Description

Technical Field

[0001] The present invention relates to the technical field of textile machinery, and specifically to an antistatic heating device for the rubber rollers of a drawing frame. Background Art

[0002] A drawing frame, also known as a doubling frame, is a key device used in the spinning process. It combines multiple slivers, and through roller drafting, the fibers are further straightened, paralleled, and evenly mixed. At the same time, the thickness of the sliver is adjusted to improve the internal structure and evenness of the sliver, enhance the straightness and parallelism of the fibers, and provide semi-finished slivers with better quality and state for subsequent spinning processes, ensuring the quality and performance of the spun yarn.

[0003] Several rubber rollers are usually equipped on a drawing frame. The rubber roller is an important drafting component, which cooperates with the roller to form a holding nip. During the operation of the drawing frame, it effectively holds and conveys the sliver through the elastic friction force on the surface, uses elastic deformation and the roller to jointly draft the sliver, makes the fibers straighten, parallel, and evenly distributed, and can also avoid the sliver from winding through good elasticity and surface characteristics, ensuring the normal operation of the sliver and ensuring the stable quality and good evenness of the sliver produced by the drawing frame. The two ends of the roller shaft of the rubber roller are usually installed using bearing seats. When the rubber roller rotates at high speed, the shaft end and the shaft sleeve will heat severely. The long-term accumulation of heat will accelerate the damage of the rubber roller, thereby reducing its service life. Summary of the Invention

[0004] The purpose of the present invention is to provide an antistatic heating device for the rubber rollers of a drawing frame that can transfer and utilize heat to solve the technical problems proposed in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions.

[0006] The antistatic heating device for the rubber rollers of a drawing frame includes a drainage cover, an annular seat, and turbine blades. Two drainage covers are symmetrically and fixedly sleeved on the roller shaft. The two drainage covers respectively abut against the two side ends of the roller body sleeved on the roller shaft. Annular seats are fixedly sleeved on the roller shaft within the cavities of the two drainage covers. A number of turbine blades are fixedly arranged in a circumferential array on the outer peripheral walls of the two annular seats. The turbine blades on the two side annular seats are symmetrically arranged. The cross-section of the turbine blade is arc-shaped and extends outside the drainage cover. A number of through air blowing openings are arranged in a circumferential array around the roller shaft on the mutually adjacent side surfaces of the two drainage covers.

[0007] By installing a drainage cover and turbine blades on the roller shaft, two opposite transverse airflows are formed. Combining with the rubber sleeve arranged on the outer wall of the roller body, the two airflows combine to form an airflow flowing towards the periphery of the rubber roller, which can carry away the heat and blow away the dirt attached to the roller shaft, realizing effective heat dissipation and cleaning of the roller shaft.

[0008] Preferably, a rubber sleeve is fixedly sleeved on the outer wall of the roller body. The two ends of the rubber sleeve are respectively in abutting connection with the corresponding drainage covers on both sides. The diameter of the rubber sleeve is smaller closer to the two annular seats on both sides, and the overall shape is a gradually changing shape that is thick in the middle and thin at both ends.

[0009] Preferably, the rubber sleeve is made by mixing rubber, polyaniline, and polypyrrole materials.

[0010] Preferably, a cavity extending along the length direction of the roller shaft is provided in the middle of the roller shaft. An annular cavity extending along the length direction of the roller body is provided around the roller shaft within the roller body. A plurality of flow holes are evenly distributed at both ends of the cavity on the roller shaft. The flow holes are used to connect the corresponding sides of the cavity and the annular cavity. Water is contained in the cavity and the annular cavity. An annular piston seat distributed around the roller shaft is slidably installed in the annular cavity. An annular electromagnet seat for magnetically attracting the annular piston seat is installed on the side end wall of the annular cavity. By the translational sliding of the annular piston seat in the cavity, the water can be pushed to flow in the flow path composed of the cavity, the annular cavity, and the flow holes.

[0011] Preferably, there are two annular electromagnet seats, which are respectively fixed on the two side end walls of the annular cavity and are distributed on both sides of the annular piston seat. Metal sheets magnetically attracted to the annular electromagnet seats are embedded on both sides of the annular piston seat.

[0012] Preferably, reset springs are fixed on both sides of the annular piston seat. The reset springs all extend along the length direction of the roller shaft, and the other ends of the reset springs are fixedly connected to the corresponding annular electromagnet seats.

