Description

Technical Field

[0001] The invention relates to the technical field of textile processing, in particular to a thread feeding device with a protective function for processing bedding knitwear. Background Art

[0002] Products made from knitwear that have been processed and woven are called textiles. They can be divided into three categories based on their intended use: clothing textiles, decorative textiles, and industrial textiles. Clothing textiles include various textile fabrics for clothing, as well as textile accessories such as sewing thread, elastic bands, collar interlinings, and linings, as well as knitted garments, gloves, socks, and more. Decorative textiles can be divided into indoor, bedding, and outdoor products, including home linens and restaurant and bathroom supplies. Knitwear processing requires a thread feeder to transport the yarn. However, existing thread feeders are prone to slack in some areas, causing the yarn to tangle. Most existing tensioning devices cannot be adjusted to accommodate site changes, which can easily lead to thread breakage. Summary of the Invention

[0003] (1) Technical problems solved In response to the shortcomings of the existing technology, the present invention provides a wire feeding device with a protective function for processing bedding knitwear. It has the advantages of preventing slack and entanglement, and can self-adjust by floating up and down according to the tightness of the knitting thread on a rotating column. It solves the problem that some parts of the existing wire feeding device are prone to slack when transporting the knitting thread, thereby causing the knitting threads to be entangled with each other, and most of the existing tensioning devices cannot be adjusted according to on-site changes, which easily leads to the breakage of the knitting thread.

[0012] (3) Beneficial effects Compared with the prior art, the present invention provides a thread feeding device with a protective function for processing bedding knitwear, which has the following beneficial effects: 1. The thread feeding device with a protective function for processing bedding knitwear winds the knitting threads to be conveyed around each conveying roller one by one for conveying, and at the same time passes the knitting threads around the bottom of the rotating column. Thus, the weight of the rotating column can be used to tighten the knitting threads during the knitting thread conveying process to avoid slack and entanglement. At the same time, the rotating column can float up and down to adjust itself according to the tightness of the knitting threads, thereby avoiding the breakage of the knitting threads. At the same time, when the knitting threads break or a bundle of knitting threads is conveyed, the rotating column loses support and moves downward, which can cause the lifting plate to move downward to trigger two triggers, thereby closing the conveying device and reminding the staff to come and check.

[0013] 2. The wire feeding device with a protective function for processing bedding knitwear can reduce the friction between the two lifting blocks and the two vertical slots through eight small columns and four slides, so that the two lifting blocks can move up and down more smoothly. At the same time, the eight small columns and four slides can be used to limit the lifting blocks to avoid left and right displacement when they move up and down.

[0014] 3. The wire feeding device with a protective function for processing bedding knitwear can facilitate users to place counterweights through each transverse groove, so that different numbers of counterweights can be added according to the strength of the knitting thread, so as to adjust the appropriate weight to adapt to different knitting threads. At the same time, by rotating the two blocking bars on one side, users can install, pull out or place counterweights, which is convenient for users to use.

[0015] 4. The wire feeding device with a protective function for bedding knitwear processing can provide cushioning when the rotating column loses support and falls through a buffer plate and four pressure springs. Since the blocks under the lifting plate can fall with the lifting plate, when the blocks hit the buffer plate, they will be cushioned by the pressure springs, thus preventing the lifting plate from causing damage to the two triggers due to excessive impact force.

[0016] 5. The wire feeding device with a protective function for bedding knitwear processing moves the support frame upward, thereby driving the two connecting strips to move upward and enter the two fixed half frames respectively, and then the two support frames can be installed by connecting the clamping plates to the two notches respectively.

[0017] 6. The wire feeding device with a protective function for processing bedding knitwear can install the support frame by moving it from bottom to top while the knitting thread is being conveyed. Then, after pulling out the fixing rod, the cross bar can be removed, and the knitting thread can be set between the rotating column and the lifting plate. In this way, the support frame can be installed to relieve the slack of the knitting thread when the knitting thread becomes loose during conveyance. BRIEF DESCRIPTION OF THE DRAWINGS

The knitted yarn to be conveyed is transported by winding it one by one on each conveying roller 2, and the knitted yarn is passed around the rotating column 10 at the same time. At the bottom, the weight of the rotating column 10 can be used to tighten the knitting thread during the conveying process to avoid slack and entanglement. At the same time, the rotating column 10 can float up and down to adjust itself according to the tightness of the knitting thread, so as to avoid the knitting thread from breaking. At the same time, when the knitting thread breaks or a bundle of knitting thread is conveyed, the rotating column 10 loses support and moves downward, so that the lifting plate 4 can move downward to trigger the two triggers 7, so that the conveying device can be closed, thereby reminding the staff to come and check. The front and rear inner walls of the two vertical slots 12 are provided with sliding grooves 13, and the front and rear sides of the two lifting blocks 3 are provided with mounting grooves 27. Two small rods 25 are fixedly installed in the four mounting grooves 27, and each small rod 25 is movably sleeved with a small column. 26, each small column 26 is movably connected to each slide groove 13, and the eight small columns 26 cooperate with the four slide grooves 13 to reduce the friction between the two lifting blocks 3 and the two vertical slots 12, so that the two lifting blocks 3 can move up and down more smoothly.

