However, the hot press in the prior art does not have a relevant mechanism for buffering and absorbing shocks for the lower pressing plate, resulting in the lower pressing plate not having the effect of buffering and absorbing shocks caused by the upper pressing plate when in use, which will affect the stable operation of the laminating work of the upper and lower pressing plates, so that the hot press still has certain disadvantages during use.

By arranging a plurality of shock absorbing springs 9 and a damping rod 10 at the bottom of one of the mounting plates 8 located below, a certain buffering and shock absorbing effect can be achieved on the pressure generated by the downwardly moving upper pressing plate 5, the pressure on the lower pressing plate 6 and the lower mounting plate 8 can be reduced, and the service life of the lower pressing plate 6 and the lower mounting plate 8 can be improved.

[0026] As a technical optimization solution of the present invention, a telescopic cylinder 4 is installed on the top of the machine body 1, and the telescopic end of the telescopic cylinder 4 passes through the machine body 1 and is connected to another mounting plate 8. During the telescopic process, the telescopic end of the telescopic cylinder 4 can drive the upper mounting plate 8 and the upper pressing plate 5 to move up and down synchronously inside the machine body 1.

[0027] As a technical optimization solution of the present invention, two slide grooves 11 are provided on the top of the fixed plate 2, and sliders 12 are installed inside the two slide grooves 11, and first electric telescopic rods 13 are installed on the top of the two sliders 12, and connecting plates 14 are installed at the telescopic ends of the two first electric telescopic rods 13, and the ends of the two connecting plates 14 away from the first electric telescopic rods 13 are connected to one of the rectangular plates 15. Linear motors are preset inside the two slide grooves 11, and the two linear motors can drive the two sliders 12 to move back and forth inside the corresponding slide grooves 11, and drive the two first electric telescopic rods 13, the connecting plates 14, one of the rectangular plates 15, the two rotating plates 16 and the other rectangular plate 15 to move and adjust together on the top of the fixed plate 2; in the process of moving up and down, the telescopic ends of the two first electric telescopic rods 13 can drive the two connecting plates 14, the two rectangular plates 15 and the two rotating plates 16 to move and adjust together.

[0028] As a technical optimization solution of the present invention, a rectangular rod 17 is installed on the outer wall of one side of the two rectangular plates 15, and a first groove 18 is opened on the outer wall of one side of the two rectangular rods 17, and a double-headed screw 19 is rotatably installed inside the two first grooves 18.

[0029] As a technical optimization solution of the present invention, the outer walls of the two double-headed screws 19 are threadedly mounted with two moving blocks 20, and both ends of the two rotating plates 16 are rotationally connected to the moving blocks 20 close to them. When the two double-headed screws 19 rotate, they can drive the corresponding two moving blocks 20 to move in the direction of approaching or moving away, and drive the two rotating plates 16 to move and adjust synchronously in the direction of approaching or moving away; and the second driving motors are preset inside the two moving blocks 20, and the output ends of the two second driving motors are respectively connected to the rotating parts of the two rotating plates 16, so as to drive the two rotating plates 16 to rotate and adjust between the corresponding two moving blocks 20.

[0030] As a technical optimization solution of the present invention, the first cleaning mechanism includes a plurality of exhaust ports 23 opened at the bottom of the two rotating plates 16. The two rotating plates 16 are both hollow, and the two rotating plates 16 are connected to external preset jet equipment through pipes. The high-pressure gas generated by the external preset jet equipment can be transported to the inside of the two rotating plates 16 through two pipes, and ejected outward through the plurality of exhaust ports 23, so as to clean the surface of the plate to be hot-pressed.

[0031] As a technical optimization solution of the present invention, a first cleaning pad 21 and a second cleaning pad 22 are respectively installed on the top and one side outer wall of the two rotating plates 16, and the first cleaning pad 21 and the second cleaning pad 22 are both made of soft materials. After the plate to be hot-pressed is placed on the top of the two rotating plates 16, as the two rotating plates 16 move back and forth in the direction of approaching or moving away from each other, the first cleaning pads 21 on the top of the two rotating plates 16 are driven to automatically clean the bottom of the plate.

