[0002] Boards are flat rectangular building material boards usually made into standard sizes, which can be used as components of walls, ceilings or floors. During the processing of the boards, glue is needed to seal the edges of the boards. Commonly used glues include EVA glue and PUR glue. EVA glue has a simple production process and is affordable. PUR glue is very stable, has good waterproof and moisture-proof properties, is not easy to debond, and is more suitable for use in the kitchen.

[0003] For example, a Chinese patent (publication number: CN211359387U) discloses a gluing device for a woodworking edge banding machine, which solves the problems of unreasonable structure of the glue roller in the existing gluing device, complex sealing, and sealing failure after long-term use; the application provides a gluing device with a simple structure, the gluing roller includes a rotating roller and a gluing sleeve, a gluing cavity is provided between the rotating roller and the gluing sleeve, a plurality of gluing through holes are opened on the gluing sleeve, and the glue in the gluing cavity is evenly adhered to the cross-section of the board through centrifugal force and the pressure of the glue supply system.

[0004] Since the use environment of the board is different, the material requirements for the glue will also be different. However, since the above device is only provided with a single glue supply box, it is not convenient to switch the glue application according to the specific use environment requirements of the board. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a switchable gluing device for an edge banding machine, which has the advantages of being able to replace glue as needed, etc., solving the problem that the prior device cannot meet the different glue requirements of the board according to different usage environments.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a switching gluing device for an edge banding machine, comprising a mounting plate, a pneumatic motor is fixedly mounted on the back of the right side of the top surface of the mounting plate, a pneumatic glue door is fixed to the output shaft of the pneumatic motor, a gluing mechanism is provided on the mounting plate, a support frame is fixed to the bottom surface of the mounting plate, an EVA glue feeding mechanism is provided on the mounting plate, and a PUR glue feeding mechanism is provided on the mounting plate.

The gluing mechanism also includes a laser sensing probe fixedly mounted on the back of the support frame and located directly behind the gluing shaft.

[0008] Furthermore, the EVA glue feeding mechanism includes a melt assembly and a control assembly arranged on the melt assembly.

[0009] Furthermore, the melt assembly includes a first EVA melt box fixedly mounted on the front left side of the top of the mounting plate, and the melt assembly also includes a second EVA melt box fixedly mounted on the back left side of the top of the mounting plate and fixed to the back side of the first EVA melt box.

[0011] Furthermore, the PUR glue feeding mechanism includes a PUR joint fixedly mounted on the left and right sides of the back of the top surface of the mounting plate, and a PUR valve fixedly mounted on the PUR joint.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects: the utility model is provided with an EVA glue feeding mechanism and a PUR glue feeding mechanism, and the PUR glue supply process is in a sealed state, so as to prevent the PUR glue from losing its effect due to being exposed to the air for too long. In addition, the EVA glue feeding mechanism and the PUR glue feeding mechanism can switch and apply two kinds of EVA glues and two kinds of PUR glues respectively, and the EVA glue feeding mechanism and the PUR glue feeding mechanism are two independent glue feeding mechanisms, so the switching and applying of four different glues can be realized according to processing needs, and the processing is more convenient and practical.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 In this embodiment, a switching glue coating device for an edge banding machine includes a mounting plate 4, a pneumatic motor 14 is fixedly mounted on the back of the right side of the top surface of the mounting plate 4, a pneumatic glue door 6 is fixed on the output shaft of the pneumatic motor 14, and the pneumatic motor 14 can control the opening and closing of the pneumatic glue door 6. A gluing mechanism is provided on the mounting plate 4, a supporting frame 15 is fixed on the bottom surface of the mounting plate 4, an EVA glue feeding mechanism is provided on the mounting plate 4, and a PUR glue feeding mechanism is provided on the mounting plate 4.

[0019] It should be noted that EVA glue is the most common hot melt adhesive on the market. Its production process is simple. EVA glue is bonded to the edge sealing by heating. It is relatively cheap, but because more glue is used, it is easy to debond and overflow. Therefore, the edge sealing with EVA glue will have obvious glue lines, and it is normal for the glue lines to turn black, which is especially unfriendly to light-colored or white boards. In addition, EVA glue edge sealing is easy to soften and fall off in a high temperature and high humidity environment, so it is not recommended to use in kitchens and bathrooms. PUR glue is a glue that is melted by heating and reacts with moisture in the air. PUR glue has very strong stability, good waterproof and moisture-proof properties, and is not easy to debond. It is more suitable for use in high temperature and high humidity environments such as kitchens and bathrooms. The PUR glue lines are not obvious and the overall appearance is more beautiful.

