Description

Technical Field

[0001] This application relates to the technical field of knitting machines, and more particularly to a knitting machine. Background Technology

[0002] Knitting machines are required in the development of weft-density knitted fabrics.

[0003] As living standards improve, people's pursuit of material culture is gradually increasing, and their requirements for comfort in all aspects of clothing, housing, and transportation are also increasing. In particular, they have the highest requirements for the texture of clothing. The texture and comfort of clothing depend most critically on the quality of the fabric, and knitting machines play a key role in this regard.

[0004] For example, Chinese utility model patent CN209508549U discloses a fabric winding mechanism for a knitting machine, which includes a chassis, bearings, a frame, a rubber roller, a fabric winding roller, a drive arm, and a fabric winding drive device. The frame is rotatably mounted on the chassis via bearings, and the lower end of the drive arm is hinged to the top of the frame. The rubber roller and the fabric winding roller are rotatably mounted on the upper and middle parts of the frame, respectively. The fabric winding drive device is connected to the end of the rubber roller. The fabric winding drive device includes a cylinder, a left swing arm, a right swing arm, a linkage shaft, a left pull rod, a right pull rod, a left ratchet seat, a right ratchet seat, a ratchet, a pawl, a linkage iron plate, a magnet, a magnetically controlled pneumatic valve, and a throttle valve. The piston rod end of the cylinder drives the left ratchet seat through the left swing arm and the left pull rod, and simultaneously drives the right ratchet seat through the linkage shaft, the right swing arm, and the right pull rod, thereby driving the rubber roller to move.

[0005] However, when knitted fabrics are removed from the roll roller, they tend to become loose, and the handling of the fabrics after removal from the roll roller by operators is quite troublesome, resulting in high labor costs and low work efficiency. Summary of the Invention

[0006] In order to facilitate the unloading of knitted fabric from the roll roller, reduce labor costs, and improve work efficiency, this application provides a knitting machine.

[0007] This application provides a knitting machine with the following technical solution: It includes a take-up platform, which is divided into a take-up end and a discharge end along its length. The take-up end is provided with a take-up structure for winding knitted fabric. The discharge end is used to place a mandrel. A pusher structure is provided on the take-up end away from the discharge end for pushing the knitted fabric wound on the take-up structure to the discharge end and coaxially sleeved on the mandrel. A mandrel storage box and a fabric roll trolley are respectively provided on both sides of the discharge end. A gripping structure is provided above the take-up platform. The gripping structure can be positioned and reciprocated between the mandrel storage box and the fabric roll trolley along a direction perpendicular to the length of the take-up platform. The gripping structure can also be positioned and reciprocated along a vertical direction. The gripping structure is used to transport the mandrel stacked in the mandrel storage box to the discharge end and to transport the knitted fabric threaded with the mandrel to the fabric roll trolley.

[0008] By adopting the above technical solution, after the knitted fabric is wound into a tube shape by the winding structure, the pushing structure pushes the tube knitted fabric to the output end and places it on the mandrel, reducing the probability of the knitted fabric becoming loose when it is unloaded. The gripping structure transports the mandrel from the mandrel storage box to the output end and transports the tube knitted fabric with the mandrel on it to the fabric roll trolley. The fabric roll trolley then transports the fabric to the next process, making it easier to unload the knitted fabric from the roll roller, reducing labor costs and improving work efficiency.

[0009] Preferably, the discharge end is provided with two support brackets for placing the mandrel. The two support brackets are spaced apart at the discharge end along the length direction of the winding platform. The two support brackets are a fixed support bracket and a sliding support bracket, respectively. The fixed support bracket is located on the side of the discharge end away from the winding end, and the sliding support bracket is reciprocally slidably connected to the discharge end along the length direction of the winding platform.

[0010] By adopting the above technical solution, when the pusher structure pushes the tubular knitted fabric onto the mandrel placed on the two support brackets, the sliding support bracket slides away from the winding structure along the length direction of the winding platform, making way for the tubular knitted fabric placed on the mandrel.

