Description

Technical Field

[0001] The invention relates to the technical field of fabric processing devices, in particular to a special processing device for knitted materials. Background Art

[0002] Knitted fabrics are made by bending yarns into loops and interlacing them with knitting needles. In order to improve their aesthetics, they often need to be dyed. In the past, the traditional dyeing process was to place the knitted fabrics in a dye box for dyeing. However, during dyeing, the dye in the dye box is easy to precipitate and the distribution becomes uneven, resulting in dyeing errors in the knitted fabrics and ultimately causing uneven dyeing problems.

[0003] After searching, in the patent with application number 202410405458.9, a kind of high-efficiency and energy-saving dyeing equipment and process for knitted fabrics is disclosed, wherein the surface of the fabric immersed in the dye is slapped by a cloth-slapping mechanism, so that the fabric is stretched and deformed, so that the dye can be more quickly immersed in the gaps between the fabric yarns, improving the dyeing and coloring effects, and the cloth-slapping mechanism can slide back and forth under the drive of the driving motor, so that different positions of the fabric can be slapped, so that the fabric at different positions can be stretched to different degrees, further improving the dyeing effect of the fabric, and when in use, it drives a row of T-shaped slapping rods to be periodically pressed down by a rotating and movable cam to make the fabric tensile and deformed; However, in actual use, when a row of T-shaped beating rods are pressed down vertically to stretch the fabric, a more difficult problem arises. Due to the downward pressure of the beating rods, the edge of the fabric will be subjected to uneven pulling force, which will cause the edge to curl inward. The occurrence of this edge curling seriously affects the overall deformation state of the fabric during the stretching process. The uniform hole expansion effect originally expected to be achieved through stretching is greatly reduced, making the hole expansion degree of various parts of the fabric uneven and the uniformity poor. This undesirable condition further causes problems in the subsequent dyeing link, because the gaps between the yarns of the fabric are of different widths under the uneven stretching and hole expansion state. When the dye is immersed, it is difficult to penetrate smoothly and evenly into these gaps of varying widths, resulting in the distribution of the dye in the fabric cannot reach the ideal uniform state, which seriously affects the quality and effect of fabric dyeing. For this reason, we propose a special processing device for knitted materials. Summary of the invention

[0005] In some embodiments, the first oblique pressing member is located on both sides of the first straight pressing member, and when the first oblique pressing member is pressed downward, the inclination angle of the first oblique pressing member increases successively from the first straight pressing member at the center to both sides.

[0009] In some embodiments, a cylindrical block is fixed to the top end of the second connecting rod, and a first spring is sleeved on the outside of the second connecting rod, and the first spring is connected between the upper end surface of the limiting plate and the cylindrical block.

[0010] In some embodiments, the telescopic plate includes a first plate body and a second plate body, the first plate body is hinged on the second straight rod portion, the second plate body is hinged on the movable plate, and the first plate body and the second plate body are telescopic.

[0011] In some embodiments, in some embodiments, a groove is formed on one side of the first plate body facing the second plate body, a connecting block is connected to one side of the second plate body facing the first plate body, and a second spring is connected between the end of the connecting block and the groove.

[0012] In some embodiments, the first straight pressing members and the first oblique pressing members are alternately distributed, and each of the first oblique pressing members corresponds to two relatively arranged inclined moving mechanisms.

[0013] In some embodiments, two arc-shaped movable plates are provided on the opposite sides of the first pressure cap, and the two arc-shaped movable plates are arranged along the moving direction of the limiting plate.

[0014] The present invention has at least the following beneficial effects: Improve dyeing uniformity: Through the design of the first oblique pressure piece in the first cloth-beating mechanism with the inclination angle increasing from the center to both sides, and the cooperation of the inclined moving mechanism, the first oblique pressure piece closer to the outside has a greater force on the edge of the knitted fabric, which reduces the inward curling of the edge of the fabric, realizes overall stretching and hole expansion, and thus improves the uniformity of subsequent dyeing. During the entire operation, the second connecting rod on the outside is first subjected to force to drive the first pressing block downward, cleverly achieving the consistency of the depth of each extrusion point, further improving the uniformity of the extrusion and stretching process, ensuring more uniform penetration and adhesion of the dye, and improving the dyeing effect.

[0015] Ensure extrusion uniformity: When the second straight rod tilts outward, one end of the movable plate moves downward to drive the L-shaped pressing piece to deflect inward, squeezing the pressed block to move the first pressing block downward, and simultaneously extending the impact extrusion length on both sides, ensuring the extrusion uniformity on both sides of the fabric.

