Description

Technical Field

[0001] The present invention relates to the technical field of plywood hot pressing machinery, and specifically relates to an intelligent high-rise multi-board automatic hot press for simultaneously hot pressing multiple boards to be glued. Background Art

[0002] As is well known, during the processing of wood composite boards, an adhesive needs to be filled between each layer of boards and then a pressing process is carried out. In the existing process, a simple auxiliary cold pressing die is usually used to perform a single pressing process on woodworking composite boards. The auxiliary cold pressing die is composed of a lower pressing plate, an upper pressing plate, and a clamping device. During pressing, an operator places the veneer plywood to be pressed on the lower pressing plate, then covers the upper pressing plate, and the clamping device clamps around the lower pressing plate and the upper pressing plate for cold pressing at normal temperature. The substantial deficiency of this structure is that the operator can only press one plywood board each time, which is not only time-consuming and laborious, with extremely low production efficiency, but also the pressing thickness is uneven, and there are even air bubbles in some of the pressed plywood boards, resulting in poor pressing quality. Summary of the Invention

[0003] In order to solve the above-mentioned substantial deficiencies of the prior art, the present invention provides an intelligent high-rise multi-board automatic hot press with novel structure, which can simultaneously hot press several plywood boards, significantly improve work efficiency, have uniform pressing thickness, high pressing quality, save time and effort, and reduce the labor intensity of workers.

[0004] The technical means adopted by the present invention to solve the above technical problems are:

[0005] An intelligent high-rise multi-board automatic hot press, characterized in that: it includes a frame (1), and an in-board storage device (60), a rotary push plate robot (61), a hot pressing device (62), an out-board storage device (63) and a control system are sequentially arranged on the frame (1) from the in-board end to the out-board end. The hot pressing device (62) includes at least one hot press platen base plate (2), a lifting hot pressing device (62)(3), a lower workbench (4), at least three unit hot press plates (5-1), (5-2), (5-3) with different lengths and equal widths, and a heating supply device (6). The rotary push plate robot (61) is controlled by the control system. The upper end surface of the hot press platen base plate (2) is a stepped support surface. The frame (1) is composed of columns (1-1), an upper beam (1-2), and a lower beam (1-3). The upper beam (1-2) is located above the lower beam (1-3). The two ends of the upper beam (1-2) and the lower beam (1-3) are respectively fixedly connected to the columns (1-1) at both ends. The lifting hot pressing device (62)(3) is fixed on the lower beam (1-3). The upper end of the lifting hot pressing device (62)(3) is fixedly connected to the lower workbench (4). A number of unit hot press plates (5-1), (5-2), (5-3) are arranged at equal intervals between the lower workbench (4) and the upper beam (1-2). The uppermost unit hot press plate (5-1) is fixedly connected to the upper beam (1-2), and the lowermost unit hot press plate 5-1 is fixedly connected to the lower workbench (4). The other unit hot press plates (5-2), (5-3) are a group that can be sequentially stacked and listed upward at intervals and are separable from the hot press platen base plate (2) and sit on different surfaces of the stepped support surface of the hot press platen base plate (2), so as to form a hot press space between adjacent unit hot press plates (5-1), (5-2), (5-3), (5-1). Two guide blocks (9) are respectively arranged at both ends of the unit hot press plates (5-2), (5-3). Heating devices are arranged in the unit hot press plates (5-1), (5-2), (5-3). The heating devices are supplied with heat by the heating supply device (6). The two guide blocks (9) are arranged in a mirror image. The heating supply device (6) is installed on the column (1-1). The heating supply device (6) and the lifting hot pressing device (62)(3) are respectively controlled by the control system. A guide rail (1-4) is fixed on the column (1-1). The guide blocks (9) are matched with the guide rail (1-4) so that the unit hot press plates can be slidably connected up and down, which is beneficial to ensuring the vertical lifting of the unit hot press plates (5-2), (5-3), and further improving the high-quality hot pressing of glued wood boards. When there are two or more hot press platen base plates (2), the adjacent hot press platen base plates are fixedly connected, and the heights of the stepped support surfaces of the hot press platen base plates increase sequentially from the inside to the outside. At the same time,The height of the highest supporting surface of the stepped supporting surface of the adjacent hot platen base plate with a lower height is equal to the height of the lowest supporting surface of the stepped supporting surface of the hot platen base plate (2) with a higher height, which is equal to the height between two adjacent supporting surfaces of the stepped supporting surface in any one of the hot platen base plates (2-1), (2-2), (2-3), (2-4), and (2-5); this serves to increase the hot pressing space. The lengths of the stepped supporting surfaces of the adjacent hot platen base plates (2-1), (2-2), (2-3), (2-4), and (2-5) in the length direction of the unit hot platen are equal, and the heights increase successively, which is conducive to increasing several hot pressing spaces and achieving the effect of simultaneously hot pressing multiple glued wood boards, significantly improving the working efficiency.

