Description

Technical Field

[0001] This invention relates to the field of spinning equipment technology, specifically to a drawing frame device based on spinning production. Background Technology

[0002] Drawing is a core pre-treatment process in yarn spinning. Its main function is to combine and draft multiple virgin cotton slivers, eliminating thickness variations in individual slivers, improving overall sliver uniformity, and providing high-quality semi-finished slivers for subsequent spinning. It is a crucial process for ensuring yarn quality and reducing spinning defects. Currently, conventional drawing equipment on the market has a mature structure and can meet basic sliver combining processing needs. However, in actual large-scale production, there are still core structural defects that make it difficult to adapt to the demands of high-precision and high-efficiency spinning production.

[0003] Currently, most traditional drawing machines use a fixed, smooth roller structure. The cotton sliver is directly and tightly wound onto the outer wall of the roller. The large contact area and strong friction between the formed cotton sliver and the roller surface make it difficult for the sliver to separate quickly and smoothly from the roller. In the actual unloading and unloading process, external force is required to forcibly pull and peel it off, which easily causes the formed cotton sliver to be stretched, thinned in some areas, twisted, wrinkled, or even broken. This not only seriously damages the quality of the formed cotton sliver but also leads to a large number of defective products. Summary of the Invention

[0004] The purpose of this invention is to provide a drawing frame device based on spinning production, solving the following technical problems: Currently, the winding rollers of traditional drawing frame devices are mostly integral fixed smooth roller structures. The cotton sliver is directly and tightly wound and adhered to the outer wall of the roller. The formed cotton sliver has a large contact area with the roller surface and strong adhesion friction, which makes it impossible for the cotton sliver to separate from the roller quickly and smoothly after forming. In the actual unloading and unloading process, it can only rely on external force to forcibly pull and peel off, which easily causes the formed cotton sliver to be stretched and lengthened, locally thinned, twisted and wrinkled, or even broken and damaged. This not only seriously damages the forming quality of the cotton sliver but also leads to a large number of defective products.

[0005] The objective of this invention can be achieved through the following technical solutions: A drawing frame based on spinning production includes a base, and a guide frame is fixedly installed at the upper end of the base; Multiple supply cylinders are placed side by side on the upper end of the base. A drawing machine body is provided on one side of the base. An L-shaped bracket is fixedly provided on one side of the guide frame. A bearing slide is slidably provided on the lower end of the L-shaped bracket. A connecting sleeve is symmetrically slidably provided on the lower end of the bearing slide. An annular worm gear is rotatably provided inside the connecting sleeve. A worm is meshed on one side of one of the annular worm gears. Both sides of the annular worm gear are provided with slitting components. The slitting components include a semi-circular ring fixedly disposed on one side of the annular worm gear. Multiple sets of first sliding rods are linearly arrayed on the outer surface of the semi-circular ring, and slitting forks are provided at the lower ends of the first sliding rods. A winding roller is rotatably mounted on one side of the guide frame, and the winding roller is positioned between the two slitting assemblies.

[0006] As a further embodiment of the present invention: grooves are provided at both the upper and lower ends of one side of one of the annular worm gears; The other annular worm gear has tenons that fit the groove at both the upper and lower ends of one side.

[0007] As a further aspect of the present invention: the upper end of the first sliding rod extends to the upper end of the semicircular ring and is provided with a first abutting member, and a second spring is sleeved on the outer surface of the first sliding rod and disposed between the outer wall of the semicircular ring and the first abutting member; The inner annular surface of the connecting sleeve is provided with a plurality of first limiting members that are adapted to the first abutting member.

[0008] As a further aspect of the present invention: the opposing surfaces of the first abutting member and the first limiting member are both integrally formed with matching wedge-shaped surfaces.

[0009] As a further aspect of the present invention: the inside of the winding roller is symmetrically provided with circular seats, and the opposing surfaces of the two circular seats are provided with multiple mounting grooves in an annular array; The bottom of the mounting groove is provided with a second shaft, and the outer surfaces of the two second shafts are fitted with the same connecting plate. The outer surface of the winding roller is provided with multiple sets of through holes, and the upper end of the connecting plate is provided with multiple ejector pins that are adapted to the multiple sets of through holes in a linear array.

[0010] As a further aspect of the present invention: a second bidirectional lead screw is rotatably disposed between the two circular seats, and a hexagonal slide is symmetrically threaded onto the outer surface of the second bidirectional lead screw; The outer surface of the hexagonal slide is provided with multiple telescopic sleeves, and the outer surface of the connecting plate is fitted with multiple second abutting members. The lower ends of the multiple second abutting members are connected to the upper ends of the telescopic sleeves. The inner cavity of the winding roller is provided with multiple second limiting members that are adapted to the second abutting members in a circular array.

