Description

Technical Field

[0001] The invention relates to the field of printing and dyeing equipment, in particular to an amplitude modulation device for an open-width soft finishing machine. Background Art

[0002] With the continuous development of social economy, people's requirements for the quality of life are also constantly improving, and the requirements for the texture, feel and comfort of the clothes they wear are also getting higher and higher, that is, the quality requirements for fabrics are getting higher and higher. During the processing of fabrics, they need to be treated with an open-width softening finishing machine to ensure the softness and fluffiness of the fabrics. Most open-width softening finishing machines use air jets to make the air jet hit the surface of the fabric, so that the treated fabric can be softer and fluffier, and the texture of the fabric is improved. However, the blowing direction of the air flow is relatively single, and it can only blow air on one side of the fabric, and the processing effect is poor. In addition, for some fabrics, dust will be adsorbed on the surface due to static electricity. If only one side is blown, the dust on the leeward side is difficult to be blown down. The blown dust is raised, and on the one hand, it is easy to be adsorbed on the fabric again, and on the other hand, it is scattered in the air and easily inhaled by the staff, affecting the physical and mental health of the staff. In addition, different fabrics have different widths, and the fabrics are conveyed by conveyor rollers. During the conveying process, there are no limit constraints on both sides of the fabric, and the fabric is easy to deviate left and right. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the air flow blowing direction is relatively single, and it can only blow air on one side of the fabric, resulting in poor treatment effect. In addition, for some fabrics, dust will be adsorbed on the surface due to static electricity. If air is blown on a single side, the dust on the leeward side is difficult to be blown off.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is: an amplitude modulation device for an open-width soft finishing machine, comprising a casing and two groups of conveying members symmetrically arranged inside the casing, the upper ends of both sides of the casing are open, each group of the conveying members is two conveying rollers and is distributed up and down, a transmission roller is provided for rotation inside the casing, a conveyor belt is provided on one side of the casing to cooperate with one of the open ends of the casing, the conveyor belt is used to convey fabrics, a winding roller is provided on the other side of the casing to cooperate with the other open end of the casing, the winding roller is used to wind up the fabric, the casing Motors for driving the conveyor belt and the winding roller are respectively provided on the outside, and a return tube is provided inside the casing. The fabric passes through the middle of the return tube and bypasses the upper end of the transmission roller. The return tube is composed of two blowing pipes and two connecting pipes that are interconnected. A plurality of air outlet holes are provided on opposite sides of the two blowing pipes, and the plurality of air outlets are distributed horizontally linearly. A fan is fixedly provided on the upper end of the casing, and the output end of the fan is connected to the inside of the connecting pipe through the air supply pipe. Wind shields are respectively provided at the two open ends of the casing, and an air circulation component is provided inside the casing.

[0005] The beneficial effects of the present invention are as follows: by setting a return tube, the effect of blowing air on both sides of the fabric is achieved. On the one hand, the swing amplitude of the fabric is increased, and the relatively generated high-speed airflow drives the fabric to move back and forth, so that the fabric achieves the effects of softening, fluffing, drying, shaking and pre-shrinking. On the other hand, it is convenient to blow on both sides of the fabric, so that the attached dust and impurities are blown away.

[0006] As a further improvement of the present invention, the technical problem to be solved is that it is difficult to discharge the blown dust.

[0007] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: the air circulation component includes a sleeve and two exhaust pipes, one end of the two exhaust pipes passes through the middle of the return pipe and the upper surface is linearly evenly provided with a plurality of first air inlet holes, the lower surface of the middle of the two exhaust pipes is linearly evenly provided with a plurality of second air inlet holes, the two exhaust pipes are respectively fixed with fixed pipes matching the sleeve on opposite sides, the two fixed pipes are dynamically sealed with the inner wall of the sleeve, the middle part of the upper end of the sleeve is connected to the fan input end through the suction pipe, the fan is provided with a filter matching the input end, and the other end of the two exhaust pipes is fixed with a rectangular block.

[0008] The beneficial effects of the above improvements are: by setting two exhaust pipes, an air suction pipe, and a first air inlet hole and a second air inlet hole, the effect of air circulation is achieved, and the first air inlet hole and the second air inlet hole are facing upward and downward respectively, which can effectively prevent the first air inlet hole and the second air inlet hole from adsorbing the fabric, and facilitate the suction and discharge of blown dust and impurities, and then the staff can disassemble and replace the filter.