[0011] Preferably, the winding structure includes a winding roller and a drive motor for driving the winding roller to rotate. A triangular mounting plate for mounting the drive motor is provided on the winding end perpendicular to the upper surface of the winding platform. The drive motor is located on the side wall of the triangular mounting plate away from the discharge end. The output shaft of the drive motor passes through the triangular mounting plate and is coaxially connected to the winding roller. The end of the winding roller away from the drive motor is in contact with one end of the mandrel placed on the support bracket, and the diameter of the winding roller is equal to the diameter of the mandrel.

[0012] By adopting the above technical solution, during the process of the drive motor driving the take-up roller to rotate, the knitted fabric from the knitting process is continuously wound onto the take-up roller. One end of the take-up roller is in contact with the mandrel, and the diameter of the take-up roller is equal to the diameter of the mandrel, which facilitates the tubular knitted fabric to be fitted onto the mandrel.

[0013] Preferably, the pushing structure includes a pushing half-ring and two sliding support columns. The end of the pushing half-ring near the take-up roller is used to abut against one end of the knitted fabric. The pushing half-ring is slidably fitted onto the take-up roller. The two sliding support columns are respectively connected to both ends of the pushing half-ring. The end of the sliding support column away from the pushing half-ring is connected to the take-up platform. The two sliding support columns are synchronously and positionably reciprocated and connected to the take-up platform along the length direction of the take-up platform.

[0014] By adopting the above technical solution, during the synchronous sliding of the two sliding support columns along the length of the winding platform, the pusher half-ring is driven to slide along the length of the winding platform. As the pusher half-ring slides along the length of the winding platform and approaches the winding roller, it pushes the tubular knitted fabric wound on the winding roller to be sleeved on the mandrel.

[0015] Preferably, a sliding groove is formed on the upper surface of the winding platform. The depth direction of the sliding groove is perpendicular to the upper surface of the winding platform, and the length direction of the sliding groove is parallel to the length direction of the winding platform. Two first lead screws are provided on the winding platform. The two first lead screws are arranged parallel to each other and symmetrically in the sliding groove. The length direction of the first lead screws is parallel to the length direction of the sliding groove. Two first lead screw motors for driving the first lead screws to rotate are provided on one side wall of the winding platform. The two first lead screw motors and the two first lead screws correspond one-to-one. One end of the first lead screw passes through the groove wall of the sliding groove and is coaxially connected to the first lead screw motor. The other end of the first lead screw is axially fixed and circumferentially rotatably connected to the groove wall of the sliding groove. The first lead screws are sequentially threaded through the bottom of the sliding support column and the bottom of the sliding support bracket.

[0016] By adopting the above technical solution, the rotation of the first lead screw drives the sliding support bracket to slide back and forth along the length of the winding platform, while simultaneously driving the pusher half-ring to slide back and forth along the length of the winding platform. This allows the pusher half-ring to push the tubular knitted fabric wound on the winding roller onto the mandrel, while the sliding support bracket slides away from the winding structure along the length of the winding platform, making room for the tubular knitted fabric wrapped onto the mandrel.

[0017] Preferably, two second lead screws are provided between the mandrel storage box and the fabric roll trolley. The two second lead screws are parallel to each other and their length directions are perpendicular to the length direction of the winding platform. A sliding crossbeam is provided on the gripping structure. The length direction of the sliding crossbeam is parallel to the length direction of the winding platform. The two second lead screws are symmetrically arranged through the sliding crossbeam. The second lead screws are axially fixed and circumferentially rotatably connected to the winding platform. The lower surface of the sliding crossbeam is used to connect with the gripping structure. The gripping structure is vertically positionable and reciprocatingly slidably connected to the sliding crossbeam.

[0018] By adopting the above technical solution, the second lead screw rotates and the sliding crossbeam slides back and forth along the length of the second lead screw, and the gripping structure is vertically positioned and reciprocally connected to the sliding crossbeam, so that the gripping structure can grab the core rod from the core rod storage box and transport the core rod to the support bracket. After the tubular knitted fabric is put on the core rod, it is then transported to the fabric roll trolley.

[0019] Preferably, two drive cylinders are vertically mounted on the sliding beam, and the two drive cylinders are symmetrically mounted on the sliding beam along its length. The piston rods of the drive cylinders are connected to the gripping structure.

