Description

Technical Field

[0001] This invention belongs to the field of fragile item packaging technology, specifically relating to an auxiliary boxing device for egg products. Background Technology

[0002] As living standards continue to improve, more and more functional egg products are entering consumers' lives, such as sterile eggs, low-cholesterol eggs, and selenium-enriched eggs. Reports indicate that compared to innovation at the traditional product level, these products also have greater potential for iteration at the transaction and distribution levels. With the continuous changes in transaction channels and demand, more and more egg products are being purchased in large quantities through online channels.

[0003] Unlike offline sales, online sales place greater emphasis on quality control throughout the distribution process. The fragile nature of egg products, in particular, imposes stricter requirements on logistics. Therefore, shockproof egg trays have been specially designed for packaging egg products. For example... Figure 1 As shown, a shockproof egg tray sold on an e-commerce platform is made of pearl cotton and has multiple through-holes in the egg tray. Each egg tray has four elastic protrusions to secure the product. Because pearl cotton is elastic, it provides better shock absorption and cushioning compared to traditional hard-shell egg trays, meeting logistics requirements.

[0004] While shockproof egg trays can reduce damage rates, they also have significant drawbacks compared to rigid egg trays. For example, because the egg slots in rigid egg trays are larger than the eggs themselves, a vacuum egg packer can be used to directly transfer eggs in batches into each slot. Shockproof egg trays, however, rely on protrusions in the egg slots to press and hold the eggs in place. Therefore, the fit between the slots and the eggs is tight, and the limited slot size makes it impossible to ensure that every egg is properly packed. Consequently, eggs must be manually picked up and placed in one by one, significantly reducing packaging efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an auxiliary boxing device for egg products, which can expand the egg tray space to achieve the purpose of batch loading egg products using a vacuum egg packer.

[0006] The present invention is implemented as follows: an auxiliary boxing device for egg products, comprising:

[0007] A workbench, the workbench having a tabletop;

[0008] An expansion mechanism includes multiple extrusion members movably disposed on the table surface, wherein half of the extrusion members move along the longitudinal direction and the other half of the extrusion members move along the latitudinal direction; each extrusion member has several pressure plates and the extrusion members are paired in pairs and moved in opposite directions to each other, thereby forming several extrusion units with four pressure plates.

[0009] Connecting rods, four of which are provided and are respectively located at the ends of the extruders that move in the same direction;

[0010] A traction mechanism having a traction end for receiving traction and a connecting end for connecting corresponding connecting rods;

[0011] After being pulled, the pulling end can drive the extrusion parts in four directions to move synchronously through the connecting end, so that the pressure plate in each extrusion unit can extrude the protrusion of the corresponding egg groove to expand the accommodating space.

[0012] Both the longitudinal and latitudinal directions are parallel to the surface of the worktable.

[0013] Furthermore, it also includes a separation grate, which is movably installed on the platform in a vertical direction and has a plurality of grate bars for supporting shock-absorbing egg trays.

[0014] Furthermore, handles are provided on the two opposite sides of the separation grate.

[0015] Furthermore, the extrusion member has a pull rod, and the pressure plate is integrally and vertically connected to the pull rod at equal intervals.

[0016] Furthermore, it also includes a reset spring, one end of which is connected to a support on the platform, and the other end is connected to a corresponding connecting rod.

[0017] Furthermore, the traction mechanism includes a first traction rope, a second traction rope, and a traction sleeve; the first traction rope is provided in multiple groups, one end of each group of first traction ropes is connected to a corresponding connecting rod, and the other end is fixedly connected to one end of the second traction rope, and the other end of the second traction rope is fixedly connected to the traction sleeve.

[0018] Furthermore, the four sides of the workbench are provided with through holes corresponding to the passage of each first traction rope.

[0019] Furthermore, it also includes a limiting member for restricting the movement distance of the extruder, the limiting member being disposed on the table surface.

[0020] The beneficial effects of this invention are:

[0021] (1) The present invention uses several extrusion parts that move in different directions. Under the traction of the traction mechanism, they move synchronously, driving the pressure plate to extrude the protrusions in each egg slot, thereby expanding the accommodating space and realizing the purpose of using a vacuum egg packer to put egg products into the egg slot in batches, which greatly improves packaging efficiency.

[0022] (2) The traction mechanism in this invention uses a traction rope as a power transmission component, which is not only simple in structure and easy to install, but also simple and quick to operate, achieving the purpose of pedal operation.

[0023] (3) The separation grate in this invention can quickly separate the shockproof egg tray from the pressure plate by lifting it upwards. The operation is simple and reliable. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0037] like Figures 2 to 10 As shown, an auxiliary boxing device for egg products includes: a workbench 1, an expansion mechanism 2, a connecting rod 3, and a traction mechanism 4.

[0038] The workbench 1 has a tabletop 10, which is square and can be fitted with legs 11 at the bottom, so that it can be used with a work chair or stool to enable the operator to sit and work.

[0039] The expansion mechanism 2 includes multiple pressing members 5 movably mounted on the tabletop 10. For a 5×5 shockproof egg tray 23, which has 25 egg slots 24, the number of pressing members 5 is 20, with half of the pressing members 5 moving along the warp direction and the other half moving along the weft direction. For example... Figure 6 As shown, the extrusion piece 5 is made of 2mm thick metal after being cut and processed into sheet metal. The extrusion piece 5 has a pull rod 6 and five pressure plates 7 integrally and vertically connected to the pull rod 6 at equal intervals. The width of the pressure plates 7 is greater than the width of the protrusion 25, ensuring coverage of the protrusion 25 and reducing the difficulty of initial positioning. The extrusion pieces 5 are paired in pairs and moved in opposite directions, forming 25 extrusion units with four pressure plates 7 each. That is, adjacent pressure plates 7 are arranged in opposite directions and move in opposite directions. Thus, when two extrusion pieces 5 are pulled, they move in opposite directions, thereby extruding two opposite protrusions 25 in the same egg groove 24. Following this principle, the four pressure plates 7 in each extrusion unit simultaneously extrude the corresponding protrusions 25, thereby expanding the accommodating space.

