Description

Technical Field

[0001] The invention relates to the technical field of plywood, and in particular to a device for detecting the hardness of a stainless steel angle steel. Background Art

[0002] Plywood is a board-shaped material made by cutting wood into thin wood and then gluing it with adhesive. Plywood is one of the commonly used materials for furniture and is also widely used in the fields of construction and packaging boxes. The structure of plywood should meet two basic principles at the same time. First, the number of layers is an odd number, divided into face plate and core plate. The fiber direction of the core plate should be parallel to the face plate. At the same time, it is divided into water-resistant plywood, moisture-resistant plywood and other types according to different uses. The layers of plywood are connected by glue pressing. The plywood pressing device in the prior art can press the core plate and face plate of multiple layers, but it is usually impossible to combine the core plate, and it is impossible to achieve full-automatic processing, and the degree of automation is low.

[0048] The working principle of the multi-layer plywood pressing device disclosed in the present invention is as follows: the docking gear 110 drives the output gear 302 to rotate, thereby driving the output shaft 301 to rotate, thereby driving the output conveyor belt 303 to move, and the output rear wheel 306 drives the outer gear ring 308 to rotate, thereby driving the planetary gear 310 to rotate, thereby driving the inner gear 311 to rotate, thereby driving the input rear wheel 307 to rotate, and driving the input conveyor belt 305 to move. The output rear wheel 306 and the input rear wheel 307 rotate in opposite directions. The mold 130 of the panel 312 is placed on the input conveyor belt 305, and the input conveyor belt 305 transports the mold 130 toward the input rear wheel 307, and the camphor wood board 139 is put into the upper conveyor belt 114 from the upper board inlet 115, and the poplar wood board 140 is put into the lower conveyor belt 117 from the lower board inlet 116. The motor 105 rotates to drive the motor wheel 106 to rotate, and the driving wheel 108 is driven to rotate through the oblique transmission belt 107, thereby driving the intermediate wheel 109 and the docking gear 110 to rotate, and the intermediate The wheel 109 drives the upper transmission wheel 111 and the upper driving wheel 112 to rotate through the vertical transmission belt 113, thereby realizing the synchronous movement of the lower conveyor belt 117 and the upper conveyor belt 114 to transport the camphor board 139 and the poplar board 140. The upper conveyor belt 114 will drive the upper driven wheel 119 to rotate, and drive the lower pressure plate 122 and the blocking plate 121 to descend through the eccentric column 120, and the blocking spring 123 is compressed. When the eccentric column 120 passes through the lower pressure plate 122, the blocking spring 123 rebounds, causing the blocking plate 121 to rise. Thus, intermittent feeding of the camphor wood board 139 and the poplar wood board 140 is achieved through the blocking plate 121. The camphor wood board 139 and the poplar wood board 140 will reach the front of the cutting knife 125, and the poplar wood board 140 at the rear will push the poplar wood board 140 and the camphor wood board 139 in the front forward and reach the support plate 138. When the camphor wood board 139 or the poplar wood board 140 contacts the push rod 127 and continues to move forward, it will push the push rod 127, and the push rod spring 128 will be compressed. When the push rod 127 contacts the switch 126, the motor 105 stops rotating. When the switch 126 is pressed, the cutting electric cylinder 124 starts, driving the cutting knife 125 to descend, and the camphor wood board 139 or poplar wood board 140 located outside the mold 130 is cut off by the cutting knife 125. At the same time, the lifting electric cylinder 132 extends, driving the lifting plate 133 to rise, thereby driving the lifting block 134 to rise, driving the rotating plate 135 to rotate, thereby driving the slider 136, the outer pull block 137 and the support plate 138 to slide outward, and the camphor wood board 139 and the poplar wood board 140 located on the support plate 138 fall into the mold 130. When the lifting plate 133 continues to rise, it will contact the lifting frame 202 and drive the lifting frame 202 to rise.When the switch 126 is pressed, the glue pressing electric cylinder 102 extends to drive the glue pressing frame 103 and the glue pressing plate 104 to descend. At this time, the mold 130 on the output conveyor belt 303 and the input conveyor belt 305 just reaches under the glue pressing plate 104, and the glue pressing plate 104 is used to press glue on the surface of the panel 312 in the mold 130 on the input conveyor belt 305. At the same time, the glue pressing plate 104 is used to press glue on the poplar board 140 and the camphor board 139 in the mold 130 on the output conveyor belt 303. When the descending frame 129 descends, the upper rack 215 is driven to descend at the same time, thereby driving the transfer gear 213 to rotate, thereby driving the lower rack 212 and the lifting frame 202 to rise, so that the toggle wheel 209 passes through the long groove at the bottom of the descending frame 129 and contacts the mold 130. At the same time, the toggle wheel 209 contacts the mold 130 on the input conveyor belt 305, and the conveying motor 203 rotates to drive the motor gear 204 to rotate, and drives the intermediate gear 205 to rotate through the horizontal transmission belt 211, thereby driving the gear shaft 206 and the driving gear 207. The transmission gear 208, the toggle gear 210 and the toggle wheel 209 rotate, thereby driving all the toggle wheels 209 to rotate simultaneously. The toggle wheel 209 transports the mold 130 originally located on the descending frame 129 to the output conveyor belt 303, and transports the mold 130 originally located on the input conveyor belt 305 to the descending frame 129. Then the push rod 127 is reset under the rebound of the push rod spring 128, the cutting cylinder 124, the lifting cylinder 132 and the glue pressure cylinder 102 are reset, and the motor 105 starts to continue to rotate. The output conveyor belt 303 transports the mold 130 equipped with the panel 312, the poplar board 140 and the camphor board 139 toward the direction of the output shaft 301. Finally, the upper panel 312 is manually placed on the poplar board 140 and the camphor board 139 in the mold 130, and then the mold 130 is taken away for drying.
