Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to specific embodiments and drawings.

Referring to fig. 1-4, a preferred embodiment of the present invention is as follows.

A double-faced adhesive tape winding drum with a cutting device 2 comprises a winding drum main body 1 and the cutting device 2, wherein a rotating shaft 3 is inserted into the side surface of the winding drum main body 1, the rotating shaft 3 is rotatably connected with the winding drum main body 1, pull rods 4 are fixedly arranged at two ends of the rotating shaft 3, and the cutting device 2 is connected with the pull rods 4; cutting device 2 includes fixed block 21, cutting knife 22 and two parallel arrangement's lagging 23, the one end and the 4 elastic connection of pull rod of lagging 23, the other end and fixed block 21 fixed connection, cutting knife 22 card are located on fixed block 21, still are equipped with baffle 5 between two lagging 23, and baffle 5 is located cutting knife 22's below. The double-sided adhesive tape reel of this embodiment, cutting device 2 has been add on reel main part 1, when specifically using, because two lagging 23 and pull rod 4 are elastic connection, elasticity can make the adaptability adjustment according to reality, because of the elasticity between the two, two lagging 23 and fixed block 21 can overlap the outside at the film and hug closely the film, make reel main part 1's rotation more stable, when extracting the sticky tape, make the sticky tape pass the clearance between baffle 5 and the cutting knife 22, when having extracted the sticky tape on reel main part 1, can utilize this cutting knife 22 to cut off the sticky tape, can also make the incision of sticky tape more level when having improved the cutting efficiency of sticky tape, the planarization of the disconnected sticky tape of incision has been improved, thereby the result of use of sticky tape has been guaranteed.

In this embodiment, the cutting blade 22 includes a blade tip 221 and a connecting block 222, the blade tip 221 is fixedly connected to the connecting block 222, the connecting block 222 penetrates through the fixing block 21 and is elastically connected to the fixing block 21, and the blade tip 221 points to the baffle 5. In addition, the length of the cutting knife 22 is less than or equal to the distance between the two straps 23. When the cutting device 2 is used, the connecting block 222 is manually pressed, so that the connecting block 222 moves in the vertical direction by taking the fixing block 21 as a reference, the tool nose 221 is driven to contact with the adhesive tape and supported by the baffle 5, and the adhesive tape is cut. But due to the connection between the connection block 222 and the fixed block 21. The elastic connection is adopted, so that after the connecting block 222 is released, the automatic resetting of the connecting block 222 and the knife tip 221 can be realized due to the elastic force.

In this embodiment, flanges 223 are disposed on two sides of the connecting block 222, a cavity 211 is dug in the fixing block 21, the flanges 223 are disposed in the cavity 211, a first spring 6 is disposed in the cavity 211, and the first spring 6 is disposed below the flanges 223. The purpose that flange 223 set up is in order to make connecting block 222 can not break away from fixed block 21 when removing all the time, and still be equipped with first spring 6 between the diapire in flange 223 and cavity 211, therefore, when pressing connecting block 222, flange 223 can extrude first spring 6 simultaneously, make first spring 6 compression produce elasticity, can effectively cushion cutting knife 22's impact force on the one hand, avoid cutting knife 22 to damage baffle 5, on the other hand is when the sticky tape has been cut, can utilize the elasticity that first spring 6 compression produced to make connecting block 222 and cutting knife 22 automatic re-setting after loosening connecting block 222, be convenient for next cutting.

In this embodiment, a through hole 231 is formed in the sleeve plate 23, a step is formed in the through hole 231, the pull rod 4 is inserted into the through hole 231, a limit block is arranged at one end of the pull rod 4 located in the through hole 231, the pull rod 4 is sleeved with a second spring 7, and the second spring 7 is clamped between the step and the limit block. Also be elastic connection for being connected between pull rod 4 and the lagging 23, pull rod 4 is fixed on pivot 3, and the length of pull rod 4 remains unchanged all the time, and lagging 23 slides from top to bottom along pull rod 4, and because the cover is equipped with second spring 7 on pull rod 4, second spring 7 provides an elasticity for lagging 23 makes lagging 23 can receive one throughout and pulls the power, thereby drives fixed block 21 and laminates the surface at the film all the time, has guaranteed fixed block 21's stability. It should be noted that the elastic force of the second spring 7 should be as small as possible, so as to avoid the reel body 1 from being unable to rotate or being unsmooth in rotation, and ensure that the adhesive tape can be smoothly drawn out.

In the present embodiment, the fit between the tie bar 4 and the through hole 231 is a clearance fit. The clearance fit can make the rotation between the pull rod 4 and the reel body 1 smoother and more stable.

In the embodiment, the surface of the baffle 5 is coated with a layer of anti-sticking coating, and the anti-sticking coating is a nano anti-sticking coating. Since the tape is always between the baffle 5 and the cutter 22 when being extracted and the side of the tape not attached with the release paper always faces the baffle 5 when the tape is cut off, the baffle 5 needs to have a certain anti-sticking performance in order to avoid the tape being attached to the baffle 5.
