Description

Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, and in particular to a plate feeding mechanism for a laser cutting production line. Background Technology

[0002] The plate feeding mechanism in a laser cutting production line refers to the mechanism used to feed plates into the laser cutting equipment.

[0003] A search revealed an automated production line for laser cutting of rolled materials using a gear hobbing mechanism, disclosed in patent application CN108393703A. This relates to rolled material processing, and more particularly to an automated production line for laser cutting of rolled materials using a gear hobbing mechanism. It features a simple structure, improved work efficiency, and cost savings. The production line sequentially includes a rolled material leveling device, a laser cutting device, and a material unloading and sorting device; the rolled material leveling device comprises a rolled material rack, a leveling mechanism, and a feeding mechanism arranged sequentially.

[0004] In contrast, the feeding mechanism in the patented design uses a lead screw drive, which is easily affected by dirt, causing jamming during transmission and affecting the continuity of material delivery. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing lead screws, which are easily affected by dirt, resulting in jamming during transmission and affecting the continuity of material conveying. This invention proposes a plate feeding mechanism for a laser cutting production line.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A plate feeding mechanism for a laser cutting production line includes a feeding body. Columns are fixedly connected to the four corners of the upper end of the feeding body. A ball bearing feeding plate is fixedly connected to the top of the four columns. A motor is fixedly installed on the inner wall of the feeding body. A lead screw is fixedly connected to the end of the output shaft of the motor. The other end of the lead screw is mounted on the inner wall of the feeding body via a bearing. A moving block is threadedly connected to the outer side of the middle section of the lead screw. A lubrication mechanism is provided inside the moving block. A support base is fixedly connected to the top of the moving block. A slip ring is fixedly connected to the middle of the upper end of the support base, and the slip ring is located outside the ball bearing feeding plate.

[0008] Furthermore, in a preferred configuration, an upper clamping block is fixedly connected to the left side of the slip ring, and a hydraulic cylinder is fixedly installed at the upper end of the support base, located on the left side of the slip ring. A lower clamping block is fixedly connected to the output end of the hydraulic cylinder. The lower clamping block passes through the ball feed plate and is slidably connected to it. The lower clamping block corresponds in position to the upper clamping block. By pushing the lower clamping block upward with the hydraulic cylinder, and then engaging with the upper clamping block, the sheet material moving on the ball feed plate can be clamped.

[0009] Furthermore, in a preferred configuration, the lubrication mechanism includes a sliding plate and an oil-retaining sponge slidably connected inside the moving block, with the sliding plate and the oil-retaining sponge in contact with each other. A sliding pin is fixedly connected to the bottom of the sliding plate, passing through the moving block and slidably connected to it. A spring is sleeved on the outer side of the pin, one end of which is fixedly connected to the sliding plate, and the other end is fixedly connected to the inner surface of the moving block. A pad is fixedly connected to the inner side of the feeder body, below the moving block, and this pad contacts the sliding pin. A protrusion is fixedly connected to the pad, its position corresponding to the sliding pin. This lubrication mechanism provides automatic lubrication between the moving block and the lead screw, preventing jamming between them.

[0010] Furthermore, in a preferred configuration, the movable block has an oil outlet hole inside, the position of which corresponds to the oil storage sponge. This oil outlet hole facilitates the discharge of lubricating oil from the oil storage sponge.

[0011] Furthermore, in a preferred configuration, a sealing ring is embedded in the side of the sliding plate, and the sealing ring contacts the inner surface of the moving block. The sealing ring enhances the seal between the sliding plate and the moving block.

[0012] Furthermore, in a preferred configuration, a rubber stopper is slidably connected to the right side of the movable block. This stopper, made of rubber, allows lubricant to be added to the oil reservoir sponge from its location after removal.

