Description

Technical Field

[0001] This utility model relates to the technical field of button sorting equipment, and more specifically, to a thickness sorting equipment for metal buttons. Background Technology

[0002] With the rise of fast fashion, buttons have transformed from functional items to creative ones, becoming clothing decorations and more.

[0003] A search revealed that patent publication number CN218982354U discloses a button thickness sorting device, which solves the problems of current sorting devices, most of which rely on manual picking and cannot efficiently sort buttons of different thicknesses using a double-roller sorting method, resulting in time-consuming, labor-intensive, and inefficient processes. The device includes a frame with a controller fixedly connected to its front, a drawer fixedly connected to its bottom, and a fixed frame fixedly connected to its left side. The inner cavity of the fixed frame houses a sorting mechanism that works in conjunction with the frame. This sorting mechanism categorizes buttons into thin, medium, and thick types, achieving efficient sorting of buttons of different thicknesses using a double-roller sorting method, saving time and labor while increasing efficiency. A guiding mechanism further assists in guiding the buttons of different thicknesses during the feeding process, preventing them from sticking to the hopper walls and clogging, thus facilitating the button sorting work. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Most existing metal buttons are flat and tend to stack together due to gravity during the sorting process. The total thickness of the stacked buttons exceeds the gap size, and they will get stuck between the two rollers when rotating relative to each other. If the edges of the buttons have burrs or irregular shapes, they are more likely to hook together after stacking, increasing the risk of jamming. Metal buttons generate debris, impurities and dust during processing. Some fine particles will adhere to the button surface or enter the sorting equipment with the material. Over time, the dust accumulated on the roller surface will increase the actual sorting gap, affect the sorting quality, and easily cause button blockage.

[0005] Therefore, a thickness sorting device for metal buttons is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a thickness sorting device for metal buttons to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a thickness sorting device for metal buttons, comprising a workbench, a vibrating frame, an inclined multi-stage guide hopper, and an airflow nozzle. A load-bearing pile is provided on the upper left side of the workbench, and a feed hopper is installed at the center of the load-bearing pile. The vibrating frame is located at the upper end of the workbench, and the inclined multi-stage guide hopper is located in the inner cavity of the vibrating frame.

An air delivery pipe is installed at the output end of the air pump. A fixing air pipe is installed at the bottom of the upper end of the fixing frame. The airflow nozzle is located at the bottom of the fixing air pipe.

[0009] Preferably, the inclined multi-stage guide hopper is provided in three sets, and the three sets of inclined multi-stage guide hoppers are distributed adjacently in a stepped manner.

[0010] Preferably, the inclination angles of the three sets of inclined multi-stage guide hoppers and the three sets of sorting ports are in the same direction, and the shape and size of the three sets of sorting ports gradually increase from small to large.

[0011] Preferably, the end of the rubber spring away from the vibration frame is fixedly connected to the worktable, and an opening is provided at the center of the worktable.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] As attached Figures 1 to 4The metal button thickness sorting device shown includes a workbench 1, a vibrating frame 4, an inclined multi-stage guide hopper 5, and an airflow nozzle 10. A load-bearing pile 2 is provided on the upper left side of the workbench 1, providing a stable bearing foundation for the device. The load-bearing pile 2 independently supports the feed hopper 3 and the weight of the material. The feed hopper 3 is installed at the center of the load-bearing pile 2, and the feed hopper 3 guides the buttons to fall evenly into the vibrating frame 4. The vibrating frame 4 is located at the upper end of the workbench 1, and the vibration of the vibrating frame 4 by the vibration of the vibrating motor 6 provides conditions for grading. The inclined multi-stage guide hopper 5 is located in the inner cavity of the vibrating frame 4, and a sorting port 51 is opened at the bottom of the inclined multi-stage guide hopper 5. The inclined multi-stage guide hopper 5 and the sorting port 51 use inclined channels and outlets of different sizes to achieve button thickness sorting.

[0026] Vibration motors 6 are installed at both the front and rear ends of the vibration frame 4. The vibration motors 6 provide vibration energy. Rubber springs 41 are installed at the four corners of the bottom of the vibration frame 4. The rubber springs 41 can help the vibration frame 4 to vibrate at high frequency on the worktable 1 through the elastic potential energy of their own structure. A fixed frame 7 is welded to the rear of the upper end of the vibration frame 4. The fixed frame 7 securely installs the airflow system components to ensure the precise position of the airflow nozzle 10. Air pumps 8 are installed on both sides of the upper end of the fixed frame 7. An air delivery pipe 11 is installed at the output end of the air pump 8. A fixed air pipe 9 is installed at the bottom of the upper end of the fixed frame 7. The air pump 8, the air delivery pipe 11, and the fixed air pipe 9 provide a stable high-pressure airflow to ensure uniform purging pressure. The airflow nozzle 10 is located at the bottom of the fixed air pipe 9. The airflow nozzle 10 removes impurities in the inclined multi-stage guide hopper 5 and assists in material flow to maintain the accuracy of the sorting port 51. Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0028] In a preferred embodiment, three sets of inclined multi-stage guide hoppers 5 are provided, which are arranged adjacently in a stepped manner. The three sets of inclined multi-stage guide hoppers 5 are arranged in a stepped manner, and the height difference forms a gravity-driven material flow path, so that the buttons slide down the inclined multi-stage guide hoppers 5 step by step. The inclination angle of the three sets of inclined multi-stage guide hoppers 5 and the three sorting ports 51 is in the same direction. The shape and size of the three sorting ports 51 increase step by step from large to small, which can meet the grading requirements of buttons in different thickness ranges. The buttons pass through in order from large to small, so as to achieve multi-level precise sorting and avoid mixing of products of different thicknesses.

