Description

Technical Field

[0001] This utility model belongs to the field of laser processing, and specifically relates to a material silo structure that reduces the combustion of waste materials from laser processing of paperboard. Background Technology

[0002] Laser processing is a technology that uses a laser beam to process objects. It has the advantages of high precision, high efficiency, and the ability to process diverse shapes, and is widely used in many processing fields. Among them, laser processing has a significant advantage in the field of cardboard processing. Since most cardboard shapes are relatively complex and often have hollowed-out patterns inside, traditional processing methods require multiple processing steps to shape the cardboard, resulting in low processing efficiency.

[0003] In existing technologies, such as patent document CN214769738U, a paper laser cutting machine for cardboard production is disclosed. This machine includes a laser cutting head that can move laterally and longitudinally within a plane. The laser cutting head cuts paper, and nitrogen nozzles are located on both sides of the laser cutting head, while a dust suction nozzle is located on the front of the laser cutting head. Nitrogen gas protects the paper from combustion during cutting, and the dust suction nozzle removes waste, preventing environmental pollution. However, because the dust suction nozzle draws waste upwards, the waste can easily escape the nitrogen protection, and it can easily come into contact with the laser beam emitted from the laser cutting head, posing a risk of waste combustion. Summary of the Invention

[0004] To address the problems in existing technologies, this utility model proposes a material storage structure that reduces the combustion of waste materials from laser processing of paperboard. By setting a transition section between the material collection section and the collection bin of the storage body, the depth of the storage body is increased, and the collection bin is moved away from the laser beam, thus solving the problem in existing technologies where the laser beam easily causes waste materials to burn.

[0005] This invention is implemented as follows: A material storage structure for reducing the combustion of waste from laser processing of paperboard is located below the worktable of a laser processing equipment. It includes a semi-enclosed storage body with an upward opening. Multiple discharge holes are provided on the worktable, connecting the worktable surface to the storage body. The upward opening of the storage body forms a collection section, which has first guiding surfaces on at least two sides that gradually slope inward from top to bottom. The discharge holes separate processing waste from finished products. Waste generated during paperboard processing falls into the storage body through these holes, allowing it to be discharged from the worktable promptly, preventing it from being irradiated by the laser beam and thus reducing the risk of combustion. The collection section collects the processing waste falling from the discharge holes, preventing it from being discharged outside the laser processing equipment and improving the reliability of the storage body.

[0006] The bottom of the chamber is equipped with a collection chamber, and the front of the collection chamber is also equipped with a detachable drawer-type collection unit. The drawer-type collection unit is slidably connected to the collection chamber and can be installed or removed by pulling it out. The drawer-type collection unit is used to temporarily store the processing waste collected by the collection section, which extends the cleaning cycle of the collection chamber and thus improves the processing efficiency of the laser processing equipment. At the same time, when the drawer-type collection unit is detachably slidably connected to the chamber, it can be quickly installed and removed, which improves the efficiency of cleaning the chamber and further shortens the maintenance time of the chamber, thereby improving the processing efficiency of the laser processing equipment.

[0007] The hopper also includes a transition section between the drawer-type collection unit and the material collection section, the height of which is greater than the height of the drawer-type collection unit. This transition section increases the depth of the hopper, moving the drawer-type collection unit further away from the workbench and thus reducing the risk of waste combustion.

[0008] Preferably, the transition section has symmetrically arranged exhaust vents on both sides, the exhaust vents are close to the material collection section, and one of the exhaust vents is connected to an external air extraction device. When the exhaust vents extract air, they promote the airflow near the workbench towards the hopper, making it easier for processing waste to fall into the discharge hole. Since the exhaust vents are close to the material collection section and far from the drawer-type collection unit, the airflow generated by the exhaust vents will not affect the processing waste in the drawer-type collection unit; and different suction intensities can be set according to the size and weight of the processing waste to avoid a mismatch between the suction intensity and the size and weight of the processing waste, which would prevent the processing waste from falling into the drawer-type collection unit.

[0009] Specifically, an isolation net is installed at the exhaust port connected to the external exhaust device, and the isolation net has multiple perforations for gas to pass through; a sealing plate is installed at another exhaust port, and the sealing plate covers the exhaust port. The isolation net is used to prevent processing waste from being drawn out from the exhaust port, thereby preventing processing waste from clogging the external exhaust device and improving the reliability of the exhaust port.

[0010] Preferably, the collection bin is further provided with a partition plate, which divides the collection bin into multiple collection chambers. Multiple drawer-type collection units are provided, each corresponding to a collection chamber and slidably installed within it. When the collection bin is divided into multiple collection chambers, the capacity of a single collection chamber is reduced while maintaining the overall capacity of the collection bin. This reduces the weight of each drawer-type collection unit after collecting processing waste, facilitating cleaning and improving the convenience of the drawer-type collection unit.

