[0003] In actual production use, when a conveyor belt is used for transportation, two automobile parts and the solid EVA material in the middle thereof will be squeezed by two heating plates in a preheating furnace. During the extrusion, the solid EVA material melts to connect the two automobile parts. However, during the heating and extrusion process, excess fluid EVA adhesive will overflow and adhere to the conveyor belt. After a long period of accumulation, the surface of the conveyor belt will become seriously dirty, affecting the transmission effect of the conveyor belt and reducing the service life of the conveyor belt. When it is necessary to clean the excess adhesive on the surface of the conveyor belt, manual cleaning is mostly used and the adhesive needs to be cleaned after the machine is shut down. It is inconvenient to clean the adhesive on the surface of the conveyor belt during operation, that is, the cleaning efficiency is not high. In summary, it is necessary to design a conveyor belt surface adhesive strip cleaning device that can automatically clean the adhesive on the surface of the conveyor belt to extend the service life of the conveyor belt.

[0031] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0032] Reference Figure 1-9, a conveyor belt surface adhesive cleaning device, comprising a conveyor frame 1, a first cleaning mechanism 2 and a second cleaning mechanism 3 symmetrically arranged on the inner wall of the conveyor frame 1, and a collecting mechanism 4 installed below the first cleaning mechanism 2: the upper inner wall of the conveyor frame 1 is rotatably connected to a conveyor belt body 5, the first cleaning mechanism 2 is composed of a support shaft 21 fixedly connected to the inner wall of the conveyor frame 1, a support sleeve 22 fixedly arranged outside the support shaft 21, a channel 23 opened on the outer wall of the support sleeve 22, and a scraper 24 rotatably connected to the outer surface of the support sleeve 22, the collecting mechanism 4 is composed of a trough body 41 fixedly arranged on the inner wall of the conveyor frame 1, The conveyor frame 1 is composed of grooves 42 symmetrically and equidistantly opened on the inner wall of the groove body 41, electric heating tubes 43 fixed in the grooves 42, heat conducting plates 44 fixed on the inner wall of the grooves 42, a movable groove 45 opened on one side of the groove body 41 and a collecting groove 46 slidably connected in the movable groove 45. A first scraping mechanism 6 and a second scraping mechanism 7 are provided on one side wall of the conveyor frame 1, and a first driving mechanism 8 and a second driving mechanism 9 are provided on the other side wall of the conveyor frame 1 away from the first scraping mechanism 6 and the second scraping mechanism 7. The structure and working principle of the second cleaning mechanism 3 are consistent with the structure and working principle of the first cleaning mechanism 2.

[0033] With this arrangement, EVA (Ethylene Vinyl Acetate Copolymer) material plays a connecting role in the automotive field as an adhesive. For example, when the conveyor belt body 5 is conveying EVA material, two automobile parts and the EVA material in the middle thereof will be squeezed by two heating plates in the preheating furnace. During the extrusion, the EVA material melts to connect the two automobile parts. However, in the process of heating and extrusion, excess EVA material will fall off and adhere to the conveyor belt body 5, thereby causing the surface of the conveyor belt body 5 to be dirty, affecting its use. The present device is provided with a first cleaning mechanism 2 and a second cleaning mechanism 3 below both ends of the conveyor belt body 5, which can use the two to alternately scrape off the dirt on the surface of the conveyor belt body 5, and make the dirt fall into the collection tank 46 through the channel 23 under the guidance of the scraper 24 for collection. The inner wall of the channel 23 is made of a non-stick coating material. The collection tank 46 An electric heating tube 43 is provided inside to maintain a certain temperature in the collection tank 46 to prevent the EVA material from solidifying, and heat is transferred to the collection tank 46 through the heat conducting plate 44. The material of the heat conducting plate 44 is not limited to metal, ceramic and carbon fiber, etc., so that the cleanliness of the surface of the conveyor belt body 5 can be ensured by the first cleaning mechanism 2 and the second cleaning mechanism 3, and the first cleaning mechanism 2 and the second cleaning mechanism 3 can operate alternately. When a large amount of impurities are adhered to the scraper 24 on the surface of the first cleaning mechanism 2, the scraper 24 can be turned down by the first driving mechanism 8 and the impurities on its surface can be scraped off by the first scraping mechanism 6. At the same time, the second cleaning mechanism 3 is turned up so that its scraper 24 fits with the lower surface of the conveyor belt body 5 to scrape off the impurities on its surface. The cycle is alternating to avoid the scraping performance of the scraper 24 from decreasing and affecting the cleaning efficiency of the conveyor belt body 5.

