Description

Technical Field

[0001] This invention belongs to the field of elastic energy storage technology, and particularly relates to an elastic line tension and deformation limiter. Background Technology

[0002] Elastic energy storage devices typically utilize elastic elements that are stretched or compressed to store elastic potential energy. Because elastic wires have good deformation capabilities and their length is less restricted during production, they can be manufactured to the required length. Furthermore, under tension, the length of an elastic wire can be several times its initial length, resulting in excellent energy storage performance. However, the elastic wire needs protection during energy storage to prevent breakage due to excessive tension. Therefore, adjustments must be made based on the tension and deformation state of the elastic wire during energy storage to prevent breakage. Currently, no such equipment is publicly available on the market. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide an elastic wire tension and deformation limiter that is simple in structure, easy to use, and can detect the elastic wire online.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] An elastic wire tension and deformation limiter, comprising:

[0006] Mounting rack;

[0007] The fixed roller is rotatably mounted on the mounting frame;

[0008] A carriage, slidably mounted on the mounting bracket, is slidable to move closer to or further away from the fixed roller; a movable roller, rotatably mounted on the carriage and parallel to the fixed roller; and

[0009] An adjustment mechanism is mounted on the mounting bracket, and its drive end is connected to the slide.

[0010] The elastic thread passes through and is clamped between the fixed roller and the movable roller for conveying. The adjustment mechanism is used to adjust the carriage to move the movable roller closer to or further away from the fixed roller, so as to adjust the deformation and frictional resistance at the clamping point of the elastic thread.

[0011] The beneficial effects of the above technical solution are as follows: When a fixed tension is applied to the elastic thread, the movable roller and the fixed roller clamp the elastic thread, applying resistance to the tension. Under this tension, the elastic thread will be stretched and store energy. The degree to which the movable roller and the fixed roller clamp the elastic thread determines the magnitude of the resistance between them. The resistance to the tension can be adjusted by changing the distance between the movable roller and the fixed roller. This allows the distance between the movable roller and the fixed roller to be adjusted according to the required specifications of the elastic thread to meet the needs of energy storage, preventing the elastic thread from breaking during energy storage and thus protecting the elastic thread during energy storage.

[0012] The mounting frame described in the above technical solution includes a beam and two slide rods. The two slide rods are parallel to each other and spaced apart. The beam is arranged laterally and connected to the same end of the two slide rods. The fixed roller and the movable roller are both arranged laterally between the two slide rods. The two ends of the fixed roller are rotatably connected to the ends of the two slide rods away from the beam. The slide frame is slidably connected to the two slide rods. The movable roller is located between the beam and the fixed roller, and its two ends are rotatably connected to the slide frame.

[0013] The advantages of the above technical solution are: its structure is simple, and it makes the fixed roller more stable on the mounting frame, while the movable roller is more convenient to slide on the mounting frame.

[0014] The slide in the above technical solution includes a connecting rod and two connecting plates. The two connecting plates correspond one-to-one with the two slide rods. Each connecting plate is slidably disposed on the corresponding slide rod and located between the movable roller and the beam rod. The connecting rod is arranged laterally, and its two ends are connected to the ends of the two connecting plates near the beam rod. The two ends of the movable roller are rotatably connected to the other ends of the two connecting plates. The connecting rod is connected to the drive end of the adjustment mechanism.

[0015] The advantages of the above technical solution are: its structure is simple, and the two connecting plates can move synchronously on the mounting frame under the action of the connecting rod, so that the movable roller can always remain parallel to the fixed roller when sliding.

[0016] In the above technical solution, the middle of each of the two slide rods is provided with a horizontally penetrating and straight-strip-shaped sliding hole along its length direction. The two connecting plates are respectively located on the side of the two slide rods that are far apart from each other. The two ends of the connecting rod pass through the two sliding holes and are connected to the connecting plates. The two ends of the movable roller pass through the sliding holes and are rotatably connected to the two connecting plates.

[0017] The advantages of the above technical solution are: its structure is simple, which allows the two sliding holes to limit and guide the movable roller and the connecting rod, thus eliminating the need for a complex structure to achieve the sliding connection between the carriage and the mounting frame.

