Description

Technical Field

[0001] This utility model relates to the field of wool dyeing and finishing technology, and in particular to an auxiliary device for visually inspecting yarn damage. Background Technology

[0002] Yarn processing requires the use of winding machines to wind the yarn. Currently, in the field of yarn physical property testing, especially for wool yarn, the main methods rely on equipment such as yarn strength and elongation testers. These devices obtain quantitative data such as the breaking strength and elongation of the yarn through mechanical testing, and judge whether the absolute strength and other physical properties of the yarn meet the standards based on the data standards.

[0003] However, existing technology and equipment still have the following drawbacks when in use: the testing equipment only displays the final numerical results, which are relatively abstract. The staff cannot intuitively and visually show the specific form and degree of fiber damage (such as breakage, pilling, and shedding) caused by friction, stretching, etc. during the simulated or actual processing of the yarn. Moreover, when problems occur in the subsequent processing of the yarn (such as excessive shedding during weaving), the process adjustments of the preceding processes such as dyeing and spinning lack a simple, intuitive, and visual feedback means to compare the specific impact of different processes on the yarn fiber damage state (shedding). Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an auxiliary device for visually inspecting yarn damage.

[0005] An auxiliary device for visually inspecting yarn damage, installed near the bottom of a winding machine, includes:

[0006] The support frame is fixed to the winding machine by a connecting frame and screws. The support frame is arranged vertically, and multiple sets of mounting seats are movably installed inside the support frame. Each set of mounting seats has a placement groove at its upper end, and a support cylinder is fixedly connected to the center of the upper end of the placement groove. This cylinder is used to insert into the bottom of the yarn bobbin to limit and support the yarn bobbin.

[0007] A protective collection cylinder is snapped onto the upper end of the placement slot. The protective collection cylinder is made of transparent acrylic material. A base plate is fixedly connected to the bottom of the protective collection cylinder. The base plate has a through-hole interface that snaps onto the outside of the support cylinder. A locking block that snaps onto the outside of the support cylinder is fixedly connected to the inner wall of the interface for guiding and positioning purposes.

[0008] As a further improvement to the above solution, the outer wall of the support cylinder is longitudinally provided with an insertion groove extending to the bottom, and the support cylinder is also provided with an arc-shaped rotating groove connected to the bottom of the insertion groove at the position on the outer side of the bottom. After the locking block is movably inserted into the insertion groove, it rotates and engages with the arc-shaped rotating groove.

[0009] As a further improvement to the above solution, a vent is provided horizontally through the bottom of the insertion slot to connect to the inner cavity, and the vent is blocked after the locking block is inserted vertically into the bottom of the insertion slot.

[0010] As a further improvement to the above solution, a cleaning pipe is also provided horizontally at the bottom of the support frame. The upper end of the cleaning pipe is connected to multiple sets of flexible pipes, and the multiple sets of flexible pipes correspond one-to-one with the support cylinders at the upper end of multiple mounting bases. The flexible pipes are longitudinally connected to the inner cavity of the support cylinder.

[0011] As a further improvement to the above solution, one end of the cleaning pipe is sealed, a small vacuum cleaner is fixedly connected to the outer wall of the support frame, and the air inlet of the small vacuum cleaner is connected to the other end of the cleaning pipe.

[0012] As a further improvement to the above solution, the inner wall of the support frame is horizontally fixedly connected with a guide rod, and the mounting seat is horizontally slidably sleeved on the outside of the guide rod. The inner wall of the support frame is also provided with multiple sets of positioning holes, and the outer wall of the mounting seat is fixedly connected with a positioning component that engages with the positioning hole, which is used to adjust and limit the position of the mounting seat.

[0013] As a further improvement to the above solution, the positioning component includes a positioning pin inserted into the positioning hole, and a limiting plate is fixedly connected to the outer wall of the positioning pin. The limiting plate abuts against the outer side of the positioning hole, and the limiting plate is connected to the outer wall of the mounting base by a spring telescopic pin, which is in a spring-extended state by default.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This solution involves installing a lint collection device below the winding machine frame and placing a transparent protective collection tube to collect the lint, thereby quickly assessing the lint situation of the yarn. Compared to the abstract numerical display results of traditional testing equipment, this invention can quickly achieve an intuitive and visual judgment of yarn quality based on the amount of lint.

