A rotating transmission shaft is fixedly connected to the end of the transmission belt away from the cutting motor. The rotating transmission shaft is mounted on the sliding mounting bracket, and a drive screw is rotatably connected to the side of the sliding mounting bracket near the anti-slip tension roller. A horizontal transmission belt is provided between the drive screw and the rotating transmission shaft, and a cutting blade is threaded to the end of the drive screw away from the transmission belt.

[0010] Preferably, the length of the drive screw is longer than that of the leveling roller, and the initial position of the cutting blade is farther than that of the leveling roller in the horizontal direction.

[0011] Preferably, a transmission air chamber is installed on the lower side of the sliding mounting bracket, a wedge-shaped sliding piston is slidably connected in the transmission air chamber, a third return spring is provided between the wedge-shaped sliding piston and the transmission air chamber, a connecting air pipe is fixedly connected to the lower side of the transmission air chamber, a driven air chamber is fixedly connected to the lower side of the connecting air pipe, and a brake piston is slidably connected to the driven air chamber.

[0012] Preferably, the wedge-shaped sliding piston is in a compression fit with the rotating connecting crank.

[0013] Preferably, a brake ratchet is fixedly connected to one end of the leveling roller near the rotating connecting crank, and the brake ratchet is in a limiting engagement with the brake piston.

[0015] Preferably, the sliding brake ring is positioned above the anti-slip tension roller along the central axis of the rotating connecting crank.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention utilizes a combination of structures such as a leveling roller and an anti-slip stretching roller to lay the graphene film. During the laying process, the leveling roller compresses the graphene film against the ground using the elastic force of a compression spring, thus leveling it. The anti-slip stretching roller, acting on the reaction force from the wall, causes a deflection ratchet to slide in the opposite direction. Through the cooperation of the deflection ratchet and the sliding rack, the anti-slip stretching roller rotates clockwise to a horizontal position, thereby compressing the graphene film into an inclined state along the tangent of the leveling roller and the anti-slip stretching roller, facilitating subsequent cutting of the graphene film by a cutting blade.

[0018] This invention, through the cooperation of structures such as a rotating brake block and a deflecting wedge block, when the deflecting ratchet drives the anti-slip tension roller to rotate, during the reset process under the action of the first reset spring, the rotating brake block restricts the rotation of the deflecting wedge block, thereby causing the deflecting wedge block to squeeze the transmission wedge strip downwards, thus separating the deflecting ratchet and the sliding rack frame, and preventing the sliding rack frame from affecting the rotation of the deflecting ratchet.

[0019] This invention, through the combination of a rotating connecting crank and a wedge-shaped sliding piston, compresses the wedge-shaped sliding piston during the sliding process of the rotating connecting crank. This, in turn, causes the brake piston to slide towards the leveling roller through the transmission air chamber and the driven air chamber, thereby restricting the rotation of the brake ratchet and preventing the graphene film under the leveling roller from sliding due to the rotation of the leveling roller.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the present invention provides a cutting device for graphene film for underfloor heating, including a handcart 100, a symmetrically distributed sliding mounting bracket 200 fixedly connected to the handcart 100, a compression collar 204 slidably connected to the sliding mounting bracket 200, a leveling roller 300 rotatably connected between the compression collars 204, a sliding block 201 slidably connected through the sliding mounting bracket 200, a first return spring 202 provided between the sliding block 201 and the sliding mounting bracket 200, a rotating connecting crank 205 rotatably connected to the sliding block 201, an anti-slip stretching roller 400 rotatably connected between the rotating connecting cranks 205, and a compression spring 203 provided between the compression collars 204 and the sliding mounting bracket 200;

[0031] A deflecting ratchet 600 is fixedly connected to the side of the rotating crank 205 away from the sliding mounting bracket 200. A limiting sliding rod 607 is fixedly connected to the side of the sliding mounting bracket 200 near the deflecting ratchet 600. A sliding rack 601 is slidably connected through the limiting sliding rod 607. The sliding rack 601 is meshed with the deflecting ratchet 600. A transmission ring frame 602 is rotatably connected between the deflecting ratchet 600 and the rotating crank 205. A deflecting wedge block 604 is rotatably connected to the transmission ring frame 602. A transmission wedge strip 603 is fixedly connected to the side of the sliding rack 601 near the sliding mounting bracket 200. The transmission wedge strip 603 and the deflecting wedge block 604 are wedge-shaped engaged.

