Abstract
Description
Technical Field
[0001] This utility model relates to the field of burr trimming technology, specifically to a rotary cutter type plastic basket burr trimming machine. Background Technology
[0002] After plastic crates are manufactured, burrs often develop on their edges, affecting the product's appearance and performance, and potentially causing injury to users. Traditional burr trimming methods mostly involve manual repair with blades, which is not only labor-intensive and inefficient, but also poses safety hazards. Some simple trimming equipment is inefficient and unable to effectively remove burrs from plastic crates of different sizes. Therefore, a high-efficiency, precise rotary cutter-type plastic crate burr trimming machine is needed to solve these problems.
[0003] Utility model patent CN216400265U discloses a high-efficiency trimming machine for plastic products, including a worktable with a groove and a slot on the top. A first motor is installed at the center of the bottom of the worktable, and the output end of the first motor is connected to a rotating shaft that extends into the slot. This utility model, by incorporating a third motor, a lead screw, a threaded sleeve, a connecting plate, a slider, and a groove, allows for adjustment of the left and right positions of the trimming blades during plastic product trimming. The operator can activate the third motor via the control panel. The third motor drives the lead screw to rotate, which in turn moves the threaded sleeve. The threaded sleeve then moves the slider within the groove, simultaneously causing the connecting plate to move. This, in turn, moves the trimming blades back and forth to trim different parts of the plastic product. The device can trim plastic products of different sizes and shapes, effectively improving its applicability.
[0004] Although the high-efficiency edge trimming machine for plastic products is convenient for trimming different parts of plastic products of different sizes and shapes, the device still has the following problems in actual use: the movement dimension of the trimming blade is limited, making it difficult to cover the complex edges of plastic baskets, especially with poor adaptability to non-circular, multi-angled basket products. In view of this, we propose a rotary cutter type plastic basket edge trimming machine. Utility Model Content

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.
[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0036] Please see Figures 1-3 A rotary cutter-type plastic basket edge trimming machine includes a base 1. A clamping assembly 2 for limiting the plastic basket whose edges need to be trimmed is slidably connected to the top surface of the base 1. The clamping assembly 2 includes a bidirectional lead screw 21 and two parallel clamping plates 23 threadedly connected to the bidirectional lead screw 21. A mounting frame 3 is fixedly installed on the top surface of the base 1. The mounting frame 3 includes a top plate 32 and several support rods 31 for supporting the top plate 32. A blade-moving assembly 4 is fixedly installed on the bottom surface of the top plate 32. The blade-moving assembly 4 includes two synchronously slidably connected second sliders 45. A connecting block 49 is slidably connected between the two second sliders 45. A vertically downward cylinder 5 is installed on the bottom surface of the connecting block 49. An edge trimming assembly 6 is installed on the bottom surface of the cylinder 5. The edge trimming assembly 6 includes a rotary cutter 63 installed directly above the clamping assembly 2.
[0037] In this embodiment, as Figure 2 As shown, a clamping motor 24 is fixedly installed on one side of the outer wall of the base 1. The output shaft of the clamping motor 24 is coaxially connected to one end of the bidirectional lead screw 21, so that the bidirectional lead screw 21 starts to rotate under the drive of the clamping motor 24.
[0038] Furthermore, such as Figure 1and Figure 2 As shown, the top surface of the base 1 has a sliding groove 11. A blower 7 connected to the sliding groove 11 is fixedly installed on one side wall of the base 1 to facilitate blowing out the waste debris that falls into the sliding groove 11. The clamping assembly 2 also includes two first sliders 22 that are adapted to the size of the sliding groove 11. The two first sliders 22 are respectively threaded to the two sections of the double-acting screw 21 with opposite helical directions. The top surfaces of the two first sliders 22 are respectively fixedly connected to two clamping plates 23. When the double-acting screw 21 rotates, the two first sliders 22 drive the clamping plates 23 to move synchronously in opposite directions to achieve clamping or loosening of the plastic basket.
