Technical Field

[0001] This utility model relates to the field of metal packaging can technology, and in particular to a polishing device for the inner and outer walls of a cylindrical metal packaging can. Background Technology

[0002] In the production of cylindrical metal packaging cans, polishing of the inner and outer walls is a critical process. Traditional polishing equipment has several shortcomings: firstly, it is difficult to achieve precise synchronous adjustment of the radial spacing and height of the polishing components for cans of different diameters and heights, resulting in poor polishing uniformity; secondly, inner and outer wall polishing usually requires equipment replacement or complex adjustments, involving frequent manual intervention and low processing efficiency. Furthermore, the debris and dust generated during polishing can easily enter the transmission components, causing equipment wear and affecting its service life.

[0003] Therefore, there is an urgent need for a highly adaptable, automated, stable, and reliable polishing device for the inner and outer walls of cylindrical metal packaging cans to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a polishing device for the inner and outer walls of cylindrical metal packaging cans, which solves the above-mentioned problems.

[0005] This utility model is achieved through the following technical solution:

[0006] A polishing device for the inner and outer walls of a cylindrical metal packaging can includes a base. A transmission groove with a cover is formed in the middle of the upper surface of the base. Four drive grooves are equally spaced around the transmission groove in the direction facing the transmission groove. Each drive groove contains a drive screw and a drive guide rod. A polishing component is fitted onto the drive screw and the drive guide rod. The drive screw in one drive groove passes through the side wall of the drive groove and is connected to a drive motor. The drive screws in all drive grooves pass through the drive groove wall near the transmission groove and enter the transmission groove. Each drive screw has a gear at its end in the transmission groove. All gears mesh in pairs. A column is vertically set next to one drive groove. A horizontal plate is vertically set on the side of the column facing the drive groove and can move up and down. A suction cup rotating component is set on the side of the horizontal plate facing the transmission groove.

[0007] Furthermore,

[0008] The grinding assembly includes a mounting plate and a grinding plate. The mounting plate is mounted on the drive screw and drive guide rod in each drive groove, and the grinding plate is provided on both sides of the mounting plate.

[0009] Furthermore,

[0010] The column also includes a column motor, a column lead screw, and a mounting groove. The mounting groove is vertically opened on the side facing the transmission groove. The column lead screw is installed in the mounting groove and passes through the groove wall and is connected to the column motor on the upper surface of the column.

[0011] Furthermore,

[0012] The horizontal plate is sleeved on the column threaded rod, and the width of the horizontal plate is the same as the width of the mounting groove.

[0013] Furthermore,

[0014] The suction cup rotation assembly includes a cylinder, an extension block, a threaded rod, an air pump, a suction cup, and a bearing. A through hole is opened in the middle of the transmission groove on the horizontal plate, penetrating the upper and lower surfaces. An air pump that seals with the through hole is installed at the through hole on the upper surface. A bearing is fixedly installed at the through hole on the lower surface of the horizontal plate. The threaded rod and the inner ring of the bearing are vertically connected. A suction cup is set at the lower end of the threaded rod. A cylinder is set on the lower surface of the horizontal plate next to the threaded rod, and an extension block is fixedly set on the side of the cylinder output end near the threaded rod. The extension block passes through the threaded rod and matches the thread on the threaded rod.

[0015] Furthermore,

[0016] A sealing layer is provided on both the upper and lower surfaces between the inner and outer rings of the bearing.

[0017] Furthermore,

[0018] The threaded rod has a channel along its central axis.

[0019] The beneficial effects of this utility model are:

[0020] 1. Through the linkage design of gears meshing in pairs in the transmission groove, the lead screws of the four drive grooves can rotate synchronously, ensuring that the polishing components move in a consistent horizontal direction and accurately adjust the radial distance with the can body, thereby adapting to cylindrical metal cans of different diameters and achieving uniform polishing of the inner and outer walls.

[0021] 2. The column motor drives the column screw to move the horizontal plate vertically, and the height of the suction cup rotating assembly can be flexibly adjusted to adapt to metal cans of different heights, significantly expanding the applicability of the device.

