Description

Technical Field

[0001] This utility model belongs to the field of egg tray processing technology, and specifically relates to an egg tray processing and forming device. Background Technology

[0002] Egg trays are packaging tools used to hold eggs such as chicken eggs and duck eggs. Their main function is to absorb shock and facilitate transportation and carrying. Depending on the material they are made of, they can be divided into paper pulp egg trays, pearl cotton egg trays, and plastic egg trays.

[0003] Currently, plastic egg cartons are generally produced through extrusion molding. After molding, they are manually removed from the mold, a process that is extremely inefficient. In today's fast-paced production environment, time is money. Manual demolding requires workers to separate each egg carton from the mold, a process that is not only time-consuming and labor-intensive but also has limited operational speed. This inefficiency severely restricts the improvement of production capacity.

[0004] Currently, there is an urgent need to solve the problem of egg trays being difficult to demold quickly after extrusion molding. To address this, we have proposed an egg tray processing and molding device that enables rapid demolding. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an egg tray processing and forming device to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: an egg tray processing and forming device, including: an upper template and a lower template, an egg tray box is provided below the lower template, the lower template is set below the upper template, an air outlet is installed in the middle of the rear side below the upper template, and an air inlet is opened in the middle of the rear side above the lower template and the middle of the front side below the lower template respectively.

[0007] The lower template has multiple sets of ventilation holes through its upper and lower surfaces, and both air inlets are connected to the multiple sets of ventilation holes.

[0008] An air pump is installed on the lower left side of the egg tray, and the air pump is connected to the air outlet through an air inflator hose.

[0009] In a preferred embodiment, the egg tray has a flip-up opening at the top, and the lower template is located inside the flip-up opening.

[0010] In a preferred embodiment, a rotating rod is installed on each of the left and right sides of the lower template, a servo motor is installed on the right side of the egg tray, the output shaft of the servo motor is connected to the right rotating rod, and the left end of the left rotating rod extends out of the egg tray.

[0011] In a preferred embodiment, a support base is installed below the egg tray, and a stacking cavity is opened inside the lower part of the egg tray.

[0012] In a preferred embodiment, a hydraulic cylinder is installed above the upper template, and the piston rod of the hydraulic cylinder is connected to the upper template.

[0013] In a preferred embodiment, a top plate is installed above the hydraulic cylinder, and a vertical plate is installed behind the top plate, with the vertical plate fixed to the egg tray.

[0014] In a preferred embodiment, multiple sets of egg tray grooves are respectively formed on the upper and lower surfaces of the lower template.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. By setting up a servo motor, rotating rod, and flipping port, after the material is extruded and formed into an egg tray by the upper and lower templates, the lower template can be rotated to change the surface, so as to quickly complete the transition from primary forming to secondary preparation and improve production efficiency.

[0017] 2. By setting up an air pump, air outlet, air inlet, and multiple sets of ventilation holes, after the lower mold is flipped and the extruded egg tray is attached to the bottom of the lower mold, it is subjected to molding processing again.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: an egg tray processing and forming device, including: an upper template 1 and a lower template 5, an egg tray box 6 is provided below the lower template 5, the lower template 5 is set below the upper template 1, an air outlet 16 is installed in the middle of the rear side below the upper template 1, and an air inlet 17 is opened in the middle of the rear side above the lower template 5 and the middle of the front side below the lower template 5 respectively.

[0026] Multiple sets of ventilation holes 12 are opened through the upper and lower surfaces of the lower template 5, and both air inlets 17 are connected to the multiple sets of ventilation holes 12.

[0027] An air pump 13 is installed on the lower left side of the egg tray 6. The air pump 13 is connected to the air outlet 16 through an air inflator hose.

[0028] The egg tray 6 has a flip-up opening 7 at the top, and the lower template 5 is located inside the flip-up opening 7.

[0029] A rotating rod 14 is installed on each of the left and right sides of the lower template 5. A servo motor 10 is installed on the right side of the egg tray 6. The output shaft of the servo motor 10 is connected to the rotating rod 14 on the right side. The left end of the rotating rod 14 on the left side extends out of the egg tray 6.

[0030] A support base 8 is installed below the egg tray 6, and a stacking cavity 9 is opened inside the lower part of the egg tray 6.

[0031] A hydraulic cylinder 4 is installed above the upper template 1, and the piston rod of the hydraulic cylinder 4 is connected to the upper template 1.

[0032] A top plate 2 is installed above the hydraulic cylinder 4, and a vertical plate 3 is installed behind the top plate 2. The vertical plate 3 is fixed to the egg tray 6.

[0033] Multiple sets of egg tray slots 11 are respectively opened on the upper and lower surfaces of the lower template 5.

[0034] Please see Figures 1 to 3As the first embodiment of this utility model: In actual use, the material required for egg tray forming is placed on the lower template 5, and the hydraulic cylinder 4 drives the upper template 1 to descend into the egg tray groove 11 through the piston rod to close the mold with the lower template 5, thereby extruding and forming the material. After extrusion and forming, the upper template 1 is returned to its position, and the servo motor 10 drives the rotating rod 14 to rotate. The rotating rod 14 rotates the lower template 5 in the flipping opening 7, so that the formed egg tray rotates downward, realizing the change of the lower template 5. Then, the egg tray extrusion and forming operation can be carried out again in combination with the above steps, thereby quickly completing the transition from primary forming to secondary preparation, thereby improving production efficiency.

[0035] Please see Figures 1 to 4 As a second embodiment of this utility model: In conjunction with the further explanation of the first embodiment, during the mold closing process of the upper mold plate 1 and the lower mold plate 5 in the extrusion molding operation, the upper mold plate 1 descends, driving the air outlet 16 into the air inlet 17. At the same time, the air pump 13 is started. The air pump 13 transmits air to the air outlet 16 through the air inlet hose. The air can reach multiple sets of vent holes 12 through the air inlet 17. Since the upper end of the vent hole 12 is closed during the mold closing process of the upper mold plate 1 and the lower mold plate 5, the gas is output through the lower part of the vent hole 12. At the same time, it blows the egg tray attached to the lower mold plate 5 after molding. Under the action of the gas impact, it loosens and falls off, thereby realizing the rapid demolding of the egg tray. After the egg tray loosens and falls off, it falls into the stacking cavity 9. The subsequent egg tray is processed and molded in the same way as the above steps and then demolded, so that the egg tray can be stacked in the stacking cavity 9 after falling off, so as to facilitate centralized removal.

[0036] 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.
