Description

Technical Field

[0001] This application relates to the field of belt cleaning equipment technology, and specifically to a belt cleaning device. Background Technology

[0002] Currently, in the automated manufacturing process of automobiles, sheet metal transportation is generally completed through sheet metal conveyor belts. In order to adapt to the flexible production of multiple models, the production line design needs to meet the requirements of mixed steel and aluminum production. In order to adapt to the simultaneous transportation of high-frequency steel and aluminum sheets, the sheet metal conveyor belt is designed to be a conveyor belt with both magnetic and high friction. The magnetic conveyor belt will cause metal debris to be adsorbed on the belt surface and difficult to fall off on its own. The high friction conveyor belt will leave a layer of oil film as production continues. The debris and oil residue on the conveyor belt will be adsorbed onto the surface of the subsequent new sheet metal, increasing the subsequent rework cost.

[0003] In related technologies, during the belt cleaning process, operators need to stop the production line and use the brush of the cleaning device to clean the oil and particles on the belt surface. After a period of use, the brush wears out, and the cleaning effect is greatly reduced. When the scraper of the cleaning device is used to clean the oil and particles on the belt surface, the oil will splash onto nearby equipment when it comes into contact with the scraper, making it difficult to clean.

[0004] Therefore, it is necessary to design a new belt cleaning device to overcome the above problems. Summary of the Invention

[0005] This application provides a belt cleaning device that can solve the technical problems in the related art, such as the need for operators to stop the production line during belt cleaning, the significant decrease in cleaning effect after a period of use when using the brush of the cleaning device, and the oil splattering onto nearby equipment when using the scraper of the cleaning device, which is difficult to clean.

[0006] In a first aspect, embodiments of this application provide a belt cleaning device, comprising: a housing and a vacuum device, wherein the opening of the housing is covered with a base, the base is provided with a belt mounting groove on the side near the housing, a scraper is provided inside the housing, the scraper is used to contact the surface of the belt; and the vacuum device is connected to the housing.

[0007] The housing has an opening at the top and a drain outlet at the bottom. A base covers the opening, forming a nearly enclosed space. A belt mounting groove is located at the bottom of the base, through which the belt passes, covering the opening of the housing. A scraper removes oil and particulate matter from the belt and has a cleaning function. A vacuum device is located below the housing and communicates with the drain outlet. The vacuum device has a suction function, ensuring effective cleaning of foreign objects while allowing the cleaned oil and particulate matter to be adsorbed and collected, preventing oil splashing. The vacuum device creates a vacuum inside the housing. The vacuum device has a large diameter, enabling it to remove not only liquid oil but also solid particulate impurities, ensuring that oil can be smoothly discharged from the drain outlet during use without clogging.

[0008] In conjunction with the first aspect, in one embodiment, the housing is provided with an air knife, the air knife has a plurality of spaced-apart exhaust holes, and the air knife is inclined and faces the opening of the housing. The housing has a first inclined surface, and the air knife is disposed on the first inclined surface. The front end of the air knife has at least one set of air nozzles, which are connected to an external air source through the exhaust port. The air nozzles face the belt. Preferably, the extension direction of the air knife is perpendicular to the extension direction of the first inclined surface to facilitate the installation and fixation of the air knife. The front end of the air knife has two sets of spaced-apart air nozzles, with equal spacing between adjacent air nozzles in each set. The air knife has a purging function and adopts a flat design to ensure that the air knife generates a large purging force and increases the purging area, enabling the purging of a larger area of ​​the belt. The purging direction of the air knife is opposite to the traveling direction of the belt, ensuring that foreign objects on the belt have a greater relative velocity with respect to the compressed air output by the air knife, achieving a better cleaning effect. The purging of the air knife is completed within the housing, avoiding secondary pollution caused by oil splashing during the cleaning process.

[0009] In conjunction with the first aspect, in one embodiment, an interconnected solenoid valve and a three-way valve are installed outside the housing. The three-way valve is connected to the exhaust port of the air knife through a first speed regulating valve and to the vacuum device through a second speed regulating valve.

[0010] The housing includes a mounting plate on one side, on which the solenoid valve and the three-way valve are mounted. The solenoid valve connects to an external air source, which enters the three-way valve and is then divided into two air sources. The three-way valve has two output ports: one port connects to a first speed control valve, and the other port connects to a second speed control valve. The first air source is delivered to the air knife through the first speed control valve, and the second air source is delivered to the vacuum device through the second speed control valve. The first speed control valve is adjusted to control the blowing force of the air knife according to different working conditions and cleaning requirements, and the second speed control valve is adjusted to control the suction force of the vacuum device. This allows for independent control of the air knife and the vacuum device, achieving optimal cleaning results. Each belt cleaning device is equipped with an independent solenoid valve. Exemplarily, the belt cleaning device performs periodic customized cleaning only when the belt is in motion, achieving energy savings.

