Description

Technical Field

[0001] This utility model relates to the field of tension measurement technology, and in particular to a tension measurement device. Background Technology

[0002] Transmission belts, as commonly used transmission components in modern machinery, are widely used in various applications requiring precise motion and power transmission, such as conveyors, printing equipment, and automotive production lines. The performance and lifespan of a transmission belt largely depend on its stress state, i.e., the proper control of its tension. Insufficient tension will cause slippage during operation, affecting transmission efficiency and accuracy; excessive tension will accelerate belt aging and wear, shortening its service life. Therefore, it is necessary to measure the tension of the transmission belt to ensure it is under appropriate tension.

[0003] Currently, belt tension measurement technologies are mainly divided into two categories: contact and non-contact. Existing contact methods primarily rely on the direct contact between the gauge and the belt, utilizing mechanical principles or force transmission to directly measure tension. However, this method requires measurement on the actual belt, and due to application limitations, the gauge is prone to tilting relative to the belt during use, compromising measurement accuracy. Utility Model Content

[0004] The main objective of this invention is to provide a tension measuring device that aims to improve the accuracy of contact tension measurement.

[0005] To achieve the above objectives, the present invention proposes a tension measuring device for measuring the tension of a transmission belt, wherein the transmission belt is mounted on a base, and includes:

[0006] Mounting base;

[0007] A tension gauge is slidably mounted on the mounting base, allowing the test head of the tension gauge to press against or move away from the transmission belt; and

[0008] A positioning component is disposed on the mounting base and extends away from the tension gauge, the positioning component being used to position the mounting base on the base such that the test head of the tension gauge is perpendicular to the drive belt.

[0009] In one embodiment, the positioning component includes a positioning plate, the base has a first side parallel to the transmission belt and a second side adjacent to the first side, the mounting base is in contact with the second side, and the positioning plate is in contact with the first side.

[0010] In one embodiment, the test head of the tension meter faces one end of the mounting base, and the positioning plate is located at the other end of the mounting base and protrudes in a direction away from the tension meter.

[0011] In one embodiment, the base is provided with a positioning part, which is disposed on the same side as the transmission belt, and the side of the mounting seat is used to abut against the positioning part.

[0012] In one embodiment, the tension measuring device further includes:

[0013] Guide rail, provided on the mounting base; and

[0014] An adapter plate is slidably mounted on the guide rail, and the tension sensor is located on the side of the adapter plate opposite to the mounting base.

[0015] In one embodiment, the tension measuring device further includes:

[0016] A fixing plate is disposed at one end of the adapter plate and is perpendicular to the adapter plate. The fixing plate is used to fix the tension sensor.

[0017] In one embodiment, the tension measuring device further includes:

[0018] A limiting component is provided on the side of the mounting base where the guide rail is located. The limiting component can abut against the adapter plate to limit the sliding stroke of the adapter plate.

[0019] In one embodiment, the limiting component includes a first limiting member and a second limiting member spaced apart along the sliding direction of the adapter plate, with the adapter plate located between the first limiting member and the second limiting member.

[0038] Transmission belts, as commonly used transmission components in modern machinery, are widely used in various applications requiring precise motion and power transmission, such as conveyors, printing equipment, and automotive production lines. The performance and lifespan of a transmission belt largely depend on its stress state, i.e., the proper control of its tension. Insufficient tension will cause slippage during operation, affecting transmission efficiency and accuracy; excessive tension will accelerate belt aging and wear, shortening its service life. Therefore, it is necessary to measure the tension of the transmission belt to ensure it is under appropriate tension.

[0039] Currently, belt tension measurement technologies are mainly divided into two categories: contact and non-contact. Existing contact methods primarily rely on the direct contact between the gauge and the belt, utilizing mechanical principles or force transmission to directly measure tension. However, this method requires measurement on the actual belt, and due to application limitations, the gauge is prone to tilting relative to the belt during use, compromising measurement accuracy.

[0040] This invention proposes a tension measuring device to improve measurement accuracy.

[0041] Please see Figures 1 to 4In one embodiment, the tension measuring device includes a mounting base 100, a tension sensor 200, and a positioning component. The tension sensor 200 is slidably disposed on the mounting base 100, such that the test head 210 of the tension sensor 200 can press against or move away from the transmission belt 01. The positioning component is disposed on the mounting base 100 and extends away from the tension sensor 200. The positioning component is used to position the mounting base 100 on the base 02 so that the test head 210 of the tension sensor 200 is perpendicular to the transmission belt 01.

[0042] The tension measuring device is used to measure the tension of the transmission belt 01, which is mounted on the base 02. The base 02 can be a mounting platform or mounting plate in the equipment, and the equipment can be testing equipment, storage equipment, processing equipment, etc. The transmission belt 01 can be a synchronous belt or a conveyor belt, etc. There are no restrictions here.

