Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building material pin and pin piece sorting equipment, and in particular to an automatic sorting equipment for building material pins and pin pieces. Background Technology
[0002] In the current construction industry, aluminum alloy formwork is seeing a continuous increase in usage due to its significant advantages such as short construction cycles, lightweight and quick operation, and energy conservation and environmental friendliness. As the main connecting components of aluminum formwork, pins and pin plates play an indispensable role, and their usage is extremely large. In particular, the reusable nature of pins and pin plates aligns with the construction industry's concepts of cost reduction, efficiency improvement, and green development.
[0003] However, in actual construction sites, after use, the pins and pin plates are covered with concrete and rust, and these impurities must be removed before reuse. Separating the pins, pin plates, and other components during mixed recycling and refurbishment becomes a challenging problem. The separation process relies heavily on manual labor, which is not only costly but also extremely inefficient. This situation severely restricts the efficient recycling of pins and pin plates and increases the overall cost of aluminum formwork production.
[0004] In the current production process, pins and pin pieces are refurbished by shot blasting and then packaged. They are then sorted and packaged by on-site workers. Manual sorting of pins and pin pieces requires a lot of time and effort. Workers are prone to fatigue under long hours of repetitive labor, which leads to slow sorting speed.
[0005] Therefore, there is an urgent need to design an automatic sorting device for pins and pin pieces, which is of great significance for improving sorting efficiency and reducing labor costs. Utility Model Content
[0006] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, this utility model provides an automatic sorting device for building material pins and pin pieces.
[0007] Its technical solution includes a main support system, a feeding and discharging system, a material screening system, and a power system;
[0008] The main support system includes a housing, support legs, side braces, and springs;
[0009] The feeding and discharging system includes a feeding port and a discharging mechanism;
[0010] The material screening system includes a right-angle groove, an upper sieve plate, and a lower sieve plate;
[0011] The power system includes two vibration motors.
[0012] The box body includes a bottom plate and a U-shaped baffle set around the bottom plate. Triangular baffles are fixedly set at the bottom of the two opposite side plates of the U-shaped baffle, and an inclined plate is set between the two triangular baffles. The two vibration motors are fixedly set on the outer wall of the inclined plate.
[0013] The lower sieve plate and the upper sieve plate are arranged sequentially from bottom to top above the base plate;
[0014] The lower sieve plate and the upper sieve plate are arranged alternately. The inner wall of the U-shaped baffle is provided with two sets of support frames, each set of support frames including a right-angle groove fixedly arranged on the inner wall of the U-shaped baffle. The two ends of the lower sieve plate and the upper sieve plate are respectively fixed on the right-angle groove.
[0015] The space above the upper screen plate is the first screening space, the space between the upper screen plate and the lower screen plate is the second screening space, and the space between the lower screen plate and the bottom plate is the third screening space.
[0016] The feed inlet is fixedly installed on the top of one end of the box body;
[0017] The discharge mechanism is located at the other end of the box;
[0018] The discharge mechanism is set as a stepped sorting channel, and the discharge mechanism includes a first discharge frame, a second discharge frame, and a third discharge frame.
[0019] The first discharge frame is located at one end of the first screening space, and the outermost end of the first discharge frame is provided with the first discharge port; the second discharge frame is located at one end of the second screening space, and the outermost end of the second discharge frame is provided with the second discharge port; the third discharge frame is located at one end of the third screening space, and the outermost end of the third discharge frame is provided with the third discharge port.
[0020] The width of the second-layer discharge frame is smaller than the width of the first-layer discharge frame; the width of the third-layer discharge frame is smaller than the width of the second-layer discharge frame, forming a stepped sorting channel.
[0021] Inclined guide plates are provided at the first, second, and third discharge outlets;
[0022] The outlets of the first, second, and third discharge layers are staggered.
[0023] The U-shaped baffle is symmetrically provided with fixed seats on both sides. The spring is provided between the bottom of the fixed seat and the top of the support leg. The upper and lower ends of the spring are fixedly connected to the bottom of the fixed seat and the top of the support leg, respectively.
[0024] Adjacent support legs are fixedly connected by the side braces.
[0025] The size of the sieve holes on the upper sieve plate is larger than that on the lower sieve plate.
[0026] In the first screening space, large parts such as nuts cannot pass through the screen holes on the upper screen plate and move along the screen surface of the upper screen plate to the first discharge port, i.e. the large parts discharge port.
[0027] In the secondary screening, i.e. the second screening space, the pins and pin pieces fall into the second screening space through the upper screen plate. The pins, because their diameter is larger than the screen holes of the lower screen plate, continue to be conveyed forward and move along the screen surface of the lower screen plate to the second discharge port.
[0028] In the third-level screening space, the pins fall through the screen holes of the lower screen plate into the bottom layer, the third screening space, and are finally discharged from the third discharge port, the small parts discharge port.
[0029] The main structure of this system is welded from steel, including the discharge mechanism, feed inlet, upper screen plate, lower screen plate, housing, support legs, springs, etc., with the power system provided by two vibrating motors. Sorting is completed using mechanical vibration and gravity guidance. Mechanical vibration causes the material to be thrown across the screen surface; adjusting the screen aperture size allows for the separation of materials of different sizes or shapes. The upper and lower double-layer screen plate design enables the separation of various materials.
[0030] The beneficial effects of the technical solution provided by this utility model embodiment are:
[0031] (1) The equipment has a simple structure and is mainly made of welded steel, resulting in low manufacturing and maintenance costs; it has a compact design, strong practicality, and small footprint, making it easy to arrange in a limited space; and its maintenance and operation are simple and inexpensive.
[0032] (2) The equipment adopts a double-layer screen plate structure. The core structure is welded from steel, and the mechanical structure is durable. It relies on mechanical vibration and gravity guidance to complete the sorting of pins and pin pieces, which significantly reduces the equipment manufacturing cost and failure risk. Compared with traditional manual sorting, its sorting efficiency is greatly improved, its economic benefits are more prominent, and at the same time, it significantly reduces the sorting error rate and improves the production quality.
[0033] (3) Traditional manual sorting relies on workers to visually screen and manually classify, which is inefficient and easy to get tired. This equipment simplifies the role of workers to feeding and collecting materials, greatly reducing physical load and avoiding occupational health problems caused by long-term repetitive labor. At the same time, the equipment can replace multiple sorting workers, significantly saving labor costs. Attached Figure Description

