Description

[0001] The present invention belongs to the technical field of monofilament heat setting, and specifically relates to a monofilament heat setting device and a heat setting method thereof. Background Art

[0002] With the continuous development of the monofilament manufacturing industry, higher requirements have been put forward for the monofilament manufacturing process and manufacturing equipment. In the existing process, after the monofilament is curled, a heat setting device is required to perform heat setting treatment on the monofilament.

[0003] For example, the utility model patent with the patent authorization announcement number: CN216998691U discloses a heat setting device for anti-aging and flame-retardant monofilaments, including a bottom plate and an extrusion unit; a collection unit and a heat setting box are arranged on the upper surface of the bottom plate, a feed port and a discharge port are respectively arranged on both sides of the heat setting box, an electric heating tube is arranged in the heat setting box, a heat setting roller is rotatably connected in the heat setting box, and the input end of the electric heating tube is electrically connected to the output end of an external control switch group; the extrusion unit includes a support plate, a chute and a power assembly, the support plate and the chute are arranged on the heat setting box, a power assembly is arranged on the support plate, and the power assembly is connected to a rotating shaft. This device can treat the oil on the heat-set monofilament to avoid waste and pollution, and can recycle the volatilized oil to reduce waste.

[0004] Based on the retrieval of the above patent authorization announcement number and combined with the deficiencies found therein:

[0005] Existing heat setting equipment all realizes heat setting treatment by pulling the monofilament into a constant-temperature grease. However, such a setting, although ensuring that the monofilament can be heat-set at a constant temperature, the monofilament adheres to the grease, and a degreasing device needs to be set up later to specifically remove the grease attached to the monofilament. Such a setting not only increases the cost of designing the device, but also increases the steps of the entire heat setting process, reducing the speed and efficiency of heat setting the monofilament. Summary of the Invention

[0006] To solve the problem that existing heat setting equipment all realizes heat setting treatment by pulling the monofilament into a constant-temperature grease. However, such a setting, although ensuring that the monofilament can be heat-set at a constant temperature, the monofilament adheres to the grease, and a degreasing device needs to be set up later to specifically remove the grease attached to the monofilament. Such a setting not only increases the cost of designing the device, but also increases the steps of the entire heat setting process, reducing the speed and efficiency of heat setting the monofilament, the present invention provides a monofilament heat setting device and a heat setting method thereof.

[0007] The object of the present invention can be achieved by the following technical solutions:

[0008] A monofilament heat setting device, comprising a constant temperature box and a constant temperature component. A heat setting slot hole is penetrated and opened in the constant temperature box. The constant temperature component includes a constant temperature housing, a constant temperature unit and a connection unit. The constant temperature housing is arranged in the heat setting slot hole. The constant temperature unit includes a constant temperature pump, a constant temperature tank filled with constant temperature oil and a heating module. The constant temperature pump and the constant temperature tank are connected to each other and arranged in the constant temperature box. The heating module is arranged in the constant temperature tank for heating the constant temperature oil. The connection unit includes an input pipe and an output pipe. Two ends of the input pipe are respectively connected to the constant temperature pump and one end of the constant temperature housing. Two ends of the output pipe are respectively connected to the top of the constant temperature tank and the other end of the constant temperature housing.

[0009] As a preferred technical solution of the present invention, the connection unit further includes a check valve and a pressure relief valve. The input pipe is vertically arranged on one side of the end face of the constant temperature housing away from the middle of the heat setting slot hole. The check valve is hermetically arranged at the connection between the input pipe and the constant temperature housing. The output pipe is arranged on the other side of the end face of the constant temperature housing away from the middle of the heat setting slot hole. The pressure relief valve is hermetically arranged at the connection between the output pipe and the constant temperature housing.

[0010] As a preferred technical solution of the present invention, there are two groups of the constant temperature housing and the connection unit. The other constant temperature housing is arranged on the top of the heat setting slot hole. The connection relationship between the other connection unit and the other constant temperature housing is the same as the connection relationship between the connection unit and the constant temperature housing.

[0011] As a preferred technical solution of the present invention, the flow direction of the constant temperature oil in the constant temperature housing is consistent with the moving direction of the monofilament.

[0012] As a preferred technical solution of the present invention, the constant temperature component further includes two groups of sliding units. The sliding unit includes a hollow sliding block, a connecting pipe and a return pipe. The two sliding blocks are respectively arranged on both sides in the heat setting slot hole. The sliding block is arranged between the two constant temperature housings. Two ends of the connecting pipe are respectively connected to one end of the sliding block and the constant temperature pump. Two ends of the return pipe are respectively connected to the other end of the sliding block and the top of the constant temperature tank.

