Technical Field

[0001] This utility model belongs to the field of plastic woven bag testing technology, and specifically relates to a fixing mechanism for a plastic woven bag tensile load testing machine. Background Technology

[0002] The primary significance of tensile load testing for plastic woven bags lies in assessing their load-bearing capacity under tensile force, thereby ensuring their reliability and safety in practical use. Through tensile load testing, the load-bearing capacity of plastic woven bags under heavy loads, their resistance to tearing and rupture, and their ability to effectively withstand external impacts during transportation and storage, preventing damage and leakage.

[0003] Currently, existing tensile load testing machines mainly use clamps to hold both ends of plastic woven bags and then stretch them. However, during the stretching process, the plastic woven bags will gradually break due to the tensile force, and the resulting debris will fly onto the workbench and in the laboratory, which is inconvenient to clean up.

The top of the worktable has a collection cavity, and one side of the worktable has an installation groove communicating with the collection cavity. The inner wall of the installation groove is provided with a detachable baffle. A support plate is fixedly connected to the top of the worktable, and a hydraulic push rod is provided on the top of the worktable. The output shaft of the hydraulic push rod and one side of the support plate are both provided with clamping components, and the surface of the worktable is provided with a collection component.

[0006] The clamping assembly includes a mounting plate, two mounting plates are respectively fixedly connected to one side of the support plate and the output shaft end of the hydraulic push rod, and two clamping plates are provided on opposite sides of the two mounting plates. One side of the upper clamping plate is slidably connected to the surface of the mounting plate, and one side of the lower clamping plate is fixedly connected to the surface of the mounting plate.

[0007] In the above technical solution, the surface of the clamping plate is provided with a uniformly distributed first groove, and the surface of the clamping plate is provided with a second groove that is staggered with the first groove. The first groove has a semi-circular cross section, and the second groove has a rectangular cross section.

[0008] In the above technical solution, the surface of the clamping plate is further fixedly connected with a second protrusion that matches the second groove, and the surface of the clamping plate is fixedly connected with a first protrusion that matches the first groove.

[0009] In the above technical solution, further, a fixing plate is fixedly connected to both sides of the two clamping plates, a pull block is provided on the opposite side of the two fixing plates, a slide rod is fixedly connected between the two pull blocks, the slide rod passes through the two fixing plates and slides through the inner wall of the fixing plates, a second spring is fixedly connected between the lower pull block and the fixing plate, and the surface of the slide rod is provided with uniformly distributed limiting holes.

[0010] In the above technical solution, further, a limiting rod is provided on the surface of the fixing plate below. One end of the limiting rod passes through the fixing plate and extends into the interior of the adjacent limiting hole. An inclined surface is provided at the end of the limiting rod near the limiting hole. A first spring is fixedly connected between the surface of the limiting rod and the inner wall of the fixing plate.

[0011] In the above technical solution, the collecting component further includes two connecting plates fixedly connected to the surface of the mounting plate near the hydraulic push rod and symmetrically distributed. A side plate is fixedly connected to the other side of the connecting plate. A push block is fixedly connected between the two side plates.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting up a collection component, the debris that falls off the woven bag during the test can be collected and stored inside the collection chamber.

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-4 The fixing mechanism for a plastic woven bag tensile load testing machine shown includes a workbench 1, a collection cavity 101 on the top of the workbench 1, an installation groove communicating with the collection cavity 101 on one side of the workbench 1, a removable baffle 102 on the inner wall of the installation groove, a support plate 103 fixedly connected to the top of the workbench 1, a hydraulic push rod 3 on the top of the workbench 1, a clamping assembly 2 on both the output shaft of the hydraulic push rod 3 and one side of the support plate 103, and a collection assembly 4 on the surface of the workbench 1.

[0023] The clamping assembly 2 includes a mounting plate 201. The two mounting plates 201 are fixedly connected to one side of the support plate 103 and the output shaft end of the hydraulic push rod 3, respectively. Two clamping plates 202 are provided on opposite sides of the two mounting plates 201. One side of the upper clamping plate 202 is slidably connected to the surface of the mounting plate 201, and one side of the lower clamping plate 202 is fixedly connected to the surface of the mounting plate 201.

[0024] The two clamping components 2 are used to clamp the woven bag. The position of one of the clamping components 2 can be adjusted by the hydraulic push rod 3 to test the tensile load of the woven bag.

[0025] like Figures 1-4 As shown, the surface of the lower clamping plate 202 is provided with uniformly distributed first grooves 205, and the surface of the clamping plate 202 is provided with second grooves 206 that are staggered with the first grooves 205. The cross-section of the first groove 205 is semi-circular, and the cross-section of the second groove 206 is rectangular.

