A transmission structure for a large circular machine with smooth operation

Abstract

This application provides a stable transmission structure for a large circular knitting machine, including the machine body and a transmission structure. The transmission structure includes a lint removal structure. A second motor-driven rack and rotating gear disc in the lint removal structure drive a suction pipe that swings, allowing the suction pipe to cover the tooth grooves of the first and second synchronous belts, as well as the gap between the gear pulley and the driven pulley. This effectively removes lint and environmental dust generated by yarn friction and breakage in the textile workshop, preventing lint from embedding in the synchronous belt and pulley tooth grooves, thus avoiding tooth skipping and slippage. It also prevents fabric defects such as horizontal stripes and missed stitches caused by fluctuations in spindle speed, ensuring transmission accuracy and the finished fabric yield. Simultaneously, the lint removal structure reduces dust accumulation at transmission connection points, reducing frictional resistance between components, decreasing motor energy consumption, slowing the wear rate of bearings, bushings, and other vulnerable parts, extending the service life of transmission components, and reducing equipment maintenance frequency and costs.

Description

Technical Field

[0001] This application relates to the field of large circular knitting machine technology, and in particular to a transmission structure for a large circular knitting machine that operates smoothly. Background Technology

[0002] Circular knitting machines are core equipment in the textile industry for producing knitted fabrics. Their transmission structure, as a key carrier of power transmission, directly determines the stability of the equipment's operation and the quality of the finished fabric. Currently, most commercial circular knitting machines on the market, to meet the needs of convenient equipment maintenance, reduced manufacturing costs, and prevention of overheating of transmission components, generally adopt a semi-open design for their transmission structure. This means that core transmission components such as the motor, main shaft, synchronous belt, and pulleys are not completely enclosed, but only basic protection is achieved through simple protective covers, allowing the transmission system to be directly or indirectly connected to the textile workshop environment. In textile production, yarn generates a large amount of lightweight fluff due to fiber friction and breakage. Furthermore, air circulation in the workshop causes environmental dust to spread, resulting in the large circular knitting machine's transmission structure being in a high-dust, high-fluff environment for a long time. To ensure the accuracy and stability of power transmission, the large circular knitting machine's transmission system usually uses synchronous belt drive. The synchronous belt has convex teeth on its surface that match the pulley's tooth grooves, but the groove structure between its convex teeth happens to become a carrier for fluff accumulation and entanglement. The existing problems are as follows: Flying fibers can easily get embedded in the grooves between the teeth of the timing belt and the tooth grooves of the pulley. As the equipment runs, they are continuously compacted and wrapped, gradually destroying the meshing accuracy between the timing belt and the pulley, causing tooth skipping and slippage during transmission, resulting in fluctuations in the spindle speed, which directly affects the uniform rotation of the syringe, and in turn causes defects such as horizontal stripes and missed needles in the fabric, reducing the finished product qualification rate. Furthermore, dust tends to accumulate at the connection points of the transmission structure, forming a hard layer of dirt. This layer of dirt increases the frictional resistance between components, which not only increases motor energy consumption but also accelerates the wear rate of vulnerable parts such as bearings and bushings, shortens the service life of transmission components, and increases the frequency and cost of equipment maintenance.

A lint removal structure is fixedly mounted on the right side of the top of the mounting plate.

[0005] In one embodiment, the dust-collecting end of the lint-removing structure is aligned with the first synchronous belt tooth groove, the second synchronous belt tooth groove, and the tooth gap between the speed reducer pulley and the driven pulley.

[0006] In one embodiment, the connecting plate is made of a shock-absorbing material, and a rubber buffer pad is provided at the connection between the connecting plate and the first motor.

