Description

Technical Field

[0001] The present application relates to the technical field of waste yarn treatment, and particularly to a waste yarn collection device for an air-jet loom. Background Art

[0002] A textile machine is an indispensable production equipment in textile production.

[0003] Currently, a Chinese patent with the authorization announcement number CN204491136U discloses a central waste yarn collection system, belonging to the textile technology field. This central waste yarn collection system includes a negative pressure fan, a waste yarn collection box, a main air duct, and several branch air ducts. A yarn blocking net is provided in the waste yarn collection box and is connected to the main air duct. The negative pressure fan is arranged in a fan box, and the fan box is connected to the waste yarn collection box through a filter pipeline. A linen cloth net for secondary filtration is also provided in the filter pipeline. A hatch for opening is provided on the side of the waste yarn collection box. The branch air ducts are connected to the main air duct, pass through the floor and extend into the lower textile workshop. A conical dust collection hood is connected to the lower end of the branch air duct, and the hood opening of the dust collection hood faces the hosiery machines in the workshop.

[0004] When the negative pressure fan forms negative pressure to extract waste yarn, the waste yarn may adhere to the yarn blocking net. When the waste yarn adheres to the yarn blocking net, negative pressure cannot be generated in the waste yarn collection box, resulting in the waste yarn collection box being unable to extract the waste yarn in the main air duct well, and thus the waste yarn cannot be collected well. Summary of the Utility Model

[0005] In order to ensure the waste yarn collection effect, the present application provides a waste yarn collection device for an air-jet loom.

[0006] The waste yarn collection device for an air-jet loom provided by the present application adopts the following technical solutions:

[0007] A waste yarn collection device for a jet loom, comprising a main pipeline, branch pipelines, a collection box, a negative pressure component and a blocking mechanism. The branch pipelines are arranged on the main pipeline, and the branch pipelines correspond to the positions where waste is generated. A collection cavity is formed in the collection box, and the main pipeline is connected to the collection box. The negative pressure component is arranged on the collection box. A collection port is formed in the collection box, and the blocking mechanism is arranged on the collection box and covers the collection port. The device further comprises a partition block and a scraping mechanism. The partition block is arranged on the collection box and divides the collection cavity into a first cavity and a second cavity. A first through hole communicating the first cavity and the second cavity is formed in the partition block. The main pipeline is communicated with the first cavity, the negative pressure component is communicated with the second cavity, and the collection port is communicated with the first cavity. The scraping mechanism comprises a scraping block and a first adjustment component. The scraping block is slidably arranged in the first cavity and abuts against the partition block. The first adjustment component is arranged on the collection box and is connected to the scraping block.

[0008] By adopting the above technical solution, under the action of the negative pressure component, negative pressure will be formed in the first cavity and the second cavity. Waste yarn enters the first cavity through the branch pipelines and the main pipeline. When waste yarn adheres to the partition block and affects the generation of negative pressure in the first cavity, start the first adjustment component. The first adjustment component drives the scraping block to move, and the scraping block will drive the waste yarn adhering to the partition block to move, so that the waste yarn moves to one end of the partition block. Therefore, the arranged scraping mechanism can change the position of the waste yarn on the partition block, thereby reducing the situation that the formation of negative pressure in the first cavity is affected by the waste yarn, and thus ensuring the waste yarn collection effect.

[0009] Optionally, the first adjustment component comprises a first screw rod and a first motor. The first screw rod passes through the scraping block and is threadedly connected to the scraping block. The first motor is arranged on the collection box and is connected to the first screw rod.

[0010] By adopting the above technical solution, start the first motor. The output shaft of the first motor drives the first screw rod to rotate, and the first screw rod drives the scraping block to move, and the scraping block will scrape the waste yarn adhering to the partition block.

