Description

Technical Field

[0001] The present invention relates to energy-saving and environment-friendly printing and dyeing equipment, and in particular to energy-saving and environment-friendly printing and dyeing equipment applied in the field of printing and dyeing equipment. Background Art

[0002] Printing and dyeing is a processing method, which is also a general term for pre-treatment, dyeing, printing, finishing, washing, etc. It is a processing method for textiles. During the dyeing process, a certain temperature needs to be maintained to achieve the best printing and dyeing effect. At the same time, a large amount of organic wastewater will be generated in the process of printing and dyeing. Direct discharge will cause serious eutrophication of water bodies. Therefore, energy conservation and emission reduction have always been the core improvement direction of the printing and dyeing industry.

[0003] The invention patent CN201310586822.8 specification discloses a printing and dyeing process, which adjusts the dyeing rate and the dyeing process to the optimal state by controlling each temperature section during the dyeing process, so that the printed and dyed products have good dyeing uniformity and high color fastness. The printing and dyeing process of the present invention is simple, can realize industrial large-scale production, can bring good economic benefits to the enterprise, and has broad prospects.

[0004] In the above invention application, the purpose of increasing the printing and dyeing effect is achieved by controlling the printing and dyeing temperature. However, as printing and dyeing is a processing method that requires large-scale production equipment, existing sensor detection is difficult to achieve temperature monitoring of the entire printing and dyeing equipment. Even if a sensor group composed of multiple sensors is used to solve the problem of detection accuracy to a certain extent, the result of fixed-point detection is difficult to provide feedback data on power changes for the temperature control system of the printing and dyeing equipment. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing sensor detection is difficult to achieve temperature monitoring of the entire printing and dyeing equipment. Even if a sensor group composed of multiple sensors can solve the problem of detection accuracy to a certain extent, the result of fixed-point detection is difficult to provide feedback data of power changes for the temperature control system of the printing and dyeing equipment.

[0006] In order to solve the above problems, the present invention provides an energy-saving and environmentally friendly printing and dyeing processing equipment, comprising a plurality of conduction rollers matched with the positions of the printing and dyeing pool, the conduction rollers are wound with materials to be printed and dyed, the printing and dyeing pool contains printing and dyeing liquid, and the materials to be printed and dyed are immersed in the printing and dyeing liquid under the action of the plurality of conduction rollers, the printing and dyeing pool comprises an insulating pool body, an electric heating plate is fixedly connected to the bottom plate of the insulating pool body, a power end is rotatably connected to the bottom plate of the printing and dyeing pool, a transmission shaft is fixedly connected to the outer wall of the power end, and a plurality of stirring blades are fixedly connected to the outer wall of the transmission shaft;

[0007] A plurality of temperature detection units are mixed in the printing and dyeing liquid, and the plurality of temperature detection units slowly fall in the printing and dyeing liquid. The temperature detection unit comprises an elastic shell, a detection through hole is drilled on the elastic shell, and both end openings of the detection through hole are fixedly connected with limit rings matching the through hole, a movable piston matching the through hole is slidably connected in the detection through hole, a temperature sensor group is fixedly connected in the movable piston, compression springs are fixedly connected between the two ends of the movable piston and the two limit rings respectively, a buffer cavity is drilled in the elastic shell, the buffer cavity is filled with printing and dyeing liquid, the buffer cavity is filled with a plurality of buffer balls, and the plurality of buffer balls are suspended in the printing and dyeing liquid filled in the buffer cavity.

[0008] In the above-mentioned energy-saving and environmentally friendly printing and dyeing processing equipment, through the cooperation of the stirring paddle and the temperature detection unit, on the one hand, the temperature of different positions of the printing and dyeing liquid can be detected to increase the accuracy of temperature detection; on the other hand, the detection data fed back by the temperature detection unit can be used to judge the temperature in the printing and dyeing liquid, thereby controlling the electric heating plate and the stirring paddle to achieve the best working state and reduce excessive energy loss.