[0026] The surface of the upper clamping plate 202 is fixedly connected with a second protrusion 203 that matches the second groove 206, and the surface of the clamping plate 202 is fixedly connected with a first protrusion 204 that matches the first groove 205.

[0027] Two clamping plates 202 are fixedly connected to both sides of a fixing plate 208. Pull blocks 207 are provided on opposite sides of the two fixing plates 208. A sliding rod 212 is fixedly connected between the two pull blocks 207. The sliding rod 212 passes through the two fixing plates 208 and is slidably connected to the inner wall of the fixing plates 208. A second spring 211 is fixedly connected between the lower pull block 207 and the fixing plate 208. The surface of the sliding rod 212 is provided with evenly distributed limiting holes.

[0028] A limiting rod 210 is provided on the surface of the lower fixing plate 208. One end of the limiting rod 210 passes through the fixing plate 208 and extends into the interior of the adjacent limiting hole. The end of the limiting rod 210 near the limiting hole has an inclined surface. A first spring 209 is fixedly connected between the surface of the limiting rod 210 and the inner wall of the fixing plate 208.

[0029] By pulling the limiting rod 210 to separate it from the limiting hole, the limiting of the sliding rod 212 can be released. At this time, pulling the upper clamping plate 202 upward can cause the two clamping plates 202 to separate and compress the second spring 211. Simultaneously, the first protrusion 204 and the second protrusion 203 separate from the first groove 205 and the second groove 206, respectively. The end of the woven bag to be tested is placed between the two clamping plates 202, and the limiting rod 210 and the clamping plates 202 are released. At this time, under the action of the first spring 209, the limiting rod 210 can be reset and pressed tightly against the surface of the sliding rod 212. At the same time, due to the action of the second spring 211, the sliding rod 212 can be moved downward until the limiting hole corresponds with the limiting rod 210, which can then be used to test the first groove 205 and the second groove 206. A spring 209 causes the limiting rod 210 to insert into the limiting hole. However, since the end of the limiting rod 210 has a bevel, the sliding rod 212 can squeeze the bevel of the limiting rod 210 during its downward movement, causing it to separate from the limiting hole until the clamping plate 202 clamps the woven bag. At this time, the limiting rod 210 is inserted into the adjacent limiting hole, and the bottom of the limiting rod 210 cooperates with the limiting hole to limit the sliding rod 212, thereby preventing loosening during the inspection process. At the same time, the cooperation of the first protrusion 204, the second protrusion 203, the first groove 205 and the second groove 206 can enhance the clamping and limiting effect on the end of the woven bag, avoiding the situation where the inspection effect is affected by the loosening of the clamping during the inspection process.

[0030] like Figures 1-4 As shown, the collecting component 4 includes two connecting plates 406 that are fixedly connected to the surface of the mounting plate 201 near the hydraulic push rod 3 and are symmetrically distributed. A side plate 404 is fixedly connected to the other side of the connecting plate 406. A push block 405 is fixedly connected between the two side plates 404. The bottom of the push block 405 is in contact with the surface of the worktable 1. Two guide rods 407 that are symmetrically distributed are fixedly connected to the surface of the worktable 1. The connecting plate 406 is slidably connected to the surface of the guide rod 407.

[0031] The collection assembly 4 also includes a first filter screen 402 fixedly connected to the inner wall of the collection chamber 101. The top surface of the first filter screen 402 is flush with the top surface of the workbench 1, and an inlet groove is formed between one side of the first filter screen 402 and the inner wall of the collection chamber 101. An installation cavity is provided in the inner bottom wall of the collection chamber 101. A second filter screen 403 is fixedly connected to the inner wall of the installation cavity. A fan 401 located below the second filter screen 403 is provided in the inner wall of the installation cavity. An outlet hole communicating with the outside is provided in the inner wall of the installation cavity.

[0032] During the testing process, by starting the fan 401, outside air can be introduced into the installation cavity through the first filter 402, the collection chamber 101, and the second filter 403, and finally discharged through the discharge hole. During this process, the debris that falls off the woven bag during the test can be collected and stored in the collection chamber 101. The side plate 404 can reduce the range of debris splashing. At the same time, the hydraulic push rod 3 drives the push block 405 to move synchronously. During the reset process of the hydraulic push rod 3, the push block 405 can be used to push the debris trapped on the first filter 402 into the collection chamber 101 through the inlet groove for storage. The staff can periodically clean the debris stored in the collection chamber 101 by removing the baffle 102.

[0033] Working principle: The two clamping components 2 are used to clamp the woven bag. The position of one of the clamping components 2 can be adjusted by the hydraulic push rod 3 to test the tensile load of the woven bag. The debris generated during the test can be collected by the collection component 4, which reduces the problem of debris splashing and being difficult to collect after the woven bag is stretched and broken during the test.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
