Description

Technical Field

[0001] This invention relates to the field of latex matrix thickness detection technology, specifically to a latex matrix thickness detection system and its working method. Background Technology

[0002] Latex matrix is ​​a semi-finished product of emulsion explosives. It is a water-in-oil emulsion formed by emulsifying a solution of oxidizing agents such as ammonium nitrate and sodium nitrate as the dispersed phase and a solution of carbonaceous fuels such as specific composite waxes, mineral oils, and emulsifiers as the continuous phase. The latex matrix is ​​a brown or brownish translucent substance. Its quality directly affects the performance of emulsion explosives. Emulsion explosives generally refer to a class of water-in-oil (W / O) emulsion-like aqueous industrial explosives prepared by emulsification technology, in which microdroplets of oxidizing agent salt solutions are uniformly dispersed in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres. Emulsion explosives are a type of aqueous explosive and are currently widely used both domestically and internationally.

[0003] Most existing latex matrix thickness measurement methods rely on clamping and observing scale lines for detection. This method only measures a single location and fails to detect areas of varying thickness on the latex matrix surface, resulting in inaccurate thickness measurement. To address this, we provide a latex matrix thickness measurement system and its operating method. Summary of the Invention

[0012] Preferably, the connecting stand has an internal mounting cavity with one side opening. A second electric push rod is installed inside the mounting cavity. A push rod base is welded to the lower end of the second electric push rod, and the second electric push rod is fixed to the connecting stand by external bolts to the push rod base. A connecting rod is installed at the upper end of the second electric push rod, and one end of the connecting rod is welded to the upper detection seat. The connecting rod is threadedly connected to the second electric push rod by hexagonal bolts.

[0013] Preferably, the lower end of the lower detection seat is provided with a first electric push rod, and push rod mounting plates are welded to both ends of the first electric push rod. The two ends of the first electric push rod are threadedly connected to the lower detection seat and the movable base respectively through the external threaded fasteners of the push rod mounting plates.

[0014] Preferably, the support base has an internal mounting groove, and the mounting groove and the support base are an integral structure. The mounting groove has a slide rail fixing base plate inside, and fixing bolts are provided at the corners of the slide rail fixing base plate. The slide rail fixing base plate is threadedly connected to the support base through the fixing bolts. A servo motor is provided at one end of the slide rail fixing base plate, and a ball screw is provided at one end of the servo motor. A ball screw moving seat is provided outside the ball screw, and the moving base is threadedly connected to the ball screw moving seat through a single-head fastener.

[0015] Preferably, the upper ends of the first side plate and the second side plate are each provided with a right-angle mounting plate, and the two right-angle mounting plates are each provided with a fixing groove between the first side plate and the second side plate. The upper end of the right-angle mounting plate is provided with a cylinder, and one end of the cylinder is provided with a pressure seat.

[0016] Preferably, both the lower and upper detection seats have maintenance openings on their front surfaces, and protective covers are installed inside the maintenance openings. Each protective cover has a fixing screw at its corner, and the two protective covers are threadedly connected to the lower and upper detection seats respectively by the fixing screws.

[0017] Preferably, the operating method of the latex matrix thickness detection system includes the following steps:

[0018] Step 1: Place the latex matrix inside the two fixed slots, then start the cylinder. The cylinder drives the lower pressure seat to move down, squeezing the latex matrix.

[0019] Step 2: Start the servo motor, the ball screw rotates, and the screw moving seat moves along the ball screw until the screw moving seat moves to the end closest to the servo motor, and the moving base is located on the support base;

[0020] Step 3: Activate the first and second electric push rods. The lower detection seat moves up and the upper detection seat moves down. The upper and lower contact plates contact the upper and lower surfaces of the latex matrix respectively. The upper and lower contact plates are squeezed according to the shape of the latex matrix surface. The compression springs connected to the upper and lower contact plates deform, and the upper and lower contact plates move up and down.

[0021] Step 4: After extrusion, activate the infrared distance sensor to measure the distance between the upper and lower contact plates and display it on the digital display screen. The displayed value is the thickness of the latex matrix at different locations.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention involves setting a lower detection seat above a support base and an upper detection seat above the lower detection seat. A lower contact plate and an upper contact plate with compression springs are respectively installed inside the adjustment cavities of the lower and upper detection seats. The latex matrix is ​​placed inside the two fixing slots. Then, a cylinder is activated, causing the lower pressure seat to move downwards, compressing and fixing the latex matrix to prevent slippage. The latex matrix between the first and second side plates is located between the lower and upper detection seats. A first and second electric push rod respectively drive the lower and upper detection seats to move upwards and downwards, respectively. The upper contact plate and the lower... The contact plates make contact with the upper and lower surfaces of the latex matrix, respectively. The upper and lower contact plates are compressed according to the shape of the latex matrix surface. The compression springs connected to the upper and lower contact plates deform, causing them to move up and down, thus making contact with different thicknesses of the latex matrix surface. An infrared distance sensor measures the distance between the upper and lower contact plates, which is displayed on a digital display screen. This number represents the thickness of the latex matrix. The thickness at different locations is displayed sequentially. This multi-point testing improves the accuracy of latex matrix thickness measurement.

[0024] 2. By setting an installation groove inside the support base, the slide rail, consisting of a servo motor, ball screw, screw moving seat, and slide rail fixing base plate, is installed inside the installation groove. When the servo motor is started, the ball screw rotates, which drives the screw moving seat to move, thereby realizing the movement of the movable base. When placing the latex substrate, the movable base moves backward, so that the lower and upper detection seats are away from the first and second side plates, avoiding accidental contact with the latex substrate and causing damage or installation obstruction. After the latex substrate is placed, the screw moving seat drives the movable base to the end closest to the servo motor, and the lower and upper detection seats are located between the first and second side plates, clamping the latex substrate from top to bottom.

[0025] 3. By setting limiting baffles on one end surface of both the lower and upper contact plates, the infrared ranging sensor and the latex matrix placement area are separated by the limiting baffles. This prevents the infrared ranging sensor from being blocked when the latex matrix is ​​placed, thereby reducing the impact on the latex matrix thickness measurement and improving measurement stability.

Multi-point testing improves the accuracy of latex matrix thickness measurement. When the upper contact plate 15 and the lower contact plate 14 move up and down, the telescopic sleeve 41 moves along the outside of the telescopic rod 40, thereby limiting the movement of the upper contact plate 15 and the lower contact plate 14 to only move up and down, avoiding forward, backward, left and right deviations and improving stability. The measured thickness is set to not exceed 12mm. When the predetermined value is exceeded, an electrical signal is transmitted to the audible and visual alarm 42 to provide an audible and visual alarm reminder.