[0043] The tension gauge 200 is used for contact tension detection of the transmission belt 01. The mounting base 100 provides a mounting foundation for the tension gauge 200 and restricts and guides its movement. In one embodiment, the mounting base 100 is configured as a plate-like structure with parallel and opposite top and bottom surfaces. The tension gauge 200 is disposed on the top surface of the mounting base 100 and can slide back and forth along the length of the mounting base 100. Further, in one embodiment, the mounting base 100 may also include two parallel plate-like structures and a support block connecting the two plate-like structures. The opposite sides of the two plate-like structures are the top and bottom surfaces, respectively. The support block is used to raise the height of the tension gauge 200 relative to the transmission belt 01 to ensure that the tension gauge 200 is directly aligned with the transmission belt 01. The tension gauge 200 has a measuring range of 20 kg / 200 N to ensure that its measurement range can accommodate the common tension ranges of the transmission belt 01. Of course, in other embodiments, the range of the tension meter 200 can be flexibly selected according to actual needs, and no limitation is made here. When performing tension measurement, the bottom surface of the mounting base 100 is in contact with the base 02 to ensure that the tension meter 200 is perpendicular to the transmission belt 01. The tension meter 200 is manually pushed to slide along the mounting base 100 so that the test head 210 presses against the transmission belt 01 to perform tension detection on the transmission belt 01.

[0044] When the tension gauge 200 is manually pushed, the mounting base 100 is prone to tilting relative to the transmission belt 01 under the influence of external force, which in turn causes the test head 210 to tilt. A positioning component is used to position the mounting base 100 to further ensure that the test head 210 is perpendicular to the transmission belt 01. The positioning component extends away from the tension gauge 200 and can abut against the base 02 while the mounting base 100 is in contact with it. The positioning component and the mounting base 100 cooperate with the base 02 to ensure that the test head 210 is perpendicular to the transmission belt 01.

[0045] The technical solution of this utility model, by setting a mounting base 100, a tension detector 200, and a positioning component in the tension measuring device, allows the tension detector 200 to slide on the mounting base 100, enabling the test head 210 of the tension detector 200 to press against or move away from the transmission belt 01. The positioning component is located on the mounting base 100 and extends away from the tension detector 200. The positioning component is used to position the mounting base 100 on the base 02 so that the test head 210 of the tension detector 200 is perpendicular to the transmission belt 01. Compared with the prior art of directly using a detector for tension measurement, the technical solution of this utility model sets up a mounting base 100 and a positioning component. The positioning component can position the mounting base 100 on the base 02, allowing the tension detector 200 to move stably along the mounting base 100 to approach and press against the transmission belt 01. The positioning component can ensure that the test head 210 of the tension detector 200 is always perpendicular to the transmission belt 01, thereby improving the accuracy of contact tension measurement.

[0046] Please see Figures 2 to 4 In one embodiment, the positioning component includes a positioning plate 300, a base 02 having a first side 021 parallel to the transmission belt 01 and a second side 022 adjacent to the first side 021, a mounting base 100 and the second side 022 being in contact, and a positioning plate 300 being in contact with the first side 021.

[0047] Specifically, in one embodiment, the transmission belt 01 is disposed on the second side surface 022, the first side surface 021 is perpendicular to the second side surface 022, and the positioning plate 300 is perpendicular to the mounting base 100. The first side surface 021 and the second side surface 022 provide a reference surface for positioning the tension measuring device. During tension detection, precise positioning can be achieved simply by making the mounting base 100 parallel and in contact with the second side surface 022, and the positioning plate 300 parallel and in contact with the first side surface 021. The tension meter 200 is manually pushed along the mounting base 100 to make the test head 210 press against the transmission belt 01. During this process, the mounting base 100 is restricted by the positioning plate 300 and remains perpendicular to the transmission belt 01 to ensure that the test head 210 remains perpendicular to the transmission belt 01. The length of the mounting base 100 is adapted to the distance between the transmission belt 01 and the first side surface 021 to ensure that the tension meter 200 can slide along the mounting base 100 and abut against the transmission belt 01. Furthermore, in one embodiment, the base 02 is provided with a positioning hole located on the second side 022. The positioning component also includes a positioning block, which protrudes from the side of the mounting base 100 facing the second side 022 to be inserted into the positioning hole for further positioning of the mounting base 100. Here, no limitation is made.

