Description

Technical Field

[0001] This application relates to a scissor mechanism and a method for cutting and clamping threads, belonging to the field of knitting machinery mechanisms. Background Technology

[0002] Both horizontal knitting machines and glove knitting machines can be used to knit fabrics, and their knitting principles are similar. The needle selection mechanism controls the hooks to form loops in the yarn, and the scissors and thread fork mechanism are used to cut the yarn. As shown in patent number CN201820387146.X, it consists of a drive device and a scissor mechanism. The drive device moves the scissor mechanism to the target position. However, this scissor mechanism only has the function of cutting the yarn, and the position and direction of the yarn end cannot be controlled after cutting.

[0003] When a horizontal knitting machine finishes knitting one section and needs to knit another section, the yarn needs to be cut to prevent the two sections from joining together. The existing scissor mechanism does not control the cut yarn after cutting, which results in the end of the yarn being exposed outside the fabric, requiring manual processing of the end of the yarn.

[0004] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide a scissor mechanism and a weaving process to overcome the defects in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a scissor mechanism that can reduce the amount of thread ends at the end of woven products.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a scissor mechanism, including a main scissor assembly, a secondary scissor assembly, and a scissor part disposed on a guide rail. The main scissor assembly and the secondary scissor assembly are in a clutch-engagement relationship. The scissor part is disposed between the main scissor assembly and the secondary scissor assembly. When the main scissor assembly and the secondary scissor assembly hook and clamp the yarn, the scissor part is driven to cut the yarn.

[0007] A scissor mechanism of the present invention is further configured such that: the main scissor assembly clamps and releases yarn via a first swing member, and the auxiliary scissor assembly clamps and releases yarn via a second swing member; the main scissor assembly moves laterally via a first horizontal drive member, and the auxiliary scissor assembly moves laterally via a second horizontal drive member; when the main scissor assembly and the auxiliary scissor assembly are combined, they can hook the yarn on the horizontal knitting machine to the scissor section; when the main scissor assembly and the auxiliary scissor assembly are separated, they can clamp the yarn respectively and release the yarn at the yarn feeding point.

[0008] A scissor mechanism of the present invention is further configured such that: the main scissor assembly is mounted on a guide rail via a first scissor base plate; the main scissor assembly includes a first hook and a first clamp; the first hook and the first clamp are slidably connected to the first scissor base plate via a first clamp guide rail; when the first swinging member moves, the first swinging member drives the first hook and the first clamp to move via a first transmission device.

[0009] A scissor mechanism of the present invention is further configured such that: a secondary scissor assembly is mounted on a guide rail via a second scissor base plate; the secondary scissor assembly includes a second hook and a second clamp; the second hook and the second clamp are slidably connected to the first scissor base plate via a second clamp guide rail; when the second swing member moves, the second swing member drives the second hook and the second clamp to move via a second transmission device.

[0010] A scissor mechanism of the present invention is further configured such that: the first transmission device includes a first hook rotating rod, one end of the first hook rotating rod is rotatably connected to the first scissor base plate, and the other end of the first hook rotating rod is pivotally connected to a first cam connecting rod. When the first swinging member is activated, the first hook rotating rod rotates in conjunction with the first cam, which moves horizontally in conjunction with the first cam, and the first cam connecting rod slides along the direction of the first clamp guide rail in conjunction with the first wire clamp and the first wire hook.

[0011] The scissor mechanism of the present invention is further configured such that: the main scissor assembly further includes a scissor control component, which is installed on the side of the main scissor assembly near the auxiliary scissor assembly, and is used to control the movement of the scissor section.

[0012] A scissor mechanism of the present invention is further configured such that: the scissor control device is driven by the first swing member or the second swing member.

[0013] The scissor mechanism of the present invention is further configured to include a plurality of limiting blocks, which are fixedly connected to the movement path of the first clamp and the second clamp.

[0014] An elastic component is provided between the first line clamp and the first line hook.

[0015] A method for cutting and clamping wire according to the present invention includes the following steps:

[0016] 1. Outlining

[0017] When the horizontal knitting machine completes the knitting of one section and needs to move to the next section, the scissor mechanism moves laterally in the horizontal direction and moves above the yarn to be cut.

