[0031] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the implementation manners of the present utility model in detail with reference to the accompanying drawings.

[0032] Please refer to Figures 1 - 8 , which shows a schematic structural diagram of an implementation manner of a power roller conveyor device for air conditioner assembly of the present utility model. Please refer to Figures 1 - 8 , and a detailed introduction to a power roller conveyor device for air conditioner assembly will be given.

[0033] A power roller conveyor device for air conditioner assembly includes a side plate frame 100. There are two side plate frames 100 in total, which are arranged symmetrically and parallel to each other left and right;

[0034] A telescopic roller 200 for conveying air conditioner fittings is rotatably arranged at equal intervals between the two side plate frames 100. The telescopic roller 200 includes an adjusting rod 210 that rotatably penetrates the side wall of the left side plate frame 100. An outer side of the rod body of the adjusting rod 210 is provided with a first roller 220. One end of the rod body of the adjusting rod 210 located inside the cavity of the first roller 220 is provided with an external thread 230. The side wall of the right side plate frame 100 is rotatably penetrated and provided with an adjusting cylinder 240. The left end of the adjusting cylinder 240 rotatably penetrates the left side of the first roller 220 and is screwed with the external thread 230;

[0035] On the left side of the left side plate frame 100, mounting seats one 300 are symmetrically arranged front and back. A first driving rod 310 is rotatably arranged between the two mounting seats one 300. A first worm gear 320 is arranged at the left end of each adjusting rod 210. A first worm 330 that meshes with the first worm gear 320 is arranged on the rod body of the first driving rod 310. Among them, the first worm gear 320 and the first worm 330 do not have self-locking property, that is, the first worm 330 can drive the first worm gear 320 to rotate, and the first worm gear 320 can also drive the first worm 330 to rotate;

[0036] On the right side of the right side plate frame 100, mounting seats two 400 are symmetrically arranged front and back. A second driving rod 410 is rotatably arranged between the two mounting seats two 400. A second worm gear 420 is arranged at the right end of each adjusting cylinder 240. A second worm 430 that meshes with the second worm gear 420 is arranged on the rod body of the second driving rod 410. Among them, the lead angle of the second worm 430 is smaller than the equivalent friction angle between the meshing teeth of the second worm gear 420, realizing reverse self-locking property, that is, only the second worm 430 can drive the second worm gear 420, and the second worm gear 420 cannot drive the second worm 430; when the adjusting rod 210 rotates, due to the self-locking property of the second worm gear 420 and the second worm 430 at the right end of the adjusting cylinder 240, the adjusting cylinder 240 cannot rotate, thereby adjusting the overall length of the adjusting rod 210 and the adjusting cylinder 240, that is, adjusting the distance between the first roller 220 and the second roller 250, so as to meet the conveying of fittings with different widths;

[0037] Further, universal wheels 110 are arranged at equal intervals at the bottom of each side plate frame 100. A brake pad for locking the wheels is arranged on each universal wheel 110. The whole device can be conveniently moved through the universal wheels 110. After the overall length of the telescopic roller 200 is adjusted, it is also convenient to adjust the distance between the two side plate frames 100.

[0038] Further, a second roller 250 protrudes from the right outer side of the rod body of the adjusting cylinder 240. The outer diameters of the second roller 250 and the first roller 220 are the same. The first roller 220 and the second roller 250 are in contact with the bottom of the fitting at the same time, making the conveying of the fitting more stable.

[0039] Further, transverse limiting grooves 260 are symmetrically formed in the front and rear of the inner side wall of the first roller 220. Limiting blocks 270 protrude from the front and rear side walls at the left end of the adjusting cylinder 240, and the limiting blocks 270 are slidably fitted in the grooves of the limiting grooves 260. When the adjusting cylinder 240 rotates, the first roller 220 rotates accordingly through the limiting blocks 270 and the limiting grooves 260, so as to convey the fitting, and the limiting blocks 270 and the limiting grooves 260 do not prevent the overall length adjustment of the adjusting rod 210 and the adjusting cylinder 240.

[0040] Further, the rod body of the adjusting rod 210 rotatably penetrates through the side wall of the left side plate frame 100 through a first bearing sleeve 280. The first bearing sleeve 280 reduces the friction between the adjusting rod 210 and the left side plate frame 100 when the adjusting rod 210 rotates; the rod body of the adjusting cylinder 240 rotatably penetrates through the side wall of the right side plate frame 100 through a second bearing sleeve 290. The second bearing sleeve 290 reduces the friction between the adjusting cylinder 240 and the right side plate frame 100 when the adjusting cylinder 240 rotates.

[0041] Further, a first protective shell 340 is fixedly arranged on the left side wall of the left side plate frame 100. The inner cavity of the first protective shell 340 houses and surrounds all the first mounting seats 300, the first worm wheels 320 and the first worms 330. The first protective shell 340 prevents the components from being directly exposed to the outside; a forward and reverse motor 350 is arranged at the front end of the first protective shell 340. The output shaft of the forward and reverse motor 350 rotatably penetrates through the first protective shell 340 and the first mounting seat 300 and is connected to the end of the first driving rod 310. After starting the forward and reverse motor 350, the first driving rod 310 is driven to rotate, and all the adjusting rods 210 are driven to rotate through the first worms 330 and the first worm wheels 320.

[0042] Further, a second protective shell 440 is fixedly arranged on the right side wall of the right side plate frame 100. The inner cavity of the second protective shell 440 houses and surrounds all the second mounting seats 400, the second worm wheels 420 and the second worms 430. The second protective shell 440 prevents the components from being directly exposed to the outside; a servo motor 450 is arranged at the front end of the second protective shell 440. The output shaft of the servo motor 450 rotatably penetrates through the second protective shell 440 and the second mounting seat 400 and is connected to the end of the second driving rod 410. After starting the servo motor 450, the second driving rod 410 is driven to rotate, and all the adjusting cylinders 240 are driven to rotate through the second worms 430 and the second worm wheels 420.

[0043] In the specific use process, place the fitting to be conveyed on the first roller 220 and the second roller 250. Start the servo motor 450 to drive the second driving rod 410 to rotate. Drive all the adjusting cylinders 240 and the second roller 250 to rotate through the second worm 430 and the second worm gear 420. Then, drive the first roller 220 to rotate through the limiting block 270 and the limiting groove 260, so as to convey the fitting.

[0044] When the overall width of the bottom of the fitting is greater than that of the current first roller 220 and the second roller 250, start the forward and reverse motor 350 to drive the first driving rod 310 to rotate. Drive all the adjusting rods 210 to rotate through the first worm 330 and the first worm gear 320. Since the second worm gear 420 and the second worm 430 at the right end of the adjusting cylinder 240 have self-locking properties, the adjusting cylinder 240 cannot rotate. Thus, adjust the overall length of the adjusting rod 210 and the adjusting cylinder 240, that is, adjust the distance between the first roller 220 and the second roller 250, so as to meet the conveying of fittings with different widths.

[0045] Although the present invention has been described with reference to the embodiments above, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments of the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
