Description

Technical Field

[0001] This utility model relates to the field of decorative panel production technology, specifically to the adhesive filament adsorption mechanism of an edge banding machine for decorative panel production. Background Technology

[0002] During the processing of decorative panels, the cutting and shaping of the panels exposes the cross-section of the core material. These edges are prone to moisture absorption, damage, or cracking during use, thus affecting aesthetics and lifespan. Therefore, edge sealing is necessary for decorative panels. Using edge sealing strips or materials to cover and bond the edges not only seals pores, prevents moisture, and prevents edge peeling, but also improves appearance consistency, enabling the decorative panels to meet both durability and decorative standards.

[0003] Edge banding is a high-frequency, repetitive process that requires high precision and bonding quality. Manual operation is inefficient and inconsistent. Edge banding machines can automatically feed, heat and seal the edge banding strip, press it tightly, and cut it to finish the process. This ensures that the edge banding strip fits tightly to the board edge, is accurately positioned, and operates at a stable speed. As a result, it significantly increases production capacity, reduces labor costs, and guarantees the consistency of the finished product's appearance and joint strength. It is a key piece of equipment on modern decorative panel production lines.

[0004] Currently, during the edge banding process, especially under high pressure or high temperature conditions, adhesive may be squeezed out along the gaps, resulting in excess adhesive that adheres to the upper and lower surfaces of the decorative panel or the transmission components of the machine tool, causing contamination and potential malfunctions. Therefore, an adhesive removal step is often added to the edge banding process to remove the excess adhesive.

[0005] However, the current adhesive removal process still has some shortcomings during operation, as follows: Due to thickness variations in the decorative panel, the edge banding strip may occasionally protrude above the panel surface. Additionally, after the adhesive on the panel edges is scraped off, adhesive threads form and move along the panel surface. As the number of adhesive threads increases, a large amount accumulates around the adhesive removal blade during the adhesive removal process. Sometimes, the blade tip of the adhesive removal blade will remove adhesive threads along with the adhesive, which not only affects the adhesive removal efficiency of the blade but also easily leads to the adhesive threads re-adhering to the edge of the panel surface or leaving indentations on the panel surface.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] The purpose of this invention is to provide a glue filament adsorption mechanism for an edge banding machine used in decorative panel production.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The edge banding machine used in decorative panel production includes a glue filament adsorption mechanism. The edge banding machine comprises a frame with a conveyor line for horizontally transferring decorative panels. The conveyor line has glue removal stations and adsorption stations arranged sequentially along the transfer direction on both sides. The glue filament adsorption mechanism is located at the adsorption station to remove glue filaments remaining on the decorative panel after the glue removal station. The adsorption mechanism includes an adsorption unit, which comprises multiple adsorption cylinders for sucking up the glue filaments removed at the glue removal station and a corresponding auger structure within each adsorption cylinder. All the adsorption cylinders are arranged along the conveyor line's transport direction. Located beside the conveyor line, all the adsorption cylinders are arranged in pairs, with the suction ports of each pair of adsorption cylinders facing each other and spaced apart, for jointly adsorbing and treating two opposite surfaces of the same decorative panel. The spacing between the suction ports of each pair of adsorption cylinders is greater than or equal to the thickness of the decorative panel. When the conveyor line horizontally moves the decorative panel to the adsorption station, the suction ports of each pair of adsorption cylinders approach the edges of the two opposite surfaces of the decorative panel. One end of the auger structure is positioned and connected to the side of the conveyor line as the drive end, and the other end is suspended inside the adsorption cylinder. The auger structure is configured to spirally introduce the adhesive filament into the adsorption cylinder when rotating.

[0009] In the above scheme, the adhesive filaments can be quickly removed by using multiple adsorption cylinders in the adsorption unit and the auger structure corresponding to the adsorption cylinders. Specifically, the decorative panel is moved horizontally by the conveyor line so that the decorative panel passes through the adhesive removal station and the adsorption station in sequence. Since the adhesive filaments scraped off at the adhesive removal station will slide along the surface of the decorative panel to the adsorption station, the adsorption cylinder will suck the adhesive filaments into the adsorption cylinder. At the same time, the auger structure will work to introduce the adhesive filaments accumulated at the adsorption port into the adsorption cylinder.

