DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The present embodiment provides an oil-absorbing and wear-resistant industrial wiping paper preparation device, which is mainly used for cutting wiping paper to solve the problem of burrs on the wiping paper after cutting.

[0033] like Figure 2 As shown, it includes a first hot pressing roller group 2 and a second hot pressing roller group 3 and a driving mechanism 4 that drives the first hot pressing roller group 2 and the second hot pressing roller group 3 to rotate synchronously in opposite directions, wherein the wiping paper 1 passes through the middle of the first hot pressing roller group 2 and the second hot pressing roller group 3, and the second hot pressing roller group 3 is equipped with a hot pressing cutting component 5 for cutting and trimming the wiping paper 1, as shown in FIG. Figure 1 As shown, a hot pressed edge 10 is formed on the cut edge of the wiping paper 1 to prevent fiber burrs from appearing on the edge of the wiping paper 1 after cutting.

[0034] In order to facilitate the tearing of the wiping paper 1, in this embodiment, Figure 1 As shown, the hot pressing cutting component 5 can also form a tearing auxiliary line 11 on the cut wiping paper 1, wherein the tearing auxiliary line 11 is arranged along the width of the cut wiping paper 1, and the tearing auxiliary line 11 is perpendicular to the cutting edge of the wiping paper 1, and a cutting hole is formed on the tearing auxiliary line 11, and the wiping paper 1 is torn off from the cutting hole.

[0035] At the same time, Figure 1As shown, a hot-pressed edge 10 is also formed at the position of the tearing auxiliary line 11, and the cutting hole is located on the hot-pressed edge 10. It can be seen from the single piece of wiping paper 1 after being torn that hot-pressed edges 10 are formed all around the wiping paper 1 to prevent fibers in the wiping paper 1 from falling off.

[0036] In order to cut the whole piece of wiping paper 1 into a suitable width, in this embodiment, Figure 2 As shown, the second hot pressing roller group 3 is provided with a plurality of hot pressing and cutting components 5 arranged axially along the second hot pressing roller group 3 , and two adjacent hot pressing and cutting components 5 are plugged into each other, and a circular cutting knife 55 for cutting the wiping paper 1 is installed between two adjacent hot pressing and cutting components 5 .

[0037] Through the above-mentioned arrangement, when the first hot pressing roller group 2 and the second hot pressing roller group 3 rotate synchronously in opposite directions under the action of the driving mechanism 4, the wiping paper 1 passes through the gap between the first hot pressing roller group 2 and the second hot pressing roller group 3 and moves forward steadily. At this time, the second hot pressing roller group 3 drives the hot pressing cutting assembly 5 and the circular cutting knife 55 to rotate synchronously, cuts the entire piece of wiping paper 1, cuts the wiping paper 1 into strips and performs hot pressing treatment on the cut edges of the wiping paper 1.

[0038] In order to form a hot pressed edge 10 at the cut edge of the wiping paper 1, in this embodiment, as shown in FIG. Figure 6 , Figure 8 and Fig. 9 As shown, the hot pressing and cutting assembly 5 includes a sleeve 51, and both side end walls of the sleeve 51 are provided with hot pressing flanges 52 extending radially outward from the sleeve 51. During installation, the hot pressing flanges 52 abut against the side walls of the first hot pressing roller group 2, and the wiping paper 1 is squeezed between the peripheral walls of the hot pressing flanges 52 and the peripheral walls of the first hot pressing roller group 2. The hot pressing flanges 52 are used to form a hot pressing edge 10 on the wiping paper 1 to prevent fibers from falling off at the cutting position of the wiping paper 1.

[0039] It is worth explaining here that since the circular cutter 55 is installed between two adjacent groups of hot pressing and cutting components 5, there are hot pressing flanges 52 on both sides of the circular cutter 55. The wiping paper 1 at the hot pressing flange 52 forms a hot pressing edge 10. When the circular cutter 55 cuts the wiping paper 1, the circular cutter 55 forms a cutting line on the hot pressing edge 10, which solves the problem of fiber falling off at the cutting position.

[0040] In order to realize the installation of the circular cutting knife 55, in this embodiment, as Figure 8 and Fig.10As shown, one side end wall of the sleeve 51 is provided with a positioning ring 54 arranged along the axial direction of the sleeve 51, wherein the outer diameter of the positioning ring 54 is smaller than the outer diameter of the hot pressing flange 52, and a plurality of circumferentially distributed positioning teeth 541 are provided on the peripheral wall of the positioning ring 54, wherein a positioning groove 551 for inserting the positioning teeth 541 is provided on the inner side of the ring cutting knife 55. When the ring cutting knife 55 is installed, the ring cutting knife 55 is inserted toward one side of the positioning ring 54 along the axial direction of the sleeve 51, so that the positioning teeth 541 are inserted into the positioning groove 551, and the side wall of the positioning tooth 541 abuts against the side wall of the positioning groove 551 to limit the rotation of the ring cutting knife 55.

[0041] It is worth noting that after the circular cutter 55 is installed on the positioning ring 54 , the outer diameter of the outer blade of the circular cutter 55 is larger than the outer diameter of the hot pressing flange 52 , so that the hot pressing edge 10 can be cut.

