Description

Technical Field

[0001] This utility model relates to the field of yarn feeding technology for yarn doubling machines, and more specifically, to a yarn bobbin feeding structure for yarn doubling machines. Background Technology

[0002] A doubling machine is an important piece of equipment in the textile industry used to combine multiple strands of fine yarn into a single roving. It is commonly used in various fields such as cotton spinning, wool spinning, and silk spinning to enhance the strength and uniformity of the yarn. During the doubling process, the yarn is drawn from multiple original bobbins, passes through a series of yarn guiding devices, and is ultimately combined into a thicker yarn, which is then wound onto a new bobbin.

[0003] After each yarn bobbin on the yarn doubling machine has finished winding yarn, a new bobbin needs to be placed for replacement. Replacing the bobbin manually from the outside is time-consuming and labor-intensive. Currently, many workshops install a feeding box above the yarn doubling machine to store new bobbins for easy replacement. However, when using this method, the feeding box and the inlet are quite high, requiring workers to use ladders or other tools to lower the bobbin from a height. This is inconvenient, requires the use of tools, results in low feeding efficiency, and poses a safety hazard as it increases the risk of workers bumping into each other and falling.

[0004] Therefore, it is necessary to provide a yarn bobbin feeding structure for the yarn doubling machine to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a yarn bobbin feeding structure for a yarn doubling machine to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The yarn bobbin feeding structure of the yarn doubling machine, installed on the yarn doubling machine, includes:

[0008] A feeding box is located above the yarn doubling machine, and a guide chute for the yarn bobbin to pass through is provided in the feeding box;

[0009] A feeding trough plate is rotatably disposed on one side of the feeding box, and a placement box for placing yarn bobbins is slidably disposed inside the feeding trough plate;

[0010] A transmission mechanism is provided on the feeding box and is used to drive the feeding trough plate to rotate;

[0011] The yarn discharge mechanism is located at the discharge point of the feeding box and is used to control the discharge of yarn bobbins from the feeding box.

[0012] Furthermore, a rotating shaft is rotatably provided on the feeding box, and a connecting seat connected to one end of the feeding trough plate is provided in the middle of the rotating shaft.

[0013] Furthermore, the transmission mechanism includes:

[0014] A driving component is disposed on the side wall of the feeding box, and a first gear is provided at the output end of the driving component;

[0015] The outer end of the shaft is provided with a second gear that meshes with the first gear.

[0016] Furthermore, the tube outlet mechanism includes:

[0017] The mounting frame is set on the outer wall of the feeding box. The mounting frame is provided with two first telescopic members. The output end of the first telescopic member is provided with a baffle. The other end of the baffle moves through the feeding box and extends into the guide trough.

[0018] Furthermore, the side wall of the feeding box is also provided with a second telescopic member, the telescopic end of the second telescopic member is provided with a protective block, and the side wall of the feeding trough is provided with a limiting block that cooperates with the protective block.

[0019] Furthermore, the inner wall of the feeding trough plate is provided with a sliding groove, and the outer wall of the placement box is provided with a sliding strip that matches the sliding groove.

[0020] Furthermore, a limiting plate is provided above the material guide trough.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] When new yarn bobbins need to be added to the feeding box, this solution first uses a transmission mechanism to rotate the feeding trough plate to a downward tilting position, allowing the placement box to slide down along the feeding trough plate. At this point, the downward tilting of the feeding trough plate and the placement box will bring them closer to the worker, who can then place the new yarn bobbins into the placement box. The degree to which the placement box slides along the feeding trough plate can be adjusted according to different workers' needs. This eliminates the need for workers to use ladders or other tools, making the operation simple, convenient, time-saving, and labor-saving, greatly improving the efficiency of yarn bobbin feeding. Furthermore, it significantly prevents collisions and falls caused by climbing ladders to feed yarn bobbins, ensuring high safety and practicality.

