Technical Field
[0001] This utility model relates to the field of processing and trimming, and in particular to a processing and trimming device for plastic tableware. Background Technology
[0002] In the production process of plastic tableware, the edge trimming device trims the edges of the plastic tableware, making the edges smooth and aesthetically pleasing.
[0003] When plastic tableware is produced from the mold, burrs are formed on the edges, affecting its usability. During the edge trimming process, the tableware is placed on a worktable, and a grinding head is activated. The grinding head moves along the edge of the tableware, moving from a support at the top of the worktable to smooth and trim the edges. However, when grinding lighter pieces of plastic tableware, the lack of positional restraints allows the grinding head to move upon contact, affecting the effectiveness of the trimming device. Utility Model Content
[0004] The technical problem this invention aims to solve is that when grinding some lightweight plastic tableware, the plastic tableware is not positioned, causing the grinding head to move after contacting it, which affects the performance of the processing and trimming device.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a plastic tableware processing and trimming device, including a workbench and an installation component. A support is provided on one side of the workbench, and a grinding head is provided on the surface of the support. A limiting device is installed on the workbench with the help of the installation component. The limiting device limits the plastic tableware through a limiting plate and a placement block.
[0006] The effect achieved by the above-mentioned components is as follows: When plastic tableware is produced from the mold, burrs will be generated on the edges, affecting the use of the plastic tableware. Then, when processing and trimming the plastic tableware, the plastic tableware is placed on the worktable, and a limiting device is used to limit the plastic tableware. Then, the grinding head on the worktable is activated, and the grinding head moves at the upper support of the worktable. Then, the grinding head moves along the edge of the plastic tableware to complete the grinding and trimming of the edge of the plastic tableware.
[0007] Preferably, the limiting device includes a placement block, a limiting plate, and a first bolt. Two sliding grooves are formed on the side of the placement block that are close to each other. A sliding block is slidably disposed inside the sliding groove on the surface of the placement block. The sliding block drives the limiting plate to adjust its position. The sliding block is fixed in position to the placement block by the first bolt inserted with internal threads.
[0008] The effect achieved by the above components is as follows: when the plastic tableware is placed on the worktable, it is placed at the corner of the placement block and then moved to slide in the groove on the surface of the placement block. Then, the limiting plate fixed on one side of the sliding block comes into contact with the plastic tableware. Next, the first bolt inside the sliding block is rotated so that one end of the first bolt abuts and fixes against the placement block. Then, the position of the sliding block and the limiting plate is fixed. Finally, the position of the plastic tableware on the worktable is limited. By using the limiting device, the plastic tableware on the worktable surface can be limited, preventing the grinding head from contacting the plastic tableware and causing it to move. This improves the performance of the processing and trimming device.
[0009] Preferably, an operating block is fixed to one side of the first bolt, and the operating block raises the dimension of one side of the first bolt.
[0010] The effect achieved by the above-mentioned components is that, when the first bolt is rotated, the contact area between the first bolt and the operator is increased by the operating block, making it easier for the first bolt to rotate.
[0011] Preferably, arc strips are fixedly installed on both sides of the sliding block near the placement block, and the arc strips reduce the contact area between the sliding block and the groove of the placement block.
[0012] The effect achieved by the above components is that by using arc strips, the contact area between the sliding block and the placement block is reduced, making it easier for the sliding block to move in the groove on one side of the placement block.
[0013] Preferably, an auxiliary component is provided on one side of the placement block.
[0014] The effect achieved by the above components is to increase the friction between the first bolt and the placement block by using auxiliary components, so that the first bolt can better abut against the placement block.
[0015] Preferably, the auxiliary component includes a rubber pad, which is detachably disposed on one side of the placement block, and positioning blocks that are engaged and fixed to the placement block are disposed on both sides of the rubber pad.
[0016] The effect achieved by the above components is that when the rubber pad is bonded and fixed to the placement block, the positioning block is snapped and fixed to the placement block to quickly position the rubber pad and then fix the rubber pad more accurately at the appropriate position on the upper end of the placement block.
