Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a novel limit sensing device for a bottom plate. Background Art

[0002] Knitting machines are highly technologically advanced automated machines in the knitting machine industry, integrating computer digital control, electronic drive, and mechanical design. Knitting machines require a bottoming before knitting a fabric, and after the bottoming is completed, the bottoming fabric is pulled to continue the subsequent knitting. In order to reduce the waste of the bottoming fabric, the fabric is generally bottomed by a bottoming plate device.

[0003] A Chinese patent (application publication number CN114645373A) discloses an improved threading plate assembly, the movement process of the steel wire is as follows: the motor drives the capstan to move, the steel wire stretches outward around the capstan and passes through the through holes of each traction needle in turn, thereby pulling the yarn for weaving, and the motor stops working; when the fabric formed by the normal weaving of the yarn is successfully pulled by the pulling device, the motor is restarted and rotated in the reverse direction, the capstan rotates in the reverse direction and drives the steel wire to withdraw from the through hole of the traction needle. At this time, the fabric remains intact and the subsequent weaving work can be carried out smoothly, which reduces the consumption of yarn and has high production efficiency.

[0004] At present, the mechanical limit of wire feeding and drawing is the wire drawing disc limit. If the mechanical limit occurs repeatedly, the proportion of the wire drawing disc and the wire feeding wheel will be uncoordinated, resulting in chaotic wire feeding. In order to solve the above technical problems, the Chinese patent (application announcement number CN221166958U) discloses a bottom-lifting device for a sweater without bottom yarn, including a groove needle plate assembly, a main control board, and a transmission assembly arranged on the main control board, and a wire feeding assembly. The transmission assembly is respectively connected to the wire feeding assembly and the groove needle plate assembly to form a pumping structure between the wire feeding assembly and the groove needle plate assembly; it also includes a limit assembly and a steel wire test wheel. The limit assembly includes a limit sensor, which is arranged at the end of the groove needle plate and is connected to the transmission assembly. The steel wire test wheel is rotatably arranged on the main control board through a bearing. The steel wire test wheel is connected to the steel wire. When the steel wire slips, the steel wire test wheel stops rotating.

[0005] The limit assembly is based on the grounding principle. As long as the steel wire hits the limit sensor, the wire feeding will stop. This limit sensor is a hollow tube with a diameter of 1.5 directly welded to the end of the groove needle plate. However, the steel wire will frequently collide with the limit sensor under the continuous control of the capstan. In addition, since the limit sensor is an air tube structure, it is easy to cause the limit sensor and the steel wire to bend or even be damaged, thereby affecting the normal operation of the bottom plate. Therefore, it is necessary to improve the existing limit sensing device. Summary of the invention

[0033] The limit sensing device also includes a limit sensing column 30 attached to the other side of the base plate body 10 relative to the winch assembly. The limit sensing column 30 is provided with an open groove 31 on the side corresponding to the steel wire 20. The steel wire 20 and / or the limit sensing column 30 are provided with a conical structure 40 for facilitating effective contact between the two. That is to say, the conical structure 40 can be arranged on the steel wire 20 or on the limit sensing column 30 or respectively on the steel wire 20 and the limit sensing column 30. The steel wire 20 can be partially inserted into the open groove 31 and contact and cooperate with the limit sensing column 30 through the conical structure 40. At this time, the steel wire 20 and the limit sensing column 30 trigger grounding, and the winch assembly stops driving the steel wire 20 to continue to extend to the side of the limit sensing column 30.

[0034] The limit sensing column 30 of the utility model adopts a columnar structure, which can greatly enhance its strength and bending resistance, thereby improving its service life. In addition, an open groove 31 for partially inserting the steel wire 20 is provided on the side of the limit sensing column 30 facing the steel wire 20. At the same time, the steel wire 20 and / or the limit sensing column 30 are provided with a tapered structure 40 that facilitates effective contact between the two, thereby playing a guiding role, preventing the steel wire 20 from directly colliding with the end face of the limit sensing column 30 and generating a large impact force, thereby causing the limit sensing column 30 and the steel wire 20 to bend.

[0036] In some embodiments, the conical structure 40 is a conical groove arranged at the position of the opening groove 31 corresponding to the limit sensing column 30. The diameter of the conical groove expands from the side away from the steel wire 20 to the side adjacent to the steel wire 20. The conical groove plays a guiding role.

The limiting sensing column 30 is fixedly clamped on the connecting plate 51 by the elastic clamping force of the elastic clamping plate 53. Through the above arrangement, it is convenient to assemble the limiting sensing column 30 to the connecting member 50. The limiting sensing column 30 is fixedly clamped on the connecting plate 51 by the elastic clamping force of the elastic clamping plate 53 of the connecting member 50, thereby effectively improving the assembly efficiency of the limiting sensing column 30.

The positioning groove 12 plays a positioning role through the cooperation of the positioning column 512 and the positioning groove 12, and utilizes the elastic clamping force of the elastic clamp 53 to firmly attach the connecting piece 50 to the side of the base plate body 10. In order to make the positioning effect of the positioning column 512 better, the outer diameter of the positioning column 512 can be slightly increased in the utility model, and a notch groove 5121 is opened in the center of the positioning column 512, and the notch groove 5121 extends along the protruding direction of the positioning column 512. Through this arrangement, the positioning column 512 has a certain elasticity so that it can be better clamped in the positioning groove 12.

The connecting member 50 is installed on the base plate body 10 by clamping the clamping portion 513 with the clamping slot 13. The height of the clamping portion 513 matches the height of the clamping slot 13 to limit the vertical movement of the connecting member 50. Specifically, the connecting member 50 includes a connecting plate 51, a bending portion 52 connected to the connecting plate 51, and an elastic clamp 53 connected to the other side of the bending portion 52.