[0048] The technical solution of this utility model embodiment, by setting a positioning plate 300 and utilizing the first side 021 and the second side 022, can accurately and quickly position the tension detector 200, which is simple to operate and improves ease of use; and the mounting base 100 and the positioning plate 300 are respectively attached to the second side 022 and the first side 021 to achieve positioning; in addition, in existing equipment, the base 02 usually has a first side 021 parallel to the transmission belt 01 and a second side 022 adjacent to the first side 021, without the need for additional modifications to the equipment or device. Therefore, this tension measuring device can be applied to a variety of different equipment, overcoming the limitations of the application scenarios of tension measuring devices in the prior art.

[0049] Please see Figure 2 and Figure 3 In one embodiment, the test head 210 of the tension meter 200 faces one end of the mounting base 100, and the positioning plate 300 is located at the other end of the mounting base 100 and protrudes in a direction away from the tension meter 200.

[0050] Specifically, the positioning plate 300 is located at the end of the mounting base 100 away from the transmission belt 01. The end of the positioning plate 300 near the tension sensor 200 is connected to the end of the mounting base 100, and the other end of the positioning plate 300 protrudes from the mounting base 100 to abut against the first side surface 021. The positioning plate 300 can be connected to the mounting base 100 by welding or screwing, etc., and there are no restrictions on this.

[0051] The technical solution of this utility model embodiment is to place the positioning plate 300 at the other end of the mounting base 100 so that the bottom surface of the mounting base 100 can be completely attached to the second side surface 022, thereby increasing the contact area between the mounting base 100 and the second side surface 022 and improving the positioning stability.

[0052] Please see Figure 3 and Figure 4 In one embodiment, the base 02 is provided with a positioning part 03, which is disposed on the same side as the transmission belt 01, and the side of the mounting seat 100 is used to abut against the positioning part 03.

[0053] Specifically, the positioning part 03 and the transmission belt 01 are located on the same side of the base 02. The positioning part 03 has a positioning surface 031, which is perpendicular to the transmission belt 01. The side of the mounting base 100 that is adjacent to both the top and bottom surfaces can be in contact with the positioning surface 031 to prevent the mounting base 100 from moving in a direction parallel to the transmission belt 01. The positioning part 03 can be a column, a bracket, or a plate-like structure, etc., and there is no limitation here.

[0054] When performing tension measurement, first, the mounting base 100 and the second side 022 are attached together, the positioning plate 300 and the first side 021 are attached together, and the side of the mounting base 100 is made to abut against the positioning surface 031 to ensure that the tension meter 200 is perpendicular to the transmission belt 01; then, the tension meter 200 is manually pushed to slide along the mounting base 100 so that the test head 210 presses against the transmission belt 01 to perform tension measurement on the transmission belt 01.

[0055] The technical solution of this utility model embodiment is to position the mounting base 100 by abutting the side of the mounting base 100 against the positioning part 03, thereby positioning the tension detector 200 and further ensuring the accuracy of the measurement.

[0056] Please see Figure 2 and Figure 3 In one embodiment, the tension measuring device further includes a guide rail 410 and an adapter plate. The guide rail 410 is disposed on the mounting base 100; the adapter plate is slidably disposed on the guide rail 410, and the tension detector 200 is disposed on the side of the adapter plate away from the mounting base 100.

[0057] Specifically, the guide rail 410 is disposed on the top surface of the mounting base 100 and extends along the length direction of the mounting base 100; that is, the guide rail 410 is a linear guide rail 410. In one embodiment, the adapter plate includes a sliding block 421 and a bearing block 422 stacked together. The sliding block 421 has a groove for sliding connection with the guide rail 410, and the bearing block 422 is fixed to the side of the sliding block 421 opposite to the guide rail 410. The bearing block 422 and the sliding block 421 are connected by bonding, snap-fitting, or welding; or, the bearing block 422 and the sliding block 421 are integrally formed. No limitation is imposed here. Of course, in other embodiments, a guide groove extending along the length direction of the mounting base 100 may also be provided on the top surface of the mounting base 100, and the adapter plate may slide on the guide groove. No limitation is imposed here.

[0058] The technical solution of this utility model embodiment, by setting the guide rail 410 and the adapter plate, can provide guidance for the sliding of the tension detector 200, realize the linear reciprocating motion of the tension detector 200, and further ensure that the test head 210 of the tension detector 200 is always perpendicular to the transmission belt 01 during the working process.

[0059] Please see Figure 3 In one embodiment, the tension measuring device further includes a fixing plate 430, which is disposed at one end of the adapter plate and perpendicular to the adapter plate. The fixing plate 430 is used to fix the tension detector 200.

