DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides an embodiment: a building insulation board cutting machine, comprising:

[0025] A workbench 1, a protective cover 2 is fixedly connected to the upper surface of the workbench 1, and a positioning plate 3 is fixedly connected to one side of the protective cover 2;

[0026] A support shaft 5 is fixedly connected to the inner wall of the workbench 1, and an external sliding sleeve of the support shaft 5 is provided with a push plate 6. The upper surface of the push plate 6 is rotatably connected to a saw blade 7 through a bearing seat, and a push handle 61 is fixedly connected to one side of the push plate 6. The outer wall of the push handle 61 is fixedly connected to a support frame 62. A protective plate 63 is fixedly connected to the top of the support frame 62. The other end of the protective plate 63 is fixedly connected to a movable cover 64, and the movable cover 64 covers the top of the saw blade 7. Through the mutual cooperation of the protective plate 63 and the movable cover 64, the standing end of the staff can be covered, thereby preventing the dust generated during the cutting of the saw blade 7 from affecting the staff, and one end of the central axis of the saw blade 7 is connected to a driving motor for rotating the saw blade 7.

[0027] Furthermore, a positioning assembly 4 is fixedly connected to the upper surface of the workbench 1. A guide groove is opened in the center of the upper surface of the workbench 1, and the width of the guide groove is greater than the thickness of the saw blade 7. The saw blade 7 is located in the center position of the guide groove to facilitate the displacement of the saw blade 7.

[0028] Furthermore, the center of the protective cover 2 is a hollow structure, and the protective cover 2 covers the top of the guide groove of the workbench 1 , and the height of the protective cover 2 is greater than the height of the saw blade 7 protruding from the upper surface of the workbench 1 .

[0029] Furthermore, the positioning assembly 4 includes a bracket 41, which is fixedly connected to the upper surface of the workbench 1. The internal thread of the bracket 41 is connected to a threaded rod 42, one end of the threaded rod 42 is rotatably connected to an adjustment plate 44, and the outer wall of the adjustment plate 44 is fixedly connected to a guide shaft 45. A guide hole adapted for the guide shaft 45 is opened on the bracket 41, and the guide hole is slidably connected to the guide shaft 45. There are two guide shafts 45 in total, and the two guide shafts 45 are symmetrically distributed on both sides of the threaded rod 42. The end of the threaded rod 42 away from the adjustment plate 44 is a spherical structure, and the center of the spherical structure is slidably penetrated by a driving rod 43, and the two ends of the driving rod 43 are also spherical structures.