[0018] The adjustment mechanism described in the above technical solution includes an adjustment component, a guide rod, and a first spring. One end of the guide rod is perpendicularly connected to the connecting rod, and the other end is provided with a limit block. The guide rod is slidably connected to the beam rod. The first spring is sleeved on the guide rod, and its two ends abut against the limit block and the beam rod, respectively. The adjustment component is mounted on the mounting frame, and its driving end is connected to the guide rod. It is used to adjust the sliding of the guide rod relative to the beam rod to adjust the distance between the fixed roller and the movable roller. The elastic force of the first spring is used to drive the guide rod to move the movable roller away from the fixed roller.

[0019] The beneficial effects of the above technical solution are as follows: its structure is simple, so that the driving end of the adjusting member only needs to contact the end of the limiting block away from the guide rod. Only when the adjusting member overcomes the elastic force of the first spring to squeeze the guide rod to move towards the fixed roller, the distance between the fixed roller and the movable roller decreases. When the driving member of the adjusting member retracts, the guide rod drives the movable roller to move away from the fixed roller under the elastic force of the first spring, and the displacement of the movable roller is consistent with the retraction amount of the driving end of the adjusting member.

[0020] In the above technical solution, the guide rod is an adjustable rod. The adjusting component includes a support column, a lever, a lower pressure head, a male connector, and a female connector. The support column and the female connector are both located on the side of the beam rod away from the slide. The sliding connection between the guide rod and the beam rod is located between the support column and the female connector. One end of the lever is rotatably connected to the end of the support column away from the beam rod. The male connector is installed on the other end of the lever. One end of the lower pressure head is rotatably connected to the middle of the lever. The limiting block has a limiting groove recessed at the end away from the guide rod. The lever can be swung so that the male connector and the female connector are detachably connected. The other end of the lower pressure head extends into the limiting groove and squeezes the guide rod until the movable roller moves closer to the fixed roller to clamp the elastic line.

[0021] The beneficial effects of the above technical solution are: its structure is simple. After the male and female parts are connected and the pressure head is inserted into the limiting groove, the distance between the movable roller and the fixed roller can be adjusted by adjusting the length of the guide rod, that is, the deformation of the elastic line under the pressure of the movable roller and the fixed roller support can be adjusted.

[0022] The connecting component in the above technical solution includes a pin, one end of which is rotatably connected to the corresponding end of the lever, and the other end of the pin is provided with an enlarged portion, with the end of the enlarged portion near the pin serving as a hooking surface. The connecting female component includes a column and an elastic pin. The column is mounted on the beam and is parallel to the support column. The upper end of the column is recessed into a slot. The elastic pin is located at the upper end of the column. The enlarged portion on the pin extends into the slot, and the elastic pin can be moved until its pin end is located at the opening of the slot to limit the enlarged portion within the slot, or the pin end of the elastic pin can be removed from the opening of the slot to release the limitation on the enlarged portion.

[0023] The advantages of the above technical solution are that its structure is simple and the connection and disconnection of the female and male components are relatively convenient.

[0024] The adjusting component described in the above technical solution is a telescopic cylinder, which is installed on the beam rod, and its telescopic end is connected to the end of the guide rod away from the slide. The adjusting component extends and retracts to adjust the sliding of the slide relative to the mounting frame.

[0025] The advantages of the above technical solution are that it makes the system highly automated and easy to operate.

[0026] The above technical solution also includes a controller and a flexible wire monitoring sensor. The flexible wire monitoring sensor is used to monitor the conveying status of the flexible wire. Both the adjusting component and the flexible wire monitoring sensor are electrically connected to the controller.

[0027] The beneficial effect of the above technical solution is that the telescopic component's extension and retraction can be automatically adjusted according to the sensing status of the elastic line monitoring sensor, thereby making the entire equipment highly automated.

[0028] In the above technical solution, a guide ring is installed in the middle of at least one side of the mounting frame, and the middle of the gap between the movable roller and the fixed roller is aligned with the guide ring. The guide ring is used to allow the elastic wire to pass through and to limit the elastic wire.

