DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-9 As shown, the present invention is an oil seal packaging equipment, including a vibration plate 1 for conveying oil seals and a conveying mechanism 3 for conveying packaging paper 2, a tray 4 is arranged above the conveying mechanism 3, the discharge end of the vibration plate 1 is connected with a feeding mechanism 5, and a packaging mechanism 6 corresponding to the feeding end of the feeding mechanism 5 is installed on the tray 4; the packaging mechanism 6 includes an inner gear ring 61, a receiving mechanism 62, a driving mechanism 63 and a pressing mechanism 64, the inner gear ring 61 is rotatably connected to the top of the tray 4 through the driving mechanism 63, and the driving mechanism 63 is used to drive the inner gear ring 61 to rotate, a plurality of receiving mechanisms 62 are evenly distributed on the top of the inner gear ring 61 in a ring shape, and the receiving mechanism 62 is used to orderly arrange the oil seals discharged from the feeding end of the feeding mechanism 5, the pressing mechanism 64 is installed on the top of the tray 4, and the pressing mechanism 64 is used to press the oil seals arranged in an orderly manner in the receiving mechanism 62 into the packaging paper 2.

[0039] It should be noted that, when in use, the oil seal is transported to the unloading mechanism 5 in an orderly manner by the vibration plate 1, and the inner gear ring 61 is controlled by the driving mechanism 63 to rotate the same angle each time, so that after each rotation, there is a receiving mechanism 62 corresponding to the unloading end of the unloading mechanism 5, so as to facilitate the orderly loading of the oil seal. When the receiving mechanism 62 loaded with the oil seal rotates to the corresponding position of the pressing mechanism 64, at the same time, the conveying mechanism 3 is used to drive the packaging paper 2 to move to the corresponding position of the pressing mechanism 64, and the pressing mechanism 64 is used to press the receiving mechanism 62;

[0040] During the downward pressing process of the material receiving mechanism 62, the packaging paper 2 is pressed to make it concave, so that after the material receiving mechanism 62 rises and resets, the oil seal loaded in the material receiving mechanism 62 falls into the concave packaging paper 2 in an orderly manner in a cylindrical shape, thereby realizing the orderly arrangement and packaging of the oil seal.

[0041] like Figure 1 and Figure 3 As shown, the conveying mechanism 3 includes a conveyor belt 31 and a baling tube 32 with a suction cup (not shown in the figure), a plurality of baling tubes 32 are evenly installed on the conveyor belt 31, the suction cup is installed on the edge of the baling tube 32 away from one end of the conveyor belt 31, and the suction cup is used to adsorb the wrapping paper 2 to the end of the baling tube 32.

[0042] It should be noted that in this embodiment, the wrapping paper 2 is an environmentally friendly paper with a circular structure, and the wrapping paper 2 is adsorbed and positioned by a suction cup. This is a prior art and will not be described in detail here. The wrapping paper 2 after adsorption and positioning can move synchronously with the packing tube 32 on the conveyor belt 31. When the wrapping paper 2 moves to the bottom of the tray 4, the wrapping paper 2 is close to the bottom of the tray 4, and the material receiving mechanism 62 ( Figure 2 (As shown in the figure) During the pressing process, the wrapping paper 2 can be pressed into the packing tube 32, and the wrapping paper 2 in the packing tube 32 is concave, so as to facilitate the loading and packing of the oil seal.

[0043] like Figure 1 and Figure 5 As shown, the material discharge mechanism 5 includes a material guide trough 51, a baffle 52 and a material discharge hole 53. The material guide trough 51 is connected to the discharge end of the vibration disk 1. The end of the material guide trough 51 away from the vibration disk 1 is an arc-shaped structure. The material discharge hole 53 passes through the bottom of the trough at the end of the material guide trough 51 away from the vibration disk 1.

[0044] It should be noted that, in the present embodiment, the specification of the oil seal is adapted to the cross-sectional dimensions of the material guide groove 51, the oil seal can slide in an orderly manner along the material guide groove 51, the aperture of the discharge hole 53 is adapted to the size of the oil seal, and the oil seal can slide along the material guide groove 51 to its end and then fall through the discharge hole 53, the distance between the bottom of the baffle 52 and the bottom of the material guide groove 51 is adapted, and the baffle 52 is used to facilitate the position limiting of the oil seal to prevent the oil seal from deflecting when it slides to the position of the discharge hole 53 (when part of the oil seal is located above the discharge hole 53, the oil seal is easily deflected to a vertical state due to gravity).

