Description

Technical Field

[0001] The present application relates to the technical field of paper rectifying devices, and more specifically, to a paper rectifying device, a paper loading device, and a gypsum board production line. Background Art

[0002] Gypsum boards are provided with an upper facing paper and a lower facing paper. A gypsum board production line is provided with a paper loading device for performing a paper loading operation on the gypsum board. During the process of transporting the paper, there may be a situation where the paper deviates from the set conveying route, that is, the paper runs off track. Therefore, a rectifier needs to be provided in the paper loading device to correct the problem of the paper running off track.

[0003] For traditional rectifiers, due to the travel limit of the movable bracket, the maximum rectifying range of the rectifier for the paper is limited. Especially during the paper loading operation, due to the uncertainty of manual operation, the error between the actual conveying route of the paper and the preset conveying route may far exceed the adjustment range of the rectifier. At this time, it is necessary to temporarily stop the machine and manually intervene to adjust the position of the base paper rack. After manually adjusting the position of the base paper rack, the machine is restarted to convey the paper, which greatly reduces the production efficiency. Summary of the Utility Model

[0004] The embodiments of the present application provide a paper rectifying device, a paper loading device, and a gypsum board production line. The paper rectifying device of the present application is provided with a first detection component and a base paper rack adjustment component. When the first detection component detects that the movable bracket of the rectifier reaches the rectifying limit position, the base paper rack adjustment component can drive the base paper rack to move along the width direction of the paper. In this way, when the actual position of the paper exceeds the adjustment range of the rectifier, the conveying route of the paper can also be adjusted mechanically and the paper conveying action can be performed without stopping the machine and manually adjusting the position of the base paper rack, thereby improving the production efficiency.

[0005] The technical solution of the embodiments of the present application is as follows:

[0006] A paper rectifying device, comprising:

[0007] A base paper rack adjustment component, configured to be able to drive a base paper rack for storing and outputting paper to move along the width direction of the paper, so as to adjust the conveying route of the paper;

[0008] A rectifier, located on the downstream side of the base paper rack along the paper conveying direction, comprising a movable bracket for supporting the paper, and the movable bracket can move along the width direction of the paper to perform a rectifying process on the paper; and

[0009] A first detection component, installed on the rectifier, configured to detect whether the movable bracket reaches the rectifying limit position;

[0010] When the first detection component detects that the movable bracket reaches the deviation correction limit position, the base paper rack adjustment component drives the base paper rack to move along the width direction of the paper so as to adjust the paper position.

[0011] A paper loading device includes the paper deviation correction device and the base paper rack as described in the above embodiment, and the base paper rack is located on the upstream side of the paper deviation correction device along the paper conveying direction.

[0012] A gypsum board production line includes the paper loading device as described in the above embodiment.

[0013] The technical effects of the paper deviation correction device in the embodiments of the present application are as follows:

[0014] In the paper deviation correction device of the embodiments of the present application, when the first detection component detects that the movable bracket of the deviation corrector reaches the deviation correction limit position, that is, when the actual conveying route of the paper deviates from the set conveying route by a large amount and has exceeded the deviation correction range of the deviation corrector, the base paper rack adjustment component drives the base paper rack to move along the width direction of the paper so as to adjust the paper position. In this way, even if the actual conveying route of the paper exceeds the deviation correction range of the deviation corrector, the paper can be mechanically corrected and the paper conveying operation can be performed without stopping the machine for processing and manually adjusting the position of the base paper rack, thereby expanding the deviation correction range of the paper, improving the production efficiency, reducing the labor cost, and greatly enhancing the stability and reliability of the paper product.

