Description

Technical Field

[0001] The utility model relates to the field of profile processing, in particular to a profile corner cleaning device. Background Art

[0002] There are various methods for securing the glass in plastic profile windows and doors, depending on the specific window type, design requirements, and installation environment. For windows and doors requiring a tight seal, such as those using insulating glass, rubber strips are used. These strips are inserted into the groove between the profile frame and the glass, ensuring a tight fit. Sealant or other suitable sealing material is then injected to further secure the glass and enhance the seal. To ensure stable force between the glass and the profile, the weld seams on the inside of the profile frame must be cleaned. Traditionally, this cleaning method uses an end mill to mill the inclined weld seams to ensure a good fit between the glass and the profile.

[0003] However, for profiles with glue grooves, in order to ensure sealing performance, the contact area between the glass and the glue grooves needs to be as large as possible. To this end, the welds at the welding positions need to be completely cleaned so that the edge of the glass can approach the inner facade of the profile body on one side of the glue groove. A Chinese patent (publication number CN102380924A) discloses a plastic door and window rubber strip groove and inner facade weld cleaning machine, which uses a milling cutter and a slotting knife to clean the welds vertically. The grinding path formed by the milling cutter when rotating is circular. When cleaning the welds, it is impossible to reach the welds near the corners of the inner facade, resulting in cleaning residues. When the glass is placed, it is blocked by the welds and cannot be completely flush with the glue grooves. The slotting knife used is blocked by other structures on the profile and it is difficult to reach the corners of the inner facade from the vertical direction. As a result, the welds at the corners of the inner facade are difficult to be effectively cleaned, affecting the gluing effect and the glass installation effect. As a result, the contact area between the glass and the glue groove is difficult to meet the requirements, affecting the sealing and stability. Utility Model Content

[0004] The purpose of this utility model is to address the defects of the existing technology and provide a profile corner cleaning device, which uses a pushing mechanism to drive a scraper and a guide roller to move along the profile glue coating groove, and moves upward along the axis of the profile to remove the weld. The front end of the scraper is parallel to the inner facade of another profile, and penetrates into the corner position of the inner facade for cleaning. The cleaning range of the scraper can cover the distribution position of the weld, and can move vertically after removing the weld, thereby meeting the cleaning needs of the weld and improving the weld cleaning efficiency.

The lifting mechanism is installed on the base frame, and a pad matching the profile is provided on the base frame. The pushing mechanism includes a pushing support plate, a scraper frame, a scraper and a guide roller. The pushing support plate is installed on the output end of the lifting mechanism through the pushing frame, and the scraper frame is installed on the pushing support plate through a sliding pair. The pushing drive element is connected to the scraper frame to drive the scraper frame to run along the sliding pair, and the running direction is parallel to the profile matched by the pad; the scraper and guide rollers are respectively installed on the scraper frame and are spaced apart in the running direction of the sliding pair, and a space for accommodating the profile is formed between the scraper and the pad.

[0007] Furthermore, the scraper includes a first scraper and a second scraper, and in the moving direction of the output end of the lifting mechanism, the working end of the first scraper and the working end of the second scraper are staggered.

[0008] Furthermore, the end of the scraper away from the guide roller is a working end, and the working end matches the glue coating groove of the profile.

[0009] Furthermore, the sliding pair includes a matching pushing guide rail and a pushing guide block, the pushing guide block is mounted on the pushing support plate, the pushing guide rail is mounted on the blade frame, and the pushing guide rail slides along its axial direction relative to the pushing guide block.

[0010] Furthermore, a guide rod is installed on the base frame, the axis of the guide rod is distributed along a direction parallel to the running direction of the output end of the lifting mechanism, and the guide rod is slidably matched with a guide hole preset on the pushing frame.

