Description

Technical Field

[0001] This application relates to equipment for producing paper-faced gypsum board, and more particularly to printing equipment for gypsum board facing paper. Background Technology

[0002] Paper-faced gypsum board is a type of board made primarily from building gypsum, with appropriate additives and fibers added to form the core, and a specially made paper surface. It is characterized by its lightweight, sound insulation, heat insulation, strong processing performance, and simple construction methods.

[0003] Typically, facing paper is stored in rolls. In the continuous production of gypsum board, the rolls of upper and lower facing paper are unrolled and flattened, then laid on top of the gypsum slurry to form a sandwich structure. Usually, the manufacturer and product information are also printed on the upper facing paper.

[0004] Continuous printing of the cover paper is accomplished by a printing assembly. The printing assembly typically includes a support roller and a printing roller that cooperate with each other. The support roller supports the paper surface to provide a printing support, while the printing roller prints the pattern or text onto the cover paper on the printing support. Therefore, the support roller and the printing roller need to operate synchronously. Typically, the support roller has a support roller gear at one end, and the corresponding end of the printing roller has a printing roller gear; these gears mesh with each other. The support roller is also connected to a drive mechanism, such as a drive belt. The drive belt drives the support roller to rotate, which in turn drives the printing roller to rotate via the meshing gears. Utility Model Content

[0005] The purpose of this application is to provide a gypsum board facing paper printing device using dual-roller printing.

[0006] Therefore, according to one aspect of this application, a gypsum board facing paper printing device includes a printing assembly, the printing assembly including a support roller and a printing roller, the support roller being provided with a support roller gear, the printing roller being provided with a printing roller gear, the support roller gear meshing with the printing roller gear, wherein a clutch is provided between the support roller gear and the support roller.

[0007] The first rotating part of the clutch is fixedly connected to the shaft of the support roller.

[0008] The second rotating part of the clutch is fixed to the shaft hole of the support roller gear.

[0009] Furthermore, the gypsum board facing paper printing equipment includes a first printing component and a second printing component, which are arranged along the traveling direction of the facing paper.

[0010] The gypsum board facing paper printing equipment also includes a first drying device, which is located downstream of the first printing component.

[0011] The gypsum board facing paper printing equipment also includes a second drying device and a third drying device, which are located downstream of the second printing component.

[0012] According to another aspect of this application, a gypsum board production equipment includes the aforementioned gypsum board facing paper printing equipment.

[0013] The technical solution of this application can realize dual-station printing, and can flexibly replace printing rollers, thereby realizing the replacement of printing rollers without stopping the machine, and can extend the service life of printing rollers. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of a printing apparatus according to an embodiment of the present application after installation on a gypsum board production line. Detailed Implementation

[0015] The specific embodiments of this application are described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, the facing paper 10 is guided into the gypsum board facing paper printing equipment 20 by the traction mechanism and the tension mechanism. Figure 1 The arrows shown indicate the conveying direction of the face sheet. Multiple idler wheels 30 are provided along the path of the face sheet 10.

[0017] In this application, the direction consistent with the direction of travel of the face paper is defined as the downstream direction, and the direction opposite to the direction of travel of the face paper is defined as the upstream direction. The terms "upstream" and "downstream" define the relative position of a component with respect to other components in the direction of travel of the face paper.

[0018] In the illustrated embodiment, the gypsum board facing paper printing equipment 20 includes a first printing assembly 200 and a second printing assembly 300. The first printing assembly 200 and the second printing assembly 300 are arranged along the travel path of the facing paper 10. Figure 1 In one embodiment, the first printing component 200 is arranged relatively upstream, and the second printing component 300 is arranged relatively downstream.

[0019] Both the first printing assembly 200 and the second printing assembly 300 are fixed to the frame 100. The first printing assembly and the second printing assembly have the same structure.

[0020] Each printing assembly includes an assembly mounting frame, a guide rail (not shown) fixed to the assembly mounting frame, a printing roller support movable on the guide rail, a printing roller with its shaft end connected to the printing roller support, and a support roller fixed to the frame 100. The support roller is equipped with a support roller gear, and the printing roller is equipped with a printing roller gear. During the printing of the face paper, the support roller gear and the printing roller gear can mesh with each other, thereby allowing the support roller to drive the printing roller to rotate.

[0021] The support roller gear is coupled to the support roller's shaft via a clutch, such as a multi-plate electromagnetic clutch. The clutch has a first rotating part and a second rotating part that can be coupled and fixed or disengaged from each other. The first rotating part is fixedly connected to the support roller's shaft, and the second rotating part is fixedly connected to the support roller gear. When the clutch plates are engaged, the first and second rotating parts rotate synchronously. When the clutch plates are disengaged, the first rotating part continues to rotate with the support roller's shaft, while the second rotating part idles due to inertia and eventually stops rotating under friction. When the clutch is disengaged, the support roller gear also idles due to the second rotating part's idling, allowing the support roller gear and the printing roller gear to disengage easily. This allows the printing roller to be easily moved away from the printing position from the cover paper 10, thus stopping printing, and the printing roller can be replaced as needed.

[0022] The drive mechanism (not shown in the figure) is coupled to the support roller to drive the support roller to rotate, thereby providing a driving force for the movement of the cover paper by means of friction, and providing a support for printing the cover paper.

[0023] Specifically, taking the first printing component 200 as an example, the first support roller 210 is fixed to the frame 100, and its position can be determined according to the specific application, as long as it corresponds to and couples with the position of the first printing roller 220. The first component fixing frame 230 is fixed to the frame 100, and the first guide rail is fixed on the first component fixing frame 210. The first printing roller support 220 can move along the first guide rail to get closer to or away from the cover paper 10, that is, closer to or away from the support roller 210.

[0024] The drive mechanism can be coupled to the first support roller 210 via a transmission belt to drive the first support roller 210 to rotate. The shaft of the first support roller 210 is provided with a first support roller gear (not shown in the figure), and the shaft of the first printing roller 220 is provided with a first printing roller gear (not shown in the figure). The first support roller gear and the first printing roller gear mesh.

[0025] A clutch (not shown in the figure) is provided between the first support roller gear and the shaft of the first support roller 210. The clutch has a first rotating part and a second rotating part, which are engaged or disengaged by clutch plates. The first transmission part is fixedly connected to the shaft of the first support roller, and the second transmission part is fixedly connected to the first support roller gear. As mentioned above, when the clutch is locked, a rigid connection is formed between the first support roller gear and the shaft of the first support roller, thereby causing them to rotate synchronously. At this time, through the meshing of the gears, the first support roller gear can drive the first printing roller gear to rotate, thereby driving the first printing roller to rotate.

[0026] By incorporating a clutch, the printing roller can be disconnected from or engaged with the drive mechanism, allowing the printing roller to be replaced as needed without stopping the machine.

[0027] According to an embodiment of this application, the printing apparatus 20 further includes a plurality of drying devices arranged close to the cover paper 10. Specifically, a first drying device 410 is located downstream of the first printing assembly, and a second drying device 420 and a third drying device 430 are located downstream of the second printing assembly.

[0028] The above description illustrates the details of the technical solution of this application. However, those skilled in the art will understand that this application is not limited to the specific details listed in the above embodiments, but can vary within the scope defined by the claims.
