Description

Technical Field

[0001] This utility model relates to the field of CNC machining auxiliary equipment, and in particular to a waste recycling device used in CNC machining process. Background Technology

[0002] CNC machining is an automated machining technology that uses computer instructions and CAM (Computer-Aided Manufacturing) programs to control the movement of machine tools, achieving high-precision and high-efficiency manufacturing. When CNC machining metal workpieces, a large amount of debris and waste is generated. This debris and waste can be recycled and processed as recycled materials, which has strong economic and environmental significance.

[0003] Existing waste recycling devices in CNC machining processes generally use blowers to blow debris into collection containers or vacuum pumps to create negative pressure to suck away debris. However, as the amount of debris increases, workers need to periodically transfer the waste in the collection containers, which is time-consuming and labor-intensive. In addition, the waste is relatively loose and not easy to transport, resulting in low waste recycling efficiency. Utility Model Content

[0004] To overcome the shortcomings of existing waste recycling devices, which require workers to periodically transfer waste from the collection container, which is time-consuming and labor-intensive, and the waste is relatively loose and inconvenient to transport, resulting in low waste recycling efficiency, this utility model provides a waste recycling device for CNC machining processes that can transfer and compress waste into blocks when the weight reaches a certain level, and can automatically discharge the compressed waste blocks, thereby improving waste recycling efficiency.

[0005] The technical solution of this utility model is: a waste recycling device for CNC machining process, including a base frame, and a guide groove is opened in the lower part of the base frame;

[0006] Machining centers mounted on a base frame;

[0007] The housing is fixed to the base frame and machining center;

[0008] The filter screen is fixed to the upper part of the housing;

[0009] Two guide frames are fixed to the base frame and the machining center;

[0010] U-shaped frame fixed to the base frame;

[0011] A limiting plate fixed to the base frame;

[0012] The pushing mechanism is installed on the base frame, machining center, guide frame, U-shaped frame and limit plate;

[0013] The pressing mechanism is installed on the base frame and the pushing mechanism;

[0014] The discharge mechanism is located on the base frame and the briquetting mechanism.

[0015] Furthermore, the pushing mechanism includes two air jet frames disposed within the machining center, four guide cylinders fixed to the U-shaped frame, a material support frame slidably connected between the four guide cylinders, four return springs disposed between the material support frame and the guide cylinders, a hydraulic push rod fixed to the base frame, a sliding plate slidably connected to the base frame, one side of the sliding plate slidably connected to the telescopic rod of the hydraulic push rod, a sliding plate 2 slidably connected to the base frame, two connecting frames fixed between the sliding plate 1 and the sliding plate 2, the connecting frames being slidably connected to the U-shaped frame and the limiting plate, a switch 1 fixed to one of the guide frames, and a switch 2 fixed to the U-shaped frame, both of which are electrically connected to the hydraulic push rod.

[0016] Furthermore, the pressing mechanism includes a cylinder fixed to the base frame, two openings on one side of the cylinder, a pressing frame slidably connected to the cylinder, a sliding frame slidably connected to the base frame, and a removal component disposed on the sliding frame.

[0017] Furthermore, the removal assembly includes a first limiting frame fixed to the sliding frame, a second limiting frame slidably connected to the sliding frame, one side of the first limiting frame and the second limiting frame respectively blocking the two openings of the cylinder body, a second reset spring disposed between the second limiting frame and the sliding frame, and a contact shaft fixed to the second limiting frame, one end of the contact shaft being located in the guide groove of the base frame.

[0018] Furthermore, the discharge mechanism includes a rack frame slidably connected to the base frame, a turntable rotatably connected to the base frame, an overrunning clutch fixed to the turntable, a gear fixed to the outer ring of the overrunning clutch, the rack frame meshing with the gear, a drive shaft fixed to the turntable, a slotted frame fixed to the sliding frame, one end of the drive shaft located in the limiting slot of the slotted frame, and a top rod fixed to the sliding frame.

[0019] The beneficial effects of this utility model are as follows: 1. As the waste material accumulates, the support frame moves downward. When the weight of the waste material reaches a certain amount, the support frame presses switch two, causing the hydraulic push rod to drive sliding plate one and sliding plate two to move. Sliding plate one pushes the waste material into the cylinder. The extrusion frame extrudes the waste material that falls into the cylinder into blocks. Limiting frame one and limiting frame two drive the waste blocks away from the cylinder. Limiting frame two continues to move and disengages from the waste material. The waste blocks are discharged through the outlet of the shell. This allows the waste material to be transferred and extruded into blocks when its weight reaches a certain level, and the extruded waste blocks can be automatically discharged, improving the waste recycling efficiency.

