Description

Technical Field

[0001] The utility model relates to the technical field of material roller fixing, in particular to a material roller fixing mechanism for producing single S non-woven fabrics. Background Art

[0002] Single S non-woven fabric is a single-layer fiber mesh non-woven fabric. Compared with SS non-woven fabric, SMS non-woven fabric and SMMS non-woven fabric, single S non-woven fabric has the smallest sheet thickness, fewer single sheet gaps and smaller gap depth. Therefore, after rolling, single S non-woven fabric of the same diameter is denser than SS non-woven fabric, SMS non-woven fabric and SMMS non-woven fabric, heavier and more difficult to carry.

[0003] After production, single S non-woven fabric is rolled into a material roll through a material shaft for transportation and storage. The material shaft is fixed in position on the frame by a fixing mechanism. Both ends of the material shaft have bearing sleeves and can rotate independently of the material roller fixing mechanism. Therefore, the material roller fixing mechanism only needs to be clamped and fixed.

[0004] The original single S non-woven fabric production roller fixing mechanism is as shown in the attached figure of the specification. Figure 9 As shown, the limit is clamped by a block and a limit hook, and the limit hook is clamped by a pneumatic push rod or an electric push rod. However, in actual production and processing, there is no obvious advantage in driving the limit hook by a pneumatic push rod or an electric push rod. Instead, there are some inconveniences. Specifically, the crane suspends the fixed material shaft through the lifting belt, and then the controller of the production line controls the pneumatic push rod or the electric push rod to extend and drive the limit hook to flip downward and separate from the material shaft, and finally hoist and transport it by the crane. Obviously, the controller of the production line will not be set at the position corresponding to the winding mechanism at the end of the production line. Therefore, at least two staff members are required to divide the work or one staff member is required to go back and forth between the winding mechanism and the controller, resulting in waste of personnel or inconvenience in operation, which is insufficient.

[0005] In response to the shortcomings of the existing technology, the utility model provides a single S non-woven fabric production material roller fixing mechanism, which is used to solve the problems of labor waste and inconvenience in operation during the actual operation of the existing single S non-woven fabric production material roller fixing mechanism, in which the limiting hook is clamped by a pneumatic push rod or an electric push rod.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

The back side of the handwheel disc is respectively fixedly connected to repulsive magnetic blocks and attractive magnetic blocks with the same and opposite magnetic poles as the opposite ends of the passive magnetic block. A positioning component for angular positioning of the handwheel disc is also provided between the handwheel disc and the limit hook.

[0011] Preferably, smooth strips are provided on the top of the inner wall of the slide groove, the bottom of the inner wall and both sides of the inner wall, and the stop pin and the passive magnetic block are slidably connected to the smooth strips.

[0031] like Figures 1-8 As shown, the utility model provides a technical solution: a single S non-woven fabric production material roller fixing mechanism, comprising a fixed stopper 3 and an L-shaped limit hook 4 arranged on a frame 1 and clamped on both sides of the material shaft 2, the limit hook 4 is rotatably connected to a pin shaft 5 arranged on the frame 1, and a movable stopper 6 is fixedly connected to the limit hook 4 corresponding to one side of the fixed stopper 3, and the opposite surfaces of the fixed stopper 3 and the movable stopper 6 are both provided with a limit groove 7 adapted to the shape of the material shaft 2, and the opposite surfaces of the fixed stopper 3 and the movable stopper 6 are both provided with a guide inclined surface 8 at a position above the limit groove 7, a positioning column 9 fixedly connected to the frame 1 is provided below the end of the limit hook 4 away from the movable stopper 6, and a tension spring 11 is installed between the positioning column 9 and a through hole 10 provided at the end of the limit hook 4 away from the movable stopper 6;

[0032] The frame 1 is provided with a slide groove 12 on the back of the vertical limit hook 4 at a position between the through hole 10 and the pin shaft 5. A stop pin 13 is slidably connected in the slide groove 12 to block the upper part of the limit hook 4. A passive magnetic block 14 is fixedly installed on the upper surface of the stop pin 13. Fluid strips 20 are provided on the top, bottom and both sides of the inner wall of the slide groove 12. The stop pin 13 and the passive magnetic block 14 are both slidably connected to the fluid strip 20.

[0033] A fixed shaft 15 is fixedly connected to the position between the through hole 10 and the pin shaft 5 on the limiting hook 4. A handwheel disc 16 is rotatably connected to the surface of the fixed shaft 15. A repulsive magnet 17 and an attractive magnet 18 with the same and opposite magnetic poles as the opposite end of the passive magnet 14 are respectively fixedly connected to the back of the handwheel disc 16. The two magnetic poles of the passive magnet 14, the repulsive magnet 17, and the attractive magnet 18 are respectively located on the front and the back. The repulsive magnet 17 and the attractive magnet 18 have the same shape and structure, and the positive and negative magnetic pole directions are opposite. There are two attractive magnets 18 and two repulsive magnets 17. The two attractive magnets 18 and the two repulsive magnets 17 are symmetrically arranged on the back of the handwheel disc 16 respectively, and the two attractive magnets 18 and the two repulsive magnets 17 are distributed in an annular array on the back of the handwheel disc 16. Symbol marks 21 are respectively arranged at the positions corresponding to the attractive magnet 18 and the repulsive magnet 17 on the front of the handwheel disc 16;

[0034] A positioning assembly 19 for positioning the angle of the handwheel disc 16 is further arranged between the handwheel disc 16 and the limiting hook 4. The positioning assembly 19 includes a positioning chuck 191 sleeved on the fixed shaft 15 and fixedly connected to the front of the limiting hook 4. An active chuck 192 is fixedly connected to the back of the handwheel disc 16 and is movably sleeved on the surface of the fixed shaft 15. The positioning chuck 191 is movably clamped with a convex rib 194 arranged on the back of the active chuck 192 through a clamping groove 193 arranged on the front. A compression spring 195 installed on the fixed shaft 15 is further arranged on the front of the handwheel disc 16. The clamping groove 193 and the convex rib 194 are both strip-shaped and are distributed in an annular array around the fixed shaft 15. A cap 196 sleeved on the surface of the compression spring 195 is fixedly connected to the front end of the fixed shaft 15.

[0035] Working principle:

[0036] The angle of the handwheel disc 16 is positioned through the positioning assembly 19. Specifically, when the handwheel disc 16 is rotated to drive the active chuck 192 to rotate together, when the convex rib 194 rotates from the current clamping groove 193 to the adjacent clamping groove 193, that is, rotates 90°, it switches between the position where the attractive magnet 18 corresponds to the passive magnet 14 and the position where the repulsive magnet 17 corresponds to the passive magnet 14; when the handwheel disc 16 is rotated so that the repulsive magnet 17 is aligned with the passive magnet 14, the stop pin 13 is pushed by the magnetic force to be separated from the limiting hook 4. At this time, the material shaft 2 can be directly lifted upward to smoothly squeeze the limiting hook 4 to rotate counterclockwise and displace, so as to remove the material shaft 2. When installing the material shaft 2, the fixed stop block 3 and the movable stop block 6 are directly pressed downward, and the limiting hook 4 is squeezed by the material shaft 2 to rotate counterclockwise and displace, then the installation of the material shaft 2 is completed. When the handwheel disc 16 is rotated so that the attractive magnet 18 is aligned with the passive magnet 14, the stop pin 13 is attracted by the magnetic force to extend and move above the limiting hook 4, preventing the limiting hook 4 from rotating counterclockwise to lock the material shaft 2, and the operation is convenient and simple.
