Description

Technical Field

[0001] This utility model belongs to the field of warp knitting machines, and specifically relates to the warp beam frame of a high-low pile warp knitting machine. Background Technology

[0002] In existing technology, multiple disc heads are typically supported by a single axle on the warp beam support. This places significant demands on the company's space. Furthermore, for some special products, such as those requiring high-quality dual-carriage systems, the individual axles can interfere with each other when changing disc heads, which can have a significant impact on product quality.

[0003] When a segmented warp beam design is adopted, there is a need to install and adjust the intermediate support part of the segmented warp beam on the warp beam frame, but the existing warp beam frame is inconvenient for workers to operate. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention improves the structure of the warp beam frame. An added intermediate support component supports the segmented warp beams. Furthermore, the uprights are perpendicular to the ground, providing better load-bearing capacity. The warp beam frame also features side steps, providing a platform for workers to step onto the upper warp beam, facilitating yarn separation and threading operations, ensuring worker safety, and improving work efficiency. Additionally, the support tube assembly is reinforced to meet the load-bearing requirements of the segmented warp beams.

[0005] The technical solution of this utility model is as follows:

[0006] A warp beam frame for a high-low pile warp knitting machine includes a front column assembly and a rear column assembly arranged at both ends along the length of the warp knitting machine, and a support tube assembly connecting the front column assembly and the rear column assembly. The support tube assembly has an intermediate support assembly located in the middle, which supports one end of a segmented warp beam. The intermediate support assembly includes a lower fixing plate fixedly connected to the surface of the support tube assembly, and a support plate connected to the lower fixing plate. The top of the support plate is machined with symmetrically arranged coaxial bearing mounting grooves.

[0007] Furthermore, the support plate is provided with a cover plate on its end face, which is used to limit the bearing mounting groove axially, and the upper end of the support plate is provided with a pressure plate to cover the bearing mounting groove.

[0008] Furthermore, the two sides of the support plate are also fixed with axle brackets by screws.

[0009] Furthermore, the front column assembly and the rear column assembly have the same structure. The front column assembly includes a first tall column arranged symmetrically and a first short column arranged symmetrically outside the first tall column. The upper ends of the two first tall columns are connected to an upper crossbeam. A connecting support pipe is provided between the first tall column and the first short column. The first tall column and the first short column are set perpendicular to the ground.

[0010] Furthermore, the support tube assembly includes a first support tube, the two ends of which are connected to the upper middle part of the first short column of the front column assembly and the rear column assembly; a second support tube, the two ends of which are connected to the upper part of the first tall column of the front column assembly and the rear column assembly; and a third support tube, the two ends of which are connected to the opposite surfaces of the upper crossbeam of the front column assembly and the rear column assembly.

[0011] Furthermore, it also includes a side pedal assembly, which includes an end pedal bracket connected to the inner wall of the first high column of the front column assembly and the rear column assembly, and a pedal bracket connected to the middle of the lower surface of the second support tube. It also includes two side pedals, the two ends of which are slidably connected to the end pedal bracket and the pedal bracket, respectively.

[0012] Furthermore, the length of the pedal bracket and the end pedal bracket is 2-3 times the width of the side pedal.

[0013] Furthermore, it also includes a middle pedal, with raised plates at both ends of the lower surface of the middle pedal. The raised plates are connected to the middle of the upper surface of the upper crossbeam, and the third support tube is located on both sides of the middle pedal.

[0014] Furthermore, the distance between the middle pedal and the upper crossbeam is greater than 10cm.

[0015] Furthermore, the first, second, and third support tubes are made of square tubing measuring 140*180mm with a wall thickness of 6-10mm.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model improves the structure of the warp beam frame by adding an intermediate support component in the middle of the support tube assembly of the warp beam frame. On the one hand, it realizes the support of the segmented warp beam, which meets the needs of customers. On the other hand, the coaxiality of the two warp beams is ensured by supporting the ends of the two warp beams with the same support plate.

[0018] 2. Furthermore, the columns of the warp beam frame of this utility model are all set perpendicular to the ground, and the intermediate support components all form a vertical support for the warp beam, which has a better load-bearing capacity and overcomes the problem of poor stability and reliability of the inclined plate support in the prior art. Furthermore, the selection of the support tube component is optimized to improve the load-bearing capacity of the support tube component and reduce the bending of the support tube component after installation, thus better ensuring the coaxiality of the warp beam.