[0013] As a preferred technical solution of the present invention, the sliding unit further includes a rotating rod and a rotating disc. Rotating holes symmetrically arranged are respectively opened on both sides of the constant temperature box. The two rotating holes respectively correspond to and match the two sliding units one by one. Any one of the rotating rods is rotatably arranged in the corresponding rotating hole. The rotating disc is coaxially connected to the end of the rotating rod extending out of the constant temperature box. The end of the rotating rod extending into the constant temperature box is connected to the sliding block.

[0014] As a preferred technical solution of the present invention, the constant temperature assembly further includes two limiting units. Two limiting chutes are symmetrically formed at one end surface of the constant temperature housing close to the heat setting slot hole. The limiting chutes are respectively communicated with the heat setting slot hole and the interior of the constant temperature housing. The two limiting chutes are in one-to-one correspondence and matching with the two limiting units. Any one of the limiting units is slidably arranged on the corresponding limiting chute. The limiting unit includes a limiting block and a connecting block. The limiting block is slidably arranged in the constant temperature housing along the axial direction of the limiting chute. The cross-sectional shape of the limiting block is the same as the cross-sectional shape inside the constant temperature housing. The connecting block is slidably arranged in the limiting chute. Two ends of the connecting block are respectively connected with the limiting block and the sliding block.

[0015] As a preferred technical solution of the present invention, the limiting unit further includes a sealing ring. A sealing slot hole is formed in the limiting block. The sealing slot hole is arranged around the side wall of the limiting block with the central axis of the limiting block as the center. The sealing ring is arranged in the sealing slot hole. The height of the cross-sectional shape of the sealing ring is greater than the height of the cross-sectional shape of the sealing slot hole.

[0016] As a preferred technical solution of the present invention, the limiting unit further includes a communicating block. The constant temperature housing is further provided with a communicating slot hole. The communicating slot hole is communicated with the limiting chute. The communicating block is slidably arranged in the communicating slot hole. One end of the communicating block is connected with the connecting block. The width of the connecting block and the width of the communicating block are equal to the width of the limiting chute. The height of the communicating slot hole is equal to the thickness of the communicating block.

[0017] A monofilament heat setting method includes the following steps:

[0018] S1: The heating module starts to work to heat the constant temperature oil in the constant temperature tank.

[0019] S2: After the temperature of the constant temperature oil reaches a specific temperature, the constant temperature pump starts to work to pump the constant temperature oil in the constant temperature tank into the constant temperature housing.

[0020] S3: After the constant temperature oil is pumped into the constant temperature housing, the heat of the constant temperature oil will be transferred to the inside of the constant temperature housing to increase the temperature of the constant temperature housing.

[0021] S4: As the amount of the constant temperature oil pumped into the constant temperature housing increases, the excess constant temperature oil in the constant temperature housing will flow back to the constant temperature tank through the output pipe.

[0022] S5: Repeat the steps of S1 - S4 in such a cycle until the temperature of the constant temperature housing reaches a specific temperature, and then the constant temperature assembly continues to work to maintain the temperature of the constant temperature housing.

[0023] S6: The constant-temperature housing transfers heat into the heat setting slot hole, increasing the temperature of the heat setting slot hole.

[0024] S7: After the temperature of the heat setting slot hole rises to a specific temperature, the single filament passes through the heat setting slot hole, achieving the heat setting process of the single filament.

[0025] The beneficial effects of the present invention are as follows:

[0026] By providing a constant-temperature unit, the function of the constant-temperature unit is to increase the temperature of the constant-temperature housing and keep it constant at a specific temperature. After the temperature inside the constant-temperature housing rises to the designated temperature, the constant-temperature unit will maintain the temperature of the constant-temperature housing without further change. Since there is a temperature difference between the temperature in the heat setting slot hole and the temperature of the constant-temperature housing, the constant-temperature housing will transfer heat into the heat setting slot hole until the temperature in the heat setting slot hole also reaches the designated temperature. Then, the single filament will move from one end of the heat setting slot hole to the other end, and the heat in the heat setting slot hole will be transferred to the single filament, achieving the heat setting process of the single filament. Compared with the existing method of soaking the single filament in constant-temperature grease to achieve the heat setting process of the single filament, after the heat setting process of the single filament is achieved in this solution, since there is no grease attached to the single filament, the single filament after the heat setting process can directly undergo the next process without the need to remove the grease on the single filament, solving the problem that existing heat setting equipment all pulls the single filament into constant-temperature grease to achieve the heat setting process. However, with such a setting, although it ensures that the single filament can be heat-set at a constant temperature, the single filament adheres to grease, and subsequent degreasing devices need to be set up to specifically remove the grease attached to the single filament. Such a setting not only increases the cost of designing the device but also increases the entire heat setting process steps, reducing the speed and efficiency of heat setting the single filament.