[0020] By adopting the above technical solution, the driving cylinder works to realize the vertically positionable reciprocating sliding of the gripping structure, so that the gripping structure can grasp the mandrel and the tubular knitted fabric sleeved behind the mandrel.

[0021] Preferably, the take-up roller includes an elastic sleeve, a transition sleeve, and a central rotating column. The transition sleeve is coaxially sleeved on the central rotating column, and the outer wall of the central rotating column is tightly attached to the inner wall of the transition sleeve. The central rotating column and the transition sleeve are connected by a connector, which is disposed on the outer wall of the central rotating column and is used to be embedded in the inner wall of the transition sleeve. The output shaft of the drive motor passes through the triangular mounting plate and is coaxially fixed to the central rotating column. A clamping member is provided on the outer wall of the transition sleeve, which is used to slide radially along the take-up roller to abut against the inner wall of the elastic sleeve. The outer wall of the elastic sleeve is used for the knitted fabric to be wrapped and wound.

[0022] By adopting the above technical solution, when the knitted fabric begins to be wound on the take-up roller, the radial sliding adjustment of the clamping member causes the clamping member to abut against the inner wall of the elastic sleeve, so that the outer wall of the elastic sleeve is in close contact with the knitted fabric; when it is necessary to remove the knitted fabric, simply slide the clamping member radially to move the clamping member away from the elastic sleeve, making it easy to remove the knitted fabric from the take-up roller.

[0023] Preferably, the clamping element includes more than one clamping plate, and the plurality of clamping plates are arranged at equal angular intervals along the circumference of the transition sleeve. The length direction of the clamping plate is parallel to the axial direction of the transition sleeve, and the central rotating column is provided with an adjusting element for driving the clamping plate to slide and abut against the inner wall of the elastic sleeve.

[0024] By adopting the above technical solution, the adjusting component drives the pressing plate to abut against the inner wall of the elastic sleeve, so that the outer wall of the elastic sleeve is in close contact with the knitted fabric, which is more convenient; when it is necessary to remove the knitted fabric, the pressing plate can be moved away from the elastic sleeve by simply adjusting the component, making it easy to remove the knitted fabric from the take-up roller.

[0025] Preferably, the transition sleeve has more than one limiting plate along its length. The multiple limiting plates are spaced at equal angles along the circumference of the transition sleeve. The limiting plates are reciprocally slidably connected to the transition sleeve along its axial direction. The elastic sleeve has a limiting opening through which the limiting plates slide. The limiting opening corresponds to each limiting plate and extends radially through the elastic sleeve. The length direction of the limiting opening is parallel to the axial direction of the elastic sleeve.

[0026] Since the size of each batch of knitted fabrics is not exactly the same, by adopting the above technical solution, the limiting plate can slide in a positionable manner along the transition sleeve axis to adapt to knitted fabrics of different sizes, so that the knitted fabrics can be wound more neatly on the take-up roller.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. After the knitted fabric is wound into a tube shape by the winding structure, the pushing structure pushes the tube knitted fabric to the output end and puts it on the mandrel, reducing the probability of the knitted fabric becoming loose when it is unloaded. The gripping structure transports the mandrel from the mandrel storage box to the output end and transports the tube knitted fabric with the mandrel on it to the fabric roll trolley. The fabric roll trolley is then used to transport the fabric to the next process, which makes it easier to unload the knitted fabric from the roll roller, reducing labor costs and improving work efficiency.

[0029] 2. When the knitted fabric begins to wind onto the take-up roller, the radial sliding adjustment of the abutment causes the abutment to abut against the inner wall of the elastic sleeve, so that the outer wall of the elastic sleeve is in close contact with the knitted fabric. When it is necessary to remove the knitted fabric, simply slide the radial adjustment of the abutment to move the abutment away from the elastic sleeve, so that the knitted fabric can be easily removed from the take-up roller.

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] This application discloses a knitting machine for facilitating the unloading of knitted fabric from the roll roller, thereby reducing labor costs and improving work efficiency.

