Description

Technical Field

[0001] This utility model relates to the field of box-turning machine technology, and in particular to a mobile box-turning machine. Background Technology

[0002] In tobacco processing, the blending process is a key step in cigarette manufacturing, and its blending uniformity and proportioning accuracy have a decisive impact on the intrinsic quality and style stability of cigarette products.

[0003] In actual production, the uniformity and stability of blending are mainly measured by the blending precision, and improving the blending precision is a key measure to ensure the intrinsic quality of cigarette products.

[0004] Furthermore, it is worth noting that in resource-saving production practices, automated unpacking lines typically handle the automatic feeding of large batches of tobacco leaves (the majority of the finished tobacco product), while smaller batches (the minority of the finished tobacco product) rely on manual handling for dumping and blending. Given the high position of the mixing mechanism's feed inlet, the corresponding conveyor belt is also designed to be at a relatively high height.

[0005] In current technology and equipment, the mixing operation requires two people to work together. However, due to the high position of the conveyor belt and its continuous operation, manual feeding poses significant safety hazards.

[0006] Based on this, this study believes it is necessary to develop a mobile box-turning machine that can reduce operational risks, achieve automation, and enable small-batch feeding to save energy. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention proposes a mobile box-turning machine. This equipment features small-batch material lifting capabilities and automatic material dumping, effectively overcoming the limitations of existing devices that rely heavily on manual feeding when handling small batches. This significantly reduces operating time and labor intensity, and minimizes operational risks. For example, in the field of tile packaging, the box-feeding-turning machine proposed in this invention automates the packaging process through the coordinated operation of conveying, turning, box-grabbing, and box-feeding mechanisms, reducing manual intervention. Furthermore, the ingenious design of the double-hydraulic container turner improves loading and unloading efficiency and safety, providing a more user-friendly working environment for logistics industry workers.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A mobile box-turning machine includes two conveying mechanisms arranged in a front-to-back configuration, with their conveying directions perpendicular. The upper surface of the rear conveying mechanism is higher than that of the front conveying mechanism. A lifting mechanism is provided between the two conveying mechanisms. The lifting mechanism includes two symmetrically arranged support frames. Each support frame has a vertical drive component on its inner side, and a synchronization component is provided between the two vertical drive components. A follower is provided near the end of each support frame, and the follower moves vertically relative to the support frame via the vertical drive component. A cargo basket is provided between the two follower components. A driven roller is fixedly connected to the upper end of the cargo basket, and the two axial ends of the driven roller are rotatably connected to the two follower components. A positioning plate is fixedly connected to the two axial ends of the driven roller, and the positioning plate is located behind the driven roller. A limiting plate I is fixedly connected to the far end of each support frame, and the limiting plate I and the positioning plate are in the same vertical plane.

[0010] Preferably, the conveying mechanism located on the front side is a roller conveyor, and the conveying mechanism located on the rear side is a belt conveyor. Furthermore, the conveying mechanism located on the front side includes a bearing base, and a plurality of left and right axial support rollers are fixedly connected to the upper end face of the bearing base.

[0011] Preferably, the basket includes a connecting plate, and a plurality of rectangular frames are fixedly connected to the front side of the connecting plate. The plurality of rectangular frames are arranged at equal intervals from front to back, and when the basket is at its lowest point of travel, the basket is embedded between a plurality of support rollers.

[0012] Preferably, the inner side of the basket is provided with two clamps, which are arranged left and right. A cylinder is provided at the rear end of the two clamps. The connecting plate has a sliding groove for the clamps, and the clamps are inserted into the sliding groove. The fixed end of the cylinder is fixedly connected to the rear end face of the connecting plate, and the movable end of the cylinder is fixedly connected to the corresponding clamp.

[0013] Preferably, each follower is fixedly connected to a limiting plate II on its rear side. The limiting plate II is located in front of the limiting plate I, and the limiting plate II and the positioning plate are in the same vertical plane. When the positioning plate abuts against the limiting plate II, the lower end face of the basket is parallel to the horizontal plane.

[0014] Preferably, the two support frames are provided with multiple through holes I at their far ends, and the multiple through holes I are arranged in a rectangular array. Furthermore, the limiting plate I is provided with through holes II for the through holes I, and a fixing bolt is inserted into both the through holes I and the corresponding through holes II.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention designs a device that uses upper and lower driving components to drive a driven roller. This device enables the transfer of basket height, thereby effectively transferring materials. Furthermore, through the cooperation of a positioning plate and a limiting plate I, the device ensures that the basket automatically rotates when it reaches a predetermined position during upward movement, thus emptying the loose materials inside the basket. This design not only reduces the use of driving components but also achieves the technical effect of reducing energy consumption. Attached Figure Description

[0023] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings to ensure that the technical solution is clearly and completely described. It should be noted that the mentioned embodiments are merely examples and do not represent the entire scope of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, terms such as "upper" and "lower" are based on the accompanying drawings and are intended to simplify the description and facilitate understanding. These terms do not limit the actual location or structure of the device or component and should therefore not be considered as constraints on this utility model.

