Description

Technical Field

[0001] This utility model mainly relates to the field of screw processing technology, specifically to a screw production screening device. Background Technology

[0002] As a crucial fastening component in industry, the screening process during screw production is vital to product quality. Current screw screening equipment often employs an open or semi-enclosed design, resulting in the screening mechanism being exposed to the external environment for extended periods, leading to the following technical drawbacks:

[0003] Traditional screening equipment lacks effective sealing for key components such as the sorting track, allowing dust, oil, and other contaminants in the production workshop to easily penetrate the equipment, causing screw surface contamination and affecting subsequent processing or assembly quality. At the same time, the exposed mechanical structure is prone to contact with metal debris in the production workshop after long-term use, accelerating component wear and increasing maintenance frequency and costs. Based on these issues, a screw production screening device is proposed. Utility Model Content

[0034] It should be noted that the structures not described in this utility model do not involve the design points and improvement directions of this utility model and all adopt existing technology. At the same time, the content in the above background technology is within the technical knowledge scope of the utility model user. Since the technical content in this field is vast and too complex, the above content of this application does not necessarily constitute prior art. In addition, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Reference Figure 1-7 This embodiment provides a screw production screening device, including a sealed body 1. A feeding barrel 2 is provided on the top surface of one end of the body 1 and communicates with it. A sorting component 3 is provided inside the body 1 on the bottom surface of the feeding barrel 2. A collection box 4 is provided inside the body 1 on the bottom surface of the sorting component 3.

[0036] This embodiment provides a screw screening device that combines high-efficiency sorting with fully enclosed protection to solve the contamination problem caused by exposed screening structure in the prior art, while improving equipment reliability and product yield.

[0037] In a preferred embodiment, the sorting component 3 includes a sorting frame 31 disposed within the body 1. The outer ring of the sorting frame 31 is provided with multiple sets of pressure blocks 32. Each set of pressure blocks 32 is connected to a bracket 34 disposed on the bottom surface of the inner wall of the body 1 via a spring 33.

[0038] The sorting frame 31 is provided with a mounting plate 35 at one end, and a vibration motor 36 is provided inside the mounting plate 35. The output end of the vibration motor 36 passes through the mounting plate 35 and is provided with an eccentric wheel 37.

[0039] The sorting frame 31 is provided with sorting plate 1 38 and sorting plate 2 39 in a top-to-bottom direction. The sorting plate 1 38 and sorting plate 2 39 are respectively provided with a plurality of sorting holes 1 and sorting holes 2, and the diameter of sorting hole 1 is larger than the diameter of sorting hole 2.

[0040] As the vibrating motor 36 drives the eccentric wheel 37 to rotate, the center of gravity changes and causes swaying, which causes the sorting frame 31 to vibrate under the action of the spring 33, so that the screws that enter the surface of the sorting plate 38 are vibrated and screened.

[0041] In a more preferred embodiment, the first sorting hole and the second sorting hole are arranged in a trapezoidal shape from top to bottom to prevent the screws from getting clogged during the screening process.

[0042] In a preferred embodiment, both the sorting plate 38 and the sorting plate 39 are inclined.

[0043] In a preferred embodiment, the inner rings of multiple sets of brackets 34 are provided with a collection box 4 that slides on the bottom surface of the inner wall of the machine body 1, and the collection box 4 recycles the sorted screws.

[0044] In a preferred embodiment, the collection box 4 is divided into a collection trough 41 for collecting the smallest size screws, a collection trough 42 for collecting medium size screws, and a collection trough 43 for collecting the largest size screws by two sets of partitions 5. Screws that pass through the sorting hole 2 enter the collection trough 41 for collection.

[0045] In a preferred embodiment, the end of the sorting plate 38 is provided with a guide plate 6, which guides the sorted screws into the collection trough 43.

[0046] In a preferred embodiment, the end of the sorting plate 39 is provided with a guide plate 7, which guides the sorted screws into the collection trough 42.

[0047] In a preferred embodiment, the top surface of the feed hopper 2 is provided with a cover 21, wherein the method of opening the cover 21 is not specifically limited, and it can be opened by a cylinder or manually, preferably by a cylinder.

[0048] In a preferred embodiment, an observation window 22 is provided on one side of the feeding barrel 2 to facilitate observation of the screw feeding situation inside the feeding barrel 2. The bottom surface of the feeding barrel 2 is provided with a discharge port, which, under the action of the guide plate, transports the screws to the beginning of the sorting plate 38.

[0049] In a preferred embodiment, both the sorting plate 38 and the sorting plate 39 can be detachably installed within the sorting frame 31. Preferably, the sorting plate 38 and the sorting plate 39 are installed within the sorting frame 31 using a snap-fit ​​method, which facilitates quick replacement of the sorting plate 38 and the sorting plate 39 according to the screw screening diameter requirements.

[0050] Working process: Open the feed hopper 2, place the screws inside the feed hopper 2, and the vibration motor 36 drives the eccentric wheel 37 to rotate. Due to the change in the center of gravity, the swaying occurs, causing the sorting frame 31 to vibrate under the action of the spring 33. This causes the screws entering the surface of the sorting plate 1 38 to be vibrated and screened. Screws that pass through the sorting hole 1 enter the sorting plate 2 39 for further screening. Screws that do not pass through the sorting hole 1 are transported to the corresponding collection trough 3 43 for collection through the guide plate 1 6. Screws that pass through the sorting hole 2 enter the collection trough 1 61 for collection. Screws that do not pass through the sorting hole 2 are transported to the corresponding collection trough 2 62 for collection through the guide plate 2 7. This achieves the sorting and classification of different screws.

[0051] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
