Description

Technical Field

[0001] The present application relates to the technical field of warping machines, and in particular to a creel for warping machines. Background Art

[0002] Warping machine is a process that winds a certain number of warp yarns in parallel on the warp head according to the specified length and width. During the warping process, the tension of each warp yarn must be basically equal so that it can be evenly distributed on the warp head.

[0003] Reference Figure 1 The creel comprises a plurality of parallel columns 1 and a fixing rod 3 fixedly mounted on the column 1. The fixing rod 3 is used for installing a yarn drum 30. After the yarn drum 30 is installed on the creel, in order to make the tension of each warp yarn basically equal when feeding the yarn, a tensioner 4 for tensioning the warp yarn is generally installed on the creel. A mounting column 2 for installing the tensioner 4 is fixedly mounted on the creel. The number of mounting columns 2 and the number of columns 1 correspond one to one. The tensioner 4 is close to one end of the yarn drum 30. The warp yarn on the yarn drum 30 passes through the tensioner 4. A yarn guide rod 20 is also installed on the side of the creel close to the warping machine. A plurality of yarn guide rods 20 are arranged at intervals along the height direction of the creel. The yarn guide rod 20 is provided with side-by-side yarn threading holes. The warp yarn coming out of the tensioner 4 passes through the yarn threading holes and then enters the warping machine. When the yarn is fed into the yarn rack, the warp yarn comes out of the yarn tube 30 and passes through the tensioner 4 before entering the yarn guide rod 20. The warp yarns of the yarn tube 30 at the same height all enter the same yarn guide rod 20, and multiple warp yarns are distributed side by side on the yarn guide rod 20.

[0004] With respect to the above-mentioned related technologies, if a yarn tube 30 needs to be replaced, the human hand has to pass over multiple warp yarns and the tensioner 4 to take out the yarn tube 30. After replacing the full yarn tube 30, the human hand has to find the previously cut warp yarn and connect it with the new warp yarn. During the yarn renewal process, care must be taken not to touch other warp yarns. Therefore, the human hand has to be raised high and away from the warp yarn during the yarn renewal process, which makes the human hand more laborious. Summary of the invention

[0005] In order to save effort in yarn refilling when replacing yarn bobbins, the present application provides a yarn frame for a warping machine.

[0006] The present application provides a creel for a warping machine, which adopts the following technical solution:

[0007] A yarn frame for a warping machine includes a plurality of upright posts and mounting posts, a fixing rod fixedly mounted on the upright posts, and a tensioner mounted on the mounting posts. The mounting posts are rotatably mounted with a transition rod, the transition rod is located above the tensioner, and the transition rod rotates with the mounting posts as the rotation center. When one end of the transition rod rotates to approach the fixing rod and forms a coaxial relationship with the fixing rod, a positioning assembly for positioning the transition rod is installed on the mounting posts. A fixing portion is also installed on the mounting posts, and the fixing portion is located between the transition rod and the tensioner.

[0008] By adopting the above technical scheme, when replacing the yarn bobbin on the fixed rod, the transition rod can be rotated to make the transition rod coaxial with the fixed rod. When pushing the yarn bobbin outward, the yarn bobbin can slide into the transition rod, and then the transition rod is rotated to make the yarn bobbin located above the tensioner. The warp yarn on the yarn bobbin can be bonded to the bonding portion first, and then one end of the warp yarn is cut off to replace the yarn bobbin. When replacing the full yarn bobbin, the yarn bobbin is first installed on the transition rod so that the yarn bobbin has a temporary place to be placed. The end of the warp yarn previously left can pass over other warp yarns arranged side by side and continue with the new warp yarn. When continuing the yarn, the person then leaves the warp yarn from the fixed portion, rotates the transition rod to make the transition rod coaxial with the fixed rod, and then pushes the yarn bobbin into the fixed rod. The entire operation is not easy to touch other warp yarns that have been worn, which is convenient for people to replace the yarn bobbin and continue the yarn. When continuing the yarn, the two warp yarns are relatively close to the human body, which makes it more labor-saving for people to continue the yarn.

