Description

Technical Field

[0001] The invention belongs to the technical field of plate hot pressing equipment, and particularly relates to a plate discharging device of a hot press. Background Art

[0002] The production of double veneer panels mainly uses a hot press to tightly bond the decorative paper to the upper and lower surfaces of the board through hot pressing. Figure 2 As shown, with the advancement of technology, the company has set up a feeding conveying mechanism 300 located at the inlet end of the hot press 200 and a discharging conveying mechanism 100 located at the outlet end of the hot press 200 during the production process, replacing the previous manual planking method and greatly improving efficiency.

[0003] For example, the utility model patent application number 201620949877.X discloses a novel feeding and discharging conveyor mechanism for double-decorated panels, which uses suction cups to directly grasp the double-decorated panels. However, in actual use, it was found that due to the operating pressure of the hot press machine ranging from 400 to 600 kgf, the bottom surface of the hot-pressed double-decorated panels and the hot-pressing table are tightly adhered due to the strong force. As a result, the bottom surface of the double-decorated panels is damaged when directly grasped, and some decorative paper remains adhered to the hot-pressing table, resulting in a decrease in the yield rate and increased operating costs for enterprises.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the Invention

[0027] The present invention provides a sheet material discharge device for a hot press. To clarify the objectives, technical solutions, and effects of the present invention, the present invention is further described below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended only to illustrate the present invention and are not intended to limit it. It should be noted that, in the present invention, orientation is defined as follows: the discharge direction of the hot press is defined as the front-to-back direction.

[0028] See also Figure 1 、 Figure 2、 Figure 3 、 Figure 4 The present invention provides a sheet material discharge device 1 for a hot press, comprising a running frame 11 disposed at the outlet of the hot press 200 and movable back and forth in the discharge direction, and a plate suction frame 12 disposed on the running frame 11 and capable of being raised and lowered. The bottom surface of the plate suction frame 12 is provided with at least two rows of flat vacuum cups 14 and at least two rows of corrugated vacuum cups 15 for sucking sheet materials, respectively. The corrugated vacuum cups 15 are disposed on the outside of each row of the flat vacuum cups 14.

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 As shown, the running frame 11 is provided with a slider 114, and correspondingly, the discharge conveying mechanism 100 is provided with a slide rail 4 that is slidably connected to the slider 114. The slider 114 effectively supports the plate discharge device 1 and facilitates the plate discharge device 1 to move back and forth along the slide rail 4. In addition, the discharge conveying mechanism 100 is provided with a synchronous belt mechanism 3, and the running frame 11 is correspondingly provided with a connecting portion 113 that is fixedly connected to the synchronous belt of the synchronous belt mechanism 3. With the help of the operation of the synchronous belt mechanism 3, the running frame 11 is prompted to move back and forth along the synchronous belt, and the double veneer panel is removed from the hot press 200 and placed on the belt conveyor 2 in the discharge conveying mechanism 100, so as to facilitate the conveyance of the double veneer panel to the next process.

[0030] In the present invention, a flat vacuum suction cup 14 is provided on the suction plate frame 12, and a corrugated vacuum suction cup 15 is also provided on the outside of the flat vacuum suction cup 14. When the suction plate frame 12 moves with the running frame 11 to above the hot pressing table of the hot press 100, the suction plate frame 12 descends, and uses the flat vacuum suction cup 14 to vacuum adsorb the middle position of the double decorative panel, and uses the corrugated vacuum suction cup 15 to vacuum adsorb the two ends of the double decorative panel.

[0031] When vacuuming the double-sided veneer, the corrugated vacuum suction cups 15, due to their corrugated structure, cause the ends of the double-sided veneer to be higher than the middle (i.e., the ends of the double-sided veneer are slightly tilted), presenting a certain curvature, thereby allowing the bottom surfaces of the double-sided veneer to be separated from the hot pressing table first. At this time, air is filled between the bottom surface of the double-sided veneer (i.e., the decorative paper) and the hot pressing table. Therefore, when the suction plate frame 12 is lifted, the flat vacuum suction cups 14 and the corrugated vacuum suction cups 15 rise together with the adsorbed double-sided veneer. The center of the double-sided veneer is effectively separated from the hot pressing table by the suction effect of the flat vacuum suction cups 14 and the air pressure between the decorative paper and the hot pressing table, thus ensuring that the bottom surface of the double-sided veneer is intact and greatly improving the yield rate.

