Description

Technical Field

[0001] This utility model relates to the field of breathable membrane production technology, specifically a breathable membrane production edge cutting and rolling device. Background Technology

[0002] According to Chinese Invention Publication No. CN212825602U, a breathable membrane production edge-cutting and rolling device is disclosed, including a rolling rod. A breathable membrane is disposed on the outer surface of the rolling rod. A first side plate and a second side plate are respectively disposed on the outer surfaces of both ends of the rolling rod. A drive motor is fixedly connected to one outer surface of the second side plate. An installation structure is disposed inside the rolling rod. A knife holder rod is disposed at the upper end of the rolling rod. A cutting blade is fixedly connected to the outer surface of the knife holder rod. Both outer surfaces of the knife holder rod are provided with a blade adjustment structure. This invention, a breathable membrane production edge-cutting and rolling device, has a blade adjustment structure and an installation structure, which can automatically adjust the position according to the thickness of the membrane roll, ensuring that the cutting blade always follows the position of the breathable membrane. This makes the edge-cutting process more convenient, better fixes the rolling rod, facilitates the installation and disassembly of the breathable membrane roll, and brings better application prospects.

[0003] However, the above technical solutions have the following problems: the above solutions can realize the autonomous movement of the cutting blade and the quick disassembly of the film rolling rod, but the permeable membrane production cutting and rolling device in the above solutions is only used for the rolling of a certain width of permeable membrane. When cutting the edges of permeable membranes of different widths, different related devices need to be replaced, which is relatively low in practicality. Moreover, the production of permeable membranes of multiple widths requires the equipment of multiple cutting and rolling devices, which is costly. Therefore, this utility model provides a permeable membrane production cutting and rolling device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a breathable membrane production edge cutting and winding device, which solves the problem that breathable membrane production edge cutting devices can only support a single width of breathable membrane edge cutting, thus limiting the scope of application of the edge cutting device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a breathable membrane production edge-cutting and film-winding device, comprising a film-winding frame, wherein a film-winding mechanism is provided inside the film-winding frame to achieve edge-cutting of the film wound on opposite sides of the film-winding frame, the film-winding mechanism comprising:

[0006] The film winding assembly includes a winding roller that rotates inside the film winding frame, a sliding support rod on the opposite side of the film winding frame, and a sliding assembly between the film winding frame and the support rod to limit the sliding.

[0007] The adjustment component includes a clamping part that slides on the surface of the winding roller, an internal sliding cutting part of the support rod, a limit component between the cutting part and the support rod to restrict sliding, and a synchronization component between the cutting parts to achieve synchronous movement.

[0008] A drive component is provided between the clamping part and the cutting part to achieve synchronous movement.

[0009] Preferably, the sliding assembly includes a sliding groove formed on the surface of the film roll holder, and a sliding spring is fixed between the support rod and the sliding groove.

[0010] Preferably, the clamping part includes a clamping block that slides on the surface of the winding roller, and a moving component is provided between the clamping block and the winding roller to restrict movement. The clamping block has a sliding clamping rod inside it via a sliding component.

[0011] Preferably, the moving assembly includes a moving shaft fixed to the surface of the clamping block, and the surface of the winding roller is provided with a moving groove.

[0012] Preferably, the limiting assembly includes a limiting rod that slides inside the device block in the cutting section, the surface of the supporting rod is provided with a limiting groove, and one end of the limiting rod is fixed with a limiting spring.

[0013] Preferably, the synchronization assembly includes a synchronization wheel fixed to the surface of the limiting rod, and the synchronization wheels are connected by a synchronization belt.

[0014] Preferably, the driving assembly includes a rotating groove formed on the surface of the clamping block, and the rotating shaft is fixed on the surface of the cutting part.

[0015] Beneficial effects

[0016] This invention provides a device for cutting and rolling breathable membranes. Compared with the prior art, it has the following advantages:

[0017] (1) The breathable membrane production edge cutting and winding device achieves autonomous movement of the cutting blade by setting a support rod that can slide up and down inside the film winding frame. Based on the support rod and the winding roller, a clamping part and a cutting part are set that can slide and change position on their surface curvature. The rotating groove opened on the surface of the clamping part and the cutting part and the fixed rotating shaft achieve synchronous movement. This ensures that when the winding size inside the film winding frame is changed, the relative distance of the breathable membrane winding roller can be achieved synchronously and quickly, which facilitates the quick adjustment of the applicable objects of the device and increases the applicability of the device.

[0018] (2) The breathable membrane production edge cutting and rolling device has a limit rod that can slide a certain distance inside the equipment block in the cutting part. The gear-shaped protrusion on the surface of the limit rod can slide to limit and guide the rotation and movement of the limit rod by contacting the tooth-shaped limit groove of different depths opened on the surface of the support rod. This can drive the cutting part to move or stop moving inside the support rod, which is convenient for the position of the cutting part to be limited after the subsequent size is determined, and ensures that the position will not change during the cutting process to avoid the dimensional error of the breathable membrane.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides two technical solutions:

[0026] Example 1

[0027] A breathable membrane production edge trimming and winding device includes a film winding frame 1, and a film winding mechanism is provided inside the film winding frame 1 to trim the edges of the film wound on opposite sides of the film winding frame 1. The film winding mechanism includes:

[0028] The film winding assembly 2 has a winding roller 21 that rotates inside the film winding frame 1. The film winding frame 1 is equipped with a motor, which is a three-phase asynchronous motor and is electrically connected to an external power source. The movement of the motor's output shaft is fixed to one end of the winding roller 21 via a coupling. The opposite side of the film winding frame 1 has a sliding support rod 22. A sliding assembly 4 is provided between the film winding frame 1 and the support rod 22 to achieve sliding restriction.

