Description

Technical Field

[0001] This utility model relates to the field of steel drum printing technology, specifically to a two-color steel drum printing device. Background Technology

[0002] Steel drums, as efficient packaging containers, are widely used for the transportation and storage of liquid, solid, and semi-solid products. Before use, labels are usually printed on the outer wall of steel drums to identify the contents. Currently, screen printing is the main technology for printing on the outer wall of steel drums.

[0003] The prior art discloses (Publication No.: CN100577420C) an automatic multi-color screen printing machine for steel drums. Its key technical features include conveying devices fixed at the front and rear ends of the printing frame, a printing mechanism located directly above the frame, a positioning gear device fixed at the rear of the frame, a lifting worktable fixed below the frame, and a drying device located directly above the rear conveyor frame. With this structure, the steel drum is conveyed from the front conveyor frame to the printing position. The lifting worktable lifts the drum, and after the positioning cylinder locates the oil filling port and secures the drum body to the large gear, it is driven by the same cylinder to complete the printing process, synchronizing the screen movement with the drum body rotation. This ensures the accuracy of multi-color registration. The advantages of this invention include good registration accuracy, stable color, fast production speed, and suitability for industrial production.

[0004] However, existing technology can only print multiple colors on different axes of the same steel drum, but cannot print different colors or different text on the same axis of the steel drum. This requires the steel drum to be printed twice in order to achieve printing different colors or different text on the same axis, which greatly reduces the efficiency of steel drum printing. To address this problem, we have proposed a two-color steel drum printing device. Utility Model Content

[0005] The present invention aims to provide a two-color steel drum printing equipment to solve the problem that the existing technology cannot print different colors or different texts on the same axis of the steel drum, which greatly reduces the printing efficiency of the steel drum.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a two-color steel drum printing device, comprising a conveyor frame for conveying steel drums, an mounting frame at one end of the conveyor frame, and a printing assembly at the mounting frame. The printing assembly includes a guide rail, a printing frame, a first driving component, and two sets of printing components. The guide rail is located at the end of the mounting frame away from the conveyor frame, the printing frame is located inside the mounting frame, and a first printing area and a second printing area are formed inside the printing frame. The first driving component is located between the mounting frame and the printing frame, and can drive the printing frame to move. The two sets of printing components are symmetrically arranged at the end of the guide rail away from the conveyor frame. Each printing component includes a slider, a second driving component, a connecting block, a cylinder, and a scraper. The slider is located at the end of the guide rail away from the mounting frame, the second driving component is located between the slider and the guide rail, and can move the slider on the guide rail. The connecting block is located at the end of the slider close to the conveyor frame, the cylinder is located at the end of the connecting block, and the scraper is located at the output end of the cylinder. Each scraper can abut against the corresponding first and second printing areas.

[0007] The beneficial effects of this solution are as follows: By opening a first printing area and a second printing area within the printing frame, different text or colors can be set in the first and second printing areas respectively. The mounting frame is used to install the printing components, and the first driving component is used to drive the printing frame to reciprocate. When the printing frame moves, it can drive the steel drum that it abuts to rotate, thereby cooperating with the scraper to scrape the ink in the printing frame, so that the text in the printing frame is printed on the outer wall of the steel drum. During use, the conveyor frame transports the steel drum to below the printing station, and the edge of the steel drum abuts against the lower end of the printing frame. At this time, the first set of scrapers and the second set of scrapers are both in the initial positions of the first and second printing areas, and the first set of scrapers is above the printing station. The first set of scrapers abuts against the first printing area under the action of the corresponding cylinder. At this time, the first set of printed parts does not move, while the second set of printed parts moves synchronously with the printing frame and remains relatively stationary. When the end of the first printing area moves to below the first set of printed parts, the scraper of the first set separates from the first printing area under the action of the corresponding cylinder. At the same time as the first set of printed parts separates from the first printing area, the first... The first set of printed parts moves along the printing frame and remains relatively stationary. When the second set of squeegees moves to the printing station above the steel drum to be printed, the second drive unit of the second set stops moving, and under the action of the corresponding cylinder, the squeegee of the second set abuts against the second printing area. As the printing frame continues to move, the text in the second printing area is printed on the outer wall of the steel drum. When the end of the second printing area moves below the second set of printed parts, the squeegee of the second set separates from the second printing area under the action of the corresponding cylinder. At this point, the first steel drum is printed, and the second set is printed. The squeegee of the second set of printed parts is located on the printing station. When the next steel drum to be printed is conveyed to the printing station by the conveyor, the squeegee of the second set of printed parts comes into contact with the second printing area under the action of the corresponding cylinder. At this time, the moving direction of the printing frame and each printed part is opposite to the printing direction of the first steel drum. After the printing of the second steel drum is completed, the printed parts of the first set will be placed back on the printing station, thus repeating the above operation. Different texts and colors can be printed on the same axis of the steel drum, which can reduce the number of printing steps and increase the efficiency of steel drum printing.

