Description

Technical Field

[0001] The present invention relates to the technical field of textile printing and dyeing finishing machinery, and particularly relates to an ironing and polishing roller for textiles and an ironing and polishing machine. Background Art

[0002] In the textile printing and dyeing industry, it is necessary to perform ironing and polishing treatment on fabrics in the post-finishing process to increase the surface gloss, hand feeling, and visual appearance of the fabrics, etc., and improve the quality of the fabrics. An ironing and polishing machine is a device for performing ironing and polishing treatment on fabrics. The ironing and polishing roller is an important component of the ironing and polishing machine. Whether the temperature of the ironing and polishing roller is uniform has a direct impact on the quality of the ironing and polishing effect.

[0003] Existing ironing and polishing rollers include gas-type ironing and polishing rollers, oil-heated ironing and polishing rollers, electric-heated ironing and polishing rollers, etc. The gas-type ironing and polishing roller is provided with a gas pipe in the roller body. The gas pipe is connected to a gas source. After the gas enters the gas pipe, it burns to generate heat to heat the roller body. The surface temperature of the ironing and polishing roller heated by gas is uniform, but gas has an explosion risk and it is difficult to ensure safety, so it is not advocated by the industry; the Chinese patent with the publication number CN202969046U discloses an ironing and polishing mechanism of an ironing and polishing machine, which adopts circulating heating of heat-conducting oil to improve the uniformity of the surface temperature of the roller body. The circulation of the heat-conducting oil requires an external circulation oil circuit and a power source to provide circulation power. An external heating device is required to heat the power oil, and a hot air circulation heat exchange device is also required to circulate and heat the hot air in the heating cavity of the roller body and achieve convection. More driving mechanisms need to be set and the volume is large; the Chinese patent with the authorization publication number CN201473762U discloses a novel structure ironing and polishing roller body. An electric heating tube bracket is arranged in the roller shell of the roller body, and a group of electric heating tubes are arranged at intervals around the circumference of the electric heating tube bracket. The roller body roller shell is heated by the electric heating tubes. After the electric heating tubes generate heat, they directly heat the contact part of the roller body. This direct heating method will cause the temperature of the roller body to be uneven, that is, the temperature at the distribution part of the electric heating tubes is higher than the temperature at the gap where the electric heating tubes are arranged. Summary of the Invention

[0004] Aiming at the disadvantages that the existing oil-heated ironing and polishing rollers require many driving mechanisms and the electric-heated ironing and polishing rollers have uneven heating, the first object of the present invention is to provide an ironing and polishing roller for textiles with uniform heating and few driving mechanisms.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A textile polishing roller comprises a roller body and an electric heating component arranged in the roller body, wherein the electric heating component is arranged in a mounting component, one end of the mounting component extends to the outside of the roller body and is fixed to a fixed position, the roller body is sealed and rotatably arranged outside the mounting component, and a heating chamber in contact with the entire inner surface of the roller body is formed between the roller body and the mounting component, a heating medium is arranged in the heating chamber, a first stirring component which can stir the heating medium along the axial direction of the roller body is arranged on the mounting component, and a linkage component which drives the first stirring component when the roller body rotates is arranged between the mounting component and the roller body.

[0007] By adopting the above scheme, a mounting component is arranged in the roller body and the roller body can rotate relative to the mounting component. An electric heating component is arranged in the mounting component. When the roller body rotates, the mounting component is relatively stationary, which can prevent the rotation of the roller body from involving the line of the electric heating component. A heating chamber is arranged between the roller body and the mounting component, and a heating medium is built in. After the electric heating component heats the heating medium, the heating medium conducts the heat to the roller body, and directly heats the roller body relative to the electric heating component, which can improve the uniformity of heating. A first stirring component is arranged, and the first stirring component is synchronously driven by a power source that drives the roller body to rotate. There is no need to add a power mechanism, which can reduce the setting cost. The first stirring component can stir the heating medium along the axial direction of the roller body. When the roller body rotates relative to the mounting component, the first stirring component can also stir the heating medium in a circumferential direction. Therefore, the convection of the heating medium in the heating chamber can be increased, thereby making the temperature of the heating medium quickly uniform, and evenly distributing heat conduction to the entire roller surface. The ironing roller can significantly improve the uniformity of heating on the roller surface, and only one driving force is required to drive the roller body to rotate, which can reduce the setting cost and reduce the volume.

