Description

Technical Field

[0001] The utility model relates to the technical field of fabric production, in particular to an elasticity detection device for composite fabric production. Background Art

[0002] Elastic fabrics are often used for outdoor sports. Their excellent stretchability makes outdoor activities more convenient and faster, while effectively protecting muscles from the strain of stretching. The fabric's stretchiness allows the garment to synchronize with the rhythm of movement, protecting the body's surface while also maximizing human capacity to push boundaries. After the finished elastic fabric is manufactured, its tensile strength needs to be tested. Existing testing devices for tensile strength testing of elastic fabrics are inaccurate, often because the fabric is not taut during testing. Furthermore, existing testing devices typically clamp the fabric with two clamps, which cannot secure the fabric in place, making it easy for the fabric to detach from the clamping mechanism during testing, reducing both accuracy and efficiency.

[0003] For example, Chinese patent publication number CN215727342U discloses an elasticity detection device for composite fabric production. The detection device is provided with adjustment components at both ends of the lower surface of the bracket. The fabric is clamped and limited by a serrated convex plate between the fixed plate and the movable plate at the bottom of the adjustment component, so that the fabric can be stably clamped and is not easily separated from the clamping mechanism during elasticity testing, thereby improving the detection accuracy of the device. The adjustment component adjusts the position of the connecting block through a screw and a screw groove, so that the fabric can remain taut after clamping, further improving the detection accuracy and efficiency of the device.

[0004] First, the serrated convex plate in the above-mentioned device increases the friction between it and the fabric, and completes the clamping of the two ends of the fabric through the up and down squeezing force. In this way, when the elastic convex head is pressed down, the two ends of the fabric sink accordingly and contact the side wall at the top of the movable plate. The edge of the side wall is easily broken due to the reduced contact area with the fabric, so the boundary line of the side wall can easily cause the fabric to break when the elastic convex head is pressed down; secondly, the material of the fabric largely determines the clamping effect of the serrated convex plate. If a fabric with a small friction coefficient such as silk is clamped with the serrated convex plate, the clamping effect is poor, and it is easy to fail to clamp during the detection process. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides an elasticity detection device for composite fabric production, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an elasticity detection device for composite fabric production, comprising an operating platform, on which an elasticity detection device is provided, the elasticity detection device comprising a roller-type limiting unit and a detection installation unit, both of which are installed on the operating platform;

[0007] The roller-type limiting unit includes limiting slides symmetrically arranged at both ends of the operating platform, and sliding grooves are provided inside the two limiting slides. The two limiting slides are slidably connected to the corresponding extension plates through the sliding grooves. The tops of the two extension plates are correspondingly welded with corresponding support seats. A limiting roller is installed between the two support seats, and the limiting roller rotates between the two support seats.

[0008] The roller-type limiting unit is designed for elastic testing of composite fabrics of different lengths. The roller design of the limiting roller allows excessively long fabrics to be evenly wound around the limiting roller. Combined with the sliding properties of the limiting slide and the extension plate, it ensures that excessively long fabrics can be quickly wound by the device during testing, eliminating the need to trim the fabrics and improving testing efficiency.

[0009] A further improvement of the technical solution of the present utility model is that: two groups of connecting rods are symmetrically arranged at both ends of the limiting roller, each of the connecting rods is welded to the limiting roller, each of the connecting rods is provided with a lower pressure groove, and a horizontal plate is slidably connected at the two groups of lower pressure grooves between the connecting rods on the same side, and the lower pressure plate is connected between the two horizontal plates by a connecting rod, the connecting rod is inserted into the lower pressure plate and the connecting rod is connected to the horizontal plate by a fastener, and an arc-shaped mosaic plate is provided at the bottom of the lower pressure plate

[0010] The horizontal plate slidably connected to the lower pressing groove drives the lower pressing plate to rise and fall and slide through the connecting rod, so that the mosaic plate connected to the bottom of the lower pressing plate clamps the composite fabric wrapped around the limiting roller. Preferably, the surface of the mosaic plate can be provided with friction patterns according to the strength of the fabric material;

[0011] Compared with the existing technology, the limiting roller has a uniform arc-shaped outer wall as a whole, so the fabric will not generate a large force with the protruding boundary of the side wall during the tightening of the composite fabric, thereby reducing the probability of the fabric area outside the detection point breaking during the gradual tightening of the composite fabric. In addition, the fabric-fitting area of ​​the mosaic plate is also arc-shaped, which again ensures that the force in each area of ​​the fabric clamping is uniform.

[0012] A further improvement of the technical solution of the present utility model is that an upper top plate is arranged above the lower pressure plate, and brackets fixedly installed on the top of the connecting rod are welded on the four sides of the upper top plate. A positioning screw is arranged at the center of the upper top plate, and the positioning screw is threadedly connected to the upper top plate. The other end of the positioning screw is rotatably connected to the lower pressure plate through a bearing.