[0008] Preferably, as an improvement, the first driving component includes a first motor, a first gear, and a first rack. The first motor is located at one end of the mounting bracket, the first gear is located at the output end of the first motor, and the first rack is located at the end of the printing frame near the guide rail, and the first gear meshes with the first rack.

[0009] The beneficial effect is that by setting the first rack at one end of the printing frame near the mounting frame, and cooperating with the first gear at the output end of the first motor, the printing frame can be moved by starting the motor.

[0010] Preferably, as an improvement, the second driving component includes a second motor, a second gear, and a second rack. The second motor is located at the end of the slider away from the guide rail, and the output end of the second motor passes through the slider. The second gear is located at the output end of the second motor, and the second rack is located on the inner wall of the guide rail, and the second gear meshes with the second rack.

[0011] The beneficial effect is that by starting the second motor, the second gear is driven to rotate, thereby causing the second gear to move along the second rack that meshes with it, and thus driving the slider to move on the outer wall of the guide rail.

[0012] Preferably, as an improvement, the printing frame is provided with pressure strips symmetrically at one end near the conveyor frame, and the pressure strips can abut against the edge of the steel barrel, and several springs are provided between the pressure strips and the printing frame.

[0013] The beneficial effects are as follows: by setting a pressure strip at the lower end of the printing frame, the friction between the printing frame and the steel barrel is increased, preventing the steel barrel from slipping and causing misprints. By setting several springs between the pressure strip and the printing frame, not only can the impact force on the printing frame when the steel barrel and the pressure strip come into contact be reduced, but the pressure strip can also make the contact between the pressure strip and the edge of the steel barrel more tight, further preventing the steel barrel from slipping.

[0014] Preferably, as an improvement, the slider is U-shaped, with the opening of the slider facing the end closest to the printing frame, and through slots are symmetrically opened on the side wall of the slider.

[0015] The beneficial effects are as follows: by setting the slider to a U-shape, the slider is partially wrapped around the outer wall of the guide rail, which increases the stability of the slider when it moves. By opening through grooves on the side wall of the slider, the weight of the slider can be reduced, and the wear between the second gear and the second rack can be reduced.

[0016] Preferably, as an improvement, the second motor is located on the side of the slider closer to the receiver, and the cylinder is located on the end of the connecting block away from the receiver.

[0017] The beneficial effects are: by placing the second motor and the cylinder on both sides of the slider, the slider is subjected to more even force, making the slider move more smoothly.

[0018] Preferably, as an improvement, the pressure strip is made of an elastic rubber material.

[0019] The beneficial effects are as follows: by setting the pressure strip to an elastic rubber material, the friction between it and the steel drum can be increased, preventing the steel drum from slipping. At the same time, the rubber material can also absorb the kinetic energy of the steel drum hitting the pressure strip, thereby protecting the printing frame. Attached Figure Description

[0027] Example

[0028] The basic implementation examples are as follows: Figure 1-5 As shown, Figure 1 The illustrated two-color steel drum printing equipment includes a conveyor frame for conveying steel drums 20. A mounting frame 1 is fixedly installed on the upper end of the conveyor frame. The mounting frame 1 is equipped with a printing assembly, which includes a guide rail 2, a printing frame 3, a first drive component, and two sets of printing components. The guide rail 2 is fixedly installed on the upper end of the mounting frame 1. The front and rear inner walls of the mounting frame 1 are symmetrically provided with sliding grooves, and the printing frame 3 is slidably installed within these grooves. Figure 2The printing frame 3 shown has several connectors 17 symmetrically slidably installed on its front and rear sides. A limit block is fixedly installed on the upper end of each connector 17. A pressure strip 16 is fixedly installed on the lower end of each connector 17 on the same side. The pressure strip 16 can abut against the edge of the steel barrel 20. The pressure strip 16 is made of elastic rubber material. Several springs 18 are provided between the pressure strip 16 and the printing frame 3. Each spring 18 is sleeved on the outer wall of each connector 17. The printing frame 3 has a first printing area 4 and a second printing area 5 opened from left to right. A first driving component is located between the conveyor frame and the printing frame 3. The first driving component includes a first motor 12, a first gear 13 and a first rack 14. The first motor 12 is fixedly installed on the upper rear side of the mounting frame 1. The first gear 13 is fixedly installed on the output end of the first motor 12. The first rack 14 is fixedly installed on the upper rear side of the printing frame 3. The first gear 13 and the first rack 14 mesh. The first driving component can drive the printing frame 3 to reciprocate within the mounting frame 1.

