[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a multi-stage screw sorting structure, which includes: A straightening assembly includes a guide frame and a first pusher. The guide frame has a straightening groove, and the first pusher is mounted at one end of the guide frame. Its pusher screw slides along the straightening groove and disengages from the straightening groove. A screening component includes a housing and a second pusher. The housing has a guide hole, a first receiving cavity, and a second receiving cavity. The top end of the guide hole receives a screw that falls from the straightening groove and is connected to the first receiving cavity. The ground of the first receiving cavity has a first notch and a second notch sequentially formed along a direction away from the guide hole. The inner diameter of the first notch is smaller than the inner diameter of the second notch. The second pusher is installed at the top end of the guide hole and pushes the screw in the guide hole into the first receiving cavity. The second receiving cavity is connected to the bottom end of the guide hole. The ground of the second receiving cavity has a third notch and a fourth notch sequentially formed along a direction away from the guide hole. The inner diameter of the third notch is smaller than the inner diameter of the fourth notch.

[0007] In some embodiments, the bottom end of the first accommodating cavity has an inclined first stepped surface, the first notch and the second notch are both formed on the lower side of the first stepped surface, and the first notch and the second notch are both adjacent to the junction of the first stepped surface.

[0008] In some embodiments, the screening component further includes a fourth pusher mounted on the first stepped surface, which pushes a screw on the first stepped surface toward the first notch and the second notch.

[0009] In some embodiments, the bottom end of the second accommodating cavity has an inclined second stepped surface, and the third notch and the fourth notch are both opened on the lower side of the second stepped surface, and the third notch and the fourth notch are both adjacent to the junction of the second stepped surface.

[0010] In some embodiments, the screening component further includes a fifth pusher mounted on the second stepped surface, which pushes the screws on the second stepped surface toward the third notch and the fourth notch.

[0011] In some embodiments, the housing is provided with a first storage slot, a second storage slot, a third storage slot and a fourth storage slot, and the first storage slot, the second storage slot, the third storage slot and the fourth storage slot are respectively disposed in the first notch, the second notch, the third notch and the fourth notch.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of simultaneously screening screws of different lengths and diameters, this invention provides a multi-stage screw sorting structure. This structure can simultaneously screen screws of different lengths and diameters, improving the screw sorting efficiency.

[0020] It should be noted that the multi-stage screw sorting structure of this utility model is used for screw sorting. For ease of explanation, this utility model will only be described in the context of the application of the multi-stage screw sorting structure to screw sorting.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of a screw multi-stage sorting structure in one embodiment of the present invention. The screw multi-stage sorting structure includes a straightening component 100 and a screening component 200. The straightening component 100 includes a guide frame 110 and a first pusher 120. The guide frame 110 has a straightening groove 111. The first pusher 120 is installed at one end of the guide frame 110 and pushes the screw to slide along the straightening groove 111 and disengage from the straightening groove 111. The screening component 200 includes a housing 210 and a second pusher 220. The housing 210 has a guide hole 211, a first receiving cavity 213 and a second receiving cavity 214. The top of the guide hole 211 receives a screw that falls from the regularization groove 111 and the top of the guide hole 211 is connected to the first receiving cavity 213. The ground of the first receiving cavity 213 has a first notch 2131 and a second notch 2132 sequentially formed along the direction away from the guide hole 211. The inner diameter of the first notch 2131 is smaller than the inner diameter of the second notch 2132. The second pusher 220 is installed at the top of the guide hole 211 and pushes the screw in the guide hole 211 into the first receiving cavity 213. The second receiving cavity 214 is connected to the bottom of the guide hole 211. The ground of the second receiving cavity 214 has a third notch 2141 and a fourth notch 2142 sequentially formed along the direction away from the guide hole 211. The inner diameter of the third notch 2141 is smaller than the inner diameter of the fourth notch 2142.

[0022] In this embodiment, the screws to be screened are first placed on the guide frame 110, with the screw shaft extending into the leveling groove 111 and the screw head remaining above the leveling groove 111, thus leveling the screw's position. Then, the first pusher 120 pushes the screw to move, allowing it to slide along the guide frame 110 and fall into the guide hole 211. Screws with larger diameters cannot pass through the guide hole 211; these screws enter the first receiving cavity 213 at the top of the guide hole 211. Screws with smaller lengths can fall directly into the first notch 2131, while larger screws pass through the first notch 2131 and eventually fall into the second notch 2132. Screws with smaller diameters pass through the guide hole 211, entering the second receiving cavity 214 at the bottom of the guide hole 211. Screws with smaller lengths can fall directly into the third notch 2141, while larger screws pass through the first notch 2131 and eventually fall into the fourth notch 2142. The multi-stage screw sorting structure described above can simultaneously screen screws of different lengths and diameters, thus improving the screw sorting efficiency.

