Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and more specifically to an adjustable lifting flexible cutting and feeding tape assembly structure device. Background Technology

[0002] Edge banding machines, as an important component of woodworking machinery, are mainly used to band the edges of boards to improve the overall aesthetics and durability of the product. In the edge banding process, the conveying and cutting of the edge banding tape is particularly critical, as its stability and precision directly affect the quality of the edge banding. Existing cutting and feeding assemblies generally have several problems. The height of the conveyor chain blocks varies between different edge banding machine models, and existing devices are mostly fixed-height structures, requiring customization for different equipment and increasing manufacturing and operating costs. Traditional cutting structures are mostly rigid connections, resulting in abrupt cutting movements that easily cause rough edges or positional deviations in the edge banding tape. The lack of an effective anti-backflow mechanism during tape feeding leads to tape retraction during intermittent feeding, affecting processing continuity. Existing devices cannot accurately guide edge banding tapes of different thicknesses or widths, easily causing tape offset or misalignment. Utility Model Content

[0003] In view of this, the present invention provides an adjustable lifting flexible cutting conveyor belt assembly structure device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable and height-adjustable flexible cutting and feeding assembly includes a cutting worktable; a cutting fixing seat fixedly installed on an edge-sealing machine, the cutting worktable being connected to the cutting fixing seat via a tabletop fixing seat, and its height being adjustable via a slide rail, guide slider, and table height adjustment shaft; and a flexible cutting structure mounted on the cutting worktable, including a cutting blade, a cutting cylinder, and a cutting cylinder fixing seat, the cutting cylinder fixing seat being flexibly connected to the worktable via an elastic connecting component, used to drive the cutting blade... Horizontal cutting; a motor and reducer located below the cutting worktable to drive the rotation of the drive shaft protruding from the worktable; a feeding cylinder and feeding roller located on the cutting worktable, the feeding roller pressing against the drive shaft to clamp the edge banding tape, thus conveying the edge banding tape; a first guide plate and a second guide plate located on the worktable to guide the movement of the edge banding tape; an anti-reverse structure located on the worktable, including an anti-reverse roller that can rotatably press against the first guide plate to prevent the edge banding tape from reversing.

[0006] In the preferred technical solution, the anti-backflow structure includes a fixed column that is vertically fixed to the cutting workbench. A support bar is rotatably installed on the fixed column. A spring is provided between the support bar and the fixed column. An anti-backflow roller is provided at one end of the support bar. The roller is pressed against the first guide belt baffle under the action of the spring.

[0007] In the preferred technical solution, the cutting cylinder fixing seat in the flexible cutting structure is connected to the cutting workbench through a rotatable connecting block. The rear of the connecting block is provided with two compression springs and connecting screws. The screws are fixed to the fixing block installed on the workbench, so that the cutting blade forms a buffer swing structure.

[0008] In the preferred technical solution, the tape feeding cylinder is set on the cutting workbench, and the bottom end is connected to the tape feeding roller. When the cylinder is activated, the tape feeding roller approaches the drive shaft and clamps the edge sealing tape between them. The drive shaft drives the edge sealing tape to be conveyed.

[0009] In the preferred technical solution, a guide belt height limiter is provided on the cutting workbench, and two guide shafts are connected to its bottom to realize the vertical lifting and lowering of the height limiter; the guide belt height limiter is set near the first guide belt baffle to limit the height of the edge banding, and its height is adjusted by the first guide belt height adjustment shaft that runs through the cutting workbench to accommodate edge banding of different specifications.

[0010] In the preferred technical solution, the top of the guide belt height limiting seat is provided with a rotating head connected to the first guide belt height adjusting shaft and a connecting rod. The other end of the connecting rod is connected to the second guide belt height adjusting shaft. The bottom of the second guide belt height adjusting shaft is provided with a guide belt slot seat. The bottom of the guide belt slot seat is provided with a groove for matching the shape of the edge banding. When the guide belt height limiting seat is raised and lowered, it drives the second guide belt height adjusting shaft to rise and fall synchronously, thereby realizing the height limiting and guidance of edge banding with different thicknesses.

[0011] In the preferred technical solution, the table height adjustment shaft and the guide slider are used to adjust the height of the cutting worktable, thereby adapting to the height of the conveyor chain blocks of different edge banding machines and improving the versatility of the device.

[0012] In the preferred technical solution, the motor and the reducer are connected by a coupling, and the output end of the reducer is connected to the drive shaft to achieve low-speed, high-torque output of the drive shaft.

[0013] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0014] By incorporating a height-adjustable shaft and guide slider, the cutting worktable can be adjusted vertically to accommodate the conveyor chain heights of different edge banding machine models, solving the customization requirements of traditional equipment and significantly improving the device's versatility and adaptability. The anti-backflow roller, under spring action, constantly presses against the edge banding, effectively preventing it from slipping back during conveying due to loosening or intermittent movement, thus improving the continuity and stability of feeding. The elastically connected cutting cylinder fixing seat provides the cutting blade with a oscillating buffer capability, allowing for a gentler cut of the edge banding, avoiding issues such as cutting position deviation and rough edges, and improving the aesthetics of the edge banding. Adjustable guide belt height limit seats and guide belt clamping slots ensure accurate positioning and guidance of edge banding of different widths and thicknesses, effectively reducing edge banding deviation, bending, or jamming, and improving the overall processing accuracy and stability of the machine.