[0017] Preferably, the mounting assembly includes a mounting block, a second bolt, and a connecting plate. The mounting block is fixed to one side of the workbench, the connecting plate is inserted inside the mounting block and fixed by the second bolt, and one side of the connecting plate is fixed to the placement block.
[0018] The effect achieved by the above components is as follows: When using the limiting device, the placement block can be moved so that the connecting plate on one side of the placement block can be inserted into the mounting block. Then, the second bolt can be rotated so that the second bolt passes through the mounting block and is threaded to the connecting plate, thus completing the fixing of the placement block position. By using the mounting components, the limiting device can be quickly replaced and installed, so that limiting devices of different sizes can be quickly installed on the workbench surface for use, thereby improving the adaptability of the limiting device.
[0019] Preferably, a washer is abutted on one side of the second bolt, and the washer is located between the second bolt and the mounting block.
[0020] The effect achieved by the above components is that by using shims, the contact area between the second bolt and the mounting block is increased, making the second bolt less prone to loosening and thus improving the performance of the second bolt.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] By using a limiting device, the plastic tableware on the workbench surface can be limited, preventing the grinding head from contacting the plastic tableware and causing it to move, thereby improving the performance of the processing and trimming device.
[0023] By using the mounting components, the limit devices can be quickly replaced and installed, allowing limit devices of different sizes to be quickly installed on the workbench surface for use, thereby improving the adaptability of the limit devices. Attached Figure Description

A support 2 is provided on one side of the worktable 1, and a grinding head 3 is provided on the surface of the support 2. A limiting device 4 is mounted on the worktable 1 via the mounting assembly 5. The limiting device 4 limits the plastic tableware through a limiting plate 44 and a placement block 41. When the plastic tableware is produced from the mold, burrs are generated on the edges, affecting its usability. During the processing and trimming of the plastic tableware, it is placed on the worktable 1, and the limiting device 4 is used to limit its movement. Then, the grinding head 3 on the worktable 1 is activated, moving at the support 2 at the upper end of the worktable 1. The grinding head 3 then moves along the edge of the plastic tableware to complete the grinding and trimming of its edges.
[0033] Figures 1 to 4The limiting device 4 shown includes a placement block 41, a limiting plate 44, and a first bolt 45. Two sliding grooves 42 are opened on the side of the placement block 41 that are close to each other. A sliding block 43 is slidably arranged inside the sliding groove 42 on the surface of the placement block 41. The sliding block 43 drives the limiting plate 44 to adjust its position. The sliding block 43 is fixed to the placement block 41 by the first bolt 45 inserted with internal threads. When placing the plastic tableware on the workbench 1, the plastic tableware is placed at the corner of the placement block 41 and then moved to fit. The sliding blocks 43 at both ends of the placement block 41 are then moved so that the sliding blocks 43 slide in the groove 42 on the surface of the placement block 41. Then, the limiting plate 44 fixed on one side of the sliding block 43 comes into contact with the plastic tableware. Next, the first bolt 45 inside the sliding block 43 is rotated so that one end of the first bolt 45 abuts against and fixes to the placement block 41. Then, the position of the sliding block 43 and the limiting plate 44 is fixed. Finally, the position of the plastic tableware on the workbench 1 is limited. By using the limiting device 4, the plastic tableware on the surface of the workbench 1 can be limited, preventing the grinding head 3 from contacting the plastic tableware and causing it to move. This improves the performance of the processing and trimming device.
[0034] Figures 1 to 4 An operating block 46 is fixedly mounted on one side of the first bolt 45, which raises the dimension of one side of the first bolt 45. When rotating the first bolt 45, the operating block 46 increases the contact area between the first bolt 45 and the operator, making it easier to rotate the first bolt 45. Arc strips 47 are fixedly mounted on both sides of the sliding block 43 near the placement block 41, reducing the contact area between the sliding block 43 and the slide groove 42 of the placement block 41. By using the arc strips 47 to reduce the contact area between the sliding block 43 and the placement block 41, the sliding block 43 can move more easily within the slide groove 42 on one side of the placement block 41.
