Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for spinning equipment, and specifically to a nozzle assembly for cleaning plates. Background Technology

[0002] During the spinning process, high temperatures and the sublimation of some oligomers in the polymer melt produce white powder. This powder adheres to the spinneret of the spinning assembly. In addition, the silicone oil sprayed on the spinning spinneret before spinning cures and causes a lot of dirt to appear on the spinneret. This dirt will increase the number of broken ends and fuzz, affecting the production status. Therefore, the spinning spinneret must be cleaned after a period of time.

[0003] The commonly used method for cleaning the spinneret in the current technology is to spray a special atomized silicone oil onto the spinneret surface and then scrape the surface with a scraper. This method is time-consuming and labor-intensive, produces poor cleaning quality, and can easily damage the spinneret surface when scraping with a scraper. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a nozzle assembly for cleaning the spinneret that provides good cleaning quality and does not damage the spinneret surface.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A nozzle assembly for cleaning plates includes a robotic arm, a nozzle disposed at the end of the robotic arm, and a plate-sticking patter detachably disposed on the nozzle. The nozzle has a channel for the discharge of a cleaning medium. The nozzle has an operating state and a non-operating state. When the nozzle is in the operating state, the plate-sticking patter is detached from the nozzle, and the outlet of the channel is unobstructed. When the nozzle is in the non-operating state, the plate-sticking patter is disposed on the nozzle and blocks the outlet of the channel.

[0007] In some embodiments, the nozzle includes a housing disposed at the end of the robotic arm and a nozzle disposed in the housing, the channel being disposed within the nozzle, the channel including a constriction section and an expansion section, the constriction section being located within the housing, the expansion section partially extending to the outside of the housing, both the constriction section and the expansion section having a conical structure, and the small end of the constriction section and the small end of the expansion section being sequentially connected to form a throat.

[0008] In some embodiments, along the length extension direction of the channel, the length of the expansion segment is greater than the length of the contraction segment.

[0009] In some embodiments, the expansion segment is flat and has a square cross-section.

[0010] In some embodiments, the nozzle further includes an input conduit for the inflow of cleaning medium into the channel, the input conduit being in communication with the constriction section.

[0011] In some embodiments, the nozzle assembly further includes a clamping assembly disposed on the nozzle for clamping the sticky plate. The clamping assembly includes two clamping members, at least one of which is slidably disposed. Each clamping member is provided with a clamping portion for clamping the sticky plate. The two clamping portions are disposed opposite to each other, and a clamping space for clamping the sticky plate is formed between the two clamping portions.

[0012] In some embodiments, one of the two clamping members is slidably disposed in a direction away from and towards the other clamping member, and the clamping assembly further includes a first drive mechanism for driving the clamping member to slide.

[0013] In some embodiments, the sticky plate is rotatably mounted on the clamping assembly about its own axis, and the nozzle assembly further includes a second drive mechanism for driving the sticky plate to rotate about its own axis.

[0014] In some embodiments, the second drive mechanism includes a first gear rotatably disposed within the nozzle, a second gear rotatably disposed within the nozzle, a turntable fixedly connected to the second gear, and a motor for driving the first gear to rotate, wherein the first gear meshes with the second gear, and the clamping assembly is disposed on the turntable.

[0015] In some embodiments, the nozzle includes a nozzle head, the channel is formed on the nozzle head, the clamping assembly and the turntable are both provided with openings at positions corresponding to the nozzle head, and one end of the nozzle head is located in the opening.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: When cleaning the spinneret surface, the nozzle assembly of this utility model can automatically adjust the position of the nozzle by means of a robotic arm to move it to the position of the spinneret surface. After the nozzle sprays the cleaning medium onto the spinneret surface in the working state, the nozzle is put into a non-working state, and the spinneret surface is wiped by the sticky plate set on the nozzle, so as to quickly remove dirt, oil, residual impurities, etc. from the spinneret surface, which can effectively improve the cleaning quality, and ultimately improve product quality and production efficiency. Moreover, this cleaning method will not damage the spinneret surface. Attached Figure Description

Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figure 1 and Figure 2 As shown, the nozzle assembly for cleaning boards of this utility model includes a robotic arm 1, a nozzle 2, and a board-sticking plate 3.