[0029] The beneficial effect of the above technical solution is that the elastic wire can be circumferentially limited by the guide ring. Attached Figure Description

Detailed Implementation

[0045] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention. The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0046] Example 1

[0047] like Figure 1As shown, this embodiment provides an elastic wire tension and deformation limiter, including a mounting frame 1, a fixed roller 2, a slide 3, a movable roller 4, and an adjusting mechanism 5. The fixed roller 2 is rotatably mounted on the mounting frame 1; the slide 3 is slidably mounted on the mounting frame 1, and can slide to be close to or away from the fixed roller 2; the movable roller 4 is rotatably mounted on the slide 3 and is parallel to the fixed roller 2; the adjusting mechanism 5 is mounted on the mounting frame 1, and its driving end is connected to the slide 3; the elastic wire 6 passes through and is sandwiched between the fixed roller 2 and the movable roller 4 for conveying, and the adjusting mechanism 5 is used to adjust the slide 3 to move the movable roller 4 to be close to or away from the fixed roller 2. The fixed roller 2 is used to adjust the deformation and frictional resistance at the clamping point of the elastic wire 6. When a fixed tension is applied to the elastic wire, the movable roller and the fixed roller clamp the elastic wire, applying resistance to the tension. Under this tension, the elastic wire will be stretched and store energy. The degree to which the movable roller and the fixed roller clamp the elastic wire determines the magnitude of the resistance between them. The resistance to the tension of the elastic wire can be adjusted by adjusting the distance between the movable roller and the fixed roller. This allows the distance between the movable roller and the fixed roller to be adjusted according to the required specifications of the elastic wire to meet the needs of energy storage, preventing the elastic wire from breaking during energy storage and thus protecting the elastic wire during energy storage.

[0048] like Figure 1 and Figure 2 As shown, the mounting frame 1 in the above technical solution includes a beam 11 and two slide rods 12. The two slide rods 12 are parallel to each other and spaced apart. The beam 11 is arranged laterally and connected to the same end of the two slide rods 12. The fixed roller 2 and the movable roller 4 are both arranged laterally between the two slide rods 12. The two ends of the fixed roller 2 are rotatably connected to the ends of the two slide rods 12 away from the beam 11. The slide frame 3 is slidably connected to the two slide rods 12. The movable roller 4 is located between the beam 11 and the fixed roller 2, and its two ends are rotatably connected to the slide frame 3. Its structure is simple and makes the fixed roller more stable on the mounting frame. At the same time, it is more convenient to slide the movable roller on the mounting frame.

[0049] like Figures 1-3As shown, the slide 3 in the above technical solution includes a connecting rod 31 and two connecting plates 32. The two connecting plates 32 correspond one-to-one with the two slide rods 12. Each connecting plate 32 is slidably disposed on the corresponding slide rod 12 and located between the movable roller 4 and the beam rod 11. The connecting rod 31 is arranged laterally, and its two ends are connected to the ends of the two connecting plates 32 near the beam rod 11. The two ends of the movable roller 4 are rotatably connected to the other ends of the two connecting plates 32. The connecting rod 31 is connected to the drive end of the adjusting mechanism 5. Its structure is simple, and the two connecting plates can move synchronously on the mounting frame under the action of the connecting rod, so that the movable roller can always remain parallel to the fixed roller when sliding.

[0050] See details Figure 2 , Figures 5-7 In the above technical solution, each of the two slide rods 12 has a transversely penetrating, straight-strip-shaped sliding hole 121 along its length. The two connecting plates 32 are located on opposite sides of the two slide rods 12. Both ends of the connecting rod 31 pass through the two sliding holes 121 and are connected to the connecting plates 32. Both ends of the movable roller 4 pass through the sliding holes 121 and are rotatably connected to the two connecting plates 32. This simple structure allows the two sliding holes to limit and guide the movable roller and connecting rod, eliminating the need for a complex structure to achieve a sliding connection between the carriage and the mounting frame. Specifically, the slide rod can be a hollow rod, and the sliding hole can only penetrate the inner hole of the slide rod. In this case, the connecting plate can be placed inside the corresponding slide rod, making the connection between the mounting frame and the carriage more aesthetically pleasing.

