Abstract
Description
Technical Field
[0001] This utility model relates to the field of length measuring equipment technology, and in particular to a roll length measuring device. Background Technology
[0002] When using wound-up auxiliary materials, it is necessary to unwind them for easy use and cutting. Traditional unwinding machines cannot accurately measure the length of the cut material during the unwinding and cutting process, requiring the use of external measuring rulers. This not only increases the workload of the workers but also makes operation inconvenient. It often results in situations where more material is cut than the tooling dimensions are available, leading to material waste and increased costs due to measurement errors.
[0003] Therefore, there is an urgent need for a roll length measuring device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a roll length measuring device that can measure the unwinding length of the roll in real time, thereby reducing waste of the roll and saving production costs.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A device for measuring the length of a roll of material is provided, comprising:
[0007] A support frame, comprising a crossbeam and a column, wherein the crossbeam is threaded through the roll of material to be measured, the roll of material rotates around the crossbeam, and the column is angularly connected to the end of the crossbeam;
[0008] Mounting base, which is movably connected to the column and can be close to or away from the crossbeam;
[0009] A measuring mechanism, which abuts against the coil material;
[0010] An elastic element is connected between the mounting base and the measuring mechanism.
[0011] As an optional solution for the roll length measuring device, the measuring mechanism includes a housing and a rangefinder. The housing is connected to the elastic element, and the rangefinder is rotatably installed inside the housing and abuts against the roll.
[0012] As an alternative to the coil length measuring device, the housing includes a main body and a protrusion. The main body is used to accommodate the rangefinder, and the protrusion protrudes from the side of the main body facing the elastic member. The protrusion forms a mounting groove, and one end of the elastic member is confined within the mounting groove.
[0013] As an optional solution for the coil length measuring device, the protrusion further includes a limiting part, which is disposed on the inner wall of the mounting groove.
[0014] As an optional solution for the roll length measuring device, the measuring mechanism also includes a display element, which is signal-connected to the rangefinder.
[0015] As an alternative to the coil length measuring device, the elastic element is configured as a spring or an elastic plate.
[0016] As an optional solution for the coil length measuring device, the mounting base is configured as a switch-type magnetic base.
[0017] As an optional solution for the roll length measuring device, the roll length measuring device further includes a clamping mechanism connected to the support frame, the clamping mechanism being used to clamp the roll.
[0018] As an alternative to the coil length measuring device, the support frame includes multiple crossbeams and multiple columns, with each crossbeam connected at an angle to at least one column.
[0019] As an optional solution for the coil length measuring device, the column is provided with a slide rail, and the mounting base can move within the slide rail.
[0020] The beneficial effects of this utility model are:
[0021] This invention provides a device for measuring the length of a roll of material. The roll of material is fixed on a crossbeam, and a column is connected to one end of the crossbeam at an angle. A mounting base is movably connected to the column. A measuring mechanism is mounted on the mounting base via an elastic element. By changing the position of the mounting base on the column, the measuring mechanism can come into contact with the roll of material. When the roll of material is unwound, the measuring mechanism generates a relative displacement between the roll surface and the material. The measuring mechanism can detect the length of this relative displacement, which is the unwinding length of the roll of material. When the measuring mechanism comes into contact with the roll of material, the movable mounting base continues to move closer to the crossbeam, causing the elastic element to bend and deform. This ensures that the measuring mechanism presses the roll of material radially. Even as the roll of material unwinds and the winding radius gradually decreases, the measuring mechanism continues to press against the roll of material, preventing separation of the measuring mechanism from the roll of material and thus avoiding measurement errors and ensuring the accuracy of the measurement results. This roll length measuring device can measure the unwinding length of the roll in real time, avoiding the problem of the roll being too long or too short during unwinding, achieving the purpose of appropriate cutting, ensuring full use of materials, reducing waste of rolls, saving production costs, and also reducing the time for secondary measurement and cutting after unwinding, thus improving production efficiency.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0035] like Figures 1 to 3 As shown, the roll length measuring device of this embodiment includes a support frame 100, a mounting base 300, a measuring mechanism 400, and an elastic element 500. The support frame includes a crossbeam 110 and a column 120. The crossbeam 110 passes through the roll 200 to be measured, and the roll 200 rotates around the crossbeam 110. The column 120 is angularly connected to the end of the crossbeam 110. The mounting base 300 is movably connected to the column 120 and can move closer to or further away from the crossbeam 110. The measuring mechanism 400 abuts against the roll 200. The elastic element 500 connects the mounting base 300 and the measuring mechanism 400.
