Description

Technical Field

[0001] This utility model relates to the field of paper drum processing technology, specifically an automatic edge-rolling device for paper drum processing. Background Technology

[0002] The primary reason for edge grinding on paper drums is to enhance the strength of the top and bottom edges, ensuring structural stability and durability during use. Edge grinding involves creating curved edges at the top and bottom of the drum, allowing the hoops to connect more tightly to the drum body, thus improving the overall strength and load-bearing capacity. Furthermore, edge grinding improves the appearance of the drum, making it more neat and aesthetically pleasing. Edge grinding is an indispensable and crucial step in the paper drum manufacturing process.

[0003] The utility model patent with authorization publication number CN204172431U provides a CNC edge-rolling machine, which also belongs to the field of "paper drum processing" technology. The protected claim is: "A Z-axis drive motor is installed at one end of the machine body. An X-axis drive motor, an X-axis guide positioning slide plate, and a spindle are installed on both the fixed spindle box and the moving spindle box. A paper drum support frame is provided below the forming mold. The paper drum support frame is located between the fixed spindle box and the moving spindle box. The lower end of the paper drum support frame is connected to a vertical positioning push cylinder. The vertical positioning push cylinder is fixed on a sliding guide block. A transverse positioning push cylinder is connected to the side of the sliding guide block. This CNC edge-rolling machine has the characteristics of high production efficiency, simple structure, low cost, and high degree of automation."

[0004] Although the current equipment can perform edge grinding, it is not easy to process multiple paper drums at the same time, resulting in low efficiency. Furthermore, it can only perform edge grinding in one direction. Therefore, we propose an automatic edge grinding equipment for paper drum processing. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0033] Compared with the prior art, the beneficial effects of this utility model are:

[0034] 1. By setting up clamping and edge-grinding components, two second motors are started, which drive two screws to rotate. The two screws drive two lifting blocks to rise and fall synchronously, which in turn drives the lifting plate to rise and fall. This causes multiple pressure caps to press onto multiple paper drums. At this time, the top edge of the paper drum is located between two edge-grinding wheels. Then, a third motor is started, which drives the sun gear to rotate. The sun gear synchronously drives multiple planetary gears to rotate, which in turn drives multiple pressure caps to rotate. The multiple pressure caps drive multiple adjusting components to rotate. At the same time, the adjusting components are activated to clamp the edge of the paper drum, thus edge-grinding the paper drum. Multiple paper drums are edge-grinded simultaneously, improving efficiency.

[0035] 2. By setting up the edge-grinding assembly and the adjustment components inside it, the two electric push rods are activated to push the two sliders to move relative to each other, clamping the edge of the paper drum. While the pressure cap rotates, the two edge-grinding wheels move relative to each other, thus grinding the edge of the paper drum. By adjusting the position of the two edge-grinding wheels, the edge of the drum can be ground inward or outward. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Example 1

[0044] like Figure 1-5 As shown, in this embodiment, an automatic edge-grinding device for paper drum processing includes: a base 1, a clamping assembly 2 fixedly connected to the base 1, and multiple support frames provided at the bottom of the base 1 for raising the device to facilitate operation; an automatic clamp 23 is provided inside the clamping assembly 2 for clamping and fixing the paper drum; and an edge-grinding assembly 3, which is disposed on the base 1 and cooperates with the clamping assembly 2 to perform edge grinding. When the pressure cap 38 rotates, the two edge-grinding wheels 393 move relative to each other, thereby grinding the edges of the paper drum.

[0045] The clamping assembly 2 includes a turntable 21, a base plate 22, and automatic clamps 23. The turntable 21 is rotatably mounted on the base 1. Multiple storage slots 211 are provided on the outside of the turntable 21, and the multiple storage slots 211 are arranged around the central axis of the turntable 21. The base plate 22 is fixedly connected to each of the multiple storage slots 211. The multiple automatic clamps 23 are fixedly connected to the multiple base plates 22 respectively for automatically clamping paper drums. Sensors are provided in each of the multiple automatic clamps 23.

[0046] Specifically, multiple paper drums are placed into multiple automatic clamps 23. Each automatic clamp 23 is equipped with a sensor. When a paper drum is placed into an automatic clamp 23, the automatic clamp 23 immediately clamps and fixes the paper drum in place. Conversely, when the paper drum is pulled upward from the automatic clamp 23, the sensor detects it, and the automatic clamp 23 unfolds and releases the paper drum. In addition, it should be noted that the automatic clamps 23 and the sensors are existing technologies and will not be described in detail.

[0047] Furthermore, such as Figure 2 and Figure 4 As shown, in this embodiment, a first motor 24 is fixedly connected inside the base 1. The drive end of the first motor 24 extends out of the base 1 and is fixedly connected to the bottom of the turntable 21 to drive the turntable 21 to rotate. By setting the first motor 24, the first motor 24 drives the turntable 21 to rotate, which can drive multiple paper drums to revolve. The external conveying equipment, in cooperation with the first motor 24 and the turntable 21, can conveniently perform feeding and discharging.

[0048] Example 2

[0049] like Figure 2 As shown, in this embodiment, the edge-rolling assembly 3 includes: support columns 31, second motors 32, lifting blocks 33, lifting discs 34, planetary carriers 35, third motors 36, planetary gears 37, pressure caps 38, and adjusting components 39. Two support columns 31 are fixedly connected to both sides of the base 1, and each support column 31 has a slot 311. Two second motors 32 are fixedly connected to the tops of the two support columns 31, and screws 321 are fixedly connected to the drive ends of the two second motors 32. The bottom ends of the two screws 321 are rotatably connected to the bottom of the slots 311. Two lifting blocks 33 are respectively disposed in the two slots 311, and are threadedly connected to the two screws 321. The lifting disc 34 is fixedly connected between the two lifting blocks 33. The thread directions of the two screws 321 are the same, and the drive directions of the two second motors 32 are the same, so that the two lifting blocks 33 can be synchronously raised and lowered, i.e., the lifting disc 34 can be raised and lowered.

