Description

Technical Field

[0001] The invention relates to the technical field of burr trimming of plastic portable buckets, in particular to a burr trimming device for a plastic portable bucket. Background Art

[0002] Burrs refer to excess material formed when the plastic melt overflows the edge of the mold due to problems such as loose mold closure and excessive blow molding pressure during the production process of plastic hand buckets. Burrs usually appear at the parting line on the handle and the mouth of the plastic bucket. When removing the burrs on the handle and the mouth of the plastic bucket, the burrs are generally cut off by directly impacting along the edges of the handle and the mouth of the bucket through an impact device. Since the plastic burrs have certain toughness and ductility, after the burrs are cut off by impact, some relatively sharp burrs and burrs will still remain on the handle and the mouth of the bucket. The burrs and burrs remaining on the handle will affect the operator's normal use of the handle to pick up the plastic bucket, and the burrs and burrs remaining on the mouth of the bucket will affect the normal installation of the screw cap on the mouth of the bucket. In the prior art, after the plastic hand bucket is formed and cut off, the remaining burrs and burrs are manually trimmed along the parting line of the handle and the mouth of the bucket by a scraper or an electric grinding tool.

[0003] However, the traditional method of trimming the burrs on the handles and mouths of plastic buckets has the following problems: 1. In the prior art, the trimming of the remaining burrs and burrs generally needs to be carried out after the plastic buckets are unloaded, resulting in the inability to continuously and quickly connect the two-step operation process of breaking the burrs and trimming the burrs, thereby resulting in poor continuity and low efficiency between the overall trimming operations of the plastic buckets; 2. In the prior art, the method of manually trimming the burrs on the handles and mouths of plastic buckets not only has poor consistency in the trimming effect and needs to improve the accuracy, but also may damage the plastic bucket, thereby affecting the overall quality and production and processing costs of the plastic buckets. At the same time, if the number of plastic buckets produced and processed is large, it will lead to a heavy overall burden of manual operation, high labor costs and reduced overall efficiency of the plastic bucket trimming processing.

[0038] See also Figure 3 , Figure 4 and Figure 5 The impact assembly 43 includes a left-right movable impact platform 431 which is elastically slidably arranged on a front-to-back symmetrical spring rod. A handle outer punching groove 432 and a barrel mouth punching groove 433 are opened on the front and back sides of the lower side of the impact platform 431. A handle inner punching block 434 located below the handle outer punching groove 432 is fixed on the right side of the linkage platform 422 through a connecting plate.

[0039] The linkage table 422 is driven to move rightward by the hydraulic cylinder 2 421, and the linkage table 422 then drives the impact table 431 to move rightward synchronously through the connecting rod 1 and the spring rod 1, and drives the handle inner punch block 434 to move rightward synchronously through the connecting plate, until the impact table 431 punches off the corresponding burrs along the outer side of the handle and the outer side of the barrel mouth through the edges of the handle outer punch groove 432 and the barrel mouth punch groove 433 respectively, and the handle inner punch block 434 punches off the burrs on the inner side of the handle, thereby completing the preliminary trimming of the burrs on the handle and the barrel mouth of the plastic barrel 1.

[0040] See also Figure 2 The grinding mechanism 5 includes a connecting platform 51 fixedly arranged on the right side of the linkage platform 422, a docking component 52 is commonly arranged on the connecting platform 51 and the impact component 43, and a grinding component 53 is arranged on the docking component 52.

[0042] See also Figure 2 and Figure 6 The grinding assembly 53 includes a motor 531 fixedly arranged on the upper side of the horizontal section of the L-shaped lifting frame 522, a connecting shaft 532 is fixedly arranged on the driving end of the motor 531, a grinding wheel 533 is fixedly arranged on the outer surface of the connecting shaft 532, and a sealing plug 534 is rotatably arranged on the lower end of the connecting shaft 532.

[0043] When the burrs and burrs remaining at the end of the mouth of the plastic barrel 1 need to be further trimmed and polished, the hydraulic cylinder 421 drives the linkage table 422 and the impact table 431 to continue to move to the right until the impact table 431 is blocked by the positioning baffle 323 and cannot continue to move to the right. At this time, the sealing plug 534 is aligned with the mouth of the plastic barrel 1. Under the continuous drive of the hydraulic cylinder 421, the linkage table 422 drives the connecting table 51 to continue to move to the right and drives the spring rod 1 to continue to press the impact table 431. The connecting table 51 then presses the L-shaped lifting frame 522 downward through the transmission rod 521. The L-shaped lifting frame 522 then moves downward along the slide rail 524 through the slider 523 until the sealing plug 534 is completely inserted into the barrel mouth. , and the lower surface of the grinding wheel 533 is stably attached to the upper end surface of the barrel mouth. At this time, the motor 531 drives the connecting shaft 532 to rotate, and the connecting shaft 532 drives the grinding wheel 533 to grind and trim the burrs and burrs remaining on the upper end surface of the barrel mouth. The sealing plug 534 can ensure that debris will not fall into the plastic barrel 1 from the barrel mouth, so that after the burrs on the barrel mouth are broken, the burrs and burrs remaining on the barrel mouth can be grinded and trimmed, thereby improving the overall continuity and efficiency of the barrel mouth trimming operation. When the impact platform 431 is blocked by the positioning baffle 323, the upper positioning block 324 will be stably docked and inserted into the barrel mouth punching groove 433 to prevent the upper positioning block 324 from obstructing the impact platform 431.