[0031] Nozzle 2 is mounted on robotic arm 1, which has multiple degrees of freedom. The position of nozzle 2 is adjusted by the movement of robotic arm 1 so that it moves to the position of spinneret to clean the spinneret.

[0032] like Figures 4-9 As shown, nozzle 2 includes a housing 21 and a nozzle 22. The housing 21 is located at the end of the robotic arm 1 and has a receiving cavity. The nozzle 22 is mounted on the housing 21, with most of it located within the receiving cavity of the housing 21. The nozzle 22 sprays the cleaning medium onto the spinneret surface. The cleaning medium can be solid, liquid, or gaseous, or a mixture of two or three of these states.

[0033] Specifically, such as Figure 6 and Figure 8 As shown, the nozzle 22 has a channel for the cleaning medium to flow out. The channel includes a converging section 221 and an expanding section 222 arranged sequentially. The converging section 221 is located within the accommodating cavity of the housing 21, and the expanding section 222 extends partially to the outside of the housing 21. Both the converging section 221 and the expanding section 222 have a conical structure, with the small end of the converging section 221 and the small end of the expanding section 222 connected sequentially to form a throat 223. After the cleaning medium enters the channel within the nozzle 22, it first enters the converging section 221. After being converged by the converging section 221, the flow velocity of the cleaning medium in the channel increases. After being expanded by the expanding section 222, the flow velocity further increases, forming a high-speed jet that is ejected onto the spinneret surface. The impact force generated by the high-speed jet continuously and powerfully washes the spinneret surface, peeling off and rinsing off any adhering substances, thus achieving a cleaning effect.

[0034] In this embodiment, the expansion section 222 is relatively long along the length of the channel, and its length is greater than that of the contraction section 221. The expansion section 222 is also flat, which ensures that the cleaning medium is sprayed onto the spinneret surface at a specific angle and direction to improve the cleaning effect. In this embodiment, the cross-section of the expansion section 222 is square.

[0035] The nozzle 2 also includes an inlet pipe 23, which is disposed on the nozzle head 22 and is connected to the converging section 221. The inlet pipe 23 is used to connect to an external pipeline so that the cleaning medium used for cleaning the plate can flow into the channel of the nozzle head 22.

[0036] The adhesive plate 3 is used to wipe away dirt from the spinneret surface. The adhesive plate 3 is detachably mounted on the nozzle 2. Specifically, the nozzle 2 has an operating state and a non-operating state. When the nozzle 2 is in the operating state, the adhesive plate 3 is detached from the nozzle 2, and the outlet of the nozzle 22 channel is unobstructed. At this time, cleaning media can be sprayed onto the spinneret surface through the nozzle 2, such as... Figure 2 and Figure 3 As shown. When nozzle 2 is not in operation, the adhesive plate 3 is placed on nozzle 2 and blocks the outlet of the nozzle 22 channel. At this time, the adhesive plate 3 is pressed against the spinneret surface, and the adhesive plate 3 wipes away the dirt on the spinneret surface. At the same time, due to the blocking effect of the adhesive plate 3, dirt is also prevented from entering the nozzle 22 channel. Figure 1 As shown.

[0037] The nozzle assembly also includes a clamping assembly that detachably mounts the adhesive plate 3 onto the nozzle 2. The clamping assembly is mounted directly or indirectly onto the nozzle 2. Specifically, the clamping assembly includes two clamping members 4, at least one of which is slidably mounted relative to the nozzle 2.

[0038] Each clamping member 4 includes a support portion 41 and a clamping portion 42 disposed on the support portion 41. The support portion 41 supports the sticky plate 3. The clamping portion 42 clamps the sticky plate 3. The clamping portions 42 on the two clamping members 4 are disposed opposite each other, forming a clamping space between the two clamping portions 42. When the sticky plate 3 is clamped by the clamping assembly, the sticky plate 3 is placed on the two support portions 41, and at least one clamping member 41 slides relative to the nozzle 2 in a direction that brings the clamping portion 42 closer to the clamping space, so that the two clamping portions 42 respectively abut against the opposite sides of the sticky plate 3, thereby clamping the sticky plate 3 in the clamping assembly. When at least one clamping portion 42 slides away from the clamping space, the clamping assembly releases the sticky plate 3, and the sticky plate 3 can be removed from the nozzle 2.