[0057] A feed inlet 1 is fixedly installed on the top of one end of the housing 9;
[0058] The discharge mechanism is located at the other end of the housing 9;
[0059] The discharge mechanism is set as a stepped sorting channel, and the discharge mechanism includes a first discharge frame, a second discharge frame, and a third discharge frame.

The pins, because their diameter is larger than the screen holes of the lower screen plate 4, continue to be conveyed forward and move along the screen surface of the lower screen plate 4 to the second discharge port 202.

[0070] The main structure of this system is welded from steel, including the discharge mechanism, feed inlet, upper screen plate, lower screen plate, housing, support legs, springs, etc., with the power system provided by two vibrating motors. Sorting is completed using mechanical vibration and gravity guidance. Mechanical vibration causes the material to be thrown across the screen surface; adjusting the screen aperture size allows for the separation of materials of different sizes or shapes. The upper and lower double-layer screen plate design enables the separation of various materials.
[0071] When using this solution, the following steps are included:
[0072] S1. Manual feeding: The operator feeds the mixed materials into the system through inlet 1;
[0073] S2. Vibration Conveying: After the vibration motor 8 starts, it generates directional excitation force, driving the material to move in a parabolic motion along the screen surface and conveying it forward.
[0074] S3, Tiered Screening:
[0075] In the first screening space, large parts such as nuts cannot pass through the screen holes on the upper screen plate 3 and move along the screen surface of the upper screen plate 3 to the first discharge port 201, i.e., the large part discharge port.
[0076] In the secondary screening, i.e. the second screening space, the pins and pin pieces fall into the second screening space through the upper screen plate 3. The pins, because their diameter is larger than the screen holes of the lower screen plate 4, continue to be conveyed forward and move along the screen surface of the lower screen plate 4 to the second discharge port 202, i.e. the medium part discharge port, and are discharged.
[0077] In the third-level screening space, the pins fall through the screen holes of the lower screen plate 4 into the bottom layer, i.e., the third-level screening space, and are finally discharged from the third-level discharge port 203, i.e. the small parts discharge port.
[0078] S4. Sorting and Collection: The three types of materials are sorted through three independent channels at the end: the first discharge port 201, the second discharge port 202, and the third discharge port 203.
[0079] This solution utilizes mechanical structure design, physical sorting principles, and the characteristics of a vibrating motor to achieve the sorting of pins and pin plates. In the construction industry, pins and pin plates are core components for connecting aluminum formwork. Due to their diverse specifications and similar shapes, such as cylindrical pins and flat pin plates, traditional sorting relies heavily on manual visual screening and classification. This method is not only inefficient and labor-intensive, but also prone to sorting errors due to worker fatigue or subjective mistakes, thus affecting construction quality. Furthermore, it faces the dual pressures of labor shortages and rising labor costs. To address these issues, this solution proposes an automatic pin and pin plate sorting device based on a vibrating screen. Its simple and efficient design achieves automatic sorting, breaking through the limitations of traditional methods and comprehensively improving sorting efficiency and reliability. The core design concept of this equipment is to simplify the structure and principle, ensuring easy implementation and low maintenance. A vibrating motor drives the screen body to generate directional vibration. Utilizing the difference in the motion trajectory of cylindrical pins and flat pin plates during vibration, combined with the progressively decreasing width of the stepped sorting channel and the progressively decreasing screen aperture, the two are separated. After sorting, the parts slide into the corresponding collection bins via inclined guide plates. The entire process requires no complex sensors or control systems, relying solely on mechanical vibration and gravity guidance to complete the sorting, which significantly reduces equipment manufacturing costs and failure risks.
[0080] Compared to manual sorting, this equipment can operate continuously for 24 hours, with a single machine processing capacity of up to 2000 pieces / hour, increasing efficiency by more than 5 times, and achieving a sorting error rate of less than 0.5%, completely avoiding material mixing problems caused by human error. Furthermore, while improving efficiency, it also considers occupational health and economic benefits. Traditional manual sorting requires workers to perform repetitive, high-intensity actions such as bending over, grabbing, and visually checking for extended periods, easily leading to muscle strain, spinal diseases, and visual fatigue. This equipment simplifies the worker's role to simply feeding and collecting materials, significantly reducing physical burden. From a cost perspective, a single machine can replace 3-4 sorting workers, saving over 150,000 yuan in labor costs annually. Its robust mechanical structure and low maintenance costs eliminate the need for frequent replacement of high-value electrical control components and easily worn parts, providing long-term support for cost reduction and efficiency improvement for enterprises. It systematically solves the efficiency, quality, health, and cost issues related to the sorting of pins and clips in the aluminum formwork production and renovation process.
[0081] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
