Abstract
Description
Technical Field
[0001] This utility model generally relates to the technical field of spinning equipment, and more specifically to a yarn break splicing device and a production equipment for fiber products. Background Technology
[0002] Continuous fibers, used as reinforcement in composite materials, significantly impact the performance of the finished product due to their conveying stability. Because of their fine filaments, continuous fibers inevitably experience abnormalities such as yarn compression and roller entanglement, making them prone to breakage. After a breakage, the yarn loses tension and becomes free, preventing the fiber bundle from unwinding. This leads to defects in the composite tape, such as dry, striped yarn and cracking. Therefore, timely detection and intervention are crucial to prevent these defects. Furthermore, the absence of fiber bundles and reduced fiber content after a breakage results in decreased mechanical properties of the finished product.
[0003] Similar to the yarn unwinding process in the traditional textile industry, there are also many methods for detecting yarn breaks during production using continuous fibers. However, current testing methods only have the ability to detect yarn breaks and cannot further address them, resulting in low operational efficiency. Utility Model Content

[0059] Figures 1 to 5 A yarn breakage splicing device 110 according to the present invention is shown, used in a production equipment for fiber products. The production equipment includes a traction device 100 for traction of continuous fibers 105. The yarn breakage splicing device 110 includes a yarn breakage sensing mechanism, a yarn preparation mechanism 130, a splicer 140, and a controller. The yarn breakage sensing mechanism is used to detect broken fibers 107 in the continuous fibers 105. The yarn preparation mechanism 130 is used to place and release prepared fibers 106. The splicer 140 is used to connect the prepared fibers 106 and the broken fibers 107. The controller is electrically connected to both the yarn breakage sensing mechanism and the splicer 140, and the controller is configured to control the splicer 140 to connect the prepared fibers 106 and the broken fibers 107 according to a trigger signal from the yarn breakage sensing mechanism.
[0060] The yarn preparation mechanism 130 is movably arranged relative to the splicer 140. The yarn preparation mechanism 130, located in the initial position, is arranged on one side of the splicer 140 along the first horizontal direction, so that after the yarn preparation fiber 106 of the yarn preparation mechanism 130 is connected to the broken yarn fiber 107, it can be transferred to the other side of the splicer 140.
[0061] According to the yarn breakage splicing device 110 of this utility model, when a yarn breakage occurs during the production of fiber products, the yarn breakage sensing mechanism detects the broken fiber 107 in the continuous fiber 105. The controller receives a trigger signal and controls the splicer 140 to connect the spare yarn fiber 106 and the broken yarn fiber 107, thereby ensuring the continued production of fiber products. Compared with manual yarn splicing, the splicing efficiency is high, thus greatly improving the operating efficiency of fiber products. In addition, after the spare yarn fiber 106 is connected to the broken yarn fiber 107, the spare yarn mechanism 130 can be transferred downstream of the splicer 140, so as not to affect the next yarn splicing operation.
[0062] Figure 2 The diagram illustrates the arrangement of the yarn-breaking splicing device 110 according to the present invention in a traction device 100. The present invention also discloses a fiber product manufacturing equipment, including the yarn-breaking splicing device 110 and the traction device 100 described above. The traction device 100 includes a first fiber guide roller 101 and a traction roller 104, which are spaced apart along a first horizontal direction D1 to allow continuous fibers 105 to be transferred from the first fiber guide roller 101 to the traction roller 104. The yarn-breaking splicing device 110 is disposed between the first fiber guide roller 101 and the traction roller 104.
[0063] According to the fiber product production equipment of this utility model, when a yarn breaks, it can automatically splice the yarn. Compared with the manual splicing method, the splicing efficiency is high, thereby greatly improving the operating efficiency of fiber products.
[0064] Optionally, the traction device 100 further includes a yarn separating reed 103 and a second fiber guide roller 102. The yarn separating reed 103 is used to separate the continuous fibers 105 along the second horizontal direction D2. The second fiber guide roller 102 is disposed between the yarn separating reed 103 and the traction roller 104 to guide the continuous fibers 105, so that the continuous fibers 105 pass smoothly through the yarn separating reed 103 without easily rubbing against it.
