Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and more specifically to a material feeding hopper structure device for an edge banding machine. Background Technology

[0002] Edge banding machines are a common type of woodworking machinery, widely used for edge banding of engineered wood panels, solid wood panels, plywood, and other boards. Traditional edge banding machines rely heavily on manual feeding of boards, resulting in low automation, cumbersome operation, low efficiency, and problems such as high labor intensity for workers and untimely feeding, affecting the overall processing speed and capacity of the machine. Furthermore, due to inconsistencies in board size and position during manual feeding, feeding deviations often occur, impacting the accuracy of subsequent edge banding processes.

[0003] In the existing technology, although some edge banding machines are equipped with feeding devices, most of them have simple structures and cannot effectively adapt to the feeding requirements of different specifications of boards. They lack effective adjustment mechanisms and positioning structures, and the boards are prone to tilting or deviating during the feeding process, which affects the stability of equipment operation and processing quality. Moreover, there is still room for improvement in the degree of automation.

[0004] Therefore, designing a structurally sound, adaptable, and highly automated board feeding hopper has become a key technical issue for improving the automation level and processing efficiency of edge banding machines. Utility Model Content

[0005] In view of this, the present invention provides a material feeding hopper structure for an edge banding machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sheet metal feeding hopper structure for an edge banding machine includes an adjustable hopper assembly, a front pusher plate assembly, and a side pusher plate assembly disposed on the edge banding machine. The adjustable hopper assembly is used to store sheet metal and has a movable hopper structure, which can be adjusted to accommodate multiple sheets of sheet metal stacked therein. The adjustable hopper assembly also includes a lifting cylinder for lifting the sheet metal and a clamping cylinder for clamping the lifted sheet metal. The front pusher plate assembly includes a front pusher cylinder and a front pusher plate, used to push the sheet metal at the bottom of the movable hopper structure to the processing position. The side pusher plate assembly includes a side pusher cylinder and a side pusher plate, used to laterally limit and correct the sheet metal.

[0008] In the preferred embodiment, the adjustable hopper assembly, the front push plate assembly, and the side push plate assembly are located on one side of the processing start end of the edge banding machine, and the movement directions of the front push plate and the side push plate are perpendicular to each other in the horizontal direction.

[0009] In the preferred embodiment, the adjustable hopper assembly is provided with a workbench for connecting the edge banding machine and a hopper support frame. The movable structure of the hopper is provided with two parts, one of which is connected to a slide rail on the workbench to enable horizontal movement to adapt to different lengths of boards.

[0010] In a preferred embodiment, the movable structure of the hopper is provided with a front baffle and a rear baffle, and the front baffle and the rear baffle are provided with adjustable front-to-back and / or height adjustment mechanisms to accommodate plates of different sizes.

[0011] In the preferred embodiment, the lifting cylinder is located below the workbench and is a multi-stage telescopic cylinder used to adapt to the lifting requirements of plates of different thicknesses.

[0012] In a preferred embodiment, the side pusher plate assembly is provided with a limiting buffer device, a side guide shaft, and a side support frame. The side pusher plate is connected to the side guide shaft, and the limiting buffer device includes a buffer spring or a damper.

[0013] In a preferred embodiment, the front push plate assembly is provided with a front push guide shaft and a front push support frame, wherein the front push plate is connected to the front push guide shaft.

[0014] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0015] By incorporating multiple structural units such as adjustable hoppers, front-push plates, and side-push plates, along with a control system, the system achieves automated cycling of multiple sheet material storage, as well as sheet material lifting, clamping, pushing, and limit correction actions. This significantly reduces manual operation and improves production efficiency. The adjustable hopper structure features a movable hopper mechanism and adjustment system, allowing for flexible adjustments based on sheet material dimensions (length, width, height), enhancing the equipment's applicability and meeting diverse processing needs. The use of multi-stage lifting cylinders in conjunction with clamping cylinders ensures precise control of sheet material lifting and release, guaranteeing smooth detachment and pushing of individual sheets, improving feeding stability. The combined front and side push mechanisms ensure accurate sheet material positioning before processing, preventing processing deviation. The rational structural design and relatively low manufacturing cost, coupled with significantly reduced manual intervention, effectively alleviate labor pressure and enhance the company's automation level and competitiveness. It effectively solves the problems of low efficiency, large errors, and poor adaptability inherent in traditional edge banding machines during the feeding stage. Attached Figure Description

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] Please refer to the sheet metal feeding hopper structure of an edge banding machine. Figure 1-3 This invention includes an adjustable hopper assembly 100, a front pusher plate assembly 200, and a side pusher plate assembly 300, all located within the edge banding machine. Edge banding machines are commonly used in woodworking machinery processing to band the edges of engineered wood, solid wood, and plywood boards. Typically, the boards are fed into the edge banding machine for various processing steps. This invention optimizes the board feeding stage at the very front of the edge banding machine to achieve automated feeding. The attached diagram only shows the frame and conveyor belt of the edge banding machine. The adjustable hopper assembly 100 stores the boards and includes a movable hopper structure 110. By adjusting the movable hopper structure 110, multiple boards can be stacked within it for subsequent feeding. The stacked boards are placed in the movable hopper structure 110 for sequential feeding. The adjustable hopper assembly also includes a lifting cylinder 120 for lifting the plates and a clamping cylinder 150 for clamping the lifted plates. The stacked plates are all lifted by the lifting cylinder 120, and the clamping cylinder 150 applies a horizontal pushing force to several plates from the second bottom to the top, clamping the plates to prevent them from falling. Then the lifting cylinder 120 falls, and the bottom plate, which was not clamped, falls down as well. The front pusher assembly 200 includes a front pusher cylinder 210 and a front pusher plate 220. The front pusher cylinder 210 drives the front pusher plate 220 to move back and forth, pushing the bottom plate in the movable structure 110 of the hopper to the processing position. The side pusher assembly 300 includes a side pusher cylinder 310 and a side pusher plate 320, used to laterally limit and correct the plate. The cylinders are driven sequentially by the control system to achieve the following automatic cycle: storing plate → lifting plate → clamping plate → front pusher cylinder feeding plate → side pusher plate limiting → front pusher cylinder and side pusher cylinder resetting. Through the above-mentioned hopper structure device operation steps, more accurate and efficient plate production capacity is achieved, reducing construction costs and reducing excessive reliance on manual labor.

