Description

Technical Field

[0001] This invention relates to the field of waste yarn collection devices, and particularly to waste yarn collection devices for water jet looms. Background Art

[0002] Water jet looms generally refer to shuttleless looms that use high-pressure water jets to insert weft threads. They are characterized by high speed, high efficiency, and low noise, and are widely used in the production of hydrophobic fiber fabrics. Currently, to clean up the waste selvage generated during the operation of water jet looms, they are usually equipped with waste selvage collection devices to prevent the fabric from suffering from edge breakage, tearing, or other serious quality issues caused by the entanglement of waste selvage threads.

[0003] Existing waste filament collection devices typically include a collection bucket, a pressure sensor, and a shearing mechanism. The collection bucket collects waste filaments, and the pressure sensor determines how much waste filaments have been collected by sensing the collection bucket. When the detected weight reaches the expected value, the shearing mechanism is triggered to cut the waste filaments, so that the collection bucket can be replaced and the waste filaments can be prevented from overflowing from the collection bucket.

[0004] However, during the collection of waste wires, the waste wires may be wetted by water mist or splashing water droplets, causing some moisture to be carried into the collection bucket along with the waste wires. Affected by this moisture, the pressure sensor is easily triggered when the collection bucket has not collected enough (the expected amount) of waste wires. The actual amount of waste wires in the collection bucket is lower than the expected amount, which not only reduces the collection efficiency but also easily leads to frequent equipment shutdowns. Summary of the Invention

[0005] The main objective of this invention is to provide a waste yarn collection device for a water jet loom, which aims to solve the problem in related technologies where moisture adhering to the waste yarn interferes with pressure sensor detection, thus reducing the collection efficiency of the waste yarn.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A waste selvage collection device for a water jet loom includes a collection mechanism and a guide mechanism for guiding the waste selvage into the collection mechanism. The collection mechanism includes a collection bucket, a cutting structure, a pressure sensor, and a collection base. The guide mechanism includes several extrusion gears and a guide pipe. The guide pipe is provided with a drying structure and a guiding structure. The side of the guide pipe close to the horizontal plane is provided with several first drainage holes.

[0007] Furthermore, the guiding structure includes an inlet tensioning and adjusting roller, an outlet tensioning and adjusting roller, and several sets of extrusion rollers. The inlet tensioning and adjusting roller, the outlet tensioning and adjusting roller, and the several sets of extrusion rollers are all rotatably connected to the guiding pipe. Each set of extrusion rollers is arranged sequentially along the distribution line of the guiding pipe, and the outlet tensioning and adjusting roller is located between two adjacent sets of extrusion rollers.

[0008] Furthermore, the guide pipe includes an upward bend and a downward bend, wherein the distance between the upward bend and the extrusion tooth shaft is less than the distance between the downward bend and the extrusion tooth shaft.

[0009] Furthermore, the drying structure includes several heating components, each of which is located between adjacent sets of extrusion rollers.

[0010] Furthermore, the cutting structure is fixedly installed on the guide pipe and located at one end of the guide pipe close to the collection bucket.

[0011] Furthermore, the cutting structure includes a cutting blade, a cutting seat, and a moving component for driving the cutting blade to move. The cutting seat is fixedly connected to the guide pipe, and the cutting blade is slidably connected to the cutting seat.

[0012] Furthermore, the collection base is provided with an installation port for cooperating with the collection bucket, the bottom of the collection bucket is provided with several second drainage holes, and the installation port is provided with a drain outlet.

[0013] Furthermore, the mounting port is provided with a mounting frame, which includes a central plate base and several support rods. The pressure sensor is located on the central plate base, and each of the support rods is evenly distributed around the central plate base in a circle. Several drain ports are provided, and each drain port is located between adjacent support rods, and each drain port has several second leakage holes above it.

[0014] Furthermore, the collection base includes a support body and a rotating disk. The rotating disk has several mounting ports. A rotating assembly for controlling the rotation of the rotating disk is provided between the support body and the rotating disk. The rotating assembly includes a rotating gear, a drive gear, and a drive motor. The drive gear is linked to the output shaft of the drive motor and meshes with the rotating gear. The rotating gear is integrally formed with the rotating disk. The axial length of the rotating disk is greater than the axial length of the rotating gear. The support body has a rotating hole with a diameter smaller than the diameter of the rotating gear.

