In this way, the operator does not need to place the sheet manually, and this operation method greatly improves the flexibility of the entire operation process.

[0039] 2. When the drive device is started, it will begin to play its unique role. It can effectively drive the flip plate to perform the flip operation with the help of the guiding function of the guide component. In this process, the sheet placed in the sheet placement slot will be accurately clamped out and then steadily pushed into the multi-layer hot press. After the sheet is placed, the drive part has the ability to rotate the intermittent wheel under the drive of the short shaft rotation. As the intermittent wheel rotates, the sleeve will move up and down along the round rod. This action will drive the lifting plate to adjust the height, so that the sheet can be placed on the hot pressing plates of different heights in the multi-layer hot press, which enhances the effectiveness of auxiliary placement of the sheet, and through this series of precise operations, the entire hot pressing forming process is smoother and more efficient, and ultimately achieves the purpose of improving the efficiency of hot pressing forming.

[0040] 3. When the clamping assembly is clamping the sheet material and pushing it into the multi-layer hot press, the infrared sensor will be triggered, and the infrared sensor will drive the second telescopic device to start through the controller, so that the movable end of the second telescopic device will extend to push the rack. During the movement of the rack, the threaded rod can be driven to rotate through the gear, so that the limit plate rises from the limit groove to limit the sheet material placed on the hot pressing plate. When the flip plate is retracted, the rack returns to its original state. At this time, the limit plate is also retracted into the limit groove to prevent the sheet material from being offset due to placement, resulting in poor hot pressing effect, thereby improving the quality of hot pressing.

[0041] 4. By setting the reset component, the following effect is achieved: when the second telescopic device is in the unextended and pushed state, the first spring can play its role, prompting the rack to move along the sliding groove, and finally restoring the entire device to its original state, so that the limit plate can be put into use again.

[0056] The specific implementation of a hot pressing forming system for forming a multi-layer building formwork according to the present invention will be further described below in conjunction with the accompanying drawings.

[0057] like Figure 1-Figure 13As shown, a hot pressing forming system for forming multi-layer building formwork is mainly used to place the sheet materials on the multi-layer hot press machine 1 without manual lifting, thus saving manpower. In this embodiment, when in use, the operator only needs to place the processed sheet materials in the sheet material placement groove 10, and then the device can automatically clamp the sheet materials out of the sheet material placement groove 10, flip it over and push it into the multi-layer hot press machine 1, thereby improving the efficiency of hot pressing forming.

[0058] In this embodiment, the hot pressing forming system includes a multi-layer hot press machine 1. In this embodiment, the structure and principle of the multi-layer hot press machine 1 are prior art and will not be described in detail here. The hot pressing forming system also includes a U-shaped base 2 arranged on the left side of the multi-layer hot press machine 1. Through the setting of the U-shaped base 2, the device can be supported so that it can be more stably supported near the multi-layer hot press machine 1, so as to stably place and take out the sheet materials from the multi-layer hot press machine 1.

[0059] like Figure 4 , Fig. 9 and Fig.10 As shown, a lifting plate 4 is provided above the U-shaped base 2 , and a sheet material placement groove 10 is fixedly provided on the lifting plate 4 , so that the sheets are arranged vertically in the sheet material placement groove 10 .

[0060] Specifically, the sheet material placement slot 10 is a groove structure with an opening facing upward. In the present embodiment, the space of the sheet material placement slot 10 is large enough. When the sheet material is taken out, it can be tilted out from the sheet material placement slot 10 to avoid the sheet material placement slot 10 blocking the taking out of the sheet material. The sheet material placement slot 10 is hingedly connected with an opening and closing door on the side away from the multi-layer hot press 1. When the operator places the sheet material, the opening and closing door is opened, and then the sheet material is vertically arranged in the sheet material placement slot 10. After placement, the opening and closing door is closed. A telescopic elastic member 24 is fixedly provided in the sheet material placement slot 10. The telescopic elastic member 24 presses on the side of the sheet material to push the sheet material directly under the clamping assembly 12. Through the setting of the telescopic elastic member 24, the sheet material can be pressed so that the sheet material close to the opening and closing door can be conveniently taken out.

