Description

Technical Field

[0001] The invention relates to the technical field of wheel hub protection ring packaging, in particular to a packaging device for an L-shaped wheel hub protection ring adapted to different surfaces based on automatic flanging. Background Art

[0002] There are two types of wheel hub protection rings. One is attached to the outer ring of the wheel hub to protect the car's wheel hub and prevent the wheel hub from being scratched during driving. The other is put on the outer ring of the wheel hub after the wheel hub is produced to prevent the wheel hub from being bumped or dented during transportation.

[0003] Common wheel hub guards are divided into T-type and L-type. For example, the Chinese patent with announcement number CN203903082U discloses a T-type wheel hub guard. The T-type wheel hub guard is usually used to separate two wheel hubs stacked together to prevent the two wheel hubs from being scratched by friction during transportation. The L-type wheel hub guard is usually used to protect a single wheel hub to prevent the wheel hub from being scratched by external objects.

[0004] During the production process of L-shaped wheel hub protection rings, since the L-shaped wheel hub protection rings are in an asymmetric structure, it is necessary to distinguish the front and back sides. In order to ensure the uniformity of packaging, the L-shaped wheel hub protection rings need to be flanged during the packaging process so that when multiple L-shaped wheel hub protection rings are packaged together, they are all in a state of facing up. However, most of them are currently manually observed and the L-shaped wheel hub protection rings with the back side facing up are manually flanged, which increases the labor of manual labor.

[0055] See also Figure 1 As shown, a packaging device for an L-shaped wheel hub protection ring based on automatic flanging to adapt to different surfaces is provided, comprising a workbench 100, a top of the workbench 100 is provided with a blanking opening 101 with a diameter larger than that of the wheel hub protection ring 200 on the moving path of the wheel hub protection ring 200; an opening and closing mechanism 120 is provided at the bottom of the blanking opening 101, and a placement area 102 for placing a packaging box 103 is formed below; as shown Figure 2 As shown, the opening and closing mechanism 120 includes a baffle plate 122 rotatably arranged at the bottom of the material drop opening 101, and the baffle plate 122 has a blocking state and a releasing state; in addition, the packaging device also includes a sensing mechanism 150 located on one side of the moving direction of the wheel hub protection ring 200, such as Figure 6 As shown, the sensing mechanism 150 includes a detection rod 152 that can be extended into the interior of the wheel hub protection ring 200, and a driving part connected to the detection rod 152; the driving part controls the baffle plate 122 to switch between a blocking state and a releasing state according to the state in which the detection rod 152 is extended into the interior of the wheel hub protection ring 200; then, in the blocking state, the baffle plate 122 is located below the blanking port 101, and is used to block the wheel hub protection ring 200 at the top of the blanking port 101 from falling; in the releasing state, the baffle plate 122 is detached from the bottom of the blanking port 101, and is used to make the wheel hub protection ring 200 at the top of the blanking port 101 fall into the packaging box 103; and, a flipping mechanism 110 is provided at one end of the workbench 100, and after the wheel hub protection ring 200 passes through the blanking port 101, the flipping mechanism 110 flips the wheel hub protection ring 200, and guides the flipped wheel hub protection ring 200 into the packaging box 103.

[0056] That is to say, the detection rod 152 senses the front and back sides of the wheel hub protection ring 200 to control the material blocking plate 122, so that the wheel hub protection ring 200 on the front side enters the packaging box 103 through the blanking port 101, and the wheel hub protection ring 200 on the back side is flipped to the front side through the flipping mechanism 110 and then enters the packaging box 103, thereby achieving the unification of multiple wheel hub protection rings 200 in the packaging box 103 without the need for manual assisted flipping, so as to reduce manual labor.

[0057] In the above, the specific structure of the flip mechanism 110 is as follows Figure 1 As shown. In some embodiments, the flip mechanism 110 includes a pipe fixedly arranged at one end of the workbench 100 and in a "C" shape, the width of the pipe is greater than the diameter of the wheel hub protection ring 200, so that the wheel hub protection ring 200 can pass through; at the same time, the upper end of the pipe is fixedly arranged at one end of the workbench 100, and the bottom inner wall of the upper end is kept flush with the surface of the top of the workbench 100, so that the wheel hub protection ring 200 on the top of the workbench 100 can enter the inside of the pipe through the upper end of the pipe; the lower end of the pipe is located on one side of the packaging box 103 and faces the inside of the packaging box 103. In this way, after the wheel hub protection ring 200 located at the top of the workbench 100 enters the inside of the pipe through the upper end of the pipe, it is flipped by using the "C" shape of the pipe, so that the flipped wheel hub protection ring 200 faces up. After the flip is completed, the wheel hub protection ring 200 slides into the packaging box 103 through the lower end of the pipe.

