Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and in particular to a packaging device for producing egg tart crusts. Background Technology

[0002] Food processing equipment, also known as food machinery, is a general term for all mechanical equipment used to process food raw materials into finished or semi-finished products. Food includes processed food, semi-finished products, and unprocessed food. Food processing equipment can be categorized as follows: General equipment: quick-freezing equipment, cleaning equipment, drying equipment, sterilization equipment, filling equipment, water treatment equipment, sorting equipment, extraction equipment, heat exchange equipment, and conveying equipment; Specialized equipment: snack food equipment, vegetable processing equipment, fruit processing equipment, meat product processing equipment, baking equipment, aquatic product processing equipment, fruit and vegetable processing equipment, dairy product equipment, condiment processing equipment, and beverage processing equipment; Testing equipment: measuring instruments and metering equipment; Packaging equipment: packaging machines, sealing machines, packing equipment, labeling equipment, filling equipment, and wrapping equipment.

[0003] Egg tart crust is a type of food, and its origin can be traced back to medieval England, where people made similar foods with milk, sugar, eggs, and spices. In the 1920s, Guangzhou restaurants localized the Western fruit tart by using lard instead of butter to reduce costs and adding egg liquid to create flaky egg tarts. After the egg tart crusts are made, they are packaged and stored for sale.

[0004] Currently, when packaging finished egg tart shells, due to the large number of shells to be placed, manual labor is used to place them multiple times. However, this repeated manual placement of egg tart shells into the plastic packaging bags causes the edges of the shells to deform due to repeated compression, significantly increasing production costs. Furthermore, the existing packaging for egg tart shells lacks sufficient airtightness, allowing the shells inside to become damp. To prevent damage from moisture, the shelf life is shortened to 3-5 days, which further increases inventory costs. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a packaging device for egg tart shell production, so as to fundamentally solve the problems that existing manual repeated placement of egg tart shells will cause them to be damaged and that insufficient sealing will cause the egg tart shells to become damp.

[0006] According to an embodiment of the present invention, a packaging device for producing egg tart shells includes a housing, a storage assembly embedded in the bottom of the housing, a fixing assembly disposed on the top of the storage assembly, and a sealing assembly disposed on the top of the fixing assembly; The fixing assembly includes a base plate, at least two small lifting rods disposed at one end of the base plate away from the storage assembly, a top plate disposed on the top of the two small lifting rods, and at least two adsorption components embedded in the top of the base plate and the bottom of the top plate; The sealing assembly includes an air extraction component, at least two small telescopic rods disposed on the bottom plate away from the air extraction component, a bottom lifting component disposed on the two small telescopic rods away from the bottom plate, at least two limiting rods disposed on the bottom lifting component away from the air extraction component, a top lifting component movably passing through the top of the two limiting rods, and at least two slide rails disposed on both sides of the top plate. The bottom lifting component and the top lifting component have the same structure and are arranged vertically oppositely. Specifically, the bottom lifting assembly is moved towards the storage assembly by the two small telescopic rods. While the bottom lifting assembly is moving, the top lifting assembly is moved along the two slide rails by the two limiting rods. After moving a certain distance, the bottom lifting assembly and the top lifting assembly will fit together.

[0007] Furthermore, the vacuum assembly includes a vacuum pump disposed at the top of the top plate away from the storage assembly, a vacuum pipe embedded in the vacuum pump facing the storage assembly, at least two long rods disposed on the top lifting assembly facing the vacuum pipe, and an elastic U-shaped plate movably penetrating the top of the top plate facing the storage assembly. The vacuum pipe passes through the middle of the elastic U-shaped plate, and the elastic U-shaped plate drives the vacuum pipe to move horizontally. Furthermore, the top lifting assembly includes two irregularly shaped frames, a clamping plate embedded in the bottom of the top plate facing the bottom of the storage assembly, at least two elastic push rods one disposed on the clamping plate away from the bottom lifting assembly, a heating plate movably disposed on the clamping plate away from the storage assembly, and at least two elastic push rods two disposed on the heating plate away from the bottom lifting assembly.

[0008] Furthermore, the top lifting assembly is slidably connected to the two slide rails via the corresponding two irregularly shaped frames, and the bottom lifting assembly is fixedly connected to the extended ends of the two small telescopic rods via the corresponding two irregularly shaped frames. The two small telescopic rods drive the two limiting rods and the two irregularly shaped frames of the top lifting assembly to move horizontally together via the two irregularly shaped frames of the bottom lifting assembly.

[0009] Furthermore, each of the irregularly shaped frames is inclined at one end toward the storage assembly, and the end that fits into the first elastic push rod is the longest end. When the irregularly shaped frame moves toward the storage assembly, it will first push the first elastic push rod to move vertically, and then push the second elastic push rod to move vertically.

