Description

Technical Field

[0001] This invention relates to the field of air splicer technology, and in particular to a multi-joint yarn knotter. Background Technology

[0002] Due to the diversification of yarn types, especially the widespread use of special yarns (such as glass fiber, carbon fiber, and aramid) in actual production processes, increasingly higher requirements are being placed on the quality and strength of yarn splices. Traditional yarn splicing devices can only produce single splices, which poses a significant obstacle to subsequent processing steps. While manual knotting can meet the requirements, its low efficiency cannot satisfy current production needs. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the problems that the yarn splicing device in the prior art can only make a single joint and that the manual knotting method is inefficient.

[0004] To solve the above-mentioned technical problems, the present invention provides a multi-joint yarn knotter, comprising a block, wherein the block is provided with an air inlet for introducing compressed air, and the block is further provided with:

[0005] Multiple gas passages, including passage two, passage three, passage four, passage five, and passage six;

[0006] An intake piston assembly is connected to the intake port. The second channel can communicate with the intake port when the intake piston assembly moves, so as to communicate with the fifth channel through the third channel.

[0007] The switching piston valve rod assembly is able to move under the drive of compressed air in the fifth channel, and connect the second channel to the sixth channel.

[0008] The twisting components are arranged side by side in sequence, and each twisting component includes a twisting piston assembly, a twisting cavity, a channel seven, and a channel eight;

[0009] In the first set of twisting components, channel six is ​​connected to channel seven. The twisting piston assembly can move under the push of compressed air in channel seven, so that channel three is connected to the splicing cavity through channel eight. When the twisting piston assembly continues to move, channel three can be connected to channel nine.

[0010] Each of the twisting components is connected through the channel nine.

[0011] In one embodiment of the present invention, a scissor assembly is further provided at both ends of each of the twisting components. The scissor assembly includes a cavity cover piston assembly, a scissor body, a scissor connecting rod, a cavity cover bracket, and a cavity cover. It also includes a channel four communicating with the second channel. The fourth channel is connected to the lower end of the cavity cover piston assembly. The cavity cover piston assembly is connected to the scissor body through the scissor connecting rod and to the cavity cover through the cavity cover bracket. When the cavity cover piston assembly moves upward, it can close the cavity cover in the twisting cavity and cause the scissor body to perform a cutting action.

[0012] In one embodiment of the present invention, the scissor body includes mutually hinged serrated scissor blades.

[0013] In one embodiment of the present invention, yarn support plates are provided on both sides of each of the scissor bodies.

[0014] In one embodiment of the present invention, a reset channel is further included. The channel nine in the last set of twisting components is connected to the air intake piston assembly, allowing the compressed air to enter the reset channel. The reset channel is connected to the cavity cover piston assembly and the twisting piston assembly respectively and is used to reset them.

[0015] In one embodiment of the present invention, the reset channel includes channel one, channel eleven, channel twelve, channel thirteen, channel fourteen, and channel fifteen integrated within the block body. Channel one is connected to channel thirteen and channel fourteen, channel fourteen is connected to channel fifteen, channel thirteen is connected to channel twelve, channel fifteen is connected to channel eleven, channel twelve is connected to the reset piston on one side of the twisting piston assembly, and channel eleven is connected to the upper end of the cavity cover piston assembly.

[0016] In one embodiment of the present invention, the invention further includes channels sixteen, seventeen, eighteen and nineteen integrated within the block body. Channel nine in the last set of twisting components sequentially drives the intake piston assembly through channels sixteen, seventeen, eighteen and nineteen, allowing compressed air to enter channel one.

[0017] In one embodiment of the present invention, the air inlet and the twisting assembly are respectively disposed at opposite ends of the block.

[0018] The technical solution of the present invention has the following advantages compared with the prior art:

[0019] The multi-joint yarn knotter of this invention, through innovative air passage design and multi-component collaborative work, enables the simultaneous knotting of multiple yarn joints, which significantly improves the knotting success rate and reduces time and labor costs in the production process.

[0020] This invention uses compressed air as the driving force, which has the advantages of low cost and high efficiency. This driving mechanism is not only economical but also provides sufficient power to complete complex knotting operations.

[0021] The scissor assembly of this invention features an innovative design, including serrated scissor blades and a yarn support plate. This not only effectively prevents yarn slippage but also extends the lifespan of the scissors, making them more durable.

Therefore, it should not be construed as a limitation of this invention.

[0042] In this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc., are understood to exclude the stated number; "above," "below," "within," etc., are understood to include the stated number. In the description of this invention, the terms "first" and "second" are used only to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0043] In this invention, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention based on the specific content of the technical solution.

[0044] Reference Figure 1 , Figure 4 As shown, a multi-joint yarn knotter of the present invention includes a block 100, wherein the block 100 is provided with an air inlet 110 for introducing compressed air, and the block 100 is further provided with:

[0045] Multiple gas passages, including passage 2, passage 3, passage 4, passage 5, and passage 6;

[0046] The intake piston assembly 120 is connected to the intake port 110. The second channel 2 can communicate with the intake port 110 when the intake piston assembly 120 moves, so as to communicate with the fifth channel 5 through the third channel 3.

[0047] The switching piston valve rod assembly 130 is capable of moving under the drive of compressed air within the fifth channel 5, and connects the second channel 2 to the sixth channel 6;

[0048] The twisting components 140 are arranged side by side in sequence. Each twisting component 140 includes a twisting piston assembly 141, a twisting cavity 142, a channel 7, and a channel 8.

