Description

[Technical Field]

[0001] This disclosure relates to an action part structure of a knitting machine comprising a passage space (1) and related components, and more specifically to an action part structure of a knitting machine including a needle wall assembly (2), a cam assembly (3), and a knitting tool (4). [Background technology]

[0002] In typical knitting machines, such as circular or flat knitting machines, the knitting action is driven by a guide butt of knitting tools, which reciprocate along grooves in the guide section of a cam, synchronously moving and interacting with the knitting tools located within the needle wall assembly, resulting in interlacing of yarns to create the fabric.

[0003] Among the many defects caused by the knitting action, taking circular knitting machines as an example, the two major issues that the industry has consistently faced are the adverse effects of high temperatures on the lifespan and precision of related parts, and fabric contamination by residues such as oil stains and lint. WO2020079493A1 explains various types of fabric defects, such as oil stain defects, needle and sinker defects, and contamination by other fibers.

[0004] In TWI303284B, compressed air is powerfully blown through multiple nozzles and directed towards the needle cylinder, needle groove, knitting needle, and cam assembly to achieve dust removal and heat dissipation effects.

[0005] EP2067885B1 discloses a combined needle bed with fluid passages that can remove accumulated dirt and prevent excess lubricant from contaminating the fabric.

[0006] JP2000-8258A discloses that a cover plate is provided on the outside of the cam assembly to cover the periphery, thereby preventing dust from entering the knitting action part from the outside, and a cooling effect is achieved by operating a blower.

[0007] CN108026676B discloses a molding method, apparatus, and system components in which paired knitting tools are placed in a recess in a needle plate assembly that is wider than conventional designs. By utilizing the timing difference between the movements of adjacent knitting tools or by using a material with a very low friction coefficient and self-lubricating properties (e.g., graphite or PTFE) as a separator, self-cleaning and heat dissipation effects can be achieved.

[0008] The aforementioned technologies achieve pollution reduction and heat dissipation effects by adding operating equipment and more complicated production processes, which increases production costs and energy consumption.

[0009] EP3947799B1 discloses a shape design for another portion of the knitting tool, which is designed so that dirt in a groove near the forming zone is pushed out to the inner edge of the needle bed and eliminated, and the height of the knitting tool and the height of the throat plate assembly are equal. JP2022085768A discloses a double sinker structure in which the height of the knitting tool portion is greater than the height of the throat plate assembly portion.

[0010] TWI639742B shows that the extension surface of a conventional needle plate assembly from the front end to the rear end is parallel to a reference bottom surface that functions as a height reference line on the other side. WO2022128297A1 shows a conventional design in which the top and bottom surfaces of the knitting tool section and the cam assembly section are parallel to each other and have the same height at the front and rear ends. EP4095297A1 shows that in a conventional design, the cam assembly section is parallel to the needle plate assembly section and the knitting tool section, forming a passage space section with parallel sides.

[0011] Based on the quality requirements of fabrics, production capacity needs, and the physical characteristics of thermal expansion, the current design of the air passage area is usually about 0.20 mm high. In this narrow space, high temperatures are continuously accumulated due to the inertia of the knitting action.

[0012] CN1974903A shows that the normal gap at the passage space portion is reduced to almost zero, and compressed air is injected into this space to achieve cleaning and cooling effects.

[0013] CN201678816U shows that the lubricating oil holes in the conventional cam guide groove design can also be used as air passages, allowing air to be blown out to achieve a cooling effect on the passage space and related components.

[0014] The technique of injecting compressed air into the passage space mentioned above not only increases energy consumption, but also tends to cause oil stains scattered by the associated parts to be carried onto the fabric.

[0015] JP4454634B2 identifies contact points and surfaces where the inertia of the knitting action generates heat due to friction between the knitting tool area and the needle wall assembly area.

[0016] After the lubricant is released from the cam guide groove, the aforementioned known design causes the front and rear ends of the needle plate assembly to be at the same height, so that the inertia of the weaving action causes the knitting tool to rub parallel to the needle plate surface, or the guide butt segments of the knitting tool to rub perpendicularly against the side angles of the needle plate. This causes the lubricant to be attracted to and bounced back and forth on these surfaces, resulting in continuous accumulation. Also, other contaminants, such as worn fibers, migrate along the knitting tool toward the loop formation zone, resulting in fabric contamination.