Specific embodiments

[0037] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features, and their effects of the present invention as follows.

[0038] Please refer to Figures 1-7, this embodiment provides a single - filament heat - setting device, which includes a constant - temperature box 1 and a constant - temperature component. A heat - setting slot hole 101 is penetrated through the constant - temperature box 1. The constant - temperature component includes a constant - temperature housing 2, a constant - temperature unit 3, and a connection unit 4. The constant - temperature housing 2 is arranged in the heat - setting slot hole 101. The constant - temperature unit 3 includes a constant - temperature pump 301, a constant - temperature tank 302 filled with constant - temperature oil, and a heating module. The constant - temperature pump 301 and the constant - temperature tank 302 are connected to each other and arranged in the constant - temperature box 1. The heating module is arranged in the constant - temperature tank 302 and is used to heat the constant - temperature oil. The connection unit 4 includes an input pipe 401 and an output pipe 402. Two ends of the input pipe 401 are respectively connected to the constant - temperature pump 301 and one end of the constant - temperature housing 2. Two ends of the output pipe 402 are respectively connected to the top of the constant - temperature tank 302 and the other end of the constant - temperature housing 2. By setting the constant - temperature unit 3, the function of the constant - temperature unit 3 is to increase the temperature of the constant - temperature housing 2 and keep it constant at a specific temperature. After the temperature in the constant - temperature housing 2 rises to the specified temperature, the constant - temperature unit 3 will keep the temperature of the constant - temperature housing 2 unchanged. And there is a temperature difference between the temperature in the heat - setting slot hole 101 and the temperature of the constant - temperature housing 2. Therefore, the constant - temperature housing 2 will transfer heat to the heat - setting slot hole 101 until the temperature in the heat - setting slot hole 101 also reaches the specified temperature. Then the single - filament will move from one end of the heat - setting slot hole 101 to the other end, and the heat in the heat - setting slot hole 101 will be transferred to the single - filament to realize the heat - setting treatment of the single - filament. Compared with the existing method of soaking the single - filament in constant - temperature grease to realize the heat - setting treatment of the single - filament, after the heat - setting treatment of the single - filament is realized in this solution, since there is no grease attached to the single - filament, the single - filament after the heat - setting treatment can directly enter the next process without having to remove the grease on the single - filament, solving the problem that existing heat - setting equipment pulls the single - filament into constant - temperature grease to realize the heat - setting treatment. However, with such a setting, although it ensures that the single - filament can be heat - set at a constant temperature, the single - filament adheres to grease, and a degreasing device needs to be set up later to specifically remove the grease attached to the single - filament. Such a setting not only increases the cost of designing the device, but also increases the steps of the entire heat - setting process, reducing the speed and efficiency of heat - setting the single - filament.

[0039] Specifically, the thermostatic unit 3 of the present scheme heats the thermostatic shell 2 in the following manner: first, the heating module heats the thermostatic oil in the thermostatic tank 302 until the thermostatic oil is heated to a specific temperature, and then the thermostatic pump 301 starts to work. The thermostatic pump 301 will pump the thermostatic oil in the thermostatic tank 302 into the thermostatic shell 2 through the inlet pipe 401, and the thermostatic oil with high heat will transfer the heat to the thermostatic shell 2 with low heat, so as to increase the temperature of the thermostatic shell 2. Then, the thermostatic oil in the thermostatic shell 2 will flow back into the thermostatic tank 302 through the outlet pipe 402, and the heating module will continue to heat the thermostatic oil in the thermostatic tank 302. Through such a reciprocating cycle, the heating treatment of the thermostatic shell 2 is realized until the temperature of the thermostatic shell 2 rises to a specific temperature. It should also be noted that after the temperature of the thermostatic shell 2 rises to a specific temperature, the thermostatic unit 3 continues to work to always keep the temperature of the thermostatic shell 2 within the specific temperature.