[0011] Optionally, a dredging mechanism is arranged on the second cavity. The dredging mechanism comprises a movable block, a dredging block and a second adjustment component. The movable block is slidably arranged in the second cavity. The dredging block is arranged on the movable block and corresponds to the first through hole. The second adjustment component is arranged on the collection box and is connected to the movable block.

[0012] By adopting the above technical solution, before the scraping block scrapes the waste yarn attached to the partition block, the second adjusting component is first started, so that the second adjusting component drives the moving block to move, and the moving block drives the dredging block to move towards the partition block, so that the dredging block ejects the waste yarn in the first through hole, and can reduce the phenomenon that the waste yarn enters the first through hole when the scraping block scrapes the waste yarn.

[0013] Optionally, the second adjusting component includes a second screw rod and a second motor, the second screw rod passes through the moving block and is threadedly connected to the moving block; the second motor is arranged on the...

[0014] By adopting the above technical solution, the second motor is started, the output shaft of the second motor drives the second screw rod to rotate, and the second screw rod drives the moving block to move.

[0015] Optionally, there are two collecting boxes, and a feed pipe connecting the collecting box and the main pipe is arranged on each collecting box, and the feed pipe communicates with the first cavity; a blocking component is arranged on the feed pipe.

[0016] By adopting the above technical solution, when the scraping block scrapes the waste yarn attached to the partition block, another collecting box is used to collect the waste yarn, and the scraping block scrapes the partition block in the collecting box that has not collected the waste yarn; in this way, the extraction of the waste yarn can be maintained continuously; when the scraping block scrapes the waste yarn, the blocking component blocks the channel of the feed pipe to prevent the waste yarn from entering this collecting box again, reducing the situation where the scraping block cannot return to its original position.

[0017] Optionally, the blocking component includes a rotating shaft, a blocking block and a third motor, the rotating shaft is rotatably arranged on the feed pipe, the blocking block is arranged on the rotating shaft and can block the channel of the feed pipe; the third motor is arranged on the feed pipe and is connected to the rotating shaft.

[0018] By adopting the above technical solution, the third motor is started, the output shaft of the third motor drives the rotating shaft to rotate, and the rotating shaft drives the blocking block to move.

[0019] Optionally, the blocking mechanism includes a blocking block and a third adjusting component, the blocking block is slidably arranged on the collecting box and covers the collecting port; the third adjusting component is arranged on the blocking block and is connected to the collecting box.

[0020] By adopting the above technical solution, when it is necessary to collect the waste yarn in the first cavity, the third adjusting component is started, and the third adjusting component drives the blocking block to move on the collecting box, so that the blocking block that originally covered the collecting port no longer covers the collecting port, and then the operator collects the waste yarn in the first cavity.

[0021] Optionally, the third adjustment component includes a fourth motor, an adjustment gear, and an adjustment rack. The fourth motor is disposed on the blocking block, and the adjustment gear is key-connected to the output shaft of the fourth motor; the adjustment rack is disposed on the collection box and meshes with the adjustment gear.

[0022] By adopting the above technical solution, when the fourth motor is started, the output shaft of the fourth motor drives the adjustment gear to rotate. Since the adjustment gear meshes with the fixed adjustment rack, the adjustment gear will displace relative to the adjustment rack, and thus the blocking block will move relative to the collection box.

[0023] Optionally, the negative pressure component includes a negative pressure fan and a negative pressure pipe. The negative pressure pipe connects the negative pressure fan and the collection box, and the negative pressure pipe communicates with the second cavity.

[0024] By adopting the above technical solution, when the negative pressure fan is started, a negative pressure is formed in the second cavity and the first cavity through the negative pressure pipe. The waste yarn generated by the textile machine enters the branch pipe, then enters the main pipe, and finally enters the first cavity in the collection box through the feed pipe.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0040] Referring to Figure 2 and Figure 3, a collection chamber is provided inside the collection box 13. The collection box 13 is fixedly connected with a partition block 3. The partition block 3 divides the collection chamber into a first cavity 131 and a second cavity 132. A first through hole 31 communicating the first cavity 131 and the second cavity 132 is provided on the partition block 3; the end of the feed pipe 15 far from the main pipe 11 communicates with the second cavity 132.

