Description

Technical Field

[0001] This invention relates to the field of aluminum alloy profile processing technology, and in particular to an integrated device for threading and positioning heat-insulating aluminum alloy profiles. Background Technology

[0002] Thermal insulation aluminum alloy profiles achieve thermal break insulation by inserting thermal insulation strips into the profile cavity, and are the core components of building energy-saving doors and windows. At present, the process of inserting thermal insulation strips in the industry generally relies on manual operation. Operators need to manually position the aluminum alloy profiles first, and then insert the thermal insulation strips one by one into the thermal insulation cavity of the profiles. This process has the following significant defects: (1) Low efficiency: The accuracy of manual positioning depends on the operator's experience. The strip insertion process requires continuous adjustment of force and angle, and the insertion time for a single profile is as long as 1-3 minutes; (2) High labor intensity: The thermal insulation strip and the profile cavity are interference fit. Manual insertion requires a large pushing force. Long-term operation can easily lead to wrist and waist strain of the operator, and the stability of operation decreases with the consumption of physical strength; (3) Unstable quality: Manual operation is prone to problems such as thermal insulation strip skew, wrinkles or uneven ends, which leads to a decrease in the sealing performance after the profile is assembled.

[0003] A search revealed that the invention patent with authorization announcement number CN103192245B discloses an aluminum alloy thermal break profile, particularly an automatic strip threading machine for an aluminum alloy thermal break profile. Based on the aforementioned patent, it was found that although the existing technology has achieved automatic strip threading for a single profile, it only sets up a single working channel and cannot achieve simultaneous operation of multiple profiles, making it difficult to meet the needs of large-scale production. Therefore, there is an urgent need to propose an integrated strip threading and positioning device for thermal break aluminum alloy profiles to improve the above problems. Summary of the Invention

A plurality of limiting rings are fixedly installed on the outer wall of the feeding rollers, and the heat insulation strip moves along the gap between two adjacent limiting rings. The support platform is fixedly installed at the top end of the feeding frame.

[0019] In summary, by adopting the above structure, the present invention has the following advantages compared with the prior art:

[0020] 1. In this invention, through the cooperation of the lifting frame, fixed seat, inclined groove, sliding roller and clamping frame in the positioning component, the first electric push rod drives the first lifting frame to move the lifting frame up and down along the inner wall of the U-shaped groove. During the upward movement of the lifting frame, the sliding roller is guided by the inclined groove on the fixed seat and undergoes lateral displacement, thereby pulling the clamping frame to slide along the inner wall of the lifting frame and approach the aluminum alloy profile. At the same time, the buffer spring in the clamping frame cooperates with the clamping seat and pulley to form an elastic buffer while clamping the profile. This not only realizes the synchronous automatic positioning and clamping of multiple aluminum alloy profiles, ensuring the uniform position of the profiles at each station, but also avoids scratches, indentations and other damage to the surface of the profile caused by hard clamping.

[0021] 2. In this invention, through the cooperation of the displacement mechanism and the strip-threading assembly, the forward and reverse motor of the displacement mechanism drives the first threaded rod to rotate, causing the first movable seat and the movable table to move smoothly along the slide rail, thereby adjusting the horizontal position of the strip-threading assembly. At the same time, the second electric push rod of the strip-threading assembly drives the L-shaped plate to lift the second lifting frame and the connecting frame. Combined with the one-to-one correspondence design between the connecting frame and the positioning assembly station and the strip feeding groove, multiple heat insulation strips can be accurately pushed into the corresponding profile heat insulation cavity simultaneously, realizing multi-station synchronous strip-threading operation, which greatly improves processing efficiency. Furthermore, through the cooperation of the negative pressure box, piston sleeve, traction rod and suction cup in the adsorption assembly, when the second electric push rod drives the L-shaped plate to move down, the traction rod simultaneously drives the movable plate and piston sleeve to move down in the negative pressure box, so that a negative pressure environment is formed at the top of the negative pressure box. The negative pressure is transmitted to the suction cup at the bottom of the connecting frame through the air extraction pipe, corrugated pipe and air guide pipe. The suction cup adsorbs the heat insulation strip in the strip feeding groove, ensuring that the heat insulation strip is accurately and smoothly inserted into the profile heat insulation cavity, improving the stability of strip-threading quality.