[0009] As a further improvement of the present invention, the technical problem to be solved is: fabrics of different widths are easily deflected during conveyance, and it is difficult to prevent deflection of different fabrics.

[0010] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: one of the wind shields is a fixed baffle, and the fixed baffle is close to the side of the winding roller. The other wind shield consists of a fixed plate and an inspection door. The fixed plate is fixedly arranged on the top surface of the casing, and the inspection door is hinged to the lower end of the outer side of the fixed plate through a hinge. A slide groove is provided on the inner side of the fixed baffle to cooperate with the rectangular block, and a bidirectional screw rod is provided for rotation in the slide groove. The two rectangular blocks are threadedly connected to the bidirectional screw rod, and one end of the bidirectional screw rod passes through the outside of the casing. A motor for driving the bidirectional screw rod to rotate is provided on the outside of the casing, and one end of the two exhaust pipes is provided with a restraining part that cooperates with the inspection door.

[0011] The beneficial effects of the above improvements are: through the mutual cooperation of the bidirectional screw and the two rectangular blocks, it is convenient to adjust the distance between the two exhaust pipes, so that the two exhaust pipes are close to the two sides of the fabric. On the one hand, it is convenient to protect fabrics of different widths and avoid left and right deviation during fabric transportation. On the other hand, it ensures the suction effect of the two exhaust pipes, which facilitates the timely removal of dust particles on the fabric.

[0012] As a further improvement of the present invention, the technical problem to be solved is: it is difficult to limit the opening and closing of the inspection door.

[0013] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: the restraint part includes a fixed shell fixed at one end of the exhaust pipe and a restraint block slidably arranged inside the fixed shell, one end of the restraint block is connected to the inner wall of the fixed shell through a spring, and the other end of the restraint block is embedded with a ball bearing, and a restraint plate is provided on the inner side of the inspection door, and an H-shaped sliding cavity for the sliding of the fixed shell is opened in the middle of the restraint plate.

[0014] The beneficial effects of the above improvements are as follows: through the mutual cooperation between the fixed shell and the H-shaped sliding cavity, when the fixed shell is in the middle of the H-shaped sliding cavity, the opening limit of the inspection door is achieved, the stability of the closing of the inspection door is ensured, and the windproof effect is achieved; when the fixed shell is located at both ends of the H-shaped sliding cavity, the limit constraint on the opening of the inspection door is released, and the inspection door is further pushed outward under the action of the spring reset, and then the staff flips the inspection door open to facilitate inspection of the inside of the casing.

[0015] As a further improvement of the present invention, the technical problem to be solved is: the blowing angle of the blower is fixed, and the wind blown out is relatively stable, resulting in a poor effect of the air flow hitting the fabric.

[0016] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: the two connecting pipes are rotatably connected to the inner wall of the casing through a rotating shaft on opposite sides, one of the rotating shafts is a hollow rotating shaft and one end is connected to the inside of the connecting pipe, and the other end passes through the outside of the casing and is connected to the air supply pipe through a rotating joint. Two first protrusions are symmetrically provided on the outer surfaces of the two connecting pipes, and impellers are rotatably provided inside the two exhaust pipes. The rotating shafts of the impellers are also hollow rotating shafts and both ends pass through the outside of the exhaust pipes and are rotatably connected through sealed bearings. A spline shaft is provided between the two exhaust pipes, and the two ends of the spline shaft respectively pass through the middle of the hollow rotating shafts of the two impellers and are rotatably connected to the inner wall of the casing. Discs are provided on the fixed sleeves on both sides of the spline shaft, and the outer surface of the disc is provided with a second protrusion that cooperates with the first protrusion.

[0017] The beneficial effect of the above improvement is: through the mutual cooperation between the first protrusion and the second protrusion, when the second protrusion alternately contacts and squeezes the two first protrusions, the connecting tube produces reciprocating deflection, that is, the blowing angle of the two blowing pipes is changed, further improving the effect of the fabric being hit by the blowing, thereby making the fabric softer.

[0018] The technical solution adopted in the present invention is further improved as follows: a counterweight block is provided at the lower end of each of the two connecting pipes.

