The plurality of support rod assemblies 3 are arranged on both sides of the support leveling plate 2 and capable of adjusting the support force of the support leveling plate 2. Wherein, the leveling plate 2 is used to improve the flatness of the plate A, and the plate A is generally a gypsum board, and the present application takes the gypsum board as an example for detailed description.

[0027] The plurality of support rod assemblies 3 of the embodiment of the present application can adjust the support force of the leveling plate 2, so that the pressure of the leveling plate 2 on the plate A can be adjusted in time according to the actual initial setting time of the plate in production, thereby reducing the generation of plate thickness unevenness and bubble plate and other defective products, and improving the flatness and overall quality of the plate A. Adjusting the support force of the support leveling plate 2 can be manually adjusted by the operator, or automatically adjusted by the equipment.

[0028] As shown in Figure 2 The support rod assembly 3 comprises a support rod 31 mounted on the support frame 1 and capable of adjusting the height, a telescopic rod 32 sleeved with the support rod 31 and capable of telescoping, and an elastic element 33 supported on the support rod 31 and the telescopic rod 32. The support rod 31 is provided with a first positioning portion 310, the telescopic rod 32 is provided with a second positioning portion 320, and the two ends of the elastic element 33 are supported on the first positioning portion 310 and the second positioning portion 320.

[0029] When the leveling plate 2 is supported on the support rod assembly 3, the support rod assembly 3 has a downward pressure, if the support rod 31 is raised, the support rod 31 presses the elastic element 33 through the second positioning 310, the elastic element 33 presses the telescopic rod 32 through the second positioning portion 320, the support force of the telescopic rod 32 on the leveling plate 2 is increased, thereby reducing the pressure of the leveling plate 2, and adjusting the pressure of the leveling plate 2 on the plate A.

[0030] In the embodiment of the present application, the support rod 31 can be an electric push rod, which can be automatically raised and lowered, for example, driven by a motor to automatically raise and lower. Of course, the support rod 31 can also be adjusted by manual, for example, a threaded screw connected with the support frame 1 is arranged, and the height of the support rod 31 is adjusted by manual rotation.

[0031] In one example embodiment, the support rod 31 can be a hydraulic rod, and by controlling the hydraulic pressure of the support rod 31, the pressure of the leveling plate 2 on the plate A is adjusted.

[0032] As shown in Figure 2 The telescopic rod 32 comprises a base rod, the base rod has opposite first and second ends, the first end is sleeved with the support rod 31, and the second end is provided with a first support head 321 capable of supporting the bottom end of the leveling plate 2, and the first support head 321 forms a second positioning end.

[0033] In the embodiment of the present application, the first support head 321 is a bull-eye bearing, which can support the leveling plate 2 in a universal manner, and can ensure timely adjustment of the position according to the transverse displacement of the plate material, so that the leveling plate 2 has a transverse flexible displacement relative to the first support head 321.

[0034] In the embodiment of the present application, the elastic element 33 is a compression spring, and the lifting of the support rod 31 can compress and relax the compression spring, thereby increasing or reducing the support force of the first support head 321 on the leveling plate 2.

[0035] As shown in Figure 1 , Figure 2 , the plate leveling device 100 further includes a plurality of push rod assemblies 4 arranged on the support frame 1 and capable of abutting against the side ends of the leveling plate 2. The push rod assemblies 4 extend in the opposite direction of the plate material conveying direction and can stop the side ends of the support leveling plate 2. The push rod assembly 4 includes a push rod 40, one end of which is mounted on the support frame 1, and the other end of which is provided with a second support head 41. The push rod 40 is connected to the support frame 1 in a detachable manner, for example, by the threads of the push rod 40 and the nuts 42. The push rod assembly 4 includes a plurality of push rods, which can be arranged on both sides of the side ends of the leveling plate 2.

[0036] In the embodiment of the present application, the second support head 41 is a bull-eye bearing, which can ensure timely adjustment of the position according to the longitudinal displacement of the plate material A, and can cooperate with the side section of the leveling plate 2 to enable the leveling plate 2 to have a longitudinal flexible displacement relative to the second support head 41.

[0037] As shown in Figure 1 , Figure 2 , the plate leveling device 100 further includes a lifting device 5 mounted on the support frame 1, which includes a first state capable of lifting the leveling plate 2 away from the support rod assembly 3 and a second state away from the leveling plate 2.

