocked from falling to the front and back sides without contacting the stainless steel filter screen 705.

[0048] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