[0060] Specifically, one end of the fixing plate 430 is fixed to the bearing block 422, and the other end of the fixing plate 430 extends away from the mounting base 100 to connect with the side of the tension sensor 200, thereby fixing the tension sensor 200 to the adapter plate. In one embodiment, both the housing of the tension sensor 200 and the fixing plate 430 are provided with threaded holes to fix the tension sensor 200 to the fixing plate 430 with screws. Of course, in other embodiments, the fixing plate 430 and the housing of the tension sensor 200 can also be connected by snap-fit ​​or welding, etc., which is not limited here. The fixing plate 430 and the adapter plate can be connected by screws or welding, etc., or the fixing plate 430 and the adapter plate can be integrally formed, which is not limited here.

[0061] The technical solution of this utility model embodiment, by setting a fixing plate 430 perpendicular to the adapter plate, makes the connection operation between the fixing plate 430 and the tension sensor 200 easier to realize, improves the ease of assembly, facilitates fixing the tension sensor 200 to the adapter plate, avoids affecting the sliding of the adapter plate, and improves the reliability of use.

[0062] Please see Figure 2 In one embodiment, the tension measuring device further includes a limiting component disposed on the side of the mounting base 100 where the guide rail 410 is provided. The limiting component can abut against the adapter plate to limit the sliding stroke of the adapter plate.

[0063] Specifically, in one embodiment, the limiting component includes a first limiting member 510 and a second limiting member 520 spaced apart along the sliding direction of the adapter plate, with the adapter plate located between the first limiting member 510 and the second limiting member 520.

[0064] The first limiting member 510 and the second limiting member 520 abut against the two ends of the adapter plate along its length, respectively, to limit the sliding stroke of the adapter plate, thereby limiting the sliding stroke of the tension detection element. The first limiting member 510 is located at the end of the sliding block 421 facing the transmission belt 01, and the second limiting member 520 is located at the end of the sliding block 421 facing away from the transmission belt 01. When the positioning plate 300 is in contact with the first side surface 021, the distance from the second limiting member 520 to the transmission belt 01 is equal to the distance from the end of the sliding block 421 away from the transmission belt 01 to the test head 210. During measurement, the tension meter 200 is first positioned by the positioning plate 300 and the mounting base 100, and the sliding block 421 is brought into contact with the second limiting member 520. At this time, the test head 210 is in contact with the transmission belt 01 but does not press against it. Then, the tension meter 200 is pushed towards the transmission belt 01 until the sliding block 421 is brought into contact with the first limiting member 510. The tension value measured by the tension meter 200 at this time is the tension of the transmission belt 01.

[0065] In one embodiment, the allowable positioning overshoot of the transmission belt 01 is 7mm. That is, under full load and rated tension, to ensure that the belt teeth do not skip and the belt body does not permanently elongate, the maximum allowable pushing / pulling load movement of the transmission belt 01 is 7mm. Therefore, the distance between the first limiting member 510 and the second limiting member 520 minus the length of the sliding block 421 is 7mm, to ensure that the maximum sliding stroke of the tension sensor 200 is 7mm, avoiding damage to the transmission belt 01 during measurement. Of course, in other embodiments, the allowable positioning overshoot of the transmission belt 01 can also be 8mm or 10mm, etc., as long as the distance between the first limiting member 510 and the second limiting member 520 minus the length of the sliding block 421 is equal to the allowable positioning overshoot. Here, no limitation is made.

[0066] In one embodiment, the limiting component may include only the first limiting member 510, which limits the sliding stroke of the tension sensor 200 by limiting the distance between the first limiting member 510 and the transmission belt 01. A preferred embodiment of the limiting component includes both the first limiting member 510 and the second limiting member 520, which prevents the sliding block 421 from disengaging from the guide rail 410 and allows for more precise sliding of the tension sensor 200.

[0067] Furthermore, in one embodiment, both the first limiting member 510 and the second limiting member 520 are configured as limiting screws. The limiting screws are directly nailed to the top surface of the mounting base 100 and partially exposed outside the mounting base 100 to abut against the sliding block 421.

[0068] In another embodiment, both the first limiting member 510 and the second limiting member 520 are configured as limiting blocks. The limiting blocks protrude toward the tension sensor 200. The limiting blocks can be limiting posts, limiting plates, or limiting protrusions fixed to the mounting base 100. The limiting posts, limiting protrusions, and limiting plates can be plugged into, welded to, or integrally formed with the mounting base 100; no restrictions are placed here.

[0069] The technical solution of this utility model embodiment, by setting a limiting component, can limit the sliding stroke of the tension detector 200, thereby improving the reliability of the tension measuring device; by setting the limiting component as a first limiting member 510 and a second limiting member 520, it can provide an extreme position for the sliding of the tension detector 200, so as to more accurately limit the sliding of the tension detector 200, further improving the ease of operation and reliability of the tension measuring device.

[0070] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