[0010] In summary, the paired suction cylinders in this application are equivalent to two vacuum cleaners, one above the other, aimed at the edge of the decorative panel to perform suction. At the same time, each vacuum cleaner has a auger structure that can send loose adhesive threads into the suction cylinder, avoiding the accumulation of adhesive threads at the suction port.

[0011] A further technical solution is that the adsorption cylinder includes a cylinder body, the cylinder body is located at the adsorption station, and one end of the cylinder body facing the decorative panel located at the adsorption station is a suction port. The inner side wall of the suction port is provided with a suction groove, which is arranged along the conveyor line transfer direction and facing the adhesive removal station.

[0012] With the above design, the suction range of the suction port is increased by using a suction groove, thereby better drawing the filaments into the adsorption cylinder.

[0013] In a further technical solution, the adhesive filament adsorption mechanism also includes multiple outlet structures, each of which is respectively configured to correspond one-to-one with each adsorption unit; the outlet structure includes a negative pressure collecting pipe, a first branch pipe and a second branch pipe; the first branch pipe and the second branch pipe are respectively connected to the end of each pair of adsorption cylinders in each adsorption unit, and the negative pressure collecting pipe is connected to the first branch pipe and the second branch pipe, so as to simultaneously send out the adhesive filaments in the corresponding two adsorption cylinders through the suction of the negative pressure collecting pipe.

[0014] With the above design, the two adsorption cylinders in each adsorption unit can send the filaments to the collection device through the corresponding outlet structure.

[0015] In a further technical solution, the diameter of the auger structure is smaller than the inner diameter of the adsorption cylinder, and the axis of each auger structure coincides with the axis of the corresponding adsorption cylinder.

[0016] The above design ensures that the auger structure does not affect the suction operation of the adsorption cylinder. At the same time, the axis of the auger structure coincides with the axis of the corresponding adsorption cylinder, which can better drive the adhesive filament into the adsorption cylinder and prevent the adhesive filament from accumulating in a certain part. This is because if the axis of the auger structure is tilted, there will be a very close part between the inner wall of the adsorption cylinder and the auger structure. After the adhesive filament enters the adsorption cylinder, it is easy to get stuck between the auger structure and the inner wall of the adsorption cylinder.

[0017] In a further technical solution, the auger structure includes a fixed shaft disposed inside the adsorption cylinder, and an auger body is provided on the side wall of the fixed shaft. One end of the fixed shaft serves as the driving end of the auger structure and is positioned and connected to a driver fixedly disposed on the conveyor line. The end of the auger body away from the driver is close to the suction port of the adsorption cylinder and is located in the suction groove.

[0018] With the above design, the fixed shaft can rotate the auger body, and the rotating auger body can quickly send the sucked-in glue filaments into the adsorption cylinder through the suction groove, so that the glue filaments will not be wrapped around the decorative panel or other parts.

[0019] In a further technical solution, the end of the fixed shaft away from the driver extends beyond the end of the auger body, and a cleaning blade is fixedly sleeved on the end of the fixed shaft away from the driver.

[0020] The above design allows for better delivery of the adhesive filaments into the adsorption cylinder.

[0021] In a further technical solution, the length of the auger body is less than the length of the adsorption cylinder and the fixed shaft, that is, the end of the auger body away from the cleaning blade does not exceed the connection point between the first branch pipe or the second branch pipe and the adsorption cylinder.

[0022] The above design prevents the rubber strands from being blocked by the auger body and thus unable to enter the negative pressure manifold.

[0023] A further technical solution involves spacing the suction ports of each pair of adsorption cylinders at 1 to 2 times the thickness of the decorative panel to ensure sufficient suction and guarantee that the adhesive strands generated during the adhesive removal process can be stably, reliably, and quickly adsorbed by the adsorption cylinders.

[0029] The working principle and advantages of this utility model are as follows: In this application, the adhesive filaments can be quickly removed by using multiple adsorption cylinders in the adsorption unit and an auger structure corresponding to the adsorption cylinders. Specifically, the decorative panel is moved horizontally by the conveyor line so that the decorative panel passes through the adhesive removal station and the adsorption station in sequence.

