Description

Technical Field

[0001] This invention relates to the field of conveyor belt production technology, specifically to a production equipment for a steel wire rope flame-retardant conveyor belt with a tightening function. Background Technology

[0002] As a key transportation component in industrial production, steel wire rope flame-retardant conveyor belts are widely used in various industries such as coal mines, ports, and power. Their production process involves several complex and critical steps, among which the calendering and winding steps directly affect the forming quality of the conveyor belt.

[0003] For example, patents "CN117601339A A Calendering Device for Conveyor Belt Production" and "CN213356377U A Winding Device for Industrial Conveyor Belt Production" disclose calendering and winding devices for conveyor belt production, respectively. Currently, traditional winding equipment usually adopts a fixed tension winding method. However, in actual operation, the winding diameter of the conveyor belt changes continuously during winding. Current winding equipment for conveyor belt production generally has difficulty in stably and dynamically controlling the tension of the conveyor belt, which easily leads to the winding effect not meeting expectations. In addition, in the calendering process, the cleanliness of the pressure rollers plays a decisive role in the surface flatness of the conveyor belt. Traditional conveyor belt production equipment mostly uses scrapers to clean the pressure rollers. However, this method is not only difficult to completely remove rubber residues, but also, during use, workers tend to make excessive contact between the scraper and the pressure roller in pursuit of better cleaning results. This operation method can easily cause scratches on the surface of the pressure rollers, affecting the normal operation of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a production equipment for flame-retardant steel wire rope conveyor belts with a tightening function, so as to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a production equipment for steel wire rope flame-retardant conveyor belts with a tightening function. The production equipment includes a calendering mechanism, a vulcanizing mechanism, and a winding mechanism. During operation, the calendering mechanism lays the upper and lower cover rubbers onto the belt core (the belt core is made of steel wire rope material). The calendered conveyor belt is then moved to the vulcanizing mechanism for shaping. Finally, the winding mechanism winds up the shaped conveyor belt. Compared to current conveyor belt production equipment, the present invention provides an adjustment mechanism on the side of the winding mechanism near the vulcanizing mechanism, and a detection mechanism below the winding mechanism. The detection mechanism is electrically connected to the adjustment mechanism. During operation, the detection mechanism detects the thickness of the conveyor belt wound on the winding mechanism in real time and transmits the information to the adjustment mechanism. The adjustment mechanism dynamically adjusts the tension of the conveyor belt to ensure that the tension of the conveyor belt remains stable during operation.

[0006] Furthermore, the calendering mechanism includes a machine body, a first pressure roller, and a second pressure roller. Two sets of the first pressure roller are respectively located at the upper and lower ends of the machine body. Two sets of the second pressure roller are also provided, with each set positioned between the two sets of first pressure rollers. During operation, the upper and lower cover rubber continuously wrap around the area where the belt core passes through the two sets of second pressure rollers (the calendering process of the upper and lower cover rubber and the belt core is existing technology, and its specific working principle will not be elaborated upon). Compared to current conveyor belt production devices, this invention provides a cleaning mechanism on the side of each set of second pressure rollers. This cleaning mechanism cleans the second pressure rollers, preventing pits or protrusions from appearing on the surface of the calendered conveyor belt and ensuring a smooth product surface.

[0007] Furthermore, the detection mechanism includes a mounting base and a detection plate. The mounting base is fixedly installed directly below the winding mechanism. The detection plate is movably mounted on the end of the mounting base near the winding mechanism via a sensing spring. A piezoelectric sheet is provided at the end of the detection plate near the sensing spring, and the end of the detection plate near the winding mechanism has an arc-shaped structure.

[0008] Furthermore, the adjustment mechanism includes a first adjustment roller, a second adjustment roller, and a support frame. The support frame is provided in two sets, each set of the support frame is provided with a slide groove and a lifting cylinder, and each set of the slide groove is provided with a movable seat. The first adjustment roller and the second adjustment roller are respectively located at the upper and lower ends between the two sets of movable seats, and each set of movable seats is connected to a set of lifting cylinders.