[0065] Depend on Figure 2 It can be seen that in the production process of fiber products, continuous fibers 105 are arranged along the second horizontal direction D2 and pass through the first fiber roller 101, the yarn breaking splicing device 110, the yarn separating reed 103, the second fiber roller 102 and the traction roller 104 in sequence along the first horizontal direction D1. As the traction roller 104 rotates continuously, the continuous fibers 105 are continuously conveyed.
[0066] The specific structure of the yarn breakage splicing device 110 will be further explained below with reference to the accompanying drawings.
[0067] Reference Figure 1 and Figure 2Optionally, the yarn breakage splicing device 110 further includes a guide frame 150, which includes a guide brace 152 extending from high to low along a second horizontal direction D2 perpendicular to the first horizontal direction D1 to the splicer 140. The guide brace 152 guides the broken yarn fiber 107 to the splicer 140, allowing the broken yarn fiber 107 to be connected with the spare yarn fiber 106 within the splicer 140. The guide brace 152 can be made of a smooth-surfaced material, such as stainless steel or glass. The guide brace 152 can also have a polytetrafluoroethylene (PTFE) material on its surface, resulting in a low coefficient of friction and facilitating the guidance of the broken yarn fiber 107 to the splicer 140.
[0068] Optionally, the guide frame 150 further includes a third fixing frame 151, which is spaced apart from the splicer 140 along the second horizontal direction D2 and extends along the height direction D3. The highest end of the guide brace 152 is connected to the upper end of the third fixing frame 151, and the lowest end of the guide brace 152 is connected to the splicer 140. When a broken yarn fiber 107 appears in the traction device 100, the broken yarn fiber 107 will fall into the guide brace 152 under its own weight due to the lack of tension at its end, and then slide down along the guide brace 152 to the splicer 140.
[0069] Optionally, the guide frame 150 includes two guide braces 152 and two third fixing frames 151. Along the second horizontal direction D2, the two guide braces 152 are respectively arranged on both sides of the splicer 140. Correspondingly, the two third fixing frames 151 are arranged on both sides of the splicer 140 along the second horizontal direction D2, so that when a yarn break occurs in the continuous fiber 105, the stroke of the broken yarn fiber 107 from the guide brace 152 to the splicer 140 is shorter, preventing the broken yarn fiber 107 from failing to connect with the spare yarn fiber 106 in time due to the continuous traction of the traction roller 104.
[0070] Combination Figure 3 As shown, the yarn breakage splicing device 110 also includes a guide mechanism 160, which includes a guide head 161 and a drive member 162. The guide head 161 is movably connected to the guide brace 152 along the extending direction of the guide brace 152. Figure 4 As shown, in detail, the guide head 161 is provided with a communication port 163 so that it can be fitted onto the guide brace 152, allowing the guide head 161 to be movably connected to the guide brace 152 along its extension direction. A drive member 162 is connected to the guide head 161 and is used to drive the guide head 161 to move along the extension direction of the guide brace 152. When the broken yarn fiber 107 falls into the guide brace 152, the guide head 161 moves along the guide brace 152, thereby guiding the broken yarn fiber 107 to the splicer 140.
[0071] Reference Figure 3 and Figure 4 The driving component 162 includes a motor 164, a driving wheel 165, a driven wheel 166, and a transmission component 167. The motor 164 is fixed relative to the guide frame 150. The driving wheel 165 is connected to the output shaft of the motor 164. Along the extension direction of the guide brace 152, the driven wheel 166 and the driving wheel 165 are respectively arranged at both ends of the guide brace 152, and the driven wheel 166 is rotatable relative to the guide frame 150. The two ends of the transmission component 167 are respectively wound around the driving wheel 165 and the driven wheel 166, and the transmission component 167 is connected to the guide head 161. When the motor 164 starts, the output shaft of the motor 164 drives the driving wheel 165 to rotate, thereby causing the transmission belt to move between the driving wheel 165 and the driven wheel 166, allowing the guide head 161 to move along the extension direction of the guide brace 152, thereby guiding the broken yarn fiber 107.
[0072] Optionally, the transmission component 167 can be a chain or a transmission belt, both of which can drive the guide head 161.