[0032] As a technical optimization solution of the present invention, the second cleaning mechanism includes two second grooves 24 opened inside one of the rectangular plates 15, two second electric telescopic rods 25 are installed on the inner wall of one side of the two second grooves 24, and the telescopic ends of the two second electric telescopic rods 25 are jointly installed with a scraper 26. During the telescopic process, the telescopic ends of the two second electric telescopic rods 25 can drive the scraper 26 to extend and retract inside the second groove 24.

[0033] As a technical optimization solution of the present invention, the ends of the two scrapers 26 close to the upper pressing plate 5 and the lower pressing plate 6 are both provided with sharp parts 28, and the outer walls of the two scrapers 26 away from each other are both installed with third cleaning pads 27. The sharp parts 28 provided at one end of the two scrapers 26 cooperate with other components to clean the plates adhered to the side close to the upper pressing plate 5 and the lower pressing plate 6; the surfaces of the two sharp parts 28 are both provided with rubber layers, which can avoid damage to the upper pressing plate 5 and the lower pressing plate 6.

[0034] In the present invention, when the user uses the device, the two sliders 12 are located at the end of the fixed plate 2 away from the body 1, driving the two rectangular plates 15 and the rotating plate 16 and other components to be located above the fixed plate 2. According to the length of the multiple plates to be hot-pressed, the two double-headed screws 19 are controlled to drive the two moving blocks 20 to move and adjust in the direction of approaching or moving away from each other, and the spacing between the two rotating plates 16 is adjusted accordingly, so that the two ends of the multiple plates to be hot-pressed can be stably placed on the top of the two rotating plates 16, and after placing the multiple stacked plates on the top of the two rotating plates 16, the two sliders 12 are controlled to move in the direction close to the body 1, driving the two rectangular plates 15 and the two rotating plates 16 to enter the interior of the body 1 together, and are located between the upper pressing plate 5 and the lower pressing plate 6. At this time, by controlling the two double-headed screws 19 to rotate forward and backward, driving the two rotating plates 16 to move back and forth at the bottom of the multiple plates, the two first cleaning pads 21 can be driven to automatically clean the bottom of the plates, ensuring that the contact surface between the bottom of the subsequent plates and the lower pressing plate 6 is relatively clean.

[0035] After the two first cleaning pads 21 clean the bottom of the plate, the two rotating plates 16 are as follows: Figure 3 In the state shown, the telescopic ends of the two first electric telescopic rods 13 can be controlled to retract downward together, driving the distance between the two rotating plates 16 and the lower pressure plate 6 to shorten to the minimum state, and then as the two rotating plates 16 move away from each other to the maximum distance, the multiple plates placed on the top of the two rotating plates 16 fall downward on the top of the lower pressure plate 6, thereby achieving the effect of automatic loading of multiple plates to be hot pressed, without the need for manual loading of the plates, thereby improving the safety and efficiency of the plate loading process.

[0036] After the multiple plates fall on the top of the lower pressing plate 6, the multiple exhaust ports 23 arranged at the bottom of the two rotating plates 16 face the top of the plates. By controlling the start of the external preset jet device, the high-pressure gas discharged from the multiple exhaust ports 23 at the bottom of the two rotating plates 16 is sprayed downward on the top of the multiple plates. In combination with the back-and-forth movement of the two rotating plates 16, the impurities attached to the top of the plates can be cleaned and removed. If the impurities attached to the top of the plate cannot be cleaned up by the multiple exhaust ports 23, one of the rotating plates 16 can be controlled to rotate 90 degrees counterclockwise and the other rotating plate 16 can be controlled to rotate 90 degrees clockwise, so that the second cleaning pads 22 arranged on the outer walls of one side of the two rotating plates 16 are rotated to the bottom, and the telescopic ends of the two first electric telescopic rods 13 continue to shrink, thereby driving the two second cleaning pads 22 to abut against the top of the plate. As the two rotating plates 16 move back and forth, the two second cleaning pads 22 can be used to wipe off the impurities on the top of the plate that cannot be blown away by the high-pressure gas, thereby ensuring that the cleanliness of the top of the plate is high, so that the contact surface between the top of the subsequent plate and the upper pressing plate 5 is relatively clean, thereby ensuring that the upper pressing plate 5 has a better hot pressing effect on the plate.

