Technical Field

[0001] The utility model relates to the technical field of packaging equipment, and particularly relates to a flip - type laser coding device. Background Art

[0002] In order to enhance the anti - counterfeiting ability of products and the market supervision efficiency in factories, by adopting laser coding technology, precise control and efficient management of products can be achieved. According to the design of a small box product in the factory, laser coding is required on the back of the small box product for identification. Currently, for the existing equipment for packaging small box products of this specification, the outlet faces upwards, and manual feeding is required, resulting in low efficiency, unable to meet the production capacity requirements, and unable to achieve laser coding on the back. Content of the Utility Model

[0003] The purpose of the utility model is to provide a flip - type laser coding device to solve at least one of the above problems existing in the prior art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A flip - type laser coding device includes a frame. An inlet conveying mechanism, a first flipping mechanism, a middle pushing component, a second flipping mechanism, and an outlet pushing mechanism are sequentially arranged on the frame. A laser coding machine is arranged above the middle pushing component.

[0006] Both the first flipping mechanism and the second flipping mechanism include two relatively arranged turntables. The rotation axis of the turntable is perpendicular to the conveying direction of the inlet conveying mechanism. A plurality of die - box side guide plates are circumferentially and evenly arranged on the turntable. The die - box side guide plate includes an upper limit plate, a lower limit plate, and an end limit plate. The die - box side guide plates arranged oppositely on the two turntables form a die - box limiting structure. The inlet conveying mechanism conveys the small box product into the die - box limiting structure of the first flipping mechanism. The turntable of the first flipping mechanism rotates and flips the small box product to the feeding end of the middle pushing component. A box - pushing block is arranged on the conveyor belt of the middle pushing component. The box - pushing block pushes the small box product located at the feeding end of the middle pushing component out of the die - box limiting structure as the conveyor belt moves. When the middle pushing component conveys the small box product past the laser coding machine, the laser coding machine codes the small box product. Then, the middle pushing component conveys the laser - coded small box product into the die - box limiting structure of the second flipping mechanism. The turntable of the second flipping mechanism rotates and flips the coded small box product to the outlet pushing mechanism and is pushed out by the outlet pushing mechanism.

[0007] In this technical solution, the inlet conveying mechanism is mainly used to convey the small box products with the front side facing up to the first flipping mechanism. The first flipping mechanism flips the small box products so that the back side of the small box products faces up, facilitating laser coding on the back side of the small box products. Since the die box limiting structure is provided on the first flipping mechanism, during the rotation of the turntable, the upper limiting plate, lower limiting plate, and end limiting plate of the die box limiting structure can limit the three end faces of the small box products, and will not hinder the transfer of the small box products. That is, it is convenient to transfer the small box products into the die box limiting structure and also convenient to cooperate with the box pushing block to push the small box products out of the die box limiting structure. After the small box products are conveyed by the inlet conveying mechanism into the die box limiting structure on the turntable, the turntable of the first flipping mechanism rotates 180 degrees to complete the flipping of the small box, making the back side of the small box products face up. In this state, the box pushing block on the conveyor belt of the middle pushing component pushes the small box products out of the die box limiting structure so that the small box products fall onto the middle pushing component, and the middle pushing component continues to convey the small box products to move until the small box products are located below the laser coder. At this time, the laser coder codes the back side of the small box products. Since the middle pushing component has a box pushing block, the box pushing block can push the laser-coded small box products into the die box limiting structure of the second flipping mechanism. The turntable of the second flipping mechanism rotates and flips the coded small box products to the outlet pushing mechanism. At this time, the small box products return to the state with the front side facing up, and the outlet pushing mechanism pushes the small box products to the next process. In summary, this technical solution can achieve the flipping of the small box products so as to perform laser coding on the back side of the small box products, and can restore the coded small box products to the state with the front side facing up, and can quickly complete the flipping and laser coding of the small box products, solving the problem that the existing equipment for packaging small box products of this specification has the outlet facing up and cannot achieve laser coding on the back side.

