Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laser marking equipment technology, specifically relating to an integrated device for laser micro-engraving traceability codes on selenium-enriched eggshells. Background Technology
[0002] Currently, laser marking equipment for selenium-enriched eggs typically uses the following structure to achieve micro-engraving of traceability codes:
[0003] Egg tray conveying system: The egg tray containing the eggs is placed on the tray, and the tray is moved intermittently by a stepper motor, so that each egg passes through the laser marking station in turn.
[0004] Laser marking mechanism: It adopts a galvanometer laser and uses a reciprocating marking head to micro-engrave the surface of the eggshell.
[0005] However, existing technologies have the following key drawbacks:
[0006] The trays were heavily contaminated and difficult to clean.
[0007] Egg trays are usually made of paper, which makes them prone to crumbling during transport.
[0008] Eggs may have feces, feathers, or other dirt on their surface, which can accumulate as dirt when they fall onto a tray.
[0009] Most existing pallets are fixed with bolts, and disassembly requires tools, which affects the efficiency of continuous production line operation.
[0010] Lack of self-locking and fast unlocking mechanisms:
[0011] Traditional trays rely solely on screws for fastening and cannot utilize the weight of the egg tray itself to achieve automatic locking.
[0012] Even after removing the egg tray, the screws still need to be loosened manually, making it impossible to achieve the convenient "remove tray and unlock" operation.
[0013] To address the aforementioned issues, a selenium-enriched eggshell laser micro-engraving traceability code integrated device is provided.
[0014] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0015] The purpose of this invention is to provide an integrated device for laser micro-engraving traceability codes on selenium-enriched eggshells, in order to solve the problem that the lack of self-locking and quick unlocking mechanisms in the existing technology leads to inconvenience in disassembly and cleaning when the tray is heavily contaminated.
[0016] To achieve the above objectives, this utility model provides the following technical solution:
[0017] A selenium-enriched eggshell laser micro-engraving traceability code integrated device includes a machine base. An n-shaped support frame is fixedly connected to the top of the machine base near its rear side wall. A laser marking head is connected to the n-shaped support frame through a reciprocating transmission mechanism. A tray is set below the laser marking head. A stepping moving mechanism installed on the top of the machine base is also provided at the bottom of the tray. A gravity self-locking positioning component is connected between the stepping moving mechanism and the bottom of the tray.
[0018] Preferably, the stepping movement mechanism includes a sliding seat slidably connected to the center of the top of the machine base. The vertical cross-section of the sliding seat is convex. An I-shaped base plate is fixedly connected to the top of the sliding seat. The I-shaped base plate is slidably sleeved on the outside of two symmetrically arranged guide rails. The vertical cross-section of the guide rails is also I-shaped. The sliding seat is slidably connected to a sliding groove opened at the top of the machine base. A screw is threaded onto the sliding seat. Both ends of the screw are rotatably connected to the sliding groove. The rear end of the screw extends to the rear side of the machine base and is fixedly connected to the output shaft of the stepper motor.
[0019] Preferably, the gravity self-locking positioning component includes two symmetrically arranged inserts fixed to the bottom of the tray, the top of the I-shaped base plate is provided with a slot that mates with the inserts, the bottom of the inserts is provided with two symmetrically arranged first inclined surfaces, and the first inclined surfaces away from the middle of the I-shaped base plate are movably overlapped with the second inclined surface provided on the top of the L-shaped pressing strip.
[0020] Preferably, the two L-shaped pressing bars are symmetrically arranged, and each L-shaped pressing bar is movably inserted into an L-shaped groove opened in the inner wall of the slot. Each L-shaped pressing bar has two symmetrically arranged third inclined surfaces at the end away from the second inclined surface.
[0021] Preferably, each of the inserts is provided with a limiting plate fixed to the bottom of the tray on one side. The limiting plate is movably attached to the outside of the I-shaped base plate. A slot is provided on the side wall of the limiting plate that is movably attached to the outside of the I-shaped base plate.

[0022] Preferably, the side wall of the L-shaped pressing strip facing the slot is fixed to the inner wall of the L-shaped slot by multiple springs, and the springs are made of carbon steel.
[0023] Compared with the prior art, the present invention has the following beneficial effects:
[0024] (1) The integrated laser micro-engraving traceability code device for selenium-enriched eggshells of this utility model can be used to laser micro-engraving traceability codes on multiple selenium-enriched eggs on an egg tray. The egg tray can be manually placed on the tray, and the tray will move down two inserts and two limiting plates under the weight of the egg tray and multiple eggs. The first inclined surface at the bottom of the insert will press against the second inclined surface at the top of the L-shaped pressing strip, and the L-shaped pressing strip will press against multiple springs. One end of the two third inclined surfaces on the L-shaped pressing strip will move outward until it is inserted into the slot opened on the limiting plate. Thus, with the help of the weight of the egg tray and multiple eggs, the tray and the I-shaped base plate can be self-locked and fixed, which can ensure the stability during the intermittent backward movement. In addition, after the multiple eggs on the marked egg tray are removed, the spring will return to its original position under the action of the second inclined surface, which will push the insert up and make the tray easy to remove for cleaning without removing the screws to achieve the purpose of disassembly and fixing.

[0034] Tray 3 is heavily contaminated and difficult to clean.
[0035] Egg trays are usually made of paper, which can easily generate debris such as paper scraps and eggshell dust during transportation.
