Description

Technical Field

[0001] This invention relates to a method for preventing the return of single filaments by the loop-joining needle during loop transfer knitting on a horizontal knitting machine, belonging to the field of textile technology. Background Technology

[0002] The flat knitting machine has a pair of needle plates 1 arranged symmetrically front and back, such as Figure 1 The needle plate 1 has several parallel needle grooves, each groove containing a knitting needle 10 and a corresponding needle foot. Each needle plate 1 has a laterally movable triangular base plate 2 on top. Figure 2 The triangular base plate is provided with several knitting triangles 20 that act on the needle feet, so that the knitting needles move up and down in the needle groove through the needle feet. The upward and downward movements of the knitting needles 10 in the needle groove form the starting segment A1 and the return segment A2 of the knitting needles 10 in each movement cycle in the needle groove, respectively. The return segment A2 can be one segment or divided into two segments, such as... Figure 2 The first backstitch segment A21 and the second backstitch segment A22. The movement of the needle is controlled by different knitting triangles 20, which push the needle to form different needle movement trajectories A to complete different knitting operations such as forming loops, gathering loops, and shifting loops. A sinker 4 is located at the front end of the needle plate 1 and on both sides of the front end of each needle groove. A sinker triangle 6, acting on the sinker 4, is provided on the upper side of the triangular base plate 5. The sinker heel 40 of the sinker 4 rotates under the action of the sinker triangle 6, causing the sinker's acting end 41 to act on the loop or the arc between loops hanging on the knitting needle 10. The sinker triangle 6 moves upward or downward on the triangular base plate 5, thus positioning itself in a position where it acts on or does not act on the sinker 4.

[0003] The sinker plate 4 is designed to prevent the fabric from floating up during the cast-on section due to insufficient tension. However, in current knitting of sweater pieces or full-body knitting, a large number of decreases and increases are required. At this time, the fabric floats on the bobbin opening 3 between the two needle plates due to a lack of tension. As the transfer needles gradually withdraw during transfer knitting, if the loop floats on the bobbin opening 3 when the receiving needle returns to its starting position, the tip of the needle hook is very likely to insert into part of the yarn in the loop, forming a monofilament, thus causing problems with the appearance and quality of the fabric, especially with multi-strand yarns with low twist. However, existing flat knitting machines typically have two sinker triangles (6) for each cycle, corresponding to the starting and returning stitches respectively, and positioned at high and low levels respectively. The sinker is used in the starting stitch section but not in the returning stitch section. This is because, for flat knitting machines, most of the knitting requires feeding yarn to the needles ("yarn feeding"). Since the needles are in the returning stitch section, if the sinker were working, it would hinder yarn feeding, therefore the sinker cannot function. Although shift knitting does not require yarn feeding, improper position and depth of the sinker's action on the bobbin loop and the arc between loops in the returning stitch section can cause side effects such as yarn breakage and instability during shift knitting; therefore, the sinker also does not function in this case.

[0004] Therefore, the problem of monofilament in the shift knitting process of existing horizontal knitting machines has not been well solved. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a method for preventing the return of single filaments of the loop needle in the loop-joining section of the knitting process by having the sinker in the working position.

[0006] To achieve the above objectives, the technical solution proposed by this invention is as follows: a method for preventing the return of a single filament from a loop-connecting needle during loop transfer knitting on a horizontal knitting machine. The horizontal knitting machine has a pair of needle plates symmetrically arranged front and back and each equipped with several needles, several sinker plates placed at the front end of the needle plates, a triangular base plate with several knitting triangles that moves laterally above the needle plates, a sinker triangular base plate with sinker triangles connected to the side of the triangular base plate, and a pushing component for moving the sinker triangles. During loop transfer knitting, the loops on the loop-connecting needles are transferred to the loop-connecting needles. The sinker plates are in a working position or a non-working position that does not act on the arc between the loops due to the action of the sinker triangles. In the starting section of loop transfer knitting, the sinker plates are in a working position or a non-working position; in the return section of loop transfer knitting, the sinker plates are in a working position.