[0017] TWI560331B shows that the shape design of the knitting tool can be improved to clarify the path of the lubricant after it is released and to block contaminants moving towards the loop formation zone. [Prior art documents] [Patent documents]

[0019] The present invention relates to a proposed structure for a knitting component based on the aforementioned technology, conventional designs, and the inertia of the knitting operation. This structure improves product quality without requiring additional equipment or complex processing procedures when manufacturing related components. Furthermore, when using a knitting machine to produce fabric, it protects the fabric from contaminants such as oil stains and lint without requiring additional energy-consuming devices, and optimizes heat dissipation performance, thereby reducing waste due to defective products and extending the service life of related components. [Means for solving the problem]

[0020] To achieve the above-mentioned objectives, the present invention provides a weaving operation part structure including a passage space and related components, including a needle plate assembly, a cam assembly, and a knitting tool. The knitting tool is disposed within the needle plate assembly and forms a passage space toward the cam assembly. At least one passage space section is formed by a cam assembly section relative to the needle plate assembly section and the knitting tool section, and these sections are bounded by a front end close to the circumferential section and a rear end distant from the circumferential section. Excluding the cam guide groove section, the knitting tool guide butt segment, and the maximum and minimum height portions of the knitting tool section, the passage space section forms a gradually expanding space with non-parallel sides from the front end to the rear end, with a height difference of 0.06 mm or more.

[0021] In the following embodiments, at least one associated component has a difference in height between the front and rear ends, thereby causing the sides of the passage space region to be non-parallel from the front end to the rear end. [Effects of the Invention]

[0022] In a first embodiment, the present invention combines a needle plate assembly section with a conventional cam assembly section and a conventional knitting tool section to form a passage space section, which increases resistance along the contaminant movement path, making it more difficult for the contaminants to move toward the loop formation zone. Furthermore, this gradually expanding space provides proper airflow guidance and heat dissipation. In a second embodiment, the present invention combines a cam assembly section with a conventional needle plate assembly section and a conventional knitting tool section to form a passage space section, which reduces the obstruction of backflow along the contaminant migration path and facilitates the migration of contaminants downward away from the loop formation zone. Furthermore, this gradually expanding space provides proper airflow guidance and heat dissipation.

[0023] In a third embodiment, the present invention combines a knitting tool section with a conventional needle plate assembly section and a conventional cam assembly section to form a passage space section, which further assists in counterflow along the contaminant migration path and facilitates the contaminant migration outward from the loop formation zone. Furthermore, this gradually expanding space provides proper airflow guidance and heat dissipation.

[0024] In the fourth embodiment, each air passage space is constructed using the inventive knitting element structure of the previous embodiments, so that in addition to the significant self-cleaning effect, these larger gradually expanding spaces provide better airflow guidance and more effective heat dissipation than the previous embodiments.

During the knitting process, when the knitting tool 4 moves from rear to front and its front edge 4A moves away from the front edge 2A of the needle plate assembly or the front edge 2B of another needle plate assembly, the guide butt segment 43 of the knitting tool is relatively close to the front end 331 of the cam guide groove section and relatively far from the rear end 332.

[0026] The first embodiment shown in FIG. 1 shows a passage space section 10 comprised of a needle plate assembly section 20 of the present invention, a conventional cam assembly section 30, and a conventional knitting tool section 40. Here, when the leading edge (4A) of the knitting tool is flush with the leading edge (2A) of the needle plate assembly or the leading edge (2B) of another needle plate assembly, the area range from the leading end (21) to the trailing end (22) of the needle plate assembly portion of the needle plate assembly (2) is defined as the needle plate assembly portion (20). Similarly, the area ranging from the front apex (31) to the rear apex (32) of the cam assembly portion of the cam assembly (3) is defined as the cam assembly portion (30). Furthermore, the area range from the front apex (41) to the rear apex (42) of the knitting tool portion of the knitting tool (4) is defined as the knitting tool portion (40).

