[0033] Example 1
[0034] Example 1 discloses an improved continuous fully automatic plywood cold press, such as Figure 1-Figure 6 As shown, it includes a working plate 1, a lower supporting plate 101 for carrying plywood is arranged at the top axis of the working plate 1, a U-shaped supporting beam 2 is arranged above the working plate 1, a hydraulic cylinder 201 is penetrated at the inner axis of the supporting beam 2, the output end of the hydraulic cylinder 201 faces downward and is connected with a driving column 202, an upper pressing plate 3 is arranged at the bottom end of the driving column 202, a first expansion plate 301 is arranged on the left and right sides of the upper pressing plate 3, each group of the first expansion plates 301 is rotatably connected to the upper pressing plate 3 by installing hinges 302, a plurality of groups of clamping blocks 303 are symmetrically arranged on the outer walls of the front and rear ends of the upper pressing plate 3, a hemispherical fixing head 304 is arranged at the end of each group of the clamping blocks 303, a plurality of groups of springs 305 are distributed in an annular shape on the outside of the clamping blocks 303, each group of the springs 305 is elastically connected with a trapezoidal limiting block 306, The front and rear ends of the pressing plate 3 are both provided with second expansion plates 307, the interior of the second expansion plate 307 is provided with a card slot 308 adapted to the card block 303, the bottom wall of the card slot 308 is provided with a fixing slot 309 engaged with the fixing head 304, and the slot wall of the card slot 308 is provided with a limiting slot 310 matched with the limiting block 306. The upper pressing piece is designed as an expandable structure, and the left and right sides are provided with hinges to rotate the first expansion plate 301 to achieve the effect of expanding the cold pressing area, and the front and rear sides are provided with the second expansion plate 307 by means of snap-fit buckles to expand the cold pressing area of the area. The above two adjustment methods can be used to adaptively adjust large-sized and large-sized plywood, and the working area of the upper pressing piece can be arbitrarily changed by rotating the first expansion plate 301 and snap-fitting and disassembling the second expansion plate 307;
[0035] Specifically, Figure 2 - Figure 4As shown, the cold pressing area of the upper pressing plate 3 can be adjusted by rotating the first expansion plate 301 on the upper pressing plate 3, and the cold pressing area can also be adjusted by installing the second expansion plate 307 at both ends of the upper pressing plate 3. The working area can be expanded from all sides of the upper pressing plate 3. It is worth mentioning that the utility model is mainly used to adjust the cold pressing area of plywood of larger size and specification. The reduction of the plywood area can only be achieved by rotating the first expansion plate 301 to the upper pressing plate 3 or removing the second expansion plate 307 from the upper pressing plate 3, and its minimum area is the original size area of the plywood.
[0036] As a preferred solution of the utility model, in order to ensure that the first expansion plate 301 will not be separated after rotating to the plate surface of the upper pressing plate 3, it is preferred that Figure 2 , Figure 3 As shown, two groups of positioning posts 311 are symmetrically arranged on the surface of the first expansion plate 301, and a positioning hole 312 adapted to the positioning post 311 is opened on the top of the upper pressure plate 3. When the first expansion plate 301 is rotated to the surface of the upper pressure plate 3, the positioning post 311 is inserted into the positioning hole 312 to achieve locking positioning between the two, thereby preventing the first expansion plate 301 from being detached from the upper pressure plate 3 due to external force.
[0037] like Figure 5 As shown, in this embodiment, a first limit plate 203 is provided at the bottom end of the support beam 2, and a second limit plate 204 matched with the first limit plate 203 is provided on the outer wall of the driving column 202.

The reinforcing ribs 205 can provide stable supporting stress for the support beam 2 when it is working, thereby improving the supporting stability. The assembly plate 206 and the assembly bolts 207 facilitate the installation of the corresponding working position of the support beam 2.
[0039] As a preferred solution of the utility model, in order to collect the excess glue during the cold pressing process, it is preferred that Figure 2As shown, the outer periphery of the lower support plate 101 located on the working plate 1 is sequentially provided with a first groove 102 and a second groove 103 from the inside to the outside, the groove depth of the first groove 102 is greater than that of the second groove 103, and the bottom ends of the first groove 102 and the second groove 103 are both provided with a guide plate 105 surrounding the groove wall, and the groove walls of the first groove 102 and the second groove 103 corresponding to the position of the guide plate 105 are both provided with guide holes 104, and the glue slides along the side wall of the lower drag plate to the board surface of the guide plate 105 in the first groove 102. Since the guide plate 105 is arranged in an inclined shape, the glue passes through the first groove 102 and the second groove 103 and flows out along the board surface of the guide plate 105 and each group of guide holes 104.
[0040] Specifically, Figure 5 As shown, a workbench 106 is arranged around the top of the work plate 1, and a collecting hole 107 is arranged at the bottom of the workbench 106 and corresponds to the guide plate 105. The glue flowing out of the guide hole 104 flows out along the collecting hole 107 of the workbench 106 to collect the excess glue of the cold pressing.
[0041] Example 2
[0042] like Figure 7 As shown, the present embodiment provides a mobile self-rescue crane for grain depot outbound operations, and its structure is basically the same as that of Embodiment 1, except that four groups of motors 108 are arranged on the circumference of the table top of the workbench 106, and the output end of each group of motors 108 is rotatably connected to a threaded rod 109, and a threaded block 110 is threadedly connected to the threaded rod 109. An electric push rod 111 is arranged on the side wall of the threaded block 110, and a scraper 112 is connected to the output end of the electric push rod 111. The threaded rod 109 is driven to rotate by each group of motors 108, so that the threaded block 110 moves back and forth on the threaded rod 109, thereby driving the scraper 112 to move back and forth on the plywood surface to scrape off the glue, and the electric push rod 111 pushes the scraper 112 to move, thereby changing the working range of the scraper 112, and each side of the plywood corresponds to a group of motors 108 and scrapers 112, so that the glue on each side of the plywood can be scraped off.
[0043] Working principle:
[0044] Refer to the accompanying drawings of this application specification Figure 1-Figure 6, the support beam is installed by driving the assembly bolts into the assembly plate, and then the plywood to be processed is placed on the lower support plate and coated with glue. According to the size of the processed plywood, the first expansion plate is rotated by installing the hinge, and the second expansion plate is installed in a docking manner so that the total size of the upper pressure plate after expansion just covers the working area of the plywood. Then the hydraulic cylinder is turned on, and the hydraulic cylinder controls the driving column to drive the upper pressure plate to move downward so that it contacts the surface of the plywood. The upper pressure plate and the lower support plate extrude the plywood, and the squeezed glue falls into the first groove and flows out from the guide hole along the guide plate, and finally flows out of the collecting hole of the workbench for collection, and the motor is turned on, so that the scraper can move back and forth on the surface of the plywood to scrape and clean the glue on the surface of the board. The scraper can be moved to the area by the electric push rod according to the position where the glue is attached for scraping. When controlling the movement of the driving column, the hydraulic cylinder can limit the vertical movement mileage of the driving column through the first limit plate and the second limit plate.
[0045] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
