Description

Technical Field

[0001] This utility model relates to the technical field of textile machinery, and in particular to a positioning sensing device for a bottom plate. Background Technology

[0002] The base-up device is a common structure used in knitting equipment. The base-up device usually includes a steel wire and a take-up and feed mechanism. When base-up is required, the take-up and feed mechanism feeds out the steel wire, so that the steel wire passes through each base-up loop and pulls the base-up loop to realize base-up knitting. After base-up is completed, the take-up and feed mechanism retracts the steel wire, so that the steel wire exits from each base-up loop.

[0003] Currently, the mechanical limits for yarn feeding and drawing are all based on the drawing disc. Repeated mechanical limiting can lead to an imbalance between the drawing disc and the feeding wheel, resulting in chaotic yarn feeding. To address this technical problem, Chinese patent (application publication number CN221166958U) discloses a bottomless yarn sweater bottom-raising device. When the steel wire is fed to the bottom, a limiting component is needed to stop the yarn feeding / drawing to prevent overfeeding / drawing and damage to components. The limiting component includes a limiting sensor based on a grounding principle. The yarn feeding stops as soon as the steel wire touches the sensor. This sensor is a 1.5mm diameter hollow tube directly welded to the end of the slotted needle plate. When the steel wire is fed to the bottom, the head of the wire contacts the limiting sensor, thereby driving the motor to stop working and stopping the yarn feeding.

[0004] However, the steel wire will frequently collide with the limit sensor under the continuous control of the wire feeding mechanism. In addition, since the limit sensor is a hollow tube structure, it is easy for the limit sensor and the steel wire to bend or even be damaged. Furthermore, the steel wire and the limit sensor are in rigid contact, and the contact end between the steel wire and the limit sensor is prone to wear or even damage, thus affecting the normal operation of the base plate. Therefore, it is necessary to improve the existing positioning sensing device. Summary of the Invention

[0005] The purpose of this invention is to provide a positioning sensing device for a bottom plate. The elastic buffer unit makes flexible contact with the steel wire through elastic deformation or elastic expansion, avoiding bending and damage to the steel wire and the sensing unit in contact with the steel wire, thereby improving the service life of the wire take-up positioning sensing component and the steel wire.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bottom-raising plate positioning sensing device, comprising a bottom-raising plate body and a bottom-raising device, the bottom-raising plate body being provided with a wire-retracting positioning sensing component and a plurality of bottom-raising needles arranged on the bottom-raising plate body, the bottom-raising device including a steel wire and a wire feeding mechanism, one end of the steel wire extending toward the needle hole of the bottom-raising needle, the other end of the steel wire extending toward the wire-retracting positioning sensing component, the wire feeding mechanism being used to drive the steel wire to feed and draw the wire, the wire-retracting positioning sensing component including a grounded elastic buffer unit and a connecting unit for attaching the elastic buffer unit to the bottom-raising plate body, when the steel wire touches the elastic buffer unit, it will force the elastic buffer unit to elastically deform or elastically expand and contract, the elastic buffer unit flexibly contacts the steel wire through elastic deformation or elastic expansion and contraction, at this time the steel wire and the elastic buffer unit trigger grounding, and the wire feeding mechanism stops driving the steel wire to extend toward the side of the elastic buffer unit.

[0007] Furthermore, the elastic buffer unit is an elastic clamping pair, which has an elastic clamping end and a grounding end. When the elastic clamping end is pushed by the steel wire, it will be stretched open by a certain distance and the steel wire will be limited and fixed.

[0008] Furthermore, the elastic clamping end includes a first spring piece and a second spring piece. The first spring piece and the second spring piece are connected to the grounding end through an elastic arm. The first spring piece and the second spring piece are in contact with each other or at a certain distance, and the distance between them is less than the diameter of the steel wire. The end of the elastic clamping end facing the steel wire is provided with a guide structure for guiding the steel wire to be inserted.

[0009] Furthermore, the guiding structure includes an inclined guide piece, which is disposed at the end of the first and second spring pieces facing the steel wire. The two guide pieces are inclined in a spreading manner so that the steel wire can spread the first and second spring pieces apart with the help of the two guide pieces.

[0010] Furthermore, two sets of guide plates are symmetrically arranged on both sides of the first and second spring plates, and the guide plates are integrally formed on the corresponding spring plates.

[0011] Furthermore, the connecting unit is a connecting frame, which is attached to the base plate body through a first connecting end. The connecting frame is provided with an installation area for installing the elastic clamping pair. The elastic clamping pair is fixedly installed in the installation area of ​​the connecting frame. The connecting frame is provided with a channel facing the middle of the elastic clamping end of the elastic clamping pair. The steel wire can pass through the channel and touch the elastic clamping end.