[0007] In one embodiment, the lint removal structure includes a support plate, which is fixedly installed on the top right side of the mounting plate. A second motor is fixedly installed at the right rear end of the support plate. A turntable is fixedly installed through the output end of the second motor on the right side of the support plate. A crank connecting rod is fixedly installed at the eccentric position of the turntable. A guide block is fixedly installed at the left front end of the support plate. A slider is hinged to the end of the crank connecting rod away from the turntable. The slider is slidably disposed in the guide groove of the guide block and is limited. A rack is fixedly installed at the front end of the slider. The front end of the rack meshes with a rotating gear disk, the bottom of the rotating gear disk is provided with a rotating shaft, and is rotatably mounted on the top of the mounting plate through the rotating shaft. A connecting column is fixedly provided on the top of the rotating gear disk, and a collection structure is fixedly installed on the top of the connecting column. The dust suction end of the collection structure is aligned with the first synchronous belt tooth groove, the second synchronous belt tooth groove, and the tooth gap between the reduction belt pulley and the driven pulley.

[0008] In one embodiment, the collecting structure includes a lower bucket, the bottom of which is coaxially fixedly mounted to the top of a connecting column. An upper bucket is detachably and sealedly mounted on the top of the lower bucket, and the two cooperate to form a sealed cavity. A connecting nozzle is integrally formed on the top of the upper bucket, and the connecting nozzle communicates with the cavity. A feed nozzle is sealed and penetrated on the outside of the lower bucket, and a dust suction pipe is connected to the feed inlet of the feed nozzle. Both the feed nozzle and the dust suction pipe communicate with the cavity. The dust suction pipe, driven by a rotating gear disc, can be aligned with the first synchronous belt tooth groove, the second synchronous belt tooth groove, and the tooth gap between the reduction belt pulley and the driven pulley.

[0009] In one embodiment, the rotating toothed disc can rotate alternately clockwise and counterclockwise under the drive of the rack, and the connecting column synchronously drives the collecting structure to swing around the rotating shaft, so that the suction port of the dust suction pipe circulates across the first synchronous belt tooth groove, the second synchronous belt tooth groove, and the tooth gap between the speed reduction pulley and the driven pulley, thereby achieving full coverage suction of flying fluff and dust.

[0010] In one embodiment, the lower bucket has an integrally formed docking ring at the top, and the inner sidewall of the docking ring is provided with a sealing groove; the upper bucket has an integrally formed mounting ring at the bottom that is adapted to the docking ring, and the mounting ring can be nested in the sealing groove of the docking ring to form a preliminary seal.

[0011] In one embodiment, the suction pipe is a metal corrugated pipe, which can be manually bent to achieve arbitrary angle adjustment to fit the gap between the synchronous belt tooth groove and the pulley.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following: This application discloses a transmission structure for a large circular knitting machine that operates smoothly. By incorporating a lint removal structure, the suction pipe is driven by a rack and a rotating gear plate driven by a second motor. This allows the suction pipe to cover the tooth grooves of the first and second synchronous belts, as well as the gap between the gear teeth of the reduction belt pulley and the driven pulley. This effectively removes lint and environmental dust generated in the textile workshop due to yarn friction and breakage. It also prevents lint from embedding in the synchronous belt and pulley tooth grooves, thus avoiding tooth skipping and slippage. Furthermore, it prevents fabric defects such as horizontal stripes and missed needles caused by fluctuations in the spindle speed, ensuring transmission accuracy and the pass rate of finished fabric products. Meanwhile, the lint removal structure can reduce the accumulation of dust in the transmission connection parts to form a hard dirt layer, thereby reducing the frictional resistance between components, reducing motor energy consumption, slowing down the wear rate of vulnerable parts such as bearings and bushings, extending the service life of transmission components, and reducing the frequency and cost of equipment maintenance. In addition, the connecting plate made of Mn-Cu damping alloy, combined with the rubber buffer pad, can effectively absorb the vibration of the first motor during operation, further improving the operational stability of the transmission structure.

[0021] Reference Figure 1 A transmission structure for a large circular knitting machine that operates smoothly includes a large circular knitting machine body 1. The large circular knitting machine body 1 is a known technology and will not be described in detail. The main body 1 of the large circular knitting machine is equipped with a large disc gear and a transmission structure 20. The transmission structure 20 serves as the core component for power transmission, transmitting stable and continuous power to the large disc gear of the main body 1 of the large circular knitting machine. Furthermore, the stability of power transmission is ensured by the inclusion of a lint removal structure 22.