[0035] See appendix Figure 1 - Figure 7As shown, the edge banding machine for decorative panel production has a glue filament adsorption mechanism. The edge banding machine includes a frame 1, on which a conveyor line 2 for horizontally transferring decorative panels is provided. The conveyor line 2 has a glue removal station 22 and an adsorption station 21 arranged sequentially along the transfer direction. The glue filament adsorption mechanism 5 is located at the adsorption station 21 to remove the glue filaments remaining on the decorative panel after being processed at the glue removal station 22. The glue filament adsorption mechanism 5 includes an adsorption unit 3, which includes multiple adsorption cylinders 31 for sucking up the glue filaments removed at the glue removal station 22 and a auger structure 32 correspondingly arranged in each adsorption cylinder 31. All the adsorption cylinders 31 are arranged along the conveying direction of the conveyor line 2 on the side of the conveyor line 2, and all the adsorption cylinders 31 are arranged in pairs. The suction ports 312 of each pair of adsorption cylinders 31 are opposite and spaced apart. The two opposite surfaces of the same decorative panel are treated by joint suction, and the interval between the suction ports 312 of each pair of suction cylinders 31 is greater than or equal to the thickness of the decorative panel. When the conveyor line 2 horizontally moves the decorative panel to the suction station 21, the suction ports 312 of each pair of suction cylinders 31 are close to the edges of the two opposite surfaces of the decorative panel. The interval between the suction ports of each pair of suction cylinders is 1 to 2 times the thickness of the decorative panel (it can be 1, 1.2, 1.3, 1.5 or 2 times, preferably 1.2 times), so as to ensure sufficient suction and ensure that the glue filaments generated by the glue removal operation can be stably, reliably and quickly adsorbed by the suction cylinders. One end of the auger structure 32 is positioned and connected to the side of the conveyor line 2 as the driving end, and the other end is suspended in the suction cylinder 31. The auger structure 32 is configured to spirally introduce the glue filaments into the suction cylinder 31 when rotating.

[0036] In this application, the auger structure 32 can be a rigid auger made of metal or a flexible auger made of rubber or plastic, as is available in the prior art. Here, a rigid auger can be selected.

[0037] In this application, the interval between the suction ports 312 of each pair of suction cylinders 31 should be greater than or equal to the thickness of the decorative panel, preferably slightly greater than the thickness of the decorative panel, but not too large, to ensure that the suction ports 312 and the surface of the decorative panel form an appropriate gap fit.

[0038] In this application, the adhesive filaments can be quickly removed by using multiple adsorption cylinders 31 in the adsorption unit 3 and the auger structure 32 corresponding to the adsorption cylinders 31. Specifically, the decorative panel is moved horizontally by the conveyor line 2 so that the decorative panel passes through the adhesive removal station 22 and the adsorption station 21 in sequence. Since the adhesive filaments scraped off by the adhesive removal station 22 will slide along the surface of the decorative panel to the adsorption station 21, the adsorption cylinder 31 will suck the adhesive filaments into the adsorption cylinder 31 when it is working. At the same time, the auger structure 32 will work to introduce the adhesive filaments accumulated at the adsorption port into the adsorption cylinder 31.

[0039] In summary, the paired suction cylinders 31 in this application are equivalent to two vacuum cleaners, one above the other, aimed at the edge of the decorative panel to perform suction operation. At the same time, each vacuum cleaner has a auger structure 32, which can send loose adhesive threads into the suction cylinder 31, avoiding the phenomenon of adhesive threads accumulating at the suction port 312.

[0040] Preferably, the adsorption cylinder 31 includes a cylinder body 311, which is located at the adsorption station 21. One end of the cylinder body 311 facing the decorative panel located at the adsorption station 21 is a suction port 312. The inner side wall of the suction port 312 is provided with a suction groove 313, which is arranged along the transfer direction of the conveyor line 2 and facing the adhesive removal station 22.

[0041] With the above design, the suction range of the suction port 312 is increased by the suction groove 313, so as to better draw the filament into the adsorption cylinder 31.

