Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a building material cutting device. Background Art

[0002] Currently, building material cutting is mostly done by hand tools or some small electric saws.

[0003] An existing patent (publication number: CN212552079U) discloses a construction material cutting device for use on construction sites. A servo motor is provided to drive a double-threaded screw to rotate, thereby driving a slider to move inward, and then quickly clamping and fixing the material from both sides. The operation is not only simple, but also firmly fixed and more practical. A water-absorbing sponge is provided inside the cutting knife, so that when the cutting knife cuts metal, water is injected into the water-absorbing sponge. When the cutting knife rotates, the water inside the water-absorbing sponge can be thrown out to cool the surface of the cutting knife.

[0004] However, the above technical solution has certain defects. The debris generated when the cutting knife cuts the material will adhere to the outer wall of the double-threaded screw through the slide groove, thereby causing the movement of the slider to be blocked or even unable to move along the outer wall of the double-threaded screw. As a result, the device will affect the clamping of the material in the later stage. For this reason, a building material cutting device is proposed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a building material cutting device to solve the technical problems raised in the above background.

[0011] As a preferred technical solution of a building material cutting device of the utility model, a rubber pad is fixedly connected to the inner side wall of the clamping head, and a protrusion is fixed on the surface of the rubber pad.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] The utility model drives two groups of movable blocks to be relatively close to each other and cooperate with the clamping head through the bidirectional threaded rod, so that the material of the device can be clamped conveniently and quickly, and at the same time, it can prevent the debris generated by the material when the device is used for cutting from adhering to the surface of the bidirectional threaded rod, thereby affecting the practicability of the device.

DETAILED DESCRIPTION

[0020] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0021] The following describes an embodiment of the utility model based on its overall structure.

[0022] A building material cutting device, such as Figure 1-5 As shown, it includes a workbench 100, the top of the workbench 100 is fixedly connected to a cutting mechanism 110, the inside of the workbench 100 is rotatably connected to a bidirectional threaded rod 130, the outer wall of the bidirectional threaded rod 130 is threadedly connected to a movable block 131, both sides of the movable block 131 are fixedly connected to a clamping head 120 extending to the top of the workbench 100, a steel wire rope 140 is fixed to the rear side of the movable block 131, a fixing bar 142 is fixed to the bottom of the steel wire rope 140, and a shielding plate 143 is fixed to the rear side of the fixing bar 142.

[0023] The top and bottom of the movable block 131 are in contact with the inner wall of the first through slot 101 , and the movable block 131 is slidably connected to the first through slot 101 .

[0024] The fixing strip 142 and the shielding plate 143 are an integral structure. A second through slot 102 is formed through the top of the workbench 100 , and the size of the second through slot 102 matches that of the shielding plate 143 .

[0025] The bidirectional threaded rod 130 penetrates through the workbench 100 and extends to the outside thereof, and an end of the bidirectional threaded rod 130 is connected to a motor via a coupling.

[0026] When in use, starting the motor can drive the bidirectional threaded rod 130 to rotate. When the bidirectional threaded rod 130 rotates, it can drive the movable block 131 to slide on its outer wall. When the movable block 131 slides, the clamping head 120 can be relatively close, and the clamping head 120 can be relatively close to clamp the material. When the clamping head 120 is relatively close, the wire rope 140 can be pulled synchronously through the rotation of the rotating wheel 141 for transmission. When the wire rope 140 moves, it can drive the fixed bar 142 to move. The movement of the fixed bar 142 can drive the baffle plate 143 to move. The movement of the baffle plate 143 can make the baffle plate 143 move upward, so that the baffle plate 143 passes through the second through groove 102 and extends to the top of the workbench 100, which can provide protection for the staff. When the clamping head 120 moves to both ends to release the clamping of the material, the baffle plate 143 can slide along the second through groove 102 to the bottom of the workbench 100.

[0027] Please refer to Figure 3 , Figure 5A rotating groove 103 is formed on both sides of the first through groove 101 , and a rotating wheel 141 is rotatably connected inside the rotating groove 103 , and the outer wall of the rotating wheel 141 is in contact with the steel wire rope 140 .

[0028] The rotating wheel 141 can be rotated inside the rotating groove 103 , so that the steel wire rope 140 can be transmitted along the rotating wheel 141 .

[0029] Please refer to Figure 2 The inner side wall of the clamping head 120 is fixedly connected with a rubber pad, and a protrusion is fixed on the surface of the rubber pad.

[0030] This can prevent the material from sliding on the inner wall of the clamping head 120 when the material is clamped, and can play a certain anti-slip role.

[0031] When in use, the starting motor can drive the bidirectional threaded rod 130 to rotate. When the bidirectional threaded rod 130 rotates, it can drive the movable block 131 to slide on its outer wall. When the movable block 131 slides, the clamping head 120 can be relatively close, and the clamping head 120 can be relatively close to clamp the material. When the clamping head 120 is relatively close, the wire rope 140 can be pulled synchronously through the rotation of the rotating wheel 141 for transmission. When the wire rope 140 moves, it can drive the fixed bar 142 to move. The movement of the fixed bar 142 can drive the baffle plate 143 to move. The movement of the baffle plate 143 can make the baffle plate 143 move upward, so that the baffle plate 143 passes through the second through groove 102 and extends to the top of the workbench 100, which can provide protection for the staff. When the clamping head 120 moves to both ends to release the clamping of the material, the baffle plate 143 can slide along the second through groove 102 to the bottom of the workbench 100.

After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
