Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, and in particular to a food liner paper machine. Background Technology

[0002] The function of a food liner machine is to separate two adjacent food items by placing the liner underneath them, thus effectively preventing food from sticking together.

[0003] Chinese Patent CN216785150U discloses a food liner machine. This machine includes an unwinding system and a conveying system. The unwinding system includes a feed roll, a power mechanism, and a cutting mechanism. The power mechanism includes a drive roller, a driven roller, and a pressure regulating component. The liner tape passes between the drive roller and the driven roller and moves to the cutting mechanism. The pressure regulating component adjusts the pressure applied by the drive roller to the driven roller. The cutting mechanism cuts the liner tape to form liner paper. The conveying system includes a first conveying mechanism and a second conveying mechanism. The first conveying mechanism conveys the liner paper. The first conveyor belt of the second conveying mechanism intersects with the second conveyor belt of the first conveying mechanism. The second conveying mechanism conveys food to the first conveying mechanism, and the food and liner paper come into contact at the intersection. Because the pressure between the drive roller and the driven roller can be adjusted by the pressure regulating component, the liner tape will not slip or be damaged when passing between the drive roller and the driven roller.

[0004] However, the device still has shortcomings: when the actual paper roll end passes through the gap between the cutting mechanism and the two adjacent conveying mechanisms, it will be very troublesome due to the narrow space, and the entire device uses the method of cutting the release paper before conveying it to carry food, which makes the structure complicated.

[0023] Example 1

[0024] like Figures 1-4As shown, the present invention proposes a food liner paper machine, including a frame 1, a cutting mechanism, a tray 15, and an air suction assembly. Two vertical plates 2 are arranged in parallel on the frame 1, and a breathable conveyor belt A3 and a conveyor belt B4 are spaced apart between the two vertical plates 2. A cutting station is set between the conveyor belts A3 and B4, and a drive mechanism is set on the vertical plates 2 to drive the conveyor belts A3 and B4 to run synchronously. The drive mechanism includes a drive roller A, a driven roller A, a drive roller B, a driven roller B, a transmission assembly 5, and a stepper motor 6. The transmission assembly 5 includes a pulley A, a pulley B, and a synchronous belt. The drive roller A and the driven roller A are a group and are both rotatably connected to the vertical plate 2. The drive roller A and the driven roller A are connected by a conveyor belt A3. The drive roller B and the driven roller B are a group and are both rotatably connected to the vertical plate 2. The drive roller B and the driven roller B are connected by a conveyor belt B4. The roller shafts of pulley A and the driven roller A are coaxially connected. The roller shafts of pulley B and the drive roller B are coaxially connected. The pulley A and the pulley B are connected by a synchronous belt. The body of the stepper motor 6 is connected to the vertical plate 2. The output end of the stepper motor 6 is connected to the roller shaft of the drive roller A through a coupling. A guide groove 101 is provided on the frame 1 near one end of the conveyor belt A3. A slide rod 20 is provided in the guide groove 101. Two brackets 21 are spaced apart in the guide groove 101. Both brackets 21 are slidably connected to the slide rod 20. A bidirectional module 22 is provided on the frame 1 to drive the two brackets 21 to move closer or further away synchronously. The cutting mechanism is provided on the frame 1. The cutting mechanism includes a knife holder 7, a cutter 9, and a cylinder 10. The knife holder 7 is connected to the frame 1 and is located between the conveyor belt A3 and the conveyor belt B4. A bracket 8 is provided on the frame 1. A guide rod that slides along its height direction is provided on the bracket 8. The cutter 9 is located directly above the knife holder 7 and is connected to the bottom of the guide rod. The body of the cylinder 10 is connected to the bracket 8, and the output end of the cylinder 10 is connected to the cutter 9. In the working state, the cutting mechanism cuts the release paper along the cutting station between the conveyor belt A3 and the conveyor belt B4. There are two pallets 15, both connected to the vertical plate 2. Each pallet 15 has several support rollers 16 spaced apart to support the load-bearing surfaces of conveyor belts A3 and B4 respectively. Each pallet 15 has a cavity and several upward-facing ventilation holes 151 communicating with the cavity. An air intake assembly is mounted on the frame 1. The assembly includes an air collection hood 18 and a fan 19. The air collection hood 18 is connected to the frame 1. A duct 17 communicating with the cavity is mounted on the pallet 15. The end of the duct 17 furthest from the pallet 15 is connected to the input end of the air collection hood 18. The fan 19 is mounted on the air collection hood 18, and its input end is connected to the exhaust end of the air collection hood 18. When in operation, the suction component draws air from the cavity of the pallet 15 so that the release paper adheres to the load-bearing surfaces of the conveyor belts A3 and B4 and moves with the conveyor belts.

[0025] In this embodiment, the central axis of the release paper roll is placed in the slot of the corresponding side bracket 21. The bidirectional module 22 is started, and the bidirectional module 22 drives the brackets 21 on both sides to move closer and slide and limit the release paper roll. The end of the release paper roll is pulled and placed on the load surface of the conveyor belt A3. The fan 19 is started, and the fan 19 draws air from the cavity of the tray 15 so that the release paper adheres tightly to the conveyor belt A3. The stepper motor 6 continues to drive the conveyor belt A3 and the conveyor belt B4 to run, and the release paper moves with it. When the release paper moves to the conveyor belt B4, the stepper motor 6 is paused, and the cylinder 10 is started to press down the cutter 9. The cutter 9, together with the cutter holder 7, cuts the release paper between two adjacent doughs. Then the stepper motor 6 resumes operation. This intermittent action cuts the release paper and ensures that the bottom of each dough is covered with release paper.

[0026] Example 2

[0027] like Figure 3 As shown, the food liner paper machine proposed in this utility model, compared with the first embodiment, has a photoelectric sensor 11 with a detection probe facing the load surface of the conveyor belt B4 on the support 8. The photoelectric sensor 11 is, but is not limited to, a reflective photoelectric sensor. A controller 12 connected to the photoelectric sensor 11 is set on the frame 1. The controller 12 is a PLC controller. The controller 12 controls the connected cylinder 10 and stepper motor 6.

[0028] In this embodiment, when the release paper moves to below the lens of the photoelectric sensor 11, the photoelectric sensor 11 determines the position of the food and feeds the signal back to the controller. The controller then controls the stepper motor 6 to stop running and simultaneously controls the cylinder 10 to start and press down the cutter 9. After the cutting action is completed, the cutter 9 is reset and the stepper motor 6 is started again.

[0029] Example 3

[0030] like Figure 1 and Figure 2 As shown, the food liner paper machine proposed in this utility model, compared with Embodiment 1 or Embodiment 2, has a U-shaped frame 13 slidably connected along its height on the upright plate 2, and a pressure roller 14 rotatably connected to the U-shaped frame 13, with the pressure roller 14 resting on the conveyor belt A3.

[0031] In this embodiment, the pressure roller 14 applies pressure to the release paper using its own weight, which can further improve the stability of the release paper during the paper feeding process, and make it easy to make the release paper adhere to the load-bearing surface of the conveyor belt A when pulling the release paper, and make it easy to adjust the position of the release paper on the conveyor belt A before starting the fan 19.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