[0008] Further, in order to better realize the pushing of the small box products, both the middle pushing component and the outlet pushing mechanism include a conveyor belt, guide plates, and box pushing blocks. The box pushing blocks are arranged on the conveyor belt, the guide plates are symmetrically arranged on both sides of the conveyor belt, and the box pushing blocks push the small box products to move on the guide plates.

[0009] During the process of the conveyor belt of the middle pushing component driving the box pushing blocks to move, it can push the small box products out from the left side of the die box limiting structure of the first flipping mechanism and make them fall on the guide plates. The guide plates can support the small box products, and the box pushing blocks can continue to move to continuously push the small box products located on the guide plates forward until the small box products move to the die box limiting structure of the second flipping mechanism. At this time, it can smoothly push the small box products into the die box limiting structure from the left side of the die box limiting structure of the second flipping mechanism, so that the second flipping mechanism can flip the small box products again. The box pushing blocks of the outlet pushing mechanism can push the small box products located in the die box limiting structure of the second flipping mechanism out in the same way and then convey them to the next process.

[0010] Further, in order to facilitate the smooth docking with the output of the packaging equipment and stably convey the small box products into the die box limiting structure of the first flipping mechanism, the inlet conveying mechanism includes a channel bottom plate, and inlet pushing components are symmetrically arranged on both sides of the channel bottom plate. A pressing plate and a box pressing component are arranged above the channel bottom plate. The pressing plate is arranged along the length direction of the channel bottom plate, and the box pressing component is located between the pressing plate and the first flipping mechanism;

[0011] The inlet pushing component includes a first synchronous pulley, a second synchronous pulley, and a third synchronous pulley. A first synchronous belt is sleeved on the first synchronous pulley, the second synchronous pulley, and the third synchronous pulley. The first synchronous belt between the first synchronous pulley and the second synchronous pulley is located on both sides of the channel bottom plate. The small box products located on the channel bottom plate are conveyed forward into the die box limiting structure of the first flipping mechanism through the first synchronous belts on both sides.

[0012] The channel bottom plate can maintain the docking with the output end of the packaging equipment. The first synchronous belt between the first synchronous pulley and the second synchronous pulley is located on both sides of the channel bottom plate. The small box products located on the channel bottom plate are conveyed forward into the die box limiting structure of the first flipping mechanism through the first synchronous belts on both sides. During this process, the setting of the pressing plate and the box pressing component can improve the stability of the conveyance of the small box products.

[0013] Further, in order to ensure the tension state of the synchronous belts on both sides and improve the stability of the conveyance, the inlet pushing component includes a mounting plate. The first synchronous pulley, the second synchronous pulley, and the third synchronous pulley are mounted on the mounting plate, and the mounting position of the third synchronous pulley on the mounting plate is adjustable.

[0014] Further, in order to improve the synchronous conveyance effect of the synchronous belts on both sides, the inlet conveying mechanism includes a bottom plate, a first motor, a fourth synchronous pulley, a fifth synchronous pulley, a sixth synchronous pulley, a seventh synchronous pulley, an eighth synchronous pulley, and a second synchronous belt. The mounting plate is arranged on the bottom plate. The first motor drives the fourth synchronous pulley to rotate. The second synchronous belt is sequentially wound around the fourth synchronous pulley, the fifth synchronous pulley, the sixth synchronous pulley, the seventh synchronous pulley, and the eighth synchronous pulley. The sixth synchronous pulley and the eighth synchronous pulley are respectively coaxially mounted at the lower ends of the corresponding first synchronous pulleys, and the mounting positions of the fifth synchronous pulley and the seventh synchronous pulley on the bottom plate are adjustable.

[0015] Further, in order to adjust the pressing effect of the pressing plate and the box pressing component as needed, the height positions of the pressing plate and the box pressing component are adjustable.

[0016] Further, in order to provide an elastic pressing effect and ensure the smoothness of the conveyance, the box pressing component includes a connecting plate. An installation seat is arranged at the lower end of the connecting plate. An elastic pressing piece is arranged on the installation seat, and a pressing wheel is arranged at the free end of the elastic pressing piece.

