In one embodiment, for the above spacer assembly 3, the spacer assembly 3 includes a mounting frame 301 disposed on a top portion of one side of the supporting base 1, two sides of a top portion of the mounting frame 301 are each provided with a mounting baffle 302, two side guide plates 303 are disposed on a bottom portion of the mounting baffle 302, a top guide plate 304 is disposed between top portions of the two side guide plates 303, one end of the top guide plate 304 away from the supporting base 1 is provided with a flow stopping piston 305, a transmission box 306 is disposed between top portions of the two mounting baffle 302, a transmission mechanism 307 is disposed inside the transmission box 306, an opening 308 is disposed at a middle position of a bottom portion of the side guide plate 303, the transmission mechanism 307 includes sliding grooves 3071 disposed on two sides of the bottom portion of the transmission box 306, a driving gear 3072 is disposed on the top portion inside the sliding groove 3071, a connecting gear 3073 is disposed inside the driving gear 3072, and a linkage connecting rod 3074 is disposed on top and bottom portions of the driving gear 3072 and the connecting gear 3073 which are located on the same side, two connecting gears 3073 are provided with rotation connecting rods 3075 at the top and bottom, wherein the middle position of the rotation connecting rod 3075 at the bottom is fixed at the bottom of the transmission box 306, the bottom of the driving gear 3072 is connected with a guide wheel 3076 through a rotating shaft, one of the driving gears 3072 is sleeved with a clamping connecting piece 3077, a spacing threaded rod 3078 is arranged outside the clamping connecting piece 3077, the spacing threaded rod 3078 penetrates through the transmission box 306 and is connected with a spacing handle 3079, the top of one of the driving gears 3072 penetrates through the transmission box 306 and is connected with a spacing driving motor 30710, the mounting frame 301 is of a U-shaped structure, the rotation connecting rod 3075 and the connecting gear 3073 are movably connected, the linkage connecting rod 3074 and the connecting gear 3073 and the driving gear 3072 are movably connected, the spacing threaded rod 3078 and the clamping connecting piece 3077 are movably connected, and the spacing threaded rod 3078 and the side wall of the transmission box 306 are connected through threads, so that the rotation of the spacing handle 3079 can be manually adjusted, the relative movement of the two driving gears 3072 is realized to realize position adjustment, so that the width adjustment of the two guide wheels 3076 is driven, and the adaptation of bottle caps with different specifications is met; and the bottle cap is driven by an interval driving motor 30710 to rotate, and local positioning and directional transmission of the bottle cap are realized by matching the side guide plates 303 and the top guide plates 304 at the two sides. The working principle of the spacing component 3 is as follows: the side guide plate 303 is connected to a track for conveying external bottle caps, and performs interval adjustment and centering on the bottle caps entering the screening machine. The bottle caps are limited by the side guide plates 303 and the top guide plate 304 on the two sides of the bottle caps and flow inwards in sequence until the bottle caps contact the guide wheels 3076, the guide wheels 3076 are driven by the interval driving motor 30710 to rotate at a constant speed, the bottle caps are clamped by the grooves outside the guide wheels 3076 and are sequentially transferred to the rear of the channel to enter the first conveyor belt 5.