[0038] refer to Figure 1 , Figure 2A knitting machine includes a take-up platform 110. In this embodiment, the take-up platform 110 is a cuboid worktable. The take-up platform 110 is divided into a take-up end 1101 and a discharge end 1102 along its length. The take-up end 1101 is provided with a take-up structure 120 for winding knitted fabric, and the discharge end 1102 is provided with two support brackets 130 for placing mandrels 11. The two support brackets 130 extend along the length of the take-up platform 110. The fabric is spaced at intervals along the direction of the discharge end 1102. The take-up end 1101, away from the discharge end 1102, is equipped with a pusher structure 140 for pushing the knitted fabric wound on the take-up structure 120 to the discharge end 1102 and coaxially sleeved on the mandrel 11. Mandrel storage boxes 111 and fabric roll trolleys 112 are respectively provided on both sides of the discharge end 1102. Gantry frames 113 are provided on opposite sides of both the mandrel storage box 111 and the fabric roll trolley 112. The two gantry frames 113... Two second lead screws 114 and a sliding crossbeam 115 are provided. The two second lead screws 114 are parallel to each other and their length direction is perpendicular to the length direction of the winding platform 110. The two ends of the second lead screws 114 are axially fixed and circumferentially rotatable to the two gantry frames 113 respectively. One end of the second lead screw 114 passes through the gantry frame 113 and is coaxially connected to a second lead screw motor 116. The second lead screw motor 116 is fixedly mounted on the gantry frame 113. The length direction of the sliding crossbeam 115 is parallel to the length direction of the winding platform 110. The two second lead screws 114 are symmetrically arranged through the sliding crossbeam 115. Two drive cylinders 117 are vertically arranged through the sliding crossbeam 115. The two drive cylinders 117 are symmetrically arranged through the sliding crossbeam 115 along its length direction. A gripping structure 118 is provided below the sliding crossbeam 115. The piston rod of the drive cylinder 117 is connected to the gripping structure 118.

[0039] After the knitted fabric is wound into a tube shape by the winding structure 120, the pushing structure 140 pushes the tube knitted fabric to the output end 1102 and puts it on the mandrel 11, reducing the probability of the knitted fabric becoming loose when it is unloaded. The gripping structure 118 is used to transport the mandrel 11 stacked in the mandrel storage box 111 to the support bracket 130, and after the tube knitted fabric is put on the mandrel 11, it is transported to the fabric roll trolley 112. The fabric roll trolley 112 transports it to the next process, which makes it easier to unload the knitted fabric from the roll roller, reducing labor costs and improving work efficiency.

[0040] Specifically, refer to Figure 2 , Figure 3The winding structure 120 includes a winding roller 1201 and a drive motor 1202 for rotating the winding roller 1201. The winding roller 1201 includes an elastic sleeve 12011, a transition sleeve 12012, and a central rotating column 12013. The transition sleeve 12012 is coaxially sleeved on the central rotating column 12013. The outer wall of the central rotating column 12013 is in close contact with the inner wall of the transition sleeve 12012. The central rotating column 12013 and the transition sleeve 12012 are connected by a connector. The connector is disposed on the outer wall of the central rotating column 12013 and is used to be embedded in the inner wall of the transition sleeve 12012. In this embodiment, the connector is two connecting plates 121. Two connecting plates 121 are symmetrically arranged on the outer wall of the central rotating column 12013. The length direction of the connecting plates 121 is parallel to the axial direction of the central rotating column 12013. Correspondingly, the inner wall of the transition sleeve 12012 is provided with two connecting slots 122 for the two connecting plates 121 to be embedded. A triangular mounting plate 119 for mounting the drive motor 1202 is provided on the winding end 1101 perpendicular to the upper surface of the winding platform 110. The drive motor 1202 is located on the side wall of the triangular mounting plate 119 away from the discharge end 1102. The output shaft of the drive motor 1202 passes through the triangular mounting plate 119 and is coaxially fixed to the central rotating column 12013.

[0041] refer to Figure 1 , Figure 2 The outer wall of the transition sleeve 12012 is provided with a clamping member. The clamping member is used to slide radially along the take-up roller 1201 to abut against the inner wall of the elastic sleeve 12011. The outer wall of the elastic sleeve 12011 is for the knitted fabric to be wrapped and wound. The end of the take-up roller 1201 away from the drive motor 1202 is in contact with the end of the mandrel 11 placed on the support bracket 130, and the diameter of the take-up roller 1201 is equal to the diameter of the mandrel 11.

