Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and more specifically, to a flame-retardant solid woven conveyor belt core production and conveying device. Background Technology

[0002] The flame-retardant solid woven conveyor belt core production conveyor device is used in the production process of flame-retardant solid woven conveyor belts to continuously traction and convey the belt core through the impregnation station, ensuring that the flame-retardant fluid adheres to the surface of the belt core. As a key conveying link in the flame-retardant solid woven conveyor belt production line, this device mainly undertakes the task of conveying the belt core from unwinding to the coating process, ultimately enabling the finished belt core to acquire flame-retardant properties.

[0003] During transport, the heavy, integrally braided belt core has a significant weight and needs to be continuously pulled out from the unwinding drum by a front traction device. However, the large drum itself has considerable rotational inertia, which can easily create a dynamic response difference with the front traction speed, causing local tension fluctuations in the belt core during long-distance transport. When the traction force weakens instantaneously, the heavy belt core cannot maintain its tension due to its own weight, or the large drum may slack due to inertia as it continues to rotate. In this case, the slack belt core is prone to contact with related components, easily forming uneven wrinkles and folds on the belt core surface. When the belt core enters the subsequent flame-retardant fluid coating process, these wrinkles and folds will create coating blind spots, preventing the flame-retardant fluid from completely covering the belt core surface, resulting in uneven flame-retardant layer coating. This directly affects the integrity of the flame-retardant layer and the flame-retardant performance of the final product. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a flame-retardant solid woven conveyor belt core production and conveying device, so as to solve the problem that during the conveying process, the belt core becomes loose due to the asynchronous unwinding inertia force and traction force, which in turn leads to uneven coating of flame-retardant fluid and affects the flame-retardant performance of the product.

[0005] To solve the above problems, the present invention adopts the following technical solution: A flame-retardant solid woven conveyor belt core production conveying device includes an impregnation chamber, a front support platform fixedly installed at the front end of the impregnation chamber, a rear support platform fixedly installed at the rear end of the impregnation chamber, and a tensioning and retaining mechanism disposed at the rear end of the impregnation chamber. The tensioning and retaining mechanism includes two first support frames respectively fixedly connected to both sides of the rear surface of the impregnation chamber, a brake roller disposed between the rear ends of the two first support frames, a rotating shaft fixedly connected to one end of the brake roller, a plurality of flow-blocking blades fixedly connected to the surface of the rotating shaft, a water tank fixedly connected to the surface of the first support frames, the rotating shaft being rotatably inserted into the interior of the water tank, a water pump fixedly connected to the front surface of the water tank, the inlet of the water pump being connected to the lower end of the front surface of the water tank, the outlet of the water pump being connected to a water pipe, and the outlet of the water pipe being connected to the upper end of the front surface of the water tank.

[0006] Furthermore, a flow guide plate is fixedly connected inside the water tank, and the flow guide plate is located below multiple flow-blocking blades.

[0007] Furthermore, two guide plates are fixedly connected to the top of the rear surface of the first support frame, and a connecting block is slidably sleeved on the surface of the two guide plates. The rotating shaft is rotatably inserted into the interior of the connecting block. A first spring is fixedly connected to the lower surface of the connecting block. The bottom end of the first spring is fixedly connected to the top of the rear surface of the first support frame. A first support roller is rotatably connected between the rear ends of the two first support frames.

[0008] Furthermore, it also includes a flattening mechanism, which is located at the rear end of the impregnation chamber. The flattening mechanism includes two second support frames that are respectively fixedly connected to the rear ends of the two first support frames. The upper rear surface of each of the two second support frames is provided with a first support plate. The surfaces of the two first support plates are rotatably connected with spreading rollers. The two spreading rollers are arranged in a "V" shape. The ends of the two spreading rollers that are close to each other are fixedly connected with helical gears, and the two helical gears mesh with each other. The surface of one of the first support plates is fixedly connected with a first support plate, and the upper surface of the first support plate is fixedly connected with a first motor. The output shaft of the first motor is fixedly connected to the corresponding spreading roller.

