By utilizing the setting of the blade 41 on the holding mechanism 4, the blade 41 can move along with the movement of the holding mechanism 4, and the blade 41 is located directly above the supporting mechanism 3, so that the blade 41 can cut the plastic parts on the supporting mechanism 3, thereby making it convenient for the staff to pry open the plastic parts to observe the bubbles inside the plastic parts, and then judge whether the quality of the plastic parts is qualified.

[0037] Reference Figure 1 The frame 1 includes a guide column 11 and a base 12. The guide column 11 is welded to the base 12. The support block 2 is provided with a hoop on the guide column 11. The support block 2 is provided with a sliding hole 21 and an open groove 22. The sliding hole 21 is connected to the open groove 22. The sliding hole 21 of the support block 2 forms a sliding fit with the guide column 11. The support block 2 is provided with a locking member 23 for locking the open groove 22 on the support block 2. There are two locking members 23. In this embodiment, the locking member 23 is set as a bolt 231, so that the staff can adjust the height of the support block 2 on the guide column 11 by loosening the bolt 231, and then lock the open groove 22 on the support block 2 by tightening the bolt 231, thereby fixing the position of the support block 2 on the guide column 11, thereby driving the driving mechanism 5 and the pressing mechanism 4 to rise and fall.

[0038] Reference Figure 1 and Figure 3 The driving mechanism 5 includes a rotating rod 51 and a driving handle 52. The rotating rod 51 is rotatably connected to the supporting block 2, and the driving handle 52 is welded to one end of the rotating rod 51. Therefore, the staff rotates the driving handle 52 to drive the rotating rod 51 connected thereto to rotate, thereby driving the up and down sliding movement of the holding mechanism 4, providing the necessary power for cutting plastic parts and improving the operating efficiency of the cutting process.

[0039] Reference Figure 3The two ends of the rotating rod 51 are rotatably connected with a rotation damper 511 for slowing down the rotation speed of the rotating rod 51.

[0041] Reference Figure 1 and Figure 2 A lifting hole 24 is provided on the support block 2, and the lifting hole 24 of the support block 2 forms a sliding fit with the driving rod 42. The pressing mechanism 4 includes a connecting member 43 and a storage block 44 for storing the blade 41. The connecting member 43 is detachably arranged on the driving rod 42, and the storage block 44 is detachably arranged on the side of the connecting member 43 away from the driving rod 42, which is convenient for the staff to assemble and disassemble the entire pressing mechanism 4.

[0042] Reference Figure 1 and Figure 2 In this embodiment, a downward-opening mating groove 422 is provided on the end of the driving rod 42 close to the base 12. The mating groove 422 of the driving rod 42 forms an interference fit with the connecting piece 43, and the fixing between the driving rod 42 and the connecting piece 43 is further achieved by the bolt 231. A plug-in groove 431 is provided on the side of the connecting piece 43 away from the driving rod 42. The plug-in groove 431 of the connecting piece 43 forms an interference fit with the storage block 44, and the fixing between the connecting piece 43 and the storage block 44 is further achieved by the bolt 231.

[0043] Reference Figure 1 and Figure 2 The blade 41 is fixed to the inside of the storage block 44 by screws, which makes it easy for the staff to disassemble and replace the blade 41. At the same time, the storage block 44 can separate the blade 41 from the external environment. On the one hand, it protects the blade 41 from wear and tear, and on the other hand, it reduces the risk of the blade 41 accidentally injuring the staff.

[0044] Reference Figure 4A first avoidance groove 441 for avoiding plastic parts is provided on one side of the storage block 44 close to the supporting mechanism 3, so that the storage block 44 can avoid entering the plastic parts during the cutting process, thereby allowing the blade 41 to cut the plastic parts stably.