[0039] Furthermore, such as Figure 3 As shown, two first slide rails 41 are installed side by side on the bottom surface of the top plate 32. Limiting blocks 411 are fixedly installed at both ends of the first slide rails 41 to limit the two second sliders 45 and prevent the second sliders 45 from sliding out of the first slide rails 41. A first lead screw 42 and a slide rod 43 are respectively rotatably engaged between the two limiting blocks 411 on the two first slide rails 41. One of the second sliders 45 is threadedly connected to the first lead screw 42, and the other second slider 45 is slidably connected to the slide rod 43, so that the first lead screw 42 and the slide rod 43 can rotate under the restriction of the limiting blocks 411 to drive the second slider 45 to slide.
[0040] It is important to note that, such as Figure 3 As shown, a first motor 44 is fixedly installed on the bottom surface of the top plate 32. The output shaft of the first motor 44 is coaxially connected to one end of the first lead screw 42, which can drive the first lead screw 42 to rotate. The second slider 45, which is threadedly connected to the first lead screw 42, starts to slide and drives another second slider 45 to slide along the first slide rail 41 through the second slide rail 46.
[0041] In this embodiment, as Figure 3 As shown, a second slide rail 46 is installed between the two second sliders 45, and a second lead screw 47 is rotatably inserted between the two second sliders 45. The second lead screw 47 is threadedly connected to the connecting block 49, and the connecting block 49 is slidably connected to the second slide rail 46. The rotation of the second lead screw 47 drives the connecting block 49 to slide on the second slide rail 46.
[0042] Furthermore, such as Figure 3 As shown, a second motor 48 is fixedly installed on the outer wall of one of the second sliders 45. The output shaft of the second motor 48 is coaxially connected to one end of the second lead screw 47. The second motor 48 can drive the second lead screw 47 to rotate, thereby driving the connecting block 49, the cylinder 5 and the trimming assembly 6 to slide horizontally.
[0043] It is worth mentioning that, such as Figure 3As shown, the trimming assembly 6 also includes a trimming motor 61 installed at the end of the telescopic rod of the cylinder 5. The output shaft of the trimming motor 61 is coaxially connected to a rotating shaft 62. The bottom end of the rotating shaft 62 is coaxially fixedly connected to the rotating cutter 63. The trimming motor 61 drives the rotating shaft 62 to drive the rotating cutter 63 to rotate at high speed. In conjunction with the movement of the blade moving assembly 4 and the cylinder 5, the rough edges of the plastic basket are cut and trimmed.
[0044] Finally, it should be noted that the clamping motor 24, the first motor 44, the second motor 48, the cylinder 5, the trimming motor 61, the blower 7, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.
[0045] Working principle: When using the rotary cutter plastic basket edge trimming machine of this embodiment, the plastic basket to be trimmed is first placed between the two clamping plates 23 of the clamping assembly 2. The clamping motor 24 drives the bidirectional lead screw 21 to rotate, so that the two first sliders 22 threadedly connected to the bidirectional lead screw 21 slide along the slide groove 11 of the machine base 1, driving the clamping plates 23 to move closer to each other to clamp the plastic basket.
[0046] The position of the rotary cutter 63 is then adjusted by the blade shifting assembly 4: the first motor 44 drives the first lead screw 42 to rotate, causing the second slider 45 to slide along the first slide rail 41, which in turn moves the second slide rail 46 to adjust the lateral position; the second motor 48 drives the second lead screw 47 to rotate, causing the cylinder 5 to slide along the second slide rail 46 to adjust the longitudinal position; and the cylinder 5 extends and retracts to adjust the height of the rotary cutter.
[0047] During trimming, the rotating cutter 63 of the trimming assembly 6 rotates under the drive of the trimming motor 61 to trim the rough edges of the plastic basket. At the same time, the blower 7 blows air into the chute 11 to clean up the debris that falls into the chute 11 during the trimming process.
[0048] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