[0006] In the present invention, a plate clamping and automatic moving device (64) can be respectively provided at the plate feeding end of the plate feeding and storing device (60) and the plate discharging end of the plate discharging and storing device. The plate clamping and automatic moving device (64) is controlled by a control system, which is conducive to automatically moving several hot platens in the high-layer press into and / or out of the hot pressing space through the control system.

[0007] In the present invention, a plate feeding conveying device (65) can also be provided below the plate feeding and storing device (60). The plate feeding conveying device (65) is controlled by a control system, which is conducive to automatically controlling the plate feeding conveying device (65) to sequentially convey the plywood to be hot pressed into the plate feeding and storing device (60) through the control system.

[0008] In the present invention, a plate discharging stacking and conveying device (67) can also be provided below the plate discharging and storing device (63). The plate discharging stacking and conveying device (67) is controlled by a control system, which is conducive to automatically controlling the plate discharging stacking and conveying device (67) to sequentially clamp, stack, and output the hot pressed plywood from the hot pressing device (62) through the control system.

[0009] In the present invention, asbestos heat insulation boards (7) can be provided between the lowermost unit hot platen (5-1) and the lower workbench (4), and between the unit hot platen (5-1) and the upper beam, so as to avoid heat dissipation and further ensure that each board after simultaneous hot pressing can achieve the same hot pressing quality.

[0010] In the present invention, the heating device can adopt a maze-type steam pipeline arranged in the unit hot platen. The steam inlet and outlet of the steam pipeline are respectively arranged at one end of the unit hot platen. The steam inlet is communicated with the intake hose (6-1) of the heat supply device (6), and the steam outlet is communicated with the exhaust hose (6-2) of the heat supply device, so as to achieve the effect of uniformly bonding the adhesive in the veneer through steam heating.

[0011] In the present invention, a material supporting plate (8) may be fixedly provided at the feeding end and / or the discharging end of the unit hot pressing plate. The upper end face and / or the lower end face of the material supporting plate (8) are inclined relatively outward from the end of the unit hot pressing plate and converge at the outer end to form a guiding surface, so as to facilitate the smooth entry and exit of the plate into and out of the hot pressing space.

[0012] In the present invention, the material supporting plates (8) may be respectively arranged on both sides of the center of the unit hot pressing plate, so as to facilitate the automatic input of the plate.

[0013] In the present invention, temperature measuring sensors may be provided on the unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7), (5-1), and the temperature measuring sensors are connected to a control system, so as to achieve the function of automatically controlling the temperature.

Specific embodiments

[0057] The present invention will be described below with reference to the accompanying drawings and embodiments.

[0058] As shown in the attached Figure 1 , 2As shown in Figures 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13, an intelligent high-rise multi-plate automatic hot press is characterized in that it includes a frame (1). An in-feed and storage device (60), a rotary push plate robot (61), a hot pressing device (62), an out-feed and storage device (63), and a control system are successively arranged on the frame (1) from the in-feed end to the out-feed end. The hot pressing device (62) includes at least one hot press platen base plate (2), a lifting hot pressing device (62) (3), a lower workbench (4), at least three unit hot press plates (5-1), (5-2), (5-3) with different lengths and equal widths, and a heating device (6). The rotary push plate robot (61) is controlled by the control system,

