Detailed implementation manner

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1. Please refer to Figures 1-11 The present invention discloses a handling device for packaging boxes used in food sales, including a conveyor belt 1 for transporting packaging cartons 11. An installation frame 12 is arranged on the conveyor belt 1, and both ends of the installation frame 12 are respectively fixed on the two conveyor belts 1, thereby facilitating the transfer of the packaging cartons 11 on the two conveyor belts 1. A sliding groove 14 is arranged inside the installation frame 12, a sliding block 15 is slidably connected in the sliding groove 14, a first sealing pipe 2 is fixedly connected below the sliding block 15, a first sliding rod 21 is slidably connected inside the first sealing pipe 2, the other end of the first sliding rod 21 is fixedly connected with a clamping rod 24, and first hydraulic rods 210 are arranged on both sides of the clamping rod 24. The power output end of the first hydraulic rod 210 passes through the clamping rod 24, and the power output end of the first hydraulic rod 210 is fixedly connected with a clamping plate 25. It is characterized in that: a fixed block 27 is fixedly connected to one side of the clamping plate 25, a second hydraulic rod 311 is arranged inside the fixed block 27, and a rotating shaft 3 is rotatably connected to one side of the fixed block 27. The other end of the rotating shaft 3 is fixedly connected with a fixed pipe 32. Through the design of the rotating shaft 3, the subsequent fixed pipe 32 can rotate through the rotating shaft 3. At the same time, through the design of the fixed block 27, stable support can be provided for the rotation of the rotating shaft 3. A sliding pipe 33 is slidably connected inside the fixed pipe 32, and a support rod 36 for supporting the bottom of the packaging carton 11 is slidably connected inside the sliding pipe 33.

[0031] One end of the mounting bracket 12 is provided with a power motor 13. The power output end of the power motor 13 is fixedly connected to a lead screw 16. The other end of the lead screw 16 is rotatably connected to the mounting bracket 12. The lead screw 16 is located in the sliding groove 14, and the lead screw 16 is threadedly connected to the sliding block 15. Through the design of the threaded connection between the lead screw 16 and the sliding block 15, when the lead screw 16 rotates, it can drive the sliding block 15 to slide in the sliding groove 14. At the same time, through the design of the sliding groove 14, it is convenient for the sliding block 15 to slide therein, and it can provide stable guidance for the sliding of the sliding block 15, preventing the subsequent sliding block 15 from shifting during the sliding process, and being able to provide a stable operating environment for the first sealing tube 2.

[0032] The lower end of the first sealing tube 2 is fixedly communicated with a liquid inlet pipe 22. The other end of the liquid inlet pipe 22 is communicated with a hydraulic pump 26. Through the design of the hydraulic pump 26, the hydraulic oil can have a certain pressure, so that the first sliding rod 21 can be jacked up. The upper end of the first sealing tube 2 is communicated with a pair of liquid outlet pipes 23.

[0033] When it is necessary to transfer the packaging carton 11 from the conveyor belt 1 to another conveyor belt 1, first start the power motor 13. The power motor 13 drives the lead screw 16 to rotate. Through the rotation of the lead screw 16, the sliding block 15 slides in the sliding groove 14. While the sliding block 15 slides, it drives the first sealing tube 2, the first sliding rod 21, the clamping rod 24, the first hydraulic rod 210 and the clamping plate 25 to slide together, so that the clamping plate 25 slides to the position of the packaging carton 11. Subsequently, start the first hydraulic rod 210. The first hydraulic rod 210 drives the clamping plate 25 to clamp the packaging carton 11, thereby clamping the packaging carton 11 tightly. Subsequently, start the hydraulic pump 26. The hydraulic pump 26 transports the hydraulic oil into the first sealing tube 2 through the liquid inlet pipe 22, see Figure 3 , and the first sliding rod 21 is jacked up by the hydraulic oil, so that the first sliding rod 21 slides upward in the first sealing tube 2. While the first sliding rod 21 slides upward, it drives the clamping rod 24, the clamping plate 25 and the clamped packaging carton 11 to slide upward together, so that the packaging carton 11 can be lifted.

[0034] In this embodiment: Through the mutual cooperation among the sliding groove 14, the sliding block 15 and the lead screw 16, the sliding block 15 can slide stably in the sliding groove 14. After the packaging carton 11 is lifted, when the sliding block 15 slides to drive the first sealing tube 2, the first sliding rod 21, the clamping rod 24 and the clamping plate 25 to slide, it can be more stable. When transferring the packaging carton 11 on the conveyor belt 1 to another conveyor belt 1, the packaging carton 11 will not fall due to jitter during the transfer process, making the packaging carton 11 more stable during the transfer process.