[0045] like Figure 2 , Figure 5 and Figure 7 As shown, the material receiving mechanism 62 includes a receiving tube 621 with openings at both ends, a first spring 622, an arc plate 623 and a first retaining ring 624. A plurality of receiving tubes 621 are evenly distributed on the inner gear ring 61 in a ring shape, and the receiving tubes 621 are slidably arranged to penetrate the inner gear ring 61. The discharge hole 53 corresponds to the top opening of one of the receiving tubes 621. The first retaining ring 624 is fixedly mounted on the side wall of the receiving tube 621 near the top. The first spring 622 is installed between the first retaining ring 624 and the inner gear ring 61. The arc plate 623 is fixedly connected to the side wall of the first retaining ring 624 near the top.

[0046] It should be noted that the inner diameter of the receiving tube 621 is adapted to the aperture of the discharge hole 53. When the rotating inner gear ring 61 drives the receiving tube 621 to be located directly below the discharge hole 53, the oil seal sliding along the guide groove 51 can be orderly dropped into the receiving tube 621 through the discharge hole 53. An arc plate 623 is installed on each first baffle ring 624. Multiple arc plates 623 cooperate with multiple first baffle rings 624 to form a circular structure. The arc plate 623 is concentrically arranged with the inner gear ring 61. The arc plate 623 can be used to block the discharge hole 53 to ensure that after the receiving tube 621 located below the discharge hole 53 is separated from its operation, the discharge hole 53 will not discharge the oil seal. Only until the subsequent receiving tube 621 corresponds to the discharge hole 53, the oil seal will continue to be discharged.

[0047] like Figure 2 and Figure 4 As shown, the pressing mechanism 64 includes a first cylinder 641, a support frame 642 and a pressing hole 643. The pressing hole 643 is arranged through the tray 4. The pressing hole 643 is located above the conveyor belt 31, and the pressing hole 643 corresponds to one of the receiving cylinders 621. The support frame 642 is installed on the top of the tray 4, the first cylinder 641 is installed on the top of the support frame 642, and the piston rod of the first cylinder 641 is connected to a first pressure plate for pressing the receiving cylinder 621.

[0048] It should be noted that when the conveyor belt 31 drives the packaging paper 2 ( Figure 3 As shown) runs to the bottom of the pressing hole 643, and at the same time, the receiving cylinder 621 ( Figure 7 As shown in the figure, the receiving cylinder 621 moves to the top of the pressing hole 643. At this time, the oil seals loaded in order in the receiving cylinder 621 can pass through the pressing hole 643 and fall on the packaging paper 2 close to the bottom of the tray 4. Since the packaging paper 2 will support the oil seals, the oil seals in the receiving cylinder 621 will not be completely discharged. After the first cylinder 641 applies pressure to the receiving cylinder 621, it can pass through the pressing hole 643 to press the packaging paper 2 into the baling cylinder 32.

[0049] Then, after the first cylinder 641 drives the first pressure plate to rise and reset, the first spring 622 ( Figure 7 As shown in the figure, the baling tube 32 will be driven to rise and reset, so that all the oil seals in the baling tube 32 will be guided into and pressed into the baling tube 32 with the packaging paper 2. At this time, the multiple oil seals are orderly distributed in a cylindrical shape as a whole, and the outer side of the oil seals is wrapped with the packaging paper 2, thereby realizing the orderly packaging of the oil seals.

[0050] like Figure 2 and Figure 6As shown, the driving mechanism 63 includes a convex ring 631, a limiting slider 632, a gear 633 and a motor 634. The motor 634 is installed at the bottom of the tray 4. The output shaft of the motor 634 passes through the tray 4 and is coaxially connected to the gear 633. The gear 633 is meshed with the inner gear ring 61. The convex ring 631 is connected to the bottom of the inner gear ring 61. A rotating groove for the convex ring 631 to rotate is provided on the tray 4. A plurality of limiting sliders 632 are installed on the inner ring side wall of the convex ring 631. An annular groove for the limiting slider 632 to slide is provided on the groove wall of the rotating groove.

[0051] It should be noted that in this embodiment, the motor 634 is a stepper motor (a stepper motor can rotate a fixed step angle each time), and the gear 633 is used to facilitate the inner gear ring 61 to rotate a fixed angle each time, ensuring that after each rotation of the inner gear ring 61, there is a receiving tube 621 ( Figure 7 shown) is always located at the feed hole 53 ( Figure 5 As shown in the figure, the convex ring 631 cooperates with the rotation groove to improve the rotation stability of the inner gear ring 61, and the limiting slider 632 and the annular groove are used to facilitate the limiting, so that the convex ring 631 can only rotate along the rotation groove and will not disengage, thereby improving the position stability.

