Description

Technical Field

[0001] The present invention relates to the technical field of detecting the spraying amount of mildew-proof powder on float glass, and in particular to a device and a method for detecting the spraying amount of mildew-proof powder on float glass. Background Art

[0002] In the float glass production process, mildew-proof powder plays the role of isolation and moisture-proof between float glass sheets, so it is widely used in glass production. Different climate environments have different requirements for the amount of mildew-proof powder sprayed, and the measurement of the amount of mildew-proof powder sprayed is a necessary process in the float glass industry.

[0003] In the prior art, the float glass production plant measures the amount of powder by manual assisted measurement, usually by two people working together to receive and take the anti-mildew powder online. The specific operation is: one person places a powder collecting plate at the front end of the powder sprayer on the production line, and the other collects the powder plate at the rear end of the powder sprayer. Since the roller speed changes with the thickness of the glass plate, especially when the glass is thin, the roller speed is fast. Even if two people work together, it is easy for the powder collecting plate to fail to be collected and the glass transmitted in front and behind to collide. In addition, the detection method of workers placing and taking the plate is low in efficiency, which increases the labor cost. In addition, in the prior art, the powder collecting plate is generally placed manually on one side of the roller, or two people on both sides of the roller place the powder collecting plate on both sides of the roller at the same time. This placement and collection method of the powder collecting plate is low in efficiency and automation, and on the other hand, it cannot comprehensively collect the anti-mildew powder sprayed from various positions of the powder sprayer, and the detection data is inaccurate.

[0030] like Figure 1 The figure shows a schematic diagram of the first embodiment of the present application, including a conveying roller 100, a powder sprayer 200, a lifting mechanism 300 and a powder collecting mechanism; the powder sprayer 200 is mounted above the conveying roller 100, and the lifting mechanism 300 is arranged at one end of the conveying roller 100 for transferring the powder collecting mechanism to the conveying roller 100; the lifting mechanism 300 includes a pair of lifting cylinders and a carrying plate, the piston ends of the pair of lifting cylinders are respectively fixedly connected to the bottom surfaces on both sides of the carrying plate, and the powder collecting mechanism is placed on the carrying plate and is lifted and moved by the extension and contraction of the piston ends of the pair of lifting cylinders; a photoelectric sensor is provided on the side of the powder sprayer 200 corresponding to the conveying roller 100; the powder collecting mechanism includes a powder collecting plate 400 arranged corresponding to the powder sprayer 200, and a plurality of partitions are arranged in the powder collecting plate 400 to separate the powder collecting plate 400 into a plurality of powder collecting parts 410.

[0031] In this embodiment, the lifting mechanism 300 is arranged on one side of the conveying roller 100, and the powder collecting mechanism is placed behind the carrying plate of the lifting mechanism 300. The lifting cylinder drives the lifting and lowering of the powder collecting mechanism. When the powder collecting mechanism moves to be flush with the conveying roller 100, it contacts the conveying roller 100, and is transferred to the conveying roller 100 as the conveying roller 100 rotates. When the powder collecting mechanism moves to the position corresponding to the position below the powder sprayer 200, since the powder sprayer 200 is provided with a photoelectric sensor, the powder sprayer 200 is driven to start spraying anti-mildew powder downward into the powder collecting plate 400 of the powder collecting mechanism. After the spraying is completed, the powder collecting mechanism moves to the end of the conveying roller 100, collects and weighs the anti-mildew powder in each powder collecting part 410 in the powder collecting plate 400, and completes the detection of the spraying amount of the powder sprayer 200, thereby adjusting the actual spraying amount according to the required spraying amount. In this embodiment, the powder collecting plate 400 is set to a size that fully covers the spraying area of ​​the powder sprayer 200, thereby completing the comprehensive collection of the spraying amount of the powder sprayer 200, making the collected anti-mildew powder data more accurate. Compared with the prior art, it has a high degree of automation, covers all positions of the powder sprayer 200 to collect anti-mildew powder, so the detection data is more accurate.