[0059] The upper end surface of the hot press platen base plate (2) is a stepped support surface. The frame (1) is composed of columns (1-1), an upper beam (1-2), and a lower beam (1-3). The upper beam (1-2) is located above the lower beam (1-3). Both ends of the upper beam (1-2) and the lower beam (1-3) are fixedly connected to the columns (1-1) at both ends. A lifting hot press device (62)(3) is fixed on the lower beam (1-3). The upper end of the lifting hot press device (62)(3) is fixedly connected to the lower workbench (4). A number of unit hot press plates (5-1), (5-2), (5-3) are equidistantly spaced between the lower workbench (4) and the upper beam (1-2). The uppermost unit hot press plate (5-1) is fixedly connected to the upper beam (1-2), and the lowermost unit hot press plate 5-1 is fixedly connected to the lower workbench (4). The other unit hot press plates (5-2), (5-3) are a group that can be stacked upward at intervals in sequence and are separable from the hot press platen base plate (2) and sit on different surfaces of the stepped support surface of the hot press platen base plate (2), so as to form a hot press space between adjacent unit hot press plates (5-1), (5-2), (5-3), (5-1). Two guide blocks (9) are respectively provided at both ends of the unit hot press plates (5-2), (5-3). Heating devices are provided inside the unit hot press plates (5-1), (5-2), (5-3). The heating devices are heated by a heat supply device (6). The two guide blocks (9) are arranged in a mirror image. The heat supply device (6) is installed on the column (1-1). The heat supply device (6) and the lifting hot press device (62)(3) are respectively controlled by a control system. The control system is a PLC control system. A guide rail (1-4) is fixed on the column (1-1). The guide block (9) is matched with the guide rail (1-4) so that the unit hot press plate can be slidably connected up and down, which is beneficial to ensuring the vertical lifting of the unit hot press plates (5-2), (5-3), and further improving the high-quality hot pressing of glued wood sheets. When there are two or more hot press platen base plates (2), adjacent hot press platen base plates are fixedly connected, and the height of the stepped support surface of the hot press platen base plate increases sequentially from the inside to the outside. At the same time, the height of the highest support surface of the stepped support surface of the adjacent hot press platen base plate with a lower height is equal to the height between two adjacent support surfaces of the stepped support surface of any one of the hot press platen base plates (2-1), (2-2), (2-3), (2-4), (2-5); to achieve the effect of increasing the hot press space. The lengths of the stepped support surfaces of the adjacent hot press platen base plates (2-1), (2-2), (2-3), (2-4), (2-5) in the length direction of the unit hot press plate are equal, and the heights increase sequentially, which is beneficial to increasing a number of hot press spaces and achieving the effect of simultaneously hot pressing multiple glued wood sheets, significantly improving the working efficiency.

[0060] As shown in the appendix Figure 13 , 14, as shown in Fig. 15, the rotary push plate robot (61) of the present invention includes a manipulator (10), a manipulator fixed shaft (11), a manipulator lifting device 12, a manipulator rotation driving device 13 and a control system. The manipulator (10) is located at the front of the unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) arranged between two columns (1-1). The manipulators (10) are arranged at intervals from top to bottom and are arranged in two columns mirror-symmetrically on both sides of the center of the unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7). The distance between adjacent manipulators (10) is the same as the distance between adjacent unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7). One end of the manipulator (10) is fixedly connected to the manipulator fixed shaft (11), and the other end is a free end that can swing into the hot pressing space. The manipulator fixed shaft (11) is located in front of the feeding end of the column. One side of the manipulator fixed shaft (11) is rotatably connected to the manipulator lifting device 12 through an upper connecting arm (12-6) and a lower connecting arm (12-7) respectively. The manipulator lifting device is slidably and rotatably connected to the column, so as to drive the manipulator (10) to rise or fall through the manipulator lifting device 12. When rising, the hot-pressed plywood can be automatically pushed out of the hot pressing space by inserting the manipulator (10) into the hot pressing space. When descending, the manipulator (10) and the unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) are at the same horizontal position, avoiding the manipulator (10) blocking the plywood to be hot-pressed from entering the hot pressing space. The upper ends or lower ends of the two manipulator fixed shafts (11) are respectively driven to rotate by the manipulator rotation driving device 13. The manipulator rotation driving device 13 is in rolling connection with the longitudinal slide rail provided on the upper beam (1-2). The manipulator lifting device 12 and the manipulator rotation driving device 13 are respectively connected to the control system. By driving the manipulator fixed shaft (11) to rotate through the manipulator rotation driving device 13, the manipulator (10) on the manipulator fixed shaft (11) can swing to synchronously push out the plywood, achieving the effects of novel structure, high automation degree and high working efficiency.

