Description

Technical Field

[0001] This utility model belongs to the technical field of metal wire mesh spraying equipment, and more specifically, it relates to a multi-axis feeding rack. Background Technology

[0002] Epoxy resin coating is a treatment method for metal wire mesh, which enhances its corrosion and rust resistance, while also improving its wear resistance and mechanical strength, thus extending its service life. This coating is typically performed on the production line. Specifically, after the wire mesh is unwound, it passes through a feeding rack and enters the coating process. In this process, epoxy resin powder is sprayed onto the wire mesh, which then enters a heating furnace to cure the epoxy resin powder.

[0003] In existing technologies, the feeding rack has the following drawbacks: Since the heating furnace can simultaneously process multiple wire meshes, the feeding rack cannot be height-adjusted according to the mesh spacing, making it unsuitable for different types and feed heights of metal wire mesh. Furthermore, because different specifications of wire mesh require independent support frames to accommodate parameters such as the height of the heating furnace inlet, interference is likely to occur. Additionally, the feeding rack causes the wire mesh to tilt at an angle between the feeding rack and the heating furnace inlet. If the angle is too large, the wire mesh will wrinkle and shift, affecting the coating effect and reducing the product yield. Utility Model Content

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Reference Figures 1 to 3 The multi-axis feeding rack provided by this utility model will now be described. The multi-axis feeding rack includes a support 1, a feeding rack 2, and an adjustment component 3.

[0021] The feeding rack 2 is slidably connected to the support 1. The adjustment component 3 is set on the support 1 and connected to the feeding rack 2; the adjustment component 3 is located below the feeding rack 2; the adjustment component 3 includes a drive component 31 and a lifting mechanism 32 set on the support 1; one end of the lifting mechanism 32 is connected to the support 1, and the other end is fixedly connected to the feeding rack 2; the drive component 31 is connected to the lifting mechanism 32 and is used to drive the lifting mechanism 32 to unfold or fold, so as to adjust the height of the feeding rack 2.

[0022] Adjustment component 3, acting as the height adjustment execution unit, is located below and directly connected to the feeding rack 2, allowing it to directly apply lifting driving force to the feeding rack 2. When the height of the feeding rack 2 needs adjustment, the drive component 31 on the support 1 is activated. The drive component 31 transmits power to the lifting mechanism 32, controlling the lifting mechanism 32 to complete the unfolding or folding action. When the lifting mechanism 32 unfolds, its two ends move away from each other, and its middle position gradually decreases, thereby driving the feeding rack 2 to descend. When the lifting mechanism 32 folds, its two ends move closer together, and its middle position gradually rises, thereby driving the feeding rack 2 to rise. Throughout the process, the feeding rack 2 maintains a sliding connection with the support 1, ensuring a stable lifting trajectory and preventing deviation.

[0023] On the one hand, the height of the unloading rack 2 can be flexibly adjusted according to the inlet height of different models of metal wire mesh spraying machines, so that the unloading rack 2 and the inlet of the spraying machine are kept at a suitable horizontal height. This avoids the metal substrate forming an excessive tilt angle in the conveying path, thereby reducing wrinkles and offset problems caused by uneven force on the substrate, ensuring the registration accuracy of subsequent spraying processes, and improving the product qualification rate. On the other hand, the adjustment component 3 is set below the unloading rack 2, which not only saves the horizontal space of the equipment, but also enables the unloading rack 2 to be raised and lowered stably through the direct drive of the lifting mechanism 32. This avoids the unloading rack 2 shaking during the adjustment process, ensuring the stability of the substrate unwinding process, and further adapting to the requirements of substrate conveying stability in metal wire mesh spraying production.

[0024] In one possible implementation, the lifting mechanism 32 includes a first lead screw 321, a folding arm, and a drive seat 324.

[0025] The first lead screw 321 is rotatably connected to the bracket 1; the first lead screw 321 is connected to the drive component 31; the drive component 31 is used to drive the first lead screw 321 to rotate; the first lead screw 321 is provided with two sections of threads in opposite directions. The two ends of the folding arm are respectively threaded to the two ends of the first lead screw 321; a folding joint is provided in the middle of the folding arm. The drive seat 324 is hinged to the folding joint and fixedly connected to the feeding rack 2.