Detailed Implementation

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1: A waste recycling device for CNC machining processes, such as... Figures 1-6 As shown, it includes a base frame 1, and a guide groove is opened in the lower part of the base frame 1;

[0031] The machining center 2 is mounted on the base frame 1, and a discharge port is opened on one side of the machining center 2;

[0032] The housing 3 is fixed to the base frame 1 and the machining center 2. The housing 3 covers the discharge port of the machining center 2, and the bottom of the housing 3 has a discharge port.

[0033] A filter screen 4 is fixed to the upper part of the housing 3, and the filter screen 4 is set at an angle.

[0034] Two guide frames 5 are fixed to the base frame 1 and the machining center 2, and the two guide frames 5 are arranged symmetrically.

[0035] The U-shaped frame 6 is fixed to the base frame 1 and is located below the two guide frames 5;

[0036] The limiting plate 7 is fixed to the base frame 1 and is located on one side of the U-shaped frame 6;

[0037] The pushing mechanism is installed on the base frame 1, machining center 2, guide frame 5, U-shaped frame 6 and limiting plate 7. The pushing mechanism is used to collect waste material and transfer it after the weight of the waste material reaches a certain level.

[0038] The briquetting mechanism, which is installed on the base frame 1 and the pushing mechanism, is used to compress waste material into blocks;

[0039] The discharge mechanism, which is installed on the base frame 1 and the briquetting mechanism, is used to discharge the waste material after it has been compressed into blocks.

[0040] The feeding mechanism includes two air jet frames 81 disposed within the machining center 2, four guide cylinders 82 fixed to the U-shaped frame 6, the four guide cylinders 82 being evenly spaced, a material support frame 821 slidably connected between the four guide cylinders 82, the two sides of the material support frame 821 being tightly fitted to the two guide frames 82 respectively, four return springs 83 disposed between the material support frame 821 and the guide cylinders 82, a hydraulic push rod 84 fixed to the base frame 1, a sliding plate 85 slidably connected to the base frame 1, one side of the sliding plate 85 being fixedly connected to the telescopic rod of the hydraulic push rod 84, and a second sliding plate 85 slidably connected to the base frame 1. 6. Sliding plate 1 85 and sliding plate 2 86 block the gap between the bottom of the guide frame 5 and the top of the U-shaped frame 6. Two connecting frames 87 are fixed between sliding plate 1 85 and sliding plate 2 86. The connecting frames 87 are slidably connected to the U-shaped frame 6 and the limiting plate 7. Switch 1 88 is fixed on one of the guide frames 5, and switch 2 89 is fixed on the U-shaped frame 6. Switch 1 88 and switch 2 89 are both electrically connected to the hydraulic push rod 84. The waste material presses the support frame 821 downward. The support frame 821 moves downward and presses switch 2 89, which in turn triggers the hydraulic push rod 84 to drive sliding plate 1 85 to push the waste material on the support frame 821 away.

[0041] Initially, the jet frame 81 is connected to the high-pressure air supply system. During operation, the operator places the workpiece into the machining center 2 for processing and closes the sealed door of the machining center 2. After processing begins, the operator continuously outputs gas to the jet frame 81 through the air supply system. The nozzles of the jet frame 81 continuously spray gas, blowing the waste generated during processing to one side and out through the discharge port on one side of the machining center 2. The filter screen 4 allows the gas to escape while intercepting the waste. The waste falls downward under the action of gravity and falls onto the receiving frame 821 under the guidance of the guide frame 5. At the top, as waste accumulates, the pressure on the support frame 821 gradually increases, causing it to move downwards. The return spring 83 is gradually compressed. When the weight of the waste reaches a certain amount, the support frame 821 moves to contact the switch 89 and presses it down, extending the telescopic rod of the hydraulic push rod 84. At this point, the top of the support frame 821 is flush with the bottom of the sliding plate 85. The telescopic rod of the hydraulic push rod 84 moves the sliding plate 85, which in turn moves the sliding plate 86 via the connecting frame 87. As the sliding plate 86 moves, it no longer blocks the gap between one of the guide frames 5 and the U-shaped frame 6. The sliding plate 85 pushes the waste material on the receiving frame 821 into the cavity formed by the U-shaped frame 6 and the limiting plate 7. Through the above operation, the waste material can be collected and transferred after the weight of the waste material reaches a certain level. The sliding plate 85 always presses against the receiving frame 821 when it moves and receives the waste material blown out from the machining center 2 during the movement. When one side of the sliding plate 85 moves to be flush with the side of the U-shaped frame 6 near the limiting plate 7, the sliding plate 85... When switch 85 is pressed, the extension rod of hydraulic push rod 84 retracts. The extension rod of hydraulic push rod 84 moves in the opposite direction, causing sliding plate 85 to move in the opposite direction and disengage from switch 88. Switch 88 springs back to its original position. Sliding plate 85 drives sliding plate 86 to move in the opposite direction and reset through connecting frame 87. The waste material on sliding plate 85 will fall onto the receiving frame 821 due to being blocked by the guide frame 5. When sliding plate 85 resets to its initial position, reset spring 83 will spring back and drive the receiving frame 821 to move upward. Switch 89 springs back to its original position.