[0042] refer to Figure 2 , Figure 4 Furthermore, the clamping element includes more than one clamping plate 123. In this embodiment, two clamping plates 123 are provided. The two clamping plates 123 are arranged at equal angles along the circumference of the transition sleeve 12012. The length direction of the clamping plate 123 is parallel to the axial direction of the transition sleeve 12012. An adjusting member 150 is provided on the central rotating column 12013 to drive the clamping plate 123 to slide and abut against the inner wall of the elastic sleeve 12011. The adjusting member 150 drives the clamping plate 123 to abut against the inner wall of the elastic sleeve 12011, so that the outer wall of the elastic sleeve 12011 is tightly attached to the knitted fabric, which is more convenient. When it is necessary to remove the knitted fabric, the clamping plate 123 can be moved away from the elastic sleeve 12011 by adjusting the adjusting member 150, which makes it easy to remove the knitted fabric from the take-up roller 1201.

[0043] In this embodiment, the adjusting member 150 includes an adjusting disc 1501, a second limiting block 1502, and an adjusting nut 1503. The adjusting disc 1501 is disposed on the side of the triangular mounting plate 119 away from the drive motor 1202. Two sliding openings 151 are radially penetrating the adjusting disc 1501, allowing two abutment plates 123 to pass through and slide. A first limiting block 152 is fixedly sleeved on the end of the abutment plate 123 near the rotating disc. When the abutment plate 123 passes through the sliding opening 151, the first limiting block 152 moves closer to the rotating disc. The end face of the moving plate abuts against the rotating plate, and the end of the clamping plate 123 that passes through the rotating plate is slidably connected to the second limiting block 1502. The end of the clamping plate 123 that passes through the sliding opening 151 extends coaxially with the adjusting screw 153. The second limiting block 1502 is slidably sleeved on the adjusting screw 153. The second limiting block 1502 is used to abut against the end face of the rotating plate away from the winding roller 1201. The adjusting nut 1503 is threadedly sleeved on the adjusting screw 153 and is used to abut against the side wall of the second limiting block 1502 away from the rotating plate.

[0044] Furthermore, refer to Figure 2 , Figure 3 Two mounting plates 124 are provided on the central rotating column 12013. The two mounting plates 124 and two connecting plates 121 are arranged at equal angles along the circumference of the central rotating column 12013 on the outer wall of the central rotating column 12013. The length direction of the mounting plates 124 is parallel to the axial direction of the central rotating column 12013. The mounting plates 124 and the abutting plates 123 correspond one-to-one. An inclined plate 125 connects the mounting plates 124 and the abutting plates 123. Every two inclined plates 125 form a group. The two inclined plates 125 in each group are located on both sides of the mounting plate 124. The ends are rotatably connected to the mounting plate 124 and the abutment plate 123 respectively. In this embodiment, two sets of inclined plates 125 are arranged at intervals along the length direction of the mounting plate 124. The transition sleeve 12012 has a transition opening 126 that allows the inclined plates 125 to pass through in the radial direction. The transition opening 126 and the abutment plate 123 correspond one-to-one and the length direction of the transition opening 126 is parallel to the axial direction of the transition sleeve 12012. When the adjusting member 150 drives the abutment plate 123 to abut against the inner wall of the elastic sleeve 12011, the acute angle between the mounting plate 124 and the inclined plate 125 will increase.

[0045] refer to Figure 2Since the size of each batch of knitted fabrics is not exactly the same, the transition sleeve 12012 is provided with more than one limiting plate 160. In this embodiment, a total of two limiting plates 160 are provided. The two limiting plates 160 are equally spaced along the circumference of the transition sleeve 12012. The limiting plates 160 are axially positioned and reciprocally slidable to the transition sleeve 12012. The elastic sleeve 12011 has a limiting opening 161 through which the limiting plates 160 slide. The limiting opening 161 corresponds one-to-one with the limiting plates 160. The limiting opening 161 passes radially through the elastic sleeve 12011. The length direction of the limiting opening 161 is parallel to the axial direction of the elastic sleeve 12011. The limiting plates 160 are axially positioned and slidable along the transition sleeve 12012, which is suitable for knitted fabrics of different sizes, so that the knitted fabrics can be wound more neatly on the take-up roller 1201.

