[0021] Compared with the prior art, the beneficial effects of the present invention are: The circular weft knitting machine and the knitting method
[0022] (1) The present invention can effectively solve the problem of over-saturation of winding through the traction winding mechanism. Over-saturation of winding will cause the knitted product to overlap at a relatively thick position, forming a bulge that affects the product quality. At the same time, it is easy for the knitted product to fall off the winding shaft and be rolled into the driving device, causing equipment failure. The second motor drives the winding roller to rotate to wind up the knitted product pulled by the traction roller group. At the same time, the first motor drives the turntable to rotate to adjust the winding position of the winding roller. When the knitted product wound on the winding roller reaches a certain amount, that is, the winding is saturated, the knitted product contacts the movable mounting seat to squeeze the connecting spring group, so that the movable conductive block on the inner side of the movable mounting seat contacts the fixed conductive block to form a path, so that the buzzer sounds to signal the staff to remind them to replace the winding roller, thereby ensuring the uniformity of the winding amount and avoiding the phenomenon of over-saturation of winding.
[0023] (2) The present invention can effectively solve the problem of the protective shell of the existing circular knitting machine located on the outside of the fabric winding assembly through the lubricating dust extraction mechanism. The closed structure only plays a simple safety protection role and has a single function. It is impossible to clean the cotton wool and cotton wool on the fabric. At the same time, it is easy for the cotton wool to block the heat dissipation port during normal heat dissipation, thereby causing the device temperature to be too high and causing the fabric winding assembly to malfunction. The protective shell is moved up and down along the electric slide rail to the required position through the cooperation of the hydraulic cylinder and the electric slide group. Then, the dust extraction port extracts the cotton wool attached to the fabric under the suction action of the air pump and stores it in the dust extraction box. In this way, the collection of cotton wool and cotton wool can be achieved, and the functionality of the protective shell is enriched while avoiding contamination and clogging of the device. In addition, in the process of sucking the cotton wool, the waste heat will be extracted together. The waste heat entering the dust extraction box is filtered by the filter plate and then enters the storage box where the lubricating oil is stored and contacts the heat conduction plate. The heat conduction plate absorbs the waste heat and transfers it to the inside of the lubricating oil through the heat conduction rod, thereby improving the heat dissipation efficiency of the device.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] Please refer to Figures 1-9, the present invention provides a technical solution: a circular weft knitting machine, including a lubrication and dust extraction mechanism 1, an electrical control mechanism 3, a frame 4, a knitting mechanism 5, a driving mechanism 6, a yarn feeding mechanism 7 and a radar fan assembly 8. The driving mechanism 6 is arranged inside the frame 4, and the driving mechanism 6 is used to drive the knitting mechanism 5 and the yarn feeding mechanism 7. The electrical control mechanism 3 includes a control panel, a warning light and a buzzer. The traction and winding mechanism 2 includes a mounting bracket 204. Inside the mounting bracket 204, a traction roller group 209 is arranged, and a winding roller 207 is arranged below the traction roller group 209. A winding detection component 206 is arranged outside the winding roller 207, and the winding detection component 206 is connected to both ends of the winding roller 207 through a limiting member 208. A second motor 205 is arranged on one side of the mounting bracket 204, and the output end of the second motor 205 is fixedly connected to the winding detection component 206. The winding detection component 206 includes a limiting disk 2061, and the inner wall of the limiting disk 2061 contacts both ends of the winding roller 207. A fixed conductive block 2062 is installed inside the top of the limiting disk 2061, and a moving conductive block 2063 is arranged below the fixed conductive block 2062. The fixed conductive block 2062 and the moving conductive block 2063 are arranged opposite to each other. A moving mounting seat 2065 is arranged below the winding roller 207, and the moving mounting seat 2065 is fixedly connected to the inner top of the limiting disk 2061 through a connecting spring group 2064. The moving conductive block 2063 is installed inside the top of the moving mounting seat 2065. During operation, first connect the power supply, operate the control panel to start the device. The driving mechanism 6 drives the yarn feeding mechanism 7 to continuously feed the yarn to be processed to the hook of the knitting mechanism 5 to cooperate with the hook core for knitting. At the same time, the radar fan assembly 8 continuously blows air to prevent floating pollutants from depositing on the device. Then, the knitted product is wound by the traction and winding mechanism 2. The winding operation specifically shows that the second motor 205 drives the winding roller 207 to rotate to wind the knitted product pulled inside the traction roller group 209. When the knitted product wound on the winding roller 207 reaches a certain amount, that is, when the winding is saturated, the knitted product above it contacts and squeezes the moving mounting seat 2065. At the same time, the mounting seat 2065 moves to compress the connecting spring group 2064, so that the moving conductive block 2063 inside the moving mounting seat 2065 contacts the fixed conductive block 2062 to form a circuit. Then, the buzzer connected in series on the circuit will sound to remind the staff to replace the winding roller 207, and thus ensure the uniformity of winding. Immediately afterwards, the staff can detach the limiting member 208 to separate the winding roller 207 from the winding detection component 206, and then the winding roller 207 can be detached from the inside of the winding detection component 206 for replacement.