[0042] Example 2: Based on Example 1, such as Figures 4-5 and Figures 7-8 As shown, the pressing mechanism includes a cylinder 91 fixed to the base frame 1, with two openings on one side of the cylinder 91, the feed port of the cylinder 91 located below the cavity formed by the U-shaped frame 6 and the limiting plate 7, an extrusion frame 92 slidably connected to the cylinder 91, a sliding frame 93 slidably connected to the base frame 1, and a removal component disposed on the sliding frame 93.

[0043] The removal assembly includes a first limiting frame 94 fixed to the sliding frame 93, a second limiting frame 95 slidably connected to the sliding frame 93, one side of the first limiting frame 94 and the second limiting frame 95 respectively blocking the two openings of the cylinder body 91, a second return spring 96 disposed between the second limiting frame 95 and the sliding frame 93, and a contact shaft 97 fixed to the second limiting frame 95. One end of the contact shaft 97 is located in the guide groove of the base frame 1, and the guide groove of the base frame 1 drives the second limiting frame 95 to move by pressing the contact shaft 97.

[0044] The discharge mechanism includes a rack frame 101 slidably connected to the base frame 1, a turntable 102 rotatably connected to the base frame 1, an overrunning clutch 103 fixed to the turntable 102, a gear 104 fixed to the outer ring of the overrunning clutch 103, the rack frame 101 meshing with the gear 104, a drive shaft 105 fixed to the turntable 102, a slot frame 106 fixed to the sliding frame 93, one end of the drive shaft 105 located in the limiting slot of the slot frame 106, and a top rod 107 fixed to the sliding frame 93. The rack frame 101 drives the turntable 102 to rotate through the gear 104 and the overrunning clutch 103, and then drives the sliding frame 93 to move downward through the drive shaft 105 and the slot frame 106.

[0045] Initially, one side of limit frame 94 and limit frame 95 respectively block the two openings of cylinder 91. After the waste material enters the cavity formed by U-shaped frame 6 and limit plate 7, it falls downward into cylinder 91. The movement of sliding plate 85 drives the extrusion frame 92 to move, which in turn drives the rack frame 101 to move. The movement of rack frame 101 drives gear 104 to rotate. Under the action of overrunning clutch 103, turntable 102 does not rotate. Extrusion frame 92 extrudes the waste material that falls into cylinder 91 into blocks. The reverse movement of sliding plate 85 drives extrusion frame 92 to move in the opposite direction. The reverse movement of 92 causes the rack and pinion 101 to move in the reverse direction, which in turn causes the gear 104 to rotate in the reverse direction. Under the action of the overrunning clutch 103, the turntable 102 will rotate. The turntable 102 drives the transmission shaft 105 to rotate, which in turn drives the slot frame 106 to move downward. The downward movement of the slot frame 106 drives the sliding frame 93 to move downward. The sliding frame 93 drives the first limit frame 94, the second limit frame 95, the second return spring 96, and the top rod 107 to move downward. The first limit frame 94 and the second limit frame 95 drive the extruded waste material and the contact shaft 97 downward. After the compressed waste material leaves the cylinder 91, the guide groove of the base frame 1 presses the contact shaft 97 towards the sliding frame 93. The contact shaft 97 drives the limit frame 95 to move to the right while moving downwards. The return spring 96 is stretched, and the top rod 107 presses against the compressed waste material. The limit frame 95 continues to move and disengages from the compressed waste material. Under the action of gravity, the compressed waste material moves downwards and is discharged through the discharge port at the bottom of the housing 3. Through the above operation, the waste material pushed down by the pushing mechanism can be compressed into blocks and discharged. As the disc 102 continues to rotate, it drives the slot frame 106 to move upward via the transmission shaft 105. The upward movement of the slot frame 106 drives the sliding frame 93 to move upward. The sliding frame 93 drives the first limit frame 94, the second limit frame 95, the second return spring 96, and the top rod 107 to move upward. The guide groove of the base frame 1 presses the contact shaft 97 away from the sliding frame 93. The contact shaft 97 drives the second limit frame 95 to move to the left while moving upward. The second return spring 96 rebounds. The first limit frame 94 and the second limit frame 95 continue to move upward and re-block the two openings of the cylinder 91.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
