Description

Technical Field

[0001] This utility model belongs to the technical field of platinum alloy catalytic mesh production weaving equipment, and particularly relates to a weaving machine for producing platinum alloy catalytic mesh. Background Technology

[0002] The types of raw materials that can be used with braiding machines include: nylon multifilament, polypropylene filament, polypropylene, polyester, nylon, PP, low elasticity, high elasticity, cotton yarn, pearl yarn, leather, and blends. However, the production process of platinum alloy catalytic mesh requires the use of corresponding braiding equipment.

[0003] The existing platinum alloy catalytic mesh is a single-layer alloy mesh woven using flat looms, warp knitting machines, and weft knitting machines. When in use, it is cut to a suitable size according to the size of the customer's oxidation furnace. Multiple layers of single or multiple grades of alloy mesh are stacked together and installed in the oxidation furnace to meet the customer's catalytic oxidation needs, depending on the customer's process.

[0004] This innovative equipment tucks platinum alloy wires onto a plain-woven platinum alloy mesh using tufting needles, thereby producing platinum alloy catalytic mesh. Traditional tufting needles often have a fixed and inconveniently adjustable spacing, limiting production to products with the same tufting density. This not only affects the applicability of the equipment but also results in low functionality and poor performance. Therefore, a weaving machine for producing platinum alloy catalytic mesh is urgently needed to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a weaving machine for producing platinum alloy catalyst mesh, in order to solve the problem mentioned in the background art that, during the production process, the spacing between the tufting needles is mostly fixed and not easy to adjust, which means that it can only produce products with the same tufting density, which not only affects the applicability of the device, but also leads to low functionality and poor performance of the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A weaving machine for producing platinum alloy catalytic mesh includes a tufting machine body, a tufting assembly mounted on the upper end of the tufting machine body, and a tufting density adjustment component disposed inside the needle plate of the tufting assembly. The tufting density adjustment component includes:

[0008] An adjustment cavity is arrayed inside the needle plate to provide installation space for the adjustment mechanism;

[0009] The adjustment motor is fixed at the top of the adjustment cavity as a power source.

[0010] The screw, fixed on the output shaft of the regulating motor and cooperating with the screw block, can drive the tufting needles to move up and down;

[0011] A partition plate, fixed in the middle of the adjustment cavity and connected to the bottom end of the screw, can support the bottom end of the screw and ensure its stability during rotation;

[0012] A linkage rod is symmetrically fixed to the bottom end of the screw block and passes through the partition plate;

[0013] The support block, fixed to the bottom end of the linkage rod, is used to provide an installation position for the tufting needle.

[0014] By adopting the above technical solution, when platinum alloy wire is tufted onto a flat weave mesh, the corresponding adjusting motor can be controlled according to the tuft density to drive the screw to rotate. In turn, the screw block, under the action of the thread, drives the tuft needle to move upward through the linkage rod and hide it in the adjusting cavity. This allows the tuft density to be adjusted, ensuring the applicability and effectiveness of the device.

[0015] Furthermore, the tufted assembly includes:

[0016] The bracket is fixed to the upper end of the tufting machine body;

[0017] An electric push rod is symmetrically installed on the bottom end of the top wall of the bracket, and its movable part is connected to the needle plate.

[0018] By adopting the above technical solution, the electric push rod drives the tufting needle to move up and down reciprocally through the needle plate, thereby tufting the platinum alloy wire onto the surface of the flat woven mesh, thus forming a tufted alloy blanket. Compared with traditional knitted mesh and flat woven mesh, the tufted alloy blanket can adjust the tufting height according to the reaction pressure of the customer's device, and can indirectly adjust the residence time of the process gas, and more accurately adjust the catalyst loading amount.

[0019] Furthermore, the tufted assembly also includes:

[0020] Guide grooves are symmetrically provided on the side wall of the bracket to guide the movement of the needle plate;

[0021] The guide block is slidably disposed in the guide groove and symmetrically fixed on both sides of the needle plate to ensure the stability of the needle plate when it is raised and lowered.