[0036] The traction and winding mechanism 2 further includes a base 201, and a first motor 202 is installed inside the base 201. The output end of the first motor 202 is connected to the bottom of the turntable 203, and the turntable 203 is fixedly connected to the bottom of the mounting frame 204. In the existing circular weft knitting machine, during the winding process, due to the fixed winding position, the products located at a relatively long distance from the winding assembly are likely to be damaged due to excessive stretching over a long time. When performing the winding operation, the first motor 202 synchronously drives the turntable 203 to rotate and adjust the winding position of the winding roller 207, thereby avoiding the products from being damaged due to the deviation of the winding distance.
[0037] The lubrication and dust extraction mechanism 1 includes a protective housing 101, and there are four groups of protective housings 101. At the same time, air pumps 102 are installed on the inner walls of two corresponding groups of protective housings 101. Above the air pumps 102, there is a dust extraction box 103, and the air inlet end of the air pump 102 is connected to the bottom of the dust extraction box 103 through a pipeline. A filter plate 104 is installed inside the dust extraction box 103, and dust extraction ports 105 are evenly arranged on the inner wall of the dust extraction box 103. During the long-term use of the knitting part in the knitting mechanism 5, it is easy for cotton fluffs to wind and adhere to the hook needles, which will cause the hook needles to jam and affect their normal operation. When it is necessary to clean the knitting mechanism 5, start the air pump 102. Under the suction of the air pump 102, the dust extraction ports 105 will continuously suck the cotton fluffs and other pollutants attached to the hook needles. The cotton fluffs entering the dust extraction box 103 are blocked by the filter plate 104 and temporarily stored inside the device, thereby realizing the cleaning of pollutants.
[0038] The lubricating and dust extraction mechanism 1 further includes a storage tank 106, and the storage tank 106 is arranged below the dust extraction box 103. The storage tank 106 is connected to the exhaust end of the air pump 102 through a pipeline. Oil nozzles 107 are evenly arranged on the inner wall of the storage tank 106, and an automatic pressure relief valve 1011 is fixedly connected to the outer wall of the storage tank 106. At the same time, a pressure gauge 1010 is installed on the automatic pressure relief valve 1011. After dust removal, in order to ensure the smooth operation of the knitting mechanism 5, it is necessary to lubricate the latch needles on the knitting mechanism 5. During operation, the filtered gas enters the storage tank 106, and then the pressure inside the storage tank 106 increases. When the staff observes through the pressure gauge 1010 that the pressure reaches the set value, the valve on the oil nozzle 107 is controlled to open, so that the lubricating oil inside the storage tank 106 can be automatically sprayed onto the knitting part of the knitting mechanism 5 due to the excessive pressure difference inside and outside. Here, it should be noted that the oil spraying duration of the oil nozzle 107 is preferably 2 - 3 seconds. After the oil spraying is completed, there is still a large pressure difference inside and outside the storage tank 106. At this time, the staff can open the automatic pressure relief valve 1011 for pressure relief until the value on the pressure gauge 1010 reaches the set value. In addition, dust extraction ports 105 are evenly opened on the inner wall of the dust extraction box 103. The dust extraction box 103 is detachable, that is, the staff can clean the pollutants by disassembling the inspection plate clamped above it. At the same time, the connection part of the inspection plate is sealed.
