Description

Technical Field

[0001] This invention belongs to the field of heat insulation fabric processing technology, and in particular relates to a heat treatment processing device for heat insulation fabric. Background Technology

[0002] Generally, in the subsequent processing of thermal insulation fabrics, a heat treatment and shaping step is required. This involves using high-temperature electric heating or steam spraying to shape the fabric into a relatively stable state. After shaping, the physical and chemical properties of the fabric are more stable, such as shrinkage, width, and warp and weft density, which are less likely to change. The fabric surface is also smoother and more aesthetically pleasing.

[0003] However, during the process of heat-sealing multiple layers of fabric into one layer through extrusion heat sealing, the surface of the fabric is prone to shrinkage, resulting in wrinkles and twists. If not effectively treated, the surface smoothness of the fabric will be poor, thus affecting the production quality of the fabric. This not only increases production costs but also affects the performance of the heat insulation fabric. Therefore, we designed a heat treatment processing device for heat insulation fabric. Summary of the Invention

[0004] The purpose of this invention is to provide a heat treatment processing apparatus for heat-insulating fabrics in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A heat treatment processing device for heat-insulating fabric includes a base, a processing chamber fixedly disposed on the upper end face of the base, and a heat treatment mechanism. The base is provided with a heating chamber inside, and an electric heating plate is fixedly disposed on the inner wall of the top of the heating chamber.

[0007] The heat treatment mechanism includes a drive unit and a pressure assembly;

[0008] The pressing assembly includes two piston cylinders located opposite each other at the top of the processing chamber, a piston movably located inside the two piston cylinders, a connecting rod fixed between the two pistons, a fork fixed on the connecting rod, four sets of spring assemblies, and a roller frame. The upper end face of the roller frame is fixed to both sides of the port of the fork by a set of spring assemblies at the four corners. Multiple rolling rollers are rotatably arranged in sequence inside the port of the roller frame.

[0009] The drive unit includes two piston cylinders fixedly mounted on the heating chamber, a pressure pipe fixedly mounted on one side of the heating chamber, and an electromagnetic valve fixedly mounted on the two pressure pipes. The other ends of the two pressure pipes are respectively fixedly connected to the inlet end of the piston cylinders. The interior of the heating chamber is filled with a thermal expansion medium.

[0010] As a further optimization of the present invention, each set of spring assemblies includes a movable column, a sleeve that slides on the movable column, a connector fixed at the other end of the movable column, and a reset spring fixed between the connector and the inner side of the sleeve, wherein the reset spring is movably sleeved on the movable column.

[0011] As a further optimization of the present invention, the four sets of spring assemblies are respectively arranged in an inverted V-shape on both sides of the port of the fork, and the other end of the connector and the other end of the sleeve are respectively rotatably mounted on the fork and the roller frame via a rotating shaft.

[0012] As a further optimization of the present invention, the thermal expansion medium is one of carbon dioxide, helium, hydrogen or air.

[0013] As a further optimization of the present invention, the heat treatment mechanism further includes a limiting and guiding assembly, which includes guide rods that are fixedly and parallel to both sides of the inside of the treatment chamber and collars that are fixedly and parallel to both sides of the fork rod. The two collars are respectively sleeved on the two guide rods to ensure the stability of the sliding.

[0014] As a further optimization of the present invention, the device further includes a preheating component, and the upper end surface and the bottom end surface of the base are respectively fixed with a first frame plate and a second frame plate;

[0015] The preheating assembly includes a heat-conducting channel fixedly mounted on the second frame plate, an exhaust fan fixedly mounted inside the heat-conducting channel, and a fixed bracket fixedly mounted on one side of the frame plate. A heat-conducting pipe and an exhaust pipe are fixedly mounted at both ends of the heat-conducting channel, respectively. The other end of the heat-conducting pipe is fixedly mounted on the fixed bracket in a U-shape, and heat-conducting ports are opened on the opposite sides. The other end of the heat-conducting channel is fixedly connected to the heating chamber through the exhaust pipe.

[0016] As a further optimization of the present invention, the drive unit further includes a second electromagnetic valve, a PLC control module, and a timing module connected to the PLC control module. The second electromagnetic valve is located on the exhaust pipe, and the first electromagnetic valve, the second electromagnetic valve, and the exhaust fan are respectively connected to the timing module.