[0009] Furthermore, two guide rods are fixedly connected to the lower surface of the first support plate, and a connecting seat is fixedly connected to the upper rear surface of the second support frame. The upper surface of the connecting seat is fixedly connected to the bottom ends of the two guide rods.

[0010] Furthermore, a second spring is fixedly connected to the bottom end of the first support plate, and the bottom end of the second spring is fixedly connected to the upper surface of the connecting seat.

[0011] Furthermore, a connecting crossbar is fixedly connected between the two first support plates.

[0012] Furthermore, it also includes an output traction mechanism, which is disposed at the front end of the impregnation chamber. The output traction mechanism includes two third support frames respectively fixedly connected to both sides of the front surface of the impregnation chamber. A first transmission roller is rotatably connected between the front ends of the two third support frames. A fourth support frame is fixedly connected to the front ends of the two third support frames. A second transmission roller is rotatably connected between the rear ends of the two fourth support frames. The first transmission roller and the second transmission roller are connected by a traction conveyor belt. The traction conveyor belt has a structure with protruding edges and a concave center. Multiple separating rubber strips are fixedly connected to the surface of the traction conveyor belt, which can divide the surface of the traction conveyor belt into multiple independent spaces.

[0013] Furthermore, a second support roller is rotatably connected between the front ends of the two third support frames, a second support plate is fixedly connected to the front end of the third support frame, a second motor is fixedly connected to the upper surface of the second support plate, and the output shaft of the second motor is fixedly connected to the first transmission roller.

[0014] Furthermore, the side of the traction conveyor belt is connected to multiple air pipes, which are respectively connected to multiple independent spaces separated by multiple rubber strips. The surface of each air pipe is connected to an air nozzle, and the interior of each air nozzle is slidably connected to a first baffle block and a second baffle block. The thin-walled ends of the first baffle block and the second baffle block are each provided with an air hole. The interior of each air nozzle is fixedly connected to two second support plates, and the surfaces of the two second support plates are fixedly connected to third springs. The ends of the two third springs that are close to each other are respectively fixedly connected to the surfaces of the first baffle block and the second baffle block. The upper and lower ends of the interior of each air nozzle are fixedly connected to limiting blocks that cooperate with the first baffle block and the second baffle block.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) When the traction of the belt core stops or the traction speed slows down, the water pump draws water into the water pipe and discharges it to the surface of the flow-blocking blades located below. The water flow impacts the flow-blocking blades and applies a thrust in the opposite direction to the flow-blocking blades and the brake roller. The brake roller pulls the belt core in the opposite direction, keeping the front section of the belt core in a taut state. Through the intervention of hydraulic damping, the rotational inertia generated by the large drum at the moment of traction deceleration is effectively absorbed, and the tension peaks and troughs of the belt core during long-distance transportation are smoothed out, ensuring that the belt core enters the impregnation chamber with constant tension, and avoiding the loosening and deformation of the belt core structure caused by sudden changes in local stress.

[0016] (2) In this scheme, the first motor drives the spreading roller to rotate. When the two spreading rollers rotate, they apply a force to the belt core that tilts to both sides. When the folds and wrinkles on the belt core pass under the two spreading rollers, the spreading rollers flatten the belt core, thus straightening the belt core before impregnation, eliminating the interlayer overlap caused by winding and self-weight sagging, and improving the permeability and coating uniformity of the flame retardant fluid in the fiber pores of the belt core.

[0017] (3) When the traction conveyor belt presses on the surface of the belt core, the traction conveyor belt and the separating rubber strip deform. The separating rubber strip squeezes out the air in the independent space that is separated in the traction conveyor belt and contacts the belt core, so that the independent space that contacts the belt core is adsorbed on the surface of the belt core. When the traction conveyor belt moves the belt core, it prevents the belt core from slipping and thus cannot be pulled normally. It also avoids the belt core from staying in the impregnation chamber for a long time, affecting the coating thickness of the flame retardant fluid, thereby ensuring the product quality of the belt core.