[0009] In operation, the shaped conveyor belt passes through the area between the first and second adjusting rollers and is then wound up by the winding mechanism. As the winding mechanism winds up the shaped conveyor belt, its diameter gradually increases. Since the detection plate is located directly below the winding mechanism, it gradually descends as the diameter increases. When the detection plate descends, the sensing spring compresses, causing the piezoelectric element to generate an electrical signal. The operator can determine the thickness of the conveyor belt on the winding mechanism by detecting this signal. In this invention, the piezoelectric element is connected to a lifting cylinder. The lifting cylinder dynamically drives a movable seat to move within a chute based on the electrical signal generated by the piezoelectric element. When the movable seat moves, the first and second adjusting rollers move synchronously. Through this technical solution, the present invention can dynamically adjust the tension of the conveyor belt according to its thickness on the winding mechanism, thereby ensuring that the tension of the conveyor belt remains stable during operation.

[0010] Furthermore, the detection mechanism also includes correction blocks, of which two sets are arranged opposite each other at both ends of the detection plate. A double-headed cylinder is installed inside the detection plate, and each set of correction blocks is connected to the double-headed cylinder via a connecting rod. When the conveyor belt is wound onto the winding mechanism, it first passes over the area above the detection plate. The two sets of correction blocks can correct the deviation of the conveyor belt to be wound, thus forcibly constraining it to always be in the center position of the winding mechanism, avoiding uneven edges. Finally, the distance between the two sets of correction blocks can be controlled by the double-headed cylinder, allowing the two sets of correction blocks to correct and constrain conveyor belts of different widths.

[0011] Furthermore, both the first and second adjusting rollers are electrostatic rollers. When the conveyor belt moves to the area between the first and second adjusting rollers, the surface of the conveyor belt can be cleaned by the first and second adjusting rollers to prevent dust and other impurities from being rolled into the bundled conveyor belt. The calendering mechanism is provided with a first guiding mechanism on the side near the vulcanizing mechanism, and a set of second guiding mechanisms are provided on both sides of the adjusting mechanism. The first and second guiding mechanisms enable the conveyor belt to enter and exit the vulcanizing mechanism horizontally, which facilitates the vulcanization and shaping of the conveyor belt.

[0012] Furthermore, the cleaning mechanism includes a fixed frame, with a first cavity at one end of the fixed frame near the second pressure roller and a second cavity at the other end of the fixed frame away from the second pressure roller. The lower ends of the first cavity and the second cavity are connected, and the upper end of the second cavity is connected to an external air intake system through a first air guide pipe. A first floating plate and a second floating plate are respectively provided at the upper and lower ends of the first cavity. The first floating plate is connected to the fixed frame through a first compression spring, and the second floating plate is connected to the fixed frame through a second compression spring. Both the first floating plate and the second floating plate are inclined and arranged in the first cavity.

[0013] Furthermore, the fixed frame is in contact with the second pressure roller at both ends near the machine body. The cleaning mechanism also includes an air jet plate and a cleaning cotton. The air jet plate is disposed between the first floating plate and the second floating plate. The air jet plate is connected to the external steam system through the second air guide pipe. There is a gap between the air jet plate and the second pressure roller. The cleaning cotton is disposed at the lower end of the fixed frame near the second pressure roller.

[0014] In this invention, when the second pressure roller rotates, the two ends of the fixed frame near the machine body are always in contact with the second pressure roller, and the first and second floating plates are also always in contact with the wall surface of the second pressure roller. Simultaneously, an external steam system continuously supplies high-pressure steam into the jet plate, while an external suction system continuously removes gas from the first and second cavities to ensure that the air pressure in the first and second cavities remains within a stable range. When the area of ​​the second pressure roller with rubber adhering to it comes into contact with the first floating plate, easily removable rubber is directly scraped off by the first floating plate and flows along the first floating plate to the bottom of the first cavity, while rubber that is difficult to remove passes through the first floating plate and continues to move to the jet plate. Nearby, high-pressure steam ejected by the jet plate can remove stubborn rubber from the second pressure roller. After cleaning, the second pressure roller continues to rotate, and a cleaning cotton is used to wipe it to prevent moisture from the high-pressure steam from adhering to the second pressure roller. Compared with the current method of directly cleaning the second pressure roller with a scraper, this invention ensures the cleaning effect and avoids excessive force applied by the scraper to the second pressure roller, which could cause scratches on the surface of the second pressure roller. Finally, the first and second floating plates in this invention also have a sealing function, which can reduce the leakage of high-pressure steam and facilitate subsequent recycling.