[0025] Furthermore, the adjustable material bin assembly 100, the front push plate assembly 200, and the side push plate assembly 300 are located on one side of the processing start end of the edge banding machine. The movement directions of the front push plate 220 and the side push plate 320 are perpendicular to each other in the horizontal direction. The three parts are linked together and located at the start end of the edge banding machine to realize material storage, feeding, and limit correction, ensuring efficient feeding and accurate positioning. This utility model shares a control system with the edge banding machine. The control system includes a programmable logic controller (PLC) to coordinate the action sequence and timing of each actuator.

[0026] Furthermore, the adjustable hopper assembly 100 is equipped with a workbench 130 for connecting the edge banding machine and a hopper support frame 140. The adjustable hopper assembly 100 is supported on the ground by the hopper support frame 140 for stable operation. There are two movable hopper structures 110. The one on the left is fixed, while the one on the right is horizontally movable via a slide rail 131 on the connecting workbench 130 to accommodate different lengths of boards. Generally, the movable hopper mechanism 110 on the right is also equipped with a clamping screw that can be fixed in position. When it is necessary to adjust the distance between the two movable hopper mechanisms 110 according to the length of the board, after loosening the clamping screw, the right part is horizontally moved to the corresponding position and then the clamping screw is tightened. The movable structure 110 of the hopper is provided with a front baffle 111 and a rear baffle 112. The main structure of the movable structure 110 itself has a vertical plate structure. The front baffle 111 and the rear baffle 112 are located inside the plate structure. The front baffle 111 and the rear baffle 112 form a space that can accommodate the plates. In addition, the top of the front baffle 111 and the rear baffle 112 are also provided with an outwardly expanding inclined structure to facilitate the placement of the plates. The workbench 130 supports the stacked plates. The bottom of the front baffle 111 and the rear baffle 112 is a certain distance away from the workbench 130 to ensure that the bottom plate can be pushed out. The front baffle 111 and the rear baffle 112 are provided with an adjustable mechanism 113 that can be adjusted forward and backward or / and height. In this embodiment, the adjustable mechanism 113 is a clamping screw with a handle. The front baffle 111 can be adjusted in height, and the rear baffle 112 can be adjusted forward and backward. After loosening the clamping screw, the position of the front baffle 111 and the rear baffle 112 can be adjusted. Tightening it will complete the adjustment. It can be adapted to different sizes of boards, so that boards of different sizes can be placed inside, which is highly flexible. The lifting cylinder 120 is located below the worktable 130. The lifting cylinder 120 is a multi-stage telescopic cylinder used to adapt to the lifting requirements of plates of different thicknesses. Since the clamping cylinder 130 is horizontally fixed on the movable structure 110 of the hopper and at a certain distance from the worktable 130, when the plate is lifted, the clamping height of the clamping cylinder 130 remains unchanged. Therefore, the multi-stage lifting can ensure that plates of different thicknesses can be clamped down to the second and above from the bottom. After the lifting cylinder 120 falls, only the bottom plate is not clamped down and falls down with it, and can then be pushed out smoothly.

[0027] Furthermore, the side push plate assembly 300 is provided with a limiting buffer device 330, a side guide shaft 340 and a side support frame 350. The side push plate 320 is connected to the side guide shaft 340 to ensure stable movement. The limiting buffer device 330 includes a buffer spring. The limiting buffer device 330 is used to prevent the impact force during the side push process from causing positional displacement or damage to the plate. The side support frame 350 supports the side push plate assembly 300. Multiple side guide shafts 340 are provided, and fixed sheet metal is connected to both sides. Two fixed sheet metals are respectively set on the side support frame 350 and the edge banding machine. The side push cylinder 310 is fixed on the fixed sheet metal on the side support frame 350. The push rod of the side push cylinder 310 is connected to the side push plate 320. In addition, the left side of the edge banding machine is provided with a limiting sheet metal corresponding to the side push plate 320. When the plate is pushed forward, the side push cylinder 310 pushes out the push rod. The side push plate 320 and the limiting sheet metal simultaneously abut against the plate, keeping it in a positive state and pushing it out to the processing position. The front push plate assembly 200 is provided with a front push guide shaft 230 and a front push support frame 240. The front push plate 220 is connected to the front push guide shaft 230, and the front push support frame 240 supports the front push plate assembly 200 as a whole to ensure its stable placement. The front push guide shaft 230 ensures the stability of the movement of the front push plate 220. In this embodiment, the front push cylinder 210 is set in the opposite direction. Its push rod is connected to the front push plate 220 through a connecting rod. When the cylinder pushes out the push rod, the front push plate 220 retracts. When the cylinder push rod retracts, the front push plate 220 pushes out and pushes the plate to feed. However, the setting direction of the front push cylinder 210 is not limited to this embodiment. The bottom end of the front push plate 220 is higher than the worktable 130, and the top end is lower than the bottom end of the front baffle 111 and the rear baffle 112 to ensure that the plate can be pushed smoothly.
