Description

Technical Field

[0001] This utility model relates to the field of stretching device technology, specifically a stretching device for a wire drawing machine. Background Technology

[0002] A wire drawing machine is a device that heats and melts plastic resin raw materials, extrudes monofilaments through the spinneret of the die head into a cold water tank for cooling, then enters a hot water tank for heating and stretching, and finally winds them into an I-beam or straight tube according to the required number of heads. A stretching device is required when stretching monofilaments.

[0003] Existing wire drawing machines use a stretching device where the monofilament is processed starting from the upper left rotating roller and ending from the upper right rotating roller. Since these two points lack limiting functions, the filament easily shifts and falls out of the slot during processing, increasing the adjustment burden on operators. Related technologies place the monofilament into the slot of the rotating roller, and the rotating roller and spring can adaptively compress and limit the filament, preventing it from falling off during processing and reducing the operator's workload. However, the limiting roller is in continuous contact with the monofilament, and the constant friction during this contact can cause unevenness on the surface of the limiting roller, affecting the quality of wire drawing. Furthermore, the limiting roller's limiting seat is fixed to one side of the device, making it difficult to disassemble and replace the limiting roller, resulting in inconvenience.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a stretching device for a wire drawing machine, which has the following advantages:

[0017] In use, this invention simply requires the monofilament to pass through the space between the limiting wheel and the traction roller, through several traction rollers, and then out from one side of the end traction roller. The monofilament is sequentially fed from the low-speed traction roller to the high-speed traction roller. Because the high-speed traction roller rotates too fast, the low-speed traction roller cannot keep up with the speed of the traction roller, which will stretch the monofilament between the two. The two limiting wheels will limit the movement of the monofilament, preventing it from detaching from the traction roller. This is convenient and quick. At the same time, when it is necessary to replace the limiting wheel, simply adjust the connecting seat upwards to drive the insert plate into the insertion hole, and then pull the two unlocking plates to unlock the limiting wheel, so that the limiting wheel can be disassembled. This is convenient and quick. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0028] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0030] When using the equipment, after centrifugation, the operator removes the centrifuge tube, transfers the supernatant from the centrifuge tube to the lab bench, and then takes the supernatant back to the centrifuge for centrifugation. This process is repeated three times, followed by ultracentrifugation.

[0031] In related technologies, a lifting disc is installed inside the centrifuge device. By lifting the lifting disc upwards, the centrifuge tubes are pushed upwards from inside the separation device, and the top of the centrifuge tubes is moved upwards, making it easier to pick up the centrifuge tubes. However, the function of this lifting disc is relatively simple, and when using ultracentrifugation, centrifugation is required in three stages, and the supernatant needs to be collected after each centrifugation. The desktop test tube rack is far away and has no fixing device. If it is accidentally bumped during the extraction, the centrifuged material may be spilled, which will affect the extraction efficiency.

[0032] To address some of the problems in related technologies, this application provides an exosome separation and extraction device. In use, the monofilament simply passes between the limiting wheel 25 and the traction roller 12, through several traction rollers 12, and then exits from one side of the end traction roller 12. The filament is sequentially fed from the low-speed traction roller 12 to the high-speed traction roller 12. Because the high-speed traction roller 12 rotates too fast, the low-speed traction roller 12 cannot keep up with the filament's pace, stretching the filament between them. The two limiting wheels 25 then limit the movement of the monofilament, preventing it from detaching from the traction roller 12. This is convenient and quick. Furthermore, when the limiting wheel 25 needs to be replaced, simply adjust the connecting seat 23 upwards to insert the insertion plate 242 into the insertion hole 244, and then pull the two unlocking plates 264 to unlock the limiting wheel 25, allowing for easy and quick disassembly.

[0033] This application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figures 1-4 This application provides a stretching device for a wire drawing machine, including: a fixed base 11 with a traction roller 12 mounted on one side; a moving component 2 is disposed inside the fixed base 11; the moving component 2 includes: a drive motor 21, mounted on the top of the fixed base 11, and a lead screw fixedly connected to the output end of the drive motor 21; an adjusting base 22, threadedly connected to the outside of the lead screw; a connecting base 23, fixedly connected to the top of the adjusting base 22; a pushing mechanism 24, disposed on the top of the connecting base 23 and the fixed base 11; a limiting wheel 25, mounted on one side of the connecting base 23; and an installation mechanism 26, disposed inside the connecting base 23, with the limiting wheel 25 connected to the connecting base 23 through the installation mechanism 26.