[0011] In conjunction with the first aspect, in one embodiment, the housing is provided with at least one support plate, the support plate is provided with at least two guide posts, and the scraper is mounted on at least two of the guide posts.

[0012] In this example, the upper cross-section of the housing is rectangular, and the lower cross-section of the housing is trapezoidal. The support plate is located on the upper part of the housing, and the air knife is located on the lower part of the housing, situated on one side of the drain outlet. Two parallel support plates are arranged inside the housing, and each support plate has two spaced-apart guide posts. The scraper is mounted on the two guide posts, and the distance between the two guide posts is set according to the length of the scraper to ensure the stability of the scraper during use. The scraper is fixed to the guide posts, and the air knife is located between the two support plates in the front-to-back direction, facing the belt.

[0013] In conjunction with the first aspect, in one embodiment, the support plate is provided with a mounting hole, the guide post is movably inserted through the mounting hole, the guide post is sleeved with a first spring, the first spring is located between the scraper and the support plate, and the first spring abuts against the scraper.

[0014] The support plate is equipped with a guide seat, and the guide post is inserted into the guide seat. The guide seat limits the guide post to ensure that the scraper maintains a stable angle during operation. One end of the first spring abuts against the scraper, and the other end of the first spring abuts against the guide seat. Under the action of the first spring, the scraper always maintains a set pressure in contact with the belt to achieve self-compensation after minor wear. At the same time, the scraper rebounds when it is unable to remove foreign objects due to unexpected circumstances, avoiding damage to the cutting edge of the scraper.

[0015] In conjunction with the first aspect, in one embodiment, the base includes a base plate that covers the opening of the housing. The base plate is provided with the belt mounting groove on one side near the housing. Elastic positioning members are provided on both sides of the base plate. The belt mounting groove is located between two elastic positioning members, and the elastic positioning members are used to clamp the belt.

[0016] The base plate provides support for the belt, allowing the scraper to apply sufficient pressure to the belt without causing it to deform. The two elastic positioning elements guide the belt, enabling the belt cleaning device to quickly adapt to belts of different sizes. This ensures that the belt and the scraper maintain stable contact pressure during the cleaning process, preventing cleaning failures caused by installation errors or belt fluctuations.

[0017] In conjunction with the first aspect, in one embodiment, the elastic positioning member includes a positioning block and a second spring connected to each other, the positioning block being located on the side of the elastic positioning member near the belt mounting groove, and the second spring being connected to an adjusting screw, the adjusting screw being inserted into the base plate.

[0018] The bottom of the base plate is provided with a limiting groove, in which the positioning block and the second spring are installed. The limiting groove is connected to the belt mounting groove. The positioning block abuts against the side of the belt. One end of the second spring is fixed to the positioning block, and the other end of the second spring is fixed to the adjusting screw. The second spring can buffer the vibration generated by the belt during operation. The adjusting screw is threaded to the base plate. The adjusting screw is adjusted according to the material of the belt to adjust the guiding force of the elastic positioning element and ensure the best guiding effect.

[0019] In conjunction with the first aspect, in one embodiment, the base plate is provided with supports on both sides.

[0020] The bracket serves as a limiting element and can be replaced according to the appropriate belt conveyor body to facilitate the addition or modification of belt conveyors with various structures.

[0021] In conjunction with the first aspect, in one embodiment, the housing is connected to the base via a sealing structure.

[0022] The housing is connected to the base at its opening by a sealing strip and fixed to the base by screws, forming a closed area inside the housing. During the cleaning process, most of the oil stains generated are controlled within the housing by the vacuum pump, thus avoiding secondary pollution during the cleaning process.

[0023] In conjunction with the first aspect, in one embodiment, the bottom of the vacuum device is connected to a drain pipe.

[0024] The belt cleaning device is configured in a certain number according to the actual needs or working conditions on site. Each belt cleaning device operates independently, and adjacent belt cleaning devices are connected through the sewage pipe, so that multiple belt cleaning devices form a whole. The oil discharged after cleaning will automatically collect to the oil collection point under the action of vacuum suction force. A container can be set at the oil collection point, or the oil discharged after cleaning can be directly discharged to the sewage ditch through the pipeline, avoiding frequent secondary cleaning of oil by manual labor.