[0018] Driven by the first and second oscillating components, the first and second hooks of the scissor mechanism move downward and hook the yarn;

[0019] 2. Cut the thread

[0020] Driven by the first and second oscillating components, the first hook and the first clamp of the scissor mechanism hold one end of the yarn, and the second hook and the second clamp of the scissor mechanism hold the other end of the yarn. Under the control of the scissor control mechanism, the scissor section of the scissor mechanism opens and closes to cut the yarn.

[0021] 3. Loose threads

[0022] After the yarn is cut, the first and second clamps hold the two ends of the cut yarn respectively. Then, the first or second clamp is moved laterally to the yarn feeding position. When the horizontal braiding machine is weaving the next section, the yarn is unwound under the drive of the first and second swinging parts.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In this invention, the scissor section and the forked section work together to cut the yarn. Then, the first and second thread clamps hold the two ends of the cut yarn respectively. After moving to the working position, the yarn is released, thereby weaving the cut yarn ends into the fabric to realize the processing of the end yarn, reduce labor costs, and improve the level of automation.

[0044] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 9As shown, the present invention relates to a scissor mechanism and a weaving process. A preferred embodiment comprises a frame sequentially equipped with a second swing member 1, a first horizontal drive member 2, a second horizontal drive member 20, and a first swing member 10. The first horizontal drive member 2 includes a first moving motor 21, a first main synchronous pulley 22, and a first auxiliary synchronous pulley 23. The first moving motor 21 is mounted on the frame and drives the first main synchronous pulley 22 to rotate. The first auxiliary synchronous pulley 23 is rotatably connected to the frame via a washer 24. The second horizontal drive member 20 includes... The system includes a second moving motor 201, a second main synchronous pulley 202, and a second auxiliary synchronous pulley 203. The second moving motor 201 is mounted on the frame and drives the second main synchronous pulley 202 to rotate. The second auxiliary synchronous pulley 203 is rotatably connected to the frame via a washer 204. The length of the washer 24 is shorter than the length of the washer 204 to ensure that the position of the second main synchronous pulley 202 corresponds to the position of the first auxiliary synchronous pulley 23, and the position of the first main synchronous pulley 22 corresponds to the position of the second auxiliary synchronous pulley 203.

[0045] One end of the first synchronous belt 5 is fitted onto the first main synchronous belt pulley 22, and the other end is fitted onto the second auxiliary synchronous belt pulley 203. One end of the second synchronous belt 50 is fitted onto the second main synchronous belt pulley 202, and the other end is fitted onto the second auxiliary synchronous belt pulley 203. The main shear assembly 3 is installed on the first synchronous belt 5, and the auxiliary shear assembly 4 is installed on the second synchronous belt 50.

[0046] The first moving motor 21 drives the first synchronous belt 5 to move through the first main synchronous pulley 22, and at the same time drives the main scissor assembly 3 to perform synchronous reciprocating motion. The second moving motor 201 drives the second synchronous belt 50 to move through the second main synchronous pulley 202, and at the same time drives the auxiliary scissor assembly 4 to perform synchronous reciprocating motion.

[0047] Both the main shear assembly 3 and the auxiliary shear assembly 4 include a shear base plate 41. Several supporting rollers 42 and several supporting rollers 43 are mounted on the shear base plate 41. The supporting rollers 42 are installed at one end within the guide rail 6, and the supporting rollers 43 abut against the other end within the guide rail 6. In this embodiment, two rotating sliders 44 are laterally arranged on the shear base plate 41. The shear base plate 41 includes a first shear base plate and a second shear base plate. The rotating sliders 44 are rotatably connected to the shear base plate 41, and the two rotating sliders 44 are... One end of the slide is equipped with an elastic steel strip 45, and the second support roller 43 is mounted on the rotating slider 44. Two steel strips 46 are installed inside the guide rail 6. The first support roller 42 and the second support roller 43 are slidably connected to the two steel strips 46 respectively. The elastic steel strip 45 is used to restrict the rotation of the rotating slider 44, so that the second support roller 43 and the steel strip 46 can abut against each other. This ensures that the main scissor assembly 3 and the auxiliary scissor assembly 4 can be slidably connected on the guide rail 6, and also makes it easy to remove the main scissor assembly 3 and the auxiliary scissor assembly 4 from the guide rail 6.