[0040] In this scheme, the thermostatic oil flows in the thermostatic shell 2, so that the thermostatic oil can heat various places in the thermostatic shell 2, and the temperature of various places in the thermostatic shell 2 is kept consistent; and the thermostatic shell 2 is filled with thermostatic oil, which is then heated by the heating module, so that the temperature of the thermostatic shell 2 rises and is maintained at a specific temperature. Since the heating module needs to heat the thermostatic oil to a specific height, the actual working temperature of the heating module is higher than the temperature of the thermostatic oil. In addition, the thermostatic oil located in the thermostatic shell 2 does not flow, so the temperature of the local part of the thermostatic shell 2 close to the heating module will be higher than the rest of the thermostatic shell 2, and thus it cannot be guaranteed that after the thermostatic shell 2 transfers heat to the heat setting slot 101, the temperature in the heat setting slot 101 will be consistent everywhere. Therefore, the above scheme cannot replace the structure of the thermostatic unit 3 of this scheme.

[0041] In addition, the hot air heated to a specific temperature is continuously blown into the constant temperature shell 2 to achieve a temperature increase of the constant temperature shell 2 and maintain it at a specific temperature. When the temperature of the constant temperature shell 2 changes, the local structure of the constant temperature shell 2 will expand and contract due to heat, making it impossible to ensure that the inner wall of the constant temperature shell 2 is flat everywhere, and local depressions will occur. When the hot air blows through the inner wall of the constant temperature shell 2, the local depressions will occur on the inner wall of the constant temperature shell 2, which will also cause the temperature of each part of the constant temperature shell 2 to be inconsistent everywhere. Therefore, the above scheme cannot replace the structure of the constant temperature unit 3 of this scheme.

[0042] Specifically, to ensure the normal operation of the device, the connection unit 4 of this solution further includes a one-way valve 403 and a pressure relief valve 404. The input pipe 401 is vertically arranged on one side of the end face of the constant temperature housing 2 away from the middle of the heat setting slot hole 101. The one-way valve 403 is hermetically arranged at the connection between the input pipe 401 and the constant temperature housing 2. The output pipe 402 is arranged on the other side of the end face of the constant temperature housing 2 away from the middle of the heat setting slot hole 101. The pressure relief valve 404 is hermetically arranged at the connection between the output pipe 402 and the constant temperature housing 2. By setting the one-way valve 403, it can ensure that the flow direction of the constant temperature oil will not reverse, that is, the constant temperature oil flows from the constant temperature tank 302 into the constant temperature housing 2 through the input pipe 401, and then flows back into the constant temperature tank 302 from the constant temperature housing 2 through the output pipe 402. In addition, it is also worth noting that since the constant temperature housing 2 is arranged at the bottom inside the heat setting slot hole 101 and the length of the constant temperature housing 2 is equal to the depth of the heat setting slot hole 101. Therefore, in fact, the heat of the constant temperature housing 2 is transferred to the inside of the heat setting slot hole 101 through the end face of the constant temperature housing 2 close to the middle of the heat setting slot hole 101. In order to quickly realize the heating treatment of the heat setting slot hole 101 by the constant temperature housing 2, it is necessary to ensure that the end face of the constant temperature housing 2 close to the middle of the heat setting slot hole 101 can be replenished with heat in time. Therefore, the input pipe 401 of this solution is vertically arranged on one side of the end face of the constant temperature housing 2 away from the middle of the heat setting slot hole 101. When the constant temperature oil in the constant temperature tank 302 flows through the input pipe 401 into the constant temperature housing 2, due to the inertia of the flow of the constant temperature oil, the constant temperature oil flowing into the constant temperature housing 2 will directly flow and adhere to the end face of the constant temperature housing 2 close to the middle of the heat setting slot hole 101 before falling towards the bottom inside the constant temperature housing 2 due to the action of gravity. And, since the working power of the constant temperature pump 301 in this solution is large enough, even after the constant temperature housing 2 is filled with constant temperature oil, the constant temperature oil flowing into the constant temperature housing 2 through the input pipe 401 will also directly flow and adhere to the end face of the constant temperature housing 2 close to the middle of the heat setting slot hole 101 due to inertia. At this time, since the constant temperature housing 2 is filled with constant temperature oil, the constant temperature oil flowing into the constant temperature housing 2 through the input pipe 401 will directly adhere to the end face of the constant temperature housing 2 close to the middle of the heat setting slot hole 101, ensuring that the heat on the constant temperature oil can always be transferred to the end face of the constant temperature housing 2 close to the middle of the heat setting slot hole 101 in time. In addition, it also needs to be noted that the output pipe 402 of this solution is arranged on the other side of the end face of the constant temperature housing 2 away from the middle of the heat setting slot hole 101, and the pressure relief valve 404 is hermetically arranged at the connection between the output pipe 402 and the constant temperature housing 2. Through such a setting, when the constant temperature housing 2 is filled with constant temperature oil and there is more constant temperature oil entering the constant temperature housing 2, the excess constant temperature oil will flow back into the constant temperature tank 302 through the output pipe 402.