[0023] After the yarn bobbins are replenished in the placement box, the transmission mechanism drives the feeding trough plate to rotate upwards, causing the feeding trough plate to return to its upward tilted state. After a yarn bobbin falls into the guide trough, a yarn bobbin will enter the guide trough in the placement box, thus realizing the feeding of yarn bobbins. The staff can observe the number of yarn bobbins in the guide trough of the feeding box, which allows for a direct and convenient understanding of the status of yarn bobbins in the placement box of the feeding trough plate. The usage effect is good. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-6 The yarn bobbin feeding structure of the yarn doubling machine, installed on the yarn doubling machine 1, includes:

[0034] The feeding box 2 is located above the yarn winding machine 1, and the feeding box 2 has a guide groove 3 for the yarn bobbin to pass through;

[0035] The feeding trough plate 5 is rotatably set on one side of the feeding box 2, and a placement box 6 for placing yarn tubes is slidably set inside the feeding trough plate 5;

[0036] The transmission mechanism 7 is located on the feeding box 2 and is used to drive the feeding trough plate 5 to rotate;

[0037] The yarn discharge mechanism 8 is located at the discharge point of the feeding box 2 and is used to control the discharge of the yarn bobbins inside the feeding box 2.

[0038] In use, after the yarn bobbins on the yarn winding machine 1 are wound, the new yarn bobbins inside the feeding box 2 are dropped down for subsequent winding operations. When it is necessary to add material to the feeding box 2, that is, when it is necessary to add new yarn bobbins to the feeding box 2, the transmission mechanism 7 can be used to drive the feeding trough plate 5 to rotate, turning the upward-inclined feeding trough plate 5 to a downward-inclined position, and the placement box 6 can slide down along the feeding trough plate 5. Figure 5 In the state shown, the feeding trough 5 and the placement box 6 are tilted downwards and close to the operator. The operator can place the new yarn bobbin into the placement box 6. The operator can add material while standing normally. The placement box 6 can be pulled along the feeding trough 5 to the desired extent according to different people's needs. There is no need for the operator to use ladders or other tools. This not only makes the operation simple and convenient, but also saves time and effort and greatly improves the efficiency of yarn bobbin feeding. It also greatly prevents collisions and falls caused by climbing ladders to feed materials, making it safe and highly practical.

[0039] After replenishing the yarn bobbins in the placement box 6, the placement box 6 is pushed into the feeding trough plate 5, and the feeding trough plate 5 is rotated upwards by the transmission mechanism 7, so that the feeding trough plate 5 returns to its upward tilted state. At this time, the placement box 6 corresponds to the guide trough 3 of the feeding box 2. The yarn bobbins at the outlet of the feeding box 2 can be controlled by the bobbin discharge mechanism 8. After a yarn bobbin falls into the guide trough 3, a yarn bobbin will enter the guide trough 3 in the placement box 6, thus realizing the feeding of yarn bobbins. The operator can observe the number of yarn bobbins in the guide trough 3 of the feeding box 2. When no more yarn bobbins are added to the guide trough 3, it can be known that there are no more yarn bobbins in the placement box 6. At this time, the above-mentioned yarn bobbin replenishment operation can be performed on the placement box 6 of the feeding trough plate 5. The feeding is intuitive and convenient, and the use effect is good.

[0040] For preferred options, please refer to [link / reference]. Figure 2 and Figure 5-6 A limiting plate 4 is provided above the guide trough 3. The limiting plate 4 can restrict the yarn bobbins in the guide trough 3, preventing the yarn bobbins from stacking and rolling and blocking, and ensuring that the yarn bobbins move orderly and neatly in the guide trough 3.

[0041] For preferred options, please refer to [link / reference]. Figure 3 and Figure 5-6 A rotating shaft 9 is rotatably mounted on the feeding box 2, and a connecting seat 10 connected to one end of the feeding trough plate 5 is provided in the middle of the rotating shaft 9.

[0042] With this design, when the transmission mechanism 7 is running, it will drive the rotating shaft 9 to rotate, which in turn will drive the connecting seat 10 to rotate. The connecting seat 10 will then drive the feeding trough plate 5 to rotate around the axis of the rotating shaft 9, thus realizing the downward and upward tilting of the feeding trough plate 5.