[0029] The adjustment component 3, the clamping part 5 that slides on the surface of the winding roller 21, the internal sliding cutting part 31 of the support rod 22, the cutting part 31 includes a cutting blade and a device block that fixes the cutting blade, a limit component 6 is provided between the cutting part 31 and the support rod 22 to restrict sliding, and a synchronization component 7 is provided between the cutting parts 31 to achieve synchronous movement.

[0030] A drive assembly 10 is provided between the clamping part 5 and the cutting part 31 to achieve synchronous movement;

[0031] Inside the film roll holder 1, a support rod 22 that can slide up and down is provided to enable the autonomous movement of the cutting blade. Based on the support rod 22 and the winding roller 21, a clamping part 5 and a cutting part 31 are provided that can slide and change position according to the curvature of their surfaces. The rotating groove 8 opened on the surface of the clamping part 5 and the cutting part 31 and the fixed rotating shaft 9 achieve synchronous movement. This ensures that when the winding size inside the film roll holder 1 is changed, the relative distance of the appropriate breathable film winding roller can be achieved synchronously and quickly, which facilitates the rapid adjustment of the applicable objects of the device and increases the applicability of the device.

[0032] Example 2

[0033] The main difference from Example 1 is:

[0034] A breathable membrane production edge-cutting and film-winding device includes a sliding assembly 4 with a sliding groove 41 formed on the surface of a film-winding frame 1. A sliding spring 42 is fixed between a support rod 22 and the sliding groove 41. The surface of the support rod 22 is slidably connected to the inner surface of the sliding groove 41. A clamping part 5 includes a clamping block 51 that slides on the surface of a winding roller 21. A moving assembly 52 is provided between the clamping block 51 and the winding roller 21 to restrict movement. A clamping rod 53 slides inside the clamping block 51 via the sliding assembly 4. The moving assembly 52 includes a moving shaft 521 fixed on the surface of the clamping block 51. A moving groove 522 is formed on the surface of the winding roller 21. The surface of the moving shaft 521 is slidably connected to the inner surface of the moving groove 522. A limiting assembly 6 includes a limiting rod 61 that slides inside the equipment block in the cutting part 31. A limiting groove 62 is formed on the surface of the support rod 22. A gear-shaped protrusion exists on the surface of the limiting rod 61. A tooth-shaped protrusion exists inside the limiting groove 62 and on both sides... The widths are inconsistent. One end of the limiting rod 61 is fixed with a limiting spring 63. One end of the limiting spring 63 contacts the bottom surface of the limiting groove 62. The synchronization assembly 7 includes a synchronization wheel 71 fixed to the surface of the limiting rod 61. The synchronization wheels 71 are connected by a synchronization belt 72. The synchronization belt 72 has a large elasticity. The drive assembly 10 includes a rotating groove 8 opened on the surface of the clamping block 51. The surface of the cutting part 31 is fixed with a rotating shaft 9. A limiting rod 61 that can slide a certain distance is set inside the equipment block in the cutting part 31. The gear-shaped protrusion on the surface of the limiting rod 61 can slide and contact the toothed limiting groove 62 of different depths opened on the surface of the support rod 22 to limit and guide the rotation and movement of the limiting rod 61. This can drive the cutting part 31 to move or stop moving inside the support rod 22, which is convenient for the position of the cutting part 31 to be limited after the size is determined. This ensures that the position will not change during the cutting process and avoids dimensional errors caused by the breathable membrane.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] When working, if it is necessary to change the distance between the cutting part 31 and the clamping part 5 to adapt to the winding of other sizes of breathable membrane, the limiting rods 61 on both sides need to be pressed first. Pressing the limiting rods 61 causes the gear-shaped protrusions on the surface to contact the teeth on the surface of the single-sided limiting groove 62. At this time, the limiting rods 61 can rotate. By rotating the limiting rods 61, the cutting part 31 can slide on the surface of the support rod 22 through the rotation of the gears and teeth. The sliding of the cutting part 31 synchronously rotates the shaft 9 and the rotating groove 8, which can drive the clamping part 5 to slide synchronously on the surface of the winding roller 21. When the surface of the clamping part 5 contacts one end of the winding breathable membrane structure, the structure can be tilted and inserted between the clamping rods 53 to achieve fixation. After the structure is fixed, the limiting rods 61 are released. The limiting rods 61 will contact the teeth on both sides under the action of the limiting spring 63 to restrict rotation. At this time, the motor can be started to open the winding of the breathable membrane.
