[0025] Vibrating disc 10, vibrating disc 10 is used for containing screw,

[0026] Spiral channel 20, spiral channel 20 surrounds the outer wall at vibrating disc 10, and the top of spiral channel 20 is open, and spiral channel 20 is sequentially provided with first discharge gate 21 and second discharge gate 22 along spiral descending direction, and first discharge gate 21 is located the side of spiral channel 20,

[0027] Spiral conveying board 30, one end of spiral conveying board 30 is connected with the top edge alignment of vibrating disc 10, and spiral conveying board 30 is located the top of spiral channel 20, and the length of spiral conveying board 30 is less than the length of spiral channel 20, and spiral conveying board 30 is provided with first opening 31, and first opening 31 is communicated with first discharge gate 21,

[0028] Arc baffle 40, arc baffle 40 is connected with spiral channel 20 through connecting piece, and arc baffle 40 is located the top of spiral conveying board 30, and the preset gap is formed between arc baffle 40 and spiral conveying board 30,

[0029] Spiral inclined wall 50, spiral inclined wall 50 is arranged in the inner wall of vibrating disc 10, and one end of the bottom of spiral inclined wall 50 is connected to the inner bottom of vibrating disc 10, and one end of the top of spiral inclined wall 50 is aligned with the top edge alignment of vibrating disc 10 and one end of spiral conveying board 30.

[0030] It should be noted that the vibration disc 10 is vibrated by the motor, so that the screws to be screened inside the vibration disc 10 rise along the spiral inclined wall 50 to the top of the vibration disc 10. How to realize the vibration of the vibration disc 10 by the motor is the prior art, and the present application does not make any improvement, and will not be described in detail here.

[0031] It should be noted that the other end of the spiral conveying plate 30 is higher than the end of the spiral conveying plate 30 aligned with the top edge of the vibration disc 10. The screws to be screened rise to the top of the vibration disc 10 along the spiral inclined wall 50, and after abutting against the upper surface of the spiral conveying plate 30 aligned with the top of the vibration disc 10, they rise along the spiral conveying plate 30.

[0032] It should be noted that the first opening 31 provided on the spiral conveying plate 30 has a fixed width, or a gap is provided on the spiral conveying plate 30, and a limiting plate is connected to the gap by a connecting piece, and the limiting plate and the gap form the first opening 31, so that the width of the first opening 31 can be adjusted, so as to adjust the width of the first opening 31 according to the production of the required screws.

[0033] It should be noted that the first discharge port 21 discharges the screws meeting the diameter and length requirements, so as to facilitate the collection of the screws meeting the production requirements and the application in the subsequent toy assembly process. The second discharge port 22 collects the screws not meeting the diameter requirements, so as to facilitate the subsequent secondary screening.

[0034] It should be noted that the connecting piece is a screw. The screw is loosened to remove the arc-shaped baffle 40 from the spiral channel 20. The arc-shaped baffle 40 is moved to make the distance between the arc-shaped baffle 40 and the preset gap of the spiral conveying plate 30 the diameter of the required screw. Then the arc-shaped baffle 40 is connected to the spiral channel 20 by the screw. Before starting the screw screening device, the distance of the preset gap is adjusted in advance by the connecting piece.

[0035] It should be noted that the screws to be screened include screw heads and screw rods, and the distance of the preset gap is the diameter of the screw rod of the required screw, and the diameter of the screw head is greater than the distance of the preset gap. If the diameters of the screw rod and the screw head of the screws to be screened are both smaller than the distance of the preset gap, the screws to be screened will fall from the arc-shaped baffle 40 to the top open spiral channel 20.

[0036] It should be noted that at the top end of the vibration disc 10, the spiral conveying plate 30 and the spiral inclined wall 50 are located in the same plane, and the arc-shaped baffle 40 is located above the spiral conveying plate 30 and the spiral inclined wall 50, so that the screws rising along the spiral inclined wall 50 can smoothly enter the preset gap between the arc-shaped baffle 40 and the spiral inclined wall 50, thereby realizing the diameter screening of the screws to be screened.

