[0015] Compared with the prior art, the invention has the following beneficial effects: the circular weft knitting machine and the knitting method are (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 inside 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. (2) The present invention can effectively solve the problem of the protective shell located on the outside of the fabric winding assembly of the existing circular knitting machine 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 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 temperature of the device to be too high and cause the malfunction of the fabric winding assembly. 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, under the suction action of the air pump, the dust extraction port extracts the cotton wool attached to the fabric 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.

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-9The present invention provides a technical solution: a weaving circular knitting machine, comprising a lubricating dust extraction mechanism 1, an electrical control mechanism 3, a frame 4, a weaving mechanism 5, a driving mechanism 6, a yarn feeding mechanism 7 and a radar fan assembly 8, wherein the frame 4 is provided with a driving mechanism 6 inside, and the driving mechanism 6 is used to drive the weaving mechanism 5 and the yarn feeding mechanism 7, the electrical control mechanism 3 comprises a control panel, a warning light and a buzzer, the traction and winding mechanism 2 comprises a mounting frame 204, a traction roller group 209 is provided inside the mounting frame 204, and a winding roller 207 is provided below the traction roller group 209, a winding detection assembly 206 is provided outside the winding roller 207, and the winding detection assembly 206 passes The over-limiting member 208 is connected to both ends of the winding roller 207, a second motor 205 is provided on one side of the mounting frame 204, and a receiving roll detection assembly 206 is fixed to the output end of the second motor 205, and the winding detection assembly 206 includes a limit plate 2061, and the inner wall of the limit plate 2061 contacts both ends of the winding roller 207, a fixed conductive block 2062 is installed in the top of the limit plate 2061, and a movable conductive block 2063 is provided below the fixed conductive block 2062, and the fixed conductive block 2062 is arranged opposite to the movable conductive block 2063, and a movable mounting seat 2065 is provided below the winding roller 207, and the movable mounting seat 2065 is connected to the spring group 2061. 064 is fixedly connected to the inner top of the limit plate 2061, and the mobile conductive block 2063 is installed in the top of the mobile mounting seat 2065. When working, first connect the power supply, operate the control panel to start the device, and the driving mechanism 6 drives the yarn feeding mechanism 7 to continuously feed the yarn to be processed into the hook in the knitting mechanism 5 to cooperate with the hook for knitting. At the same time, the radar fan assembly 8 continues to blow air to prevent floating pollutants from being deposited on the device. Then the knitted product is reeled in by the traction and reeling mechanism 2. The reeling operation is specifically manifested as the second motor 205 drives the reeling roller 207 to rotate and reel in the knitted product pulled inside the traction roller group 209. When the reeling roller 207 When the knitted product wound up reaches a certain amount, that is, the winding is saturated, the knitted product above it contacts and squeezes the movable mounting seat 2065, and at the same time, the mounting seat 2065 moves to compress the connecting spring group 2064, so that the movable conductive block 2063 on the inner side of the movable mounting seat 2065 contacts with the fixed conductive block 2062 to form a passage, and then the buzzer connected in series on the passage will sound to remind the staff to replace the winding roller 207, so as to ensure the uniformity of winding, and then the staff can remove the limit piece 208 to separate the winding roller 207 and the winding detection assembly 206, and then the winding roller 207 can be removed from the inner side of the winding detection assembly 206 for replacement.

[0020] The traction and winding mechanism 2 also includes a base 201, and a first motor 202 is installed in 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 fixed to the bottom of the mounting frame 204. The existing circular weft knitting machine is prone to damage due to the fixed winding position during the winding process, which causes the product that is far away from the winding component to be stretched too much for a long time. When performing the winding operation, the first motor 202 synchronously drives the turntable 203 to rotate the winding position of the winding roller 207 for rotation and adjustment, thereby avoiding the product from being pulled and damaged due to the deviation of the winding distance.

