Description

Technical Field

[0001] This utility model relates to the field of film slitting technology, and in particular to a slitting mechanism for film rolls. Background Technology

[0002] Roll slitting usually refers to an automated process or equipment used to cut rolled materials to specific specifications or lengths. This technology is common in industrial production, especially in printing, packaging, and composite materials.

[0003] In the existing slitting mechanism, there are several slitting blades, and the position of the slitting blades can be freely adjusted. However, the slitting blades are generally fixed by screws. When adjusting the position of several slitting blades, the operator needs to tighten multiple screws. This structure is not convenient for quickly adjusting the position of multiple slitting blades.

[0004] Therefore, a slitting mechanism for roll film needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a slitting mechanism for roll film.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A slitting mechanism for roll film includes a slide rail, on which a plurality of slide blocks are slidably disposed, each slide block is fixed with a blade holder, each blade holder is fixed with a slitting blade, and both ends of the slide rail are fixed with fixing plates. A pressing structure is provided on both fixing plates, and an adjustment structure is provided on one of the fixing plates.

[0008] As a preferred embodiment of this utility model, the clamping structure includes two slides, two sliders, a clamping plate, four limiting plates, and two tension springs. The two slides are respectively opened on two fixed plates, the two sliders are respectively slidably disposed in the two slides, the clamping plate is fixed between the two sliders, the four limiting plates are respectively fixed at both ends of the two sliders, one end of the two tension springs is respectively connected to the two fixed plates, and the other end of the two tension springs is respectively connected to the two sliders.

[0009] As a preferred embodiment of this utility model, the adjustment structure includes a rotating shaft, an eccentric wheel, a sleeve wheel, a damping wheel, and a fixed rod. The rotating shaft passes through a fixed plate and is rotatably connected to the fixed plate. The eccentric wheel is fixedly sleeved on the rotating shaft, and the eccentric wheel and the rotating shaft are eccentrically positioned. The sleeve wheel is fixedly sleeved on the rotating shaft. The damping wheel is fixed to the side of the fixed plate, and the damping wheel is in contact with the sleeve wheel. The fixed rod is fixed to the slider.

[0010] In a preferred embodiment of this invention, the eccentric wheel and the fixed rod are positioned directly opposite each other.

[0011] In a preferred embodiment of this invention, the side surface of the slider is in contact with the inner surface of the slide rail.

[0012] As a preferred embodiment of this utility model, both the bushing and the damping wheel are made of rubber material.

[0013] This utility model has the following beneficial effects:

[0014] 1. Quick adjustment of slitting blade position: By turning the knob on the rotating shaft, the operator drives the eccentric wheel to rotate, thereby achieving quick adjustment of the position of several slitting blades through the linkage of the fixed rod, slider and pressure plate. This design makes the adjustment process simple and quick, without having to tighten multiple screws one by one, which greatly improves the adjustment efficiency and ease of operation.

[0015] 2. Easy to operate: During the adjustment process, the staff only needs to pull the slide to adjust its position, without the need for additional complicated tools or skills, which makes daily maintenance and adjustment more intuitive and efficient;

[0016] 3. Reliable fixing: When the pressure plate is pressed down, it can firmly fix the position of several slides and corresponding slitting blades, ensuring that the slitting blades will not move or loosen on their own during use, thus ensuring the stability and consistency of the cutting effect;

