Description

Technical Field

[0001] This invention relates to the field of corrugated roller technology, and more particularly to a dust and debris collection device for corrugated roller grinding machines. Background Technology

[0002] In the process of corrugated roll groove processing, the forming is not completed by rotating and engraving the entire roll body. Instead, a CBN / diamond grinding wheel is used to grind the standard flute shape segment by segment along the axial direction. Specifically, the grinding wheel has a profile section that matches the target flute shape. Under servo drive, it moves slowly along the axis of the corrugated roll, and the precision forming of a single groove is achieved through multiple micro-cuts. Under this condition, the corrugated roll itself is usually in a low-speed intermittent rotation or indexing positioning state. It only rotates one pitch after completing one groove before entering the processing cycle of the next groove. Since the grinding is carried out by grinding, a large amount of dust and debris is generated. Because the groove is formed by grinding, the debris generated at this time is usually fine particles. In order to avoid the influence of dust and debris, as well as the heat generated by grinding, coolant is often sprayed from a nozzle to collect dust and debris and cool the grinding wheel.

[0003] However, in the process of collecting dust and debris using jet cooling, the nozzle can only be positioned above or diagonally in front of the outer side of the grinding wheel due to the dominant space occupied by the grinding wheel itself, resulting in physical obstruction between the nozzle and the groove being formed. Even if the nozzle is responsive, its spray angle is still mainly "oblique scouring," making it difficult for the liquid jet to enter the groove opening perpendicularly or parallel to the groove axis. Furthermore, the grinding of the groove is a gradual process: from entry to exit, the chip generation location, heat concentration zone, and spatial opening are different at each stage. However, existing responsive nozzles mostly use rigid fixed connections, and the spray direction cannot be changed once set. The ejector cannot follow the state to enhance the chip removal effect, thereby improving the collection of dust and debris. At the same time, because the groove itself has a U-shaped closed structure and a small bottom curvature radius, the liquid flow is easily stagnated due to viscous resistance and surface tension. Since there is no guide channel or negative pressure auxiliary mechanism to guide the flow of the chip-containing liquid towards the chip discharge port, the particles are deposited at the bottom of the groove instead of being carried away. Summary of the Invention

[0004] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. The present invention provides a dust and debris collection device for corrugated roll grinding machines, which solves the problem that existing dust and debris collection methods often rely on spraying coolant. However, due to functional limitations, existing spraying devices cannot effectively remove dust and debris based on the forming characteristics of the corrugated roll grooves, resulting in some debris accumulating in the grooves and thus low debris collection efficiency.

[0005] The present invention employs the following technical solution: a dust and debris collection device for a corrugated roll grinding machine, comprising a multi-angle adaptive spraying mechanism, located beside the grinding wheel processing area and moving synchronously with the axial feed of the grinding wheel, for cooling and chip removal of dust and debris during the groove grinding process of the corrugated roll; the spray head is installed in a connecting frame via a first connecting rod and a second connecting rod, enabling it to move up and down and change angles, achieving pitch angle adjustment under controlled conditions; when the grinding wheel is in the groove cutting stage, the spray head is controlled to inject coolant forward at a low pitch angle to achieve pre-wetting and preliminary rinsing; when entering the exit stage, it is adjusted to a forward pushing mode, allowing the liquid flow to penetrate deep into the bottom of the groove and push the residual debris out, thereby achieving a time-space dual match between cooling behavior and groove forming process; The collection mechanism, located at the end of the grinding station, receives coolant containing fine particles and is used for efficient separation and centralized collection of suspended matter. The collection mechanism includes a separation tank. The aeration plate is arranged at the bottom of the separation tank and can release a large number of micron-sized bubbles into the coolant, causing fine particles to adhere to the surface of the bubbles to form "particle-bubble aggregates". Under the action of buoyancy, they float to the surface of the liquid to form a scum layer, thereby achieving the separation of particles and coolant for subsequent removal.

