Abstract
Description
Technical Field
[0001] This utility model belongs to the field of burr removal technology, and in particular relates to an automatic material sorting and sandblasting burr removal device. Background Technology
[0002] Traditional burr removal devices include grinding removal and sandblasting removal. Sandblasting removal uses fine sand that comes into high-speed contact with the burr forming part to impact and detach the burr from the workpiece. During the impact process, the fine sand moves together with the burr that has detached from the workpiece and collects it in a preset position for recycling.
[0003] However, in existing sandblasting burr removal devices, the housing for collecting fine sand is equipped with a filter screen to separate fine sand and burr particles. However, the filter screen has a short filtration time and a generally poor filtration effect. Some burrs will still flow back into the sandblasting device along with the fine sand, resulting in a decrease in the purity of the fine sand and affecting the burr removal effect. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic material dispensing and sandblasting burr removal device, which aims to solve the technical problem in the prior art where the burr and fine sand are poorly separated and some burrs still flow back into the sandblasting device along with the fine sand, resulting in a decrease in the purity of the fine sand.
[0005] To achieve the above objectives, this utility model provides an automatic material distribution, sandblasting, and burr removal device, comprising a base, a sandblasting unit, a limiting fixture, and a fine sand recovery mechanism. The sandblasting unit is mounted on the base. The limiting fixture is mounted on the base and located at the output end of the sandblasting unit, and the limiting fixture is provided with a limiting groove for accommodating workpieces. The fine sand recovery mechanism includes a multi-layer collection box, filter screens, and a direct vibration unit. The multi-layer collection box is located at the bottom of the base and below the sandblasting unit. The number of filter screens is at least one set, and all the filter screens are spaced apart within the multi-layer collection box. The pore diameter of all the filter screens decreases sequentially along the direction of gravity. The multi-layer collection box is provided with multiple discharge ports, each aligned with one of the ends of the filter screens.
[0006] Optionally, the multi-layer collection box includes a box body and a discharge assembly. The box body is provided with an open cavity. The discharge assembly is located at the end of the box body. All the filter screens are spaced apart in the open cavity and divide the open cavity into at least two sets of collection channels. The output end of the direct vibration unit is driven and connected to the box body. The discharge assembly is provided with a plurality of discharge ports that are respectively aligned with the corresponding collection channels.
[0007] Optionally, mounting blocks for mounting the filter screen are provided on two opposing inner walls inside the open cavity, with the two ends of the filter screen overlapping the corresponding mounting blocks.
[0008] Optionally, the mounting block is arranged in the form of a long strip plate, the mounting block is arranged in a horizontal direction, and the length of the mounting block is equal to that of the filter screen.
[0009] Optionally, the end of the housing away from the discharge assembly is provided with a guide frame for guiding the burrs and fine sand into the open cavity.
[0010] Optionally, the number of filter screens is two sets, and all the filter screens are sequentially and spaced apart in the open cavity, dividing the open cavity into three sets of collection channels; the discharge assembly includes a first discharge seat, a second discharge seat, and a third discharge seat, the input ends of the first discharge seat, the second discharge seat, and the third discharge seat are respectively set at the ends of the corresponding collection channels, and the number of discharge ports is three sets, with the three sets of discharge ports respectively formed at the ends of the first discharge seat, the second discharge seat, and the third discharge seat away from the collection channels.
[0011] Optionally, the output orientation of the three sets of discharge ports is different.
[0012] Optionally, the third discharge seat is provided with an inclined funnel-shaped structure, and the end of the third discharge seat away from the collection channel gradually slopes downward, with the discharge port located at the end of the third discharge seat away from the collection channel.
[0013] Optionally, the second discharge seat is arranged in a horizontal direction.
[0014] Optionally, the bottom of the housing is provided with an elastic cushioning component.
[0015] The automatic material sorting and sandblasting burr removal device provided in this utility model embodiment has at least one of the following technical effects: After the fine sand sprayed by the sandblasting unit impacts the workpiece, the mixture formed by the fine sand and burr enters the multi-layer collection box. The direct vibration unit drives the multi-layer collection box to vibrate, so that the mixture moves along the length of the filter screen. At the same time, the pore size of the filter screen is between that of the burr and the fine sand. Particles smaller than the current pore size of the filter screen fall below the filter screen. After being driven by the direct vibration unit, the separated and filtered fine sand and burr move synchronously to the discharge port and are output to the preset discharge position.

The following description is based on the accompanying drawings. Figures 1-5 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0032] In one embodiment of this utility model, such as Figures 1-5 As shown, an automatic material sorting, sandblasting, and burr removal device is provided, including a base 100, a sandblasting unit 200, a limiting fixture, and a fine sand recovery mechanism 300. The sandblasting unit 200 is disposed on the base 100. The limiting fixture is disposed on the base 100 and located at the output end of the sandblasting unit 200, and the limiting fixture is provided with a limiting groove for accommodating workpieces. The fine sand recovery mechanism 300 includes a multi-layer collection box 310, a filter screen 320, and a direct vibration unit. The multi-layer collection box 310 is disposed at the bottom of the base 100 and located below the sandblasting unit 200. The number of filter screens 320 is at least one set, and all the filter screens 320 are spaced apart in the multi-layer collection box 310. The pore diameter of all the filter screens 320 decreases sequentially along the direction of gravity. The multi-layer collection box 310 is provided with multiple discharge ports that are respectively aligned with the ends of the filter screens 320.