[0007] A further design of the above technical solution is as follows: the return pin section includes a first return pin section and a second return pin section; the sinker is in the working position in the first return pin section and the second return pin section respectively, or is only in the working position in the second return pin section.

[0008] The settling triangle is pushed up to a high position or down to a low position by the pushing component. It consists of a settling base plate, a starting triangle set on the settling base plate with a pushing slope and a lower limit plane, and a returning triangle set on the settling base plate with a pushing slope and an upper limit plane. The returning triangle and the starting triangle are arranged opposite each other, and the returning triangle and the starting triangle form the running path of the settling plate heel.

[0009] A preferred embodiment of the above technical solution is as follows: there are two sinking triangles, which are symmetrically arranged on the left and right sides and can slide up and down relative to the center line of the knitting area formed by several knitting triangles on the opposite triangular base plate, and respectively correspond to the starting section and the back section.

[0010] The length of the running path on each settling triangle is longer than the starting or returning section, so as to control the settling plate throughout the starting or returning section; or the length of the running path on the settling triangle is shorter than the starting or returning section, so as to control the settling plate locally in the starting or returning section.

[0011] Another preferred embodiment of the above technical solution is: there are four sinking triangles, arranged in pairs, with two sinking triangles in each pair arranged left and right. The two sets of sinking triangles are symmetrically arranged on the left and right sides of the center line of the knitting area formed by several knitting triangles on the triangular base plate, and respectively correspond to the starting stitch section and the back stitch section.

[0012] Each group of two settlement triangles and the adjacent ends of two settlement triangles adjacent to each other are provided with step structures that can fit together to accommodate and form the running path.

[0013] In each group, the two settling triangles are either both set at a high position or both set at a low position, forming a settling plate needle heel running path that is longer than the starting or returning needle section, so as to control the settling plate throughout the starting or returning needle section; or in each group, the two settling triangles are set at a high position and a low position respectively, forming a settling plate needle heel running path that is shorter than the starting or returning needle section, so as to control the settling plate locally during the starting or returning needle section.

[0014] The pushing assembly includes a sliding pin and a push block that is pushed linearly. The push block has a groove with a width adapted to the sliding pin and containing an inclined guide surface. The sliding pin is connected to a settling triangle and slidably placed in the groove. The settling triangle moves upward or downward when the push block is pushed and the sliding pin slides along the inclined guide surface in the groove.

[0015] The push block is provided with one or more grooves, and each groove is slidably connected to at least one sliding pin connected to the settlement triangle. When the push block is pushed, it causes one or more settlement triangles to move up and down.

[0016] The beneficial effects of this invention are as follows: This invention is designed to place the sinker in the working position during the loop return section of shift knitting. By utilizing the effect of the sinker on the arc between the loops in the working position, it prevents the knitting needle from snagging single filaments in the loop return section due to insufficient fabric tension, thus completely solving the problem of single filaments in the loop return section of shift knitting.

[0017] This invention controls the settling plate by controlling the settling triangle and the pushing component that moves the settling triangle up and down, so that the settling plate works in the corresponding return needle section, making the implementation method simple, reliable and easy to implement.

[0018] The present invention controls the settling triangles of the settling plate to be set in four pairs, symmetrically arranged in pairs. In each pair, the two settling triangles are pushed by the pushing component to make the two settling triangles both at the high position and one of them at the high position, forming a needle running path formed by the combination of settling triangles that is longer or shorter than the corresponding needle segment. This allows for full or partial control of the settling plate on the corresponding needle segment as needed, so as to maintain the fabric density in an optimal state.

[0019] In the four settling triangles of the present invention, which are arranged in pairs, the two adjacent settling triangles in each group and the adjacent ends of the two settling triangles in each group are respectively provided with stepped structures that can fit together and accommodate each other. The stepped structures are located on the running path so that when the settling plate heel runs to the docking point of the adjacent ends of the two settling triangles, a gap wider than the width of the heel (i.e. the running path) will not be generated, so that the heel runs smoothly and there is no concern about embedding into the seam.

