Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically a cutting machine for processing dispensing-type rapid prototyping trays. Background Technology

[0002] In the manufacturing process of dispensing rapid prototyping pallets, the cutting process plays a crucial role, directly determining the pallet's dimensional accuracy and molding quality. Only precise cutting can provide a solid foundation for the subsequent dispensing and bonding process, ensuring that the finished pallet meets quality standards. Currently, most traditional cutting machines employ a mechanical structure combining a fixed blade holder and a linear guide rail. A motor drives the blade holder to move linearly along the guide rail, thus completing the cutting operation of the pallet material. During the cutting process, the machine removes excess material from the pallet to facilitate subsequent dispensing and bonding. However, the removal of waste material after it is cut from the pallet becomes a significant aspect of the manufacturing process.

[0003] Existing waste removal methods generally use negative pressure fans to circulate air and suck up the waste. However, this method has significant drawbacks. In actual use, waste easily clogs the air ducts. Once the ducts are clogged, it not only affects the normal removal of waste but may also cause a significant decrease in the efficiency of the entire waste removal system, or even cause it to stop working, seriously affecting the continuity of the cutting process and the production efficiency of pallet processing. Therefore, developing a dispensing-type rapid prototyping pallet cutting machine that can effectively avoid waste clogging the air ducts and improve waste removal efficiency is of great practical significance. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting machine for dispensing rapid prototyping trays, addressing the defects and shortcomings of existing technologies.

[0005] This utility model provides a cutting machine for dispensing-type rapid prototyping trays, comprising:

[0006] Organism;

[0007] The worktable assembly is located on the top of the machine body and is capable of fixing the tray and rotating the tray.

[0008] A cutting component is also provided on the top of the machine body near the back of the worktable assembly, which can be used to cut off excess material from the tray;

[0009] A collection box, located inside the machine body, is used to collect the cut-off waste.

[0010] The workbench assembly includes a rotating platform rotatably mounted on the top of the machine body, and a flip plate that can be flipped is rotatably mounted on the rotating platform via an axis. A support platform is also fixed on the top of the flip plate. When the waste is cut off, the flip plate can flip to send the waste into the collection box.

[0011] Preferably, the support platform has several air holes that allow air to pass through, the support platform has a cavity inside, and the air holes are connected to the cavity.

[0012] Preferably, the support platform is also connected to an external vacuum pump via a pipe, which is connected to the cavity inside the support platform.

[0013] Preferably, the worktable assembly includes a first rotary drive unit mounted on the bottom of the machine body for driving the rotary table to rotate, and the output end of the first rotary drive unit is connected to the bottom of the rotary table.

[0014] Preferably, the top of the rotary table is also provided with a drive mechanism that can drive the flip plate to flip.

[0015] Preferably, the driving mechanism includes bearing seats distributed at both ends of the top of the rotary table, and a lead screw is rotatably arranged between the two bearing seats. The driving mechanism includes a second rotary driving component fixed to the top of the rotary table, and the output end of the second rotary driving component is connected to the lead screw. A moving block is also threadedly connected to the lead screw, and a connecting rod is rotatably arranged on the moving block. One end of the connecting rod is rotatably connected to the bottom of the flip plate.

[0016] Preferably, the cutting assembly includes a cutting blade that can move up and down and can contact the tray to cut off the waste material from the tray.

[0017] Preferably, the cutting assembly further includes a first moving mechanism fixed on the machine body, and a second moving mechanism perpendicular to the first moving mechanism is also provided on the first moving mechanism. A third moving mechanism is vertically provided on the second moving mechanism, and the third moving mechanism is connected to the cutting blade through a blade holder.

[0018] The advantages of this utility model application compared to the prior art are:

[0019] This application achieves waste processing and stable pallet fixation through a configured workbench assembly. The workbench assembly is mounted on the machine body, and its core structure includes a rotary table that rotates on the machine body. A tilting plate is rotatably mounted on the rotary table via an axis. In the waste processing flow, after the waste on the pallet is cut off, a second rotary drive is activated. The second rotary drive drives a lead screw to rotate. As the lead screw rotates, a moving block moves linearly along the axis of the lead screw. The moving block is hinged to one end of a connecting rod, and the other end of the connecting rod is hinged to the tilting plate. Through this linkage mechanism, the linear movement of the moving block is converted into the movement of the connecting rod, which in turn drives the tilting plate to tilt around its axis with the rotary table. After the tilting plate tilts, the waste on the pallet slides into a collection box under gravity for centralized storage. To ensure the pallet remains stable during waste cutting and tilting and to prevent slippage, this application employs vacuum adsorption technology. A vacuum is generated by an external vacuum pump, creating a negative pressure environment between the support platform and the tray. This allows the tray to adhere tightly to the support platform, effectively preventing it from slipping and ensuring the stability and safety of the entire processing. Attached Figure Description

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] Reference Figures 1-6 As shown, this utility model application provides a cutting machine for processing trays using a dispensing-type rapid prototyping method, including a machine body 1; a worktable assembly 2, which is provided on the top of the machine body 1 and can fix and rotate the tray; a cutting assembly 3, which is provided on the top of the machine body 1 near the back of the worktable assembly 2 and can be used to cut off excess material from the tray; and a collection box 4, which is provided inside the machine body 1 and can collect the cut waste material. The worktable assembly 2 includes a rotating table 23 rotatably disposed on the top of the machine body 1, and a flipping plate 22 rotatably disposed on the rotating table 23 via a shaft. A support platform 21 is also fixed on the top of the flipping plate 22. When the waste material is cut off, the flipping plate 22 can flip and send the waste material into the collection box 4.