[0022] 3. In this invention, by cooperating with the rack seat, gear, second threaded rod, and cutter in the cutting assembly, the rack seat and gear do not mesh during the strip threading process, which does not affect the strip threading operation. After the strip threading is completed, when the displacement mechanism drives the strip threading assembly to move towards the feeding guide assembly, the rack seat moves synchronously and meshes with the driving gear to rotate. The gear drives the second threaded rod to rotate in the connecting cavity, thereby driving the second movable seat to drive the cutter to slide along the movable groove. Thus, by setting the meshing stroke of the rack seat and gear, the moving distance of the cutter can be precisely controlled, realizing the mechanical linkage between the strip threading action and the cutting action. That is, after the heat insulation strip is inserted into the heat insulation cavity of the profile to a preset length, the synchronous fixed-length cutting of multiple heat insulation strips is automatically completed, simplifying the equipment structure, reducing the control complexity, and improving the degree of processing integration.

[0023] 4. In this invention, the feeding rollers, limiting rings, and feeding grooves of the feeding guide assembly work together to traction and convey the heat insulation strips using multiple sets of feeding rollers of different heights. The limiting rings on the outer wall of the feeding rollers limit each heat insulation strip, preventing multiple heat insulation strips from tangling or shifting during conveying. At the same time, the feeding grooves on the top of the support platform correspond one-to-one with the limiting channels of the feeding rollers, receiving the conveyed heat insulation strips and providing precise guidance. Furthermore, the feeding grooves precisely correspond to the positions of the positioning components and the connecting frames of the threading components, providing orderly feeding assurance for simultaneous threading at multiple positions and ensuring that each heat insulation strip can be accurately conveyed to the corresponding processing position.

[0042] A support frame 1 is provided, and a positioning component 2 is provided on the top of the support frame 1 for positioning aluminum alloy profiles at multiple workstations. The positioning component 2 includes a support frame 21 that is fixedly installed at equal intervals on the top of the support frame 1, and a support plate 22 is fixedly installed on the top of the inner wall of the support frame 21. U-shaped grooves 27 are provided on the support frame 21 at equal intervals. Lifting frames 26 are movably provided on both sides of the inner wall of the U-shaped grooves 27.

The movable platform 35 is slidably connected to the slide rails 33.

[0044] The strip insertion assembly 4 is installed on the moving end of the displacement mechanism 3 and is used to insert the thermal insulation strip into the thermal insulation cavity of the aluminum alloy profile. The strip insertion assembly 4 includes a movable frame 41 fixedly installed on one side of the top of the movable platform 35, and a second electric push rod 42 is fixedly installed on the top of the movable frame 41. An L-shaped plate 45 is fixedly installed at the output end of the second electric push rod 42. A second opening is provided at the bottom of the movable frame 41 for the bottom end of the L-shaped plate 45 to pass through. The bottom end of the L-shaped plate 45 extends to the outside of the movable frame 41 and is fixedly installed with a second lifting frame 46. The bottom of the second lifting frame 46 is fixedly installed with connecting frames 43 distributed at equal intervals. The positions of the connecting frames 43 correspond one-to-one with the positions of the strip feeding grooves 7. An adsorption assembly is provided between the 3 and the movable frame 41. The adsorption assembly includes a negative pressure box 44 fixedly installed on the inner wall of the top of the movable frame 41. The negative pressure box 44 has first movable holes 417 on both sides of its bottom. A traction rod 413 passing through the first movable hole 417 is fixed to one end of the top of the L-shaped plate 45. A movable plate 415 is fixedly installed on the top of the traction rod 413. A piston sleeve 416 that fits against the inner wall of the negative pressure box 44 is fixedly installed on the outer wall of the movable plate 415.

