Description

Technical Field

[0001] This utility model relates to the field of circular weft knitting machine technology, and in particular to a feeding buffer positioning device for a single-sided circular weft knitting machine. Background Technology

[0002] A weft knitting machine is a type of knitting machinery used to produce weft-knitted fabrics. It works by feeding yarn into knitting needles along the weft direction and forming loops that are interlocked. The main types of weft knitting machines include circular weft knitting machines and flat weft knitting machines. The structural differences lead to different application scenarios. Weft knitting machines use one or more yarns to be continuously fed into the fabric along the weft direction. The yarns are then bent into loops by knitting needles and interlocked to form knitted fabrics. This process is called weft knitting, and the resulting fabrics have good elasticity and extensibility.

[0003] After the textiles are rolled into rolls, the operator opens the knitting machine door and assists in unloading the textiles inside. The existing unloading buffer positioning device of the single-sided circular weft knitting machine only uses an adjustable positioning baffle for simple limiting when unloading the textiles. During the unloading process, the textiles are prone to deviate on the slide and cannot be accurately positioned and neatly transported out of the outlet, which reduces work efficiency and may cause jamming and damage to the textiles.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] The feeding buffer positioning device for a single-sided circular weft knitting machine disclosed in this utility model is mainly applied to scenarios where the feeding buffer positioning device of the existing single-sided circular weft knitting machine only relies on adjustable baffles for limiting, and the textile is prone to shifting on the slide during feeding, resulting in uneven output, reduced efficiency, and possible damage to the fabric due to jamming.

[0020] Reference Figure 1 A single-sided circular weft knitting machine feeding buffer positioning device includes: a weft knitting machine body 1, an inclined slide 2 provided at the opening of the weft knitting machine body 1, and a slide bracket 3 fixedly connected to the lower side of the inclined slide 2; a buffer detection component 5, disposed inside the lower end of the inclined slide 2, the buffer detection component 5 being used to buffer and protect the textiles during feeding and to detect whether the textiles have deviated; and a correction component 7, disposed inside the buffer detection component 5, the correction component 7 being used to provide auxiliary buffering for the textiles during feeding while correcting any textiles that have deviated.

[0021] Reference Figures 1-3In a preferred embodiment, the buffer detection assembly 5 includes: a disc shaft 502, two disc shafts 502 are respectively connected to two rotating holes opened on the inner wall of opposite sides of the lower end of the inclined slide 2 via bearings, and multiple through holes are equally spaced on opposite sides of the two disc shafts 502. One set of opposite through holes is connected to a bidirectional lead screw 504 via bearings, and the remaining sets of opposite through holes are respectively fixedly connected to fixed guide rods 503; a rotary motor 501 is fixedly connected to the outer wall of the lower end of the inclined slide 2, and the drive end of the rotary motor 501 is fixedly connected to one of the disc shafts 502 via a coupling; and an adjusting motor 505 is fixedly connected to the outer wall of the other disc shaft 502, and the drive end of the adjusting motor 505 is connected to one end of the bidirectional lead screw 504 via a coupling.

[0022] In this scheme, the buffer detection component 5 further includes: two movable circular blocks 506, which are respectively sleeved on the outer walls of the bidirectional lead screw 504 and multiple fixed guide rods 503. The two movable circular blocks 506 can move closer and further away from each other along the multiple fixed guide rods 503 under the action of the bidirectional lead screw 504. Multiple connecting plates 507 are fixedly connected to the outer walls of the two movable circular blocks 506 at equal intervals by bolts; buffer springs 509, one end of multiple buffer springs 509 is fixedly connected to one side of the connecting plate 507 at equal intervals, and the other end of multiple buffer springs 509 is fixedly connected to the inner wall of the opening of the sliding buffer plate 510. The opening of the sliding buffer plate 510 is slidably connected to the outer wall of the connecting plate 507.

[0023] In this scheme, the buffer detection component 5 also includes: a pressure sensor 511, which is disposed on the side of the connecting plate 507 near the buffer spring 509; an alarm 512 is disposed on one side of the connecting plate 507, which is located directly below the pressure sensor 511; and a fixing block 508, which is fixedly connected to the side of the connecting plate 507 away from the sliding buffer plate 510.

[0024] When unloading textile rolls, the bidirectional lead screw 504 is rotated by the adjusting motor 505, thereby controlling the buffer detection components 5 at both ends to move closer or further apart until they are adjusted to a suitable distance. This allows for rapid adjustment based on the size of the textile roll. The offset of the textile roll is determined by whether the pressure value received by the pressure sensor 511 is the same, and the offset is detected and corrected immediately to prevent the textile roll from jamming and being damaged. At the same time, the rotary motor 501 drives the disc shaft 502 to rotate, so that the textile roll clamped between the correcting rubber block 704 and the sliding buffer plate 510 is smoothly and neatly transferred to the discharge plate 13, avoiding wasted time in later alignment.