[0058] In addition, convex strips are provided on both sides of the hub protection ring 200 at the top of the workbench 100 for limiting the hub protection ring 200 so that the hub protection ring 200 can only move in a straight line.

[0059] The front and back sides of the wheel hub protection ring 200 are as follows Figure 7 and Figure 8 Specifically, Figure 7 The wheel hub protection ring 200 is at the front. Figure 8 The wheel hub protection ring 200 is on the reverse side.

[0060] Figure 3 and Figure 4 The specific structure of the opening and closing mechanism 120 is shown. Figure 3 As shown, the opening and closing mechanism 120 also includes a square-shaped fixed frame 121; the baffle plates 122 are opposite to the two ends of the fixed frame 121, and the two sides of one end of the baffle plate 122 are fixedly provided with connecting shafts 123 that rotate and penetrate the fixed frame 121, and one end of one connecting shaft 123 is coaxially connected to a driven gear 124. Then, as shown in FIG. Figure 4As shown, a support spring 131 is provided between the fixing frame 121 and the workbench 100 to elastically connect the two, wherein a fixing plate 130 is fixedly provided at the bottom of the workbench 100, and the bottom end of the fixing plate 130 is bent below the fixing frame 121, and then the support spring 131 is provided between the bottom of the fixing frame 121 and the bent end of the fixing plate 130. In addition, the driven gear 124 has an initial state and a downward moving state, wherein when the support spring 131 is not compressed, the driven gear 124 is in the initial state; when the support spring 131 is compressed, the driven gear 124 is in the downward moving state.

[0061] Since the workbench 100 has a certain thickness and the baffle plate 122 is arranged at the bottom of the workbench 100, there is a height difference between the top of the baffle plate 122 and the top of the blanking port 101, which causes the wheel hub protection ring 200 to fall down to the top of the baffle plate 122 after moving into the blanking port 101, affecting the continued movement of the wheel hub protection ring 200. To this end, the top of the baffle plate 122 at the blanking port 101 protrudes upward to form a protrusion 125, and the top of the protrusion 125 is kept flush with the top of the workbench 100, thereby preventing the wheel hub protection ring 200 from falling down after moving into the blanking port 101.

[0062] exist Figure 1 and Figure 2 In the embodiment, the driving part includes a screw rod 140 located on both sides of the moving direction of the workbench 100, a driving gear 142 coaxially fixedly connected to one end of the screw rod 140, and a push rod 143 for pushing the sensing mechanism 150. Among them, the driving gear 142 is meshed with the driven gear 124 in the initial state; one end of the push rod 143 is threadedly connected to the screw rod 140. Specifically, both ends of the screw rod 140 are rotatably connected to a shaft seat fixedly set on the top of the workbench 100, and one end of the screw rod 140 is coaxially connected to a motor 141 fixedly set on the workbench 100. The driving gear 142 is located at one end of the screw rod 140 close to the blanking port 101.

[0063] In order to prevent the push rod 143 from rotating with the screw rod 140, the prior art currently discloses some implementation methods. For example, a round rod penetrating the push rod 143 is arranged around the screw rod 140, and the round rod limits the push rod 143, which can prevent the push rod 143 from rotating with the screw rod 140. For another example, the bottom of one end of the push rod 143 that is threadedly connected to the screw rod 140 has a plane, and the plane contacts the top of the workbench 100, so as to limit the push rod 143 and prevent the push rod 143 from rotating with the screw rod 140. Therefore, the present invention is not limited here.

[0064] When the screw rod 140 drives the push rod 143 to move toward the blanking port 101, the driving gear 142 coaxially connected to the screw rod 140 drives the baffle plate 122 to rotate upward through the driven gear 124. However, since the baffle plate 122 is located at the bottom of the blanking port 101, it cannot continue to rotate upward. Figure 5 As shown, a cavity 132 is provided inside the driven gear 124, and a plurality of grooves 133 are provided on the outer ring of the cavity 132; one end of the connecting shaft 123 is inserted into the cavity 132 in a rotatable manner, and a plurality of elastic plates 134 are fixedly provided on the outer ring of the connecting shaft 123 located in the cavity 132, one end of which is inserted into the groove 133.