[0010] Furthermore, the elastic U-shaped plate, each elastic push rod one and each elastic push rod two are provided with springs and are fixedly connected to the corresponding positions of the top plate or the bottom plate, so as to facilitate their return to their original positions after movement.

[0011] Furthermore, the clamping plate has a groove in the middle of one end away from the two elastic push rods. When the clamping plate of the bottom lifting assembly and the clamping plate of the top lifting assembly are attached together, the grooves of the two clamping plates will form a hole, and the hole will fit into the opening at the bottom of the suction pipe.

[0012] Furthermore, each of the adsorption components includes multiple suction cup openings and an interface disposed at the middle of one end of the base plate or the top plate away from the placement assembly.

[0013] Furthermore, the storage assembly includes a support plate movably disposed at the bottom of the base plate, a large lifting rod disposed in the middle of the support plate, a telescopic plate disposed on the base plate near one end of the large lifting rod, a large telescopic rod disposed in the middle of the bottom of the base plate, and a shelf disposed on the large telescopic rod away from the base plate. The end of the telescopic plate away from the base plate is movably connected to the extended end of the large lifting rod. The large lifting rod drives the fixing assembly and the sealing assembly to tilt accordingly through the telescopic plate.

[0014] Furthermore, the housing includes a top outer shell nested on the top plate at the end away from the bottom plate, and a bottom outer shell nested on the bottom plate at the end away from the top plate. The inner wall of the bottom outer shell is fixedly connected to the bottom of the support plate, and a through hole is provided on the bottom outer shell at the end away from the support plate so that the fixing assembly and the sealing assembly can be tilted up and down.

[0015] Compared with the prior art: In the above embodiments of the present invention, the packaging equipment for producing egg tart shells first places a plastic packaging bag with a certain degree of toughness on top of the base plate. Then, the adsorption components inside the base plate and top plate are connected to an external air pump. After connection, the external air pump uses the adsorption components to adsorb the top and bottom of the plastic packaging bag. Then, two small lifting rods move the top plate and the top of the adsorbed plastic packaging bag upward, causing the plastic packaging bag to be opened. Then, the egg tart shells are placed on the storage assembly. The storage assembly tilts the fixing assembly so that the egg tart shells can be poured into the plastic packaging bag at once. After pouring, the fixing assembly is laid flat. Two small telescopic rods move the bottom lifting assembly towards the storage assembly. As the bottom lifting assembly moves, two limit rods move the top lifting assembly along two slide rails, causing the bottom and top lifting assemblies to fit together. The vacuum assembly moves with the bottom lifting assembly to the plastic packaging bag. When the bottom and top lifting assemblies fit together, the vacuum assembly removes the air from the plastic packaging bag, creating a vacuum. The bottom and top lifting assemblies then heat-seal the plastic packaging bag, extending the shelf life of the packaged egg tart shells. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please see Figures 1 to 7 The diagram shows a packaging device for producing egg tart shells according to an embodiment of the present invention. It includes a housing, a storage assembly 1 embedded at the bottom of the housing, a fixing assembly 2 disposed at the top of the storage assembly 1, and a sealing assembly 3 disposed at the top of the fixing assembly 2. The fixing assembly 2 includes a base plate 21, at least two small lifting rods 22 disposed at one end of the base plate 21 away from the storage assembly 1, a top plate 23 disposed at the top of the two small lifting rods 22, and at least two adsorption components 24 embedded at the top of the base plate 21 and the bottom of the top plate 23. The sealing assembly 3 includes an air extraction component 31, at least two small telescopic rods 32 disposed at one end of the base plate 21 away from the air extraction component 31, and at least two sealing components 24 disposed at the top of the two small telescopic rods 32. The bottom lifting assembly is located at one end of the base plate 21, at least two limiting rods 33 are located at the end of the bottom lifting assembly away from the exhaust assembly 31, a top lifting assembly is movably inserted through the top of the two limiting rods 33, and at least two slide rails 34 are located on both sides of the top plate 23. The bottom lifting assembly and the top lifting assembly have the same structure and are arranged vertically oppositely. The bottom lifting assembly is moved towards the storage assembly 1 by two small telescopic rods 32. While the bottom lifting assembly is moving, the top lifting assembly is moved along the two slide rails 34 by the two limiting rods 33. After moving a certain distance, the bottom lifting assembly and the top lifting assembly will fit together.

