[0021] Specifically, the roller speed meter 203 and the sound and light alarm 309 are both electrically connected to the PLC controller 302 .

[0022] In this embodiment, by setting up a roller speed meter 203, a PLC controller 302 and an audible and visual alarm 309, when the roller speed meter 203 detects that the rotation speed of the reel roller 405 is lower than or higher than the rotation speed threshold set by the PLC controller 302, the system can automatically trigger the audible and visual alarm 309 to alert the staff.

[0023] Specifically, a connecting seat 401 is provided at the front and rear of one side of the top of the anti-static mat 202 , and a main roll roller 402 is movably provided between the two connecting seats 401 .

[0024] In this embodiment, by providing a connecting seat 401 and a main roll roller 402 , the PVC main roll is put on the main roll roller 402 , and the connecting seat 401 provides stable support for the main roll roller 402 .

[0025] Specifically, a driving roller 403 is provided on one side of the main rolling roller 402 .

[0026] In this embodiment, by providing an active roller 403 , the PVC roll head is wound onto the active roller 403 , and the rotation of the active roller 403 drives the PVC roll head to move.

[0027] Specifically, a heating roller 404 is provided on one side of the active roller 403 .

[0028] In this embodiment, by providing a heating roller 404, the heating rod inside the heating roller 404 heats the PVC coil head when it is in operation, thereby softening it.

[0029] Specifically, a winding roller 405 is provided on one side of the heating roller 404 .

[0030] In this embodiment, a reeling roller 405 is provided and the reels are placed on the reeling roller 405 so as to facilitate reeling of the PVC film.

[0031] When in use, open the inspection door 308, set the speed threshold in the PLC controller 302, close the inspection door 308, first put the PVC main roll on the main roll roller 402, the active roller 403 will drive the PVC roll head to move, the heating roller 404 heats the PVC roll head to make it soft, and then place the sub-roll on the sub-roll roller 405. During the sub-rolling process, the roller tachometer 203 will test the speed of the sub-roll roller 405. After receiving the data from the roller tachometer 203, the PLC controller 302 compares it with the pre-set speed threshold. If it is greater than or less than the set threshold, the PLC controller 302 will send an electrical signal to the sound and light alarm 309, and the sound and light alarm 309 starts to operate, thereby emitting an alarm sound and flashing an alarm light to remind staff to pay attention to abnormal conditions and prevent the sub-roll roller 405 from idling.

[0032] When the PLC controller 302 is operating, the cooling fan 304 is turned on, and the dustproof net 305 will filter the air entering the protective box 301. Dust and impurities are retained on the surface of the dustproof net 305, preventing dust from entering the interior of the protective box 301 and extending the service life of the PLC controller 302. The filtered air enters the protective box 301, and the rotation of the cooling fan 304 will promote the speed of air circulation in the protective box 301, so that the hot air is quickly discharged from the ventilation holes, thereby reducing the internal temperature of the protective box 301 and achieving the purpose of heat dissipation for the PLC controller 302. When the dustproof net 305 needs to be cleaned, the bolt 307 is tightened to release the restriction on the installation frame 306. At this time, the installation frame 306 can be removed and the dustproof net 305 can be cleaned, which provides convenience for the staff. After cleaning, the installation frame 306 is returned to its original position, and the bolt 307 is tightened to fix the installation frame 306 and improve the stability of the dustproof net 305.

[0033] In summary, the PVC protective film production reeling machine is provided with a PLC controller 302 and an audible and visual alarm 309, and a speed threshold is set in the PLC controller 302. When the roller speed meter 203 detects that the speed of the reeling roller 405 is lower than or higher than the threshold, the PLC controller 302 will determine it as an abnormal situation and send an electrical signal to the audible and visual alarm 309. The audible and visual alarm 309 will start immediately after receiving the signal from the PLC controller 302, and the alarm light will start flashing at the same time as the alarm sound, thereby reminding the staff to pay attention to the abnormal situation, so that the staff can check the status of the reeling roller 405 in time and take corresponding treatment measures, thereby enhancing the safety performance of the device, improving work efficiency, and effectively reducing the waste of resources caused by the idling of the reeling roller 405. 6. Bolt 307 and inspection door 308. Open the inspection door 308 to quickly and easily set the parameters of the PLC controller 302, reducing the workload of the staff. When the cooling fan 304 is started, air will be inhaled from the outside through the ventilation holes. The air will first be filtered through the dustproof net 305 to remove dust and other particulate matter. The filtered air then enters the protective box 301. As the air circulates inside the protective box 301 and absorbs heat, the hot air will be discharged through the ventilation holes again, thereby achieving heat dissipation for the PLC controller 302. By tightening the bolt 307, the installation frame 306 and the dustproof net 305 can be removed and the dustproof net 305 can be cleaned. After cleaning, the dustproof net 305 and the installation frame 306 can be installed back to their original positions.
