DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0021] Reference Figures 1 to 3 The utility model discloses a plastic barrel trimming device, including a frame 1, two side plates 2 are slidably connected in the frame 1, two cross bars 3 are fixedly connected between the two side plates 2, two electric push rods 4 are fixedly connected to one side of the frame 1, the output end of the electric push rod 4 is fixedly connected to one of the side plates 2, a scraper 5 is fixedly connected to one side of one of the side plates 2, a wedge block 6 is fixedly connected to the upper half of one side of the side plate 2, and the lower half of the wedge block 6 away from the corresponding side plate 2 is inclined, an adjusting plate 7 is arranged in the upper half of the frame 1, the adjusting plate 7 is located between the two wedge blocks 6, a return portion 8 is arranged above the adjusting plate 7, a motor 9 is fixedly connected to the bottom of the adjusting plate 7, and a rotating shell 10 with a bottom opening is transmission-connected to the output end of the motor 9, and a fixing portion 11 is arranged in the rotating shell 10.

[0022] In this embodiment, the top wall and bottom wall of the side panel 2 are respectively fitted with the top wall and bottom wall of the frame 1 to ensure that the side panel 2 does not tilt. The two cross bars 3 are respectively located at the upper and lower halves of the frame 1, so that the two side panels 2 become a whole, so the electric push rod 4 can drive the two side panels 2 to move horizontally synchronously when working.

[0023] The lower half of the side of the wedge block 6 away from the corresponding side plate 2 is gradually inclined from top to bottom and is arranged to point to the corresponding side plate 2 (such as Figure 2 As shown in the figure, when the wedge block 6 moves toward the adjustment plate 7, the inclined side of the wedge block 6 will contact and squeeze the adjustment plate 7, thereby driving the adjustment plate 7 to move downward, and the adjustment plate 7 drives the motor 9, the rotating shell 10 and the fixing part 11 to move downward to fix the plastic barrel.

[0024] In a further preferred embodiment of the present invention, Figure 1 As shown, the return portion 8 includes a plurality of sliding rods 81 fixedly connected to the top of the adjustment plate 7, the sliding rods 81 slide through the top wall of the frame 1, and a top plate 82 is fixedly connected to the top of the sliding rods 81, and a plurality of first springs 83 are fixedly connected between the top plate 82 and the top of the frame 1.

[0025] In this embodiment, the sliding rod 81 passes through the corresponding first spring 83. When the first spring 83 is in a natural state, the adjustment plate 7 is located between the two wedge blocks 6 (such as Figure 1 As shown in FIG. 1 ). When the wedge block 6 moves toward the adjustment plate 7, the adjustment plate 7 is driven to move downward until the bottom surface of the wedge block 6 fits with the top surface of the adjustment plate 7. At this time, the plastic barrel is completely fixed by the fixing portion 11. The wedge block 6 continues to move and will no longer drive the adjustment plate 7 to move downward. The scraper 5 gradually contacts the burrs on the outer wall of the plastic barrel to trim the plastic barrel.

[0026] In a further preferred embodiment of the present invention, Figure 3 As shown, the fixing portion 11 includes a plurality of second springs 111 fixedly connected to the inner top wall of the rotating shell 10, the bottom ends of the plurality of second springs 111 are commonly fixedly connected to a disk 112, a plurality of rotating rods 113 are hingedly connected to the inner top wall of the rotating shell 10, a fixing block 114 is fixedly connected to the bottom end of the rotating rod 113, a plurality of connecting rods 115 are hingedly connected to the outer circumference of the disk 112, and one end of the connecting rod 115 away from the disk 112 is hingedly connected to the corresponding rotating rod 113.

[0027] In this embodiment, when the second spring 111 is in a natural state, the fixing block 114 is completely located in the rotating shell 10. When the rotating shell 10 moves downward, the disc 112 contacts the top surface of the plastic barrel, and then the rotating shell 10 continues to move downward, and the connecting rod 115 and the rotating rod 113 rotate, thereby driving the fixing blocks 114 to tightly squeeze the outer wall of the plastic barrel to fix the plastic barrel.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, a placing table 12 is fixedly connected to the inner bottom wall of the frame 1, and a placing tray 13 with a top opening is rotatably connected to the upper half of the placing table 12. The plastic barrel is placed in the placing tray 13, and the outer peripheral surface of the plastic barrel is in contact with the inner wall of the placing tray 13, and one of the cross bars 3 slides through the placing table 12.

