Description

Technical Field

[0001] This utility model relates to the field of packaging machinery, specifically to a packaging mold used in food packaging. Background Technology

[0002] Packaging machines are devices used to package products into final sales units, with continuous transmission devices playing a crucial role. In food processing enterprises, the conveying of food raw materials, semi-finished products, and finished products in food machinery production lines relies on manual handling or food conveyors. Traditional manual handling methods are labor-intensive for operators, have low conveying efficiency, and are prone to food contamination, posing hygiene risks. Existing food conveying devices generally consist of a single conveyor belt and conveyor hub. These conveyor belts have a large area, making it difficult to clean food residues accumulated during production, which can lead to mold and spoilage over time, affecting food quality. Therefore, a food conveying device that is easy to clean is needed.

[0003] CN110228690B discloses a food conveying device: The food conveying device comprises, from top to bottom, a conveyor belt, a washing device, and a turning device. The conveyor belt is composed of several independent conveyor strips. Cylindrical connecting posts are fixed at both ends of each conveyor strip. Each connecting post has six annular baffles. Adjacent connecting posts are connected by chain plates, and the connecting posts and their chain plates are rotatably connected. A turning gear is fixed at the end of each connecting post, and a square-faced locking post is fixed in front of the turning gear. The conveyor strips, connecting posts, turning gears, and locking posts are integrated and move simultaneously. Two transmission gears mesh with the chain below, and these transmission gears are located inside the entire conveyor belt.

[0004] The conveyor belt is fully extended so that its top and bottom are on a horizontal plane. A fixed frame on the outer side of the chain is fixed to the base. A gap exists in the middle of the fixed frame, through which a cuboid column on the reversing gear passes, ensuring the stability of the conveyor strip and preventing rotation. A portion of a rack is located on the inner side of the lower left end of the annular fixed frame, where the reversing gear meshes with the rack. Below the conveyor belt is a base with a support frame fixed on it. A pipe is fixed to the support frame, with a water inlet at the bottom front of the pipe extending into the conveyor belt. Several nozzles are located below the end of the pipe, with the length of each nozzle equal to the length of the conveyor strip. These nozzles are positioned above the rack, and a drying decoration is located on the right side above the rack and fixed to the pipe. This technical solution allows for automatic cleaning during use, eliminating the need for manual cleaning, saving manpower, and improving cleaning efficiency. It also prevents food residue from falling during transport from becoming moldy and spoiling, affecting food quality, and keeps the conveyor device clean at all times.

[0005] While the aforementioned transmission device solves the problem of moldy and spoiled residue falling during the conveying process, affecting food quality and making cleaning difficult, it does not offer effective solutions to the problem of loose transmission belts in existing transmission mechanisms. Loose transmission belts can lead to unstable equipment movement, vibration or shaking, increased equipment wear, shortened equipment lifespan, and reduced product processing accuracy. Furthermore, it does not address the need for machine downtime for adjustments.

[0006] The applicant disclosed a continuous transmission device for food packaging in CN2025204609332. This continuous transmission device uses a cylinder to drive a module, which in turn drives a paddle plate to reciprocate, thus transmitting power to the packaged goods and overcoming the shortcomings of existing chain drives. Simultaneously, this utility model has multiple wide grooves in the middle of the transmission panel to facilitate the movement of the paddle, allowing for easy rinsing out of food residue during production and maintaining cleanliness of the device. During product packaging, the upper and lower molds work together to achieve product packaging. The lower mold is responsible for fixing the packaged product box below the upper mold, facilitating packaging. However, during production, it has been found that food residue often spills onto the lower mold during packaging. Since existing lower molds are often integrated, spillage during packaging often necessitates stopping the packaging process and disassembling the entire lower mold for cleaning, significantly impacting packaging efficiency. Utility Model Content

[0007] This utility model provides a brief overview of the chosen inventive concepts, which are further described in the detailed description section below. This utility model summary is not intended to identify key or essential features of the claimed subject matter, nor to help define the scope of the claimed subject matter.

[0008] The purpose of this invention is to overcome the problem in existing technologies where food residue spilled on the lower packaging mold during the production process is not cleaned in time, leading to mold growth and spoilage, thus affecting food quality. This invention provides a packaging mold for food packaging. The packaging mold provided by this invention overcomes the problem in existing technologies where cleaning food residue from the packaging mold requires pausing the production process, disassembling the mold for cleaning, and affecting the continuity of the packaging process and production efficiency.

[0009] To achieve the above objectives, this utility model provides a layered design packaging lower mold for packaging, which includes a layered lower mold upper assembly (1), a layered lower mold lower assembly (2), and a lower mold support assembly (3). The layered lower mold upper assembly (1) is installed above the layered lower mold lower assembly (2), and the layered lower mold lower assembly (2) is installed on the lower mold support assembly (3). The lower mold support assembly (3) includes a tray connecting rod (3.1), a locking cylinder (3.2), a cam fixing block (3.3), a motor mounting plate (3.4), and a servo mounting plate (3.5). The tray connecting rod (3.1) is connected to the locking cylinder (3.2), the cam fixing block (3.3) is connected to the layered lower mold lower assembly (2) and the lower mold support assembly (3) respectively, and the motor mounting plate (3.4) is fixedly connected to the servo mounting plate (3.5).

[0010] This utility model also provides a packaging machine for packaging food, which includes a frame, a film feeding shaft, a film receiving shaft, a packaging mold, an instrument box, an alarm light, a transmission device, and the layered lower mold described in this utility model.

[0011] Beneficial effects of this utility model

[0012] This utility model features a layered lower mold design, and the layered lower mold is made lightweight for easy pulling. After cleaning, the layered lower mold needs to return to its original position. It is positioned during the pushing process using guides and anti-collision blocks are set to limit the final position. Finally, a locking device is used to fix the double-layered lower mold to prevent loosening during operation. Due to the layered structure, the inflation and de-inflation positions need to be sealed twice to prevent air leakage. A short-stroke lifting structure is adopted and a locking device is used to lock it in place. Attached Figure Description
