Description

Technical Field

[0001] This application relates to the field of yarn processing, and in particular to a straight twist warping machine. Background Technology

[0002] Warping is the process of winding a certain number of warp yarns parallel to each other on a warp beam or weaving beam according to a specified length and width. Warped warp yarns are used for sizing and threading. Warping requires that each warp yarn has equal tension, is evenly distributed on the warp beam or weaving beam, and that the arrangement of colored yarns conforms to the process specifications.

[0003] The existing Chinese invention patent with publication number CN114808231A discloses a warping machine that facilitates material discharge. It includes a warping machine body, a take-up roller is provided on the discharge side of the warping machine body, and limit plates are coaxially provided at both ends of the take-up roller. The limit plates are provided with a support mechanism for supporting the take-up roller. A mounting frame is also provided on the unloading side of the warping machine body. A drive motor is provided on the mounting frame, and a transmission mechanism is provided on the mounting frame. The transmission mechanism is used to drively connect the take-up roller and the drive motor.

[0004] Regarding the aforementioned technologies, the inventors believe that yarns usually need to be twisted before warping, but sometimes the twist degree is not high, and using a separate twisting device for twisting is relatively power-consuming. Summary of the Invention

[0005] In order to save energy consumption, this application provides a straight twist warping machine.

[0006] The direct twisting warping machine provided in this application adopts the following technical solution:

[0007] A straight twist warping machine includes a machine body, on which a take-up drum is rotatably mounted. A mounting frame is provided on one side of the machine body in the width direction. A guide platform is slidably provided on the mounting frame along the length direction of the machine body. A yarn threading hole is provided through the guide platform. A twisting ring is rotatably provided on the guide platform on the side through which the yarn threading hole passes. A twisting hole is provided in the middle of the twisting ring.

[0008] By adopting the above technical solution, during warping, the yarn is evenly wound onto the take-up drum by the sliding of the guide table. During this process, the yarn passes through the twisting hole, and the rotation of the twisting ring can twist the yarn at the same time as warping. When the twisting degree requirement is not high, there is no need to set up a separate twisting device, thus saving energy.

[0009] Optionally, the guide platform is rotatably provided with a yarn-pairing ring on the side opposite to the twisting ring, and the yarn-pairing ring is provided with a plurality of yarn-pairing holes.

[0010] By adopting the above technical solution, the setting of the yarn doubling ring can be used to doubling the yarn at the same time as warping and twisting, thereby improving production efficiency and saving energy.

[0011] Optionally, the mounting bracket is provided with a drive groove, which is opened along the length of the machine body. A drive block is slidably arranged in the drive groove. The drive block is fixed on the guide platform. A drive motor is mounted on the mounting bracket. A drive screw is mounted on the shaft of the drive motor. The drive screw is rotatably arranged in the drive groove. The drive screw passes through the drive block and is threadedly connected to the drive block.

[0012] By adopting the above technical solution, the drive motor drives the drive screw to rotate, and the drive screw, in conjunction with the drive block, drives the guide table to slide in the length direction of the machine body.

[0013] Optionally, a linkage component is provided between the twisting ring and the doubling ring and the mounting frame. The linkage component includes a linkage gear ring and a linkage rack. The linkage gear ring is sleeved and fixed outside the twisting ring or the doubling ring. The linkage rack is installed on the mounting frame along the length of the machine body. The linkage rack and the linkage gear ring mesh with each other.

[0014] By adopting the above technical solution and setting the linkage components, the twisting ring and the yarn doubling ring can rotate synchronously while the drive table slides, without the need for an additional power source, thus saving energy.

[0015] Optionally, the linkage rack includes an upper rack and a lower rack, both of which are slidably mounted on the mounting bracket. The upper rack and the lower rack are slidably mounted so that one of them engages with the linkage gear ring while the other disengages from the linkage gear ring.

[0016] By adopting the above technical solution, since the guide table needs to slide back and forth, the drive of the single rack will cause the twisting ring and the doubling ring to rotate in opposite directions, resulting in the doubling and twisting directions alternating. By using the upper rack and the lower rack interchangeably, the twisting ring and the doubling ring can rotate continuously in one direction when the guide table reciprocates, thereby reducing the probability of the doubling and twisting directions alternating.

[0017] Optionally, the mounting bracket is provided with a drive assembly that drives the upper and lower racks to slide.

[0018] By adopting the above technical solution, the drive component can drive the upper and lower racks to slide, thereby selecting the rack that meshes with the linkage gear ring according to actual needs.