[0035] Example 2. This example aims to facilitate the solution of the problem that after the packaging carton 11 is clamped, the packaging carton 11 may contain heavy items inside, resulting in the packaging carton 11 being pressed open. This example is an improvement based on Example 1. Specifically, please refer to Figures 1-11 , the liquid outlet pipe 23 is fixedly connected to a sealing chamber 28. The liquid outlet pipe 23 penetrates through the clamping rod 24, and the liquid outlet pipe 23 passes through the fixing block 27 and is fixedly connected to the sealing chamber 28. The sealing chamber 28 is arc-shaped and is located within the fixing block 27. The other end of the sealing chamber 28 is fixedly connected to a pipe 29. A sealing block 31 is slidably connected within the sealing chamber 28. The sealing block 31 is fixedly installed on the rotating shaft 3. Through this design, when the sealing block 31 slides within the sealing chamber 28, it can drive the rotating shaft 3 to rotate together.

[0036] The pipe 29 is fixedly connected to a second sealing pipe 38. The second sealing pipe 38 is fixedly installed inside the fixed pipe 32. A second sliding rod 39 is slidably connected within the second sealing pipe 38. The other end of the second sliding rod 39 is fixedly connected to the outer side of the sliding pipe 33. Through this design, when the hydraulic oil enters the second sealing pipe 38, it can drive the second sliding rod 39 to slide, so that the second sliding rod 39 can drive the sliding pipe 33 to slide together.

[0037] A first rack 35 is fixedly connected inside the fixed pipe 32. One side of the first rack 35 is meshed with a transmission gear 34. The transmission gear 34 is rotatably connected to the sliding pipe 33. A pair of guiding straight chutes 4 and guiding inclined chutes 44 are provided inside the sliding pipe 33. The guiding straight chutes 4 communicate with the guiding inclined chutes 44.

[0038] The other side of the transmission gear 34 is meshed with a second rack 37. The second rack 37 is fixedly installed on one side of the support rod 36. Through the cooperation among the transmission gear 34, the first rack 35 and the second rack 37, the sliding pipe 33 and the support rod 36 can slide more smoothly.

[0039] See Figure 3 , when the hydraulic oil enters the first sealing pipe 2 through the liquid inlet pipe 22, the hydraulic oil pushes the first sliding rod 21 to slide upward within the first sealing pipe 2. When the first sliding rod 21 slides upward within the first sealing pipe 2, it will squeeze the original hydraulic oil within the first sealing pipe 2, so that the hydraulic oil within the first sealing pipe 2 is squeezed into the liquid outlet pipes 23 on both sides. As the hydraulic oil continues to be delivered into the first sealing pipe 2 through the liquid inlet pipe 22, the hydraulic oil within the first sealing pipe 2 is also continuously squeezed into the liquid outlet pipes 23. See Figure 4, the hydraulic oil in the liquid outlet pipe 23 will be conveyed into the sealed chamber 28, causing the hydraulic oil to squeeze the sealing block 31, so that the sealing block 31 slides in the sealed chamber 28. While the sealing block 31 slides in the sealed chamber 28, the rotating shaft 3 is driven to rotate by the sealing block 31; while the rotating shaft 3 rotates, the fixed pipe 32 is driven to rotate together. While the fixed pipe 32 rotates, the sliding pipe 33 and the support rod 36 are also driven to rotate together. Through the rotation of the fixed pipe 32, the support rod 36 can be aligned with the lower part of the packaging carton 11. When the rotating shaft 3 drives the fixed pipe 32 to rotate to a specific position, at this time the sealing block 31 slides past the pipe 29, enabling the pipe 29 to communicate with the sealed chamber 28, so that the hydraulic oil can enter the pipe 29. Through such a design, when the packaging carton 11 is clamped and lifted, the fixed pipe 32 can be rotated to a state perpendicular to the packaging carton 11, preparing for the subsequent sliding of the support rod 36 towards the bottom of the packaging carton 11; at the same time, when the sealing block 31 slides to a specific position, at this time the second hydraulic rod 311 is activated, and the power output end of the second hydraulic rod 311 slides into the fixing hole 310, so that the positions of the sealing block 31 and the rotating shaft 3 can be fixed, realizing the fixation of the fixed pipe 32, making the subsequent support for the bottom of the packaging carton 11 more stable.

[0040] It should be noted that when the subsequent equipment needs to be reset, after the fixed pipe 32, the sliding pipe 33 and the support rod 36 are all reset, the second hydraulic rod 311 will slide the power output end out of the fixing hole 310. During suction at 26, the hydraulic oil in the sealed chamber 28 can be pumped out, enabling the sealing block 31 to slide back, preventing the situation where when the fixed pipe 32 rotates back to its original position, the sliding pipe 33 and the support rod 36 are not reset.