[0011] Furthermore, a clamping mechanism is provided on the base frame, which includes a clamping drive, a pressure plate frame and a pressure plate. The pressure plate frame is installed on the base frame through the clamping drive, and the pressure plate and the pad are arranged relatively spaced apart. The pressure plate is installed on the pressure plate frame to operate under the drive of the clamping drive.

[0012] Furthermore, the pressing plate frame is located between the pushing frame and the base frame, and a guide hole that is slidably matched with the guide rod is provided on the pressing plate frame.

[0013] Furthermore, a backing plate is installed on the base frame, and the backing plate and the cushion block are spaced apart in the plane where the top surface of the base frame is located.

[0014] Furthermore, the wheel axle of the guide roller is connected to the adjusting shaft, and the adjusting shaft is installed on the scraper frame so that the guide roller is installed on the scraper frame.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are:

[0017] (1) In order to solve the problem that the welds at the inner corners of the profile frame cannot be thoroughly cleaned by using a vertical milling cutter, a pushing mechanism is used to drive the scraper and the guide roller to move along the profile glue groove, and the welds are removed by moving upward along the axis of the profile. The front end of the scraper is parallel to the inner surface of the other profile, and penetrates into the corner position of the inner surface for cleaning.

[0027] In a typical embodiment of the present invention, Figure 1-Figure 5 As shown, a profile corner cleaning device is proposed.

[0028] like Figure 1 As shown, when cleaning the welds at the welding corners of the profiles to form the profile frame 5, a vertical milling cutter is often used for cleaning. The vertical milling cutter cleaning range 4 is a circle, and the corner position where the weld 1 to be cleaned is located is distributed at right angles, making it difficult for the vertical milling cutter cleaning range to completely cover the weld 1 to be cleaned. Only part of the weld can be cleaned, resulting in residual welds 3 deep in the corners. Although the size of the glass is smaller than the frame size surrounded by the inner facade 2 of the profile frame 5, for the profile with the glue groove, the corner position of the glass should be as close to the corner position of the profile frame 5 as possible, that is, the edge of the glass corner should fit as closely as possible to the inner facade 2 of the profile frame 5, thereby increasing the contact range between the glass glue and the glass. The residual weld 3 will make it difficult for the glass corner position to be close to the inner facade 2 of the profile, so that the glass is lifted by the residual weld 3, and the glass cannot fit the edge of the glue groove. Based on this, this embodiment provides a profile cleaning device, the scraper 9 moves axially along a profile frame 5, and the front end of the scraper 9 can form a scraper cleaning range 8 that fits the inner facade 2 of the profile, such as Figure 2 As shown, on the scraper cleaning path 7, the scraper 9 cleaning area can cover the weld 1 to be cleaned, and can also remove the weld 1 to be cleaned close to the facade, thereby reducing the residual weld 3, so that the angular position of the glass can match the angular position of the profile frame 5, avoiding the residual weld 3 to lift the glass, and the glass surface can fit with the edge of the glue groove, improving the sealing performance and the coverage range of the glass glue, thereby ensuring the sealing and stability.

[0029] like Figure 3As shown, a profile corner cleaning device primarily comprises a base frame 19, a lifting mechanism 20, a clamping mechanism, and a pushing mechanism. The base frame 19 serves as the supporting structure for the entire device, ensuring its stability and reliability. The lifting mechanism 20 is mounted on the base frame 19 and is used to adjust the height of the pushing mechanism 11 to accommodate profiles of varying heights or different cleaning requirements. The pushing mechanism 11 comprises a push support plate 12, a blade frame 13, a blade 9, and a guide roller 10. The push support plate 12 is mounted to the output end of the lifting mechanism 20 via a push frame 21, serving as a mounting platform for the blade frame 13 and guide roller 10. The blade frame 13 is mounted to the push support plate 12 via a sliding pair and can move along the sliding pair driven by a push drive element. The sliding pair operates parallel to the profile to which the pad 14 is attached, ensuring that the blade 9 can move axially along the profile. The blade 9 is mounted on the blade frame 13, with its front end parallel to the inner facade 2 of the other profile, enabling it to penetrate into a corner of the inner facade 2 for cleaning. The design of the scraper 9 ensures that the cleaning range can cover the distribution position of the weld. The guide roller 10 is also installed on the scraper frame 13, spaced apart from the scraper 9, and is used to guide the scraper 9 to move along the profile during the cleaning process, maintaining the stability and accuracy of the cleaning path.

