Description

Technical Field

[0001] The utility model relates to the technical field of strip cutting, in particular to a strip cutting and blanking device. Background Technique

[0002] A strip is a narrow and long steel plate, often also called a steel strip, and its length varies according to the size of each roll. When processing strips, a cutting device is required for cutting. The strip cutting and blanking device mainly consists of a frame, a guide seat, a conveying mechanism, a cutting mechanism, a collection box and other structures. When the strip cutting and blanking device works, first start the conveying mechanism, adjust the gap between the upper roller and the lower roller through the lifting of the cylinder, clamp the strip and convey it into the guide hole. During the conveying process, the motor drives the lower roller to rotate, driving the strip forward. When the strip reaches the cutting position, the cutting mechanism is started. The cylinder drives the lifting plate and the cutting knife to descend, and the cutting knife cuts the strip.

[0003] For example, the Chinese patent "A Strip Cutting and Blanking Device" with the publication number CN216326840U includes a frame, a guide seat, a conveying mechanism, a cutting mechanism, a blanking plate and a collection box. The guide seat is installed on the top of the frame, and a guide hole is provided inside the guide seat; the conveying mechanism for conveying the strip is provided at one end of the guide hole on the top of the frame, and the cutting mechanism for cutting the strip is provided at the other end of the guide hole on the top of the frame. The blanking plate is inclined at one end of the frame close to the cutting mechanism, and a feeding port is provided on the outer wall of the collection box, and the lower end of the blanking plate is arranged at the bottom of the feeding port.

[0004] Although the above-mentioned prior art can realize the cutting of strips, in actual use, on the one hand, the blanking of the cut strips is not convenient enough. The cut strips directly fall into the collection box, and the strips collide with the inner wall of the collection box, resulting in damage to the wooden collection box due to the collision, thus affecting the packaging of the strips. On the other hand, the feeding of the cut strips is not flexible enough. After the strip cutting is completed, one section falls into the collection box, and the other section is on one side of the cutter head. At this time, the operator needs to push the strip to move, resulting in the need for the operator's assistance during feeding, thus increasing the operator's operation amount. Therefore, it does not meet the existing requirements, and for this reason, we propose a strip cutting and blanking device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a strip cutting and blanking device to solve the problems of inconvenient blanking of the cut strips and inflexible feeding of the cut strips proposed in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A strip cutting and blanking device, including support rods. There are four support rods, and a workbench is fixedly arranged at the upper ends of the support rods. A conveying groove is arranged at the middle position inside the workbench. The conveying groove is of an open structure. Three rotating rods are arranged on both sides inside the conveying groove. There is a certain distance between the rotating rods on both sides near the center position of the conveying groove. Belt rollers are fixedly arranged on the outer part of the rotating rods, and a conveyor belt is sleeved on the outer part of the belt rollers. A collection box is arranged on one side of the workbench. A groove is arranged inside one side wall of the collection box, and the groove corresponds to the position of the conveyor belt. A fixing frame is fixedly arranged at the lower end of the collection box.

[0007] Preferably, first motors are fixedly arranged on both sides at the rear end of the workbench. The output shafts of the first motors extend into the inside of the conveying groove and are fixedly connected with the rotating rods.

[0008] Preferably, a first mounting frame is fixedly arranged at the middle position on the upper end of the workbench. First hydraulic telescopic devices are fixedly arranged at the front and rear ends on the upper end of the cross plate of the first mounting frame. The telescopic ends of the first hydraulic telescopic devices extend below the cross plate of the first mounting frame. A blade is fixedly arranged at the lower end of the telescopic ends of the first hydraulic telescopic devices.

[0009] Preferably, mounting ear plates are arranged at the front and rear ends inside the conveying groove below the blade. Second motors are fixedly arranged at the lower ends of the mounting ear plates. The output shafts of the second motors extend into the inside of the mounting ear plates and are rotatably connected with the inner walls of the mounting ear plates. Rollers are fixedly arranged on the outer parts of the output shafts of the second motors located inside the mounting ear plates.

[0010] Preferably, mounting seats are fixedly arranged at the upper ends of the mounting ear plates. Second hydraulic telescopic devices are fixedly arranged at the front and rear ends outside the first mounting frame. The telescopic ends of the second hydraulic telescopic devices extend below the cross plate of the first mounting frame and are fixedly connected with the mounting seats.

[0011] Preferably, telescopic cavities are arranged inside the workbench on both sides of the first mounting frame. Third hydraulic telescopic devices are fixedly arranged inside the telescopic cavities. The upper ends of the telescopic ends of the third hydraulic telescopic devices are fixedly provided with second mounting frames, and the second mounting frames extend above the workbench.

[0012] Preferably, a rubber pad is arranged below the cross plate of the second mounting frame, and the rubber pad is connected to the cross plate of the second mounting frame by glue.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The utility model can make the strip steel more stable during blanking through the conveyor belt and the collection box. Before the cutting operation, the first motors on both sides are turned on, and the output shafts of the first motors drive the rotating rods and the belt rollers to rotate together. At this time, the belt rollers drive the conveyor belt to move. Then, the strip steel is placed on the conveyor belt until the cutting operation of the strip steel is completed. At this time, the first motors are turned on again, and the output shafts of the first motors drive the conveyor belt to move. At this time, the cut section of the strip steel moves on the conveyor belt until the strip steel is moved to the opening of the collection box. At this time, under the action of the conveyor belt, the strip steel enters the interior of the collection box, making the strip steel fall into the interior of the collection box more smoothly, thereby reducing the situation that the collection box is damaged due to the collision of the strip steel.

[0015] 2. The utility model can move the cut strip steel through the rollers and the mounting ear plates. When the strip steel is cut once, the first motors on both sides are turned on first. The output shafts of the first motors drive the belt rollers and the conveyor belt to rotate. At this time, the strip steel located on the conveyor belt moves. One section of the strip steel moves into the collection box, and the other section of the strip steel moves to one side of the blade. At this time, the second hydraulic telescopic device is turned on, and the telescopic end of the second hydraulic telescopic device extends and drives the mounting ear plate to move towards the middle position of the workbench until the mounting ear plate moves to a suitable position. At this time, the rollers on the mounting ear plate contact the strip steel and the second motor is turned on. The output shaft of the second motor drives the rollers to rotate, and the strip steel is moved to another conveyor belt through the friction between the strip steel and the rollers, simplifying the feeding step after the strip steel is cut, thereby improving the cutting efficiency of the strip steel.

[0016] 3. The utility model can fix the strip steel during cutting through the third hydraulic telescopic device and the second mounting frame. Before the strip steel is cut, the strip steel has moved to the cutting position. At this time, the third hydraulic telescopic device is turned on, and the telescopic end of the third hydraulic telescopic device contracts. The contraction of the telescopic end of the third hydraulic telescopic device drives the second mounting frame to move downward until the second mounting frame moves to a suitable position. At this time, the rubber pad at the lower end of the cross plate of the second mounting frame contacts and presses the upper end surface of the strip steel. At this time, the strip steel is cut by the blade, avoiding the situation that the strip steel warps during the cutting operation, thereby improving the cutting quality of the strip steel.