[0016] Improve the extrusion and stretching effect: the first straight pressing member and the first oblique pressing member are distributed alternately, and through the cooperation of the arc-shaped moving plate, the push plate, the first push block and the movable pressing plate and other structures, the second straight rod part can be switched between tilting outward and inward during the back and forth movement of the pressing plate, which not only improves the extrusion and stretching effect, but also makes the stress distribution inside the fabric more uniform, avoids stress concentration in certain specific parts of the fabric, reduces the possibility of defects such as deformation of the fabric, and improves the quality stability of the product.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 5 As shown, the present invention provides a technical solution: a special processing device for knitted materials, including a dyeing tank 1, on which a pressing plate 2 and a limiting plate 3 are distributed up and down, and the pressing plate 2 and the limiting plate 3 can move back and forth along the length direction of the dyeing tank 1, and the pressing plate 2 can also rotate during the movement. The above-mentioned implementation structure is a prior art and will not be repeated here. It also includes a first cloth-patting mechanism 4 and an inclined moving mechanism 5. The first cloth-patting mechanism 4 vertically penetrates the limiting plate 3, and the first cloth-patting mechanism 4 includes a first straight pressing member 41 and a first oblique pressing member 42. The first oblique pressing member 42 includes a tiltable second straight rod portion 422, and the second straight rod portion 42 2 is provided with a retractable first pressing block 4222 at the bottom end, and the first oblique pressing piece 42 is used to realize oblique extrusion and knocking of the knitted fabric during the dyeing process; the tilting movement mechanism 5 is arranged between the first oblique pressing piece 42 and the limiting plate 3, and the tilting movement mechanism 5 is used to realize the synchronous extension of the first pressing block 4222 when the first oblique pressing piece 42 is pressed down and tilted, the first straight pressing piece 41 is arranged in the middle of the limiting plate 3, and the first oblique pressing piece 42 is provided with a plurality of first oblique pressing pieces 42, and the plurality of first oblique pressing pieces 42 are evenly arranged on both sides of the first straight pressing piece 41. When the first oblique pressing piece 42 is pressed down, the inclination angle of the first oblique pressing piece 42 from the center of the first straight pressing piece 41 to both sides increases successively.

[0021] Among them, see Figure 2-Figure 4As shown, the first oblique pressing member 42 also includes a first straight rod portion 421 that passes through the limiting plate 3, and the second straight rod portion 422 is hinged at the bottom end of the first straight rod portion 421. A first pressure cap 4211 is fixed to the top end of the first straight rod portion 421, and the side wall of the first pressure cap 4211 is connected to the first fixed pressing plate 4212. An empty groove 4221 is provided inside the second straight rod portion 422, and the top end of the first pressure block 4222 is connected to a first connecting rod 4223 in the empty groove 4221. During the rotation of the pressing plate 2, the pressing plate 2 will squeeze the first straight pressing member 41 and the first oblique pressing member 42, so that the two move downward to squeeze the knitted fabric, wherein, after the first fixed pressing plate 4212 is squeezed to the tilting moving mechanism 5, the second straight rod portion 422 can be tilted outward.

[0022] See also Figure 2-Figure 4 As shown, the tilting movement mechanism 5 includes a second connecting rod 51 vertically penetrating the limiting plate 3 and a pressure block 53 connected to the top end of the first connecting rod 4223, the inclined end of the pressure block 53 penetrates the outside of the second straight rod portion 422, the bottom end of the second connecting rod 51 is hinged with a movable plate 56, the upper end surface of the movable plate 56 and the lower end surface of the limiting plate 3 are hinged with a hinge rod 55, a telescopic plate 57 is connected between the end of the movable plate 56 away from the second connecting rod 51 and the second straight rod portion 422, the lower end surface of the movable plate 56 is connected with an L-shaped pressing piece 52 matched with the pressure block 53, and the extrusion end of the L-shaped pressing piece 52 and the pressure surface of the pressure block 53 are both provided with There is an inclined surface, and a third spring 58 is connected between the top of the pressure block 53 and the top of the empty groove 4221. The height of the second connecting rod 51 on the limiting plate 3 increases from the middle to the two sides, so that the inclination of the second straight rod portion 422 from the middle to the outside becomes larger, so that the component force toward the edge of the fabric is greater as it is closer to the outside, so that the edge of the fabric can be reduced from curling inward when it is hit and squeezed, thereby improving the overall stretching and hole expansion effect, and improving the uniformity of subsequent dyeing. A cylindrical block is fixed to the top of the second connecting rod 51, and the outer sleeve of the second connecting rod 51 is provided with a first spring 54, and the first spring 54 is connected between the upper end surface of the limiting plate 3 and the cylindrical block.

