DETAILED DESCRIPTION

[0021] The utility model is explained by the following embodiment in combination with drawings, and the following embodiment is not limited to the following embodiment of the utility model.

[0022] ReferenceFigures 1-2 The embodiment relates to an adjustable composite paperboard press, which comprises a frame 100, a workbench 1 arranged on the frame 100, and a press body formed by a pressure plate 3 driven to slide up and down by a pneumatic element 2 arranged on the top of the frame 100. Two groups of fixing bases 101 are arranged on the frame 100 on the two sides of the workbench 1. A connecting base 4 is arranged to slide on the fixing base 101, and a locking piece 1011 is arranged to rotate on the fixing base 101 corresponding to the sliding connection. Two groups of the connecting bases 4 are provided with light curtains 5 that are opposite to each other.

[0023] Specifically, in the embodiment, as shown in the whole structure of the press body, Figure 1 when in use, the paperboard can be placed on the workbench 1, and the Figure 2As shown, the pressing plate 3 can be driven by the pneumatic element 2 to reciprocate the paperboard placed above the workbench 1, and the pneumatic element 2 can be adapted according to the requirements of the use to select the corresponding type and stroke of the cylinder. During the pressing process, the light curtain 5 placed on both sides of the workbench 1 and opposite to each other can be adjusted in height by sliding up and down on the fixed seat 101, and the locking piece 1011 arranged on the corresponding position of the fixed seat 101 can be used to lock the connecting seat 4 in the corresponding height. Thus, the height of the light curtain 5 on the connecting seat 4 can be adjusted according to the thickness and standard of the paperboard after pressing. The light curtain 5 can detect the height of the upper end surface of the paperboard on the workbench 1 in real time during the repeated pressing process of the pressing plate 3. When the pressing plate 3 finishes pressing the paperboard on the workbench 1, the light curtain 5 starts to work by lifting up and leaving the paperboard. The light curtain 5 can be connected with the pneumatic element 2 through the controller to transmit signals, so that the detection result of the light curtain 5 can be combined, that is, when the thickness of the paperboard does not meet the standard and blocks the irradiation range of the light curtain 5, the pneumatic element 2 can drive the pressing plate 3 to continue the pressing process until the upper end surface of the paperboard is below the irradiation surface of the light curtain 5, so that the entire pressing process of the paperboard is completed. Compared with the conventional press structure, the light curtain 5 arranged on both sides of the workbench 1 of the press body can detect the thickness of the paperboard in real time during the pressing process, and the repeated pressing process of the pressing plate 3 driven by the pneumatic element 2 can ensure the uniformity, stability and uniformity of the pressure during the batch pressing process of the paperboard, further improve the pressing effect and stability of the press, facilitate the subsequent printing or cutting of the paperboard, and display the working state of the press body in real time through the control panel 110 arranged on the corresponding position of the rack 100. At the same time, the multiple adjustment knobs 120 and adjustment keys arranged on one side of the control panel 110 on the rack 100 can be used to monitor and adjust the corresponding parameters. In addition, the light curtain 5 can be set for a certain time delay during the detection process, and the adjustment knobs 120 and adjustment keys arranged on one side of the control panel 110 on the rack 100 can be used to control and adjust the detection parameters of the light curtain 5, which can effectively reduce the influence of the rebound phenomenon of the paperboard on the accuracy of the detection result during the pressing process, further improve the detection effect of the light curtain 5 and the pressing stability of the press body.

[0024] The pressure plate 3 is slidably mounted above the worktable 1 via multiple sets of connecting rods 102 located at the corners of the frame 100 and multiple sets of matching sliders 31 installed at their sliding positions. The pressure plate 3 can move up and down above the worktable 1 via the sliders 31 at corresponding positions along multiple sets of connecting parts located at corresponding positions on the frame 100. The arrangement of the multiple sets of connecting rods 102 on the frame 100 and the corresponding sliding method of the pressure plate 3 can further improve the stability of the pressure plate 3 during the sliding process, effectively reducing the phenomenon of large swaying or even positional deviation of the pressure plate 3 during the repressing process, which leads to instability in the repressing of the cardboard. It can further improve the pressure stability and uniformity of the pressure plate 3 on the cardboard on the worktable 1 during the pressing process, and can further expand the pressing range of the pressure plate 3, improving its applicability and practicality.

