Description

Technical Field

[0001] This utility model relates to the field of cargo shower room technology, specifically a collision-resistant high-speed rolling door cargo shower room. Background Technology

[0002] A cargo air shower, also known as a cargo shower room, is an essential passage for goods entering a cleanroom. It reduces contamination caused by goods entering and exiting the cleanroom. Goods entering the clean area are blown away by a fan through air shower nozzles, using highly efficient filtered clean air to remove dust adsorbed on the surface of objects. It is a highly versatile local purification device installed between the cleanroom and non-cleanroom. When people and goods need to enter the clean area, they must pass through the air shower. The clean air blown out removes dust carried by people and goods, effectively blocking or reducing dust sources from entering the clean area. The front and rear doors of the cargo air shower are electronically interlocked, also functioning as an airlock to prevent unpurified air from entering the clean area.

[0003] Chinese patent CN208555312U discloses an anti-collision type high-speed rolling shutter door cargo shower chamber, which includes a connected conveying cargo shower chamber and a unloading cargo shower chamber. An electrically controlled door is provided between the conveying cargo shower chamber and the unloading cargo shower chamber. A conveyor belt is provided in the conveying cargo shower chamber. Main nozzles are provided on the inner walls of the conveying cargo shower chamber located on both sides of the conveyor belt. An unloading platform is provided in the unloading cargo shower chamber and spliced ​​to the end of the conveyor belt.

[0004] Regarding the aforementioned disclosed technology, existing cargo shower rooms require staff to push goods into the shower room using a forklift. Existing cargo shower rooms are often equipped with two sets of roller shutters. When goods are pushed in from one set of roller shutters, they are likely to collide with the other set of roller shutters, which will affect the service life of the cargo shower room's roller shutters.

[0025] Please see Figure 1-5 A collision-resistant high-speed rolling shutter door 3 and a cargo shower chamber 1 are disclosed. The cargo shower chamber 1 has passageways on both its left and right sides. A rolling shutter mechanism for sealing the cargo shower chamber 1 is installed within each passageway. The rolling shutter door 3 mechanism includes a cavity 6 within the cargo shower chamber 1, a winding wheel 7 rotatably mounted within the cavity 6, and a rolling shutter door 3 wound around the winding wheel 7. A transparent window 4 is provided on the rolling shutter door 3. A matrix of nozzles 8 are arranged on the inner walls of both sides of the cargo shower chamber 1. A rectangular groove is formed on the inner wall of the bottom of the cargo shower chamber 1, and a sliding mechanism is installed within the rectangular groove. The shower chamber 1 is equipped with a movable baffle 16. A transmission cavity 20 is opened inside the shower chamber 1. A servo motor 9 is installed in the transmission cavity 20. A take-up roller 10 is installed on the output shaft of the servo motor 9. A traction line 13 is installed on the take-up roller 10. The two ends of the traction line 13 are symmetrically connected to the two ends of the movable baffle 16. Two mutually symmetrical drive motors 2 are installed on one side of the shower chamber 1. The output shaft of the drive motor 2 is installed on the take-up roller 7. A control panel 5 is installed on the shower chamber 1. The control panel 5 is electrically connected to the two drive motors 2 and the servo motor 9.

[0026] The usage and internal structure of the nozzle 8 and roller shutter 3 are existing technologies for spray chambers and will not be elaborated here. Through the cooperation of the winding roller 10, traction line 13 and movable baffle 16, after the goods enter the spray chamber 1, the servo motor 9 is started to drive the winding roller 10 to rotate, so that the traction line 13 can be wound around the winding roller 10. This causes the two ends of the traction line 13 to drive the movable baffle 16 to rise vertically. The raised movable baffle 16 blocks the goods and prevents the goods from hitting the roller shutter 3.

[0027] Specifically, in this embodiment, two symmetrical vertical sliding grooves 15 are provided in the cargo shower chamber 1 and are connected to the transmission cavity 20. Two symmetrical sliding shafts 21 are provided in the transmission cavity 20. The two ends of the traction line 13 pass around the two sliding shafts 21 and extend into the vertical sliding grooves 15. A maintenance cover plate 11 is fastened to the opening of the vertical sliding groove 15. The maintenance cover plate 11 is connected and fixed to the cargo shower chamber 1 by connecting bolts. A rectangular vertical through hole 12 is provided on both maintenance cover plates 11. Two symmetrical protrusions 24 that are adapted to the rectangular vertical through holes 12 are provided on the movable baffle 16.

[0028] The vertical sliding groove 15 and the inspection cover 11 facilitate the maintenance of the traction line 13. The rectangular vertical through hole 12 and the protrusion 24 on the inspection cover 11 work together to restrict the movement direction and range of the movable stop bar 16.

[0029] Specifically, in this embodiment, the movable stop bar 16 is provided with a plurality of dampers 17 distributed axially at intervals. The movable ends of the plurality of dampers 17 are equipped with the same rubber buffer strip 19. Each of the plurality of dampers 17 is fitted with a buffer spring 18. One end of the buffer spring 18 abuts against the movable stop bar 16, and the other end of the buffer spring 18 abuts against the rubber buffer strip 19.

[0030] By incorporating dampers 17, buffer springs 18, and rubber buffer strips 19, the impact force can be buffered by the deformation of the rubber buffer strips 19 and buffer springs 18 when the movable baffle 16 is hit by cargo, and the energy can be absorbed by the multiple dampers 17 connected to the rubber buffer strips 19, thus achieving the overall buffering purpose.

[0031] Specifically, in this embodiment, both ends of the traction line 13 are provided with connecting blocks 22, and the top of the movable stop bar 16 is provided with two mutually symmetrical locking blocks 14. The locking blocks 14 are provided with grooves into which the connecting blocks 22 can be inserted, and the openings of the grooves are fastened with locking blocks 23.

[0032] The cooperation of connecting block 22, locking block 14 and fastening block 23 makes it easy to quickly detach and assemble the traction line 13 and the movable stop bar 16.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