[0018] (4) When the independent space on the traction conveyor belt detaches from the core surface, the second baffle block moves away from the first baffle block, the two vents are connected, and external air enters the corresponding independent space on the traction conveyor belt, so that the core of the corresponding part quickly detaches from the traction conveyor belt, preventing the core from being torn due to excessive adhesion.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5A flame-retardant solid woven conveyor belt core production conveying device includes an impregnation chamber 2. A front support platform 1 is fixedly installed at the front end of the impregnation chamber 2, and a rear support platform 3 is fixedly installed at the rear end of the impregnation chamber 2. It also includes a tensioning and retaining mechanism located at the rear end of the impregnation chamber 2. The tensioning and retaining mechanism includes two first support frames 402 respectively fixedly connected to both sides of the rear surface of the impregnation chamber 2. A brake roller 401 is disposed between the rear ends of the two first support frames 402. A rotating shaft 405 is fixedly connected to one end of the brake roller 401, and a surface of the rotating shaft 405 is fixedly connected to... Multiple flow-blocking blades 406 are provided. A water tank 404 is fixedly connected to the surface of the first support frame 402. A rotating shaft 405 is rotatably inserted into the interior of the water tank 404. A water pump 408 is fixedly connected to the front surface of the water tank 404. The inlet of the water pump 408 is connected to the lower end of the front surface of the water tank 404. The outlet of the water pump 408 is connected to a water pipe 407. The outlet of the water pipe 407 is connected to the upper end of the front surface of the water tank 404. A guide plate 409 is fixedly connected inside the water tank 404. The guide plate 409 is located below the multiple flow-blocking blades 406.

[0023] Two guide plates 410 are fixedly connected to the top of the rear surface of the first support frame 402. A connecting block 411 is slidably sleeved on the surface of the two guide plates 410. The rotating shaft 405 is rotatably inserted into the interior of the connecting block 411. A first spring 412 is fixedly connected to the lower surface of the connecting block 411. The bottom end of the first spring 412 is fixedly connected to the top of the rear surface of the first support frame 402. A first support roller 403 is rotatably connected between the rear ends of the two first support frames 402.

[0024] By adopting the above technical solution, during the movement of the belt core, the belt core is located between the brake roller 401 and the first support roller 403. The first spring 412, which is in a stretched state, applies a downward pulling force, causing the brake roller 401 to press against the surface of the belt core. During the movement of the belt core, the belt core will drive the brake roller 401 to rotate together, thereby driving the flow-blocking blade 406 to rotate. When the traction of the belt core stops or the traction speed slows down, since the water tank 404 stores water, and the water pump 408 draws water into the water pipe 407 and discharges it to the surface of the flow-blocking blade 406 located below, the water flow can impact the flow-blocking blade 406, applying a thrust in the opposite direction to the flow-blocking blade 406 and the brake roller 401. Since the brake roller 401 presses against the surface of the belt core, it can pull the belt core in the opposite direction. Thus, when the traction of the belt core stops, the unfolded front section of the belt core remains taut, preventing the belt core from becoming loose and causing wrinkles and folds that form coating blind areas, thereby causing uneven coating of the flame-retardant fluid and affecting the flame-retardant performance of the product.

[0025] like Figure 6 and Figure 7As shown, it also includes a flattening mechanism, which is located at the rear end of the impregnation chamber 2. The flattening mechanism includes two second support frames 502 that are respectively fixedly connected to the rear ends of the two first support frames 402. The upper rear end surfaces of the two second support frames 502 are each provided with a first support plate 506. The surfaces of the two first support plates 506 are rotatably connected with a spreading roller 501. The two spreading rollers 501 are arranged in a "V" shape. The ends of the two spreading rollers 501 that are close to each other are fixedly connected with a helical gear 510. The two helical gears 510 mesh with each other. The surface of one of the first support plates 506 is fixedly connected with a first support plate 504. The upper surface of the first support plate 504 is fixedly connected with a first motor 503. The output shaft of the first motor 503 is fixedly connected to the corresponding spreading roller 501.