[0022] In one embodiment, reference is made to Figures 2-3 The transmission structure 20 includes a base frame 201, which is fixedly connected to the machine base of the large circular machine body 1. A mounting plate 202 is provided at the bottom of the base frame 201, a connecting plate 203 is fixedly installed at the tail end of the mounting plate 202, and an extension plate 204 is fixedly installed at the front end of the mounting plate 202. The base frame 201 is used to provide an installation reference for the transmission structure 20 as a whole. The mounting plate 202 serves as an intermediate installation platform, supporting the connecting plate 203 and the extension plate 204. The connecting plate 203 is used to fix the first motor 205, and the extension plate 204 is used to provide installation positions for the gearbox 208 and the reduction pulley 209.

[0023] A first motor 205 is fixedly installed at the tail end of the connecting plate 203. A first synchronous belt 206 is sleeved on the outer pulley of the output end of the first motor 205. The first motor 205 serves as a power source, providing the initial power required for transmission, and transmits the power to the first synchronous belt 206 through the output pulley.

[0024] The first synchronous belt 206 is connected to a drive pulley 207 at the output end of the first motor 205. The drive pulley 207 is used to input the power transmitted by the first synchronous belt 206 into the reduction gearbox 208 and transmit the power to the reduction gearbox 208.

[0025] The drive pulley 207 is coaxially fixed to the input end of the gearbox 208. The gearbox 208 is fixed to the top of the extension plate 204 by a bracket. The gearbox 208 reduces the power input by the drive pulley 207 and increases the torque, adjusting the speed and torque to match the running requirements of the large disc gear of the main body of the large circular machine.

[0026] A reduction pulley 209 is connected to the bottom output end of the reduction gearbox 208. The top of the reduction pulley 209 is fixedly connected to the bottom output end of the reduction gearbox 208, and its bottom is rotatably mounted on the top of the extension plate 204. A second synchronous belt 210 is sleeved on its outer side. A driven pulley 211 is connected to the end of the second synchronous belt 210 away from the reduction pulley 209. The reduction pulley 209 is used to receive the power output by the reduction gearbox 208 and transmit it to the driven pulley 211 through the second synchronous belt 210. Driven pulley 211 is used to transmit power from second synchronous belt 210 to output gear 212, and is an intermediate conversion component for power transmission.

[0027] Driven pulley 211 is rotatably mounted on the top of mounting plate 202, and output gear 212 is fixedly mounted on the top of driven pulley 211. Output gear 212 meshes with the large disc gear of the large circular knitting machine body 1. The output gear 212 meshes with the large disc gear of the large circular knitting machine body 1, and ultimately transmits the power of the transmission structure to the large circular knitting machine body 1 to drive its operation.

[0028] A transmission rod 213 is fixedly connected to the top of the output gear 212, which connects the output gear 212 and the aluminum disk 214 to transmit rotational power to the aluminum disk. An aluminum disc 214 is fixedly installed at the top of the transmission rod 213. The aluminum disc 214 can rotate synchronously with the transmission rod 213 to feed the yarn required for weaving into the cylinder in the main body 1 of the circular knitting machine.

[0029] A lint removal structure 22 is fixedly installed on the top right side of the mounting plate 202. The lint removal structure 22 uses negative pressure adsorption to accurately remove flying lint and dust from the synchronous belt tooth groove and pulley gap, thus preventing impurities from affecting the transmission accuracy.

[0030] Among them, the dust suction end of the lint removal structure 22 is aligned with the tooth groove of the first synchronous belt 206, the tooth groove of the second synchronous belt 210, and the tooth gap between the reduction belt pulley 209 and the driven pulley 211. When the synchronous belt tooth groove meshes with the pulley, the gaps between the teeth can easily trap yarn lint generated during weaving. Dust and fiber debris can also accumulate in the gaps between the pulley teeth due to long-term transmission. If not cleaned in time, these impurities can cause the synchronous belt and pulley to mesh loosely, resulting in transmission slippage. This can lead to fluctuations in power transmission, affecting the stability of the meshing between the output gear 212 and the large disc gear of the main body 1 of the circular knitting machine. Ultimately, this can cause problems such as uneven density and defects in the woven fabric. At the same time, the accumulation of impurities can also accelerate the wear of the synchronous belt tooth surface and the pulley teeth, shortening the service life of the transmission components.

