DETAILED DESCRIPTION

[0038] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0039] See also Figure 1-4 As shown, the water squeezing device for gypsum processing comprises a processing box 1 and a conveyor belt 2, and a first opening and a second opening are respectively opened on both sides of the processing box 1;

[0040] The conveyor belt 2 enters from the first opening of the processing box 1 and passes through the second opening, thereby penetrating the processing box 1;

[0041] A limiting component 8 is installed on one side of the first opening in the processing box 1, and a calibration component 9 is installed on one side of the second opening in the processing box 1;

[0042] The top of the processing box 1 is provided with a first squeezing assembly 3, a driving frame 5 and a second squeezing assembly 4 in sequence along the moving direction of the gypsum.

[0043] In this embodiment, the driving frame 5 includes a fourth lifting cylinder, and a driving module is installed at the bottom of the fourth lifting cylinder, and the driving module is connected to the wheel frame 6;

[0044] During operation, the conveyor belt 2 drives the gypsum to pass through the first water squeezing assembly 3, the wheel frame 6 and the lower side of the second water squeezing assembly 4 in sequence.

[0045] When the gypsum passes through the first squeezing assembly 3, the first squeezing and dehydration is performed;

[0046] When the plaster passes through the wheel frame 6, the partition assembly 7 on the outside of the wheel frame 6 divides the plaster into multiple sections;

[0047] When the multiple sections of gypsum pass through the second squeezing assembly 4, a second squeezing and dehydration is performed;

[0048] Two groups of support components 10 are installed at the bottom end of the processing box 1. The two groups of support components 10 pass through the conveyor belt 2 and are respectively located at the lower sides of the first water squeezing component 3 and the second water squeezing component 4. When the first water squeezing component 3 and the second water squeezing component 4 contact the gypsum of the conveyor belt 2, the two groups of support components 10 respectively support the corresponding parts of the conveyor belt 2, thereby increasing the contact quality between the gypsum on the conveyor belt 2 and the first water squeezing component 3 or the second water squeezing component 4.

[0049] See also Figure 2 As shown, the first water squeezing assembly 3 and the second water squeezing assembly 4 both include a stroke cylinder 31, the stroke cylinder 31 is used to connect with the processing box 1, and the output end of the stroke cylinder 31 faces downward and is installed with a driving unit 32, and the output end of the driving unit 32 is installed with a squeezing roller 33;

[0050] Driven by the driving unit 32, the squeezing roller 33 contacts the gypsum on the conveyor belt 2 to squeeze water out of the gypsum.

[0051] The support assembly 10 includes a plurality of first lifting cylinders 101 , which are respectively arranged on both sides of the conveyor belt 2 , and the output end of each first lifting cylinder 101 faces upward, and a support platform 102 penetrating the conveyor belt 2 is installed between them.

[0052] See also Figure 3 As shown, the partition assembly 7 includes two sets of fixed plates 71, both sets of fixed plates 71 are connected to the wheel frame 6, and the two sets of fixed plates 71 are perpendicular to the moving direction of the conveyor belt 2;

[0053] Electromagnetic drive components 72 are installed on opposite sides of the two sets of fixed plates 71, and a movable plate 73 is installed between the output ends of the two sets of electromagnetic drive components 72;

[0054] When the two sets of electromagnetic drive components 72 are not started, the lower surface of the movable plate 73 and the lower surfaces of the two sets of fixed plates 71 are in the same horizontal direction;

[0055] After the two sets of electromagnetic drive components 72 are synchronously started, the movable plate 73 is driven to move along the moving direction of the conveyor belt 2 .

[0056] A plurality of sliding rollers 74 are installed inside the wheel frame 6 , and the top end of the movable plate 73 is slidably connected to each sliding roller 74 .

[0057] See also Figure 4 As shown, the calibration component 9 includes a connecting shell 91, a third lifting cylinder 92 is installed at the top of the connecting shell 91, the output end of the third lifting cylinder 92 faces downward, and a pressure sensing component 93 is installed;

[0058] A sliding frame 94 is slidably connected to the lower side of the pressure sensing component 93 in the connection shell 91, and a rotating roller 95 is rotatably connected to the bottom end of the sliding frame 94;

[0059] The sliding frame 94 includes a sliding section slidably connected to the connecting shell 91 , a connecting section connected to the rotating roller 95 is arranged at the lower side of the connecting section, and an elastic section is installed between the sliding section and the connecting section.

[0060] The limiting assembly 8 comprises a second lifting cylinder 81, the output end of the second lifting cylinder 81 faces downward and is provided with a scraper 82;

[0061] The scraper 82 changes its height based on the second lifting cylinder 81, thereby adjusting the distance between the bottom of the scraper 82 and the conveyor belt 2.

[0062] When the present invention is used:

[0063] The gypsum with a high water content is transported to the processing box 1 along the conveyor belt 2. When entering the processing box 1, the scraper 82 in the limiting component 8 limits the height of the gypsum to make the thickness of the gypsum uniform.

[0064] When the gypsum subsequently enters the lower side of the first squeezing assembly 3, the support assembly 10 at the lower side of the first squeezing assembly 3 is started to support the gypsum from the inside of the conveyor belt 2, and the squeezing roller 33 in the first squeezing assembly 3 performs the first squeezing operation on the gypsum;

[0065] Then the gypsum passes through the lower side of the wheel frame 6 along with the conveyor belt 2, and the wheel frame 6 rotates based on the driving frame 5, and the direction of rotation of the wheel frame 6 is the same as the moving direction of the conveyor belt 2;

[0066] When the partition assembly 7 on the outside of the wheel frame 6 contacts the plaster on the conveyor belt 2, the plaster on the front side of the partition assembly 7 is cut off from the plaster on the rear side. After the cutting, the two sets of electromagnetic drive assemblies 72 in the partition assembly 7 are started to slide the movable plate 73 along the sliding rollers 74, so as to process the gap between the plaster on the front side and the plaster on the rear side.

[0067] Then the gypsum moves to the lower side of the second squeezing assembly 4 based on the conveyor belt 2, and the second squeezing assembly 4 cooperates with the supporting assembly 10 at the lower side thereof to squeeze the gypsum for the second time, thereby reducing the moisture content of the gypsum again.

[0068] Finally, the gypsum passes through the lower side of the calibration component 9, and the sliding frame 94 is lifted up by the rotating roller 95 until the sliding frame 94 contacts the pressure sensing component 93. The pressure sensing component 93 generates corresponding readings based on the pressure to monitor the thickness of the gypsum after squeezing water on the conveyor belt 2.

However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