[0025] The beneficial effects of the technical solutions provided in this application include: By covering the opening of the housing with a base containing a belt mounting groove and installing a scraper inside the housing, which is connected to a vacuum device, the cleaning effect of foreign objects is ensured while the oil and particulate matter removed can be adsorbed and collected, preventing oil splashing. This solves the technical problems in related technologies where operators need to stop the production line during belt cleaning, the cleaning effect of the brush used by the cleaning device decreases significantly after a period of use, and the use of the scraper of the cleaning device causes oil to splash onto nearby equipment, which is difficult to clean.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0030] This application provides a belt cleaning device that solves the technical problems that require operators to stop the production line during belt cleaning, and that the cleaning effect of the brush used by the cleaning device will decrease significantly after a period of use, while the scraper used by the cleaning device will cause oil to splatter onto nearby equipment and be difficult to clean.

[0031] See Figure 1-4 As shown, this application embodiment provides a belt cleaning device, which includes: a housing 1 and a vacuum device 4. The opening of the housing 1 is covered with a base 2. The base 2 is provided with a belt mounting groove 211 on the side near the housing 1. The housing 1 is provided with a scraper 3, which is used to contact the surface of the belt 100. The vacuum device 4 is connected to the housing 1.

[0032] In this embodiment, the top of the housing 1 is provided with the opening, the bottom of the housing 1 is provided with a drain outlet, and the base 2 covers the opening of the housing 1, forming a nearly enclosed space, such as... Figure 6 and Figure 7As shown, the bottom of the base 2 is provided with a belt mounting groove 211, through which the belt 100 passes, covering the opening of the housing 1. The scraper 3 is used to scrape off the oil and particulate matter attached to the belt 100. The scraper 3 has a cleaning function. The vacuum device 4 is located below the housing 1 and is connected to the drain port. The vacuum device 4 has a suction function, ensuring the cleaning effect of foreign objects while allowing the cleaned oil and particulate matter to be adsorbed and collected, avoiding oil splashing. The vacuum device 4 evacuates the inside of the housing 1. The vacuum device 4 has a large diameter, enabling it to not only suction liquid oil but also solid particulate impurities, ensuring that oil can be smoothly discharged from the drain port during use without clogging.

[0033] This embodiment covers the opening of the housing 1 with a base 2 having a belt mounting groove 211, and sets the scraper 3 inside the housing 1. The housing 1 is connected to the vacuum device 4. This ensures the cleaning effect of foreign objects while allowing the cleaned oil and particulate matter to be adsorbed and collected, avoiding oil splashing. This solves the technical problems in related technologies where operators need to stop the production line during belt cleaning, and the cleaning effect of the brush of the cleaning device will drop significantly after a period of use. The scraper of the cleaning device will cause oil to splash onto nearby equipment, which is difficult to clean.

[0034] Further, see Figure 3-5 As shown, in some embodiments, the housing 1 is provided with an air knife 5, the air knife 5 is provided with a plurality of spaced exhaust holes, and the air knife 5 is inclined and faces the opening of the housing 1.

[0035] In this embodiment, the housing 1 is provided with a first inclined surface 101, and the air knife 5 is disposed on the first inclined surface 101. The front end of the air knife 5 is provided with at least one set of air nozzles, which are connected to an external air source through the exhaust port. The air nozzles face the belt 100. Preferably, the extension direction of the air knife 5 is perpendicular to the extension direction of the first inclined surface 101 to facilitate the installation and fixation of the air knife 5. The front end of the air knife 5 is provided with two sets of spaced air nozzles, and the distance between two adjacent air nozzles in each set is equal. The air knife 5 has a blowing function. The air knife 5 adopts a flat design to ensure that the air knife 5 generates a large blowing force and increases the blowing area, so as to blow a larger area of ​​the belt 100. The blowing direction of the air knife 5 is opposite to the traveling direction of the belt 100, so as to ensure that the foreign objects on the belt 100 have a greater relative velocity with respect to the compressed air output by the air knife 5, thereby achieving a better cleaning effect. The blowing of the air knife 5 is completed within the housing 1, avoiding secondary pollution caused by oil splashing during the cleaning process. In other embodiments, the extending direction of the air knife 5 forms a set angle with the extending direction of the first inclined surface 101, and the angle can be set as an acute angle or an obtuse angle.

[0036] Exemplarily, two spaced-apart scrapers 3 are arranged inside the housing 1 along the moving direction of the belt 100. One of the scrapers 3 has a larger contact edge radius to provide a larger contact force and contact area between the scraper 3 and the belt 100, thereby squeezing and loosening firmly adhered impurities on the belt 100 and dispersing the surface oil of the belt 100, facilitating subsequent blowing and scraping. The other scraper 3 has a smaller contact edge radius to effectively scrape off impurities and residual oil on the surface of the belt 100, thereby ensuring a good cleaning effect. The cooperation of the two scrapers 3 with different blades can improve the cleaning effect on stubborn oil stains on the surface of the belt 100.

