Description

Technical fields:

[0001] This utility model relates to the field of tape feeding technology for edge banding machines, and in particular to a tape feeding device for edge banding machines. Background technology:

[0002] In the existing technology, most of the tape feeding devices used for edge banding machines are still single-channel tape feeding devices. The single-channel tape feeding device has the following problems when in use: not only does it require stopping the machine to replace the tape with a new one after the tape is used up, resulting in low tape replacement efficiency and a significant reduction in overall production efficiency, but it also requires stopping the machine to replace the tape when faced with the demand for tapes of different materials and / or colors, which takes a long time. Utility Model Content:

[0003] The purpose of this invention is to provide a tape feeding device for edge banding machines that addresses the shortcomings of existing technologies. This device can not only quickly replace used tape for continuous production, greatly improving tape changing efficiency and overall production efficiency, but also simultaneously load tapes of various materials and / or colors, and quickly switch between providing tapes of different materials and / or colors according to different edge banding requirements of the boards.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tape feeding device for an edge banding machine, comprising a tape feeding worktable, wherein the tape feeding worktable is sequentially provided with a tape distribution conveyor, a tape guide plate assembly, a main tape conveyor, and a tape cutting device along the tape conveying direction; the tape distribution conveyor is used to convey one of the tapes to the position of the main tape conveyor or to retract the tape located at the position of the main tape conveyor, wherein the tape is guided and conveyed to the position of the main tape conveyor via the tape guide plate assembly; the main tape conveyor is used to feed out or retract one of the tapes; and the tape cutting device is used to cut the tape.

[0005] A further improvement to the above scheme is that the material conveying device includes several dual-channel material conveying devices. Each dual-channel material conveying device includes a material conveying base set on the conveying workbench, a material conveying drive wheel rotatably connected to the material conveying base in the vertical direction, a servo power mechanism for driving the material conveying drive wheel to rotate, two material conveying driven wheels slidably connected to both sides of the material conveying drive wheel, and two driven wheel sliding power mechanisms for driving the two material conveying driven wheels to slide. The servo power mechanism is set on the material conveying base, and the output end of the servo power mechanism drives and connects to the material conveying drive wheel.

[0006] A further improvement to the above scheme is that the dual-channel material belt conveyor also includes two material belt anti-reverse components for preventing the material belt from retracting. The two material belt anti-reverse components each include an anti-reverse post disposed behind the material belt conveyor drive wheel, an anti-reverse wheel slidably connected to one side of the anti-reverse post, and an anti-reverse power mechanism for driving the anti-reverse wheel to slide.

[0007] A further improvement to the above scheme is that the driven wheel sliding power mechanism and the anti-reverse power mechanism are of the same structure. The driven wheel sliding power mechanism includes a swing shaft rotatably connected to the material conveyor base in a vertical direction, a swing block disposed on the swing shaft, a driven wheel shaft disposed on one end of the swing block, an anti-reverse shaft disposed on the other end of the swing block, and a push-pull cylinder. The push-pull cylinder is disposed on the material conveyor base, and the output end of the push-pull cylinder drives and connects to the swing block. The driven wheel of the material conveyor is sleeved on the driven wheel shaft, and the anti-reverse wheel is sleeved on the anti-reverse shaft. When the push-pull cylinder drives the swing block to swing forward, the driven wheel of the material conveyor moves closer to the driving wheel of the material conveyor, and the anti-reverse wheel moves away from the anti-reverse post. When the push-pull cylinder drives the swing block to swing backward, the driven wheel of the material conveyor moves away from the driving wheel of the material conveyor, and the anti-reverse wheel moves closer to the anti-reverse post.

[0008] A further improvement to the above solution is that the material conveying device further includes a material belt limiting component, which includes a material belt limiting frame and multiple material belt limiting blocks disposed on the material belt limiting frame. The bottom of the material belt limiting blocks has a U-shaped structure and the opening faces downward.

[0009] A further improvement to the above solution is that the height position of the material strip limiting block on the material strip limiting frame is adjustable.