[0030] like Figure 4 As shown, a pad 14 is also provided on the base frame 19. The pad 14 is provided on the base frame 19 to match the shape and size of the profile and to form a space for accommodating the profile together with the scraper 9 and the guide roller 10. The function of the pad 14 is to support the profile so that the scraper 9 can accurately align with the weld for cleaning.

[0031] The lifting mechanism 20 can use linear drive elements or components such as electric cylinders, air cylinders, and oil cylinders to drive the pushing frame 21 to adjust the distance relative to the base frame 19. In this embodiment, the base frame 19 is placed horizontally, and the output end of the lifting mechanism 20 runs in a direction perpendicular to the base frame 19, that is, it runs vertically. The lifting mechanism 20 drives the pushing frame 21 and its connected pushing support plate 12 and scraper frame 13 to adjust the height relative to the base frame 19.

[0032] During operation, the pushing mechanism 11 drives the scraper 9 and the guide roller 10 to move along the profile glue coating groove, and moves upward along the axis of the profile to scrape off the weld. The front end of the scraper 9 is parallel to the inner facade 2 of the other profile, and penetrates into the angular position of the inner facade 2 for cleaning. The scraper cleaning range 8 can cover the distribution position of the weld. After scraping off the weld, the scraper 9 can be driven to lift up by the lifting mechanism 20, so that the scraped weld is brought down and the residual weld 3 is thoroughly cleaned, thereby meeting the cleaning needs of the weld and improving the weld cleaning efficiency.

[0033] The pushing support plate 12 of the pushing mechanism 11 can connect the lifting mechanism 20 and the scraper frame 13 to provide a stable pushing platform. The sliding pair ensures that the scraper frame 13 can move smoothly and accurately along the axial direction of the profile.

[0034] In this embodiment, Figure 5 As shown, the sliding pair includes a cooperating push guide rail 22 and a push guide block. The push guide block is mounted on the push support plate 12, and the push guide rail 22 is mounted on the blade frame 13. The push guide rail 22 slides axially relative to the push guide block. The push guide block can be a guide block with a dovetail groove, and the push guide rail can be a guide rail with a dovetail slider. When the push guide block and push guide rail 22 are engaged, the axis of the push guide rail is parallel to the top surface of the base frame 19, and the direction in which the push guide rail moves the blade frame 13 is parallel to the top surface of the base frame 19. This ensures that the blade frame 13 can move smoothly and accurately along the axial direction of the profile.

[0035] The blade frame 13 is used to carry the blade 9 and guide rollers 10 and is driven by a push drive element. The push drive element can be a linear drive element or component such as an electric cylinder, a pneumatic cylinder, or an oil cylinder to drive the blade frame 13 to move relative to the push support plate 12, thereby driving the blade 9 to complete the action of scraping the weld 1 to be cleaned.

[0036] The shape and angle of the scraper 9 adapt to the profile's gluing groove to remove welds. The guide roller 10 reduces friction and guides the scraper 9 along the profile. The pad 14 can be customized to the profile shape to ensure stable placement of the profile.

[0037] In this embodiment, the scraper 9 adopts a double-edged structure. Figure 5 As shown, the scraper 9 includes a first scraper 9 and a second scraper 9. The working ends of the first scraper 9 and the second scraper 9 are staggered in the direction of movement of the output end of the lifting mechanism 20. To cope with the complex weld shapes found in the gluing tank of the profile, particularly the flanged edges of the inner ring of the gluing tank, the first scraper 9 can abut the flanged edge of the gluing tank, while the second scraper 9 extends into the gluing tank, creating a height difference between the two. This adapts to the weld shape, improves the cleaning effect, and reduces damage to the profile caused by the scrapers 9.