[0039] A hydraulic cylinder 10 is arranged below the dust extraction box 103, and the telescopic end of the hydraulic cylinder 10 is fixedly connected to the inner wall of the protective housing 101. An electric sliding group 11 is arranged inside the hydraulic cylinder 10, and an electric slide rail 12 is arranged on one side of the electric sliding group 11. The fixed end of the hydraulic cylinder 10 is installed on the electric sliding group 11 and on the electric slide rail 12 on one side of the electric sliding group 11. A traction and winding mechanism 2 is arranged inside the dust extraction box 103, and the traction and winding mechanism 2 is used for winding the knitted fabric. When the staff needs to perform dust removal work on the knitting mechanism 5, the staff controls the electric sliding group 11 to lower the two protective housings 101 to the same height as the other two non - movable protective housings 101, and then controls the hydraulic cylinder 10 to move the protective housing 101 inward to reset and protect the traction and winding mechanism 2 of the circular weft knitting machine as shown in the appendix Figure 1 As shown. Similarly, when the staff needs to enter the lubricating and dust extraction mechanism 1 to repair or perform other work on the traction and winding mechanism 2, the staff can control the hydraulic cylinder 10 to push the connected protective housing 101 outward, and then control the electric sliding group 11 to push the two opposite protective housings 101 to move upward along the electric slide rail 12, so as to repair and maintain the equipment inside the protective housing 101.
[0040] The protective housing 101 and the control box in the electrical control mechanism 3 are staggered, and the electrical control mechanism 3 is electrically connected to the lubricating dust extraction mechanism 1, the traction winding mechanism 2, the electrical control mechanism 3, and the driving mechanism 6, facilitating the staff to control the lubricating dust extraction mechanism 1, the traction winding mechanism 2, and the driving mechanism 6 to cooperate with each other through the electrical control mechanism 3 to complete the relevant operations required for knitting, and thereby improving the automation integration level of the device.
[0041] A liquid level analysis component 109 is arranged inside the storage tank 106, and the liquid level analysis component 109 is used to detect the usage situation of the lubricating oil. The liquid level analysis component 109 includes a fixing frame 1091, and the top of the fixing frame 1091 is fixedly connected to the inner top of the storage tank 106. At the same time, a floating plate 1097 is arranged below the fixing frame 1091. An elevating plate 1093 and a pressing switch 1095 are arranged inside the fixing frame 1091. The elevating plate 1093 is connected to the inner top of the fixing frame 1091 through a reset spring group 1092. The elevating plate 1093 is arranged above the pressing switch 1095, and the bottom of the elevating plate 1093 is connected to a heat conducting plate 1096 through a nylon thread 1094. After the oil injector 107 sprays the lubricating oil onto the knitting mechanism 5, there is a problem that the staff cannot intuitively understand the remaining amount of the lubricating oil inside the storage tank 106. Therefore, it is necessary to use the liquid level analysis component 109. When the liquid level of the lubricating oil inside the storage tank 106 drops, the floating plate 1097 floating on its top moves down synchronously, thereby pulling the nylon thread 1094 to stretch. When the liquid level, that is, the floating plate 1097 moves down to a specific distance, the nylon thread 1094 is in a fully stretched state. At this time, if the liquid level continues to drop, the floating plate 1097 and the related components above it will pull the elevating plate 1093 to move down under the action of gravity through the nylon thread 1094. When the elevating plate 1093 contacts the pressing switch 1095, the pressing switch 1095 controls the warning light to flash for warning.
[0042] Sliders 1098 are symmetrically arranged on the side surface of the floating plate 1097, and the sliders 1098 are slidably connected inside the storage tank 106. A heat conducting plate 1096 is fixedly connected to the top of the floating plate 1097, and a heat conducting rod 1099 is connected to the bottom of the heat conducting plate 1096. At the same time, the heat conducting rod 1099 penetrates through the floating plate 1097. During the process of the air pump 102 sucking cotton fluffs, the waste heat is synchronously sucked into the storage tank 106 and then discharged to the outside, that is, it cannot process the waste heat, thus causing environmental pollution. The waste heat entering the storage tank 106 will contact the heat conducting plate 1096, and then the heat conducting plate 1096 adsorbs the waste heat and transfers it to the inside of the lubricating oil through the heat conducting rod 1099 for heat exchange with the lubricating oil in the normal temperature state, thereby avoiding environmental pollution by waste heat. At the same time, since new lubricating oil will be added after the lubricating oil is used up, it will not affect the lubrication work.