[0043] It should be noted that the output pipe 402 of this solution is interconnected with the top of the constant temperature tank 302, while the constant temperature pump 301 is interconnected with the bottom of the constant temperature tank 302, and the heating module is arranged at the bottom of the constant temperature pipe. Through such an arrangement, the constant temperature oil that is first heated at the bottom of the constant temperature pipe can be pumped into the constant temperature housing 2, and the constant temperature oil that flows back to the top of the constant temperature tank 302 is reheated.

[0044] According to the description of the above embodiments, in order to further improve the speed and efficiency of heating the heat setting slot hole 101 of this solution, two groups of constant temperature housings 2 and connection units 4 are provided in this solution. Another constant temperature housing 2 is arranged on the top of the heat setting slot hole 101, and the connection relationship between another connection unit 4 and another constant temperature housing 2 is the same as the connection relationship between the connection unit 4 and the constant temperature housing 2; specifically, both ends of the input pipe 401 of another connection unit 4 are respectively interconnected with the constant temperature pump 301 and another constant temperature housing 2, and another input pipe 401 is vertically arranged on one side of the end face of another constant temperature housing 2 away from the middle of the heat setting slot hole 101. Another one-way valve 403 is hermetically arranged at the connection between another input pipe 401 and another constant temperature housing 2. Another output pipe 402 is arranged on the other side of the end face of another constant temperature housing 2 away from the middle of the heat setting slot hole 101, and another pressure relief valve 404 is hermetically arranged at the connection between another output pipe 402 and another constant temperature housing 2.

[0045] According to the description of the above embodiments, it can be known that when the monofilament of this solution is subjected to heat setting treatment, it will move from one end of the heat setting slot hole 101 to the other end. During the movement of the monofilament in the heat setting slot hole 101, the monofilament will continuously absorb the heat in the heat setting slot hole 101 to increase the temperature of the monofilament, so as to achieve the effect of heat setting the monofilament; therefore, when the monofilament just enters the heat setting slot hole 101, the speed at which the monofilament absorbs heat reaches the fastest, and as the temperature of the monofilament increases, the speed at which the monofilament absorbs heat will continuously slow down. Based on this, when the monofilament is subjected to heat setting treatment in the heat setting slot hole 101, along the moving direction of the monofilament, the speed at which the front end of the heat setting slot hole 101 consumes heat will be greater than the speed at which the rear end of the heat setting slot hole 101 consumes heat. In order to timely supplement the heat consumed by the front end of the heat setting slot hole 101, the flow direction of the constant temperature oil in the constant temperature housing 2 of this solution is the same as the moving direction of the monofilament. Since the heat of the constant temperature oil will be transferred to the end face of the constant temperature housing 2 close to the middle of the heat setting slot hole 101 when the constant temperature oil just enters the constant temperature housing 2, especially when the constant temperature housing 2 is filled with the constant temperature oil in the constant temperature housing 2, the constant temperature oil flowing from the input pipe 401 into the constant temperature housing 2 will, under the inertial force of the constant temperature pump 301 on the constant temperature oil, pump the constant temperature oil to one end of the constant temperature housing 2 close to the heat setting slot hole 101, so that the heat of the constant temperature oil is directly transferred to the end face of the constant temperature housing 2 close to the heat setting slot hole 101, and can quickly supplement the heat for the front end of the heat setting slot hole 101.

[0046] In order to further improve the heating speed and efficiency of the heat setting slot hole 101 in this solution, the constant temperature component of this solution further includes two sliding units 5. The sliding unit 5 includes a hollow sliding block 501, a connecting pipe 502 and a return pipe 503. The two sliding blocks 501 are respectively arranged on both sides inside the heat setting slot hole 101. The sliding block 501 is arranged between the two constant temperature shells 2. The two ends of the connecting pipe 502 are respectively connected to one end of the sliding block 501 and the constant temperature pump 301, and the two ends of the return pipe 503 are respectively connected to the other end of the sliding block 501 and the top of the constant temperature tank 302. By providing two sliding blocks 501 and conveying constant temperature oil into the sliding block 501, the sliding block 501 is raised and maintained at a specific temperature, so that the sliding block 501 transfers heat to the heat setting slot hole 101, further improving the heating speed and efficiency of the heat setting slot hole 101 in this solution. It should be noted that the flow direction of the constant temperature oil in the sliding block 501 is consistent with the moving direction of the monofilament, better supplementing heat to the front end of the heat setting slot hole 101, and the two sliding blocks 501 and the two constant temperature shells 2 are jointly arranged around the heat setting slot hole 101 to jointly transfer heat into the heat setting slot hole 101.