[0032] A horizontal and vertical rotating brake block 605 is fixedly connected to the transmission ring frame 602, and a second return spring 606 is provided between the sliding rack frame 601 and the limiting sliding rod 607.

[0033] The anti-slip stretch roller 400 is longer than the leveling roller 300.

[0034] A cutting motor 500 is mounted on the upper side of the sliding mounting bracket 200. The output shaft of the cutting motor 500 is fixedly connected to a horizontal transmission belt 501. A rotating transmission shaft 502 is fixedly connected to the end of the transmission belt 501 away from the cutting motor 500. The rotating transmission shaft 502 is mounted on the sliding mounting bracket 200. A drive screw 503 is rotatably connected to the side of the sliding mounting bracket 200 near the anti-slip tension roller 400. A horizontal transmission belt 501 is provided between the drive screw 503 and the rotating transmission shaft 502. A cutting blade 504 is threadedly connected to the end of the drive screw 503 away from the transmission belt 501.

[0035] The length of the drive screw 503 is longer than that of the leveling roller 300, and the initial position of the cutting blade 504 is farther than that of the leveling roller 300 in the horizontal direction.

[0036] The above solution involves laying underfloor heating products made of graphene film during installation. These products are typically of fixed size and may require cutting during installation. When cutting is necessary, one end of the graphene film-made underfloor heating product (hereinafter referred to as graphene film) is laid on the ground. The device is then placed on the graphene film. One worker holds the graphene film while another worker pushes the trolley 100, which in turn drives the leveling roller 300 and the anti-slip tension roller 400 forward synchronously. Since the anti-slip tension roller 400 is in front of the leveling roller 300 and is longer than the leveling roller 300, it isolates small stones and other debris that may be present in the construction environment from the leveling roller 300 during the pushing process. At the same time, under the elastic force of the compression spring 203, the compression ring 204 and the leveling roller 300 are made to adhere more tightly to the ground, thus making the graphene film adhere more tightly to the ground.

[0037] When the device is pushed to the wall, the anti-slip tension roller 400 first contacts the wall surface. The reaction force from the wall causes the anti-slip tension roller 400 to slide in the opposite direction. This, in turn, drives the sliding block 201 to slide in the opposite direction synchronously via the rotating connecting crank 205, compressing the first return spring 202. Simultaneously, this compresses the deflection ratchet 600, causing it to slide in the opposite direction. Through the meshing connection between the deflection ratchet 600 and the sliding rack frame 601, the deflection ratchet 600 rotates clockwise simultaneously during the reverse sliding process, thereby... The rotating crank 205 drives the anti-slip stretching roller 400 to rotate synchronously, thereby changing the anti-slip stretching roller 400 from its initial inclined state to a horizontal state. When the sliding block 201 slides to its limit position, the device can no longer move forward. At this time, the graphene film is at the tangent position of the anti-slip stretching roller 400 and the leveling roller 300, forming a triangle with the corner of the wall. The graphene film is fixed by the leveling roller 300 and the anti-slip stretching roller 400, which facilitates the subsequent cutting of the graphene film by the cutting blade 504.

