[0002] At present, the expandable slit coil widely used in the packaging field includes a paper core tube and an expandable slit sheet wound around the paper core tube. Multiple parallel cut marks are formed on the expandable slit sheet. Each cut mark is composed of multiple slits arranged at intervals, and the slits of adjacent cut marks are arranged staggeredly; when the expandable slit sheet is stretched in a direction perpendicular to the cut marks, the slits will open and the expandable slit sheet will expand to present a three-dimensional honeycomb shape, which has a buffering effect. Therefore, by wrapping the article with the expanded expandable slit sheet, the article can be well protected.

[0003] Currently, a paper feeder is usually used to stretch the expandable slit sheet of the expandable slit coil, so that the expandable slit sheet expands; however, in the existing paper feeder, generally two sets of rollers with different rotation speeds are used to stretch the expandable slit sheet, and each set of rollers includes two rollers arranged opposite to each other; due to the different rotation speeds of the two sets of rollers, when the expandable slit sheet passes through the two sets of rollers, the two sets of rollers will stretch the expandable slit sheet to make the expandable slit sheet expand; however, the structural designs of the existing paper feeders are all relatively complex and costly. Summary of the Invention

[0036] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0037] As Figures 1 to 8 shown, the present invention discloses a simple paper feeding machine structure, which is used to enable the expandable slit sheet C1 to expand when people pull the expandable slit sheet C1 on the expandable slit coil C.

[0038] Cooperate with Figures 1 to 8 As shown, a simple paper feeding machine structure of the present invention includes a frame 1, and an engagement component 2 and an adjustment component 3 cooperated with the frame 1; wherein, the frame 1 includes a first support member 11, a second support member 12, and a connecting member 13 connecting the first support member 11 and the second support member 12, and the first support member 11 and the second support member 12 are oppositely arranged; the engagement component 2 includes a first engagement member 21 and a second engagement member 22 for connecting the core tube C2 of the expandable slit coil C, the first engagement member 21 is movably cooperated with the first support member 11, and the second engagement member 22 is cooperated with the second support member 12 and the second engagement member 22 is oppositely arranged with the first engagement member 21; the adjustment component 3 is cooperated with the first support member 11, and the adjustment component 3 is used to drive the first engagement member 21 to move to control the friction force between the first engagement member 21 and the core tube C2 of the expandable slit coil C, and further adjust the rotational damping of the core tube C2 of the expandable slit coil C.

[0039] Cooperate with Figures 1 to 4 As shown, the connecting member 13 of the frame 1 can be a round roller whose two ends are respectively connected to the first support member 11 and the second support member 12 by bolts. The round roller can not only connect the first support member 11 and the second support member 12, but also play a role in guiding and auxiliary tensioning of the expandable slit sheet C1 of the expandable slit coil C. It should be noted that the frame 1 may not be provided with the connecting member 13. In this way, the frame 1 can first adjust the distance between the first support member 11 and the second support member 12 according to the expandable slit coil C to be installed, and then install the first support member 11 and the second support member 12 on the machine table; both the bottoms of the first support member 11 and the second support member 12 may be provided with mounting plates 14, and the first support member 11 and the second support member 12 are fixed to the machine table through the mounting plates 14.

[0040] Cooperate with Figures 1 to 8As shown, the first connecting member 21 of the connecting assembly 2 is used to abut against the core tube C2 of the expandable slit coil C. The first connecting member 21 can be of a hollow structure to reduce the material used for the first connecting member 21. When the adjusting assembly 3 drives the first connecting member 21 to move closer to the second support member 12, the greater the force exerted by the first connecting member 21 on the core tube C2 of the expandable slit coil C along the axial direction of the core tube C2, the greater the frictional force between the first connecting member 21 and the core tube C2 of the expandable slit coil C, and thus the greater the rotational damping of the core tube C2 of the expandable slit coil C. A mating conical surface 211 can be provided on the first connecting member 21, and the mating conical surface 211 is tapered in the direction from the first support member 11 to the second support member 12. The mating conical surface 211 is used to insert into the core tube C2 to abut against the core tube C2. When the adjusting assembly 3 drives the first connecting member 21 to move closer to the second support member 12, the greater the depth of insertion of the mating conical surface 211 into the core tube C2. At this time, the force exerted by the mating conical surface 211 of the first connecting member 21 on the core tube C2 along the axial direction of the core tube C2 and the force exerted by the mating conical surface 211 on the core tube C2 along the radial direction of the core tube C2 are greater. Thus, the frictional force between the first connecting member 21 and the core tube C2 of the expandable slit coil C is greater, making the rotational damping of the core tube C2 of the expandable slit coil C greater.