[0011] Specifically, the bottom of the collection cavity is also provided with a support portion adapted to the drawer-type collection unit. The cross-section of the support portion is L-shaped, including a horizontally arranged support section and a vertically arranged guide section. The support portion is used to improve the load-bearing capacity of the collection cavity, thereby preventing the collection cavity from deforming under the load of the drawer-type collection unit and improving the service life of the collection cavity. The guide section is used to guide the drawer-type collection unit when it is pulled out, preventing it from getting stuck and improving the convenience of the drawer-type collection unit.

[0012] Specifically, the transition section is provided with an installation groove corresponding to the partition plate, and the top of the partition plate is provided with a connecting groove. The installation groove and the connecting groove form an insertion groove, in which a detachable baffle is inserted. The baffle is used to divide the transition section into multiple transition cavities corresponding to the collection chamber, making each transition cavity relatively independent. Since the processing waste generated in different parts of the paperboard may vary in size and weight, dividing the transition section into multiple transition cavities by the partition plate can separate the heavy and large-volume processing waste from the light and small-volume processing waste generated in different parts of the processed part. This prevents the light and small-volume processing waste from flying around in the transition section and thus prevents it from falling into the drawer-type collection unit, improving the reliability of the transition section.

[0013] Specifically, the top of the partition plate is provided with a second guide surface that gradually slopes downward from the middle to both sides. The second guide surfaces on both sides of the partition plate are symmetrically arranged and extend to the top of the drawer-type collection unit, ensuring that the processing waste can fall into the drawer-type collection unit and improving the reliability of the partition plate.

[0014] Preferably, the top of the collecting section extends upward to form a mounting section, which has multiple mounting holes. Compared to a laterally extending mounting section, the upwardly extending mounting section does not obstruct the flow of processing waste into the collecting section, ensuring both the secure installation of the hopper and the reliability of the collecting section.

[0015] Specifically, the mounting hole extends laterally and / or longitudinally in the shape of a long groove. Since the machining and installation errors of the hopper are unavoidable, the long groove-shaped mounting hole can prevent the hopper from being unable to be installed due to the cumulative error of the machining and installation errors, thus improving the reliability of the mounting hole.

[0016] Preferably, the hopper body is constructed by splicing and / or welding multiple sheet metal parts. This reduces the size of the hopper body while ensuring its structural strength and improves its ease of installation.

[0017] The beneficial effects of this utility model are:

[0018] This invention proposes a material storage structure to reduce the combustion of waste from laser processing of paperboard. By setting a transition section between the material collection section and the collection bin, the depth of the storage body is increased, so that the collection bin is far away from the laser beam, thereby keeping the processing waste away from the laser head and preventing the processing waste from burning.

[0026] 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 a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-5 As shown, a material storage structure 2 for reducing the combustion of waste from laser processing of cardboard is located below the worktable 11 of the laser processing equipment 1. It includes a semi-enclosed storage chamber 21 with an upward opening. The worktable 11 has multiple discharge holes that connect the worktable surface and the storage chamber 21.

[0028] In this embodiment, the chamber 21 is assembled from multiple sheet metal parts. While ensuring the structural strength of the chamber 21, its volume is reduced, and its installation convenience is improved.

[0029] The upward opening of the chamber 21 forms a collection section 212. The collection section 212 has first guide surfaces that are gradually inclined inward from top to bottom on at least two sides. The discharge hole is used to separate processing waste and finished products. Waste generated during the processing of the cardboard falls into the chamber 21 through the discharge hole, so that the processing waste can be discharged from the worktable 11 in a timely manner, avoiding the processing waste from being irradiated by the laser beam, thereby reducing the risk of processing waste combustion. The collection section 212 is used to collect the processing waste falling from the discharge hole, preventing the processing waste from being discharged outside the laser processing equipment 1, and improving the reliability of the chamber 21.

[0030] In this embodiment, the top of the collecting part 212 extends upward to form a mounting part 211, and the mounting part 211 is provided with a plurality of mounting holes 2111. Compared with the horizontally extending mounting part 211, the upwardly extending mounting part 211 will not obstruct the processing waste from falling into the collecting part 212, thus ensuring the reliability of the collecting part 212 while ensuring the secure installation of the hopper 21.

[0031] Specifically, the mounting hole 2111 extends laterally and is in the shape of a long groove. Since the processing and installation errors of the chamber 21 are unavoidable, the long groove-shaped mounting hole 2111 can prevent the chamber 21 from being unable to be installed due to the cumulative error of the processing and installation errors, thereby improving the reliability of the mounting hole 2111.