[0022] 3. The suction cup rotation assembly uses an air pump to adhere and fix the can body, and the cylinder drives the extension block to cooperate with the threaded rod to drive the can body to rotate at a uniform speed. With the positioning of the grinding plate, full-circumferential automated polishing is achieved, reducing manual intervention and improving processing efficiency.

[0023] 4. Sealing layers are installed on the inner and outer rings of the bearing to effectively prevent debris and dust generated during the polishing process from entering the bearing, reducing the risk of wear, while ensuring the air passage between the air pump and the suction cup is airtight, enhancing the adsorption stability.

[0024] 5. By adjusting the radial position of the grinding components through the drive motor, the same device can quickly switch between inner and outer wall polishing modes without the need to replace equipment or perform complex adjustments, thus reducing operating costs.

[0036] Example

[0037] See Figures 1 to 5 :

[0038] A polishing device for the inner and outer walls of a cylindrical metal packaging can includes a base 1. A transmission groove 6 with a cover is formed in the middle of the upper surface of the base 1. Four drive grooves 2 are equally spaced around the transmission groove 6 in the direction facing the transmission groove 6. Each drive groove 2 is provided with a drive screw 3 and a drive guide rod 4. A polishing component 7 is sleeved on the drive screw 3 and the drive guide rod 4. The drive screw 3 in one drive groove 2 passes through the side wall of the drive groove 2 and is connected to a drive motor 5. The drive screws 3 in all drive grooves 2 pass through the wall of the drive groove 2 closest to the transmission groove 6 and enter the transmission groove 6. Each drive screw 3 has a gear 30 at its end in the transmission groove 6. All gears 30 mesh in pairs. A column 8 is vertically arranged next to one drive groove 2. A horizontal plate 9 is vertically arranged on the side of the column 8 facing the drive groove 2 and can move up and down. A suction cup rotating component 10 is arranged on the horizontal plate 9 facing the transmission groove 6.

[0039] Furthermore,

[0040] The polishing assembly 7 includes a mounting plate 70 and a polishing plate 71. The mounting plate 70 is mounted on the drive screw 3 and drive guide rod 4 in each drive groove 2, and the polishing plate 71 is provided on both sides of the mounting plate 70.

[0041] The mounting plate 70 achieves reciprocating motion to adjust its position via the drive screw 3 and guide rod, and the polishing plates 71 on both sides can be used to polish the inner or outer wall of the cylindrical metal packaging can as needed.

[0042] Furthermore,

[0043] The column 8 also includes a column motor 80, a column lead screw 81, and a mounting groove 82. The mounting groove 82 is vertically opened on the side facing the transmission groove 6. The column lead screw 81 is installed in the mounting groove 82 and passes through the groove wall and is connected to the column motor 80 on the upper surface of the column 8.

[0044] The motor drives the lead screw 3 to rotate, causing the horizontal plate 9 to move vertically, thereby adjusting the height of the suction cup rotating assembly 10 to accommodate cylindrical packaging cans of different heights and improve the versatility of the device.

[0045] Furthermore,

[0046] The horizontal plate 9 is sleeved on the column screw 81, and the width of the horizontal plate 9 is the same as the width of the mounting groove 82.

[0047] The width of the horizontal plate 9 is the same as the width of the mounting groove 82, and it is fitted onto the column screw 81 to ensure that the horizontal plate 9 can only move vertically along the column screw 81, avoiding lateral offset and improving the positioning accuracy and stability of the suction cup rotating assembly 10.

[0048] Furthermore,

[0049] The suction cup rotation assembly 10 includes a cylinder 100, an extension block 101, a threaded rod 102, an air pump 103, a suction cup 104, and a bearing 105. A through hole 12 is opened in the middle of the transmission groove 6, penetrating the upper and lower surfaces of the horizontal plate 9. An air pump 103 is installed at the through hole 12 on the upper surface and is sealed to the through hole 12. A bearing 105 is fixedly installed at the through hole 12 on the lower surface of the horizontal plate 9. The inner ring of the threaded rod 102 and the bearing 105 are vertically connected. A suction cup 104 is provided at the lower end of the threaded rod 102. A cylinder 100 is provided on the lower surface of the horizontal plate 9 next to the threaded rod 102, and an extension block 101 is fixedly provided on the side of the cylinder 100 near the threaded rod 102. The extension block 101 passes through the threaded rod 102 and matches the thread on the threaded rod 102.

