Description

Technical Field

[0001] The utility model relates to the technical field of button screening, in particular to a button screening device. Background Art

[0002] Buttons, as indispensable components on products such as clothing and luggage, not only have the practical functions of connection and closure, but also often become key elements to enhance the aesthetic and fashion sense of products due to their diverse materials, colors and designs. Since buttons with different sizes and shapes will inevitably be produced during the production process, in order to ensure product quality, precise screening of buttons is required, so a button screening device is needed.

[0003] The traditional button screening method is relatively simple and direct. Usually, workers pour buttons onto a workbench with a sieve. The sieve is composed of grids with different pore sizes corresponding to the sizes of different specifications of buttons. The operator shakes the workbench continuously to make the buttons roll and move on the sieve, hoping that the buttons can pass through the sieve holes matching their sizes, so as to achieve screening. The efficiency of manual operation is extremely low. Relying on manual shaking of the workbench, the number of buttons processed each time is limited, making it difficult to meet the needs of large-scale production.

[0004] The prior art uses a push rod in cooperation with a screening machine and sieves with different sizes to screen buttons. The specific operation process is as follows: Place the buttons to be screened at the feed inlet of the screening machine, and push the buttons towards sieves with different pore sizes through the push rod. The sieves move reciprocally driven by a motor to make the buttons move on the sieves and try to pass through the sieve holes, so as to achieve the screening of buttons by size. In the actual use process, there are still problems with this improved method. Since most buttons are oblate, their shapes make it difficult to align precisely with the sieve holes when moving on the sieve. The rolling direction and angle of the buttons on the sieve are random. Often, the buttons contact the sieve holes at non-ideal angles and cannot pass through smoothly, and it is only possible to pass through the sieve holes after multiple rolling adjustments.

[0033] Refer to Figure 3 、 Figure 4 and Figure 6, an embodiment provided by the utility model: a button screening device, including a screening frame 1 and a support frame 4. Roller wheels 3 are fixedly connected to the four peripheries of the bottom of the screening frame 1, enabling the screening frame 1 to move on the support frame 4. Sliding grooves 5 are respectively opened on the front and rear sides of the top of the support frame 4, which cooperate with the roller wheels 3 to provide a track for the movement of the screening frame 1. Multiple roller wheels 3 are respectively slidably connected to the corresponding sliding grooves 5. Limiting grooves 6 are respectively opened on the upper and lower sides of the inner wall of the screening frame 1 for installing and positioning the corrugated plates 7. Multiple corrugated plates 7 are slidably connected to the inner walls of the multiple limiting grooves 6. Buttons are screened through the screening holes 8 opened on their tops. Multiple screening holes 8 are opened on the tops of the multiple corrugated plates 7 to screen the buttons according to the aperture size. Multiple retaining bars 9 are respectively arranged on the left and right sides of the tops of the multiple corrugated plates 7 to prevent a large accumulation of buttons during the screening process and make the distribution of buttons more uniform. The front and rear ends of the multiple retaining bars 9 are fixedly connected to the inner wall of the screening frame 1 to ensure the stability of the retaining bars 9 during the screening process. Multiple discharge plates 10 are fixedly connected to the front side of the right end of the outer wall of the screening frame 1 to guide the screened buttons to different storage positions. A fixed seat 11 is fixedly connected to the left side of the support frame 4 to provide an installation position for the motor 12. The motor 12 is fixedly connected to the top of the fixed seat 11 to provide power for the entire screening device. The output end of the motor 12 is fixedly connected to a rotating disk 13, which rotates under the drive of the motor 12 and then transmits power. A rocker 14 is rotatably connected to the top of the front side of the outer wall of the rotating disk 13. The right end of the rocker 14 is rotatably connected to the screening frame 1 to convert the circular motion of the rotating disk 13 into the forward and backward motion of the screening frame 1. A column 15 is fixedly connected to the left end of the rear side of the outer wall of the support frame 4 to support the storage bin 16. A storage bin 16 is fixedly connected to the front side of the top of the column 15 to store the buttons to be screened and make them fall evenly. A quick installation mechanism 2 is arranged on the outer wall of the screening frame 1. The quick installation mechanism 2 is used for quickly installing the corrugated plates 7;

