Description

Technical Field

[0001] This application relates to the field of gypsum board production technology, and in particular to a manual correction device for gypsum board facing paper. Background Technology

[0002] In the gypsum board production process, facing paper is the main raw material, usually supplied in rolls and purchased from multiple manufacturers. Because facing paper is produced in rolls and needs to be purchased from multiple suppliers, different batches of facing paper vary in terms of thickness uniformity and tension stability. These differences can easily cause the facing paper to deviate during the roller conveyor process on the production line.

[0003] Although automatic correction devices are widely used in existing technologies for real-time correction, their range is limited. Once the deviation exceeds their adjustment range, they cannot be effectively corrected, leading to production interruption or product quality degradation. In this case, manual intervention is required for preliminary correction. However, existing manual interventions mostly lack specialized tools and rely on experience for adjustment, resulting in low efficiency and insufficient accuracy, which cannot meet the demand for efficient and accurate pre-correction. Summary of the Invention

[0004] This application provides a manual correction device for gypsum board facing paper, which intervenes in advance to manually and accurately supplement the correction device, in order to solve the problems of low efficiency and insufficient accuracy caused by the reliance on experience-based adjustments in existing manual correction methods.

[0005] This application provides a manual alignment device for gypsum board facing paper, comprising:

[0006] support;

[0007] The first correction roller has its first end connected to the bracket.

[0008] The first correction unit is mounted on the bracket and connected to the second end of the first correction roller. The first correction unit raises / lowers the second end of the first correction roller by rotating around its own axis.

[0009] Preferably, it further includes a second correction unit, which is disposed on the bracket. The first end of the first correction roller is connected to the bracket through the second correction unit. The second correction unit raises or lowers the first end of the first correction roller by rotating around its own axis.

[0010] Preferably, the first correction unit and the second correction unit have the same structure, including:

[0011] The support disc is fixedly mounted on the bracket;

[0012] The adjusting component is rotatably mounted on the bracket and is coaxially arranged with the supporting disc.

[0013] Preferably, the adjusting member is a rod-shaped structure or a disc-shaped structure.

[0014] Preferably, the first correction unit further includes an adjustment handle, which is connected to the adjustment member, wherein:

[0015] Angle values ​​are engraved on the support disc, and scale pointers are provided on the adjustment handle and / or adjustment component.

[0016] Preferably, the first correction unit further includes a limiting mechanism for limiting the relative position / angle between the adjusting member and the supporting disk.

[0017] Preferably, the support disc is provided with an auxiliary limiting part for cooperating with the limiting mechanism.

[0018] Preferably, the first correction roller is an elastic roller, and / or the first correction roller has elastic portions at both ends.

[0019] Preferably, the manual correction device further includes a second correction roller, which is parallel to the first correction roller, and the second correction roller has the same structure and material as the first correction roller.

[0020] Preferably, it also includes a sensor and a display device, wherein:

[0021] The sensor is an angle sensor, which is connected to the first correction unit and the display device respectively.

[0022] The display device is a digital angle display, which is located on the outside of the bracket and is used to display the rotation angle of the first correction unit.

[0023] The sensor is also connected to an alarm device to issue an alarm when the adjustment angle exceeds a preset threshold.

[0024] The beneficial effects of this application are as follows:

[0025] The manual correction device for gypsum board facing paper of this application achieves rapid adjustment and locking of the correction roller by adjusting the cooperation between the handle and the support disc. The lifting / lowering angle of the handle is quantified by the engraved angle value and the corresponding scale pointer, reducing the difficulty of operation. This device can intervene in advance to supplement the correction when the deviation of the facing paper has not reached the upper limit of the automatic correction device, so as to avoid the failure of the automatic correction device due to the deviation exceeding the limit, reduce the number of downtime adjustments, ensure production continuity, and reduce the scrap rate of the facing paper by manual pre-adjustment, thus extending the service life of the automatic correction device.

[0026] Furthermore, through the cooperation of auxiliary limiting parts, angle value markings, and scale pointers, the rotation angle of the adjustment parts can be precisely controlled, reducing the randomness of manual adjustment, thereby reducing the waste rate of facing paper and improving the quality stability of gypsum board products.

[0027] In particular, the sensor and display screen can provide real-time feedback on the adjusted angle, improving adjustment accuracy or prompting manual intervention to adjust the overall height. Attached Figure Description

[0033] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The following is combined Figure 1-2 This application describes the manual correction device for gypsum board facing paper provided in the embodiments of this application.