[0022] By adopting the above technical solution, the guide groove and the guide block can be combined to guide the movement of the needle plate, thereby ensuring its stability during lifting and lowering.

[0023] Furthermore, the tufted assembly also includes:

[0024] The wire guide plate is set on the back wall of the needle plate and has multiple sets of wire grooves arrayed at its upper end. It can guide the platinum alloy wires while organizing them, preventing them from getting tangled together.

[0025] By adopting the above technical solution, during the tufting process, the wire groove on the wire board can separate and guide the platinum alloy wire, thereby ensuring the smooth and orderly transport of the platinum alloy wire.

[0026] Furthermore, a bearing assembly is also provided on one side of the upper end of the tufting machine body. The bearing assembly includes a symmetrically fixed bearing frame and a feeding roller disposed within the bearing frame.

[0027] By adopting the above technical solution, the wire release roller can release the platinum alloy wire.

[0028] Furthermore, a conveying assembly is fixed on the other side of the upper end of the tufting machine body. The conveying assembly includes symmetrically fixed supports and conveying rollers disposed between the supports. A conveying motor is fixed on one side wall of the support, and the output shaft of the conveying motor is fixedly connected to one end of the conveying rollers.

[0029] By adopting the above technical solution, during the tufting process, the conveying motor drives the conveying roller to rotate, and the conveying roller moves the tufted alloy blanket by friction, thereby conveying it.

[0030] Furthermore, an operation panel is installed on one side wall of the tufting machine body, and the operation panel has a built-in display screen and control module.

[0031] By adopting the above technical solution, the operation panel control device is activated.

[0032] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows:

[0033] This invention utilizes a tufting density adjustment assembly consisting of an adjusting motor, a screw, a screw block, and a linkage rod. The adjusting motor is controlled according to the tufting density, causing it to drive the screw to rotate. The screw block, acting on the thread, adjusts the tufting density by regulating the gap between the tufting needles, thus improving the applicability and effectiveness of the device.

[0041] To make the objectives, technical solutions, and advantages 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.

[0042] like Figure 1 , Figures 3-5 As shown, a weaving machine for producing platinum alloy catalytic mesh includes a tufting machine body 1, a tufting assembly 3 mounted on the upper end of the tufting machine body 1, and a tufting density adjustment assembly 6 disposed inside the needle plate 303 within the tufting assembly 3. The tufting density adjustment assembly 6 includes: an adjustment cavity 601 arrayed inside the needle plate 303 to provide installation space for the adjustment mechanism; an adjustment motor 602 fixed at the top of the adjustment cavity 601 as a power source; a screw 603 fixed on the output shaft of the adjustment motor 602 and cooperating with a screw block 605 to drive the tufting needles 304 to rise and fall; a partition 604 fixed in the middle of the adjustment cavity 601 and connected to the bottom end of the screw 603 to support the bottom end of the screw 603 and ensure its stability during rotation; a linkage rod 606 symmetrically fixed at the bottom end of the screw block 605 and penetrating through the partition 604; and a bearing block 607 fixed at the bottom end of the linkage rod 606 to provide installation positions for the tufting needles 304.

[0043] The specific steps are as follows:

[0044] When tufting platinum alloy wire onto a flat weave mesh, the corresponding adjusting motor 602 can be controlled according to the tufting density to drive the screw 603 to rotate. This causes the screw block 605 to move the tufting needle 304 upward through the linkage rod 606 under the action of the thread, hiding it in the adjusting cavity 601. The tufting density can then be adjusted by adjusting the gap between the tufting needles, ensuring the applicability and effectiveness of the device.