[0061] As shown in the appendix Figure 15As shown in the figure, the manipulator lifting device 12 of the present invention includes a lifting oil cylinder (12-1), a lifting shaft (12-2), a rotating joint (12-3), an upper guide sleeve (12-4), a lower guide sleeve (12-5), an upper connecting arm (12-6), and a lower connecting arm (12-7). The upper guide sleeve (12-4) and the lower guide sleeve (12-5) are arranged at intervals up and down, and are respectively fixedly connected to the column (1-1) on one side. The lifting shaft (12-2) rotatably passes through the upper guide sleeve (12-4) and the lower guide sleeve (12-5). The lower end of the lifting shaft (12-2) is connected to the telescopic rod of the lifting oil cylinder (12-1) through the rotating joint (12-3). The upper connecting arm (12-6) and the lower connecting arm (12-7) are arranged at intervals on the lifting shaft (12-2). One end of the upper connecting arm (12-6) and the lower connecting arm (12-7) is rotatably sleeved on the lifting shaft (12-2), and the other end is rotatably sleeved on the manipulator fixed shaft (11). When it is necessary to push out the plywood between the unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), and (5-7), the control system commands the lifting oil cylinder (12-1) to act. The lifting oil cylinder (12-1) drives the lifting shaft (12-2) to move upward. The lifting shaft (12-2) moves upward along the upper guide sleeve (12-4) and the lower guide sleeve (12-5). At this time, the lifting shaft (12-2) drives the manipulator fixed shaft (11) to rise under the drive of the upper connecting arm (12-6) and the lower connecting arm (12-7), so that the manipulator (10) on the manipulator fixed shaft (11) moves upward to the plate feeding position in the front of the hot pressing space between the adjacent unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), and (5-7), waiting for the next plate pushing command of the control system.

[0062] As shown in the attached Figure 14 , 15As shown, the manipulator rotation drive device 13 includes a push plate oil cylinder (13-1), a connecting frame (13-2), a fixed plate (13-3), a hinge shaft (13-4), a Y-shaped joint (13-5), a guiding trolley (13-6), an upper bracket (13-7), a lower bracket (13-8), a composite bearing (13-9) and a composite bearing seat (13-10). One end of the push plate oil cylinder (13-1) is hinged to the upper beam (1-2), and the telescopic rod at the other end of the push plate oil cylinder is hinged to the center of the fixed plate (13-3) through the Y-shaped joint (13-5). The lower end of the fixed plate (13-3) is fixedly connected to the guiding trolley (13-6). Upper brackets (13-7) and lower brackets (13-8) are respectively fixed at both ends of the fixed plate (13-3). One end of the hinge shaft (13-4) is fixedly connected to the upper bracket (13-7), and the other end is fixedly connected to the lower bracket (13-8). The composite bearing (13-9) is sleeved on the hinge shaft (13-4) and can slide up and down. The composite bearing seat (13-10) is sleeved outside the composite bearing (13-9). One end of the connecting frame (13-2) is fixedly connected to the composite bearing seat (13-10), and the other end is fixedly connected to the upper end of the manipulator fixed shaft (11). The push plate oil cylinder (13-1) is controlled by a control system. When the lifting shaft (12-2) drives the manipulator fixed shaft (11) to rise, the connecting frame (13-2) fixed to the upper end of the manipulator fixed shaft (11) drives the composite bearing (13-9) to move up along the hinge shaft (13-4) through the composite bearing seat (13-10), that is, the distance between the upper bracket (13-7) and the upper end of the composite bearing (13-9) is equal to or greater than the rising stroke of the lifting oil cylinder (12-1), without affecting the horizontal push and pull of the push plate oil cylinder (13-1).

[0063] As attached Figure 14As shown in the figure, the rotary joint (12-3) of the present invention is composed of an upper connecting disc (12-3-1), a lower connecting disc (12-3-2), and a thrust ball bearing (12-3-3).

The middle of the left scissors frame (56-8-2-1) and the right scissors frame (56-8-2-2) is hinged by the scissors frame hinge shaft (56-8-2-6). The upper end of the left scissors frame (56-8-2-1) is hinged to the support platform (56-8-3), and the lower end is in rolling connection with the lower track provided on the base (56-8-1) through a lower roller.

The upper part of the left scissors frame (56-8-2-1) is provided with an upper top shaft (56-8-2-5). One end of the L-shaped top plate is sleeved on the upper top shaft (56-8-2-5), and the other end is hinged to the telescopic rod of the lifting oil cylinder (56-8-2-3). The lower end of the lifting oil cylinder (56-8-2-3) is hinged to the lower right connecting shaft of the right scissors frame (56-8-2-2). The lifting oil cylinder (56-8-2-3) is controlled by a control system.