[0013] The beneficial effects of this utility model are as follows: By setting a lubrication mechanism between the lead screw and the moving block in the sheet feeding mechanism, an oil storage sponge is set inside the moving block, and a sliding plate with a sealing ring is set at the bottom of the oil storage sponge. A sliding pin with a spring is set at the bottom of the sliding plate, and the sliding pin passes through the moving block. In addition, a base plate with a protrusion is set inside the feeding body of the feeding mechanism. When the moving block and the lead screw slide relative to each other, the sliding pin is retracted by the reaction force of the protrusion, and the oil storage sponge is squeezed by the sliding plate. The lubricating oil in the oil storage sponge can be discharged through the oil outlet and lubricate the lead screw, thereby preventing jamming during the feeding process and ensuring the continuity of the sheet feeding process.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4 A plate feeding mechanism for a laser cutting production line includes a feeding body 1. Columns 13 are fixedly connected to the four corners of the upper end of the feeding body 1. A ball bearing feeding plate 14 is fixedly connected to the top of the four columns 13. A motor 2 is fixedly installed on the inner wall of the feeding body 1. A lead screw 3 is fixedly connected to the end of the output shaft of the motor 2. The other end of the lead screw 3 is mounted on the inner wall of the feeding body 1 via a bearing. A moving block 4 is threadedly connected to the outer side of the middle section of the lead screw 3. A support base 8 is fixedly connected to the top of the moving block 4. A slip ring 9 is fixedly connected to the middle of the upper end of the support base 8. The slip ring 9 is located on the outer side of the ball bearing feeding plate 14.

[0021] Reference Figure 1-4 An upper clamping block 10 is fixedly connected to the left side of the slip ring 9. A hydraulic cylinder 11 is fixedly installed at the upper end of the support base 8 and on the left side of the slip ring 9. A lower clamping block 12 is fixedly connected to the output end of the hydraulic cylinder 11. The lower clamping block 12 passes through the ball feed plate 14 and is slidably connected to the ball feed plate 14. The lower clamping block 12 corresponds to the position of the upper clamping block 10. By pushing the lower clamping block 12 upward by the hydraulic cylinder 11, and then cooperating with the upper clamping block 10, the plate material moving on the ball feed plate 14 can be clamped.

[0022] Reference Figure 4The movable block 4 is equipped with a lubrication mechanism 5, which provides automatic lubrication between the movable block 4 and the lead screw 3, preventing jamming. The lubrication mechanism 5 includes a sliding plate 51 and an oil storage sponge 52 slidably connected inside the movable block 4, with the sliding plate 51 and the oil storage sponge 52 in contact with each other. A sliding pin 53 is fixedly connected to the bottom of the sliding plate 51, passing through the movable block 4 and slidably connected to it. A spring 54 is sleeved on the outside of the pin of the sliding pin 53, with one end of the spring 54 fixedly connected to the sliding plate 51 and the other end fixedly connected to the inner surface of the movable block 4. A pad 6 is fixedly connected to the inside of the feeder body 1 and below the movable block 4, contacting the sliding pin 53. A protrusion 7 is fixedly connected to the pad 6, with the position of the protrusion 7 corresponding to that of the sliding pin 53. An oil outlet hole 55 is opened inside the movable block 4, with the position of the oil outlet hole 55 corresponding to that of the oil storage sponge 52. The oil outlet 55 facilitates the discharge of lubricating oil from the oil reservoir sponge 52. A sealing ring 57 is embedded in the side of the slide plate 51, and the sealing ring 57 contacts the inner surface of the moving block 4. The sealing ring 57 increases the sealing between the slide plate 51 and the moving block 4. A rubber stopper 56 is slidably connected to the right side of the moving block 4. After removing the rubber stopper 56, lubricating oil can be added to the oil reservoir sponge 52 through the stopper 56.

[0023] The specific implementation process of this utility model is as follows: In use, after the plate falls onto the ball feed plate 14 from the previous process, the lower clamping block 12 is pushed up by the oil cylinder 11. The lower clamping block 12, together with the upper clamping block 10, provides auxiliary fixation. Subsequently, the motor 2 drives the lead screw 3 to rotate, while the moving block 4 moves to the left along the axis of the lead screw 3 through the threaded movement between the moving block 4 and the lead screw 3. At the same time, the moving block 4 drives the support base 8 to move, and simultaneously drives the clamped plate to move and feed. During the movement of the moving block 4, the sliding pin 53 is retracted by the reaction force of the protrusion 7 on the pad 6, and then the oil storage sponge 52 is squeezed by the sliding plate 51. The lubricating oil in the oil storage sponge 52 can be discharged through the oil outlet 55, thereby lubricating the lead screw and preventing jamming during the feeding process, thus ensuring the continuity of the plate feeding process.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