[0035] In use, the monofilament is passed through the space between the limiting wheel 25 and the traction roller 12. The motor on one side of the traction roller 12 is started, driving the traction roller 12 to rotate and feed the monofilament. The monofilament is fed sequentially from the low-speed traction roller 12 to the high-speed traction roller 12. Because the high-speed traction roller 12 rotates too fast, the low-speed traction roller 12 cannot feed the filament in time, which will stretch the filament between the two. The distance between the two limiting wheels 25 and the traction roller 12 is slightly smaller than the diameter of the monofilament, so the limiting wheels 25 rotate when the monofilament moves. The two sides of the limiting wheels 25 have a larger diameter, and the limiting wheels 25 pass through the larger diameter... To prevent the monofilament from sliding left and right on the traction roller 12, thus preventing the monofilament from detaching from the traction roller 12, this method is convenient and quick. At the same time, when it is necessary to replace the limiting wheel 25, simply drive the lead screw of the drive motor 21 to adjust the connecting seat 23 upward, drive the insert plate 242 to insert into the insertion hole 244, thereby driving the two baffles 243 to move in opposite directions, thus exposing the two unlocking plates 264. Then, pull the two unlocking plates 264 to pull the mounting slider 263 out of the side groove of the mounting head 261, releasing the limitation on the limiting wheel 25, and the limiting wheel 25 can be disassembled, which is convenient and quick.

[0036] In some embodiments, the pushing mechanism 24 includes: a fixing block 241 fixedly connected to the top of the fixing seat 11, with a through slot formed below the fixing block 241 and located at the top of the fixing seat 11; an insert plate 242 fixedly connected to the bottom of the fixing block 241; a baffle 243 slidably connected to the top of the connecting seat 23; an insertion hole 244 formed at the top of the connecting seat 23; a pushing inclined surface 245 disposed on one side of the baffle 243; and a first guide rod 246 fixedly connected to the inside of the connecting seat 23, with the first guide rod 246 slidably connected to both sides of the baffle 243, and a spring sleeved on the outside of the first guide rod 246.

[0037] When the connector 23 moves upward, the insertion hole 244 at the top of the connector 23 will be inserted by the insertion plate 242 at the bottom of the fixing block 241. During the insertion of the insertion hole 244, the inclined surfaces 245 on both sides will be pressed first, thereby pushing the baffle 243 to move away from each other. When the insertion plate 242 is fully inserted into the insertion hole 244, the baffle 243 at the top of the connector 23 will be fully opened, exposing the mounting mechanism 26 inside, which facilitates subsequent operations.

[0038] In some embodiments, the through slot at the bottom of the fixing block 241 and at the top of the fixing seat 11 is the same size and shape as the connecting seat 23, so that the connecting seat 23 can rise with the adjusting seat 22 and slide along the through slot to the position of the fixing block 241, thereby unlocking the two baffles 243.

[0039] In some embodiments, the size and shape of the socket 244 are the same as those of the insert plate 242, which facilitates the insertion of the insert plate 242 into the socket 244, thereby pressing the two push ramps 245.

[0040] In some embodiments, the mounting mechanism 26 includes: a mounting head 261, fixedly connected to one end of the limiting wheel 25; a mounting base 262, fixedly connected to the interior of the connecting base 23; a mounting slider 263, slidably connected to the interior of the mounting base 262; an unlocking plate 264, fixedly connected to the top of the mounting slider 263; and a second guide rod 265, fixedly connected to the interior of the mounting base 262, the second guide rod 265 being slidably connected to both sides of the mounting slider 263, and a spring being sleeved on the outside of the second guide rod 265.

[0041] In use, when it is necessary to disassemble the limiting wheel 25, simply pull the two unlocking plates 264 to pull the two mounting sliders 263 out from one side of the mounting head 261, thereby releasing the limitation on the mounting head 261 and the limiting wheel 25. Pulling the limiting wheel 25 will then remove it. When it is necessary to install a new limiting wheel 25, simply align the mounting head 261 at one end of the limiting wheel 25 with the groove inside the connecting seat 23. During the movement, the mounting head 261 will press one side of the mounting slider 263, thereby pulling the mounting slider 263 into the interior of the mounting seat 262. After the mounting head 261 is fully inserted into the groove, the mounting slider 263 will be pushed into the groove on one side of the mounting head 261 under the action of the spring, thereby limiting the limiting wheel 25 and facilitating operation.

[0042] In some embodiments, one side of the mounting slider 263 extends into the interior of the mounting base 262, the extended portion is provided with a slope, and one side of the mounting head 261 is provided with a groove of the same size and shape as the extended portion of the mounting slider 263, so that when the mounting head 261 slides into the interior of the connecting base 23, it can press the slope and retract the mounting slider 263 into the interior of the mounting base 262.

[0043] In some embodiments, support components 3 are provided at the four corners of the fixed base 11; the support components 3 include: a support base 31, which is disposed below the fixed base 11 and whose bottom is in contact with the ground; a threaded rod 32, which is threaded to the four corners of the fixed base 11 and whose bottom is fixedly connected to the top of the support base 31; and an adjustment head 33, which is fixedly connected to the top of the threaded rod 32 to facilitate adjustment of the fixed base 11 to adapt to different working environments.

[0044] In some embodiments, a water droplet leveler is provided on one side of the fixed base 11 and between the support bases 31 to facilitate observation of whether the fixed base 11 has been leveled.

[0045] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0046] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