[0019] The beneficial effect of the above improvement is: under the action of the counterweight block, the two connecting pipes are in a vertical downward state. When the second protrusion is out of contact with the first protrusion, the connecting pipe is restored to its original state under the action of the counterweight block, preparing for the next cooperation between the second protrusion and the first protrusion.

[0020] As a further improvement of the present invention, the technical problem to be solved is: the reciprocating swing frequency of the blowing pipe is low.

[0021] In order to solve the above technical problem, the present invention further improves and adopts a technical solution as follows: the number of the second bumps is four and they are distributed in a ring array.

[0022] The beneficial effects of the above improvements are: by setting four second protrusions, the frequency of contact and extrusion between the second protrusions and the first protrusions is increased, that is, the swing frequency of the return tube is increased, and the blowing effect of the blowing tube on the fabric is improved, so that the fabric has a good texture and feels more fluffy.

[0023] The present invention further improves the technical solution adopted as follows: the upper end cover of the casing is provided with a protective cover, the upper end of the casing is symmetrically provided with two fixing blocks, and the protective cover is fixedly connected to the upper end surfaces of the two fixing blocks by bolts respectively.

[0024] The beneficial effects of the above improvements are: providing safety protection and improving the overall aesthetics of the finishing machine.

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention. Example 1

[0036] like Figure 1-9As shown, an amplitude modulation device for an open-width soft finishing machine includes a housing 1 and two groups of conveying members symmetrically arranged inside the housing 1. The upper ends of both sides of the housing 1 are open, and each group of conveying members is two conveying rollers 14 distributed up and down. A transmission roller 12 is provided for rotation inside the housing 1. A conveyor belt 2 is provided on one side of the housing 1 to match one of the open ends of the housing 1. The conveyor belt 2 is used to convey fabrics. A winding roller 15 is provided on the other side of the housing 1 to match the other open end of the housing 1. The winding roller 15 is used to wind up the fabric. The outer sides of the housing 1 are respectively provided with The motor that drives the conveyor belt 2 and the winding roller 15 is used to rotate. A return tube is provided inside the casing 1. The fabric passes through the middle of the return tube and bypasses the upper end of the transmission roller 12. The return tube is composed of two blowing tubes 8 and two connecting tubes 9 that are interconnected. The two blowing tubes 8 have multiple air outlets on opposite sides. The multiple air outlets are distributed horizontally and linearly. A fan 7 is fixed on the upper end of the casing 1. The output end of the fan 7 is connected to the inside of the connecting tube 9 through the air supply tube 10. Wind shields are provided at the two open ends of the casing 1. An air circulation component is provided inside the casing 1. By providing the return tube, the effect of blowing air on both sides of the fabric is achieved. On the one hand, the swing amplitude of the fabric is increased, and the relatively high-speed airflow generated drives the fabric to move back and forth, making the fabric soft, fluffy, dry, shaken, and pre-shrunk. On the other hand, it is convenient to blow on both sides of the fabric so that the attached dust and impurities are blown away.

[0037] The air circulation assembly includes a sleeve 20 and two exhaust pipes 19. One end of the two exhaust pipes 19 passes through the middle of the return pipe and has a plurality of first air inlet holes evenly distributed linearly on the upper surface. The lower surface of the middle of the two exhaust pipes 19 is evenly distributed linearly with a plurality of second air inlet holes. A fixed pipe 21 that cooperates with the sleeve 20 is fixed to the opposite side of the two exhaust pipes 19. The two fixed pipes 21 are dynamically sealed with the inner wall of the sleeve 20. The middle of the upper end of the sleeve 20 is connected to the input end of the fan 7 through the suction pipe 11. The fan 7 is provided with a filter that cooperates with the input end. A rectangular block 22 is fixed to the other end of the two exhaust pipes 19. By providing the two exhaust pipes 19, the suction pipe 11, and the first and second air inlet holes, the effect of air circulation is achieved. The first and second air inlet holes are oriented upward and downward, respectively, which can effectively prevent the first and second air inlet holes from adsorbing the fabric.