[0026] Two guide rods 507 are fixedly connected to the lower surface of the first support plate 506. A connecting seat 509 is fixedly connected to the upper rear surface of the second support frame 502. The upper surface of the connecting seat 509 is fixedly connected to the bottom ends of the two guide rods 507. A second spring 508 is fixedly connected to the bottom end of the first support plate 506. The bottom end of the second spring 508 is fixedly connected to the upper surface of the connecting seat 509. A connecting crossbar 505 is fixedly connected between the two first support plates 506.

[0027] By adopting the above technical solution, when the strip core is stretched and unfolded, the second spring 508 in a stretched state can press the spreading roller 501 downward onto the surface of the strip core. At the same time, when the strip core is stretched, the first motor 503 drives one of the spreading rollers 501 to rotate, and the other spreading roller 501 is driven to rotate through the cooperation of the helical gear 510. Since the two spreading rollers 501 are arranged in a "V" shape, the two spreading rollers 501 can apply a force that tilts to both sides to the strip core when they rotate. When the folds and wrinkles on the strip core pass under the two spreading rollers 501, the spreading rollers 501 can smooth out the strip core, thereby reducing the folds and wrinkles on the surface of the strip core and preventing the folds and wrinkles from forming coating blind spots, which would lead to uneven coating of the flame retardant fluid and affect the flame retardant performance of the product.

[0028] like Figures 8-11As shown, it also includes an output traction mechanism, which is located at the front end of the impregnation chamber 2. The output traction mechanism includes two third support frames 602 fixedly connected to both sides of the front surface of the impregnation chamber 2. A first transmission roller 606 is rotatably connected between the front ends of the two third support frames 602. A fourth support frame 605 is fixedly connected to the front ends of each of the two third support frames 602. A second transmission roller 608 is rotatably connected between the rear ends of the two fourth support frames 605. The first transmission roller 606 and the second transmission roller 608 are connected by a traction conveyor belt 601. The traction conveyor belt 601 has a structure with protruding edges and a concave center. Multiple separating rubber strips 609 are fixedly connected to the surface of the traction conveyor belt 601. The multiple separating rubber strips 609 can divide the surface of the traction conveyor belt 601 into multiple independent spaces. A second support roller 607 is rotatably connected between the front ends of the two third support frames 602. A second support plate 603 is fixedly connected to the front end of the third support frame 602. A second motor 604 is fixedly connected to the upper surface of the second support plate 603. The output shaft of the second motor 604 is fixedly connected to the first transmission roller 606.

[0029] The traction conveyor belt 601 has multiple air pipes 611 connected to its side. Each air pipe 611 is connected to multiple independent spaces separated by multiple rubber separators 609. Each air pipe 611 has an air nozzle 610 connected to its surface. The air nozzle 610 has a first baffle block 614 and a second baffle block 617 slidably connected inside. Both the first baffle block 614 and the second baffle block 617 have air holes 616 at their thin-walled ends. The air nozzle 610 has two second support plates 612 fixedly connected inside. Each of the two second support plates 612 has a third spring 613 fixedly connected to its surface. The ends of the two third springs 613 that are close to each other are fixedly connected to the surfaces of the first baffle block 614 and the second baffle block 617, respectively. The upper and lower ends of the air nozzle 610 have limiting blocks 615 that cooperate with the first baffle block 614 and the second baffle block 617 fixedly connected inside.

[0030] By adopting the above technical solution, when the belt core is pulled, since the belt core is located between the second support roller 607 and the traction conveyor belt 601, and the traction conveyor belt 601 is pressed on the surface of the belt core, the second motor 604 can provide power to drive the first transmission roller 606 and the second transmission roller 608 to rotate, thereby driving the traction conveyor belt 601 to run. The movement and traction of the belt core can be achieved by the friction between the traction conveyor belt 601 and the belt core.