[0023] See also Figure 5 As shown, the telescopic plate 57 includes a first plate body 571 and a second plate body 572. The first plate body 571 is hinged on the second straight rod portion 422, and the second plate body 572 is hinged on the movable plate 56. The first plate body 571 and the second plate body 572 are telescopic. A groove 573 is provided on a side of the first plate body 571 facing the second plate body 572, and a connecting block 574 is connected to a side of the second plate body 572 facing the first plate body 571, and a second spring 575 is connected between the end of the connecting block 574 and the groove 573.

[0024] Through the above, in actual use, the knitted fabric can be dyed through the dye solution through the cooperation of the guide roller and the winding roller. When the pressing plate 2 and the limiting plate 3 move along the length direction of the dyeing tank 1 (the pressing plate 2 rotates), the pressing plate 2 squeezes the first straight pressing piece 41 and the first oblique pressing piece 42. The first straight pressing piece 41 in the middle and vertical always moves straight downward to squeeze the middle part of the fabric. After the first oblique pressing pieces 42 on both sides move downward for a period of time, the first fixed pressing plate 4212 on the first pressing cap 4211 presses down the cylindrical block at the top end of the second connecting rod 51. The second connecting rod 51 makes one end of the movable plate 56 hinged to the hinged rod 55 move downward, and the other end of the movable plate 56 moves upward to pull the second straight rod part 422 hinged to the first straight rod part 421 to tilt outward, so that when the fabric is squeezed downward, there is a force squeezing toward the edge to reduce the occurrence of the fabric curling inward; Secondly, when the second straight rod portion 422 tilts outward, the bottom end of the second straight rod portion 422 will gradually be higher than the bottom end of the first straight pressing piece 41, so that the lateral extrusion force becomes smaller. For this reason, in the process of the second straight rod portion 422 tilting outward, the downward movement of one end of the movable plate 56 will drive the L-shaped pressing piece 52 to deflect inward, so that the L-shaped pressing piece 52 squeezes the pressure block 53, and the pressure block 53 will move downward along the length direction of the second straight rod portion 422, so that the first pressure block 4222 connected to the first connecting rod 4223 can be moved downward to synchronously extend the impact extrusion length on both sides to ensure uniform extrusion on both sides of the fabric.

[0025] Among them, in the whole operation mechanism, when the external force is applied, the second connecting rod 51 at the outermost position will be squeezed first. Due to its special position layout, it bears the main pressure impact at the beginning of the system startup. This characteristic of being forced first enables the corresponding first pressing block 4222 to respond quickly and start to move downward immediately, so that the outer inclination is greater than the inner inclination. Under this condition, the design of the outermost second connecting rod 51 being forced first to drive the first pressing block 4222 to move downward can cleverly achieve the consistency of the depth of each squeezing point. Specifically, the larger inclination of the outer side means that a larger displacement is required to ensure the balance with the inner side in the squeezing effect, and the early start of the squeezing action on the outer side just makes up for this gap. The direct advantage brought by this design is that it greatly improves the uniformity of the squeezing and stretching process. When the uniformity of squeezing and stretching is guaranteed, the subsequent dyeing process can be carried out more stably. Because the uniform squeezing and stretching makes the structure of the fabric or material more consistent, the dye can penetrate and adhere more evenly, thereby significantly improving the dyeing effect and ensuring that the final product reaches higher quality standards in terms of color and color fastness.

[0026] Example 2: See Figure 6-Figure 9, which is different from the first embodiment, is that the first straight pressing member 41 and the first oblique pressing member 42 are distributed alternately, and each first oblique pressing member 42 corresponds to two relatively arranged inclined moving mechanisms 5, and the inclined moving mechanism 5 is the above-mentioned structure, which will not be repeated here.

[0027] Two arc-shaped movable plates 42111 are provided on the opposite side of the first pressing cap 4211, and the two arc-shaped movable plates 42111 are arranged along the moving direction of the limiting plate 3. The inner bottom of the first pressing cap 4211 is connected with a movable pressing plate 42112 which can cross the first pressing cap 42111, and the upper end surface of the movable pressing plate 42112 is connected with a first pushing block 42113 opposite to the arc-shaped movable plate 42111, and the inner end of the arc-shaped movable plate 42111 is connected with a push plate 42114, and the opposite sides of the push plate 42114 and the arc-shaped movable plate 42111 are provided with matching extrusion slopes.