[0017] 4. Damping Design: The rotating shaft is equipped with a sleeve wheel and a damping wheel on the fixed plate. They are made of rubber material and keep in contact. Through friction, the rotating shaft is prevented from rotating on its own without human intervention. This design ensures that the eccentric wheel can be stably fixed after being lifted and will not move accidentally, thereby ensuring the accuracy and reliability of the adjustment process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-6A slitting mechanism for rolled film includes a slide rail 1, on which a plurality of slide blocks 2 are slidably disposed. Each slide block 2 is fixed with a blade holder 3, and each blade holder 3 is fixed with a slitting blade 4. Fixed plates 5 are fixed at both ends of the slide rail 1. A pressing structure is commonly provided on the two fixed plates 5. The pressing structure includes two slide rails 61, two sliders 62, a pressing plate 63, four limiting plates 64, and two tension springs 65. The two slide rails 61 are respectively formed on the two fixed plates 5, and the two sliders 62 are respectively slidably disposed in the two slide rails 61. The sides of the sliders 62 are flush with the slide rails 61. The inner surfaces of the slides 61 fit together. A clamping plate 63 is fixed between the two sliders 62. Four limiting plates 64 are fixed to both ends of the two sliders 62. One end of each of the two tension springs 65 is connected to one of the two fixed plates 5, and the other end of each tension spring 65 is connected to one of the sliders 62. One of the fixed plates 5 is equipped with an adjustment structure, which includes a rotating shaft 71, an eccentric wheel 72, a sleeve wheel 73, a damping wheel 74, and a fixing rod 75. The rotating shaft 71 passes through the fixed plate 5 and is rotatably connected to it. The eccentric wheel 72 is fixedly sleeved on the rotating shaft 71. The eccentric wheel 72 is eccentrically positioned with respect to the rotating shaft 71. When the rotating shaft 71 rotates, it drives the eccentric wheel 72 to rotate. When the eccentric wheel 72 rotates, it can press the fixed rod 75, causing the fixed rod 75 to move upward. When the fixed rod 75 moves upward, it can drive the corresponding slider 62 to move upward, which causes the pressure plate 63 to move upward. When the pressure plate 63 moves upward, it can separate from the several slide blocks 2. Without the pressing effect of the pressure plate 63, the several slide blocks 2 can slide freely on the slide rail 1. The sleeve wheel 73 is fixedly sleeved on the rotating shaft 71, and the damping wheel 74 is fixed to the fixed plate. On the side of 5, the damping wheel 74 is in contact with the sleeve wheel 73. Both the sleeve wheel 73 and the damping wheel 74 are made of rubber material. The fixing rod 75 is fixed on the slider 62. The eccentric wheel 72 and the fixing rod 75 are directly opposite each other. When the rotating shaft 71 rotates, it can drive the sleeve wheel 73 to rotate. When the sleeve wheel 73 rotates, it can always be in contact with the damping wheel 74. Under the action of the friction between the sleeve wheel 73 and the damping wheel 74, the rotating shaft 71 will not rotate without human intervention. This design makes it easy for the staff to flexibly adjust and fix the angle of the eccentric wheel 72.

[0027] The specific working principle of this utility model is as follows:

[0028] When using the film slitting mechanism proposed in this utility model, if the positions of several slitting blades 4 need to be adjusted, the operator first rotates a knob at one end of the rotating shaft 71. The knob drives the rotating shaft 71 to rotate, which in turn drives the eccentric wheel 72 to rotate. The eccentric wheel 72 then presses against the fixed rod 75, causing it to move upwards. This upward movement of the fixed rod 75 drives the corresponding slider 62 to move upwards, which in turn moves the pressure plate 63 upwards. When the pressure plate 63 moves upwards, it separates from the several sliding blocks 2. Lacking the pressure of the pressure plate 63, the sliding blocks 2 can slide freely on the slide rail 1. The position of the slide block 2 can be adjusted by directly pulling the slide block 2. After the adjustment is completed, the operator continues to rotate the rotating shaft 71 until the eccentric wheel 72 separates from the fixed rod 75. Without the squeezing of the eccentric wheel 72, the two sliders 62 will move downward under the elastic force of the two tension springs 65, and the pressure plate 63 will also move downward until the pressure plate 63 presses down on several slide blocks 62. At this time, the pressure plate 63 fixes the position of several slide blocks 2, and the position of several slitting blades 4 will also be fixed. In summary, the operator can quickly adjust the position of several slitting blades 4 by controlling the position of the pressure plate 63, without having to tighten multiple screws one by one, making the adjustment convenient and quick.

[0029] In addition, a sleeve wheel 73 is fixedly sleeved on the rotating shaft 71, and a damping wheel 74 is fixed on the fixing plate 5. The sleeve wheel 73 and the damping wheel 74 are in contact with each other, and both the sleeve wheel 73 and the damping wheel 74 are made of rubber material. When the rotating shaft 71 rotates, it can drive the sleeve wheel 73 to rotate. The sleeve wheel 73 can always be in contact with the damping wheel 74 when rotating. Under the action of the friction between the sleeve wheel 73 and the damping wheel 74, the rotating shaft 71 will not rotate without human intervention. This design makes it easy for the staff to flexibly adjust and fix the angle of the eccentric wheel 72. When the eccentric wheel 72 pushes the fixing rod 75 upward, the position of the eccentric wheel 72 will not move easily. In this case, when the staff adjusts the position of several slides 2, the pressure plate 63 will not move downward.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
