As shown in figure 1, the invention provides an online sampling detection device and a detection method for a gypsum board production line, most of the existing gypsum board online sampling devices utilize a pushing cylinder to jack up a sampled gypsum board, then utilize a side pushing cylinder to transfer the sampled gypsum board to a detection mechanism for quality parameter measurement, because the sampled gypsum board is not dried after being cut, the existing side pushing cylinder transfers the sampled gypsum board in a flat pushing mode, because the friction force on the gypsum board is large in the transmission process of the sampled gypsum board at the moment, the force application of the required side pushing cylinder is large, the gypsum board edge is easy to break, which inevitably affects the accuracy of the gypsum board quality parameter measurement, causes misjudgment of a gypsum board sampling detection result, and affects the normal production of the production line.
And this embodiment is through dividing into two kinds of transmission modes with sampling mechanism, when not the operation of sampling, sampling mechanism utilizes the gliding no external power mode, carry out the transmission of transition along direction of delivery with the gypsum board, when carrying out the operation of sampling, with the gliding mode side push of sample gypsum board installation to testing platform, the frictional force that the gypsum board received this moment is little, and the dynamics demand that pushes away the cylinder to the offside is little, the cylinder pressure that the gypsum board edge received is little and reduce the possibility that deformation produced relatively, consequently, improve the accuracy that gypsum board quality parameter detected.
As shown in fig. 1 and fig. 2, the online sampling and detecting device for gypsum board production line includes a cutting conveyor belt 1, a lifting and sampling mechanism 2, and a drying conveyor belt 3 in sequence along the conveying direction of gypsum boards, and is characterized in that the lifting and sampling mechanism 2 mainly comprises an upper gypsum board conveying assembly 201 and a lower sliding plate 202 which move up and down synchronously, the upper gypsum board conveying assembly 201 normally conveys gypsum boards in a sliding manner when being reset, the upper gypsum board conveying assembly 201 jacks up gypsum boards to be sampled to a detecting mechanism 4 in a rolling manner when jacking up the gypsum boards, and the lower sliding plate 202 continuously keeps transitive conveying of the cut gypsum boards after sampling the gypsum boards when being jacked up.
As is known well, the gypsum board is firstly cut into the gypsum board with a certain board length through the cutting unit, then the cut gypsum board is continuously transmitted under the driving of the cutting transmission band 1, the sampled gypsum board is transferred to the detection mechanism 4 under the driving of the upper layer gypsum board transmission component 201, and other gypsum boards are continuously transferred to the drying transmission band 3 through the lower layer sliding flat plate 202 to be subjected to subsequent drying treatment, so that the online sampling of the gypsum board is realized, and the continuous production of a gypsum board production line is not influenced.
The innovation points of the embodiment are as follows: after the gypsum board is transferred by the upper gypsum board transmission assembly 201, the upper gypsum board transmission assembly 201 is reset to be flush with the cutting transmission belt 1 and the drying transmission belt 3, the upper gypsum board transmission assembly 201 normally transmits the gypsum board in a sliding mode, and under the driving of the cutting transmission belt 1 and the drying transmission belt 3, the friction force of the sliding mode cannot generate deformation influence on the gypsum board; and when the gypsum board was by jack-up, utilize the roll mode to wait to sample the gypsum board jack-up and shift to detection mechanism 4 during upper gypsum board transmission component 201 jack-up sample gypsum board, the frictional force of roll mode this moment is little, and produces deformation when effectually avoiding the gypsum board to shift to detection mechanism 4.
The specific implementation principle and implementation process are as follows:
the lifting sampling mechanism 2 further comprises an installation base 203 with an upward opening, and a plurality of strip-shaped grooves 204 uniformly arranged on two parallel side surfaces of the installation base 203, a packaging frame 205 is arranged between the two parallel side surfaces of the installation base 203, and the lower end of the packaging frame 205 is provided with an inserted rod 206 which moves up and down along the strip-shaped grooves 204.
The upper gypsum board transmission component 201 and the lower sliding flat plate 202 are parallelly installed on the packaging frame 205, the installation base 203 is provided with a pushing cylinder 207 which is right opposite to the center of the lower sliding flat plate 202, and the length of the upper gypsum board transmission component 201 and the lower sliding flat plate 202 is half of the length of a gypsum board.