[0028] Through the above, when the pressing plate 2 and the limiting plate 3 move along the winding direction of the fabric, at this time, the pressing plate 2 squeezes the arc-shaped movable plate 42111 on one side during the rotation process, and the pushing plate 42114 pushes the first pushing block 42113, so that the movable pressing plate 42112 moves toward one side. At this time, the movable pressing plate 42112 can only squeeze the inclined moving mechanism 5 corresponding to the longer extended end, so that the movable pressing plate 42112 tilts outward or inward; When the pressing plate 2 and the limiting plate 3 move in the opposite direction of the winding direction of the fabric, the pressing plate 2 will squeeze the arc-shaped movable plate 42111 on the other side during the rotation, and the pushing plate 42114 will push the first pushing block 42113, so that the movable pressing plate 42112 moves toward the other side. At this time, the movable pressing plate 42112 can also only squeeze the inclined movable mechanism 5 corresponding to the longer extended end, so that the movable pressing plate 42112 tilts inward or outward. In this way, during the back and forth movement of the pressing plate 2, the second straight rod portion 422 can be switched to tilt outward and inward, so that while the extrusion and stretching effect is improved, the stress distribution inside the fabric is made more uniform. When the second straight rod portion 422 switches to tilt outward and inward, the direction and distribution of the force can be changed to avoid stress concentration on certain specific parts of the fabric, thereby reducing the possibility of defects such as deformation of the fabric and the quality stability of the product.

[0029] The above-mentioned method can also realize the outward extension of the first pressing block 4222 when the second straight rod portion 422 is tilted.

[0030] Example 3: See Figure 10-Figure 14As shown, the present invention provides a technical solution: a special processing device for knitted materials, including a dyeing tank 1, on which a pressing plate 2 and a limiting plate 3 are arranged, which are distributed up and down, and the pressing plate 2 and the limiting plate 3 can move back and forth along the length direction of the dyeing tank 1, and the pressing plate 2 can also rotate during the movement. The above-mentioned implementation structure is a prior art and will not be repeated here. It also includes a second cloth-patting mechanism 6 and a lateral outward pulling mechanism 7. The second cloth-patting mechanism 6 vertically penetrates the limiting plate 3, and the second cloth-patting mechanism 6 includes a second straight pressing member 61 and a second oblique pressing member 62. The second straight pressure piece 61 is located in the middle of the limiting plate 3, and a plurality of second oblique pressure pieces 62 are provided, and the second oblique pressure pieces 62 are located on both sides of the middle second straight pressure piece 61, and the second oblique pressure piece 62 is composed of a fixedly connected straight rod portion and an inclined portion, a second pressure cap 621 is fixed at the top of the straight rod portion, a transverse column 622 is fixed at the bottom end of the inclined portion, and a retractable second pressure block 623 is provided at the end of the transverse column 622, and a transverse outward pulling mechanism 7 is connected to the second oblique pressure piece 62, and is used to drive the second pressure block 623 to move outward when the second oblique pressure piece 62 moves downward.

[0031] The lateral outward pulling mechanism 7 includes a third connecting rod 71 that penetrates the limiting plate 3, a fourth connecting rod 72 is connected to the bottom end of the third connecting rod 71, a connecting strip 73 is vertically fixed to the lower end of the fourth connecting rod 72, the inner end of the connecting strip 73 extends into the inclined portion of the second oblique pressure member 62, a moving groove along the length direction is opened on the outer wall of the inclined portion for the up and down movement of the connecting strip 73, the upper end surface of the inner end of the connecting strip 73 is connected to the fourth spring 74, and a convex strip 75 is fixed to the inner bottom of the transverse column 622. A guide groove is provided along the length of the convex strip 75, and a movable second pushing block 76 is provided on the guide groove. A guide block is fixed to the bottom end of the second pushing block 76, and a fifth spring 78 is connected between the guide block and the end of the guide groove. The lower end surface of the inner end of the connecting strip 73 is connected to a third pressing block 79 through a guide rod, and a fifth connecting rod 77 is connected between the second pushing block 76 and the second pressing block 623. A sixth spring is connected between the straight rod portion of the second oblique pressure member 62 and the limiting plate 3, and the elastic force of the sixth spring is greater than that of the fourth spring 74.

[0032] As mentioned above, during specific use, as the straight rod portion moves down to the lower pressure plate on the second pressure cap 621 to squeeze the third connecting rod 71, the connecting strip 73 moves down, and the third pressure block 79 is used to squeeze the second push block 76, so that the second pressure block 623 connected to the fifth connecting rod 77 moves outward to stretch the fabric laterally outward, thereby improving the stretching effect and thereby improving the subsequent dyeing quality.