[0038] The cutting motor 500 is then started, driving the drive screw 503 to rotate synchronously via the transmission belt 501 and the rotating transmission shaft 502. This, in turn, moves the cutting blade 504 towards the cutting motor 500, cutting the straightened graphene film. The position of the cutting blade 504 ensures that the cut graphene film is exactly the same length as the leveling roller 300 to the wall edge, saving the time previously required for pre-cutting measurements. After cutting, the operator controls the handcart 100 to move in the reverse direction, which in turn resets the sliding block 201 via the elastic force of the first reset spring 202. As the rotating connecting crank 205 slides along the sliding mounting bracket 200, it drives the transmission ring frame 602 to slide in the same direction, thereby causing the deflection wedge block 604 to deflect in the same direction. Under the action of the transmission wedge 603, the deflection wedge 604 rotates clockwise and is stopped by the horizontally positioned rotation brake block 605. When the deflection wedge 604 moves to the outside of the transmission wedge 603, it returns to a vertical state under the action of gravity. When the cutting is completed, during the process of the first return spring 202 pushing the sliding block 201 to reset, the deflection wedge 604 rotates counterclockwise under the action of the transmission wedge 603, but is stopped by the vertically positioned rotation brake block 605. Then, through the wedge-shaped cooperation between the transmission wedge 603 and the deflection wedge 604, the transmission wedge 603 slides downward, which in turn drives the sliding rack frame 601 to slide downward, so that the sliding rack frame 601 is no longer in contact with the deflection ratchet 600. Then, the deflection ratchet 600 is repositioned by the self-repetition of the anti-slip stretching roller 400 during the reset process.

[0039] like Figure 7 and Figure 8 As shown, a transmission air chamber 700 is installed on the lower side of the sliding mounting bracket 200. A wedge-shaped sliding piston 703 is slidably connected inside the transmission air chamber 700. A third return spring 704 is provided between the wedge-shaped sliding piston 703 and the transmission air chamber 700. A connecting air pipe 702 is fixedly connected to the lower side of the transmission air chamber 700. A driven air chamber 701 is fixedly connected to the lower side of the connecting air pipe 702. A brake piston 705 is slidably connected to the driven air chamber 701.

[0040] The wedge-shaped sliding piston 703 is press-fitted with the rotating connecting crank 205.

[0041] A brake ratchet 706 is fixedly connected to one end of the leveling roller 300 near the rotating connecting crank 205, and the brake ratchet 706 is in a limiting engagement with the brake piston 705.

[0042] A connecting sliding plate 801 is fixedly connected to the side of the rotating connecting crank 205 away from the anti-slip tension roller 400. A sliding brake ring 800 is slidably connected through the connecting sliding plate 801. A fourth return spring 802 is provided between the sliding brake ring 800 and the connecting sliding plate 801.

[0043] The sliding brake ring 800 is located above the anti-slip tension roller 400 along the central axis of the rotating connecting crank 205.

[0044] Using the above scheme: After the device is pushed to the corner and stretches and fixes the graphene film, it slides in the direction of the rotating connecting crank 205, thereby causing the wedge-shaped sliding piston 703 to slide downwards. This pushes the gas in the transmission air chamber 700 into the driven air chamber 701, causing the brake piston 705 to slide towards the anti-slip stretching roller 400. This causes the brake piston 705 to lock the brake ratchet 706, thereby restricting the clockwise rotation of the leveling roller 300. This prevents the graphene film, fixed by the leveling roller 300, from shifting during the cutting process. During the process of the anti-slip stretching roller 400 rotating to a horizontal state, the sliding brake ring 800 is higher than the anti-slip stretching roller 400 along the central axis of the rotating connecting crank 205. This ensures that the anti-slip stretching roller 400 stops rotating under the action of the sliding brake ring 800 when it reaches a horizontal state. Consequently, the graphene film will not slip due to the rotation of the anti-slip stretching roller 400 under the pressure of the roller. This keeps the graphene film in a straight state during the cutting process, making it easier for the cutting blade 504 to cut the graphene film.

[0045] Working principle and usage process of this invention:

[0046] During the installation of underfloor heating, underfloor heating products made of graphene film need to be laid. These products are usually of fixed size and may need to be cut during installation. When cutting is required, one end of the underfloor heating product made of graphene film is first laid on the ground. The underfloor heating product made of graphene film will be referred to as graphene film from now on. Then, this device is placed on the graphene film. Then, one worker holds the graphene film in front while another worker pushes the handcart 100, which in turn drives the leveling roller 300 and the anti-slip tension roller 400 to roll forward synchronously. Since the anti-slip tension roller 400 is in front of the leveling roller 300 and is longer than the leveling roller 300, it isolates small stones and other debris that may be present in the construction environment from the leveling roller 300 during the pushing process. At the same time, under the elastic force of the compression spring 203, the compression collar 204 and the leveling roller 300 are made to fit more tightly to the ground, thereby making the graphene film fit the ground more tightly.