[0047] During the process of the device performing heat setting treatment on the monofilament, since the diameters of different types of monofilaments do not differ much, in fact, the distance between the two constant temperature shells 2 does not need to be changed; when the device performs heat setting treatment on the monofilament, in order to accelerate the speed and efficiency of the heat setting treatment on the monofilament, usually multiple monofilaments are heat set together, but the number of monofilaments often needs to be determined according to the actual production quantity. Therefore, the number of monofilaments heat set together at the same time is uncertain. Based on this, this solution needs to adjust the distance between the two sliding blocks 501 according to the number of monofilaments undergoing heat setting treatment to ensure the speed and efficiency of the heat transfer of the device to the heat setting slot hole 101. The sliding unit 5 further includes a rotating rod 504 and a rotating disk 505. Symmetrically arranged rotating holes are respectively opened on both sides of the constant temperature box 1. The two rotating holes are respectively in one-to-one correspondence and matching with the two sliding units 5. Any rotating rod 504 is rotatably arranged on the corresponding rotating hole. The rotating disk 505 is coaxially connected to the end of the rotating rod 504 extending outside the constant temperature box 1. The end of the rotating rod 504 extending into the constant temperature box 1 is connected to the sliding block 501. By driving the rotating disk 505 to rotate, the rotating rod 504 is telescoped and slid in the rotating hole, and then the sliding block 501 connected to the rotating rod 504 is controlled to slide in the heat setting slot hole 101. Since the axial direction of the rotating rod 504 is perpendicular to the axial direction of the heat setting slot hole 101, the sliding of the two sliding blocks 501 can change the distance between the two sliding blocks 501, and then change the width of the monofilament extending into the heat setting slot hole 101.

[0048] According to the description of the above embodiments, when the two sliding blocks 501 slide and the distance between the two sliding blocks 501 is reduced, if the width within the constant temperature housing 2 does not change along with the change in the distance between the two sliding blocks 501, then in fact, the part of the constant temperature housing 2 beyond the distance between the two sliding blocks 501 cannot perform heat setting on the monofilament, resulting in waste of heat. Based on this, in order to further improve the heat transfer speed and efficiency of the device to the heat setting slot 101, when the distance between the two sliding blocks 501 changes, the width of the constant temperature oil flowing within the constant temperature housing 2 should also change correspondingly; specifically, the constant temperature component of this solution further includes two limiting units 6. Two limiting chutes 201 are symmetrically opened on one end face of the constant temperature housing 2 close to the heat setting slot 101. The limiting chutes 201 are respectively communicated with the heat setting slot 101 and the interior of the constant temperature housing 2. The two limiting chutes 201 are in one-to-one correspondence and matching with the two limiting units 6. Any one of the limiting units 6 is slidably arranged on the corresponding limiting chute 201, and the central axis direction of the limiting chute 201 is the same as the sliding direction of the sliding block 501. The limiting unit 6 includes a limiting block 601 and a connecting block 602. The limiting block 601 is slidably arranged within the constant temperature housing 2 along the axial direction of the limiting chute 201. The cross-sectional shape of the limiting block 601 is the same as the cross-sectional shape within the constant temperature housing 2. The two limiting blocks 601 and the side walls within the constant temperature housing 2 together form a flow space. The input pipe 401 and the output pipe 402 are respectively communicated with the flow space. The two limiting blocks 601 are in one-to-one correspondence and matching with the two sliding blocks 501. The end face of any one of the limiting blocks 601 communicating with the flow space and the end face of the corresponding sliding block 501 close to the other sliding block 501 are on the same vertical plane. The connecting block 602 is slidably arranged within the limiting chute 201. The two ends of the connecting block 602 are respectively connected to the limiting block 601 and the sliding block 501; by providing the limiting block 601 and the connecting block 602, when the sliding block 501 slides, the sliding block 501 will drive the limiting block 601 to move together through the connecting block 602, so that the distance between the two sliding blocks 501 is always equal to the bottom width within the flow space, thereby further improving the heat transfer speed and efficiency of the device to the heat setting slot 101.

