Description

Technical Field

[0001] This utility model relates to the field of laser printing equipment technology, specifically a large-size multi-station laser printing device. Background Technology

[0002] A laser printer is a printing device that uses a laser beam to scan a photosensitive drum to form an electrostatic latent image, and then transfers the image through technologies such as toner adsorption and high-temperature fixing. Most existing laser printers only have one station, which is not convenient for mass production, while those with multiple stations cannot achieve simultaneous loading and printing.

[0003] A novel multi-station laser printer, described in Chinese patent CN216128010U, uses hydraulic rods to allow the laser printhead to be freely adjusted to any position on the surface of the printed product. A transmission device also enables the printhead to move a considerable distance, making it suitable for printing products of varying shapes. While the multi-station printhead design meets the needs of mass production, after printing at each station, the printed object must be removed from the station before a new object is installed. This process interrupts the laser printer's operation, hindering its utilization and reducing production efficiency. Furthermore, placing the object on the worktable is difficult, potentially causing misalignment and affecting the quality of subsequent printed products. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4 As shown, a large-size multi-station laser printing device includes a worktable 1. A stepper motor 11 is fixedly connected to the bottom of the worktable 1. A rotating seat 12 is fixedly connected to the output end of the stepper motor 11 through the outer wall of the worktable 1. Three contact switches 13 are evenly distributed on the top of the worktable 1. A receiving platform 14 is evenly fixedly connected to the outer wall of the rotating seat 12. Mounting plates 15 are symmetrically fixedly connected to the outer wall of the receiving platform 14. Three printing mechanisms 2 are evenly distributed on the top of the worktable 1. A fixing mechanism 3 is provided on the inner wall of the receiving platform 14.

[0025] In this embodiment, the fixing mechanism 3 fixes the objects to be printed on the receiving platform 14 to self-center. Then, the printing mechanism 2 prints the objects. After printing, the stepper motor 11 drives the rotating seat 12 and the receiving platform 14 to rotate, and transfers the second batch of objects to be printed to the printing mechanism 2 for the next printing.

[0026] In an optional embodiment, such as Figure 1 and Figure 2 As shown, there are six receiving platforms 14 evenly distributed in a circular array, which allows the three printing mechanisms 2 to process the objects on the corresponding receiving platforms 14 while the operator can remove the processed objects and place the materials to be processed on the other three receiving platforms 14.

[0027] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the printing mechanism 2 includes three fixed frames 21. The outer wall of the fixed frame 21 is fixedly connected to the motor 22. The output end of the motor 22 is fixedly connected to the lead screw 23. The outer wall of the lead screw 23 is rotatably connected to the inner wall of the fixed frame 21. The outer wall of the lead screw 23 is threadedly connected to the slider 24. The outer wall of the slider 24 is slidably connected to the groove opened on the fixed frame 21. The top of the slider 24 is fixedly connected to the electric push rod 25. The output end of the electric push rod 25 is fixedly connected to the fixed plate 26. The inner wall of the fixed plate 26 is fixedly connected to the multi-stage electric push rod 27. The output end of the multi-stage electric push rod 27 is fixedly connected to the laser housing 28. The bottom end of the laser housing 28 is fixedly connected to the laser print head 29. The motor 22 drives the lead screw 23 to rotate, which drives the slider 24 to move. This causes the slider 24 to drive the electric push rod 25 and the fixed plate 26 to move synchronously. At the same time, the multi-stage electric push rod 27 drives the laser print head 29 to move, so that the laser print head 29 can print at any position of the object.

[0028] In an optional embodiment, such as Figure 2 and Figure 3As shown, the fixed frame 21 is arranged in a circular array, and the center of the array is the same as the center of the array of the receiving platform 14. This ensures that when the rotating seat 12 drives the receiving platform 14 to rotate, it can accurately stop at the position corresponding to the laser print head 29, avoiding any deviation.

[0029] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the stepper motor 11, contact switch 13, motor 22, electric push rod 25, and multi-stage electric push rod 26 are electrically connected via a PLC controller. During the second printing, the worker removes the already printed items and repositions the unprinted items. After placement, the worker presses the contact switch 13. When all three contact switches 13 are pressed, information is sent to the PLC controller, which then sends a command to the stepper motor 11. After the second printing is completed, the stepper motor 11 automatically rotates, causing the next batch of items to be printed to move to the laser print head 29. This achieves the effect of loading and unloading materials while processing, thus accelerating production efficiency.

