Description

Technical Field

[0001] This invention relates to weaving equipment, and more particularly to spindles for weaving equipment. Background Technology

[0002] The weaving material is wound onto the spindle via a wheel. During production, the spindle guides the material onto the weaving device for weaving. After a period of use, the wheel may shift or move, obstructing the material output. Existing equipment uses bolts or other fasteners at the end of the wheel to prevent this shift or movement, but these fasteners make it inconvenient to disassemble and install the wheel. Summary of the Invention

[0003] In view of the above-mentioned problems, the present invention overcomes at least one of the shortcomings by proposing a spindle for weaving equipment.

[0004] The technical solution adopted in this invention is as follows:

[0005] This application provides a spindle for a weaving device, including a spindle seat body and a wheel locking member, wherein a spool is formed on the spindle seat body, and the spool is used to mount a wheel for winding weaving yarn;

[0006] The wheel locking component is disposed on the spool. After the wheel is installed on the spool, the wheel locking component is used to restrict the axial movement of the wheel along the spool.

[0007] The spool is a hollow shaft, and the wheel locking component is an elastic lever. The elastic lever is built into the hollow spool, with one end extending out of the spool and forming a blocking part along the radial direction of the spool. The blocking part has an initial working position and a pressure working position.

[0008] When the blocking part is in the initial working position, the blocking part is used to restrict the axial movement of the wheel;

[0009] When the blocking part is moved, the elastic lever undergoes elastic deformation, and the blocking part moves in the direction of the spool's diameter. The blocking part is in the pressure working position, and the wheel can move along the axial direction of the spool.

[0010] The spindle also includes a first spool assembly, a second spool assembly, and a movable wheel seat.

[0011] The spindle seat body is also provided with a first wheel axle, which is used to install the first thread pulley assembly.

[0012] The movable wheel seat is rotatably mounted on the spindle seat body, and a second wheel axle is formed on the movable wheel seat. The second wheel axle is used to mount the second thread wheel set.

[0013] The spindle also includes a pawl and a second elastic element. The pawl is rotatably mounted on the spindle seat body. The pawl has a claw portion for engaging with a wheel. When the claw portion engages with the wheel, the wheel cannot rotate. One end of the second elastic element is disposed on the spindle seat body, and the other end is connected to the pawl. The second elastic element is used to keep the claw portion and the wheel engaged.

[0014] The movable wheel seat has a contact part. When the movable wheel seat rotates, the contact part abuts against the pawl and overcomes the force of the second elastic element, driving the pawl to rotate and disengage the pawl from the wheel. At this time, the wheel can rotate to realize the output of the braided yarn.

[0015] A first limiting part is formed on the spindle seat body. When the movable wheel seat drives the pawl to rotate, the first limiting part is used to limit the rotation range of the pawl and prevent the second elastic element from failing to work.

[0016] In actual use, the wheel has a plurality of first slots arranged in a circumferential array along the side end face of the wheel, and the first slots are used to engage with the claw.

[0017] In actual use, when the braided thread is pulled away from the wheel, a force is applied to the movable wheel seat away from the wheel. The movable wheel seat rotates, thereby driving the pawl to rotate and disengaging the pawl from the wheel, thus realizing the thread exit. With the spindle exit method provided by this invention, the thread exit rhythm is easy to control and the thread is less prone to tangling.

[0018] The wheel can be easily installed and removed by moving the blocking part or placing the blocking part in the initial working position. When the wheel is installed on the spool, the wheel locking part restricts the axial movement of the wheel along the spool, which can prevent the wheel from shifting or moving and ensure the normal output of the braided thread.

[0019] Furthermore, the end of the elastic paddle furthest from the blocking portion is detachably fixed to the spool by a fastener.

[0020] In actual use, when the elastic lever is damaged, it can be easily disassembled and replaced using fasteners.

[0021] The first spool assembly is rotatably mounted on the first axle, and the second spool assembly is rotatably mounted on the second axle.

[0022] Furthermore, the first axle and the second axle are located on the same side of the spool, and the first axle is located on the side away from the spool.

[0023] Furthermore, the spindle also includes a first guide eye and a second guide eye, which are respectively disposed on the spindle seat body and on the same side of the spool.

[0024] The first guide wire eye is located on the side of the first reel assembly near the spool;

[0025] The second guide eye is located on the side of the first spool assembly away from the spool.

[0026] After the braided thread is pulled out from the wheel, it passes through the first guide eye, and then passes around the first and second spools in sequence, before passing through the second guide eye and being pulled outward.

[0027] In actual use, the braided yarn can be wound onto the first and second spools multiple times in sequence. As the number of turns increases, the tension of the braided yarn also increases.

[0028] Furthermore, the first reel set and / or the second reel set each include at least one reel.