[0015] Furthermore, a filter assembly is provided at the middle position of the second cavity. The filter assembly includes a mounting frame with two sets of mounting holes. Each set of mounting holes contains a set of filter plates, and each set of filter plates contains a set of filter screens. When the cleaning mechanism of the present invention is working, the rubber residue that is cleaned will enter the filter screens in the filter plates along the airflow. The filter screens collect the rubber residue on the one hand, and prevent the airflow containing rubber residue from entering the external air intake system, thus affecting the subsequent high-pressure steam recovery and utilization.

[0016] Furthermore, a set of sliding plates is provided on both the upper and lower sides of the mounting frame, and a set of connecting frames is provided on each set of sliding plates. Two sets of partitions are provided at the end of the second cavity away from the first cavity. A set of magnetic blocks is provided on the side of each partition away from the second cavity, and each set of magnetic blocks is aligned with a set of connecting frames. The connecting frames are made of ferromagnetic material. When the cleaning mechanism of this invention is working, the two sets of sliding plates are located on the upper and lower sides of one set of filter plates, and the other set of filter plates is in working condition (i.e., the airflow containing rubber residue passes through this set of filter plates). When the operator needs to clean the filter plate in working condition... When cleaning the filter plate, simply moving two sets of magnetic blocks will cause the two sets of sliding plates to move synchronously. When the two sets of sliding plates move to the upper and lower sides of the filter plate to be cleaned, the filter plate to be cleaned will be separated from the second cavity. At this time, when the operator removes the filter plate to be cleaned from the mounting frame, it will not affect the normal flow of air in the second cavity (the airflow containing rubber residue will pass through the filter plate that is not aligned with the two sets of sliding plates). Through the above technical solution, the present invention can clean the filter assembly during operation, thereby ensuring the working effect of the filter assembly and the cleaning effect of the cleaning mechanism.

[0017] Compared with existing technologies, the advantages of this invention are as follows: Compared with current conveyor belt production equipment, this invention is equipped with an adjustment mechanism and a detection mechanism. Through the combination of a detection plate, a sensing spring, and a piezoelectric sheet, the thickness change of the conveyor belt during the winding process is monitored in real time and fed back to the adjustment mechanism. The adjustment mechanism dynamically changes the tension of the conveyor belt to ensure that the tension of the conveyor belt remains stable during operation, avoiding tension fluctuations caused by changes in the winding diameter in traditional conveyor belt production equipment, and preventing the conveyor belt from being too tight (easily deformed) or too loose (uneven winding). In this invention, the detection mechanism also has a correction and constraint function. When the conveyor belt is wound onto the winding mechanism, it first passes over the area above the detection plate. The two sets of correction blocks on the detection mechanism can correct the conveyor belt to be wound, forcibly constraining the conveyor belt to always be in the center position of the winding mechanism, avoiding the formation of uneven edges. In addition, the distance between the two sets of correction blocks can be controlled by a double-headed cylinder, so that the two sets of correction blocks are aligned. The positive block can correct and constrain conveyor belts of different widths. The invention also has a cleaning mechanism set on the side of the second pressure roller. The first floating plate scrapes away easily cleanable rubber residue, the air jet plate sprays high-pressure steam to soften stubborn residue, and the cleaning cotton wipes away residual moisture and small impurities. Compared with the current method of directly cleaning the second pressure roller by scraping, the invention can thoroughly remove rubber residue from the surface of the pressure roller, avoid the formation of pits or bumps on the surface of the conveyor belt during calendering, and ensure product flatness. On the other hand, the invention is gentler than traditional scrapers, avoiding the situation where workers make the scraper too close to the second pressure roller in order to improve the cleaning effect, so as to avoid scratching the surface of the second pressure roller. Finally, the invention also has a filter component, which prevents the rubber residue from clogging the external air intake system and ensures the stable operation of the cleaning mechanism. In addition, when cleaning the filter component, the filter screen inside the filter component can be replaced without stopping the machine, thereby significantly improving production efficiency.

