Description

Technical Field

[0001] The utility model relates to the technical field of plastic-steel profiles, and more specifically to an automatic feeding device for plastic-steel profiles. Background Art

[0002] Plastic-steel profiles refer to PVC profiles used in the manufacture of doors and windows. They appeared in Germany as early as the late 1950s, were introduced to my country in 1983, and became widely used in the late 1990s. Because doors and windows made solely from PVC profiles lack strength, steel is often added to the mold cavity to enhance their durability. Therefore, plastic doors and windows made with steel added to the profile are often referred to as plastic-steel doors and windows. With the widespread use of plastic-steel doors and windows, the PVC profiles used to make them are customarily referred to as plastic-steel profiles.

[0003] When temporary cutting is required during processing, a cutting machine is needed. According to the structure of the currently commonly used cutting machine, the plastic-steel profile is generally clamped by a clamping device, and then the cutting knife is pressed down to cut the plastic-steel profile. When in use, the material is generally loaded and unloaded manually, which is not efficient enough. At the same time, only the clamping device of the cutting machine is used for fixing, and there is a problem of single-point force. During cutting, the plastic-steel profile may move, resulting in an uneven cutting surface. Utility Model Content

[0023] The first embodiment of the present utility model is as follows:

[0024] An automatic feeding device for plastic-steel profiles includes a bottom plate 9 and a base 1, and a lifting component 8 for controlling the lifting of the base 1 is provided between the bottom plate 9 and the base 1; a loading component and a clamping component are provided on the upper part of the base 1, and the clamping component is located above the loading component. When loading, the plastic-steel profile is placed on the loading component, and then the plastic-steel profile can be moved along the extension direction of the loading component, which is more convenient to control the length to be cut and more convenient to make fine adjustments. After adjusting the position of the plastic-steel profile, the plastic-steel profile is clamped using the clamping device, and used together with the clamping device of the cutting machine, the clamping is more stable.

[0025] During use, since the structures of cutting machines of different models or brands are slightly different, their heights are not exactly the same. Therefore, in order to ensure the applicability of this device, a lifting component 8 is set. There are two groups of lifting components 8. The two groups of lifting components 8 are respectively located at the front and rear ends of the base 1. At the same time, a spirit level is set on the upper part of the base 1, which can adjust the height to ensure the level of the base 1.

[0026] The lifting assembly 8 includes a lifting seat 81 fixedly mounted on the upper part of the base plate 9. A worm gear 82 is provided on the upper part of the lifting seat 81 in a relatively rotatable manner. A wire hole is provided in the middle of the worm gear 82. A screw rod 83 is connected to the inside of the wire hole in an engaging manner. The lower part of the screw rod 83 is located inside the lifting seat 81. A worm 84 is provided horizontally through the inside of the base 1. The worm 84 is connected to the worm gear 82 in an engaging manner. One end of the worm 84 passes through the side of the base 1 and is fixedly connected to a handle.

[0027] By shaking the handle, the worm 84 can be driven to rotate, thereby causing the worm wheel 82 meshing with it to rotate synchronously. During the rotation of the worm wheel 82, the lead screw 83 inside it will also be driven to move up and down, thereby realizing lifting and lowering control.

[0028] Among them, the worm gear 82 and the lifting seat 81 can be connected through a bearing, the lifting seat 81 is connected to the outer ring of the bearing, and the worm gear 82 is connected to the inner ring of the bearing. At the same time, the diameter of the wire hole is also set to be smaller than the diameter of the hole in the middle of the bearing to ensure that the screw rod 83 can pass through the middle of it.

[0029] A protective plate 11 for protecting the lifting assembly 8 is provided on the side of the base 1. A gap is left between the lower end of the protective plate 11 and the bottom plate 9. The gap is the same as the lifting range of the lifting assembly 8, ensuring that the protective plate 11 will not affect the operation of the lifting assembly 8 while protecting the lifting assembly 8.

[0030] The loading assembly includes several rollers 3 rotatably connected to the base 1. The several rollers 3 are all located on the same horizontal plane and are parallel to each other. The clamping assembly includes a fixed plate 2 fixedly mounted on the upper part of the base 1. A mounting seat 5 is also provided on the upper part of the base 1. A cylinder 4 is fixedly provided on the mounting seat 5. The cylinder 4 is provided with a piston rod 6. The piston rod 6 passes through the mounting plate and extends to the other side thereof. The end of the piston rod 6 is connected to a movable plate 7, and the movable plate 7 is arranged corresponding to the fixed plate 2.

[0031] At the same time, a notch is provided at the lower part of the fixing plate 2 near the roller 3 , and one end of the roller 3 is located in the notch, ensuring that when the plastic-steel profile is clamped onto the fixing plate 2 , the plastic-steel profile will not detach from the roller 3 .

[0032] When in use, the plastic-steel profile is placed on the roller 3 and then pushed by hand.

[0033] The movable plate 7 is pushed by the cylinder 4 to move toward the fixed plate 2, clamping the plastic-steel profile therein to achieve a stable clamping and fixing.

[0034] There are no less than two groups of clamping components to ensure that there are no less than two clamping force points, so that even if there is a problem with the clamping device on the cutting machine, stable clamping can be achieved, and the device is also suitable for other cutting devices or handheld cutting devices.

[0035] It should be noted that the terms "first, second and third" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.
