[0015] Compared with the prior art, the beneficial effect of the present invention is that the transmission motor of the cutting machine with a protective function reverses, and drives the four rotating rods to reverse through the coupling and the transmission assembly to drive the movable limiting roller to abut against the protective film. At this time, the two sides of the protective film are flatly limited by the fixed limiting roller and the movable limiting roller, which solves the problem that the protective film will be folded due to improper unwinding, resulting in the protective film not being in a flat state when cut, with wrinkles, and thus cutting errors.

[0016] 1. The cutting machine with a protective function has a flattening mechanism on both sides of the cutting disk to prevent wrinkles from occurring during the cutting process. The transmission motor is started to drive the four rotating rods to rotate forward through the coupling and the transmission assembly, and then the movable limiting roller is driven to move down to reserve space for operation through the threaded layer on the top of the rotating rod and the threaded groove at the bottom of the support frame, so that one end of the protective film passes through the first mounting frame and the second mounting frame in turn and is fixed to the winding roller.

At this time, both sides of the protective film are flattened and limited by the fixed limiting roller and the movable limiting roller. The cutting machine with a protective function is provided with a flattening mechanism, which can make the protective film in a flat state before and after cutting, thereby preventing wrinkles from occurring, thereby protecting the protective film.

[0017] 2. In this cutting machine with a protective function, when dirt adheres to the surface of the protective film, it will affect the flattening operation of the protective film. When the driving motor on the side of the winding roller drives the winding roller to rotate and pull and rewind the cut protective film, the unwinding roller starts to unwind. At this time, the squeezing roller squeezes the outer side of the protective film upward to preliminarily limit its position. In the process of being pulled, the protective film will contact the movable scraper, and the movable scraper will scrape off the dirt adhered to the surface of the protective film. The scraped dirt enters the collection box along the bottom of the connecting frame for collection. The cutting machine with a protective function is provided with a cleaning mechanism, which can preliminarily clean the protective film before cutting, so as to facilitate the subsequent operation of the flattening mechanism and improve the cutting efficiency.

[0018] 3. The cutting machine with a protective function is designed to facilitate the replacement of the winding roller. After the winding roller is wound up, the plug-in frame is pulled to the side away from the winding roller. At this time, the plug-in frame will squeeze the reset spring and disengage from the plug-in slot. When the plug-in frame is completely flush with the side of the installation slot close to the winding roller, the winding roller is moved to the side where the plug-in frame is located until the plug-in slot is separated from the plug-in block on one side of the coupling. The winding roller can be easily removed. The cutting machine with a protective function is provided with a plug-in frame and a reset spring. The winding roller can be replaced by simply pulling and pushing, and the operation is easy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] 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 without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 3 The utility model provides a technical solution: a cutting machine with a protective function, comprising a cutting machine body 1, a winding roller 2 and a winding roller 3.

[0030] A unwinding roller 2, a winding roller 3 and a cutting disc 4 are provided on the upper side of the cutting machine body 1, and a control box 101 is installed inside the cutting machine body 1. A driving motor 301 is installed on the side of the cutting machine body 1 close to the winding roller 3 and the cutting disc 4. A first mounting bracket 5 and a second mounting bracket 501 are installed on the upper side of the cutting machine body 1, and a flattening mechanism 6 is provided on one side of the first mounting bracket 5 and the second mounting bracket 501. The flattening mechanism 6 consists of a fixed limiting roller 601, a movable limiting roller 602, a support frame 603, a thread groove 604, a thread layer 605, a rotating rod 606, a transmission assembly 607 and a transmission motor 608.

[0031] A fixed limiting roller 601 is installed on the upper side of the first mounting frame 5 and the second mounting frame 501, and a movable limiting roller 602 is provided at the bottom of the fixed limiting roller 601. The two sides of the movable limiting roller 602 are connected to the support frame 603 through a support rod. A thread groove 604 is opened inside the support frame 603, and the thread groove 604 is threadedly connected to the top of the rotating rod 606 through a thread layer 605. The bottom of the four rotating rods 606 are connected to a transmission assembly 607. A transmission motor 608 is installed inside the cutting machine body 1, and the top of the transmission motor 608 is connected to the rotating rod 606 on the adjacent side through a coupling. A limiting frame 7 is provided on the side of the second mounting frame 501 close to the cutting disk 4, and the limiting frame 7 is slidably connected to the support layer 702 through a push spring 701.

[0032] During specific implementation, in order to prevent the protective film from wrinkling during the cutting process, a flattening mechanism 6 is set on both sides of the cutting disk 4, and the transmission motor 608 is started to drive the four rotating rods 606 to rotate forward through the coupling and the transmission assembly 607, and then the movable limiting roller 602 is driven to move down to reserve space for operation through the threaded layer 605 on the top of the rotating rod 606 and the threaded groove 604 at the bottom of the support frame 603. One end of the protective film is passed through the first mounting frame 5 and the second mounting frame 501 in turn and fixed to the winding roller 3. After the plugging is completed, the transmission motor 608 is started again. At this time, the transmission motor 608 is reversed, and the four rotating rods 606 are driven to reverse through the coupling and the transmission assembly 607 to drive the movable limiting roller 602 to abut against the protective film. At this time, the two sides of the protective film are flattened and limited by the fixed limiting roller 601 and the movable limiting roller 602;

[0033] Among them, the transmission assembly 607 is composed of a transmission roller and a transmission belt. When the rotating rod 606 connected to the coupling rotates, it drives the transmission roller installed with it to rotate. At this time, the transmission belt sleeved on the outside of the transmission roller rotates accordingly, driving the remaining transmission rollers to rotate, and the synchronous rotation of the four rotating rods 606 can be completed. At the same time, the internal limit frame 7 pushes the support layer 702 through the push spring 701 to push the protective film upward to avoid leaving any surplus after the installation of the protective film, which affects the cutting work. The cutting machine with protective function is provided with a flattening mechanism 6, which can make the protective film in a flat state before and after cutting to prevent the formation of wrinkles, thereby achieving protection of the protective film.

