Description

Technical Field

[0001] This utility model relates to the field of steel strip production technology, specifically to an automatic steel strip tension measuring machine. Background Technology

[0002] Steel strip tension testing is the process of detecting the tension applied to the steel strip during its production and processing. Appropriate tension ensures smooth steel strip transmission and precise processing, and is a crucial step in ensuring product quality and smooth production.

[0003] Utility model patent CN212363525U discloses a tension detection roller for a calendering machine used in steel strip production. This tension detection roller includes a main support frame with two guide rollers symmetrically arranged above it. Vertical plates are installed at both ends of the guide rollers on the upper surface of the main support frame. Port grooves are formed on the vertical plates, and an inner clamp is engaged above the port groove. The inner clamp can move up and down within the port groove. A pressure sensor is installed between the inner clamp and the bottom of the port groove. Rotating shafts are installed at both ends of the guide rollers, and these shafts are rotatably mounted on the inner clamp via bearings. This tension detection roller for steel strip production is suitable for steel strip production. By adding a tension detection roller during steel strip production, i.e., by installing pressure sensors below both ends of the guide rollers, the pressure sensors can sense the pressure on the guide rollers when the guide rollers are transmitting the steel strip. This pressure is proportional to the tension of the steel strip, allowing the tension of the steel strip to be determined based on this pressure. This enables adjustments to the steel strip tension as needed, improving the quality of the finished steel strip product.

[0004] The tension detection roller of the current steel strip production calender can only sense the pressure on the guide roller through a pressure sensor to understand the steel strip tension. It does not have a dedicated tension adjustment mechanism, so it cannot actively and conveniently adjust the steel strip tension. It is difficult to adjust the tension of the steel strip in real time according to the actual detection situation. In view of this, we propose an automatic steel strip tension measuring machine. Utility Model Content

[0005] The purpose of this invention is to provide an automatic tension measuring machine for steel strips to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic tension measuring machine for steel strip includes a pair of base frames. A tension measuring mechanism for detecting the tension of the steel strip is mounted on each base frame. A tension adjusting mechanism is located in front of the tension measuring mechanism. The tension adjusting mechanism includes a pair of support frames fixed in a front-to-back direction between the two base frames, several fixed rollers abutting against the bottom surface of the steel strip, and several pressure rollers abutting against the top surface of the steel strip. An end plate is fixed between the tops of the two support frames. The fixed rollers are horizontally positioned above the two base frames and are fixed relative to the positions of the base frames. The pressure rollers are rotatably connected to the bottom of a movable seat located below the end plate. Several guide posts are fixed to the top of the movable seat. A pressure plate is located above the movable seat. The guide posts pass upward through the pressure plate and the end plate in sequence. A spring is sleeved on the outside of the guide posts between the movable seat and the pressure plate. A pressure rod is threadedly connected to the end plate, and the bottom end of the pressure rod abuts against the top surface of the pressure plate.

[0008] Preferably, the tension measuring mechanism includes a pair of fixed frames fixed in a front-to-back direction between the two base frames, rollers rotatably connected to the two fixed frames respectively, and a tension measuring roller disposed between the two rollers. The two rollers abut against the bottom surface of the steel strip, and the tension measuring roller abuts against the top surface of the steel strip.

[0009] In this setup, the idler rollers support the steel strip, and the tension measuring rollers work in conjunction with the idler rollers to apply the tension of the steel strips to the tension measuring rollers, thus providing conditions for tension detection.

[0010] Preferably, a pair of crossbars are fixed between the two fixed frames, and the two ends of the tension measuring roller are rotatably connected to two bearing seats respectively. The bearing seats are installed at the bottom of the crossbars, and a pressure sensor is provided between the bearing seats and the crossbars.

[0011] In this setup, the crossbar provides the mounting base for the bearing housing, which enables the rotational connection of the tension measuring roller. The pressure sensor can sense the pressure transmitted by the tension measuring roller, thereby enabling the detection of the steel strip tension.

[0012] Preferably, the fixed roller is rotatably connected between two protrusions, and the two protrusions are respectively fixedly connected to the two base frames;

[0013] In this configuration, the boss stably mounts the fixed roller on the base frame, ensuring the fixed roller is in a fixed position and providing stable support for the steel strip.