[0020] See also Figure 1 and Figure 2 The gluing mechanism includes a gluing shaft 5 fixedly mounted on the right side of the bottom of the mounting plate 4 and fixed to the pneumatic glue door 6, a power motor 7 fixedly mounted on the bottom of the outer surface of the gluing shaft 5, the power motor 7 can rotate the gluing shaft 5, and a gluing head 8 fixed at the bottom end of the gluing shaft 5. The gluing mechanism also includes a laser sensing probe 11 fixedly mounted on the back of the support frame 15 and located directly behind the gluing shaft 5. The laser sensing probe 11 can monitor the amount of glue inside the gluing shaft 5.

[0021] Among them, the EVA glue feeding mechanism includes a melt assembly and a control assembly arranged on the melt assembly. The melt assembly includes a first EVA melt box 1 fixedly mounted on the front left side of the top of the mounting plate 4. The melt assembly also includes a second EVA melt box 2 fixedly mounted on the back left side of the top of the mounting plate 4 and fixed to the back side of the first EVA melt box 1. The melt box is a device in the prior art, which can heat and melt the EVA glue particles. Two melt boxes can hold two different EVA glue particles, so that the glue coating can be replaced according to specific needs, which is more practical.

[0022] At the same time, the control component includes a pneumatic plunger 3 fixed at the bottom of the first EVA melt box 1 and the second EVA melt box 2 and fixed to the front and rear ends of the left side of the top surface of the mounting plate 4, a first EVA valve 9 fixedly installed on the left side of the front pneumatic plunger 3, and a second EVA valve 10 fixedly installed on the left side of the back pneumatic plunger 3. The two valves can control the glue discharge of the two melt boxes respectively, making it convenient to switch different EVA glues.

[0023] Finally, the PUR glue feeding mechanism includes a PUR connector 12 fixedly mounted on the left and right sides of the top back surface of the mounting plate 4, and a PUR valve 13 fixedly mounted on the PUR connector 12. The two PUR connectors 12 can be respectively connected to a PUR glue machine containing two types of PUR glues, wherein the PUR glue machine is a device in the prior art, and the glue machine can deliver PUR glue to the PUR connector 12.

[0024] The working principle of the above embodiment is:

[0025] When EVA glue is delivered, first, two kinds of EVA granular glue are poured into the first EVA melt box 1 and the second EVA melt box 2 respectively. When the corresponding melt box is selected, the first EVA melt box 1 and the second EVA melt box 2 start to heat and melt the corresponding EVA granular glue. When the temperature reaches the glue melting point, the corresponding first EVA valve 9 or the second EVA valve 10 on the pneumatic plunger 3 reciprocates to squeeze the corresponding melted EVA glue to the glue coating shaft 5 through the pneumatic plunger 3. At this time, the pneumatic glue door 6 is in an open state, and the glue coating shaft 5 is in a rotating state driven by the power motor 7. When the amount of glue squeezed onto the running glue coating shaft 5 reaches the amount detected by the laser sensing probe 11 on the side, the pneumatic plunger 3 stops reciprocating motion and stops squeezing, and so on.

[0026] When feeding PUR glue, firstly, two PUR joints 12 are connected to two PUR glue machines respectively. When the temperature of the pot body reaches the set temperature, the corresponding PUR valve 13 is opened, and the pneumatic glue door 6 at the glue coating is also opened. The melted PUR glue begins to flow to the rotating glue coating shaft 5 under the pressure of the PUR glue machine. When the laser sensor probe 11 detects that the glue on the rotating glue coating shaft 5 reaches a certain amount, the PUR glue machine stops gluing, and the corresponding PUR valve 13 is closed. This cycle repeats, and the PUR glue supply process is in a closed state.

[0027] Therefore, the utility model can apply specific glue according to different use environments of the board, and can realize one gluing mechanism to switch between two PUR glues and two EVA glues, and the PUR glue supply process is in a sealed state, ensuring that the PUR glue can be used for a long time.

[0028] It can be understood that the control method of the present invention is controlled by a controller, the control circuit of the controller can be implemented by simple programming by technicians in this field, the provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
