Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and particularly relates to a rapid dust removal device for sealing rubber rings. Background Art

[0002] A sealing ring is a fitting used for sealing purposes, which can have good sealing performance within a working pressure and a certain temperature range, and can automatically improve the sealing performance as the pressure increases. It is usually made of materials such as rubber and polytetrafluoroethylene, and is widely used in various sealing occasions, such as hydraulic systems, chemical equipment, food processing and other fields. Before the sealing ring is packed in boxes after processing, it needs to be dusted. At present, the sealing rubber ring is usually dusted by an air gun.

[0003] At present, there are already some prior arts that can remove dust from various positions of the sealing rubber ring. For example, the patent publication number is CN215879049U. Its main technical means is that through a fixed nozzle and a moving nozzle, the dust attached to the sealing rubber ring can be peeled off, and the fan collects the dust to avoid secondary pollution of the dust. By setting a rotating bracket and a lifting platform, the fixed nozzle and the moving nozzle can efficiently remove dust from various positions of the sealing rubber ring on the rotating bracket. After analysis, the disadvantages of this technical solution are as follows: The connecting seat and the hook are used as the support plates to support the sealing rubber ring, and the contact surface between the sealing rubber ring and the support is constant, so it cannot effectively contact the airflow generated by the fan, resulting in cleaning dead corners on the sealing rubber ring. When the sealing rubber rings collide during cleaning and collection, the dust on this cleaning dead corner will contaminate other sealing rubber rings, and the sealing rubber rings in the cleaning box are not efficiently dusted. Based on this, the present invention provides a rapid dust removal device for sealing rubber rings that can ensure that there are no cleaning dead corners on the sealing rubber ring to ensure that each sealing rubber ring in the collection box is efficiently dusted. Summary of the Invention

[0004] The purpose of the present invention is to provide a rapid dust removal device for sealing rubber rings in view of the deficiencies of the prior art, so as to solve the technical problem that there are cleaning dead corners on the sealing rubber ring, resulting in inefficient dust removal of each sealing rubber ring in the collection box.

[0005] The purpose of the present invention can be achieved by the following technical solutions: A rapid dust removal device for sealing rubber rings, comprising: A dust removal box, in which there are two symmetrically arranged support plates for supporting the bottom of the sealing rubber ring. A number of balls in contact with the bottom of the sealing rubber ring are rotatably installed on each support plate, and the number of balls is driven to rotate by a driving source. The bottom of the dust removal box is communicated with a dust collection box, and a filter screen is provided at the communication part between the two. A fan is provided in the dust collection box; A limiting plate, several of the limiting plates are in contact with the side of the sealing rubber ring, and adjacent two of the limiting plates are connected by a connecting rod. Several of the limiting plates are respectively installed on several sliders, and several of the sliders are all slidably installed on a slide rail. The slide rail is fixedly connected to a positioning frame fixed in a dust removal box, and the slide rail is coaxially arranged with the sealing rubber ring; and A first air gun, which is communicated with an air storage cavity installed in the dust removal box and is arranged towards a limiting plate. The first air gun blows air to drive the limiting plate to rotate, and the slider slides on the slide rail.

[0006] As a further scheme of the present invention: A second air gun is communicated with the air storage cavity, and the second air gun is arranged towards the sealing rubber ring on the support plate.

[0007] As a further scheme of the present invention: A runner is rotatably installed on the contact surface between the limiting plate and the side of the sealing rubber ring.

[0008] As a further scheme of the present invention: The limiting plate is obliquely arranged, and the horizontal distance between its bottom and the axis of the sealing rubber ring is less than the horizontal distance between its top and the axis of the sealing rubber ring.

[0009] As a further scheme of the present invention: A feeding box coaxially arranged with the slide rail is arranged in the dust removal box. The air storage cavity is fixed on the feeding box. The bottom of the feeding box is open, and an intermittent component is arranged on the feeding box.

[0010] As a further scheme of the present invention: The intermittent component includes a baffle and an output source for driving the baffle to translate. The two baffles are symmetrically arranged at the bottom of the feeding box. When the output source drives the two baffles to expand outwards, the sealing rubber ring in the feeding box can fall between several limiting plates and slide along the limiting plates to the two support plates.

