Description

Technical Field

[0001] This utility model relates to the field of film application machines, and in particular to a film application machine for embedded freezer panels. Background Technology

[0002] In the manufacturing process of embedded freezers, their exterior panels (door panels) are mostly made of high-gloss steel plates or glass. In order to protect the surface from scratches during transportation and use, protective films need to be precisely applied to both sides. At present, the automated film application equipment commonly used in the industry can efficiently complete single-sided film application.

[0003] However, when existing laminating machines require double-sided lamination, they mainly rely on operators manually picking up, flipping, and repositioning the panel after single-sided lamination to apply the film to the other side. This manual flipping interrupts the automated production process, restricts the improvement of overall efficiency, and increases labor costs. Manual operation carries an uncontrollable risk of scratches. Operators' gloves, tools, or improper operation can easily leave fine scratches on the expensive, smooth panel surface, leading to product scrap. Furthermore, manual flipping makes it difficult to guarantee the accuracy of secondary positioning, which can easily cause secondary quality problems such as lamination skew and increased air bubbles, seriously affecting the consistency of product yield and production cycle.

[0004] Therefore, a film applicator for embedded freezer panels was designed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a film applicator for embedded freezer panels. It solves the problems of low efficiency, high cost, and easy damage to the panel or air bubbles caused by improper operation when applying film to both sides of the embedded freezer panel.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An embedded freezer panel laminating machine includes a worktable, a support frame, a film-winding roller, and a mounting frame disposed on the top of the worktable, two conveyor belts mounted on the mounting frame, and two flip discs located between the two conveyor belts for clamping and flipping the panel.

[0007] Preferably, a film-applying roller is provided on the top of the support frame.

[0008] Preferably, the flipping disk is disc-shaped, and its surface has multiple slots.

[0009] Preferably, a protective pad is fixedly disposed inside the card slot, and the protective pad is made of rubber.

[0010] Preferably, the two rotating discs are symmetrically arranged on both sides of the mounting frame, and a rotating shaft is fixedly connected to the center of each rotating disc.

[0011] Preferably, a cylinder is fixedly provided at one end of the rotating shaft, and a drive rod for driving it to rotate at a fixed angle is sleeved inside the cylinder.

[0012] Preferably, a limiting groove is formed on the inner wall of the cylinder, and multiple protrusions are fixedly provided on the side wall of the drive rod.

[0013] Preferably, the limiting groove is toothed, and the protruding rod moves along the path of the limiting groove.

[0014] Preferably, an electric cylinder for driving the drive rod to move back and forth is fixedly installed at the end of the drive rod away from the cylinder, and a fixed frame is rotatably installed on the outer wall of the cylinder, the fixed frame supporting the electric cylinder.

[0015] Preferably, the two conveyor belts have the same conveying direction, and the mounting frame is fixedly provided with two symmetrical connecting frames on one side of the discharge end.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a drive rod, a protruding rod, and a cylinder with a limiting groove to achieve intermittent flipping of the rotating disc. The linear motion of the cylinder is converted into the angular rotation of the disc, causing it to rotate at a fixed angle, thus achieving precise flipping of the panel during transport. The rotating disc design replaces the original manual flipping process, enabling double-sided film application and significantly improving production cycle time and overall efficiency. The rubber protective pads on the rotating disc ensure flexible contact with the high-gloss panel surface during clamping and flipping, effectively reducing the risk of scratches and scrap due to improper manual operation or tool contact, thus ensuring product yield.

[0024] Please see Figure 1-4 An embedded freezer panel laminating machine includes a worktable 1, a support frame 11, a film winding roller 2 and a mounting frame 3 disposed on the top of the worktable 1, two conveyor belts 31 mounted on the mounting frame 3, and two flip discs 4 located between the two conveyor belts 31 for clamping and flipping the panel. The top of the support frame 11 is provided with a film-applying roller 5, and the flipping disk 4 is in the shape of a disc with multiple slots on its surface. A protective pad 41 is fixedly installed in the slot. The protective pad 41 is made of rubber. Two flipping disks 4 are symmetrically arranged on both sides of the mounting frame 3, and a rotating shaft 42 is fixedly connected to the center of the flipping disk 4. A cylinder 43 is fixedly installed at one end of the rotating shaft 42. A drive rod 44 for driving it to rotate at a fixed angle is sleeved inside the cylinder 43. A limiting groove 431 is opened on the inner wall of the cylinder 43. Multiple protrusions 441 are fixedly installed on the side wall of the drive rod 44. The limiting groove 431 is toothed, and the protrusions 441 move along the path of the limiting groove 431. An electric cylinder 45 for driving it to move back and forth is fixedly installed at the end of the drive rod 44 away from the cylinder 43. A fixed frame 46 is rotatably installed on the outer wall of the cylinder 43. The fixed frame 46 supports the electric cylinder 45. The two conveyor belts 31 have the same transmission direction. Two symmetrical connecting frames 32 are fixedly installed on one side of the mounting frame 3 at the discharge end.

[0025] After the equipment is started, the panel to be coated is carried and transported to the designated workstation by two conveyor belts 31 that move in the same direction. Subsequently, two rotating discs 4 located on both sides of the conveyor belts 31 move towards each other under the drive of electric cylinders 45, flexibly holding the panel through the slots on their disc surfaces and the rubber protective pads 41. Specifically, the electric cylinders 45 drive the drive rods 44 to move back and forth, and the protruding rods 441 on them move along the path of the toothed limiting grooves 431 on the inner wall of the cylinder 43, thereby driving the cylinder 43, the rotating shaft 42 and the rotating discs 4 to rotate at a preset fixed angle. This allows for precise rotation of the panel in mid-air, resulting in accurate rotation of the panel angle. This fixed-angle rotation ensures that the panel can be smoothly picked up from one side of the conveyor belt 31 and accurately placed onto the other side or the adjusted conveyor belt 31 for the next process. After rotation, the panel is placed back onto the conveyor belt 31, and the film-applying roller 5 completes the film-applying operation on the other side. Finally, it is output through the connecting frame 32 area, thus realizing automatic cyclic film application.