[0016] Based on this, the present invention can set multiple sets of protective collection cylinders at the bottom of the winding machine, which can intuitively display and compare the specific impact of different processes on the damage state of yarn fibers, thereby clearly and quickly identifying the optimal process scheme with the least damage to yarn fibers, thereby improving the quality and processing performance of the final yarn product.

[0017] Based on this, after the demonstration and judgment are completed, the present invention can quickly extract the lint collected inside, realize rapid cleaning, and facilitate subsequent work. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please combine Figure 1-5 An auxiliary device for visually inspecting yarn damage is installed near the bottom of a winding machine. It includes: a support frame 1, which is fixedly connected to the winding machine via a connecting frame 2 and screws; the support frame 1 extends vertically through the machine, and multiple sets of mounting seats 3 are movably installed inside the support frame 1; each set of mounting seats 3 has a placement groove 4 at its upper end, and a support cylinder 5 is fixedly connected to the center of the upper end of the placement groove 4 for inserting into the bottom of the yarn bobbin to provide limiting support; a protective collection cylinder 6 is snapped onto the upper end of the placement groove 4, the protective collection cylinder 6 being made of transparent acrylic; a base plate 7 is fixedly connected to the bottom of the protective collection cylinder 6, and the base plate 7 has a through-hole interface 8 that snaps onto the outside of the support cylinder 5; a locking block 9 is fixedly connected to the inner wall of the insertion interface 8 that snaps onto the outside of the support cylinder 5 for guiding and positioning; and a longitudinal insertion groove 501 extending to the bottom is provided on the outer wall of the support cylinder 5.

[0030] Example: Based on the above structural setup, when using this device, the protective collection cylinder 6 is pre-assembled into the placement slot 4 at the upper end of the mounting base 3 using a simple longitudinal insertion method. It should be noted that when the protective collection cylinder 6 is inserted, the locking block 9 on the inner wall of the insertion interface 8 inside the base plate 7 needs to be aligned with the insertion slot 501 on the outer side of the support cylinder 5. Then, the protective collection cylinder 6 is inserted longitudinally to complete the assembly. Next, the yarn spool for winding the yarn is inserted into the outer side of the support cylinder 5, and the bottom of the yarn spool is supported on the upper end of the base plate 7. One end of the yarn is connected to the winding roller of the winding machine. The winding machine is started to drive the winding roller to rotate and realize the yarn winding. During this winding process, the yarn will produce lint due to fiber damage caused by friction, stretching, etc. The lint is protected and isolated by the protective collection cylinder 6 and falls into the protective collection cylinder 6 until the winding is completed. At this time, the lint situation inside can be observed through the transparent acrylic protective collection cylinder 6, thus intuitively and visually displaying the degree of fiber damage of the yarn. Of course, during this process, multiple sets of mounting bases 3 and protective collection cylinders 6 can be set up at the same time to perform winding operations on multiple sets of yarns prepared by different processes. Then, the shedding situation inside multiple sets of protective collection cylinders 6 can be observed, the damage degree of yarns prepared by different processes can be judged and compared, and the optimal process can be selected to facilitate subsequent adjustments and optimizations.

[0031] It should be added that the inner wall of the placement groove 4 is equipped with a rubber pad. The rubber pad makes frictional contact with the outer wall of the protective collection cylinder 6, which can increase the stability of its snap-fit ​​placement. In addition, the protective collection cylinder 6 is set at a certain height so that the lint can be effectively collected in it, avoiding the lint from being splashed outside and affecting the subsequent judgment of yarn damage.