[0015] Furthermore, the collection base is provided with a water storage tank, and the water storage tank is provided with a water storage container. The water storage container is slidably connected to the collection base, and the water storage container is connected to the drain outlet. The working principle and beneficial effects of this invention are as follows: This invention mainly includes a collection mechanism and a guiding mechanism. The guiding mechanism is responsible for introducing the waste selvage generated by the operation of the water jet loom into the collection mechanism. The guiding mechanism mainly includes a guiding pipe and several extrusion toothed shafts. Each extrusion toothed shaft is rotatably connected to the water jet loom. The collection path of the waste selvage is located between adjacent extrusion toothed shafts, so that the adjacent extrusion toothed shafts can form a clamping mechanism for the waste selvage, ensuring that the waste selvage is fed into the guiding pipe evenly and stably.

[0016] The guide pipe is equipped with a drying structure and a guiding structure. The guiding structure ensures that the waste filaments can move along the guide pipe and eventually enter the collection mechanism. The drying structure dries the waste filaments entering the guide pipe. In other words, the technical solution of this invention removes the moisture attached to the waste filaments by drying, thereby effectively reducing the possibility of moisture entering the collection mechanism. This fundamentally solves the problem of moisture attached to the waste filaments interfering with the detection accuracy of the pressure sensor in the collection mechanism, effectively ensuring that the waste filaments collected by the collection mechanism are close to the expected value, and thus ensuring the collection efficiency of waste filaments.

[0017] Meanwhile, the end of the guide pipe that is close to the horizontal plane (ground) is also provided with several first drainage holes, so that when the water attached to the waste wire passes through the guide pipe, some of the water droplets fall into the guide pipe and can be directly discharged from the guide pipe.

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] like Figures 1-2 As shown, this embodiment proposes a waste selvage collection device for a water jet loom, mainly including a collection mechanism 1 and a guiding mechanism 2 for guiding the waste selvage into the collection mechanism 1. The collection mechanism 1 includes a collection bucket 11, a cutting structure 12, a pressure sensor 13, and a collection base 14. The guiding mechanism 2 includes a guiding pipe 22 and several squeezing toothed shafts 21. Each squeezing toothed shaft 21 is rotatably connected to the external loom base, and a path for the waste selvage generated by the operation of the external water jet loom is formed between adjacent squeezing toothed shafts 21. When the waste selvage passes between adjacent squeezing toothed shafts 21, the mutual biting or pressing of two (adjacent) squeezing toothed shafts 21 forms a clamping mechanism for the waste selvage, ensuring that the waste selvage is fed evenly and stably into the guiding pipe 22.

[0024] If necessary, a support plate can be provided on the guide pipe 22, and the end of each extrusion tooth shaft 21 away from the loom base is rotatably connected to the support plate, so that both ends of each extrusion tooth shaft 21 have support points, effectively ensuring the stable rotation of the extrusion tooth shaft.

[0025] The guide pipe 22 is located between the collection bucket 11 (collection mechanism 1) and the external water-jet loom. The guide pipe 22 is equipped with a drying structure 23 and a guide structure 24. The presence of the guide structure 24 ensures that the waste selvage can move along the guide pipe 22 and finally enter the collection bucket 11.

[0026] like Figures 3-4 As shown, the guide pipe 22 includes an upward bend 221, a downward bend 222, an inlet, and an outlet. The presence of each bend makes the guide pipe 22 itself not a straight structure, effectively optimizing the conveying path of the waste yarn in the guide pipe 22. Because of the influence of the high-pressure water flow of the water jet loom, the guide pipe 22 will not only receive waste yarn, but also easily receive splashed water. In this case, the bend design of the guide pipe 22 can effectively prevent water from flowing into the collection bucket 11 along the guide pipe 22.

[0027] The distance between the upward bending part 221 and the extrusion tooth shaft 21 is smaller than the distance between the downward bending part 222 and the extrusion tooth shaft 21. That is, the guide pipe 22 is in the form of first bending upward and then bending downward, which can not only prevent water flow, but also facilitate the guide of waste wire to the collection bucket 11.