[0019] Optionally, the drive assembly includes a linkage rod, a drive switch, and a drive component. The linkage rod is fixed between the upper rack and the lower rack and connects the upper rack and the lower rack. There are two drive switches, which are respectively mounted on the mounting frame on both sides of the guide table. There are several drive components, all of which are mounted on the mounting frame. The drive components drive the linkage rack to slide.

[0020] By adopting the above technical solution, the drive switch is installed on both sides of the guide table. The drive component is activated by sliding the guide table and pressing the drive switch, thereby realizing the sliding adjustment of the upper and lower racks.

[0021] Optionally, the drive assembly includes a linkage rod, a drive rod, and wedge blocks. There are two linkage rods, which are fixed at both ends of the upper rack along its length and between the upper and lower racks, respectively. The linkage rods connect the upper and lower racks and have wedge grooves on them. The wedge grooves on the two linkage rods face opposite directions. There are two drive rods, which are slidably mounted on the mounting bracket on both sides of the guide platform. The guide platform slides and impacts the drive rods, causing them to slide. There are two wedge blocks, which are fixed on the side of the two drive rods away from the guide platform and are adapted to the wedge grooves.

[0022] By adopting the above technical solution, the guide table slides and impacts the drive rod to drive the drive rod to slide, and the wedge block cooperates with the wedge surface to realize the lifting and lowering of the linkage rod, thereby realizing the sliding adjustment of the upper rack and lower rack.

[0023] Optionally, a clamping member is provided between the machine body and the take-up drum. There are two clamping members respectively provided on both sides of the length direction of the take-up drum. The clamping members are rotatably mounted on the machine body and slide on the machine body in the direction of approaching or moving away from the take-up drum.

[0024] By adopting the above technical solution, the clamping device can clamp and rotate the take-up drum, thereby facilitating the rotation of the take-up drum and making it easy to replace the take-up drum.

[0025] Optionally, a lifting assembly is provided below the take-up drum. The lifting assembly includes a lifting plate and a lifting cylinder. The lifting plate is slidably disposed on the machine body below the take-up drum. The lifting cylinder is installed on the side of the lifting plate away from the take-up drum and drives the lifting plate to slide.

[0026] By adopting the above technical solution, the lifting component facilitates the lifting and replacement of the winding drum.

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

[0028] 1. During warping, the yarn is evenly wound onto the take-up drum by the sliding of the guide table. During this process, the yarn passes through the twisting hole. The rotation of the twisting ring can twist the yarn at the same time as warping. When the twisting degree requirement is not high, there is no need to set up a separate twisting device, which saves energy.

[0029] 2. The setting of the yarn doubling ring can doubling the yarn at the same time as warping and twisting, which improves production efficiency and saves energy;

[0030] 3. The drive motor drives the drive screw to rotate, and the drive screw, in conjunction with the drive block, drives the guide table to slide along the length of the machine body;

[0031] 4. The linkage component is designed so that the twisting ring and the doubling ring rotate synchronously while the drive table slides, without the need for an additional power source, thus saving energy;

[0032] 5. Since the guide table needs to slide back and forth, the drive of the single rack will cause the twisting ring and the doubling ring to rotate in opposite directions, resulting in the doubling and twisting directions alternating. By using the upper and lower racks interchangeably, the twisting ring and the doubling ring can rotate continuously in one direction when the guide table reciprocates, thereby reducing the probability of the doubling and twisting directions alternating.

[0033] 6. The clamping mechanism is designed to clamp and rotate the take-up drum, which facilitates driving the rotation of the take-up drum and also makes it easy to replace the take-up drum.

[0034] 7. The lifting component facilitates the lifting and replacement of the winding drum. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0041] Example 1:

[0042] This application discloses a straight twist warping machine, referring to... Figure 1 The machine includes a main body 1, on which a take-up drum 2 is rotatably mounted. A mounting frame 3 is fixedly mounted on one side of the main body 1 in the width direction. The mounting frame 3 is generally rectangular, with both ends fixedly mounted on the mounting frame 3 in the length direction. A sliding groove 19 is opened on the mounting frame 3 along its length direction. A guide platform 4 is slidably arranged in the sliding groove 19. The guide platform 4 is a rectangular block with a yarn-threading hole 5 through it, facing the take-up drum 2. A twisting ring 6 is rotatably arranged on the guide platform 4 on the side through which the yarn-threading hole 5 passes. The twisting ring 6 is located on the side of the guide platform facing the take-up drum 2, and a twisting hole 7 is provided in the middle of the twisting ring 6. During warping, the yarn is evenly wound onto the take-up drum 2 through the sliding of the guide platform 4 for warping. During this process, the yarn passes through the twisting hole 7. The rotation of the twisting ring 6 can twist the yarn at the same time as warping. When the twisting degree requirement is not high, there is no need to set up a separate twisting device, thus saving energy.