[0065] like Figure 6 As shown, the sensing mechanism 150 also includes a driven rod 151 with one end fixedly connected to the top of the detection rod 152 and the other end longitudinally slidably connected to the slider 155, and a force plate 126 fixedly set on the top of the fixing frame 121; wherein the detection rod 152 is located above the bent end of the hub protection ring 200, and the bottom is provided with a hypotenuse higher than the hub protection ring 200. When the hub protection ring 200 passes through the detection rod 152, the detection rod 152 uses the hypotenuse to make an up and down movement corresponding to the structure of the hub protection ring 200. Then, the outer ring of the slider 155 is laterally slidably connected to the side plate 156 fixedly set on one side of the workbench 100. Next, a driving rod 153 is fixedly provided at the bottom end of the driven rod 151 and is located directly above the force-bearing plate 126. The driving rod 153 is used to drive the force-bearing plate 126 to move downward through the push rod 143; when the detection rod 152 moves downward, the driven rod 151 is located in the driving path of the push rod 143; when the detection rod 152 moves upward, the driven rod 151 is disengaged from the driving path of the push rod 143.

[0066] Specifically, a longitudinal slideway is provided through the side wall of the slider 155, and one end of the driven rod 151 penetrates into the slideway and is slidably connected with the slideway. A slide groove 157 is provided through the side wall of the side plate 156, and the slider 155 is slidably arranged in the slide groove 157, and a return spring 158 is provided between one side of the slider 155 and one end of the slide groove 157 to elastically connect the two. Under normal conditions, the return spring 158 presses the slider 155 against one end of the slide groove 157. After the slider 155 moves, the return spring 158 provides the slider 155 with power to return to one end of the slide groove 157.

[0067] The bevel at the bottom of the detection rod 152 is to ensure that the hub protection ring 200 can be driven to move up and down by the bevel during the movement of the detection rod 152, so as to avoid the detection rod 152 affecting the movement of the hub protection ring 200. At the same time, it can also realize the judgment of the front and back sides of the hub protection ring 200. Its specific structure is as follows Figure 6As shown, a V-shaped inclined plate 154 is fixedly provided at the bottom of the detection rod 152. The height of the inclined plate 154 is higher than the wheel hub protection ring 200, and the outer walls on both sides form bevel edges.

[0068] Figure 3 and Figure 7 The specific structure of the force plate 126 is shown. As shown in the figure, the force plate 126 is arranged to penetrate the workbench 100 in the longitudinal direction, and the top of the force plate 126 is sequentially provided with a low surface 127, an inclined surface 128 and a high surface 129, wherein the high surface 129 is arranged close to the flip mechanism 110 (refer to Figure 1 ). And, when the detection rod 152 moves downward, the bottom end of the driving rod 153 abuts between the lower surface 127 and the inclined surface 128.

[0069] Working principle:

[0070] First, a material pushing structure is arranged at one end of the workbench 100 away from the flipping mechanism 110, for example, the material pushing structure is a cylinder, and the cylinder is fixed on the top of the workbench 100, and then the wheel hub protection ring 200 is placed on the top of the workbench 100, and then the cylinder is started, and the movable end of the cylinder pushes the wheel hub protection ring 200 toward the flipping mechanism 110. When the wheel hub protection ring 200 moves to the blanking port 101, since the material blocking plate 122 is located at the bottom of the blanking port 101, it plays a supporting role for the wheel hub protection ring 200, and at this time, the wheel hub protection ring 200 will not fall down through the blanking port 101.

[0071] Then, if Figure 7 and Fig.10 As shown, when the wheel hub protection ring 200 is Figure 7 When the wheel hub protection ring 200 moves to the blanking port 101, the side wall in front of the wheel hub protection ring 200 will push the detection rod 152 upward through the inclined plate 154, and the detection rod 152 moves upward to drive the driven rod 151 and the driving rod 153 to move upward. As the wheel hub protection ring 200 continues to move, the detection rod 152 is now inside the wheel hub protection ring 200, but because the bent end of the wheel hub protection ring 200 is located at the bottom, the bottom of the detection rod 152 is not supported at this time, causing the bottom end of the detection rod 152 to move down to the bottom inner wall of the wheel hub protection ring 200, and the detection rod 152 drives the driven rod 151 and the driving rod 153 to move down. After the driving rod 153 moves down, it is located between the lower surface 127 and the inclined surface 128.

