Description

Technical Field

[0001] This invention relates to the field of door and window manufacturing technology, and in particular to a roller pressing and feeding device for sealing strips used in PVC profiles. Background Technology

[0002] Windows are an indispensable structure in building decoration, typically consisting of a frame and glass. PVC profiles, as a building material, are often used to form the frame. With the development of energy-efficient doors and windows, the sealing strips used with PVC profiles are also being upgraded. Currently, the mainstream sealing strip material on the market is rubber-based. Compared to traditional PVC sealing strips, it has significant advantages in terms of heat insulation, cold resistance, and aging performance, making it the preferred product for doors and windows in the industry. However, both silicone-based and EPDM rubber-based sealing strips have different polarities than PVC, making it difficult to achieve co-extrusion of the sealing strips online.

[0003] Therefore, after the profiles are produced or during the processing of doors and windows, it is necessary for personnel to manually press the rubber strips into the rubber strip openings of the profiles. However, this manual installation method not only makes the labor intensity of the workers high, but also has the problem of low production efficiency. Summary of the Invention

[0004] In view of the above problems, the present invention provides a roller pressing and feeding device for sealing strips for PVC profiles.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A roller pressing and guiding device for sealing strips for PVC profiles is provided, which is installed at the output end of a profile extruder. It includes a mounting base, a mounting frame on the mounting base, and a first platform and a second platform vertically slidably mounted on the mounting frame. The first platform is located below the second platform, and a transport channel for the profile and sealing strip to pass through is formed between the first platform and the second platform. The first platform is provided with a material supporting mechanism for supporting the profile, and the second platform is provided above the material supporting mechanism for pressing down the sealing strip and embedding it into the profile sealing strip opening during profile transport. The mounting frame is provided with a first driving member for driving the first platform to move and a second driving member for driving the second platform to move.

[0007] Furthermore, the material support mechanism includes two parallel lifting rollers, which are horizontally rotatably mounted on one side of the first platform. The axes of the lifting rollers are perpendicular to the transport direction of the profile, and the lifting rollers are in rolling contact with the bottom of the profile.

[0008] Furthermore, the pressing mechanism includes a first pressing roller, which is parallel to the lower supporting roller and rotatably mounted on the second platform. The first pressing roller is located above the rubber strip opening of the profile, and the first pressing roller makes rolling contact with the sealing rubber strip.

[0009] Furthermore, a first mounting plate is slidably installed on the second platform at the feed end of the transport channel along the profile transport direction. The first mounting plate is provided with a guide mechanism, which includes a guide block. The guide block is vertically slidably installed on one side of the first mounting plate. A guide hole for the sealing strip to pass through is opened on one side of the guide block along the profile transport direction. A guide strip for inserting into the profile sealing strip opening is provided at the bottom of the guide block. A third driving member is provided on the second platform for driving the first mounting plate to move. A first limiting member is provided on the first mounting plate for restricting the movement of the guide block.

[0010] Furthermore, a second mounting plate is slidably disposed on the second platform in a direction parallel to the axis of the lifting roller, the first pressing roller is rotatably disposed on the second mounting plate, and a fourth driving member is provided on the second platform for driving the second mounting plate to move.

[0011] Furthermore, the mounting base includes two parallel horizontal shafts, with base beams connected to both ends of the two horizontal shafts. The mounting bracket is slidably mounted on the horizontal shafts along their axial direction, and the mounting bracket is provided with a second limiting member for restricting its movement relative to the horizontal shafts.

[0012] Furthermore, the first driving component includes a first screw, a first through hole at the bottom of the mounting bracket, and a first threaded hole at the bottom of the first platform that matches the first screw. The first screw passes through the first through hole and is threaded into the first threaded hole. The second driving component includes a second screw, a second through hole at the top of the mounting bracket, and a second threaded hole at the top of the second platform that matches the size of the second screw. The second screw passes through the second through hole and is threaded into the second threaded hole. The third driving component includes a third screw, a third through hole extending along the profile transport direction on the first mounting plate, and a third threaded hole of a size matching the third screw on the side of the second platform near the first mounting plate. The third screw passes through the third through hole and is threaded into the third threaded hole. The fourth driving component includes a fourth screw, a fourth through hole extending along a direction parallel to the axis of the first pressure roller on the second platform, and a fourth threaded hole adapted to the fourth screw on the second mounting plate. The fourth screw passes through the fourth through hole and is threaded into the fourth threaded hole.