[0031] By precisely targeting these areas with the suction end, impurities can be removed in real time. This ensures the meshing accuracy of the synchronous belt and pulley, maintains the smoothness of power transmission, reduces component wear and extends service life, and prevents flying lint from falling onto the cylinder of the circular knitting machine or the surface of the fabric, thereby further improving the pass rate of woven products.

[0032] In this embodiment, the connecting plate 203 is made of Mn-Cu damping alloy. Mn-Cu damping alloy has both a certain installation strength and good shock absorption and damping performance. While ensuring the stability of the first motor 205, it can absorb part of the vibration energy of the first motor 205 during operation through its own material properties, thereby improving the stability of power transmission. A rubber buffer pad is provided at the connection between the connecting plate 203 and the first motor 205. The rubber buffer pad can directly absorb the high-frequency vibration output by the first motor 205 by utilizing its elastic deformation characteristics. Combined with the connecting plate 203 made of Mn-Cu damping alloy, it can greatly improve the stability of power transmission and ensure the smoothness of power transmission of the entire transmission structure.

[0033] During operation, the first motor 205 serves as the power source, driving the first synchronous belt 206 via the output pulley. The first synchronous belt 206 connects to the driving pulley 207, transmitting power to the reduction gearbox 208 for speed and torque matching. The matched power is then transmitted to the driven pulley 211 via the reduction pulley 209 and the second synchronous belt 210. The driven pulley 211 then drives the top output gear 212 to rotate. The output gear 212 meshes with the large disc gear of the main body 1 of the circular knitting machine to complete the power output. The transmission rod 213 at the top of the output gear 212 is used to install the yarn feeding aluminum disc 214. The yarn feeding aluminum disc 214 rotates synchronously with the transmission rod 213 to feed the yarn required for weaving into the needle cylinder in the main body 1 of the circular knitting machine. In addition, the lint removal structure 22 can accurately remove flying lint and dust from the synchronous belt tooth groove and pulley gap, ensuring the stability of power transmission.

[0034] In one embodiment, reference is made to Figure 4The lint removal structure 22 includes a support plate 221, which is fixedly installed on the top right side of the mounting plate 202. The support plate 221 serves as the overall installation base for the lint removal structure 22 and plays the role of installation and connection.

[0035] A second motor 222 is fixedly installed at the right end of the support plate 221. The second motor 222 serves as the power source for the lint removal structure 22, providing driving force to rotate the turntable 223.

[0036] The output end of the second motor 222 passes through the right side of the support plate 221 and is fixedly installed with a turntable 223. The turntable 223 can rotate synchronously with the second motor 222. A crank connecting rod 224 is installed at its eccentric position. The continuous rotational motion of the second motor 222 is converted into the periodic push-pull motion of the crank connecting rod 224 through its own rotation.

[0037] A crank connecting rod 224 is fixedly installed at the eccentric position of the turntable 223, and a guide block 225 is fixedly installed at the front left side of the support plate 221. A slider 226 is hinged to the end of the crank connecting rod 224 away from the turntable 223. The crank connecting rod 224 is used to convert the rotational motion of the turntable 223 into the reciprocating linear motion of the slider 226.

[0038] The slider 226 is slidably disposed in the guide groove of the guide block 225 and is limited to restrict the movement trajectory of the slider 226, ensuring that the slider can only make linear reciprocating motion along the guide groove, and avoiding movement deviation from affecting the meshing accuracy of the subsequent rack.

[0039] A rack 227 is fixedly installed at the front end of the slider 226. When the rack 227 moves back and forth in a linear motion with the slider 226, it drives the rotating gear disk 228 to rotate alternately clockwise and counterclockwise through inter-tooth meshing, realizing the secondary conversion from linear motion to rotational motion.