[0027] The knitting tool 4 is a knitting needle having two guide butt segments 43, each corresponding to the guide groove sections 33 of the two cams. The knitting tool part 40 is Knitting tool parts Maximum height H4 and Knitting tool parts Including minimum height H40 nothing In the conventional knitting tool portion 40, Knitting tool parts Front end height H41 Knitting tool parts a rear end height H42 equal to the knitting tool guide butt segment 43; Knitting tool parts Maximum height H4, Knitting tool parts Minimum height H40 Department Except for minutes, Knitting tool parts From the anterior apex 41 Knitting tool parts The surface extending to the rear apex 42 remains parallel to the opposing knitting tool section reference line 401 . The cam assembly 3 is configured by connecting a slider 35 to a cam 34 and a cam box 36. The cam assembly portion formed by the two cams 34 of Anterior apex 31 and Cam assembly area The rear apex 32 is a needle plate assembly site. of Anterior apex 21 and Needle plate assembly area The cam assembly portion 30 corresponds to the rear apex 22. Cam assembly area Front end height H31 Cam assembly area Equal to rear end height H32, Cam assembly area From the anterior apex 31 Cam assembly area The surface extending to the rear apex 32 remains parallel to the opposing cam assembly portion reference line 301 .

[0028] The needle plate 23 of the needle plate assembly 2 employs an insert structure based on patent TWI639742B, which ensures precise dimensions and a smooth outer surface, eliminating the need for grinding or polishing processes after assembly. Needle plate assembly area The front height H21 is Needle plate assembly area Does not match rear end height H22, Needle plate assembly area From the anterior apex 21 Needle plate assembly area The surface extending to the rear apex 22 is not parallel to the facing needle plate assembly site reference line 201. do not have The height difference shown here is 0.08 mm, and this height difference can be realized by a general manufacturing process (e.g., punch press processing) depending on the shape design of the needle plate 23, or can be realized by a general manufacturing process (e.g., lathe processing) depending on the height difference design of the front reference surface 231 and the rear reference surface 232 of the needle plate.

[0029] In this embodiment, the cam assembly portion 30, in combination with the needle plate assembly portion 20 and the knitting tool portion 40, jointly form the passage space portion 10. However, the passage space portion 10 does not include the cam guide groove region 33, the knitting tool guide heel portion 43, the knitting tool portion maximum height H4, and the knitting tool portion minimum height H40. During knitting action under the above conditions, when the knitting tool leading edge 4A is aligned with the needle plate assembly leading edge 2A, the knitting tool guide butt segment 43 is located relatively close to the cam guide groove rear end 332. where: The front end height H11 of the passage space part Passage space area If the standard height H10 is equal to 0.20 mm, the rear end height H12 of the passage space portion is 0.28 mm. In the passage space portion (10), From the front end 11 of the passage space Passage space area The space is gradually expanding towards the rear end 12 because the two sides are not parallel. of From rear height H12 Passage space area This indicates that the height difference minus the front end height H11 is 0.08 mm.

[0030] This disclosure proposes a component structure for a weaving operation. In this structure, the inclined surface of the needle plate assembly section 20 increases the forward resistance along the contaminant's path of travel, making it difficult for the contaminant to approach the loop formation zone. Furthermore, this structure utilizes inertial friction in the weaving operation to assist the contaminant in retreating toward a lower surface, helping the contaminant move away from the loop formation zone. Furthermore, the pressure difference created by the height difference at both ends of the gradually expanding space section ensures proper airflow guidance and achieves effective heat dissipation.

[0031] The second embodiment shown in FIG. 2 illustrates a passageway section 10 comprised of a cam assembly section 30 of the present invention, a conventional needle plate assembly section 20, and a conventional knitting tool section 40. Here, when the leading edge (4A) of the knitting tool is flush with the leading edge (2A) of the needle plate assembly or the leading edge (2B) of another needle plate assembly, the area ranging from the leading apex (21) to the trailing apex (22) of the needle plate assembly portion of the needle plate assembly (2) is defined as the needle plate assembly portion (20). Similarly, the area ranging from the leading apex (31) to the trailing apex (32) of the cam assembly portion of the cam assembly (3) is defined as the cam assembly portion (30). Furthermore, the area ranging from the leading apex (41) to the trailing apex (42) of the knitting tool portion of the knitting tool (4) is defined as the knitting tool portion (40).