[0037] Further, see Figure 1-3 As shown, in some embodiments, a solenoid valve 6 and a three-way valve 7 are installed on the outside of the housing 1. The three-way valve 7 is connected to the exhaust port of the air knife 5 through a first speed regulating valve 8 and to the vacuum device 4 through a second speed regulating valve 9.

[0038] In this embodiment, a mounting plate is provided on one side of the housing 1. The mounting plate is used to install the solenoid valve 6 and the three-way valve 7. The solenoid valve 6 is connected to an external air source. The air source enters the three-way valve 7 through the solenoid valve 6 and is then divided into two air sources through the three-way valve 7. The output end of the three-way valve 7 has two ports. One port of the three-way valve 7 is connected to the first speed regulating valve 8, and the other port of the three-way valve 7 is connected to the second speed regulating valve 9. The first air source is delivered to the air knife 5 after passing through the first speed regulating valve 8, and the second air source is delivered to the vacuum device 4 through the second speed regulating valve 9. According to different working conditions and different cleaning requirements, the first speed regulating valve 8 is adjusted to control the blowing force of the air knife 5, and the second speed regulating valve 9 is adjusted to control the suction force of the vacuum device 4. This allows for independent control of the air knife 5 and the vacuum device 4 to achieve the best cleaning effect. Each belt cleaning device is equipped with an independent solenoid valve 6. Exemplarily, the belt cleaning device performs customized cleaning periodically only when the belt 100 is moving to achieve energy saving.

[0039] Further, see Figure 3-5 As shown, in some embodiments, the housing 1 is provided with at least one support plate 10, the support plate 10 is provided with at least two guide posts 11, and the scraper 3 is mounted on at least two of the guide posts 11.

[0042] In this embodiment, the support plate 10 is equipped with a guide seat 14, and the guide post 11 is inserted into the guide seat 14. The guide seat 14 limits the guide post 11 to ensure that the scraper 3 maintains a stable angle during operation. One end of the first spring 12 abuts against the scraper 3, and the other end of the first spring 12 abuts against the guide seat 14. Under the action of the first spring 12, the scraper 3 always maintains contact with the belt 100 at a set pressure to achieve self-compensation of the scraper 3 after minor wear. At the same time, the scraper 3 rebounds when it is unable to remove foreign objects due to unexpected circumstances, avoiding damage to the cutting edge of the scraper 3.

[0043] In other embodiments, the guide post 11 is fixed to the support plate 10, the guide seat 14 is sleeved on the bottom of the guide post 11, the bottom of the scraper 3 is fixed with a connecting block, one end of the first spring 12 is fixed to the guide seat 14, and the other end of the first spring 12 is fixed to the connecting block.

[0045] In this embodiment, the base plate 21 provides support for the belt 100, allowing the scraper 3 to apply sufficient pressure to the belt 100 without causing deformation. The two elastic positioning members 22 guide the belt 100, enabling the belt cleaning device to quickly adapt to belts 100 of different sizes. This ensures that the belt 100 and the scraper 3 maintain stable contact pressure during the cleaning process, avoiding cleaning failure due to installation errors or belt 100 fluctuations.

[0046] Further, see Figure 6 and Figure 7 As shown, in some embodiments, the elastic positioning member 22 includes a positioning block 221 and a second spring 222 connected to each other. The positioning block 221 is located on the side of the elastic positioning member 22 near the belt mounting groove 211. The second spring 222 is connected to an adjusting screw 223, which is inserted into the base plate 21.

[0047] In this embodiment, the bottom of the base plate 21 is further provided with a limiting groove. The positioning block 221 and the second spring 222 are installed in the limiting groove. The limiting groove communicates with the belt mounting groove 211. The positioning block 221 abuts against the side of the belt 100.

[0048] Further, see Figure 6 and Figure 7 As shown, in some embodiments, the base plate 21 is provided with supports 23 on both sides.

[0049] In this embodiment, the bracket 23 serves as a limiting device. The bracket 23 can be replaced according to the appropriate belt conveyor body so that belt conveyors of various structures can be added or modified.

[0050] Further, see Figure 1 and Figure 2 As shown, in some embodiments, the housing 1 is connected to the base 2 via a sealing structure.

[0051] In this embodiment, the housing 1 is connected to the base 2 at its opening via a sealing strip and is fixed to the base 2 with screws, forming a closed area inside the housing 1.