[0021] The lubricating dust extraction mechanism 1 includes a protective shell 101, and the protective shell 101 is provided with four groups, and an air pump 102 is installed on the inner wall of the corresponding two groups of protective shells 101, and a dust extraction box 103 is arranged above the air pump 102, and the air inlet end of the air pump 102 is connected to the bottom of the dust extraction box 103 through a pipeline, and a filter plate 104 is installed inside the dust extraction box 103, and dust extraction ports 105 are evenly opened on the inner wall of the dust extraction box 103. During long-term use, the weaving part of the weaving mechanism 5 is prone to the phenomenon of cotton wool entangled and attached to the crochet needle, which causes the crochet needle to jam and affect its normal operation. When the weaving mechanism 5 needs to be cleaned, the air pump 102 is started. Under the suction action of the air pump 102, the dust extraction port 105 will continuously suck the cotton wool attached to the crochet needle and other pollutants, and the cotton wool entering the dust extraction box 103 is temporarily stored inside the device under the obstruction of the filter plate 104, thereby achieving the cleaning of pollutants; The lubricating dust extraction mechanism 1 also includes a storage box 106, and the storage box 106 is arranged below the dust extraction box 103, and the storage box 106 is connected to the exhaust end of the air pump 102 through a pipeline, and the inner wall of the storage box 106 is evenly provided with oil nozzles 107, and the outer wall of the storage box 106 is fixedly connected with an automatic pressure relief valve 1011, and a pressure gauge 1010 is installed on the automatic pressure relief valve 1011. After dust removal, in order to ensure the smoothness of the operation of the weaving mechanism 5, the crochet needles on the weaving mechanism 5 need to be lubricated. During operation, the filtered gas enters the storage box 106, and then the pressure inside the storage box 106 increases. When the staff observes through the pressure gauge 1010 that the pressure reaches the set value, the control The valve on the oil spray nozzle 107 is opened, so that the lubricating oil inside the storage box 106 can be automatically sprayed onto the weaving part of the weaving mechanism 5 due to the excessive pressure difference between the inside and the outside. It should be explained here that the oil spraying time of the oil spray nozzle 107 is preferably 2-3 seconds, and after the oil spraying is completed, there is still a large pressure difference inside and outside the storage box 106. At this time, the staff can open the automatic pressure relief valve 1011 to relieve the pressure 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 removing the inspection plate engaged on it, and at the same time, the connection of the inspection plate is sealed.

[0022] A hydraulic cylinder 10 is provided 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 shell 101, an electric slide group 11 is provided on the inner side of the hydraulic cylinder 10, and an electric slide rail 12 is provided on one side of the electric slide group 11, the fixed end of the hydraulic cylinder 10 is installed on the electric slide group 11, and on the electric slide rail 12 on one side of the electric slide group 11, a traction and winding mechanism 2 is provided on the inner side of the dust extraction box 103, and the traction and winding mechanism 2 is used to wind up the knitted fabric. When the staff does not need to perform dust removal work on the weaving mechanism 5, the staff controls the electric slide group 11 to move the two groups of protective shells 101 downward to the same height as the other two groups of protective shells 101 that will not move, and then controls the protective shell 101 to move inward and reset through the hydraulic cylinder 10 to protect the traction and winding mechanism 2 of the weaving circular weft knitting machine as shown in the attached figure. Figure 1 As shown, similarly, when the staff needs to enter the lubrication and dust extraction mechanism 1 to inspect the traction and winding mechanism 2 or perform other work, the staff can control the hydraulic cylinder 10 to push the protective shell 101 connected to it to move outward, and then control the electric slide group 11 to push the two groups of relative protective shells 101 up along the electric slide rail 12, and then the equipment inside the protective shell 101 can be inspected and maintained.

[0023] The protective shell 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 and winding mechanism 2, the electrical control mechanism 3 and the driving mechanism 6, so that the staff can control the lubricating dust extraction mechanism 1, the traction and winding mechanism 2 and the driving mechanism 6 through the electrical control mechanism 3 to cooperate with each other to complete the relevant operations required for knitting, thereby improving the automation integration level of the device.