[0006] Furthermore, the separation chamber is arranged from top to bottom with a separation plate, an aeration plate, and an electrically controlled lifting rod. The aeration plate is connected to an external air pump via a connecting pipe, and the aeration plate and the separation plate are connected by an elastic clamping block. The movable end of the electrically controlled lifting rod passes through the aeration plate and connects to the separation plate. A stop block is provided on the movable end of the electrically controlled lifting rod. Friction plates are provided on both sides of the aeration plate. A friction surface is provided in a portion of the upper part of the separation chamber. A drain port is provided on the separation chamber. A scraper is provided above the separation chamber. The scraper moves back and forth via a drive assembly. A collection box is provided on the opposite side of the scraper.

[0007] Furthermore, the elastic clamping block is made of an elastic and deformable material, which deforms when squeezed, causing the separation plate to separate from the aeration plate.

[0008] Furthermore, the aeration port of the aeration plate is protruding and penetrates through the separation plate.

[0009] Furthermore, the multi-angle adaptive spraying mechanism includes a connecting frame with two through slots. A first connecting rod and a second connecting rod are respectively installed in the two through slots. The first connecting rod and the second connecting rod are connected to the head and tail of the spray head, respectively. A contact limiting block is installed in one of the through slots. The contact limiting block moves up and down via a second electric telescopic rod. A squeezing block is installed in the other through slot. The squeezing block is connected to the contact limiting block. The first connecting rod and the connecting frame move up and down via the first electric telescopic rod.

[0010] Furthermore, the first connecting rod and the spray head are rotatably connected, and the connection point is located in the head area.

[0011] Furthermore, the head section of the spray head is made of a soft material, and an elastic shrink sleeve is provided on the outside of this section. A spring abutment block is provided on the outside of the elastic shrink sleeve. The spring abutment block and the elastic abutment block are in inclined contact, and a portion of the outer surface of the spring abutment block is inclined. This inclined surface is in contact with the inclined surface of the extrusion block.

[0012] Furthermore, both the first and second electric telescopic rods move synchronously with the grinding assembly via a controller.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: Firstly, through the multi-angle adaptive spraying mechanism, when the sprayer moves synchronously with the grinding wheel to reduce dust at the grinding position, the multi-angle adaptive mechanism will adjust the spraying state according to different processing steps. That is, the mechanism should be able to switch the spraying mode at different processing stages—such as using low-angle forward injection during the entry phase and switching to forward pushing during the exit phase—thereby achieving a time-space dual match between cooling behavior and groove forming process. At the same time, during the spraying process, it can penetrate deep into the bottom of the groove, effectively avoiding the grinding wheel blocking the spraying position, thereby discharging the debris located at the bottom of the groove for subsequent collection. Secondly, by setting up a collection mechanism, fine particles in the coolant entering the collection tank can be effectively collected. It should be noted that this structure provides better collection than a simple filter screen and avoids clogging. As described in the background, existing debris consists of fine particles commonly found during grinding. These particles are small, and filtering with a filter screen results in small pores, leading to poorer flow and increased clogging. The collection mechanism in this invention eliminates the need for filtration, effectively preventing filter clogging. Furthermore, because the particles are small, they are essentially suspended in the coolant. This solution effectively collects these suspended particles. The general principle is as follows: injecting a large number of micron-sized bubbles into the debris-containing coolant → bubbles adhere to the particle surface → forming a "particle-bubble aggregate" → with an overall density less than water → floating to the surface to form scum → which is then scraped off and collected, thereby improving filtration and separation and increasing the collection rate.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0019] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The following is combined with Figures 1 to 9 As shown, this embodiment of the invention provides a dust and debris collection device for a corrugated roll grinding machine, including a multi-angle adaptive spraying mechanism 2, which is located beside the grinding wheel processing area and moves synchronously with the axial feed of the grinding wheel. It is used to cool and remove dust and debris generated during the groove grinding process of the corrugated roll. The spray head 25 is installed in the connecting frame 21 via a first connecting rod 22 and a second connecting rod 28. The first connecting rod 22 and the second connecting rod 28 allow it to move up and down and change angles, achieving controlled pitch angle adjustment. When the grinding wheel is in the groove entry stage, the spray head 25 is controlled to inject coolant forward at a low pitch angle to achieve pre-wetting and initial rinsing. When entering the exit stage, it is adjusted to a forward pushing mode, allowing the liquid flow to penetrate deep into the bottom of the groove and push out residual debris, thereby achieving a time-space dual match between cooling behavior and the groove forming process. The collection mechanism 3, located at the end of the grinding station, receives coolant containing fine particles and is used for efficient separation and centralized collection of suspended matter. The collection mechanism 3 includes a separation tank 31. The aeration plate 37 is arranged at the bottom of the separation tank 31 and can release a large number of micron-sized bubbles into the coolant, causing fine particles to adhere to the surface of the bubbles to form "particle-bubble aggregates". Under the action of buoyancy, they float to the surface of the liquid to form a scum layer, thereby achieving the separation of particles and coolant for subsequent removal.

