The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0042] See also Figure 1-Figure 6The present embodiment provides a thickness detection device for quartz stone slab production, including a base 100, on which an electric conveyor belt assembly 200 parallel to the base 100 is arranged, the electric conveyor belt assembly 200 is composed of a conveyor belt, a rotating motor, and a support frame, and the conveyor belt is controlled by the rotating motor. The top of the base 100 is equipped with a bracket 300, and a hollow slider 500 is slidably connected between the electric conveyor belt assembly 200 and the bracket 300 through two first positioning rods 600, and a caliper 700 is installed on the side of the hollow slider 500, which is rotated The motor controls the conveyor belt to move to transport the quartz stone plate to be tested. The top of the bracket 300 is equipped with a hydraulic telescopic module 400 for controlling the movement of the hollow slider 500. The hydraulic telescopic module 400 is composed of a hydraulic oil pump and a hydraulic telescopic rod. The hydraulic telescopic rod is embedded in the top of the bracket 300, and the extension rod of the hydraulic telescopic rod is connected to the hollow slider 500. The hydraulic oil is filled into the hydraulic telescopic rod through the hydraulic oil pump, so that the extension rod of the hydraulic telescopic rod pushes the hollow slider 500 to move. The hollow slider 500 is equipped with multiple groups of detection components 800 for detecting the thickness of the plate.

[0043] The detection component 800 includes:

[0044] A T-shaped rod 810 is passed through and slidably connected to the inside of the hollow slider 500. The bottom of the T-shaped rod 810 is rotatably connected to a contact wheel 830. The contact wheel 830 is used to contact the surface of the quartz stone plate to be tested to perform thickness detection. At the same time, due to the rotatable nature of the contact wheel 830, friction loss between the quartz stone plate and the contact wheel 830 can be avoided during the detection process. Second positioning rods 840 are passed through and slidably connected on both sides of the T-shaped rod 810, and two of the second positioning rods 840 are fixed in the hollow slider 500. The movement trajectory of the T-shaped rod 810 is secondarily limited by the two second positioning rods 840 to ensure that each single The movement direction of the T-shaped rod 810 is vertical up and down. Two symmetrically arranged springs are fixed between the top of the T-shaped rod 810 and the hollow slider 500. The springs are arranged to ensure that the T-shaped rod 810 of each detection component 800 is in the same plane when it is reset, so as to ensure the accuracy of the thickness detection operation. At the same time, due to the existence of the springs, the T-shaped rod 810 is given an extrusion force. When the contact wheel 830 detects a pit or a protrusion defect on the surface of the quartz stone plate, the T-shaped rod 810 can be moved in time. A trigger rod 850 is fixed on the top of the T-shaped rod 810, and the trigger rod 850 is F-shaped;

[0045] An L-shaped hydraulic chamber 860 is fixed inside the hollow slider 500 by a connecting rod 870. A movable rod 880 is slidably connected to the piston at one end of the L-shaped hydraulic chamber 860. The movable rod 880 is in a double-sided trapezoid. The two inclined surfaces of the movable rod 880 respectively fit the two horizontal blocks of the trigger rod 850. A push rod 890 is slidably connected to the piston at the other end of the L-shaped hydraulic chamber 860. The push rod 890 is connected to the marking rod assembly 820. The trigger rod 850 is in an F-shape. No matter when the trigger rod 850 moves upward or downward, the inclined surface of the movable rod 880 can be squeezed by the horizontal blocks on its side, thereby pushing the movable rod 880 to move, so that the present application can not only detect protrusions of the quartz stone slab, but also detect pits.

[0046] The marking rod assembly 820 assembled on the hollow slider 500 is used to mark the defects of the plate. In this embodiment, the marking rod assembly 820 can be replaced by a marking pen. The marking pen is connected to the bottom of the push rod 890 through a connecting piece (not shown in detail in the drawings). The marking rod assembly 820 is located on the side of the T-shaped rod 810.

[0047] When the present application detects the thickness of the quartz stone plate, the quartz stone plate to be tested is first placed on the upper surface of the conveyor belt, and the conveyor belt is controlled to move by a rotating motor to slowly transport the quartz stone plate to the bottom of the detection component 800. Then, the hydraulic oil pump is started to fill the hydraulic oil in the hydraulic oil tank into the hydraulic telescopic rod through a hose, so that the extension rod of the hydraulic telescopic rod pushes the hollow slider 500 to move, and the detection component 800 is driven to move downward as a whole through the hollow slider 500. When the contact wheel 830 contacts and squeezes the quartz stone plate to be tested, the hydraulic oil pump is turned off to locate the position of the hollow slider 500, and then the thickness of the quartz stone plate to be tested is determined by observing the caliper 700.