[0009] As a further improvement of the present application, the outer walls of multiple buffer balls are coated with a magnetic coating of the same level, and the inner wall of the detection through hole is fixedly connected with a reinforcing net. The presence of the reinforcing net can increase the strength of the elastic shell, so that the elastic shell is not easily damaged by the impact of the stirring paddle. After the temperature detection unit is knocked away, under the action of the magnetic coating of the same level, the multiple buffer balls will disperse from each other and restore the buffering effect.

[0010] As a further improvement supplement to the present application, the concentration of the printing liquid filled in the buffer cavity is higher than the concentration of the printing liquid contained in the printing pool. The printing liquid and buffer balls filled in the buffer cavity become the counterweight unit of the temperature detection unit. After the temperature detection unit is squeezed and damaged, the printing liquid and buffer balls filled in the buffer cavity will escape, and the overall density of the remaining part of the temperature detection unit will decrease. The remaining part of the temperature detection unit floats to the upper surface of the printing liquid contained in the printing pool, thereby protecting the temperature sensor group and preventing it from directly colliding with the stirring paddle due to the lack of buffer protection.

[0011] As a further improvement and supplement to the present application, a protective wall is fixedly connected to the side wall of the insulating pool body, and the inner wall at the corner of the protective wall is coated with a magnetic coating, wherein the protective wall plays a protective role, making it difficult for the temperature detection unit to quickly and directly contact the inner wall of the insulating pool body, thereby reducing the impact on the temperature detection unit. At the same time, the buffer ball leaked from the damaged temperature detection unit will contact the protective wall after falling and colliding with the stirring paddle. After colliding with the stirring paddle several times, it will stick to the corner of the protective wall, and the leaked buffer ball can be collected for easy recycling. At the same time, it also avoids frequent collisions between the buffer ball and the stirring paddle, which is not easy to cause damage to the stirring paddle.

[0012] As an improvement of the present application, the stirring paddle includes a paddle body, a shovel-shaped groove is bored on the paddle body, and the rotation direction of the stirring paddle is from the back side of the paddle body toward the shovel-shaped groove. The shovel-shaped groove facilitates the formation of an upward airflow, and the temperature detection unit that collides with the stirring paddle is also easy to move obliquely upward.

[0013] As another improvement of the present application, a fixed frame is fixedly connected to the opening of the printing and dyeing pool, and a plurality of insulation units that are staggered and overlapped with each other are fixedly connected to the inner wall of the fixed frame. The insulation units can form an insulation layer without affecting the movement of the materials to be printed and dyed, thereby reducing the heat dissipation of the printing and dyeing liquid and reducing the energy required to keep the printing and dyeing liquid warm.

[0014] As another improvement supplement of the present application, multiple insulation units protect the elastic fibers. The elastic fibers are hollow structures, and multiple capillary cracks are bored on the outer wall of the elastic fibers. While the insulation units have a heat-insulating effect, they also clean up excess printing and dyeing liquid on the surface of the printing and dyeing material, reduce the energy carried by the printing and dyeing liquid on the printing and dyeing material, and reduce the energy required for the printing and dyeing liquid to keep warm. At the same time, as the printing and dyeing liquid accumulates on the elastic fibers, its weight will increase until the original structural form of the elastic fibers is destroyed, and the printing and dyeing liquid drips from the elastic fibers, after which the elastic fibers resume their heat-insulating form.

[0015] In summary, during the rising and falling process of the temperature detection unit, the temperature sensor group will monitor the temperature of the printing and dyeing liquid. At the same time, at the moment of being knocked away by the stirring paddle, the movable piston and the temperature sensor group will produce relative displacement with the temperature detection unit under the action of inertia, and compress the integrated compression spring. After the temperature detection unit is knocked away, it will move back and forth under the joint action of the two compression springs, forming a water flow similar to animal breathing in the detection through hole, so that real-time water flow interaction can be achieved in different positions of the printing and dyeing pool in the detection through hole, thereby increasing the accuracy of the temperature sensor group detection, and can detect each position of the printing and dyeing liquid, so as to control the working status of the electric heating plate and the stirring paddle, and achieve energy saving effect.