A second air guide pipe 410 is fixedly installed at the bottom of the switch valve 411, and a connecting pipe 49 is fixedly installed at the bottom of the second air guide pipe 410. A first air guide pipe 48 is fixedly inserted through the top of the connecting frame 43 into the second lifting frame 46, and the top of the first air guide pipe 48 is fixedly connected to the connecting pipe 49.

The second electric push rod 42 drives the L-shaped plate 45 to move the second lifting frame 46 and the connecting frame 43 down to the strip feeding groove 7. During this process, the traction rod 413 at the top of the L-shaped plate 45 drives the movable plate 415 and the piston sleeve 416 to move down in the negative pressure box 44, so that a negative pressure is formed at the top of the negative pressure box 44. When the suction cup 47 is in full contact with the heat insulation strip, the switch valve 411 is opened. The negative pressure is transmitted to the suction cup 47 at the bottom of the connecting frame 43 through the air extraction pipe 414, the corrugated pipe 412, the second air guide pipe 410, the connecting pipe 49 and the first air guide pipe 48. The suction cup 47 adsorbs the heat insulation strip in the strip feeding groove 7, thereby simultaneously completing the precise pushing of multiple heat insulation strips into the corresponding profile heat insulation cavity, realizing multi-station synchronous strip threading operation.

[0045] The feeding guide assembly 5 is installed on the top of one end of the support frame 1 and is used to guide and convey the heat insulation strip.

[0046] A support platform 6 is fixedly installed at the top end of the feeding guide component 5 near the positioning component 2, and the top of the support platform 6 is provided with equally spaced feeding grooves 7. The positions of the feeding grooves 7 correspond one-to-one with the work positions of the positioning component 2. A cutting component 8 is provided inside the support platform 6 for cutting the heat insulation strip.

[0047] In this invention, the cutting component 8 includes a connecting cavity 83 formed within a support platform 6, and a second threaded rod 84 is rotatably connected to the inner wall of the connecting cavity 83. One end of the second threaded rod 84 extends into the top frame 31 and is fixedly mounted with a gear 82. Movable grooves 87 are formed on the top of the connecting cavity 83 and one side of the feeding groove 7, and L-shaped cutters 86 are movably arranged on the inner wall of each movable groove 87. Second movable seats 85, evenly distributed, are screwed onto the second threaded rod 84, and the second movable seats 85 are fixedly connected to the cutters 86. A rack seat 81 is fixedly installed on one side of the first movable seat 37, and the rack seat 81 meshes with the gear 82. After the strip is threaded, when the displacement mechanism 3 drives the strip threading assembly 4 to move towards the feeding guide assembly 5, the rack seat 81 moves synchronously and meshes with the drive gear 82 to rotate, which drives the second threaded rod 84 to rotate in the connecting cavity 83, thereby driving the second movable seat 85 to drive the cutter 86 to slide along the movable groove 87, thus realizing the mechanical linkage between the strip threading action and the cutting action, and automatically completing the synchronous fixed-length cutting of multiple heat insulation strips.

[0048] In this invention, the feeding guide assembly 5 includes a feeding frame 51 fixedly installed at the top of one end of the support frame 1, and multiple feeding rollers 52 of different heights are rotatably connected to the feeding frame 51. Multiple limiting rings 53 are fixedly installed on the outer wall of the feeding rollers 52. The heat insulation strip moves along the gap between two adjacent limiting rings 53. The support platform 6 is fixedly installed at the top end of the feeding frame 51. The feeding rollers 52 of the feeding guide assembly 5 form a traction conveyor for the heat insulation strip, while the limiting rings 53 limit each heat insulation strip to prevent multiple heat insulation strips from tangling or shifting during the conveying process.

