Description

Technical Field

[0001] The utility model relates to the technical field of plate edge banding equipment, in particular to a glue coating device and an edge banding machine. Background Art

[0002] One of the processes of the edge banding machine is to attach the edge banding tape to the side of the board. Before that, the edge banding surface of the board needs to be coated with glue to facilitate the attachment of the edge banding tape. Generally, the side of the board is abutted against the gluing shaft, and as the board moves linearly, the gluing shaft continues to rotate, and then the side of the board is glued.

[0003] Some existing gluing devices use the elastic force of the spring to push the entire mechanism where the gluing shaft is located toward the plate, so that the gluing shaft fits onto the edge-sealed surface of the plate. In the process of gluing a plate, initially, glue is attached to the surface of the gluing shaft, and there is a certain distance between the edge-sealed surface of the plate and the surface of the gluing shaft due to the presence of glue. As the plate is coated, the amount of glue at the corresponding position on the surface of the gluing shaft decreases. Under the force of the spring, the distance between the gluing shaft and the edge-sealed surface of the plate becomes smaller and smaller, and the plate blocks the glue replenishment at the corresponding position of the gluing shaft. This results in insufficient glue on the edge-sealed surface of the second half of the plate, affecting the subsequent edge-sealing process. Utility Model Content

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0041] According to some embodiments of the present invention, referring to Figures 1 to 4 ,and Fig. 9 The gluing device includes a frame 100, a translation assembly 200, a gluing assembly 300 and a magnetic lock assembly 400. An elastic member 110 is provided on the frame 100, and the elastic member 110 is a spring. The translation assembly 200 is slidably connected to the frame 100, and the translation assembly 200 can reciprocate in the front-to-back direction relative to the frame 100. The elastic member 110 is connected to the translation assembly 200, and the elastic member 110 applies a forward elastic force to the translation assembly 200. The gluing assembly 300 includes a gluing seat 310, a gluing shaft 320, a glue bin 330 and a driving component 340. The glue coating seat 310 is mounted on the translation assembly 200, the glue coating shaft 320 is rotatably connected to the glue coating seat 310, the axis direction of the glue coating shaft 320 is in the vertical direction, the glue tank 330 is used to add glue to the glue coating shaft 320, the driving component 340 can drive the glue coating shaft 320 to rotate, the driving component 340 is arranged below the glue coating shaft 320, and the glue tank 330 is mounted on the glue coating seat 310 and arranged above the glue coating shaft 320. The glue coating seat 310 is provided with a positioning block 350, the front side of the positioning block 350 is located in front of the glue coating shaft 320, and the positioning block 350 is used to abut against the plate 130 to position the plate 130. The magnetic lock assembly 400 is mounted on the frame 100, and the magnetic lock assembly 400 is attached to the translation assembly 200. When the magnetic lock assembly 400 is powered on, the magnetic lock assembly 400 absorbs the translation assembly 200 , and the translation assembly 200 cannot move in the front-back direction, so that the translation assembly 200 and the frame 100 are relatively fixed.

[0042] It is understandable that, referring to Figure 1 , Figure 2 and Fig. 9When the edge banding machine clamps the plate 130 and transports the plate 130 from left to right, the plate 130 contacts and abuts against the positioning block 350, and the plate 130 pushes the translation assembly 200 backward through the positioning block 350. Since the elastic member 110 applies a forward force to the translation assembly 200, the front side of the positioning block 350 can be stably attached to the plate 130, thereby ensuring that the gap between the outer circumference of the gluing shaft 320 and the plate 130 in the front-to-back direction remains unchanged, and the positioning between the gluing shaft 320 and the plate 130 is completed. The outer circumference of the gluing shaft 320 has a ring-shaped glue layer 360 of a certain thickness. In the process of the plate 130 moving from left to right, the side of the plate 130 contacts the glue layer 360 and glue is applied to the side of the plate 130. The driving component 340 drives the gluing shaft 320 to rotate so that the glue on the outer circumference of the gluing shaft 320 can be evenly applied to the side of the plate 130. At the same time, the glue in the glue tank 330 passes through the gap between the glue-applying shaft 320 and the plate 130 to replenish the glue to the outer peripheral surface of the glue-applying shaft 320, so as to prevent the thickness of the glue layer 360 from becoming smaller and causing uneven glue coating.

