A tensioning device suitable for metal conveyor mesh

Abstract

This utility model discloses a tensioning device for metal conveyor nets, relating to the field of fiber production equipment. The device features a tensioning bracket that, under the push-pull action of a cylinder and the guidance of a linear guide rail, can smoothly move forward or backward along the length of the lower longitudinal beam. This tensioning bracket, in turn, drives the tensioning roller to move forward or backward synchronously. Because the metal conveyor net is arranged in an S-shape, passing sequentially around the tensioning roller and the deflecting roller, the metal conveyor net can be easily and accurately tensioned as the tensioning roller moves, laying the foundation for the smooth conveying of fiber materials and ensuring the quality of the finished product and the reliability of equipment operation. When the slack of the metal conveyor net exceeds the cylinder's adjustment stroke, the tensioning position of the deflecting roller can be adjusted to further tighten the metal conveyor net, reducing the frequency of replacement, simplifying operation, and extending the service life of the metal conveyor net. This utility model also has the advantages of reasonable design, compact structure, easy installation, reliable use, and small space occupation.

Description

Technical Field

[0001] This utility model relates to the technical field of fiber production equipment, specifically a tensioning device suitable for metal conveyor networks, especially suitable for tensioning metal conveyor networks transporting viscose fiber, Lyocell fiber, vinylon staple fiber, and carbon fiber. Background Technology

[0002] In the chemical fiber industry, post-processing of viscose fiber, Lyocell fiber, and vinylon staple fiber is an important step before the finished fiber product. The refining machine is one of the important unit machines in fiber post-processing, mainly used to perform processes such as washing, desulfurization, bleaching, and oiling on the cut short fibers to give the fibers good whiteness and spinnability.

[0003] Pre-oxidation of carbon fiber felt is an important step in the processing of carbon fiber felt. The washing machine is one of the key units in carbon fiber felt pre-oxidation, mainly used to remove impurities from the surface of the raw carbon fiber felt and precipitates such as metal salts from the pre-oxidized felt through solvent cleaning.

[0004] Whether it's a refining mill used for fiber post-processing or a washing machine used for carbon fiber felt pre-oxidation, a metal conveyor mesh is needed to transport the fiber material and complete processes such as washing, bleaching, and oiling. Therefore, the metal conveyor mesh is a crucial component of both the refining and washing mills, and its tension directly affects the quality of the finished product and the reliability of the equipment. Currently, most existing technologies for tensioning metal conveyor meshes use a rocker arm system—the tensioning roller is connected to the frame via a fixed shaft and a rocker arm, and the tensioning roller tensions the metal conveyor mesh by rotating around the fixed shaft with the rocker arm. This tensioning structure suffers from technical problems such as cumbersome installation, inconvenient maintenance, and large space occupation.

[0005] Metal conveyor mesh is needed to transport fibrous materials to complete processes such as washing, bleaching, and oiling. Therefore, the metal conveyor mesh is a crucial component of the refining and washing machines, and its tension directly affects the quality of the finished product and the operational reliability of the equipment. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the existing technology by providing a tensioning device suitable for metal conveyor networks. This invention enables convenient and accurate tensioning of metal conveyor networks, laying the foundation for the smooth transport of fibrous materials and providing a prerequisite guarantee for finished product quality and equipment operational reliability. Furthermore, this invention has the advantages of reasonable design, compact structure, easy installation, convenient maintenance, reliable use, and small space occupation.

[0007] The objective of this utility model can be achieved through the following measures:

[0008] This utility model discloses a tensioning device for metal conveyor networks, comprising two U-shaped frames (providing the installation and support foundation for other components) symmetrically arranged left and right, each welded together by a front column, a rear column, and a lower longitudinal beam. A tensioning bracket is horizontally mounted on the lower longitudinal beam of the two U-shaped frames, with its left and right bottom ends connected to the top surface of the lower longitudinal beam via linear guide rails. The front ends of the left and right ends are connected to the inner surface of the corresponding front column via cylinders. (The pushing and pulling action of the cylinders, combined with the guiding action of the linear guide rails, controls the tensioning bracket along the length of the lower longitudinal beam.) The direction can be smoothly moved forward or backward; at the same time, after the translation is in place, the pressure of the cylinder can be adjusted to balance the horizontal component of the tension force required by the metal conveyor network, so that the tensioning bracket is in a balanced state in the horizontal direction, and the position of the tensioning bracket in the horizontal direction is fixed. The tensioning roller is horizontally installed on the tensioning bracket (during the translation of the tensioning bracket along the length of the lower longitudinal beam, the tensioning roller will move forward or backward synchronously, and since the metal conveyor network passes around the tensioning roller, the tension of the metal conveyor network can be achieved). The deflecting roller is horizontally installed on the bottom surface of the lower longitudinal beam (to change the metal conveying...). The conveyor network moves in an S-shape to accommodate different material transport directions, sequentially passing through tension rollers and deflector rollers. The deflector rollers are positioned between the tension rollers and the rear column (ensuring the metal conveyor network maintains an S-shape as it passes through the tension rollers and deflector rollers, further guaranteeing tension). Several sets of adjustment holes are provided on the bottom surface of the lower longitudinal beam for adjusting the tension position of the deflector rollers (when the slack of the metal conveyor network exceeds the cylinder's adjustment stroke, the tension position of the deflector rollers can be adjusted to further tighten the metal). The conveyor network reduces the frequency of metal conveyor network replacement, which not only simplifies operation but also extends the service life of the metal conveyor network. A limit stop is arranged in front of the turning roller (to limit the position of the turning roller and provide a mounting base for the tightening bolt). The limit stop is equipped with a tightening bolt for tightening the bearing seat of the turning roller (providing a reaction force in the horizontal direction - that is, a reaction force that balances the forward horizontal force exerted by the metal conveyor network on the turning roller, so that the turning roller is in a balanced state in the horizontal direction, which can effectively prevent the turning roller from moving back and forth in the horizontal direction).