[0025] Please refer to Figure 1 A mobile box-turning machine, whose design is consistent with existing technology devices, has two conveying mechanisms 1 arranged in a front-to-back manner.

[0026] In the application scenarios of this device, the two conveying mechanisms 1 are typically perpendicular in their conveying directions, and the upper surface of the rear conveying mechanism 1 is higher than that of the front conveying mechanism 1. This design aims to realize the transfer of materials between different heights, and during the transfer process, this device can perform the functions of flipping the cargo box and tipping the materials.

[0027] Therefore, it is worth noting that, in order to ensure that loose materials can be properly transferred, the conveying mechanism 1 located at the rear adopts a belt conveyor. The belt conveyor uses a conveyor belt to ensure that no loose materials are missed during the conveying process.

[0028] Furthermore, the conveying mechanism 1 located at the front is typically a roller conveyor. The special structural design of the roller conveyor can both support the cargo box and effectively avoid conflicts with the actual operating equipment during material transfer, thereby improving the applicability of the device.

[0029] See Figure 1 Specifically, the conveying mechanism 1 located at the front includes a support base 4, and multiple left and right axial support rollers 3 are fixedly connected to the upper end of the support base 4.

[0030] Please see Figure 1 , Figure 2 Unlike existing technology devices, this device has a lifting mechanism 2 between the two conveying mechanisms 1.

[0031] Please see Figure 2 , Figure 3 The lifting mechanism 2 includes two support frames 201 arranged symmetrically on the left and right.

[0032] On the inner side of each of the two support frames 201, there is a vertical drive component 203. For example... Figure 3 As shown, in this device, the up and down driving component 203 includes a lead screw and a matching limiting rod, which is a prior art device and will not be described in detail here.

[0033] Meanwhile, a follower 10 is installed near the proximal ends of each of the two support frames 201. For example... Figure 3 As shown, the follower 10 has an internal threaded hole for the lead screw, and a corresponding limiting hole for the limiting rod. The limiting rod restricts the rotation of the follower 10, ensuring that it can only move up and down along the lead screw. When the drive motor drives the lead screw to rotate, the follower 10 rises and falls accordingly.

[0034] It is worth noting that the cargo basket 7 used to lift the cargo box is set between the two follower members 10, and the cargo basket 7 and the follower members 10 are synchronized in height.

[0035] To avoid stroke conflicts, a synchronization mechanism is provided between the two upper and lower drive components 203 to ensure that they can coordinate and drive the follower 10 to perform linear lifting and lowering. Figure 3 As shown, the synchronizing component 202 consists of a chain and a sprocket. The chain and sprocket are meshed and connected, while the sprocket is connected to two lead screws. This utilizes the transmission effect of the chain to ensure that the lead screws in the two upper and lower driving components 203 always rotate synchronously.

[0036] like Figure 2 , Figure 4 As shown, in order to achieve synchronous lifting of the basket 7 and the follower 10, the device fixes a driven roller 6 at the upper end of the basket 7, and its two ends are respectively connected to the two follower 10.

[0037] Please see Figure 2 , Figure 3 , Figure 4 In order to enable the device to flip the cargo box and dump the materials during the transfer process, the two axial ends of the driven roller 6 are respectively rotatably connected to two follower components 10.

[0038] Specifically, in order to achieve material transfer between different heights, and to simultaneously perform the technical functions of flipping the cargo box and dumping materials during the transfer process, this device has a positioning plate 11 fixedly connected to each of the two axial ends of the driven roller 6, with the positioning plate 11 located on the rear side of the driven roller 6.

[0039] Meanwhile, a limiting plate I5 is fixedly connected to the far end of each of the two support frames 201. By constraining the limiting plate I5 and the positioning plate 11 to be in the same vertical plane, the uneven force on the front and rear sides of the basket 7 can be used to achieve the flipping of the basket 7 and achieve the technical effect of dumping materials.

[0040] In actual operation, the driven roller 6 continuously drives the basket 7 to rise along with the follower 10. The positioning plate 11 rises accordingly and abuts against the limit plate I5. The driven roller 6 rotates through the change in height, thereby causing the basket 7 to rotate with the driven roller 6, achieving the effect of tilting the material.

[0041] Furthermore, in practice, the greater the height difference between the positioning plate 11 and the driven roller 6, the greater the rotation angle of the driven roller 6. This allows the device to determine the rotation angle of the driven roller 6 by the running time of the upper and lower drive components 203, thereby adjusting the speed of material pouring.