[0017] As a further optimization of the present invention, the heating chamber is equipped with a temperature monitoring module, which is connected to the PLC control module via signal connection, and the PLC control module is connected to an early warning module via signal connection.

[0018] The beneficial effects of this invention are as follows:

[0019] 1) In this invention, heat is generated by the resistance wire inside the electric heating plate, which raises the temperature inside the heating chamber. The thermal expansion medium inside the heating chamber expands after being heated. At this time, according to the settings of the PLC control module, the electromagnetic valve on the right pressure pipe is opened and the electromagnetic valve on the left pressure pipe is closed. Under the action of air pressure, the piston located at the outlet slot on the right side is pushed, so that the connecting rod, along with the fork rod, spring assembly and multiple rolling rollers, slides horizontally to the left. After the set time is reached, the electromagnetic valve on the left pressure pipe is opened and the electromagnetic valve on the right pressure pipe is closed, realizing the reciprocating motion. Under the action of multiple rolling rollers, the heat insulation fabric is effectively pressed back and forth, improving the stability of the fabric adhesive and the surface flatness of the heat insulation fabric, thereby preventing wrinkles and separation.

[0020] 2) In this invention, after one or more reciprocating motions are completed, the electromagnetic valve on the exhaust pipe is opened by the PLC control module and the exhaust fan is started. At this time, the hot air inside the heating chamber is drawn out and placed on the fabric under the negative pressure of the exhaust fan blades, thereby achieving double-sided preheating treatment of the bottom and top of the heat insulation fabric, making the fabric surface smoother during rolling and effectively improving the stability of heat treatment.

[0021] 3) This invention utilizes a temperature monitoring module to monitor the temperature inside the heating chamber in real time, preventing excessive temperature and pressure. When the temperature or / and pressure is too high, the warning module issues a warning, and the PLC control module controls the opening time of the second solenoid valve and increases the power of the exhaust fan to relieve pressure, thereby ensuring that the pressure / temperature inside the heating chamber is within a certain range and guaranteeing the normal operation of the equipment.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Combined with appendix Figure 1 , 23.5 Implementation: A heat treatment processing device for heat-insulating fabric includes a base 2, a processing chamber 3 fixedly disposed on the upper end face of the base 2, and a heat treatment mechanism. The base 2 has a heating chamber 25 inside, and an electric heating plate 251 is fixedly disposed on the inner wall of the top of the heating chamber 25. The heat treatment mechanism includes a drive unit 41 and a pressing assembly. The pressing assembly includes two piston cylinders 421 disposed opposite to each other at the top of the processing chamber 3, a piston 422 movably disposed within the two piston cylinders 421, a connecting rod 423 fixed between the two pistons 422, a fork 424 fixedly disposed on the connecting rod 423, four sets of spring assemblies 425, and a roller frame 426. A spring is passed through each of the four corners of the upper end face of the roller frame 426. A spring assembly 425 is fixedly mounted on both sides of the port of the fork 424. Multiple rolling rollers 427 are rotatably mounted in sequence inside the port of the roller frame 426. The drive unit 41 includes two piston cylinders 421 fixedly mounted on the heating chamber 25, a pressure pipe 411 fixedly mounted on one side of the heating chamber, and an electromagnetic valve 412 fixedly mounted on the two pressure pipes 411. The other ends of the two pressure pipes 411 are fixedly connected to the inlet end of the piston cylinders 421 respectively. The interior of the heating chamber 25 is filled with a thermal expansion medium. A set of auxiliary pressure rollers 21 and 22 distributed vertically are respectively mounted on both sides of the base 2. An inlet groove 31 and an outlet groove 32 are respectively mounted on both sides of the heating chamber 25.

[0037] In the initial state, the resistance wire inside the electric heating plate 251 generates heat, causing the temperature inside the heating chamber 25 to rise. The thermal expansion medium inside the heating chamber 25 expands upon heating. At this time, according to the settings of the PLC control module 414, the solenoid valve 412 on the right pressure pipe 411 is opened, and the solenoid valve 412 on the left pressure pipe 411 is closed. Under the action of air pressure, the piston 422 located at the outlet 32, i.e., on the right, is pushed, causing the connecting rod 423, along with the fork 424, the spring assembly 425, and multiple rolling rollers 427, to slide horizontally to the left. After the set time is reached, the solenoid valve 412 on the left pressure pipe 411 is opened, and the solenoid valve 412 on the right pressure pipe 411 is closed, realizing the reciprocating motion.

