Description

Technical Field

[0001] This utility model belongs to the field of sandblasting machine protection technology, and more specifically, it relates to an intelligent sandblasting monitoring and protection device. Background Technology

[0002] Automatic sandblasting machines are mostly equipped with protective curtains at their inlet and outlet by bolts. These curtains block the abrasive and dust that splash during the sandblasting process, protecting the surrounding environment and personnel safety. The protective curtains are mostly made of wear-resistant and corrosion-resistant materials and have a long service life.

[0003] Based on the above, when the workpiece enters or exits the automatic sandblasting machine, the workpiece will push the protective curtain, causing the protective curtain to vibrate. At this time, the dust adhering to the inside of the protective curtain will be scattered again, affecting the protective curtain's dust blocking effect. As a result, more dust will drift out of the working area of ​​the automatic sandblasting machine, affecting the protective effect of the protective curtain. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an intelligent sandblasting monitoring and protection device. This device solves the problem that when a workpiece enters or exits an automatic sandblasting machine, it pushes the protective curtain, causing it to vibrate. This causes dust adhering to the inside of the protective curtain to disperse again, affecting the curtain's dust-blocking effect and resulting in a large amount of dust escaping from the working area of ​​the automatic sandblasting machine, thus impacting the protective effect of the curtain.

[0005] The purpose and effectiveness of this intelligent sandblasting monitoring and protection device are achieved through the following specific technical means:

[0006] An intelligent sandblasting monitoring and protection device includes a positioning mounting frame, a dust protective curtain, an adhesive dust-blocking sheet, a first limiting mounting frame, a second limiting mounting frame, a positioning structure, a limiting structure, a detection structure, and a sliding mounting plate. The dust protective curtain is disposed on the lower side of the positioning mounting frame. The adhesive dust-blocking sheet is attached to the rear end face of the dust protective curtain. Multiple first limiting mounting frames are provided, and the multiple first limiting mounting frames are evenly distributed and fixedly connected to the front end face of the positioning mounting frame. Multiple second limiting mounting frames are provided, and the multiple second limiting mounting frames are evenly distributed and fixedly connected to the front end face of the positioning mounting frame. The positioning structure is disposed on the front side of the positioning mounting frame. The detection structure is disposed on the front side of the positioning mounting frame. The sliding mounting plate is slidably connected to the lower side of the multiple second limiting mounting frames. The limiting structure is disposed on the front side of the positioning mounting frame.

[0007] Furthermore, the positioning structure includes a second reset elastic element and a positioning connecting plate; the positioning connecting plate is fixedly connected to the rear end face of the sliding mounting plate; multiple second reset elastic elements are provided, and the positioning connecting plate is elastically connected to multiple second limiting mounting brackets through multiple second reset elastic elements.

[0008] Furthermore, the positioning structure also includes position fixing holes and position fixing blocks; multiple position fixing holes are provided, and the multiple position fixing holes are evenly distributed and opened on the upper part of the dust protection curtain; multiple position fixing blocks are provided, and the multiple position fixing blocks are evenly distributed and fixedly connected to the rear end face of the positioning connecting plate, and the multiple position fixing blocks are respectively inserted into the multiple position fixing holes.

[0009] Furthermore, the detection structure includes a dust concentration sensor and an audible and visual alarm; multiple dust concentration sensors are provided, and the multiple dust concentration sensors are respectively fixedly connected to the lower part of multiple first limiting mounting brackets; multiple audible and visual alarms are provided, and the multiple audible and visual alarms are respectively bolted to the upper part of multiple first limiting mounting brackets, and the control circuits of the multiple audible and visual alarms are respectively connected in series with the control circuits of the multiple dust concentration sensors.

[0010] Furthermore, the limiting structure includes a high-strength fiber mesh and a position limiting frame; the high-strength fiber mesh is disposed in the middle of the dust protection curtain; two position limiting frames are provided, and the two position limiting frames are respectively fixedly connected to the left and right sides of the second limiting mounting frame in the middle.

[0011] Furthermore, the limiting structure also includes a sliding limiting ring and a first reset elastic element; two sliding limiting rings are provided, and both sliding limiting rings are slidably connected to the middle of the sliding mounting plate; multiple first reset elastic elements are provided, and the two sliding limiting rings are elastically connected to the sliding mounting plate through multiple first reset elastic elements.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention uses adhesive dust-blocking sheets to adhere dispersed dust to the dust protection curtain, thus preventing dust from scattering again when the curtain vibrates. This ensures the curtain's effective dust blocking, reduces dust escaping from the automatic sandblasting machine's working area, and improves the curtain's protective effect. A dust concentration sensor and an audible and visual alarm monitor the dust concentration at the automatic sandblasting machine's inlet and outlet. When the dust concentration is too high, an alarm is triggered, reminding operators to immediately shut down the automatic sandblasting machine and replace the adhesive dust-blocking sheets. Simply replacing the adhesive dust-blocking sheets solves the problem. The process of cleaning the inside of the dust protective curtain effectively avoids the inconvenience of using tools to clean it, improves cleaning efficiency, saves a lot of time, and reduces the workload of workers. The high-strength fiber mesh improves the tear resistance of the dust protective curtain, reducing the possibility of breakage. The sliding limit ring limits the forward and backward movement of the sliding mounting plate, effectively preventing the dust protective curtain from shaking and falling off when it is impacted, thus ensuring the installation stability of the dust protective curtain.

The positioning structure is disposed on the front side of the positioning mounting frame 1. The detection structure is disposed on the front side of the positioning mounting frame 1. The sliding mounting plate 6 is slidably connected to the lower side of multiple second limiting mounting frames 5.

[0025] The positioning structure includes a second reset elastic element 603 and a positioning connecting plate 604; the positioning connecting plate 604 is fixedly connected to the rear end face of the sliding mounting plate 6; multiple second reset elastic elements 603 are provided, and the positioning connecting plate 604 is elastically connected to multiple second limit mounting brackets 5 through multiple second reset elastic elements 603.

[0026] The positioning structure also includes position fixing holes 202 and position fixing blocks 605; multiple position fixing holes 202 are provided, and the multiple position fixing holes 202 are evenly distributed and opened on the upper part of the dust protection curtain 2; multiple position fixing blocks 605 are provided, and the multiple position fixing blocks 605 are evenly distributed and fixedly connected to the rear end face of the positioning connecting plate 604, and the multiple position fixing blocks 605 are respectively inserted into the multiple position fixing holes 202.

[0027] The detection structure includes a dust concentration sensor 401 and an audible and visual alarm 402. Multiple dust concentration sensors 401 are provided, and the multiple dust concentration sensors 401 are fixedly connected to the lower part of multiple first limiting mounting brackets 4.

The control circuits of the multiple audible and visual alarms 402 are connected in series with the control circuits of the multiple dust concentration sensors 401.

[0028] The specific usage and function of this embodiment are as follows: The positioning mounting bracket 1 is fixed to the upper part of the inlet and outlet of the automatic sandblasting machine using bolts. Then, the dust protection curtain 2 is pushed upwards along the positioning mounting bracket 1. At this time, the dust protection curtain 2 will squeeze the position fixing block 605, causing the position fixing block 605 and the positioning connecting plate 604 to push the sliding mounting plate 6 forward along the second limiting mounting bracket 5. When the position fixing block 605 aligns with the position fixing hole 202, the second reset elastic element 603 will push the position fixing block 605 and the positioning connecting plate 604 to reset, allowing the position fixing block 605 to insert into the position.

[0029] Example 2:

[0030] As attached Figure 1 To be continued Figure 5 As shown:
