Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for egg carton packaging, specifically to a pusher table for egg carton packaging. Background Technology

[0002] Egg cartons, also known as egg trays, are a type of egg packaging used to protect eggs from breakage due to vibration and collisions during handling and transportation. For environmental reasons, many egg cartons on the market are made of paper. To save on transportation costs, paper egg cartons are mainly bundled together and then secured with shrink film. To reduce the number of shrink wrapping operations, they are typically bundled in groups of 100, with two bundles combined for each shrink wrapping. When using a heat shrink wrapping machine, because the length of the shrink film is a preset fixed value, two bundles of egg cartons must be aligned side-by-side when entering the machine's conveyor belt; otherwise, the packaging will fail. Manual alignment is inefficient and cannot guarantee accurate alignment. If a cylinder-controlled pusher plate is used for linear reciprocating movement, the operator must wait for the cylinder to fully reset the pusher plate before placing two new bundles of egg cartons on the worktable, resulting in a long waiting time that cannot match the efficiency of a heat shrink wrapping machine. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a pusher for egg carton packaging; this pusher eliminates waiting time and its pushing efficiency can match that of a heat shrink film packaging machine.

[0004] The technical solution adopted by this utility model is: a pusher table for egg carton packaging, comprising a frame and a pusher rack mounted on the frame; wherein...

[0005] The frame is equipped with a storage platform, the upper part of which is a storage area for placing materials, and the lower part of which is a movable cavity for the pusher frame to move.

[0006] The pusher is located on the side of the platform and is connected to a circulation drive mechanism located in the movable cavity. The circulation drive mechanism drives the pusher to push the material on the platform to the next work station and then controls the pusher to return to its original position through the movable cavity.

[0007] Preferably, the pusher includes several horizontally arranged push plates, a connecting plate connected to the back of the push plates, and a base plate connected to the connecting plate, wherein the push plates are perpendicular to the material movement direction.

[0008] Preferably, the platform includes several support plates arranged in parallel, with a longitudinal gap between two adjacent support plates to allow the connecting plate to move, and the longitudinal gap is parallel to the material movement direction.

[0009] Preferably, the storage platform is provided with a transverse gap at the original position of the pusher frame for the pusher plate to rise and return to its original position, and the transverse gap is perpendicular to the longitudinal gap.

[0010] Preferably, the cyclic drive mechanism includes a lifting drive source disposed at the bottom of the pusher frame, and the lifting drive source is connected to a lateral movement drive source disposed in the movable cavity.

[0011] Preferably, the lifting drive source includes a movable frame, a push rod connected to the base plate, and a lifting cylinder disposed within the movable frame and controlling the lifting of the push rod.

[0012] Preferably, the push rod is supported on both sides by guide rods connected to the base plate, and the top of the movable frame is provided with a guide sleeve for the guide rods to pass through.

[0013] Preferably, the lateral movement drive source includes a guide rail parallel to the material movement direction, a slider connected to the bottom of the lifting drive source, and a motor that drives the slider to reciprocate along the guide rail.

[0014] Preferably, the storage platform is provided with a positioning plate on the side where the material moves.

[0015] Preferably, the frame is provided with a protective cover above the original position of the pusher.

[0016] Preferably, the slider and the guide rail are connected by a lead screw.

[0017] Preferably, a control switch for controlling the operation of the cyclic drive mechanism is provided on the side of the protective cover.

[0018] This utility model has the following advantages compared with the prior art:

[0019] This utility model's pusher platform utilizes a circulating drive mechanism to push the material on the shelf to the next workstation. Then, the pusher descends to the bottom of the shelf and returns to its original position via the movable cavity. Since the pusher's return stroke does not occur on the shelf surface, workers can place materials on the shelf during the pusher's return stroke without waiting, significantly improving the pushing efficiency and ensuring it matches the packaging efficiency of the heat shrink film packaging machine.

Detailed Implementation

[0029] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0030] Reference Figure 1-7 A pusher platform for egg carton packaging includes a frame 1 and a pusher rack 2 mounted on the frame 1. The frame 1 has a storage platform 3, with a material storage area 4 above the platform 3 and a movable cavity 5 below the platform 3 for the pusher rack 2 to move. The pusher rack 2 is located to the side of the platform 3, meaning its initial position is at the beginning of the material conveying direction. The pusher rack 2 is connected to a circulating drive mechanism 6 located within the movable cavity 5. The circulating drive mechanism 6 drives the pusher rack 2 to push the material on the platform 3 to the next station, and then controls the pusher rack 2 to return to its original position via the movable cavity 5. In this embodiment, the pusher platform is located at the feed end of a heat shrink film packaging machine 7. Since the return trip of the pusher rack 2 is not on the table of the storage platform 3, the staff can place the materials on the storage platform 3 during the return trip of the pusher rack 2 without waiting, which greatly improves the pushing efficiency of the pusher table and ensures that the pushing efficiency can match the packaging efficiency of the heat shrink film packaging machine 7.

