Description

Technical Field

[0001] This utility model belongs to the field of conveying device technology, and in particular relates to a material conveying device for a metal plate laser cutting machine. Background Technology

[0002] The material conveying device of a metal sheet laser cutting machine is a key component of an automated production line, and its design must take into account efficiency, precision, and safety.

[0003] In the existing technology, roller conveyors use motor-driven stainless steel rollers to transport metal sheets, which has the advantage of high speed. However, when the metal sheets being transported are relatively thin, the contact friction between the metal sheets and the rollers is limited. The metal sheets are prone to slipping during transport, resulting in uneven laser cutting and reduced cutting accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a material conveying device for a metal sheet laser cutting machine to solve the problems mentioned in the background art, including:

[0005] The first plate can be mounted on a metal plate laser cutting machine;

[0006] Several conveyor wheels are mounted on the first plate and can be driven to rotate;

[0007] Two second plates are mounted on the first plate and their positions can be changed, and the plurality of conveying wheels are disposed between the two second plates;

[0008] Several clamping components are mounted on the second plate, each clamping component including a column whose height can be changed;

[0009] Several auxiliary components are respectively mounted on the column. The auxiliary components include a wheel, which is disposed between two second plates and its height can be changed. The height of the wheel is greater than that of the conveyor wheel.

[0010] Preferably, the second plate has a first channel inside.

[0011] Preferably, the second plate body also has a second channel, and the column is slidably installed in the second channel.

[0012] Preferably, the clamping assembly further includes:

[0013] A first threaded rod is rotatably mounted in a second channel. The first threaded rod passes through the column and is threadedly connected to the column. The first threaded rod can be driven to rotate.

[0014] Preferably, the clamping assembly further includes:

[0015] The first driving component is capable of driving the first threaded rod to rotate.

[0016] Preferably, the first driving component is a motor, which is fixedly installed in the first channel. The output end of the motor passes through the second plate and extends into the second channel. The output end of the motor is fixed to the first threaded rod.

[0017] Preferably, the column has a groove.

[0018] Preferably, the auxiliary component further includes:

[0019] The second threaded rod passes through the cylinder and is threadedly connected to the cylinder.

[0020] The second driving component is capable of driving the second threaded rod to rotate;

[0021] The third plate is rotatably connected to the second threaded rod, and the third plate can slide along the groove.

[0022] The mounting base is fixedly connected to the third plate, and the rotating wheel is rotatably mounted inside the mounting base.

[0023] Preferably, the second driving component is a knob, which is fixed to the second threaded rod, and the knob can be rotated by an external force.

[0024] Preferably, the surface of the knob has several protrusions, which can increase the contact area between the knob and the outside world.

[0025] This application activates a first driving component to rotate a first threaded rod. The first threaded rod causes the column to slide along the second channel, thereby changing the height of the column.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0032] After metal sheets are conveyed by rollers and laser-cut, uneven cutting in some areas is occasionally observed, the cause of which is unknown. To address this problem, the inventors conducted in-depth research and discovered that slippage occurs when the metal sheets are thin and light. To solve this problem, this embodiment provides a material conveying device for a metal sheet laser cutting machine, such as... Figure 1 As shown, it includes: a first plate 100, several conveying wheels 200, two second plates 300, several pressing components 400, and several auxiliary components 500. The pressing components 400 move the rotating wheels 550 of the auxiliary components 500 and press the metal plates together, increasing friction and preventing slippage.

[0033] like Figure 1 As shown, the first plate 100 is a prior art material that can be installed on a metal plate laser cutting machine.

[0034] Continue as Figure 1 As shown, several conveyor wheels 200 are existing technology, which are mounted on the first plate 100 and can be driven to rotate. The metal plate is placed on top of the conveyor wheels 200 for conveying.

[0035] Continue as Figure 1 As shown, the two second plates 300 are existing technology, which are mounted on the first plate 100 and their positions can be changed (in order to limit the movement of metal plates of different sizes), and the plurality of conveying wheels 200 are arranged between the two second plates 300.

[0036] Continue as Figure 1 As shown, several clamping components 400 are mounted on the second plate 300, such as... Figure 2As shown, the clamping assembly 400 includes a column 430 (rectangular), the height of which can be changed. Specifically, a first channel 310 (square) is provided in the second plate 300, and a second channel 320 (rectangular) is also provided in the second plate 300. The column 430 is slidably installed in the second channel 320. The clamping assembly 400 also includes a first threaded rod 410 and a first driving member 420.

[0037] The first threaded rod 410 is existing technology. It is rotatably mounted in the second channel 320 (along the length of the second channel 320) via a bearing. The first threaded rod 410 passes through the column 430 and is threadedly connected to the column 430. The first threaded rod 410 can be driven to rotate. The first driving member 420 can drive the first threaded rod 410 to rotate. The first driving member 420 is a motor. The motor is fixedly mounted in the first channel 310. The output end of the motor passes through the second plate 300 and extends into the second channel 320. The output end of the motor is fixed to the first threaded rod 410. The motor is self-locking and can rotate in both directions.

[0038] When it is necessary to change the height of the column 430, the first driving component 420 is activated to drive the first threaded rod 410 to rotate. The first threaded rod 410 drives the column 430 to slide along the second channel 320, thereby changing the height of the column 430.

[0039] like Figure 1 As shown, several auxiliary components 500 are respectively mounted on the column 430, such as... Figure 3 As shown, the auxiliary component 500 includes a rotating wheel 550 (disc-shaped, rotating in the same direction as the conveyor wheel 200). The rotating wheel 550 is disposed between two second plates 300 and its height can be changed. The height of the rotating wheel 550 is greater than that of the conveyor wheel 200 (so as to press the metal plate against the top of the conveyor wheel 200). Specifically, a groove 431 (rectangular) is provided on the column 430. The auxiliary component 500 also includes: a second threaded rod 510, a second driving member 520, a third plate 530, and a mounting base 540.

[0040] The second threaded rod 510 is existing technology, which passes through the column 430 and is threadedly connected to the column 430. The second threaded rod 510 and the first threaded rod 410 are parallel. The second driving member 520 can drive the second threaded rod 510 to rotate. The second driving member 520 is a knob (disc-shaped). The knob is fixed to the second threaded rod 510 (top). The knob can be rotated by external force. The surface of the knob has several protrusions, which can increase the contact area between the knob and the outside world (increase the contact friction between the external force and the knob, and reduce the occurrence of slippage). The third plate 530 (similar to a U-shape) is rotatably connected to the second threaded rod 510 (bottom) through a bearing. The third plate 530 can slide along the groove 431. The mounting base 540 (square, with a groove at the bottom) is fixedly connected to the third plate 530 (bottom). The rotating wheel 550 is rotatably installed inside the mounting base 540.

[0041] Since the height adjustment range of the clamping assembly 400 to the rotating wheel 550 is limited, in order to increase the adjustment range of the device and further improve its applicability, in a further embodiment, the second threaded rod 510 is rotated by rotating the second driving member 520. The second threaded rod 510 moves along the column 430. At the same time, the second threaded rod 510 drives the third plate 530 to slide in the groove 431 and change its height. Simultaneously, the third plate 530 drives the mounting base 540 and the rotating wheel 550 to change their height. In conjunction with the height adjustment of the clamping assembly 400, this device can clamp metal plates of greater thickness, thus improving the applicability of the device.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