[0061] In this embodiment, the telescopic elastic member 24 includes a telescopic sleeve composed of a multi-section telescopic sleeve set and a fifth spring arranged in the telescopic sleeve. The structure and principle of the telescopic elastic member 24 are prior art and will not be described in detail here.

[0062] like Figure 1-Figure 5 As shown, a flip mechanism is provided on the lifting plate 4, and the lifting plate 4 is connected to the flip mechanism through a first fixed column 5, and the flip mechanism is connected to the flip plate 6. A driving device 7 is fixed at the bottom of the lifting plate 4, and the driving device 7 is connected to the flip mechanism so that the flip plate 6 can be flipped from a vertical state to a horizontal state. In this embodiment, the driving device 7 adopts a motor, and the structure and principle of the motor are prior art, which will not be described in detail here.

[0063] Specifically, the flipping mechanism includes a short shaft 17 that is transmission-connected to the driving device 7, a third telescopic device 18 that is rotationally connected to the first fixed column 5, and a guide assembly 19 that is transmission-connected between the short shaft 17 and the third telescopic device 18. When the short shaft 17 rotates, it can drive the guide assembly 19. The third telescopic device 18 adopts an electric telescopic rod or a hydraulic telescopic rod. The structure and principle of the electric telescopic rod or the hydraulic telescopic rod are prior art and are not described in detail herein. A rotating block 20 is rotationally provided on the first fixed column 5, and a sliding hole that is transparent front and back is opened at the fixed end of the third telescopic device 18. The rotating block 20 guides and slides in the sliding hole; the short shaft 17 is rotationally provided on the second fixed frame 8; the end of the third telescopic device 18 away from the rotating block 20 is fixedly connected to the flip plate 6. In this embodiment, the setting of the rotating block 20 can limit the sliding direction of the third telescopic device 18, so as to take the sheet material and feed it to the multi-layer hot press 1.

[0064] In this embodiment, a sixth bevel gear is fixed to the output end of the driving device 7, and a transmission rod is rotatably connected to the bottom of the lifting plate 4 through a support, and a seventh bevel gear meshing with the sixth bevel gear is fixed on the transmission rod. Driving wheels are fixed on both ends of the transmission rod, and a driven wheel is fixed on the short shaft 17. The driving wheel and the driven wheel are connected by a belt drive to rotate the short shaft 17, and a through hole is opened on the lifting plate 4 for the belt to pass through.

[0065] The guide assembly 19 includes a first link 1901 fixedly connected to the short shaft 17, a second link 1902 hingedly connected to the first link 1901, and a third link 1903 hingedly connected to the second link 1902. When the short shaft 17 rotates, the first link 1901 can be driven to rotate. When the first link 1901 rotates, the second link 1902 can be driven to rotate. When the second link 1902 rotates, the third link 1903 can be driven to rotate. A third fixing column is fixedly provided on the lifting plate 4. The connecting rod 1903 is rotatably arranged on the third fixed column; a connecting rod 21 is fixedly connected between the two third connecting rods 1903, and the connecting rod 21 is inserted in the third fixed column. When the third connecting rod 1903 rotates, it can drive the connecting rod 21 to rotate. A fourth connecting rod 31 is fixed on the connecting rod 21, and the fourth connecting rod 31 is hingedly connected to the third telescopic device 18. When the connecting rod 21 rotates, it drives the fourth connecting rod 31 to rotate, so that the fourth connecting rod 31 drives the third telescopic device 18 to rotate around the first fixed column 5.

[0066] In this embodiment, when the third telescopic device 18 is turned to a vertical state, the sheet material in the sheet material placement slot 10 can be taken out by the clamping assembly 12. Fig.11 shown.