[0014] Preferably, the fixed roller and the pressure roller are positioned correspondingly, and the steel strip is pressed between the fixed roller and the pressure roller;

[0015] In this setup, the fixed roller and the pressure roller work together to squeeze the steel strip, and the tension of the steel strip can be adjusted by changing the pressure.

[0016] Preferably, the guide post is slidably connected to the end plate and the guide post is slidably connected to the abutment plate. When the abutment rod is tightened, the abutment rod presses down on the abutment plate, causing the abutment plate to compress the spring downward, thereby increasing the pressure of the pressure roller on the steel strip.

[0017] In this setup, the guide column ensures smooth movement of the abutment and movable seat, the spring transmits pressure through deformation, and tightening the abutment rod adjusts the pressure of the pressure roller on the steel strip, thus achieving tension adjustment.

[0018] Preferably, the abutment has a threaded rod structure, and a lever is provided at the top of the abutment;

[0019] Preferably, a plurality of levers are fixed on the outer peripheral surface of the lever, and the levers are the force-applying parts for rotating the lever;

[0020] In these two settings, the threaded rod-shaped stop is easy to adjust in position by rotation, and the handle and lever make it easy for the operator to apply force, making the rotation of the stop more convenient.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This automatic steel strip tension measuring machine, by setting a tension adjustment mechanism in front of the tension measuring mechanism, can easily adjust the pressure of the pressure roller on the steel strip through the cooperation of structures such as the pressure rod, pressure plate, and spring, thereby realizing the active adjustment of the steel strip tension. It can adjust in real time according to the detection results of the tension measuring mechanism to keep the steel strip tension within a suitable range. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] Please see Figure 1 and Figure 2 An automatic tension measuring machine for steel strip includes a pair of base frames 100. A tension measuring mechanism 200 for detecting the tension of a steel strip 300 is mounted on each base frame 100. The tension measuring mechanism 200 includes a pair of fixed frames 210 fixed in a front-rear direction between the two base frames 100, rollers 211 rotatably connected to the two fixed frames 210, and a tension measuring roller 213 disposed between the two rollers 211. The two rollers 211 rest against the bottom surface of the steel strip 300, and the tension measuring roller 213 rests against the top surface of the steel strip 300. A pair of crossbars 212 are fixed between the fixed frames 210. The two ends of the tension measuring roller 213 are rotatably connected to two bearing seats 2131 respectively. The bearing seats 2131 are installed at the bottom of the crossbars 212. A pressure sensor 2132 is provided between the bearing seats 2131 and the crossbars 212. The pressure sensor 2132 can sense the pressure on the tension measuring roller 213 by the squeezing force of the steel strip 300. This pressure is related to the tension of the steel strip 300, thereby realizing the detection of the tension of the steel strip 300.

[0037] In this embodiment of the automatic steel strip tension measuring machine, firstly, the steel strip 300 passes between two idler rollers 211 and the tension measuring roller 213. The idler rollers 211 support the bottom surface of the steel strip 300, and the tension measuring roller 213 abuts against the top surface of the steel strip 300. Then, the tension of the steel strip 300 acts on the tension measuring roller 213, causing the tension measuring roller 213 to be subjected to pressure. Next, this pressure is transmitted to the pressure sensor 2132 through the bearing seat 2131. Finally, the pressure sensor 2132 converts the pressure signal into an electrical signal, thereby detecting the tension of the steel strip 300.

