Description

Technical Field

[0001] This utility model relates to the technical field of film slitting, specifically a film slitting machine for film production. Background Technology

[0002] Thin films generally refer to sheet-like materials with a thickness between a few micrometers and a few millimeters. They are widely used in the fields of electronics, energy, optics, packaging, and food. They have advantages such as being lightweight and portable, multifunctional, energy-saving, and environmentally friendly. In the production process of thin films, slitting machines are usually required to cut the films into appropriate widths.

[0003] Existing film slitting machines are indispensable equipment in the film production process, used to slit wide films into narrow films of the required size. They are widely used in packaging, printing, electronics, pharmaceuticals and other industries. They generally consist of an unwinding device, a cutting device and a winding device. The wide film is released and unfolded, cut into narrower films by the cutting device, and then wound up by the winding device. During winding, a sleeve is usually put onto the winding roller so that the film is wrapped around the sleeve. However, it is not convenient to limit the sleeve during the winding process, and it is not convenient to adjust and fix when using sleeves of different widths. To solve these problems, we provide a film slitting machine for film production. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a film slitting machine for film production. By setting components such as a winding roller and stops, a sleeve is fitted onto the outer surface of the winding roller. Two pop-out stops block both ends of the sleeve to prevent slippage. When different lengths of sleeves are needed, rotating the knob drives the inner rotating cylinder inside the winding roller to rotate, thereby driving multiple elastic mechanisms and stops to rotate. The six-position adjustable stop allows two stops with different spacings to pop out, thus changing the spacing between the stops to accommodate sleeves of different lengths. This solves the problem of existing machines being inconvenient to limit the sleeve's position and difficult to adjust and fix when using sleeves of different widths.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a film slitting machine for film production, comprising a slitting machine body, an upper power mechanism and a lower power mechanism being provided on the back of the slitting machine body, and a winding assembly being provided on one side of the upper power mechanism and the upper part of the lower power mechanism for winding the cut film; the winding assembly includes a winding roller, an inner rotating cylinder being rotatably connected inside the winding roller, a fixing rod being fixedly connected to the end of the inner rotating cylinder, and a plurality of staggered elastic mechanisms being provided on the outer surface of the fixing rod, a stop being provided at the end of the elastic mechanism, the outer surface of the stop being slidably connected to the inner rotating cylinder, and the outer surface of the stop also being slidably connected to the winding roller.

[0008] Furthermore, a rotating knob is fixedly connected to the end of the inner rotating cylinder, and the end of the fixed rod is also fixedly connected to the rotating knob.

[0009] Furthermore, the elastic mechanism includes a fixed cylinder, one end of which is fixedly connected to a fixed rod, and a sliding cylinder is slidably connected to the inner wall of the fixed cylinder, one end of which is fixedly connected to a stop block.

[0010] Furthermore, a spring is fixedly connected to the inner wall of the fixed cylinder, and the end of the spring away from the fixed cylinder is fixedly connected to the sliding cylinder.

[0011] Furthermore, the upper power mechanism includes a fixed plate, one side of which is fixedly installed with the slitting machine body, and a first motor is fixedly installed on one side of the fixed plate. The output end of the first motor is fixedly connected to a first transmission rod, the outer surface of the first transmission rod passes through the fixed plate, and one end is fixedly connected to the winding roller.

[0012] Furthermore, the lower power mechanism includes a base plate, one side of which is fixedly installed with the slitting machine body. Two support plates are fixedly connected to the upper surface of the base plate, and a second transmission rod is rotatably connected to the upper part of the support plate. The two ends of the second transmission rod are respectively fixedly connected to two winding rollers.

[0013] Furthermore, a second motor is fixedly installed on the upper surface of the base plate, and the output end of the second motor is connected to the second transmission rod.

[0014] (iii) Beneficial effects:

[0015] Compared with existing technologies, this film slitting machine for film production has the following advantages:

[0016] I. This film slitting machine for film production, by setting up components such as winding rollers and stops, allows the sleeve to be fitted onto the outer surface of the winding roller. Two pop-out stops block both ends of the sleeve to prevent slippage. When different lengths of sleeves are needed, rotating the knob drives the inner rotating cylinder inside the winding roller to rotate, thereby driving multiple elastic mechanisms and stops to rotate. The six-position adjustable stop allows two stops with different spacings to pop out, thus changing the spacing between the stops to accommodate sleeves of different lengths. This solves the problem of existing machines being inconvenient to limit the sleeve's position and difficult to adjust and fix when using sleeves of different widths.

[0017] 2. The film slitting machine for film production, by setting up components such as an elastic mechanism, allows the fixed cylinder and the sliding cylinder to slide against each other, thereby increasing or shortening the overall length. The spring gives both a stretching elastic force, so that the stop block has a force to move outward. When the stop block moves to the hole on the winding roller, it can pop out at the hole to lock in place. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The first motor 202 and the second motor 304 in this utility model are common electrical devices in the prior art. They have the same model number. During operation, the positive and negative terminals of the power supply of the two motors are connected in parallel to ensure that they receive the same voltage. At the same time, a control switch is used to control the circuit on and off of the two motors simultaneously, so that their rotation speed and frequency are the same. This application will not elaborate on their model number or internal structure.