[0009] In this invention, the cylinder is connected to the inner side of the column via a rod end spherical bearing, and the cylinder is connected to the tensioning bracket via a single elbow joint (for easy and quick connection).

[0010] In this utility model, the position and diameter of each set of adjustment mounting holes are consistent with the bolt holes on the bearing seat base plate supported at both ends of the turning roller (ensuring smooth alignment when adjusting the tension position of the turning roller).

[0011] The linear guide rail described in this utility model adopts a high-load-bearing self-lubricating ball linear guide rail (which can ensure that the tensioning bracket can move smoothly in a straight line under the push and pull action of the cylinder, and will not tilt during the straight line movement, thus improving the reliability of use; the linear guide rail adopts a high-load-bearing self-lubricating ball linear guide rail, which also has the advantage of convenient maintenance). The fixed part of the linear guide rail is installed on the top surface of the lower longitudinal beam, and the sliding part of the linear guide rail is installed on the bottom surface of the tensioning bracket.

[0012] The tension roller and the deflection roller described in this utility model are both coated rollers with a rubber layer on their surface (this can increase the friction between the roller surface and the metal transport net, effectively prevent the metal transport net from slipping, and ensure the smooth movement of the metal transport net and the smooth transport of fiber materials).

[0013] The width of the tension roller and the turning roller described in this utility model is greater than the width of the metal transport net (to reserve a certain working gap to avoid the metal transport net from colliding with the tension support and the bearing seat of the turning roller and causing friction).

[0014] The design principle of this utility model is as follows:

[0015] This invention features a tensioning bracket that, under the pushing and pulling action of a cylinder and the guiding action of a linear guide rail, can smoothly move forward or backward along the length of the lower longitudinal beam. The tensioning bracket, in turn, drives the tensioning roller to move forward or backward synchronously. Because the metal conveyor mesh is arranged in an S-shape, passing sequentially around the tensioning roller and the deflecting roller, the tensioning of the metal conveyor mesh can be conveniently and accurately achieved by moving the tensioning roller back and forth. This lays the foundation for the smooth conveying of fiber materials and provides a prerequisite guarantee for the quality of the finished product and the reliability of equipment operation. Furthermore, when the slack of the metal conveyor mesh exceeds the adjustment stroke of the cylinder, the tension of the metal conveyor mesh can be further tightened by adjusting the tensioning position of the deflecting roller—that is, by selecting the corresponding matching adjustment mounting hole to install the deflecting roller, the tensioning position of the deflecting roller can be adjusted. This reduces the frequency of metal conveyor mesh replacement, simplifies operation, and extends the service life of the metal conveyor mesh. Meanwhile, this utility model utilizes a compact tensioning bracket to easily and quickly change the tensioning position of the tensioning roller and the turning roller by translating and selecting the adjustment mounting holes. Compared with the traditional swing rod type tensioning device, which is cumbersome to install, inconvenient to maintain, and occupies a lot of space, this utility model also has the advantages of reasonable design, compact structure, easy installation, convenient maintenance, reliable use, and small space occupation.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] This invention enables convenient and accurate tensioning of metal conveyor nets, reducing the frequency of replacement and extending their service life. This lays the foundation for the smooth transport of fibrous materials and provides a prerequisite guarantee for the quality of finished products and the reliability of equipment operation. In addition, this invention has the advantages of reasonable design, compact structure, easy installation, convenient maintenance, reliable use, and small space occupation.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figure 1 , 2As shown, a tensioning device for metal conveyor nets according to this utility model includes two U-shaped frames 11 (providing the installation and support foundation for other components in this utility model) that are welded together by a front column 1, a rear column 1', and a lower longitudinal beam 3, and are arranged symmetrically on the left and right sides. A tensioning bracket 5 is horizontally mounted on the lower longitudinal beam 3 of the two U-shaped frames 11, with its left and right bottom ends connected to the top surface of the lower longitudinal beam 3 via linear guide rails 4. The front ends of the left and right ends are connected to the inner side of the corresponding front column 1 via cylinders 2. (The pushing and pulling action of the cylinders 2, combined with the guiding action of the linear guide rails 4, can control the tensioning bracket 5 along the lower longitudinal beam 3.) The beam moves smoothly forward or backward along its length; simultaneously, after translating into position, the pressure of cylinder 2 can be adjusted to balance the horizontal component of the tension required for the metal conveyor network 8, ensuring the tensioning bracket 5 is in a balanced state in the horizontal direction and thus fixing its position. The tensioning roller 6, horizontally mounted on the tensioning bracket 5, moves forward or backward synchronously during the translation of the tensioning bracket 5 along the length of the lower longitudinal beam, and since the metal conveyor network 8 passes around the tensioning roller 6, tensioning of the metal conveyor network 8 is achieved. A deflecting roller 7, horizontally mounted on the bottom surface of the lower longitudinal beam 3, changes the direction of the metal conveyor network. The movement direction of the conveyor net 8 is adapted to meet the material's requirements for different transport directions. The metal conveyor net 8 (used for conveying fibrous materials) is arranged in an S-shape, sequentially passing through the tension roller 6 and the deflector roller 7. The deflector roller 7 is positioned between the tension roller 6 and the rear column 1' (ensuring the metal conveyor net 8 is arranged in an S-shape as it passes through the tension roller 6 and the deflector roller 7, further ensuring the tensioning effect). Several sets of adjustment mounting holes 3-1 are provided on the bottom surface of the lower longitudinal beam 3 for adjusting the tension position of the deflector roller (when the slack of the metal conveyor net 8 exceeds the adjustment stroke of the cylinder 2, the tension position of the deflector roller 7 can be adjusted to further tighten the metal conveyor net 8). The metal transport net 8 is used to reduce the frequency of replacement, which not only simplifies the operation but also extends the service life of the metal transport net 8. A limit stop 9 is arranged in front of the turning roller 7 (to limit the position of the turning roller 7 and provide an installation base for the tightening bolt 10). The limit stop 9 is equipped with a tightening bolt 10 for tightening the bearing seat of the turning roller (providing a reaction force in the horizontal direction - that is, a reaction force that balances the forward horizontal force exerted by the metal transport net 8 on the turning roller 7, so that the turning roller 7 is in a balanced state in the horizontal direction, which can effectively prevent the turning roller 7 from moving back and forth in the horizontal direction).