[0038] In the embodiment of the present application, the lifting device 5 can be a pneumatic cylinder device, which includes a plurality of devices arranged on both sides of the bottom end of the leveling plate 2. When the lifting device 5 is raised, the leveling plate 2 can be lifted; when the lifting device 5 is lowered, the leveling plate 2 can be separated from the leveling plate 2, and the leveling plate 2 is placed on the support assembly 3 to level the plate material A. Generally, when the plate material A production is stopped or fails, the lifting device 5 is needed to lift the leveling plate 2, and when it is in normal working condition, the lifting device 5 is lowered, which does not interfere with the work of the leveling plate 2.

[0039] As shown in Figure 2 , the plate leveling device 100 of the embodiment of the present application further includes a leveling plate 2 supported on the support rod assembly 3. The leveling plate 2 includes a bottom plate 21 and a side plate 22 extending upward from the side of the bottom plate 21.

[0040] In this embodiment, the leveling plate 2 is in the shape of a U-section, and the side plates 22 include two oppositely arranged side plates. The support rod assembly 3 is supported on the bottom plate 21 of the leveling plate 2, and the push rod assembly 4 pushes against the side plates 22 of the leveling plate 2. When the plate material is running, the plate material will have a driving force in the transverse and longitudinal directions on the leveling plate 2. The bull-eye bearing of the support rod assembly 3 can prevent the support rod assembly 3 from being hard connected to the leveling plate 2, which can cause damage to the surface of the plate material. The push rod assembly 4 can prevent the plate material A from moving the leveling plate 2, and can also allow the leveling plate 2 to have a certain longitudinal flexible displacement, which can prevent hard connection from causing damage to the surface of the plate material. As shown in Figure 1 The plate leveling device 100 of the embodiment of the present application also provides a plate leveling equipment, which includes a plate conveying device 6 and the plate leveling device 100 as described in any of the above embodiments arranged on the plate conveying device 6. The plate conveying device 6 includes a conveying frame 60, a plurality of conveying rollers 61 mounted on the conveying frame 60, and a belt 62 for driving the plurality of conveying rollers 61 to rotate. The support frame 1 of the plate leveling device 100 is arranged on the conveying frame 60, and the plurality of support rod assemblies 3 of the plate leveling device 100 are arranged on both sides of the conveying frame 60.

[0041] In normal production of the plate leveling equipment of the embodiment of the present application, the plate material A is leveled by the leveling plate 2 (the running direction of the plate material is as shown in Figure 1 The surface of the plate material A is leveled, the leveling plate 2 falls and contacts the gypsum board, and the lower portions of the two side plates of the leveling plate 2 are supported by the support assembly 3. When it is necessary to adjust the pressure of the leveling plate 2 on the plate material, the compression or relaxation of the elastic element 33 of the support assembly 3 is adjusted, so as to increase or decrease the support force on the leveling plate 2, so as to adjust the pressure of the leveling plate 2 on the plate material. When the production is unstable and needs to be adjusted, the lifting device 5 lifts the leveling plate 2.

[0042] The plate leveling device 100 of the embodiment of the present application also includes a motor (not shown) connected to the support assembly 3 and a controller (not shown) for controlling the operation of the motor. The motor can drive the support rod 31 of the support assembly 3 to lift. Since the parameters such as the setting time of the plate material A are tracked and monitored in real time during the production process, when these parameters change, the controller will automatically control the push rod to take the action of elongation or shortening. In this way, the force between the push rod and the bull-eye bearing will change, and the force of the compression spring 33 is entirely used to support the leveling plate 2. Therefore, the pressure of the leveling plate 2 on the plate material is the gravity of the leveling plate minus the elastic force of the spring. Therefore, according to this mode, the pressure of the leveling plate 2 on the plate material can be calculated and controlled by a program, and the corresponding parameters are input into the system in real time for automatic adjustment. The bull-eye bearing has a universal ball to support the leveling plate 2, which can ensure that the position is adjusted in real time with the transverse displacement of the plate material.

[0043] The plate flattening device 100 of the embodiment of the present application greatly reduces the work intensity of the post staff, and timely adjusts the pressure of the flattening plate 2 on the plate according to the actual situation in production. In addition, the plate flattening device 100 of the embodiment of the present application improves the degree of automation of the equipment, reduces the generation of plate thickness unevenness and bubble plate and other defective products, and improves the plate flatness 2 and overall quality.
