Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to an automatic blank cutting device. Background Art

[0002] When a blank rod is being processed and produced, its length, diameter and other dimensions often need to be determined according to specific design requirements, and it needs to be cut into the required length first. Currently, there are devices on the market that automatically cut blank rods. The blank rods are transported to the cutting position on the cutting equipment and then cut. Currently, when cutting blank rods, most of them are cut one by one, which makes the cutting efficiency slow. Therefore, in order to effectively improve the cutting efficiency, multiple blank rods are transported at the same time during transportation, so that multiple blank rods can be cut at the same time during cutting. However, the blank rods are transported by roller conveying equipment. The rollers on the conveying equipment drive the blank rods to move through the friction between the rollers and the blank rods. When the rollers drive multiple blank rods to move, some blank rods may slip, resulting in uneven ends of the blank rods moved to the cutting position, resulting in multiple blank rods being cut to different lengths. Utility Model Content

[0003] The purpose of the present utility model is to solve the problem mentioned in the above-mentioned background technology that multiple blank rods may slip when moving through roller conveying equipment, resulting in uneven ends of the blank rods moved to the cutting position, resulting in multiple blank rods being cut to different lengths.

The equipment box 1 is also provided with a cutting device 2 for rotating to cut the blank rod and a conveying plate 3 for guiding the cut blank rod to drop. The conveying plate 3 includes a blanking plate 1 and a blanking plate 2 32. The blanking plate 1 31 and the blanking plate 2 32 are connected. The ends are pressed together and fixedly installed in the equipment box 1. Blanking plate 1 31 and blanking plate 2 32 are used to guide the blanking of the blank rod after cutting. The driving member 5 is arranged in the equipment box 1 and is connected to the cutting device 2. The driving member 5 is provided with a baffle 4 that makes the front ends of several blank rods flush. The adjusting member 511 is provided on the driving member 5 to adjust the distance between the baffle 4 and the cutting device 2 to cut blank rods of different lengths.

A connecting shaft is provided at the turning point on the cutting machine. The rotating plate 51 on the driving member 5 is connected to the connecting shaft at one end away from the pressure rod 52, so that the cutting machine can drive the rotating plate 51 to rotate together when it rotates, thereby driving the driving member 5 to operate.

[0031] Furthermore, a movable hole 1 532 is provided on the movable plate 1 53, and the pressure rod 52 is movable in the movable hole 1 532. Both ends of the rotating plate 2 57 are provided with movable holes 2 571. A connecting rod 1 56 is provided at one end connecting the pressure rod 52 and the rotating plate 2 57. A connecting rod 2 59 is provided on the movable plate 2 58. The connecting rod 1 56 and the connecting rod 2 59 are respectively movable in two movable holes 2 571.

[0032] It should be noted that the length of the movable hole 2 571 on the rotating plate 2 57 near the end of the movable plate 2 58 is greater than the length of the movable hole 2 571 near the pressure rod 52. The length of the movable hole 2 571 near the side of the pressure rod 52 is longer, ensuring that the movable plate 2 58 can move upward with a larger stroke. A connecting end 531 is provided on the movable plate 1 53, and a through hole is opened on the connecting end 531. A limiting rod 1 54 is provided in the through hole. The limiting rod 1 54 is fixed in the equipment box 1. When the movable plate 1 53 moves, the limiting rod 1 54 can limit the movement of the movable plate 1 53 through the connecting end 531, ensuring that the movable plate 1 53 can stably move up and down linearly.

[0033] The driving member 5 also includes a positioning plate 512, which is provided with a guide hole 513. The upper part of the movable plate 2 58 is movable in the guide hole 513. The positioning plate 512 is fixed in the equipment box 1, and the movable plate 2 58 can be limited by the guide hole 513 to ensure that the movable plate 2 58 can stably move up and down linearly. A rotating pin 514 is provided on the rotating plate 2 57, and the rotating pin 514 is provided on the side close to the pressure plate 55. The rotating pin 514 is rotatably provided on the positioning plate 512. When the rotating plate 2 57 rotates, it rotates with the rotating pin 514 as the rotating point. The rotating pin 514 is provided on the side close to the pressure plate 55, so that the rotating plate 2 57 can drive the movable plate 2 58 to move upward for a longer stroke when rotating, ensuring that the baffle 4 can be fully moved away and will not block the falling of the blank rod after cutting.

[0034] It should be added that the adjusting member 511 includes a ball screw 5111, and the ball screw 5111 is provided with a ball nut that cooperates with it. One end of the ball nut is rotatably connected to the mounting plate 510, and one end of the ball screw 5111 is fixedly connected to the movable plate 2 58. The current position of the baffle 4 can be moved and adjusted through the adjusting member 511, so that the baffle 4 can be suitable for use in cutting raw rods of different lengths within a certain range. The adjusting member 511 also includes a limiting rod 2 5112, and a limiting hole is provided on the mounting plate 510. The limiting rod 2 5112 is movable in the limiting hole. The limiting rod 2 5112 is fixedly connected to the movable plate 2 58 near one end of the movable plate 2 58, wherein the limiting rod can limit the baffle 4 so that the baffle 4 can only move linearly, ensuring that the ball nut can drive the baffle 4 to stably move and adjust its position.

[0035] Among them, a rotating block with a protrusion is provided on the outer side of the end of the ball nut away from the mounting plate 510. The protrusion on the rotating block can provide a better gripping point, so that the user can hold the rotating block more stably when rotating.

[0036] When in use, the roller conveyor conveys multiple blank rods and conveys multiple blank rods that need to be cut to the position of the cutting device 2. The ends of the multiple blank rods will first abut against the baffle 4 and cannot move anymore. As the roller conveyor continues to move the blank rods toward the cutting device 2, the ends of the multiple blank rods can be flush against the baffle 4, which can ensure that the lengths of the multiple blank rods cut subsequently are consistent. Then the limiting mechanism 6 is started to abut and fix the multiple blank rods to ensure stability during cutting. Then the cutting blade on the cutting device 2 rotates and rotates toward the blank rod. When the cutting device 2 rotates to cut the blank rod, it drives the rotating plate 1 51 to rotate together, and the rotating blanking plate 1 31 drives the pressure rod 52 to rotate downward, and the pressure rod 52 moves the moving plate 1 53 When the cutting device 2 is pressed downward, the pressure plate 55 is driven to move downward, and the pressure plate 55 pulls the rotating blanking plate 2 32 connected to the end thereof to rotate downward, and the rotating blanking plate 2 32 rotates with the rotating pin 514 as the center of the circle. During the rotation, the rotating plate 2 57 and the end connected to the moving plate 2 58 are rotated upward, thereby driving the moving plate 2 58 to move upward, and the moving plate 2 58 drives the blanking plate 1 31 to move upward together through the mounting plate 510, so that when the cutting device 2 cuts off a plurality of blank rods, the cut blank rods can fall along the conveying plate 3, and the removal of the baffle 4 will not affect the blanking of the blank rods. The baffle 4 provided in the present invention can make the ends of the plurality of blank rods flush, thereby ensuring that the cutting positions of the plurality of blank rods are the same, and the cut lengths of the plurality of blank rods are consistent, thereby ensuring the cutting quality.

[0037] By rotating the rotating block, the rotating block can drive the ball nut to rotate. The ball nut can move linearly during rotation through the cooperation relationship with the ball screw 5111, thereby driving the baffle 4 to move and adjusting the current position of the baffle 4, so that the baffle 4 can be suitable for use in cutting raw rods of different lengths within a certain range.
