Abstract
Description
Technical Field
[0001] This utility model relates to a rubber product processing method, and in particular to a pneumatic cleaning device for removing burrs from rubber products. Background Technology
[0002] The fuel filler cap guide valve is an important component of the automotive fuel system, primarily used to control the opening and closing of the fuel nozzle cap on the fuel filler cap, ensuring the normal operation of the fuel system. To ensure the sealing and sensitivity of the fuel tank's opening and closing mechanism, rubber components are used as sealing structures within the fuel tank to assist in its operation.
[0003] Currently, rubber product processing typically involves first melting rubber into a fluid state, then using die casting or injection molding to determine the shape of the rubber product. Finally, a cleaning device and manual labor are used, employing a pulling device in conjunction with upper and lower molds, to remove the internal and external flash from the rubber product, completing the processing steps. However, existing flash removal devices mostly remove the internal and external flash separately, resulting in a cumbersome process, long processing time, slow production speed, and difficulty in quickly separating the product from the flash. Therefore, it is necessary to design a rubber product cleaning device that can quickly remove the internal and external flash from rubber products and use a gas-driven method to collect the product and flash separately. Utility Model Content
[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a pneumatic cleaning device for removing flash from rubber products, which realizes that the cleaning device can remove the inner and outer flash of rubber products at the same time, and uses gas drive to collect the product and flash separately.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A pneumatic cleaning device for trimming and removing burrs from rubber products includes a processing table, an upper substrate and an upper template disposed on top of the processing table, and a lower substrate and a lower template disposed on the processing table. Multiple ejector components are disposed through the bottom of the upper substrate and the upper template. An air pump is externally connected to each ejector component. The bottom of the multiple ejector components is provided with the same unloading plate. Multiple material distribution components are disposed through the lower substrate and the lower template for simultaneously cutting the inner and outer burrs of the product by the material distribution components and the ejector components.
[0007] Preferably, the top material assembly includes a top pin pressure plate fixed to the bottom of the upper template, and the same outer separator is provided through the upper base plate, the upper template, the top pin pressure plate and the unloading plate, and an inner separator is provided through the middle of the outer separator.
[0008] Preferably, the outer separating component includes a product upper ejector pin that passes through the upper template, ejector pin pressure plate, and unloading plate, and the product upper ejector pin has a suction hole that is connected to the air pump.
[0009] Preferably, the inner separating component includes a top material spring that penetrates the upper substrate, the upper template, and the ejector pin plate. The lower end of the top material spring is provided with a fixing seat, and a top edge spring is sleeved in the fixing seat. A spring plunger is fixed at the bottom of the top edge spring, and the lower end of the spring plunger penetrates the unloading plate.
[0010] Preferably, the upper substrate, the upper template, and the unloading plate are connected by the same level column, and the unloading spring is sleeved on the outside of the level column and is fixedly connected to the upper template and the unloading plate.
[0011] Preferably, the upper substrate, the upper template, and the unloading plate are connected by a common guide post, and the unloading plate and the lower template are both provided with guide sleeves that cooperate with the guide post.
[0012] Preferably, the material separating assembly includes an edge material ejector pin that penetrates the lower substrate and the lower template. The edge material ejector pin is fitted with a material support spring that is fixed to the lower substrate. The top of the material support spring is fixed with a product lower ejector pin, and the product lower ejector pin penetrates the edge material ejector pin, for the simultaneous separation of the product from the inner and outer flash.
[0013] Preferably, a discharge port is provided on the processing table below the unloading plate, and a screening component is provided at the bottom of the discharge port for screening products and waste. The screening component includes a horizontal drive component fixedly connected to the processing table, a screen is rotatably provided at the drive end of the horizontal drive component, and vibrating slide rails connected to the processing table are provided on both sides of the screen. A waste bin and a receiving bin are provided below the screen.
[0014] Compared with existing technologies, the pneumatic cleaning device for removing flash from rubber products provided by this utility model can simultaneously remove the inner and outer flash of rubber products, using gas drive to collect the product and flash separately. By setting the ejector assembly on the upper template and upper substrate, and the separating assembly on the lower template and lower substrate, the device facilitates the use of the product's upper ejector pin to press down on the product's lower ejector pin, allowing the ejector pin to penetrate and pull out the flash from the inner diameter of the rubber product, simultaneously cleaning the inner and outer flash. This reduces the number of flash cleaning steps and improves the efficiency of flash cleaning. Then, through the suction hole in the product's upper ejector pin, the air pump in the suction hole applies negative pressure to adsorb the cleaned product onto the unloading plate, separating it from the flash. Afterwards, by pulling out and resetting the lower template, the air pump blows air, converting the negative pressure in the suction hole into high-pressure air, allowing the product to fall and be removed, completing the flash removal and unloading steps of the rubber product. This achieves simultaneous processing of the inner and outer flash of the rubber product, reducing processing steps and improving the processing efficiency of the device.