[0043] For preferred options, please refer to [link / reference]. Figure 2-3 and Figure 5 The transmission mechanism 7 includes:

[0044] The drive unit 71 is disposed on the side wall of the feeding box 2. The output end of the drive unit 71 is provided with a first gear 72. The drive unit 71 in this application can be a servo motor.

[0045] The outer end of the rotating shaft 9 is provided with a second gear 73 that meshes with the first gear 72.

[0046] Specifically, when the drive unit 71 is running, it will drive the first gear 72 to rotate forward / reverse. The first gear 72 will then drive the second gear 73 and the rotating shaft 9 to rotate in reverse / forward. The rotating shaft 9 will then drive the connecting seat 10 and the feeding trough plate 5 to rotate upward / downward, making it convenient for the staff to replenish materials.

[0047] For preferred options, please refer to [link / reference]. Figure 2 and Figure 4-5 The tube-discharging mechanism 8 includes:

[0048] Mounting frame 81 is set on the outer wall of feeding box 2. Two first telescopic members 82 are provided on mounting frame 81. A baffle 83 is provided at the output end of the first telescopic member 82. The other end of the baffle 83 moves through the feeding box 2 and extends into the guide groove 3. The first telescopic member 82 in this application can be an electric telescopic rod.

[0049] With this design, the yarn bobbins in the guide trough 3 are blocked by baffles 83, and there is also a yarn bobbin between the two baffles 83. When a yarn bobbin needs to fall through the feeding box 2, the first telescopic member 82 at the bottom will cause the lower baffle 83 to retract, meaning the lower baffle 83 will no longer block the bottom of the lowest yarn bobbin. The lowest yarn bobbin (that is, the yarn bobbin between the two baffles 83) will fall from the bottom outlet of the feeding box 2, thus completing the yarn bobbin feeding. After the lowest yarn bobbin falls out, the first telescopic member 82 at the bottom will cause the lower baffle 83 to extend, while the first telescopic member 82 at the top will cause the upper baffle 83 to retract. Then, the yarn bobbin on the upper baffle 83 will fall and be blocked by the lower baffle 83. Then the upper baffle 83 will extend again, meaning that all the yarn bobbins in the guide trough 3 have moved forward by one yarn bobbin. This cycle is repeated, thus realizing the function of continuous automatic feeding of yarn bobbins in the feeding box 2.

[0050] For preferred options, please refer to [link / reference]. Figure 2-3 and Figure 5-6The side wall of the feeding box 2 is also provided with a second telescopic member 11. The telescopic end of the second telescopic member 11 is provided with a protective block 12. The side wall of the feeding trough plate 5 is provided with a limiting block 13 that cooperates with the protective block 12. The second telescopic member 11 in this application can be an electric telescopic rod.

[0051] With this design, when the transmission mechanism 7 drives the feeding trough plate 5 to rotate to an upward tilting state, the second telescopic member 11 will cause the protective block 12 to extend, moving it to the position of the limiting block 13. The protective block 12 can block the limiting block 13 and the feeding trough plate 5, preventing the feeding trough plate 5 from rotating downward and falling due to subsequent malfunctions. This not only protects the feeding trough plate 5 and reduces its damage, but also greatly protects the safety of the workers, providing excellent protection. When the transmission mechanism 7 needs to drive the feeding trough plate 5 to rotate downward and tilt, the second telescopic member 11 will first drive the protective block 12 to retract, so that the protective block 12 no longer interferes with the limiting block 13, and the feeding trough plate 5 can then rotate and tilt.

[0052] For preferred options, please refer to [link / reference]. Figure 2 and Figure 5 The inner sidewall of the feeding trough plate 5 is provided with a sliding groove 14, and the outer sidewall of the placement box 6 is provided with a sliding strip 15 that matches the sliding groove 14. When the placement box 6 is slid along the feeding trough plate 5, the sliding strip 15 of the placement box 6 will slide along the sliding groove 14, which can improve the stability and smoothness of the sliding of the placement box 6, and also prevent the placement box 6 from falling out of the feeding trough plate 5, resulting in good performance.
