Description

Technical Field

[0001] This application relates to the field of single-sided yarn frame technology, and in particular to a single-sided yarn frame that is easy to transport and install. Background Technology

[0002] Yarn rigs are important supporting equipment in the production process of single-jersey knitting machines. Their core function is to adapt to the yarn demand of single-jersey machines of different specifications and the workshop installation space. According to the knitting production process requirements, they orderly carry multiple sets of yarn rolls of different specifications, and continuously and stably supply yarn that meets the production standards to the knitting mechanism of the single-jersey machine.

[0003] The existing technology has the following problems: The yarn frame that is matched with the small and medium-sized single-face machine under the existing technology mostly adopts an integrated structure design. This type of yarn frame is formed as a whole after the production and manufacturing is completed. Its overall installation weight is large, and it usually requires the cooperation of multiple workers to complete the handling and installation operations. Furthermore, the large size of the integrated yarn frame occupies a lot of transportation space during transport, which limits the number that can be transported at one time and increases transportation costs. At the same time, due to its large size and fixed structure, it is difficult to flexibly adjust the installation position during installation. Especially in the case of a relatively small workshop space, the difficulty of installation operation for workers is significantly increased, which seriously affects the installation efficiency of the yarn frame occupies. Utility Model Content

[0004] The purpose of this invention is to provide a single-sided yarn frame that is easy to transport and install in order to solve the above-mentioned problems.

[0005] The technical solution of this application is implemented as follows: This application provides a single-sided yarn frame that is easy to transport and install, including a mounting plate. A telescopic column is fixedly installed on the top of the mounting plate. Four sets of folding frames are evenly distributed around the outer top of the telescopic column. A mounting ring is fixedly installed on the inner side of the folding frames. The folding frame includes a connecting plate, which is fixedly installed on the outer top of the telescopic column. A support frame is integrally formed on the side of the connecting plate away from the telescopic column. Mounting frames are detachably hinged to the top of the left and right sides of the support frame through fixing pins. Several sets of first mounting holes are opened on the top of the mounting frame. Mounting rings are detachably fixedly installed on the mounting frame through the first mounting holes. A locking hole is opened on the bottom of the side of the support frame away from the connecting plate.

[0006] In one embodiment, when the fixing pin is loosened, the mounting bracket can rotate around the hinge point to the side of the support frame away from the connecting plate and be sleeved on the outside of the support frame. At this time, the first mounting hole farthest from the connecting plate is coaxially corresponding to the lock hole, and the mounting bracket can be folded and locked by passing a lock through the lock hole.

[0007] In one embodiment, the support frame has symmetrically and detachably connected reinforcing ribs at the center of the left and right sides, and the end of the reinforcing rib away from the support frame is detachably connected to the center of the left and right sides of the mounting frame to form a triangular support structure.

[0008] In one embodiment, the mounting bracket has several sets of locking holes extending through the left and right sides of its front end. Locking pins are detachably embedded in the locking holes. When the mounting bracket is unfolded, a connecting pin for extending the installation radius is detachably embedded in the bottom of the mounting bracket through the locking holes and locking pins. The mounting bracket can adjust the embedding depth of the connecting pins through the locking holes and locking pins to adapt to mounting rings of different specifications.

[0009] In one embodiment, the connecting post includes a square steel bar with a second mounting hole at the top for mounting ring assembly. The left side of the square steel bar has a plurality of adjustment holes adapted to the locking hole. When the square steel bar is embedded in the bottom of the mounting frame, one set of adjustment holes is aligned with the locking hole, and the square steel bar is fixed by the locking post being embedded inside the two. Then, the mounting ring is installed by adapting to the second mounting hole.