[0036] Based on the above design, the roll length measuring device fixes the roll 200 on the crossbeam 110, the column 120 is connected at an angle to one end of the crossbeam 110, the mounting base 300 is movably connected to the column 120, and the measuring mechanism 400 is mounted on the mounting base 300 through the elastic element 500. By changing the position of the mounting base 300 on the column 120, the measuring mechanism 400 can abut against the roll 200. When the roll 200 is unwound, the measuring mechanism 400 generates a relative displacement on the surface of the roll 200. The measuring mechanism 400 can detect the length of the relative displacement, which is the unwinding length of the roll 200. After the movable mounting base 300 approaches the coil 200, causing the measuring mechanism 400 to abut against the coil 200, the movable mounting base 300 continues to move towards the crossbeam 110, causing the elastic element 500 to bend and deform. This ensures that the measuring mechanism 400 presses the coil 200 tightly in the radial direction of the coil. Furthermore, as the coil 200 is unwound, causing the winding radius of the coil 200 to gradually decrease, the measuring mechanism 400 can continue to press tightly against the coil 200, preventing the measuring mechanism 400 from separating from the coil 200 and causing measurement errors, thereby ensuring the accuracy of the measurement results.
[0037] This roll length measuring device can measure the unwinding length of the roll 200 in real time, avoiding the problem of the roll 200 being too long or too short during unwinding, achieving the purpose of appropriate cutting, ensuring full utilization of the roll 200, reducing waste of the roll 200, saving production costs, and also reducing the time for secondary measurement and cutting after unwinding, thus improving production efficiency.
[0038] Optionally, a slide rail (not shown in the figure) can be provided on the column 120, and the mounting base 300 can move on the slide rail. This can not only serve as a guide to ensure the smoothness of the mounting base 300 when moving, but also support the mounting base 300 in different directions, thereby improving the stability of the mounting base 300 fixed on the column 120.
[0039] In this embodiment, the mounting base 300 is configured as a switchable magnetic base. When the magnetic base is turned on, the magnetism of the mounting base 300 disappears, allowing it to move closer to or away from the crossbeam. After determining the installation position of the mounting base 300, the switch of the magnetic base is turned off, and the magnetic base regains its magnetism, allowing it to adhere to the column 120, thus positioning the mounting base 300. The use of a switchable magnetic base makes the movement and fixation of the mounting base 300 more convenient and easier to operate. In some other embodiments, multiple slots or holes can be spaced apart on the column 120, allowing the mounting base 300 to engage with different positions on the column 120; these will not be elaborated upon here.
[0040] Optionally, the elastic element 500 can be configured as a spring or an elastic plate, which has a simple structure, is easy to install, and has low operating costs, thus reducing the cost of later maintenance and replacement.
[0041] Furthermore, the measuring mechanism 400 includes a housing 410 and a rangefinder 420. The housing 410 is connected to the elastic member 500, and the rangefinder 420 is rotatably mounted inside the housing 410, abutting against the roll 200. When the roll 200 is unwound, the rangefinder 420 can rotate with the roll 200, and the unwound length of the roll 200 can be calculated based on the number of rotations and the radius of the rangefinder 420.
[0042] Optionally, the housing 410 includes a main body 411 and a protrusion 412. The main body 411 accommodates the rangefinder 420, and the protrusion 412 protrudes from the side of the main body 411 facing the elastic member 500, forming a mounting groove 413. One end of the elastic member 500 is confined within the mounting groove 413. In this embodiment, the protrusion 412 has a U-shaped structure, allowing the elastic member 500 to enter the mounting groove 413 through the opening of the U-shaped structure, facilitating the installation of the elastic member 500.
[0043] Optionally, the protrusion 412 also includes a limiting part 4121, which is disposed on the inner wall of the mounting groove 413. The elastic member 500 can be engaged with the limiting part 4121 to ensure that part of the elastic member 500 can be fixed in the mounting groove 413, preventing the outer shell 410 from moving away from the elastic member 500 and avoiding the measuring mechanism 400 from falling off after detaching from the elastic member 500.
[0044] Optionally, the measuring mechanism 400 also includes a display element (not shown in the figure), which is connected to the rangefinder 420. The unwinding length of the roll 200 can be read directly through the display element, thereby improving the ease of use of the roll length measuring device.
[0045] Furthermore, the roll length measuring device also includes a clamping mechanism connected to the support frame 100. The clamping mechanism is used to clamp the roll 200. When the roll 200 needs to be unwound, the clamping mechanism is released, allowing the roll 200 to rotate around the crossbeam 110 for unwinding. After unwinding is completed, the clamping mechanism is used to fix the roll 200 to prevent the roll 200 from rotating and unwinding under gravity, thus ensuring the cleanliness of the roll 200.
[0046] It is understood that the support frame 100 may include multiple crossbeams 110 and multiple columns 120, with each crossbeam 110 connected at an angle to at least one column 120, so that the same support frame 100 can simultaneously unwind multiple rolls 200, saving unwinding space.
[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
