[0035] Reference below Figure 1-Figure 5 A steel strip cutting production line is described in detail with a specific embodiment. It is worth noting that the following description is merely an illustrative description and is not intended to limit the utility model.

[0036] like Figure 1-Figure 5 As shown, a steel strip cutting production line includes:

[0037] The unwinding assembly 100 is used to place the steel strip coil and unwind the steel strip of the steel strip coil;

[0038] The surface smoothing assembly 110 is capable of receiving the steel strip from the unwinding assembly 100 and smoothing the steel strip;

[0039] The cutting assembly 120 includes two movable bases 1201, between which the steel strip is transferred. The two movable bases 1201 can move toward or away from each other to accommodate steel strips of different widths. Each movable base 1201 is provided with a sensor 1202 and a cutter 1203 located in the same straight line. The sensor 1202 senses irregular protrusions on the edge of the steel strip and cooperates with the cutter 1203 to drive the cutter 1203 to cut the sensed irregular protrusions.

[0040] The cleaning and drying assembly 170 is capable of receiving the steel strip from the surface leveling assembly 110 and cooperating with the sensor 1202 and the cutter 1203 to spray water on the cut portion of the steel strip for cleaning and drying.

[0041] The winding assembly 180 can receive the steel strip from the cleaning and drying assembly 170 and rewind it into a roll.

[0042] Specifically, the unwinding assembly 100 is responsible for placing the steel strip coil and unwinding the steel strip to provide continuous steel strip material for subsequent processing of the production line; the surface smoothing assembly 110 smoothes the steel strip from the unwinding assembly 100 by adjusting the gap and pressure between the roller groups to eliminate the unevenness and ripples on its surface; when the steel strip is stretched and cut, the steel strip is transmitted between the two moving seats 1201, and the distance between the two moving seats 1201 is the width of the steel strip; the moving seats 1201 can be moved closer or farther away from each other to adjust the spacing. To adapt to steel strips of different widths; the sensor 1202 on the movable seat 1201 senses the irregular convexities on the edge of the steel strip, and cooperates with the cutter 1203 to drive the cutter 1203 to accurately cut the sensed irregular convexities; the cleaning and drying component 170 sprays water to clean the cut part of the steel strip to remove impurities generated by the cutting, and then dries the steel strip by hot air circulation to ensure that the steel strip is dry and clean; the steel strip processed by the cleaning and drying component 170 is received and re-reeled into a roll for easy storage and transportation.

[0043] Since the sensor 1202 and the cutter 1203 are located on the same straight line and the straight line is horizontal to the transmission track of the steel strip; the sensor 1202 has a matching end, which is located below the steel strip. The sensor 1202 sends a signal to the matching end and then returns from the matching end; the sensor 1202 calculates the change in the round-trip time of the signal to determine whether the edge of the steel strip has an irregular convex part; for example, if the steel strip has an irregular convex part, it will block the signal, and the signal will return after contacting the irregular convex part, shortening the round-trip time of the signal, then it is determined that the edge of the steel strip has an irregular convex part, and sends a signal to the cutter 1203. The operation signal is sent, and the cutter 1203 operates to cut the irregular convex part; when the irregular convex part passes through the sensing position of the sensor 1202 and the signal reciprocating time of the sensor 1202 returns to its original state, a stop operation signal is sent to the cutter 1203; in addition, an interval time value can be set between the recovery of the signal reciprocating time of the sensor 1202 and the occurrence of the stop operation signal, so that after the signal reciprocating time of the sensor 1202 is recovered, the stop operation signal is sent to the cutter 1203 after the interval time value has passed, to ensure that the cutter 1203 can cut the irregular convex part before stopping.

[0044] The present invention achieves continuous, automated processing of steel strips through the coordinated operation of the unwinding assembly 100, surface smoothing assembly 110, cutting assembly 120, cleaning and drying assembly 170, and rewinding assembly 180, thereby improving production efficiency. The sensor 1202 of the cutting assembly 120 accurately senses irregularities on the edge of the steel strip and cooperates with the cutter 1203 to precisely cut it, ensuring cutting quality. Furthermore, the cutter 1203 starts and stops operating based on the sensing state of the sensor 1202, eliminating the need for constant operation and saving costs. This also avoids wear and tear on portions of the steel strip's edge that lack irregularities upon contact with the operating cutter 1203, thereby achieving precise cutting of irregularities on the steel strip's edge.

