Description

Technical Field

[0001] The utility model relates to the field of jacquard machine equipment, and more specifically, to a jacquard machine needle selection mechanism. Background Art

[0002] The needle selector is an accessory that selects the jacquard needles in the needle cylinder to achieve the purpose of knitting patterns. It drives the needle selector to work according to the electrical signal of the knitted fabric pattern combination, and energizes the electromagnetic coil of the needle selector to change the direction of the current, so that the cutter head swings left and right.

[0003] Existing needle selector such as Figure 1 As shown, it includes a needle selector body 1, a cutter head 2 and a shell, wherein a positioning rod 3 is provided on the needle selector body 1 for providing a swing point for the cutter head 2, wherein the positioning rod 3 is sleeved with an abutment plate 4, and then the abutment plate 4 is pressed onto the needle selector body 1 by the screw head of the bolt to fix the position of the positioning rod 3.

[0004] When the needle selector has a broken blade, it needs to be replaced and maintained. After replacing the new blade head 2, the position of the positioning rod 3 is fixed with bolts. However, during the fixing process, since the needle selector generally adheres to engine oil, in order to avoid slipping when tightening, it is easy to apply too much force and over-tighten, resulting in damage to the side wall of the needle selector body 1.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] A jacquard machine needle selection mechanism, such as Figure 2-Figure 5 As shown, it includes a needle selector body 5, a blade 6, a positioning guide column 7, an annular sheet 8 and a bolt 9. A prompting assembly is arranged on the needle selector body 5, wherein the prompting assembly includes a shell 10 fixedly arranged on the needle selector body 5, an abutting piece 11 for abutting the nut of the bolt 9 and a lifting piece 12 for prompting the user. The shell 10 is provided with an abutting interface for the abutting piece 11 to extend outward, so that when the bolt 9 is not screwed on, the abutting piece 11 extends outward from the shell 10 through the abutting interface, so that in the process of screwing on the bolt 9, the nut of the bolt 9 abuts against the abutting piece 11 and pushes the abutting piece 11 back into the shell 10, and the abutting piece 11 is slidably connected with the lifting piece 12, so as to push the lifting piece 12 to slide. An observation port for observing the lifting piece 12 is arranged on the shell 10, and the changes of the lifting piece 12 can be clearly seen through the observation port, so as to prompt the user that the bolt 9 is screwed in place, thereby effectively avoiding the problem of over-tightening due to excessive force and resulting in damage.

[0026] like Figure 2-Figure 5 As shown, a protrusion 13 for positioning the annular sheet 8 is provided on the housing 10, and a notch corresponding to the protrusion 13 is provided on the annular sheet 8, and a space is provided for the protrusion 13 through the notch, and an abutment interface is provided on the protrusion 13, so that the nut of the bolt 9 can be ensured to contact with the abutment 11 and the annular sheet 8 at the same time without changing the specifications of the bolt 9, thereby reducing the use cost.

[0027] like Figure 3 and Figure 5 As shown, a through slot 14 is provided on the abutting member 11 , and a limiting rod 15 passing through the through slot 14 is fixedly provided on the housing 10 , so that the abutting member 11 is prevented from falling off from the housing 10 by the cooperation between the through slot 14 and the limiting rod 15 .

[0028] The mutually contacting surfaces of the abutting member 11 and the lifting member 12 are both inclined. By utilizing the inclined contacting surfaces, a component force is formed when pushing occurs between the abutting member 11 and the lifting member 12, thereby ensuring stable movement.

[0029] An elastic element 18 is provided between the lifting member 12 and the housing 10 to push the lifting member 12 to move toward the abutting member 11. The elastic element 18 is used to ensure stable fit between the lifting member 12 and the abutting member 11, making the transmission between them more stable.

[0030] The lifting member 12 is provided with a receiving groove 16 for accommodating the elastic element 18 . The receiving groove 16 saves space, makes the overall structure more compact, and effectively avoids the problem of radial deformation of the elastic element 18 .

[0031] like Figure 5 As shown, a color coating 17 is coated on one side of the lifting member 12 close to the observation port, and the color coating 17 is used to form a color difference on the surface of the lifting member 12, so that the user can intuitively see the changes.

[0032] Working principle: After installing the new blade 6, embed the positioning guide column 7 to fix the position, and align the notch on the annular sheet 8 with the position of the raised portion 13, and then screw on the bolt 9. During the process of screwing on the bolt 9, the nut of the bolt 9 will abut against the abutment 11 and push the abutment 11 downward, so that the abutment 11 pushes the lifting member 12 to move toward the elastic element 18 through the inclined surface, and then the position of the color coating 17 on the lifting member 12 coincides with the position of the observation port, thereby prompting the user that it has been screwed into place.

[0033] 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 essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, 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 be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
