DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] See also Figure 1-Figure 9 As shown, a non-woven fabric embossing roller and an embossing process thereof, a non-woven fabric embossing roller, comprising a roller body 1, both sides of the roller body 1 are fixedly connected with a connecting shaft 2; a quick-change mechanism is arranged on the outer side of the roller body 1;

[0035] The quick-change mechanism comprises a middle embossing plate 31, which is arranged on the outside of the roller body 1, and an active cavity 32 is provided at the position of the middle embossing plate 31 near the front and rear ends, and a push block 35 is sleeved inside the active cavity 32, and the bottom end of the push block 35 is inserted into the inside of the connecting groove 37, and the connecting groove 37 is opened on the outside of the roller body 1, and a cover plate assembly is provided at one end of the active cavity 32 away from the connecting groove 37, and a fixing assembly is provided between the push block 35 and the connecting groove 37, and a fixing spring 44 is provided between one end of the push block 35 and the inner wall of the active cavity 32, and side embossing plates 47 are provided at the front and rear ends of the middle embossing plate 31;

[0036] During operation, after the baffle 46 is removed, the push block 35 is pushed to move, so that the fixed block 39 engaged with the fixed groove 38 is disengaged from the inside of the fixed groove 38. At this time, the push block 35 is continued to be pushed to move to the limit to release the connection between the middle embossing plate 31 and the roller body 1. At this time, the middle embossing plate 31 can be pulled away from the roller body 1 to remove the middle embossing plate 31 from the outside of the roller body 1. When the push block 35 moves inside the active cavity 32 and the connecting groove 37, the push block 35 simultaneously squeezes the fixed spring 44, causing the fixed spring 44 to produce elastic deformation. When the push of the push block 35 is stopped, the push block 35 returns to its original position under the action of the restoring force of the fixed spring 44, which is convenient for the next installation of the middle embossing plate 31.

[0037] Furthermore, both sides of the inner wall of the movable cavity 32 are fixedly connected with slide rails 33, and the slide rails 33 are slidably connected inside the slide grooves 34, and the slide grooves 34 are provided at positions on both sides of the push block 35 close to one end of the cover assembly;

[0038] During operation, when the push block 35 is inserted into the connecting groove 37, the combination of the slide rail 33 and the slide groove 34 limits the longitudinal movement of the push block 35, preventing the push block 35 from pushing the baffle 46 out of the active cavity 32. When the push block 35 slides in the active cavity 32, the slide rail 33 also slides in the slide groove 34 synchronously. The combination of the slide rail 33 and the slide groove 34 reduces the friction force of the push block 35 when it moves in the active cavity 32, reduces the contact area between the push block 35 and the inner wall of the active cavity 32, and makes the push block 35 slide more smoothly in the active cavity 32.

[0039] Furthermore, an anti-skid pad 36 is glued to one end of the push block 35 close to the cover assembly, and the anti-skid pad 36 is made of rubber;

[0040] During operation, the anti-skid pad 36 made of rubber material increases the friction force to avoid the anti-skid pad 36 being unable to be pushed due to too little friction force. The anti-skid pad 36 is specifically made of silicone rubber, which can withstand high temperatures and can be used normally in a high temperature environment.

[0041] Furthermore, one end of the fixing spring 44 close to the push block 35 is fixedly connected to the push block 35, and one end of the fixing spring 44 away from the push block 35 is fixedly connected to the inner wall of the movable cavity 32;

[0042] During operation, the restoring force of the fixing spring 44 can achieve the effect of automatically restoring the push block 35 after the thrust force applied to it disappears.

[0043] Furthermore, the cover plate assembly includes a connecting block 45, which is fixedly connected to both sides of the inner wall of the active cavity 32, and the connecting block 45 is made of a nepheline magnet. The connecting block 45 is tightly fitted with one end of a baffle 46, and the baffle 46 is made of cast iron.