[0049] In the first twisting assembly 140, the sixth channel 6 is connected to the seventh channel 7. The twisting piston assembly 141 can move under the push of compressed air in the seventh channel 7, so that the third channel 3 is connected to the splicing cavity 142 through the eighth channel 8. When the twisting piston assembly 141 continues to move, the third channel 3 can be connected to the ninth channel 9.

[0050] Each of the twisting components 140 is connected through the channel 9.

[0051] In some embodiments, refer to Figure 2 , Figure 5As shown, it also includes scissor assemblies 150 disposed at both ends of each of the twisting assemblies 140. The scissor assembly 150 includes a cavity cover piston assembly 151, a scissor body 152, a scissor connecting rod 153, a cavity cover bracket 154, and a cavity cover 155. It also includes a channel 4 communicating with the second channel 2. The channel 4 is connected to the lower end of the cavity cover piston assembly 151. The cavity cover piston assembly 151 is connected to the scissor body 152 through the scissor connecting rod 153 and to the cavity cover 155 through the cavity cover bracket 154. When the cavity cover piston assembly 151 moves upward, it can close the cavity cover 155 in the twisting cavity 142 and cause the scissor body 152 to perform a cutting action.

[0052] In some embodiments, the scissor body 152 includes mutually hinged serrated scissor blades 156. The scissor assembly 150 plays a role in cutting the yarn tail during the yarn knotting process. In conventional cutting structures, the yarn will slide towards the top of the scissors during the cutting process, which increases the cutting pressure at the top of the scissors and shortens the service life of the scissors. However, the result of the present invention can play a role in "fixing the yarn to prevent escape and reducing pressure by separating strands" in the scissors, which greatly improves the service life of the scissors.

[0053] In some embodiments, refer to Figure 1 As shown, each of the scissor bodies 152 has a yarn support plate 157 on both sides. The yarn support plate 157 is provided with a threading channel, a yarn support groove, and other structures. It can be understood that when cutting yarn, the ends of the two joined yarns are placed on the yarn support plate 157 respectively.

[0054] In some embodiments, refer to Figures 6 to 11 As shown, it also includes a reset channel. The channel 9 in the last set of twisting components 140 is connected to the air intake piston assembly 120, so that the compressed air enters the reset channel. The reset channel is connected to the cavity cover piston assembly 151 and the twisting piston assembly 141 respectively and is used to reset them.

[0055] In some embodiments, refer to Figure 5 As shown, the reset channel includes channel 1, channel 11, channel 12, channel 13, channel 14, and channel 15 integrated within the block 100. Channel 1 is connected to channel 13 and channel 14 respectively. Channel 14 is connected to channel 15. Channel 13 is connected to channel 12. Channel 15 is connected to channel 11. Channel 12 is connected to reset piston 158 on one side of twisting piston assembly 141. Channel 11 is connected to upper end of cavity cover piston assembly 151.

[0056] In some embodiments, refer to Figure 9, Figure 11 As shown, it also includes channels 16, 17, 18, and 19 integrated within the block 100. In the last set of twisting components 140, channel 9 pushes the intake piston assembly 120 to move through channels 16, 17, 18, and 19 in sequence, so that compressed air enters the channel 1.

[0057] In some embodiments, the air inlet 110 and the twisting assembly 140 are respectively disposed at opposite ends of the block 100.

[0058] Reference Figure 12 , Figure 13 As shown, each of the above-mentioned piston assemblies includes components such as a piston head and a piston rod, and the switching piston valve rod assembly 130 includes a piston head and a valve rod. The position and number of piston heads can be set according to the specific function to be implemented.

[0059] During operation, compressed air is introduced through the air inlet 110, causing the air inlet piston assembly 120 to move to the left, allowing the compressed air to enter channel 2. The compressed air in channel 2 enters channel 3 and channel 4, while the compressed air in channel 1 is closed. At this time, the compressed air in channel 4 pushes the cavity cover piston assembly 151 to move upward, causing the scissor connecting rod 153 to drive the scissor body 152 to cut the yarn tails of the two joined yarns. At the same time, the cover piston assembly also moves the cavity cover bracket 154 and the cavity cover 155, so that the cavity cover 155 covers the splicing cavity 142.

[0060] Compressed air in channel 3 enters channel 5, thereby pushing the piston head in the switching piston valve rod assembly 130 downward. Through the valve rod, compressed air in channel 2 enters channel 6 and then turns into channel 7, thereby pushing the twisting piston assembly 141 to move to the left. As the twisting piston assembly 141 moves to the left, the compressed air in channel 3 enters channel 8 and flows out through the hole in the twisting chamber 142, acting on the yarn. As the twisting piston assembly 141 continues to move to the left, the compressed air entering channel 8 from channel 3 will be closed, and a knot is completed.

[0061] The twisting piston assembly 141 continues to move to the left, causing the compressed air in channel 3 to enter channel 9. The compressed air in channel 9 then enters channel 7 in the next twisting assembly 140, completing the above knotting action twice in sequence.

[0062] Finally, the compressed air returning to channel 9 passes through channels 16, 17, 18, and 19 in sequence, pushing the intake piston assembly 120 to the right. The compressed air enters channel 1, and from channel 1, it simultaneously enters channels 13 and 14, then 15, and finally 11 and 12. This causes the cavity cover piston assembly 151 to drive the cavity cover support 154, cavity cover 155, scissor body 152, and scissor connecting rod 153 to reset. At the same time, the reset piston 158 pushes the twisting piston assembly 141 to reset, and the entire knotting action is completed.

[0063] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