[0048] The first swinging component 10 includes a first swinging motor 11, a first rotating motor gear 12, a first wire clamp sector gear 13, and a first wire clamp moving shaft 14.

The first wire clamp moving shaft 14 is mounted on the first wire clamp sector gear 13. The first swinging motor 11 drives the first rotating motor gear 12 to swing back and forth in conjunction with the first wire clamp sector gear 13 by rotating back and forth, while simultaneously realizing the back and forth rotation of the first wire clamp moving shaft 14.

[0049] In this embodiment, the cross-section of the first wire clamp moving shaft 14 is semi-circular, but it can also be other shapes, such as rectangle, triangle, etc.

[0050] The second swinging component 1 includes a second swinging motor 101, a second rotating motor gear 102, a second wire clamp sector gear 103, and a second wire clamp moving shaft 104. The second rotating motor gear 102 is mounted on the output shaft of the second swinging motor 101, and the second rotating motor gear 102 meshes with the second wire clamp sector gear 103. The second wire clamp moving shaft 104 is mounted on the second wire clamp sector gear 103. The second swinging motor 101 drives the second rotating motor gear 102 to swing back and forth in conjunction with the second wire clamp sector gear 103 by rotating back and forth, while simultaneously realizing the back and forth rotation of the second wire clamp moving shaft 104. In this embodiment, the cross-section of the first wire clamp moving shaft 14 is semi-circular, but it can also be other shapes, such as rectangles, triangles, etc.

[0051] The main scissor assembly 3 includes a scissor section, a scissor control mechanism, and a first forked wire section. A first swing member 10 controls the operation of the first scissor section and the first forked wire section. The first forked wire section includes a first hook 327, a first clamp 328, and a first transmission mechanism. The first transmission mechanism includes a first clamp guide rail 320, a first cam connecting rod 321, a first connecting swing block 322, a first hook rotating rod 323, a first positioning shaft 324, a first rotating rod pressure plate 325, and a first clamp swing block fixing seat 326. One end of the first connecting swing block 322 and the first hook rotating rod 323 is pivotally connected to the scissor base plate 41, and the other end is pivotally connected to the first cam connecting rod 321. When the first connecting swing block 322 and the first hook rotating rod 323 rotate, they move horizontally in conjunction with the first cam connecting rod 321. The first clamp moving shaft 14 passes through the first hook rotating rod 323. The first rotating rod pressure plate 325 is fixedly connected to the first hook rotating rod 323. The pressure plate 325 is used to limit the rotation range of the first wire clamp moving shaft 14. The second wire clamp moving shaft 104 passes through the first connecting swing block 322. When the second wire clamp moving shaft 104 rotates, it cannot drive the first connecting swing block 322. One end of the first positioning shaft 324 is slidably connected to the first cam connecting rod 321, and the other end of the first positioning shaft 324 is slidably connected to the first clamp guide rail 320.

The first wire hook 327 is fixedly connected to the swing block of the first wire clamp 328. The first wire clamp 328 is slidably connected to the swing fixing block of the first wire clamp 328. A first tension spring 329 is fixedly connected between the first wire clamp 328 and the first wire hook 327. A first scissor baffle 3281 is fixedly connected to the first scissor base plate 41. The first scissor baffle 3281 is used to limit the movement of the first wire clamp 328.

[0052] When the first wire clamp moving shaft 14 rotates, it can drive the first rotating rod pressure plate 325 and the first hook rotating rod 323 to move together. At the same time, it is linked to the first cam connecting rod 321 to move horizontally and push the first positioning shaft 324 to move within the first clamp guide rail 320. The first positioning shaft 324 is linked to the first wire clamp 328 swing fixing block and the first wire hook 327. The first wire clamp 328 moves together with the first wire hook 327 through the first tension spring 329 until the first wire clamp 328 contacts the first scissor baffle 3281. The first scissor baffle 3281 provides space for the yarn to enter the first wire clamp 328 and the first wire hook 327.

