Abstract

The present invention relates to the technical field of digital printing conveyor belts, and specifically to a high-strength digital printing special conveyor belt with a multi-layer structure. The present invention includes a support frame and a conveyor belt body, and a cloth is placed on the top of the conveyor belt body. The present invention is provided with an adsorption component, which first absorbs the floating hairs through an air pump and an air suction frame, and then sends them into the interior of a cyclone separator through a second air pipe.

Since some floating hairs and impurities are mixed in the airflow, they will enter the interior of the air pressure mechanism.

Description

Technical Field

[0001] The invention relates to the field of digital printing conveyor belts, in particular to a multi-layer high-strength conveyor belt dedicated to digital printing. Background Art

[0002] Conveyor belts specifically designed for digital printing are the core transport components of digital jet printing equipment. Traditional textile printing relies on rotary or flat screen printing, requiring conveyor belts to meet low-speed, intermittent transport requirements and are typically made of rubber or ordinary polyester. With the adoption of non-contact printing processes in digital printing, conveyor belts are required to provide continuous, high-precision, and highly stable fabric transport.

[0003] In the existing technology, the production process of fabrics inevitably produces impurities such as floating hair, thread ends and dust. When the fabric is transported through a conveyor belt, these impurities are very likely to adhere to the surface of the conveyor belt, forming a continuous source of pollution. Since the conveyor belt usually adopts a circular operation mode, the impurities remaining on the surface will be continuously transferred during repeated contact with the fabric, resulting in white spots, color spots and other defects in the printed area of the fabric, seriously affecting the appearance and pass rate of the finished product. At the same time, the floating hair carried by the fabric itself is easily affected by electrostatic adsorption during the transmission process. If the impurities on the conveyor belt surface are not cleaned in time, as the production time accumulates, the impurity layer will gradually thicken and form hard lumps, accelerating the wear of the conveyor belt surface and shortening its service life.

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention is provided with an adsorption component, which first absorbs the floating hair through the air pump and the suction frame, and then sends it into the interior of the cyclone separator through the second air pipe. Since the air flow speed entering the cyclone separator is relatively high, a spiral airflow will be formed inside the cyclone separator. The floating hair and impurities in the spiral airflow will gradually accumulate inside the cyclone separator due to pressure until they enter the interior of the collection frame.

When the gas inside the air storage bin is needed, the first motor will drive the drive rod and the double synchronous wheels to rotate, thereby driving the single synchronous wheel and the air blocking plate to perform circular motion through the synchronous belt. When the exhaust holes on the outer walls of the air blocking plate and the exhaust plate are aligned, the gas will be discharged on a large scale because it finds the exhaust end. In addition, the gas is continuously accumulated inside the mounting frame and is blocked by the sealing ring, which can increase the gas flow. The gas is discharged through the exhaust pipe and the air pressure plate. Since the cloth is located under the air pressure plate, the discharged gas pressure will be directly applied to the cloth, which can ensure its stability and the beauty of the printing when it is printed. After the gas cleans the surface of the cloth, it will enter the cyclone separator for processing, so that the gas will not be mixed with impurities. When it needs to be used, the gas will enter the gas storage bin for temporary storage. At this time, the gas will be used for the second time, so that the gas can exert pressure on the cloth, thereby increasing the stability of the printing process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] like Figures 1 to 9 As shown, a multi-layer high-strength conveyor belt specially used for digital printing includes a support frame 1 and a conveyor belt body 3. The cloth 2 is placed on the upper top of the conveyor belt body 3. The upper top of the support frame 1 is fixedly connected to the top frame 4. The upper top of the top frame 4 is provided with an adsorption component 6. The adsorption component 6 is used to absorb impurities on the surface of the cloth 2 and the conveyor belt body 3. The outer wall of the top frame 4 is provided with an air pressure mechanism 5 that discharges gas and applies pressure on the surface of the cloth 2. The interior of the support frame 1 is provided with a transmission mechanism 7 that drives the conveyor belt body 3 to work.

