A flat-width continuous wet finishing machine for textiles

Abstract

This invention provides a flat-width continuous wet finishing machine for textiles, relating to the field of textile processing technology. It includes: a machine body with heating chambers on both the front and rear sides inside; and a connection opening on the top surface of the machine body corresponding to each of the two heating chambers. A main rotating block and a secondary rotating block are rotatably inserted into the two connection openings. This invention uses a motor-driven shaft to synchronously rotate the main and secondary rotating blocks, allowing the positions of a first temperature sensor and a second temperature sensor to be switched. This allows the first temperature sensor to be disconnected from the heating water to simulate a temperature drop, thereby simultaneously determining the operating status of the first temperature sensor and the first audible and visual alarm, ensuring they are always in normal working condition. This solves the problem of existing wet finishing machines lacking a fault self-checking mechanism for sensors and associated alarms, and being unable to perform self-checks on the operating status of sensors and associated alarms.

Description

Technical Field

[0001] This invention relates to the field of textile processing technology, and in particular to a flat-width continuous wet finishing machine for textiles. Background Technology

[0002] In the textile processing industry, wet finishing is a key step that determines the final quality of the product. It covers core processes such as desizing, scouring, bleaching, dyeing, and post-printing treatment. Its core principle is to achieve impurity removal, fiber modification, color adhesion, or functional finishing by fully contacting textiles with specific chemical solutions or hot water, ultimately endowing textiles with diverse properties such as softness, abrasion resistance, wrinkle resistance, and antibacterial properties.

[0003] The wet finishing process has extremely stringent requirements for water temperature. It is crucial to ensure the water temperature remains stable within the specified range; otherwise, the finishing effect will be compromised. Existing wet finishing machines generally use temperature sensors for water temperature monitoring. While this provides basic temperature control, the sensors are constantly immersed in high-temperature water. Under prolonged high-load, high-humidity conditions, if the sensor or its associated audible and visual alarm malfunctions (e.g., aging sensor wiring or a damaged alarm speaker), the equipment will be in a monitoring vacuum. Workers will be unable to detect abnormal water temperatures in time, potentially leading to the scrapping of batches of fabrics (e.g., excessively high water temperatures reduce fabric strength, or excessively low temperatures prevent dye fixation). Furthermore, existing equipment lacks a self-checking mechanism for sensors and alarms, making it impossible to self-check their operational status. Workers can only rely on visual observation and experience during routine inspections, making it difficult to identify potential faults in advance. This results in a persistent risk of equipment failure, failing to fundamentally guarantee the temperature stability and production safety of the wet finishing process. Summary of the Invention

[0004] This invention relates to a flat-width continuous wet finishing machine for textiles, which solves the problem that existing wet finishing machines lack a fault self-checking mechanism for sensors and associated alarms, and are unable to perform self-checking of the operating status of sensors and associated alarms.

[0005] This invention provides a flat-width continuous wet finishing machine for textiles, specifically comprising: a machine body; a wet finishing groove is formed on the top surface of the machine body; heating chambers are formed on both the front and rear sides of the machine body, and electric heating rods electrically connected to a control cabinet are installed inside each heating chamber; a row of through openings communicating with adjacent heating chambers are formed on the front and rear sides of the inner end of the wet finishing groove; an insertion opening is formed on the top surface of the machine body relative to each of the two heating chambers, communicating with them; two support baffles are fixedly installed symmetrically on the top surface of the machine body, and the two support baffles are connected by an axis. A rotating shaft is mounted on the control cabinet. A motor electrically connected to the control cabinet is mounted on the support baffle located on the front side, and the motor's shaft end is fixedly connected to the rotating shaft. A main rotating block and a secondary rotating block are fixedly mounted on the rotating shaft, and the main rotating block and the secondary rotating block are respectively rotatably inserted into two insertion openings. A first temperature sensing groove is opened at the bottom of the outer peripheral surface of the main rotating block, and a first temperature sensor electrically connected to the control cabinet is installed inside the first temperature sensing groove. A second temperature sensing groove is opened at the top of the outer peripheral surface of the secondary rotating block, and a second temperature sensor electrically connected to the control cabinet is installed inside the second temperature sensing groove.

