Among them, the tensioning shaft 4 for tensioning non-woven fabric is fixedly installed on the sliding component 3. By making the tensioning shaft 4 abut against the non-woven fabric, and then by adjusting the height position of the sliding component 3, the magnitude of the tension force of the non-woven fabric can be adjusted.

[0005] Under normal circumstances, when the tensioning shaft 4 is replaced, it is necessary to remove the sliding component 3 and the tensioning shaft as a whole from the support frame 2 before the tensioning shaft 4 can be disassembled from the sliding component 3, resulting in a cumbersome replacement of the tensioning shaft 4.

[0006] Therefore, how to design a structure that facilitates the disassembly and assembly of the tensioning shaft has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0007] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide a tensioning shaft for non-woven fabric production to solve the problem that the replacement of the tensioning shaft is relatively troublesome.

[0008] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] A tensioning shaft for non-woven fabric production includes two vertically arranged support frames and a sliding component that is slidably connected along the vertical direction of the support frames. The tensioning shaft is horizontally arranged and installed on the sliding components on both sides. The sliding component includes a sliding seat. An upwardly open placing groove is provided on the side wall of the sliding seat. The end of the tensioning shaft is placed in the placing groove. It also includes a plugging seat.

Detailed Embodiments

[0030] The technical solutions in the embodiments of the present utility model will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0031] This embodiment provides a tensioning shaft for non-woven fabric production, which is mainly used for replacing the tensioning shaft and shortening the replacement time of the tensioning shaft.

[0032] As Figure 2 shown, it includes a processing table 1 and two groups of support frames 2 vertically installed on the top wall of the processing table 1. Among them, a moving groove 21 is provided on the support frame 2 along the vertical direction, and a sliding component 3 is slidably connected in the moving groove 21. A horizontally placed tensioning shaft 4 is fixedly provided on the sliding component 3. Among them, the peripheral wall of the tensioning shaft 4 is used to abut against the non-woven fabric, so as to tension the non-woven fabric. Specifically, it further includes a driving mechanism 5 for driving the sliding component 3 to slide along the vertical direction.

[0033] Through the driving mechanism 5, the sliding component 3 can be driven to move up and down, and then the height of the tensioning shaft 4 can be changed. Since the peripheral wall of the tensioning shaft 4 abuts against the non-woven fabric, the tension of the non-woven fabric can be adjusted through the tensioning shaft 4.

[0034] In order to realize the horizontal setting of the tensioning shaft 4, in this embodiment, as Figure 2 and Figure 3 shown, sliding components 3 are provided in the moving grooves 21 of the two support frames 2, and the two sliding components 3 are on the same horizontal plane.

[0035] Specifically, in order to realize the installation of the driving mechanism 5, in this embodiment, as Figure 2 and Figure 3 shown, the driving mechanism 5 includes an electric push rod 51, a connecting plate 52 and two driving rods 53. Among them, the driving rods 53 are respectively fixedly connected to the sliding components 3 on the same side. The electric push rod 51 is fixedly installed on the bottom wall of the processing table 1, the telescopic end of the electric push rod 51 is fixedly connected to the connecting plate 52, and the driving rod 53 is fixedly connected to the driving rods 53 on both sides.

[0036] It should be noted here that the connecting plate 52 is horizontally placed.

[0037] By using the electric push rod 51 to drive the connecting plate 52 to rise and fall, the sliding components 3 on both sides can be driven to rise and fall synchronously through the driving rods 53, and then the position of the tensioning shaft 4 can be adjusted.

[0038] In order to improve the stability of the sliding component 3 sliding along the vertical direction, in this embodiment, asFigure 2 , Figure 4 and Figure 6 As shown in Figure 2 , Figure 4 and Figure 6 , a guiding groove 211 is provided on the side wall of the moving groove 21, and a guiding block 3131 extending into the guiding groove 211 is provided on the sliding assembly 3. Among them, the outer wall of the guiding block 3131 is slidably connected to the inner wall of the guiding groove 211, thereby improving the stability of the up and down sliding of the sliding assembly 3.

[0039] For the convenience of installing the tensioning shaft 4, in this embodiment, as Figure 4 and Figure 5 shown, the sliding assembly 3 includes a sliding seat 31 and a sealing seat 32. An upward-opening placement groove 3121 is provided on the side wall of the sliding seat 31 for placing the end of the tensioning shaft 4. The sliding seat 31 is fixedly connected to the sealing seat 32 by bolts and the tensioning shaft 4 is sealed in the placement groove 3121, thereby realizing the installation of the tensioning shaft 4.

[0040] It should be noted here that the driving rod 53 is fixedly connected to the sliding seat 31.

[0041] Specifically, as Figure 4 , Figure 5 and Figure 6 shown, the sliding seat 31 includes a bottom plate 311 placed horizontally. A first countersunk hole 3111 is provided on the bottom plate 311. A second threaded hole 531 is provided at the top of the driving rod 53. The bottom plate 311 is fixedly connected to the driving rod 53 by a first positioning bolt 54. Among them, the end of the first positioning bolt 54 sinks into the first countersunk hole 3111, and the first positioning bolt 54 is threadedly connected to the second threaded hole 531.