[0043] On one outer wall of the radar fan assembly 8, there is a three-color lamp 9. The radar fan assembly 8 is arranged above the knitting mechanism 5. At the same time, the radar fan assembly 8 is driven to rotate by the driving mechanism 6. The radar fan assembly 8 continuously exhausts air during the knitting process to prevent cotton fluffs floating in the air from depositing on the device. At the same time, the three-color lamp 9 is constantly on during the operation of the device to give an intuitive warning to the staff, so as to avoid the staff being injured due to accidentally touching the device during the knitting work because they do not understand the processing situation. At the same time, the radar fan assembly 8, the frame 4, the knitting mechanism 5, the driving mechanism 6, and the yarn feeding mechanism 7 are all conventional components of the circular weft knitting machine, and the specific connection relationship and driving working principle will not be elaborated here.
[0044] Referring to Figure 8 , a knitting method, which includes the above-mentioned circular weft knitting machine, and the knitting method includes the following steps:
[0045] Step 1: Preparation of accessories
[0046] Knitting parameter setting: Operate the electrical control mechanism 3 to debug the relevant parameters according to the production and processing requirements, and replace and select the corresponding crochet needles and crochet cores;
[0047] Step 2: Yarn feeding and knitting
[0048] Knitting operation: The driving mechanism 6 and the yarn feeding mechanism 7 uniformly convey the yarn to the knitting mechanism 5, and use the knitting mechanism 5 to perform knitting;
[0049] Step 3: Drawing and winding
[0050] Continuous winding of the fabric: The traction and winding mechanism 2 uniformly winds the knitted fabric to prevent accumulation or stretching deformation, and removes the cotton fluffs and cotton dust on the fabric through the lubrication and dust extraction mechanism 1.
[0051] Working principle:
[0052] In this embodiment, firstly, according to the knitting requirements, suitable crochet needles, hook cores and related accessories are selected, and then they are installed. Then, the staff controls two sets of relative hydraulic cylinders 10 to push the corresponding protective shells 101 to extend outward, and then controls the electric slide group 11 to move the two sets of protective shells 101 up along the electric slide rail 12 until they move to the outside of the crochet needle and the hook core. Under the suction action of the air pump 102, the two sets of relative dust extraction ports 105 will continuously suck the attached cotton wool and other pollutants, and the cotton wool entering the dust extraction box 103 will be blocked by the filter plate 104. The pollutants are temporarily stored inside the device, thereby cleaning the pollutants. On the other hand, the gas entering the device with the pollutants is filtered by the filter plate 104 and then continuously discharged to the inside of the storage box 106, thereby increasing the pressure inside the storage box 106. When the staff observes through the pressure gauge 1010 that the pressure reaches the set value, the valve on the oil spray nozzle 107 is controlled to open, so that the lubricating oil inside the storage box 106 can be automatically sprayed to the knitting part of the knitting mechanism 5, i.e., the hook needle and the hook core, due to the excessive pressure difference between the inside and the outside, to complete the dust removal and lubrication, and then the hydraulic cylinder 10 and the electric slide group 11 are controlled to reset the protective housing 101;
[0053] The driving mechanism 6 and the yarn feeding mechanism 7 evenly transport the yarn to the knitting mechanism 5, and the knitting mechanism 5 is used for knitting. At the same time, the second motor 205 drives the winding roller 207 to rotate, and the knitted product pulled by the traction roller group 209 is wound up. At the same time, the first motor 202 drives the turntable 203 to rotate to adjust the winding position of the winding roller 207. When the knitted product wound up on the winding roller 207 reaches a certain amount, that is, the winding is saturated, the knitted product contacts the movable mounting seat 2065 to squeeze the connecting spring group 2064, so that the movable conductive block 2063 on the inner side of the movable mounting seat 2065 contacts the fixed conductive block 2062 to form a path, so that the buzzer sounds to signal the staff;
[0054] The radar fan assembly 8 continuously blows air during the weaving process to prevent floating cotton wool from being deposited on the device. At the same time, under the suction action of the air pump 102, the dust extraction port 105 continuously sucks the cotton wool and other pollutants attached to the knitted product to prevent them from being rolled up along with the knitted product.
[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