[0029] Two sets of printed parts are symmetrically arranged at the end of guide rail 2 away from the conveyor frame, such as... Figure 1 and Figure 3 The printed component shown includes a slider 6, a second driving component, a connecting block 7, a cylinder 8, and a scraper 9. The slider 6 is slidably mounted on the upper end of the guide rail 2. The slider 6 is U-shaped, with its opening facing downwards and encasing the outer wall of the guide rail 2. Several through slots 19 are symmetrically opened on the side wall of the slider 6. The second driving component is located between the slider 6 and the guide rail 2. The second driving component includes a second motor 15, a second gear, and a second rack. The second motor 15 is fixedly mounted on the upper end of the slider 6, and its output end extends through the slider 6 to the space between the slider 6 and the guide rail 2. The second gear is fixedly installed at the output end of the second motor 15, the second rack is fixedly installed on the inner wall of the guide rail 2, and the second gear meshes with the second rack. The second driving component can drive the slider 6 to move on the guide rail 2. The connecting block 7 is fixedly installed at the lower end of the slider 6, and the cylinder 8 is fixedly installed at the end of the connecting block 7 away from the second motor 15, so that the cylinder 8 and the second motor 15 are not located on the same side of the slider 6. The scraper 9 is fixedly installed at the output end of the cylinder 8, and each scraper 9 can abut against the corresponding first printing area 4 and second printing area 5.

[0030] The specific implementation process is as follows:

[0031] During production, the conveyor belt transports the steel drum 20 to be printed to the area below the printing station. Once the steel drum 20 is below the printing station, the lifting platform below the conveyor belt lifts the steel drum 20 until the edges of both ends of the steel drum 20 abut against the pressure strip 16 at the bottom of the printing frame 3. At this time, both the left and right scrapers 9 are in their initial positions in the first printing area 4 and the second printing area 5, with the left scraper 9 directly above the steel drum 20. Subsequently, the left scraper 9, under the action of the corresponding cylinder 8, abuts against the first printing area 4. Figure 4 As shown, at this time, the first driving component drives the moving frame to move to the left, thereby causing the steel barrel 20 to rotate. At this time, the printed part on the left does not move and remains relatively stationary with respect to the steel barrel 20 to be printed, while the printed part on the right moves synchronously with the printing frame 3 and remains relatively stationary. When the end position of the first printing area 4 moves to below the left scraper 9, the left scraper 9 separates from the first printing area 4 under the action of the corresponding cylinder 8. At the same time as the left scraper 9 separates from the first printing area 4, the printed part on the left moves along the moving direction of the printing frame 3. While remaining relatively still, when the right scraper 9 moves to the printing station above the steel drum 20 to be printed, the second drive component on the right stops moving, and under the action of the corresponding cylinder 8, the right scraper 9 comes into contact with the starting position of the second printing area 5. As the printing frame 3 continues to move to the left, the text of the second printing area 5 is printed on the outer wall of the steel drum 20. When the ending position of the second printing area 5 moves to below the right scraper 9, the right scraper 9 separates from the second printing area 5 under the action of the corresponding cylinder 8. At this time, the first steel drum 20 has completed printing.

[0032] At this time, the scraper 9 of the second set of printed parts is located on the printing station. When the next steel drum 20 to be printed is conveyed to the area below the printing station by the conveyor frame, the scraper 9 on the right side, under the action of the corresponding cylinder 8, comes into contact with the end position of the second printing area 5. Figure 5 As shown, at this time, the printing frame 3 moves to the right. After repeating the above operation, the printed part on the left will be back on the printing station. The scrapers 9 on the left and right sides are both above the starting positions of the first printing area 4 and the second printing area 5. By repeating the above operation, different texts and colors can be continuously printed on the same axis of the steel drum 20, which can reduce the printing process of the steel drum 20 and improve the printing efficiency of the steel drum 20.