[0010] A further improvement to the above scheme is that the main conveyor belt device includes a main conveyor drive wheel rotatably connected to the conveyor belt workbench in the vertical direction, a main conveyor rotation power mechanism for driving the main conveyor drive wheel to rotate, a main conveyor driven wheel slidably connected to one side of the main conveyor drive wheel, and a main conveyor sliding power mechanism for driving the main conveyor driven wheel to slide.

The main conveyor sliding power mechanism is set on the conveyor belt workbench, and its output end is connected to the main conveyor driven wheel.

[0011] A further improvement to the above solution is that the strip cutting device includes a strip cutting frame disposed on the strip feeding worktable, a cutting block slidably connected to the strip cutting frame in the horizontal direction, and a cutting power mechanism for driving the cutting block to slide. The cutting power mechanism is disposed on the strip cutting frame, and the output end of the cutting power mechanism drives the cutting block.

[0012] A further improvement to the above solution is that the present invention also includes a belt pressing device for pressing the top of the belt downwards.

[0013] A further improvement to the above solution is that the pressing device includes a pressing block slidably connected to the top of the feeding table in a vertical direction, and a pressing lifting power mechanism for driving the pressing block to slide. The pressing lifting power mechanism is set on the feeding table, and the output end of the pressing lifting power mechanism drives and connects to the pressing block.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a tape feeding device for an edge banding machine, including a tape feeding worktable. The tape feeding worktable is sequentially provided with a tape distribution conveyor, a tape guide plate assembly, a main tape conveyor, and a tape cutting device along the tape conveying direction. The tape distribution conveyor is used to convey one of the tapes to the main tape conveyor or to retract the tape located at the main tape conveyor. The tape is guided to the main tape conveyor via the tape guide plate assembly. The main tape conveyor is used to feed or retract one of the tapes. The tape cutting device is used to cut the tape.

[0015] When feeding the edge banding machine using this invention, multiple parallel material belts are pre-loaded. A material distribution conveyor transports one of these belts to the main material belt conveyor. The belt then passes through a guide plate assembly and is subsequently discharged from the main material belt conveyor, completing the feeding process. When one belt runs out and needs to be replaced, the other material belt is simply transported to the main material belt conveyor via the material distribution conveyor. The main material belt conveyor then discharges the currently stored belt, allowing for quick replacement of the used belt and continued production. The invention also allows for switching between belts of different materials and / or colors. First, the current material strip is cut by the material strip cutting device. Then, the material strip of the current material and / or color is retrieved from the main material strip conveyor by the material strip conveyor. Next, the material strip of the required material and / or color is conveyed to the main material strip conveyor by the material strip conveyor. Finally, the material strip currently delivered to the main material strip conveyor is delivered out by the main material strip conveyor. This allows for rapid switching between different materials and / or colors of material strips. Compared to existing single-channel conveyor devices for edge banding machines, this invention not only allows for rapid replacement of used material strips for continuous production, greatly improving belt changing efficiency and overall production efficiency, but also allows for simultaneous loading of multiple materials and / or colors of material strips. It can quickly switch between providing different materials and / or colors of material strips according to different edge banding requirements of the board. Attached image description:

Detailed implementation method:

[0024] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-7As shown, this utility model includes a belt feeding workbench 1. The belt feeding workbench 1 is sequentially equipped with a material distribution belt conveyor 2, a belt guide plate assembly 4, a main belt conveyor 5, and a belt cutting device 6 along the belt conveying direction. The material distribution belt conveyor 2 is used to convey one of the various belts to the main belt conveyor 5 or to retract the belt located at the main belt conveyor 5. The belt is guided to the main belt conveyor 5 via the belt guide plate assembly 4. The main belt conveyor 5 is used to feed out one of the various belts. Or retrieve; the material strip cutting device 6 is used to cut the material strip; when feeding the edge banding machine with this utility model, multiple parallel material strips are pre-loaded, and one of the material strips is transported to the position of the main material strip conveyor 5 by the material strip conveyor 2. The material strip is sent from the position of the material strip conveyor 2 to the position of the main material strip conveyor 5 via the material strip guide plate assembly 4, and then the material strip currently sent to the position of the main material strip conveyor 5 is sent out by the main material strip conveyor 5, thus completing the material strip feeding; when one of the material strips is used up and needs to be replaced with a new material strip, it is only necessary to use the material strip conveyor 2 to cut the material strip. The conveyor belt 2 transports another conveyor belt from each of the various conveyor belts to the main conveyor belt 5. The main conveyor belt 5 then sends out the conveyor belt currently in use, thus quickly replacing the used conveyor belt and enabling continuous production. When switching to a conveyor belt of a different material and / or color is required, the current conveyor belt is first cut by the conveyor belt cutting device 6. Then, the conveyor belt slitting device 2 retrieves the conveyor belt of the current material and / or color from the main conveyor belt 5. Finally, the conveyor belt slitting device 2 transports the conveyor belt of the desired material and / or color to the main conveyor belt 5. The conveyor belt is transported to the main conveyor belt 5, and the main conveyor belt 5 then delivers the conveyor belt currently at the main conveyor belt 5, thus enabling rapid switching between conveyor belts of different materials and / or colors. Compared to existing single-channel conveyor belt devices for edge banding machines, this invention not only allows for rapid replacement of used conveyor belts for continuous production, greatly improving belt replacement efficiency and overall production efficiency, but also allows for simultaneous loading of conveyor belts of multiple materials and / or colors, enabling rapid switching to provide conveyor belts of different materials and / or colors according to different edge banding requirements of the board.

[0025] The material conveying device 2 includes several dual-channel material conveying devices 3. Each dual-channel material conveying device 3 includes a material conveying base 31 mounted on the feeding workbench 1, a material conveying drive wheel 32 rotatably connected to the material conveying base 31 in a vertical direction, a servo power mechanism 33 for driving the material conveying drive wheel 32 to rotate, two material conveying driven wheels 34 slidably connected to both sides of the material conveying drive wheel 32, and two driven wheel sliding power mechanisms 35 for driving the two material conveying driven wheels 34 to slide. The servo power mechanism 33 is mounted on the material conveying base 31, and its output end drives and connects to the material conveying drive wheel 32. Compared to using two independent conveying devices to convey two material belts separately to achieve dual-channel material conveying switching, the dual-channel material conveying device 3 of this invention drives the material conveying drive wheel 32 through the servo power mechanism 33. 2. When the driven wheel 34 of the conveyor belt slides close to the driving wheel 32 of the conveyor belt and clamps the conveyor belt between the driven wheel 34 and the driving wheel 32, the conveyor belt clamped between the driven wheel 34 and the driving wheel 32 is conveyed. When the driven wheel 34 slides away from the driving wheel 32 and the conveyor belt is not clamped between the driving wheel 32 and the driven wheel 34, the unclamped conveyor belt will not be conveyed. The two driven wheel sliding power mechanisms 35 control the two driven wheels 34 to slide close to or away from the driving wheel 32, thereby realizing dual-channel conveyor belt switching. The dual-channel conveyor belt device 3 of this utility model only needs one servo motor to realize dual-channel conveyor belt switching, which not only reduces the overall cost, but also makes the overall structure more compact and reasonable, and can be better applied to various application occasions.

[0026] The dual-channel belt conveyor 3 also includes two belt anti-reverse components 36 to prevent belt backflow. When the belt is not clamped during conveying, it may backflow or deviate due to various factors. The belt anti-reverse components 36 prevent the belt from backflowing, thereby achieving better belt conveying. The two belt anti-reverse components 36 each include an anti-reverse post 361 disposed behind the belt conveyor drive wheel 32, an anti-reverse wheel 362 slidably connected to one side of the anti-reverse post 361, and a drive wheel 362 for driving the anti-reverse movement. The anti-reverse power mechanism 363 drives the anti-reverse wheel 362 to slide closer to or further away from the anti-reverse post 361. When the anti-reverse wheel 362 slides closer to the anti-reverse post 361 and clamps the material belt between the anti-reverse wheel 362 and the anti-reverse post 361, the material belt will not retract or deviate. When the anti-reverse wheel 362 slides further away from the anti-reverse post 361 and the material belt is not clamped between the anti-reverse wheel 362 and the anti-reverse post 361, the material belt will not be restrained, thereby enabling the material belt to be conveyed.