[0016] At the same time, by processing the temperature sent back by the temperature sensor group, we reach the following: using time as the coordinate and the detected temperature as the ordinate to establish a rectangular coordinate system, and marking the standard temperature horizontal line of printing and dyeing in the above rectangular coordinate system, and entering the data detected by the temperature sensor group into the above rectangular coordinate system to form a smooth curve. The smooth curve and the standard temperature horizontal line will intersect with each other to form a closed space. The larger the above closed space, the greater the temperature difference of the printing and dyeing liquid, and the need to increase the rotation speed of the stirring paddle to speed up the heat exchange speed in the printing and dyeing liquid. When the smooth curve formed by the detection data of the temperature sensor group is mostly located on the upper side of the standard horizontal line, the temperature of most of the printing and dyeing liquid exceeds the standard temperature, and no heating work is required. The electric heating plate enters the standby state. On the contrary, when the smooth curve formed by the detection data of the temperature sensor group is mostly located on the lower side of the standard horizontal line, the temperature of most of the printing and dyeing liquid is lower than the standard temperature, and heating work is required. The electric heating plate needs to increase the power for heating so that the temperature of the printing and dyeing liquid rises to the set standard temperature.

[0017] By using the insulation unit, an insulation layer can be formed without affecting the movement of the materials to be printed and dyed, thereby reducing the heat dissipation of the printing and dyeing liquid and the energy required for keeping the printing and dyeing liquid warm. The excess printing and dyeing liquid on the surface of the materials to be printed and dyed can be cleaned up, reducing the energy carried by the printing and dyeing liquid on the materials to be printed and dyed, and reducing the energy required for keeping the printing and dyeing liquid warm.

DETAILED DESCRIPTION

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-2 and Figure 4-6 An energy-saving and environmentally friendly printing and dyeing processing equipment is shown, comprising a plurality of conduction rollers 1 matched with the positions of the printing and dyeing pool 3, a material to be printed and dyed 2 is wound on the conduction rollers 1, a printing and dyeing liquid 4 is contained in the printing and dyeing pool 3, and the material to be printed and dyed 2 is immersed in the printing and dyeing liquid 4 under the action of the plurality of conduction rollers 1, the printing and dyeing pool 3 comprises an insulating pool body 301, an electric heating plate 302 is fixedly connected to the bottom plate of the insulating pool body 301, a power end 5 is rotatably connected to the bottom plate of the printing and dyeing pool 3, a transmission shaft 6 is fixedly connected to the outer wall of the power end 5, and a plurality of stirring blades 7 are fixedly connected to the outer wall of the transmission shaft 6;

[0033] The printing and dyeing liquid 4 is mixed with a plurality of temperature detection units 9, and the plurality of temperature detection units 9 slowly fall in the printing and dyeing liquid 4. The temperature detection unit 9 includes an elastic shell 901, and a detection through hole 902 is drilled on the elastic shell 901. The openings at both ends of the detection through hole 902 are fixedly connected with limit rings 903 that match themselves. A movable piston 10 that matches itself is slidably connected in the detection through hole 902. A temperature sensor group 11 is fixedly connected in the movable piston 10. Compression springs 12 are fixedly connected between the two ends of the movable piston 10 and the two limit rings 903, respectively. A buffer cavity 904 is drilled in the elastic shell 901, and the buffer cavity 904 is filled with the printing and dyeing liquid 4. It is filled with multiple buffer balls 905, and the multiple buffer balls 905 are suspended in the printing and dyeing liquid 4 filled in the buffer cavity 904. In particular, a motor is provided at the lower end of the printing and dyeing pool 3, and the power output end of the motor passes through the bottom plate of the printing and dyeing pool 3, and is fixedly connected to the power end 5, so as to drive the power end 5, the transmission shaft 6 and the stirring paddle 7 to rotate. At the same time, a control terminal is also provided to control the working status of the conduction roller 1, the electric heating plate 302 and the motor, and to receive the detection data of the temperature sensor group 11. The setting and control of the motor are well-known technologies of technicians in this field, so they are not disclosed in detail in this application. Those skilled in the art can make reasonable settings based on the existing technology and meet the use requirements of this application.