[0025] The connecting seat 4 is slidably mounted on the fixed seat 101 via multiple sets of second connecting rods 102 located at its bottom. Each second connecting rod 102 is also marked with graduation lines 411. Figure 2 or Figure 3 As can be seen, when the connecting seat 4 slides up and down on the fixed seat 101 via the multiple sets of second connecting rods 102 at the bottom, the real-time height of the connecting seat 4 can also be observed and judged via the scale lines 411 marked on the second connecting rods 102. This ensures the uniformity of the height of the two sets of connecting seats 4 on both sides of the workbench 1 and the position accuracy and detection stability of the two sets of light curtains 5 on them, further improving the convenience, accuracy and efficiency of adjusting the connecting seat 4 and the light curtains 5 on it.

[0026] The workbench 1 is also provided with a plurality of groups of through grooves 11 and a plurality of groups of second light curtains 6 installed on the bottom of the workbench 1. The plurality of groups of second light curtains 6 arranged around the corresponding position on the bottom of the workbench 1 can perform irradiation detection on the workbench 1 within a certain area through the through grooves 11, so as to limit the position of the paperboard placed on the workbench 1 according to the size of the paperboard, ensure that the paperboard is within the detection area formed by the second light curtain 6, and facilitate the operator to correct and adjust the position deviation of the paperboard on the workbench 1 during the repeated pressing process of the pressing plate 3, thereby further improving the pressing effect and pressing stability of the press body. In addition, the second light curtain 6 can also have a certain safety protection effect. When the operator's hands are on the workbench 1 during operation and block the irradiation surface of the second light curtain 6, the controller can control the pneumatic element 2 to stop, thereby improving the safety of the operator during the operation of the press. In addition, the adjustment knob 120 and the adjustment button arranged on one side of the control panel 110 below the rack 100 can be selectively opened and closed, and the corresponding parameters can be monitored and adjusted during the opening process, thereby meeting different use requirements.

[0027] The through groove 11 is provided with a plate body 12 made of transparent material. The upper end surface of the plate body 12 is flush with the upper end surface of the workbench 1. The through groove 11 can be covered with a plate body 12 made of transparent material such as glass or acrylic according to the use requirement. The setting mode that the upper end surface of the plate body 12 is flush with the upper end surface of the workbench 1 does not affect the normal detection process of the second light curtain 6 below the through groove 11, and can effectively reduce the unnecessary indentation degree on the surface of the paperboard during the pressing process, thereby reducing the adverse effect on the outer surface of the paperboard.

[0028] As shown in FIG. 1, the press body comprises a rack 100, a pressing plate 3, a workbench 1, a pneumatic element 2, a controller, a plurality of groups of through grooves 11 and a plurality of groups of second light curtains 6. Figures 3-5As shown, the workbench 1 is also provided with a plurality of through holes 13, and the plurality of through holes 13 form an exhaust passage 14 at the bottom of the workbench 1. The exhaust passage 14 is connected to the air pump 7 provided at the bottom of the rack 100 through the air pipe 15 connected at the bottom. Specifically, the plurality of through holes 13 provided on the workbench 1 and the exhaust passage 14 formed at the bottom thereof, and the air pump 7 connected to the exhaust passage 14 at the bottom through the air pipe 15 work together to enable the through holes 13 to perform the processes of inhaling and exhaling air. When the paperboard is placed on the workbench 1, the air pump 7 works to enable the through holes 13 to perform the process of inhaling air, thereby achieving a certain adsorption and fitting effect on the paperboard. During the re-pressing process, the position fixing stability of the paperboard on the workbench 1 can be effectively improved, and the phenomenon of displacement and deviation of the paperboard can be reduced. After the re-pressing is completed, the air pump 7 stops working to facilitate the taking and replacing of the paperboard. At the same time, the through holes 13 can also be used for exhaust according to the use requirements in cooperation with the air pump 7, which can achieve a certain dust removal effect and improve the functional diversity of the press body.

[0029] The filter screen 131 is provided on the through hole 13. Figure 3 As can be seen, the cover of the filter screen 131 on the through hole 13 can achieve a certain filtering effect, reduce the phenomenon of blockage of the through hole 13, and improve the working stability and efficiency of the air pump 7 through the through hole 13 and the exhaust passage 14 at the bottom thereof.