[0032] The knitting tool 4 is a knitting needle having four guide butt segments 43, each corresponding to the guide groove sections 33 of the four cams. The knitting tool part 40 is Knitting tool parts Maximum height H4 and Knitting tool parts Including minimum height H40 nothing In the conventional knitting tool portion 40, Knitting tool parts Front end height H41 Knitting tool parts The guide butt segment 43 is equal to the rear end height H42. Knitting tool parts Maximum height H4, Knitting tool parts Minimum height H40 Department Except for minutes, Knitting tool parts From the anterior apex 41 Knitting tool parts The surface up to the rear apex 42 remains parallel to the opposing knitting tool portion reference line 401 .

[0033] In this needle plate assembly 2, the needle plate 23 adopts a conventional insert structure and needs to be polished after assembly to obtain a uniform outer surface. The front end height H21 of the needle plate assembly portion 20 is Needle plate assembly area Equal to the rear end height H22, Needle plate assembly area From the anterior apex 21 Needle plate assembly areaThe surface up to the rear apex 22 remains parallel to the needle plate assembly site reference line 201 opposite it.

[0034] This cam assembly 3 can be manufactured in accordance with a common manufacturing method, in which the cam 34 is locked to the cam box 36, or the slider 35 is inserted into the cam box slider groove 360 ​​on one side and into the cam slider groove 340 on the other side to lock the cam 34. This makes it easy to adjust and move the entire cam assembly part 30.

[0035] In this embodiment, there is a cam assembly portion 30 consisting of four cams 34, and a front end 31 of the cam assembly portion. Cam assembly area The posterior apex 32 corresponds to the anterior apex 21 and posterior apex 22 of the needle plate assembly site, respectively. In this area, the cam assembly area (30) and the needle plate assembly area (20) are combined to jointly form the passage space area (10). However, the passage space area (10) does not include the cam guide groove area (33), the knitting tool guide heel part (43), the knitting tool part maximum height (H4) and the knitting tool part minimum height (H40). The front end height H31 of the cam assembly part is Cam assembly area Unlike the rear height H32, Cam assembly area From the anterior apex 31 Cam assembly area The surface extending to the rear apex 32 is not parallel to the opposing cam assembly site reference line 301. The height difference disclosed here is 0.10 mm, which is the height difference between the slider and each cam 34. of From front height H351 Slider This is achieved by designing a stepped height difference up to a rear end height of H352, and can be achieved using common manufacturing methods such as powder metallurgy.

[0036] During the knitting operation under the above conditions, when the front edge 4A of the knitting tool coincides with the front edge 2A of the needle plate assembly, the position of the guide butt segment 43 is relatively close to the rear end 332 of the cam guide groove. of If the height H11 of the front end is equal to the standard height H10 of 0.20 mm, Passage space area The height H12 of the rear end is 0.30 mm. of From the front end 11 Passage space area The space towards the rear end 12 gradually widens because both sides are not parallel. of From rear height H12 Passage space area The value obtained by subtracting the front end height H11 is 0.10 mm.

[0037] This disclosure proposes a component structure for knitting operation, in which the stepped height difference of the cam assembly section 30 reduces reverse obstacles along the path of contaminants, preventing them from adhering to and accumulating on the lower cam 34 as they naturally move downward. Furthermore, the pressure difference created by the height difference at both ends of the gradually expanding space section ensures proper airflow guidance and achieves effective heat dissipation.

[0038] The third embodiment shown in FIG. 3 illustrates a passageway space section 10 comprised of a knitting tool section 40 of the present invention, a conventional needle plate assembly section 20, and a conventional cam assembly section 30. Here, when the leading edge (4A) of the knitting tool is flush with the leading edge (2A) of the needle plate assembly (2) or the leading edge (2B) of another needle plate assembly, the area ranging from the leading end (21) of the needle plate assembly portion of the needle plate assembly (2) to the trailing end (22) of the needle plate assembly portion is defined as the needle plate assembly portion (20). Similarly, the area ranging from the leading end (31) of the cam assembly portion of the cam assembly (3) to the trailing end (32) of the cam assembly portion is defined as the cam assembly portion (30). Furthermore, the area ranging from the leading end (41) of the knitting tool portion of the knitting tool (4) to the trailing end (42) of the knitting tool portion is defined as the knitting tool portion (40).

