Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a quick-change yarn adhesive device. Background Technology

[0002] In the textile spinning industry, there are two main types of yarn handling equipment in the doffing stage: one is the traditional yarn winder, which requires manual cleaning of the tail yarn after doffing. Although the production cost is low, the frequent manual cleaning not only consumes manpower and time, but also leads to high maintenance costs in the later stage; the other is the existing yarn clamp, which theoretically avoids the trouble of manually cleaning the tail yarn. However, it has high requirements for the precision of the doffing process and the adaptability to the spinning variety. Not only is its own production cost high, but the regular professional maintenance of the yarn clamp also makes the maintenance cost difficult to control. Therefore, there is an urgent need for a yarn clamp that can be quickly replaced. Utility Model Content

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-4 As shown, the specific embodiment adopts the following technical solution: it includes a spindle 1 and an inner ring support 2, with the inner ring support 2 sleeved on the spindle 1;

[0025] It also includes:

[0026] The yarn-adhesive ring 3 is sleeved on the inner ring support 2. Several strip grooves 4 with equal rounded corners are opened on the outer ring wall of the inner ring support 2. Positioning strips 5 are fixedly provided on both the left and right sides of the inner wall of the yarn-adhesive ring 3, and the positioning strips 5 are movably abutting against the strip grooves 4.

[0027] The annular blade 6 is abutted against the upper part of the inner ring support 2. The upper part of the inner ring support 2 is fitted with a pressure cap 7, which abuts against the upper part of the annular blade 6. The inner ring support 2 is provided with a convenient disassembly mechanism 8 that cooperates with the pressure cap 7. A retaining ring 17 is fitted on the inner ring support 2, and the bottom of the retaining ring 17 abuts against the spindle 1. The yarn-adhesive ring 3 abuts against the upper part of the retaining ring 17. The physical obstruction of the retaining ring 17 can restrict the movement path of the yarn and prevent the yarn from getting tangled in the non-working area during the doffing process. The outer ring wall of the pressure cap 7 and the inner ring wall of the retaining ring 17 are provided with ribs 18. The inner and outer sides of the inner ring support 2 are provided with stop grooves 19 that cooperate with the ribs 18. The ribs 18 and the stop grooves 19 can be interlocked in the cooperation between the inner ring support 2, the pressure cap 7, and the retaining ring 17 to prevent the pressure cap 7 and the retaining ring 17 from sliding or falling off on the inner ring support 2.

[0028] Check ring 9, the check ring 9 is abutted in the annular groove 10 opened on the inner ring wall of the inner ring support 2, and the check ring 9 is movably sleeved in the annular slot 11 opened on the spindle 1. The spindle 1 is provided with several toothed grooves 12, and the inner ring wall of the inner ring support 2 is fixedly provided with positioning teeth 13 that cooperate with the toothed grooves 12.

[0029] The convenient disassembly mechanism 8 includes:

[0030] Pressing rod 8-1, there are two pressing rods 8-1, which are respectively rotatably disposed in the pressing grooves opened on the left and right sides of the inner ring bracket 2 via a rotating shaft;

[0031] Several push rods 8-2 are movably inserted into several slots 8-3 with rounded corners on the upper part of the inner ring bracket 2. Adjacent push rods 8-2 are connected by connecting rods 8-4. The upper end of the push rod 8-2 abuts against the pressure cap 7. The lower end of each push rod 8-2 on both sides is rotatably equipped with a rotating wheel 14 via a rotating shaft. The rotating wheel 14 is movably abutting against the pressing rod 8-1. The rotation of the rotating wheel 14 can avoid direct friction between the push rod 8-2 and the pressing rod 8-1, thus preventing wear and increasing service life. The lower ends of the remaining push rods 8-2 are fixedly connected to the inner ring bracket. When replacing the annular blade 6, the spring 8-5 connected to the 2 can use the convenient disassembly mechanism 8 to lift the cover 7, improving the ease of replacing the annular blade 6 and avoiding the increased disassembly difficulty due to the contact between the cover 7 and the annular blade 6. The top rod 8-2 is movably fitted with a positioning ring 15, and the positioning ring 15 is fixedly set on the upper part of the inner ring bracket 2. The annular blade 6 is provided with a positioning hole 16 that cooperates with the positioning ring 15. The positioning ring 15 can realize the installation positioning of the annular blade 6, which not only ensures the accurate installation position of the annular blade 6, but also prevents the annular blade 6 from rotating on the inner ring bracket 2.

[0032] When using this invention, the yarn-adhesive ring 3 can directly adhere to the yarn unwound from the spindle during the spinning doffing process, preventing the yarn from slipping or tangling and ensuring the stable completion of the doffing action. After the yarn is adhered, the annular blade 6 works in conjunction with the yarn-adhesive ring 3 to quickly cut the yarn during doffing, forming a clear cut end and avoiding yarn residue that could cause problems in subsequent production. After the yarn is cut, the high-speed rotating spindle uses centrifugal force to throw off the remaining tail yarn. The yarn-adhesive ring 3 ensures that the tail yarn will not re-entangle or adhere to the spindle, eliminating the need for manual cleaning.

[0033] When the annular blade 6 needs to be replaced, press down the pressing rods 8-1 on both sides simultaneously. At this time, one end of the pressing rod 8-1 will tilt upward and push the push rod 8-2 in contact with it upward. At the same time, through the cooperation of the connecting rod 8-4, several push rods 8-2 can move upward simultaneously and stretch the spring 8-5. The push rod 8-2 pushes the pressure cover 7 upward, so that the pressure cover 7 disengages from the interference fit with the inner ring bracket 2 and separates from the annular blade 6. Then the pressure cover 7 can be removed from the inner ring bracket 2, and the annular blade 6 can be replaced.

[0034] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0035] 1. By utilizing the cooperation of the pressing rod 8-1, the top rod 8-2 and the connecting rod 8-4 in the convenient disassembly mechanism 8, the pressure cap 7 can be lifted synchronously at multiple points, so that it can be disengaged from the interference fit of the inner ring bracket 2. The replacement of the ring blade 6 can be completed quickly without the aid of tools, which greatly improves the convenience of maintenance.

[0036] 2. The yarn-adhesive ring 3 and the annular blade 6 work together. When the yarn is unwound, the yarn-adhesive ring 3 can directly adhere to the unwound yarn to prevent slippage. The annular blade 6 quickly cuts the yarn to form a clear end. With the help of the high-speed rotating spindle, the tail yarn is thrown off by centrifugal force. No manual cleaning is required, which effectively reduces labor costs and avoids subsequent production failures.

[0037] 3. The interlocking structure of the rib 18 and the stop groove 19, and the positioning fit of the positioning ring 15 and the positioning hole 16, ensure that the pressure cap 7, the retaining ring 17 and the annular blade 6 do not slip or fall off during high-speed rotation, and ensure the accuracy of the installation position of the annular blade 6.

[0038] 4. The rotating wheel 14 reduces the direct friction between the push rod 8-2 and the pressing rod 8-1, extending the service life of the components and reducing long-term maintenance costs.

[0039] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
