Description

Technical Field

[0001] This utility model relates to the field of charcoal rod production technology, specifically to a charcoal rod wax-impregnation conveying device. Background Technology

[0002] The wax impregnation tank is heated electrically or with heat transfer oil to keep the wax in a liquid state. Manual operation involves operators placing charcoal rods into a basket, immersing them in the wax tank, keeping them submerged for a period, then removing them, draining them, and placing them in a cooling area or on a conveyor belt. Impregnation time is controlled by worker experience and is uneven. Impregnation depth is difficult to control precisely, potentially resulting in some areas not being impregnated or wasting paraffin wax. Direct exposure to high-temperature molten wax and fumes poses a risk of burns and fires.

[0003] Currently, medium and large-sized manufacturers use fully automated conveying devices to form a continuous closed-loop production line of "feeding-waxing-draining". Chinese patent CN219024871U discloses a wax-impregnation hook device, including a hook and a conveying mechanism. The hook is connected to the conveying mechanism and moves along it. One end of the conveying mechanism is connected to a feeding chamber for suspending materials on the hook. The middle of the conveying mechanism is connected to a preheating chamber for preheating the materials suspended on the hook. The other end of the conveying mechanism is connected to a wax-impregnation tank for impregnating the materials suspended on the hook. The upper part of the wax-impregnation tank is equipped with a cover that encloses the upper opening of the tank, and the cover has an exhaust device for discharging water vapor from above the tank. However, the existing technology still requires manual removal of the hanging frame, resulting in low efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome the shortcomings and defects mentioned in the background art above, and to provide a highly automated, efficient, and safe carbon rod wax-impregnation conveying device. To solve the above technical problem, the technical solution proposed by this utility model is as follows: A carbon rod wax-impregnation conveying device includes: a truss robot assembly, comprising a first truss robot with a wax-impregnation inlet, a second truss robot positioned between wax-impregnation tanks, and a third truss robot with a wax-impregnation outlet. The first and second truss robots each include multiple columns and X-axis, Y-axis, and Z-axis tracks and servo motors fixed to the top of the columns. The third truss robot includes multiple columns and X-axis, Z-axis tracks and servo motors fixed to the top of the columns. A hook is fixed on the Z-axis track. A rotating shaft and a rotating shaft servo motor are provided on the Z-axis tracks of the second and third truss robots. The overhead chain conveyor assembly includes multiple overhead chain conveyors connected between multiple gantry robots. Each overhead chain conveyor is equipped with multiple roller groups and a conveyor chain mounted on the roller groups. The mounting frame of each roller group is equipped with a hook for suspending a material frame.

[0005] In one embodiment, the bottom of the column is provided with a leveling mechanism.

[0006] In one embodiment, the mounting bracket is an I-beam.

[0007] In one embodiment, an automatic unloading device is also included, which is located on one side of the third gantry robot. The automatic unloading device includes a scissor lift platform, a clamping assembly, and a tilting motor. After the third gantry robot places the material frame on the scissor lift platform, the clamping assembly clamps the material frame tightly. After the tilting motor drives the clamping assembly to rotate and unload the material frame, the clamping assembly releases the material frame and places it on the scissor lift platform. The scissor lift platform descends to be level with the ground and removes the empty material frame.

[0008] In one embodiment, two or more sets of the truss robot group and the overhead conveyor line group are provided respectively.

[0009] In one embodiment, the roller assembly is provided with multiple hooks.

[0010] In one embodiment, each roller assembly includes two rollers arranged symmetrically.

[0011] In one embodiment, the clamping assembly includes a first clamp and a second clamp arranged symmetrically, the first clamp and the second clamp forming a circle, the first clamp and the second clamp clamping the material frame when they are close to each other, and releasing the material frame when they are far apart from each other.

[0012] In one embodiment, the hook includes two symmetrically arranged claws, the top of the material frame is fixed to a connecting rod and a locking plate is fixed to the connecting rod, and when the material frame is suspended on the hook, it is engaged with the two claws by the locking plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the above-mentioned carbon rod wax-impregnation conveying device, the first gantry robot at the wax-impregnation inlet picks up the material frame loaded with unimpregnated carbon rods from the initial position and places it on the subsequent conveyor line or workstation. Driven by a servo motor, it can move along the X / Y / Z axes to ensure accurate positioning. The second gantry robot is set between the wax-impregnation tanks and is responsible for immersing the material frame into the wax tank and lifting it after wax impregnation. The Z-axis of the second gantry robot is equipped with a rotating shaft and a servo motor: it can perform controllable rotation when lifting the material frame, thereby shaking off or dislodging excess wax liquid, ensuring a uniform wax layer on the carbon rods and avoiding wax nodules. The third gantry robot at the wax-impregnation outlet is responsible for removing the material frame that has completed wax impregnation and dripping wax from the production line and entering the next stage. The overhead chain conveyor line connects the various gantry robots and is responsible for horizontally conveying the material frames between workstations, forming a continuous logistics line to achieve high automation and high-efficiency conveying.

Detailed Implementation

[0023] To facilitate understanding of this utility model, the following description will be provided in more comprehensive and detailed manner with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0024] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of protection of this invention.

[0025] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this invention can be purchased from the market or prepared by existing methods.