[0027] The driven wheel sliding power mechanism 35 and the anti-reverse power mechanism 363 are of the same structure, making the overall structure more compact and reasonable. The driven wheel sliding power mechanism 35 includes a swing shaft 351 rotatably connected to the material conveyor base 31 in the vertical direction, a swing block 352 disposed on the swing shaft 351, a driven wheel shaft 353 disposed at one end of the swing block 352, an anti-reverse shaft 354 disposed at the other end of the swing block 352, and a push-pull cylinder 355. The push-pull cylinder 355 is disposed on the material conveyor base 31, and the output of the push-pull cylinder 355 is... The end-drive connected swing block 352 has a driven belt conveyor driven wheel 34 mounted on the driven wheel shaft 353, and a stop wheel 362 mounted on the stop shaft 354. When the push-pull cylinder 355 drives the swing block 352 to swing forward, the driven belt conveyor driven wheel 34 moves closer to the driven belt conveyor driven wheel 32, and the stop wheel 362 moves away from the stop post 361. When the push-pull cylinder 355 drives the swing block 352 to swing backward, the driven belt conveyor driven wheel 34 moves away from the driven belt conveyor driven wheel 32, and the stop wheel 362 moves closer to the stop post 361. Directional movement; the driven wheel sliding power mechanism 35 of this utility model can simultaneously drive the driven wheel 34 of the belt conveyor to move closer to the driving wheel 32 of the belt conveyor and clamp the belt between the driven wheel 34 and the driving wheel 32 of the belt conveyor, while also causing the anti-reverse wheel 362 to move away from the anti-reverse post 361 and loosen the belt between the anti-reverse wheel 362 and the anti-reverse post 361. It can also simultaneously drive the driven wheel 34 of the belt conveyor to move away from the driving wheel 32 of the belt conveyor and loosen the belt between the driven wheel 34 and the driving wheel 32 of the belt conveyor. When the anti-reverse wheel 362 moves closer to the anti-reverse post 361 and clamps the material belt between the anti-reverse wheel 362 and the anti-reverse post 361, it can prevent the material belt from being clamped by the driven wheel 34 and the driving wheel 32 of the material belt conveyor at the same time, and the material belt from being clamped by the anti-reverse wheel 362 and the anti-reverse post 361 at the same time. It can also prevent the material belt from being loose between the driven wheel 34 and the driving wheel 32 of the material belt conveyor at the same time, and the material belt from being loose between the anti-reverse wheel 362 and the anti-reverse post 361. Therefore, it can better ensure that the material belt is either clamped for conveying or clamped to prevent backflow.

[0028] The material conveyor belt 2 also includes a material belt limiting component 37, which includes a material belt limiting frame 371 and multiple material belt limiting blocks 372 disposed on the material belt limiting frame 371. The bottom of the material belt limiting block 372 has a U-shaped structure and the opening faces downward. By limiting the top and both sides of the material belt with the material belt limiting blocks 372, it can effectively prevent the material belt from running off-center during the conveying process, thereby better ensuring the continuous and stable conveying of the material belt.

[0029] The height of the material belt limit block 372 on the material belt limit frame 371 is adjustable, and can be adjusted according to the actual height of the material belt, so as to be applicable to the limit of material belts of different heights, making it more flexible and practical.