[0094] As shown in the attached Figure 40 As shown in the figure, the plywood conveying and output device (56-8-4) of the present utility model is composed of an output driving sprocket (56-8-4-1), an output driven sprocket (56-8-4-2), a conveying chain (56-8-4-3), an output chain bracket (56-8-4-4), and a sheet output motor (56-8-4-5). Two output chain brackets (56-8-4-4) are arranged in parallel. The front ends of the two output chain brackets (56-8-4-4) are respectively connected to the output driven sprocket shaft through bearings and bearing seats, and the rear ends are respectively connected to the output driving sprocket shaft through bearings and bearing seats. The lower end of the output chain bracket (56-8-4-4) is fixedly connected to the support platform (56-8-3). Both ends of the output driven sprocket shaft are respectively connected to the output chain bracket (56-8-4-4) through bearings and bearing seats. The output driving sprocket (56-8-4-1) is connected to the output driven sprocket (56-8-4-2) through the conveying chain (56-8-4-3). The conveying chain (56-8-4-3) between the output driving sprocket (56-8-4-1) and the output driven sprocket (56-8-4-2) is supported by the output chain bracket (56-8-4-4). The output driving sprocket (56-8-4-1) is driven by the sheet output motor (56-8-4-5). The sheet output motor (56-8-4-5) is controlled by a control system.

[0095] As shown in the attachedFigure 1 As shown, the present invention may also be provided with a plywood conveying input device (66) at the feeding end of the board feeding conveying device (65). The structure of the plywood conveying input device (66) is the same as that of the plywood conveying output device, which is not described in detail, so as to facilitate the automatic input of the plywood to be hot-pressed into the board feeding conveying device (65) through the plywood conveying output device.

[0096] When the present invention is in operation, when the control system receives that the veneer plywood has arrived at the plywood conveying input device (66), the control system instructs the board output motor (56-8-4-5) in the plywood conveying input device (66) to operate, and the conveying chain (56-8-4-3) drives the veneer plywood to enter the board clamping and conveying device (49). At this time, the control system instructs the board feed rotating motor (49-3) to operate, and the board feed rotating motor (49-3) drives the board feed lower shaft (49-1) to rotate, and the board feed lower shaft (49-1) drives the board feed active roller (49-4) and the board feed driven roller (49-5) to rotate. The board-feeding conveyor belt (49-9) on the plate-feeding plate (9-5) rotates, and the plywood is transported to the gap between the board-feeding conveyor belt (49-9) and the board-feeding pressure wheel (49-8) through the transverse board-feeding device, and enters the plywood moving channel under the clamping and transportation of the board-feeding conveyor belt (49-9) and the board-feeding pressure wheel (49-8). When the front end of the plywood touches the triangular collision block (53-1) at the board-feeding end of the board-feeding plate positioning block (53), the inertial force of the plywood to be hot-pressed is gradually eliminated under the action of the upwardly inclined inclined surface of the top angle of the triangular collision block (53-1), and finally stops by colliding with the board-feeding plate positioning block (53). To avoid the plywood to be hot pressed from being dispersed due to rapid collision; then, the control system instructs the left lifting cylinder (42) and the right lifting cylinder (43) in the board feeding and board storage device (60) to operate simultaneously, driving the left unit support plate (40) and the right unit support plate (41) to rise to the height of a unit plywood moving channel and stop. At this time, the next plywood to be hot pressed is transported to the board feeding conveying device (65). Similarly, the hot pressed plywood enters the plywood moving channel under the clamping and conveying of the board feeding conveyor belt (49-9) and the board feeding pressure wheel (49-8). When the front end of the plywood touches the board feeding conveyor belt (49-9) and the board feeding pressure wheel (49-8), the plywood is transported to the board feeding conveyor belt (49-9) and the board feeding pressure wheel (49-8). The triangular collision block (53-1) at the board inlet end of the board positioning block (53) gradually eliminates the inertial force of the plywood to be hot-pressed under the action of the upwardly inclined slope of the top angle of the triangular collision block (53-1) and finally stops by colliding with the board inlet positioning block (53). The above-mentioned action is repeated repeatedly until the last plywood moving channel in the board inlet storage device (60) is transported to the last plywood moving channel in the board inlet storage device (60). The control system then instructs the board inlet rotating motor (49-3) to stop running. At this time, each veneer plywood to be hot-pressed in the board inlet storage device (60) corresponds to the hot pressing space in the hot pressing device (62);

[0097] When hot pressing plywood with different thicknesses, rotate the feed-in adjusting nut (54-4) and the feed-in locking nut (54-5), drive the feed-in lifting rod (54-3) to rise or fall, drive the feed-in pressure wheel (49-8) to rise or fall, and then adjust the gap between the feed-in pressure wheel (49-8) and the feed-in conveyor belt (49-9).

