Description

Technical Field

[0001] This invention relates to the field of wood processing equipment technology, and in particular to an edge banding machine with a follow-up gripper. Background Technology

[0002] Currently, after wood panels are cut and their surfaces are processed, to prevent burrs and sawdust from being sharp and to improve the appearance, edge banding is usually applied to the four ends of the panels, i.e., edge sealing. Smooth, thin sheets of plastic (edge ​​banding strips, edge binding strips) are adhered to the ends of the panels, and any excess material is trimmed off to ensure the edge banding is flush with the panel ends.

[0003] Existing edge banding and edge-wrapping machines, when performing edge banding on boards, require the boards to be continuously conveyed backward on the conveyor line, resulting in a moving state. When the edge banding strip is applied to the board's end face, a certain amount of pressure is applied to ensure adhesion. Therefore, when the edge banding machine's bonding component applies pressure to the edge banding strip, it pushes the board, easily causing the board's position to shift, affecting the edge banding process and subsequent edge-wrapping, cutting, and chamfering processes. While existing technology includes guide rollers directly above the conveyor line to assist in conveying the board backward, the friction provided by the conveyor line to the board is insufficient. During edge banding application, the indirect pressure from the bonding component on the board easily causes positional shifts. This is especially true when the board's lateral width is narrow, as the number of guide rollers contacting its upper surface is small, resulting in low friction between the board and the conveyor line and guide rollers. This further exacerbates the positional shift when the bonding component indirectly presses against the board.

[0004] In view of the above problems, this application provides an edge banding machine with a follow-up gripper. When completing the process of bonding the edge banding strip to the end face of the board, a gripper is set to hold the board. While holding the board, the gripper is conveyed backward synchronously with the conveyor belt. During this process, the bonding component applies a certain pressure to the edge banding strip, so that it is bonded to the end face of the board. The bonding component indirectly squeezes the board, but the position of the board will not shift at this time because the board has been held and limited by the gripper. Summary of the Invention

[0005] The purpose of this invention is to provide an edge banding machine with a follow-up gripper. Its design is simple and reasonable, and its operation is stable and reliable. When completing the process of bonding the edge banding strip to the end face of the board, the gripper holds the board while it is conveyed backward synchronously with the conveyor belt. During this process, the bonding component applies a certain pressure to the edge banding strip and indirectly squeezes the board, so that the edge banding strip is bonded to the end face of the board. However, the position of the board will not shift at this time because the board has been held and limited by the gripper.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0007] An edge banding machine with a follow-up gripper includes a frame, a conveying assembly, a sheet material conveying auxiliary assembly, a strip (edge ​​banding strip) application assembly, a sheet material positioning follow-up gripper, an edge banding strip cutting assembly, and a chamfering processing assembly;

[0008] The frame is horizontally arranged and equipped with a conveying assembly. The sheet metal processing components, such as the strip application assembly, chamfering assembly, and edge banding cutting assembly, are sequentially arranged on one side of the conveying assembly. The sheet metal positioning and follow-up gripper is located on the opposite side of the strip application assembly.

[0009] The edge banding strip assembly includes an edge banding strip feeding rack, an edge banding strip guide and traction component, and a pressing and clamping assembly. The edge banding strip feeding rack is used to hold the edge banding strip rolls, and the edge banding strip guide and traction component is located on its right side to guide the conveying direction of the edge banding strip. The pressing and clamping assembly is located on the right side of the edge banding strip guide and traction component, which is used to press the edge banding strip against the end face of the board, so it will squeeze the edge banding strip and indirectly squeeze the end face of the board. The pressing and clamping assembly includes a clamping cylinder, a vertical shaft, and a pressure-applying guide roller. The clamping cylinder is horizontally set, and its output end is connected to the vertically set vertical shaft. The pressure-applying guide roller is sleeved on the vertical shaft.

[0010] The plate positioning and follow-up gripper includes two magnetic dipole guide rodless cylinders, a clamping cylinder, an inlet micro switch, an outlet micro switch, and a control circuit. The two magnetic dipole guide rodless cylinders are horizontally and relatively spaced apart, respectively located on the upper and lower sides of the conveyor belt. A clamping cylinder is vertically mounted on each of the magnetic dipole guide rodless cylinders. The two clamping cylinders are aligned with each other. When the clamping cylinders extend simultaneously, they can clamp the upper and lower surfaces of the plate. The two magnetic dipole guide rodless cylinders drive the clamping cylinders to move left and right, clamping and conveying the plate to the right. The inlet and outlet micro switches are located at the left and right ends of the clamping cylinder's magnetic dipole guide rodless cylinder. The magnetic dipole guide rodless cylinder, clamping cylinder, inlet micro switch, and outlet micro switch are electrically connected to the control circuit.

[0011] Once the entire sheet material has passed through the inlet microswitch, the swing arm resets and quickly sends signals to the clamping cylinder and the rodless cylinder of the magnetic dipole guide rail. The clamping cylinder clamps the upper and lower surfaces of the sheet material, and the rodless cylinder of the magnetic dipole guide rail moves the sheet material to the right. When the bottom of the rodless cylinder of the magnetic dipole guide rail touches and slides past, it quickly sends signals to the clamping cylinder and the rodless cylinder of the magnetic dipole guide rail. The clamping cylinder releases the upper and lower surfaces of the sheet material, and the rodless cylinder of the magnetic dipole guide rail moves to the left and resets.

[0012] The inlet micro switch includes a rocker arm, a pin, and a guide bearing; the outlet micro switch has the same structure as the inlet micro switch. The pin is horizontally positioned, and the rocker arm is vertically positioned, with its middle section sleeved on the pin and hinged to it, allowing it to rotate around the pin. The top of the rocker arm is hinged to the guide bearing.

[0013] Above the conveying assembly is a sheet metal conveying auxiliary assembly; the sheet metal conveying auxiliary assembly includes a lifting frame, a pressure plate, guide wheels, a lifting motor, and a transmission linkage; the lifting frame is horizontally positioned, with a horizontally positioned pressure plate at its bottom, and several guide wheels on both sides of the pressure plate. A lifting motor is located at the top of the lifting frame, driving the lifting frame to rise and fall. The lifting motor is connected to a horizontally positioned transmission linkage, with worm gears fitted at both ends of the transmission linkage. The worm gears mesh with a worm wheel, which is fixed to a lead screw, driving the lead screw to rotate; the lower end of the lead screw is connected to the lifting frame via a lifting sleeve, with the lead screw engaging with the lifting sleeve for transmission. The lifting motor synchronously splits its power into two parts through the transmission linkage, driving the left and right ends of the lifting frame to rise and fall synchronously.

[0014] The edge banding strip cutting assembly is a component that cuts off excess dimensions of the edge banding strip. It is existing technology and will not be described in detail here.

[0015] The chamfering assembly is a component used to grind and chamfer the edges of the sheet metal. This is existing technology and will not be elaborated upon here.

[0016] The beneficial effects of this invention are:

[0017] Its design is simple and reasonable, and its operation is stable and reliable;

[0018] When the edge banding strip is bonded to the end face of the board, the clamp holds the board while it is conveyed backward synchronously with the conveyor belt. During this process, the bonding component applies a certain pressure to the edge banding strip and indirectly squeezes the board, so that the edge banding strip is bonded to the end face of the board. However, the position of the board will not shift at this time because the board has been clamped and limited by the clamp. Attached Figure Description