[0031] Specifically, refer to Figure 3 The pusher rack 2 includes several horizontally arranged push plates 21, connecting plates 22 connected to the back of the push plates 21, and a base plate 23 connected to the connecting plates 22. The push plates 21 are perpendicular to the material movement direction. In this embodiment, two horizontally arranged push plates 21 are provided, and the two ends of the base plate 23 are respectively connected to the two connecting plates 22. The total length of the two ends of the two push plates 21 is greater than the total length of the two bundles of egg cartons, thereby ensuring that the two bundles of egg cartons can be fed side by side into the conveyor belt of the heat shrink film packaging machine 7.

[0032] To ensure that the pusher plate 21 can move on the platform 3 during the outward movement of the pusher rack 2, the platform 3 includes several parallel support plates 31. A longitudinal gap 32 is formed between adjacent support plates 31 to allow the connecting plate 22 to move. The longitudinal gap 32 is parallel to the material movement direction. The design of the longitudinal gap 32 also ensures that the connecting plate 22 moves along the material movement direction without deviation. The number of longitudinal gaps 32 is the same as the number of connecting plates 22. In this embodiment, three support plates 31 are provided, forming two longitudinal gaps 32, each allowing one connecting plate 22 to move. During the outward movement of the pusher rack 2 pushing the material, refer to... Figure 4 The push plate 21 is movable on the support plate 31; the connecting plate 22 passes through the longitudinal gap 32, with its upper part on the support plate 31 and its lower part below the support plate 31; the bottom plate 23 is movable at the bottom of the middle support plate 31.

[0033] Since the entire pusher rack 2 returns to its original position via the movable cavity 5, to ensure that the push plate 21 of the pusher rack 2 can return to the platform 3, the platform 3 is provided with a transverse gap 33 at the original position of the pusher rack 2 for the push plate 21 to rise back to its original position. The transverse gap 33 is perpendicular to the longitudinal gap 32. A descending gap 34 is also maintained between the platform 3 and the conveyor belt of the packaging machine 7 for the push plate 21 to descend. The push plate 21 of the pusher rack 2 first descends to the movable cavity 5 via the descending gap 34, and then rises to the original position of the platform 3 via the transverse gap 33.

[0034] In order to achieve the cyclic movement of the pusher 2, refer to Figure 6The circulating drive mechanism 6 includes a lifting drive source 61 located at the bottom of the pusher frame 2, which is connected to a lateral movement drive source 62 located within the movable cavity 5. Specifically, the lifting drive source 61 includes a movable frame 611, a push rod 612 connected to the base plate 23, and a lifting cylinder 613 located within the movable frame 611 and controlling the lifting of the push rod 612. The lifting cylinder 613 drives the base plate 23 to rise and fall via the push rod 612, thereby driving the entire pusher frame 2 to rise and fall. Guide rods 614 connected to the base plate 23 are provided on both sides of the push rod 612, and a guide sleeve 615 is provided at the top of the movable frame 611 for the guide rods 614 to pass through. The design of the guide rods 614 and guide sleeves 615 ensures that the pusher frame 2 rises and falls smoothly without deviation. The lateral movement drive source 62 includes a guide rail 621 parallel to the material movement direction, a slider 622 connected to the bottom of the lifting drive source 61, and a motor 623 that drives the slider 622 to reciprocate along the guide rail 621. The slider 622 and the guide rail 621 are connected by a lead screw.

[0035] To ensure that the two bundles of materials enter the conveyor belt of the packaging machine 7 at the same position each time, the placement platform 3 is equipped with a positioning plate 8 on the side where the material moves. The other side of the placement platform 3 opposite to the positioning plate 8 is the feeding end. The operator can push the material from the feeding end onto the positioning plate 8, and then push it onto the conveyor belt by the push plate 21.

[0036] Furthermore, a protective cover 9 is provided above the original position of the pusher frame 2 on the frame 1, which can provide protection and improve the safety performance of the pusher platform. A control switch 10 for controlling the operation of the cycle drive mechanism 6 is provided on the side of the protective cover 9.

[0037] Working principle: Refer to Figure 7 The staff first places the turnover cart 11 filled with materials on one side of the feeding end of the pusher platform. Then, the two stacked bundles of egg carton materials 12 are pushed onto the positioning plate 8 in sequence. Then, the control switch 10 is activated. The motor 623 of the lateral movement drive source 62 drives the slider 622 to slide along the guide rail 621 in the material conveying direction, which drives the push plate 21 of the pusher frame 2 to push the two bundles of materials onto the conveyor belt of the packaging machine 7. Then, the lifting cylinder 613 of the lifting drive source 61 drives the bottom plate 23 to descend through the push rod 612, thereby driving the entire pusher frame 2 to descend from the descending gap 34 between the platform 3 and the conveyor belt of the packaging machine 7 into the movable cavity 5. Next, the motor 623 of the lateral movement drive source 62 drives the slider 622 to move the pusher frame 2 to below the lateral gap 33. The lifting cylinder 613 of the lifting drive source 61 drives the bottom plate 23 to rise through the push rod 612, thereby driving the entire pusher frame 2 to rise and reset. Staff can place materials on the storage platform 3 during the return trip of the pusher 2 without waiting.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