[0021] To make the objectives, technical solutions and advantages of the present application more clearly understood, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0022] Please refer to Figures 1 to 4 the structural schematic diagram of the paper deviation rectifying device according to the embodiment of the present application as shown. Figure 1 and Figure 3 the arrow direction in

[0023] As Figures 1 to 2 shown, the paper deviation rectifying device provided by the embodiment of the present application includes a raw paper rack adjusting component 1, a deviation rectifier 2 and a first detection component 5. Among them, the raw paper rack adjusting component 1 is configured to be able to drive the raw paper rack 3 for storing and outputting the paper 4 to move along the width direction of the paper 4, so as to adjust the conveying route of the paper 4. The deviation rectifier 2 is located on the downstream side of the raw paper rack 3 along the conveying direction of the paper 4, and includes a movable bracket 21 for supporting the paper 4. The movable bracket 21 can move along the width direction of the paper 4 to perform deviation rectifying processing on the paper 4. The first detection component 5 is installed on the deviation rectifier 2 and is configured to detect whether the movable bracket 21 reaches the deviation rectifying limit position. When the first detection component 5 detects that the movable bracket 21 reaches the deviation rectifying limit position, the raw paper rack adjusting component 1 drives the raw paper rack 3 to move along the width direction of the paper 4 so as to adjust the position of the paper 4.

[0024] Specifically, the working content of the paper deviation rectifying device according to the embodiment of the present application is as follows: when the first detection component 5 does not detect that the movable bracket 21 reaches the deviation rectifying limit position, the deviation rectifier 2 performs the deviation rectifying operation on the paper 4, that is, the movable bracket 21 of the deviation rectifier 2 moves along the width direction of the paper 4, so as to drive the paper 4 to move along the width direction of the paper 4 together, thereby performing a deviation rectifying action on the paper 4. The deviation rectifier 2 has the advantages of high sensitivity and timely deviation rectifying reaction. When the first detection component 5 detects that the movable bracket 21 of the deviation rectifier 2 reaches the deviation rectifying limit position, that is, when the actual conveying route of the paper 4 deviates from the set conveying route by a large amount and has exceeded the deviation rectifying range of the deviation rectifier 2, the raw paper rack adjusting component 1 drives the raw paper rack 3 to move along the width direction of the paper 4 so as to adjust the position of the paper 4. In this way, even if the actual conveying route of the paper 4 exceeds the deviation rectifying range of the deviation rectifier 2, the deviation rectifying operation on the paper 4 and the paper 4 conveying operation can be mechanized, without stopping the machine for processing and manually adjusting the position of the raw paper rack 3, thereby improving the production efficiency, reducing the labor cost, and at the same time greatly improving the product stability and reliability of the paper 4.

[0025] It should be noted that, as Figure 1As shown in the figure, in the embodiment of the present application, a control component 6 can be provided. The control component 6 is electrically connected to the raw paper rack adjusting component 1, the deviation rectifier 2, and the first detection component 5, and is used to control the working process of the paper deviation rectifying device.

[0026] In an exemplary embodiment, as Figure 1 and Figure 2 shown, the deviation rectifier 2 further includes a fixed bracket 22, a roller 23, and a driving device. Among them, the movable bracket 21 is movably mounted to the fixed bracket 22. The roller 23 is mounted to the movable bracket 21, and the roller 23 is arranged to convey the paper 4. The driving device 24 is connected to the movable bracket 21 and is arranged to be able to drive the movable bracket 21 to move along the width direction of the paper 4, so as to adjust the conveying route of the paper 4. The first detection component 5 is arranged to: detect the position change of the movable bracket 21 relative to the fixed bracket 22.

[0027] Specifically, the deviation rectifier 2 has a mature product, which will not be elaborated here. The movable bracket 21 of the deviation rectifier 2 can reciprocally move along the width direction of the paper 4 within the range delimited by the deviation rectifying limit positions, so as to perform a deviation rectifying operation on the paper 4. The fixed bracket 22 is fixedly arranged. The first detection component 5 obtains whether the movable bracket 21 reaches the deviation rectifying limit position by detecting the position change of the movable bracket 21 relative to the fixed bracket 22.

[0028] In an exemplary embodiment, as Figure 2 and Figure 3 shown, the first detection component 5 includes a proximity switch. The proximity switch is located on at least one side of the movable bracket 21 along the width direction of the paper 4 and is arranged to detect the position of the side portion 211 of the movable bracket 21 along the width direction of the paper 4.

