Description

Technical Field

[0001] The present invention relates to a food machine, in particular to a conveying device for food after film coating. Background Art

[0002] Food wrapping is an effective way to ensure food hygiene and safety. The food wrapping process usually involves wrapping the food in a continuous string with a strip of food packaging film. The food is arranged at intervals in the food strip formed by wrapping with the food packaging film. After that, the wrapped food strips need to be transported to the next station to be sealed and cut one by one. Since the food strips will lose the conveying traction after sealing and cutting, and the food in the string is only separated by the food packaging film, the conveying process is poorly stable, and it is difficult to ensure continuous and stable operation of the production process. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a floating clamping and conveying device for coated food, which can realize the traction and conveying of the coated food belt and maintain a stable traction and conveying effect regardless of whether there is food in the coated food belt.

[0004] In order to solve the above technical problems, the present invention provides a floating clamping conveying device for coated food, including a frame and a conveyor belt transmission pair supported on the frame, a floating supporting member is provided between the upper edge of the conveyor belt and the lower edge of the conveyor belt in the conveyor belt transmission pair, the floating supporting member is swingably supported on the frame, a clamping belt conveying pair is provided above the conveyor belt transmission pair, the driving wheel of the clamping belt conveying pair is rotatably supported on the frame, the driven wheel of the clamping belt conveying pair is swingably supported on the frame through a swing arm, the swinging end of the swing arm and the swinging end of the floating supporting member are respectively connected to the two ends of the clamping floating lever, and the clamping floating lever is swingably supported on the frame.

[0005] After adopting the above technical solution, the clamping belt conveyor pair arranged above the conveyor belt conveyor pair will cooperate with the conveyor belt conveyor pair to clamp and convey the wrapped food belt. The floating supporting member provided between the upper edge of the conveyor belt and the lower edge of the conveyor belt in the conveyor belt conveyor pair will make the upper edge of the conveyor belt on the conveyor belt conveyor pair push upward toward the conveying edge of the conveyor belt in the clamping belt conveyor pair relative to the conveying edge of the conveyor belt in the clamping belt conveyor pair, so that the upper edge of the conveyor belt in the conveyor belt conveyor pair and the relative conveying edge of the conveyor belt in the clamping belt conveyor pair can be close to or fit together, forming a traction and conveying effect on the wrapped food belt located therein. The floating supporting part is swing-supported on the frame, and one end of the clamping belt conveyor pair is also swing-supported on the frame through a swing arm. The swinging end of the swing arm and the swinging end of the floating supporting part are respectively connected to the two ends of the clamping floating lever swing-supported on the frame. When the swinging end of the swing arm in the clamping belt conveyor pair is pressed toward one end of the clamping floating lever due to its own weight, the other end of the clamping floating lever will make the swinging end of the floating supporting part swing upward, so that the upper edge of the conveyor belt on the conveyor belt conveyor pair is pushed upward toward the conveying edge of the conveyor belt in the opposite clamping belt conveyor pair, forming a clamping and conveying of the coated food belt. When the part of the food belt with food passes through, the floating supporting part will be pressed down by the food, and the swinging end of the clamping belt conveyor pair will be lifted up accordingly through the clamping floating lever. When only the film passes through the food belt, the floating supporting part will, under the action of the deadweight of the swinging end of the swing arm in the clamping belt conveyor pair, clamp the floating lever to make the upper edge of the conveyor belt upward and stick to the relative conveying edge in the clamping belt conveyor pair, so that very thin film can be clamped to achieve clamping and traction conveying, so that no matter whether there is food in the food belt after wrapping, a stable traction and conveying effect can be maintained, thereby ensuring the stable operation of the food wrapping equipment.

[0006] In a preferred embodiment of the present invention, the swinging end of the swing arm and the swinging end of the floating support member are respectively connected to the ends of the clamping floating lever. With this embodiment, when the clamping floating lever swings, both ends maintain contact and connection by sliding slightly between the swinging end of the swing arm and the swinging end of the floating support member, eliminating the need for other connecting rod-like components to maintain the connection, resulting in a simple structure.

[0007] In another preferred embodiment of the present invention, the driving wheel of the clamping belt conveyor pair is rotatably supported on the frame via the clamping belt drive shaft. With this embodiment, the driving wheel of the clamping belt conveyor pair is fixedly connected to the clamping belt drive shaft, which can conveniently achieve stable operation of the clamping belt conveyor pair.

[0008] In another preferred embodiment of the present invention, the swing axis of the swing arm is located on the axis of the clamping belt drive shaft. With this embodiment, the tension of the conveyor belt in the clamping belt conveyor pair can be guaranteed not to be affected by the swing.

[0009] In a further preferred embodiment of the present invention, a swing arm gravity balancing spring is provided between the clamping floating lever and the frame. This embodiment reduces the force exerted by the swing arm on the clamping floating lever in the clamping belt conveyor pair, ensuring that the food is not deformed during the clamping and conveying process.

[0010] In another preferred embodiment of the present invention, the swing arm's gravity-balancing spring is a tension spring. One end of the tension spring is connected to the floating clamping lever, with the connection point located on the floating clamping lever near the swinging end of the floating support. The other end of the tension spring is connected to the frame below the floating clamping lever via an adjustment screw. This embodiment effectively balances the weight of the swing arm, and the spring tension can be adjusted using the adjustment screw to accommodate the gripping and conveying requirements of foods of varying hardness.