[0053] The auxiliary scissor assembly 4 includes a second forked wire section, and a second swing member 1 is used for the operation of the second forked wire section. The second forked wire section includes a second hook 427, a second clamp 428, and a first transmission mechanism. The first transmission mechanism includes a second clamp guide rail 420, a second cam connecting rod 421, a second connecting swing block 422, a second hook rotating rod 423, a second positioning shaft (not shown in the figure), a second rotating rod pressure plate 425, and a second clamp swing block fixing seat 426. One end of the second connecting swing block 422 and the second hook rotating rod 423 is pivotally connected to the scissor base plate 41, and the other end is pivotally connected to the second cam connecting rod 421. When the second connecting swing block 422 and the second hook rotating rod 423 rotate, they are linked to the second cam connecting rod 421 to move horizontally. The second clamp moving shaft 104 passes through the second hook rotating rod 423. The second rotating rod pressure plate 425 is fixedly connected to the second hook rotating rod 423. 25 is used to limit the rotation range of the second wire clamp moving shaft 104. The first wire clamp moving shaft 14 passes through the second connecting swing block 422. When the first wire clamp moving shaft 14 rotates, it cannot drive the second connecting swing block 422. One end of the second positioning shaft is slidably connected to the second cam connecting rod 421, and the other end of the second positioning shaft is slidably connected to the second clamp guide rail 420. The second clamp guide rail 420 is fixedly connected to the scissor base plate 41. The second wire clamp swing block fixing seat 426 is fixedly connected to the second positioning shaft. The second wire hook 427 is fixedly connected to the swing block of the second wire clamp 428. The second wire clamp 428 is slidably connected to the second wire clamp swing block fixing seat 426. A second tension spring 429 is fixedly connected between the second wire clamp 428 and the second wire hook 427. A second scissor baffle 4281 is fixedly connected to the second scissor base plate 41. The second scissor baffle 4281 is used to limit the movement of the second wire clamp 428.

[0054] When the second wire clamp moving shaft 104 rotates, it drives the second rotating rod pressure plate 425 and the second hook rotating rod 423 to move together. At the same time, it links the second cam connecting rod 421 to move horizontally and pushes the second positioning shaft to move within the second clamp guide rail 420. The second positioning shaft links the second wire clamp swing block fixing seat 426 and the second wire hook 427. The second wire clamp 428 moves together with the second wire hook 427 through the second tension spring 429 until the second wire clamp 428 contacts the second scissor baffle 4281. The second scissor baffle 4281 provides space for the yarn to enter the second wire clamp 428 and the second wire hook 427.

[0055] The scissor unit includes movable scissors 303 and fixed scissors 304. The scissor control mechanism includes a wire clamping scissor transmission foot 301 and a central swing arm 302. The scissor unit is located between the first line hook 327 and the second line hook 427.

[0056] The drive foot 301 of the wire clamping scissors is fixedly connected to the rotating rod 423 of the second hook. The central swing rod 302 and the movable scissors 303 are rotatably connected to the scissor base plate 41. The rotating rod 423 of the second hook and the central swing rod 302 cooperate with each other. The central swing rod 302 and the movable scissors 303 cooperate with each other. The fixed scissors 304 are fixedly connected to the scissor base plate 41. When the rotating rod 423 of the second hook rotates, it can drive the central swing rod 302 to rotate and link the movable scissors 303 to move. The movable scissors 303 and the fixed scissors 304 cooperate with each other to cut the yarn.

[0057] The tracks of the first clamp guide rail 320 and the second clamp guide rail 420 are arc-shaped, so that the first hook 327 and the second hook 427 can move away from the scissor part when they move, so as to better complete the hooking.

[0058] Scissor baffles 5281 are fixedly connected to the first clamp guide rail 320 and the second clamp guide rail 420 respectively to restrict the movement of the first wire clamp 328 and the second wire clamp 428. They are used to restrict the movement of the wire clamp when the main scissor assembly 3 and the auxiliary scissor assembly 4 are separated, so as to ensure that there is space between the wire clamp and the wire hook to facilitate the entry of yarn.

