[0002] PVB film is widely used in architectural laminated glass, automotive laminated glass, solar photovoltaic glass, bulletproof glass, and soundproof glass. It offers excellent safety, preventing glass shards from shattering and causing injury. Additionally, it provides sound insulation, UV protection, and can be made in colored or highly transparent forms, giving it optical applications, such as in solar photovoltaics. Currently, most film-cutting devices cut directly on a conveyor belt, which can easily damage the belt, and the fine particles generated during belt cutting can contaminate the film. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a film cutting device that can protect the conveyor belt of a conveyor.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a film cutting device, including a conveyor, a knife holder and a knife; the knife holder includes a knife pad and a first linear reciprocating device; the first linear reciprocating device has a movable end that moves parallel to the conveying direction of the conveyor, and the movable end of the first linear reciprocating device is connected to the knife pad;

[0005] The cutting tool includes a cutter and a second linear reciprocating device. The second linear reciprocating device has a movable end that moves parallel to the conveyor's transmission direction, and the movable end of the second linear reciprocating device is connected to the cutter.

[0006] Furthermore, the cutter holder also includes a support frame and a roller. The support frame is supported below the conveyor belt of the conveyor. The roller and the cutter pad are disposed on the support frame. The cutter pad is located above the roller. The conveyor belt of the conveyor passes under the roller so that the conveyor forms two spaced transmission surfaces. The movable end of the first linear reciprocating device is connected to the support frame.

[0007] Furthermore, the blade pad includes a support portion, a transition portion, and a mounting portion connected in sequence. The top surface width of the support portion is greater than the width of the transition portion. The conveyor belt of the conveyor passes under the support portion. The mounting portion is connected to the support frame.

[0008] Furthermore, the top surface width of the support portion is 50mm to 70mm, and the width of the transition portion is 10mm to 20mm.

[0009] Furthermore, the connection surface between the support portion and the transition portion is an arc surface.

[0010] Furthermore, the top surface of the blade pad is provided with a blade groove.

[0011] Furthermore, the support surface of the support frame is provided with multiple vacuum adsorption holes, and the conveyor belt of the conveyor is provided with multiple through holes that can communicate with the vacuum adsorption holes.

[0012] Furthermore, the cutting tool also includes a third linear reciprocating device and a fourth linear reciprocating device; the third linear reciprocating device is used to drive the cutting tool to move along the width direction of the conveyor, and the fourth linear reciprocating device is used to drive the cutting tool to move along the vertical direction.

[0013] Furthermore, the cutter is an ultrasonic vibrating cutter.

[0014] The beneficial effects of this invention are as follows: By adding a blade pad to the conveyor, the blade acts directly on the blade pad rather than the conveyor belt surface when cutting the PVB film, thus effectively avoiding damage to the conveyor belt by the blade. Simultaneously, a first linear reciprocating device drives the blade pad to move, and a second linear reciprocating device drives the blade to move, achieving follow-up cutting.

[0023] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0024] Please refer to Figures 1 to 3 As shown, this utility model discloses a film cutting device, including a conveyor 1, a knife holder 2, and a knife 3; the knife holder 2 includes a knife pad 21 and a first linear reciprocating device 22; the first linear reciprocating device 22 has a movable end that moves parallel to the transmission direction of the conveyor 1, and the movable end of the first linear reciprocating device 22 is connected to the knife pad 21; the knife 3 includes a cutter 31 and a second linear reciprocating device 32, the second linear reciprocating device 32 has a movable end that moves parallel to the transmission direction of the conveyor 1, and the movable end of the second linear reciprocating device 32 is connected to the cutter 31.

[0025] Working principle: The blade pad 21 is placed on the conveyor 1, so that when the cutter 31 of the cutter 3 makes its downward cut, the blade of the cutter 31 acts on the blade pad 21, thereby protecting the conveyor belt of the conveyor 1. At the same time, during the film cutting process, the first linear reciprocating device 22 drives the blade pad 21 to match the transmission speed of the conveyor 1, and the second linear reciprocating device 32 drives the cutter 31 to match the transmission speed of the conveyor 1, so that the cutter 31 and the blade pad 21 are relatively stationary with respect to the PVB film, thereby achieving follow-up cutting.

[0026] The cutting blade 31 can be a laser, saw blade, ultrasonic vibrating blade, or other cutting blade, with an ultrasonic vibrating blade being preferred.

[0027] In some implementations, please refer to Figures 2 to 4 As shown, the cutter holder 2 also includes a support frame 23 and a roller 24. The support frame 23 is supported below the conveyor belt of the conveyor 1. The roller 24 and the cutter pad 21 are disposed on the support frame 23, with the cutter pad 21 located above the roller 24. The conveyor belt of the conveyor 1 passes under the roller 24, so that the conveyor 1 forms two spaced transmission surfaces. The movable end of the first linear reciprocating device 22 is connected to the support frame 23. By using the support frame 23 and the roller 24 to form two spaced transmission surfaces in the conveyor 1, the top surface of the cutter pad 21 can be made as level as possible with the transmission surface of the conveyor 1, thus ensuring cutting accuracy.

[0028] In some implementations, please refer to Figure 3 As shown, the blade pad 21 includes a support portion 211, a transition portion 212, and a mounting portion 213 connected in sequence. The top surface width of the support portion 211 is greater than the width of the transition portion 212. The conveyor belt of the conveyor 1 passes under the support portion 211. The mounting portion 213 is connected to the support frame 23. Limiting the top surface width of the support portion 211 to be greater than the width of the transition portion 212 allows the support portion 211 of the blade pad 21 to have a sufficiently large area facing the cutter 31, and reduces the distance between the two transmission surfaces.

[0029] For preferred options, please refer to [the provided text]. Figure 3As shown, the top surface width of the support portion 211 is B, which is 50mm to 70mm, and the width of the transition portion 212 is C, which is 10mm to 20mm.

[0030] For preferred options, please refer to [the provided text]. Figure 3 As shown, the connection surface between the support portion 211 and the transition portion 212 is an arc surface. This can reduce the gap between the conveyor belt of the conveyor 1 and the blade pad 21.

[0031] In some implementations, please refer to Figure 3 As shown, the top surface of the blade pad 21 is provided with a blade groove 214. The blade groove 214 facilitates the cutting blade 31 to cut the film material.

[0032] In some implementations, please refer to Figure 4 As shown, the support surface of the support frame 23 is provided with a plurality of vacuum adsorption holes 231, and the conveyor belt of the conveyor 1 is provided with a plurality of through holes (not shown in the figure) that can communicate with the vacuum adsorption holes 231. The vacuum adsorption holes 231 and the through holes can be used to adsorb the membrane material onto the conveyor belt of the conveyor 1 to ensure the stability of the membrane material during the cutting process.

[0033] It is worth noting that the vacuum adsorption pore 231 can be an elongated pore or a round pore.

[0034] In some implementations, please refer to Figure 4 As shown, the cutter 3 further includes a third linear reciprocating device 33 and a fourth linear reciprocating device 34; the third linear reciprocating device 33 is used to drive the cutter 31 to move along the width direction of the conveyor 1, and the fourth linear reciprocating device 34 is used to drive the cutter 31 to move in the vertical direction. The cooperation of the second linear reciprocating device 32, the third linear reciprocating device 33, and the fourth linear reciprocating device 34 enables the three-axis movement of the cutter 31.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