[0013] Furthermore, the first limiting component includes a limiting bolt, and a vertical strip hole is provided through the guide block on the side away from the first mounting plate. A fifth threaded hole adapted to the limiting bolt is provided on the first mounting plate. After the limiting bolt passes through the strip hole, it is threaded into the fifth threaded hole. The second limiting component includes a fifth screw and a pressure plate. The pressure plate is located at the bottom of the mounting frame. Both the mounting frame and the pressure plate are provided with a sliding groove for the horizontal shaft to pass through. The inner wall of the sliding groove slides in contact with the outer wall of the horizontal shaft, and a gap is left between the mounting frame and the pressure plate. One end of the pressure plate is connected to the mounting frame, and the other end of the pressure plate is vertically provided with a fifth through hole for the fifth screw to pass through. A sixth threaded hole with a size adapted to the fifth screw is provided on the mounting frame. After the fifth screw passes through the fifth through hole, it is threaded into the sixth threaded hole.

[0014] Furthermore, a second pressing roller is rotatably mounted on the side of the first pressing roller away from the guide block on the second mounting plate. Gears are coaxially mounted on the shafts of both the first and second pressing rollers, and belts meshing with the gears are wound around the two gears. The diameter of the gear on the first pressing roller is smaller than the diameter of the gear on the second pressing roller, so that the linear velocity of the first pressing roller is greater than that of the second pressing roller.

[0015] Furthermore, both the first and second pressing rollers have anti-slip textures on their outer walls.

[0016] The beneficial effects of this invention are as follows: When the profile moves to the feeding end of the transport channel, the operator needs to manually move one end of the sealing strip to the feeding end of the transport channel along the profile transport direction, and position the sealing strip directly above the profile's sealing strip opening. The material support mechanism can support the bottom of the profile, and the pressing mechanism can press down to abut against the sealing strip. Under the pressure of the pressing mechanism, the sealing strip will embed into the profile's sealing strip opening and abut against the profile. Since the profile is driven to move by the extruder, friction is generated between the sealing strip and the profile, allowing it to move with the profile while being pressed down to embed into the profile's sealing strip opening. After the profile has completely passed through the transport channel, the sealing strip can be cut along the end of the profile. This eliminates the need for the operator to manually press the sealing strip into the sealing strip opening, thus reducing the operator's labor intensity and improving production efficiency.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This application discloses a roller-pressing and introducing device for sealing strips used in PVC profiles, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a mounting base 1, a mounting frame 2 on the mounting base 1, and a first platform 3 and a second platform 4 vertically slidably mounted on the mounting frame 2. The first platform 3 is located below the second platform 4, and a transport channel 21 is formed between the first platform 3 and the second platform 4 for the profile 10 and the sealing strip to pass through. A material-supporting mechanism 5 for supporting the profile 10 is mounted on the first platform 3, and a material-pressing mechanism 6 for pressing down the sealing strip and embedding it into the sealing strip opening 101 of the profile 10 during transport is mounted on the second platform 4 above the material-supporting mechanism 5. A first driving member for moving the first platform 3 and a second driving member for moving the second platform 4 are mounted on the mounting frame 2.