The upper gypsum board transmission component 201 and the lower sliding flat plate 202 are integrally integrated on the packaging frame 205, and are integrally lifted and moved under the action of the pushing cylinder 207, so that the pushing cylinder 207 only needs to be lifted to a set value at each time, the set value is the height difference between the upper surface of the lower sliding flat plate 202 and the upper surfaces of the cutting transmission belt 1 and the drying transmission belt 3, and the regulation and control mode is simple and rapid.
The height difference between the upper surface of the lower sliding plate 202 and the upper surface of the cutting transmission belt 1 is also set as the height of the strip-shaped groove 204, therefore, when the lifting sampling mechanism 2 resets, the packaging frame 205 falls to the lowest end of the strip-shaped groove 204 through the inserted link 206, the upper gypsum board transmission assembly 201 is flush with the upper surfaces of the cutting transmission belt 1 and the drying transmission belt 3, when the lifting sampling mechanism 2 lifts, the packaging frame 205 moves up to the uppermost end of the strip-shaped groove 204 through the inserted link 206, and the lower sliding plate 202 is flush with the upper surfaces of the cutting transmission belt 1 and the drying transmission belt 3.
As shown in fig. 3 and 4, upper gypsum board transmission assembly 201 includes that a plurality of groups are evenly installed the dull and stereotyped roller assembly of encapsulation deckle board 205, every group dull and stereotyped roller assembly mainly comprises gyro wheel board 2011 and horizontal plate 2012, the both ends of gyro wheel board 2011 and horizontal plate 2012 all pass through sloping bar 2013 fixed mounting respectively on rotating barrel 2014, rotating barrel 2014 movable mounting be in on the encapsulation deckle board 205, be equipped with interior concave hole groove 2015 on the encapsulation deckle board 205, be equipped with two spacing arc cardboard 2016 along the symmetric distribution on the inner wall of interior concave hole groove 2015, rotating barrel 2014 is in free rotation in the restriction angle of spacing arc cardboard 2016.

The side-push cylinder 8 acts on the plate edge of the gypsum board, when the gypsum board is pushed, the roller 7 rotates around the inserting short rod 6, the friction force applied to the gypsum board is rolling friction force, the rolling friction force is friction generated when an object rolls on another object, and the rolling friction force is much smaller than the maximum static friction force and the sliding friction force, and in general, the rolling friction force is only 1/40 to 1/60 of the sliding friction force.
Because the gypsum board of taking a sample is the wet gypsum board that does not dry, the gypsum board edge takes place the deformation easily under the exogenic action, influence subsequent gypsum board quality testing work, consequently, in order to reduce the side thrust cylinder 8's that the gypsum board edge received thrust size, need corresponding frictional force that reduces the gypsum board and received, this embodiment utilizes sliding friction's mode to shift the gypsum board of taking a sample to weighing platform 401, the frictional force that the gypsum board received this moment is little, and the dynamics demand that pushes away the cylinder to the side is little, the cylinder pressure that the gypsum board edge received is little and reduce the possibility that the deformation produced relatively, consequently, improve the accuracy that gypsum board quality parameter detected.
In the present embodiment, when the cut gypsum board is normally conveyed, the plurality of horizontal plates 2012 form a transition platform for transferring the gypsum board from the cutting conveyor belt 1 to the drying conveyor belt 3, and at this time, since the weight of the roller plate 2011 is greater than that of the horizontal plates 2012, the roller plate 2011 is slightly lower than the upper surface of the horizontal plates 2012, and at this time, the roller plate 2011 does not have any influence on the normally conveyed gypsum board.
When the sampling gypsum board is jacked up and transferred, the rotating barrel 2014 rotates under the action of external force, the upper surface of the roller plate 2011 is flush with the cutting transmission belt 1, the horizontal plate 2012 is slightly lower than the upper surface of the roller plate 2011, the sampling gypsum board is subjected to sliding friction force of the roller plate 2011 when the sampling gypsum board is laterally pushed and transferred under the action of the lateral pushing cylinder 8, and the horizontal plate 2012 cannot generate extra friction force on the gypsum board subjected to sampling and transferring.
According to the above, since the weight of the roller plate 2011 is greater than the weight of the horizontal plate 2012, the roller plate 2011 is slightly lower than the upper surface of the horizontal plate 2012 under the action of no external force, and in order to realize the alternate use of the roller plate 2011 and the horizontal plate 2012, power needs to be additionally added to drive the planar roller assembly to rotate in the forward and reverse directions in a circulating manner.