[0009] Optionally, the positioning assembly is a positioning block and a positioning rod slidably mounted on the positioning block, the positioning block is fixedly mounted on the mounting column, the positioning assembly also includes a first elastic member that drives the positioning rod to always have a downward sliding tendency, a swivel is installed on the transition rod, the swivel is rotatably mounted on the mounting column, and the swivel is provided with a positioning groove for the positioning rod to be inserted.

[0010] By adopting the above technical solution, when the transition rod is rotated to be coaxial with the fixed rod, the positioning slot is located below the positioning rod, and the first elastic member drives the positioning rod to slide downward and be inserted into the positioning slot. The transition rod can remain coaxial with the fixed rod, making it convenient for people to push the yarn tube from the transition rod into the fixed rod, and also convenient for the yarn tube in the fixed rod to enter the transition rod. When the transition rod needs to be rotated to be above the tensioner, the positioning rod is pushed upward to leave the slot, and the transition rod can be rotated.

[0011] Optionally, a yarn guide roller for guiding the warp yarn into the tensioner is installed on the column.

[0012] By adopting the above technical solution, the warp yarn first passes through the yarn guide roller and then enters the tensioner.

[0013] Optionally, an abutment roller is mounted on the column, a driving assembly is mounted on the fixed rod to drive the abutment roller to be tangent to the yarn guide roller, the driving assembly includes a driving block and a second elastic member that drives the driving block to always have a tendency to approach the yarn guide roller, the abutment roller and the yarn guide roller abut against each other, a reset member is mounted on the column to drive the abutment roller away from the yarn guide roller, and when the yarn tube (30) is mounted on the fixed rod, the abutment roller leaves the yarn guide roller.

[0014] By adopting the above technical solution, when the yarn bobbin is mounted on the fixed rod, the driving block is located inside the yarn bobbin, so that the second elastic member cannot drive the driving block to abut against the guide roller, the reset member drives the abutment roller away from the yarn guide roller, and the warp yarn can enter the tensioner normally; if the yarn bobbin leaves the fixed rod, the second elastic member drives the abutment roller downward to abut against the yarn guide roller, and the abutment roller presses the warp yarn on the yarn guide roller, so it is not easy to pull back the warp yarn in the tensioner when the yarn bobbin is replaced.

[0015] Optionally, the reset member is a reset spring, a cross bar is installed on the column, one end of the reset spring is fixedly installed on the cross bar, the abutment roller is connected to a connecting rod, and the other end of the reset spring is connected to the connecting rod.

[0016] By adopting the above technical solution, when the driving assembly does not drive the abutting roller downward, the return spring drives the abutting roller and the yarn guide roller to leave a gap.

[0017] Optionally, a retaining ring is installed at one end of the fixing rod close to the tensioner.

[0018] By adopting the above technical solution, the baffle can limit the yarn tube from axially separating from the fixing rod.

[0019] Optionally, the retaining ring is threadedly mounted on the fixing rod.

[0020] By adopting the above technical solution, the baffle can be stably installed on the fixing rod.

[0021] Optionally, a connecting ring is slidably mounted on the outer peripheral side of the retaining ring, an annular groove is formed on the end surface of the connecting ring, and the connecting ring is clamped with the outer wall of the yarn tube through the annular groove.

[0022] By adopting the above technical solution, when the yarn bobbin needs to be disassembled, the connecting ring is clamped on the yarn bobbin, and then the retaining ring is rotated to bring the yarn bobbin away from the fixed rod. The rotating yarn bobbin can release more warp yarns. When the warp yarns are fixed in the fixed part, the warp yarns between the fixed part and the yarn guide roller are in a straight state, and the extra end of the warp yarns is longer, which is convenient for people to continue the yarn.

[0023] Optionally, an arc-shaped spring piece is mounted on the fixing rod, the arc opening of the spring piece faces the fixing rod, and the arc surface of the spring piece abuts against the inner wall of the yarn tube.

[0024] By adopting the above technical solution, the spring sheet can stably mount the yarn tube on the fixing rod.

[0025] Optionally, a ball is rotatably mounted on the spring sheet, and the ball contacts the inner wall of the yarn tube.

