[0015] Example 1 like Figures 1 to 4 As shown, the present invention proposes a masking film processing device, including a masking film wrapping unit 1, a winding mechanism, and a cutting mechanism. A support frame 101 is provided on one side of the output end of the masking film wrapping unit 1. The masking film wrapping unit 1 is existing technology, which allows the adhesive tape and masking film to be combined and then led out towards the output end of the masking film wrapping unit 1. The specific structure and principle are detailed in patent publication number CN104495442A and will not be repeated here. The winding mechanism is mounted on the support frame 101, and the winding mechanism is constructed by... The bearing is rotatably connected to a limiting roller 103 on one side wall of the support frame 101 and an mounting rod 2. The mounting rod 2 is driven to rotate by a servo motor mounted on the support frame 101. The servo motor has a built-in encoder, which can indirectly measure the winding length of the masking film on the mounting rod 2. The servo motor speed can be adjusted by a controller, and the winding speed parameters can be preset according to the thickness of the masking film. A stop block 201 is installed on the outer circumference of the mounting rod 2 near the support frame 101. A guide roller and a tension roller 102 are set on the support frame 101 and located between the output end of the masking film winding unit 1 and the winding mechanism to tension and guide the combined tape and masking film, thereby improving winding efficiency. The cutting mechanism is set on the support frame 101 and consists of a horizontal moving part 4 installed at the top of the support frame 101, a moving seat 401 that slides and adjusts horizontally along the support frame 101 driven by the horizontal moving part 4, a cutting blade 6 installed at the bottom of the moving seat 401 by a first lifting part, and a pressing seat 5 installed at the top of the support frame 101 by a second lifting part. The moving part 4 is driven by a cylinder or a motor screw. The cutting blade 6 is located diagonally above the limiting roller 103 and the mounting rod 2. The cutting end of the cutting blade 6 is trapezoidal to facilitate better cutting of the masking film. It is arc-shaped relative to the pressing seat 5 and is located directly above the limiting roller 103. The pressing seat 5 has an arc-shaped rubber pad at its abutting end. A second pressure sensor is embedded inside the arc-shaped rubber pad to detect the abutting force of the pressing seat 5 against the limiting roller 103, so as to avoid interference with cutting caused by excessive or insufficient abutting force.

[0016] Furthermore, the stop block 201 and the mounting rod 2 are integrally formed structures. The membrane tube 3 is sleeved on the outer peripheral surface of the stop block 201, the end of the membrane tube 3 abuts against the stop block 201, the inner wall of the membrane tube 3 is in contact with the outer peripheral surface of the stop block 201, a buffer pad is provided on the stop block 201, and anti-slip texture is provided on the outer peripheral surface of the mounting rod 2 to increase the friction at the installation point of the membrane tube 3 and avoid relative sliding interference with winding.

[0017] Furthermore, the cutting blade 6 is made of alloy material and can be detachably installed at the output end of the first lifting component.

[0018] It should be noted that the movable seat 401 is equipped with an infrared distance sensor and an industrial camera to facilitate the determination of whether the cutting blade 6 has moved to a suitable position with the masking film for cutting; the telescopic and lifting parts in this application are all hydraulic rods, and the hydraulic rod model is selected according to the actual use. The controller receives signals from the servo motor encoder, pressure sensor and infrared sensor, and controls the actions of each mechanism in the order of "winding-pause-cutting-unloading-loading-restarting winding".