[0044] During operation, the surface pattern of the existing non-woven fabric embossing roller is integrally formed during processing and cannot be replaced. When the pattern on the surface of the non-woven fabric needs to be replaced, the embossing roller needs to be completely removed and then replaced with a new one. After the embossing roller is installed, the position of the embossing roller needs to be adjusted so that it can fit the surface of the non-woven fabric, which consumes a lot of time and effort. When the middle embossing plate 31 is to be disassembled, first use a hard card to insert it into the gap between the baffle 46 and the inner wall of the active cavity 32. After the hard card is inserted to the limit, use the card to slightly lift the baffle 46. At this time, pull the lifted corner of the baffle 46 away from the middle embossing plate 31 to release the inner wall of the baffle 46 from the state of being attracted to the connecting block 45, and remove the baffle 46.

[0045] Further, the fixing assembly includes a fixing groove 38, the fixing groove 38 is provided at one end of the push block 35 away from the anti-slip pad 36, the fixing groove 38 is engaged with the fixing block 39, the fixing block 39 is fixedly connected to the end of the push block 39 away from the push block 35 with a movable block 41, the movable block 41 is slidably connected inside the movable groove 42, the movable groove 42 is provided at one end of the connecting groove 37 away from the middle embossed plate 31, and a return spring 43 is provided inside the movable groove 42, the return spring 43 is fixedly connected to the movable block 41 on one side close to the movable block 41, and the return spring 43 is fixedly connected to the inner wall of the movable groove 42 on one side away from the movable block 41;

[0046] When the embossed plate 31 is to be installed, there is no need to remove the baffle 46. It is only necessary to align the push block 35 with the connecting groove 37, and then insert the push block 35 into the interior of the connecting groove 37 so that the fixing block 39 is inserted into the interior of the fixing groove 38. When the fixing block 39 is inserted into the interior of the fixing groove 38, the two sides of the inner wall of the fixing groove 38 squeeze the inclined surface opened at the top of the fixing block 39, so that the fixing block 39 moves under the action of the squeezing force and drives the fixedly connected movable block 41 to move synchronously inside the movable groove 42, so that the movable groove 42 pulls the return spring 43 to produce elastic deformation. When the bottom end of the push block 35 is fully inserted into the interior of the connecting groove 37, the fixing block 39 is also fully inserted into the interior of the fixing groove 38. The squeezing force of the inner wall of the fixing groove 38 on the fixing block 39 disappears, and the fixing block 39 moves and is stuck to the two sides of the inner wall of the fixing groove 38 under the action of the restoring force of the return spring 43, thereby fixing the push block 35 and the roller body 1.

[0047] Furthermore, an insert block 48 is fixedly connected to the inner wall of the side embossed plate 47, and the insert block 48 is sleeved inside the connecting groove 37, and guide grooves 49 are provided on both sides of the insert block 48, and the guide grooves 49 cooperate with guide rails 51, and the guide rails 51 are fixedly connected to both sides of the inner wall of the connecting groove 37, and a notch 52 is provided at one end of the insert block 48 away from the side embossed plate 47;

[0048] During operation, when the side embossing plate 47 is to be installed, the middle embossing plate 31 is first required to be in a state of not being in contact with the outer side of the roller body 1, and then the insert block 48 is inserted into the interior of the connecting groove 37, and the side embossing plate 47 is pushed to move, so that the insert block 48 synchronously slides inside the connecting groove 37, and when the insert block 48 slides inside the connecting groove 37, the guide rail 51 is synchronously inserted into the interior of the guide groove 49, and the longitudinal movement of the side embossing plate 47 is limited by the cooperation of the guide rail 51 and the guide groove 49. When the side embossing plate 47 is pushed to the limit, the middle embossing plate 31 can be installed to limit the lateral movement of the side embossing plate 47, thereby fixing the side embossing plate 47 on the outer side of the roller body 1.

[0049] Further, a non-woven fabric embossing process; the embossing process comprises the following steps:

[0050] S1: Install the rolled nonwoven fabric on a winder and unwind the nonwoven fabric so that the outer side of the nonwoven fabric is closely attached to the outer sides of the middle embossing plate 31 and the side embossing plate 47;

[0051] S2: heating the embossing roller to 80-100°C, starting the winder to drive the non-woven fabric to be wound, and hot pressing the passing non-woven fabric through the middle embossing plate 31 and the side embossing plate 47;

[0052] S3: During the process of rolling up the non-woven fabric, a fan is used to blow the embossed part to dissipate heat, so as to prevent the rolled non-woven fabric from being locally deformed due to heat accumulation.