[0051] like Figure 1As shown, the adjustment mechanism 5 in the above technical solution includes an adjustment member 51, a guide rod 52, and a first spring 53. One end of the guide rod 52 is perpendicularly connected to the connecting rod 31, and the other end is provided with a limit block 521. The guide rod 52 is slidably connected to the beam rod 11. The first spring 53 is sleeved on the guide rod 52, and its two ends abut against the limit block 521 and the beam rod 11, respectively. The adjustment member 51 is mounted on the mounting frame 1, and its driving end is connected to the guide rod 52. It is used to adjust the sliding of the guide rod 52 relative to the beam rod 11 to adjust the fixed roller. The distance between the fixed roller 2 and the movable roller 4 is such that the elastic force of the first spring 53 drives the guide rod 52 to move the movable roller 4 away from the fixed roller 2. Its structure is simple, so that the driving end of the adjusting member only needs to contact the end of the limiting block away from the guide rod. Only when the adjusting member overcomes the elastic force of the first spring to squeeze the guide rod to move towards the fixed roller, the distance between the fixed roller and the movable roller decreases. When the driving member of the adjusting member retracts, the guide rod drives the movable roller to move away from the fixed roller under the elastic force of the first spring, and the displacement of the movable roller is consistent with the retraction amount of the driving end of the adjusting member.

[0052] In the above technical solution, the beam rod 11 is provided with a through hole 111, and the guide rod 52 passes through the through hole 111 and slides in contact with the beam rod 11. Its structure is simple and makes it more convenient for the guide rod to slide with the beam rod.

[0053] like Figure 1 and Figure 9 As shown, in the above technical solution, the guide rod 52 is an adjustable rod. The adjusting component 51 includes a support column 511, a lever 512, a pressing head 513, a connecting male component 514, and a connecting female component 515. The support column 511 and the connecting female component 515 are both located on the side of the beam rod 11 away from the slide 3, and the through hole 111 is located between the support column 511 and the connecting female component 515. One end of the lever 512 is rotatably connected to the end of the support column 511 away from the beam rod 11. The connecting male component 514 is installed on the other end of the lever 512. One end of the pressing head 513 is rotatably connected to the middle of the lever 512. The movable connection is provided with a limiting groove 5211 at one end of the limiting block 52 away from the guide rod 52. The lever 512 can be rotated so that the male connecting part 514 and the female connecting part 515 can be detachably connected. The other end of the pressing head 513 extends into the limiting groove 5211 and presses the guide rod 52 until the movable roller 4 moves closer to the fixed roller 2 to clamp the elastic line 6. The structure is simple. After the male connecting part and the female connecting part are connected and the pressing head extends into the limiting groove, the distance between the movable roller and the fixed roller can be adjusted by adjusting the length of the guide rod (that is, adjusting the deformation of the elastic line under the pressure of the movable roller and the fixed roller support).

[0054] The connecting male component 514 in the above technical solution includes a pin 5141. One end of the pin 5141 is rotatably connected to the corresponding end of the lever 512. The other end of the pin 5141 is provided with an enlarged portion 5142, and the end of the enlarged portion 5142 near the pin 5141 is a hooking surface. The connecting female component 515 includes a column 5151 and an elastic pin 5152. The column 5151 is mounted on the beam 11 and is parallel to the support column 511. The upper end of the column 5151 is recessed with a slot 51511. The elastic pin 5152 is disposed at the upper end of the column 5151. The enlarged portion 5142 on the pin 5141 extends into the slot 51511. The elastic pin 5152 can be moved until its pin end is located at the opening of the slot 51511 to limit the enlarged portion 5142 in the slot 51511. Alternatively, the pin end of the elastic pin 5152 can be removed from the opening of the slot 51511 to release the limitation on the enlarged portion 5142. The structure is simple, and the connection and disconnection of the female and male components are relatively convenient.

[0055] Among them, such as Figures 2-4 as well as Figure 6 and Figure 7 As shown, the guide rod may further include a first rod body 522, a second rod body 523, a sleeve rod 524, and a locking bolt 525. The limiting block 521 is disposed at one end of the first rod body, the first spring is sleeved on the first rod body, the second rod body is disposed at the other end of the first rod body and is coaxially connected and fixed to the first rod body, the end of the second rod body away from the first rod body can extend into the sleeve rod, and a locking screw hole is provided on the side wall of the sleeve rod near the end of the second rod body, and the locking screw hole is connected to the sleeve rod. The inner holes are perpendicular to each other. The locking bolt is threadedly connected to the locking screw hole. The depth to which the second rod is inserted into the sleeve rod is adjustable. Tightening the locking bolt can lock the second rod relative to the sleeve rod, while loosening the locking bolt can release the second rod relative to the sleeve rod (the locking principle of the locking bolt is similar to the locking bolt on a vernier caliper). This allows for the adjustment of the guide rod's length. The first rod penetrates the through hole and slides in contact with it. The end of the sleeve rod away from the limiting block is perpendicularly connected to the slide rod.