[0032] It should be noted that the adsorption component 6 can effectively absorb impurities on the surface of the cloth 2 and the conveyor belt body 3, ensuring that the surface of the cloth 2 is clean during the printing process, avoiding impurities from affecting the printing quality, and improving the printing yield rate. The air pressure mechanism 5 can discharge the gas and apply pressure on the surface of the cloth 2, so that the cloth 2 is more flat and fits during printing, enhancing the clarity and uniformity of the printed pattern. The transmission mechanism 7 is arranged inside the support frame 1, which can stably drive the conveyor belt body 3 to work, ensure the smoothness and continuity of the conveying process, and improve production efficiency. The adsorption component 6 and the air pressure mechanism 5 cooperate with each other, so that the gas discharged by the adsorption component 6 can be reused during use, so that the cloth 2 will be more stable during printing.

[0033] As a technical optimization solution of this embodiment, the adsorption component 6 includes an air pump 62 fixedly connected to the top of the top frame 4, and the top of the top frame 4 is fixedly connected to a cyclone separator 61 for spirally filtering impurities. The cyclone separator 61 is located on one side of the air pump 62. The outer wall of the top frame 4 is symmetrically fixedly connected to a fixed bracket 64 on the side away from the air pressure mechanism 5. The lower bottom ends of the two fixed brackets 64 are fixedly connected to a second electric push rod 641, and the telescopic end of the second electric push rod 641 is fixedly connected to a second limit frame 642. The ends of the two second limit frames 642 that are close to each other are damped and connected to an air suction frame 643 for absorbing gas, and the air suction frame 643 is inclined at forty degrees.

[0034] It should be noted that the air pump 62 cooperates with the cyclone separator 61 to efficiently suck impurities from the surface of the cloth 2 and the conveyor belt body 3, and spirally filters the impurities through the cyclone separator 61 to avoid the accumulation of impurities on the conveyor belt body 3, thereby ensuring the cleanliness of the printing operation environment. The combined design of the fixed bracket 64 and the second electric push rod 641 can flexibly adjust the height of the suction frame 643 to meet the adsorption requirements of cloth 2 of different thicknesses, and the pipe connected to the suction frame 643 can adopt a spring air pipe or a bellows. Since the suction frame 643 is inclined at forty degrees, the adsorption area can be increased. At the same time, the inclination angle is used to optimize the air flow direction and improve the impurity adsorption efficiency. The damping design of the suction frame 643 can be effectively adjusted quickly to ensure that its angle is always effective.

[0035] As a technical optimization solution of this embodiment, the adsorption component 6 also includes an air suction tee 644 fixedly connected to the end of the air suction frame 643, and the end of the air suction tee 644 away from the air suction frame 643 is fixedly connected to the suction end of the air pump 62, and the remaining two ends of the air suction tee 644 are connected to the air suction frame 643, and the two connecting points are respectively located at the two ends of one side of the air suction frame 643 close to the air pressure mechanism 5, the discharge end of the air pump 62 is fixedly connected to the second air pipe 63, and the other end of the second air pipe 63 is fixedly connected and connected to the access end of the cyclone separator 61, the upper top of the cyclone separator 61 is fixedly connected to the first air pipe 611, and the first air pipe 611 extends to the interior of the cyclone separator 61, and the lower bottom end of the cyclone separator 61 is connected to the collection frame 612 for storing impurities through flange bolts.

[0036] It should be noted that the suction tee 644 connects the suction frame 643 and the suction end of the air pump 62, so that the suction frame 643 can efficiently collect impurity gas and stably transport it to the air pump 62, ensuring the continuity and stability of impurity adsorption. The air pump 62 transports the gas to the cyclone separator 61 through the second air pipe 63. The cyclone separator 61 can efficiently separate impurities in the gas to prevent impurities from entering the working environment again, ensuring the continuous cleaning of the surface of the cloth 2 and the conveyor belt body 3. The first air pipe 611 is located inside the cyclone separator 61. The gas discharged from the air pump 62 is doped with impurities and can pass through the cyclone separation area. At this time, the airflow is separated from the impurities, and the impurities will enter the interior of the collection frame 612 below, while the airflow is discharged through the first air pipe 611.