[0013] Therefore, this device uses the roller design of the limiting roller in the roller limiting unit to ensure that the excessively long fabric can be evenly wound on the limiting roller, ensuring that the excessively long fabric can be quickly wound by the device during detection, without the need to trim the fabric, thereby improving the detection efficiency. At the same time, the limiting roller has a uniform arc-shaped outer wall as the whole, and the fabric will not generate a large force with the protruding boundary of the side wall during the tightening of the composite fabric, thereby reducing the probability of fabric breakage, improving the clamping effect of the device, and ensuring that the force in each area of ​​the fabric clamping is uniform.

[0014] A further improvement of the technical solution of the present utility model is that: the detection installation unit includes mounting seats symmetrically arranged at both ends of the operating platform, a clamping rod is installed in a limited position in one of the mounting seats, and a cylinder is provided in the other mounting seat, and the ends of the clamping rod and the cylinder close to each other are fixedly installed on the clamping disk, and a clamping roller is installed in a limited position between the two clamping disks, a material threading seat is welded on the clamping roller, and a material threading groove is provided in the material threading seat.

[0015] After one end of the fabric is wound around the limiting roller, it is limited by the arc-shaped interlocking plate. Then the other end of the composite fabric is wound around the clamping roller through the feeding slot. Therefore, during the elastic force detection process, the pressure detector and the downward pressure of the elastic protrusion are removed, and only the splicing clamping roller is continuously wound until the fabric breaks. In this process, according to M=Fd in material mechanics, M is the bending moment, F is the external torque force received by the clamping roller, and d is the distance between the clamping roller and the limiting roller during the fabric tensioning process, the bending moment M is obtained, and thus the maximum value of the elastic torsion of the composite fabric is obtained, rather than being limited to the elastic force detection of the partial area where the elastic protrusion is pressed down.

[0016] A further improvement of the technical solution of the present invention is that threaded rods are symmetrically arranged above the material threading seat, the material threading seat is threadedly connected to each threaded rod, and a limiting plate is rotatably installed at the bottom of each threaded rod.

[0017] Therefore, by installing the clamping roller and the limiting roller in the unit to limit the rotation of the composite fabric, the elastic force detection of the entire composite fabric can be achieved, avoiding the elastic force detection being limited to the partial area where the elastic convex head is pressed down, and the detection effect is more comprehensive and accurate.

[0018] A further improvement of the technical solution of the present invention is that: a mounting plate is vertically fixed on the top of the two support seats, a hydraulic push rod is provided at the middle of the mounting plate, an elastic convex head is provided at the bottom of the hydraulic push rod, and a pressure detector for detection is provided on the elastic convex head.

[0021] 1.

At the same time, because the overall outer wall of the limiting roller is a uniform arc, the composite fabric will not generate a large force against the protruding boundary of the side wall during the tightening process, thereby reducing the probability of fabric breakage, improving the clamping effect of the device, and ensuring that the force in each area of ​​the fabric clamping is uniform.

[0022] 2. The elasticity detection device for composite fabric production realizes elasticity detection of the entire composite fabric by cooperating with the clamping roller and the limiting roller in the installation unit to limit the rotation of the composite fabric, avoiding elasticity detection limited to the partial area pressed down by the elastic convex head, and its detection effect is more comprehensive and accurate.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1-Figure 4, this utility model provides three technical solutions:

[0030] Example 1:

[0031] An elasticity detection device for composite fabric production includes an operating platform 1, on which an elasticity detection device is provided. The elasticity detection device includes a roller-type limiting unit and a detection installation unit, both of which are installed on the operating platform 1.

[0032] The roller-type limiting unit includes a limiting slide 201 symmetrically arranged at both ends of the operating platform 1. A sliding groove 202 is provided inside the two limiting slides 201. The two limiting slides 201 are slidably connected to the corresponding extension plates 203 through the sliding groove 202. The tops of the two extension plates 203 are correspondingly welded with corresponding support seats 204. A limiting roller 205 is installed between the two support seats 204, and the limiting roller 205 rotates between the two support seats 204.

[0033] In this embodiment, the roller-type limiting unit is used for elastic force detection of composite fabrics of different lengths. The roller-type design of the limiting roller 205 allows excessively long fabrics to be evenly wound on the limiting roller 205, and combined with the sliding properties of the limiting slide 201 and the extension plate 203, it is ensured that excessively long fabrics can be quickly wound by the device during detection without trimming the fabrics, thereby improving detection efficiency.

[0034] Example 2:

[0035] On the basis of Example 1: two sets of connecting rods 206 are symmetrically arranged at both ends of the limiting roller 205, each connecting rod 206 is welded to the limiting roller 205, each connecting rod 206 is provided with a lower pressing groove 207, and the two sets of lower pressing grooves 207 between the connecting rods 206 on the same side are slidably connected with a horizontal plate 208, and the two horizontal plates 208 are connected to the lower pressing plate 210 through a connecting rod 209, and the connecting rod 209 is inserted into the lower pressing plate 210 and connected to the horizontal plate 208 by a fastener. The bottom of the lower pressing plate 210 is provided with an arc-shaped interlocking plate 214

[0036] In this embodiment, the horizontal plate 208 slidably connected to the lower pressing groove 207 drives the lower pressing plate 210 to rise and slide through the connecting rod 209, so that the mosaic plate 214 connected to the bottom of the lower pressing plate 210 clamps the composite fabric wrapped around the limiting roller 205. Preferably, the surface of the mosaic plate 214 can be provided with friction patterns according to the strength of the fabric material.