[0034] See Figure 4 and Figure 5 It can be seen that the bottom of the unwinding roller 2 is in contact with the squeezing roller 8, and the bottom of the squeezing roller 8 is plugged into the through hole inside the mounting plate 801 through the sliding rod 802. A limit plate 804 is installed at the bottom of the sliding rod 802, and the upper side of the limit plate 804 is connected to the mounting plate 801 through the squeezing spring 803. A cleaning mechanism 9 is provided at the bottom of the unwinding roller 2, and the cleaning mechanism 9 consists of a gas support rod 901, a connecting frame 902, a movable scraper 903, a plug-in rod 904, a connecting spring 905 and a collection box 906. The bottom of the gas support rod 901 is connected to the cutting machine body 1, and the top of the gas support rod 901 is rotatably connected to the movable scraper 903 through the connecting frame 902. One side of the movable scraper 903 is installed with the connecting spring 905 inside the connecting frame 902 through the plug-in rod 904. One side of the cutting machine body 1 is slidably connected to the collection box 906 through a slider and a sliding groove.

[0035] During specific implementation, when dirt adheres to the surface of the protective film, it will affect the flattening operation of the protective film. When the drive motor 301 on the side where the winding roller 3 is located drives the winding roller 3 to rotate to pull and rewind the cut protective film, the unwinding roller 2 starts to unwind. At this time, the squeezing roller 8 squeezes the outer side of the protective film upward to initially limit it. During the process of being pulled, the protective film will contact the movable scraper 903. The movable scraper 903 scrapes off the dirt adhered to the surface of the protective film. The scraped dirt enters the collection box 906 along the bottom of the connecting frame 902 for collection.

[0036] At the same time, a gas support rod 901, a plug-in rod 904 and a connecting spring 905 are set at the bottom of the movable scraper 903. The gas support rod 901 pushes the movable scraper 903 to move up and contact the protective film. The plug-in rod 904 and the connecting spring 905 drive the movable scraper 903 to adjust the fitting angle with the protective film. After the collection is completed, the collection box 906 can be removed for cleaning through the sliding action of the slider and the slide groove. The upper side of the limit plate 804 drives the sliding rod 802 and the squeezing roller 8 to adjust the position through the extrusion spring 803. The cutting machine with protective function is provided with a cleaning mechanism 9, which can perform preliminary cleaning of the protective film before cutting, facilitate the subsequent operation of the paving mechanism 6, and improve the cutting efficiency.

[0037] See Figure 6 、 Figure 7 and Figure 8 It can be seen that a plug-in slot 302 is provided on one side of the winding roller 3, and a docking slot 304 is provided on the other side of the winding roller 3. One side of the winding roller 3 is connected to the coupling at the output end of the driving motor 301 on the adjacent side through the plug-in slot 302, and the plug-in slot 302 and the plug-in end of the coupling are both cross-shaped. One side of the winding roller 3 is plugged into the plug-in frame 305 through the docking slot 304, and the outer side of the plug-in frame 305 is connected to the cutting machine body 1 through the installation slot 306. The inner side of the plug-in frame 305 is connected to one end of the return spring 307, and the other end of the return spring 307 is installed on the cutting machine body 1.

[0038] When the cam 305 is in the process of being wound up, the cam 306 is pulled out of the way and the cam 307 is released, and the cam 306 is released to the left and right sides of the cam 306. When the cam 305 is in the process of being wound up, the cam 306 is released, and the cam 306 is released. The lower winding roller 3 is connected by the plug-in slot 302 on one side of the new winding roller 3 and the plug-in block 303, and the plug-in frame 305 is loosened. At this time, the plug-in frame 305 slides along the installation slot 306 under the action of the return spring 307 until it is plugged into the docking slot 304 to limit the installation of the new winding roller 3. The cutting machine with protective function is provided with a plug-in frame 305 and a return spring 307. The winding roller 3 can be replaced by simply pulling and pushing, and the operation is easy.

[0039] To sum up, when using the cutting machine with protective function, one end of the protective film is passed through the first mounting bracket 5 and the second mounting bracket 501 in sequence and then fixed to the winding roller 3. After the connection is completed, the transmission motor 608 is started to reverse, and the four rotating rods 606 are driven to reverse through the coupling and transmission assembly 607 to drive the movable limiting roller 602 to abut against the protective film. The driving motor 301 on the side where the cutting disk 4 and the winding roller 3 are located is started through the control box 101 to drive the two to rotate to cut and wind up the protective film respectively.