[0025] This application discloses a roller-pressing and feeding device for sealing strips used in PVC profiles, which is installed on an operating platform and located at the output end of the profile extruder. Figure 2The arrow in the diagram indicates the direction of movement of the profile 10. In this embodiment, starting the extruder drives the profile 10 from the output end of the extruder into the transport channel 21. When the profile 10 moves to the feed end of the transport channel 21, the operator needs to manually move one end of the sealing strip to the feed end of the transport channel 21 along the transport direction of the profile 10, and position the sealing strip directly above the strip opening 101 of the profile 10. The first driving member drives the first platform 3 to move so that the material support mechanism 5 can support the bottom of the profile 10; the second driving member drives the second platform 4 to move so that the pressing mechanism 6 can press down and abut against the sealing strip. Under the pressure of the pressing mechanism 6, the sealing strip will embed into the strip opening 101 of the profile 10 and abut against the profile 10. Since the profile 10 is driven to move by the extruder, friction is generated between the sealing strip and the profile 10, allowing it to move together with the profile 10 while being pressed down and embedded into the strip opening 101. After the profile 10 has completely passed through the transport channel 21, the sealing strip can be cut along the end of the profile 10. Compared with the traditional installation method, the sealing strip roller introduction device for PVC profile 10 of this application eliminates the need for workers to manually press the sealing strip into the sealing strip opening 101, which reduces the labor intensity of workers and improves production efficiency.

[0026] Specifically, the material support mechanism 5 includes two parallel lifting rollers, which are horizontally rotatable on one side of the first platform 3. The axes of the lifting rollers are perpendicular to the transport direction of the profile 10, and the lifting rollers are in rolling contact with the bottom of the profile 10.

[0027] In this embodiment, the pressing mechanism 6 presses the sealing strip down and embeds it into the sealing strip opening 101 of the profile 10, generating friction between the material supporting mechanism 5 and the bottom of the profile 10. By rotating the lifting roller on the first platform 3, it can rotate with the profile 10, preventing excessive obstruction at the bottom of the profile 10 and thus avoiding wear.

[0028] Specifically, the pressing mechanism 6 includes a first pressing roller 61, which is parallel to the lower supporting roller and rotatably mounted on the second platform 4. The first pressing roller 61 is located above the rubber strip opening 101 of the profile 10, and the first pressing roller 61 makes rolling contact with the sealing rubber strip.

[0029] In this embodiment, when the profile 10 moves to the feeding end of the transport channel 21, the operator can move one end of the sealing strip along the transport direction of the profile 10 to between the profile 10 and the first pressure roller 61. Since the sealing strip is a flexible material, it can be squeezed into the space between the profile 10 and the first pressure roller 61. The sealing strip is subjected to the squeezing and traction forces of the profile 10 and the first pressure roller 61, allowing it to move with the profile 10. At the same time, the sealing strip is also embedded in the sealing strip opening 101 of the profile 10 under the pressure of the first pressure roller 61.

[0030] Furthermore, a first mounting plate 7 is slidably mounted on the second platform 4 at the feed end of the transport channel 21 along the transport direction of the profile 10, and a guide mechanism 8 is mounted on the first mounting plate 7. (Refer to...) Figure 4 and Figure 5 The guiding mechanism 8 includes a guide block 81, which is vertically slidably disposed on one side of the first mounting plate 7. A guide hole 811 is provided on one side of the guide block 81 along the transport direction of the profile 10 for a sealing strip to pass through. A guide strip 812 is integrally fixed to the bottom of the guide block 81 for insertion into the sealing strip opening 101 of the profile 10. A third driving component is installed on the second platform 4 to drive the first mounting plate 7 to move, and a first limiting component is installed on the first mounting plate 7 to restrict the movement of the guide block 81.

[0031] In this embodiment, to improve the stability of the first mounting plate 7 during movement, a guide rod is also connected between the second platform 4 and the first mounting plate 7. A third driving component can drive the first mounting plate 7 to move closer to the feed end of the transport channel 21, so that the end of the sealing strip can enter the transport channel 21 after passing through the guide hole 811. Before the profile 10 moves into the transport channel 21, the operator needs to adjust the position of the mounting base 1 on the operating platform so that the long side of the guide bar 812 is parallel to the transport direction of the profile 10. Then, the height of the guide block 81 in the vertical direction is adjusted so that the guide bar 812 can be inserted into the sealing strip opening 101 of the profile 10 when the profile 10 moves. In this way, the transport direction of the profile 10 is consistent with the direction of the transport channel 21, thereby improving the working stability of the device when guiding the sealing strip into the sealing strip opening 101 of the profile 10.