[0034] The first driving mechanism 8 includes a through slot 81 opened on one side of the conveying frame 1, a driving motor 82 fixedly arranged on a side near the through slot 81, a rotating shaft 83 fixedly arranged at the output end of the driving motor 82, and a semicircular rotating plate 84 fixedly arranged with the rotating shaft 83. The semicircular rotating plate 84 is rotatably connected to the inner wall of the through slot 81, and the semicircular rotating plate 84 is fixedly connected to the scraper 24. A positioning plate 10 is fixedly arranged on the outer wall of one side of the semicircular rotating plate 84. A first limiting plate 11 and a second limiting plate 12 are fixedly arranged on one side of the conveying frame 1 close to the positioning plate 10. A pressure sensor 13 is fixedly arranged on one side of the first limiting plate 11 and the second limiting plate 12. An electric telescopic rod 14 is fixedly arranged on one side of the first limiting plate 11. A through hole 15 is opened on one side of the positioning plate 10. The size of the inner rod of the electric telescopic rod 14 is adapted to the inner diameter of the through hole 15. The structure and working principle of the second driving mechanism 9 are consistent with the structure and working principle of the first driving mechanism 8.

[0035] In this arrangement, when the first cleaning mechanism 2 and the second cleaning mechanism 3 need to be used alternately, when a certain amount of impurities adhere to the surface of the scraper 24 of the first cleaning mechanism 2, causing its cleaning performance to decline, the scraper 24 of the first cleaning mechanism 2 is turned down for cleaning and the scraper 24 of the second cleaning mechanism 3 is turned up for use, the scraper 24 is turned down by the first driving mechanism 8 and rotated to a specified angle to align with the position of the scraper 67 of the first scraping mechanism 6, the driving motor 1 82 is started to drive the rotating shaft 1 83 to rotate, and the rotating shaft 1 83 is on the support shaft The rotating shaft 83 is connected to the support shaft 21 by rotation. The rotating shaft 83 rotates through the knob on the outer surface of the support shaft 21 and the connecting rod between the knob and the semicircular rotating plate 84 to drive the semicircular rotating plate 84 to rotate. The semicircular rotating plate 84 rotates toward one side of the channel 23 on the inner wall of the through groove 81. When the positioning plate 10 on the semicircular rotating plate 84 rotates to the second limit plate 12 and abuts against the pressure sensor 13, the pressure sensor 13 transmits a signal to the PLC controller body 20 (Programmable Logic Controller, programmable logic controller), the PLC controller body 20 controls the drive motor 182 to be turned off, thereby rotating the scraper 24 of the first cleaning mechanism 2 to a specified position and aligning it with the scraper 67 for subsequent impurity cleaning. At the same time, the PLC controller body 20 controls the drive motor 182 of the second drive mechanism 9 to start, and the drive motor 182 drives the semicircular rotating plate 84 to rotate on the inner wall of the through groove 81 to the side away from the channel 23 through the rotating shaft 183, so that the positioning plate 10 no longer abuts the pressure sensor 13 on the second limit plate 12, and drives the scraper 24 to When the positioning plate 10 abuts against the pressure sensor 13 on the side of the first limit plate 11, it indicates that the scraper 24 has rotated to a position that fits the lower surface of the conveyor belt body 5. At this time, the electric telescopic rod 14 is driven to start by the PLC controller body 20, and the inner rod of the electric telescopic rod 14 passes through the through hole 15, thereby limiting the position of the positioning plate 10 and the scraper 24, thereby realizing the downward cleaning of the scraper 24 of the first cleaning mechanism 2 and the upward use of the scraper 24 of the second cleaning mechanism 3 at a specified angle, thereby realizing alternating operation to ensure the cleaning of the surface of the conveyor belt body 5.

[0036] The structure and working principle of the first scraping mechanism 6 are consistent with the structure and working principle of the second scraping mechanism 7. The first scraping mechanism 6 includes a support frame 61 fixed on one side of the conveyor frame 1, a slide 62 and a drive motor 2 63 installed above the support frame 61, a screw 64 fixed at the output end of the drive motor 2 63, a slider 65 movably connected to the outer wall of the screw 64 by a thread, a push plate 66 fixed on one side of the slider 65, and a scraper 67 fixed on one side of the push plate 66. The push plate 66 and the scraper 67 are both movable through the conveyor frame 1, the screw 64 is movable through the slide 62, the shape of the scraper 67 is adapted to the shape of the scraper 24, the scraper 67 is slidably connected to the outer surface of the scraper 24, and the slide 62 and the drive motor 2 63 are both detachable from the support frame 61 by bolts.