[0017] Furthermore, in order to improve the stability of the transfer during the flipping process of the small box product and prevent the small box product from slipping out of the outer side of the die box limiting structure, a first arc-shaped guard plate and a second arc-shaped guard plate are respectively provided on the frame. The first arc-shaped guard plate and the second arc-shaped guard plate are coaxially arranged outside the turntables of the first flipping mechanism and the second flipping mechanism. During the rotation of the turntable, the outer ends of the small box products located within the die box limiting structure come into contact with the inner sides of the first arc-shaped guard plate and the second arc-shaped guard plate.

[0018] Furthermore, the middle pushing assembly includes a middle pushing synchronous pulley, which drives the conveyor belt of the middle pushing assembly to move. The outlet pushing mechanism includes a pushing synchronous pulley, which drives the conveyor belt of the outlet pushing mechanism to move. A second motor is provided inside the frame, and the second motor drives the middle pushing synchronous pulley and the pushing synchronous pulley to rotate respectively through synchronous belt pulleys. With the above design, after the second motor is started, the middle pushing assembly and the outlet pushing mechanism can be started synchronously.

[0019] Furthermore, there are four workstations between the two relatively arranged turntables, and a die box limiting structure is provided at each workstation. The small box products are placed between the relatively arranged die box side guide plates, and the flipping of the small boxes is completed through the synchronous intermittent rotational movement of the relatively arranged turntables.

[0020] The beneficial effects of the present utility model are as follows: In this technical solution, the inlet conveying mechanism is mainly used to convey the small box products with the front side facing up to the first flipping mechanism. The first flipping mechanism flips the small box products so that the back side of the small box products faces up, facilitating laser coding on the back side of the small box products. Since the die box limiting structure is provided on the first flipping mechanism, during the rotation of the turntable, the upper limiting plate, lower limiting plate, and end limiting plate of the die box limiting structure can limit the three end faces of the small box products, and will not hinder the transfer of the small box products. That is to say, it is convenient to transfer the small box products into the die box limiting structure and also convenient to cooperate with the box pushing block to push the small box products out of the die box limiting structure. After the small box products are conveyed from the inlet conveying mechanism into the die box limiting structure on the turntable, the turntable of the first flipping mechanism rotates 180 degrees to complete the flipping of the small box, making the back side of the small box products face up. In this state, the box pushing block on the conveyor belt of the middle pushing component pushes the small box products out of the die box limiting structure, causing the small box products to fall onto the middle pushing component, and the middle pushing component continues to convey the small box products until the small box products are located below the laser coder. At this time, the laser coder codes the back side of the small box products. Since the middle pushing component has a box pushing block, the box pushing block can push the laser-coded small box products into the die box limiting structure of the second flipping mechanism. The turntable of the second flipping mechanism rotates and flips the coded small box products to the outlet pushing mechanism. At this time, the small box products return to the state with the front side facing up, and the outlet pushing mechanism pushes the small box products to the next process. In summary, this technical solution can achieve the flipping of the small box products, so as to enable laser coding on the back side of the small box products, and can restore the coded small box products to the state with the front side facing up, and can quickly complete the flipping and laser coding of the small box products, solving the problem that the existing equipment for packaging small box products of this specification has the outlet facing up and cannot achieve laser coding on the back side.

Specific embodiments

[0030] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the present utility model in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained according to these drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model.

[0031] Embodiment 1:

[0032] As Figures 1 - 8 shown, this embodiment provides a flip-type laser coding device, including a frame 1, on which an inlet conveying mechanism 2, a first flipping mechanism 3, a middle pushing component 4, a second flipping mechanism 5 and an outlet pushing mechanism 6 are sequentially arranged, and a laser coding machine 7 is arranged above the middle pushing component 4;