[0042] As Figure 6 shown, a first side plate 312 extending vertically upward is fixedly provided on the top wall of the bottom plate 311. The placement groove 3121 is provided on the first side plate 312, and the longitudinal section of the placement groove 3121 is U-shaped with an upward opening. When the tensioning shaft 4 is installed, the peripheral wall of the tensioning shaft 4 abuts against the inner wall of the placement groove 3121.

[0043] As Figure 6 shown, two groups of opposite and even second side plates 313 are further fixedly provided on the top wall of the bottom plate 311. The guiding block 3131 is fixedly installed on the second side plate 313. When the tensioning shaft 4 is installed in the placement groove 3121, the tensioning shaft 4 is located between the two second side plates 313.

[0044] When the tensioning shaft 4 is installed inside the placement groove 3121, in order to limit the upward movement of the tensioning shaft 4, in this embodiment, the blocking seat 32 includes a blocking top plate 322 installed above the first side plate 312 and the second side plate 313, wherein the blocking top plate 322 seals the opening at the top of the placement groove 3121, thereby limiting the movement of the tensioning shaft 4.

[0045] Since the tensioning shaft 4 is installed in the placement groove 3121, in order to limit the movement of the tensioning shaft 4 along its own axial direction, in this embodiment, Figure 5 , Figure 7 and Figure 8 As shown, the blocking seat 32 also includes a blocking side plate 321, the end wall of the tensioning shaft 4 is provided with a plug hole 41, and a supporting column 3211 is fixedly provided on the blocking side plate 321. When the tensioning shaft 4 is installed, Figure 4 As shown, the supporting column 3211 is inserted into the inserting hole 41, and the end wall of the supporting column 3211 abuts against the inner wall of the inserting hole 41, thereby limiting the axial movement of the tensioning shaft 4.

[0046] In order to fix the blocking seat 32, in this embodiment, as shown in FIG. Figure 5 , Figure 6 and Figure 7 As shown, the blocking side plate 321 is provided with a second countersunk hole 3212, and the second side plate 313 is provided with a first threaded hole 3133. When the blocking seat 32 is installed, the first threaded hole 3133 is aligned with the second countersunk hole 3212, and the blocking side plate 321 abuts against the side wall of the second side plate 313. It also includes a second positioning bolt 6, wherein the second positioning bolt 6 passes through the second countersunk hole 3212, and the second positioning bolt 6 is threadedly connected to the first threaded hole 3133, thereby realizing the fixation of the blocking seat 32.

[0047] When the tensioning shaft 4 is installed inside the placement groove 3121, in order to realize the installation of the blocking seat 32, in this embodiment, the blocking seat 32 moves toward the side of the tensioning shaft 4 along the axial direction of the tensioning shaft 4, so that the supporting column 3211 is aligned with the plug-in hole 41. When the blocking side plate 321 of the blocking seat 32 abuts against the second side plate 313, the supporting column 3211 is plugged into the plug-in hole 41, thereby realizing the installation of the blocking seat 32 and the positioning of the tensioning shaft 4.

[0048] In order to enable the supporting column 3211 to be smoothly inserted into the insertion hole 41, Figure 8 As shown, the end wall of the plug-in hole 41 is also provided with a guide bevel 411, wherein the guide bevel 411 is a conical surface. When the blocking side plate 321 moves toward the side of the tensioning shaft 4, the end of the supporting column 3211 can first abut against the guide bevel 411, and then be plugged into the plug-in hole 41 along the guide bevel 411, thereby realizing the smooth installation of the supporting column 3211.

[0049] As Figure 4 shown, when the supporting column 3211 is inserted into the insertion hole 41, at this time, the outer wall of the supporting column 3211 is rotatably connected to the inner wall of the insertion hole 41. The supporting column 3211 lifts the tensioning shaft 4 upward, so that the tensioning shaft 4 is disengaged from abutting against the bottom wall of the placement groove 3121. When the tensioning shaft 4 tensions the non-woven fabric, with the rotation of the tensioning shaft 4, the wear of the inner wall of the placement groove 3121 can be reduced.

[0050] In order to achieve the stable installation of the plugging seat 32, in this embodiment, as Figure 6 shown, the top wall of the second side plate 313 is provided with an insertion groove 3132 arranged along the axial direction of the tensioning shaft 4. As Figure 7 shown, the top wall of the plugging top plate 322 is provided with an insertion rib 3221. When the plugging seat 32 is installed, the insertion rib 3221 is inserted into the insertion groove 3132, and the insertion rib 3221 is slidably connected to the insertion groove 3132, thereby ensuring the stable movement of the plugging seat 32.

[0051] Through the above settings, when it is necessary to remove the tensioning shaft 4 from the sliding component 3, at this time, the second positioning bolt 6 is removed from the second side plate 313 to release the fixation of the plugging seat 32 and the sliding seat 31. At this time, the plugging seat 32 is moved along the axial direction of the tensioning shaft 4 to the side away from the tensioning shaft 4, the supporting column 3211 is pulled out from the insertion hole 41, and the plugging top plate 322 releases the plugging of the top of the placement groove 3121. At this time, the tensioning shaft 4 can be taken out from the placement groove 3121. Compared with the traditional method of first removing the tensioning shaft 4 and the sliding component 3 from the support frame 2 and then removing the tensioning shaft 4 from the sliding component 3, the disassembly and assembly steps of the tensioning shaft 4 are simplified, which is convenient for the disassembly and assembly of the tensioning shaft 4.

[0052] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