[0020] The pushing component of the present invention mainly consists of a push block with a groove and a sliding pin that is set in the groove and connected to a settling triangle. By setting multiple grooves on a push block, multiple settling triangles are respectively set in the corresponding grooves through corresponding sliding pins. When the push block is pushed, the settling triangles slide up and down along the inclined guide surface in the groove through the corresponding sliding pins, making the structure of the entire pushing component very simple and the relative motion relationship accurate.

Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] The following embodiments can be used as follows: Figure 1 , 2 The method of the present invention is implemented on the horizontal knitting machine and triangular base plate shown, but is not limited to... Figure 1 , 2 The structure shown. Example

[0025] This embodiment is as follows: Figure 1 , 2 This is performed on the horizontal knitting machine and triangular base plate shown. A settling triangular base plate 5 is connected to the side of the triangular base plate 2, as shown. Figure 3As shown in section 3-1, the sinking triangle base plate 5 is provided with two sinking triangles 6 that are slidably connected to the sinking triangle base plate 5 at the position of each movement cycle of the knitting needle. The two sinking triangles 6 are symmetrically arranged on the sinking triangle base plate 5 with respect to the center line of the knitting area formed by several knitting triangles on the triangle base plate, and respectively correspond to the starting and returning stitches of the shift knitting.

[0026] Each settlement triangle 6 consists of a settlement base plate 60, a starting triangle 61 with a lifting ramp 611 and a lower limit plane 612, and a returning triangle 62 with a falling ramp 621 and an upper limit plane 622. The returning triangle 62 and the starting triangle 61 are arranged vertically opposite each other on the settlement base plate 60. The returning triangle 62 and the starting triangle 61 form a running path B of the settlement plate heel enclosed by the lifting ramp 611, the lower limit plane 612, the falling ramp 621 and the upper limit plane 622.

[0027] The two settlement triangles 6 on the settlement triangle base plate 5 are moved up and down by a pushing assembly. The pushing assembly includes a sliding pin 63 disposed on the settlement triangle 6 and a push block 7 for pushing the sliding pin 63. The push block 7 is driven by a driving element, such as a linear motor, and is pushed linearly. Figure 3 As shown in section 3-2, the push block 7 is provided with two sliding grooves 70 whose width is adapted to the sliding pin 63 and which contain inclined guide surfaces. The sliding pins 63 on the two sinking triangles 6 are slidably placed in the corresponding sliding grooves 70.

[0028] The aforementioned sinker triangle position setting is applied to loop transfer knitting. During loop transfer knitting, the loops on the transfer needle are transferred to the receiving needle. In the starting section, the corresponding sinker triangle 6 needs to be working, that is, in a high position. In the return section, the corresponding sinker triangle 6 can also be in a high position through the setting of the slide groove 70 and the pushing of the push block 7. That is, in the return section, the corresponding sinker triangle 6 is in the working position.

[0029] In this embodiment, the running path lengths on the two sinking triangles 6 are shorter than the corresponding needle starting and returning lengths, respectively, which allows for local control of the sinking plate in the starting or returning section.

[0030] In this embodiment, the front end of the sinker 6 in the return section of the knitting needle acts on the arc between the bobbin loop and the loop, which solves the problem of the single filament of the return needle; however, the local pressing of the loop in the starting section of the knitting needle affects the pressing effect on the loop and affects the fabric density.