[0019] 3. This utility model further adds a side step on the warp beam frame, providing a platform for workers to walk on, which facilitates the assembly and adjustment of the connection between the segmented warp beam and the intermediate support assembly, and also facilitates the workers to perform yarn splitting and threading operations, thereby improving production efficiency.

The terms "vertical," "horizontal," "left," "right," "upper," "lower," and similar expressions used are for illustrative purposes only and do not represent the only possible implementation.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] In this invention, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0035] See Figures 1 to 5 As shown, the warp beam frame of the high-low pile warp knitting machine includes a front column assembly 1 and a rear column assembly 2 arranged at both ends of the warp knitting machine along its length, and a support tube assembly 3 connecting the front column assembly 1 and the rear column assembly 2. An intermediate support assembly 4 is provided in the middle of the support tube assembly 3. The intermediate support assembly 4 is used to support one end of the segmented warp beam. The intermediate support assembly 4 includes a lower fixing plate 40 fixedly connected to the surface of the support tube assembly 3, and a support plate 41 connected to the lower fixing plate. The lower support plate is vertically arranged on the lower fixing plate. The top of the support plate 41 is machined with symmetrically arranged coaxial bearing mounting grooves 410 for installing bearings on the warp beam. The lower fixing plate is fixed to the surface of the support tube assembly by welding, specifically located in the middle of the support tube assembly. The lower surface of the lower fixing plate is also provided with a reinforcing rib plate connected to the side wall of the support tube assembly to improve the load-bearing capacity of the support assembly.

[0036] This invention improves the warp beam frame. Due to customer site limitations and special production requirements, this invention designs a warp beam frame suitable for segmented warp beams. The intermediate support component supports one end of the segmented warp beam simultaneously, meeting customer usage needs. At the same time, the same support plate supports the ends of two warp beams, ensuring the coaxiality of the segmented warp beams, guaranteeing the reliability of yarn feeding, and contributing to the quality of warp knitting machine products.

[0037] See Figure 3 and Figure 4 As shown, a cover plate 411 is also provided on the end face of the support plate 41. The cover plate 411 is used to limit the bearing mounting groove axially. The upper end of the support plate 41 is also provided with a pressure plate 412 to cover the bearing mounting groove. The cover plate and pressure plate are used to achieve axial and circumferential positioning of the bearing of the warp shaft, ensuring the reliability and stability of the connection between the warp shaft and the support plate.

[0038] See Figure 4 As shown, the two sides of the support plate 41 are also fixed with warp shaft brackets 413 by screws. After the equipment has been used for a long time, the bearings on the warp shaft may fail. Therefore, the warp shaft brackets are added. When the gears on the warp shaft fail, the warp shaft brackets can support the warp shaft and prevent the end of the warp shaft from falling off the support plate, thus ensuring the safety of the equipment.

[0039] See Figure 1 , Figure 2 as well as Figure 5 As shown, the front column assembly 1 and the rear column assembly 2 of this utility model have the same structure. The front column assembly 1 includes a first tall column 10 arranged symmetrically and a first short column 11 arranged symmetrically outside the first tall column 10. The upper ends of the two first tall columns 10 are connected to an upper crossbeam 12. A connecting support tube 13 is provided between the first tall column 10 and the first short column 11. The first tall column and the first short column are set perpendicular to the ground. Each column of the front column assembly and the rear column assembly of this utility model is vertically connected to the ground, providing vertical support for the warp beam placed on the warp beam frame, resulting in stronger load-bearing capacity and better stability.

