Technical Field

[0001] The invention relates to the technical field of bolt screening, and in particular to an automatic screening device and method for oil-sealing bolts. Background Art

[0002] Bolts, as important mechanical parts, are widely used in the machinery industry. During the production and processing of bolts, it is usually necessary to screen the bolts so that bolts of different specifications can be classified and used. The existing bolt screening is mostly done manually, and the screening efficiency is slow, resulting in low production efficiency. At the same time, due to errors in manual screening, the quality requirements of the bolts cannot be guaranteed, thereby reducing the product qualification rate.

[0003] The prior art CN216620877U discloses a detection device for bolt screening. By setting a screening plate and a detection hole, bolts with the same specifications can be detected through the detection holes formed by the screening plate, thereby achieving the effect of detecting and screening out bolts with the same specifications; by setting an electric push rod and a push plate, the push plate can be driven by the electric push rod to slide inside the screening plate and the detection hole, and the bolts that do not meet the detection holes are pushed out, thereby achieving the effect of removing bolts that do not meet the detection standards. The detection device for bolt screening has a simple structural design, low customization cost, and simple operation process. It can effectively and quickly detect and screen out bolts that meet the specifications, which not only greatly improves production efficiency, but also increases the qualified rate of bolts leaving the factory, thereby ensuring the quality of bolts.

[0004] However, the above-mentioned bolt screening device can only screen bolts within the same range, resulting in only single-stage screening of the bolts and not multi-stage screening of the bolts, thereby reducing the scope of application of the bolt screening device. Summary of the invention

[0011] Wherein, a limit plate is arranged outside the output shaft of the driving motor and outside the transmission rod, and the limit plate is used to limit the position of the connecting belt to prevent the connecting belt from falling off the output shaft of the driving motor or the transmission rod.

[0012] The present invention also provides an automatic screening method for oil sealing bolts, comprising the following steps:

DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0025] First embodiment:

[0026] See also Figures 1 to 3 ,in, Figure 1 is a schematic diagram of the overall structure of the automatic screening device for oil sealing bolts according to the first embodiment of the present invention, Figure 2 is a schematic diagram of the connection between the connecting block 107 and the fixing block 108 according to the first embodiment of the present invention. Figure 3 It is a cross-sectional schematic diagram along the screening box 102 of the first embodiment of the present invention. The present invention provides an automatic screening device for oil sealing bolts, including a frame 101, a connecting mechanism, a screening box 102, a shaking mechanism, a first collecting box 103 and a second collecting box 104. The connecting mechanism includes a fixed plate 105, a supporting block 106, a connecting block 107 and a fixed block 108. The shaking mechanism includes a supporting plate 109, a driving member, a rotating shaft 110 and a connecting plate 111. The driving member includes a driving motor 112 and a transmission rod 113.

[0027] In this embodiment, the oil sealing bolts are poured into the feed port 114 so that they move downward under the action of gravity and are screened in turn at the first screening hole 116 and the second screening hole 117, so that the oil sealing bolts that meet the specifications after screening will fall into the right chamber and the left chamber of the first collecting box 103 in turn, while the oil sealing bolts that do not meet the specifications after screening will continue to move downward under the action of gravity and finally fall into the second collecting box 104 from the discharge port 115, thereby realizing multi-stage screening of the oil sealing bolts. The screening box 102 is intermittently squeezed by the shaking mechanism, so that the screening box 102 can be shaken back and forth in the frame 101, thereby accelerating the screening rate of the oil sealing bolts in the screening box 102, and the multi-stage screening of the oil sealing bolts is improved, thereby improving the scope of application of the bolt screening device.

[0028] The screening box 102 is connected to the frame 101 through the connecting mechanism, the screening box 102 is tilted downward, the screening box 102 has a feed port 114 and a discharge port 115, the feed port 114 and the discharge port 115 are respectively arranged on the upper and lower sides of the screening box 102, the bottom of the screening box 102 is evenly distributed with a first screening hole 116 and a second screening hole 117, the size of the first screening hole 116 is smaller than the size of the second screening hole 117, and the first screening hole 116 is close to the feed port 114, the shaking mechanism is located on the side of the frame 101 close to the screening box 102, and the first collecting box 10 3 is arranged below the first screening hole 116 and the second screening hole 117, the second collecting box 104 is arranged below the discharge port 115, the interior of the screening box 102 is a hollow structure, and since the screening box 102 is arranged to be tilted downward, the oil sealing bolts entering the screening box 102 from the feed port 114 will gradually move downward under the action of gravity and finally be discharged from the discharge port 115. Since the size of the first screening hole 116 is smaller than that of the second screening hole 117, the first screening hole 116 and the second screening hole 117 can screen the oil sealing bolts of different specifications and sizes in turn, thereby realizing multi-stage screening of the oil sealing bolts.

[0029] Secondly, a partition plate 118 is provided in the first collection box 103 , and the partition plate 118 divides the first collection box 103 into two left and right chambers, so as to achieve the classification and collection of the oil sealing bolts screened out by the first screening hole 116 and the second screening hole 117 .

[0030] Again, the fixing plate 105 is arranged in the frame 101, the supporting block 106 is arranged below the fixing plate 105, the connecting block 107 is movably connected with the supporting block 106 and is located below the supporting block 106, the fixing block 108 is movably connected with the connecting block 107 and is arranged outside the screening box 102, and the movable connection between the connecting block 107 and the supporting block 106 or the fixing block 108 is realized by connecting the pin 119, the supporting block 106 and the fixing block 108 both have grooves, and the connecting block 107 can be respectively The support block 106 and the fixing block 108 rotate in the grooves. When the screening box 102 swings back and forth in the frame 101, the fixing block 108 will follow the screening box 102 to swing back and forth in the frame 101, thereby driving the connecting block 107 to swing back and forth in the frame 101, and then the connection between the frame 101 and the screening box 102 can be achieved through the fixing plate 105, the support block 106, the connecting block 107 and the fixing block 108, and the swinging back and forth of the screening box 102 in the frame 101 will not be affected.