[0023] During operation, it is necessary to further explain that the particulate matter generated during processing is divided into large particles and small particles. Due to their own mass, large particles will sink to the top of the separation plate 35, while suspended particles can be removed by the principle of air bubbles. Therefore, this collection mechanism 3 can remove both suspended and large particles. At the same time, the collection box 32 is equipped with a drain port that can be opened manually, and a filter screen is installed at the drain port.

[0024] Specifically, the separation box 31 is arranged from top to bottom as follows: a separation plate 35, an aeration plate 37, and an electrically controlled lifting rod 36. The aeration plate 37 is connected to an external air pump through a connecting pipe 38. The aeration plate 37 and the separation plate 35 are connected by an elastic clamping block 351. The movable end of the electrically controlled lifting rod 36 passes through the aeration plate 37 and connects to the separation plate 35. A stop block is provided on the movable end of the electrically controlled lifting rod 36. Friction plates 371 are provided on both sides of the aeration plate 37. A friction surface is provided in a portion of the upper part of the separation box 31. A drain port is provided on the separation box 31. A scraper 33 is provided above the separation box 31. The scraper 33 moves back and forth through a drive assembly 34. A collection box 32 is provided on the opposite side of the scraper 33.

[0025] Specifically, the aeration port of the aeration plate 37 is protruding and penetrates the separation plate 35.

[0026] During operation, the particles can be deposited on the surface of the separation plate 35 without affecting the aeration process. At the same time, since the aeration plate 37 and the separation plate 35 can move relative to each other, the surface of the separation plate 35 can be transformed into a plane when removing the sediment, and the scraper plate 33 can be used for simultaneous scraping.

[0027] Specifically, the multi-angle adaptive spraying mechanism 2 includes a connecting frame 21 with two through slots. A first connecting rod 22 and a second connecting rod 28 are respectively installed in the two through slots. The first connecting rod 22 and the second connecting rod 28 are connected to the head and tail of the spray head 25, respectively. One through slot has a contact limiting block 23 located directly below the first connecting rod 22. The contact limiting block 23 moves up and down via a second electric telescopic rod 26. The other through slot has a squeezing block 24 connected to the contact limiting block 23. The spray head 25 and the connecting frame 21 move up and down via a first electric telescopic rod 27. It should also be noted that a torsion spring is installed between the second connecting rod 28 and the head, providing resistance during rotation.

[0028] During operation, in order to ensure the rotation angle of the spray head 25 and the positional change after rotation, it is necessary to control the connection position between each connecting rod and the spray head 25.

[0029] Specifically, the first connecting rod 22 and the spray head 25 are rotatably connected, and the connection point is located in the head area. It should be noted that since the spray head 25 rotates around the first connecting rod 22, the first electric telescopic rod 27, when pressing the spray head 25, actually uses a sliding sleeve fitted on the spray head 25. The sliding sleeve is equipped with a pivot, which allows the spray head 25 and the first electric telescopic rod 27 to slide and rotate, avoiding structural interference. At the same time, when the sliding sleeve is fitted at the position of the spray head 25 pipe, the wrapping angle of the sliding sleeve is greater than 180°, creating a notch to ensure that the second connecting rod 28 can be connected to the spray head 25. In addition, the second connecting rod 28 uses a spring component, so when the spray head 25 needs to deflect, it will not interfere with the deflection of the spray head 25.

[0030] Specifically, the head section of the spray head 25 is made of a soft material, that is, the connection area between the end and the tail of the spray head 25 is made of a soft material, so that its inner diameter can change when it is squeezed. An elastic shrink sleeve 252 is provided outside this part of the area, and a spring abutment block 251 is provided outside the elastic shrink sleeve 252. The spring abutment block 251 and the elastic shrink sleeve 252 are in inclined contact, and a part of the outer surface of the spring abutment block 251 is inclined, which is in contact with the inclined surface of the extrusion block 24.