[0029] Specifically, the proximity switch has a simple structure and is easy to install and maintain. As Figure 3 shown, in the embodiment of the present application, a proximity switch can be provided on one side or both sides of the movable bracket 21 along the width direction of the paper 4, and the proximity switch is used to measure whether the side portion 211 of the movable bracket 21 reaches the deviation rectifying limit position.

[0030] In an exemplary embodiment, as Figure 3 shown, the proximity switch is an inductive proximity switch and includes a proximity sensor 51 mounted to the fixed bracket 22 and an inductive fitting 52 mounted to the side portion 211 of the movable bracket 21. The proximity sensor 51 and the inductive fitting 52 cooperate to work.

[0031] Specifically, the inductive proximity switch has the advantages of convenient installation and operation, high sensitivity, and anti-interference. When the induction fitting 52 moves to the deviation correction limit position together with the movable bracket 21, the proximity sensor 51 generates a signal and sends the signal to the control component 6 so that the paper reel adjusting component 1 performs the deviation correction operation on the paper 4.

[0032] In an exemplary embodiment, as Figure 2 and Figure 3 shown, the driving device 24 includes a motor 241 and a linear bearing 242. The axial direction of the linear bearing 242 is inclined relative to the width direction of the paper 4, and the motor 241 is arranged to drive the movable bracket 21 to move through the linear bearing 242.

[0033] As Figure 3 shown, the movable bracket 21 includes a frame member 212. Rollers 23 are provided at both ends of the frame member 212 along the conveying direction of the paper 4, and linear bearings 242 are provided at each corner of the frame member 212.

[0034] Specifically, the axial direction of the linear bearing 242 is inclined relative to the width direction of the paper 4, so that the actual movement direction of the movable bracket 21 during the deviation correction operation is set at an angle with the width direction of the paper 4, which can avoid the slipping of the paper 4 with the roller 23 during the deviation correction process, thereby improving the stability and reliability of the paper deviation correction device. Rollers 23 are provided at both ends of the frame member 212 along the conveying direction of the paper 4, and linear bearings 242 are provided at each corner of the frame member 212, which can improve the stability of the deviation corrector 2 during the deviation correction operation.

[0036] Specifically, the first detection components 5 are arranged on both sides of the movable bracket 21 along the width direction of the paper 4, which can improve the detection sensitivity of the first detection components 5.

[0037] In an exemplary embodiment, as Figure 1 shown, the paper reel adjusting component 1 includes a hydraulic driving member 11 and an adjusting shaft 12. The adjusting shaft 12 is installed on the paper reel 3, and the hydraulic driving member 11 is connected to the adjusting shaft 12. The hydraulic driving member 11 is arranged to be able to drive the paper reel 3 to move along the width direction of the paper 4 through the adjusting shaft 12.

[0038] Specifically, the base paper rack 3 is used for storing and conveying the paper 4. The wound paper 4 is stored in the base paper rack 3. The base paper rack 3 is relatively heavy, and a hydraulic driving member 11 can be adopted to drive the base paper rack 11 to move. Optionally, the hydraulic driving member 11 is configured as a hydraulic workstation.

The second detection assembly 25 is disposed on the downstream side of the movable bracket 21 along the paper conveying direction and detects the position of the paper 4.

[0040] The driving device 24 is configured such that when the second detection assembly 25 detects that the position of the paper 4 deviates from the preset position, the driving device 24 drives the movable bracket 21 to move along the width direction of the paper 4 to correct the deviation of the paper 4.

[0041] In an exemplary embodiment, as Figure 2 and Figure 4 shown, the second detection assembly 25 includes a support member 251 and a photoelectric induction assembly 252. The support member 251 is mounted to the fixed bracket 22, and the photoelectric induction assembly 252 is mounted to the support member 251.

[0042] The photoelectric induction assembly 252 includes a transmitting portion 2521 and a receiving portion 2522. The transmitting portion 2521 and the receiving portion 2522 are respectively disposed on both sides of the paper 4 in the thickness direction.