[0029] 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.

[0030] Example: Figures 1-10 As shown, this invention provides a technical solution: a production equipment for a steel wire rope flame-retardant conveyor belt with a tightening function. The production equipment includes a calendering mechanism 1, a vulcanizing mechanism 3, and a winding mechanism 5. During operation, the calendering mechanism 1 lays the upper and lower cover rubber onto the belt core 2 (the belt core 2 is made of steel wire rope material). The calendered conveyor belt is then moved to the vulcanizing mechanism 3 for shaping. Finally, the winding mechanism 5 winds up the shaped conveyor belt. Compared to current conveyor belt production equipment, this invention has an adjusting mechanism 4 on the side of the winding mechanism 5 near the vulcanizing mechanism 3, and a detection mechanism 6 below the winding mechanism 5. The detection mechanism 6 is electrically connected to the adjusting mechanism 4. During operation, the detection mechanism 6 detects the thickness of the conveyor belt wound on the winding mechanism 5 in real time and transmits the information to the adjusting mechanism 4. The adjusting mechanism 4 dynamically adjusts the tension of the conveyor belt to ensure that the tension of the conveyor belt remains stable during operation.

[0031] like Figures 5-6 As shown, the calendering mechanism 1 includes a machine body 11, a first pressure roller 12, and a second pressure roller 13. Two sets of first pressure rollers 12 are provided, with each set positioned at the upper and lower ends of the machine body 11. Two sets of second pressure rollers 13 are also provided, positioned between the two sets of first pressure rollers 12. During operation, the upper and lower cover rubber continuously wrap around the area where the belt core 2 passes through the two sets of second pressure rollers 13 (the calendering process of the upper and lower cover rubber and the belt core 2 is existing technology; for specific working principles, please refer to patent CN104925575A2, "Canvas Core Conveyor Belt Production Device and Production Method"). Compared to current conveyor belt production devices, this invention provides a cleaning mechanism 14 on the side of each set of second pressure rollers 13. The cleaning mechanism 14 cleans the second pressure rollers 13, preventing pits or protrusions from appearing on the surface of the calendered conveyor belt and ensuring a smooth product surface.

[0032] like Figures 1-3 As shown, the detection mechanism 6 includes a mounting base 61 and a detection plate 62. The mounting base 61 is fixedly installed directly below the winding mechanism 5. The detection plate 62 is movably installed on the mounting base 61 near the winding mechanism 5 via a sensing spring. A piezoelectric sheet is provided at the end of the detection plate 62 near the sensing spring. The end of the detection plate 62 near the winding mechanism 5 has an arc-shaped structure.

[0033] like Figure 4 As shown, the adjustment mechanism 4 includes a first adjustment roller 41, a second adjustment roller 42, and a support frame 43. The support frame 43 is provided in two sets. Each set of support frames 43 is provided with a slide groove 431 and a lifting cylinder 44. Each set of slide grooves 431 is provided with a movable seat 45. The first adjustment roller 41 and the second adjustment roller 42 are respectively located at the upper and lower ends between the two sets of movable seats 45. Each set of movable seats 45 is connected to a set of lifting cylinders 44.

[0034] In operation, the shaped conveyor belt passes through the area between the first adjusting roller 41 and the second adjusting roller 42, and is then wound up by the winding mechanism 5. As the winding mechanism 5 winds up the shaped conveyor belt, its diameter increases. Since the detection plate 62 is located directly below the winding mechanism 5, it gradually descends as the diameter of the winding mechanism 5 increases. When the detection plate 62 descends, the sensing spring is compressed, causing the piezoelectric sheet to generate an electrical signal. The operator can determine the thickness of the conveyor belt on the winding mechanism 5 by detecting the electrical signal generated by the piezoelectric sheet. In this invention, the piezoelectric sheet is connected to the lifting cylinder 44. The lifting cylinder 44 can dynamically drive the movable seat 45 to move within the slide groove 431 based on the electrical signal generated by the piezoelectric sheet. When the movable seat 45 moves, the first adjusting roller 41 and the second adjusting roller 42 move synchronously. Through the above technical solution, this invention can dynamically adjust the tension of the conveyor belt according to the thickness of the conveyor belt on the winding mechanism 5, thereby ensuring that the tension of the conveyor belt remains stable during operation.