[0032] Furthermore, a second mounting plate 9 is slidably disposed on the second platform 4 in a direction parallel to the axis of the lifting roller, a first pressing roller 61 is rotatably disposed on the second mounting plate 9, and a fourth driving member for driving the second mounting plate 9 to move is installed on the second platform 4.

[0033] In this embodiment, the second mounting plate 9 can be driven to move horizontally by the fourth driving member so that when the profile 10 moves into the transport channel 21, the first pressing roller 61 can be located directly above the rubber strip opening 101 of the profile 10.

[0034] Furthermore, the mounting base 1 includes two parallel horizontal shafts 11, and the two ends of the two horizontal shafts 11 are connected to the base beams 12 by an interference fit. The mounting bracket 2 is slidably mounted on the horizontal shafts 11 along the axial direction of the horizontal shafts 11, and the mounting bracket 2 is equipped with a second limiting member for limiting its own movement relative to the horizontal shafts 11.

[0035] In this embodiment, the base beam 12 has pre-drilled holes for bolts, allowing it to be fixed to the operating platform. After the operator fixes the base beams 12 at both ends to the operating platform, the mounting bracket 2 can be slid to align the guide strip 812 on the guide block 81 vertically with the adhesive strip opening 101 on the profile 10. The height of the guide block 81 in the vertical direction can then be adjusted using the first limiting member to ensure that the guide strip 812 can pass through the adhesive strip opening 101 during the movement of the profile 10.

[0036] Specifically, the first driving component includes a first screw 22, a first through hole at the bottom of the mounting bracket 2, and a first threaded hole at the bottom of the first platform 3 that matches the first screw 22. The first screw 22 passes through the first through hole and is threaded into the first threaded hole. The second driving component includes a second screw 23, a second through hole at the top of the mounting bracket 2, and a second threaded hole at the top of the second platform 4 that matches the size of the second screw 23. The second screw 23 passes through the second through hole and is threaded into the second threaded hole. The third driving component includes a third screw 41, a third through hole at the first mounting plate 7 along the transport direction of the profile 10, and a third threaded hole at the side of the second platform 4 near the first mounting plate 7 that matches the size of the third screw 41. The third screw 41 passes through the third through hole and is threaded into the third threaded hole. The fourth driving component includes a fourth screw 42. A fourth through hole is provided on the second platform 4 in a direction parallel to the axis of the first pressure roller 61. A fourth threaded hole adapted to the fourth screw 42 is provided on the second mounting plate 9. The fourth screw 42 passes through the fourth through hole and is threaded into the fourth threaded hole.

[0037] Specifically, the first limiting component includes a limiting bolt 71. A vertical strip hole 813 is provided through the guide block 81 on the side away from the first mounting plate 7. A fifth threaded hole adapted to the limiting bolt 71 is provided on the first mounting plate 7. The limiting bolt 71 passes through the strip hole 813 and is threaded into the fifth threaded hole. The second limiting component includes a fifth screw 241 and a pressure plate 242. The pressure plate 242 is located at the bottom of the mounting frame 2. Both the mounting frame 2 and the pressure plate 242 have grooves for the horizontal shaft 11 to pass through. The inner wall of the groove slides in contact with the outer wall of the horizontal shaft 11, and a gap is left between the mounting frame 2 and the pressure plate 242. One end of the pressure plate 242 is bolted to the mounting frame 2, and the other end of the pressure plate 242 has a fifth through hole for the fifth screw 241 to pass through. A sixth threaded hole with a size adapted to the fifth screw 241 is provided on the mounting frame 2. The fifth screw 241 passes through the fifth through hole and is threaded into the sixth threaded hole.