[0023] Furthermore, the vacuum pump assembly 31 includes a vacuum pump 311 disposed at the top of the top plate 23 away from the storage assembly 1, a vacuum pipe 312 embedded in the vacuum pump 311 facing the storage assembly 1, at least two long rods 313 disposed at the top lifting assembly facing the vacuum pipe 312, and an elastic U-shaped plate 314 movably penetrating the top of the top plate 23 facing the storage assembly 1. The vacuum pipe 312 passes through the middle of the elastic U-shaped plate 314, and the elastic U-shaped plate 314 drives the vacuum pipe 312 to move horizontally. The top lifting assembly includes two irregularly shaped frames 35, a clamping plate 36 embedded at the bottom of the top plate 23 facing the storage assembly 1, at least two elastic push rods 37 disposed at the end of the clamping plate 36 away from the bottom lifting assembly, and a movably disposed at the end of the clamping plate 36 away from the bottom lifting assembly. The heating plate 38 is located at one end of the storage assembly 1, and at least two elastic push rods 39 are located at the end of the heating plate 38 away from the bottom lifting assembly. The top lifting assembly is slidably connected to two slide rails 34 via two corresponding irregular frames 35, and the bottom lifting assembly is fixedly connected to the extended ends of two small telescopic rods 32 via two corresponding irregular frames 35. The two small telescopic rods 32 drive the two limiting rods 33 and the two irregular frames 35 of the top lifting assembly to move horizontally together via the two irregular frames 35 of the bottom lifting assembly. Each irregular frame 35 is inclined at the end facing the storage assembly 1, and the end that fits against the elastic push rod 37 is the longest end. When the irregular frame 35 moves towards the storage assembly 1, it first pushes the elastic push rod 37 to move vertically, and then pushes... The second elastic push rod 39 moves vertically. The elastic U-shaped plate 314, each elastic push rod 37, and each elastic push rod 39 are equipped with springs and are fixedly connected to the corresponding positions of the top plate 23 or bottom plate 21, facilitating their return to their original positions after movement. The clamping plate 36 has a groove in the middle of the end away from the two elastic push rods 37. When the clamping plate 36 of the bottom lifting assembly and the clamping plate 36 of the top lifting assembly are in contact, the grooves of the two clamping plates 36 form a hole, which fits into the opening at the bottom of the suction pipe 312. Each suction assembly 24 includes multiple suction cup openings and an interface located in the middle of the end of the bottom plate 21 or top plate 23 away from the storage assembly 1. The storage assembly 1 includes a support plate 11 movably mounted on the bottom of the bottom plate 21, and a spring mounted on the support plate 11. The system includes a large lifting rod 12 in the middle, a telescopic plate 15 located at one end of the base plate 21 near the large lifting rod 12, a large telescopic rod 13 located at the bottom center of the base plate 21, and a shelf 14 located at the large telescopic rod 13 away from the base plate 21. The end of the telescopic plate 15 away from the base plate 21 is movably connected to the extended end of the large lifting rod 12. The large lifting rod 12 drives the fixing assembly 2 and the sealing assembly 3 to tilt accordingly through the telescopic plate 15. The housing includes a top outer shell 4 nested in the top plate 23 away from the bottom plate 21, and a bottom outer shell 5 nested in the bottom plate 21 away from the top. The inner wall of the bottom outer shell 5 is fixedly connected to the bottom of the support plate 11, and a through hole is opened at the end of the bottom outer shell 5 away from the support plate 11 so that the fixing assembly 2 and the sealing assembly 3 can tilt up and down.

[0024] In practice, a plastic bag with a certain degree of flexibility is first placed on top of the base plate 21. Then, the top plate 23 is moved downwards using two small lifting rods 22, so that the bottom of the top plate 23 is in contact with the top of the plastic bag. After contact, an external air pump is connected to the adsorption assembly 24 inside the base plate 21 and the top plate 23. Once the interface between the external air pump and the adsorption assembly 24 is connected, it is turned on. The external air pump will adsorb the corresponding positions of the plastic bag through the multiple suction cups of the adsorption assembly 24. After the top and bottom of the plastic bag are adsorbed, the top plate 23 is moved upwards using the two small lifting rods 22. At the same time, the adsorption assembly 24 inside the top plate 23 will move the top of the plastic bag upwards as well, so that the plastic bag (as shown in the attached image) is adsorbed. Figure 2 The tart shells are spread out and then placed in two rows on the shelf 14. After placement, the large telescopic rod 13 will move the shelf 14 towards the plastic bag. When the shelf 14 is partially inside the plastic bag, the extended end of the large lifting rod 12 will pull out and lift the telescopic plate 15. Correspondingly, the base plate 21 connected to the telescopic plate 15 will also rotate along the top of the support plate 11, thus forming an inclined shape with the shelf 14 higher than the base plate 21, so that the shelf 14 can be tilted. 4. The top tart shells gradually slide into the plastic packaging bag on the top of the base plate 21. After they are all slid in, the extended end of the large lifting rod 12 will pull the telescopic plate 15 back to its original position so that the height of the base plate 21 and the shelf 14 is level. At the same time, the large telescopic rod 13 will also move the shelf 14 back to its original position. This operation can put multiple tart shells into the plastic packaging bag at once, avoiding the situation where the tart shells inside are deformed due to repeated squeezing caused by manual multiple insertions into the plastic packaging bag.