[0011] As a further aspect of the present invention: a third spring is sleeved on the outer surface of the second shaft and disposed between the connecting plate and the bottom of the mounting groove.

[0012] As a further aspect of the present invention: a first bidirectional lead screw is rotatably provided at the lower end of the bearing slide, and a first slider is symmetrically threaded on the outer surface of the first bidirectional lead screw, and the lower ends of the two first sliders are respectively connected to two connecting sleeves.

[0013] As a further aspect of the present invention: a transverse sliding base is slidably disposed at the upper end of the guide bar frame, and a traction frame is slidably mounted on the top of the transverse sliding base.

[0014] As a further aspect of the present invention: the traction frame includes a rectangular seat slidably disposed on the upper end of a transverse sliding base, a first clamping plate disposed in the inner cavity of the rectangular seat, a first shaft slidably disposed at the upper end of the rectangular seat extending into the inner cavity, and a second clamping plate disposed at the lower end of the first shaft; A first spring is sleeved on the outer surface of the first shaft and disposed between the inner side wall of the rectangular seat and the second clamping plate.

[0015] The beneficial effects of this invention are: (1) The present invention is equipped with an openable worm gear linkage dynamic slitting mechanism. The worm gear rotation drives the slitting branch to open and close repeatedly, replacing the traditional static fixed slitting structure. It can achieve dynamic and uniform bundling and regularization of multiple cotton slivers, effectively avoiding the problems of stacking, offsetting and sticking during cotton sliver transportation, and greatly improving the uniformity of cotton sliver bundling and processing accuracy. (2) The present invention adopts a retractable pin-type winding roller structure. During the winding operation, the pin protrusion supports the cotton strip forming, so that the cotton strip does not directly adhere to the outer wall of the roller. This completely solves the problem of the cotton strip being too tightly adhered and having high friction, making it impossible to separate quickly. It also eliminates defects such as cotton strip deformation, breakage, and uneven thickness caused by unloading and pulling, and significantly improves the quality of finished cotton strips. (3) The present invention is equipped with a sliding traction mechanism that can be precisely moved, which can automatically align and clamp the cotton sliver end to complete the smooth traction and docking, effectively avoid the cross-entanglement of new and old cotton slivers, simplify manual jointing operation, reduce the difficulty of operation and the product defect rate, and greatly improve the automation level and continuous production efficiency of the drawing process.

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] Example 1 Please see Figure 1As shown, a drawing frame device based on spinning production includes a base, a guide frame 101 fixedly mounted on the upper end of the base, multiple sliver dividers arranged in a linear array on the upper end of the guide frame 101, and several guide posts mounted on each of the multiple sliver dividers. Multiple supply bins are placed side by side on the upper end of the base for storing raw cotton slivers. The drawing frame device body 102 is mounted on one side of the base.

[0023] During operation, the raw cotton slivers stored in each supply bin are sequentially passed out, and after being sorted and bundled by the corresponding sliver divider and guide post, they are uniformly transported to the main body 102 of the drawing equipment to complete the sliver joining, drafting, and forming operations, realizing the processing of multiple raw cotton slivers. The main body 102 of the drawing equipment adopts the existing mature drawing and drafting structure, which is a conventional technology in this field, and its specific structure and working process will not be described in detail here.

[0024] Preferably, please refer to Figure 1 As shown, a transverse sliding base 103 is slidably mounted on the upper end of the guide frame 101 along the direction of the cotton sliver conveying. The transverse sliding base 103 can be precisely moved to the original conveying channel corresponding to the point before the cotton sliver breaks, positioning the traction structure between two adjacent guide posts to prevent cross-entanglement between new and old cotton slivers during conveying. A traction frame is slidably mounted on the top of the transverse sliding base 103 along the length of the sliver divider. The traction frame can be adjusted forward and backward along the conveying direction. The traction frame can stably clamp the new cotton sliver thread end after the supply bucket is replaced and smoothly pull and convey the thread end to the connecting mechanism for cotton sliver splicing at the rear, facilitating quick splicing of new and old cotton slivers by the operator. The sliding mechanism of the transverse sliding base 103 on the guide frame 101 can be driven by a screw and slider mechanism. The sliding mechanism of the traction frame on the transverse sliding base 103 can also be driven by a screw and slider mechanism. The transverse sliding base 103 and the traction frame are respectively equipped with a screw transmission pair and a sliding slider. The slider is driven to slide linearly along the guide rail by the rotation of the screw, thereby realizing the transverse sliding base 103 transversely moving on the guide frame 101 and the traction frame adjusting back and forth on the transverse sliding base 103.