[0038] The end of the scraper 9 away from the guide roller 10 is designed as the working end, which extends beyond the range of the scraper frame 13 and can match the glue groove of the profile. At the same time, the main body of the scraper frame 13 can contact the weld 1 to be cleaned in advance, ensuring that the scraper 9 can accurately cut into the weld for cleaning.

[0039] Because the overall structure of the blade frame 13, sliding pair, and push support plate 12 is relatively complex, guide rods are mounted on the base frame 19 to ensure support for the push mechanism 11. The axes of the guide rods are arranged parallel to the direction of travel of the output end of the lifting mechanism 20. The push frame 21 is provided with guide holes that slide with the guide rods, enhancing the stability of the push mechanism 11 and preventing it from shifting during movement.

[0040] In order to keep the profile stable when cleaning the weld, a clamping mechanism is also provided, such as Figure 4 and Figure 3 As shown, the pressing mechanism includes a pressing drive 17, a pressing plate frame 18, and a pressing plate 15. The pressing plate frame 18 is mounted on a base frame 19 via the pressing drive 17. The pressing plate 15 is spaced relative to the spacer 14. Driven by the pressing drive 17, the pressing plate 15 can press the profile, ensuring that the profile does not move or deform during the cleaning process.

[0041] The pressing plate frame 18 is located between the pushing frame 21 and the base frame 19 and is provided with a guide hole that slides with the guide rod. This ensures that the clamping mechanism remains stable when clamping the profile and does not interfere with the operation of the pushing mechanism 11. The clamping drive 17 can be a linear drive element or component such as an electric cylinder, an air cylinder, or an oil cylinder to drive the pressing plate frame 18 and the pressing plate 15 relative to the pad 14, thereby changing the spacing between the pressing plate 15 and the pad 14, so that the pressing plate 15 can stably constrain the profile frame 5 of the weld 1 to be cleaned between the pad 14 and the pressing plate 15.

[0042] like Figure 4 As shown, a backing plate 16 is mounted on the chassis 19, and the backing plate 16 is spaced apart from the pad 14. The backing plate 16 serves to provide additional side support to ensure that the profile can maintain the correct position during the cleaning process.

[0043] like Figure 5 As shown, the axle of the guide roller 10 is mounted to the blade frame 13 via an adjustment shaft. The adjustment shaft is eccentrically positioned and docked with the axle. Rotating the adjustment shaft changes the height difference between the axle and the plane of the blade 9. The working depth of the guide roller 10 can be adjusted as needed, while ensuring that the blade 9 moves along the correct path and avoids deviation in the depth direction.

[0044] A propulsion mechanism 11 drives the scraper 9 and guide roller 10 along the profile's gluing trough, removing welds axially from the profile. The front end of the scraper 9 is parallel to the inner facade 2 of the other profile, allowing it to penetrate the corners of the inner facade 2 for thorough cleaning, covering the entire weld distribution. By mounting two offset scrapers 9 on the scraper frame 13, the scraper frame adapts to the complex weld geometry formed by the gluing trough at the corners of the profile frame 5, improving weld cleaning effectiveness.

[0045] The height difference of the wheel axles of the guide rollers 10 is adjusted to control the working depth of the scraper 9 , while ensuring that the scraper 9 moves along the correct path to reduce damage to the profile caused by the scraper 9 .

[0046] The coordination of the sliding pair, guide rod, and guide hole, as well as the addition of a clamping mechanism, enhances the stability and cleaning efficiency of the push mechanism 11. Through multiple optimizations and innovative designs, the cleaning effect and adaptability of the profile corner cleaning device have been significantly improved, providing a more efficient and reliable solution for the profile processing industry.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
