Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0029] Example 1:

[0030] like Figure 1-7As shown, the notebook shell scrap cutting machine provided by this utility model includes: an operating table 1, a top plate 2 installed above the operating table 1, four guide columns 3 installed between the operating table 1 and the top plate 2, a lifting plate 4 provided between the operating table 1 and the top plate 2, the guide columns 3 penetrating the lifting plate 4, a lower mold 5 installed on the top of the operating table 1, and an upper mold 6 installed at the bottom of the lifting plate 4. The upper mold 6 and the lower mold 5 are respectively adapted to two sides of the notebook shell. A first electric push rod 7 is installed on the top plate 2, and the bottom end of the first electric push rod 7 is connected to the lifting plate 4. A cutting mechanism is provided on the upper mold 6. Multiple cutting mechanisms can be installed according to the number and position of the scrap. The cutting mechanism includes a U-shaped track frame 8 installed on the upper mold 6. A tool holder 9 is slidably mounted on the upper part of the tool holder 9, and a blade 10 is mounted on the bottom of the tool holder 9. A second electric push rod 12 is mounted on the top of the track frame 8. The output shaft at the bottom end of the second electric push rod 12 is connected to the tool holder 9. In use, the laptop shell is placed on the lower mold 5, the first electric push rod 7 is activated, and the lifting plate 4 drives the upper mold 6 to descend, pressing the upper mold 6 onto the top of the laptop shell and fixing the laptop shell between the lower mold 5 and the upper mold 6. The second electric push rod 12 is activated, driving the tool holder 9 to descend along the track frame 8, causing the blade 10 at the bottom of the tool holder 9 to descend and cut off the material on the laptop shell. Then the tool holder 9 and the lifting plate 4 are raised, and the laptop shell on the lower mold 5 is removed and replaced with the laptop shell to be cut.

[0031] By setting up an operating platform 1, a top plate 2, a guide column 3, a lifting plate 4, a lower mold 5, an upper mold 6, and a first electric push rod 7, and setting a cutting mechanism on the upper mold 6, the first electric push rod 7 drives the upper mold 6 to descend, fixing the laptop shell, and the cutting mechanism on the upper mold 6 cuts the material head, which can reduce labor intensity and improve work efficiency.

[0032] Example 2:

[0033] like Figure 5-7 As shown, a slot 13 is provided on the tool holder 9. A connecting block 14, which is adapted to the slot 13 and integrally formed, is installed on one side of the blade 10. A locking knob 11 is installed on one side of the tool holder 9. The end of the locking knob 11 extends into the slot 13 and presses firmly against the connecting block 14, thereby fixing the blade 10. In use, when the blade 10 needs to be replaced, hold the knob 11 and turn it counterclockwise to disengage its end from the connecting block 14. Then, the blade 10 can be pulled down to remove the connecting block 14 from the slot 13, and the new blade 10 can be installed on the tool holder 9.

[0034] The blade 10 can be easily replaced by setting the locking knob 11, the slot 13 and the connecting block 14.

[0035] Example 3:

[0036] like Figure 1-3As shown, a countersunk hole 15 is provided on the lower mold 5, and a push rod 16 is installed in the countersunk hole 15. A cylinder 17 is installed at the bottom of the operating table 1. The cylinder 17 is connected to the bottom end of the push rod 16. In use, after the material head is cut off, the upper mold 6 rises to a certain height, the cylinder 17 is activated, and the push rod 16 is raised to lift the laptop shell from the lower mold 5, so that the laptop shell is separated from the lower mold 5, thus making it easy to remove the laptop shell. After the laptop shell is removed, the push rod 16 descends, and its top is retracted into the countersunk hole 15, and then a new laptop shell can be placed.

[0037] By setting countersunk holes 15, push rods 16, and cylinders 17, the laptop casing can be easily separated from the lower mold 5, facilitating the unloading of the laptop casing.

[0038] Example 4:

[0039] like Figure 3 As shown, the lower mold 5 has multiple ventilation holes 18. After the laptop shell is fastened to the lower mold 5, the ventilation holes 18 allow air to circulate between the top and bottom of the lower mold 5, so that the laptop shell can fully fit the surface of the lower mold 5, making the positioning more accurate. In addition, it can prevent negative pressure from being generated between the laptop shell and the lower mold 5, making it easy to remove the laptop shell from the lower mold 5.

[0040] By setting ventilation holes 18 on the lower mold 5, the loading and unloading of the notebook casing can be facilitated.

[0041] Example 5:

[0042] like Figure 1 and Figure 3 As shown, a discharge hole 19 is provided on the operating table 1, and a discharge groove 20 is provided at the material head position of the lower mold 5. The discharge groove 20 is aligned with the discharge hole 19. After the blade 10 cuts off the material head, the material head falls from the discharge groove 20 and through the discharge hole 19 to the bottom of the operating table 1, thereby preventing the cut material head from accumulating on the top of the operating table 1, which is beneficial for the next notebook shell operation.

[0043] By setting up discharge holes 19 and discharge troughs 20, the cut material ends are discharged through discharge holes 19 and discharge troughs 20 to the bottom of the operating table 1, which can prevent the material ends from accumulating on the operating table 1 and affecting subsequent operations.

[0044] Example 6:

[0045] like Figure 1 As shown, a collection box 21 is provided below the discharge hole 19. The material head falling from the discharge hole 19 falls into the collection box 21 and is collected, which facilitates the subsequent centralized processing of the material head. At the same time, the material head is no longer scattered, which also makes it easier to clean and tidy up the device.

[0046] By setting a collection box 21 below the discharge hole 19, the material head can be easily processed in a centralized manner, which is beneficial to the cleaning and maintenance of the device.

[0047] Working principle: When in use, place the laptop shell on the lower mold 5, activate the first electric push rod 7 to make the lifting plate 4 drive the upper mold 6 to descend, press the upper mold 6 onto the top of the laptop shell, and fix the laptop shell between the lower mold 5 and the upper mold 6. Activate the second electric push rod 12 to drive the cutter holder 9 to descend along the track frame 8, so that the blade 10 at the bottom of the cutter holder 9 descends and cuts off the material on the laptop shell. Then the cutter holder 9 rises and the lifting plate 4 rises, remove the laptop shell from the lower mold 5 and replace it with the laptop shell to be cut.