[0010] In one embodiment, the support frame includes an outer frame and an inner frame. A connecting plate is circumferentially fixedly installed on the top outer side of the outer frame, and the bottom of the inner frame is fixedly installed on the top of the mounting plate. A first embedding hole is provided on the bottom outer side of the outer frame. The top of the inner frame is slidably embedded into the interior of the outer frame, and a second embedding hole adapted to the first embedding hole is provided on its bottom outer side. Pins are embedded in the first and second embedding holes, and the outer frame and the inner frame are fixed by the pins, thereby adjusting the overall length of the support frame.

[0011] In one embodiment, the mounting bracket is made of aluminum alloy.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following: This application presents a single-sided yarn frame that is easy to transport and install. The frame is designed to be foldable by rotating and folding around the support frame and locking it through the first mounting hole and the locking hole. Combined with the detachable structure of the mounting column, mounting ring and reinforcing rib, it enables a single person to complete the handling of parts and the overall installation without the need for multiple workers, which greatly reduces the manpower requirement and labor cost. During storage and transportation, the support frame is pushed into the outer frame through the inner frame to shorten the longitudinal length. The four sets of mounting frames are folded and fitted on the outside of the support frame to reduce the lateral dimension. The mounting columns, mounting rings, and reinforcing ribs can be disassembled and stored independently, which significantly reduces the overall volume compared to the existing integrated yarn frame. This not only optimizes the storage convenience when the workshop is idle, but also increases the quantity transported in a single trip and reduces the unit transportation cost and logistics energy consumption. In addition, the mounting column can flexibly adjust the radius of the mounting ring through the adjustment hole and locking hole to adapt to different yarn feeding requirements. The triangular support structure with reinforcing ribs can distribute the load and prevent the mounting frame from deforming, thus balancing flexibility and stability. Attached Figure Description

[0021] Reference Figure 1 A single-facer yarn frame that is easy to transport and install includes a mounting plate 1, which serves as the bottom support for the entire yarn frame, bearing the weight of the telescopic column 2, the folding frame 3, and the yarn roll, and fixing it to the top of the single-facer. In this embodiment, the mounting plate 1 is a flange with 6 waist-shaped mounting holes, which are aligned with the positioning holes reserved at the top of the single-facer main frame. High-strength hexagonal bolts are passed through the waist-shaped holes of the mounting plate 1 and screwed into the positioning holes of the frame to complete the fixation.

[0022] The top of the mounting plate 1 is fixedly equipped with a telescopic column 2. The telescopic column 2 can adjust the overall height of the yarn rack according to the actual situation to ensure that the yarn enters the single-face machine at a suitable angle. During transportation, the telescopic column 2 can be retracted to its shortest length, which greatly reduces the longitudinal space occupied by the yarn rack and facilitates loading and handling.

[0023] Four sets of folding frames 3 are evenly distributed around the top of the outer side of the telescopic column 2. The folding frames 3 can be unfolded or folded according to the usage. When the folding frames 3 are unfolded, the mounting ring 4 can be installed and its weight supported. The four sets of layout can evenly distribute the weight and prevent the center of gravity of the yarn frame from shifting. When transported or not in use, the folding frame 3 can be folded and stowed to reduce the lateral volume of the yarn rack, making it easy for a single person to handle or for workshop storage.

[0024] The inner side of the folding frame 3 is fixedly equipped with an installation ring 4. The installation ring 4 is used to install and fix the yarn feeder. It should be noted that the specific fixing method and principle of the yarn feeder are existing technologies, so they will not be described in detail.

[0025] In one embodiment, reference is made to Figure 2 The folding frame 3 includes a connecting plate 31, which is fixedly installed on the outer top circumferential direction of the telescopic column 2. The connecting plate 31 is used to connect the folding frame 3 and the telescopic column 2, and the support frame 32 provides a stable installation reference.