[0033] Both the first flipping mechanism 3 and the second flipping mechanism 5 include two relatively arranged turntables 8, the rotation axis of the turntable 8 is perpendicular to the conveying direction of the inlet conveying mechanism 2, and a plurality of die box side guide plates are circumferentially and evenly arranged on the turntable 8, as Figure 6As shown in the figure, the side guide plate of the mold box includes an upper limit plate 9, a lower limit plate 10, and an end limit plate 11. The side guide plates of the mold box arranged oppositely on the two turntables 8 form a mold box limit structure. The inlet conveying mechanism 2 conveys the small box products into the mold box limit structure of the first flipping mechanism 3. The turntable 8 of the first flipping mechanism 3 rotates and flips the small box products to the feeding end of the middle pushing component 4. There is a box pushing block 13 on the conveyor belt 12 of the middle pushing component 4. As the conveyor belt 12 moves, the box pushing block 13 pushes the small box products located at the feeding end of the middle pushing component 4 out of the mold box limit structure. When the middle pushing component 4 conveys the small box products past the laser coding machine 7, the laser coding machine 7 codes the small box products. Then, the middle pushing component 4 conveys the laser-coded small box products into the mold box limit structure of the second flipping mechanism 5. The turntable 8 of the second flipping mechanism 5 rotates and flips the coded small box products to the outlet pushing mechanism 6, and the outlet pushing mechanism 6 pushes them out.

[0034] In this technical solution, the inlet conveying mechanism 2 is mainly used to convey the small box products with the front side facing up to the first flipping mechanism 3. The first flipping mechanism 3 flips the small box products so that the back side of the small box products faces up, which is convenient for laser coding the back side of the small box products. Since there is a mold box limit structure on the first flipping mechanism 3, during the rotation of the turntable 8, the upper limit plate 9, the lower limit plate 10, and the end limit plate 11 of the mold box limit structure can limit the three end faces of the small box products and will not hinder the transfer of the small box products. That is to say, it is convenient to transfer the small box products into the mold box limit structure and also convenient to cooperate with the box pushing block 13 to push the small box products out of the mold box limit structure. After the small box products are conveyed by the inlet conveying mechanism 2 into the mold box limit structure on the turntable 8, the turntable 8 of the first flipping mechanism 3 rotates 180 degrees to complete the flipping of the small box, making the back side of the small box products face up. In this state, the box pushing block 13 on the conveyor belt 12 of the middle pushing component 4 pushes the small box products out of the mold box limit structure so that the small box products fall onto the middle pushing component 4, and the middle pushing component 4 continues to convey the small box products to move until the small box products are located below the laser coding machine 7. At this time, the laser coding machine 7 codes the back side of the small box products. Since the middle pushing component 4 has a box pushing block 13, the box pushing block 13 can push the laser-coded small box products into the mold box limit structure of the second flipping mechanism 5. The turntable 8 of the second flipping mechanism 5 rotates and flips the coded small box products to the outlet pushing mechanism 6. At this time, the small box products return to the state with the front side facing up, and the outlet pushing mechanism 6 pushes the small box products to the next process. In summary, this technical solution can flip the small box products so as to be able to laser code the back side of the small box products, and can restore the laser-coded small box products to the state with the front side facing up, and can quickly complete the flipping and laser coding of the small box products, solving the problem that the existing equipment for packaging small box products of this specification has the outlet with the front side facing up and cannot achieve laser coding on the back side.

The box pushing block 13 is arranged on the conveyor belt 12, the guide plates 14 are symmetrically arranged on both sides of the conveyor belt 12, and the box pushing block 13 pushes the small box products to move on the guide plate 14.

[0038] During the process of the conveyor belt 12 of the middle pushing component 4 driving the box pushing block 13 to move, the small box products can be pushed out from the left side of the die box limiting structure of the first flipping mechanism 3 and fall on the guide plate 14. The guide plate 14 can support the small box products. The box pushing block 13 continues to move to continuously push the small box products located on the guide plate 14 forward. When the small box products move to the die box limiting structure of the second flipping mechanism 5, the small box products can be smoothly pushed into the die box limiting structure from the left side of the die box limiting structure of the second flipping mechanism 5 so that the second flipping mechanism 5 can flip the small box products again.