[0042] The other end wall of the hot pressing flange 52 of the sleeve 51 is provided with a plug-in ring groove 521 for inserting the positioning ring 54. After the ring cutter 55 is installed on the positioning ring 54, the positioning ring 54 is plugged into the plug-in ring groove 521 of another hot pressing and cutting component 5. At this time, the ring cutter 55 can be clamped between the sleeves 51 of the two adjacent hot pressing and cutting components 5 to achieve the positioning of the ring cutter 55.

[0043] The wiping paper 1 is usually in the form of an independent sheet when in use. To facilitate tearing of the strip-shaped wiping paper 1 cut by the circular cutting knife 55 , a tearing auxiliary line 11 needs to be formed on the wiping paper 1 .

[0044] In order to realize the formation of the tearing auxiliary line 11, in this embodiment, as Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, a hot pressing rib 53 is provided on the peripheral wall of the sleeve 51 along the axial direction of the sleeve 51, wherein the hot pressing rib 53 is connected with the hot pressing flanges 52 on the two end walls of the sleeve 51 and are perpendicular to each other, the outer diameter of the hot pressing rib 53 is consistent with the outer diameter of the hot pressing flange 52, and the hot pressing rib 53 is also provided with a plurality of cutting teeth 531 distributed along the axial direction of the sleeve 51.

[0045] After the wiping paper 1 is placed between the first hot pressing roller group 2 and the second hot pressing roller group 3, the second hot pressing roller group 3 drives the sleeve 51 to rotate one circle. At this time, the hot pressing rib 53 and the wiping paper 1 complete a cutting action. The hot pressing rib 53 forms a hot pressing edge 10 on the wiping paper 1, and then the cutting teeth 531 are used to cut a cutting hole on the hot pressing edge 10, so that the formation of the tearing auxiliary line 11 can be achieved.

[0046] It is worth noting that the end wall of the cutting tooth 531 on the hot pressing flange 52 is flush with the end wall of the hot pressing flange 52, and the end wall of the cutting tooth 531 abuts against the end wall of the circular cutting knife 55, and the cutting tooth 531 can punch out a cutting hole at the cutting line position of the circular cutting knife 55, such as Figure 1 As shown in the right figure in FIG. 1 , the cutting hole at the end is located on the cutting line, making it easier to tear off the wiping paper 1.

[0047] Since the peripheral wall of the first hot pressing roller group 2 is in contact with the peripheral wall of the hot pressing flange 52 in the second hot pressing roller group 3, and the outer diameter of the circular cutting knife 55 is larger than the outer diameter of the hot pressing flange 52, the cutting teeth 531 are installed on the hot pressing rib 53. At this time, when the wiping paper 1 is subjected to hot pressing treatment, in order to avoid the circular cutting knife 55 and the cutting teeth 531 directly touching the peripheral wall of the second hot pressing roller group 3, causing damage to the circular cutting knife 55 and the cutting teeth 531.

[0048] Therefore, in this embodiment, if Figure 4 , Figure 6 and Figure 7 As shown, the first hot pressing roller group 2 includes a rotating shaft 21 and a first roller 22, wherein the rotating shaft 21 is fixedly mounted on the end wall of the first roller 22, the axis of the rotating shaft 21 coincides with the axis of the first roller 22, and the peripheral wall of the first roller 22 is provided with a plurality of cutting grooves 221 arranged along the axis of the first roller 22, specifically, the number of the cutting grooves 221 matches the number of the circular cutting knives 55; after the first hot pressing roller group 2 and the second hot pressing roller group 3 are installed, the blade of the circular cutting knife 55 is inserted into the cutting groove 221, and a plurality of shearing grooves 222 are further arranged on the peripheral wall of the first roller 22, wherein the plurality of shearing grooves 222 are distributed along the axial direction of the first roller 22, as shown in FIG. Figure 6 As shown, the shearing groove 222 is used for inserting the cutting teeth 531 , and at this time, the peripheral wall of the hot pressing flange 52 abuts against the peripheral wall of the first roller shaft 22 .

[0049] In order to fix the sleeve 51 in the hot pressing and cutting assembly 5, in this embodiment, as shown in FIG. Figure 5 , Figure 6 and Fig.11 As shown, the second hot pressing roller group 3 includes a rotating tube 31 and a second roller shaft 32. The rotating tube 31 is fixedly installed on the end wall of the second roller shaft 32. A positioning hole 324 is provided on the peripheral wall of the second roller shaft 32, and a bolt hole 511 is provided on the sleeve 51. It also includes a positioning bolt 6. When the hot pressing and cutting assembly 5 is installed, the sleeve 51 is sleeved on the outside of the second roller shaft 32, and then the bolt hole 511 on the sleeve 51 is aligned with the positioning hole 324 on the second roller shaft 32, and then the positioning bolt 6 is passed through the bolt hole 511 and extended into the positioning hole 324, so that the positioning bolt 6 is threadedly connected with the positioning hole 324, thereby fixing the sleeve 51.

[0050] It is worth noting that the positioning hole 324 is a blind hole.