[0049] In addition, to ensure that the constant-temperature oil in the flow space does not flow to the remaining positions within the constant-temperature housing 2, the limiting unit 6 of this solution further includes a sealing ring 603. The limiting block 601 is provided with a sealing groove hole. The sealing groove hole is arranged around the side wall of the limiting block 601 with the central axis of the limiting block 601 as the center. The sealing ring 603 is arranged in the sealing groove hole. The cross-sectional shape height of the sealing ring 603 is greater than the cross-sectional shape height of the sealing groove hole. By providing the sealing ring 603, since the cross-sectional shape height of the sealing ring 603 is greater than the cross-sectional shape height of the sealing groove hole, and the sealing ring 603 has an elastic structural characteristic, it will always fill and fit the gap between the limiting block 601 and the inner side wall of the constant-temperature housing 2, restricting the constant-temperature oil in the flow space from flowing to the remaining positions within the constant-temperature housing 2. It is worth noting that the sealing ring 603 of this solution has the characteristic of high temperature resistance.

[0050] In addition, it should also be noted that to further restrict the constant-temperature oil in the flow space from flowing into the heat setting groove hole 101 through the limiting sliding groove 201, the limiting unit 6 of this solution further includes a connecting block 604. The constant-temperature housing 2 is further provided with a connecting groove hole 202. The connecting groove hole 202 is interconnected with the limiting sliding groove 201. The connecting block 604 is slidably arranged in the connecting groove hole 202. One end of the connecting block 604 is connected to the connecting block 602. The width of the connecting block 602 and the width of the connecting block 604 are equal to the width of the limiting sliding groove 201. The height of the connecting groove hole 202 is equal to the thickness of the connecting block 604. By providing the connecting block 604, since the width of the connecting block 604 is equal to the width of the limiting sliding groove 201, the two side end faces of the connecting block 604 are arranged in mutual contact with the two side end faces of the limiting sliding groove 201, realizing the sealing of the limiting sliding groove 201 located in the flow space by the connecting block 604, so that the constant-temperature oil in the flow space cannot flow into the heat setting groove hole 101 through the limiting sliding groove 201 located in the flow space. It is also worth noting that since the height of the connecting groove hole 202 of this solution is equal to the thickness of the connecting block 604, and the width of the connecting groove hole 202 is equal to the width of the connecting block 604, such a setting makes the connecting block 604 arranged in mutual contact with the inner side wall of the connecting groove hole 202, so that the constant-temperature oil in the flow space cannot flow into the heat setting groove hole 101 through the connecting groove hole 202.

[0051] Furthermore, the limiting unit 6 of this solution further includes two limiting rings 605. The connecting block 604 and the connecting piece 602 together form two limiting slots. The two limiting slots are respectively arranged on the end side walls of the connecting block 604 and the connecting piece 602. The formation of the limiting slots is in an "L" shape. The top end face of the limiting slot is arranged in mutual fit with the bottom face of the limiting block 601. The bottom end face of the limiting slot is always located within the connecting slot 202. The two limiting slots are in one-to-one correspondence and match with the two limiting rings 605. Any one of the limiting rings 605 is arranged in the corresponding limiting slot. The cross-sectional shape height of the limiting ring 605 is greater than the cross-sectional shape height of the limiting slot. By setting the limiting ring 605, since the cross-sectional shape height of the limiting ring 605 is greater than the cross-sectional shape height of the limiting slot, and the limiting ring 605 has an elastic structural characteristic, it will always fill and fit in the gap between the side wall formed by the connecting block 604 and the connecting piece 602 and the limiting chute 201. The constant-temperature oil in the limiting flow space cannot flow through the gap between the side wall formed by the connecting block 604 and the connecting piece 602 and the limiting chute 201 into the heat setting slot 101. It is worth noting that the limiting ring 605 of this solution has the characteristic of being heat-resistant.

[0052] Furthermore, the limiting unit 6 of this solution further includes a blocking ring 606. The connecting block 604 is provided with an annular blocking slot at one end of the connecting slot 202. The blocking slot is in mutual communication with the bottom end face of the limiting slot. The blocking ring 606 is arranged in the blocking slot, and the cross-sectional shape height of the blocking ring 606 is greater than the cross-sectional shape height of the blocking slot. By setting the blocking ring 606, since the cross-sectional shape height of the blocking ring 606 is greater than the cross-sectional shape height of the blocking slot, and the blocking ring 606 has an elastic structural characteristic, it will always fill and fit in the gap between the connecting block 604 and the connecting slot 202. The constant-temperature oil in the limiting flow space cannot flow through the gap between the connecting block 604 and the connecting slot 202 into the heat setting slot 101. It is worth noting that the blocking ring 606 of this solution has the characteristic of being heat-resistant.