[0029] In the dispensing-based rapid prototyping pallet processing, the pallet to be processed is first placed on the support platform 21 of the worktable assembly 2, and the worktable assembly 2 ensures stable placement of the pallet. Then, the cutting assembly 3 is activated to remove excess material from the pallet. During the cutting process, the rotary table 23 of the worktable assembly 2 can rotate the pallet as needed, allowing the cutting assembly 3 to cut different parts of the pallet to meet diverse processing requirements. After the excess material on the pallet is removed, the flipping plate 22 flips over, sending the removed waste material into the collection box 4 inside the machine body 1, completing the automatic collection of waste material.

[0030] The support platform 21 has several air holes 211 for ventilation. The inside of the support platform 21 is a cavity, and the air holes 211 are connected to the cavity. The outside of the support platform 21 is also connected to a pipe 212 that is connected to an external vacuum pump. The pipe 212 is connected to the cavity inside the support platform 21.

[0031] Start the external vacuum pump. The vacuum pump begins to work, drawing air from the internal cavity of the support platform 21 through pipe 212, creating a negative pressure environment inside the cavity. Since the air vents 211 are connected to the cavity, the negative pressure inside the cavity is quickly transmitted to each air vent 211. At this time, the tray is placed on the support platform 21, and the negative pressure at the air vents 211 generates an adsorption force on the tray, firmly adhering the tray to the support platform 21, thus achieving stable fixation of the tray.

[0032] The worktable assembly 2 includes a first rotary drive 231 mounted on the bottom of the machine body 1 for driving the rotary table 23 to rotate, and the output end of the first rotary drive 231 is connected to the bottom of the rotary table 23.

[0033] When it is necessary to cut the pallet at different locations, the first rotary drive 231 is activated. The first rotary drive 231 begins operation, and since its output end is connected to the bottom of the rotary table 23, the rotational motion of the output end is directly transmitted to the rotary table 23, causing it to rotate around its axis of rotation. As the rotary table 23 rotates, the pallet placed on the support platform 21 also changes position, allowing the cutting assembly 3 to perform cutting operations on different parts of the pallet as needed.

[0034] The top of the rotary table 23 is also provided with a drive mechanism 24 for driving the tilting plate 22 to tilt. The drive mechanism 24 includes bearing seats distributed at both ends of the top of the rotary table 23, and a lead screw 241 is rotatably arranged between the two bearing seats. The drive mechanism 24 includes a second rotary drive component 244 fixed to the top of the rotary table 23, and the output end of the second rotary drive component 244 is connected to the lead screw 241. A moving block 242 is also threadedly connected to the lead screw 241, and a connecting rod 243 is rotatably arranged on the moving block 242. One end of the connecting rod 243 is rotatably connected to the bottom of the tilting plate 22.

[0035] When the waste material removed from the pallet placed on the support platform 21 needs to be sent into the collection box 4, the second rotary drive 244 is activated. The second rotary drive 244 begins operation, and its output end drives the lead screw 241 to rotate around its own axis. Since the moving block 242 is connected to the lead screw 241 via a thread, during the rotation of the lead screw 241, according to the principle of threaded transmission, the moving block 242 will move linearly along the axis of the lead screw 241. With the linear movement of the moving block 242, the connecting rod 243, which is rotatably connected to it, will change angle. The other end of the connecting rod 243 is rotatably connected to the bottom of the tilting plate 22. The change in the angle of the connecting rod 243 will apply a thrust to the tilting plate 22, causing the tilting plate 22 to tilt around its rotation axis with the rotating platform 23. When the tilting plate 22 tilts to a suitable angle, the waste material placed on the support platform 21 will fall into the collection box 4 under gravity, completing the waste collection. When it is necessary to reset the flip plate 22, the second rotary drive 244 is controlled to rotate in the opposite direction, the lead screw 241 will also rotate in the opposite direction, the moving block 242 will move in a straight line in the opposite direction along the lead screw 241, and the angle of the connecting rod 243 will gradually recover, thereby driving the flip plate 22 to flip in the opposite direction and return to the initial position for the next pallet processing operation.

[0036] The cutting assembly 3 includes a cutting blade 34 that can move up and down and contact the tray to cut off the waste material from the tray. The cutting assembly 3 also includes a first moving mechanism 31 fixed to the machine body 1, and a second moving mechanism 32 perpendicular to the first moving mechanism 31 is also provided on the first moving mechanism 31. A third moving mechanism 33 is vertically provided on the second moving mechanism 32, and the third moving mechanism 33 is connected to the cutting blade 34 through a blade holder.

[0037] After the pallet is placed on the workbench assembly 2 and secured, the cutting assembly 3 begins to operate. First, based on the location on the pallet that needs to be cut, the first moving mechanism 31 is activated, driving the second moving mechanism 32, the third moving mechanism 33, and the cutting blade 34 to move together in one direction in the horizontal plane, bringing the cutting blade 34 close to the area on the pallet that needs to be cut, thereby removing the waste material from the pallet.

[0038] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