[0050] Furthermore, such as Figure 2 As shown, in this embodiment, the planetary carrier 35 is fixedly connected inside the lifting plate 34; the third motor 36 is fixedly connected to the planetary carrier 35, and the drive end of the third motor 36 passes through the planetary carrier 35 and is fixedly connected to the sun gear 361; multiple planetary gears 37 are rotatably connected between the planetary carrier 35 and the lifting plate 34, and multiple planetary gears 37 are arranged around the central axis of the sun gear 361, and multiple planetary gears 37 are meshed with the sun gear 361. The rotating ends of multiple planetary gears 37 extend out of the bottom of the lifting plate 34, and the number of multiple planetary gears 37 is the same as that of the storage slot 211 and the automatic clamp 23; multiple pressure caps 38 are respectively fixedly connected to the rotating ends of multiple planetary gears 37, and the inner top surface of multiple pressure caps 38 is provided with a sliding groove 381. The size of multiple pressure caps 38 is larger than the size of the paper drum; multiple adjusting components 39 are respectively fixedly installed on the inner top of multiple pressure caps 38. By adjusting the position of the two edge-grinding wheels 393, the edge of the drum can be adjusted to be rubbed inward or outward.

[0051] Specifically, two second motors 32 are started, driving two screws 321 to rotate. The two screws 321 drive two lifting blocks 33 to rise and fall synchronously, which in turn drives the lifting plate 34 to rise and fall. The lifting plate 34 then descends, causing multiple pressure caps 38 to press onto multiple paper drums. At this time, the top edge of the paper drum is located between two edge-grinding wheels 393. Then, a third motor 36 is started, driving a sun gear 361 to rotate. The sun gear 361 synchronously drives multiple planetary gears 37 to rotate, which in turn drives multiple pressure caps 38 to rotate. The multiple pressure caps 38 drive multiple adjusting components 39 to rotate. At the same time, the adjusting components 39 are activated to clamp the edge of the paper drum, thus grinding the edge of the paper drum.

[0052] Example 3

[0053] Based on Embodiment 2, an adjustment component 39 is provided to adjust the inward or outward rolling of the barrel edge.

[0054] like Figure 4-5 As shown, in this embodiment, the adjusting component 39 includes: an electric push rod 391, a slider 392, and an edge-gripping wheel 393. The electric push rod 391 is fixedly connected to the inner top surface of the pressure cover 38; the slider 392 is slidably connected in the slide groove 381 for limiting movement and preventing deviation from a straight line; the driving end of the electric push rod 391 is fixedly connected to the slider 392; the edge-gripping wheel 393 is rotatably connected to the bottom of the slider 392; the electric push rod 391, the slider 392, and the edge-gripping wheel 393 are configured as two sets, which are arranged opposite to each other; the two edge-gripping wheels 393 are arranged in opposite directions for bidirectional edge-gripping, which can make the paper drum more stable; the two edge-gripping wheels 393 are detachably connected to the inner top surface of the pressure cover 38, so that the directions of the two edge-gripping wheels 393 can be interchanged, thus allowing the paper drum to be edged outwards and inwards.

[0055] Specifically, by activating two electric push rods 391 and precisely controlling their extension and retraction, the corresponding sliders 392 are pushed to move relative to each other along the preset grooves 381 until the sliders 392 clamp the edge of the paper drum. That is, multiple pressure caps 38 rotate smoothly around the axis. At the same time, the two edge-gripping wheels 393 installed in the pressure caps 38 also begin to move relative to each other. During this process, the two edge-gripping wheels 393 contact the edge of the paper drum and produce a rolling and crushing effect, thereby achieving edge-gripping treatment of the paper drum edge. By adjusting the initial position of the two edge-gripping wheels 393, the direction of the drum edge being crushed can be flexibly controlled. When the drum edge needs to be crushed inward, the position of the two edge-gripping wheels 393 can be adjusted appropriately to move them closer to the center of the paper drum; conversely, when crushing outward, they are adjusted to be further away from the center. In summary, this process does not require complex adjustments and can quickly respond to different processing needs.

[0056] Working principle: First, multiple paper drums are placed into multiple automatic clamps 23. Sensors are installed in each clamp 23. When a paper drum is placed in an automatic clamp 23, the clamp immediately holds and secures it. Then, two second motors 32 are activated, driving two screws 321 to rotate. The screws 321 drive two lifting blocks 33 to rise and fall synchronously, thus raising and lowering the lifting plate 34. This causes multiple pressure caps 38 to press onto the paper drums. At this point, the top edge of the paper drum is positioned between two edge-gripping wheels 393. Then, the third motor 36 is started, which drives the sun gear 361 to rotate. The sun gear 361 synchronously drives multiple planetary gears 37 to rotate, which in turn drives multiple pressure caps 38 to rotate. The multiple pressure caps 38 drive multiple adjusting components 39 to rotate. At the same time, the adjusting components 39 are started, and two electric push rods 391 are started, which push two sliders 392 to move relative to each other and clamp the edge of the paper drum. While the pressure caps 38 are rotating, two edge-gripping wheels 393 move relative to each other, which can grind the edge of the paper drum. By adjusting the position of the two edge-gripping wheels 393, the edge of the drum can be ground inward or outward.

[0057] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