[0026] A support frame 32 is integrally formed on the side of the connecting plate 31 away from the telescopic column 2. The support frame 32 has better rigid support performance because it is integrally formed with the connecting plate 31. The support frame 32 is used to provide a stable support for the mounting frame 33, ensuring that the mounting frame can bear the weight of the mounting ring 4 and the yarn feeder after it is unfolded, and to avoid deformation due to stress. Furthermore, the support frame 32 can provide a rotation reference for the folding of the mounting frame 33, limiting the folding direction and angle of the mounting frame 33, ensuring that the mounting frame 33 can be accurately fitted onto its outer side when folded, reducing the space occupied after folding.

[0027] Mounting brackets 33 are detachably hinged to the top of the left and right sides of the support frame 32 via fixing pins. Mounting brackets 33 provide installation space for mounting rings 4. At the same time, as a foldable component, mounting brackets 33 can shrink in lateral volume by rotating around the support frame 32, which is convenient for single-person handling or workshop stacking.

[0028] When the mounting bracket 33 needs to be unfolded, the fixing pin passes through the hinge hole of the support bracket 32 ​​and the mounting bracket 33 to securely connect the two, ensuring that the mounting bracket 33 can bear the weight of the subsequent components and preventing the mounting bracket 33 from rotating unexpectedly during use. When transportation or when not in use, the rigid connection between the two can be released by loosening the fixing pin, allowing the mounting bracket 33 to rotate and fold around the hinge point without disassembling the entire mounting bracket 33, greatly simplifying the folding operation process. To ensure that the hinge point between the support frame 32 and the mounting frame 33 will not break due to the load or frequent folding, the hinge part at the top of the support frame 32 adopts a thickened ear plate design, with the ear plate being 1.5 times thicker than the main body of the support frame. At the same time, a reinforcing boss is added to the hinge end of the mounting frame 33 that mates with the ear plate to increase the stress area of ​​the hinge part and avoid local stress concentration. Secondly, the lugs, bosses, and fixing pins of the hinged parts are all made of high-strength alloy materials. The tensile strength of the fixing pin is not less than 600 MPa, and the yield strength of the lugs and bosses is not less than 300 MPa, ensuring that the materials themselves have sufficient load-bearing capacity.

[0029] Furthermore, the mounting frame 33 is made of aluminum alloy. In this embodiment, the mounting frame 33 is made of 6061-T6 high-strength aluminum alloy to ensure that the mounting frame 33 does not bend or deform when bearing the mounting ring 4 and the yarn feeder.

[0030] The top of the tail end of the mounting bracket 33 is provided with a first mounting hole 34. The mounting bracket 33 is detachably and fixedly mounted with a mounting ring 4 through the first mounting hole 34. In this embodiment, a connecting bracket is provided on the outside of the mounting ring 4. A connecting post that is compatible with the first mounting hole 34 is provided at the bottom of the connecting bracket. The mounting ring 4 is detachably and fixedly mounted in the first mounting hole 34 through the connecting post, thereby making the mounting ring 4 detachably and fixedly mounted on the mounting bracket 33. It should be noted that the connecting bracket on the outside of the mounting ring 4 is existing technology, and its structure will not be described in detail.

[0031] The bottom of the support frame 32, away from the connecting plate 31, has a locking hole 35. When the fixing pin is loose, the mounting bracket 33 can rotate around the hinge point to the side of the support frame 32 away from the connecting plate 31 and be fitted onto the outside of the support frame 32. At this time, the first mounting hole 34, which is farthest from the connecting plate 31, is coaxially aligned with the locking hole 35. The mounting bracket 33 can be folded and locked by inserting a lock to prevent the mounting bracket from being accidentally unfolded due to bumps and vibrations during transportation.