[0029] In a preferred embodiment, the end of the rubber spring 41 away from the vibration frame 4 is fixedly connected to the workbench 1. The elastic potential energy of the rubber spring 41 can help the vibration frame 4 to vibrate at high frequency on the workbench 1. An opening 101 is provided at the center of the workbench 1, which provides a vertical falling channel for the sorted buttons.

[0030] In a preferred embodiment, the ends of the two sets of air supply pipes 11 away from the air pump 8 are respectively connected to the two ends of the fixed air pipe 9. The ends of the two sets of air supply pipes 11 away from the air pump 8 are respectively connected to the two ends of the fixed air pipe 9. By supplying air to both ends simultaneously, the air pressure distribution in the fixed air pipe 9 can be made more uniform, avoiding the problem of air pressure attenuation at the far end caused by single-end air supply. Several sets of airflow nozzles 10 are provided, and the several sets of airflow nozzles 10 are distributed at equal intervals. The airflow nozzles 10 are inclined towards the side closer to the sorting port 51. The equally spaced and inclined airflow nozzles 10 can form a continuous airflow purging surface above the inclined multi-stage guide hopper 5.

[0031] In a preferred embodiment, the bottom of the feed hopper 3 extends above one of the sets of inclined multi-stage guide hoppers 5. This allows the button to fall directly and accurately into the starting end of the corresponding set of inclined multi-stage guide hoppers 5 when it falls from the feed hopper 3. Support legs 14 are welded at the four corners of the bottom of the workbench 1.

[0032] In a preferred embodiment, a storage cart 12 is provided below the opening 101. The storage cart 12 allows the sorted buttons to fall directly into the storage cart 12 through the opening 101. The inner cavity of the storage cart 12 is welded with partitions 13, and two sets of partitions 13 are provided. The inner cavity of the storage cart 12 is divided into three spaces by the two sets of partitions 13. The two sets of partitions 13 welded to the inner cavity of the storage cart 12 and divided into three spaces correspond one-to-one with the grading results of the three sorting ports 51, so that each space collects buttons of different thicknesses.

[0033] The working process of this utility model is as follows: First, the metal buttons are loaded by the feeding hopper 3, whose bottom extends above a set of inclined multi-stage guide hoppers 5 inside the vibrating frame 4. Stable feeding is achieved under the independent support of the load-bearing piles 2. The buttons fall directly into the starting end of the corresponding inclined multi-stage guide hopper 5 through the outlet of the feeding hopper 3. The workbench 1 provides a horizontal bearing foundation for the entire system, and the support legs 14 at the four corners of the bottom ensure the stability of the equipment. The vibrating frame 4 is elastically connected to the workbench 1 through rubber springs 41 at the four corners of the bottom. The vibration motors 6 at the front and rear ends generate directional excitation force through the rotation of eccentric blocks, driving the vibrating frame 4 to vibrate at high frequency. The kinetic energy is buffered by the rubber spring 41, which reduces the excessive shaking of the worktable 1. At the same time, the buttons on the surface of the inclined multi-stage guide hopper 5 slip and bounce loosely due to inertia, and slide down the inclined surface in a loose state. The three sets of inclined multi-stage guide hoppers 5 are distributed in a stepped manner. The height difference forms gravity assistance, and the buttons are guided to move along a uniform trajectory at the same inclination angle. The three sorting ports 51 at the bottom increase in size from large to small. Thin buttons pass through the upper small sorting port 51 first, medium buttons are screened through the middle sorting port 51, and the lower large sorting port 51 is used to sort thick buttons to achieve thickness grading.

[0034] The fixed frame 7 is welded to the upper rear of the vibrating frame 4, providing stable support for the air pumps 8 on both sides. The air pumps 8 supply air to the fixed air pipe 9 from both ends through the air supply pipe 11, ensuring uniform air pressure inside the pipe. The airflow nozzles 10, which are evenly spaced and inclined at the bottom, spray high-pressure airflow towards the sorting port 51, blowing away impurities and dust from the inner wall of the inclined multi-stage guide hopper 5 and the edge of the sorting port 51 in real time. At the same time, they provide a unidirectional boosting force to the sliding buttons. The sorted buttons fall vertically through the opening 101 in the center of the workbench 1 and into the storage cart 12 below. The two sets of welded partitions 13 inside the storage cart 12 divide the inner cavity into three spaces, which correspond to the grading results of the three sorting ports 51, so that buttons of different thicknesses fall accurately into their respective areas, completing automated classification and collection, and achieving efficient and accurate thickness sorting. The above is the working principle of this metal button thickness sorting equipment.