[0037] As a technical optimization solution of this embodiment, the pneumatic mechanism 5 includes two mounting frames 51 symmetrically fixedly connected to the outer wall of the top frame 4, and the interior of the two mounting frames 51 is fixedly connected to a gas storage bin 52 for temporarily storing gas. The inner top of the top frame 4 is symmetrically fixedly connected to a first electric push rod 53, and the telescopic ends of the two first electric push rods 53 are fixedly connected to a first limit frame 531, and the opposite side of the two first limit frames 531 is fixedly connected to a pneumatic plate 532 for discharging gas.

[0038] It should be noted that the combination of the mounting frame 51 and the gas storage bin 52 provides a stable temporary storage space for the gas, ensuring the continuity of the air pressure operation, wherein the air pressure plate 532 can apply the gas evenly to the surface of the cloth 2, and during the printing process, it can fit more closely to the surface of the conveyor belt body 3, thereby enhancing the clarity and uniformity of the pattern after printing, and reducing the situation where the printing effect is poor due to the cloth 2 not fitting closely enough to the surface of the conveyor belt body 3.

[0039] As a technical optimization solution of this embodiment, the pneumatic mechanism 5 also includes a filter screen 54 fixedly connected to the inside of the air storage bin 52. The inside of the air storage bin 52 is fixedly connected with an exhaust plate 57 located below the filter screen 54. The lower bottom end of the exhaust plate 57 is rotatably connected with an air blocking plate 573. The lower top end of the exhaust plate 57 is fixedly connected with an air blocking ring 572. The air blocking ring 572 abuts against the outer wall of the air blocking plate 573. The outer wall of the blocking plate 573 is fixedly sleeved with a sealing ring 574 for sealing, and the sealing ring 574 is located inside the air blocking ring 572. The exhaust plate 57 and the air blocking plate 573 are sealed by the sealing ring 574.

[0040] It should be noted that the filter 54 can effectively filter the gas entering the gas storage tank 52, remove impurities, ensure the purity of the exhaust gas, and prevent impurities from escaping with the gas again, affecting the fabric 2 during printing. The impurities will adhere to the fabric 2 again, thereby affecting the quality of the fabric 2 after printing. The combined design of the air-blocking ring 572 and the sealing ring 574 enhances the sealing between the air-blocking plate 573 and the exhaust plate 57, prevents gas leakage, and ensures the stability of the air pressure output.

[0041] As a technical optimization solution for this embodiment, a protective frame 56 is fixedly connected to the opposite side of the outer wall of the two gas storage bins 52, and a first motor 55 is fixedly connected to the center of the upper top of the protective frame 56. The output end of the first motor 55 is fixedly connected to a driving rod 551, and the contact end of the driving rod 551 and the protective frame 56 is fixedly connected with a sealed bearing, and the driving rod 551 is rotatably connected to the protective frame 56 through the sealed bearing. The end of the driving rod 551 is located inside the protective frame 56 and is fixedly connected with a double synchronous wheel 552. The lower bottom ends of the two air blocking plates 573 are fixedly connected with a single synchronous wheel 553, and the outer walls of the two single synchronous wheels 553 and the double synchronous wheels 552 are connected with a synchronous belt 554 for transmission, and the two synchronous belts 554 are arranged up and down.

[0042] It should be noted that the first motor 55 cooperates with the drive rod 551 and the double synchronous wheels 552 to drive the two single synchronous wheels 553 to rotate synchronously through the synchronous belt 554, thereby realizing the synchronous opening and closing of the two air blocking plates 573, ensuring that the gas discharge volume of the two gas storage bins 52 is consistent, so that the cloth 2 is evenly stressed, and the sealed bearing ensures that the drive rod 551 rotates smoothly and is well sealed to prevent gas leakage and ensure the pressure stability inside the gas storage bin 52. At the same time, a corresponding one-way valve can be installed on the outer wall of the gas transmission tee 65, which is not shown in the figure, to avoid the backflow of gas entering the gas storage bin 52, causing the pressure inside the gas storage bin 52 to change, thereby affecting the pressure inside each gas storage bin 52 and causing uneven pressure.