[0031] When the traction conveyor belt 601 contacts the core surface, it presses against the core surface. At this time, the traction conveyor belt 601 and the separating rubber strip 609 deform, and the air in the independent space is squeezed out to the vent 610. The air pressure inside the vent 610 increases, the first baffle block 614 moves to the right, and the two vent holes 616 are connected. After the air is discharged, the corresponding third spring 613 pushes the first baffle block 614 to contact the limiting block 615 and merges with the second baffle block 617. The independent space in contact with the core is adsorbed onto the core surface. This prevents the core from slipping when the traction conveyor belt 601 moves the core, which would prevent the core from being pulled normally and remain in the impregnation chamber 2 for a long time, affecting the coating thickness of the flame retardant fluid and thus affecting the product quality of the core.

[0032] When the end of the traction conveyor belt 601 is rotated by the drive roller, the independent space adsorbed on it is forced to be pulled away from the surface of the belt core. The volume inside the independent space expands instantaneously, causing the internal air pressure to drop sharply and forming a negative pressure difference with the external ambient air pressure. The gas suction force generated by this negative pressure difference acts directly on the second baffle block 617 through the vent pipe 611. When the stiffness of the third spring 613 is configured to be more than the initial elastic resistance provided by the third spring 613, the second baffle block 617 will overcome the elastic force and slide inward and away from the first baffle block 614. At this time, the two vent holes 616 are connected again, and the external air is quickly backflowed in. The external air enters the corresponding independent space on the traction conveyor belt 601, which can cause the belt core of the corresponding part to detach from the traction conveyor belt 601.

[0033] Usage: The belt core is located between the brake roller 401 and the first support roller 403. The first spring 412, which is in a stretched state, applies a downward pulling force, causing the brake roller 401 to press against the surface of the belt core. When the belt core moves, it drives the brake roller 401 and the flow-blocking blade 406 to rotate together; When the traction of the belt core stops or the traction speed decreases, the water pump 408 discharges the water in the water tank 404 through the water pipe 407 and impacts the lower flow-blocking blade 406, applying a thrust in the opposite direction to the flow-blocking blade 406 and the brake roller 401, causing the brake roller 401 to pull the belt core in the opposite direction, keeping the unfolded front section of the belt core in a taut state. During traction and unfolding, the second spring 508, which is in a stretched state, causes the spreading roller 501 to press downwards onto the surface of the belt core. The first motor 503 drives one of the spreading rollers 501 to rotate, and through the cooperation of the helical gear 510, it drives the other spreading roller 501 to rotate. The two spreading rollers 501 are arranged in a "V" shape. When rotating, they apply a force to tilt to both sides to the belt core, smoothing out the folds and wrinkles on the surface of the belt core. The belt core is located between the second support roller 607 and the traction conveyor belt 601, with the traction conveyor belt 601 pressing against the surface of the belt core. The second motor 604 drives the first transmission roller 606 and the second transmission roller 608 to rotate, which in turn drives the traction conveyor belt 601 to run, and uses the friction between the traction conveyor belt 601 and the belt core to pull the belt core to move. When the traction conveyor belt 601 presses against the belt core surface, the separating rubber strip 609 deforms, squeezing the air in the independent space in contact with the belt core into the vent 610. The air pressure inside the vent 610 increases, causing the first baffle block 614 to move, and the two vent holes 616 connect to discharge the air. After the air is discharged, the corresponding third spring 613 pushes the first baffle block 614 to contact the limiting block 615 and merge with the second baffle block 617, so that the independent space is adsorbed on the surface of the belt core to prevent the belt core from slipping. When the independent space on the traction conveyor belt 601 is separated from the belt core surface by the transmission, the resulting separation force is greater than the elastic resistance of the third spring 613 connected to the second baffle block 617. The second baffle block 617 moves away from the first baffle block 614, and the two vents 616 are connected again, allowing external air to enter the independent space, causing the belt core at the corresponding part to separate from the traction conveyor belt 601.