[0013] Preferably, cavities are provided on both sides of the cavity in the roller shaft. A heat conduction rod is coaxially fixed on the cavity. The two ends of the heat conduction rod respectively penetrate and extend into the corresponding cavities. A plurality of heat conduction fins are annularly and evenly distributed on both ends of the roller shaft. The heat conduction fins correspondingly penetrate and extend into the cavities and are in abutting connection with the outer surface of the heat conduction rod.

[0014] Preferably, the anti-static heating device for the rubber roller of this drawing frame further includes a pair of annular ion air bars. The two annular ion air bars are respectively installed on the mounting frame of the drawing frame through mounting brackets and are symmetrically distributed on both sides of the roller shaft. The air holes of the two annular ion air bars on both sides are all directed towards the roller shaft.

[0015] Preferably, both the heat conduction rod and the heat conduction fins are made of aluminum.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0017] By installing drainage covers and turbine-type blades on the roller shaft in the present invention, two opposite transverse airflows are formed. Combining with the rubber sleeve provided on the outer wall of the roller body, the two airflows are combined to form an airflow flowing towards the periphery of the rubber roller, which can carry heat and blow away the dirt attached to the roller shaft, realizing effective heat dissipation and cleaning of the roller shaft.

[0018] In the present invention, the generated heat dissipation air flow flows along the outer wall of the rubber sleeve, which can heat the rubber sleeve. Heating can intensify the movement of rubber molecules, improve its elasticity and flexibility, ensure uniform and stable grip force on the fibers, reduce fiber slippage, and improve the effect of drawing and conveying fibers. In addition, by heating the rubber sleeve, the temperature of the fibers can rise when they come into contact, making them softer and easier to deform, thereby improving the spinnability of the fibers and the quality of the spun yarn.

[0019] In the present invention, by setting an annular piston seat, an annular electromagnet seat and a return spring, and alternately energizing and de-energizing the two annular electromagnet seats, the annular piston seat can reciprocate in the annular cavity for adjustment, so that the water body can be exchanged in the cavity and the annular cavity. On the one hand, it accelerates the discharge of heat in the roller shaft, and on the other hand, it can be used as heat supplement when the roller body and the rubber sleeve are heated. And the cavity is close to the rubber sleeve. Under the action of the peripheral heat dissipation air flow, the excessive accumulated heat can be transferred to the outer wall of the rubber sleeve and dissipated along with the air flow. At the same time, by setting annular electromagnet seats on both sides of the annular cavity, setting the annular piston seat in the middle of the two annular electromagnet seats, and connecting the two sides of the annular piston seat to the annular electromagnet seats respectively by using the return spring, when both annular electromagnet seats are de-energized, the annular piston seat can be pulled back to the middle by the elastic reset of the return spring, which can avoid the situation that the annular piston seat cannot be driven to move due to the too long stroke of the annular piston seat and the limited magnetic attraction range of the annular electromagnet seat. The overall structure layout is reasonable.

[0020] In the present invention, by setting an annular ion wind rod, a large number of air masses with positive and negative charges can be generated after the annular ion wind rod is connected to the high-pressure air pipe and opened, and are blown out from the air holes and mixed into the transverse air flow generated by the turbine blades to form an electrostatically charged air flow, which can remove static electricity from the textile strip and the outer wall of the rubber sleeve. This transverse air flow has a large coverage area on the rubber roller, effectively ensuring the range of static electricity removal.

[0021] While dissipating heat, the present invention can heat the roller body and the rubber sleeve by using the generated air flow and the flowing water body, improve the fiber conveying and forming effect, and the heat source is the heat source on the roller shaft, realizing the reuse of heat. Furthermore, no additional heating device needs to be set for the roller body and the rubber sleeve, reducing the manufacturing cost. Description of the Drawings

Specific embodiments

[0024] Please refer to Figures 1 - 9 , the present invention provides an anti-static heating device for a drawing frame rubber roller, and the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] In the description of the embodiments of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms, "connection", "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct communication or an indirect communication through an intermediate medium. Among them, "fixing" means that they are connected to each other and the relative positional relationship after connection remains unchanged. The orientation terms mentioned in the embodiments of the present invention, for example, "inside", "outside", "top", "bottom", etc., are only for reference to the direction of the accompanying drawings. Therefore, the orientation terms used are for better and clearer description and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present invention.

