[0029] The following is for reference. Figures 1 to 4 This invention describes a film replacement tool according to an embodiment of the present invention.

[0030] The film replacement fixture of this utility model includes a base plate 100, a clamping assembly, and a limiting assembly.

[0031] Reference Figure 1 The base plate 100 is arranged horizontally, and the base plate 100 is a rectangle with a smaller front and rear dimension and a larger horizontal dimension;

[0032] The clamping assembly includes two clamping mechanisms, which are spaced apart on the upper side of the base plate 100. The two clamping mechanisms are referred to as the first mechanism and the second mechanism, respectively. The first mechanism is located on the rear side of the second mechanism. Each clamping mechanism includes a clamping member 200, which is a horizontally arranged strip. One end of the clamping member 200 is connected to the base plate 100 via a hinge 210. The hinge 210 has a hinge axis extending forward and backward, allowing the clamping member 200 to be flipped upward relative to the base plate 100. The other end of the clamping member 200 is connected to the base plate 100 via a detachable structure. With the position of the hinge 210 relative to the detachable structure as left, the hinges 210 of both clamping mechanisms are located at the left end of their corresponding clamping members 200. The detachable mechanisms of both clamping mechanisms are located at the right end of their corresponding clamping members 200. The bottom of the clamping member 200 abuts against the base plate 100.

[0033] The limiting assembly includes multiple limiting members disposed around the lower side of the base plate 100. The limiting assembly is used to fit over the outer side of the top of the horizontally arranged roll film.

[0034] Understandably, the film rolls of automatic packaging machines are generally located on the horizontally extending unwinding rollers. When changing the film rolls, the old film roll needs to be removed from the unwinding roller, and then the new film roll is installed on the unwinding roller. Then, the beginning of the packaging film is pulled out from the new film roll and aligned with the end of the packaging film released from the previous film roll. The beginning of the packaging film pulled out from the new film roll is called the second alignment section 002, and the end of the packaging film released from the previous film roll is called the second alignment section 002.

[0035] The film replacement fixture of this embodiment is used to mate the second mating section 002 with the first mating section 001. The film replacement fixture of this embodiment can achieve the mating of two packaging films through the following steps:

[0036] Step S100: Place the film changing fixture on the top side of the new film from top to bottom.

[0037] In step S200, manipulate the detachable structure of the two clamping members 200 to separate the ends of the two clamping members 200 from the base plate 100, and flip the two clamping members 200 upward.

[0038] In step S300, the second docking segment 002 is passed from bottom to top across the front side of the base plate 100, then passes from front to back between the clamping member 200 of the second mechanism and the base plate 100, and then laid on the top surface of the base plate 100.

[0039] In step S400, the first docking segment 001 is passed from back to front between the clamping member 200 of the first mechanism and the base plate 100, and then laid on the top surface of the base plate 100, so that the second docking segment 002 and the first docking segment 001 form an overlapping structure 003 on the upper side of the base plate 100.

[0040] Step S500: Move the second docking segment 002 and / or the first docking segment 001 so that the markings on the second docking segment 002 overlap with the markings on the first docking segment 001.

[0041] In step S600, the two clamping members 200 are flipped downwards so that the clamping member 200 of the second mechanism clamps the second docking section 002 and the clamping member 200 of the first mechanism clamps the first docking section 001. The detachable structure of the two clamping members 200 is manipulated so that the ends of the two clamping members 200 are connected to the base plate 100.

[0042] In step S700, the overlapping structure 003 is cut laterally, so that the second docking section 002 is separated into a second docking part and a second loss part, and the first docking section 001 is separated into a first docking part and a first loss part. The second docking part is connected to the packaging film released from the new roll of film, and the first docking part is connected to the packaging film released from the previous roll of film.

[0043] Step S800: Use tape to connect the second mating part and the first mating part.

[0044] Step S900: Remove the roll film and replace the tooling.

[0045] The device features a limiting component that allows the film changing fixture to be stably placed on top of the film roll, facilitating the subsequent docking of the two packaging films. A clamping component allows workers to align the two packaging films and then use two clamping mechanisms to secure them before bonding, preventing changes in their relative positions during bonding and simplifying the process.

[0046] In some embodiments of this utility model, the base plate 100 is provided with a laterally extending cutting groove 101, which is disposed between two clamping members 200. The cutting groove 101 is recessed downward from the upper surface of the base plate 100; in step S400, the overlapping structure 003 is disposed on the upper side of the cutting groove 101, so that in step S700, the operation of cutting the overlapping structure 003 laterally can be performed by using a cutter to cut along the cutting groove 101, which facilitates the cutting operation.