[0028] The guiding structure 24 in this embodiment mainly includes an inlet tensioning roller 241, an outlet tensioning roller 242, and several sets of squeezing rollers 243. The inlet tensioning roller 241, the outlet tensioning roller 242, and the several sets of squeezing rollers 243 are all rotatably connected to the guiding pipe 22. Correspondingly, the guiding pipe 22 includes an inlet and an outlet. The inlet tensioning roller 241 is located at the inlet, and the outlet tensioning roller 242 is located at the outlet. That is, the waste edge wire entering the guiding pipe 22 changes its direction of movement through the mutual cooperation of the inlet tensioning roller 241 and the outlet tensioning roller 242, and smoothly passes through the upward bending part 221 and the downward bending part 222 (guiding pipe 22) into the collection bucket 11. Each set of extrusion rollers 243 is arranged sequentially along the distribution line of the guide pipe 22, ensuring that when the waste edge wire passes through the guide pipe 22, it will also pass through several sets of extrusion rollers 243 (between adjacent extrusion rollers 243), so that the waste edge wire can be squeezed by the extrusion rollers 243 and squeeze out the water inside. Similarly, when the waste edge wire comes into contact with each tensioning roller, it will also receive pressure from each tensioning roller, squeezing out the water inside, thus achieving rapid dehydration.

[0029] Meanwhile, the outlet tensioning roller 242 is located between two adjacent sets of extrusion rollers 243. That is, after the waste edge wire changes its direction of movement by the outlet tensioning roller 242, it will pass through a set of extrusion rollers 243 before entering the collection bucket 11 from the outlet. With the extrusion and clamping effect of the set of extrusion rollers 243, the waste edge wire located in the guide pipe 22 is effectively prevented from rebounding rapidly and detaching from the outlet tensioning roller 242 due to the pretension of the waste edge wire after it is cut by the cutting structure 12. This effectively ensures the operational stability of this embodiment.

[0030] If necessary, the guide pipe 22 can be equipped with several disassembly plates and several disassembly ports. Each disassembly port is connected to the inside and outside of the guide pipe 22. Each disassembly plate is located in the corresponding disassembly port. Each disassembly plate and the guide pipe 22 are provided with several first threaded parts for fixing the disassembly plate to the guide pipe 22. That is, by removing the disassembly plate, the staff can adjust the routing of the waste wire inside the guide pipe 22, effectively ensuring that the waste wire can be sent to the collection bucket 11 through the guide structure 24.

[0031] Meanwhile, the end of the guide pipe 22 that is close to the horizontal plane (ground) is also provided with a number of first drainage holes 223, so that when the water attached to the waste wire passes through the guide pipe 22, after the water inside the waste wire is squeezed out of the waste wire by each set of extrusion rollers 243, the water droplets fall into the guide pipe 22 and can be discharged directly from the guide pipe 22 (along each first drainage hole 223).

[0032] The presence of the drying structure 23 allows for the drying of waste filaments entering the guide pipe 22. In this embodiment, drying and squeezing the waste filaments quickly removes moisture, effectively reducing the possibility of moisture entering the collection bucket 11. This fundamentally solves the problem of moisture adhering to the waste filaments interfering with the detection accuracy of the pressure sensor 13 (the weight of the moisture causes the pressure sensor 13 to be accidentally triggered when the collection bucket 11 has not collected enough waste filaments). This effectively ensures that the waste filaments collected by the collection mechanism 1 are close to the expected value, thereby guaranteeing the collection efficiency of the waste filaments.

[0033] The drying structure 23 includes several heating components 231. In this embodiment, the heating components 231 are preferably hot air blowers because the waste edge filaments are mostly loose filament bundles that easily form air channels. In this way, the hot air generated by the hot air blower can easily penetrate the interior of the waste edge filaments, effectively improving the dehydration efficiency and dehydration uniformity.

[0034] Furthermore, the step of removing moisture from waste wire by drying can also be regarded as a pretreatment for waste wire recycling (such as hot melt recycling), achieving two goals at once.