[0030] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the fixing mechanism 3 includes a first bidirectional lead screw 31 and a second bidirectional lead screw 35. The outer wall of the first bidirectional lead screw 31 is rotatably connected to the inner wall of the mounting plate 15. The outer wall of the first bidirectional lead screw 31 is symmetrically threaded with a first slider 32. The outer wall of the first slider 32 is fixedly connected with a first mounting rod 33. The outer wall of the first mounting rod 33 is symmetrically fixedly connected with a first clamping plate 34. The outer wall of the first clamping plate 34 is slidably connected to a groove opened on the receiving platform 14. Rotating the first bidirectional lead screw 31 drives the first slider 32 to move, so that the first slider 32 drives the first mounting rod 33 and the first clamping plate 34 to move synchronously, thereby enabling the first clamping plate 34 to clamp a pair of opposite sides of the object.

[0031] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the outer wall of the second bidirectional lead screw 35 is rotatably connected to the inner wall of the receiving platform 14. The outer wall of the second bidirectional lead screw 35 is symmetrically threaded with a second slider 36. The outer wall of the second slider 36 is slidably connected to a groove at the bottom of the receiving platform 14. The bottom of the second slider 36 is fixedly connected to a second mounting rod 37. The second mounting rod 37 is slidably connected to a groove at the outer wall of the first mounting rod 33. The outer wall of the second mounting rod 37 is symmetrically fixedly connected to a second clamping plate 38. The outer wall of the second clamping plate 38 is slidably connected to a groove at the receiving platform 14. Rotating the second bidirectional lead screw 35 drives the second slider 36 to move the second mounting rod 37, causing the second mounting rod 37 to move the second clamping plate 38, so that the second clamping plate 38 clamps the other pair of opposite sides of the object, thereby placing the object in the center of the receiving platform 14, which facilitates subsequent printing of the object.

[0032] The above embodiment discloses a large-size multi-station laser printing device. During operation, the object to be printed is evenly placed on the receiving table 14. Then, the first bidirectional lead screw 31 is rotated, driving the first slider 32 to move. This causes the first slider 32 to synchronously move the first mounting rod 33 and the first clamping plate 34, thereby allowing the first clamping plate 34 to clamp a pair of opposite sides of the object. Subsequently, the second bidirectional lead screw 35 is rotated, driving the second slider 36 to move the second mounting rod 37, which in turn moves the second clamping plate 38. The second clamping plate 38 clamps the other pair of opposite sides of the object, thus positioning the object in the center of the receiving platform 14 for easier subsequent printing. Printing can then begin. During printing, the height of the laser print head 29 can be changed via the electric push rod 25. The motor 22 drives the lead screw 23 to rotate, which in turn moves the slider 24. This causes the slider 24 to move the electric push rod 25 and the fixing plate 26 synchronously. Simultaneously, the multi-stage electric push rod 27 drives the laser print head 29 to move, allowing the laser print head 29 to... Printing is performed at any position on the object. After the first printing, the stepper motor 11 is manually started to rotate the rotating base 12 and the receiving platform 14, causing the object to be printed to move to the laser print head 29. Once printed, the object is removed from the laser print head 29, and then the second printing is performed. At the same time, the worker removes the printed object and replaces the unprinted object. After replacement, the contact switch 13 is pressed. When all three contact switches 13 are pressed, information is fed back to the PLC controller, which then sends a signal to the stepper motor 11. When the machine 11 issues a command, after the second printing is completed, the stepper motor 11 automatically rotates, so that the next batch of objects to be printed is moved to the laser print head 29, thereby achieving the effect of loading and unloading while processing, and speeding up production efficiency. In summary, the objects to be printed placed on the receiving table 14 are self-centered and fixed by the fixing mechanism 3, and then the objects are printed by the printing mechanism 2. After printing is completed, the stepper motor 11 drives the rotating seat 12 and the receiving table 14 to rotate, so that the second batch of objects to be printed is moved to the printing mechanism 2 for the next printing.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