[0047] When the device is pushed to the wall, the anti-slip tension roller 400 first contacts the wall surface. The reaction force from the wall causes the anti-slip tension roller 400 to slide in the opposite direction. This, in turn, drives the sliding block 201 to slide in the opposite direction synchronously via the rotating connecting crank 205, compressing the first return spring 202. Simultaneously, this compresses the deflection ratchet 600, causing it to slide in the opposite direction. Through the meshing connection between the deflection ratchet 600 and the sliding rack frame 601, the deflection ratchet 600 rotates clockwise simultaneously during the reverse sliding process, thereby... The rotating crank 205 drives the anti-slip stretching roller 400 to rotate synchronously, thereby changing the anti-slip stretching roller 400 from its initial inclined state to a horizontal state. When the sliding block 201 slides to its limit position, the device can no longer move forward. At this time, the graphene film is at the tangent position of the anti-slip stretching roller 400 and the leveling roller 300, forming a triangle with the corner of the wall. The graphene film is fixed by the leveling roller 300 and the anti-slip stretching roller 400, which facilitates the subsequent cutting of the graphene film by the cutting blade 504.

[0048] The cutting motor 500 is then started, driving the drive screw 503 to rotate synchronously via the transmission belt 501 and the rotating transmission shaft 502. This, in turn, moves the cutting blade 504 towards the cutting motor 500, cutting the straightened graphene film. The position of the cutting blade 504 ensures that the cut graphene film is exactly the same length as the leveling roller 300 to the wall edge, saving the time previously required for pre-cutting measurements. After cutting, the operator controls the handcart 100 to move in the reverse direction, which in turn resets the sliding block 201 via the elastic force of the first reset spring 202. As the rotating connecting crank 205 slides along the sliding mounting bracket 200, it drives the transmission ring frame 602 to slide in the same direction, thereby causing the deflection wedge block 604 to deflect in the same direction. Under the action of the transmission wedge 603, the deflection wedge 604 rotates clockwise and is stopped by the horizontally positioned rotation brake block 605. When the deflection wedge 604 moves to the outside of the transmission wedge 603, it returns to a vertical state under the action of gravity. When the cutting is completed, during the process of the first return spring 202 pushing the sliding block 201 to reset, the deflection wedge 604 rotates counterclockwise under the action of the transmission wedge 603, but is stopped by the vertically positioned rotation brake block 605. Then, through the wedge-shaped cooperation between the transmission wedge 603 and the deflection wedge 604, the transmission wedge 603 slides downward, which in turn drives the sliding rack frame 601 to slide downward, so that the sliding rack frame 601 is no longer in contact with the deflection ratchet 600. Then, the deflection ratchet 600 is repositioned by the self-repetition of the anti-slip stretching roller 400 during the reset process.

[0049] After the device is pushed to the corner and stretches and fixes the graphene film, the crank 205 slides in the direction of rotation, causing the wedge-shaped sliding piston 703 to slide downwards. This pushes the gas in the transmission air chamber 700 into the driven air chamber 701, causing the brake piston 705 to slide towards the anti-slip stretching roller 400. The brake piston 705 then engages the brake ratchet 706, thus restricting the clockwise rotation of the leveling roller 300. This prevents the graphene film, fixed by the leveling roller 300, from slipping during the cutting process. During the process of the anti-slip stretching roller 400 rotating to a horizontal state, since the sliding brake ring 800 is higher than the anti-slip stretching roller 400 along the central axis of the rotating connecting crank 205, the anti-slip stretching roller 400 will stop rotating under the action of the sliding brake ring 800 when it reaches a horizontal state. This prevents the graphene film from slipping due to the rotation of the anti-slip stretching roller 400 under the pressure of the roller, and keeps the graphene film in a straight state during the cutting process, which facilitates the cutting blade 504 to cut the graphene film.