[0029] Furthermore, the spindle also includes a first elastic element and a movable shaft, wherein the first elastic element is disposed on the spindle seat body;

[0030] One end of the movable shaft engages with the first elastic element and is movably mounted on the spindle seat body via the first elastic element;

[0031] The other end of the movable shaft abuts against the movable wheel seat. When the movable wheel seat rotates, the movable shaft is used to reset the movable wheel seat under the action of the first elastic element.

[0032] In actual use, the first elastic element and the movable shaft can be set as an integrated elastic reset component.

[0033] Furthermore, a telescopic channel is formed on the spindle seat body, the movable shaft is disposed in the telescopic channel, the first elastic element is sleeved on the movable shaft, one end of the first elastic element abuts against the end of the telescopic channel, and the other end abuts against the movable shaft. When the movable shaft moves away from the spool along the telescopic channel, the first elastic element undergoes elastic deformation.

[0034] In actual use, the braided yarn is pulled away from the spool, causing the movable wheel to rotate away from the spool, thereby moving the movable shaft away from the spool along the telescopic channel.

[0035] Furthermore, a second limiting portion is formed on the pawl, which is used to limit the rotation range of the movable wheel seat and prevent the movable shaft from disengaging from the telescopic channel and causing it to malfunction.

[0036] Furthermore, the first limiting part and / or the second limiting part are limiting shafts or limiting blocks.

[0037] Furthermore, the pawl is provided with a second slot, and the second elastic element is engaged in the second slot.

[0038] In practical applications, when the movable wheel seat rotates, the second elastic element can be used to reset the pawl.

[0039] The beneficial effects of this invention are:

[0040] (1) The wheel can be easily disassembled and assembled by moving the blocking part or placing the blocking part in the initial working position. After the wheel is installed on the spool, the wheel locking part restricts the axial movement of the wheel along the spool, which can prevent the wheel from deviating or shifting, and ensure the normal output of the braided yarn. With the spindle output provided by the present invention, the output rhythm is easy to control and the yarn is less likely to become tangled.

[0041] (2) When the elastic lever is damaged, it can be disassembled and replaced by fasteners, which is convenient. Attached Figure Description

[0048] The present invention will now be described in detail with reference to the accompanying drawings.

[0049] like Figures 1-4As shown, this application provides a spindle for a weaving device, including a spindle base body 1 and a wheel locking member 2. A bobbin 101 is formed on the spindle base body 1, and the bobbin 101 is used to mount a wheel 3 for winding the weaving thread (the wheel 3 is in...). Figure 3 (The text in the diagram is indicated by dashed lines; the rest is not shown in the diagram).

[0050] The wheel locking component 2 is installed on the spool 101. When the wheel 3 is installed on the spool 101, the wheel locking component 2 is used to restrict the axial movement of the wheel 3 along the spool 101.

[0051] The spool 101 is a hollow shaft, and the wheel locking component 2 is an elastic lever. The elastic lever is built into the hollow spool 101, with one end of the elastic lever extending out of the spool 101 and forming a blocking part along the radial direction of the spool 101. The blocking part has an initial working position and a pressure working position.

[0052] When the blocking part is in the initial working position, the blocking part is used to restrict the axial movement of the wheel 3;

[0053] When the blocking part is moved, the elastic lever undergoes elastic deformation, and the blocking part moves in the direction of the axial diameter of the spool 101. The blocking part is in the pressure working position, and the wheel 3 can move along the axial direction of the spool 101.

[0054] In this embodiment, the spindle also includes a first reel set 4, a second reel set 5, and a movable reel seat 6.

[0055] The spindle seat body 1 is also provided with a first wheel axle 102, which is used to install the first thread pulley set 4.

[0056] The movable wheel seat 6 is rotatably mounted on the spindle seat body 1. A second wheel shaft 61 is formed on the movable wheel seat 6. The second wheel shaft 61 is used to mount the second thread wheel set 5.

[0057] In this embodiment, the spindle also includes a pawl 11 and a second elastic element 12. The pawl 11 is rotatably mounted on the spindle seat body 1. The pawl 11 has a claw portion for engaging with the wheel 3. When the claw portion engages with the wheel 3, the wheel 3 cannot rotate. One end of the second elastic element 12 is disposed on the spindle seat body 1, and the other end is connected to the pawl 11. The second elastic element 12 is used to keep the claw portion and the wheel 3 engaged.

[0058] The movable wheel seat 6 has a contact part 62. When the movable wheel seat 6 rotates, the contact part 62 abuts against the pawl 11 and overcomes the force of the second elastic element 12, driving the pawl 11 to rotate, so that the pawl part is disengaged from the wheel 3. At this time, the wheel 3 can rotate, realizing the output of the braided thread.