[0019] In this embodiment, the film cylinder 3 is pushed along the outer peripheral wall of the mounting rod 2 until it abuts against the stop block 201. After the tape and masking film, combined with the masking film winding unit 1, are wound around the guide roller and the limiting roller 103, the film cylinder 3 is then adhered to the outer peripheral wall of the film cylinder 3 at a suitable position around the outer peripheral surface of the limiting roller 103. The controller starts the servo motor to drive the mounting rod 2 to rotate and wind up the masking film. When the masking film is detected to have been wound to a suitable length, the rotation of the mounting rod 2 is paused. At the same time, the controller starts the second lifting component to drive the pressing seat 5 to move downward until the pressing seat 5 presses the corresponding masking film onto the outer peripheral surface of the limiting roller 103. The controller starts the horizontal moving component 4 to drive the moving seat 401 to move towards the masking film. When the cutting blade 6 moves towards the limiting roller 103... When the device moves close to the masking film between the device and the mounting rod 2, the first lifting component is activated by the controller to drive the cutting blade 6 to move down a suitable distance to cut the masking film. At this time, the cut end of the masking film is pressed against the limiting roller 103 by the pressing seat 5. After the cutting blade 6 returns to its initial position by the controller, the film tube 3 with the masking film is pulled out from the mounting rod 2 and a new set of film tubes 3 is inserted. Then, the pressing seat 5 is returned to its initial position by the controller, and the end of the masking film on the limiting roller 103 is pulled to the outer circumference of the film tube 3 for adhesion. The above-mentioned masking film winding work can be repeated. Compared with the traditional method, the winding of the masking film is more accurate and efficient. After winding, the cutting can be completed automatically, further improving the processing efficiency.

[0020] Example 2 like Figure 1 and Figure 3 As shown, the spray masking film processing device proposed in this utility model, compared with the first embodiment, has an abutment seat 8 installed on the side wall of the support frame 101 through a telescopic component. The abutment seat 8 is a rubber seat, and the abutment seat 8 corresponds to a set of blocks 201 near the output end of the support frame 101.

[0021] The cutting mechanism also includes a movable frame 402 and a stabilizing rod 403. The movable frame 402 is C-shaped, with one end mounted on a movable base 401. Two sets of stabilizing rods 403 are provided, and the two sets of stabilizing rods 403 are mounted on the inner wall of the support frame 101. The movable frame 402 is slidably connected to the two sets of stabilizing rods 403. The movable frame 402 is guided by the two sets of stabilizing rods 403 to ensure smooth horizontal sliding. A material feeding seat 7 is installed at the bottom of the movable frame 402 through a third lifting component. The material feeding seat 7 is provided with an arc-shaped material feeding part, which corresponds to a set of stop blocks 201 near the output end of the support frame 101. Furthermore, a first pressure sensor is embedded inside the abutment seat 8 to detect the abutment force of the abutment seat 8 against the membrane cylinder 3 on the mounting rod 2, so as to avoid damage to the membrane cylinder 3 caused by excessive force of the telescopic component; an infrared distance sensor is embedded on the feeding seat 7 and in the arc-shaped feeding part to detect the distance between the feeding seat 7 and the mounting rod 2, so as to avoid large collisions between the feeding seat 7 and the mounting rod 2.

[0022] In this embodiment, when the membrane tube (3) is inserted into the outer circumferential surface of the mounting rod (2), one end of the inner wall of the membrane tube (3) is first inserted into one end of the outer circumferential surface of the mounting rod (2). Then, the telescopic component is activated by the controller to drive the abutment seat (8) to move toward the other end of the membrane tube (3) until the membrane tube (3) is pressed against the stop block (201), which helps the membrane tube (3) to be quickly installed on the mounting rod (2) to complete the feeding of the membrane tube (3). When the horizontal moving component (4) drives the moving seat (401) to move in the direction of the mounting rod (2), when the cutting blade (6) closes the space between the limiting roller (103) and the mounting rod (2), After the masking film is cut, the moving frame (402) drives the material feeding seat (7) to move to the bottom of the mounting rod (2) and close to the stop block (201). The controller starts the third lifting component to drive the material feeding seat (7) to move up to a suitable height so that the mounting rod (2) is located between the arc-shaped material feeding parts. Then, as the horizontal moving component (4) drives the moving seat (401) to return to the initial position, the moving frame (402) drives the material feeding seat (7) to push the film tube (3) on the mounting rod (2) away from the mounting rod (2), which can assist the unloading of the film tube (3) after it has been wound up, and improve the processing efficiency.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