[0040] See Figure 2 and Figure 5As shown, the support tube assembly 3 includes a first support tube 30, with both ends of the first support tube 30 connected to the upper middle part of the first short column 11 of the front column assembly and the rear column assembly; a second support tube 31, with both ends of the second support tube connected to the upper part of the first tall column 10 of the front column assembly and the rear column assembly; and a third support tube 32, with both ends of the third support tube connected to the opposite surfaces of the upper crossbeam 12 of the front column assembly and the rear column assembly. The first, second, and third support tubes are square tubes with a cross-sectional dimension of 140*180mm and a thickness of 6-10mm. The tubes are produced by drawing. An installation end plate 300 is fixed to both ends of each of the first, second, and third support tubes. Both ends of the installation end plate protrude from the upper and lower surfaces of the support tube assembly, and a connecting through hole is provided on the installation end plate. Fasteners pass through the connecting through holes to achieve support. During the production process, the lower end face of the mounting end plate is used as a machining reference for fixing the tube assembly. The upper surface of the lower fixing plate is then machined using this reference, ensuring the horizontality between the two ends of the tube assembly and the upper surface of the lower fixing plate. Simultaneously, during the assembly of the tube assembly, a set of parallel positioning pins 301 are installed on the first short column and the first tall column. The lower end face of the mounting end plate 300 is tightly attached to the positioning pins 301, serving as the installation reference for the tube assembly. This also ensures the horizontality of the lower fixing plate of the installed tube assembly, which in turn helps ensure the coaxiality of the segmented warp beam. To further enhance the rigidity and load-bearing capacity of the warp beam frame, a fourth tube is installed at the lower part of the first tall column. This fourth tube forms a rigid connection between the lower part of the first tall column of the front column assembly and the rear column assembly, improving the structural stability of the warp beam frame.

[0041] See Figure 1 and Figure 5 As shown, it also includes a side pedal assembly 5, which includes an end pedal bracket 50 connected to the inner wall of the first high column 10 of the front column assembly 1 and the rear column assembly 2, and a pedal bracket 51 connected to the middle of the lower surface of the second support tube 31. It also includes two side pedals 52, the two ends of which are slidably connected to the end pedal bracket and the pedal bracket, respectively. The side pedal assembly is located above the side of the entire warp beam frame. Since the warp beam frame of this utility model is used to support the segmented warp beam, it is necessary for workers to install it on the side of the warp beam frame. The side pedal assembly provides an accessible area for workers to work, making it convenient for workers to carry out installation work. It also facilitates the yarn separation operation of the sand table on the warp beam.

[0042] The lengths of the pedal bracket 51 and the end pedal bracket 50 are 2-3 times the width of the side pedal 52. By limiting the length, it can be seen that the side pedal can move along the length of the pedal bracket between the pedal bracket and the end pedal bracket. When the side pedal is needed, it can be moved to one end of the pedal bracket. When it is not needed, it can be moved to the other end of the pedal bracket, reducing the encroachment of the side pedal on the side space of the warp beam frame. This also facilitates the replacement and maintenance of the warp beam located below the side pedal.

[0043] It also includes a middle pedal 6, with raised plates 60 at both ends of the lower surface of the middle pedal 6. The raised plates 60 are connected to the middle of the upper surface of the upper crossbeam 12. The third support tube 32 is located on both sides of the middle pedal. The distance between the middle pedal 6 and the upper crossbeam 12 is greater than 10cm. This utility model further improves the middle pedal by raising the distance between the middle pedal and the upper crossbeam through raised plates, leaving a safe and operable position, providing more space for workers to separate and thread yarn, facilitating operation and improving work efficiency.

[0044] In summary, this utility model has the following beneficial effects:

[0045] 1. This utility model improves the structure of the warp beam frame by adding an intermediate support component in the middle of the support tube assembly of the warp beam frame. On the one hand, it realizes the support of the segmented warp beams and meets the needs of customers. On the other hand, it supports the ends of the two warp beams through the same support plate, and improves the levelness of the support tube assembly by improving the processing and installation of the support tube assembly, thereby better ensuring the coaxiality of the segmented warp beams.

[0046] 2. Furthermore, the uprights of the warp beam frame of this utility model are all set perpendicular to the ground, and the intermediate support components all form a vertical support for the warp beam, which has a good load-bearing capacity and overcomes the problem of poor stability and reliability of the inclined plate support in the prior art. Furthermore, the selection of the support tube component is optimized to improve the load-bearing capacity of the support tube component and reduce the bending of the support tube component after installation, thus better ensuring the coaxiality of the warp beam.

[0047] 3. This utility model further adds a side step on the warp beam frame, providing a platform for workers to walk on, which facilitates the assembly and adjustment of the connection between the segmented warp beam and the intermediate support assembly, and also facilitates the workers to perform yarn splitting and threading operations, thereby improving production efficiency.

[0048] Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