[0032] The bottom of the chamber 21 is provided with a collection chamber 214, and the front of the collection chamber 214 is also provided with a detachable drawer-type collection unit 22. The drawer-type collection unit 22 is slidably connected to the collection chamber 214 and can be installed or removed by pulling out. The drawer-type collection unit 22 is used to temporarily store the processing waste collected by the collection section 212, which extends the cleaning cycle of the collection chamber 214 and thus improves the processing efficiency of the laser processing equipment 1. At the same time, when the drawer-type collection unit 22 is slidably connected to the chamber 21, it can be quickly installed and removed, which improves the efficiency of cleaning the chamber 21, further shortens the maintenance time of the chamber 21, and improves the processing efficiency of the laser processing equipment 1.

[0033] In this embodiment, the drawer-type collection unit 22 is a drawer.

[0034] The hopper 21 also includes a transition section 213 disposed between the drawer-type collection unit 22 and the material collection section 212. The height of the transition section 213 is greater than the height of the drawer-type collection unit 22. The transition section 213 increases the depth of the hopper 21, moving the drawer-type collection unit 22 away from the workbench 11, further reducing the risk of combustion of processing waste.

[0035] In this embodiment, vents are symmetrically arranged on both sides of the transition section 213. The vents are close to the collection section 212, and one of the vents is connected to an external air extraction device. When the vents extract air, they promote the airflow near the workbench 11 towards the hopper 21, making it easier for processing waste to fall into the discharge hole. Since the vents are close to the collection section 212 and far from the drawer-type collection unit 22, the airflow generated by the vents will not affect the processing waste in the drawer-type collection unit 22. Furthermore, different suction intensities can be set according to the size and weight of the processing waste to avoid a mismatch between the suction intensity and the size and weight of the processing waste, which would prevent the processing waste from falling into the drawer-type collection unit 22.

[0036] Specifically, an isolation net 23 is provided at the exhaust port connected to the external exhaust device, and the isolation net 23 has multiple perforations for gas to pass through; a sealing plate 24 is provided at another exhaust port, and the sealing plate 24 covers the exhaust port. The isolation net 23 is used to prevent processing waste from being drawn out from the exhaust port, thereby preventing processing waste from clogging the external exhaust device and improving the reliability of the exhaust port.

[0037] In this embodiment, a partition plate 216 is also provided inside the collection chamber 214, which divides the collection chamber 214 into multiple collection cavities. Multiple drawer-type collection units 22 are provided, each corresponding to a collection cavity and slidably installed within the cavity. When the collection chamber 214 is divided into multiple collection cavities, the capacity of a single collection cavity can be reduced while maintaining the overall capacity of the collection chamber 214. This reduces the weight of a single drawer-type collection unit 22 after collecting processing waste, making it easier for workers to clean the drawer-type collection unit 22 and improving its convenience.

[0038] Specifically, the bottom of the collection cavity is further provided with a support portion 217 adapted to the drawer-type collection unit 22. The support portion 217 has an L-shaped cross-section, including a horizontally arranged support section 2172 and a vertically arranged guide section 2171. The support portion 217 is used to improve the load-bearing capacity of the collection cavity, thereby preventing the collection cavity from deforming under the load of the drawer-type collection unit 22 and improving the service life of the collection cavity. The guide section 2171 is used to guide the drawer-type collection unit 22 when it is pulled out, preventing it from getting stuck. In other embodiments, a removable baffle is inserted into the insertion slot, improving the convenience of the drawer-type collection unit 22.

[0039] Specifically, the transition section 213 is provided with an installation groove 215 corresponding to the partition plate 216, and the top of the partition plate 216 is provided with a connecting groove 218. The installation groove 215 and the connecting groove 218 form an insertion groove. The baffle is used to divide the transition section 213 into multiple transition cavities corresponding to the collection cavity, so that each transition cavity is relatively independent. Since the processing waste generated in different parts of the paperboard may vary in size and weight, when the transition section 213 is divided into multiple transition cavities by the partition plate 216, when large-weight, large-volume processing waste and small-weight, small-volume processing waste are generated in different parts of the processed part, the partition plate 216 can isolate the large-weight, large-volume processing waste and the small-weight, small-volume processing waste, preventing the small-weight, small-volume processing waste from flying in the transition section 213 and causing the small-weight, small-volume processing waste to not fall into the drawer-type collection unit 22, thus improving the reliability of the transition section 213.

[0040] Specifically, the top of the partition plate 216 is provided with a second guide surface 2161 that gradually slopes downward from the middle to both sides. The second guide surfaces 2161 on both sides of the partition plate 216 are symmetrically arranged and extend to the top of the drawer-type collection unit 22, ensuring that the processing waste can fall into the drawer-type collection unit 22, thereby improving the reliability of the partition plate 216.

[0041] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