[0045] Reference Figure 1 and Figure 4 The supporting mechanism 3 includes a connecting plate 31 and a fixing seat 32 for fixing the plastic part. The fixing seat 32 is trapezoidal and cylindrical. The fixing seat 32 is integrally formed on the connecting plate 31. A plug hole 321 is provided on the fixing seat 32. The plug hole 321 of the fixing seat 32 forms a plug-in fit with the plastic part. The fixing seat 32 is symmetrically provided with a second avoidance groove 322 for avoiding the blade 41 at the opening of the plug hole 321, so that the fixing seat 32 can avoid the blade 41 during the cutting process to prevent the blade 41 from colliding with the fixing seat 32 and causing wear.

[0046] Reference Figure 1 and Figure 4 The fixing seat 32 is provided with an adjustment hole 323 near the opening of the plug hole 321. There are two adjustment holes 323 arranged in parallel. The fixing seat 32 is provided with an adjustment bolt 324 corresponding to the position and number of the adjustment holes 323. Any adjustment hole 323 and any adjustment bolt 324 are located below the second avoidance groove 322. When in use, any adjustment bolt 324 forms a threaded connection with the corresponding adjustment hole 323, and any adjustment bolt 324 forms an abutment fit with the side wall of the plastic part in the plug hole 321.

[0047] Reference Figure 1 and Figure 4 The two adjusting bolts 324 are set so that the adjusting bolts 324 can further fix the position of the plastic part. At the same time, the adjusting bolts 324 enable the fixing seat 32 to fix plastic parts of different lengths. When the length of the plastic part is less than the length of the plug hole 321, the staff lifts the plastic part as needed and fixes the plastic part in the plug hole 321 of the fixing seat 32 by screwing the adjusting bolts 324. At the same time, a gap is reserved between the plastic part and the bottom of the plug hole 321, thereby realizing the fixation of plastic parts of different lengths, which is convenient for subsequent cutting operations on plastic parts of different lengths.

[0048] Reference Figure 2 and Figure 4The base 12 is provided with a sliding groove 121, and the connecting plate 31 is symmetrically provided with limiting holes 311. The connecting plate 31 is provided with fixing columns 312 at the positions and numbers corresponding to the limiting holes 311. Since the structures and connection methods of the two fixing columns 312 are the same, one of the fixing columns 312 is taken as an example for explanation. The fixing column 312 is located in the limiting hole 311, and the two ends of the fixing column 312 are respectively threadedly connected with a first nut 313 and a second nut 314. The lower surface of the first nut 313 forms an abutment fit with the upper surface of the connecting plate 31, and the second nut 314 is located in the sliding groove 121 and forms an embedded fit with the sliding groove 121.

[0049] Reference Figure 2 and Figure 4 , by using the setting of the fixing column 312, the first nut 313 and the second nut 314, the staff can loosen the first nut 313 to allow the fixing column 312, the second nut 314 and the connecting plate 31 to slide in the sliding groove 121. Before performing the cutting operation, the staff slides the connecting plate 31 to the edge of the frame 1 to fix the plastic part on the fixing seat 32, and then slides the connecting plate 31 to just below the storage block 44 and tightens it, which improves the operability of the fixing seat 32 and the connecting plate 31, and reduces the possibility of collision of the plastic parts during installation.

[0050] The implementation principle of the embodiment of the present application is as follows: the staff first slides the connecting plate 31 to the edge of the frame 1, adjusts the height of the plastic part in the plug-in hole 321 according to the length of the plastic part to be tested, and then slides the connecting plate 31 to the bottom of the storage block 44, and fixes the connecting plate 31 by tightening the first nut 313. Then the staff operates the driving handle 52 to drive the rotating rod 51 to rotate, thereby driving the driving rod 42 engaged with the driving tooth 53 to move downward, so that the plastic part on the fixed seat 32 smoothly enters the first avoidance groove 441 of the storage block 44. At this time, the blade 41 in the storage block 44 can stably cut the plastic part. After the cutting is completed, the staff takes out the plastic part and manually pries the plastic part apart along the cutting point to observe the bubbles inside the plastic part, and then judge whether the quality of the plastic part is qualified.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