[0011] As a further scheme of the present invention: A collection box is fixed on the filter screen, and two symmetrically arranged cover plates are slidably installed on the top of the collection box. The positioning frame is fixed above the collection box, and the cover plates are slidably matched with the positioning frame. The two support plates are respectively fixed on the two cover plates. A transmission component is arranged on the positioning frame. After the dust removal is completed, the transmission component drives the two cover plates to move away from each other, and at the same time the two support plates move away from each other, so that the dust-removed sealing rubber ring can fall into the open collection box.

[0012] As a further scheme of the present invention: The transmission component includes: A gear, which is coaxially fixedly connected to a rotating shaft, and the rotating shaft is rotatably installed on the positioning frame. The rotating shaft is driven to rotate by an external power source. The number of the gears is two; and Rack bars, the two rack bars are respectively fixedly installed on the two cover plates, and the two rack bars are respectively meshed with the two gears. The moving directions of the two rack bars are opposite.

[0013] As a further solution of the present invention: a dust adhering layer is provided on the inner wall of the collection box.

[0014] Advantages of the present invention: (1) In the present invention, the bottom of the sealing rubber ring is supported by rotatable balls, and several limiting plates in contact with the side of the sealing rubber ring are also rotatable. During dust removal, the relative positions between the support members at the bottom of the sealing rubber ring and the support members on the side of the sealing rubber ring can be changed, so that all regions on the sealing rubber ring can be in full contact with the air flow, which can avoid the problem of cleaning dead corners on the surface of the sealing rubber ring caused by support. After all regions on the sealing rubber ring are fully dust-removed and then collected, it will not cause secondary contamination between the dust-removed sealing rubber rings due to cleaning dead corners, improving the speed and thoroughness of dust removal of the sealing rubber ring; (2) In the present invention, the sealing rubber ring falling between several limiting plates can slide down to the two support plates under the guidance of the limiting plates. The two support plates are in contact with the bottom edge of the sealing rubber ring to ensure the accuracy of the placement position of the sealing rubber ring, while minimizing the support area while ensuring the support force, so as to reduce the possibility of generating cleaning dead corners; (3) In the present invention, an external power source is used to drive the rotation of the two rotating shafts, driving the two racks to move in opposite directions, then the two cover plates move in opposite directions, and the two support plates move synchronously in opposite directions, so that the dust-removed sealing rubber ring can freely fall. When the distance between the two cover plates is the largest, the top opening of the collection box is open, and at this time the dust-removed sealing rubber ring can fall into the collection box to realize the automatic collection of the dust-removed sealing rubber ring, and no other structural components are required to clamp and move during this process. The dust-free environment in the dust removal box can ensure that the dust-removed sealing rubber ring will not be secondarily contaminated. Description of the Drawings

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 4 As shown, the present invention is a rapid dust removal device for sealing rubber rings, including: A dust removal box 1, in which there are two symmetrically arranged support plates 2 for supporting the bottom of the sealing rubber ring. A plurality of balls 5 in contact with the bottom of the sealing rubber ring are rotatably installed on each support plate 2, and the plurality of balls 5 are driven to rotate by a driving source. The bottom of the dust removal box 1 is communicated with a dust collection box 21, and a filter screen 20 is provided at the communication part between the two. A blower is provided in the dust collection box 21; Limiting plates 6, a plurality of the limiting plates 6 are in contact with the side of the sealing rubber ring. Adjacent two of the limiting plates 6 are connected by a connecting rod 10. The plurality of limiting plates 6 are respectively installed on a plurality of sliders 7, and the plurality of sliders 7 are all slidably installed on a slide rail 8. The slide rail 8 is fixedly connected to a positioning frame 18 fixed in the dust removal box 1, and the slide rail 8 is coaxially arranged with the sealing rubber ring; and A first air gun 13, which is communicated with an air storage cavity 15 installed in the dust removal box 1 and is arranged towards one limiting plate 6. The first air gun 13 blows air to drive the limiting plate 6 to rotate, and the slider 7 slides on the slide rail 8.

[0020] In one case of this embodiment, the driving source can be a motor assembly, or a gear assembly or a pulley assembly driven by a motor, as long as it can make the balls 5 rotate. This embodiment does not make specific limitations here; a pressure pump is provided at the connection between the first air gun 13 and the air storage cavity 15; the rotation speed of the balls 5 is different from the rotation speed of the limiting plates 6.