[0036] The surface of the eggs may have residual feces, feathers and other dirt, which will accumulate when they fall onto tray 3.
[0037] The existing pallets are mostly fixed with bolts, and disassembly requires tools, which affects the efficiency of continuous operation of the production line.
[0038] Lack of self-locking and fast unlocking mechanisms:
[0039] Traditional tray 3 relies solely on screws for fastening and cannot utilize the weight of the egg tray itself to achieve automatic locking.
[0040] Even after removing the egg tray, the screws still need to be loosened manually, making it impossible to achieve the convenient "remove tray and unlock" operation.
[0041] See attached document Figure 1-4 A selenium-enriched eggshell laser micro-engraving traceability code integrated device includes a machine base 1. An n-shaped support frame 11 is fixedly connected to the top of the machine base 1 near its rear side wall. A laser marking head 13 is connected to the n-shaped support frame 11 through a reciprocating transmission mechanism 12. A tray 3 is set below the laser marking head 13. A stepping moving mechanism 2 installed on the top of the machine base 1 is also provided at the bottom of the tray 3. A gravity self-locking positioning component 4 is connected between the stepping moving mechanism 2 and the bottom of the tray 3.
[0042] The reciprocating transmission mechanism 12 is existing technology. It uses a motor to drive the reciprocating screw to rotate, and causes the guide seat to drive the laser marking head 13 to reciprocate on the guide rail 23. The specific details will not be described in detail.
[0043] Furthermore, such as Figure 1-4 As shown, the stepping movement mechanism 2 includes a sliding seat 21 slidably connected to the middle of the top of the machine base 1. The vertical cross-section of the sliding seat 21 is convex. An I-shaped base plate 22 is fixedly connected to the top of the sliding seat 21. The I-shaped base plate 22 is slidably sleeved on the outside of two symmetrically arranged guide rails 23. The vertical cross-section of the guide rails 23 is I-shaped. The sliding seat 21 is slidably connected to a sliding groove opened at the top of the machine base 1. A screw 24 is threadedly connected to the sliding seat 21. Both ends of the screw 24 are rotatably connected to the sliding groove. The rear end of the screw 24 extends to the rear side of the machine base 1 and is fixedly connected to the output shaft of the stepper motor 25.
[0044] Furthermore, such as Figure 1-4 As shown, in order to fix the tray 3 by the weight of the eggs in the egg carton, and to remove the tray when the egg carton is removed, thus releasing the fixation, a gravity self-locking component 4 is provided. This component includes two symmetrically arranged inserts 42 fixed to the bottom of the tray 3. The top of the I-shaped base plate 22 has slots 41 that mate with the inserts 42. The bottom of each insert 42 has two symmetrically arranged first inclined surfaces 44. The first inclined surfaces 44, away from the center of the I-shaped base plate 22, movably overlap the second inclined surface 45 on the top of the L-shaped pressing strip 43. The two L-shaped pressing strips 43 are symmetrically arranged and movably inserted into the slots 42. In the L-shaped groove opened in the inner wall of the slot 41, two symmetrically arranged third inclined surfaces 46 are opened on the end of the L-shaped pressing strip 43 away from the second inclined surface 45. A limiting plate 47 fixed to the bottom of the tray 3 is provided on one side of the insert strip 42. The limiting plate 47 is movably attached to the outside of the I-shaped base plate 22. A slot 48 is opened on the side wall of the limiting plate 47 that is movably attached to the outside of the I-shaped base plate 22. Two symmetrically arranged fourth inclined surfaces 49 are opened at the opening of the slot 48. The side wall of the L-shaped pressing strip 43 facing the slot 48 is fixed to the inner wall of the L-shaped groove by multiple springs 410. The springs 410 are made of carbon steel.
[0045] When the insert 42 moves downward in the slot 41 under the weight of the egg tray, the first inclined surface 44 will press against the second inclined surface 45, causing the L-shaped pressing strip 43 to press against the multiple springs 410, and causing one end of the two third inclined surfaces 46 on the L-shaped pressing strip 43 to move outward until it is inserted into the slot 48 opened on the limiting plate 47. Thus, with the weight of the egg tray and its multiple eggs, the tray 3 and the I-shaped base plate 22 are self-locked and fixed, which helps to ensure stability during the intermittent backward movement.
[0046] In practical use, when laser micro-engraving of multiple selenium-enriched eggs on an egg tray is required, the egg tray can be manually placed on the tray 3. Under the weight of the egg tray and the eggs, the tray 3 will cause the two inserts 42 and their two limiting plates 47 to move downwards. This causes the first inclined surface 44 at the bottom of the insert 42 to press against the second inclined surface 45 at the top of the L-shaped pressing strip 43, which in turn presses against the multiple springs 410. Furthermore, the two third inclined surfaces 46 on the L-shaped pressing strip 43 will move towards... The tray moves outward until it is inserted into the slot 48 on the limiting plate 47. With the help of the weight of the egg tray and its multiple eggs, the tray 3 and the I-shaped base plate 22 are self-locked, which helps to ensure stability during intermittent backward movement. In addition, after the multiple eggs on the marked egg tray are removed, the spring 410 will return to its original position under the action of the second inclined surface 45, which will push the insert 42 up and make the tray 3 easy to remove for cleaning without having to remove the screws to achieve the purpose of disassembly and fixation.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