Through each transverse slot 35, it is convenient for the user to place a counterweight block, so that different numbers of counterweight blocks can be added according to the strength of the knitting thread, so as to adjust the appropriate weight to adapt to different knitting threads. At the same time, by rotating the two blocking bars 37 on one side, it is convenient for the user to install, extract or place the counterweight block, so that it is convenient for the user to use. A buffer plate 8 is movably connected to the support frame 5, and four vertical rods 31 are movably passed through the buffer plate 8. A pressure spring 32 is movably sleeved on the four vertical rods 31. The lower end of each pressure spring 32 is fixedly connected to the lower inner wall of the support frame 5, and the upper end of each pressure spring 32 is fixedly connected to the lower side of the buffer plate 8.The buffer plate 8 cooperates with the four pressure springs 32 to buffer the rotation column 10 after it loses its support and falls. Since the block 33 under the lifting plate 4 can fall with the lifting plate 4, when the block 33 hits the buffer plate 8, it will be buffered by the pressure spring 32, so that the lifting plate 4 can avoid the impact of the two triggers 7 on the two triggers 7 being too large and damaged. The front and rear sides of the right wall of the support frame 5 are fixedly installed with connecting strips 29, and the two connecting strips 29 are provided with grooves 30 on the sides away from each other. The two grooves 30 are movably connected with the card plates 28. The left side of the back plate 1 is fixed with two fixed half frames 9. The two connecting strips 29 are movably connected to the two fixed half frames 9 respectively. By moving the support frame 5 upward, the two connecting strips 29 are driven to move upward and enter the two fixed half frames 9 respectively. Then, the card plates 28 are connected to the two grooves 30 respectively, so that the two support frames 5 can be installed. A notch 11 is provided on the upper side of the support frame 5, a circular groove a20 is provided on the cross bar 19, and two connecting blocks 21 are fixedly installed on the cross bar 19. Two circular grooves b22 are provided on the two connecting blocks 21, and the two circular grooves b22 are connected to the circular groove a20. A square groove 23 is provided on the side of the two lifting blocks 3 close to each other, and a through groove 24 is provided on the inner wall of the two square grooves 23 away from each other. A fixing rod 14 is movably connected in the two through grooves 24, and the fixing rod 14 is movably connected to the two circular grooves b22 and the circular groove a20. The two connecting blocks 21 are movably connected to the two square grooves 23 respectively. The left side of the lifting block 3 on the left of the two lifting blocks 3 is fixedly installed with a thread The threaded tube 15 is internally threaded with a screw rod 16, which is fixedly connected to the fixed rod 14. A rotating block 17 is fixedly installed on the left end of the screw rod 16. By moving the support frame 5 from bottom to top, the support frame 5 can be installed during the conveying of the knitting thread. After the fixed rod 14 is pulled out, the cross bar 19 can be removed. The knitting thread can then be set between the rotating column 10 and the lifting plate 4. In this way, the support frame 5 can be installed to relieve the slack of the knitting thread when it becomes loose during the conveying process.

[0023] When in use, the first step is to wrap the knitting thread to be transported around each conveying roller 2 one by one for transport, and at the same time pass the knitting thread around the bottom of the rotating column 10, so that the weight of the rotating column 10 can be used to tighten the knitting thread during the knitting thread transportation process to avoid loosening and entanglement. At the same time, the rotating column 10 can float up and down to adjust itself according to the tightness of the knitting thread, so as to avoid the knitting thread from breaking. At the same time, when the knitting thread breaks or a bundle of knitting thread is transported, the rotating column 10 loses support and moves downward, so that the lifting plate 4 can move downward to trigger the two triggers 7, so that the conveying device can be closed, thereby reminding the staff to come and check.

[0024] Step 2: By using eight small columns 26 in conjunction with four slide grooves 13, the friction between the two lifting blocks 3 and the two vertical grooves 12 can be reduced, so that the two lifting blocks 3 can move up and down more smoothly. At the same time, the eight small columns 26 can be used in conjunction with the four slide grooves 13 to limit the lifting blocks 3 from left and right displacement when moving up and down.

[0025] Step 3: Each transverse groove 35 can be used to facilitate the placement of counterweights by the user, so that different numbers of counterweights can be added according to the strength of the knitting thread, so that the appropriate weight can be adjusted to suit different knitting threads. At the same time, by rotating the two blocking bars 37 on one side, the user can conveniently install, remove or place the counterweights, making it convenient for the user to use.

[0026] Step 4: The buffer plate 8 cooperates with the four pressure springs 32 to provide buffering when the rotating column 10 loses support and falls. Since the block 33 under the lifting plate 4 can fall with the lifting plate 4, when the block 33 hits the buffer plate 8, it will be buffered by the pressure spring 32. This can prevent the lifting plate 4 from causing damage to the two triggers 7 due to excessive impact force on them.

[0027] Step 5: Move the support frame 5 upwards, thereby driving the two connecting bars 29 to move upwards and enter the two fixed half frames 9 respectively, and then connect the clamping plate 28 to the two notches 30 respectively to install the two support frames 5.

[0028] Step 6: By moving the support frame 5 from bottom to top, the support frame 5 can be installed during the transportation of the knitting thread. After pulling out the fixing rod 14, the cross bar 19 can be removed, and then the knitting thread can be set between the rotating column 10 and the lifting plate 4. In this way, the support frame 5 can be installed to relieve the slack of the knitting thread when the knitting thread is loose during transportation.

[0029] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