[0037] At the same time, after placing the multiple plates to be hot-pressed on top of the two rotating plates 16, since the two rotating plates 16 are preset with electric heating blocks inside, the heat generated by the electric heating blocks can be transferred to the inside of the plates while the two rotating plates 16 clean the bottom and top of the plates, and can be transferred to the inside of the plates by jetting air toward the plates through multiple exhaust ports 23, thereby preheating the plates to be hot-pressed, improving the quality and efficiency of the subsequent hot pressing of multiple plates by the upper pressing plate 5 and the lower pressing plate 6, and avoiding cracks in the plates during the hot pressing process. The above cleaning process can be selected according to actual work needs. If cleaning is not required, the plates can be directly placed for hot pressing.

[0038] After the multiple plates are cleaned and preheated, the two sliders 12 are controlled to drive the two rectangular plates 15, the rotating plate 16 and other components to move to the top of the fixed plate 2, and then the telescopic end of the telescopic cylinder 4 is controlled to extend to drive the upper pressing plate 5 to move downward, and the multiple plates placed on the top of the lower pressing plate 6 are subjected to hot pressing treatment. After the upper pressing plate 5 and the lower pressing plate 6 cooperate to perform hot pressing processing on the multiple plates, the upper pressing plate 5 moves upward and resets, and the two sliders 12 are controlled to drive the two rectangular plates 15 and the rotating plate 16 to move between the upper pressing plate 5 and the lower pressing plate 6 again, first control one of the rotating plates 16 to rotate 180 degrees counterclockwise, and then control the other rotating plate 16 to rotate 180 degrees clockwise, so that the first cleaning pads 21 on the top of the two rotating plates 16 are rotated to the bottom, and the second cleaning pads 22 on one side of the two rotating plates 16 are rotated to a close position, and the telescopic ends of the two first electric telescopic rods 13 are controlled to extend and retract, driving the two rotating plates 1 The bottom end of 6 moves to a state flush with the top of the lower pressing plate 6, and with the help of the rotation of the two double-headed screws 19, the two rotating plates 16 are driven to move in the direction of approaching each other, so that the outer wall of one side of the two rotating plates 16 with the second cleaning pad 22 abuts against the two sides of the hot-pressed plate, and has a flexible clamping effect on the two sides of the plate. After the two rotating plates 16 stably clamp the hot-pressed plate, the telescopic ends of the two first electric telescopic rods 13 are controlled to extend upward together, driving the two rectangular plates 15 to move upward to a position higher than the lower pressing plate 6, and then the two sliders 12 are controlled to move in the direction away from the machine body 1, which can synchronously drive the hot-pressed plate to move out from the inside of the machine body 1. The plate between the two rotating plates 16 can be taken manually or by a preset manipulator, so as to realize the effect of automatic unloading of the hot-pressed plate, improve the efficiency of plate unloading, and avoid the problem of low safety of manually taking the plate on the top of the lower pressing plate 6.

[0039] By arranging a plurality of shock-absorbing springs 9 and damping rods 10 at the bottom of one of the mounting plates 8 located below, a certain buffering and shock-absorbing effect can be achieved on the pressure generated by the downwardly moving upper pressure plate 5, thereby reducing the pressure on the lower pressure plate 6 and the lower mounting plate 8, and improving the service life of the lower pressure plate 6 and the lower mounting plate 8.

[0040] When the upper pressing plate 5 and the lower pressing plate 6 need to stop and rest for a period of time after working for a long time, the two sliders 12 can be controlled to drive the two rotating plates 16 to move between the upper pressing plate 5 and the lower pressing plate 6, and the external preset jet equipment can be controlled to start so that the multiple exhaust ports 23 can spray out low-temperature gas together, and the two rotating plates 16 can be controlled to rotate and adjust between the corresponding two moving blocks 20, and the two rotating plates 16 can be controlled to move back and forth so that the low-temperature gas discharged from the multiple exhaust ports 23 can be blown onto the upper pressing plate 5 and the lower pressing plate 6 respectively, which can accelerate the heat dissipation of the upper pressing plate 5 and the lower pressing plate 6 and facilitate the subsequent use of the upper pressing plate 5 and the lower pressing plate 6.

