Description

Technical Field

[0001] This utility model relates to the field of furniture renovation film processing technology, and in particular to a furniture renovation film cutting and positioning frame. Background Technology

[0002] Furniture refurbishing film is a thin film material that can be pasted onto the surface of old furniture to cover up imperfections, change its appearance, and provide protection, thereby achieving furniture refurbishment.

[0003] Under current conditions, a positioning mechanism for cutting automotive film, as disclosed in CN222003649U, is commonly used. This mechanism includes a shearing device for cutting automotive film, with an internal extrusion assembly and a limiting component for positioning the film. The limiting component positions the film to prevent movement or curling during the shearing process. However, this positioning mechanism relies solely on the extrusion rod and movable plate to laterally press the film. In its natural state, the film is prone to slack areas, which can easily deform or shift, resulting in serrated burrs on the cut edges. While this mechanism positions the film by pressing the edges, it struggles to properly fix the central or specially shaped areas. When cutting large areas, unfixed areas are easily pulled by the cutting tool, causing wrinkles and affecting the cutting quality. Furthermore, the cutting head is directly exposed, posing a safety hazard of accidental hand contact for operators. Utility Model Content

[0004] The purpose of this invention is to solve the problem that furniture renovation film is prone to wrinkles during the cutting process in the prior art, and to propose a furniture renovation film cutting and positioning frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A furniture renovation film cutting and positioning frame includes a positioning bracket for positioning the furniture renovation film body. Slide rods are fixedly installed on both sides of the positioning bracket, and pressure applying frame one and pressure applying frame three are slidably sleeved on the slide rods. A positioning plate one for initially positioning the furniture renovation film body is provided between the two pressure applying frames one. A tensioning mechanism for tensioning the furniture renovation film body is provided on the positioning bracket. An electric guide rail is fixedly installed between the two pressure applying frames three, and a cutting blade for cutting the furniture renovation film body is fixedly installed on the sliding block of the electric guide rail. A protective cover for protection is provided between the two pressure applying frames three.

[0006] Preferably, an electric telescopic rod is fixedly installed inside the pressure frame, and an installation block is fixedly installed at the output end of the electric telescopic rod, with the positioning plate located between the two installation blocks.

[0007] Preferably, the tensioning mechanism includes two lead screws rotatably mounted on the positioning bracket, and matching nuts are slidably sleeved on the lead screws. A second pressure frame is fixedly mounted on the nut, and a second positioning plate for repositioning the furniture renovation film body is provided between the two second pressure frames. A support plate for supporting the furniture renovation film body is fixedly mounted between the two nuts.

[0008] Preferably, an electric telescopic rod 2 is fixedly installed inside the pressure frame 2, and an installation block 2 is fixedly installed at the output end of the electric telescopic rod 2, and the positioning plate 2 is located between the two installation blocks 2.

[0009] Preferably, an electric telescopic rod three is fixedly installed inside the pressure frame three, and an installation block three extending outside the pressure frame three is fixedly installed at the output end of the electric telescopic rod three, and the protective cover is located between the two installation blocks three.

[0010] Preferably, a limiting frame for limiting the cutting of the furniture renovation film body is fixedly installed between the two mounting blocks three, and the limiting frame is provided with an elongated guide hole corresponding to the cutting head.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model places the furniture renovation film body below the positioning plate one and positioning plate two. The electric telescopic rod one and electric telescopic rod two drive the positioning plate one and positioning plate two to position the furniture renovation film body. After positioning, the synchronous motor drives the lead screw to rotate, which tightens the furniture renovation film body after positioning. This effectively prevents problems such as reduced cutting accuracy caused by loosening of the furniture renovation film body, and ensures the cutting quality of the renovation film.

[0012] 2. This utility model uses an electric telescopic rod to move the mounting block three downwards. The mounting block three then moves the limiting frame to limit the furniture renovation film body, preventing wrinkles from forming on the furniture renovation film body due to the pressure of the cutting head at the moment of cutting. This ensures that the edges of each cut are neat. The mounting block three also moves the protective cover downwards simultaneously, forming a physical isolation zone before cutting begins. This isolates the high-speed cutting head from the operator's hands, helping to improve the safety of the equipment. Attached Figure Description

[0027] The functional principle of this utility model can be explained through the following operation methods: The controller controls the opening of electric telescopic rod 14 and electric telescopic rod 210, adjusts them to a suitable telescopic length, and then places the furniture renovation film body under the positioning plate 16 and positioning plate 212 respectively. The electric telescopic rod 14 drives the mounting block 15 to move down, and the mounting block 15 drives the positioning plate 16 to perform initial positioning of the furniture renovation film body. At the same time, the electric telescopic rod 210 drives the mounting block 211 to move down, and the mounting block 211 drives the positioning plate 212 to position the furniture renovation film body again. After positioning is completed, the controller controls the synchronous motor to start, the synchronous motor drives the lead screw 7 to rotate, and the lead screw 7 drives the pressure frame 9 to move through the nut 8, thus tensioning the furniture renovation film body after positioning. After tensioning is completed, the controller controls the electric telescopic rod 15 to open, the electric telescopic rod 15 drives the mounting block 16 to move down, the mounting block 16 drives the limit frame 18 to limit the furniture renovation film body, and at the same time drives the protective cover 17 to move down to form a physical isolation zone. Subsequently, the controller controls the electric guide rail 19 to start, and the sliding block drives the cutting head 20 to perform cutting operations.