[0038] One of the windshields is a fixed baffle 13, located near the side of the winding roller 15. The other windshield consists of a fixed plate 3 and an inspection door 4. The fixed plate 3 is fixed to the top surface of the casing 1. The inspection door 4 is hinged to the lower end of the fixed plate 3 via a hinge. A sliding groove is provided on the inside of the fixed baffle 13, which cooperates with a rectangular block 22. A bidirectional screw is provided in the sliding groove for rotation. The two rectangular blocks 22 are threadedly connected to the bidirectional screw. One end of the bidirectional screw extends outside the casing 1. A motor is provided on the outside of the casing 1 for driving the bidirectional screw. One end of the two exhaust pipes 19 is provided with a restraint that cooperates with the inspection door 4. The interaction between the bidirectional screw and the two rectangular blocks 22 facilitates adjustment of the spacing between the two exhaust pipes 19, so that the two exhaust pipes 19 are close to both sides of the fabric. This not only facilitates protection of fabrics of different widths and prevents left and right deviation during fabric transportation, but also ensures the suction effect of the two exhaust pipes 19, so that dust particles on the fabric are promptly sucked away.

[0039] The restraining member includes a fixed housing 24 fixed to one end of the exhaust pipe 19 and a restraining block 27 slidably disposed within the fixed housing 24. One end of the restraining block 27 is connected to the inner wall of the fixed housing 24 via a spring 28, and the other end of the restraining block 27 is embedded with a ball bearing 29. A restraining plate 26 is provided on the inner side of the access door 4, and an H-shaped sliding cavity is defined in the middle of the restraining plate 26 for sliding the fixed housing 24. Through the interaction between the fixed housing 24 and the H-shaped sliding cavity, when the fixed housing 24 is in the middle of the H-shaped sliding cavity, the opening of the access door 4 is limited, ensuring the stability of the closed access door 4 and achieving a windproof effect. When the fixed housing 24 is located at both ends of the H-shaped sliding cavity, the restraint on the opening of the access door 4 is released. Further, under the return action of the spring 28, the access door 4 is pushed outward, and then the staff can flip the access door 4 open, facilitating maintenance inside the casing 1.

[0040] The two connecting pipes 9 are rotatably connected to the inner wall of the casing 1 on opposite sides through a rotating shaft, one of the rotating shafts is a hollow rotating shaft and one end is connected to the inside of the connecting pipe 9, and the other end passes through the outside of the casing 1 and is connected to the air supply pipe 10 through a rotary joint. Two first protrusions 17 are symmetrically provided on the outer surfaces of the two connecting pipes 9. Impellers 25 are rotatably provided inside the two exhaust pipes 19. The rotating shaft of the impeller 25 is also a hollow rotating shaft and both ends pass through the outside of the exhaust pipe 19 and are rotatably connected through sealed bearings. A spline shaft 23 is provided between the two exhaust pipes 19, and the two ends of the spline shaft 23 are respectively movable through the middle of the hollow rotating shafts of the two impellers 25 and are rotatably connected to the inner wall of the casing 1. Discs 16 are provided on fixed sleeves on both sides of the spline shaft 23, and the outer surface of the disc 16 is provided with a second protrusion 18 that cooperates with the first protrusion 17. Through the mutual cooperation between the first protrusion 17 and the second protrusion 18, when the second protrusion 18 alternately contacts and squeezes the two first protrusions 17, the connecting tube 9 produces reciprocating deflection, that is, the blowing angle of the two blowing tubes 8 is changed, further improving the effect of the fabric being hit by the blowing, thereby making the fabric softer.

[0041] The lower ends of the two connecting tubes 9 are provided with counterweights. Under the action of the counterweights, the two connecting tubes 9 are kept in a vertical downward position. When the second protrusion 18 is out of contact with the first protrusion 17, the counterweights restore the connecting tubes 9 to their original positions, preparing for the next engagement of the second protrusion 18 with the first protrusion 17.

[0042] There are four second protrusions 18 arranged in a circular array. The four second protrusions 18 increase the frequency of contact and compression between the second protrusions 18 and the first protrusions 17, thereby increasing the swing frequency of the circular tube and improving the blowing effect of the blowing tube 8 on the fabric, resulting in a better texture and a more fluffy feel to the fabric.

[0043] The upper end of the casing 1 is provided with a protective cover 5, and two fixing blocks 6 are symmetrically provided on the upper end of the casing 1. The protective cover 5 is fixedly connected to the upper end surfaces of the two fixing blocks 6 by bolts. It has a safety protection effect and can improve the overall aesthetics of the finishing machine.
