Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically a limiting tension sensor for testing steel strips. Background Technology

[0002] In the field of steel strip production, processing, and quality inspection, limit tension sensors are key components for achieving accurate monitoring and position limit control of steel strip tension. They need to collect steel strip tension data in real time and transmit it to the control system to ensure processing accuracy and production safety. These sensors typically rely on wires for power supply and signal transmission.

[0003] Because the sensor needs to be moved slightly with the adjustment of the testing station during the steel strip testing process, or the wires are densely distributed when multiple sets of sensors work in parallel, and the sensor itself lacks an effective wire storage and guiding structure, the wires are very prone to tangling and knotting. Wire tangling not only leads to poor signal transmission contact, causing distortion of tension data acquisition and delay in limit control response, directly affecting the normal monitoring function of the sensor, but may even cause wire damage due to tangling and pulling, leading to equipment failure. At the same time, during the handling or carrying of the sensor, the tangled wires are difficult to organize, increasing the storage difficulty, reducing the convenience of operation, and may also shorten the service life of the wires due to long-term tangled stress. Therefore, we propose a limit tension sensor for steel strip testing. Utility Model Content

[0004] The purpose of this invention is to provide a limiting tension sensor for steel strip testing, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A limiting tension sensor for testing steel strip includes a housing, a cover plate disposed inside the housing, an elastic element placed inside the cover plate and the housing, and a wire fixedly connected to one end of the elastic element.

[0007] The bottom of the cover plate is fixedly connected with four sets of locking blocks at equal intervals, and the housing is provided with four sets of locking slots. The cover plate is locked with the locking blocks and locking slots. The front end of the housing is provided with a storage component for storing wires.

[0008] Preferably, the storage assembly includes a fixed base fixedly connected to the front surface of the housing, a winding roller rotatably connected inside the fixed base, a handwheel coaxially fixedly connected to the right end of the winding roller, two sets of movable compartments symmetrically fixedly connected to the outer wall of the fixed base, a spring fixedly connected inside the movable compartment, a positioning block fixedly connected to the other end of the spring, the positioning block slidably connected to the movable compartment, and a plurality of positioning grooves equidistantly opened on the outer wall of the handwheel, the positioning grooves engaging with the positioning blocks.

[0009] Preferably, the take-up roller has a groove, a clamping block is slidably connected in the groove, a fastening screw is rotatably connected in the clamping block, and the fastening screw is threadedly connected to the take-up roller.

[0010] Preferably, the outer end of the positioning block is designed in a semi-circular shape, and the positioning groove is a countersunk hole adapted to the positioning block.

[0011] Preferably, the portion of the positioning block inserted into the movable compartment is rectangular in shape, and the movable compartment has a rectangular groove adapted to the positioning block.

[0012] Preferably, the fastening screw has a pentagonal design, and the outer wall of the fastening screw is provided with anti-slip texture.

[0013] Preferably, the clamping block is L-shaped at one end facing the take-up roller, and an anti-slip pad is fixedly connected to the inner wall of the clamping block.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a winding roller in the storage component to orderly wind up the wire. With the limiting effect of the positioning block and positioning groove, it can effectively prevent the wire from falling off after winding. This fundamentally solves the problems of poor signal transmission and equipment failure caused by wire entanglement, ensuring the accuracy of tension data acquisition and the timeliness of limit control. The cover plate is fixed by the locking block and locking groove, which can be quickly disassembled and assembled without the aid of tools. This facilitates the inspection or replacement of internal elastic components, wires and other parts. Compared with the traditional bolt fixing method, it greatly shortens the maintenance time and improves the convenience of operation.

[0016] 2. This utility model, through the L-shaped design of the clamping block and the anti-slip soft pad, can increase the contact area with the wire, improve the clamping stability, and avoid damage to the wire sheath due to excessive clamping force. The pentagonal design and anti-slip texture of the fastening screw facilitates operation with special tools and prevents slippage, further ensuring the reliability of the structure.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a limit tension sensor for steel strip testing includes a housing 1, a cover plate 2 is provided inside the housing 1, and an elastic element 3 is placed inside the cover plate 2 and the housing 1. One end of the elastic element 3 is fixedly connected to a wire 4.

