Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, and more specifically to a napping roller structure for imitation wool napping. Background Technology

[0002] Pile-up, also known as napping, is a process in which some of the fibers in a fabric are pulled out and formed into a layer of nap on the fabric surface. The purpose of pile-up is to improve the style and appearance of the fabric, giving it a wool-like feel, increasing its fluffiness, making the fabric thicker, softer to the touch, and enhancing its warmth.

[0003] Existing synthetic fiber materials need to be napped to make their surface resemble cashmere. The existing napping method is to use napping rollers to create a napping, brushing, or brushing effect on the surface of the fabric to make it resemble cashmere.

[0004] However, in existing napping rollers, a metal sleeve is usually fixed directly on the outer wall of the roller body, and multiple needle bars are fixed in the metal sleeve. The outer end of the needle bar extends out of the metal sleeve. However, during use, the needle bar is prone to being damaged due to being too close to or pressed against the guide roller, or it may cause hard collisions with other surrounding parts during handling and installation. This can easily cause the needle bar to bend or damage the object it collides with, and it can also easily damage the outer surface of the guide roller, affecting normal use. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flocking roller structure for imitation wool flocking. When its needle bar is subjected to strong pressure, it can partially retract into the polytetrafluoroethylene sleeve body, reducing the probability of its tip deformation or breakage, and also reducing damage to the outer surface of the surrounding guide roller or the objects in contact with it.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A flocking roller structure for imitation wool flocking includes a main roller body, wherein a middle support shaft portion extending outward horizontally is formed in the middle of both the left and right end faces of the main roller body.

[0008] Multiple axially extending slots are formed on the outer side wall of the main roller body. All slots are evenly distributed on the outer side wall of the main roller body with the central axis of the main roller body as the center. A polytetrafluoroethylene sleeve is fitted on the outer side wall of the main roller body. Multiple inner mounting holes are formed on the inner side wall of the polytetrafluoroethylene sleeve. An insertion through hole extending outward from the outer side wall of the polytetrafluoroethylene sleeve is formed in the middle of the outer end face of the inner mounting hole. The insertion through hole corresponds to the corresponding slot. The connecting post is inserted into the corresponding inner mounting hole and the corresponding slot. A needle rod is fixed or formed on the outer end of the connecting post. The needle rod is inserted into the corresponding insertion through hole, and the needle tip at its outer end extends out of the outer side wall of the polytetrafluoroethylene sleeve.

[0009] A tension spring is inserted into the inner mounting hole. One end of the tension spring is fixed to the outer end face of the connecting post, and the other end of the tension spring is fixed to the outer end face of the inner mounting hole.

[0010] A metal sleeve is fixed to the outer side of the polytetrafluoroethylene sleeve. The metal sleeve has an external through hole that is aligned with and communicates with the corresponding insertion through hole. The needle bar is inserted into the corresponding external through hole, and the inner sidewall of the external through hole and the inner sidewall of the insertion through hole are in close contact with the outer sidewall of the needle bar.

[0011] The left and right ends of the main roller are fixedly connected to end plates by multiple bolts, and the left and right ends of the polytetrafluoroethylene sleeve and the metal sleeve are pressed against the inner end surfaces of the corresponding end plates.

[0012] The outstanding effect of this utility model is:

[0013] When subjected to strong pressure, its needle bar can partially retract into the polytetrafluoroethylene sleeve to prevent its tip from deforming or breaking, and also reduce damage to the outer surface of the surrounding guide rollers or objects that collide with it.

[0014] Moreover, its main roller body and PTFE sleeve body are easy to install and disassemble. It is only necessary to remove the corresponding end plate to separate the two for maintenance and repair. Attached Figure Description

[0016] Figure 2 This is a partial sectional view of the present invention;

[0017] Figure 3 yes Figure 2 A magnified view of a portion of the image. Detailed implementation method:

[0018] For example, see below. Figures 1 to 3As shown, a flocking roller structure for imitation wool flocking includes a main roller body 10, wherein a middle support shaft portion 11 extending outward horizontally is formed in the middle of both the left and right end faces of the main roller body 10.