[0026] By adopting the above technical solution, when the yarn bobbin rotates with the fixed rod as the rotation center, the friction of the yarn bobbin can be reduced, which makes it convenient for the yarn bobbin to rotate in situ to release the yarn, and also makes it convenient for the yarn bobbin to rotate away from the fixed rod along with the retaining ring.

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

[0028] 1. When replacing the yarn bobbin, the yarn bobbin is installed on the fixed rod because the transition rod is convenient for people to push the yarn bobbin onto the fixed rod;

[0029] 2. When re-spinning, the previously reserved warp yarn is fixed on the fixed part, and the full yarn bobbin can be placed on the transition rod first, and then the new warp yarn is connected with the old warp yarn. The position of re-spinning is closer to people, which is convenient and labor-saving when re-spinning;

[0030] 3. When the yarn bobbin is installed on the fixed rod, the warping machine can normally pull the warp yarn for warping. When the yarn bobbin leaves the fixed rod, the cooperation of the abutment roller and the yarn guide roller presses the warp yarn, so that when the yarn bobbin leaves the fixed rod, the warp yarn in the tensioner will not be pulled back.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 2-9 This application is described in further detail.

[0042] The present application embodiment discloses a creel for a warping machine. Figure 2 and Figure 3 A creel for a warping machine includes a plurality of columns 1 and mounting columns 2. The plurality of columns 1 are arranged in a row, and the mounting columns 2 are also arranged in a row. There is a spacing between the columns 1 and the mounting columns 2, and the columns 1 and the mounting columns 2 correspond one to one. The creel also includes a fixing rod 3 installed on the column 1 and a tensioner 4 installed on the mounting column 2. A plurality of fixing rods 3 are arranged at intervals along the height direction of the column 1, and the fixing rods 3 are used for the sleeve of the yarn supply tube 30. A plurality of tensioners 4 are also arranged at intervals along the height direction of the column 1, and each fixing rod 3 corresponds one to one. A transition rod 5 is rotatably installed on the mounting column 2, and a swivel 51 is fixedly connected to one end of the transition rod 5. The swivel 51 is coaxially rotatably installed on the mounting column 2. A positioning assembly 6 is installed on the mounting column 2. The positioning assembly 6 positions the transition rod 5 so that the transition rod 5 can be rotated to maintain a coaxial relationship with the fixed rod 3. The yarn tube 30 is sleeved on the transition rod 5. When the transition rod 5 and the fixed rod 3 form a coaxial relationship, the yarn tube 30 is pushed into the fixed rod 3, which makes it convenient for people to install the yarn tube 30 on the fixed rod 3.

[0043] Reference Figure 3A fixing part is installed on the mounting column 2, and the fixing part is located between the transition rod 5 and the tensioner 4, and there is a gap between the fixing part and the transition rod 5 and the tensioner 4. The fixing part is two fixing plates 7 that abut against each other. The fixing plate 7 is an arc-shaped structure, and one end of the fixing plate 7 is fixedly installed on the mounting column 2. The arc openings of the two fixing plates 7 face opposite directions, and the arc surface parts of the two fixing plates 7 that contact each other are straightened to be flat. When replacing the yarn tube 30, slide the yarn tube 30 into the transition rod 5, and then rotate the transition rod 5 so that the end of the transition rod 5 away from the swivel 51 is away from the fixing rod 3, and the warp yarn is wound between the parts where the two fixing plates 7 abut against each other. The two fixing plates 7 clamp and fix the warp yarn, and then slide out of the yarn tube 30, and then cut the warp yarn. The full yarn bobbin 30 is slid onto the transition rod 5, and the new warp yarn is connected with the previously retained warp yarn. The position of the yarn continuation is closer to the human body, which makes it easier for people to continue the yarn. After the yarn continuation is completed, the transition rod 5 is rotated to be coaxial with the fixed rod 3, and the yarn bobbin 30 is slid onto the fixed rod 3.

