Technical Field

[0001] This utility model relates to the field of film cutting machine technology, and in particular to an adjustable film cutting machine. Background Technology

[0002] With the continuous advancement of industrialization, the demand for automated and precision production is increasing, especially in the processing of thin film materials, such as electronics, packaging, food, and pharmaceuticals, where the requirements for cutting precision and efficiency are becoming increasingly stringent. While traditional film cutting machines have solved the problem of film material cutting to some extent, many of them are gradually showing their shortcomings as production demands change, particularly in terms of adaptability, precision, and flexibility, necessitating technological innovation.

[0003] Traditional film cutting machines typically have fixed cutting parameters, such as cutting depth, angle, and speed. These parameters are difficult to adjust flexibly according to the physical properties of different film materials. For example, when processing film materials of different thicknesses, hardness, and softness, traditional film cutting machines often experience problems such as uneven cutting, rapid blade wear, and low cutting efficiency. These problems seriously affect production efficiency and the utilization rate of film materials.

[0023] Example: An adjustable film cutting machine, please see below. Figures 1 to 7As shown, the machine includes a base plate 1, mounting plate 2, film roll 3, rotating shaft 4, motor 5, pulley assembly 6, rotating drum 7, adjusting drum 8, support frame 9, electric push rod 10, cutter 11, cylinder 12, connecting frame 13, connecting plate 14, guide cylinder 15, fastener 16, fixing plate 17, telescopic rod 18, lifting frame 19, adjusting block 20, and conveying drum 21. The base plate 1 serves as the supporting foundation for the entire film cutting machine, bearing all other components. Mounting plates 2 are symmetrically connected to the top left side of the base plate 1. The film roll 3 is rotatably connected between the upper parts of the mounting plates 2 for loading the film material to be cut. The film material is released by rotation for cutting. Rotating shafts 4 are symmetrically arranged between the lower parts of the mounting plates 2. The upper rotating shaft 4 is used for rotation. A motor 5 is mounted on the lower front side of the mounting plate 2 on the rear side. A pulley assembly 6 is connected between the output shaft of the motor 5 and the rear end of the upper rotating shaft 4. The pulley assembly 6 consists of two pulleys and a flat belt. The two pulleys are respectively connected to the output shaft of the motor 5 and the rear end of the upper rotating shaft 4, while the flat belt is sleeved on the two pulleys. A rotating cylinder 7 is rotatably connected between the middle of the two mounting plates 2. An adjusting cylinder 8 is slidably connected between the middle of the two mounting plates 2. The adjusting cylinder 8 is located above the rotating cylinder 7 and is used to assist in the unfolding and positioning of the membrane material. It works with the adjusting cylinder 8 to adjust the tension of the membrane material. A support frame 9 is connected to the top right side of the base plate 1. Electric push rods 10 are symmetrically installed at the front and back of the top of the support frame 9. A cutter 11 is connected between the push rods of the 0. A cylinder 12 is vertically mounted downwards on the upper part of the two mounting plates 2. The piston rod of the cylinder 12 is connected to a connecting frame 13. The connecting frame 13 is connected to the front end of the adjusting cylinder 8. By driving the connecting frame 13 through the cylinder 12, the adjusting cylinder 8 can be moved up and down to adjust the distance between the adjusting cylinder 8 and the rotating cylinder 7, thereby controlling the cutting pressure and tension. Connecting plates 14 are placed on the front and rear sides of the middle of the base plate 1. A guide cylinder 15 is symmetrically rotated between the two connecting plates 14. The left and right sides of the two connecting plates 14 are connected to the base plate 1 by fasteners 16. A fixing plate 17 is connected between the bottom right sides of the two connecting plates 14. Telescopic joints are symmetrically connected to the top right side of the fixing plate 17. A lifting frame 19 is connected between the upper ends of the telescopic rod 18 and the rod 18. A transverse groove is provided in the middle of the lifting frame 19. Adjusting blocks 20 are symmetrically slidably connected in the transverse groove. A transverse groove is also provided on the top left side of the fixed plate 17. The left sides of the two adjusting blocks 20 extend to the left and into the transverse groove on the top left side of the fixed plate 17. The adjusting blocks 20 and the fixed plate 17 are slidably engaged. A conveying cylinder 21 is connected between the two adjusting blocks 20. The conveying cylinder 21 is a telescopic structure design. The conveying cylinder 21 is used to receive the membrane material unfolded from the film roll 3 and convey it to the cutting area. It can also be adjusted according to the width of the membrane material. The guide cylinder 15 is used to guide the path of the membrane material from the film roll 3 to the conveying cylinder 21 to ensure the smooth transmission of the membrane material.

[0024] When the film cutting machine is needed, firstly, the film material to be cut is loaded onto the film roll 3. Next, the telescopic structure of the conveyor cylinder 21 is adjusted according to the width of the film material. This can be achieved by sliding the adjusting block 20, which slides in the transverse groove of the lifting frame 19 and the fixed plate 17, thereby causing the conveyor cylinder 21 to extend and retract, so that its width matches the film material.

[0025] Subsequently, the height of the lifting frame 19 is adjusted using the telescopic rod 18, thereby adjusting the position of the conveyor cylinder 21 to ensure it is correctly positioned within the cutting area. This step ensures that the membrane material can smoothly reach the cutting area during transport.

[0026] Next, cylinder 12 is used to move the connecting frame 13 and the adjusting cylinder 8 up and down. This design allows for adjustment of the gap between the adjusting cylinder 8 and the rotating cylinder 7. This gap can be flexibly set according to the thickness of the membrane material and the required cutting pressure.

[0027] Then, the membrane material is passed under the two rotating shafts 4, through the adjustment area between the rotating drum 7 and the adjusting drum 8. Here, the membrane material is subjected to appropriate tension and adjustment to ensure its smooth transfer to the next stage. Next, the membrane material is guided by the guide drum 15 and finally arrives at the conveyor drum 21.

[0028] At this time, the power is turned on and the motor 5 is started. The motor 5 will drive the rotating shaft 4 and the film roll 3 to rotate through the pulley assembly 6, thereby releasing the film material. The film material is unwound from the film roll 3, and after being guided by the adjustment area and the guide cylinder 15, it is smoothly conveyed to the cutting area by the conveyor cylinder 21.

[0029] When the membrane material reaches the cutting area, the electric push rod 10 is activated. The electric push rod 10 will push the cutter 11 downward to precisely cut the membrane material. After cutting, the electric push rod 10 will drive the cutter 11 to retract, returning the cutter 11 to its initial position, ready for the next cut.

[0030] As needed, motor 5 and electric push rod 10 can be continuously started to achieve continuous cutting of the membrane material. By repeating the above operation, the membrane material cutting task can be completed efficiently.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