[0046] See also Figure 2 , Figure 7 and Figure 8 The limit assembly 62 includes guide rods 3 621 symmetrically fixed on the upper sides of the driving platform 1 612 and the driving platform 2 615 through the support 4, and a sliding plate 622 that moves forward and backward is slidably arranged on the left and right symmetrical guide rods 3 621, and a guide rod 4 623 is fixedly arranged on the lower side of the left end of the sliding plate 622.

[0047] See also Figure 7 , Figure 8 and Fig. 9 The dressing component 63 includes an outer guide groove 631 and an inner guide groove 632 which are opened on the linkage table 422 from top to bottom and pass through from left to right. A driven shaft 1 633 is slidably arranged in the outer guide groove 631 and the L-shaped slide groove 1 613, and a driven shaft 2 634 is slidably arranged in the inner guide groove 632 and the L-shaped slide groove 2 616. The left ends of the driven shaft 1 633 and the driven shaft 2 634 are respectively slidably connected to the corresponding guide rod 4 623, and the right ends of the driven shaft 1 633 and the driven shaft 2 634 are fixedly arranged with a U-shaped bracket 635, and a motor 2 636 is installed on the inner side of the U-shaped bracket 635. The driving end of the motor 2 636 is fixedly arranged with a grinding brush 637 located on the right side of the U-shaped bracket 635 through a connecting rod 2.

[0048] The electric push rod 611 drives the driving platform 1 612 to move backward, and the driving platform 1 612 then drives the driven shaft 1 633 to move upward along the vertical section of the front end of the outer guide groove 631 through the inclined section of the L-shaped slide groove 1 613, and the left end of the driven shaft 1 633 then moves upward along the corresponding guide rod 4 623, wherein the guide rod 4 623 can ensure that the driven shaft 1 633 does not rotate. At the same time, the driving platform 1 612 and the corresponding sliding plate 622 move forward and backward relative to each other until the driven shaft 1 633 moves to the inclined section on the front side of the outer guide groove 631. At this time, the driven shaft 1 633 also happens to dock with the vertical section of the L-shaped slide groove 1 613. With the continuous driving of the electric push rod 611, the driving platform 1 612 then drives the driven shaft 1 633 to continue to move backward along the outer guide groove 631 through the vertical section of the L-shaped slide groove 1 613 until the driven shaft 1 633 moves to the rear end of the outer guide groove 631.

[0049] During the backward movement of the driving platform 1 612, the connecting frame 614 drives the support 3 and the driving platform 2 615 to move backward synchronously through the spring rod 2, and the driving platform 2 615 first drives the driven shaft 2 634 to move upward along the vertical section at the front end of the inner guide groove 632 through the inclined section of the L-shaped slide groove 2 616, and the left end of the driven shaft 2 634 moves upward along the corresponding guide rod 4 623, wherein the guide rod 4 623 can ensure that the driven shaft 2 634 does not rotate, and at the same time, the driving platform 2 615 and the corresponding sliding plate 622 move forward and backward relative to each other until the driven shaft 2 634 moves to the inclined section at the front side of the inner guide groove 632, at which time the driven shaft 2 634 is just aligned with the L-shaped slide groove 2 616. The vertical sections are docked, and as the driving platform 1 612 continues to move backward, the driving platform 2 615 drives the driven shaft 2 634 to continue to move backward along the inner guide groove 632 through the vertical section of the L-shaped slide groove 2 616, until the driven shaft 2 634 moves to the rear end of the inner guide groove 632. At this time, the driving platform 1 612 can still drive the driven shaft 1 633 to move backward along the outer guide groove 631, and the driven shaft 1 633 is already above the driving platform 2 615 and will not be blocked. Therefore, when the driving platform 2 615 and the driven shaft 2 634 cannot continue to move backward, the driving platform 1 612 can still continue to drive the driven shaft 1 633 to move backward to the rear end of the outer guide groove 631, and at the same time drive the spring rod 2 to continue to press the support 3.

[0050] When the sealing plug 534 is stably inserted into the barrel mouth under the drive of the linkage table 422, the grinding brushes 637 distributed in the front and back are also respectively attached to the outer surface and the inner surface of the handle, and the corresponding grinding brushes 637 are driven by the motor 2 636 to continuously rotate and grind, and the electric push rod 611 drives the driving table 1 612 and the driving table 2 615 to move backward, so that the driving table 1 612 drives the driven shaft 1 633 to move along the outer guide groove 631 matching the outer contour of the handle, and the driving table 2 615 drives the driven shaft 2 634 to move along the inner guide groove 632 matching the inner contour of the handle, and the driven shaft 1 633 drives the corresponding grinding brushes 637 is polished and trimmed along the outer contour of the handle, and the driven shaft 2 634 also drives the corresponding polishing brush 637 to polish and trim along the inner contour of the handle, so that when the grinding wheel 533 polishes and trims the burrs and burrs on the upper end of the barrel mouth, the burrs and burrs on the handle are also polished and trimmed. The above-mentioned operation method not only improves the continuity between the overall finishing operations of the plastic barrel 1 and the efficiency of the overall production and processing, but also can automatically, quickly and stably trim the residual burrs and burrs on the barrel mouth and the handle, thereby improving the consistency and accuracy of the overall finishing effect of the plastic barrel 1, and at the same time greatly reduces the overall manual operation burden.