[0026] In the embodiments of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] In the embodiments of the present invention, "and / or" is merely an association relationship describing associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this text, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0028] References to "one embodiment" or "some embodiments" described in this specification mean that specific features, structures, or characteristics described in conjunction with that embodiment are included in one or more embodiments of the present invention. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way. The terms "comprising", "including", "having", and their variants all mean "including but not limited to", unless otherwise specifically emphasized in another way.

[0029] It should be noted that the rubber rollers of existing draw frames are mainly composed of a roller shaft 01 and a roller body 02. The roller body 02 is fixedly sleeved on the roller shaft 01. Both ends of the roller shaft 01 are respectively installed on bearing seats or bushings. In order to ensure the structural rigidity of the rubber roller, the roller shaft 01 is usually made of metal material, and the heating part is mainly concentrated at both ends of the roller shaft 01.

[0030] The antistatic heating device for the rubber roller of this draw frame includes a drainage cover 1, an annular seat 2, and turbine blades 3. Two drainage covers 1 are symmetrically and fixedly sleeved on the roller shaft 01. The two drainage covers 1 respectively abut against the two side ends of the roller body 02 sleeved on the roller shaft 01. Moreover, the diameter of the drainage cover 1 is relatively large, playing a role of blocking and limiting at both ends, and can prevent the product from falling off from both sides on the rubber roller.

[0031] Annular seats 2 are fixedly sleeved on the roller shaft 01 within the cavities of the two drainage covers 1. A number of turbine blades 3 are fixedly arranged in an annular array on the outer peripheral walls of the two annular seats 2. The turbine blades 3 on the two annular seats 2 on both sides are symmetrically arranged. A number of through air blowing openings 11 are arranged in an annular array around the roller shaft 01 on the mutually approaching side surfaces of the two drainage covers 1. That is, when the rubber roller rotates, the drainage cover 1, the annular seat 2, and the turbine blades 3 can rotate synchronously. The annular seat 2 evenly installs the turbine blades 3 on the roller shaft 01, as Figure 7 shown. The rotating turbine blades 3 can press the air flow at the shaft end of the roller shaft 01 into the drainage cover 1 and blow it out through the air blowing openings 11, forming a transverse air flow. Thus, in the length direction of the rubber roller, relative air flows are formed on both sides. The heat at both shaft ends of the roller shaft 01 moves along with the air flow, realizing effective heat dissipation of the shaft ends.

[0032] Among them, the cross-section of the turbine blade 3 is arc-shaped. The arc-shaped design facilitates the interception of air, and the turbine blades 3 all extend outside the diversion hood 1, having a larger contact surface with air and not being limited within the diversion hood 1, effectively improving the air capture effect, thereby ensuring that the generated flowing air is stronger.

[0033] In addition, a rubber sleeve 021 is fixedly sleeved on the outer wall of the roller body 02. The two ends of the rubber sleeve 021 are respectively in abutment with the corresponding sides of the two diversion hoods 1. The diameter of the rubber sleeve 021 is smaller closer to the two annular seats 2 at both sides, showing a gradually changing shape that is thicker in the middle and thinner at both ends, making the middle part of the rubber roller slightly bulged. As Figure 7 shown, the two airflows formed on both sides flow along the outer wall of the rubber sleeve 021. With the change of the shape of the outer wall of the rubber sleeve 021, the flow direction also changes accordingly, and the distance from the axis of the roller shaft 01 becomes farther and farther. After the two airflows converge in the middle of the rubber roller, a stable airflow flowing towards the periphery of the rubber roller is formed, and the heat is also discharged along this flow path. At the same time, the fiber debris, short fibers, and thread ends adhered to the outer wall of the rubber sleeve 021 are blown away, and the airflow finally moves away from the rubber roller, and the dirt will also move away from the rubber roller, avoiding secondary pollution.

[0034] In addition, the roller body 02 and the rubber sleeve 021 are made of materials such as rubber. At normal temperature, the elasticity and flexibility of rubber are insufficient. When dissipating heat, the heat dissipation airflow flows along the outer wall of the rubber sleeve 021, which can heat the rubber sleeve 021. Heating can make the rubber molecules move more intensively, improve its elasticity and flexibility, help the rubber roller better fit components such as rollers, ensure the uniform and stable holding force of the fibers, reduce the fiber slipping phenomenon, and thus improve the effect of drafting and conveying fibers.

