[0002] Currently, most profile forming machine safety doors adopt a single-channel, single-door design, which suffers from operational jamming and insufficient rigidity. Traditional cylinder-driven systems are prone to damage due to guide rail installation misalignment, and the metal impact blocks generate significant noise and have a short buffer distance. There is an urgent need for a protective device that can improve smoothness, reduce maintenance costs, and decrease noise. Utility Model Content

Each door mechanism includes an outer door and an inner door. The outer door has a first slider that cooperates with the first linear guide rail on its top outer side and a second linear guide rail on its top inner side. The inner door has a second slider that cooperates with the second linear guide rail on its top outer side and a top plate at its bottom. The outer door has a top block at its bottom corresponding to the top plate. When the inner door moves, the top plate pushes the top block to achieve linkage between the outer door and the inner door. Deep groove ball bearings are installed at the bottom of both the outer door and the inner door.

[0005] In some embodiments, a guide rod is provided on the upper inner side of the operating port, and a guide block is slidably provided on the guide rod. The guide block is fixedly connected to the inner door. The guide block is connected to the output end of a large-diameter rodless cylinder, and the safety door assembly is driven to open and close through the large-diameter rodless cylinder.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] refer to Figures 1 to 5 This application provides a safety door protection device for a dual-channel profile machine, including a frame 1 and door mechanisms symmetrically arranged on both sides of the operating opening. The operating opening is located on the front side of the frame 1, and a first linear guide rail 2 is fixed to the top of the operating opening. Each door mechanism includes an outer door 3 and an inner door 4. The outer door 3 has a first slider 5 that cooperates with the first linear guide rail 2 on its top outer side, and a second linear guide rail 6 on its top inner side. The inner door 4 has a second slider 7 that cooperates with the second linear guide rail 6 on its top outer side, and a top plate 8 at its bottom. The outer door 3 has a top block 9 at its bottom that corresponds to the top plate 8. When the inner door 4 moves, the top plate 8 pushes the top block 9 to achieve linkage of the outer door 3. Deep groove ball bearings 10 are installed at the bottom of both the outer door 3 and the inner door 4.

[0018] Top blocks 9 are provided on both sides of the bottom of the outer door 3. During the opening and closing of the door mechanism, the top plate 8 of the inner door 4 contacts the top blocks 9, which drives the outer door 3 to move.

[0019] In some embodiments, a guide rod 11 is provided on the upper inner side of the operating port, and a guide block 12 is slidably provided on the guide rod 11. The guide block 12 is fixedly connected to the inner door 4. The guide block 12 is connected to the output end of a large-diameter rodless cylinder, and the safety door assembly is driven to open and close through the large-diameter rodless cylinder.

[0020] In some embodiments, the deep groove ball bearing 10 is a planar bearing.

[0021] In some embodiments, hydraulic buffers are provided on both sides of the guide rod 11 to limit the range of motion of the guide block 12.

[0022] In some embodiments, silicone bumpers are provided on the opposing contact surfaces of the inner doors 4 on both sides.

[0023] The opening and closing action of the door mechanism is performed according to the following procedure:

[0024] Drive start: The large-diameter rodless cylinder pushes the guide block 12 to move linearly along the guide rod 11, which drives the fixed inner door 4 to move synchronously;

[0025] Inner door 4 main stroke:

[0026] The inner door 4 slides along the second linear guide rail 6 via the second slider 7;

[0027] The bottom deep groove ball bearing 10 is floating and guided to eliminate off-center load friction;

[0028] Three-way linkage of outer doors:

[0029] When the inner door 4 moves to the set position, its bottom top plate 8 contacts the top block 9 of the outer door 3;

[0030] The top plate 8 pushes the top block 9, causing the outer door 3 to slide along the first linear guide rail 2 via the first slider 5;

[0031] Buffer deceleration:

[0032] When the guide block 12 approaches the end of its stroke, it impacts the hydraulic buffers at both ends of the guide rod 11, and the kinetic energy is absorbed by the hydraulic damping.

[0033] When the inner doors on both sides are closed, the elastic deformation of the silicone impact block extends the buffer distance, achieving a soft landing.

[0034] This utility model improves material passage efficiency through a dual-channel, four-door structure, and achieves precise linkage between the two doors through the mechanical coupling of the top plate 8 and the top block 9; the floating guide of the deep groove ball bearing 10 completely eliminates over-positioning, and the linear constraint of the guide rod 11 and the guide block 12 reduces friction loss; the silicone impact block extends the buffer distance and reduces impact noise; the hydraulic damper absorbs the kinetic energy at the end of the cylinder and reduces mechanical impact; the modular design shortens the replacement time of vulnerable parts such as bearings and impact blocks.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