[0025] Preferably, please refer to Figure 2 As shown, the traction frame includes a rectangular seat 104 slidably disposed on the upper end of a transverse sliding base 103. A first clamping plate 105 is disposed in the inner cavity of the rectangular seat 104. A first shaft 106 is slidably disposed through the upper end of the rectangular seat 104 into the inner cavity. A pull ring is disposed at the upper end of the first shaft 106 extending to the upper end of the rectangular seat 104. A second clamping plate 107 is disposed at the lower end of the first shaft 106 extending into the inner cavity of the rectangular seat 104. A first spring 108 is sleeved on the outer surface of the first shaft 106. One end of the first spring 108 is connected to the inner side wall of the rectangular seat 104, and the other end is connected to the second clamping plate 107.

[0026] The pull ring causes the second clamping plate 107 to move upward and compress the first spring 108. After the cotton thread end is placed between the first clamping plate 105 and the second clamping plate 107, the pull ring is released. The first spring 108 rebounds and causes the second clamping plate 107 to press down and cooperate with the first clamping plate 105 to clamp the cotton thread. The traction and delivery of the thread end is completed by the sliding of the rectangular seat 104. The traction speed is smooth and there is no instantaneous tension impact, which prevents the cotton thread from being pulled and broken under the clamping state.

[0027] Example 2 Based on Example 1, please refer to Figure 3 , Figure 4 As shown, a connecting assembly is provided on one side of the guide bar frame 101. The connecting assembly includes an L-shaped bracket 201 fixedly mounted on one side of the guide bar frame 101. A bearing slide 202 is slidably mounted on the lower end of the L-shaped bracket 201. A first bidirectional lead screw 203 is rotatably mounted on the lower end of the bearing slide 202. One end of the first bidirectional lead screw 203 is connected to a drive motor. A first slider 204 is symmetrically threaded onto the outer surface of the first bidirectional lead screw 203. A connecting sleeve 205 is fixedly mounted on the lower end of the first slider 204. The connecting sleeve 205 can be semi-circular or rectangular. The two connecting sleeves 205 are joined together to form a complete circle or rectangle. An annular groove is provided on one side of the connecting sleeve 205. An annular worm gear is rotatably engaged inside the annular groove. 207. The annular worm gear 207 has a semi-circular structure. Two annular worm gears 207 are spliced ​​together to form a complete worm gear. One of the connecting sleeves 205 has a worm that meshes with the annular worm gear 207 inside. One end of the worm is connected to a drive motor. A positioning block is provided on one side of the annular worm gear 207. The annular worm gear 207 is positioned by a visual locator or other positioning structure to ensure that the annular worm gear 207 is in its original snap-fit ​​position when the connecting sleeve 205 is separated, or to accurately control the number of rotations of the annular worm gear 207 so that the number of rotations is an integer multiple. The annular worm gear 207 rotates at a relatively slow speed during actual operation, so it can mesh with the worm after fastening.

[0028] Preferably, please refer to Figure 4 As shown, one annular worm gear 207 has grooves on both the upper and lower ends of one side, and the other annular worm gear 207 has tenons 209 on both the upper and lower ends of one side that are adapted to the grooves.

[0029] The first bidirectional lead screw 203 drives the two connecting sleeves 205 to close. The two half-ring worm gears 207 rely on the tenon 209 and the groove to circumferentially lock into a whole worm gear. When the worm gear meshes and drives one half of the worm gear, it can drive the other half to rotate smoothly together through the tenon groove.

[0030] Preferably, please refer to Figure 4 , Figure 5As shown, both sides of the annular worm gear 207 are provided with slitting components. The slitting components include a semi-circular ring 2111 fixedly disposed on one side of the annular worm gear 207. Multiple sets of first sliding rods 2112 are linearly arranged on the outer surface of the semi-circular ring 2111 along the length extension direction of the semi-circular ring 2111, and multiple first sliding rods 2112 in each set are arranged in a ring array with the center of the semi-circular ring 2111.

[0031] The lower end of the first sliding rod 2112 extends to the inner side of the semicircular ring 2111 and is provided with a slit branch 2113. The lower end of the slit branch 2113 is provided with a U-shaped groove. The upper end of the first sliding rod 2112 extends to the upper end of the semicircular ring 2111 and is provided with a first abutment 2114. One side of the first abutment 2114 is integrally formed with a wedge-shaped surface. On the inner annular surface of the connecting sleeve 205, a plurality of first limiting members 2115 adapted to the first abutment 2114 are arranged in annular array. One side of the first limiting member 2115 is integrally formed with a wedge-shaped surface. A second spring 2116 is sleeved on the outer surface of the first sliding rod 2112. One end of the second spring 2116 is connected to the outer wall of the semicircular ring 2111, and the other end is connected to the first abutment 2114. The wedge-shaped surfaces of the first abutment 2114 and the first limiting member 2115 are adapted to each other.