[0098] When the plywood to be hot pressed in the feed-in stock storage device (60) is to enter the hot pressing device (62), the control system commands the clamping oil cylinder (18) in the sheet clamping and automatic moving device (64) to act. The clamping oil cylinder (18) drives the unit movable splint fixing frame (23) to move downward, making the opening angle between the unit movable splint (22) and the unit fixed splint (20) the largest. When the lower positioning plate (30-5) at the lower part of the unit movable splint fixing frame (23) contacts the positioning block (30-6), since the telescopic rod of the clamping oil cylinder (18) continues to extend downward, at this time, the clamping oil cylinder (18) is driven by the telescopic rod to vertically rise in the reverse direction along the smooth rod section of the screw rod (30-1) through the guide plate (30-4), and then drives the unit movable splint fixing frame (23) and the unit movable splint (22) at the front end of the unit movable splint fixing frame (23) to move upward and clamp the veneered plywood with the unit fixed splint (20). Then, the control system commands the moving oil cylinder (16) to act. The moving oil cylinder (16) drives the moving trolley (15) to move along the longitudinal slide rail (14) towards the high-layer hot pressing device (62), and horizontally transfers several veneered plywood to be hot pressed in the feed-in stock storage device (60) to each unit hot pressing plate (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) in the hot pressing space between the unit hot pressing plates of the hot pressing device (62). When the control system receives the in-place information of the sheet clamping and automatic moving device (64) uploaded by the limit switch installed on the frame (1), the control system commands the moving oil cylinder (16) to stop moving and commands the clamping oil cylinder to return to its original position. At this time, the unit movable splint (22) moves downward relative to the unit fixed splint (20) to release the veneered plywood. At the same time, the control system commands the moving oil cylinder (16) to drive the moving trolley to return to its original position;

[0099] Since in the initial state, both columns of manipulators (10) at the feeding end of the unit hot press veneer are located in front of the unit hot press plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7), which does not affect the feeding of the plywood for hot pressing. When it is necessary to push the plywood between the unit hot press plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) to the middle position of the hot pressing space, the control system commands the lifting oil cylinder (12-1) to act. The lifting oil cylinder (12-1) drives the lifting shaft (12-2) to move upward. The lifting shaft (12-2) moves upward along the upper guide sleeve (12-4) and the lower guide sleeve (12-5). At this time, the lifting shaft (12-2) drives the manipulator fixed shaft (11) to rise under the drive of the upper connecting arm (12-6) and the lower connecting arm (12-7), so that the manipulator (10) on the manipulator fixed shaft (11) moves upward to the front of the hot pressing space between the adjacent unit hot press plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) and then stops. Then the control system commands the pushing plate oil cylinder (13-1) to act. The pushing plate oil cylinder (13-1) pushes the fixed plate (13-3). The fixed plate (13-3) drives the guiding trolley (13-6) to move along the longitudinal slide rail (14) in the plywood discharging direction. At this time, the connecting frames (13-2) at both ends of the fixed plate (13-3) rotate relatively with the hinge shaft (13-4) as the axis under the pulling of the fixed plate (13-3), and then drive the manipulator fixed shafts (11) at the other ends of the two connecting frames (13-2) to rotate relatively. The manipulators (10) fixedly spaced on the manipulator fixed shaft (11) swing under the drive of the rotation of the manipulator fixed shaft (11) and at the same time push the veneered plywood to be hot pressed between the adjacent unit hot press plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) to the middle position of the hot pressing space. Then, the control system commands the pushing plate oil cylinder (13-1) and the lifting oil cylinder (12-1) to return in sequence. The control system commands the pushing plate oil cylinder (13-1) to drive the fixed plate (13-3) to move in the reverse direction. The connecting frames (13-2) at both ends of the fixed plate (13-3) rotate away from each other with the hinge shaft (13-4) as the axis under the drive of the fixed plate (13-3). The manipulator fixed shafts (11) at the other ends of the connecting frames (13-2) rotate in the reverse direction. The manipulators (10) then return to the front of the hot pressing space between the unit hot press plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) under the drive of the rotation of the manipulator fixed shaft (11), and the pushing plate oil cylinder (13-1) stops; ready to enter the hot pressing program;