[0035] In addition, some chemical fibers are relatively rigid at normal temperature and are not easy to draft and card. By heating the rubber sleeve 021, the temperature of the fibers can be increased when they come into contact, making them softer and easier to deform, thereby improving the spinnability of the fibers and the quality of the spun yarn.

[0036] In addition, it is worth noting that the heat at both ends of the roller shaft 01 will also be transferred to the middle of the roller shaft 01. Since the roller body 02 and the rubber sleeve 021 are made of materials such as rubber and have low thermal conductivity, the heat on the roller shaft 01 will accumulate excessively inside the roller shaft 01 and at the joint between the roller shaft 01 and the roller body 02 and is difficult to dissipate quickly. To solve this problem, the following improvements are made in this application: As Figure 5As shown in the figure, a channel 03 extending along the length direction is provided in the middle of the roller shaft 01. An annular cavity 04 extending along the length direction of the roller body 02 is provided around the roller shaft 01 within the roller body 02. A number of flow holes 05 are evenly distributed at both ends of the channel 03 on the roller shaft 01. The flow holes 05 are used to connect the corresponding sides of the channel 03 and the annular cavity 04. Water is contained in the channel 03 and the annular cavity 04. An annular piston seat 4 distributed around the roller shaft 01 is slidably installed in the annular cavity 04. An annular electromagnet seat 5 for magnetically attracting the annular piston seat 4 is installed on the side end wall of the annular cavity 04. By the translational sliding of the annular piston seat 4 in the channel 03, the water can be pushed to flow in the flow path composed of the channel 03, the annular cavity 04, and the flow holes 05. The water in the channel 03 can absorb the heat accumulated in the roller shaft 01. After entering the annular cavity 04 through the flow holes 05, the heat can be directly conducted into the roller body 02. On the one hand, it accelerates the discharge of the heat in the roller shaft 01. On the other hand, it can be used as the heat supplement when the roller body 02 and the rubber sleeve 021 are heated. And the channel 03 is close to the rubber sleeve 021. Under the action of the peripheral heat dissipation air flow, the excessive accumulated heat can be transferred to the outer wall of the rubber sleeve 021 and dissipated along with the air flow.

[0037] Through the design of the above technical solutions of the present application, the heat dissipation at the shaft end and the middle of the roller shaft 01 can be accelerated, and the service life of the entire rubber roller can be improved. In addition, during heat dissipation, the generated air flow and the flowing water can be used to heat the roller body 02 and the rubber sleeve 021, improving the fiber conveying and forming effects. And the heat source is the heat source on the roller shaft 01, realizing the reuse of heat. Furthermore, no additional heating device needs to be provided for the roller body 02 and the rubber sleeve 021, reducing the manufacturing cost.

[0038] As Figure 5 shown, there are two annular electromagnet seats 5. The two annular electromagnet seats 5 are respectively fixed on the two side end walls of the annular cavity 04 and are distributed on both sides of the annular piston seat 4. Metal sheets 41 magnetically attracted to the annular electromagnet seats 5 are embedded on both sides of the annular piston seat 4. That is, by alternately energizing and de-energizing the two annular electromagnet seats 5 on both sides and under the action of magnetic attraction with the metal sheets 41, the annular piston seat 4 can reciprocate in the channel 03. Reset springs 6 are fixed on both sides of the annular piston seat 4. The reset springs 6 all extend along the length direction of the roller shaft 01. The other ends of the reset springs 6 are fixedly connected to the corresponding annular electromagnet seats 5.

