DETAILED DESCRIPTION

[0019] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0020] The embodiment of the present application discloses a plywood hot-pressing device for facilitating limiting adjustment. Referring to Figure 1 and Figure 4 The plywood hot-pressing device for facilitating limiting adjustment comprises a hot-pressing table 10, a side limiting assembly 20 and an end limiting assembly 30 installed in the hot-pressing table 10. The upper portion of the hot-pressing table 10 is provided with a hot-pressing plate 11, and the hot-pressing plate 11 is driven to be movably arranged on the hot-pressing table 10 by means of a plurality of hydraulic jacking assemblies 12. After the conveying belt conveys the plywood to be hot-pressed onto the hot-pressing table 10, the end limiting assembly 30 can be used to position and block the end of the plywood to be hot-pressed, so that the end of the plywood to be hot-pressed is aligned and flatly rested on the hot-pressing table 10. Then the side limiting assembly 20 can be used to limit the two sides of the plywood to be hot-pressed, so that the side edges of the plywood to be hot-pressed are aligned and flat, and finally the hot-pressing plate 11 can be used to hot-press the plywood.

[0021] Referring to Figure 1 and Figure 2The side limiting assembly 20 has two symmetrically distributed first limiting plates 21, and a moving shaft 22 is fixedly arranged at the middle part of each first limiting plate 21. The hot-pressing table 10 is formed with two first guide grooves 13 penetrating through the top of the hot-pressing table 10 along the width direction of the hot-pressing table 10, the width of the first guide groove 13 is matched with the diameter of the moving shaft 22, and the length of the first guide groove 13 is greater than the diameter of the moving shaft 22, so that when each moving shaft 22 is slidingly arranged in one first guide groove 13, the first limiting plate 21 connected with the moving shaft 22 can be simultaneously driven to move along the width direction of the hot-pressing table 10. The side limiting assembly 20 further comprises a first adjusting part arranged in the hot-pressing table 10 and used for driving the two moving shafts 22 to move, and the first adjusting part is used for driving the two moving shafts 22 to move towards each other or away from each other.

[0022] In the embodiment, the first adjusting part can comprise two push rods 23, an oscillating rod 24, a rotating shaft 25, a first motor 26, a worm 27 and a worm wheel 28. One end of each push rod 23 is rotatably connected with one moving shaft 22, and the other end of each push rod 23 is rotatably connected with one end of the oscillating rod 24. The middle part of the oscillating rod 24 is sleeved on the rotating shaft 25 and rotatably connected with the inner wall of the top of the hot-pressing table 10 by the rotating shaft 25, so that when the oscillating rod 24 is deflected, the moving shaft 22 connected with the push rod 23 can be driven to move along the length direction of the first guide groove 13 under the guidance of the first guide groove 13. The first motor 26 is fixedly arranged in the hot-pressing table 10, the output end of the first motor 26 is connected with the worm 27, the worm 27 and the worm wheel 28 are meshed with each other, and the worm wheel 28 is sleeved on the outside of the rotating shaft 25 and fixedly connected with the rotating shaft 25, so that when the first motor 26 drives the worm to rotate, the rotating shaft 25 and the oscillating rod 24 can be simultaneously driven to deflect by the worm wheel 28. In addition, the self-locking cooperation of the worm 27 and the worm wheel 28 can prevent the two first limiting plates 21 from moving away after limiting the plywood.

[0023] Referring to Figure 1 and Figure 3 , the end limiting assembly 30 has a second limiting plate 31, and the hot-pressing table 10 is formed with a second guide groove penetrating through the top of the hot-pressing table 10, and the length and width of the second guide groove are matched with the length and width of the second limiting plate 31, so that the second limiting plate 31 can move along the height direction of the second guide groove. The second limiting plate 31 is located behind the two first limiting plates 21, and the end limiting assembly 30 further comprises a second adjusting part arranged in the hot-pressing table 10 and used for driving the second limiting plate 31 to move, so that the second limiting plate 31 can position the end of the plywood.

[0024] In the embodiment, the second adjusting part comprises a sliding seat 32, a guide rod 33, a second motor 34, a screw rod 35, a screw seat 36 and a set of connecting arms 37. The sliding seat 32 is formed at the bottom of the second limiting plate 31, and the sliding seat 32 is sleeved on the guide rod 33, so that the sliding seat 32 can drive the second limiting plate 31 to adjust the height when the sliding seat 32 moves below the second guide groove. The upper end of the guide rod 33 is fixedly connected with the inner wall of the top of the hot pressing table 10, and the screw rod 35 penetrates through the lower end of the guide rod 33 and is rotatably connected with the guide rod 33. The screw seat 36 is sleeved on the screw rod 35 and is threadedly connected with the screw rod 35, and the two ends of the connecting arm 37 are rotatably connected with the sliding seat 32 and the screw seat 36 respectively, so that when the screw rod 35 rotates, the screw seat 36 can move along the axial direction of the screw rod 35, and the connecting arm 37 can push the sliding seat 32 to move along the axial direction of the guide rod 33. The second motor 34 is installed in the hot pressing table 10, and the output end of the second motor 34 is clamped and fixedly connected with the adjacent end of the screw rod 35, so that the second motor 34 can drive the screw rod 35 to rotate.

[0025] In the embodiment, one side or opposite sides of the sliding seat 32 and the screw seat 36 are formed with a convex column, and the set of connecting arms 37 comprises one or two connecting arms 37, and the connecting arm 37 is sleeved on the convex column and is rotatably connected with the convex column.

[0026] In the embodiment, the second limiting plate 31 can protrude out of the height of the second guide groove, and the thickness of the two second limiting plates 31 is smaller than the thickness of the plywood, so that interference with the hot pressing plate 11 can be avoided during the hot pressing process.

[0027] The system of the application can also comprise a control system for controlling the operation of the above-mentioned motors to automatically operate the plywood limiting and positioning. It should be understood that the control system is not particularly limited and can be realized by the control technology in the prior art, which will not be described here.

[0028] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape and principle of the application should be covered within the protection scope of the application.