[0043] The gluing device can fully apply glue to the side of the plate 130 , thereby avoiding uneven glue on the side of the plate 130 and improving the edge sealing quality of the plate 130 .

[0044] It can also be understood that the gluing device uses a magnetic lock assembly 400 to lock the translation assembly 200 by magnetic attraction. The magnetic lock assembly 400 has a strong adsorption force on the translation assembly 200, and the locking is stable. Compared with the locking method achieved by tightening a cylinder or a motor, it is gentler and avoids crushing parts.

[0045] According to some embodiments of the present invention, referring to Figures 2 to 4 The translation assembly 200 includes a sliding seat 210 and a sliding rod 220. The sliding rod 220 is fixed on the sliding seat 210. The frame 100 is provided with a guide plate 140. The sliding rod 220 is passed through the guide plate 140 and can reciprocate along the front and rear directions. The magnetic lock assembly 400 can adsorb the sliding seat 210 so that the sliding seat 210 and the frame 100 are relatively fixed. The front end of the elastic member 110 is connected to the sliding seat 210.

[0046] Preferably, refer to Figure 4 and Figure 5 A guide block 150 is provided on the guide plate 140 , and the guide block 150 is provided with a guide through hole 151 . The slide bar 220 is passed through the guide through hole 151 . The slide bar 220 can move in the front-rear direction. The guide block 150 is used to support the slide bar 220 and the sliding seat 210 .

[0047] According to some embodiments of the present invention, referring to Figures 6 to 8The frame 100 is provided with an arc groove 120, and the guide plate 140 is provided with an arc slide rail 160 matching the arc groove 120. The arc slide rail 160 can slide in the arc groove 120 to allow the guide plate 140 to rotate relative to the frame 100 to drive the glue coating assembly 300 to rotate.

[0048] It is understandable that the edge sealing surface of the side of the plate 130 can be a vertical surface or an inclined surface with a certain angle to the vertical line. When the edge sealing surface of the side of the plate 130 is not a vertical surface, the guide plate 140 is deflected relative to the frame 100, thereby causing the translation assembly 200 installed on the guide plate 140 and the glue coating assembly 300 installed on the translation assembly 200 to rotate, thereby changing the axial direction of the glue coating shaft 320 to adapt to the edge sealing surfaces of the sides of different plates 130, and ensuring that the glue coating of the edge sealing surfaces of the plates 130 is uniform.

[0049] Preferably, refer to Figure 6 The bottom of the arc groove 120 is provided with a locking hole 121 penetrating the frame 100 , and the bolt can pass through the locking hole 121 to simultaneously press the frame 100 and the guide plate 140 so that the frame 100 and the guide plate 140 are relatively fixed.

[0050] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The magnetic lock assembly 400 includes a mounting frame 410 and an electromagnet 420. The mounting frame 410 is fixedly mounted on the frame 100, and the electromagnet 420 is fixedly mounted on the mounting frame 410. The lower side of the electromagnet 420 is attached to the translation assembly 200. When the electromagnet 420 is energized, the electromagnet 420 absorbs the sliding seat 210 of the translation assembly 200, so that the sliding seat 210 cannot continue to move in the front-rear direction.

[0051] According to some embodiments of the present invention, referring to Fig. 9 The distance between the front side of the positioning block 350 and the front side of the glue coating axis 320 along the front-to-back direction is X, which satisfies: 0.1mm≤X≤0.3mm, so as to ensure that the plate 130 can be evenly coated with glue during the gluing process.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
