Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, and in particular to a film cutting component for a film applicator. Background Technology

[0002] During production, storage, transportation, and installation, the surface smoothness of tiles is easily damaged by friction, collision, or stains, affecting product quality and commercial value. To prevent such damage, a protective film is commonly applied to the tile surface. Tile laminating machines are key equipment for automating the application of protective film, typically including unwinding, alignment, application, cutting, and rewinding stations. The performance of the film-cutting assembly directly determines the accuracy, efficiency, and smoothness of the cut, which is crucial for the lamination quality and overall machine efficiency. However, existing tile laminating machines mostly use cylinders as the power component for their cutting assembly. The cylinder's movement speed is greatly affected by air pressure fluctuations, load changes, and lubrication conditions, making it difficult to maintain a constant speed. Especially during start-up and shutdown, there is noticeable impact and "creeping" phenomenon, affecting processing efficiency; they also suffer from high energy consumption and high noise levels. Furthermore, the cylinder's response is delayed; there is a time lag between the control signal being sent, the solenoid valve switching, and the cylinder driving the load to begin movement, which cannot meet the demands of high-efficiency, high-precision laminating machines. Utility Model Content

[0003] The purpose of this invention is to provide a film cutting component for a laminating machine, which has a simple and reasonable structure, stable and reliable operation, can efficiently cut film strips without noise, is easy to use, and has high precision.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A film cutting assembly for a film applicator includes a mounting frame, a servo motor, a reducer, a fisheye connecting rod, a cutter fixing seat, a heated aluminum blade, a fisheye bearing connecting rod, and a vertical bearing;

[0006] The mounting frame is a vertically installed mounting bracket; the speed reducer is located at the top of the mounting frame, and a servo motor is connected to the top of the speed reducer.

[0007] The servo motor is connected to a horizontally positioned rotating shaft via a reducer, driving the rotating shaft to rotate.

[0008] Vertical bearings are fitted at both ends of the rotating shaft, and the bottom of the vertical bearings is fixed on the mounting frame.

[0009] The left and right ends of the rotating shaft are respectively connected to eccentric wheels, and the edge of the eccentric wheel is hinged to the top of the fisheye bearing connecting rod;

[0010] The cutter fixing seat is horizontally set, and its left and right ends are respectively hinged to the bottom ends of the fisheye bearing connecting rod;

[0011] The heated aluminum blade is horizontally positioned and fixed to the bottom of the cutter holder;

[0012] The heated aluminum knife includes a knife holder, a cutting blade, a heating rod (electric heating rod), and a thermocouple. A thermocouple is a temperature sensor that converts a temperature signal into a small voltage signal, allowing the temperature of the object being measured (the heated aluminum knife) to be determined by measuring this voltage value. The cutting blade is vertically mounted and fixed to the bottom of the knife holder. A horizontally positioned cavity is located in the middle of the knife holder, extending through the left and right end faces of the knife holder. The heating rod is horizontally positioned and passes through this cavity. A temperature sensor mounting cavity is located above the cavity, and the thermocouple is housed within this cavity.

[0013] The mounting frame is equipped with a vertically arranged slide rail, and a slider is fitted on the slide rail. The front end of the slider is connected to the cutter fixing seat.

[0014] Preferably, to increase the position adjustment capability of the film cutting assembly, a second slider is fixedly provided at the bottom of the mounting frame, and the second slider is sleeved on the second slide rail; the second slide rail is horizontally fixed on the frame of the film applicator.

[0015] Preferably, the bottom of the film cutting blade is provided with a V-shaped cutting edge.

[0016] Briefly describe its working principle:

[0017] The motor drives the rotating shaft to rotate via a reducer. The rotating shaft, through an eccentric wheel and a fisheye bearing connecting rod, causes the cutter holder to move up and down along the slide rail (converting rotary motion into reciprocating linear motion). When the heated aluminum blade fixed in the cutter holder descends to the bottom, a film-cutting action is completed, using the heated blade to cut and melt the film. One rotation of the shaft completes one cutting and resetting action of the heated aluminum blade. This process is highly efficient, with short cutting and resetting times and no noise from pneumatic cylinder operation.

[0018] The beneficial effects of this utility model are:

[0019] Its structure is simple and reasonable, and its operation is stable and reliable; it can cut the membrane strip efficiently without noise; it is easy to use and has high precision. Attached Figure Description

[0025] The servo motor 2 is connected to a horizontally positioned rotating shaft 9 via a reducer 3, thereby driving the rotating shaft 9 to rotate.

[0026] Vertical bearings 8 are fitted at both ends of the rotating shaft 9, and the bottom of the vertical bearings 8 is fixed on the mounting bracket 1;

[0027] The left and right ends of the rotating shaft 9 are respectively connected to the eccentric wheel 5, and the edge of the eccentric wheel 5 is hinged to the top of the fisheye bearing connecting rod 4.

[0028] The cutter fixing seat 6 is horizontally arranged, and its left and right ends are respectively hinged to the bottom ends of the fisheye bearing connecting rod 4;

[0029] The heated aluminum blade 7 is horizontally positioned and fixed to the bottom of the cutter fixing base 6;

[0030] The heated aluminum blade 7 includes a blade holder 71, a cutting blade 72, a heating rod 73 (electric heating rod), and a thermocouple 74. The thermocouple 74 is a temperature sensor; its core principle is to convert a temperature signal into a tiny voltage signal, thereby determining the temperature of the object being measured (the heated aluminum blade 7) by measuring this voltage value. The cutting blade 72 is vertically positioned and fixed to the bottom of the blade holder 71. The blade holder 71 has a horizontally positioned cavity in the middle, penetrating the left and right end faces of the blade holder 71; the heating rod 73 is horizontally positioned and passes through the cavity.

[0034] A conveying assembly is horizontally positioned below the mounting frame 1. The conveying assembly is used to transport the tile after it has been coated with film. A single tile is conveyed backward on the conveying assembly. After the film is coated, it passes through a film cutting assembly (the film strip is a long strip attached to several tiles). The film cutting assembly cuts the film strip so that its size is compatible with or slightly larger than the size of the tile.

[0035] Preferably, a protective cover 14 is fitted on the outer side of the fisheye bearing connecting rod 4 and the eccentric wheel 5.

[0036] Briefly describe its working principle:

[0037] The motor drives the rotating shaft 9 to rotate via the reducer 3. The rotating shaft 9, through the eccentric wheel 5 and the fisheye bearing connecting rod 4, causes the cutter fixing seat 6 to move up and down along the slide rail 10 (converting rotary motion into reciprocating linear motion). When the heated aluminum blade 7, fixed to the cutter fixing seat 6, descends to the bottom, a film cutting action is completed, using the heated blade to cut and melt the film. With one rotation of the rotating shaft 9, the heated aluminum blade 7 completes one cutting and resetting action. This process is highly efficient, with short cutting and resetting time and no noise from cylinder operation.
