Description

Technical Field

[0001] This utility model relates to the field of door and window manufacturing technology, and more specifically, to a strip-threading machine for inserting glass strips into aluminum alloy doors and windows. Background Technology

[0002] The strip insertion machine is specifically used to embed thermal break strips into the grooves of aluminum alloy profiles to form a thermal break structure, blocking the conduction of heat between indoors and outdoors, and improving the thermal insulation and sound insulation performance of doors and windows. For example, the automatic strip insertion machine for door and window profile sealing strips proposed in application number "CN202221259780.8" includes a workbench, a support plate fixedly connected to the top of the workbench, a slot opened on the front of the support plate, a threaded column movably connected to the inner side wall of the slot, a handle fixedly connected to one side of the threaded column, a first sliding rod fixedly connected to the inner side wall of the slot, a first hydraulic cylinder fixedly connected to the bottom of the connecting plate, and a pressing wheel fixedly connected to the output shaft of the motor through a coupling.

[0003] However, the above technical solutions do not have an independent tooth-opening mechanism, making it impossible to pre-treat the profile groove. The interlocking force between the thermal break strip and the profile is insufficient, which may lead to the risk of detachment and reduce the thermal and sound insulation performance of the doors and windows. At the same time, the simple limiting is only achieved by the support plate and the sliding rod, which makes the profile prone to displacement during transportation, resulting in deviation of the thermal break strip embedding position and affecting the stability of the thermal break structure. Therefore, we propose a strip insertion machine for aluminum alloy doors and windows to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a strip insertion machine for aluminum alloy doors and windows, which solves the problems of insufficient interlocking force between the thermal break strip and the profile due to the lack of an independent toothing mechanism, which may lead to the risk of detachment and reduce the thermal insulation and sound insulation performance of the doors and windows. At the same time, the simple limiting by the support plate and slide bar makes the profile prone to displacement during transportation, resulting in the thermal break strip embedding position deviation and affecting the stability of the thermal break structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A strip-threading machine for aluminum alloy door and window glass includes a worktable. Several support rollers are movably mounted on the upper end of the worktable. A first profile is placed on the upper end of each support roller. A limiting mechanism is installed at one end of the upper surface of the worktable, and the limiting mechanism is in contact with the first profile. A toothed mechanism is installed on the upper surface of the worktable near the limiting mechanism, and the toothed mechanism is vertically parallel to the first profile. A strip-threading mechanism is installed on the upper surface of the worktable away from the limiting mechanism. A second profile is engaged at the upper end of the strip-threading mechanism, and the second profile overlaps vertically with the first profile. A thermal insulation strip is engaged between the first and second profiles. The gear-opening mechanism includes a first bracket mounted on the upper surface of the workbench. An electric slide rail is mounted on the lower end of the first bracket. A second cylinder is mounted on the upper surface of the first bracket. The output end of the second cylinder movably passes through the interior of the first bracket and is connected to the electric slide rail. Slider blocks are mounted on the front and rear sides of the lower end of the electric slide rail. A second motor is mounted on the lower end of the sliders on the side away from each other. Gears are movably mounted on the lower end of the sliders on the side closer to each other. The output ends of the second motors movably pass through the interior of the sliders and are connected to the gears. The gears are parallel vertically to the first profile and the second profile.

[0007] Preferably, a number of support blocks are installed opposite each other at the front and rear ends of the upper surface of the worktable, and the support rollers are movably installed between the relatively overlapping support blocks.

[0008] Preferably, the limiting mechanism includes a first cylinder, which is respectively installed on the front and rear sides of one end of the worktable surface. The first cylinders are relatively parallel to each other. A connecting frame is installed on the output end of each of the first cylinders. Conveying rollers are movably installed inside the connecting frame. The ends of the conveying rollers that are close to each other are respectively attached to the first profile and the second profile. A first motor is installed on the upper end of the connecting frame. The output end of the first motor moves through the interior of the connecting frame and is connected to the conveying roller.

[0009] Preferably, the threading mechanism includes a second bracket, which is installed on the upper surface of the workbench and at one end away from the conveying roller. A top plate is movably installed at the lower end of the interior of the second bracket, and the top plate is parallel to the first profile vertically. A third cylinder is installed at the upper end of the second bracket, and the output end of the third cylinder movably passes through the interior of the second bracket and is connected to the top plate.

[0010] Preferably, the lower end of the workbench is provided with a placement groove, and a limiting frame is movably installed inside the placement groove. The end of the limiting frame away from the conveying roller is parallel to the top plate. Extension blocks are respectively installed at the front and rear ends of the side of the top plate and the limiting frame that are close to each other. The second profile is installed between the top plate and the limiting frame, and the front and rear ends of the lower surface of the second profile are respectively in contact with the extension blocks.