[0032] The annular worm gear 207 drives the semi-circular ring 2111 to rotate continuously. The wedge-shaped surfaces of the first abutting member 2114 and the first limiting member 2115 are continuously pressed together, driving the first sliding rod 2112 to compress the second spring 2116 to slide back and forth, causing the sliding branch member 2113 with the U-shaped groove on the inner side to cyclically gather and disperse to sort the yarn.

[0033] Example 3 Based on Examples 1 and 2, please refer to Figure 6 , Figure 7 As shown, a winding component is rotatably mounted on one side of the guide frame 101. The winding component is positioned between the two slitting components. After the two slitting components are aligned and the yarn is separated and positioned, the winding component winds the yarn. After the winding process is completed, the two slitting components separate from each other, and the wound yarn can be removed from the winding component by external equipment.

[0034] The winding assembly includes a winding roller 301 rotatably mounted on one side of the guide frame 101. The winding roller 301 can be driven to rotate by a geared motor at low speed or by a gear reduction transmission mechanism to achieve uniform rotation.

[0035] The winding roller 301 has symmetrically arranged circular seats 302 inside, which are located in the inner cavity of the winding roller 301. The opposing surfaces of the two circular seats 302 are provided with a plurality of mounting grooves 303 in an annular array. Preferably, in this embodiment, there are six mounting grooves 303. The bottom of each of the multiple mounting grooves 303 is provided with a second shaft 304. The outer surfaces of the two symmetrical second shafts 304 are fitted with the same connecting plate 305. The connecting plate 305 extends along the length of the winding roller 301. The outer surface of the second shaft 304 is fitted with a third spring 306, and the upper end of the third spring 306 is connected to the connecting plate 305, and the lower end is connected to the bottom of the mounting groove 303. The outer surface of the winding roller 301 has a plurality of through holes 307, and the plurality of through holes 307 in each group are arranged in an annular array around the axis of the winding roller 301. The upper end of the connecting plate 305 is provided with a plurality of ejector pins 308 that are adapted to the through holes 307 in a linear array. The connecting plate 305 is pushed by the third spring 306, causing the ejector pin 308 to pass through the through hole 307 and extend out of the winding roller 301 to wind the yarn.

[0036] Preferably, please refer to Figure 7 As shown, a second bidirectional lead screw 309 is rotatably arranged between two circular seats 302. One end of the second bidirectional lead screw 309 is connected to a drive motor. A hexagonal slide block 310 is symmetrically threaded onto the outer surface of the second bidirectional lead screw 309. The two ends of the hexagonal slide block 310 are limited by limiting rods. A plurality of telescopic sleeve rods 311 are arranged in a ring array on the outer surface of the hexagonal slide block 310. The telescopic sleeve rod 311 is composed of two sets of rods that are nested together. They can slide relative to each other but will not detach. A plurality of second abutment members 312 are sleeved on the outer surface of the connecting plate 305. In this embodiment, there are two second abutment members 312, which are adapted to the left and right hexagonal slide blocks 310. The lower end of the second abutment member 312 is connected to the upper end of the telescopic sleeve rod 311. A plurality of second limiting members 313 adapted to the second abutment members 312 are arranged in a ring array in the inner cavity of the winding roller 301. One side of the second abutment 312 is integrally formed with a wedge-shaped surface, and one side of the second limiting member 313 is also integrally formed with a wedge-shaped surface that matches the second abutment 312.

[0037] During the winding operation, the third spring 306 pushes the connecting plate 305 upward, causing the ejector pin 308 to pass through the through hole 307 and protrude from the outer wall of the winding roller 301. The protruding ejector pin 308 serves as a support frame and rotates at a constant speed with the winding roller 301. The yarn is directly wound around the outside of all ejector pins 308 to form a complete cotton sliver. The cotton sliver only contacts the ejector pin 308 and does not adhere to the winding cylinder body. After winding is completed, the motor drives the second bidirectional lead screw 309 to move the hexagonal slide blocks 310 on both sides towards each other. The telescopic sleeve rod 311 pushes the second abutment 312. The second abutment 312 and the inner cavity second limiting member 313 squeeze the connecting plate 305 through the wedge-shaped surfaces that cooperate with each other. The connecting plate 305 moves down along the second shaft 304 and compresses the third spring 306. All the ejector pins 308 retract into the through hole 307 at the same time. All the protruding support points that originally supported the cotton strip disappear. The cotton strip loses its radial limiting support. A gap is formed between the cotton strip and the winding cylinder. At this time, the external equipment can smoothly pull the connected cotton strip from the outside of the winding roller 301.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