[0008] Preferably, the first stirring component comprises transmission gears rotatably arranged on the outer wall of the mounting component at both ends of the roller body, a tooth chain meshed between the two transmission gears, and stirring blades protruding at intervals around the tooth chain in the circumferential direction.

[0009] By adopting the above scheme, the rotation of the transmission gear can drive the gear transmission, and then drive the stirring blade to move. The stirring blade moves around the running direction of the tooth chain, and can achieve reciprocating movement along the axial direction of the roller body, thereby realizing convection of the heating medium at both ends of the heating chamber.

[0010] Preferably, the linkage component includes a rotating shaft rotatably arranged on the outer wall of the mounting component, a driven bevel gear arranged on the rotating shaft, and a driving bevel gear protruding from the end of the roller body and meshing with the driven bevel gear, and the transmission gear is arranged on the rotating shaft and located at the end of the driven bevel gear away from the mounting component.

[0011] With the above solution, when the roller body rotates, the driving bevel gear integrally provided with the roller body rotates to drive the driven bevel gear to rotate. The driven bevel gear and the transmission gear are synchronously arranged on the rotating shaft. Therefore, the driven bevel gear rotates to drive the transmission gear to rotate, realizing the transmission of the tooth chain, and the stirring blades stir the heating medium during the transmission of the tooth chain.

[0012] Preferably, more than one set of the first stirring components are circumferentially spaced apart around the mounting component.

[0013] Preferably, a second stirring component is convexly provided on the outer wall of the mounting component along the axial direction of the roller body.

[0014] With the above solution, the second stirring component is convexly provided along the axial direction of the roller body. When the roller body rotates relative to the mounting component, the heating medium in the heating chamber can be stirred by the second stirring component, further accelerating the convection of the heating medium and ensuring the rapid mixing of the heating medium.

[0015] Preferably, the electric heating assembly includes heating tubes circumferentially spaced apart around the rotation center of the roller body and electric wires with one end connected to the heating tubes and the other end led out to the outside of the roller body. The mounting component includes a receiving portion for positioning and accommodating the heating tubes and a fixed tube with one end connected to the receiving portion and the other end extending beyond the end of the roller body. The end of the electric wire away from the heating tube passes out of the roller body through the inside of the fixed tube.

[0016] With the above solution, the receiving portion is used to install and position the heating tubes, and the fixed tube is used to lead out the electric wires connected to the heating tubes, avoiding the influence of the rotation of the roller body on the electric wires.

[0017] Preferably, a pressure relief structure for relieving the pressure in the heating chamber is provided inside the roller body. The pressure relief mechanism includes a piston sealingly moving inside the fixed tube. Both ends of the fixed tube penetrate through both ends of the roller body. There are two sets of receiving portions sleeved and fixed on the fixed tube. There is a fitting gap on the opposite sides of the receiving portions. A through groove communicating with the inside of the fixed tube is provided on the fixed tube at the fitting gap. There are two pistons located on both sides of the fitting gap.

[0018] With the above solution, the heating medium will expand by a certain volume when heated, and excessive pressure poses a safety hazard. The pressure relief structure is provided. By using the reciprocating movement of the piston inside the fixed tube, the volume of the heating chamber can be adaptively expanded during heating and adaptively reset during cooling, which can relieve the problem of excessive internal pressure caused by the thermal expansion of the heating medium.

[0019] Preferably, an elastic member for driving the piston to approach the fitting gap is provided on the fixed tube. A mounting plate is convexly provided inside the fixed tube. Both ends of the elastic member are fixedly connected to the mounting plate and the piston respectively.

[0020] With the above solution, the elastic member can accelerate the automatic reset of the piston. The mounting plate can not only provide support for the arrangement of the elastic member, but also limit the excessive backward movement of the piston.

[0021] Preferably, the heating medium is a liquid heat-conducting medium or a gaseous heat-conducting medium.

[0022] With the above solution, both the liquid heat-conducting medium and the gaseous heat-conducting medium can be applied to the present ironing roller to conduct heat to the roller body.

[0023] The second object of the present invention is to provide an ironing roller, which has the above-mentioned textile ironing roller. The two ends of the roller body extend outwards with mating pipes, and a pulley or a gear is coaxially fixed on the mating pipes.

[0024] With the above solution, the mating pipe is connected to the roller body, and a pulley or a gear is arranged on the mating pipe. It can be connected to the pulley or gear on the driving motor through a synchronous belt or a toothed chain, so that the roller body can be rotated under the drive of the driving motor.