[0037] It should be noted that the screw to be screened is lifted along the spiral inclined wall 50 until it moves to the top of the vibrating disc 10 and is located between the spiral conveying plate 30 and the arc-shaped baffle 40, so that the screw with the required diameter has the screw head facing the inside of the vibrating disc 10 and the screw rod facing the outside of the vibrating disc 10, and the arc-shaped baffle 40 blocks the movement of the screw head to the outside of the vibrating disc 10 to prevent the screw from falling.

[0038] It should be noted that the screw with the required diameter is lifted along the spiral conveying plate 30 to the first opening 31, the width of the first opening 31 is the length of the required screw, if the length of the screw to be screened meets the requirements, it will fall through the first opening 31 to the spiral channel 20 and be discharged from the first discharge port 21; if it does not meet the requirements, it cannot fall to the spiral channel 20 and continues to rise along the spiral conveying plate 30.

[0039] It should be noted that the distance of the preset gap is adjusted by the connecting piece in advance, and the distance of the preset gap is set as the diameter of the required screw; the screw to be screened is placed in the vibrating disc 10, the vibrating disc 10 is started, the screw to be screened enters the spiral inclined wall 50 and is lifted along the spiral inclined wall 50 to the top of the vibrating disc 10; when the screw to be screened is located between the arc-shaped baffle 40 and the spiral conveying plate 30, if the diameter of the screw head of the screw to be screened is smaller than the distance of the preset gap, the screw to be screened falls through the arc-shaped baffle 40 to the spiral channel and moves to the second discharge port 22; if the diameter of the screw rod of the screw to be screened is smaller than or equal to the distance of the preset gap and the diameter of the screw rod head of the screw to be screened is greater than the distance of the preset gap, the screw to be screened is lifted along the spiral conveying plate 30 to the first opening 31; if the length of the screw to be screened with the required diameter is greater than the width of the first opening 31, it continues to rise along the spiral conveying plate 30; if the length of the screw to be screened with the required diameter is smaller than or equal to the width of the first opening 31, the screw to be screened with the required diameter falls through the first opening 31 to the spiral channel 20 and is discharged from the first discharge port 21 of the spiral channel 20. Through the screw screening device of the embodiment, the screw is subjected to diameter screening and length screening, so that the required size specification screw is obtained, and the production efficiency of the toy manufacturer is improved.

[0040] In addition, in an embodiment, referring to Figure 1 , the side of the spiral conveying plate extends out of the third discharge port 33, the spiral conveying plate is provided with the second opening 32, the second opening 32 is located between the first opening 31 and the third discharge port 33, the width of the second opening 32 is greater than the width of the first opening 31, the side of the spiral channel 20 is also provided with the fourth discharge port, and the second opening 32 is communicated with the fourth discharge port.

[0041] It should be noted that the second opening 32 is provided, the width of the second opening 32 is greater than the width of the first opening 31, and the screws meeting the diameter requirement but not meeting the width requirement of the first opening 31 are subjected to secondary screening. If the length of the screw to be screened is less than or equal to the width of the second opening 32, the screw falls through the second opening 32 to the fourth discharge port and is discharged from the fourth discharge port; if the length of the screw to be screened is greater than the width of the second opening 32, the screw moves along the spiral conveying plate 30 to the third discharge port 33 and is discharged from the third discharge port 33, and the screw discharged from the third discharge port 33 is the screw meeting the diameter requirement but not meeting the length requirement.

[0042] In addition, in an embodiment, referring to Figure 1 , the bottom end of the spiral channel 20 is provided with a baffle.

[0043] It should be noted that, in the process of rising along the spiral conveying plate 30, if the vibration frequency of the vibration disc 10 is too large, part of the screws meeting the diameter requirement will fall into the spiral channel 20 without length screening through the first opening 31, that is, the screw to be screened falls between the arc-shaped baffle 40 and the first opening 31 and falls into the spiral channel 20. In order to re-screen the screws falling into the spiral channel 20, the accidentally falling screws are discharged and collected through the second discharge port 22, so as to facilitate re-screening. In order to avoid the accidentally falling screws interfering with the screws screened by the diameter and length and discharged through the first discharge port 21, the bottom of the first discharge port 21 is provided with a bottom plate, and the height of the bottom plate is higher than the height of the bottom of the spiral channel 20.

[0044] In addition, in an embodiment, referring to Figure 1 , the sidewall of the vibration disc 10 is provided with a third opening, and the third opening is communicated with the second discharge port 22.