[0067] Specifically, the clamping assembly 12 includes a fixed frame 1201 fixed on the flip plate 6, a bidirectional lead screw 1202 arranged in the fixed frame 1201, and a clamping plate 1203 that is transmission-connected to the bidirectional lead screw 1202; both ends of the bidirectional lead screw 1202 are installed on the fixed frame 1201 through a support seat; a motor 25 is fixedly provided on the side wall of the fixed frame 1201. In this embodiment, the structure and principle of the motor 25 are prior art and are not described in detail herein. The output end of the motor 25 is transmission-connected to the bidirectional lead screw 1202. Both threaded sections of the bidirectional lead screw 1202 are threadedly adapted to be equipped with a slider 29. An inclined rod 30 is hingedly connected to the slider 29. The inclined rod 30 is hingedly connected to the clamping plate 1203. When the bidirectional lead screw 1202 rotates, it can drive the two sliders 29 to move in opposite directions, so as to drive the clamping plate 1203 to move along the direction of the fixed frame 1201 through the inclined rod 30 to clamp the sheet material.

[0068] In this embodiment, a rubber sheet is fixedly provided on one side opposite to the clamping plate 1203 so as to clamp the sheet material more stably.

[0069] In this embodiment, two active transmission wheels are fixedly provided at the output end of the motor 25, and each bidirectional lead screw 1202 passes through the fixed frame 1201 and is fixed with a driven transmission wheel. The active transmission wheel is connected to the corresponding driven transmission wheel through a belt to rotate the bidirectional lead screw 1202.

[0070] like Figure 1-Figure 3 As shown, when the two clamping plates 1203 clamp the sheet material and flip it over and push it into the multi-layer hot press 1, when the flip plate 6 is in a horizontal state, the third telescopic device 18 can be driven to start, so that the flip plate 6 and the clamping assembly 12 are pushed into the multi-layer hot press 1.

[0071] like Figure 1-Figure 3 , Fig.12 and Fig.13 As shown, in the process of clamping the sheet material and pushing it toward the multi-layer hot press machine 1, the limiting assembly will be driven to start, so that the limiting plate 15 will rise from the hot press plate 14, and the sheet material placed on the hot press plate 14 will be limited to avoid the sheet material from being offset when placed, resulting in poor quality of hot pressing molding of the sheet material.

[0072] Specifically, the multi-layer hot press machine 1 includes a plurality of groups of hot pressing plates 14 spaced apart and arranged horizontally in an upper and lower manner. A limit groove opening upward is provided on the top of the hot pressing plate 14, and a limit plate 15 is provided in the limit groove. A limit assembly capable of driving the limit plate 15 to move up and down along the limit groove is provided in the hot pressing plate 14. A second telescopic device 16 extending in the left and right directions is fixedly provided on the second fixed frame 8. In this embodiment, the second telescopic device 16 adopts an electric telescopic rod or a hydraulic telescopic rod. The structure and principle of the electric telescopic rod or the hydraulic telescopic rod are prior art and will not be described in detail herein. An infrared sensor electrically connected to the second telescopic device 16 is provided on the second fixed frame 8. In this embodiment, the infrared sensor is control-connected to the second telescopic device 16 through a controller. This principle is prior art and will not be described in detail herein. When the infrared sensor detects the laterally moving sheet material, the movable end of the second telescopic device 16 is driven to push the limit assembly, so that the limit plate 15 extends out of the hot pressing plate 14 along the limit groove to limit the sheet material placed on the hot pressing plate 14.