[0038] The sealing strip needs to be wound onto a drum, the length of which is much greater than the length of the profile 10, and the drum is mounted on the operating table by means of non-powered rotation. The movable end of the sealing strip needs to be moved between the profile 10 and the first pressure roller 61. As the profile 10 moves, the profile 10 and the first pressure roller 61 squeeze and pull the sealing strip, which can force the drum to rotate and release the material, so that the sealing strip can be pressed into the strip opening 101 by the first pressure roller 61 while moving with the profile 10.

[0039] However, since the sealing strip is a flexible material, it will stretch and deform under stress between the roll and the first pressure roller 61, and be pressed into the strip opening 101 of the profile 10 while still stretched and deformed. After a profile 10 has completely passed through the transport channel 21, the profile 10 and the first pressure roller 61 release the sealing strip, causing the movable end of the sealing strip to retract, i.e., the end initially pressed into the strip opening 101, thus causing the end of the sealing strip to no longer be flush with the end of the strip opening 101 of the profile 10.

[0040] Therefore, to solve this problem, a second pressure roller 62 is rotatably mounted on the second mounting plate 9 on the side of the first pressure roller 61 away from the guide block 81. Gears 63 are coaxially mounted on the shafts of both the first and second pressure rollers 61. A belt 64 meshes with each gear 63. The diameter of the gear 63 on the first pressure roller 61 is smaller than the diameter of the gear 63 on the second pressure roller 62, so that the linear velocity of the first pressure roller 61 is greater than that of the second pressure roller 62.

[0041] In this embodiment, since the diameter of the gear 63 on the first pressure roller 61 is smaller than the diameter of the gear 63 on the second pressure roller 62, and the linear velocities of the two gears 63 are the same, it can be concluded that the angular velocity of the first pressure roller 61 is greater than the angular velocity of the second pressure roller 62. Therefore, it can be concluded that the linear velocity of the first pressure roller 61 is greater than the linear velocity of the second pressure roller 62. Since the first pressure roller 61 and the second pressure roller 62 act on the same sealing strip, and the linear velocity of the second pressure roller 62 is slower than that of the first pressure roller 61, the segment of the sealing strip passing through the second pressure roller 62 per unit time is shorter than the segment passing through the first pressure roller 61. This causes the sealing strip to be compressed in length when passing between the first pressure roller 61 and the second pressure roller 62, to offset part of the length stretched due to the friction of the profile 10. In this way, the final retraction of the sealing strip can be reduced, improving the installation effect of the sealing strip.

[0042] In order to increase the friction between the sealing strip and the first pressing roller 61 and the second pressing roller 62, anti-slip textures are provided on the outer walls of the first pressing roller 61 and the second pressing roller 62 to prevent the first pressing roller 61 and the second pressing roller 62 from slipping on the surface of the sealing strip.

[0043] The implementation principle of the PVC profile sealing strip roller introduction device in this embodiment is as follows: When the profile 10 moves to the feeding end of the transport channel 21, the operator needs to manually move one end of the sealing strip to the feeding end of the transport channel 21 along the transport direction of the profile 10, and position the sealing strip directly above the sealing strip opening 101 of the profile 10. The material support mechanism 5 can support the bottom of the profile 10, and the pressing mechanism 6 can press down to abut against the sealing strip. Under the pressure of the pressing mechanism 6, the sealing strip will be embedded into the sealing strip opening 101 of the profile 10 and abut against the profile 10. Since the profile 10 is driven to move by the extruder, friction is generated between the sealing strip and the profile 10, so that it can move together with the profile 10 while being pressed down to embed into the sealing strip opening 101 of the profile 10. After the profile 10 has completely passed through the transport channel 21, the sealing strip can be cut along the end of the profile 10. Compared to traditional installation methods, the PVC profile sealing strip roller pressing and guiding device of this application eliminates the need for workers to manually press the sealing strip into the strip opening 101, thereby reducing the labor intensity of workers and improving production efficiency.