[0026] When the drive component 31 drives the first lead screw 321 to rotate, the two reverse threads can drive the two ends of the folding arm to move synchronously towards or away from each other along the lead screw, thereby controlling the folding arm to stably unfold or fold around the folding joint. This ensures balanced force during the lifting and lowering process of the feeding rack 2, avoiding unilateral deviation, and also improves the accuracy of height adjustment through the synchronicity of the mechanical structure. At the same time, the drive seat 324, which is hinged to the folding joint, converts the movement of the folding arm into the vertical lifting and lowering power of the feeding rack 2, making the lifting trajectory of the feeding rack 2 more stable and allowing for more precise control of the height adjustment range when adapted to spraying machines with different feeding heights.

[0027] In one possible implementation, the folding arm includes a first folding member 322 and a second folding member 323.

[0028] One end of the first folding member 322 is threaded to the end of the first lead screw 321, and the other end is hinged to the drive seat 324. One end of the second folding member 323 is threaded to the end of the first lead screw 321, and the other end is hinged to the drive seat 324; the first folding member 322 and the second folding member 323 are symmetrically arranged about the drive seat 324.

[0029] When the first lead screw 321 rotates, driving the components at both ends to move, the symmetrically arranged first and second folding parts 323 can simultaneously unfold or fold along the same trajectory, avoiding structural deformation caused by excessive force on one side of the folding part. At the same time, it ensures that the drive seat 324 is subjected to stable force, thereby driving the feeding rack 2 to rise and fall stably along the vertical direction of the support 1, reducing the offset or shaking of the feeding rack 2 during height adjustment. This symmetrical structure can also improve the load-bearing capacity of the folding arm. Even if multiple rolls of metal substrate are placed on the feeding rack 2, the stability of the lifting process can be maintained, further adapting to the requirements of height adjustment accuracy and load-bearing stability of the feeding rack 2 in metal wire mesh spraying, and reducing the problem of substrate conveying deviation caused by the shaking of the feeding rack 2.

[0030] In one possible implementation, the drive component 31 is a motor, which is fixedly connected to the bracket 1, and the power output shaft of the motor is connected to the first lead screw 321.

[0031] In one possible implementation, the feeding rack 2 includes a mounting frame 21, a rubber roller 22, and a fine-tuning assembly 23.

[0032] Mounting bracket 21 is slidably connected to support 1 and can be raised and lowered vertically; adjusting component 3 is fixedly connected to mounting bracket 21. Rubber roller 22 is slidably connected to mounting bracket 21; rubber roller 22 is horizontally positioned and can be raised and lowered vertically. Fine-tuning component 23 is fixedly connected to mounting bracket 21; fine-tuning component 23 is used to fine-tune the height of rubber roller 22.

[0033] Mounting bracket 21 serves as the basic load-bearing structure, slidably connected to support 1 and raised / lowered as a whole via adjusting component 3, meeting the height adaptation requirements of different spraying machine inlets. The rubber roller 22 is slidably connected to mounting bracket 21 and its height can be finely adjusted via adjusting component 23. This solves the problem of potential deviations in the adhesion between the rubber roller 22 and the substrate after overall height adjustment, and allows for precise adjustment of the roller 22 height according to the thickness of the metal substrate. This ensures uniform pressure from the rubber roller 22 on the substrate, preventing deformation due to excessive pressure or displacement due to excessive looseness during substrate transport. Simultaneously, the fine-adjustment function can accommodate minor adjustments in substrate tension during spraying, providing more precise assurance for subsequent spraying and printing accuracy, further improving product qualification rate.

[0034] In one possible implementation, the mounting bracket 21 is provided with a liftable slider 221, and the rubber roller 22 is rotatably connected to the slider 221; the fine-tuning component 23 is connected to the slider 221 and is used to drive the slider 221 to rise and fall.

[0035] In one possible implementation, the fine-tuning component 23 includes a second lead screw 231, a drive shaft 232, and a transmission mechanism.