[0037] The second drive mechanism 7 is used to start the second scraper 24 of the first cleaning mechanism 2, and the second scraper 24 of the second cleaning mechanism 2 is used to start the second drive mechanism 8. The second drive motor 63 is started by the PLC controller body 20, and the second drive motor 63 drives the screw 64 to rotate in the slide 62. The slide 62 is T-shaped, and the slider 65 is also T-shaped. The screw 64 rotates to drive the slider 65 to move along the inner wall of the slide 62 toward the scraper 24. During the movement, the slider 65 drives the scraper 67 to move through the push plate 66. The scraper 67 moves laterally on the surface of the scraper 24 to scrape off the impurities adhered to its surface and make them fall into the collection trough 46, thereby facilitating the cleaning and collection of impurities on the surface of the scraper 24 of the first cleaning mechanism 2. Similarly, when the scraper 24 of the second cleaning mechanism 3 needs to be cleaned, it only needs to be rotated downward to the specified position by the second drive mechanism 9, and then the second scraping mechanism 7 can be used to remove the impurities on the surface of the scraper 24 of the second cleaning mechanism 3. It is easy to use and improves the cleaning performance of the scraper 24 on the conveyor belt body 5.

[0038] A drive motor 3 16 is fixedly provided on one side wall of the conveyor frame 1, and a rotating shaft 2 17 is fixedly provided on the output end of the drive motor 3 16. A rotating shaft 18 is rotatably connected to the inner wall of the conveyor frame 1 away from the rotating shaft 2 17. The rotating shaft 18 and the rotating shaft 2 17 are both rotatably connected to the inner wall of the conveyor belt body 5. The outer surfaces of the rotating shaft 2 17 and the rotating shaft 18 are provided with an anti-slip layer 19. A PLC controller body 20 is fixedly provided on one side wall of the conveyor frame 1.

[0039] With such a configuration, the driving motor 3 16 can drive the conveyor belt body 5 to rotate through the rotating shaft 2 17 and the anti-slip layer 19, and the conveyor belt body 5 drives the rotating shaft 18 to rotate, thereby achieving the purpose of transmission. The PLC controller body 20 is a Siemens ‌S7-200 SMART type, and the automatic operation of the equipment can be realized through the PLC controller body 20 (Programmable Logic Controller).

[0040] When the impurities on the surface of the scraper 24 of the first cleaning mechanism 2 need to be cleaned, the scraper 24 of the first cleaning mechanism 2 is rotated downward to the specified position by the first driving mechanism 8 and the impurities on its surface are cleaned by the first scraper 6. At the same time, the second driving mechanism 9 drives the scraper 24 of the second cleaning mechanism 3 to rotate upward to clean the conveyor belt 5. This is alternating operation. The advantage of this method is that it can continuously clean the dirt on the surface of the conveyor belt 5 without stopping the machine, thereby improving the cleaning efficiency and reducing power consumption.

[0041] Another method is also provided. The second method is to clean the dirt on the surface of the conveyor belt body 5 through synchronous operation, that is, the first cleaning mechanism 2 and the second cleaning mechanism 3 clean the dirt on the surface of the conveyor belt body 5 at the same time, that is, after the conveyor belt body 5 passes through the first cleaning mechanism 2 for one cleaning, it is cleaned a second time when it rotates to the second cleaning mechanism 3. When it is necessary to scrape impurities on the surface of the scraper 24 of the first cleaning mechanism 2 and the scraper 24 of the second cleaning mechanism 3, it is necessary to start the first driving mechanism 8 and the second driving mechanism 9 at the same time to turn down the two scrapers 24, and scrape the impurities on the surface of the two scrapers 24 into the collection tank 46 through the first scraping mechanism 6 and the second scraping mechanism 7. This method cleans the dirt on the surface of the conveyor belt body 5 more thoroughly, but the scraper 24 needs to be cleaned when the machine is stopped. Both methods are methods that can be implemented by this equipment, so that it can meet different usage requirements and effectively improve the practicality of the equipment.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the scope of the present invention.