[0048] At the same time, in order to detect the surface defects of the quartz stone plate, the detection component 800 starts to work. Due to the movement of the hollow slider 500, the contact wheels 830 in the multiple detection components 800 are in contact with the surface of the quartz stone plate to be tested. At this time, due to the movement of the conveyor belt, the quartz stone plate to be tested continues to move slowly. At this time, the contact wheel 830 rotates. As the contact wheel 830 rolls on the quartz stone plate to be tested, once a convex or concave defect appears on the quartz stone plate to be tested, the contact wheel 830 will drive the T-shaped rod 810 to move upward or downward. At the same time, the F-shaped trigger rod 850 fixed on the T-shaped rod 810 will move synchronously. Regardless of the trigger rod 850, When moving upward or downward, the inclined surface of the movable rod 880 can be squeezed by the horizontal block on its side, thereby pushing the movable rod 880 to move to the right. As the movable rod 880 moves, the liquid pressure in the L-shaped hydraulic chamber 860 increases, prompting the push rod 890 to move downward, thereby pushing the marking rod assembly 820 to move downward. In this embodiment, the marking rod assembly 820 is a marking pen. Therefore, when the push rod 890 moves downward, it will push the marking pen to move downward to mark the defects of the quartz stone slab. Since the marking rod assembly 820 is located on the side of the T-shaped rod 810 and is driven by direct linkage, there will be no marking delay, making the marking more accurate. Example

[0049] See also Figure 7-10On the basis of the first embodiment, the marking rod assembly 820 in this embodiment includes a rod body 821 penetrating and slidably connected to the inside of the hollow slider 500, a fixing rod 827 fixed to the bottom of the hollow slider 500, and springs 822 are fixed between the two sides of the rod body 821 and the hollow slider 500. The bottom side of the rod body 821 is rotatably connected to a marking wheel 823, and a plurality of balls 8210 are mounted on the outer side of the marking wheel 823. The setting of the balls 8210 can minimize the friction loss between the marking wheel 823 and the quartz stone plate. The front end of the marking wheel 823 is fixed The fixed rod 827 is provided with a gear 826, and the end of the left side of the fixed rod 827 near the gear 826 is rotatably connected with a tooth 828 through a torsion spring hinge 829. Since the tooth 828 is connected to the fixed rod 827 through the torsion spring hinge 829, the tooth 828 and the gear 826 are in a one-way meshing state. Therefore, only when the gear 826 moves downward can it be driven to rotate by the tooth 828, and when the gear 826 moves upward, it will drive the tooth 828 to rotate, and will not cause the gear 826 to rotate in the opposite direction. The rod body 821 is provided with a hollow groove 824 inside, and one end of the hollow groove 824 is Located on the side of the rod body 821, the other end of the hollow groove 824 is close to the marking wheel 823, and the hollow groove 824 is filled with a marking ink 825. The hollow groove 824 is set to facilitate the storage of the marking ink 825. A through groove is opened in the middle of the marking wheel 823, and a plurality of positioning holes 8215 are opened on the inner wall of the through groove. The side of the rod body 821 is located in the middle of the marking wheel 823. A cylindrical rod 8211 is fixed in the middle of the through groove. An elastic telescopic rod 8212 is embedded in the cylindrical rod 8211. The elastic telescopic rod 8212 is composed of a hollow tube 8213. It is slidably connected with the sliding rod 8214, and a spring is fixed between the hollow tube 8213 and the sliding rod 8214. The top of the sliding rod 8214 is a hemispherical structure. Through the elastic telescopic rod 8212 and the positioning hole 8215 opened on the inner wall of the marking wheel 823, a certain positioning effect is given to the marking wheel 823. The hemispherical structure at the top of the sliding rod 8214 can adapt to the positioning hole 8215 opened on the inner wall of the marking wheel 823. The marking wheel 823 contacts the marking ink 825 through the ball 8210 on its outer side, and then performs marking, which can achieve the effect of quick marking.

[0050] During use, based on the first embodiment, when the rod body 821 is pushed downward by the push rod 890, the marking wheel 823 is driven to move downward. At this time, the surface defects of the quartz stone plate to be tested are marked by the ball 8210 arranged on the outside. In order to ensure that each ball 8210 is attached with the marking ink 825, each time the rod body 821 moves downward, the side of the fixed rod 827 is connected to the tooth 828 through the torsion spring hinge 829, which will drive the gear 826 to rotate counterclockwise. The rotation of the gear 826 drives the marking wheel 823 to rotate, so that the position of the ball 8210 changes. In this way, each ball 8210 can contact the marking ink 825. At the same time, because the tooth 828 is connected to the fixed rod 827 through the torsion spring hinge 829, the tooth 828 and the gear 826 are in a one-way meshing state. 26 moves downward, it can be driven by the tooth 828 to rotate, and when the gear 826 moves upward, it will drive the tooth 828 to rotate, and will not cause the gear 826 to rotate in the opposite direction, so that the marking wheel 823 can rotate once for each mark, so that the ball 8210 arranged on its outside contacts the marking ink 825 once, ensuring that each ball 8210 is attached with the marking ink 825, ensuring the stability of the mark, and ensuring that each ball 8210 is attached with the marking ink 825. At the same time, in order to ensure that the angle of each rotation of the marking wheel 823 is constant, the sliding rod 8214 in the elastic telescopic rod 8212 on the cylindrical rod 8211 cooperates with the positioning hole 8215 on the inner wall of the marking wheel 823, so that the positioning hole 8215 in the marking wheel 823 after each rotation is just movably engaged with the top of the sliding rod 8214 in the elastic telescopic rod 8212.