[0100] After the return, the control system immediately instructs the hydraulic control device to actuate, driving the lifting hydraulic device (3) to rise. The lifting hydraulic device (3) drives the lower workbench to rise, and the lower workbench rises and successively jacks up each unit hot pressing plate (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) to quickly move upward along the guide rails, and is successively separated from the hot pressing plate seat plates (2-1), (2-2), (2-3), (2-4), (2-5) until it is completely and quickly closed with the unit hot pressing plate (5-1) at the lower end of the upper beam and automatically pressurized. During the closing and pressurizing process, the control system instructs the heating device (6) to heat the unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) simultaneously. The present invention preferably uses steam heating, that is, steam enters each unit hot pressing plate through each intake hose (6-1), and then is discharged into the atmosphere through the steam discharge hose (6-2) and the steam trap in the heating device. At the same time, an automatic temperature measurement is also achieved by setting a temperature measuring device on the unit hot pressing plate and connecting the temperature measuring device to the control system to ensure that the temperature of each unit hot pressing plate is consistent. At the same time, it also enables the veneered plywood to pass through the pressure-holding stage and the curing stage in each hot pressing space to achieve complete compaction and gluing. At this time, the pressure, temperature, and thickness of several veneered plywood sheets hot-pressed are the same, not only avoiding the substantial technical problem of pressing bubbles between the veneered plywood sheets after pressing, but also solving the substantial technical problems of uneven thickness and low working efficiency caused by manual pressing;

[0101] After curing, the control system instructs the lifting hydraulic device (3) to descend, so that the pressure of several veneered plywood sheets after being compacted and cured drops to zero, realizing pressure relief treatment. The unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) quickly reset and open, preparing to push out the hot-pressed veneered plywood;

[0102] When storing the veneered plywood sheets, the control system first instructs the left lifting oil cylinder (42) and the right lifting oil cylinder (43) to actuate simultaneously. The left lifting oil cylinder (42) drives the left veneered plywood storage fixing frame (38) to rise. At the same time, the right lifting oil cylinder (43) drives the right veneered plywood storage fixing frame (39) to rise until it stops at the highest position where the telescopic rods of the left lifting oil cylinder (42) and the right lifting oil cylinder (43) extend. At this time, the planes of the left and right veneered plywood storage fixing frames in the veneered plywood sheet storage device (63) are lower than the height of the unit hot pressing plates in the hot pressing device (62), facilitating the smooth output of the veneered plywood;

[0103] Then, the control system instructs the moving cylinder (16) in the plate clamping automatic moving device (64) to move, and the moving cylinder (16) drives the moving trolley (15) to move along the longitudinal slide rail (14) toward the hot pressing device (62). When the unit clamping manipulator at the front end of the moving longitudinal plate frame (17) at the lower end of the moving trolley (15) approaches the plywood, the outer end of the plywood hits the support plate (24). After receiving the in-position information, the control system instructs the moving cylinder (16) to stop and instructs the clamping cylinder (18) to move. The clamping cylinder (18) drives the unit movable clamping plate fixing frame (24) to move. 3) moves downward, so that the opening angle of the unit movable splint (22) and the unit fixed splint (20) is maximized. When the lower positioning plate (30-5) at the lower part of the unit movable splint fixing frame (23) contacts the positioning block (30-6), the telescopic rod of the clamping cylinder (18) continues to extend downward. At this time, the clamping cylinder (18) is driven by the telescopic rod to rise vertically in the opposite direction along the light rod section of the screw rod (30-1) through the guide plate (30-4), thereby driving the unit movable splint fixing frame (23) and the unit movable splint (22) at the front end of the unit movable splint fixing frame (23) to move upward. The control system instructs the moving cylinder (16) to move in the opposite direction and also instructs the plate pushing cylinder (13-1) to move. The plate pushing cylinder (13-1) pushes the fixed plate (13-3). The fixed plate (13-3) drives the guide trolley (13-6) to move along the longitudinal slide rail (14) in the direction of the plywood outgoing board. At this time, the connecting frames (13-2) at both ends of the fixed plate (13-3) rotate relative to each other with the hinge shaft (13-4) as the axis under the pull of the fixed plate (13-3), thereby driving the two connecting frames (13-2) at the other ends of the machine The manipulator fixed shaft (11) rotates relatively, and the manipulators (10) fixed at intervals on the manipulator fixed shaft (11) swing under the rotation of the manipulator fixed shaft (11) and push the hot-pressed veneer plywood between the adjacent unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), and (5-7) to gradually move in the board-out direction until the plywood is pushed out; because the veneer plywood is pushed by the rotating plate-pushing robot (61) and the plate clamping automatic moving device (64), the large-area veneer plywood that has been hot-pressed can be quickly removed;