[0011] Preferably, the top plate has locking grooves at both the front and rear ends near the second profile, and one end of the heat insulation strip is respectively locked and installed inside the locking groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) The present invention is provided with an independent tooth opening mechanism. The height of the tooth opening is adjusted by the electric slide rail driven by the second cylinder to match the slot position of different profiles. Then, the second motor drives the tooth opening to rotate, pre-processing the slots of the first and second profiles to form a toothed structure. Compared with the traditional untoothed profiles, the contact area between the toothed slot and the heat insulation strip is significantly increased, and the biting force is greatly improved, making it difficult for the heat insulation strip to fall off after being embedded, thereby effectively improving the heat insulation and sound insulation performance of doors and windows.

[0014] (2) In this utility model, the top plate and the limiting frame of the strip insertion mechanism use the extension block to laterally limit the second profile, and the locking groove positions and guides the heat insulation strip. The double limiting ensures that the heat insulation strip is accurately embedded, ensuring the stability of the thermal break structure and avoiding performance degradation caused by position deviation.

Detailed Implementation

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 8As shown in the figure, this utility model embodiment proposes a strip-threading machine for aluminum alloy door and window glass, including a worktable 1. Several support rollers 2 are movably mounted on the upper end of the worktable 1. A first profile 4 is placed on the upper end of the support rollers 2. A limiting mechanism 5 is installed at one end of the upper surface of the worktable 1, and the limiting mechanism 5 is in contact with the first profile 4. A toothed mechanism 6 is installed on the upper surface of the worktable 1 near the limiting mechanism 5, and the toothed mechanism 6 is vertically parallel to the first profile 4. A strip-threading mechanism 7 is installed on the upper surface of the worktable 1 away from the limiting mechanism 5. A second profile 8 is engaged at the upper end of the strip-threading mechanism 7, and the second profile 8 overlaps vertically with the first profile 4. A heat insulation strip 9 is engaged between the first profile 4 and the second profile 8. The toothed mechanism 6 includes a first... A bracket 601 is mounted on the upper surface of the workbench 1. An electric slide rail 603 is mounted on the lower end of the interior of the first bracket 601. A second cylinder 602 is mounted on the upper surface of the first bracket 601. The output end of the second cylinder 602 moves through the interior of the first bracket 601 and is connected to the electric slide rail 603. Sliders 604 are mounted on the front and rear sides of the lower end of the electric slide rail 603. A second motor 605 is mounted on the lower end of the side of the sliders 604 that are far apart from each other. A gear 606 is movably mounted on the lower end of the side of the sliders 604 that are close to each other. The output end of the second motor 605 moves through the interior of the sliders 604 and is connected to the gear 606. The gear 606 is parallel vertically to the first profile 4 and the second profile 8.

[0026] like Figures 4 to 8As shown, in another embodiment of this utility model, several support blocks 3 are installed opposite each other at the front and rear ends of the upper surface of the workbench 1. Support rollers 2 are movably installed between the relatively overlapping support blocks 3. The limiting mechanism 5 includes a first cylinder 501, which is installed on the front and rear sides of one end of the upper surface of the workbench 1. The first cylinders 501 are relatively parallel to each other. A connecting frame 502 is installed on the output end of the first cylinder 501. A conveying roller 503 is movably installed inside the connecting frame 502. The ends of the conveying rollers 503 that are close to each other are respectively attached to the first profile 4 and the second profile 8. A first motor 504 is installed on the upper end of the connecting frame 502. The output end of the first motor 504 movably passes through the interior of the connecting frame 502 and is connected to the conveying roller 503. The strip threading mechanism 7 includes a second bracket 701, which is installed on the upper surface of the workbench 1 and at the end away from the conveying roller 503. A top plate 703 is movably installed at the lower end of the second support 701. The top plate 703 is parallel to the first profile 4 vertically. A third cylinder 702 is installed at the upper end of the second support 701. The output end of the third cylinder 702 movably passes through the interior of the second support 701 and is connected to the top plate 703. A placement groove 706 is provided at the lower end of the workbench 1. A limit frame 705 is movably installed inside the placement groove 706. The end of the limit frame 705 away from the conveyor roller 503 is parallel to the top plate 703. Extension blocks 708 are respectively installed at the front and rear ends of the side of the top plate 703 and the limit frame 705 that are close to each other. The second profile 8 is installed between the top plate 703 and the limit frame 705, and the front and rear ends of the lower surface of the second profile 8 are respectively attached to the extension blocks 708. The front and rear ends of the side of the top plate 703 that are close to the second profile 8 are respectively provided with locking grooves 704. One end of the heat insulation strip 9 is respectively locked and installed inside the locking groove 704.