[0021] In actual application of this embodiment, two support plates 2 are used to carry the sealing rubber ring. At this time, the ball bearings 5 are in contact with the bottom of the sealing rubber ring. When the first air gun 13 outputs high-pressure air, the fan starts. The airflow can remove the dust on the surface of the sealing rubber ring, and the fan generates negative pressure during operation, causing the dust to enter the dust collection box 21 through the filter screen 20 in sequence for centralized recovery. During this process, the first air gun 13 blows several limit plates 6 to rotate. At this time, the slider 7 slides on the slide rail 8, and at the same time, the rotation of the ball bearings 5 drives the sealing rubber ring to rotate. In this way, the relative position between the support member (i.e., the ball bearings 5) at the bottom of the sealing rubber ring and the sealing rubber ring can be changed, and at the same time, the relative position between the support member (i.e., the limit plates 6) on the side of the sealing rubber ring and the sealing rubber ring can be changed. All areas on the sealing rubber ring can be in full contact with the airflow, which can avoid the problem of cleaning dead spots on the surface of the sealing rubber ring caused by support. After all areas on the sealing rubber ring are fully dust-removed and then collected, it will not cause secondary contamination between the dust-removed sealing rubber rings due to cleaning dead spots, improving the speed and thoroughness of dust removal of the sealing rubber ring.

[0022] As Figures 1 - 2 shown, as a preferred embodiment of the present invention, a second air gun 14 is connected to the air storage cavity 15, and the second air gun 14 is arranged facing the sealing rubber ring on the support plate 2.

[0023] In one case of this embodiment, a pressure pump is provided at the connection between the second air gun 14 and the air storage cavity 15.

[0024] In actual application of this embodiment, the second air gun 14 arranged facing the sealing rubber ring on the support plate 2 can effectively increase the contact area between the airflow and the sealing rubber ring, thereby increasing the dust removal area to achieve rapid dust removal of the sealing rubber ring.

[0025] As Figures 1 - 4 shown, as a preferred embodiment of the present invention, a runner 9 is rotatably installed on the contact surface between the limit plate 6 and the side of the sealing rubber ring.

[0026] In actual application of this embodiment, the arrangement of the runner 9 can reduce the wear between the limit plate 6 and the sealing rubber ring and improve the qualification rate of the sealing rubber ring.

[0027] As Figures 1 - 4 shown, as a preferred embodiment of the present invention, the limit plate 6 is arranged obliquely, and the horizontal distance between its bottom and the axis of the sealing rubber ring is less than the horizontal distance between its top and the axis of the sealing rubber ring.

[0028] In actual application of this embodiment, the sealing rubber ring that falls between several limiting plates 6 can slide down to the two support plates 2 under the guidance of the limiting plates 6. The two support plates 2 are in contact with the bottom edge of the sealing rubber ring to ensure the accuracy of the placement position of the sealing rubber ring, minimize the support area while ensuring the supporting force, and reduce the possibility of generating cleaning dead corners.

[0029] As Figures 1 - 2 shown, as a preferred embodiment of the present invention, a feeding box 3 coaxial with the slide rail 8 is arranged in the dust removal box 1. The air storage cavity 15 is fixed on the feeding box 3. The bottom of the feeding box 3 is arranged in an open manner, and an intermittent component is arranged on the feeding box 3.

[0030] In one case of this embodiment, the intermittent component includes a baffle 16 and an output source 17 for driving the baffle 16 to translate. The two baffles 16 are symmetrically arranged at the bottom of the feeding box 3. When the output source 17 drives the two baffles 16 to expand outward, the sealing rubber ring in the feeding box 3 can fall between several limiting plates 6 and slide down to the two support plates 2 along the limiting plates 6.

[0031] Among them, the output source 17 can select components such as hydraulic cylinders and air cylinders, and other mechanisms that can achieve linear motion can also be selected, which will not be elaborated here; of course, the intermittent component can also select other structural components such as a shielding baffle that can be opened regularly, as long as it can achieve intermittent feeding of the sealing rubber ring in the feeding box 3, and this embodiment will not be specifically limited here.

[0032] In actual application of this embodiment, in the initial state, the two baffles 16 are in contact with the bottommost sealing rubber ring in the feeding box 3. When the output source 17 drives the two baffles 16 to expand outward, the sealing rubber ring loses the blocking force, can fall between several limiting plates 6, and slide down to the two support plates 2 along the limiting plates 6. When the sealing rubber ring has fallen, the output source 17 promptly drives the two baffles 16 to reset to block and limit the upper layer of the sealing rubber ring to prevent it from falling.

