Description

Technical Field

[0001] This utility model belongs to the field of warp knitting machine technology, specifically relating to a weft laying carriage with a self-locking function. Background Technology

[0002] The weft laying mechanism of a warp knitting machine generally includes a weft laying carriage, which lays the yarn by moving the weft laying carriage longitudinally and laterally.

[0003] Chinese Patent Publication No. CN111648022A discloses a weft-laying mechanism and method for a web-laying machine, including a sliding weft-laying trolley. The weft-laying trolley is equipped with a weft-laying trolley guide plate, which has several spaced-apart guide holes through which yarn can pass. However, the guide plate does not have a self-locking function. When the yarn is continuously laid, the weft-laying trolley will retract as it reaches the needle block and moves the yarn laterally around the needle block, causing the yarn to retract synchronously. The yarn cannot maintain a taut state, thus affecting the weft-laying effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem that the guide plate of the existing weft laying carriage does not have a self-locking function, and when the yarn is continuously laid, the weft laying carriage will retreat when it reaches the needle block and drives the yarn to move laterally around the needle block, causing the yarn to retreat synchronously and the yarn to be unable to maintain a taut state, thus affecting the weft laying effect. Now, a weft laying carriage with a self-locking function is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a weft-laying trolley with a self-locking function, comprising:

[0006] The yarn separating assembly has at least one component, which includes a reed body with reed eyes, a clamping plate with clamping eyes, and a transverse drive mechanism for pushing the clamping plate to reciprocate so that the reed eyes and clamping eyes are aligned or staggered. The reed eyes and clamping eyes are multiple and correspond one-to-one.

[0007] The yarn pressing assembly includes a yarn pressing plate and a longitudinal drive mechanism for driving the yarn pressing plate to rise and fall.

[0008] Furthermore, a cover plate is provided on the reed body, and the cover plate and the reed body enclose an installation cavity for installing the clamping plate.

[0009] Furthermore, there are two yarn separating components, namely an upper yarn separating component and a lower yarn separating component, and at least one yarn guiding mechanism is provided between the two for guiding the yarn.

[0010] Furthermore, there are two yarn guiding mechanisms, each of which includes two yarn guiding rods arranged side by side, forming a yarn guiding space between them for the yarn to pass through.

[0011] Furthermore, the weft-laying trolley also includes a base, and each yarn-guiding mechanism also includes a fixing block located at the end of the yarn-guiding rod to fix the two yarn-guiding rods. The fixing block is rotatably connected to the base, and a locking element for locking the fixing block is provided between the two.

[0012] Furthermore, a push rod and a pressing mechanism for driving the push rod to reciprocate along the width direction of the yarn separating assembly are provided between the two yarn guiding mechanisms.

[0013] Furthermore, a limiting plate for limiting the stroke of the push rod is installed on the base.

[0014] Furthermore, there are two yarn pressing plates, which are distributed on both sides of the lower yarn separating assembly in the width direction.

[0015] Furthermore, each pressure plate is an angular structure, which includes a pressing section for applying pressure to the yarn and a connecting section for connecting to the output end of the longitudinal movement drive mechanism.

[0016] Furthermore, the reed eye is rectangular in shape and is inclined along the length of the reed body, and the clamp eye is rectangular in shape and is inclined along the length of the clamp plate.

[0017] The beneficial effects of this utility model are: This utility model uses a clamp that moves back and forth along the length of the reed to lock or unlock the yarn in the reed eye, which satisfies the requirement that the yarn can freely pass through the reed eye during normal laying, reach the needle block and be locked during the lateral movement, ensuring that the yarn is always in a taut state, thereby improving the weft laying efficiency.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0035] like Figures 1-4 As shown, a weft-laying trolley with a self-locking function includes a yarn-separating assembly 1 and a yarn-pressing assembly 2:

[0036] The number of yarn separating components 1 is at least one, which includes a reed body 101 with reed eye 1011, a clamping plate 102 with clamping eye 1021, and a transverse drive mechanism 103 for pushing the clamping plate 102 to reciprocate so that the reed eye 1011 is aligned or staggered with the clamping eye 1021. The transverse drive mechanism 103 may be, but is not limited to, a cylinder or an electric cylinder.

[0037] The reed eyelets 1011 and clamp eyelets 1021 are multiple and correspond one-to-one. The multiple reed eyelets 1011 are arranged at intervals along the length direction of the reed body 101, and the multiple clamp eyelets 1021 are distributed at intervals along the length direction of the clamping plate 102. The clamping plate 102 is located above the reed body 101 and the two are in contact. The transverse drive mechanism 103 can drive the clamping plate 102 to reciprocate along the length direction of the reed body 101. When the reed eyelets 1011 and clamp eyelets 1021 are aligned, the yarn can pass through the clamping plate 102 and the reed body 101 in sequence for laying. When the reed eyelets 1011 and clamp eyelets 1021 are misaligned, the yarn can be locked.