[0035] like Figures 2-3 As shown, the detection mechanism 6 also includes correction blocks 63. Two sets of correction blocks 63 are arranged opposite each other at both ends of the detection plate 62. A double-headed cylinder 621 is installed inside the detection plate 62. Each set of correction blocks 63 is connected to the double-headed cylinder 621 through a connecting rod 631. When the conveyor belt in this invention is wound onto the winding mechanism 5, it will first pass through the upper area of ​​the detection plate 62. The two sets of correction blocks 63 can correct the deviation of the conveyor belt to be wound, so as to force the conveyor belt to always be in the center position of the winding mechanism 5, avoiding the formation of uneven edges. Finally, this invention can also control the distance between the two sets of correction blocks 63 through the double-headed cylinder 621, so that the two sets of correction blocks 63 can correct and constrain conveyor belts of different widths.

[0036] like Figure 1 , Figure 4 As shown, both the first adjusting roller 41 and the second adjusting roller 42 are electrostatic rollers. When the conveyor belt moves to the area between the first adjusting roller 41 and the second adjusting roller 42, the surface of the conveyor belt can be cleaned by the first adjusting roller 41 and the second adjusting roller 42 to prevent dust and other impurities from being rolled into the bundled conveyor belt. The calendering mechanism 1 is provided with a first guiding mechanism on the side near the vulcanizing mechanism 3, and a set of second guiding mechanisms are provided on both sides of the adjusting mechanism 4. The first guiding mechanism and the second guiding mechanism enable the conveyor belt to enter and exit the vulcanizing mechanism 3 horizontally, which facilitates the vulcanization and shaping of the conveyor belt.

[0037] like Figure 1 , Figures 6-9As shown, the cleaning mechanism 14 includes a fixed frame 141. A first cavity is provided at the end of the fixed frame 141 near the second pressure roller 13, and a second cavity is provided at the end of the fixed frame 141 away from the second pressure roller 13. The lower end of the first cavity is connected to the lower end of the second cavity, and the upper end of the second cavity is connected to an external air intake system through a first air guide pipe 142. A first floating plate 1411 and a second floating plate 1413 are respectively provided at the upper and lower ends of the first cavity. The first floating plate 1411 is connected to the fixed frame 141 through a first compression spring, and the second floating plate 1413 is connected to the fixed frame 141 through a second compression spring. Both the first floating plate 1411 and the second floating plate 1413 are arranged in an inclined state in the first cavity.

[0038] like Figure 1 , Figures 6-9 As shown, the two ends of the fixed frame 141 near the machine body 11 are in contact with the second pressure roller 13. The cleaning mechanism 14 also includes an air jet plate 1412 and a cleaning cotton 144. The air jet plate 1412 is disposed between the first floating plate 1411 and the second floating plate 1413. The air jet plate 1412 is connected to the external steam system through the second air guide pipe 143. There is a gap between the air jet plate 1412 and the second pressure roller 13. The cleaning cotton 144 is disposed at the lower end of the fixed frame 141 near the second pressure roller 13.

[0039] In this invention, when the second pressure roller 13 rotates, the two ends of the fixing frame 141 near the machine body 11 are always in contact with the second pressure roller 13. The first floating plate 1411 and the second floating plate 1413 are also always in contact with the wall surface of the second pressure roller 13. At the same time, the external steam system continuously supplies high-pressure steam into the jet plate 1412, while the external suction system continuously sucks away the gas in the first cavity and the second cavity to ensure that the air pressure in the first cavity and the second cavity is maintained within a stable range. When the area on the second pressure roller 13 with rubber adhering to it comes into contact with the first floating plate 1411, the rubber that is easy to remove will be directly scraped off by the first floating plate 1411 and then flow along the first floating plate 1411 to the bottom of the first cavity, while the rubber that is not easy to remove will pass through the first floating plate 1411 and continue to move to the jet plate. Near 1412, high-pressure steam ejected by the jet plate 1412 can remove the rubber that is difficult to remove from the second pressure roller 13. After cleaning, the second pressure roller 13 continues to rotate, and the second pressure roller 13 is wiped with cleaning cotton 144 to prevent moisture contained in the high-pressure steam from adhering to the second pressure roller 13. Compared with the current method of directly cleaning the second pressure roller 13 with a scraper, the present invention ensures the cleaning effect and avoids excessive force applied by the scraper to the second pressure roller 13, which may cause scratches on the surface of the second pressure roller 13. Finally, the first floating plate 1411 and the second floating plate 1413 in the present invention also have a sealing function, which can reduce the leakage of high-pressure steam and facilitate subsequent recycling.