[0036] The second lead screw 231 is rotatably connected to the mounting bracket 21; the second lead screw 231 is vertically arranged and threadedly engaged with the slider 221. The drive shaft 232 is arranged parallel to the second lead screw 231. A transmission mechanism is arranged between the drive shaft 232 and the second lead screw 231; the transmission mechanism is used to transmit power from the drive shaft 232 to the second lead screw 231.

[0037] The vertically positioned second lead screw 231 is threaded into the slider 221, converting rotation into stable vertical lifting and lowering of the slider 221, ensuring no deviation during height adjustment of the rubber roller 22. Simultaneously, the drive shaft 232 and the second lead screw 231 transmit power through a transmission mechanism. This avoids the potential space constraints of directly driving the second lead screw 231 and optimizes the ease of adjustment through power transmission, allowing operators to more easily control the fine-tuning of the rubber roller 22's height, thus precisely adapting to the pressing requirements of metal substrates of different thicknesses.

[0038] In one possible implementation, a mounting block is slidably connected to the mounting bracket 21, the mounting block can be raised and lowered in the vertical direction, and the drive shaft 232 is rotatably connected to the mounting block.

[0039] In one possible implementation, the transmission mechanism includes a first driving gear 233, a second driving gear 234, a first driven gear 235, and a second driven gear 236.

[0040] A first driving gear 233 is fixedly connected to a drive shaft 232; a second driving gear 234 is fixedly connected to the drive shaft 232; the diameter of the second driving gear 234 is smaller than the diameter of the first driving gear 233. A first driven gear 235 is fixedly connected to a second lead screw 231; the first driven gear 235 is used to mesh with the second driving gear 234. A second driven gear 236 is fixedly connected to the second lead screw 231; the diameter of the second driven gear 236 is smaller than the diameter of the first driven gear 235; the second driven gear 236 is used to mesh with the first driving gear 233. The engagement of the first driving gear 233 with the second driven gear 236 or the engagement of the second driving gear 234 with the first driven gear 235 can be switched by adjusting the height of the drive shaft 232.

[0041] The first driving gear 233 and the second driving gear 234 on the drive shaft 232, and the first driven gear 235 and the second driven gear 236 on the second lead screw 231 form two meshing combinations. When the height of the drive shaft 232 is adjusted so that the first driving gear 233 meshes with the second driven gear 236, the transmission ratio design of the large gear driving the small gear allows for rapid adjustment of the height of the rubber roller 22, suitable for scenarios requiring significant correction of the height deviation of the rubber roller 22. When the second driving gear 234 meshes with the first driven gear 235, the transmission ratio of the small gear driving the large gear converts the rotation of the drive shaft 232 into slow and precise rotation of the second lead screw 231, achieving micro-precise adjustment of the height of the rubber roller 22. This adapts to the subtle requirements of different thickness metal substrates for holding force, or the precise calibration requirements of substrate tension during spraying.

[0042] This dual-precision switching requires no additional complex drive components and can be achieved simply by adjusting the height of the drive shaft 232. This simplifies the structure and allows for flexible selection of adjustment efficiency and precision according to actual production needs. It effectively avoids problems such as improper substrate holding due to excessive adjustment range or production efficiency being affected by slow adjustment, providing more comprehensive protection for the stability of metal wire mesh coating substrate delivery and overprinting accuracy.

[0043] In one possible implementation, a handwheel 237 is provided at the end of the drive shaft 232.

[0044] The beneficial effects of the multi-axis feeding rack provided by this utility model are as follows: Compared with the prior art, the multi-axis feeding rack of this utility model can achieve flexible adjustment of the height of the feeding rack 2 by driving the lifting mechanism 32 with the drive component 31, thereby accurately adapting to the feed inlet height of metal wire mesh spraying machines of different specifications. It effectively avoids the problem of wrinkles and displacement of metal substrates due to excessive path tilt angle during the conveying process, reduces the phenomenon of spraying pattern misalignment, improves the product qualification rate, and ensures the stability of metal substrate conveying. It provides a reliable foundation for the overprinting accuracy of subsequent spraying processes and solves the core technical problem that the existing feeding rack 2 cannot adjust its height.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