[0006] Furthermore, a control housing is fixedly installed on the top surface of the support baffle located on the rear side. A pressing cavity is opened inside the control housing. An on / off switch electrically connected to the control cabinet is fixedly installed on the front side of the inner end of the pressing cavity. The on / off switch is a tactile switch.

[0007] Furthermore, a first audible and visual alarm and a second audible and visual alarm are respectively installed on the front and rear sides of the top of the machine body. Both the first and second audible and visual alarms are electrically connected to the control cabinet. When the on / off switch is in the unpressed start state, the second temperature sensor is in the dormant state. When the on / off switch is in the pressed start state, the on / off switch feeds a feedback signal to the control cabinet, and the control cabinet controls the second temperature sensor to start.

[0008] Furthermore, when the motor is not running, the first temperature sensing slot faces downwards and the second temperature sensing slot faces upwards, with the first temperature sensor immersed in the water in the heating chamber located at the front. When the control cabinet controls the motor shaft to rotate counterclockwise by 180 degrees, the first temperature sensing slot faces upwards and the second temperature sensing slot faces downwards, with the second temperature sensor immersed in the water in the heating chamber located at the rear.

[0009] Furthermore, a pressure plate is slidably inserted into the pressing cavity, and the rear end face of the pressure plate is fixedly connected to the rear side of the inner end of the pressing cavity by a reset spring; in the natural state of the reset spring, the front end face of the pressure plate is pressed against the button end of the on / off switch, and the on / off switch is in the pressed start state.

[0010] Furthermore, the front end face of the control housing has a communication hole that connects to the pressing chamber; a pressure column is fixedly installed on the front end face of the pressure plate, and the front end of the pressure column adopts a hemispherical structure; when the front end of the pressure column contacts the rear end face of the auxiliary rotating block, the front end face of the pressure plate contacts the button end of the on / off switch, but at this time the on / off switch is in the unpressed start state, and the reset spring is in the compressed state.

[0011] Furthermore, a mating slot is provided on the lower side of the rear end face of the sub-rotating block. The mating slot has an arc-shaped groove structure. When the second temperature sensing groove faces downward, the mating slot corresponds to the position of the connecting hole. At this time, the front end of the pressure column is inserted into the mating slot, and the front end of the pressure plate presses against the button end of the on / off switch, so that the on / off switch is in the pressed start state.

[0012] Furthermore, the left and right end faces of the machine body are each provided with a conveying opening that communicates with the wet finishing tank; the wet finishing tank is rotatably installed with two rows of conveying units, each row of conveying units consisting of evenly distributed auxiliary rollers.

[0013] This invention provides a flat-width continuous wet finishing machine for textiles, which has the following beneficial effects:

[0014] This invention heats the water in the wet finishing tank using an electric heating rod and combines it with a first temperature sensor to monitor the temperature in real time, ensuring that the water temperature remains stable within the required range and guaranteeing the quality of wet finishing of textiles. Furthermore, by alternately setting up auxiliary rollers in two rows of conveying units, the textiles are kept in an unfolded state in the wet finishing tank and are completely immersed in the heated water, ensuring uniform and thorough finishing and improving the wet finishing effect of textiles.

[0015] This invention uses a motor-driven shaft to synchronously rotate the main and auxiliary rotating blocks, allowing the positions of the first and second temperature sensors to be switched. This causes the first temperature sensor to detach from the heated water to simulate a temperature drop, thereby simultaneously determining the operating status of the first temperature sensor and the first audible and visual alarm, ensuring they are always in normal working condition. Based on the position switching of the first and second temperature sensors, the second temperature sensor is simultaneously activated and immersed in the heated water, temporarily taking over the temperature monitoring and alarm functions, avoiding monitoring gaps caused during the operation status determination process.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described 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.

[0030] Example: Please refer to Figures 1 to 8 :