[0032] In the past, the entire double-decorated panel was lifted directly by suction cups. At this time, the lifting force of the suction cups needed to overcome the strong force exerted by the hot press table on the entire decorative paper. This undoubtedly put a lot of pressure on the device providing the lifting force. It was also easy for some decorative paper to separate from the panel during the adsorption and lifting process and stick to the hot press table, thereby increasing the scrap rate.

[0033] However, the plate discharging device designed in the present invention first overcomes the force exerted by the hot pressing table on the two ends of the decorative paper located on the bottom surface of the double veneer panel through the adsorption effect of the corrugated vacuum suction cup, thereby separating the decorative paper at these locations from the hot pressing table; then, during lifting, the adsorption effect of the flat vacuum suction cup and the atmospheric pressure overcome the force exerted by the hot pressing table on the middle position of the decorative paper located on the bottom surface of the double veneer panel. At this moment, not too much pressure is exerted on the device providing the lifting force, and finally the entire double veneer panel is well separated from the hot pressing table, ensuring that the double veneer panel is intact, and the service life of the device providing the lifting force can be extended.

[0034] like Figure 1 、 Figure 4 As shown, in this embodiment, three flat vacuum cups 14 are provided in each row, and two corrugated vacuum cups 15 are provided in each row and are respectively located on the left and right sides of each row of flat vacuum cups 14 .

[0035] Of course, depending on actual needs, the number of flat vacuum cups 14 in each row can be set to multiple, and one or two corrugated vacuum cups 15 are respectively provided on the left and right sides of each row of flat vacuum cups 14. In addition, the corrugated vacuum cups 15 can be provided in front of the first row of flat vacuum cups 14 and behind the last row of flat vacuum cups 14, so that the corrugated vacuum cups can vacuum the ends of the double-sided veneer.

[0036] like Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, specifically, the suction plate frame 12 is provided with at least two support shafts 121 fixed to the left and right sides of the suction plate frame 12, respectively, and a first roller 123 and a second roller 122 rotatably mounted on the support shafts 121. The running frame 11 is provided with a support rod 111 for supporting the support shaft 121. An inclined iron 16 that can move forward and backward is provided inside the support rod 111 along its length corresponding to the support shaft 121. The inclined surface of the inclined iron 16 is provided with a roller groove 161 suitable for rolling connection with the first roller 123. The support rod 111 is provided with a vertically fixed limit rod 18, which is rollingly connected to the second roller 122 to drive the support shaft 121 to move only vertically.

[0037] The support shaft 121 can be fixed on the suction plate frame 12 by welding. The limiting rod 18 can be fixed on the support rod 111 by screw connection or welding. The support rod 111 is correspondingly provided with an opening suitable for inserting the first roller 123.

[0038] A first roller 123 and a second roller 122 are respectively mounted on the support shaft 121. When the inclined iron 16 moves forward and backward, the first roller 123 rolls relative to the inclined iron 16 in the roller groove 161, adjusting the position of the first roller 123, thereby enabling the support shaft 121 to drive the suction plate frame 12 to lift. To prevent the support shaft 121 from simultaneously shifting horizontally due to the rolling action of the first roller 123 while being lifted, the interaction between the second roller 122 and the limiting rod 18 forces the support shaft 121 to move only vertically, ultimately ensuring that the suction plate frame 12 can only move back and forth in the vertical direction. This also prevents the double veneer panel from shifting horizontally when being sucked to separate it from the hot pressing table, which could tear or damage the decorative paper on the bottom surface of the double veneer panel.

[0039] like Figure 5 、 Figure 6 As shown, more specifically, the bottom of the inclined iron 16 is fixedly connected to the inclined iron connecting plate 162 located inside the support rod 111 by screw connection or welding, and the support rod 111 is fixed with at least two support rollers 17 connected to the bottom rollers of the inclined iron connecting plate 162; the support rod 111 is fixedly connected to a telescopic cylinder 13 that can drive the inclined iron connecting plate 162 to move forward and backward.

[0040] One end of the support rod 111 is provided with an opening suitable for the entry of the inclined iron 16 and the inclined iron connecting plate 162. The piston rod of the telescopic cylinder 13 is extended and retracted, which drives the inclined iron connecting plate 162 to move horizontally back and forth, thereby driving the inclined iron 16 to move horizontally and causing the first roller 123 to roll in the roller groove 161.