[0025] Four sets of locking blocks 6 are fixedly connected at equal intervals at the bottom of the cover plate 2. Four sets of locking grooves 7 are opened inside the housing 1. The cover plate 2 is locked with the locking blocks 6 and the locking grooves 7. A storage component 5 for storing the wire 4 is provided at the front end of the housing 1.

[0026] As a technical optimization of this utility model, the storage component 5 includes a fixed seat 51 fixedly connected to the front surface of the housing 1. A winding roller 52 is rotatably connected inside the fixed seat 51. A handwheel 53 is coaxially fixedly connected to the right end of the winding roller 52. Two sets of movable compartments 54 are symmetrically fixedly connected to the outer wall of the fixed seat 51. A spring 55 is fixedly connected inside the movable compartment 54. A positioning block 56 is fixedly connected to the other end of the spring 55. The positioning block 56 is slidably connected to the movable compartment 54. Several sets of positioning grooves 57 are equidistantly opened on the outer wall of the handwheel 53. The positioning grooves 57 are engaged with the positioning blocks 56.

[0027] In use, when it is necessary to store the wire 4, the operator turns the handwheel 53 of the storage component 5. The handwheel 53 drives the take-up roller 52 to rotate in the fixed seat 51. The wire 4 is gradually wound around the take-up roller 52. During the winding process, the spring 55 in the movable chamber 54 always pushes the positioning block 56 to fit against the outer wall of the handwheel 53. When the wire 4 is wound to the target length, the positioning block 56 is embedded in the positioning groove 57 of the handwheel 53 under the action of the spring 55, restricting the take-up roller 52 from rotating independently, thus completing the wire 4 storage limit.

[0028] As a technical optimization of this utility model, a groove 58 is provided on the take-up roller 52, a clamping block 59 is slidably connected in the groove 58, and a fastening screw 510 is rotatably connected in the clamping block 59. The fastening screw 510 is threadedly connected to the take-up roller 52.

[0029] In practice, to prevent the end of the wire 4 from falling off, the fastening screw 510 inside the clamping block 59 is rotated. The fastening screw 510 is threadedly engaged with the winding roller 52, pushing the clamping block 59 to slide along the slide groove 58 until the anti-slip soft pad on the inner wall of the clamping block 59 is tightly attached to the wire 4, thereby achieving stable fixation of the end of the wire 4.

[0030] As a technical optimization of this utility model, the outer end of the positioning block 56 is designed in a semi-circular shape, and the positioning groove 57 is opened as a countersunk hole adapted to the positioning block 56.

[0031] In practice, the semi-circular structure can reduce the jamming when the positioning block 56 and the positioning groove 57 are docked, making it easier for the positioning block 56 to smoothly insert into or remove from the positioning groove 57.

[0032] As a technical optimization of this utility model, the part of the positioning block 56 inserted into the movable compartment 54 is designed in a rectangular shape, and a rectangular groove adapted to the positioning block 56 is opened in the movable compartment 54.

[0033] In practice, the rectangular structure can restrict the positioning block 56 from rotating within the movable chamber 54, ensuring that the positioning block 56 always slides in a straight line and guarantees precise docking with the positioning groove 57.

[0034] As a technical optimization of this utility model, the fastening screw 510 is pentagonal in design, and the outer wall of the fastening screw 510 is provided with anti-slip texture.

[0035] In practice, the pentagonal fastening screw 510 and the anti-slip texture can prevent slippage during operation and ensure reliable clamping force.

[0036] As a technical optimization of this utility model, the end of the clamping block 59 facing the winding roller 52 is designed in an L shape, and the inner wall of the clamping block 59 is fixedly connected with an anti-slip soft pad.

[0037] In practice, the L-shaped design increases the contact area between the clamping block 59 and the wire 4, improves the clamping stability of the wire 4, and prevents the wire 4 from loosening during winding or use. The anti-slip pad can further increase the friction with the wire 4, while avoiding excessive clamping force that could damage the outer sheath of the wire 4 and protecting the integrity of the wire 4.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
