Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape production, in particular to an adhesive tape production cutting and truncation device. Background Art

[0002] Adhesive tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together through bonding. During the production process of adhesive tape, a slitting device is used to cut the entire roll of tape into multiple strips, and a cutting device is used to cut the tape off after it is completely wrapped around the outside of the paper tube.

[0003] Authorization announcement No. CN215920698U discloses a tape cutting device for tape production, including a main knife shaft, which is convenient for slitting the tape by installing the main knife shaft, and the main knife shaft includes two circular shafts. The utility model is convenient for adjusting the distance between the two semi-circular rings through the tension bolts, thereby achieving contact or separation between the anti-slip pad and the shell, and thus facilitating personnel to achieve position adjustment by sliding the two semi-circular rings on the connecting shaft, thereby achieving distance adjustment between the blades.

[0004] The disadvantage of the existing tape cutting device for tape production is that the tape can only be cut by a blade fixed on the mounting block, and the tape cannot be cut after it is completely wound around the outside of the paper tube. Therefore, a tape production cutting and cutting device is proposed. Summary of the invention

[0005] The main purpose of the utility model is to provide a tape production cutting and chopping device, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A tape production cutting and truncation device comprises a first side plate, a second side plate, a structural frame and a cutting assembly, wherein a second side plate is arranged on one side of the first side plate, and a structural frame is welded to one side of the first side plate and the second side plate, vertical poles are equidistantly sleeved through the top of the structural frame, a horizontal plate is fixed to the bottom end of the vertical pole by bolts, a cutting knife is fixed to the bottom of the horizontal plate by a knife seat, a screw rod is rotatably connected to the inside of the first side plate and the second side plate by bearings, an internally threaded slider is sleeved on the outer side of the screw rod, a shaft column is rotatably connected between the internally threaded sliders by bearings, a cutting assembly is equidistantly sleeved on the outer side of the shaft column, and the cutting assembly comprises a ring equidistantly sleeved on the outer side of the shaft column, and an annular cutting knife is welded to the outer side of the ring.

[0008] Furthermore, limiting slide bars are welded on both sides of the first side plate and the second side plate, limiting slide grooves are provided on both sides of the internal thread slider, and the limiting slide bars are located inside the limiting slide grooves.

[0009] Furthermore, a compression spring is sleeved on the outer side of the vertical pole located at the top of the structural frame, and the top end of the vertical pole is connected to a limiting block through a threaded groove; the limiting block can prevent the vertical pole from falling off from the structural frame.

[0010] Furthermore, a slot is provided at the top of the shaft column, and the outer side of the collar located inside the annular cutting knife is connected with a fixing bolt through a threaded groove.

[0011] Furthermore, a rocker plate is provided at the top end of the screw rod through a flat key fixing sleeve, and the rocker plate is located at the top of the first side plate and the second side plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The rocker turns the lead screw to push the threaded slider up and down, so that the annular cutting knife contacts the tape and cuts it during its movement. The sleeve is sleeved on the outside of the shaft column, and the spacing between the annular cutting knives can be moved and adjusted. After the tape is cut and completely wrapped around the outside of the paper tube, the horizontal plate is moved down to cut the tape through the cutting knife. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-3As shown, a tape production cutting and truncation device includes a first side plate 1, a second side plate 2, a structural frame 3 and a cutting assembly 5, wherein the second side plate 2 is arranged on one side of the first side plate 1, and the structural frame 3 is welded to one side of the first side plate 1 and the second side plate 2, and vertical poles 6 are equidistantly penetrated through the top of the structural frame 3, and a horizontal plate 7 is fixed to the bottom end of the vertical pole 6 by bolts, and a cutting knife 8 is fixed to the bottom of the horizontal plate 7 by a knife holder, and the first side plate 1 and the second side plate 2 are both rotatably connected with a screw rod 13 through a bearing, and an internally threaded slider 12 is sleeved on the outer side of the screw rod 13, and a shaft column 4 is rotatably connected between the internally threaded sliders 12 through a bearing, and a cutting assembly 5 is equidistantly sleeved on the outer side of the shaft column 4, and the cutting assembly 5 includes a ring 17 equidistantly sleeved on the outer side of the shaft column 4, and an annular cutting knife 18 is welded to the outer side of the ring 17.

[0020] Among them, Figure 2 As shown, limiting slide bars 15 are welded on both sides of the first side plate 1 and the second side plate 2, and limiting slide grooves 16 are provided on both sides of the internal thread slider 12. The limiting slide bar 15 is located inside the limiting slide groove 16. When the internal thread slider 12 moves up and down, the limiting slide bar 15 slides in the limiting slide groove 16, which can prevent it from rotating with the screw rod 13 without affecting the up and down movement of the internal thread slider 12.

[0021] Among them, Figure 1 As shown, a compression spring 9 is sleeved on the outer side of the vertical rod 6 located at the top of the structural frame 3, and the top of the vertical rod 6 is connected to a limiting block 10 through a threaded groove. The compression spring 9 pushes the vertical rod 6 to move up and reset through the limiting block 10.

[0022] Among them, Figure 1 and Figure 3 As shown, a slot 11 is provided on the top of the shaft column 4, and the outer side of the collar 17 located inside the annular cutting knife 18 is connected with a fixing bolt 19 through a threaded groove. The fixing bolt 19 is tightened so that its bottom end is inserted into the slot 11, so that the collar 17 can be fixed after movement.

[0023] Among them, Figure 2 As shown, a rocker 14 is provided at the top of the screw rod 13 through a flat key fixing sleeve, and the rocker 14 is located at the top of the first side plate 1 and the second side plate 2 . The arrangement of the rocker 14 facilitates personnel to rotate the screw rod 13 .

[0024] It should be noted that the utility model is a tape production cutting and cutting device. When working, the personnel use bolts to install the first side plate 1 and the second side plate 2 on the tape slitting machine, hold the rocker 14 to rotate the screw rod 13, and the screw rod 13 rotates the internal threaded slider 12 to move up and down, adjust the height of the shaft column 4, and make the annular cutting knife 18 on the outside of the ring 17 contact the tape, and drive the tape to move when the slitting machine is working. The tape moves and is cut by the annular cutting knife 18. The personnel rotate and loosen the fixing bolts 19 to move the ring 17, which is convenient for adjusting the spacing between the annular cutting knives 18. Tighten the fixing bolts 19 so that the bottom end is inserted into the card slot 11, and the moved ring 17 can be fixed. After the tape is cut and completely wrapped around the outside of the paper tube, the personnel move down the cross plate 7 to cut the tape through the cutting knife 8. After loosening the cross plate 7, the compression spring 9 pushes the vertical rod 6 and the cross plate 7 to move up and reset through the limit block 10.