[0050] The can is fixed by an air pump 103 and a suction cup 104. A cylinder 100 drives an extension block 101 to move up and down. The extension block 101 passes through a threaded rod 102 and engages with its threads, causing the threaded rod 102 to rotate smoothly on a bearing 105. Simultaneously, the rotation of the threaded rod 102 drives the suction cup 104 at its end to rotate, thus rotating the metal can fixed by the suction cup 104. This process uniformly polishes the inner or outer walls of the metal can, reducing manual intervention.

[0051] Furthermore,

[0052] A sealing layer 11 is provided on both the upper and lower surfaces between the inner and outer rings of the bearing 105.

[0053] A sealing layer 11 (such as a rubber sealing ring) is provided on the upper and lower surfaces of the inner and outer rings of the bearing 105 to prevent metal chips, dust or lubricant generated during the polishing process from entering the interior of the bearing 105, thereby avoiding wear of the bearing 105 and extending the service life of the device. At the same time, the channel from the air pump 103 through the through hole 12 to the central axis of the threaded rod 102 is a closed space when the suction cup 104 fixes the metal packaging can, so that the suction cup 104 can firmly grip the bottom of the metal packaging can.

[0054] Furthermore,

[0055] The threaded rod 102 has a channel along its central axis.

[0056] A channel is opened on the central axis of the threaded rod 102 to connect the air pump 103 and the suction cup 104, forming a closed air passage. This allows the air pump 103 to efficiently draw or fill air through the channel, ensuring that the suction cup 104 can stably adsorb or release the canister, simplifying the pipeline layout and improving the structural compactness.

[0057] The method of using this utility model is as follows:

[0058] In use, first place the metal can on the cover of the drive groove with the bottom facing upwards. Depending on whether the metal can to be polished is the inner or outer wall, drive motor 5 drives one of the drive screws 3 to rotate. Since the gears 30 in the transmission groove 6 mesh in pairs, the drive screws 3 in the four drive grooves 2 rotate synchronously, causing the polishing assembly 7, which is sleeved on the drive screw 3 and drive guide rod 4, to move horizontally (towards or away from the center of the transmission groove 6). Select the corresponding function through the polishing plates 71 on both sides of the mounting plate 70. If polishing the inner wall, move the polishing plate 71 closer to the center of the transmission groove 6; if polishing the outer wall, move the polishing plate 71 slightly away from the center, thereby adjusting the radial distance between the polishing plate 71 and the can.

[0059] After radial position adjustment, the column motor 80 drives the column screw 81 to rotate, causing the horizontal plate 9 to move vertically along the mounting groove 82. This adjusts the height of the suction cup rotating assembly 10, ensuring that the suction cup 104 matches the height of the bottom of the metal can. Then, the air pump 103 is started. The air pump 103 draws air through the channel along the central axis of the threaded rod 102, and the airflow through the sealed air passage formed by the bearing 105 sealing layer 11 causes the suction cup 104 to adhere and fix the bottom of the metal can. At this time, the output end of the cylinder 100 pushes the extension block 101 to move up and down. The threaded engagement between the extension block 101 and the threaded rod 102 causes the threaded rod 102 to rotate within the bearing 105, thereby causing the metal can fixed by the suction cup 104 to rotate at a uniform speed. This, combined with the positioned grinding plate 71, polishes the inner or outer wall of the can during its rotation. The entire device first adjusts the radial position of the polishing component 7 according to the polishing requirements (inner wall / outer wall), then adjusts the height to match the can body, and finally achieves uniform polishing by rotating the suction cup 104. It does not require frequent manual intervention and can efficiently adapt to the polishing requirements of the inner and outer walls of metal cans of different specifications.

[0060] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
