Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically to a plate feeding device for a carving machine. Background Technology

[0002] A panel engraving machine is a mechanical device used for cutting, engraving, drilling, and other processing of various panels. It combines computer technology, CNC technology, and mechanical technology to quickly and accurately complete the engraving and processing of various panels. It is mainly used in fields such as architectural decoration, advertising, and engineering panel processing.

[0003] Traditional panel engraving machines lack a feeding device, requiring operators to manually load the panels onto the machine's worktable. With technological advancements, most panel engraving machines are now equipped with feeding devices. These devices typically include a lifting mechanism, a pushing mechanism, and a conveying mechanism. In operation, the panels to be engraved are stacked on the lifting mechanism. The operator simply operates a button to raise the panels to their designated positions, and then the pushing mechanism sends the top panel onto the conveying mechanism. This simple operation significantly reduces manpower. However, these feeding devices still have the following drawbacks: 1. The lifting distance of the lifting mechanism is difficult to control, easily resulting in insufficient or excessive lifting, leading to panel jamming or the pushing mechanism accidentally pushing two panels at once. 2. They cannot limit the movement of stacked panels. When many panels are stacked, they are prone to tilting, and with high friction between panels, the bottom panel may shift towards the conveying mechanism as the pushing mechanism moves. Utility Model Content

[0004] The purpose of this invention is to overcome the technical defects of existing plate feeding devices, such as the inconvenience in controlling the lifting distance of the plate, which leads to the plate getting stuck or pushing two plates at once without being able to limit the plate position, resulting in the plate being skewed. This invention provides a plate feeding device for engraving machines.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a plate feeding device for a carving machine, comprising a plate lifting mechanism, a plate pushing mechanism, and a plate conveyor. The plate pushing mechanism and the plate conveyor are located at opposite ends of the plate lifting mechanism. The plate lifting mechanism includes a base, a lifting support platform, a limiting plate, and a baffle. Two limiting plates are provided and are slidably arranged on the left and right sides of the base. The lifting support platform is located inside the base and between the two limiting plates. The baffle is fixed to the base near the end of the plate conveyor. The top of the limiting plate is provided with a groove, inside which a sliding pressure block and a support block are fitted. Limit switch one and limit switch two are respectively provided at the bottom of the groove and on the bottom surface of the support block. Limit switch one is used to control the lifting support platform to start, and limit switch two is used to control the lifting support platform to stop. The sliding pressure block is located between limit switch one and limit switch two, and the sliding pressure block presses on the topmost plate. The top of the limiting plate is provided with an adjustment mechanism for adjusting the position of the support block.

[0006] Furthermore, the base is provided with an opening groove, in which a bidirectional threaded rod is rotatably provided. The bottom end of the limiting plate is located in the opening groove, and it is provided with a threaded through hole that mates with the bidirectional threaded rod.

[0007] Furthermore, the top of the baffle is flush with the top surface of the plate conveyor.

[0008] Furthermore, the bottom of the sliding pressure block is provided with rollers, which contact the plate.

[0009] Furthermore, the top of the support block is provided with an adjusting screw, and the limiting plate is provided with a corresponding threaded through hole two. The adjusting screw passes through the threaded through hole two and extends to the top of the limiting plate. The top of the adjusting screw is provided with a rotating handle.

[0010] Furthermore, the bottom of the chute is flush with the top surface of the plate conveyor, and a scale is provided on one side of the chute.

[0011] Furthermore, the lifting support platform is a scissor lift.

[0012] The beneficial effects of this utility model are as follows: The plate feeding device of this utility model limits the plate to be carved by two limiting plates and one baffle, thereby preventing the plate from tilting; the lifting support platform can be started and stopped by sliding pressure block lifting contact limit switch one and limit switch two, without manual control, and the control is precise. By adjusting the height of the support block, it can adapt to the feeding of plates of different thicknesses. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0022] Embodiments of this utility model: such as Figure 1 , 2As shown in Figures 4 and 5, a plate feeding device for a carving machine includes a plate lifting mechanism 1, a plate pushing mechanism 2, and a plate conveyor 3. The plate pushing mechanism 2 and the plate conveyor 3 are located at opposite ends of the plate lifting mechanism 1. The plate lifting mechanism 1 includes a base 4, a lifting support platform 5, a limiting plate 6, and a baffle 7. Two limiting plates 6 are provided and are slidably and openably disposed on the left and right sides of the base 4. The lifting support platform 5 is disposed within the base 4 and located between the two limiting plates 6. The baffle 7 is fixed to the base 4. Near one end of the plate conveyor 3; the top of the limiting plate 6 is provided with a sliding groove 8, and a sliding pressure block 9 and a support block 10 are provided inside. The bottom end of the sliding groove 8 and the bottom surface of the support block 10 are respectively provided with a limit switch one and a limit switch two. The limit switch one is used to control the lifting support platform 5 to start, and the limit switch two is used to control the lifting support platform 5 to stop. The sliding pressure block 9 is located between the limit switch one and the limit switch two, and the sliding pressure block 9 presses on the topmost plate. The top of the limiting plate 6 is provided with an adjustment mechanism 11 for adjusting the position of the support block 10.