[0035] Reference Figure 1As shown in the embodiment of this application, the manual correction device for gypsum board facing paper includes a support 1, a first correction roller 4, a second correction roller 7, a first correction unit, and a second correction unit. The support 1 supports the entire device and its height is adjustable to adapt to different working conditions. The first and second correction units are symmetrically arranged on both sides of the support 1. The first and second correction units can raise / lower the first or second end of the corresponding two correction rollers by rotating around their own axes. Specifically, the support 1 includes a base 11 and a vertical rod. 12. Reinforcing ribs 13 and connecting plates 14, wherein there are two bases 11 and two vertical rods 12. The vertical rods 12 are vertically mounted on the bases 11. Two reinforcing ribs 13 are provided on both sides of any one of the vertical rods 12. The connecting plates 14 are fixedly mounted between the two bases 11. The vertical rods 12 are height-adjustable telescopic rods or hydraulic rods to adapt to production lines of different heights or to make overall fine adjustments to the height of one side of the device. The support disc 3 is fixedly mounted on the telescopic end of the vertical rods 12. The reinforcing ribs 13 are used to enhance the stability of the structure.

[0036] The first and second correction units have the same structure, both including a support disk 3 fixedly mounted on the bracket 1 and an adjustment member 2 rotatably mounted on the bracket 1. The adjustment member 2 is a rod-shaped structure or a disk structure, and the adjustment member 2 and the support disk 3 are coaxially mounted on the same side of the bracket 1. The support disk 3 is fixed to the inner side of the vertical rod 12 of the bracket 1, and the adjustment member 2 is rotatably mounted on the inner side of the support disk 3 through a limiting pin that passes through the center of the support disk 3. The first correction unit and / or the second correction unit also includes an adjustment handle 5, which is fixedly connected to the adjustment member 2. An angle value is engraved on the support disk 3, and the adjustment handle 5 and / or the adjustment member 2 are provided with a scale pointer. In this embodiment, the adjustment member 2 is a disk structure, and the adjustment handle 5 is fixed on the outer periphery of the disk-shaped adjustment member 2 to drive the adjustment member 2 to rotate around its center, thereby driving the first correction roller 4 and the second correction roller 7 mounted on it to rotate.

[0037] The first correction roller 4 and the second correction roller 7 are two parallel correction rollers. They can exist simultaneously or individually. When they exist simultaneously, the two correction rollers are parallel and rotatably / fixed on the adjusting member 2. The axes of the two correction rollers are perpendicular to the radial direction of the supporting disc 3. The face paper passes between the two correction rollers. The side away from the adjusting handle 5 is the input end of the face paper, and the side closer to the adjusting handle 5 is its output end. The two correction rollers are the same except for their different positions. They can both be elastic rollers and / or have elastic parts at both ends to meet the lifting or lowering requirements.

[0038] The first correction unit and / or the second correction unit also include a limiting mechanism 6 for limiting the relative position / angle between the adjusting member 2 and the support disk 3, and the support disk 3 is provided with an auxiliary limiting part for cooperating with the limiting mechanism 6.

[0039] Specifically, the limiting mechanism 6 is a pin, tightening block or tightening bolt, etc., which can fix the relative position of the adjusting part 2 and the supporting disc 3. The adjusting part 2 is provided with a positioning hole, and the supporting disc 3 is provided with a scale hole, arc groove and other auxiliary limiting parts for the limiting mechanism 6 to pass through or tighten. The supporting disc 3 is also provided with an angle value, and the adjusting handle 5 or the adjusting part 2 is also provided with a scale pointer to indicate the adjustment angle.

[0040] For example, when multiple scale holes are provided at the support disk 3, the scale holes are evenly distributed along the circumference of the support disk 3, and each scale hole is marked with an angle value, the angle value range is 0±45°. A diameter line parallel to the horizontal line of the support disk 3 is its zero scale line. The marking range of the scale holes below the zero scale line is 0 degrees to -45 degrees, and the marking range of the scale holes above the zero scale line is 0 degrees to 45 degrees. When the support disk 3 is provided with an arc groove, the angle value is marked on the side of the arc groove near the outer circumference of the support disk 3. The adjustment handle 5 is also provided with a scale pointer, which points to the angle value on the support disk 3 to visually display the rotation angle of the adjustment component 2.