[0041] fit Figure 1 、 Figure 2 and Figure 6 As shown, the second connecting member 22 of the connecting assembly 2 includes a connecting seat 221 and a connecting block 222 fitted on the end face of the connecting seat 221. The connecting seat 221 of the second connecting member 22 can be fixed to the second support member 21 by screwing or welding. The connecting block 222 of the second connecting member 22 is arranged close to the first support member 11, and the connecting block 222 is used to insert into the core tube C2 of the expandable slit coil C and is rotatably connected to the core tube C2. A relief inclined surface 2221 can be provided on the outer wall of the connecting block 222 of the second connecting member 22, and the relief inclined surface 2221 is tapered in the direction from the second support member 12 towards the first support member 11. Through the insertion inclined surface 2221, it is convenient for the connecting block 222 to be inserted into the core tube C2. The connecting block 222 of the second connecting member 22 can be of an arc-shaped structure, and the radian of the connecting block 222 is greater than 0° and less than or equal to 180°. In this way, the core tube C2 can rotate relative to the second connecting member 22, and it is convenient for the core tube C2 to quickly disengage from the connecting block 222.

[0042] fit Figures 1 to 8As shown, the adjustment assembly 3 includes an adjustment plate 31, an adjustment bolt 32 and a clamping spring 33; wherein the adjustment plate 31 is connected to the first connecting member 21, and a through hole 311 is provided on the adjustment plate 31; the adjustment bolt 32 passes through the through hole 311 of the adjustment plate 31 and is screwed to the first supporting member 11; the clamping spring 33 is sleeved on the screw rod of the adjustment bolt 32, and the two ends of the clamping spring 33 respectively abut against the adjustment plate 31 and the head of the adjustment bolt 32. When the adjustment bolt 32 is rotated forward, the adjustment bolt 31 applies pressure to the adjustment plate 31 through the clamping spring 33, so that the adjustment plate 31 drives the first connecting member 21 to move closer to the second supporting plate 12. Figures 1 to 5 as well as Figure 7 and Figure 8 As shown, the first connecting member 21 can be connected to the adjustment plate 31 through at least one connecting rod 4, and the two ends of the connecting rod 4 are respectively connected to the first connecting member 21 and the adjustment plate 31; and the first support member 11 is provided with a through hole 111 corresponding to the connecting rod 4, and the connecting rod 4 can be movably passed through the through hole 111 of the first support member 11, so that the first connecting member 21 can be movably matched with the first support member 11; the number of the connecting rods 4 can be two, and the two connecting rods 4 are symmetrically arranged about the central axis of the first connecting member 21. By arranging two connecting rods 4, the first connecting member 21 can move smoothly. Matching Figures 1 to 5 As shown, in the first embodiment of the present invention, the connecting rod 4 may be equipped with a return spring 5, the return spring 5 is sleeved on the connecting rod 4 and the two ends of the return spring 34 are respectively against the adjustment plate 31 and the first support member 11, so that when the adjustment bolt 32 is rotated in the forward direction so that the adjustment plate 31 drives the first connecting member 21 to move closer to the second support plate 12, the return spring 5 is compressed and contracts; and when the adjustment bolt 32 is rotated in the reverse direction, the adjustment bolt 31 reduces the pressure applied to the adjustment plate 31, and the return spring 34 is reset at this time so that the adjustment plate 31 drives the first connecting member 21 to move away from the second support plate 12, thereby resetting the first connecting member 21, so that when disassembling and assembling the expandable slit coil C, the first connecting member 21 can be moved away from the second support plate 12 by rotating the adjustment bolt 32 in the reverse direction. Figure 7 and Figure 8 As shown, in the second embodiment of the present invention, the return spring 5 is matched with the adjusting bolt 32. Specifically, the return spring 5 is sleeved on the connecting rod 4 and the two ends of the return spring 34 are respectively against the adjusting plate 31 and the first support member 11, so that when the adjusting bolt 32 is rotated in the reverse direction, the return spring 5 can also drive the first connecting member 21 to reset.

[0043] Cooperate Figures 3 to 6As shown, when the present invention is in use, first install the expandable slit coil C onto the present invention, such that one end of the core tube C2 of the expandable slit coil C is sleeved on the second connector 22, and the other end of the core tube C2 abuts against the first connector 21, such that the mating conical surface 211 of the first connector 21 is inserted into the core tube C2 and abuts against the core tube C2; then drive the first connector 21 to move by rotating the adjusting bolt 32 of the adjusting assembly 3 to control the frictional force between the first connector 21 and the core tube C2 of the expandable slit coil C, thereby adjusting the rotational damping of the core tube C2 of the expandable slit coil C, such that when people pull the expandable slit sheet C1 of the expandable slit coil C to drive the core tube C2 to rotate, the pulled-out part of the expandable slit sheet C1 is subjected to two-way forces and is stretched and unfolded, and further the pulled-out part of the expandable slit sheet C1 expands.