[0041] To reduce the operating pressure of telescopic cylinder 13 and ensure long-term stable operation, the present invention utilizes first and second rollers 123, 122, and support rollers 17, replacing sliding friction with rolling friction, significantly reducing friction. This design not only reduces friction between first roller 123 and inclined iron 16, and between second roller 122 and stop rod 18, but also allows for smooth movement of inclined iron connecting plate 16 within support rod 111, preventing sliding friction between the bottom surface of inclined iron connecting plate 16 and the bottom surface of the support rod. Ultimately, this reduces the load on telescopic cylinder 13, the device providing the lifting force.

[0042] like Figure 1 、 Figure 5 、 Figure 6As shown, more specifically, the inclined iron connecting plate 162 is fixedly connected to an L-shaped connecting piece 163 ; the telescopic cylinder 13 is fixed to the outer side of the support rod 111 and fixedly connected to the connecting piece 163 .

[0043] The support rod 111 is provided with an opening 112 corresponding to the forward and backward movement of the connecting member 163. The connecting member 163 is inserted into the opening 112 and connected to the inclined iron connecting plate 162, and is fixedly connected to the piston rod of the telescopic cylinder 13 located outside the support rod 111. Through the setting of the connecting member 163, the power connection between the inclined iron connecting plate 162 located inside the support rod 111 and the telescopic cylinder 13 located outside the support rod 111 is realized.

[0044] like Figure 1 、 Figure 4 、 Figure 5 、 Figure 7 As shown, in this embodiment, two of the support shafts 121 and the limiting rods 18 are provided. The two limiting rods 18 are provided between the two second rollers 122 and are rollingly connected to the second rollers 122 in a one-to-one correspondence.

[0045] In order to simplify the overall structure and save materials, only two limiting rods 18 can be provided. In addition, one limiting rod 18 is located on the same side of the inclined iron 16, and the other limiting rod 18 is located on the opposite side of the inclined iron 16.

[0046] When the inclined iron 16 moves backward due to the extension of the piston rod of the telescopic cylinder 13, the first roller 123 moves forward relative to the inclined iron 16 and rolls in the roller groove 161 to lift the support shaft 121. At this time, the limiting rod 18 located on the same side of the inclined iron 16 limits the second roller 122 to prevent the support shaft 121 from moving forward with the first roller 123.

[0047] When the inclined iron moves forward due to the retraction of the piston rod of the telescopic cylinder 13, the first roller 123 moves backward relative to the inclined iron 16 and rolls in the roller groove 161 to realize the lowering of the support shaft 121. At this time, the limiting rod 18 located on the opposite side of the inclined iron 16 limits the second roller 122 to prevent the support shaft 121 from moving backward with the first roller 123.

[0048] Of course, limiting rods 18 may be provided on both sides of the second roller 122 , so that the second roller 122 can be limited by the two limiting rods 18 .

[0049] like Figure 5 、 Figure 8As shown, specifically, the support roller 17 is rotatably mounted on the bottom surface of the support rod 111, and the support rod 111 is provided with a waist-shaped hole 115 suitable for the rotation of the support roller 17. The support roller 17 is mounted on the bottom surface of the support rod 111, and its upper portion is inserted into the waist-shaped hole 115 and contacts the bottom surface of the inclined iron connecting plate 162 located inside the support rod 111, providing strong support.

[0050] like Figure 5 、 Figure 6 、 Figure 8 As shown, specifically, the bottom of the support rod 111 is provided with an opening 116 for screwing the connecting piece 163 to the oblique iron connecting plate 162. After the oblique iron connecting plate 162 is placed into the support rod 111 from one end, the connecting piece 163 is inserted through the opening 112, and then screws are screwed through the opening 116 to securely connect the oblique iron connecting plate 162 and the connecting piece 163.

[0051] like Figure 7 、 Figure 8 As shown, the limiting rod 18 is fixed on the inner side of the supporting rod 111 .

[0052] like Figure 5 As shown, when viewed from the right, the projection shape of the oblique iron 16 is a right triangle.

[0053] In summary, the present invention provides a sheet material discharge device for a hot press, primarily used in the hot pressing process of double veneer panels. This device is located at the exit of the hot press and is used to remove the double veneer panels from the hot press. This device boasts a novel structure, stability, reliability, and high efficiency. Through the combined operation of flat and corrugated vacuum suction cups, the ends of the hot-pressed double veneer panels are slightly lifted. The lifting action of the suction plate frame then allows the double veneer panels to be smoothly and seamlessly separated from the hot pressing table, significantly improving the yield rate of the double veneer panels.