[0053] According to the description of the above embodiments, since the distance between the two sliding blocks 501 in this solution will change, when the distance between the two sliding blocks 501 becomes smaller, it will cause the constant-temperature oil pressure in the flow space to increase instantaneously, so that the constant-temperature oil in the flow space will press the sealing ring 603 to deform, resulting in the constant-temperature oil in the flow space spilling out of the flow space; based on this, this solution further includes a pressure-changing component 7, which includes a pressure-changing oil 701, a pressure-changing spring 702 and a pressure-changing block 703. The limiting block 601 is provided with a pressure-changing groove hole, which is communicated with the sealing groove hole, and the distance between the pressure-changing groove hole and the central axis of the limiting block 601 is smaller than the distance between the sealing groove hole and the central axis of the limiting block 601. A pressure-changing space is jointly formed between the sealing ring 603 and the limiting block 601, and the pressure-changing oil 701 is arranged in the pressure-changing space; the limiting block 601 is also provided with a sliding groove hole, which is respectively communicated with the pressure-changing space and the flow space. The pressure-changing block 703 is slidably and sealingly arranged in the sliding groove hole, the pressure-changing spring 702 is arranged in the pressure-changing space, and the two ends of the pressure-changing spring 702 are respectively connected with the limiting block 601 and the pressure-changing block 703. By providing the pressure-changing component 7, when the distance between the two sliding blocks 501 changes, the distance between the corresponding two limiting blocks 601 will also change. When the distance between the two limiting blocks 601 becomes smaller, it will cause the force exerted by the flow space on the limiting block 601 to increase instantaneously. Furthermore, the constant-temperature oil in the flow space will press the pressure-changing block 703, causing the pressure-changing block 703 to move towards the inside of the pressure-changing space, thereby making the volume of the pressure-changing space smaller. Since the volume of the pressure-changing oil 701 in the pressure-changing space remains unchanged, therefore, the oil pressure of the pressure-changing oil 701 increases, and then the pressure-changing oil 701 will press the sealing ring 603, making the fitting force between the sealing ring 603 and the inner wall of the constant-temperature housing 2 increase, avoiding the situation that the constant-temperature oil with increased oil pressure in the flow space presses the sealing ring 603, causing the sealing ring 603 to deform, and then resulting in the constant-temperature oil in the flow space spilling out of the flow space.

[0054] In addition, it is also worth noting that the transformer oil 701 in this solution is in a non-flowing state. As the heating time of the restriction block 601 increases, the temperature of the transformer oil 701 will continuously rise, causing the transformer oil 701 to expand, thus pressing the sealing ring 603 and further strengthening the acting force of the sealing ring 603 fitting with the inner wall of the constant-temperature housing 2. However, after the sealing ring 603 is pressed by the transformer oil 701 with increased oil pressure, the transformer oil 701 located in the transformation space may overflow outside the transformation space. Based on this, to solve this problem, along the direction close to the center of the restriction block 601, the opening width of the sealing groove hole in this solution gradually increases, while the cross-sectional shape of the sealing ring 603 is rectangular and its cross-sectional width does not change. Through such a setting, when the sealing ring 603 deforms, the deformed part of the sealing ring 603 will firmly adhere to the end face of the sealing groove hole, preventing the transformer oil 701 located in the transformation space from overflowing outside the transformation space.

[0055] A single-filament heat setting method includes the following steps:

[0056] S1: The heating module starts to work to heat the constant-temperature oil in the constant-temperature tank 302.

[0057] S2: After the temperature of the constant-temperature oil reaches a specific temperature, the constant-temperature pump 301 starts to work to pump the constant-temperature oil in the constant-temperature tank 302 into the constant-temperature housing 2.

[0058] S3: After the constant-temperature oil is pumped into the constant-temperature housing 2, the heat of the constant-temperature oil will be transferred to the inside of the constant-temperature housing 2 to increase the temperature of the constant-temperature housing 2.

[0059] S4: As more and more constant-temperature oil is pumped into the constant-temperature housing 2, the excess constant-temperature oil located in the constant-temperature housing 2 will flow back into the constant-temperature tank 302 through the output pipe 402.

[0060] S5: Repeat the steps of S1 - S4 in such a cycle until the temperature of the constant-temperature housing 2 reaches a specific temperature, and then the constant-temperature component continues to work to maintain the temperature of the constant-temperature housing 2.

[0061] S6: The constant-temperature housing 2 transfers heat to the heat setting groove hole 101 to increase the temperature of the heat setting groove hole 101.

[0062] S7: After the temperature of the heat setting groove hole 101 rises to a specific temperature, the single filament passes through the heat setting groove hole 101 to perform the heat setting treatment on the single filament.