[0040] For the movable installation of the expansion mechanism 2, several fixing members 8 with slots 9 are provided on the platform 10. The pull rod 6 of the extrusion member 5 is slidably disposed in the slot 9, and the slot 9 achieves constraint in three directions. The pull rod 6 of the extrusion member 5 moving in the longitudinal direction is located above the pull rod 6 of the extrusion member 5 moving in the latitudinal direction, thus avoiding motion interference. Therefore, the upper extrusion member 5 limits the lower extrusion member 5, and the upper extrusion member 5 is further limited by the upper shockproof egg tray 23, thus allowing it to move only in a straight line.

[0041] There are four connecting rods 3, which are respectively located at the ends of the extrusion parts 5 that move in the same direction. That is to say, each connecting rod 3 can drive multiple extrusion parts 5 to move synchronously under traction.

[0042] The traction mechanism 4 has a pulling end for receiving pull and a connecting end for connecting the corresponding connecting rods 3. In a preferred embodiment, the traction mechanism 4 includes a first traction rope 12, a second traction rope 13, and a traction sleeve 14. Multiple first traction ropes 12 are arranged in groups. One end of each group of first traction ropes 12 is connected to a corresponding connecting rod 3, and the other end is fixedly connected to one end of a second traction rope 13. The other end of the second traction rope 13 is fixedly connected to the traction sleeve 14. Clearly, the first traction rope 12 serves as the connecting end, and the traction sleeve 14 serves as the pulling end. When the traction sleeve 14 is pulled, the traction force is transmitted to each first traction rope 12, thereby acting evenly on the connecting rods 3 and achieving synchronous traction of the extrusion member 5.

[0043] The advantage of using a traction rope is that it has a simple structure, requires no additional parts, and is a low-cost and easy-to-implement synchronous pulling method.

[0044] After being pulled, the pulling end can drive the extrusion pieces 5 in four directions to move synchronously through the connecting end, so that the pressure plate 7 in each extrusion unit can press the protrusion 25 of the corresponding egg groove 24 to expand the accommodating space.

[0045] Both the longitudinal and latitudinal directions are parallel to the table surface 10 of the workbench 1.

[0046] As a preferred example, to facilitate the separation of the shock-absorbing egg tray 23 from the expansion mechanism 2 after the egg products 27 have been placed, this example also includes a separation grate 15. The separation grate 15 is a square structure, with its four corners mounted on four guide posts 26 on the table via linear bearings, thereby enabling vertical movement. The separation grate 15 has several grate bars 16 that support the shock-absorbing egg tray 23. The separation grate 15 is placed above the expansion mechanism 2, serving both to support the shock-absorbing egg tray 23 and to separate the shock-absorbing egg tray 23 from the expansion mechanism 2. The grate bars 16 are provided to prevent interference with the pressure plate 7.

[0047] As a preferred example, handles 17 are provided on two opposite sides of the separation grate 15. The handles 17 make it easier to lift the separation grate 15 and the shockproof egg tray 23 it supports.

[0048] As a preferred example, in order to achieve the reset of the expansion mechanism 2, this example also includes a reset spring 18. One end of the reset spring 18 is connected to the support 19 on the platform 10, and the other end is connected to the corresponding connecting rod 3. The ends of both the support 19 and the connecting rod 3 are provided with pins 20 for connecting the reset spring 18, thereby achieving hook connection.

[0049] As a preferred example, the four sides of the workbench 1 are provided with through holes 21 corresponding to the passage of each first traction rope 12.

[0050] As a preferred example, this example also includes a limiting member 22 for restricting the movement distance of the extruder 5, which is disposed on the table surface 10. The limiting member 22 is divided into a front limiting member 22 and a rear limiting member 22. When the connecting rod 3 moves the extruder 5, it stops after contacting the front limiting member 22. At this time, the distance W3 between the inner sides of the two opposing pressure plates 7 is greater than the diameter D of the egg product 27, so that the egg product 27 can be smoothly placed in. When the connecting rod 3 is reset by the reset spring 18, it stops after contacting the rear limiting member 22. At this time, the distance D1 between the outer sides of the two opposing pressure plates 7 is less than the distance W2 between the two opposing protrusions 25, so that it can be inserted into the egg slot 24. The limiting member 22 can be installed at the corresponding position on the table surface 10 using bolts or pins.

[0051] like Figure 10 As shown, during use, the shockproof egg tray 23 is placed on the separating grate 15, ensuring that each egg slot 24 corresponds to a pressing unit and that the two are aligned as coaxially as possible. The pressing plate 7 of each pressing unit corresponds to a protrusion 25 on the side wall of the egg slot 24. Then, the traction sleeve 14 is stepped on, causing the pressing element 5 in the expansion unit to move away from the center. At this time, the pressing plate 7 begins to press the corresponding protrusion 25, making the distance between the two opposing pressing plates 7 in the egg slot 24 greater than the diameter of the egg product 27. At this point, the vacuum egg packer adsorbs 25 egg products 27 and transfers them into the egg slot 24. Then, the traction sleeve 14 is released, and the separating grate 15 is moved upwards in advance. At this time, the shockproof egg tray 23 gradually separates from the expansion mechanism 2. After separation, the protrusion 25 in the egg slot 24 returns to its original shape and firmly fixes the egg product 27, thus completing the packaging.

[0052] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
