DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 6 A material head removal and punching device for plastic parts production includes a processing table 1, on which a punching cylinder 2 is fixedly installed through a bracket, a mounting plate 3 is fixedly installed at the output end of the punching cylinder 2, and a punching knife 5 is fixedly installed on the lower surface of the mounting plate 3. When punching, the plastic part is placed on the processing table 1, and then the punching cylinder 2 is started to drive the punching knife 5 to move vertically downward to achieve punching of the material head on the plastic part.

[0025] A waste trough is provided on the processing table 1, and slide grooves are provided on the inner walls of both sides of the waste trough. A cover plate 6 is provided in the waste trough. A circular hole is provided at one end of the cover plate 6, and a support rod 7 is fixedly installed in the circular hole. Both ends of the support rod 7 are slidably inserted in the slide groove, and an L-shaped support 8 is fixedly installed in the waste trough. The upper surface of the support 8 contacts the lower surface of the cover plate 6, and a metal block 9 is fixedly installed at one end of the cover plate 6 away from the support rod 7. A transmission assembly for driving the metal block 9 to move upward is provided on the mounting plate 3. The transmission assembly includes a mounting rod 10 fixedly installed on the side surface of the mounting plate 3, a spring rod 11 fixedly installed on the mounting rod 10, and a magnet 12 rotatably installed at the lower end of the spring rod 11. The magnet 12 is located directly above the metal block 9. A separation assembly for separating the magnet 12 and the metal block 9 is provided on the processing table 1, and the separation assembly includes two L-shaped limit rods 13 symmetrically fixedly installed on the processing table 1, and the upper end of the limit rod 13 is located above the cover plate 6.

[0026] In the initial state, the cover plate 6 is in a horizontal state, thereby covering the waste trough and facilitating the placement of plastic parts. The support rod 7 on the cover plate 6 is located at one end of the slide slot, and the support 8 supports one end of the cover plate 6. When the punching cylinder 2 drives the punching knife 5 to move vertically downward, the spring rod 11 and the magnet 12 are driven to approach the metal block 9 through the mounting rod 10 until the metal block 9 contacts the magnet 12. During the punching process, the spring rod 11 is compressed, and the punched waste will fall onto the cover plate 6, and then the mounting rod 10 is driven by the punching cylinder 2. The plate 3 moves vertically upwards, at which time the mounting rod 10 drives the magnet 12 to move vertically through the spring rod 11. Under the action of the magnetic force, the magnet 12 drives the metal block 9 to move upwards, and one end of the cover plate 6 is lifted up. At the same time, one end of the mounting support rod 7 of the cover plate 6 moves horizontally along the slide slot, so that the cover plate 6 automatically opens the collection slot. At this time, the waste on the cover plate 6 will fall into the collection slot due to the tilt of the cover plate 6, so as to avoid the waste from accumulating on the processing table 1 and affecting the punching of other plastic parts. At the same time, there is no need for manual cleaning by the staff, which reduces the work intensity.

[0027] When one end of the cover plate 6 contacts the two limit rods 13, the cover plate 6 will be restricted from moving further. At this time, as the magnet 12 continues to move, the magnet 12 will separate from the metal block 9. At this time, under the action of the gravity of the cover plate 6, the cover plate 6 slides along the slide groove and covers the collection groove again.

[0028] A placing plate 14 is fixedly installed on the processing table 1, and a rectangular opening is opened on the placing plate 14. A rotating plate 15 is rotatably installed in the rectangular opening through a rotating shaft. A pulling component for pulling the rotating plate 15 to rotate is provided on the processing table 1. The pulling component includes a lifting block 16 vertically slidably installed on the processing table 1 through a supporting component and a pull rope 17 fixedly installed on the lifting block 16. One end of the pull rope 17 away from the lifting block 16 is fixedly connected to one end of the rotating plate 15 away from the rotating shaft. The lifting block 16 is located above the mounting plate 3. The supporting component includes a support rod 18 fixedly installed on the processing table 1 and a U-shaped slide rail 4 fixedly installed on the support rod 18. The lifting block 16 is slidably sleeved on the U-shaped slide rail 4.

[0029] The placement plate 14 can be used to place plastic parts. When some of the waste materials after punching and cutting fall on the placement plate 14, the punching cylinder 2 will contact the lifting block 16 when driving the mounting plate 3 to move vertically upward, and drive the lifting block 16 to move vertically upward on the U-shaped slide rail 4. At this time, the lifting block 16 will pull one end of the rotating plate 15 through the pull rope 17, and the rotating plate 15 will tilt and rotate through the rotating axis, so that the waste materials will slide onto the cover plate 6. When the punching cylinder 2 drives the lifting block 16 to rise to the uppermost end, the punching cylinder 2 will drive the mounting plate 3 to move vertically downward a short distance. At this time, the lifting block 16 will move to the lowermost end of the U-shaped slide rail 4 under the action of its own gravity, and the rotating plate 15 will rotate to a horizontal state, which is convenient for placing the next plastic part.

[0030] In the utility model, after the punching is completed, the punching cylinder 2 will use the mounting plate 3 to drive the punching knife 5 to move vertically upward. At this time, the metal block 9 is driven upward by the transmission component, and one end of the cover plate 6 is tilted. At the same time, one end of the support rod 7 installed on the cover plate 6 will move horizontally along the slide groove, so that the cover plate 6 will automatically open the collecting groove. At this time, the waste on the cover plate 6 will fall into the collecting groove due to the inclination of the cover plate 6, avoiding the waste from accumulating on the processing table 1 and affecting the punching of other plastic parts. At the same time, there is no need for manual cleaning by the staff, which reduces the work intensity.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