[0031] This invention proposes a flat-width continuous wet finishing machine for textiles, comprising: a machine body 1, with a wet finishing trough 101 formed on the top surface of the machine body 1; conveying openings 102 connected to the wet finishing trough 101 on both the left and right ends of the machine body 1; two rows of conveying units are rotatably mounted inside the wet finishing trough 101, each row of conveying units consisting of evenly distributed auxiliary rollers 103; heating chambers 1012 are formed on both the front and rear sides inside the machine body 1, and electric heating rods 1013 electrically connected to the control cabinet are installed inside both heating chambers 1012; a row of through openings 104 connected to adjacent heating chambers 1012 are formed on the front and rear sides of the inner end of the wet finishing trough 101; and an insertion opening 1011 connected to the two heating chambers 1012 is formed on the top surface of the machine body 1 relative to the two heating chambers 1012. Two support baffles 105 are fixedly installed on the end face in a symmetrical manner. A rotating shaft 107 is mounted between the two support baffles 105 through a bearing. A motor 106 electrically connected to the control cabinet is installed on the support baffle 105 located on the front side. The rotating shaft end of the motor 106 is fixedly connected to the rotating shaft 107. A main rotating block 2 and a secondary rotating block 3 are fixedly installed on the rotating shaft 107. The main rotating block 2 and the secondary rotating block 3 are respectively rotatably inserted into two insertion openings 1011. A first temperature sensing groove 202 is opened at the bottom of the outer peripheral surface of the main rotating block 2. A first temperature sensor 201 electrically connected to the control cabinet is installed inside the first temperature sensing groove 202. A second temperature sensing groove 303 is opened at the top of the outer peripheral surface of the secondary rotating block 3. A second temperature sensor 302 electrically connected to the control cabinet is installed inside the second temperature sensing groove 303.

[0032] The control housing 108 is fixedly installed on the top surface of the support baffle 105 located on the rear side. A pressing chamber 1014 is provided inside the control housing 108. An on / off switch 1018, electrically connected to the control cabinet, is fixedly installed on the front side of the inner end of the pressing chamber 1014. The on / off switch 1018 is a touch switch. A first audible and visual alarm 109 and a second audible and visual alarm 1010 are respectively installed on the front and rear sides of the top of the unit 1. Both the first audible and visual alarm 109 and the second audible and visual alarm 1010 are electrically connected to the control cabinet. When the on / off switch 1018 is not pressed, the second temperature sensor 302 is in a dormant state. When the on / off switch 1018 is in the unpressed state, the second temperature sensor 302 is in a dormant state. When switch 1018 is in the pressed-on state, the feedback signal from switch 1018 is sent to the control cabinet, which controls the second temperature sensor 302 to start. When motor 106 is not started, the first temperature sensing slot 202 faces downward and the second temperature sensing slot 303 faces upward. The first temperature sensor 201 is immersed in the water in the heating chamber 1012 located on the front side. When the control cabinet controls the shaft end of motor 106 to rotate counterclockwise by 180 degrees, the first temperature sensing slot 202 faces upward and the second temperature sensing slot 303 faces downward. The second temperature sensor 302 is immersed in the water in the heating chamber 1012 located on the rear side.

[0033] A pressure plate 1016 is slidably inserted into the pressing cavity 1014. The rear end face of the pressure plate 1016 is fixedly connected to the rear side of the inner end of the pressing cavity 1014 by a return spring 1015. In the natural state, the front end face of the pressure plate 1016 is in contact with the button end of the on / off switch 1018, and the on / off switch 1018 is in the pressed-on state. A communication hole 1019 connected to the pressing cavity 1014 is provided on the front end face of the control housing 108. A pressure post 1017 is fixedly installed on the front end face of the pressure plate 1016. The front end of the pressure post 1017 adopts a hemispherical structure. When the front end of the pressure post 1017 is in contact with the rear end of the auxiliary rotating block 3... When the end faces are in contact, the front end face of the pressure plate 1016 contacts the button end of the on / off switch 1018, but at this time the on / off switch 1018 is in the unpressed start state, and the reset spring 1015 is in the compressed state. A mating slot 301 is provided on the lower side of the rear end face of the auxiliary rotating block 3. The mating slot 301 has an arc-shaped groove structure. When the second temperature sensing groove 303 faces downward, the mating slot 301 corresponds to the position of the connecting hole 1019. At this time, the front end of the pressure column 1017 is inserted into the mating slot 301, and the front end face of the pressure plate 1016 presses against the button end of the on / off switch 1018, and the on / off switch 1018 is in the pressed start state.

[0034] The working principle of this embodiment:

[0035] Water for wet finishing of textiles is added into the wet finishing tank 101. Since the two heating chambers 1012 are connected to the wet finishing tank 101 through the through opening 104, the water will enter the two heating chambers 1012 simultaneously.