[0039] The knitting tool 4 is designed as a sinker including a guide butt segment 43, which corresponds to the cam guide groove 33. The knitting tool part 40 is Knitting tool parts Maximum height H4 and Knitting tool parts The minimum height H40 is included in the conventional knitting tool portion 40. Knitting tool parts Front end height H41 Knitting tool parts It does not match the rear end height H42, Knitting tool parts From the anterior apex 41 Knitting tool parts The surface extending to the rear apex 42 is not parallel to the opposing knitting tool portion reference line 401. The height difference shown here is 0.06 mm, which can be achieved by a typical manufacturing process (e.g., press processing) depending on the shape design of the knitting tool 4.

[0040] The needle plate assembly 2 is lathe-machined and groove-machined to form the needle plate 23. The front end height H21 of the needle plate assembly portion is Needle plate assembly area Equal to the rear end height H22, Needle plate assembly area From the anterior apex 21 Needle plate assembly area The surface extending to the rear apex 22 remains parallel to the opposing needle plate assembly site reference line 201 .

[0041] The cam assembly 3 has a structure in which the cam 34 is directly fixed to the cam box 36. Cam assembly part 30 The rear apex 32 is a needle plate assembly site. of Anterior apex 21 and Needle plate assembly area The cam assembly portion 30 corresponds to the rear apex 22. Cam assembly area Front height H31 Cam assembly area Equal to rear end height H32, Cam assembly area From the anterior apex 31 Cam assembly area The surface up to the rear apex 32 remains parallel to the opposing cam assembly portion reference line 301 .

[0042] In this embodiment, the cam assembly portion 30, in combination with the needle plate assembly portion 20 and the knitting tool portion 40, jointly form the passage space portion 10. However, the passage space portion 10 does not include the cam guide groove portion 33, the knitting tool guide butt segment 43, the knitting tool portion maximum height H4, and the knitting tool portion minimum height H40. During knitting under the above conditions, when the leading edge 4A of the knitting tool coincides with the leading edge 2A of the needle plate assembly, the position of the guide butt segment 43 is relatively close to the rear end 332 of the cam guide groove. where: If the front end height H11 of the passage space is 0.20 mm, Passage space area If it is equal to the standard height H10, Passage space area rear end high The height H12 is 0.26 mm. In the passage space area, From the front end 11 of the passage space Passage space area The space towards the rear end 12 gradually widens because the two sides are not parallel. of From rear height H12 Passage space area The value obtained by subtracting the front end height H11 is 0.06 mm.

[0043] This disclosure proposes a component structure for a weaving operation. In this structure, the inclined surface of the weaving tool section 40 increases the forward resistance of the contaminant path, making it difficult for the contaminant to approach the loop formation zone. Furthermore, the inertial friction of the weaving operation is used to help the contaminant retreat, directing the contaminant toward a lower surface and facilitating its removal from the loop formation zone. In addition, the pressure difference created by the height difference at both ends of the gradually expanding space section ensures proper airflow guidance and achieves effective heat dissipation.

[0044] In the fourth embodiment shown in FIG. 4, the conventional structure in each of the above-described embodiments is changed to the knitting operation component structure of the present invention, thereby forming each passage space portion 10.

[0045] During the knitting operation under the above conditions, when the knitting tool 4 moves from rear to front and its front edge 4A moves away from the front edge 2A of the needle plate assembly or the front edge 2B of another needle plate assembly, the guide butt segment 43 moves relatively closer to the front end 331 of the cam guide groove, and the knitting tool portion 40 also moves relatively. of If the front end height H11 is equal to the standard height H10 of 0.20 mm, Passage space area The height H12 of the rear end ranges from 0.26 mm to 0.38 mm in different embodiments. Passage space area The space towards the rear end 12 gradually widens because the two sides are not parallel. of From rear height H12 Passage space area The value obtained by subtracting the front end height H11 is in the range of 0.06 mm to 0.18 mm.

[0046] Compared with the three previous embodiments, this disclosure proposes a component structure for knitting operation. In this structure, the inclined surfaces of the needle plate assembly portion 20 and the knitting tool portion 40 optimize the forward resistance of contaminants to the loop formation zone and provide rearward support. The inertial friction during knitting accelerates the removal of contaminants, achieving a self-cleaning effect. Furthermore, combined with the cam assembly portion 30, a gradually expanding space with a larger pressure difference is formed, realizing more pronounced airflow induction and more optimized heat dissipation.
