Description

Technical Field

[0001] The utility model belongs to the technical field of gypsum boards, and in particular relates to an ultra-thick gypsum board extrusion molding device. Background Art

[0002] Gypsum board is a material made primarily from building gypsum. It's lightweight, strong, thin, easy to process, and boasts excellent sound insulation, heat insulation, and fire resistance. It's one of the new lightweight board materials currently receiving significant development. Gypsum board is widely used in a variety of buildings, including residences, offices, shops, hotels, and industrial plants, for interior partitions, wall coverings (instead of wall plaster), ceilings, sound-absorbing panels, floor baseboards, and various decorative panels. However, it's not suitable for indoor installation in bathrooms or kitchens.

[0003] Currently, when producing gypsum board, gypsum slurry needs to be added to the paper panel, and then the paper panel and the gypsum slurry are laminated by a pressing roller. The pressed gypsum board is transported by a conveyor. During transportation, the gypsum board is easily shaken, causing folds at the edges or center of the gypsum board, and even cracks, which affects the use of the product. Utility Model Content

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1

[0022] The utility model provides an ultra-thick gypsum board extrusion molding device, such as Figures 1 to 5 As shown, it includes: a conveying device 1, a fixing frame 2 is fixedly installed on both sides of the conveying device 1, a pressure roller 3 is rotatably connected inside the fixing frame 2, a support frame 4 is fixedly installed on both sides of the conveying device 1, a first bearing 41 is symmetrically fixedly installed inside the support frame 4, a positive and negative screw rod 5 is connected between the inner rings of the two first bearings 41 through interference fit, the outer surfaces of the positive and negative screw rods 5 are symmetrically connected to the sliders 52 through threads, a rack 53 is slidably installed inside the two sliders 52, one end of the rack 53 is fixedly connected to the pressure block 54, the two sliders 52 are internally connected to the screw 55 through threads, and the screw The outer surface of the rod 55 is located at one end inside the slider 52 and is connected to the second bearing 56 through an interference fit. The outer ring of the second bearing 56 is fixedly connected to a clamping block 57. The clamping block 57 is slidably installed inside the slider 52. According to the gypsum boards of different thicknesses being processed, the height of the falling rack 53 is controlled, so that the pressure block 54 falls to a specific position, and then the screw 55 is rotated. Under the action of the second bearing 56, the clamping block 57 slides in the direction close to the rack 53, so that the raised part of the clamping block 57 is engaged with the gap position of the rack 53, and the pressure block 54 is fixed inside the slider 52.

[0023] like Figure 2 and Figure 4 As shown, a limiting rod 42 is fixedly installed between the inner walls of the support frame 4, and the two sliders 52 are both sleeved on the outer surface of the limiting rod 42. Through the setting of the limiting rod 42, when the forward and reverse screw rods 5 are rotated, the limiting rod 42 converts the rotation of the forward and reverse screw rods 5 into linear motion of the two sliders 52, while ensuring the movement trajectory of the two sliders 52 and improving the stability of the sliders 52 when moving.

[0024] like Figure 2 and Figure 3 As shown, a connecting rod 6 is symmetrically fixedly installed on one side of the support frame 4, and a fixed rod 61 is fixedly connected to the inside of the two connecting rods 6, and a movable rod 62 is threadedly connected to the inside of the two fixed rods 61. The ends of the two movable rods 62 away from the fixed rod 61 are rotatably connected to the cutting knife 63, and the outer surfaces of the two cutting knives 63 are fixedly connected to the guide plate 64. The bottom end surfaces of the cutting knife 63 and the guide plate 64 are both fitted to the top of the conveying device 1. Through the setting of the guide plate 64, the excess part of the gypsum board is cut by the cutting knife 63, and the excess cut part of the gypsum board is intercepted by the guide plate 64. Then the staff collects and reuses the intercepted gypsum board to reduce resource waste.

[0025] Working principle: When using this device, the staff rotates the handle 51 according to the specifications of the gypsum board required by the customer, so that it drives the forward and reverse screw rods 5 to rotate, and cooperates with the limit rod 42. The rotating forward and reverse screw rods 5 drive the two sliders 52 to make linear motion at the same time, and control the number of turns of the forward and reverse screw rods 5 to make the two sliders 52 located at specific positions. Then, the rack 53 is moved downward, and the pressing block 54 is driven downward. According to the thickness of the gypsum board to be produced, the bottom end surface of the pressing block 54 is made to fit the top surface of the gypsum board to prevent the gypsum board from shaking during the cutting process. The screw 55 is rotated to make the raised part of the block 57 engage with the gear The gap between the strips 53 is opened, and the pressing block 54 is fixed to the top of the gypsum board. Then, the movable rod 62 is rotated at the same time to drive the two cutting knives 63 to move toward the center of the conveyor belt. According to the gypsum board width required by the customer, the positions of the two cutting knives 63 are adjusted so that the two cutting knives 63 are in the same horizontal direction and the straight-line distance between the opposite surfaces of the two cutting knives 63 is equal to the width of the gypsum board, so that the excess part of the produced gypsum board is cut off. The excess gypsum board is intercepted on the surface of the conveyor belt by the guide plate 64, and then the staff collects and processes the excess gypsum board for reuse, thereby improving resource utilization.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