[0025] Next, the two small telescopic rods 32 will drive the irregular frame 35 of the bottom lifting assembly to move in the opposite direction to the limiting rod 33. During the movement, the irregular frame 35 of the bottom lifting assembly will drive the irregular frame 35 of the top lifting assembly to move accordingly along the slide rail 34 through the limiting rod 33. The irregular frame 35 of the top lifting assembly can slide up and down along the limiting rod 33, which facilitates the up and down movement of the irregular frame 35 of the top lifting assembly with the top plate 23. When the irregular frame 35 moves to the elastic push rod 37, it will continue to move horizontally. The elastic push rod 37 moves towards the plastic packaging bag under the push of the irregular frame 35. Simultaneously, as the elastic push rod 37 of the top lifting assembly moves towards the plastic packaging bag, it drives the two long rods 313 located at the top of the elastic push rod 37 to move downwards. When the two long rods 313 reach the top of the elastic U-shaped plate 314, they continue to move downwards, causing the elastic U-shaped plate 314 to move towards the vacuum pump 311 under the push of the two long rods 313. At the same time, the suction pipe 312 is carried by the elastic U-shaped plate 314... As the vacuum tube 312 moves together, the opening at the bottom of the suction tube 312 moves into the plastic packaging bag. The movement of the elastic push rod 37 causes the clamps 36 of the bottom lifting assembly and the top lifting assembly to gradually come together, clamping the opening at the bottom of the suction tube 312 into the grooves of the two clamps 36. The plastic packaging bag is also clamped between the two clamps 36. Then, the external air pump is turned off, causing the plastic packaging bag to be released by the two suction components 24. After release, the vacuum pump 311 will pump the contents of the plastic packaging bag through the suction tube 312. The air in the compartment is extracted, and when the irregular frame 35 moves to the elastic push rod 39, the elastic push rod 39 will move towards the plastic packaging bag under the push of the irregular frame 35. The heating plate 38 will move accordingly with the movement of the elastic push rod 39. When the two heating plates 38 clamp the corresponding position of the plastic packaging bag, the corresponding position of the plastic packaging bag is heat-sealed, so that the egg tart shell inside the plastic packaging bag is in a vacuum-sealed state, thereby extending the shelf life of the packaged egg tart shell and greatly reducing inventory costs.

[0026] Following the heat-sealing of the plastic packaging bag, the two small telescopic rods 32 retract, causing the irregularly shaped frames 35 of the bottom and top lifting components to move together toward the limiting rod 33. Meanwhile, the elastic push rods 37 and 39, without the pressure of the irregularly shaped frames 35, will spring back to their original positions with the corresponding springs. Similarly, the elastic U-shaped plate 314 will also spring back to its original position with the corresponding springs without the pressure of the long rod 313, thus enabling the sealing operation of the next plastic packaging bag and improving the practicality of the packaging equipment for egg tart production.

[0027] In summary, the packaging equipment for producing egg tart shells in the above embodiments of the present invention first places a plastic packaging bag with a certain degree of toughness on top of the base plate 21. Then, the adsorption component 24 inside the base plate 21 and the top plate 23 is connected to the external air pump. After connection, the external air pump adsorbs the top and bottom of the plastic packaging bag through the adsorption component 24. Then, the top plate 23 and the top of the adsorbed plastic packaging bag are moved upward through two small lifting rods 22, so that the plastic packaging bag is opened. Then, the egg tart shells are placed on the storage assembly 1. The storage assembly 1 will tilt the fixing assembly 2 so that the egg tart shells can be poured into the plastic packaging bag at once. After pouring, the fixing assembly 2 is laid flat. Then, the bottom lifting component is moved towards the storage assembly 1 by two small telescopic rods 32. While the bottom lifting component is moving, the top lifting component is moved along the two slide rails 34 by two limit rods 33, so that the bottom lifting component and the top lifting component are in contact. The vacuum component 31 moves to the plastic packaging bag with the bottom lifting component. When the bottom lifting component and the top lifting component are in contact, the vacuum component 31 will extract the air from the plastic packaging bag, making it a vacuum. The bottom lifting component and the top lifting component will heat-seal the plastic packaging bag, thereby extending the shelf life of the packaged egg tart shells.
