Description

Technical Field

[0001] This utility model relates to the field of oil drum coloring, and in particular to an oil drum coloring device. Background Technology

[0002] Paints and dyes are typically packaged in plastic or metal drums after production. Depending on the manufacturer and the materials to be packaged, brand and name information needs to be printed on the plastic drums during production.

[0003] In the prior art, patent application number CN202123166485.6 discloses an automatic loading and unloading device for screen printing plastic buckets, including a screen printing machine and a lifting component set at the front end of the screen printing machine. A loading component is set on one side of the screen printing machine, and a pushing component is set on the other side. A unloading component is set between the lifting component and the loading component. The pushing component includes a rodless cylinder, a push rod, and a slide rod. The unloading component includes a rotating seat and a support plate. The push rod, driven by the rodless cylinder, pushes the plastic buckets transmitted by the loading component onto the support plate and cooperates with the lifting component to clamp the plastic buckets. The lifting component drives the plastic buckets to rise, screen prints the plastic buckets through the screen printing machine, and then resets. The push rod, driven by the rodless cylinder, resets and releases the clamp on the screen-printed plastic buckets. At the same time, the slide rod drives the support plate to rotate and unload the plastic buckets. This utility model solves the problems of the prior art, which cannot achieve automatic loading and unloading, requires multiple operators, and results in low processing efficiency, poor continuity, and high labor costs.

[0004] In existing screen printing equipment, the ink drum has poor stability during use, and it is prone to shifting due to inertia or shaking during the coloring process. Therefore, it is necessary to improve the structure to overcome these defects. Utility Model Content

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with the illustrations and specific embodiments.

[0028] like Figures 1 to 2 As shown, the present invention proposes an oil drum coloring device, which includes a conveying unit. The conveying unit is used to provide a conveying trajectory and drive the oil drum to move along the conveying trajectory. The oil drum is conveyed to the coloring station through the conveying unit, thereby realizing the automation and continuity of the coloring process.

[0029] The clamping unit is located on both sides of the conveying unit. The clamping unit is used to clamp and lift the end of the oil drum. When the oil drum moves to the coloring station, it is lifted to a fixed height away from the conveying unit to keep the oil drum stable and prevent the pattern from shifting due to the movement of the oil drum during the coloring process, thus ensuring the coloring accuracy.

[0030] The coloring unit, located above the conveying unit, is used to color the oil drum. The coloring unit includes a mounting bracket 1, which is mounted on the conveying unit and provides support and installation space. A guide rail 2 is mounted on the mounting bracket 1, and a positioning frame 3 is mounted on the guide rail 2. The positioning frame 3 has a groove that matches the guide rail 2, allowing it to move axially along the guide rail 2. A screen printing plate 4 is mounted on the positioning frame 3 and moves synchronously with it. The mounting bracket 1 also includes a screen printing bracket 5, which has a lifting component 6. The lifting end of the lifting component 6 is connected to one end of a connecting plate 7, and the other end of the connecting plate 7 has a screen printing blade 8. The connecting plate 7 has a mounting groove for accommodating the screen printing blade 8, which is positioned within the groove. The lifting component 6 drives the screen printing blade 8 to move up and down, thus printing patterns or text on the surface of the oil drum using screen printing technology.

[0031] In this embodiment, the conveying unit includes a conveying bracket 9, which provides support and installation space; multiple conveying rollers 10 mounted on the conveying bracket 9, which are linked together by a conveyor belt 11; and a speed reducer, one end of which is connected to the conveying rollers 10 and the other end of which is connected to a conveyor motor 12, which provides driving force. The conveyor motor 12 drives the conveying rollers 10 to rotate through the speed reducer, thereby driving the conveyor belt 11 to rotate. Preferably, the surface of the conveyor belt 11 is provided with anti-slip stripes (omitted in the figure). In use, the conveyor motor 12 outputs rotational power, which is transmitted to the conveying rollers 10 after passing through the speed reducer. The conveying rollers 10 drive the conveyor belt 11 to form a continuous cyclic motion. The oil drum is placed at the starting end of the conveyor belt 11 and is driven to move forward. When the oil drum moves to the coloring station, the position sensor 16 detects the oil drum's arrival signal, triggering the conveyor motor 12 to stop. The oil drum is then clamped and lifted by the clamping unit.

[0032] Preferably, baffles 13 are installed on the conveyor belt 11. Multiple baffles 13 are provided and are distributed equidistantly along the conveyor belt 11. The baffles 13 are vertically fixed to the surface of the conveyor belt 11. The oil drum is placed between two adjacent baffles 13. The baffles 13 limit the oil drum and prevent the oil drum from shifting due to inertia.

[0033] Preferably, the conveyor motor 12 is a servo motor or a stepper motor to provide better control accuracy, making the oil drum conveying process more precise and controllable.

[0034] In this embodiment, the clamping unit includes a driving member 14, which provides driving force. Multiple driving members 14 are provided, located on both sides of the conveying unit. A clamping member 15 is also included, with one end connected to the driving end of the driving member 14. The clamping member 15 has a clamping portion matching the oil drum at one end. The driving member 14 drives the clamping member 15 to clamp and lift the oil drum. When the conveyor belt 11 transports the oil drum to the clamping station, the driving member 14 drives the clamping member 15 to rise vertically, lifting the oil drum. After the oil drum is lifted, the driving member 14 remains locked until the coloring unit completes the coloring process. Then, the driving member 14 reverses its direction, causing the oil drum to fall back onto the conveyor belt 11, and the clamping member 15 returns to its initial position. Preferably, the driving member 14 is a hydraulic cylinder.

[0035] A limit plate is provided on the conveying support 9. The limit plate is used to limit the end of the oil drum. A position sensor 16 for detecting the position of the oil drum is also provided on the limit plate. Preferably, the position sensor 16 is a photoelectric head.

[0036] The usage process of this utility model is as follows: During use, the oil drum is placed at the starting end of the conveyor belt 11. The servo motor drives the conveyor roller 10, which moves the oil drum forward via the anti-slip striped conveyor belt 11. The baffle 13 provides lateral restraint to the oil drum, preventing inertial deviation. The position sensor 16 detects that the oil drum has reached the coloring station and triggers the conveyor belt 11 to pause. The drive unit 14 drives the clamping parts 15 on both sides to rise, with the clamping parts adhering to the end of the oil drum, lifting it to a fixed height, detaching it from the conveyor belt 11, and maintaining stability. The positioning frame 3 moves along the guide rail 2 to the designated position, and the screen printing plate 4 aligns with the surface of the oil drum. The lifting unit 6 drives the screen printing knife 8 to press down, printing the pattern / text onto the surface of the oil drum through the screen printing knife 8; after completion, the screen printing knife 8 resets. The clamping unit returns to its initial position, the oil drum falls back onto the conveyor belt 11, the conveyor belt 11 restarts, and the oil drum is sent out of the station to enter the next cycle.