[0033] As Figures 1 - 5 shown, as a preferred embodiment of the present invention, a collection box 4 is fixed on the filter screen 20, and two symmetrically arranged cover plates 11 are slidably installed on the top of the collection box 4. The positioning frame 18 is fixed above the collection box 4, and the cover plates 11 are slidably matched with the positioning frame 18. The two support plates 2 are respectively fixed on the two cover plates 11. A transmission component 12 is arranged on the positioning frame 18. When the dust removal is completed, the transmission component 12 drives the two cover plates 11 to move away from each other, and at the same time the two support plates 2 move away from each other, so that the dust-removed sealing rubber ring can fall into the open collection box 4.

[0034] In one case of this embodiment, the transmission component 12 includes: A gear 1201, which is coaxially and fixedly connected to a rotating shaft 1202, and the rotating shaft 1202 is rotatably installed on a positioning frame 18. The rotating shaft 1202 is driven to rotate by an external power source, and the number of the gears 1201 is two; and Two racks 1203 are respectively fixedly installed on two cover plates 11, and the two racks 1203 are respectively engaged with the two gears 1201, and the moving directions of the two racks 1203 are opposite.

[0035] Wherein, the external power source can be a motor assembly, or a gear assembly or a pulley assembly driven by a motor, as long as it can make the rotating shaft 1202 rotate. This embodiment does not make specific limitations here.

[0036] In the actual application of this embodiment, in the initial state, the two cover plates 11 are spliced, and the top of the collection box 4 is closed. At this time, the bottoms of the two support plates 2 are in contact with the bottom of the sealing rubber ring; after the dust removal is completed, the external power source drives the two rotating shafts 1202 to rotate, driving the two racks 1203 to move in the opposite direction. Then the two cover plates 11 move in the opposite direction, and the two support plates 2 move synchronously in the opposite direction. Then the dust-removed sealing rubber ring can freely fall. When the distance between the two cover plates 11 reaches the maximum, the top of the collection box 4 is open. At this time, the dust-removed sealing rubber ring can fall into the collection box 4 to realize the automatic collection of the dust-removed sealing rubber ring, and no other structural components are required to clamp and move during this process. The dust-free environment in the dust removal box 1 can ensure that the dust-removed sealing rubber ring will not be secondarily polluted.

[0037] As Figure 6 shown, as a preferred embodiment of the present invention, a dust-adhering layer 19 is provided on the inner wall of the collection box 4.

[0038] In the actual application of this embodiment, the setting of the dust-adhering layer 19 can perform secondary dust removal on the sealing rubber ring in the collection box 4 to ensure that the dust-removed sealing rubber ring will not be polluted again.

[0039] Working principle of the present invention: In the above embodiments of the present invention, a rapid dust removal device for a sealing rubber ring is provided. The sealing rubber ring is carried by two support plates 2. At this time, the ball 5 contacts the bottom of the sealing rubber ring. When the first air gun 13 outputs high-pressure air, the fan starts. The airflow can remove the dust on the surface of the sealing rubber ring, and the fan generates negative pressure during operation, so that the dust enters the dust collection box 21 through the filter screen 20 in sequence and is centrally recovered. During this process, the first air gun 13 blows several limiting plates 6 to rotate. At this time, the slider 7 slides on the slide rail 8, and at the same time, the rotation of the ball 5 drives the sealing rubber ring to rotate. In this way, the relative position between the support member (i.e., the ball 5) at the bottom of the sealing rubber ring and the sealing rubber ring can be changed, and at the same time, the relative position between the support member (i.e., the limiting plate 6) on the side of the sealing rubber ring and the sealing rubber ring can be changed. Each area on the sealing rubber ring can be in full contact with the airflow, which can avoid the problem of cleaning dead corners on the surface of the sealing rubber ring caused by support. After each area on the sealing rubber ring is fully dust-removed and then collected, it will not cause secondary contamination between the dust-removed sealing rubber rings due to cleaning dead corners, improving the speed and sufficiency of dust removal of the sealing rubber ring.

[0040] The above has described in detail one embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope covered by the patent of the present invention.