[0034] In the present application, the electric heating plate 302 will heat the printing and dyeing liquid 4, and the presence of the stirring blade 7 will stir the printing and dyeing liquid 4 and form an upward flowing liquid, so as to uniformly heat the printing and dyeing liquid 4. The temperature detection unit 9 in the present application will slowly fall under the action of its own weight, and when the temperature detection unit 9 falls within the range of multiple stirring blades 7, the rotating stirring blades 7 will hit it and knock the temperature detection unit 9 upward again. In the process of the temperature detection unit 9 rising and falling, the temperature sensor group 11 will monitor the temperature of the printing and dyeing liquid 4. At the same time, at the moment of being knocked away by the stirring blade 7, the movable piston 10 and the temperature detection unit 9 will be moved upward again. Under the action of inertia, the temperature sensor group 11 will produce relative displacement with the temperature detection unit 9, forming pressure on the integrated compression spring 12. After the temperature detection unit 9 is knocked away, it will move back and forth under the joint action of the two compression springs 12, forming a water flow similar to animal breathing in the detection through hole 902, so that real-time water flow interaction can be achieved in different positions of the printing and dyeing pool 3 in the detection through hole 902, thereby increasing the detection accuracy of the temperature sensor group 11, and can detect various positions of the printing and dyeing liquid 4, so as to control the working status of the electric heating plate 302 and the stirring paddle 7, thereby achieving energy-saving effects.

[0035] During normal operation, the temperature sensor group 11 will transmit its own detection data back to the control terminal in real time, and the control terminal will perform data analysis: a rectangular coordinate system is established with time as the coordinate and the detection temperature as the vertical coordinate, and a standard temperature horizontal line for printing and dyeing is marked in the above rectangular coordinate system. The data detected by the temperature sensor group 11 is entered into the above rectangular coordinate system to form a smooth curve. The smooth curve and the standard temperature horizontal line will intersect with each other to form a closed space. The larger the above closed space, the greater the temperature difference of the printing and dyeing liquid 4, and the rotation speed of the stirring blade 7 needs to be increased. The heat exchange speed in the printing and dyeing liquid 4 is that when the smooth curve formed by the detection data of the temperature sensor group 11 is mostly located on the upper side of the standard horizontal line, the temperature of most of the printing and dyeing liquid 4 exceeds the standard temperature, and no heating work is needed. The electric heating plate 302 enters the standby state. On the contrary, when the smooth curve formed by the detection data of the temperature sensor group 11 is mostly located on the lower side of the standard horizontal line, the temperature of most of the printing and dyeing liquid 4 is lower than the standard temperature and heating work is required. The electric heating plate 302 needs to increase the power for heating so that the temperature of the printing and dyeing liquid 4 rises to the set standard temperature.

[0036] In the present application, by cooperating with the stirring paddle 7 and the temperature detection unit 9, on the one hand, the temperature of different positions of the printing and dyeing liquid 4 can be detected to increase the accuracy of temperature detection; on the other hand, the temperature inside the printing and dyeing liquid 4 can be judged through the detection data fed back by the temperature detection unit 9, thereby controlling the electric heating plate 302 and the stirring paddle 7 to achieve the best working state and reduce excessive energy loss.