[0045] In some specific embodiments of the present invention, the cutting assembly 120 includes a mounting track 130, on which a movable base 1201 slides. The mounting track 130 is provided with a stopper that restricts the sliding movement of the movable base 1201. Specifically, the movable base 1201 slides on the mounting track 130 and can be adjusted according to the width of the steel strip, ensuring that the steel strip can be smoothly transported and passed through the cutting area. The stopper fixes the position of the movable base 1201, preventing it from moving unnecessarily during operation, thereby ensuring cutting accuracy and stability.

[0046] By flexibly adjusting the position of the movable base 1201, the cutting assembly 120 can adapt to steel strips of varying widths, ensuring that the cutter 1203 can accurately cut irregular protrusions on the steel strip's edge. The provision of a stopper ensures the stability of the movable base 1201, reducing wear and maintenance costs associated with its movement. Furthermore, the cutter 1203 activates only when the sensor 1202 detects an irregular protrusion, avoiding unnecessary energy consumption and wear on the cutter 1203, further saving costs.

[0047] In some specific embodiments of the present invention, the limiter includes a connecting seat connected to the movable seat 1201, the connecting seat has a mounting hole, a threaded shaft is arranged in the mounting hole, and the mounting rail 130 has several limiting holes arranged at intervals along the length direction, and the threaded shaft can be inserted into the limiting hole for threaded engagement.

[0048] Specifically, when the position of the movable seat 1201 needs to be adjusted, the threaded shaft is rotated to move it out of the limiting hole, and the movable seat 1201 is slid to the desired position on the mounting rail 130. When the movable seat 1201 reaches the predetermined position, the threaded shaft is rotated to insert it into the limiting hole for threaded engagement to fix the movable seat 1201 and prevent it from sliding.

[0049] By setting the limiter, the position of the movable seat 1201 can be accurately adjusted to ensure that the steel strip can pass through the cutting assembly 120 stably during the transmission process; the threaded matching structure of the limiter is firm and reliable, which can prevent the movable seat 1201 from accidentally sliding during the transmission of the steel strip, thereby improving the stability and safety of the production line.

[0050] In some specific embodiments of the present invention, each movable base 1201 is provided with a mounting plate 140. Multiple guide wheels 150 are sequentially arranged along the length of the mounting plate 140. Each guide wheel 150 has guide grooves 1501 defined along its outer periphery. The steel belt passes through the guide grooves 1501 on the multiple guide wheels 150 to guide the belt during transport. The guide wheels 150 on each side of the mounting plate 140 engage the edges of the steel belt, respectively. By inserting the edges of the steel belt into the guide grooves 1501 of the guide wheels 150, the steel belt is guided and positioned, effectively reducing the amount of wobbling during transport and preventing it from straying from the transport path.

[0051] There are four guide wheels 150 on a single mounting plate 140. In other embodiments, the number of guide wheels 150 can be adjusted according to demand, and can be 2, 3, 5, 6, 7 or 8.

[0052] The arrangement of the guide wheel 150 and the guide groove 1501 not only provides a stable transmission path, but also reduces the friction and resistance of the steel belt during the transmission process.

[0053] In other embodiments, the shape and size of the guide groove 1501 can be optimized according to needs to accommodate steel strips of different widths and thicknesses.

[0054] In some specific embodiments of the present invention, the cutting assembly 120 further includes at least two fixed rollers 160 , and the two fixed rollers 160 are rotatably distributed on both sides of the movable base 1201 .

[0055] Specifically, two fixed rollers 160 are rotatably located on either side of the movable base 1201 and are able to rotate freely. When the steel strip passes between the two movable bases 1201, the fixed rollers 160 help maintain the stability and direction of the steel strip. By rotating, they reduce friction and resistance during the steel strip's transmission. This helps stabilize the steel strip during operation of the cutter 1203, ensuring that the cutter 1203 effectively cuts the steel strip.

[0056] In some specific embodiments of the present invention, the cleaning and drying component 170 includes a cleaning spray gun 1701 and a drying box 1702. The cleaning spray gun 1701 is close to the middle position of the two movable seats 1201 and faces the cutting station of the cutter 1203. The steel strip passes through the drying box 1702, and the drying box 1702 dries the steel strip through hot air circulation.