[0041] When the limiting mechanism 6 is a pin, it can be inserted into the positioning hole after passing through the corresponding scale hole to fix the relative position between the adjusting part 2 and the supporting disc 3. When the limiting mechanism 6 is a tightening block or a tightening bolt, the corresponding bolt can be threaded through the positioning hole and the arc groove and then connected to the tightening block. By rotating the tightening block, the relative position between the adjusting part 2 and the supporting disc 3 can be locked and fixed. The arc groove structure can support its continuous adjustment and enhance its continuity. Alternatively, the tightening bolt can be directly threaded through the positioning hole with the corresponding thread and tightened and limited to the corresponding surface of the supporting disc 3. These will not be described in detail here.

[0042] During operation, the face sheet passes between the two correction rollers. When the face sheet deviates to one side, the operator can turn the adjustment handle 5 on that side, causing the adjustment component 2 and the correction roller mounted on it to rotate around the center of the support disc 3. This raises or lowers the height of the correction roller near the adjustment handle 5. This action changes the path of the face sheet, using gravity to gradually pull the paper tape back to this side or the other side, or to curb its tendency to deviate to this side or the other side, preventing it from exceeding the correction range of the automatic correction device. After adjusting to the appropriate angle, it can be locked with the limit mechanism 6.

[0043] By adjusting the coordination between the handle 5 and the support disc 3, the correction roller can be quickly adjusted and locked. The lifting / lowering angle of the handle 5 can be quantified by the engraved angle value and the corresponding scale pointer, reducing the difficulty of operation. This allows the device to intervene in advance to supplement the automatic correction device before the deviation of the face paper reaches the upper limit of the range, avoiding the failure of the automatic correction device due to the deviation exceeding the limit, reducing the number of downtime adjustments, ensuring production continuity, and reducing the scrap rate of the face paper through manual pre-adjustment, thus extending the service life of the automatic correction device.

[0044] As another embodiment of this application, please continue to refer to... Figure 2 ,like Figure 2 As shown, it is a schematic diagram of the overall structure of a manual correction device for gypsum board facing paper according to another embodiment of the present application.

[0045] Specifically, the main difference between this embodiment and the previous embodiment lies in the structure of the adjusting member 2. In this embodiment, the adjusting member 2 is a rod-shaped structure. Both the first and second correction units include a support disk 3 fixedly mounted on the bracket 1. One end of the adjusting handle 5 near the support disk 3 is fixedly connected to one end of the rod-shaped adjusting member 2. The rod-shaped adjusting member 2 is rotatably mounted on the inner side of the support disk 3 via a limiting pin that passes through the center of the support disk 3. Two correction rollers are arranged parallel to each other on the adjusting member 2, and the two correction rollers are symmetrically arranged on both sides of the limiting pin. This allows the two correction rollers mounted on the rod-shaped adjusting member 2 to rotate around the center of the support disk 3 under the drive of the adjusting handle 5, thereby raising or lowering accordingly. Its working principle is similar to that of the other embodiment. By rotating the adjusting handle 5, the adjusting member 2 and the correction rollers are rotated and raised or lowered to achieve correction.

[0046] In some specific embodiments, the end of the adjusting handle 5 away from the supporting disc 3 is provided with an anti-slip texture or an anti-slip rubber sleeve, and the surface of the anti-slip rubber sleeve is provided with a textured surface.

[0047] In some specific embodiments, to further improve the accuracy and intelligence of the operation, the correction device may also include sensors and a display device, wherein:

[0048] The sensor is an angle sensor, which is connected to a corresponding correction unit and a display device. Specifically, the angle sensor can be installed on the rotating shaft of the adjustment handle 5 or the adjustment component 2 to detect its rotation angle.

[0049] The display device is a digital angle display, which is set on the outside of the bracket 1 to intuitively display the current adjustment angle, so as to help the operator determine the adjusted angle of the correction roller on this side and determine whether the overall height of the bracket 1 on this side needs to be adjusted.

[0050] On the other hand, the sensor can also be connected to the corresponding alarm device. When the adjusted angle exceeds a certain threshold, an alarm will be triggered to remind the external operator to make a judgment on whether the overall height of the support 1 on this side needs to be adjusted. The threshold should be no less than 60% of the adjustable range marked on the support disc 3.