[0029] In this embodiment, before trimming the plastic barrel, the staff places the plastic barrel in the placement tray 13 to position the plastic barrel and ensure that the fixing portion 11 can stably fix the plastic barrel.

[0030] In a further preferred embodiment of the present invention, Figure 3 As shown, an inner support disk 14 is fixedly connected to the center of the bottom of the circular disk 112, and the diameter of the inner support disk 14 is the same as the inner diameter of the plastic barrel.

[0031] In this embodiment, when the second spring 111 is in a natural state, the inner support disk 14 is completely located in the rotating shell 10. When the rotating shell 10 moves downward, the inner support disk 14 is first inserted into the plastic barrel, and then the disc 112 contacts the top wall of the plastic barrel. The inner support disk 14 can support the inside of the plastic barrel to prevent the fixing block 114 from squeezing the plastic barrel too much when fixing the plastic barrel, causing the plastic barrel to deform.

[0032] In a further preferred embodiment of the present invention, Figure 1 As shown, a grinding sheet 15 is fixedly connected to one side of one of the side panels 2 close to the placement table 12 , the grinding sheet 15 and the scraper 5 are located at the same height, and the grinding sheet 15 and the scraper 5 are respectively located on opposite sides of the placement table 12 .

[0033] In this embodiment, after the trimming of the plastic barrel is completed, the electric push rod 4 moves in the opposite direction so that the grinding sheet 15 contacts the plastic barrel, thereby grinding the trimming portion of the plastic barrel, thereby improving the processing quality of the plastic barrel.

[0034] The implementation principle of the above embodiment is:

[0035] Initial state, such as Figure 1 As shown, the first spring 83 and the second spring 111 are both in a natural state, and the wedge block 6 does not contact the adjustment plate 7 .

[0036] The staff puts the plastic barrel in the placement tray 13, and then starts the electric push rod 4 to work. The electric push rod 4 pushes the side plate 2, the wedge block 6 and the scraper 5 to move horizontally. First, the corresponding wedge block 6 squeezes the adjustment plate 7, driving the adjustment plate 7 to move downward until the bottom surface of the wedge block 6 fits the top surface of the adjustment plate 7. In this process, the adjustment plate 7 drives the motor 9, the rotating shell 10 and the fixing part 11 to move downward, the inner support plate 14 is inserted into the plastic barrel, the disc 112 contacts the top surface of the plastic barrel, and then the rotating shell 10 continues to move downward, the connecting rod 115 and the rotating rod 113 rotate, thereby driving several fixing blocks 114 to squeeze the outer wall of the plastic barrel tightly and fix the plastic barrel. At this time, starting the motor 9 can drive the rotating shell 10, the plastic barrel and the placement tray 13 to rotate synchronously.

[0037] The electric push rod 4 continues to work so that the scraper 5 gradually approaches the plastic barrel to trim the plastic barrel.

[0038] After the trimming is completed, the motor 9 stops working, and the electric push rod 4 works in the reverse direction to drive the scraper 5 to move to the original position. The electric push rod 4 continues to work, so that the grinding sheet 15 moves toward the plastic barrel. When the plastic barrel is fixed, the motor 9 works to drive the plastic barrel to rotate, and cooperates with the grinding sheet 15 that contacts the plastic barrel to grind the trimming area.

[0039] After grinding is completed, the electric push rod 4 moves in the opposite direction again to send the grinding disc 15 and the scraper 5 to the initial position. At this time, since the wedge block 6 leaves the adjustment plate 7, the adjustment plate 7 moves upward to its original position under the restoring force of the first spring 83, releasing the fixed state of the plastic barrel, and the staff can remove the plastic barrel.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