[0049] In summary, the working principle of this invention is as follows: First, the heat insulation strip is conveyed in an orderly manner through the feeding guide component 5. Multiple feeding rollers 52 of different heights are rotatably connected on the feeding frame 51 of the feeding guide component 5 to pull the heat insulation strip. The limiting ring 53 on the outer wall of the feeding roller 52 limits each heat insulation strip individually to prevent entanglement and deviation. After being conveyed, the heat insulation strip enters the strip feeding groove 7 on the top of the support platform 6. The strip feeding groove 7 corresponds precisely to the limiting channel of the feeding roller 52 to realize the reception and guidance of the heat insulation strip.

[0050] Next, the aluminum alloy profile is placed in the area of ​​the support plate 22 on the positioning component 2. The positioning component 2 is activated to perform multi-station synchronous positioning of the aluminum alloy profile. The first electric push rod 24 on the inner wall of the support frame 1 drives the first lifting frame 23 to rise. The lifting plate 25 on the top of the first lifting frame 23 drives the lifting frame 26 to move upward along the inner wall of the U-shaped groove 27 of the support frame 21. During the upward movement of the lifting frame 26, the sliding roller 213 at the bottom end of the bottom connecting plate 211 of the clamping frame 210 slides along the inclined groove 214 and undergoes lateral displacement, thereby pulling the clamping frame 210 to slide along the inner wall of the lifting frame 26 and approach the aluminum alloy profile. The buffer spring 215 in the clamping frame 210 cooperates with the clamping seat 216 to form an elastic clamping of the profile. The pulley 217 on the clamping seat 216 avoids scratching the surface of the profile during the clamping process, and finally achieves synchronous positioning and fixing of multiple aluminum alloy profiles.

[0051] After positioning, the strip threading assembly 4 and the displacement mechanism 3 cooperate to start the strip threading operation. The second electric push rod 42 of the strip threading assembly 4 drives the L-shaped plate 45 to move down. The bottom end of the L-shaped plate 45 drives the second lifting frame 46 and the bottom connecting frame 43 to descend synchronously to the strip feeding groove 7. During this process, the traction rod 413 at the top of the L-shaped plate 45 drives the movable plate 415 and the piston sleeve 416 to move down in the negative pressure box 44, so that a negative pressure is formed at the top of the negative pressure box 44. When the suction cup 47 is in full contact with the heat insulation strip, the strip is opened. When the valve 411 is turned on, the negative pressure is transmitted through the suction pipe 414, the bellows pipe 412, the second air guide pipe 410, the connecting pipe 49 and the first air guide pipe 48 to the suction cup 47 at the bottom of the connecting frame 43. The suction cup 47 adsorbs the heat insulation strip in the strip delivery groove 7. Then, the forward and reverse motor 32 of the displacement mechanism 3 drives the first threaded rod 36 in the top frame 31 to rotate, which drives the first movable seat 37 and the top movable platform 35 to move smoothly along the slide rail 33, and drives the heat insulation strip to accurately penetrate the heat insulation cavity of the aluminum alloy profile.

[0052] After the strip is threaded to the preset length, the displacement mechanism 3 drives the threading assembly 4 to reset and move towards the feeding guide assembly 5. At this time, the second electric push rod 42 drives the L-shaped plate 45 to move upward, and the traction rod 413 drives the movable plate 415 and the piston sleeve 416 to move upward and reset. The negative pressure in the negative pressure box 44 disappears, the suction cup 47 releases the heat insulation strip, and the rack seat 81 on one side of the first movable seat 37 moves synchronously and meshes with the drive gear 82 to rotate. The gear 82 drives the second threaded rod 84 in the connecting cavity 83 to rotate. The second movable seat 85 on the second threaded rod 84 drives the cutter 86 to slide along the movable groove 87 to synchronously cut the heat insulation strip after it has been threaded into the profile, thus completing one multi-station threading operation. The above process can be repeated to achieve continuous processing.

[0053] In light of current practical needs, the above-described embodiments of this invention are not limited to these specific implementations. Any changes made within the scope of knowledge possessed by those skilled in the art, without departing from the concept of this invention, still fall within the protection scope of this invention.
