Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board equipment, and more specifically, to a gypsum board thickness monitoring device and a control method thereof. Background Art

[0002] In the process of producing gypsum board, changes in factors such as extrusion board, foaming, gypsum, etc. will cause the actual thickness of the gypsum board to change at different locations. The allowable deviation of the actual thickness of the gypsum board is usually within the range of ±0.5mm. That is, if the standard thickness of the gypsum board is 12mm, the actual thickness of the gypsum board is allowed to be between 11.5mm and 12.5mm, and the actual thickness of the gypsum board within this range is acceptable. This allowable deviation range ensures the consistency and stability of the gypsum board during installation and use.

[0003] Currently, the actual thickness of the gypsum board being transported is measured manually by the operator at a set time interval. If the actual thickness of the gypsum board measured is not up to standard, the operator makes corresponding adjustments to adjust the actual thickness of the gypsum board being produced to within the allowable range of the actual thickness. This solution is greatly affected by human factors. If the actual thickness of the gypsum board being produced is not up to standard, it is difficult for the operator to find out in time.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0020] The gypsum board thickness monitoring device provided by the embodiment of the present invention is as follows: Figure 1As shown, it includes: a conveying mechanism 100, which is configured to convey the gypsum board 10 from its conveying area 110 to the downstream; a first distance detection mechanism 200, which is located above the conveying area 110, and the first distance detection mechanism 200 is configured to detect the distance a between the first distance detection mechanism 200 and the upper side of the gypsum board 10; a second distance detection mechanism 300, which is located below the conveying area 110 and is correspondingly arranged with the first distance detection mechanism 200 in the upper and lower directions, and the second distance detection mechanism 300 is configured to detect the distance b between the second distance detection mechanism 300 and the lower side of the gypsum board 10; and a control unit, which is electrically connected to the first distance detection mechanism 200 and the second distance detection mechanism 300, and the control unit is configured to determine whether the actual thickness of the gypsum board 10 is qualified according to a, b, c and d; wherein c is the distance between the first distance detection mechanism 200 and the second distance detection mechanism 300, and d is the preset thickness range of the gypsum board 10.

[0021] The gypsum board thickness monitoring device, the gypsum board 10 is conveyed downstream in the conveying area 110 of the conveying mechanism 100, the first distance detection mechanism 200 detects the distance a between the first distance detection mechanism 200 and the upper side of the gypsum board 10, the second distance detection mechanism 300 is configured to detect the distance b between the second distance detection mechanism 300 and the lower side of the gypsum board 10, and the control unit is configured to determine whether the actual thickness of the gypsum board 10 (that is, the actual thickness of the gypsum board 10 at the position between the first distance detection mechanism 200 and the second distance detection mechanism 300) is qualified based on a, b, c and d. If the actual thickness of the gypsum board 10 being conveyed is unqualified, this solution can be discovered in time.

[0022] In some examples, the gypsum board thickness monitoring device further includes: an alarm mechanism, which is electrically connected to the control unit, and is configured to output an alarm message when the actual thickness of the gypsum board 10 is determined to be unqualified, so that the operator can be informed in time according to the alarm message, and thus make corresponding adjustments in time, and adjust the actual thickness of the produced gypsum board 10 to within the allowable range of the actual thickness in time, so as to avoid continuing to produce gypsum boards 10 with unqualified actual thickness. The alarm mechanism may be a speaker or a prompt light, etc.

[0023] In some examples, the gypsum board thickness monitoring device further includes: a storage mechanism (not shown in the figure), the storage mechanism is electrically connected to the control unit, the storage mechanism is configured to store the actual thickness e of the gypsum board 10, e=cab; and a display mechanism (not shown in the figure), the display mechanism is electrically connected to the control unit, and the display mechanism is configured to display the actual thickness e of the gypsum board 10 stored in the storage mechanism. When the actual thickness of the gypsum board 10 is unqualified, the operator makes corresponding adjustments in time according to the displayed actual thickness e of the gypsum board 10, so that the actual thickness of the produced gypsum board 10 can be adjusted to the actual thickness allowable range more quickly, and this solution can further reduce the length of the unqualified gypsum board 10 produced.

[0024] In some examples, such as Figure 1 As shown, the gypsum board thickness monitoring device also includes: a displacement detection mechanism 400, the displacement detection mechanism 400 is electrically connected to the control unit, the displacement detection mechanism 400 is configured to detect the length f of the gypsum board 10 conveyed, and the control unit is further configured to obtain a and b in sequence at the same time according to f at a set distance interval g, and then each group of a and b determines whether the actual thickness of the gypsum board 10 is qualified according to c and d.

[0025] It can be that the storage mechanism is configured to store the latest actual thickness e of the M groups of gypsum boards 10 in sequence, and the display mechanism is configured to display the latest actual thickness e of the M groups of gypsum boards 10 in sequence, and M can be 2 or 3 or 5 or 8 or 10 or 16, etc., all of which can achieve the purpose of this application, and its purpose does not deviate from the design idea of ​​the present invention, and will not be repeated here. The military camp falls within the protection scope of this application.

[0026] In some examples, such as Figure 1 As shown, the displacement detection mechanism 400 is an encoder, the transmission mechanism 100 is a conveyor belt mechanism, and the roller of the encoder abuts against the conveyor belt of the conveyor belt mechanism and rotates synchronously.

Then, the actual thickness e of each group of gypsum boards 10 stored in the storage mechanism includes N pieces.

[0028] In one embodiment, the standard thickness of the gypsum board 10 is set to 12 mm, the range of d is set to 11.7 mm to 12.3 mm, c is set to 50 mm, the width of the gypsum board 10 is set to 1200 mm, N is set to 13, and g is set to 100 mm (i.e., the actual thickness e of the gypsum board 10 at the position between the first distance detection mechanism 200 and the second distance detection mechanism 300 is detected once each time the gypsum board 10 moves 100 mm downstream). The detection accuracy of the photoelectric distance sensor is set to 0.01 mm to 0.04 mm.

[0029] The control method of the gypsum board thickness monitoring device provided by the embodiment of the present invention is as follows: Figure 2 As shown, including: Obtain a and b, and determine whether the actual thickness of the gypsum board 10 is qualified according to a, b, c and d; Wherein, c is the distance between the first distance detection mechanism 200 and the second distance detection mechanism 300 , and d is the preset thickness range of the gypsum board 10 .

[0030] The control method of the gypsum board thickness monitoring device can timely discover if the actual thickness of the gypsum board 10 being conveyed is unqualified.

[0032] In some examples, such as Figure 3 As shown, the control method further includes: obtaining f, and according to f, obtaining a and b in sequence at the same time with a set distance interval g, and then determining whether the actual thickness of the gypsum board 10 is qualified for each group of a and b according to c and d.