[0026] Please see Figure 1-7 One embodiment of the carbon rod wax-impregnation conveying device includes: a truss robot assembly, comprising a first truss robot 10 with a wax-impregnation inlet, a second truss robot 20 disposed between wax-impregnation tanks, and a third truss robot 30 disposed at a wax-impregnation outlet. The first truss robot 10 and the second truss robot 20 each include multiple columns 11 and X-axis rails 12, Y-axis rails 13, and Z-axis rails 14 fixed to the top of the columns 11, and a servo motor. The third truss robot 30 includes multiple columns 11 and rails fixed to the top of the columns 11. The system includes an X-axis track 12, a Z-axis track 14, and a servo motor. A hook 18 is fixed on the Z-axis track 14. The second gantry robot 20 and the third gantry robot 30 are equipped with a rotating shaft 21 and a rotating shaft servo motor 22 on the Z-axis track 14. The servo motors include a Y-axis servo motor 15 and a Z-axis servo motor 16. The material frame is hung on the hook 18. The Z-axis servo motor 16 drives the hook to move up and down along the Z-axis. The Z-axis track 14 is movably set on the Y-axis track. The Y-axis servo motor 15 drives the Z-axis track 14 to move along the X-axis.

[0027] The overhead chain conveyor line 40 includes multiple overhead chain conveyors connected between multiple gantry robots. Each overhead chain conveyor line is provided with multiple roller sets 42 and conveyor chains 44 set on the roller sets 42. The mounting brackets 442 of the roller sets 42 are provided with hooks 443. The hooks 18 and 443 are used to suspend the material frame.

[0028] In one embodiment, preferably, the roller assembly 42 is provided with multiple hooks 443. This allows for the wax impregnation of multiple material frames to be completed at once, improving efficiency.

[0029] In one embodiment, each roller assembly 42 includes symmetrically arranged double rollers 441. The symmetrically arranged double rollers 441 form a stable support point, which can effectively prevent the conveyor chain 44 from shaking, tilting or derailing during operation, and ensure the smoothness and reliability of the material frame conveying process.

[0030] In one embodiment, a leveling mechanism 17 is provided at the bottom of the column 11. The leveling mechanism 17 can quickly and accurately adjust the height of each column 11 on site to ensure that all tracks are at the same horizontal reference, thereby avoiding jamming, shaking or positioning deviation of the robot arm during operation.

[0031] In one embodiment, preferably, the mounting bracket 442 is an I-beam. The cross-sectional shape of the I-beam gives it extremely high strength and rigidity when subjected to vertically downward loads, making it suitable for suspending heavy material frames and carbon rods.

[0032] In one embodiment, an automatic unloading device 50 is also included, located on one side of the third gantry robot 30. The automatic unloading device 50 includes a scissor lift platform, a clamping assembly 52, and a tilting motor 54. After the third gantry robot 30 places the material frame onto the scissor lift platform, the clamping assembly 52 grips the frame tightly. The tilting motor 54 drives the clamping assembly 52 to rotate and unload the material. After unloading, the clamping assembly 52 releases the frame and places it back onto the scissor lift platform. The scissor lift platform then lowers to ground level, removing the empty frame. The automatic unloading device 50 solves the problem of automatic unloading of materials after waxing, making the entire process from loading, waxing, to collection completely free of manual intervention. It replaces the dangerous manual handling and tilting of heavy frames, avoiding workplace injuries. The scissor lift platform lowers the empty frame to ground level, making it easy for workers or AGVs to remove without bending or lifting, a very user-friendly design.

[0033] In one embodiment, preferably, the clamping assembly 52 includes a first clamp and a second clamp symmetrically arranged, forming a circle. When the first and second clamps are close together, they clamp the material frame; when they are far apart, they release the material frame. The circular clamp design perfectly encloses the cylindrical material frame (or a similar shape), and the applied clamping force is evenly distributed, avoiding localized stress concentration that could lead to deformation or damage to the material frame. The opening and closing actions of the first and second clamps are driven by a pneumatic or hydraulic cylinder, resulting in a simple structure, convenient control, and a low failure rate.

[0034] In one embodiment, two or more sets of the gantry robot assembly and the overhead conveyor line 40 are respectively installed. This allows for a significant increase in production capacity to meet the demands of a expanding market. Even if one system malfunctions and requires maintenance, the other system can continue production, reducing the risk of a complete production stoppage.

[0035] In the aforementioned carbon rod wax-impregnation conveying device, the first gantry robot 10 at the wax-impregnation inlet picks up the material frame loaded with unimpregnated carbon rods from its initial position and places it on the subsequent conveyor line or workstation. Driven by a servo motor, it can move along the X / Y / Z axes, ensuring precise positioning. The second gantry robot 20 is positioned between the wax-impregnation tanks, responsible for immersing the material frame in the wax tank and lifting it after impregnation. The Z-axis of the second gantry robot 20 is equipped with a rotating shaft 21 and a servo motor: it can perform controlled rotation when lifting the material frame, thereby shaking off or dislodging excess wax, ensuring a uniform wax layer on the carbon rods and preventing wax nodules. The third gantry robot 30 at the wax-impregnation outlet is responsible for removing the material frame that has completed wax impregnation and dripping from the production line for the next stage. The overhead conveyor line 40 connects the various gantry robots, responsible for horizontally conveying the material frames between workstations, forming a continuous logistics line that achieves high automation and high-efficiency conveying.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