[0059] A first limiting part 104 is formed on the spindle seat body 1. When the movable wheel seat 6 drives the pawl 11 to rotate, the first limiting part 104 is used to limit the rotation range of the pawl 11 and prevent the second elastic element 12 from failing to work.

[0060] In actual use, the wheel 3 has a plurality of first slots (not shown in the figure) arranged in a circumferential array along the side end face of the wheel. The first slots are used to cooperate with the claw 113.

[0061] In actual use, when the braided thread is pulled away from the wheel 3, a force is applied to the movable wheel seat 6 in a direction away from the wheel 3. The movable wheel seat 6 rotates, thereby driving the pawl 11 to rotate and disengaging the pawl 113 from the wheel 3, thus realizing the exit of the braided thread. With the spindle exit provided by this invention, the exit rhythm is easy to control and the thread is less prone to tangling.

[0062] The wheel 3 can be easily disassembled and assembled by moving the blocking part or placing the blocking part in the initial working position. When the wheel 3 is installed on the spool 101, the wheel locking part 2 restricts the axial movement of the wheel 3 along the spool 101, which can prevent the wheel 3 from shifting or moving and ensure the normal output of the braided thread.

[0063] In this embodiment, the end of the elastic paddle furthest from the blocking part is detachably fixed to the spool 101 by a fastener.

[0064] In actual use, when the elastic lever is damaged, it can be easily disassembled and replaced using fasteners.

[0065] The first spool set 4 is rotatably mounted on the first axle 102, and the second spool set 5 is rotatably mounted on the second axle 61.

[0066] In this embodiment, the first wheel shaft 102 and the second wheel shaft 61 are disposed on the same side of the spool 101, and the first wheel shaft 102 is disposed on the side away from the spool 101.

[0067] In this embodiment, the spindle further includes a first guide wire eye 7 and a second guide wire eye 8, which are respectively disposed on the spindle seat body 1 and on the same side of the spindle 101.

[0068] The first guide wire eye 7 is located on the side of the first spool 4 near the spool 101;

[0069] The second guide wire eye 8 is located on the side of the first spool 4 away from the spool 101;

[0070] After the braided thread is pulled out from the wheel 3, it passes through the first guide wire eye 7, and then passes through the first thread spool 4 and the second thread spool 5 in sequence, before being pulled outwards after passing through the second guide wire eye 8.

[0071] In actual use, the braided yarn can be wound onto the first spool 4 and the second spool 5 multiple times in sequence. As the number of turns increases, the tension of the braided yarn also increases.

[0072] In this embodiment, the first reel group 4 and the second reel group 5 each include three reels, and the three reels are respectively arranged along the axes of the first reel shaft 102 and the second reel shaft 61.

[0073] In this embodiment, the spindle also includes a first elastic element 9 and a movable shaft 10, with the first elastic element 9 disposed on the spindle seat body 1;

[0074] One end of the movable shaft 10 is engaged with the first elastic element 9 and is movably mounted on the spindle seat body 1 through the first elastic element 9;

[0075] The other end of the movable shaft 10 abuts against the movable wheel seat 6. When the movable wheel seat 6 rotates, the movable shaft 10 is used to reset the movable wheel seat 6 under the action of the first elastic element 9.

[0076] In actual use, the first elastic element 9 and the movable shaft 10 can be configured as an integrated elastic reset component.

[0077] In this embodiment, the first elastic element 9 is a spring.

[0078] In this embodiment, a telescopic channel 103 is formed on the spindle seat body 1, and a movable shaft 10 is disposed inside the telescopic channel 103. A first elastic element 9 is sleeved on the movable shaft 10. One end of the first elastic element 9 abuts against the end of the telescopic channel 103, and the other end abuts against the movable shaft 10. When the movable shaft 10 moves along the telescopic channel 103 away from the spool 101, the first elastic element 9 undergoes elastic deformation.

[0079] In actual use, the braided thread is pulled out away from the spool 101, which drives the movable wheel seat 6 to rotate away from the spool 101, thereby causing the movable shaft 10 to move away from the spool 101 along the telescopic channel 103.

[0080] The second elastic element 12 is an elastic bending rod.

[0081] In this embodiment, the pawl 11 is provided with a second slot 111, and the second elastic element 12 is engaged in the second slot 111.

[0082] In practical applications, when the movable wheel seat 6 rotates, the second elastic element 12 can be used to reset the pawl 11.

[0083] In this embodiment, a second limiting part 112 is formed on the pawl 11. The second limiting part 112 is used to limit the rotation range of the movable wheel seat 6 and prevent the movable shaft 10 from disengaging from the telescopic channel 103 and causing it to fail to function.

[0084] In this embodiment, the first limiting part 104 and the second limiting part 112 are limiting shafts.

[0085] In this embodiment, a wheel seat 13 is also included, which is fixed to the spindle seat body 1 by fasteners.