[0073] The hot pressing plate 14 is provided with a cavity connected to the limiting groove, and the hot pressing plate 14 is provided with a sliding groove connected to the cavity and extending in the left and right directions on the side facing the lifting plate 4; the limiting assembly includes a rack 1301 guided to slide in the sliding groove, a gear 1302 rotating in the cavity and meshing with the rack 1301, and a threaded rod 1303 connected to the gear 1302 and arranged vertically. After the second telescopic device 16 is started, the movable end of the second telescopic device 16 can Insert it into the sliding groove and push the rack 1301. When the rack 1301 moves along the sliding groove, it can drive the gear 1302 to rotate, and the threaded rod 1303 is rotated on the inner wall of the cavity. A threaded plate that is threadedly adapted to the threaded rod 1303 is fixed on the limit plate 15. When the threaded rod 1303 rotates, it can drive the threaded plate on the limit plate 15 to move along the limit groove, and then drive the limit plate 15 to move up and down to pass through the hot pressing plate 14 and limit the sheet material.

[0074] In this embodiment, the gear 1302 is rotated in the cavity by a small rod, the eleventh bevel gear is fixed on the small rod, and the twelfth bevel gear is fixed on the threaded rod 1303. The eleventh bevel gear and the twelfth bevel gear are meshed with each other and can drive the threaded rod 1303 to rotate.

[0075] like Fig.12 As shown, after the sheet material is placed, the third telescopic device 18 is retracted. At this time, the infrared sensor cannot detect the sheet material moving laterally, so that the second telescopic device 16 is retracted to its initial state. In this embodiment, the structure and principle of this process are prior art and will not be described in detail here.

[0076] Specifically, a reset assembly 26 is provided in the slide groove to restore the rack 1301 to its initial position;

[0077] The reset assembly 26 includes a telescopic rod 2601 fixed on the side wall of the sliding groove and a first spring 2602 sleeved on the telescopic rod 2601; the other ends of the telescopic rod 2601 and the first spring 2602 are fixedly connected to the rack 1301; when the movable end of the second telescopic device 16 pushes the rack 1301 to move along the sliding groove, it can drive the gear 1302 to rotate to extend the limit plate 15 out of the limit groove. When the movable end of the second telescopic device 16 is separated from the rack 1301, the rack 1301 can be reset under the action of the first spring 2602 for next use.

[0078] like Figure 3-Figure 8 As shown, when the clamping assembly 12 is flipped over and the third telescopic device 18 is in a vertical state, the short shaft 17 drives the intermittent lifting assembly 9 to rotate, so that the lifting plate 4 can intermittently move up and down along the extension direction of the round rod 3.

[0079] Specifically, a plurality of vertically arranged round rods 3 are provided above the U-shaped base 2, the lifting plate 4 is sleeved on the round rods 3 and threadedly adapted with two of the round rods 3, a second fixed frame 8 is fixed on the top of the lifting plate 4, and the intermittent lifting assembly 9 is rotatably provided on the second fixed frame 8.

[0080] The intermittent lifting assembly 9 includes a rotating rod 901 rotatably arranged on the second fixed frame 8, an intermittent wheel 902 fixedly arranged on the rotating rod 901, and a driving member 903 fixedly arranged on the short shaft 17. In this embodiment, the driving member 903 includes a fan-shaped plate and a lever, the fan-shaped plate and the lever are fixedly connected, and a through hole adapted to the driving member 903 is opened on the intermittent wheel 902, and the through holes are arranged in a circular array around the axis of the intermittent wheel 902. In this embodiment, the through holes include fan-shaped holes adapted to the fan-shaped plate and lever holes adapted to the lever. When the driving member 903 rotates under the action of the short shaft 17, the intermittent wheel 902 can be toggled, and when the intermittent wheel 902 rotates, it can drive the first bevel gear 22 to rotate. The first bevel gear 22 is fixedly provided on the rotating rod 901, and the screw The two round rods 3 with threads are splined with a sleeve 27. In this embodiment, the spline connection is used to make the second bevel gear 23 rotate, which can also drive the round rod 3 with threads to rotate. When the lifting plate 4 moves up and down, the second bevel gear 23 can also move up and down along the round rod 3 with threads. The second bevel gear 23 is fixedly provided on the sleeve 27. Since the first bevel gear 22 and the second bevel gear 23 are meshed, the two round rods 3 with threads can be driven to rotate and the lifting plate 4 can be moved up and down; an L-shaped connecting plate 28 is provided on the sleeve 27, and the L-shaped connecting plate 28 is connected to the rotating rod 901. Through the setting of the L-shaped connecting plate 28, the second bevel gear 23 can be suspended to avoid the misalignment of the second bevel gear 23 and the second bevel gear 23.