[0034] Specifically, the screening box 1 is the core component for carrying and screening buttons. The rollers 3 fixedly connected to the periphery of its bottom are slidably connected to the chutes 5 opened on the front and rear sides of the top of the support frame 4, enabling the screening box 1 to swing smoothly back and forth on the support frame 4, providing a power basis for screening. The limiting grooves 6 opened on the upper and lower sides of the inner wall of the screening box 1 are used to install the corrugated plates 7, playing a role in positioning and fixing. The multiple screening holes 8 opened on the top of the corrugated plate 7 screen the buttons according to the aperture size. The corrugated plate 7 is designed in a corrugated shape, which can adjust the posture of the buttons and help them quickly align with the screening holes 8. The multiple blocking strips 9 provided on the left and right sides of the top are fixedly connected to the inner wall of the screening box 1 at the front and rear ends, which can smooth out the buttons, prevent large accumulations, and ensure the orderly progress of screening. The discharge plate 10 fixedly connected to the front side of the right end of the outer wall of the screening box 1 is responsible for exporting the screened buttons to different storage devices. The fixed seat 11 fixedly connected to the left side of the support frame 4 is used to install the motor 12. The output end of the motor 12 is connected to the rotating disk 13, and the rocker 14 is driven to make a circular motion through the rotating disk 13. The right end of the rocker 14 is rotatably connected to the screening box 1, thereby driving the screening box 1 to swing back and forth. The column 15 fixedly connected to the left end of the rear side of the outer wall of the support frame 4 supports the storage bin 16 at the front side of the top. The bottom opening of the storage bin 16 is small, which can make the buttons evenly fall onto the corrugated plate 7. The quick installation mechanism 2 provided on the outer wall of the screening box 1 can realize the quick installation and replacement of the corrugated plate 7 to meet different screening requirements. Each component cooperates with each other, effectively solving the problems that it is difficult for the buttons to quickly align with the screening holes 8 and the screening efficiency is low in the prior art.

[0035] Referring to Figure 1 、 Figure 2 and Figure 5 , the quick installation mechanism 2 includes multiple installation frames 201, which provide a support structure for installing and fixing other components. The rear sides of the multiple installation frames 201 are respectively fixedly connected to the left side of the front end of the outer wall of the screening box 1. The inner walls of the multiple installation frames 201 are all slidably connected with insertion rods 202, allowing the insertion rods 202 to move back and forth in the installation frames 201 to realize the installation and fixing operations of the corrugated plates 7. Limiting rings 203 are fixedly connected to the outer walls of the multiple insertion rods 202 to prevent the insertion rods 202 from disengaging from the installation frames 201, and play a key connection and conduction role during the action of the springs 204. Springs 204 are fixedly connected to the front sides of the outer walls of the multiple limiting rings 203, storing and releasing energy through elastic deformation, providing power for the automatic reset of the insertion rods 202. The front ends of the multiple springs 204 are respectively fixedly connected to the corresponding installation frames 201 to ensure that the springs 204 stably transmit force between the installation frames 201 and the limiting rings 203, ensuring that the insertion rods 202 can act according to the design requirements. Limiting holes 205 are opened on the left side of the front end of the outer walls of the multiple corrugated plates 7. The multiple insertion rods 202 are respectively engaged with the corresponding limiting holes 205 passing through the screening box 1. The limiting holes 205 cooperate with the insertion rods 202. When they are aligned, the insertion rods 202 are allowed to insert, thereby restricting the left and right movement of the corrugated plates 7;