[0036] After the water is added, the staff sets the heating temperature through the control cabinet and controls the electric heating rod 1013 to start, thereby heating the water in the wet finishing tank 101 to reach the temperature range required by the wet finishing process of textiles and to achieve long-term constant temperature control. When the water temperature rises to the specified temperature, the first temperature sensor 201 is started through the control cabinet and the monitoring threshold is set to monitor the water temperature in real time.

[0037] When the water temperature exceeds or falls below the set monitoring threshold, the first temperature sensor 201 sends a feedback signal to the control cabinet, which then activates the first audible and visual alarm 109 to promptly alert staff to intervene and maintain the equipment, thus preventing temperature fluctuations from affecting the wet finishing quality of textiles.

[0038] During wet finishing of textiles, one end of the textile first passes through the left conveying opening 102 and enters the wet finishing tank 101. Then, the auxiliary rollers 103, which form two rows of conveying units, are alternately placed up and down along the wet finishing tank 101. Finally, the textile extends out from the right conveying opening 102. At this time, the textile in the wet finishing tank 101 remains in an unfolded state and is completely immersed in heated water. The wet finishing process of the textile is then achieved by heating the water.

[0039] To ensure the temperature of the heated water, during inspections, staff can control the motor 106 to rotate 180 degrees counterclockwise via the control cabinet. At this time, the motor 106 drives the rotating shaft 107 to rotate, simultaneously driving the main rotating block 2 and the auxiliary rotating block 3 to rotate, so that the first temperature sensing slot 202 faces upward and the second temperature sensing slot 303 faces downward. The second temperature sensor 302 is immersed in the water in the heating chamber 1012 located at the rear. When the second temperature sensing slot 303 faces downward, the position of the mating slot 301 corresponds to the position of the connecting hole 1019. At this time, the front end of the pressure column 1017 is inserted into the mating slot 301, and the front end of the pressure plate 1016 will press against the button end of the on / off switch 1018. The on / off switch 1018 is in the pressed start state, which sends a feedback signal to the control cabinet, and the control cabinet controls the second temperature sensor 302 to start.

[0040] At this time, the first temperature sensor 201 is disconnected from the heating water. The temperature it monitors will inevitably be lower than the set monitoring threshold. If the first temperature sensor 201 is in a fault-free state, it will send a feedback signal to the control cabinet. The control cabinet will control the first audible and visual alarm 109 to start. If the first audible and visual alarm 109 is also in a fault-free state, the first audible and visual alarm 109 will start and generate an audible and visual alarm so that the current staff can judge the operating status of the first temperature sensor 201 and the first audible and visual alarm 109 to ensure that they can perform the due temperature monitoring and alarm functions.

[0041] Furthermore, since the second temperature sensor 302 is immersed in the heated water when it is in the start-up state, it can temporarily perform the corresponding temperature monitoring and alarm functions (the time period for judging whether the first temperature sensor 201 and the first audible and visual alarm 109 are in normal operation). When the water temperature exceeds or falls below the set monitoring threshold, the second temperature sensor 302 sends a feedback signal to the control cabinet, which then controls the second audible and visual alarm 1010 to start, promptly reminding staff to intervene for maintenance and avoiding the impact of temperature fluctuations on the wet finishing quality of textiles.

[0042] After the staff has determined the operating status of the first temperature sensor 201 and the first audible and visual alarm 109, they can control the motor 106 to rotate 180 degrees clockwise via the control cabinet. At this time, the motor 106 drives the rotating shaft 107 to rotate, synchronously driving the main rotating block 2 and the auxiliary rotating block 3 to rotate, so that the first temperature sensing slot 202 faces downward and the second temperature sensing slot 303 faces upward. The first temperature sensor 201 is immersed in the water in the heating chamber 1012 located at the front, and the first temperature sensor 201 resumes temperature monitoring. Function; when the second temperature sensing slot 303 faces upward, the position of the mating slot 301 and the connecting hole 1019 is offset, and the front end of the pressure column 1017 also disengages from the mating slot 301. At this time, under the pressure of the rear end of the auxiliary rotating block 3 against the front end of the pressure column 1017, the front end of the pressure plate 1016 no longer presses against the button end of the on / off switch 1018. Since the on / off switch 1018 is a tactile switch, the on / off switch 1018 automatically resets and closes at this time, thereby synchronously controlling the second temperature sensor 302 to re-enter the sleep state and avoid false alarms.