[0030] The main conveyor belt device 5 includes a main conveyor drive wheel 51 rotatably connected to the conveyor belt worktable 1 in a vertical direction, a main conveyor rotational power mechanism 52 for driving the main conveyor drive wheel 51 to rotate, a main conveyor driven wheel 53 slidably connected to one side of the main conveyor drive wheel 51, and a main conveyor sliding power mechanism 54 for driving the main conveyor driven wheel 53 to slide. The main conveyor rotational power mechanism 52 is disposed on the conveyor belt worktable 1, and its output end is connected to the main conveyor drive wheel 51. The main conveyor sliding power mechanism 54 is disposed on the conveyor belt worktable 1, and its output end is connected to the main conveyor driven wheel 53. The main conveyor sliding power mechanism 54 drives the main conveyor driven wheel 53 to slide close to the main conveyor drive wheel 51 and clamp the conveyor belt between the main conveyor drive wheel 51 and the main conveyor driven wheel 53. The main conveyor rotational power mechanism 52 drives the main conveyor drive wheel 51 to rotate and convey the conveyor belt clamped between the main conveyor drive wheel 51 and the main conveyor driven wheel 53.

[0031] The strip cutting device 6 includes a strip cutting frame 61 mounted on the strip feeding table 1, a cutting block 62 slidably connected to the strip cutting frame 61 in the horizontal direction, and a cutting power mechanism 63 for driving the cutting block 62 to slide. The cutting power mechanism 63 is mounted on the strip cutting frame 61, and the output end of the cutting power mechanism 63 drives the cutting block 62. The strip cutting frame 61 is provided with a shearing part that cooperates with the cutting block 62. When it is necessary to cut the strip, the cutting power mechanism 63 drives the cutting block 62 to slide and form a shearing structure with the shearing part of the strip cutting frame 61, thereby enabling the strip to be cut quickly and conveniently.

[0032] This utility model also includes a belt pressing device 7 for pressing the top of the belt downwards; by pressing the belt pressing device 7 downwards at the end of the belt away from the main belt conveyor 5, this utility model can prevent the belt from tilting or shifting when it is delivered, thereby enabling better belt feeding.

[0033] The belt pressing device 7 includes a belt pressing block 71 that is slidably connected to the belt feeding worktable 1 in a vertical direction, and a belt pressing lifting power mechanism 72 for driving the belt pressing block 71 to slide. The belt pressing lifting power mechanism 72 is set on the belt feeding worktable 1, and the output end of the belt pressing lifting power mechanism 72 drives the belt pressing block 71. By driving the belt pressing block 71 to rise and fall through the belt pressing lifting power mechanism 72, it can adapt to the abutment limit of belts of different heights, making it more flexible and practical.

[0034] Working principle:

[0035] Multiple parallel material belts are preloaded. One of the material belts is transported to the position of the main material belt conveyor 5 by the material belt conveyor 2. The material belt is sent from the position of the material belt conveyor 2 to the position of the main material belt conveyor 5, passes through the material belt guide plate assembly 4, and then is sent out by the main material belt conveyor 5, thus completing the material belt feeding.

[0036] When one of the material belts runs out and needs to be replaced with a new one, the other material belt in the various material belts is simply transported to the position of the main material belt conveyor 5 through the material belt conveyor 2, and then the material belt currently delivered to the position of the main material belt conveyor 5 is sent out through the main material belt conveyor 5. This can quickly replace the used material belt and continue production.

[0037] When it is necessary to switch to different materials and / or colors of material strips, the current material strip is first cut by the material strip cutting device 6, and then the material strip of the current material and / or color is retrieved from the position of the main material strip conveyor 5 by the material strip conveyor 2. Then, the material strip of the required material and / or color is conveyed to the position of the main material strip conveyor 5 by the material strip conveyor 2, and the material strip currently delivered to the position of the main material strip conveyor 5 is sent out by the main material strip conveyor 5. This can achieve the rapid switching of material strips of different materials and / or colors.

[0038] Compared to existing single-channel tape feeding devices for edge banding machines, this invention can not only quickly replace used tape for continuous production, greatly improving tape changing efficiency and overall production efficiency, but also can be used to load tapes of multiple materials and / or colors simultaneously, and can quickly switch to provide tapes of different materials and / or colors according to different edge banding requirements of the board.

[0039] Of course, the above description is only a preferred embodiment of the present utility model.