[0038] After the heat insulation fabric is introduced into the processing chamber 3 through a set of auxiliary pressure rollers 21, 22 and 31 on the side of the base 2, it is effectively pressed back and forth by multiple pressing rollers 427 to improve the stability of the fabric adhesive and the smoothness of the heat insulation fabric surface, thereby preventing wrinkles and separation.

[0039] Combined with the appendix Figure 2 , 5As a further optimized implementation of Embodiment 1 of the present invention, each set of spring assemblies 425 includes a movable column 4251, a sleeve 4252 slidably sleeved on the movable column 4251, a connector 4253 fixedly disposed at the other end of the movable column 4251, and a reset spring 4254 fixedly disposed between the inner sides of the connector 4253 and the sleeve 4252. The reset spring 4254 is movably sleeved on the movable column 4251. The four sets of spring assemblies 425 are respectively arranged in pairs in an inverted V-shape on both sides of the port of the fork 424. The other ends of the connector 4253 and the other ends of the sleeve 4252 are respectively rotatably disposed on the fork 424 via a rotating shaft. The roller frame 426 is used as the heat expansion medium, which is one of carbon dioxide, helium, hydrogen or air. The heat treatment mechanism also includes a limiting guide assembly 43, which includes guide rods 431 that are fixedly and parallel to each other on both sides of the inside of the treatment chamber 3 and collars 432 that are fixedly and parallel to each other on both sides of the fork rod 424. The two collars 432 are respectively sleeved on the two guide rods 431. With the above design, the figure-eight shaped spring assembly 425 can adapt to the pressing of heat insulation fabrics of different thicknesses. At the same time, the collars 432 and the guide rods 431 are used to limit the movement, thereby ensuring the stability of the sliding.

[0040] Example 2

[0041] Based on Example 1, and further combined with Appendix Figure 1 , 4 A further implementation of the scheme is as follows: The device also includes a preheating component. A first frame plate 23 and a second frame plate 24 are fixedly mounted on the upper and lower surfaces of the base 2, respectively. The preheating component includes a heat-conducting channel 11 fixed on the second frame plate 24, an exhaust fan 14 fixed inside the heat-conducting channel 11, and a fixed bracket 15 fixed on the side of the first frame plate 23. A heat-conducting pipe 12 and an exhaust pipe 13 are fixedly mounted at both ends of the heat-conducting channel 11, respectively. The other end of the heat-conducting pipe 12 is fixedly mounted on the fixed bracket 15 in a U-shape, and heat-conducting ports 121 are opened on opposite sides. The other end of the heat-conducting channel 11 is connected to the exhaust fan 13. Pipe 13 is fixedly connected to heating chamber 25; drive unit 41 also includes solenoid valve 2 413, PLC control module 414 and timing module 415 connected to PLC control module 414 by signal. Solenoid valve 2 413 is installed on exhaust pipe 13. Solenoid valve 1 412, solenoid valve 2 413 and exhaust fan 14 are respectively connected to timing module 415 by signal. Temperature monitoring module 416 is installed inside heating chamber 25. Temperature monitoring module 416 is connected to PLC control module 414 by signal. PLC control module 414 is connected to early warning module 417 by signal.

[0042] After one or more reciprocating motions are completed, the timing module 415 sends an end signal to the PLC control module 414. The PLC control module 414 then controls the opening of the solenoid valve 413 on the exhaust pipe 13 and controls the start of the exhaust fan 14. At this time, under the negative pressure of the exhaust fan 14 blades, the hot air inside the heating chamber 25 is extracted and discharged from the heat conduction port 121 through the heat conduction pipe 12. This achieves double-sided preheating treatment of the bottom and top of the heat insulation fabric, making the fabric surface smoother during rolling and effectively improving the stability of the heat treatment.

[0043] Based on the pressure changes of the thermal expansion medium and the temperature changes within the heating layer, the temperature monitoring module 416 is used to monitor the temperature inside the heating chamber 25 in real time to prevent excessive temperature and pressure. When the temperature or / and pressure is too high, the early warning module 417 issues an early warning, and the PLC control module 414 controls the opening time of the solenoid valve 413 and increases the power of the exhaust fan 14 to relieve pressure, thereby ensuring that the pressure / temperature inside the heating chamber 25 is within a certain range and ensuring the normal operation of the equipment.

[0044] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