[0032] In a preferred embodiment, each of the powder collecting parts 410 is provided with a collecting outlet at the bottom thereof, and a detachable cover 411 is provided on the collecting outlet. In this preferred embodiment, the anti-mildew powder collected in the powder collecting part 410 is transferred to a detection and collecting container outside the powder collecting mechanism through the collecting outlet, so as to facilitate the measurement of the quality of the anti-mildew powder.

[0033] Preferably, the bottom of the powder collecting portion 410 corresponding to the collecting outlet is provided with an inclined surface structure inclined toward the collecting outlet. The inclined surface structure in the powder collecting portion 410 facilitates the transfer and discharge of the anti-mildew powder out of the powder collecting portion 410.

[0034] In a preferred embodiment, two partitions are provided in the powder collecting tray 400 , and the powder collecting tray 400 is divided into three powder collecting portions 410 by the two partitions. In this embodiment, the powder collecting tray 400 covers the spraying area of ​​the powder sprayer 200 .

[0035] In a preferred embodiment, a pair of guardrails 500 are disposed on both sides of the conveying roller 100 , and the setting direction of the guardrails 500 is consistent with the conveying direction of the conveying roller 100 . The powder sprayer 200 is installed above the pair of guardrails 500 .

[0036] In a preferred embodiment, a buffer guard plate and an electric telescopic rod for driving the buffer guard plate to rise and fall are provided on the end of the conveying roller 100 away from the lifting mechanism 300. In this preferred embodiment, a buffer guard plate is provided at the end corresponding to the collection of the conveying roller 100. When the powder collecting mechanism is conveyed to the collection end on the conveying roller 100, the buffer guard plate provides a blocking effect on the powder collecting mechanism, thereby preventing the powder collecting mechanism from collecting untimely and colliding with the glass conveyed in front and behind.

[0037] In a preferred embodiment, Figure 2 As shown, the side of the guardrail 500 corresponding to the buffer guard plate 600 is provided with an inwardly recessed slot, and the side of the buffer guard plate 600 corresponding to the slot is provided with an outwardly protruding protrusion 610, and the protrusion 610 can be slidably inserted in the slot. In this preferred embodiment, when the buffer guard plate 600 is lifted and moved, its protrusion 610 is always inserted in the slot of the guardrail 500, thereby improving the stability of the buffer guard plate 600 when it is lifted and moved.

[0038] In a preferred embodiment, Figure 3 As shown, the top of the side edge of the guardrail 500 corresponding to the buffer guard plate 600 is provided with a protruding height limiting piece 510, and the surface of the height limiting piece 510 close to the buffer guard plate 600 is inwardly recessed with a positioning groove 511, and the top of the side edge of the buffer guard plate 600 is provided with a protruding positioning portion 620 that can abut against the positioning groove 511. In this preferred embodiment, the setting of the limiting piece plays a role in limiting the highest position when the buffer guard plate 600 is lifted or lowered.

[0039] In a preferred embodiment, Figure 4As shown, the top surface of the side edge of the buffer guard plate 600 is inwardly recessed with a buffer groove 630, and the positioning portion 620 is connected to the bottom of the buffer groove 630 through a buffer spring 640. In this preferred embodiment, when the buffer guard plate 600 abuts against the height limiting sheet 510, the positioning portion 620 abuts against the positioning groove 630, which plays a role in abutting and positioning the buffer guard plate 600. At the same time, the setting of the spring 640 can play a buffering role when the buffer guard plate 600 abuts, thereby ensuring the stability of the device operation.

[0040] like Figure 5 The second embodiment of the present application is shown, which is a detection method using the first embodiment for detection, comprising the following steps:

[0041] S1. Start the lifting cylinder to control the extension of the piston end of the lifting cylinder.

[0042] S2. When the load-bearing plate connected to the piston end of the lifting cylinder is higher than the surface of the conveying roller, the lifting cylinder is paused.

[0043] S3. Place the powder collecting mechanism on the carrying plate.