[0032] In one embodiment, reference is made to Figure 2 The left and right sides of the support frame 32 are symmetrically and detachably connected with reinforcing ribs 36. The end of the reinforcing rib 36 away from the support frame 32 is detachably connected to the left and right sides of the mounting frame 33 to form a triangular support structure. The triangular structure formed by the reinforcing ribs 36 can evenly distribute the longitudinal load borne by the mounting frame 33 and the transverse tension generated by the yarn conveying to the support frame 32 and the reinforcing ribs 36, avoiding the cantilever deformation of the mounting frame 33 which only relies on the hinge point for stress, ensuring that the mounting frame 33 and the support frame 32 always maintain the support angle, and ensuring the stability of the yarn conveying path. The reinforcing rib 36 is designed to be detachable. Before transportation, the connecting parts between the reinforcing rib 36 and the support frame 32 and the mounting frame 33, such as bolts and buckles, can be removed to release the triangular support constraint. This does not prevent the mounting frame 33 from rotating around the hinge point and being fitted onto the outside of the support frame 32, thus achieving the dual effects of load-bearing reinforcement and convenient transportation.

[0033] In one embodiment, reference is made to Figure 2 The mounting bracket 33 has several sets of locking holes 331 through the left and right sides of the front end. Through the multiple sets of locking holes 331, the embedding depth of the mounting post 333 can be changed in conjunction with the locking post 332 to meet the installation radius requirements of different specifications of mounting ring 4.

[0034] A locking post 332 is detachably embedded in the locking hole 331. When the mounting bracket 33 is unfolded, the bottom of the mounting bracket 33 is detachably fitted with a mounting post 333 for extending the installation radius through the locking hole 331 and the locking post 332. The mounting bracket 33 can adjust the embedding depth of the mounting post 333 through the locking hole 331 and the locking post 332 to adapt to different specifications of mounting rings 4.

[0035] In one embodiment, reference is made to Figure 3 The mounting column 333 includes a square steel 3321, which is used to support the weight of the mounting ring 4 during installation.

[0036] The top of the square steel 3321 has a second mounting hole 3322 for assembling the mounting ring 4. The second mounting hole 3322 is used to fix the connecting post that fits at the bottom of the mounting ring 4 to the top of the mounting post 333.

[0037] The square steel 3321 has several sets of adjustment holes 3323 that are adapted to the locking hole 331 through the left side. When the square steel 3321 is embedded in the bottom of the mounting bracket 33, one set of adjustment holes 3323 is aligned with the locking hole 331, and the square steel 3321 is fixed by the locking post 332 embedded in the two. Then, the mounting ring 4 is installed by the second mounting hole 3322.

[0038] In one embodiment, reference is made to Figures 4-5 The support frame 32 includes an outer frame 321 and an inner frame 323. A connecting plate 31 is fixedly installed on the outer top edge of the outer frame 321. The outer frame 321 has a hollow structure inside, which provides space for the sliding insertion of the inner frame 323 and is also used to install the connecting plate 31, so that the height of the connecting plate 31 can be adjusted synchronously.

[0039] The inner frame 323 is fixedly installed at the top of the mounting plate 1. The inner frame 323 is used to cooperate with the outer frame 321 to achieve height adjustment. When in use, the inner frame 323 can be pulled outwards from the outer frame 321 to increase the overall height.

[0040] The outer frame 321 has a first embedding hole 322 at its outer bottom. The top of the inner frame 323 is slidably embedded into the outer frame 321. The outer bottom of the inner frame 323 has a second embedding hole 324 that matches the first embedding hole 322. The first embedding hole 322 and the second embedding hole 324 are used to provide an installation interface for the pin 325, so as to fix the relative position of the outer frame 321 and the inner frame 323.

[0041] Pins 325 are embedded in the first embedding hole 322 and the second embedding hole 324. The outer frame 321 and the inner frame 323 are fixed by the pins 325, thereby adjusting the overall length of the support frame 32.

[0042] During adjustment, first pull out the pin 325 that is embedded in the first embedding hole 322 and the second embedding hole 324 to release the fixation between the outer frame 321 and the inner frame 323. If the height needs to be increased, pull the outer frame 321 upward or pull the inner frame 323 outward. By sliding the inner frame 323 in the hollow outer frame 321, the nesting depth of the two is changed, so that the connecting plate 31 rises synchronously with the outer frame. If the height needs to be decreased, push the inner frame 323 into the outer frame 321 to shorten the overall length after the two are nested. After adjusting to the target height, the pin 325 is re-embedded into the aligned first embedding hole 322 and second embedding hole 324. The pin 325 blocks the relative sliding of the outer frame 321 and the inner frame 323, thereby fixing their positions and completing the height adjustment of the support frame 32.