[0029] like Figure 1-7As shown, this utility model provides a technical solution: a film slitting machine for film production, including a slitting machine body 1. An upper power mechanism 2 and a lower power mechanism 3 are arranged on the back of the slitting machine body 1. A winding assembly is arranged on one side of the upper power mechanism 2 and on the upper part of the lower power mechanism 3 for winding the cut film. The winding assembly includes a winding roller 4, with an inner rotating cylinder 5 rotatably connected inside the winding roller 4. A fixing rod 6 is fixedly connected to the end of the inner rotating cylinder 5. Multiple staggered elastic mechanisms 7 are arranged on the outer surface of the fixing rod 6. A stop block 8 is arranged at the end of the elastic mechanism 7. The outer surface of the stop block 8 is slidably connected to the inner rotating cylinder 5 and also slidably connected to the winding roller 4. The slitting machine body 1 includes an unwinding roller on the front and a cutting component inside. By installing a long film roll onto the unwinding roller, the film is released and passes through the cutting component. The cutting component includes two circular blades, which are fixed by a rod, allowing adjustment of the blade position. A lifting device, such as an electric telescopic rod, is also provided at the top to adjust the position of the blades. The slitting machine body 1 is raised and lowered to install the film, and also includes guide rollers and tensioning components for guiding the film. The slitting machine body 1 adopts a commonly used cutting method. Since the improvement of this application lies in the winding position, the slitting machine body 1 will not be described in detail. The main improvement is in the winding assembly. In this embodiment, there are three winding assemblies, one at the top and two at the bottom, which can divide the film into three parts. The upper part of the winding roller 4 has multiple holes, allowing the stop block 8 to pass through. The inner rotating cylinder 5... Multiple holes are also provided on the upper part, corresponding to the position of the stop 8. Each stop 8 has a spring mechanism 7 at one end, which is used to provide spring force for the stop 8 to move outward. There are twelve stop 8s, which are mirrored with the center of the winding roller 4. The cross-sectional shape of the fixing rod 6 is hexagonal, and two spring mechanisms 7 and stop 8 are provided on each face, which are mirrored with each other. The distance between them is the width of the film to be divided. The outer surface of the winding roller 4 is also provided with protrusions that engage with the outer sleeve, so that the sleeve rotates synchronously with the winding roller 4.

[0030] A rotating knob 9 is fixedly connected to the end of the inner rotating cylinder 5, and the end of the fixed rod 6 is also fixedly connected to the rotating knob 9. By turning the rotating knob 9, the fixed rod 6 and the inner rotating cylinder 5 can be rotated, thereby adjusting to the two stops 8 that are needed, so that they pop out to the outside of the winding roller 4. When no adjustment is needed, the rotating knob 9 can be fixed to the winding roller 4 with bolts, etc., to prevent relative rotation between the rotating knob 9 and the internal components and the winding roller 4 when the winding roller 4 is rotating.

[0031] The elastic mechanism 7 includes a fixed cylinder 701, one end of which is fixedly connected to a fixed rod 6. A sliding cylinder 702 is slidably connected to the inner wall of the fixed cylinder 701. One end of the sliding cylinder 702 is fixedly connected to a stop block 8. A spring 703 is fixedly connected to the inner wall of the fixed cylinder 701. The end of the spring 703 away from the fixed cylinder 701 is fixedly connected to the sliding cylinder 702. The fixed cylinder 701 and the sliding cylinder 702 can slide against each other, thereby increasing or decreasing the overall length. The spring 703 gives both of them an elongating elastic force, so that the stop block 8 has a force to move outward. When the stop block 8 moves to the hole on the winding roller 4, it can pop out at the hole.

[0032] The upper power mechanism 2 includes a fixed plate 201. One side of the fixed plate 201 is fixedly installed with the slitting machine body 1. A first motor 202 is fixedly installed on one side of the fixed plate 201. A first transmission rod 203 is fixedly connected to the output end of the first motor 202. The outer surface of the first transmission rod 203 passes through the fixed plate 201, and one end is fixedly connected to the winding roller 4. The first motor 202 can drive the first transmission rod 203 to rotate, thereby driving the upper winding roller 4 to rotate, so as to wind the film.

[0033] The lower power mechanism 3 includes a base plate 301. One side of the base plate 301 is fixedly installed with the slitting machine body 1. Two support plates 302 are fixedly connected to the upper surface of the base plate 301. A second transmission rod 303 is rotatably connected to the upper part of the support plate 302. The two ends of the second transmission rod 303 are fixedly connected to two winding rollers 4 respectively. The support plate 302 is used to limit and support the second transmission rod 303 to prevent the second transmission rod 303 from shifting. The second transmission rod 303 fixes the two winding rollers 4 located at the lower part.

[0034] A second motor 304 is fixedly installed on the upper surface of the base plate 301. The output end of the second motor 304 is connected to the second transmission rod 303. The second motor 304 drives the second transmission rod 303 to rotate through the belt. It also has auxiliary components such as pulleys, so that the two winding rollers 4 at the bottom can rotate.

[0035] Working principle: When in use, the sleeve is placed on the outer surface of the winding roller 4. The two ends of the sleeve are blocked by two pop-out blocks 8 to prevent the sleeve from sliding. When different lengths of sleeve are needed, the knob 9 is rotated to drive the inner rotating cylinder 5 inside the winding roller 4 to rotate, thereby driving multiple elastic mechanisms 7 and blocks 8 to rotate. The rotation is adjustable in six positions, so that the two blocks 8 with different spacing can pop out, thereby changing the spacing between the blocks 8 to accommodate sleeves of different lengths and to fix sleeves of different lengths.