[0043] Reference Figure 2 The guide table 4 is rotatably mounted on the side opposite to the twisting ring 6, and the yarn doubling ring 8 is provided inside the yarn doubling ring 8. The yarn doubling ring 8 can doubling the yarn at the same time as warping and twisting, which improves production efficiency and saves energy.

[0044] Reference Figure 1 and Figure 2The inner wall of the sliding groove 19 of the mounting bracket 3 is provided with a drive groove 10. There are two drive grooves 10, which are respectively opened at the upper and lower ends of the guide table 4 on the inner wall of the sliding groove 19. The drive grooves 10 are opened along the length of the machine body 1. A drive block 11 is slidably arranged in the drive groove 10 and fixed on the guide table 4. A drive motor 12 is installed on the mounting bracket 3. A drive screw 13 is installed on the shaft of the drive motor 12. The drive screw 13 is rotatably arranged in the drive groove 10 above the guide table 4. The drive screw 13 passes through the drive block 11 and is threadedly connected to the drive block 11. The drive motor 12 drives the drive screw 13 to rotate. The drive screw 13, together with the drive block 11, drives the guide table 4 to slide along the length of the machine body 1. The drive screw 13 is a reciprocating screw. The reciprocating screw can realize the reciprocating motion of the guide table 4 without changing the direction of the drive motor 12.

[0045] Reference Figure 1 and Figure 2 A linkage assembly 14 is provided between the twisting ring 6 and the doubling ring 8 and the mounting frame 3. The linkage assembly 14 includes a linkage gear ring 141 and a linkage rack 142. The linkage gear rings 141 of the two sets of linkage assemblies 14 are respectively sleeved and fixed outside the twisting ring 6 and the doubling ring 8. The linkage rack 142 is installed on the mounting frame 3 along the length direction of the machine body 1. The linkage rack 142 and the linkage gear ring 141 mesh with each other. The linkage rack 142 includes an upper rack 1421 and a lower rack 1422. The upper rack 1421 and the lower rack 1422 are slidably disposed on the mounting frame 3. When the upper rack 1421 meshes with the linkage gear ring 141, the lower rack 1422 and the linkage gear ring 141 mesh with each other. When the upper rack 1422 and the linkage gear ring 141 are engaged, the lower rack 1421 and the linkage gear ring 141 disengage. The linkage component 14 allows the twisting ring 6 and the doubling ring 8 to rotate synchronously while the drive table slides, without the need for an additional power source, thus saving energy. Since the guide table 4 needs to slide back and forth, the drive of a single rack will cause the twisting ring 6 and the doubling ring 8 to rotate in both directions, resulting in alternating directions of doubling and twisting. By using the upper rack 1421 and the lower rack 1422 interchangeably, the twisting ring 6 and the doubling ring 8 can rotate continuously in one direction when the guide table 4 reciprocates, thereby reducing the probability of alternating directions of doubling and twisting.

[0046] Reference Figure 1 and Figure 2A drive assembly 15 is provided on the mounting frame 3. The drive assembly 15 drives the upper rack 1421 and the lower rack 1422 to slide. The drive assembly 15 includes a linkage rod 151 fixed between the upper rack 1421 and the lower rack 1422, two drive switches 152 respectively mounted on the mounting frame 3 on both sides of the guide platform 4, and several drive components 153 all mounted on the mounting frame 3. The linkage rod 151 connects the upper rack 1421 and the lower rack 1422. In this embodiment, four drive components 153 are provided. Each of the four drive cylinders is installed on the mounting bracket 3 at both ends of the length direction near the mounting bracket 3. In this embodiment, the drive component 153 is a drive electric cylinder. The four drive electric cylinders are respectively connected to both ends of the length direction of the lower rack 1422 of the two sets of linkage components 14. The two drive switches 152 control the extension and retraction of the piston rod of the drive electric cylinder. When the guide table 4 slides back and forth, it will abut against the drive switch 152, thereby adjusting the rack meshing with the linkage gear ring 141, thereby realizing the switching of the upper rack 1421 and the lower rack 1422.