[0052] like Figure 2 and Figure 8 As shown, the support frame 642 includes a T-shaped plate, on which a second cylinder 7 is also installed, and the piston rod of the second cylinder 7 is connected to a second pressure plate. A bag pressing mechanism 8 that can be pressed by the second pressure plate is installed on the tray 4. The bag pressing mechanism 8 includes a pressure cylinder 81, a second spring 82, a second retaining ring 83, a strip groove 84 and a bag pressing member 85. The pressure cylinder 81 is slidably arranged through the tray 4, and the second retaining ring 83 is fixedly mounted on the side wall of the pressure cylinder 81 near the top. The second spring 82 is installed between the second retaining ring 83 and the tray 4. A plurality of strip grooves 84 are circumferentially distributed on the inner cylinder wall of the pressure cylinder 81, and the bag pressing member 85 is movably installed in the strip groove 84.

[0053] It should be noted that, in this embodiment, the pressing cylinder 81 can be sleeved on the packing cylinder 32 ( Figure 3 As shown in the figure, when the baling tube 32 loaded with the oil seal runs to just below the pressing tube 81, part of the wrapping paper 2 wrapped with the oil seal is still located on the outside of the baling tube 32. At this time, after the pressing tube 81 is pressed down, the wrapping paper 2 on the outside of the baling tube 32 will be sleeved on the outer tube wall of the baling tube 32. At the same time, the pressing bag member 85 in the pressing tube 81 will adaptively deflect. When the second spring 82 pushes the pressing tube 81 to reset, the pressing bag member 85 will push the wrapping paper sleeved on the outer tube wall of the baling tube 32 to rise. When the pressing bag member 85 is not in contact with the baling tube 32, it will deflect and reset. Since the pressing bag member 85 is deflected toward the center of the baling tube 32, the wrapping paper 2 on the outside of the baling tube 32 can be closed toward the center of the pressing tube 81.

[0054] like Figure 8-9 As shown, the bag pressing member 85 includes a pressure strip 851, a pin 852 and a torsion spring 853. The pin 852 is symmetrically installed on both sides of the pressure strip 851 near one end. The torsion spring 853 is sleeved on the pin 852. The groove wall of the strip groove 84 is provided with a groove for accommodating the torsion spring 853. The end of the pin 852 is rotatably connected to the bottom of the groove.

[0055] It should be noted that when the pressing cylinder 81 is not pressed down, the length direction of the pressing strip 851 is perpendicular to the bottom of the strip groove 84, and the pressing cylinder 81 is pressed down and sleeved on the packing cylinder 32 ( Figure 3 As shown in the figure, the pin shaft 852 is used to make the pressure strip 851 adaptively deflected into the strip groove 84. When the pressure cylinder 81 rises and resets, the torsion spring 853 is used to facilitate the deflection and reset of the pressure strip 851.

[0056] like Figure 1-2 As shown, a tamping rod 9 is provided above the conveyor belt 31 near the end, and a "7"-shaped fixing plate 10 is installed on the top of the tray 4 near the edge. A third cylinder 11 for controlling the lifting and lowering of the tamping rod 9 is installed on the fixing plate 10.

[0057] It should be noted that when the wrapping paper 2 on the packing tube 32 is folded toward the center ( Figure 3 As shown in the figure, the ramming rod 9 moves to the position just below the ramming rod 9, and starting the third cylinder 11 enables the ramming rod 9 to ram the wrapping paper 2 located outside the baling tube 32 after closing into the baling tube 32. In this embodiment, the ramming rod 9 can be inserted into the oil seal, so that the ramming rod 9 can cover the inner side of the oil seal when ramming into the wrapping paper 2, thereby realizing the overall packaging of the oil seal.

[0058] A packaging method for oil seal packaging equipment, comprising the following steps:

[0059] S1: The oil seals to be packaged are transported in an orderly manner by using the vibration plate 1, and the inner gear ring 61 is driven to rotate equidistantly by the driving mechanism 63, so that the oil seals are loaded into each receiving cylinder 621 in an orderly manner;

[0060] S2: The conveyor belt 31 drives the packing tube 32 to move below the first cylinder 641 and stops. The first cylinder 641 presses the receiving tube 621 loaded with the oil seal, so that the receiving tube 621 passes through the pressing hole 643 and presses the packaging paper 2 into the packing tube 32. Then, the receiving tube 621 rises and resets, so that the oil seal neatly falls into the packing tube 32 pressed with the packaging paper 2.

[0061] S3: Use the second air cylinder 7 to press down the pressing cylinder 81, and cooperate with the bag pressing member 85 to close the packaging paper 2 located outside the packing cylinder 32 toward the center of the pressing cylinder 81;

[0062] S4: The third cylinder 11 is used to drive the tamping rod 9 to be inserted into the packing tube 32 loaded with the oil seal, so that the closed packaging paper 2 is completely tamped into the packing tube 32 to achieve oil seal coverage, thereby completing the packing work of the oil seal.

[0063] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