[0040] The front end of the rack 227 meshes with a rotating gear disk 228. Driven by the rack, it rotates in both directions. At the same time, the rotational motion is transmitted to the collecting structure 231 through the connecting post 230 at the top, thereby achieving the oscillating effect of the collecting structure 231.

[0041] The bottom of the rotating gear disk 228 is provided with a rotating shaft 229, which is rotatably mounted on the top of the mounting plate 202. The rotating shaft 229 is used to provide a stable rotation fulcrum for the rotating gear disk 228, ensuring the stability of the rotating gear disk 228 when it rotates.

[0042] A connecting post 230 is fixedly installed at the top of the rotating toothed disk 228. The connecting post 230 is used to connect the rotating toothed disk 228 and the collecting structure 231, and transmits the rotational motion of the rotating toothed disk 228 to the collecting structure 231, causing the collecting structure 231 to swing synchronously, so that the dust suction end can cover multiple lint removal areas.

[0043] A collection structure 231 is fixedly installed at the top of the connecting column 230. The dust suction end of the collection structure 231 is aligned with the tooth groove of the first synchronous belt 206, the tooth groove of the second synchronous belt 210, and the tooth gap between the reduction belt pulley 209 and the driven pulley 211. The collection structure 231 removes the flying fluff and dust in the above parts through the dust suction function, so as to avoid impurities affecting the transmission accuracy.

[0044] In one embodiment, reference is made to Figure 5 The collecting structure 231 includes a lower bucket 2311, the bottom of which is coaxially fixedly installed on the top of the connecting column 230, and an upper bucket 2313 is detachably and sealedly installed on the top of the lower bucket 2311. The two work together to form a sealed cavity. The two form a detachable sealed cavity, which can provide space for the temporary storage of flying fluff and dust. The detachable design makes it easy to clean the impurities collected in the cavity later. The installation method of fixing the lower bucket 2311 coaxially to the top of the connecting column 230 can ensure that there is no radial offset when the lower bucket 2311 rotates synchronously with the connecting column 230.

[0045] The top of the upper bucket 2313 is integrally formed with a docking nozzle 2315, which is connected to the cavity and is mainly used to connect to an external negative pressure device. The negative pressure device forms a continuous suction in the sealed cavity, providing a power source for flying fluff and dust to enter the cavity from the suction pipe 2317.

[0046] The lower bucket 2311 is sealed and has a feed nozzle 2316 through it. The feed inlet of the feed nozzle 2316 is connected to a dust suction pipe 2317. Both the feed nozzle 2316 and the dust suction pipe 2317 are connected to the cavity. The dust suction pipe 2317 can be aligned with the tooth groove of the first synchronous belt 206, the tooth groove of the second synchronous belt 210, and the tooth gap between the reduction belt pulley 209 and the driven pulley 211 under the drive of the rotating toothed disc 228. The feed nozzle 2316 serves as a transfer channel for flying lint and dust to enter the cavity. Its sealed through-hole design prevents the negative pressure inside the cavity from leaking out through the installation gap, ensuring that the suction force is effectively transmitted to the suction pipe 2317. The suction pipe 2317 cleans the tooth grooves of the first synchronous belt 206, the tooth grooves of the second synchronous belt 210, and the tooth gaps between the reduction pulley 209 and the driven pulley 211.

[0047] The rotating toothed disc 228 can rotate alternately clockwise and counterclockwise under the drive of the rack 227. The connecting column 230 synchronously drives the collecting structure 231 to swing around the axis of the rotating shaft 229, so that the suction port of the suction pipe 2317 circulates across the tooth groove of the first synchronous belt 206, the tooth groove of the second synchronous belt 210, and the tooth gap between the speed reduction pulley 209 and the driven pulley 211, so as to achieve full coverage suction of flying fluff and dust.