[0045] like Figures 1-4 As shown, in one embodiment, the tufting assembly 3 includes: a bracket 301, fixed to the upper end of the tufting machine body 1; an electric push rod 302, symmetrically installed on the top and bottom ends of the bracket 301, with its movable part connected to the needle plate 303; a guide groove 305, symmetrically opened on the side wall of the bracket 301, for guiding the movement of the needle plate 303; a guide block 306, slidably disposed in the guide groove 305 and symmetrically fixed on both sides of the needle plate 303, to ensure the stability of the needle plate 303 when it rises and falls; and a wire guide block 307, disposed on the back wall of the needle plate 303, with multiple sets of wire guide grooves 308 arrayed at its upper end, which can guide the platinum alloy wires while organizing them, preventing them from tangling together.

[0046] The specific steps are as follows:

[0047] During the tufting process, platinum alloy wires are passed through the guide groove 308 and the needle holes on the tufting needles 304. Then, the electric push rod 302 drives the tufting needles 304 to move up and down reciprocally through the needle plate 303. During the movement, the guide block and the guide groove 305 combine to limit and guide the movement, ensuring its stability. The platinum alloy wires are then tufted onto the surface of the flat woven mesh, forming a tufted alloy blanket. At the same time, the guide groove 308 on the guide block 307 can separate and guide the platinum alloy wires, ensuring the smooth and orderly transport of the platinum alloy wires. Compared with traditional knitted mesh and flat mesh, the tufted alloy blanket can adjust the tufting height according to the reaction pressure of the customer's equipment, which can indirectly adjust the residence time of the process gas and more accurately adjust the catalyst loading.

[0048] like Figure 1 As shown, in one embodiment: a bearing component 2 is also provided on one side of the upper end of the tufting machine body 1. The bearing component 2 includes a symmetrically fixed bearing frame 201 and a feeding roller 202 disposed in the bearing frame 201. A conveying component 4 is fixed on the other side of the upper end of the tufting machine body 1. The conveying component 4 includes a symmetrically fixed support 401 and a conveying roller 402 disposed between the supports 401. A conveying motor 403 is fixed on one side wall of the support 401. The output shaft of the conveying motor 403 is fixedly connected to one end of the conveying roller 402. An operation panel 5 is installed on one side wall of the tufting machine body 1. The operation panel 5 has a built-in display screen and a control module.

[0049] The specific steps are as follows:

[0050] The device operates via the control panel 5. The pay-off roller 202 releases the platinum alloy wire, and the conveyor motor 403 drives the conveyor roller 402 to rotate. The conveyor roller 402 moves the tufted alloy blanket by friction, thereby conveying it.

[0051] In summary, the working principle of this weaving machine for producing platinum alloy catalytic mesh is as follows: First, the device is placed in position and connected to an external power source. Then, a flat-woven mesh with a small mesh count and few holes is fed onto the tufting machine body 1. Next, the corresponding adjusting motor 602 is controlled via the operation panel 5 to drive the screw 603 to rotate. This causes the screw block 605 to move the tufting needles 304 upwards via the linkage rod 606 under the action of the screw thread, hiding them inside the adjusting cavity 601. The tufting density can then be adjusted by regulating the gap between the tufting needles 304. After adjustment, the platinum alloy wire is passed through the guide wire groove 308 and the needle holes on the tufting needles 304. Finally, the electric push rod 302 drives the tufting needles 304 through the needle plate 303. The wires move up and down repeatedly. During this movement, the wire block and guide groove 305 combine to limit and guide them, ensuring the stability of the movement. This tufts the platinum alloy wires onto the surface of the flat woven mesh, forming a tufted alloy blanket. During the tufting process, the wire groove 308 on the wire block 307 can separate and guide the platinum alloy wires, ensuring the smooth and orderly transport of the platinum alloy wires. The conveying motor 403 drives the conveying roller 402 to rotate. The conveying roller 402 moves the tufted alloy blanket by friction, thus transporting it. Compared with traditional knitted and flat woven meshes, the tufted alloy blanket can adjust the tufting height according to the reaction pressure of the customer's equipment, which can indirectly adjust the residence time of the process gas and more accurately adjust the catalyst loading amount.

[0052] The above are merely preferred embodiments of the present utility model and are 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.