[0033] Specifically, after the fine sand sprayed by the sandblasting unit 200 impacts the workpiece, the mixture formed by the fine sand and burrs enters the multi-layer collection box 310. The direct vibration unit drives the multi-layer collection box 310 to vibrate, causing the mixture to move along the length of the filter screen 320. At the same time, the aperture of the filter screen 320 is between that of the burrs and the fine sand. Particles smaller than the current aperture of the filter screen 320 fall below the filter screen 320. After being driven by the direct vibration unit, the separated and filtered fine sand and burrs move synchronously to the discharge port and are output to the preset discharge position. Compared with the existing technology where the burrs and fine sand are poorly separated and some burrs still flow back into the sandblasting device with the fine sand, resulting in a decrease in the purity of the fine sand, the automatic material distribution sandblasting burr removal device provided by this utility model separates the burrs and fine sand by adding a direct vibration filter screen 320 structure during the fine sand return collection process, thereby effectively improving the purity of the recovered fine sand and further improving the burr removal efficiency.
[0034] like Figures 1-5 As shown, in another embodiment of this utility model, the multi-layer collection box 310 includes a box body 311 and a discharge assembly 312. The box body 311 is provided with an open cavity 313, and the discharge assembly 312 is disposed at the end of the box body 311. All the filter screens 320 are spaced apart in the open cavity 313, dividing the open cavity 313 into at least two sets of collection channels. The output end of the direct vibration unit is drivenly connected to the box body 311. The discharge assembly 312 is provided with a plurality of discharge ports that are respectively aligned with the corresponding collection channels. The direct vibration unit is a vibrator, the box body 311 is configured with a cuboid structure, and the filter screens 320 are configured with a rigid plate structure.
[0035] like Figures 1-5 As shown, in another embodiment of this utility model, mounting blocks 314 for mounting the filter screen 320 are provided on two opposing inner walls inside the open cavity 313, and the two ends of the filter screen 320 overlap on the corresponding mounting blocks 314. The overlapping filter screen 320 structure facilitates easy assembly and disassembly of the filter screen 320, thereby adapting to the corresponding dimensions of workpiece burrs or fine sand of different sizes.
[0036] like Figures 1-5 As shown, in another embodiment of this utility model, the mounting block 314 is arranged in the form of a long strip plate, the mounting block 314 is arranged in a horizontal direction, and the length of the mounting block 314 is equal to that of the filter screen 320. Using filter screen 320 and mounting block 314 of equal length helps to improve the installation stability of mounting block 314 and filter screen 320.
[0037] like Figures 1-5As shown, in another embodiment of this utility model, the end of the housing 311 away from the discharge assembly 312 is provided with a guide frame 315 for guiding the burrs and fine sand to move into the open cavity 313. Using the guide frame 315 to guide the material helps prevent the material from scattering and falling, improves the concentration of the material, and facilitates the efficient recovery of fine sand.
[0038] like Figures 1-5 As shown, in another embodiment of this utility model, the number of filter screens 320 is two sets, and all the filter screens 320 are sequentially and spaced apart in the open cavity 313, dividing the open cavity 313 into three sets of collection channels; the discharge assembly 312 includes a first discharge seat 316, a second discharge seat 317 and a third discharge seat 318, the input ends of the first discharge seat 316, the second discharge seat 317 and the third discharge seat 318 are respectively set at the ends of the corresponding collection channels, and the number of discharge ports is three sets, and the three sets of discharge ports are respectively formed at the ends of the first discharge seat 316, the second discharge seat 317 and the third discharge seat 318 away from the collection channels.
[0039] In this embodiment, since the fine sand gradually breaks into smaller fine sand particles during the reciprocating impact of the workpiece, the filter pore diameter of the filter screen 320 is shortened from top to bottom to filter and separate burr particles, fine sand particles and small fine sand particles.
[0040] like Figures 1-5 As shown, in another embodiment of this invention, the three sets of discharge ports have different output orientations. This helps to prevent material particles from being discharged from the discharge ports and ensures that they are collected by their respective receiving units.
[0041] like Figures 1-5 As shown, in another embodiment of this utility model, the third discharge seat 318 is arranged in an inclined funnel shape. The end of the third discharge seat 318 away from the collection channel gradually slopes downward. The discharge port is located at the end of the third discharge seat 318 away from the collection channel. The inclined structure of the third discharge seat 318 is beneficial to improving the movement efficiency of small particles, thereby improving the fine sand collection efficiency.
[0042] like Figures 1-5 As shown, in another embodiment of this utility model, the second discharge seat 317 is arranged in a horizontal direction. The second discharge seat 317, which is arranged with an output direction different from that of the third discharge seat 318, can make it easier for users to distinguish the output particle size and prevent mixed materials from being stored.
[0043] like Figures 1-5As shown, in another embodiment of this utility model, an elastic buffer assembly 400 is provided at the bottom of the box 311. The elastic buffer assembly 400 includes a support column and a compression spring disposed on the support column. The elastic buffer assembly 400 helps to prevent the box 311 from rigidly contacting the support surface. At the same time, during the buffering process, the filter screen 320 vibrates synchronously with the box 311, which helps to improve the material filtration speed and further improve the fine sand circulation efficiency.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