[0038] The yarn pressing assembly 2 includes a yarn pressing plate 201 and a longitudinal shift drive mechanism 202 for driving the yarn pressing plate 201 to rise and fall. The longitudinal shift drive mechanism 202 can drive the yarn pressing plate 201 to press the yarn against the needle block.

[0039] During the laying process, the weft laying carriage moves back and forth longitudinally along the warp knitting machine. During the movement, the transverse drive mechanism 103 drives the clamping eye 1021 of the clamping plate 102 to align with the reed eye 1011 of the reed body 101. At this time, the yarn passes through the clamping eye 1021 and the reed eye 1011 in sequence for laying. When the weft laying carriage moves above the needle block, the longitudinal drive mechanism 202 can drive the yarn pressing plate 201 to press the yarn towards the needle block. The needle block inserts into the yarn. At this time, the weft laying carriage drives the yarn to move laterally around the needle block. During this process, the weft laying carriage first needs to move longitudinally a certain distance and then retreat. When retreating, the transverse drive mechanism 103 drives the clamping eye 1021 of the clamping plate 102 to be misaligned with the reed eye 1011 of the reed body 101 to lock a certain length of yarn so that the yarn of this length can pass around the needle block and remain taut, thereby improving the weft laying effect.

[0040] In some examples, the reed body 101 is covered with a cover plate 104, which has a through groove for the yarn to pass through. The extension length of the through groove is not less than the extension length of a plurality of reed holes 1011. The cover plate 104 and the reed body 101 enclose a mounting cavity for mounting a clamping plate 102. The shape of the mounting cavity matches the shape of the clamping plate 102, and the clamping plate 102 is confined within the mounting cavity, thereby improving the locking force of the yarn.

[0041] In some examples, there are two yarn separating components 1, namely an upper yarn separating component and a lower yarn separating component. When the two are locked synchronously, the locking effect of the yarn can be improved. At least one yarn guiding mechanism 3 for guiding the yarn is provided between the upper yarn separating component 1 and the lower yarn separating component 1.

[0042] In some examples, there are two yarn guiding mechanisms 3, each of which includes two yarn guiding rods 301 arranged side by side. The yarn guiding rods 301 are cylindrical rods, and a yarn guiding space is formed between the two yarn guiding rods 301 for the yarn to pass through.

[0043] In some examples, the weft-laying trolley also includes a base 4, and each yarn-guiding mechanism 3 also includes a fixing block 302 located at the end of the yarn-guiding rod 301 to fix the two yarn-guiding rods 301. The fixing block 302 is rotatably connected to the base 4 and a locking element for locking the fixing block 302 is provided between the two. The locking element can be a bolt. The bolt passes through the base 4 and the fixing block 302 in sequence and is threadedly connected to both. At this time, the yarn-guiding rod 301 can be fixed on the base 4. When the bolt is loosened, the yarn-guiding mechanism 3 can rotate. The two yarn-guiding mechanisms 3 can adjust their own positions according to the actual situation on site.

[0044] In some examples, a push rod 5 and a pressing mechanism 6 for driving the push rod 5 to reciprocate along the width direction of the yarn separating assembly 1 are provided between the two yarn guiding mechanisms 3. The push rod 5 is also a cylindrical rod and is used to adjust the yarn tension. The pressing mechanism 6 can be, but is not limited to, a cylinder or an electric cylinder, and its number can be, but is not limited to, one or two.

[0045] In some examples, the base 4 is equipped with a limiting plate 7 for limiting the stroke of the push rod 5. The limiting plate 7 has an angular structure and includes a fixing section for fixing to the base 4 and an abutting section for abutting against the push rod 5. There are two limiting plates 7, which correspond to the two ends of the push rod 5 respectively. The base 4 is provided with a waist-shaped groove extending along the width direction of the yarn separating assembly 1. The fixing section of the limiting plate 7 corresponds to the waist-shaped groove to achieve positional adjustment.

[0046] In some examples, there are two pressing plates 201, which are distributed on both sides of the lower yarn separating assembly 1 in the width direction. The two pressing plates 201 press the yarn between them toward the needle block.

[0047] Each pressing plate 201 has a guide rod fixed at both ends. The base 4 has a guide block for the guide rod to pass through and guide the guide rod. The guide block has a guide groove, and a linear bearing is installed between the guide groove and the guide rod.

[0048] In some examples, each pressure plate 201 is an angular structure, which includes a pressing section 2011 for applying pressure to the yarn and a connecting section 2012 for connecting to the output end of the longitudinal drive mechanism 202, the connecting section 2012 having a waist-shaped hole for adjusting the position.

[0049] In some examples, the eyelet 1011 is rectangular and is inclined along the length of the reed body 101, and the eyelet 1021 is rectangular and is inclined along the length of the clamping plate 102. The inclination angle is 45°±2°. Each eyelet 1011 and eyelet 1021 allows only one yarn to pass through.

[0050] The above description, based on the preferred embodiments of this utility model, provides inspiration. Those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification but must be determined according to the claims.