[0041] A negative pressure assembly 14 is connected to the collection box 13.

The end of the negative pressure pipe 142 far from the collection box 13 is connected with a negative pressure fan 141.

[0042] Start the negative pressure fan 141. A negative pressure is formed in the second cavity 132 and the first cavity 131 through the negative pressure pipe 142. The waste yarn generated by the textile machine enters the branch pipe 12, then enters the main pipe 11, and finally enters the first cavity 131 in the collection box 13 through the feed pipe 15.

[0043] Reference Figure 3 and Figure 4 , a first chute 134 communicating with the first cavity 131 is provided on the top wall of the collection box 13. A scraping mechanism 4 is provided on the collection box 13. The scraping mechanism 4 includes a first slider 43 slidably connected in the first chute 134. A scraping block 41 is fixedly connected to the first slider 43. The scraping block 41 abuts against the side wall of the partition block 3. A first adjusting assembly 42 is provided on the collection box 13. The first adjusting assembly 42 includes a first screw rod 421 rotatably connected in the first chute 134. The first screw rod 421 passes through the first slider 43 and is threadedly connected to the first slider 43; a first motor 422 is fixedly connected to the collection box 13. The output shaft of the first motor 422 is connected to one end of the first screw rod 421.

[0044] Start the first motor 422. The output shaft of the first motor 422 drives the first screw rod 421 to rotate. The first screw rod 421 drives the first slider 43 to slide in the first chute 134. The first slider 43 drives the scraping block 41 to move, and the scraping block 41 will drive the waste yarn attached to the partition block 3 to move.

[0045] Reference Figure 3 and Figure 4 , a protection assembly 7 is provided on the collection box 13. The protection assembly 7 includes a protection flexible plate 71. Protection flexible plates 71 are fixedly connected to both ends of the first slider 43; two fifth motors 73 are fixedly connected to the collection box 13. The first slider 43 is located between the two fifth motors 73. A winding shaft 72 is connected to the output shaft of the fifth motor 73. The end of the protection flexible plate 71 far from the first slider 43 is connected to the winding shaft 72. The two protection flexible plates 71 and the first slider 43 jointly cover the first chute 134.

[0046] When the first slider 43 moves, the fifth motor 73 is started simultaneously. The output shaft of the fifth motor 73 drives the winding shaft 72 to rotate, and the winding shaft 72 drives the protective flexible plate 71 to move, so that the protective flexible plates 71 on both sides of the first slider 43 are always in a certain state, thus reducing the waste yarn from entering the first chute 134.

[0047] Reference Figure 3 and Figure 5 As shown in FIGS. and, a second chute communicating with the second cavity 132 is formed in the collection box 13. A dredging mechanism 5 is arranged on the collection box 13. The dredging mechanism 5 includes a second slider 54 slidably connected in the second chute. A movable block 51 is fixedly connected to the second slider 54. A second through hole 511 misaligned with the first through hole 31 is formed in the movable block 51. A dredging block 52 is fixedly connected to one side of the movable block 51 close to the partition block 3. The dredging block 52 corresponds to the first through hole 31 and can enter the first through hole 31. A second adjusting assembly 53 is arranged on the collection box 13. The second adjusting assembly 53 includes a second screw rod 531 rotatably connected in the second chute. The second screw rod 531 passes through the second slider 54 and is threadedly connected to the second slider 54. A second motor 532 is fixedly connected to the collection box 13. The output shaft of the second motor 532 is connected to one end of the second screw rod 531.

[0048] When the scraping block 41 moves, the second motor 532 is started. The output shaft of the second motor 532 drives the second screw rod 531 to rotate. The second screw rod 531 drives the second slider 54 to move in the second chute in the direction close to the partition block 3. The second slider 54 drives the movable block 51 to move, and the dredging block 52 on the movable block 51 will enter the first through hole 31 of the partition block 3 and push out the waste yarn located in the first through hole 31.