[0046] Specifically, refer to Figure 5 A dovetail block 162 extends from one end of the limiting plate 160 near the transition sleeve 12012. A dovetail limiting groove 163 is provided along the axial direction of the transition sleeve 12012 for the dovetail block 162 to be inserted and slid. A slot 164 is provided on the end face of the dovetail block 162 near the end of the dovetail limiting groove 163. A positioning hemisphere 165 is slidably connected in the slot 164. The positioning hemisphere 165 is connected to the bottom of the slot 164 by a return spring 166. The bottom of the dovetail limiting groove 163 is provided along the axial direction for more than one positioning groove 167 for the positioning hemisphere 165 to be inserted. The multiple positioning grooves 167 are equally spaced along the axial direction of the transition sleeve 12012.

[0047] refer to Figure 1 , Figure 2 Furthermore, a sliding groove 170 is provided on the upper surface of the winding platform 110. The depth direction of the sliding groove 170 is perpendicular to the upper surface of the winding platform 110, and the length direction of the sliding groove 170 is parallel to the length direction of the winding platform 110. Two first lead screws 171 are provided on the winding platform 110. The two first lead screws 171 are arranged parallel to each other and symmetrically in the sliding groove 170. The length direction of the first lead screws 171 is parallel to the length direction of the sliding groove 170. Two first lead screw motors 172 are provided on one side wall of the winding platform 110 to drive the first lead screws 171 to rotate. The two first lead screw motors 172 correspond one-to-one with the two first lead screws 171. One end of the first lead screw 171 passes through the groove wall of the sliding groove 170 and is coaxially connected to the first lead screw motor 172. The other end of the first lead screw 171 is axially fixed and circumferentially rotatable to the groove wall of the sliding groove 170.

[0048] The two support brackets 130 are a fixed support bracket 1301 and a sliding support bracket 1302. The fixed support bracket 1301 is located on the side of the discharge end 1102 away from the take-up end 1101, and the bottom of the sliding support bracket 1302 is embedded in the sliding groove 170. The pushing structure 140 includes a pushing half-ring 1401 and two sliding support columns 1402. The end of the pushing half-ring 1401 near the take-up roller 1201 is used to abut against one end of the knitted fabric. The pushing half-ring 1401 is used to slide and fit on the take-up roller 1201. The two sliding support columns 1402 are respectively connected to the two ends of the pushing half-ring 1401. In this embodiment, the sliding support columns 1402 are located away from the pushing half-ring 1401. One end is connected to a sliding plate 141, which is embedded in a sliding groove 170. A first lead screw 171 is threaded through the bottom of the sliding plate 141 and the sliding support bracket 1302. The rotation of the first lead screw 171 drives the sliding support bracket 1302 to slide back and forth along the length of the winding platform 110, while simultaneously driving the pusher half-ring 1401 to slide back and forth along the length of the winding platform 110. This causes the pusher half-ring 1401 to push the tubular knitted fabric wound on the winding roller 1201 onto the mandrel 11. At the same time, the sliding support bracket 1302 slides away from the winding structure 120 along the length of the winding platform 110, making room for the tubular knitted fabric wrapped onto the mandrel 11.

[0049] The implementation principle of a knitting machine according to an embodiment of this application is as follows: After the knitted fabric is wound into a tubular shape by the winding structure 120, the pushing structure 140 pushes the tubular knitted fabric to the output end 1102 and places it on the mandrel 11, reducing the probability of the knitted fabric becoming loose when it is unloaded. The gripping structure 118 is used to transport the mandrel 11 stacked in the mandrel storage box 111 to the support bracket 130, and after the tubular knitted fabric is placed on the mandrel 11, it is transported to the fabric roll trolley 112. The fabric roll trolley 112 transports the fabric to the next process, which facilitates the unloading of the knitted fabric from the roll roller, reduces labor costs, and improves work efficiency.

[0050] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