[0043] As a technical optimization solution for this embodiment, the discharge ends of the two gas storage bins 52 are fixedly connected with exhaust pipes 533, and the end of the exhaust pipe 533 away from the gas storage bin 52 is fixedly connected to the air inlet end of the air pressure plate 532, and the air inlet ends of the two gas storage bins 52 are fixedly connected with the same gas supply tee 65, and the remaining end of the gas supply tee 65 is fixedly connected and communicated with the end of the first gas pipe 611, and the exhaust plate 57 and the upper top of the sealing ring 574 are penetrated by exhaust holes 571 for gas to pass through.

[0044] It should be noted that the exhaust pipe 533 connects the gas storage bin 52 with the air pressure plate 532, so that the treated gas in the gas storage bin 52 can be stably transported to the air pressure plate 532, ensuring the continuity of the air pressure output. The gas supply tee pipe 65 connects the first air pipe 611 of the cyclone separator 61 and the air inlet end of the gas storage bin 52, allowing the clean gas separated by the cyclone separator 61 to enter the gas storage bin 52, realizing gas recycling and improving resource utilization. The exhaust hole 571 cooperates with the sealing ring 574 to accurately control the gas discharge volume when the air blocking plate 573 rotates, ensuring stable air pressure output.

[0045] As a technical optimization solution of this embodiment, the transmission mechanism 7 includes a second motor 71 fixedly connected to the inner bottom end of the support frame 1, and the inner side wall of the support frame 1 is symmetrically rotatably sleeved with a driving roller 74, and the two are rotatably sleeved through bearings. The conveyor belt body 3 is sleeved on the outer walls of the two driving rollers 74, and the output end of the second motor 71 and the rotating shaft end of one of the driving rollers 74 are fixedly connected with a sprocket 72, and the outer walls of the two sprockets 72 are sleeved with chains 73.

[0046] It should be noted that when the output end of the second motor 71 is working, it can drive the chain 73 to work through the two sprockets 72, thereby achieving the purpose of driving the driving roller 74 to rotate, and further driving the conveyor belt body 3 to move, thereby cooperating with the fabric 2 to achieve printing on it.

[0047] As a technical optimization solution of this embodiment, the upper top of the support frame 1 is symmetrically fixedly connected with a bearing frame 77, and the inner rotating sleeve of the bearing frame 77 is provided with a cleaning roller 78. The cleaning roller 78 is used to apply rotational force to the conveyor belt body 3 and the surface of the cloth 2. The bearing frame 77 and the cleaning roller 78 are rotatably sleeved through bearings. The outer wall of the support frame 1 is fixedly connected with a third motor 76 at the position corresponding to the cleaning roller 78, and the output end of the third motor 76 is fixedly connected to the rotating shaft of the cleaning roller 78. The inner wall of the support frame 1 is fixedly connected with several T-shaped support steel frames 75, and the T-shaped support steel frames 75 are located at the interval between the two driving rollers 74.

[0048] It should be noted that the bearing frame 77 cooperates with the cleaning roller 78, and the cleaning roller 78 is driven to rotate by the third motor 76, applying a rotational cleaning force to the surface of the conveyor belt body 3 and the cloth 2, effectively removing surface impurities, ensuring the cleanliness of the material before printing, and improving the printing quality. The bearing connection ensures that the cleaning roller 78 rotates flexibly and stably, reducing operating noise and wear.

[0049] When the present invention is in use, the second motor 71 in the transmission mechanism 7 is started, and through the transmission of the sprocket 72 and the chain 73, one of the driving rollers 74 is driven to rotate. Since the conveyor belt body 3 is sleeved on the outer walls of the two driving rollers 74, the other driving roller 74 also rotates accordingly, thereby realizing the continuous operation of the conveyor belt body 3 and driving the cloth 2 to move. During the conveying process, the cleaning roller 78 is driven by the third motor 76 to rotate, applying a rotational force to the surface of the conveyor belt body 3 and the cloth 2, further removing impurities and dust that may remain on the surface, and ensuring that the surface of the cloth 2 is clean;

[0050] As impurities and dust are driven by the cleaning roller 78 and fly, the air pump 62 starts working to generate suction, and the suction frame 643 absorbs impurities such as floating hair on the surface of the cloth 2 and the conveyor belt body 3. Since the suction frame 643 is inclined at 40 degrees, it can more effectively cover a certain area and expand the suction range. The second electric push rod 641 can drive the second limiting frame 642 and the suction frame 643 to adjust their positions to adapt to different working scenarios and suction requirements. When the device conveys different cloths 2, due to the different thicknesses of different cloths 2, if the suction frame 643 is always in the same position, it is inevitable that the height will not allow it to effectively attract impurities. In this case, the second electric push rod 641 can drive the second limiting frame 642 and the suction frame 643 to move up and down. When impurities on the cloth 2 are caused to float due to fluctuations, the position of the suction frame 643 changes, so that the floating hair can be effectively absorbed for different cloths 2.