[0045] It should be noted that, by opening the third opening, the screws accidentally falling into the spiral channel 20 flow back to the inside of the vibration disc 10 through the third opening, so that the screws discharged from the second discharge port 22 do not need to be collected and placed in the vibration disc 10 again.

[0046] In addition, in an embodiment, referring to Figure 1 , the sidewall of the vibration disc 10 is provided with a fourth opening, the lower edge of the fourth opening is aligned with the spiral inclined wall 50, the outer wall of the vibration disc 10 is provided with a collection port 60, and the fourth opening is aligned with the collection port 60.

[0047] It should be noted that, due to the complex environment of the toy manufacturing workshop, the screws of various sizes are mixed with some impurities such as paper sheets and wood chips. The impurities are small in mass and are lifted along the spiral inclined wall 50 under the action of the vibration disc 10. When the impurities pass through the fourth opening, the impurities are vibrated out through the fourth opening under the action of the vibration disc 10 and are moved to the collection port 60. The collection port 60 collects the impurities, thereby preventing the impurities from flowing back to the vibration disc 10 and interfering with the screw screening process.

[0048] In addition, in an embodiment, referring to Figure 1 , the side of the spiral conveying plate 30 extends out the fifth discharge port 23, and the preset gap is directed towards the fifth discharge port 23.

[0049] It should be noted that the screws that do not fall through the first opening 31 to the spiral channel 20 are lifted along the spiral conveying plate 30 to the fifth discharge port 23 and are discharged from the fifth discharge port 23. The screws discharged from the fifth discharge port 23 are screws that meet the diameter requirement but do not meet the length requirement.

[0050] It should be noted that if the head diameter of the screw to be screened is smaller than the preset gap, the screw to be screened falls through the arc-shaped baffle 40 to the third discharge port 23 and is discharged from the third discharge port 23. The third discharge port 23 is provided to concentrate the screws that do not meet the diameter requirement and to avoid interfering with the screening process of the screw to be screened.

[0051] In addition, in an embodiment, referring to Figure 1 , the inner bottom center of the vibration disc 10 is protruded.

[0052] It should be noted that the inner bottom center of the vibration disc 10 is protruded to enable the screws located inside the vibration disc 10 to quickly enter the bottom end of the spiral inclined wall 50, thereby being lifted along the spiral inclined wall 50 to the top end of the vibration disc 10, thereby improving the screening efficiency of the screw screening device.

[0053] It should be noted that the distance of the preset gap is adjusted in advance by the connecting piece, and the distance of the preset gap is set as the diameter of the required screw; the screw to be screened is placed on the vibration disc 10, the vibration disc 10 is started, the screw to be screened enters the spiral inclined wall 50, and rises along the spiral inclined wall 50 to the top of the vibration disc 10, when the screw to be screened is located between the arc-shaped baffle 40 and the spiral conveying plate 30, if the diameter of the screw head of the screw to be screened is smaller than the distance of the preset gap, the screw to be screened is discharged from the first discharge port 21 through the arc-shaped baffle 40; if the diameter of the screw rod of the screw to be screened is smaller than or equal to the distance of the preset gap, and the diameter of the screw rod head of the screw to be screened is greater than the distance of the preset gap, the screw to be screened rises along the spiral conveying plate 30 until the first opening 31; if the length of the screw to be screened is smaller than or equal to the width of the first opening 31, the screw to be screened falls through the first opening 31 to the spiral channel 20, and then is discharged from the first discharge port 21 of the spiral channel 20; if the length of the screw to be screened is greater than the width of the first opening 31, the screw to be screened continues to rise along the spiral conveying plate 30 to the second opening 32, if the length of the screw to be screened is smaller than or equal to the width of the second opening 32, the screw to be screened falls through the second opening 32 to the fourth discharge port, and is discharged from the fourth discharge port; if the length of the screw to be screened is greater than the width of the second opening 32, the screw to be screened rises along the spiral conveying plate 30 to the third discharge port 33, and is discharged from the third discharge port 33; if the screw to be screened falls between the arc-shaped baffle 40 and the first opening 31 to the spiral channel 20, the screw to be screened moves along the spiral channel 20 to the second discharge port 22, and flows back to the inside of the vibration disc 10 through the third opening.
