Description

Technical Field

[0001] The invention is used in the technical field of gluing of custom-made panel furniture, and particularly relates to a gluing method for panel furniture. Background Art

[0002] Customized panel furniture is mainly composed of artificial boards with different structures and different finishing materials compounded by special auxiliary materials. After the artificial boards are sawed into different specifications according to the size required by the customer, they are sealed on all sides with edge banding tape. The above-mentioned products that need edge banding are mainly sealed with EVA composite glue or PUR glue. At present, in order to save and reduce costs, artificial board manufacturers are using artificial board panels to improve the internal bonding strength, density, water absorption thickness expansion rate, static bending strength and other performance of the board. The worse the performance, the more likely it is to cause serious corner chipping of the artificial board. Therefore, in order to ensure the performance of panel furniture, PUR glue with better adhesion and waterproof properties is currently used to seal the edges of panel furniture. However, due to the high cost of PUR glue, in order to control costs, it is necessary to reduce the amount of glue applied to panel furniture in the gluing process. The reduction in the amount of glue applied can easily lead to quality problems such as debonding of the panel furniture edges. Panel furniture after edge banding is prone to problems such as end swelling and appearance defects. Summary of the Invention

[0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a method for gluing panel furniture, which can control the amount of glue applied while reducing the amount of glue applied.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A method for gluing panel furniture, comprising the following steps:

[0006] Step 1: The edge banding machine is equipped with a glue coating roller and a glue outlet. The edge banding machine performs edge banding along the side of the plate. The plate is divided into the head, middle and tail along the feeding direction. When the head area of ​​the plate reaches the predetermined position in the edge banding machine, the glue outlet discharges glue, and the glue coating roller applies glue to the head of the plate;

[0007] Step 2: When the glue coating roller passes through the middle area of ​​the plate, the glue output from the glue outlet is reduced, and the glue coating roller coats the middle area of ​​the plate with glue;

[0008] Step three: When the glue coating roller passes through the tail area of ​​the plate, the glue output from the glue outlet is increased, and the glue coating roller coats the tail of the plate with glue.

[0009] Preferably, the method includes step 4: rotating the plate, applying glue to other sides of the plate by the glue coating roller, and repeating the above steps 1 to 3.

[0010] Preferably, the edge banding machine is provided with a glue door for controlling the size of the glue outlet. The larger the glue outlet, the greater the glue output. The edge banding machine is provided with a control device for driving the glue door to move.

[0011] Preferably, the control device includes a connecting component and a cylinder, the connecting component is connected to the cylinder and the glue door, and the cylinder controls the glue door to move along the feeding direction through the connecting component.

[0012] Preferably, the cylinder is a multi-stroke cylinder, and the edge banding machine is provided with a scale for measuring the stroke of the cylinder.

[0013] Preferably, the edge banding machine is provided with a monitoring device for detecting the real-time position of the panel, the monitoring device is connected to the control device, and the control device moves the glue door according to the real-time position of the panel obtained by the monitoring device to control the size of the glue outlet.

[0014] Preferably, when the glue door is fully opened, the glue output is equal to the glue amount applied to the head and tail of the panel.

[0015] Preferably, the edge banding machine is provided with a feed port for inputting the panels and a conveyor belt for transporting the panels.

[0016] Preferably, the amount of glue applied to the head and tail of the plate is greater than the amount of glue applied to the middle of the plate, and the difference in the amount of glue applied to the head and tail of the plate and the amount of glue applied to the middle of the plate is 40 to 80 g / m 2 When using EVA composite glue, the glue coating amount in the middle of the panel is 220-250g / m 2 When using PUR glue, the glue amount in the middle of the panel is 140-170g / m 2 .

[0017] Preferably, the length of the head of the plate along the feeding direction is not less than 100 mm, and the length of the tail of the plate along the feeding direction is not less than 100 mm.

[0018] One of the above technical solutions has at least one of the following advantages or beneficial effects: the panel furniture gluing method applies glue to the side of the panel through a glue roller, and then the edge banding machine combines the edge banding tape with the panel to achieve edge banding. The panel moves at a uniform speed along the feed direction. The greater the glue output, the greater the amount of glue on the panel. The amount of glue on the panel can be controlled by controlling the amount of glue output. The panel furniture gluing method applies different amounts of glue to the head, middle and tail of the panel. Through the segmented quantitative glue control, the panel is quantitatively positioned and glued on demand, so that the end, head and tail of the panel have a large amount of glue, that is, the amount of glue applied to the parts of the panel that are prone to swelling is increased, and the amount of glue applied to the middle is small, so as to reduce the overall glue consumption of the panel, thereby reducing the glue consumption while ensuring the edge banding quality of the panel, saving costs, improving the quality of edge banding products, and avoiding appearance defects of the panel.

[0027] in, Figure 2 The reference direction coordinate system of the embodiment of the present invention is given below. Figure 2 The embodiment of the present invention is described in the direction shown. Figure 2 The direction shown in is the feeding direction.