[0023] An adjustable lifting flexible cutting conveyor belt assembly structure, such as... Figure 1-3 As shown, the system includes modules such as a cutting worktable 1, a cutting fixing seat 2, a flexible cutting structure, a feeding structure, an anti-reverse structure, a guide belt height limiting structure, a motor drive structure, and a guide structure. The cutting worktable 1 is fixedly installed on the cutting fixing seat 2 on the edge banding machine via a tabletop fixing seat 18. The cutting worktable 1 achieves overall height adjustment through a slide rail, a guide slider 20, and a table height adjustment shaft 7, thereby adapting to the installation height of the conveyor chain blocks of different models of edge banding machines and improving versatility. The tabletop fixing seat 18 includes two plates connected to the bottom of the cutting worktable 1. One plate connects the height adjustment shaft 7 and the cutting fixing seat 2, and the other plate connects to the cutting fixing seat 2 via a slide rail and a guide slider 20 to achieve height adjustment.

[0024] Furthermore, a flexible cutting structure is provided on the cutting worktable 1, including a cutting cylinder 11, a cutting blade 4, and a cutting cylinder fixing seat 3. The cutting cylinder fixing seat 3 is flexibly connected to the worktable 1 via an elastic connecting assembly, such as... Figure 2As shown, this connection method uses a rotatable connecting block 13. Two compression springs and connecting screws are located at the rear of the connecting block 13, enabling the cutting blade 4 to buffer swaying at the moment of cutting, improving the flexibility and precision of the edge banding cutting. A motor 5 and a reducer 6 are installed below the cutting worktable 1, connected by a coupling. The reducer output is connected to the protruding drive shaft 15 on the worktable, achieving stable low-speed, high-torque output from the drive shaft 15. A tape feeding structure is also provided on the worktable, including a tape feeding cylinder 14 and a tape feeding roller 141. When the cylinder actuates, it drives the tape feeding roller 141 to press vertically against the drive shaft 15, clamping the edge banding. The drive shaft rotates to transport the edge banding. To ensure the linear stability of the edge banding during transport, a first guide baffle 12 and a second guide baffle 17 are provided on the worktable for lateral guidance of the edge banding, preventing lateral deviation. Simultaneously, an anti-reverse conveyor structure 16 is provided, which includes a fixed column 161, a support bar 162, a spring 163, and an anti-reverse roller 164. Under the action of the spring, the anti-reverse roller presses against the first guide belt baffle 12, which can effectively prevent the sealing belt from reversing and enhance the continuity of conveying.

[0025] Furthermore, to accommodate the use of edge banding tapes of different thicknesses, the cutting workbench 1 is equipped with a guide tape height limiting seat 22, which is supported by two guide shafts 8 and can achieve vertical lifting and lowering. The guide tape height limiting seat is located near the first guide tape baffle 12, and its bottom limiting edge is used to control the vertical height of the edge banding tape. To achieve precise height limiting, a first guide tape height adjusting shaft 9 is provided on the top of the guide tape height limiting seat 22, and a rotating head is connected for adjustment. The top of the height limiting seat is also connected to a second guide tape height adjusting shaft 10 via a connecting rod. A guide tape slot seat 21 is provided at the bottom of the shaft 10. The bottom of the slot seat has a replaceable groove for fitting and embedding with the bottom of edge banding tapes of different thicknesses, thereby achieving the dual purpose of height limiting and guiding. When the height limiting seat 22 is raised and lowered, the second guide tape height adjusting shaft 10 and the guide tape slot seat 21 are also raised and lowered synchronously, so that edge banding tapes of different thicknesses can always be accurately limited in height and embedded in the groove for guidance and conveying.

[0026] Furthermore, during installation and use, the operator needs to fix this cutting and feeding assembly onto the edge banding machine, and adjust the cutting worktable 1 to the corresponding height of the edge banding machine chain block using the adjusting shaft 7. Then, the edge banding to be processed is guided sequentially through the anti-reverse structure 16, the drive shaft 15, the cutting structure, and then through the second guide belt baffle 17, allowing it to enter the processing track. Based on the thickness of the edge banding, the height positions of the guide belt height limit seat 22 and the second guide belt height adjusting shaft 10 are adjusted by rotating the adjusting head, and the edge banding is embedded into the corresponding groove of the guide belt slot seat 21, completing the height limitation and positioning. After starting the motor 5, the drive shaft 15 begins to rotate, and the feeding cylinder 14 actuates, causing the feeding roller 141 to press the edge banding against the drive shaft 15, thereby achieving uniform speed feeding of the edge banding. When the edge banding tape reaches the predetermined cutting position, the control system activates the cutting cylinder 11, driving the cutting blade 4 to perform a horizontal cutting action. Combined with the flexible connection structure, this achieves a smooth and precise cut to the edge banding tape. After cutting, the edge banding tape continues to be conveyed forward to the next workstation.

[0027] Furthermore, compared to existing cutting and feeding assemblies on the market, this utility model adds the following key functional modules to the original conveying and cutting structure: Anti-reverse structure: A spring-loaded anti-reverse roller effectively prevents the edge banding tape from reversing, improving feeding stability; Workbench height adjustment function: Allows the equipment to be compatible with edge banding machines with different conveyor chain heights, enhancing adaptability; Guide belt height limit + guide groove structure: Adapts to different edge banding tape specifications, improving positioning accuracy; Flexible cutting structure: Features a cutter installation method with buffered swing, improving cutting stability and reducing errors. Through these improvements, not only is the equipment's versatility and production efficiency enhanced, but the stability of the edge banding effect is also further optimized, overcoming the long-standing problems of equipment compatibility difficulties and unstable edge banding in the edge banding industry.