[0037] Compared with the prior art, the limiting roller 205 has a uniform arc-shaped outer wall as a whole, so the fabric will not generate a large force with the protruding boundary of the side wall during the tightening of the composite fabric, thereby reducing the probability of the fabric area outside the detection point breaking during the gradual tightening of the composite fabric. In addition, the fabric-fitting area of ​​the mosaic plate 214 is also arc-shaped, which again ensures that the force in each area of ​​the fabric clamping is uniform.

[0038] An upper plate 211 is provided above the lower pressure plate 210. Brackets 212 fixedly mounted on the top of the connecting rod 206 are welded on the four sides of the upper plate 211. A positioning screw 213 is provided at the center of the upper plate 211. The positioning screw 213 is threadedly connected to the upper plate 211, and the other end of the positioning screw 213 is rotatably connected to the lower pressure plate 210 through a bearing.

[0039] Therefore, this device uses the roller design of the limiting roller 205 in the roller limiting unit to ensure that the excessively long fabric can be evenly wound around the limiting roller 205, ensuring that the excessively long fabric can be quickly wound by the device during detection, without the need to trim the fabric, thereby improving the detection efficiency. At the same time, the limiting roller 205 has a uniform arc-shaped outer wall as a whole, and during the process of tightening the composite fabric, the fabric will not generate a large force with the protruding boundary of the side wall, thereby reducing the probability of fabric breakage, improving the clamping effect of the device, and ensuring that the force in each area of ​​the fabric clamping is uniform.

[0040] Example 3:

[0041] On the basis of Example 1 and Example 2: the detection installation unit includes mounting seats 301 symmetrically arranged at both ends of the operating platform 1, a clamping rod 302 is installed in a limiting position in one of the mounting seats 301, and a cylinder 303 is provided in the other mounting seat 301, and the ends of the clamping rod 302 and the cylinder 303 close to each other are fixedly installed on the clamping disk 304, and a clamping roller 305 is installed between the two clamping disks 304, and a material threading seat 306 is welded on the clamping roller 305, and a material threading groove is provided in the material threading seat 306.

[0042] In this embodiment, after one end of the fabric is wound around the limiting roller 205, it is limited by the arc-shaped interlocking plate 214, and then the other end of the composite fabric is wound around the clamping roller 305 through the feeding groove. Therefore, during the elastic force detection process, the pressure detector and the downward pressure of the elastic protrusion 311 are removed, and only the continuous winding of the clamping roller 305 is performed until the fabric breaks. In this process, according to M=Fd in material mechanics, M is the bending moment, F is the external torque force received by the clamping roller 305, and d is the distance between the clamping roller 305 and the limiting roller 205 during the fabric tensioning process, the bending moment M is obtained, thereby obtaining the maximum value of the elastic torsion of the composite fabric, rather than being limited to the elastic force detection of the partial area where the elastic protrusion 311 is pressed down.

[0043] Threaded rods 307 are symmetrically arranged above the material threading seat 306. The material threading seat 306 is threadedly connected to each threaded rod 307, and a limiting plate 308 is rotatably installed at the bottom of each threaded rod 307.

[0044] Therefore, the present invention realizes elastic force detection of the entire composite fabric by cooperating with the clamping roller 305 and the limiting roller 205 in the installation unit to limit the rotation of the composite fabric, avoiding elastic force detection limited to the partial area pressed down by the elastic protrusion 311, and its detection effect is more comprehensive and accurate.

[0045] The tops of the two support seats 204 are both vertically fixed with mounting plates 309 , a hydraulic push rod 310 is provided in the middle of the mounting plate 309 , an elastic protrusion 311 is provided at the bottom of the hydraulic push rod 310 , and a pressure detector for detection is provided on the elastic protrusion 311 .

[0047] When in use, one end of the fabric is wrapped around the limiting roller 205, and the other end is wound around the clamping roller 305 through the feeding groove. At this time, the position of the extension plate 203 in the sliding groove 202 is adjusted according to the overall length of the fabric, and the horizontal plate 208 slidably connected to the lower pressing groove 207 drives the lower pressing plate 210 to rise and slide through the connecting rod 209. The interlocking plate 214 connected to the bottom of the lower pressing plate 210 clamps the composite fabric wrapped around the limiting roller 205. At this time, the rotation of the threaded rod 307 drives the limiting plate 308 to clamp the composite fabric on the clamping roller 305, starts the hydraulic push rod 310, and the elastic protrusion 311 presses down on the fabric. The set pressure detector detects during the gradual downward pressure.