[0040] like Figure 1 , Figures 6-10 As shown, a filter assembly is provided in the middle of the second cavity. The filter assembly includes a mounting frame 1414 with two sets of mounting holes. Each set of mounting holes contains a set of filter plates 1417, and each set of filter plates 1417 contains a set of filter screens. When the cleaning mechanism 14 of the present invention is working, the rubber residue that is cleaned will enter the filter screen in the filter plate 1417 along the airflow. The filter screen collects the rubber residue on the one hand, and prevents the airflow containing rubber residue from entering the external air intake system, which would affect the subsequent high-pressure steam recovery and utilization.

[0041] like Figure 1 , Figures 6-10As shown, a set of sliding plates 14141 are provided on both the upper and lower sides of the mounting frame 1414. Each set of sliding plates 14141 is provided with a set of connecting frames 14142. Two sets of partitions 1415 are provided at the end of the second cavity away from the first cavity. A set of magnetic blocks 1416 are provided on the side of each partition 1415 away from the second cavity. Each set of magnetic blocks 1416 is aligned with a set of connecting frames 14142. The connecting frames 14142 are made of ferromagnetic material. When the cleaning mechanism 14 of the present invention is working, the two sets of sliding plates 14141 are located on the upper and lower sides of one set of filter plates 1417, and the other set of filter plates 1417 is in working state (i.e., the airflow containing rubber residue passes through this set of filter plates 1417). When the operator needs to clean the cleaning mechanism 14, the two sets of sliding plates 14141 are located on the upper and lower sides of one set of filter plates 1417. The other set of filter plates 1417 is in working state (i.e., the airflow containing rubber residue passes through this set of filter plates 1417). When cleaning the filter plate 1417 in operation, simply moving the two sets of magnetic blocks 1416 will cause the two sets of sliding plates 14141 to move synchronously. When the two sets of sliding plates 14141 move to the upper and lower sides of the filter plate 1417 to be cleaned, the filter plate 1417 to be cleaned will be separated from the second cavity. At this time, when the operator removes the filter plate 1417 to be cleaned from the mounting bracket 1414, it will not affect the normal flow of air in the second cavity (the airflow containing rubber residue will pass through the filter plate 1417 that is not aligned with the two sets of sliding plates 14141). Through the above technical solution, the present invention can clean the filter assembly during operation, thereby ensuring the working effect of the filter assembly and the cleaning effect of the cleaning mechanism 14.

[0042] The working principle of this invention is as follows: During operation, the core 2 is pressed into the upper and lower cover rubber by two sets of first pressure rollers 12 and two sets of second pressure rollers 13. When the second pressure rollers 13 rotate, they are cleaned by the first floating plate 1411 and the air jet plate 1412 to prevent pits or protrusions on the surface of the calendered conveyor belt, ensuring a smooth product surface. The vulcanizing mechanism 3 shapes the calendered conveyor belt, and finally, the winding mechanism 5 winds up the shaped conveyor belt. The invention utilizes the winding mechanism 5 as a lower... The device is equipped with a detection mechanism 6, which detects the thickness of the conveyor belt being wound on the winding mechanism 5 in real time and transmits the information to the adjustment mechanism 4. The adjustment mechanism 4 dynamically adjusts the tension of the conveyor belt to ensure that the tension of the conveyor belt remains stable during operation. In addition, when the conveyor belt to be wound moves above the detection mechanism 6, two sets of correction blocks 63 can correct the deviation of the conveyor belt to be wound, so as to force the conveyor belt to always be in the center position of the winding mechanism 5 and avoid the formation of uneven edges.

[0043] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