[0031] In this embodiment, when corresponding to other knitting operations, the sinker triangle is pushed by the push block 7 to form a high or low position state of the sinker triangle that is adapted to the corresponding starting and returning stitches. These will not be described in detail here. Example

[0032] This embodiment also follows the example of... Figure 1 ,2 The operation is performed on the horizontal knitting machine and the triangular base plate shown. Two sinking triangles 6, slidably connected to the sinking triangle base plate 5, are also provided on the sinking triangle base plate 5 at the position corresponding to each movement cycle of the knitting needle. Figure 4 In section 4-1, the two sinking triangles 6 are symmetrically arranged on the sinking triangle base plate 5 with respect to the center line of the knitting area formed by several knitting triangles on the base plate, and respectively correspond to the starting and returning stitches of the loop knitting. In this embodiment, the push block 7 has the same structure as in embodiment one. During loop knitting, the setting of the sliding groove 70 on the push block 7 and the pushing of the push block 7 can ensure that when the sinking triangle 6 corresponding to the starting stitch is in a high position, the sinking triangle 6 corresponding to the returning stitch is also in a high position. Figure 4 Part 4-2; In this embodiment, the sinker triangle also forms a high and low position state of the sinker triangle 6 that is adapted to the corresponding starting and returning stitches when corresponding to other knitting. These will not be described in detail here.

[0033] The difference between this embodiment and embodiment one is that the running path lengths on the two sinker triangles 6 are respectively longer than the corresponding needle start-up and return-up sections, allowing for full control of the sinker plate during either the start-up or return-up section. Therefore, the adjacent ends of the two sinker triangles 6 need to be joined. In this embodiment, the adjacent ends of the two sinker triangles 6 are respectively provided with stepped structures that can fit together. These stepped structures are located on the needle heel running path, ensuring that the joining point does not produce a seam wider than the needle heel. For details, please refer to... Figure 5 and Figure 6 .

[0034] In this embodiment, the front end of the sinker plate 6 in the return section of the knitting needle acts on the arc between the loop and the loop at the bobbin opening, which also solves the problem of single filament return needles in loop-joining needles. However, when the sinker plate 6 is working in its entirety, the effect of the sinker plate acting on the arc between the loop and the loop is better when the knitting needle starts. However, when the sinker plate 6 is working in its entirety in the return section, it is easy to cause the fabric density to be too tight, which will affect the transfer and joining of loops during the transfer knitting. When the fabric density is too tight, it is easy to cause the yarn to break during the transfer, resulting in holes in the fabric. Example

[0035] This embodiment also follows the example of... Figure 1 , 2 The process is performed on the horizontal knitting machine and triangular base plate shown. For example... Figure 5 As shown, four sinking triangles 6 are provided on the sinking triangle base plate 5 corresponding to the position of each knitting needle movement cycle, and are slidably connected to the sinking triangle base plate 5. Figure 5The images show the front and top views of the four sinker triangles 6. The four sinker triangles 6 are arranged in pairs, with the two sinker triangles 6 in each pair positioned left and right. The two pairs of sinker triangles are symmetrically positioned with respect to the center line of the knitting area formed by several knitting triangles on the base plate, and respectively correspond to the starting and returning stitches of the loop knitting. The two sinker triangles 6 in the pair corresponding to the returning stitches correspond to the first returning stitch and the second returning stitch, respectively.

[0036] Similarly, each settlement triangle 6 consists of a settlement base plate 60, a starting pin triangle 61, and a returning pin triangle 62. The returning pin triangle 62 and the starting pin triangle 61 are arranged opposite each other, and the running path B of the settlement plate heel is formed between the returning pin triangle 62 and the starting pin triangle 61 by the pushing slope 611, the lower limit plane 612, the pushing slope 621, and the upper limit plane 622.

[0037] The running path lengths on the two sets of sinker triangles 6 are respectively longer than the corresponding needle start-up and return-up lengths, allowing for full-length control of the sinker plate during either the start-up or return-up section. Therefore, the adjacent ends of two adjacent sets of sinker triangles 6 need to be joined. Simultaneously, the adjacent ends of two sinker triangles 6 within each set also need to be joined. The adjacent ends of two sinker triangles 6 within each set and the adjacent ends of two sinker triangles 6 adjacent to each set are respectively equipped with stepped structures that can fit together. The structure after the four sinker triangles 6 are joined is as follows: Figure 6 , Figure 6 Part 6-1 is the front view after the four settlement triangles 6 are joined together, and part 6-2 is the top view after the four settlement triangles 6 are joined together. The stepped structure in the settlement triangles makes the running path B of the settlement plate needle heel a continuous path. There will be no gaps in the running path due to gaps between adjacent settlement triangles 6, which will not affect the continuous sliding of the settlement plate needle heel and make the needle heel run smoothly.