[0081] A stopper is fixedly provided on the top of the round rod 3. The stopper can limit the rising height of the lifting plate 4 and prevent the lifting plate 4 from falling off.

[0082] Working principle: the operator places the processed sheet in the sheet placement groove 10 in the form of a vertical plate. After placing it, the opening and closing door is closed. Then, the driving device 7 is started, and the driving device 7 indirectly drives the short shaft 17 to rotate. When the short shaft 17 rotates, it can drive the first connecting rod 1901 to rotate. When the first connecting rod 1901 rotates, it can drive the second connecting rod 1902 to rotate. When the second connecting rod 1902 rotates, it can drive the third connecting rod 1903 to rotate. When the third connecting rod 1903 rotates, it can drive the connecting rod 21 to rotate. When the connecting rod 21 rotates, it drives the fourth connecting rod 31 to rotate, so that the fourth connecting rod 31 drives the third telescopic device 18 to rotate around the first fixed column 5. When the third telescopic device 18 is flipped to a vertical state, the driving motor 25 is started to rotate the bidirectional screw 1202. Then, when the bidirectional screw 1202 rotates, it can drive the two sliders 29 to move in opposite directions. The clamping plate 1203 is driven by the inclined rod 30 to move along the direction of the fixed frame 1201 to clamp the sheet material; when the sheet material is clamped, the third telescopic device 18 can be flipped into a horizontal state, and then the clamping assembly 12 clamps the sheet material and pushes it toward the multi-layer hot press 1. In the process of pushing it toward the multi-layer hot press 1, when the infrared sensor detects the transverse movement of the sheet material, the second telescopic device 16 is driven to start. After the second telescopic device 16 is started, the movable end of the second telescopic device 16 can be inserted into the sliding groove and push the rack 1301. When the rack 1301 moves along the sliding groove, it can drive the gear 1302 to rotate. When the gear 1302 rotates, it can indirectly drive the threaded rod 1303 to rotate. When the threaded rod 1303 rotates, it can drive the threaded plate on the limit plate 15 to move along the limit groove, thereby driving the limit plate 15 to move up and down to pass through the hot pressing plate 14 and limit the sheet material.

[0083] After the sheet is placed, the third telescopic device 18 starts to retract, and the infrared sensor cannot detect the laterally moving sheet, so that the second telescopic device 16 is retracted to its initial state; at this time, when the movable end of the second telescopic device 16 disengages from the rack 1301, the rack 1301 can be reset under the action of the first spring 2602 for next use.

[0084] After the third telescopic device 18 is retracted and turned over to take the sheet again, the short shaft 17 can also drive the driving member 903 to rotate to turn the intermittent wheel 902. When the intermittent wheel 902 rotates, it can drive the first bevel gear 22 to rotate. Since the first bevel gear 22 and the second bevel gear 23 are meshed, the two round rods 3 with threads can be driven to rotate, so that the lifting plate 4 can be lifted up and down, so as to place the sheet on the hot pressing plates 14 of different heights in the multi-layer hot press 1, thereby achieving the purpose of convenient placement of the sheet.

[0085] When the sheet material needs to be taken out after hot pressing and forming, the above operation is repeated to take out the sheet material after hot pressing and forming on the hot pressing plate 14 and place it in the sheet material placement groove 10 to facilitate the taking out of the sheet material.

[0086] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to use the device to drive manual work to pick up and place sheet materials, thereby improving the efficiency of sheet hot pressing. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