[0042] Preferably, the adhesive filament adsorption mechanism 5 further includes multiple outlet structures 4, each outlet structure 4 being configured in a one-to-one correspondence with each adsorption unit 3; each outlet structure 4 includes a negative pressure collecting pipe 41, a first branch pipe 42, and a second branch pipe 43; the first branch pipe 42 and the second branch pipe 43 are respectively connected to the ends of each pair of adsorption cylinders 31 in each adsorption unit 3, and the negative pressure collecting pipe 41 is connected to the first branch pipe 42 and the second branch pipe 43, so as to simultaneously deliver the adhesive filaments in the corresponding two adsorption cylinders 31 through the suction of the negative pressure collecting pipe 41.

[0043] With the above design, the two adsorption cylinders 31 in each adsorption unit 3 can send the adhesive filaments to the collection device through the corresponding outlet structure 4.

[0044] Specifically, connect the negative pressure manifold 41 to the external negative pressure suction device, and then start the external negative pressure suction device. At this time, the negative pressure manifold 41 starts to suction, so that the first branch pipe 42 and the second branch pipe 43 respectively suck the glue strands in the corresponding two adsorption cylinders 31. After the glue strands are sucked out, the glue strands will be sent out along the negative pressure manifold 41.

[0045] Preferably, the diameter of the auger structure 32 is smaller than the inner diameter of the adsorption cylinder 31, and the axis of each auger structure 32 coincides with the axis of the corresponding adsorption cylinder 31.

[0046] With the above design, the auger structure 32 will not affect the suction operation of the adsorption cylinder 31. At the same time, the axis of the auger structure 32 coincides with the axis of the corresponding adsorption cylinder 31, which can better drive the glue filament into the adsorption cylinder 31 and prevent the glue filament from accumulating in a certain part. This is because once the axis of the auger structure 32 is tilted, there will be a very close part between the inner wall of the adsorption cylinder 31 and the auger structure 32. After the glue filament enters the adsorption cylinder 31, it is easy to get stuck between the auger structure 32 and the inner wall of the adsorption cylinder 31.

[0047] Preferably, the auger structure 32 includes a fixed shaft 321 disposed inside the adsorption cylinder 31. The side wall of the fixed shaft 321 is provided with an auger body 322. One end of the fixed shaft 321 serves as the driving end of the auger structure 32 and is positioned and connected to the driver 324 fixedly disposed on the conveyor line 2. The end of the auger body 322 away from the driver 324 is close to the suction port 312 of the adsorption cylinder 31 and is located in the suction groove 313.

[0048] The driver 324 can be equipped with a motor.

[0049] With the above design, the fixed shaft 321 can rotate the auger body 322, and the rotating auger body 322 can quickly send the sucked-in glue thread into the adsorption cylinder 31 through the suction groove 313, so that the glue thread will not be wrapped around the decorative panel or other parts.

[0050] Preferably, the end of the fixed shaft 321 away from the driver 324 extends beyond the end of the auger body 322, and a cleaning blade 323 is fixedly sleeved on the end of the fixed shaft 321 away from the driver 324.

[0051] The above design is used to better deliver the adhesive filaments into the adsorption cylinder 31.

[0052] Preferably, the length of the auger body 322 is less than the length of the adsorption cylinder 31 and the fixed shaft 321, that is, the end of the auger body 322 away from the cleaning blade 323 does not exceed the connection between the first branch pipe 42 or the second branch pipe 43 and the adsorption cylinder 31.

[0053] The above design ensures that the rubber strands are not blocked by the auger body 322 and thus cannot enter the negative pressure manifold 41.

[0054] Working principle: The decorative panel is moved horizontally by the conveyor line 2, passing sequentially through the adhesive removal station 22 and the adsorption station 21. At this time, the external negative pressure suction device is activated, and the negative pressure manifold 41 begins suction, causing the first branch pipe 42 and the second branch pipe 43 to respectively suction the two corresponding adsorption cylinders 31, thereby creating negative pressure at the suction port 312. The adhesive fibers scraped off at the adhesive removal station 22 are then introduced into the suction port 312 by the suction groove 313.

[0055] At the same time, the driver 324 works, rotating the fixed shaft 321 so that the auger body 322 and the cleaning blade 323 rotate around the axis of the fixed shaft 321. At this time, the cleaning blade 323 will break the glue strands wrapped around the decorative panel or other parts, while the auger body 322 will send the glue strands into the adsorption cylinder 31, and finally send them out along the negative pressure collection pipe 41.

[0056] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