[0023] It is worth noting that both the sheet material pushing mechanism 2 and the sheet material conveyor 3 are existing technologies. The sheet material pushing mechanism 2 includes a bracket, an electric push rod or a hydraulic push rod, and a push block. One end of the electric push rod or the hydraulic push rod is fixed on the bracket and the other end is fixedly connected to the push block. The push block pushes the sheet material to move. The sheet material conveyor 3 is a belt conveyor or a roller conveyor.

[0024] It is worth noting that the plate lifting mechanism 1 is equipped with a master control switch. Limit switches 1 and 2 only function when the master control switch is closed.

[0025] With the above structure, the position of the support block 10 is adjusted in advance by the adjustment mechanism 11 so that the distance between limit switch one and limit switch two is the thickness of the board plus the thickness of the sliding pressure block 9. When the bottom surface of the uppermost board is flush with the top surface of the board conveyor 3, the sliding pressure block 9 contacts limit switch two. When the uppermost board is pushed away, the sliding pressure block 9 falls and contacts limit switch one. When placing the board, the distance between the two limit plates 6 is the farthest. The board is placed between the two limit plates 6, with one side pressed against the baffle 7. Then the two limit plates 6 move towards the middle to restrict the board in the middle position. At this time, the sliding pressure block 9 contacts limit switch one. When the master control switch is pressed, since limit switch one is closed, the lifting support platform 5 drives the board to rise. The uppermost board drives the sliding pressure block 9 to rise. After contacting limit switch two, the lifting support platform 5 automatically stops. The board pushing mechanism 2 pushes the uppermost board to the board conveyor 3. Then the sliding pressure block 9 automatically falls and contacts limit switch one, and the lifting support platform 5 starts again.

[0026] like Figure 3As shown, the base 4 is provided with an opening groove 12, in which a bidirectional threaded rod 13 is rotatably provided. The bottom end of the limiting plate 6 is located in the opening groove 12, and it is provided with a threaded through hole 14 that cooperates with the bidirectional threaded rod 13.

[0027] It is worth noting that a drive motor is provided at one end of the bidirectional threaded rod 13 to drive the bidirectional threaded rod 13 to rotate, thereby driving the limit plate 6 to open and close.

[0028] The top of the baffle 7 is flush with the top surface of the plate conveyor 3.

[0029] The above structure ensures that the baffle 7 does not obstruct the pushing of the plate and can prevent the plate below from shifting.

[0030] like Figure 4 As shown, the bottom of the sliding pressure block 9 is provided with a roller 15, which is in contact with the plate.

[0031] The above structure reduces friction, making it easier to push the top plate.

[0032] like Figure 2 , 4 As shown in Figure 5, the top of the support block 10 is provided with an adjusting screw 16, and the limiting plate 6 is provided with a corresponding threaded through hole 17. The adjusting screw 16 passes through the threaded through hole 17 and extends to the top of the limiting plate 6. The top of the adjusting screw 16 is provided with a rotating handle.

[0033] With the above structure, since the adjusting screw 16 is engaged with the threaded through hole 17, rotating the adjusting screw 16 can drive the support block 10 to move up and down.

[0034] like Figure 4 , 5 As shown, the bottom end of the chute 8 is flush with the top surface of the plate conveyor 3, and a scale 18 is provided on one side of the chute 8.

[0035] The position of the support block 10 can be adjusted according to the thickness of the plate using the above structure.

[0036] like Figure 6 As shown, the lifting support platform 5 is a scissor lift.