[0025] Due to the adoption of the above technical solutions, the present invention has remarkable technical effects:

[0026] 1. An installation component is arranged in the roller body and the roller body can rotate relative to the installation component. An electric heating component is arranged in the installation component. When the roller body rotates, the installation component remains stationary, which can avoid the rotation of the roller body from involving the circuit of the electric heating component. A heating chamber is arranged between the roller body and the installation component, and a heating medium is arranged therein. After the electric heating component heats the heating medium, the heating medium conducts the heat to the roller body. Compared with directly heating the roller body by the electric heating component, it can improve the heating uniformity. And a first stirring component is arranged, which is synchronously driven by the power source that drives the roller body to rotate. There is no need to add a power mechanism, which can reduce the setting cost. The arranged first stirring component can stir the heating medium along the axial direction of the roller body. When the roller body rotates relative to the installation component, the first stirring component can also stir the heating medium circumferentially. Therefore, the convection of the heating medium in the heating chamber can be increased, so that the temperature of the heating medium is unified, and the heat is evenly conducted to the entire surface of the roller body. This ironing roller can significantly improve the uniformity of heat reception on the surface of the roller body, and only requires a driving force to drive the roller body to rotate, which can reduce the setting cost and reduce the volume;

[0027] 2. When the heating medium is heated, it will expand by a certain volume, and excessive pressure poses a safety hazard. A pressure relief structure is arranged, and by using the reciprocating movement of the piston in the fixed pipe, the volume of the heating chamber can be adaptively expanded during heating and the volume of the heating chamber can be adaptively reset during cooling. This setting can relieve the problem of excessive internal pressure caused by the thermal expansion of the heating medium. Description of the Drawings

Detailed implementation manners

[0035] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0036] Embodiment

[0037] An ironing machine includes a textile ironing roller. Referring to Figures 1-6 as shown, the textile ironing roller includes a roller body 1 and an electric heating assembly disposed inside the roller body 1. Both ends of the roller body 1 are open and are hermetically connected through a sealing end cover 15. A mating pipe 102 protrudes centrally from the outer wall of the sealing end cover 15. A pulley 2 or a gear is coaxially fixed on the outer wall of the mating pipe 102. In this embodiment, a pulley 2 is adopted. The pulley 2 and the pulley 2 on the motor shaft of the driving motor are synchronously rotated through a transmission belt.

[0038] Combined with Figure 2 and Figure 3As shown in the figure, the electric heating component includes heating tubes 12 circumferentially and spaced apart around the rotation center of the roller body 1, and electric wires 4 with one end connected to the heating tubes 12 and the other end led out of the roller body 1. The electric heating component is arranged in an installation component. The installation component and the sealing end cover 15 are rotationally and sealingly fitted through a sealing ring and a bearing. A heating chamber 101 in contact with the entire inner surface of the roller body 1 is formed between the installation component and the roller body 1. The heating chamber 101 is filled with a heating medium, and the heating medium is a liquid heat-conducting medium or a gaseous heat-conducting medium. In this embodiment, the heat-conducting oil is used.

[0039] The installation component includes a receiving part for positioning and receiving the heating tubes 12 and a fixed tube 3 with one end connected to the receiving part and the other end extending beyond the end of the roller body 1. The end of the fixed tube 3 is fixed on the frame of the calendering machine. Both ends of the fixed tube 3 penetrate through the sealing end cover 15 and are rotationally and sealingly fitted with the sealing end cover 15. There are two groups of receiving parts, which are annular containers 5 with opposite openings. The annular containers 5 are hermetically sleeved and fixed on the fixed tube 3. There is a fitting gap between the annular containers 5. A sealing cover 51 for closing the annular container 5 is fixed at the opening of the annular container 5. The heating tubes 12 are inserted and fixed on the sealing cover 51. A through groove 31 through which the electric wire 4 can pass into the fixed tube 3 is provided on the fixed tube 3. The end of the electric wire 4 far from the heating tube 12 enters the fixed tube 3 and is uniformly led out from the end of the fixed tube 3. A sealing component for isolating the electric wire 4 from the heat-conducting oil is arranged between the fixed tube 3 and the sealing cover 51. The sealing component includes a sealing retaining cover 14 hermetically sleeved and fixed on the fixed tube 3 and a sealing sleeve 13 sleeved on the fixed tube 3 and hermetically connected to the sealing retaining cover 14 and the sealing cover 51 at both ends. The through groove 31 is located inside the sealing sleeve 13.