[0044] Reference Figure 4 and Figure 5 The positioning member is a positioning block 61 and a positioning rod 62 slidably mounted on the positioning block 61. The positioning block 61 is fixedly mounted on the mounting column 2. The positioning block 61 is provided with a slide groove for the positioning rod 62 to slide up and down. The positioning assembly 6 also includes a first elastic member that drives the positioning rod 62 to always have a downward sliding tendency. The first elastic member is a first spring 63. One end of the first spring 63 is fixedly mounted on the inner wall of the slide groove, and the other end of the first spring 63 is fixedly mounted on the positioning rod 62. The end of the positioning rod 62 away from the first spring 63 contacts the end surface of the rotating ring 51, and the rotating ring 51 is provided with a positioning groove 52 for the positioning rod 62 to be inserted. When the transition rod 5 rotates to be coaxial with the fixed rod 3, and the end of the transition rod 5 away from the rotating ring 51 is close to the fixed rod 3, the positioning rod 62 is inserted into the positioning groove 52, so that the transition rod 5 can remain coaxial with the fixed rod 3.

[0045] Reference Figure 6 The positioning rod 62 is a cylindrical structure, and a guide portion is provided on the outer peripheral side of the positioning rod 62. The guide portion is distributed in a ring shape, and the diameter of the end of the guide portion close to the first spring 63 is larger than the diameter of the end of the guide portion away from the first spring 63. When the transition rod 5 rotates, the inner wall of the positioning groove 52 of the swivel 51 contacts the guide portion, and the swivel 51 can drive the positioning rod 62 to leave the positioning groove 52.

[0046] A push block 53 is slidably disposed on the transition rod 5 . When the yarn tube 30 is sleeved on the transition rod 5 , a person can push the yarn tube 30 by means of the push block 53 , thereby shortening the distance between the person's hand and the yarn tube 30 .

[0047] Reference Figure 7The fixing rod 3 is provided with an arc-shaped spring piece 31, and a plurality of spring pieces 31 are provided along the axial direction and the axial direction of the fixing rod 3. The arc opening of the spring piece 31 faces the fixing rod 3. When the yarn drum 30 is installed on the fixing rod 3, the arc surface of the spring piece 31 abuts against the inner wall of the yarn drum 30, and the spring piece 31 can make the yarn drum 30 rotate stably on the fixing rod 3. The spring piece 31 is rollingly provided with a ball 32, and the ball 32 is rollingly contacted with the inner wall of the yarn drum 30, so that when the yarn drum 30 is laying the warp yarn, the friction force of the yarn drum 30 when rotating is increased.

[0048] A retaining ring 8 is installed at one end of the fixed rod 3 close to the tensioner 4. The inner circle of the retaining ring 8 is provided with internal threads. The outer wall of one end of the fixed rod 3 is provided with external threads. The retaining ring 8 is threadedly installed on the fixed rod 3. A connecting ring 81 is slidably installed on the outer peripheral side of the retaining ring 8. A guide bar is fixedly connected to the outer wall of the retaining ring 8. The length direction of the guide bar moves along the axial direction of the connecting ring 81. The connecting ring 81 can only move along the axial direction of the retaining ring 8 under the guidance of the guide bar. An annular groove 82 is provided on the end surface of the connecting ring 81. When the connecting ring 81 moves axially along the retaining ring 8 and approaches the yarn tube 30, the connecting ring 81 is clamped with the outer wall of the yarn tube 30 through the annular groove 82, so that the yarn tube 30 is indirectly connected to the retaining ring 8. When the retaining ring 8 is rotated to make the retaining ring 8 leave the fixed rod 3, the retaining ring 8 takes the yarn tube 30 away. The yarn tube 30 rotates away from the fixed rod 3 to release more warp yarns. After the warp yarns are fixed, the remaining warp yarns are longer, which can also make it more convenient for people to connect the yarns.

[0049] Reference Figure 4 A yarn guide roller 9 is installed on the column 1 to guide the warp yarn into the tensioner 4. The yarn guide roller 9 is located below the fixed rod 3 near the end of the column 1. The warp yarn passes through the yarn guide roller 9 and then enters the tensioner 4. An abutment roller 10 is installed on the column 1, and a driving component 11 is installed on the fixed rod 3 to drive the abutment roller 10 to be tangent to the yarn guide roller 9. After the abutment roller 10 is tangent to the yarn guide roller 9, the warp yarn is clamped between the abutment roller 10 and the yarn guide roller 9. When the yarn drum 30 leaves the fixed rod 3, it is not easy for the yarn drum 30 to pull back the warp yarn in the tensioner 4.