[0035] Each heating component 231 is located between each adjacent group of extrusion rollers 243. That is, the waste edge wire is first extruded and then dried. Because the mechanical extrusion energy consumption of each group of extrusion rollers 243 on the waste edge wire is much less than that of thermal evaporation, it can effectively remove easily removable moisture and effectively reduce the subsequent drying load.

[0036] like Figure 1 , Figure 4 , Figure 8 As shown, the collection base 14 in this embodiment is provided with an installation port 141 for cooperating with the collection bucket 11. The bottom of the collection bucket 11 is provided with several second drainage holes 111. The installation port 141 is provided with a drain outlet 142. In this way, even if some water or running water accidentally enters the collection bucket 11, it will eventually be discharged from the collection bucket 11 through each second drainage hole 111 under the action of gravity, further reducing the possibility of water residue inside the collection bucket 11 and further improving the detection accuracy of the pressure sensor 13.

[0037] Correspondingly, the mounting port 141 is provided with a mounting frame 143, which includes a central plate base 1431 and several support rods 1432. The pressure sensor 13 is located on the central plate base 1431 to ensure that the pressure sensor 13 is still in the center of the collection bucket 11 to ensure its detection accuracy. Each support rod 1432 is evenly distributed around the central plate base 1431. Several drain ports 142 are provided, and each drain port 142 is located between adjacent support rods 1432. Each drain port 142 has several second drainage holes 111 above it. That is, through the frame structure of the mounting frame 143, the collection bucket 11 is supported without blocking or obstructing the communication path between each second drainage hole 111 and each drain port 142.

[0038] At the same time, such as Figure 5 , Figure 7 As shown, the bottom of the inner cavity of the collection bucket 11 in this embodiment is provided with a partition frame. The partition frame includes a mating seat and several partition rods. Each partition rod is evenly distributed around the mating seat, so that the bottom of the collection bucket 11 is divided into chambers that correspond to and match each drain outlet 142. The longitudinal section of the mating seat and each partition rod is preferably a triangular structure so that the water droplets and moisture that drip and slide down from the stacked waste wires are introduced into each second drain hole 111, ensuring the drainage effect of the collection bucket 11.

[0039] like Figure 1 , Figure 8As shown, the collection base 14 includes a support body 144 and a rotating disk 145. The rotating disk 145 has several mounting ports 141, each of which can hold a collection bucket 11. A rotating assembly 146 is provided between the support body 144 and the rotating disk 145 to control the rotation of the rotating disk 145. That is, by rotating the rotating disk 145, a new collection bucket 11 can be matched with the guide pipe 22. Specifically, when the pressure sensor 13 located below the collection bucket 11 detects that a certain amount of waste wire has been collected in the collection bucket 11, it will send control signals to the cutting structure 12 and the rotating assembly 146 in sequence. After the cutting structure 12 has finished cutting the waste wire, the rotating assembly 146 controls the rotating disk 145 to rotate, completing the replacement of the collection bucket 11. The rotating assembly 146 mainly includes a rotating gear 1461, a drive gear 1462, and a drive motor 1463. The output shafts of the drive gear 1462 and the drive motor 1463 are linked together and mesh with the rotating gear 1461. The support base 144 is provided with a motor mount for fixing the drive motor 1463 to ensure that the drive motor 1463 can stably provide driving force. The rotating gear 1461 and the rotating disk 145 are integrally formed to ensure the reliability of the connection between the two and to enable the rotating disk 145 to rotate under the action of the gear transmission structure. With the constant transmission ratio of the gear transmission, the rotating disk 145 can be rotated by a specified angle (such as the included angle between adjacent mounting ports) under the drive of the drive motor 1463, ensuring the stability and accuracy of the replacement of the collection bucket 11.

[0040] like Figure 4 As shown, the collection base 14 is provided with a water storage tank 147, and a water storage box 3 is provided in the water storage tank 147. The water storage box 3 is slidably connected to the collection base 14, and the water storage box 3 is interconnected with the drain outlet 142. Specifically, the water storage tank 147 is fixedly opened below the outlet of the guide pipe 22 of the rotating disc 145. That is, as the rotating disc 145 rotates, only the drain outlet 142 located directly below the outlet of the guide pipe 22 is interconnected with the water storage box 3 located in the water storage tank 147. With the presence of the water storage box 3, water droplets dripping from the collection bucket 11 are collected.