[0024] A liquid level analysis component 109 is provided inside the storage box 106, and the liquid level analysis component 109 is used to detect the use 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 box 106, and a floating plate 1097 is provided below the fixing frame 1091. A lifting plate 1093 and a pressing switch 1095 are provided inside the fixing frame 1091, and the lifting plate 1093 is connected to the inner top of the fixing frame 1091 through a reset spring group 1092. The lifting plate 1093 is arranged above the pressing switch 1095, and the bottom of the lifting plate 1093 is connected to the heat conducting plate 1096 through a nylon line 1094, and the fuel injector 107 is moved to the fuel injector 107. After spraying the lubricating oil onto the weaving mechanism 5, there is a problem that the staff cannot intuitively understand the remaining lubricating oil in the storage box 106. Therefore, the liquid level analysis component 109 is needed. When the lubricating oil level inside the storage box 106 drops, the floating plate 1097 floating on the top thereof moves down synchronously, thereby pulling the nylon line 1094 to stretch. When the liquid level, i.e., the floating plate 1097, moves down to a specific distance, the nylon line 1094 is in a fully extended state. At this time, if the liquid level continues to move down, the floating plate 1097 and the related components above it will pull the lifting plate 1093 down through the nylon line 1094 under the action of gravity. When the lifting plate 1093 contacts the push switch 1095, the push switch 1095 controls the warning light to flash as a warning.

[0025] Sliders 1098 are symmetrically arranged on the sides of the floating plate 1097, and the sliders 1098 are slidably connected to the inside of the storage box 106. The top of the floating plate 1097 is fixedly connected to the heat conducting plate 1096, and the bottom of the heat conducting plate 1096 is connected to the heat conducting rod 1099. At the same time, the heat conducting rod 1099 is arranged through the floating plate 1097. During the process of the air pump 102 sucking the cotton wool, the waste heat is simultaneously sucked into the inside of the storage box 106 and then discharged to the outside, that is, it cannot process the waste heat, thereby causing environmental pollution. The waste heat entering the storage box 106 will contact the heat conducting plate 1096, and then the heat conducting plate 1096 absorbs the waste heat and transfers it to the inside of the lubricating oil through the heat conducting rod 1099, and exchanges heat with the lubricating oil at room temperature, thereby avoiding waste heat polluting the environment. 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.

[0026] A three-color light 9 is arranged on the outer wall of one side of the radar fan assembly 8, and the radar fan assembly 8 is arranged above the weaving 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 weaving process to prevent cotton wool floating in the air from being deposited on the device. At the same time, the three-color light 9 is in a constantly bright state when the device is working, which provides an intuitive warning to the staff and prevents the staff from accidentally touching the device and causing injuries due to unclear processing conditions during the knitting process. At the same time, the radar fan assembly 8, the frame 4, the weaving mechanism 5, the driving mechanism 6 and the yarn feeding mechanism 7 are all conventional components of the weaving circular weft knitting machine, and their specific connection relationship and driving working principle will not be repeated here.

[0027] Reference Figure 8 , a knitting method, the knitting method comprising the above-mentioned circular weft knitting machine, the knitting method comprising the following steps: Step 1: Accessories preparation Knitting parameter setting: According to the production and processing requirements, operate the relevant parameters of the electrical control mechanism 3 pairs to debug, and change and select the corresponding hook and hook core; Step 2: Feeding yarn and knitting Knitting operation: 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; Step 3: Pull and reel Continuous fabric winding: The traction winding mechanism 2 evenly winds the woven fabric to prevent accumulation or stretching deformation, and removes cotton wool and cotton dust on the fabric by lubricating the dust extraction mechanism 1.

[0028] Working principle: 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; 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; 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.

[0029] 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.