[0104] After removal, the control system commands the rotary push plate robot (61) and the plate clamping and automatic moving device (64) to return to their original positions. The push plate oil cylinder (13-1) drives the fixed plate (13-3) to move in the reverse direction. The connecting frames (13-2) at both ends of the fixed plate (13-3) rotate away from each other with the hinge shaft (13-4) as the axis under the drive of the fixed plate (13-3). The manipulator fixed shaft (11) at the other end of the connecting frame (13-2) rotates in the reverse direction, and the manipulator (10) returns to the front of the hot pressing space between the unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7) under the rotation drive of the manipulator fixed shaft (11). The push plate oil cylinder (13-1) then stops. The control system commands the lifting oil cylinder (12-1) to return to its original position. The lifting oil cylinder (12-1) drives the lifting shaft (12-2) to descend along the upper guide sleeve (12-4) and the lower guide sleeve (12-5). At the same time, the lifting shaft (12-2) drives the manipulator fixed shaft (11) to move downward through the upper connecting arm (12-6) and the lower connecting arm (12-7). When the manipulator (10) on the manipulator fixed shaft (11) descends to the front of the unit hot pressing plates (5-1), (5-2), (5-3), (5-4), (5-5), (5-6), (5-7), it stops.

[0105] The control system continues to command the clamping plate feeding device to act, repeating the above actions to convey the veneered plywood to be hot pressed in the feeding and storing plate device (60) into the hot pressing device (62). The specific steps are the same as the above actions and will not be elaborated here.

[0106] For the veneered plywood that has been hot pressed in the discharging and storing plate device (63), similarly, it is also automatically controlled by the control system. That is, the control system commands the left lifting oil cylinder (56-8-2-3) and the right lifting oil cylinder (56-8-2-3) to descend successively by a set height. When the plywood on the left unit pallet and the right unit pallet in each space falls onto the discharging conveying device (56), the control system commands the discharging servo motor (58-4) to act, driving the chain (58-2) to rotate. The hook plate (58-9) on the chain (58-2) hooks the hot pressed plywood and moves it towards the clamping and conveying device (57) under the drive of the chain (58-2). During the movement, the plywood is supported by the chain bracket (58-3) at the lower end of the chain (58-2) so that the plywood moves in a horizontal state. When the plywood moves into the clamping and conveying device (57), it is clamped and driven to be conveyed into the stacking device through the relative movement of the discharging roller (57-5) and the discharging pressure wheel (57-6).

[0107] When the plywood is conveyed to the automatic stacking device (56), the plywood is positioned on the discharging lifting table (56-8) through the rear baffle and the centering devices on both sides.

[0108] When the glued boards are stacked on the conveyor output device (56-8-4) at the upper end of the support platform (56-8-3) to a certain thickness in sequence, after the control system receives the information uploaded by the signal switch provided on the stacking frame (56-1), the control system commands the folding lifting mechanism (56-8-2) to act, driving the support platform (56-8-3) to descend to the set height and then stop. Then, it continues to stack the hot-pressed glued boards conveyed by the clamping and conveying device for stacking boards (57). When the control system receives the uploaded information again, the control system commands the folding lifting mechanism (56-8-2) to descend by the set height. Repeat the above actions in sequence until the folding lifting mechanism (56-8-2) folds onto the base (56-8-1). Then, the control system commands the support cylinder (56-4) to act, driving the rear baffle (56-3) to lift. At this time, the mobile device is docked with the board output lifting table (56-8). After docking, the control system commands the board output motor (56-8-4-5) to act, driving the output driving sprocket (56-8-4-1) and the output chain (58-2) to rotate, driving a stack of glued boards on the output chain (58-2) to move onto the mobile device, greatly reducing the manual handling intensity.

[0109] Due to adopting the above structure, the present invention has the advantages of novel structure, high degree of automation, no need for manual handling, high processing quality, high working efficiency, fast infeed and outfeed speed, high hot-pressing working efficiency, time-saving and labor-saving, fast stacking speed, high stacking quality, and fast output speed.