[0048] The lower bucket 2311 has an integrally formed docking ring 2312 at its top, and the inner wall of the docking ring 2312 is provided with a sealing groove; the upper bucket 2313 has an integrally formed mounting ring 2314 at its bottom that is adapted to the docking ring 2312, and the mounting ring 2314 can be nested in the sealing groove of the docking ring 2312 to form a preliminary seal; the docking ring 2312 and the mounting ring 2314 are connected by threads to achieve detachable fixation and form a sealed cavity; The docking ring 2312 at the top of the lower bucket 2311 and the mounting ring 2314 at the bottom of the upper bucket 2313 are both made in one piece. This avoids the dimensional deviation and strength problems of the spliced ​​structure. The design of the mounting ring 2314 nested into the sealing groove of the docking ring 2312 can quickly achieve precise positioning and initial sealing of the two, thus preventing air leakage. The docking ring 2312 and the mounting ring 2314 are fixed by a threaded connection, which not only further compresses the fitting gap and strengthens the sealing effect, but also allows the lower bucket 2311 and the upper bucket 2313 to be easily separated by disassembling the threads when it is necessary to clean the accumulated fluff and dust in the cavity, thus taking into account the connection stability, sealing reliability and maintenance convenience.

[0049] In this embodiment, the suction pipe 2317 is a metal corrugated pipe, which can be manually bent to achieve arbitrary angle shaping and adjustment to fit the gap between the synchronous belt tooth groove and the pulley; By manually bending and adjusting the angle, it can accurately adapt to the different positions and angles of the tooth grooves of the first synchronous belt 206, the second synchronous belt 210, and the tooth gaps between the reduction belt pulley 209 and the driven pulley 211, ensuring that the dust suction end closely corresponds to the place where impurities accumulate. Its metallic material properties give it strong stability after bending, and it can maintain the set angle without deviation even when the equipment vibrates or the collection structure 231 swings, ensuring long-term dust collection accuracy.

[0050] Working principle: After the first motor 205 starts, it serves as a power source, driving the first synchronous belt 206 to rotate through the output pulley. The first synchronous belt 206 transmits power to the drive pulley 207, which coaxially drives the input end of the reduction gearbox 208. The reduction gearbox 208 reduces the power and increases the torque to match the operating requirements of the large disc gear of the main body 1 of the circular knitting machine. Then, it drives the reduction pulley 209 to rotate through the bottom output end. The reduction pulley 209 then transmits power to the driven pulley 211 through the second synchronous belt 210. The driven pulley 211 drives the top output gear 212 to rotate. The output gear 212 meshes with the large disc gear of the main body 1 of the circular knitting machine, ultimately driving the main body 1 of the circular knitting machine to perform weaving operations. At the same time, the transmission rod 213 at the top of the output gear 212 drives the yarn feeding aluminum disc 214 to rotate synchronously, stably feeding yarn into the cylinder in the main body 1 of the circular knitting machine. During this period, the connecting plate 203 made of Mn-Cu damping alloy, combined with the rubber buffer pad at its connection with the first motor 205, can absorb the vibration of the motor during operation and ensure smooth power transmission. When the lint removal structure 22 is working, the second motor 222 drives the turntable 223 to rotate. The turntable 223 pulls the slider 226 to slide back and forth along the guide groove of the guide block 225 through the crank connecting rod 224 at the eccentric position. The slider 226 drives the rack 227 to move back and forth. The rack 227 meshes and drives the rotating gear disk 228 to rotate clockwise and counterclockwise. The rotating gear disk 228 drives the collection structure 231 to swing around the rotating shaft 229 through the connecting column 230. The function of the swing is to allow the suction pipe 2317 on the collection structure 231 to cover all the impurity accumulation areas in the tooth groove of the first synchronous belt 206, the tooth groove of the second synchronous belt 210, and the gap between the gear teeth of the reduction belt pulley 209 and the driven pulley 211, so as to achieve comprehensive lint removal. It is important to note that the suction pipe 2317 should maintain a certain gap from these target areas to avoid direct suction. If there is direct contact, the negative pressure will exert a pulling force on the synchronous belt and pulley, interfering with the normal transmission rhythm of the synchronous belt and causing fluctuations in power transmission. The reserved gap can effectively remove flying dust through negative pressure, while ensuring the transmission stability of the synchronous belt and pulley, further ensuring the smooth operation of the entire transmission structure.