[0072] Then, the motor 141 is started, and the motor 141 drives the screw rod 140 to rotate, and the screw rod 140 rotates to drive the push rod 143 to move toward the driven rod 151. In this process, the screw rod 140 also drives the driving gear 142 to rotate, and the driving gear 142 rotates to drive the driven gear 124 to rotate. However, since the baffle plate 122 is located at the bottom of the blanking port 101 and cannot rotate upward, the driven gear 124 will be twisted and deformed when it rotates, so that the end of the elastic plate 134 is separated from the groove 133 and enters the next groove 133. In this way, the driven gear 124 will not affect the baffle plate 122 during the rotation process, and the screw rod 140 connected to the driving gear 142 can also rotate.

[0073] When the push rod 143 moves toward the driven rod 151, since the driven rod 151 is in a downward movement state at this time, the driven rod 151 is on the driving path of the push rod 143 (refer to Fig. 9 ), at this time, the push rod 143 pushes the driven rod 151 to move, the driven rod 151 moves and drives the driving rod 153 to move, the driving rod 153 moves and pushes the force plate 126 downward through the inclined surface 128, forcing the force plate 126 to drive the fixing frame 121 to move downward, and the support spring 131 is compressed. The fixing frame 121 moves downward and drives the driven gear 124 to move downward, and the driven gear 124 moves downward and disengages from the driving gear 142. At this time, Fig.11 As shown, under the action of gravity, the baffle plate 122 rotates downward, and after the baffle plate 122 rotates, it is separated from the bottom of the blanking opening 101. At this time, the hub protection ring 200 directly falls into the packaging box 103.

[0074] Then, if Figure 8 and Fig.12 As shown, when the wheel hub protection ring 200 is Figure 8 When the wheel hub protection ring 200 moves to the blanking port 101, the detection rod 152 cannot move downward because the bent end of the wheel hub protection ring 200 is located at the top. At this time, the driven rod 151 and the driving rod 153 are both in the upward state. Fig. 9 As shown, after the driven rod 151 moves upward, it is located above the push rod 143. At this time, the push rod 143 no longer contacts the driven rod 151 during the movement, so that the driven rod 151 cannot be pushed, and the force plate 126 will not move downward, and the blocking plate 122 will not rotate. At this time, the hub protection ring 200 cannot fall through the drop opening 101. Then, the hub protection ring 200 is further pushed by the cylinder to move the hub protection ring 200 to the flip mechanism 110, and after the flip mechanism 110 flips 180 degrees, it falls into the packaging box 103.

[0075] After the wheel hub protection ring 200 falls into the packaging box 103, the cylinder is reset, and then the motor 141 drives the screw rod 140 to rotate in the opposite direction, and the screw rod 140 reverses to drive the push rod 143 to reset. At the same time, the screw rod 140 drives the baffle plate 122 to rotate downward through the driving gear 142 and the driven gear 124. Since the baffle plate 122 is already in a downward state at this time, the elastic plate 134 will be twisted again. When the motor 141 drives the screw rod 140 to rotate forward again, the screw rod 140 drives the push rod 143 to move toward the blanking port 101, and drives the baffle plate 122 to rotate upward to the bottom of the blanking port 101 through the driving gear 142 and the driven gear 124, thereby realizing a cyclic operation.

[0076] Furthermore, in order to prevent the push rod 143 from pushing the driven rod 151 to move, the driving rod 153 moves upward through the inclined surface 128. Fig. 9 As shown, protrusions are provided on the adjacent sides of the driven rod 151 and the push rod 143. When the end of the push rod 143 moves to the side wall of the driven rod 151, the protrusions at the end of the push rod 143 will engage with the protrusions on the side wall of the driven rod 151, thereby avoiding the driven rod 151 from moving upward. At this time, the driving rod 153 located at the bottom of the driven rod 151 can drive the force plate 126 to move downward through the inclined surface 128.

[0077] In addition, in order to achieve rapid driving of the hub protection ring 200, as Figure 2 and Fig.10 As shown, a push plate 144 is provided between the two screw rods 140, and both ends of the push plate 144 are threadedly connected to the screw rods 140. When in use, the push plate 144 is first moved to the end of the workbench 100 away from the flip mechanism 110, and then the hub protection ring 200 is placed on the top of the workbench 100, and then the motor 141 drives the screw rod 140 to rotate, and at this time, the screw rod 140 simultaneously drives the push rod 143 and the push plate 144 to move toward the blanking port 101, and the push plate 144 moves to push the hub protection ring 200 toward the blanking port 101.

[0078] It can be seen that the push rod 143 can not only drive the push rod 143 to move during the rotation process, but also drive the wheel hub protection ring 200 through the push plate 144, so there is no need to set up an additional pushing mechanism for the wheel hub protection ring 200, which reduces the cost and improves the packaging efficiency of the wheel hub protection ring 200.