[0047] Reference Figure 1 and Figure 2 A clamping member 17 is provided between the machine body 1 and the take-up drum 2. There are two clamping members 17, which are respectively located on both sides of the length direction of the take-up drum 2. The clamping members 17 slide and rotate on the machine body 1 via an electric cylinder and a motor. The clamping member 17 is generally shaped like a frustum of a cone. One of the smaller circular ends of the clamping member 17 slides into the take-up drum 2 to clamp the take-up drum 2 and drive the take-up drum 2 to rotate. The frustum of a cone shaped clamping member 17 can be used for take-up drums 2 with different apertures. A lifting assembly 18 is provided below the take-up drum 2. The lifting assembly 18 includes a lifting plate 181 and a lifting cylinder 182. The lifting plate 181 is slidably mounted on the machine body 1 below the take-up drum 2. 182 is installed on the side of the lifting plate 181 away from the take-up drum 2. The lifting cylinder 182 drives the lifting plate 181 to slide. When the take-up drum 2 needs to be installed, the take-up drum 2 is placed on the lifting plate 181 and lifted to the clamping member 17 by the lifting assembly 18. The clamping member 17 clamps and fixes the take-up drum 2. Then the lifting plate 181 is removed from the take-up drum 2. The truncated cone-shaped clamping member 17 can also adjust the position of the take-up drum 2 when fixing it. When the take-up drum 2 needs to be removed, the lifting plate 181 is pressed against the bottom of the take-up drum 2. Then the clamping member 17 is removed from the take-up drum 2 and the take-up drum 2 is removed by the descent of the lifting plate 181.

[0048] The implementation principle of this application embodiment is as follows: The take-up drum 2 is installed on the machine body 1. Then, the yarn that needs to be twisted and combined is passed through the twisting hole 9 and the twisting hole 7 in sequence, and then fixed on the take-up drum 2. The take-up drum is rotated, and at the same time, the guide table 4 is driven to slide back and forth on the mounting frame 3. The guide table 4 guides the yarn to be twisted first by the rotation of the twisting ring 8 before warping and winding on the take-up drum 2, and then twisted by the rotation of the twisting ring 6. After warping and winding, the yarn is taken off the take-up drum 2. After warping is completed, the take-up drum 2 is removed to complete the entire warping process.

[0049] Example 2:

[0050] Compared with Embodiment 1, the driving component 15 in this embodiment is different.

[0051] Reference Figure 3 and Figure 4 The drive assembly 15 includes two linkage rods 151 fixed at both ends of the upper rack 1421 and the lower rack 1422 along the length direction of the upper rack 1421, two drive rods 154 slidably mounted on the mounting bracket 3 on both sides of the guide platform 4, and two wedge blocks 155 fixed on the side of the two drive rods 154 facing away from the guide platform 4. The linkage rods 151 connect the upper rack 1421 and the lower rack 1422, and also connect the linkage racks 142 of the two sets of linkage mechanisms. The linkage rods 151 are provided with wedge grooves 16, and the wedge grooves 16 on the two linkage rods 151 face opposite directions. The guide table 4 slides and impacts the drive rod 154, causing the drive rod 154 to slide. The wedge block 155 is adapted to the wedge groove 16. The guide table 4 slides back and forth and abuts the drive rod 154. The drive rod 154 drives the wedge block 155 to cooperate with the wedge groove 16 to drive the upper rack 1421 and the lower rack 1422 to slide, thereby realizing the replacement of the upper rack 1421 and the lower rack 1422 on the linkage gear ring 141. The wedge grooves 16 with opposite directions on both sides realize the effect of opposite driving directions of the drive rods 154 at both ends, thereby ensuring the alternating use of the upper rack 1421 and the lower rack 1422.

[0052] The implementation principle of this application embodiment is as follows: The take-up drum 2 is installed on the machine body 1. Then, the yarn that needs to be twisted and combined is passed through the twisting hole 9 and the twisting hole 7 in sequence, and then fixed on the take-up drum 2. The take-up drum is rotated, and at the same time, the guide table 4 is driven to slide back and forth on the mounting frame 3. The guide table 4 guides the yarn to be twisted first by the rotation of the twisting ring 8 before warping and winding on the take-up drum 2, and then twisted by the rotation of the twisting ring 6. After warping and winding, the yarn is taken off the take-up drum 2. After warping is completed, the take-up drum 2 is removed to complete the entire warping process.

[0053] The above are all 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.