[0035] Figures 1 to 4 An auxiliary component 48 is provided on one side of the placement block 41. By using the auxiliary component 48, the friction between the first bolt 45 and the placement block 41 is increased, allowing the first bolt 45 to better abut against the placement block 41. The auxiliary component 48 includes a rubber pad 481, which is detachably mounted on one side of the placement block 41. Positioning blocks 482 are provided on both sides of the rubber pad 481 to engage and fix it to the placement block 41. When the rubber pad 481 is adhered and fixed to the placement block 41, the positioning blocks 482 engage and fix it to the placement block 41, quickly positioning the rubber pad 481 and then more accurately fixing it to the appropriate position on the upper end of the placement block 41.
[0036] Figures 1 to 4The mounting assembly 5 shown includes a mounting block 51, a second bolt 52, and a connecting plate 53. The mounting block 51 is fixed to one side of the workbench 1. The connecting plate 53 is inserted into the mounting block 51 and fixed by the second bolt 52. One side of the connecting plate 53 is fixed to the placement block 41. When using the limiting device 4, the placement block 41 can be moved so that the connecting plate 53 on one side of the placement block 41 is inserted into the mounting block 51. Then, the second bolt 52 is rotated so that it passes through the mounting block 51 and is threadedly fixed to the connecting plate 53, thus completing the fixation of the placement block 41. By using the mounting assembly 5, the limiting device 4 can be quickly replaced and installed, allowing limiting devices 4 of different sizes to be quickly installed on the surface of the workbench 1 for use, thereby improving the adaptability of the limiting device 4.
[0037] Figures 1 to 4 A washer 54 is abutting one side of the second bolt 52, which is positioned between the second bolt 52 and the mounting block 51. By using the washer 54, the contact area between the second bolt 52 and the mounting block 51 is increased, making the second bolt 52 less prone to loosening and thus improving its performance.
[0038] Working principle: When plastic tableware is produced from the mold, burrs are generated on the edges, which affects the use of the plastic tableware. Then, when processing and trimming the plastic tableware, the plastic tableware is placed on the worktable 1, and the limit device 4 is used to limit the plastic tableware. Then, the grinding head 3 on the worktable 1 is activated, so that the grinding head 3 moves at the support 2 at the upper end of the worktable 1. Then, the grinding head 3 moves along the edge of the plastic tableware to complete the grinding and trimming of the edge of the plastic tableware. When placing the plastic tableware on the workbench 1, the plastic tableware is placed at the corner of the placement block 41 and then moved to fit. The sliding blocks 43 at both ends of the placement block 41 are then moved so that the sliding blocks 43 slide in the groove 42 on the surface of the placement block 41. Then, the limiting plate 44 fixed on one side of the sliding block 43 comes into contact with the plastic tableware. Next, the first bolt 45 inside the sliding block 43 is rotated so that one end of the first bolt 45 abuts against and fixes to the placement block 41. Then, the position of the sliding block 43 and the limiting plate 44 is fixed. Finally, the position of the plastic tableware on the workbench 1 is limited. By using the limiting device 4, the plastic tableware on the surface of the workbench 1 can be limited, preventing the grinding head 3 from contacting the plastic tableware and causing it to move. This improves the performance of the processing and trimming device.
[0039] When using the limiting device 4, the placement block 41 can be moved so that the connecting plate 53 on one side of the placement block 41 can be inserted into the mounting block 51. Then, the second bolt 52 can be rotated so that the second bolt 52 passes through the washer 54 and the mounting block 51 and is threadedly fixed to the connecting plate 53. Then, the position of the placement block 41 is fixed. By using the mounting assembly 5, the limiting device 4 can be quickly replaced and installed, so that limiting devices 4 of different sizes can be quickly installed on the surface of the workbench 1 for use, thereby improving the adaptability of the limiting device 4.