[0012] Furthermore, the base plate body is provided with threaded holes, and the first connecting end of the connecting frame is provided with a transversely arranged strip groove. The connecting frame is fixedly installed on the base plate body by fasteners cooperating with the threaded holes. The position of the connecting frame in the length direction of the base plate body can be adjusted by adjusting its transverse position.

[0013] Furthermore, the connecting unit includes a connecting plate attached to the base plate body, and the wire take-up sensing component includes a sleeve, a plug, an elastic element, and an abutment block. The sleeve is connected to the connecting plate, and the sleeve is provided with a receiving cavity arranged along the length direction of the base plate body. The plug is fixedly connected to the other end of the sleeve relative to the steel wire, and the plug is grounded. The abutment block is slidably disposed in the receiving cavity, and the elastic element is disposed between the abutment block and the plug. The abutment block, the elastic element, and the plug are made of conductive material. When the steel wire touches the abutment block, the abutment block will force the elastic element to elastically expand and contract, thereby making the abutment block and the steel wire flexibly contact each other.

[0014] Furthermore, the sleeve is provided with a flared opening, the diameter of which expands from left to right, through which the steel wire is guided into the receiving cavity and contacts the abutment block.

[0015] Furthermore, the take-up positioning sensing component is disposed on the base plate body and on the other side relative to the take-up and feed mechanism.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, a bottom-raising plate positioning sensing device includes a bottom-raising plate body 10 and a bottom-raising device 20. The bottom-raising plate body 10 is provided with a wire-retrieving positioning sensing component 30 and a plurality of bottom-raising needles 11 arranged on the bottom-raising plate body 10. The bottom-raising device 20 includes a steel wire 21 and a wire-retrieving mechanism 22. One end of the steel wire 21 extends toward the needle hole of the bottom-raising needle 11, and the other end of the steel wire 21 extends toward the wire-retrieving positioning sensing component 30. The wire-retrieving mechanism 22 is used to drive the steel wire 21 to feed and draw wire. That is, when the wire-retrieving mechanism 22 is driven in the forward direction, the steel wire is fed toward the needle hole of the bottom-raising needle 11, and when the wire-retrieving mechanism 22 is driven in the reverse direction, the steel wire is retrieving toward the needle hole of the bottom-raising needle 11.

[0026] In this invention, the take-up positioning sensing component 30 is located at the lower end of the base plate body 10 and on the other side of the take-up and feed mechanism 22. The take-up positioning sensing component 30 includes an elastic buffer unit 31 grounded and a connecting unit 32 for attaching the elastic buffer unit 31 to the base plate body 10. The elastic buffer unit 31 is grounded. When the steel wire 21 touches the elastic buffer unit 31, it will force the elastic buffer unit 31 to elastically deform or elastically stretch. The elastic buffer unit 31 makes flexible contact with the steel wire 21 through elastic deformation or elastic stretch. At this time, the steel wire 21 and the elastic buffer unit 31 trigger grounding. That is, when the steel wire 21 contacts the elastic buffer element 31, grounding will be triggered. The electronic control system will feed back a signal to the take-up and feed mechanism 22 so that the take-up and feed mechanism 22 stops driving the steel wire 21 to extend to the side of the elastic buffer unit 31, that is, the take-up and feed mechanism 22 stops the wire drawing action.

[0027] In some embodiments, the elastic buffer unit 31 is an elastic clamping pair 311, which has an elastic clamping end 312 and a grounding end 313. After being pushed by the steel wire 21, the elastic clamping end 312 will undergo elastic deformation and be stretched a certain distance to limit and fix the steel wire 21. The elastic clamping end 312 makes flexible contact with the steel wire 21 through elastic deformation. The grounding end 313 of the elastic clamping pair 311 is grounded through a grounding cable.

[0028] In some embodiments, the elastic clamping end 312 includes a first spring piece 3121 and a second spring piece 3122. The first spring piece 3121 and the second spring piece 3122 are connected to the grounding end 313 through an elastic arm 314. The first spring piece 3121 and the second spring piece 3122 are in contact with each other or at a certain distance, and the distance between them is less than the diameter of the steel wire 21. The end of the elastic clamping end 312 facing the steel wire 21 is provided with a guide structure for guiding the steel wire 21 to be inserted. The first elastic and the second spring piece 3122 undergo elastic deformation through the elastic arm 314. The distance between the two elastic arms 314 is reduced from bottom to top, that is, reduced from the grounding end 313 towards the corresponding spring piece.