[0041] The water storage tank 3 should be equipped with a handle so that the staff can pull the water storage tank 3 and make the water storage tank 3 slide out of the support body 144 when the water inside the water storage tank 3 is about to overflow, so that the water storage tank 3 can be poured out and then reset or directly replaced.

[0042] The axial length of the rotating disc 145 is greater than the axial length of the rotating gear 1461. The support base 144 is provided with a rotating hole 1441. The diameter of the rotating hole 1441 is smaller than the diameter of the rotating gear 1461. That is, the longitudinal section of the rotating disc 145 is a stepped shaft structure. The rotating hole 1441 is located between the rotating gear 1461 and the water storage tank 3. With the presence of the rotating hole 1441, the water overflowing from the water storage tank 3 can be effectively prevented from contacting the rotating gear 1461, and the water droplets generated when the water droplets fall can be prevented from splashing out from the tooth gap of the rotating gear 1461, thus ensuring the water flow and water droplet collection effect of the water storage tank 3.

[0043] If necessary, the inlet of the guide pipe 22 extends through the rotating disc 145 along its axial direction, allowing the water flow generated by the high-pressure water jet loom to be directly discharged from the guide pipe 22 upon entering it. A water collection tank is provided below the inlet of the guide pipe 22, allowing the water flow discharged directly from the inlet of the guide pipe 22 to enter the water collection tank. A water guide frame can be provided below the guide pipe 22 to collect water droplets leaking from each of the first leakage holes 223. The water guide frame is inclined below the guide pipe 22, with the horizontal height of the end of the water guide frame closer to the water collection tank being lower than the horizontal height of the end of the water guide frame farther from the water collection tank. This allows the water flowing out of each of the first leakage holes 223 to be guided into the water collection tank by the water guide frame, preventing water from falling onto the workshop floor and polluting the workshop.

[0044] The cutting structure 12 is fixedly installed on the guide pipe 22 and located at one end of the guide pipe 22 close to the collection bucket 11. In this way, it is not necessary to install the cutting structure 12 on each collection bucket 11, which not only reduces the operating cost of this embodiment, but also reduces the operating load when the rotating component 146 controls the rotating disk 145 to rotate.

[0045] like Figure 6 As shown, the cutting structure 12 includes a cutting blade 121, a cutting seat 122, and a moving component 123 for driving the cutting blade 121 to move. The cutting seat 122 is fixedly connected to the guide pipe 22. Specifically, a fixing plate is provided at one end of the guide pipe 22 close to the cutting seat 122. The fixing plate is provided with several connecting holes, and several second threaded parts are provided between the fixing plate and the cutting seat 122 to fix the two together.

[0046] In this embodiment, both the first threaded component and the second threaded component are preferably standard parts such as bolts commonly available on the market, so that a substitute can be quickly found if they are accidentally lost.

[0047] The cutting blade 121 is slidably connected to the cutting base 122. The moving assembly 123 mainly includes a drive screw, a moving block, and a moving motor. The cutting blade 121 is fixedly connected to the moving block, which is driven by the drive screw. The drive screw is rotatably connected to the cutting base 122 and is linked to the output shaft of the moving motor. In this embodiment, the cutting blade 121 is controlled to move and cut waste edges by a screw drive, effectively ensuring the stability and reliability of the cutting work. The moving motor should be fixedly connected to the cutting base 122 to ensure that the moving motor can stably provide driving force.

[0048] Preferably, the drive screw is a double-ended screw, and there are two cutting blades, each located at one end of the drive screw, so that the cutting structure 12 in this embodiment can perform bidirectional shearing of waste edge fibers, effectively avoiding fiber pulling residue during single-blade shearing.

[0049] In this embodiment, the moving motor and drive motor 1463 are preferably high-precision motors such as servo motors to ensure the accuracy of the movement of the cutting blade 121 and the rotating disk 145.