[0051] In the above solution, after the sleeve 51 is inserted into the second roller shaft 32, in order to accurately align the positioning hole 324 with the bolt hole 511, the sleeve 51 usually needs to be rotated, resulting in low installation accuracy of the sleeve 51 and a long installation time of the sleeve 51. Therefore, in this embodiment, Figure 5 , Fig. 9 and Fig.11 As shown, a plurality of limiting ribs 321 distributed along the circumference of the second roller shaft 32 are provided on the circumferential wall of the second roller shaft 32, and the limiting ribs 321 are arranged along the axial direction of the second roller shaft 32. The inner wall of the sleeve 51 is provided with an insertion groove 513 arranged along the axial direction of the sleeve 51. When the sleeve 51 is installed, the limiting ribs 321 are inserted into the insertion groove 513 of the sleeve 51, and the side walls of the limiting ribs 321 abut against the side walls of the insertion groove 513 to limit the rotation of the sleeve 51. Specifically, there are three limiting ribs 321 and three insertion grooves 513, and the three limiting ribs 321 are distributed at 180° on the second roller shaft 32. When the sleeve 51 is sleeved on the second roller shaft 32, as the sleeve 51 is pushed, the positioning hole 324 and the bolt hole 511 can be aligned without rotating the sleeve 51, thereby realizing the quick installation of the sleeve 51.

[0052] In order to heat press the wiping paper 1, it is necessary to keep the heat pressing flange 52 and the heat pressing rib 53 at a relatively high temperature. Figure 5 , Figure 6 and Figure 7 As shown, the second roller shaft 32 is provided with a roller shaft inner cavity 320 connected with the rotating tube 31, wherein the peripheral wall of the second roller shaft 32 is provided with an air guide groove 322 arranged along the axial direction of the second roller shaft 32, and the second roller shaft 32 is provided with a plurality of air holes 323 connecting the air guide groove 322 with the roller shaft inner cavity 320; when the sleeve 51 is installed on the second roller shaft 32, the hot pressing retaining edge 53 is aligned with the air guide groove 322.

[0053] Through the above arrangement, hot air is transported to the inner cavity 320 of the roller shaft through the rotating tube 31. At this time, the hot air enters the air guide groove 322 through the air holes, and then the hot pressing edge 53 can be heated, thereby increasing the temperature of the hot pressing edge 53 and improving the hot pressing effect of the hot pressing edge 10 in the wiping paper 1 cut into strips.

[0054] When the whole piece of wiping paper 1 is cut by the circular cutting knife 55, the wiping paper 1 at the cutting line position needs to be heat-pressed by the heat-pressing flange 52. In order to heat the heat-pressing flange 52, in this embodiment, Figure 8 and Fig. 9As shown, the inner wall of the sleeve 51 is provided with an annular groove 514, wherein two groups of annular grooves 514 are provided and are respectively close to one side of the hot pressing flange 52, and the annular grooves 514 are connected with the air guide grooves 322, and the air guide grooves 322 are used to transport hot air into the annular grooves 514, thereby improving the heating effect on the hot pressing flange 52.

[0055] When the number of sleeves 51 and the circular cutting blades 55 installed on the second hot pressing roller group 3 is changed, taking the reduction of the number of sleeves 51 as an example, the sleeves 51 cannot completely cover the air guide groove 322. At this time, the hot air in the air guide groove 322 is easily dissipated from the end of the air guide groove 322, causing energy waste and reducing the rate of temperature increase of the sleeve 51. Therefore, in this embodiment, Fig. 9 As shown, the end wall of the sleeve 51 is also fixedly provided with an air baffle plate 512. When the sleeve 51 is installed on the second roller shaft 32, the air baffle plate 512 is inserted into the air guide groove 322 to prevent the hot air in the air guide groove 322 at the position of the sleeve 51 from dissipating outward. At the same time, it is necessary to block the air holes 323 at the position where the sleeve 51 is not installed to improve the utilization efficiency of heat.

[0056] In order to realize synchronous reverse rotation of the first hot pressing roller group 2 and the second hot pressing roller group 3, in this embodiment, as shown in FIG. Figure 3 As shown, the driving mechanism 4 includes a motor 41, a pulley set 42, a first gear 43 and a second gear 44, wherein the output shaft of the motor 41 is connected to one of the pulleys of the pulley set 42, the other pulley of the pulley set 42 is connected to the rotating shaft 21, the first gear 43 is fixedly mounted on the rotating shaft 21, and the second gear 44 is fixedly mounted on the rotating tube 31, wherein the first gear 43 and the second gear 44 are meshed with each other, and the first gear 43 and the second gear 44 are completely consistent.

[0057] The first gear 43 and the second gear 44 are connected to the rotating shaft 21 or the rotating tube 31 through a key. During the installation process, the ring cutter 55 needs to be inserted into the cutting groove 221, and the cutting tooth 531 needs to be inserted into the shearing groove 222. The end walls of the first gear 43 and the second gear 44 are both provided with a triangular timing mark 45, such as Figure 3 As shown, at this time, the timing marks 45 on the first gear 43 and the second gear 44 are aligned with each other.

[0058] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