[0051] The absorbed floating hair and impurities are sent into the suction end of the air pump 62 through the air suction tee 644 along with the air flow, and are then transported to the inside of the cyclone separator 61 through the second air pipe 63 through the discharge end of the air pump 62. In the cyclone separator 61, due to the high speed of the incoming air flow, a spiral airflow is formed. According to the cyclone separation principle, the floating hair and impurities in the spiral airflow gradually move toward the inner wall of the cyclone separator 61 due to the centrifugal force, and continue to accumulate, and finally fall into the collection frame 612 under the action of gravity for collection, effectively removing the floating hair and other impurities on the surface of the cloth 2 and the conveyor belt body 3, providing a clean working environment for subsequent digital printing work, avoiding the influence of impurities on the printing quality, and ensuring the clarity and beauty of the printed pattern. At the same time, the spiral airflow can also collect the floating hair, realize the efficient collection of the floating hair, and prevent the floating hair from clogging the air supply tee 65.

[0052] The airflow passing through the cyclone separator 61 is separated to obtain a relatively pure airflow, which will enter the interior of the air storage bin 52 through the first air pipe 611 and the air supply tee pipe 65 for temporary storage. After the airflow collects impurities on the surface of the cloth 2, it will pass through the cyclone separator 61 for secondary utilization, and the secondary utilized airflow is stored in the air storage bin 52. During the temporary storage process, a small amount of floating hair and impurities in the airflow will be further blocked and intercepted by the filter 54, making the gas entering the air storage bin 52 purer. When the gas inside the air storage bin 52 needs to be used, the first motor 55 is started, driving the driving rod 551 and the double synchronous wheel 552 to rotate. The double synchronous wheel 552 drives the two single synchronous wheels 553 to rotate synchronously through the synchronous belt 554, thereby driving the air blocking plate 573 to perform a circular motion below the exhaust plate 57.

[0053] In the initial state, the sealing ring 574 on the air blocking plate 573 fits tightly with the air blocking ring 572, sealing the exhaust hole 571 to prevent the gas from being discharged. When the air blocking plate 573 rotates to a certain angle, the exhaust hole 571 on its outer wall is aligned with the exhaust hole 571 on the exhaust plate 57. At this time, the gas finds the discharge end (i.e., the exhaust hole 571). Since the gas has been continuously accumulated inside the gas storage bin 52 and the mounting frame 51, the gas pressure gradually increases under the blocking effect of the sealing ring 574. When the exhaust hole 571 is opened, the high-pressure gas is discharged on a large scale and enters the air inlet end of the air pressure plate 532 through the exhaust pipe 533. The air pressure plate 532 then discharges the gas. Since the cloth 2 is located below the air pressure plate 532, the pressure of the discharged high-pressure gas is directly applied to the cloth 2. During the digital printing process, the pressure generated by this high-pressure gas can ensure that the surface of the fabric 2 is flat and stable, and effectively prevent the fabric 2 from wrinkling, displacement and other problems, thereby ensuring the precise positioning and high-quality output of the printed pattern, greatly improving the aesthetics and yield of the printing. The discharge of the air pressure plate 532 is not continuous, and it will only be opened when the fabric 2 needs to be printed. Normally, the air blocking plate 573 and the exhaust holes 571 on the exhaust plate 57 are in a staggered state, and the flow of air is blocked by the air blocking plate 573. Part of the air flow may flow through the gap between the air blocking plate 573 and the exhaust plate 57. Under the influence of the sealing ring 574 and the air blocking ring 572, the leakage of the air flow can be further limited, so the purpose of gas storage can be achieved.
