Description

Technical Field

[0001] The utility model relates to the field of film rolling devices, in particular to a film rolling device for producing packaging composite films. Background Art

[0002] Packaging composite film is a thin film material formed by laminating multiple layers of materials using a specific process. It typically consists of two or more materials, such as plastic, paper, and aluminum foil, and is produced through bonding or heat-sealing. This composite film offers the advantages of a variety of materials, meeting diverse packaging needs and offering moisture and oxygen resistance and high strength. Composite film is a process where different materials are bonded together physically or chemically. Common composite film processes include hot pressing, wet lamination, and solvent lamination. Each of these processes has its own unique characteristics, resulting in composite films with varying properties and applications. During the composite film production process, the film must be wound.

[0003] Existing roll film processing can generally be divided into two methods. The first is to manually roll the first few layers and then use a machine to roll them to avoid the first few layers from being loose. The second is to glue the ends of the packaging composite film to the roll and then use a machine to roll it, also to avoid the problem of the first few layers being loose. However, the first method has low labor efficiency and there is a possibility of looseness caused by manual winding. Although the second method can avoid the problem of looseness caused by manual winding, it also requires manual gluing of the ends of the roll film. Therefore, the efficiency of the roll film processing is difficult to improve. At the same time, the second method will also affect the use of the first few layers of the roll film, which is not conducive to the user experience. Utility Model Content

[0004] The purpose of the utility model is to provide a film rolling device for producing a packaging composite film, which can improve the stability and convenience of the packaging composite film during film rolling processing.

[0005] In order to solve the above technical problems, the utility model provides a film rolling device for producing packaging composite film, including a roll, a clamping port opened on the side of the roll along the axial direction of the roll, a first positioning component and a second positioning component respectively arranged at both ends of the roll, the first positioning component and the second positioning component having the same structure and being arranged opposite to each other, the first positioning component including a rotating table arranged in a rotating manner, a plurality of positioning rods arranged at intervals along the outer periphery of the rotating table, the positioning rods and the rotating table being rotated to cooperate so that after the plurality of positioning rods are inserted into the inner side of the roll, the inner side of the roll is limited circumferentially by the positioning rods, and a driving block is arranged between the first positioning component and the second positioning component, and guide inclined surfaces are arranged relatively along the circumferential direction at both ends of the driving block, so that when the plurality of positioning rods move along the guide inclined surfaces, the plurality of positioning rods stretch the inner side of the roll.

[0006] Furthermore, a limit ring is provided at the middle position of the driving block along the circumferential direction, so that the limit ring limits the moving stroke of the positioning rod.

[0007] Furthermore, a rolling belt is rotatably provided on one side of the positioning rod close to the reel, both ends of the rolling belt are connected to the positioning rod through a rotating shaft, and the rotation direction of the rolling belt is parallel to the axis of the reel.

[0008] Furthermore, a plurality of convex strips are arranged on the outer side of the rolling belt, and the arrangement direction of the convex strips is parallel to the axis of the reel.

[0009] Furthermore, a first telescopic rod is provided between the side of the rotating table and the driving block in the first positioning assembly, and the first telescopic rod has a first elastic member built in. A second telescopic rod is provided between the side of the rotating table and the driving block in the second positioning assembly, and the second telescopic rod has a second elastic member built in.

[0010] Furthermore, the end of the first telescopic rod is fixedly connected to the driving block.

[0011] Furthermore, the first positioning assembly also includes a movable seat that is movably matched with the rotating table, and the movable seat is movably arranged in the track.

[0012] The beneficial effect of the present invention is that the two ends of the roll are respectively sleeved on the first positioning component and the second positioning component, so that the several positioning rods respectively support and limit the inner sides of the two ends of the roll, and at the same time the end of the packaging composite film is clamped to the clamping port. Since the rotating table is arranged to rotate, the rotation of the rotating table can drive the rotation of the roll, and then cooperate with the external packaging composite film unloading device to make the composite film wound onto the outer circumference of the roll. Since there is no need to manually bond the ends of the composite film or manually perform the winding operation of the first few layers, the stability and efficiency of the composite film roll processing process can be greatly increased.

[0013] At the same time, due to the setting of the driving block and the guide slope, when the end of the composite film is clamped, the rotating table can be controlled to move toward the driving block, so that several positioning blocks are guided and moved along the guide slope on the outer periphery of the driving block. At this time, the end of the positioning rod is guided by the guide slope, so that the positioning rod moves toward the inside of the reel to support it, and then several positioning rods push the reel outward, thereby conveniently opening the clamping port position to facilitate the placement of the end of the composite film into the clamping port. The rotating table is then reset, and the clamping port can be closed to clamp and fix the end of the composite film. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0022] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0024] like Figures 1-6The utility model provides a film rolling device for producing packaging composite film, including a roll 1, a clamping port 2 opened on the side of the roll 1 along the axial direction of the roll 1, a first positioning component and a second positioning component respectively arranged at both ends of the roll 1, the first positioning component and the second positioning component having the same structure and being arranged opposite to each other, the first positioning component including a rotating table 3 arranged in a rotatable manner, a plurality of positioning rods 4 arranged at intervals along the outer periphery of the rotating table 3, the positioning rods 4 and the rotating table 3 being rotatably matched so that after the plurality of positioning rods 4 are inserted into the inner side of the roll 1, the positioning rods 4 limit the circumferential direction of the inner side of the roll 1, and a driving block 5 is arranged between the first positioning component and the second positioning component, and guide inclined surfaces 6 are arranged relatively at both ends of the driving block 5 in the circumferential direction so that when the plurality of positioning rods 4 move along the guide inclined surfaces 6, the plurality of positioning rods 4 stretch the inner side of the roll 1.

