Description

Technical Field

[0002] Aluminum alloy, as a lightweight, high-strength, and corrosion-resistant metal material, is widely used in the construction industry, particularly in the manufacture of doors and windows, where it occupies a dominant position and has become the preferred material for door and window manufacturing. However, a disadvantage of aluminum alloy profiles is their poor thermal insulation performance. Therefore, for the purpose of heat preservation, thermal insulation aluminum alloy profiles have come into being. Thermal insulation aluminum alloy profiles, also known as thermal insulation profiles, work by using thermal insulation strips to separate and tightly connect two layers of aluminum alloy into a single unit, forming a new type of thermal insulation aluminum profile. Doors and windows made with this profile completely solve the fatal problem of aluminum alloy's rapid heat conduction and failure to meet energy-saving requirements.

[0003] The strip threading machine is a special equipment for producing thermal insulation aluminum alloy profiles. Its main function is to accurately and quickly thread the thermal insulation strips into the corresponding slots of two aluminum profiles.

[0029] like Figure 1-8As shown, a strip threading machine for producing heat-insulating aluminum profiles includes a strip threading mechanism 1 and a shearing mechanism 2. The shearing mechanism 2 includes a base 201. A crossbeam 202 is fixedly provided above the upper surface of the base 201. One end of the crossbeam 202 is fixedly connected to the base 201. The other end of the crossbeam 202 is fixedly connected to a support 2011. The support 2011 is fixedly connected to the base 201. The crossbeam 202 is hinged with a first connecting rod 203 in a vertical plane. The hinge point is the middle of the first connecting rod 203. The upper end of the first connecting rod 203 is connected to the second connecting rod 204 through a hinge shaft. The hinge shaft is connected to a first spring 206. The other end of the first spring 206 is connected to the crossbeam 202. The other end of the second connecting rod 204 is hingedly connected to a guide rod 205. The guide rod 205 is slidably connected to the base 201. After one end of the aluminum profile 108 contacts the lower end of the first connecting rod 203, as shown Figure 2 As shown, the first connecting rod 203 rotates counterclockwise and causes the guide rod 205 to slide in a direction opposite to the moving direction of the aluminum profile 108.

After the vacuum pump 107 is started, the upper surface of the heat insulation strip 109 fits tightly with the upper surface of the slide groove of the strip-threading block 106.

[0038] When using this embodiment, one end of the thermal insulation strip 109 is inserted into the slot of the strip-threading block 106. After the vacuum pump 107 is activated, the thermal insulation strip 109 is aligned with the upper surface of the slot. The aluminum profile 108 is placed on the roller 102 on the other side. After the equipment is activated, the aluminum profile 108 moves forward driven by the roller 102. When the aluminum profile 108 contacts the toothed disk 105, the textured teeth on the toothed disk 105 roll out texture on the contact surface between the aluminum profile 108 and the thermal insulation strip 109. Furthermore, the corresponding mounting groove on the aluminum profile 108 is aligned with the thermal insulation strip 109, and the aluminum profile 108 continues to move forward along the thermal insulation strip 109 until the thermal insulation strip 109 completely penetrates the mounting groove of the aluminum profile 108.

[0039] After the aluminum profile 108 is threaded and contacts the lower end of the first connecting rod 203, Figure 2 As shown, the first connecting rod 203 rotates counterclockwise about its hinge point with the crossbeam 202, and the guide rod 205 moves in the direction opposite to the movement of the aluminum profile 108. When one end of the guide rod 205 reaches a position between the knife holder 208 and the slider 211, the downward movement of the slider 211 pushes the knife holder 208 downward, thereby cutting off the excess insulation strip 109. At this time, the cylinder 219 contracts and causes the flap 218 to tilt, allowing the aluminum profile 108 located above it to slide down and be collected and stored by staff.