[0028] An embodiment of the present invention provides a method for gluing panel furniture, comprising the following steps:

[0029] Step 1: The edge banding machine is equipped with a glue coating roller 1 and a glue outlet 2. The edge banding machine performs edge banding along the side of the plate. The plate is divided into a head 3, a middle part 4 and a tail 5 along the feeding direction. When the head 3 area of ​​the plate reaches the predetermined position in the edge banding machine, the glue outlet 2 discharges glue, and the glue coating roller 1 coats the head 3 of the plate with glue, completing the gluing of the end and head 3 of the plate;

[0030] Step 2: When the glue coating roller 1 passes through the middle area 4 of the plate, the glue output from the glue outlet 2 is reduced, and the glue coating roller 1 applies glue to the middle area 4 of the plate;

[0031] Step three: When the glue coating roller 1 passes through the tail 5 area of ​​the plate, the glue output of the glue outlet 2 is increased, and the glue coating roller 1 applies glue to the tail 5 of the plate. After completing the gluing of the tail 5 area of ​​the plate, the glue outlet 2 stops discharging glue, completing the edge sealing of this side of the plate.

[0032] The glue roller 1 applies glue to the side of the panel, and then the edge banding machine combines the edge banding tape with the panel to achieve edge banding. The panel moves at a uniform speed along the feed direction. The greater the glue output, the greater the amount of glue on the panel. The amount of glue on the panel can be controlled by controlling the amount of glue output. The panel furniture gluing method applies different glue amounts to the head 3, middle 4 and tail 5 of the panel. Through the segmented quantitative glue control, the panel is quantitatively positioned and applied with glue on demand, so that the end, head 3 and tail 5 of the panel have a large amount of glue, that is, the amount of glue applied to the parts of the panel that are prone to swelling is increased, and the amount of glue applied to the middle 4 is small, so as to reduce the overall glue consumption of the panel, thereby reducing the glue consumption while ensuring the edge banding quality of the panel, saving costs, improving the quality of edge banding products, and avoiding appearance defects of the panel.

[0033] As a preferred embodiment of the present invention, the method for gluing panel furniture also includes step four: rotating the panel, applying glue to the other side edges of the panel with the gluing roller 1, and repeating the above steps one to three to achieve edge sealing of each side edge of the panel.

[0034] Preferably, the edge banding machine is provided with a glue door 6 for controlling the size of the glue outlet 2. The larger the glue outlet 2 is, the greater the glue output is. The edge banding machine is provided with a control device for driving the glue door 6 to move.

[0035] Preferably, a glue pot for holding glue is provided in the edge banding machine, and the glue pot is connected to the glue door 6. When glue is added into the glue pot, the glue can flow out through the glue outlet 2, and the amount of glue discharged is controlled by the degree of opening of the glue door 6.

[0036] In some embodiments, the control device includes a connecting component 7 and a cylinder 8, the connecting component 7 is connected to the cylinder 8 and the glue gate 6, and the cylinder 8 controls the glue gate 6 to move along the feeding direction through the connecting component 7. Preferably, in step two, the cylinder 8 works to reduce the glue outlet 2 by controlling the glue gate 6, and the amount of glue applied is reduced. In step three, the cylinder 8 works to increase the glue outlet 2 through the glue gate 6, and the amount of glue applied is increased.

[0037] In some embodiments, the cylinder 8 is a multi-stroke cylinder. Preferably, the edge banding machine is provided with a scale for measuring the stroke of the cylinder 8. By controlling the stroke of the cylinder 8, the glue door 6 can be controlled to achieve precise control of the amount of glue output.

[0038] As a preferred embodiment of the present invention, a monitoring device for detecting the real-time position of the panel is provided on the edge banding machine. The monitoring device is connected to the control device. The control device moves the glue door 6 according to the real-time position of the panel obtained by the monitoring device to control the size of the glue outlet 2. It can be understood that the monitoring device includes a video monitoring device or an infrared sensing device, etc. After it monitors the panel, it provides the real-time position of the panel to the glue coating machine through the previously set formula for calculating the position of the panel, so as to realize the monitoring of the real-time position of the panel. During operation, if the monitoring device detects that the panel enters the edge banding machine, the edge banding machine works normally and performs step one to step three gluing work on the panel. If the monitoring device does not detect that the panel enters the edge banding machine, the edge banding machine stops working and issues an alarm.

[0039] In some embodiments, when the glue door 6 is fully open, the amount of glue discharged is equal to the amount of glue applied to the head 3 and tail 5 of the panel. When the glue roller 1 is edge-sealing the panel, wood chips on the panel are easily stuck to the glue roller 1. In step four, since the glue door 6 is in a fully open state, the wood chips can be removed from the glue roller while a large amount of glue is discharged, thereby completing the automatic cleaning requirement of the glue roller 1.

[0040] Preferably, the edge banding machine is provided with a feed port for inputting the panels and a conveyor belt for transporting the panels, so that the edge banding machine can perform edge banding on the panels along the feeding direction.

[0041] The glue amount of the head 3 and tail 5 of the plate is greater than the glue amount of the middle 4 of the plate. The difference between the glue amount of the head 3 and tail 5 of the plate and the glue amount of the middle 4 of the plate is 40 to 80 g / m 2 When using EVA composite glue, the glue coating amount of the middle part 4 of the panel is 220~250g / m 2 When using PUR glue, the glue amount of the middle part 4 of the panel is 140-170g / m 2 , ensuring the edge banding quality of the panels.

[0042] Preferably, the length of the head 3 of the plate along the feeding direction is not less than 100 mm, and the length of the tail 5 of the plate along the feeding direction is not less than 100 mm, to ensure the edge sealing quality of the head 3 and tail 5 of the plate.
