Abstract
Description
Technical Field
[0001] This utility model relates to a carbon fiber turnover box, which is mainly used in finished oil packaging projects and in the production line of paperless packaging of oil products. Background Technology
[0002] During the production of finished oil products, the processed oils need to be packaged for subsequent transportation and use.
[0003] Currently, PP material turnover boxes are used. After bagging, filling, and sealing, they enter the box changing equipment along the conveyor belt. After the turnover box reaches the working position, the bottom plate opens, the material bag is removed to the bottom carton, and the bottom plate of the turnover box closes with the support of the flip plate of the box changing equipment, thus completing the box changing work.
[0004] Currently used turnover boxes accumulate debris after multiple uses, and damage to material bags and contamination of greases can occur during box replacement, affecting grease quality and posing food safety risks. Furthermore, the weight of these turnover boxes disrupts the smooth operation of the production line, and repeated collisions pose a risk of damage to the boxes and packaging equipment. Summary of the Invention
[0005] The purpose of this utility model is to solve existing technical problems and provide a lightweight, high-strength carbon fiber turnover box that will not shed debris or damage the material bag.
[0006] To achieve the above objectives, the technical solution adopted is:
[0007] This utility model discloses a carbon fiber turnover box, comprising a rectangular box body with an open top. The bottom plate of the box body is composed of two identical hinged plates. Each hinged plate is rotatably connected to the bottom of the two long side plates of the box body. U-shaped grooves are respectively opened in the upper part of the two short side plates of the box body. A flap that matches the shape of the U-shaped groove is provided in each U-shaped groove. The bottom of the flap is connected to the short side plate by a hinge. The flap can be opened outward by 90° and can be rotated inward back into the U-shaped groove. A hanging plate is fixed horizontally on the outer wall of each long side plate. The hanging plate is used to support the box body. A limiting block is fixed horizontally on the short side plate below each U-shaped groove.
[0008] This invention allows the sealed grease to smoothly exit the container, greatly reducing the possibility of grease contamination and preventing damage to the bag during its descent. Attached Figure Description

[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0014] As shown in the attached figure, a carbon fiber turnover box includes a rectangular box body with an open top. The bottom plate 6 of the box body is composed of two identical hinged plates. Each hinged plate is rotatably connected to the bottom of the two long side plates 1 of the box body. The rotatable connection structure can be as follows: multiple hinged plate rotating rings are provided at the bottom connection of each hinged plate and the long side plate, and multiple box body rotating rings are provided at the bottom of the long side plate. Each hinged plate rotating ring is inserted between two box body rotating rings and is connected by a stainless steel shaft 7 passing through the hinged plate rotating ring and the box body rotating ring. The hinged plate can rotate 90 degrees around the stainless steel shaft to rotate from a horizontal position to a vertical position. Preferably, the ends of the short sides of the two hinged plates are inclined inwards towards the box body to ensure that the material bag can be smoothly released into the bottom carton.
[0015] U-shaped grooves are respectively opened on the upper part of the two short side plates of the box body. A flap 3 that matches the shape of the U-shaped groove is provided in each U-shaped groove. The bottom of the flap is connected to the short side plate by a hinge 4. The flap can be opened outward by 90° and can be rotated inward back into the U-shaped groove.
[0016] A hanging plate 2 is fixed horizontally on the outer wall of each of the long side panels for supporting the box. A limiting block 5 is fixed horizontally on the short side panel below each U-shaped groove, so that the turnover box maintains a certain distance from the previous turnover box during operation on the production line.
[0017] Preferably, protective strips 8 are affixed to the bottom of the long side plate at the position of the rotating ring of the box to ensure that the shaft will not damage the bag during the falling process.
[0018] The method of using this device is as follows: a polygonal frame is formed by the side plate and cooperates with the closed bottom plate to hold the packaging bag. The turnover box is erected by the hanging plate 2, so that the bottom plate 6 on the lower side can be flipped open to remove the packaging bag from the turnover box.
[0019] This carbon fiber turnover box runs on an oil packaging production line, sequentially going through the processes of bagging, filling, sealing, and box changing. The PE packaging bag is placed inside the turnover box by a bagging machine, fitting snugly against the inner wall. After bagging, the turnover box is conveyed to the filling and sealing machine. In the sealing machine, the PE packaging bag is heat-sealed. The flap 3 opens 90° outwards to straighten the packaging bag and complete the heat sealing. The flap 3 then rotates back to its original position, placing the heat-sealed bag inside the turnover box. It then enters the box changing machine via a conveyor belt. At the box changing station, the turnover box is hung on the machine by a hanging plate. At this time, the bottom plate 6 opens, and the sealed PE packaging bag naturally falls into the bottom paper packaging box. The protective strip 8 ensures that the bottom plate's rotating shaft does not scratch the packaging bag during its descent. Once the packaging bag is completely inside the bottom paper packaging box, the bottom plate 6 closes due to the action of the box changing machine's cylinder, and the bag re-enters the bagging machine for the next workflow.