[0038] Example 2

[0039] In order to adjust the tension of the steel strip 300, such as Figure 1 and Figures 3-6 As shown, a tension adjustment mechanism 400 is provided in front of the tension measuring mechanism 200. The tension adjustment mechanism 400 includes a pair of support frames 410 fixed in the front-back direction between two base frames 100, a number of fixed rollers 420 abutting against the bottom surface of the steel strip 300, and a number of pressure rollers 430 abutting against the top surface of the steel strip 300. The fixed rollers 420 and the pressure rollers 430 are positioned correspondingly. The steel strip 300 is squeezed between the fixed rollers 420 and the pressure rollers 430. The fixed rollers 420 provide stable bottom support for the steel strip 300, and the pressure rollers 430 apply pressure to the steel strip 300 from the top. The two work together to form a clamping effect on the steel strip 300. By changing the pressure of the pressure rollers 430, the tension state of the steel strip 300 can be directly affected, providing basic structural support for tension adjustment.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the fixed roller 420 is rotatably connected between two protrusions 421. The two protrusions 421 are fixedly connected to the two base frames 100 respectively, so that the fixed roller 420 is placed horizontally above the two base frames 100 and is fixed relative to the position of the base frames 100. The protrusions 421 stably install the fixed roller 420 on the base frame 100, ensuring that the fixed roller 420 will not be displaced during the transmission of the steel belt 300. Its fixed positional relationship ensures the stability of the support for the steel belt 300 and provides a reliable reference for the pressure adjustment of the pressure roller 430.

[0041] like Figure 3 , Figure 5 and Figure 6As shown, specifically, the pressure roller 430 is rotatably connected to the bottom of the movable seat 431. The movable seat 431 provides a mounting carrier for the pressure roller 430, allowing it to change position as the movable seat 431 moves. An end plate 411 is fixed between the tops of the two support frames 410. The movable seat 431 is located below the end plate 411. Several guide posts 432 are fixed to the top of the movable seat 431. A stop plate 434 is provided above the movable seat 431. The guide posts 432 pass through the stop plate 434 and the end plate 411 sequentially, guiding the movement of the movable seat 431 and the stop plate 434. A spring 433 is sleeved on the outside of the guide posts 432 between the movable seat 431 and the stop plate 434. The spring 433, sleeved on the outside of the guide posts 432, can convert the pressure of the stop plate 434 into an elastic force on the movable seat 431. A push rod 440 is threadedly connected to the end plate 411. The bottom end of the push rod 440 abuts against the top surface of the push plate 434. The push rod 440 has a threaded rod structure, which allows it to change its relative position with the end plate 411 by rotation, thereby adjusting the pressure applied to the push plate 434. A lever 441 is provided at the top of the push rod 440. Several levers 442 are fixed on the outer circumferential surface of the lever 441. The levers 442 are the force-applying parts for rotating the lever 441. The levers 441 and 442 facilitate the operator in applying force, making the rotation of the push rod 440 easier.

[0042] like Figure 5 As shown, furthermore, the guide post 432 is slidably connected to the end plate 411 and to the abutment plate 434. This slidable connection prevents the movable seat 431 and the abutment plate 434 from shifting or jamming during movement, ensuring smooth motion. When the abutment rod 440 is tightened, it presses down on the abutment plate 434, causing the abutment plate 434 to compress the spring 433 downwards. This changes the elastic force of the spring 433, increasing the pressure of the pressure roller 430 on the steel strip 300, thus achieving fine adjustment of the tension of the steel strip 300.

[0043] It is worth noting that the pressure sensor 2132 involved in this utility model is a conventional technology and will not be described in detail here.

[0044] In this embodiment, the automatic steel strip tension measuring machine operates as follows: First, the operator holds the lever 442 and rotates the handle 441 according to the tension requirement of the steel strip 300, causing the abutment rod 440 to move downward on the end plate 411. The bottom end of the abutment rod 440 gradually presses down on the abutment plate 434. Then, guided by the guide post 432, the abutment plate 434 moves downward, compressing the spring 433 sleeved on the guide post 432. The spring 433 generates an upward elastic force due to deformation, and at the same time, it applies downward pressure to the movable seat 431. Next, under the pressure of the spring 433, the movable seat 431 moves downward along the guide post 432, driving the bottom abutment plate... Roller 430 moves closer to fixed roller 420, increasing the pressure on steel strip 300, thus changing the tension of steel strip 300. Finally, tension measuring mechanism 200 checks the adjusted tension of steel strip 300. If the check result does not meet expectations, the operator can continue to fine-tune lever 441 using lever 442 until the tension of steel strip 300 meets the requirements. If the tension is too high, reverse lever 440, which moves upward, reducing the pressure on the abutment plate 434, decreasing the compression of spring 433, weakening the pressure on movable seat 431, reducing the pressure of pressure roller 430 on steel strip 300, and correspondingly reducing the tension of steel strip 300.

[0045] 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.
