[0001] The utility model relates to the technical field of sealing ring production, in particular to a surface burr removal device for nitrile rubber sealing rings. Background Art

[0002] During the processing of rubber products and other parts, the edges of rubber products are prone to form thorns or flash, which are usually called burrs. Although the size of burrs is not large, they directly affect the quality of the product. With the attention of various industries to burr removal, the methods of deburring are constantly innovating. Commonly used methods include chemical deburring, electrolytic deburring, ultrasonic deburring, high-pressure water jet deburring, and magnetic deburring.

[0003] After checking the publication number: CN215788783U, a burr cleaning device for rubber product production is disclosed. This technology discloses "a burr cleaning device for rubber product production, involving the field of rubber production technology, including a device body and a collecting component, a collecting component is arranged outside the device body, the collecting component includes a handle and a debris collecting drawer, a handle is arranged outside the collecting component, a debris collecting drawer is installed inside the collecting component, the device body includes a box body and a deburring platform, a box body is arranged outside the device body, and a deburring platform is installed in the middle of the box body" and other technical solutions, with "through the clamping mechanism structure, the deburring platform is convenient for limiting and fixing the rubber products that need to be polished, avoiding the jamming of the rubber products during transportation, and through the retaining groove and collecting component structure, it is convenient to limit and fix the collecting component inside the retaining groove, improve the stability of the connection between the deburring platform and the collecting component, facilitate the scraping and cleaning of the burr debris falling off the surface of the conveyor belt, and also facilitate the centralized collection of the scraped burr debris" and other technical effects;

[0004] Since nitrile rubber sealing rings lack a positioning mechanism during the process of cleaning surface burrs, the sealing rings are prone to position displacement during the processing, resulting in the deburring tool being unable to accurately act on the target area, thus affecting the processing accuracy; and, the process of cleaning burrs cannot be automatically turned over, resulting in some burrs may not be completely removed, resulting in a decrease in product surface quality. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a surface burr removal device for a nitrile rubber sealing ring, which has the characteristics of avoiding positional deviation during the deburring process and affecting the processing accuracy through a positioning component, and realizing automatic turning over of the nitrile rubber sealing ring through a main body component, so that burrs can be removed on both sides and product quality can be improved.

[0006] To achieve the above purpose, the utility model is implemented by the following technical scheme: a surface burr removal device for a nitrile rubber sealing ring, comprising a processing table, on which a conveying mechanism is provided and used for positioning and turning over the nitrile rubber sealing ring, the conveying mechanism comprising:

At the same time, the sliding rod drives the positioning head to move, and the positioning heads on both sides are used to position the nitrile rubber sealing rings between them, thereby avoiding position offset during the deburring process and affecting the processing accuracy.

[0017] (2) The nitrile rubber sealing ring is transported to the upper conveyor belt through a vibrating plate, guided by an upper limit plate, deburred by a first grinder, and then falls from a limit frame into a reverse slope, and is turned over in the process of falling from the reverse slope into the lower conveyor belt below; it is guided by a lower limit plate, deburred by a second grinder, and then falls from the slope into a collection box for collection; the nitrile rubber sealing ring is automatically turned over, and burrs can be removed on both sides, thereby improving product quality.

[0025] The main assembly 21 includes a lower conveyor belt 212 fixed to the top of the processing table 1 through a stand 211, and an upper conveyor belt 213 fixed to the upper end of the stand 211;

[0026] The positioning assembly 22 includes a limit seat 221 fixed on both sides of the top of the lower conveyor belt 212 and both sides of the top of the upper conveyor belt 213, a slide rod 222 installed for transverse sliding inside the limit seat 221, a positioning head 223 installed at the inner end of the slide rod 222, an axis frame 228 fixed to the outer walls at both ends of the lower conveyor belt 212 and the outer walls at both ends of the upper conveyor belt 213, a support rod 2211 pivotally connected to the axis frame 228, a connecting rod 2210 pivotally connected to the upper end of the support rod 2211, and the other end of the connecting rod 2210 is pivotally connected to the outer end of the slide rod 222.

[0027] In this embodiment, when the support rod 2211 rotates, the connecting rod 2210 drives the sliding rod 222 to slide horizontally along the limit seat 221. At the same time, the sliding rod 222 drives the positioning head 223 to move. The nitrile rubber sealing rings between the positioning heads 223 on both sides are used to position the positions, thereby avoiding position deviation during the deburring process and affecting the processing accuracy.

[0028] Specifically, the positioning assembly 22 also includes a horizontal frame 224 fixed to the upper end of the lower conveyor belt 212 and the upper end of the upper conveyor belt 213, a guide rod 225 fixed at the bottom center of the horizontal frame 224, a sliding sleeve 226 longitudinally slidably installed on the guide rod 225, a support rod 227 pivotally connected at both ends of the sliding sleeve 226, and the other end of the support rod 227 is pivotally connected to the inner end of the support rod 2211.

[0029] In this embodiment, when the support rod 2211 rotates, the sliding sleeve 226 is driven to slide along the guide rod 225 by the support rod 227, thereby ensuring that the rotation amplitudes of the support rods 2211 on both sides are synchronized.

[0030] Specifically, the positioning assembly 22 further includes an extension rod 229 fixed to the lower end of the support rod 2211 and an electric push rod 2212 pivotally connected between the extension rods 229 on both sides.

[0036] Specifically, a vibration plate 4 is installed at the rear end of the top of the processing table 1 , and a second grinder 6 and a first grinder 5 are installed on the left and right sides of the top of the processing table 1 , respectively.

[0037] In this embodiment, the nitrile rubber sealing ring is transported to the upper conveyor belt 213 by the vibration plate 4, and the two sides of the nitrile rubber sealing ring are deburred by the first grinder 5 and the second grinder 6 respectively.

[0038] The working principle and use process of the utility model are as follows: first, the nitrile rubber sealing ring is transported to the upper conveyor belt 213 through the vibration plate 4, and is guided by the upper limit plate 215 until it is transported to the bottom of the first grinder 5; the output end of the electric push rod 2212 is extended and retracted, so that the extension rods 229 on both sides can be driven to respectively drive the support rods 2211 on both sides to rotate in the opposite direction, and when the support rods 2211 rotate, the sliding sleeves 226 are driven to slide along the guide rods 225 through the support rods 227, so as to ensure that the rotation amplitudes of the support rods 2211 on both sides are synchronized, and when the support rods 2211 rotate, the sliding rods 222 are driven to slide horizontally along the limit seats 221 through the connecting rods 2210, and at the same time, the sliding rods 222 drive the positioning heads 223 to move, and the nitrile rubber sealing rings between the positioning heads 223 on both sides are positioned; then the first grinder 5 performs a deburring treatment on one side;

[0039] Then, the nitrile rubber sealing ring falls from the limit frame 216 into the reverse slope 214, and is turned over while falling into the lower conveyor belt 212 below through the reverse slope 214, and is guided by the lower limit plate 217 until it is transported to the bottom of the second grinder 6, and after positioning, the other side is deburred; finally, it falls from the slope 218 into the collection box 3 for collection.