[0057] Specifically, the cleaning spray gun 1701 is positioned near the center of the two movable seats 1201 and faces the cutting station of the cutter 1203. After the steel strip passes through the cutter 1203 and is cut, the cleaning spray gun 1701 sprays water to clean the cut area of ​​the steel strip, removing impurities and debris generated by the cutting. Due to the positioning of the cleaning spray gun 1701, its spray direction is from the inside to the outside. During the spraying, impurities and debris generated by the cutting are flushed outward, preventing them from moving along the water flow toward the center of the steel strip and becoming lodged there. At the same time, the cleaning spray gun 1701 sprays water directly toward the cutting station of the cutter 1203, which can have a certain cooling effect on the cutter 1203.

[0058] In addition, the steel strip passes through the drying box 1702, and the drying box 1702 dries the steel strip by circulating hot air. The hot air circulation can ensure that the moisture on the steel strip evaporates quickly, so that the steel strip remains dry and clean.

[0059] In some specific embodiments of the present invention, a baffle is provided between the cutter 1203 and the sensor 1202 .

[0060] Specifically, a baffle is positioned between the cutter 1203 and the sensor 1202, primarily to prevent sparks, debris, and other flying debris generated during the cutting process from directly contacting the sensor 1202, thereby effectively protecting the sensor 1202 from damage. When the sensor 1202 detects an irregular protrusion on the edge of the steel strip and drives the cutter 1203 to cut, the baffle acts as a barrier, ensuring that flying debris does not interfere with the normal operation of the sensor 1202 and avoid misjudgment. Furthermore, when the cleaning gun 1701 sprays water to clean the cutting station, the baffle prevents splashing, ensuring the normal operation of the sensor 1202.

[0061] In some specific embodiments of the present invention, the surface leveling assembly 110 includes a plurality of leveling roller groups 1101 , which are alternately arranged up and down. The steel strip is leveled by adjusting the gap and pressure between the plurality of leveling roller groups 1101 .

[0062] Specifically, there are three sets of leveling rollers 1101, arranged alternately in an upper and lower arrangement. By precisely adjusting the gap and pressure between these leveling rollers 1101, the passing steel strip can be effectively leveled. Specifically, the rolling action of the leveling rollers 1101 and the appropriate adjustment of the distance between them tighten the steel strip, helping to eliminate surface irregularities and ripples, thereby ensuring the flatness and quality of the steel strip.

[0063] In some specific embodiments of the present invention, the sensor 1202 is an infrared sensor or a laser sensor. Whether using an infrared sensor or a laser sensor, the irregular convex portion of the edge of the steel strip can be accurately detected to provide accurate positioning information for subsequent cutting operations.

[0064] Infrared sensors detect irregular convexities on the edge of a steel strip by emitting infrared light and receiving the reflected or transmitted signals. When irregular convexities exist on the edge of a steel strip, they block the propagation path of the infrared light, thereby changing the sensor's signal state.

[0065] Laser sensors use a laser beam as a detection method, detecting irregularities by measuring the time difference or angle change between the laser beam's emission and its reflection from the strip edge. When the laser beam encounters an irregularity, its reflection path changes, and the sensor uses this information to determine the condition of the strip edge.

[0066] In some specific embodiments of the present invention, a PLC controller is included to control the overall coordinated operation of the unwinding assembly 100, the surface smoothing assembly 110, the cutting assembly 120, the cleaning and drying assembly 170 and the winding assembly 180.

[0067] Specifically, the PLC controller, or programmable logic controller, receives input signals from various components, including the unwinding assembly 100, surface smoothing assembly 110, cutting assembly 120, cleaning and drying assembly 170, and winding assembly 180, and processes them according to pre-set program logic. After processing, the PLC controller outputs control signals to drive the operation of each component. It contains components such as a central processing unit (CPU), memory, and input / output (I / O) modules. By executing the programs stored in the memory, it achieves automated control of the entire steel strip stretching and cutting production line.

[0068] The PLC controller coordinates the overall operation of the steel strip cutting production line, ensuring precise coordination between all components. Using pre-set programs, the PLC controller flexibly adjusts operating parameters of each component, such as cutting speed and leveling pressure, to meet specific production requirements, thereby ensuring flexibility and controllability in the production process. The PLC controller also features fault diagnosis and alarm functions, enabling real-time monitoring of the production line's operating status. Any abnormalities detected can be promptly addressed to ensure safe and stable operation of the production line.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
