Description

Technical Field

[0001] The invention relates to the technical field of wood processing, in particular to a lifting mechanism. Background Art

[0002] Wood processing refers to the process of processing logs through a series of processes to make various wood products or artificial boards. Wood processing mainly includes the following basic processing technologies: wood cutting, wood drying, wood gluing, wood surface decoration, etc.

[0003] The lifting mechanism used in conventional wood processing has relatively limited stability when lifting or lowering the wood. There is also a risk of the wood rolling or falling, which may cause safety accidents in the production process.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a lifting mechanism is proposed. Summary of the invention

[0005] The object of the present invention is to provide a lifting mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lifting mechanism, comprising a moving platform group and a lifting platform, wherein three groups of support rails are equidistantly arranged at the bottom of the moving platform group, and lifting frames are symmetrically and vertically installed at the left and right ends of the top of the moving platform group, and the lifting platform is connected and installed in the middle of the lifting frame, and the lifting platform comprises a loading platform, a support arm, a transmission seat, a threaded bearing seat and a ball sleeve, and the loading platform is symmetrically and horizontally installed with support arms on the left and right sides of one end of the loading platform close to the lifting frame, and a transmission seat is horizontally installed at the lower end of one side of the loading platform close to the lifting frame, and a threaded bearing seat is vertically installed in the middle of the transmission seat, and ball sleeves are vertically installed at the left and right ends of the transmission seat.

[0007] Furthermore, the mobile platform group includes a stabilizing platform, an anti-collision frame, a docking groove and an electric slider. The anti-collision frame is installed on the four sides of the stabilizing platform, and docking grooves are opened on the left and right end surfaces of the top of the stabilizing platform, and an electric slider is installed on the bottom of the stabilizing platform.

[0008] Furthermore, the anti-collision frame is fixedly connected to the stabilizing platform, and three groups of electric sliders are equidistantly arranged at the bottom of the stabilizing platform and are symmetrically arranged front to back.

[0009] Furthermore, the support rail includes a base, a slide rail, a support seat and a support rod. The slide rail is installed on the top surface of the base, and support seats are vertically installed at both ends of the base, and the top of the support seat is horizontally connected to the support rod.

[0010] Furthermore, the slide rail and the support rod are parallel to each other, and the electric slider is respectively connected to the slide rail and the support rod in a sliding manner and a keyway sliding manner.

[0011] Furthermore, the lifting frame includes a fixed seat, a support frame, a driving seat, a stable inclined frame, a guide rail, a screw and a guide rod. The support frame is vertically installed on the top of the fixed seat, and the driving seat is installed in the middle of the bottom of the support frame. The lower end of the support frame on the side away from the lifting platform is symmetrically connected to the stable inclined frame, and guide rails are vertically installed on the left and right sides of the support frame. The middle power output end of the driving seat is vertically connected to the screw, and guide rods are vertically arranged on the left and right sides of the screw.

[0012] Furthermore, the guide rod and the lead screw are parallel to each other, and the guide rod is vertically mounted inside the support frame, and the two ends of the stabilizing inclined frame are respectively welded to the support frame and the fixing seat.

[0013] Furthermore, the end of the support arm away from the loading platform is slidably connected to the guide rail by a keyway, the threaded bearing seat and the ball sleeve are threadedly connected and slidably connected to the screw and the guide rod respectively, and the surface structure of the docking groove matches the bottom surface structure of the fixed seat.

[0014] Further, the operation method is as follows: First, place the wood that needs to be lifted and moved between the left and right material placement tables. Under the operation of the driving seat in the middle of the bottom of the support frame, the lead screw connected to the middle power output end thereof rotates axially in the vertical direction, so that the lifting platform connected to the lead screw via the threaded bearing seat in the middle of the transmission seat begins to lift the wood as a whole in the vertical direction to the designated position through the sliding connection between the ball sleeve and the guide rod, and the keyway sliding connection between the support arm and the guide rail. Then, under the operation of the electric slider at the bottom of the stabilizing table, the entire lifting frame fixed to the inside of the docking groove through the fixing seat and the lifting platform with the wood placed thereon move horizontally along the surface of the slide rail and the support rod horizontally arranged between the base and the support rod, thereby realizing the overall horizontal movement.

[0015] The present invention provides a lifting mechanism, which has the following beneficial effects: 1. The present invention, through the setting of the structure of the material placement platform itself, cooperates with the support arms on both sides to be connected to the guide rail surface vertically installed on the side of the support frame by a keyway sliding connection, and at the same time, the lead screw and the guide rod are respectively vertically penetrated through the threaded bearing seat and the ball sleeve in the middle and at both ends of the transmission seat, so that when the drive seat drives the lead screw connected to the power output end thereof to perform vertical axial rotation, the material placement platform will be simultaneously translated up and down along the surface of the guide rail, the lead screw and the guide rod, so as to realize the operation of vertically lifting the wood placed on the surface of the material placement platform, thereby assisting the processing of the wood. By using the above structure, on the one hand, the lifting frame can provide the lifting platform with good structural guidance and structural driving functions, thereby ensuring the structural flexibility during vertical lifting, and on the other hand, it also provides good structural support for the mutual structural connection between the entire lifting frame and the lifting platform, thereby ensuring the stability of the structural connection between the lifting platform and the lifting frame, ensuring the safety of the device, and avoiding the rolling of the wood. At the same time, it also ensures the structural load-bearing capacity of the lifting platform itself, and can effectively lift the wood within a certain range and realize the function of structural lifting and lowering adjustment, thereby effectively assisting the processing of the wood.

[0016] 2. The present invention symmetrically installs the lifting frame connected to the lifting platform at the left and right ends of the moving platform group, and utilizes the combined use of this structure to further ensure the lifting of the wood, thereby improving the load-bearing performance of the device, and at the same time can also ensure the stability of the device when lifting or lowering the wood material as much as possible. In addition, the moving platform group and the support rails are connected and combined with each other by an electric slider at the bottom of the stable platform. Through the structural operation of the electric slider, the entire moving platform group and the lifting frame and the lifting platform on the top can be translated along the surface of the slide rail and the support rod at the same time, so as to realize the movement and adjustment of the device in the horizontal direction. The use of the above structure can further improve the operational flexibility of the device structure, and can also provide convenient movement assistance for wood processing and provide time-saving and labor-saving help for operators. In addition, the structural setting of the three groups of support rails also provides sufficient bottom support for the support rails, thereby ensuring the stability of the structure during movement.