[0023] In this invention, the cylinder 2 is connected to the inner side of the column 1 via a rod end spherical bearing, and the cylinder 2 is connected to the tensioning bracket 5 via a single elbow joint (for easy and quick connection).

[0024] In this utility model, the position and diameter of each set of adjustment mounting holes 3-1 are consistent with the bolt holes on the bearing seat base plate supported at both ends of the turning roller 7 (ensuring smooth alignment when adjusting the tension position of the turning roller 7).

[0025] The linear guide 4 described in this utility model adopts a high load-bearing self-lubricating ball linear guide (which can ensure that the tensioning bracket 5 can move smoothly in a straight line under the pushing and pulling action of the cylinder 2, and will not tilt during the straight line movement, thus improving the reliability of use; the linear guide 4 adopts a high load-bearing self-lubricating ball linear guide, which also has the advantage of convenient maintenance). The fixed part of the linear guide 4 is installed on the top surface of the lower longitudinal beam 3, and the sliding part of the linear guide 4 is installed on the bottom surface of the tensioning bracket 5.

[0026] In this invention, the tension roller 6 and the turning roller 7 are both coated rollers with a rubber layer on their surface (this can increase the friction between the roller surface and the metal transport net 8, effectively prevent the metal transport net 8 from slipping, and ensure that the metal transport net 8 moves smoothly and transports fiber materials smoothly).

[0027] In this invention, the width of the tension roller 6 and the turning roller 7 is greater than the width of the metal transport net 8 (to reserve a certain working gap to avoid the metal transport net 8 from colliding with the tension bracket 5 and the turning roller bearing seat and causing friction).

[0028] The specific usage of this utility model is as follows:

[0029] First, assemble the present invention according to the structural description and the positional relationships shown in the attached drawings. Then, arrange the metal conveying mesh 8 in an S-shape, passing sequentially around the tension roller 6 and the turning roller 7. Next, retract the cylinder rod of the cylinder 2. Under the pulling force of the cylinder 2 and the guiding action of the linear guide rail 4, the tension bracket 5 and the tension roller 6 on the tension bracket 5 are smoothly moved forward along the length of the lower longitudinal beam until the metal conveying mesh 8 is tensioned. This lays the foundation for the smooth conveying of fiber materials and provides a prerequisite guarantee for the quality of the finished product and the reliability of the equipment operation. If the slack of the metal conveying mesh 8 exceeds the adjustment stroke of the cylinder 2, the tension position of the turning roller 7 can be further adjusted to further tighten the metal conveying mesh 8. That is, by selecting the corresponding matching adjustment mounting hole 3-1 to install the turning roller 7, the tension position of the turning roller 7 can be adjusted. This reduces the replacement frequency of the metal conveying mesh 8, which not only simplifies the operation but also extends the service life of the metal conveying mesh 8.