[0073] Optionally, the yarn breakage sensing mechanism includes a first sensing component 120, which is arranged along a first horizontal direction D1 on the side of the yarn preparation mechanism 130 away from the splicer 140. The first sensing component 120 is electrically connected to a controller, which is electrically connected to a drive component 162. The controller is configured to activate the drive component 162 according to a trigger signal sent by the first sensing component 120, so that the drive component 162 can be activated in a timely manner when a yarn breakage fiber 107 occurs, thereby guiding the yarn breakage fiber 107 to the splicer 140 in a timely manner. Specifically, the controller is electrically connected to a motor 164 of the drive component 162, which can be selected as a servo motor, thereby controlling and driving the guide head 161.
[0074] Optionally, the first sensing component 120 includes a transmitter 122 and a receiver 123, which are spaced apart along a second horizontal direction D2. The transmitter 122 senses broken fibers 107 that obstruct light between the transmitter 122 and receiver 123 and sends a trigger signal. The transmitter 122 is electrically connected to a controller. When a broken fiber 107 appears between the first fiber roller 101 and the reed 103, the broken fiber 107 and its end fall under its own weight, thus passing between the transmitter 122 and receiver 123, thereby generating a trigger signal within the transmitter 122. Specifically, the first sensing component 120 can be an infrared sensor, which can effectively sense the broken fiber 107 passing between the transmitter 122 and receiver 123.
[0075] Furthermore, the yarn breakage splicing device 110 also includes an alarm, and a controller is electrically connected to the alarm. The controller is configured to control the alarm to sound based on a trigger signal sent by the first sensing component 120 (i.e., transmitter 122). When a yarn breakage fiber 107 occurs, the transmitter 122 sends a trigger signal to the controller, which then sends a control signal to the motor 164, thereby driving the guide head 161 to move along the guide brace 152 and guiding the yarn breakage fiber 107 that has fallen on the guide brace 152 to the splicer 140.
[0076] Optionally, the first sensing component 120 further includes two first fixing frames 121, which extend along the height direction D3. The two first fixing frames 121 are respectively connected to the transmitter 122 and the receiver 123, and the transmitter 122 and the receiver 123 are respectively disposed at the top of the two first fixing frames 121, so as to timely sense the broken yarn fiber 107 passing between the transmitter 122 and the receiver 123 and improve the yarn splicing efficiency.
[0077] Optionally, refer to Figure 5 The yarn breakage sensing mechanism includes a second sensing component 170, which is disposed in the splicer 140 and used to sense the broken yarn fiber 107 entering the splicer 140 and send a trigger signal. The second sensing component 170 is electrically connected to a controller, which is configured to start the splicer 140 according to the trigger signal sent by the second sensing component 170. When the guide head 161 guides the broken yarn fiber 107 into the splicer 140, the second sensing component 170 sends a trigger signal to the controller, and then the controller controls the splicer 140 to start, realizing the connection between the spare yarn fiber 106 and the broken yarn fiber 107.
[0078] Optionally, the second sensing component 170 may be a light sensor that can effectively sense the broken yarn fiber 107 entering the splicer 140.
[0079] Optionally, the splicer 140 can be a pneumatic splicer 140, with air pipes 141 connected to both sides of the splicer 140, and the interfaces of the two air pipes 141 within the splicer 140 having a height difference, thereby achieving splicing of the broken yarn fiber 107 and the spare yarn fiber 106 through two high-speed airflows.
[0080] Reference Figure 1The yarn preparation mechanism 130 includes a second fixed frame 131 and a spindle 132. The spindle 132 is rotatably connected to the second fixed frame 131 and is provided with preparation yarn fibers 106. Before splicing the broken yarn fiber 107, the operator pre-places the end of the preparation yarn fiber 106 into the splicer 140, so that the broken yarn fiber 107 can be connected to the preparation yarn fiber 106 in time when it enters the splicer 140. In addition, as the traction roller 104 continues to rotate, the broken yarn fiber 107, along with the preparation yarn fiber 106, is conveyed to the reed 103. The spindle 132 continues to rotate, thereby continuously releasing the preparation yarn fiber 106, ensuring the stable production of fiber products in the production equipment. Furthermore, when the operator places the end of the spare yarn fiber 106 into the splicer 140 in advance, a section of the spare yarn fiber 106 can be left between the spindle 132 and the splicer 140 to prevent the splicer 140 from generating tension immediately after splicing the first point, causing the fiber to detach from the splicer 140 (because the broken yarn fiber 107 is simultaneously pulled by the traction roller 104). This allows for multi-point splicing of the broken yarn fiber 107 and the spare yarn fiber 106.