[0023] In some embodiments, the bottom end of the first receiving cavity 213 has an inclined first stepped surface. The first notch 2131 and the second notch 2132 are both located on the lower side of the first stepped surface, and both are adjacent to the boundary of the first stepped surface. When a screw enters the first receiving cavity 213, the screw head presses against the higher side of the first stepped surface, while the screw shaft presses against the lower side. Longer screws, with a length greater than the inner diameter of the first notch 2131, can pass through the first notch 2131 and eventually fall into the second notch 2132. Shorter screws, with a length less than the inner diameter of the first notch 2131, fall directly into the first notch 2131.

[0024] Based on the above embodiments, in some embodiments, the screening component 200 further includes a fourth pusher 240, which is mounted on the first stepped surface and pushes the screw on the first stepped surface toward the first notch 2131 and the second notch 2132. Under the push of the fourth pusher 240, the screw slides along the first stepped surface.

[0025] In some embodiments, the bottom end of the second accommodating cavity 214 has an inclined second stepped surface. The third notch 2141 and the fourth notch 2142 are both located on the lower side of the second stepped surface, and both are adjacent to the boundary of the second stepped surface. When a screw enters the second accommodating cavity 214, the screw head presses against the higher side of the second stepped surface, while the screw shaft presses against the lower side. Longer screws, with a length greater than the inner diameter of the third notch 2141, can pass through the third notch 2141 and eventually fall into the fourth notch 2142. Shorter screws, with a length less than the inner diameter of the third notch 2141, fall directly into the third notch 2141.

[0026] Based on the above embodiments, in some embodiments, the screening component 200 further includes a fifth pusher 250, which is mounted on the second stepped surface and pushes the screw on the second stepped surface toward the third notch 2141 and the fourth notch 2142. Under the push of the fifth pusher 250, the screw slides along the second stepped surface.

[0027] In some embodiments, the housing 210 has a first storage slot 215, a second storage slot 216, a third storage slot 217, and a fourth storage slot 218. These slots are correspondingly located in the first notch 2131, the second notch 2132, the third notch 2141, and the fourth notch 2142. Screws that fall into these notches will then enter the first storage slot 215, the second storage slot 216, the third storage slot 217, and the fourth storage slot 218, respectively.

[0028] Based on the above embodiments, in some embodiments, the screening component 200 further includes four collection boxes 260, which are embedded in the first storage slot 215, the second storage slot 216, the third storage slot 217 and the fourth storage slot 218 respectively.

[0029] In some embodiments, a base 219 is formed at the bottom of the housing 210 to support the screw multi-stage sorting structure.

[0030] Furthermore, this utility model also provides a screw screening device, which includes several of the aforementioned multi-stage screw sorting structures, multiple guide frames 110 stacked vertically, and multiple regular grooves 111 whose widths gradually narrow vertically. It is understood that each multi-stage screw sorting structure can screen two screw diameters, while using multiple nested multi-stage screw sorting structures allows for the screening of screws of various diameters at each stage, thus expanding the screw screening range.

[0031] In some embodiments, the screw screening equipment further includes a feeding structure A, which includes a feeding box 310, a feeding pusher plate 320, and a feeding drive component 330. The feeding box 310 is abutted against the guide frame 110 located at the top, and the bottom of the feeding box 310 is inclined towards the guide frame 110. The feeding pusher plate 320 is slidably disposed on the side wall of the feeding box 310 near the guide frame 110, and the feeding pusher plate 320 has a first position near the bottom surface of the feeding box 310 and a second position near the top surface of the feeding box 310. The feeding drive component 330 is throttle-connected to the feeding pusher plate 320, and drives the feeding pusher plate 320 to move between the first position and the second position. Screws to be screened can be placed in the feeding box 310. Since the bottom of the feeding box 310 is inclined towards the guide frame 110, the screws accumulate on the feeding pusher plate 320. As the feeding pusher plate 320 moves continuously, the screws in the feeding box 310 are gradually pushed towards the box guide frame 110.

[0032] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: First, the screws to be screened are placed on the guide frame 110, with the screw shaft extending into the leveling groove 111 and the screw head remaining above the leveling groove 111, thus leveling the screw's position. Then, the first pusher 120 pushes the screw to move, allowing it to slide along the guide frame 110 and fall into the guide hole 211. Screws with larger diameters cannot pass through the guide hole 211; these screws enter the first receiving cavity 213 at the top of the guide hole 211. Screws with smaller lengths can fall directly into the first notch 2131, while larger screws pass through the first notch 2131 and eventually fall into the second notch 2132. Screws with smaller diameters pass through the guide hole 211, entering the second receiving cavity 214 at the bottom of the guide hole 211. Screws with smaller lengths can fall directly into the third notch 2141, while larger screws pass through the first notch 2131 and eventually fall into the fourth notch 2142. The multi-stage screw sorting structure described above can simultaneously screen screws of different lengths and diameters, thus improving the screw sorting efficiency.