[0050] Reference Figure 7The driving assembly 11 includes a driving block 101 and a second elastic member that drives the driving block 101 to always have a tendency to approach the yarn guide roller 9, and the second elastic member is a second spring 102. A mounting block 33 is installed on the fixed rod 3, and a mounting groove for accommodating the driving block 101 and the second spring 102 is provided on the mounting block 33. The second spring 102 has a plurality of parts, and one end of the second spring 102 is fixedly connected to the inner wall of the mounting groove, and the other end of the second spring 102 is fixedly connected to the driving block 101. An inclined surface 1011 is provided at one end of the driving block 101 close to the spring sheet 31. When the yarn drum 30 is installed on the fixed rod 3, the yarn drum 30 drives the driving block 101 back to the mounting groove by sliding contact with the inclined surface 1011, and the second spring 102 is in a squeezed state. The driving block 101 leaves the abutting roller 10, and a reset member for driving the abutting roller 10 away from the yarn guide roller 9 is installed on the column 1.

[0051] Reference Figure 8 When the yarn tube 30 leaves the driving block 101 and the second spring 102 drives the driving block 101 to partially extend out of the mounting groove, part of the inclined surface 1011 is located outside the mounting groove, and the driving block 101 abuts against the abutting roller 10. The abutting roller 10 abuts against the yarn guide roller 9 under the elastic force of the second spring 102, and the abutting roller 10 and the yarn guide roller 9 clamp the warp yarn.

[0052] Reference Figure 8 and Fig. 9 Two cross bars 13 are installed on the column 1, and the yarn guide roller 9 is rotatably installed between the two cross bars 13. The reset member is a reset spring 12, which is vertically arranged, and the lower end of the reset spring 12 is fixedly installed on the cross bar 13. The abutment roller 10 is coaxially fixedly connected with a connecting rod 14, and the other end of the reset spring 12 is fixedly connected to the connecting rod 14. The connecting rod 14 is vertically connected with a guide rod 15, and the guide rod 15 slides up and down on the cross bar 13, and the reset spring 12 is sleeved on the guide rod 15. The elastic performance of the second spring 102 is greater than the elastic performance of the reset spring 12. Only when the driving block 101 leaves the abutment roller 10, the reset spring 12 will drive the abutment roller 10 upward to leave the yarn guide roller 9, and the yarn guide roller 9 can continue to play the role of guiding the warp yarn.

[0053] The implementation principle of a warping machine creel in the embodiment of the present application is as follows:

[0054] When replacing a bobbin 30 on the creel, when the bobbin 30 leaves the fixed rod 3, the warp yarn part is clamped by the yarn guide roller 9 and the abutting roller 10. After the bobbin 30 enters the transition rod 5, a part of the warp yarn is manually clamped into the two fixing plates 7, so that when the bobbin 30 leaves the creel, the bobbin 30 will not pull back the warp yarn in the tensioner 4. When the bobbin 30 rotates to leave the creel, more warp yarn can be released. The warp yarn between the abutting roller 10 and the fixing plate 7 is in a straight state, and the length of the continuous yarn part left after the warp yarn is clamped by the fixing plate 7 is longer.

[0055] When the yarn tube 30 full of yarn is installed, the yarn tube 30 is temporarily sleeved on the transition rod 5 to continue the yarn first. When continuing the yarn, the two warp yarns are connected. The end positions of the two warp yarns are close to the human body, which is convenient for manual operation, so that people are not likely to touch other warp yarns when continuing the yarn, and it can also be more labor-saving. After the yarn is continued, the transition rod 5 is rotated, and the push block 53 is used to push the yarn tube 30 into the fixed rod 3. The yarn tube 30 can also drive the driving block 101 to leave the abutment roller 10 to make the abutment roller 10 leave the yarn guide roller 9. After the yarn tube 30 is completely located on the fixed rod 3, it is turned away from the transition rod 5, and the retaining ring 8 is threadedly installed on the fixed rod 3. Finally, the warp yarn leaves the two fixed plates 7, and the warping machine is turned on to warp the warp yarn.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