[0015] Furthermore, the use of screening components at the feed inlet of the processing table can fully separate the product from the flash, collect and transfer the product in a unified manner, increase the product screening structure of the cleaning device, ensure the cleanliness of the output product, and is very beneficial for the rapid output of rubber products.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0027] As attached Figure 1 To be continued Figure 6 As shown, this utility model provides a pneumatic cleaning device for removing burrs from rubber products, used for the rapid removal of inner and outer burrs from rubber products. The device uses a gas pump to collect the product and burrs separately. Existing burr removal devices include a processing table 1, an upper substrate 11 and an upper template 12 mounted on top of the processing table 1, and a lower substrate 14 and a lower template 13 mounted on the processing table 1. The upper substrate 11, upper template 12, lower template 13, and lower substrate 14 are arranged sequentially from top to bottom. The rubber product is a single sheet, laid flat on the lower template 13. By pushing the lower substrate 14 towards the upper substrate 11, the upper template 12 and lower template 13 are aligned. Then, the processing table 1 presses the upper template 12 towards the lower template 13, cutting the inner and outer burrs of the entire rubber product. To achieve simultaneous cutting of the inner and outer burrs, multiple top-feeding components 3 can be installed through the bottom of the upper substrate 11 and upper template 12. An air pump is then connected to the outside of the top-feeding components 3, which can be mounted on the upper substrate 11. Then, multiple top-feeding components... The bottom of component 3 is equipped with the same unloading plate 31. When the upper template 12 and the lower template 13 are pressed down and released, the unloading plate 31 can assist the top material assembly 3 in separating the outer flash from the cleaned product, so that the unloading plate 31 can press down the outer flash and avoid the flash passing through multiple top material assemblies 3 and causing retention. Then, multiple material distribution assemblies 4 are arranged through the lower base plate 14 and the lower template 13. Through the cooperation of the material distribution assembly 4 and the top material assembly 3, the inner and outer flash of the rubber product are cut at the same time, improving the processing efficiency. The number of top material assembly 3 and the number of material distribution assembly 4 determine the number of rubber products processed by the device, and the number of the two structures is the same. After the processed product is separated from the lower template 13 and the upper template 12, it is adsorbed onto the material distribution assembly 4 by the air pump. With the air pump blowing air, the processed product can be blown to a unified position for collection, realizing the rapid discharge of rubber products.
[0028] It is worth noting that, for example Figure 3As shown, in some embodiments, the top material assembly 3 may be provided with a top pin pressure plate 34 at the bottom of the upper template 12, and the same outer separator 32 may be provided through the upper substrate 11, the upper template 12, the top pin pressure plate 34 and the unloading plate 31. By pressing the upper template 12 down to the lower template 13, the outer separator 32 can be used to pull the product out of the whole rubber product. Then, the inner separator 33 provided through the middle of the outer separator 32 can work with the material distribution assembly 4 to remove the inner flash of the product, so as to realize the rapid separation of the product from the whole rubber product. The device cleans the inner and outer flash of the product at the same time.
[0029] In some embodiments, to facilitate the separate collection of processed products and flash, the outer separator 32 can be disposed through the upper ejector pin 322 between the upper template 12, the ejector pin plate 34 and the unloading plate 31. The upper ejector pin 322 is fixed on the upper template 12. The upper ejector pin 322 is then configured as a hollow structure. A suction hole 323 connected to the air pump is opened on the upper ejector pin 322. The suction hole 323 is connected to the upper ejector pin 322, providing favorable conditions for pneumatic suction and blowing of the product below the upper ejector pin 322. When the cleaning device is used, the existing air pump is used for gas suction or blowing. By using the negative pressure suction and high pressure blowing of the air pump, the processed product and flash can be separated. The negative pressure gas suction limits the product on the unloading plate 31. When the lower template 13 is pulled out for re-feeding, the high pressure gas blowing discharges the product.