[0037] The outer walls of multiple buffer balls 905 are coated with a magnetic coating of the same level, and the inner wall of the detection through hole 902 is fixedly connected with a reinforcing net 906. The existence of the reinforcing net 906 can increase the strength of the elastic shell 901, so that the elastic shell 901 is not easily damaged by the impact of the stirring paddle 7. After the temperature detection unit 9 is knocked away, under the action of the magnetic coating of the same level, the multiple buffer balls 905 will disperse from each other and restore the buffering effect. The concentration of the printing and dyeing liquid 4 filled in the buffer cavity 904 is higher than that of the printing and dyeing liquid 4 contained in the printing and dyeing pool 3. The printing and dyeing liquid 4 and the buffer balls 905 filled in the buffer cavity 904 become the counterweight unit of the temperature detection unit 9. After the temperature detection unit 9 is squeezed and damaged, the printing and dyeing liquid 4 and the buffer balls 905 filled in the buffer cavity 904 will escape, and the overall density of the remaining part of the temperature detection unit 9 will decrease. It floats to the upper surface of the printing and dyeing pool 3 containing the printing and dyeing liquid 4, thereby protecting the temperature sensor group 11 and preventing it from directly colliding with the stirring blade 7 due to the lack of buffer protection. A protective wall 8 is fixedly connected to the side wall of the insulating pool body 301, and the inner wall at the corner of the protective wall 8 is coated with a magnetic coating, wherein the protective wall 8 plays a protective role, making it difficult for the temperature detection unit 9 to quickly and directly contact the inner wall of the insulating pool body 301, thereby reducing the impact on the temperature detection unit 9. At the same time, the buffer ball 905 leaked from the damaged temperature detection unit 9 will contact the protective wall 8 after falling and colliding with the stirring blade 7. After colliding with the stirring blade 7 several times, it will stick to the corner of the protective wall 8, and the leaked buffer ball 905 will be collected for easy recycling. At the same time, it also avoids frequent collisions between the buffer ball 905 and the stirring blade 7, which is not easy to cause damage to the stirring blade 7.

[0038] See also Figure 3 The stirring blade 7 includes a blade body 701, on which a shovel-shaped groove 702 is cut. The rotation direction of the stirring blade 7 is from the back of the blade body 701 toward the shovel-shaped groove 702. The cutting of the shovel-shaped groove 702 facilitates the formation of an upward airflow, and the temperature detection unit 9 that collides with the stirring blade 7 is also easy to move obliquely upward.

[0039] The second implementation method:

[0040] Figure 7-10The invention shows an energy-saving and environmentally friendly printing and dyeing processing equipment, wherein a fixing frame 13 is fixedly connected to the opening of the printing and dyeing pool 3, and a plurality of mutually staggered overlapping insulation units 14 are fixedly connected to the inner wall of the fixing frame 13. The insulation units 14 can form an insulation layer without affecting the movement of the material 2 to be printed and dyed, thereby reducing the heat dissipation of the printing and dyeing liquid 4 and the energy required for heat preservation of the printing and dyeing liquid 4. The plurality of insulation units 14 all protect the elastic fiber 1401, which is a hollow structure, and a plurality of insulation units 14 are cut on the outer wall of the elastic fiber 1401. The capillary cracks 1402, while the insulation unit 14 has a heat-insulating effect, it also cleans the excess printing liquid 4 on the surface of the printing and dyeing material 2, reduces the energy carried by the printing liquid 4 on the printing and dyeing material 2, and reduces the energy required for the insulation of the printing liquid 4. At the same time, as the printing liquid 4 on the elastic fiber 1401 is enriched, its weight will also increase until the original structural form of the elastic fiber 1401 is destroyed, and the printing liquid 4 drips from the elastic fiber 1401, and then the elastic fiber 1401 returns to the insulation form.

[0041] Compared with the first embodiment, in this embodiment, the insulation unit 14 is used to form an insulation layer without affecting the movement of the material to be printed and dyed 2, thereby reducing the heat dissipation of the printing and dyeing liquid 4 and the energy required for keeping the printing and dyeing liquid 4 warm. The excess printing and dyeing liquid 4 on the surface of the material to be printed and dyed 2 can also be cleaned up to reduce the energy carried by the printing and dyeing liquid 4 contaminated on the material to be printed and dyed 2, and reduce the energy required for keeping the printing and dyeing liquid 4 warm.

[0042] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