[0042] It is worth noting that, in practice, the height of the limiting plate I5 determines the height at which the device pours material. By adjusting the position of the limiting plate I5, this device can flexibly adapt to materials of different sizes, ensuring that the position of the poured material is precisely aligned with the bearing surface of the rear conveying mechanism 1, thereby improving the accuracy and efficiency of material conveying.

[0043] Therefore, this device has multiple through holes I9 at the far ends of the two support frames 201, and these through holes I9 are arranged in a rectangular array. In addition, the limiting plate I5 has a corresponding through hole II for each through hole I9, and a fixing bolt 8 is inserted into both, thereby realizing a detachable fixed connection between the limiting plate I5 and the support frame 201, and thus the height of the limiting plate I5 can be flexibly adjusted as needed.

[0044] Additionally, it should be noted that in practical applications, the basket 7 is usually positioned in front of the driven roller 6. This is mainly to match the front conveying mechanism 1 and ensure that the cargo box can be smoothly transferred into the basket 7.

[0045] Therefore, to prevent the basket 7 from tipping over due to its own weight causing an imbalance in the forces on the front and rear sides of the driven roller 6 during the upward movement of the driven roller 6 and the basket 7, and to prevent the basket 7 from losing its supporting function for the cargo box due to the height difference between the basket 7 and the driven roller 6, this device has a limiting plate II 12 fixedly connected to the rear side of each follower 10. The limiting plate II 12 and the positioning plate 11 are in the same vertical plane. Therefore, by further constraining the lower end surface of the basket 7 to be parallel to the horizontal plane when the positioning plate 11 abuts against the limiting plate II 12, the technical effect of the limiting plate II 12 constraining the positioning plate 11 is achieved, ensuring that the basket 7 can only flip backward and ensuring the supporting effect of the basket 7 for the cargo box.

[0046] Please see Figure 4 , Figure 5 To ensure that the basket 7 can continuously support the cargo box, the device constrains the basket 7 by including a connecting plate 702, the front end of which is fixedly connected to multiple rectangular frames 701.

[0047] Furthermore, this device ensures that these rectangular frames 701 are arranged at equal intervals from front to back. Also, the interval between adjacent rectangular frames 701 is greater than the interval between adjacent support rollers 3. This design allows the basket 7 to be embedded between multiple support rollers 3 when it is at its lowest point in its travel, thus ensuring that the cargo boxes transferred via the front conveyor mechanism 1 can be directly embedded into the basket 7, saving subsequent operational steps.

[0048] In addition, to prevent the cargo box from falling directly onto the rear conveyor mechanism 1 due to gravitational potential energy during the tipping process, we added two symmetrical clamping plates 15 to the inside of the cargo basket 7, which are slidably connected to the cargo basket 7. By adjusting the spacing of the clamping plates 15, the cargo box can be clamped and fixed to ensure its relative stability with the cargo basket 7.

[0049] Specifically, this device has a groove 14 on the connecting plate 702 for the clamping plate 15, and the clamping plate 15 can be inserted into the groove 14, thereby realizing the movable connection between the clamping plate 15 and the connecting plate 702.

[0050] Meanwhile, a cylinder 13 is configured at the rear end of the two clamping plates 15. The fixed end of the cylinder 13 is fixedly connected to the rear end of the connecting plate 702, and the movable end of the cylinder 13 is fixedly connected to the corresponding clamping plate 15. In this way, the cylinder 13 can provide power for the movement of the clamping plates 15, ensuring that the distance between the two clamping plates 15 can be adjusted as expected.

[0051] In practical applications of this utility model:

[0052] First, the operator drives the two follower parts 10 to descend synchronously through the upper and lower drive components 203. During this process, the basket 7 moves to its lowest point of travel, and the lower end of the basket 7 is embedded between the support rollers 3.

[0053] Next, the operator uses the transfer mechanism to precisely move the cargo box above the front conveyor mechanism 1 and carefully adjusts the position of the cargo box to ensure that it is firmly embedded in the cargo basket 7.

[0054] Subsequently, the operator activated cylinder 13, which then drove the two clamping plates 15 to move slowly toward each other until they applied sufficient clamping force to the cargo box, at which point the clamping plates 15 came to a steady stop.

[0055] Then, the operator continues to manipulate the up and down drive component 203 to drive the basket 7 to rise smoothly. During this time, the limit plate II 12 and the positioning plate 11 continue to abut. Subsequently, as the basket 7 continues to rise, the positioning plate 11 meets and triggers the limit plate I 5, and the basket 7 immediately flips backward, successfully completing the dumping of loose materials.

[0056] Finally, the operator pulls the cargo basket 7 to reset, and uses the up and down drive component 203 to drive the two follower components 10 to move down synchronously. During this process, the cylinder 13 is operated in the opposite direction to release the clamping effect between the clamping plate 15 and the cargo box.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