[0039] Define one of the annular electromagnet seats 5 as electromagnet seat A and the other annular electromagnet seat 5 as electromagnet seat B. As Figure 8As shown in the figure, when the electromagnet seat A is powered on and the electromagnet seat B is powered off, under the magnetic attraction of the electromagnet seat A and the metal sheet 41 on the side of the annular piston seat 4 close to the electromagnet seat A, the annular piston seat 4 is attracted to the side of the electromagnet seat A. At this time, the return spring 6 on the side close to the electromagnet seat A is compressed and stores energy, and the return spring 6 on the other side is stretched and stores energy. The annular piston seat 4 presses the water in the channel 03 into the channel 03 through the flow hole 05 on the side close to the electromagnet seat A, and the water in the channel 03 flows into the annular cavity 04 through the flow hole 05 on the side far from the electromagnet seat A, as Figure 8 shown. When the battery iron seat B is powered on and the battery iron seat A is powered off, the movement principle of the annular piston seat 4 is the same as above, thereby realizing the exchange of water in the channel 03 and the annular cavity 04. After the water in the channel 03 absorbs the heat on the roller shaft 01, it then enters the annular cavity 04 and transfers the heat to the roller body 02, thus accelerating the heat transfer. Moreover, the annular cavity 04 is designed in a ring shape, and the heat-absorbing water is evenly distributed in the annular cavity 04, ensuring that each part of the roller body 02 and the rubber sleeve 021 is heated evenly and improving the heating effect on the roller body 02 and the rubber sleeve 021.

[0040] In addition, by arranging annular electromagnet seats 5 on both sides of the annular cavity 04, setting the annular piston seat 4 in the middle of the two annular electromagnet seats 5, and connecting the two sides of the annular piston seat 4 to the annular electromagnet seats 5 respectively by using the return spring 6, when both annular electromagnet seats 5 are powered off, the return spring 6 can be used to elastically reset and pull the annular piston seat 4 back to the middle position, which can avoid the situation that the annular piston seat 4 cannot be driven to move due to the excessive stroke of the annular piston seat 4 and the limited magnetic attraction range of the annular electromagnet seat 5. The overall structure layout is reasonable.

[0041] As Figure 5 shown, cavities 06 are provided on both sides of the channel 03 inside the roller shaft 01. A heat conduction rod 7 is coaxially fixed on the channel 03, and both ends of the heat conduction rod 7 penetrate and extend into the corresponding cavities 06 respectively. A number of heat conduction fins 8 are evenly distributed in a circular array on both ends of the roller shaft 01. The heat conduction fins 8 correspondingly penetrate and extend into the cavities 06 and are in contact with the outer surface of the heat conduction rod 7. Both the heat conduction rod 7 and the heat conduction fins 8 are made of aluminum.

[0042] The heat conduction fins 8 can absorb the heat at the shaft end of the roller shaft 01, transfer it to the heat conduction rod 7, and then the heat conduction rod 7 transfers the heat to the channel 03, and further transfers the heat directly to the water in the channel 03, further accelerating the heat transfer.

[0043] As Figure 1 and Figure 6As shown in the figure, the antistatic heating device for the rubber rollers of this drawing frame further includes a pair of annular ion blow bars 9. The two annular ion blow bars 9 are respectively installed on the mounting frame of the drawing frame through mounting brackets 92, and are symmetrically distributed on both sides of the roller shaft 01. The air holes 91 of the annular ion blow bars 9 on both sides all face the roller shaft 01. The annular ion blow bar 9 is the same as the ion blow bar device in the prior art, except that its shape is annular.

[0044] As Figure 7 shown in the figure, after the annular ion blow bar 9 is connected to the high-pressure air pipe and turned on, a large number of air masses with positive and negative charges can be generated, and are blown out from the air holes 91 and mixed into the transverse air flow generated by the turbine blades 3 to form an electrostatic air flow, which can remove static electricity from the textile sliver and the outer wall of the rubber sleeve 021. This transverse air flow has a large coverage area on the rubber roller, effectively ensuring the range of static electricity removal.

[0045] In addition, the rubber sleeve 021 is made of a mixture of rubber, polyaniline and polypyrrole materials. Polyaniline has a unique doping mechanism. During the heating process, the movement of its molecular chains intensifies, which is conducive to the conduction of charges. As the temperature rises, the charge transfer within and between molecules becomes easier, making the conductivity of the material increase, thereby enhancing the antistatic ability. Polypyrrole is a polymer material with good conductivity. When the temperature rises, the carrier mobility inside it increases, and it can conduct static charges more quickly, thereby further improving the antistatic effect of the rubber roller.

[0046] It should be noted that Figure 7 the solid-line arrow in the figure indicates the movement direction of the charged air mass blown out from the air hole 91, and the dashed-line arrow indicates the air flow direction generated by the turbine blades 3. Figure 8 and Figure 9 the solid-line arrow in the figure indicates the movement direction of the annular piston seat 4, and the dashed-line arrow indicates the water flow direction.

[0047] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