[0039] In this embodiment, the support part 41 is a flat plate structure, and the clamping part 42 is disposed on the outer periphery of the support part 41. The clamping part 42 is adapted to the sticky plate 3. For example, the cross-section of the sticky plate 3 is circular, and the clamping part 42 is an arc-shaped plate.

[0040] The support part 41 is provided with an opening that matches the nozzle 22 at the position corresponding to the nozzle 22. The opening penetrates both ends of the support part 41 in the thickness direction. The nozzle 22 is located in the opening, and the outer end of the nozzle 22 is not higher than the outer end face of the support part 41. Here, the outer end face refers to the end face away from the housing 21.

[0041] In this embodiment, of the two clamping members 4, one clamping member 4 is fixedly disposed relative to the other clamping member 4, and the other clamping member 4 slides away from the fixed clamping member 4.

[0042] The clamping assembly also includes a first drive mechanism for driving a clamping member 4 to slide. In this embodiment, as... Figure 9 As shown, the first driving mechanism includes a cylinder 5, and the slidable clamping member 4 further includes a first connecting part 43 disposed at the bottom of the support part 41, the first connecting part 43 being connected to the piston rod of the cylinder 5. When the piston rod extends or retracts, it can drive the clamping member 4 connected thereto to slide.

[0043] Of course, both clamping parts 4 can also slide relative to the nozzle 2. For example, the two clamping parts 4 can slide towards each other simultaneously, thus getting closer to each other to clamp the sticky plate 3. The two clamping parts 4 can also slide away from each other simultaneously, thus moving away from each other to release the sticky plate 3 and allow the sticky plate 3 to detach from the nozzle 2.

[0044] At this time, the first drive mechanism includes a gripper cylinder, which includes a cylinder body and two grippers that can slide simultaneously towards and away from each other. Each gripper 4 also includes a first connecting part 43 disposed at the bottom of the support part 41, and the two first connecting parts 43 are respectively connected to the two grippers one by one.

[0045] The adhesive plate 3 can also be rotatably mounted on the clamping assembly around its own axis. When wiping the dirt on the spinneret surface with the adhesive plate 3, the adhesive plate 3 can be rotated to improve its cleaning effect.

[0046] The nozzle assembly also includes a second drive mechanism for driving the sticky plate 3 to rotate about its own axis.

[0047] like Figure 10As shown, the second drive mechanism includes a first gear 61 rotatably disposed within the housing 21, a second gear 62 rotatably disposed within the housing 21, a turntable 63 fixedly connected to the second gear 62, and a motor 64 driving the first gear 61 to rotate. The first gear 61 meshes with the second gear 62. The turntable 63 is rotatably disposed outside the housing 21. One clamping member 4 is fixedly disposed on the turntable 63, and another clamping member 4 is slidably disposed on the turntable 63.

[0048] When the motor 64 starts, it drives the first gear 61 to rotate. Through the meshing of the first gear 61 and the second gear 62, the second gear 62 rotates with the first gear 61, thereby driving the turntable 63 to rotate. This causes the clamping assembly set on the turntable 63 to rotate, thereby driving the sticky plate 3 to rotate.

[0049] In this embodiment, the first gear 61 is a pinion and the second gear 62 is a large gear.

[0050] An opening is also provided at the position of the rotary table 63 corresponding to the nozzle 22. One end of the nozzle 22 passes through the opening on the rotary table 23 and extends into the opening of the clamping member 4.

[0051] In this embodiment, a second connecting part 211 is fixedly provided at the bottom of the housing 21 and is fixedly connected to the end of the robotic arm 1. The second connecting part 211 has a mating part adapted to the end of the robotic arm 1. The mating part is engaged at the end of the robotic arm 1, and the second connecting part 211 is connected to the end of the robotic arm 1 by fasteners. This arrangement makes the connection between the nozzle 2 and the robotic arm 1 more reliable, so as to precisely control the position of the nozzle 2 through the movement of the robotic arm 1.

[0052] The nozzle assembly also includes a controller. The robotic arm 1, the first drive mechanism, and the second drive mechanism are all electrically connected to the controller so as to control the movement of the robotic arm 1, the first drive mechanism, and the second drive mechanism through the controller.

[0053] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