[0041] After the hydraulic oil enters the pipe 29, it will enter the second sealing pipe 38 under the continuous conveyance of the hydraulic oil. After the hydraulic oil enters the second sealing pipe 38, it will push the second sliding rod 39 in the second sealing pipe 38 to slide. Through the sliding of the second sliding rod 39, the sliding pipe 33 is driven to slide together. While the sliding pipe 33 slides, the support rod 36 in the sliding pipe 33 can also slide together; See Figure 7When the sliding tube 33 slides, it will also drive the transmission gear 34 to slide to the right. By driving the transmission gear 34 to slide, under the action of the first rack 35, the transmission gear 34 will rotate. When the transmission gear 34 rotates, it will drive the second rack 37 on the other side to slide, so that the second rack 37 can drive the support rod 36 to slide to the right. Through such a design, the support rod 36 can slide to the right with the sliding tube 33, and can also perform a secondary sliding with the cooperation of the transmission gear 34, the first rack 35 and the second rack 37, so that the support rod 36 can slide farther, so that the support rod 36 can support the bottom of the packaging carton 11 as much as possible.

[0042] It should be noted that support rods 36 are provided on the clamping plates 25 on both sides to support the bottom of the packaging carton 11, and the support rods 36 on both sides are staggered and staggered, so that the two support rods 36 will not collide after extending, and at the same time can increase the supporting area under the packaging carton 11.

[0043] In this embodiment: by clamping the packaging carton 11 and then rotating the fixed tube 32, the sliding tube 33 and the support rod 36, it is possible to prevent the support rod 36 from colliding with the conveyor belt 1 when it is extended, so that the packaging carton 11 is supported by the support rod 36 after being clamped, and at the same time, by the design of two-level transmission between the fixed tube 32, the sliding tube 33 and the support rod 36, the support rod 36 can be extended further, which can increase the support area of ​​the support rod 36 under the packaging carton 11; Moreover, through the staggered design between the support rods 36 on both sides, the supporting area under the packaging carton 11 can be increased. At the same time, through the design of the two support rods 36 supporting, the support rods 36 can also support the bottom of the packaging carton 11 more evenly, preventing the problem of unstable support center of gravity, further improving the support for the bottom of the packaging carton 11, increasing the compressive strength of the packaging carton 11, and preventing the packaging carton 11 from being deformed and damaged due to excessive pressure during the transfer process.

[0044] Embodiment 3: This embodiment is intended to promote the solution of the problem that the contact area between the support rod 36 and the packaging carton 11 is small. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1-11 A pair of control rods 42 are slidably connected inside the support rod 36, and one end of the control rod 42 is fixedly connected to a sliding column 41. The sliding column 41 is slidably connected to the guiding straight slide groove 4 and the guiding inclined slide groove 44. Through the design of the sliding connection between the sliding column 41 and the guiding straight slide groove 4 and the guiding inclined slide groove 44, the position of the sliding column 41 and the control rod 42 can also be restricted to prevent the sliding column 41 and the control rod 42 from sliding without reason.

[0045] A plurality of support blocks 43 are provided on the control rod 42. The support blocks 43 are located inside the support rod 36, and the support blocks 43 are slidably connected to the support rod 36. The support blocks 43 are used to increase the contact area with the bottom of the packaging carton 11; When the sliding column 41 is located in the guiding inclined chute 44, the support block 43 slides out of the support rod 36. Through the design of the sliding column 41, the control rod 42 and the support block 43, when the bottom of the packaging carton 11 does not need to be supported, the support block 43 can contract into the interior of the support rod 36, facilitating the sliding of the support rod 36 in the sliding tube 33. At the same time, when the bottom of the packaging carton 11 needs to be supported, the support block 43 can slide out of the support rod 36, increasing the flexibility of the support.

[0046] While the support rod 36 is sliding, it will drive the sliding column 41 inside the support rod 36 to slide together, enabling the sliding column 41 to slide in the guiding straight chute 4 and the guiding inclined chute 44. When the sliding column 41 slides from the guiding straight chute 4 into the guiding inclined chute 44, the guiding of the guiding inclined chute 44 will cause the sliding column 41 to slide towards both sides of the support rod 36. While the sliding column 41 is sliding, it will drive the control rod 42 to slide together. Through the sliding of the control rod 42, it will drive the support block 43 to slide outwards of the support rod 36 together, enabling the support blocks 43 on both sides of the support rod 36 to slide out of the support rod 36, thereby increasing the contact area with the bottom of the packaging carton 11, making the bottom of the packaging carton 11 more stably supported. Through such a design, the pressure on the bottom of the packaging carton 11 can be dispersed, enhancing the compressive strength of the packaging carton 11, thereby preventing the packaging carton 11 from deforming and being damaged due to excessive pressure during the transfer process.

[0047] In this embodiment: Through the design of driving the support block 43 to slide out of the support rod 36 by the control rod 42, the contact area between the support rod 36 and the bottom of the packaging carton 11 is increased, which can effectively prevent the goods from being damaged due to shaking or extrusion during the transfer process, ensuring the safe transfer of the goods. Furthermore, the support for the bottom of the packaging carton 11 is improved, increasing the compressive strength of the packaging carton 11, and preventing the packaging carton 11 from deforming and being damaged due to excessive pressure during the transfer process.

[0048] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0049] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
