DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] EMBODIMENT

[0025] In order to facilitate the interception of the fixed length of the packing tape and reduce the cost increased by the length measuring equipment, please refer to Figures 1-5 The embodiment provides a kind of packing tape automatic interception device, including the workbench 1 of top opening, the top of workbench 1 is rotatably connected with feeding assembly 2, one side of workbench 1 is installed with the elastic telescopic cutting assembly 3 extending to the inside of feeding assembly 2, feeding assembly 2 includes the annular frame 21 rotatably connected with workbench 1, the inner wall of annular frame 21 is opened with annular groove 22, one side of annular frame 21 is opened with transverse groove 23 communicated with annular groove 22, the inner wall of annular frame 21 is opened with the arc-shaped groove 24 corresponding with transverse groove 23, the outside of annular frame 21 is fixedly connected with multiple anti-skid strips 25.

[0026] In use, the packing belt is in contact with the annular frame 21 from a point outside the annular frame 21, and the position of the contact point on the workbench 1 is defined as the feeding station, and the position of the elastic telescopic cutting assembly 3 is the cutting station. The packing belt moves along the annular frame 21 to the cutting station, and then continues to pull the packing belt downward. The pulling of the packing belt can be manually pulling the packing belt to move, or using a mechanical claw to grab the packing belt and pull it downward. All that is required is to continuously pull the packing belt downward. During the process of pulling the packing belt downward in the cutting station, the packing belt drags the annular frame 21 to continuously rotate. When the transverse groove 23 outside the annular frame 21 rotates to the cutting station, the elastic telescopic cutting assembly 3 cuts the packing belt through the transverse groove 23, and then continues to pull the packing belt to move. After the packing belt drags the annular frame 21 to rotate one circle, the transverse groove 23 outside the annular frame 21 rotates to the cutting station again, and the elastic telescopic cutting assembly 3 cuts the packing belt through the transverse groove 23. The above process is repeated to continuously cut the packing belt. The length of the packing belt cut is the circumference of the annular frame 21. The packing belt of a fixed length can be easily cut according to the size of the annular frame 21. There is no need to equip a length measuring device to monitor the length of the packing belt passing through.

[0027] In order to control the cutting of the packing belt when the annular frame 21 moves to the specified position, referring to Figure 2 and Figure 4 , the elastic telescopic cutting assembly 3 includes a support table 31 fixedly connected with the workbench 1. The support table 31 extends into the interior of the annular frame 21. A cutting head 32 is slidably connected to the top of the support table 31. A spring 33 is fixedly connected between the support table 31 and the cutting head 32. The cutting head 32 includes a sliding block 321 slidably connected with the support table 31. A cutting knife wheel 322 is rotatably connected to the interior of the sliding block 321. One end of the cutting knife wheel 322 extends to the outside of the sliding block 321. A motor 323 for driving the cutting knife wheel 322 to rotate is fixedly connected to the top of the sliding block 321.

[0028] In use, the motor 323 drives the cutting wheel 322 to rotate, the cutting wheel 322 extends into the annular groove 22 and does not cut the annular frame 21, the sliding block 321 slides along the inner wall of the annular frame 21 until the transverse groove 23 on the annular frame 21 moves to the cutting position, at this time, the sliding block 321 slides along the annular frame 21 to the arc-shaped groove 24, the sliding block 321 drives the cutting wheel 322 to move away from the axis of the annular frame 21 by a distance, so that the cutting wheel 322 extends outside the annular frame 21 after passing through the transverse groove 23, the wrapping tape attached to the annular frame 21 is cut off at the cutting position, then the wrapping tape is pulled from the cut end to move, the wrapping tape drives the annular frame 21 to rotate, so that the transverse groove 23 of the annular frame 21 gradually moves away from the cutting position, the sliding block 321 slides out of the arc-shaped groove 24 and drives the cutting wheel 322 to move close to the axis of the annular frame 21 by a distance, so that the cutting wheel 322 moves into the annular groove 22 again, and the above process is repeated, so that the cutting wheel 322 can cut the wrapping tape once after the annular frame 21 rotates one circle, and the purpose of controlling whether to cut the wrapping tape according to the position of the annular frame 21 is achieved.

[0029] In order to facilitate the control of the wrapping tape abutting against the annular frame 21, thereby dragging the annular frame 21 to rotate when the wrapping tape is pulled, referring to Figure 1 and Figure 5 One side of the workbench 1 is fixedly connected with two arc-shaped plates 4, the two arc-shaped plates 4 are slidingly connected with a limiting rod 5 therebetween, the arc-shaped plates 4 and the limiting rod 5 are different shafts, one side of the arc-shaped plate 4 is provided with a track groove 6, both ends of the limiting rod 5 are movably extended into the track groove 6, the limiting rod 5 is externally sleeved with a side plate 7 slidingly connected with the arc-shaped plate 4, one side of the side plate 7 is provided with a bolt 8 movably penetrating through the side plate 7, a winding frame 9 is installed between the supporting legs of the workbench 1, the winding frame 9 is externally sleeved with a wrapping tape 10, and the wrapping tape 10 is slidingly connected with the annular frame 21.

[0030] In use, the arc-shaped plate 4 and the limiting rod 5 are different in axis, the arc-shaped plate 4 is closest to the annular frame 21 at the bottom, when the limiting rod 5 slides to the bottom along the arc-shaped plate 4, the limiting rod 5 abuts against the annular frame 21, first, the limiting rod 5 is slid upward along the arc-shaped plate 4, so that the limiting rod 5 is away from the annular frame 21, then one end of the wrapping tape 10 wrapped on the wrapping frame 9 is passed between the limiting rod 5 and the annular frame 21, then the wrapping tape 10 is pulled to the cutting station after being wound around the annular frame 21, at this time, the limiting rod 5 is moved downward along the arc-shaped plate 4 until the limiting rod 5 extrudes the wrapping tape 10 on the annular frame 21, then the bolt 8 is rotated to fix the limiting rod 5 and the arc-shaped plate 4, at this time, the wrapping tape 10 is pulled downward from the cutting station, the wrapping tape 10 drags the annular frame 21 to rotate, which is convenient for the wrapping tape 10 to pass through the equipment and be fixed, and is convenient for limiting the wrapping tape 10, and can adjust the extrusion degree between the wrapping tape 10 and the annular frame 21, so as to reduce the possibility that the wrapping tape 10 slips on the annular frame 21 and cannot drag the annular frame 21 to rotate.
