The traditional method is generally for workers to use tools such as claw hammers and crowbars to perform dismantling operations.

[0003] At present, during the operation of the building formwork nail removing device, the screw position can only be checked manually and the nails can be removed manually, which is time-consuming, labor-intensive and has low work efficiency. Therefore, it is necessary to propose an automatic nail removing device for building formwork to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0015] The following will be combined with specific embodiments and attached Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0016] An automatic nail removing device for building templates includes a fixing frame 2. The fixing frame 2 mainly plays a role similar to a gantry. A conveyor belt 1 is provided at the bottom of the fixing frame 2. The conveyor belt 1 is used to convey the template and cooperate with the lateral positioning of the template. When the template is placed on the conveyor belt 1, the lateral adjustment function can be achieved by controlling the front and left and right movement of the conveyor belt 1.

[0017] The fixed frame 2 is a ∏-shaped structure, and a slide groove is opened on its top along the direction perpendicular to the running direction of the conveyor belt 1. A hollow tube 3 is slidably connected in the slide groove. A screw rod 22 is threadedly connected on the fixed frame 2. The setting direction of the screw rod 22 is consistent with the opening direction of the slide groove. A sleeve 24 is threadedly connected on the screw rod 22. The sleeve 24 is fixedly connected to the hollow tube 3. By rotating the screw rod 22, the sleeve 24 can slide along the slide groove together with the hollow tube 3, thereby realizing the longitudinal movement adjustment of the hollow tube 3. A controller 21 is provided on the outer side of the fixed frame 2. The controller 21 is the prior art. The controller 21 is electrically connected to the conveyor belt 1, and can control the conveyor belt 1 to run forward or reverse, and automatically adjust the position of the template on the conveyor belt 1. A motor 23 is provided on the hollow tube 3, and the motor 23 is electrically connected to the controller 21, so that the controller 21 can control the motor 23 to rotate forward or reverse, thereby adjusting the longitudinal movement of the sleeve 24 and the hollow tube 3.

[0018] A traction electromagnet 31 is fixedly connected in the hollow tube 3. The traction electromagnet 31 is fixedly connected to the upper part of the inner hole of the hollow tube 3. The traction electromagnet 31 is a prior art. The iron core in the traction electromagnet 31 can slide up and down. An electromagnetic plate 32 is fixedly connected to the bottom end of the iron core. A nail head 33 is fixedly connected to the bottom of the electromagnetic plate 32. The nail removing head 33 is a prior art. The nail removing head 33 can be engaged between the steel nail head and the template. The steel nail can be pulled out of the template by giving the nail removing head 33 an upward pulling force. A metal detector 34 is fixedly connected to the nail removing head 33, which can detect and identify the position of the steel nail on the template. The metal detector 34 and the traction electromagnet 31 are both electrically connected to the controller 21. The metal detector 34 will transmit the detected steel nail position signal to the controller 21. Then the controller 21 controls the conveyor belt 1 and the motor 23 to move the nail removing head 33 and the wooden board on the conveyor belt 1 to the corresponding positions, so as to facilitate nail removal.

[0019] A positioning plate 4 is fixedly connected to the bottom end surface of the hollow tube 3. The positioning plate 4 is a rectangular structure. A hole is opened in the middle of the positioning plate 4. The hole is the same size as the gap of the hollow tube 3, so that the iron core inside the hollow tube 3 can move up and down without being hindered. Electric cylinders 41 are provided at the four corners of the positioning plate 4. Through holes are opened on the positioning plate 4 corresponding to the electric cylinders 41. The electric cylinders 41 can be extended and retracted downward. The electric cylinders 41 are electrically connected to the controller 21, so that the controller 21 can control the output end of the electric cylinder 41 to move up and down. The bottom end of the output end of the electric cylinder 41 is fixedly connected with a pressing plate 42, and the bottom end of the pressing plate 42 is fixedly connected with a rubber pad. The controller 21 can control the output end of the electric cylinder 41 to move downward so that it is pressed on the template below to facilitate the start-up operation of the steel nails on the wooden board. The rubber pad can prevent the template from slipping.

[0020] An electric slide rail 5 is provided on the bottom end surface of the positioning plate 4, and an electric slider 51 is slidably connected to the electric slide rail 5. The above are all prior arts. The electric slider 51 is electrically connected to the controller 21, and the controller 21 can control the electric slider 51 to move on the electric slide rail 5. A push plate 52 is fixedly connected to the bottom end of the electric slider 51. When the iron core moves to the highest point, the bottom end surface of the push plate 52 contacts the top end surface of the nail removing head 33. The sliding of the electric slider 51 can push the steel nails on the nail removing head out of the nail removing head 33. A nail collecting box 6 is provided on the inner side of the fixed frame 2. The position of the nail collecting box 6 corresponds to the nail removing head 33. The horizontal height of the nail collecting box 6 is lower than the nail removing head 33 at the highest position, so that the push plate 52 can push the steel nails into the nail collecting box 6.

[0021] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0022] In the present utility model, "up", "down", "left", "right", "front" and "back" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0023] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