[0038] The four settlement triangles 6 on the settlement triangle base plate 5 are moved up and down by a pushing assembly, which also includes a sliding pin 63 and a push block 7, as shown in the image. Figure 7 As shown in section 7-2, the push block 7 is provided with three grooves 70 whose width is adapted to the sliding pin 63 and which contain inclined guide surfaces. After the sliding pin 63 passes through the settlement triangular base plate 5, it is slidably placed in the groove 70. Pushing the push block 7, the sliding pin 63 slides along the inclined guide surface in the groove 70, thereby pushing the settlement triangle 6 to move upward to a high position or downward to a low position along the settlement triangular base plate 5.

[0039] The sliding pins 63 of the two outermost settlement triangles 6 slide in the two outermost sliding grooves 70 respectively, while the sliding pins 63 of the two middle settlement triangles slide in the middle sliding grooves 70.

[0040] During the shift stitch knitting process, in the cast-on section, the corresponding set of sinker triangles 6 needs to be active, i.e., in a high position. In the return stitch section, the sinker triangles 6 corresponding to the first return stitch section are in a low position due to the setting of the slide groove 70 and the pushing of the push block 7, while the sinker triangles 6 corresponding to the second return stitch section are in a high position. At this time, the positions of the sinker triangles 6 and the slide block 7 are as follows: Figure 7 As shown, in this state, the sinker on the starting section of the knitting needle is in the working position, and its active end can always act on the bobbin loop and the arc, resulting in the best effect. During the loop transfer, the sinker is in the non-working position before the end of the first return stitch of the looper needle, and its active end does not act on the bobbin loop and the arc between the loops. When the second return stitch of the looper needle begins, the sinker returns to the working position and can act on the bobbin loop and the arc between the loops again, as shown. Figure 7 As shown in section 7-1.

[0041] In this embodiment, the sinker triangle, when corresponding to other knitting operations, forms a high or low position state 6 of the sinker triangle by pushing the push block 7, which is adapted to the corresponding cast-on and return stitch sections. Figure 8-12 As shown, this is to accommodate different weaving needs, which will not be elaborated on here.

[0042] Combination Figure 13 As shown, in this embodiment, in order to guide the vertical movement of the settlement triangle 6 on the settlement triangle base plate 5, a strip hole 50 is provided on the settlement triangle base plate 5 corresponding to the sliding pin 63. The sliding pin 63 passes through the strip hole 50 and is slidably connected to the strip hole 50. A guide pin 64 is also provided in the vertical direction where the sliding pin 63 is located. The guide pin 64 is slidably connected in the strip hole 50. The guide pin 64 and the sliding pin 63 together guide the vertical movement of the settlement triangle 6 and prevent the settlement triangle 6 from rotating during the vertical movement.

[0043] In this embodiment, the four sinker triangles 6, by pushing the pusher block 7, can always act on the arc between the bobbin loop and the loop by pushing the sinker plate at the starting section of the knitting needle, achieving the best effect. At the same time, it can completely satisfy the requirement that the front end of the sinker plate does not act on the bobbin loop and the arc before the end of the first back stitch stage of the loop-connecting needle during the loop transfer. When the second back stitch stage of the loop-connecting needle begins, the sinker plate can act on the bobbin loop and the arc between the loop again. This can effectively solve the shortcomings of Embodiment 1 and Embodiment 2, solving the monofilament problem and maintaining a better fabric density.

[0044] The technical solutions of the present invention are not limited to the above embodiments. All technical solutions obtained by equivalent substitution fall within the scope of protection claimed by the present invention.
