Description

Technical Field

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

[0002] When in use, the strip needs to be cut into small segments by a cutting device. The working process of the cutting device is as follows: the conveying roller rotates to drive the strip to move on the conveying platform. The strip moves through the position of the cutting knife, and then when the front end of the strip moves against the baffle, it means that the strip has moved in place. The horizontal distance between the cutting knife and the baffle is the length of the cut strip. The baffle serves to position the strip. In use, the baffle will reciprocate up and down driven by a cylinder. Before the strip is cut, the cylinder drives the baffle to move to the front side of the strip for positioning. After the strip is cut, the cylinder drives the baffle to move away from the front side of the strip to facilitate the continuous conveying of the cut strip. That is, each time the strip is cut, the cylinder needs to drive the baffle to move twice, and the service life of the cylinder will be affected by the number of actions. Therefore, a strip blocking method that can reduce the number of actions of the cylinder is needed. Content of the Utility Model

[0015] Such as Figure 1As shown in the figure, a strip cutting and blocking device according to this embodiment includes a conveying platform 1. A first conveying roller 2 and a cutting device 3 are arranged on the conveying platform 1. A blocking belt mechanism is arranged at the rear side of the cutting device 3. The blocking belt mechanism includes a moving frame 4 and a first driving device 5 for driving the moving frame 4 to move up and down. A through slot 6 for the strip to pass through is arranged on the moving frame 4. Upper baffle plates 7 and lower baffle plates 8 are symmetrically arranged on the upper and lower sides of the moving frame 4. The first driving device 5 is a cylinder. When the lower baffle plate 8 blocks the front side of the strip, after the cutting device 3 cuts the strip, the cylinder drives the moving frame 4 to move downward until the lower baffle plate 8 disengages from the front side of the strip. The first conveying roller 2 drives the strip to be conveyed, so that the cut strip passes through between the lower baffle plate 8 and the upper baffle plate 7. The width of the through slot 6 in the middle of the moving frame 4 is greater than the width of the strip. The moving frame 4 continues to move downward so that the upper baffle plate 7 blocks the front end of the strip, and the next strip positioning and cutting action is carried out. After cutting, the cylinder drives the moving frame 4 to move upward until the upper baffle plate 7 disengages from the front side of the strip. The first conveying roller 2 drives the strip to be conveyed, so that the cut strip passes through between the lower baffle plate 8 and the upper baffle plate 7. The moving frame 4 continues to move upward so that the lower baffle plate 8 blocks the front end of the strip, and the next strip positioning and cutting action is carried out, and so on in a cycle. After each cutting, the first driving device 5 only needs to perform a single-direction action once to realize the sending out of the strip and the positioning function of the next strip, reducing the action times of the cylinder and improving the service life.

[0016] Preferably, a second conveying roller 9 is arranged between the cutting device 3 and the blocking belt mechanism. After the strip is cut, it can be sent out through the second conveying roller 9 and pass through the moving frame 4 for forward conveying.

[0017] Preferably, a third conveying roller 10 is arranged at the rear side of the blocking belt mechanism. In this embodiment, the first conveying roller 2, the second conveying roller 9 and the third conveying roller 10 are all driven by motors (not shown in the figure). After the cut strip is sent out and passes through the moving frame 4, the strip can be continuously conveyed forward through the third conveying roller 10.

[0018] Preferably, the upper baffle plates 7 and the lower baffle plates 8 are movably installed on the moving frame 4. If the length of the cut strip is relatively long, the cylinder can first drive the upper baffle plates 7 and the lower baffle plates 8 to move into place, and only need to ensure that the front end of the strip passes through the through slot 6. If the cylinder drives the moving frame 4 to move downward, the movable end of the upper baffle plate 7 can abut against the upper surface of the strip until the strip is completely sent out, and then the upper baffle plate 7 resets and blocks the front end of the uncut strip. Similarly, if the cylinder drives the moving frame 4 to move upward, the movable end of the lower baffle plate 8 abuts against the lower surface of the strip until the strip is completely sent out, and then the lower baffle plate 8 resets and blocks the front end of the uncut strip.

[0019] Preferably, rotating shafts 11 are rotatably arranged at the movable ends of the upper baffle plates 7 and the lower baffle plates 8, which can avoid scraping between the upper baffle plates 7 and the lower baffle plates 8 and the strip.

[0020] Preferably, the upper baffle plate 7 and the lower baffle plate 8 are hinged to the moving frame 4. The upper baffle plate 7 and the lower baffle plate 8 are L-shaped. An upper positioning plate 12 is arranged on the moving frame 4 to cooperate with the upper baffle plate 7, and a lower positioning plate 13 is arranged on the moving frame 4 to cooperate with the lower baffle plate 8. A first elastic member 14 tending to force the lower baffle plate 8 to press on the lower positioning plate 13 is arranged on the moving frame 4. When the upper baffle plate 7 is placed on the upper positioning plate 12, the surface of the upper baffle plate 7 cooperating with the strip steel is in a vertical state. When the lower baffle plate 8 is placed on the lower positioning plate 13, the surface of the lower baffle plate 8 cooperating with the strip steel is in a vertical state. The first elastic member 14 is a spring, and the lower baffle plate 8 can be reset through the first elastic member 14. After the strip steel is cut, if the lower baffle plate 8 blocks the front end of the strip steel at this time, the air cylinder drives the moving frame 4 to move downward. After the lower baffle plate 8 separates from the strip steel, the second conveying device drives the cut strip steel to be sent out. The front end of the strip steel passes through the through slot 6, and the moving frame 4 can continue to move to a height where the upper baffle plate 7 can block the strip steel. At this time, the movable end of the upper baffle plate 7 will abut against the upper surface of the strip steel, and the upper baffle plate 7 will swing until the strip steel completely passes through the through slot 6. Then the upper baffle plate 7 resets downward, and the side surface of the upper baffle plate 7 returns to vertical, waiting for the positioning function for the subsequent strip steel. The process of cutting and sending out the next strip steel is that the air cylinder drives the moving frame 4 to move upward. Thus, the upper baffle plate 7 and the lower baffle plate 8 can alternately position the strip steel.

[0021] Preferably, a second elastic member 15 tending to force the upper baffle plate 7 to press on the upper positioning plate 12 is arranged on the moving frame 4. The second elastic member 15 is a spring, and the upper baffle plate 7 can be reset through the second elastic member 15.

Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention so as to design various embodiments with various modifications suitable for specific purposes.