[0029] In some embodiments, the guiding structure includes an inclined guide piece 315, which is disposed at one end of the first spring piece 3121 and the second spring piece 3122 facing the steel wire 21. The two guide pieces 315 are inclinedly arranged in a spreading manner so that the steel wire 21 can spread the first spring piece 3121 and the second spring piece 3122 with the help of the two guide pieces 315.

[0030] In some embodiments, two sets of guide plates 315 are symmetrically arranged on both sides of the first spring plate 3121 and the second spring plate 3122. The guide plates 315 are integrally formed on the corresponding spring plates. The symmetrical arrangement of the two sets of guide plates 315 serves to balance the weight on both sides of the spring plate. On the other hand, when one of the guide plates 315 is damaged, the elastic clamping pair 311 can be swapped, so that the guide plate 315 on the other side can be used to guide the steel wire 21, thereby improving the utilization rate and service life of the elastic clamping pair 311.

[0031] In some embodiments, the connecting unit 32 is a connecting frame 321. The connecting frame 321 is attached to the base plate body 10 through a first connecting end 3211. The connecting frame 321 is provided with a mounting area 3212 for mounting the elastic clamping pair 311. The elastic clamping pair 311 is fixedly mounted in the mounting area 3212 of the connecting frame 321. The connecting frame 321 is provided with a channel facing the middle of the elastic clamping end 312 of the elastic clamping pair 311. The steel wire 21 can pass through the channel and touch the elastic clamping end 312.

[0032] In some embodiments, the base plate body 10 is provided with a threaded hole 12, and the first connecting end 3211 of the connecting bracket 321 is provided with a transversely arranged strip groove. The connecting bracket 321 is fixedly installed on the base plate body 10 by fasteners cooperating with the threaded hole 12. The position of the connecting bracket 321 in the length direction of the base plate body 10 can be adjusted by adjusting its transverse position. When it is necessary to adjust the position of the connecting bracket 321, first loosen the fasteners, then adjust the transverse position of the connecting bracket 321, and tighten the fasteners after the transverse position of the connecting bracket 321 is adjusted.

[0033] In some embodiments, the connecting unit 32 includes a connecting plate attached to the base plate body 10, and the wire take-up sensing component 30 includes a sleeve 316, a plug 3161, an elastic element 3162, and an abutment block 3163. The sleeve 316 is connected to the connecting plate, and a receiving cavity is provided inside the sleeve 316 along the length direction of the base plate body 10. The plug 3161 is fixedly connected to the other end of the sleeve 316 relative to the steel wire 21, and the plug 3161 is grounded. The abutment block 3163 is slidably disposed in the receiving cavity. The elastic element 3162 is disposed between the abutment block 3163 and the plug 3161. The abutment block 3163, the elastic element 3162, and the plug 3161 are made of conductive materials. When the steel wire 21 touches the abutment block 3163, the abutment block 3163 will force the elastic element 3162 to elastically expand and contract, thereby making the abutment block 3163 flexibly contact the steel wire 21.

[0034] In some embodiments, the sleeve 316 is provided with a flared opening, the diameter of which expands from left to right, and the steel wire 21 is guided into the receiving cavity through the flared opening to contact the abutment block 3163.

[0035] In some embodiments, the take-up positioning sensing component 30 is disposed on the base plate body 10 and on the other side relative to the take-up and feed mechanism 22. A guide tube 14 for guiding the movement of the wire 21 is disposed between the take-up and feed mechanism 22 and the take-up positioning sensing component 30. A plurality of support plates 13 are disposed on the base plate body 10 between the take-up positioning sensing component 30 and the take-up and feed mechanism 22. The support plates 13 are used to support the guide tubes 14.

[0036] In summary, this utility model has the following beneficial effects:

[0037] The positioning sensing device for the bottom plate of this utility model uses the elastic deformation or elastic extension of the elastic buffer unit 31 of the winding positioning sensing component 30 to flexibly contact the steel wire 21, thereby preventing the steel wire 21 and the sensing unit in contact with the steel wire 21 from bending and being damaged, thus improving the service life of the winding positioning sensing component 30 and the steel wire 21. Specifically, when the steel wire 21 is connected to the elastic buffer unit 31, the steel wire 21 and the elastic buffer unit 31 are triggered to ground, and the electronic control system will feed back a signal to the winding and feeding mechanism 22, so that the winding and feeding mechanism 22 stops driving the steel wire 21 to extend to the side of the elastic buffer unit 31, that is, the winding and feeding mechanism 22 stops the wire drawing action.