[0030] It is worth noting that, for example Figure 2 As shown, the inner separating component 33 includes a top spring 334 that passes through the upper substrate 11, the upper template 12 and the ejector plate 34. The upper end of the top spring 334 is fixed on the upper substrate 11, and a fixing seat 331 is provided at the lower end of the top spring 334. The lower end of the top spring 334 abuts against the fixing seat 331. Then, a top edge spring 332 is sleeved in the middle of the fixing seat 331. A spring plunger 333 is fixed at the bottom of the top edge spring 332. The lower end of the spring plunger 333 passes through the unloading plate 31. During the cleaning of the inner flash, the spring plunger 333 first contacts the inner flash, and the spring plunger 333 squeezes the top edge spring 332. Then the fixed seat 331 squeezes the ejector spring 334, forming a stepped movement trend, separating the inner flash from the rubber product. After the upper and lower molds open, the top edge spring 332 and ejector spring 334 slowly reset in a stepped manner, pressing the inner flash against the lower mold plate 13, completing the cleaning of the inner flash.
[0031] To facilitate more stable removal of burrs from rubber products, a common equal-height column 21 can be installed between the upper substrate 11, the upper template 12, and the unloading plate 31. An unloading spring 22 is then fitted around the equal-height column 21 and fixedly connected to the upper template 12 and the unloading plate 31. During burr removal, the unloading plate 31 first presses down on the burrs of the rubber product, squeezing the unloading spring 22. The product ejector pin 322 presses down on the product and then presses against the edge ejector pin 41. The edge ejector pin 41 pushes up the inner burrs, separating the inner and outer burrs from the product, allowing the inner burrs to be pressed onto the edge ejector pin 41. Then, through the reset of the upper template 12, the unloading spring 22 assists the unloading plate 31 in resetting, separating the outer burrs from the product ejector pin 322.
[0032] Furthermore, such as Figure 3 As shown, a single guide post 51 can be provided through the upper substrate 11, the upper template 12, and the unloading plate 31. The upper end of the guide post 51 can be fixed to the upper substrate 11. Then, guide sleeves 52 that cooperate with the guide post 51 are provided on both the unloading plate 31 and the lower template 13, so that the device can use the guide post 51 to align the upper template 12 and the lower template 13 for precise processing.
[0033] In some embodiments, the material distribution assembly 4 provides an edge material ejector pin 41 through the lower substrate 14 and the lower template 13 as an inner flash cleaning structure for the rubber product. A material support spring 43 is sleeved on the outside of the edge material ejector pin 41. The material support spring 43 can be fixed to the lower substrate 14. A product lower ejector pin 44 is fixed on the top of the material support spring 43. The product lower ejector pin 44 passes through the edge material ejector pin 41. The upper side of the product lower ejector pin 44 is flush with the lower template 13, which provides favorable conditions for the simultaneous separation of the product from the inner and outer flash and assists in separating the product from the whole rubber product.
[0034] In some embodiments, the processing table 1 can be provided as the discharge end on the lower side of the upper template 12, and a discharge port can be opened on the processing table 1 on the lower side of the unloading plate 31. Then, a screening component 6 is provided at the bottom of the discharge port to facilitate the device to screen the cleaned rubber products and waste materials and prevent the inner and outer flash from being retained.
[0035] To achieve better product and waste screening, such as Figure 1 and 6As shown, the screening component 6 can be fixed to the horizontal drive component 61 on the processing table 1. The drive component 61 can be a cylinder or an electric actuator. Then, the screen 63 is rotated and set at the drive end of the horizontal drive component 61. Vibrating slide rails 62 connected to the processing table 1 are set on both sides of the screen 63. Finally, a waste bin for collecting burrs and a collection bin for collecting products are set below the screen 63. The end of the screen 63 can be equipped with a motor as a drive structure. The use angle of the screen 63 can be adjusted by driving the motor. When the screen 63 is used horizontally, it collects the material at the discharge port of the cleaning device. Then, the screen 63 is pushed by the horizontal drive component, which vibrates the screen 63 using the vibrating slide rail 62 to separate the inner diameter flash of the screen 63 from the product. The flash falls into the waste bin for collection by its own weight. The screened product can be guided by the inclined screen 63 to the collection bin for collection. Finally, the outer flash can be removed by the worker through the high pressure blowing of the air pump and collected. The inner flash on the lower template 13 can be cleaned by the absorption of the dust collector, thus completing the flash removal work of the rubber products, reducing the processing steps of the device and improving the production efficiency of the device.
[0036] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