[0031] At the same time, the support plate 109 is arranged in the frame 101, and the driving member is used to drive the rotating shaft 110 to rotate. The rotating shaft 110 is located on the side of the driving member close to the screening box 102, and the connecting plate 111 is rotatably connected to the rotating shaft 110 and is arranged on the support plate 109. The rotating shaft 110 has a protrusion 122 outside, and the number of the protrusions 122 is two, and they are respectively arranged at relative positions outside the rotating shaft 110. When the rotating shaft 110 rotates along its own axis, the protrusion 122 will also rotate along the axis of the rotating shaft 110, so that the protrusion 122 will intermittently squeeze the screening box 102 during the rotation process, thereby driving the screening box 102 to swing back and forth in the frame 101.

[0032] In addition, the driving motor 112 is arranged on the supporting plate 109, the transmission rod 113 is connected to the output shaft of the driving motor 112 via a connecting belt 120, and the transmission rod 113 is arranged on the side of the rotating shaft 110 away from the connecting plate 111. Since the output shaft of the driving motor 112 is connected to the transmission rod 113 via the connecting belt 120, when the driving motor 112 is started, the output shaft of the driving motor 112 will rotate along its own axis, so that the transmission rod 113 can be driven to rotate along its own axis through the connecting belt 120, and then the rotating shaft 110 can be driven to rotate along its own axis.

[0033] Finally, a limit plate 121 is provided outside the output shaft of the driving motor 112 and outside the transmission rod 113. The limit plate 121 is used to limit the position of the connecting belt 120 to prevent the connecting belt 120 from falling off the output shaft of the driving motor 112 or the transmission rod 113.

[0034] When using an automatic screening device for oil sealing bolts of the present embodiment, when automatic screening of the oil sealing bolts is required, the driving motor 112 is started, so that the power output by the output shaft of the driving motor 112 drives the axis of the transmission rod 113 to rotate through the connecting belt 120, thereby driving the rotating shaft 110 to rotate along its own axis, and then driving the protrusion 122 to intermittently squeeze the screening box 102. The intermittent squeezing of the screening box 102 by the protrusion 122 makes the screening box 102 swing back and forth in the frame 101, thereby accelerating the falling rate of the oil sealing bolts in the screening box 102, and at the same time, preventing the oil sealing bolts from being stuck in the first screening hole 116 or the second screening hole 117.

[0035] When the screening box 102 is shaken back and forth, the first collecting box 103 is first placed directly below the first screening hole 116 and the second screening hole 117, and then the second collecting box 104 is placed directly below the discharge port 115. Thereafter, the oil sealing bolts are poured into the feed port 114, so that the oil sealing bolts will gradually move downward from the feed port 114 into the screening box 102 under the combined action of gravity and shaking force. When the oil sealing bolts reach the first screening hole 116 during the downward movement, the first screening hole 116 will perform the first screening on the oil sealing bolts, so that the oil sealing bolts smaller than the first screening hole 116 will fall into the right chamber of the first collecting box 103, while the oil sealing bolts larger than the first screening hole 116 will continue to move downward.

[0036] When the oil sealing bolt reaches the second screening hole 117 during the downward movement, the second screening hole 117 will screen the oil sealing bolt for the second time, so that the oil sealing bolts smaller than the second screening hole 117 will fall into the left chamber of the first collecting box 103, while the oil sealing bolts larger than the second screening hole 117 will continue to move downward.

[0037] When the oil sealing bolt reaches the edge of the discharge port 115 during the downward movement, the oil sealing bolt will fall from the discharge port 115 into the second collecting box 104, so that the first collecting box 103 and the second collecting box 104 can respectively classify and collect the oil sealing bolts of different sizes, thereby completing the entire process of automatic screening of the oil sealing bolts.

Thereafter, pour the oil sealing bolt into the feed port 114, so that the oil sealing bolt will gradually move downward from the feed port 114 into the screening box 102 under the combined action of gravity and shaking force. When the oil sealing bolt reaches the first screening hole 116 during the downward movement, the first screening hole 116 will perform the first screening on the oil sealing bolt.

[0042] S102, after screening, the oil sealing bolts smaller than the first screening hole 116 will fall into the right chamber of the first collecting box 103, while the other oil sealing bolts continue to move downward.

[0043] Specifically, after the first screening of the oil sealing bolts, the oil sealing bolts smaller than the first screening holes 116 will fall into the right chamber of the first collecting box 103, while the oil sealing bolts larger than the first screening holes 116 will continue to move downward.

[0044] S103, when the oil sealing bolts reach the second screening hole 117, the oil sealing bolts smaller than the second screening hole 117 will fall into the left chamber of the first collecting box 103, while the other oil sealing bolts continue to move downward.

[0045] Specifically, when the oil sealing bolt reaches the second screening hole 117 during the downward movement, the second screening hole 117 will screen the oil sealing bolt for the second time, so that the oil sealing bolts smaller than the size of the second screening hole 117 will fall into the left chamber of the first collecting box 103, while the other oil sealing bolts continue to move downward.

[0046] S104, when the oil sealing bolts reach the edge of the discharge port 115, the oil sealing bolts will fall from the discharge port 115 into the second collection box 104, completing the entire process of automatic screening of the oil sealing bolts.