[0047] In some embodiments of this utility model, the detachable structure includes a snap-fit ​​member 223 and a snap-fit ​​seat. The snap-fit ​​member 223 is rotatably mounted on the clamping member 200 via a vertically arranged first rotating shaft 221. The snap-fit ​​seat is mounted on the base plate 100. The snap-fit ​​member 223 and the snap-fit ​​seat are rotatably snapped together. The clamping member 200 is provided with a handwheel 220 for rotating the snap-fit ​​member 223. The snap-fit ​​seat can be an oblong hole 102 set in the base plate 100. The lateral dimension of the oblong hole 102 is larger than the front-back dimension. The snap-fit ​​member 223 is set at the bottom of the clamping member 200 and spaced apart from the clamping member 200. The front-back dimension of the snap-fit ​​member 223 is smaller than the front-back dimension of the oblong hole 102. The lateral dimension of the snap-fit ​​member 223 is larger than the front-back dimension of the oblong hole 102 but smaller than the lateral dimension of the oblong hole 102, so that the snap-fit ​​member 223 can move downward through the oblong hole 102. Then, by rotating the handwheel 220 to rotate the snap-fit ​​member 223 ninety degrees, the clamping member 200 and the base plate 100 can be connected. This structure is simple. The operator can control the flipping of the clamping member 200 relative to the base plate 100 by holding the handwheel 220, and can also control the disassembly and assembly connection between the clamping member 200 and the base plate 100. The operation is simple.

[0048] In some embodiments of this utility model, a first rotating shaft 221 is slidably disposed vertically on the clamping member 200, and a first elastic member 222 is connected between the first rotating shaft 221 and the clamping member 200. The first elastic member 222 is used to drive the clamping member 200 to move downward relative to the first rotating shaft 221. This gives the clamping member 200 a tendency to move downward and press the packaging film, resulting in better clamping and positioning of the packaging film. Simultaneously, the first elastic member 222 can drive the first rotating shaft 221 to move upward relative to the clamping member 200, making the connection between the snap-fit ​​member 223 and the snap-fit ​​seat more compact and less prone to loosening. (Referring to...) Figure 4 The first rotating shaft 221 extends vertically through the clamping member 200. The handwheel 220 is fixedly installed at the top of the first rotating shaft 221. The snap-fit ​​member 223 is fixedly installed at the bottom of the first rotating shaft 221. The first elastic member 222 is a spring. The first elastic member 222 is sleeved on the outside of the first rotating shaft 221, and the two ends of the first elastic member 222 abut against the handwheel 220 and the clamping member 200 respectively, thereby realizing the linkage between the handwheel 220 and the snap-fit ​​member 223 and the first elastic member 222 applying a downward force to the clamping member 200.

A hinge 210 and a detachable structure are respectively disposed at both ends of the rigid pressure strip, and the elastic edge 230 is disposed at the bottom of the rigid pressure strip and abuts against the base plate 100. The elastic edge 230 can be a rubber material component or other suitable elastic material component, while the rigid pressure strip is a metal material component; thus, the clamping member 200 is not easily bent, has a strong structure, and at the same time has a good effect on clamping the packaging film and is not easy to scratch the packaging film.

[0050] In some embodiments of this utility model, both limiting members are referred to as first members 310. Both first members 310 are horizontally arranged strips, and are respectively connected to the front edge and rear edge of the base plate 100. The base plate 100 can be a metal plate, and the first members 310 can be formed by bending the edge of the base plate 100 downwards; this structure is simple and adaptable to the horizontally arranged roll film.

[0051] In some embodiments of this utility model, the two limiting members are referred to as the third member 330 and the fourth member 340, respectively.

In use, the position of the slide block 341 can be adjusted so that the third piece 330 and the fourth piece 340 abut against the two ends of the film roll along the axial direction of the film roll, and then the locking element is used to lock the slide block 341 to fix the position of the fourth piece 340. The film roll changing fixture can then be stably placed on the film roll, and it is also suitable for film rolls of different sizes.

[0052] In some embodiments of this utility model, the fourth piece 340 is slidably disposed on the slide block 341 along the lateral direction, and a second elastic member 344 is connected between the fourth piece 340 and the slide block 341. The second elastic member 344 is used to drive the fourth piece 340 to move closer to the third piece 330 to clamp the film roll; wherein, two slide rods are provided on the right side of the fourth piece 340, both slide rods are arranged laterally, the slide rods pass through the slide block 341 from left to right, and a limit block is provided at the right end of the slide rod to prevent the slide rod from sliding to the right and falling off; at least one slide rod is provided with a second elastic member 344, the second elastic member 344 is a spring, the second elastic member 344 is sleeved on the outside of the slide rod and the two ends of the second elastic member 344 abut against the slide block 341 and the fourth piece 340 respectively.