[0056] The pressing head can be straight, and the end away from the lever can be spherical, making it easier for it to extend into the limiting groove.

[0057] The end of the enlarged portion opposite to the pin can be spherical, making it easier for it to extend into the slot.

[0058] Specifically, such as Figures 9-12 As shown, the connecting component further includes a first flange ring, a second flange ring, and multiple connectors (each connector includes a bolt and at least one nut, and may also include a washer). The first flange ring is coaxially connected to or integrally formed with the end of the column facing away from the beam. The inner hole of the first flange ring communicates with the slot (the inner hole of the first flange ring forms the slot opening). The second flange ring is connected to the first flange ring via multiple connectors (i.e., the first and second flange rings are aligned and connected by multiple bolts and nuts, which is prior art and will not be elaborated here). However, there is a gap between the second and first flange rings (and the inner hole of the second flange ring is aligned with the inner hole of the first flange ring; when the expanded portion is inserted into the slot, it must first pass through the inner hole of the second flange ring). A washer can be fitted onto each bolt between the first and second flange rings. The multiple washers have the same height, and an elastic pin is set on the second flange ring. Specifically… The elastic pin may include a push rod 51521, a second spring 51522, a slider 51523, a handle ring 51524, a connecting block 51525, and a connecting ear 51256. The connecting ear is disposed at the edge of the second flange ring or integrally formed with the second flange ring. A connecting block is disposed at the lower end of the connecting ear. The push rod passes through the connecting block and slides in contact with the connecting block (wherein, the slider is located in the gap between the first flange ring and the second flange ring). One end of the push rod faces the upper end of the slot and is connected to the slider. The handle ring is disposed at the other end of the push rod. The connecting block is located between the slider and the handle ring. The second spring is sleeved on the push rod and is located between the slider and the connecting block. The elastic force of the second spring is used to drive the slider to move towards the slot opening to limit the expansion portion. Under the action of external force, the handle ring is pulled to drive the push rod and the slider to move away from the slot and above, at which time the limitation on the expansion portion can be released. The slider can fit against the lower end of the second flange ring, so that when the slider limits the expansion, the second flange ring can hold the upper end of the slider, preventing the push rod from deforming and bending upward after long-term use. The handle ring can be circular, and the end of the push rod away from the slider can be connected to the handle ring radially (and the push rod is located outside the handle ring).

[0059] In this embodiment, the first flange ring and the second flange ring are connected by bolts, nuts and washers, so that the second flange ring can be removed from the first flange ring for maintenance when needed. The push rod can be arranged radially along the second flange ring, and the connecting block has holes through which the push rod can slide.

[0060] like Figure 1 , Figure 2 as well as Figures 6-8 As shown, in the above technical solution, a guide ring 9 is installed in the middle of at least one side of the mounting frame 1. The middle of the gap between the movable roller 4 and the fixed roller 2 is aligned with the guide ring 9. The guide ring 9 is used for the elastic line 6 to pass through and to limit the elastic line 6. In this way, the guide ring can limit the elastic line circumferentially. Preferably, guide rings can be provided on both sides of the mounting frame, and the two guide rings are aligned with each other. Each guide ring can be connected to two slide rods through four support rods. For example, each slide rod can be connected to the guide ring through two support rods. This makes the guide ring more stable on the mounting frame. One end of each support rod is connected to the edge of the guide ring, and the other end is connected to the slide rod on the corresponding side.