[0059] The following uses the fingertips of a knitted glove as an example to illustrate a method for cutting and clamping threads according to the present invention. The steps are as follows:

[0060] (1) Outlining:

[0061] like Figure 10 , Figure 11 , Figure 14 , Figure 17 As described above, when it is necessary to cut the yarn, the first moving motor 21 and the second moving motor 201 are activated, which in turn drive the first main synchronous pulley 22, the first synchronous belt 5, the second main synchronous pulley 202, and the second synchronous belt 50 to move. At the same time, the main scissor assembly 3 and the auxiliary scissor assembly 4 are moved to the position where the yarn needs to be cut. When the first swing motor 11 is activated, it drives the first swing block and the first hook rotating rod 323 to rotate, which in turn drives the first cam connecting rod 321 to move horizontally, and drives the first wire clamp 328 and the first wire hook 327 to move horizontally. The swing block and the first positioning shaft 324 move along the direction of the first clamp guide rail 320. The first hook 327 hooks the yarn. When the first clamp 328 moves, it stops moving after contacting the first scissor baffle 3281. At the same time, the first swing motor 11 is started, and the second swing motor 101 is started to drive the second fork part to move. When the second hook rotating rod 423 rotates, it drives the clamp scissor transmission foot 301 and moves in conjunction with the middle swing rod 302 and the movable scissors 303. At this time, the movable scissors 303 and the fixed scissors 304 are in the open state to complete the hooking of the yarn.

[0062] (2) Cutting the thread:

[0063] like Figure 12 , Figure 15 , Figure 18 As described above, when it is necessary to cut the yarn, after hooking the yarn, the first swing motor 11 and the second swing motor 101 are started. The first hook 327 and the second hook 427 hook the yarn and move it along the first clamp track towards the fixed scissors 304 until the yarn is between the movable scissors 303 and the fixed scissors 304. At the same time, when the second hook rotating rod 423 rotates, it drives the clamp scissors transmission foot 301, which in turn moves the movable scissors 303 to complete the yarn cutting state.

[0064] (3) Loose thread:

[0065] Figure 11 , Figure 16 , Figure 19 As described above, when it is necessary to remove the yarn at the same time, after the yarn is cut, the first swing motor 11 and the second swing motor 101 are started again. The first hook 327 and the second hook 427 hook the yarn and move along the direction of the first clamp track. The first clamp 328 and the second clamp 428 are respectively limited by the first scissor baffle 3281 and the second scissor baffle 4281, so that the cut yarn falls out from the first clamp 328 and the first hook 327, and the second clamp 428 and the second hook 427, respectively.

[0066] like Figure 13 As described above, when it is necessary for the first fork section to untangle the yarn and the second fork section to clamp the yarn, after the yarn is cut, the first swing motor 11 is started, the first hook 327 moves along the direction of the first clamp track, and the first clamp 328 is limited by the first scissor baffle 3281, so that the cut yarn falls out from the first clamp 328 and the first hook 327. The second moving motor 201 is started to drive the auxiliary scissor assembly 4 to move horizontally to the required yarn feeding point, and the second swing motor 101 is started to make the cut yarn fall out from the second clamp 428 and the second hook 427.

[0067] like Figure 13 As described above, when the first fork section needs to clamp the yarn and the second fork section needs to untie the yarn, after the yarn is cut, the first moving motor 21 is started to drive the main scissor assembly 3 to move horizontally to the required yarn feeding point, the first swing motor 11 is started to make the cut yarn fall out from the second clamp 428 and the second hook 427, and the second swing motor 101 is started to make the cut yarn fall out from the first clamp 328 and the first hook 327.

[0068] like Figure 10 As stated above, if there are no other instructions after the yarn is cut, the main scissor assembly 3 or the auxiliary scissor assembly 4 will return to the zero position.

[0069] The yarn clamping and feeding mechanism can hide the yarn ends inside the fabric, enabling the processing of the end yarns, reducing labor costs, and improving the level of automation.

[0070] The above-described specific embodiments are merely preferred embodiments of this invention and are not intended to limit this invention. Any modifications, equivalent substitutions, improvements, etc., made to the washers within the spirit and principles of this invention should be included within the protection scope of this invention.

Driven by the first and second oscillating components, the first and second hooks of the scissor mechanism move downward and hook the yarn; 2. Cut the thread Driven by the first and second oscillating components, the first hook and the first clamp of the scissor mechanism hold one end of the yarn, and the second hook and the second clamp of the scissor mechanism hold the other end of the yarn. Under the control of the scissor control mechanism, the scissor section of the scissor mechanism opens and closes to cut the yarn.

3. Loose threads After the yarn is cut, the first and second clamps hold the two ends of the cut yarn respectively. Then, the first or second clamp is moved laterally to the yarn feeding position. When the horizontal braiding machine is weaving the next section, the yarn is unwound under the drive of the first and second swinging parts.