[0019] The outer side wall of the main roller body 10 is formed with a plurality of axially extending slots 12. All slots 12 are evenly distributed on the outer side wall of the main roller body 10 with the central axis of the main roller body 10 as the center. A polytetrafluoroethylene sleeve 20 is sleeved on the outer side wall of the main roller body 10. A plurality of inner mounting holes 21 are formed on the inner side wall of the polytetrafluoroethylene sleeve 20. An insertion through hole 22 extending outward from the outer side wall of the polytetrafluoroethylene sleeve 20 is formed in the middle of the outer end face of the inner mounting hole 21. The inner mounting hole 21 corresponds to the corresponding slot 12. The connecting post 30 is inserted into the corresponding inner mounting hole 21 and the corresponding slot 12. The outer end of the connecting post 30 is fixed or formed with a needle rod 31. The needle rod 31 is a metal rod. The needle rod 31 is inserted into the corresponding insertion through hole 22. The needle tip of its outer end extends out of the outer side wall of the polytetrafluoroethylene sleeve 20.

[0020] A tension spring 1 is inserted into the inner mounting hole 21. One end of the tension spring 1 is fixed to the outer end face of the connecting post 30, and the other end of the tension spring 1 is fixed to the outer end face of the inner mounting hole 21.

[0021] Furthermore, a metal sleeve 40 is fixed to the outer side of the polytetrafluoroethylene sleeve 20 by an adhesive or by a snap-fit ​​method. The metal sleeve 40 has an external through hole that is aligned with and communicates with the corresponding insertion through hole 22. The needle rod 31 is inserted into the corresponding external through hole. The inner sidewall of the external through hole and the inner sidewall of the insertion through hole 22 are in close contact with the outer sidewall of the needle rod 31, but this ensures that the needle rod 31 can move along the external through hole and the insertion through hole 22.

[0022] All PTFE sleeve bodies 2 do not have internal mounting holes 21 or other structures near their left and right ends, and the corresponding metal sleeve bodies 40 do not have external through holes near their left and right ends. Therefore, all needle bars 31 are located in the middle and the left and right parts of the middle of the metal sleeve body 40 and the PTFE sleeve body 2.

[0023] An axially extending protrusion 13 is formed on the outer wall between each pair of adjacent slots 12 of the main roller body 10. The outer wall of the protrusion 13 is in close contact with or near the inner wall of the polytetrafluoroethylene sleeve body 20. The protrusion 13 provides support between the polytetrafluoroethylene sleeve body 20 and the main roller body 10.

[0024] Furthermore, the left and right end faces of the main roller body 10 are fixedly connected to end plates 50 by multiple bolts, and the left and right end faces of the polytetrafluoroethylene sleeve body 20 and the metal sleeve body 40 are pressed against the inner end faces of the corresponding end plates 50.

[0025] The intermediate support shaft 11 extends out of the outer end of the central through hole formed in the middle of the corresponding end plate 50.

[0026] Of all the needle bars 31 described, the needle bars 31 extending radially on the same horizontal plane are a ring structure, which are evenly distributed on the outer side wall of the polytetrafluoroethylene sleeve 20 with the central axis of the polytetrafluoroethylene sleeve 20 as the center.

[0027] The distance between the needle bars 31 of each two adjacent ring structures is equal.

[0028] One end of the tension spring 1 is pressed against and adsorbed onto the end face of the permanent magnet ring 39 fixed on the outer end face of the connecting column 30. This ensures the adsorption and fixation of the end of the tension spring 1, which will have a certain impact on the elastic force of the tension spring 1, but still ensures a certain extension and contraction effect.

[0029] When the needle bar 31 needs to be repaired or maintained in this embodiment, the two ends of the metal sleeve body 40 of this embodiment can be placed on two frames, the two end plates 50 can be disassembled, and then the polytetrafluoroethylene sleeve body 20 can be moved axially from the main roller body 10. Then, the needle bar 31 and its corresponding connecting post 30 can be replaced, which is convenient.

[0030] In this embodiment, when it collides or makes hard contact with the surrounding guide rollers or other components, the needle bar 31 can retract, making the needle bar 31 less likely to break and preventing excessive damage to the colliding components, thus reducing the probability of breakage and ensuring normal use.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