[0053] Working principle: The surface pattern of the existing non-woven fabric embossing roller is integrally formed during processing and cannot be replaced. When the pattern on the surface of the non-woven fabric needs to be replaced, the embossing roller needs to be completely removed and then replaced with a new one. After the embossing roller is installed, the position of the embossing roller needs to be adjusted so that it can fit the surface of the non-woven fabric, which consumes a lot of time and effort. When the middle embossing plate 31 is to be disassembled, first use a hard card to insert it into the gap between the baffle 46 and the inner wall of the active cavity 32. After the hard card is inserted to the limit, use the card to slightly lift the baffle 46. At this time, pull the lifted corner of the baffle 46 away from the middle embossing plate 31 to release the inner wall of the baffle 46 from the state of being attracted to the connecting block 45, and remove the baffle 46.

[0054] When the baffle 46 is removed, the push block 35 is pushed to move, so that the fixed block 39 engaged with the fixed groove 38 is disengaged from the inside of the fixed groove 38. At this time, the push block 35 is continued to be pushed to move to the limit to release the connection between the middle embossing plate 31 and the roller body 1. At this time, the middle embossing plate 31 can be pulled away from the roller body 1 to remove the middle embossing plate 31 from the outside of the roller body 1. When the push block 35 moves inside the movable cavity 32 and the connecting groove 37, the push block 35 simultaneously squeezes the fixed spring 44, causing the fixed spring 44 to produce elastic deformation. When the push of the push block 35 is stopped, the push block 35 returns to its original position under the action of the restoring force of the fixed spring 44, so as to facilitate the installation of the middle embossing plate 31 next time.

[0055] When the push block 35 is inserted into the connecting groove 37, the combination of the slide rail 33 and the slide groove 34 limits the longitudinal movement of the push block 35, preventing the push block 35 from pushing the baffle 46 out of the active cavity 32. When the push block 35 slides in the active cavity 32, the slide rail 33 also slides in the slide groove 34 synchronously. The combination of the slide rail 33 and the slide groove 34 reduces the friction force of the push block 35 when it moves in the active cavity 32, reduces the contact area between the push block 35 and the inner wall of the active cavity 32, and makes the push block 35 slide more smoothly in the active cavity 32.

[0056] When the centering embossed plate 31 is to be installed, there is no need to remove the baffle 46. It is only necessary to align the push block 35 with the connecting groove 37, and then insert the push block 35 into the interior of the connecting groove 37 so that the fixing block 39 is inserted into the interior of the fixing groove 38. When the fixing block 39 is inserted into the interior of the fixing groove 38, the two sides of the inner wall of the fixing groove 38 squeeze the inclined surface opened at the top of the fixing block 39, so that the fixing block 39 moves under the action of the squeezing force and drives the fixedly connected movable block 41 to move synchronously inside the movable groove 42, so that the movable groove 42 pulls the return spring 43 to produce elastic deformation. When the bottom end of the push block 35 is fully inserted into the interior of the connecting groove 37, the fixing block 39 is also fully inserted into the interior of the fixing groove 38. The squeezing force of the inner wall of the fixing groove 38 on the fixing block 39 disappears, and the fixing block 39 moves and is stuck to the two sides of the inner wall of the fixing groove 38 under the action of the restoring force of the return spring 43, thereby fixing the push block 35 and the roller body 1.

[0057] When the side embossing plate 47 is to be installed, the middle embossing plate 31 must first be in a state where it is not in contact with the outer side of the roller body 1. Then, the insert block 48 is inserted into the interior of the connecting groove 37, and the side embossing plate 47 is pushed to move, so that the insert block 48 synchronously slides inside the connecting groove 37. When the insert block 48 slides inside the connecting groove 37, the guide rail 51 is synchronously inserted into the interior of the guide groove 49. The cooperation of the guide rail 51 and the guide groove 49 has the effect of limiting the longitudinal movement of the side embossing plate 47. When the side embossing plate 47 is pushed to the limit, the middle embossing plate 31 can be installed to limit the lateral movement of the side embossing plate 47, thereby fixing the side embossing plate 47 on the outer side of the roller body 1.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
