DETAILED DESCRIPTION

[0025] The embodiment of the utility model provides a die-cutting roller oiling device.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including two equipment support frames 1, a die-cutting roller 3 is arranged between the two equipment support frames 1, a transmission shaft 5 is fixedly connected inside the die-cutting roller 3, both ends of the outer side of the transmission shaft 5 are rotatably sleeved with fixed frames 6, a guide pipe 7 is fixedly connected between the two fixed frames 6, a plurality of oil discharge holes 9 are opened on the outer side of the guide pipe 7, an oil-absorbing cotton 8 is rotatably sleeved on the outer side of the guide pipe 7, a blocking rod 10 is arranged inside the guide pipe 7, and a pressure sensor 18 is fixedly connected to one end of the guide pipe 7.

[0027] When the utility model is in use: two equipment support frames 1 are rotatably connected with support rollers 2, and the support rollers 2 are arranged at the bottom of the die-cutting knife roller 3 to support and limit the die-cutting material. The support rollers 2 are forced to rotate and cooperate with the die-cutting knife roller 3 that is forced to rotate to complete the die-cutting processing work. Mounting seats 4 are rotatably sleeved on both ends of the transmission shaft 5. The mounting seats 4 are arranged inside the equipment support frame 1 to limit the position of the transmission shaft 5, so that the die-cutting knife roller 3 is limited and installed inside the equipment support frame 1.

[0028] The oil-absorbing cotton 8 is arranged on one side of the top of the die-cutting roller 3. The oil-absorbing cotton 8 rotatably installed on the outside of the guide tube 7 absorbs oil. During the rotation of the die-cutting roller 3, the oil-absorbing cotton 8 is also driven to rotate. At the same time, the oil-absorbing cotton 8 smears oil on the outside of the die-cutting roller 3 to prevent the sticky die-cutting material from sticking to the outside of the die-cutting roller 3, resulting in wrinkles and ruptures in the die-cutting material, thereby reducing economic losses and ensuring the processing quality of the die-cutting material by the die-cutting roller 3.

[0029] The fixed vertical plate 11 fixedly connected at one end of the blocking rod 10 is fixedly connected to the inside of the guide tube 7, so when the blocking rod 10 is installed in the guide tube 7, there is a certain distance between the blocking rod 10 and the inner wall of the guide tube 7, and the multiple oil drain holes 9 opened on the outside of the guide tube 7 are all arranged on the outside of the blocking rod 10, thereby reducing the amount of oil stored in the guide tube 7 and controlling the amount of oil supplied to each position of the oil-absorbing cotton 8 by the guide tube 7 through the multiple oil drain holes 9 at one time, avoiding the situation where the oil-absorbing cotton 8 drips oil due to excessive oil, reducing resource waste, avoiding oil dripping onto the die-cutting material, and avoiding affecting the processing quality of the die-cutting material.

[0030] A mounting tube 12 is rotatably sleeved at one end of the guide tube 7. When the mounting tube 12 infuses oil into the guide tube 7, it will not affect the rotation of the guide tube 7 and the fixed vertical plate 11. A liquid extraction pump 14 is fixedly connected to the bottom end of the telescopic pipe 13 fixedly connected to one end of the mounting tube 12. When the liquid extraction pump 14 fixedly connected to the outside of the equipment support frame 1 is working, the liquid extraction pump 14 extracts oil and outputs it to the inside of the guide tube 7 through the telescopic pipe 13 and the mounting tube 12, and a pressure sensor 18 is fixedly connected to one side of the inside of the guide tube 7. When the pressure sensor 18 detects that the oil in the guide tube 7 exceeds a preset range, the liquid extraction pump 14 electrically connected to the pressure sensor 18 stops working, and the liquid extraction pump 14 starts working again after a period of time. By reciprocating the above work, it can be ensured that the fixed vertical plate 11 continuously supplies oil to the fixed vertical plate 11, ensure that there is oil on the outside of the die-cutting roller 3 to prevent the die-cutting material from sticking, and control the oil cost investment.

[0031] Since the fixed frame 6 to which the guide tube 7 is fixedly connected is rotatably installed together with the transmission shaft 5, the bottom of the fixed blocks 15 rotatably sleeved at both ends of the outer side of the guide tube 7 is fixedly connected with telescopic rods 16, and the telescopic rods 16 fixedly connected to the equipment support frame 1 can be extended and retracted, and the telescopic pipe 13 fixedly installed by the liquid pump 14 can also be extended and retracted, so the guide tube 7 and the transmission shaft 5 can be adjusted up and down at the same time to ensure that the fixed vertical plate 11 contacts one side of the die-cutting roller 3 to apply oil to the outer side of the die-cutting roller 3. The fixed block 15 where the telescopic rod 16 is installed and limited cannot rotate, so that the guide tube 7 cannot be driven by the transmission shaft 5 to rotate synchronously, avoiding the guide tube 7 affecting the normal operation of the die-cutting roller 3.

[0032] Storage grooves 17 are provided on both sides of the top of the equipment support frame 1, and the telescopic rod 16 is set inside the storage groove 17 to reduce the space occupied by the telescopic rod 16, control the volume of the oiling device composed of the equipment support frame 1, the guide pipe 7, the fixed block 15, the telescopic rod 16, the fixed vertical plate 11 and other structures, and reduce the equipment footprint.