[0041] If it is necessary to clean the outer wall of the side close to the upper pressing plate 5 and the lower pressing plate 6 to ensure a good subsequent hot pressing effect on the plate, the two sliders 12 can be controlled to drive the two rectangular plates 15 to enter the interior of the machine body 1, and the telescopic ends of the two first electric telescopic rods 13 can be controlled to drive the height of the two rectangular plates 15 to adjust to ensure that the bottom ends of the two rectangular plates 15 are higher than the top of the lower pressing plate 6, and then the telescopic end of the telescopic cylinder 4 is controlled to extend downward to drive the bottom end of the upper pressing plate 5 to move downward to a position higher than the top of the rectangular plate 15, and then the extension end of the plurality of second electric telescopic rods 25 is controlled to extend downward. The contracted ends extend together, driving the two scrapers 26 to extend from the corresponding second grooves 24, so that the third cleaning pads 27 arranged on the side away from the two second scrapers 26 respectively contact the outer wall on the side close to the upper pressing plate 5 and the lower pressing plate 6, and as the two sliders 12 move in the direction away from the body 1, the two third cleaning pads 27 are driven to clean the outer wall on the side close to the upper pressing plate 5 and the lower pressing plate 6, respectively, to ensure that the outer wall on the side close to the upper pressing plate 5 and the lower pressing plate 6 are in a clean state, thereby reducing the adverse effects of impurities on the hot pressing process of the plates.

[0042] If uneven hot pressing of the plate occurs after the upper pressing plate 5 and the lower pressing plate 6 are hot pressed, resulting in the plate adhering to the surface of the upper pressing plate 5 or the lower pressing plate 6, then after the two rectangular plates 15 and the rotating plate 16 are moved to the inside of the machine body 1, the two rotating plates 16 can be controlled to rotate and adjust according to the position where the plate adheres to the surface of the upper pressing plate 5 or the lower pressing plate 6, so that the multiple exhaust ports 23 can spray low-temperature gas toward the plate, and cooperate with the movement and adjustment of the two rotating plates 16 to drive the multiple exhaust ports 23 to evenly discharge the low-temperature gas to the surface of the plate, ensuring that the plate is cooled and solidified. After the state is reached, the telescopic ends of the two first electric telescopic rods 13 are controlled to extend and retract, driving the two rectangular plates 15 to be located between the upper pressing plate 5 and the lower pressing plate 6. According to the position of the plates, the telescopic ends of the two corresponding second electric telescopic rods 25 are controlled to extend, driving the corresponding scrapers 26 to extend from the inside of the second groove 24. As the two sliders 12 move toward the end away from the body 1, the sharp parts 28 of the scrapers 26 are driven to scrape and clean the plates attached to the surface of the upper pressing plate 5 or the lower pressing plate 6, avoiding the problem that it is inconvenient to clean them manually and affecting the hot pressing efficiency of the hot press machine on the plates.

[0043] When the hot press is not in use, in order to prevent moisture in the working area from corroding the upper pressing plate 5 and the lower pressing plate 6, the staff needs to dehumidify the interior of the body 1 regularly. After the hot press is used for the last time, the two sliders 12 are controlled to drive the two rectangular plates 15 and the rotating plate 16 to enter the interior of the body 1, and the two rotating plates 16 are controlled to move to the maximum distance in the direction of moving away from each other, and the two rotating plates 16 are controlled to rotate 90 degrees, so that the side of the two rotating plates 16 with the exhaust port 23 rotates to a close position, the upper pressing plate 5 is controlled to move downward to abut against the top of the lower pressing plate 6, and then the two rotating plates 16 are controlled to move in the direction of approaching to abut against the fitting parts of the upper pressing plate 5 and the lower pressing plate 6. When it is necessary to dehumidify the upper pressing plate 5 and the lower pressing plate 6, the electric heating blocks inside the two rotating plates 16 are directly controlled to start, and the heat is transferred to the interior of the upper pressing plate 5 and the lower pressing plate 6 to achieve automatic dehumidification, without the need for manual tools or opening the hot press for dehumidification.