[0036] Specifically, the rear sides of multiple mounting frames 201 are fixedly connected to the front left side of the outer wall of the screening frame 1, providing an installation basis for the entire quick-installation mechanism 2, enabling components such as the insertion rod 202 to be stably connected to the screening frame 1. The inner wall of the mounting frame 201 is slidably connected to the insertion rod 202, providing a moving track for the insertion rod 202, allowing the insertion rod 202 to move back and forth according to installation requirements. The limiting ring 203 fixed to the outer wall of the insertion rod 202 is connected to the spring 204. Its function is to drive the spring 204 to compress or stretch when the insertion rod 202 moves. The front end of the spring 204 is fixed to the mounting frame 201. When the insertion rod 202 is pulled, the spring 204 is squeezed by the limiting ring 203 to store elastic potential energy. After the insertion rod 202 is released, the spring 204 releases the elastic potential energy to push the insertion rod 202 back to its original position. The limiting hole 205 opened on the front left side of the outer wall of the corrugated plate 7 cooperates with the insertion rod 202. During the installation of the corrugated plate 7, the insertion rod 202 is pulled and then the corrugated plate 7 is installed. When the limiting hole 205 is aligned with the insertion rod 202, the spring 204 pushes the insertion rod 202 into the limiting hole 205 to achieve the engagement of the two, thereby quickly and firmly fixing the corrugated plate 7 on the screening frame 1, conveniently and quickly meeting the replacement requirements of corrugated plates 7 with different apertures.

[0037] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in, a mounting plate 17 is fixedly connected to the right side of the outer wall of the above-mentioned storage bin 16. A lighting lamp 18 is fixedly connected to the bottom of the mounting plate 17, which can illuminate the screening area and facilitate observing the button screening situation. A mounting box 19 is fixedly connected to the front side of the top of the mounting plate 17. An alarm 20 is fixedly connected to the inner wall of the mounting box 19, which emits an alarm when the device has an abnormality to remind the operator. Foot seats 21 are fixedly connected to the four peripheries of the bottom of the support frame 4. Positioning holes 22 are opened at the bottoms of the inner walls of the multiple foot seats 21, which facilitates the stable installation of the entire screening device on the working site through a fixing device.

[0038] Specifically, the lighting lamp 18 at the bottom of the mounting plate 17 on the right side of the outer wall of the storage bin 16 can illuminate the screening area and facilitate observing the button screening situation. The alarm 20 in the mounting box 19 on the front side of the top of the mounting plate 17 can emit an alarm when the device has an abnormality to remind the operator. The positioning holes 22 at the bottoms of the inner walls of the foot seats 21 on the four peripheries of the bottom of the support frame 4 facilitate the stable installation of the entire screening device on the working site through a fixing device.

[0039] Refer to Figure 1 、 Figure 2 and Figure 3, a drawer 23 is slidably connected to the front side of the inner wall of the fixed seat 11, which is convenient for storing tools. A handle 24 is fixedly connected to the front side of the outer wall of the drawer 23, which is convenient for easily pulling out or pushing in the handle 24; a controller 25 is fixedly connected to the front side of the top of the fixed seat 11, which is used to control the motor 12 to realize the control of the operation state of the screening device. A plurality of control buttons 26 are fixedly connected to the right side of the outer wall of the controller 25, which are used to control the motor 12; the front ends of a plurality of inserting rods 202 are all slidably connected with pull rings 27, and the surfaces of the plurality of pull rings 27 are anti-slip treated, which is convenient for the operator to pull the inserting rods 202 to quickly install or disassemble the corrugated plate 7;

[0040] Specifically, the drawer 23 on the front side of the inner wall of the fixed seat 11 can be easily pulled out or pushed in through the handle 24 on the front side of the outer wall, which is convenient for storing tools. The controller 25 on the front side of the top and the control buttons 26 on the right side of the outer wall are used to control the motor 12 to realize the control of the operation state of the screening device. The pull ring 27 slidably connected to the front end of the inserting rod 202 has an anti-slip surface, which is convenient for the operator to pull the inserting rod 202 to quickly install or disassemble the corrugated plate 7.