[0061] The principle of this embodiment is as follows: Considering the uniformity of the material of each elastic wire, when each elastic wire is stretched by external force to store energy, it can pass between the movable roller and the fixed roller, and be clamped by both (the tightness of the clamping depends on the set elongation rate of the elastic wire). The tightness of the clamping is achieved by adjusting the length of the guide rod (when the guide rod is extended, the gap between the movable roller and the fixed roller decreases, thus increasing the clamping force on the elastic wire; under the condition of a fixed traction force, the elongation rate of the elastic wire increases; when the guide rod is shortened, the gap between the movable roller and the fixed roller increases, thus decreasing the clamping force on the elastic wire; under the condition of a fixed traction force, the elongation rate of the elastic wire decreases). For a single elastic wire, it is only necessary to adjust the length of the guide rod to the correct position before energy storage.

[0062] Example 2

[0063] Same as Example 1, except that, as Figure 13 As shown, the guide rod can be a straight rod (i.e., a non-retractable rod), and the adjusting member 51 is a telescopic cylinder, which is installed on the beam rod 11, and its telescopic end is connected to the end of the guide rod 52 away from the slide 3. The adjusting member 51 extends and retracts to adjust the slide 3 relative to the mounting frame 1, thus making it highly automated and easy to operate.

[0064] The above technical solution also includes a controller 7 and an elastic line monitoring sensor 8. The elastic line monitoring sensor 8 is used to monitor the conveying status of the elastic line 6. Both the adjusting component 51 and the elastic line monitoring sensor 8 are electrically connected to the controller 7, so that the extension and retraction of the telescopic component can be automatically adjusted according to the sensing status of the elastic line monitoring sensor, thereby making the entire equipment highly automated. The controller can be an ARM series microcontroller, the telescopic cylinder can be a telescopic pneumatic cylinder or a telescopic electric cylinder, and the adjusting component is mounted on the beam rod through a support frame. The support frame can be a "Γ" shaped or "n" shaped component, which is installed on the side of the beam rod away from the slide rod. The adjusting component is mounted on the support frame, and its telescopic end is aligned with the limiting groove and extends into the limiting groove. The adjustment and telescopic movement works in conjunction with the first spring to drive the guide rod to move.

[0065] like Figure 14 As shown, after the elastic cord is stretched, the cross-sectional dimensions of the elastic cord on both sides between the movable and fixed rollers will change. The diameter of the elastic cord at the stretched end will become smaller (or the wall thickness will become thinner). Of course, its light transmittance will also increase. For elastic cords of the same specification, the degree of diameter reduction, wall thickness thinning, and light transmittance increase are all positively correlated with its stretching rate (that is, the greater the stretching, the greater the increase in light transmittance, the greater the wall thickness thinning, and the greater the diameter reduction). Since light transmittance detection is more convenient, the elastic cord monitoring sensor in this embodiment can be a light transmittance detector (LS116 light transmittance meter). In this way, the controller can adjust the extension and retraction of the adjusting component (i.e., the distance between the fixed and movable rollers) in real time according to the change in light transmittance after the elastic cord is stretched. This ensures that the light transmittance of the stretched elastic cord is in a dynamic equilibrium state, that is, the elastic cord stretching rate is stable, and the elastic cord will not break due to uneven texture. The elastic line monitoring sensor 8 is located near the fixed roller and the movable roller, which allows the adjusting member to extend and retract more nimbly.

[0066] The principle of this embodiment is as follows: If the texture of a single elastic thread is uneven, in order to prevent the weakest part of the elastic thread from breaking due to excessive deformation rate during stretching, this embodiment, under the premise of fixed traction force, uses the light transmittance of the elastic thread after being stretched as an indicator. The controller controls the adjusting component to automatically adjust the clamping tightness of the movable roller and the fixed roller on the elastic thread. This ensures that the light transmittance of the elastic thread is relatively constant at all points when it is stretched, thereby preventing the elastic thread from breaking (of course, the set threshold of light transmittance must meet the requirement that the weakest part of the elastic thread will not break when stretched to that light transmittance). When the light transmittance detector detects a decrease in the light transmittance of the elastic thread, it indicates that the elastic thread is relatively coarse. At this time, the adjusting component can extend to increase the clamping force of the movable roller and the fixed roller on the elastic thread. Conversely, if the light transmittance detector detects an increase in the light transmittance of the elastic thread, it indicates that the elastic thread is relatively fine. At this time, the adjusting component can retract to decrease the clamping force of the movable roller and the fixed roller on the elastic thread.