[0049] Reference Figure 3 and Figure 6 As shown in FIGS. and, a collection port 133 communicating with the first cavity 131 is formed in the collection box 13. A blocking mechanism 2 is arranged on the collection box 13. The blocking mechanism 2 includes a blocking block 21 slidably connected to the collection box 13. The blocking block 21 can cover the collection port 133. A third slider is fixed on the blocking block 21. A third chute slidably connected to the third slider is formed in the collection box 13. A third adjusting assembly 22 connected to the blocking block 21 is arranged on the collection box 13. The third adjusting assembly 22 includes a fourth motor 221 fixedly connected to the blocking block 21. An adjusting gear 222 is key-connected to the output shaft of the fourth motor 221. An adjusting rack 223 meshing with the adjusting gear 222 is fixedly connected to the collection box 13.

[0050] Start the fourth motor 221. The output shaft of the fourth motor 221 drives the adjusting gear 222 to rotate. Since the adjusting gear 222 meshes with the fixed adjusting rack 223, the adjusting gear 222 will displace relative to the adjusting rack 223, and the blocking block 21 will move on the collection box 13.

[0051] The implementation principle of the waste yarn collection device of a jet loom in an embodiment of the present application is as follows: Initially, the blocking block 21 covers the collection port 133; the scraping block 41 is located at one end of the first cavity 131 away from the collection port 133; the passage of one of the feed pipes 15 is blocked by the blocking block 62, and the other feed pipe 15 is not blocked. The collection box 13 corresponding to the blocked feed pipe 15 is the first collection box 13, and the other collection box 13 is the second collection box 13. The branch pipe 12 corresponding to the non-operating loom is blocked by the blocking block 62.

[0052] Start the negative pressure fan 141 on the second collection box 13. Through the negative pressure pipe 142, a negative pressure is formed in the second cavity 132 and the first cavity 131. The waste yarn generated by the loom enters the branch pipe 12, then enters the main pipe 11, and finally enters the first cavity 131 in the collection box 13 through the feed pipe 15. After a period of time, turn off the negative pressure fan 141 on the second collection box 13 and start the third motor 63 on the feed pipe 15 of the second collection box 13 to block the feed pipe 15 on the second collection box 13 with the blocking block 62; before turning off the negative pressure fan 141 on the second collection box 13, first start the negative pressure fan 141 on the first collection box 13 and start the third motor 63 on the first collection box 13 so that the waste yarn can enter the first cavity 131 of the first collection box 13.

[0053] When the feed pipe 15 on the second collection box 13 is blocked, first start the second motor 532 to make the dredging block 52 push out the waste yarn located in the first through hole 31; then start the first motor 422 and the fifth motor 73. The first motor 422 moves the scraping block 41, and the scraping block 41 scrapes off the waste yarn attached to the partition block 3 and pushes the waste yarn located in the first cavity to the side close to the collection port 133; the fifth motor 73 keeps the two protective flexible plates 71 and the first slider 43 covering the first chute 134 all the time. Finally, make the movable block 51 and the scraping block 41 return to their initial positions.

[0054] In this way, the waste yarn alternately enters the first collection box 13 and the second collection box 13.

[0055] When enough waste yarn is collected in the first cavity 131 of the collection box 13, or within a specified time; first, turn off the negative pressure fan 141, and use the plugging block 62 to block the passage of the feed pipe 15. Then, start the second motor 532 first, so that the dredging block 52 ejects the waste yarn located in the first through hole 31; then start the fourth motor 221, so that the blocking block 21 no longer covers the collection port 133; then start the first motor 422 and the fifth motor 73, and the scraping block 41 drives the first waste yarn to move towards the direction close to the collection port 133, so that the operator can easily collect the waste yarn located in the first cavity 131.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