[0041] Working principle: When the device is started, the motor 12 is first turned on. The rotation of the motor 12 drives the rotating disk 13 fixedly connected to its output end to start rotating. The rocker 14 rotatably connected to the top of the front side of the outer wall of the rotating disk 13 will perform a circular motion as the rotating disk 13 rotates, and then drive the screening frame 1 connected to it to move back and forth. During this process, the rollers 3 fixedly connected to the four sides of the bottom of the screening frame 1 are slidably connected to the chutes 5 opened on the front and rear sides of the top of the support frame 4. This structural design makes the screening frame 1 swing more smoothly when swinging back and forth, reduces the frictional resistance during the movement process, and ensures the stable and efficient swinging of the screening frame 1. Subsequently, the buttons to be screened are poured into the storage bin 16 located at the front side of the top of the column 15. The opening at the bottom of the storage bin 16 is relatively small. This design enables the buttons to fall more evenly from the bottom of the storage bin 16 onto the corrugated plate 7 at the top. The plurality of corrugated plates 7 adopt a corrugated structure. This special shape can effectively adjust the posture of the buttons. Under the continuous swinging of the screening frame 1, the buttons are more likely to quickly align with the sieve holes 8, greatly improving the screening efficiency and solving the problem that it is difficult for the buttons to quickly align with the sieve holes 8 in the prior art. At the same time, a plurality of blocking strips 9 are arranged on the left and right sides of the top of the corrugated plate 7, and the front and rear ends of which are fixedly connected to the inner wall of the screening frame 1. These blocking strips 9 can flatten the buttons and prevent the buttons from accumulating in large quantities, further ensuring the smooth progress of the screening process. The sizes of the sieve holes 8 on the plurality of corrugated plates 7 gradually decrease from top to bottom, enabling the device to separate buttons of different sizes. As the screening frame 1 continues to swing, the screened buttons move to the right side of the corrugated plate 7 and finally fall out of the discharge plate 10 and into different storage devices, completing the entire button screening process. The entire device realizes the screening of buttons efficiently through the coordinated operation of each component, significantly improving the screening efficiency;

[0042] And during the use of the button sieving device, when it is necessary to replace the corrugated plate 7 with different aperture diameters to meet different sieving requirements, the operator operates the insertion rod 202 and pulls it outwards. Since the insertion rod 202 is fixedly connected to the limit ring 203, the movement of the insertion rod 202 will drive the limit ring 203 to move together. At this time, the spring 204 fixedly connected to the front side of the outer wall of the limit ring 203 will be compressed, and the spring 204 will undergo elastic deformation due to the external force and store elastic potential energy. Subsequently, the operator aligns the right end of the corrugated plate 7 to be installed with the corresponding limit groove 6 and inserts it. Then, the corrugated plate 7 is moved to the right along the direction of the limit groove 6. When the corrugated plate 7 moves to a certain position, the pulled insertion rod 202 is released. At this time, since the spring 204 stored elastic potential energy before, after the pressure is released, the spring 204 begins to recover its deformation and generates a force pushing the insertion rod 202 backward. Under the action of this force, after the rear end of the insertion rod 202 fits against the outer wall of the corrugated plate 7, the corrugated plate 7 is continuously slid to the right side of the limit groove 6. When it slides to the position where the limit hole 205 opened on the left side of the front end of the outer wall of the corrugated plate 7 is aligned with the insertion rod 202, the rear end of the insertion rod 202 will quickly insert into the corresponding limit hole 205 under the continuous action of the spring 204. Once the insertion rod 202 is inserted into the limit hole 205, the left and right movement of the corrugated plate 7 is restricted, thereby firmly fixing the corrugated plate 7 in the sieve frame 1 and completing the rapid installation of the corrugated plate 7.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