[0032] The support cylinder 5 has a longitudinally extending insertion groove 501 on its outer wall, and an arc-shaped rotating groove 502 connected to the bottom of the insertion groove 501 at the outer bottom position of the support cylinder 5. The locking block 9 is movably inserted into the insertion groove 501 and rotates and engages with the arc-shaped rotating groove 502. A vent 503 is transversely provided at the bottom of the insertion groove 501, which connects to the inner cavity. The locking block 9 is longitudinally inserted into the bottom of the insertion groove 501 and blocks the vent 503. A cleaning pipe 10 is also transversely provided at the bottom of the support frame 1. The upper end of the cleaning pipe 10 is connected to multiple sets of flexible pipes 1001, and each set of flexible pipes 1001 corresponds to a support cylinder 5 at the upper end of a set of mounting bases 3. The flexible pipes 1001 are longitudinally connected to the inner cavity of the support cylinder 5. One end of the cleaning pipe 10 is sealed. A small vacuum cleaner 1002 is fixedly connected to the outer wall of the support frame 1, and the air inlet of the small vacuum cleaner 1002 is connected to the other end of the cleaning pipe 10.

[0033] Based on this, when using this application, after judging the state of yarn shedding, the worker removes the yarn bobbin fitted on the outer side of the upper end of the support cylinder 5. At this time, the yarn shedding is still located on the upper end of the bottom plate 7 at the bottom of the protective collection cylinder 6. The worker can rotate the protective collection cylinder 6, which is already fitted on the outer side of the support cylinder 5, along the P direction. At this time, the locking block 9 on the inner wall of the insertion interface 8 on the inner wall of the bottom plate 7 rotates from the bottom of the insertion groove 501 to the arc-shaped rotation groove 502. At this time, the vent 503 is connected to the inner cavity of the protective collection cylinder 6, and thus the air vent 503 is connected to the inner cavity of the protective collection cylinder 6. The mini vacuum cleaner 1002 is started by an external switch. The mini vacuum cleaner 1002 extracts the lint from the inner wall of the protective collection cylinder 6. The lint passes through the air vent 503, the soft pipe 1001, and the cleaning pipe 10 before entering the mini vacuum cleaner 1002 for storage. This allows for rapid cleaning of the lint inside multiple sets of protective collection cylinders 6. After cleaning, the protective collection cylinder 6 is rotated back to its original position. The locking block 9 is then used to lock into the bottom of the insertion slot 501 and seal the air vent 503, facilitating subsequent yarn damage detection.

[0034] It should be added that the small vacuum cleaner 1002 is preferably a car vacuum cleaner, and the brand is not limited. It can be purchased at the appropriate time. It has a small structure and low cost. It can be fixed to the outside of the support frame 1 by bolts or cable ties and connected to the collection pipe 10.

[0035] The inner wall of the support frame 1 is horizontally fixedly connected to a guide rod 101, and the mounting base 3 is horizontally slidably sleeved on the outer side of the guide rod 101. The inner wall of the support frame 1 is also provided with multiple sets of positioning holes 102, and the outer wall of the mounting base 3 is fixedly connected to a positioning component 103 that is engaged with the positioning hole 102, which is used to adjust and limit the position of the mounting base 3. The positioning component 103 includes a positioning pin 104 that is inserted into the positioning hole 102, and a limiting plate 105 is fixedly connected to the outer wall of the positioning pin 104. The limiting plate 105 abuts against the outer side of the positioning hole 102. The limiting plate 105 is connected to the outer wall of the mounting base 3 through a spring telescopic pin 106, and the spring telescopic pin 106 is in a spring-extended state by default.

[0036] Based on this, during use, this application provides multiple sets of mounting seats 3. During setup, the position of the mounting seat 3 can be slidably adjusted and aligned with the position of the winding yarn at the bottom of the winding machine. Specifically, by pressing the spring telescopic pin 106 with the limiting plate 105, the positioning pin 104 is disengaged from the positioning hole 102. Then, the mounting seat 3 can be slid along the guide rail 101 until it is positioned at the position of the winding yarn at the bottom of the winding machine. After releasing the pressure, the limiting plate 105 springs out under the elastic action of the spring telescopic pin 106, causing the positioning pin 104 on the outside of the limiting plate 105 to re-engage in the corresponding positioning hole 102, thus completing the limiting and fixing the mounting seat 3 after adjustment. This facilitates the use of winding machines of different specifications.

[0037] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0038] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