[0025] The two ends of the roll are respectively sleeved on the first positioning component and the second positioning component, so that the several positioning rods respectively support and limit the inner sides of the two ends of the roll, and at the same time, the end of the packaging composite film is clamped to the clamping port. Since the turntable is arranged to rotate, the rotation of the turntable can drive the rotation of the roll, and then cooperate with the external packaging composite film unloading device to make the composite film wound onto the outer circumference of the roll. Since there is no need to manually bond the ends of the composite film or manually perform the winding operation of the first few layers, the stability and efficiency of the composite film winding process can be greatly increased.

[0026] At the same time, due to the setting of the driving block and the guide slope, when the end of the composite film is clamped, the rotating table can be controlled to move toward the driving block, so that several positioning blocks are guided and moved along the guide slope on the outer periphery of the driving block. At this time, the end of the positioning rod is guided by the guide slope, so that the positioning rod moves toward the inside of the reel to support it, and then several positioning rods push the reel outward, thereby conveniently opening the clamping port position to facilitate the placement of the end of the composite film into the clamping port. The rotating table is then reset, and the clamping port can be closed to clamp and fix the end of the composite film.

[0027] A torsion spring is provided at the connection between the positioning rod and the rotating platform, so that the positioning rod can maintain its initial position through the torsion spring, and then the positioning rod can be rotated and reset through the torsion spring during the reset process after being guided by the guide inclined surface.

[0028] In one embodiment of the present solution, the unloading device may include a conveyor belt and a cutting structure, so that the composite film can be transported by the conveyor belt and the composite film can be cut by the cutting structure.

[0029] Preferably, a limit ring 7 is provided in the circumferential direction at the middle position of the driving block 5 so that the limit ring 7 can limit the movement stroke of the positioning rod 4 .

[0030] Specifically, after the end of the positioning rod moves along the guide slope, due to the setting of the limit ring, the end of the positioning rod presses against the side of the limit ring, and the positioning rod cannot continue to move, thereby preventing the positioning rod from excessively stretching the reel, causing problems such as breakage or wrinkling of the side of the reel.

[0031] Preferably, a rolling belt 8 is rotatably provided on one side of the positioning rod 4 close to the reel 1 , both ends of the rolling belt 8 are connected to the positioning rod 4 through a rotating shaft, and the rotation direction of the rolling belt 8 is parallel to the axis of the reel 1 .

[0032] Specifically, since the rotation direction of the rolling belt is parallel to the axis of the reel, when several positioning rods are inserted into the inner side of the end of the reel along the axial direction of the reel, the rolling belt can reduce the friction between the side of the positioning rod and the reel. Similarly, when the positioning rod moves along the guide slope, the rolling belt can also reduce friction loss. When the turntable drives the reel to rotate, since the rolling belt cannot rotate along the circumference of the reel, the reel can be stably supported by the positioning rod, thereby ensuring the rotation of the reel.

[0033] Preferably, a plurality of convex strips are arranged on the outer side of the rolling belt 8 , and the arrangement direction of the convex strips is parallel to the axis of the reel 1 .

[0034] Specifically, the convex strips increase the circumferential friction between the rolling belt and the reel, so that when the turntable drives the reel to rotate, the convex strips can increase the friction between the rolling belt and the reel, further improving the rotation stability of the reel.

[0035] Preferably, a first telescopic rod 9 is provided between the side of the rotating table 3 in the first positioning assembly and the driving block 5, and the first telescopic rod 9 has a first elastic member 10 built in. A second telescopic rod 11 is provided between the side of the rotating table 3 in the second positioning assembly and the driving block 5, and the second telescopic rod 11 has a second elastic member 12 built in.

[0036] Specifically, through the pushing action of the first telescopic rod and the second telescopic rod on the two ends of the driving block, the first positioning assembly and the rotating table in the second positioning assembly synchronously drive several positioning rods to approach the driving block, and the first telescopic rod and the second telescopic rod can be used to keep the driving block between the first positioning assembly and the second positioning assembly to avoid the situation where the reel is stretched at different angles. At the same time, through the setting of the first elastic member and the second elastic member, when the rotating table in the first positioning assembly and the second positioning assembly is moved and reset, the end positions of the first telescopic rod and the second telescopic rod can be maintained by the first elastic member and the second elastic member, thereby ensuring the stable position of the driving block.

[0037] Wherein, the first elastic member and the second elastic member adopt a spring structure.

[0038] Preferably, the end of the first telescopic rod 9 is fixedly connected to the driving block 5 .

[0039] Specifically, by fixing the first telescopic rod and the driving block, when the rotating tables in the first positioning assembly and the second positioning assembly move away from each other, the driving block can be driven to move by the first telescopic rod, so that when the reel takes the material, the driving block will not remain in the reel.

[0040] Preferably, the first positioning assembly further includes a movable seat 13 that is movably matched with the rotating platform 3 , and the movable seat 13 is movably arranged in the track 14 .

[0041] Specifically, the movement of the movable seat is controlled by the track, and then the rotating table is controlled to move along the axial direction of the reel to ensure stability during operations such as opening the clamping port and taking the reel.

[0042] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