[0027] The user first inserts one end of the thermal insulation strip 9 into the locking groove 704 of the top plate 703, and then manually straightens the thermal insulation strip 9. The locking groove 704 provides initial positioning for the thermal insulation strip 9, ensuring that its embedding direction is aligned with the profile groove and avoiding displacement.

[0028] Then, the second profile 8 is placed between the support roller 2 at the upper end of the workbench 1 and the conveying roller 503 of the limiting mechanism 5. The first motor 504 is started to drive the conveying roller 503 to rotate, which drives the second profile 8 to move towards the toothed mechanism 6. The support roller 2 reduces the friction between the profile and the workbench 1 and reduces surface wear. The conveying roller 503 adheres to the profile through the pressure of the first cylinder 501 to ensure that there is no slippage or deviation during the conveying process.

[0029] The toothed mechanism 6 drives the electric slide rail 603 to move up and down through the second cylinder 602, adjusting the height of the toothed gear 606 to match the slot position of the second profile 8. Then, the second motor 605 drives the toothed gear 606 to rotate, processing a toothed structure on the surface of the profile slot. The toothed structure increases the contact area between the profile slot and the thermal break strip 9, thereby improving the overall interlocking force, preventing the thermal break strip 9 from falling off, and enhancing the thermal insulation and sound insulation performance of doors and windows.

[0030] After the teeth are opened, the second profile 8 continues to move toward the strip insertion mechanism 7. At this time, the heat insulation strip 9 is gradually inserted into the groove of the second profile 8 through the guide of the locking groove 704, completing the initial strip insertion. The locking groove 704 provides linear guidance for the heat insulation strip 9, ensuring that the insertion path is completely matched with the groove, avoiding skewness or jamming.

[0031] Then the user takes out the second profile 8 and the heat insulation strip 9 that have been threaded, flips the second profile 8 so that the heat insulation strip 9 is at the bottom, and then supports the lower surface of the second profile 8 by the extension block 708 of the threading mechanism 7, while inserting the other end of the heat insulation strip 9 back into the locking groove 704.

[0032] Then, the first profile 4 is placed between the support roller 2 and the conveying roller 503, and the above tooth-opening process is repeated. Subsequently, the first profile 4 moves towards the strip-threading mechanism 7 and overlaps with the second profile 8 that has already been threaded. At the same time, the heat insulation strip 9 is embedded into the toothed groove of the first profile 4 to complete the threading of the first profile 4, the heat insulation strip 9 and the second profile 8, forming a broken bridge structure of the first profile 4-heat insulation strip 9-second profile 8.

[0033] The working principle of a strip insertion machine for aluminum alloy doors and windows:

[0034] In use, the user first inserts one end of the heat insulation strip 9 into the engaging groove 704 of the top plate 703, and then manually straightens the heat insulation strip 9. The engaging groove 704 provides initial positioning for the heat insulation strip 9, ensuring that its embedding direction is aligned with the profile groove to avoid misalignment. Then, the second profile 8 is placed between the support roller 2 at the upper end of the worktable 1 and the conveying roller 503 of the limiting mechanism 5. The first motor 504 is started to drive the conveying roller 503 to rotate, causing the second profile 8 to move towards the toothing mechanism 6. The toothing mechanism 6 drives the electric slide rail 603 to move up and down through the second cylinder 602, adjusting the height of the toothing gear 606 to match the groove position of the second profile 8. Subsequently, the second motor 605 drives the toothing gear 606 to rotate, machining a toothed structure on the surface of the profile groove. The second profile 8 continues to move toward the threading mechanism 7. At this time, the heat insulation strip 9 is gradually inserted into the groove of the second profile 8 by the guide of the engaging groove 704, completing the initial threading. Then, the user takes out the threaded second profile 8 and the heat insulation strip 9, flips the second profile 8 so that the heat insulation strip 9 is at the lower end, and then supports the lower surface of the second profile 8 by the extension block 708 of the threading mechanism 7. At the same time, the other end of the heat insulation strip 9 is inserted into the engaging groove 704 again. Then, the first profile 4 is placed between the support roller 2 and the conveying roller 503, and the above tooth opening process is repeated. Subsequently, the first profile 4 moves toward the threading mechanism 7 and overlaps with the threaded second profile 8. The heat insulation strip 9 is simultaneously inserted into the tooth opening groove of the first profile 4 to complete the threading of the first profile 4, the heat insulation strip 9 and the second profile 8.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