[0031] Specifically, the first electric telescopic rod 27 and the second electric telescopic rod 26 both move synchronously with the grinding assembly 1 via a controller.

[0032] During operation, it should be noted that the depth of the grooves of different corrugated rollers will vary during the grinding process. Therefore, the spray position after the spray head 25 exits will also change in depth. At this time, the position of the extrusion block 24 can be controlled by the second electric telescopic rod 26, which drives the extrusion block 24. The displacement of the second electric telescopic rod 26 is related to the processing depth, while the first electric telescopic rod 27 is related to the processing state of the grinding assembly 1.

[0033] Working principle: During use, the grinding component 1 drives the multi-angle adaptive mechanism to move, while the collecting mechanism 3 is located at the outlet of the machine tool, and the outlet is connected to the top of the separation box 31. During the grinding process, the multi-angle adaptive mechanism moves up and down accordingly. Since there is a small angle between the spray head 25 and the grinding head, the coolant directly acts on the grinding head and the workpiece, ensuring good cooling. When one side is finished grinding, the grinding assembly 1 is raised. During this raising, the first electric telescopic rod 27 begins to operate, its movable section moving downwards and causing the spray head 25 to move downwards as a whole. As it continues to move downwards, the first connecting rod 22 of the spray head 25 is stopped by the abutment and restraint block 23, preventing its head from moving downwards. However, its tail continues to move due to the influence of the first electric telescopic rod 27. Therefore, the angle of the spray head 25 changes, meaning the angle between the spray head 25 and the grinding head increases. This results in a change in the angle between the spray head 25 and the workpiece. As the angle decreases, the sprayed coolant is more directly sprayed between the grooves, generating thrust. During the deflection process, the spring contact block 251 contacts the extrusion block 24, causing the spring contact block 251 to move towards the elastic contraction sleeve 252, thereby compressing the elastic contraction sleeve 252 and reducing the inner diameter of the spray head 25. Since the water flow rate remains constant, the water pressure increases when the pipe diameter changes, facilitating the ejection of particles. During use, the groove depth changes. To ensure the particle ejection effect, i.e., to maintain the angle between the processing low point and the spray head 25 within a certain range, the deflection position needs to be adjusted. Based on the processing situation, the second electric telescopic rod 26 is controlled to adjust the position of the contact limiting block 23 and the extrusion block 24, thus changing the shape and position of the spray head 25. The discharged particles enter the separation chamber 31 through the machine tool's drainage outlet. Since the separation chamber 31 is equipped with an aeration component, the particles suspended in the coolant are floated up by aeration. At this point, the drive component 34 is controlled to move the scraper plate 33. This drive component 34 can be a motor-driven screw rotation, which in turn moves the scraper plate 33. The scraper plate 33 pushes the particles on the liquid surface into the collection box 32, thus removing the surface layer. It should also be noted that some larger particles will sink, falling onto the surface of the separation plate 35. When a large amount of deposited particles have been removed, the suspended particles are removed. Then, the drainage outlet on the separation chamber 31 is activated, and the electrically controlled lifting rod 36 is activated, which moves the separation plate... As the separation plate 35 rises, the aeration plate 37 is connected to the separation plate 35 by the elastic clamping block 351. Therefore, the aeration plate 37 also moves upwards synchronously. During the lifting process, the coolant inside is gradually discharged. When it reaches a certain height, the friction plates 371 on both sides of the aeration plate 37 align with the friction points on the separation box 31. At this point, the frictional resistance is greater than the clamping force of the elastic clamping block 351, causing the elastic clamping block 351 to deform. That is, the position of the aeration plate 37 remains unchanged, and the separation plate 35 continues to rise until it reaches the bottom surface of the scraper plate 33. However, because the aeration plate 37 has a protrusion, the relative movement between the separation plate 35 and the aeration plate 37 causes the top surface of the protrusion to be flush with the upper surface of the separation plate 35. At this point, the scraper plate 33 scrapes away the deposited particles on the separation plate 35, thus achieving the dual removal of suspended matter and sediment.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