[0040] Refer to Figure 6 As shown in the figure, a first stirring component for stirring the heating medium along the axial direction of the roller body 1 is arranged on the installation component. The first stirring component includes driving gears 10 rotatably arranged at both ends of the roller body 1 on the outer wall of the installation component, a toothed chain 11 meshing between the two driving gears 10, and stirring blades 18 protruding circumferentially and spaced apart around the toothed chain 11. In this embodiment, the driving gears 10 are located outside the sealing sleeve 13.

[0041] Refer to Figure 3 and Figure 6As shown, a linkage component is provided between the mounting component and the roller body 1 to drive the first stirring component when the roller body 1 rotates. The linkage component includes a rotating shaft 16 rotatably arranged with the fixed pipe 3. The rotating shaft 16 penetrates out of the sealing sleeve 13 and is in sealed rotational fit with the sealing sleeve 13. A transmission gear 10 is coaxially fixed on the rotating shaft 16 and is located outside the sealing sleeve 13. A driven bevel gear 9 is coaxially fixed on the rotating shaft 16 inside the sealing sleeve 13. A driving bevel gear 8 meshing with the driven bevel gear 9 is convexly provided on the sealing end cover 15. The fixed pipe 3 is in plug-in fit with the driving bevel gear 8 and is in sealed rotational fit through a sealing ring and a bearing. Two groups of the first stirring components are symmetrically arranged around the mounting component, and the driven bevel gears 9 of the two groups of the first stirring components are simultaneously meshed with a driving bevel gear 8.

[0042] On the outer wall of the mounting component, a second stirring component 19 is convexly provided along the axial direction of the roller body 1. The second stirring component 19 is a stirring plate convexly provided on the outer wall of the sealing sleeve 13 and the outer wall of the annular container 5.

[0043] A pressure relief structure for relieving the pressure in the heating chamber 101 is provided inside the roller body 1. Refer to Figure 4 As shown, the pressure relief mechanism includes a piston 17 sealingly moving in the fixed pipe 3. A through groove 31 communicating with the inside of the fixed pipe 3 is provided on the fixed pipe 3 at the mating clearance. Two pistons 17 are provided and are located on both sides of the mating clearance. An elastic member 7 for driving the piston 17 to approach the mating clearance is provided on the fixed pipe 3. The elastic member 7 is a spring or a tension spring. A mounting plate 6 is convexly provided inside the fixed pipe 3. The two ends of the elastic member 7 are respectively fixedly connected with the mounting plate 6 and the piston 17.

[0044] A temperature controller is provided on the outer wall of the roller body 1. The temperature controller, the control switch of the heating pipe 12, and the drive motor for driving the roller body 1 to rotate are synchronously connected to the PLC controller. When the temperature controller detects that the surface temperature of the roller body reaches the preset upper limit, the controller controls the control switch to disconnect, and the heating pipe 12 stops heating; when the temperature controller detects that the surface temperature of the roller body is lower than the preset lower limit, the controller controls the control switch to close, and the heating pipe 12 starts heating.

[0045] The principle of uniform heating of the roller body 1 is as follows: When the roller body 1 rotates, since the mounting component is fixedly arranged, the roller body 1 and the mounting component are in relative rotational fit. The driving bevel gear 8 on the roller body 1 drives the driven bevel gear 9 rotatably arranged on the mounting component, and then drives the transmission gear 10 coaxially rotating with the driven bevel gear 9 to rotate, thereby realizing the reciprocating movement of the stirring blade 18 along the axial direction of the roller body 1 to stir the heat-conducting oil in the heating chamber 101. At the same time, the second stirring component 19 can further accelerate the uniform heating of the heat-conducting oil. Without setting another driving mechanism, the heat-conducting oil can be fully mixed, making the entire roller body 1 heated evenly.

[0046] Principle of space switching in the internal heating chamber 101 of the roller body 1: After the heating tube 12 is heated, the heat-conducting oil heats up. As the temperature rises, the volume of the heat-conducting oil increases, and the piston 17 moves towards the end of the roller body 1 under the action of pressure to increase the volume of the heating chamber 101; when the heating tube 12 is turned off, the heat-conducting oil cools down, and the piston 17 moves in the reverse direction under the action of pressure and the elastic member 7, and the volume of the heating chamber 101 returns to the initial state.

[0047] The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