[0043] Working principle: Height adjustment: When lowering the height, first pull out the pin 325, push the inner frame 323 inward into the outer frame 321 to increase the nesting depth of the two. After the first embedding hole 322 of the outer frame 321 is aligned with the second embedding hole 324 of the inner frame 323, insert the pin 325 to fix it, and the connecting plate 31 will be lowered synchronously with the outer frame 321. When raising the height, pull out the pin 325, pull the inner frame 323 outward from the outer frame 321 to reduce the nesting depth, align the holes and then insert the pin 325 to fix it. The connecting plate 31 will rise synchronously with the outer frame 321.

[0044] Easy installation: The connecting plate 31 is fixed to the top of the outer side of the telescopic column 2, providing a stable installation reference for the support frame 32. The top of the support frame 32 is hinged to the mounting frame 33 by a fixing pin. Before installation, the fixing pin is in a loose state. Manually rotate the mounting frame 33 around the hinge point to the horizontal extension position. After it is in place, insert the fixing pin into the hinge hole of the two to lock it and complete the installation. When installing the mounting ring 4 without extending the radius, simply align the bottom connecting post of the outer connecting bracket of the mounting ring 4 with the first mounting hole 34 at the tail end of the mounting bracket 33, and insert it to achieve detachable fixing of the mounting ring 4.

[0045] When the installation ring 4 needs to be installed with an extended radius, first embed the square steel 3321 of the mounting post 333 into the bottom of the mounting bracket 33. Adjust the embedding depth according to the required radius so that a set of adjustment holes 3323 of the square steel 3321 are aligned with the locking holes 331 of the mounting bracket 33. Insert the locking post 332 to fix it. Then connect and fix the installation ring 4 to the second mounting hole 3322 at the top of the square steel 3321 with the bottom bolt to adapt to the installation radius requirements of the large-diameter installation ring 4.

[0046] When installing the reinforcing rib 36, first align its two ends with the connection points in the middle of the support frame 32 and the mounting frame 33, and then connect and fix it by tightening bolts or snap-fitting to form a triangular support structure. The triangular support will distribute the load and prevent the mounting frame 33 from deforming.

[0047] Storage and transportation: When storing the mounting ring 4, if the installation does not require an extension radius, the mounting ring 4 can be removed by simply pulling out the connecting post; If the extended radius installation is used, first remove the connecting bolts between the mounting ring 4 and the square steel 3321, then pull out the locking post 332, and pull the mounting post 333 out from the bottom of the mounting bracket 33; When storing the reinforcing rib 36, first loosen the bolts or unfasten the clips to disengage the reinforcing rib 36 from the connection point in the middle of the support frame 32 and the mounting frame 33, and then remove the reinforcing rib 36. When storing the mounting bracket 33, first loosen the fixing pin so that it comes out of the hinge hole between the support bracket 32 ​​and the mounting bracket 33, then rotate the mounting bracket 33 around the hinge point to the side away from the connecting plate 31 until it is fitted onto the outside of the support bracket 32. At this time, align the first mounting hole 34 of the mounting bracket 33 with the locking hole 35 of the support bracket 32 ​​and insert the lock to lock it. Finally, retract the telescopic column 2 to its shortest length, and simultaneously pull out the pin 325. Push the inner frame 323 of the support frame 32 completely into the outer frame 321, and then re-insert the pin 325 into the first insertion hole 322 and the second insertion hole 324 to fix it. This completes the overall storage, greatly reducing the size of the yarn frame and making it easier to transport.