[0025] Reference Figures 2-4In a preferred embodiment, the correction component 7 includes: an electric telescopic rod 702, fixedly connected to the upper side of the connecting plate 507, with a sliding plate 701 fixedly connected to the telescopic end of the electric telescopic rod 702, the sliding plate 701 sliding on the outer wall of the fixed block 508, a rotating hole being provided on the upper inner wall of the sliding plate 701, and a rotating shaft 706 being connected to the two opposing rotating holes via bearings, with rotating housings 703 fixedly connected to the two ends of the rotating shaft 706 located outside the sliding plate 701; torsion springs 705, two torsion springs 705 respectively sleeved on the outer walls of the two ends of the rotating shaft 706 located outside the sliding plate 701, the two torsion springs 705 respectively located inside the corresponding rotating housings 703, one end of the two torsion springs 705 being fixedly connected to the two outer walls of the sliding plate 701, and the other end of the two torsion springs 705 being fixedly connected to the corresponding rotating housings 703; and a correction rubber block 704, fixedly connected to the outer wall of the rotating shaft 706, the correction rubber block 704 being able to rotate inside the sliding plate 701.

[0026] When unloading textile rolls, a corrective rubber block 704 is set up to rotate into the inner groove of the sliding plate 701 under the action of the weight of the textile roll, overcoming the elastic force of the torsion spring 705. The reaction force of the torsion spring 705 is transmitted to the textile roll through the corrective rubber block 704 for initial buffering and deceleration, so as to prevent the textile roll from rebounding violently when it comes into contact with the buffer detection component 5 due to excessive speed.

[0027] Reference Figure 1 and Figure 5 In a preferred embodiment, a sliding groove is provided on the upper side of the inclined slide 2. Two positioning baffles 6 are slidably connected inside the sliding groove. Multiple rollers 8 are connected at equal intervals inside the two positioning baffles 6 via bearings. The outer walls of the multiple rollers 8 are provided with the same protective belt 11. Adjusting blocks 9 are fixedly connected to the outer walls of the inclined slide 2 near the two positioning baffles 6. Threaded holes are provided on opposite sides of the two adjusting blocks 9. Rotating screws 10 are screwed into the two threaded holes, and one end of each rotating screw 10 is connected to the corresponding positioning baffle via bearings. 6 is located inside one end of the inclined slide 2; the discharge end of the inclined slide 2 is fixedly connected to two discharge brackets 4, and discharge holes are opened at equal intervals on the opposite side of the two discharge brackets 4. The discharge rods 14 are slidably connected inside the two sets of opposite discharge holes, and discharge plates 13 are fixedly connected to one end of the two sets of opposite discharge rods 14 respectively. Adjustable telescopic rods 12 are fixedly connected to the opposite outer sides of the two discharge brackets 4 respectively. The telescopic ends of the two adjustable telescopic rods 12 pass through the remaining set of opposite discharge holes of the corresponding discharge brackets 4 and are fixedly connected to the corresponding discharge plates 13.

[0028] When unloading textile rolls, two opposing rotating screws 10 are used to move two positioning baffles 6 closer or further apart until they are adjusted to a suitable distance. This allows for adjustment based on the size of the textile roll at any time. Meanwhile, multiple rollers 8 and protective belts 11 on the positioning baffles 6 come into contact with the textile rolls during unloading. Due to rolling friction, the surface of the textile rolls will not be damaged.

[0029] Working principle: After the textiles inside the weft knitting machine body 1 are processed into large rolls, the operator assists in rolling the textile rolls out to the inclined slide 2 for unloading at the opening of the weft knitting machine body 1. Before this, the distance between the two positioning baffles 6, the distance between the two buffer detection components 5, and the distance between the two discharge plates 13 are adjusted according to the size of the textile rolls. First, by rotating the two opposing rotating screws 10, the two positioning baffles 6 are brought closer or further apart until the appropriate distance is achieved. At the same time, the multiple rollers 8 and the protective belt 11 on the positioning baffles 6 come into contact with them during the unloading process of the textile rolls. The kinetic friction prevents damage to the surface of the textile roll. Secondly, by controlling the adjusting motor 505 to rotate the bidirectional lead screw 504, the buffer detection components 5 at both ends are controlled to move closer or further apart until a suitable distance is reached. Finally, by controlling the two opposing adjusting telescopic rods 12, the two discharge plates 13 are moved to the appropriate positions. After all components are adjusted, the textile roll is unloaded. As the textile roll rolls down along the inclined slide 2, it first passes through the correcting rubber block 704 in the correcting component 7. Under the weight of the textile roll, the correcting rubber block 704 overcomes the elastic force of the torsion spring 705 and rotates to the sliding plate 701. In the inner groove, the reaction force of the torsion spring 705 is transmitted to the textile roll through the corrective rubber block 704 for initial buffering and deceleration, preventing the textile roll from rebounding violently when it comes into contact with the buffer detection component 5 due to excessive speed. Subsequently, the textile roll contacts the sliding buffer plate 510 in the buffer detection component 5 and is buffered and stopped under the action of the buffer spring 509. During this process, if the textile roll does not deviate, the pressure values ​​of the two sliding buffer plates 510 on the corresponding pressure sensors 511 are the same. If the textile roll deviates, the pressure values ​​received by the two pressure sensors 511 are not equal, and then the first... Time triggers the retraction of the electric telescopic rod 702, and the correcting rubber block 704 straightens the misaligned textile roll until the pressure values ​​of the pressure sensors 511 are the same. If the pressure values ​​of the pressure sensors 511 remain unequal for an extended period, the alarm 512 is triggered to notify the staff for manual adjustment. When the pressure values ​​of the pressure sensors 511 are the same, the rotary motor 501 is turned on to drive the disc shaft 502 to rotate, so that the textile roll clamped between the correcting rubber block 704 and the sliding buffer plate 510 is smoothly and neatly transferred to the discharge plate 13, where the staff collects it, and then the above operation is repeated.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
